Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable shelving device having a plurality of shelving devices movable on rails, and in which the width of a passage selectively formed between each shelving device is set to a predetermined width. This allows it to be made to any width narrower than the specified width.

A mobile shelving device is already known in which a plurality of shelving devices are provided in parallel on a rail and passages can be selectively formed between each shelving device, so that space can be used efficiently. . In such a device, if each shelf device is driven by a motor,
The moved shelving apparatus is configured to stop when a path of a certain width is formed between the selected shelving apparatuses. The width of the passage is sufficient for storing articles on the shelving devices located on both sides thereof and for taking out the articles stored therein. For safety reasons, a worker enters the passageway formed between the shelving devices to store or take out articles only after all of the moving shelving devices have stopped.

Therefore, even if the purpose of entering the formed passageway is a passageway narrower than the prescribed width, it is necessary to wait until all the shelving devices moving at low speed have stopped; When we are busy, we waste a lot of time.

The present invention solves the above problem by allowing the user of the device to arbitrarily stop all of the shelving devices driven by a motor before they form a path of a predetermined width. It is.

The gist of the present invention is that a plurality of shelving devices are arranged movably in a direction perpendicular to their storage surfaces, and that by moving the shelving devices, a path of a predetermined width can be created between them. In the electric movable shelving device to be formed, each shelving device is provided with an aisle switch and a reset switch, and the first signal output by operating the aisle switch of a specific shelving device for which an aisle is to be formed is used to control the shelving device. A movement command signal is output, and while the shelving device is moving, the movement command signal is stopped by a second signal output by operating the passage switch again before the formation of a passage of a predetermined width is completed. and a normal stop signal is output, and the stop signal output based on the normal stop signal continues to be output regardless of the operation of any aisle switch or reset switch of other shelving devices, and all shelf devices are stopped. Only when the state is maintained and the path switch of the specific shelf device is operated again and again, a movement command signal similar to the first signal is output, the shelf device starts again, and the reset switch of the specific shelf device is activated. This is a normal stop device for an electric movable shelf device in which all the circuits are reset only when the device is operated, allowing selection of insects in other aisles.

This is shown as an example in the drawings, and an explanation will be given of a device consisting of one fixed shelf device and three movable shelf devices: 1A, 1B, 1
C and 1D are shelf devices arranged parallel to each other in the depth direction, and among these, the leftmost shelf device 1A
is fixed and installed near a wall surface of a warehouse or the like, and other shelf devices 1B, 1C, and 1D are movable along rails 2 arranged in a direction orthogonal to the storage surface thereof. Therefore, each of the shelf devices 1B, 1C, and 1D includes an appropriate number of wheels 3 that are engaged with the rail 2, and reversible motors 4B, 4C, and 4D that drive the wheels 3.

A, B, C, and D indicate passages formed between each shelf device 1, and in FIG. 3, passage B is formed.

The shelf devices 1B, 1C, and 1D have left limit switches 5B and 5B provided at their bottoms facing the floor.
5C, 5D, right limit switch 6B, 6C,
6D, and when the shelf devices 1B, 1C, and 1D are brought close to the shelf device 1A and focused on the shelf device 1A side, the left limit switches 5B, 5C, and 5D face only each of them, and only those Actuators 7B, 7C, 7D that come into contact with the shelf device 1A
Shelving device 1
Actuators 8B, 8C, and 8D are arranged on the floor so that when B, 1C, and 1D are focused to the right side, they face only the right limit switches 6B, 6C, and 6D, and only come into contact with them. Therefore, each of the limit switches 5 and 6 can be adjusted by shifting the position in the width direction of each of the shelf devices 1B, 1C, and 1D.
Different limit switches are prevented from coming into contact with different actuators.

These limit switches 5 and 6 are the shelf devices 1B,
1C and 1D respectively regulate the moving distance when moving to the right or left.
Each of D is actuator 7B, 7C, 7D
The shelf device is restricted from moving any further to the left while in contact with the shelf device.

The actuators 7 and 8 can be arranged in any manner, but as illustrated in FIG.
If you fit it inside, you can easily set its position.
It is also possible to reduce obstructions when passing through the passage formed between the shelf devices. The actuators 7 and 8 may be fixed, or their positions may be adjustable in a direction parallel to the movement direction of the shelf device.

