Description

The present invention relates to a product roll packaging method, and in particular, a single product package in which a roll-shaped product roll obtained by winding a sheet-like material such as paper, cloth or film on a hollow cylindrical core is sized to a predetermined size. The present invention relates to a packaging method for packaging with materials.

  Conventionally, when packaging a roll-shaped product roll obtained by winding a sheet-like material such as paper, cloth, or film on a hollow cylindrical core, a packaging material that has been cut to a width slightly wider than the roll width of the roll is used. Wrap it around the body of the product roll and fasten it with heat seal or adhesive tape, and then converge or fold the excess part protruding from both end faces of the product roll and fasten it with tape, tack label or heat seal etc. It was fastened at three places on the part and both end faces.

  However, when a flexible film such as polyethylene is used as the packaging material, it is difficult to apply the above wrapping method because the end surplus portion hangs down from the end surface of the roll. For fixing the surplus part, a cylindrical slidable piston rod inserted into the core hole in the core is provided separately, and the flexible packaging material hanging from the end face of the wound roll is sucked by the suction mechanism and rotated while converging. Means have been proposed for twisting the packaging material by rotating the suction body by a driving mechanism and for pushing the twisted packaging material into the core hole of the roll core by the piston rod. (For example, see Patent Document 1)

  However, in the above packaging, the end of the excess part is fastened at the corners, and in the case of the product roll body packaging, the wrapping material is wrapped around the product roll body part with adhesive tape or heat sealing. Therefore, due to poor tape tension and imperfect sealing of the heat seal, the moisture and dustproof effects in the packaging material are not sufficient, and a complete insecticidal effect is required especially for protecting the product roll used for food and hygiene products. There was a problem.

The present invention addresses the above-mentioned circumstances, seen wrapped write no particular product roll bonded body portion in one of the packaging material, more in finding that the yield斂narrowing, of reducing the sealing portion packaging material The purpose is to ensure the protection of product rolls used for foods and sanitary goods by eliminating incomplete tape application, heat sheets, etc. with a single sealing part.

In other words, the feature of the method of the present invention that meets the above-described purpose is that when a roll-shaped product roll obtained by winding a sheet-like material on a hollow cylindrical core is packaged with a single sized packaging material, the size is cut. Further, a lowering lifter is provided at the central portion of the upper plate for unfolding the packaging material so that the product roll wound up on the hollow cylindrical core can be lowered, and the single packaging material is unfolded on the upper plate. part of the product roll round surface the product roll is lowered while converging the barrel portion packaging material by and put it down lifter up and down, after the required downward, converging the packaging material surplus portion of the upper dish-shaped vacuum panel In the roll packaging method, the collected packaging materials are squeezed and pushed into the hollow cylindrical core of the product roll, and then fastened with a tape or the like.

  Claim 2 is a method for converging the body wrapping material when the product roll is lowered, and a converging plate is provided on the periphery of the central portion where the product roll of the upper plate descends, and the converging plate is lowered. It is characterized by being converged by circumscribing the body wrapping material of the product roll.

According to the packaging method of the present invention, the dimensioned packaging material is developed on the upper plate, and the product roll wound up on the hollow cylindrical core is placed on the upper and lower end surfaces and lowered. The lower end face and body wrapping material are packaged without the need for fastening such as tape and heat sealing, and the fastening is only at one place on the upper end face of the lowered product roll, and the fastening work is extremely troublesome. Not only is it simple, but there is no relationship between poor tape application, poor seal, etc., and even in the packaging of product rolls used for foods and sanitary products, it has the effect that it can be reliably packaged with complete protection.

Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 (a) to 1 (f) show the packaging method according to the present invention step by step. In these figures, reference numeral 1 denotes a single wrapping material that has been cut to a required size. First, the material 1 is developed on the prepared upper plate 2, and a hollow product roll R obtained by winding a sheet-like material on a hollow cylindrical core is placed on the center portion with the circular surface up and down.

