A parts information storage device is configured by having a wireless control circuit that allows communication, and a wireless communication device that wirelessly communicates with the wireless control circuit is configured by attaching a communication antenna to each manufacturing work site. It is characterized by comprising a management electronic computer that measures reading of component information from the device and writing of component information to the storage device, and has a man-hour management function based on the read component information.

(Function) In this configuration, the parts information storage means is attached to the pallet, and the communication between the parts information storage means and the management computer is performed in a wireless manner via the communication antenna and the communication device, thereby eliminating dust and the like. Malfunctions are reduced even under the presence of adverse influences. Furthermore.

Compared to the method of increasing the number of limit switches or proximity switches installed in each workplace, it is possible to save space and simplify the cable wiring route.

Therefore, when the operator inputs the start and end information on the management computer 3 at the time of starting and finishing the work, the storage circuit 1 of the parts information storage device 5 is controlled by the management computer 3.
The part number of the part stored in the pallet is read from 0, the part number is sent wirelessly to the communication antenna AT2, and further sent to the management computer 3 via the communication device 4, where it is stored and read out. The time when the work is started is recognized by the clock built into the management computer 3, and the work start time is determined.

It is stored in the management computer 3 as the end time.

Furthermore, when inputting the completion of work 2, the work time (actual results) for the parts at the workplace is recorded on the management computer 3, including the work start time and
Calculate and store based on the difference in end time.

The above process is carried out at the workplace 2 and thereafter, and the part number, work start time, end time, and work time information for each workplace are stored in the management electronic computer 3. Step 3 performs screen display and printout.

The man-hour management device 1 configured as described above communicates with the parts information storage device 5 and the management computer 3 by wireless method, so its function is not hindered even under adverse conditions such as 1 m of dust. ,tl!
