Description

  The present invention relates to a printer, for example, a label printer that prints desired information such as characters, symbols, figures, bar codes, and the like on a label temporarily attached to a mount, and peels off the label to issue it. The present invention relates to a label printer having an issuing function.

  For example, a label printer is configured to rotate a platen roller with one longitudinal end of a continuous label roll wound between a thermal head and a platen roller, thereby feeding the continuous label into a sheet and transporting the continuous label. During printing, the printer prints desired information with a thermal head on each of a plurality of labels temporarily attached to a long backing sheet constituting a continuous label body.

  This label printer has two types of printing methods, continuous printing and peeling printing. The continuous issuance method is a method in which a label is temporarily attached to a mount, and is issued. The peeling issuance method is a method in which a label is peeled off from the mount and is issued.

  In the case of the continuous issuance method, the mount on which the required number of labels are attached is created by cutting, and the label can be peeled off from the mount on the spot and pasted. It is suitable when it is located in a place.

  On the other hand, in the case of the issuance of the peeling, the labels are discharged in a state of being peeled off from the backing sheet one by one, so that it is suitable when the object to which the label is to be attached is near the worker. When issuing the peeling, the peeling unit (peeling mechanism unit) mounted on the printer is installed at the peeling issue position, and one end in the longitudinal direction of the backing sheet is bent via a peeling pin, and then the peeling roller of the peeling unit and the platen roller To be sandwiched between. With this, when the platen roller is rotated for printing and the continuous label is transported, the backing sheet is transported sandwiched between the peeling roller and the platen roller, while the printed label is peeled off from the backing sheet by sheet. Is discharged outside the machine

  As a printer provided with two types of issuance methods, that is, continuous issuance and peeling issuance, for example, a printer described in Patent Literature 1 is known.

  Next, the internal structure of the printer 1 will be described with reference to FIGS. FIG. 7 is a schematic configuration diagram showing the inside of the printer of FIG. 1 in a peeling issue state from the side, and FIGS. 8A and 8B are enlarged schematic configurations of main parts of the printer of FIG. FIG.

  As shown in FIG. 7, a print main body 26 is installed in the opening 2 a of the main body case 2 so as to be adjacent to the paper storage unit 6. The printing body 26 is a functional unit for printing on the label PL of the label continuum P, and includes a head bracket 27, a thermal head (printing head) 28 (see FIG. 8B), and a coil spring 29 ( 8), a peeling unit 4, and a battery housing 33 (see FIG. 7).

  The head bracket 27 is a member that holds the open / close cover 3 in a closed state. The head bracket 27 is mounted on the main body case 2 in a state where the head bracket 27 is swingable about a rotation shaft 27a on the opposite side of the platen roller 10 at the closed position of the opening / closing cover part 3.

  The head bracket 27 has a groove 27b. The opening / closing cover 3 is held by the head bracket 27 by fitting the platen shaft 10a of the platen roller 10 into the groove 27b.

  The head bracket 27 has a pressing portion 27c. The pressing portion 27c is arranged at a position (directly below) facing the cover open button 18 shown in FIG. 1. When the cover open button 18 is pressed, the pressing portion 27c is also pressed, and the opening / closing cover portion 3 by the head bracket 27 is opened. Is released. When the holding state of the opening / closing cover 3 is released, the opening / closing cover 3 is automatically opened by the urging force of the torsion spring 35 (see FIG. 7) disposed at the other end in the longitudinal direction. Has become.

  The thermal head 28 (see FIG. 8B) is a printing unit that prints information such as characters, symbols, figures or bar codes on the label PL, and the platen roller 10 at the closed position of the opening / closing cover 3. The thermal head 28 is mounted on the head bracket 27 via the circuit board 36 in such a manner that the printing surface of the thermal head 28 faces the paper feeding route so as to face the paper bracket. On the printing surface of the thermal head 28, a plurality of heating resistors (heating elements) that generate heat when energized are arranged side by side along the width direction of the label continuous body P (the short direction of the backing paper PM). The circuit board 36 is a wiring board that transmits a print signal to the thermal head 28.

  The coil spring 29 (see FIG. 8) is a member that urges the head bracket 27 and the thermal head 28 toward the platen roller 10 by placing the coil bracket 29 at the closed position of the opening / closing cover 3, and on the back side of the head bracket 27 (the circuit board 36. (The back side of the mounting surface). Since the head bracket 27 is pushed toward the platen roller 10 by the urging force of the coil spring 29, the platen shaft 10 a fitted in the groove 27 b of the head bracket 27 is also firmly pressed, and the opening and closing cover 3 is held by the head bracket 27. State is maintained.

