Description

  The present invention relates to a load collapse prevention belt for loads on a pallet. Specifically, it has a sufficient strength and elasticity that can prevent the collapse of the luggage, and a stretchable part that facilitates the operation, and the transparency of the luggage surface that is covered with a belt can be seen through. A pallet that has air permeability that can reliably apply cold air to the part that is on the surface, and further prevents condensation on the belt part when it goes out of the cold place and allows the belt net surface to be printed. The present invention relates to a load collapse prevention belt.

  Resin-made and wooden pallets are mainly used as a platform for loading luggage for loading / unloading of luggage into / from the truck's cargo room and loading / unloading of cargo into / from the management warehouse, freezer compartment, and the like. A part or all of the luggage is fixed to each other so that the luggage placed on the pallet does not collapse and further does not protrude. The contents can be checked.

  In the past, the loaded luggage was wrapped and fixed with wrap film (also called stretch film). This method takes a lot of time to wrap the wrap film, is covered with a wrap film when the luggage is refrigerated or frozen, and has a low cooling efficiency because it is hard to cool, and the wrap film after use However, there is a big problem in the environment, such as the fact that it can't be reused and disposal takes a lot of time and money.

For this reason, in recent years, a belt for preventing load collapse has been proposed that can be used repeatedly and does not require time and effort for disposal (see Patent Document 1).
The thing disclosed by patent document 1 has a hook_and_loop | surface fastener in the both ends of the strip | belt body made with the elastic member, and the part to which each hook_and_loop | surface fastener is attached among the belt | band | zone is made with a non-stretchable member. Therefore, the binding property of the binding part is improved by preventing deformation such as the surface fastener undulating. All belts on the pallet are belted with hook-and-loop fasteners (see Patent Document 2), or parts of the baggage are partially fixed with hook-and-loop fasteners (see Patent Document 3), and the luggage on the pallet is fixed with belt-like sheets A belt (see Patent Documents 4 and 5) has been proposed. There were few such things for the above purpose. The present inventor has previously proposed in Japanese Patent Application No. 2005-89648 in order to solve these problems (see Patent Document 6), but some problems remain in stretchability, fixing method, and printability.

Japanese Patent No. 3551247 JP-A-11-11481 JP-A-10-324364 JP 2001-122265 A JP 2002-179132 A Japanese Patent Application No. 2005-89648

  Although the load collapse prevention belt described in Patent Document 1 has sufficient utility regarding the binding and fixing properties of the hook-and-loop fastener as described above, there are problems in the following points.

  First, although the material of the belt is a stretchable woven fabric made of resin fibers, it does not have transparency or ventilation. For this reason, since it is not possible to see through the part of the luggage surface covered with the belt, if there is a need to check various information such as the product name, weight, and lot number displayed on the luggage surface, the display unit When it was covered, the belt had to be moved and removed each time.

In addition, since cold air cannot be applied to the covered portion, the cold air is not good and there is a risk of causing unevenness in the frozen state. It is important that the belt itself requires cold air permeability.
In addition, condensation is likely to form on the belt when it is taken out of a cold place such as a freezer / refrigerator room. If the belt is dropped on the ground, dirt and sand will easily adhere to it, and it can be reused without washing. It is difficult to handle when removed. Alternatively, if the belt itself does not have a portion that contracts slightly, a force is required for tightening when binding and fixing.

  An object of the present invention is a load collapse prevention belt for preventing a collapse of a load, in which the portion of the surface of the load that is covered with the belt can be seen through, and cold air or the like is reliably applied to the covered portion. The net part has ventilation characteristics, and has weather resistance against temperature, can prevent condensation of the belt when going out of a cold place, and has some strength against pulling and impact In addition, the present invention provides a load collapse prevention belt made of a material having a shape that can be easily printed and printed on the net portion.

