Prior art

Printer manual labeling machine usually contains wheel selector mounted on the shaft at the end of the frame of the printing device, and a section of a support letter to the other terminal of the frame. Endless print belt made of elastic material such as rubber or synthetic resin, and having on their outer surfaces and muscular and excretory font, pass around the selector wheels and sections of support letters. The selector wheel is turned to rotate the endless printing bands to accommodate the desired characters on the outer surfaces of the support section of characters, these characters can be printed, and the printing ink is applied to the letters (font) using colorful roller or similar, and then the letters can be pressed against the label or etc.

Each of the endless print belt made from the letters around one half of its perimeter and secretory type around the other half of its perimeter, the arrangement is such that the sign of the excretory font in the position in which his mo is on its section of the support characters.

Thus, it is possible to arrange the specified letters of support section of characters using the shaft of the choice of characters used to turning the selector wheel, together with the observation excretory font through the viewing window.

However, if the endless print belt rotate beyond the specified area of the turn with the shaft of choice liter, excretory font can be rotated to a section of a support character and there will be polluted by applying to it the print colors with a colorful cushion. This leads to difficulties, since the excretory font becomes difficult to see when selecting a set of characters with a simultaneous view of the excretory font in the viewing window.

It was suggested various solutions to prevent this contamination excretory font (by means of preventing the application of the printing ink). In "the structure of the print tape according to the Patent Publication Japan N Sho 62 (1987)-33080, for example, the rotary drive for rotating the endless print belt includes a ledge, and also provides a stop near the turn of the endless print belt. In the seal lip to stop the rotary disc can be rotated only within a given the network interference excretory font and that, when the rotary disk to rotate with excessive force after the protrusion reaches the stop, the infinite, the print tape can be stretched, which leads to incorrect printing or defect.

In addition, in the "printing device" according to the Patent Laying Japan N Hei 6 (1994)-155878 on the outer peripheral surface of the endless print belt made ledge posted interoperable with emphasis, and the upper surface of the drive protrusion, a member in engagement with the teeth provided on the perimeter of the selector wheels, made in the form of an inclined surface. If the selector wheel with power turn after endless print belt has reached the limit position, the endless print belt slips.

However, this printing device has the disadvantage that when slippage during rotation of the excessive force of the endless print belt its inclined surface wear, cracks or gets other damage.

In addition, since the outer peripheral surface of the endless print belt is made with the tab, the above-mentioned disadvantage is compounded by the fact that decreases the number is I prevent pollution excretory font of the printing device according to the Layout No. 6 (1994)-71146 the Application for a utility Model in Japan, the region of rotation of the endless print belt is limited by contact thicker in cross section part of the letter, formed on the outer perimeter of the endless print belt with the supporting part of the indicator.

The disadvantages of this device include damage to the indicator and damage to the endless print belt by cracking under the application of excessive force rotation. Another disadvantage is that the endless printing ribbon can pass underneath the bar.

In "printing device" according to the Patent Publication Japan N Hei 4 (1992)-34951, on the other hand, the rotation of the endless print belt is limited by its engagement between the teeth formed on the endless print belt, and thrust his shoulder.

This printing device also has the disadvantage that the application of excessively large force of rotation causes the tension of the endless print belt and causes wear, cracking and other damage.

Thus, in all these designs attempt to prevent contamination of the urinary font by limiting the rotation of the endless print belt scoped creates difficulties in preventing the effects of direct and indirect large external forces on the endless printing is K. the tabs pass over the lugs, and other problems.

The present invention was created to resolve the above problems.

The aim of the present invention is to provide a printing device which prevents contamination of the excretory font on the endless print belt by preventing their installation in the support section of characters, i.e., from falling in contact with a colorful cushion.

Another objective of the invention is to provide a printing device in which the rotation of the endless print belt is limited in such a way that the applied excessive force rotation does not act on the endless print belt and thereby prevents deterioration, cracking and other damage.

Another objective of the invention is to provide a printing device which makes a minimal decrease in the number of characters caused by the execution of the protrusion to limit rotation of the endless print belt.

