BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing the structure of a remote control type moving shelf stopping apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a shelf, and the leftmost shelf of the plurality of shelves 1 is fixed immovably on the floor, while the other shelves collectively converge together with the fixed shelf. And are movably arranged such that a work path can be formed between the shelves at a distance from each other. Each shelf 1 has a movable shelf control circuit board 22, and the fixed shelf at the left end has a general circuit board 23 including a circuit for receiving a signal transmitted by remote control, a circuit for determining a received signal, and the like. The side panel of each shelf 1 is provided with an operation panel 2 to which a passage formation command signal can be inputted by manual direct operation, and the left side fixed shelf side panel has a general operation panel 2a further having a power switch and the like. Is provided. The circled numbers in the figure indicate the passage numbers formed between the shelves.

FIG. 2 shows an example of a hand-held operation device (hereinafter referred to as a "transmitter") for remotely controlling the moving shelf device as shown in FIG. Each of the transmitters A, B, and C is a position data input operation member (hereinafter, referred to as a "path selection switch") 25 for selecting a signal corresponding to a path number in the movable shelf device and generating position data, and It has a reset switch 26 for resetting data, a power switch 28, and a stop switch 30 for stopping the movement of the shelf while the shelf is moving. In the example of FIG. 1, since the work passage number is up to 7, it is sufficient to have seven passage select switches 25, but the work passage number may be two or more digits depending on the specifications of the moving shelf device. In the example of 2, the passage selection switch 25 is constituted by a ten key. A signal corresponding to the passage selection switch 25 may be immediately generated when the passage selection switch 25 is selected and pressed. However, the passage selection switch 25 selected by the transmission switch 29 after the passage selection switch 25 is selected and operated. May be emitted. Each of the transmitters A, B, and C may emit radio waves, light, or the like as a medium, or may be operated by a worker without being mounted on a cargo handling device. Each of the transmitters A, B, and C may be connected to the mobile shelf device by a cable.

Reference numeral 27 denotes a moving shelf group for selecting a moving shelf group to be remotely controlled in the case of a moving shelf device having a plurality of moving shelf groups in which a plurality of shelves are movably arranged. Shows a selection switch. In the case of a mobile shelf device comprising a single mobile shelf group as shown in FIG. 1, the mobile shelf group selection switch 27 is unnecessary. Here, the passage selection switch 25, the reset switch 26, the moving shelf group selection switch 27, the transmission switch 29, and the stop switch 30 provided on the transmitter are collectively referred to as an operation member.
The stop switch 30 is referred to as a stop operation member.

Next, an example of a circuit configuration used in the present invention will be described. In FIG. 3, reference numeral 22 denotes the movable shelf control circuit board provided on each shelf. Each circuit board 22
The moving shelf control circuit incorporated in the above can be appropriately selected from the circuits used in known electric moving shelves, for example, the circuit described in Japanese Utility Model Laid-Open No. 56-163944. it can. Each of the shelves is provided with a motor 40 for driving each of the shelves, and the forward and reverse rotation and stop of the motor 40 are controlled by respective moving shelves control circuits, and the respective shelves are driven and stopped in the forward and reverse directions. Can be A limit switch 41 is connected to each circuit board 22. The limit switch 41 shown in FIG.
Is operated when each of the shelves 1 shown in FIG. 1 approaches an adjacent shelf 1, but when the absolute position of each of the shelves 1 is constantly detected by an encoder or the like, and moves to a predetermined movement limit position, The limit signal may be output based on the value of the encoder.

In FIG. 3, receiving circuits 35a, 35b,
35c receives the signals transmitted from the transmitters A, B, and C shown in FIG. When using radio waves as a medium, each receiving circuit 3
Each of 5a, 35b, and 35c has a demodulation circuit, and extracts a signal modulated together with a carrier. Further, each receiving circuit 35a,
The signals received by 35b and 35c are
Central processing unit (hereinafter referred to as “CPU”) 37 through 6
Is input to The CPU 37 is connected to each of the circuit boards 22 via an interface 38. CPU37
Is based on data input from each of the receiving circuits 35a, 35b, and 35c, and detects the operating state of each limit switch 41, and outputs the forward / reverse rotation command signal and the stop command signal of each motor 40 to each moving shelf control. The work path is input to the circuit board 22, and the movement and stop of each shelf 1 in the forward and reverse directions are controlled to form a work passage at a position corresponding to the command signal.

The CPU 37 may be a microcomputer including a read-only memory or a random access memory, or a personal computer. In short, each of the shelves 1 based on various input signals.
Any device can be used as long as it can be programmed so as to control the drive motor 40. Further, the portion of the CPU 37 may be a sequencer, or may be configured by a logic circuit so as to perform the same operation as the operation described later.

The CPU 37 is programmed so that the mobile shelf device performs the operation shown in FIG. First,
The signal from the transmitters A, B, and C shown in FIG. 2 is received by the receiving operation, and the apparatus waits for the reception of the received data. When the received data is sent, it is determined whether or not the data is position data, that is, whether or not the path selection switch 25 of the transmitters A, B, and C in FIG. 2 has been selected, and waits until the position data is input. . When the position data is input, the transmitter is determined, that is, from which transmitter the signal is issued, and then the rotation of the drive motor 40 of each shelf is controlled to form a work passage at a position corresponding to the position data. To start moving the shelves. As described above, the CPU 37 has the shelf running start unit as a functional block.

