The invention relates to the connection of the ends of the sheet of wood materials, in particular to the formation of a homogeneous grooves at the ends of the sheet of wood materials by rotational cutting tools and presser foot designed to correct the distortion on end parts mentioned sheet of wood materials, in order to make them durable and reliable connections.

As a rule, longer leaf wood materials are made by splicing the ends of such sheet of wood materials such as plywood, LVL beams, veneer, fiberboard, etc. using such adhesives, as termotehnica adhesive, thermoplastic adhesive, etc.

When this fusion does not provide end-to-end high durability due to the small space of the joined ends of the sheet of wood materials. Therefore, the handle end portion of the sheet of wood materials so that they are formed inclined surfaces for connections "on condition", with the aim of increasing the joined squares.

End part of the sheet of wood materials treated in this way, as mentioned above, are interconnected using, for example, adhesive, then they are heated or cooled in order to accelerate the hardening of the mentioned glue.

A known method of forming grooves n the ends of the sheet of wood materials, aimed at further increase of connected square end parts of the sheet of wood materials in the direction of their movement forward. When this groove is formed on the inclined surfaces of the sheet of wood materials.

That is, at the end parts of the two sheet wood materials subject to connection, to form, for example, V-shaped grooves formed in planes parallel to each other and inclined relative to the front and back sides mentioned sheet of wood materials in the direction of their end edges. Each of these V-shaped grooves extending in the direction of their end edges and disposed in the direction intersecting at right angles with the direction of their end edges.

When forming the above-mentioned grooves on the terminal parts of the two sheet wood shift the position of the grooves on one of the two sheet of wood materials relative positions of the grooves on the other by a distance equal to half the width of one groove, in the direction intersecting at right angles with the direction on said end edge, so close to splice mentioned grooves. Because if the location of the V-shaped grooves of the two sheet wood materials are the same, then the vertices of V-shaped grooves facing the other the other, that does not lead to a close bonding with each other.

The formation of grooves on the end portions of the sheet of wood materials, mentioned above, is performed in the following order:

As shown in Fig, on the outer circumference of the rotary cutting tool 3 are the cutting edges of the teeth 3a, located at a certain distance in the direction of rotation and directed in the direction intersecting at right angles with the direction of rotation, and they are opposite each other, in order to ensure the teeth.

The site for the formation of the grooves 11 is comprised of numerous cutting tools 3 placed in contact with each other in the direction of the axial line of the rotary shaft 2 and is attached to it. While the cutting edges of the teeth 3a are arranged on a spiral line, indicated in phantom line at Fig.

Have a site for the formation of the grooves 11 in the standby position indicated by a solid line in Fig(A), and rotate the rotary shaft 2 at high speed in the standby mode.

In addition, the site for the formation of the grooves 11 is able reciprocating movement between a position indicated by a solid line in Fig(A), and the position indicated by the dashed line, i.e. along a given path, inclined at a certain glam (for example, at an angle θ=10 degrees) relative to the surface of the sheet of wood material 210.

In the position shown Fig(A), move the sheet of wood material 210 by means of the transport roller 220 on the support table 215 to the site mentioned below (hereinafter referred to as the site of formation of the grooves), then stop and put it to standby mode.

That is, when the node is moved to form grooves 11 downward path mentioned above, cut a groove on the side of the sheet of wood material 210, on which the rotary cutting tool 3 passes. As a result, a sheet of wood material 210 appears the plot with the cut groove, which extends from the front side of a sheet of wood material 210 to its reverse side.

While the above plot, where a sheet of wood material 210 is stopped and is in the standby mode, is the site of formation of the grooves.

As shown in Fig so formed by cutting numerous V-shaped grooves 210A located parallel to each other.

Meanwhile, the support table 215, shown in Fig(A)which is made of such material as synthetic resin, etc. with sufficient rigidity and hardness, but unable to damage the cutting edges of the teeth 3a of the cutting tools 3 pria collision with a support table 215.

And the support table 215 previously exposed to cutting grooves as mentioned below.

That is, fix a leaf element with a given thickness on the substrate, not shown in the figure, thus, as shown in Fig(A). After that move the node to form grooves 11 sloping down the path, parallel to the above-mentioned way, so at first slightly cut into the groove on the said sheet element.

Then again move it sloped down from the more left start position than the position of the beginning of the above-mentioned way, if you look at Fig(A), the path parallel to the above, in order to cut the groove deeper and fully on the said sheet element.

Several times I repeat the cutting process until the formation of such grooves a, as shown in Fig, and thereby form a path suitable for passage of a site for the formation of the grooves 11 when cutting grooves in a sheet of wood material 210.

In the support table 215 can support sheet of wood material 215, except it cut parts when the node is moved to form the grooves 11.

As shown in Fig(A), the cutting of grooves on another sheet of wood material, joined with a sheet of wood material 210 is, for example, in the following the m order.

