Abstract

PURPOSE:To facilitate the setting paper and the removal of roll paper by covering a detachable pipe with a longitudinal slit fitly on a core of a winding shaft with a paper fixing groove. CONSTITUTION:A pipe 6 provided with a slit 6a is covered fitly on a core of a winding shaft 1 provided with a paper fixing groove, and this pipe 6 is made free of rotation and pulling-out with the winding shaft 1. Paper 5 is inserted into the groove 2 of the winding shaft 1 through the slit 6a of the pipe 6, and the pipe 6 and the winding shaft 1 are twisted whereby the paper 5 is fixed to the winding shaft 1. Then, the paper 5 is wounded on the pipe 6 by rotation of the winding shaft 1. The paper rolled is removed from the winding shaft 1 without being deformed, together with the pipe 6, and then the pipe 6 is pulled out. Consequently, setting the paper 5 to the winding shaft 1 comes so sure and, what is more, the rolled paper 5 is also easily removable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a roll paper winding device, and particularly relates to paper mounting on a roll paper winding shaft.

[Conventional technology]

Figure 3 shows the winding shaft of a conventional roll paper winding device. In the figure, 1 is the core of the winding shaft, 2 is a groove for fixing the leading edge of the paper to this core, and 3 is the roll paper. 4 is a gear for transmitting power to the winding shaft, and 5 is a sheet of paper to be wound on the winding shaft.

The winding shaft of the conventional roll paper winding device is configured as described above, and when winding paper, the leading end 5a of the paper 5 is
is inserted into the groove 2 provided in the core 1 of the winding shaft, and in this state, the paper is wound around the core 1 of the winding shaft 2.3 times and fixed.

Next, when removing the rolled paper 5, one of the guides 3 is removed, and then the rolled paper 5 is held around its periphery and slid to be pulled out from the core 1 of the winding shaft.

[Problem to be solved by the invention]

Since the winding shaft of the conventional roll paper winding device is constructed as described above, it is easy for the leading end 5a of the roll paper 5 to slip out of the fixing groove 2 (also, the rolled paper When removing the paper 5, if the paper is tightly wound around the core 1 of the winding shaft, if you just hold the paper 5 around the edges and slide it, the part of the paper 5 close to the core 1 will not come off and the winding will be difficult. There were problems such as it losing its original shape.

This invention was made to solve the above-mentioned problems, and it is easy to attach the paper to the winding shaft, and the paper can be removed from the winding shaft without losing its shape. The purpose of the present invention is to obtain a roll paper winding device that can perform the following steps.

[Means to solve the problem]

The roll paper winding device according to the present invention has a double core of the winding shaft, the winding shaft guide is removable, and the winding shaft guide is used to remove the rolled paper. .

[Effect]

Since the winding shaft in this invention has a double core, the leading edge of the paper can be easily fixed by sandwiching it between the cores. Further, by making the winding shaft guide removable together with the outer core of the double core, the wound paper can be easily removed.

〔Example〕

FIG. 1 shows an embodiment of the present invention, and in the figure, 1.2.3.4.5 are exactly the same as the conventional device described above. Reference numeral 6 denotes a pipe-shaped core that is slidably placed over the core 1 of the winding shaft, and has a slit 6 & at one location in the vertical direction. Reference numeral 7 denotes a guide having a mounting hole having a diameter larger than the diameter of the core 1 of the winding shaft and smaller than the diameter of the pipe-shaped core 6.

In the winding shaft of the roll paper winding device configured as described above, when fixing the leading end 5a of the roll paper, the fixing groove 2 of the core 1 of the winding shaft and the slit 61 of the pipe-shaped core are aligned (the first 1 condition), roll into groove 2 & [I tip 5a
By inserting and twisting these two cores 1.6, fix the tip 5 to the winding shaft.

When removing the wound paper 5, as shown in FIG. 2, first remove the meandering prevention guide 3 and then slide the guide 7. Due to the relationship between the mounting hole diameter and the outer diameter of the core 1.6, the pipe-shaped core 6 slides off from the core 1 of the winding shaft together with the guide 7. At the same time, the rolled paper 5 can be removed from the core 1 of the winding shaft without losing its rolled shape. Then, by further removing the pipe-shaped core 6, removal from the winding shaft is completed while keeping the wound shape.

In the above embodiment, the guide 7 and the pipe-shaped core 6 are separate; however, the guide 7 and the pipe-shaped core 6 are integrated into the core 1 of the winding shaft.
It may also be attached to the paper, and this makes it easier to attach and remove the paper.

〔Effect of the invention〕

As described above, according to the present invention, the core of the winding shaft is made double and the guide is configured to be used for removing the paper, so it is possible to easily attach the paper and remove the rolled paper. effective.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is an explanatory view of its operation, and FIG. 3 is a perspective view showing a winding shaft of a conventional roll paper winding device. In the figure, 1 is the core of the winding shaft, 2 is a paper fixing groove, 3 is a guide, 4 is a gear, 5 is paper, 6 is a pipe-shaped core, 6m is a slit, and 7 is a guide. Note that the same reference numerals in the figures indicate the same or equivalent parts.
