FIG. 1 is a schematic explanatory view showing an edge aligning device for a flexible sheet material according to an embodiment of the invention of claims 1 and 4, in which reference numeral 1 is a winding body. The holder 1 is rotationally driven by a motor M via a speed reduction mechanism R. Figure 6
As shown in FIG. 7 and FIG. 7, the winding body 1 includes a plurality of aggregates 1.
1 ... are arranged in a circle, and the central portions of the aggregates 11 are bent at one location so that the axial central portion 12 of the winding body 1 is sandwiched between the axial central portions 12. The diameter is slightly smaller than that of the side portion 13.

A flexible sheet material (cloth, cloth,
A sheet 2 of plastic, paper or the like is fed, and in the feeding process, the sheet-like material 2 is pulled to the center portion in the width direction by the hand-grip mechanism 3 so that the sheet-like material 2 is loosened in the center portion in the width direction. Granted. Further, the pair of left and right edge position correcting roller mechanisms 4 and 4 aligns the edges of the sheet-like material 2 on one end side and the other end side. Here, the hand-grip mechanism 3 needs to be arranged at a position in front of that including the place where the pair of left and right edge end position correcting roller mechanisms 4 and 4 are arranged.

In this embodiment, the hand-feeding mechanism 3 corrugates the sheet-like material 2 immediately after being unwound from the roll winding body 2A, and a sheet corrugated by the corrugating roller mechanism 8. The sheet-shaped product 2 including the corrugated portion 25 of the sheet-like product 2 is provided with a pair of left and right hand-rolling roller mechanisms 9 and 9 arranged corresponding to both sides of the sheet-shaped product 2 across the widthwise central portion 26.

As shown in FIG. 2, the corrugating roller mechanism 8 includes a first roller group 8A composed of a plurality of rollers 82 rotatable around a first shaft 81 and a second shaft parallel to the first shaft 81. 83
The second roller group 8B includes a plurality of rollers 84 that are rotatable around. The rollers 82 of the first roller group 8A and the rollers 84 of the second roller group 8B are arranged so as to wrap in the axial direction of the first shaft 81 and the second shaft 83, and A sheet-like material passage L is formed between the roller group 8A and the second roller group 8B.

Further, as shown in FIG. 4, the hand-rolling roller mechanism 9 includes a roller 92 rotatably mounted on a support 91 protruding from the fixed side and a fixed side rotatable about a horizontal axis 93. And a roller 95 rotatably attached to one end of a swing lever 94 supported by the sheet-like object 2 so that the sheet-like material 2 passes between the rollers 92 and 95. Further, the upper roller 95 is moved toward and away from the lower roller 92 by the operation of the cylinder 96 connected to the other end of the swing lever 94. And FIG.
Further, as indicated by an arrow 97 in FIG. 5, a feeding force in an inward direction that intersects the feeding direction 22 of the sheet-shaped material 2 can be applied to the sheet-shaped material 2.

Next, the edge position correcting roller mechanisms 4 and 4 operate based on the single edge position detection signal output from the edge detecting mechanisms 5 and 5 for detecting the edge position of the sheet-like material 2. The edge detection mechanism 5 detects the edge position immediately before the sheet 2 reaches the winding body 1, and the edge position correction roller mechanism 4 also detects the edge position immediately before the sheet 2 reaches the winding body 1. It is desirable that they are arranged so that the edges can be aligned. The edge position correcting roller mechanism 4 includes an operating position (position shown in FIG. 1) corresponding to the sheet-like object 2 fed with the edge position correcting roller mechanism 4 to the winding body 1 and the sheet-like object. It is connected to the delivery mechanism 6 that moves between the retreat position that does not correspond to the position 2 (the position outside the position shown in FIG. 1). The delivery mechanism 6 includes a screw shaft 61, a nut body 62 screwed to the screw shaft 61 and fixed to the edge position correcting roller mechanism 4 side, and a motor 63 for rotating the screw shaft 61. The edge detecting mechanism 5 and the edge position correcting roller mechanism 4 are connected by a connecting rod 51. Therefore, when the edge position correcting roller mechanism 4 moves between the operating position and the retracted position, the edge detecting mechanism 5 also moves integrally with the edge position correcting roller mechanism 4. The delivery mechanism 6 is controlled by the setting mechanism 64. That is, the setting mechanism 64 includes the winding body 1
In order to move the edge position correction roller mechanism 4 from the retracted position to the operating position at the beginning of feeding the sheet-shaped material 2 to the sheet feeding mechanism 6, the sheet feeding mechanism 6 is operated. When the edge 21 of the sheet-like object 2 is not detected, that is, when the edge-end detecting mechanism 5 detects the absence of the sheet-like object 2, the motor 63 of the feeding mechanism 6 is rotated in a predetermined direction to detect the edge-end detecting mechanism. Sheet material 2 by 5
It functions to move the edge position correction roller mechanism 4 to a position where the edge end 21 of is detected. By such an action of the setting mechanism 64, even when the sheet-like materials 2 having different widths are wound around the winding body 1, the edge-end detecting mechanism 5 and the edge-end position correcting roller mechanism 4 automatically take the sheet-like shape. The object 2 is moved to a position corresponding to the edge 21 and is set in an operable state. The starting end of the sheet-like material 2 is the winding body 1
The same applies when the mounting position is deviated from the reference position when mounting on the.