  The upper plate 2 is provided with a hole 3 having a diameter larger than the diameter of the product roll in the center part on which the product is placed so that the product roll R can pass through the hole 3. A lowering lifter 4 that lowers the product roll is disposed, and the product roll R can be lowered with the lowering of the lowering lifter 4. Hereinafter, description will be made sequentially with reference to the drawings.

Figure 1 (b) is the hollow cylindrical winding core in wound-up hollow product roll R is placed on the packaging material 1 which is one size cut being deployed on the upper plate 2, falling lifter 4 is the It is in the state located under the product roll R. At this time, with respect to the product roll R descending to the peripheral edge of the central portion of the upper plate 2, a converging plate 5 made up of a pressing bar for converging the body wrapping material in a circumscribing state is provided on the outer periphery of the body. However, it is not yet ready for operation.

As shown in FIG. 3, the converging plate 5 provided at the peripheral edge of the center of the upper plate has a peripheral edge of the hole 3 where the product roll R in the central part of the upper plate 2 descends, and the peripheral edge of the central hole 3 serves as a rotating part 5 '. It is provided so as to be able to rotate, and comes into contact with the outer periphery of the roll R as the hollow product roll R descends to converge the body packaging material of the product roll R. In addition, it is also preferable to attach a plate or a rotating roller to the tip of the converging plate 5 to smooth the converging action.

In FIG. 1A, since the product roll R wound up on the hollow cylindrical core is in a state before being lowered, the product roll R is merely held on the lowering lifter 4 via the packaging material 1. There is no convergence effect on the body wrapping material.

  FIG. 1 (b) is the stage where the product roll R descends with the lowering of the lowering lifter 4 from the state of (a) above, and the convergence with respect to the body wrapping material begins, and (c) further lowers the product roll R. This is the stage where the packaging material surplus part 1a is left in the upper part. Thus, so far, the lower end surface and the body portion of the product roll R have been packaged by the packaging material, and only the upper end surface side is in an unwrapped state.

FIG. 1 (d) shows a state in which the upper surplus portion 1a is converged using a vacuum disk 6 in order to seal the remaining packaging surplus portion 1a and complete the packaging, and remains on the upper portion of the trunk packaging. The surplus packaging material 1a is sucked by the dish-like vacuum disk 6 and collected in the center as shown in FIG. 5 (e), and the converged surplus is placed inside the hole in the center of the hollow cylindrical core of the product roll R. The packaging of the product roll R is completed by fixing the tape or tack label 7 to the protruding portion as shown in FIG.

  2 (a) to (e) show the state of each packaging stage corresponding to FIGS. 1 (a) to (e) above, and the product roll R is placed on the center of the sized packaging material 1, and then The product roll R descends, and the body wrapping material starts to converge (b), and further descends to converge the body wrapping material, so that the surplus part 1a is formed at the upper part (c).

(D) The figure shows a state where the surplus part formed in the upper center part of the product roll is further converged and sucked by the dish-like vacuum disk 6 from the upper part. (E) The figure is sucked and the upper packaging material surplus part is surplus portions as illustrated in finally FIG. 1 (f) in a state in which rammed into the middle air cylinder core wound within the winding core of the product roll R is plunged, is fastened with a tape or tack labels, etc. Thus, the packaging method according to the present invention is completed.

This is done by wrapping a hollow cylindrical product roll in a single piece of packaging material that has been cut as described above without wrapping it so that it can be wrapped in a furoshiki, and fastening only one part of the upper end surface with tape or the like. Invention wrapping is performed, and it is possible to simplify the troubles of conventional incomplete tape application, heat sheet and the like.

(A)-(f) is explanatory drawing which showed this invention packaging method in order. (A) to (e) is a schematic diagram showing a packaging mode in the order in step (a) to (f) in FIG. (A), (b) is a converging plate mounting mode at the center of the plate, (a) is a front schematic view, and (b) is a plan schematic view.
