In the present embodiment, if draw the distribution of this optimized installation exercise to each fitting machine 10, then be used to distribute the production routine of installation exercise, be stored in as initial production routine in the storage device on the control device 99 that is arranged at each fitting machine 10.In this production routine, not only have the installation elements kind of each installation exercise and the related data of the installation coordinate position on the substrate, also have the relevant information that the component supplying apparatus that will be used to carry out the feed element of installation exercise is installed to component supplying apparatus such as which position configuration of fitting machine 10.
When according to the distribution (initial production routine) of this optimized installation exercise when producing, determined each fitting machine 10 ... in the configuration of component supplying apparatus, and at each fitting machine 10 ... in the preparation work of last installation elements feedway, when a plurality of component supplying apparatus is installed, must make it be configured as the configuration of appointment.
But,, also can cause preparation mistakes such as mistaken installation site sometimes because therefore the exigent accuracy of this preparation work has strengthened operator's burden.
And, when carrying out actual preparation work, at each fitting machine 10 ... on the substrate of promising harsh output has been installed and the component supplying apparatus that is provided with, dismantle this device and realize the configuration of appointment.For example, be installed in the component supplying apparatus on the fitting machine 10, even in newly beginning the substrate of producing, use, if in new substrate, use the installation exercise of this component supplying apparatus to distribute to other fitting machines 10, even perhaps identical fitting machine, if specified different installation sites, also must temporary transient dismounting and moving meter feedway.
Therefore, in the present embodiment, corresponding to the configuration of current component supplying apparatus, the installation exercise (initial production routine) that change distributes in advance can improve the operability of preparation work thus.
And, based on the distribution (initial production routine) of optimized installation exercise, and change corresponding to current configuration, therefore can be easy to carry out the setting that the installation exercise corresponding to current configuration distributes.And, owing to kept the distribution of optimized installation exercise for the installation exercise that does not hinder current configuration, so can set the distribution of the installation exercise that can realize High-efficient Production.
Fig. 4 schematically shows the key diagram that installation exercise between each fitting machine moves example.Shown in Fig. 4 (a), among this routine fitting machine A, according to initial production routine, though require the component supplying apparatus that the feed element name is called the CCCCC element is installed being provided with on the F18 of position, and current identical the setting installed the component supplying apparatus that the feed element name is called the AAAAA element on the F18 of position.And, in fitting machine B, though require the component supplying apparatus that the feed element name is called the AAAAA element is installed being provided with on the F12 of position, and current identical the setting installed the component supplying apparatus that the feed element name is called the CCCCC element on the F12 of position.
At this moment, if distribute operation according to initial production routine, the component supplying apparatus of the feed element AAAAA that is installed on the fitting machine A is moved to the position F12 that is provided with of fitting machine B, the component supplying apparatus of the feed element CCCCC that is installed on the fitting machine B is moved to the position F18 that is provided with of fitting machine A.
In the case, installation exercise is moved, so that distribute to the installation exercise of each fitting machine by other fitting machines that the installation elements feedway that is used to carry out this installation exercise is installed.In the present embodiment, shown in Fig. 4 (b), make initial allocation move to fitting machine B for the installation exercise (and installation data) of the element CCCCC of fitting machine A, and make the installation exercise (and installation data) of the element AAAAA that distributes to fitting machine B move to fitting machine A.
That is, replace and move the preparation work of the component supplying apparatus of actual installation on each fitting machine, and the installation exercise of distributing to each fitting machine is moved by the operator.Reduce operator's preparation work thus and reduce the heavy burdens, and can produce the production of the substrate of object.
In this example, though between fitting machine A and fitting machine B respectively the installation exercise ground that distributes, clearing house move,, installation exercise also can only move towards the opposing party from a side.
Fig. 5 is the key diagram that schematically shows the information transmit-receive between each fitting machine.Shown in Fig. 5 (a), each fitting machine, be configuration and actual current configuration,, send (broadcasting) to other all fitting machines off and on as the ready message in this fitting machine (ready message of equipment itself) with the desired component supplying apparatus of production routine.And each fitting machine receives from the ready message (ready messages of other equipment) of other fitting machines of other fitting machines transmissions.The communicator that the control device 99 of each fitting machine is possessed is brought into play function as dispensing device, is used for sending the current configuration that is installed in the component supplying apparatus on each fitting machine to the outside.
Like this, obtained each fitting machine of the ready message in other fitting machines, contrasted the ready message of this fitting machine, suitable extraction preferably moves to the installation exercise of other any specific fitting machines from the installation exercise of distributing to this fitting machine.
Each fitting machine, if there is the best installation exercise that moves to other any specific fitting machines, then shown in Fig. 5 (b), to sending the preparation movement requirement that comprises the installation data that is used to carry out this installation exercise as other specific fitting machines of the moving target position of installation exercise.Receive other specific fitting machines of this signal, if can accept its requirement, then the fitting machine to the mobile original position of installation exercise sends information, and the fitting machine of mobile original position receives this requirement and accepts information, thereby can confirm that the installation exercise of distributing to this fitting machine can move.
So, in the present embodiment, the control device 99 of each fitting machine is interrelated, and corresponding to the current configuration of the component supplying apparatus of each fitting machine, will distribute to each fitting machine with respect to the installation exercise of each element of the substrate of producing object.Each control device 99 is then brought into play function as the installation exercise distributor.
Fig. 6 is the flow chart that shows the whole flow process of the substrate production in the installation assembly line.As shown in Figure 6, when producing the substrate of new kind, at first, prepare (step S1) as producing, in each fitting machine, access the employed production routine of substrate (step S2) of producing object, according to the conveyer belt width of each fitting machine of production routine automatic setting that accesses and (the step S3) such as height and positions of base plate supports plate.
Then, as preparation work, prepare to supply with the component supplying apparatus of the required electronic component of substrate of producing object and as (the step S4) such as electric substrates of mounting object, if be ready to complete by the operator, (step S6) produced in then entry into service (step S5).
In above-mentioned production process, supply with suitable electronic component and electric substrate (step S7), produced predetermined production quantity, then produce and finish (step S8), and turn back to the production preparation of next substrate.
Fig. 7 shows the flow chart that begins to produce the preparation work order of carrying out before.
This preparation work is to carry out in the step S4 of Fig. 6.Shown side by side among Fig. 7, among many fitting machines, will as initial production routine the installation exercise that distributes in advance entrust the installation exercise of other fitting machines to move original position and receive the processing of the installation exercise moving target position of this trust.
As shown in Figure 7, when carrying out preparation work, each fitting machine transmits the current configuration (current preparation) of the component supplying apparatus on this fitting machine (equipment itself) and installation exercise (production routine) information (step S10) of distributing to this fitting machine in advance of being installed in off and on mutually.
Under this state, each fitting machine judges that whether the preparation of moving the installation exercise of distributing to this fitting machine (equipment itself) in other fitting machines move necessity (step S12).For example, this judges, is in the installation exercise that has distributed, and whether estimate has the device that can not carry out with the current component supplying apparatus that is installed on this fitting machine etc. to carry out.If need not prepare to move (NO among the step S12), then this fitting machine can begin to produce, therefore, allow to begin on one side to produce (step S13), turn back on one side in the mutual transmission of current configuration etc., and make each fitting machine accept the preparation movement requirement of sending from other fitting machines (step S10).
Prepare to move (YES among the step S12) if necessary, just extract (step S14) and want the installation exercise that moves, and judge whether to exist other fitting machines (step S16) of the moving target position that can become the installation exercise that has extracted.Whether for example, this judges, be other fitting machines of wanting the required component supplying apparatus of installation exercise that moves are installed carry out to estimate to exist.
If there is no can become other fitting machines (NO among the step S16) of moving target position, then for the installation exercise of the substrate of producing object, be installed in current that the component supplying apparatus on each fitting machine is not enough to carry out this operation in the installation assembly line, therefore, by notifying output device such as this monitoring of information device to show preparation work indication picture (step S18), and turn back in the mutual transmission of current configuration etc. (step S10) to the operator.For example, when the component supplying apparatus that carries out certain installation exercise is not installed on this fitting machine, and in the time of also moving target position can't being become on other fitting machines, then demonstrate the preparation indication that the component supplying apparatus information of carrying out this installation exercise is installed less than installing.
If there are other fitting machines (YES among the step S16) that can become moving target position, then extract the installation data (step S20) of wanting installation exercise mobile in the fitting machine that can become moving target position, and in the fitting machine that can become moving target position, send (step S22) as preparing movement requirement.In this prepares movement requirement, comprise that simultaneously a plurality of installation exercises also are fine, and comprise lift-launch coordinate data on element title and the substrate etc. in the installation data of each installation exercise.
In fitting machine as the installation exercise moving target position, prepare movement requirement signal (step S24) if receive, then judge to receive this preparation movement requirement (step S26).For example, this judges, whether the component supplying apparatus that becomes object with evaluation element shortage etc. has taken place is carried out.At this moment, as the component supplying apparatus of object, if receive the preparation movement requirement, though with the reusable situation of other installation exercises under also be judged as and can accept.
If can not accept to prepare movement requirement (NO among the step S26), then in mobile original position, reply refusal and prepare mobile information (step S28), mobile original position is if receive this refusal result (step S30), the demonstration (step S18) of the information notice of then carrying out being not enough to carry out with the component supplying apparatus of being installed on current each fitting machine, and turn back in the mutual transmission of current configuration etc. (step S10).
In the moving target position of installation exercise, if can accept to prepare movement requirement (YES among the step S26), then reply (step S32) and accept the information of preparing movement requirement, and in mobile original position, append accepted installation exercise (step S38) to mobile original position.
On the other hand,, mobile original position accepts result (step S34) if receiving this, the installation exercise that will move then, and jump in mobile original position production routine (skip) handles (step S36).This is because mobile installation exercise if the configuration of desirable component supplying apparatus is in optimized state, is then preferably undertaken by this fitting machine, therefore need not eliminate from the production routine of this fitting machine, but handle with temporary transient jump.
For each fitting machine, need not prepare to move if be judged as like this, become the state (step S13) that begins to produce of allowing, then the whole erection streamline becomes the state that can produce.
As mentioned above, preparation work according to the management installation exercise, because corresponding to the current configuration that is installed in the component supplying apparatus on each fitting machine, move the installation exercise of distributing to each fitting machine in advance, again each fitting machine is carried out the distribution of installation exercise, therefore the operation of installation that the operator carries out, dismounting, moving meter feedway can be reduced, thereby preparation work can be easy to carry out.
