Description

本発明は、荷崩れ防止シート及びこれを用いた包装体に関する。具体的には、段積みされた荷物に巻きつけて使用する荷崩れ防止シートに関する。 The present invention relates to a load collapse prevention sheet and a package using the same. Specifically, the present invention relates to a load collapse prevention sheet that is used by being wrapped around stacked packages.

集積された荷物を運送する際、各荷物はパレットと呼ばれる荷台の上に水平方向及び水平方向に垂直な方向に段積みされる。パレットに段積みされた荷物は、トラック等の運送手段の近くに運ぶため、フォークリフト等でパレットごと移動される。パレットの上で段積みされた荷物は、フォークリフトの急な動きや、運送手段の運送中の不測の動きにより、ずれたり、崩れたりすることがある。 When transporting the accumulated packages, the packages are stacked in a horizontal direction and a direction perpendicular to the horizontal direction on a loading platform called a pallet. Luggage stacked on a pallet is moved together with the pallet by a forklift or the like in order to carry it near a transportation means such as a truck. Baggage stacked on the pallet may be displaced or collapsed due to sudden movement of the forklift or unexpected movement during transportation of the transportation means.

このような荷崩れを防止するため、荷物にラッピングフィルムを巻きつける場合があった。しかしながら、ラッピングフィルムでは、荷崩れを防止する効果を奏する締め付け強度が十分に得られない。このため、荷物が段積みした１８リットル缶（一斗缶）である等、荷物の重量が大きい場合には、荷崩れを十分に防止することができないという問題があった。そこで、荷崩れを確実に防ぐことのできる締め付け強度を有する荷崩れ防止シートが必要とされている。 In order to prevent such collapse of the load, a wrapping film may be wound around the load. However, with a wrapping film, it is not possible to obtain a sufficient fastening strength that has the effect of preventing the collapse of the load. For this reason, there has been a problem that the collapse of the load cannot be prevented sufficiently when the weight of the load is large, such as 18-liter cans (pouch cans) stacked. Therefore, there is a need for a load collapse prevention sheet having a tightening strength that can reliably prevent load collapse.

例えば、帯状のシート部材の長手方向の一端と他端に、短手方向に延びる棒状の部材を配置し、この棒状部材に係止部材を設けて、一端側と他端側から係止部材を係止させることにより荷崩れを防止するシートが知られている（例えば、特許文献１参照）。 For example, a rod-shaped member extending in the short direction is disposed at one end and the other end in the longitudinal direction of the belt-shaped sheet member, and a locking member is provided on the rod-shaped member, and the locking member is provided from one end side and the other end side. There is known a sheet that prevents the collapse of the load by being locked (see, for example, Patent Document 1).

特開２００４−１９６４０４号公報JP 2004-196404 A

特許文献１に記載の荷崩れ防止シートでは、シート部材を引張る力を棒状部材によってシート部材の短手方向に均等に伝えるため、シートが緩むことを防止することができる。しかしながら、特許文献１に記載の荷崩れ防止シートでは、１８リットル缶のような重量のある荷物に巻きつけた場合、荷物がずれるとシート部材が破損する場合がある。特に、荷崩れ防止シートをきつく締めれば締めるほど、棒状部材とシートとの繋ぎ目が、破損する可能性が高まるという問題があった。 In the load collapse prevention sheet described in Patent Document 1, since the force for pulling the sheet member is evenly transmitted in the short direction of the sheet member by the rod-shaped member, the sheet can be prevented from loosening. However, in the load collapse prevention sheet described in Patent Document 1, when wrapped around a heavy load such as an 18-liter can, the sheet member may be damaged if the load is displaced. In particular, the tighter the load collapse prevention sheet, the higher the possibility that the joint between the rod-shaped member and the sheet is damaged.

上記のような問題に鑑み、本発明は、重量の大きい段積みされた荷物の荷崩れを防止する荷崩れ防止シートを提供することを目的とする。 In view of the problems as described above, it is an object of the present invention to provide a load collapse prevention sheet that prevents the load collapse of heavy stacked packages.

図２は、荷崩れ防止シート１の平面図である。図２においてシート部材２は、長手方向の中央部が省略されているが、略長方形の形状を有する。長手方向の長さは、段積みされた荷物１０に巻きつけて固定するのに十分な長さであり、例えば、４４００ミリから４８００ミリの間が好ましく、特に４５００ミリから４７００ミリの間、さらには４６００ミリが好ましい。短手方向の長さは、例えば８００ミリから１０００ミリの間、特に８５０ミリから９５０ミリ、さらには９００ミリが好ましい。シート部材２の短手方向の長さは、段積みされた荷物１０の高さ方向の長さよりも短いことが好ましい。シート部材２の素材は、例えば、厚地のポリエステル又はナイロンである。 FIG. 2 is a plan view of the load collapse prevention sheet 1. In FIG. 2, the sheet member 2 has a substantially rectangular shape although the central portion in the longitudinal direction is omitted. The longitudinal length is sufficient to wrap around and fasten the stacked packages 10, for example, preferably between 4400 mm and 4800 mm, in particular between 4500 mm and 4700 mm, Is preferably 4600 mm. The length in the lateral direction is preferably, for example, between 800 mm and 1000 mm, particularly 850 mm to 950 mm, and more preferably 900 mm. The length in the short direction of the sheet member 2 is preferably shorter than the length in the height direction of the stacked luggage 10. The material of the sheet member 2 is, for example, thick polyester or nylon.

