Abstract

PURPOSE:To simplify the structure of casing locks provided in a storage installation, by providing such an arrangement that the locks for preventing casings on a shelf from slipping out due to, for example, earthquakes, are shifted into its released condition by means of a cam when an actuator for changing over the locks into its released condition is pressed by a pusher. CONSTITUTION:A pusher 39 arranged slidably in a horizontal direction in a drive section at the lower end of a travel crane which is movable along the front surface of a shelf 1 having several casing support sections 3 arranged vertically and laterally, is moved forward in association with operation of a motor and is therefore made abut against the projecting end 26a of a rod 26 in an actuator 23 so that the rod 26 is moved leftward overcoming a spring 29. Then, a plate-like cam 30 which moves together with the rod 26 pulls down an elevating rod 15, overcoming a spring 20, through the inclined cam surface 30a of the cam 30, a follower roller 21 and an arched frame member 22. Therefore, all casing locks 17 attached to the elevating rod 15 is released downward from handles 6b provided to casings 7 which are therefore released from their locked condition.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a storage facility comprising a shelf for supporting cases and a running lane for loading and unloading cases between the shelves. This invention relates to a storage facility equipped with a case locking device to prevent the case from sliding from the shelf toward the crane travel path due to an earthquake or the like.

In conventional storage equipment of this type, a driving means for switching the case locking device to the unlocked state is provided within the shelf. Therefore, for example, even if a plurality of case locking devices belonging to all the case support sections in the same row in the vertical direction are configured to be switched to the unlocked state by a single drive means, there will be a large number of case locking devices for the entire shelf. This requires a driving means, which greatly increases the equipment cost. In order to solve these problems, the drive means is provided not on the shelf but on the crane side, and on the shelf side, an operating tool for switching each case locking device to a unlocked state is provided. A configuration has been considered in which the unlocking operation tool at the position where the crane is stopped is operated by a drive means on the crane side, and the target case locking tool is switched to the unlocking state.

The present invention aims to more practically improve a storage facility in which a drive means for switching the case locking device to the unlocked state is provided on the crane side, and one implementation thereof is as follows. An example will be explained based on the attached illustrative figures.

It is biased toward the crane travel path 2 by a coil spring 29 interposed between the spring receiving seat 28 and the spring receiving seat 28 . The tip of the plate-shaped cam 3o attached to the rear end of the rod 26 (on the back side of the shelf 1) is arranged so that the cam slope 5oa formed on the lower side near the tip corresponds to the cam driven roller 21. It is loosely fitted into the portal member 22.

As shown in FIGS. 3 and 4, a casing 24 is provided near the front end (crane travel path 2 side) of the operating tool 23.
A locking means 51 is also provided inside. As shown in FIG. 5, this locking means 51 is composed of a movable plate 54 supported on a placket 55 so as to be vertically swingable by a support shaft 52, and a torsion spring 55 that biases the movable plate 34 downward. The movable plate 2s4 includes a hook portion 54a that fits into a locked recess 56 formed on the upper side near the front end of the rod 26 to prevent the rod 26 from moving backward, and a hook portion 54a that prevents the rod 26 from moving forward. A stopper portion 54b is formed to stop the movement. This stopper portion 54b fits into a recess 57 formed in a vertical stepped surface between the rod 26 and the protruding shaft portion 26a. In addition, at the front end of the casing 24, there is a glue 1; 1 part (support 4) of the shelf 1 on the crane travel path 2 side
A cover play) 24a flush with the front surface of a) is provided,
An operating opening 58 is formed in the cover plate 24a, into which the front end of the protruding shaft portion 26a of the operating tool 23 is loosely fitted in the road surface.

As shown in FIGS. 1 and 2, the driving lane 8
At the lower end thereof, there is provided a pusher 39 for suppressing and moving the corresponding one-channel cutting tool 23, and a drive means 40 for this pusher 39.
is provided. As shown in FIGS. 6 to 8, the driving means 40 includes a pair of slide guides 41a and 41b.
A slide rod 42 that is slidably supported in a horizontal direction perpendicular to the crane traveling direction and whose one end constitutes the pusher 39;
a pair of coil springs 43a that hold the
43b, a pinion gear 45 that meshes with a rank gear portion 44 formed on the slide rod 42', and a motor 46 that drives this pinion gear 45.
There is. The pair of springs 43a and 4i6b are loosely fitted into the slide rod 42 and one guide rod 47 installed in the Jp row, and each outer end thereof is connected to the guide rod 47.
The inner end is fixed to a movable member 49 that is fixedly connected to the slide rod 42 and is fitted to the guide rod 47 so as to be relatively movable. The movable spring receiving seats 51a and 51b are loosely fitted to the guide rod 47 so as to sandwich the stopper 50 from both sides. Further, a switch operating member 52 is attached to the slide rod 42, and a limit switch 5 is operated by the switch operating member 52 when the slidable l'42 is in the neutral position.
6, and a limit switch 54 that is operated by the switch operating member 52 when the slide rod 42 moves forward a predetermined distance.