And, if component supplying apparatus for deficiency, also be installed on any installation site of any fitting machine by the operator, then be reflected in the current configuration of its fitting machine component supplying apparatus, and carry out the distribution of installation exercise based on its configuration, therefore the preparation works such as installation exercise of not enough component supplying apparatus also become extremely simple.
And, the necessary component kind of installation exercise for the substrate of producing object, at least installing 1 on the fitting machine arbitrarily if supply with the component supplying apparatus of various elements, produce even also can begin under the situation about in a plurality of installation exercises, reusing, therefore, even the quantity of component supplying apparatus can not satisfy the optimal number of carrying out High-efficient Production, also can get started production, and can effectively utilize and satisfy the best component supplying apparatus quantity time before.
That is, when avoiding the reduction of production efficiency, by the simplification of component supplying apparatus preparation work, can improve its operability, the result can guarantee high productivity ratio.
The following describes the countermeasure when change takes place in the configuration of component supplying apparatus in the production operation.
Fig. 8 shows that the installation exercise that is carried out in the production operation process moves the flow chart of order when change takes place in the configuration of component supplying apparatus.Countermeasure during this is produced, be in the step S7 of Fig. 6, to carry out, identical with the flow chart of Fig. 7, shown side by side among Fig. 8 in many fitting machines, will according to initial production routine the installation exercise that distributes the in advance installation exercise of entrusting to other fitting machines move original position and receive processing on the installation exercise moving target position of this trust.
As shown in Figure 8, each fitting machine in process of production transmits the current configuration (current preparation) of the component supplying apparatus on this fitting machine (equipment itself) and the information of distributing to the installation exercise (production routine) of this fitting machine in advance of being installed in off and on mutually.
Under this state, each fitting machine judges that whether the preparation of moving the installation exercise of distributing to this fitting machine (equipment itself) to other fitting machines move necessity (step S52).
Be judged as and be necessary to prepare to move, the situation of distributing employed component supplying apparatus of installation exercise and generating device shortage etc. of having removed is for example arranged.Among the present invention, if the generating device shortage, then this component supplying apparatus become can't actual performance function state, therefore, be used as the situation that the configuration of removing component supplying apparatus takes place to change and handle.
And, when new component supplying apparatus being installed at this fitting machine or on other fitting machines, to use the whole or a part of of installation exercise to move on on the new component supplying apparatus with its component supplying apparatus provided as one homogeneous element, according to the load (workload) that whether alleviates this fitting machine, and then whether help the shortening of whole production pitch time, judge and prepare the necessity that moves.Preferably according to this fitting machine whether productive temp time of whole erection streamline is become bottleneck etc., corresponding size with other fitting machines this fitting machine load (workload) is relatively judged.
If need not prepare to move (NO among the step S52), think that then it is favourable that this fitting machine is continued to produce in the same old way, therefore, make it to receive the preparation movement requirement of sending from other fitting machines, and turn back to the mutual transmission step (step S50) of current configuration etc.
Prepare to move (YES among the step S52) if necessary, then extract and want the installation exercise (step S54) that moves, and judge whether (step S56) exists other fitting machines that can become the moving target position that has extracted installation exercise.This judgement, for example, be with estimate whether exist other fitting machines of wanting the required component supplying apparatus of installation exercise that moves are installed, the size of other fitting machines loads is compared as how carrying out with this fitting machine.
If there is no can become other fitting machines (NO among the step S56) of moving target position, then to notify output devices such as this monitoring of information device to show preparation work indication picture (step S58) to the operator, and judge that (step S59) do not exist a component supplying apparatus of supplying with required kind of class component etc., the state that can not continue to produce.If can not continue to produce (NO among the step S59), then breaks in production (step S92).If can continue to produce (YES among the step S59), then turn back to the mutual transmission step (step S50) of current configuration etc.
If there are other fitting machines (YES among the step S56) that can become moving target position, then extract the installation data (step S60) want the installation exercise that moves to the fitting machine that can become its moving target position, and send (step S62) to the fitting machine that can become moving target position as preparing movement requirement.This prepares can to comprise a plurality of installation exercises simultaneously in movement requirement, and in the installation data of each installation exercise, comprises lift-launch coordinate data on element title and the substrate etc.
And, when installation exercise moves original position and is in the upstream side of moving target position, this is prepared in the movement requirement, comprise the information of determining substrate, this substrate (below, this substrate is called preparation moves the back workpiece) be to produce by preparing to move under the state that changes the fitting machine that carries out installation exercise.And, in the fitting machine of mobile original position, there is the substrate be in the production process, when moving not the installation exercise that substrate is carried out, also comprise the information of this substrate of determining to be in the production process (below, this substrate is called dividing processing object workpiece).Determine the information of these substrates, the series management numbering of substrate and Lot Number etc. are for example arranged.Comprise that the information of determining this substrate is in order to determine that with the device of upstream side the preparation of producing moves back workpiece and dispersion treatment object workpiece under the state of mobile installation exercise.
In fitting machine one side that becomes the installation exercise moving target position, receive when preparing movement requirement (step S64), judge that then can (step S66) accept this preparation movement requirement.
This judgement, for example, be with evaluation become the element surplus of component supplying apparatus of object whether sufficient, in this moving target position fitting machine, whether have component supplying apparatus in the running of handover preparation element, when the moving target position fitting machine is in the upstream side of mobile original position fitting machine, whether reach the production predetermined number that becomes the substrate of preparing mobile object, and the production etc. that has begun the substrate of next kind is carried out.
If can not accept to prepare movement requirement (NO among the step S66), then reply refusal and prepare mobile information (step S68) to mobile original position, if mobile original position has been accepted this refusal result (step S70), after this information of display notification (step S58), judge whether to continuing the state (step S59) of production, if can not continue to produce (NO among the step S59), then breaks in production (step S92).If can continue to produce (YES among the step S59), then turn back to the mutual transmission step (step S50) of current configuration etc.
On the moving target position of installation exercise,, then reply the information (step S72) of preparing movement requirement of accepting to mobile original position if can accept to prepare movement requirement (YES among the step S66).When the installation exercise moving target position is in the upstream side of mobile original position, replys and accept in the information of preparing movement requirement, comprise the information of determining to prepare to move back workpiece or dispersion treatment object workpiece.Comprise that this information is in order to determine that with the device of upstream side the preparation of producing moves back workpiece and dispersion treatment object workpiece etc. under the state of mobile installation exercise.
Mobile original position fitting machine is received this and is accepted result (step S74), judge in mobile original position fitting machine that then becoming the substrate of producing object is to prepare to move the back workpiece, or dispersion treatment object workpiece (step S76, S80), if wherein which neither (NO among step S76, the S80), then continue to produce with the production routine before preparing to move.
If prepare to move back workpiece (YES among the step S76), then carry out the jump of mobile installation exercise and handle (step S78).Afterwards, the production routine after then moving with the preparation of mobile installation exercise is produced.
If dispersion treatment object workpiece (YES among the step S80) then carries out dispersion treatment (step S82) to this workpiece.Dispersion treatment, be meant under executing state not downstream the side fitting machine send the workpiece (dispersion treatment object workpiece) of in the upstream side fitting machine, preparing a part of installation exercise before changing, in the fitting machine of downstream, replenish the processing of finishing this unenforced installation exercise.Owing to after the dispersion treatment object workpiece, send into and prepare to move the back workpiece, therefore, to the installation exercise that moves the processing (step S78) of jumping.Afterwards, the production routine after then moving with the preparation of mobile installation exercise is produced.
On the other hand, accept the installation exercise moving target position fitting machine of preparing movement requirement and judge that similarly becoming the substrate of producing object in the moving target position fitting machine is to move back workpiece or dispersion treatment object workpiece (step S84, S88), if wherein which neither (all being NO among step S84, the S88), then continue to produce with the production routine before preparing to move.
If prepare to move back workpiece (YES among the step S84), the processing (step S86) of then carrying out in production routine, appending the installation exercise of being accepted.Afterwards, the production routine after then moving with the preparation of mobile installation exercise is produced.
If dispersion treatment object workpiece (YES among the step S88) then carries out dispersion treatment (step S90) to this workpiece, carry out in production routine, appending the processing (step S86) of the installation exercise of being accepted then.Afterwards, the production routine after then moving with the preparation of mobile installation exercise is produced.
Fig. 9 is presented at the key diagram that the installation exercise that is carried out when generating device is short in the production operation process moves example.Shown in Fig. 9 (a), in usual production, the component supplying apparatus of feed element A, B, C is installed on upstream side fitting machine A, and is distributed the installation exercise that carries these elements.And, the component supplying apparatus of feed element D, E is installed on the fitting machine B of downstream, and is distributed the installation exercise that carries these elements.
Here, be example with element A, on each substrate, carry a plurality of element A, a plurality of installation exercises that will carry a plurality of element A on substrate are respectively distributed to fitting machine A.Therefore, in the substrate of producing in usual production the (1), all element A carry with fitting machine A.
Shown in Fig. 9 (b), if the element A generating device shortage in fitting machine A, the installation exercise that fitting machine A itself is distributed just can not carry out, and therefore becomes the state of searching other fitting machines that can become moving target position.
At this moment, wait the component supplying apparatus of installing to the fitting machine B in fitting machine A downstream feed element A by the operator, correspondingly change the configuration of this component supplying apparatus, requirement is moved to the preparation of fitting machine B from fitting machine A, fitting machine B accepts this requirement, and then all installation exercises to element A move to fitting machine B from fitting machine A.
But, generating device when shortage, in fitting machine A, be in the substrate (2) in the production process, under the state of a part of installation exercise of executive component A not, promptly stop to produce.But, in this example, owing to move among the fitting machine B that the installation exercise of fitting machine A is surveyed downstream, therefore, fitting machine A is the information of dispersion treatment object workpiece to fitting machine B transferring substrates (2), and take out of substrate (2), and replenish with fitting machine B and to finish the unenforced installation exercise of fitting machine A.Shown in Fig. 9 (c), become in the substrate (2) of dispersion treatment object workpiece, the part of element A is to carry with fitting machine A, remainder is to carry with fitting machine B.
Like this, move installation exercise to element A to fitting machine B, begin once again thus to produce, shown in Fig. 9 (d), installation exercise moves in the substrate of making the back (3), and all element A carry with fitting machine B.
Figure 10 is the key diagram that the installation exercise that carried out when appending component supplying apparatus in production operation moves example.Shown in Figure 10 (a), in usual production, the component supplying apparatus of feed element A, B, C is installed on upstream side fitting machine A, and is distributed the installation exercise that carries these elements.And, the component supplying apparatus of feed element D, E is installed on the fitting machine B of downstream, and is distributed the installation exercise that carries these elements.
