[0008] [First embodiment] 1 to 9 show an attachment 10 according to a first embodiment. As shown in Fig. 1, the attachment 10 is attached to a pallet 100 as a "carrier" while holding a wireless communication device 90 (see Fig. 5; for example, a passive RF tag).

[0009] The pallet 100 has an upper deck board 101 and a lower deck board 102 that are rectangular in plan view, and side walls 103 and girders 104, 105 that connect the upper and lower deck boards 101, 102 to each other. The side walls 103 connect the short sides of the upper and lower deck boards 101, 102 to each other. The girders 104, 105 include an intermediate girder 104 that connects the middle portions of the long sides of the upper and lower deck boards 101, 102 to each other, and a central girder 105 (see FIG. 3) that connects the central portions of the upper and lower deck boards 101, 102 to each other. A fork insertion space 106 is defined between the side walls 103 and the girders 104, 105. Furthermore, the pallet 100 of this embodiment is a welded pallet in which two injection-molded articles 100A of the same shape are welded together facing each other up and down, and can be used even if turned upside down.

[0010] 1 and 2, a through-hole 110 for accommodating a wireless communication device 90 is formed in the center of the pallet 100. In detail, a rectangular tube portion 111 having a substantially square cross section is formed in the center of a central beam portion 105 (see FIG. 3) of the pallet 100, and the inside of this is the through-hole 110. Each side of the opening of the through-hole 110 is inclined at 45 degrees with respect to each side of the pallet 100.

[0011] 2 and 3, the through hole 110 is provided with a plurality of engaging ridges 112, 113 that protrude inward from the inner surface. The engaging ridges 112, 113 include upper engaging ridges 112 arranged near the upper end opening of the through hole 110 and lower engaging ridges 113 arranged near the lower end opening, with one engaging ridge 112 arranged on each of the four tube-constituting walls 111A that make up the rectangular tube portion 111. When each tube-constituting wall 111A is placed forward, each upper engaging ridge 112 extends from the left end to a position forward from the horizontal center, and the group of upper engaging ridges 112 is rotationally symmetrical, overlapping when rotated 90° around the central axis of the through hole 110. When each cylinder-constituting wall 111A is placed in front, each lower engaging ridge 113 extends from the right end to a position in front of the horizontal center, and the group of lower engaging ridges 113 is also rotationally symmetric, overlapping when rotated by 90° around the central axis of the through-hole 110. As a result, the group of upper engaging ridges 112 and the group of lower engaging ridges 113 do not face each other vertically, but are arranged to overlap each other when the pallet 100 is turned upside down.

[0012] Each engaging protrusion 112, 113 has a guide surface 112A, 113A on the opening end side of the through hole 110 and a locking surface 112B, 113B on the inside of the through hole 110. The guide surfaces 112A, 113A are inclined inward in the axial direction of the through hole 110 as they move away from the tube-constituting wall 111A. The locking surfaces 112B, 113B are perpendicular to the tube-constituting wall 111A. In the rectangular tube portion 111, the inner surfaces of the engaging protrusions 112, 113 closer to the opening end than the locking surfaces 112B, 113B are tapered so that the opening becomes smaller as it moves inward in the axial direction. The opening in the axial direction of the rectangular tube portion 111 is larger in a stepped manner in the portion inward from the locking surfaces 112B, 113B than the portion closer to the opening end than the locking surfaces 112B, 113B (see FIG. 7).

[0013] FIG. 5 shows a communication device holder 91 for holding a wireless communication device 90. The wireless communication device 90 is rectangular, and the communication device holder 91 has a frame portion 92 that surrounds the wireless communication device 90 and whose longitudinal direction is parallel to the vertical direction. The frame portion 92 has a strip-shaped upper end wall 93, a pair of frame side portions 94 that hang down from positions near both ends of the upper end wall 93, and a frame lower portion 95 that connects the lower ends of the frame side portions 94. The frame lower portion 95 has an inclined portion 95A that extends downward from the lower end of each frame side portion 94 and a horizontal portion 95B that extends parallel to the upper end wall 93 and connects the lower ends of the inclined portions 95A. The width of the frame side portions 94 is smaller than the width of the upper end wall 93, and the upper end wall 93 protrudes laterally beyond the frame side portions 94 in both the longitudinal and lateral directions.

[0014] A locking projection 94A is formed on the outer surface of the frame side portion 94. The upper surface of the locking projection 94A forms a locking surface 94B that is perpendicular to the frame side portion 94, and the portion of the side surface of the locking projection 94A below a position near the upper end forms a guide surface 94C that is inclined so as to approach the outer surface of the frame side portion 94 as it progresses downward. In addition, a notch 93A is formed in the center of one long side of the upper end wall 93.

