Abstract
Method and device for preparing a ring spinning frame for automatic coil changing, which includes controlling a movable automatic servicing device for the spinning operation and a movable automatic servicing device for changing coils with a central automatic spinning control which controls the spinning processes of all spinning units of the machine so that both mentioned servicing devices are placed in readiness at the machine end of the ring spinning frame when the spinning process is completed.
Claims9
Method for preparing a ring spinning frame for automatic coil changing, which comprises issuing a command from a central automatic spinning control before the end of the spinning operation to at least one of a movable automatic servicing device for the spinning operation and a movable automatic servicing device for changing coils which has not yet reached the machine end of the ring spinning frame to move to the machine end, moving the at least one servicing device to the machine end, and connecting the servicing devices together at the machine end no later than the arrival of the at least one servicing device at the machine end, so that both mentioned servicing devices are placed in readiness at the machine end of the ring spinning frame when the spinning process is completed.
Apparatus for preparing a ring spinning frame of a spinning machine for automatic coil changing, comprising a movable automatic servicing device for the spinning operation, a movable automatic servicing device for changing coils, central automatic means for controlling spinning at all spinning units of the machine, a machine end of the spinning frame, a timer connected to said central automatic controlling means being sequentially movable between at least a first time mark and a second subsequent time mark at which the spinning operation is ended, and means connected to said central automatic controlling means for initiating movement toward said machine end at said first time mark by at least one of said servicing devices which has not yet reached said machine end and for completing movement to the machine end substantially at said second time mark.