Here, with element A is example, on each substrate, be equipped with a plurality of element A, and, in initial arrangements of components (configuration of component supplying apparatus), distribute a plurality of installation exercises that carry a plurality of element A respectively to fitting machine A, in the substrate (1) of initial production, all element A carry with fitting machine A.
Shown in Figure 10 (b), suppose to wait the situation that the component supplying apparatus of feed element A is installed in fitting machine B by the operator.At this moment, the preparation element of well known elements A is installed to the fitting machine A on the fitting machine B, a part of installation exercise of the element A that in fitting machine B moves this fitting machine A, is distributed, and suitably share a plurality of installation exercises to element A according to the load balancing of fitting machine A and fitting machine B, and to be judged as from the viewpoint of the production efficiency that improves the whole production streamline be favourable.
At this moment, require to move to the preparation of fitting machine B,, the part of the installation exercise of element A is then moved to fitting machine B from fitting machine A if fitting machine B accepts this requirement from fitting machine A.
So, shown in Figure 10 (c), prepare when mobile in the substrate (2) that fitting machine A moves into, though all element A carry in fitting machine A, but shown in Figure 10 (d), move into becoming among the fitting machine A after preparing to move and prepare to move in the substrate (3) of back workpiece, the part of element A is to carry with fitting machine A, and remainder is to carry with fitting machine B.
As mentioned above, in the present embodiment, because the distribution that can change installation exercise corresponding to the configuration change of the component supplying apparatus that is taken place in the production operation process, therefore, can be flexibly corresponding to the configuration change of the component supplying apparatus that is taken place in the production operation process, and carry out High-efficient Production.
Particularly, in the production operation process, flexibly corresponding to the situation of generating device shortage in the component supplying apparatus arbitrarily, and when on other fitting machines, the component supplying apparatus of supplying with provided as one homogeneous element being installed, change is to the distribution of the installation exercise of this element, thereby can continue to produce.
And, even generating device shortage on any one component supplying apparatus and when temporarily stopping to produce, as long as the component supplying apparatus of supplying with provided as one homogeneous element is installed on the fitting machine of generating device shortage or its downstream fitting machine, then move its installation exercise in the side fitting machine downstream, transmit the residual substrate of not carrying out installation exercise in the fitting machine of generating device shortage thus downstream in the side fitting machine, finish remaining installation exercise thereby can replenish.
And, supply with the component supplying apparatus that carries the many elements of quantity, append when being installed on any one fitting machine, thereby mobile installation exercise will carry the installation exercise of this element keeps distributing to many fitting machines well balancedly, generation can be suppressed to thus, and the production efficiency of whole erection streamline can be improved into the fitting machine of production pitch time bottleneck.
More than, the 1st execution mode involved in the present invention has been described, but present embodiment is not limited only to said structure, as described below, can suitably change.
In the above-mentioned execution mode, though corresponding to current component supplying apparatus, change the distribution (initial production program) of best installation exercise,, need not on each fitting machine, distribute installation exercise in advance, can distribute corresponding to the configuration of the current component supplying apparatus in each fitting machine.At this moment, the setting that installation exercise distributes, when communicating between each fitting machine, the host computer of available unified management installation assembly line carries out, and also available any apparatus (fitting machine) is carried out.
And, configuration corresponding to the component supplying apparatus of each fitting machine, move when distributing to the installation exercise of each fitting machine in advance, not the installation data of mobile storage in the storage device of each fitting machine, but in the host computer of unified management installation assembly line, the installation exercise of distributing to each fitting machine is changed distribution as the installation exercise to other each fitting machines, and only send based on the production routine of the installation exercise of finally distributing to each fitting machine as the change result, and be stored in the storage device of each fitting machine to each fitting machine.
The 2nd execution mode
Secondly, the 2nd execution mode involved in the present invention is described.Be applicable to the fitting machine that installation assembly line, this installation assembly line comprised of the 2nd execution mode and the basic structures such as function of fitting machine component feeding portion, (therefore Fig. 1～Fig. 3) identical, omits explanation with the 1st execution mode.Only difference is elaborated below.
In the installation assembly line 90 of the 2nd execution mode, will distribute to the component supplying apparatus on any fitting machine that is installed in installation assembly line 90 to the installation exercise of the various elements of the substrate of producing object.Then, for the element on any fitting machine that is not installed to installation assembly line 90 in the required element, notification operator also impels it to install on any fitting machine of installation assembly line 90.
According to this method of operation, if supply with on any fitting machine that the component supplying apparatus of required element is installed in streamline 90, then can reduce the installation undertaken by the operator, dismounting, mobile operation, therefore can be easy to carry out preparation work this component supplying apparatus.For example, during actual preparation work, the employed component supplying apparatus of substrate of harsh product has been installed on each fitting machine, has therefore been utilized this point can obtain good operability.
But, if corresponding to the current component supplying apparatus that is installed on each fitting machine, distribute installation exercise to each fitting machine, then, may cause distributing on each fitting machine the imbalance of installation exercise load according to the kind combination of kind that is installed in the component supplying apparatus on each fitting machine and the substrate of producing object.It is medium that particularly installation exercise concentrates on specific fitting machine, and other install captain's the equipment that becomes the neck bottle to produce the installation exercise time ratio, then may cause the reduction of whole erection streamline integral production efficient.And, for each fitting machine, according to the combination of the configuration of institute's installation elements feedway and the installation exercise that distributes on its fitting machine, the distance of head is elongated in each installation exercise, perhaps by head simultaneously the chance of absorptive element tail off etc., can not obtain high production efficiency.
At this, in the present embodiment, in the configuration of current component supplying apparatus, required supposition production time when substrate production is carried out in calculating, and judge that whether its time satisfy the permission production efficiency benchmark of regulation, can judge thus whether the configuration with current component supplying apparatus is fit to carry out substrate production.
In the present embodiment, inferring the production time, is to be object with the installation assembly line that possesses many fitting machines, therefore, adopts supposition C cycle time of performance whole erection streamline substrate production efficient.That is, send the time interval that substrate is finished in the production in the whole erection streamline.Particularly, among the supposition production time of each fitting machine, needing the supposition production time of the fitting machine of long production time is the supposition production time of whole erection streamline.
The supposition production time of each fitting machine, be that the installation exercise of distributing to each fitting machine with the configuration of current component supplying apparatus is a condition, obtain the concrete execution sequence of production operation according to optimization method, and on optimized execution sequence, calculate the supposition production time as required time.Comprise in this execution sequence, when having the component supplying apparatus of a plurality of supply provided as one homogeneous element, use which component supplying apparatus, use which head, can adsorb simultaneously, the affirmation of absorptive element and check in use the setting etc. of which video camera, each installation exercise order.And optimization method is to adopt any one disclosed method.
And, when the production predetermined number after a little while, drop into the time of installation assembly line till finish in order to reflect from substrate, also can use the summation of the supposition production time of each fitting machine.
On the other hand, allow the production efficiency benchmark, it is the benchmark of judging above-mentioned supposition production time quality, in the present embodiment, the component supplying apparatus that has distributed each fitting machine for this installation assembly line ideally, and set based in each fitting machine, being configured in production time under the state on the desirable installation site (below, comprise that the distribution to each fitting machine is called desired configuration) (below, be called the desirable production time).
The desirable production time of component supplying apparatus, be based on optimization method calculate to the distribution of the installation exercise of each fitting machine set, to the distribution of the component supplying apparatus of each fitting machine, configuration, the concrete execution sequence of production operation to the component supplying apparatus of each each installation site of fitting machine, and from optimized execution sequence, calculate the above-mentioned desirable production time.The desired configuration of component supplying apparatus can be used as the configuration that obtains the component supplying apparatus of ideal during the production time and obtains.And optimization method can adopt any disclosed method.In the present embodiment,, be object also, therefore adopt ideal period time C ' with the installation assembly line that possesses many fitting machines for this ideal production time.
And, in the present embodiment, in order to judge more accurately whether begin production with current configuration is fit to, permission production efficiency benchmark was added in the above-mentioned desirable production time, and with reference to moving (preparing to replace) the required supposition time d of component supplying apparatus and set to above-mentioned desired configuration from current configuration.
For example, in the present embodiment, be to obtain the component supplying apparatus quantity that is necessary to dismantle, the component supplying apparatus quantity that is necessary to reinstall, the component supplying apparatus quantity that a fitting machine, is necessary to move, be necessary the component supplying apparatus quantity that moves to other fitting machines, and obtain based on the product of the standard operation time of setting corresponding to each operation type and to infer time d from the configuration of current component supplying apparatus and the difference between the desired configuration.
And in the present embodiment, for can be with dimension ground relatively to the supposition time and the production time (cycle time) of each substrate that desired configuration moves, permission production efficiency benchmark be set with reference to the production predetermined number n of the substrate of this production object.
Particularly, obtain above-mentioned desirable production time (ideal period time) C ' of each substrate and the product of production predetermined number n, obtain thus from production and begin to the net production time of producing till finishing, and wherein add and prepare to replace required above-mentioned supposition time d, can obtain thus from current configuration and move and produce required prediction total ascent time the C ' * n+d of substrate that finishes the production predetermined number to desired configuration.
On the other hand, as the product of above-mentioned supposition production time of each substrate in the current configuration (inferring cycle time) C and production predetermined number n, can obtain to begin to produce and finish required prediction total ascent time C * n till the production with current configuration.
By two prediction total ascent times obtaining more like this, quantitative comparison just can be judged the production efficiency in the current configuration more accurately with current the configuration situation that begins to produce and the condition of production of carrying out after the preparation work of desired configuration.
Then, as final judgment standard, the difference that is based on both the predefined permission time difference with interior (for example, in 30 minutes) situation, ratio between two predefined permissible ratio with the situation of interior (for example, 10% in), satisfy both sides or satisfy a side etc. at least and judge.
This final judgment standard, can be when preparing to replace necessary operator's labour costs, prepare wrong incidence and wait suitably and set.
The result of this final judgment standard if the configuration that is judged as with the present situation component supplying apparatus is fit to begin produce, then gives each fitting machine production permit, and becomes the state that can begin to produce.
On the other hand, if the configuration that is judged as with the present situation component supplying apparatus is not suitable for beginning producing, then this information is notified to the operator.Thus, can prevent to begin to produce and the production schedule surpasses measurable level and causes the state of fault with the low production efficiency below the stipulated standard in advance.
And, when under the configuration of current component supplying apparatus, being not suitable for producing, then make the configuration change scheme of the component supplying apparatus that can enhance productivity, and be notified to the operator as preparing to replace indication.This prepares to replace the content of indication, may not be to be the indication of desired configuration with current configuration change.
