Description

[Technical Field]

[0001] The present invention relates to an auxiliary tool for assisting in the task of hanging a hoisting belt of a container bag on a hoisting device. [Background technology]

[0002] Conventionally, flexible container bags known as "flexible container bags" have been known. When lifting and transporting this type of container bag, a worker must first attach the container bag's lifting belt to the forks of a forklift.

[0003] If the worker is also the forklift driver, i.e., if the worker is transporting the container bag by himself, the worker will stop the forklift in a position where it is easy to fasten the lifting belts to the forks, dismount from the forklift, fasten the lifting belts to the forks, then re-mount the forklift and operate the forklift so that the lifting belts are positioned closer to the base of the forks.

[0004] However, if the lifting belts cannot be positioned in the designated positions on the forks so that the container bag can be transported in one go, the worker must dismount from the forklift again to reattach the lifting belts, which requires the worker to repeatedly get on and off the forklift, which not only increases the burden on the worker but also takes time to transport the container bag.

[0005] In view of such problems, Patent Document 1 describes an auxiliary tool that assists in the transport of container bags. This auxiliary tool is installed on the container bag and fixes the lifting belts above the upper surface of the container bag, thereby forming a space below the lifting belts for lifting the lifting belts with a lifting device. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2018-154368 Summary of the Invention [Problem to be solved by the invention]

[0007] However, because the auxiliary device in Patent Document 1 is lifted together with the lifting belt, it is difficult to remove it from the container bag while the container bag is lifted. Therefore, each auxiliary device in Patent Document 1 must be attached to each container bag at all times, and the same number of auxiliary devices as the number of container bags is required, which poses a cost issue.

[0008] Therefore, the present invention provides an auxiliary tool that can simplify the work of transporting container bags while keeping costs down. [Means for solving the problem]

[0009] An auxiliary tool according to one aspect of the present invention is an auxiliary tool that is placed on top of a flexible container bag and assists in the task of hanging a plurality of lifting belts of the container bag on a lifting device, and includes a pair of side bodies that are spaced apart in a first width direction that intersects the up-down direction, each extending in a second width direction that intersects the up-down direction and the first width direction, and that form an arrangement space between them in which the lifting device can be arranged, and a base body that connects the pair of side bodies and defines the bottom of the arrangement space, and is arranged in contact with an upper part of the container bag, and each of the pair of side bodies is exposed upward and extends in the second width direction to hang one of the plurality of lifting belts. The support member has a first lower support surface capable of supporting a first suspension belt from below, a second lower support surface that is juxtaposed to the first lower support surface in the second width direction, is exposed upward, and extends in the second width direction to support a second suspension belt of the plurality of suspension belts from below, a first outer support surface that extends upward from an end of the first lower support surface opposite the second lower support surface, faces inward in the second width direction, and is capable of supporting the first suspension belt from the outside in the second width direction, and a second outer support surface that extends upward from an end of the second lower support surface opposite the first lower support surface, faces inward in the second width direction, and is capable of supporting the second suspension belt from the outside in the second width direction.

[0010] In the above-mentioned assisting tool, the base body may have a distance adjustment mechanism that can change the distance in the first width direction between the pair of side bodies.

[0011] In the above-mentioned auxiliary device, each of the pair of side bodies may have a height adjustment mechanism that can change the vertical position of the connection portion between the first lower support surface and the first outer support surface, and the vertical position of the connection portion between the second lower support surface and the second outer support surface.

[0012] In the above-described assisting tool, the first outer support surface and the second outer support surface may be inclined outward in the second width direction as they extend upward.

[0013] In the above-mentioned auxiliary device, at least one of the pair of side bodies and the base body may be flexible, and the upper ends of the pair of side bodies may be movable toward or away from each other in the first width direction by elastic deformation of at least one of the side bodies.

[0014] In the above-mentioned auxiliary device, each of the pair of side bodies may be supported so as to be tiltable relative to the base body so that the upper ends of the pair of side bodies are close to or farther apart in the first width direction.

[0015] In the above-mentioned assisting tool, the base body may be a rod-shaped body extending in the first width direction.

