However, for example, when trays are transported one after another in a short period of time, it takes time to issue labels and transport labels, so it is not possible to apply labels to the trays in time for label application to the tray. There is a fear.

  In addition, for example, in a lower-pasting device having a mechanism for temporarily stopping the label transport by the label transport conveyor and restarting the label transport by the label transport conveyor at the pasting timing, the transport is continuously performed in a short time. In some cases, it is difficult to attach a label to an object to be applied.

The printing apparatus 400 and the pasting apparatus 100 according to the embodiment of the present invention perform printing on the next recording paper and do not perform cutting by the cutting unit in a state where the label stays in the staying part that stays the label at the pasting standby position. If the label detection unit detects that the label is not staying in the staying part (when label is attached or after labeling), it is in a standby state for the recording paper printed by the printing means Cutting operation is performed by the cutting means. A label cut into a single sheet is conveyed to a sticking standby position by a label conveying unit.
That is, a sticking device having a printing device sticks labels on a sticking object that is successively conveyed in a short time with a short sticking time interval with high efficiency.

  Next, an example of the operation of the printing apparatus 400 and the pasting apparatus 100 according to the embodiment of the present invention will be described in detail with reference to the drawings. The printing apparatus 400 and the pasting apparatus 100 have an automatic pasting mode and a manual pasting mode regarding labels. The automatic pasting mode has a normal pasting mode and a high speed pasting mode. The operation in the automatic pasting mode will be described.

  FIG. 9 is a flowchart illustrating an example of operations of the printing apparatus 400 and the pasting apparatus 100. In the present embodiment, the control unit constantly drives and controls the label transport conveyor of the label transport unit at a predetermined speed.

In other words, it is assumed that the label is in the staying state at the staying position if the label is being transported by the label transporting unit.

In step S4, the control unit 31 determines whether or not it is the high-speed application mode, and proceeds to the process of step S6 in the case of the high-speed application mode, and proceeds to the process of step S5 in the case of the normal application mode instead of the high-speed application mode.
Note that the control unit, for example, determines the high-speed application mode when the transfer time interval of the objects to be transferred successively is shorter than a predetermined time, and determines that the normal application mode is otherwise. Also good.
In addition, for example, the control unit determines that the high-speed application mode is received when a signal specifying the high-speed application mode is received from the operation input unit, and determines that the normal application mode is selected when a signal specifying the normal application mode is received. Also good.

  In step S5, in the normal pasting mode, the control unit performs a process of pasting the label on the lower surface of the object to be pasted such as the tray T (see FIG. 12), and proceeds to the process of step S1. Specifically, in the normal sticking mode, the control unit adjusts the label issuance timing in accordance with the transport of the object to be pasted such as a tray, and drives the label transporting unit (label transporting conveyor, etc.), step S1. Proceed to the process.

  In step S6, the control unit performs a process of printing the print data of the next label on the continuous sheet fed from the label roll by the printing unit, and performs a process of waiting without cutting the sheet by the cutting unit. (See FIG. 13). In this case, although the endless belt of the label conveying unit 521 is rotated by a driving unit (not shown), the printed continuous paper is not cut and stays without shifting to that position. That is, the endless belt idles with respect to continuous paper that is not cut.

  In step S7, the control unit determines whether or not the object to be pasted is conveyed. Specifically, the control unit determines the presence / absence of conveyance of the adherend based on a signal from a sensor that detects conveyance of the article such as the third detection sensor 55. Specifically, the control unit proceeds to the process of step S9 when the adherend is conveyed, and proceeds to the process of step S8 when the adherend is not conveyed.

  In step S8, the control unit determines whether or not the label stays in the storage unit based on the signal from the second detection sensor 54, and if so, proceeds to the process in step S7. Otherwise, the process proceeds to step S10.

  In step S9, the control unit performs a process of pasting the previous label on the lower surface of the object to be pasted, and proceeds to the process of step S8.

  In step S <b> 10, the control unit performs a process of cutting the continuous continuous paper that is in a state of printing the print data of the next label without being cut by the cutting unit.

  In step S11, the control unit performs a process of transporting the label to the stay position by a label transport unit such as a label transport conveyor, and then proceeds to the process of step S4.

As described above, the printing apparatus 400 according to the embodiment of the present invention includes the printing unit (printing unit 25) that prints on the recording paper (paper 21a) fed out from the roll-shaped continuous body (label roll 21), and the printing.

Specifically, after the leading end Lt of the label L conveyed by the label conveying unit 521 passes the position of the second detection sensor 54, the number of steps of the drive motor (in the case of a stepping motor) of the label conveying unit 521 is a predetermined number. Whether or not the number of steps has been reached, or whether or not a predetermined time has elapsed since the leading end Lt of the conveyed label L has passed the position of the second detection sensor 54, etc. The control unit performs control of conveyance.

