US 3,934,716 A · Orientation alignment apparatus for yarn cops being supplied to textile machines

Abstract

To provide yarn cops to textile machines in predetermined, uniform alignment and orientation of the yarn cops, typically to supply yarn cops to spooling or spinning machines, the diameter of the core ends of the yarn cops is sensed and a difference signal obtained. This difference signal is stored, mechanically or electrically and, when a cop is required to be fed to the spinning machine, the stored difference signal is transferred to an orientation alignment apparatus, typically a pair of pins which retain the cop in horizontal position and, upon withdrawal of a selected one of the pins, permit the cop to drop into a delivery chute, selectively, with the selected end first, to deliver the cop in properly oriented alignment to the textile machine, that is, typically to the spooling or spinning machine.

Dependent claims

Apparatus for coordinating the end-for-end orientation of spinning cops (14) for transport with proper end orientation to a textile machine having

a transport means (15, 35) transporting spinning cops with random end-for-end orientation, and orientation means (46, 46';
87, 87') to orient the cops to have a predetermined end-for-end orientation and to deliver the oriented, aligned cops to the textile machine,
comprising
spaced movable measuring means (21, 22;
21', 22';
31) located in the transport path of the cops engaging the end portions of the cops to measure the diameters thereof;
means coupled to the measuring means to provide a measuring result signal representative of the difference of the diameters, as measured, thereof;
and control signal generating means (63-69;
P, 91) applying said measuring result signal to the orientation means to effect delivery of a cop, in oriented alignment upon command of said control signal.

Apparatus for orienting spinning cops (14) end-for-end to have uniform orientation, and for transporting the spinning cops with uniform orientation to textile machines comprising

transport means (15, 35) transporting spinning cops with random end-for-end orientation;
two pairs of movable jaws (21, 22;
21', 22') located in the path of the cops and engaging respective ends of the cops;
a parallelogram linkage (210, 220;
210', 220') supporting said jaws and link means (25, 26, 27;
25', 26', 27') linking the jaws of each pair;
a difference lever (29) connected to the link means and changing position as determined by the relative spacing between the pairs of measuring jaws, and by its position providing an output signal representative of which one of the pairs of jaws are spaced farther apart than the other;
an orientation device (40, 46, 46';
40, 87, 87') including a position storage means (55, 51;
90, 89) and spaced, selectively movable cop support means (46, 46';
87, 87') in the transport path of the cops;
and signal transfer means (31) connected to the difference lever (29) and to the orientation device (40, 46, 46';
40, 87, 87') to transfer the position signal representative of the particular position of the difference lever to the orientation device and to selectively control the cop support means for withdrawal of support from a cop at either, selective, spaced position and thereby orient said cop.