  Here, as shown in FIG. 8B, the unit pressing part 3a of the opening / closing cover part 3 is arranged in a gap between the eaves part 4cp of the peeling unit 4 and the leaf spring 4da when the peeling is issued, and comes into contact with the leaf spring 4da. The peeling unit 4 is pressed by pressing in a state in which the peeling unit 4 is pressed. As a result, the peeling unit 4 is fixed at the peeling issue position, and the peeling roller 4 a of the peeling unit 4 is urged toward the platen roller 10. Therefore, the peeling roller 4a of the peeling unit 4 can be urged firmly and stably to the platen roller 10 when the peeling is issued.

  Next, continuous issuance and peeling issuance of the printer 1 will be described with reference to FIGS. 9A is a schematic configuration diagram of the printer at the time of continuous issuance of FIG. 1A, and FIG. 9B is a schematic configuration diagram of the printer at the time of peeling issuance of FIG. 1B.

  In both of the continuous issuance and the peeling issuance, in the printing process, the platen roller 10 is rotated in a state where the label continuous body P fed from the paper storage unit 6 is sandwiched between the thermal head 28 and the platen roller 10. Conveys the label continuous body P. At the time of this conveyance, the printing timing is planned based on the information detected by the sensor 12, and the heat generating resistor of the thermal head 28 is selectively heated by the print signal transmitted to the thermal head 28, so that the label of the label continuous body P The desired information is printed on the PL.

  Here, in the continuous issuance, as shown in FIG. 9A, the peeling unit 4 is arranged at a continuous issuance position inside the printer 1. The printed label PL is discharged without being peeled from the backing paper PM. In the case of continuous issuance, a mount PM on which the required number of labels PL are pasted is created, and the label PL can be peeled off from the mount PM and pasted on site. Suitable for remote locations.

  Note that, as shown in FIG. 9A, at the continuous issuing position, the peeling roller 4a is stored inside the main body case 2. As a result, the protrusion of the peeling roller 4a from the main body case 2 is eliminated, making it difficult for the worker to touch the hand, and the deterioration of the peeling roller 4a is prevented.

  On the other hand, in peeling issuance, as shown in FIG. 9B, the peeling unit 4 is arranged at the peeling issuance position, and the mount paper PM is separated via the peeling pin 11 from the peeling roller 4a and the platen roller 10 of the peeling unit 4. Between them. Thereby, when the platen roller 10 is rotated for printing and the label continuous body P is transported, the backing paper PM is transported sandwiched between the peeling roller 4a and the platen roller 10, while the label PL after printing is 1 Each sheet is peeled off from the backing paper PM and discharged outside the machine. In the case of peeling issuance, the labels PL are ejected one by one, which is suitable when the object to which the label PL is to be attached is near the worker.

  In the printer 1 according to the present embodiment, continuous issuance and peeling issuance can be switched, and one situation can be dealt with when the object to which the label PL is to be attached is near or far from the printer 1. Easy to use and economical.

  Next, the support table 41 to which the peeling unit 4 is attached will be described with reference to FIGS. 10, 11, and 12. FIG. 10 is a perspective view showing the peeling unit and the support at the continuous issuing position, FIG. 11 is a side view of the peeling unit and the support in FIG. 10, and FIG. 12 is a view of the first mounting piece of the support in FIG. It is explanatory drawing shown in the relationship between the component formed in the surface facing a 2nd mounting piece, and a peeling unit.

  The support table 41 is provided in the opening 2a of the main body case 2 and has a pedestal section 41a to which a peeling sensor 43, which is a light reflection type sensor that detects the presence or absence of the label PL when peeling is issued, is attached. . A pair of unit mounting portions 41b for mounting the peeling unit 4 is formed at both ends in the width direction of the pedestal portion 41a.

  The unit mounting portion 41b includes a first mounting piece 41ba located outside when viewed from the width direction of the pedestal portion 41a, and a second mounting piece 41bb positioned inside and facing the first mounting piece 41ba. The first mounting piece 41ba and the second mounting piece 41bb sandwich the support 4c of the peeling unit 4 in a state where a slight gap is formed.