The receiving operation is performed even after the movement of the shelf is started, and it is determined whether or not there is received data. After the start of the movement of the shelf, there is received data before the shelf moves to a predetermined position and the limit switch 41 operates, and the received data is based on the operation of the stop operation member 30 shown in FIG. If there is, an emergency stop signal is input and the movement of each shelf 1 is stopped immediately on the spot. The emergency stop signal is output by operating the stop operation member 30 of at least one of the plurality of transmitters A, B, and C shown in FIG. As described above, the CPU 37 has the shelf movement stop unit as a functional block.

Since the above-mentioned shelf movement stopping portion is provided, for example, an operator is likely to be confined in a narrowing work passage, a cargo handling apparatus is likely to be pinched, and an article dropped from the shelf In the case where the shelf is likely to be caught, the stop operation member 30 of any one of the transmitters A, B, and C can be operated to stop the movement of the shelves in an emergency, thereby ensuring the safety of workers, It is possible to prevent the cargo handling device and the article from being damaged. Moreover, since the movement of the shelf stops even when the stop operation member 30 of any of the transmitters is operated, for example, when a worker in the work passage does not notice this when the work passage is narrowed, Even if the worker in the work passage does not notice that the article is falling inside, the other worker may operate the stop operation member 30 of the transmitter occupied by the other worker. Further, safety can be further improved, and breakage of the cargo handling device and the article can be more reliably prevented.
After the movement of the shelves is temporarily stopped as described above, the shelf is reset by operating the reset switch 26 of the transmitter or the like, and waits for the input of new position data.

After the shelf starts moving, if there is any received data including an emergency stop signal in the step of determining whether there is received data, the movement of the shelf may be stopped. FIG. 5 shows an example. In FIG. 5, if it is determined that there is received data in the step of determining whether or not there is received data after the start of moving the shelf, the shelf is moved without going to the step of determining whether the received data is an emergency stop signal. To stop. In this way, in a case where the movement of the shelf must be stopped urgently, such as when the worker is likely to be trapped in the work passage, the worker can perform at least one transmission including the stop operation member 30. It is sufficient to press at least one operation member (except for the power switch 28) of the machine, and the stop operation member 3
Since there is no need to select and operate 0, there is an advantage that the movement of the shelf can be reliably stopped even in an immediate case.

4 and 5, if there is no received data before the limit switch 41 operates after the shelf starts moving, the movement of the shelf is stopped when the limit switch 41 operates. As a result, a work space is formed at the designated position. When the shelf stops, the signal from the transmitters A, B, and C shown in FIG. 2 is received by the receiving operation, and the system waits for the reception of the received data. When the received data is sent, it is determined whether or not the data is a reset signal. If the received data is a reset signal, then it is determined whether or not the transmitter that transmitted the position data and the transmitter that transmitted the reset signal match. And reset only when they match. By resetting, the interlock is released and the shelf can be moved by the next position data input.

As described above, the interlock is released only when the position data and the transmitter that transmitted the reset signal coincide with each other, in consideration of safety. That is,
One transmitter transmits position data to form a work path, and when entering the work path, another worker operates another transmitter to move to another position. Can be formed, the safety of the workers in the already formed working path is threatened. In the case of the above embodiment, the worker in the work passage formed by operating one transmitter may operate the reset switch of the one transmitter after exiting the work passage after the work is completed. Since the work passage cannot be formed at another position, the safety of the worker in the work passage is ensured.
In the operation shown in FIG. 4, the step of determining the transmitter, that is, the step of determining which transmitter has transmitted the signal, and the step of determining whether the position data and the transmitter that has transmitted the reset signal match. Is not essential, and after forming a path by a signal from one transmitter, it may be reset by a reset signal from another transmitter.

In the embodiment described above, the shelf 1 moves in the direction perpendicular to the front face as shown in FIG. 1, but as shown in FIG. 6, the rail 52 is laid on the floor.
So that the shelf 51 moves in parallel with the front surface thereof, and a plurality of the rails 52 and the shelf 51 are arranged in parallel. When goods are not taken in and out, all shelves 51 are moved to the left or right side as shown in FIG. 6 so as to be dense, and when goods are taken in and out, only the corresponding shelf 51 is moved to the other side. The frontage is exposed, and articles are taken in and out from the exposed frontage. A stopper is provided at the movement limit position of each shelf 51, and a limit signal is output at the movement limit position. Such movement of the sliding movable shelf can be remotely controlled by a plurality of transmitters as shown in FIG. 2, and the operations as shown in FIGS. 4 and 5 are performed by the circuit configuration as shown in FIG. Can be made.

