2. Description of the Related Art Conventionally, a polyethylene box containing a plurality of small parts has been stored in each of the shelves of a parts warehouse in which a plurality of shelves are arranged in a plurality of rows. Then, the control device stores the position of each shelf and the type of the parts stored in the plastic box placed on the shelf. When the control device requires an arbitrary part, the control device stores the part. Move the stacker crane to the placement shelf of the poly box that is stored,
I took out a plastic box containing the necessary parts and placed it on the parts supply table, which is the parts outlet. Then, the operator took out the necessary parts from the plastic box on the parts supply table. When the poly box was not empty after the necessary parts were taken out after the parts were taken out, the control device returned the poly box to the original shelf by the stacker crane.

However, if one plastic box is stored in each shelf, there is a lot of wasted space and the storage efficiency is poor. Therefore, it has been attempted to store a plurality of plastic boxes in a stacked state. In this case, components of the same type were stored in the stacking component boxes. This is because the poly box located in the middle of the parts box could not be taken out, and the parts box was always taken out from the top or bottom. Also, if the plastic boxes are taken out from the top or bottom and returned to the same place, the stored parts will be lost. With this method, even if the plastic boxes are stacked to reduce unnecessary space and improve storage efficiency,
Since only the same kind of plastic boxes will be stored, it was not possible to meet the demand to store many kinds of parts on the premise of high-mix low-volume production.

To solve the problem, the applicant has
Japanese Patent Application No. 6-42632 proposes a component supply device that takes out a component box in which an arbitrary component is stored from a component box group in which a plurality of component box stages in which a component box in which an arbitrary component is stored is stacked. There is. The configuration of the component supply device is shown in FIG.
Description will be given based on a front view of the overall configuration shown in FIG. 5 and a side view of the overall configuration shown in FIG. The component supply device has a frame box structure in which the frames 101 are connected. The plastic box base 102 is fixed to the lower surface, and the positioning protrusion 114 is attached to the upper surface of the plastic box base 102 to position the lowermost plastic box P. The upper poly box P is positioned by the lower poly box P and six pieces are stacked to form a parts box step. Four parts box rows are provided to form a parts box group. In Fig. 25, the rightmost parts box forming the fifth row is a parts box for supply.

The lifting belt 1 is provided at the four corners of the frame 101.
03 is stretched up and down by pulleys 112 and 113. The pulley 113 is rotationally driven by the motor 118. An elevating slide 120 is slidably fitted to a guide shaft parallel to the elevating belt 103. The elevating slide 120 is connected to the elevating belt 103, and is vertically moved by driving the elevating belt 103. In addition, the elevating bracket 1 with the elevating slides 120 at both ends.
09 is attached. Four pairs of lever rotation mechanisms 110 are attached to the elevation bracket 109 at positions corresponding to each component box step. An upper plastic box lifting lever 111 is attached to each lever rotating mechanism 110, and the upper plastic box lifting lever 111 is rotated by the lever rotating mechanism 110 into an engaged state or an avoiding state with respect to the plastic box P.

Further, the lifting bracket 109 is shown in FIG.
A pair of left and right belts 105 are stretched in the left-right direction. In addition, the pair of left and right brackets 10 is slidable with respect to the guide shaft attached to the lifting bracket 109.

The left and right belts 105 are connected to each other and are always driven to symmetrical positions. A plastic box lever 108 is attached to the left and right brackets 107 via a lever rotation mechanism 116. The plastic box lever 108 is a lever rotation mechanism 11
6, the plastic box P is rotated to the engaged state or the avoidance state. Below the left center of the frame 101,
The component supply table 104 for placing the taken out plastic box P is fixed. Further, a cylinder 115 is attached to the lower right portion of the frame 101, and a moving table 117 is attached to the tip of the rod of the cylinder 115.

