Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metal plate winding device for winding a metal strip such as a stainless steel plate into a metal plate coil.

(Prior art) Such a winding device for metal plates was developed in
It is publicly known from Publication No. 38072.

This conventional device consists of a winding drum with a horizontal axis that rotates in a fixed position and winds a metal strip around its outer periphery, a surrounding zone that can surround the outer periphery of the winding drum in a C shape, and a surrounding zone that can surround the outer periphery of the winding drum in a C shape. An endless guide belt having a return zone that returns around the outside, circumscribing the outer periphery of the winding drum from diagonally above and diagonally below through the guide belt, and making the encircling zone of the guide belt into a return zone. A pair of upper and lower turning rollers are vertically opposed to be turned, the upper turning roller is moved upward, and the lower turning roller is moved downward, respectively, to open the C-shaped surrounding zone of the guide belt into a horizontal U-shape. a displacement device, the guide belt and upper and lower deflection rollers, supporting the displacement device and approaching the winding drum in order to surround the outer periphery of the winding drum with the surrounding zone of the guide belt; A moving device for retracting to unenvelop the drum is provided, and a metal strip is supplied to one end of a C-shaped encircling section in which an encircling zone of a guide belt surrounds the outer periphery of the winding drum, and the metal strip is provided in the encircling zone. The strip is guided and wound around the outer periphery of the winding drum to perform winding.

In the above-mentioned conventional device, at the beginning of winding, a metal band plate enters from one end into a C-shaped surrounding area in which the surrounding area of the guide belt surrounds the outer periphery of the winding drum, and the tip of the metal band plate is placed at the other end of the surrounding area. When emerging from the winding drum, the leading end of the strip is advanced along the outer circumferential portion of the winding drum not surrounded by the guide belt and wound under the strip being drawn into one end of said section;
Guides having a triangular cross-section are attached to the upper and lower turning rollers that face each other vertically.

(Problem to be Solved by the Invention) In the above-mentioned guide, the tip of the metal strip that comes out from the other end of the enclosing section and tries to return straight due to elastic restoring force is not surrounded by a guide belt against the restoring force. Since the metal strip is forced to follow the outer periphery of the winding drum, the metal strip comes into strong frictional contact with the guide, causing damage to the metal strip. During winding of the metal strip, this conventional device moves the winding drum from beginning to end in the encircling zone of the guide belt.
There is a limit to the length of the metal strip that can be wound around the outer circumference of the winding drum to enclose it in a C shape, and the metal strip cannot be made into a large diameter coil. Since the metal strip is wound while being in frictional contact with the guide, the entire length of the metal strip that has become a coil is damaged.

(Means for Solving the Problems) Accordingly, the present invention provides that a metal band plate is inserted from one end into the C-shaped surrounding area of the guide belt surrounding the outer periphery of the winding drum, and the tip of the band plate is inserted into the C-shaped surrounding area of the guide belt. When it comes out from the other end of the encircling section, the tip of the strip is
The subsequent part of the metal strip that is drawn into one end of the enclosing section is guided along the outer circumferential part of the winding drum that is not surrounded by the guide belt, thereby preventing the metal strip from being scratched and thus preventing the winding. When the metal strip has been wrapped one or more turns around the outer circumference of the take-up drum, the take-up drum is unenclosed by the guide belt, the guide belt is evacuated, and the take-up drum itself winds the metal strip. The winding drum rotates in a fixed position and has a horizontal axis for winding the metal strip around its outer periphery, and the outer periphery of the winding drum is surrounded by a C shape. an endless guide belt having an enclosing zone capable of retrieval, and a return zone that returns around the outside of the enclosing zone; , a pair of vertically opposed upper and lower turning rollers that turn the surrounding zone of the guide belt into a return zone, moving the upper turning roller upward and the lower turning roller downward, respectively;

A pressing device for pressing and releasing the roller from the outer periphery, and a metal band at one end of the enclosing section in which the enclosing zone of the guide belt surrounds the outer periphery of the winding drum in a C shape, in front of the upper and lower turning rollers. The present invention is characterized by the provision of a pair of upper and lower movable guide rollers that sandwich and feed the plate from above and below, and a lifting device that raises and lowers the pair of upper and lower movable guide rollers as a unit.

