Description

# Vfe / - v

The invention relates to light industry and can be used to set buttons on the product.

A device for fastening accessories on leather goods is known, comprising a housing, a bracket with a stand and a matrix, an impact mechanism with pliers, a mechanism for supplying parts, a locking unit and an actuator including a power cylinder for a working stroke and a lever associated with the impact mechanism.

A device for fastening buttons on a product is also known, comprising a matrix mounted on a bed, a punch with jaws, feeders with cutters, a button element supply unit including a housing with channels for button elements and their pushers.

However, with the help of these devices only one part of the button can be attached to the top or bottom, and in order to fix the other part of the button, it is necessary to change the working elements or use a second device, which reduces the operational capabilities of the devices.

The purpose of the invention is to expand its operational capabilities.

This goal is achieved by that. that in a device for attaching buttons to a product comprising a matrix mounted on a bed, a punch, feeders with cut-offs, a button element supply unit including a housing with channels for button elements and their pushers, it is new that it is equipped with two electromagnets , a two-arm lever, two leaf springs, each of which is associated with the corresponding core of the electromagnet and the end of the two-arm lever, located between the electromagnets and located along the longitudinal axis of the two-arm lever a spring connected to the indicated end of the two shoulders of the lever and the bed, while one of the separators is made with two channels and connected to the free end of the two shoulders of the lever with the possibility of movement in the horizontal plane and alternately aligning its channels with the channels for the button elements.

Figure 1 shows a General view of the device; figure 2 - head; in Fig.Z - feeder; figure 4 is a view a in figure 3; Fig. 5 shows a cutter assembly for a ball and a block; on ig.6 - section BB in Fig.5; 7 is a button; on Fig - scheme of operation of the cutter, 8a, b, c, d, d - the ball feed cycle, 8th, g, s, and - the block feed cycle.

The device comprises a frame 1, on which a matrix 2, a punch 3, are mounted

feeder 4 with shutoff 5 for ball and block, feeder b with shutter 7 for gear, feed unit 8 of button elements, including housing 9 with channels

10.11 for pushers 12.13 and channels 14.15 for button elements. The device is equipped with two electromagnets 16.17, a two-arm lever 18, two leaf springs 19, each of which is connected with the respective cores 20 of the electromagnets 16.17 and the end of the two-arm lever 18 located between the electromagnets 16.17 and located along the longitudinal axis of the two-arm lever 18 a return spring 21 connected to the specified end of the two shoulders of the lever 18 and the frame 1. The cutter 5 is made with two channels 22,23 and is connected with the free end of the two shoulders of the lever 18

horizontal plane and alternately aligning its channels 22.23 with channel 14 for button elements.

The cutter 7 has one channel 24. The pushers 12,13 are driven

from the pneumatic cylinder 25. Feeder 4 includes two vibro drives with removable bowls 26.27 and a tray 28 with two channels 29 and 30. Feeder 6 includes a vibro drive with a bowl 31 and a tray 32.

The device comprises a working stroke cylinder 33, a system of levers 34 and a guard 35. The hand guard 35 includes a pneumatic cylinder 36, on the rod of which a frame 37 with a guard 38 is fixed. The device has pneumatic equipment 39 and a control unit 40. The matrix 2 is equipped with stops 41 for laying the product. The punch 3 has jaws 42. The device is equipped with throttles 43 and 44 for supplying compressed air

and electric pedal 45.

The device operates as follows.

Button elements are loaded into bowls 26.27 and 31 (balls are placed in bowl 26, step blocks are in bowl 27, toothed rings are in bowl 31), and vibro drives are turned on. In the bowls, the button elements are oriented in a predetermined position and fill the channels of the trays. When you press the electric pedal 44,

the hand guard 35 slides down.

On the matrix 2 on the stops 4. the product is stacked. If the guard 38 of the arms 35 encounters an obstacle (operator's fingers) on its way, the pneumatic cylinder 33 of the stroke does not turn on. If the guard 38 makes a full stroke, the pneumatic cylinder 33 of the working stroke is turned on and the punch 3 with jaws 42, which

serve and rivet the elements (ball or block) on the product

After the punch 3 with the jaws 42 has returned to its original position, the electromagnets 16 and 17 are turned on, under the influence of which the lever 18 rotates and moves the cutter 5 in the horizontal plane to the left or to the right according to the specified program. The channel 22 or 23 of the separator 5 is aligned with the channel 14 of the feed unit 8 of the button elements.

At the same time, under the influence of the magnet, the cutter 7 is shifted from its initial position, its channel 24 is aligned with the channel 11 of the feed unit 8 of the button elements.

Then, through the chokes 43 and 44, the button elements are fed into the channels 10 and 11 by compressed air. Pushers 12,13, driven by the pneumatic cylinder 25, direct the button elements through these channels to the punch 3 with jaws 42 and the matrix 2.

Since the width of the cutter 5 is equal to the diameter of the button element (ball or block), when the cutter 5 moves left or right, only one button element is cut off from the tray 28, which is supplied by compressed air to the channel 14 of the supply unit 8.

The program for supplying the button elements is embedded in the electronic control unit 40 in such a way that three options are possible: the first is that the cutter 5 moves from the initial position only to the left and only balls are fed into the channel 14; the second - the cutter 5 moves from the initial position only to the right and only blocks are fed into the channel 14, the third - the cutter moves from the initial position to the left, then to the right, and then balls or blocks are alternately fed into the channel 14. The program is implemented by dialing the numbers corresponding to the number of blocks and balls to be placed on the product. A set of numbers is produced by the toggle switches of two counters located on the control panel of the control unit 40.

After finishing the movement of the cutter 5 left or right, it returns to its initial position from the return spring 21 and the flat springs 19. The location of the springs 21 and 19 allows you to quickly dampen the vibrations, holding the cutter 5 in its original position after each movement. The gap between the cores 20 of the magnets 16 and 17 and the lever 18 is set equal to half the travel of the cores 20, which makes it possible to control the movement of the cutter 5 ' about a predetermined program independently of each of the magnets 16, 17.

Subsequently, the cycle repeats.