  The shaft 42 is attached to the unit attachment portion 41b so as to straddle the first attachment piece 41ba and the second attachment piece 41bb. The shaft 42 is inserted into a guide rail hole 4ch formed in the support portion 4c sandwiched between the first mounting piece 41ba and the second mounting piece 41bb. That is, the guide rail hole 4ch is engaged with the shaft 42.

  Therefore, the peeling unit 4 is slidable along the shaft 42 by moving the guide rail hole 4ch along the shaft 42, and is swingable about the shaft 42 as a fulcrum.

  Further, as shown in FIGS. 10 and 11, a coil spring 44 is mounted between the peeling unit 4 and the support 41. One end of the coil spring 44 is fixed to a mounting projection 41bc formed at one end of the first mounting piece 41ba of the unit mounting portion 41b, and is bent in a substantially L-shape therefrom to the side surface of the first mounting piece 41ba. The other end is attached to the mounting projection 4ci formed on the other end in the longitudinal direction of the support portion 4c (the side opposite to the mounting position of the peeling roller 4a in the longitudinal direction). Have been. Further, the shaft 42, which is the above-described swing shaft, is located on the side where a line connecting both ends of the coil spring 44 is drawn with respect to the coil spring 44 thus curved. The reason why the coil spring 44 is curved by the guide eaves 41bd is to obtain a necessary tensile force without taking up space.

  With such a structure, the peeling unit 4 is provided with an urging force in the direction in which the mounting projection 4ci side of the guide rail hole 4ch abuts on the shaft 42 (the direction opposite to the continuous issuing position) by the coil spring 44. An urging force is exerted by the urging force to swing in a direction (first direction) away from the thermal head 28 with the mounting protrusion 4ci side of the guide rail hole 4ch contacting the shaft 42 as a fulcrum. That is, the coil spring 44 applies two biasing forces to the peeling unit 4, a biasing force for sliding movement and a biasing force for swinging in the first direction.

  Accordingly, when the holding state held at the continuous issue position is released by the release lever portion 19, the peeling unit 4 moves (slides) to the opposite side to the continuous issue position by the urging force of the coil spring 44, and moves along the guide rail. One end of the hole 4ch abuts on the shaft 42 (sliding position), and swings around the shaft 42 in a first direction to a predetermined swing end (swing end position).

  Here, as shown in FIG. 12, the support portion 4c of the peeling unit 4 has a first claw portion 4cj located on one side in the short direction of the guide rail hole 4ch and a second claw portion located on the other side. Are formed, respectively. Further, a first protruding portion 41be and a second protruding portion 41bf are formed on a surface of the first mounting piece 41ba facing the second mounting piece 41bb.

  When the peeling unit 4 slides along the shaft 42 from the continuous issuing position to the opposite side along the first protrusion 41be, the first claw 4cj slides to move the peeling unit 4. A guide surface 45 for guiding the direction is formed. As described above, when the peeling unit 4 swings about the shaft 42 in the first direction in the first direction, the first protrusion 4be comes into contact with the first protrusion 41be to define the swing end position. A first stopper 46 is formed. Further, when the peeling unit 4 swings from the swing end position in the second direction opposite to the first direction and shifts to the peeling issue position, the first protrusion 41be has the first claw. A regulating surface 47 is formed to regulate the portion 4cj from sliding to return the peeling unit 4 to the continuous issuing position.

  The pivoting end position of the peeling unit 4 where the first claw portion 4cj contacts the first stopper 46 is opened and closed at one end side (tip end side) of the peeling unit 4 facing the opening / closing cover 3. The position is located within the swing locus of the cover 3.

  On the other hand, when the peeling unit 4 is at the peeling issuance position, the second claw 4ck is in contact with the second protruding portion 41bf, and the second protrusion 41bf is for preventing the peeling unit 4 from returning to the continuous issuance position. Two stoppers 48 are formed.

  Next, setting of the continuous issue position and the peel issue position in the peeling unit 4 of the printer 1 of the present embodiment will be described with reference to FIGS. 13 to 18 and FIG. FIG. 13 to FIG. 15 are schematic configuration diagrams of a main part of the printer showing a state of the peeling unit and the opening / closing cover when the peeling unit is set to the peeling issuing position. FIGS. It is explanatory drawing which shows the relationship between the peeling unit and the support when setting.

  FIG. 14A shows a stage before setting the peeling unit 4 when the peeling unit 4 is set to the peeling issuing position. The peeling unit 4 in the pre-setting stage is disposed so as to project obliquely with respect to the upper surface of the printer 1 (the surface on which the issuing port is disposed).
