Method for producing a pallet-less packaging unit and a packaging unit produced according to the method

Abstract

A method for producing a pallet-less packaging unit has multiple packaging objects stacked to a stack of goods. The objects are stacked with a special layer that forms at least two encroachment areas for fork legs of a lift truck in at least one stack level. The special layer is first stacked on a normal layer larger than the special layer. The stack of goods is wrapped with its encroachment areas with a first film, the stack of goods that is wrapped on one side is turned around so the part of the stack of goods that has the special layer comes downwards and the stack of goods is wrapped with a second film that reaches up to the first film. In embodiments, second encroachment areas extend essentially at a right angle to first encroachment areas. The method provides a pallet-less packaging unit that can be handled more easily.

         4 . The method according to  claim 1 , wherein the packaging units that form the normal layer are formed with identical sizes. 
     
     
         5 . The method according to  claim 1 , wherein the normal layer is formed with five packaging units and the special layer with four packaging units. 
     
     
         6 . The method according to  claim 1 , wherein the packaging units that form the special layer are bags with a base area whose width is 440 mm+/−30 mm and whose length is 510 mm+/−30 mm. 
     
     
         7 . The method according to  claim 1 , wherein the special layer has a base area whose width (SB) is 880 mm+/−60 mm and whose length (SL) is 1020 mm+/−60 mm. 
     
     
         8 . The method according to  claim 1 , wherein the normal layer has a base area whose width (NB) is 1100 mm+/−60 mm and whose length (NL) is 1300 mm+/−60 mm. 
     
     
         9 . The method according to  claim 1 , wherein bags with different sizes are produced and filled in a bagging facility, which stacks to bags as packaging units to a stack of goods, and fed to a palleting device via a conveying track. 
     
     
         10 . The method according to  claim 9 , wherein the palleting device stacks the bags of the normal layer and the bags of the special layer at a palleting position. 
     
     
         11 . The method according to  claim 10 , wherein the palleting device stacks the bags of the normal layer at a first palleting position and that the bags of the special layer are laid via a laying device of the special layer. 
     
     
         12 . The method according to  claim 10 , wherein the bags of the normal layer and the bags of the special layer are made of the same film material by means of a form-fill-seal method. 
     
     
         13 . A method for producing a pallet-less packaging unit that comprises multiple packaging objects that are stacked to a stack of goods and in which the packaging objects are stacked in such a way that a special layer, which forms at least two encroachment areas for fork legs of a lift truck, is formed on at least one stack level, wherein the special layer is stacked at first to a normal layer that is larger in relation to said special layer,
 the stack of goods is wrapped with its encroachment areas with a first film;   the stack of goods that is wrapped on one side is turned around so that the part of the stack of goods that has the special layer comes downwards and that the stack of goods is wrapped with a second film that reaches up to the first film,   wherein, the packaging units that form the special layer are bags with a base area whose width (B) is 440 mm+/−30 mm and whose length (L) is 510 mm+/−30 mm,   the special layer has a base area whose width (SB) is 880 mm+/−60 mm and whose length (SL) is 1020 mm+/−60 mm, the normal layer has a base area whose width (NB) is 1100 mm+/−60 mm and whose length (NL) is 1300 mm+/−60 mm.   
     
     
         14 . The method according to  claim 13 , wherein bags with different sizes are produced and filled in a bagging facility, which stacks to bags as packaging units to a stack of goods, and fed to a palleting device via a conveying track. 
     
     
         15 . The method according to  claim 14 , wherein the palleting device stacks the bags of the normal layer and the bags of the special layer at a palleting position.