[0015] As shown in FIG. 4, the communication device holder 91 is provided with a support portion 97 at one end of the frame portion 92 in the thickness direction, which faces one surface of the wireless communication device 90. The support portion 97 has multiple ribs 97B, 97C extending vertically and horizontally. Specifically, the support portion 97 has three horizontal ribs 97B connecting the pair of frame side portions 94, two vertical ribs 97C connecting the upper end wall 93 and the lower horizontal rib 97B, and multiple auxiliary ribs 97D. As shown in FIG. 5, a connecting wall 97R hangs down from the other end of the lower horizontal rib 97B in the thickness direction of the frame portion 92 to the frame lower portion 95, and a protrusion 97T extending horizontally is provided near the lower end of the connecting wall 97R.

[0016] 5, the communication device holder 91 is provided with support pieces 96 at the other end in the thickness direction of the frame portion 92, which protrude toward each other from a pair of frame side portions 94. The support pieces 96 are rectangular in shape and are elongated in the vertical direction, and three support pieces 96 are arranged vertically on each frame side portion 94. Each support piece 96 faces three spaces (six spaces in total) defined by horizontal ribs 97B within the space between the vertical rib 97C of the support portion 97 and the frame side portion 94.

[0017] The wireless communication device 90 accommodated in the communication device holder 91 is prevented from slipping out in the plate thickness direction by the support portions 97 and support pieces 96, and is prevented from slipping out in the up-down direction by the protrusions 97T and the upper end wall 93. The wireless communication device 90 may be attached by inserting one widthwise edge behind the support pieces 96 on one frame side 94, bending it in the widthwise direction, and then inserting it behind the support piece 96 on the opposite side, or by inserting one longitudinal end behind the pair of support pieces 96 at the lower end and sliding it toward the upper end wall 93.

[0018] 3, the attachment 10 holding the communication device holder 91 is attached to the upper opening of the through-hole 110, and only the attachment 10 is attached to the lower opening of the through-hole 110. Next, the attachment 10 will be described in detail.

[0019] As shown in FIG. 6, the attachment 10 has an attachment body 11 that fits inside the open end of a through-hole 110 (see FIG. 2A), and multiple engagement pieces 30, 40 that protrude from multiple positions on the attachment body 11. The attachment body 11 has a substantially square main plate portion 12 that corresponds to the open end of the through-hole 110, and a hanging wall portion 13 that hangs down from the outer edge of the main plate portion 12. A holder fitting portion 14 that extends like an elongated hole along one side of the main plate portion 12 is formed through the main plate portion 12. Hereinafter, the direction in which the holder fitting portion 14 extends is referred to as a first direction H1, and the direction perpendicular to the first direction H1 is referred to as a second direction H2. The holder fitting portion 14 is disposed in the center of the second direction H2.

[0020] The holder fitting portion 14 has a rectangular planar shape corresponding to the upper end wall 93 of the communicator holder 91, and an upward-facing stepped surface 14A is provided at the vertical center of the opening edge. As a result, the opening above the stepped surface 14A in the holder fitting portion 14 is larger than the opening below. When the communicator holder 91 is inserted into the holder fitting portion 14 from above, the portion of the frame portion 92 below the upper end wall 93 fits into the holder fitting portion 14, and the outer edge of the upper end wall 93 abuts against the stepped surface 14A (see FIGS. 7 and 8).

[0021] 7, when the upper end wall 93 is in contact with the stepped surface 14A, the locking surface 94B of the locking projection 94A of the communication device holder 91 faces from below the opening edge of the holder fitting portion 14. As a result, the portion of the opening edge of the holder fitting portion 14 below the stepped surface 14A is sandwiched between the upper end wall 93 and the locking projection 94A, preventing the end of the communication device holder 91 from slipping out of the holder fitting portion 14, and holding the communication device holder 91 in a cantilevered state on the holder fitting portion 14.

[0022] In addition, a guide surface 94C is formed on the locking protrusion 94A opposite the locking surface 94B, so when the communication device holder 91 is inserted into the holder fitting portion 14, this guide surface 94C rubs against the portion of the opening edge of the holder fitting portion 14 below the step surface 14A, making it easier to elastically deform the frame side portion 94 of the communication device holder 91, and allowing the communication device holder 91 to be inserted smoothly.

[0023] Furthermore, when the communication device holder 91 is attached to the attachment 10, the upper end wall 93 is received above the step surface 14A of the holder fitting portion 14, and the upper surface of the upper end wall 93 is positioned slightly below the upper surface of the attachment main body 11 so as not to protrude from the upper surface of the attachment main body 11.

