Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for continuously winding up a strip of recording paper.

A conventional general recording paper winding device 10, as illustrated in FIG. 1 and FIG. The take-up reel 13 is rotated by the rotation of the take-up shaft 12, and the recording paper 15 is wound in from the guide roller 14.

In the above-mentioned apparatus, the winding start end of the recording paper 15 is locked by bending the tip diagonally and inserting it into the locking slit 17 of the winding drum 16 of the take-up reel 13.

For this reason, in the above-mentioned device, the operation for locking the recording paper 15 is complicated, and the shredded recording paper 15 cannot be easily removed from the take-up reel 13.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks, facilitate loading and unloading of recording paper, and downsize the winding device.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings of FIGS. 3 to 5.

It is composed of a recording paper winding device 201IJL of the present invention, a drive mechanism 21, a winding shaft 22, a winding drum 23 button, and a recording paper locking means 24.

The drive mechanism 21 is housed inside the winding drum 23 and is attached to the mounting plate 2.
5 and the gear 2 of this motor 26.
Reduction gear 28 as a power transmission mechanism 28 meshing with 7
It is composed of a t 28 b.

The mounting plate 25 is attached to the substrate 29 by a support 30, and the twisted substrate 29 is attached to the winding shaft 22. %- and reduction gear 28a
The frame 33 supports the shaft 31 of the
It is installed on.

The winding drum 23 is attached to the winding shaft 22, has an axial length smaller than the width of the recording paper 150, and has a flange 34 only at one end.

The recording paper locking means 24 is provided on the outer periphery of the winding drum 23 and locks the leading end of the recording paper 15.
The recording paper 15 wound around the flange 34 can be removed in a direction different from the position of the flange 34, and the one shown in FIGS. The ones shown in Figs.
3, and is formed by an elongated hole 24b that is opened at the end opposite to the flange 34.

The button and guide roller 35 is rotatably supported by a support shaft 36 with respect to the frame 33, and has flanges 37 at both ends thereof.

Now, to load the recording paper 15, the recording paper 15 is guided from the guide roller 35, and in the case of the embodiment using the leaf spring 24a, the recording paper 15 is aligned with the outer peripheral surface of the leaf spring 24a, and then folded inward and placed on the winding drum 24. In the case of an embodiment with a vertical elongated hole 24b, the button is pressed by bending the leading end of the recording paper 15 halfway and inserting it into the elongated hole 24b.

Next, when the motor 26 is started, the winding drum 23 is driven at a low speed by the drive mechanism 21, and the recording paper 15 is sequentially wound up.

In this case, although the winding drum 23 has a flange 34 only at one end, since the running direction of the recording paper 15 is regulated, the recording paper 15 is regularly wound around the winding drum 23.

All of the recording paper 15 is wound up on the winding drum 23, and the recording paper 15
In order to pull out the recording paper 15 from the winding drum 23, the recording paper 15 wound into a cylindrical shape may be grasped from both sides and pulled out in the direction of the open end of the side folding, which is different from the flange 34.

In this way, the recording paper 15 can be easily removed from the winding drum 23.

Moreover, at this time, the locking end at the beginning of the winding of the recording paper 15 easily slides off from the recording paper locking means 24, which is detachable in the direction of the open end.

The recording paper winding device 20 of the above embodiment is capable of handling the recording paper 1.
5, the recording paper width is 50 mm, and the recording paper feed speed is 25 VT.
The target is electrocardiogram recording paper of m/sec.

Therefore, the length of the recording paper winding device 200 and the winding drum 23 is 39 m.
The diameter of the drive motor 26 is approximately 100 rl)ffl, and the reduction ratio of the power transmission mechanism 28 is set to 1/6.

The present invention brings about the following effects.

1. The winding drum 23 has a flange 34 only at one end,
Since the other end is open, the rolled recording paper 15 can be easily pulled out from the open part without the flange 34.

2. Since the axial length of the winding drum 23 is set smaller than the width of the recording paper 15, the recording paper 15 is directly gripped on the inside and outside of the rolled recording paper 15 in the axial direction. It can be pulled out.

3. Since the recording paper locking means 24 locks the winding start end of the recording paper 15 in the winding direction and is in a state in which the winding start end can be removed in the direction of the open end on the side different from the flange 34, the recording paper 15 is removed, no unlocking operation is required.

4 Since the winding drum 23 in the embodiment is relatively thick, it is not only convenient to pull out the wound recording paper 15 by pulling it with your fingers, but also to provide a drive source in the internal space of the winding drum 23. Since the motor 26 button and power transmission mechanism 28 can be accommodated, the device can be further miniaturized.

5. When the recording paper locking means 24 is configured with an elongated hole 24b with one end open, the structure of the locking means is simplified, the frictional force when removing the residual recording paper 15 is small, and the extraction operation is easy. becomes.