Another objective of the invention is to provide a printing device in which the power rotation of the endless print belt limiting rotation causes the idle rotation selecting the acquisition is the creation of the printing device, in which stretching (the degree of tension of the endless print belt can be adjusted within a specified area.

The invention

The first aspect of the invention is directed to the provision of the idle rotation of the selector wheels using software floating elements, limiting the rotation of the selector wheel (movable locking elements) having an elastic part, which allows a movable locking elements to move, when an excessive force acts on the selector wheel or endless printing belt, and allows you to turn the engaged position, an endless printing ribbon selector wheels in a state of partial engagement, causing the slack. According to this first aspect of the invention proposed printing device having at least one endless print belt, provided on its outer peripheral surface with a multitude of characters and secretory type, and passing around the selector wheel and section letters of support, and allows you to select the desired letter of the endless print belt, wherein there is a movable locking element made between the selector wheel and a support section lities, and at the other end of the elastic part with at least one siteplease part, retaining bearing to limit the movement of the rolling retainer due to its adhesion to the elastic part of the rolling retainer, and at least one drive lug on the inner peripheral surface of the endless print belt made with the possibility of engagement with siteplease part of the elastic part of the rolling retainer member, gearing between the driving protrusion and siteplease part when moving the endless print belt causes movement of the rolling retainer to ensure the release of the engagement between the selector wheel and regulatory thickening.

To stabilize the moving action of the rolling retainer printing device may be provided with a retaining guide for the direction of the rolling retainer in the direction of its movement.

The elastic portion may be bifurcated spring part of the engagement. As a forked spring part of the gearing can elastically deform in the lateral direction while moving the movable locking element, for example in the vertical direction is Selena and movable locking element can provide a smooth, elastic movement.

Retaining bearing may have an inclined support surface for supporting the elastic part. Since the elastic portion is elastically deformed along the inclined support surface when moving the movable locking element, the engagement between the driving protrusion of the endless print belt and the elastic section may be further strengthened and movable locking element can provide a smooth, elastic movement.

Endless print belt may have at least one empty partition without letters on its peripheral surface and inner peripheral surface, at least one sign excretory font adjacent to the side of an empty section in the direction of rotation, can be made in the form of a flat section.

In particular, the inner surface of at least one character excretory font adjacent to the side of an empty section in the direction of rotation can be performed without projections that can engage with the selector wheel, thereby preventing engagement between the selector wheel and the endless print belt and allowing it to rotate idle selector wheel.

According to the second aspect of the invention Phra its outer peripheral surface with a multitude of characters and secretory type, and passing around the selector wheel and section letters of support, and allows you to select the desired letter of the endless print belt, characterized in that it comprises the locking element is made between the selector wheel and support section of characters and at least one drive lug on the inner peripheral surface of the endless print belt made with the possibility of engagement with the locking element, and the engagement between the drive plate and the locking element when moving the endless print belt causes the slack of the endless print belt to ensure the idling rotation of the selector wheel.

In the device to prevent contamination of the excretory font in a printing device according to the present invention on a movable stop element is made regulating the thickness and the elastic part, and regulatory thickening made with the possibility of engagement with the selector wheel, and an elastic part with the possibility of elastic deformation. The result may be provided to regulate the operation of selecting the characters of endless printing ribbon (corresponding installation status of individual characters in the support section of characters and between Sousa tape may be desired by turning the selector wheel to rotate the endless print belt, the driving protrusion of the endless print belt is engaged with the elastic part of the rolling retainer just before contact mark excretory font with colorful roller to create a sense resistance (action resistance), causing you to immediately stop the rotation.

If you attempt to rotate the selector wheel at the point of action of the resistance, the elastic portion is elastically deformed and the movable locking element moves slightly in the direction of the section of the support characters.

Thus, the rotational coupling between the regulatory thickening of the rolling retainer and a selector wheel drops below the level of coupling in the normal state of selection of characters, and, in addition, the endless print belt sags from its point of engagement with the selector wheel to the point of engagement with the elastic part of the drive protrusion, thereby weakening its engagement with the selector wheel and allowing the selector wheel to rotate idle.

