Description

[Technical Field]

[0001] The present invention relates to a lifting jig used when transporting an object to be transported, and a transport jig transport system using the lifting jig. [Background technology]

[0002] In recent years, mechanization of transportation has progressed regardless of the type of object to be transported, and development of transport jigs for transporting objects and systems for transporting transport jigs has progressed.

[0003] Patent document 1 describes an automatic parts handling device that is characterized by comprising a separator unit that stores pallets inside boxes with hooks on the sides and keeps the boxes separated vertically from a vertically stacked state, a lifter unit that takes out any one of the multiple boxes separated by the separator unit and lowers it to a predetermined height, a conveying unit that receives the box from the lifter unit and moves it horizontally to a predetermined position, and an elevator unit that receives the box from the conveying unit and raises only the pallet inside the box to supply the parts to a parts assembly processing device.

[0004] Patent Document 2 describes a foldable cargo receptacle or container having a bottom plate member, side wall members, and a top plate member, which are immovably connected to each other when assembled. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 61-33423 [Patent Document 2] Japanese Patent Application Publication No. 5-254590 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the device described in Patent Document 1 and the vessel or container described in Patent Document 2 still have room for improvement in terms of functionality when lifting them from a predetermined location and placing them in another location.

[0007] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a lifting jig and transport jig transport system that has the function of making it easy to lift at a specified position and to make it easy to place at a desired location. [Means for solving the problem]

[0008] One embodiment of the lifting jig of the present invention that can solve the above problem is a lifting jig that lifts a transport jig having a protrusion, and has a first receiving portion that defines a first space that receives the protrusion, and a second receiving portion that is arranged in a position different from the first receiving portion and defines a second space that receives the protrusion, and the gist of the lifting jig lies in that the outer shape of the first space when the first receiving portion is observed from the protruding direction of the protrusion when the first receiving portion receives the protrusion differs from the outer shape of the second space when the second receiving portion is observed from the protruding direction of the protrusion when the second receiving portion receives the protrusion. The first receiving portion and second receiving portion of the lifting jig receive the protrusion of the transport jig, allowing the transport jig to be lifted. In this case, the outer shape of the first space when the first receiving portion is observed from the protruding direction of the protrusion when the first receiving portion receives the protrusion differs from the outer shape of the second space when the second receiving portion is observed from the protruding direction of the protrusion when the second receiving portion receives the protrusion. As a result, even if there is a discrepancy between the distance between the first receiving portion and the second receiving portion and the distance between the protrusion received by the first receiving portion and the protrusion received by the second receiving portion, the protrusion can move in the receiving portion with the wider stable area as the protrusion is positioned in accordance with the receiving portion with the narrower stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion and the second receiving portion, making it easier to place the transport jig at a desired location.

[0009] It is preferable that the outer shape of the first space has a predetermined section in which its width in the horizontal direction narrows downward, and that the outer shape of the second space does not have a predetermined section in which its width in the horizontal direction narrows downward.

[0010] In a state where the first receiving portion receives the protruding portion and lifts up the transport jig, it is preferable that a portion of the first receiving portion that is present in the predetermined section and the protruding portion abut against each other.

[0011] It is preferable that the first space has a triangular outer shape, and the second space has a rectangular outer shape.

[0012] When the first receiving portion and the second receiving portion receive the protrusion and lift the conveying jig, it is preferable that the second receiving portion abuts the lowest part of the protrusion in the vertical direction, and that the first receiving portion does not abut the lowest part of the protrusion in the vertical direction.

[0013] In a state in which the second receiving portion receives the protruding portion and lifts up the transport jig, it is preferable that the protruding portion received by the second receiving portion be movable in the horizontal direction.

[0014] In a state in which the first receiving portion receives the protruding portion and lifts up the transport jig, it is preferable that the protruding portion received by the first receiving portion cannot move in the horizontal direction.

[0015] It is preferable that the number of first receiving portions is the same as the number of second receiving portions.