Means taken by the present invention to solve the above problems are as follows.
In order to prevent the cargo from collapsing on the pallet for cargo transportation, it is possible to demonstrate the transparency and ventilation of the cargo, and it can be fixed stably. A hook-and-loop double woven polyolefin resin net part that can be stretched in the longitudinal direction adjacent to the hook-and-loop fastener part, and a warp-knitted polyolefin resin that does not stretch in the longitudinal direction. It consists of a net part.
In the present invention, the pallet load collapse prevention belt has a width of 50 to 1500 mm, a total length of 3000 to 8000 mm, and the lengths of the hook-and-loop fastener portions at both ends are 100 to 700 mm, and can be expanded and contracted in the longitudinal direction. The net part of the woven double mesh polypropylene resin is 200 to 1000 mm. Generally, there are various pallets, but the circumference of the load is about 3 to 8 m. It is desirable that the hook-and-loop fastener of the fixing portion is short and strong and can be fixed with this length. Accordingly, the lengths of the hook-and-loop fasteners are 100 to 700 mm at both ends, respectively, and if it is more than that, it becomes poor in fluoroscopy. Also, a double mesh polypropylene net part of warp weaving is used to improve work efficiency due to the elasticity and shrinkage of the belt, but if this part is long, it will warp and become insufficiently fixed. If it is short, workability will be disrupted. Polyolein resin is effective as a material, but polypropylene is desirable in terms of strength and price.
The material for the net part made of polyolefin resin is polyethylene, polypropylene, and the thickness of the synthetic resin thread is 0.05 to 1 mm, and the width of the mesh (mesh size) is In the net part of the warp woven weave made of polyolefin resin, which is in the range of 1 to 10 mm and does not expand or contract in the longitudinal direction of the center part, the net-like band is a fibrous net made of polyethylene resin monoflamet yarn. The mesh of the net is in the range of 1 to 10 mm, and the specific gravity of the net is 0.1 to 0.8. The net part affects the overall weight, and it is required to be light and strong in terms of packing workability. Therefore, the specific gravity of the net is 0.1 to 0.8, and it is desirable that the strength is about 0.2 to 0.6. If the mesh size of the net is 1 mm or less, the air permeability and transparency are poor, and if it is 10 m or more, the strength as a net is lowered. Therefore, about 2-6 mm is preferable.
In the present invention, there are various methods for fixing the belt, but a hook-and-loop fastener is suitable for simplicity. The hook-and-loop fastener is a hook tape type, loop tape type, and a mixture of both. The hook and loop in the hook-and-loop fastener are mainly made of nylon, and a mixture of nylon and ester. It is a synthetic resin material having air permeability. The hook-and-loop fastener for the pallet load collapse prevention belt is used to firmly fix the belt, and a certain length and characteristics are important. A hook tape type mainly made of nylon resin is preferred. This hook-and-loop fastener has a good weaving method.
The warp-woven polyethylene resin net portion that does not stretch in the longitudinal direction has a surface shape that can be printed and printed on the net surface. The net shape of the net is uniform and the surface of the net of the net is in an appropriate surface state so that the company name, product name, promotional text, etc. can be printed on the transparent warp woven net at the center.
The polyolefin yarn net used in the present invention is a warp knitted fabric. This woven fabric is a woven fabric formed by loops that are continuous in the vertical direction, and is capable of forming a shrinking net. In particular, it is a high-strength cloth with no crimp on the warp and weft of polyolefin mono-fragment.
In the first invention,
It is equipped with a belt band made of weaving mesh with a mesh that can fully see and ventilate the baggage on the pallet, and this belt body is essentially in the longitudinal direction. A portion that does not have elasticity and has some elasticity in the width direction,
A portion having elasticity in the longitudinal direction is provided in the vicinity of the hook-and-loop fastener, and fastening means capable of adjusting and fixing the effective length when the belt band is wound is provided. Furthermore, in the operation, the pellet collapse prevention belt has a width of 50 to 1500 mm, a total length of 3000 to 8000 mm, a length of the hook-and-loop fastener at both ends is 100 to 700 mm, and a polyolefin yarn that can expand and contract in the longitudinal direction. A double woven net (for example, one woven with a Raschel weaving machine) has a warp knitted net portion of a belt band of 200 to 1000 mm.

