Definitions

  • the folding is carried out without the need to beat the packaging sheet manually.
  • a packaged flat sided body having two main faces, two end faces and two side faces, in which a single sheet of pliable material is folded around both main faces and both end faces of the body, characterized in that a band is tensioned around the side and end faces of .the package and folds of said material are laid on the side faces outside the band.
  • apparatus for packaging a flat sided body having two main faces, two end faces, and two side faces, after a single sheet of pliable material has been folded around both main faces and both end faces of the body said apparatus including a conveyor for the body, a generally horizontal band guide disposed above the conveyor for passing a band horizontally around the side and end faces of the body to form partial folds in material protruding from opposite side faces and generally in the plane of the end faces, location blocks at least one of which is movable towards the other to enable the blocks to contact sheet material on opposite end faces when a band is being passed around the side and end faces, said band guide and location blocks being vertically movable out of the path of a body on the conveyor, and means for passing bands around the main and side faces to form completed folds against the side faces.
  • the pliable material is preferably sheet metal, e.g., sheet steel. It is found that even with a stiff material like sheet steel the tensioning of the first band manually or automatically around the side and end faces itself forms the partial folds in the protruding material that are required at the corners of the package without having to beat it manually. It is found that it is easier to form the partial folds if location blocks contact the sheet material on opposite end faces before tensioning the first band, and if the location blocks project beyond the side faces to support protruding material during tensioning of the first band.
  • top and bottom faces can be regarded as the main faces and, of the other faces, either the shorter or the longer pair of opposed faces can be regarded as being the end faces, although it is normal to regard the shorter pair as being the end faces.
  • the completed folds against the side faces can be folded down in any convenient way but preferably further bands are tensioned around the main and side faces at least to assist in forming completed folds against the side faces.
  • the tensioning of the further bands can be the only step that completes the folds against the side faces but blocks can be advanced against the protruding material to assist in completing the folds.
  • the body can be packaged with two sheets by laying one sheet on only one main face of the body before folding it on to the side and end faces in accordance with the invention.
  • the second sheet can then be laid on the other main face before folding it on to the side and end faces, again in accordance with the invention.
  • a single sheet of pliable material is folded around both main faces and both end faces before the step of tensioning the first band around the side and end faces.
  • means such as blocks, are preferably provided to be brought into contact with the material protruding from the side faces initially lying in the plane of said first mentioned main face during the formation of the folds against the side faces.
  • FIG. 1 shows a perspective view of apparatus for carrying out the method of the invention
  • FIGS. 2 to 5 show different stages in one embodiment of the packaging method of the invention.
  • FIG. 1 shows a conveyor 2 along which piles 4 of sheet steel are delivered to be packaged.
  • a single steel sheet 6 has been folded around both main faces 8 and 10 and both end faces 12 and 14 of the body formed by the pile 4 either by hand or by a separate machine which does not form a part of the present invention.
  • the sheet 6 is folded with an overlapping join 16 on the top surface 8.
  • Flaps of material 22 protrude from opposite side faces 18 and 20 of the body 4 generally in the plane of the end faces 12, 14, and flaps of material 24 protrude from opposite side faces 18, 20 generally in the plane of the main face 8, 10, by an amount which is conveniently equal to or between and percent of the pile height thereby ensuring that on folding the top and bottom flaps 24 at each side the flaps 24 will overlap without fouling each other.
  • the conveyor 2 includes a portion 30 with longitudinally extending movable bands 31 which can be driven to position the pile 4 where desired on the portion 30.
  • a rectangular guide 32 for a known type of automatic banding arrangement is positioned above the driven portion 30 of the conveyor and is normally positioned out of the path of a pile 4 moving along the conveyor but can be moved down to surround the pile 4.
  • the guide 32 has a groove around its inside.
  • Support and location blocks or plates 34 extend between the longer sides of the guide 32 and at least one of the blocks 34 is movable towards the other along the guide 32 to adapt the guide 34 for different sizes of pile 4.
  • the blocks 34 are longer than the ends l2, 14 of the pile 4.
  • There are slots 35 extending upwardly from the bottom edge of the blocks 34 which enable the blocks to be lowered with their bottom edges below the bands 31. This permits the guide 32 and groove 36 to be positioned mid-way up the height of even a low pile of sheets.
  • the preferred method of the invention is as follows:
  • the pile 4 having the sheet 6 folded around it as shown in FIG. 1 is advanced to the portion 30 of the conveyor and the guide 32 is lowered to surround the pile 4.