As shown in FIG. 7, depending on the moving shelf device, a plurality of moving shelf groups each including a plurality of shelves 1 arranged movably are arranged, and the movement of the shelves 1 is controlled for each group so that a work passage is formed. There are some that can be formed. In FIG. 7, reference numerals a, b, and c indicate moving shelf groups, respectively. The mobile shelf devices divided into a plurality of groups can be remotely controlled by a plurality of transmitters as shown in FIG. 2, and a circuit configuration as shown in FIG. 3 can be applied. Moving shelf group selection switches 27 provided on the transmitters A, B, and C shown in FIG. 2 are for selecting a moving shelf group to be remotely controlled by each transmitter. Symbols a, b, and c written on each moving shelf group selection switch 27 correspond to the moving shelf groups a, b, and c.

FIG. 8 shows an example of the operation of the multi-group mobile shelf apparatus. In FIG. 8, signals from the transmitters A, B, and C shown in FIG. 2 are received by a receiving operation, and the system waits for received data to be sent. When the received data is sent,
It is determined which of the plurality of moving shelf groups a, b, and c is selected for the data, and which of the plurality of transmitters A, B, and C is transmitted from which of the plurality of moving shelf groups is selected. Determine. Next, whether or not the data is position data, that is, the path selection switch 2
It is determined whether or not 5 has been selected. When the position data is input, the path number specified by the position data is determined, and each shelf is driven to form a work path at a position corresponding to the determined path number in the determined shelf group. The movement of the shelf is started by controlling the rotation of the motor 40.

The reception operation is performed even after the movement of the shelf is started, and it is determined whether or not there is received data. After the start of the movement of the shelf, there is received data before the shelf moves to a predetermined position and the limit switch 41 operates, and the received data is based on the operation of the stop operation member 30 shown in FIG. If there is, an emergency stop signal is input and the movement of each shelf 1 in the moving shelf group determined above is stopped immediately on the spot. The emergency stop signal is output by operating the stop operation member 30 of at least one of the plurality of transmitters A, B, and C shown in FIG. In this example, the CPU 37 has, as a functional block, a shelf movement stop unit that stops the movement of shelves in the group specified by the one transmitter with an operation signal of the stop operation member of at least one transmitter. I have.

Since the above-mentioned shelf movement stopping portion is provided, for example, when an operator is about to be confined in a narrowing work passage, any one of the transmitters A, B, and C is stopped. By operating the member 30, the movement of the shelves can be stopped urgently, whereby the safety of the worker can be ensured and the cargo handling device and the articles can be prevented from being damaged. Moreover, since the movement of the shelf stops even when the stop operation member 30 of any of the transmitters is operated, for example, when a worker in the work passage does not notice this when the work passage is narrowed, Even if the worker in the work passage does not notice that the article is falling inside, the other worker may operate the stop operation member 30 of the transmitter occupied by the other worker. Further, safety can be further improved, and breakage of the cargo handling device and the article can be more reliably prevented. After the movement of the shelves is temporarily stopped as described above, the shelf is reset by operating the reset switch 26 of the transmitter or the like, and waits for the input of new position data.

As shown in FIG. 9, when the shelf starts moving, there is received data, and in the step of determining whether the received data is an emergency stop signal, it is determined that the received data is an emergency stop signal. Alternatively, the movement of the shelves of not only the determined moving shelf group but also all the moving shelf groups may be stopped. In this example, the CPU 37 has, as a functional block, a shelf movement stop unit that stops the movement of the shelves in all groups by an operation signal of the stop operation member of at least one transmitter.

8 and 9, if there is no received data before the limit switch 41 operates after the shelf starts moving, the shelf movement is stopped when the limit switch 41 operates. Subsequent operations are the same as the operations shown in FIGS. 4 and 5, and a description thereof will be omitted. In the examples shown in FIGS. 8 and 9, the step of determining which transmitter has transmitted the signal and the step of determining whether the position data and the transmitter that transmitted the reset signal match each other are omitted. No problem.

In the examples shown in FIGS. 8 and 9, the operation after the reset signal is input may be changed to the operation shown in FIG. That is, when the reset signal is input, it is determined which moving shelf group is to be reset, and the group corresponding to the determined group is reset. This is to allow one transmitter or another transmitter to operate another mobile shelf group while one transmitter is operating one mobile shelf group. For example, during the formation of a path at a desired position by selecting a group by one transmitter, or after a path is formed, another group such as the b group is used by the one transmitter or another transmitter. Is selected so that a passage can be formed at a desired position. In the groups a and b, when the passage forming operation is completed, an interlock is applied, and the group cannot be moved unless it is released. Therefore,
Next, in order to enable the path forming operation again for the a group or the b group, the a group or the b group is selected by the one transmitter or another transmitter and a reset signal is transmitted. The moving shelf group determines which moving shelf group should be reset by the input reset signal, and releases the interlock of the corresponding moving shelf group. With respect to the mobile shelf group from which the interlock has been released, the path forming operation can be performed again by a signal from the one transmitter or another transmitter.

In order to perform such an operation, a reset signal can be transmitted separately from each transmitter for each moving shelf group. For example, a push button type group selection switch 27 as shown in FIG. 13 or a rotary switch type group selection switch 27 as shown in FIG.
When the reset switch 26 is operated after selecting a group with the group selection switch 27, a reset signal that is differentiated for each selected group is transmitted. Alternatively, as in a transmitter 80 shown in FIG. 25, a plurality of reset switches 83 corresponding to the respective moving shelf groups are provided, and by selectively operating these reset switches 83, the resets classified for each selected group are performed. A signal may be transmitted.