The edge detecting mechanism 5 is formed by attaching a photoelectric switch, a proximity switch, a mechanical contact switch or the like to the connecting rod 51. Edge position correction roller mechanism 4
May adopt the configuration shown in FIGS. 9 and 10, for example. In FIG. 9, the edge 21 of the sheet 2 passes through the gap between the drive roller 41 and the driven roller 42. The drive roller 41 is rotationally driven by the motor 43, and the driven roller 4
2 is attached to one end of a lever 45 rotatably supported by a shaft 44, and is vertically moved by a plunger 46 that operates the other end of the lever 45. Normally, the driven roller 42 is in an idle state, that is, pulled up from the driving roller 41 and separated from it, and is lowered only during operation and pressed against the driving roller 41 side. The drive roller 41 and the driven roller 42 rotate in the direction of rotation of the sheet-like material 2 (arrow 2 in FIG. 9 and FIG. 10).
2), and when the driven roller 42 is pressed toward the drive roller 41, the outside of the sheet-like material 2, that is, the axial direction X of the winding body 1 (see FIG. 1).
(See), it is possible to give an outward feed force along.

The roll-wound body 2A of the sheet-like material 2 is supported by the unwinding mechanism 7. The unwinding mechanism 7 is configured such that the rotary drive roll 71 provided therein imparts a rotational force to the roll winding body 2A to feed out the sheet-like material 2 of the roll winding body 2A. In FIG. 1, 72 is a drive motor for the rotary drive roll 71. The feeding speed of the sheet material 2 unrolled from the roll winding body 2A that is rotated by the rotation driving roll 71 of the unwinding mechanism 7 is synchronized with the feeding speed (winding speed) of the sheet material 2 to the winding body 1. It is possible to keep it, and the structure therefor is shown in FIG. That is, as shown in FIG. 1, the rotation speed of the drive motor M of the winding body 1 is detected by the detector 73, the detection signal is calculated by the control circuit 74, and the rotation speed control unit 75 of the rotation drive motor 72 is operated. Input both motors M,
72 is sequence-controlled. In this way, when the feeding speed of the sheet-like material 2 by the unwinding mechanism 7 is synchronized with the winding speed by the winding body 1, the edge alignment of the sheet-like material 2 is performed more reliably.

In the above, the sheet material 2 immediately after being unwound from the roll winding body 2A by the action of the unwinding mechanism 7.
Is deformed into a corrugated shape by the corrugating roller mechanism 8 to reduce its width, and then the corrugated portion 25 is centered in the width direction as indicated by an arrow 97 in FIGS. It is drawn to the department and the width is further reduced. Therefore, the width dimension of the sheet-like material 2 that has passed through the installation positions of the pair of left and right hand feed roller mechanisms 9 is shorter than the width dimension of the narrowest part of the sheet-like material 2 before being fed out from the roll winding body 2A. There is.

As described above, the sheet-like material 2 which is pulled by the corrugating roller mechanism 8 and the hand-rolling roller mechanism 9 and has a slack in the widthwise central portion thereof is corrected by the edge-end position correcting roller mechanisms 4 and 4. The slack is forcibly widened toward the outside along the axial direction X of the winding body 1, whereby edge alignment is performed. For this reason, even if the sheet-like material 2 has a non-uniform width dimension in each part in the longitudinal direction, it is possible to align the edges of the sheet-like material 2 at one end side and at the other end side with good accuracy.

Then, the sheet-like material 2 with the edges aligned
Is wound around the winding body 1 with its center portion in the width direction being slack. In this case, since the axial center portion 12 of the winding body 1 is made slightly smaller in diameter than the end portions 13 that sandwich the axial center portion 12, as shown in FIG. The central portion in the direction (that is, the slack 27) is wound around the axially central portion 12 of the winding body 1 having a smaller diameter, and the widthwise both end portions having no slack are larger than the axial central portion of the winding body 1 in diameter. It is wound around the large end portions 13, 13. Therefore,
It becomes difficult for the slack 27 to be pressed by the sheet-like material 2 wound around the slack 27, and the slack 27 is prevented from being pressed and wrinkled.

In this embodiment, although the hand-grip mechanism 3 is composed of the corrugating roller mechanism 8 and the hand-grip roller mechanism 9, only the corrugating roller mechanism 8 may be provided as the hand-grip mechanism 3, or the hand-grip roller mechanism. Only 9 may be provided, the former corresponds to the invention of claim 3 and the latter corresponds to the invention of claim 2. In addition, the axial center portion 12 of the winding body 1 sandwiches the axial center portion 12 and both ends 1
Those having a diameter smaller than 3, 13 correspond to the invention of claim 5.

[0027]

According to the first, second and third aspects of the present invention, the edge alignment is performed by expanding the flexible sheet-like material having a slackened central portion and a reduced width in the width direction. Therefore, even when the width dimension of the sheet-like material is not uniform in each portion in the longitudinal direction, the edge alignment can be reasonably and accurately performed on both end sides of the one end portion and the other end portion in the width direction. In particular, according to the third aspect of the invention, the width of the flexible sheet material can be reduced by deforming the flexible sheet material into a corrugated shape and slackening it without causing wrinkles.

According to the fourth aspect of the present invention, since the flexible sheet-like material is preliminarily hand-held by the corrugating roller mechanism, it is completely hand-held by the hand-rolling roller mechanism. It is possible to loosen an object without causing any wrinkles and reduce its width.

According to the fifth aspect of the present invention, the flexible sheet-like material is wound up without causing the slack imparted to the widthwise central portion of the flexible sheet-like material by the hand-grip mechanism to be wrinkled. It has the effect that it can be rolled up.