[0016] One embodiment of the transport jig transport system of the present invention, which has solved the above-mentioned problem, is characterized by including the lifting jig and a transport jig having a first protrusion received by a first receiving portion and a second protrusion received by a second receiving portion. The first receiving portion and the second receiving portion of the lifting jig receive the first protrusion and the second protrusion of the transport jig, thereby lifting the transport jig. In this case, the outer shape of the first space when the first receiving portion is observed from the protruding direction of the first protrusion when the first receiving portion receives the first protrusion differs from the outer shape of the second space when the second receiving portion is observed from the protruding direction of the second protrusion when the second receiving portion receives the second protrusion. As a result, the area in which the first protrusion is stable on the first receiving portion and the area in which the second protrusion is stable on the second receiving portion differ. As a result, even if there is a discrepancy between the distance between the first receiving portion and the second receiving portion and the distance between the first protruding portion and the second protruding portion, the protruding portion can be positioned to fit the receiving portion with the narrower stable area, and the protruding portion can move in the receiving portion with the wider stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion and the second receiving portion, making it easier to place the transport jig in a desired location.

[0017] Preferably, the first receiving portion is capable of receiving the second protrusion, and the second receiving portion is capable of receiving the first protrusion. [Effects of the Invention]

[0018] The lifting jig and transport jig transport system of the present invention makes it easy to lift the transport jig at a predetermined position relative to the first receiving portion and the second receiving portion, making it easy to place the transport jig at the desired location.

[0020] The present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the illustrated examples, and appropriate modifications may be made within the scope of the spirit described above and below, and all such modifications are within the technical scope of the present invention. In the drawings, hatching and symbols may be omitted for convenience. In such cases, reference should be made to the specification and other drawings. Furthermore, the dimensions of various parts in the drawings may differ from the actual dimensions, as priority is given to helping understand the features of the present invention.

[0021] One embodiment of the lifting jig of the present invention is a lifting jig that lifts a transport jig having a protrusion, and has a first receiving portion that defines a first space that receives the protrusion, and a second receiving portion that is arranged in a position different from the first receiving portion and defines a second space that receives the protrusion, and the gist of the lifting jig is that the outer shape of the first space when the first receiving portion is observed from the protruding direction of the protrusion when the first receiving portion receives the protrusion is different from the outer shape of the second space when the second receiving portion is observed from the protruding direction of the protrusion when the second receiving portion receives the protrusion.

[0022] First, the overall configuration of the lifting jig will be described with reference to Figures 1 to 6. In these figures, the horizontal direction is indicated by x and the vertical direction is indicated by y. The horizontal direction x is a direction perpendicular to the vertical direction y, but Figures 1 to 6 only show one direction perpendicular to the vertical direction y.

[0023] Fig. 1 is a perspective view showing an example of a lifting jig according to an embodiment of the present invention. As shown in Fig. 1, the lifting jig 1 is used to lift a transport jig having a protrusion, which will be described later.

[0024] 2 is a perspective view showing an example of a transport jig that is lifted by a lifting jig according to an embodiment of the present invention. As shown in FIG. 2, the transport jig 100 has a protrusion 110 and is lifted by the lifting jig 1.

[0025] As shown in FIG. 1, the lifting jig 1 has a first receiving portion 10 that receives the protrusion, and a second receiving portion 20 that is arranged at a different position from the first receiving portion 10 and also receives the protrusion.

[0026] Figure 3 is an enlarged front view of the first receiving portion 10 of the lifting jig 1 shown in Figure 1, and shows the state in which the first receiving portion 10 is observed from the protruding direction of the protruding portion 110 when the first receiving portion 10 receives the protruding portion 110, and shows the state in which the first receiving portion 10 is receiving the protruding portion 110.

[0027] Figure 4 is an enlarged front view of the second receiving portion 20 of the lifting jig 1 shown in Figure 1, and shows the state in which the second receiving portion 20 is observed from the protruding direction of the protrusion 110 when the second receiving portion 20 receives the protrusion 110, and shows the state in which the second receiving portion 20 is receiving the protrusion 110.

[0028] FIG. 5 is a front view showing a modified example of the first receiving portion 10 shown in FIG. 3, showing a state in which the protrusion 110 is received.

[0029] 3 and 5, the first receiving portion 10 defines a first space 14 that receives the protrusion 110. As shown in Fig. 3 and 5, the first space 14 is a space surrounded by the first receiving portion 10. In Fig. 3, the boundary between the first space 14 and the outside is indicated by a two-dot chain line.

[0030] As shown in Fig. 4, the second receiving portion 20 defines a second space 24 that receives the protrusion 110. As shown in Fig. 4, the second space 24 is a space surrounded by the second receiving portion 20. In Fig. 4, the boundary between the second space 24 and the outside is indicated by a two-dot chain line.

