However, in the storage of Patent Documents 1 and 2, the access robot is configured to carry the cassette into the racks disposed on both sides of the access machine, and therefore must have a rotation function of at least 180° (in the configuration of Fig. 9) Rotating platform 22). For example, when the object to be conveyed is a glass substrate for a liquid crystal display device, since the weight of the object to be conveyed is several hundred kilograms or more, a large driving torque is required when the robot rotates. Therefore, in order to achieve this, the drive source is increased in size and weight, and the access machine is simplified and lighter.

Further, with the increase in size and weight of the device, the operating speed of the device is also easily passivated, and in order to avoid such a situation, it is necessary to further enhance the driving force. Therefore, the driving source is further confined to a large size and a high weight. Therefore, under the enlargement of the device generated by the development of the conventional technology, the reduction in the efficiency of the device operation cannot be avoided.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a storage device that can avoid large-scale and high-weight accessors when transporting cassettes such as large-sized liquid crystal substrates, and has high transfer speed and high work. effectiveness.

The problem to be solved by the present invention is as described above, and the means for solving the problem and the effects thereof will be described next.

According to a first aspect of the present invention, a storage having the following configuration is provided. That is, the storage rack having a plurality of objects to be transported is arranged in the vertical direction and the horizontal direction, and is provided with a rail which is placed in parallel with the storage rack, and the access machine is movable on the rail; And the entrance and exit, which is used to store and transport the goods to and from the warehouse. The access device includes: a transfer device, a platform that can be lifted and lowered in a vertical direction, and a linear slide fork that is disposed on the platform and can move forward and backward in a state opposite to the storage rack; and a roller type The conveyor belt receives the conveyed object from the transfer means and delivers the conveyance to the entrance.

In the transfer device of the access machine, the linear sliding fork is used, and the rotation function is omitted, whereby the miniaturization and weight reduction can be achieved, and the operation can be performed briskly, and the time for entering and leaving the warehouse can be shortened. Moreover, even when the entrance and exit are disposed on the opposite side of the storage rack, the object to be conveyed can be delivered by the roller conveyor and the entrance and exit. Therefore, it is possible to exert an effect substantially equivalent to the transfer means having the rotation function as shown in Patent Document 1.

In the above-described storage, it is preferable that the transfer means of the access machine is configured to lower the object placement surface of the linear slide fork to a position lower than the roller upper surface of the roller conveyor.

According to this configuration, since the roller conveyor can receive the conveyed object simply by lowering the transfer means, a simpler configuration can be realized. Further, since the object to be transported can be quickly transferred from the transfer means to the roller conveyor, the time required for the conveyed material to enter and exit the warehouse can be further shortened.

According to a second aspect of the present invention, a storage having the following configuration is provided. That is, the storage rack having a plurality of objects to be transported is arranged in the vertical direction and the horizontal direction, and is provided with a rail which is laid in parallel with the storage rack, and a plurality of access machines are movable on the rail And the entrance and exit, used to carry out the storage of the goods to and from the warehouse. The track is laid so as to form a plurality of moving paths that are parallel to each other and adjacent to each other, and the plurality of access machines are movable independently of each other on each moving path. The storage rack is disposed on both sides of the plurality of movement paths. Each of the access machines includes a transfer means, a platform that can be lifted and lowered in a vertical direction, and a linear slide fork that can be moved forward and backward in a state of being opposed to the storage rack, and a roller The conveyance belt receives the conveyed object from the transfer means and delivers the conveyance to the inlet and outlet. The linear slide fork of the access machine that moves on one of the above-described moving paths is arranged in a direction opposite to the arrangement direction of the linear slide fork of the access machine that moves on the moving path adjacent thereto.

In the transfer device of the access device configured as described above, the linear sliding fork is also used, and the rotation function is omitted, whereby the device can be reduced in size and weight, and the device can be operated lightly, and the loading and unloading operation can be shortened. time. Moreover, even when the entrance and exit are disposed on the opposite side of the storage rack, the object to be conveyed can be delivered by the roller conveyor and the entrance and exit. It can also provide warehousing with high storage capacity, short working time for entering and leaving the warehouse, and low equipment cost.

