Description

[Technical field]

[0001] The present invention relates to a transport aid that can be used when performing loading and unloading work using a forklift. [Background technology]

[0002] When loading and unloading work is performed with a forklift, the cargo is lifted and transported with the cargo placed on a pallet or platform into which the forks can be inserted, or with the cargo placed on a timber beam and the forks inserted from underneath. In addition to a forklift operator riding on the vehicle to perform loading and unloading work, a forklift operation support device has been disclosed that recognizes where the cargo should be placed using a camera and a sensor mounted on the forklift and aligns the position by displaying a loading and unloading guide on a monitor (see, for example, Patent Document 1).

[0003] [Patent Document 1] Patent Publication No. 2021-031210 Summary of the Invention [Problem to be solved by the invention]

[0004] When using a forklift to handle cargo, if the center of gravity of the cargo on the platform is misaligned, the cargo may collapse. Because the platform on which the cargo is loaded is in the blind spot of the operator, in order to lower the cargo with the forks in line with the center of gravity of the platform, an assistant must guide the forklift, or the operator must get off the vehicle and check directly. This creates the problem of time and effort required to safely handle cargo.

[0005] SUMMARY OF THE PRESENT EMBODIMENT The present invention has been made in consideration of the above problems, and one of its objects is to provide a transport aid that can be conveniently used when performing loading and unloading work with a forklift. [Means for solving the problem]

[0006] The transportation aid according to one embodiment of the present invention includes a plate-shaped member placed on a cart, and a square piece of material arranged on the upper surface of the plate-shaped member at a distance and extending in one direction. The side surface of the plate-shaped member is preferably colored. The plate-shaped member is preferably transparent.

[0007] In one embodiment of the present invention, the lower surface of the plate-like member may be provided with a positioning member for positioning the plate-like member at the center of the platform of the dolly. The outer end of the plate-like member may be provided with a stopper for preventing a load placed on the plate-like member from protruding. The upper surface of the plate-like member may be provided with a second rectangular timber extending in a direction intersecting the one direction, outside the at least two rectangular timbers. Effect of the Invention

[0008] The transport aid of the present invention has a plate-shaped member and a square timber, and a colored portion is provided at the end of the plate-shaped member. Therefore, when performing loading and unloading operations using a forklift, the colored portion can be used as a marker to place luggage in line with the center of gravity of the cart.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different aspects, and should not be interpreted as being limited to the description of the embodiments exemplified below. In the drawings, the width, thickness, shape, etc. of each part may be shown schematically compared to the actual aspect in order to make the explanation clearer, but it is merely an example and does not limit the interpretation of the present invention. In this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals (or reference numerals with a, b, etc. added after the numerals) and detailed explanations may be omitted as appropriate. Furthermore, the letters "first" and "second" added to each element are convenient marks used to distinguish each element, and have no further meaning unless otherwise explained.

[0011] [First embodiment] 1(A) to (C) show a transportation aid 100 according to this embodiment, where (A) is a plan view, (B) is a front view, and (C) is a side view. The transportation aid 100 according to this embodiment can be suitably used when performing loading and unloading work using a forklift.

[0012] The transport aid 100 includes a plate-shaped member 102 and at least a block 104. The plate-shaped member 102 is a flat member having a rectangular shape in a plan view. The block 104 is a rectangular bar-shaped member, and two of them are arranged apart from each other on the upper surface of the plate-shaped member 102. For example, the two blocks 104 are arranged side by side so as to be approximately parallel to the short side of the plate-shaped member 102. The two blocks 104 are arranged with a gap between them that allows the forks of a forklift to be inserted. The two blocks 104 are also arranged so that their positions are approximately equal in the front-rear and left-right directions within the plane of the plate-shaped member 102.

[0013] The beams 104 may simply be placed on the top surface of the plate-like member 102, or may be fixed with adhesive or fasteners (screws, bolts, etc.). When the beams 104 are not fixed to the plate-like member 102, the spacing between them can be adjusted as appropriate, which is convenient for loading and unloading operations. When the beams 104 are fixed to the plate-like member 102, the position of the beams 104 can be stably maintained, which improves the workability of loading and unloading operations.