Next, the operation of the component supply apparatus having the above configuration will be described. As an example, an operation of taking out the plastic box PA located at the position of the fifth row from the top in the third column from the left in the drawing and moving it to the component take-out stand 104 will be described. First, as shown in FIGS. 25 and 26, the upper poly-box lifting lever 111 is engaged with the upper frame of each poly-box P on the fourth row from the left from the first row to the fourth row. The elevating belt 103 raises the elevating bracket 109. As a result, all the plastic boxes P from the first row to the fourth row and from the first row to the fourth row are lifted up. At the same time, the poly box lever 108
Is engaged with the third-row, fifth-stage poly box P, and the lower surface of the poly-box P and the upper surface of the other fifth-stage poly boxes P become a predetermined distance, and the elevating belt 103 moves the elevating brackets 109. Raise. Here, as shown in FIG. 26, before the poly box P is lifted, the distance between the poly box lever 108 and the poly box P is longer than the distance between the upper poly box lifting lever 111 and the poly box P. When lifted, there is a predetermined distance between the upper surface of the poly box P held by the poly box lever 108 and the lower surface of the poly box P held by the upper poly box lift lever 111.

Next, the left and right belts 105 are driven, and the left and right brackets 107 are moved right above the component supply base 104. Then, the plastic box P held by the left and right brackets 107
The lifting belt 1 up to the height at which the parts are placed on the parts supply table 104.
The lifting bracket 109 is lowered by 03. next,
The lever rotating mechanism 116 is driven to drive the poly box lever 108.
Is retracted from the plastic box P. Then, the elevating belt 103 lowers the elevating bracket 109 to a position where the lower surface of the first, second, and fourth rows of the fourth-stage poly box P completely contacts the upper surface of the fifth tier. Next, the first, second, and fourth rows of the upper plastic box lifting lever 111 are retracted by the lever rotation mechanism 110. Next, the lifting bracket 103 lowers the lifting bracket 109 to a position where the lower surface of the third-stage fourth-stage plastic box P completely contacts the upper surface of the sixth-stage. Next, the third row upper plastic box lifting lever 111 is retracted by the lever rotation mechanism 110. As a result, the number of stages of the third-row poly box P changes, but when the poly box P is returned after the parts are taken out from the poly box P placed on the parts supply base 104, the third box of the third box You can put it on the first row,
It can be returned in a short time.

On the other hand, the empty poly boxes P are sequentially stacked in the fourth row. When a plurality of empty poly boxes P are stacked in the fourth row, the cylinder 115 is driven and the moving table 11 is moved.
7 moves to the position of the fifth row. The operator takes out the empty plastic boxes P and places the same number of stacked poly boxes P as the taken-out poly boxes P on the moving table 117. Next, the cylinder 115 is driven to return the movable table 117 to the position of the fourth row. As a result, a new component box group is formed.

[0010]

However, in the conventional method, for example, Japanese Patent Application No. 6-426 proposed by the present applicant is proposed.
There were the following problems in controlling No. 32. (1) In the conventional control device, when a new poly box P is placed on a shelf, the information on the shelf position of the poly box P and the parts to be stored is registered, but the new poly box P is moved. Since there is no means for changing the information such as the positions of the box P and other poly boxes P, the positions of the poly boxes P taken out by the parts supply device proposed in Japanese Patent Application No. 6-42632 and the other poly boxes P Could not be dealt with. (2) In the conventional control device, since the shelf position from which the plastic box P is taken out and the shelf position to return the same are always the same, like the parts supply device proposed in Japanese Patent Application No. 6-42632,
It was not possible to control the component supply device that changes the position where the plastic box P is taken out and the position where it is returned. (3) In the conventional control device, by replacing the empty poly boxes P with the poly boxes P containing the parts one by one,
Since replenishment was performed, when replenishing a plurality of plastic boxes P, it was not possible to efficiently process the position information and storage part information of the plurality of poly boxes P.

The present invention solves the above problems and
By controlling a component supply device that takes out an arbitrary component box from a component box group having a plurality of rows of component box stacks of a plurality of component boxes, the position of another component box is changed by taking out one component box. Even so, it is an object of the present invention to provide a control device for a component supply device capable of accurately correcting changed component box information.

Through the display input / output interface 5, it is possible to monitor the situation and to record the history of the poly box P (work) delivered to the take-out section, the history of the poly box P (work) carried into the replenishment section, and the history of the abnormality occurrence. indicate. The data input of the spare parts is not limited to the bar code data, and an input method using the push button switch or the display device with a data input function 18 may be used. The history data collection device 22 also stores history data and prints it out.

