TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention is used when loading and transporting a roll of a sheet, a film, a thread, or the like in a roll, a coil, a bobbin, or a cheese shape, and is particularly suitably used as a transport material of a roll product such as a film. It relates to materials for transporting scrolls.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a packing method for transporting a scroll horizontally, a method of grounding and fixing the scroll to a rug or a pad on a pallet (for example, see Patent Literature 1) and a method of hanging the scroll without contacting the surface of the scroll are known. Although there is a mold method (for example, see Patent Document 2), the present invention belongs to the latter, and has a circular or U-shaped shape provided at the center of a pair of rectangular plates (receiving members) larger than the diameter of the scroll. A method in which the axis of the scroll (paper tube, etc.) is directly or indirectly fitted with a washer in the hole and suspended and supported. Is widely practiced. Roll products such as films are various in size from small (load: 10 to 100 kg), medium (100 to 350 kg), and large (350 to 1200 kg). Therefore, the size of the receiving material is approximately 200 mm to 1200 mm square. . There are various ways of loading on these pallets, such as storing them in storage cases (cardboard cases, wooden boxes, etc.) and loading them on the pallet in one or more stages, and lighter ones in the small size are placed in the receiving material itself. There is a case where a fitting portion is provided to fit the upper and lower receiving members and stacked on the pallet in several stages. In the case of medium to large and heavy rolls, place the receiving material on a pallet, protrude the ends of the rolls, and lower the rolls that have been lifted by using the center of the rolls. However, it requires a large number of workers and is a large-scale operation. Since the stacking is heavy, the rolls are stacked in units of one roll on one pallet.
Currently used receiving materials include wood cut products, plastic injection molded products, corrugated products, and iron plates, but have various problems.

[0004]
[Problems to be solved by the invention]
The method of fixing a receiving material and a roll with a binding band such as a PP band, which is currently widely used, tends to overtighten the binding band in order to prevent loosening during transportation of the binding band. It may bend to the roll side, and the end face of a roll product such as a film may be damaged while the receiving material is damaged. In addition, the work of fixing the PP band by making one round is also complicated.
[0005]
Further, the PP band and the like used for bundling are trash after the roll is taken out, leaving a burden on the consumer for disposal. Furthermore, cardboard cases and wooden boxes are not reused at present, and become waste after use.
[0006]
Use of a corrugated cardboard case or wooden box is preferable because it rubs when storing, storing, transporting, and opening the rolls, causing paper dust and wood dust to adhere to roll products due to static electricity and causing film contamination. Absent.
[0007]
Since a heavy roll cannot be lifted by human power, it is generally hung with a sling applied to the shaft core protruding from both ends of the roll, but if the protrusion is short or almost nonexistent, a hanging rod is inserted into the roll core. The roll is hung with a sling. A considerable amount of work is required for stacking and removing rolls on pallets.
[0008]
Packing of medium to large rolls is heavy, and requires two people to support a pair of receiving materials on a pallet, and the other person unloads the rolls that have been lifted, which is not a labor saving operation.
[0009]
Smaller and lighter ones can be stacked in several stages on a pallet by providing a fitting part on the receiving material itself and fitting the receiving material up and down. It is dangerous to provide a fitting portion on the receiving material itself, fit it up and down, and stack it on a pallet in several stages because a shift during transportation is expected. In such a case, a cardboard case or a wooden box is required.
[0010]
For large rolls stacked on one pallet in units of one roll, if the receiving material seems to be insufficiently fixed, it can be stored in a combination of a wooden receiving material and a cardboard case or in a wooden box. In many cases, paper powder and wood powder are regarded as problems.
[0011]
Currently used receiving materials have the following problems. Wood cut products have problems of heavy, mold, sasacre, rot, and deformation. The plastic injection molded product has problems such as being easily stained due to the rib structure, difficult to clean, heavy and expensive. Corrugated products have problems such as durability, hygroscopicity, less reuse, and paper residue. Iron plates have problems such as heavy weight and rust.
[0012]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, as in the first to sixth inventions, fixing the four corners of a pair of receiving members with four rods at a glance solves various problems of the present invention. Found that it can be solved. In other words, if a pair of receiving members, which are not bent and do not expand and contract, are used to maintain an appropriate interval, the problem of over-tightening by the PP band can be solved, and the complicated work of binding by the PP band can be eliminated. Is done. Further, since the rod can be reused, dust of the binding band such as the PP band is not generated.
