Description

The present invention relates to a label issuing device.

In consideration of the environment, so-called mount-less labels are used, in which a backing paper (release paper) is not attached to the label sticking surface, which can suppress dust generated when the label is issued. In a label issuing device that uses such a mount-less label, the nip pressure between a printing portion such as a thermal head that prints on the label and a pressing portion such as a platen roller that presses the mount-less label against the printing portion is used. , The adhesive surface of the mount-less label and the pressing portion may be firmly fixed. Such sticking may cause a problem such as the mountless label wrapping around the pressing portion.

A label issuing device that solves such a problem is disclosed in Patent Document 1. The label issuing device of Patent Document 1 is arranged between a printing means composed of a thermal head and a platen roller, a transporting means arranged upstream of the printing means in the transport direction, and the printing means and the transporting means. It has a detecting means for detecting the mount-less label and a control means for controlling the transporting means. When the detecting means detects the mount-less label, the control means attaches the tip of the mount-less label to a thermal head and a platen roller. The transport means is controlled so as to stand by on the upstream side of the region to be pressed by the predetermined nip width and above the platen roller. This prevents the mountless label and the platen roller from being firmly fixed.

Japanese Unexamined Patent Publication No. 2017-149161

However, in the conventional label issuing device, every time the detecting means detects a mountless label, that is, every time a label is issued (a cutting means such as a cutter provided on the downstream side of the printing means cuts the printed portion). , Since it is necessary to feed back the mount-less label, the control becomes complicated. Therefore, there is room for improvement in the method of controlling the transport means for fixing the mount-less label to the platen roller as described above.

Therefore, an object of the present invention is to provide a label issuing device capable of preventing the mountless label from sticking to the pressing portion due to the nip pressure between the printing portion and the pressing portion.

The label issuing device of the present invention prints on a strip-shaped mountless label having an adhesive surface formed on one surface and a printing surface formed on the other surface, and issues the printed portion as a printing label. An issuing device, a delivery unit that conveys the mount-less label along the feeding path of the mount-less label in the first direction and the second direction opposite to the first direction, and a printing unit that prints on the printing surface. Operate ON / OFF of the power supply, the pressing part that presses from the adhesive side to press the printing surface against the printing part, the cutting part that cuts the printed part of the mount-less label as the printing label from the mount-less label. When the operation unit and the operation unit that turns off the power are detected, the transmission unit is controlled so that the tip portion in the feeding direction of the mount-less label is on the second direction side of the pressing region on the printing portion by the pressing unit. It is provided with a control unit that turns off the power after giving feedback so that it is located at.

In the label issuing device having this configuration, when the control unit detects the operation of turning off the power, the tip of the mountless label is fed back to the second direction side in the feeding direction (upstream side from the pressing area in the feeding direction). After that, the power is turned off. In the label issuing device having this configuration, the control of the sending unit becomes simpler than in the case where the feedback as described above is executed each time a printed label is issued. Further, in the label issuing device having this configuration, since the power is prevented from being turned off while the backing sheet-less label is pressed by the pressing part on the printing part, the backing sheet-less label is pressed on the printing part by the pressing part for a long time. It is avoided to be in a pressed state. As a result, it is possible to prevent the backing sheet-less label from sticking to the pressing portion due to the nip pressure between the printing portion and the pressing portion.

In the label issuing device of the present invention, when the distance between the cutting portion along the feeding path of the mount-less label and the upstream end portion of the pressing region is the first distance, the control unit turns off the power in the operating unit. When the operation is detected, the sending unit may be controlled to feed back the mount-less label for a length equal to the first distance, and then the power may be turned off. In the label issuing device having this configuration, when the operation of turning off the power is performed, the tip portion in the feeding direction of the label can be reliably positioned on the upstream side in the feeding direction from the pressing region.

In the label issuing apparatus of the present invention, the feeding path of the mount-less label may be formed along the vertical direction. As a result, the printed label can be issued upward in the vertical direction.

In the label issuing device of the present invention, the pressing portion is a roller, and the sending portion may be formed by a printing portion that sandwiches the mountless label between the rollers and a driving portion that rotates the rollers. .. In this configuration, in a label issuing device in which the pressing unit also serves as a sending unit, the printing efficiency of the printing label and the pressing unit is not reduced, and the nip pressure between the printing unit and the pressing unit is applied to the pressing unit. It is possible to prevent the backing sheet-less label from sticking.