The component box management controller 23 of this embodiment uses two CPUs, the main CPU 1 and the sub CPU 7. The purpose of this is to speed up the processing, and if there is no problem in processing time, Sub CPU8, ROM8, R
There is no problem even if the AM 9 and the shared memory 4 are not used and the bar code reader input interface 10 and the sequencer signal input interface 11 are directly incorporated in the main CPU 1.

Next, the operation of the component box management controller 23 having the above configuration will be described in detail with reference to the flowchart. An overview of the overall processing of the parts box management controller 23 is shown in FIG. 2 as a general flowchart, and detailed processing for various request processing in the general flowchart is shown in flowcharts in FIGS. When the power is turned on, the parts box management controller 23 performs an initial hardware check, memory initialization, sequencer 2
Initialization processing (S31) such as initialization of output to 0 and the like is performed. Next, a man-machine interface for updating various data displayed on the display device with data input function 18 and switching display screens corresponding to various display screen switching request keys input from the display device with data input function 18 A process (S32) is performed. Next, various parameter setting values input by the display device with a data input function 18 are received, and parameter setting / storing for rewriting the data stored in the internal RAM 3 or the shared memory 4 or performing new registration. Processing (S33) is performed. Next, sequencer input / output signal processing (S34) is performed to fetch various poly box movement request signals such as removal of empty poly boxes P and to send completion signals for them.

Next, a search is made to find in the parts box group or the replenishing section where the poly box containing the work necessary for manufacturing the vehicle type instructed from the outside is located, and the parts are supplied to the parts supply stand 104.
A plastic box take-out request process (S35) for updating the work data in the apparatus at the time of transporting is carried out. The details will be described later. Next, the presence / absence of a work in the poly box on the parts supply table 104 is determined, the return position is searched by each method according to the method, and the work data in the device when the poly box is returned is updated. Return request processing (S
36). The details will be described later. Next, when supplying the filled poly boxes in the replenishment section into the stock section, it is searched how many poly boxes in the replenishment section are received from which position in the replenishment section, and to which position in the stock section the stock boxes are delivered. A plastic box replenishment request process (S37) is performed to update the work data in the apparatus when the plastic box is delivered to the department. The details will be described later.

Next, the plastic box in the take-out section is forcibly made into an empty plastic box and returned to which position in the replenishing section (or the stock section if the replenishing section has a filled poly box or the empty poly box is full). Forced empty plastic box return request processing (S3) that searches whether or not to do and updates the work data in the device when the plastic box is returned
Perform 8). Here, when returning an empty plastic box to the supply department,
If there is a filled plastic box in the supply department or the empty plastic box is full, it is temporarily saved in an empty area in the stock department. The details will be described later. The position of the temporarily saved empty plastic box and the return position of the supply unit are searched, and the empty plastic box collection request process (S39) is performed to update the work data in the apparatus when the empty plastic box is returned. The details will be described later.
Next, in the case of an empty area where neither the filled poly box nor the empty poly box exists in the last row of the stock section (row closest to the supply section) (if there are multiple rows, the front row in the empty area) When one or more poly-filled boxes are stacked, find out to which position in the stock section all the refilled poly-filled boxes can be moved in a batch. A process for requesting replenishment of poly-filled boxes at once for updating work data in the apparatus (S40) is performed. The details will be described later.

Next, as a parts supply device, in order to deliver the plastic box in the stock section to the take-out section as soon as possible,
I want to transfer a little plastic box in the stock section to the front side (closer to the take-out section) in the idle time of the equipment. Therefore, how many poly boxes in the uppermost rear part can be simultaneously conveyed to the row with an empty area in front of them, the receiving position and the delivering position of each are searched, and the work data in the device is transferred when the poly box is delivered. A poly-box front-filling request process (S41) for updating is performed. The details will be described later. Next, use a barcode reader to read the work type of the poly box loaded into the replenishment section, the number of works in the poly box, etc.
A work information input process (S42) in the replenishment section poly box for transferring to the bottom of the empty area of the replenishment section is performed. The details will be described later. Finally, when there is a request from the history data collection device 22 for the various history data described above (S43, YES), a history data output process (S44) for transmitting the respective data stored in the RAM 3 in the file format is executed. To do. The details will be described later. The parts box management controller 23 uses the above-described S32.
The block from S44 to S44 is repeatedly executed.