As shown in Fig(A), stop another sheet of wood material mentioned above, in the above-mentioned area for formation of the grooves and move it in the direction intersecting at right angles with the direction of the mentioned end edge at a distance equal to half the thickness of the cutting tool 3.

Then by moving the node to form grooves 11 carry out the cutting of the grooves mentioned on another sheet of wood material. After this turning the other sheet of wood material face down and glue connecting part with the cut grooves with a portion with the cut grooves sheet of wood material 210.

The disadvantage of the above method lies in the fact that it is impossible to solve the following problems, if at the end of the sheet of wood material 210 in the direction intersecting at right angles with the direction of its end region, has a warped portion 210b, indicated in phantom line with two points on Fig(A), and a solid line on Fig(B) (front view of the end portion on the right side).

That is, if you produce cutting grooves in a sheet of wood material 210 such pokoroblennost, are formed too deep groove on the warped part 210b, when compared with grooves sheet etc is LESNOGO material 210, formed normally.

As a result, when the connection is cut grooves on the warped part of the sheet of wood material 210 with fine cut grooves of another sheet of wood material are formed gaps between the surfaces of the cut grooves.

Therefore, if using the glue connecting the said surface with each other, do not provide sufficient bond strength, which leads to the separation of conjoined parts from each other when exposed to a force from the outside.

In the present invention is to form sequentially numerous grooves mentioned above, the end portion of the sheet of wood material repeatedly move the rotary cutting tools, such as disc cutters and other

The technical result of the invention is the alignment of the warped portion at the end portion of the sheet of wood material by clamp mentioned end portion to the support table through the presser foot, at least, in a single movement mentioned rotary cutting tool.

The solution of the task set in the invention, is achieved by the fact that, at least, once they carry out the formation of the groove on the end portion of the mentioned sheet of wood material is the exploits of the rotary cutting tool provided what warped area on said end portion aligned with the presser foot. Due to this is not too deep cutting, the result of which are provided with the same size and shape of the grooves.

In addition, attach the movable element 14a, moving on a stationary element 14b, to the underside of the stand 7, so that each stand 7 is moved in the downward direction.

The left ends of both screws with outer thread 10, shown in figure 2, join to 1st servomotors 15, which are controlled by the signals transmitted from the device management the ia 70, mentioned below. By controlling the aforementioned servo motors both screw with an external thread 10 is provided in a reciprocating motion and stop in synchronous mode.

When forward movement of both screws with outer thread 10 site for the formation of the grooves 1 moves from the position (hereinafter referred to as the stand by position)indicated by the solid line in figure 3, in the downward direction to the position (hereinafter referred to as a front-line position)indicated by the dashed line in figure 3. And when they return movement of the said node is returned to the standby position.

Meanwhile, the supporting block 6, shown on the upper side of figure 1, attach the console 16, protruding to the side. On the console 16 is fixed 2nd servo motor 18 and attach it to one of both ends of the rotary shaft 2 located on the upper side of figure 1. Referred to the servo motor 18 is controlled by signals sent from control device 70, described below, in order to cause the rotary shaft 2 in rotation in the direction indicated by the arrow in figure 2, and shutdown.

Usually the 2nd servo motor 18 is in a stopped state, but he is driven into rotation in the direction indicated by the arrow in figure 2, the signals transmitted from control device 70, before moving the node to generate Kahn is OK 1 with the aim of forming grooves on a sheet of wood material 62, and after its unilateral move - in shutdown.

In addition, the frame 9 with the individual elements mentioned below are located on the 1st base 20.

As shown in figure 1, part number 22 represents the 1st support wall located on the upper surface 1 of the base 20, with the height indicated in phantom line with two dots on figure 3. Both 1-m supporting walls 22 are attached at both ends of the 1st rotor shaft 24.

In the 1st prizim is I foot 34 is free to move relative to the 1st of the lever 28.

The bottom part of the 1st presser foot 34 has two types of surfaces mentioned below.

As shown in figure 5, one of the two species is the flat surface 34a on the bottom part designed to clamp to the flat surface of the sheet of wood material 62, which has not yet formed the 1st groove a and 2nd grooves s mentioned below.

And the other is inclined surfaces 34b formed on both lateral sides of the flat surface 34a, as shown in figure 5.

As shown in figure 11, the inclined surface 34b are designed for full contact with the inner surface 62b of the 1st groove a when the clamp 1 presser foot 34 inside the 1st groove a formed on the sheet of wood material 62.

Part number 36, shown in figure 3, is a weak spring tension connected with 1-m lever 28 and the 1st presser foot 34.

If 1, the presser foot 34 without the said spring is set only through the bearing on the 1st lever 28, it is possible that, for example, at the turn of the 1st lever 28 1-I, the presser foot 34 is rotated around the bearing, resulting in the left part of the 1st presser foot 34 in the 2nd direction goes down and remains down.

