Further, the machine frame 1 may be provided with a frequency selection push button switch. Stoppers 20.2 with shock absorbers are installed on the sides of the above-mentioned chain conveyors 11 and 110, respectively.
0' to move the mover 1"3 to one of the short conveyors 11
At that position, the conveyor 11 is raised by the short conveyor lifting device 21 and stopped on the rail 2.2 by the stopper 22 as shown in FIGS. 3 and 4. The pin 24 provided on the mover 13 is fitted into the U-shaped pin receiver 23 formed on the pallet 6, and in this state, the output terminals 25, 25, 25' provided on the mover 13 (terminal 25' is connected to the ground). ) is formed so as to be connected to input terminals 6, 26, and 26 provided on the pallet 6, and constitutes an electrical and mechanical connection device 27 between the mover 13 and the pallet 6. The short conveyor 11 is connected to the pallet 6 as shown on the right side of Figure 1.
The ° pin 24 of the slider-3 is fitted into the U-shaped pin receiver 23 of the stopper 2, and the input/output terminals 25 and 26 are connected.
By lowering the lifting device 21 from the solid line position in FIG.
Both terminals 25 and 26 are separated to form an electrical and mechanical separation device 28 between the pallet 6 and the mover 13. In addition, what is shown by 29 in the figure is the pallet 60 wheel, 30 is a guide roller that contacts both sides of the rail 20, and 31
is a stopping roller for the pallet 6, 32 is a guide roller for the mover 13, 33 is a chain drive device for the upper and lower conveyors 10.10, 34 is a chain drive unit for the short conveyor 11.11, and 35 is a chain drive unit for the Koshiveyor 4. 36 is a detached outlet on the pallet 6; 37 is a driving cylinder for the elevating/lowering M position 21; 38 is an elevating guide column; 39 is an elevator that fits into the vertical column 38; 40 is an elevating arm by the cylinder 37; 41 is a link between the arm 40 and the elevator 39, 42 is a connecting fitting between the elevator 39 and the short conveyor 11, 11, and 43 is a wheel of the mover 13.

In the present invention, the pallet 6 being transferred by the conveyor 4 on the rail 2.2 is stopped by the stopper 22, and in response to the stop signal, the short conveyor 11, which is located at the imaginary line on the left side of FIG. The mover 13 stopped on the conveyor 11 and the pallet 6 are electrically and mechanically connected I'i as described above. And push button switch 1B
, 19 to select the required frequency and voltage.

In this state, the stopper 22 is located at the solid line position in Figure 4.
rotates 90 degrees to the imaginary line position, and the stopper 22 and roller 3

Palette 6
and the mover 13 connected to this is the upper conveyor 1
'0 and away from the power supply line 12.12, the mover 13
moves onto the short conveyor 11' on the right side of FIG.
It is separated from the pallet '6 by 28, the operation of the equipment on the pallet 6 is stopped, and then the stopper 22 is opened and the pantoro is transferred to the right in FIG. Mover 1
3 descends with the short conveyor 11' from the 1 line position on the right side of FIG. 11 and stopper '-20
The chain 11'' of the parfocal conveyor 11 is stopped and raised to connect with the pallet 6, and the chain 11'' of the parfocal conveyor 11 is reversed, and the same operation as described above is repeated.

Since the present invention is based on the above-mentioned method and apparatus, it is possible to use the operating frequency at the time of trial run or break-in operation of televisions, videos, and other home appliances that are placed on the pallet 6 of the pallet conveyor 4 and automatically assembled during transportation. Not only is it not necessary to provide two assembly layouts for each frequency, but the required voltage is selectively supplied from the outside of the pallet 6, so there is no need to provide a voltage regulator for each pallet, which significantly reduces equipment costs. This has the effect of saving money and efficiently performing test runs or break-in runs for each transport model using the pallet 6 in one layout.