Next, the detailed operation of each of the blocks S35 to S42 will be described in detail with reference to the flow charts of FIGS. As shown in FIG. 3, the plastic box take-out request process S35 is performed when the "poly box take-out request instruction" signal is input from the sequencer 20 (S46, Y).
ES), since the corresponding poly box position search completion memory is in the OFF state (S47, YES), the vehicle type data signal input at the same time is read and the work data D2 corresponding to the vehicle type is read.
(Representing the work type) is read according to a preset parameter (S48). Next, the poly-box data corresponding to the read work data D2 (the poly-box position data, the work data in the poly-box, the number of remaining works in the poly-box, and the same work storage order are shown) are shown in FIG. All are extracted from the table (S49). At this time, if there is no corresponding poly box (S50, NO), a signal "no poly box corresponding to the vehicle type" is output (S56), and the search ends.

When there is a corresponding poly box (S50, Y
ES) re-extracts the poly box (D4 (x, y) = 1) having the oldest same work storage order in the work data, and sets the poly box position data (indicating the column number and the column number) to “poly”. As the “box receiving position data” signal D1 (x1, y1),
After outputting the take-out part poly box position data to the sequencer 20 as a "poly box delivery position data" signal D1 (0, 0), a "data read instruction" signal is output as a trigger signal for the reading timing of the data (S52) ( This signal output is omitted in the following description). Further, since the number of poly-boxes to be simultaneously conveyed is one, the number of poly-boxes for simultaneous conveyance n = 1 is stored (S53).

After this processing, the first plastic box data transfer processing is carried out (S54). The details of the first processing of the plastic box data are shown in FIG.
It is shown in the flowchart. According to the instruction from the sequencer 20 (S206), when the transport unit of the component supply device receives the poly box PA of the stock section (or the replenishment section), the poly box receiving data update in the stock section is not completed (S207, NO), the number n of poly-conveyed boxes is read (S2
08). In this case, since the number of plastic boxes to be conveyed at the same time is 1, the column number x and the row number y of the poly box receiving position data are set.
Is read for n = 1 minute (S209) and transferred to the poly box data area of the transport unit (S210). Here, DTz (m) indicates the transport unit plastic box data. Next, the poly box P located at the upper stage of the poly box PA received from the stock section (or the replenishment section) by the transport unit.
The data of the poly box of No. is transferred in the lower direction by n = 1 (S211). Then, the poly box data of the taken out poly box PA is cleared (S212). In the component supply device of this embodiment, when the poly box PA is taken out, the poly box PA located at the upper stage of the poly box PA is taken out.
This is because it is necessary to change the information in the plastic box one step at a time because it has been unloaded to the position where it was.

For example, when the poly box PA in the third row from the left and the fifth row from the top is taken out, the column number x = 3 and the row number y = 5 of the poly box receiving position data of the poly box PA are set. The data is read (S209) and transferred to the plastic box data area of the transport unit (S210). Next, the poly box data of the first to fourth poly boxes P located at the upper stage of the poly box PA received from the stock section (or the replenishing section) to the transport unit is transferred downward by n = 1. (S21
1). Then, the poly box data D of the taken out poly box PA
Clear z (3,4) (S212). Next, "Completion of updating of plastic box receipt data in stock department (or supply department)"
The signal is output to the sequencer 20 (S213). By the processing described above, even when the position of another poly box changes when an arbitrary poly box P is taken out, the data of the changed poly box can be automatically changed. Therefore, a parts box in which a plurality of parts boxes are stacked is stacked. Even if an arbitrary component box is taken out from a component box group having a plurality of columns, the component information can always be accurately grasped.