As based on this configuration change content of preparing to replace indication, for example have in each fitting machine, to make several component supplying apparatus be adjacent to move, so that increase the chance of absorptive element simultaneously; Perhaps make component supplying apparatus to moving near the position of the installation site on the substrate etc.
And, the viewpoint of enhancing productivity from installation assembly line, for example judge the load balancing of each fitting machine, the installation exercise that maybe will occur being distributed in the fitting machine of peak load moves in the little fitting machine of load, makes the preparation of moving between the used component supplying apparatus fitting machine of this installation exercise replace operation thereby can set.
Like this based on the configuration of preparing to replace indication change component supplying apparatus, then in the fitting machine of preparing to replace, for each installation exercise that distributes, can change installation elements kind, use the installation site of component supplying apparatus, in data such as the installation coordinate position of substrate with comprise the production routine of the sequential scheduling that carries out each installation exercise.
In the present embodiment, more than infer making of the calculating of production time, the judgement of whether satisfying permission production efficiency benchmark and configuration change scheme etc., be to constitute, and undertaken by the supervisory computer of each fitting machine operation of unified management installation assembly line 90 by the control device 99 of each fitting machine of this installation assembly line 90 and the personal computer that can utilize telecommunication cable to receive and send messages.
Figure 11 is illustrated schematically in the key diagram of receiving and sending messages between each fitting machine.As shown in figure 11, each fitting machine and supervisory computer (PC) connect with network, and can receive and send messages.
Each fitting machine is the current configuration of component supplying apparatus that fitting machine itself is installed and the installation exercise that is distributed, as the ready message of equipment itself, and transmission in the supervisory computer (PC) of the network unified management preparation work of installation assembly line.The communicator that the control device 99 of each fitting machine is possessed is to bring into play function with dispensing device.Wherein dispensing device sends the current configuration that is installed in the component supplying apparatus on each fitting machine to the outside.
Receive the supervisory computer (PC) of ready message from each fitting machine, calculate based on the ready message of each fitting machine and infer the production time, and whether satisfy permission production efficiency benchmark according to its time and judge with current configuration whether be fit to begin produce.This supervisory computer is as calculation element that calculate to infer the production time, and judges whether to satisfy and allow the judgment means of production efficiency benchmark to bring into play function.
The above-mentioned judged result that begins to produce of whether being fit to, if being fit to begin produces, then supervisory computer allows each fitting machine of installation assembly line to begin to produce.
On the other hand, if being not suitable for beginning produces, then its information is notified to the operator, and supervisory computer is emitted in the idsplay order that display unit 98 (monitor picture) goes up its information of demonstration to each fitting machine.And supervisory computer is made the configuration change scheme of the component supplying apparatus that improves production efficiency, and to the fitting machine as the configuration change object, is emitted in the idsplay order of configurations shown change indication (preparing to replace indication) on the display unit 98.The display unit 98 of each fitting machine is brought into play function as notifying device.
And supervisory computer carries out optimization and makes production routine in each fitting machine under the state of change component supplying apparatus configuration, and its information is sent to each fitting machine.Each fitting machine receives in the storage device that is stored in after this information separately, thus, can produce with the state after preparing to replace.
Figure 12 is the flow chart that shows the preparation work order in the installation assembly line.This preparation work is to carry out in the step S4 of Fig. 6.And the whole flow process of the substrate production in the installation assembly line of the 2nd execution mode is basic identical with Fig. 6 flow chart that has illustrated, therefore omits its explanation.
As mentioned above, in the present embodiment, at first,, on each fitting machine, distribute installation exercise, and the component supplying apparatus of supplying with short element is installed corresponding to the configuration of component supplying apparatus.
As shown in figure 12, in each fitting machine, if finish the installation of being undertaken by the operator that should prepare electronic component (preparation) (step S100), then supervisory computer is collected the configuration of current component supplying apparatus in each fitting machine, is distributed used component information of installation exercise and production routine key elements (step S102) such as assembling coordinate etc.
Then, supervisory computer is according to the component supplying apparatus of installing on each fitting machine, comprise and judge the preparation inspection (step S104) that has or not short element, if preparation inspection is false (NO among the step S104), then each fitting machine is sent and indicate the preparations such as component supplying apparatus installation of supplying with short element to revise indication (step S106).Each fitting machine notification operator is prepared to revise indication and is impelled the operator to prepare to revise.
If prepare to check establishment (YES among the step S104), then owing to can produce with the current component supplying apparatus that in each fitting machine of installation assembly line, disposes, so in each fitting machine under the configuration of current component supplying apparatus, obtain the concrete execution sequence (step S108) of production operation with optimization method, and calculate the supposition production time (step S110) of current configuration.
Next obtains the permission production efficiency benchmark to the substrate of producing object.At this moment, judge whether the prediction production time data under the perfect condition of desired configuration component supplying apparatus calculate (step S112).If calculate (YES among the step S112), just in perfect condition, access the desirable production time (step S114) of prior prediction.Produce desirable production time in the installation assembly line of substrate of object for each, do not entrust configuration, and, just can not change as long as the structure of fitting machine is certain in current component supplying apparatus.
If the prediction production time data of not calculating in advance (NO among the step S112), the production routine optimization of then carrying out under the perfect condition is calculated (step S116), and calculates the production time (desirable production time) (step S118) under the perfect condition.And, in this optimization is calculated, need not the configuration of retaining element feedway, and obtain desired configuration and calculate production time under the desired configuration.
If draw the desirable production time, just moving meter feedway from the configuration of current component supplying apparatus is calculated time required when realizing this perfect condition (desired configuration) (inferring time) (step S120).
Possessed supposition production time in the current configuration, the desirable production time in the desired configuration like this and moved on to desired configuration required supposition time, just can judge and infer whether the production time satisfy based on the desirable production time and infer time and the permission production efficiency benchmark (step S122) set from current configuration.
This judged result if satisfy benchmark (YES among the step S122), then begins to produce also with current configuration and can guarantee certain production efficiency, therefore can allow to produce (step S124).
Whether on the other hand, this judged result if do not satisfy benchmark (NO among the step S122), exception reporting (step S126) just occurs, and begin to produce with the current configuration that may influence production efficiency to the operator inquiry.These exception reportings etc. are based on the idsplay order from supervisory computer, carry out in each fitting machine, and are presented on the monitor of each fitting machine, are notified to the operator with this.
Figure 13 is the exception reporting picture example when production efficiency can not satisfy benchmark in the current configuration.As shown in figure 13, when production efficiency did not satisfy benchmark, notice did not satisfy the degree of its benchmark yet.Particularly, show move on to 25 minutes and 00 second required when producing the individual substrate of 50 (production predetermined number) after the perfect condition anticipation production time, with present situation configuration (current standby condition) required 40 minutes and 24 seconds anticipation production time and perfect condition moved ratio 162% in the current standby condition that is made as at 100% o'clock when beginning to produce.
And, in this exception reporting,, can select to begin by force to produce with current configuration according to operator's judgement.
For the selection branch (step S128) that whether begins to force to produce, begin to force the information (YES among the step S128) of producing if imported by the operator, although influence production efficiency, but got all the ready and produced required element and can produce, therefore can allow to produce (step S124).
On the other hand, do not force the information (NO among the step S128) of producing, then send preparation correction indication (step S106) for enhancing productivity to the operator if imported.This prepares to revise indication, according to the idsplay order from supervisory computer, carries out in each fitting machine, and is presented in the monitor of each fitting machine, is notified to the operator with this.At this moment, in each fitting machine, send the production routine of preparing to revise under the state of back (finishing optimized production routine) together.
Figure 14 is a picture example of preparing to revise indication.For example, Figure 14 (a) sends fitting machine A, and is presented on the display unit (monitor) 98 of fitting machine A.Figure 14 (b) sends fitting machine B, and is presented on the display unit (monitor) 98 of fitting machine B.Particularly, in the fitting machine A of Figure 14 (a), in all four the component feeding portions of this fitting machine except that the lower right its standby condition be OK, the mark part that shows bottom-right component supplying apparatus and installation site F21 then sends ruddiness, and, as " dismounting element: the PARTS013 (F21) " that show in the operation indication hurdle, send the field-strip indication of the component supplying apparatus (belt feeder of 8mm band) of the feed element PARTS013 element by name that is installed on the F21 of this installation site.
And, among the fitting machine B of Figure 14 (b), in all four the component feeding portions of this fitting machine except that the lower right its standby condition be OK, show that the component supplying apparatus of bottom right and the mark of installation site F21 then send red light, and, as " element is installed: PARTS013 → F25 " that show in the operation indication hurdle, send the installation exercise indication of the component supplying apparatus (belt feeder of 8mm band) of the feed element PARTS013 element by name that is installed on the F21 of this installation site.
Indication is revised in these each preparations, is to be undertaken by the display unit of the fitting machine that carries out this operation itself, so the operator can be easy to grasp the content of preparing to replace operation.
Prepare as described above to replace, turn back to step S100, and the production efficiency of the configuration in the component supplying apparatus after the evaluation preparation replacement, produce if can guarantee certain production efficiency then begin.
More than, be illustrated for the 2nd execution mode, but present embodiment is not limited only to said structure, as described below, can carry out suitable change.
In the present embodiment, the supervisory computer of unified control each equipment of installation assembly line (fitting machine), though bring into play function with the calculation element of inferring the production time, the judgment means that whether satisfies permission production efficiency benchmark, also can make the control device of any fitting machine bring into play function.
And, also can make each equipment (fitting machine) that constitutes installation assembly line calculate and judge whether to satisfy permission production efficiency benchmark about supposition production time of equipment itself.
And, in the above-mentioned execution mode, be object though will possess the installation assembly line of many fitting machines (equipment), also can be used on the single fitting machine.At this moment, the control device that the computer that fitting machine possessed etc. constitute can be used as the aforementioned calculation device, judgment means is brought into play function.
And, in the above-mentioned execution mode, desirable production time C ' and supposition production time C, be meant from moving into substrate and the time of taking out of after the related various operations till the substrate being installed, but, carry out simultaneously for the downstream fitting machine move into the upstream side fitting machine in take out of the time, this time can be the time till moving into substrate and related various operations being installed.
And, in the above-mentioned execution mode, produce to desired configuration moves after from current anticipation configuration and to finish the required anticipation total ascent time of production predetermined number substrate, employing C ' * n+d obtains, still, move into new substrate, and when taking out of last substrate, not necessarily many fitting machine portions carry out installation exercise, therefore, at this moment, can adopt C ' * (d+ fitting machine number-1)+d as the anticipation total ascent time.And, carry out simultaneously moving into when taking out of with the substrate of upstream side fitting machine for the substrate of downstream fitting machine, as the anticipation total ascent time, can adopt C ' * (n+ fitting machine number-1)+d+ to move into the time.
