Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mobile storage device that can improve storage efficiency by providing a row of mobile storages in front of a row of fixed storages. be.

[Prior Art] As a mobile storage device of this type, a plurality of mobile storages equipped with a drive mechanism are installed on the front side of a row of fixed storages in which a plurality of fixed storages are arranged side by side in the left and right direction. There is a known structure in which a plurality of rows of movable storages are arranged close to each other, and the front surface of a desired storage can be opened by moving the movable storages in the left-right direction.

By the way, in conventional systems, control for moving the mobile storage is generally performed in the following manner in response to operations performed on the operation panel. That is, in the conventional system, the current position of each movable storage is confirmed by a position sensor, and then reconfirmed by limit switches provided on the left and right sides of each movable storage, and the result is stored in the memory of the control device.

Then, the current position is compared with the desired movement position of the mobile storage specified by a signal manually inputted from the operation panel, and each Outputs a drive command signal to the mobile storage. As a result, the mobile storage moves to the position specified by the signal. Then, when the completion of the operation is confirmed by the position sensor and the left and right limit switches, the power supply to each mobile storage is stopped.

[Problem to be solved by the invention] However, such a device not only requires a large number of position sensors, but also requires that the control device be equipped with a memory for storing the current position of the mobile storage. is essential. and a current position stored in the memory;
Since calculations and pattern selection must be performed based on comparison with designated positions, it is necessary to use a control device with excellent calculation performance. Therefore,
There is a problem in that the configuration of the entire control system becomes complicated.

In the conventional system, the mobile storage units selected by calculation and pattern selection start operating at the same time, so the starting current peaks of each motor overlap, temporarily placing a large burden on the power supply. There is also the problem of applying Furthermore, since there are variations in the running speed of the mobile storage sheds that have started moving, there is also the problem that the following ones collide with the preceding storage storage rooms, preventing smooth movement.

Further, in such a device, if the mobile storage warehouse stops midway for some reason, the current position of the mobile storage storage cannot be confirmed, and the operation may become inoperable.

To prevent this, it is possible to use a position sensor that can continuously detect the position of each mobile storage, but using such a sensor would not only make the control device even more complicated, but also , If a stopped mobile storage is pushed by human power or the like and its stopping position changes, the drive mechanism will automatically start energizing, leading to the risk that the mobile storage will start moving unexpectedly. .

Also, in the conventional system, the storage to be moved is specified using the numeric keypad, so for example, if you want to specify the number 1 storage, do you press the 1 key?
There are some problems with operability, as it can be difficult to decide which keys to use.

Furthermore, with the conventional type, there is a risk that the mobile storage may start moving if another person operates the operation panel while entering the storage and taking out documents.

The present invention aims to solve such problems.

[Means for Solving the Problem] The present invention consists of a plurality of movable storages equipped with a drive mechanism on the front side of a fixed storage row in which a plurality of fixed storages are arranged side by side in the left and right direction. A plurality of rows of mobile storages are arranged close to each other, and the mobile storages are configured to be moved in the left and right direction to open the front side of a desired storage, and each of the mobile storages is located at the rightmost side or the leftmost side. A mobile storage device that defines a moved position as a reference pattern position, comprising an operating means for selecting a storage to be used, and a mobile storage when the selected storage is a mobile storage. a selection storage control means that outputs a drive command signal in the direction of the reference pattern position to the selected storage; and a drive command signal in the direction away from the reference pattern position to the mobile storage that will be located in front of the selected storage at the reference pattern position. a front storage storage control means that outputs a drive command signal to the right to a mobile storage that will be located on the right side of the selected storage at the reference pattern position; a left storage control means for outputting a leftward drive command signal to a mobile storage located to the left of the selected storage;
Each of the movable storages is provided with a drive stop means for stopping the drive of the corresponding movable storage when the movable storage comes into contact with or comes close to an object that impedes movement. .

In order to prevent the movable storage warehouse from suddenly starting to move when an external force is applied to the stopped mobile storage, a timer means disables the output of each of the drive command signals when a set time has elapsed after the operation. may be provided.

In addition, in order to be able to specify the storage you want to open without hesitation, the operating means is equipped with multiple operation switches, each corresponding to a storage that may be hidden by another storage. , when any of the operation switches is operated, the storage corresponding to the operation switch may be treated as the selected storage.

In this case, in order to clarify the correspondence between the actual storages and the operation switches, it is preferable to arrange the operation switches so as to approximate the arrangement of the storages.

In addition, in order to save the effort of manufacturing a separate operation panel each time according to the number of storage units arranged, the operation panel is provided with switch mounting holes that resemble the standard arrangement pattern of storage units. The operation switch may be attached only to the switch attachment hole corresponding to the actual storage, and the remaining switch attachment holes may be covered with blind members. The operation switch is
It may be a unit in which several pieces are connected together, or each piece may be independent.