一対の棒状部材４は、それぞれがシート部材２の一端側２１と他端側２２に、シート部材２の短手方向に延びるように設けられている。シート部材２の一端側２１から一方の棒状部材４までの長さと、シート部材２の他端側２２から他方の棒状部材４までの長さとは異なる。シート部材２の他端側２２から他方の棒状部材４までの長さは、シート部材２の一端側２１から一方の棒状部材４までの長さよりも長い。棒状部材４から他端側２２までのシート部材２の一部は、シート部材２を一端と他端が重なるように巻きつける際の、重なり代２７となる。棒状部材４は、例えば、強化プラスチック製であり、寸法は、長さが８８０ミリ、幅が７ミリ、高さが３ミリである。 The pair of rod-like members 4 are provided on one end side 21 and the other end side 22 of the sheet member 2 so as to extend in the lateral direction of the sheet member 2. The length from one end side 21 of the sheet member 2 to one rod-like member 4 is different from the length from the other end side 22 of the sheet member 2 to the other rod-like member 4. The length from the other end side 22 of the sheet member 2 to the other rod-shaped member 4 is longer than the length from the one end side 21 of the sheet member 2 to the one rod-shaped member 4. A part of the sheet member 2 from the rod-shaped member 4 to the other end side 22 becomes an overlap margin 27 when the sheet member 2 is wound so that one end and the other end overlap each other. The rod-shaped member 4 is made of, for example, reinforced plastic, and has dimensions of 880 mm in length, 7 mm in width, and 3 mm in height.

シート部材２の表側には、留め具３がシート部材２の短手方向に互いに間隔を空けて設けられている。なお、便宜上、留め具３が設けられている面を表側といい、反対側を裏側という。留め具３は、棒状部材４のそれぞれの近傍に配置される係止部材３０ａ、３０ｂからなり、シート部材２の一端側２１と他端側２２とに配置された係止部材３０ａ、３０ｂを互いに係止してシート部材２を固定する。（図４参照）。シート部材２の一端側２１の棒状部材４の近傍に設けられる係止部材３０ａは、バックル部３１と、ベルト部３２とを有する。バックル部３１は、例えば、樹脂製もしくは金属製を用いることができるが、強度の点からスチール製が好ましく、さらに防錆の点からステンレス製もしくは、ビニール等で防錆コーティングされたスチール製が好ましい。ベルト部３２は、バックル部３１をシート部材２に接続する。このため、ベルト部３２の一端はシート部材２に固定され、他端は、バックル部３１を挿通して折り返される。シート部材２の他端側２２の棒状部材４の近傍に設けられる係止部材３０ｂは、フック部３４と、フック固定部３３とを備える。フック固定部３３は、ベルト部３２と同じ素材の帯状の部材である。フック固定部３３は、フック部３４に挿通してＵ字状に折り返され、Ｕ字状の両端部がシート部材２に固定される。 On the front side of the sheet member 2, fasteners 3 are provided at intervals in the short direction of the sheet member 2. For convenience, the surface on which the fastener 3 is provided is referred to as the front side, and the opposite side is referred to as the back side. The fastener 3 includes locking members 30 a and 30 b disposed in the vicinity of the rod-shaped member 4, and the locking members 30 a and 30 b disposed on the one end side 21 and the other end side 22 of the sheet member 2 are connected to each other. The sheet member 2 is fixed by locking. (See FIG. 4). The locking member 30 a provided in the vicinity of the rod-like member 4 on the one end side 21 of the sheet member 2 has a buckle portion 31 and a belt portion 32. The buckle portion 31 can be made of, for example, resin or metal, but is preferably made of steel from the viewpoint of strength, and is further preferably made of stainless steel or steel coated with rust prevention with vinyl or the like from the viewpoint of rust prevention. . The belt portion 32 connects the buckle portion 31 to the seat member 2. For this reason, one end of the belt portion 32 is fixed to the sheet member 2, and the other end is folded through the buckle portion 31. The locking member 30 b provided in the vicinity of the rod-like member 4 on the other end side 22 of the sheet member 2 includes a hook portion 34 and a hook fixing portion 33. The hook fixing portion 33 is a band-shaped member made of the same material as the belt portion 32. The hook fixing portion 33 is inserted into the hook portion 34 and folded back into a U shape, and both end portions of the U shape are fixed to the sheet member 2.

シート部材２と、係止部材３０ａのベルト部３２の一端及び係止部材３０ｂのフック固定部３３とが固定される部分とが、固定部５である。ベルト部３２の一端及びフック固定部３３は、シート部材２に縫合されて固定される。 The fixing portion 5 is a portion where the sheet member 2 and one end of the belt portion 32 of the locking member 30a and the hook fixing portion 33 of the locking member 30b are fixed. One end of the belt portion 32 and the hook fixing portion 33 are sewn and fixed to the sheet member 2.

留め具３は、シート部材２の短手方向の両端に一つずつ設けられ、この両端の間に二つの留め具３が間隔を空けて、合計４つ配置されている。留め具３同士の間隔は、均等でない。一例を挙げると、シート部材２の短手方向の端部のうち、使用時に荷物１０の高さ方向の上側に配置される上端部２３から数えた場合、上端部２３に配置される留め具３と、この留め具３の下側に配置される二段目の留め具３との、留め具３の向かい合う端部同士の間の長さは２９０ミリである。二段目の留め具３と、さらに下側の三段目の留め具３との、向かい合う端部同士の長さは、３１０ミリである。三段目の留め具３と最も下側の下端部２４に配置される留め具３との、留め具３の向かい合う端部の間の長さは１４０ミリである。 One fastener 3 is provided at each of both ends of the sheet member 2 in the short direction, and two fasteners 3 are arranged between the both ends with a space therebetween. The intervals between the fasteners 3 are not uniform. As an example, when the sheet member 2 is counted from the upper end 23 that is disposed on the upper side in the height direction of the luggage 10 during use, the fastener 3 disposed on the upper end 23. The length between the opposite ends of the fastener 3 with the second-stage fastener 3 arranged below the fastener 3 is 290 mm. The length of the opposing ends of the second stage fastener 3 and the lower third stage fastener 3 is 310 mm. The length between the opposite ends of the fastener 3 between the third-stage fastener 3 and the fastener 3 disposed at the lowermost lower end 24 is 140 mm.