Equally, about inferring the anticipation total ascent time of production time C, replaced C * n and adopt C * (n+ fitting machine number-1), and, carry out simultaneously the downstream fitting machine move into the taking out of of upstream side fitting machine the time, as the identical anticipation total ascent time, can adopt C ' * (n+ fitting machine number-1)+d+ to move into the time respectively.
And, as the set-up time, only with reference to many parts that fitting machine is related, but, installation assembly line also has substrate except many fitting machines moves into machine 91, printing machine 92, inspection machine 93, reflow stove 94 and substrate and takes out of other various devices such as machine 95, and exists in each equipment substrate to accept and fulfil assignment the required production time.The production time of these each equipment makes the production time (cycle time) of each equipment consistent with the longest production time, and its buffer that needn't dispose storage substrate also can be finished when inconsistent.The production time (cycle time) of the equipment side beyond this fitting machine and installation pusher side production time, (cycle time) was inconsistent the time, make two production times (cycle time) consistent.Promptly, make the production time (cycle time) that pusher side is installed carry out preparation support the shortlyest, and production time (cycle time) of the equipment side beyond production time (cycle time) of this shortest installation pusher side and the fitting machine relatively, when time production time (cycle time) of the shortest installation pusher side is long, make the production time (cycle time) that pusher side is installed consistent with its time, when time production time (cycle time) of the shortest installation pusher side in short-term, in production time (cycle time) scope of production time (cycle time) equipment side beyond being no more than fitting machine of installation pusher side, the time is replaced in the shortening preparation that configuration is replaced based on component supplying apparatus, and obtains the new configuration of component supplying apparatus.As mentioned above, the production efficiency of whole erection streamline can be improved, beamhouse operation can be improved simultaneously.
The 3rd execution mode
Secondly, the 3rd execution mode of the present invention is described.Be applicable to that (therefore Fig. 1～Fig. 3) identical omits its explanation to basic structures such as the fitting machine that installation assembly line, this installation assembly line of the 3rd execution mode is included and the function of fitting machine component feeding portion with the 1st execution mode.Below, only difference is elaborated.
The installation assembly line 90 of the 3rd execution mode, basically identical with the 1st execution mode, obtain on which fitting machine 10, to distribute each installation exercise according to disclosed optimization method, and as the order of initial production program, make the order of carrying out the installation exercise that distributes on each fitting machine, on this basis, configuration corresponding to the component supplying apparatus on the current any fitting machine that is installed in installation assembly line 90, the substrate that divides pairing to produce object is installed the installation exercise of various elements, and can suitably change above-mentioned current production routine.
Particularly, as shown in Figure 7, the control device 99 of each fitting machine is being distributed among the installation exercise of this fitting machine, extracts the installation exercise that the component supplying apparatus installed with this fitting machine can not carry out.Then, obtain the configuration information of current component supplying apparatus in other fitting machines 10 by the network in the installation assembly line, and search can replace this fitting machine other fitting machines 10 of the installation exercise that can not carry out.Like this, if find other fitting machines 10, then in these other fitting machines 10, transmit and want the installation exercise information (installation data) that replaces, this fitting machine this installation exercise of then jumping over, and mobile installation exercise, consequently, can carry out the distribution of installation exercise corresponding to the configuration of component supplying apparatus.
The control device 99 of each fitting machine 10, carry out after fitting machine 10 distributes installation exercise, corresponding to the installation exercise that is distributed, formation by the position on the substrate, the element that should install, take out this element component supplying apparatus, carry out one group of data that head 41 that element transmits, erection sequence etc. constitute, and accumulate these data and carry out reconstructing of production routine.That is, these group of data is the installation exercises that distributed on corresponding each component supplying apparatus.When forming one group of data, take out the component supplying apparatus of element, at first select the device on being installed in fitting machine 10, and be recorded in the data in the lump with the installation site, if do not install, then its required component supplying apparatus is stored in the data as the predetermined component supplying apparatus of installing.
But, be not limited only to fitting machine 10 as the equipment that many component supplying apparatus can be installed, carry many belt feeders 35 and mobile heater car in addition, accommodate a plurality of charging trays 36 tray supply apparatus, can supply with the feed appliance etc. of the wafer of a plurality of lift-launch bare chips.These equipment carry, be connected on the fitting machine 10 or be configured on the close position of regulation.The head 41 of fitting machine 10, absorptive element from the component supplying apparatus of the regulation of these equipment transmits and is installed on the assigned position to substrate.
Like this, in the present embodiment, the control device 99 of each fitting machine 10 interconnects, and brings into play function as the installation exercise distributor.Wherein the installation exercise distributor corresponding to the configuration of each equipment, divides pairing to produce the installation exercise of the substrate of object to each component supplying apparatus.And, as the installation exercise distributor, comprise the control device 99 of other devices beyond the fitting machine 10, can be independent or many bring into play function.
As mentioned above, if supply with on any fitting machine that the component supplying apparatus of required element is installed in installation assembly line 90, then can alleviate installation that the operator carries out this component supplying apparatus, dismounting, mobile operation, therefore, can be easy to carry out preparation work.For example, when carrying out actual preparation work, the promising component supplying apparatus that carries out harsh product substrate and be provided with is installed in each equipment, therefore, is utilized this point can obtain good operability.
Then, in required element,, carry out preparation work by operator's installation elements feedway on any apparatus of installation assembly line 90 only to the element on any fitting machine that is not installed in installation assembly line 90.
But, like this, distribute installation exercise corresponding to the current component supplying apparatus that is installed on each equipment to each component supplying apparatus, according to the combination of the kind that is installed in the component supplying apparatus on each equipment with the substrate kind of producing object, the load of the installation exercise that carries out in each fitting machine may not keep distributing well balancedly.Particularly, when installation exercise concentrates on the specific fitting machine etc., occur comparing the fitting machine that becomes excessive bottleneck between installation exercise and other fitting machines, then may reduce the production efficiency of whole erection streamline.And, for each fitting machine, combination between the installation exercise that is distributed on the also configuration of the component supplying apparatus of being installed according to itself, configuration from the component supplying apparatus installed on the external equipment of component feeding to this fitting machine that carry out and the fitting machine thereof, head movement distance in each installation exercise is elongated, and by head simultaneously the chance of absorptive element tail off etc., may can not get high production efficiency.And, for the installation site of component supplying apparatus, also the situation that head can not take out element may take place.
At this, in the 3rd execution mode, the operator as preparation work on each equipment of installation assembly line during the installation elements feedway, its predetermined installation elements feedway of notification operator should not be installed can not the installation site and recommend the recommendation installation site of installing, and can prevent to cause to reduce the configuration of the component supplying apparatus of productivity ratio thus in advance.
Below, be that example describes with the situation of the installation elements feedway of each fitting machine own.
Can not the installation site, be to be judged as the position that this component supplying apparatus should not be installed, for example, can not take out element etc. not have the position of effect, the position that hinders other installation exercises or obstruction preparation work to installation exercise position etc. even install.
In the present embodiment, particularly, be can not the installation site with following set positions.(1) position that the head of the suction nozzle that is used for treatment element feedway institute feed element can adsorb only can't be installed; (2) disturb the position of (being necessary to dismantle installation elements feedway) with installation elements feedway; (3) the predetermined position that other component supplying apparatus are installed.
In the present embodiment, being calculated by the control device 99 of each fitting machine 10 can not the installation site, and show in the display unit 98 that each fitting machine possessed can not the installation site to go forward side by side to work and know, and these control device 99 and display unit 98 are as bringing into play function by the installation site notifying device.
Recommending the installation site, from whole erection streamline and productivity ratio viewpoint that the equipment of this component supplying apparatus is installed, is exactly desirable installation site.
In the present embodiment, recommend the installation site, be comprehensive judgement (1) according to production routine determine, (2) near element mounting position on the substrate and identification video camera etc., favourable to productivity ratio, (3) can realize equalization, (4) of load balancing between each equipment of installation assembly line do not have mounted component supplying apparatus, etc. all conditions and setting.
Figure 15 schematically shows the key diagram of receiving and sending messages between each fitting machine.Shown in 15 figure, each fitting machine is to connect also by network to carry out the transmitting-receiving of information.
Each fitting machine sends the information on load of (broadcasting) production routine desired installation exercises itself off and on to other all fitting machines.And each fitting machine receives other machine utilization information that send from other fitting machines.The communicator that the control device 99 of each fitting machine is possessed is brought into play function as the dispensing device that sends each fitting machine information on load to the outside.
And, on the network in this installation assembly line 90, connect the master computer (main PC) that constitutes by the personal computer of unified management whole erection pile line operation etc.Each fitting machine can obtain the total information of each component supplying apparatus and component kind mounted thereto etc.
So, each fitting machine, according to the information on load that obtains other fitting machines, and the balance of consideration and other fitting machine information on loads, can calculate the recommendation installation site that will be installed in component supplying apparatus own.
Figure 16 is the example of the tables of data of use when asking for each fitting machine load.Shown in Figure 16 (a), in the number of packages table that each production routine uses, on each fitting machine (fitting machine A, fitting machine B, fitting machine C), the installation exercise that distributes in the production routine corresponding to the substrate kind (kind A, kind B) of producing object is stored in each component kind (element A, element B, element C).And, if, just can calculate current load, therefore can revise the number of packages table that each production routine uses at any time corresponding to the distribution of the configuration change installation exercise of current component supplying apparatus.
And, shown in Figure 16 (b), in each fitting machine process capability counting rate meter, as showing each fitting machine (fitting machine A, fitting machine B ...) and the value of the combination of component kind, the erectility rate in the time of will be for reference for installation element (being element A in this example) is stored in each component kind (element A, element B, element C ...) in.For example, fitting machine A for element B can power rate be 80%, compare when hence one can see that with installation elements A, can only reach 80% speed.And, from production actual achievement feedback capability rate, and can upgrade at any time.
And, shown in Figure 16 (c), in each fitting machine process capability counting rate meter, store each fitting machine (fitting machine A, fitting machine B ...) ability (speed).For example, fitting machine A per hour has the ability of 20000 of reference for installation elements (being element A in this example) as can be known.
According to this data, the load of each fitting machine, available following formula is down obtained.
Load=(3600/ fitting machine process capability) * ∑ (number of packages/energy power rate)
(number of packages/energy power rate) is the element number of packages (number) when being converted into various elements as reference element (element A), these elements to all kinds are added up to, and be multiplied by (the 3600/ fitting machine process capability) that each reference element (element A) required time is installed in expression, obtain the load of the cycle time (inferring the production time) as each fitting machine thus.
