A more specific structure of the control units 61, 62, 63 and 64 will be described with reference to FIG. In FIG.
The central control panel 23 includes a plurality of wireless operation devices 11, 12, 1
3, the receiving unit 16 that receives the signal transmitted from the control unit 3 and various determinations such as which block the operation signal received by the receiving unit 16 is targeted for, or which passage is targeted for A signal discriminating section 26 that operates and a main board 27 to which the signal discriminated by the signal discriminating section 26 is input
And the dispersion substrate 28. The centralized control board 23 is provided on one of the movable shelves constituting a large block of the plurality of blocks, and the distributed control board 24 having the dispersed substrate 29 is provided on the other movable shelves. Further, in blocks other than the main block, a main control board 25 and a distributed control board (not shown) similar to the distributed control board 24 are provided for each moving rack. The main control board 25 is a distributed substrate 30
And a main substrate 31. A discrimination signal from the signal discriminating unit 26 is input to each of the dispersion substrates 29, 30 and the main substrate 31.

The control system described above may be mainly composed of a microcomputer, or may be mainly composed of a digital IC or the like. As the wireless transmission / reception method, any method may be adopted. For example, the modulation method may be FM modulation or AM modulation. The signal format is digitally encoded (PC
It is desirable to use M) signals.

The operation of the embodiment described above will be described with reference to FIG. First, the remote / manual switching unit 20 shown in FIG. 1 determines whether the remote operation mode is selected by the selector switch of the remote / manual switch panel 39 shown in FIG. 4 or the manual direct operation mode is selected. When the manual direct operation mode is selected, the movable shelves are moved by directly operating the open switches of the operation panels 36 and 38 shown in FIGS. 4 and 5, and a working passage is formed at a desired position. The movable rack can be stopped at any position by operating the stop switch as needed. Such a manual direct operation may be performed by operating any open switch in any block, and can be operated independently in any block. Since the operation at the time of manual operation is the same as in the case of the conventional general electric moving rack device, the description thereof will be omitted.

When it is judged in the remote operation mode in the above-mentioned step of judging whether it is in the remote operation mode,
That is output, and then, in each determination step of a transmission A request, a transmission B request, and a transmission C request, from one of the plurality of wireless operation devices A, B, and C, the mobile shelf is moved. Wait for the operation request. When an operation request is issued from any of the wireless operation devices, it is determined in the next step which one of the wireless operation devices A, B and C has issued the mobile rack operation request. Next, in the target passage reading comprehension processing routine, it is determined which passage the operation signal is a target signal, and in the target block reading comprehension processing routine, it is determined which block the operation signal is a target signal. Determine. Such a determination operation is performed by the target passage determination unit 17 and the target block determination unit 18 shown in FIG.

Next, the process proceeds to the step of determining whether the target block determined by the target block reading comprehension processing routine is in the remote mode. If the target block is in the remote mode, the next target block is operating. Go to the decision step. The determination as to whether the target block is in operation is performed by the target block in-operation determination unit 19 shown in FIG. If the target block is not operating, the process goes to the rack operation output processing routine, and the open signal is output to the target block. This open signal is a signal similar to that in the case of direct manual operation, whereby the moving shelf of the target block moves and a working passage is formed at a desired position based on the operation signal transmitted from the wireless operation device. To be done. If it is determined in the step of determining whether the target block is in operation, it means that the block is being operated by another wireless operation device. Only the operation by the device is possible, the other wireless operation devices cannot be operated, and an error is displayed.

Next, the procedure goes to the step of determining the interlock release. In this step, it waits until the interlock is released, and when the interlock is released, it goes to the next interlock release processing routine. Here, the interlock means that when a passage forming operation in one block is being performed by an operation signal from one wireless operating device, another wireless operating device cannot perform the passage forming operation in that block. And when the passage forming operation in one block is being performed by the operation signal from one wireless operation device, the wireless operation device must be restrained so that the passage forming operation in another block cannot be performed. Further, when the passage forming operation in one block is performed by the operation signal from one wireless operation device, the passage can be formed in another position of the block by overlapping with the wireless operation device. Including restraint so that it cannot be done.

