Spinning machine and method

Abstract

A textile machine that can comprise a first negative pressure point for producing a thread, a second negative pressure point for sucking in the thread and a negative pressure system which can be designed and arranged to be brought into a fluidic connection with the first negative pressure point. Alternatively, the first negative pressure system can be designed and arranged to be in a fluidic connection with the first negative pressure point. The textile machine can comprise a second negative pressure system that can be brought into a fluidic connection with the second negative pressure point. Alternatively, the second negative pressure system can be designed and arranged to be in fluidic connection with the second negative pressure point. A connection between the first negative pressure system and the second negative pressure system is designed such that the connection can be selectively established or interrupted.

1 . A textile machine comprising:
 at least one first negative pressure point for producing a thread;   at least one second negative pressure point for sucking in the thread;   at least one first negative pressure system that is designed and arranged in order to be brought into a fluidic connection with the at least one first negative pressure point or is designed and arranged in order to be in a fluidic connection with the at least one first negative pressure point; and   at least one second negative pressure system that is designed and arranged in order to be brought into a fluidic connection with the at least one second negative pressure point or is designed and arranged in order to be in a fluidic connection with the at least one second negative pressure point;   wherein a connection is formed between the first negative pressure system and the second negative pressure system in such a way that the connection can be selectively established or interrupted.   
     
     
         2 . The textile machine according to  claim 1 , wherein the at least one first negative pressure point comprises a spinning apparatus for producing the thread. 
     
     
         3 . The textile machine according to  claim 1 , wherein the at least one second negative pressure point for sucking in the thread comprises at least one of the following:
 a suction nozzle for picking up the thread from a take-up bobbin;   a thread storage nozzle for picking up the thread; and   a working element that can be subjected to negative pressure.   
     
     
         4 . The textile machine according to  claim 1 , wherein the connection between the at least one first negative pressure system and the at least one second negative pressure system is arranged in at least one of the following regions:
 a negative pressure source chamber;   a filter chamber; and   a negative pressure channel.   
     
     
         5 . The textile machine according to  claim 1 , wherein the connection between the at least one first negative pressure system and the at least one second negative pressure system can be adjusted. 
     
     
         6 . The textile machine according to  claim 1 , wherein the connection between the at least one first negative pressure system and the at least one second negative pressure system can be adjusted via at least one of the following:
 at least one control device; and   at least one frequency converter;   in each case designed and configured in order to control at least one negative pressure source.   
     
     
         7 . The textile machine according to  claim 1 , wherein the connection is designed and arranged in order to be automatically adjusted as a function of respective operating states of the at least one first negative pressure system and the at least one second negative pressure system. 
     
     
         8 . The textile machine according to  claim 1 , wherein the connection is designed and arranged in order to adjust a fluid flow by a fluid flow adjustment apparatus. 
     
     
         9 . A method for allocating negative pressure for the textile machine according to  claim 1 , comprising:
 actuating at least one fluid flow adjustment apparatus in order to adjust a fluid flow between the at least one first negative pressure system and the at least one second negative pressure system in order to adjust the connection between the at least one first negative pressure system and the at least one second negative pressure system.   
     
     
         10 . A control device, which is designed in order to carry out the method according to  claim 9  and/or is designed and configured for a textile machine comprising:
 at least one first negative pressure point for producing a thread; 
 at least one second negative pressure point for sucking in the thread; 
 at least one first negative pressure system that is designed and arranged in order to be brought into a fluidic connection with the at least one first negative pressure point or is designed and arranged in order to be in a fluidic connection with the at least one first negative pressure point; 
 at least one second negative pressure system that is designed and arranged in order to be brought into a fluidic connection with the at least one second negative pressure point or is designed and arranged in order to be in a fluidic connection with the at least one second negative pressure point; 
 wherein a connection is formed between the at least one first negative pressure system and the at least one second negative pressure system in such a way that the connection can be selectively established or interrupted. 
 
     
     
         11 . The textile machine according to  claim 1 , wherein the connection comprises a bypass connection.
