  However, in the stockers of Patent Documents 1 and 2, the stacker robot is configured to carry cassettes in and out of the shelves arranged on both sides of the stacker crane, and therefore must have at least a 180 ° rotation function (see FIG. In the configuration of 9, the turning table 22). For example, when the object to be conveyed is a glass substrate for a liquid crystal display device, the cassette weight of the object to be conveyed is several hundred kilometers or more, and a large driving torque is required for turning the robot. Therefore, the drive source for realizing this has become larger and heavier, which has become an obstacle to making the stacker crane compact and lightweight.

  In addition, as the equipment becomes larger and heavier, the working speed of the equipment tends to slow down. To avoid this, it is necessary to increase the driving force further, and the drive source becomes larger and heavier. Fall into. Therefore, a reduction in the operating efficiency of the apparatus is inevitable when the apparatus is enlarged due to the extension of the prior art.

  The present invention has been made in view of the above circumstances. The purpose of the present invention is to avoid an increase in the size and weight of the stacker crane and to increase the transfer speed when transporting a cassette such as a large liquid crystal substrate. It is to provide a stocker with high work efficiency.

In addition, the object to be conveyed can be quickly relayed from the transfer means to the roller conveyor, and the time required for loading and unloading the object to be conveyed can be further shortened.

  Next, embodiments of the invention will be described. FIG. 1 is an upper perspective view showing an overall configuration of a stocker according to an embodiment of the present invention, and FIG. 2 is a side sectional view of an essential part showing the operation of a roller conveyor of a stacker crane.

  In FIG. 1, the stocker 6 of the present embodiment includes a shelf main body 7 of a storage shelf, a stacker crane 5, a conveyor port (port) 17, and a rail 28 as main components. The shelf body 7 is disposed on one side of the rail 28, and the conveyor port 17 is disposed at an opposing position with the shelf body 7 and the rail 28 interposed therebetween.

  The shelf body 7 includes a shelf 12 provided with a notch 38 and a stocker outer wall 15, and can store a plurality of cassettes (conveyed objects) 35 in a vertical direction and a horizontal direction.

  Two rails 28 are laid in parallel with the shelf body 7, and one stacker crane 5 is configured to run on the rail 28. The stacker crane 5 includes transfer means 36, a conveyor table (roller conveyor) 34, a support column 37, and wheels 29 as main components.

  The conveyor port 17 is used for loading and unloading the cassette 35 with respect to the stocker 6 and includes a port frame 13 and a roller 16. A plurality of rollers 16 are arranged at appropriate intervals, and can be driven by a motor (not shown).

  The transfer means 36 includes an elevating frame (table) 32, a linear slide fork 33, and a table elevating means 26. The elevating frame 32 is configured to be vertically movable by the table elevating means 26. The linear slide fork 33 is installed on the elevating frame 32, is extended so as to protrude with respect to the storage shelf (shelf body 7), and is configured to be retractable. Since the linear slide fork 33 is installed on the lifting frame 32 so as not to turn, the linear slide fork 33 cannot be moved away from the shelf body 7. A mounting surface on which the cassette 35 can be mounted is formed on the upper surface of the tip of the linear slide fork 33.

  The conveyor table 34 is used to transfer the cassette 35 from the transfer means 36 to the conveyor port 17, and has a conveyor frame 31 that is open at the top of the stacker crane 5. And a plurality of rollers 30 rotatably supported on the conveyor frame 31. The roller 30 is provided such that the height of the upper surface thereof coincides with the height of the upper surface of the roller 16 of the conveyor port 17. The roller 30 can be driven by a motor (not shown), and the cassette 35 placed on the roller 30 is moved in a direction along the expansion and contraction of the linear slide fork 33 (more specifically, the retraction direction of the linear slide fork 33). It can be transported.

  The conveyor table 34 has a shape that does not interfere with the lifting frame 32 and the linear slide fork 33. In other words, a side wall portion of the conveyor frame 31 of the conveyor table 34 is formed with a gap portion that can receive the elevating frame 32 configured in a frame shape, and the linear slide fork 33 can be accommodated between the side wall portions. A space is formed.

  Next, the function of the conveyor table 34 in the stacker crane 5 will be described with reference to FIGS. 3 to 6, A) is a front view, and B) is a side sectional view.

  FIG. 3 shows a situation in which the cassette 35 is taken out from the shelf 12 and the linear slide fork 33 is about to be degenerated. When the linear slide fork 33 completes the retraction, the cassette 35 and the linear slide fork 33 are positioned directly above the lifting frame 32 as shown in FIG. Next, the stacker crane 5 operates the table elevating means 26 to lower the elevating frame 32. Since the elevating frame 32 and the linear slide fork 33 are configured not to interfere with the conveyor table 34 as described above, the elevating frame 32 passes through the conveyor table 34 from the top to the bottom, and the lower part of the conveyor table 34 (strictly speaking, For example, it can enter and descend to the inside of the conveyor frame 31).

