  Hereinafter, a luggage transfer system 10 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an entire configuration of a luggage reloading system 10 and a forklift 11 that transports luggage P to be reloaded on a pallet 50 using the system 10. FIG. 2 is an enlarged view showing the entire configuration of the luggage changing jig 20 included in the luggage changing system 10 and a partial configuration included therein. FIG. 3 is an enlarged view of the configuration of the retaining mechanism 30 included in the luggage changing jig 20 when viewed from above and a part of the configuration included therein.

  As shown in FIGS. 1 to 3, the luggage transfer system 10 includes four luggage transfer jigs 20-1 to 20-4 and the jigs 20-1 to 20-4 installed in the vicinity of each corner. And a pallet 50 to be used. Since the luggage reloading jigs 20-1 to 20-4 have substantially the same configuration, the following description mainly describes the luggage reloading jig 20-1. Description of the jigs 20-2 to 20-4 will be omitted as appropriate. Further, in the following description, when there is no need to distinguish the luggage changing jig 20-1 from the other luggage changing jigs 20-2 to 20-4, hyphens and below are omitted and “luggage” is omitted. This is described as “replacement jig 20”. 2 to 6C other than FIG. 1 are similarly described as “luggage changing jig 20”.

  As shown in FIG. 1, the luggage transfer jig 20 temporarily transfers the luggage P on the pallet 50 when the luggage P placed on the two transport claws 11 a and 11 b provided on the forklift 11 is replaced. With such a structure, the pawls 11a and 11b can be smoothly pulled out from between the pallet 50 and the load P. In the present embodiment, the case where the load P is replaced on the pallet 50 by using the forklift 11 is taken as an example. However, other transport means such as a hand lift having claws for transporting the load may be used.

  As shown in FIGS. 2 and 3, the luggage changing jig 20 includes a support rod 22 having a substantially square cross section. Flanges 22a and 22b are attached to both upper and lower ends of the support rod 22, respectively. The upper end side flange 22a has a substantially quadrangular outer shape in a plan view, and is formed in a size that can be inserted into the pallet 50 from a gap between boards in the pallet 50 described later. Functions as a stopper to prevent falling off. The lower flange 22b has substantially the same configuration as the upper flange 22a. The upper surface of the flange 22a has a role as a support surface 22a-1 for supporting the load, and the lower surface of the flange 22b has a role as a ground surface 22b-1.

  Further, it is preferable that the luggage changing jig 20 is provided with a detachable mechanism 30 that is movably attached to the support bar 22 and that prevents the support bar 22 from dropping off the pallet 50. The detachment prevention mechanism 30 includes a slide body 32 movably inserted into the support rod 22. The slide body 32 is a tubular member having a substantially square external shape when viewed from above, and has a pair of detachable arms 34 and 36 rotatably attached thereto. Since the configurations of the retaining arms 34 and 36 are the same, the retaining arm 34 will be described below, and the description of the retaining arm 36 will be omitted as appropriate.

  As shown in FIGS. 2 and 3, the retaining arm 34 is a substantially trapezoidal plate-like member in a plan view in which the outer end 34 a is wider than the inner end 34 b. Here, the width at the outer end 34a is W1, and the length of the locking mechanism 30 in the direction in which the locking arms 34, 36 protrude from the slide body 32 (in other words, the direction orthogonal to the support bar 22) is T1. . Further, the retaining arm 34 is rotatable within a range of about 90 ° from a position shown by a solid line in FIG. 2 orthogonal to the longitudinal direction of the support bar 22 to a position parallel to the longitudinal direction of the support bar 22 shown by a broken line in FIG. Are attached to the slide body 32 via hinges (rotation support portions) 35a and 35b. Since the configuration of both hinges 35a and 35b is the same, only the hinge 35a will be described below.

