Definitions

  • the object of the invention is to provide a remedy for said inconveniences, and relates to a method for removing the wrapping from the bottles in a simple way.
  • the invention may be applied not only to bottles but also to cans, tins, and other containers, provided that they have a thickened circumferential portion on which they can be suspended by the supporting member which will be described below.
  • the removal of the wrapping from the bottles take place by placing the wrapping to give the bottles an upright position, providing a longitudinal cut in two opposite walls of the wrapping, said cuts preferably extending along the whole length of the walls and being situated at the same height from the bottom of the wrapping, preferably on a level below a thickened circumferential portion of the neck of the bottles or of the side wall of the cans, cutting a third cut in the third wall of the wrapping at the same height as said first cuts, bending up the top portion of the wrapping above said cuts so as to expose the thickened circumferential portions, bringing the bottles and the wrapping, thus opened, to engage a supporting member for the bottles so as to suspend the bottles in said supporting member by said thickened circumferential portions, and removing the wrapping from the bottles.
  • the invention also relates to an apparatus for bringing the invention into practical use.
  • This apparatus consists of two conveyors, situated perpendicularly to each other.
  • a parcel of bottles is fed along one conveyor to the second conveyor and along said second conveyor.
  • the parcel passes two knives situated on each side of the conveyor to produce two longitudinal cuts along the walls of the wrapping which are parallel with the direction of movement of the parcel.
  • a cutting member cuts one side of the wrapping which is parallel with the direction of movement of this conveyor.
  • the wrapping is removed, either by a member that pushes the bottom of the wrapping downward or by a suction member that engages the bottom of the wrapping from the outside.
  • the wrapping can be blown away by pressurized air.
  • each vertical cutting member producing a cut extending from the bottom of the wrapping up to cuts extending parallel with the bottom.
  • Such a cut facilitates the insertion of the member which has to push away the wrapping from the bottles, and enables the wrapping to be easily removed from the bottles.
  • FIG. 1 shows, diagrammatically, a complete apparatus.
  • FIG. 2 illustrates how said apparatus works.
  • FIG. 3 shows an embodiment of a cutting member of the apparatus.
  • FIGS. 4 and 5 illustrate the operation of the supporting member and the means for removing the wrapping.
  • FIGS. 6, 7 and 8 illustrate various steps of cutting up a wrapping.
  • the apparatus of FIG. 1 comprises a first conveyor 1 upon which a parcel 2 of bottles is being fed in the direction of arrow 3, a second conveyor 9 which is perpendicular to conveyor 1 and upon which the parcel will be fed as indicated by arrow 10, and a third conveyor 11 which is perpendicular to conveyor 9 and upon which the parcel will be fed as indicated by arrow 12.
  • the conveyors can consist of endless belts. Preferably, the belts shall be synchronized so as to produce a continuous feeding. Alternatively, the conveyors can consist of stationary, smooth surfaces upon which the parcels are slidable by means of pushing members, not shown. The side walls of the parcel are situated in the same direction during the entire operation, i.e. the parcel does not rotate when being fed from one conveyor to the next one.
  • FIG. 3 shows the right-hand knife 17.
  • the knife consists of a metal plate which has two sides 18 and 19 which make a right angle.
  • the hypotenuse of said triangle has a sharp edge 21. Said edge does not extend along the entire length of the hypotenuse, but there is a portion 23 which extends from the point 22 and which has no sharp edge.
  • the cutting member 17 is so mounted in the support 13 that its plane surface is parallel with the bottom of conveyor 9 and its side 18 is parallel with the direction of movement of conveyor 9.
  • the knives 16 and 17 are mounted on such a height relative to parcel 2 that the thickened circumferential portion 25 of the bottles 24 is situated higher than knife 17.
  • the distance between the parallel edges 18 of the two knives 16 and 17 is somewhat smaller than the width of parcel 2.
  • a knife 26 which is similar to knife 16 and which is mounted on one of the elongated support members 27.
  • conveyor 11 there are a plurality of elongated, parallel members 27, which are clearly illustrated in FIGS. 4 and 5.
  • the members 27 are spaced from each other a distance which corresponds to the width of the neck of bottles 24, and which is smaller than the outer diameter of the thickened circumferential portion 25 of the bottles. Consequently, a bottle which is inserted from the left between two elongated members of FIG. 1 will be hanging suspended on said elongated members.
