After that, the transport pallet 6 on the transport conveyor device 25 in the unit O is carried into the traverser 3b in FIG. 6 and moved in parallel downward, and is carried out to the forward conveyor device 26 in the unit O. After that, the transport pallet 6 is sequentially transported in the order of the units O to A by the transport conveyor devices 26 in the units O to A, is carried into the traverser 3a, and moves upward in parallel to the transport conveyor device 25 in the unit A. Be shipped. Although illustration of the units A to I is omitted in FIG. 10, the transport and forwarding conveyor devices 25 and 26 in the units A to I also operate in the same manner as in the case of the units J to O, and each of the units A to I. 12, the assembly of the power supply device 30 and the like are performed by the various machine tools used in the steps A to I shown in FIG.
It is carried out in sequence.

As described above, in this embodiment, a pair of upper and lower conveying and forwarding conveyer devices 25, 26, a drive motor 27 for driving each conveyer chain 4 of each conveyer device 25, 26, and each conveyer device 25, 26 transport chains 4
A multi-joint robot 9a for processing or assembling the transfer pallet 6 placed on the transfer pallet 6 and the power supply device 30 placed on the transfer pallet 6, multi-axis screw tighteners 11a and 16a, a Cartesian coordinate robot 24, and the like. Unit-type product production in which a single housing 50 accommodates a dielectric strength measuring device 19 for measuring the electrical characteristics of the machine tool or power supply device 30, an output voltage measuring device 20b, a measuring device 21 and other measuring devices. Device 7
Since a plurality of 0s are connected and the traversers 3a and 3b are connected to the start end and the end of the plurality of unit type article production apparatuses 70, the article production line system is configured, so that the article production line can be easily installed and moved. be able to. Also,
Since the unit-type article production apparatus 70 can be easily moved as shown in FIG. 6, the unit-type article production apparatus 70 can be added or deleted to freely add or delete the manufacturing process of the article production line. Furthermore, by inserting the unit device for manual work 71 shown in FIG. 11 into a part of each unit of the article production line system shown in FIG. 6, it is possible to easily add the manufacturing process by the manual work of the worker.

The embodiment of the present invention is not limited to the above embodiment, and can be modified. For example, in the above-described embodiment, the transport and forwarding conveyor devices 25 and 26 in the unit type article production apparatus 70 are respectively placed in the upper and lower mounting portions 50 of the housing 50.
Although an example in which they are placed on a and 50b has been shown, the conveying and forwarding conveyor devices 25 and 26 may be placed side by side on the horizontal plane of the upper placing portion 50a so as to be separated from each other. When a plurality of the unit type article production apparatuses are connected to form the article production line system shown in FIG. 6 of the above embodiment, the traverser 3 connected to the start end and the end of the plurality of unit type article production apparatuses.
As a and 3b, those capable of moving the transport pallet 6 in parallel in the horizontal direction are used. Also, one drive motor 27
Alternatively, the conveying and forwarding conveyor devices 25 and 26 may be driven via transmission means such as a transmission pulley.

Furthermore, the present invention is not limited to the production line of electric products such as power supply devices and can be applied to the production lines of all products.

[0029]

As described above, according to the present invention, since it is possible to easily install, move, and change the process of the article production line, it is possible to set the article production line that can be applied to various lot sizes. Moreover, it becomes possible to set up an article production line according to the form of the factory.
