Description

  The present invention relates to a load fixing tool. More specifically, the present invention relates to a load fixing device that can prevent a collapse of a load by wrapping a load loaded in a plurality of stages with a single sheet and that has excellent work efficiency. .

  In general, in order to improve workability and save space in a storage place, the load is carried by loading the load on a pallet or cart for loading and unloading in several stages. In this case, unless the collapse of the load is prevented by some method, the transfer operation is interrupted due to the collapse of the load, the work efficiency is remarkably lowered, and further, the product is damaged. In order to prevent the collapse of the load, a method is known in which a load loaded on a pallet is wrapped and conveyed by a stretch film, and then the stretch film is peeled off and the load is lowered from the pallet.

  However, in the method of preventing load collapse using a stretch film, the peeled stretch film cannot be reused, resulting in a waste of cost and resources. Furthermore, since the discarded stretch film accumulates without being decomposed, a lot of disposal sites are required, which becomes a problem as industrial waste. On the other hand, when incinerating a stretch film, the human body may be adversely affected by gas at the time of incineration, which is a health and environmental problem. In addition, the incineration of stretch film runs counter to the currents while carbon dioxide emission regulations are a global requirement. In addition, when a stretch film is used, it is necessary to wind and fix the baggage around the baggage many times, and the work is extremely complicated.

  In order to solve the above problems, many belt-shaped load fixing devices have been proposed. For example, Patent Literature 1 describes a belt that is wound around the outer peripheral surface of a load loaded on a pallet to prevent the collapse of the load. This load collapse prevention belt is composed of a belt main body, a through ring (belt passing portion) attached to the base end side of the belt main body, and a hook-and-loop fastener attached to one side of the belt main body from the leading end toward the center. (Male) and a hook-and-loop fastener (female). The load collapse prevention belt holds the outer peripheral surface of the load by passing the pull-out end through the through ring, then pulling the pull-out end and turning it back to engage the male and female of the hook-and-loop fastener. However, since this load collapse prevention belt has a narrow width, it cannot prevent the load collapse of the load loaded in several stages, and a plurality of belts must be wound around the load separately.

  On the other hand, Patent Document 2 describes a wide belt (sheet) for preventing load collapse. According to such a sheet, it is possible to prevent the collapse of the load by winding the load loaded in several stages with one sheet. However, since such a sheet requires a plurality of hooking members, the winding work efficiency is very poor.

In addition, in all of the above prior arts, the position of the belt fasteners (for example, the through ring and the hooking member) is shifted depending on the winding method. Will be located. As a result, the belt may not be properly suspended or it may be necessary to rewind. Further, when the fastener is positioned at the corner of the luggage, the adjacent luggage (load) may be damaged or the loads may be caught.

  According to the present invention, by providing the taper-shaped relay portion whose width narrows from the belt-shaped sheet toward the tightening portion, the pulling force when tightening the load with the load fixing device is very good, and the entire width of the belt-shaped sheet is It is transmitted to. As a result, a very good binding force can be obtained and the collapse of the load can be prevented very well. In addition, by providing the temporary fixing part at a predetermined position from the end of the belt-like sheet tightening part passing part side, if the temporary fixing part is sandwiched between the loads on the end of the pallet, the belt-like sheet is placed on the outer periphery of the load. When wound around the part, the tightening part passing part is automatically positioned at the center of one side of the pallet. Therefore, there is no need to adjust the position while winding the sheet, or to rewind the sheet when the tightening position comes to the corner of the pallet. As a result, the working efficiency is extremely excellent. Furthermore, if the tightening section through section is located at the corner of the load, adjacent loads may be damaged or the loads may be caught. Therefore, it is possible to avoid the above problems. In this way, it is possible to provide a load fixing tool that can prevent a collapse of a load by winding a load loaded in a plurality of stages with a single sheet and that is extremely excellent in work efficiency. it can.

