Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a label feeding apparatus,

The present invention relates to a label supply apparatus and a control method thereof.

Generally, labels are attached to products such as electronic parts such as devices, battery packs, circuit boards, and the like. The label includes a printing surface on which a manufacturing date, a manufacturing form, a logo, and the like are printed, and an adhesive surface on which the adhesive is applied on the back surface of the printing surface.

The label is produced with the release paper (that is, the label paper back) attached in the direction of the adhesive surface. The produced label is removed from the release paper to expose the adhesive surface, and the exposed adhesive surface is attached to the product so that the label is attached to the desired position of the product.

One way to attach the label to the product was to manually remove the label from the release sheet by the operator.

The manual labeling operation requires the operator to detach the label with the release paper from the release paper and to attach the label so that the adhesive side of the label can be attached to the correct position of the product.

 Therefore, the worker takes a long time to work by separating the release paper and attaching the label at the correct position, and the adhesive surface of the separated label is adhered to the hand of the worker who goes through the manual work, . Also, if the label does not stick to the correct position or if there is porosity between the label and the product due to incorrect attachment operation, the product often fails to easily fall off the label.

In order to solve such a problem, a device for automatically separating the label from the release paper and automatically attaching the label to the product has been developed and used.

At this time, in order to prevent the label separated from the release paper from falling down by the gravity, a label support for supporting the separated label and the release paper is provided.

Accordingly, the label separated from the release paper is adsorbed by the operation of the label adsorber using vacuum or the like, and the label is attached to the desired product.

However, in this case, since the separated label is placed on the label pedestal and the label adsorption operation is performed by the label adsorbing machine, the label and the label pedestal located below the label are adhered to each other, A problem that the label adsorption operation is not performed occurs.

In addition, since the adhesive is applied to the surface of the label base due to frequent contact between the label base and the adhesive side of the label, there is a problem of reducing the operation efficiency of the label adsorber.

First, a label supply apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. FIG.

The label feeding device according to an embodiment of the present invention shown in FIGS. 1 to 3 includes a label transferring unit (LAM) having a roller R11 and a label LA adhered to a label backing LB, A label sheet feed guide 60 for guiding the label sheet feeder LAM discharged from the label sheet feed roller unit 10 in the corresponding direction, A label separator 70 for separating the label from the label transfer sheet LAM and a label separator 70 for separating the label separator 70 in the backward direction A label separator moving part 71 and a roller R20 that move the label separator 70 in the forward direction (the direction toward the conveyance guide 60) or in the advancing direction (the reverse direction to the backward direction) LA) is separated and collects the label Fuji (LB) without the label attached. A label conveying path LAM that is wound around the label conveying paper roller unit 10 and a plurality of label conveying rollers 20 for transferring the label backing LB from which the label LA has been removed to the label furrow roller unit 20, R12-R19 of the label separator 70 are connected to the label separator moving unit 71 and the label separator moving unit 71 is rotated in the forward or reverse direction so that the label separator 70 can be moved in the forward direction or the backward direction A second motor (or a label moving actuator) M12 for controlling the rotating operation of the plurality of rollers R11 to R20; a label (not shown) separated from the label backing LB An air blowing part 50 for blowing air to the adhesive side of the label LA (that is, the back side of the label LA which is in contact with the label furge LB) 2 solenoid valves 41, 42, first and second solenoid valves 41, 42, respectively, The first and second regulators 411 and 421 and the first and second regulators 411 and 421 which determine whether or not the supply of the compressed air pressure is determined according to the operating states of the first and second solenoid valves 41 and 42 First and second cylinders 412 and 422 whose operating states change depending on whether or not the compressed air pressure is applied from the first and second regulators 411 and 421, (90).

The label sheet feed roller unit 10 is located at the left upper end of the body 90 and is integrally connected to the roller R11 and the roller R11 which are rotated in a predetermined direction as described above and the label sheet feeder LAM And a tape winding portion 101 for winding the tape.

Therefore, the tape conveying unit LAM is wound around the tape winding unit 101 and the tape winding unit 11 rotates together with the roller R11 as the roller R11 rotates in the corresponding direction (i.e., the arrow direction) (LAM) is unwound and ejected to the label conveying guide (60).

The label conveying guide guide 60 is located at a corresponding portion of the body 90 so as to be positioned below the label conveying and conveying roller unit 10 and has a rail on which the label conveying sheet LAM moves The label conveying path LAM discharged from the label conveying roller unit 10 moves toward the label separator 70 along the rail.

