Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a mount guide device for a label printer.

Technical background of the invention and its problems In a label printer that prints by feeding a long backing paper with a large number of labels pasted one pitch at a time, meandering of the backing paper is not allowed in order to ensure the correct printing position on the label. Furthermore, the mounting position of the guide pieces that support both side edges of the mount must be adjusted according to the size of the mount.

Generally, as shown in Fig. 1, openings C are formed in a frame B that supports a mount A, and a pair of left and right L-shaped guide pieces D are attached to the frame B with screws E, with one end protruding into these openings C. A method is adopted in which the screw E is loosened, the guide piece D is slid according to the width of the mount A, and the screw E is tightened after positioning.

However, when adjusting the position of the guide piece D, a tool such as a screwdriver must be used, which has the disadvantage that the operation is cumbersome.

Purpose of the invention This invention was created in view of the above-mentioned points, and its purpose is to provide a mount guide device for a label printer that can adjust the position of the guide piece according to the mount with a single touch. .

Summary of the invention This invention press-fits multiple guide pieces made of soft material into a shaft-shaped guide piece that determines the path of the mount, and then slides the guide pieces in the axial direction of the guide according to the width of the mount. In addition, by forming a hard surface on the guide piece that connects with the mount, the decrease in wear resistance caused by soft material is improved, and furthermore, the support piece prevents the mount from coming off between the guide pieces. It is designed to prevent this.

Embodiment of the invention An embodiment of the invention will be explained based on FIGS. 2 to 5. Cylindrical mount mounting shaft 2 on frame 1
and leaf spring 3 are screwed together. A winding core 5 at the center of the mount 4 is fitted onto the mount mounting shaft 2.
Although the winding core 5 has an inner diameter larger than the outer diameter of the mounting shaft 2, it is held by the leaf spring 3 and held without play. A large number of labels 6 are attached to the mount 4.

Next, opposing side plates 7 are attached to the frame 1 via a plurality of guides 8. These guides 8 determine the route of the mount 4.
A horizontally elongated platen 9 and a label peeling body 10 are installed on the side plate 7, and a thermal head 11 that is elastically connected to the platen 9 is attached. Furthermore, the timing belt 1 is connected to the motor 12 fixed to the side plate 7 and one end of the platen 9.
One end of the mount winding shaft 14 attached to the frame 1 and one end of the platen 9 are connected by a spring belt 15.

A roller-shaped guide piece 16 made of a soft material such as rubber is press-fitted into one of the guides 8.
Hard surfaces 17 are formed on the inner surfaces of these guide pieces 16 by pasting metal disks. The hard surface may be formed by coating the guide piece 16 with a hard material. moreover,
A supporting piece 18 is provided at an intermediate portion between the guide pieces 16 and facing below the guide 8. This support piece 1
8 is positioned within a radius from the center of the guide piece 16 to the outer periphery.

In such a configuration, the thermal head 11
After printing on the label 6, the motor 12 is driven, and the platen 9 feeds the mount 4 in one pitch, and the mount 4 is moved by the mount winding shaft 14 in accordance with the amount of feed.
Wind up. Since the mount 4 is bent by the label peeling body 10, the label 6 is peeled off from the mount 4.

When this mount 4 is fed, the winding core 5 rotates due to the tension of the mount 4, but the winding core 5 does not continue to rotate due to inertia due to the braking action of the leaf spring 3.
This prevents the mount 4 from loosening and prevents the mount 4 from coming off the guide piece 16 downward. Even if the mount 4 becomes slack due to other causes, it is supported by the support pieces 18 at the position of the guide 8, so the mount 4 is still maintained in a state of being guided by the guide pieces 16. Therefore, meandering of the mount 4 can be reliably prevented. Moreover, although the guide piece 16 is made of a soft material, it has a hard surface 17 and is joined to the mount 4, so it has excellent wear resistance and can withstand long-term use.

If the size of the label 6 to be used changes, the mount 4
Of course, the width also changes. At this time, the interval between the guide pieces 19 can be adjusted by one-touch operation of sliding the guide pieces 16 along the guides 8. Since the guide piece 16 is press-fitted into the guide 8, it does not move in the axial direction under the lateral pressure of the mount 4, and can be fixed in any position using the high frictional force characteristic of soft materials. Therefore, there is no need to use a tool when adjusting the position of the guide piece 16.

Effects of the invention Since this invention is configured as described above, the opposing spacing of the guide pieces can be adjusted with one touch according to the width of the mount without using any tools. The decline in abrasion resistance caused by the material can be improved, and even if the mount becomes slack, the support piece can prevent the mount from coming off the guide piece, thus preventing meandering of the mount. This has effects such as being able to reliably prevent problems and accurately determining the printing position.