Furthermore, in order to prevent the mobile storage from being activated unexpectedly during work such as putting in and taking out documents, etc., mats are attached to the floor corresponding to the row of mobile storage and output a signal when stepped on. It is preferable to provide a sensor and a stop command means for immediately stopping all moving storages regardless of the presence of the drive command signal when a signal is output from the mat sensor.

Note that when the stop command means is working, there is a risk that the operator may mistake it for a malfunction or power outage, so to prevent this, a sound may be generated when the signal is output from the mat sensor. It is also possible to provide an alarm means for issuing an alarm by means of light or the like.

[Function] With such a configuration, when the operating means selects the fixed storage to be used, the mobile storage that will be located in front of this fixed storage at the reference pattern position will have the following functions: A drive command signal is applied in a direction away from the reference position. In addition, in the mobile storage that will be located on the right side of the selected storage at the reference pattern position,
A drive command signal to the right is given, and a drive command signal to the left is given to the mobile storage located on the left side. In addition, if the mobile storages are closely lined up, only the first mobile storage with no obstacles in the direction of movement will start moving, and the time when the first mobile storage moves away from the next one. Then, the next mobile storage unit begins to move.

In this way, each of the mobile storages starts operating after some time, and finally there is no mobile storage in front of the selected fixed storage. While the mobile storage is moving, if a connected mobile storage is about to collide with the preceding mobile storage due to variations in travel speed, the driving stop means will temporarily stop the driving of the following mobile storage. will be stopped. Therefore, each mobile storage shed runs smoothly without causing a rear-end collision.

If the selected storage is a mobile storage, in addition to the above operations, a drive command signal in the direction of the reference pattern position is also given to the selected storage. Each mobile depot will be moved until no mobile depots exist.

Next, the operation of this embodiment will be explained.

First, it is assumed that the mobile storages 5 to 10 are stopped at predetermined reference pattern positions. That is, in this embodiment, as shown in FIG. 1, FIG. 3, and FIG. 6(a), the state in which the mobile storages 5 to 10 are positioned at the leftmost position is defined as the reference pattern position. . From this state, turn on the power and press the operation switches 281 to 287 corresponding to the storage warehouses 1 to 7 that you want to use.

1 to 107 are alternatively excited and self-maintained. In this case, for example, when the operation switch 28 corresponding to the first fixed storage 1 is depressed, the relay 101 for specifying the first selected storage is energized and self-held. As a result, the normally open contact 1 of the relay 101 interposed in the sequencer 25

Thereafter, when the starting switch 29 is pressed, the starting relay 110 is energized and self-held, and the normally open contact 110a of the relay 110 provided in the sequencer 25 is also closed. In this case, if the limit switches LSAR-LSPL are all released and turned OFF, the drive command relays A1, B1, C1, Dl, El, and Fl are energized, and the A drive command signal to the right should be output.

When the first mobile storage 7.10 travels for a certain amount of time and the limit switches LSBR and LSER of the following mobile storage 6.9 turn OFF, the drive command relays corresponding to these mobile storage 6.9 are turned off. 81 and El are also excited, and a rightward drive command signal is also output to these moving storages 6.9. Then, these mobile storages 6.9 move to the right by a certain amount, and the limit switches LSAR, LSAR, of the following mobile storages 5.8
When the LSDR is released, drive command relays A1 and Dl corresponding to these movable storages 5.8 are also excited, and these movable storages 5.8 also start moving to the right. Then, when the first mobile storage 7.10 moves to the right end,
The bumper 34R on the right side of the mobile storage comes into contact with one of the locking walls 21a protruding from both ends of the rail unit 21, and the right limit switches LSCR and LSPR are turned on. As a result, the excitation of the relays C1 and Fl for commanding the normally closed contact LXCRb 5LXFRb to open is stopped, and the power supply to the motors 21□ and 21□0 of the mobile storage 7.10 is cut off. These movable storages 7.10 are stopped at the right end by being stopped by a stopper (not shown). Next, when the subsequent mobile storage 6.9 approaches the stopped mobile storage 7.10 by a certain amount or more, the bumper 34R of the subsequent mobile storage 6.9 is moved to the previous mobile storage 7.10. 10 and elastically retracts inward, the right limit switch 34R of the movable storage 6.9 is turned ON.

As a result, the normally closed contacts LXBRb and LXERb are opened, and the excitation of the drive command relays B1 and El is stopped, and the motors 216, 21, . Power is cut off. In this way, one after another, the mobile storage 7.1
0.6.9.5.8 stops, and finally the front side of the fixed storage 1 that was selected is opened (see Figure 6). In addition, in the case where there is variation in the traveling speed of each of the mobile storages 5 to 10, and the following mobile storages 5, 6, 8.9 catch up with the preceding mobile storage 6.7.9.10, The subsequent mobile storage 5. 6.8. The right limit switch 34R of 9 is temporarily turned ON, and the moving storage 5, 6, 8.9 is decelerated. Therefore, each of the movable storages 5 to 10 smoothly moves at a distance of -window or more without colliding with each other.