[0024] When removing the communication device holder 91 from the attachment 10, a tool is inserted into the notch 93A of the communication device holder 91 and pushed up, so that the locking protrusion 94A passes over the opening edge of the holder fitting portion 14 and is removed.

[0025] As shown in Fig. 6A, drainage holes 15 are formed through the main plate portion 12 of the attachment body 11 on both sides of the holder fitting portion 14. The drainage holes 15 are elongated holes that extend along the holder fitting portion 14 and are shorter in length than the holder fitting portion 14. In Fig. 6A, of the two drainage holes 15, the left drainage hole 15 is located closer to the front in the first direction H1, and the right drainage hole 15 is located closer to the back in the first direction H1.

[0026] Furthermore, a plurality of notches 16, 17 are formed on the outer edge of the attachment body 11. Specifically, first notches 16 are formed on opposing sides of the attachment body 11 that face each other in the first direction H1, and second notches 17 are formed on opposing sides that face each other in the second direction H2. The first notch 16 on the front side in the first direction H1 is provided in a range from a position facing the right end of the holder fitting portion 14 to the right end of the attachment body 11, and the first notch 16 on the back side is provided in a range from a position facing the left end of the holder fitting portion 14 to the left end of the attachment body 11.

[0027] The left second cutout 17 is arranged in an intermediate position closer to the front than the center in the first direction H1 of one side of the attachment body 11, and the right second cutout 17 is arranged in an intermediate position closer to the back than the center in the first direction H1 of one side of the attachment body 11. In other words, on the opposing sides facing each other in the second direction H2, the second cutout 17 is not formed to the end, leaving corners. Therefore, when the attachment 10 is attached to the through-hole 110 of the pallet 100 (see FIG. 2A), the two diagonally opposite corners of the attachment 10 (and the side edges sandwiching these corners) face the inner surfaces of the through-hole 110, preventing the attachment 10 from rattling or rotating.

[0028] The portions of the hanging wall 13 of the attachment body 11 that correspond to the notches 16 and 17 are bent toward the center of the main plate 12. In addition, the portions of the hanging wall 13 other than the notches 16 and 17 have a lower one-third area that is slightly inward in a stepped manner.

[0029] These cutouts 16, 17 create a gap for draining water between the cylindrical wall 111A and the outer edge of the attachment 10 when the attachment 10 is attached to the through-hole 110 of the pallet 100 (see FIG. 2A). Water drains through the cutouts 16, 17 and the drainage hole 15, making it less likely for water to accumulate in the attachment 10 and reducing the impact of water on communication by the wireless communication device 90. Dust and other foreign matter also less likely to accumulate in the attachment 10. Note that, although the cutouts 16, 17 are arranged on all sides of the square of the attachment body 11 in this embodiment, they may be arranged on only some of the sides.

[0030] 6A and 6B, the multiple engagement pieces 30, 40 are arranged, one on each side of the attachment body 11, so as to be located toward the left end when that side is placed toward the front, and are rotationally symmetric so that they overlap when the attachment 10 is rotated by 90°. In other words, the engagement pieces 30, 40 are arranged point-symmetrically and asymmetrically.

[0031] In this way, the engagement pieces 30, 40 are disposed on the left side of each side, and the upper engagement ridges 112 are also disposed on the left side of each tube-constituting wall 111A, so the arrangement of the engagement pieces 30, 40 corresponds to the arrangement of the upper engagement ridges 112. Furthermore, when the attachment 10 is turned upside down (see FIG. 6B), the arrangement of the engagement pieces 30, 40 corresponds to the arrangement of the lower engagement ridges 113 of the through hole 110.

[0032] Furthermore, the engagement pieces 30, 40 are arranged on each side of the attachment body 11 near the end opposite the notches 16, 17, so that the engagement pieces 30, 40 and the notches 16, 17 do not overlap in a plan view.

[0033] The multiple engagement pieces 30, 40 include a pair of first engagement pieces 30 arranged on a pair of opposing sides of the attachment body 11 that face each other in the second direction H2, and a pair of second engagement pieces 40 arranged on a pair of opposing sides that face each other in the second direction H2. As shown in FIG. 6 , the first and second engagement pieces 30, 40 each have a main plate portion 31, 41 that hangs down from the inside of the hanging wall portion 13 of the attachment body 11, and an engagement protrusion 35, 45 that protrudes outward from the tip of the main plate portion 31, 41 (i.e., toward the inner surface of the through hole 110 when attached). The tip of the back surface of the main plate portion 31, 41 is bent outward. The second engagement piece 40 is offset from the extension area of ​​the opening of the holder fitting portion 14 in the second direction H2.

