Description

[Detailed Description of the Invention] <Industrial Application Field> When a metal plate such as a stainless thin steel plate is wound into a coil, it is wound together with interleaf paper to protect the surface of the plate. The present invention is directed to a metal coil rewinding device that automatically wraps and winds the leading edge of the interleaving paper that comes out together with the metal plate being rewound when the metal plate coil is rewound by a coil unwinding machine. This invention relates to a paper winding device.

<Prior art> In order to reuse the paper that comes out when unwinding a metal sheet coil without wasting it, conventionally, a coil unwinding machine rewinds the metal sheet as shown in Figure 7. At the beginning of the operation of the unwinding machine, a winding device M for interleaf paper is installed at the rear opposite to the forwarding roller B that sends out forward.
The metal plate S and the paper P are rewound to a length that allows the tip of the paper to be wound around the winding shaft of the winding device M, the metal plate is passed through the delivery roller B, the operation is interrupted, and the paper drips onto the floor. The worker holds the loose end of the interleaving paper P (shown by the solid line in the figure) in his hand, wraps it around the winding shaft of the winding device M as shown by the broken line and glues it, and then operates the unwinding machine and the winding device at the same time. , winding up the interleaf paper while unwinding the metal plate.

<Problems to be Solved by the Invention> The reason why the interleaf paper winding device M is installed at the rear on the opposite side from the delivery roller B is that the rewound metal is disposed between the unwinding machine and the delivery roller B. There is a complex guide mechanism to guide the tip of the plate to the delivery roller.
There is no space to install a winding device M for the interleaving paper, and the leading edge of the interleaving paper P that comes out together with the metal plate S is passed under the coil C installed in the unwinding machine and sent out. The metal plate coil is guided to the winding device M located opposite to the roller B, and is automatically wound by passing it across a lifting platform that lifts the metal plate coil to set it horizontally on the unwinding device. This is due to not being able to do so. Therefore, at the beginning of the operation, the operation was temporarily interrupted, and the worker manually wound the leading edge of the interleaving paper P around the core of the winding device M and glued it.

This significantly reduces the unwinding efficiency of the metal plate coil.

<Means for Solving the Problems> Therefore, the present invention provides a metal plate coil installed horizontally in an unwinding device, and a feeder attached to the unwinding device that forwards the metal plate of the metal plate coil to be rewound. In a space surrounded by a roller and a guide device that guides the tip of the metal plate to the delivery roller, a core that is longer than the width of the space and has an adhesive on the outer periphery is removably supported horizontally and driven to rotate. As a paper winding device in a metal plate coil rewinding device for winding a paper that is rewound together with a metal plate on the winding core during unwinding of the metal plate coil, the metal plate coil, On both sides of the space surrounded by the delivery roller and the guide device, there is a pair of opposing supporting devices that removably horizontally support each end of the winding core, and a winding device provided on one side of the support device. The present invention is characterized in that a motor for rotationally driving the core and a pair of elevating devices for raising and lowering the pair of support devices together are provided, and the pair of elevating devices are supported perpendicularly to the advancing and retracting device that moves back and forth.

<Example> In the illustrated example, 5 is a drive shaft of a rewinding device for horizontally installing and rewinding the metal plate coil C;
B is a delivery roller that pinches the metal plate M to be rewound from above and below and sends it out forward; 1 is a touch roller pivotally attached to one end of the arm 2; A is a roller that carries the metal plate coil C to be rewound into the rewinding device; This is a lifting platform for lifting and installing on a drive shaft, both of which are attached to a conventional rewinding device.

To unwind the metal plate coil C, as shown in FIG.
is passed through the inner circumference of the coil and installed horizontally on the unwinding device, then the lifting platform is lowered, and the arm 2 is swung by the piston cylinder 3 to press the touch roller 1 against the coil from above. Make sure the board does not come loose.

At the beginning of unwinding the coil, there are upper and lower guide arms 10 in front of the delivery rollers as guide devices for guiding the tip of the metal plate to be rewound between the upper and lower delivery rollers B.
There are 11. Since the structures of both guide arms 10 and 11 are symmetrical, the structure will be explained with reference to the upper guide arm 10.

