The invention relates to metallurgical production, in particular to the field of production of billets, and can be used in the complex of the equipment for forming a stack of billets, which shall be binding and sending to the warehouse.

Known stacking device according to the patent of Ukraine # 44568 And, B65G 57/18, comprising a slide mounted in a vertical guide frame for movement from a drive, with which the articulated slider and copiers, attached to the side surfaces of the frame, symmetrically relative to the vertical axis. In addition, the device also includes levers, each of which is pivotally attached to the slider at one end and a second end equipped with a video posted with the possibility of contact with the corresponding copier. The lever has a supporting inserts with horizontal platforms that are attached can reinstall. Insert is made with curved surfaces and are installed in the Central notch of the slide. The device is fitted with a set of inserts to ensure kantowski variety of different sizes of cross-sections.

Does stacking device as follows.

The rollers of the roller conveyor to transport a series of four blanks, centered about the axis of the roller conveyor, and stopping the pad from sliding is try it on the axis of the device for forming stacks. Before you begin to work from a set of inserts with curved surfaces choose the one that matches the cross-section billets, subject to tipping, and put the anchor insertion levers so that each one overlaps the center of mass at the workpiece. Then include the actuator and the slider is moved in the vertical rails of the frame, and the rollers roll levers on the vertical parts of the copier and the reference horizontal surface inserts levers after contact with the lower surfaces of extreme blanks raise them. Upon further lifting of the slide at the workpiece placed on the support surfaces of the inserts levers, rise to a height, which is calculated by the expression given in the formula. Upon further lifting of the slide, when the rollers on the levers roll on curved sections of the copier, and the levers are rotated in the hinge points of attachments to the slider, horizontal reference insert depart from the extreme blanks, and in contact with them come the curvilinear sections of the inserts. As a result of further lifting of the slide at the workpiece is moved along a curved trajectories and placed on two medium-sized workpieces lying on the rollers of the roller conveyor with the formation of stacks of four blanks, arranged in two rows. Reverse p is the water, the device returns to its original position, and formed a pile of blanks is strapped and then the roller is transported, for example, a warehouse.

It should be noted that when working with a large number of sizes of cross-sections varieties stacking device equipped with several inserts, their number is determined by the number of sizes of stackable workpieces, resulting in higher capital costs associated with the manufacture and operation of the stacking device.

Know another stacking device according to the patent of Ukraine №6350U, B65G 57/18, 16.05.2005 closer to the claimed solution and adopted as a prototype.

It consists of a frame with two sides, the axis of which is placed at an angle copiers installed with the ability to reinstall from own funds move; insert made of a composite of two parts. Each of the insert, mounted at an angle on the slider with the ability to change the position from the individual the means to move. To each side of the insert are articulated on the lever, carrying the horizontal support platform, with a roller at the free end. The slide is placed along the axis of the device and coupled to drive its vertical movement. In the stacking device and part of the insert, and copiers are installed at the same angle, and means for moving the parts of the insert and copiers you Olney in the form of a pair of screw-nut.

Does stacking device as follows.

Initially, each component of the insert and each copier own means to move set in position, depending on the sizes of cross-sections of billets, subject to tipping. After you configure the elements of the device drive motion of the slide is lowered to the position in which the horizontal platform levers inserts are below the level of the rollers of the roller conveyor, the rollers of the arms in contact with the vertical parts of the copier.

After the delivery rollers of the roller conveyor and stops along the axis of the stacking device of a row of four of billets include the drive of the slide, which moves the slider with inserts to contact the horizontal support platforms levers with the lower surfaces of extreme blanks. Further movement of the slide is accompanied by a vertical rise of extreme blanks due to the h value. After lifting the extreme blanks on the value of h and making videos of the levers moves the value h on the vertical portion of the Cam moves the roller levers on curved sections of the copier under the influence of the drive movement of the slide and rotation of the arms at the points of their hinge joining the parts of the inserts. The horizontal sections of the levers away from the bottom of the surfaces of the workpieces, and a curved side inserts come in contact with them, and then under the influence of the efforts of the drive movement of the slide at the workpiece moving along a curved trajectories, are placed on two medium-sized workpieces with the formation of the pile, after which tying is transported by the rollers of the roller conveyor in the direction of the process stream.

Compared to similar capital costs associated with the manufacture and operation of the stacking device is lower due to the exclusion of the set of inserts for different sizes of cross-sections of the blanks.

However, it should be noted that the device stacking blanks in addition to the drive of the slide four of funds for travel, which are used for pre-operational settings of the copier, the horizontal support platforms levers and parts insert, complicates the design of the whole mechanism and simultaneously reduces its reliability.

Due to the fact that the stacking device of billets equipped with racks arranged symmetrically relative to the vertical axis of the device on the frame with the possibility of relative horizontal movement of the actuator and the support crossmember installed along the axis of the device and coupled to the actuator move, and also due to the implementation of the RAM composite of two parts and relations of the horizontal surfaces of the frame and horizontal surfaces of the uprights, horizontal surfaces of each part of the slide and horizontal surfaces of the reference beam, the vertical surfaces of the uprights and vertical surfaces of each part of the slide through the connection groove-protrusion", and by attaching to the vertical surfaces of each rack and copiers pivotally attaching to each part of the slide levers with g the horizontal support surfaces and rollers at the free ends, it became possible to move the unit at specified distances both vertically (due to the actuator to move the support beam)and two horizontal sides (from the actuator moving the racks at the heart of any implementation as a single screw shaft, in the form of a separate screw shafts, in the form of a hydraulic actuator), adjusting thus the stacking device on the casting-off of varieties in a wide range of sizes of cross-sections of workpieces using fewer tools to move, for example, two mover instead of five, as in the prototype.