In the above storage, it is preferable that the transfer means of the access machine is configured to lower the object placement surface of the linear slide fork to a position lower than the roller upper surface of the roller conveyor.

According to this configuration, since the roller conveyor can receive the conveyed object simply by lowering the transfer means, a simpler configuration can be realized. Further, since the object to be transported can be quickly transferred from the transfer means to the roller conveyor, the time required for the conveyed material to enter and exit the warehouse can be further shortened.

Embodiments of the present invention will be described below. Fig. 1 is a top perspective view showing the overall configuration of a storage container according to an embodiment of the present invention, and Fig. 2 is a side cross-sectional view showing an essential part of the operation of a roller conveyor of an access machine.

In Fig. 1, the storage 6 of the present embodiment is provided with a rack main body 7 of a storage rack, an access machine 5, a conveyor port (inlet and exit) 17 and a rail 28; as a main configuration. The frame body 7 is disposed on one side of the rail 28, and the conveyor belt inlet and outlet 17 is disposed at a position opposite to each other via the frame body 7 and the rail 28.

The rack main body 7 is provided with a rack 12 provided with a notch 38, and a storage outer wall 15; a plurality of cassettes (conveyed objects) 35 can be arranged in a vertical direction and a horizontal direction for storage.

The rail 28 is configured such that two of the two are laid in parallel with the frame body 7, and one of the access machines 5 is movable on the rail 28. The access machine 5 is provided with a transfer means 36, a conveyor belt platform (roller type conveyor) 34, a support 37, and a wheel 29; as a main configuration.

Further, the conveyor entrance/exit 17 is provided for the entrance and exit of the cassette 35 to the storage 6, and includes an entrance frame 13 and a roller 16. A plurality of rollers 16 are disposed at appropriate intervals, and are driven by a motor (not shown).

The transfer means 36 includes a lifting frame (platform) 32, a linear sliding fork 33, and a platform lifting and lowering means 26. The lifting frame 32 is configured to be vertically movable in the vertical direction by the platform lifting and lowering means 26. The linear slide fork 33 is provided on the above-described lifting frame 32, and at the same time, the storage rack (frame body 7) can be protruded and elongated and can be retracted. Further, since the linear slide fork 33 is provided so as not to be rotatable relative to the lift frame 32, it cannot be moved in and out of the frame body 7. On the upper surface of the front end portion of the linear slide fork 33, a mounting surface on which the cassette 35 can be placed is formed.

Further, a conveyor table 34 is a conveyor belt frame 31 for receiving the cassette 35 from the transfer unit 36 and delivering it to the conveyor inlet/outlet port 17, and is provided with an open-shaped conveyor belt frame 31. The lower portion of the machine 5; and a plurality of rollers 30 are rotatably supported by the conveyor belt frame 31. The height of the upper surface of the roller 30 is set to coincide with the height of the roller 16 above the conveyor inlet and outlet port 17. The roller 30 can be driven by a motor (not shown), and the cassette 35 placed on the roller 30 can be in the retracting direction of the linear sliding fork 33 (in other words, the retracting direction of the linear sliding fork 33). Transfer.

The conveyor belt platform 34 is configured to have no interference with respect to the above-described lifting frame 32 and the linear sliding fork 33. That is, at the side wall portion of the conveyor belt frame 31 of the conveyor belt platform 34, a gap portion that can accommodate the frame-like lifting frame 32 is formed, and a space for accommodating the linear sliding fork 33 is formed between the side wall portions. .

Next, the function of the conveyor belt platform 34 in the access machine 5 will be described using Figs. In addition, in each of FIGS. 3 to 6, (A) shows a front view, and (B) shows a side cross-sectional view.

Fig. 3 shows a state in which the cassette 35 is taken out of the rack 12, and then the linear slide fork 33 is intended to be retracted. When the linear slide fork 33 is retracted, as shown in FIG. 4, the cassette 35 and the linear slide fork 33 are positioned directly above the lift frame 32. Next, the access machine 5 causes the platform lifting and lowering means 26 to actuate to lower the lifting frame 32. Since the lifting frame 32 and the linear sliding fork 33 do not interfere with the conveyor belt platform 34 as described above, the lifting frame 32 is drilled into the conveyor belt platform 34 from above, and can invade and descend to the lower portion of the conveyor belt platform 34 (strictly speaking , is the inside of the above conveyor belt frame 31).