[0014] The transportation aid 100 is used by being placed on a cart 200. The cart 200 has a platform 202 and casters 204, and is configured to be movable on a floor surface by human power or an automatic guided vehicle 300 (AGV: Automatic Guided Vehicle). The casters 204 are preferably provided at four positions on the platform 202, thereby allowing the transportation aid 100 to move freely in all directions, forward and backward, left and right, and diagonally. The transportation aid 100 placed on the cart 200 is arranged so that the underside of the plate-like member 102 is in contact with the platform 202 and the beam 104 is exposed above the platform 202. As shown in FIGS. 1(B) and (C), the cargo 400 to be transported is placed on the beam 104.

[0015] The size of the transportation aid 100 can be appropriately selected depending on the luggage to be transported, but it is preferable that the end of the plate-shaped member 102 is large enough to be positioned outside the loading platform 202 of the dolly 200 along the entire circumference. The plate-shaped member 102 preferably has the same size as the luggage 400 to be transported in a plan view. Also, the plate-shaped member 102 may be larger than the luggage 400 to be transported in a plan view. By making the plate-shaped member 102 of the transportation aid 100 have such a size, when performing loading and unloading work with a forklift, the operator can visually check the edge (end) of the plate-shaped member 102 and place the outer end of the luggage 400 in line with the edge (end) of the plate-shaped member 102.

[0016] The side surface (edge) of the plate-like member 102 may have a colored portion 106 that is colored to improve visibility. The coloring applied to the colored portion 106 is preferably a bright color among chromatic colors, for example, yellow, orange, green, etc. The coloring applied to the colored portion 106 may be a bright fluorescent color, or any design or pattern may be expressed by combining such a chromatic color with an achromatic color (chestnut, gray, white). The colored portion 106 may be colored with paint such as paint, or a colored adhesive tape may be attached. Although not shown, a light-emitting diode may be provided on the side surface (edge) of the plate-like member 102, thereby forming the colored portion 106.

[0017] The plate-like member 102 may be made of a transparent material. For example, the plate-like member 102 is preferably made of a transparent plastic such as acrylic, polyethylene terephthalate, or polycarbonate. The plate-like member 102 being transparent can increase the contrast with the colored portion 106 formed on the side (edge) and improve visibility. In addition, when the transportation aid 100 is placed on the dolly 200, it can be visually confirmed that the center of gravity is located at the center of the loading platform 202. Furthermore, the plate-like member 102 is made of a lightweight material such as plastic, so that the transportation aid 100 can be made lighter, reducing the labor required and improving workability.

[0018] Figures 2(A) to (C) show a series of cargo handling operations. Figure 2(A) shows the stage where a forklift 402 transports a load 400 to the position of the dolly 200. The transportation aid 100 is set in advance on the dolly 200. There is no limitation on the type of load 400 transported by the forklift 402, but Figures 2(A) to (C) show the case where the load 400 is a gypsum board.

[0019] FIG. 2(B) shows the stage of placing the luggage 400 on the dolly 200. The operator must carefully operate the forklift 402 so that the center of gravity of the luggage 400 is aligned with the center of the dolly 200. At this time, the luggage 400 is lifted to a predetermined height by the forks, and the operator cannot directly see the entire dolly 200, but can see the edge of the transportation aid 100. The colored portion 106 is provided on the edge of the transportation aid 100 according to this embodiment to improve visibility. Therefore, the operator can place the luggage 400 on the dolly 200 (more precisely, on the transportation aid 100) using the colored portion 106 as a marker.

