Description

one

The invention relates to the automation of technological processes and can be used in automated assembly lines.

Devices for piece-by-piece dispensing are known, which are a mandrel with holes through which parts are individually delivered to the disk. A sleeve is fitted on the mandrel with two horizontal rows of flat springs. At the extreme upper position of the sleeve, the upper row of flat springs hold one hundred parts through balls located in special grooves of the mandrels, and the lower springs release the lower balls, the part onto the disk under the action of its own weight. With the lowermost position of the sleeve, the lower row of flat springs, pressing on the lower row balls, partially overlap with the supply feed part balls and the upper springs release the upper row balls — the column of parts goes down to the lower balls ij.

This device cannot be used to issue parts such as rings, which have

significantly less diameter, as well as heavy parts.

The purpose of the invention is to provide an opportunity to reliably produce parts of a cylindrical shape that do not have chamfers, but interlock with each other due to the presence of a protrusion on one of their ends, and a hollow on the other.

To do this, in the proposed device, consisting of a magazine and a cut-off mechanism, two rings are successively mounted on the body of the magazine, coaxially with it, with spiral and step grooves respectively on the inner surfaces of the upper and lower rings opposite the spherical holes.

FIG. 1 shows the device described, section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section E5-B in FIG. 1.

The device consists of a magazine case 1 with two rows of spherical holes, the top 2 and bottom 3. On the outer surface of the case magazine 1 there are two rotary rings, the top 4 and the bottom 5. The top ring 4 contacts through spiral slots 6. with balls 7 of the upper p -

yes, and the lower ring 5 — with balls. In the lower row, through a two-step groove 9. The rings are spring loaded with 10 tension springs. Plug And, located on the upper ring 4, serves to rotate and return the ring to its original position, and the stop 12 of the ring 5 - to rotate this ring in the clockwise direction.

In the initial position, the stack of parts lies on the balls 8, which have been pushed through the spherical holes 3 along the two-tongued grooves 9, as on the stops. When the upper ring 4 is rotated clockwise along the spiral grooves 6, the balls 7 of the upper row move up to the stop into the part 13 and clamp it. Then the lower ring 5 is rotated clockwise, while the lower balls 8, the weight of the part, go to the grooves 9 and release the lower part, which falls down. The stack of parts rests on the clamped part 13.

When the ring 5 returns to its initial position under the action of the spring 1O, the lower balls 8 move to their initial position along two-step grooves 9 through spherical holes. After turning the ring 4 for the fork 11 counterclockwise detail

13, the stack of parts is released, moving inward, lies on the protruding lower balls 8. Kolya 4 is held in its initial position by the spring 30,
