Detailed description of the invention

Fig. 1 is the figure together represented the conveying robot device of an embodiment of the invention and the device of periphery.This is the conveying robot device such as heat-treating crystal liquid substrate.In the drawings, the conveying robot device transfer robot 1 that comprises both arms and the control device 2 that is made up of PLC (Programmable Logic Controller).Transfer robot 1 is connected by cable 3 with control device 2, and transfer robot 1 can perform and instruction and process accordingly, and this instruction is instructed to by the synchronous exchange between control device 2.

Particularly, first, transfer robot 1 is moved into from the workpiece (not shown) of loading unit 4 by crystal liquid substrate by both arms.Now, such as, the action of stretching, adsorbing of arm is carried out.Next, transfer robot 1 utilizes each arm of both arms by workpiece respectively to the first body of heater and the storage of the second body of heater.In addition, after releasing the workpiece of storage, take out completing other workpiece heat treated and return.Then, these are completed heat treated workpiece and be received into cooling end (or taking out of portion) 7, and carry to subsequent processing.

Fig. 2 is the flow chart of the action of transfer robot 1.After action starts, first transfer robot 1 carries out the initial treatment (step S1) of the regulation prepared for action.Then, transfer robot 1 carries out the judgement (step S2) that whether have received synchronous exchange from control device, and maintain the original state when not receiving wait-receiving mode unchangeably.In addition, the reception of synchronous exchange such as receives stroboscope (Strobe) signal of self-control device 2 by transfer robot 1 and sets up.After receiving synchronous exchange, transfer robot 1 entry instruction process (step S3), after this instruction process is complete, carries out returning origin position and the instruction termination (step S4) of stopping etc. completely.

Fig. 3 is the flow chart (subprogram) of the details of the instruction process (step S3) represented in Fig. 2.In figure 3, transfer robot 1 carries out instruction from control device 2 and reads in (step S31).Wherein, in detail, carrying out from control device 2 to after transfer robot 1 writes the action of instruction, control device 2 carries out the request of reading in transfer robot 1, thus the instruction carrying out transfer robot 1 is read in.Then, transfer robot 1 starts to perform the instruction (step S32) of reading in.Such as, if instruction is " moving into ", then transfer robot 1 starts to move into workpiece from loading unit 4 (Fig. 1).

Then, transfer robot 1 carries out the judgement of the continuous request of instruction, namely judges whether it is the pattern (step S33) performing multiple instruction continuously.Continuous request be controlled device 2 as presentation directives independent/continuous print mark and exporting, during carrying out continuous action, ask continuously to be output as continuous signal (such as H level is fixed).And when instruction is independent instruction, this mark is L level.When without (namely independent when) when requiring continuously, transfer robot 1 carries out the whether completed judgement of execution of instruction in step S34, if complete, return main program (Fig. 2), carry out instruction termination (step S4).

On the other hand, when there is request continuously in step S33, transfer robot 1 until during completing, carries out the report (representing the report can carrying out the reception of next instruction) (step S35) that can receive next instruction relative to control device 2 after from the execution of present instruction.When not being the opportunity of carrying out this report, perform present instruction, while wait for this opportunity.In addition, the completing of flesh and blood of said " completing " only presentation directives, does not comprise and returns origin position and situation about stopping completely herein.

Particularly, an instruction comprises multiple action, such as, carries out in order rotating to assigned address, rising, manipulator is extended, rise and receive absorption workpiece, make manipulator return this series of actions.At this, transfer robot 1 such as in the end starts with the action making manipulator return side by side to carry out receiving next instruction report.

Receive and above-mentioned can receive next instruction report, next instruction is write transfer robot 1 by control device 2, and the notice write by next instruction after write terminates is sent to transfer robot 1.At this, transfer robot 1 waits for that the notice that next instruction has write is sent (step S36) from control device 2, after confirmation write completes, returns step S31, is read in by the next instruction of write.After reading in, transfer robot 1 starts the execution (step S32) of next instruction.But, actual robot motion performs continuously with the last action of present instruction.Such as, if present executory instruction moves into, then next instruction receives in stove.

As described above, during wait instruction is complete, can next instruction be write, if write, read in.That is, the reservation of the instruction that next will perform can be carried out.Be read into " next instruction " to become " present instruction ", transfer robot 1 starts to perform (step S32).Then, transfer robot 1 until during completing, carries out receiving next instruction report (step S35) relative to control device 2 after execution starts.When being also less than the opportunity of carrying out this report, perform present instruction and etc. opportunity of pending this report.Then, transfer robot 1 starts side by side with the last action of present instruction, carries out receiving next instruction report (step S35).

Such as, if the instruction performed is the order of A instruction, B instruction, C instruction, then transfer robot 1 (specifically, starting side by side with last action) in A instruction performs receives the write of B instruction, reads in after having write.But, reading in of C instruction is not carried out.Then, the transfer robot 1 A instruction that continues directly performs B instruction.In addition, transfer robot 1 (specifically, starting side by side with last action) in B instruction performs receives the write of C instruction, reads in after having write.So, only next instruction can be preengage all the time, the multiple instruction of process continuously.All performed, no longer included the moment (being "No" in step S33) of request continuously in the multiple instruction of continuous print, transfer robot 1 is waited for complete (the step S34) of last instruction, after completing, return main program (Fig. 2), carry out instruction termination (step S4).

In above-mentioned such conveying robot device, the write of next instruction/read in (namely reading in advance) to perform such process is again carried out concurrently successively in the execution of present instruction, thereby, it is possible to perform multiple instruction continuously in synchronous exchange once.Therefore, with carry out the situation of synchronous exchange for each instruction compared with, the time needed for execution of whole carrying operation can be shortened.

Such as, with for from being moved to each instruction of receiving to cooling end 7 carry out compared with the situation of synchronous exchange, about 2 seconds can being shortened.

In addition, transfer robot 1 is only when have received information (the having the mark of request continuously) that represent the pattern performing multiple instruction continuously from control device 2, just carry out reading in of instruction, when not receiving this information, only perform present instruction and stop, thereby, it is possible to carry out the reliable judgement whether should reading in next instruction.In addition, useless action can not be carried out in discontinuous (independent) situation.

On the other hand, transfer robot 1 has crossover function.That is, even without returning origin position and stopping completely, also next instruction can be performed.According to this crossover function, do not complete due to an instruction and stop just can performing next instruction completely, thus the time needed for execution of whole carrying operation is shortened further.Such as, with from moving into until be received into carrying out synchronous exchange for each instruction and compared with the situation making it stop completely, about 6 seconds can being shortened of cooling end 7.That is, add the shortening realized by the reduction of synchronous exchange number of times, about 8 seconds can be shortened.Such as, in two stoves, when the productive temp of conveying robot device is 44 seconds, when treating capacity is 3928/1 day, shorten and become 36 seconds in 8 seconds, treating capacity becomes 4800/1 day, and production efficiency improves.

In addition, although eliminate explanation in the above-described embodiment, when performing the operation stopped very much, next instruction, except stopping the execution of present instruction immediately, is cancelled by transfer robot 1.Therefore, by stopping very much, positively can stop transfer robot 1 present with and subsequent action.
