Description

Devices for rejecting various objects using a circular conveyor, a sorting device, and several outlets and ejectors are already known. In such devices, electromagnetic devices are sometimes used to control ejectors and other devices.

The proposed device is designed to reject cans by weight, and this device also uses a feed conveyor and a rotary table with several taps fitted with ejector controlled by means of electromagnets, but with the aim of removing the cans from the table when their weight deviates from the standard On the other hand, can stand supports are equipped with rods connected with lever weights pre-installed on the back weight and provided with contact rollers at the lower end placed in a shaped ring groove.

In order to actuate the ejectors, in order to remove the rejected cans, the said groove is provided with upper and lower cuts allowing the rollers to be fixed in them, with a correct weight of the can and the inclusion of corresponding contacts acting on the electromagnets.

In FIG. 1 shows a general view of the device from above; FIG. 2 - the same, side view; FIG. 3 - a general view of the unfolded annular groove; FIG. 4 shows a section along the line AB in FIG. 3; FIG. 5 shows a section along the line CD in FIG. 3

The rolled up bank, moving along the plate conveyor 1, enters the rotating table 15. A feed sprocket 14 centers the position of the cans exactly above the supports 20, which rotate with the table. Each stand 20 is mounted on the rod 17, which ends at the bottom with two contact rollers: mi 18 and 19. The roller 19 is placed in a fixed shaped ring groove 16, the contact roller 18 is on the same axis with the first roller and serves to close the contacts in case The weight of the can will not be standard.

For a clear view of the operation of the device, the design of the annular groove 16, which plays the role of a damper, should be considered.

The cans are loaded when the roller 19 together with the stem and chuck are in the position between the points V and VI of the annular groove. In this case, the stand 20 is located at table level 15, allowing the bank to take its place. After that, and position VI, the roller, together with the can, rises and moves in the annular groove.

In this case, there are three positions;

1.If a standard weight bank is balanced by a counterweight 21 (lever weights 17, connected with rods 17, - and later, when moving in a ring groove, it produces pressure ”and the upper or lower flanges of the annular groove.

2. If the weight of the can exceeds the standard, the balance is disturbed, the stand produces pressure on the lower cavity of the groove 16.

3. If the weight of the can is less than the standard, the balance is broken and the stand 20 through the roller 19 produces pressure on the upper plane of the groove 16.

If it is assumed that a bank having a weight higher than the standard arrived at the stand 20, then the balance is disturbed, the counterweight 21 rises, and the rod 17 goes down, and the roller 19 will all the time exert pressure on the bottom polka of the ring groove, as a result of which I - II rod 17, due to the gift of cutout C, is lowered down. Simultaneously with the roller 19, the contact roller 18 is lowered. The roller 18, touching two contacts 13, closes the DC circuit. In addition to this, the Katuat electromagnet 8 pulls the lever with the ball 9 and, through the link 10, turns the ejector 11 so that it blocks the path and Displays it at point 12.

If the weight of the canister does not exceed the standard, then roller 19, exerting pressure on (the upper shelf, will move along the groove and at point III will rise upwards, continuing to move in cutout B (section III-IV);

the roller 18 also lifts and closes the electrical circuit, and the ejector 11 with the help of an electromagnet 8 will block the path of the bank and bring it to point 4. At this time, the spring 6 will deliver the ejector And to its original position.

Banks of standard weight move in such a way that in position I-II or III-IV they rise or o-start or oscillate so that the contact roller does not touch contacts 5 or 7, as a result of which the electrical circuit remains open. In the V position, the can bank roll is lowered, after which the can is bumped onto a non-movable pick-up 3 and is diverted along point 2 to the finished product warehouse.

The subject matter of the invention.

Claims (2)

1. A device for rejecting cans by weight, with the use of a feed conveyor and a rotary table with several outlets equipped with ejectors controlled by electromagnets, so that, in order to remove the cans from the table 15, when their weight deviates from the standard in one direction or another, the supports for cans 20 are provided with rods 17, connected with lever weights 17 previously installed on a given weight and equipped with contact rollers 18 and 19 at the lower end, placed in a shaped ring groove sixteen. 2. The form of the apparatus according to claim 1, in which, for actuation of the ejectors 11, 1G, in order to remove the rejected cans, the groove 16 is provided with upper (b) and lower (c) cut-outs, enabling the zapadan in their rollers 18 and 19 when the jar weight is incorrect. And turning on the contacts 5 and 7, acting on them on electromaps 8 and c. fig L 4 FIG. Y fig.i fig
