Description

  Embodiments described herein relate generally to a label printer.

  Usually, in the structure of a label paper wound in a roll shape, a label having an adhesive layer on a mount is attached with a gap at regular intervals. The cutting unit of the printer cuts the gap between the labels. Therefore, in the case of a label with a mount, the adhesive layer of the label is not cut, so that no glue adheres to the blade of the cut portion.

  On the other hand, in recent years, long non-mounting label sheets without a mount have appeared. In the case of the label paper without the mount, the printer cuts the label paper without the mount while guiding the label paper without the mount to the stage provided at the label discharge port. The stage will continue to receive the label after cutting after printing. Such a stage is provided with a non-adhesive process that prevents the adhesive layer on the back side of the label cut after printing from sticking. By performing such non-adhesive processing, it is possible to prevent occurrence of paper discharge clogging due to sticking of a label cut after printing to the stage.

  However, when a long label is generated or when there is an influence of wind or the like, there is a problem that the label falls from a stage subjected to non-adhesive processing. Thus, the label dropped from the stage cannot be used because the adhesive layer on the back side of the label sticks to the floor or the like.

  The problem to be solved by the present invention is to provide a label printer that can avoid dropping of a label from a stage.

  The label printer according to the embodiment prints on a storage unit that stores a roll-shaped label sheet in which an adhesive layer is provided on the back side of a printing surface to be printed, and the label sheet that is drawn out and conveyed from the storage unit. A printing unit that performs printing, a cutting unit that is provided on the downstream side of the printing unit in the sheet conveyance direction, and that sequentially cuts the label sheets after printing by moving a lower movable blade toward an upper fixed blade; A stage that is provided on the downstream side of the cutting unit in the sheet conveying direction and receives the label cut by the cutting unit, and the cutting edge of the movable blade is non-adhesive except for a region that first meshes with the fixed blade Processing has been applied.

  The storage unit 8 stores the label paper L and the holder 7 as described above. The storage unit 8 stores the label paper L as it is when the label paper L that does not require the holder 7 is used.

  The front cover 5 is provided with a member (hereinafter referred to as a stage) 53 that receives a label X (see FIG. 5) after printing and cutting. The front cover 5 covers the front surface of the printer main body 2 so that it can be opened and closed, and opens or closes to the outside. A label discharge port 60 for discharging the label X is provided between the upper end portion of the front cover 5 and the lower front end portion of the upper case 4.

  The printer main body 2 includes a print head 22 and a platen roller 23. The print head 22 and the platen roller 23 constitute a print unit. The print head 22 includes a thermal head (not shown) having a heating element (not shown), a controller 24, and the like, and prints information on the printing surface of the label paper L. The platen roller 23 uses the motor 25 and a drive gear (not shown) to convey the label paper L and press the label paper L against the print head 22.

  As shown in FIG. 3, the printer main body 2 includes a fixed blade 91 and a movable blade that are opposed to the platen roller 23 on the downstream side in the paper transport direction and on the front side of the front cover 5 with the paper transport path therebetween. The so-called guillotine-type cutting part 9 provided with 92 is provided. The movable blade 92 of the cutting part 9 is inclined from one end (upper side) to the other end (lower side). Although details will be described later, the cutting unit 9 moves the movable blade 92 with respect to the fixed blade 91 and sequentially meshes the movable blade 92 along the width direction of the fixed blade 91. Accordingly, the cutting unit 9 sequentially cuts the label paper L sandwiched between the fixed blade 91 and the movable blade 92 from one end to the other end.

  In the present embodiment, the back surface of the label X cut after printing, except for the partial area A1 (see FIG. 4) on the upper side of the inclination of the movable blade 92, at the cutting edge of the movable blade 92 of the cutting unit 9. Non-adhesive processing is applied to prevent the adhesive layer from sticking. That is, the adhesive layer on the back surface of the label X (see FIG. 5) cut after printing is attached to a partial area A1 on the upper side of the inclination of the movable blade 92. In this case, the cutting edge of the movable blade 92 is subjected to non-adhesive processing as a whole, and then the non-adhesive in the partial region A1 (the region first meshed with the fixed blade 91) A1 on the upper side of the inclination of the movable blade 92. Processing is removed.

  The controller 24 connects the touch panel display 41, the platen roller 23, the print head 22, the motor 25, and the home position sensor 26. Thereby, the controller 24 controls each process such as conveyance, printing, and cutting of the label paper L. The controller 24 controls various screens displayed on the touch panel display 41.

  That is, the platen roller 23 is rotationally driven by a motor 25 driven under the control of the controller 24, pulls out the free end side of the label paper L wound in a roll shape, and the direction of the label discharge port 60 (paper) Transport in the transport direction).