４つの留め具３のうち少なくとも一つの留め具３と、該一つの留め具３に隣接する他の留め具３との間隔は、段積みされた荷物１０の一個の高さ方向の長さに対応している。すなわち、本実施形態では、荷物１０は１８リットル缶であり、１８リットル缶の高さ方向の寸法は、３４９プラスマイナス２ミリと日本工業規格により規定されている。留め具３のベルト部３２及びフック固定部３３の幅は４０ミリである。このため、上述の配置によれば、上から二段目の留め具３と三段目の留め具３との間の寸法３１０ミリに、留め具３の幅４０ミリを足すと、１８リットル缶の高さ方向の寸法にほぼ対応する。 The distance between at least one of the four fasteners 3 and the other fasteners 3 adjacent to the one fastener 3 is equal to the height of one stacked luggage 10 in the height direction. It corresponds. In other words, in the present embodiment, the luggage 10 is an 18-liter can, and the height dimension of the 18-liter can is defined as 349 plus or minus 2 millimeters according to Japanese Industrial Standards. The width of the belt portion 32 and the hook fixing portion 33 of the fastener 3 is 40 mm. For this reason, according to the above arrangement, when the width of the fastener 3 is added to the dimension 310 mm between the second-stage fastener 3 and the third-stage fastener 3 from the top, the 18-liter can It almost corresponds to the dimension in the height direction.

次に、補強板６について説明する。補強板６は、略長方形の平板の形状を有する。補強板６自体の短手方向の長さは、係止部材３０ａ、３０ｂのベルト部３２及びフック固定部３３の帯状の素材における短手方向の長さよりも長い。また、補強板６自体の長手方向の長さは、少なくとも、互いに間をあけて配置されている棒状部材４と固定部５とをともに覆うことが可能な長さを有する。補強板６は、シート部材２と係止部材３０ａ、３０ｂとが固定される固定部５を補強する。なお、補強板６の形状や構成はこれに限定されない。補強板６は、係止部材３０ａ、３０ｂ毎に設置されている必要はなく、例えば、補強板６の１枚に対して複数の係止部材３０ａ、３０ｂが配置されていてもよい。 Next, the reinforcing plate 6 will be described. The reinforcing plate 6 has a substantially rectangular flat plate shape. The length in the short direction of the reinforcing plate 6 itself is longer than the length in the short direction of the belt-like material of the belt portions 32 and the hook fixing portions 33 of the locking members 30a and 30b. In addition, the length of the reinforcing plate 6 itself in the longitudinal direction has a length that can cover at least both the rod-like member 4 and the fixing portion 5 that are arranged with a space therebetween. The reinforcing plate 6 reinforces the fixing portion 5 to which the sheet member 2 and the locking members 30a and 30b are fixed. The shape and configuration of the reinforcing plate 6 are not limited to this. The reinforcing plate 6 does not need to be installed for each of the locking members 30a and 30b. For example, a plurality of locking members 30a and 30b may be arranged for one reinforcing plate 6.

図３は、荷崩れ防止シート１の断面において部材の配置を説明する説明図である。図３に示すように、シート部材２の一端側２１及び他端側２２はそれぞれ三つ折りに折り返されている。荷崩れ防止シート１は、シート部材２の長手方向の中央部から連続し、一端側２１及び他端側２２からこの中央部に向かって折り返される第１の折返し部２５を有する。第１の折返し部２５は、折り返したシート部材２の内側で互いに向き合う面と面の間の部分である。また、荷崩れ防止シート１は、第１の折返し部２５から連続してシート部材２の長手方向の外側に向かって折り返される第２の折返し部２６を備える。第２の折返し部２６は、第１の折返し部２５から折り返されたシート部材２の内側で互いに向き合う面と面の間の部分である。 FIG. 3 is an explanatory diagram for explaining the arrangement of members in the cross section of the load collapse prevention sheet 1. As shown in FIG. 3, the one end side 21 and the other end side 22 of the sheet member 2 are folded back into three. The load collapse prevention sheet 1 includes a first folded portion 25 that is continuous from the central portion in the longitudinal direction of the sheet member 2 and is folded from the one end side 21 and the other end side 22 toward the central portion. The first folded portion 25 is a portion between the surfaces facing each other inside the folded sheet member 2. In addition, the load collapse prevention sheet 1 includes a second folded portion 26 that is continuously folded from the first folded portion 25 toward the outside in the longitudinal direction of the sheet member 2. The second folded portion 26 is a portion between the surfaces facing each other inside the sheet member 2 folded from the first folded portion 25.

第１の折返し部２５には、補強板６が設けられ、第２の折返し部２６には、棒状部材４が設けられる。図３に示すように、棒状部材４は、断面視において補強板６にシート部材２を介して重なるように設けられている。 The first folded portion 25 is provided with the reinforcing plate 6, and the second folded portion 26 is provided with the rod-like member 4. As shown in FIG. 3, the rod-like member 4 is provided so as to overlap the reinforcing plate 6 via the sheet member 2 in a cross-sectional view.

補強板６と、シート部材２とは、縫合される。したがって、補強板６は、縫合が可能な程度の硬度と、シート部材２を引張る力に対向できる程度の引張強度を備える。補強板６は、発泡ポリエチレン等で構成されることが好ましい。図３における点線は縫合部分を示す。補強板６と、シート部材２とは、棒状部材４の短手方向の両端の近傍で縫合される。したがって、第１の折返し部２５と、補強板６と、第２の折返し部２６とは、棒状部材４の短手方向の両端においてともに固定される。これにより棒状部材４は、第２の折り返し部２６の内部に設けられる。 The reinforcing plate 6 and the sheet member 2 are stitched together. Therefore, the reinforcing plate 6 has a hardness that allows stitching and a tensile strength that can be opposed to a force that pulls the sheet member 2. The reinforcing plate 6 is preferably made of foamed polyethylene or the like. A dotted line in FIG. 3 indicates a stitched portion. The reinforcing plate 6 and the sheet member 2 are stitched in the vicinity of both ends of the rod-like member 4 in the short direction. Therefore, the first folded portion 25, the reinforcing plate 6, and the second folded portion 26 are fixed together at both ends of the rod-like member 4 in the short direction. Thereby, the rod-like member 4 is provided inside the second folded portion 26.