[0031] 1 , 3 , and 4 show an embodiment in which the outer shape of the first space 14 when the first receiving portion 10 is observed from the protruding direction of the protrusion 110 when the first receiving portion 10 receives the protrusion 110 differs from the outer shape of the second space 24 when the second receiving portion 20 is observed from the protruding direction of the protrusion 110 when the second receiving portion 20 receives the protrusion 110. In this specification, the outer shape of the first space 14 when the first receiving portion 10 is observed from the protruding direction of the protrusion 110 when the first receiving portion 10 receives the protrusion 110 will be simply referred to as the outer shape of the first space 14. Similarly, the outer shape of the second space 24 when the second receiving portion 20 is observed from the protruding direction of the protrusion 110 when the second receiving portion 20 receives the protrusion 110 will be simply referred to as the outer shape of the second space 24.

[0032] 3 to 5, the first receiving portion 10 and the second receiving portion 20 of the lifting jig 1 receive the protrusion 110 of the transport jig, and the first receiving portion 10 and the second receiving portion 20 move upward, thereby lifting the transport jig. At this time, the outer shape of the first space 14 when the first receiving portion 10 is observed from the protruding direction of the protrusion 110 when the first receiving portion 10 receives the protrusion 110 differs from the outer shape of the second space 24 when the second receiving portion 20 is observed from the protruding direction of the protrusion 110 when the second receiving portion 20 receives the protrusion 110. As a result, the area in the first receiving portion 10 where the protrusion 110 is stable and the area in the second receiving portion 20 where the protrusion 110 is stable differ. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the protrusion 110 received by the first receiving portion 10 and the protrusion 110 received by the second receiving portion 20, the protrusion 110 is positioned to fit the receiving portion with the narrower stable area, and the protrusion 110 can move in the receiving portion with the wider stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig in a desired location.

[0033] FIG. 6 is a perspective view showing a modified example of the lifting jig according to the embodiment of the present invention.

[0034] The outer shapes of the first space 14 and the second space 24 are not particularly limited as long as they are different from each other. For example, they may be semicircular, circular, oval, polygonal, star-shaped, or a combination of these. Note that oval shapes include ellipses and ovals. Polygons may have rounded corners. As shown in FIG. 3, the outer shape of the first space 14 may be triangular, and as shown in FIG. 4, the outer shape of the second space 24 may be rectangular. Furthermore, as shown in FIG. 6, the outer shape of the first space may be triangular, and the outer shape of the second space may be semicircular.

[0035] The area in which the protrusion 110 is stable in the first receiving portion 10 can be configured to be narrower than the area in which the protrusion 110 is stable in the second receiving portion 20. Also, the area in which the protrusion 110 is stable in the first receiving portion 10 can be configured to be wider than the area in which the protrusion 110 is stable in the second receiving portion 20.

[0036] 3 and 5, in the lifting jig 1, it is preferable that the width 11 in the horizontal direction x of the outline of the first space 14 has a section that is narrower than the maximum width 112 in the horizontal direction x of the protrusion 110. It is preferable that the width 11 in the horizontal direction x of the lower half of the outline of the first space 14 has a section that is narrower than the maximum width 112 in the horizontal direction x of the protrusion 110. This configuration makes it easier to narrow the area in the first receiving part 10 where the protrusion 110 is stable when the transport jig is lifted by receiving the protrusion 110.

[0037] It is preferable that the lower half of the outer shape of the second space 24 does not have a predetermined section in which the width 21 in the horizontal direction x narrows downward. In this case, the upper half of the outer shape of the second space 24 may have a predetermined section in which the width 21 in the horizontal direction x narrows downward. As shown in FIG. 4 , it is preferable that the outer shape of the second space 24 does not have a predetermined section in which the width 21 in the horizontal direction x narrows downward. By not having a predetermined section in which the width 21 in the horizontal direction x narrows downward in the lower half or the entire outer shape of the second space 24, it is possible to easily widen the area in which the protrusion 110 of the second receiving portion 20 is stable when the transport jig is lifted by receiving the protrusion 110.