[0020] Specifically, the operator operates the forklift 402 so that when adjusting the position in the front-rear direction, the front side W1 of the luggage 400 is aligned with the front side W2 of the transportation aid 100, and when adjusting the position in the left-right direction, the operator aligns the side D1 of the luggage 400 with the side D2 of the transportation aid 100. The colored portion 106 is provided at the end (edge) of the plate-like member 102 of the transportation aid 100, improving visibility. Since the size of the plate-like member 102 in a plan view is the same as that of the luggage 400, the luggage 400 can be unloaded by placing the luggage 400 using the colored portion 106 as a marker, in line with the center of gravity of the cart 200.

[0021] 2(C) shows the state in which the cargo 400 has been placed on the cart 200 in this manner. In reality, the cargo 400 is placed on top of the timbers 104 that are arranged side by side. Because the spacing between the timbers 104 is wider than the width of the forks, the forklift 402 that has lowered the cargo 400 can move backwards and away from the cart 200. The cargo 400 placed on the timbers 104 is placed in accordance with the center of gravity of the cart 200, so the cargo 400 remains stable even when it is separated from the forklift 402 without collapsing.

[0022] 2(B) has been described as an example in which the size of the plate-like member 102 is the same as the size of the luggage 400 in a plan view, but the plate-like member 102 may be larger than the luggage 400 and its end may protrude outward. When the end of the plate-like member 102 is on the outside of the luggage 400, the operator can visually check the end of the plate-like member 102 and can therefore unload the luggage 400 by assuming the center of gravity of the cart 200 based on the end.

[0023] As described above, the transportation aid 100 according to this embodiment has the plate-like member 102 and the square timber 104, and the colored portion 106 is provided on the end (edge) of the plate-like member 102, so that the baggage 400 can be placed using the colored portion 106 as a marker. By setting such a transportation aid 100 on the dolly 200, the baggage 400 can be placed in accordance with the center of gravity of the dolly 200. In this case, since the plate-like member 102 is transparent, the transportation aid 100 can be set in accordance with the center of the dolly 200. Furthermore, since the plate-like member 102 is made of a lightweight material, the labor required can be reduced and workability can be improved.

[0024] [Second embodiment] 3(A) to (C) show the carrying aid 100 according to this embodiment, where (A) is a plan view, (B) is a front view, and (C) is a side view. In the following explanation, the differences from the first embodiment will be mainly described, and explanations of overlapping parts will be omitted as appropriate.

[0025] The transportation aid 100 according to this embodiment has a positioning member 108 for setting the plate-shaped member 102 in alignment with the center of the cart 200. The positioning member 108 is provided on the underside of the plate-shaped member 102. The positioning member 108 is made of a plate material, and is formed in a shape that protrudes outward so as to contact the side surface of the loading platform 202 of the cart 200. The positioning member 108 can be considered a guide plate that abuts against the side surface of the loading platform 202.

[0026] There is no limitation on the arrangement of the positioning member 108, so long as it is in a position where it abuts against the side surface of the loading platform 202. Furthermore, there is no limitation on the shape of the positioning member 108, so long as it has the function of a guide plate. For example, as shown in FIG. 3(A), the positioning member 108 may have a hook shape so as to abut against a corner of the loading platform 202 in a plan view. The positioning member 108 having such a shape may be provided at least in one place on the lower surface of the plate-like member 102, and preferably in multiple places. For example, as shown in FIG. 3(A), it may be provided in four places corresponding to the corners of the loading platform 202.

[0027] 4(A) to (C) show an example in which the positioning member 108 is formed of a protruding member protruding from the lower surface of the plate-like member 102. Here, FIG. 4(A) shows a plan view, (B) shows a front view, and (C) shows a side view. When a single pipe hole is provided in the loading platform 202 of the dolly 200, a protruding member can be provided to fit into the single pipe hole 206 and used as the positioning member 108. The protruding member as the positioning member 108 may be provided at least in one place on the lower surface of the plate-like member 102 in accordance with the arrangement of the single pipe hole 206, and preferably in multiple places. For example, as shown in FIG. 3(A), it may be provided in four places corresponding to the corners of the loading platform 202.