[0013]
Until now, the lifting and hanging of heavy rolls has been based on the shaft core protruding at both ends of the roll or the hanging rod passed through the shaft core, but if the load of a small to medium-sized roll is the rod body of the present invention. Can be directly lifted, and cumbersome operations such as stacking and storing on a pallet and taking out a small number of rolls from the pallet can be greatly reduced.
[0014]
A large roll requires two people to support a heavy receiving material and one person to suspend it, for a total of three people. By using a rod, the receiving material can be temporarily installed on a pallet. In this case, four rods may be used for temporary installation, but the lower corner of the receiving member may be temporarily installed using only two rods. Here, if a large roll is suspended and supported by a hanging receiving member, and the remaining two rods are loaded, one person can work.
[0015]
Further, even with a large roll, the pair of receiving members is fixed more firmly than the binding with the PP band by the rod, so that the cardboard case and the wooden box can be omitted.
[0016]
The scroll transporting material according to the first invention comprises a pair of receiving members for receiving and supporting both ends of the shaft core and suspending and supporting the scroll, and a rod body for fixing the pair of receiving members. Although the present invention is not limited to any fixing method and is characterized by a structure in which it is fixed by a body, the second to fifth inventions are intended to realize a concrete and effective method of fixing the rod and the receiving material. It is a form of transportation material. That is, the second invention clarifies the location where the rod is fixed and the number of rods, and the four corresponding corners of a pair of receiving members are fixed with four rods. I have found it to be the most effective. According to a third aspect of the present invention, in order to simplify the work of mounting the rod, a cutout groove for connection capable of loading the rod from the outside is formed on the outer portion of the receiving member. There is an advantage that the rod can be attached to the outside of the receiving member from the side and above the receiving member without changing the interval between the pair of receiving members. A fourth aspect of the present invention resides in that a falling-off restricting portion is formed in a cutout groove of a receiving member in order to prevent the rod from dropping from the receiving member due to vibration during transportation. Specifically, the present invention is to provide a structure in which the notch groove is curved toward the back. According to a fifth aspect of the present invention, the rod is provided with a length adjusting means. Even if the winding width of the roll changes, other materials can be used as they are simply by changing the length of the rod. Waste was eliminated, and material management was simplified. Even if the rod does not have a length adjusting means, or if a rod having a required length is prepared in advance, this advantage can be utilized. In a sixth aspect of the present invention, a pair of stopping portions are provided at both ends of the rod body at intervals corresponding to the thickness of the receiving member, and both stopping portions are arranged on both sides in the thickness direction of the receiving member. The movement of the rod body in the axial direction can be restrained, whereby both the opening and the narrowing of the pair of receiving members can be restrained.
[0017]
The seventh invention is designed to fix the receiving member as a rod, and a small-to-medium-sized roll can be stably lifted using the rod. A joint jig for joining the edges to enable stacking is also used. As a result, even if the receiving materials are stacked in multiple stages, they do not fall off due to vibration during transportation, and the conventionally used cardboard cases and wooden boxes can be omitted. In addition, medium-sized and relatively light rolls, which were stacked in units of one roll on one pallet, can be stacked with the connecting jig in this way, so that the second and subsequent pallets can be omitted. Increase efficiency.
[0018]
According to an eighth aspect of the present invention, the receiving material is made of a beaded polypropylene foam. Wood cut products have problems of heavy, mold, sasacre, rot, and deformation. Plastic injection molded articles have problems such as being easily soiled, difficult to clean, heavy, and extremely expensive in mold production. Corrugated products have problems such as durability, hygroscopicity, less reuse, and paper residue. Iron plates have problems such as heavy weight and rust. The bead-method expanded polypropylene of the eighth invention is represented by a method for producing bead-method expanded polystyrene (styrene foam). Pre-expanded particulate pre-expanded particles are filled in a mold having a predetermined shape and heated. This is a method for producing a foam, in which a second expansion is caused to occur, and the particles are mutually fused without any space, and then cooled to obtain a molded article in the shape of a mold. Pressurized steam is usually used as a heating medium. By adopting the bead-method foamed polypropylene, the durability, cushioning property, lightness, non-staining property, washability and non-water absorption are greatly improved. Even better, since the bead-method foamed polypropylene is molded in a mold, it is easy to shape and the holes, U holes and notched grooves of the receiving material of the present invention can be manufactured without post-processing.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a material for transporting a scroll according to the present invention will be described with reference to the drawings, taking an embodiment of a roll-shaped film as an example.
