In the description of the present embodiment, the printing apparatus 50 that performs printing on the label portion of the medium 10 that has been subjected to the half-cut process on the label base material temporarily attached to the label mount, and the medium 10 that has been discharged from the printing apparatus 50 is not used. A printing system 200 including a label paper take-up device 100 that peels and collects a label portion from a label mount and winds the label together with the label mount will be described.

  The printing apparatus 50 is an image forming apparatus that includes a print engine such as an electrophotographic system or an inkjet system, and prints arbitrary information on a label portion of the medium 10 supplied from the roll paper feeder 51. The medium 10 is set on the roll paper feeder 51 in a wound state, and is continuously supplied into the printing apparatus 50 as the roll paper feeder 51 rotates in the direction of arrow A in FIG. As described above, the medium 10 has a label base material temporarily attached to the surface of the label mount. The half cut applied to the label base material is a form in which the half cut processing is performed inside the printing apparatus 50 even if the medium 10 that has been previously subjected to the half cut processing is used as the medium 10. It may be.

  The label paper take-up device 100 takes up the label 10a together with the label mount while separating and collecting the debris 10b, which is a non-label portion, from the medium 10 discharged from the printing device 50. Such a label paper take-up device 100 includes a tension bar 101 serving as a label peeling portion, a tension bar working frame 102, a tension bar position sensor 103, an idle roller 104 serving as a roller member, a peel bar 105 serving as a scrap guide portion, and a label. A winding unit 106 and a residue winding unit 107 serving as a residue winding unit are provided.

  The tension bar 101 generates a slack between the printing apparatus 50 and the label winding unit 106, and generates a winding timing. The tension bar 101 is configured to be slidable within the tension bar operating frame 102 while constantly applying tension to the medium 10 in the direction of arrow B in FIG. Absorbs the difference in the medium conveyance speed between the two. The vertical position of the tension bar 101 is detected by a tension bar position sensor 103. In the present embodiment, when the tension bar position sensor 103 detects that the tension bar 101 is positioned at the lowermost end of the tension bar operating frame 102, the control unit 20 described later drives the label winding motor 21 to perform label winding. The take-up unit 106 is rotated, and the duck winding motor 22 is driven to rotate the duck winding unit 107. On the other hand, when the tension bar position sensor 103 detects that the tension bar 101 is positioned at the uppermost end of the tension bar operating frame 102, the control unit 20 stops the label winding motor 21 and the residue winding motor 22.

  The idle roller 104 is provided downstream of the tension bar 101 in the medium conveyance direction, and generates a label winding angle. The configuration of the idle roller 104 will be described later.

  The peel bar 105 is disposed apart from the idle roller 104, guides the residue 10b to the residue winding unit 107, and generates a peeling angle when peeling the residue depending on the positional relationship with the idle roller 104. That is, the peel bar 105 is separated into a residue 10b wound up by the residue winding part 107 and a label 10a to be taken up by the label take-up part 106.

  The label take-up unit 106 rotates in the direction of arrow C or D in FIG. 1 by the driving force transmitted from the label take-up motor 21, and winds the label 10a of the medium 10 discharged from the printing apparatus 50 together with the label mount. take. The label take-up unit 106 is configured to be able to switch the rotation direction to either depending on whether the label 10a (label mount) is taken up by the face-in method or the face-out method.

  The residue winding unit 107 rotates in the direction of arrow E in FIG. 1 by the driving force transmitted from the residue winding motor 22 to wind up the residue 10b that is a non-label portion of the medium 10 discharged from the printing apparatus 50.

  FIG. 2 is a block diagram illustrating a functional configuration of the label winding device 100 according to the present embodiment. The label winding device 100 includes a control unit 20, a tension bar position sensor 103, a peel bar sensor 121 as a second detection unit, an idle roller sensor 123 as a first detection unit, and a label winding motor 21. And a dwindling motor 22.

  The control unit 20 comprehensively controls the entire label paper take-up device 100. The control unit 20 determines the position of the tension bar 101 in the tension bar operating frame 102 based on information from the tension bar position sensor 103, and controls the driving or stopping of the label winding motor 21 and the residue winding motor 22 based on the determination result. To do. Further, the control unit 20 counts the linear velocity and the pulse width of the medium 10 traveling on the idle roller 104 from the pulse width output from the idle roller sensor 123 described later, and the label 10a wound on the label winding unit 106. Estimate the winding diameter. Then, the control unit 20 controls the rotation speed of the label winding unit 106 so that the rotation speed is always faster than the discharge speed of the medium 10 from the printing apparatus 50. Further, when there is no change in information output from the peel bar sensor 121 described later, the control unit 10 stops the label winding motor 21 and the residue winding motor 22.

