Is divided into three equal parts into three divided grooves 30A.

  As shown in FIG. 6, the cutout portions 27 are formed at the center and both end portions of each dividing groove 30 </ b> A in the longitudinal direction. The notch 27 at the center of each divided groove 30A is formed by cutting a part of the groove side wall 24 into a horizontally long rectangle and cutting the bottom wall 25 from the groove side wall 24 to the first side wall 11 with the same width. Further, both upper corners of the notch 27 in the groove side wall 24 are chamfered in an arc shape. Further, the cutout portions 27 at both ends of each divided groove 30A have a shape in which the central cutout portion 27 is halved, and the cutout portions 27 and 27 at the end portions are joined between the adjacent divided grooves 30A and 30A. It has substantially the same shape as the central notch 27. The lower surfaces of the groove end wall 26 and the partition wall 31 are flush with the upper inner surface of the notch 27. As shown in FIG. 4, a step surface 11D having the same shape as the outer shape of the notch 27 in the groove side wall 24 is formed on the inner surface of the first side wall 11, and the lower side of the step surface 11D is slightly above the upper side. It is depressed.

  As shown in FIG. 4, a plurality of (for example, four) connecting ribs 35 protrude from the lower surface of the mounting wall 14 and extend in the first horizontal direction H <b> 1 to communicate between the groove side walls 24 and 24. Two of the connecting ribs 35 are arranged in the same plane as the partition wall 31, and the remaining connecting ribs 35 are formed on the bottom walls 25, 25 at positions near both lateral ends of the first side wall 11. It is arranged above. The lower surfaces of the plurality of communication ribs 35 are flush with the partition wall 31 and the lower surface. The upper surface of the partition wall 31 is flush with the upper surfaces 11B and 12B of the first side wall 11 and the second side wall 12.

  As shown on the left side of FIG. 8, two pairs of first alignment ribs 32 and a pair of second alignment ribs 33 are formed in the weight receiving groove 30 so as to face each other for each divided groove 30 </ b> A. Yes. Specifically, the first alignment ribs 32 are formed on the first side wall 11 and the groove side wall 24 at positions near both ends in the longitudinal direction of each division groove 30A, and are opposed to each other in the width direction of the division groove 30A. . On the other hand, the second alignment rib 33 is formed on the facing surface between the groove end wall 26 and the partition wall 31 or the facing surface between the partition walls 31 and 31, and faces the longitudinal direction of the dividing groove 30 </ b> A.

  As shown in FIG. 5, each first alignment rib 32 extends from the upper end of the notch 27 to a position near the upper ends of the first side wall 11 and the groove side wall 24. The second alignment rib 33 extends from the lower end of the groove end wall 26 and the partition wall 31 to a position closer to the upper end. Further, the protruding amounts of the first and second alignment ribs 32 and 33 gradually decrease from the midway position in the vertical direction toward the upper end. Note that the upper end of the second alignment rib 33 is positioned slightly above the upper end of the first alignment rib 32.

  FIG. 1 shows an example of a weight 90 accommodated for each divided groove 30A. The weight 90 is a rectangular metal plate and fits exactly in each divided groove 30A as shown on the right side of FIG. At that time, the weight 90 slides into contact with the first and second approaching ribs 32 and 33 and smoothly moves to the bottom of the dividing groove 30A. Further, as shown in FIG. 7, when the weight 90 is inserted to the bottom of the dividing groove 30A, the upper end position is supported by the first and second alignment ribs 32 and 33, and therefore the dividing groove 30A. It becomes difficult to jump out from.

  The weight 90 can be easily manufactured by cutting, for example, a sheet metal such as iron, stainless steel, aluminum, brass, or tungsten having a width and a thickness according to the Japanese Industrial Standard (JIS). .

  This is the end of the description of the configuration of the transport device 10 of the present embodiment. Hereinafter, the effect of this conveying instrument 10 is demonstrated. The transport device 10 is used in a state where the weight 90 is housed in the weight housing groove 30. For example, a plurality of industrial products are placed on the placement wall 14 as luggage. Then, for example, a plurality of transfer devices 10 are stacked on a moving table of a cleaning device (not shown). At this time, the upper surface protrusion 12C and the upper surface protrusion 11C of the lower conveyance device 10 are fitted inside the upper conveyance device 10 to prevent lateral displacement of the upper and lower conveyance devices 10, 10.

  The moving table of the cleaning apparatus descends into the cleaning liquid in the cleaning tank together with the plurality of transporting apparatuses 10 stacked. Then, the air and the cleaning liquid are exchanged through the plurality of through holes 15 of the transport device 10, and the plurality of transport devices 10 are immersed in the cleaning liquid. At this time, the transport device 10 receives air buoyancy, but the transport device 10 is stably immersed because the opposing sides along the pair of first side walls 11 and 11 are held by the weight 90. . When the dipping process (cleaning process) for a predetermined time is completed, the moving table is raised, the transport device 10 is taken out from the cleaning liquid, and the cleaning process is completed. At this time, the cleaning liquid in the weight housing groove 30 is discharged through the notch 27. The transporting instrument 10 that has finished the cleaning process is transported to, for example, a drying process.

  As described above, in the transport device 10 of the present embodiment, a wide range extending along a pair of opposing sides of the planar shape is stabilized by the weight 90 housed in the weight housing groove 30 and is stable in the liquid. Even if it exists, it will not move as easily as before. Thereby, an immersion process can be performed stably. Moreover, since the weight accommodation groove | channel 30 has opened the upper surface, the weight 90 can be inserted / extracted easily. Thereby, for example, the operation of reusing the weight 90 and replacing the transport device 10 with a new one, or the operation of removing the weight 90 from the weight receiving groove 30 of the transport device 10 that is not used for the dipping process are easily performed. be able to. At that time, the weight 90 may be pushed up through the notch 27 and removed from the weight housing groove 30.

  Further, when the weight 90 is housed in the weight housing groove 30, the position near the upper end is supported by the first and second approaching ribs 32, 33. It is possible to prevent the weight 90 from jumping out from the play and the weight housing groove 30.

  Further, the partition wall 31 can suppress deformation such that the opposing surfaces of the weight receiving groove 30 approach or separate from each other. In addition, as shown in FIG. 4, the partition walls 31, 31 of the both weight receiving grooves 30, 30 are arranged in the same plane, and the both weight receiving grooves 30, 30 are formed in the same plane as the partition walls 31, 31. Since the communication rib 35 that communicates between the groove side walls 24 and 24 is disposed, the partition wall 31 and the communication rib 35 are integrated to reinforce the entire conveying device 10.