[0016] In the above-mentioned auxiliary device, the rod-shaped bodies may be provided in pairs spaced apart in the second width direction, and each of the pair of rod-shaped bodies may connect the ends of the pair of side bodies in the second width direction to each other.

[0017] In the above-described assisting tool, the base body may be a rod-shaped body extending in the first width direction, and the gap adjustment mechanism may be a mechanism for extending and contracting the rod-shaped body.

[0018] In the above assisting tool, each of the pair of side bodies may be formed into a frame shape by a rod-like member that forms the outer shape of the side body.

[0019] In the above-mentioned auxiliary device, each of the pair of side bodies is frame-shaped and made up of rod-shaped members that form the outer shape of the side body, and the rod-shaped members have vertical bars extending in the up-down direction and horizontal bars extending in the second width direction, and the height adjustment mechanism may be a mechanism that extends and contracts the vertical bars.

[0020] In the above-mentioned auxiliary tool, in each of the pair of side bodies, the distance in the second width direction between the first outer support surface and the second outer support surface may be 150 mm or more.

[0021] In the above-mentioned auxiliary device, in each of the pair of side bodies, the distance from the connection portion between the first outer support surface and the first lower support surface to the upper end of the first outer support surface, and the distance from the connection portion between the second outer support surface and the second lower support surface to the upper end of the second outer support surface may be 150 mm or more.

[0022] In the above-mentioned assisting tool, the distance between the pair of side bodies in the first width direction may be greater than 250 mm. [Effects of the Invention]

[0023] The above-described auxiliary tool makes it possible to simplify the work of transporting container bags while keeping costs down. [Brief explanation of the drawings]

[0025] An assisting device 100 according to an embodiment of the present invention will be described below. As shown in Fig. 1, the assisting device 100 is used by being placed on top of a flexible container bag CN, and assists in the task of hanging the hoisting belts B of the container bag CN on a hoisting device. Here, the container bag CN is provided with a plurality of hoisting belts B.

[0026] In this embodiment, two hoisting belts B, i.e., a first hoisting belt B1 and a second hoisting belt B2, are arranged at positions spaced apart from each other in the width direction of the container bag CN (a direction that coincides with a second width direction W2 described later), and are provided so as to extend in a first width direction W1 described later. Also, the hoisting device of this embodiment is a forklift, and the auxiliary tool 100 will be described as an example in which it assists in the work of putting the hoisting belts B on the forks F of the forklift.

[0027] (Overall composition) As shown in Figure 2, the auxiliary device 100 comprises a pair of side bodies 1 arranged at an interval in a first width direction W1 that intersects with the up-down direction D1, and a base body 2 that connects the pair of side bodies 1 to each other.

[0028] (lateral body) Each of the pair of side bodies 1 extends in a second width direction W2 that intersects the up-down direction D1 and the first width direction W1. An arrangement space S is formed between the pair of side bodies 1, into which a fork F (see FIG. 1) can be inserted from the second width direction W2. Each side body 1 is frame-shaped and composed of rod-shaped members 10 that define its outer shape. The rod-shaped members 10 have vertical rods 11 extending in the up-down direction D1 and horizontal rods 12 extending in the second width direction W2. These vertical rods 11 and horizontal rods 12 are, for example, cylindrical tubes, but may be any rod-shaped member, including solid rods. Each side body 1 has a shape that is bilaterally symmetrical with respect to the second width direction W2 when viewed from the front from the outside in the first width direction W1.

[0029] More specifically, as shown in Figure 3(a), the horizontal bars 12 include a lower horizontal bar 12a located at the lowest position on each side body 1, a pair of upper horizontal bars 12b located at the highest position parallel to the lower horizontal bar 12a and spaced apart in the second width direction W2, and an intermediate horizontal bar 12c located between the pair of upper horizontal bars 12b in the second width direction W2, parallel to the lower horizontal bar 12a and the upper horizontal bar 12b, and located between the lower horizontal bar 12a and the upper horizontal bar 12b in the vertical direction D1.