The guide arm 10 has its end on the feed roller side pivoted to a horizontal support shaft 12, and its free end is vertically swingable about the support shaft 12, and is made of metal that can be rewound by an unwinding device. The lower surface is equipped with a guide surface that is wider than the maximum width of the plate coil. This guide surface is used to untie the metal plate coil C as described above, rotate the coil clockwise with the drive shaft 5 of the unwinding device as shown in FIG. To suppress the springback when it comes out,
It plays the role of advancing toward the sending roller B. Therefore, the guide surface may be a smooth flat plate, but in this embodiment, a fulcrum roller 14 coaxially attached to the support shaft 12 and a roller 15 at the free end of the arm 10 are used.
Several endless guide belts stretched in parallel between
It consists of 3. This guide belt 13 may be driven by contact with the emerging metal plate S, or may be actively driven in circulation. The guide belt 13 is supported by the lower surface of a receiving plate (not shown) attached between the guide arms 10 and rotates.

Support roller 14 for upper and lower guide arms 10 and 11
Bearings 12a that support each end of the support shaft 12 with attached
is screwed into an upright vertical tumble screw shaft 17 of the bearing lifting mechanism 16, and when the motor 16a rotates the screw shaft 17 in one direction, the upper guide arm 10
The bearings of the lower guide arm 11 move downward, and the bearings of the lower guide arm 11 move upward, approaching each other, and when rotated in the opposite direction, they move vertically away from each other. A downward piston 18 is connected to the middle of the upper guide arm 10, and an upward piston 18' is connected to the middle of the lower guide arm.
8' swings the guide arms 10, 11 to press the free ends of the two arms against the outer periphery of the metal plate coil C installed on the unwinding drive shaft 5, and to separate them from the outer periphery.

Furthermore, the bearings 12a, 12a of the upper and lower guide arms
are guide plates 19, 19 facing the delivery roller B, respectively.
is attached, and as mentioned above, when the tumble screw shaft 16 is rotated in one direction and both bearings are brought close together, the guide plates 19, 19 also come close, and the tip of the metal plate S of the coil C to be unwound is attached to the guide plate. It passes between 19 and 19 and is reliably guided to the circumscribed part of the delivery roller B.

As mentioned above, the metal coil C is installed horizontally on the rewinding device using the drive shaft 5, and after pressing the touch roller 1 against the coil from above, the upper and lower guide arms 10, 11
The bearings 12a, 12a are connected to the tumble screw shaft 17.
The guide plates 19, 19 are brought close to each other, and the free ends of the upper and lower guide arms 10, 11 are brought into contact with the outer periphery of the metal plate coil by the piston cylinders 18, 18'. As a result, the metal plate coil is unbound, and when the metal plate coil is rotated clockwise by the drive shaft 5 as shown in FIG. 3, the tip of the unwound metal plate S is guided to the guide surface by the belt 13 of the upper guide arm 10. After being moved diagonally downward, the feed roller B passes between the fulcrum rollers 14 and 14 of the upper and lower arms 10 and 11, passes between the guide plates 19 and 19
It bites and sends it forward. When the tip of the rewound metal plate S is caught by the delivery roller, the tumble screw shaft 17 is reversed, and the bearing 12a of the upper guide arm is moved upward, and the bearing 12a of the lower guide arm 11 is moved downward. The space between the fulcrum rollers 14 and 14 is opened.

When the metal plate coil is unwound in this manner, the interleaving paper wound together with the metal plate is also unwound and comes out of the coil.

The present invention provides a space 6 surrounded by the metal plate coil C, upper and lower guide arms 10, 11, and delivery roller B from the beginning of unwinding of the metal plate coil.
It is wound around the outer periphery of a winding core 20, such as a paper tube, which is horizontally supported in a detachable manner.

For this purpose, the core 20 is coated with adhesive on its outer periphery in order to wrap the tip of the interleaving paper, and its length is longer than the width of the space 6, that is, the width of the guide surfaces of the upper and lower guide arms 10, 11, and each The end portions are made to protrude outward on both sides of the space 6. A movable platform 24 of an advancing/retracting device 23 is mounted on a longitudinal rail 22 on a fixed frame 21 above the space 6 so as to be movable in the longitudinal direction. The width of this moving platform 24 is determined by the upper and lower guide plates 10,
11, on each side of which a vertical column 26 of a lifting device 25 and a vertical screw shaft 27 are attached downward in parallel. Then, the vertical screw shaft 27 is screwed into a pair of support plates 28, 28 which are engaged with each vertical column 26 at the dovetail engaging portions, and by rotating the vertical screw shaft 27 in the forward and reverse directions, each support plate 28 becomes a vertical column. Move up and down along the line.

In order to move the pair of support plates 28 and 28 up and down as one, both vertical screw shafts 2 are mounted on the moving table 24.
7 and 27 are provided, and are driven by a motor 29 capable of forward and reverse rotation.