In the second invention, the resin net portion is made of synthetic resin fibers, and the synthetic resin fibers are polyolefin-based polyethylene or polypropylene, and the synthetic resin threads are thick. The belt band is made of synthetic resin, and the width of the mesh (net mesh) is in the range of 1 to 10 mm. The net part has a specific gravity of 0.1 to 0.8.

In the third invention, the hook-and-loop fastener is a hook tape type, a loop tape type, and a mixed type thereof, and the hook and loop in the fastener are mainly composed of nylon and ester fibers. Fastener lining is breathable. At least one end side in the longitudinal direction of the band is provided with a handle member and means for preventing the width of the band from changing.

According to the fourth aspect of the invention, the warp-woven polyethylene resin net portion that does not expand and contract in the longitudinal direction is in a surface state that can be printed and printed on the surface of the net. The net shape of the net is uniform, and the net of the net is in an appropriate state so that the company name, product name, promotional text, etc. can be printed on the transparent warp knitted net in the center.
The length and length ratio of the main belt body of the belt is not particularly limited in the length direction and the length ratio of the length portion adjacent to the hook-and-loop fastener. However, the length is 200 mm to 1000 mm. However, it can be appropriately set within this range depending on the type and size of the package to be used.

  The material of the belt band is, for example, a synthetic resin such as polyethylene (PE) or polypropylene (PP). However, there are problems in the strength, transparency, stretchability, printability, etc. to prevent collapse of the load. If not, other materials can be used, but polyolefin resin is most effective. The fibers forming the belt band may be transparent or translucent, may be colored, and may be opaque if the mesh is sufficiently large. However, from the perspective and printability, transparent or translucent is preferable.

  The means to prevent the belt band width from changing is to prevent the band width from shrinking when the belt band is wrapped around a load and the end of the belt is pulled by holding the grip member. If it can be done, its shape and material are not particularly limited. It is enough to install it in one place.

(Function)
The operation of the load collapse prevention belt according to the present invention will be described. Here, each constituent element of the present invention will be described in association with the reference numerals given to the respective parts in the embodiments described later.

  For example, packages packed in cardboard boxes are stacked on the pallet. As for the load stacked in a plurality of stages, the upper one that is not subjected to a load from the upper part is unstable. If the upper luggage is fixed to each other, the lower luggage will be held down by the load from the top and stabilized, making it difficult for the cargo to collapse. However, using a wide belt band is effective because the entire load is fixed by the belt band.

The bag is wrapped around the load by a belt belt for preventing collapse of the load, and the effective length is adjusted so that each load can be fastened to a certain extent and fixed to each other.
At this time, an appropriate tightening force can be obtained by the stretchable portion in the longitudinal direction of the belt band.

  In addition, the double mesh polypropylene resin net part of the warp weaving that can be stretched in the longitudinal direction has essentially no stretch in the longitudinal direction of the entire belt band, and stretches in the width direction. For example, when the outer shape of the baggage is not a flat surface but an irregular shape, the belt band can be flexibly deformed along the outer shape, and good adhesion and retention can be exhibited. .

  The belt band is made of a net of polyolefin mono-fragment yarn warp weaving (as an example, we can use a Russell weaving with a Russell machine), and can be used to show transparency, ventilation and printability. have. Thereby, it is possible to visually recognize characters and the like displayed on the inner luggage surface where the belt band is attached. In addition, since cold air can pass through the belt body of the belt, the whole can be evenly cooled even when the baggage is rapidly frozen. Furthermore, there is no concern that airflow may be disturbed even if the packaging material has a vent. It can be printed on the belt itself for checking the belt band and advertising / promotion.

