Method for operating a tubular-bag machine

Abstract

The invention relates to a method for operating a tubular-bag machine (01) having a film web (03) unwindable from a supply roll (02), a forming shoulder (04) for forming the film web (03) to a film tube (05), a film take-off unit (07) acting against the film tube (05) and serving to keep the film tube (05) moving, a longitudinal-sealing apparatus for sealing the film tube (05) along a longitudinal seam, a transverse-sealing apparatus (08) having transverse jaws (09) which move towards each other, transversally seal the film tube (05) and serve to produce transverse seams, a separator (11) for separating completed tubular bags (10) from the film tube (05), a metering module (13) for metering the filling material (12) being disposed upstream of the tubular-bag machine (01) and/or a processing module (14) for further processing the tubular bag being disposed downstream of the tubular-bag machine (01), and error messages of the tubular-bag machine (01) and/or the metering module (13) and/or the processing module (14) being able to be processed in the control (15) of the tubular-bag machine (01). The processing speed of the tubular-bag machine (01) is changed as a function of the error messages of the tubular-bag machine (01) and/or of the metering module (13) and/or of the processing module (14) received in the control (15) of the tubular-bag machine (01).

 characterized in that   the processing speed of the tubular-bag machine ( 01 ) is changed as a function of the error messages of the tubular-bag machine ( 01 ) and/or of the metering module ( 13 ) and/or of the processing module ( 14 ) received in the control ( 15 ) of the tubular-bag machine ( 01 ).   
     
     
         2 . The method according to  claim 1 ,
 characterized in that   the processing speed of the tubular-bag machine ( 01 ) is reduced by a predetermined number of cycles of change after receiving an error message.   
     
     
         3 . The method according to  claim 1 ,
 characterized in that   the different error messages are each assigned to a specific number of cycles of change.   
     
     
         4 . The method according to  claim 1 ,
 characterized in that   the processing speed of the tubular-bag machine ( 01 ) is increased to the original level after a predetermined observation time or a predetermined number of cycles for observation has ended.   
     
     
         5 . The method according to  claim 1 ,
 characterized in that   the error message signals the inclusion of filling material ( 12 ) in the sealing zone formed between the transverse jaws ( 09 ).   
     
     
         6 . The method according to  claim 1 ,
 characterized in that   the error message signals not meeting the sealing temperature in the sealing zone formed between the transverse jaws ( 09 ).   
     
     
         7 . The method according to  claim 1 ,
 characterized in that   the control of the tubular-bag machine ( 01 ) receives the error message from a weighing apparatus having at least one set of scales and being disposed upstream of the tubular-bag machine ( 01 ) for metering.   
     
     
         8 . The method according to  claim 7 ,
 characterized in that   the error signal signals an insufficient metering amount of the filling material in the upstream weighing apparatus.   
     
     
         9 . The method according to  claim 7 ,
 characterized in that   the error message signals an overfilling with filling material in at least one set of scales of the upstream weighing apparatus.   
     
     
         10 . The method according to  claim 1 ,
 characterized in that   the control of the tubular-bag machine ( 01 ) receives the error message from a repackaging apparatus disposed downstream of the tubular-bag machine ( 01 ) for repackaging.   
     
     
         11 . The method according to  claim 10 ,
 characterized in that   a cartoning machine or a final-packaging machine is used as a repackaging apparatus.