  When the linear slide fork 33 enters and descends to the lower part of the conveyor table 34 with the cassette 35 mounted, the cassette 35 is scooped by the roller 30 of the conveyor table 34 and remains on the roller 30 as shown in FIG. Next, the conveyor table 34 rotationally drives the rollers 30 supported by the conveyor frame 31, and transports the cassette 35 to the conveyor port 17 facing the conveyor table 34 while being adjacent to the conveyor table 34 (FIGS. 6 and 2). When the cassette 35 is transferred out of the lifting / lowering operation area of the conveyor table 34, the conveyor table 34 can be raised and lowered.

  The stocker 6 shown in a plan view in FIG. 7 has basically the same configuration as that in FIG. 1, but a plurality of (three) stacker cranes 5 are installed on a common rail 28, and three other than the conveyor port 17 are installed. 1 in that the two inline ports 18 are provided adjacent to the shelf body 7. The inline port 18 is a port used when the liquid crystal manufacturing apparatus 8 directly enters and leaves the cassette 35 with respect to the stocker 6.

  The inline port 18 is provided on the same side as the shelf body 7, and the cassette 35 is transferred to and from the stacker crane 5 by the linear slide fork 33 of the transfer means 36. For example, if the notch 38 is provided in the inline port 18 in the same manner as the shelf 12, the cassette 35 can be delivered between the linear slide fork 33 and the inline port 18. Note that the inline port 18 of the liquid crystal manufacturing apparatus 8 is a port for connecting the stocker 6 and the liquid crystal manufacturing apparatus 8 and can be directly connected by a roller conveyor or connected via a transport robot.

  Next, the operation of loading and unloading cassettes 35 into the shelf 12 in the stocker 6 shown in FIGS. 1 and 7 will be described.

  The warehousing operation will be described. First, a cassette 35 that has been transported by an unillustrated unmanned transport cart or other transport means such as a lifter is placed on the conveyor port 17 shown in FIG. Then, the stacker crane 5 travels to the position facing the conveyor port 17 and stops, and the lifting frame 32 is lowered to the lower limit of the lifting range. At this time, as shown in FIG. 2, the height of the upper surface of the roller 16 of the conveyor port 17 and the height of the upper surface of the roller 30 of the conveyor table 34 are substantially the same.

  Subsequently, the roller 16 of the conveyor port 17 and the roller 30 of the conveyor table 34 of the stacker crane 5 are driven, and the cassette 35 placed on the conveyor port 17 is transferred onto the conveyor table 34 of the stacker crane 5. Completion of the transfer is detected by a sensor (not shown) attached to the conveyor table 34, and the cassette 35 is accurately positioned on the conveyor table 34 by this sensor.

  Next, the stacker crane 5 raises the elevating frame 32 from the lower limit position. At this time, the cassette 35 placed on the conveyor table 34 is scooped by the linear slide fork 33 that rises integrally with the elevating frame 32. Thereafter, the stacker crane 5 moves horizontally on the rail 28 along the shelf 12, raises the lifting frame 32, and stops with the transfer means 36 facing the intended shelf position.

  After stopping the stacker crane 5, the transfer means 36 extends the fork to the placement position of the shelf 12 while positioning the cassette 35 on the linear slide fork 33, and aligns the tip of the fork (that is, the cassette 35). . Next, when the elevating frame 32 is lowered by a small amount, the front end of the fork passes through the notch 38 and the top surface of the front end of the fork becomes lower than the shelf surface. At the same time, the cassette 35 is scooped by the shelf 12. It remains on the shelf 12. Thus, the storage of the cassette 35 in the stocker 6 is completed, and thereafter, the stacker crane 5 retracts the fork of the linear slide fork 33 and moves to the next operation.

  Next, the unloading operation will be described. This unloading operation is performed in the completely reverse procedure of the above-described loading operation. First, the stacker crane 5 moves the transfer means 36 to the shelf position where the target cassette 35 is accommodated, advances the linear slide fork 33, and then the tip of the linear slide fork 33 moves down the notch 38. The raising / lowering frame 32 is slightly lifted so as to pass upward, and the cassette 35 is scooped up on the mounting surface (FIG. 3). Then, the linear slide fork 33 is retracted as shown in FIG. 4 and the cassette 35 is drawn into the stacker crane 5 to travel to the conveyor port 17 position.

  While traveling to the conveyor port 17, the stacker crane 5 lowers the lifting frame 32. After reaching the conveyor port 17, the stacker crane 5 further lowers the lifting frame 32 to below the conveyor table 34 to transfer the cassette 35 to the conveyor port 17. (FIG. 5). Next, the rollers 30 and 16 of the conveyor table 34 and the conveyor port 17 are driven, and the cassette 35 is transferred from the conveyor table 34 to the conveyor port (FIG. 6). The cassette 35 placed on the conveyor port 17 is transferred to a transport cart or the like and carried out to the outside.