[0030] The vertical bars 11 include a pair of outer vertical bars 11a spaced apart in the second width direction W2, each connecting a lower horizontal bar 12a and a corresponding upper horizontal bar 12b, and a pair of inner vertical bars 11b spaced apart in the second width direction W2 and located more inward in the second width direction W2 than the pair of outer vertical bars 11a, connecting an intermediate horizontal bar 12c and a corresponding upper horizontal bar 12b. Here, the "inside of the second width direction W2" refers to the side closer to the center of each side body 1 in the second width direction, and the side opposite the inside, which is the side away from the center, is referred to as the "outside of the second width direction W2."

[0031] Each outer vertical bar 11a extends upward at a right angle from the outer end of the lower horizontal bar 12a in the second width direction W2 and is connected to the outer end of the corresponding upper horizontal bar 12b in the second width direction W2 at a right angle to the upper horizontal bar 12b. Each inner vertical bar 11b extends downward at a right angle from the inner end of the corresponding upper horizontal bar 12b in the second width direction W2 and is connected to the outer end of the corresponding middle horizontal bar 12c in the second width direction W2 at a right angle to the middle horizontal bar 12c. Therefore, the pair of outer vertical bars 11a, the pair of upper horizontal bars 12b, and the pair of inner vertical bars 11b form protrusions 33 at both outer ends in the second width direction W2 on the upper part of each side body 1.

[0032] (Outside support surface) Of the pair of inner vertical bars 11b, the surface of one inner vertical bar 11b facing inward in the second width direction W2 is a first outer support surface 21, and the surface of the other inner vertical bar 11b facing inward in the second width direction W2 is a second outer support surface 22. The first outer support surface 21 is capable of supporting the first suspension belt B1 from the outside in the second width direction W2. The second outer support surface 22 is capable of supporting the second suspension belt B2 from the outside in the second width direction W2.

[0033] (Lower support surface) Of the upward-facing surfaces of the intermediate cross bar 12c, one region in the second width direction W2, based on the central portion of the side body 1 in the second width direction W2, serves as a first lower support surface 31, and the other region in the second width direction W2 serves as a second lower support surface 32. Therefore, the second lower support surface 32 is disposed adjacent to the first lower support surface 31 in the second width direction W2. The first lower support surface 31 is exposed upward and extends in the second width direction W2 so as to be able to support the first suspension belt B1 from below. Similarly, the second lower support surface 32 is exposed upward and extends in the second width direction W2 so as to be able to support the second suspension belt B2 from below.

[0034] That is, the first outer support surface 21 extends perpendicularly upward from the end of the first lower support surface 31 opposite to the second lower support surface 32 (the outer end in the second width direction W2), and the first lower support surface 31 and the first outer support surface 21 form an L-shape (or an inverted L-shape) in a front view of the side body 1 seen from one side in the first width direction W1. Similarly, the second outer support surface 22 extends perpendicularly upward from the end of the second lower support surface 32 opposite to the first lower support surface 31 (the outer end in the second width direction W2), and the second lower support surface 32 and the second outer support surface 22 form an inverted L-shape (or an L-shape) in a front view of the side body 1 seen from one side in the first width direction W1. The first lower support surface 31, the second lower support surface 32, the first outer support surface 21, and the second outer support surface 22 form a recess 34 in the upper part of each side body 1, and the first suspension belt B1 and the second suspension belt B2 are arranged between the interiors of the recesses 34 in the pair of side bodies 1.

[0035] (height adjustment mechanism) As shown in Figures 3(a) and 3(b), each of the pair of side bodies 1 has a height adjustment mechanism 40 that can change the position in the up-down direction D1 of a connection portion P1 between the first lower support surface 31 and the first outer support surface 21, and the position in the up-down direction D1 of a connection portion P2 between the second lower support surface 32 and the second outer support surface 22. The height adjustment mechanism 40 of this embodiment is a mechanism that extends and contracts each outer vertical rod 11a. Specifically, each outer vertical rod 11a has a structure in which an inner rod (hollow or solid rod) 11y is inserted into an outer cylinder 11x, and the insertion amount of the inner rod 11y into the outer cylinder 11x is adjustable. The height adjustment mechanism 40 is composed of an adjustment bolt 11z that can pass through the outer tube 11x and contact the outer peripheral surface of the inner rod 11y.By loosening the adjustment bolt 11z to determine the relative position between the outer tube 11x and the inner rod 11y and then tightening the adjustment bolt 11z, the adjustment bolt 11z comes into contact with the inner rod 11y, thereby regulating the relative movement between the outer tube 11x and the inner rod 11y.

