(54) DEVICE FOR ORIENTED DELIVERY OF PARTS

I

The invention relates to the automation of loading devices and can be used for the oriented feeding of parts such as washers, nuts, and caps in vibrating hoppers.

Devices are known for oriented feeding of parts such as washers, nuts and caps in a vibrating hopper, comprising a cutter in the form of a shelf installed at an angle above the tray with a beveled surface 1.

A disadvantage of the known device is that at a weakly pronounced asymmetry or the ratio of the diameter of the part to its height, close to one, the part under the shut-off device is wedged.

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

The goal is achieved by making the angle between the tray and the shelf widening in the direction of flow of parts, with one end of the shelf, along the movement of the stream of parts along the tray, is installed below and the other end of the shelf is above the level of the part and across the tray

the angle between the shelf and the chute expands by 3-5 ° to the wall of the vibrating hopper.

FIG. 1 shows the proposed device in plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one;

5 in FIG. 4 - types of sorted parts. The proposed device comprises a shelf 1 with a flat surface 2 fixed on the wall of the hopper 3 at an angle to the tray 4 in the direction of movement of the part 5 so that the distance between one

The 10 end of the shelf and the tray is less than the level of the supplied part 5, and the distance between the other end of the shelf and the tray 4 lies within the level of the supplied part, which is in a condition of stable equilibrium along the edge 6 of the tray 4. In the plane pendicular bevel, the shelf is set relative to tray 4 with the rise in the direction of the wall of the hopper 3 at an angle of 3-5 °, mainly due to the inclination of the tray 4. The device works as follows.

20 Orientable parts 5 in a stable equilibrium position are driven by the vibration of the hopper and the tilt of tray 4 along the edge of the surface 2,

contact with her constantly. Parts running in unoriented positions have a slightly larger envelope above the tray or surface shape, causing their center of gravity to be removed from the edge of the curved surface 2 of the shelf 1. This creates an unstable position on the edge of the tray and they fall to the bottom of the bunker's chest.

The efficiency of sorting parts with the ratio of the diameter to the height of the part () close to 1 in the proposed device is achieved by moving the oriented parts 5 along the flat surface 2 until such time that the size between the shelf 1 and the tray 4 expands during the movement of the part allows them to pass under shelf 1 without a gap and adopt a sustainable oriented position. Raising the shelf 1 in the direction of movement of the parts and the expanding angle (3-5 °) towards the wall of the bunker prevent them from jamming under the shelf 1. The angle of elevation is chosen depending on the ratio - (Configuration and degree of asymmetry of parts.

The proposed device allows to extend the technological capabilities of sorting by eliminating jamming.
