Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a parts management device for cargo handling operations by manned cargo handling vehicles.

[Conventional technology] Traditionally, work involves memorizing the locations of loads, pallets, packets, parts, etc. in your head based on past cargo handling operations, and then performing cargo handling operations based on that memory. Ori,
Although there were work instructions from the manager, the actual work was carried out at the discretion of the worker.

[Problem to be solved by the invention] Conventionally, cargo handling work has been carried out based on the worker's memory, so the number of parts handled increases so much that it becomes impossible to remember all of them, or other workers may change the storage location due to convenience. If the parts were moved without permission, or if the person in charge of the work was absent, it would become impossible to know where the parts were, and work efficiency would suffer.

Furthermore, if the worker is unfamiliar with the work area, even if he or she receives work instructions, he or she may not completely know where to place the parts, resulting in poor work efficiency.

Therefore, Ganto Honro uses communication means to give work instructions to the work vehicle and at the same time displays map information related to the location of the parts to be worked on, and also updates and stores the work contents performed each time the work is completed. In order to improve the work efficiency by keeping the work in progress, we requested a cargo handling work management device in Japanese Patent Application No. 01-248918, but the work vehicle developed a defective condition and it became impossible to carry out the work.

A cargo handling work management device comprising: a group of sensors for detecting various defective states of the cargo handling vehicle; means for outputting the detected various faulty states to the screen display section; and means for transmitting a work impossible signal to a central management section. The present invention is characterized in that the management section of the cargo handling vehicle side is provided with a display means for displaying the transmitted work disable signal, and the central control section side is provided with a display means for displaying the transmitted work disable signal.

According to the present invention having the above-mentioned configuration, if a defect occurs in the work vehicle, not only the worker but also the central management section will be aware of the defective state.

[Example] Examples of the present invention are shown in FIGS. 1 to 7.

FIG. 1 shows a block diagram of an embodiment of the present invention. Reference numerals 1 to 5 are installed on the central management unit side, where 1 is a screen display unit such as a CRT, 2 is a parts information unit, 3 is a control unit (operation will be described later), and 4
5 is an input unit such as a keyboard, and 5 is a modem for communication.

Further, numerals 6 to 11 are installed on the side of a cargo handling vehicle such as a forklift, and 6 is a communication modem, 7 is a map information section, 8 is a control section (operation will be described later), 9 is an input section such as a keyboard, 10 Reference numeral 11 indicates a display unit such as a liquid crystal or CRT, and 11 a group of sensors for detecting defective conditions such as engine oil pressure, brake fluid level, charging system, and remaining fuel level.

Next, the map information section 7 will be explained with reference to FIG. This map information section 7 includes, for example, an overall map (map number, 0) representing the entire work area of a cargo handling vehicle, a group of enlarged maps of this one section (map numbers, 1 to 9), and further information of these one section. Detailed map group (Map No. 11-19.21-29...
- Consists of map information (91 to 99), and is stored in association with the location number of the part.

In addition, as shown in FIG. 3, the parts information section 2 also includes parts names, location numbers (storage locations), and
It stores the quantity, etc., and the storage location is updated each time parts are moved.

Next, the operational flow including the control unit 3.8 during cargo handling work will be explained separately for warehousing and warehousing.

FIG. 4 shows the operational flow during warehousing work.

In this case, the warehousing work instruction includes the part number to be stocked and the destination location number, for example, part number: 91.
43B-20000, Part name: FRONT AXL
E, quantity: 20, delivery address: 146, etc.

When a warehousing work instruction is first input from the input unit 4 in FIG. 1, the control unit 3 causes the modem 5 to transmit this work instruction to the cargo handling vehicle.

When the modem 6 on the cargo handling vehicle side receives this work instruction,
First, the control unit 8 issues a destination location number (for example, No.
146), the corresponding map information (for example, No.
0.1.14) is extracted from the map information section 7.

Thereafter, the control section 8 outputs the received work instruction and the extracted map information to the display section 10 for display.

Next, the operational flow during the unloading work will be explained based on FIG. 5.

First, when a warehousing work instruction (same format as the warehousing work instruction) is input from the input unit 4, the control unit 3 recognizes that it is a warehousing command, and first determines where the input part number is currently stored. Whether this is the case, the location number of the storage location is searched from the parts information section 2 to find out.

Next, the control unit 3 causes the modem 5 to transmit this work instruction and the extracted storage location number to the cargo handling vehicle.

When the modem 6 on the cargo handling vehicle side receives this information, the receiving section 8 extracts the corresponding map information from the map information section 7 based on the received storage location and destination location number. Thereafter, the control unit 8 causes the received work instruction, storage location number, and extracted map information to be held, and outputs them to the display unit 10 for display. Regarding map information, the storage location is displayed first. This is done by assigning a priority code to the storage location number.

When the worker reaches the storage location and inputs the unloading start key (delivery destination map information display command) from the input unit 9, the control unit 8 displays the map information of the delivery destination and accurately guides the cleaning worker to the destination. .

If a defect occurs in the working vehicle during such cargo handling work, the sensor group 11 first detects the defect and a defect signal is input to the control section 8, as shown in FIG. The control section 8 causes the screen display section 10 to display the defective state to inform the operator. As a display method, for example, a mark corresponding to a defective state as shown in FIG. Alternatively, a mark (shape) may be displayed on the screen display section 10, and the defect status mark corresponding to the defect signal input from the sensor group 11 may be lit or blinked.

Here, if the worker determines that the worker cannot perform the work due to the displayed defective state, he inputs a work-impossible signal from the input section 9 to the control section 8 . The control unit 8 transmits the input work disable signal to the control unit 3 via the modem 6.5. When a defective signal is input (distinguishing whether it is a defective signal or another signal is done by attaching a signal for identifying the signal type, etc.), the control section 3 sends an operation to the screen display section 1 based on the signal. Display that it is impossible (the display method is the same as above).

As mentioned above, if a work vehicle becomes unable to perform work, the central management department will be notified of this, allowing the central management department to issue work instructions to other workers. become.

Note that the working vehicle can be distinguished by marking the signal to be executed with an identification signal unique to the working vehicle.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

According to the present invention, since the central management section can recognize that a work vehicle has become unable to perform work, efficient work management can be performed by instructing another work vehicle to perform the work that cannot be performed. I can do it.
