The running resistance of the adhesive tape is reduced for stable running and the bending of the adhesive tape is prevented.

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tube printer that prints on a resin tube for terminal number display, and more particularly to a tape guide adapter of a tube printer that is used when printing on an adhesive tape with release paper.
[0002]
[Prior art]
Can be printed on soft resin tubes and adhesive tape with release paper to create terminal number display tubes that can be placed on wires connected to relay terminal blocks of electrical equipment and terminal number display labels that are attached to relay terminal blocks. A tube printer configured as described above is known.
[0003]
This type of tube printer uses a platen roller and a thermal head to sandwich a tube or adhesive tape and an ink ribbon. The platen roller is driven by a motor to drive the tube, etc., and prints characters using the thermal head. In order to perform printing at the center position of the entire width of the tube or adhesive tape of various widths, a tube guide for positioning the tube or the like is provided before and after the platen roller.
[0004]
The tube guide in front of the platen roller (upstream side) is formed so that the two guide plates can be moved left and right symmetrically to enlarge or reduce the distance between them, and is provided immediately after the platen roller and at the tape discharge port. The two tube guides are of automatic centering type.
[0005]
The automatic centering tube guide is composed of two opposing lever-type guide plates and a spring, and is biased by the spring so that the tips of the two guide plates are closed. The two guide plates sandwich the tube and adhesive tape from the left and right sides, guide the tube and adhesive tape so that the center of the entire width is aligned with the center of the thermal head, and the tube guides are placed before and after the platen roller. Regardless of the thickness of the tube or the width of the adhesive tape, characters are printed at the center of the full width.
[0006]
[Problems to be solved by the invention]
Conventional tube printers are configured to adjust the distance between the manually adjustable tube guides according to the thickness of the tube to be used and the width of the adhesive tape with release paper. It may become large and cause printing defects. If the interval is too wide, the position of the tube or the like is shifted to the left and right, and the printing position varies.
[0007]
Since the resin tube is flexible, even if the width of the manually adjustable tube guide is adjusted to a certain extent, there is almost no printing failure, but the adhesive tape with release paper does not stretch in the width direction. Therefore, in the state where the adhesive tape is strongly sandwiched between the tube guides, poor running and poor printing often occur.
[0008]
In addition, thin tapes such as device label tapes with resin labels lined up on release paper may not be smoothly ejected due to frictional resistance, or may be bent to one side or the other when sandwiched from left and right by an automatic centering tube guide May rise up and the driving route may be disturbed left and right.
[0009]
Then, the technical subject which should be solved in order to send an adhesive tape stably arises, and this invention aims at solving the said subject.
[0010]
[Means for Solving the Problems]
The present invention is proposed to achieve the above object, and is a manually adjustable tube guide capable of adjusting the distance between a pair of guide plates in a feeding path of a tube formed on a printer unit or an adhesive tape with release paper. It is equipped with an automatic centering type tube guide that urges the two guide plates in the closing direction by a spring and sandwiches both ends of the tube or adhesive tape with release paper, and the terminal number etc. on the soft resin tube or adhesive tape with release paper Te tape guide adapter odor used for tube printer for printing characters,
The tape guide adapter forms a fixed guide plate for positioning the adhesive tape with release paper in the left-right direction, and an inclined guide portion with an ascending inclined surface on one side downstream of the fixed guide plate,
By attaching it to the adhesive path of the tube printer,
Wherein the fixed guide plates determine the lateral position of the adhesive tape with respect to the print head, the inclined guide portion by to rotate the posture of the adhesive tape in the traveling direction axis around, automatic posture inclined posture of the adhesive tape from the horizontal position The present invention provides a tape guide adapter for a tube printer configured to be guided to a centering tube guide and discharged in a vertical posture .
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, the configuration of the tube printer will be briefly described. FIG. 1 shows a part of a laptop tube printer 1 and shows a state in which a repellent head unit 3 of a printer unit 2 built in the rear part of the main body is repelled. A liquid crystal display 4 is disposed in front of the printer unit 2 (left side in FIG. 1), and a keyboard (not shown) is disposed in front of the liquid crystal display 4.
[0012]
A guide rail (not shown) is formed on the right side of the printer unit 2, and a resin tube for printing and an adhesive tape with release paper are inserted into the printer unit 2 along the guide rail from the right side of the main body. In the printer unit 2, two front and rear pinch rollers 7 and 8 pivotally attached to arms 5 and 6 that can be pivoted up and down are arranged. If the pinch roller opening / closing lever 9 at the rear of the printer unit 2 is rotated to the left in FIG. 1, the arms 5 and 6 are rotated upward, and if the roller opening / closing lever 9 is rotated to the right, the arms 5 and 6 are The pinch rollers 7 and 8 are lowered and pressed against the rollers disposed under the pinch rollers 7 and 8 so that the tube and the adhesive tape are sandwiched therebetween.
