Apparatus for manufacturing packaging units

Abstract

The invention relates to an apparatus for manufacturing packaging units in a tubular bag forming, filling and sealing machine, having a horizontal conveyor installation for transferring separated products ( 14 ) to a portioning appliance ( 15 ) for manufacturing portion units ( 12 ) with a defined arrangement and number of products, and having a vertical conveyor installation ( 22 ) for conveying the portion units, which are enveloped by a film web ( 11 ), to a separating appliance for separating the packaging units, wherein the vertical conveyor installation has two parallel strap conveyors ( 34, 35 ), wherein a film take-off appliance ( 36 ), which delimits the conveying channel laterally, is arranged so as to be parallel to the strap conveyors, wherein the vertical conveyor installation ( 22 ) has a conveying channel setting appliance for setting the distance b between the conveying sides arranged so as to be opposed to each other and pertaining to the conveying straps, and wherein the film take-off appliance ( 36 ) is provided with a setting appliance for setting the distance a 3 between the film take-off appliance and the vertical conveyor installation.

1 . An apparatus for manufacturing packaging units in a tubular bag forming, filling and sealing machine, having a horizontal conveyor installation for transferring separated products to a portioning appliance for manufacturing portion units with a defined arrangement and number of products, said apparatus comprising:
 a vertical conveyor installation for conveying portion units enveloped by a film web, wherein the vertical conveyor installation has two parallel strap conveyors including circulating conveying straps with conveying sides arranged so as to be opposed to each other, said conveying straps defining a conveying channel conveying the portion units enveloped by the film web;   a film take-off appliance laterally delimiting the conveying channel is arranged so as to be parallel to the strap conveyors, said take-off appliance grasping film edges of said film web enveloping the portion units, said film edges being brought together in a film web deflecting appliance;   a conveying channel setting appliance setting a distance b between the conveying sides; and   a film take-off setting appliance setting a distance a 3  between the film take-off appliance and the vertical conveyor installation.   
     
     
         2 . The apparatus according to  claim 1 , in which the conveying channel setting appliance has two axial infeed appliances arranged at a base frame of the vertical conveyor installation, each of said axial infeed appliances acts on a strap conveyor, and defines an infeed axis oriented so as to be parallel to the base frame. 
     
     
         3 . The apparatus according to  claim 2 , in which the axial infeed appliances, for altering the distance of the strap conveyors, adjust the distance a 1  between driving axles of the strap conveyors. 
     
     
         4 . The apparatus according to  claim 2 , in which the film take-off setting appliance adjusts a distance between take-off rollers of the film take-off appliance and the base frame of the vertical conveyor installation. 
     
     
         5 . The apparatus according to  claim 4 , in which the film take-off setting appliance has length adjustable brackets connected to a regulating frame and arranged at the base frame, said brackets are provided with a take-off roller at a free end of each bracket, wherein a distance between the regulating frame and the base frame is adjustable by at least one of the axial infeed appliances. 
     
     
         6 . The apparatus according to  claim 5 , in which the take-off rollers of the film take-off appliance are provided with a hitch setting appliance ( 87 ), which makes it possible to set an angle of hitch α of roller axes of the take-off rollers relative to a horizontal level. 
     
     
         7 . The apparatus according to  claim 6 , in which the hitch setting appliance has an actuator arranged at the base frame and connected via a regulating shaft to a pivoting appliance arranged at the take-off rollers and pivoting the roller axis. 
     
     
         8 . The apparatus according to  claim 7 , in which the regulating shaft is a cardan shaft.