As a result, excretory font does not rotate and does not come into the region of the colorful clip, can be prevented contamination. In addition, any excessive effort is on the elastic part of the rolling retainer, so it acts in the direction of creating idling rotation between regulatory thickening of the rolling retainer and a selector wheel and does not damage the endless print belt.

As the drive protrusion provided on the inner peripheral surface of the endless print belt and configured to engage with the elastic part of the rolling retainer, it does not reduce the number of characters, and characters excretory font on the peripheral surface of the endless print belt.

According to the second aspect of the invention, the slack is created in the endless print belt when its rotation is prevented by engagement with a locking element, selector wheel and the endless print belt of the trip or in the state in which they are, even if in contact, the rotation of the selector wheel has no effect on the endless print belt, the selector wheel rotates idle, the endless print belt does not move and does not move marks the excretory font farther than the support section of characters, and the possibility of contamination of the excretory font by contact with colourful aliment, the rotary position of which can be adjusted, installed inside the endless print belt can be rotated to position the contact in position without contact with the inner peripheral surface of the endless print belt. In this case, the tension of the endless print belt can be adjusted by turning the Cam member for varying the degree of contact between the Cam element and the endless printing ribbon. More clearly and in detail the essential features of the invention are presented in the PP. 1-15 claims.

At the same time, the rotary pin 11 is sequentially moved to the position corresponding to the selector wheel 5 for entrance into engagement with the inner recesses 5A gearing performed on the inner peripheral surfaces of the selector wheel 5. Thus, the selector wheel 5 desired number can be detected by axial movement of the working shaft 4.

In addition, the frame 3 of the printing device is equipped with indicator 10 mounted for movement along a viewing window 8 parallel to the axis of the working shaft 4. The indicator 10 is connected with the working shaft 4 so that it can rotate only in relation to him and to move together with the working shaft 4 in the axial direction. The indicator 10 is equipped with a pointer 10A, which is included in the viewing window 8. Pointer 10A indicates the selector wheel 5 desired number selected by means of the operating shaft 4.

Each of the endless print belt 7 provided in separate areas of its external peripheral surface of predetermined quantities liter 7A and signs excretory font 7B. In particular, the part of the outer peripheral surface of each endless ink ribbon 7 is equipped with a number of characters 7A and the other half in each border region between group type and group excretory font and as explained below, the empty section 7C facing the observation window 8 and holes 9 access to a paint roller, when the endless print belt 7 is in the final part of its movement.

Part of the inner peripheral surface of the endless ink ribbon 7 opposite liter 7A is made flat, and part of it against characters 7B excretory font equipped with a low drive projections 7D and high drive projections 7E, each of which can engage with the peripheral grooves 5B of the gear selector wheel 5.

High output projections 7E performed on parts of opposite signs 7B excretory font, located essentially in the middle of the characters 7B excretory font. The number of such protrusions may be any selected depending on the number of characters 7A and signs 7B excretory font, etc., and is distributed in a given area of the inner peripheral surface of the endless print belt 7.

If you turn the selector wheel 5, the low drive projections 7D and high output projections 7E engages with peripheral slits 5B gear selector wheel 5 to rotate the endless pechatana roller.

A number of movable locking elements 14 associated with the respective selector wheel 5, mounted on the frame 3 of the printing device between the selector wheel 5 and section 6 letters of support and the inside of the endless printing bands 7, covering the selector wheel 5 and section 6 letters of support.

In particular, the retaining guide 3B which projects from the frame 3 of the printing device, and this retaining guide 3B is in an elongated guide window 14C is made in the Central parts of the movable locking elements 14. Movable locking elements 14 may to some extent be moved in the direction closer or farther from the selector wheel 5.

Each movable locking element 14 provided at one end of the regulating knob 14A to log in engagement with the peripheral notches 5B gear selector wheel 5 and at the other end of the elastic part 14B.

