(54) ELEVATOR FOR PIECE CARGOES

one

The invention relates to industrial transport, in particular to elevators for unit loads.

The Elevator d, n piece goods, containing traction chains, covering drive and tension sprockets and equipped with shelves, as well as loading and unloading trays 1, are known.

The elevator is not adapted to feed products into the subsequent manufacturing operations, therefore, when used in production lines as intermediate devices, additional feeding devices are required.

A well-known elevator for cargoes is known, which contains a frame with cranking and tensioning sprockets installed on it, traction chains with load-carrying shelves fixed on them, over each of which visors are made, and loading and unloading chutes 2.

A disadvantage of this device is that not all the sub-shelves are filled with items when the traction chains pass through the loading tray, which reduces the performance of the elevator.

The purpose of the invention is to increase the productivity of the elevator.

The goal is achieved by the fact that the load carrying shelves of each chain are shifted relative to the shelves of the adjacent chain by half a step of their g position on the chain, and in the loading tray between the traction chains there are slots, and the loading tray is provided installed in slots and kinematically connected with drive sprockets vertically closed chains with blades, 10 working surfaces of which are made with a slope in the direction of the traction chains.

FIG. 1 shows a grain elevator for piece goods, a general view; in fig. 2 - elevator carriage; in fig. 3 - loading tray.

Claims (2)

The elevator contains the frame 1, in the lower part of which the loading tray 2 is located. The tray has an inclined bottom with slots 3. The width of the slots 3 is smaller than the diameter of the transported products, which prevents them from falling out of the tray 2. Inside the frame there are traction chains 4 covering the nat Sprockets 5 and mounted on the drive shaft 6 of the elevator drive sprockets 7. To the load chains 4 are attached carrying shelves 8 made in the form of buckets, fitted in the upper part with a visor 9 located at a distance of one and a half transport diameters rotated products, which ensures the capture of shelves of no more than one product. Shelves 8 are mounted to their chains so that they are offset from the shelves next to the passing chain 4 by half a step. In addition, in the loading tray 4 of the elevator, endless chains 10 are mounted, mounted between the traction chains 4 obliquely to their vertical axis and passing inside the loading tray 2 through the shells 3 in its bottom. Chains 10 thus include drive sprockets 11 on a drive shaft of 6 t chains of chains 4, tension sprockets 12 mounted above the upper level of the loading chute 2, and tension spring-loaded rollers 13 mounted on levers 14 on the frame 1 under the loading chute. The chains x 10 are fastened obliquely to the blades 15 in which the angle of inclination to their chains is greater than the sum of the right angle and the angle of inclination of the chains 10 to the vertical axis of the traction chains 4. Such an attachment prevents fragile articles being transported from mechanical damage. The working surface of the blades 15 is tilted in the direction of the branches of the traction chains 4 passing this. This ensures that the products from the blades of the agitator move towards the traction chains 4 with the buckets 8 and creates a directional flow of products. Spring-loaded rollers 13 increase the flexibility of the blades when they stop in the product. In the upper part of the frame 1 is installed discharge chute 16, having a vertical wall 17, which facilitates the piece unloading of products. The elevator works as follows. Products to be transported are poured into the loading tray 2, where the blades 15 are constantly agitated. These same blades, due to the inclination of their working surfaces towards the working chains 4 with shelves 8, create a flow of products to the area of their capture. From the created flow, the products are taken along one shelf 8 and transported to the discharge chute 16. Offset by half the step of the shelves of one branch of the traction chains 4 relative to the other chain also contributes to the capture of the products when the latter are rolled down from the upper shelves to the lower. The proposed elevator increases the likelihood of filling the entire floor, ok and thereby increases its productivity. An inventive grain elevator comprising a frame with drive and tension stars attached to it, draw chains with load-carrying shelves fixed to them, each with visors made, and loading and unloading chutes, characterized in that , the load-carrying shelves of each chain are shifted relative to the shelves of the adjacent chain by half a step. Their location on the chain, and in the loading tray between the traction chains there are gaps, and the loading tray is provided with x in ment of slots and kinematically coupled with the drive wheels vertical closed chains with blades working surfaces which are made sloping towards the traction chains.
