Device for checking cylindrical bodies, especially tubes of open-end

Abstract

A device for checking cylindrical bodies, especially the tubes of open-end spinning machines transported along a feed path from a tube container to the distribution mechanism of the tubes on the machine, for example, by means of a chain conveyor with feed blades and with a cyclical intermittent motion. The above includes an auxiliary container for discarded tubes situated over the tube container near the feed path of the feed blades and oriented with its inlet aperture towards the feed path. The arrangement includes a centering device mounted transversely with respect to the feed path of the tubes at the location where the blades of the chain conveyor are cyclically stopped. The centering device is disposed along the axis of the tube which is transported to it. The centering device is provided with a drive for imparting rotary motion to the centered tube. An inspection device is provided which comprises a pair of contact members which are operatively connected to feelers that are, together with a switch mounted at the end position of the centering device, connected with an actuating member arranged so as to shift the tubes identified as damaged out of the feed path and towards an inlet aperture of the auxiliary container provided for discarded tubes.