[0038] Preferably, the outer shape of the first space 14 has a predetermined section 12 in which the width 11 in the horizontal direction x narrows downward, and the outer shape of the second space 24 does not have a predetermined section in which the width 21 in the horizontal direction x narrows downward. This configuration makes it possible to make the area in the first receiving portion 10 where the protrusion 110 is stable narrower than the area in the second receiving portion 20 where the protrusion 110 is stable. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the protrusion 110 received by the first receiving portion 10 and the protrusion 110 received by the second receiving portion 20, the protrusion 110 can move in the second receiving portion 20 where the stable area is wider as the protrusion 110 is positioned in the first receiving portion 10 with the narrower stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig at a desired location.

[0039] Although not shown, the outer shape of the second space may have a section whose width in the horizontal direction x increases downward. Also, as shown in Fig. 4, the outer shape of the second space 24 may be set so that the width 21 in the horizontal direction x is the same regardless of the location. By adopting such a configuration, it is possible to easily widen the area in which the protrusion in the second receiving portion is stable when the first receiving portion and the second receiving portion receive the protrusion and lift the transport jig.

[0040] Although the lower half of the outer shape of the second space or the entire outer shape of the second space can be configured to have a section in which the width in the horizontal direction x narrows downward, in that case, it is preferable that the width in the horizontal direction of the outer shape of the second space does not have a section narrower than the maximum width in the horizontal direction of the protrusion. This makes it easier to widen the area in which the protrusion is stable on the second receiving part when the first receiving part and the second receiving part receive the protrusion and lift the transport jig.

[0041] In the vertical direction y, the position of the lowest point of the outer shape of the first space 14 and the position of the lowest point of the outer shape of the second space 24 may be the same or different. For example, if the lifting jig has a first receiving portion where the outer shape of the first space is semicircular and a second receiving portion where the outer shape of the second space is rectangular, it is preferable that the position of the lowest point of the outer shape of the first space and the position of the lowest point of the outer shape of the second space are the same. If the lifting jig 1 has a first receiving portion 10 where the outer shape of the first space 14 is triangular as shown in FIG. 3 and a second receiving portion 20 where the outer shape of the second space 24 is rectangular as shown in FIG. 4, it is preferable that the position of the lowest point of the outer shape of the first space 14 and the position of the lowest point of the outer shape of the second space 24 are different in the vertical direction y, and it is more preferable that the position of the lowest point of the outer shape of the first space 14 is located lower than the position of the lowest point of the outer shape of the second space 24. By using a lifting jig 1 having this configuration, it is possible to lift a conveying jig 100 in which the position in the vertical direction y of the protrusion 110 received by the first receiving portion 10 and the position in the vertical direction y of the protrusion 110 received by the second receiving portion 20 are aligned, making it easier to increase stability when lifted.

[0042] 3 and 5 , when the first receiving portion 10 receives the protrusion 110 and lifts the transport jig 100, it is preferable that the portion of the first receiving portion 10 located in the predetermined section 12 abuts against the protrusion 110. This configuration makes it easier to make the area in the first receiving portion 10 where the protrusion 110 is stable narrower than the area in the second receiving portion 20 where the protrusion 110 is stable. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the protrusion 110 received by the first receiving portion 10 and the protrusion 110 received by the second receiving portion 20, the protrusion 110 can move in the second receiving portion 20 where the stable area is wider as the protrusion 110 is positioned to fit the first receiving portion 10 with the narrower stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig at a desired location.

[0043] When the first receiving portion 10 and the second receiving portion 20 receive the protrusion 110 and hoist the transport jig 100, it is preferable that the second receiving portion 20 abuts against the lowermost portion 111 of the protrusion 110 in the vertical direction y, as shown in Fig. 4. Furthermore, when the first receiving portion 10 and the second receiving portion 20 receive the protrusion 110 and hoist the transport jig 100, it is preferable that the first receiving portion 10 does not abut against the lowermost portion 111 of the protrusion 110 in the vertical direction y, as shown in Figs. 3 and 5. With this configuration, it is possible to make it easier to make the area in which the protrusion 110 is stable on the first receiving portion 10 narrower than the area in which the protrusion 110 is stable on the second receiving portion 20. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the protrusion 110 received by the first receiving portion 10 and the protrusion 110 received by the second receiving portion 20, the protrusion 110 is arranged to fit the first receiving portion 10 having a narrower stable area, and the protrusion 110 can move in the second receiving portion having a wider stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig in a desired location.

