Winding apparatus

Abstract

An arm for guiding paper fed along a paper feed path is swingably supported at its base end portion on one side of the winding core. The arm is provided with a free roll, on which the paper is guided to pass onto the winding core. At its free end portion, the arm has a roller rotatably mounted thereon which constitutes a body of rotation contacting with the paper roll so that with the winding core rotated and with the roller pressed against the paper roll the paper may be wound up into the paper roll on the rotating winding core without the occurrence of a paper winding wrinkle, whereby with a distance held constant at all times between the feed roll and the roller along a paper winding path, paper winding without such wrinkling can be achieved to yield a paper roll that is large in its maximum diameter.

Description

technical field [0001] The present invention relates to a winding device for winding paper to make roll paper. Background technique [0002] When printing paper such as continuous paper and winding it on a winding shaft (core) to make roll paper, if the paper is wound up strongly without applying tension to the paper to some extent, Then, the roll paper is in a softly wound state, and problems such as misalignment of the winding outer peripheral side with respect to the core side in the axial direction of the core or unraveling during conveyance of the roll paper occur. [0003] In particular, in the case of printing with an inkjet recording device, if the printed paper is not sufficiently dried and much moisture remains on the paper, the paper is soft and tends to become wrinkled just before it is wound up, and cannot be strong. Coiling, so prone to the aforementioned bad situation. [0004] Japanese Patent Application Laid-Open No. 05-077994 discloses a winding device th...

Problems solved by technology

[0008] In addition, since the arm 5 supporting the contact roller 6 is provided on the opposite side to the second free roller 2b with the winding core 7 as a boundary, the roll paper 8 wound up to the maximum diameter is unloaded and rolled to the downstream side. During the replacement, the contact roller 6 and the arm 5 become obstacles, making it difficult to replace the roll paper

[0009] In addition, it is not considered that the front and back of the paper 1 can be reversed for forward winding and reverse winding.
