Description

  The present invention relates to a printing apparatus for printing on a label without a mount.

  In recent years, as a printing apparatus used in a supermarket or the like, for example, a printing apparatus described in Patent Document 1 (Japanese Patent Laid-Open No. 8-244260) has been widely used.

  This printing device has a long label paper with a print area separated by perforations, a transport means for transporting the label paper, a print head for printing on the surface of the label paper, and a print head with the label paper sandwiched between them. The platen roller and a contact plate facing the surface of the label paper.

  The label paper is torn from the perforation by gripping the vicinity of the leading end of the printed first printing area and pressing it against the contact plate, and the leading printing area is separated as a label.

  However, in the printing apparatus as described above, it is assumed that the information to be printed falls within the interval between the perforations of the label sheet, and the length of the label cannot be changed according to the amount of information to be printed.

  From the viewpoint of ease of use of the label paper, a method of cutting the label paper according to the printed length is preferable. However, in that case, a problem easily occurs due to the adhesive of the label paper adhering to the cutting blade. Therefore, it is necessary to frequently maintain the cutting blade.

  An object of the present invention is to provide a printing apparatus that cuts label paper according to a printed length, and that suppresses adhesion of glue to a cutting blade.

  A printing apparatus according to a first aspect of the present invention is a printing apparatus that prints on a member to be printed and cuts the member to be printed with a cutting blade according to the printed length, and a label as a member to be printed. And a mark detection sensor and a control unit. The label is a label without a mount, and has a non-adhesive portion and an alignment mark on the adhesive surface side on the back side of the printing surface. The non-adhesive part and the alignment mark extend in the width direction orthogonal to the feed direction. Further, the non-adhesive portion and the alignment mark are present at predetermined intervals along the feed direction. The mark detection sensor detects the alignment mark. A control part controls operation | movement of a cutting blade so that a label may be cut | disconnected by a non-adhesive part, monitoring the detection signal of a mark detection sensor.

  In this printing apparatus, since the cutting blade is controlled so as to cut the non-adhesive portion, the adhesive of the adhesive portion does not adhere to the cutting blade, and the maintenance frequency of the cutting blade can be reduced.

  A printing apparatus according to a second aspect of the present invention is the printing apparatus according to the first aspect, wherein the color of the alignment mark is different from the color of the non-adhesive portion.

  In this printing apparatus, for example, by providing the mark detection sensor as a reflective photoelectric sensor immediately before the cutting blade on the traveling path of the label, only the adherend portion can be cut by the cutting blade.

  A printing apparatus according to a third aspect of the present invention is the printing apparatus according to the first aspect, in which an alignment mark is arranged on the adhesive portion of the label.

  In this printing device, the number of adhesive parts and non-adhesive parts per unit length can be increased compared to the type in which adhesive parts, non-adhesive parts, and marks are arranged side by side. Is done.

  A printing apparatus according to a fourth aspect of the present invention is the printing apparatus according to the first aspect, wherein the adhesive portion of the label is an alignment mark.

  In this printing apparatus, an increase in the number of manufacturing steps of the label is suppressed by substituting the adhesive portion as a mark.

  A printing apparatus according to a fifth aspect of the present invention is the printing apparatus according to the fourth aspect, wherein the alignment mark is formed of colored glue.

  In this printing apparatus, since it is not necessary to provide an alignment mark separately from the adhesive portion, an increase in the number of manufacturing steps of the label is suppressed.

  A printing apparatus according to a sixth aspect of the present invention is the printing apparatus according to the first aspect, and an alignment mark is arranged in the non-adhesive portion.

  In this printing apparatus, for example, in the method of coloring glue, since the management man-hour for preventing mixing between colorless glue and colored glue on the label maker side increases, the management cost may increase accordingly. is there. On the other hand, in the method using the non-adhesive portion as a mark, such management is not necessary, so that an increase in management cost can be suppressed.

  In the printing apparatus of the present invention, since the cutting blade is controlled so as to cut the non-adhesive part, the adhesive of the adhesive part does not adhere to the cutting blade, and the maintenance frequency of the cutting blade can be reduced.