The label separator 70 is disposed in the body 90 located below the label conveying path LAM moved along the label conveying path guide 60 and is in contact with the label conveying path LAM, And a main body 702 which is fixedly connected to the pedestal 701 and moves along the label separator moving part 71 according to the operation of the first motor M11 to move backward or forward .

The label separator moving unit 71 is inserted into the main body 702 so that the main body 702 of the label separator moving unit 71 moves the label separator moving unit 71 in the backward or forward direction And the label separator 70 is moved backward or forward.

Therefore, when the main body 702 is moved backward along the label separator moving unit 71 as the label separator moving unit 71 moves in the corresponding direction (for example, the forward direction) by the operation of the first motor M11, The label fingers LB wound on the label separator 70 are also pulled toward the label conveying guide 60 so that the label fingers LB on the label fingers LB The label LA and the label label LB are separated from each other.

In this way, the label feeder of this embodiment can move the label separator 70 in the backward direction to separate the label LA from the label backing LB, so that the suction operation by the label adsorber 200 is performed by the label separator 70 (Before the operation of separating the label LA from the label backing LB is performed) before the backward movement of the label LA is performed.

The label adsorption operation by the label adsorber 200 is performed before the label LA is separated from the label backing LB by a predetermined amount or more (i.e., before the deflection phenomenon of the label LA separated downward) There is no problem that the adhesive surface of the label LA separated from the label backing LB by the deflection phenomenon of the label LA adheres to the portion located below the adhesive surface.

The label separator moving unit 71 is connected to the first motor M11 and the label separator 70 and rotates in the forward or reverse direction according to the operation of the first motor M11, So that the backward movement or the forward movement can be performed. The label separator moving part 71 is made of a ball screw.

The label fog roller unit 20 is installed on the body 90 under the label feed roller unit 10 and integrally connected to the roller R20 and the roller R20 that rotate in a predetermined direction, And a tape wrapping portion (201) around which the label backing (LB) on which the label (LA) is detached is wound by the operation of the tape wrapping portion (70).

Therefore, the tape winding portion 201 is also wound in the predetermined direction by the rotation of the roller 21, and the label furrow LB (LB), which is moved to the label fringe roller portion 20 by the action of the plurality of rollers R12- Is wound on the tape winding portion 201. [

The plurality of rollers R12 to R19 are disposed to be spaced apart from each other and are rotated in the predetermined direction by the rotation of the drive rollers R15 and R19 and the rotation of the drive roller R15 by the operation of the second motor M12 And an idle roller (R12-R14, R16-R18).

The label transferring paper LAB discharged from the label transferring roller unit 10 on the outer surfaces of the plurality of rollers R12-R19 and the label transferring paper LAB connected to the label transferring paper LAB, The label backing (LB) is wound in the appropriate direction without interruption.

Therefore, as the plurality of rollers R12-R19 rotate in the respective predetermined directions, the length of the label transferring paper LAM (or label fingernail LB) from the label conveying sheet roller portion 10 to the label fur roller 20 A moving operation is performed.

2, the roller R19 is directly connected to the second motor M12 so that the rotation of the roller R19 is performed in accordance with the rotation of the second motor M12, Since the roller R15 as the roller is connected to the timing belt T11, the driving roller R15 also rotates by the rotation of the roller R19.

The drive roller R15 and the label fringe roller R20 are also connected by a timing belt T12 so that the rotational force of the drive roller R15 is transmitted to the label fringe roller R20 via the timing belt T12, The label fur roller R20 is rotated to rotate the tape winding portion 201 in the corresponding direction.

The air firing portion 50 is positioned to overlap with a part of the pedestal 701 in the portion of the body 90 below the pedestal 701 of the label separator 70.

The air blowing part 50 is formed on a part of the air blowing part 50 which overlaps with a part of the pedestal 701 and is made of air which is opened toward the adhering face of the label LA and the label furrow LB And a passageway.

Accordingly, the label separator 70 operates to discharge air through the air passage to the label furrow LB and the adhesive surface, which is the back surface of the peeled label LA, so that the adhesive surface of the label LA is stuck downward Thereby preventing the phenomenon.

The air applied to the air launching part 50 is externally applied through an air passage. By the operation of the air ejection driving part 51 composed of a solenoid valve or the like, air discharged from the compressed air supply part is discharged to the air passage, (LA).