Therefore, a wireless operation device other than the wireless operation device transmitting the operation signal for one block enables the passage forming operation in the block, and the wireless operation device transmits the operation signal for one block. The operating device enables the passage forming operation in another block, and further, the wireless operating device transmitting the operation signal for one block can be overlapped to form a passage in another position of the block. In order to do this, it is necessary to release the interlock. The interlock is released by operating the passage reset switch 53 shown in FIG.
The interlock circuit 21 shown in FIG.

The interlock release processing routine is
In short, the interlock release operation is actually performed by inputting the interlock release signal. Next to the interlock release processing routine, the process goes to a step of determining whether or not a request stop command is issued. If a request stop command is issued, a request stop process is performed and a series of operations is completed.

According to the embodiment described above, the movable rack is divided into a plurality of blocks so that each block can be operated by a plurality of wireless operation devices. Therefore, each block can independently perform the passage forming operation. By doing so, it is possible to carry out the work of putting in and taking out the articles in parallel at the same time, which makes it possible to improve the work efficiency. In addition, when the target block in-motion determining unit 19 determines that the block is in operation, the wireless operation device other than the wireless operation device operating the block determined to be in operation cannot perform the passage forming operation in the block. Therefore, when working by entering the passage formed in one block by the operation of one wireless operation device, the movable rack of the block does not move abruptly by the operation of another wireless operation device, Safety is secured.

In the operation described with reference to FIG. 8, the judgment as to whether or not the mode is the remote operation mode is made based on one mode changeover switch. However, when the remote / manual changeover switch is provided for each block, As shown in FIG. 10, it is determined whether or not each block is in the remote operation mode, and a signal indicating that the block is in the remote operation mode is in the remote mode. The subsequent operation is the same as the operation shown in FIG. If a remote / manual switch is provided for each block in this way, only the block that has been switched to the remote mode can be operated by the wireless operation device, and the block that has been switched to the manual mode can be operated manually. Therefore, it is possible to switch the mode for each block according to various conditions such as whether the article is taken in and out by a forklift or the like, or manually, so that it is efficient according to various conditions. You can do the work.

In the example shown in FIG. 7, the wireless operation device has a passage reset switch as an interlock releasing operation unit.
Although they are provided one by one, as in the example shown in FIG. 11, the wireless operation device 11A may be provided with the passage reset switches 80 as a plurality of interlock release operation units.
The passage reset switch 80 is provided corresponding to each block. In the example of FIG. 11, R1 and R corresponding to 5 blocks
Five passage reset switches 80 of 2, ..., R5 are provided. A plurality of wireless operation devices having the same configuration as the wireless operation device 11A are provided. In this way, if each wireless operation device is provided with a plurality of passage reset switches corresponding to each block, each wireless operation device can be operated by selecting a plurality of passage reset switches 80. The interlock of can be selectively released for each block.

Therefore, when the passage forming operation is performed for one block by one wireless operation device, interlock is applied to the operation of the block, and the passage reset corresponding to the block is performed in the wireless operation device. Unless the switch is operated to release the interlock for the block, the passage forming operation cannot be performed for the block by not only the wireless operation device but also another wireless operation device. Further, the passage forming operation can be performed by the wireless operation device and the other wireless operation device, provided that the other blocks are not interlocked.

As shown in the example of FIG. 11, when each wireless operation device is provided with a plurality of passage reset switches corresponding to each block, one wireless operation device targets one block for passage formation operation. The interlock related to the block, which is applied by performing the above procedure, may be released by another wireless operation device. By doing so, even if one wireless operating device becomes unusable due to failure or power consumption, another wireless operating device will perform a passage forming operation for that block. You can
In addition, when there is an urgent need, there is an advantage that the passage forming operation can be performed on the block by another wireless operating device.

