Abstract

PROBLEM TO BE SOLVED: To certainly and softly land a coil on a floor by oscillating an L type frame around its corner part as its center by reversing means and moving the coil in such a way to make it contact with a coil support surface of a delivery side arm part by coil moving means. SOLUTION: A receiving side arm part 10a or a delivery side arm part 10b of an L type frame 10 can be reversed through a lever 15 by oscillating the frame 10 around a fixed shaft 13 as its center along the horizontal surface by telescopically driving a hydraulic cylinder 18. A walking beam 2 is devised to cross with a coil support device 11 in the vertical direction and move as its head end gets in and out of the inside of a movable frame 11c of the coil support device 11 at the time when the receiving side arm part 10a of the L type frame 10 is positioned along the horizontal surface. That is, it is possible to deliver a coil in a side hole state supported on a skid 2a on the head end to a skid lid of the coil support device 11.

Reference numeral 55 denotes a hydraulic cylinder, the tip of which is connected to the lever 53. Reference numeral 56 denotes a coil support device, which is provided on the receiving side arm portion 51a of the L-shaped frame 51 and is supported so as to be able to vertically intersect with a lifting skid on the carrying truck 61 on the loading side and to be vertically movable by a hydraulic cylinder or the like. It consists of a skid. Reference numeral 57 denotes a coil support surface, which is formed on the delivery-side arm portion 52b of the L-shaped frame 51 and has a fork-shaped flat shape that can vertically intersect with a lifting skid on the carry-out carriage 62 on the carry-out side.

7, after receiving the coil 60 in the vertical hole state, when the carriage 62 moves to the upstream end of the roller conveyor 63 and lowers the lifting skid, the coil 60 is delivered to the roller conveyor 63 in the vertical hole state, It is sent to the next process in the state of a vertical hole.

[0006]

In the conventional coil reversing device as described above, the L-shaped frame 5 is moved from the carrier 61 to the carrier.
If the stop of the carriage 61 is delayed when the coil 60 is transferred to the coil 1, the end face of the coil 60 may strongly collide with the coil supporting surface 57 of the L-shaped frame 51, and the coil 60 may be damaged. On the other hand, if the carriage 61 stops too early, the space between the coil 60 and the L-shaped frame 51 becomes wide, and the coil 60 slides down by its own weight with the inversion of the L-shaped frame 51, and the coil 60 60 may be damaged. For this reason, the carrier 61 has to be moved at a low speed so that the end face of the coil 60 and the coil supporting surface 57 of the L-shaped frame 51 are appropriately brought into contact with each other and stopped accurately at a predetermined position. It was bad.

As shown in (1), the hydraulic cylinder 18 is shortened, the L-shaped frame 10 is reversed to the original direction, and the above-described steps are repeated.

Therefore, according to such a coil reversing device, the delicate positioning operation of the coil 20a by the receiving-side conveying means (walking beam 2) becomes unnecessary, so that it is necessary to slow down the operation of the receiving-side conveying means. And work efficiency can be improved.

The coil 20a is connected to the coil supporting device 11
The soft movement of the coil supporting member 12 can be reliably performed by the slight movement at the slow speed, so that the coil can be prevented from being damaged due to collision, sliding down, or the like.

Further, since it can be directly connected in series or at right angles to the delivery side transport means (roller conveyor table 3), the configuration of the coil transport line is simplified, and various coil transport modes can be used. .

In this embodiment, the case where the coil 20a in the horizontal hole state is inverted to the coil 20b in the vertical hole state has been described, but the coil 20b in the vertical hole state is inverted to the coil 20b in the horizontal hole state. Can also.