The first and second solenoid valves 41 and 42 are operated according to the state of the control signal applied thereto to control the compressed air supply state of the first and second regulators 411 and 421 as the compressed air generators .

As described above, the first and second cylinders 412 and 422 are operated according to the operating states of the first and second solenoid valves 41 and 42, depending on whether compressed air is supplied from the regulators 411 and 421, .

1, the first cylinder 412 is provided on the body 90 so as to be positioned above the label conveying path guide 60 and is provided with a label conveying sheet LAM ) Is controlled.

The second cylinder 422 is mounted on a corresponding portion of the main body 90 so as to be positioned adjacent to the rollers R16 and R17 and determines the positions of the rollers R16 and R17 positioned adjacent to the drive roller R15 And controls whether or not a pressure is applied to the label backing LB that moves to the label fibrillating roller portion 2 (0).

Accordingly, when the first cylinder 412 is operated, it is possible to prevent lifting of the label conveying paper (LAM) which moves due to the air pressure applied to the label conveying paper (LAM) discharged from the label conveying paper roller unit So that the suction operation of the label adsorber 200 and the label peeling operation by the label separator 70 can be stably performed.

When the second cylinder 422 to which air pressure is applied to the second cylinder 422 is operated, the rollers R16 and R17 are pushed by the drive roller R15 and the rollers R16 and R17 are driven by the drive roller R15. The rollers R16 and R17 are rotated by the rotation of the drive roller R15 to rotate the drive roller R15 and the label fingers LB and LB located between the rollers R16 and R17, And the label transfer sheet (LAM), which is continuously connected to the label transfer sheet (LAM).

On the other hand, when the second cylinder 422, in which the air pressure applied to the second cylinder 422 is discharged, is out of operation, the rollers R16 and R17 in contact with the drive roller R15 are driven by the drive roller R15, And releases the contact state between the drive roller R15 and the rollers R16 and R17.

As a result, the movement of the label transfer paper (LAM) attached to the label supply device and the label transfer paper (LB) connected to the label transfer paper (LAM) is stopped, and the label transfer paper (LAM) The connected label fingers LB are removed from the label feeder by the manager or a new label feeder LAM is mounted on the label feeder.

The structure of the control unit for controlling the operation of the label feeder having such a structure is shown in Fig.

The label conveying paper detecting section 11, the label detecting section 12, the label backing detecting section 13, the drive switch SW11, the pressure relief switch SW12, the pressure switch SW11, the pressure release switch SW12, An operation control unit 21 connected to the label conveying unit detecting unit 11, the label detecting unit 12 and the label backing detecting unit 13, a storage unit 22 connected to the operation controlling unit 21, A communication unit 23 connected to the operation unit 21, a warning unit 31 connected to the operation control unit 21, first and second motors M11 and M12 connected to the operation control unit 21, and an operation control unit 21 The first and second solenoid valves 41 and 42 and the air discharge driving unit 51 connected to the operation control unit 21.

The drive switch SW11 controls the operation of the label supply device. The drive switch SW11 changes the operation state according to the operation of the user, and outputs a signal corresponding to the operation state to the operation control unit 21.

The pressure release switch SW12 is for determining whether or not the air pressure applied to the first and second cylinders 412 and 412 is applied. The pressure release switch SW12 switches the operation state according to the user's operation, And outputs it to the control unit 21.

The label conveying path sensor unit 11 is positioned between the label conveying path roller unit 10 and the first cylinder 412 and is provided between the label conveying path roller unit 10 and the first cylinder 412, LAM), and outputs a detection signal of the corresponding state to the operation control unit 21 according to the presence or absence of the label transfer sheet (LAM) discharged from the label conveying and conveying roller unit 10.

The label conveying path sensor unit 11 detects whether the label conveying path unit LAM is normally ejected from the label conveying path roller unit 10 and whether the label conveying path roller unit 10 has a label conveying path For example.

The label sensing unit 12 is positioned on the upper portion of the air launching unit 50 which overlaps with the pedestal 701 of the label separator 70 so that the label sensing unit 12 is provided with the label F The detection signal of the corresponding state is outputted to the operation control unit 21. [

The label detecting unit 12 is for detecting whether or not the label transfer destination LAM has moved to the set position for label peeling operation in which the label LA is peeled from the label backing LB.