図４は、図１に示す留め具３の拡大図である。図３及び図４に示すように、補強板６は、係止部材３０ａ、３０ｂと、シート部材２とに縫合により固定されている。具体的には、係止部材３０ａのベルト部３２及び係止部材３０ｂのフック固定部３３とが、シート部材２を介して補強板６に接続されている。補強板６は、棒状部材４の短手方向の一端から他端と、固定部５の全体とを裏打ちするように配置され、それぞれの縫合部分を補強する。 FIG. 4 is an enlarged view of the fastener 3 shown in FIG. As shown in FIGS. 3 and 4, the reinforcing plate 6 is fixed to the locking members 30 a and 30 b and the sheet member 2 by sewing. Specifically, the belt portion 32 of the locking member 30 a and the hook fixing portion 33 of the locking member 30 b are connected to the reinforcing plate 6 via the sheet member 2. The reinforcing plate 6 is disposed so as to line one end to the other end of the rod-like member 4 in the lateral direction and the entire fixing portion 5, and reinforces each stitched portion.

ベルト部３２をバックル部３１に挿通して折り返したバックル部３１付近の根元部分３２ａには、ベルト部３２に脱着可能な緩み止め８が設けられている。緩み止め８は、例えば一面が雌部材でその反対面が雄部材の両面の面ファスナを２枚用いて作成される。２枚の両面の面ファスナは、表裏が互い違いになるように隣り合わされ、隣接する端部を縫合される。具体的には、１枚の面ファスナの雌部材側を表とした場合に、隣接する２枚目の面ファスナは、雄部材側が表側となるように繋ぎ合わされる。 A looseness stop 8 that can be attached to and detached from the belt portion 32 is provided at a root portion 32a in the vicinity of the buckle portion 31 that is returned by inserting the belt portion 32 through the buckle portion 31. The looseness stopper 8 is formed by using, for example, two surface fasteners, one surface of which is a female member and the opposite surface of which is a male member. The two surface fasteners are placed next to each other so that the front and back sides are staggered, and the adjacent ends are sewn together. Specifically, when the female member side of one surface fastener is set as the front, the adjacent second surface fasteners are joined so that the male member side is the front side.

繋ぎ合わされて一本の帯状となった緩み止め８は、最初に雌部材側をベルト部３２に当接するように巻きつけられる。雌部材側は、ベルト部３２に係着しないため、緩み止め８は自由にベルト部３２を滑って移動することができる。さらに巻き続けると、雌部材側に雄部材側を巻きつけるようになる。雄部材は雌部材に係着するため、緩み止め８をバックル部３１付近の根元部分３２ａ側に移動させた後、緩み止め８をきつく巻いて雄部材側の面を雌部材側に合わせることにより、緩み止め８がベルト部３２に固定される。 The looseness stoppers 8 that are joined together to form a single band are wound so that the female member side first comes into contact with the belt portion 32. Since the female member side is not engaged with the belt portion 32, the locking member 8 can freely slide on the belt portion 32 and move. If the winding continues further, the male member side is wound around the female member side. Since the male member is engaged with the female member, the locking member 8 is moved to the base portion 32a side near the buckle portion 31, and then the locking member 8 is tightly wound so that the surface on the male member side is aligned with the female member side. The looseness stopper 8 is fixed to the belt portion 32.

ベルト部３２のバックル部３１付近の根元部分３２ａは、ベルト部３２の長手方向に沿う側縁同士を合わせるように二つに折られる。緩み止め８は、ベルト部３２の折られた部分に巻きつけて装着される。巻きつけられる部分が細く二つに折られ、そうでない部分が広がることで、緩み止め８が下方に下がらなくなるため、バックル部３１の緩みが防止できる。 The base portion 32 a in the vicinity of the buckle portion 31 of the belt portion 32 is folded in two so that the side edges along the longitudinal direction of the belt portion 32 are aligned. The looseness stopper 8 is attached by being wound around a folded portion of the belt portion 32. Since the part to be wound is thinly folded in two and the part that is not spread is widened, the loosening stopper 8 does not fall downward, so that the buckle part 31 can be prevented from loosening.

図５は、荷崩れ防止シート１を段積みされた荷物１０に巻きつけて固定する工程を説明するための説明図である。図５を参照して、荷崩れ防止シート１の使用方法を説明するとともに、荷崩れ防止シート１を巻きつけて積荷の荷崩れを防止する荷崩れ防止方法を説明する。積荷１００は、段積みされた荷物１０と、段積みされた荷物１０に巻きつけた荷崩れ防止シート１と、により構成される。 FIG. 5 is an explanatory diagram for explaining a process of winding and fixing the load collapse prevention sheet 1 around the stacked luggage 10. With reference to FIG. 5, while explaining the usage method of the load collapse prevention sheet 1, the load collapse prevention method which winds the load collapse prevention sheet 1 and prevents the load collapse of a load is demonstrated. The load 100 includes a stacked package 10 and a load collapse prevention sheet 1 wound around the stacked package 10.

まず、荷台１１の上に段積みされた荷物１０の一端に、引っ掛け部材７を挟み込み、これを端緒として荷崩れ防止シート１を反時計回りに巻きつける。このとき、三つ折りにされたシート部材２の内部に配置されている補強板６のうち、少なくとも一つの補強板６と、シート部材２の短手方向においてこの補強板６に隣接する他の補強板６とが、段積みされた荷物１０の高さ方向において、隣接する荷物１０同士の隙間に配置されるようにシート部材２を巻きつける。また、このとき、段積みされた荷物１０の最も下方の荷物１０の一部が見えるように、段積みされた荷物１０にシート部材２を巻きつける。 First, the hook member 7 is sandwiched between one end of the load 10 stacked on the loading platform 11, and the load collapse prevention sheet 1 is wound counterclockwise using this as a starting point. At this time, at least one reinforcing plate 6 among the reinforcing plates 6 disposed inside the sheet member 2 folded in three and other reinforcing members adjacent to the reinforcing plate 6 in the short direction of the sheet member 2. The sheet member 2 is wound so that the plate 6 is disposed in the gap between the adjacent loads 10 in the height direction of the stacked loads 10. At this time, the sheet member 2 is wound around the stacked packages 10 so that a part of the lowest package 10 can be seen.

