Description of the Invention [Technical Fields of the Invention] The present invention relates to a vehicle width of an unmanned trolley, an unmanned trolley, and, even if it is not more than necessary, the load can be stably supported and used for large and large weights. In the case of a liquid crystal substrate manufacturer or the like, it is transported to a predetermined position in a clean room, and a plurality of sheets of the liquid crystal substrate are stacked and stored in a straight line and/or a curved line. The unmanned transport vehicle C that is driven is transported, and the transfer machine on the fixed side of the clean room is re-loaded in the processing workshop. In recent years, the number of the large-sized liquid crystal substrates and the like has increased, which inevitably has become the total weight of the large objects of the cymbal, and the entire truss is required. However, as the weight of the entire liquid crystal substrate increases, the weight of the liquid crystal substrate increases. As shown in the support side 5, only the front and rear ends of the bottom are placed on the front and rear positions of the unmanned transport trolley. Therefore, if the heavy weight is placed on the line shown in Fig. 6, the center of the bottom is shown. There is no particular mention that the rigidity of the truss is increased even if it is not increased, and the transportation trolley such as the liquid crystal substrate manufacturing factory must be transported. The conveyance machine such as a liquid crystal substrate and the storage rack are placed in a predetermined space, and are placed in a rail row provided in the clean room, and are configured to be disposed in a cleaning machine, a storage rack, and a transport table, and It is housed in a single shape and is lighter in weight. The number of nanometers increases, and the size is increased. The method is as conventional, for example, according to the weight of the entire support, the stack of the device is placed on the table.匣 Place on the table, that is, if the weight of the storage item is supported by the fifth method, -5- 200811019 (2) will bend downward. Therefore, it is difficult to stably place it on the cymbal stand, and it is stably supported at a standstill. 'The vibration of the unmanned trolley is moving or the position of the center of gravity when driving, etc., the unmanned trolley is unstable, and there is a collision due to reloading or There is a problem that the liquid crystal substrate in the crucible is broken due to vibration during running or the like. In addition, in order to prevent this, the rigidity of the truss is increased, and the total weight of the truss is increased. Further, as shown in Fig. 6, it is possible to support only the both end portions in the width direction of the crucible, and to increase the crucible support table. The length in the width direction increases the width of the unmanned trolley, which in turn increases the size of the trolley. [Problem to be Solved by the Invention] The present invention has an object of providing an unmanned transport vehicle, and it is an object of the present invention to provide a vehicle having a large size and a large weight without increasing the width of an unmanned transport vehicle. An unmanned trolley that can be transported even if the rigidity of the truss is not increased to the extent necessary. (Means for Solving the Problem) In order to achieve the above object, the unmanned transport vehicle of the present invention is rotatably mounted on the front and rear ends of the lower portion of the transporting vehicle body to be automatically driven, and is disposed on the transporting vehicle body. The upper base is provided with a cymbal stand, and constitutes an unmanned transport vehicle loaded with a support cymbal, and is characterized in that 'the cymbal loading position of the cymbal stand is set at a position that supports the front and rear ends of the bottom of the cymbal and the central portion therebetween. In this case, the placement position of the cymbal stand can be a position where the -6 - 200811019 (3) extension fork of the transfer machine is inserted under the bottom of the cymbal, and the insertion position is not hindered. (Effect of the Invention) According to the present invention, the slewing seat that can be automatically driven by being attached to the front and rear ends of the lower portion of the transporting vehicle body is rotatably mounted, and is disposed on the pedestal disposed on the upper portion of the transporting vehicle body.匣 Placement table, in the unmanned trolley that constitutes the loading support ,, by setting the 匣 loading position of the 匣 placement table to the position of the front and rear ends of the 匣 bottom and the center of the middle of the 匣, the average of the bottom surface of the 亘匣Support, so it is not necessary to increase the rigidity of the truss to the extent necessary, and even if it is large and heavy, it can be stably loaded and supported on the unmanned trolley. In addition, in the unmanned transport vehicle, the placement position of the cymbal stand is such that when the extension fork of the transfer machine is inserted under the bottom of the cymbal, the position where the insertion is not hindered can be prevented, even if the intermediate portion of the bottom surface of the cymbal is supported. It is true that the reprinting of the cockroach is done automatically. [Embodiment] (Best Mode for Carrying Out the Invention) Hereinafter, an embodiment of the unmanned transport vehicle of the present invention will be described based on the drawings. (Embodiment 1) An embodiment of the unmanned trolley of the present invention is shown in Figs. 1 to 4 . The tracked unmanned transport trolley C, which can be driven in a straight line or in a curve, can be transported along the pavement 200811019 (4) on the