The label fog detecting section 13 is located between the label fog roller section 20 and the drive roller R15 and more specifically between the second cylinder 422 and the roller R17,

The detection signal of the corresponding state may be transmitted to the operation control unit (not shown) depending on whether the label furrow LB exists between the label fur roller unit 20 and the drive roller R15, that is, between the second cylinder 422 and the roller R17 21.

The label fog detecting unit 13 is for detecting whether the label fog LB with the label LA peeled off is normally transported and is normally wound by the label fog roller unit 20.

The sensing unit 11-13 may be a photo sensor including a light emitting unit for emitting infrared rays and a light receiving unit for receiving infrared rays.

The operation control unit 21 determines whether the label supply device is driven by using the signal output from the drive switch SW11 and controls the operation of the label supply device using the detection signal output from the sensing unit 11-13 And outputs the control signal.

The operation control unit 21 is connected to the first and second solenoid valves 41 and 42 that control the operation of the first and second cylinders 412 and 422 using the operation state of the pressure release switch SW12 So that the operation of the first and second cylinders 412 and 422 is controlled to the corresponding state.

The storage unit 22 stores data necessary for the operation of the label supply device and data generated during the control operation.

The communication unit 23 communicates with the label adsorber 200 that adsorbs the label LA attached to the label backing LB. The communication unit 23 communicates with the label feeder and the label adsorber 20 via the wireless Communication or wired communication is performed.

The warning unit 31 is a display unit for displaying the operation state of the label supply state 31 and may include at least one of a plurality of light emitting diodes and a buzzer.

Therefore, the manager of the label supply apparatus can quickly determine whether the label supply operation is normal or abnormal, using the operation state of the warning unit 31, so that an appropriate and quick subsequent operation can be performed.

The first and second motors M11 and M12 rotate in a corresponding direction according to a control signal output from the operation control unit 21 to control the operation of the connected label separator 70 and the drive roller R15.

The operation states of the first and second solenoid valves 41 and 42 are changed according to the control signal output from the operation control unit 21 to control the operation states of the cylinders 412 and 422.

The operation of the air firing drive part 51 is also changed according to the control signal outputted from the operation control part 21 to control whether the air firing part 50 discharges air.

Referring to Figs. 5A, 5B and 6, the operation of the control unit having such a structure will be described in detail.

First, with reference to FIGS. 5A and 5B, the operation of separating the label LA from the label transfer destination (LAM) will be described.

First, the label feeder (LAM) is moved toward the label adsorber 200 by using the label feeder, and the label feeder for the adsorption operation of the label LA by the label adsorber 200, (LAM) as shown in FIG.

When the power supply switch (not shown) operates to supply power to the label feeder, the label feeder is in a driveable state, and the operation controller 21 of the control unit starts operation (S11).

Therefore, the operation control unit 21 reads the signal output from the drive switch SW11 and judges whether the drive switch SW11 is in the operating state (S12, S13).

When the drive switch SW11 is in an operating state, the operation control unit 21 outputs a drive signal to the first and second solenoid valves 41 and 42 to operate the first and second solenoid valves 41 and 42 (S14).

The air pressure is applied to the first and second cylinders 412 and 422 through the first and second regulators 411 and 421 by the operation of the first and second solenoid valves 41 and 42, 2 cylinders 412 and 422 are in an operating state.

Accordingly, by the operation of the first cylinder 412, pressure is applied to the label conveying path (LAM) discharged from the label conveying roller unit 10 to prevent lifting of the label conveying path (LAM) The rollers R16 and R17 are brought into contact with the drive roller R15 by the operation of the drive roller R15 and the rollers R11 to R14 and R16 to R18 are rotated by the rotation of the drive roller R15 So that the movement of the label conveying path (LAM) provided in the label feeding device can be performed.

Next, the operation control unit 21 reads out the signal output from the label detection unit 12 and outputs a label LA (that is, a set amount (Label LA that has been peeled off from label label LB) is present (S15, S16).

When the label LA protruded from the end of the pedestal 701 of the label separator 70 by a predetermined amount is detected, the operation control unit 21 sets the label (label) attached to the label transfer destination (LAM) LA) is positioned.

Accordingly, the operation control unit 21 outputs a driving signal to the air emission driving unit 51 (S17), operates the air launching unit 50 to perform air injection in the upward direction, So that the label LA can be prevented from hitting downward.

Next, the operation control unit 21 transmits the label adsorber drive signal to the label adsorber 200 using the communication unit 23 (S18).

