As shown in FIG. 3 , each section of the motor receiving tray 10 is divided into a plurality of recessed portions 45 by a plurality of bulging portions 25 , 30 , 35 , 40 and sub-ridge portions 22A to 22F. All the recessed portions 45 have a shape that narrows toward the lower end (a tapered shape). In addition, in the above-mentioned recessed portion 45 , the recessed portion 45 surrounded by the tray side wall 12 , the third sub-ridge portion 22C, the fourth sub-ridge portion 22D, and the second and fourth bulging portions 30 and 40 is filled with cushioning material. For convenience, this recess 45 will be referred to as “protection recess 45A” below.

As described above, the motor receiving tray 10 is a vacuum-formed product, so the recessed portion 45 forms a protrusion when viewed from the back side, and the bulging portions 25, 30, 35, 40, central ridge portion 20, etc. form a recessed portion when viewed from the back side. (Refer to Figure 8). Here, in the motor receiving tray 10 of this embodiment, the central groove portion 50 is formed on the back side of the central ridge portion 20 , and the first bulging portion 25 of each segment is formed on the back side from the central groove portion 50 to the left and right. One side groove portion 51 protrudes.

The structure of the motor receiving tray 10 has been described above. Therefore, the two motors 90 can be arranged on one motor receiving tray 10 as follows. That is, as shown in FIG. 2 , the first motor 90 is arranged on the motor receiving tray 10 in such a manner that the motor main body part 90A is arranged in one section (for example, the left section) so as to pass through the first bulge. The line between the portion 25 and the second bulging portion 30 serves as a diagonal quadrangular main arrangement region R1, and the wire harness 90B is arranged across the first bulging portion 25 in other sections (for example, the right section). The sub-arrangement region R2 located on the opposite side to the second bulging portion 30 accommodates it. Moreover, when the motor main body part 90A is arrange|positioned in the main arrangement area R1, the functional part 90C is arrange|positioned in the protection recessed part 45A.

The first to fourth bulges 25, 30, 35, and 40 are all accommodated in the main arrangement region R1. In addition, the motor main body portion 90A arranged in the main arrangement region R1 is in contact with and supported by the support portions 25S, 30S, 35S, and 40S in the first to fourth bulging portions 25, 30, 35, and 40 (in FIG. 3 and other examples). Shown in gray). In FIG. 4 , a state in which the motor main body portion 90A is supported by the support portion 25S of the first bulging portion 25 is shown. Since the support parts 25S, 30S, 35S, and 40S are inclined with respect to the left-right direction and the up-down direction, the movement of the motor main body part 90A in the left-right direction is also restricted. It should be noted that the support part 25S of the first bulging part 25 is composed of a part of the first structural wall 26A and the second structural wall 26B shown in FIG. The first to third protruding portions 33A to 33C are shown as a part. In addition, the support portion 35S of the third bulging portion 35 is composed of a part of the first and second protruding portions 35B and 35C shown in FIG. 7 , and the supporting portion 40S of the fourth bulging portion is composed of the left protruding portion 41E and the inclined surface 42A. part of the composition.

In addition, restricting portions 30K, 35K, and 40K are arranged in the second to fourth bulging portions 30, 35, and 40. These restricting portions come into contact with the motor main body portion 90A in the front-rear direction to restrict the movement of the motor main body portion 90A in the front-rear direction (see Figure 6 and Figure 7). 10 shows a state in which the lower protruding portion of the motor main body portion 90A is sandwiched between the restricting portions 35K and 40K of the third and fourth bulging portions 35 and 40 so that the motor 90 is in the front-rear direction. Movement is restricted and motor 90 has difficulty rotating. It should be noted that the restricting portion 30K of the second bulging portion 30 is composed of the rearward side surface of the protrusion 32T, and the restricting portion 35K of the third bulging portion 35 is composed of the side surface facing the fourth bulging portion 40 side. The restricting portion 40K of the fourth bulging portion 40 is formed from a side surface facing the third bulging portion 35 side.

It should be noted that the first to fourth bulging parts 25, 30, 35, and 40 are equivalent to the "support bulging part" and the "first limiting bulging part" in the technical solution. The second, third, and fourth The bulge portions 30, 35, and 40 correspond to the "second restriction bulge portion" in the technical solution.

As shown in FIG. 2 , the sub-arrangement area R2 is formed in a strip shape orthogonal to one end of one side of the main arrangement area R1. Furthermore, the main arrangement area R1 and the sub-arrangement area R2 constitute a flagpole-shaped motor arrangement area R in which one motor 90 is arranged.

The second motor 90 is arranged on the motor receiving tray 10 in such a manner that the first motor 90 is accommodated in a direction rotated 180 degrees, and the motor main body part 90A is arranged in the main arrangement of another section (for example, the right section) In the region R1, the wire harness 90B is arranged in a sub-arrangement region R2 of one section (for example, the left section). In other words, the second motor arrangement area R and the first motor arrangement area R are arranged in a rotationally symmetrical manner. The above-mentioned two motor arrangement areas R are configured such that the sub-arrangement area R2 is along either side of the adjacent main arrangement area R1.

