  The turntable 13 swivels so that the energization cable 53 is guided without excess or deficiency at the edge of the elevating port 7e (right side in FIG. 2) of the turntable installation recess 7d immediately below the turntable 13. A movable cable processing device 57 that moves following the operation is installed. This cable processing device 57 is a feature of the first embodiment.

  As shown in an enlarged view in FIG. 3, the cable processing device 57 includes a long guide rail 59 made of H-shaped steel, and the base end of the guide rail 59 extends from the turning center C0 of the turntable 13 to the right side in FIG. 2. The support bracket 60 provided at the edge (right side in FIG. 2) of the elevating / lowering port 7e of the recess 7d for installing the turntable is pivotally supported by the pivot shaft 61 so as to be horizontally swingable. One guide moving body 63 on the distal end side and three follower moving bodies 65 on the proximal end side with respect to the guide moving body 63 are attached to the guide rail 59 movably along the guide rail 59. By means of the leading moving body 63 and the driven moving body 65, the energizing cable 53 is held in a meandering state so as to hang down in a U-shaped loop.

  Specifically, both the leading moving body 63 and the driven moving body 65 include a rectangular frame-shaped moving member 65 that is externally fitted to the guide rail 59, as shown in an enlarged view in FIGS. Inside the moving member 65, eight vertical regulating rollers 67 that sandwich the upper horizontal wall portion 59a of the guide rail 59 from above and below, and two left and right regulation members that sandwich the vertical wall portion 59b of the guide rail 59 from the side. Each of the rollers 69 is attached to be freely rotatable.

  A support plate 71 is attached to the lower surface of the outer side of the moving member 65, and the middle portion of the two energization cables 53 is fixed to the support plate 71 by a fastener 73, and the energization cable 53 is attached to the lower end of the fastener 73. A semicircular guide plate 75 for guiding in an inverted U shape is attached. The moving member 65 of the leading moving body 63 is formed longer than the moving member 65 of the driven moving body 65 on the base end side of the guide rail 59, and a rod 77 is suspended in the middle of the moving member 65. A semicircular guide plate 75 and a fastener 73 are attached to fix the hanging portion of the energizing cable 53.

  A support plate 71 having a fastener 73 and a guide plate 75 similar to those of the leading moving body 63 and the driven moving body 65 is fixed to the proximal end side of the guide rail 59. The current-carrying cable 53 between the adjacent support plates 71 is curved in a U shape, and the lower end of the current-carrying cable 53 is also restrained between the cables by the fasteners 73 to prevent the drooping portion from being twisted.

  Adjacent support plates 71 are connected by a chain 79. The length of the chain 79 is shorter than the sagging amount of the energizing cable 53, and even if the moving member 65 and the follower moving body 65 move to the distal end side of the guide rail 59 and the chain 79 is stretched in a straight line, the energizing cable 53 has a margin. Is hanging down. This is a so-called curtain system.

  The moving member 65 is coupled to a bearing member 81 fixed to a fixing bracket 80 at a position off the turning center C0 on the back side of the turntable 13 by inserting a shaft 83 rotatably. A guide member 85 that is curved and extends upward is attached to the support plate 71 of the leading moving body 63, and the energizing cable 53 is guided to the upper relay controller 49 by the guide member 85.

  Although not shown, the guide member 85 includes a bearing, and a bush and a protective material are interposed between the bearing and the energizing cable 53 to secure the energizing cable 53, and the turntable 13 rotates. The current-carrying cable 53 is prevented from moving in the longitudinal direction between the relay controller 49 by devising to increase the twisting length of the current-carrying cable 53 (decreasing the twisting angle per unit length). . Moreover, in FIG. 3, the energization cable 53 is displayed as one for convenience.

  As shown in FIG. 6, the cable processing device 57 configured as described above is configured so that the guide rail 59 is turned on during the normal time when the turntable 13 is not turning, that is, until the unloading vehicle V rises to the loading / unloading section 7. At a position deviating from the turning center C0 of 13 is disposed along the long side of the elevating opening 7e of the recess 7d for installing the turntable, and is retracted so as not to interfere with the vehicle V. At this stage, the leading moving body 63 and the driven moving body 65 are close to each other on the base end side of the guide rail 59, and the drooping amount of the chain 79 and the energizing cable 53 is large (see the solid line in FIG. 3).

  When the unloading vehicle V stops at the loading / unloading unit 7 and is lifted and supported by the pallet lifting device 43 and separated from the lifting lift 37, as shown in FIG. 7, the turntable 13 is turned around the turning center C0 in the horizontal plane. Then, the vehicle is turned 180 ° counterclockwise, the unloading vehicle V is turned 180 ° from the state shown in FIG. 6, and the driver's seat is directed toward the doorway 7b. At this time, the guide rail 59 follows the turning motion of the turntable 13 and swings in the horizontal plane counterclockwise by approximately 45 ° around the pivot shaft 61 as a fulcrum, and the leading moving body 63 and the driven moving body. As 65 moves along the guide rail 59, the energizing cable 53 is expanded and contracted in the area of the guide rail 59 and guided while changing the amount of sag. In this process, the leading moving body 63 and the driven moving body 65 move toward the distal end side along the guide rail 59 and are separated from each other, and accordingly, the chain 79 is stretched in a straight line and the dripping amount of the energizing cable 53 is reduced ( (See FIG. 3 imaginary line). When the direction of the vehicle V is changed in this way, the door 9 of the doorway 7b is opened, the user enters the loading / unloading unit 7, gets on the vehicle V, advances by forward driving, and the door 9 closes to complete a series of shipping operations. .

  As described above, in the first embodiment, the cable processing device 57 is installed in the turntable installation recess 7d immediately below the turntable 13, and the space behind the turntable 13 that has been a dead space so far is effective as the cable housing space. Since it is used, it is not necessary to separately provide a cable housing space as in Patent Document 1 to the side of the concave portion 7d for installing the turntable, and the construction cost can be reduced by that much, and the cable processing device 57 can be used. It is possible to provide the existing cable processing device 57 in a short time and at a low cost without any other construction work just by additionally installing it.

  In addition, since the cable processing device 57 of the first embodiment is a mechanism that completely follows the turning operation of the turntable 13, a dedicated drive source is unnecessary, and the simple structure and the cost can be reduced accordingly. it can.

In this state, the leading moving body 63 has moved to the forefront of the guide rail 59, and accordingly, the driven moving body 65 has also moved greatly to the tip end side of the guide rail 59, and between the adjacent moving bodies 63, 65. The interval is larger than that in the first embodiment.

  The modification 2 is a 90 ° entry type in which the entrance / exit 7b faces the long side on the right side in FIG. 9 of the elevator port 7e contrary to the modification 1, and the direction in which the driver's seat of the exit vehicle V faces the entrance / exit 7b side. The state after conversion is completed (corresponding to FIG. 7). In this state, the leading moving body 63 comes closest to the proximal end side of the guide rail 59, and accordingly, the driven moving body 65 also approaches the proximal end side of the guide rail 59, and the interval between the adjacent moving bodies 63 and 65 is increased. It is the smallest.