[0020]
1 to 3 show one example of the conventional method. FIG. 1 is a separate view of various parts of a transport material for suspending and supporting a roll 2 as a scroll on a pair of receiving members 9. FIG. 2 is a perspective view in which they are assembled and bound by a PP (polypropylene) band 4. The binding of the PP band 4 may be double or triple, and may be passed through the axis. FIG. 3 is a sectional view of FIG. The hole provided in the center of the receiving member 9 shown here is a U-shaped one open side, but may be a round shape, and may support the axis of the roll 2 directly or via the washer 3 at the bottom of the hole. Any shape may be used.
[0021]
4 to 6 show one example of the present invention. FIG. 4 is a separate view of various parts of the transport material according to the present invention in which a pair of receiving materials 1 suspends and supports a roll 2 as a roll. FIG. 5 is a perspective view in which they are assembled and fixed with a rod 5. FIG. 6 is an oblique sectional view of FIG. The difference from the conventional example is that the receiving member 1 is provided with the notch grooves 6 at the four corners, and four rods 5 are introduced.
[0022]
The receiving material 1 can be made of a wood-based cut product, a plastic injection-molded product, a corrugated cardboard product, an iron plate, or the like, but is durable, cushioning, lightweight, non-staining, washable, and non-water absorbing. It is composed of a plate-like member made of a polyolefin resin molded by a bead method because of its excellent properties and the like. Specific materials include polypropylene, high-density polyethylene, medium-density polyethylene, low-density polyethylene, ethylene-vinyl acetate copolymer, and the like. Among them, polypropylene, which has better strength and thermal dimensional change than polyethylene, is preferable. However, the term "polypropylene" as used herein includes those in which a small amount (1 to 5%) of ethylene or butene is copolymerized in order to improve moldability.
[0023]
When the density of the foamed polypropylene exceeds 300 g / L, the load-bearing performance increases, but it becomes expensive. When the density is less than 60 g / L, the load-bearing performance is greatly reduced and the material is not suitable as the receiving material 1. , Preferably 90 to 180 g / L. By setting as described above, it is possible to realize a receiving material having excellent load-bearing performance while suppressing an increase in the manufacturing cost and weight of the receiving material 1.
[0024]
An antistatic treatment may be performed during the manufacturing process of the receiving material 1. Specifically, the antistatic agent is melt-kneaded in the production step of unexpanded particles (called a mini-pellet, which is a string-shaped melt-extruded product cut into strips), which is the first step in the production process of the bead method expanded polyolefin. The antistatic agent is attached to the surface of the receiving material 1 formed in the final step by a method such as dipping. With such a configuration, the receiving material 1 is provided with antistatic performance, and the adhesion of dust to the receiving material 1 due to static electricity can be suppressed. As a result, contamination of the roll 2 can be prevented. As the antistatic agent, fatty acid amide type, fatty acid ester type, alkylsulfonic acid type and the like can be suitably used.
[0025]
In addition, a sheet member made of a low-foam extruded sheet such as polypropylene or a punched product of corrugated cardboard is arranged between the product part of the roll 2 and the receiving material 1 so as to further reduce the frictional resistance and prevent the receiving material 1 from being stained. You may prevent it from adhering to a product part.
[0026]
FIG. 7 shows a large roll in which both ends of a hanging rod 8 are suspended by a sling 7 by temporarily suspending and suspending the suspension using two rods 5 without the need for an operator to support the receiving member 1 for the large roll. It is a figure in the middle of suspending and supporting. This has made it possible to reduce the number of workers.
[0027]
FIG. 8 shows an example of the arrangement of the large rolls 2 according to the conventional method. As shown in FIG. 8, some of the large rolls 2, which are considered to be insufficiently fixed even when bound with the wooden receiving material 9 and the PP band 4, are housed in a cardboard case 10. On the other hand, FIG. 9 shows an example in which the cardboard case and the wooden box can be omitted as a result of the fixing by the rod body 5 of the present invention and the fixing being stronger than the binding with the PP band 4.
