Description

  The present invention relates to a method for palletizing a winding roll wound around a winding core.

  Winding rolls of strips of paper, film, metal, etc. are handled in a horizontal position because they are handled in the horizontal position at the time of processing, but in the state of standing on a pallet for reasons of transportation efficiency at the time of shipment. Often transported. In addition, these winding rolls are generally wound on a core after processing a belt-like sheet of paper, film, metal, etc. For example, a belt-like sheet having a width of about 1.5 m is wound into a core with a length of about 3000 m. Since it winds up, it becomes a very heavy roll.

  For such a method of standing and palletizing the take-up roll body, a method of directly clamping the take-up roll body body with a roll clamp type forklift is common, but in the case of a product with low surface strength Gripping marks and deformation occur on the product surface. For this reason, there are methods such as weakening the clamping force of the clamp, or clamping with a cushioning material between the take-up roll body and the fork, but complete measures are taken simply by reducing the pressure on the wind-up roll body. In addition, there is a high possibility that the take-up roll body will be dropped when it is lifted, and the work must be done carefully, which causes a reduction in work efficiency.

  As a means different from the above, a palletizing method for holding the tubular core itself by inserting a robot hand into the tubular core of the winding roll body is disclosed in Japanese Patent Laid-Open No. 2001-163594 (Patent Document 1). However, when handling products with different inner diameters of the tubular core, it is necessary to use multiple robot hands, and when lifting a roll body with a weak winding tension, the outer part of the winding is caused by the weight of the winding roll body during reversal. There arises a problem that the phenomenon of tapering off occurs or the tubular core comes off and the product falls.

In addition, as a special example, a method of introducing an original palletizing facility is disclosed in Japanese Patent Laid-Open No. 7-25466 (Patent Document 2). However, the situation is that it is not easy to introduce because it leads to the generation of capital investment costs and the limitation of the work place.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a palletizing method that does not cause damage or grip marks on a product surface and does not cause winding deviation in a palletizing method for a winding roll wound around a tubular core.

The above-described problems of the present invention have been solved by the following means.
(1) Attach a pallet with protrusions at the center on both sides of a horizontal take-up roll body without protruding tubular cores so that the protrusions are inserted into the tubular core of the take-up roll body. A method for palletizing a take-up roll body, wherein the take-up roll body is held up by a forklift via a pallet.
(2) A pallet with an insertion hole in the center is attached to both sides of the horizontal winding roll body from which the cylindrical core protrudes so that the cylindrical core of the winding roll body is inserted into the insertion hole. A method for palletizing a take-up roll body, wherein the take-up roll body is held up by a forklift via a pallet.

  ADVANTAGE OF THE INVENTION According to this invention, in the palletizing method of the roll body wound up by the winding core, the palletizing method which does not generate | occur | produce a damage and a grip trace on a product surface, and does not generate | occur | produce winding deviation can be provided.

  Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited to these embodiments without departing from the gist of the present invention. The palletizing method of the take-up roll body of the present invention does not pinch the body of the product when palletizing the take-up roll body, so that damage and grip marks do not occur and both end faces of the take-up roll body Since the side is narrowed by a forklift via a pallet, it is a palletizing method that produces an excellent effect that palletizing can be performed without causing slipping off or core disengagement even with a loose winding roll body.

  FIG. 1 is a schematic perspective view of a winding roll body in which the tubular core does not protrude from the side surface portion. The winding roll body 1 is formed by winding a belt-like sheet of paper, film, metal or the like around a tubular core 11 in a roll shape. The tubular core 11 does not protrude from the side surface of the take-up roll body 1. Moreover, it is preferable that the shape of the outer peripheral surface of the tubular core 11 is circular, but the shape of the inner peripheral surface of the tubular core is not particularly limited as long as a pallet protrusion 3 described later can be inserted.

  FIG. 2 is a perspective view of a pallet having a protrusion at the center. The pallet 2 is a conventionally well-known pallet formed from a top plate 21, a girder member 22, and a lower plate 23, for example, a pallet described in Japanese Patent Application Laid-Open No. 11-198934. A fork insertion port 24 into which a fork of a forklift is inserted is formed on at least one pair of opposing sides. The lower plate 23 is not particularly required if the pallet storage place is flat.

  The protrusion 3 is fixed to a central portion where diagonal lines connecting opposing corners of the top plate 21 of the pallet 2 are orthogonal to each other. The protrusion 3 is formed in a cylindrical shape from, for example, wood or synthetic resin, and is fixed to the top plate 21 with a bolt 31 penetrating the protrusion 3 in the vertical direction. The protrusion 3 plays a role of positioning the winding roll body 1 shown in FIG. Therefore, a height of at least 10 mm is necessary, and a height of 40 mm to 80 mm is preferable. The shape of the protrusion 3 is not necessarily limited to the columnar shape shown in FIG. 2 and may be, for example, a prismatic shape. For example, in the case of the columnar shape, the diameter is 10 mm to 20 mm smaller than the inner diameter of the tubular core 11. Is preferred. The fixing method need not be limited to fixing with bolts. For example, there is no problem as long as sufficient fixing strength can be obtained even with fixing with a nail or the like.

