Further, the starting end of the cable chain 6〇 is fixed to the center of the bracket 49 in the Y direction. Further, a cleat 50 is fixed to the vertical inspection 12B side of the bracket 49 on the extension of the first cable guide 51. Further, each of the cables concentrated in the center of the cargo bed 14 in a plan view is connected to a cable (not shown) housed in the cable 60 via the clamp 50. 322138 18 201107209 The cable chain 60 is made of resin or metal, and is formed of a plurality of connecting side sheets that are coupled to each other in a chain-like manner, and can be configured to accommodate the cables in a state of being arranged. Furthermore, the structure of the cable chain 60 is such that the electron beams are not entangled, or the arrangement of the cables does not change, and the electron beams are separated. In this embodiment, the cable is housed in the cable chain 60 to form a tight cable. One end side of the cable chain 60 is fixed to the holder 49 of the cargo bed 14 in a horizontal posture. Further, as shown in Fig. 3, the other end side of the cable chain 60 is pulled into the column 12A from an opening (not shown) provided at a substantially intermediate portion in the height direction (Z direction) of the side surface 12c of one of the uprights 12A. Inside, the column 12A is fixed near the opening. That is, the cable chain 60 is suspended on the column 12A along the side surface 12c facing the cargo bed 14. (In addition, for convenience of the following description, the cable chain 60 is referred to as a table-side fixing portion 60a, and a portion fixed to the column 12A is referred to as a column-side fixing portion 60b). The electric strip, which is led out from the winding chain 60 pulled into the column 12A, is pulled into the control panel 20 attached to the column 12A, and is routed in a predetermined manner. As shown in Fig. 6, the cable chain 60 changes its shape as the cargo bed 14 moves up and down. When the cargo bed 14 is at the uppermost stage, in the vicinity of the cargo bed side fixing portion 60a of the cable chain 60, It is a curved form that is convex upward, and is curved in a downward direction in the vicinity of the other end 60b, and the convex portion 60c that is bent downward is moved downward as the cargo bed 14 is lowered. 19 322138 201107209 In addition, the cable chain 60 has the following bending characteristics, that is, it is not possible to bend the front end side from the positive 18 degrees to the negative 180 degrees before the linear state, for example, but to determine the bendable 18 (degree) first. The direction is either one of the positive side and the negative side and on the other side, it can only be bent by, for example, 20 degrees. Furthermore, the cable chain 60 is set to have a minimum bending radius when bent, and cannot be bent with a radius of curvature below the minimum bending radius. Therefore, in the stacker crane 1, as shown in Fig. 9, the first cable chain 61' which is used and has the following bending characteristics (hereinafter referred to as the upper curved convex curve) is used. In the cable chain 6〇, from the starting end on the side of the deck side fixing portion 60a to the point A of the predetermined length, a large bending angle of the upward bending is obtained. Further, the one side of the column-side fixing portion 6 〇b is closer to the side A (that is, the side of the column 丨 2 A), and the second cable bond strip 6 2 having the following bending characteristics is used. A large bending angle to the curved shape of the lower hip convex is obtained. Further, the first cable chain 61 and the second hearing chain 62 are connected to each other at point A to form one dormant chain 6G (hereinafter, a point is referred to as a connecting portion 63). Further, the length of the first cable chain 61 is set to be shorter than the distance from the load Δ side fixing portion 60a to the side surface of the recording 12A facing the loading table 14. By setting the length 1 of the first cable chain 61 having the bending property convex toward the upper side so that the cargo bed 14 is positioned at the lowermost stage, the line chain from the cargo bed side fixing portion 6〇a to the vicinity of the domain i2A can be obtained. 60 is formed into a substantially horizontal form. In addition, the aforementioned paragraph extended from the bracket 49! The cable guide 5A is disposed on the lower side of the first twisted chain 61, and supports the portion close to the cargo bed side fixing portion 60a from the lower side in the XX cable chain 61 at 322138 20 201107209 And set. The base portion side of the first cable guide 51 is formed in a horizontal straight line, and its front end side is formed in an arc shape protruding from the upper side, and gradually descends as approaching the front end. In the first cable guide 51, the radius of curvature of the arc portion 51a on the distal end side is larger than the minimum radius of curvature of the first cable chain 61, and is accommodated in the radius of curvature set when the cable of the cable chain 61 is bent. No excessive load is added to the aforementioned cable. Further, when the cargo bed 14 is at the lowermost stage, the front end of the first cable guide 51 is set to be slightly above the upper surface of the road 3, and the first cable guide 51 and the road 3 do not interfere. Since the first cable chain 61 is supported from below by the first cable guide 51 having such a shape, it is possible to prevent the cable chain 61 from being bent at a radius of curvature of a minimum bending radius or less. Further, it is possible to prevent an excessive load from being applied to the first cable chain 61 in the vicinity of the cargo bed side fixing portion 60a of the first cable chain 61. Further, it is possible to prevent an excessive load from being applied to the cable housed in the first cable chain 61.

