[0022]
The film cutting machine 12 and the core supply device 1308 to which the component supply method and apparatus of the present invention are applied are basically configured as described above. Next, the operation thereof will be described.
[0023]
First, prior to the cutting operation of the film roll 14 by the film processing cutting machine 12, production plan data relating to the types of the wound bodies 30a to 30d and 30a 'to 30d' is sent from the management computer 1010 via the process control computer 1008. 1330. The control circuit 1330 stores the supplied production plan data in the production plan data memory 1334 and controls the film winding device 10 constituting the film processing cutter 12 through the input / output unit 1338 according to the production plan data. To do. For example, the arrangement of the cutting means (not shown) is adjusted according to the production plan data relating to the widths of the wound bodies 30a to 30d, 30a 'to 30d', the diameter of the core 28, and the winding direction of the long film 16, and the wound body It is determined whether 30a to 30d and 30a 'to 30d' are manufactured in the first winding part 1102A or the second winding part 1102B.
[0024]
Next, after the film winding device 10 has been adjusted as described above, the control circuit 1330 instructs the core supply device 1308 to supply the core 28 to be used according to the production plan data. Therefore, the supply operation of the core 28 will be described according to the flowcharts shown in FIGS.
[0025]
In the description of the flowchart, A # 1 and A # 3 are necessary for the wound bodies 30a, 30a 'and 30c, 30c' manufactured by the first winding unit 1102A in the film winding apparatus 10 shown in FIG. B # 2 and B # 4 represent winding length data and winding diameter data of the winding core 28, and B # 2 and B # 4 represent winding bodies 30b, 30b 'manufactured by the second winding section 1102B in the film winding apparatus 10. The core length data and core diameter data of the core 28 required for 30d and 30d 'are shown. S1C / V and S2C / V represent the core length data and core diameter data of the core 28 supplied to the transport mechanisms 1320 and 1322 in the core supply device 1308 shown in FIG.
[0026]
The control unit 1331 reads the data A # 1 of the core 28 necessary for manufacturing the winding bodies 30a and 30a 'in the first winding unit 1102A from the production plan data memory 1334, and the core in the core supply device 1308. Data S1C / V of the core 28 conveyed to the conveyance mechanism 1320 of the loader 1314 is read from the core data memory 1336, and these data A # 1 and S1C / V are compared (step S1).
[0027]
When A # 1 = S1C / V and it is determined that the desired core 28 is supplied to the transport mechanism 1320 of the core loader 1314, the length of the core 28 supplied to the transport mechanism 1320 and The diameter is measured (step S2). The length of the core 28 is measured by a core length measuring device 1342 provided in the transport mechanism 1320 and supplied to the control unit 1331 via the input unit 1346. Further, the diameter of the core 28 is measured by a core diameter measuring device 1344 disposed in the core transport robot when the core 28 is gripped by a core transport robot (not shown) that transports the core 28. The data is supplied to the control unit 1331 via the input unit 1346.
[0028]
When it is determined that the measurement result coincides with the data S1C / V related to the desired core 28 (step S3), the core transport robot transfers the core 28 supplied to the transport mechanism 1320 to the film winding device. 10 is loaded onto the transport mechanism 1326 corresponding to the A-axis side (the first winding unit 1102A side) (step S4). When the winding core 28 is loaded on the transport mechanism 1326, the process proceeds to a process of supplying the winding core 28 to the winding bodies 30b and 30b ′ (step S11).
[0029]
When the measurement result does not coincide with the data S1C / V related to the desired core 28 (step S3), there is a problem in the data or a problem in the supply operation of the core 28 in the core supply device 1308 The core transport robot loads the core 28 supplied to the transport mechanism 1320 onto the discharge unit 1324 (step S5). When the core 28 is loaded on the discharge unit 1324, the processing for the next core 28 can be repeated, or the operation of the core supply device 1308 can be stopped to check the situation.
[0030]
In step S4, when an appropriate core 28 is loaded onto the transport mechanism 1326, the controller 1331 obtains the core length data, the core diameter data, and the production plan data memory 1334 of the core 28, Tracking data composed of winding direction data of the wound body 30a or 30a ′ supplied with the winding core 28 is generated, and this tracking data is stored in the memory area ME1 of the tracking data memory 1340 corresponding to the transport mechanism 1326.