Next, the second plastic box data transfer process (S5)
Perform 5). FIG. 16 shows the details of the second processing for transferring the plastic box data.
It is shown in the flowchart. When the transport unit carries the poly box PA to the take-out section and delivers the poly box, the sequencer 20 inputs a "take-out poly box delivery instruction" signal (S215, YES), and the transport unit poly The box data DTz (1) is transferred to the poly box data area of the extraction section (S216 to 218). After the transfer, a signal "completion of delivery of the poly box to the take-out section" is output (S21
9) Check that the same processing is not performed continuously (S)
216). Further, at the time when the "take-out plastic box delivery instruction" signal is turned off, the "take-out plastic box delivery completion" signal is turned off (S220).

In the poly-box return request processing S36, when the "poly-box return request support" signal is input from the sequencer 20 as shown in FIG. 4 (S58, YES), the poly-box return position signal search is not completed. Therefore (S59, NO), it is checked whether or not the plastic box in the take-out section has been delivered to supply the final work (S60). If it is the final work, it is judged that the poly box in the take-out section is empty, and the empty poly box is returned to the replenishment section. Therefore, it is determined whether or not there is an area to be returned to the replenishment section. A check is made by search processing (S69). The details of the supply section empty plastic box return search processing are shown in FIG. 5 as a supply section empty plastic box return point search processing flowchart. The replenishment unit replenishes a refill poly box to be newly loaded into the apparatus, and also serves as an area for removing an empty box out of the apparatus when there is no refill poly box.

In the replenishment section plastic box return point search processing S69, it is checked whether or not there is a replenishment section poly box in the replenishment section (S76).
If there is (S76, NO), it means that there is no area for returning the empty plastic box in the replenishment section, and thus "remember no replenishment section return location memory".
Is turned on (S81), the process of FIG. 5 is completed, and the process returns to S70.
If there is no filled poly box (S76, YES), then it is checked whether or not the empty poly box is full (S77), and if it is full (S77, YES), the "replenishment unit return point no memory" is set to O.
No (S81), the process is terminated and the process returns to S70. If it is not full (S77, NO), it is checked what area of the supply section is empty (S78 to 80), the supply section return plastic box position data is stored (S82), and the processing ends. To do.

As a result of the empty portion plastic box return location search processing shown in FIG. 5, if there is no area for returning the empty empty plastic box to the emptying portion (S70), or if the above-mentioned takeout area plastic box is the final workpiece, If not, the empty area is searched from the bottom of the stock section to the top of the front row (row closest to the takeout section), and then to the back row (S61 to S).
67), if there is no empty area in one place (S67,
YES), there is no place to return the empty box, so that the "no return place" signal is output to the sequencer 20 (S6).
8). If there is an empty area (S63, YE
S), the position is output as a "poly box delivery position data" signal, and the take-out section is output as a "poly box delivery position data" signal together with a "data read instruction" signal (S7).
1). At this time, since the number of poly boxes to be conveyed is n = 1, "1" is stored in the "number of poly boxes for simultaneous conveyance" (S72).

After these processes, the third plastic box data transfer is executed.
Processing is performed (S73). Fig. 17 shows the data transfer of the plastic box No. 3
A processing flowchart is shown. In response to an instruction from the sequencer 20 (S221, YES), when the transport unit of the component supply device receives the poly box of the take-out section, the data of the poly box is transferred to the poly box data area of the transport unit section (S223). At this timing, since it was confirmed that one work was taken out from the poly box in the take-out section, the number of remaining works in the poly box is reduced by one (S224).

As a result, when the work in the plastic box is exhausted (S225, YES), "the same work storage order updating process in the stock section and the replenishment section S226" is performed. The details of this process are shown in the flowchart of FIG. After the replenishing section, the frontmost row of the stock section is searched from the lowest row to the upper row, and then to the rear row for a poly-box containing the same type of work as the work of the transport unit section (S240), and the storage order of the poly-box is stored. If is a plastic box older than the storage order of the transport unit section (S241, YES), the storage order is updated by one new one (S242). This is sequentially carried out for all areas of the replenishment section and then the stock section (S
243-S246).

After that, all the poly-box data in the transport unit except the poly-box position data are cleared (S227).
When all the processes are completed, the "take-out section plastic box receiving data update complete" signal is turned on (S228), and the above-mentioned process is not repeated (S222). Further, when the "take-out plastic box reception instruction" signal is turned off, the "take-out plastic box reception data update completion" signal is turned off.