Next, the transport container 70 will be described based on FIG. 11 . The transport container 70 has a container bottom wall 71 having a size such that two motor receiving trays 10 are arranged vertically and horizontally, L-shaped pillars 72A provided at the four corners of the container bottom wall 71 , and lattice-shaped container side walls. 72B, which is erected between the pillars 72A. Below the container bottom wall 71, a lower frame 71B having substantially the same size as the outer edge of the container bottom wall 71 is provided, and the lower frame 71B is connected to the container bottom wall 71 through a plurality of cross beam portions 71A. A fork of a forklift can be inserted between the cross beam portions 71A. Moreover, the support|pillar 72A protrudes above the container side wall 72B, and accommodates the lower frame 71B of another transport container 70 in the inner side, and it is possible to stack the transport containers 70 mutually.

On the bottom wall 71 of the container, two rectangular support frames 73 that are slightly smaller than the outer edge of the motor receiving tray 10 are arranged side by side, two vertically and one horizontally. A center protrusion 74 connecting the center portions of a pair of long sides of the support frame 73 and side protrusions 75 protruding one to the left and right from the center protrusion 74 are formed inside each support frame 73 . The left and right side protrusions 75 are separated by a distance of approximately 1/2 to 1/3 of the length of the central protrusion 74 and extend in opposite directions. Specifically, the left side ridge 75 is located behind the front long side of the support frame 73 and is spaced apart from the front long side of the support frame 73 by about 1/3 to 1/4 of the length of the central ridge 74 . And extends from the central protrusion 74 to the left. The right side protrusion 75 is located in front of the long side of the rear side of the support frame 73 and is separated from the long side of the rear side of the support frame 73 by 1 of the length of the central protrusion 74 . /3~1/4 and extends from the central protrusion 74 to the right. In other words, the container bottom wall 71 is formed with a main protrusion (central protrusion 74) extending in a predetermined direction; and a first side protrusion (for example, the left side protrusion 75) extending from the main protrusion (center protrusion 74). The protrusion 74) continuously extends to one of the intersecting directions intersecting the predetermined direction; and the second side protrusion (for example, the right side protrusion 75) is separated from the first side protrusion in the predetermined direction and separated from the first side protrusion. The main protrusion (center protrusion 74) extends continuously toward the other side in the intersecting direction. In addition, the cross sections of the central protrusion 74 and the side protrusions 75 both have a rectangular shape.

As shown in FIGS. 12 to 14 , when the motor receiving tray 10 is placed such that the recessed portion 45 is received in the support frame 73 of the transport container 70 , the central groove portion 50 and the side grooves of the motor receiving tray 10 The portion 51 is respectively engaged with the central protrusion 74 and the side protrusion 75 of the transport container 70 in a concave and convex manner. At this time, both sides of the central protrusion 74 are sandwiched between a pair of inner side surfaces of the central groove portion 50 (inner side surfaces of a pair of side walls 20B of the central ridge portion 20 ). In addition, as shown in FIG. 13 , the bottom wall 14A of the recessed portion 14 of the flange portion 13 comes into contact with the upper surface of the support frame 73 , so that the flange portion 13 is supported. Furthermore, a gap is formed between the tray side wall 12 and the support frame 73 .

It should be noted that the central groove part 50 and the side groove part 51 correspond to the "engagement recessed part" in the technical solution, and the central protrusion 74 and the side protrusion 75 correspond to the "engagement convex part" in the technical solution. The support frame 73 is equivalent to the "flange support part" in the technical solution.

The above is the description of the structure of this embodiment. Next, the operation and effect of this embodiment will be described. First, the motor storage tray 10 is placed on the transport container 70 in an empty state. Then, the motors 90 are received in the motor receiving tray 10 in such an orientation that they are rotated 180 degrees relative to each other.

When the motor 90 is arranged on the motor receiving tray 10 , the bulges 25 , 30 , 35 , and 40 support the motor main body 90A and restrict the movement of the motor main body 90A in the horizontal direction. Here, the portion of the conventional tray that supports the motor has a structure that is manufactured by bonding to the tray main body. On the other hand, since the motor receiving tray 10 of this embodiment is integrally formed by vacuum forming, the effort required for manufacturing can be suppressed.

In addition, two motors 90 can be arranged in one motor receiving tray 10. The two motor arrangement areas R are formed to be rotationally symmetrical, and the sub-arrangement area R2 is along one side of the main arrangement area R1 of the adjacent motor arrangement area R. Therefore, The free space is reduced and the containment efficiency is improved. Also, the front ends of the wire harnesses are arranged away from each other, thus preventing the wire harnesses from being entangled with each other.