This elastic portion 14B has a forked spring siteplease part 14D. A bifurcated spring saralaya part 14D provided at its end protruding outward siteplease parts 14E. The upper surface saralaya parts 14E is made in the form of inclined surfaces 14F, which are beveled in NAA 15. As shown in Fig. 2, the retaining support 15 is made in one piece with the frame 3 of the printing device. The surface of the retaining support 15 directed towards the movable locking elements 14 form a support for the inclined surfaces 15A, which rest against the inclined surface 14F saralaya parts 14E. Moving the movable locking element 14 is limited by the focus of inclined surfaces 14F in side inclined surface 15A of support.

In the normal position of choice liter movable locking elements 14 are individually spring-loaded in the direction of the selector wheels under the influence of the elastic parts 14B. Between the elongated guide Windows 14C and lock the guide 3B formed in the upper gap S1, so that the movable locking elements 14 can move in the drawings down and back again.

The frame 3 of the printing device provided between the selector wheel 5 and section 6 support liter clamping part 3C, 3D to prevent the deviation of the endless printing bands 7 to the outside. As shown in Fig. 1 and 2, in the normal position of the choice of characters is designed so the printing device the desired number can be selected by movement of the working shaft 4 in the axial direction, poslati clockwise in this series to rotate the endless print belt 7 through the selector wheel 5 and stop the rotation of the working shaft 4 in position, when the desired character 7B excretory font endless print belt 7 will be visible in the viewing window 8.

In this selected position letter 7A corresponding to the mark 7B excretory font installed on partition 6 letters of support and available through the hole 9 of the access to a paint roller. Printing can be done by turning colorful roller R to paint on the letter 7A and cuddling just printing device 1 to the label, for example, by means of a hand lever (not illustrated).

In Fig. 3 shows in section the endless print belt 7 in position when it is rotated clockwise in the drawing in the state to prevent rotation. In this example, the working shaft 4 is brought into rotation for rotation of the selector wheel 5, while the endless print belt 7 is not rotated so that the empty section 7C are opposite the handhole 8 and the hole 9 access to a paint roller, and high drive protrusion 7E endless ink ribbon 7 is engaged with one siteplease part 14E (on the right side of the drawing) of the elastic portion 14B of the rolling retainer 14.

The engagement between the high driving protrusion 7E and siteplease part 14E not Mae who moved the positioning of the characters 7B excretory font endless print belt 7 in the hole 9 of the access to a paint roller and pollution signs 7B excretory font colorful roller R.

In Fig. 4 shows a sectional state of the idling rotation of the selector wheel 5. In the previous state prevent rotation, if an attempt is made to force rotate the selector wheel 5 further, the peripheral cutouts 5B gear selector wheel 5 disengage from the regulating knob 14A of the movable locking elements 14 and pass through it depicts the way.

In particular, the movable locking element 14 is moved downward in the drawing along the retaining rail 3B, resulting in the upper gap S2 between the elongated guide window 14C and the retaining rail 3B, the inclined surface 14A of the elastic part of the slide on the supporting side inclined surfaces 15A, the legs of the forked spring portion 14D of the elastic portion 14B apart on the sides outward, and the engagement between siteplease parts 14E and high driving protrusion 7E endless ink ribbon 7 is amplified.

In this state, the selector wheel rotates idle, as in the endless print belt 7 is formed slack between the part blank section 7C on the upper side and part siteplease part 14E, so that the low drive projections 7D disengage from pereferijnymi and high driving protrusion 7E is in the direction of rotation of the selector wheel 5 and the endless print belt 7 and in addition, the clamping frame 3C and 3D constrain the endless print belt 7 and not allow it to bend outward, the amount of slack formed between the selector wheel 5 and the endless ink ribbon 7 is sufficient to cause idle rotation of the selector wheel 5.

Thus, the selector wheel 5 can rotate idle at Annex excessive external forces. Moreover, as the rotation of the selector wheel 5 acts more on regulatory thickening 14A movable locking element 14 than the endless print belt 7, there are no obstacles to select letters due to wear of the rolling retainer 14 as the movable locking element 14 is stronger than the endless print belt 7.

If the selector wheel rotate in the opposite direction (counterclockwise), the engagement between the peripheral slits 5B engagement and regulatory Cams 14A is restored and the elasticity of the movable locking element 14 returns to its original position according to Fig. 1.