It is sufficient that the movable rack is divided into a plurality of blocks, and other arrangement relations of the movable rack are irrelevant. Therefore,
A block may be configured by a plurality of movable shelves arranged in the traveling direction, a plurality of blocks may be arranged in a direction orthogonal to the traveling direction, and each block may be operated by a wireless operation device. . In addition, a block is composed of a plurality of movable shelves arranged in the traveling direction, and the movable shelves are divided into a plurality of parallel shelves in a direction orthogonal to the traveling direction and arranged side by side, and the movable shelves are arranged side by side in a direction orthogonal to the traveling direction. May be moved simultaneously by an operation signal from the wireless operation device. 12 to 15 show an example of the arrangement relationship of such movable shelves.

In the example of FIG. 12, a block is composed of a plurality of movable shelves arranged in the traveling direction, a plurality of blocks are arranged in a direction orthogonal to the traveling direction, and each block is wirelessly operated. It is designed to be operated by the device. Reference numerals 1a, 1b and 1c indicate blocks arranged in a direction orthogonal to the traveling direction. A plurality of movable shelves forming each block run along rails 35 laid on the floor of the building. With such an arrangement relationship, even if the installation space of the moving shelf device is divided by the pillars 81 of the building or the like, it is possible to arrange blocks each including a plurality of moving shelves in the divided space. There is an advantage that each block can be operated independently.

The example of FIG. 13 is the same as the example of FIG. 12 in appearance, but a block is composed of a plurality of movable shelves arranged in the traveling direction, and the movable shelves are arranged in a direction orthogonal to the traveling direction. The movable shelves, which are divided into a plurality of pieces and are arranged in parallel in a direction orthogonal to the traveling direction, differ from the example of FIG. 12 in that they are simultaneously moved by an operation signal from a wireless operation device. In FIG. 13, reference numerals 1a, 1b, and 1c represent movable rack groups belonging to one common block. Although a plurality of movable shelves arranged side by side in the direction orthogonal to the traveling direction may be originally configured as continuous ones, in order to install the movable shelving device in the space divided by the pillars 81 and the like, the individual moving shelves are individually moved. The shelves are divided into a plurality of pieces in a direction orthogonal to the traveling direction and are arranged side by side. Then, the plurality of movable shelves arranged side by side in the direction orthogonal to the traveling direction simultaneously move in response to an operation signal from the wireless operation device. The hatched movable shelves in FIG. 13 indicate a set of movable shelves that are divided into a plurality of pieces and are juxtaposed in the direction orthogonal to the traveling direction.

In the example shown in FIG. 13, the movable shelves arranged in the traveling direction and divided in the direction orthogonal to the traveling direction and juxtaposed side by side have the same size and the same shape. The size and shape of each movable rack may be changed accordingly. For example, as shown in FIG. 14, even if the installation space of the moving rack device is divided by the pillar 81, if the pillar 81 is not within the moving range of the moving rack, the moving rack installed in that space is orthogonal to the traveling direction. It is not necessary to divide the movable rack in which the columns 81 are present within the movement range in the direction orthogonal to the traveling direction. In FIG. 14, reference numerals 83a and 83
Reference numerals b and 83c and reference numerals 85a, 85b, and 85c denote movable shelves divided in a direction orthogonal to the traveling direction, and reference numeral 84 denotes a movable shelf that is continuous in a direction orthogonal to the traveling direction. The movable shelves divided in the direction orthogonal to the traveling direction move at the same time according to an operation signal from the wireless operation device. In FIG. 14, the hatched movable shelves indicate a set of movable shelves that are divided into a plurality of pieces and are juxtaposed in the direction orthogonal to the traveling direction.

