DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine which is mounted outside a printer for printing predetermined information on a printing medium such as a label and winds the printing medium discharged from the printer around a branch pipe. The present invention relates to a branch pipe positioning device.

[0002]

2. Description of the Related Art Conventionally, a winding machine 2 as shown in FIG. 6 has been known. The winding machine 2 is fixed and positioned outside the printer (for example, a label printer) 6 by a mounting and fixing plate 4, and predetermined information is printed by the printer 6 and discharged in the discharge direction F. This is a device for winding a printing medium L such as a continuous body, and has a winding shaft 8 and a label pressing member 10. In addition,
Reference numerals 12, 14, and 16 denote first, second, and third guide rollers, respectively.

The take-up shaft 8 is cantilevered, and has one end (root side) for regulating one side end of the print medium L and winding the print medium L, for example, a paper pipe. A width regulating plate 18 for regulating also one side end of C is fixedly provided, and the other end is an open end. Note that the width of the branch pipe C is substantially the same as the width of the print medium L. The winding shaft 8 is rotated forward or backward by a driving source (not shown) (for example, a motor).

A holding member 10 is mounted from the open end side of the take-up shaft 8 and regulates and positions the other side end of the print medium L and the branch pipe C. It is provided detachably, and is fixed to the winding shaft 8 by a known method such as a spring (not shown).

[0005] In the following description, the "longitudinal direction W" refers to a direction substantially perpendicular to the discharge direction F of the print medium L discharged from the printer 6.

When the print medium L discharged from the printer 6 is wound by the winding machine 2, the branch pipe C is pushed in from the open end side of the winding shaft 8 and is fixed to the root side of the winding shaft 8. It is mounted so that one side end thereof abuts the width regulation plate 18 thus formed. Then, the print medium L is pulled out to the take-up shaft 8 via the first, second, and third guide rollers 12, 14, and 16, and wound around the branch pipe C. Further, the holding member 10 is mounted so as to contact the other side end of the branch pipe C from the open end side of the winding shaft 8, and the winding shaft 8 is rotated by a driving source (not shown) to rotate the branch pipe C. The print medium L is wound up.

Incidentally, in the printer 6, the central part of the print head (not shown) is actively used in recent years in consideration of the printing pressure balance and the thermal efficiency of a print head (for example, a thermal head) not shown. A method called "center distribution" has come to be used.

However, in the conventional winding machine 2, the positional relationship with the printer 6 including the longitudinal direction W is fixed and positioned by the mounting fixed plate 4, and one of the branch pipes C on which the print medium L is wound. Since the width regulating plate 18 for positioning the side end is fixed to the root side of the winding shaft 8, it is not suitable for center distribution. That is, if the conventional winding machine 2 is forcibly used for sorting the center, the printing medium L discharged from the central portion of the printer 6 can be used.
The print medium L is twisted to forcefully change the direction toward the branch pipe C contacted and positioned by the width regulating plate 18 fixed to the root side of the take-up shaft 8, and the other side of the print medium L There was a problem that the side end portion was rubbed by the pressing member 10 and the side end portion of the print medium L was damaged.

The pressing member 10 is separated from the width regulating plate 18 and positioned at the position of the other side end of the print medium L discharged from the central portion of the printer 6 so that the side end of the print medium L is not damaged. If the print medium L is wound up, the space between the presser member 10 and the width regulating plate 18 is widened, the branch pipe C is not stabilized, and the print medium L is wound up while meandering. Many occurred.

[0010]