The label issuing device of the present invention may be further provided with a support portion which is arranged on the second direction side of the pressing region in the feeding path and supports the tip end portion of the mountless label. In this configuration, the tip of the backing sheet-less label after feedback can be supported in the vicinity of the pressing area. Therefore, after the power is turned on, the process or work of pressing from the adhesive surface side to press the printing surface against the printing portion is performed. It can be easily implemented.

In the label issuing device of the present invention, the delivery unit may not be arranged on the second direction side of the pressing region in the feeding path. When a label is continuously issued in such a configuration, a work of manually pressing the label from the adhesive surface side to press the printed surface against the printed portion (hereinafter referred to as "preparatory work") is performed every time the label is issued. This is a heavy work load for the user. In the label issuing device having this configuration, it is not necessary to manually perform the preparatory work every time a label is issued, so that the work load when continuously issuing labels can be reduced.

In the label issuing device of the present invention, the support portion may have a function of feeding out the tip end portion of the mount-less label to the first direction side. In this configuration, the preparatory work after the power is turned on does not need to be manually executed and can be automatically executed.

According to the present invention, it is possible to prevent the mount-less label from sticking to the pressing portion due to the nip pressure between the printing portion and the pressing portion.

The control unit 70, which will be described in detail later, detects that the power supply operation unit 17 has been operated by detecting that the current has flowed.

The measuring unit 20 mainly includes a measuring table 21, a load cell (not shown), a signal processing circuit, and a transmission module. The load cell is provided below the measuring table 21, and converts the mechanical strain generated when the object to be measured is placed on the measuring table 21 into an electric signal. The signal processing circuit amplifies the electric signal output from the load cell and converts it into a digital signal. The transmission module transmits a digital signal to the control unit 70 in the main body case 3 wirelessly or by wire.

As shown in FIGS. 2 and 3, the printer unit 30 is arranged behind the opening / closing door 3A provided on the front right side of the main body case 3. The opening / closing door 3A is provided so as to be openable / closable by rotating around the lower end. The printer unit 30 is arranged so as to be exposed when the opening / closing door 3A is opened. The printer unit 30 includes a cassette unit 31, a printing unit (sending unit) 33, a cutter unit (cutting unit) 40, and a temporary attachment unit 50.

The cassette unit 31 detachably supports the label roll LR. A roll support portion R capable of supporting the label roll LR in a cantilever state is formed on the side wall 31A of the cassette portion 31, and the label roll LR is mounted on the roll support portion R.

Here, the label roll LR will be described. The label roll LR is formed by winding a strip-shaped mount-less label L around a paper tube to form a roll. In the mount-less label L (hereinafter, simply referred to as "label L"), an adhesive is applied to the back surface of the base paper, and a heat-sensitive agent that develops color by heat is applied to the front surface (printing surface). Silicone resin as a release agent is applied from above. The label roll LR is wound around a paper tube with the back surface (sticking surface) of the label L inside.

The cassette unit 31, the printing unit 33, the cutter unit (cutting unit) 40, and the temporary attachment unit 50 in the printer unit 30 form a feeding path P for the label L. The feeding path P of the present embodiment is formed from the lower side to the upper side in the vertical direction. The terms "upstream" and "downstream" used in the following description mean "upstream" and "downstream" in the feeding direction in which the label L is fed from the label roll LR in the feeding path P. Then, in the printer unit 30, the cassette unit 31, the printing unit 33, the cutter unit (cutting unit) 40, and the temporary attachment unit 50 are arranged in order from the upstream side along the feeding path P.

The printing unit 33 has a printing head (printing unit) 35 and a platen roller (pressing unit) 37. The print head 35 is provided on the back surface of the opening / closing door 3A, and prints product information on the front surface of the label L. The print head 35 is composed of a thermal type print head. The print head 35 is controlled by the control unit 70, which will be described in detail later. The print head 35 is positioned so as to be in contact with the platen roller 37 by closing the opening / closing door 3A. Specifically, the print head 35 is fixed to a support frame 35A attached so as to be close to and separated from the opening / closing door 3A via a hinge (not shown). Further, a spring 35B is provided between the support frame 35A and the opening / closing door 3A to urge the print head 35 against the platen roller 37 when the opening / closing door 3A is closed.

Further, the print head 35 extends not only to the portion sandwiching the label L with the platen roller 37 described in detail later, but also to the upstream side (second direction side) along the feeding path P. As a result, the tip end portion of the label L that is fed out from the upstream side can be guided. The tip of the label L means the tip in the feeding direction A, which will be described later. Hereinafter, it is simply referred to as the tip portion of the label L.