In this situation, as mentioned above, when applying a sheet of wood material 62 to the position of formation of the grooves listvideos material 62 hits the presser foot 34 and can no longer move.

In order to avoid this phenomenon set the spring tension 36 on the 1st lever 28 so that when the 1st position of the lifting of the 1st lever 28, indicated by the solid line in figure 3, the tension spring 36 is slightly raised left part of the 1st presser foot 34 to tilt upward to the left.

Meanwhile, figure 3 shows the status of the 1st cylinder 32 when the piston rod 32A pulled back, while with his nomination 1st presser foot 34 is pressed against the smooth surface of the sheet of wood material 62 or the inner surfaces of the grooves 62b.

In this case, all the steps mentioned above, are controlled by signals sent from the control unit 70.

Part number 42 is a support table with flat surfaces on its front and back sides, used in the processing of sheet wood material 62 and is made of steel.

In the space formed in the cut, fix the damper 43 to the cutting tool 3 from materials such as bakelite, hard synthetic resin, etc. having not only hardness but also properties that prevent damage to the cutting edges of the teeth of the cutting tools 3 in contact with the said amortizat the rum.

As shown in figure 3, the 1st support table 42 is located on the 1st base 20 and is able to move in 1 direction intersecting at right angles with the direction of feed of sheet wood material 62 (hereinafter referred to as the 2nd direction)indicated by the arrow in figure 3.

On the upper surface 1 of the base 20 have through a certain distance two Adjuster 44 and fix them. On each Adjuster 44 has a fixed element 46b, which together with the movable element 46a is part of the 2nd bearing linear motion 46, and the movable element 46a is fixed on the bottom surface 1 of the support table 42.

Part 1 of the support table 42 can move in 1 direction includes the following elements.

Part number 48 represents the 2nd pneumatic cylinder, which is partially shown as a solid line, and primarily by the dashed line in figure 1. And he fully shown by the dashed line in figure 2 and presented in the context of figure 3.

Its end part is attached by a pin to the 1st base wall 22 of the frame 9, while the end of its piston rod 48A is attached by a pin to the 1st ledge 20A mounted on the bottom surface 1 of the support table 42.

In such composition, as mentioned above, the 1st support table 42 is moved in the 1st direction when in the movement and retraction of the piston rod 48A of the 2nd cylinder 48.

Thus have two stoppers of known type, designed to stop the 1st reference table 42 in a predetermined position waiting (hereinafter referred to as the 1st position), distant at a distance T in the 1st direction and is shown on the lower side of figure 1, when the retraction of the piston rod 48A, and is in a predetermined position expectations (hereinafter referred to as 2nd position)shown on the upper side of figure 1, with the extension of the piston rod 48A.

Moreover, steps 2 pneumoslide 48 are controlled by signals sent from the control unit 70.

Part number 50, shown in figure 3, is a limiter with a sharp tip.

The limiter 50 is located as listed below.

Part number 52, shown by the solid line in figure 1, and figure 3 - dot-dashed line represents the 3rd supporting wall, each located vertically on the upper surface 1 of the support table 42 in the 1st direction, that is, at its both ends in the direction from top to bottom of figure 1.

Both 3-m support walls 52 are attached to both end of the 2nd rotor shaft 54.

On the left side of figure 3 is 4-I support wall 55 that is attached at both ends, in the direction from top to bottom of figure 1, both the 3rd bearing walls 52.

2nd levers 58 can be rotated, the lower ends of which are limited to the ate 50, located at a certain distance in the downward direction, as shown in figure 1, on the 2nd bearing shaft 54 together with the bearings 56.

As shown in figure 3, the upper ends of the 2 levers 58 are connected by pins with the ends of the piston rods 60A 3 pneumatic cylinders 60, the ends of which are attached by pins to the 4th support wall 55.

When the extension and retraction of the 3 cylinders 60 2nd levers 58 are rotated within the area between the position indicated by the solid line in figure 3 (hereinafter referred to as the 2nd position lift), and a position indicated in phantom line with two dots in figure 3 (hereinafter referred to as the position of sticking), where the ends of the stoppers 50 are stuck to the surface of the sheet of wood material 62 to limit its movement by clamping between the limits of 50 and 1st reference table 42.

However, the situation of sticking is not constant due to the following reasons. The stops 50 are intended to prevent displacement of the sheet of wood material 62 due to the force produced by forming grooves in a sheet of wood material 62 by means of cutting tools 3, by sticking the ends of the stops 50 in the surface of the sheet of wood material 62.

Therefore, the power of sticking caused by 3-m pneumatic cylinder 60, is changing at an appropriate time in order to ensure the fully the prevention of the offset sheet of wood material 62.

