Abstract

PURPOSE:To enable the accurate feed of an ink ribbon, by a method wherein a capstan is fabricated from a low hardness material while a pinch roller is excluded and a pass roller for regulating the wind-around amount of the ink ribbon to the capstan is provided. CONSTITUTION:A capstan 6 for positively feeding an ink ribbon 2 is fabricated from a low hardness material (pref., polyurethane rubber with Shore hardness A of about 20-30 deg.) and the ink ribbon 2 is wound-around the capstan 6 while a pinch roller is not used. The wound-around amount thereof is regulated so as to be sufficiently taken by the positional alteration of a pass roller 7 provided in the vicinity of the capstan 6. By this mechanism, the ink ribbon 2 is closely contacted with the outer periphery of the drive capstan 6 only by the tension of the ink ribbon 2 wound up by a spool 1 and transferred to a direction shown by an arrow A at a predetermined speed in a non-slip state by the drive capstan 6 to be wound up by the spool 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for an ink-filled ribbon tape used by being set in a printing device, for example.
C-1 Particularly, this invention relates to a ribbon tape winding device using a gab stan for transporting a ribbon tape in order to wind it in a predetermined amount.

FIG. 1 is a perspective view showing the main parts of a conventional ribbon tape winding device of this type, in which (1) is a spool for winding up the ribbon tape (2) published by Ink;
) is wound around the ribbon tape (2) and is used to transport the ribbon tape (2) in a predetermined direction, that is, in the direction of arrow (A) at a predetermined speed.
Press the ribbon tape (2) on the outer periphery of the drive capstan (3) and then attach the ribbon tape (2) to the outer periphery of the drive capstan (3).
This binge roller (4) is used to transport the material at a predetermined speed in the direction of arrow (A).
) or (C), and is configured to freely press the ribbon tape (2) onto the outer periphery of the drive capstan (3) with a predetermined pressure, thereby transporting or stopping the ribbon tape (2). (Wa) is” Ribbon tape with ink (2)
) is a drive shaft for rotationally driving the spool O) which is wound on the spool (1), and the drive shaft (5) is connected to the spool (1) by a friction joint (not shown), The difference in the rotational speed between the drive shaft (5) and the spool (1) due to variations in the winding diameter of the ribbon tape (2) is applied to this friction joint by There is.

Since the conventional ribbon tape winding device is subject to the precautions mentioned above, the pinch roller (4) that comes off when the ribbon tape (2) of any ink is not set in the printing device.
- is separated from the dynamic capstan (3), but r
f < Red the dynamic capstan (3) and attach one end to the spool (1
) to M・t,! , After setting the ribbon tape (2) in a single digit state, when the winding device is started, the pinch roller (4) + At the same time, the driving capstan (3) and the spool (1) are driven to rotate, and the ribbon tape (2) is transported at a predetermined speed in the direction of the arrow (A) by the driving capstan (3). At the same time, they are sequentially wound onto a spool (1).

In the conventional ribbon tape winding device with #i'j I7 as described above, the ribbon tape (2) with ink is
Every time you replace the drive capstan (
3) It is a drawn complex chick that separates from the chick, and it not only requires a mechanism with a large number of 8 key points (but also a driving capstan (
3) If any irregularities occur on the pressure contact surface between the pinch roller (A) and the pinch roller (A), the ribbon tape (2) will not be transferred accurately.
Moreover, the ribbon tape (2) has the disadvantage that it is likely to cause irregularities.

This invention 2 was made by paying attention to this point,
By making the driving capstan from a low-hardness material and increasing the adhesion 15C with the ink-covered ribbon tape (2) wrapped around it, the pinch roller that was conventionally attached to the driving capstan is omitted. The present invention aims to provide a ribbon tape winding device that achieves the following.

In other words, FIG. 2 shows an embodiment of the present invention.
(1,) $-]: A spool for winding up the inked ribbon tape (2), (5) is a spool for rotating the spool (1) for winding up the inked ribbon tape (2). On the drive shaft, the second drive shaft 7) (rl) and the spool (1) are connected to each other by a friction joint (not shown) K'), and the ribbon tape (1) wound on the spool (1) is
2) a drive shaft (5) according to the variation of the winding diameter;
This friction joint absorbs the difference in rotational speed with the spool (1). (6) is attached to the outside of the ribbon tape (2), and this ribbon tape (2) is
) in a predetermined direction, that is, in the direction of the arrow (A) at a predetermined speed. It is made of history material. (7) is installed near the lEI movement capstan (6), and this m<mυ river capstan (6) and an ink-covered ribbon tape wrapped around it. (2) Contact length with 7p4
Jji% i) Arrow (E) (1)
) is a pass roller that can move in the direction of

As mentioned above, the ribbon tape winding device of the present invention uses a low hardness material as the driving capstan (6). At the same time, the contact length of the inked ribbon tape (2) wound around the outer circumferential surface of the driving capstan (6) was sufficiently secured by the pass roller (force), so that the spool (1) The ribbon tape (2) is tightly attached to the outer periphery of the driving capstan (6) and is prevented from slipping when the tape (2) is wound up by the arrow (A). direction at a predetermined speed, and then sequentially wound onto the spool (1).
Depending on the material of the ribbon tape (2) with ink, the length of this ribbon tape (2) (7jl + length of contact with the moving capstan (6)) should be determined by passing the roller (kaniyotsu).
It's something to adjust.

As mentioned above, according to the present invention, the ink-covered ribbon tape (6) is used as a <-3 drive gear bustan (6) on a low hardness material, and is applied externally to the outer circumferential surface of the drive capstan (6). 2) σ−. )% Qjl 1
The pass roller (7) is designed to take sufficient thickness (・l), so there is no need for a structure with a structure similar to that of conventional pinch rollers, there are fewer Wl.l adjustment points, and it is cheaper , to provide an IJ bond tape winding device F'1.
It has the effect of making a difference.

Note 1. In the above-mentioned embodiment, the drive capstan (6) was made of low-grid material and converted to C-borium rubber.
・Although I mentioned one case when using it, it is not necessarily limited to 1!14, and if it is a soft material, n
``'< f (It goes without saying that any material such as rubber or soft synthetic resin will do.