When the label adsorber driving signal transmitted from the label supply device is transmitted, the label adsorber 200 moves to the setting position for the adsorption operation of the label LA located on the pedestal 701 by the predetermined operation, (LA), and the label LA located on the pedestal 701 is adsorbed by the air suction operation.

When the suction operation of the label LA located on the pedestal 701 is completed, the label adsorber 200 transmits a label adsorption completion signal to the label supplier 21.

To this end, the label adsorber 200 also has a separate communication unit for communicating with the communication unit 23.

The operation control unit 21 of the label supply apparatus transmits a label adsorber driving signal to the label adsorber 200 and then determines whether a label adsorption completion signal is received from the label adsorber 200 through the communication unit 23 S19).

If the label adsorption completion signal is not received from the label adsorber 200, the operation control unit 21 proceeds to step S19 and determines whether or not the label adsorption completion signal is received from the label adsorber 200. [

When the label adsorption completion signal is received from the label adsorber 200, the operation control unit 21 performs the operation of peeling the label LA from the label backing LB.

Accordingly, the operation control unit 21 outputs the drive signal for the first state (e.g., reverse state) to the first motor M11 for a predetermined time (S110), and the first motor M11 rotates in the predetermined direction It is determined whether or not the label separator 70 has been moved backward by a predetermined amount along the label separator moving section 71 (that is, the amount of separation of the label LA absorbed by the label adsorber 200) , The operation controller 21 stops outputting the driving signal output to the first motor M11 for the backward movement of the label separator 70 when the label separator 70 is backward by a predetermined amount at step S112.

The main body 702 and the pedestal 701 are also moved backward by the backward movement of the label retractor 70 so that the label backrest LB caught by the end of the pedestal 701 is moved by the backward amount of the pedestal 701 do.

Since the roller R11 of the label feed roller unit 10 is not rotated when the label backing LB is moved backward, the label LA, which is held by the label adsorber 200 and is fixed in position, And is peeled from the label backing LB. At this time, the amount of peeling of the label LA is determined in accordance with the posterior extent of the label backing LB (that is, the backward amount of the label reversing device 70).

As described above, when the label LA is peeled off from the label backing LB, since the label LA to be peeled off in the present state is already adsorbed by the label adsorber 200, the peeling of the peeled label LA And the air LA 50 is already operated before the label peeling operation is performed, the label LA on which the fogging phenomenon occurs is further reduced by the air blown toward the contact surface.

In this example, the backward amount of the label separator 70 is controlled by using the application time of the driving signal applied to the first motor M11. Alternatively, the label separator 70 Can be controlled.

In this case, the operation control unit 21 determines the backward amount of the label separator 70 using the sensing signal applied from the sensing unit, and when the determined backward amount reaches the set amount, The output of the signal is stopped.

When the peeling operation of the label LA adsorbed on the label adsorber 200 is completed, the operation control unit 20 transmits a pick-up start signal to the label adsorber 200 using the communication unit 23 (S113).

When the pick-up start signal is transmitted from the label feeder to the label adsorber 200, the label adsorber 200 performs a control operation to move the corresponding label LA adsorbed through the vertical movement operation and the horizontal movement to a position And the operation of attaching the label LA to the corresponding position of the moved product is performed.

The label adsorber 200 then sends a pickup completion signal to the label feeder.

Therefore, the operation control unit 21 outputs a pickup start signal, and then determines whether a pickup completion signal is received from the label adsorber 200 through the communication unit 23 (S114).

When the pick-up completion signal is received from the label adsorber 200, the operation control unit 21 controls the state of the drive signal applied to the air firing drive unit 51 since the peeling operation for one label LA is completed The operation of the air launching unit 50 is stopped until the next label LA is moved to the set position (S115).

Next, the operation control unit 21 outputs the drive signal for the second state (e.g., forward state) to the first motor M11 for a predetermined time (S116-S118), and sets the position of the label separator 70 to the initial state .

The label separator 70 advances by a predetermined amount along the label separator moving section 71 by the operation of the first motor M11 so that a part of the pedestal 70 as an initial position is advanced to the air launching section 50 Lt; / RTI > As a result, an initial state for separating operation of the next label LA is obtained.

Also in this case, the advance amount of the label separator 70 is controlled by using the application time of the drive signal applied to the first motor M11. Alternatively, the advance amount of the label separator 70 The operation control unit 21 determines the advance amount of the label separator 70 by using the sensing signal applied from the sensing unit, and when the determined forward amount reaches the set amount, the first motor M11 The output of the driving signal is stopped.

