Description

  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.

  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.

  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.

  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).

The material of the sheet member 2 is, for example, thick polyester or nylon.

  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.

  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 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.

  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.

  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 This corresponds approximately to the height dimension of.

  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.

  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.

  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.

  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.

  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.

  A looseness stopper 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 turned back 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.

  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.

  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.

  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.

  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.

  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 to prevent loosening 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.

  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.

  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.

  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.

  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.

  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.

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.

  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.

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.

  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.

  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.

  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.

  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.

  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.

  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. .

  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.

  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.

  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.

  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

  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.

  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.

  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.

  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.

  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.