[0013]
On the downstream side (left side) of the pinch roller 8, an automatic centering type tube guide 10 constituted by a pair of opposing lever type guide plates is provided, and further, a cutter mechanism that does not appear in the drawing is incorporated in the downstream thereof. A further automatic centering tube guide (not shown) is provided immediately before the tube outlet.
[0014]
A thermal head 11 and a motor (not shown) are mounted in the head unit 3, and when the head unit 3 is pulled down and closed, the thermal head 11 is pressed against the platen roller directly below and an adhesive tape with a tube or release paper is attached. Pinch. Reference numeral 12 denotes an ink ribbon.
[0015]
FIG. 2 shows the configuration of the feeding mechanism of the printer unit 2, and the tube or adhesive tape travel path includes a manual tube guide 13, a driven roller 14, a platen roller 15, a feed roller 16, an automatic centering tube guide from the upstream side. 10, the platen roller 15 and the feed roller 16 are rotationally driven by a motor in the head unit 3 via a gear mechanism. At the time of printing, the two pinch rollers 7 and 8 are pressed against the driven roller 14 and the feed roller 16 to sandwich the tube or adhesive tape, and the thermal head 11 is pressed against the platen roller 15.
[0016]
When printing on a tube, the distance between the two guide plates on the left and right of the manual tube guide 13 is adjusted according to the thickness of the tube, but when printing on a thin adhesive tape, the left and right of the manual tube guide 13 are adjusted. If the tape guide adapter 17 is attached to the printer unit 2 as shown in FIG. 2 and FIG. 3 with a gap between the two guide plates, the adhesive tape can be fed accurately and stably.
[0017]
As shown in FIG. 4, the tape guide adapter 17 is formed in accordance with the shape of the guide rail portion so that it can be attached to the guide rail portion of the printer unit 3, and the driven roller 14, the platen roller 15, and the feed roller 16. Are opened, and fixed guide plates 21 and 22 are provided on the upstream side and the downstream side according to the width of the adhesive tape.
[0018]
Reference numeral 23 denotes a bridge portion straddling the driven roller 14 and the pinch roller 7, and the adhesive tape that has passed between the upstream side fixed guide plates 21 proceeds downstream through a slit 24 on the front surface of the bridge portion 23.
[0019]
The portion ahead of the downstream side fixed guide plate 22 is inserted under the automatic centering type tube guide 10 of the tube printer 1, and rises downstream on one side (right side toward the downstream side) of this portion. An inclined guide portion 25 is formed.
[0020]
Accordingly, the adhesive tape that has been printed and passed through the downstream fixed guide plate 22 rises on the right side and is sent between the automatic centering type tube guide 10. As shown in FIG. 6 is sandwiched between the automatic centering tube guide 10 in an oblique posture, passes between the cutter blades of the downstream cutter mechanism, and twisted 90 degrees counterclockwise from the horizontal posture toward the traveling direction as shown in FIG. Then, it is discharged through the automatic centering tube guide 26 on the discharge port side in a vertical posture.
[0021]
Conventionally, since the automatic centering type tube guides 10 and 26 using a spring sandwich both edges of the adhesive tape, the automatic centering type tube guides 10 and 26 and the adhesive tape are in point contact, resulting in a large frictional resistance and a thin thickness. Although the adhesive tape may not be smoothly fed downstream of the feed roller 16, the tape guide adapter 17 of the present invention sends the adhesive tape to the automatic centering tube guide 10 in a twisted state from a horizontal posture. Frictional resistance during running of the adhesive tape is low, and there is no occurrence of defective discharge of the adhesive tape or lateral movement.
[0022]
The present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modifications.
[0023]
【The invention's effect】
As described above, by attaching the tape guide adapter of the present invention to the tube printer, the adhesive tape is guided and sent to the fixed guide plate of the tape guide adapter. It is possible to prevent feeding failure and printing failure due to excessive frictional resistance. Also, since it is twisted from the horizontal position to the vertical position at the downstream of the feed roller and fed to the automatic centering type tube guide, the adhesive tape may be bent by the automatic centering type tube guide, or the discharge may be poor due to pinching pressure. In particular, it is effective in improving the running stability of a thin adhesive tape.
[0024]
In addition, by providing the inclined guide portion of the tape guide adapter on the back side when viewed from the printing operator side, the printing surface of the adhesive tape is discharged from the printer device in a vertical posture facing the printing operator side, There is also an effect that it is easy for the printing operator to visually check the printing state of the adhesive tape.