fixed side of the traveling rail R, R, from: the swing seat 1, 1 , which is driven by the unmanned trolley C Each of the front and rear positions of the direction is provided with one seat; the transporting vehicle body 2 is rotatably mounted via the turning shafts 3, 3, respectively, at the lower position of the transporting carriage body 2; the bases 4, 4 and the center a base 40, each of the bases 4 and 4 is disposed at a front and rear position of the upper traveling direction of the transporting carriage body 2, and the central base 40 is disposed at an intermediate position of the bases 4, 4; a stacking table (the center placing table) 50 fixed to the upper surface portion of the base 4, the stacking table (the center placing table) 50 being fixed to the upper surface of the center base 40; the traveling wheel W And W and guide rollers G and G are provided in each of the revolving seats 1, 1 , and the traveling wheels W and W roll on the rails (hereinafter referred to as traveling rails) R and R, and the guide rollers G and G travel along the road. The rails R and R guide the driving; and the picking coil 6 is protruded from the swinging seat 1 and can be powered by the contactless power supply. Moreover, the load of the 匣K (transported object) placed on the transporting carriage main body 2 is supported between the two slewing seats 1 and 1 which are rotatably attached to the front and rear positions of the lower side of the transporting carriage main body 2 via the rotating shaft 3, and is appropriately It is determined that the guide rollers G and G are protruded from one side end surface of each of the revolving seats 1 so as to be steadily arranged along the straight path and the curved path, thereby being arranged to be in contact with the side surface of the traveling rail R, even if In the curved path, the gyro seat 1 can still smoothly sway along the curved path to drive stably. Further, the pickup coil 6 is protruded from the side opposite to the protruding side of the guide roller G, and can be supplied in a non-contact manner. Arranged at the intermediate position of the front and rear bases 4, 4 and disposed on the transport carriage -8 - 200811019 (5) The central base 40 of the upper portion of the main body 2 is set such that the transfer base is formed between the central base 40 and the base. The telescopic fork is inserted into the space 1 0. Further, the cymbal placement table 5 disposed on the upper surface of the susceptor 4 and the cymbal placement table (匣 center placement table) 50 disposed on the upper surface of the center pedestal 40 support the bottom and front of the 匣K at three points in the central portion. The position, even if it is a large weight, prevents deformation of the center of the center of the crucible and is safely loaded on the unmanned trolley C, that is, on the table 5, 50. Thereby, the length of the unmanned transport carriage C in the width direction of the stacking tables 5 and 50 can be set smaller than the width of the 匣K, and the width of the unmanned transport carriage C can be set smaller than the width of the 匣K. Next, the action of the unmanned trolley of the present invention will be described. In order to load the 匣K on the unmanned transport vehicle C, if the 匣K is supported on the telescopic transfer arm a at the front end of the transfer machine (not shown), the transfer arm a is extended to the unmanned transport vehicle C side, and the front end of the transfer arm a is extended. That is, as shown in Fig. 1, the insertion is formed in the space 1 间 between the susceptor 4 and the center pedestal 40 disposed at the intermediate position, and if the transfer arm a is subsequently lowered slightly, it is supported on the transfer arm a.匣K is a cymbal placement table 5 on which the bottom surface of the front and rear portions and the bottom surface of the central portion are placed on the upper surface portion of the susceptor 4, and a cymbal placement table (center placement table) fixed to the upper surface portion of the center pedestal 40. The state on it is reproduced. In this state, the telescopic transfer arm a is retracted from the space 10 formed between the base 4 and the center base 40. Further, in this case, when the 匣K is enlarged, the 匣 placement table disposed at the intermediate position of the cymbal placement tables 5 and 5 of the susceptors 4 and 4 can be added (匣中-9 - 200811019 (6) For the number of 50, for example, two 匣 placement tables (匣 central placement table) 50 can be arranged. Further, even in this case, the telescopic transfer arm a is inserted into the space formed between the adjacent placement table 5 and the center placement table 50. Therefore, even if it is a large cymbal, it can be supported by at least three points of the bottom end portion of the front and rear positions of the traveling direction and the central portion of the bottom surface at the intermediate position, so that the rigidity of the truss does not have to be more than necessary, and stable support is possible. In order to reduce the weight of the truss, and to increase the width of the unmanned trolley, the 匣K can be stably loaded on the unmanned trolley C, and the liquid crystal substrate can be prevented from being damaged by the impact during the transfer or the vibration during running. The broken accident happened before. In the above, the present invention is not limited to the configuration described in the above embodiment, and the configuration thereof can be appropriately changed without departing from the scope of the invention. (Industrial Applicability) The unmanned transport vehicle of the present invention has the characteristics that the large-sized and heavy-weight sturdy load can be stably supported by the transporting trolley even if the rigidity of the truss is not required to be large. It is used for handling unmanned trolleys that are large and heavy.
