Description

[Detailed Description of the Invention] This invention relates to a coil tail reversing device that inverts the tail of the final winding portion of a coil in a coil receiver that receives a coil wound up by a coil box or a three-wheeled top-wound coiler.

In copper rolling work, the coil on the coil box or the coil on the coil receiver that receives the coil wound by the three-wheeled upper winding coiler is wound to the entrance side of the rolling machine by the transfer device, and the rolling process is performed again. When obtaining a strip of a given thickness, the tail of the last turn of the coil is kicked out onto the conveyor without being rolled up.

Since this becomes the introduction end when feeding into the next-stage feeding mechanism, it is necessary to provide a guide in the transfer device or manually bring the tail of the final winding portion of the coil to the desired position.

This invention provides a coil tail reversing device in which a simple guide is provided in the coil box or coil holder to mechanically reverse the tail of the final winding portion of the coil and bring it to the next stage feeding mechanism. That is.

This invention will be specifically explained below based on an example of copper elongation rolling.

In the figure, reference numeral 1 denotes a rolling mill housing in which work rollers 2, 2 are supported by backup rollers 3, 3, and a sheet passing guide 4 is provided on the introduction side thereof.

A coil box 5 is arranged on the entrance side of the guide 4, and the coil 6 introduced into the box is supported by three support rollers.

A pinch roller 7 is arranged at the rear of the coil box 5 facing the threading guide 4, and an arm 8 is pivotally supported on one side of the coil box 5.
A rod-shaped guide 9 is provided at the tip of the coil 6 to support the tail of the final winding portion of the coil 6 from below.

The arm 8 can be turned clockwise in FIG. 1 by rotation of a torque actuator 10 connected to its pivot portion.

A conventional three-wheeled upper coiler 11 is provided on the conveying side of the rolling mill housing 1, and includes upper and lower pairs of pinch rollers 12, 12 and bending rollers 13, 13.
13, and the above bending rollers 13, 13.1
Support rollers 14, 14 for the coil 6 are provided above the coil 3.

A hydraulic cylinder 16 is equipped with a coil receiving roll 15 on the upper surface of the three-wheel upper coiler 11 at the take-out side position of the coil 6.
A coil receiving device 18 is provided which can rotate up and down about the fulcrum pin 17 by the operation of
4, and the height can be adjusted so that the height can be made approximately the same.

In addition, 19 in the figure is a lifting truck that runs on a rail 20 provided above the three-wheeled coiler 11 and the coil receiving device 18, and the lifting truck 19 has a lifting cylinder 21 that moves up and down, Hook 2 inside the lower end of the hanging materials 22, 22
A coil lifting device 24 with 3 is provided.

Further, a coil conveying device 25 is provided on the rear side of the three-wheel upper-wound coiler 11, and this device 25 includes two drivable coil receiving rollers 26, 26 that receive and convey the coil 6.
is provided.

Further, there is an arm 27 pivotally supported on one side of the coil 6 above the rollers 26, 26, and at the tip of the arm 27 is a rod-shaped guide 28 that supports the tail of the final winding portion of the coil 6 from below. is provided, and the arm 27
can be turned clockwise in FIG. 1 by rotation of a torque actuator 29 connected to its pivot portion.

To explain the operation of the device configured as above,
After the coil box 5 supports the coil 6, when the rod-shaped guide 9 is turned clockwise in FIG. 1 by the torque actuator 10, one end of the coil 6 is attached to the guide 9
is rotated clockwise by the rollers, guided by the pinch rollers 7, guided to the rolling mill housing 1 via the threading guide 4,
Rolled by work rolls 2, 2, then pinch roller 1
2゜12 and penting roll 13, 13.1
3 and is wound on support rollers 14, 14 to form a coil 6.

Then, the coil 6 on the support rollers 14, 14 is sent out to the outside of the three-wheel upper coiler 11 by a kicking device (not shown), and supported on the support roller 14 and the coil receiving roll 15 of the coil receiving device 1B. In this case, when the center of gravity of the coil 6 moves to the outside of the support roller 14, the coil receiving roll 15 is immediately moved to a position where the coil 6 can be supported, and from this state, the hydraulic cylinder 16 is gradually contracted to remove the coil. The receiving roll 15 can be lowered and moved to the take-out position without causing any impact when taking out the coil 6.

When the coil 6 is sent out onto the coil receiving roll 15 and support roller 14 of the coil receiving device 15 in the above manner, the center hole of the coil 6 moves to the outside of the frame (not shown) of the three-wheel upper-wound coiler 11.

Then, the coil lifting device 24 of the lifting cart 1o provided above is lowered, and the hook 23 is used to lift it up.
The coil 6 is moved onto the coil conveyance device 25 and placed on the coil receiving rollers 26, 26 of the coil conveyance device 25.

However, the tail of the final winding portion of the coil 6 on the rollers 26, 26 remains on the three-wheel upper winding coiler 11 side.

At this time, the rod-shaped guide 2 is moved by the actuator 29.
8 around the outer circumference of the coil 6 in the clockwise direction in FIG.
It is rotated once and assumes the position of the introduction end for the next stage supply conveyance means.

As described above, according to this invention, a guide that supports the tail of the final winding portion of the coil from below is provided in the coil receiver that receives the coil wound up by the coil box or the three-wheeled coiler, and the guide is connected to the outer periphery of the coil. The guide is configured so that it can be rotated in the opposite direction to the winding of the coil, and the tail of the final winding portion of the coil is brought to the next stage feeding mechanism by the rotation of the guide. A practical effect can be obtained in that the tail of the coil can be easily put into a position where it can be used as the next introduction end.