By performing on the horizontal surface of the reference beam in the Central part of the sample, the depth of which is not less than the depth of the above-mentioned groove, it has become possible to simultaneously and seamlessly move horizontally toward each other the two parts of the slider when adjusting the width of billets and free removal of scale falling from the heated billets.

Thanks to the connection groove-protrusion is T-shaped or in the form of a "dovetail" became possible, keeping the connection elements, to perform a fixed displacement node device when reconfiguring for stacking of billets with different sizes of cross-sections without additional components, that when the result in simplification of the structure of the stacking device and improving its reliability.

All of the above has helped reduce the number of nodes you want to move elements of the stacking device during the migration process for the preparation of stacking variety of other sizes of cross-sections and when the device, which leads to simplification of its design while improving the reliability of the device.

The exception to the above combination of distinctive features of at least one does not achieve a technical result.

On horizontal surfaces of the frame 1, on horizontal and vertical surfaces of each of the component parts of the slide 7 is made ledges, and on the respective horizontal and vertical surfaces of the uprights 2 and the horizontal surfaces of the reference beam 5 is made return them to the slots. In this case, the grooves and the protrusions are made of T-shaped form. The tabs in addition to these forms may take the form of a "dovetail", cylindrical or any other shape that provides constant contact connected elements and the possibility of their fixed displacement without the use of additional funds. The form of the protrusions is determined by the technological possibilities of the manufacturer of the stacking device. On the Central part of the horizontal surface of the reference beam 5 is made sample "H", the depth of which is not less than the depth of grooves located on it. The depth of the sample "N" is selected from the condition allow moving parts slide 7 when filling the above-mentioned sampling scale falling from the heated billet billets.

To each part of the slide 7 are articulated on the lever 8 with the roller 9 mounted on its free end and placed interoperable with the corresponding copier 3. The levers 8 are horizontal platform. In each rack 2 is asesino, at least one retaining device 10. In this case, the retainer 10 is made in the form of a screw placed in the corresponding hole of the rack 2 with the possibility of fixation with respect to the frame 1. Form of the locking device for solving the tasks essential does not matter and may be different from the accepted, may be, for example, staples or any other.

The actuator 4 move 2 racks situated on the side opposite to the placement of the locking device 10. In this case, the actuator 4 is made uniform for both racks 2 and presented in the form of a General screw shaft 11 to the drive end. The shaft 11 has on opposite sides of the sections with right and left threads placed in the proper holes of the uprights 2, and the collar 12 mounted in the support 13 attached to the frame 1 from its drive end. (see Fig.1-6). The presence of the collar 12, is placed in the sample support 13, prevents axial displacement of the screw shaft 11 when moving racks 2.

Rotation of the screw shaft 11 may be performed by either an electric or manually.

You can also move each of the racks to carry out manually with subsequent fixation of their provisions.

Before operation set the device nodes in provisions for stacking the set of billets. Depending on the dimensions of the cross sections, grades, subject to the packaging, move the rack 2 with the parts of the slide 7 horizontally relative to the frame 1 and stop at the position at which between the vertical surfaces of the "L" parts of the slide 7 will set the size to allow two of billets placed along the axis of the device, with the technological gap. For this release the rack 2 from the stoppers 10, the actuator 4 to move them to a specified size and retaining devices 10 fix them in a predetermined position. what about moving the horizontal grooves of the uprights 2 are mixed up on the appropriate tabs of the frame 1. Due to the presence on the shaft 11 sections with right and left threads, racks 2 are moved towards each other, doing the same course. Then include the actuator 6 and move the supporting yoke 5 to the lowest position. While the rollers 9 each lever 8 roll on respective vertical surfaces copiers 3, a horizontal platform mounted below the rollers of the roller conveyor. Next, the conveyor moves the package of four blanks arranged in a row, centered about the axis of the rollers of the roller conveyor, and stop along the axis of the stacking device.

After contact of the horizontal surfaces of the levers 8 with the lower parts of the two extreme blanks further rise of the nodes of the device is accompanied by the rise of extreme blanks on the value of h, which is determined by the expression:

wherea - height billets,

f - coefficient of friction between cantemos and stationary workpiece,

fkthe coefficient of friction between the curved surface of the slide and cantemos for what towkay,

α - the angle between the tangent to the curved surface of the slide at the point of contact with the workpiece and the horizontal plane.

After lifting the extreme blanks on the value of h vertical rise still further component parts of the slide moves the rollers 9 of the levers 8 on sloping plots copiers 3. The result that the lever 8 is rotated in the points of its hinge connection to an integral part of the slider 7, the horizontal platform of the levers 8 are discharged from the surfaces of extreme blanks, and a curved surface "M" pieces of the sliders come in contact with extreme blanks. And the further rise of parts of the slide at the workpiece moving along a curved trajectories, are installed on the middle two blanks, forming a stack of four pieces. As a result of further lifting of parts of the slide 7, the entire stack is lowered into the pocket formed by the surfaces of the "L" and "To" parts of the slide 7, and weighed over the rollers of the roller conveyor. A stack of four blanks lying on the surface "To"tie. Next return stroke of the actuator 6 of the lower part of the slide 7 along with a package of blanks and post it on the rollers of the roller conveyor, with parts of the slide 7 with the levers 8 are omitted in the lower starting position and horizontal surfaces of the levers 8 are located below the level of the roller the roller table. Then the rollers of the roller conveyor is transported bound stack of four blanks next in the direction of the process stream.

When changing assortment of blanks to be stacked, the device adjusts the same way as described above.