Each shelf device 1 has a control circuit, one of which is a main control circuit 10, and in this embodiment, it is provided in the leftmost shelf device 1A, and the other shelf devices 1B, 1

In this embodiment, each switch 13, 14 is provided at the end of each shelf device on the aisle side, but there is no need to limit the position thereof. FIG. 8 is a block diagram of the main control circuit 10. Signals from the path switch 13A and others are applied to the path control circuit 15A. The path control circuit 15A has output terminals 16A, 17A, 18A, and 19A, and when the first signal is input from the path switch 13A when no other path has been selected, the output terminal 16A selects the other path. A movement command signal is output to instruct the shelf device to move, and at the same time, the output terminal 17A outputs an aisle selection signal. Passage switch 13A again
When is pressed and it outputs a second signal, the movement command signal at output terminal 16A stops and output terminal 18A outputs a normal stop signal. The outputs of the output terminals 16A and 18A are switched by, for example, inverting a flip-flop.

When the passage switch 13A is pressed while the other passage selection signal indicating that another passage has already been selected is applied to the passage control circuit 15A, the output terminal 19A outputs an abnormal stop signal. (Hereinafter, the code of each output terminal is attached to the name of the signal output from each output terminal to indicate the signal output from that output terminal. For example, the movement command signal 16A is a signal output from the output terminal 16A. (The same applies to subsequent circuits.) The reset circuit 20A is the reset switch 14A.
Output terminal 2 outputs a reset signal using the signal from
1A and when the other path selection signal is input to the reset circuit 20A, the reset switch 14A
Output terminal 22 that outputs an abnormal stop signal when is pressed
It has A.

When the stop control circuit 23A receives the normal stop signal 18A or the abnormal stop signals 19A and 22A, it outputs a stop signal from its output terminal 24A and a stop signal from its output terminal 25A.

26A is a lamp control circuit, which turns on the RUN lamp 2 when the path selection signal 17A is input.
7A is turned on, and when the normal stop signal 18A is applied, the reset lamp 28A is turned on. Also,
If the path switch 13A or the reset switch 14A is pressed while the other path selection signal is applied to the path control circuit 15A and the reset circuit 20A, the normal stop signal 18 of the path control circuit 15A is activated.
A is not output, and the stop signal 25A output by the stop control circuit 23A is applied to the lamp control circuit 26A. Lamp control circuit 26A to which stop signal 25A is applied without normal stop signal 18A being applied
The output causes the reset lamp 28A to start blinking.

Reference numeral 29 denotes a path formation completion determination circuit, which is a circuit that determines that the movement of the shelf device 1 that has been moved corresponding to the selected path has been completed. This circuit 29 is connected to its output terminal 3 when the motor ON signal indicating that all or any of the motors 4 is being driven is inputted from an adjacent shelf device.
A path formation completion signal is output from 0 and applied to the path control circuit 15A.

FIG. 9 is a block diagram of the sub-control circuit 11B of the shelf device 1B, and the other sub-control circuits 11C, 1
Since the same applies to 1D, illustration thereof is omitted. Note that the sub control circuit 1 in the sub control circuits 11C and 11D
Circuits that are the same as each circuit in 1B are indicated by C or D in the same numerical column. This also applies between the main control circuit 10 and each sub-control circuit 11. Then, passage control circuit 15B, reset circuit 20B, stop control circuit 23B, lamp control circuit 2
6B has the same output terminals as the corresponding circuits of the main control circuit 10 and operates almost the same way, so it will be explained below.

The direction selection circuit 31B of the sub-control circuit 11B is a circuit that instructs the moving direction of the shelf device, and this circuit
The direction selection circuits 31 of the left and right shelf devices are connected to each other. However, in this embodiment, since the shelf device 1A does not move, a direction selection circuit is not required, so as is clear from FIG. 8, the shelf device 1A is connected to its path control circuit 15A. There is.

