Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding machine capable of automatically winding up an ultra-thin metal plate.

Conventionally, when winding an ultra-thin metal plate using a winding machine, a worker manually pulls out the tip of the ultra-thin metal plate to the winding drum, attaches the tip to the winding drum with adhesive tape, and then winds it up. The drum was rotated at high speed to perform winding.

However, such conventional means requires an extra worker, and there is a risk of cutting the ultra-thin metal plate by mistake when pulling it out to the winding drum, resulting in poor work efficiency. Further, winding is impossible in equipment where the winding material tip speed is high.

One type of conventional winding machine is a belt wrapper type winding machine, and the ability to automatically wind up the tip of the plate is the same as the object of the present invention. The winding start speed at the tip of the plate (currently the limit is about 300 or more) cannot be increased due to problems such as meandering and damage of the belt.

The present invention can be applied to special equipment that is characterized by an extremely high winding speed of the leading end of the material, except for the above-mentioned drawbacks of the belt wrapper type winder. Further, since the present invention has a simple structure, there is no fear of damage to the device and maintenance is easy.

Therefore, the gist of the present invention is to provide a winding drum that is movable and rotatable in a direction parallel to the direction of movement of an ultra-thin metal plate, a drive roll that rotates the winding drum by frictional force, and a drive roll that rotates the winding drum using frictional force. There is a patent that features an air nozzle that blows air in the same direction as the traveling direction of the plate.

Embodiments of the present invention will be described below with reference to the drawings.

The air nozzles (9α) are arranged along the drum (force), and the air nozzles (9α) are arranged at required intervals on the swinging frame (3).
The air blown out from α) is made to pass between the hole aυ bored in the guide plate mounting plate 00) and the guide plate (8) so that the air is blown in the direction of sending the ultra-thin metal plate (goods), and the swing An air nozzle (9b) is also provided above the frame (3) so that air can be sprayed in the direction in which the ultra-thin metal plate (goods) is sent through the hole a3 formed in the guide plate 03.

An arm α is pivotally attached to the upper part of the swinging frame (3), a presser roll Q5) that can come into contact with the upper surface of the winding drum (7) is pivotably attached to the tip of the arm (14), and the rear end of the arm (14) is pivoted. A spring Qe is disposed on the side of the drum for winding the presser roll O9 (a spring Qe biasing it toward the blade side).

A bearing (18) is mounted on a stand (17) erected on the frame (1).
) is disposed in the bearing 08, and a drive roll α that can come into contact with the winding drum (7) is arranged so as to be rotatable by a drive device (not shown), and above the drive roll a, An air nozzle (9c) is installed that blows air in the direction of sending the ultra-thin metal plate (goods) to the side of the ten-plane plate (a) that guides the ultra-thin metal plate (goods). In the figure (9d)
is the air nozzle, Qυ is the guide plate, (2 is the hole, (2J
is a pinch roll.

Next, the operation of the present invention will be explained.

The winding drum (7) is activated by operating the fluid pressure cylinder (4).
By bringing the winding drum into contact with the drive roll blade and rotating the drive roll α value by the drive device, the winding drum (force is applied by friction torque and rotated in the counterclockwise direction in Fig. 1), each air nozzle (9α) (9b) (9c) An ultra-thin metal plate (goods) of approximately 01/11II+ size that was pulled out from a manufacturing device (not shown) after blowing out combined air from (9d).
Sandwich it with a pinch roll (2 rolls) and send it to the guide plate (A) side.

The ultra-thin metal plate (goods) fed into the guide plate (to) is blown from the air nozzle (9c), passes smoothly through the guide plate (a) due to the pressure, and is taken up from the guide plate (a) to the winding drum. (It is sent to the blade side and is pressed against the winding drum (7) by the presser roll (151).
7). The tip side of the ultra-thin metal plate 0 is taken up by the re-drum (which rotates with force, and the air spray from the air nozzles (9h) (9c) passes smoothly through the guide plate (8) due to the pressure, and the air nozzle ('116) The spray from (9c) and (9d) is sent to the drive roll Ql and winding drum (force contact part side) by pressure, and is sent to the presser roll αω side while being held by the corresponding contact part. When the first spring winding is completed on the entry side of the presser roll a9 and the winding of the leading end of the material is completed, winding continues with the air nozzle closed.