When the linear slide fork 33 intrudes in the state in which the cassette 35 is mounted and descends to the lower portion of the conveyor belt platform 34, as shown in FIG. 5, the cassette 35 is held by the roller 30 of the conveyor belt platform 34, and remains in the Roller 30. Next, the conveyor belt platform 34 rotationally drives the rollers 30 supported on the conveyor belt frame 31, and conveys the cassettes to the conveyor belt entrances and exits 17 (Figs. 6 and 2) which are adjacent to the conveyor belt platform 34. When the cassette 35 is transferred outside the lifting operation area of the conveyor platform 34, the conveyor platform 34 is freely movable.

Further, the storage 6 of the plan view shown in FIG. 7 has substantially the same configuration as that of FIG. 1, and differs from FIG. 1 in that a plurality of (3) access machines 5 are provided on the common track 28, and In addition to the conveyor entrance and exit 17, there are three inline ports 18 that abut the frame body 7. The in-line entrance/exit 18 is an entrance and exit used when the liquid crystal manufacturing apparatus 8 directly performs the loading and unloading of the cassette 6 into the storage.

The in-line inlet and outlet 18 is provided on the same side as the rack main body 7, and is connected to the cassette 35 between the accessing machines 5, and is carried out by the linear sliding fork 33 of the transfer means 36. For example, if the notch 38 is provided in the in-line entrance and exit 18 like the above-described rack 12, the cassette 35 can be transferred between the linear slide fork 33 and the in-line entrance 18. Further, the in-line inlet and outlet 18 of the liquid crystal manufacturing apparatus 8 is an inlet and outlet for connecting the storage 6 and the liquid crystal manufacturing apparatus 8, and may be directly connected by a roller conveyor or connected by a transfer robot.

Next, the loading and unloading operations of the cassette 35 implemented by the storage rack 6 of the storage rack shown in Figs. 1 and 7 will be described.

In the following, the accommodating operation will be described. First, the cassette 35, which is transported by another transport means such as an unmanned transfer cart or a lifter (not shown), is placed on the conveyor entrance 17 shown in FIG. Then, the access machine 5 is moved to the opposite position of the conveyor entrance and exit 17 to stop, and the elevating frame 32 is lowered to the lower limit of the lifting range. At this time, as shown in FIG. 2, the height above the roller 16 of the conveyor belt inlet and outlet 17 slightly coincides with the height above the roller 30 of the conveyor belt platform 34.

Immediately thereafter, the rollers 16 of the conveyor belt inlet and outlet 17 and the rollers 30 of the conveyor belt platform 34 of the access machine 5 are driven, and the cassettes placed on the conveyor belt inlet and outlet 17 are transferred to the conveyor belt platform of the access machine 5. 34. The completion of the transfer is detected by an analytic sensor mounted on the conveyor platform 34, by which the cassette 35 is properly positioned on the conveyor platform 34.

Immediately thereafter, the access machine 5 raises the elevating frame 32 from the lower limit position. At this time, the cassette 35 placed on the conveyor belt platform 34 is held by the linear slide fork 33 which is integrally raised with the elevating frame 32. Thereafter, the access machine 5 moves horizontally along the rack 12 on the rail 28, and at the same time, the elevating frame 32 is raised, and the transfer means 36 is stopped in a state in which the transfer rack 36 is oriented toward the intended rack position.

After the access machine 5 is stopped, the transfer means 36 extends the fork to the loading position of the rack 12 while maintaining the loading of the cassette 35 in the state of the linear slide fork 33, and at the same time the front end of the fork (ie, the cassette 35) Matching. Next, when the lifting frame 32 is lowered by a small amount, the front end of the fork passes downward through the notch 38, and the front end of the fork is lower than the frame surface, and the cassette 35 is held by the rack 12 and remains on the rack 12. . The storage of the cassette 35 into the magazine 6 is completed in the above manner, and then the access machine 5 retracts the fork of the linear slide fork 33 to advance the next operation.

