Description

[Detailed Description of the Invention] The present invention relates to an up-coiler for winding a strip-shaped plate material such as a thin steel plate or an aluminum plate without using a reel or a mandrel.

The plate material is bent (plastically bent) to a predetermined radius by a bending roller, continuously fed onto a pair of support rollers, and wound into a coil shape on the support rollers. Although the plate materials are wound into a coil shape in this manner, friction occurs between the wound plate materials, and this friction may damage the surface of the plate materials. For this reason, the conventional practice has been to insert paper in the sanderch style and roll the paper together. However, the paper feeding section and the support rollers on which the board is wound are somewhat separated spatially, and the work of catching the paper between the board and the support roller at the beginning of winding up the board is done manually. The current situation is that this process is time consuming and dangerous as the sheet material is fed from the bending rollers.
The present invention has been made to avoid the above-mentioned problems, and provides a paper feeding device that has a simple structure and can safely feed paper.

Embodiments of the present invention will be described below based on the drawings.

Fig. 1 shows a cross-sectional view of the up coiler according to the present invention, where 1 is a machine frame, 2a and 2b are a pair of pinch rollers that grip a strip-shaped plate W moving from the direction of arrow A from above and below and continuously draw it in. , 3 are guides provided above and below the feeding path; 4, 5, and 6 are bending rollers provided on the downstream side of the feeding path from the pinch rollers 2a, 2b; 5 and 6 are rotationally driven by a drive device (not shown) to bend the plate material W upward and guide the plate material W to draw an arc around the horizontal axis. 7, 8 are bending rollers 4, 5, 6
A coil C formed by a plate material W that moves in an arc with a pair of support rollers located above the coil C.
support. Note that the upper pinch roller 2a that contacts the lower surface of the plate material W is configured to be able to change its position relative to the lower pinch roller 2b that is rotatably supported on the machine frame 1. Lower bending rollers 4, 5
is disposed on a rotating support 10 which is swingably supported at one end on the machine frame 1 by a shaft 9, and is configured to be able to change its position in the vertical direction with respect to the upper bending roller 6. . Stoppers 11 and 12 restrict the downward swinging position of the rotary support 10.
Reference numeral 13 denotes a pressing roller that comes into contact with the upper part of the coil C supported by the support rollers 7 and 8, and its intermediate portion is disposed at one end of a lever 15 that is pivotally supported on the machine frame 1 via a shaft 14. and the pressing roller 13
The position of is determined by a cylinder device 17 that retracts the stem 16 as the winding of the coil C progresses, thereby constantly maintaining the stability of the coil C being wound. 18 is a curved guide plate that guides the bent plate material W toward the support roller 8 side; 19 is a wrapping body for inserting paper, and is attached to the arm 15 at an intermediate position between the shaft 14 and the pressing roller 13. ing. Reference numerals 20 and 21 denote air supply pipes attached to the back surface of the guide plate 18, which are located above the pair of support rollers 7 and 8, and which inject air toward the lower side of the plate material feeding path. A spray nozzle 22 is provided along the length of the support rollers 7, 8 (see FIG. 3).

The lower bending roller 4 in FIG.
Position 5 indicates the work stop state, and the position changing device of the bending rollers 4 and 5 is changed by the cylinder device 26 via the link mechanism R consisting of the first, second, and third links 23, 24, and 25. The position is changed and fixed, and when the stem 27 of the cylinder device 26 is moved in the direction of arrow D, the third link 25 is moved in the direction of arrow F. It is pushed up through the shaft 9 and rotated upward about the shaft 9 to the position shown in FIG.

When performing winding work, the thickness of the plate material W is adjusted by rotating the rotating support 10 upward to a predetermined position to adjust the distance between the upper bending roller 6 and the lower bending rollers 4 and 5. The plate material W, which is set at intervals according to the material etc. and pulled in by the pinch rollers 2a and 2b, is bent to a predetermined radius by the bending rollers 4, 5 and 6 (plastic bending), and is continuously bent to the upper support rolls 7 and 8. When the plate material W is fed between the support rollers 7 and 8, the plate material W is wound around the coil C at an intermediate position between the support rollers 7 and 8.

At the initial stage of winding, the inserted sheet P of the winding body 19 is let out and hanging down as shown by the solid line in FIG.
The inserted sheet P, which had been hanging down due to the air flow jetted from the air blowing nozzle 22 just before being rolled up by the paper rollers 5 and 6, covers the support roller 7 as shown by the imaginary line in FIG. Then, by the cooperation of the pressing roller 13 and the support roller 7, the inserted sheet P is reliably fed out from the winding body 19. Specifically, the leading edge of the inserted paper P is caught between the end of the plate material W being rolled up and the support roller 7, and the pressing force of the plate material W against the support roller 7 side by the pressing roller 13 when the plate material W is rolled up and the pressure of the plate material W are reduced. Tension is applied to the insertion paper P between the winding body 19 due to the winding force, and as the coil C is wound up, the subsequent insertion paper P is sequentially paid out from the winding body 19, and the coil C is unrolled. It is inserted between the plate materials W.

As explained above, according to the present invention, the air blowing nozzles are arranged along the length direction of the support roller so that the leading edge of the inserted paper hanging down from the inserted paper wrapping body is brought to the support roller side on the curved guide plate. In the initial stage of winding, the inserted paper can be fed onto the support rollers without using any human hands, and the paper can be sandwiched between the plates in a sanderch-style manner safely and reliably without tedious work. .

Furthermore, the winding body of the insertion paper is rotated by an arm that is located above the curved guide plate and has a pressing roller attached to one end that contacts above the coil that is supported by the pair of support rollers. Since it is provided at an intermediate position between the center and the pressing roller, as the winding of the plate material progresses and the diameter of the coil increases, the arm supporting the pressing roller moves, and as a result, the wound body also moves closer to the supporting roller. The winding member moves away from the winding body to keep the distance between the contact point between the coil and the paper sheet and the winding body almost constant, so that a uniform tension is applied to the paper paper from the beginning of coil winding to the end of winding. Therefore, uniform feeding and uniform clamping of the plate material can be expected.