  Note that a series of these transfer and transfer operations are performed based on command signals from control devices such as MCS that controls production management and MES that comprehensively manages the transfer system. Further, the controller of the stocker 6 can issue a similar command signal when offline.

  As described above, the stocker 6 of the present embodiment includes the shelf body 7 that can store a plurality of cassettes 35 arranged in the vertical direction and the horizontal direction, the rail 28 laid in parallel to the shelf body 7, A stacker crane 5 capable of traveling on the rail 28 and a conveyor port 17 for loading and unloading the cassette 35 with respect to the stocker 6 are provided. The stacker crane 5 includes a transfer means 36 that includes a lifting frame 32 that can be vertically moved up and down, and a linear slide fork 33 that is installed on the lifting frame 32 and can be moved back and forth facing the shelf body 7. A conveyor table 34 that can transfer the cassette 35 from the transfer means 36 to the conveyor port 17.

  As described above, by adopting the linear slide fork 33 in the transfer means 36 of the stacker crane 5 and omitting the turning function, it can be reduced in size and weight, and can be operated easily. The time for shipping work can be reduced. This effect is particularly remarkable when the cassette 35 is heavy. Further, even when the conveyor port 17 is disposed on the opposite side of the shelf body 7 as shown in FIGS. 1 and 7, the cassette 35 can be delivered by the conveyor table 34 and the conveyor port 17. Therefore, substantially the same effect as the transfer means having a turning function as shown in Patent Document 1 can be exhibited.

  In the stocker 6, the transfer means 36 of the stacker crane 5 can lower the top surface (cassette mounting surface) of the linear slide fork 33 to a position lower than the top surface of the roller 30 of the conveyor table 34. It is configured.

  Thereby, since the cassette 35 can be inherited to the conveyor table 34 by simply lowering the elevating frame 32, a simpler configuration can be realized. In addition, the cassette 35 can be quickly relayed from the transfer means 36 to the conveyor table 34, and the time required for unloading the cassette 35 can be further shortened. In addition, since the cassette 35 can be transferred from the conveyor table 34 to the transfer means 36 only by raising the elevating frame 32 from the lower limit position at the time of warehousing, of course, the time required for warehousing is shortened.

  FIG. 8 shows a modified example, and this stocker 6 has a configuration in which two stockers in FIG. 7 are arranged to face each other. In the stocker 6 of FIG. 8, two pairs of rails 28 are laid so as to constitute a plurality of parallel and adjacent traveling paths on which the stacker crane 5 can travel independently of each other. And the shelf main body 7 of the storage shelf is disposed on both sides so as to sandwich the two pairs of rails 28. The conveyor port 17 is used, for example, to transfer the cassette 35 from the shelf body 7 on one side to the shelf body 7 on the other side.

  In the stacker crane 5 traveling on the upper rail 28 in FIG. 8, the linear slide fork 33 of the transfer means 36 is installed so as to be able to advance with respect to the upper shelf body 7 in the figure, and the lower rail The linear slide fork 33 of the stacker crane 5 traveling 28 is installed so as to be able to advance with respect to the lower shelf body 7 in the figure. In short, the arrangement direction of the linear slide fork 33 of the stacker crane 5 is reversed between the upper side and the lower side in the figure. Thereby, the cassette 35 can be easily delivered to the shelf main body 7 disposed on both sides of the rail 28.

  As described above, in the stocker 6 having the configuration shown in FIG. 8, the rails 28 are laid so as to form a plurality of parallel and adjacent traveling paths, and the plurality of stacker cranes 5 are independent of each other along the respective traveling paths. It is possible to run. The shelf body 7 is disposed on both sides of the plurality of travel routes, and travels along the travel direction adjacent to the arrangement direction of the linear slide fork 33 of the stacker crane 5 traveling on the one travel route. The arrangement direction of the linear slide fork 33 of the stacker crane 5 is opposite.

  By configuring in this way, it is possible to achieve substantially the same effect as the configuration of FIGS. 1 and 7 and to easily improve the accommodation capacity. The configuration of FIG. 8 is functionally similar to the conventional configuration of FIG. 9, but according to the knowledge of the inventor, the configuration of FIG. It has been confirmed that both the time required and the equipment cost are excellent.

  The preferred embodiment and the modification of the present invention have been described above, but the above configuration is an example, and can be modified as follows, for example.

  The conveyor port 17 can be disposed not on the side opposite to the shelf body 7 but on the same side as the shelf body 7. In addition, the conveyor port 17 is not limited to the case of serving as a loading / unloading, and can be arranged separately for a port dedicated for loading and a port dedicated for loading / unloading. Further, the above-mentioned FOUP or the like can be adopted as the conveyed object instead of the cassette 35.

  The elevating frame 32 and the conveyor table 34 are not limited to the shapes shown in FIG. However, it is advantageous as described above that the transfer means 36 and the conveyor table 34 are formed in a shape that does not interfere with each other so that the transfer means 36 can be lowered below the upper surface of the roller 30 of the conveyor table 34.
