The invention relates to the automation of technological processes and is intended for the orientation of piece goods, mainly thin disks, to boot-up devices of automatic machines.

A device for feeding and orienting a snatch is known, comprising a conveyor with grippers and an inclined chute located at the exit of the hopper to the hopper for orienting the covers. The bunker is equipped with a plate, one end of which is rigidly connected to the bottom, and the other end is spring-loaded and has the shape of a corner. The bottom side of the corner is parallel to the grippers so that it contacts with them in the process of moving the conveyor ij

However, this device has low productivity due to the location of the conveyor in the bunker and its structure is unreliable in operation due to the large efforts that occur when the conveyor hooks interact on the underside of the corner, which leads to significant dynamic loads in the capture zone of the covers, impairs their orientation and lowers device performance. In addition, this device does not allow work with parts such as metal stamped discs due to their ability to stack with a foot. Parts do not catch the conveyor and they do not completely fill it.

It is also known a device for oriented feeding of disc-shaped products, comprising a feed hopper mounted on a frame, an inclined conveyor with a hook, installed at the exit of the hopper and a device for returning non-oriented disks. An outlet hole is formed in the lower part of the bunker, with a valve under which the guide tray is fixed.

However, the known device also does not allow to work reliably with thin metal disks of large diameter (for example, a disk diameter of 250-300 mm with a thickness of 1-5 mm): due to their ability to stack with a foot and poorly sliding them onto the conveyor, as a result the course of the conveyor and it is also not fully filled. 0t436542

here the unreliability of the device and its performance is low.

The purpose of the invention is to increase the reliability of the device. S The goal is achieved by the fact that in a device for oriented feeding of disc-shaped products, containing a bunker mounted on a frame with a valve, an inclined 10 conveyor and a guide tray located between them, a pusher with an arcuate working surface 15 is installed under the bin of the bunker at the entrance section of the guide tray. and driven by a power cylinder,

at the same time, the pusher is fixed on the rod of the power cylinder and on its base plate on the frame - articulated.

Fig. 1 shows a device 0 for oriented feeding of disc-shaped products, ob1O1y type; Fig.2dno feeder adjacent to the conveyor belt; on fig.Z - feeder pusher.

5 Device for oriented

feeding disc-shaped products contains a cool conveyor belt 1 with bias, - mounted on the bed 2, the hopper 3,

0 having an axis 4 swing. The swing axle bearings are mounted on brackets 3 mounted on two side racks 6 mounted on frame 2. The hopper is rotated by pneumatic syndrome 7. The slot size in the bottom of the hopper is adjusted by the gate 8 and one of the gate 9 or 10 (depending on the size of the workpiece) . Under the hopper

0 3 there is a feeder 11, and in the lower part of it there is provided a pusher 12 with an arcuate-shaped working surface. The pusher 12 has the ability to rotate around the axis 13,

5, thereby changing the position of the disc-shaped products so that they lie flat on the conveyor belt. The actuator of the pusher 12 is, for example, an air cylinder.

O 14, which simultaneously performs 4 oz of non-rigid in the event of a large number of discs between the wall of the pusher 12 and the conveyor belt 15.

S At the bottom of the feeder 11 is provided for the right of km. tray, made in the form of the following bottom 16, kOTopoe structurally fixed

on the same axis as the lower edge of the pusher 12. Due to the spring 17, it is pressed by the rollers 18 to the conveyor belt 15, which ensures the gaplessness between the bottom of the feeder and the conveyor belt.

The device has a tray 19 for disc-shaped products 20 mounted on a rack 6 on axles x 2j. On the stationary part of the conveyor, at the exit of the feeder, there is a cut-off device that allows only one disc to pass (not shown

The device works as follows.

The pallet 19 with the disks 20 is mounted on the rack 6. Using a pneumatic actuator (not shown), the pallet is rotated around the axis 21 to the required angle DO1 to allow some of the disks to fall into the hopper 3. To empty the disks from the hopper 3, the hopper automatically cycles through the pneumatic cylinder 7 with a blow to the stops in the moves.

Shibers 8 and 9 or 8 and 10 form a slot in the bottom of the bunker, the amount I drop depends on the size of the barrel. drive for each oscillation. Na436544

The presence of the pusher 12 permits the reorientation of the discs that have fallen into the feeder 11. The pneumatic cylinder 14 is not only the actuator of the pusher 12, but also the compensator in case of a large number of discs between the working surface of the pusher and the conveyor belt. The pusher 12 may have a spring

10 compensator (fig.Z). In this case, the plunger moves any actuator, and consists of two movable parts 22 and 23, interconnected by a spring 24. The backlash between

15 The DNYA4 feeder and the moving belt of the conveyor are provided with the following bottom 16.

An alternate arrangement is provided with the present invention.

The flow of discs from the hopper into the feeder in small batches eliminates the possibility of jamming, and the presence of the pusher in the feeder makes it possible to reliably stack the discs on the conveyor belt with a plane.

The expected economic effect from the maximum amount of use will be 100 thousand rubles, including 30 thousand rubles for the industry.