In Fig. 5 and 6 shown in the cross section of the double printing device according to the second aspect of the invention.

In Fig. 6 a is ist 21, having essentially the same design. Parts similar to the parts of the printing device 1, is indicated on the drawings similar positions and will not be explained in detail. Will be explained only constructive characteristics different from the characteristics of the printing device 1.

The first clamping frame 23A and the second clamping frame 23B of the frame 23 of the printing device 20 is made essentially symmetrically in the lateral direction and in between them is provided by the guide plate 24, whereby ensures smooth movement of the endless printing belts 7.

In the frame 23 of the printing device is installed sleeve 25 with the possibility of rotation around their axes. The selector wheel 5 rely on the sleeve 25 and the operating shaft 4 passes through the sleeve 25. The sleeve 25 is provided in the axial direction of the slits 25A (Fig. 6). The pivots 11, mounted on the working shaft 4 which is inserted in the slit 25A and the top swivel pin 11 engages with the inner slots 5A gearing selected selector wheel 5.

On the other hand, the operating shaft 4 is installed in accordance with the rotating together with the safety rods 26 designed to provide rotation system-easy installation shall provide a work shaft 4 to rotate only in parallel and only together with the working shaft. It is mounted for movement relative to the frame 23 of the printing device only in the axial direction and is engaged with a single peripheral notch 5B of the engagement of each of the United selector wheel 5. The safety rod 26 has a recess 26A, aimed in the direction of the swivel pin 11 to ensure rotation of the selector wheel 5 which engages with a rotary pin 11.

Thus, because only one of the selector wheel 5, is selected using the input shaft 4 can rotate and peripheral notches 5B engagement of the other of the selector wheels are in engagement with the rotating together with the shaft safety rod 26, the selector wheel 5, which is adjacent to the selected selector wheel 5, which rotates, is prevented from rotation, so that none of the endless print belt 7, in addition to selected and involved endless print belt, not moving.

In Fig. 7 shows in side view an endless print belt 7. The low number of drive lugs 70 formed on the inner peripheral surface of the endless ink ribbon 7 two less than in the case of the printing device 1 (Fig. 1).

the m sections 7C in the direction of rotation of the endless ink ribbon 7, not have a low drive projections 7D, and in the form of flat parts 7F.

Although the following example shows two flat parts 7F on the inner peripheral surface of the endless print belt 7, but from the point of view of preserving the possibility of bringing in rotational movement of the endless print belt 7 through the selector wheel 5, it is possible to further simplify the occurrence of idling rotation to provide the inner peripheral surface of the endless ink ribbon 7 two sets adjacent to each other flat parts 7F (all four).

As double printing device 20 of this design provides the same effects as the printing device according to Fig. 1 and others, it can reliably prevent contamination of the urinary font 7B colorful roller R without damage to the endless print belt 7.

In particular, as shown in Fig. 8, if you take the printing device 21 to the right, as an example, when high drive protrusion 7E endless ink ribbon 7 is engaged with one of saralaya parts 14E movable locking elements 14 due to rotation of the selector wheel 5 in the example is the same rotation).

If the selector wheel 5 of the printing device 21 in the right part of Fig. 8 turn clockwise in an attempt to continue the clockwise rotation from the state of rotation, the selector wheel 5 passes through the regulating knob 14A and enters a state of slipping because of the external peripheral surface of the selector wheel 5 in the direction of rotation from the inner peripheral surface of the endless print belt 7, which includes the flat part 7F (without drive lugs). In other words, as clearly shown in the drawings, the endless print belt 7 assumes a position of weakness relative to the selector wheel 5, resulting in idle rotation.

In more detail, since the inner peripheral surface of the excretory font 7B directly to the right in the drawing from an empty section 7C, located in the viewing window 8 is a flat part 7F, no low drive protrusion 7D, the engagement between the selector wheel 5 and the endless ink ribbon 7 are missing, resulting in slack in the endless print belt 7, which provides an easy transition to the state idle rotation.