Next, the process proceeds to S74 in FIG. 4, and the fourth plastic box data transfer process is performed. For details of this process, see FIG.
8 shows a flow chart. According to the instruction signal from the sequencer 20 (S230), the number n of the poly-boxes conveyed by the conveyance unit at the same time is read (S232), and then the column number and the column number of the stock section (or the replenishing section) for delivering the poly-boxes are read. (S223). Next, all the plastic box data of the transport unit is transferred to the stock section (or the replenishment section) (S234). Next, the transport unit plastic box data is cleared (S235). Finally, the signal "completion of update of delivery data of poly box in stock part (or supply part)" is output to the sequencer 20 (S236). Further, when the "in-stock section (or supply section) plastic box delivery instruction" signal is turned off (S230, NO), the "stock section (or supply section) plastic box data update completion" signal is turned off (S237).

Next, the plastic box replenishment request processing S3 shown in FIG.
7 will be described with reference to the flowchart of FIG. In response to an instruction from the sequencer 20 (S83, YE
S), from the bottom of the front row to the top of the stock section (S8
5 to 89) and then to the back row (S90 to 91) to search for an empty area. When there is an empty area, the replenishment section take-out position data and the simultaneous conveyance poly-box number search process (S93) are performed. Details of this process are shown in the flowchart of FIG. In the process of FIG. 7, first, it is checked whether the poly box in the replenishment section is a poly box, a blank poly box, or no poly box (S98). If there is no poly box (SS98, YES) ), A "replenishment section filled with no poly box" signal is output to the sheather 20 (S107), the number of poly boxes for simultaneous conveyance is cleared (S108), the process of FIG. 7 is terminated, and the process returns to S94.

If the replenishing section has a poly-filled box (S98,
No), it is checked whether or not there is a plastic box in the next upper row of the empty area in the stock section (S99 to S10).
6). In other words, if there is a plastic box on the next higher row in the same row, the poly box cannot be transported from the replenishment section to the stock section through that step, so the number of simultaneously transported poly boxes is reduced by one. It needs to be processed. Further, when there is a poly-box in the next-row / one-stage above, the number of simultaneously-conveyed poly-boxes is reduced, and the same check is performed for the upper stage. If there is a poly-box up to the top, the number of simultaneously-conveyed poly-boxes becomes one, and the process proceeds to the receiving position search process of the poly-box in the replenishing section (S99 to S106).

Next, the uppermost stage of the polyfilled boxes in the replenishment section is first searched (S109 to 111), and the number of stages is compared with the number n of simultaneously conveyed polyboxes obtained in the above process ( S11
2) If the number of stages y4 is larger, that is, if there are more than one poly-filled boxes in the replenishment section, the poly-box receiving position data is calculated (S115) and the process ends. When the number n of simultaneous conveyance poly boxes is larger than the number y4 of stages (S112, YE
S), the number y4 of simultaneously-conveyed plastic boxes is set to the number n of filled poly boxes in the replenishing section (S113), and the receiving position is also changed to the lowermost section of the replenishing section y4 = 1 (S114). After the above processing of FIG. 7 is completed, the process returns to S94 of FIG. For the sequencer 20,
The poly box position data of the stock section is output as a "poly box delivery position data" signal, the poly box position data of the replenishing section is output as a "poly box delivery position data" signal, and then a "data read instruction" signal is output ( S94). After this processing, the above-mentioned first plastic box data transfer processing (S95),
The fourth plastic box data transfer process (S96) is executed and the process ends. Since the plastic box replenishment request processing S37 is performed, the maximum number of poly boxes that can be transported is determined by determining the number of empty boxes and the presence or absence of poly boxes on the same row behind the row, and the number of poly boxes of that number is determined. Since the boxes can be transported at the same time, the plastic boxes can be efficiently moved from the replenishment section to the stock section.

