[0011] [Work Palette Configuration] A work pallet 1 according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] FIG. 1 is a perspective view illustrating the appearance of a work pallet 1 according to an embodiment of the present invention.

[0013] The work pallet 1 is a pallet on which a predetermined processing can be performed on the work while the work is placed on it, and is a so-called skid pallet formed by multiple slats (also called plate-shaped crosspieces) that support the work and are arranged at predetermined intervals.

[0014] In this embodiment, the workpiece is a metal formed into a plate shape, and is cut into a predetermined shape or drilled by a processing machine such as a laser processing machine (not shown). In this embodiment, the workpiece is subjected to the above processing while being placed on the work pallet 1.

[0015] In this embodiment, an unmachined workpiece is placed on a work pallet 1 and carried into a laser processing machine, which is an example of a processing machine, and laser processing is performed while the workpiece is placed on the work pallet 1. When the laser processing is completed, the processed workpiece is carried out from the laser processing machine while still placed on the work pallet 1.

[0016] Fig. 2 is a perspective view illustrating a slat unit frame 20 constituting the work pallet 1. Fig. 3 is a perspective view illustrating a state in which one of the slat units 10 is assembled into the slat unit frame 20.

[0017] The work pallet 1 includes a plurality of slat units 10 and a slat unit frame 20 on which the plurality of slat units 10 are arranged side by side.

[0018] The slat unit 10 has a plurality of slats 11 for supporting a workpiece. The plurality of slats 11 are removably attached to the unit body 10A, in particular to a slat support member 102 and an oblique member 103 (see FIG. 5) described below.

[0019] In this embodiment, as shown in FIG. 1, four slat units 10 are arranged in one slat unit frame 20, lined up in a direction perpendicular to the longitudinal direction of the slats 11.

[0020] In the work pallet 1, each of the slat units 10 can be fastened to a part of the slat unit frame 20 by a locking mechanism that allows attachment and detachment, such as by bolting, when in use to place a workpiece thereon. The slat units 10 may be supported by a part of the slat unit frame 20 and pressed against the slat unit frame 20 by their own weight.

[0021] As a result, as shown in Figs. 1 to 3, each of the multiple slat units 10 can be individually removed from the slat unit frame 20 or individually attached to it.

[0022] [Slat unit configuration] Next, the configuration of the slat unit 10 will be described.

[0023] Fig. 4 is a perspective view illustrating the appearance of the slat unit 10. Fig. 5 is a diagram illustrating the unit body 10A. Fig. 6 is a diagram illustrating a state in which one of the slats 11 is attached to the unit body 10A.

[0024] As shown in FIGS. 4 and 5, the slat unit 10 has a unit body 10A and a plurality of slats 11 attached to the unit body 10A.

[0025] As shown in FIG. 5, the unit body 10A has a pair of fixing slats 101, a plurality of slat support members 102, and a plurality of diagonal members 103.

[0026] Each of the fixing slats 101 has a plurality of supporting protrusions 111 extending along the longitudinal direction of the fixing slats 101, and is capable of supporting a workpiece by the supporting protrusions 111. In other words, the fixing slats 101 constitute the frame of the unit body 10A, and also function as one of the slats that support the workpiece.

[0027] Each of the fixing slats 101 has a slot-shaped opening 121 extending in the longitudinal direction formed at both longitudinal ends of the fixing slat 101. The opening 121 functions as a handle that a user can grasp when replacing the slat unit 10, for example.

[0028] 5, the slat support member 102 supports a pair of fixing slats 101 at a predetermined distance. Both ends of the slat support member 102 are fastened to the fixing slats 101 by bolts 104. This makes it possible to hold the pair of fixing slats 101 in a state spaced apart at a predetermined distance.

[0029] In this embodiment, the slat support member 102 includes an insertion support member 102A into which the slat 11 can be easily inserted and removed, and a retaining support member 102B in which a structure for preventing the slat 11 from falling out is formed.

[0030] The insertion support member 102A is formed with a plurality of straight support grooves 210 that individually support a plurality of slats 11. The straight support grooves 210 have groove walls that are linearly formed along the insertion direction F of the slats 11.

[0031] The retaining support member 102B supports the multiple slats 11 individually and has retaining support grooves 220 formed therein that have a retaining structure for preventing the supported slats 11 from easily falling out. The retaining support grooves 220 will be described later (see Figs. 7 and 8).

