Description

  INDUSTRIAL APPLICABILITY The present invention is used when a sheet, a film, a filamentous material or the like is loaded on a roll, a coil, a bobbin, or a cheese roll, and is transported sideways, and is particularly suitably used as a transport material for roll products such as a film. It relates to materials for scroll transportation.

Conventionally, as a packing method when transporting a roll sideways, a method of grounding and fixing the scroll to a rug or a pad on a pallet (see, for example, Patent Document 1) and a suspended suspension that does not contact the surface of the scroll. There is a mold method (for example, see Patent Document 2), but the present invention belongs to the latter, and is a circular or U-shaped one provided at the center of a pair of rectangular plates (receiving materials) larger than the diameter of the scroll. A method of fixing the shaft core (paper tube, etc.) directly into the hole or by inserting a washer and supporting it in suspension, and then tightening and fixing it around the center of the scroll or the axis of the scroll with a binding band (PP band, etc.) in the horizontal direction. Is widely practiced. There are various types of roll products such as films, ranging from small (load: 10 to 100 kg), medium (100 to 350 kg), and large (350 to 1200 kg). Accordingly, the size of the receiving material is approximately 200 mm to 1200 mm square. . There are various loading methods on these pallets, and they are stored in a storage case (corrugated cardboard case, wooden box, etc.) and loaded on the pallet in one or more stages. A fitting part may be provided and upper and lower receiving materials may be fitted and stacked on the pallet in several stages. In the case of medium to large and heavy rolls, place a receiving material on the pallet, and lower the rolls that are lifted using the protrusions at both ends of the rolls or in the roll cores, and support them suspended and secured with a binding band. However, it requires a large number of workers and is a large-scale work. Since the stacking is heavy, they are stacked in units of one roll on one pallet.
There are various problems in the materials of the receiving materials that are currently used, such as wooden cutting products, plastic injection molded products, corrugated cardboard products, and iron plates.

JP-A-8-2526 (2nd page, 3rd page, FIG. 1 and FIG. 2) Japanese Patent Laid-Open No. 10-45163 (second page, third page, FIGS. 1 and 3)

  The widely used method of fixing the backing material and the roll with a binding band such as a PP band tends to overtighten the binding band to prevent loosening during the transportation of the binding band. It may bend to the roll side, and the end face of the roll product such as a film may be damaged while the receiving material is damaged. Also, the work itself of fixing the PP band by making a round is complicated.

  Further, the PP band used for binding is garbage after the roll is taken out, leaving the consumer side the trouble of disposal. Furthermore, since cardboard cases and wooden boxes are not reused, they become business waste after use.

  The use of cardboard cases or wooden boxes is preferable because paper dust and wood powder are generated by rubbing when storing, storing, transporting, and opening the roll, and this may adhere to the roll product due to static electricity, etc., causing film contamination. Absent.

  Since a heavy roll cannot be lifted by human power, it is generally lifted by hanging a sling on the shaft core that protrudes from both ends of the roll. The roll is lifted with a sling. It is a considerable work by stacking and removing rolls on a pallet.

  Packing of medium-sized to large-sized rolls is heavy, and is not labor-saving because it is a three-person operation in which a pair of receiving materials are supported by two people on a pallet and a roll lifted by another person is taken down.

  Small and lightweight ones can be stacked on the pallet by fitting the receiving material up and down to fit the receiving material up and down. It is dangerous to provide a fitting part in the receiving material itself and fit it up and down and stack it on the pallet in several stages because a deviation during transportation is expected. In such a case, a cardboard case and a wooden box are required.

  In addition, even in the case of large rolls stacked on a pallet in units of one roll, if the receiving material seems to be insufficiently fixed, it can be stored in a wooden box combination or wooden box. In many cases, paper powder and wood powder are regarded as problems.

  The material of the receiving material currently used has the following problems. Wood-based processed products have problems of heavy, mold, crust, rot, and deformation. Plastic injection molded products have problems such as being easily soiled due to the rib structure, difficult to clean, heavy and expensive. Corrugated cardboard products have problems such as durability, hygroscopicity, low number of reuses, and paper wrinkles. Iron plates have problems such as being heavy and rusty.