[0032] In the multi-group mobile shelf apparatus,
As shown in FIG. 10, after the shelf movement starts, before the shelf moves a predetermined distance and the limit switch operates, it includes an emergency stop signal, passage number data, transmitter identification data, moving shelf group identification data, and the like. The movement of the shelf may be stopped when all the data is input. In this example, the CPU 37 has, as a functional block, a shelf movement stop unit that stops the movement of the shelf with an operation signal of at least one operation member of at least one transmitter. In addition,
When transmitting a signal by light, the movement of shelves may be stopped in all the moving shelf groups by inputting a stop signal, or a stop signal by light is emitted toward the moving shelf group to be stopped. Alternatively, only the movement of the shelf of the group may be stopped.

As shown in FIG. 11, a plurality of pairs of rails 52 are provided.
8 to 10 by means of a plurality of transmitters even if a plurality of groups of sliding movable shelves comprising a plurality of shelves 52 movable in the frontage direction along are arranged.
Can be controlled in the same manner as in the example shown in FIG. 1, and in the case of an emergency, the moving shelf can be stopped by operating any of the transmitters. In FIG. 11, reference numerals a, b, and c denote moving shelf groups, respectively.
b and c have substantially the same configuration as the movable shelf device shown in FIG.

In the example shown in FIG. 12, a transmitter 55 called a handy terminal is used, a signal is transmitted from the transmitter 55 to a personal computer 60 wirelessly or by wire, and a plurality of mobile shelf groups a and b are transmitted by the computer 60. It is intended to be controlled. The transmitter 55 includes a passage selection switch 25, a reset switch 26, a moving shelf group selection switch 27, a stop operation member 30, and the like, similarly to the transmitter shown in FIG. 2, and is input by operating these switches and operation members. And a display 56 for displaying the data. A plurality of transmitters 55 are used. The signal transmitted from the transmitter 55 is transmitted to the computer 60.
The computer 60 controls the mobile shelf based on the received signal, as described above. However, a receiver is provided for each of the moving shelf groups a and b, and only the stop signal by the operation of the stop operation member 30 is received by the receivers of both the moving shelf groups a and b to stop the movement of the shelves. Good.

In order to stop the moving shelf urgently or to stop it at an arbitrary position, it is sufficient to operate at least one operation member or stop operation member of each transmitter as described above. However, depending on the situation, it may not be possible to know where the transmitter is immediately, and the stoppage of the shelf may be delayed. Therefore, as shown in FIG. 13, a spare transmitter 58 provided with a stop operation member 30 is provided, and the shelf can be stopped by operating the stop operation member 30 of the spare transmitter 58. You may. The spare transmitter 58 is desirably colored and shaped so as to be conspicuous in itself, and is preferably installed in a conspicuous position such as a cargo handling device. Stop operation member 30 of spare transmitter 58
May be connected in parallel with the stop operation member 30 of the parent transmitter by a code 59, or a standby signal may be directly transmitted wirelessly or by wire from the spare transmitter 58. When the spare transmitter 58 is provided, the stop operation member 30 may or may not be provided in the parent transmitter.

The transmitter may be as shown in FIG. In this example, a rotary switch type movable shelf group selection switch 62 is provided instead of the push button type movable shelf group selection switch 27 provided in the transmitter shown in FIG. The configuration of the other operation members is substantially the same as the example of FIG.
Note that a so-called digital switch may be used for the passage selection switch 25 and the moving shelf group selection switch 62.

The transmitter may be constituted by a palmtop computer 65 as shown in FIG.

A bar code reader 66 may be connected to the transmitter as shown in FIG. The transmitter itself in this example has the same configuration as the transmitter 55 shown in FIG. Barcode reader 66
Can read a bar code attached to an article taken in and out of the moving shelf, a bar code indicating the location of the shelf, and the like even when the distance is, for example, about 5 m.
5, the user can input inventory management data. The format of the barcode is not particularly limited, and is, for example, a barcode or a two-dimensional barcode in which data is recorded by dividing a plane into a grid pattern and painting each grid pattern with white and black. Alternatively, a stealth barcode that is invisible to the naked eye may be used, and a barcode reader 66 that can handle these formats is used. A reading device for numbers and characters may be used instead of the barcode reader 66. Alternatively, the movement of the shelf may be stopped by reading a bar code indicating stop using a bar code reader. The barcode reader may transfer data wirelessly.

In the example described so far, the moving shelf is stopped by operating at least one operation member or stop operation member of at least one transmitter. As described above, the operation may not be stopped when the reset switch of the transmitter requesting the movement start is operated, but may be stopped when an operation member other than the reset switch is operated. In FIG.
The steps up to the step of moving the shelves in the determined group are the same as those in the example shown in FIG. 8, but after that, if there is received data, and this received data is a transmitter that has not requested the start of shelving, an emergency stop is performed If the received data is a transmitter that has requested the start of the movement of the shelf, it is determined whether or not the received data is a reset signal. The movement of the shelf is stopped as requested, and the movement of the shelf is continued if the signal is a reset signal.