[0036] As shown in FIG. 4, the spacing dimension d1 between a pair of side bodies 1 in the first width direction W1, which is the dimension of the arrangement space S in the first width direction W1, is preferably greater than 250 mm, more preferably greater than 280 mm, and even more preferably greater than 400 mm. The spacing dimension d1 is preferably 500 mm or less. In other words, the spacing dimension d1 between the side bodies 1 is preferably greater than the fork opening width of a forklift (rated load 0.9 to 3.5 tons) commonly used to transport container bags CN. The "fork opening width" here refers to the sum of the width dimensions of each of the two forks (the width dimensions of each of the two forks when the forks are attached) plus the spacing dimension between the two forks (the spacing dimension between the forks when the forks are attached). Furthermore, it is preferable that the spacing dimension d1 is a dimension that allows a pair of side bodies 1 to be placed on a commonly used container bag (with a load capacity of 0.5t to 2.0t), i.e., a dimension that does not allow the auxiliary device 100 to protrude from the container bag in the first width direction W1 and the second width direction W2.

[0037] Returning to Figure 3, so that each of the suspension belts B1, B2 in each side body 1 is supported in contact with the first outer support surface 21 or the second outer support surface 22, the distance d2 in the second width direction W2 between the first outer support surface 21 and the second outer support surface 22 is preferably narrower than the distance in the first width direction W2 between the positions where each of the suspension belts is connected to the container bag in a commonly used container bag (with a load capacity of 0.5 to 2.0 tons), and is preferably 150 mm or more.

[0038] In addition, so that each suspension belt B in each side body 1 is supported in contact with the first outer support surface 21 or the second outer support surface 22, the distance h1 from the connection between the first lower support surface 31 and the first outer support surface 21 to the upper end of the first outer support surface 21, and the distance h2 from the connection between the second lower support surface 32 and the second outer support surface 22 to the upper end of the second outer support surface 22 are preferably larger than the tape width of each suspension belt of a commonly used container bag (with a load capacity of 0.5 to 2.0 tons), and are preferably 150 mm or more.

[0039] Furthermore, the dimension d3 in the second width direction W2 of each side body 1 is preferably smaller than 1500 mm. In other words, the dimension d3 is preferably smaller than the fork length of a commonly used forklift (with a rated load of 0.9 tons to 3.5 tons).

[0040] (base body) Returning to FIG. 2 , the base body 2 connects the pair of side bodies 1 together, defines the bottom of the arrangement space S, and is placed in contact with the top of the container bag CN. In this embodiment, the base body 2 is a rod-shaped body extending in the first width direction W1. This rod-shaped body is, for example, a cylindrical tube, but it may be any rod-shaped body, even a solid rod. A pair of rod-shaped bodies serving as the base body 2 are provided so as to be spaced apart in the second width direction W2 and are arranged parallel to each other, connecting the outer end of one side body 1 in the second width direction W2 to the outer end of the other side body 1 in the second width direction W2.

[0041] (Space adjustment mechanism) As shown in FIG. 4 , the rod-shaped body serving as the base body 2 has a gap adjustment mechanism 50 that can change the distance d1 between the pair of side bodies 1 in the first width direction W1. In this embodiment, the gap adjustment mechanism 50 is a mechanism for extending and retracting the rod-shaped body. Specifically, the rod-shaped body has an inner rod (hollow or solid rod) 2y inserted into an outer tube 2x, allowing the insertion amount of the inner rod 2y into the outer tube 2x to be adjusted. In each rod-shaped body, the outer tubes 2x are spaced apart in the first width direction W1, and the inner rod 2y is sandwiched between the outer tubes 2x. The gap adjustment mechanism 50 is composed of an adjustment bolt 2z that penetrates each outer tube 2x and can contact the outer peripheral surface of the inner rod 2y. After loosening the adjustment bolt 2z to determine the relative position between the outer tube 2x and the inner rod 2y, the adjustment bolt 2z is tightened to bring the adjustment bolt 2z into contact with the inner rod 2y, restricting the relative movement between the outer tube 2x and the inner rod 2y.