The example shown in FIG. 15 is in line with the example shown in FIG. 14, but a single space is provided in the extra space formed between the column 81 and the movement limit of the movable rack continuous in the direction orthogonal to the traveling direction. The movable shelves 86a, 86b and 87s, 87b are arranged. A single-type movable rack is one in which the article storage space is provided only on one side, and most of the other movable racks are double-type movable racks in which the article storage spaces are provided on both sides. The single-type movable shelves 86a and 86b are integrally formed with the multiple-type movable shelves 83a, 83b, and 83c in a direction orthogonal to the traveling direction, and the single-type movable shelves 87a and 87b.
The b is integrally formed with the movable shelves 90a, 90b, 90c in a direction orthogonal to the traveling direction. Figure 15
In FIG. 8, reference numerals 88a, 88b, 88c indicate a plurality of movable shelves that are divided in the direction orthogonal to the traveling direction because the columns 81 are present in the movement range, and are single-type movable shelves.

If any wireless operation device once performs a passage forming operation on one block and then any wireless operation device attempts to perform a passage forming operation on the same block, an interlock is performed. The passage may be formed without performing the releasing operation. The control operation in this case is shown in FIG. In FIG. 16, when it is determined that the target block is in operation, it is determined whether the target block is the same as the previous target block. If not, an error message is displayed. Then, rack operation output processing is performed to form a passage at a designated position. Next, when one of the wireless operation devices is operated to form a passage in another block, the interlock release operation is performed. In the interlock release determination step, it is determined whether or not the interlock release operation is performed, and the operation according to the determination is performed.

In the operation shown in FIG. 8 described above, it was not possible to simultaneously designate a passage position in a plurality of blocks by one radio operating device to form a passage at that position, but if the block is not in use, It may be possible to perform the passage forming operation in one block by one wireless operation device and simultaneously form the passage in another block. The operation in this case is shown in FIG. In FIG. 17, when it is determined in the step of determining whether the target block is in operation, the target block is not in operation, rack operation output processing is performed, and it is determined that the interlock is released in the target block. To form a passage at a designated position.

Further, the interlock of the passage formed by one wireless operation device may be released by another wireless operation device. FIG. 18 shows the operation in this case. In FIG. 18, in the remote mode, it is arranged to judge whether or not there is a mobile rack operation request from the wireless operation device and go to the target passage decoding processing routine. From which wireless operation device the mobile shelf operation request has been issued. No judgment is made. Therefore, the interlock of the passage formed by one wireless operation device can be released by another wireless operation device, and therefore, any wireless operation device can perform the passage formation operation.

In the example of the wireless operation device shown in FIGS. 7 and 11, a plurality of passage opening switches are arranged in a matrix corresponding to the blocks and passages, but the blocks and passages may be selected by the numeric keypad switch. However, it is also possible to provide a digital switch for each block,
By selecting one digital switch and setting a numerical value, a passage may be formed at a desired position in a desired block.

Further, in the example shown in FIG. 9, the signals are received by the receiving units respectively corresponding to the plurality of wireless operation devices, but the signals from the plurality of wireless operation devices are handled by one multi-compatible device. You may make it receive by a receiving part. The wireless operation device may be operated not only on the forklift but also on a stacker crane, an overhead traveling crane, or other cargo handling device. The power source of the wireless operating device may be a primary battery or a secondary battery, or when operating from a forklift or other cargo handling device, the power source of these cargo handling devices may be used. Further, a receiving unit corresponding to each of the plurality of wireless operation devices may be provided for each moving shelf block. Therefore, if there are five mobile shelves in three wireless operation devices, there will be a total of 15 receivers.

In the above embodiment, when the passage forming operation in one block is being performed by the operation signal from one wireless operation device, the passage reset switch of the wireless operation device is operated to release the interlock. If this is not done, it will not be possible to perform a passage forming operation at another position for that block, but even if the interlock is not released, that block will be targeted by the operation signal from the wireless operation device. Alternatively, the passage forming operation may be performed at another position. Even in this case, one wireless operating device is often used continuously by one worker, and unless another wireless operating device performs an interlock release operation, another wireless operating device does not operate in the block. Since the passage forming operation is impossible, the safety is secured.