図５に示されるように、シート部材２の他端側２２から係止部材３０ｂまでは一定の幅があり、重なり代２７となっている。シート部材２を反時計回りに巻くと、この重なり代２７の上にシート部材２の一端側２１が重なり、係止部材３０ａが係止部材３０ｂに近づく。そして、シート部材２の一端側２１を強く引っ張り、係止部材３０ａのバックル部３１と係止部材３０ｂのフック部３４とを係止する。係止した後、ベルト部３２をフック部３４の反対側に向かって引き締める。きつく引き締めたところで、ベルト部３２をバックル部３１に挿通して折り返したバックル部３１付近の根元部分３２ａにおいて、ベルト部３２の長手方向に沿う側縁同士を合わせるように二つに折り曲げ、緩み止め８を根元部分３２ａへ移動させる。４つの係止部材３０ａ、３０ｂをすべて同様に引き締めて係止することにより、荷崩れ防止シート１が荷物１０に装着される。 As shown in FIG. 5, there is a certain width from the other end side 22 of the sheet member 2 to the locking member 30 b, which is an overlap margin 27. When the sheet member 2 is wound counterclockwise, the one end side 21 of the sheet member 2 overlaps the overlap allowance 27, and the locking member 30a approaches the locking member 30b. And the one end side 21 of the sheet | seat member 2 is pulled strongly, and the buckle part 31 of the latching member 30a and the hook part 34 of the latching member 30b are latched. After locking, the belt portion 32 is tightened toward the opposite side of the hook portion 34. When tightly tightened, the base portion 32a in the vicinity of the buckle 31 where the belt 32 is inserted through the buckle 31 and folded back is folded in two so that the side edges along the longitudinal direction of the belt 32 are aligned with each other. 8 is moved to the root portion 32a. By tightening and locking all four locking members 30 a and 30 b in the same manner, the load collapse prevention sheet 1 is mounted on the load 10.

本実施形態によれば、棒状部材４がシート部材２の短手方向に延びるように配置されているので、係止部材３０ａ、３０ｂが互いに近づくように、シート部材２が引張られた場合、引張る力が棒状部材４を通してシート部材２に均等に伝わる。このため、シート部材２をより強く引き締めることが可能になる。 According to the present embodiment, since the rod-like member 4 is arranged so as to extend in the short direction of the sheet member 2, when the sheet member 2 is pulled so that the locking members 30a and 30b approach each other, the rod-like member 4 is pulled. The force is evenly transmitted to the sheet member 2 through the rod-shaped member 4. For this reason, the sheet member 2 can be tightened more strongly.

留め具３は、シート部材２の短手方向に間隔を空けて４つ設けられている。このため、段積みされた荷物１０の高さ方向に対して４箇所引き締める力を強くかけることができる。したがって、１８リットル缶のような一つの重量が重い荷物１０であっても、荷崩れを効果的に防止することができる。 Four fasteners 3 are provided at intervals in the short direction of the sheet member 2. For this reason, the force which tightens four places with respect to the height direction of the packaged goods 10 can be applied strongly. Therefore, even if it is the heavy load 10 like a 18 liter can, collapse of a load can be prevented effectively.

補強板６は、複数の留め具３の位置に対応して、シート部材２を介して棒状部材４及び係止部材３０ａ、３０ｂに接合されている。このため、係止部材３０ａ、３０ｂを互いに近づく方向に強く引き締めたときに、係止部材３０ａ、３０ｂを引き締める力は、固定部５から補強板６を通して棒状部材４に伝えられる。また、補強板６が設けられているために、シート部材２と棒状部材４の繋ぎ目の破損を防ぎ、また、シート部材２に固定されていた係止部材３０ａ、３０ｂの固定部５が、繰り返しの使用により傷んだり、係止部材３０ａ、３０ｂとシート部材２とのつなぎ目で裂けることが防止され、耐久性が向上する。 The reinforcing plate 6 is joined to the rod-shaped member 4 and the locking members 30a and 30b via the sheet member 2 corresponding to the positions of the plurality of fasteners 3. For this reason, when the locking members 30 a and 30 b are strongly tightened in the direction approaching each other, the force for tightening the locking members 30 a and 30 b is transmitted from the fixed portion 5 to the rod-shaped member 4 through the reinforcing plate 6. Further, since the reinforcing plate 6 is provided, the joint between the sheet member 2 and the rod-shaped member 4 is prevented from being damaged, and the fixing portions 5 of the locking members 30a and 30b fixed to the sheet member 2 are Damage due to repeated use or tearing at the joint between the locking members 30a, 30b and the sheet member 2 is prevented, and durability is improved.

補強板６は、シート部材２と縫合可能な程度の硬さの部材で構成されており、シート部材２と縫合されている。縫合することにより糸が補強板６とシート部材とを貫通して接続するため、強い力で引張り、繰り返し使用しても、破損しにくくなる。 The reinforcing plate 6 is composed of a member having a hardness that can be sewn to the sheet member 2, and is sewn to the sheet member 2. Since the thread penetrates and connects the reinforcing plate 6 and the sheet member by stitching, the thread is hardly damaged even if it is pulled with a strong force and repeatedly used.

シート部材２の一端側２１及び他端側２２は、それぞれ三つ折りに折り返され、第１の折返し部２５及び第２の折返し部２６を備えている。シート部材２は、シート部材２の一端側２１及び他端側２２を近づけるように引張られるため、一端側２１及び他端側２２に引張る力が最も大きくかかる。この一端側２１及び他端側２２が三つ折りにされているため、耐久性が向上するとともに、この一端側２１及び他端側２２をより強い力で引張ることができるため、荷崩れを効果的に防止することができる。なお、補強のため、三つ折り以上折り返してもよい。 One end side 21 and the other end side 22 of the sheet member 2 are each folded back into three, and are provided with a first folded portion 25 and a second folded portion 26. Since the sheet member 2 is pulled so that the one end side 21 and the other end side 22 of the sheet member 2 are brought closer to each other, the force that pulls the one end side 21 and the other end side 22 is the largest. Since the one end side 21 and the other end side 22 are folded in three, the durability is improved and the one end side 21 and the other end side 22 can be pulled with a stronger force, so that the load collapse is effective. Can be prevented. In addition, you may fold back more than three for reinforcement.