Similarly, the printer according to the second aspect of the invention described above, the printing device according to the first aspect of the invention according to Fig. 1-4 may also be of a design, leading to the formation of slack of the endless print belt 7 for shifting the selector wheel 5 in the state of idling rotation.

If the diameter of the selector wheels according to the first aspect of the invention to make it smaller than the diameter of the selector wheels according to the second, the formation of slack of the endless ink ribbon 7 and the transition of the selector wheels in the state of idling rotation may be provided by the choice of height low drive projections 7D in positions corresponding to the flat portions 7F, within a specified area.

In addition, if the selector wheel 5 have a larger diameter than the diameter according to the second aspect of the invention (Fig. 5), the idling rotation occurs if the flat part 7F formed on the inner peripheral surface of the endless printing bands 7, form the equivalent of two characters to the left and to the right of the empty sections 7C.

In Fig. 9 and 10 shows a sectional printing device according to a third aspect of the invention. the x tape 7 between the retaining support 15 and section b of support letters. The mechanism 30 of the tension control has a controller 31 (Cam). As shown in Fig. 11, the controller 31 is made as a single unit and includes having a cross section in the shape of the ellipse main body 31A, the rotary shaft 31B of the control Cam and the adjustment lever 31C and exciting protrusion 31D.

In particular, the ellipticity of the main body 31A provided on both opposite ends of the rotary shafts 31B of the control Cam. The ellipticity of the main building rests rotatably on the frame 3 of the printing device using the rotary shafts 31B of the control Cam. During the rotation of the elliptical main body 31 of its outer peripheral part is fixed in and out of contact with the inner peripheral surfaces of the endless printing belts 7.

One end surface of the elliptical main body 31A provided with an adjusting lever 31C extending perpendicular to the rotary shaft 31B of the control Cam, and on the upper part of the adjusting lever 31C has a gripping protrusion 31D, directed towards the frame 3 of the printing device.

On the other hand, as shown in Fig. 12, the frame surface 3 of the printing device, located perpen is lackow, interacts with exciting protrusion 31D. Other elements are the same as shown in Fig. 1 and 2.

During Assembly of the printing device on the manufacturer, the position of the ellipticity of the main body 31A relative to the endless printing ribbon 7 can be adjusted by means of rotation of the main body 31A around the rotary shaft 31B of the control Cams for bringing exciting protrusion 31D adjustment lever 31C in the interaction with the desired from the slots 32 of the adjustment Cam frame 3 of the printing device.

As shown in Fig. 9, for example, the tension of the endless print belt 7 can be increased by the location of the ellipticity of the main body 31A with opisaniem in the endless print belt 7, because it leads to the fact that the ellipticity of the main body 31A relatively strongly attached to the inner peripheral surfaces of the endless printing belts 7.

On the other hand, if the ellipticity of the main body 31A is turned to the position shown in Fig. 13 and 14, the controller 31 does not contact with the inner peripheral surfaces of the endless printing bands 7, resulting in the tension of the endless printing ribbon 7 can be reduced by echnik print tape 7 to ensure proper rotation and, in addition, it provides conditions for weakening the endless printing belts 7 in the state of idling rotation, shown in Fig. 14, and the effect of idling rotation of the selector wheel 5, is associated with a state of slack, by moving to the specified region.

Thus, the set angular position of the knob 31 can be changed to regulate the tension of the endless printing belts 7 in response to stretching or weakening of the endless printing belts 7 during use of the printing device.

Since, as indicated above, the invention provides for the locking elements, each of which has regulatory thickening and an elastic part, and, in addition, provides for retaining bearing, which rests against the elastic portion to limit movement of the movable locking elements, this selector allows the wheels to slip and rotate idle, thereby preventing contamination of the endless printing belts 7 colorful cushion and reducing the load on the endless printing belt 7.

In addition, because the attempted rotation of the selector wheel for preventing rotation causes it to idle rotation by separating the external the spine of the endless print belt, it does not occur load due to contact friction between the two surfaces.

In addition, if a mechanism of tension within the endless printing bands, the degree of tension of the endless print belt can be adjusted in a simple way by turning the regulator within a specified area.
