(54) ELEVATOR FOR TRANSPORTATION OF PIECE CARGOES

one

The invention relates to industrial transport, namely, elevators for transportation. piece goods.

The known elevator contains traction chains, on which carriers are fixed, each of which is made of two pivotally connected parts — fixed and mobile, and a star-shaped pusher for interacting with the movable part of the carrier at the place of their unloading 1.

However, this elevator is intended for transporting bulk cargo and is not adapted for transporting cylindrical products.

Also known is an elevator for transporting piece goods, containing two parallel traction chains, the outgoing branches of which are passed through a bunker with a load mounted on the frame, carriers, made in the form of plates attached to the links of both chains, and having , guides for carriers and receiving tray 2.

The disadvantage of such a device is the limited range of parts transported along the diameter due to the constant size of the cargo cradle. In order to transport parts of a different size, it is necessary to change the plates, which is technologically disadvantageous.

In addition, the unloading position in the device depends on the position of the upper tensioning sprocket and varies depending on the wear of the chains, their stretching, therefore, additional adjustment of the receiving part of the parts is necessary.

The purpose of the invention is the expansion of technological capabilities.

To achieve the goal, each plate is made of two pivotally connected parts, the upper part of which is fixed to the chain, and the lower part is spring-loaded relative to the upper part and is provided with a photocopier roller, and the frame is equipped with a movable one. in the direction of the load-carrying branches of the chains with a cam and cam, located opposite the receiving tray.

20 In addition, the cam is movable along the vertical axis of the elevator.

FIG. 1 shows the proposed device, a general view of FIG. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2;

Two parallel traction chains 3, enveloping tension and leading sprockets 4 and 5 are passed through the hopper 1 with the products 2. The chains are fixed to the carriers, each of which consists of a top plate 6 rigidly attached to the chain with a lodgement 7 for the load and pivotally attached to the plate 6 of the bottom plate 8 with a roller 9. The plates 8 are elastically preloaded by the springs 10 on the load carrying branch to the copier AND located at the receiving tray 12. The copier I is mounted on the cranks 13, which allow the copier 11 to move in the direction of the carrying branches and back. The cam 14 is mounted on the frame 15 with the possibility of movement along the vertical axis of the elevator. On the load-carrying branch of the elevator, two pairs of guide bars 16 and 17 are attached to the frame 15, between which the edges of the plates 6 are placed.

Chains 3 are driven by a drive (not shown) and continuously move the load carriers through a layer of items 2 poured into bulk into the hopper 1. When the chain 3 moves, the edges of the plates 6 of the carriers go between the guide bars 16 and 17. When the roller 10 rolls on the copier 11, the plates 8 are deflected at an angle X, thereby forming a lodgement 7, adjustable depending on the diameter of the product being transported 2 by moving the copier 11. The products 2 sink into the lodgement 7 and move up to the receiving tray 12. Resetting the products 2 to the tray 12 happen t due to the rotation of the plates 8 in the counterclockwise direction when roller 10 rolls onto cam 14. After roller 10 rolls from cam 14 plate 8 under the action of springs 10, rotate clockwise relative to plate 6 and become in the extreme position defined by the stopper in the hinge. In this position, the carriers remain until the next capture of products from the bunker.

If necessary, the moment of discharge of cargo from the cradle 7 is adjusted by moving the cam 12.

The proposed elevator makes it possible to transport products of different diameters and lengths, which makes it more technologically advanced.