[0031]
On the other hand, if it is determined in step S1 that A # 1 ≠ S1C / V, the control unit 1331 causes the data S2C / V of the core 28 to be transported to the transport mechanism 1322 of the core loader 1314 in the core supply device 1308. Is read from the core data memory 1336 and compared with the data A # 1 (step S6). Thereafter, in the same manner as in steps S2 to S5, the core 28 supplied to the transport mechanism 1322 is loaded onto the transport mechanism 1326 on the A-axis side of the film winding device 10, or as an incompatible core 28. Loading into the discharge unit 1324 (steps S7 to S10).
[0032]
Next, the control unit 1331 reads the data B # 2 of the core 28 necessary for manufacturing the winding bodies 30b and 30b ′ in the second winding unit 1102B from the production plan data memory 1334, and the core supply device 1308. The data S1C / V of the core 28 conveyed to the conveyance mechanism 1320 of the core loader 1314 is read from the core data memory 1336, and these data B # 2 and S1C / V are compared (step S11). Thereafter, in the same manner as in steps S2 to S5, the core 28 supplied to the transport mechanism 1320 is loaded onto the transport mechanism 1328 on the B-axis side of the film winding device 10, or as an incompatible core 28. Loading into the discharge unit 1324 (steps S12 to S15).
[0033]
In the memory area ME2 of the tracking data memory 1340 corresponding to the transport mechanism 1328, the core length data, the core diameter data of the core 28 supplied to the winding body 30b or 30b ′, and the winding body 30b. Alternatively, winding direction data of 30b 'is stored.
[0034]
On the other hand, if it is determined in step S11 that B # 2 ≠ S1C / V, the control unit 1331 causes the data S2C / V of the core 28 to be transported to the transport mechanism 1322 of the core loader 1314 in the core supply device 1308. Is read from the core data memory 1336 and compared with the data B # 2 (step S16). Thereafter, in the same manner as in steps S12 to S15, the core 28 supplied to the transport mechanism 1322 is loaded onto the transport mechanism 1328 on the B-axis side of the film take-up device 10, or as an incompatible core 28. Loading into the discharge unit 1324 (steps S17 to S20).
[0035]
The winding core 28 for the wound body 30a or 30a ′ is supplied to the transport mechanism 1326, and the winding core 28 for the wound body 30b or 30b ′ is supplied to the transport mechanism 1328. These cores 28 are transported in the next stage. After being transported to the mechanisms 1316 and 1318, the supply process of the winding core 30c or 30c ′ and the winding core 28 to the winding body 30d or 30d ′ is performed similarly (steps S21 to S40).
[0036]
The core 28 supplied from the core supply device 1308 is conveyed to the film cutting machine 12 together with the tracking data added thereto. That is, when the core passing detector 1348 detects that the core 28 has been transported from the transport mechanisms 1326 and 1328 of the core loader 1314 to the transport mechanisms 1316 and 1318, the control unit 1331 stores it in the memory areas ME1 and ME2. The tracked tracking data is copied to the memory areas ME3 and ME4 corresponding to the transport mechanisms 1316 and 1318.
[0037]
Similarly, as the core 28 is transported from the transport mechanisms 1316 and 1318 to the transport mechanisms 1302 and 1306, the transport mechanisms 1300 and 1304, the first winding unit 1102A, and the second winding unit 1102B, tracking data is also recorded. Copied sequentially from ME3 and ME4 to ME5 and ME7, ME6 and ME8, ME9 and ME10.
[0038]
By moving the tracking data together with the core 28 in this way, information on the core 28 can be correctly transmitted by the tracking data, and an inappropriate core 28 is supplied to the film cutting machine 12. Can be avoided in advance.
[0039]
The tracking data also includes data on the winding direction of the wound bodies 30a to 30d and 30a 'to 30d' to be supplied. For example, in the transport mechanisms 1302 and 1306, the winding core 28 is moved to the A axis, It can be determined whether to supply to the B axis, the A ′ axis, or the B ′ axis.
[0040]