  • One of the elongated members, see reference character 28, supports a rod or strip 29 which is shaped so as to bend up a portion aaeaaes of the wrapping, which will be described below.
  • a vertical knife 31 is fastened to one of the elongated members 27, see reference character 30.
  • This knife too, is shaped as a triangle and has a sharp edge 32. A sharp edge is also provided on the portion of the side 33 which is adjacent the point 34. Below the elongated members 27 there is an area 35 which has no conveyon A rectangular plate 36 is movable vertically above said area, to act as a pushing member. The plate is movable in an opening 37 in the elongated member 30, which is one of the elongated members 27.
  • the rectangular plate 36 may have teeth on its lower edge.
  • FIG. 1 shows only one parcel 2 of bottles.
  • the parcel 2 contains bottles 24 arranged in rows, as clearly disclosed in FIG. 5.
  • a cut 47 in wall 38 which is opposite to wall 39, said out extending from the bottom 46 of parcel 2 up to cut 40. Cuts 45 and 47 are required for enabling plate 36 to be inserted into parcel 2, as illustrated in FIG. 5, and for enabling the wrapping to be released from the bottles.
  • the wrapping can be removed from the bottles by a vertical movement of plate 36 in the direction of arrow 48.
  • the bot tom edge of the plate has teeth to prevent parcel 2 from sliding away from plate 36 during the downward movement of the plate in the opening 35 of the conveyor.
  • the plate moves a distance required for entirely removing Wrapping 2 from the bottles.
  • pressurized air can be used, acting in the direction of arrow 48, or a suction device can be provided in opening 35 to remove wrapping 2 from bottles 24.
  • knife 31 can be omitted if plate 36 is lifted so high as to allow an opened wrapping to pass below the lower edge of the plate.
  • the illustrated apparatus can be provided with two auxiliary members 49 and 50 which are fastened to the upper portion of holder 13.
  • the auxiliary members are elongated and parallel with the feeding direction of conveyor 9. They are fastened to holder 13 in such a position that each auxiliary member is situated between two rows of bottles. Consequently, the two auxiliary members will press down the top portion of the wrapping between two rows of bottles. Therefore, the sides of the wrapping which are parallel with the feeding direction will be taut, thus facilitating the operation of the knives 16 and 17.
  • auxiliary members 50 can be replaced by rollers arranged to roll upon and press down the top of the wrapping.
  • the parts of the apparatus can be varied very much within the scope of the invention.
  • the essence of the invention resides in first cutting two cuts 40 and 41 in wrapping 2 and subsequently a third cut 42, lifting up the top portion 44 and suspending the bottles in the elongated members 27. This having been done, wrapping 2 can be removed from the bottles in any suitable way.
  • a third cut can, within the scope of the invention, be provided in the top portion 44 so as to extend between the two cuts 40 and 41. When the top is bent up there will be formed two lid portions instead of one as described above.
  • the parcel can contain two or more layers of bottles or cans, one layer situated upon another layer. This necessitates a number of supporting members which is equal to the number of layers. These supporting members must be situated above each other.
  • bottles When the bottles have been freed from the wrapping as described above, they can be transferred by known methods to a conveyor to be further treated, for instance washed, filled and the like.
  • Apparatus for removing the wrappings from parcels of bottles comprising a first conveyor and a second conveyor positioned perpendicular to each other and having means for moving parcels along the first conveyor to the second conveyor and along the latter, two cutting members supported at the same level above said first conveyor to produce horizontal cuts in two opposite sides of the wrapping of each parcel when it passes said cutting members, a third cutting member supported above said second conveyor at the same level as said two cutting members to produce a horizontal cut in a third side of said wrapping when it passes said third cutting member, a bendingup member supported adjacent to said second conveyor to bend up the top of said wrapping released by said cuts, supporting means positioned above said second conveyor adapted to suspend the bottles of said parcels by their necks when the bottles are moved forward relative to said supporting means, and means positioned adjacent to said second conveyor for removing the wrappings from the bottles while the bottles are hanging from said supporting means, said means for removing the wrappings consisting essentially of at least one plane vertically disposed plate and means for moving said plate vertically to engage the bottoms of said wrapping