[0034] Additionally, side reinforcements 32, 42 are provided on both sides of the outer surface of the main plate 31, 41, extending from the hanging wall 13 of the attachment body 11. The side reinforcements 32, 42 extend to a position just before the engaging protrusions 35, 45, and their lower portions are inclined downward to approach the outer surface of the main plate 31, 41. A triangular rib 33, 43 extending vertically is provided at the horizontal center on the back surface of the main plate 31, 41. The triangular rib 33, 43 extends from the underside of the attachment body 11 to the tip of the main plate 31, 41, approaching the back surface of the main plate 31, 41. The triangular rib 33 of the first engaging piece 30 protrudes more than the triangular rib 43 of the second engaging piece 40.

[0035] As shown in FIG. 8 , the engagement protrusion 35 of the first engagement piece 30 (hereinafter referred to as the "first engagement protrusion 35") has a locking surface 35B that is perpendicular to the outer surface of the main plate 31, and a guide surface 35A that slopes to connect the tip of the locking surface 35B and the tip of the main plate 31. When the attachment 10 is attached to the through hole 110, the locking surface 35B of the first engagement protrusion 35 faces the locking surface 112B of the upper engagement ridge 112 from below. Furthermore, the tip of the first engagement protrusion 35 in the second direction H2 abuts against or is close to the inner surface of the through hole 110. In other words, the first engagement protrusion 35 engages with substantially the entire locking surface 112B of the upper engagement ridge 112.

[0036] 9, the engaging protrusion 45 of the second engaging piece 40 (hereinafter referred to as the "second engaging protrusion 45") has a locking surface 45B that is perpendicular to the outer surface of the main plate 41, an intermediate surface 45C that hangs down from the tip surface of the locking surface 45B, and a guide surface 45A that slopes to connect the tip of the intermediate surface 45C and the tip of the main plate 31. The locking surface 45B of the second engaging protrusion 45 abuts against the locking surface 112B of the upper engaging rib 112, similar to the locking surface 35B of the first engaging protrusion 35 (see FIG. 8), but its length in the first direction H1 is about half the length of the locking surface 112B of the upper engaging rib 112. In other words, the second engaging protrusion 45 protrudes less than the first engaging protrusion 35, and its engagement depth with the upper engaging rib 112 is also smaller.

[0037] When attaching attachment 10 to the upper opening of through-hole 110, attachment 10 is oriented to match the planar shape of through-hole 110 and inserted into through-hole 110 via multiple engagement pieces 30, 40. After guide surfaces 35A, 45A of engagement protrusions 35, 45 of multiple engagement pieces 30, 40 come into contact with guide surface 112A of upper engagement ridge 112 of through-hole 110, when attachment 10 is further pushed in, guide surfaces 35A, 45A, 112A come into frictional contact with each other, and engagement pieces 30, 40 are elastically deformed.

[0038] When the engaging protrusions 35, 45 pass the upper engaging ridge 112, the engaging pieces 30, 40 elastically return to their original position, and the locking surfaces 35B, 45B of the engaging protrusions 35, 45 face the locking surface 112B of the upper engaging ridge 112. This prevents the attachment 10 from slipping out while fitted into the through-hole 110. Furthermore, the lower portions of the side reinforcing portions 32, 42 of the engaging pieces 30, 40 come into contact with the guide surface 112A of the upper engaging ridge 112, preventing the attachment 10 from falling deep into the through-hole 110.

[0039] When attaching the attachment 10 to the lower opening of the through-hole 110, the attachment 10 is similarly turned upside down and inserted into the through-hole 110 via the multiple engagement pieces 30, 40. The attachment 10 is then pushed in until the engagement protrusions 35, 45 pass the lower engagement ridge 113, and the locking surfaces 35B, 45B of the engagement protrusions 35, 45 face the locking surface 113B of the lower engagement ridge 113. This prevents the lower attachment 10 from slipping out of the lower opening of the through-hole 110.

[0040] The protrusion amount of the upper engagement protrusion 112 and the lower engagement protrusion 113 is approximately 1 / 5 of the distance from the cylindrical wall 111A of the through-hole 110 to the opening of the holder fitting portion 14, so that the movable area where the first engagement piece 30 elastically deforms does not overlap with the extended area of ​​the opening of the holder fitting portion 14. Furthermore, the second engagement piece 40 is offset from the extended area of ​​the opening of the holder fitting portion 14 in the second direction H2, so that even if the second engagement piece 40 elastically deforms, it does not overlap with the extended area of ​​the opening of the holder fitting portion 14. As a result, even when the attachment 10 is attached to the through-hole 110 while holding the communicator holder 91, or when the engaging pieces 30, 40 rattle due to an impact to the pallet 100, for example, the engaging pieces 30, 40 do not come into contact with the communicator holder 91, and damage or detachment of the engaging pieces 30, 40 and the communicator holder 91 is prevented.