The details of the forced empty plastic box return request processing S38 are shown in the flowchart of FIG. When the signal from the sequencer 20 is input (S116, YES), the empty plastic box return position search completion memory is OFF (S117,
(YES), first, the number of works remaining in the plastic box in the take-out section is set as the final work (S118).
Next, it is checked whether the replenishment section is not replenished with the refilled poly box (S119), and if there is the replenished poly box (S1
19, YES), from the bottom row to the top row of the front row of the stock section,
Next, in the rear row direction, or if there is no filled plastic box, first search the empty area where the empty plastic box can be returned in the same manner as above from the bottom to the top of the replenishment section (S).
120-126,128).

If an empty area is found during the search (S1
22, NO), the search process is terminated, and "the number of poly boxes simultaneously transported"
Is stored as one (S129). Then, the retrieved empty area position data is output as a "poly box delivery position data" signal, and the takeout part position data is output as a "poly box delivery position data" signal together with the "data read instruction" signal to the sequencer 20 (S130). Also, if no empty area is found even after the entire search is completed (S1
26, YES), “No return point” signal is sent to the sequencer 2
It is output to 0 (S127), and the search ends. After these processes, the above-mentioned third plastic box data transfer process (S13)
1), the fourth plastic box data transfer process (S132) is executed and the process ends. The "poly box receiving (and delivering) position data" signal and the "data reading instruction" signal are turned off when each request instruction signal from the sequencer is turned off (S117).

The details of the empty plastic box collection request processing S39 are shown in FIG.
It is shown in the flowchart. When the signal from the sequencer 20 is input (S134, YES), since the data read signal output is OFF (S135, YES), whether the replenishment section is replenished with the replenishing poly box (S136) or empty poly box. It is checked whether the box is full (S137). If either (S136, NO or S13
(7, YES), a "replenishment section no return point" signal is output. (S141). Otherwise (S136, YE
S and S137, NO), the position of the empty area of the supply unit is sequentially searched from the bottom (S138 to 140), and when found, the column number is stored and the process proceeds to S142.

Next, the presence / absence of an empty poly-box temporarily placed in the stock section and the position of the poly-box are searched according to the empty poly-box position search process in the stock section (S142). The details of this search processing are shown in the flowchart of FIG. Front row x7 of stock part (S147), bottom row y7
From (S148), it is sequentially checked whether or not there is an empty plastic box in the area within the stock section (S149). If there is no (S149, NO), the upper stage is sequentially performed (S150 to 15).
1), and then search to the back row (S152 to 153). When an empty plastic box is found (S149, YE
S), storing the position data of the area (S155),
The number of simultaneously conveyed works is set to 1 (S156), and the search process ends. In addition, as a result of searching all areas in the stock section, if no empty plastic box is found (S15
(3, YES), the signal "no empty plastic box in stock part" is output (S154), and the process ends. Based on the result, the position of the empty plastic box in the stock section is used as a “poly box receiving position data” signal, and the empty area of the replenishing section is used as a “poly box delivery position data” signal together with the “data reading instruction” signal and the sequencer 20. Is output to (S143). After a series of these processes, the above-mentioned poly-box data transfer first process (S144) and poly-box data transfer fourth process (S145)
And then exit.

FIG. 11 is a flow chart showing the details of the process S40 for requesting the replenishment of the poly-filled boxes collectively. When the signal from the sequencer 20 is input (S157, YES), the data read signal output is OFF (S158, YE).
S) Then, it is checked whether or not the replenishing section is replenished with the replenished plastic box (S159). If not (S159, YE
S), outputting a "no filled poly box" signal and ends the process (S
165). If there is (S159, NO), it is checked whether or not there is any plastic box in the last row of the stock section (row closest to the supply section) (S160 to 161). If there is a plastic box (S161, NO), a "no replenishment point" signal is output and the process ends (S165).

If there is no poly box (S161, YE
S), and further repeats the check in the front row direction (S1)
62-164). On the way, when the line in which the poly box exists is found, or when the check is completed up to the front line (S16
2, NO or S163, NO), and the column number of the empty area is stored (S162A). Then, the position data at the bottom of the row in the empty area is used as the "poly box receiving position data" signal, the position data at the bottom of the replenishment section is used as the "poly box receiving position data" signal, and they are used as the "data read instruction" signal. It is output to the sequencer 20 (S166). At this time, since the number of the poly boxes for simultaneous conveyance is all in one row, Y pieces are set (S167). After this series of processes, the first plastic box data transfer process (S168) and the fourth plastic box data transfer process (S169) are executed, and the process ends. By performing the filling poly box collective replenishment request process S40, the parts information can be converted even when a plurality of unneeded poly boxes are replaced with new poly boxes, so that the parts information of the poly box can be accurately and promptly. You can figure it out.