また、第１の折返し部２５には補強板６が配置され、第２の折返し部２６には、棒状部材４が、断面視で補強板６に重なる位置に配置されている。そして、第１の折返し部２５と、補強板６と、第２の折返し部２６とが、棒状部材４の短手方向の両端においてともに固定され、棒状部材４が第２の折り返し部２６の内部に設けられている。係止部材３０ａ、３０ｂを強く引張ると、係止部材３０ａ、３０ｂと縫合されている部分とそうでない部分とにかかる力の強さが異なるため、係止部材３０ａ、３０ｂと縫合されている部分が弱くなり、裂けやすくなる。しかしながら、係止部材３０ａ、３０ｂは第１の折返し部２５内の補強板６によって固定されているため、シート部材２と係止部材３０ａ、３０ｂと縫合されている部分の耐久性が向上する。
さらに、第１の折返し部２５及び第２の折返し部２６にそれぞれ補強板６及び棒状部材４が断面視で重なるように配置されて固定されているため、シート部材２を強く引張った際に、引き締める力をシート部材２と補強板６と棒状部材４とに一体的に伝えることができる。 Further, the reinforcing plate 6 is disposed in the first folded portion 25, and the rod-like member 4 is disposed in the second folded portion 26 at a position overlapping the reinforcing plate 6 in a sectional view. The first folded portion 25, the reinforcing plate 6, and the second folded portion 26 are fixed together at both ends in the short direction of the rod-shaped member 4, and the rod-shaped member 4 is inside the second folded portion 26. Is provided. When the locking members 30a and 30b are pulled strongly, the strength of the force applied to the portions where the locking members 30a and 30b are sewn and the portions which are not sewn is different. Becomes weaker and easier to tear. However, since the locking members 30a and 30b are fixed by the reinforcing plate 6 in the first folded portion 25, the durability of the portion where the sheet member 2 and the locking members 30a and 30b are sewn is improved.
Furthermore, since the reinforcing plate 6 and the rod-shaped member 4 are arranged and fixed so as to overlap with each other in the sectional view in the first folded part 25 and the second folded part 26, respectively, when the sheet member 2 is pulled strongly, The tightening force can be transmitted integrally to the sheet member 2, the reinforcing plate 6, and the rod-shaped member 4.

本実施形態によれば、補強板６自体の短手方向の長さは、係止部材３０ａ、３０ｂのベルト部３２やフック固定部３３の短手方向の長さよりも長い。このため、複数の補強板６のうち、例えば上から二段目の補強板６と、この補強板６の下側に隣接する補強板６とを、段積みされた荷物１０の上から一段目と二段目の境目と、二段目と三段目との境目に当たるようにシート部材２を巻きつけることができる。段積みされた荷物１０は、高さ方向に積み上げられた境目でずれることが最も多い。このため、荷物１０と荷物１０との境目に、所定の幅を有する補強板６が当接されることにより、効果的に荷崩れが防止される。 According to the present embodiment, the length in the short direction of the reinforcing plate 6 itself is longer than the length in the short direction of the belt portions 32 and the hook fixing portions 33 of the locking members 30a and 30b. For this reason, among the plurality of reinforcing plates 6, for example, the second-stage reinforcing plate 6 from the top and the reinforcing plate 6 adjacent to the lower side of the reinforcing plate 6 are arranged in the first step from the top of the stacked luggage 10. The sheet member 2 can be wound so as to hit the boundary between the second stage and the boundary between the second stage and the third stage. The stacked cargoes 10 are most often displaced at the borders stacked in the height direction. For this reason, when the reinforcing plate 6 having a predetermined width is brought into contact with the boundary between the load 10 and the load 10, the collapse of the load is effectively prevented.

また、本実施形態によれば、シート部材２の短手方向の長さは、段積みされた荷物１０の高さ方向の長さよりも短い。例えば、シート部材２の短手方向の長さは９００ミリであり、１８リットル缶を３段積んだ高さ方向の長さは１０４１ミリ〜１０５３ミリである。このような寸法によれば、３段積みの１８リットル缶に荷崩れ防止シート１を巻きつけた場合、シート部材２の短手方向の寸法が、１８リットル缶の３段分の高さ方向の寸法に満たないため、１８リットル缶の一部が見えることになる。このため、１８リットル缶に付された表示１２等から荷物の内容を知ることができる。
また、３段積みの荷物１０の荷崩れを防止するために、荷物１０の高さ方向のすべてを被覆しなくとも、上記の寸法で十分に荷崩れが防止できるため、製造コストを低減することができる。 Further, according to the present embodiment, the length of the sheet member 2 in the short direction is shorter than the length of the stacked luggage 10 in the height direction. For example, the length of the sheet member 2 in the short direction is 900 mm, and the length in the height direction in which three 18-liter cans are stacked is 1041 mm to 1053 mm. According to such dimensions, when the load collapse prevention sheet 1 is wound around a three-tiered 18 liter can, the short dimension of the sheet member 2 is the height of three tiers of the 18 liter can. Since it is less than the size, a portion of the 18 liter can can be seen. For this reason, the contents of the package can be known from the display 12 or the like attached to the 18 liter can.
In addition, in order to prevent the collapse of the load of the three-tiered load 10, it is possible to sufficiently prevent the collapse of the load with the above dimensions without covering all the heights of the load 10, thereby reducing the manufacturing cost. Can do.

以上のように荷崩れ防止シート１を段積みされた荷物１０に巻きつけることにより、積荷１００の荷崩れが防止できる。 By wrapping the load collapse prevention sheet 1 around the stacked packages 10 as described above, the collapse of the load 100 can be prevented.

本発明の実施形態は、上記の実施形態に何ら限定されることなく、本発明の技術的範囲は、これに限定されるものではない。 The embodiment of the present invention is not limited to the above embodiment, and the technical scope of the present invention is not limited to this.