[0032] In this embodiment, the retaining support member 102B is disposed in the center in the longitudinal direction of the pair of fixing slats 101 (see FIG. 5). The insertion support members 102A are disposed at positions to support both sides of the retaining support member 102B and both ends in the longitudinal direction of the pair of fixing slats 101 (see FIG. 5).

[0033] The diagonal members 103 are disposed between the multiple slat support members 102 in a direction intersecting the slat support members 102. Both ends of the diagonal members 103 are fastened to the pair of fixing slats 101, respectively, by bolts 104.

[0034] [Explanation of the engagement part between the slat support member and the slat] Next, the engagement portion between the slat support member 102 (prevention support member 102B) and the slat 11 will be described.

[0035] Fig. 7 is an enlarged view illustrating an engagement portion between the retaining and supporting member 102B and the slat 11. Fig. 8 is an enlarged view illustrating a state in which the slat 11 is attached to the retaining and supporting member 102B.

[0036] As shown in FIGS. 7 and 8, the slat 11 has, at a lower end portion 11B thereof, a pair of legs 131, 132 and a receiving portion 133 located between the legs 131, 132 for receiving the retaining support member 102B.

[0037] The legs 131, 132 extend downward from the lower end 11B of the slat 11 toward the outside of the slat 11, and are formed with a gap W1 wider than the thickness D1 of the retaining support member 102B. The receiving portion 133 is located between the pair of legs 131, 132, and is adapted to come into contact with the bottom of the retaining support groove 220 when the slat 11 is fitted into the retaining support member 102B (see FIG. 9).

[0038] A through hole 134 is formed in the slat 11, penetrating the slat 11 in the thickness direction. The through hole 134 is formed in the slat 11 on the inside of a receiving portion 133 formed in a lower end portion 11B of the slat 11.

[0039] In an embodiment, the groove center C1 (FIG. 5) of the straight support groove 210 may be formed in the plane of the insertion support member 102A at a predetermined angle with respect to the insertion direction F of the slat 11. When the straight support groove 210 is formed at an angle, it is preferable to set the angle of inclination to 3 degrees.

[0040] FIG. 9 is an enlarged view illustrating the retaining support groove 220 formed in the retaining support member 102B.

[0041] 9, the retaining support groove 220 has a main groove portion 221. A convex portion 222 is formed on the inner side of the main groove portion 221. A support recess 223 is further formed in the main groove portion 221.

[0042] The main groove 221 extends from the upper end 112A of the retaining support member 102B toward the inside of the retaining support member 102B, that is, along the insertion direction F of the slat 11. The main groove 221 is formed so as to receive a part of the lower end 11B of the slat 11 therein.

[0043] The protrusion 222 is formed on the upper end 112A side of the retaining support member 102B in the main groove portion 221. The protrusion 222 is formed to protrude from the groove wall of the main groove portion 221 toward the inside of the groove. The protrusion 222 forms a narrowed groove portion 224 having a groove width W3 narrower than the groove width W2 of the main groove portion 221 and wider than the thickness D2 of the slat 11.

[0044] In this embodiment, the groove center C3 of the narrowing groove portion 224 and the supporting recess 223 are formed to be offset from each other.

[0045] The support recess 223 is narrower than the groove width W2 of the main groove portion 221, and is recessed further from the bottom 221B of the main groove portion 221 in the insertion direction F of the slat 11. The support recess 223 is formed at a position offset from the bottom center (groove center C2) of the main groove portion 221. The lower end portion 11B of the slat 11 inserted into the main groove portion 221 abuts against the support recess 223.

[0046] When fitting the slat 11 into the retaining support member 102B, the receiving portion 133 of the slat 11 is inserted into the main groove portion 221, and then the slat 11 is moved so that the receiving portion 133 abuts against the support recess 223. Next, the angle of the slat 11 is changed so that the protrusion 222 is inserted into the through hole 134, and the slat 11 is positioned.

[0047] [effect] The work pallet 1 according to this embodiment includes a plurality of slat units 10 and a slat unit frame 20 on which the slat units 10 are arranged side by side. As a result, in the work pallet 1, each of the plurality of slat units 10 can be individually removed from the slat unit frame 20.

