Film web deflecting device and device for manufacturing packaging units comprising a film web deflecting device

Abstract

The invention relates to a film web deflecting device ( 26 ) for a device for manufacturing packaging units, having a vertical enveloping axis ( 27 ). The device has an inlet opening ( 28 ), which is delimited by two molding shoulders, and a film edge guide slot on the lower end of the device laterally offset with respect to the enveloping axis. Opposing shoulder edges of the molding shoulders define a passage gap for the passage of portion stops after a portion unit has been transferred to a vertical conveyor ( 22 ), which receives the portion unit together with the film web on the periphery of the portion unit. Each of the shoulder edges has a guide ridge, said guide ridges defining a guide plane which is inclined relative to the enveloping axis, thereby forming a guide angle α, and extends from the inlet opening in the direction of the film edge guide slot.

1 . A film web deflecting device for a device for manufacturing packaging units, which have a portion unit being enveloped into a film web, having a film web conveyor for conveying a film web along a horizontal conveying track portion and along a vertical conveying track portion, wherein the film web deflecting device, for diverting the film web from the horizontal conveying track portion into the vertical conveying track portion and for forming a film envelope for a portion unit being supplied to the vertical conveying track portion and being received between portion stops, comprising:
 two molding shoulders;   an inlet opening proximal upper ends of the molding shoulders on a vertical enveloping axis, said inlet opening being delimited by the two molding shoulders;   a film edge guide slot proximal lower ends of the molding shoulders and laterally offset with respect to the enveloping axis;   opposing shoulder edges of the molding shoulders defining a passage gap for the passage of the portion stops after the portion unit has been transferred to a vertical conveyor, which receives the portion unit together with the film web on a periphery of the portion unit; and   a guide ridge on each shoulder edge of each molding shoulder, said guide ridges defining a guide plane inclined relative to the enveloping axis, thereby forming a guide angle α, and extending from the inlet opening in the direction of the film edge guide slot.   
     
     
         2 . The film web deflecting device according to  claim 1 , in which guide ridge portions of the guide ridges are inclined with respect to one another, thereby forming an angle β, in such a manner that the guide ridges converge in the shape of a V in the direction of the film edge guide slot. 
     
     
         3 . The film web deflecting device according to  claim 1 , in which the guide ridges of the molding shoulders extend from the inlet opening towards the film edge guide slot. 
     
     
         4 . The film web deflecting device according to  claims 1 , in which the guide ridges are formed by surface edges of guide flanks of the molding shoulders and form abutment faces for film edges of the film web. 
     
     
         5 . The film web deflecting device according to  claims 1 , in which the molding shoulders are connected to each other via a collar piece, in such a manner that the inlet opening is closed towards the horizontal conveying track portion and the collar piece forms a guide flank for the film web, which flank ascends towards the inlet opening. 
     
     
         6 . The film web deflecting device according to  claim 1 , in which the molding shoulders are formed independently of each other, in such a manner that the inlet opening has a collar gap towards the horizontal conveying track portion and the molding shoulders form a guide flank for the film web descending towards the inlet opening and being arranged in a common guide plane with a guide face of a guide means that bridges the collar gap. 
     
     
         7 . The film web deflecting device according to  claim 1 , in which the film edge guide slot, as viewed in the direction of the enveloping axis, is arranged so as to be diametrically opposed to the collar piece or to the guide means that bridges the collar gap. 
     
     
         8 . A device for manufacturing packaging units, which have a portion unit being enveloped into a film web, having a film web conveyor according to  claim 1  for conveying a film web along a horizontal conveying track portion and along a vertical conveying track portion, a portion conveyor for conveying the portion units, a film web deflecting device for deflecting the film web from the horizontal conveying track portion into the vertical conveying track portion and for forming a film envelope for the portion units being supplied to the vertical conveying track portion and being received between portion stops, and having a vertical conveyor, which receives the portion units together with the film web on the periphery.