例えば、補強板６の形状は、長方形に限定されない。補強板６の、シート部材２の短手方向に沿う側の寸法は、ベルト部３２及びフック固定部３３の帯状の素材における短手方向の長さよりも長ければよく、補強板６の、シート部材２の長手方向に沿う側の寸法は、互いに間をあけて配置されている棒状部材４と固定部５とをともに覆うことが可能な長さであればよい。したがって、これらの寸法を有する限り、補強板６の形状は、楕円や多角形等でもよい。また、補強板６の形状が長方形の場合、補強板６の長手方向がシート部材２の短手方向に沿って配置され、補強板６の短手方向がシート部材２の長手方向に沿って配置されていてもよい。 For example, the shape of the reinforcing plate 6 is not limited to a rectangle. The dimension of the reinforcing plate 6 on the side along the short direction of the sheet member 2 may be longer than the length in the short direction of the belt-shaped material of the belt portion 32 and the hook fixing portion 33. The dimension along the longitudinal direction of 2 only needs to be a length that can cover both the rod-like member 4 and the fixed portion 5 that are arranged with a gap therebetween. Therefore, as long as it has these dimensions, the shape of the reinforcing plate 6 may be an ellipse or a polygon. When the shape of the reinforcing plate 6 is rectangular, the longitudinal direction of the reinforcing plate 6 is arranged along the short direction of the sheet member 2, and the short direction of the reinforcing plate 6 is arranged along the longitudinal direction of the sheet member 2. May be.

このような構成によっても、荷崩れ防止シート１を段積みされた荷物１０に巻きつける際に、補強板６を段積みされた荷物１０の高さ方向の境目に当接させることができ、効果的に荷崩れが防止される。 Even with such a configuration, when the load collapse prevention sheet 1 is wound around the stacked luggage 10, the reinforcing plate 6 can be brought into contact with the boundary in the height direction of the stacked luggage 10, which is effective. The cargo collapse is prevented.

さらに、補強板６は、係止部材３０ａ、３０ｂの一つ一つに対応して設けられていなくともよい。一枚の補強板６に複数の係止部材３０ａ又は３０ｂが、シート部材２を介して接合されている形態も、本発明の範囲内である。さらに、シート部材２の一端側２１又は他端側２２において、一枚の補強板と、一方の側に配置されるすべての係止部材３０ａ又は３０ｂとが、シート部材２を介して接合されていてもよい。 Further, the reinforcing plate 6 may not be provided corresponding to each of the locking members 30a and 30b. A form in which a plurality of locking members 30a or 30b are joined to the single reinforcing plate 6 via the sheet member 2 is also within the scope of the present invention. Further, at one end 21 or the other end 22 of the sheet member 2, one reinforcing plate and all the locking members 30 a or 30 b arranged on one side are joined via the sheet member 2. May be.

また、例えば、荷物１０は１８リットル缶ではなく、ほぼ同形状のバッグインボックスでもよい。また、いわゆる８キロ缶でもよい。８キロ缶は、厚さ方向が１８３．５ミリ、幅方向が１８３．５ミリ、高さ方向が３０１．５ミリの缶である。この８キロ缶が、荷台１１に水平方向において幅方向に５個、奥行き方向に５個、水平方向に垂直な高さ方向に３個、合計７５個が載せられている。この場合でも、上述した通り、段積みされた荷物１０の高さ方向における荷物１０と荷物１０との間に補強板６が当接されるように引き締めると、荷崩れが効果的に防止される。 Further, for example, the luggage 10 may be a bag-in-box having substantially the same shape instead of an 18-liter can. Also, a so-called 8-kg can may be used. The 8-kg can is 183.5 mm in the thickness direction, 183.5 mm in the width direction, and 301.5 mm in the height direction. A total of 75 8 kg cans are placed on the loading platform 11 in the horizontal direction in the width direction, 5 in the width direction, 5 in the depth direction, and 3 in the height direction perpendicular to the horizontal direction. Even in this case, as described above, when the reinforcing plate 6 is tightened so that the load 10 is in contact with the load 10 in the height direction of the stacked loads 10, the collapse of the load is effectively prevented. .

なお、シート部材２の短手方向の長さが上記と同様に９００ミリの荷崩れ防止シート１を用いた場合、３段に積まれた８キロ缶は、高さ方向のすべてがシート部材２によって覆われる。しかしながら、荷崩れ防止シート１は荷物１０とともに物流の流通経路で循環するので、１８リットル缶にも８キロ缶にも用いることができ、荷崩れ防止シート１の汎用性が高まる。 When the sheet collapse prevention sheet 1 having a length in the short direction of the sheet member 2 of 900 mm is used as described above, the 8 kg cans stacked in three stages are all in the height direction. Covered by. However, since the load collapse prevention sheet 1 circulates along the distribution route along with the cargo 10, it can be used for both 18 liter cans and 8 kilo cans, and the versatility of the load collapse prevention sheet 1 is enhanced.

次に、本発明の第２実施形態について説明する。第２実施形態の説明において特に説明をしない点については、第１実施形態の説明が適宜援用される。図６は第２実施形態の荷崩れ防止シート１の部分拡大斜視図である。図７は第２実施形態に係る荷崩れ防止シート１の部分拡大断面図である。バックル部３１と緩み止め８は省略してある。第２実施形態では、ベルト部３２に把持部９が設けられている点が、第１実施形態と異なる。 Next, a second embodiment of the present invention will be described. The description of the first embodiment is used as appropriate for points that are not particularly described in the description of the second embodiment. FIG. 6 is a partially enlarged perspective view of the load collapse prevention sheet 1 of the second embodiment. FIG. 7 is a partially enlarged cross-sectional view of the load collapse prevention sheet 1 according to the second embodiment. The buckle portion 31 and the locking stopper 8 are omitted. The second embodiment is different from the first embodiment in that the grip portion 9 is provided on the belt portion 32.

ベルト部３２は、シート部材２の一端側２１に取り付けられる基端部３２１と、基端部３２１の反対側の末端部３２２とを有する。末端部３２２側には、ベルト部３２を引き締める際に把持可能な把持部９が設けられる。 The belt portion 32 includes a base end portion 321 attached to the one end side 21 of the sheet member 2 and a terminal end portion 322 opposite to the base end portion 321. A grip portion 9 that can be gripped when the belt portion 32 is tightened is provided on the end portion 322 side.