In the present embodiment, be the calculating of loading by the control device of each fitting machine itself.And, obtain the information on load of other fitting machines according to the control device 99 of each fitting machine, and consider and the balance of other fitting machine load conditions, calculate the recommendation installation site of the component supplying apparatus that will be installed on this fitting machine.And the recommendation installation site of calculating is to notify by showing on the display unit 98 that each fitting machine possessed.That is, these control device 99 and display unit 98 are brought into play function as the notifying device of recommending the installation site.
Figure 17 is the flow chart that shows preparation work order in the installation assembly line.This preparation work is to carry out in the step S4 of Fig. 6.And the flow process that the whole base plate in the installation assembly line of the 3rd execution mode is produced is basic identical with Fig. 6 flow process that has illustrated, therefore, omits its explanation here.
As mentioned above, in the present embodiment, at first, corresponding to the configuration of current component supplying apparatus, distribute installation exercise to each fitting machine, the component supplying apparatus for supplying with short element carries out so-called preparation work by the operator.
As shown in figure 17, when carrying out preparation work, each fitting machine transmits the current information on load (step S130) of this fitting machine off and on mutually.
Under this state, as preparation work, want the operator (operator) of installation elements feedway on arbitrary fitting machine 10, read the identifying information (bar code) of wanting the installation elements feedway with the bar code reading machine 13 of fitting machine 10 (being equivalent to import the recognition device of the identifying information of recognition component feedway), and inquire the preparation work (step S132) of this component supplying apparatus to fitting machine 10 1 sides.If not inquiry (being NO among the step S134), then each fitting machine 10 turns back to information on load and transmits (step S130) mutually.
If the operator inquires (YES among the step S 134), this fitting machine 10 at first calculates this component supplying apparatus can not installation site (step S136).This can not the installation site calculating describe in detail hereinafter.
Then, this fitting machine is recommended the calculating (step S138) of installation site to this component supplying apparatus.The calculating of this recommendation installation site also will describe in detail hereinafter.
Recommend the installation site result calculated, if do not recommend installation site (NO among the step S140), then the operator dismantles the element of installing on current each equipment (step S142), it is produced recommend the installation site, and turn back to recommendation installation site calculating (step S138) again.
On the other hand, if recommendation installation site (YES among the step S140) is arranged, operator's installation elements feedway on any recommendation installation site of having notified then.Then, confirm component supplying apparatus and the position thereof that pusher side is installed is being installed, if be installed in can not the installation site on (YES among the step S146), then carry out mistake demonstration (step S148).
If the position of installing is not can not installation site (NO among the step S146), then corresponding to the position that this component supplying apparatus is installed, and change between the fitting machine as required or fitting machine in the production routine (step S150) of mobile installation exercise, and turn back to the mutual transmission step (step S130) of current information on load.
Below, according to the process description of Figure 18 calculate can not the installation site an example.Calculating that can not the installation site is in the control device 99 that will be carried out the fitting machine 10 that component supplying apparatus installs by the operator, obtains the component information (step S160) of this predetermined installation elements feedway institute feed element.This component information comprises the information such as suction nozzle of adsorbing this element.
Secondly, among a plurality of heads that head device 40 is possessed, extraction can be installed the head (step S162) of the suction nozzle of this element of absorption.If this head (YES among the step S164) not, then in this fitting machine 10, do not carry out the installation exercise of this element, and can not be installed on this fitting machine 10, therefore, show this information (step S166) of notifying by mistake, and finish can not the installation site calculating.
If this head (NO among the step S164) is arranged, just calculate the mobile range (step S168) of this head, and extract and position (installation site of component supplying apparatus) (step S170) to be set beyond the mobile range.And, as the attribute of this component supplying apparatus, but extract (step S172) such as its installation site and width.
Then, based on these information, obtain can not install position (step S174) is set.Particularly, for example, position that the head of the suction nozzle that is used to handle this element can adsorb only can't be installed for can not the installation site.And the position that takes place to disturb with mounted component supplying apparatus also is can not the installation site.These corresponding to the width of this component supplying apparatus adjacent be provided with on the position that the situation of installation elements feedway also belongs to can not the installation site.And existence can only be installed in this locational component supplying apparatus is set, and also is can not the installation site for this component supplying apparatus predetermined setting position is installed.
Can not installation site (NO among the step S174) if do not have, then with original state finish can not the installation site calculating.Can not installation site (YES among the step S174) if exist, then show can not the installation site after, finish (step S176).
Figure 20 be show can not the installation site the picture example.As shown in figure 20, for the component supplying apparatus that will install (element ARTSXX6), show mark, for example from the component supplying apparatus (position is set) of lower left component feeding portion No. 1 to No. 8, be that shade with dead color shows, represent that these positions are for can not the installation site.
Below, according to an example of the process description calculated recommendation installation site of Figure 19.This recommends in the calculating of installation site, carry out side by side the recommendation installation site in this fitting machine calculating and with reference to and other fitting machines between the calculating of recommendation installation site of load balancing.
The calculating of the recommendation installation site of this fitting machine, but be with extract to calculate above-mentioned can not the step S172 of installation site in states such as the installation site of predetermined installation elements feedway and width be prerequisite.Then, extraction and the irrelevant room of disturbing of installation elements feedway (step S190).If there is not room (NO among the step S192), judge then whether obsolete dismountable element (step S194) is arranged in this fitting machine.If dismountable element (YES among the step S194) is arranged, then shows dismountable element (step S195).If there is not dismountable element (NO among the step S194), then shows the information (step S196) that this component supplying apparatus can not be installed in this fitting machine, and finish the calculating of this recommendation installation site with mistake.And, when having shown detachable components, then dismantle this element by the operator, repeat to recommend the calculating (with reference to the step S142 of Figure 17) of installation site thus once more.And in the time of on can not being installed in this fitting machine, the operator attempts installing to other fitting machines.
On the other hand, if have and the irrelevant room of disturbing of installation elements feedway (YES among the step S192), then judge whether comprise in its room production routine specified position (step S198) is set, if comprise (YES among the step S198), then as the recommendation installation site of this fitting machine show production routine specified position (step S200) is set, and finish to recommend the calculating of installation site.
If not to be production routine specified in the room is provided with position (NO among the step S198), then and with the flow process that the load balancing between other fitting machines calculates merge.
And during the load balancing between other fitting machines calculates (step S202), seek other fitting machines (step S204) that load is lower than this fitting machine.If there are not this other fitting machines (not having among the step S204), the above-mentioned room that this component supplying apparatus then can be installed is provided with the position as candidate, and therefrom calculates the position (step S206) that helps producing.Then, show the position (step S200) that is beneficial to production, and finish to recommend the calculating of installation site as the recommendation installation site of this fitting machine.
If have load to be lower than other fitting machines (having among the step S204) of this fitting machine, then judge on these other fitting machines this component supplying apparatus (step S208) can be installed.If can not install, then the above-mentioned candidate at this fitting machine is provided with the position (step S206) that calculating helps producing in the position, and shows (step S200), and the calculating of installation site is recommended in end afterwards.
If load is lower than other installation functions of this fitting machine this component supplying apparatus (step S208) is installed, then be more suitable for being installed on these other fitting machines than this fitting machine, therefore, carry out demonstration (step S210), and finish to recommend the calculating of installation site to the installation indication of other fitting machines.And, receive the operator that indication is installed to other fitting machines, this component supplying apparatus should be installed on other fitting machines,, then on the display unit of other fitting machines, show and recommend the installation site if read the identifying information of this component supplying apparatus with the bar code reading machine of other fitting machines.
Figure 21 shows the picture example of recommending the installation site.As shown in figure 21, for the component supplying apparatus that will install (element PARTSXX6), the mark part that shows No. 26, the component installation location (position is set) of the component installation location (position is set) No. 13 (F013) of lower left component feeding portion and lower right component feeding portion, for example, be that blink states with light tone shows that these positions then show recommends the installation site.In operation indication hurdle, then seem in a jumble if show a plurality of recommendations installation site, therefore for example only show the little F013 of installation site numbering.
The installation assembly line related according to above-described present embodiment, because to the predetermined component supplying apparatus of installing, notice can not the installation site, and therefore, component supplying apparatus is installed in the reduction of the productivity ratio of can not the installation site and causing in the time of can preventing from advance to carry out preparation work.
And, because predetermined component supplying apparatus notice of installing is recommended the installation site, therefore, when carrying out preparation work, can improve each component supplying apparatus and be installed in the possibility of recommending on the installation site, and the reduction that can alleviate productivity ratio.On the other hand, if on any installation site the installation elements feedway, then distribute installation exercise according to the position of being installed, therefore, can realize the raising of operability.
And, owing to setting this recommendation installation site, therefore, can realize the equalization of the working load balance of each equipment based on the working load balance of each equipment, can realize the raising of whole erection flowing water productivity ratio.
More than, although understand the 3rd execution mode of the present invention, but be not limited only to the present embodiment said structure, as described below, can suitably change.
For example, in the above-mentioned execution mode, though must dismantle installation elements the position is set as can not the installation site,, can only can not take out also that element etc. can not be installed or the insignificant position that is provided with as can not the installation site etc., the suitable benchmark that setting can not the installation site.
And, in the above-mentioned execution mode,, preferentially set the specified position of production routine as recommending the installation site, but also can be preferentially the equalization of load balancing and determine to recommend installation site etc. between each equipment, suitably set the benchmark of recommendation installation site.For example, although the specified position of production routine is the room, also can preferentially loads small device and set and recommend the installation site.
And in the above-mentioned execution mode, though when recommending the installation site to recommend other equipment, notice has other equipment of recommending the installation site, also can notify the installation site of the recommendation in other equipment simultaneously.
And, in the above-mentioned execution mode, be the input unit that the bar code reading machine that possessed by fitting machine constitutes input element feedway identifying information, as long as but can import identifying information, be not limited only to this.For example, as input unit, wait the keyboard that connects on the computer that constitutes supervisory computer and each plant control unit etc. the identifying information (ID) of input element feedway also to be fine by operator.
And, in the above-mentioned execution mode, be that control device by each equipment (fitting machine) of installation assembly line carries out can not the installation site and recommend the calculating of installation site, but the supervisory computer of unified control installation assembly line is finished these functions and also is fine.
And, in the above-mentioned execution mode, each equipment (fitting machine) of installation assembly line though control device to distribute the installation exercise distributor of installation exercise to bring into play function to each component supplying apparatus, but, also the supervisory computer of unified management installation assembly line and the control device of particular device (computer) can be brought into play function as the installation exercise distributor, the installation exercise that each fitting machine then distributes like this.
