As shown in FIGS. 1 and 4, along the endless circulation route 1, three inner endless power supply rails 31 and two outer endless power supply rails 32 for transmitting and receiving signals are arranged in a rack. 3 through a supporting bracket 30. Then, among the racks 3, a specific rack 3, in Figure 1, 5 racks 3 are considered as one group, and specific racks 3 No. 01, No. 06... No. 46 at one end of each group are selected.
In a, there is a current collector 33 in sliding contact with the power supply rail 31.
and a current collector 34 that is in sliding contact with the power supply rail 32, and the power supply unit 1 of this particular rack 3a is
The input terminal of the detection unit 19 and the current collector 33 are electrically connected, and the signal exchange terminal of the detection unit 19 and the current collector 34 are electrically connected. or,
Power is supplied from the specific rack 3a side to the power supply unit 17 of the other racks 3 in the same rack group by means of a cable 35 stretched between the lower parts of the racks 3.
The detection unit 19 and the current collector 34 on the specific rack 3a are connected via a cable 36 stretched between the upper parts of the rack 3. The pulse generator, which is a pulse signal source, is placed in the power supply unit 17 of one rack 3 (which may be the specific rack 3a) within one rack group, and The other racks 3 are supplied with the necessary pulse signals via the cables 35.

Cable 35 stretched between the lower parts of the rack
hangs down between the racks 3, and its central portion is connected to the center link pair 13 located between the racks of the endless drive chain 13, as shown in FIG.
The cable 36, which is supported by the groove-shaped receiver 37 attached to the upper part of the rack and is stretched between the upper parts of the racks, hangs down between the racks 3.
Its central portion is suspended by a clip 38 attached to the connecting link 14 between the racks.

Next, how to use it will be explained.

Although not shown, the endless drive chain 13
Each rack 3, 4 connected in an endless manner is driven by a motor to drive the driving wheel that hangs the racks, and rotates the endless driving chain 13.
rotates on the endless circulation path 1 while being guided by the guide rail 10 and the grooved rail 12.

When each rack 3 reaches a predetermined stopping position facing the product loading/unloading entrance 8, the driving of the endless drive chain 13 is stopped, and the rack 3 is stopped.
The work of transporting the aged product from the furnace chamber 18 in the rack 3 and the work of transporting the product to be aged into the furnace chamber 18 of the empty rack 3 can be carried out automatically using, for example, a transport device. to be done. After this loading/unloading work, the endless drive chain 13
is rotated to move each rack 3 intermittently in circulation.

The inside of the furnace chamber 18 of the rack 3 is heated by the sliding contact between the power supply rail 31 and the current collector 33, which is always operated by the power supplied via the power supply unit 17 regardless of the rotational position of the rack 3. and a circulation fan 22 driven by a motor 23 operated by the electric power, an atmosphere at a predetermined temperature is forcedly circulated. The product is subjected to an aging test for a predetermined period of time, for example, within the time required for the rack 3 to intermittently go around the endless circulation path 1, with the DC voltage supplied via the power supply unit 17 being applied. receive.

If the atmospheric temperature in the furnace chamber 18 exceeds the set temperature while performing the aging test as described above, or if the opening/closing door 20 opens for some reason, such an abnormality may occur. An abnormal temperature detection signal or an open door state detection signal is transmitted from the detection unit 19 of the cable rack 3, and this signal is transmitted to the cable 3.
6 or directly from the collector 34 to the power supply rail 32, and the power supply rail 32 sends the detection signal to the control device, and in order to stop the aging of the rack 3 in the abnormal state, the power supply unit The control signal is conversely transmitted from the power supply rail 32 to the rack 3 in an abnormal state via the current collector 34,
Only the aging of rack 3 in the abnormal state is automatically stopped. Of course, even if this abnormal condition occurs, the intermittent circulation movement of each rack 3, 4 will continue as usual.

In the rack 3 after the predetermined time required for aging has elapsed, the atmosphere heating action in the furnace chamber 18 is terminated, and the forced exhaust fan 27 is operated while the circulation fan 22 continues to operate. As a result, the high temperature atmosphere in the furnace chamber 18 is rapidly discharged from the exhaust pipe 25 into the endless exhaust duct 5, and the furnace chamber 18
8 is rapidly cooled down.

As explained above, the aged product is transported out of the rack while the rack 3 housing the product is accurately stopped at a predetermined position opposite the product loading/unloading entrance 8. .

When each rack 3 rotates through both U-turns of the endless circulation path 1, the adjacent racks 3 spread out in a fan shape, so that the cables 35 and 36 spanned between these racks 3 are A groove-shaped receiver 37 attached to the endless driving chain 13 whose length does not change between adjacent racks 3.
and a clip 38 attached to the same connecting link 14, so that even when the rack 3 rotates in a fan-shaped manner through the U-turn, the cables 35, 36 are not unduly disconnected. I don't feel like I'm being held back.

The present invention can be implemented and used as described above, in which a plurality of racks, each equipped with an electric device, are movably supported on a guide rail installed along an endless circulation path, and each of these racks is movably supported. , connected in an endless manner by links (in the embodiment, the center link pair 13a of the endless driving chain 13 and the connecting link 14) having a rotation locus that substantially coincides with the guide rail, and constructed along the endless circulation path. A current collector that is in sliding contact with the power supply rail is provided only in a specific rack among the plurality of racks, and a cable is electrically connected to the current collector between another rack that does not have the current collector and the specific rack. This cable is supported by the link between the racks, and the electrical equipment of each rack is electrically connected to the power supply rail via the current collector and cable. Compared to the case where a current collection means is installed in a rack, the equipment cost can be greatly reduced and maintenance can be made easier. Moreover, the cables between the racks required to achieve this effect can be easily installed. Even when rotating around the U-turn part of the endless circulation path, power can be supplied and control signals can be safely and reliably delivered without being unduly pulled or swung around and caught on other objects. obtain.

In addition, when implementing the present invention, as shown in FIG.
Second specific racks 3b (racks No. 05, No. 10, . . . No. 49) are equipped with a preliminary current collector 39 connected in parallel to the current collector 33 of a through the cable 35. By providing the main collector 33