[0041] Furthermore, since the second engagement protrusion 45 protrudes less than the first engagement protrusion 35 and the elastic deformation of the second engagement piece 40 is smaller than the elastic deformation of the first engagement piece 30, the attachment 10 can be attached with less force than if the engagement protrusion 45 of the second engagement piece 40 protruded the same amount as the first engagement protrusion 35. In this embodiment, the drainage hole 15 is disposed closer to the second engagement piece 40 in its extension direction (first direction H1). Therefore, the elastic deformation of the first engagement piece 30, which has a larger engagement amount than the second engagement piece 40, is less affected by the drainage hole 15, and a decrease in engagement force due to the drainage hole 15 is suppressed. Furthermore, since the planar shapes of the through hole 110 and the attachment 10 are both square, the attachment 10 can be attached in multiple rotational positions, making the attachment operation easier.

[0042] Furthermore, the attachment 10 holds the communication device holder 91 housed in the through-hole 110, preventing the communication device holder 91 from coming into contact with foreign objects, and the attachment 10 itself also prevents contact with foreign objects by fitting inside the through-hole 110. Moreover, the communication device holder 91 is cantilevered by the holder fitting portion 14 and is suspended inside the through-hole 110, so that even if the pallet 100 receives an impact, the communication device holder 91 is less likely to be impacted.

[0043] The communicator holder 91 may be attached to the attachment 10, and then the attachment 10 may be attached to the through-hole 110, or only the attachment 10 may be attached to the through-hole 110, and then the communicator holder 91 may be attached to the attachment 10. In other words, even when the attachment 10 is attached to the through-hole 110, the communicator holder 91 can be attached from the outer surface side of the attachment main body 11, making it possible to retrofit the communicator holder 91 to a pallet 100 to which an attachment 10 has already been attached. Furthermore, it is possible to attach the attachment 10 to the through-hole 110 with the communicator holder 91 engaged, or to accommodate the communicator holder 91 after the attachment 10 has been attached to the through-hole 110, allowing the worker to select the attachment procedure.

[0044] Furthermore, in this embodiment, engaging protrusions 112, 113 are arranged both near the upper end and near the lower end of the through hole 110, so that the attachment 10 can be attached to the through hole 110 from any direction, and the attachment 10 can be attached regardless of the orientation of the placed pallet 100.

[0045] As described above, according to this embodiment, the communication device holder 91 is attached to the pallet 100 via the attachment 10, and by changing to an attachment with a holder fitting portion 14 having a different shape depending on the shape of the communication device holder, it becomes possible to attach a variety of communication device holders to the pallet 100. This also makes it possible to select the type of wireless communication device depending on the application.

[0046] Furthermore, when there are multiple types of conveying devices including pallets, it is possible to change only the attachment depending on the structure of the conveying device and reuse the communication device holder, or it is possible to attach a communication device holder that can be attached directly to a conveying device to another conveying device by using an attachment.

[0047] [Other embodiments] In the above embodiment, the pallet 100 is a welded pallet, but it may also be an integrally molded pallet in which the pallet is molded as a single piece.

[0048] In the above embodiment, the attachment 10 is attached to the pallet 100, but it may also be attached to other transporting means such as a cart or a protector attached to the end of a roll.

[0049] The attachment 10 that holds the communication device holder 91 may be attached to the lower end opening of the through-hole 110, and only the attachment 10 may be attached to the upper end opening. Also, the attachment 10 that does not hold the communication device holder 91 may not be attached.

[0050] In the above embodiment, the communication device holder 91 is housed in the through-hole 110, but it may also be housed in a recess having a bottom.

[0051] A through-hole or recess for accommodating the communication device holder 91 may be open to the side surface of the pallet 100 .

[0052] Although the wireless communication device 90 in the above embodiment is a passive tag, it may be an active tag.

[0053] In the above embodiment, the holder fitting portion 14 penetrates the attachment body 11, but it may also be configured not to penetrate the attachment body 11, but to protrude from the attachment body 11 to the back side of a through-hole or recess and have a fitting wall into which the communicator holder 91 fits. In this case, the communicator holder 91 is attached to the attachment 10 from the back side.

[0054] In the above embodiment, the communication device holder 91 is fitted to the attachment 10, but it may be configured not to be fitted as long as it is detachably engaged.