(Embodiment) In the illustrated embodiment, 1 is a winding drum with a horizontal axis that rotates counterclockwise in a fixed position and winds the metal strip M around its outer periphery; 2 is an endless guide belt;
As shown in the figure, the winding drum 1 has a surrounding zone 2a that surrounds the outer periphery of the winding drum 1 in a C shape, and a return zone 2b that goes back around the outside of the surrounding zone. This guide belt 2 consists of a plurality of belts arranged in parallel, and includes two upper and lower movable rollers 4, 4 supported between a pair of U-shaped side frames 3, and a fixed roller 5 located between them, with a return zone 2b. A pair of vertically opposed upper and lower turning rollers 6 and 6 are supported between the U-shaped side frames 3 and can circumscribe the outer periphery of the winding drum 1 from diagonally above and below through the guide belt. Over the roller 7, the surrounding zone 2a turns into a return zone. The upper turning roller 6 can be moved upward by being pulled by a piston cylinder 8 whose bearing is attached to the U-shaped side frame, and the lower turning roller 7 is pulled by a piston cylinder 9 whose bearing is attached to the U-shaped side plate. When both cylinders 8, 9 simultaneously pull both the upper and lower turning rollers 6, 7, the surrounding zone of the guide belt 2 is deformed from a C-shape into a sideways U-shape and opens. The purpose of deforming the surrounding zone into a U-shape in this manner is to retract the U-shaped side frame to the right in FIG. 1 and release the winding drum from the guide belt, as will be described later.

In order to move the U-shaped side frame 3 left and right in Fig. 1,
The U-shaped side frame has a support spar 10, and this support spar 10 is sandwiched between a plurality of pairs of support rollers 11 from above and below, and the support rollers 11 are driven to rotate in forward and reverse directions, for example.

Surrounding zone 2a of the guide belt around the outer periphery of the winding drum
A pair of upper and lower stationary guide rollers 13 feed the metal strip M into the C-shaped surrounding area 12. In order to pass a metal strip between this pair of stationary guide rollers 13, the upper roller can be pulled up with a piston cylinder 13'. This fixed guide roller 13
A pair of upper and lower movable guide rollers 14 and 15 that move up and down as one unit are provided between the winding drum 1 and the winding drum 1 for relaying the thin metal plate coming out of the stationary guide roller. In order to raise and lower the movable guide rollers 14 and 15, a portal frame 18 is constructed of two vertical columns 16 and an upper beam 17 connecting the upper ends of both columns. A bearing support 19 is attached so as to be movable up and down along the movable guide roller 1.
4 and 15 are attached to this bearing support 19, and the square threaded shafts 20 hanging down from the upper beam 17 of the portal frame along the pillars 16 are screwed vertically into each bearing support 19, and the double square threaded shafts are screwed into each bearing support 19 in the vertical direction. By interlockingly rotating the bearings 20 in forward and reverse directions, both bearing supports 19 are raised and lowered. And movable guide rollers 14, 15
When in the lowest position, the height is the same as that of the stationary guide roller 13, as shown by the broken line in FIG.
In addition, 21 is driven to rotate in forward and reverse directions by a motor, etc., and is provided along the upper beam 17 in order to interlock the double-sided screw shaft 20, and 22 is the upper movable guide roller 1.
This is a piston cylinder attached to each bearing support 19 in order to pull up the bearing 4 and pass a thin metal plate between both rollers 14 and 15.

In this embodiment, in order to wind up the thin metal plate M together with the interleaving paper P, an interleaving paper roll R on which the interleaving paper is wound is installed above the machine body 23 that supports the winding drum 1, and A pair of guide plates 24 allows the interleaving paper to hang down in front of the exiting path of the thin metal plate. The above-mentioned portal frame 18 is erected on a movable platform 26 that can slide on the bed 25 of the aircraft body 23.
A horizontal square screw shaft 27, which is supported at one end and driven to rotate in forward and reverse directions, is threaded through the lower end of each column 16 of the portal frame. upper and lower movable guide rollers 14,
15 can be moved to a position close to the stationary guide roller 13 and a position close to the winding drum 1.

Further, the body 23 is provided with a pressing device 29 that can press the roller 28 against the outer periphery of the winding drum 1 and release the roller 28 from the outer periphery.

When winding is performed, the movable guide rollers 14 and 15 are brought close to the stationary guide roller 13 as shown in FIG. 2, and the slip sheet P is placed so that its lower end is below the path of the metal plate M. Then metal strip M
When the strip is sent out from the stationary guide roller 13, the tip of the strip pushes the lower end of the interleaving paper and enters between the upper and lower movable guide rollers 14 and 15, and the lower end of the interleaving paper is folded in two and released into the metal. The interleaving paper is fed out from the roll R while wrapping the tip of the band plate. In this way, the thin metal plate and the tip of the paper that come out between the upper and lower movable guide rollers 14 and 15 come into contact with the outer circumferential portion of the winding drum 1 that is not wrapped around the guide belt 2, and as the drum rotates in the counterclockwise direction, As shown in FIG. 3, from above the lower deflection roller 7 enters the enclosing zone 12 by the enclosing zone 2a of the guide belt.

