Method for operating a semi-automatic or fully automatic, cross-wound package-manufacturing spinning machine

Abstract

A method is provided for operating a semi-automatic or fully automatic cross-wound package-manufacturing spinning machine that has a plurality of identical, adjacently arranged, and at least partially autonomous workstations. Each of the workstations has a spinning device for manufacturing a thread and a winding device including a package holder for winding the thread onto a cross-wound package. Once an end of a lot being processed at one of the workstations has been reached, the workstation is stopped. A requirement that at least one manual service action must be carried out at the workstation before a lot change at the workstation is displayed at the workstation.

         16 . A method for operating a semi-automatic or fully automatic cross-wound package-manufacturing spinning machine that has a plurality of identical, adjacently arranged, and at least partially autonomous workstations, wherein each of the workstations has a spinning device for manufacturing a thread and a winding device including a package holder for winding the thread onto a cross-wound package, the method comprising:
 once an end of a lot of one of the workstations has been reached, stopping the workstation; and   displaying at the workstation a requirement that at least one manual service action must be carried out at the workstation.   
     
     
         17 . The method of  claim 16 , further comprising displaying at the workstation an indication of a current lot being processed at the workstation. 
     
     
         18 . The method of  claim 16 , wherein the requirement that at least one manual service action be carried out is indicated by an occupancy condition of the package holder or by an occupancy condition of a supply position for empty tubes at the workstation. 
     
     
         19 . The method of  claim 16 , wherein the cross-wound package of a current lot processed at the workstation is automatically withdrawn and the requirement that at least one manual service action be carried out is indicated by the package holder at the work station being empty. 
     
     
         20 . The method of  claim 16 , wherein the cross-wound package of a current lot processed at the workstation is automatically withdrawn and the requirement that at least one manual service action be carried out is indicated by an empty tube at the workstation. 
     
     
         21 . The method of  claim 16 , wherein the cross-wound package of a current lot processed at the workstation is automatically withdrawn and the requirement that at least one manual service action be carried out is indicated by incorrectly loading the package holder at the work station. 
     
     
         22 . The method of  claim 16 , wherein requirement that at least one manual service action be carried out is indicated by an optical display element at the workstation that generates any combination of a graphical, coded, lighted signal. 
     
     
         23 . The method of  claim 22 , wherein the requirement that at least one manual service action be carried out is indicated by an icon presented on the optical display element. 
     
     
         24 . The method of  claim 22 , wherein the requirement that at least one manual service action be carried out is indicated by the optical display element after actuation of an input device associated with the optical display element. 
     
     
         25 . The method of  claim 22 , wherein an operator confirms that the manual service action has been carried out by actuation of a button associated with the optical display element, and a further manual service action to be carried out is then indicated by the optical display element. 
     
     
         26 . The method of  claim 25 , wherein the manual service action and the further manual service action are displayed as a text display or as an icon on the optical display element. 
     
     
         27 . The method of  claim 25 , wherein after the operator confirms that the manual service action and the further manual service action have been carried out, a new lot is started at the workstation. 
     
     
         28 . The method of  claim 16 , wherein the manual service action to be carried out is one or both of: a replacement of spinning components; and a replacement of fiber material. 
     
     
         29 . The method of  claim 16 , further comprising displaying at the workstation an indication of a current lot being processed at the workstation and a different indication of a new lot to be processed after a lot change at the workstation. 
     
     
         30 . A semi-automatic or fully automatic cross-wound package-manufacturing spinning machine, comprising:
 a plurality of identical, adjacently arranged, and at least partially autonomous workstations;   each of the workstations comprising a spinning device and a winding device, the winding device comprising a package holder for winding a thread onto a cross-wound package;   a control device and a display element;   and wherein the control device and the display element are configured to carry out the method according to  claim 16 .