In order to cope with this, in the stacking crane 10, as shown in Fig. 9, the second cable guide 52 is provided in the frame 16 of the carriage 11. The second cable guide 52 is formed in a flat shape, and is disposed in a horizontal posture at a predetermined size position higher than the upper end of the rail 3. The second cable guide 52 has a connection portion 63 between the first cable chain 61 and the second cable chain 62 on the support cable chain 60 when the load carrier 14 is at the lowermost stage, and X 21 before and after the connection portion 63. 322138 201107209 Directional dimensions. When the cargo bed 14 is lowered to the lowermost stage, it is placed on the second cable guide 52 before and after the connecting portion 63 of the cable chain 60, and then the front and rear portions of the connecting portion 63 are used by the second electro-optical guide 52. The posture of the cable chain 61 and the second cable chain 62 is controlled to be horizontally linear. Further, for this reason, the length of the cable bar 60 is set in advance. That is, the second cable guide 52 can be said to be a guide for holding the cable chain 60 of the front and rear of the connecting portion 63 in a substantially horizontal posture when the cargo bed 14 is at the lowermost stage. Further, it can be said that it is a guide which guides the cable chain 6 附近 near the stage-side fixing portion 6〇a horizontally toward the column 12A when the cargo bed 14 is at the lowermost stage. By providing the second cable guide 52, when the cargo bed 14 is at the lowermost stage, interference between the cable chain 60 and the rail 3 can be prevented. Furthermore, when the cargo bed 4 is at the lowermost position, the cable chain 6 can be prevented from being dull. Therefore, the lowermost position of the cargo bed 14 can be lower. When the first cable guide 51 is provided on the cargo bed 14, and the second cable guide 51 is not placed in the carriage u so that the cargo bed 14 is positioned at the lowermost stage, the cable disposed on the lower side of the cargo bed 14 can be provided. The chain 60 avoids interference with the obstruction 3 and allows it to bend slowly and guide it to near the level near the stand 12a. Therefore, the lowermost stage of the cargo bed 14 can be set at a lower position. Further, even if the cargo bed 14 is placed close to the column 12A and the winding chain 60 is suspended along the side surface 12c of the column 12A, the stacker 10 can be miniaturized. 22 322138 201107209 Further, in Fig. 9, reference numeral 53 is provided on the frame 16 of the carriage 11 and the third cable guide 53 of the column 12A, and the third cable guide 53 is used when the cargo bed 14 is at the lowermost stage, The cable chain 60 is guided in such a manner that the mounting flange 12d of the column 12A does not interfere with the winding chain 60. According to the stacker 10 configured as described above, the distance from the column 12A to the cargo storage rack ΙΑ, 1B is the same, and the cable chain 60 is suspended along the side surface i2c of the stand 12A opposite to the cargo bed μ, so In the past, when the cable was suspended from the position where the column was eccentric, the allowable rocking width of the cable chain 60 in the Y direction was increased, and the cable chain 60 was swung in the cargo storage rack or the When 1B approaches (Y direction), the cable chain 60 does not interfere with the cargo storage rack 1 and 1B. Further, when the cable chain 60 is swung toward the traveling direction (X direction) of the carriage 11, i.e., in the direction of approaching the column 12A, the cable chain 60 abuts against the column 12A' to stop the rocking of the cable chain 6''. On the other hand, when the cable chain 60 is swung in the traveling direction of the carriage 11 (in the X direction, that is, in the direction away from the pillar 12A), the lower side of the cargo bed 14 is in a space state, and when the cable chain 60 is shaken, there is no interference, so the cable The line chain 60 does not interfere with other machines or the like. Therefore, even if the cable chain 60 is rocked in either direction, the cable chain 60 can be prevented from interfering with other surrounding parts. Further, by the cable chain 60 The cargo bed side fixing portion 60a is provided at the bottom of the cargo bed 14, and even if the cargo bed 14 is placed close to the column 12A, when the cargo bed 14 is located at the lowermost stage, the cable is guided from the cargo bed side fixing portion 60a