[0028] According to this embodiment, the transportation aid 100 is provided with a positioning member 108, so that the plate member 102 can be easily set so as to align with the center of the cart 200. The transportation aid 100 according to this embodiment is similar to that in the first embodiment except for the provision of the positioning member 108, and can achieve the same effects.

[0029] [Third embodiment] 5(A) to (C) show the carrying aid 100 according to this embodiment, where (A) is a plan view, (B) is a front view, and (C) is a side view. In the following explanation, the differences from the first embodiment will be mainly described, and explanations of overlapping parts will be omitted as appropriate.

[0030] The transportation aid 100 according to this embodiment has a structure in which a stopper 110 is provided on a plate-like member 102. The stopper 110 is disposed on the end of the plate-like member 102 and is provided so as to protrude upward. The shape of the stopper 110 is arbitrary, and it is formed from a plate or a bar. The stopper 110 is used for positioning the luggage 400 when it is placed on the block 104.

[0031] The stopper 110 may be disposed in any position as long as it does not prevent the load 400 from being placed horizontally on the beam 104. The stopper 110 may be disposed in any position as long as it allows the load 400 to be accurately positioned. For example, as shown in FIG. 5(A), the stopper 110 may have a hook shape in a plan view and be provided in correspondence with a corner of the plate member 102. Such a stopper 110 may be provided at least in one place so as to protrude upward from the plate member 102, and preferably in multiple places. For example, as shown in FIG. 5(A), the stopper 110 may be provided in four places corresponding to the corners of the plate member 102. When the load 400 is placed on the beam 104, the load 400 may be placed inside the stopper 110. By providing the stopper 110 on the plate member 102, the load 400 can be accurately placed on the transport aid 100 without causing positional deviation in the front-rear and left-right directions.

[0032] 6(A) to (C) show an example in which the stopper 110 is disposed on one side of the plate-shaped member 102. Here, FIG. 6(A) shows a plan view, (B) shows a front view, and (C) shows a side view. When the stopper 110 is disposed on one side of the plate-shaped member 102, the position of the luggage 400 may be adjusted so as to move to one side. Since the size of the plate-shaped member 102 in a plan view is the same as that of the luggage 400, the luggage 400 can be accurately placed on the transportation aid 100 in this manner as well. In addition, by making the stopper 110 on the front side when carrying in the luggage 400 flat rather than hook-shaped and not providing a stopper on the front side of the plate-shaped member 102, it is possible to easily adjust the front and rear when unloading the luggage 400.

[0033] According to this embodiment, the transportation aid 100 is provided with a stopper 110, so that the luggage 400 can be lowered so as to be aligned with the center of the plate-like member 102. The transportation aid 100 according to this embodiment is similar to that of the first embodiment except for the stopper 110, and can achieve the same effects. The transportation aid 100 according to this embodiment can be appropriately combined with the configuration according to the second embodiment.

[0034] [Fourth embodiment] 7(A) to (C) show the carrying aid 100 according to this embodiment, where (A) is a plan view, (B) is a front view, and (C) is a side view. In the following explanation, the differences from the first embodiment will be mainly described, and explanations of overlapping parts will be omitted as appropriate.

[0035] The carrying aid 100 according to this embodiment has a configuration in which, in addition to the square beam 104 arranged in a direction parallel to the short side of the plate-like member 102, a second square beam 112 is added to the outside of the square beam 104. The second square beam 112 is arranged so as to extend in a direction parallel to the long side of the plate-like member 102. In other words, the second square beam 112 is arranged so as to extend in a direction intersecting the longitudinal direction of the square beam 104.

[0036] In this way, by adding the second beam 112 onto the plate-like member 102, the luggage can be transported in a more stable state when using the dolly 200. The transportation aid 100 according to this embodiment is similar to that of the first embodiment except for the provision of the second beam 112, and can achieve the same effects. The transportation aid 100 according to this embodiment can be appropriately combined with the configurations according to the second and third embodiments. [Explanation of symbols]
