Description

  The present invention is suitable for applying glue to non-sticky labels printed and issued by a label printer so that the glue oozes out between the label and the mount and does not contaminate equipment or products, or cause troubles such as poor peeling. A method for issuing adhesive labels and a coater used therefor are provided.

  Label printers are used to print and issue labels for various purposes such as retail trade, shipping labels, and organization labels. FIG. 8 shows an example of a thermal label printer.

  The label printer 1 prints on an adhesive label 2 so that a device (feed device) 4 for feeding a label roll 3 or a long strip-like mount on which the printed label is attached. The apparatus (peeling apparatus) 6 which peels from 5 is provided.

  Further, the label printer 1 is equipped with a position sensor 7 for detecting notches, cut lines, marks printed on the mount 5, gaps between the labels 2 on the mount 5, and the like. It can be printed at various positions.

  Reference numeral 8 denotes a thermal print head. The label 2 having a surface made of heat-sensitive color paper (thermal paper) is sandwiched together with the platen roller 9, and the platen roller 9 rotates to convey the label 2 at the same time. 8 is printed on the label 2 by heating and scanning with a heat generation pattern corresponding to the image to be printed.

  The peeling device 6 conveys and guides the mount 5 to which the label 2 is attached while bending it at an acute angle via a peeling member such as a turning pin 10. When transported along, the label 2 attached to the surface of the mount 5 operates so as to be peeled off and separated from the mount 5 by its own waist strength (rigidity).

  The label 2 peeled off from the mount 5 is discharged from the discharge port 11. The label 2 discharged from the discharge port 11 is removed therefrom by the operator.

  If the label 2 discharged from the discharge port 11 remains without being removed by the operator and the subsequent label 2 is discharged, the labels stick to each other at the discharge port 11 and a paper jam occurs. Defects such as falling will occur.

  Therefore, an optical label sensor 12 for detecting whether or not the label 2 remains in the discharge port 11 is attached to the discharge port 11.

  In the label peeling issue mode in which the label 2 is peeled off from the mount 5 and issued one by one, when the optical label sensor 12 detects that the discharged label 2 is removed, the next label 2 is printed. Is supposed to start.

  Reference numeral 13 denotes a nip roller of the peeling device 6. The mount 5 after the label 2 is peeled off by the turning pin 10 is nipped and conveyed together with the platen roller 9 and is discharged from the mount discharge port 14.

  In addition to the label peeling issue mode in which the label 2 is peeled off from the mount 5 and issued one by one as described above, the label printer 1 continuously issues the label 2 with the label 2 attached to the mount 5 as described above. Can also be operated.

  Next, FIG. 9 shows a label printer for label without a mount, which is another known technique.

  The label without a mount is popular as an environmentally friendly label by removing the mount from the label. In other words, compared to a label with a backing paper (release paper), it can be rolled longer because it is thinned when rolled, improving production efficiency, reducing the number of label roll replacements for the user, and not using a backing paper. This eliminates the need for disposal costs and contributes to reducing the environmental burden, and has the advantage of reducing energy consumption.

  A general label without a mount is label-printed on the surface of a continuous substrate of paper or plastic film, and glue (adhesive) is applied to the entire surface of the back surface and wound into a roll. The label surface is coated with a release agent such as silicon so that the glue does not adhere to the label surface.

  A general label printer 20 for non-mounting label is provided with a cutter device 21 for cutting out a sheet-like label. As the cutter device, a simple cutter such as a razor blade or a motor (see FIG. A movable blade 22 driven by power such as (not shown) having a structure in which a tape-shaped label 24 is sandwiched between the movable blade 22 and a fixed blade 23 (guillotine type, rotary type, circle type cutter, etc.) is used. It has been. The cutter device is provided with an optical sensor 25 having a structure substantially similar to that of the optical label sensor 12 described above, and detects labels such as marks and cutouts on the label 24 to detect the label 24. The cutting position is determined.

  The label printer 1 and the label printer 20 for non-mounting label described above are each designed exclusively, but there are also those in which the peeling device 6 and the cutter device 21 can be replaced as a unit.

  By the way, in the above-described prior art, the label with glue applied to the back surface in advance is between the label and the mount when the storage condition is bad (in the case of a label without a mount, between the upper layer label and the lower layer label). The glue oozes out, contaminates equipment and products, and causes troubles such as peeling failure.