The 4th execution mode
Secondly, the 4th execution mode of the present invention is described.The basic structure that is applicable to the fitting machine that the installation assembly line of the 4th execution mode and this installation assembly line are included is identical with the 1st execution mode (Fig. 1, Fig. 2), therefore omits its explanation.Below, mainly difference is elaborated.
The installation assembly line 90 of the 4th execution mode is also basic identical with the 1st execution mode, from improving the viewpoint of whole erection streamline 90 production efficiencys, distributing each installation exercise on which each fitting machine 10 is to obtain according to disclosed optimization method, and storage has distributed the production routine of installation exercise as initial production routine in the storage device that is provided with on the control device 99 of each fitting machine 10.Thus, can obtain high production efficiency usually.
Yet the elongated situation of installation exercise required time of distributing in advance can appear carrying out in prior uncertain interference such as generating device shortage and mistake sometimes in the actual installation streamline in the fitting machine that disturbs takes place.Following situation is for example arranged: because of switching running, generation equipment fault, the element of generating device shortage to the preparation element adsorbs wrong pilosity, sets the low usually running speed of ratio etc. for reducing element absorption mistake.
Then, if produce because of the influence that is subjected to this interference causes elongated fitting machine of activity duration, this fitting machine then becomes bottleneck, adds the long activity duration, standby time then occurs in other fitting machines of the activity duration weak point of formation installation assembly line.Promptly, for each machine that constitutes installation assembly line, elongated from moving into the streamline productive temp time of substrate till take out of, and the substrate of finishing installation exercise in the installation assembly line to withdraw from time interval of streamline elongated, and cause the reduction of whole production streamline production efficiency.
At this, in the related installation assembly line 90 of the 4th execution mode, in the production operation process, monitor the activity duration of each fitting machine, if long fitting machine of activity duration is arranged, then move the installation exercise that this fitting machine distributes and reduce the heavy burdens, and suppress the reduction of whole erection streamline production efficiency to other fitting machines.The mobile installation exercise here is meant, that carries out in certain fitting machine carries predetermined element operation (installation exercise) on the substrate, is replaced carrying out by other fitting machines.
This enabled condition as the activity duration of checking the installation exercise moving reference in the present embodiment, is based on the activity duration difference of each fitting machine and sets.Thus, corresponding to the destruction of the balance of each fitting machine activity duration, can suppress the reduction of whole production streamline production efficiency.
And, the enabled condition of activity duration, be based on the activity duration than under the long status the duration set.Thus, can suppress to cross the situation of fast response for the trickle external disturbance of eliminating in the short time.
And, in the present embodiment, the control device 99 of each fitting machine 10, monitor the activity duration of this fitting machine respectively, and judge whether to satisfy the enabled condition of afore mentioned rules, in the time of can not satisfying, then entrust the installation exercise of this fitting machine, realize moving of installation exercise thus to other fitting machines.Promptly, the control device of each fitting machine 10, as detection carry out the required activity duration of installation exercise checkout gear, judge whether the activity duration satisfy the judgment means of regulation enabled condition and installation exercise is brought into play function to the distribution mobile device that other fitting machines move.
Like this, in the present embodiment, because the control device 99 of each fitting machine 10 carries out various judgements, therefore, in this installation assembly line 90, receive and dispatch separately activity duration mutually as information on load between each fitting machine, also call the transmitting-receiving of mobile installation exercise information simultaneously as required.
Figure 22 schematically shows the key diagram of receiving and sending messages between each fitting machine.Shown in Figure 22 (a), each fitting machine, the required activity duration of installation exercise that itself is distributed sends (broadcasting) to other all fitting machines off and on as information on load (information on load of equipment itself).And each fitting machine receives the information on load (information on loads of other equipment) that other fitting machines send.The communicator that the control device 99 of each fitting machine is possessed is brought into play function as the communicator of the activity duration (information on load) that sends from each fitting machine to the outside.
Like this, in other fitting machines, obtain the activity duration each fitting machine of (information on load), activity duration (information on load) of the activity duration of this fitting machine (information on load) and other fitting machines relatively, judge whether move to other fitting machines the installation exercise of this fitting machine.
According to this judged result, if should move, the suitable extraction installation exercise that can move to other any fitting machines from the installation exercise of distributing to this fitting machine then.Then, shown in Figure 22 (b), in as other specific fitting machines of installation exercise moving target position, send the installation exercise movement requirement comprise the installation data that is used to carry out the installation exercise that will move.In receiving other specific fitting machines of this requirement, if can accept its requirement, then the fitting machine that moves original position to installation exercise sends information, and the fitting machine of mobile original position is received the information of accepting this requirement, then can confirm to distribute to the moving of installation exercise of this fitting machine.
Figure 23 is the key diagram that moves the installation exercise example when external disturbance takes place.Among Figure 23, interconnect and constitute installation assembly line, in the substrate (workpiece) of producing object process successively, carry out necessary installation exercise successively by fitting machine A, B, C, D by 4 fitting machine A～D.Among Figure 23, above-below direction shows elapsed time, and each line number word shows the activity duration (second) of each each fitting machine constantly.
As prerequisite, handle according to optimization arbitrarily and to distribute installation exercise, make the activity duration of each fitting machine A～D be 60 seconds.
Begin among upstream fitting machine A per 60 seconds the zero hour then by along moving into substrate A, B, C, D from producing, and side fitting machine B, C, D send downstream.On each fitting machine A～D, substrate is carried out in the stable state of installation exercise, because each fitting machine A～D finishes the required activity duration of installation exercise of being distributed and is 60 seconds, thus the streamline productive temp time be 60 seconds, the per installation exercise that can finish substrate in 60 seconds.
At this, suppose that fitting machine B goes up the generation external disturbance.The situation of the switching operating condition of preparation element for example, takes place to utilize because of the element shortage.And suppose that fitting machine B is subjected to this outside interference, the original 60 seconds activity duration becomes 90 seconds.At this moment, before the installation exercise of fitting machine B finished, upstream side fitting machine A can not send into next substrate, and can not send into next substrate among the fitting machine C of downstream, therefore fitting machine B becomes bottleneck, and the streamline productive temp time also extends to 90 seconds, and then finishes substrate in per 90 seconds and install.
If the state of external disturbance continue to take place in fitting machine B, although fitting machine B all with the installation exercise of finishing distribution in 60 seconds of stable state, and the streamline productive temp time remained 90 seconds.
If this state continuance (continuing to produce the time of 3 above substrates here) then distributes the part of the installation exercise that is distributed among the fitting machine B and temporarily mobile to other fitting machines A, C, D.In the present embodiment, thisly move the installation exercise of certain fitting machine and the processing of producing is called as dispersion treatment to other 1 or many fitting machines.In this dispersion treatment, make the installation exercise equalization of each fitting machine, and select mobile installation exercise and moving target position.
In this example, move the fitting machine B of a part of installation exercise and other fitting machines A, C, the D that receives installation exercise to other fitting machines, activity duration, whole equalizations turned to 70 seconds, and the streamline productive temp time of production line also be reduced to 70 seconds, and can suppress the state that production efficiency reduces.
In fitting machine B, take place external disturbance during, though continue the state of this dispersion treatment,, in case eliminated the interference of fitting machine B, then the activity duration among the fitting machine B also shorter than 60 seconds under the stable state, here be 50 seconds.This is because replaced an installation exercise part of having carried out original distribution by other fitting machines A, C, D.
If eliminated external disturbance like this, then finish dispersion treatment, the installation exercise of distributing to fitting machine B originally that temporarily moves to fitting machine A, C, D then turns back to fitting machine B, if each fitting machine works well, then turns back to the stable state that can obtain best production efficiency.
And, in the above-mentioned dispersion treatment, the activity duration of the installation exercise that moves to other fitting machines A, C, D from fitting machine B, it in the stable state 10 seconds ((after eliminating external disturbance) 50 seconds activity durations after the 60 seconds one stable state activity duration dispersion treatment), under the state that external disturbance takes place, it among the fitting machine B 20 seconds (70 seconds activity durations after the preceding 90 seconds one activity duration dispersion treatment of dispersion treatment).On the other hand, for these installation exercises, need to amount to 30 seconds among fitting machine A, the C in dispersion treatment, the D activity duration of (every activity duration * 3 that increased by 10 seconds from 60 seconds to 70 seconds).Like this activity duration inconsistent, be that fitting machine B can more efficiently handle installation exercise (short time) because initial allocation is suitable for fitting machine B for the installation exercise of fitting machine B sometimes.
Secondly, the operating sequence when carrying out this dispersion treatment according to flowchart text.
Figure 24 is the flow chart that shows the dispersion treatment order in this installation assembly line.Among Figure 24, among many fitting machines, shown that side by side the installation exercise of the installation exercise that the activity duration is distributed to other fitting machine trusts itself than growing moves the processing of the installation exercise moving target position of original position and this trust of reception.
As shown in figure 24, in the production operation process, carry out the dispersion treatment program side by side, each fitting machine transmits the information on load (activity duration) (step S220) of this fitting machine (equipment itself) off and on mutually.
Under this state, each fitting machine judges that this fitting machine (equipment itself) execution has distributed the required activity duration of installation exercise whether to satisfy enabled condition (step S222).
As judging the concrete example that does not satisfy this enabled condition, for example have: the activity duration of this fitting machine (1) requires at whole more than 20% of fitting machine average operation time; (2) require whole fitting machine average operation times the state continuance more than 10% through nearest 5 substrates with first-class.And, meeting in two of example conditions any one or with two all meet etc. under the situation, then be judged as and do not satisfy enabled condition etc., can carry out the combination of a plurality of little conditions and judge.And, when difference is judged based on activity duration of each fitting machine, as mentioned above, except comparing, can also compare with the shortest activity duration in other fitting machines with the average operation time.Perhaps can be according to comparing and judge with the regulation operation scheduled time (for example 60 seconds) of prior setting.
And, can whether be that predefined project is advanced judgement also according to long reason (interference) of activity duration.For example,, can use the situations such as switching running of preparing element, can be used as the project that begins dispersion treatment inspection in advance and set corresponding to the fault of element shortage and component supplying apparatus, component supplying apparatus situation by operator's dismounting etc.
And these enabled conditions are example, also can set other conditions.
If satisfy enabled condition (YES among the step S222), then need not mobile installation exercise from this fitting machine, therefore, can receive, and turn back in the mutual transmission of information on load (step S220) from the movement requirement of other fitting machine installation exercises.
