The purpose of the invention is to simplify the design and ensure the readjustment of the conveyor to any size of parts. Guides for parts are installed on the base, drive 3 of reciprocating movement of the cross-member (T) 4.5 with grippers 6., Drive 3 is designed as a power cylinder with two rods b, on which the toothed racks are attached. Between T 4.5 there are vertical axes on which the faceplate 12 and the gear sector 11 are mounted in series with the possibility of rotation. On the latter, the latch 13 is hinged in the form of an L-shaped lever. The toothed sector 11 is engaged with the toothed rack and the wheel 14 by means of a latch 13 °. The washer 12 has four radial grooves in which spring-loaded sliders 20 are mounted to the cam. There are rollers 21 located on them, interacting with T 4.5 When the actuator rod moves, the face plates 12 with rollers 21 turn, moving T 4,5 in the longitudinal and Transverse directions. The grippers at the beginning of the turn out of engagement with the F 27, and at the end of the turn capture the neighboring F 28. At the return stroke of the stem T 4,5, they make only a longitudinal movement and move F into a step. 4 il. I SL

The actuator 3 is made in the form of a power cylinder 7 with two rods 8 on which toothed rails 9 are fixed. Between the cross-bars 4.5 there are vertical axes 10 on which the toothed sector 11 and the faceplate are mounted sequentially and rotatably. The toothed sector 11 is hinged the latch 13 is made in the form of a G-shaped lever. The wheel 14 has four symmetrically arranged radial grooves 15, and the L-shaped lever is installed with the possibility of positioning the wheels 14 in the grooves 15, which is rigidly fixed on the faceplate 12 from the toothed sector 11.

The toothed sector 11 is engaged with the toothed rack Y and to the wheel 14 by means of a spring-loaded latch 13o. On the base 1 there is a stop 16 for engaging the latch 13.

On the faceplate 12 with the possibility of rotation and fixation is cam

When the piston of the power cylinder 7 moves to the initial position, the rod 8 moves the rod 25 to the right by raising H, and the gear racks 9 rotate the gear sectors 11 back by an angle of 90 °. The latches 13 at the beginning of the reverse rotation of the gear sectors 11 exit from the interaction with the stops 20 and engage with the wheels 14 only at the end of the return stroke of the ram.

Ba 12 has four radial grooves 19 in which sliders 20 are placed, spring-loaded to the working surface of cam 17 with rollers 21 mounted on sliders 20 by means of vertical axes 22 and freely rotating on them. The slides 20 are clamped to the cam 17 by the springs 23. The rollers 21 are arranged to interact with the cross-pieces H and 5 by means of the springs 24. The rods 25 are for the cross-arms 4 and 5, transverse guides.

The rod 8 of the power cylinder 7 is connected to one of the rods 25 bracket- 2b,

The stepping conveyor works as follows. I

When the piston of the power cylinder 7 moves to the left (see FIG. 1) to the distance H, the rod 8 moves the rods 25 to the left to the distance H, and the toothed racks 9 rotate the toothed sectors 11 and the wheels 14 and the face plates 12 sec. , rollers 21 clockwise at an angle equal to 90 °. At the end of the rotation of the toothed sector 11, the latch 13 enters, engages with the stops 16 and disengages from the wheels 14. The end of the rotation of the faceplate 12 occurs. due to the force of compression of the springs 24, acting through the traverse 4 and 5 on the rollers 21. As a result of this traverse 30

distance and move the vials 27 and 28 one step to the right.

The washer 12 with the rollers 21 is stationary at this time.

With the next movement of the piston of the power cylinder 7 to the left, the cycle of operation of the device is repeated.

In order to move the vials 7.28 of smaller or larger cross-section, the screws 18 are turned 2-3 times. After this, the cams 17 are turned to the corresponding angle clockwise or counterclockwise. As a result, the slide blocks 20 with the rollers 21 move along the grooves 19, and the distance between the cross-pieces 5,4 and, hence, between the working surfaces of the grips 6 changes in accordance with the diameters of the bottles being transported.

The proposed conveyor has a simple construction, small dimensions and is equipped with a device for providing the possibility of changing the distance between its load-carrying elements, which makes it possible to transport vials of another size with an easy changeover.
