The guide rail 40 is provided with a guide 41 for aligning the stacked trays 11 on the tray holder 37 on the extension line below the holder rail 36 of the tray stand 35.

The tray transfer means 39 transfers the tray 11 dropped on the guide rail 40 as described above to a position above the tray table 14 of the tray lifter 13 descending along the guide rail 40. In this embodiment, moving pieces 42 that are slidably moved along a piece guide 43 disposed in parallel with the guide rails 40 on the frame base 1 are arranged. The tray transfer means 39 is constituted.

The moving piece 42 is moved forward and backward by a rodless cylinder (not shown), and is engaged with one side edge of the tray 11 dropped on the guide rail 40, so that the tray 11 is provided at the portion where the tray lifter 13 is disposed. The stopper 44 (see FIG. 6) provided at the position is moved to a position where movement is restricted.

Next, the operation of the unloading device of the above embodiment will be described.

When the refrigerant tubes W are supplied over the tables 2 in an upright state by the screw conveyors 3, 3, the refrigerant tubes W are received by the tube holder 8, and the refrigerant tubes W are held upright.

As described above, the tube holder 8 advances in the tube feeding direction in synchronization with the feeding speed of the refrigerant tubes W, and stands up and holds the successively fed refrigerant tubes W in a stacked state.

At about the same time as the start of feeding the refrigerant tubes W onto the tables 2 and 2 by the screw conveyors 3 and 3, or during the feeding period, the tray holder 37 of the tray supply means 34 operates to retreat and the tray stand 35 The lowermost one of the empty trays 11 stacked on the tray is dropped onto the guide rails 40, and the moving piece 42 of the tray transfer means 39 moves forward along the piece guide 43 to move the empty tray 11 to the guide rails. The sheet is transported to a position where it comes into contact with the stopper 44 along the position 40, and is set at a position immediately above the tray table 14 of the tray lifter 13 that is descending.

The tube holder 8 is used for the tables 2 and 2
When the required number (for example, 100) of the refrigerant tubes W are stacked on the tables 2 and 2 in a stacked state, the tray lifter 13 is lifted by the lift operation. The empty tray 11 is raised by the table 14 between the tables 2 and 2, and the laminated refrigerant tubes W are taken in between the pair of side walls 12 and 12.

In the course of raising the tray lifter 13 to a predetermined height above the tables 2, 2,
Flanges 12a, 12a contact the tray catcher 22 and rotate it upward.

At the same time when the flanges 12a and 12a pass through the tray catcher 22, the tray catcher 22 returns to the original horizontal position, and then the tray lifter 13 moves down, so that the tray 11 in which the refrigerant tube W has been taken in moves. The flange 12a is locked on the tray catcher 22, and the tray catcher 22
Is held.

When the tray lifter 13 is moved down to the predetermined lowering position, the tube holder 8 is moved back to the original position, and the coolant tubes W are again fed onto the tables 2 by the screw conveyors 3. On the other hand, 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 thereafter, this operation is automatically repeated.

When a predetermined number of the trays 11 containing the refrigerant tubes W are stacked and held on the tray catcher 22, the tray lifter 13 is lifted to the unloading height position of the disposition height of the tray unloading section 30 during the final stacking operation. At the time of the operation, the tray pusher 24 is advanced, and the stacked plural trays 11 are pushed once to the tray unloading section 30 and loaded.

As described above, according to the unloading device of the present embodiment, the required number of the refrigerant tubes W fed from the refrigerant tube forming line (not shown) is erected on the tables 2 and 2 and bundled in a stacked state. Since this can be automatically taken in by the tray 11 and loaded into the tray carrying-out section 30, the omission can be realized by automation of the loading operation.

Here, in the present embodiment, the refrigerant tubes W sent to the tables 2 and 2 in an upright state by the screw conveyors 3 and 3 are held in the upright state by the tube holder 8. Can be arranged on the tables 2 and 2 in an orderly manner, so that the tray 11 can take in the data reliably.

Further, since the tray table 14 of the tray lifter 13 has the transfer roller 18 for transferring the tray 11 toward the tray discharge section 30, the tray 11 is pushed by the tray pusher 24 as described above. At this time, the tray 11 can be smoothly transferred from the tray table 14 to the tray discharge section 30.

Further, since the tray 11 placed on the tray table 14 is positioned by the stopper pin 19 and its displacement toward the tray discharge section 30 is regulated, not only the work of taking in the refrigerant tube W but also the tray 11 Can be stably transferred to the tray unloading section 30.

Further, a plurality of empty trays 11 are stacked and held at a position offset to one side of the tray lifter 13 by the tray supply means 34, and the guides of the transfer means 39 are sequentially arranged from the lowest one. Since the tray 11 dropped on the rail 40 and 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 carried out.

In the above-described embodiment, the loading of the condenser refrigerant tubes W has been described in detail as an example. However, it is needless to say that the present invention can be applied to the loading operation of other strip-shaped parts.