The tip of the slide rod 42, that is, the pressing end of the pusher 59, is brought close to the shelf 1 within a range that does not interfere with the running of the lane 8, and stops the lane 8 running at a predetermined position for loading and unloading operations. At this time, the operating end of the operating tool 2'5, which is interlocked with the case support part 6 to be subjected to the loading/unloading operation via the attached case locking tool 17 and the lifting rod 15, is opposed to the tip protruding shaft portion 26a of the rod 26. do. As shown in FIG.
A protruding piece 59a is provided to press and move the protruding piece 59a upward.

Next, to explain how to use it and its function, it runs on the lane 8 that is used for loading and unloading work, and also lifts and lowers the carriage 11.
When the elevating carriage 11 is positioned at a predetermined position corresponding to the case support part 6 to be loaded and unloaded, the motor 46 in the drive means 40 at the lower end of the lane is operated, and the pinion gear 45 is rotated once to move the slide rod 42 forward. This forward movement of the slide rod 42 is caused by the movement of the movable member 49 into the movable spring receiving seat 51.
One spring 43a is compressed through the movable spring receiving seat 51b of the other spring 45b.
Since the spring 43-b is in contact with the fixed stopper 50, the spring 43-b does not expand.

As a result of the slide rod 42 moving forward as described above,
The integrated pusher 39 moves forward toward the shelf 1 side, and the operating end of the pusher 39 moves toward the operating tool 26 as shown by the imaginary line in FIG.
The operating tool 23, ie, the rod 26, is pressed and moved rearward against the spring 29. Immediately after the backward movement of this rod 26 is started,
That is, when the rod 26 moves backward to the position where the recess 67 and the stopper part 154b of the movable plate 54 are separated, the operating end protruding piece +69a of the pusher 259 engages the locking means 3.
Since the first movable plate 34 is pressed and rotated upward around the support shaft 32 against the spring 65, the hook portion t54a of the movable plate 54 is disengaged from the locked recess 36 of the rod 26.

In this way, the backward movement of the rod 26 continues, but as shown by the imaginary line in FIG. 22, the lifting rod 15 is pulled down against the spring 20. When the lifting rod 15 is completely lowered, the forward movement of the pusher 59 on the crane δ side is stopped. This stopping operation is performed by sending a message to the limit switch 5 through the switch operating member 52 that the slide rod 42 has moved forward by a certain distance.
By detecting in step 4, it can be performed automatically. Of course, it is necessary to hold the stopped slide rod 42 so that it does not move backward due to the pressing force of the spring 43a, for example by using a motor with a brake as the motor 46.

By lowering the elevating rod 15 by a certain amount as described above, all the case locking devices 17 attached to the elevating rod 15, that is, the case supports 6 that are subject to loading and unloading operations are placed in one column. All case supports 6 that belong to
The case locking tools 17 disposed in each of the cases 7 are lowered, and the case 7 stored in the case support 6 is detached downward from the handle 6b, and is placed in the empty case support 6. In this case, the case 7 is lowered to a height that does not interfere with storage of the case 7.

In this state, the case 7 is loaded and unloaded by the case loading/unloading device 12 between the case support section 6 to be loaded/unloaded and the top of the elevating/lowering carriage 11. The driving means 40
This can be done automatically in conjunction with the limit switch 54 detecting that the slide rod 42 has moved forward by a predetermined distance in the process.

When the loading/unloading operation of the case 7 to/from the case support section 6 to be loaded/unloaded is completed, the driving means 4 on the crane side
0, the brake of the motor 46 is released and the pinion gear 45 is switched to a state where it can freely rotate, and the slide rod 42 is moved backward to the neutral position by the pressing force of the spring 46a, or the pinion gear 45 is driven in reverse by the motor 46. The slide rod 42 is forcibly moved backward. In this way, the pusher 59 is returned to its original standby position, but in any case, the brake is not applied to the motor 46 and the slide rod 4
2 is in a free state, the slide rod 42 and pusher 259 are held in a neutral position in a self-centering manner by a pair of springs 43a and 43b.

When the pusher 39 returns to the backward position, the operating tool 25 on the shelf 1 side,
That is, the rod 26 is moved to the third position by the pressing force of the spring 29.
It automatically returns to the standby position shown by the solid line in the figure, and the pulling down action of the elevating rod 15 by the plate-shaped cam 2!10 is released, and the elevating rod 15 is automatically raised to its original height by the pressing force of the spring 20. Therefore, each case locking tool 17 attached to the lifting rod 15 rises, and the handle 6 of the case 7 stored in the case support part 6 is lifted.
b, and becomes in a state where the case 7 is prevented from moving toward the crane travel path 2 side.