  Further, since the belt band is a net-like net body and has ventilation, almost no condensation occurs even when the belt is taken out from a cold place such as a freezer. Even if there is some condensation, it diverges and dries in a very short time.

  At least one end in the longitudinal direction of the belt band is provided with a handle member and means for preventing the width of the band from changing. When the is pulled, the width of the band can be prevented from shrinking.

(A) According to the present invention, the belt band can prevent the collapse of the load on the load carrying pallet, and can exhibit the transparency and ventilation of the load and can prevent the load from collapsing stably. In the belt, the grip part at one end, the hook-and-loop fastener part at both ends of the belt, the net part of the double mesh polyolefin resin warp woven weaving that can be stretched in the longitudinal direction, and the stretching in the longitudinal direction do not occur A part made of a net of a polyolefin resin warp knitting (may be Raschel weaving) and stretched in the longitudinal direction of the belt band when fixed around a bag Thus, an appropriate tightening force can be obtained.
Also, due to the part that does not inherently stretch in the longitudinal direction of the belt band, for example, if the outer shape of the load is not flat but irregular, the band is flexibly deformed along the outer shape. And can exhibit good adhesion and retention.

(B) Since the belt body of the main belt has transparency, it is possible to confirm characters on the surface of the baggage where the belt band is attached. For example, it is necessary to confirm the display contents. There is no need to shift or remove the belt strip to see the hidden part.

(C) Since the belt band has ventilation, cold air can pass through the band, and the whole can be evenly cooled even when the baggage is rapidly frozen. Moreover, even if the packing material has a vent hole, there is no worry of obstructing the ventilation.

(D) Even when the baggage is taken out of a cold place such as a freezer, the belt band hardly causes condensation, and even if it is somewhat condensed, it will diverge and dry in a very short time. And handling by getting wet becomes easy.

(E) A grip member and means for preventing the width of the belt body from changing at least at one end in the longitudinal direction of the belt body have a handle member when the belt belt body is wrapped around a load. Thus, when the end portion is pulled, the width of the band can be prevented from contracting. As a result, the binding means provided on the band is not deformed, and the binding can be easily and reliably performed.

  The present invention will be described in detail based on the embodiments shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of a load collapse prevention belt according to the present invention,
FIG. 2 is an enlarged explanatory view showing the structure of the handle member side.

  The load collapse prevention belt B includes a belt belt made of a net, a hook-and-loop fastener as a fastening means, a handle member, and a width fixing member.

Belt belt 1 is made of a transparent fiber of polyethylene (PE), and is a warp knitted net (warp yarn, weft yarn: 300D: monofilament of about 0.2 mm, mesh: 3 mm) and polypropylene ( It is made of a transparently woven PP (PP) fiber and a warp knitted net (warp yarn, weft yarn: 300D: monofilament of about 0.2 mm, mesh: 2 mm).
The belt band 1 has sufficient strength (such as tensile strength) to prevent collapse of the load.

The belt band 1 is composed of a stretchable band 6 (PP net) having a required length, and the non-stretchable band 7 (PE net) occupies the majority.
The elastic band 6 is double knitted and is thick. The elastic band 6 can be expanded and contracted in the longitudinal direction and does not substantially expand and contract in the width direction.

  Further, the non-stretchable band 7 is single knitted and has a small thickness. The non-stretchable band 7 does not substantially expand and contract in the longitudinal direction and can expand and contract in the width direction.

  The stretchable band 6 and the non-stretchable band 7 are made of the above-described materials, and thus have transparency and ventilation, respectively. That is, the band 1 can visually recognize what is on the back side through it, and can also directly apply cold air or the like to the luggage on the back side through it.

The hook-and-loop fastener 3 is a hook tape type made of nylon, and is set a little longer in order to adjust the effective length when the belt band 1 is wound around a load.