When the aisle switch 13B of the shelf device 1B is pressed,
When the movement command signal 16B is input to the direction selection circuit 31B, the direction selection circuit 31B sends a left command signal to the left shelf device 1A from its output terminal 32B, and a right command signal to the right shelf device 1C from its output terminal 33B. Each command signal is applied to the start delay circuit 34B.
Then, a left signal is inputted from the output terminal 35B to instruct the shelf device 1B that its moving direction is to the left. Furthermore, when the aisle switch 13 of a shelf device other than the shelf device 1B is operated, for example, when the aisle switch 13A of the shelf device 1A is operated, a right command signal is input to the direction selection circuit 31B. Upon receiving the right command signal, the direction selection circuit 31B outputs a right signal from its output terminal 36B, inputs it to the delay circuit 34B, and outputs the right signal from its output terminal 37B.
Then, the other aisle selection signal is applied to the aisle control circuit 15B and the reset circuit 20B, and furthermore, the right command signal 33B is applied to the shelf device 1C. Shelving device 1C, 1D
When the passage switch 13 is operated, the direction selection circuit 31B receives the left command signal and outputs the left command signal 32B, the left signal 35B, and the other passage selection signal 37B.

The start delay circuit 34B is a circuit that has a timer and creates a time difference in the start of each shelf device when a plurality of shelf devices 1 move. is connected to the input terminal of the start delay circuit 34, and outputs a start signal from the output terminal 38B to notify the left and right shelf devices when the shelf device 1B starts. However, in this embodiment, since the shelf device 1A does not move, the passage formation completion determination circuit 29 is connected to the shelf device 1A.

Then, when the left signal 35B is applied to the start delay circuit 34B and the start signal 38A is applied from the shelf device 1A, or when the right signal 3
When the start signal 38C is applied from the shelf device 6B and the shelf device 1C, the timer thereof is activated;
After a certain period of time, in response to the left signal 35B or right signal 36B input from the direction selection circuit 31B,
Left signal from output terminal 39B or output terminal 40B
, one of the right signals is applied to the motor control circuit 41B. Note that even if the left or right command signal 32, 33 is input to the shelf device 1B, if there is no movement space in that command direction, that is, if the signal is output from the limit switch 5B or 6B in that direction, The start delay circuit 34B outputs a start signal regardless of the start signal 38 input from the adjacent shelf device. This also applies to the shelf devices 1C and 1D.

The motor control circuit 41B receives the input left signal 3.
9 or the right signal 40, a left drive signal is output from the output terminal 42B and a right drive signal is output from the output terminal 43B to the motor 4B. However, when signals are output from limit switches 5B and 6B, drive signals 42B and 43B in that direction
is not output. When the drive signals 42B and 43B are output, the motor control circuit 41B sends the motor ON signal from its output terminal 44B to its output terminal 45B.
The motor ON signal 44B is sent to the start delay circuit 34 of all the sub-control circuits 11 and the path formation completion determination circuit 2 of the shelf device 1A.
9 is input. When motor signal 45B is applied to lamp control circuit 26B, lamp control circuit 26
B causes the run lamp 27B to blink. This operation is the same for the motor control circuits 41 of all shelf devices. When a stop signal 24 is output from any one of the stop control circuits 23 of the main control circuit 10 and all the sub control circuits 11, the stop signal 24 is transmitted to the motor control circuits of all the sub control circuits 11. 41 and the motor 4 being driven
stop everything.

The start delay circuit 34B has its path switch 15
With B pressed, a start signal 38 is input from the left and right shelf devices 1, and a signal is input from either the left or right limit switches 5B, 6B. In other words, you can confirm that it is stopped, and
When the motor ON signal 44B disappears, a path formation completion signal is applied from its output terminal 46B to the aging control circuit 15B. In addition, passage switch 13
The shelf device in which is not pressed also outputs the path formation completion signal 46 when the same conditions as above are met, but the completion signal in this case has no effect on other circuits. When the start signal 38 disappears, the timer of the delay circuit 34B is reset.

Lead wires 47 and 4 for left and right limit switches 5 and 6
8 is connected to the start delay circuit 34 and motor control circuit 41 of each sub-control circuit 11. 4
9 is a motor drive circuit.