  As described above, in the manual sticking mode, the label L is transported to the downstream side as compared with the automatic sticking mode, and the standby is performed at the article placement surface of the article transport unit 101 or in the vicinity thereof. The operator can easily take the label L, and the work efficiency can be improved.

<Affixing device provided with a plurality of discharge control means (conveyance instruction means) concerning the conveyance of the label>
FIG. 15 is a flowchart for explaining an example of an operation at the time of operation of a paper feed button (conveyance instruction unit) as a discharge control unit disposed at the upper part and the lower part. FIG. 16 is a conceptual diagram for explaining an example of the operation at the time of operating the paper feed buttons (conveyance instruction means) arranged at the upper part and the lower part.

  Next, an upper paper feed button and a lower paper feed button are provided, and when the paper feed button is operated, the label issued by the issuing unit is moved to a predetermined position in the label conveying unit, thereby maintaining the maintenance.

Specifically, the label transport unit (label transport unit 521) transports the label as a predetermined position to a position (predetermined position) where the label can be attached to the article.
That is, it is possible to provide a sticking device capable of transferring the label to a desired position by the discharge control means.
The sticking device 100 may be a label sticking device that sticks a label on an article (product), or may be a label sticking device.

Further, the above-described discharge control means includes an upper paper feed button 38u as a first discharge control means for instructing discharge of the fed label to a position facing one area, and a discharge instruction for a position facing the other area. 2 and a lower paper feed button 29 as a discharge control means.
In the embodiment described above, the position facing one area where the label is transferred in accordance with the discharge instruction of the first discharge control means (upper paper feed button 38u) is the sticking position where the label is stuck on the article (label sticking portion 524). It is a neighborhood. Further, the position facing the other area where the label is transferred by the discharge instruction of the second discharge control means (lower paper feed button 29) is arranged in the vicinity of the label discharge port (label issue port 28).
That is, a sticking apparatus having high maintainability can be provided by performing a paper feeding operation for transporting the label to a position corresponding to the arrangement position of the first discharge control means or the second discharge control means.

That is, the sticking apparatus 100 according to the embodiment of the present invention includes an article transport unit 101 that transports an article to a label sticking position. The first transport instruction means (upper paper feed button 38 u) is disposed above the article transport unit 101. The second transport instruction means (lower paper feed button 29) is arranged below the article transport unit 101.
Further, the predetermined position where the label is conveyed is defined on the downstream side of the label conveying unit 521 in accordance with the operation of the first conveying instruction means (upper paper feed button 38u). A position different from the predetermined position where the label is transported is defined on the upstream side of the label transport unit 521 in accordance with the operation of the second transport instruction means (lower paper feed button 29).
That is, when the first transport instruction unit disposed above the article transport unit 101 is operated, the control unit controls the drive of the label transport unit 521 so that the label is placed upstream of the label transport unit 521. When the second transport instruction means (lower paper feed button 29) that is transported and disposed below the article transport unit 101 is operated, the control unit drives and controls the label transport unit 521 to control the label transport unit 521. Since the label is transported to the downstream side, there is little useless movement of the operator, and the label can be easily removed by the operator.

When the first transport instruction unit is operated, the control unit performs a process of transporting the label L to the pasting position where the label L can be pasted on the article by the label transport unit 521. When the second transport instruction unit is operated, the control unit performs a process of transporting the label L to a position different from the predetermined position by the label transport unit 521.
That is, a sticking apparatus having high maintainability can be provided by performing a paper feed operation for transporting a label to a label standby position corresponding to the position of the transport instruction means on which the paper feed operation has been performed.

Moreover, the sticking apparatus which concerns on embodiment of this invention has the operation part 64 operated by the operator, and the roll-shaped continuous body attachment part 20 which attaches a roll-shaped continuous body (label roll 21). The first transport instruction means (upper paper feed button 38 u) is disposed in the operation unit 64, and the second transport instruction means (lower paper feed button 29) is disposed in the vicinity of the roll-like continuum attaching section 20.
For this reason, the operator can easily remove the label during maintenance.

  In the embodiment described above, when the first transport instruction means (upper paper feed button 38u) is operated, the label standby position is in the vicinity of the second detection sensor 54 as shown in FIG. However, the present invention is not limited to this mode. For example, as in the manual sticking mode shown in FIG. May stand by at the article placement surface of the article transport unit 101 or at a position in the vicinity thereof. The operator can easily remove the label.