The following describes the delivery operation, which is performed in the exact opposite of the above-described storage operation. First, the access machine 5 moves the transfer means 36 to the rack position in which the target cassette 35 is accommodated, and after the linear slide fork 33 comes in and out, the front end of the linear slide fork 33 passes through the notch 38 from the bottom to the top. In a manner, the lifting frame 32 is raised a little, and the cassette 35 is picked 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 pulled into the inside of the access machine 5, and moved to the position of the conveyor entrance/outlet 17.

During the movement to the conveyor entrance 17 , the access machine 5 lowers the lifting frame 32. After reaching the conveyor entrance 17 , the lifting frame 32 is lowered further below the conveyor platform 34 , so that the cassette 35 is transported from the conveyor. 17 undertake (Figure 5). Next, the rollers 30, 16 of the conveyor belt platform 34 and the conveyor inlet and outlet 17 are driven, and the cassettes 35 are transferred from the conveyor belt platform 34 to the conveyor inlet and outlet (Fig. 6). The cassette 35 placed on the conveyor entrance/outlet 17 is placed on a transporting cart or the like and carried out to the outside.

Further, the series of transfer operations are performed based on command signals from a control device such as an MCS that controls production management and a MES that manages the transfer system. In addition, the controller of the offline storage 6 can also issue the same command signal.

As described above, the storage unit 6 of the present embodiment includes a plurality of rack main bodies 7 capable of storing the cassettes 35, which are arranged in the vertical direction and the horizontal direction, and are provided with a rail 28 in parallel with the rack main body 7; The machine 5 is movable on the rail 28; and the conveyor belt inlet and outlet 17 is configured to perform the loading and unloading of the cassette 35 with respect to the storage 6. Further, the access machine 5 includes a transfer mechanism 36 including a lift frame 32 that can be lifted and lowered in the vertical direction, and a state in which the lift frame 32 is provided on the lift frame 32 so as to be opposite to the frame body 7. A linear sliding fork 33 that can move forward and backward; and a conveyor platform 34 from which the cassette 35 can be received and delivered to the conveyor inlet and outlet 17.

As described above, the linear sliding fork 33 is used in the transfer means 36 of the access machine 5, and the rotation function is omitted, so that the size and weight can be reduced, and the movement can be performed lightly, and the time for entering and leaving the warehouse can be shortened. This effect is particularly exerted when the cassette 35 is of high weight. Further, as shown in FIG. 1 or FIG. 7, even when the conveyance belt entrance/exit 17 is disposed on the side opposite to the rack main body 7, the cassette 35 can be transferred by the conveyance belt platform 34 and the conveyance belt entrance/exit 17. Therefore, it is possible to achieve substantially the same effect as the transfer method having the rotation function as shown in Patent Document 1 or the like.

Further, in the above-described storage 6, the transfer means 36 of the access machine 5 is configured to lower the upper end surface (the cassette mounting surface) of the linear slide fork 33 to be lower than the roller 30 of the above-mentioned conveyor belt platform 34. The location.

Thereby, since the belt platform 34 can be received by the cassette 35 simply by lowering the elevating frame 32, a simpler configuration can be realized. Further, the cassette 35 can be quickly transferred from the transfer means 36 to the conveyor belt platform 34, so that the time required for the cassette 35 to be taken out can be further shortened. At the time of storage, the cassette 35 can be transferred from the conveyor platform 34 to the transfer means 36 only by raising the lift frame 32 from the lower limit position. Therefore, the time required for storage can of course be shortened.

In addition, FIG. 8 shows a modification in which the storage 6 is configured such that two storages of FIG. 7 are arranged opposite each other. In the storage 6 of Fig. 8, the rails 48 and the rails 47 are separated by the conveyor entrances and exits 17 and arranged on a straight line, which are laid parallel to the rails 28, respectively. The spacing between the track 48 and the track 28 is the same as the spacing between the track 47 and the track 28, and the access machine 5 can move independently of each other on the tracks of the track 28, the track 47, and the track 48. Further, the rack main bodies 7a and 7b of the storage rack are disposed on both sides of the three pairs of rails so as to sandwich the three pairs of rails 28, the rails 47, and the rails 48.

