Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a handling system used in a mechanical processing system or the like.

(Prior Art) In a mechanical processing system, a handling system is used to take out a workpiece from an automatic guided vehicle and to place a processed workpiece onto the automatic guided vehicle.

In this case, the handling system includes, as shown in FIG. 3, a management computer 100 that manages the entire system, a handling control device 101 that generates handling control signals in response to handling instructions output from the management computer 100, and A handling device 102 that performs a handling operation based on a handling control signal output from a handling control device 101 is provided.

The handling control device 101 detects each time an automatic guided vehicle loaded with a transport pallet arrives at one of the transfer stations.

Based on this detection result, the handling control device 101 receives the relevant work instruction online from the management computer 100, controls the handling device 102 according to this work instruction, and takes out the workpiece from the automatic guided vehicle. , the processed workpiece is placed on an automatic guided vehicle.

(Problem to be Solved by the Invention) However, in the conventional handling system described above, the handling control device 101 controls the handling device 102 by receiving work instructions from the management computer 100. When the system malfunctions, there is a problem in that handling instructions must be manually entered offline.

Further, depending on the nature of the failure of the management computer 100, tracking information and the like must be corrected manually, which requires a great deal of effort during input work.

In view of the above circumstances, it is an object of the present invention to provide a handling system that allows a handling device to continue to be operated without manually inputting handling instructions even if the management computer fails.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, a handling system according to the present invention takes out a workpiece placed on a conveying pallet using a handling device and sets it in a processing machine, and the handling device In a handling system in which a workpiece is removed from the processing machine and loaded onto the transport pallet, the transport pallet side includes a storage section storing handling information, and a handling device that stores the handling information stored in the storage section. and a handling information capture unit that receives the handling information output from the output unit on the handling device side, and the handling device receives the handling information based on the handling information captured by the handling information capture unit. It is characterized by having the system perform handling processing.

(Function) In the above configuration, when the transport pallet reaches a predetermined location, the handling information stored in the storage unit on the transport pallet side is output from the output unit, and
The handling information outputted from the output section is captured by a handling information capture section attached to the handling device, and handling processing for the workpiece is performed based on this handling information.

(Embodiment) FIG. 1 is a block diagram showing an example of a production line to which an embodiment of the handling system according to the present invention is applied.

The production line shown in this figure includes a plurality of processing sections 18 to 1n that process workpieces, a transport route 2 arranged along these processing sections 1a to 1n, and a transport route 2 that runs on this transport route 2. The automatic guided vehicle 4 loads and unloads the pallets 3 for processing, and while the automatic guided vehicle 4 loads and unloads the pallets 3 for processing onto each of the processing sections 1a to 1n, Let object 5 be processed.

In this case, the conveyance pallet 3 includes a plate-shaped pallet body 6 and a display device 7 provided on the side of the pallet body 6.

As shown in FIG. 2, the display device 7 includes a handling information storage section 15 in which handling information is stored, and takes out the handling information stored in the handling information storage section 15 and converts it into a character code string and a graphic code string. and a display section 17 that displays the processing results of the processing section 16.
When the workpiece 5 is unloaded onto any one of the workpieces a to 1n, the display device 7 presents handling information to the processing section to instruct loading and unloading of the workpiece 5.

Each of the processing units 1a to 1n includes a station 8 that transfers the automatic guided vehicle 4 and the transport pallet 3, a processing unit 9 arranged at each station, and a space between each processing machine 9 and each station 8. Handling device 10 to be placed
and a reading device 11 attached to each handling device 10.

In this case, the reading device 11 includes a handling information reading section 18 that reads characters and figures displayed on the display section 17 of the display device 7, as shown in FIG. an information identification processing unit 19 that identifies characters and figures that have been detected and extracts handling information; and a loading/unloading pattern determining unit that creates a loading/unloading pattern for the workpiece 5 based on the handling information extracted by the information identification processing unit 19. It is equipped with 20.

Then, the transport pallet 3 was delivered to Station 8 of the own ship engineering department.
When the conveyance pallet 3 is loaded, the reading device 11 reads the characters and figures displayed on the display section 17 provided on the conveyance pallet 3, extracts handling information, and creates a loading/unloading pattern from this handling information. Then, it is supplied to the handling device 10 for handling processing.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2.

First, when the automatic guided vehicle 4 arrives at one of the processing units 18 to 1n, for example, the processing unit 1a, and unloads the transport pallet 3 to the station 8, the reading device 11 of the processing unit 1a
operates to read the characters and figures displayed on the display device 7 of the transport pallet 3 and extract hand and ring information, and also creates a loading/unloading pattern based on this handling information and sends it to the handling device 10. supply

As a result, the handling device 10 takes out the workpiece 5 from the transport pallet 3 based on this loading/unloading pattern, sets it on the processing machine 9, and then removes the processed workpiece 5 from the processing machine 9. Place it on the transportation pallet 3.

Then, when the workpiece 5 is placed on the conveyance pallet 3,
The automatic guided vehicle 4 receives the transport pallet 3 from the station 8 and starts traveling toward the next processing section.

Thereafter, the above-mentioned operation is repeated and each processed portion 1b to 1n is
The workpiece 5 is processed.

In this embodiment, the display device 7 is attached to the conveyance pallet 3, and the display section 17 of the display device 7 displays characters and figures indicating handling information, so that the handling information is displayed on the processing sections 18 to ln. is transmitted, so even if the management computer (not shown) breaks down, processing of the workpiece 5 can be continued without any problems.

Further, in the embodiment described above, the display section 1 of the display device 7
Although the handling information is transmitted to the reading device 11 by displaying characters and figures on the display 7, it is possible to use a bar code instead of the characters and figures. Instead of the information transmission method, an information transmission method using radio or the like may be used.

〔Effect of the invention〕

As described above, according to the present invention, even if the management computer fails, the handling device can continue to be operated without manually inputting handling instructions.