図６に示すように、把持部９は略環状である。略環状とは、把持部９の終端が閉じた輪状に形成されている形状をいい、円形に限られない。把持部９は、ベルト部３２の末端部３２２側を折り曲げて末端部３２２をベルト部３２の一部に重ね合わせ、末端部３２２をベルト部３２の一部と接合することにより略環状に形成される。 As shown in FIG. 6, the grip portion 9 is substantially annular. The term “substantially annular” refers to a shape formed in a ring shape in which the terminal end of the grip portion 9 is closed, and is not limited to a circle. The grip portion 9 is formed in a substantially annular shape by bending the end portion 322 side of the belt portion 32, overlapping the end portion 322 with a part of the belt portion 32, and joining the end portion 322 with a portion of the belt portion 32. The

図７に示すように、把持部９の少なくとも一部は、把持された状態で弾性変形可能な部材により構成される。把持部９のうち、ベルト部３２の遠端側には、弾性部材９０が設けられる。具体的には、把持部９のうち、ベルト部３２の遠端側に、ベルト部３２と同一の帯状の部材９１が重ね合わされる。帯状の部材９１とベルト部３２の長手方向に沿う両側縁とは、接合される。これにより、把持部９のうちベルト部３２の遠端側の一部と帯状の部材９１とが合わされた内側は、中空に形成される。この中空の部分に、繊維や樹脂等の弾性部材９０が詰められ、帯状の部材９１の短手方向の端部は、ベルト部３２と接合される。 As shown in FIG. 7, at least a part of the grip portion 9 is formed of a member that can be elastically deformed while being gripped. An elastic member 90 is provided on the far end side of the belt portion 32 in the grip portion 9. Specifically, in the grip portion 9, the same belt-like member 91 as the belt portion 32 is superimposed on the far end side of the belt portion 32. The band-shaped member 91 and both side edges along the longitudinal direction of the belt portion 32 are joined. Thereby, the inner side where the part of the far end side of the belt part 32 and the strip | belt-shaped member 91 are match | combined among the holding parts 9 is formed hollow. The hollow portion is filled with an elastic member 90 such as fiber or resin, and the end portion in the short direction of the band-shaped member 91 is joined to the belt portion 32.

なお、本実施形態では、末端部３２２をベルト部３２に接合した接合箇所の把持部９側から、把持部９の遠端側における帯状の部材９１の長手方向の端部までの長さＬがそれぞれ１００ミリ、把持部９の遠端側に設けられる帯状の部材９１の長手方向の長さが２００ミリを例示できる。また、シート部材２の一端側２１から末端部３２２をベルト部３２に接合した接合箇所の略中心までの長さは４００ミリを例示できる。また、シート部材２はナイロン製を用いることができ、バックル部３１は、樹脂製もしくは金属製を用いることができるが、強度の点からスチール製が好ましく、さらに防錆の点からステンレス製もしくは、ビニール等で防錆コーティングされたスチール製が好ましい。 In the present embodiment, the length L from the grip portion 9 side of the joining portion where the end portion 322 is joined to the belt portion 32 to the longitudinal end portion of the strip-shaped member 91 on the far end side of the grip portion 9 is For example, the length in the longitudinal direction of the strip-shaped member 91 provided on the far end side of the grip portion 9 may be 200 mm. Moreover, the length from the one end side 21 of the sheet member 2 to the approximate center of the joining portion where the end portion 322 is joined to the belt portion 32 can be exemplified as 400 mm. Further, the sheet member 2 can be made of nylon, and the buckle portion 31 can be made of resin or metal, but is preferably made of steel from the viewpoint of strength, and further made of stainless steel from the point of rust prevention, Steel made of rust-proof coating with vinyl or the like is preferable.

第２実施形態によれば、ベルト部３２の末端部３２２側に把持部９を設けた。このため、作業者がシート部材２を荷物１０に巻きつけて引き締める際に、ベルト部３２を手に巻きつけることなく把持部９を把持して引き締めることができる。よって、荷物１０を締め付ける強度が増加し、段積みされた荷物１０の荷崩れを効果的に防止することができる。 According to the second embodiment, the grip portion 9 is provided on the end portion 322 side of the belt portion 32. For this reason, when the operator wraps and tightens the sheet member 2 around the luggage 10, the grip portion 9 can be gripped and tightened without winding the belt portion 32 around the hand. Therefore, the strength for tightening the luggage 10 increases, and the collapse of the stacked luggage 10 can be effectively prevented.

また、把持部９を略環状に構成した。このため把持部９を容易に握ることができ、作業者は、把持部９に力をかけやすくなる。さらに、把持部９の少なくとも一部は、把持された状態で弾性変形可能な部材により構成した。このため、作業者が把持部９を握る際、把持部９が手に食い込むことが防止される。また、把持部９に弾性変形可能な部材が設けられることにより、ベルト部３２のみを略環状に構成する場合と比べて、把持部９がより厚く形成される。作業者は、この厚い部分を握ることができる。把持部９が握りやすいため、作業者は把持部９に力をかけやすい。よって、荷物１０を締め付ける強度が増加し、段積みされた荷物１０の荷崩れを効果的に防止することができる。 Moreover, the holding part 9 was comprised in the substantially cyclic | annular form. For this reason, the grip part 9 can be easily gripped, and the operator can easily apply force to the grip part 9. Furthermore, at least a part of the grip portion 9 is formed of a member that can be elastically deformed while being gripped. For this reason, when an operator grips the grip part 9, it is prevented that the grip part 9 bites into a hand. In addition, by providing a member that can be elastically deformed to the grip portion 9, the grip portion 9 is formed to be thicker than when only the belt portion 32 is configured in a substantially annular shape. The operator can grasp this thick part. Since the grip 9 is easy to grip, the operator can easily apply force to the grip 9. Therefore, the strength for tightening the luggage 10 increases, and the collapse of the stacked luggage 10 can be effectively prevented.

なお、本発明の実施形態は、上記の実施形態に何ら限定されることなく、本発明の技術的範囲は、これに限定されるものではない。例えば、把持部９はベルト部３２の末端部３２２を折り返して形成されているが、ベルト部３２とは別体の部材を末端部３２２に接合して形成してもよい。 In addition, embodiment of this invention is not limited to said embodiment at all, and the technical scope of this invention is not limited to this. For example, the grip portion 9 is formed by folding the end portion 322 of the belt portion 32, but may be formed by joining a member separate from the belt portion 32 to the end portion 322.