Note that the return of the pusher 69 to its normal position can be detected by the limit switch 525. Furthermore, while the pusher 259 is pushing the rod 26, the movable plate 34 of the locking means 61 is pushed up onto the pusher 39;
6, the movable plate 54 automatically rotates downward due to the biasing force of the spring 35, and the hook portion 34 at the tip of the movable plate 54 automatically rotates downward.
a fits into the locked recess 56 of the rod 26 to lock the rod 26 again. At the same time, the movable plate 34
The stopper part 154b fits into the recess 57 of the rod 26, and the rod 26 is moved back by the pressing force of the spring 29.
to stop at a predetermined position.

In the embodiment shown in FIG. 9, the rod 26 constituting the operating tool 25 has a reflecting plate 56 suspended by a horizontal support shaft 55 in a direction perpendicular to the moving direction of the rod 26. A regulating plate 57 is provided to rotate the reflecting plate 56 upward when the reflecting plate 56 returns to a predetermined position,
Further, on the crane side, there is a reflective photoelectric switch 5 for detecting a state in which the reflector plate 56 has come off the regulating plate 57 and is hanging down.
There are 8. According to this embodiment, when the rod 26 moves forward against the spring 29, that is, when the lifting rod 15 is pulled down and the case locking tool 17 is released downward from the case handle 6b, the reflection plate 56 is As shown by the line, the reflector plate 56 is detached from the regulating plate 57 and hangs down, and the hanging reflector plate 56 can be detected on the crane 8 side by the reflective photoelectric switch 58. case loading/unloading device 1
2 can be activated automatically. In this case, the glue mint switch 54 on the crane side can be omitted. In addition, a reflector plate is attached to the lower end of the portal member 22 connected to the crushing rod 15, and the fact that the elevating rod 15 has been lowered to a predetermined position is directly detected by a reflective photoelectric switch 58 on the crane side via the reflector plate. It is also possible to configure it so that it can be detected.

The storage equipment with a case locking device of the present invention can be implemented as described above.According to the storage equipment of the present invention, even if the shelf shakes slightly due to an earthquake, etc., the stored cases will not be accidentally damaged. Since the locking device can reliably prevent the case from slipping out of the case supporting section, it can prevent dangerous situations such as the stored case protruding into the crane travel path or falling into the crane travel path. This can be prevented. In addition, this locking device can be automatically switched to the unlocking position during loading/unloading operations by a locking release pusher provided on the crane side, so a large number of locking release driving means are provided on the shelf side. This is not necessary, and the intended purpose can be achieved economically by simply providing one lock release pusher on the crane side for a large number of locking devices belonging to one shelf.

Moreover, according to the configuration of the present invention, the operating tool for switching each locking tool to the unlocked state is disposed at the lower end of the shelf in such a manner that the operating end thereof does not protrude from the shelf toward the crane travel path. A pusher for suppressing the corresponding unlocking operation tool is disposed at the lower end of the lane in which the lane is run, with the pushing end of the pusher being close to the operation end of the operation tool. Therefore, even if the shelf or crane becomes deformed over time,
The relative positional relationship between the operating tool on the shelf side and the pusher on the crane side can be maintained as expected, and reliable operation can be performed at all times. Furthermore, since the operator does not protrude from the shelf side into the crane travel path, workers who perform maintenance and inspection can safely pass through the crane travel path. Moreover, since the operating end of the operating tool on the shelf side and the pressing end of the pusher on the crane side are close to each other, the loss time between pusher operation and operating tool operation is minimized, reducing the cycle time of loading and unloading work. It is possible.

In addition, since the pusher for operating the operating tool on the shelf side in the unlocking direction was provided on the running lane side, the movement of the pusher was detected or a misoto switch etc. was used as shown in the example. It is also possible to indirectly detect the state of the case locking device on the shelf side on the crane side. Therefore, compared to the case where this type of detection means is installed on the shelf side, the signal transmission system such as wiring for introducing the detection results to the control panel installed in the lane in which the vehicle runs is extremely simple. ,
In particular, as shown in the embodiment of FIG. 9, the movement of the operating tool on the shelf side and the movable member (lifting rod 15 in the embodiment) that interlocks this operating tool and the case locking tool can be detected from the crane side. With this configuration, the state of the case locking tool can be detected more accurately on the crane side.

Further, in the embodiment, the shelves 1 are erected only on one side of the crane travel path 2, but the shelves 1 can also be erected on both left and right sides of the passage 2 in parallel with each other. In this case, on the crane 8 side,
It is necessary to provide a pusher for operating the operating tool 23 on one shelf, a pusher for operating the operating tool 26 on the other shelf, and a driving means for selectively driving both of these pushers, but the drive of the above embodiment is required. The slide rod 42 in the means 40 is configured to be movable to either the left or right side with respect to the neutral position, and both ends of this single slide rod 42 are extended to the left and right shelves to serve as pushers, respectively. This simplifies the structure.