The platen roller 37 is arranged so as to face the position of the print head 35 when the opening / closing door 3A is closed. The platen roller 37 presses from the back surface side of the label L to press the front surface of the label L against the print head 35. A gear mechanism (not shown) for driving the platen roller 37 is incorporated in the side wall 31A of the cassette portion 31. When the cassette portion 31 is mounted on the mounting portion 3B of the main body case 3, the gear mechanism is connected to the drive motor (drive portion) 38 and the platen roller 37 is rotationally driven. The platen roller 37 is a drive roller driven by a drive motor 38. The peripheral surface of the platen roller 37 is formed in an uneven shape in order to reduce the contact area of the label L with the sticking surface.

The drive motor 38 is controlled by the control unit 70, which will be described in detail later. When the platen roller 37 is rotationally driven with the label L sandwiched between the print head 35 and the platen roller 37, the label L is fed out from the label roll LR along the feeding path P (first direction) A. And, it is conveyed in the rewinding direction (second direction) B opposite to the feeding direction A. In this embodiment, the sending unit for feeding out the label L is not provided on the upstream side of the printing unit 33. In other words, the label L is not fed in the feeding direction A unless it is sandwiched between the print head 35 and the platen roller 37.

A first guide plate 39A that regulates the feeding path P of the printed label L is attached above the platen roller 37. A second guide plate 39B that regulates the feeding path P of the printed label L is attached above the print head 35 (the tip of the support frame 35A on the opening / closing door 3A side). The first guide plate 39A and the second guide plate 39B are arranged so as to face each other (opposite the letter "H") so as to gradually narrow in the direction in which the label L is sent out when the opening / closing door 3A is closed. Has been done. The label L is sent out from the tip portion where the gap between the first guide plate 39A and the second guide plate 39B is narrowed.

The cutter unit 40 separates the label L sent out from the printing unit 33 as a printing label LC (see FIG. 1) having a predetermined length. That is, the cutter unit 40 cuts out the portion of the label L printed by the print head 35 as the print label LC. The cutter unit 40 is attached to the upper part of the pair of the first guide plate 39A and the second guide plate 39B and the platen roller 37. Further, the cutter unit 40 is attached to the upper part of the main body case 3. The cutter unit 40 includes a fixed blade 41 and a movable blade 43. In the cutter unit 40, the movable blade 43 is connected to the crank mechanism inside the cutter unit 40 and reciprocates in the horizontal direction with the fixed blade 41 at high speed.

The temporary attachment portion 50 mainly includes a pressing member 51 that lightly presses the label L against the surface thereof, and a holding roller 53. The pressing member 51 is a member arranged to lightly press the printed label L against the holding roller 53, and is formed of a thin resin plate. The peripheral surface of the holding roller 53 is formed in an uneven shape in order to reduce the contact area of the label L with the sticking surface.

The temporary attachment portion 50 holds the label L from the front and back when the print label LC is separated from the label L by the cutter unit 40. Further, the temporary attachment portion 50 holds the print label LC separated from the cutter unit 40 from the front and back, and the rear end portion (upstream end portion in the feeding path P) of the print label LC is subsequently sent out from the label L. It is retracted to a position where it does not come into contact with the front end portion (downstream end portion in the feeding path P), and the tip end portion of the subsequent label L is joined to the adhesive surface of the preceding printed label LC. In the temporary attachment portion 50, the print label LC cut one by one is laminated one after another on the rear end portion of the preceding print label LC, and a label sheet LS in a state of being connected in a sheet shape is formed.

The control unit 70 is a part that controls various operations in the electronic scale 1, and the CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory) use bus lines such as an address bus and a data bus. They are connected to each other via. As shown in FIG. 4, the control unit 70 executes various control processes in the electronic scale 1. The control unit 70 can be configured as software in which a program stored in the ROM is loaded on the RAM and executed by the CPU, for example. The control unit 70 may be configured as hardware such as an electronic circuit.

The control unit 70 receives, for example, a digital signal transmitted from the measuring unit 20, or multiplies the mass obtained from the received signal by a preset unit price per unit mass to calculate the price. The price is displayed on the touch panel 13 of the clerk side operation unit 11 and the liquid crystal display of the customer side operation unit.

