ンを複数ライン設けていた。 Conventionally, for example, when integrating an integrated circuit chip (hereinafter abbreviated as IC) into a circuit board, an integrated production process was used in which the steps of circuit board supply, IC die bonding, heating, wire bonding, resin molding, and characteristic inspection were performed in an integrated manner. The line is known.
The process with the lowest cycle efficiency on this production line is the wire bonding process, and the speed of each process on this production line is determined accordingly. Therefore, although there is still sufficient capacity for processes other than wire bonding, conventionally multiple lines of the same type have been set up in order to increase production volume.
そこで本発明は、上記先行技術の欠点に鑑みて
生産ラインの本数を増設することなく生産数量を
上げることを目的とする。 In view of the drawbacks of the prior art described above, the present invention aims to increase the production quantity without increasing the number of production lines.

なくワークＷを搬送切替装置２８に送り続ける。 In FIG. 2, if the roller feeder 1 on the first conveyance path A is "empty" (no work exists), the work W is fed from the previous process and the roller feeder 1 is activated. The workpiece W is advanced by the feed roller 12 of the roller feeder 1 (see FIGS. 4 and 5). When the tip of the workpiece W reaches near the end point (right end) of the roller feeder 1,
When the previous work is present at the next conveyance switching device 28 (the branch point in FIG. 1), the operation of the roller feeder 1 is temporarily stopped, and the work W is made to wait at that position. When the conveyance switching device 28 becomes “empty”,
The roller feeder 1 is restarted and the workpiece W is sent to the transport switching device 28. In the above description, if the transport switching device 28 is already in the “empty” state when the leading end of the work W reaches near the end point of the roller feeder 1, the roller feeder 1 continues to feed the work W to the transport switching device 28 without stopping. .
そこで搬送切替装置２８の搬送用ベルト３４

ト３４上をワークＷが搬送される。 Therefore, the conveyance belt 34 of the conveyance switching device 28
(See FIGS. 8, 9, and 10) is activated, and the workpiece W is conveyed on this belt 34.

込まれ、所定の加工が為される。 Here, if both the belt conveyors 2 of the bypass conveyance path B1 and the first conveyance path A are "empty", the conveyance direction of the work W is preferentially switched to the bypass conveyance path B1 side. That is, when the workpiece W reaches the position shown by the chain line in FIG. 8, the drive of the conveyance belt 34 of the conveyance switching device 28 is stopped, and the conveyance belt 25 of the bypass conveyance path B1 is activated. Therefore, as shown in FIG. 9, the conveyance switching device 28 is entirely lowered downward, whereby the workpiece W is transferred onto the conveyance belt 25 of the bypass conveyance path B1 .
The belt 25 transports the material toward the processing device C1 shown in FIG. In Figure 2, the processing equipment
If C 1 is processing the previous work, the drive of the belt 25 is stopped just before the end point transfer switching device 37 of the bypass transfer path B 1 as shown by the chain line, and the processing device C 1 becomes “empty”. You will be made to wait until When the processing device C 1 becomes “empty”, the conveyor belt 25 of the bypass conveyance path B 1 (see Fig. 8)
is restarted and the conveyance switching device 37 at its end point
is forced to fall downward. When the workpiece W reaches the end position, the drive of the conveyance belt 25 is stopped and the conveyance switching device 37 is raised. As a result, the workpiece W is transferred to the belt of the conveyance switching device 37, and sent to the processing device C1 by this belt, where a predetermined processing is performed.

まれる。 In the above, when the workpiece W is sent to the position indicated by the chain line in FIG . W is sent as it is to the belt conveyor 2 side by the transport switching device 28. Therefore, the feed roller 15 of the belt conveyor 2
is activated to pull in the work W, and the conveyor belt 21 is also activated to move the work W forward by the belt 21. In FIG. 2, when the workpiece W is sent to the vicinity of the end point of the belt conveyor 2, if another workpiece is present on the next belt conveyor 4, the belt conveyor 2 will temporarily stop, but the belt conveyor 3 will become "empty". Then, the belt conveyor 2 is restarted and the workpiece W is sent to the belt conveyor 3, by which the workpiece W is sent toward the next conveyance switching device 38. If the conveyance switching device 38 is “empty”, the workpiece W is fed into the conveyance switching device 38, and thereafter the workpiece W is transferred to the bypass conveyance path B2 or the belt conveyor 4 in the same way as the operation of the conveyance switching device 28 described above. selectively sent to. Conveyance switching device 40
In this case, the workpiece W is always switched to the bypass conveyance path B3 . The work W transported by the bypass transport paths B 2 and B 3 is sent to the processing devices C 2 and C 3 via the transport switching devices 39 and 41 at the respective end points in the same manner as described above.

The processed work W' is discharged from C 3 to the respective transport switching devices 42, 44, 46, and is further pulled out to a predetermined position by each transport switching device 42, 44, 46. And each conveyance switching device 42, 4
4 and 46 descend downward, the processed workpiece W' is transferred to each of the bypass conveyance paths D 1 , D 2 , and D 3 , and transferred to the second conveyance by each of the bypass conveyance paths D 1 , D 2 , and D 3 . It is transported towards route E.

W′の搬送動作は上記と全く同様に行なわれる。 The operation of transferring the processed work W' of each of the bypass conveyance paths D 1 , D 2 , D 3 to the second conveyance path E is performed as follows. In FIG. 3, when there is another processed work on the belt conveyor 48, the processed workpiece W' on the bypass conveyance path D1 is temporarily moved from the bypass conveyance path D1 to the position shown by the broken line in front of the conveyance switching device 43. It will stop working and stand by in that position.
If the belt conveyor 48 is "empty", the bypass conveyance path D 1 stops operating when the processed workpiece W' is conveyed to the conveyance switching 43 position (at this time, the conveyance switching device 43 is in the lowered position). do. By raising the conveyance switching device 43 upward and activating it, the processed workpiece W' is sent to the belt conveyor 48, and then
8 to the right. When this processed workpiece W' is conveyed to the vicinity of the end of the belt conveyor 48, if there is another processed workpiece on the next belt conveyor 49, the belt conveyor 48 is temporarily stopped, and the processed workpiece W' is transferred to the belt conveyor 49. 48 is placed on standby near the end. When the belt conveyor 49 becomes "empty", the belt conveyor 48
is restarted and the processed workpiece W' is delivered to the belt conveyor 49. When the processed workpiece W' is conveyed by the belt conveyor 49 to the vicinity of its end, the processed workpiece W' is not at the broken line position on the second conveyance path D 2 and the belt conveyor 50
If "empty", the processed workpiece W' on the belt conveyor 49 is sent to the belt conveyor 50 through the conveyance switching device 45. Further, when the processed workpiece W′ transported by the bypass transport path D 2 reaches the broken line position at the same time as the belt conveyor 49 side or earlier than that, the transport switching device 4
5 descends, and the processed workpiece is sent onto it via the bypass conveyance path D2 . And conveyance switching device 4
5 rises again to receive the processed workpiece W', and sends it to the belt conveyor 50. Processed workpieces on belt conveyors 50, 51, bypass conveyance path D3 , and conveyance switching device 47
The transport operation of W' is performed in exactly the same manner as described above.