When turning the 2nd lever 58 actual position of sticking limiter 50 is changed depending on the force caused by the 3rd cylinder 60, the properties sheet of wood material 62 and other

The actions of the 3rd cylinder 60 is controlled by signals sent from the control unit 70.

Part number 62, shown in phantom line with two points on 1 and solid line in figure 3 represents a sheet of wood material, which formed the 1st groove a and 2nd grooves s by the cutting tools 3 as mentioned below.

As shown in figures 1 and 3, part number 64 represents a transport roller that is designed to transport a sheet of wood material 62 on the 1st reference table 42. Figures 1 and 3 shows only one transport roller 64, but in practice many of the transport rollers 64 are in place.

The transport roller 64 is driven into rotation and stop by the 3rd servo motor 66.

Part number 68 is a sensor for detecting the front end of the sheet of wood material 62 and transmit the detection signal to the control device 70.

The control unit 70 after receiving the detection signal from the sensor 68 transmits the control signals to individual work items.

In this part, as you mentioned the e, pre-formed grooves in the 1st reference table 42.

That is, first attach the 1st support table 42 without grooves, the shape of the upper corner on the right edge of which is shown in phantom line with two dots on figure 3, the 2nd bearing linear motion 46.

In this situation, as mentioned above, draw back 2 pneumatic cylinder 48 to move the 1st support table 42 to the 1st position and put it in standby mode.

Then result in rotation of the 2nd servo motor 18 to rotate the cutting tool 3 in the direction of the arrow indicated in figure 3. After that result in translational movement of the screw with an external thread 10 through the 1st servo motor 15 to move the node to the formation of the grooves 1 in the front position, as shown in figure 3.

And after a shutdown of the 2nd servo motor 18 result in the return movement of the 1st servo motor 15 and thereby produce reverse rotation of the screw with an external thread 10 with the aim of moving the node to form grooves 1 to the standby position.

After the process mentioned above, push forward the 2nd pneumatic cylinder 48 to move the 1st support table 42 in 2nd position and put it in standby mode.

Also, as mentioned above, the rotating cutting tools 3 in the direction of the arrow indicated in figure 3, move the node f is Mirovaya grooves 1 in the front position, shown in figure 3.

As a result, as shown in Fig.6 with perspective views, on a support table 42 are formed a lot of V-shaped grooves 43a, consisting of two inclined inner surfaces 43b and located through the distance T in the 1st direction, and each respective form of the cutting edge of the tooth of the cutting tool 3.

Now let's explain the sequence of actions of individual work items in the main example.

As a source of provisions previously have a separate work items as mentioned below.

That is, draw back the piston rod 32A of the 1st cylinder 32 to move the 1st lever 28 to the 1st position of the hoist, shown by the solid line in figure 3.

As well as push forward the 3rd pneumatic cylinder 60 to move the 2nd lever 58 to the 2nd position of the hoist, shown by the solid line in figure 3.

Pull back the 2nd pneumatic cylinder 48 to move the 1st support table 42 through the 2nd bearing linear motion 46 in 1st position.

Lead transport roller 64 to rotate in the direction of the arrow indicated in figure 3 by the 3rd servo motor 66.

In this situation, as mentioned above, put a sheet of wood material 62 on the transport roller 64 and carry it in the 2nd direction.

When the front end of the sheet d is eveslage material 62, transported to the right side (figure 3), is detected by a sensor 68, the detection signal from the sensor 68 is transmitted to the control device 70.

Then, the control unit 70 outputs a signal stop, first of all, to the 3rd servo motor 66 in order to stop the transport roller 64 when the front end of the sheet of wood material 62 is slightly beyond the left boundary of the site with grooves 43a formed on 1-m support table 42, when viewed from the front 3.

The control unit 70 outputs the signals in order to put forward the piston rods 32A 1-s pneumatic cylinders 32, and also to pull back the 3rd pneumatic cylinder 60.

Under the action of 1-s pneumatic cylinders 32 are each 1-s lever 28 is driven in a clockwise direction from the position shown in figure 3.

As a result, as shown in Fig.7 is an enlarged view, flat surface 34a of the 1st presser foot 34 presses the sheet of wood material 62 to the 1st reference table 42.

That is, even if partial buckling sheet of wood material 62 has, then it is corrected and warped plot is aligned in this way, as mentioned above.

And under action 3 of the pneumatic cylinders 60 each 2-s lever 58 is driven in a counterclockwise direction from the position shown by the solid line in figure 3.

In the edge stops 50 are stuck to the surface of the sheet of wood material 62.

Then, the control unit 70 outputs a signal to trigger the 2nd servo motor 18 with the purpose of rotation of the rotary shaft 2 of the site for the formation of the grooves 1, that is, the cutting tools 3 in the direction indicated by the arrow in figure 3.

After that, the control unit 70 generates signals to actuate both 1-s servo motor 15 with the aim of bringing both screws with outer thread 10 in the forward movement in synchronous mode.