For example, when the cassette body 35 is transferred from the rack body 7a on one side to the rack body 7b on the other side, the access machine 5 moving on the rail 28 takes out the cassette 35 from the predetermined rack 12, and is aligned. Stop at the conveyor inlet and outlet 17. The cassette is conveyed to the conveyor entrance/outlet 44 via the conveyor belt platform 34 of the access machine 5, the conveyor entrance/outlet 17, and the conveyor belt 45, and is delivered to the access machine 5 that moves on the rail 48. Further, when the carrier body 7b is delivered to the holder body 7a, the cassette 35 is delivered via the opposite path.

Further, when the cassette 35 is transferred from the holder body 7b opposed to the rail 48 to the holder body 7b opposed to the rail 47, the access machine 5 moving on the rail 48 takes out the card from the predetermined magazine 12.匣35. The cassette 35 is conveyed to the conveyor entrance/exit 43 via the conveyor belt platform 34 of the access machine 5, the conveyor entrance/exit 44, the conveyor belt 46, the conveyor entrance/exit 17, and the conveyor belt 45, and is transferred to the storage on the rail 47. Take the machine 5.

Then, in the access machine 5 which moves on the upper rail 28 in Fig. 8, the linear slide fork 33 of the transfer means 36 is provided to be movable in and out with respect to the upper frame body 7 in the figure, and is moved on the lower side rail 28. The linear slide fork 33 of the access machine 5 is provided to be accessible in relation to the frame body 7 on the lower side in the drawing. Straightforwardly, the linear sliding fork 33 of the access machine 5 is disposed opposite to each other in the upper side and the lower side in the drawing. Thereby, the cassette 35 can be easily transferred to the holder body 7 disposed on both sides of the rail 28.

As described above, in the storage 6 constructed as shown in Fig. 8, the rails are laid in such a manner as to constitute a plurality of moving paths which are parallel and adjacent to each other, and the plurality of accessing machines 5 are movable independently of each other on the respective moving paths. Further, the frame body 7 is disposed on both sides of the plurality of moving paths, and the linear sliding fork 33 of the accessing machine 5 that moves on one of the moving paths is disposed in a direction and a moving path adjacent thereto The linear sliding forks 33 of the access machine 5 are arranged opposite to each other.

With such a configuration, substantially the same effects as those of the configurations of Figs. 1 and 7 can be achieved, and the accommodation ability can be easily improved. In addition, the configuration of FIG. 8 is similar in function to the conventional configuration of FIG. 9. However, according to the practical experience of the inventor of the present invention, it can be confirmed that the configuration of FIG. 8 is in the size of the device, the time required to enter and exit the library, It is superior in any aspect such as equipment cost.

The above description is suitable for the embodiment and the modification of the present invention, but the above configuration is an example, and can be changed as follows, for example.

The conveyor inlet and outlet 17 may also be disposed on the same side of the frame body 7 instead of on the opposite side of the frame body 7. Further, the conveyance belt entrance/exit 17 is not limited to the case where the storage is out of the warehouse, and may be divided into an entrance for exclusive use of the storage and an entrance and exit for the delivery. Further, the object to be transported may be the FOUP or the like described above instead of the cassette 35.

The lifting frame 32 and the conveyor belt platform 34 are not limited to the shapes shown in FIG. 1 and the like, and may be more appropriately shaped. However, when the transfer means 36 and the conveyor belt platform 34 are formed in a shape that does not interfere with each other, and the transfer means 36 can be lowered below the upper surface of the rollers 30 of the conveyor belt platform 34, it is advantageous as described above.

The present invention will be described in detail with reference to the specific embodiments thereof, and various modifications and changes can be made without departing from the spirit and scope of the invention.

The present application is based on Japanese Patent Application No. 2005-334037, filed on Nov. 18, 2000, the content of which is hereby incorporated by reference.