  One or a plurality of tension bar position sensors 103 are arranged along the tension bar operating frame 102 shown in FIG. 1, and output the position of the tension bar 101 in the tension bar operating frame 102 to the control unit 20. Based on the input result from the tension bar position sensor 103, the control unit 20 controls the start and stop of driving of the label winding motor 21 and the like.

  The peel bar sensor 121 is a sensor that outputs the rotation state of the peel bar 105 to the control unit 20 as a detection signal. The configuration and the like of the peel bar sensor 121 will be described with reference to FIG.

  The idle roller sensor 123 is a sensor that outputs the rotation state of the idle roller 104 (linear speed and pulse width of the medium 10 traveling on the idle roller 104) to the control unit 20 as a detection signal. The configuration of the idle roller sensor 123 will also be described with reference to FIG.

  The label winding motor 21 is a driving motor that is driven based on an instruction from the control unit 20 and rotates the label winding unit 106.

  The residue winding motor 22 is a drive motor that is driven based on an instruction from the control unit 20 to rotate the residue winding unit 107.

  Next, the configuration of the idle roller 104 and the peel bar 105 according to the present embodiment will be described with reference to FIGS. 3 (a), 3 (b), and 3 (c). FIG. 3A is a partially enlarged view for explaining the configuration of the idle roller 104 and the peel bar 105, and FIG. 3B is a view seen from the direction of the arrow X in FIG. FIG. 3C is a diagram for explaining an example of the pulse width output by the idle roller sensor 123.

  The idle roller 104 is in contact with a roller body 104a formed in a cylindrical shape, a roller shaft 104b that pivotally supports the roller body 104a, and a flange 104c formed on the outer periphery of the roller shaft 104b. And a slit support 104d that rotates along with the rotation of the roller body 104a. The idle roller 104 is configured to be able to rotate in the clockwise direction or the counterclockwise direction by the tension accompanying the rotation of the label winding unit 106 or the residue winding unit 107. As shown in FIG. 3B, the slit support portion 104d is connected to a first slit plate 122 having openings 122b formed at predetermined intervals along the circumferential direction of the disc portion 122a. The idle roller sensor 123 serving as a detection unit disposed so as to sandwich the slit plate 122 detects light transmission / non-transmission in the opening 122b or the disc 122a, and has a pulse width as shown in FIG. Output as. When the pulse width output from the idle roller sensor 123 is large (the upper stage in FIG. 3C), the control unit 20 estimates that the winding diameter of the label 10a wound around the label winding unit 106 is large. When the pulse width output from the idle roller sensor 123 is small (the lower stage in FIG. 3C), it is estimated that the winding diameter of the label 10a wound around the label winding section 106 is small.

  Returning to FIG. 3A, the peel bar 105 provided just above the position where the idle roller 104 is disposed guides the residue 10 b from the medium 10 to the residue winding unit 107. The peel bar 105 includes a bar main body portion 105a and a support portion 105b that rotatably supports the bar main body portion 105a. A second slit plate 120 having openings 120b formed at predetermined intervals along the circumferential direction of the disc portion 120a is connected to the support portion 105b. A peel bar sensor 121 serving as a detection unit arranged so as to sandwich the second slit plate 120 detects transmission / non-transmission of light in the opening 120b or the disc 120a. Specifically, the peel bar sensor 121 outputs a detection result at the opening 120b or the disc 120a of the second slit plate 120 to the control unit 20 with a value of “1” or “0”. If the residue 10b is normally wound up, the peel bar 105 continues to rotate, and the detection value of the peel bar sensor 121 is “1” or “0” repeatedly. However, when the residue breaks, the peel bar 105 and the second slit plate 120 connected to the support part 105b do not rotate, so that the detection value of the peel bar sensor 121 remains “1” or “0”. And the control part 20 which functions also as a residue cutting | disconnection detection part detects generation | occurrence | production of waste scraps by monitoring the output value of the peel bar sensor 121 within the predetermined time.

  Next, the processing of the printing system 200 according to the present embodiment having the above-described configuration, in particular, the label paper take-up device 100 will be described with reference to FIGS. 1, 2, 3, 4, and 5. FIG. 4 is a flowchart for explaining the operation of the label paper take-up device 100 according to this embodiment. FIGS. 5A to 5F show the state of the label paper take-up device 100 in each step of the flowchart of FIG. It is an operation | movement figure to demonstrate.

  First, in step S <b> 10, in order to wind the medium 10 around the label winding unit 106 of the label paper winding device 100, the user discharges a predetermined amount of the medium 10 from the printing device 50, and the label winding unit 106. (This state is illustrated in FIG. 5 (a)).

