Description

The technical solution relates to machine tool building, namely to devices for automatic loading of technological machines and automatic lines with parts such as low thin-walled caps (metal or plastic), used, for example, in the food industry for capping bottles.

Known disk gear hopper loading device containing a hopper formed by the shell and the base, a rotating disk with gripping bodies made in the form of through sockets, alternating with protruding teeth, and radial grooves extending from the center of the disk to the sockets (see in the book. Systems of automatic Usenko N.A., Preis V.V., Davydova E.V., Bocharova E.S., scientific editor V.V. Preis, Tula : TulGU Publishing House, 2013. pp. 78-80, Fig. 4.10).

The disadvantage of this hopper loading device is the impossibility of loading parts such as low metal or plastic thin-walled caps, the height of which is less than their outer diameter.

A bunker loading and orienting device is known, containing a bunker formed by a shell and a base, a rotating disk with gripping elements made in the form of radial grooves made with a slope directed towards the periphery of the rotating disk (ed. mon. USSR No. 921773. M. Kl. ³ V23Q 7/02 Bunker load-orienting device / N. I. Solovyov, N. P. Solomin, publ. 23.04.82, Bull. No. 15).

The disadvantages of this bunker loading and orienting device is its low reliability when loading parts such as low metal or plastic thin-walled caps, the height of which is less than their outer diameter, while having a slight chamfer or rounding along the edge of the closed end, as well as the possibility of damage to the loaded caps by mechanical orienting elements of the device.

The objective of the technical solution is to increase the reliability of the bunker loading and orienting device when loading parts such as low metal or plastic thin-walled caps, the height of which is less than their outer diameter, while having a slight chamfer or rounding along the edge of the closed end, as well as eliminating the possibility of loaded caps.

The specified technical problem is solved due to the fact that the hopper loading and orienting device for low thin-walled caps contains a hopper formed by a shell and a base, a rotating disk with grippers in the form of radial grooves made with a slope directed towards the periphery of the rotating disk.

What is new is that in the upper part of the bunker at the base along a circle passing through the centers of the radial slots, and the width of the radial slot, a through slot is made that communicates with the atmosphere, and opposite the through slot in the radial direction to the center of the rotating disk at a distance a determined by the dependence a =(0.5…0.75)D, where D is the outer diameter of the low thin-walled cap, a through hole is made for supplying compressed air.

The essence of the technical solution is illustrated by drawings, where:

in fig. 1 shows a diagram of a bunker loading and orienting device in a section along the axis of rotation of a rotating disk, general view;

in fig. 2 shows view A of FIG. 1;

in fig. 3 shows a section along B-B of Fig. 2, illustrating the position in the radial groove in the upper part of the hopper of a low thin-walled cap sunk with its closed end up;

in fig. 4 shows a section along B-B of Fig. 2, illustrating the removal from the radial groove in the upper part of the hopper of a low thin-walled cap sunk down with its closed end down.

The bunker loading and orienting device for low thin-walled caps 1 contains a hopper formed by a shell 2 and a base 3, a rotating disk 4 with grippers in the form of radial grooves 5 made with a slope 6 directed towards the periphery of the rotating disk 4.

In the upper part of the bunker in the base 3 along a circle passing through the centers of the radial grooves 5, and the width of the radial groove 5 is made through the slot 7, communicating with the atmosphere. Opposite the through slot 7 in the radial direction to the center of the rotating disk 4 at a distance a determined by the dependence a = (0.5 ... 0.75) D, where D is the outer diameter of the low thin-walled cap 1, a through hole 8 is made for supplying compressed air.

Bunker boot device works as follows.

When the rotating disc 4 rotates, low thin-walled caps 1, filled into the hopper, fall into the radial grooves 5 and move them to the upper part of the hopper.

When moving in the zone of the through slot 7 and the through hole 8 of low thin-walled caps 1 sunk into the radial groove 5 with the closed end up, the compressed air supplied through the through hole 8 freely passes through the internal space of the cap 1 and through the through slot 7 goes out into the atmosphere. As a result, the caps remain in the radial groove 5 and, with further rotation of the rotating disk 4, they move to the receiving window (not shown in the figure) and are issued from the hopper load-orienting device.

When moving in the zone of the through slot 6 and the through hole 7, low thin-walled caps 1 sunk into the radial groove 5 with their closed end down, the latter, with their closed end, cover the through slot 7 and the through hole 8 located opposite the through slot 7 in the radial direction towards the center of the rotating disk 4, since the through hole 8 is made at a distance a determined by the dependence a = (0.5 ... 0.75) D, where D is the outer diameter of the low thin-walled cap 1. As a result, the compressed air supplied through the through hole 8 lifts the caps 1 in the radial groove 5, and they fall out along the slope 6 directed towards the periphery of the rotating disk 4 under the action of a jet of compressed air and gravity back into the bunker.

Thus, this technical solution will increase the reliability of the bunker loading and orienting device when loading parts such as low metal or plastic thin-walled caps, the height of which is less than their outer diameter, while having a slight chamfer or rounding along the edge of the closed end and eliminate the possibility of damage to the caps during loading due to the absence of mechanical orienting elements in the bunker loading and orienting device that are in rigid contact with the loaded caps.