  An elastic spring (biasing means) 35a-1 is attached to the hinge 35a, and the retaining arm 34 is rotated by the elastic force of the elastic spring 35a-1 in a direction orthogonal to the longitudinal direction of the support rod 22. Be inspired. Further, resin-made elastic plates 37a and 37b may be provided on the end surface 32b of the slide body 32 on the grounding surface 22b-1 side. Here, since the elastic plates 37a and 37b have the same configuration, only the elastic plate 37a will be described, and the description of the elastic plate 37b will be omitted. The elastic plate 37a extends outside the end surface 32b of the slide body 32, and is depressed by the inner end 34b of the arm 34 when the retaining arm 34 rotates upward to bend downward. Accordingly, the arm 34 is urged to rotate toward the ground contact surface 22b-1, that is, downward.

  As shown in FIGS. 2 and 3, the extension arm 40 may be attached to the retaining arm 34. The extension arm 40 has a substantially trapezoidal shape in plan view, and is a plate-shaped member formed so that the outer end 45 is wider than the connection-side end 44. Male hooks 38a and 38b functioning as fasteners are provided at the outer end 34a of the retaining arm 34. Female hooks 42a and 42b that can be attached to and detached from the male hooks 38a and 38b are extended arms 40. Is provided at the connection-side end portion 44. In addition, a cover plate 46a, 46b, 46c, 46d made of resin is attached to the connection end 44 of the extension arm 40 so as to surround the end surface 44-1.

  Then, by inserting the outer end 34a of the retaining arm 34 into the space surrounded by the cover plates 46a to 46d, the female hooks 42a and 42b fit into the male hooks 38a and 38b of the retaining arm 34. Fixed. If the gaps between the boards 54a, 54b, 54c,..., 56a, 56b, 56c... Constituting the pallet 50 are large, the extension arm 40 is attached to increase the length of the arm of the retaining arm 34. It is possible to do. By attaching an extension arm having the same configuration as that of the extension arm 40, it is possible to increase the length of the arm of the opposite retaining arm 36.

  As shown in FIG. 1, the pallet 50 is a wooden double-sided pallet, and has boards 54a, 54b, 54c,..., 56a, above and below three parallel beams 52a, 52b, 52c. .. Are arranged at equal intervals to form the loading surfaces 50-1 and 50-2 and the insertion portions 58-1 and 58-2 for inserting the claws 11a and 11b of the forklift 11, respectively. . The size of the gap between the boards 54a and 54b is formed to be larger than the width W1 of the above-described stopper arm 34 and smaller than the length T1 in the protruding direction. In this embodiment, the pallet 50 is an example of a double-sided pallet. However, a single-sided pallet or another type of pallet may be used as long as the pallet on which the jig 20 can be installed. It may be. Further, the pallet 50 is not limited to a wooden pallet, and may be made of a resin or another material.

  Next, a method of transshipping luggage using the luggage transfer system 10 will be described with reference to FIGS. First, a procedure for installing the luggage changing jig 20 on the pallet 50 will be described with reference to FIGS. 4 (a) to 4 (c). As shown in FIG. 4A, with the pallet 50 placed on the ground, the luggage transfer jig 20 is inserted through the gap between the boards 54a and 54b on the upper surface side.

  At this time, as shown in FIG. 4 (b), when the retaining arm 34 comes into contact with the boards 54a, 54b on both sides, each of them rotates upward, and the jig 20 for reloading the luggage is inserted from the gap between the boards 54a, 54b. Becomes possible. Then, as shown in FIG. 4 (c), the grounding surface 22b-1 of the support rod 22 is grounded to the ground, so that the retaining arms 34, 36 respectively overlap with the upper surfaces of the lower boards 56a, 56b. Become. By installing the other luggage changing jigs 20 on the pallet 50 in the same procedure, the work of installing the luggage changing jig 20 on the pallet 50 is completed.