1 is a schematic configuration diagram of a printing apparatus according to an embodiment of the present invention. The top view of the label paper seen from the adhesive surface side. Sectional drawing of the label detection sensor which identifies the adhesion part of a label paper of a printing apparatus which concerns on the modification D, a non-adhesion part, and them.

  Embodiments of the present invention will be described below with reference to the drawings. The following embodiments are specific examples of the present invention and do not limit the technical scope of the present invention.

(1) Schematic Configuration of Printing Device 1 FIG. 1 is a configuration diagram of a printing device 1 according to an embodiment of the present invention. In FIG. 1, the printing apparatus 1 includes a main body unit 20 and a control unit 40.

(1-1) Main unit 20
The main body 20 includes a label roll 21, a thermal head 23, a platen roller 25, a cutting blade 27, and a mark detection sensor 29.

  The label roll 21 is a member in which a label sheet 210 without a mount is wound in a cylindrical shape. In the label sheet 210, the front side is a printing surface and the back side is an adhesive surface. Therefore, a silicon coating process is applied to the print surface so that the adhesive on the adhesive surface side does not adhere to the print surface side when wound in a columnar shape. Further, an adhesive part 211 with glue and a non-adhesive part 212 without glue are formed on the adhesive surface side of the label paper 210 (see FIG. 2).

  FIG. 2 is a plan view of the label sheet 210 viewed from the adhesive surface side. In FIG. 2, the adhesive portion 211 and the non-adhesive portion 212 are formed on the label sheet 210 so as to cross in the width direction orthogonal to the longitudinal direction. The adhesive portions 211 and the non-adhesive portions 212 are alternately arranged on the label paper 210 along the longitudinal direction thereof.

  Further, the glue used for the adhesive portion 211 is colored in a color different from that of the non-adhesive portion 212. For this reason, if predetermined light is applied while moving the label paper 210 in the feeding direction, the adhesive portion 211 and the non-adhesive portion 212 have different reflectances and absorptances of the light. The amount of light reflected from each of the adhesive portions 212 is different.

  In the present embodiment, the colored glue of the adhesive portion 211 is used as an alignment mark, and the mark detection sensor 29 configured by a photoelectric sensor is opposed to the adhesive surface side of the label paper 210 as shown in FIG. The mark detection sensor 29 receives light reflected from each of the adhesive portion 211 and the non-adhesive portion 212. The mark detection sensor 29 can determine whether the detection target is the adhesive part 211 or the non-adhesive part 212 from the difference in the amount of received light.

  The thermal head 23 prints product information or the like on the printing surface of the strip-shaped label sheet 210 pulled out from the label roll 21. Print items include, for example, product names, additives, advertising texts, registration codes, barcodes, symbols, unit prices, contents, amount, amount, processing date, processing time, expiration date, best time, calories, product type, storage method , Store name, address, etc.

  The platen roller 25 is disposed so as to face the thermal head 23 with the label sheet 210 interposed therebetween. The thermal head 23 and the platen roller 25 sandwich the label paper 210 therebetween, and perform predetermined printing on the surface while feeding the label paper 210 by the rotational drive of the platen roller 25.

  The cutting blade 27 cuts the label paper 210 after printing at a predetermined position, and finishes the tip from the cut portion to a label. The operation of the cutting blade 27 is controlled by the control unit 40.

(1-2) Control unit 40
The control unit 40 includes a display unit 41 and an operation input unit 43. The control unit 40 is connected to the thermal head 23, the platen roller 25, the cutting blade 27, and the mark detection sensor 29, which are control targets. The content printed on the label surface by the thermal head 23 is determined based on print data such as a product number input from the operation input unit 43, print format data, and the like.

(2) Operation of Printing Apparatus 1 The control unit 40 rotates the platen roller 25 and sends out the label paper 210 from the label roll 21 while pulling it out. Further, the control unit 40 prints predetermined information determined based on input data from the operation input unit 43 on the surface of the label paper 210 by heating of the thermal head 23.