In addition, by forming the recessed portion 14 in the flange portion 13 of the motor receiving tray 10, the side wall 14B described above functions as a rib, thereby improving the strength of the motor receiving tray 10. Furthermore, since the recessed portion 14 has a groove shape and one end thereof is located halfway in the width direction of the flange portion 13, side walls 14B are also formed in the direction along the tray side wall 12, thereby further strengthening the flange portion.

Furthermore, when the motor receiving tray 10 is placed on the transport container 70, the flange portion 13 is supported by the support frame 73, thereby preventing the motor receiving tray 10 from being crushed by the flange portion 13 or the tray side wall 12 falling over. Deformation occurs. Furthermore, since the support frame 73 of the transport container 70 is in contact with the recessed portion 14 of the flange portion 13 from the back side, the reinforced portion is supported, and the flange portion 13 is supported more stably.

In addition, when the motor receiving tray 10 is placed on the transport container 70, the central groove portion 50 and the side groove portions 51 of the motor receiving tray 10 are respectively engaged with the central protrusion 74 and the side protrusion 75 of the transport container 70. Therefore, the movement of the motor receiving tray 10 relative to the transport container 70 and the shaking in the front-rear direction and the left-right direction are restricted. Here, it is also conceivable to not provide the central protrusion 74 and the side protrusions 75 but to configure the support frame 73 of the transport container 70 to be in contact with the tray side wall 12 of the motor receiving pallet 10 to restrict the motor receiving pallet. 10 offset, but the smaller the reference dimension, the smaller the tolerance can be. Therefore, the clearance between the central groove part 50 and the side groove part 51 and the central protrusion 74 and the side protrusion 75 is smaller than the clearance between the support frame 73 and the pallet side wall. The clearance between the motor receiving trays 12 is more easily reduced, so that the shaking of the motor receiving tray 10 is suppressed. In addition, the central groove portion 50 and the side groove portions 51 also serve as the central ridge portion 20 and the first bulging portion 25. Therefore, there is no need to provide protrusions for the central groove portion 50 and the side groove portions 51, and the arrangement of the motor 90 will not be affected. to influence. In addition, since the central protrusion 74 and the side protrusions 75 have a rectangular shape, the movement of the motor receiving tray 10 is restricted at two points in the width direction, and rotation of the motor receiving tray 10 is also prevented. In particular, since both sides of the central protrusion 74 are sandwiched between a pair of inner surfaces of the central groove 50 (the inner surfaces of a pair of side walls 20B of the central ridge 20 ), the rotation of the motor receiving tray 10 is further restricted. .

(2) Alternatively, only one motor arrangement region R may be formed in one motor receiving tray 10 .

(3) In the transport unit 100 of the above embodiment, the number of motor receiving trays 10 that can be placed on the transport container 70 is four. However, the number may be one to three, or may be five or more. In the case of a structure capable of mounting two motor receiving trays 10 , the two motor receiving trays 10 may be arranged in either vertical or horizontal direction.

(4) In the above embodiment, the support frame 73 is continuous over the entire circumference, but it may be discontinuous. In addition, in the above-described embodiment, the support frame 73 is in contact with all of the plurality of recessed portions 14, but it may be in contact with only a part.

(5) In the above embodiment, the deviation of the motor receiving tray 10 relative to the transport container 70 is controlled by the engagement between the central groove portion 50 and the central protrusion 74 and the engagement between the side groove portion 51 and the side protrusion 75 . The restriction can also be only the engagement of any one of them.

(6) In the above-mentioned embodiment, the cross-sectional shape of the central protrusion 74 and the side protrusion 75 is a solid rectangle, but they may be a hollow rectangle, a door shape, an L-shape, or the like. In addition, the central protrusion 74 and the side protrusions 75 may be composed of double walls.

(7) In the above embodiment, the central protrusion 74 is connected between a pair of opposing sides (long sides) of the support frame 73 , or it may be connected only between one side of the support frame 73 and the side protrusions 75 (in other words). In other words, the overall shape of the protrusions may be L-shaped), or only the side protrusions 75 may be connected to each other (in other words, the overall shape of the protrusions may be formed into a Z-shape).

(8) The central protrusion 74 and the side protrusions 75 may not be connected to each other but may be arranged separately.

(9) In the above embodiment, the central protrusion 74 extends in the front-rear direction, and the side protrusions 75 extend in the left-right direction. However, the reverse may be possible, and the central protrusion 74 and the side protrusions 75 may extend in the front-rear direction and the left-right direction. extends in other directions. In addition, the central protrusion 74 does not need to be orthogonal to the side protrusions 75 .

It should be noted that the formation positions and shapes of the central groove portion 50 and the side groove portions 51 (engagement recessed portions) can be appropriately changed to match the formation positions and shapes of the center protrusion 74 and the side protrusions 75 (engagement protrusions). correspond. In addition, the formation positions and shapes of the central protrusion 74 and the side protrusions 75 (engagement protrusions) can be appropriately changed to match the formation positions and shapes of the central groove 50 and the side grooves 51 (engagement recesses) in the motor receiving tray 10 .