[0048] Therefore, according to the work pallet 1, the slat units 10 can be easily replaced individually depending on the degree of deterioration of each slat unit 10. Therefore, the maintainability of the work pallet 1 can be improved.

[0049] Further, according to this embodiment, in the slat unit 10, the multiple slats 11 are removably attached to the unit body 10A.

[0050] Therefore, the slats 11 can be replaced individually one by one depending on the degree of deterioration, and the maintainability of the work pallet 1 can be improved.

[0051] In the slat unit 10, each of the fixing slats 101 constituting the unit body 10A constitutes the frame of the unit body 10A and also functions as a slat for supporting a workpiece.

[0052] For this reason, when the slat units 10 are arranged side by side on the slat unit frame 20, no area without slats is formed at the boundary between adjacent slat units 10. This makes it possible to prevent the workpiece from falling off the work pallet 1, the workpiece from slipping on the work pallet 1, and the like.

[0053] In the work pallet 1, a pair of fixing slats 101, a plurality of slat support members 102 (insertion support members 102A, anti-slip support members 102B) and a plurality of diagonal members 103 are formed so as to be separable from each other, and are fastened and held in place by bolts 104.

[0054] The unit body 10A can obtain a good strength with such a simple structure. The fixing slat 101, the plurality of slat support members 102, and the plurality of diagonal members 103 are fastened by the bolts 104.

[0055] Therefore, the unit body 10A can be disassembled into the fixing slats 101, the slat support members 102, and the diagonal members 103. This makes it easy to replace each of the fixing slats 101, the slat support members 102, and the diagonal members 103. This improves maintainability.

[0056] Each of the fixing slats 101 has an opening 121 formed therein that functions as a handle to be held by a user when, for example, replacing the slat unit 10. This makes it easier to replace the slat unit 10, improving the efficiency of the replacement work.

[0057] The anti-slip support member 102B and the slat 11 are positioned by abutment between a receiving portion 133 between a pair of legs 131, 132 formed on the lower end portion 11B of the slat 11 and a support recess 223 formed in the anti-slip support groove 220.

[0058] After the receiving portion 133 of the slat 11 is inserted into the main groove portion 221, the slat 11 is moved so that the receiving portion 133 abuts against the support recess 223. Next, the slat 11 is positioned so that the protrusion 222 is inserted into the through hole .

[0059] As a result, the protrusions 222 are inserted into the through holes 134. This makes it possible to prevent the slats 11 from slipping out of the retaining support members 102B.

[0060] Furthermore, in the insertion support member 102A, when the groove center C1 of the straight support groove 210 is formed at a predetermined angle with respect to the insertion direction F of the slat 11, the slat 11 inserted into the straight support groove 210 can lean against the groove wall of the straight support groove 210 and is supported by the groove wall by its own weight. This makes it possible to reduce rattling between the slat 11 and the slat support member 102 (insertion support member 102A, fall-out prevention support member 102B) caused by vibration of the work pallet 1.

[0061] [Other embodiments] Although the embodiments of the present invention have been described above, the above-mentioned embodiments merely illustrate some of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above-mentioned embodiments.

[0062] The number of slat units 10 that can be arranged in one slat unit frame 20 is arbitrary and is not limited to the four described in this embodiment. The number of slats 11 arranged in the slat unit 10 is also not limited to the example shown in the figures.

[0063] In this embodiment, the shape of the supporting protrusion 111 is not limited to the triangular shape shown in the figure.

[0064] In the present embodiment, the anti-slip support member 102B is described as being disposed in the longitudinal center of the pair of fixing slats 101 (see FIG. 5). The position at which the anti-slip support member 102B is disposed is not limited to the longitudinal center of the pair of fixing slats 101. For example, the anti-slip support member 102B may be disposed in a position that supports one end of the pair of fixing slats 101 in the longitudinal direction.

[0065] In the present embodiment, the description has been given of one anti-slip support member 102B being disposed in the center in the longitudinal direction of the pair of fixing slats 101 (see FIG. 5). However, in the present embodiment, there may be a plurality of anti-slip support members 102B.

[0066] Similarly, the positions of the insertion support members 102A are not limited to the positions supporting both sides of the retaining support member 102B and both longitudinal ends of the pair of fixing slats 101. The number of the insertion support members 102A is also not limited to that in the embodiment. [Explanation of symbols]