The operation in the case where there is no received data after the start of the movement of the shelf is the same as that of the previous embodiments, so that the description is omitted. Although the example of FIG. 17 is an example in which there are a plurality of moving shelf groups, it can be applied to a case of a single moving shelf group. In this case, the group determination step is unnecessary.

In the example shown in FIG. 18, when the same passage number data is input again from the transmitter requesting the start of movement of the shelf by designating the passage number, the shelf continues to move without stopping. It was made. That is,
If there is received data before the limit switch operates after the shelf movement starts, it is determined whether the received data is the transmitter that requested the start of movement, and if it is not the requested transmitter, an emergency stop is requested. If the received data is the transmitter requesting the start of the movement of the shelf, it is determined whether or not the received data matches the path number requested by the transmitter. If they do not match, the movement of the shelf is stopped assuming that an emergency stop has been requested, and if they match, the movement of the shelf is continued.

The operation in the case where there is no received data after the start of the movement of the shelf is the same as that of the previous embodiments, so that the description is omitted. Note that the example of FIG. 18 is an example in which there is a single moving shelf group, but the present invention can also be applied to a case where there are a plurality of moving shelf groups.

A general moving shelf device automatically determines the moving direction of a shelf by designating a passage number to be formed. However, depending on the moving method of the moving shelf device, the moving direction may be changed. There is a method in which a shelf is moved in a designated direction by designating a moving direction of the shelf after designating a shelf number to be set, and a work passage is formed at a desired position. FIG. 19 shows an example of a transmitter applied to this system. In FIG. 19, the path selection switch 25 designates a shelf to be moved here by a number. The transmitter has a left movement designation switch 71 and a right movement designation switch 72. By selecting and operating one of the designation switches 71, 72, the shelf designated by the passage selection switch 25 is moved. It moves left or right, and another shelf following it also moves. The transmitter also has a left-pointing arrow-shaped display unit 73 that is turned on by selecting and operating the designation switch 71;
A right-pointing arrow-shaped display unit 74 that is turned on by selecting and operating the designation switch 72 is provided. In addition, the same operation members as those in the example shown in FIG. 2 are provided. A plurality of such transmitters are used.

As a modification of the slide type movable shelf described in FIG. 6, two shelves 51 are movably installed along a pair of rails 52 as shown in FIG. In some cases, a plurality of shelves composed of two shelves 51 are arranged in parallel. In this moving shelf apparatus, as shown in the figure, two shelves 51 of each unit are separated from each other on the left and right sides. The shelf 51 is moved to the center thereof to expose the frontage of the shelf 51. As described above, a mobile shelf of this type also controls movement using a plurality of transmitters and operates at least one operation member or stop operation member of at least one transmitter in an emergency. For example, a stopping method and a stopping device for stopping the movement of the shelf can be applied.

As another example of the mode of use of the sliding movable shelf described with reference to FIG. 6, as shown in FIG. 21, usually, each shelf 51 is overlapped with the longitudinal center of the rail 52, and When an article is to be taken in and out, the corresponding shelf 51 is driven to the right or left to move the shelf 51 by a distance of about half of the frontage dimension to expose the frontage surface of the shelf 51 by about half. In some cases, articles are put in and taken out from the frontage. The stopping method and the stopping device according to the present invention can be applied to this example.

The moving shelf to which the stopping method and the stopping device according to the present invention are applied is not limited to a passage forming method. For example, when the position data is input, the first shelf to be moved starts moving first, and the subsequent shelves start moving sequentially, and all shelves to be moved start moving at the same time. There are a drive type, an eclectic type in which the next shelf starts moving at once after the first shelf to be moved starts moving, and the stopping method and the stopping device according to the present invention are applicable to any of these methods. , And can be applied to other types. Also,
As will be specifically described later, the present invention can also be applied to a multi-passage type moving shelf in which work passages can be formed at arbitrary plural places in a single moving shelf group.

In a mobile shelf for storing refrigerated items in a freezer or a mobile shelf for storing exhibits in a museum, etc.
From the viewpoints of freezing, antiseptic, insect repellent, fungicide, etc., a space is generally provided between the shelves 1 as shown in FIG. In addition, there is also a movable shelf device that forms a work passage required for taking in and out of articles between the corresponding shelf 1 and the adjacent shelf 1 when taking out and taking in the articles. The stopping method and the stopping device according to the present invention can be applied to such a moving shelf device. Means for providing a space substantially evenly between the shelves 1 is arbitrary, but one means is to recognize the current position of each moving shelf after the work of loading and unloading the articles, and to determine the square shelf from the recognized current position. There is a method of calculating the direction and amount of movement to be performed, and controlling to move in the determined direction of movement and by the determined amount of movement. As another means, there is a method in which all movable shelves are moved in one direction to converge by operating a predetermined switch, and each movable shelf is moved by a predetermined distance in a determination direction after a predetermined time by a timer operation. As still another means, all the movable shelves are moved in one direction by operating a predetermined switch to converge, and each movable shelf is moved by a predetermined distance in the determination direction by operating the predetermined switch again. There are ways.

