Description

one

The invention relates to the automation of technological processes in mechanical engineering and can be used when loading machines and assembly machines.

A device for orientation of parts is known, which contains a vibro-hopper with a stepped groove and an orientator in the form of an abutment installed at a distance from the stage of the groove commensurate with the length of the workpiece 1.

A disadvantage of the device is the impossibility of orientation of parts with an internal characteristic feature and a slight displacement of the center of gravity.

Another device for dividing the flow of parts and supplying them with a light end forward is known, containing 1 1. its vibration hopper and an output tray with a slot for orientation of the parts, provided with a wall and a plate in its feed part 2.

A disadvantage of the known device is the orientation of the part according to external features, which limits its scope.

The aim of the invention is to extend the technological possibilities of using the device when supplying parts with a hidden characteristic feature.

This goal is achieved by the fact that a knife-shaped protrusion and a ledge are made on the feeding part of the output tray in front of the orientation slit, and the receiving part of said output tray is made with a tilt angle exceeding the tilt angle of the feeding part.

FIG. 1 shows a device with a general view; in fig. 2-4 are the phases of the passage of a slit with a light end pointed forward.

The device for dividing the flow of parts contains a vibro-hopper (not shown), an output tray 1 with a slit 2, a knife-like protrusion 3 and a step 4 in the feeding part of the output tray 1, the receiving part 5 of the output tray 1, made with a slope angle exceeding the angle of its feeding part .

The width of the ledge is selected within (ac), and the slits, where b is the width of the ledge; О- - gap width;

from the center of gravity P to the end of the heavy end of the part;

e is the amount of displacement of the center of the plate P from the center of symmetry Q of the outer surface of the part; d is the distance from the center of the body P

to the end of the light end of the part. The device works as follows.

When the flow of the movement, the parts reaching the heavy end forward (with the end without an opening) sink into the slot 2 and arrive at the pick-up point or back into the capacity of the vibrating hopper for reorientation.

Parts reaching the light end forward, when the center-shaped P passing of the knife-like protrusion 3, tilt with the light end to the receiving part 5 of the output tray 1 (Fig. 2), and on further movement fall to the ledge 4 (Fig. 3).

The part is then tilted on the tip of the receiving part 5 of the output tray 1, continuing to move with a light end forward.

The proposed device is simple and reliable in operation for parts with a slight displacement of the center of gravity.
