Abstract

PURPOSE:To eliminate necessity for use of any cable connection between a host computer and a local computer by equipping each unmanned truck with a memory, connecting unmanned truck with a host computer and local computers of different processing devices through separable connectors, and thereby accomplishing transfer of information. CONSTITUTION:Each unmanned truck 1 is induced wirelessly on the basis of the transport information given from a host computer 14 to move to a processing device (either of 6 thru. 9) and is connected thereto by connectors 22, 28. The processing information from the host computer 14 is received by a wireless data receiver device 19 and fed to appropriate processing device. This eliminates requirement for arrangement of processing devices in the order of processing procedure and also necessity for connection of the host computer 14 with local computes (15...17) through cables.

It is provided separately.

[For production]

The automatic guided vehicle in this invention is wirelessly guided based on transport information from a host computer, moves to a target processing device, and connects to the target processing device via a detachable connector,
By giving the processing information transmitted from the host computer received by the wireless data receiving device to the processing device, multiple processing devices do not need to be arranged according to the processing procedure, and the host computer and local computer can be connected by cables. There's no need to.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows an automatic guided vehicle 1 applied to this embodiment, which includes a wireless guidance antenna 3, a wireless guidance device 12, a control device 18 having a storage device, and a wireless data receiving device 19.
, a wireless data receiving antenna 20, a plug driver unit 21, and a plug 22.

FIG. 2 shows the automatic addition system of this embodiment in which the same parts as in FIG.

FIG. 6 is a diagram showing the relationship between the host computer and the local computers provided in each processing device. The host computer 14 has a transmitting antenna 23 and a wireless data transmitting device 24 connected to the transmitting antenna. Further, the local computer is provided with a socket 28 corresponding to one lug 22 of the automatic guided vehicle 1.

This embodiment has the above configuration, and requires machining.
The work W is loaded onto the automatic guided vehicle 1 from the work warehouse 4. The automatic guided vehicle 1 and the host computer 14 are connected wirelessly by a wireless data communication device, and the automatic guided vehicle 1 receives processing information and transportation information transmitted from the wireless data transmitting device 24 of the host computer 14. The wireless data is received by the wireless data receiving device 19, directed to the target processing device, for example, the processing device 6 as shown by the solid line arrow 25, and the socket 28 of the local computer 15 and the plug 22 are connected by the function of the plug driver unit 21, and the wireless data is transmitted. The information received by the data receiving device 19 and stored in the storage device of the controller 18 is transmitted to the local computer 15, and the work is transferred to the processing device. The processing device 6 performs processing based on the transmitted information.

The plug connection continues until processing is completed. After receiving the processing completion information, the automatic guided vehicle 1 plugs the plug 22 from the socket 28.
