Embodiments of the present invention will be described below with reference to the drawings. In the following description, the left and right means the left and right in FIG.

FIGS. 1 to 3 show a bobbin for winding rolled material according to the present invention. The bobbin for winding is a bobbin main body (1) and a winding bobbin detachably attachable thereto. It is composed of a part width adjusting side plate (2) and a body diameter enlarging member (3).

The bobbin main body (1) is attached to the winder (14), and after a side plate (not shown) for preventing lateral deviation is fixed to the right end of the body (4), the length of the body (4) is fixed. It is possible to make a coil with an inner diameter equal to the outer diameter of the body (4) by winding a rolled material with a width equal to the height, and it is fixed to the shaft of the winder (14). Hollow shaft (7) and three vertical cross-section circles of the same shape that are attached to the hollow shaft (7) by a connecting member (8) with a gap between each other to form a cylindrical body (4). It has an arcuate body plate (5) and a circular fixed side plate (6) provided at the left end of the body portion (4).

The winding part width adjusting side plate (2) is a synthetic resin disc having a through hole (9) having a diameter equal to the outer diameter of the body part (4) and contacts the inside of the fixed side plate (6). Can be removably fitted.

The body diameter enlarging member (3) is made of metal,
Both the body wall (10) and the body wall (10) having an arcuate section with a vertical cross section having two longitudinally extending space retaining ribs (12) for retaining a predetermined distance from the body plate (5). A mounting portion (11) having a substantially vertical cross section which is provided on the edge so as to face each other and engages with the inside of both edges of the body plate (5) is provided. The horizontal length of the body wall (10) is
Side plate for adjusting the width of the winding section rather than the length of the body plate (5) in the left-right direction
It is shortened by the thickness of (2). Each body diameter enlarging member (3) is attachable to and detachable from each body plate (5), and three body diameter enlarging members (3) of the same shape are respectively attached to three body plates (5). By being fitted, a cylindrical winding drum portion (13) having a diameter larger than that of the drum portion (4) is formed.

The bobbin main body of the above winding bobbin
It became necessary to wind rolled material with a width narrower than the length of the body (4) of (1) into a coil with a coil inner diameter larger than the outer diameter of the body (4) of the bobbin body (1). In this case, the winding part width adjusting side plate (2) and the body diameter enlarging member (3) are manufactured as follows.

The thickness of the winding portion width adjusting side plate (2) is made equal to the difference between the length of the body portion (4) of the bobbin body (1) and the width of the rolled material to be wound. The length of the body diameter enlarging member (3) in the left-right direction is equal to the width of the rolled material to be wound. Waist wall (10)
The curvature of the space is set according to the target inner diameter of the coil, and the radial length of the spacing rib (12) is defined by the target inner diameter of the coil and the outer diameter of the body (4) of the bobbin body (1). The thickness of the body wall (10) is subtracted from half the difference. The circumferential length of the body wall (10) is slightly larger than the circumferential length of the body plate (5) of the bobbin body (1).

By attaching the winding width adjusting side plate (2) and the body diameter enlarging member (3) having the above dimensions to the bobbin body (1), the body (4) of the bobbin body (1) is attached. The rolled material having a width narrower than the length can be wound into a coil having a coil inner diameter larger than the outer diameter of the body portion (4) of the bobbin main body (1).

It takes about one month to newly manufacture the bobbin main body (1), but the side plate (2) for adjusting the width of the winding section and the member (3) for enlarging the body diameter are manufactured. It takes about one week to do so, and the production delivery time can be greatly shortened. In addition, the manufacturing cost can be reduced to about 1/10.

Since both the winding part width adjusting side plate (2) and the body diameter enlarging member (3) are removable, the winding part width adjusting side plate (2) and the body diameter enlarging member are enlarged. If both bobbin bodies (3) are removed and only the bobbin body (1) is used, rolled material with a width equal to the length of the body (4) of the bobbin body (1) ( It can be wound into a coil with a coil inner diameter equal to the outer diameter of 4), and only the winding width adjusting side plate (2) can be used to wind the body (4) of the bobbin body (1).
Rolled material with a width narrower than the length of the bobbin body (1) body (4)
It can also be wound into a coil having an inner diameter equal to the outer diameter of the coil.

[0018]

According to the bobbin for winding rolled material of the present invention, when the width of the material to be wound is smaller than the conventional one, a side plate for adjusting the width of the winding portion is newly manufactured and wound into a coil shape. If the inner diameter of the coil is to be made larger than before, it is only necessary to manufacture a new side plate for adjusting the width of the winding section, so the manufacturing cost is lower than when a new bobbin is manufactured, and The period can be shortened.