As a result, as shown in figure 3, the node for forming grooves 1 is moved from the position waiting to front-line position.

Moving the front end portion of the sheet of wood material 62 is subjected to cutting by the cutting tools 3.

As shown in Fig and 9, at each stage of cutting, forming the width of 2T, a sheet of wood material 62 are formed 1st groove a, consisting of two inner surfaces 62b, as shown by the inclined lines, and having each a width T in the 1st direction and V-shaped in section in the direction intersecting at right angles with the oblique direction,

1, the presser foot 34 is shown as a solid line on the upper side Fig, and only her flat on Ernest 34a and the inclined surface 34b - the dash-dotted line with two dots on the underside Fig.

During the cutting process by the cutting tools 3 1-I, the presser foot 34 is pressed down to a sheet of wood material 62.

While moving the cutting tools 3 occurs freely as grooves 43a, formed in advance on the 1st reference table 42 are space for passage of the cutting tools 3.

While the inner surface 62b of the 1st grooves a, thus formed, as mentioned above, and the inner surface 43b of the grooves 43 are parallel to each other and comprise as least one solid surface.

When forming the grooves a front end portion of the sheet of wood material 62 is aligned with the 1st presser foot 34 and is clamped between the 1st presser foot 34 and 1-m support table 42, so it does not shifted from the predetermined position, resulting in almost identical in size and shape of the 1st groove a are provided.

In addition, the offset sheet of wood material 62 is prevented and by limiters 50.

In addition, the reverse side of a sheet of wood material 62, with the exception of its parts, through which the cutting tool 3 is supported on the 1-m support table 42, making grooves 1st a formed more correctly.

The mouth of austo control 70 after a sufficient time, necessary for the formation of 1's grooves a, outputs a signal to operate the individual work items.

That is, pull back piston rods 32A 1-s pneumatic cylinders 32 and thereby return the 1st levers 28 to their original positions shown in figure 3.

After that push forward the piston rod 48A of the 2nd cylinder 48 to move through 2nd bearings linear motion 46 1 support table 42 from the 1st position to 2nd position at a distance So

When this move and 3 and the supporting wall 52 together with the support table 42, resulting in a sheet of wood material 62, in which is stuck limiters 60, without changing its position relative to the 1st reference table 42 moves together with the said support table 42.

After this move, each of 1's grooves a formed on a sheet of wood material 62, is located right under the 1st presser foot 34 as shown in figure 3.

Then, the control unit 70 outputs a signal in order to put forward the piston rods 32A 1-s pneumatic cylinders 32.

In the 1st levers 28 is again rotated in the clockwise direction from the position shown in figure 3.

Therefore, the 1st pressure foot 34, mounted on the 1's levers 28, pressed to the 1st grooves a, tilted down as shown in Fig.

To the lower part 1 of the installation unit 88 is attached 3rd supporting element 94, the speaker in the right side of the 2nd direction.

Near the edge of the 3rd support element 94 installing the bearing 96, where insert the 3rd bearing shaft 100 extending from both lower ends of the 4-th of the support element 98 in the 1st direction. In the 4-th reference element 98 can rotate around the 3rd bearing shaft 100.

As shown on one side only on Fig, in the space between the end 88p 1 mounting block 88 and the end 98S 4th of the support element 98, pointing towards the 1st direction, and have a 4-th pneumatic cylinder 102 with the possibility of free rotation.

The end 102A of the 4th mo is macilenta 102 is attached via a bearing (not shown in Fig.) to the end 88p, and the end of the piston rod 102b to the end of the 98S.

In addition, as mentioned below, at the maximum extension of the piston rod 102b flat surface 108A of the 2nd presser foot 108 becomes parallel to the inclined path of travel site for the formation of the grooves 1.

Therefore, when the extension and retraction of the piston rod 102b of the 4th cylinder 102, is controlled by signals sent from the control unit 120, 4th support element 98 is rotated around the 3rd bearing shaft 100.

4th supporting element is provided with the following elements.

Part number 104 is a 4-th bearing linear motion, the stationary part 104b which is attached to the right surface of the 4th support element 98, aimed in the direction of the 2nd direction. While many fixed part 104b are arranged through the distance T in the 1st direction.

As shown in Fig and 13, each of the fixed parts 104b is set via the movable part a on the 5th of the supporting element 106. 5th supporting element 106 has the capability of lifting up and lowering down relative to the 4th support element 98.

To the surface of the 5th of the support element 106, the opposite surface with a moving part a, attached 3rd lever 107, shown by an L-shaped form on Fig, and the dash-dotted line with two points on Fig(a), the rich, the width mentioned the 3rd lever 107 in the 1st direction is equal to the thickness of the 1st presser foot 34, given in the above basic example implementation.