In this embodiment, since the shelf device 1A is located at the left end, the movement command signal 16 outputted from the aisle control circuit 15A is directly inputted as the right command signal 33 to the direction selection circuit 31B of the shelf device 1B. Ru. Then, the left command signal 32 output from the shelving device 1B is directly input to the aisle control circuit 15A as an other aisle selection signal, and is used as a start signal for the shelving device 1A to the start delay circuit 34B of the shelving device 1B. is input. If the shelf 1A is also made movable, a start delay circuit, a motor control circuit, a motor control circuit,
Just add a motor.

In this embodiment, the run lamp 27 is incorporated in the passage switch 13, and the reset lamp 28 is incorporated in the reset switch 14, so the illustration of the lamps 27 and 28 is omitted in FIG.
7 and 28 can also be provided independently. The first signal and the second signal input to the passage control circuit 15 are shared by one passage switch 13, but a dedicated switch is used for inputting the first signal and the second signal. It is also possible to provide

The path in this device is formed from a state in which all of the shelf devices 1 are advanced to the left as shown in FIGS. 1 and 2, to a path B between the shelf devices 1B and 1C as shown in FIG. Let's explain when to do this.

When aisle B is selected, the aisle switch 13B of the shelf device 1B is pressed and the first signal is input to the aisle control circuit 15B. The passage control circuit 15B to which the first signal has been input inputs the movement command signal 16B to the direction selection circuit 31B and the passage selection signal 17B to the lamp control circuit 26B. As a result, the run lamp 27B lights up to indicate that passage B has been selected, and the direction selection circuit 31B sends the left command signal 32B to the left shelf device 1A, and the right command signal 33B to the left shelf device 1A.
is input to the shelf device 1C. Since the shelf device 1A is a fixed shelf, the left command signal 32B is directly applied to the start delay circuit 34B of the shelf device 1B as the left start signal 38 of the shelf device 1A, and in the shelf device 1A,
The left command signal 32B is also input as the other path selection signal 37 to the path control circuit 15A and the reset circuit 20A. On the other hand, since the direction selection circuit 31B applies the left signal 35B to the start delay circuit 34B, when the left start signal 38 is input to the delay circuit 34B from the shelf device 1A, the timer is activated in the start delay circuit 34B. After a certain period of time, preparations for starting the shelf device 1B to the left are completed. However, since the left limit switch 5B is activated and its limit signal is input to the delay circuit 34B and the motor control circuit 41B, the left drive signal 42B is not output from the motor control circuit 41B, and the shelf apparatus 1B does not move.
Note that by inputting the left signal 35 from the direction selection circuit 31B to the delay circuit 34B, the start signal 38 thereof is sent from the shelf device 1B to the shelf devices 1A and 1C, but the shelf device 1A is a fixed shelf. , shelf device 1
Since C selects the right direction and receives a signal from the right shelf device 1D, the start signal 38
B does not affect the operation of the circuits of the shelf devices 1A and 1C.

The direction selection circuit 31C of the shelf device 1C, which has received the right command signal 33B from the direction selection circuit 31B of the shelf device 1B, applies the right command signal 33C to the direction selection circuit 31D of the shelf device 1D. As a result, the direction selection circuits 31C and 31D are connected to the respective delay circuits 34
Right signals 36C and 36D are applied to C and 34D, and passage control circuits 15C and 15D and reset circuit 2
Other path selection signals 37C, 37D for 0C, 20D
Apply. The direction selection circuit 31D of the shelf device 1D outputs the right command signal 33D, but since the shelf device 1D is located at the right end, the right command signal 33D is directly output to the right start signal 33D as shown in FIG.
The signal is then input to the delay circuit 34D of the shelf device 1D.

As described above, the selection circuit 31D is connected to the delay circuit 34D of the shelf device 1D to which the right start signal 38 is applied.
Since the right signal 36D is already applied from
These signals activate the timer, and after a certain period of time, the delay circuit 34D applies the right signal 40D to the motor control circuit 41D. As a result, the motor control circuit 41D confirms that the right limit switch 6D is not outputting, applies the right drive signal 43D to the motor 4D, and drives the motor 4D in a direction to move the shelf device 1D to the right. do. Driven by the motor 4D, the shelf device 1D moves to the right. While the motor 4D is driving, the motor control circuit 41D
The lamp control circuit 26D outputs the ON signal 44D to notify other shelving devices that the shelving device 1D is moving, and the lamp control circuit 26D to which the motor signal 44D is input blinks the lamp 27D using that signal to Device 1
Display that D is moving.

