Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an entry/exit N device used in an entry/exit lane of an automated warehouse in which articles are placed in specific cases and stored on shelves6. (Prior Art) The case used in the above-mentioned automated warehouse is provided with locked pieces that protrude downward at both the front and rear ends, and the loading/unloading device provided on the crane lifting/lowering knowledge shown in n. A case locking tool that can be raised and lowered and that can be engaged with the locked piece of the case is provided so as to be movable in the case drawing and pushing directions. On the other hand, in the above-mentioned automated warehouse, case storage shelves are usually installed on both sides of the crane travel path, and a case holder is usually installed at an appropriate location on one side of the crane travel path. .

Therefore, the loading/unloading device must be configured to be able to pull in and push out the case in either the left or right direction. For example, it is also necessary to push a case pulled out from a shelf on the right or left side onto a case holder for loading/unloading on the left or right side. In order to satisfy such requirements, the conventional storage bag T of this type is provided with a pair of case locking devices that are parallel to each other in the case pulling and pushing direction and move up and down together.

(Problems to be Solved by the Invention) In the conventional loading/unloading rfjgq as described above, the pair of case retaining tools have the function of pulling the case from the shelf on the side where each is located or the case holder for personnel retrieval. , the function is to push the case to the shelf on the same side or the case holder for loading and unloading, but in order to push out the case pulled in with the case locking tool on one side in the opposite direction, a pair of case locking devices are required. The bottom of the retracted case must be moved to the opposite side and then protruded toward the rear end of the case. Therefore, the length of the reciprocating path of the pair of case locking tools is determined by the length of the case. The length must be equal to or more than twice the length l of the pair of case locking tools, and the total length of the loading/unloading device becomes much larger than the length of the cases to be picked up.

In order to eliminate such drawbacks, it is necessary to use a belt conveyor or the like to send out the case pulled in by the case locking device in the pushing direction, which results in a significant increase in cost.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned conventional problems, and its feature is that the case can be pulled in and pushed out in either the left or right direction. a lateral movement table that is located at a lower position than the case support surface of the case holder and that is capable of reciprocating in the direction of pulling in and pushing out the case; and a lateral movement table driving means that reciprocates the lateral movement table. The lateral movement table supports two case latches arranged in parallel in the lateral movement direction so as to be able to move up and down separately, and a case latching device drive that drives both case latches individually up and down. The point is that the means have been established.

(Function) In the above-mentioned loading and unloading device of the present invention, when a case that has been pulled onto the case holder is pushed out to the opposite side using one of the case locking tools, the pair of case locking devices are moved under the pulled-in case and In order to move the stopper to the rear side of the case, you do not have to move both case fasteners to the outside of the rear end of the case, but only one of the case fasteners used for retracting can be moved to the rear end of the case. All you have to do is make it protrude outward (the other case holder is located below the case), and after pushing the case to some extent with the one case holder used for this retraction, push the case back out again. The case locking tool is moved backward, and the other case locking tool located under the case is made to protrude to the outside of the rear end of the case, and the case can be pushed out to the opposite side with this other case locking tool. .

Next, to explain how to use and function, when performing unloading work to unload a specific case 1 stored in the three-dimensional shelf 3 onto the case holder 12 for loading and unloading, the crane 6
The loading and unloading device 9
is moved to a position connected to the retrieval target position of the three-dimensional shelf 3. Then, in order to move the lateral movement table 15 closer to the case 1 to be delivered, the drive chino 23 is rotated by the motor 16 of the lateral movement table driving means 16.

When the lateral movement table 15 reaches the stroke limit position A on the shelf side (hereinafter referred to as the left side) as shown in FIG. In order to raise the stop 25 from the lower limit position to the upper limit position,
operating the motor 36 of the case locking device driving means 31;
As described above, the driving rotary body 37 is rotated by a certain angle in the normal rotation direction. As the case locking tool 25 rises, if the tip of the case locking tool 25 (roller 25a in FIG. 6) engages with the right side locked piece 2a of the case 1 as shown in FIG. As shown by the imaginary line in FIG. 9, the horizontal motion table 15 is
That is, the case 1 in the case storage section 4 of the three-dimensional shelf 3 is moved laterally to the right by the horizontal sender drive means 16 to a position B near the travel limit on the right side, and the case 1 in the case storage section 4 of the three-dimensional shelf 3 is moved to the right side by the case locking tool 25 at the upper limit position of the loading/unloading device 9. Pull the case to the left pull-out position C on the case holder 14.