As shown in FIG. 23, each of the transmitters A, B, C
A display element 75 composed of an LED or the like may be provided adjacent to each of the path selection switches 25, and the display element 75 corresponding to the selected path selection switch 25 may be turned on. Thus, there is an advantage that the selected passage selecting switch 25 can be confirmed. Similarly, a display element 76 such as an LED may be provided adjacent to each moving shelf group selection switch 27, and the display element 76 corresponding to the selected moving shelf group selection switch 27 may be turned on. Thus, there is an advantage that the user can check the selected moving shelf group selection switch 27.

A signal input method by the hand operation device can be selected arbitrarily. For example, a signal may be input by voice. In this case, when inputting a signal by voice, a switch is operated so that the voice input signal is not interfered between a plurality of hand control devices, or a worker's voice is output in advance for each hand control device. It is desirable to take measures such as registering and not accepting voices of other workers. However, when it is necessary to stop the movement of the shelf urgently, one of the hand-held operation devices recognizes this by inputting a shout such as "to rare", "stop", "dangerous", or "key". Then, the movement of the shelves should be stopped immediately. Alternatively, the movement of the shelf may be stopped when a sound of a certain sound pressure level or higher is input, or a sound of a whistle, whistle, musical instrument, or the like is recognized. The input of a signal such as a voice or a whistle also corresponds to “operating the operation member” in the claims. The voice input device may be provided with a manual stop switch.

In addition, a signal may be input by recognizing a color. For example, colors are assigned to each work space, a work space is formed at a position defined by the color by reading a specific color with an optical reading device, and a color of a shelf is read by reading a color indicating stop. Stop moving. If such a color recognition, a signal input method based on the above-described voice recognition, or a signal input method using the barcode reader is used, even a physically handicapped person can easily operate and even a physically handicapped person can use it. There is an advantage that operation becomes easy.

When the mobile shelf device is composed of a plurality of mobile shelf groups, as shown in FIG. 25, it is desirable to provide a transmitter display section 82 for distinguishing and displaying the used transmitters. For example, in an example in which the moving shelf is operated by a plurality of transmitters 80 that are distinguished as (A), (B), and (C) as in the example of FIG. 25, the transmitter used is determined. "A", "B" or "C" is displayed on the transmitter display section 82. By doing so, it is apparent at a glance which transmitter is operated to perform the passage forming operation and interlock is applied, and when trying to release the interlock to form a passage at another position, It is easy to know if resetting is necessary using the transmitter, which helps to streamline work. In the example of FIG. 25, a passage number display section 81 is provided adjacent to the transmitter display section 82. The passage number display section 81 displays the formed passage number. The display unit 82 or the display unit 81 selects an arbitrary one from among those that can be visually recognized, such as a light emitting diode (LED), a liquid crystal display panel, a display tube, a lamp, an electric bulletin board, and a mechanical display device. Can be adopted. In the example of FIG. 25, the display units 82 and 81 are provided only on one moving shelf, but the display units 82 and 81 may be provided on a plurality of shelves or all shelves.

[0052] Instead of the visual display, or in addition to the visual display, a voice may be displayed. Examples of what is displayed by sound include a buzzer, a chime, and a bell. These can indicate the discrimination of the transmitter or the passage number by continuous or intermittent sound. Also,
A synthesized voice may be emitted from a speaker using a voice synthesis IC or the like. The melody and timbre emitted from the speaker may be given meaning, so that the transmitter or the passage position may be distinguished. When sound is emitted from the speaker, a speaker having strong directivity may be used, and the sound may be emitted toward the operator while tracking the operator. In this case, there is an advantage that the information is transmitted only to the operator who needs the information, and an outsider cannot hear a harsh sound. As another means for transmitting information only to the operator, headphones or earphones (wireless ones are convenient) may be used. The audio display in this way is safe for people with poor vision, people with visual impairments, people with poor color vision, etc. Is transmitted,
Work efficiency can be improved. Further, instead of or in addition to the visual display or the sound display, the transmitter and the passage position may be distinguished by various scents.

In a mobile shelf that can be remotely controlled,
A mode switch for switching the operation mode between the remote control mode and the manual mode may be provided on the central control panel, for example, so that the movable shelf can be moved by directly operating the operation switch provided on the movable shelf directly. Conceivable. In this case, the moving shelf may be stopped by outputting a stop signal by manual operation during operation in the remote control mode, or a stop signal may be output by remote control during operation in the manual mode. May be stopped. It is also conceivable that the mobile shelf can be operated in both the remote control mode and the manual mode without providing the mode changeover switch as described above. In this case, regardless of the operation mode, the movement of the moving shelf is stopped when a stop signal is output during the movement of the moving shelf, or the movement of the moving shelf is stopped when any abnormal signal is output. It may be.

Each operation switch of the remote control transmitter or each operation switch provided on the movable shelf side may be a mechanical contact type switch or a touch panel type switch. In the case of a transmitter that emits a signal using radio waves as a medium, if the frequencies of the carrier waves of a plurality of transmitters are the same, interference occurs when signals are output from a plurality of transmitters at the same time, so mutually different frequencies are used. It is generally conceivable.
However, since it is rare that each transmitter emits a signal at the same time, and there is rarely interference,
It is possible to use transmitters having the same frequency and the same specifications. If a signal is transmitted from a plurality of transmitters at the same time and interference occurs, the mobile shelf is prevented from moving, and if it is moving, the movement is stopped to ensure safety.