FIG. 17 is a diagram illustrating an example of a mechanism of the feed roller 24 of the printing apparatus according to the embodiment of the present invention. Specifically, FIG. 17A is a diagram illustrating an example of an operation during normal rotation, and FIG. 17B is a diagram illustrating an example of an operation during back feed.
When the label waiting time on the platen roller elapses for a long time, the mountless label sticks to the platen with an adhesive. There is a case. In order to prevent the trouble that the label is caught, it is necessary to back feed the platen roller once and peel the label from the platen roller. In the printing apparatus, when the paper is back-fed, a large force may be required as compared to when the feed roller is rotated forward, such as when the label is attached to the platen roller. In this embodiment, during the forward rotation of the feed roller, the pressing portions of the rollers 24a and 24b are displaced so that the paper is not pressed or slightly pressed to reduce the load on the drive motor (not shown), and back feed The platen roller 25a and the roller 24b are driven to rotate by the drive motor while the paper is reliably pressed by the roller 24a and the roller 24b (during reverse rotation of the feed roller), so that the paper is relatively large in the back feed direction. The printing apparatus has a mechanism for conveying by force.
Hereinafter, the mechanism of the feed roller of the printing apparatus according to the embodiment of the present invention will be described in detail.

  The feed roller 24 of the feed roller mechanism is disposed on the downstream side of the roller 22, and is disposed on the upstream side of the thermal head 25b as a printing unit and the platen roller 25a. The feed roller 24 includes a roller 24a that is a driven roller and a roller 24b that is a drive roller. The feed roller 24 conveys the paper 21a fed from the label roll 21 in a predetermined direction.

  The roller 24b, which is a driving roller, is rotatably supported by a casing portion of the printing apparatus. The roller 24b is configured to be rotatable by a driving belt 254 that transmits a driving force from a driving motor (not shown). In this embodiment, the driving force from a driving motor (not shown) is transmitted to the platen roller 25a provided on the downstream side of the roller 24b via the driving belt 254. That is, the roller 24b and the platen roller 25a are configured to rotate in the normal direction or the reverse direction in synchronization.

  The feed roller mechanism includes a fixed member 242 fixed to a casing of the printing apparatus, an L-shaped movable member 243 that rotatably supports a roller 24a that is a driven roller, and an urging unit that urges the movable member 243. Have Specifically, at the end of the movable member 243 on the roller 24b side, a support portion 244 that rotatably supports the roller 24a that is a driven roller is provided at the tip that is bent toward the platen roller 25a. A receiving member 243b extending in the substantially paper feeding direction from the central portion of the standing portion 243a of the L-shaped movable member 243 is provided. The receiving member 243b is configured to be urged in the urging direction by the lower end portion 241a of the urging means 241.

A hole 243 h is provided in the standing portion 243 a of the movable member 243.
A support member 245 for playing the movable member 243 is provided on the standing portion 242 a of the fixed member 242. In the present embodiment, the support member 245 includes a small-diameter portion 245a having an outer diameter smaller than the inner diameter of the hole 243h of the movable member 243, and a large-diameter portion 245b having an outer diameter larger than the small-diameter portion 245a. The support member 245 is fixed to the standing portion 242a of the fixing member 242 with a screw 245c or the like.
That is, the movable member 243 is mounted on the standing portion 242a of the fixed member 242.

Further, the feed roller mechanism has a biasing means 241 such as a spring 2411 that biases the roller 24a as a driven roller toward the roller 24b as a driving roller.
In the present embodiment, the urging means 241 includes a columnar pressing member 2412 having a large diameter portion at the tip, and a coiled spring 2411 disposed on the outer peripheral side of the pressing member 2412. The spring 2411 is defined to have an inner diameter smaller than the outer diameter of the large-diameter portion 2412a of the pressing member 2412, and is configured to bias the large-diameter portion 2412a toward the roller 24b.

Next, an example of the operation of the feed roller will be described.
First, the case where the paper 21a is conveyed in the paper feeding direction will be described. In this case, the platen roller 25a and the roller 24b are rotated in the normal rotation direction by a drive motor (not shown), and deliver the paper 21a in the left direction shown in FIG.
In this case, as shown in FIG. 17A, the roller 24a as the driven roller is configured not to press or slightly press the roller 24b as the driving roller.

Specifically, in the example shown in FIG. 17A, the center 24ac of the roller 24a is located on the downstream side of the center 24bc of the roller 24b and a line passing through the contact 21bc of the roller 24b and the paper 21a. Specifically, the upper portion of the hole 243h of the movable member 243 and the upper end of the small diameter portion 245a of the support member 245 are in contact with each other, and the upper end portion of the standing portion 243a of the movable member 243 is the large diameter portion 245b of the support member 245. The lower end portion 242b of the standing portion 242a of the fixed member 242 and the standing portion 243a of the movable member 243 are in contact with each other.
The biasing force applied to the roller 24a by the biasing means 241 is restricted, and the roller 24a does not press the roller 24b or presses it slightly.
For this reason, in the forward rotation direction, the load for driving the platen roller 25a by the drive motor is small.