As described above, the case 1 is placed on the case holder 14 of the loading/unloading B'W'' device 9 on the elevating/lowering carriage 8 of the crane 6.
Once pulled upward, the loading/unloading device 9 is moved to a position where it is connected to the loading/unloading case holder 12 by the movement of the crane 6 and the lifting/lowering of the elevating carriage 8.

On the other hand, when the case 1 is pulled in to the pull-in and push-out position C on the left side of I as shown by the imaginary line in FIG. When the case locking tool 25 is returned to the lowering limit position as shown in the figure, the lateral movement table driving means 16 moves the lateral movement table 15 to a position B near the right stroke limit as shown by the imaginary line in FIG. Move it to the left to a position FD near the stroke limit on the left side of the symmetry. As a result, the above-mentioned pull-in and push-out position C
The tip of the left case locking tool 25 is located directly below the left side locked piece 2b of the case 1 located at . At this time, the right case locking tool 26 is positioned below the case 1. Next, move the case handle + h tool 25 on the left side again to the 11th
As shown in the figure, the case locking tool driving means is rotated until its tip (roller 25 in FIG. 6) reaches an intermediate height where it does not engage with the locked piece 2b of the case 1 but can push the case 1. 31.

In this state, when the horizontal moving table 15 is moved toward the batting direction by the horizontal moving table driving means 16 to the stroke center position E as shown by the imaginary line in FIG. It is pushed back by the stopper 25 and moves to the pull-in and push-out position F on the right side, which is symmetrical to the position Hc near the stroke on the left side. Next, as shown in FIG. 12, the case locking tool 25, which was at the intermediate height, is returned to the lowering limit position, and the lateral movement table 15 is again moved to a position near the stroke limit on the left side of the surface by the lateral movement table driving means 16. When the case 1 is laterally moved back to the left until it reaches the position ilF, the tip of the right case locking tool 26 (roller 26a in FIG. In the state where it will be located, the case locking tool driving means 31 is rotated + h-axis 3
2 by a certain angle in the reverse direction, and as shown in Fig. 13, only the right case locking tool 26 is raised to an intermediate height that can push the case 1 located at the right pull-out position F. For example, move the lateral movement table 15 at a position near the left stroke limit to the left stroke limit position A shown in FIG.
The horizontal movement table driving means 16 moves the movement table to the right-hand stroke limit position G, which is symmetrical to the movement position G. As a result, case 1, which was at the right pull-out position 1F, is replaced by case locking tool 2 on the right side.
6, and is pushed out from the case holder 14 on the loading/unloading device 9 onto the loading/unloading case holder 12 as shown by the imaginary line in FIG.

When the case 1 has been pushed out onto the case holder 12 for loading/unloading, as shown in FIG. By horizontally returning the movable platform 15 to the standby position, for example to the stroke center position E, the series of unloading operations is completed.

The warehousing operation of storing the case 1 on the warehousing/unloading case holder 12 in the specific storage section 4 within the three-dimensional shelf 3 can be performed in the same manner as the above-mentioned warehousing operation. In this case, the case 1 on the case holder 12 for loading/unloading is transferred to the case holder 1 of the loading/unloading device 9.
4, the right case locking tool 26 and the left side locked piece 2b of the case 1 are used to pull the case 1 from above the case holder 14 of the loading/unloading device 9 to the case of the three-dimensional shelf 3. The case locking tool 25 on the left side is used to push the case into the storage section 4.

In the above embodiment, an example was explained in which case 1 pulled in from either the left or right side is pushed out to the opposite side, but when three-dimensional shelves 3 are installed on both sides of the crane passage, case 1 pulled in from one side on the left or right side is pushed out to the opposite side. Although it is conceivable that the product may be pushed out to the side in the opposite direction, the above-mentioned loading/unloading device 9 can of course also be used in this manner.

(Effect of the invention) As described above, the loading and unloading device of the present invention can move the horizontal Sendai,
By appropriately combining the separate lifting and lowering movements of the pair of case locking tools provided on this horizontal movement table, it is possible to push the case pulled in from either the left or right side toward the opposite direction, as shown in the example. This device can be effectively used as a loading/unloading device in an automatic safe using a case, but especially according to the configuration of the present invention, there is no need to use a conventional heddle conveyor or the like. Therefore, the structure is simple, and since the control of the heald conveyor and the like remains unchanged, the control can be easily performed, and the entire system can be implemented at low cost. Moreover, the total length of the loading/unloading device (the total length of the case holder 14) is
The length of the case to be handled plus the distance between both ends of the pair of case locking devices is sufficient, and the entire device can be configured more compactly than conventional devices that do not use a heat conveyor or the like. .
