SU95654A1 - A device for controlling the tightness of a capping filled glass and tin cans - Google Patents

Description

Devices are known for monitoring the tightness of capping of filled glass and rigid cans, based on the method of determining the leakage of cans by the deflection of their lids under the influence of compressed air that is injected into the control chamber. However, they have sushi, natural flaws.

The proposed device allows to increase the accuracy of control and to test for tightness of different in height cans. The camcorder device is made of two-in-each cylinders — spring-loaded movable and stationary — separated by an elastic gasket and equipped from above with a descending electromagnet, designed to increase the boom of the flap, during the process of controlling the moving contact of the electrical signal device associated with reject mechanism.

FIG. 1 shows the proposed device; in fig. Two-part control tightness of rigid cans.

The device is made in the form of a chamber consisting of two cylinders 1 and 2 entering one another, of which cylinder 2 is movable and, by means of a gasket 3 tightly pressed by springs 4, makes it possible to seal the lateral surface of the chamber regardless of the height of the cans 5. The chamber equipped with an electromagnet 6, designed to increase the boom of the lid deflection in the can 5, in the process of monitoring the actuating contact 7 of the electrical, signaling device 8 connected to the rejecting mechanism (in not shown anymore).

Bank 5 is installed on cartridge 8 and introduced into the chamber. The lid of the can meets an electromagnet 6 and lifts it up. Thus, the imposition of an electromagnet 6 for each can is fixed

its edges. After the can is introduced into the chamber, the side cavity is sealed by the presence of a gasket 10 and a second gasket located on the cartridge 9. The chamber is sealed and compressed air of about 1 atm pressure is fed into the chamber through it. In the event of a leak in the can, air enters the can, causing the pressure inside the can to rise. Experience shows that to bulge the middle part of the glass can lid in the presence of an electromagnet, an excess pressure of about 15 mm Hg is sufficient. Art.

The buckling of the cover causes the rise (approximately 1.5 mm) of the movable contact 7, which, reaching the device 8, closes the electrical circuit. Upon arrival, the current in the electrical circuit gives a primary impulse, which is amplified and transmitted to the rejecting mechanism. The deflection of the can lid in the event of its leakage can also be fixed by means of an inductive sensor. When testing the cans of the support And the magnet 12 rests on the edge of the cover 13 at the fold of the can. The gasket on the cartridge 9 for rigid cans has the shape of a ring (at the end of the chamber cylinder).
