Description

To test cans and these similar hollow articles for tightness by creating a vacuum in them and then sorting the cans into preserved and lost ones, they use machines made in the form of a turning wheel, on the shaft of which the cam is fixedly mounted located cartridges for test cans. The latter are retained on the cartridges by atmospheric pressure while the vacuum created by the bellows with a spring-loaded rod is maintained inside the cans.

The proposed machine is more advanced than the known machines, since it improves the reliability of sorting cans by tightness.

This is achieved by the fact that the bellows rods are provided with fingers, and in the course of their movement, when the wheel is inserted, two cam segments interacting with the fingers are installed. One of these 10B segments serves to control the compression of the bellows before being placed on the cartridges of the test cans, and the other to compress the bellows before separating the sealed cans from the cartridges and further stretching the bellows to hold partially vacuumed cans that are removed after removing the sealed cans cans.

FIG. I shows the scheme of the proposed machine; in fig. 2 is a diagram of its cartridge.

The machine is a rotary wheel /, on the shaft of which a cam 2 is fixedly mounted, and a radial on the rim; but the cartridges 3 for the test cans are located.

Each cartridge consists of a rubber pad 4 bellows 5 and the rod 6 (Fig. 2).

The test jars are held on the cartridges by atmospheric pressure while the vacuum created by the bellows 5 is maintained inside them. To reduce the volume occupied by air in the cartridge, a body 7 is placed inside it, equipped with a through axial channel.

No. 117156

solid pig 8 is located inside the bellows and serves to reduce the volume of air in its internal cavity.

The rods 6 of each cartridge are supported on the cam 2 and are equipped with a spring 9 with an adjusting nut 10 and a finger 11 with a roller.

When turning the wheel / rod 6, falling into the recess of cam 2, it stretches the bellows, as a result of which a vacuum is created in the cartridge with a working canning bap, holding the can when the machine is turned, the two cam segments 12 and 13 are attached to the lower part of the wheel 1, which interact with fingers 11 cartridge rods; Segment 13, when adjusted, can be displaced radially to adjust atmospheric pressure.

The fixed segment 12 controls the compression of the bellows 5 before being installed on the cartridges of the test cans. It has dried, rejecting segmented cans that slowly lose the vacuum. By moving, segment 13 compresses the bellows before separating the sealed cans from the cartridges and further stretching the bellows to hold the cans that have partially lost vacuum. He sorts out hermetically sealed cans and sends them into heat 14.

Unsealed cans, which rapidly vacuum the vacuum, are rejected by the PS of the entire wheel circumference.

Claims (4)

1. Machine for testing cans and similar hollow products for tightness by creating a vacuum in them and then sorting the cans into vacuum and losing it, made in the form of a swivel wheel, on the shaft of which the cam is fixed, and the cartridges are radially located on the rim for test cans held on cartridges at atmospheric pressure, while the vacuum inside the cans is maintained by means of a bellows with a spring-loaded stem, characterized in that, in order to increase reliability The cans are sorted according to tightness, the bellows rods are provided with fingers, and on the way of their movement during rotation of the wheel, there are two cam segments that interact with the fingers, one of which serves to control the compression of the bellows before installing on the cartridges of the tested cans, cartridges of sealed cans and additional stretching of the bellows to hold the cans partially lost vacuum, and separated after separation from the cartridges of sealed cans. 2. The machine according to claim 1, characterized in that, in order to eliminate the influence of changes in atmospheric pressure on the operation of the machine, the second of the cam segments is made reversible in the radial direction. 3. Machine on PP. 1-2, characterized in that, in order to reduce the volume occupied by air in the cartridge, a body is provided therein, provided with an axial through channel. 4. Machine on PP. 1-3, characterized in that, in order to reduce the volume of air and the bellows, inside it is a solid disc.