When the shelf device 1D starts as described above, the signal is input as the start signal 38 to the delay circuit 34C of the shelf device 1C. In the delay circuit 34C to which the start signal 38 is applied, its timer operates, and after a certain period of time, the right signal 40C is sent to the motor control circuit 41C.
By applying this, the shelf device 1C also moves to the right with a slight time delay, similar to the shelf device 1D.

As described above, the shelf device 1D starts first, and the shelf device 1C starts a little later. When the right limit switch 6D of the shelf device 1D contacts the actuator 8D and its signal is input to the delay circuit 34D and the motor control circuit 41D, the motor ON signal 44D is stopped and the shelf device 1D is stopped. The shelf device 1C also stops when the right limit switch 6C contacts the actuator 8C. When the shelf devices 1D and 1C are stopped one after another, the motor ON signal 44 of each one disappears, so the run lamps 27D and 27C are also turned off one after another, and a passage B is formed as shown in FIG. 3.

When the shelf device 1C starts, its delay circuit 34C
From there, a start signal 38 is sent to the delay circuit 34B of the shelf device 1B.
is input, but at this time motor ON signal 4
4C is input, the delay circuit 34B does not output the path formation completion signal 46B. When the shelf device 1C stops and its motor ON signal 44C disappears, the start signal 38 from the shelf devices 1A and 1C and the stop of the shelf device 1B are confirmed, and the passage formation completion signal 46B is sent from the delay circuit 34B to control the passage. applied to circuit 15B.

Upon receiving the passage formation completion signal 46B, the passage control circuit 15B stops outputting the movement command signal 16B and applies the normal stop signal 18B to the stop control circuit 23B. A stop signal 24 is input. Furthermore,
The stop signal 24B and the normal stop signal 18B are input to the lamp control circuit 26B, and the lamp control circuit 26B turns on the reset lamp 28B. In this state, the stop signal 24B continues to be output.
Since all the shelf devices are maintained in a stopped state, there is no risk that the shelf devices will move unexpectedly, and even if another path is selected, it will not move, so it is safe. That is, the operator can work safely by entering the passageway B after confirming that the reset lamp 28B is lit.

When the use of passage B is finished, operate the reset switch 14B of the shelf device 1B to reset the reset circuit 20.
When a signal is input to B, the reset circuit 20B inputs a reset signal 21B to the path control circuit 15B and the stop control circuit 23B, resetting all circuits to enable selection of another path.

In this embodiment, when the aisle switch 13B is operated and the shelves 1D and 1C are being moved, a shelf device other than the shelf device 1B, that is, a shelf device to which the other aisle control signal 37 is input, is moved. When either the passage switch 13 or the reset switch 14 is operated, the output terminal 19 of the passage control circuit 15
Alternatively, an abnormal stop signal is input from the output terminal 22 of the reset circuit 20 to the stop control circuit 23. Therefore, the moving shelf devices 1C and 1D stop at that position. During this stop, the lamp control circuit has
Since the stop signal 24 and the stop signal 25 are applied from the stop control circuit 23 and the normal stop signal 18 is not output, the reset lamp 28 starts blinking.

After the abnormal stop, when the reset switch of the shelf device whose switches 13 and 14 were operated is operated, the output of the abnormal stop signal is stopped and the shelf devices 1D and 1C restart. In this way, the shelf device can be quickly and easily stopped in the event of an abnormality.

The formation of the selected passage in this device is as described above, but in this case the stopping of 1C and 1D is done when they have moved to a defined position. That is, the width of the passage becomes a predetermined width, and the width of the passage is sufficiently wide, and it takes a considerable amount of time until all of the shelving apparatuses that have been moved come to a stop.

However, in reality, such a wide passage may not be necessary.