  Next, a procedure for pulling out the claws 11a and 11b of the forklift 11 will be described with reference to FIGS. As shown in FIG. 5A, since the luggage changing jig 20 is attached to each corner of the pallet 50, when the luggage P is to be lowered onto the pallet 50 using the forklift 11, the luggage P is loaded. The support jig 20 is supported by each support surface 22a-1. Here, the length of the support rod 22 in the luggage transfer jig 20 in the longitudinal direction (that is, the dimension between the flanges 22a and 22b) is, as shown in FIG. 5A, the support surface 22a of the support rod 22. The distance L between the pallet 50 and the loading surface 50-1 of the pallet 50 is set in advance so that the claws 11a and 11b can be inserted and removed.

  Therefore, the claw 11a, 11b of the forklift 11 is slightly lowered from the state shown in FIG. 5A as shown in FIG. The claws 11a and 11b can be pulled out from between P and the loading surface 50-1 of the pallet 50.

  Then, by inserting the claws 11a and 11b of the forklift 11 into the insertion portions 58-1 (see FIG. 1) and 58-2 of the pallet 50 as shown in FIG. Lift the pallet 50 together with P.

  At this time, since the retaining arms 34 and 36 are respectively mounted on the boards 56a and 56b on the lower surface side, the slide body 32 to which the arms 34 and 36 are attached slides relatively upward with respect to the support rod 22. I do. As shown in FIG. 6B, when the slide body 32 comes into contact with the upper flange 22a of the support rod 22, the retaining arms 34, 36 are hooked on the lower boards 56a, 56b, so that the luggage can be reloaded. The jig 20 is hung on the pallet 50. In this state, by pulling the support bar 22 of the luggage changing jig 20 downward, the luggage changing jig 20 can be pulled out from the pallet 50 and collected as shown in FIG.

  In the present embodiment, an example is described in which the luggage changing jig 20 includes the slip-off preventing mechanism 30. However, the luggage changing jig 20 does not include the slip-off preventing mechanism 30, that is, only the support rod 22 is used. It may be done. However, in this case, when the pallet 50 is lifted by the pawls 11a and 11b of the forklift 11, the jig 20 for dropping the load falls off the pallet 50 as shown in FIGS. 6A and 6B. Therefore, it is more preferable to provide the stopper mechanism 30 as in the present embodiment.

  As described above, the retaining arms 34 and 36 have a substantially trapezoidal outer shape in plan view (see FIG. 2). For this reason, even if the pallet 50 is shaken in a state where the luggage changing jig 20 is hung, the luggage changing jig 20 is more likely to be formed than in a case where the retaining arm is formed of a substantially rectangular plate material in plan view. It becomes difficult to fall down.

  Therefore, it is possible to prevent the luggage changing jig 20 from falling down and falling off the pallet 50 due to the swing of the pallet 50. Therefore, when the pallet 50 is transported by the forklift 11 or the like in a state where the luggage changing jig 20 is hung on the pallet 50, there is an advantage that the luggage changing jig 20 does not easily fall off the pallet 50.

  By retrieving other luggage changing jigs 20 in the same procedure as the luggage changing jig 20, the operation of changing the luggage P onto the pallet 50 is completed.

  According to the luggage reloading system 10 of the present embodiment, the luggage P is supported on the support surface in a state where the support rods 22 of the luggage reloading jigs 20 are inserted through the gaps between the boards 54a, 54b, 54c,. By being placed on 22a-1, a gap for pulling out the claws 11a and 11b can be formed between the load P and the pallet 50. Thereby, the claws 11a and 11b of the forklift 11 can be easily pulled out from between the baggage P and the pallet 50, and the labor for pulling out can be reduced.

  In the above embodiment, the example in which the luggage changing jig 20 is inserted into the pallet 50 from the gap between the upper boards 54a and 54b, but the luggage changing jig 20 is connected to the lower boards 56a and 56b. May be inserted into the pallet 50 and installed. In this case, the pallet 50 may be lifted in advance by using a forklift 11 or the like, and the jig 20 for reloading the luggage may be inserted so that the flange 22b faces upward from the gap between the lower boards 56a and 56b. Also, by lowering the pallet 50 on the ground, the flange 22b protrudes from the gap between the boards 54a, 54b on the upper surface side. Therefore, it is possible to pull out the luggage transfer jig 20 from the inside of the pallet 50 by lifting the flange 22b. It is.