As shown in Fig, 2-I, the presser foot 108, which is part of the 3rd lever 107, acts in the horizontal direction on the bottom 3rd of the lever 107.

As 1st presser foot 34, the design of the bottom part of the 2nd presser foot 108 consists of a flat surface 108A and inclined surfaces 108b, such as shown in Fig with enlarged perspective view, when viewed from the side of the arrow H on Fig.

As shown in Fig and 13, to the upper surface of the 4th support element 98 that is located relative to the stationary part 104b, attached 2nd installation unit 110.

On the upper end of the 2nd installation unit 110 is fixed to the adapter 110A with the 2nd protrusion 110b.

Part number 112 is a 5th pneumatic cylinder, the end 112b of which is connected with the protrusion 110b, and the end of the piston rod a connects with the top surface 5 of the first support element 106.

In this arrangement, as mentioned above, the piston rod a 5th pneumatic cylinder 112 extends or retracts according to the signals transmitted from the control unit 120. In the 3rd lever 107 is lifted up or lowered down.

Part number 62 is a sheet of wood material, as in the above basic example implementation.

As well as the part number 64, not only is em a transport roller to rotate and stop by the 3rd servo motor 66.

Part number 68 is a sensor for detecting the front end of the sheet of wood material and the transmission of detection signal to the control device 120.

The control unit 120 receives signals from the sensor 68 and generates control signals for the individual work items.

Part 1 is a host for the formation of grooves in the composition of such elements, as in the above main embodiment, can move in the area between the standby position and the front position. At Fig displays only the stand by position indicated in phantom line with two points.

As a source of provisions previously have a separate work items as mentioned below.

That is, by the 4th servo motor 92 to move the 1st mounting block 88 to the position (hereinafter referred to as the initial position)indicated on Fig.

By means of respective pneumatic cylinders move the 2nd lever 58, 4th support element 98 and 5th supporting element 106 to the provisions (hereinafter referred to as the initial position)specified on Fig.

As in the above main embodiment, move the node to form grooves 1 to the standby position.

In addition, the involvement of the 2nd cylinder 48 to move the 2nd on the a priori element 80 to the 1st position.

By the 3rd servo motor 66 lead transport roller 64 to rotate in the direction of the arrow indicated on Fig.

In this situation, as mentioned above, on the transport roll 64 is transported sheet of wood material 62 in the 2nd direction. If the leading end of the sheet of wood material transported in the 2nd direction to transport the roll 64 is detected by a sensor 68, the detection signal from the above-mentioned sensor is transmitted to the control device 120.

Then, the control unit 120 outputs a signal stop, first of all, to the 3rd servo motor 66 in order to stop the transport roller 64 when the front end of the sheet of wood material 62 is slightly beyond the left boundary of the site with grooves a formed on the 1st reference table 80, when viewed from the front Fig.

However, the control device 120 after receiving the detection signal from the sensor 68 outputs a signal and the 2nd servo motor 18 in order to cause the rotation of the cutting tools 3 installed in the node for the formation of the grooves 1, as described in the above basic example implementation.

Then, the control unit 120 after a sufficient time required to stop the transport roller 64, and outputs a signal to pull back the 3rd pneumatic cylinder 60 and thereby turn the ü 2nd lever 58 with the aim of sticking sharp tip of the stopper 50 in the surface of the sheet of wood material 62 so that as shown in figure 3.

And the control unit 120 outputs a signal to the 5th edition of the pneumatic cylinder 112 so as to lower down the 3rd lever 107 and with its flat surface 108A to press the front end portion of the sheet of wood material 62 to the 2nd reference table 80 thus, as shown in Fig.

After that actuate both 1-s servo motor 15 so as to cause linear movement both screw with an external thread 10 in synchronous mode.

As a result, the site for the formation of the grooves 1 is moved in the downward direction indicated by the arrow on Fig, from the position of waiting to the front-line position indicated by the dashed line in Fig.

Simultaneously with the start of moving the node to form grooves 1 result in translational movement of the screw with an external thread 90 through the 4th servo motor 92 to move the mounting block 88 in the 2nd direction indicated by the arrow on Fig, keeping a certain distance from the node to the formation of grooves 1 2-m direction.

3rd lever 107 is moved in the 2nd direction together with the 1-m mounting block 88 has a flat surface 108A and the inclined surfaces 108b. As shown in Fig mentioned surface fit in the 2nd direction to a more forward position than the node for the formation of the grooves 1.

Therefore, through the om 2nd presser foot 108 of the end portion of the sheet of wood material 62 is pre-pressed to 2nd reference table 80 before forming grooves on the said end portion of sheet material wood 62 using cutting tools 3 forming part of the site for the formation of the grooves 1.