  Further, after the printing for one label is completed, the control unit 40 corresponds to one label while monitoring a predetermined number of adhesive portions 211 corresponding to one label via the mark detection sensor 29. When it is recognized that the predetermined number of adhesive portions 211 have moved, the moving blade 27a of the cutting blade 27 is moved to the fixed blade 27b side to cut the label paper 210.

  The distance between the mark detection sensor 29 and the moving blade 27a is fixed, and the tip of the moving blade 27a and the label paper 210 intersect when the mark detection sensor 29 finally detects the adhesive portion 211 in the movement of one label. The distance between the mark detection sensor 29 and the moving blade 27a is set so that the position always falls within the non-adhesive portion 212.

  Therefore, the cutting blade 27 can cut the label paper 210 so that both ends of one label always become the non-adhesive portion 212.

(3) Features In the printing apparatus 1, the adhesive portions 211 and the non-adhesive portions 212 are alternately arranged along the longitudinal direction on the adhesive surface side of the label paper 210 without the mount. The glue used for the adhesive part 211 is colored in a color different from that of the non-adhesive part 212. When the mark detection sensor 29 detects the number of adhesive portions 211 corresponding to one label, the control unit 40 operates the cutting blade 27 to cut the label paper 210 with the non-adhesive portion 212. Therefore, the glue of the adhesive portion 211 does not adhere to the cutting blade 27. As a result, the maintenance frequency of the cutting blade 27 can be reduced.

(4) Modification (4-1) Modification A
In the above embodiment, the colored adhesive is used as the adhesive of the adhesive part 211, so that the adhesive part 211 functions as an alignment mark. However, the present invention is not limited to this. For example, a system may be used in which blue and white lines are alternately placed in advance on the base paper of the label paper 210 and glue is applied only to the upper side of the blue line. In this modification A, the trouble of coloring the glue can be saved.

(4-2) Modification B
Further, even in the method in which the adhesive portion 211, the non-adhesive portion 212, and the blue line for alignment are alternately arranged in the feeding direction, the trouble of coloring the glue can be omitted, however, in this case, the adhesive portion per unit length When the number of the 211 and the non-adhesive part 212 is made equal to that in the above-described embodiment, it is necessary to pay attention to the fact that the areas of the adhesive part 211 and the non-adhesive part 212 are reduced.

(4-3) Modification C
In addition, since the adhesive portion 211 is not necessarily a mark, a system in which the non-adhesive portion 212 is a mark may be used. For example, by previously coloring the portion corresponding to the non-adhesive portion 212 of the base paper of the label paper 210 with blue or the like, the trouble of coloring the glue can be saved.

  In the method of coloring the glue, the management cost for preventing the mixing between the colorless glue and the colored glue on the label maker side increases. Therefore, the management cost may increase accordingly. On the other hand, in the method using the non-adhesive portion 212 as a mark, such management is not necessary, and an increase in management cost can be suppressed. Also, a mark that cannot be applied by the adhesive portion 211, for example, a mark for identifying with a minute protrusion (braille) can be applied.

(4-4) Modification D
The above-described embodiment and modification examples AC are based on the premise that a colored alignment mark is detected by a photoelectric sensor. However, the adhesive portion 211 is detected by detecting a difference in thickness between the adhesive portion 211 and the non-adhesive portion 212. And the non-adhesive portion 212 may be identified.

  3 is a cross-sectional view of the adhesive portion 211 and the non-adhesive portion 212 of the label sheet of the printing apparatus 1 according to Modification D, and a mark detection sensor for identifying them. As shown in FIG. 3, the adhesive portion 211 is closer to the mark detection sensor than the non-adhesive portion 212 by the thickness of the glue.

  Therefore, by adopting, for example, a photoelectric sensor as the mark detection sensor, the difference between the angle of light reflected from the adhesive portion 211 and the angle of light reflected from the non-adhesive portion 212 is The non-adhesive part 212 can be identified.

  In this modified example D, since it is not necessary to color any of the adhesive portion 211 and the non-adhesive portion 212, the cost of the label paper 210 can be reduced.

  As described above, according to the present invention, since the adhesion of glue to the cutting blade is suppressed, the present invention is not limited to the label printing apparatus, and is useful for an apparatus that cuts and uses a strip-shaped member having an adhesive surface. .