[0028]
The rod 5 can be fixed to the receiving member 1 by simply making a round hole in the corner of the receiving member 1 and inserting and fixing the rod into this hole, as shown in three examples in FIG. The work is simplified by forming the cutout groove 6 on the outer side of the receiving member 1 and mounting the rod 5. The bent notch grooves 6 provided on each side of the receiving member 1 in FIG. 10B and two on each side on the lower side in FIG. 10C prevent the rod 5 from falling off from the back according to the present invention. This is a shape showing an example of the drop-off restricting portion for restricting, and any other shape may be used as long as it can restrict the drop-off of the rod 5. As shown in FIG. 10C, the shape and arrangement of the cutout grooves 6 are determined as appropriate. In addition, since the falling-off restricting portion that controls the falling off of the rod 5 can prevent the rod from coming off during transportation, in the embodiment, not in FIG. 10A but in FIGS. 10B and 10C. The shape was adopted.
[0029]
FIG. 11 is a cross-sectional view showing an example of a rod in which the rod 5 is provided with a length adjusting means. In this example, two rods having a right-hand thread and a left-hand thread in the center part 11 of the rod are screwed into a pipe having a corresponding female thread to form one rod. The rod expands and contracts when the pipe is rotated. The length adjusting means is not limited to the present invention, and may be any number.
[0030]
An example in which a pair of flange-shaped stopping portions 12 are provided at both ends of the rod body 5 shown in FIG. 12 at intervals corresponding to the thickness of the receiving material 1 is shown. In the embodiment of the present invention, a steel rod body 5 coated with an AAS resin and having both ends formed with a pair of ABS resin stopping members formed with a pair of stopping parts 12 is fixed with an adhesive. It is. The material, shape, and structure of the rod 5 and the restraining member are not limited and may be various. By arranging the two stopping portions 12 on both sides of the receiving member 1 in the thickness direction, the movement of the rod with respect to the receiving member 1 in the axial direction could be suppressed. The stopper 12 may have any external shape. Further, it may be formed integrally with the rod 5.
[0031]
FIG. 13 shows an example of a connection jig 13 which connects the upper and lower edges of the receiving material 1 to enable stacking. In the embodiment of the present invention, the H-shaped cross section made of ABS is used. However, the material, shape and structure of the connecting jig are not limited because of various ideas. By the connecting jig 13, even if the receiving materials 1 are stacked in multiple stages, they do not slip off due to vibration during transportation, and a conventionally used cardboard case or wooden box can be omitted. That is, the cardboard box was omitted because the roll 2 stored in the cardboard case 10 as shown in FIG. 14 was stably stacked by the connecting jig 13 as shown in FIG. Although not illustrated in the drawing, what has been stacked in units of one roll of one pallet until now can be stacked by the connecting jig 13 in this manner, so that the second and subsequent pallets can be omitted. The loading efficiency could be improved.
[0032]
Table 1 shows a comparison between the various receiving materials used so far and those made of bead-method foamed polypropylene, which shows that bead-method foamed polypropylene is superior. As an example, the receiving material shown in FIG. 9 and FIG. 15 was manufactured using a bead method foamed polypropylene having a density of 180 kg / m ³ by a mold.
[0033]
[Table 1]

[0034]
Instead of the roll 2, a long band such as a sheet or a film as a product part, or a long band such as a thread or a rope is provided on a hollow pipe-shaped core made of paper, metal, or synthetic resin. The present invention can be similarly applied to a roll in which a cord is wound in a roll shape, a coil shape, a bobbin shape, a cheese shape, or the like.
[0035]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, since a scroll can be firmly and simply fixed with a receiving material and a rod, the binding material used conventionally, such as a PP band, can be abolished, and a cardboard case, a wooden box, etc. can be omitted in a large roll. In addition, since small-to-medium-sized rolls can be stacked in multiple stages using jigs for vertically connecting the receiving members, materials for transporting scrolls such as cardboard cases and wooden boxes can be eliminated. Furthermore, since the rod can be temporarily provided with a receiving material, the work of suspending and supporting the large-sized roll with the receiving material is labor-saving. In addition, if a receiving material made of bead-method foamed polypropylene is used, durability, cushioning property, lightness, non-staining property, cleaning property and non-water absorbing property are greatly improved.