Further, the control unit 70 controls various operations in the printer unit 30. When the control unit 70 detects that the power supply operation unit 17 has performed an operation to turn off the power, the tip portion of the label L is on the upstream side (cassette unit 31) of the pressing region PA on the print head 35 by the platen roller 37. After giving feedback so that it is located on the side), turn off the power. Note that turning off the power supply here means cutting off at least the power supply to the drive motor 38. The drive motor 38 whose electricity supply is cut off cannot be driven, nor can the platen roller 37 be rotated. If the power is turned off while the label L is sandwiched between the print head 35 and the platen roller 37, the label L is left in a state of being pressed by the print head 35 and the platen roller 37.

Next, the operation of the printer unit 30 of this embodiment will be described. For example, when the user operates the "print" key, the platen roller 37 rotates in the reverse direction to retract the label L sent out to the position of the cutter unit 40 (move in the rewinding direction B), and the tip of the label L Is returned to the position of the print head 35. Subsequently, the print head 35 prints the weight, price, product information, and the like on the label L sent out in the feeding direction A by rotating the platen roller 37 in the forward direction in a predetermined format.

The label L is sent out while the product information is printed by the print head 35 and the platen roller 37. In other words, the printing unit 33 is a portion that serves both for printing and sending the label L. The label L on which the product information is printed is cut by the cutter unit 40 with the front and back surfaces held by the temporary attachment portion 50 to become the printed label LC. The front and back sides of the printed label LC separated from the label L are held by the temporary attachment portion 50.

The temporary attachment portion 50 lightly holds the front and back surfaces of the preceding print label LC by the pressing member 51 and the holding roller 53, and the rear end portion of the preceding print label LC does not hinder the progress of the front end portion of the subsequent label L. As described above, the preceding print label LC is held in the forward leaning posture or the forward leaning posture. That is, since the contact position between the holding member 51 and the holding roller 53 is set to a position slightly inclined forward or backward from the rotation center of the holding roller 53, the preceding printed label LC is set to a position where the holding member 51 and the holding roller 53 are tilted. When held between and, the rear end portion of the preceding print label LC separates from the feeding path P and moves to a position that does not hinder the progress of the succeeding label L sent out later.

The cut print label LC is held by the temporary attachment portion 50 with its rear end separated from the feeding path P, and when the tip end of the subsequent label L touches the adhesive surface of the preceding print label LC, a time point Both labels are joined at. The print label LC cut into pieces by repeating such an operation one after another is laminated one after another on the rear end portion of the preceding print label LC, and the label sheet LS in a state of being connected in a sheet shape is formed. It is formed.

The label L separated from the preceding print label LC is pulled back to the position of the print head 35 by the reverse rotation of the platen roller 37, and then printed while being sent out again by the forward rotation. Then, when the position at the rear end of the next printed label LC reaches the cutter unit 40, the feeding of the label L is stopped at that moment, and then the cutter unit 40 operates to cut the label L. In this way, the label L is once pulled back, sent out, and printed.

Next, the operation of the electronic scale 1 when the power supply operation unit 17 is operated will be described. When the user operates the power supply operation unit 17, the control unit 70 detects that the power supply operation unit 17 has been operated. The control unit 70 that has detected that the power supply operation unit 17 has been operated feeds back so that the tip of the label L in the feeding direction is located closer to the cassette unit 31 than the pressing region PA on the print head 35 by the platen roller 37. After that, turn off the power. Specifically, when the distance between the cutter unit 40 along the feeding path P of the label L and the upstream end portion in the feeding direction of the pressing region PA is the first distance L1, the control unit 70 is the power supply operating unit 17. When it is detected that the power is turned off, the label L is fed back by a length equal to the first distance L1 (pulled back in the rewinding direction B), and then the power is turned off. The tip of the label L fed back as described above is in a state of being supported from diagonally below by the print head 35.

Next, when the user uses the electronic scale 1, the user operates the power supply operation unit 17. The control unit 70 that has detected that the power supply operation unit 17 has been operated is in a state where electricity is supplied to the drive motor 38. When the power is turned on, the tip of the label L is always located upstream of the printing unit 33. That is, the label L is not sandwiched between the print head 35 and the platen roller 37. In the present embodiment, the sending unit for feeding out the label L is not arranged on the upstream side of the printing unit 33. Therefore, the user sets the tip of the label L between the print head 35 and the platen roller 37 (setup work). The setup work may be performed before the power is turned on. By such an operation, the electronic scale 1 is ready to issue the print label LC.

