Abstract

PROBLEM TO BE SOLVED: To provide a splicing device capable of easily splicing sheets of continuous paper having different widths. SOLUTION: In this continuous paper splicing device for splicing the paper 27 run out in a device having a continuous paper conveying mechanism, and the paper 26 to be set next, paper pressing mechanisms 2 and 4 respectively fixing one end in the width direction of the paper, and a pair of paper pressing mechanisms 3 and 5 adjustable corresponding to the paper width for fixing the other end of the paper are mounted respectively for a rear edge of the run-out paper and for a front edge of the paper to be set next, whereby the sheets of paper having the different widths can be fixed and connected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous paper splicing apparatus.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. The continuous paper splicing apparatus includes a paper table 21, paper guides 24 and 25 for adjusting the positions of the continuous papers 26 and 27 to be spliced in the paper width direction, and paper alignment in the paper width direction after the paper guides 24 and 25. Paper holding mechanisms 22 and 23 for fixing the paper holding mechanism.
2 and 23 are provided with only one set for simultaneously fixing continuous papers 26 and 27 having the same paper width. Therefore, in the prior art, the paper ends of the continuous papers 26 and 27 having the same paper width are provided. Splicing has been performed by fixing the sheets at the same time by a pair of sheet pressing mechanisms 22 and 23 and joining them by a splice tape 28 or the like.

[0003]

In the conventional splicing apparatus, after the continuous papers 26 and 27 to be spliced are aligned in the paper width direction, the paper pressing mechanism for fixing the continuous papers 26 and 27 having the same paper width. At the same time, there is a problem that when the continuous papers 26 and 27 have different paper widths, they cannot be fixed. An object of the present invention is to provide a splicing device that can easily splice even continuous paper having different widths.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paper holding mechanism for holding a rear end of a continuous sheet to be spliced, and a paper holding mechanism for holding a front end of a continuous sheet to be newly set and joined to the rear end of the continuous sheet. Are provided separately.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1, 2 and 3 are perspective views showing a splicing device according to an embodiment of the present invention. The splicing device includes a paper table 1, a paper holding mechanism 2, 3, 4,
5, paper guides 6, 7, 8, 9 and guide shafts 10, 1
It consists of 1,12,13.

The paper pressing mechanisms 2 to 5 have the same shape and include a paper pressing portion 14, a holder 15, a tension coil spring 16, spring support shafts 17, 18, and fulcrum shafts 19, 20.

The paper holding section 14 is provided rotatably with respect to the holder 15 via fulcrum shafts 19 and 20. The extension coil spring 16 is attached to a spring support shaft 17 attached to the sheet presser and a spring support shaft 18 attached to the holder, and is configured to press the sheet by the elastic force of the extension coil spring 16. A guide shaft 10 for moving the paper pressing mechanisms 3 and 5 in the width direction of the paper is provided below the paper table 1.
To 13 are attached.

With the above construction, the rear end of the paper 26 used up by the paper pressing mechanisms 3 and 5 which can move independently in the paper width direction and the paper 27 to be set next
Can be held down with the front end. With the rear end of the sheet 26 and the front end of the sheet 27 in contact with each other,
By sticking the splice tape 28 on the boundary line 7, sheets having different sheet widths can be easily spliced.

[0009]

According to the present invention, a paper pressing mechanism for pressing the rear end of a continuous sheet to be spliced and a paper pressing mechanism for pressing the front end of the continuous sheet to be newly set at the rear end of the continuous sheet and joined are separately provided. , The splicing operation can be easily performed even for continuous paper having different paper widths.
