Description

one

The invention relates to industrial transport, namely, to conveyors for the longitudinal transport of pieces

LI.

Conveyors are known for the longitudinal transport of cylindrical piece goods containing a frame with vertically closed traction chains mounted on it, an envelope, drive and tension sprockets, as well as supporting elements for the chains and fixed on the load chains.

The proposed conveyor differs from the known ones in that each of the traction chains along its entire length is provided with vertical rollers on which blocks are fixed, enveloped by a common closed flexible connection that passes alternately from one block to another block, and the supporting elements are in the form of located between the chains of pressure chambers, equipped with protruding power plugs carrying intermediate sprockets at the ends, interacting with the corresponding branches of the traction chains, and the drive and tension sprockets of the traction chains They are mounted on shafts through sliding keys to allow chains to come together from the drive for moving the tensioning sprocket. This allows the axes of cylindrical articles to be maintained at a constant height.

FIG. 1 shows the proposed device; in fig. 2 is a section along L-A in FIG. one.

The conveyor contains two traction chains 1 with load-carrying supports 2 and blocks 3, two drive 4 and two tension 5 sprockets, installed in pairs on shafts, respectively 6 vi 7, on sliding keys. The traction chains 1 are interconnected by a flexible coupling 8, passed through the blocks 3. The shaft 7 of the tension sprockets 5 is connected to a drive, giving it a reciprocating movement.

When laying another pipe on a device

diameter expose its longitudinal axis coaxially with the machine by moving the tension sprocket 5 with the drive shaft 7. Moreover, if the size of the next pipe is smaller than the previous one, the shaft 7 is moved to the left, thereby increasing the distance between the drive 4 and tension sprockets. Since the length of the flexible link 8 is constant, it starts to shrink, which leads to the movement of the sprockets 4 and 5 along the shafts 5 and 7 towards each other and decrease the distance between the load-carrying supports 2. Simultaneously, the displacement takes place using pressure chambers 11 power stops 9 with intermediate sprockets 10. At the same time, the pipe on the load-carrying supports 2 rises so that its axis coincides with the axis of the pipe-processing machine .-, Depending on the diameter of the pipe being transported, the shaft 7 of the sprockets 5 takes up a corresponding fix positioned. With an increase in the diameter of the pipes being transported, the direction of movement of the shaft 7 is reversed. 5 10 15 20. 25 The subject of the invention is a conveyor for the longitudinal transportation of cylindrical mechanical parts containing a frame with vertically closed traction chains installed on it, enveloping the drive and tension sprocket, as well as supporting elements for chains and fixed on the chains the load-bearing supports differing in that, in order to maintain the axes of products of a cylindrical shape at a constant height, each of the traction chains throughout its length is provided with vertical rollers, on which blocks are attached, bending around a common closed gi They are connected alternately from the block of one chain to the block of the other, and the supporting elements are made in the form of pressure chambers located between the chains, equipped with protruding force stops, carrying intermediate sprockets at the ends, and interacting with the corresponding branches of the chain of the traction chain, the drive and tensioning sprockets of the traction chains are mounted on shafts through sliding keys.