The operation controller 21 outputs the drive signal to the second motor M12 in step S119 and the roller R19 connected to the second motor M12, In the corresponding direction.

By the rotation operation of the roller R19, the drive roller R15 and the label fog roller R20 rotate in the corresponding directions by the timing belts T11 and T12.

Accordingly, the remaining rollers R16, R17 and R11 to R14 are rotated in the corresponding directions as shown in FIG. 3 in accordance with the rotation of the rollers R15 and R20, The label conveying path LAM is loosened and moved along the label conveying path guide 60 toward the label fingering roller portion 20 to be wound on the label fingering roller portion 20. [

The label LA to be sucked after being attached to the label transfer destination LAM by the movement of the label transfer sheet LAM is transferred to the label detection unit 12 via the support 701 of the label separator 70 To the position to be detected.

Therefore, after the drive signal is output to the second motor M12, the operation control unit 21 proceeds to step S15 and moves to the setting position for the label suction operation by the movement of the label transfer destination (LAM) ) Is moved, and the above-described label suction operation is repeated.

The operation control unit 21 reads out the signal from the pressure release switch SW12 and outputs the signal to the pressure release switch SW12. Then, the process goes to step S13, and when the determined state of the drive switch SW11 is in the non- (S120, S121).

When it is determined that the pressure release switch SW12 is operated, the operation control unit 21 stops the output of the drive signals applied to the first and second solenoid valves 41 and 42 and outputs the first and second solenoid valves 41, and 42 to a non-operating state (S122).

As the first and second solenoid valves 41 and 42 are changed from the operating state to the non-operating state, the air pressure applied to the first and second cylinders 412 and 422 is released, And the rollers R16 and R17 in contact with the drive roller R15 move to a position spaced apart from the drive roller R15 and the contact state of the drive roller R15 is released.

Therefore, the rotation of the rollers R11-R14 and R16-R18 is stopped and the pressure applied to the label backing LB located between the drive roller R15 and the rollers R16, R17, which are in contact with each other, The label transferring paper (LAM) provided in the supplying device and the label transferring paper (LB) continuous to the label transferring paper (LAM) can be manually released.

As a result, a new label feeding destination (LAM) can be mounted on the label feeding device according to the needs of the operator.

Next, with reference to Fig. 6, the operation of the operation control unit 21 for determining whether or not the label feeder (LAM) and the label fur LB are normally installed in the label feeder will be described.

This operation can be performed in a routine separate from the label peeling operation described with reference to Figs. 5A and 5B.

When the operation of the operation control unit 21 is started (S20), the operation control unit 21 reads the signal outputted from the label conveying sheet detection unit 11 (S21) and determines whether the label transfer destination (LAM) (S22).

If it is determined that the label transfer destination (LAM) is detected at the corresponding position, the operation control unit 21 determines whether the label transfer destination (LAM) normally wound on the label transfer destination roller unit 10 is the label transfer destination guide It is judged that it is being discharged.

Accordingly, the operation control unit 21 reads the signal output from the label backing sensing unit 13 (S23).

However, when no label transfer destination (LAM) is detected at the corresponding position, the operation control unit 21 disconnects the label transfer destination (LAM) wound around the label transfer destination roller unit 10 and normally transfers the label transfer destination guide 60 The operation control unit 21 outputs a driving signal to the warning unit 31 to operate the warning unit 31 in operation S24 and then outputs the driving signal to the warning unit 31 The detection signal is read (S23).

Next, the operation control unit 21 determines whether there is a label backing LB at the corresponding position by the output signal of the label backing sensing unit 12 (S24).

The operation control unit 21 determines that the label backing LB having the label LA peeled off is normally wound on the label fringe roller unit 20 and returns to the returning step S200) and goes to the first operation.

 However, when the label furrow LB is not detected at the position, the operation control unit 21 determines that the label furrow LB is cut off and the winding operation to the conveying paper furrow roller unit 20 is not normally performed .

Accordingly, the operation control unit 21 outputs a driving signal to the warning unit 31 to operate the warning unit 31 (S25).

In this way, when at least one of the label transfer destination LAM and the label transfer LB is disconnected, the warning unit 31 operates. Therefore, the administrator can use the operating state of the warning unit 31 to normally It is judged whether or not the label conveying paper LAM or the label backing paper LB is attached. If the label conveying paper LAM or the label backing LB is broken, a necessary action is taken promptly.