  In the above-described embodiment, an example in which the luggage changing jigs 20 are arranged at the respective corners of the pallet 50, that is, four luggage changing jigs 20 are used, but the size of the luggage, The number of the jigs may be appropriately adjusted according to the packing style and weight.

  Next, a modified example of the luggage changing jig 20 in the luggage changing system 10 of the embodiment will be described with reference to FIGS. 7 (a-1) to 7 (c). In the following description, portions common to the configuration of the luggage changing jig 20 in the above embodiment will be denoted by the same reference numerals as appropriate, will not be described, and description thereof will be omitted. Only different portions of the configuration will be described. I do.

  As shown in FIGS. 7A-1 and 7A-2, the luggage changing jig 120 includes a detachment preventing mechanism 130 instead of the detaching stopper mechanism 30 in the above embodiment. The retaining mechanism 130 includes the slide body 32 and the retaining arms 134 and 136 fixedly supported at the lower end of the slide body 32. Since the structures of the retaining arms 134 and 136 are the same, only the retaining arm 134 will be described, and the description of the retaining arm 136 will be omitted as appropriate.

  The retaining arm 134 is a plate-like member having a substantially rectangular shape in a plan view, and the width W2 of the retaining arm 134 is set to the side surface 32a as the mounting surface of the slide body 32, as shown in FIG. It is set to the same length as the width of. Further, the width W2 of the retaining arm 134 is set to be shorter than the size of the gap between the boards 54a and 54b constituting the pallet 50.

  On the other hand, the length T2 of the retaining mechanism 130 in the direction in which the retaining arms 134 and 136 protrude from the slide body 32 is set to be larger than the gap between the boards 54a and 54b constituting the pallet 50. Therefore, if the retaining mechanism 130 is held so that the direction in which the retaining arms 134 and 136 protrude is substantially parallel to the longitudinal direction of the boards 54a and 54b, the load can be loaded into the pallet 50 from the gap between the boards 54a and 54b. The replacement jig 120 can be inserted.

  Next, a procedure for installing the luggage changing jig 120 on the pallet 50 will be described with reference to FIGS. 7B and 7C. As shown in FIG. 7 (b), in a state in which the projections of the retaining arms 134, 136 of the retaining mechanism 130 are held substantially parallel to the longitudinal direction of the boards 54a, 54b, the gaps between the boards 54a, 54b are maintained. The jig 120 for loading luggage is inserted into the pallet 50. The luggage changing jig 120 is inserted into the inside of the pallet 50, and then the luggage changing jig 120 is rotated by 90 ° about the axis of the support rod 22 as shown in FIG. , 136 can be grounded in a state where the distal ends of the support bars 22 are hooked on the lower boards 56a, 56b.

  Further, in a state where the pallet 50 is lifted by the claws 11a and 11b of the forklift 11 similarly to the case shown in FIG. The pallet 50 may be rotated and removed from the space between the boards 56a and 56b on the lower surface side of the pallet 50 for collection.

  In this modification, the jig for loading and reloading the pallet 50 from the gap between the boards 54a and 54b is held in such a manner that the protruding directions of the retaining arms 134 and 136 are substantially parallel to the longitudinal directions of the boards 54a and 54b. An example is shown in which the H.120 can be inserted. Similarly, by holding the retaining arms 34, 36, the luggage changing jig 20 in the above embodiment is inserted into the pallet 50 from the gap between the boards 54a, 54b or the gap between the boards 56a, 56b, or The pallet 50 may be pulled out from the inside.

  In this way, even when the jig 120 for reloading luggage is installed on the pallet 50, the same effect as the jig 20 for reloading luggage in the above embodiment can be obtained.

  The present invention can also be implemented in modes in which various improvements, modifications, or variations are made based on the knowledge of those skilled in the art without departing from the spirit thereof. In addition, any technique may be replaced with another technique within a range in which the same operation or effect is generated.
