Apparatus for producing bag packages filled with a product

Abstract

An apparatus for producing bag packages filled with a product has a tubular-bag-making machine, in which the bag packages are produced. After that, the bag packages reach a weighing device and from there they reach a conveyor system, which delivers the bag packages to downstream evacuating and closing systems. Because the weighing device is disposed between the tubular-bag-making machine and the conveyor system, it is possible to ascertain the current weight of a bag package that has just been filled, and if the weight deviates from a rated filling weight, it is possible to trigger the metering device of the tubular-bag-making machine in such a way that the next bag package filled contains the rated filling quantity again.

1 . In an apparatus ( 10 ) for producing bag packages ( 1 ) that are filled with a product, having a bag-producing apparatus embodied as a tubular-bag-making machine ( 11 ), a weighing device ( 30 ) for weighing the filled bag packages ( 1 ), and a conveyor system ( 23 ), which has receptacles for the bag packages ( 1 ) and which receive the bag packages ( 1 ) at equal spacings from one another and delivers them to downstream processing stations, in particular evacuation and closing stations, the improvement wherein the weighing device ( 30 ) is disposed between the tubular-bag-making machine ( 11 ) and the conveyor system ( 23 ).  
   
   
       2 . The apparatus in accordance with  claim 1 , wherein the tubular-bag-making machine ( 11 ) comprises a transverse seam cutter ( 15 ), and wherein the weighing device ( 30 ) is disposed below the transverse seam cutter ( 15 ), the weighing device ( 30 ) includes a weighing cup ( 31 ) having a cross section for receiving a bag package ( 1 ) aligned with the bag package ( 1 ) in the tubular-bag-making machine ( 11 ).  
   
   
       3 . The apparatus in accordance with  claim 1 , wherein the weighing cup ( 31 ) has a movable bottom ( 36 ,  37 ) that uncovers the receiving cross section, and wherein the receiving cross section is aligned with the receptacles of the conveyor system ( 23 ).  
   
   
       4 . The apparatus in accordance with  claim 2 , wherein the weighing cup ( 31 ), as a format-dependent component, is replaceably secured to a weighing block ( 34 ).  
   
   
       5 . The apparatus in accordance with  claim 3 , wherein the weighing cup ( 31 ), as a format-dependent component, is replaceably secured to a weighing block ( 34 ).  
   
   
       6 . The apparatus in accordance with  claim 1 , wherein the weighing device ( 30 ) and the tubular-bag-making machine ( 11 ) are coupled by means of a control unit ( 20 ) in such a way that if underfilling or overfilling of a bag package ( 1 ) occurs, the control unit ( 20 ) delivers a correspondingly corrected new metering value, as a new rated value, to the metering device ( 18 ) of the tubular-bag-making machine ( 11 ).  
   
   
       7 . The apparatus in accordance with  claim 2 , wherein the weighing device ( 30 ) and the tubular-bag-making machine ( 11 ) are coupled by means of a control unit ( 20 ) in such a way that if underfilling or overfilling of a bag package ( 1 ) occurs, the control unit ( 20 ) delivers a correspondingly corrected new metering value, as a new rated value, to the metering device ( 18 ) of the tubular-bag-making machine ( 11 ).  
   
   
       8 . The apparatus in accordance with  claim 3 , wherein the weighing device ( 30 ) and the tubular-bag-making machine ( 11 ) are coupled by means of a control unit ( 20 ) in such a way that if underfilling or overfilling of a bag package ( 1 ) occurs, the control unit ( 20 ) delivers a correspondingly corrected new metering value, as a new rated value, to the metering device ( 18 ) of the tubular-bag-making machine ( 11 ).  
   
   
       9 . The apparatus in accordance with  claim 4 , wherein the weighing device ( 30 ) and the tubular-bag-making machine ( 11 ) are coupled by means of a control unit ( 20 ) in such a way that if underfilling or overfilling of a bag package ( 1 ), occurs, the control unit ( 20 ) delivers a correspondingly corrected new metering value, as a new rated value, to the metering device ( 18 ) of the tubular-bag-making machine ( 11 ).  
   
   
       10 . The apparatus in accordance with  claim 5 , wherein the weighing device ( 30 ) and the tubular-bag-making machine ( 11 ) are coupled by means of a control unit ( 20 ) in such a way that if underfilling or overfilling of a bag package ( 1 ) occurs, the control unit ( 20 ) delivers a correspondingly corrected new metering value, as a new rated value, to the metering device ( 18 ) of the tubular-bag-making machine ( 11 ).