  The print head 22 sandwiches the platen roller 23 and the label paper L, and prints information on the print surface of the label paper L being conveyed according to the control of the controller 24. Thereafter, the label sheet L is conveyed to the cutting position of the label sheet L by the cutting unit 9 by the rotational driving of the platen roller 23 according to the control of the controller 24. Then, the label paper L is cut at the cutting position by the cutting unit 9 driven according to the control of the controller 24. Note that the label paper L that has been transported to the location cut by the cutting unit 9 is guided to the stage 53 provided on the front cover 5. The stage 53 continues to receive the label X (see FIG. 5) after the print cut even after the print cut.

  Here, the cutting mechanism by the cutting unit 9 will be described. Here, FIG. 4 is a front view schematically showing a cutting mechanism by the cutting section 9. FIG. 4 shows the cutting unit 9 as viewed from the printing unit side. As shown in FIG. 4, the drive unit 90 that drives the cutting unit 9 includes the motor 25 described above, a disk 93, and a pin 93 a provided on the disk 93. The drive unit 90 is monitored by a signal output from the home position sensor 26 attached.

  The disk 93 constitutes an eccentric mechanism having a pin 93a at a position away from the center point where the shaft 25a of the motor 25 is attached. That is, the disk 93 can change the rotational motion to the reciprocating motion of the pin 93a. The pin 93a is inserted into a groove 92a provided in the movable blade 92.

  The shape of the groove 92a provided in the movable blade 92 is a rectangular shape. The size of the vertical groove 92a in which the movable blade 92 moves is substantially the same as the diameter of the pin 93a. On the other hand, the size of the groove 92a in the left and right direction perpendicular to the vertical direction is substantially the same as the diameter of the circular orbit of the pin 93a.

  Therefore, even when the motor 25 rotates and the pin 93a provided on the disk 93 moves in a circular path, the movable blade 92 does not move in the left-right direction but moves in the up-down direction. That is, the movable blade 92 is pushed up from the home position toward the fixed blade 91 by the rotational drive of the motor 25 driven in accordance with the control of the controller 24, and the blade edge of the movable blade 92 that interferes with the fixed blade 91 first. Engage in order from the higher side. Therefore, the label paper L between the lower movable blade 92 and the upper fixed blade 91 is sequentially cut from one end portion to the other end portion. The home position is, for example, the lowest point when the movable blade 92 moves up and down.

  The home position sensor 26 detects whether or not the movable blade 92 is at the home position. The home position sensor 26 outputs a signal indicating the ON state when the movable blade 92 is at the lowest home position, and indicates the OFF state when the movable blade 92 is not at the lowest home position. Is output. That is, the home position sensor 26 is a sensor that detects that the movable blade 92 cuts the label paper L and returns to the home position. Thus, the controller 24 can detect the start and completion of cutting of the label paper L by receiving a signal from the home position sensor 26.

  The label X cut after printing as described above is held in a state of being received by the stage 53.

  As shown in FIGS. 1 and 2, the stage 53 includes a plurality of elongated protrusions 53a on the upper surface 53c substantially in parallel. That is, the convex part 53a is provided in the shape of a rib. The reason why the upper surface 53c of the stage 53 is provided with the rib-like convex portion 53a is to prevent the adhesive layer on the back surface of the label X cut after printing from sticking. By performing such processing, it is possible to prevent the occurrence of paper discharge clogging due to the label X cut after printing being attached to the stage 53.

  Next, the relationship between the stage 53 and the movable blade 92 of the cutting part 9 will be described. Here, FIG. 5 is a longitudinal side view showing the state of the label X cut after printing.

  As shown in FIG. 5, the stage 53 is provided at a position higher than the upper side of the inclination of the movable blade 92 of the cutting portion 9 located at the home position.

  The reason why the positional relationship between the stage 53 and the movable blade 92 of the cutting unit 9 is as described above is as follows.

  Since the long non-mounting label paper L without the mount can be cut at an arbitrary position, the non-adhesive processing is performed when the long label X is generated or when there is an influence of wind or the like. There is a problem in that the label X falls from the stage 53 to which is applied. Thus, the label dropped from the stage cannot be used because the adhesive layer on the back side of the label sticks to the floor or the like.

  Therefore, in the present embodiment, non-adhesive processing is performed except for a partial region (region that first meshes with the fixed blade 91) A1 on the upper side of the inclination of the movable blade 92 of the cutting portion 9, and in the movable blade 92. The stage 53 is provided at a position higher than the upper side of the inclination. Accordingly, the movable blade 92 returns to the home position while the adhesive layer on the back surface of the label X is attached to the partial area A1 on the upper side of the inclination. When the movable blade 92 returns to the home position, the label X is held in a state where it is placed on the stage 53 and in a state where an adhesive layer is attached to one point of the movable blade 92. Therefore, even when the long label X is generated or when there is an influence of wind or the like, the drop of the label X from the stage 53 can be avoided to some extent.

  As described above, according to the first embodiment, when the movable blade 92 returns to the home position, the label X is placed on the stage 53 and the adhesive layer is attached to one point of the movable blade 92. Held in. Therefore, the label printer 1 can avoid the dropping of the label X from the stage 53 to some extent even when a long label X is generated or when there is an influence of wind or the like.