  As a result of intensive studies to solve the above problems, as in the first to sixth inventions, by fixing the four corners of the pair of receiving members with four rods, the problems of the present invention are enumerated. I found that it can be solved. In other words, if a rod that does not bend and stretch / contract to maintain a suitable interval is used for a pair of receiving materials, the problem of over-tightening due to the PP band can be solved, and free from complicated binding work with the PP band. Is done. Further, since the rod body can be reused, it does not generate trash in a binding band such as a PP band.

  Up to now, the lifting and suspending of heavy rolls has been based on the shaft core protruding from both ends of the roll or the suspension rod passed through the shaft core. However, if the load is a small to medium roll, the rod of the present invention Can be lifted directly, and cumbersome operations such as stacking and storing on a pallet and taking out a small number of rolls from the pallet are greatly reduced.

  Large rolls were carried out by two people for supporting heavy receiving materials and one for hanging, a total of three people, but by using a bar, the receiving material can be temporarily placed on a pallet. In this case, although it may be temporarily set with four rods, the lower corner of the receiving material can be temporarily set with only two rods. If a large roll is suspended and supported on a receiving material, and the remaining two rods are loaded, one person can work.

  Furthermore, as a result of fixing a pair of receiving materials even with a large roll to be stronger than binding with a PP band by a stick, a cardboard case and a wooden box can be omitted.

The material for transporting a scroll according to the first invention is a pair of receiving materials for receiving the both ends of the shaft core and suspending and supporting the scroll, and a pair made of a bead method foamed polypropylene having a density of 60 to 300 g / L. When, which has a rod for fixing it, as a feature configuration for fixing the receiving member with a stick body, but not deny any fixing method, the invention of the second to sixth rod In order to make the fixing method of a body and a receiving material concrete and effective, the form of the material for scroll transportation was devised. 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 by four rods. It has been found that it is the most effective. According to a third aspect of the present invention, there is provided a connection notch groove in which the rod body can be loaded from the outside in the outer portion of the receiving member in order to simplify the mounting of the rod body. There is an advantage that the rod body can be mounted on the outer side of the receiving material from the side of the receiving material and from the upper side without changing the interval between the pair of receiving materials. According to a fourth aspect of the present invention, in order to prevent the rod body from dropping from the receiving material due to vibration during transportation, a dropping restricting portion is formed in the notch groove of the receiving material. Specifically, the notch groove has a curved structure as it goes deeper. In the fifth aspect of the invention, the rod body is provided with a length adjusting means, so that even if the roll width of the roll is changed, other materials can be used as they are simply by changing the length of the rod body. Waste management has been eliminated, making material management easier. Moreover, even if the rod body does not have a length adjusting means or a rod body having a necessary length is prepared in advance, this merit can be utilized. According to a sixth aspect of the present invention, a pair of restraining portions are provided at both ends of the rod body with an interval corresponding to the thickness of the receiving material, and both restraining portions are disposed on both sides in the thickness direction of the receiving material. Since the movement of the rod body in the axial direction can be restrained, it is possible to restrain both the opening and the narrowing of the gap between the pair of receiving members.

  The seventh aspect of the invention was devised because the receiving member is fixed to a rod, and the rod is used to stably lift a small to medium-sized roll. It is a combination of connecting jigs that can be stacked by connecting edges. As a result, the cardboard case and the wooden box that have been used in the past can be omitted without causing a slippage due to vibration during transportation even when the receiving materials are stacked in multiple stages. In addition, if the medium-sized and relatively lighter rolls are stacked on one pallet in units of one roll, the pallets in the second and subsequent stages can be omitted by stacking them with the connecting jig in this way. Increases efficiency.