The moving shelf to which the present invention can be applied is as follows:
The number of shelves is not limited to a plurality of movable shelves. The moving shelf may have only one shelf, and therefore may have no support and only a flat underframe.

A plurality of transmitters may be linked by a transceiver, a telephone, or the like, and an audio signal may be exchanged between the transmitters so that each operator can be informed of the overall operation status. Further, the whole operation status may be notified to each operator by a lamp, a numerical display unit, or the like provided in each transmitter or the like without using voice.

Next, an example in which the stopping method and the apparatus according to the present invention are applied to a multi-passage type moving shelf in which work passages can be formed at arbitrary plural places in a single moving shelf group. Will be described. FIG. 26 shows a case where a plurality of moving shelf groups a, b, c, and d are provided, and each moving shelf group a,
b, c, and d receive position data transmitted from the plurality of transmitters (A), (B), and (C), and form a work path (work space) at a designated position. In addition, in each of the moving shelf groups a, b, c, and d, a work path can be formed at another specified position while a work path is formed at the specified position. The external appearance of an example of a so-called multi-passage type moving shelf in which a work passage can be formed at a location is shown. In the case of a so-called multi-passage type moving shelf, it means that a work passage can be formed at a plurality of locations in one moving shelf group, including a case where there is only one moving shelf group, and FIG. As shown in the example, there is a plurality of moving shelf groups, and a work path can be formed at a plurality of positions in each moving shelf group. Also,
Some of the moving shelf groups among the plurality of moving shelf groups may be of the multi-passage type.

FIGS. 27 and 28 show an operation example in which the stopping method and the stopping device of the present invention are applied to the multi-passage type moving shelf. The example illustrated in FIG. 27 is substantially the same as the example illustrated in FIG. 8. Basically, the movement of the shelf is started in the determined moving shelf group based on the received position data, and after the movement is started. It is also determined whether there is received data, and if there is received data before the shelf moves to a predetermined position and the limit switch operates, and if the received data is emergency stop data, it is determined. This is for urgently stopping the movement of the shelves in the moving shelf group. The example shown in FIG. 27 is different from the example shown in FIG. 8 in that when the received data after the movement of the shelf is stopped by the operation of the limit switch is not reset, the process returns to the group determination step again and moves from the received data. The shelf group is determined, the transmitter is further determined, and if the received data is position data, the passage number is determined, and the movement of the shelf is started in the determined moving shelf group to form a work passage. It is a point. Therefore, in the example shown in FIG. 27, work passages can be formed at a plurality of locations within one moving shelf group.

In the example shown in FIG. 27 described above, when one work path is formed at a designated position and then a work path is formed at another position, it does not matter which transmitter the transmitter is. Therefore, for example, after forming a work passage at a designated position of the moving shelf group a using the transmitter (A),
Using the transmitter (C), another position of the moving shelf group a can be designated to form a work path. According to this method, a work path can be formed at an arbitrary position in an arbitrary moving shelf group using an arbitrary transmitter.
It can be said that this system focuses on streamlining the work of dispensing goods.
However, after one transmitter specifies one moving shelf group and forms a work passage, in the moving shelf group,
Only when position data is input from another transmitter, a work path can be formed at another position while the work path is formed. FIG. 28 shows an example of this. After the movement of the shelf is stopped by the operation of the limit switch, if the received data is not a reset signal, whether the transmitters match, that is, the transmitter that transmitted the first position data It is determined whether or not the transmitter and the transmitter that transmitted the next position data match. If not, the process returns to the group determination step again. Further, the transmitter is determined. The number is determined, and the movement of the shelf is started in the determined moving shelf group to form a work passage.

Contrary to the example shown in FIG. 28, after the movement of the shelf is stopped by the operation of the limit switch, if the received data is not a reset signal, it is determined whether or not the transmitters match, and the first position data is determined. Only when the transmitter that has transmitted and the transmitter that has transmitted the next position data returns to the group determination step again, further determines the transmitter, and if the received data is position data, determines the path number. Alternatively, the work path may be formed by starting the movement of the shelf in the determined movable shelf group.

In the moving shelf apparatus of the multi-passage type described above, when a work passage is formed at one designated position, the work passage is maintained unless reset, and the work passage can be formed at another position. In addition, a movable shelf facing the work passage is interlocked to be immovable. Therefore, as shown in FIG. 26, an interlock indicator 85 is provided on the side surface of each movable shelf 1 constituting each group, and the interlock indicator 85 of the movable shelf that has been interlocked is turned on to interlock. It is desirable to be able to clearly recognize from the outside of the moving shelf on which the lighting is applied. Interlock indicator 8
The display method according to 5 is arbitrary, and may be a light-emitting display such as a lamp display or an LED display, a mechanical display, or a display by voice.

As described above, in the multi-passage type moving shelf device, when a work passage is formed at one designated position, the movable shelf facing the work passage is interlocked immovably unless reset. The reset may be performed only by a reset command from the transmitter used to form the work path at the one designated position, or may be performed by a reset command from any transmitter. Is also good.