[0042] In addition, in the rod-shaped body serving as the base body 2 of this embodiment, at least the inner rod 2y is flexible enough to be elastically bent and deformed by the force of an operator. On the other hand, the outer cylinder 2x is formed of a material with a higher flexural modulus than the inner rod 2y. Therefore, as shown in Figure 5, when an external force O is applied from the outside (or inside) in the first width direction W1 so as to bend the rod-shaped body serving as the base body 2, the inner rod 2y, which has a lower elastic modulus, elastically deforms, allowing the upper ends of the pair of side bodies 1 to move closer to or farther apart in the first width direction W1.

[0043] (Action and effect) According to the auxiliary tool 100 of the present embodiment described above, the first lower support surface 31 is connected to the first outer support surface 21, and the second lower support surface 32 is connected to the second outer support surface 22, thereby forming a recess 34 in the upper part of the side body 1. Therefore, by arranging the suspending belts B1, B2 inside this recess 34, the suspending belts B1, B2 can be easily arranged on the auxiliary tool 100. At this time, the first suspending belt B1 is supported from the outside in the second width direction W2 by the first outer support surface 21 and from below by the first lower support surface 31, so that the first suspending belt B1 can be held in the upper part of the arrangement space S for arranging the forks F. Similarly, the second suspending belt B2 is supported from the outside in the second width direction W2 by the second outer support surface 22 and from below by the second lower support surface 32, so that the second suspending belt B2 can be held in the upper part of the arrangement space S.

[0044] Therefore, by simply lifting the fork F while the fork F is inserted in the arrangement space S below the hoisting belts B, the hoisting belts B1 and B2 can be put around the fork F. Furthermore, once the worker dismounts from the forklift and places the hoisting belts B1 and B2 in the recesses 34 of the side body 1, the worker can then easily adjust the position at which the hoisting belts B are put around the fork F by adjusting the insertion position of the fork F in the arrangement space S while getting back on the forklift. In other words, even if there is only one worker, there is no need to repeatedly get on and off the forklift to adjust the positions of the hoisting belts B1 and B2 and re-hang the hoisting belts B1 and B2 around the fork F.

[0045] By using the auxiliary device 100 of this embodiment in this manner, the lifting belts B1 and B2 can be easily attached to the fork F at the optimum position for lifting the container bag CN, thereby facilitating the transportation of the container bag CN.

[0046] Furthermore, when the fork F is inserted into the arrangement space S and lifted above the side body 1, the first suspending belt B1 moves from a state in which it is supported by the first outer support surface 21 to above the first outer support surface 21, i.e., above (outside) the recess 34, and is released from support by the auxiliary device 100. Similarly, the second suspending belt B2 is released from support by the auxiliary device 100. In this state in which the suspending belts B1 and B2 are lifted by the fork F, the fork F separates from the auxiliary device 100, and the suspending belts B1 and B2 also separate from the auxiliary device 100. In this state, the auxiliary device 100 alone can be removed from the container bag CN. Therefore, after removing the auxiliary device 100 from one container bag CN, it can be attached (placed) on another container bag CN for use. This allows the auxiliary device 100 to be reused, eliminating the need to prepare as many auxiliary devices 100 as there are container bags CN to be transported, thereby reducing costs.

[0047] Furthermore, since the base body 2 has the spacing adjustment mechanism 50, the spacing between the side bodies 1 can be easily adjusted. Therefore, the spacing between the side bodies 1 can be changed to match the size of the container bag CN, increasing the versatility of the auxiliary device 100. Furthermore, the spacing adjustment mechanism 50 can increase or decrease the dimension of the arrangement space S in the first width direction W1 to match the size of the fork F, making it possible to accommodate forklifts of various models and sizes, thereby also increasing versatility in this respect.

[0048] Furthermore, since each side body 1 has a height adjustment mechanism 40, the position of the recess 34 can be adjusted up or down according to the length of the lifting belts B1, B2 in the first width direction W1, i.e., according to the size of the container bag CN, thereby reducing the slack of the lifting belts B1, B2. Reducing the slack of the lifting belts B1, B2 makes it easier to insert the fork F into the arrangement space S below the lifting belts B1, B2.