  • the pile 4 and at least one of the support and location blocks 34 are then moved so that the blocks 34 contact the sheet material on opposite end faces l2, 14 including the protruding flaps 22 as shown in FIG. 2.
  • a band 42 for example of steel or nylon, is then passed automatically in a known manner around the side faces 18, 20 and end faces 12, 14 of the pile 4 utilizing the grooves 36 in the blocks for guiding the band 42 along the end faces 12, 14 and the groove in the guide 32 for guiding the band at the sides.
  • the guide 32 and grooves 36 are preferably positioned mid-way up the height of the pile.
  • the band 42 is then tensioned automatically to produce partial folds 44 in the flaps of material 22 protruding from opposite side faces 18, 20 as shown in FIG. 3.
  • the blocks 34 prevent the flaps 22 from folding out of the plane of the ends 12, 14 of the pile away from the sides 18, 20.
  • the blocks 34 are now released from the end faces 12, 14 and the guide 32 (not shown in FIGS. 2 and 3) is raised allowing the pile 4 to be advanced along the conveyor 2.
  • the pile 4 is advanced until it projects partly through the guide 38 to the position shown in FIG. 4 (part of the guide 38 is not shown in FIG. 4 for clarity).
  • a band 46 is now passed loosely around the main faces 8, l and side faces 18, 20 adjacent to the front end of the pile 4 and overlapping the folds 44 as shown in FIG. 4.
  • the blocks 40 are now advanced towards the side faces 18, 20 and the inclined faces 41 are brought into contact with the bottom flaps of material 24 to ensure that in the completed package the bottom flaps 24 are folded under the top flaps 24 as shown in FIG. 5.
  • the band 46 is now tensioned.
  • the pile is then advances so that its rear end 14 is near the guide 38 so that another band 48 can be passed loosely around the end of the pile in the same way as the band 46.
  • the blocks 40 are again ad vanced for the same reason as before.
  • the band 48 is now tensioned to form completed folds on the side faces 18, 20 as shown in FIG. 5, thus completing the packaging operation.
  • the completed package in accordance with the invention is a flat sided body having two end faces 12, 14 and two side faces 18, 20.
  • the band 42 is tensioned around the side and end faces and folds 24 of the packaging material are laid on the side faces 18, 20, outside the band 42 in contrast to a normally packaged pile.
  • the method described above provides considerable saving in time and manpower in comparison with the methods of packaging piles of steel with steel sheet presently used.
  • a method of packaging a flat sided body having two main faces, two end faces and two side faces in which a sheet of pliable material is laid on at least one main face of the body, and folded on to the end faces with a portion of said sheet protruding beyond opposite side faces, comprising contacting the sheet material on opposite end faces with location blocks, then tensioning a first band around the side and end faces thereby forming partial folds in the material protruding from opposite side faces and generally in the plane of the end faces, the location blocks projecting beyond the side faces and supporting the protruding material during the tensioning of the first band and folding the material protruding from opposite side faces and generally in the plane of said one main face to form completed folds of the protruding portions against the side faces.
  • a method as claimed in claim 1 in which a single sheet of pliable material is folded around both main faces and both end faces before the step of tensioning the first band around the side and end faces.
  • a method as claimed in claim 3 in which the sheet of pliable material is laid on the other main face and including the step of contacting the material protruding from the side faces and initially lying in the plane of said one main face during the formation of the completed folds against the side faces and folding it against the side faces, and subsequently contacting the protruding material initially lying in the plane of the other main face and folding it against the side faces thereby ensuring that the protruding material initially lying in the plane of said one main face is folded against the side faces underneath the protruding material initially lying in the plane of the other main face.
  • Apparatus for packing a fiat sided body having two main faces, two end faces, and two side faces, after a single sheet of pliable material has been folded around both main faces and both end faces of the body with a portion of said sheet protruding outwardly beyond opposite side faces said apparatus comprising a conveyor for the body, a generally horizontal band guide disposed above the conveyor for passing a band horizontally around the side and end faces of the body to form partial folds in material protruding from opposite side faces and generally in the plane of the end faces, location blocks at least one of which is movable towards the other to enable the blocks to contact sheet material on opposite end faces when a band is being passed around the side and end faces, said band guide and location blocks being vertically movable out of the path of a body on the conveyor, and a generally vertical band guide for passing bands around the main and side faces to form completed folds against the side faces.
  • Apparatus as claimed in claim 6 including blocks advanceable towards the side faces to contact the 5 material protruding from the sidefaces and initially lying in the plane of one main face.
