Abstract

The invention is intended for transferring piece goods from a conveyor to a conveyor and improves reliability of operation. The pusher includes guides (H) 9, 10, on which the coupled carriages (K) 7, 8 are movably mounted. The latter are connected to the power cylinder 1. At K 7, 8, there are gates that have a turning mechanism with a helical groove connection - finger. Counter balances are provided for holding the sliders in the turned position. The rotation mechanism is made in the form of cross-arms (T) 17, 18 installed at the ends of H 9, 10 with the ability to move along the latter and interact with K 7, 8 through stops 5, 6 connecting their cheeks 3, 4. Fingers 19-22 are fixed on T 17, 18, and the grooves 13-16 are made on H 9, 10 mounted in bearings 23. In the initial position K 7, 8 with tongs are in the leftmost position. When approaching the goods on the conveyor to the place of collision. g (L

Cylinder 1 is turned on and K 7, 8 is moved with gate valves that push the load off the conveyor. At the end of the collision, K 7, 8 through abutments 6 abut against T 18. Lastly, moving along H 9, 10, with their fingers 20, 22, it acts on grooves 14, 16. As a result, H 9 with a gate will turn clockwise, and H 10 with a gate - counterclockwise. When switching cylinder 1, the gates in the rotated position return to their original position. When the cheeks 3 interact, through the stops 5 on the T 17, the latter will move to H 9, 10. When the fingers 19, 21 interact with the slots 13, 15, the H 9 with the gate will turn counter-clockwise, and the H 10 with the gate will turn clockwise. Shibera back to its original position for pushing goods from the conveyor. 7 il.

This invention relates to mechanisms used to transfer piece goods from a conveyor to a conveyor.

The aim of the invention is to improve the reliability of the device.

FIG. 1 shows the proposed jogger, top view; in fig. 2 - the same, side view; in fig. 3 - pusher, top view, with a notch; in fig. 4 shows section A-A in FIG. 3, with gates in working position; in fig. 5 - the same, with gates in the off position; in fig. 6 is a section BB in FIG. 3; in fig. 7 is a section bb of FIG. 3

The pusher contains a power cylinder (pneumatic cylinder) 1, a rod, 2 of which is attached to the sh, axes 3 and 4, having stops 5 and 6 (Fig. 3). Between the cheeks 3 and 4, the carriages 7 and 8 are freely located, moving along the guides 9 and 10. K. The carriage 7 is attached to the gate 11, and to the carriage 8 - to the gate 12. The guide 9 is provided with the front 13 and rear 14 left spiral grooves, and guide 10 is provided with front 15 and rear 16 right spiral grooves. The rails 17 and 18 with fingers 19, 20 and 21, 22 are placed on guides 9 and 10. The traverses 17 and 18 with fingers 19-22 and the grooves 13-16 of the guides 9 and 10 represent the mechanism for turning the gates. Guides 9 and 10 are placed in bearings 23. The direction of movement of the pusher is alternately supplied with compressed air into the front or rear cavity of the pneumatic cylinder 1 due to the action of the ruler 24 on the brake spool 25 or 26. To keep the hooks 11 and 12 in the rotated position, they are provided counterweights 27. Cargo 28 is supplied on conveyor 29 to the collision site.

The pusher works as follows.

In the initial position, the gates 11 and 12 are in their extreme left position. At the approach of the load 28 on the conveyor

29 to the collision site, air is supplied to the rear cavity of the cylinder 1 and the rod 2 begins to push. Simultaneously with the extension of the rod begin to move

carriages 7 and 8, which transmit forward movement to the slide valves 11 and 12, as a result of which the load 28 begins to collide with the conveyor 29. Before the end of the collision, the cheek 4 with its stops 6 rests on the yoke 18, which receives movement along the guides 9 and 10 and its fingers 20 and 22 acts on the spiral grooves 14 and 16, as a result of which the guide 9 with the gate 11 rotates clockwise,

5, the guide 10 with the gate 12 rotates counterclockwise. At the end of the stroke, the ruler 24 acts on the brake spool 26, which switches the compressed air into the forward cavity of the pneumatic cylinder 1, as a result of which the gates

0 11 and 12 in the rotated position move to the initial position, while passing over the next load on the conveyor 29. Before returning to the initial position, the cheek 3 with its stops 5

5 reaches the crosspiece 17, which receives movement along the guides 9, 10 and with its fingers 19 and 21 acts on the slots 13 and 15, as a result of which the guide 9 with the gate 11 turns counterclockwise and the guide 10 with the gate 12 turns clockwise, i.e., gates 11 and 12 are again returned to their original position — the collision position. At the end of the stroke of the rod 2, the ruler 24 acts on the brake spool 25, which switches the compressed air into the rear cavity of the pneumatic cylinder 1, and the cycle repeats.