If do not satisfy enabled condition (NO among the step S222), then extract and want the installation exercise (step S224) that moves.Want the installation exercise that moves, be with exist the used element mounting of its installation exercise other fitting machines of component feeding portion 30 and removable be prerequisite.Then, move the result of its installation exercise to other fitting machines, the activity duration of this fitting machine and other fitting machines more equalization turn to good.Wanting the installation exercise that moves, can be one or more.And, be distributed into when a plurality of for the installation exercise of similar elements, only move wherein a part and also can.And, become the fitting machine of installation exercise moving target position, can be 1 or many.The activity duration of many other fitting machines is preferably distributed a plurality of installation exercises and mobile in many other fitting machines when same degree.Do the further equalization of activity duration that then is easy to carry out this fitting machine and other fitting machines of Duo Tai like this.And, only move the installation exercise that this fitting machine distributed a part might as well, or move and all might as well.For example, even when this fitting machine can not carry out the state of installation exercise because of failure and other reasons becomes,, proceed the substrate production of whole erection streamline thus as might all moving on in other fitting machines then with the installation exercise that is distributed in this fitting machine.
If there is not movably installation exercise (NO among the step S226), then can not be from this fitting machine mobile installation exercise, therefore, can accept from the movement requirement of the installation exercise of other fitting machines, turn back to the mutual transmission step (step S220) of information on load in order to make it.
If movably installation exercise (YES among the step S226) is arranged, then extract the installation data (step S228) of wanting mobile installation exercise, and send (step S230) to the fitting machine that can become mobile original position as the installation exercise movement requirement.In this movement requirement, can comprise a plurality of installation exercises, and in the installation data of each installation exercise, comprise lift-launch coordinate data on element title and the substrate etc.And, when many fitting machines of wanting as moving target position are arranged, each fitting machine is sent movement requirement.
And, when mobile original position is in upstream side than moving target position, in the movement requirement of this installation exercise, comprise that the specific fitting machine that carries out installation exercise is in the information of producing substrate (below, related substrate is called dispersion treatment and is suitable for workpiece) under the state of change.As this information, for example, can enumerate substrate series management numbering and Lot Number etc.Comprise that this particular substrate information is because under the state of mobile installation exercise, is suitable for workpiece by the next specific dispersion treatment of producing of the device of upstream side.
Become in the installation pusher side of moving target position, receive the movement requirement (step S232) of installation exercise, then judge to receive this movement requirement (step S234).
For example, this judgement, be estimate whether the element surplus be used in the related installation exercise of movement requirement sufficient, whether this element is in this moving target position fitting machine in the switching running of preparation element and moving target position fitting machine when being in the upstream side of mobile original position, the substrate of the installation exercise object that this movement requirement is related has reached the production predetermined number, and the substrate production that whether has begun next kind etc. is carried out.
If can not accept movement requirement (NO among the step S234), then reply the information (step S236) of refusal movement requirement to mobile original position, mobile original position is received this refusal result (step S238), then turns back to want the installation exercise extraction step (step S24) that moves in order to check moving of other installation exercises.
If moving target position can be accepted movement requirement (YES among the step S234), then reply the information (step S240) of accepting movement requirement to mobile original position.When moving target position is in the upstream side of mobile original position, in the answer of accepting movement requirement information, comprises and determine that dispersion treatment is suitable for the information of workpiece.Comprising this information, is to be suitable for workpiece for the dispersion treatment of being determined by the upstream side device to be produced under the state of mobile installation exercise.
Accept like this in the fitting machine of moving target position of movement requirement, judge whether the substrate of producing object is that dispersion treatment is suitable for workpiece (step S242).Be suitable for workpiece (NO among the step S242) if not dispersion treatment, then before installation exercise is moved, continue under the state to produce, and wait for that dispersion treatment is suitable for the arrival of workpiece.If dispersion treatment is suitable for workpiece (YES among the step S242), then with the installation exercise of being accepted, in the installation exercise that the fitting machine by this moving target position carries out, appends processing, and be in dispersion treatment state (step S244).
On the other hand, the fitting machine of mobile original position receive movement requirement accept as a result the time (step S246), whether substrate that then judge to produce object is that dispersion treatment is suitable for workpiece (step S248).Be suitable for workpiece (NO among the step S248) if not dispersion treatment, then before making installation exercise, continue under the mobile status to produce, and wait for that dispersion treatment is suitable for the arrival of workpiece.If dispersion treatment is suitable for workpiece (YES among the step S248), then makes its installation exercise that can in mobile original position fitting machine, move, and carry out the jump processing of mobile installation exercise, and be in dispersion treatment state (step S250).Adopt this jump to handle to be because, the distribution of installation exercise is based on optimization calculating and obtains, and preferably eliminated in the distribution that external disturbance then turns back to initial installation exercise and begin to produce, thereby in the production routine of this fitting machine, do not eliminate mobile installation exercise.
Dispersion treatment state based on step S244 and step S250, the upstream side fitting machine of any side that at first is the mobile original position fitting machine of moving target position fitting machine, installation exercise with installation exercise begins, and, the substrate that carries out installation exercise based on this dispersion treatment arrives in the fitting machine of opposite side downstream, and begins in this fitting machine.This dispersion treatment state lasts till and eliminates (NO among the step S252) till the overload state.Whether eliminating overload state is can be judged by the activity duration in this fitting machine.
Do not had influences such as external disturbance if the mobile original position of installation exercise is installed pusher side, and eliminated overload state (YES among the step S252), then the moving target position fitting machine to installation exercise sends the information (step S254) that finishes dispersion treatment.When many other fitting machines have moved installation exercise, then send its information to each fitting machine.
Then, judge whether the substrate of producing object is that dispersion treatment is suitable for workpiece (step S256), if dispersion treatment is suitable for workpiece (YES among the step S256), then continues the dispersion treatment state.Be suitable for workpiece (NO among the step S256) if not dispersion treatment, then finish the jump of mobile installation exercise and handle, and turn back to (step S258) in the common production status.
On the other hand, the moving target position fitting machine of installation exercise is also received the information (step S260) that finishes dispersion treatment, judges then whether the substrate of producing object is that dispersion treatment is suitable for workpiece (step S262).If dispersion treatment is suitable for workpiece (YES among the step S262), then continue the dispersion treatment state.Be suitable for workpiece (NO among the step S262) if not dispersion treatment, then finish by moving the processing of appending of the installation exercise that appends, and turn back to (step S264) in the common production status.The upstream side fitting machine of any one party at first turns back to common production status in the mobile original position fitting machine of the moving target position fitting machine of installation exercise and installation exercise, and the substrate of having finished this common installation exercise arrives the opposing party's downstream fitting machine, when in this fitting machine, turning back to common production status, the dispersion treatment state of end step S258 and step S264.
Like this, if eliminated overload state and the long activity duration is recovered, then finish dispersion treatment, therefore, the distribution of installation exercise is very fast then to return to common production status, thereby can guarantee high productivity ratio.
Figure 25 when generating device is short in the production operation process, carries out the key diagram that installation exercise moves example.Shown in Figure 25 (a)～(b), the component supplying apparatus of feed element A, B, C is installed in upstream side fitting machine A, and has been distributed the installation exercise that carries these elements.And, the component supplying apparatus of feed element A, D, E is installed in the fitting machine B of downstream, and has been distributed the installation exercise that carries these elements.
With element A is example, then can find out to have carried a plurality of element A (for example 60) on each substrate, and substrate is carried a plurality of installation exercises of a plurality of element A respectively, and each half (for example each 30) are distributed among fitting machine A, the B.Therefore, in the substrate of in usually producing, producing (1), be that each half (each 30) of the element A that carries with fitting machine A and the element B that installs with fitting machine B constitute.
Here, suppose that downstream fitting machine B goes up certain interference, the situation that its activity duration is elongated of taking place.At this moment, the fitting machine B that the activity duration is elongated for the activity duration of equalization and fitting machine A, to having the fitting machine A of similar elements A, carries out the movement requirement of the installation exercise part (for example 12) about element A.And set among the fitting machine A accept its requirement and be through with whole installation exercises of substrate (2).
Then, shown in Figure 25 (b), moved into next substrate (3) among the fitting machine A, fitting machine A then will be appended and be carried out dispersion treatment by the installation exercise of fitting machine B trust., this moment, move into substrate (2) among the fitting machine B and be the substrate that is applied to before the dispersion treatment, therefore, fitting machine B does not carry out the jump of installation exercise to be handled, and identical installation exercise (individual to element A30) when carrying out with usual production.
Then, shown in Figure 25 (c), if move into the substrate (3) that is applied to dispersion treatment in the fitting machine B, the installation exercise that is undertaken appending by fitting machine A (for element A30+12=42) then as dispersion treatment, therefore, then cross mobile installation exercise among the fitting machine B, and only carry out remaining installation exercise (for element A30-12=18).
As mentioned above, according to present embodiment, if prior uncertain external disturbance takes place, and the fitting machine activity duration that external disturbance takes place is elongated and can not satisfy the enabled condition of regulation, then each fitting machine of installation assembly line carries out moving part or all of installation exercise that this fitting machine distributes to other fitting machines automatically, causes the reduction of whole erection streamline production efficiency thereby the fitting machine that can suppress to take place external disturbance becomes bottleneck.
And, set the enabled condition of activity duration based on the difference of activity duration of each fitting machine, therefore, the destruction of activity duration balance between each fitting machine can be directly judged whether to take place, and the reduction of whole erection streamline production efficiency can be suppressed.
And, basic operation in the time than under the long status the duration set the enabled condition of activity duration, therefore can suppress the fast response of crossing to the external disturbance eliminated in the short time.
And therefore distribution and mobile operating time, can make the further equalization of activity duration between each fitting machine, and can suppress the reduction of whole erection streamline production efficiency more accurately than the installation exercise of long fitting machine in many other fitting machines.
More than, though the 4th execution mode is illustrated, present embodiment is not limited only to said structure, can suitably change as described below.
For example, in the above-described embodiment, though carry out that in the control device of each fitting machine itself detection of each fitting machine activity duration, the judgement of whether satisfying regulation enabled condition and installation exercise move etc., but these can be by host computers of unified management installation assembly line etc. and carry out, and also can be unified to carry out by the fitting machine of any specific.
And, in the 1st to the 4th execution mode discussed above, though component supplying apparatus has adopted belt feeder and pallet, component supplying apparatus is not limited only to this, also can adopt as feeding in bulk and can supply with the component supplying apparatus of the other types such as feed appliance of the wafer that carries bare chip.
And, in the 1st to the 4th execution mode, in the fitting machine element mounting can be moved along a direction of principal axis with straight line to the head on the substrate, but also can move or can move along both direction in the plane along circumference.Though fitting machine is that example is illustrated to carry component supplying apparatus, also can links to each other, or get final product near being arranged on, so long as the element mounting of this feedway can be got final product to substrate with the peripheral component feedway.Installation assembly line involved in the present invention can be made up by a kind of in these various fitting machines or many and forms.
