SU1239055A1 - Device for group feeding of articles - Google Patents

Description

The invention relates to mechanical engineering and can be used to form groups of products in automatic lines and conveyors.

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

FIG. i schematically shows the proposed device, top view; in fig. 2 is the same, the initial position} in FIG. 3 - the same, after pushing the products.

The device comprises a housing 1, a three-shouldered slam-shut lever 2 with a spring 3, a power pneumatic cylinder 4, a product availability sensor 5, a carriage 6 with a pusher 4, filled in the form of a two-armed U-shaped lever with a spring 8. On the carriage. and the stop 10, ka housing 1 - the stop 11. The stops 10 and 11 are made adjustable.

The device works as follows

In the initial position (the pneumatic cylinder rod is extended) the carriage 6 is in the extreme left position. The push rod rests against the spring-loaded end of the support 11 of the housing 1, the other horse is open to allow free flow of cylindrical articles that are fed, for example, 5 belt conveyors or a rotating disk to the fixed tray 12. Triple-shouldered

chag-cutter 2 under the action of t -. gi 9 (ha ha to reduce overall dimensions made l of off-line), the spring 3 exerting the force of the spring, is turned so that the right shoulder blocks the way

products, and the left open dp their passage.

On command from sensor 5 in the presence of products, the carriage 6 is connected with

pneumatic cylinder 4, begins to move to the right.

As the carriage moves away from the fixed support 11, the pusher is rotated around the axis up to the stop 10 of the carriage by the action of the spring 8, and the pusher 7 takes the position shown by a dotted line. Simultaneously, as the carriage moves, the backlash ha ha 9 releases the middle shoulder of the three-shouldered

the trimmer lever and it is rotated (shown by dotted lines) under the action of the spring 3, its left shoulder blocks the path of the next product after the cut-off group, and the right one opens a passage for the product group. The three-shouldered squeeze lever lags behind in this position until the pushing stick returns to its original position. After the pusher has entered into interaction with a group of products, it pushes them by a predetermined amount depending on the stroke of the single cylinder pneumatic cylinder.

After the pneumatic cylinder rod reaches the end, a return command is given. When the carriage moves to the initial position of the carriage, the end of the pusher rests against the stop 11 and the pusher, overcoming the resistance of the spring 8, turns around the axis, opening the way for the flow of products. T he 9 enters into interaction with the shutter-lock 2, overcoming the resistance of the spring 3, returns it to the original

position. Then the cycle repeats.