  FIG. 1 is a plan view showing a surface of a load fixing device according to a preferred embodiment of the present invention. FIG. 2 is a plan view showing a back surface of the load fixing tool of FIG. The load fixing device 100 includes, for example, a belt-like sheet 10 wound around an outer peripheral portion of a load (hereinafter also referred to as a load) loaded in a plurality of stages on a pallet or a carriage. The belt-like sheet 10 has a length suitable for winding and binding around the outer periphery of the load. For example, when a load is loaded on a pallet having a side of 110 cm, the length L1 of the belt-like sheet is preferably 400 to 440 cm. With such a length, a very good binding force can be obtained when the bag is wrapped around a load and tightened. Furthermore, the belt-like sheet 10 has an appropriate width for holding a load loaded in a plurality of stages with a single sheet. For example, the width W1 of the belt-like sheet is preferably 40 to 100 cm. The belt-like sheet is made of any appropriate material. Specific examples of the material include polyester (for example, normal polyester, recycled PET), nylon, and biodegradable resin (for example, polylactic acid derived from corn). The belt-like sheet is typically composed of a thick polyester sheet as a whole. With this configuration, since static electricity is hardly generated, there is little adverse effect on the load, and the durability is excellent. For example, a load fixture using such a belt-like sheet can be reused 1000 times or more. In preferable embodiment, the back surface of the strip | belt-shaped sheet | seat 10 is comprised with cotton cloth. With this configuration, generation of static electricity can be further suppressed. In addition, the strip | belt-shaped sheet | seat 10 may be comprised with one sheet | seat as mentioned above, and may interpose the part which consists of an elastic material in the intermediate part of the above sheets. By adopting such a configuration, the workability of winding around the luggage becomes easier. The portion made of an elastic material is made of, for example, a fabric woven with polyurethane elastic yarn. Furthermore, the belt-like sheet may be provided with a pocket for attaching a tag as required, and may be configured so that the contents of the load can be confirmed. Examples of the configuration for confirming the contents of the load include, for example, forming at least a part of the belt-like sheet with a transparent material or a mesh fabric, and providing an opening serving as a confirmation window in a part of the belt-like sheet. .

  Furthermore, the load fixing device 100 includes a relay unit 20 that continuously extends from one end of the belt-like sheet 10. The relay part 20 has a tapered shape with a width that decreases from the belt-like sheet 10 toward the fastening part 30. By providing such a relay portion, the traction force when tightening the load with the load fixing device is transmitted very well over the entire width direction of the belt-like sheet. As a result, a very good binding force can be obtained and the collapse of the load can be prevented very well. As the taper angle θ of the relay portion, any appropriate angle is adopted depending on the width of the belt-like sheet, the width of the fastening portion, the ratio of the width of the belt-like sheet and the fastening portion, and the like. In one embodiment, the taper angle θ is preferably 120 ° to 160 °, more preferably 130 ° to 150 °. By providing the relay portion having a taper angle in such a range, the propagation of the traction force to the belt-like sheet when tightening the load is further improved, and as a result, the binding force is further improved. The material of the relay unit 20 is the same as that of the belt-like sheet 10.

  Furthermore, the load fixing device 100 includes a fastening portion 30 that extends continuously from the relay portion 20. The tightening portion 30 has an engaging means 31. In one embodiment, the engaging means 31 is composed of hook and loop fasteners 32 and 33 that can be engaged with each other. In the illustrated example, a hook-and-loop fastener (male) 32 is provided at the most distal portion of the tightening portion, and a hook-and-loop fastener (female) 33 is provided from the most distal portion toward the relay portion 20. Preferably, the hook-and-loop fastener is configured by weaving conductive fibers. With such a configuration, it is possible to suppress the generation of static electricity when the load fixing tool is removed from the luggage, so that adverse effects on the load can be reduced. The width W2 of the tightening portion is preferably 30% to 80%, more preferably 30% to 50% of the width W1 of the belt-like sheet. If W2 / W1 is such a ratio, a very excellent binding force can be obtained. The length L2 of the tightening portion can be appropriately set according to the pallet size, the length L1 of the belt-like sheet, the taper angle θ, and the like. For example, when a load is loaded on a pallet having a side of 110 cm, the length L2 of the tightening portion is preferably 30 to 50 cm. With such a length, a very good binding force can be obtained when the bag is wrapped around a load and tightened. In the illustrated example, the foremost portion (the portion where the hook-and-loop fastener 32 is provided) of the tightening portion is configured as two folded portions, and a glass fiber rod is included and held in the folded portion. With this configuration, a pull ring is formed at the tip of the tightening portion, so that workability during tightening is improved.