From this state, for example, if it becomes necessary to use the mobile storage 6, press the operation switch 286 corresponding to the mobile storage 6, and then press the start switch 29. The selected moving storage 6 is driven in the reference pattern position direction, that is, in the left direction, as shown by the arrow in FIG. 6(b).
Mobile storage 5.8 located to the left of the mobile storage 6
also moves to the left. The mobile storage 9 that exists in front of the selected mobile storage 6 and the mobile storage 7 that exists to the left.
At 10, preparations are made to output a rightward drive command signal, but in the case of the illustrated example, those movable storages 7.9
．． 10 is the right limit switch LSCRSLSE
RSLS)'I? Since both are turned on, the motor is not driven to the right. However, in the end,
As shown in FIG. 6(C), the selected mobile storage 6
The entire area will be opened.

As described above, any of the operation switches 281 to 28
Even if 7 is operated, the front surfaces of storage cabinets 1 to 7 corresponding to the operation switches 281 to 287 will be opened.
If the emergency stop switch 31 is operated or the mat sensor 33 is stepped on while the mobile storages 5 to 10 are operating, the emergency stop relay 11 of the sequencer 25 is activated.
6 is energized and self-held. As a result, the stop command relay ST is energized, its normally closed contact STb is opened, and the energization of the starting relay 110 is stopped.

Therefore, all the drive command relays A1 to F2 become de-energized, and all the movable storages 5 to 10 stop on the spot. In that case, the melody voice generator 36 is energized to make an alarm sound (a predetermined melody) indicating that an emergency stop is being made.
is emitted. If an obstacle exists in a location that cannot be detected by the mat sensor 33, the bumpers 34R and 34L of the mobile storage units 5 to 10 come into contact with the obstacle and the limit switches LSAR-LSPL are switched. Then, the driving of these mobile storages 5 to 10 is stopped.

By the way, in this case, the contact T1a of the timer T1 is activated when the set time, that is, 10 seconds in this embodiment, has elapsed since the start switch 29 was pressed and the mobile storage units 5 to 10 were actually activated. is closed, and relay ST for stop command is energized.

Therefore, the excitation of the starting relay 110 is stopped, the drive command relays A1 to F2 are de-energized, and the drive command signal is deenergized. Therefore, even if the limit switch LSAR-LSI'L is opened, until the next operation is performed, the motor 2 of each mobile storage 5 to 10
15 to 21, o will not be energized. Therefore, even if the stop positions of the movable storages 5 to 10 are changed by external force, it is impossible for the movable storages 5 to 10 to suddenly be energized again and start moving.

It goes without saying that the consecutive losses of fixed storages and mobile storages, or the number of rows of mobile storages, are not limited to those in the embodiments described above.

Further, the fixed storage does not need to be separable into units, and may be continuous.

[Effects of the Invention] Since the present invention has the above configuration, the following effects can be obtained.

First, in the present invention, when any storage is selected, the selected storage control means, the front storage control means, and the left and right storage control means are controlled regardless of the current position of the mobile storage. The means outputs a drive command signal in the left or right direction, and stopping of the movable storage is performed only by a separate drive stop means, so that, for example, the current position of each movable storage is There is no need to perform control such as detecting the position and comparing the position with a position specified by an external operation to determine in advance the position of each mobile storage after the movement. Therefore, a position sensor for detecting the current position of each mobile storage is not required, and the procedure of storing and arithmetic processing the feedback signal from the position sensor to determine the position after movement can be omitted. Therefore, appropriate control can be performed using a simple control circuit such as a sequencer that does not have any memory or the like for storing the current position.

Moreover, according to the present invention, since the mobile storage units start moving sequentially after a certain period of time, starting from the first one, it is possible to prevent the starting current peaks from overlapping when starting the motors of the respective mobile storage units. can do. Therefore, the mobile storage can be easily moved using a power supply device with a relatively small capacity.

With such a system, even if the mobile storage is stopped midway, each mobile storage can be moved in the desired direction without any problems by performing the selection operation. The front of the specified vault will be opened.

Additionally, if a timer is installed to limit the output time of the drive command signal, safety will be improved by eliminating the problem of power being suddenly restarted when a stopped mobile storage is moved by external force. be able to.

Furthermore, by configuring the operating means with multiple operating switches and having each operating switch correspond to the storage you want to use, you can enjoy the convenience of being able to operate directly without any hesitation. .

In particular, if the operation switches are arranged to approximate the layout of the storage, you can easily select the storage you need even if the number attached to the storage is hidden and cannot be read. Become.

In addition, if the operation panel is provided with switch mounting holes that resemble the standard arrangement pattern of storage cabinets, and the operation buttons are installed using only the necessary switch mounting holes, the operation will be easier. Boards can be standardized and manufactured in advance.

On the other hand, if a mat sensor is installed, it is possible to prohibit the movement of the mobile storage in the event that a person enters the moving space of the storage or if some obstacle has fallen on the floor. This can improve safety.

Also, if a signal is output from the mat sensor, an alarm can be issued with a sound or light.
It is possible to eliminate the problem of the person performing the operation mistaking it for a malfunction or power outage.
