ABSTRACT:
A method of automatically removing takeup packages of a two-sided textile machine, in particular a winding, spinning, or twisting machine with random doff by at least one automated handling device traveling along the longitudinal sides of the machine and of depositing the removed takeup packages on a conveyor belt common to both machine sides, which is arranged in the longitudinal center of the machine and adapted for a stepwise forward movement, and which is followed by a buffer zone. The automated handling device checks at each position of a due package doff and before delivering a takeup package to the conveyor belt, whether the belt is vacant at this position or already occupied by a takeup package. In the event of an occupancy, the automated handling device supplies to the conveyor belt drive a control signal, by which the conveyor belt is stepwise advanced until a vacant space on the conveyor belt arrives at this position. As soon as the buffer zone is completely filled with takeup packages, an alarm signal is emitted to a superposed monitoring device, which triggers a clearance of the conveyor belt. The present method allows to achieve a utilization factor of more than 50% of the conveyor belt.
