Abstract

An apparatus for automated replacement of ring travelers on spinning or twisting rings is disclosed comprising generally a housing having two planar support members, parallel to each other. A lift-out device is pivotably supported in a first of the two planar members and a device for the attachment of a new ring traveler is supported in the second plane, parallel to the first plane. The devices function by guide systems, pivotable by eccentric cams, located on a common drive shaft to be able to move the two devices between an operational and an off position. A housing, containing the two devices, is mobile along a ring rail of a spinning machine. The lift-out device lifts out a ring traveler which is to be replaced from the spinning ring on the ring rail. The attachment device subsequently attaches a new ring traveler from a magazine rod onto the spinning ring. Because of the small distance in longitudinal direction between the unlatching and latching position of the ring rail, replacement of the ring traveler at the spinning ring can be accomplished in the same position of the apparatus. The magazine rod is continuously fed a new ring traveler from a coil upon which a string containing ring travelers is coiled.

Dependent claims

An apparatus for replacing ring travellers on spinning or twisting rings comprising:

a housing having two substantially parallel first and second walls defining substantially parallel first and second planes;
a lift-out device for lifting out a ring traveller, said lift-out device having:
a pin for supporting the ring traveller in a lift-out position thereof;
means for imparting a motion impulse to the ring traveller for positioning the ring traveller on said pin;
and
an actuatable clamping organ for retaining the ring traveller on said pin;
first motion links movably supported in said housing and connected with said lift-out device, said motion links being movable in said first plane between an operations position and an off position thereof;
a device for attaching a new ring traveller, said attaching device being movable in said second plane between an operational position and an off position thereof and including:
a ring traveller magazine containing a plurality of strung ring travellers;
means for feeding an individual ring traveller from said magazine and for retaining the individual ring traveller at an end of said magazine;
stop means cooperating with said magazine for retaining the individual ring traveller at said end;
and
second motion links movably supported in said housing and connected with said attaching device for moving said attaching device between operational and off positions thereof.