Meanwhile, through the 4th servo motor 92 stops the forward movement of the screw with an external thread 90 to stop moving the 1st installation of block 88, when the forward end of the 2nd presser foot 108 comes to a slightly more anterior position (hereinafter referred to as the 3rd position)than the end part of the sheet of wood material 62, as shown in Fig.

While both 1-s servo motor 15 continues to rotate and stop in the arrival time of the node for forming grooves 1 to the position indicated by the dashed line in Fig.

As a result, as mentioned above in the main embodiment, even if there are warping mentioned end portion of the sheet of wood material 62, it is corrected and thereby the mentioned end portion is aligned. That is, without hogging the processing of the sheet of wood material 62 cutting tools 3.

As shown in Fig shown in the above main embodiment, at each stage of cutting, forming the width of 2T, a sheet of wood material 62 are formed 1st groove a having each a width T in the 1st direction and V-shaped in section in the direction intersecting at right angles with nuklon the m direction.

Meanwhile, when the node is moved to form grooves 1, each of the cutting tools 3 passes the area between the 3-mi levers 107, located at a certain distance next to each other, so the 3rd levers 107 do not interfere with the movement of the cutting tools 3.

When this site for the formation of the grooves 1 is a front-line position in the standby mode.

The control unit 120 after a sufficient time required for the formation of 1's grooves a, generates signals to operate the individual work items as mentioned below.

That is, draw back the piston rod a 5th pneumoslide 112 in order to raise up the 3rd lever 107 to the position specified on Fig.

After the maximum push forward the piston rod 102b of the 4th cylinder 102.

Then the 4th support element 98 is rotated around the 3rd bearing shaft 100 to the 4th support element 98 leaned on the 1 St of the installation unit 88 as shown in Fig.

Pre-adjust the individual elements so that the forward end of the 2nd presser foot 108 came across a sheet of wood material 62, but even if this occurs, the sheet of wood material 62 is not offset from the 1st installation of the block 88 in connection with the fact that the stops 50 are stuck in the surface of listowel the wood material 62.

And after returning the 3rd lever 107 to the position indicated on Fig, push forward the 2nd pneumatic cylinder 48 to move the 2nd support table 80 on the distance T to the 2nd position and put it in standby mode.

And while moving sheet of wood material 62, without changing its position relative to the 2nd of the support element 80 is moved together with him, because the stoppers 50 are stuck to the surface of the mentioned sheet material as described in the above basic example implementation.

Then by the 4th servo motor 92 lead in the forward movement of the screw with an external thread 90 in order to move the 1st mounting block 88 to the position indicated on Fig, that is, to the position (hereinafter referred to as the 4-th position), where 1-e grooves a sheet of wood material 62 is directly below 2 s clamping pads 108.

Then by forward displacement of the 5-s pneumatic cylinders 112 down 3 levers 107, so that, as shown in Fig, the inclined surface 108b 2's pressure feet 108 clung to the 1st grooves a is the same as shown in figure 11 above basic example implementation.

Therefore, if the warping end portion of the sheet of wood material 62 has, then it is corrected in this way, as mentioned above, and the above-mentioned end part in ravniaetsia.

After that, the control unit 120 outputs a signal to actuate both 1-s servo motor 15 and thereby result in the return movement of both screw with an external thread 10 in synchronous mode.

As a result, the site for the formation of the grooves 1 moves from the front position, shown by the dashed line in Fig, to the standby position, shown in phantom line with two points.

Moving the front end portion of the sheet of wood material 62 is subjected to cutting by the cutting tools 3. As shown in Fig.9, is given in the above main embodiment, at each stage of cutting, forming the width of 2T, the sheet of wood material 62 are formed 2-groove s having each a width T in the 1st direction and V-shaped in cross section, is formed in the direction intersecting at right angles with the oblique direction.

That is, as in the above main embodiment, the front end portion of the sheet of wood material 62 are formed in the same size and shape of the 1st groove a and 2nd grooves s.

Meanwhile, when the node is moved to form grooves 1, each of the cutting tools 3 passes the area between the 3-mi levers 107, located at a certain distance is poison to each other, therefore, the 3-and the levers 107 do not interfere with the movement of the cutting tools 3.

When joining two sheet of wood materials overturn one of them face down and glue connecting part with the cut grooves with a portion with the cut grooves of the other sheet of wood material.

The result is a solid and reliable connection of the end parts of the sheet of wood materials without gaps.

Example 2:

In the above examples, the implementation of the 1st groove a and 2nd grooves s are formed in a single progressive-return the node is moved to form grooves 1, but in this example, grooves are formed by the following method.

In this case, you use this site for the formation of grooves in which are located, for example, 3 spacers (three pieces) 4 between every two cutting tools 3 on the rotary shaft 2.

As in the above embodiments, progressive-relapsing move this node to form grooves 1 between the standby position and the front position is carried out twice. Each time after unilateral move the site for the formation of the grooves 1, for example, a sheet of wood material moves in 1 direction.

