Abstract

The invention relates to the manufacture of electronic products and relates to technological equipment for single-piece feeding from the foot flat products, mainly glass plates of sound guides. The purpose of the invention, the expansion of operational capabilities, is achieved due to the fact that the products 15 are each individually supplied from a foot 6 placed in a shop mounted on the body 1 of the device. At the same time, the device contains a movable base 3 for supporting the foot 6, a pusher 4 with a drive for its movement. The store has guides 8 with a slider 9 of a movable base, spring-loaded to the end of the bottom wall 11 of the store and a separator 12. On the side wall of the store there is a holder in the form of a pawl 16 with a spring 21. The pusher 4 interacts with a periodic clamping lever 17, mounted on the housing 1 of the device. The step-by-step movement of the slider 9 with the base 3 and the separator 12 is as follows: the slider 9 with the base 3 rigidly fixed on it and the separator 12 from the drive device 19 performs a reciprocating motion, first with the foot of parts sandwiched between the pusher 4 and the base 3, on the thickness of the loaded parts 15, and then when the pusher 4 is locked, only with the base 3 and the separator 12 without a stack of parts by the amount of a certain gap. After ejection of the part 15 into the receiver, the device 19 moves away from the stop 20 of the slider 9 and the slider returns to its original position under the action of the spring 22. 5 il.

Description

and a separator 12. On the side wall of the store there is a holder for products in the form of a dog 16 with a spring 21. The pusher 4 interacts with a clamp periodically locking it in the form of a lever 17 mounted on the device body 1. Step-by-step movement of the slide 9 with the base 3 and the separator 12 is as follows: the slide 9 with the base 3 rigidly fixed on it and the separator 12 from the drive device 19 performs a reciprocating

first moving along with the foot of the parts sandwiched between the pusher 4 and the base 3 for the thickness of the loaded part 15, and then with the pusher 4 locked with only the base 3 and the separator 12 without the foot of the parts for the amount of a certain gap. After ejection of the part 15 into the receiver, the device 19 moves away from the stop 20 of the slider 9 and the slider returns to its original position under the action of the spring 22. 5 il.

The invention relates to the manufacture of electronic products and relates to technological equipment for single-piece feeding of flat products, mainly glass sound plates, from the stack.

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

FIG. 1 shows a device as viewed in FIG. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a section B-B in FIG. 2; in fig. 5 - downloadable part.

The device for single-piece feeding from the foot of flat products comprises a housing 1, a prism magazine 2, a movable base 3 for supporting the article foot, a pusher 4 driven by a load 5 for pressing the foot 6 of products against the base 3 and a slam-shutter 7 in the form of a gate. The magazine 2 is made with guides 8 and a slider 9 with a drive for moving it, while the movable base 3 is spring-loaded to the end 10 of the bottom wall 11 of the magazine. On the slider 9 is installed the separator 12 in the form of a wire spring with a bent pointed end 13. The side wall 14 of the store 2 is provided with a holder of the part 15 in the form of a spring-loaded pawl 16. The pusher 4 is equipped with a clamp in the form of a lever 17 mounted on an axis 18 attached to the device 1 . The drive device 19 of the slide 9 is adapted to cooperate with its stop 20. The dog 16 is spring loaded by means of springs 21. The device also includes a return spring 22 installed between the guide 8 and the stop 20 of the slide 9 and intended to move the slide to its initial state. The cutter 7 of the gate mounted on the lever 23 with the ability to interact with the drive element 24. The lever 17 clamping the pusher 4 is designed to interact with the drive element 25. The drive of the pusher 4 in the form

cargo 5 is arranged to interact with it by means of a cable 26 and a roller 27. Each piece is issued to the receiver 28.

The device works as follows.

In the initial position, the pusher 4 is locked in the magazine 2 by the lever 17 and does not affect the movement of the foot

6 products. In this case, the part 15 is held in the foot by the dog 16, the base 3 is retracted from the product being pushed out by an amount of gap a (Fig. 2) sufficient to separate the product from the foot using the separator 12.

Next, the drive element 24 acts on the lever 23 of the gate 7, which moves separated from the foot of the details of the upper part 15 and delivers it to the receiver 28. The gate 7 moves to its original position. Driving gear

the device 19 moves away from the stop 20 of the slide 9 and the spring 22 sends the base 3 up to the stop of the slide 9 at the end 10 of the bottom wall 11 of the magazine 2. The base 3 comes close to the end plane of the part

15, and the pointed end 13 of the separator 12 enters the part 15. The lever 17 under the action of the drive element 24 moves away from the pusher 4, which creates pressure on the foot 6 under the action of the load 5 in the direction of the movable base 3. Then the drive device 19 is turned on and compressing the spring 22 in the direction of the receiver 28, moves the slider 9 with the base 3, the separator 12, the foot of the 6 products, the pusher 4 by the thickness of one piece 15. After that, the base 3 stops, and the next part 15 is under the dog 16. 25 ementa lever 17 clamps

0 pusher 4 in magazine 2, removing the effect of load 5 on foot 6 Under the action of the actuator 19, the base 3 with the slider 9 moves away from the upper product together with the separator 12 by the amount of gap, a section with a pointed end 13

another part from the foot 6. Then the upper part is moved by the gate to the receiver 28. Then the process is repeated in the same sequence.