  A grip member 4 made of a flat string is provided at the front end of the non-stretchable band 7 of the belt band 1 by sewing both ends to both ends in the width direction of the non-stretchable band 7. A metal-made, straight rod-like width fixing member 5 is attached to the tip of the non-stretchable band 7 in parallel with the width direction so as to prevent the width from changing (see FIG. 2). The width fixing member 5 is formed to have substantially the same length as the width of the non-stretchable band 7.

  Further, the surface fastener 2 is sewn on the surface of the non-stretchable band 7 opposite to the side where the surface fastener 3 is provided. The hook-and-loop fastener 2 can be attached to and peeled off from the hook-and-loop fastener 3.

  In this embodiment, the width of the belt 1 is 250 mm, the length of the belt 1 is 4300 mm, the length of the stretchable band 6 is 500 mm, and the length of the non-stretchable band 7 is 3150 mm. The length of the hook-and-loop fastener 3 is 500 mm and the length of the hook-and-loop fastener 2 is 150 mm. However, the length of the hook-and-loop fastener 2 is not limited to this, and can be appropriately set according to the shape and size of the luggage. The specific gravity of this belt band was about 0.3.

(Function)
FIG. 3 is an explanatory perspective view showing a state in which a load on a pallet is tightened using a load collapse prevention belt. With reference to FIG. 1 thru | or FIG. 3, the usage method and effect | action of a load collapse prevention belt are demonstrated.

  First, on the pallet P, for example, packages packed in cardboard boxes are stacked. The three-tiered luggage (L1: lower stage, L2: middle stage, L3: upper stage, each set is a set of five) is not loaded with the upper stage luggage L3 that is not loaded from the upper part and the middle stage luggage L2 with a smaller load. Since they are stable, they are fixed to each other by a belt B for preventing collapse of goods. If the upper luggage L3 and the middle luggage L2 are fixed to each other, the lower luggage L1 below the luggage L1 is held down and stabilized by the load from above, and the entire luggage is less likely to collapse.

  The load collapse prevention belt B is wrapped around both the luggage L2 and L3, wrapped around the luggage L2, and the effective length is adjusted so that each luggage L2 and L3 can be fixed to each other by tightening to some extent. The hook-and-loop fastener 2 is fixed to the fastener 3 and the cargo is tightened. At this time, an appropriate tightening force can be obtained by the elastic band 6 having elasticity in the longitudinal direction of the band 1.

  Moreover, since the width fixing member 5 is provided on one end side where the handle member 4 of the band 1 is provided, when the band 1 is wound around a load, when the end is pulled with the handle member 4, The width of the band 1 can be prevented from shrinking. Thereby, the hook-and-loop fastener 2 provided in the belt body 1 is not deformed, and the fixing with the hook-and-loop fastener 3 can be easily and reliably performed.

  Further, in this example, the surface of the luggage is a flat surface. However, for example, when the outer shape of the luggage is not a flat surface but an irregular shape having irregularities, the longitudinal direction of the belt body 1 is essentially non-stretchable. The elastic band 7 can flexibly deform the band 1 so as to follow its outer shape, and therefore can exhibit good adhesion and retention.

  The stretchable band 6 and the non-stretchable band 7 constituting the belt band 1 are made of a warp knitted net (as an example, a Raschel weave), and have a mesh that can exhibit transparency and ventilation. Thereby, it is possible to visually recognize characters and the like displayed on the surface of the luggage where the belt band 1 is covered. In addition, since the cool air can pass through the belt body 1 of the belt, the whole can be evenly cooled even when the baggage is rapidly frozen.

  Furthermore, there is no concern that the ventilation may be disturbed even if the packaging material has a vent (such as vegetables or fruits). Since the band 1 is a net, for example, when the baggage is taken out from a cold place such as a freezer, almost no condensation occurs, and even if some condensation occurs, it will diverge and dry in a very short time. There is no hindrance.

  Note that the terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
