A method for performing a batch change in an automatic cheese winder, which has many identical winding stations disposed in sections and a transportation system for supplying yarn-wound spinning cops to and removing empty unwound spinning cops from the winding stations. Transport trays for transporting spinning cops or empty tubes revolve within the transportation system, which has many different transport paths, among others transverse transport paths leading to the winding stations. The clearing away of an old batch of yarn is done section by section. Thus, from the transverse transport paths of one winding station section, spinning cop-carrying transport trays are discharged until such time as that section has been cleared out. The temporary storage of empty transport trays in the transverse transport paths of a cleared winding station section is already begun while adjacent winding station sections are still being cleared. When the automatic cheese winders are being filled with spinning cops from a new batch of yarn, at the same time one empty transport tray per transverse transport path is discharged out of the transverse transport paths, and the free spaces thus created on the transverse transport paths are filled uniformly via the storage path with transport trays that carry spinning cops with the new batch of yarn.

Method for operating an automatic cheese winder when changing batches

A method for operating an automatic cheese winder, having multiple winding stations (A, B, etc.) and a transportation system (,) for supplying the winding stations with spinning cops (,) and discharging them of empty tubes (,). The spinning cops are furnished by a preceding textile machine (,) having a spinning cop and empty tube transport device (,) communicating with the transportation system (,). The delivery of spinning cops to the winder (,) is continuously monitored by a sensor. A control device (,) of a tube monitor (,) assures that empty tube-equipped transport trays are kept on hand in the transportation system, and the tube monitor via the central control unit (,) initiates a controlled slow-down of the winder (,) into an energy-saving mode. Upon resumption of delivery of the spinning cops, the winder is accelerated from the energy-saving mode to an operating mode.

An automatic bobbin winder having a plurality of transport loops which have partially common transport tracks for bobbins is improved by the present invention wherein an electronic memory device is associated with the respective textile bobbin, as a carrier of product information. A monitoring apparatus for monitoring the success of the preparation of returned textile bobbins is provided at a first preparation device and is connected with a writing device for writing in the successful preparation into the memory device. A communication device for reading the information written in as the acknowledgement of successful preparation is provided at a second preparation device for textile bobbins to be fed to the bobbin winder. The communication device is connected with a control apparatus for the start-up of the second preparation device in the absence of the information acknowledging the successful preparation at the first preparation device.