The normal stop device for the electric movable shelf device of the present invention has been developed in order to meet such demands. This will be explained with reference to the case where path B is selected in the state shown in FIG. In this case as well, first the aisle switch 13B of the shelf device is operated to input the first signal to the aisle control circuit 15B. When this signal is input, the movement command signal 16B and other signals are output from the aisle control circuit 15B as described above, and the shelf device 1
D and 1C start moving sequentially. Then, when a path B of an appropriate width is formed between the shelf device 1C and the shelf device 1B by moving the shelf device 1C, the path switch 13B is activated.
is operated again to send the second signal to the path control circuit 15.
B, this second signal is input to output terminal 1.
The output of the movement command signal from 6B is stopped, and the normal stop signal 18B is input to the stop control circuit 23B. Therefore, the stop control circuit 23B outputs a stop signal 24B to
D is stopped at that position, and the reset lamp 28B is lit to indicate that each shelf device is maintained in a stopped state and is safe.

In this case, when the output of the movement command signal 16A is stopped, the right command signal 33B is no longer applied to the shelf device 1C from the direction selection circuit 31B of the shelf device 1B, and the right command signal 33B is no longer applied to the shelf device 1D from the shelf device 1C. 33C also stops. Similarly, shelf device 1
Also at D, the output of the right command signal 33D is stopped, and the output of the start signal 38D to the shelf device 1C is also stopped. Therefore, the delay circuit 34D of the shelf device 1D resets its timer, and the shelf device 1B also stops sending the start signal 38B to the shelf device 1C. As a result, the shelf device 1C confirms that the start signal 38D from the shelf device 1D is no longer present, so the timer of the delay circuit 34C is reset.
That is, during the movement of the shelf devices 1C and 1D,
The circuit stops in exactly the same state as a normal stop.

When you have finished using aisle B or are in the middle of it,
When it is desired to further widen the passageway B, the passageway switch 13B is operated again and again, thereby outputting the movement command signal 16B in the same manner as the first signal, and the shelf apparatuses 1D and 1C start moving again. Each of these limit switches 6 contacts the actuator 8 and stops.

According to the normal stop device for the electric movable shelving device of the present invention as described above, the movement of the shelving device is performed by the first signal outputted by operating the passage switch of a specific shelving device in which a passage is to be formed. The movement command signal is stopped by a second signal outputted by operating the passage switch again when the command signal is output and the shelf device is moving and before the formation of a passage of a predetermined width is completed. Since a normal stop signal is output, it is possible to stop the moving shelving device mid-way and form a passageway with an arbitrary width narrower than the prescribed width passageway. Before forming the maximum width path that is limited by the limit switch and actuator, you can stop it normally when the minimum width necessary for the work is reached without waiting until it stops, such as when you are busy. This eliminates wasted time and improves work efficiency.

In addition, in the stopped state, the stop signal output based on the normal stop signal continues to be output regardless of the operation of any passage switch or reset switch of other shelving devices, and the stopped state of all the shelving devices is maintained. Therefore, there is no possibility that the shelf device will start up again due to unexpected operation by someone other than the operator. Note that this normal stop state means that when an aisle is selected and the shelving device is moving, operating any aisle switch or reset switch of any other shelving device other than the aisle switch and reset switch of a specific shelving device. This is a completely different state from the abnormal stop state where the limit switch and actuator work to stop the motor, and the circuit state can be the same as the normal stop state where the limit switch and actuator work to stop the motor. There is no need to reset the circuit.

Then, in a normal stopped state with a narrow passage formed, only when the passage switch of the specific shelving apparatus is operated again and again, a movement command signal similar to the first signal is output, and the shelving apparatus can be restarted. Therefore, a passage with a wider width can be formed, and the switch operation is simple.

In addition, the work can be carried out satisfactorily even in narrow aisles, and if you try to select another aisle after completing that task, you can reset all the circuits by operating the reset switch of that particular shelf device. This makes it possible to select another passage while a narrow passage is formed, thereby improving work efficiency. The means for inputting the first and second signals to the passage control circuit 15 need not be limited to contact pushbuttons, but may be arbitrary, such as inputting signals from a non-contact touch switch using a separately provided storage means. It can be done.

In this embodiment, when moving each shelf device,
Although the description has been given of the case where the shelves are started at slight time intervals, the present invention can also be applied to the case where a plurality of shelf devices are started at the same time.