In the present application, the movable shelf includes not only a form in which a plurality of article storage spaces are formed on a dolly but also a flat form in which only the dolly is formed. As the wireless signal between the wireless operation device and the receiving unit, not only radio waves but also light, ultrasonic waves, or the like may be used.

Although it is necessary to send and receive a traveling direction signal and other control signals between a plurality of shelves constituting each block, the control signals are sent and received between the shelves.
As described in Japanese Patent Publication No. 804, it may be performed by using an optical signal transmitting means. In this way, the cable for transmitting / receiving the control signal can be omitted.

The movable shelf to which the present invention is applicable is not limited to the one that moves in the direction orthogonal to the front surface, but moves in the direction parallel to the front surface as indicated by reference numeral 91 in FIG. It may be a mobile shelf. In FIG. 19, reference numeral 92 indicates a rail for guiding the movement of the movable rack 91.
A plurality of movable shelves 91 constitutes one block, and the plurality of blocks are continuously arranged. Even with such a moving rack device, when the moving rack is moved, the front surface of the moving rack and the other moving rack adjacent to the moving rack is opened, and articles can be taken in and out. Even in such a moving rack device, the passage forming operation can be performed by the wireless operation device for each block unit.

Each moving rack may be provided with a safety bar which detects when a person, a foreign substance, or the like is caught between the racks and stops the movement of the moving rack or the like. 3, FIG. 12 to FIG.
In the movable shelf shown in (1), a safety bar may be provided on the front side of the shelf plate or underframe so that the movable shelf stops when the safety bar facing the closing passage comes into contact with a person or a foreign object. In addition, in the mobile shelf shown in FIG. 19, safety bars are provided on the operation panel surface, that is, on the left and right sides when viewed from the front side, and when the mobile shelf is moving, the safety bar of the one where the mobile shelf is pulled out. The mobile shelf should stop when a person or a foreign object touches it.

[0047]

According to the first aspect of the present invention, the movable rack is divided into a plurality of blocks, and the plurality of wireless operation devices can be operated for each block. Therefore, each block independently has a passage. By performing the forming operation, the articles can be taken in and out in parallel in each block at the same time, which can improve the efficiency of the work. Further, when the target block in-operation determining unit determines that the block is in operation, a wireless operation device other than the wireless operation device operating the block determined to be in operation does not allow the passage forming operation in the block. As a result, when one wireless operation device is operated to enter the passage formed in one block to perform work, the operation of another wireless operation device does not cause the movable shelf of the block to move abruptly. Sex is secured.

According to the second and third aspects of the invention, when the passage forming operation is performed on one block by the operation signal from one wireless operation device, the wireless operation device performs the interlock releasing operation. As long as there is no passage, the passage forming operation in other blocks cannot be performed.
It is possible to prevent the passage forming operation from being accidentally performed in another block by the operation of the wireless operation device that has already performed the passage forming operation, and ensure safety. According to the invention of claim 4, by selectively operating a plurality of interlock release operating portions provided in each wireless operation device, the interlock applied by the operation of the wireless operation device is selected. Since the wireless operation device can perform the passage forming operation for any block, the article can be efficiently put in and taken out while ensuring safety.

According to the fifth aspect of the present invention, the movable shelves are divided into a plurality of pieces in the direction orthogonal to the traveling direction and arranged side by side, and the movable shelves arranged in the direction orthogonal to the traveling direction are separated from the wireless operating device. Even if the installation space of the mobile shelf device is divided by the pillars of the building, etc., the mobile shelf devices can be installed effectively by using the divided space, and the divided movement Since many of the control circuits on the shelf can be shared, there is an advantage that the configuration of the control circuit does not become so complicated.

According to the invention described in claim 6, since the mobile shelf device can be switched between the remote operation mode by the wireless operation device and the direct operation mode by manual operation by switching the remote / manual switching unit, various operations can be performed. There is an advantage that the mode can be selected according to the mode.