FIG. 1 shows the details of the plastic box front-loading request processing S41.
2 shows the flowchart. When the signal from the sequencer 20 is input (S171, YES), the data read signal output is OFF (S172, YES).
The empty area in the stock section is searched for in the empty area position search process (S173). The details of this search processing are shown in the flow chart of FIG. In this search process,
Front row x10 of stock part (S188), bottom row y10
The empty areas in the stock section are sequentially searched from (S189) (S190). Then, if an empty area is found (SS190, YES), the position data is temporarily stored (S196), the number of stacks of poly boxes on the upper part of the empty area is calculated, and the value is calculated by the simultaneous transfer poly. The number of boxes is provisionally stored (S197), and the search process ends. If it is not an empty area (S190, NO), the upper area is searched sequentially (S191 to 192), and if the search is completed up to the uppermost area, the search is further continued in the rear row direction (S193 to 194). . When the empty area cannot be found in the stock section at the time when the search of all areas is completed (S194, YES), a "no empty area in stock section" signal is output (S195), and the search process is ended and S1 is executed.
Return to 74.

As a result of this search, when there is no empty area in the stock section (S174, NO), the signal "no front-fillable poly box is available" is output (S183), the poly box search is completed, and the process proceeds to S186. . If there is an empty area (S174, YES), it is determined whether there is a poly box in the stock section in the rear row of the empty area, in the last row (S175),
The search is performed from the top (S177) (S178). However, if the column to be searched is the same column as the empty area searched by the empty area position search process in the stock part, a "no packing before possible poly box" signal is output (S183), and the search for the poly box is terminated.

The search is performed from the upper stage to the lower stage, and when the search is performed up to the lowest stage (S179 to 180), the next search is performed in the front row. When a poly box is found (S178, YE
S), comparing the number of steps y9 and the number n of simultaneous transfer poly boxes stored temporarily during the above-mentioned stock area empty area position search processing. If the number of steps y9 is equal to or more than the number n of simultaneous transfer poly boxes, the poly box is received. The position is stored as a step number below the retrieved step by the temporary storage of the number of simultaneous transfer poly boxes, and if the number of steps n is less than the number of simultaneous transfer poly boxes y9, the step number is the lowest step, and the number of simultaneous transfer poly boxes n is that number. The number of poly boxes stacked in a row is used (S18
4). As a result, the position data of the empty area is used as the "poly box delivery position data" signal, the poly tooth position data of the one to be taken is the "poly box receiving position data" signal, and the poly box position data of the one to be taken is the "poly box receiving position data". The "position data" signal is output and these are output together with the "data reading instruction" signal (S185). After this process, the above-mentioned poly-box data transfer first process (S186) and poly-box data 1 transfer fourth process (S187) are executed and the process ends. By performing the plastic box front-filling request process S41, it is possible to move the plastic boxes in the rear row farther from the parts take-out front to the front in the idle time when the parts supply device is not performing work such as taking out parts. It is possible to reduce the time taken by the component supply device to take out components.

(8, YES), the work type sent from the barcode reader 19, the number of works in the plastic box, etc. are temporarily stored (S199). Next, the filled poly box is searched from the empty area of the replenishment section or the stage having the empty box from the bottom (S200) (S201). Then, if it is not the empty area or the empty plastic box (S201, NO), the search is sequentially performed to the upper stage (S202 to 203). If no empty area or empty plastic box is found even after performing a full search (S203, YE
S), the signal "no empty area in the replenishment section" is output (S20
4), the process ends. If an empty area or an empty plastic box is found (S201, YES), the data read by the barcode reader is stored at the position of that row (S2).
05), the work data, the number of remaining works, and the storage order are cleared for the replenishment section data area above that stage (S205A), and the process ends.