Therefore, reducing the number of cutting tools is having in contact with the sheet of wood material, can reduce the resistance provided by the site for the formation of the grooves 1 in General, when forming grooves on a sheet of wood material, which reduces the mechanical load on the mentioned site. The result is almost not there fault this node, allowing easier maintenance and care of the said node.

Example 3:

1, the presser foot 34 and 2-I, the presser foot 108 have a flat surface 34a and the inclined surface 34b. For example, as shown in the section of figure 11, 1-I, the presser foot 34 has a flat surface 34a and the inclined surface 34b. With this design mentioned presser foot allows you to stay as close as to the flat surface of the sheet of wood material 62 and the groove.

But the shape of the structure mentioned presser foot is not limited to the above. In this example, for example, as shown in the circle on the right upper side 11, is used 3rd presser foot 35 with a curved bottom part 35A.

Example 4:

In the above examples, the implementation of the pressure pads located at both side areas adjacent to the cutting tool 3, in the direction intersecting at right angles to the direction of movement of the cutting tool 3, pressed flat on top of the awn sheet of wood material 62 and the inner surface of its groove to the 1st reference table 42 or 2nd reference table 80 with the to provide a plane surface of the sheet of wood material 62 in the formation of the 1st grooves a and 2's grooves s by the cutting tools 3.

But in the case of relatively thin sheet of wood material or legkodeformiruemyh material, it is preferable that only the presser foot is located on one of both side portions adjacent to the cutting tool 3, in the direction intersecting at right angles to the direction of movement of the cutting tool 3, pressed sheet of wood material 62 to the mentioned reference table.

Example 5:

1, the presser foot 34, shown in the above main embodiment, and 2nd, the presser foot 108 shown in additional exemplary embodiment 1, each have a flat surface that is pressed against the upper surface of the sheet of wood material 62, and the inclined surface, pressed against the inner surfaces of the grooves.

But despite the complexity of the design of the device, in this case, have the presser foot, with only a flat surface, and the presser foot, with only the inclined surfaces. They move separately and independently from each other and pressed to the places mentioned above.

Example 6:

In the main embodiment, and dopolnitelniie implementation 1 two screws with outer thread 10, equipped with every 1st servo motor 15, are rotated in order to move the node to form grooves 1.

But in this case, set the bevel gear on the right ends of the two screws with outer thread 10, the opposite parties, where there are 1's servo motors 15.

And connect the driven shaft to transmit rotation, provided with bevel gears on its both ends, coinciding with the said bevel gears, right angle with both screws with outer thread 10.

In addition, remove one of the two 1's, servo motors 15 and through the remaining one of the 1st servo motor 15 is put into rotation of one screw with an external thread 10.

Thus, the rotation of the screw with an external thread 10 right from the 1st servo motor is transmitted through the driven shaft for transmitting rotation to the screw with an external thread 10, located on the other side. As a result both of the screw with an external thread 10 are rotated synchronously with each other, and the axial direction of the rotary shaft 2 is crossed at a right angle to the direction of movement of the node for the formation of the grooves 1. This ensures proper formation of the grooves.

Example 7:

In the main embodiment, and in an embodiment 1 in the formation of the 1st grooves a node d is I the formation of the grooves 1, for example, as shown in Fig, moves from the position of the expectations indicated in phantom line with two points, to the front-line position indicated by the dashed line, and when forming the 2's grooves s, for example, as shown in Fig, moves from the front position to the standby position.

In this case, the above-mentioned movements are the opposite. That is, when forming the 1st grooves a, as shown in Fig, the site for the formation of the grooves 1 moves from the front position indicated by the dashed line, to the stand by position indicated in phantom line with two points, and when forming the 2's grooves s, as shown in Fig, the site for the formation of the grooves 1 is moved from the position of the expectations indicated in phantom line with two points, to the front-line position indicated by the dashed line.

The machine forming the grooves have a rotary cutting tools 3 many, each having a thickness L1 in a direction parallel to the end edge of the mentioned sheet of wood material, and constituting the group of rotary cutting tools. Suppose that m is an integer equal to or greater than 1. There have rotary cutting tools 3 many so that the distance between neighboring with each other wrastlin the mi cutting tools 3 are mL1.

This moves the group of rotary cutting tools on the said sheet of wood material in the direction perpendicular to the mentioned end edge and inclined relative to the front and back sides mentioned sheet of wood material, which cut grooves on said sheet of wood material. Then move the above group of rotary cutting tools relative to the sheet of wood material as mentioned below.

Suppose that n is an integer equal to or greater than 1. That is, move the group of rotary cutting tools wood and sheet material relative to each other at a distance of nL1 in a direction parallel to the mentioned end edge of the sheet of wood material. Then again move the group of rotary cutting tools on the said wood material in said oblique direction and thereby cut grooves on said sheet of wood material.