  In addition, in a label printer with a cutter device, the cutting blade abuts on the back side of the label with glue, and cuts, so that the glue adheres to the blade part and the glue sticks out and stringing easily occurs during repeated cutting, This could cause problems such as paper jams (paper jams).

  Therefore, in order to prevent troubles, maintenance work such as periodic cleaning of the blades is required, and if trouble occurs during label cutting, the label printer is temporarily stopped, etc. , Had lost productivity.

  The present invention has been made in view of the above-mentioned problems of the prior art, and paying attention to the fact that the problem can be solved by printing and issuing a label and then applying the glue, no glue is applied. It is an object of the present invention to provide a method for issuing an adhesive label suitable for use in applying glue to the back surface of a printed label after the label is printed from a label printer, and a coater used for carrying out the method.

  That is, in order to solve the above-mentioned problem, the means adopted by the first invention is to set a non-adhesive label continuous body formed with a cut line on a label printer that operates in the peeling issue mode and print on the label. In the method of issuing an adhesive label in which the coater is installed so that the insertion port is continuous with the label issuing port of the printer, and the coater operates in conjunction with the operation of the label printer, the coater An insertion port for inserting a label without glue, a discharge port for discharging a label coated with glue, an inlet side sensor for detecting the presence / absence of a label at the insertion port, and detecting the presence / absence of a label at the discharge port Provided on the outlet side sensor and the insertion port side, and starts to operate when the inlet side sensor detects the label. A holding mechanism for holding the label, and the transport mechanism and the glue application mechanism caused by the detection state of the inlet side sensor are performed only when the outlet side sensor detects a no label state. This is a method for issuing an adhesive label.

  In this case, the label printer may be operated only when the outlet side sensor detects a no label state.

  Also, an insertion port for inserting a label without glue on the back surface, a discharge port for discharging a label coated with glue, an inlet side sensor for detecting the presence or absence of a label at the insertion port, and the presence or absence of a label at the discharge port An outlet side sensor that detects the presence of the adhesive, a feeding mechanism that starts operation when the inlet side sensor detects a label, and a glue application mechanism that are provided on the outlet side, holding a label with glue applied And a holding mechanism that performs the operations of the transport mechanism and the glue application mechanism due to the detection state of the inlet side sensor only when the outlet side sensor detects a no label state. A coater is also provided.

  According to the first invention, since the coater operates by detecting the label discharged from the label printer, it is only necessary to provide a cut line (perforation) on the label without providing a cutter device in the label printer. When the transport mechanism inside the coater is operated, the label at the tip is torn off by a tear line, and it can be issued from the discharge port side as an adhesive label which is transported in the coater and coated with glue.

  In particular, it is more preferable to cause the label printer to operate only when the exit side sensor detects a no-label state, because it can prevent the occurrence of paper jam.

  According to the second aspect of the invention, when a label printed with a printer and having no glue on the back side is inserted from the insertion port of the coater, the transport mechanism and the glue application mechanism start operating, and the glue is applied to the back side of the label. Then, it is discharged to the holding mechanism on the discharge port side.

  Therefore, an adhesive label can be issued on demand, and in particular, since the outlet side sensor works in preference to the inlet side sensor, it is possible to eliminate the risk of clogging at the discharge port even if there is no mount.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the component same as the prior art mentioned above, and the description is abbreviate | omitted.

  FIG. 1 shows a first embodiment of the present invention. An insertion port 41 of a coater 30 described later is adjacent to a label issuing port of a label printer 1 on which a non-adhesive label 31 is set. The coater 30 is operated in conjunction with the operation of the label printer 1.

  The label printer 1 is operated in the same label peeling issue mode as described in the prior art. As the label 31, a label on which the paste is not applied as shown in FIGS. 3 and 4 is used. The label 31 is divided into small label pieces 32 by a cut line (perforation) 32.

  FIG. 2 shows a second embodiment of the present invention, in which the insertion port 41 of the coater 30 is adjacent to the label issuing port of the label printer 20 on which the non-adhesive label 31 is set. The coater 30 is installed and operated in conjunction with the operation of the label printer 20.

  The label printer 20 operates the cutter device 21 which is the same as described in the prior art. As the label 31, a label on which the paste is not applied is used as shown in FIGS. 3 and 5.