  The medium 10 is discharged from the printing apparatus 50, and the tension bar 101 starts to descend. The control unit 20 monitors the output of the tension bar position sensor 103 until the tension bar 101 reaches the lowermost end of the tension bar working frame 102 (this state is illustrated in FIG. 5B). When the tension bar 101 reaches the lowermost end of the tension bar working frame 102 (Yes in step S11), the control unit 20 drives the label winding motor 21 to rotate the label winding unit 106 and the scrap winding motor 22 to rotate. Driven to rotate the residue winding unit 107 (step S12). Here, the control unit 20 counts the linear velocity and pulse width of the medium 10 traveling on the idle roller 104 from the detection information of the idle roller sensor 123, and winds the label 10a wound on the label winder 106. While estimating the diameter, the rotation speed of the label winding unit 106 is controlled (this state is illustrated in FIG. 5C).

  Subsequently, the control unit 20 monitors whether the position of the tension bar 101 in the tension bar operating frame 102 is a stop condition or activation information of each motor based on the output value of the tension bar position sensor 103. Here, when the tension bar 101 reaches the uppermost end in the tension bar working frame 102, which is a stop condition of each motor (the uppermost end of step S13), the control unit 20 switches the label take-up motor 21 and the residue take-up motor 22 to each other. Stop (step S14). At this time, the rotation of the label winding unit 106 is stopped, but the tension bar 101 is lowered because the medium 10 is continuously discharged from the printing apparatus 50.

  On the other hand, when the tension bar 101 is located at a position other than the uppermost end in the tension bar working frame 102, which is a stop condition of each motor (step S13 other than the uppermost end), the control unit 20 determines from the detection information of the idle roller sensor 123. The rotational speed of the label winding unit 106 is controlled while counting the linear velocity and pulse width of the medium 10 traveling on the idle roller 104 and estimating the winding diameter of the label 10a wound around the label winding unit 106. Then, the rotation of the label winding unit 106 and the residue winding unit 107 is continued (step S15).

  Then, the control unit 20 monitors whether or not the output value of the peel bar sensor 121 is constantly changing. Specifically, the control unit 20 determines whether the output of the peel bar sensor 121 continuously acquired within a predetermined period (for example, 10 seconds) is “0” or “1” repeatedly. Determine the occurrence of When the rotation of the peel bar 105 is stopped (step S16 is stopped), when the output value of the peel bar sensor 121 is not changed, the control unit 20 determines that the waste of the waste has occurred, and the label take-up motor 21 and the waste take-up The motor 22 is stopped (step S17, this state is illustrated in FIG. 5D). On the other hand, when the rotation of the peel bar 105 is continued (the rotation in Step S16), the control unit 20 returns the process to Step S15.

  Next, in step S <b> 17, the control unit 20 determines the winding diameter of the label paper 10 a that is wound around the label winding unit 106 based on the pulse width output from the idle roller sensor 123 when it is determined that the waste is broken. (Step S18), and the output of the tension bar position sensor 103 is monitored until the tension bar 101 reaches the lowermost end of the tension bar operating frame 102. When the tension bar 101 reaches the lowermost end of the tension bar operating frame 102 (YES in step S19), the control unit 20 stops the discharge of the medium 10 by the printing device 50 (step S20).

  In step S <b> 21, the control unit 20 is necessary for re-attaching the residue 10 b to the residue winding unit 107 again based on the winding diameter of the label 10 a wound around the label winding unit 106 estimated in step S <b> 18. The label winder 106 is rotated and stopped by the distance (predetermined distance) of the residue 10b (this state is illustrated in FIG. 5E). Note that the distance at which the residue 10b is attached again is a length that is equal to or longer than the distance between the peel bar 105 and the residue winding part 107, and the distance at which the residue 10b can be attached again to the residue winding part 107. It is.

  When the waste 10b is reset in the waste winding unit 107 (step S22) and restarted by the user, the control unit 20 drives the label take-up motor 21 and the waste winding motor 22 so that the tension bar 101 is It moves to the uppermost end of the tension bar working frame 102 (step S23). Then, the control unit 20 stops driving the label winding motor 21 and the residue winding motor 22 and waits (this state is illustrated in FIG. 5F).

  As described above, according to the present embodiment, when the rotation of the peel bar for peeling the residue is detected by the peel bar sensor as the second detection unit and it is determined that the residue is broken, Based on the detection result of the idle roller sensor as the first detection unit for detecting the rotation of the idle roller, the necessary distance of the waste required for the resetting of the waste is estimated, and the label paper winding diameter is estimated. By transporting the necessary distance, it is possible to easily reset from the waste portion.
