Magazine for Temporarily Storing Flat-Folded and Upright Standing Package Sleeves for Supplying a Downstream Filling Machine with the Package Sleeves

Abstract

A magazine for temporarily storing at least one package sleeve group having a plurality of flat-folded and upright standing package sleeves and for equipping an unfolding device for the package sleeves following the magazine is represented and described, comprising a supply side supplying the package sleeves, a removal side arranged in a transport direction of the package sleeve group behind the supply side and at least one transport unit movable forwards and backwards along the transport direction to transport the package sleeve group from the supply side to the removal side. In order to ensure the uniform supply of the subsequent unfolding device and therefore to increase the productivity of the subsequent filling machine and also to achieve a constructively simple and simultaneously cost-effective configuration of the magazine, which can also be flexibly applied to different package sleeve sizes, it is proposed that the transport unit has at least two slide elements, arranged opposite one another and in each case resting at least partially on one side of the package sleeves, to align the package sleeves.

1 . A magazine for temporarily storing at least one package sleeve group having a plurality of flat-folded and upright standing package sleeves and for equipping an unfolding device for the package sleeves following the magazine, comprising:
 a supply side supplying the package sleeves,   a removal side arranged in a transport direction of the package sleeve group behind the supply side and   at least one transport unit movable forwards and backwards along the transport direction to transport the package sleeve group from the supply side to the removal side,   wherein the transport unit has at least two slide elements, arranged opposite one another and in each case resting at least partially on one side of the package sleeves, to align the package sleeves,   characterised in that   the slide elements in each case have a bearing region running substantially parallel to the transport direction and an alignment region tapering in the transport direction, wherein a distance, running perpendicular to the transport direction, of the slide elements, arranged opposite one another, decreases from the alignment region to the bearing region.   
     
     
         2 . Magazine according to  claim 1 ,
 characterised in that   the slide elements are formed so as to be interchangeable.   
     
     
         3 . (canceled) 
     
     
         4 . The magazine according to  claim 1 ,
 characterised in that   a slide rod running substantially parallel to the transport direction is provided and in that the transport unit has a slide carriage movable forwards and backwards on the slide rod.   
     
     
         5 . The magazine according to  claim 1 ,
 characterised in that   the transport unit has at least two feed doors, wherein the feed doors rest in a closed state at the rear side on the last package sleeve of the package sleeve group to be transported and are configured to push the package sleeve group to be transported in the transport direction and wherein the feed doors are configured in an opened state to enable a supply of package sleeves to be transported between the feed doors.   
     
     
         6 . The magazine according to  claim 5 ,
 characterised in that   the feed doors are pivotable from the closed state into the opened state and back.   
     
     
         7 . The magazine according to  claim 6 ,
 characterised in that   the transport unit has, for each feed door, a spring forcing the feed doors into the closed state by means of a restoring force.   
     
     
         8 . The magazine according to  claim 1 ,
 characterised in that   the transport unit has an access opening formed by a U-shaped frame arranged in the transport direction before the package sleeve group to be transported for the supply of package sleeves to be transported.   
     
     
         9 . The magazine according to  claim 8 ,
 characterised in that   the feed doors are arranged in the closed state resting on an end side, pointing in the transport direction, of a horizontal support of the U-shaped frame.   
     
     
         10 . The magazine according to  claim 9 ,
 characterised in that   the horizontal support of the U-shaped frame has a slide element, pointing towards the bottom in the direction of the package sleeves, to compensate for a vertical height offset of successive package sleeves.   
     
     
         11 . The magazine according to  claim 1 ,
 characterised in that   in each case a stop stopping the transport unit after a maximum forward movement in the transport direction is provided on the removal side for each transport unit.   
     
     
         12 . The magazine according to  claim 11 ,
 characterised in that   the stop is arranged such that the transport unit impacts against the stop to stop after a maximum forward movement in the transport direction by means of the slide carriage.   
     
     
         13 . The magazine according to  claim 1 ,
 characterised in that   in each case at least one slide rail running from the supply side to the removal side along the transport direction is provided for each transport unit as a support for the package sleeves to be transported.   
     
     
         14 . The magazine according to  claim 1 ,
 characterised in that   in each case two lateral boundary rails arranged opposite one another and in each case on one side of the package sleeves can be provided for each transport unit.   
     
     
         15 . The magazine according to  claim 14 ,
 characterised in that   in each case the bearing region of the slide elements has an oversized portion, compared to the corresponding lateral boundary rail, said oversized portion pointing perpendicular to the transport direction and in the direction of the package sleeves.   
     
     
         16 . The magazine according to  claim 14 ,
 characterised in that   the lateral boundary rails have, on the supply side, a tapering region running in the transport direction.   
     
     
         17 . The magazine according to  claim 1 ,
 characterised in that   in each case a clamp device is provided on the supply side for each transport unit, wherein the clamp device has a retaining hook engaging a stopper provided on the transport unit.   
     
     
         18 . The magazine according to  claim 17 ,
 characterised in that   the stopper is arranged on the slide carriage of the transport unit.
