Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a roll paper processing device, and more particularly to a roll paper storage device ejected from a printer device.

[Prior art]

As shown in FIG. 2, the roll paper 14 is ejected from the printer device 12a of the AT controller 12 attached to the electric control panel 10. However, in the conventional printer device, the electric control panel 10 is allowed to hang down on the front floor surface.

[Problems to be solved by the device]

Not only does the roll paper drooping in this way have a poor appearance, but it also becomes dirty when the floor surface is wet and the printed data becomes unreadable. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a storage device that automatically rolls up roll paper sequentially ejected from a printer device and stores it. Another object of the present invention is to provide a printer device in which a printed roll paper is compactly housed in a storage device having a simple structure and which can be easily attached and detached to prevent the contamination of valuable data and to improve the appearance. There is.

[Means for Solving the Problems]

In order to achieve the above object, a roll paper accommodating device of the present invention comprises a cylindrical core as a winding center, a mandrel extending through the cylindrical core, and a spare roll wound around the core by a certain amount. It is composed of paper and a storage box which supports both ends of the mandrel and accommodates an assembly of a core, a mandrel and a spare roll paper.

[Action]

In the roll paper storage device configured as described above,
When the end of the roll paper ejected from the printer device is adhered to the end of the auxiliary roll paper, the wound auxiliary roll paper is loosened, so that the roll paper sequentially ejected from the printer device is automatically taken up. The first fixed amount of roll paper ejected from the printer device is attached to a cylindrical core instead of the preliminary roll paper and wound by a certain amount, and thus the core and the mandrel wound with the roll winding are fixed to the storage device. By doing so, it is possible to automatically wind the roll paper that is sequentially ejected.

【Example】

An embodiment will be described with reference to the drawings. As shown in FIG. 2, the storage device 16 of the present invention is provided below the roll paper outlet of the printer device 12a of the AT controller attached to the electric control panel 10, and the printer device 12a is provided. The roll paper 14 that is ejected is stored in the storage device 16. The storage device 16 includes a mandrel 18 that supports the core of the rolled roll paper, and a cylindrical core that serves as the core of the rolled roll paper 14.
20 and spare roll paper tightly wound around the core 20
14a and a storage box 22 for storing them. The mandrel 18 may be a long acrylic member provided with a notch 18a for installation as shown in FIG. The cylindrical core 20 may be made of cardboard and has an inner diameter that allows the mandrel 18 to be freely inserted therein, but both are fixed. An assembly in which the mandrel 18 is inserted into the core 20 is called a winding mandrel. The storage box 22 has a bottomed slot 22a for fixing the winding mandrel.
Is provided on both side surfaces, the bottom of the groove 22a is located substantially in the center of the side surface, and the notch for installation 18a of the mandrel 18 abuts on the bottom of the groove 22a. The storage box 22 may be made of acrylic, but is attached with a magnet plate so that it can be easily attached to and detached from the electric control panel 10. FIG. 1 shows a winding mandrel to be installed in the storage box 22. After a certain amount (100 to 200 cm) of the spare roll paper 14a is tightly wound around the core 20 of the winding mandrel, the winding mandrel is stored in the storage box 22.
When it is fixed in the groove 22a, the rolled preliminary roll paper 14a has a loosening motion. Along with this movement, the roll paper 14 adhered to the spare roll paper 14a is automatically wound up as it is successively ejected. If the winding amount of the spare roll paper 14a is less than 100 cm,
The amount of automatic winding of the roll paper 14 sequentially ejected is small, and conversely, even if the winding amount of the preliminary roll paper 14a is more than 200 cm, its effect does not increase. This critical significance has been clarified by the following experiment. That is, as shown in FIG. 2, the storage device 16 shown in FIG. 1 is arranged at a place where the roll paper 14 of the printer device 12a of the AT controller attached to the electric control panel 10 is ejected, and the core of the winding mandrel is inserted. The preliminary roll paper 14a is wound in advance by changing the winding length of the roll paper in the range of 50 to 250 cm, and the leading end of the roll paper 14 that is sequentially ejected is the preliminary roll paper.
Tape was attached to the end of 14a. In this way, the maximum length of the roll paper 14 successively ejected was wound around the core 20 of the winding mandrel was measured. The results are shown in Table 1. The width of the roll paper was 57 cm. From Table 1, typically, the initial winding length is 200c
If m is set and the end of the roll paper that is sequentially ejected is attached to the end, a roll paper of about 1 m is automatically wound. Therefore, the roll paper wound at this stage may be removed together with the winding mandrel, and the newly set winding mandrel may be attached. The roll paper ejected from the AT controller is 130 cm per week after 6 cycles of standard use. Therefore, if the rolled-up roll paper is cut out at each inspection, the punched roll paper is always contained in the storage box.

[Effect of device]

Since the present invention is configured as described above,
The following effects are achieved. The roll paper sequentially ejected from the printer device can be compactly housed in a storage device that has a simple structure and can be easily attached / detached, and the appearance of the printer device can be maintained well while preventing the contamination of valuable data.