[0044] When the second receiving portion 20 receives the protrusion 110 and lifts the transport jig 100, it is preferable that the protrusion 110 received by the second receiving portion 20 be movable in the horizontal direction x. When the second receiving portion 20 receives the protrusion 110 and lifts the transport jig 100, it is also preferable that the protrusion 110 received by the second receiving portion 20 be movable in the width 21 direction of the outer shape of the second space 24. For example, as shown in FIG. 4 , if the outer shape of the second space 24 is rectangular, when the second receiving portion 20 receives and lifts the protrusion 110, the protrusion 110 is movable in the horizontal direction x, particularly in the width 21 direction of the outer shape of the second space 24. This makes it easier to widen the area in which the protrusion 110 is stable on the second receiving portion 20 when it is being lifted by the lifting jig 1, in the horizontal direction x, particularly in the width 21 direction of the outer shape of the second space 24.

[0045] When the first receiving portion 10 receives the protrusion 110 and suspends the transport jig 100, it is preferable that the protrusion 110 received by the first receiving portion 10 cannot move in the horizontal direction x. When the first receiving portion 10 receives the protrusion 110 and suspends the transport jig 100, it is also preferable that the protrusion 110 received by the first receiving portion 10 cannot move in the width 11 direction of the outer shape of the first space 14. For example, if the outer shape of the first space 14 is triangular as shown in FIG. 3 , when the first receiving portion 10 receives the protrusion 110 and suspends the transport jig 100, the protrusion 110 received by the first receiving portion 10 cannot move in the horizontal direction x, particularly in the width 11 direction of the outer shape of the first space 14. This makes it easier to narrow the area in which the protrusion 110 of the first receiving portion 10 is stable when lifted by the lifting jig 1 in the horizontal direction x, particularly in the width 11 direction of the outer shape of the first space 14.

[0046] It is preferable that when the second receiving portion 20 receives the protrusion 110 and hoists the transport jig 100, the protrusion 110 received by the second receiving portion 20 is movable in the horizontal direction x, and when the first receiving portion 10 receives the protrusion 110 and hoists the transport jig 100, the protrusion 110 received by the first receiving portion 10 is immovable in the horizontal direction x. It is also preferable that when the second receiving portion 20 receives the protrusion 110 and hoists the transport jig 100, the protrusion 110 received by the second receiving portion 20 is movable in the width 21 direction of the outer shape of the second space 24, and when the first receiving portion 10 receives the protrusion 110 and hoists the transport jig 100, the protrusion 110 received by the first receiving portion 10 is immovable in the width 11 direction of the outer shape of the first space 14. With this configuration, the area in which the protrusion 110 is stable in the first receiving portion 10 can be made narrower than the area in which the protrusion 110 is stable in the second receiving portion 20. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the protrusion 110 received by the first receiving portion 10 and the protrusion 110 received by the second receiving portion 20, the protrusion 110 can move in the second receiving portion 20, which has a wider stable area, as the protrusion 110 is positioned to fit the first receiving portion 10, which has a narrower stable area. This makes it easier to lift the transport jig at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig at a desired location.

[0047] The length of the predetermined section 12 of the contour of the first space 14 in the vertical direction y may be longer or shorter than the length of the maximum width 112 of the protrusion 110 in the horizontal direction x. The length of the predetermined section 12 of the contour of the first space 14 in the vertical direction y may be longer or shorter than half the length of the maximum width 112 of the protrusion 110. The length of the predetermined section 12 of the contour of the first space 14 in the vertical direction y may be the same as the length of the maximum width 112 of the protrusion 110.

[0048] The number of first receiving portions 10 may be one as shown in FIG. 6, two as shown in FIG. 1, or more. The same applies to the number of second receiving portions 20. When there are two or more first receiving portions 10, it is preferable that the first receiving portions 10 face each other in the protruding direction of the protrusion 110. The same applies to the second receiving portions 20. The number of first receiving portions 10 and the number of second receiving portions 20 may be the same or different, but it is preferable that the number of first receiving portions 10 and the number of second receiving portions 20 are the same. This makes it easier to balance the weight when the transport jig 100 is lifted by the lifting jig 1.

[0049] The first space 14 may be a hole formed in the first receiving portion 10 as shown in Fig. 5. Although not shown, the second space may also be a hole formed in the second receiving portion. In this case, it is preferable that the outer shape of the hole formed in the first receiving portion when observed from the depth direction of the hole formed in the first receiving portion differs from the outer shape of the hole formed in the second receiving portion when observed from the depth direction of the hole formed in the second receiving portion.