  Furthermore, the load fixing device 100 has a tightening portion passing portion 40 at the other end portion of the belt-like sheet 10 (the end portion on the side where the relay portion 20 and the tightening portion 30 are not provided). The tightening portion passing portion 40 is configured, for example, by providing folded portions 41 and 42 at the upper and lower end portions of the belt-like sheet 10 and holding and holding a glass fiber rod 43 in the folded portion. A through hole 44 is defined between the end of the belt-like sheet and the glass fiber rod. The belt-like sheet is wound around the outer periphery of the load, passed through the tightening portion through the through hole 44, then folded back and tightened, and the hook-and-loop fasteners 32 and 33 are engaged to bind the load and prevent the collapse of the load. In addition, you may comprise the fastening part passage part 40 as a through ring like the buckle of a normal belt. Furthermore, the rod 43 may be made of aluminum, stainless steel, or carbon fiber.

  Furthermore, the load fixing device 100 has a temporary fixing portion 50. The temporary fixing portion 50 is provided so as to extend in the width direction from the belt-like sheet 10. The temporary fix | stop part 50 is provided in the arbitrary appropriate positions of the longitudinal direction of a strip | belt-shaped sheet | seat. According to such a structure, it can wind, hold | maintaining the upper part of a strip | belt-shaped sheet | seat in a suitable position by pinching | interposing a temporary fix | stop part between loads. Therefore, the work of one person holding the upper part of the belt-like sheet and the other person winding the sheet around the load is avoided. That is, work by one person is possible and workability can be greatly improved. Preferably, the temporary fixing part 50 is 25% to 75% of one side length (substantially one side length of a pallet or a carriage) from the end of the belt-like sheet 10 on the tightening part passage part 40 side. In the position. More preferably, it is provided at a position of 35% to 65%. According to such a configuration, when the belt-like sheet is wound around the outer peripheral portion of the load by sandwiching the temporary fixing portion between the loads at the end of the pallet, the tightening portion passage portion 40 (through hole 44) is automatically set. Thus, it is located at the center of one side of the pallet or the like. Therefore, it is not necessary to adjust the position while winding the sheet, or to rewind the sheet when the tightening position comes to the corner of the pallet or the like. As a result, the workability of winding can be further greatly improved. Furthermore, if the tightening section through section is located at the corner of the load, adjacent loads may be damaged or the loads may be caught. Therefore, it is possible to avoid the above problems. In this specification, “between the loads at the end of the pallet” means a package and a package located at the corners of the four corners of the loaded package as shown in FIGS. 3 (a) and 3 (b). Means between. Therefore, the “pallet end portion” includes the vicinity of the pallet end portion when the load is loaded out of the pallet and / or when the pallet is left over. Preferably, the temporary fixing portion is made of a non-slip material or is subjected to a non-slip treatment. A specific example of such a material is a styrene elastomer nonwoven fabric. As a specific example of the anti-slip process, the rubber sheet 51 is attached to the tip of the temporary fixing part.

  If necessary, the load fixing device 100 further includes a storage binding member 60. The storage bundling member 60 is provided at any appropriate position. In one embodiment, the storage bundling member 60 is attached to the glass fiber rod 43 of the tightening portion passing portion 40. The storage binding member 60 includes, for example, a hook-and-loop fastener (male) 61 and a hook-and-loop fastener (female) 62. According to such a configuration, when the load fixing tool is collected after use, it can be bundled in a rolled state, and therefore the load fixing tool can be transported and collected in a compact state.

  Hereinafter, with reference to FIG. 3 (a)-(d), the usage method of the load fixing tool of this invention is demonstrated. First, as shown to Fig.3 (a), the temporary fix | stop part 50 is inserted | pinched between the load of a pallet edge part. Next, as shown in FIG. 3B, while maintaining the position of the temporary fixing portion (usually, the temporary fixing portion is maintained at the initial position without performing any special operation), the belt-like sheet 10 is Wrap around the load. Further, as shown in FIG. 3C, the tightening portion 30 is passed through the through hole 44 of the tightening portion passing portion 40, and folded to tighten the load. Here, according to the present invention, the fastening portion passing portion 40 is automatically positioned at the center of one side of the pallet by positioning the temporary fixing portion 50 at the end of the pallet. Therefore, there is no need to adjust the position while winding the sheet, or to rewind the sheet when the tightening position comes to the corner of the pallet. By engaging the surface fasteners 32 and 33 in this state, the load is bound as shown in FIG.

  The load fixing device of the present invention is suitably used for preventing load collapse of a load loaded in a plurality of stages on a pallet or a carriage. Furthermore, since the load fixing device of the present invention is reusable, there is no need for disposal / incineration unlike a stretch film. Therefore, it is also effective for environmental conservation such as reducing greenhouse gas emissions.
