Method and device for transporting packaging bags for liquid or pasty products having a weld-in closure

Abstract

For transporting packaging bags ( 1 ), e.g. from a production facility to further processing, e.g. for being filled, the packaging bags ( 1 ) are connected to at least one flexible strip ( 13, 14 ). To this end, the packaging bags ( 1 ) are delivered one after another to a loading device where they are supported by their weld-in closures ( 4 ) on supporting and guiding means ( 9 ) and moved along these supporting and guiding means ( 9; 10 ). On the latter, the weld-in closures are connected to the strip ( 13, 14 ), e.g. by welding.

1 . Method for transporting packaging bags for liquid or pasty products having a weld-in closure with a pouring opening where a number of packaging bags are connected by their weld-in closures to at least one flexible strip to form a transport unit, wherein the packaging bags are delivered to a loading device where they are supported by their weld-in closures on supporting and guiding means and moved along these supporting and guiding means, and in that at least one strip is guided along these supporting and guiding means and connected there to the weld-in closures. 
     
     
         2 . Method according to  claim 1 , wherein the weld-in closures are connected to the at least one strip in such a manner that the pouring opening is freely accessible, and the pouring opening and the portions of the packaging bag opposite the latter are located on opposite sides relative to the plane of the at least one strip. 
     
     
         3 . Method according to  claim 1 , wherein the weld-in closures are connected to the at least one strip; in a frictional or positive manner in that a portion of the weld-in closure adjacent to its pouring opening is pushed through the at least one strip. 
     
     
         4 . Device according to  claim 1 , wherein the weld-in closures are materially connected to the at least one strip in that a portion of the weld-in closure adjacent to its pouring opening is welded or bonded to the at least one strip. 
     
     
         5 . Method according to  claim 1 , wherein the at least one strip comprises at least one layer of a plastic film, preferably of polyethylene, polyethylene terephthalate, polypropylene, or polyamide. 
     
     
         6 . Method according to  claim 1 , wherein the at least one strip has reinforcing means arranged therein, preferably in the form of longitudinal ridges, edge reinforcements, or chambers capable of being pressurized by a fluid. 
     
     
         7 . Method according to  claim 1 , wherein the weld-in closures are connected to two parallelly guided strips. 
     
     
         8 . Method according to  claim 7 , wherein weld-in closures are supported on the supporting and guiding means by guiding flanges or guiding grooves arranged on the former. 
     
     
         9 . Method according to  claim 1 , wherein transport units each comprising at least a hundred packaging bags are laid down in logistics containers in layers, for which purpose guiding means of the placement device and of the logistics containers are preferably moved relative to each other. 
     
     
         10 . Device for transporting packaging bags for liquid or pasty products having a weld-in closure with a pouring opening, comprising a loading device for connecting at least one flexible strip to the weld-in closures of a number of packaging bags to form a transport unit, wherein the loading device comprises supporting and guiding means for the weld-in closures. 
     
     
         11 . Device according to  claim 10 , wherein the supporting and guiding means consist of two parallel rails between which a gap for the passage of a portion of the weld-in closures is provided. 
     
     
         12 . Device according to  claim 10 , wherein the loading device includes welding means for welding the at least one flexible strip to the weld-in closures. 
     
     
         13 . Device according to  claim 10 , further comprising a placement device for placing transport units in logistics containers, which is preferably provided with guiding means for the transport units and with means for moving the guiding means and the logistics containers relative to each other. 
     
     
         14 . Device according to  claim 13 , further comprising a pickup device for picking up transport units laid down in logistics containers, which is preferably provided with guiding means for the transport units and with means for moving the guiding means and the logistics containers relative to each other. 
     
     
         15 . Device according to  claim 10 , further comprising a separating device for separating the weld-in closures from the at least one flexible strip.
