Packaging device and packaging method

Abstract

A packaging device ( 2 ) and a packaging method are for highly compressed bales ( 3 ) on a baling press ( 1 ). The packaging device ( 2 ) has a supply device ( 9 ) for a web-shaped packaging material ( 8 ) and a wrapping device ( 10 ) for attaching an annularly surrounding wrapping web ( 7 ) on the free side surfaces ( 32 ) of the compressed bale ( 3 ) which is held between compression rams ( 31 ). The wrapping device ( 10 ) is arranged with a transport device ( 20 ) movably relative to the compressed bale ( 3 ). The supply device ( 9 ) is arranged in a spatially and kinematically separate manner from the wrapping device ( 10 ), in particular in a stationary manner.

1 . A packaging device for highly compressed bales on a baling press, the packaging device comprising:
 a supply device for supplying a film web packaging material;   a wrapping apparatus for applying an annular surrounding film sleeve, to free lateral faces of the compressed bale held between press rams;   a transport means for moving the wrapping apparatus; and   a web guide for feeding the packaging material, wherein:   the wrapping apparatus is arranged so as to be movable by way of the transport means relative to the compressed bale;   the supply device is arranged separated spatially and kinematically from the wrapping apparatus;   the supply device is arranged stationarily;   the supply device comprises a web supply receptacle for a coil web supply, and the web guide feeds the packaging material to the wrapping apparatus; and   the receptacle and the web supply are arranged at a gap distance from the held compressed bale, wherein the web guide bridges the gap distance.   
     
     
         2 - 4 . (canceled) 
     
     
         5 . The packaging device as claimed in  claim 1 , wherein the supply device has at least one further receptacle for a replacement coil web supply. 
     
     
         6 . The packaging device as claimed in  claim 1 , wherein the receptacle and the web guide are arranged in a lying manner. 
     
     
         7 . The packaging device as claimed in  claim 1 , wherein the web guide has a high guide arm for the packaging material, said high guide arm being arranged above the held compressed bale. 
     
     
         8 . The packaging device as claimed in  claim 1 , wherein the web guide has a guide arm with a connection for fastening to a press column ( 17 ). 
     
     
         9 . The packaging device as claimed in  claim 1 , wherein the supply device has a controllable conveying means for conveying the packaging material. 
     
     
         10 . The packaging device as claimed in  claim 1 , wherein the wrapping apparatus has a variable web store for the packaging material. 
     
     
         11 . The packaging device as claimed in  claim 1 , wherein the web store is configured as a controllable dancer having tensioning rollers, for the packaging material, that are adjustable relative to one another. 
     
     
         12 . The packaging device as claimed in  claim 1 , wherein the wrapping apparatus has a web deflector for the packaging material. 
     
     
         13 . The packaging device as claimed in  claim 1 , wherein the wrapping apparatus has a controllable conveying means for conveying the packaging material. 
     
     
         14 . The packaging device as claimed in  claim 1 , wherein the wrapping apparatus has a cutting and welding apparatus for the packaging material. 
     
     
         15 . The packaging device as claimed in  claim 1 , further comprising another supply device wherein the packaging device ( 2 ) has two supply devices and the wrapping apparatus has two feed devices that are arranged on either side of the compressed bale on in each case one transport means and are each connected to a supply device. 
     
     
         16 . The packaging device as claimed in  claim 15 , wherein the feed devices are provided and configured to tauten an upright web film curtain, between one another and to lay the latter laterally around the compressed bale. 
     
     
         17 . The packaging device as claimed in  claim 15 , wherein the feed devices each have a web deflector, a web store, conveying means and a cutting and welding apparatus. 
     
     
         18 . A baling press for highly compressed bales comprising a packaging device, the packaging device comprising:
 a supply device for supplying a film web packaging material;   a wrapping apparatus for applying an annular surrounding film sleeve, to free lateral faces of the compressed bale held between press rams;   a transport means for moving the wrapping apparatus; and   a web guide for feeding the packaging material, wherein:   the wrapping apparatus is arranged so as to be movable by way of the transport means relative to the compressed bale;   the supply device is arranged separated spatially and kinematically from the wrapping apparatus;   the supply device is arranged stationarily;   the supply device comprises a web supply receptacle for a coil web supply, and the web guide feeds the packaging material to the wrapping apparatus; and   the receptacle and the web supply are arranged at a gap distance from the held compressed bale, wherein the web guide bridges the gap distance.   
     
     
         19 . A method for packaging highly compressed bales on a baling press by means of a packaging device, the method comprising the steps of
 moving a wrapping apparatus relative to the compressed bale by way of a transport means;   applying, with a wrapping apparatus, an annular sleeve, made of a film web packaging material, to the free lateral faces of the compressed bale held between press rams; and   feeding the web-like packaging material is fed to the wrapping apparatus from a supply device which is arranged in a manner separated spatially and kinematically from the wrapping apparatus.   
     
     
         20 . The packaging device as claimed in  claim 1 , wherein:
 the supply device is a single and one-sided arrangement cooperating with the wrapping apparatus as a single wrapping apparatus; and   the film web of packaging material is fed on only one bale side from the stationary supply device of the wrapping apparatus.