The accepted material, can be suitably adopted as the beads method expanded polypropylene. In other words, wood-based cut products have problems of being heavy, mold, crust, rot, and deformation. Plastic injection-molded products have problems such as being easily soiled, difficult to clean, heavy, and very expensive to produce a mold. Corrugated cardboard products have problems such as durability, hygroscopicity, low frequency of reuse, and paper wrinkles. Iron plates have problems such as being heavy and rusty . The bi chromatography's method foamed polypropylene, represented by the manufacture method of bead method expanded polystyrene (Styrofoam), the pre-foamed particulate pre-expanded particles were filled in a mold of a predetermined shape, heated 2 This is a foam production method in which the second expansion of the foam is caused, the particles are mutually fused without a space, and cooled to obtain a molded product according to the shape of the mold. Usually, pressurized steam is used as the heating medium. By adopting this beaded foamed polypropylene, durability, buffering property, light weight, non-contaminating property, detergency, and non-absorbing property are greatly improved. Even better, since the bead-processed polypropylene is molded with a mold, it is easy to form and can be manufactured without post-processing the holes, U-holes and notched grooves of the receiving material of the present invention.
In an eighth invention, the receiving material is subjected to an antistatic treatment.

  According to the present invention, since the scroll can be firmly and easily fixed between the receiving member and the rod, the conventionally used binding material such as PP band can be eliminated, and the cardboard case, the wooden box, etc. can be omitted in the large roll. Also, small to medium-sized rolls can be stacked in multiple stages using a jig for connecting the receiving material up and down, so that materials for transporting scrolls such as cardboard cases and wooden boxes can be abolished. Furthermore, since the rod can temporarily receive the receiving material, the work of supporting the suspension with the receiving material of the large roll has been saved. In addition, if a receiving material made of beaded foamed polypropylene is used, durability, buffering properties, light weight, non-contaminating properties, cleaning properties, and non-absorbing properties are greatly improved.

  Hereinafter, the embodiment of the material for transporting a scroll according to the present invention will be described with reference to the drawings, taking the embodiment of the roll film as an example.

  1-3 show an example of the conventional method. FIG. 1 is a separation diagram of various parts of a transportation material in which a roll 2 as a scroll is suspended and supported by a pair of receiving materials 9. FIG. 2 is a perspective view in which they are assembled and bound together by a PP (polypropylene) band 4. The binding of the PP band 4 may be double or triple, and may pass through the shaft core. FIG. 3 is a cross-sectional view of FIG. The hole provided in the center of the receiving material 9 shown here is U-shaped with one side released, but it may be round and supports the axis of the roll 2 directly or through the washer 3 at the bottom of the hole. Any shape is acceptable.

  4 to 6 show an example of the present invention. FIG. 4 is a separation diagram of various parts of the transportation material according to the present invention in which a roll 2 as a scroll is suspended and supported on a pair of receiving materials 1. FIG. 5 is a perspective view in which they are assembled and fixed by the rod 5. 6 is an oblique sectional view of FIG. The difference from the conventional example is that the notched grooves 6 are provided in the four corners of the receiving material 1 and that four rod bodies 5 are introduced.

  The receiving material 1 can be composed of a wood-based machined product, a plastic injection molded product, a corrugated cardboard product, an iron plate, etc., but is durable, cushioning, lightweight, non-contaminating, detergency, non-water absorbing Because of its excellent properties, it is composed of a plate-like member made of a polyolefin resin molded by a bead method. Specific examples of the material include polypropylene, high-density polyethylene, medium-density polyethylene, low-density polyethylene, and ethylene-vinyl acetate copolymer. Among them, polypropylene that is superior in strength and thermal dimensional change to polyethylene is preferable. However, the term “polypropylene” as used herein includes those obtained by copolymerizing a small amount (1 to 5%) of ethylene or butene for improving moldability.

  When the density of the expanded 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 lowered and is not suitable as the receiving material 1. , Preferably, it will be set to 90-180 g / L. By setting in this way, it is possible to realize a receiving material excellent in load bearing performance while suppressing an increase in manufacturing cost and weight of the receiving material 1.

  An antistatic treatment may be performed in the manufacturing process of the receiving material 1. Specifically, the antistatic agent is melted and kneaded at the manufacturing stage of unexpanded particles (called mini-pellets, which are obtained by cutting a string-like melt-extruded product into strips), which is the first step in the manufacturing process of the bead-processed polyolefin. The antistatic agent is attached to the surface of the receiving material 1 formed by the method or the final step by a method such as dipping. If comprised in this way, antistatic performance will be provided to the receiving material 1, the adhesion of the dust by the static electricity with respect to the receiving material 1 will be suppressed, and the contamination to the roll 2 can be prevented as a result. As the antistatic agent, fatty acid amides, fatty acid esters, alkyl sulfonic acids, and the like can be suitably used.