[0050] A portion of the first receiving portion 10 and the second receiving portion 20 may be fixed to a support portion 40 as shown in Figures 1 and 6. The support portion 40 is a portion for supporting the first receiving portion 10 and the second receiving portion 20.

[0051] Although not shown in detail, it is preferable that a part of the support portion is connected to a transport robot.

[0052] For example, as shown in FIGS. 3 to 5, the protrusion 110 can be received by the inner surface 13 of the first receiving portion 10 and the inner surface 23 of the second receiving portion 20.

[0053] The material constituting the lifting jig 1 is not particularly limited, but examples thereof include synthetic resin, natural resin, metal, and the like.

[0054] So far, the lifting jig 1 according to the embodiment of the present invention has been described. Next, a transport jig transport system will be described with reference to FIGS.

[0055] One embodiment of the transport jig transport system of the present invention is characterized in that it comprises the above-mentioned lifting jig 1 and a transport jig 100 having a first protrusion 110a received by the first receiving portion 10 and a second protrusion 110b received by the second receiving portion 20.

[0056] As shown in FIG. 2, the transport jig 100 has a first protrusion 110a that is received by the first receiving portion and a second protrusion 110b that is received by the second receiving portion.

[0057] The first receiving portion 10 and the second receiving portion 20 of the lifting jig 1 receive the first protrusion 110a and the second protrusion 110b of the transport jig 100, thereby lifting the transport jig 100. At this time, the outer shape of the first space 14 when the first receiving portion 10 is observed from the protruding direction of the first protrusion 110a when the first receiving portion 10 receives the first protrusion 110a is different from the outer shape of the second space 24 when the second receiving portion 20 is observed from the protruding direction of the second protrusion 110b when the second receiving portion 20 receives the second protrusion 110b. As a result, the area in the first receiving portion 10 where the first protrusion 110a is stable and the area in the second receiving portion 20 where the second protrusion 110b is stable are different. As a result, even if there is a discrepancy between the distance between the first receiving portion 10 and the second receiving portion 20 and the distance between the first protrusion 110a and the second protrusion 110b, the protrusion is positioned to fit the receiving portion with the narrower stable area, and the protrusion can move in the receiving portion with the wider stable area. This makes it easier to lift the transport jig 100 at a predetermined position relative to the first receiving portion 10 and the second receiving portion 20, making it easier to place the transport jig 100 in a desired location.

[0058] It is preferable that the first receiving portion 10 is capable of receiving the second protruding portion 110b, and the second receiving portion 20 is capable of receiving the first protruding portion 110a. This allows the lifting jig 1 to lift the transport jig 100 more smoothly and easily.

[0059] The shapes of first protrusion 110a and second protrusion 110b are not particularly limited, and may be rod-shaped, column-shaped, cylindrical, polygonal prism-shaped, or a combination of these shapes, etc. First protrusion 110a and second protrusion 110b may have the same shape or different shapes.

[0060] It is preferable that the first protrusion 110a and the second protrusion 110b extend in the horizontal direction x. This configuration can easily improve the stability when the transport jig 100 is lifted by the lifting jig 1.

[0061] The position of the lowest part 111a of the first protrusion 110a and the position of the lowest part 111b of the second protrusion 110b in the vertical direction y may be different, but it is preferable that they are the same. This configuration makes it easier to improve the stability when the transport jig 100 is lifted by the lifting jig 1.

[0062] The total number of first protrusions 110a and second protrusions 110b that the transporting jig 100 has may be the same as or different from the total number of first receiving portions 10 and second receiving portions 20 that the lifting jig 1 has.

[0063] The shape of the transport jig is not particularly limited, but may be bag-shaped or box-shaped as shown in FIG.

[0064] The material constituting the transport jig 100 is not particularly limited, but examples thereof include synthetic resin, natural resin, and metal.

[0065] The shape of the object to be transported that is placed in or fixed to the transport jig 100 is not particularly limited, but examples thereof include bag-shaped objects and box-shaped objects such as cubes and rectangular parallelepipeds. The weight of the object to be transported is also not particularly limited. More specific examples of the object to be transported include an electrical appliance package in which an electrical appliance such as a hand dryer or microwave oven is packaged in a cardboard box, and a medical device package in which a medical device such as a syringe or catheter is packaged in a bag. These objects to be transported are placed in or fixed to the transport jig 100 and transported. [Explanation of symbols]
