Description

The invention relates to the building materials industry and can be used in the manufacture of ceramic products, for example, bricks, drainage pipes, etc., for laying them on drying cars. There is a known device for the automatic dispensing of pallets from a cassette of a package forming machine, including retractable pins hinged on the frame by means of levers interconnected by a pull and kinematically connected to drive 1. This device provides for the removal of the load from the weight of the pallets from the output pallet the account of the interaction of the retractable pins with the grooves of the next for the issued pallet, i.e. assumes the presence of special grooves in the pallets and is not applicable when working with any pallets. Closest to the present invention is a device for the single delivery of pallets, containing a magazine, a drive chain conveyor, and a pushing stop 2. The described device is complex in design and not sufficiently reliable due to the need to hold the frame frame with cams in case of issuing the lower frame. The purpose of the invention is to increase reliability in operation. The goal is achieved by the fact that the device for the single delivery of pallets containing its store, the drive chain conveyor and the pushing stop, is equipped with a supporting rod with spring-loaded rollers and a two-row non-driven roller conveyor, the chain conveyor is made in the form of successively located and kinematically connected with each other sections, pivotally connected to the floor bar, the two-chain non-driving roller table located under the pallets shop, and the pushing stop is mounted on the carrier rod, installed with the possibility of displacement, between the rows of the roller table. FIG. 1 shows a device, side view; in fig. 2 - the same plan view; in fig. 3 - the position of the device at the time of issuance of the pallet; in fig. 4 - the same, after the delivery of the pallet; in fig. 5 is a view A of FIG. one; in fig. 6 is a section b-b-in FIG. one; in fig. 7 is a section bb of FIG. 3. The device comprises a frame 1 on which a shop 2 and a chain conveyor 3 with a pusher are mounted. 4. The magazine consists of guide corners 5 and 6 of the strut 6 and is attached to frame 1 with a wrist of brackets 7, a stack of pallets 8 is stacked in the shop 8. Under magazine 2 on frame 1, a two-row non-drive roller conveyor 9 is assembled, consisting of two rows of roller cones 10. The chain conveyor 3 contains two identical in length and successively located chain sections 11 and 12, each consisting of two vertically closed chains 13, enveloping the end sprockets 14 and 15. Both sections are kinematically connected to each other and supplied with a drive 16. Chain branches resting on strip 17, mouth Installed on the frame 1. The pusher 4 is designed as a carrying bar 18 with a pushing abutment 19, equipped with spring-loaded rollers 20. The carrier bar 18 is pivotally connected to sections 11 and 12 of the chain conveyor 3, the distance between the hinges being equal to the distance between the axes corresponding end stars And or 15 sections 11 and 12. The device operates as follows. When the magazine is loaded, 2 stops of the pallets 8 rest on the roller conveyor 9. Only the bottom pallet is allowed to exit the store along its axis. In the initial position, the stop 19 of the rod 18 is outside the magazine 2. When the actuator 16 is turned on, the chains 13, which move the pivotally linked pusher, are driven. 4. The stop 19 acts on the lower pallet 8, rolling it out on the roller table 9 outside the store. 20 pusher 4 then approach the next pallet, during the interaction they take off their springs, go under it, as the pushers move, take up all the effort from the mass of the pallet foot. When the bottom pallet leaves the store, the hinges of the connection of the pusher 4 with chains 13 roll over the end sprockets 14, the transition to the lower branch of the chains 13, and the plane of the support of the foot of the pallets lowers and they are mounted on the live rolls 9. Continuing movement, the chains 13 roll around the hinges of the joint a pusher with chains around the end sprockets 15, after which the actuator 16 is turned off. The cycle of delivery of the pallet is over. The use of the device ensures that when the pallet is dispensed, the remaining stack of pallets is held in a strictly horizontal, without distortions, position, and smooth plane-parallel transfer of the pallets to the initial position, ie, increases the reliability of work.