Next, the action and effect of the electronic scale 1 including the printer unit 30 of the above embodiment will be described. In the electronic scale 1 of the above embodiment, when the control unit 70 detects that the power is turned off, the tip of the label L is on the rewinding direction B side (upstream side from the pressing region PA) along the feeding path P. The power is turned off after feeding back the part. In the electronic scale 1 of the above embodiment, the control of the printing unit 33 becomes simpler than the case where the feedback as described above is executed every time the printing label LC is issued. Further, in the electronic scale 1 of the above embodiment, since the power is prevented from being turned off while the label L is pressed against the print head 35 by the platen roller 37, the label L is printed by the platen roller 37 for a long time. It is avoided that the head 35 is pressed against the head 35. As a result, it is possible to prevent the label L from sticking to the platen roller 37 due to the nip pressure between the print head 35 and the platen roller 37.

Further, in the electronic scale 1 of the above embodiment, the time required for continuously issuing the print label LC is shortened as compared with the case where the above feedback is executed every time the print label LC is issued. be able to. As a result, it is possible to prevent the label L from sticking to the platen roller 37 due to the nip pressure between the print head 35 and the platen roller 37 without reducing the issuing efficiency when the print label LC is continuously issued.

In the above embodiment, when the control unit detects that the power is turned off in the operation unit, the label L is displayed at the distance between the printing unit 33 along the feeding path P and the upstream end portion of the pressing region PA. After feeding back a length equal to a certain first distance L1, the power is turned off. In the electronic scale 1 of the above embodiment, when there is no printing command for the next label, the printing label LC is stopped in a state where the printing label LC is issued, that is, a printing label LC is cut from the tip end portion of the label L. Therefore, unless the label L is stopped during printing for some reason, if the label L is fed back by the first distance L1, the tip end portion of the label L can be reliably positioned upstream of the printing unit 33. As a result, in the electronic scale 1 of the above embodiment, when the power is turned off, the tip of the label L can be reliably positioned upstream of the pressing region PA in the feeding path P. ..

In the above embodiment, since the feeding path P of the label L is formed along the vertical direction, the entire device can be formed compactly.

In the above embodiment, even if the platen roller 37 also serves as a delivery unit, the nip pressure between the print head 35 and the platen roller 37 is used without reducing the issuing efficiency when continuously issuing the print label LC. It is possible to prevent the label L from sticking to the platen roller 37.

In the above embodiment, a part of the print head 35 supports the tip end portion of the label L on the rewinding direction B side (upstream side) of the pressing region PA in the feeding path P. As a result, the tip of the label L fed back as described above can be supported in the vicinity of the pressing region PA, so that the setup work of setting the label on the printing unit 33 can be easily executed after the power is turned on. it can.

In the above embodiment, the delivery unit for feeding the label L is not arranged on the rewinding direction B side (upstream side) of the pressing region PA in the feeding path P. In such a configuration, in the conventional configuration in which the tip end portion of the label L is fed back each time the print label LC is issued, the above setup work must be manually performed every time the print label LC is issued, and the user must perform the above setup work. It will be a heavy work load for. In the electronic scale 1 having this configuration, since the above feedback control is performed only when the power is turned off, the work load when continuously issuing the print label LC can be reduced.

Further, in the configuration in which the delivery portion for feeding the label L is not arranged on the rewinding direction B side (upstream side) of the pressing area PA, it is not necessary to separately arrange the motor, gear, belt, etc., so that the device is compactly formed. be able to. Further, by unifying the drive system as in the above embodiment, it is not necessary to consider the synchronization control, the tension control, and the like when feeding out the label L, so that simple control becomes possible.

Although one embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention.

In the above embodiment, an example in which the feeding path P of the label L is formed along the vertical direction has been described, but as shown in FIG. 5, it may be formed along the horizontal direction. At this time, a support portion 61 that supports the tip end portion of the label L that is fed back when the power is turned off may be arranged on the upstream side of the pressing region PA of the printing unit 33 in the feeding path P.

In the printer unit 30 according to the above embodiment and the modified example, the printing unit 33 having a configuration that also serves as a printing unit and a transmitting unit of the label L has been described as an example, but instead of this configuration, it is shown in FIG. As described above, the rollers 63A and 63B as the delivery unit may be provided on the upstream side (second direction side) of the printing unit 33 in the feeding path P. One of the roller pairs 63A and 63B is a drive roller driven by the drive motor 65. The drive motor 65 is driven by the control unit 70. In this configuration, the tip of the label L, which is fed back when the power is turned off, can be automatically sent to the printing unit 33 when the power is turned on. As a result, the user can omit the setup work at the time of turning on the power.