  Next, a palletizing method using the pallet shown in FIG. 2 will be described with reference to FIGS.

  FIG. 3 is a schematic side view illustrating a first stage state for explaining a palletizing method of a winding roll body in which the tubular core does not protrude from the side surface portion. First, the winding roll body 1 is placed horizontally on the temporary table A. The shape of the surface of the temporary table A that contacts the winding roll body 1 needs to be a shape that does not roll down even when the winding roll body 1 is placed, such as an M shape. The method for transferring the winding roll body 1 onto the temporary table A is not particularly limited, and is a general method such as fishing with a hoist crane.

  Next, the pallet 2 is attached to both side portions of the winding roll body 1. At that time, the protrusion 3 is inserted into the tubular core 11 of the winding roll 1. Moreover, it is necessary to make the width | variety of the temporary placement stand A narrower than the width | variety of the horizontal direction of the winding roll body 1 so that the temporary placement stand A and the pallet 2 may not interfere. Moreover, when the pallet 2 is attached to the both side surfaces of the take-up roll body 1, it is necessary to set the height of the temporary placing table A so that the pallet 2 and the floor surface do not interfere with each other.

  Next, FIG. 4 is a perspective view showing a state of a second stage following FIG. 3 for explaining the palletizing method. A fork F of an inverter clamp type forklift is inserted into the fork insertion port 24 of both pallets and lifted and rotated while applying clamping pressure to stand upright so that the side surfaces are in the vertical direction. Even if the clamping pressure at this time is increased to, for example, the maximum pressure of the forklift, the pressure is distributed over the entire side surface of the take-up roll body 1, so that the product is not affected.

  Finally, FIG. 5 is a perspective view of the winding roll body palletized by the palletizing method of the present invention. It is preferable that the standing winding roll body 1 and the pallet 2 are bound by a binding band 4. The binding band 4 is bundled through the fork insertion openings 24 of the pallet 2 on both sides of the winding roll 1, but if it can be securely bundled, for example, the center of the pallet 2 is passed without passing through the fork insertion opening 24. For example, they may be bundled at other positions. The binding means may be, for example, a method of binding the top pallet with a polypropylene binding band or a polyethylene terephthalate binding band, or a method of binding the whole with a stretch packaging film.

  In the above embodiment, the tubular core does not protrude from the side surface portion of the take-up roll body. However, the tubular core may protrude from the side surface portion of the take-up roll body. In this case, the winding core does not necessarily have a tubular shape and may be a cylindrical shape, but in this embodiment, the winding core is described as a tubular shape. Hereinafter, the palletizing method for the winding roll body in which the tubular core protrudes from the side surface will be described in detail.

  FIG. 6 is a schematic perspective view of a winding roll body in which a tubular core protrudes from a side surface portion. The winding roll body 5 is formed by winding a belt-like sheet of paper, film, metal or the like around a tubular core 51 in a roll shape. Tubular cores 51 protrude from both side surfaces of the winding roll body 5. The tubular core 51 is a conventionally well-known tubular core as described in, for example, Japanese Utility Model Laid-Open No. 7-12230. However, the tubular core 51 is supported even if the weight of the winding roll body 5 is applied to a portion protruding from the winding roll body 5. It is necessary to have the strength to be obtained. For this reason, the length from which the tubular core 51 protrudes from the side surface portion of the take-up roll body 5 is required to be at least 10 mm or more, and preferably 40 mm to 80 mm.

  FIG. 7 is a perspective view of a pallet having an insertion hole at the center. The pallet 6 is a conventionally well-known pallet formed from a top plate 61, a girder member 62, and a lower plate 63, like the pallet 2 described above.

  A tubular core insertion hole 65 is formed in a central portion where diagonal lines connecting opposite corners of the top plate 61 of the pallet 6 are orthogonal to each other. The tubular core insertion hole 65 plays a role of positioning the winding roll body 5 shown in FIG. 6 with respect to the pallet and preventing it from dropping when it is lifted.

  FIG. 8 is a schematic side view showing a state of a first stage for explaining a palletizing method of a winding roll body in which a tubular core protrudes from a side surface portion. The pallet 6 is attached to both side portions of the take-up roll body 5 placed horizontally on the temporary placement table A. At that time, the tubular core 51 of the winding roll body 5 is inserted into the tubular core insertion hole 65 of the pallet 6. The diameter of the tubular core insertion hole 65 needs to be larger than the outer diameter of the tubular core 51, and preferably φ10-20 mm larger than the outer diameter of the tubular core 51. The length of the tubular core 51 is set such that the tubular core 51 does not protrude from the bottom surface of the pallet 6 when the pallet 6 is attached to the winding roll body 5.

  Subsequent palletizing methods are palletized in the same manner as the second and third stages shown in FIGS.