  In addition, a sheet member made of a low-foam extruded sheet such as polypropylene or a cardboard punched product is disposed between the product portion of the roll 2 and the backing material 1 to further reduce the frictional resistance, You may make it prevent adhering to a product part.

  FIG. 7 shows that a large roll in which both ends of a suspension bar 8 are lifted by a sling 7 is provided by temporarily using two rod bodies 5 without having to support the receiving material 1 for the large roll. FIG. As a result, the number of workers can be reduced.

  FIG. 8 shows an example of an arrangement example of the large roll 2 according to the conventional method. Among the large-sized rolls 2, those that are considered insufficiently fixed even if they are bound together with the wood-based receiving material 9 and the PP band 4 as shown in FIG. 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 by the PP band 4.

Fixing of the receiving member 1 of the rod 5 is opened just at the corner portion of the receiving member 1 round hole, although it is possible to be inserted City secured to the hole rod, 3 cases so in FIG. 10 Further, the work is simplified by forming the notch groove 6 in the outer portion of the receiving member 1 and mounting the rod body 5. 10 (b), two bent notches 6 on both sides of the receiving material 1 and FIG. 10 (c) on both lower sides prevent the rod body 5 from falling off from the back according to the present invention. It is the shape which showed one example of the drop-off control part to control, and it is sufficient if it is a shape which can control the drop-off of the rod body 5 with another shape. As shown in FIG. 10C, the shape and arrangement of the notch grooves 6 are appropriately determined. In addition, the drop-off restricting portion that restricts the drop-out of the rod body 5 can prevent the rod body from being removed during transportation. Therefore, in the embodiment, not in FIG. 10 (a) but in FIG. 10 (b) and FIG. 10 (c). Adopted the shape.

  FIG. 11 is a cross-sectional view showing an example of a rod body in which the rod body 5 is provided with length adjusting means. In this example, two rods having a right-hand thread and a left-hand screw are screwed into a pipe having a corresponding female thread at the center 11 of the rod body to form one rod body. If the pipe is rotated, the rod will expand and contract. There are various length adjusting means, not limited to this proposal.

  An example in which a pair of flange-like restraining 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 this embodiment, a steel rod body 5 coated with AAS resin is bonded to both ends of an ABS resin restraining member formed with a pair of restraining portions 12 by using an adhesive. It is. The material, shape, and structure of the rod body 5 and the restraining member are not limited and are conceivable. By disposing both the restraining portions 12 on both sides in the thickness direction of the receiving material 1, the movement of the rod body in the axial direction with respect to the receiving material 1 could be restrained. In addition, the stop part 12 can employ | adopt the thing of arbitrary external shapes. Further, it may be formed integrally with the rod 5.

  FIG. 13 shows an example of a connecting jig 13 that connects the upper and lower edges of the receiving material 1 to enable stacking. Although the embodiment of this example is made of ABS having an H-shaped cross section, the material, shape and structure of the connecting jig are not limited and are conceivable. The connecting jig 13 does not fall off due to vibration during transportation even when the receiving materials 1 are stacked in multiple stages, and the cardboard cases and wooden boxes that have been conventionally used can be omitted. That is, the corrugated cardboard is omitted because the roll 2 housed in the corrugated cardboard case 10 as shown in FIG. 14 can be stably loaded with the connecting jig 13 as shown in FIG. In addition, although not illustrated in the figure, the pallets in the second and subsequent stages can be omitted by stacking the pallets that have been stacked in units of one pallet with the connecting jig 13 in this way. It was also possible to increase loading efficiency.

Table 1 shows a comparison of various receiving materials that have been used so far and those made of beaded foamed polypropylene, showing that the beaded foamed polypropylene is superior. As an example, the receiving material shown in FIG. 9 and FIG. 15 was manufactured by a mold using a bead-method foamed polypropylene having a density of 180 kg / m ³ .

  In addition, instead of the roll 2, a hollow pipe-shaped core made of paper, metal or synthetic resin, a long strip such as a sheet or a film as a product part, or a long strip such as a thread or a rope The present invention can be similarly applied to a scroll in which a string-like material is wound in a roll shape, a coil shape, a bobbin shape, a cheese shape, or the like.