The movable table 24 is screwed onto a square screw shaft 30 provided in the front-rear direction on the fixed frame 21, and a motor 31 that is attached to the fixed frame and capable of forward and reverse rotation is connected to the screw shaft 30.
It moves back and forth by rotating.

One of the support plates 28, 28 which move up and down integrally is provided with a rotation center 32 having an umbrella-shaped tip, and the other is provided with a drive unit 34 which also has an umbrella-shaped tip and is rotationally driven by a motor 33. Yes, rotation center 3
2 and the driving part 34 face each other with their umbrella-shaped tips, and the rotation center 32 can be extended or retracted toward the driving part 34.

The above-mentioned winding core 20 for winding the interleaving paper retracts the rotation center 32 before unwinding the metal plate coil, supports it horizontally between the rotation center and the umbrella-shaped tip of the drive part, and then rotates it. By protruding the center, it is supported horizontally by both umbrella-shaped tips.

After horizontally supporting the winding core in this way, the advancement/retraction device 23
The movable table 24 is moved on the fixed frame 22, and the pair of support plates 28, 28 are moved up and down by the vertical column 26 and vertical screw shaft 27 of the lifting device 25,
In Figure 3, the metal plate comes out diagonally downward from the metal plate coil with the metal plate on top and the interleaving paper on the bottom, so the winding core 20
Place it in a position where it comes down along the surface of the metal plate coil, and drive it to rotate with the motor 33 of the drive unit 34. When the tip of the interleaf paper P comes out, it is glued with the adhesive applied to the outer periphery and wound. take.

When the winding core 20 starts winding up the interleaf paper, the pair of support plates 28, 28 are operated by the advancement/retraction device 23 and the lifting/lowering device 25, and the vertical guide arm 10 shown in FIG.
and 11 to the center of the space 6 to the right away from the metal plate coil C, and thereafter the interleaving paper P is wound up by the winding core at this position. In FIG. 4, the tip of the metal plate S is now sent forward from the delivery roller B, so after this,
0 and 11 are separated vertically (arrow) as mentioned above,
Do as shown in Figure 5.

Figure 5 shows a state in which the metal plate coil C, which had an outer diameter indicated by the broken line, has been rewound to the outer diameter indicated by the solid line, and at the same time the winding core 20 has wound up a certain amount of the unwound interleaving paper. . Incidentally, FIG. 1 also shows a state in the middle of rewinding, similar to FIG. 5.

In this way, when the metal plate coil is unwound and the metal plate runs out and there is no more interleaving paper to be wound, the rotation of the winding core is stopped, the rotation center 32 is retracted, and the rotation center and drive unit are combined into an umbrella shape. The interleaving paper, which has been wound together with the core, is dropped from between the tips (Figure 6). As a result, the roll of interleaving paper is received by the lower guide arm 11, rolls on it, and is placed on the lifting platform A.
It can be carried out using a lifting platform.

In the above explanation, it is assumed that the metal plate coil C is rotated clockwise and unwound so that the metal plate and the paper come out diagonally downward from the top. When rewinding, the tip of the metal plate is guided to the feed roller B on the upper surface of the guide surface of the lower guide arm 11, and the interleaving paper comes out on top of the metal plate, so at the beginning of rewinding, the core 20 may be placed directly above the guide surface of the lower guide arm, and moved to the center of the space 6 when winding of the interleaving paper begins.

Furthermore, the movable platform 24 of the advancing/retracting device 23, which vertically supports the elevating device 25 consisting of a vertical column 26, a vertical screw shaft 27, etc., was moved back and forth on the fixed frame 21 above, but the elevating device was not perpendicular to the movable platform. The movable table may be set upright and moved back and forth on the floor.

<Effects of the Invention> In this invention, only the winding core with adhesive attached to its outer periphery passes horizontally through the space surrounded by the metal plate coil, the delivery roller, and the guide device, and both ends of the winding core are supported. a support device for leveling and rotating the support device; and a lifting device 3 for raising and lowering the support device.
0 and the advancement/retraction device 40 that moves back and forth are both placed outside the above space, so when operating these lifting devices and the advancement/retraction device to unwind the metal plate coil, the interleaving paper will come out along with the metal plate. Start winding the interleaving paper by moving the core to the next position and rotating it.
When winding begins, the sheet is moved to a wide position in the center of the space, and winding can be continued until the interleaving paper is used up.

This eliminates the inefficiency of the conventional rewinding process, in which the operator had to perform a short rewinding operation, interrupt the operation, and manually wind the unwound interleaving paper around the core of the winder. This invention can solve this problem and save labor.