In the multi-passage type moving shelf device, in order to form a working passage at one designated position and then form a working passage at another position, the moving shelf is automatically determined by judging a direction having a margin for transition. The stopping method and the stopping device according to the present invention can be applied to such a system. Also, as shown in the example shown in FIG. 19, switches 71 and 72 for specifying the direction of movement to each transmitter are provided, and switches 71 and 7 are determined by the worker.
Alternatively, the user may select 2 to move the movable shelf in a direction where there is room for transition.

In the multi-passage type moving shelf device, it is necessary to form a large transition allowance in advance so that a multi-passage can be formed, and each work passage is limited by the large transition allowance. It must be formed within the range. Therefore, it is necessary to detect the width of the formed passage and stop the movement of the movable shelf when the passage width reaches a certain width. As the passage width detecting means, an appropriate one may be selected from well-known means and employed. For example, adjacent moving shelves may be connected by a swing arm, and the width of the passage may be detected by the opening angle of the swing arm according to the width of the passage, or an optical detection device using light or a laser beam. Alternatively, a mechanical detection device in which a rod having a protrusion or a recess is extended from one of the adjacent shelves, and the protrusion or the recess is detected by a detection switch provided on the other shelf.

As described with reference to FIG. 22, in order to make the air-conditioning conditions of the articles stored in the respective shelves uniform, spaces are generally provided between the respective shelves 1 so that the articles are stored in the respective shelves. A moving shelf device in which the air-conditioning conditions for articles are made uniform, and a work path required for taking articles in and out is formed between the corresponding shelf 1 and the adjacent shelf 1 when articles are taken in and out. There is. It is still more effective if the moving shelf device is of a multi-passage type. That is, since the multi-passage type moving shelf has a large transition allowance as described above, a relatively large space can be provided almost evenly between the shelves, and the air conditioning conditions can be made uniform. Because it is easy. In addition, since a relatively large space can be provided between the respective shelves as described above, the space between the respective shelves can be used as a space for performing a certain work, for example, an inventory work, and the efficiency can be improved. There is also an advantage that a complicated operation can be performed. In addition, when used as display shelves in libraries, museums, museums, etc., depending on the progress of exhibition work,
Alternatively, since a relatively large space and a small space can be arbitrarily formed according to the wishes of the viewer, work efficiency can be improved and the wishes of the viewer can be met.

As is clear from the above description, the multi-passage type moving shelf also has a shelf moving start portion and a shelf moving stopping portion. That is, when the received data is position data, the movement of the shelf is started by controlling the rotation of the drive motor of each shelf to form a work path at a position corresponding to the position data. CPU 37 shown in 3
Have a shelf running start unit as a functional block.
If there is received data between the start of the movement of the shelf and the movement of the shelf to the predetermined position and the operation of the limit switch, and if the received data is an emergency stop signal, the movement of the shelf is stopped. An emergency stop is performed at the site. For example, the CPU 37 shown in FIG. 3 has a shelf movement stop unit as a functional block.

The emergency stop signal is output in the same manner as in the previously described embodiment. For example, the output may be made by operating the stop operation member 30 of at least one of the plurality of transmitters A, B, and C shown in FIG. 2, or by operating another operation member. May be output. Further, in the case of a plurality of moving shelf groups, the movement of shelves of the determined group may be stopped or the movement of shelves of all groups may be stopped according to the output of the emergency stop signal. You may do so. In addition, an emergency stop operation similar to the emergency stop operation shown in FIGS. 4, 5, 8, 9, 10, 17, and 18 can be performed on a multi-passage type moving shelf.

Since the installation space of the moving shelves may be divided by pillars of a building, etc., the moving shelves are also divided into a plurality of pieces to avoid the pillars of the building, etc. There is a split type movable shelf which is controlled integrally as a movable shelf. The split type movable shelf has a motor as a drive source in each of the divided shelves, but controls such as movement and stop are integrally controlled by the same control circuit. The split type movable shelf can also be configured in a multi-passage type, and the stopping method and apparatus of the present invention can be applied to the split type multi-passage type movable shelf.

In the case where an emergency stop signal is transmitted to each group in a mobile rack in which a plurality of mobile rack groups are arranged, it has conventionally been considered that the main controller serially transmits the signal to each group. According to
Since an emergency stop signal can be sent to each moving shelf group at the same time in parallel, the moving shelves can be stopped all at once in an emergency, and the line is not blocked.
Reset after stopping is quick, and resumption of movement can be quickly performed.

[0070]

According to the first aspect of the present invention, in a multi-passage type mobile shelf, when the shelf is moving, any operation member of any hand-operated device can be used to stop the shelf. From, for example, when the worker in the work passage does not notice when the work passage is narrowed, or when the worker in the work passage does not notice that the article is falling in the work passage However, it is only necessary for the other operator to operate any of the operation members of the hand-held operation device occupied by the other operator, and it is possible to improve safety in the case of promptness, and to improve the cargo handling device and the article. Can reliably be prevented from being damaged.

According to the second to fourth aspects of the present invention, in the multi-passage type moving shelf, when the shelf is moving, any operation device can be used, so that the operating member or the stop operating member can be operated. Since the shelves can be emergency-stopped, the same effects as those of the first aspect can be obtained.
