US Patent:

41931688, Mar 18, 1980

Filed:

Dec 7, 1977

Appl. No.:

5/858105

Inventors:

James H. Burnett - Greenville SC

International Classification:

D01G 3100

US Classification:

19 025

Abstract:

A stop motion apparatus is disclosed for disengaging a drive motion on a carding machine in response to the detection of a desired operating condition wherein the carding machine is of the type having motorized drive means for imparting a drive motion to the carding machine when engaged and actuator means for selectively enaging or disengaging the drive motion. The stop motion apparatus includes a base for attachment to the carding machine and a pivotable arm assembly carried by the base. A linkage assembly connects the pivotable arm assembly to the actuator means of the carding machine. The pivotable arm assembly has a first position in which the actuator means disengages the drive stopping the carding machine and a second position in which the actuator means engages the card drive. A unique cam-lock assembly is provided for locking the pivotal arm assembly in the second position maintaining the drive motion engaged, and a release mechanism is provided for releasing the cam lock assembly allowing the pivotable arm assembly to move to its first position. Various condition responsive devices are disclosed for detecting a desired condition on the carding machine and actuating the release mechanism.

Abstract:

A mechanical foreign object detector upstream from the feed roll of a carding machine faithfully detects minute hard objects in the lap which could damage the lickerin or other components of the card. Spring-loaded detector pins penetrate through the lap and contact foreign objects on an apertured plate beneath the lap. Such pins rise and contact a wire connected in a stop motion circuit which immediately stops the operation of the doffer and the feed roll before any damage can occur. A visual and/or audible indicator alerts the operator to the presence of a foreign object or objects which the operator removes by hand before restarting the card by operation of a key-operated reset switch in the circuit. The mechanical detector apparatus includes a power drive which is synchronized with the operation of the feed roll of the card.
