[0051]
At the same time as the flanges 12a and 12a pass through the tray catcher 22, the tray catcher 22 returns to its original horizontal position, and then the tray lifter 13 is moved down so that the tray 11 that has taken in the refrigerant tube W has its flange 12a. Is retained on the tray catcher 22 and held by the tray catcher 22.
[0052]
When the tray lifter 13 is lowered to a predetermined lowering position, the tube holder 8 is moved backward to the original position and the screw conveyors 3 and 3 feed the refrigerant tubes W onto the tables 2 and 2 again. In the same manner as described above, the empty tray 11 is set to a position immediately above the tray table 14 of the tray lifter 13 by the tray supply means 34 and the tray transfer means 39, and this operation is automatically repeated.
[0053]
When a predetermined number of trays 11 having taken in the refrigerant tubes W are stacked and held on the tray catcher 22, the tray lifter 13 is lifted up to the stacking height position at which the tray unloading unit 30 is disposed during the final stacking operation. Then, the tray pusher 24 is operated to advance, and the plurality of stacked trays 11 are pushed to the tray carry-out unit 30 at a time and loaded.
[0054]
As described above, according to the loading device of the present embodiment, the required number of refrigerant tubes W fed from the refrigerant tube forming line (not shown) are raised on the tables 2 and 2 and bundled in a stacked state. 11 can be automatically taken in and loaded onto the tray carry-out section 30, so that the omission can be realized by automating this loading operation.
[0055]
Here, in the present embodiment, the refrigerant tubes W that are sent up onto the tables 2 and 2 in the upright state by the screw conveyors 3 and 3 are held in the upright state by the tube holder 8. , 2 can be arranged in an orderly manner and can be reliably taken in by the tray 11.
[0056]
Further, the tray table 14 of the tray lifter 13 includes the transfer roller 18 for transferring the tray 11 toward the tray unloading unit 30, so that when the tray 11 is pushed by the tray pusher 24 as described above, The tray 11 can be smoothly transferred from the table 14 to the tray carry-out unit 30.
[0057]
In addition, since the tray 11 placed on the tray table 14 is positioned by the stopper pin 19 and the displacement movement toward the tray unloading section 30 is restricted, the tray 11 is unloaded as well as the refrigerant tube W is taken in. The transfer operation to the unit 30 can be performed stably.
[0058]
Further, a plurality of empty trays 11 are stacked and held at a position offset in the one side direction of the tray lifter 13 by the tray supply unit 34, and the guide rail 40 of the transfer unit 39 is sequentially installed from the lowest one. Since the dropped tray 11 can be transferred onto the tray table 14 of the tray lifter 13 by the moving piece 42, the empty tray 11 can be smoothly fed into the tray lifter 13.
[0059]
In the above embodiment, the stacking of the refrigerant tube W for the capacitor has been described as an example, but it is needless to say that the present invention can be applied to other strip plate-like parts.
