As shown on the left side of FIG. 8, in the weight accommodating groove 30, two pairs of first-aligned ribs 32 and a pair of second-aligned ribs 33 are formed in a state of facing each other for each division groove 30A. There is. Specifically, the first aligned rib 32 is formed on the first side wall 11 and the groove side wall 24 at positions near both ends in the longitudinal direction of each dividing groove 30A, and faces each other in the width direction of the dividing groove 30A. .. On the other hand, the second aligned 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 each other in the longitudinal direction of the dividing groove 30A.

As shown in FIG. 5, each first gathering rib 32 extends from the upper end of the notch 27 to a position near the upper end of the first side wall 11 and the groove side wall 24. Further, 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.

The upper end of the second aligned rib 33 is located slightly above the upper end of the first aligned rib 32.

FIG. 1 shows an example of a weight 90 accommodated in each dividing groove 30A. The weight 90 is a rectangular metal plate and, as shown on the right side of FIG. 8, fits exactly in each dividing groove 30A. At that time, the weight 90 slides in contact with the first and second gathering 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 position near the upper end is supported by the first and second gathering ribs 32 and 33, so that the dividing groove 30A It becomes difficult to jump out from.

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

This concludes the description of the configuration of the transport device 10 of the present embodiment. Hereinafter, the action and effect of the transport device 10 will be described. The transport device 10 is used in a state where the weight 90 is accommodated in the weight accommodating groove 30, and for example, a plurality of industrial products are placed as luggage on the mounting wall 14. Then, for example, a plurality of transport appliances 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 transfer device 10 are fitted inside the upper transfer device 10 to prevent lateral displacement of the upper and lower transfer devices 10 and 10.

The moving table of the cleaning device descends into the cleaning liquid of the cleaning tank together with the plurality of stacked transport appliances 10. Then, the air and the cleaning liquid are replaced through the plurality of through holes 15 of the transporting instrument 10, and the plurality of transporting instruments 10 are immersed in the cleaning liquid. At this time, the transport device 10 receives the buoyancy of air, but the weight 90 presses the opposite sides along the pair of first side walls 11 and 11, so that the transport device 10 is stably immersed. .. Then, when the immersion treatment (cleaning treatment) for a predetermined time is completed, the moving table is raised and the transport device 10 is taken out from the cleaning liquid, and the cleaning treatment is completed. At this time, the cleaning liquid in the weight accommodating groove 30 is discharged through the notch 27. The transport device 10 that has been washed is transported to, for example, a drying step.

As described above, in the transport device 10 of the present embodiment, a wide range extending along a pair of opposite sides of the planar shape is pressed by the weight 90 accommodated in the weight accommodating groove 30 to be stable and stable in the liquid. Even if there is, it will not move as easily as before. As a result, the dipping process can be stably performed. Further, since the upper surface of the weight accommodating groove 30 is open, the weight 90 can be easily inserted and removed. Thereby, for example, the work of reusing the weight 90 and replacing the transporting tool 10 with a new one, the work of pulling out the weight 90 from the weight accommodating groove 30 of the transporting tool 10 not used for the dipping process, and the like can be easily performed. be able to. At that time, the weight 90 may be pushed up through the notch 27 and pulled out from the weight accommodating groove 30.

Further, when the weight 90 is accommodated in the weight accommodating groove 30, the position near the upper end is supported by the first and second gathering ribs 32 and 33, so that the weight 90 is displaced in the weight accommodating groove 30. The backlash and the weight 90 from the weight accommodating groove 30 are prevented from popping out.

Further, the partition wall 31 suppresses deformation such that the facing surfaces of the weight accommodating groove 30 approach or separate from each other. Moreover, as shown in FIG. 4, the partition walls 31 and 31 of the double weight accommodating grooves 30 and 30 are arranged in the same plane, and the double weight accommodating grooves 30 and 30 are arranged in the same plane as the partition walls 31 and 31. Since the connecting ribs 35 connecting between the groove side walls 24 and 24 are arranged, the partition wall 31 and the connecting ribs 35 are integrated to reinforce the entire transport device 10.
