DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cargo handling work recording apparatus for an industrial vehicle.

(Prior Art) Conventionally, Japanese Utility Model Laid-Open No. 57-138900 has been proposed as a device for recording the cargo handling work of industrial vehicles. This cargo handling recording device is capable of recording the load of a load during cargo handling work.

(Problems to be solved by the invention) However, since the cargo handling recording device as described above records only the data of the cargo handling work, it is not sufficient to know the movement status of the cargo, and for that purpose it is necessary to know the traveling distance. There is
In addition to the above cargo handling recording device, it is necessary to separately prepare a recording device for recording the traveling distance. However, if the load data and the traveling distance data are separately recorded by both recording devices, there is a problem that the accurate movement state of the load cannot be known.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a cargo handling work recording apparatus capable of recording traveling distance data and load data with one recording apparatus.

Configuration of the Invention (Means for Solving Problems) The present invention relates to load detecting means for detecting a load during a cargo handling operation, traveling distance detecting means for detecting a traveling distance of a vehicle, and detection signals from the both detecting means. Calculation means for performing calculation processing based on the above, storage means for storing the calculation processing result of the calculation means, a printer provided in the driver's seat, and reading the data relating to the load and the traveling distance stored in the storage means. And a cargo handling work recording device provided with a control unit for recording the traveling distance in the printer.

(Operation) The load detecting means detects the load during the cargo handling work, and the speed detecting means detects the traveling speed of the vehicle. The calculation means performs calculation processing based on the detection signals from both the detection means, and the storage means stores the calculation processing result of the calculation means. Then, the control means outputs the data relating to the load and the traveling distance stored in the storage means to the printer. Therefore, the printer prints the load and the traveling distance on the printing paper. As a result, the driver can immediately confirm the load and the traveling distance at that time from the printing paper.

(Embodiment) An embodiment in which the present invention is embodied in a cargo handling work recording device for a forklift will be described below with reference to FIGS. 1 to 3.

First, the electrical configuration of the cargo handling work recording apparatus will be described. The pressure sensor 1 as a load detecting means is provided in the lift cylinder 2. The pressure sensor 1 detects the hydraulic pressure of the lift cylinder 2 by utilizing the fact that the hydraulic pressure in the lift cylinder 2 is proportional to the load of the load W applied to the lift, and outputs a hydraulic pressure detection signal to the controller 5 described later.
Further, the electromagnetic pickup 3 as the traveling distance detecting means is arranged corresponding to the ring gear 4 provided in the differential gear mechanism that transmits the driving force from the driving source to the driving wheels of the forklift. The electromagnetic pickup 3 detects the number of teeth of the rotating ring gear 4 and outputs the number-of-teeth detection signal to the controller 5 described later.

The controller 5 includes an amplifier 6 that amplifies the hydraulic pressure detection signal to an appropriate magnitude, an A / D converter 7 that converts the amplified hydraulic pressure detection signal from an analog value to a digital value,
It is composed of a central processing unit (hereinafter referred to as a CPU) 8 as a calculation unit and a display control unit, an interface 9 and a clock integrated circuit (hereinafter referred to as a clock LSI) 10. The key input device 14 is provided on the operation panel of the driver's seat, and the key input device 14 is provided with a key for inputting the date and time and the like, and a recording switch.

The CPU 8 stores various control programs such as an arithmetic control program, a display control program, and a printer control program in a program memory 15 which is a read-only memory (ROM). Display 11 and printer
Controls and drives 12 output devices. Further, the CPU 8 is provided with a working memory 13 composed of a readable and writable memory (RAM) (not shown), and stores the calculation processing result at that time.

The display 11 for display is provided on the instrument panel of the driver's seat of the forklift and is capable of displaying a plurality of digits each consisting of a 7-segment LED. The printer 12 is provided in the driver's seat of the forklift.

Next, the operation of the cargo handling work recording apparatus configured as described above will be described with reference to FIGS. 2 and 3.

When the power is turned on and you start traveling or cargo handling,
The CPU 8 initializes the contents of the working memory 13 and various flags in step 1 (hereinafter step is represented by S). Next, the CPU 8 inputs the date and time data when a key is operated by the key input device 14 to input the date and time data, and stores the date and time data in a predetermined storage area of the working memory 13 (S
2).

Then, the CPU 8 reads the pulse number of the tooth number detection signal from the electromagnetic pickup 3 in S3. Then, in S4, the mileage is calculated based on the number of pulses, and the CPU 8 rewrites the contents of the mileage data storage area of the working memory 13 with the calculation result (mileage data). Next, the CPU 8 reads the hydraulic pressure detection signal in S5, calculates the load of the load loaded by the lift based on the read hydraulic pressure detection signal (S6), and stores the contents of the load data storage area in the working memory 13. Is rewritten to the calculation result (load data).

Subsequently, the CPU 8 executes the display output routine in S7 according to the flowchart of FIG.

That is, the CPU 8 reads the stored load data from the load data storage area of the working memory 13, outputs the load data to the display 11 for display via the interface 9, and displays the load data (S8). Then, the worker confirms, based on the data displayed on the display 11 for display, whether or not the load W is reliably lifted. Here, if the worker desires to keep a record, the worker turns on the recording switch 15.

Then, the CPU 8 reads the ON or OFF signal data of the recording switch stored in the work memory 13 in S9, and determines whether the recording switch is operated ON or OFF based on the data (S10).

If it is determined that the recording switch 15 is turned on,
The count number is added to the record count data stored in the record count storage area of the work memory 13, and the CPU 8 in S11, the load data stored in the load data storage area and the accumulation storage of the work memory 13 are stored. The integrated load data stored in the area is read and integrated. The integrated load data is data of an integrated processing result of the load data input at that time before the load data is input. Then, the new integration data that has been integrated in S11 is rewritten with the contents of the integration storage area.

Subsequently, the CPU 8 initializes various memories and mechanisms related to the printer 12 (S12), and sets various print data in S13 to S16. That is, the CPU 8 sets the recording count print data in the printing storage area based on the recording count data stored in the working storage area (S13). Further, the CPU 8 sets the date and time print data in the print storage area based on the date and time data stored in the predetermined storage area of the work memory 13 (S14).

Further, in S15, the CPU 8 sets the load print data and the calculated load print data in the print storage area based on the load data and the integrated load data stored in the load data storage area and the integrated load data recording area. Further, in S16, the CPU 8 sets the travel distance print data in the print storage area based on the travel data stored in the travel distance data storage area. When various print data are set in S13 to S16 as described above, the CPU 8 outputs the various print data via the interface 9 (S17) and controls the printer 12 for printing. When this print data is output, the control program returns to S2.
If the recording switch 15 is turned off in S10, S
Return to 2.

In this way, the cargo handling work recording device keeps a work record.

Note that the present invention is not limited to the above-described embodiment, and instead of a magnetic disk, a magnetic card, an IC card or the like as an output device, each data is output, and if a personal controller or the like is used, a long term or a plurality of units can be used. It will be possible to analyze the data for the vehicle.

Effects of the Invention As described above in detail, the present invention does not need to provide a separate recording device unlike the related art, and as a result, the manufacturing cost can be reduced and the load and the traveling distance can be recorded at the same time. Therefore, it is possible to grasp the movement of the load, and it is possible to perform detailed work management by performing multi-vehicle and long-term data analysis.
