Abstract

Use: for oriented feeding of parts such as bearing rings in automatic lines. SUMMARY OF THE INVENTION: The device comprises a feeding tray 4, at the end of which a stop 5 is installed with the possibility of adjusting movement. A rotating drum 6 with windows in which the gripping bodies 10 are arranged, made in the form of spring-loaded conical disks. The gripping organs are mounted on an additional drum with the possibility of adjustment movement relative to the latter. An additional disc is mounted on the axis of the main drum 6 with the possibility of axial movement. Parts are fed through the feeding tray 4 up to the stop 5, then captured

Description

The invention relates to mechanical engineering and can be used for the approximate supply of parts such as bearing rings with a tapered bore in an automatic line,

The aim of the invention is to increase reliability and productivity by creating additional efforts, ensuring the discharge of incorrectly oriented parts.

Figure 1 shows the device, a general view; figure 2 - drum with gripping bodies; on fig.Z - section A - A "in figure 2; figure 4 - section B - B in figure 2 (with the wrong position of the part); figure 5 - the same, with the correct position of the part.

The method of orientation of parts with a conical hole is that the part is fed through the feeding tray up to the stop, picked up one by one by conical discs, rolling in relative to the stop, as a result of which an instantaneous rise of the part relative to the conical disc takes place, and then contact located at the lower end of the drum, are ejected from the conical disk by the action of the arising reactive forces. Parts located with a large end to the drum are pressed against it and transported to the discharge chute.

This method is implemented by a device for orientation of rings with a conical opening containing a stationary body 1, a hopper 2, an elevator 3, a feed tray 4 at the end of which an adjustable stop 5 of cylindrical shape is fixed. In case 1, a drum b with windows 7 is rotatably mounted. The axis of rotation of the drum b is mounted with the possibility of axial movement of the drum 8. On the drum 8 there are two double-arm levers 9 pivotally mounted, at one end of which there are conical disks 10 with the possibility of adjustable movement. installed in windows 7 above the end of the drum 6 and are designed to grip the parts. The levers are connected to the drum 8 by means of a spring 11. The free shoulder of the two shoulders lever is arranged to interact with an adjustable stop 12. A discharge tray is installed on the body 1 to reset incorrectly oriented parts 13, and for properly oriented, discharge tray 14,

The device works as follows.

From the hopper 2, with the help of an elevator 3, the parts enter the feed tray 4 to

stop 5, the Part is captured by a conical disk and transported to the discharge chutes. Those parts that are fed to the gripping body with a smaller end face, with the rotation of the drum 6, slide off with

the conical disk 10 and again enter the hopper 2 by means of the discharge tray 13. The parts entering the input tray 4, with their large end facing the drum 6, are pressed against its end and enter

discharge tray 14.

When supplying parts of another size, the movement of the stop 5 and the conical discs is carried out.

Claims (3)

1. The method of orientation of rings with a tapered hole, which consists in the fact that the parts are fed through the feeding tray up to the stop, are individually captured by the gripping elements of the drum and are produced in the process transportation dumping incorrectly and correctly oriented parts for different discharge trays, characterized in that, in order to increase reliability and performance, at the initial moment transporting the part by the gripping body is carried out rolling it against the stop. 2. A device for orientation of rings with a tapered bore, comprising a stationary body, a feed tray with a stop at the end, two discharge chutes and a rotatably mounted drum with gripping bodies, characterized in that, in order to increase reliability and performance, the gripping bodies are in the form of spring-loaded conical disks and are located at the end of the drum, and the delivery tray is arranged parallel to the said end of the drum. 3. The device according to claim 2, characterized in that it is provided with an additional drum mounted on the axis of rotation of the main axis with the possibility of axial movement relative to the latter, and the gripping bodies are mounted on the additional drum with the possibility of adjustment movement in additionally made windows in the main drum, the stop is mounted with the possibility of adjusting movement relative to the body of the feeder. 0 4 A device according to claim 2, 3, characterized in that each conical disk is connected to an additional drum by means of an additionally inserted spring-loaded two-arm lever pivotally mounted on an additional drum, on one arm of which a conical disk is positioned with adjustable movement, and the possibility of interaction with the additionally introduced adjustable stop mounted on the additional drum. fie .5 J BUT eleven thebes. 3 Bb / L g ID / ten at