  In the second embodiment, the label printer 20 is operated only when the outlet side sensor of the coater 30 detects the no label state, that is, the label printer is connected via the outlet side sensor 44 of the coater 30. The coater 30 and the label printer 20 are connected by a cable 55 in order to operate the printer 20 in the label peeling issue mode.

  The main difference between the first embodiment and the second embodiment is the method of cutting the label 31. In the former, a cut line 34 is provided on the label, and the transport force of the label printer 1 and the coater 30 is used. On the other hand, in the latter, the label pieces 32 cut by the cutter device 21 after the label printing is issued are sequentially coated by the coater 30.

  The appearance of the label 31 is as shown in FIG. 3, the one for the first embodiment (FIG. 1) is shown in FIG. 4, and the one for the second embodiment (FIG. 2) is shown in FIG. . In the figure, 33 is a mark for label position detection.

  Reference numeral 40 denotes a case constituting the coater 30. An insertion port 41 for inserting a label with no glue on the back surface is formed on one side of the case 40, and a discharge port 42 for discharging a label coated with glue is formed on the other side of the case 40. Yes.

  The case 40 is provided with an inlet side sensor 43 that detects the presence or absence of a label at the insertion port 41 and an outlet side sensor 44 that detects the presence or absence of a label at the discharge port 42.

  Reference numerals 45 and 46 denote transport mechanisms provided on the insertion port 41 side in the case 40. The transport mechanisms 45 and 46 are composed of a roller or a belt whose surface is coated with a silicon resin or a fluorine resin so that a hot-melt adhesive 48 described later does not adhere. Moreover, the non-adhesion state is maintained so that it may not get wet with an adhesive when it contacts with the hot-melt adhesive 48 by cooling with the cooling mechanisms 51 and 52 mentioned later.

  Reference numeral 47 denotes an application roller as a glue application mechanism, which is rotatably supported while being partially immersed in the hot melt adhesive.

  The transport mechanisms 45 and 46 and the glue application mechanism 47 perform the transport and glue application operations only when the outlet side sensor 44 detects a label-free state and the inlet-side sensor 43 detects a label state. Is set to do.

  48 is a hot melt pressure-sensitive adhesive, which has a high viscosity at room temperature (room temperature) and cannot be applied to printing paper. However, when heated, the viscosity decreases and fluidity is exhibited, so that it can be applied to printing paper without adding an organic solvent. It is a type of pressure-sensitive adhesive, and when it is cooled to room temperature again, it loses its fluidity and remains tacky and is already widely used.

  A holding mechanism 54 is provided outside the discharge port 42 of the case 40 so as to hold a label to which glue has been applied.

  49 is a heater for keeping the viscosity of the hot melt adhesive constant, and 50 is a temperature control device. Reference numerals 51 and 52 denote cooling mechanisms including air cooling fans and exhaust ports that prevent the transport mechanisms 45 and 46 and the hot melt adhesive 48 from overheating.

  The present embodiment has the above-described configuration, and the coater 30 operates by detecting the continuous label 31 discharged from the label printer 1, so that the label printer 1 can be used without providing a cutter device. Since the cut line 34 is provided at 31, the label printer 1 is stopped when the transport mechanisms 45 and 46 inside the coater 30 are operated. Therefore, the label piece 32 at the leading end is torn off by the cut line 34, and the coater 30. It can be issued from the outlet 42 side as an adhesive label that is conveyed and coated with glue, and can be held on the holding mechanism 47.

  Next, as for the second embodiment, in addition to using the label printer 20 provided with the cutter device 21 similar to the conventional one and providing the coater 30, the outlet side sensor 44 of the coater 30 is provided. The connection is made with the cable 55 so that the label printer 20 operates only when the no label state is detected.

  According to the second embodiment, when the label piece 32 that is printed by the printer 20 and has no glue on the back surface is inserted from the insertion port 41 of the coater 30, the transport mechanisms 45 and 46 and the glue application mechanism 47 operate. Starting, the paste is applied to the back surface of the label piece 32 and discharged to the holding mechanism 47 on the discharge port 42 side.

  Therefore, the adhesive label can be issued on demand. In particular, the outlet side sensor 44 does not have to work in preference to the inlet side sensor, and the inlet side sensor 42 of the coater 30 does not have to be provided.

  The embodiment described above is merely an example, and is not limited to this embodiment. Various modifications can be made without departing from the scope of the present invention.