toward the column 12A. It is also easy to ensure that the line chain 60 is bent at (4) half (four) lines than the minimum nucleus red of 23 322138 201107209. The separation between the columns 12A and 12B is small, and the device can be made small: Again, as shown in Figure 3 In the side surface of the column 12A, a fourth Wei guide (suppressing the rocking guide) that opens the column 12B side and forms a water shape is provided at intervals of the ratio of the side of the column side of the cable chain 60. ) 54. When setting another 54 In the cable chain 6〇 close to the position of the column m = ground to prevent the cable chain 60 from shaking in the Y direction. , 'In addition, the cable chain 60 0 can be freely set according to the number of pieces to be stored Therefore, there is a great advantage and it can easily adapt to the advantages of the height change crane _ specification change. In addition, in the present invention, a plurality of electric wires connected to the electric machine attached to the load are used. The means is not limited to the use of a cable bond bar. For example, a resin mold beam method may be used as a tightening means, or a plurality of cables may be bundled into a flat shape by a resin mold method to serve as a tight cable. (2) A schematic plan view of a stacking crane of another second embodiment is shown in Fig. 12. The stacking crane 100 is configured to span two rails (tracks) 3A arranged in parallel with each other, The structure of the walking mode of the 3B is formed in a rectangular frame shape from a plan view, and the wheels 117 which are rotated on the roads 3A, 3B are provided at the four corners. The Y-direction frame 116y of the frame 116 Upper, the columns 112A, U2B are vertically fixed on the inner side thereof and the detour 3 The positions of A and 3B are equidistant. The cargo bed 114 is disposed on the side of the frame 116 and the columns 112A and U2B of the carriage 111 322138 24 201107209. That is, the cargo bed 114 is not repeated with the trolley U1 from a plan view. In the stacker 100 of this embodiment, the point at which the cargo bed 114 moves up and down along the columns 112A, 112B is the same as that of the foregoing embodiment, but is configured not to overlap with the trolley 111 in a plan view. The cargo bed 114, and the roads 3A, 3B are not below the cargo bed 114, so when the cargo bed 114 moves downward, 'by moving the cargo bed 114 into the opening 111a of the trolley 111, the cargo bed 114 can be moved closer. The position of the floor surface of the rails 3A, 3B is laid. In the stacker 100, the cargo bed side fixing portion of the winding chain is disposed at the bottom of the cargo bed 114, and the wire chain is along the side of the column 112α and the cargo bed 114, as in the foregoing embodiment. When the side surface 112c is suspended, when the loading platform 4 is moved to the lowermost stage, the interference between the carrier 114 and the track line bar 6Q and the tracks 3A, 3B can be avoided, so that the lowermost stage of the cargo bed 114 can be further reduced. s position. [Industrial Applicability] Further, the present invention is not limited to the foregoing embodiments. For example, the track traveling trolley provided with the lifting mechanism is not limited to the stacking type crane, and can be applied to other types of conveying devices that are not classified in the stacking type lifting machine, and is a trolley that transports the goods in the vertical direction and the horizontal direction. Therefore, according to the configuration of the present invention, in the trolley which is not classified in the other transporting apparatus of the stacker crane, even if the cable is shaken in either direction, the interference of the cable harness with other surrounding machines can be prevented. Furthermore, the size of the two vertical turns can be shortened, and the device can be miniaturized. Also, 322138 25 201107209 does not apply excessive bending loads to the tight cable. Furthermore, the position of the lowermost section of the cargo bed can be lowered. Further, it is possible to surely prevent the tight cable from being swung in a direction orthogonal to the traveling direction of the above-described trolley. Further, the chain of the line from the fixed portion to the vicinity of the column can be formed into a substantially horizontal shape. In addition, it is possible to prevent the cable of the cable including the motor for driving the conveyor from interfering with the cargo receiving frame.