[0049] Furthermore, since the base body 2 is flexible, by bending and deforming the base body 2, the upper ends of the side bodies 1 can be moved closer to or farther apart. Even if the hanging belts B1 and B2 remain positioned within the recess 34 when lifted by the fork F, the auxiliary device 100 can be deformed so that the hanging belts B1 and B2 move away from the auxiliary device 100, and the auxiliary device 100 can be easily removed from the container bag CN.

[0050] Furthermore, because the base body 2 is rod-shaped, the distance adjustment mechanism 50 can be configured very easily. That is, the distance between the side bodies 1 can be adjusted simply by extending or retracting the rod-shaped body. Furthermore, because the base body 2 is rod-shaped, the weight of the base body 2 can be reduced, which leads to a reduction in the weight of the auxiliary device 100 and makes it easier to carry the auxiliary device 100. Furthermore, a pair of rod-shaped bodies as the base body 2 are provided to connect the end of one side body 1 to the end of the other side body 1. Therefore, the strength of the side body 1 can be sufficiently ensured, and the stability of the auxiliary device 100 when placed on the container bag CN can be improved.

[0051] Furthermore, because each side body 1 is made up of rod-shaped members 10, the height adjustment mechanism 40 can be constructed very simply. That is, the position of the recess 34 can be raised or lowered simply by extending or contracting the outer vertical rod 11a of the rod-shaped members 10. Furthermore, because the side body 1 is made up of rod-shaped members 10, the weight of the side body 1 can be reduced, which leads to a reduction in the weight of the assisting device 100, making it easier to carry the assisting device 100.

[0052] Furthermore, if the spacing dimension d1 in the first width direction W1 between the side bodies 1 is greater than 250 mm, the forks of a commonly used forklift can be securely inserted into the placement space S, so the auxiliary device 100 can be used regardless of the model or size of the forklift, increasing its versatility.

[0053] Furthermore, if the distance d2 in the second width direction W2 between the first outer support surface 21 and the second outer support surface 22 is 150 mm or more, the suspension belts of a commonly used container bag CN can be reliably positioned within the recesses 34. Therefore, the auxiliary tool 100 can be used regardless of the size of the container bag CN, increasing its versatility.

[0054] Furthermore, if the distance h1 from the connection portion P1 between the first outer support surface 21 and the first lower support surface 31 to the upper end of the first outer support surface 21, and the distance h2 from the connection portion P2 between the second outer support surface 22 and the second lower support surface 32 to the upper end of the second outer support surface 22 are 150 mm or more, the suspension belts of commonly used container bags can be reliably supported by the first outer support surface 21 and the second outer support surface 22. Therefore, the auxiliary tool 100 can be used regardless of the size of the container bag CN, increasing its versatility.

[0055] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. 6, the first outer support surface 61 and the second outer support surface 62 may be inclined outward in the second width direction W2 as they extend upward. In this case, when the fork F is inserted into the arrangement space S and then lifted above the side body 1, the suspending belts B1 and B2 are smoothly guided upward by the first outer support surface 21 and the second outer support surface 22 from a state in which they are supported by the first outer support surface 61 and the second outer support surface 62, and are released from support by the assisting device 100. Therefore, the assisting device 100 can be easily removed from the container bag simply by lifting the suspending belts B1 and B2 with the fork F.

[0056] 7, each side body 1 may be supported by a hinge or the like so that the upper ends of the pair of side bodies 1 can be tilted relative to the base body 2 so that they approach or move apart in the first width direction W1. In this case, if an external force O is applied to tilt the side bodies 1 so that the upper ends of the side bodies 1 move closer to or apart from each other, the auxiliary device 100 can be easily removed from the container bag CN even in a situation where the hoisting belts B1, B2 remain positioned in the recesses 34 when they are lifted by the forks F.

[0057] 8, the first lower support surface 31 and the second lower support surface 32 may be disposed at positions spaced apart in the second width direction W2, and a convex portion 37 protruding upward may be formed between the first lower support surface 31 and the second lower support surface 32.