Next, an example of the operation of the feed roller will be described.
<Forward rotation direction>
First, the operation of the feed roller when the paper 21a is transported in the paper feed direction (forward rotation direction) will be described. In this case, the platen roller 25a and the roller 24b are rotated in the normal direction by a drive motor (not shown), and convey the paper 21a in the left direction shown in FIG.
In this case, as shown in FIG. 17A, the roller 24a as the driven roller is configured not to press or slightly press the roller 24b as the driving roller.

Specifically, in the example shown in FIG. 17A, the center 24ac of the roller 24a is located on the downstream side of the center 24bc of the roller 24b and a line passing through the contact 21bc of the roller 24b and the paper 21a. As shown in FIG. 17A, the standing portion 243a of the movable member 243 is inclined so that the lower portion is positioned on the downstream side of the upper portion.
Specifically, the upper portion of the hole 243h of the movable member 243 and the upper end of the small diameter portion 245a of the support member 245 are in contact with each other, and the upper end portion of the standing portion 243a of the movable member 243 is the large diameter portion 245b of the support member 245. The lower end portion 242b of the standing portion 242a of the fixed member 242 and the standing portion 243a of the movable member 243 are in contact with each other.
The biasing force applied to the roller 24a by the biasing means 241 is restricted, and the roller 24a does not press the roller 24b or presses it slightly.
For this reason, in the forward rotation direction, the load for driving the platen roller 25a by the drive motor is small.

<At back feed>
Next, the operation of the feed roller during back feed (conveying the paper 21a in the reverse direction) will be described. In this case, the platen roller 25a and the roller 24b are rotated in the reverse direction by a drive motor (not shown), and convey the paper 21a in the right direction shown in FIG. As shown in FIG. 17B, the roller 24a, which is a driven roller, is configured to press against the roller 24b, which is a driving roller.

Specifically, in the example shown in FIG. 17B, the center 24bc of the roller 24b, the contact 21bc of the roller 24b and the paper 21a, and the center 24ac of the roller 24a are arranged on a substantially straight line. By pressing the receiving member 243b of the movable member 243 by the biasing means 241, the roller 24a presses against the roller 24b.
Specifically, as shown in FIG. 17B, the upper end portion of the movable member 243 abuts on the upper portion of the standing portion 242a of the fixed member 242, and the vicinity of the center portion of the standing portion 243a of the movable member 243 is supported. By coming into contact with the large-diameter portion 245b of the member 245, the standing portion 243a of the movable member 243 is inclined so that the upper portion is positioned downstream of the lower portion. In this state, the roller 24a is pressed against the roller 24b by pressing the receiving member 243b of the movable member 243 by the biasing means 241.
For this reason, in the case of back feed (in the reverse direction), the platen roller 25a and the roller 24b are rotationally driven by the drive motor in a state where the roller 24a is pressed against the roller 24b. It can be back-fed. Specifically, for example, even when the paper 21a is stuck to the platen roller 25a, the paper 21a can be easily back-fed.

FIG. 18 is a view showing an example of a mechanism of a feed roller having a plurality of support members 245 (regulating members). Specifically, FIG. 18A is a diagram illustrating an example of the operation during the forward rotation direction, and FIG. 18B is a diagram illustrating an example of the operation during the back feed.
Differences between the example shown in FIG. 18 and the example shown in FIG. 17 will be described. In the example shown in FIG. 17, an L-shaped movable member 234 is mounted on the fixed member 242 by a plurality of support members 245 (regulating members).
By providing the two support members 245, it is possible to set the inclination of the movable member 234 at the time of back feed or forward rotation with high accuracy. In addition, maintenance of the movable member 234 is easy.

In addition, as shown in FIG. 17, the printing apparatus according to the embodiment of the present invention has a mechanism that presses the paper during back feed and releases the pressure during normal rotation. For this reason, even when the label is attached to the platen roller at the time of backfeeding the paper, the platen roller 25a and the roller 24b are driven to rotate by the drive motor while the paper is pressed by the feed roller. Can be conveyed with a relatively large force in the backfeed direction.
Further, when the feed roller is rotating in the forward direction, the load of the drive motor that rotationally drives the platen roller 25a and the roller 24b can be reduced by not pressing the sheet or slightly pressing the sheet.