As the ultra-thin metal plate (goods) wound on the winding drum (7) becomes thicker, the fluid pressure cylinder (4) operates and the swinging frame (3) moves sequentially from the α value side of the drive roll. The winding drum (7) is moved backward, and therefore the drive of the winding drum (7) is carried out via an extremely thin metal plate, but the pressure that presses the winding drum (7) against the drive roll α value is applied by the fluid pressure cylinder (4). Fine control of the winding tension is possible by adjusting the winding tension. ”
゛Also, due to the roll thickness of ultra-thin metal sheets (goods), presser/foot roll QSl
ft, but the presser roll Q is raised by the spring αQ.
5) is always pressed against the winding drum (7) with a substantially constant pressure, so that the extremely thin metal plate (goods) can be wound without any trouble. The presser roll a9 has the function of preventing meandering of the board during winding.

Furthermore, if the rotation speed of the drive roll 4 is synchronized with the feed speed of the ultra-thin metal plate 0, the outermost periphery of the ultra-thin metal plate (goods) is in contact with the drive roll α1, so that the roll becomes thicker. There is no need to change the speed of the drive.

The guide plate (8) in Fig. 2 laminarizes the air ejected from the air nozzle (9a) so that the winding drum (7) can move the air flow straight and without meandering the leading edge of the material.
It is possible to wrap it around.

In addition, if the height of the guide plate (8) is arranged as shown in Figure 2, the speed of the airflow can be made high at both ends of the plate and small at the center of the plate width, and the winding can be done at the tip of the material at the time. Meandering prevention function can be increased.

By the way, in this embodiment, when replacing the winding drum (7), the arm (14) is removed together with the presser roll αω, or the winding drum (force is supported on some kind of stand and the swinging frame ( 3) The work may be complicated and time consuming, such as having to remove it from the base.

On the required foundation, install a frame (251) for supporting the drum chock Qa, and install a frame (251) for supporting the drum chock (24) into the fitting groove (24).
A) is arranged so as to be inclined downward toward the drive roll <11 side, and the winding drum (7) is supported by the drum chock Q4.

A guide frame (5) is arranged at a predetermined position in front of the winding drum (7), and the guide frame can be slid toward the winding drum (7) by two cylinders of fluid pressure. A bracket (to) is pivotally attached to the tip of the sliding frame on the winding drum (7) side, and a bracket (to) is attached to the bracket (to) parallel to the winding drum (7). For pressing, a roll 0υ is installed, and for pressing, the roll Gυ is urged by a spring C31 to press the winding drum (blade surface) and prevent the winding drum (7) from shaking during the winding operation. Then, the presser roll α9 pivotally connected to the arm α is pressed against the winding drum (7) by the fluid E cylinder (c). In addition, in the figure (
) is a crane hook for replacing the idle drum,
Also, in the drawings, the same reference numerals as those shown in FIG. 1 indicate the same elements.

When winding an ultra-thin metal plate (goods), the sliding frame is pushed out to the winding drum (blade side) by a fluid pressure cylinder (toward), and the pressure is applied to the winding drum by a roll C3D. The presser roll 09 is also pressed against the winding drum (7) by the fluid pressure cylinder (7), and the work begins, but the ultra-thin metal plate
As the winding drum (7) becomes thicker, the groove CI! 0, the pressing roll Oυ is also retreated by the fluid pressure cylinder (up), and the presser roll α9 is also raised by the fluid pressure cylinder (up).

When replacing the winding drum (7), the arm αa is raised by the fluid pressure cylinder (c) and the presser roll 09 is replaced.
is released from the winding drum (7), and the sliding frame is pressed by the fluid pressure cylinder. Roll c3υ and presser roll a