When the tips of the thin metal plate and the interleaving paper enter the surrounding area, move the movable guide rollers 14 and 15 to a position close to the winding drum 1 using the horizontal square screw shaft 27, and move them together using the vertical square screw shaft 20. (Figure 1). As a result, the trailing portion of the thin metal sheet is drawn diagonally downward into the surrounding section 12 from between the upper and lower movable guide rollers 14 and 15, and from the surrounding section 12 it comes out under the upper turning roller 6 and the restoring force causes the metal sheet to extend straight. The tip of the band plate is connected to the movable guide rollers 14, 1.
5, the metal strip is brought into contact with the trailing part of the thin metal strip diagonally downwardly, and as shown in FIG. , the metal strip is wrapped around the outer periphery of the take-up drum for one or more turns. Once the metal strip is wrapped around the outer periphery of the winding drum, the upper and lower movable rollers 1 are raised.
4 and 15 are lowered.

When the tip of the metal strip is sufficiently wound up and there is no possibility of it returning due to elasticity, the upper turning roller 6 is pulled upward by the piston cylinder 8, and the lower turning roller 7 is pulled upward by the piston cylinder 8, as shown in FIG. cylinder 9
The guide belt 2a is pulled downward by the guide belts 2a and 2a to transform the surrounding zone 2a of the guide belt from a C-shape to a horizontal U-shape, and then the U-shaped side frame 3 is retracted as shown in FIG. 6 and the guide belt 2 is wound up. Lift the siege of Drum 1,
Instead, the pressing device 29 is advanced, and the roller 28 at its tip presses the wound layer of the metal strip wound on the outer periphery of the winding drum, and as the winding drum 1 rotates, the metal strip is wrapped around the outer periphery. Wind up. As the diameter of the wound layer of metal strip increases on the outer periphery of the winding drum, the pressing device 29 gradually retracts.

Note that when the U-shaped side frame 3 is retracted as shown in FIG.
The bearings of the movable rollers 4, 4, which had been applied with b, are moved by the piston cylinders 4', 4' to absorb the slack in the guide belt, and the guide belt is stretched in a straight line between the upper and lower turning rollers 6, 7. .

When the winding drum 1 has wound the entire length of the metal strip around its outer periphery, the interleaving paper is cut in the axial direction with a cutter (not shown), and the outer periphery of the coil is tied to prevent it from unwinding due to elasticity. Take it out from drum 1.

To wind up the next metal strip, move the upper and lower movable guide rollers 14 and 15 to a position close to the stationary guide roller 13, and while advancing the retracted U-shaped side frame 3 toward the winding drum 1. By retracting the movable rollers 4, 4 with the piston cylinders 4', 4', the surrounding zone 2a of the guide belt wraps the outer periphery of the winding drum in the horizontal U-shape shown in FIG. Down with cylinder 8,
The lower turning rollers 7 are respectively moved upward by the piston cylinder 9 to surround them in a C shape, and as mentioned above, the lower end of the interleaving paper is hung down below the path of the metal strip coming out from the stationary guide roller 13. You just need to restart the winding.

In this embodiment, upper and lower movable guide rollers 14 and 15 are used to wrap the tip of the metal band coming out between the stationary guide rollers 13 by folding the lower end of the paper in half.
can be moved to a position close to the stationary guide roller 13, but another pair of stationary guide rollers similar to the stationary guide roller 13 is provided at this position, and the movable guide rollers 14 and 15 are moved to a position close to the winding drum 1. It may be possible to only go up and down.

(Effects of the Invention) According to the present invention, a metal strip plate is supplied to one end of the C-shaped surrounding zone of the guide belt surrounding the outer periphery of the winding drum as in the conventional device, and the metal strip is supplied to one end of the surrounding section in which the surrounding zone of the guide belt The strip is guided and wound around the outer periphery of the winding drum to perform winding, and the leading end of the metal strip that comes out from the other end of the enclosing section and extends straight is connected to the guide belt by the trailing portion of the metal strip. Since it is wound along the outer periphery of the winding drum that is not wrapped in the metal band, it can prevent the metal band from being damaged. When the metal strip has wrapped one or more turns around the outer periphery of the winding drum, the C-shaped enclosing zone of the guide belt is opened into a horizontal U-shape and retreated, thereby unenveloping the winding drum. Since the winding is carried out by the rotation of the winding drum itself, the metal strip coil can be made into any diameter, and the metal strip will not be damaged at all.
