Embodiment Construction

[0064] An embodiment of the present invention will be described below with reference to the accompanying drawings. This embodiment is an apparatus for manufacturing a flat wound body wound so that a plurality of strip-shaped sheet bodies are overlapped.

[0065] First, the structure of the wound body 1 manufactured by this embodiment is demonstrated with reference to FIGS. 1 and 2. FIG. FIG. 1( a ) is a schematic cross-sectional view showing the structure of a flat wound body 1 , and FIG. 1( b ) is an enlarged view of a bent portion located at an end in the longitudinal direction of the wound body 1 and its vicinity. Partial enlarged view of (a). Fig. 2(a) is a schematic side view showing the structure of the first sheet, the second sheet, and the separator sheet constituting the wound body 1, and Fig. 2(b) is a schematic plan view of the first sheet and the second sheet .

[0066] After winding the first sheet 4 and the second sheet 5 through two separator sheets 2 and 3 s...

Abstract

The object of this invention is to provide the winding apparatus which can improve the quality of the wound body obtained. The winding device includes a winding core (13) that winds the first sheet (4), the second sheet (5), and the separator sheets (2, 3) in an overlapping manner. In addition, the lengths of the non-laminated portions (4b) etc. on the first sheet (4) and the second sheet (5) are set in advance to have ample size, and each time the first sheet ( 4) and the second sheet (5) are wound on the winding core (13), the first sheet (4) and the second sheet (5) are detected by the first sensor (18) and the second sensor (19). ) on the winding starting end side (4c) of the lamination portion (4a) etc., while passing the first conveying jig (14A, 14B) and the second conveying jig (15A, 15B) to place the lamination portion (4a , 5a) at the winding starting end side ends (4c, 5c) are respectively aligned with the first reference position (K1) and the second reference position (K2), while winding the first sheet (4) and the second sheet body (5).

Description

technical field [0001] The present invention relates to a winding device for obtaining a roll by winding a strip-shaped sheet. Background technique [0002] There is a type in which a strip-shaped sheet is wound into a flat shape. [0003] In the flat wound body, the radius of curvature of the curved portions located at both ends in the longitudinal direction is very small. Therefore, there is a risk that the sheet may be damaged due to the bending stress acting on the bent portion due to the difference in thickness, hardness, etc. of the sheet to be wound. [0004] In this case, in recent years, there has been known a technique in which a laminated portion is intermittently formed along the length direction of the sheet in advance without forming a predetermined laminated portion on the surface of the sheeted body. It is wound so that the non-laminated portion of the laminated portion is positioned at the bent portion of the wound body (for example, refer to Patent Docume...
