Description

  The present invention relates to a label issuing machine having a cutting means for cutting a continuous label body.

  2. Description of the Related Art As a label issuing machine that issues a label to be attached to a product or the like, a machine that uses a mountless label roll is known. The mount-less label roll is obtained by winding only a continuous strip-shaped label into a roll without using a mount. When using the mountless label roll, the label issuing machine cuts the leading end portion of the continuous label body with a cutter and issues the cut portion as a label. In the case of using the mountless label roll, resource saving can be achieved by omitting the mount as a discarded material.

  In this type of label issuing machine, since the cutter blade contacts the glue surface of the label continuum, the glue adheres to the cutter blade. If glue accumulates on the blade of the cutter, the continuous label cannot be cut well, so that conventionally it has been necessary to clean the cutter frequently.

  In order to solve this problem, Patent Document 1 discloses a technique in which a cutter blade is brought into contact with an oil impregnated body each time a continuous label body is cut by a cutter. According to the technique of this patent document 1, since oil adheres to the blade of the cutter every time it is cut, it becomes difficult for glue to adhere to the blade of the cutter, and therefore the frequency of cleaning the cutter can be reduced.

JP 2012-192958 A

  However, in the technique of Patent Document 1, when excessive oil adheres to the cutter blade, a large amount of oil adheres around the cut portion of the label continuum, for example, discoloration on the printing surface of the label. The quality of the label may be impaired so that a scale or stain may occur or the label may not be properly applied to the object.

  Then, this invention makes it a subject to suppress adhesion of the glue to the cutting | disconnection means which cut | disconnects a label continuous body, maintaining the quality of the label issued by a label issuing machine favorable.

The label issuing machine according to the present invention is:
An application means for applying oil to a cut portion of a continuous strip-shaped label having a paste surface;
Cutting means for cutting the cut portion to which oil has been applied.

  According to the label issuing machine of the present invention, the oil on the cut portion of the continuous label body is less likely to adhere to the cutting means by the glue on the cut surface of the cut portion. Therefore, the cleaning frequency of the cutting means can be reduced or the cutting means need not be cleaned.

  In addition, since oil is directly applied to the cut portion of the continuous label body, it is easier to adjust the amount of oil attached to the cut portion than in the configuration in which oil is applied to the cutting means as in the prior art described above. . Therefore, it is possible to prevent the deterioration of the label quality due to the excessive oil adhesion.

  The label issuing machine according to the present invention may further include an adjusting unit that adjusts the amount of oil applied to the cut portion by the applying unit.

  Here, “the amount of oil applied to the cut portion” includes the amount of oil applied to one cut portion and the total amount of oil applied to a plurality of cut portions.

  In this case, the amount of oil applied to the part to be cut of the label continuous body is adjusted by the adjusting means. Label quality deterioration and oil waste can be prevented.

When the label issuing machine according to the present invention includes the adjusting means,
The adjusting means controls the application means so that oil is applied to a part to be cut among a plurality of parts to be cut arranged at intervals in the length direction of the label continuum. Features.

  Thereby, when the continuous label body is cut by the cutting means a plurality of times, the oil application before cutting is not performed for each part to be cut, but for a part to be cut. By this control, the total amount of oil applied to the label continuous body is adjusted, so that an appropriate amount of oil can be adhered to the cutting means. Therefore, adhesion of glue to the cutting means, oil adhesion from the cutting means to the part to be cut, and waste of oil can be suppressed.

When the label issuing machine according to the present invention includes the adjusting means,
The label issuing machine may further comprise an oil supply means for supplying oil to the application means,
The adjusting means may control oil supply to the application means by the oil supply means.

  In this case, the amount of oil applied to each cut portion and / or the total amount of oil applied to the label continuum is adjusted by controlling the oil supply to the applying means. Therefore, it is possible to prevent excessive oil from being applied to the label continuum while suppressing adhesion of glue to the cutting means.

The label issuing method according to the present invention includes:
Apply oil to the part to be cut of a continuous strip of label with a glue surface,
By cutting the to-be-cut portion to which oil has been applied, the label is cut out from the label continuum and issued.

  According to the label issuing method according to the present invention, the oil on the cut portion of the label continuous body makes it difficult for the glue on the glue surface of the label continuous body to adhere to the cutting means for cutting the cut portion. . Therefore, the cleaning frequency of the cutting means can be reduced or the cutting means need not be cleaned.

  In addition, since oil is directly applied to the cut portion of the continuous label body, it is easier to adjust the amount of oil attached to the cut portion than in the configuration in which oil is applied to the cutting means as in the prior art described above. . Therefore, it is possible to prevent the deterioration of the label quality due to the excessive oil adhesion.

  According to the present invention, since oil is applied to the cut portion of the continuous label body, the glue on the cut surface of the cut portion becomes difficult to adhere to the cutting device, so that the cleaning frequency of the cutting device can be reduced. Or cleaning of the cutting means becomes unnecessary. In addition, since it is easier to adjust the amount of oil adhering to the part to be cut than when oil is applied to the cutting means, it is possible to prevent label quality deterioration due to excessive oil adhering.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

[Overall configuration of labeling device]
FIG. 1 shows a label sticking apparatus 1 equipped with a label issuing machine 8 according to this embodiment. In addition to the label issuing machine 8, the label sticking device 1 has a conveyor 4 that conveys the product G, and a label L that is issued by the label issuing machine 8 on the upper surface of the product G that is conveyed by the conveyor 4 (FIG. )) Is attached, an operation display unit 12 for performing a predetermined input operation and a predetermined display, and a rack 2 that supports the above components. A lower pasting mechanism (not shown) for pasting a label on the lower surface of the product G may be further provided below the conveyor 4.

[Conveyor]
The conveyor 4 is disposed so as to move the product G along a conveyance direction (D direction in the drawing) from the left to the right as viewed from the front side of the label sticking device 1. Although the conveyor 4 is comprised with an endless belt, for example, in this invention, the specific structure of the conveyor 4 is not specifically limited.

  A commodity passage sensor 110 is disposed in the vicinity of the conveyor 4. The commodity passage sensor 110 detects whether or not the commodity G on the conveyor 4 has passed through a predetermined position on the upstream side in the transport direction (D direction in the drawing) from the label attaching position by the label sticking machine 10. Although the kind of goods passage sensor 110 is not limited, For example, the optical goods passage sensor 110 which has a light emission part and a light-receiving part is used.

[Labeling machine]
The label applicator 10 is disposed above the conveyor 4. The label sticking machine 10 is a sticking block 50 that sucks the label L issued by the label issuing machine 8 on the lower surface, and a sticking that pushes the label L sucked on the lower surface of the suction block 50 from the upper side and sticks it on the upper surface of the product G. Arm 31 (see FIG. 7). However, in the present invention, the configuration of the label sticking machine 10 is not particularly limited as long as it has a function of receiving the label L issued by the label issuing machine 8 and sticking it to the upper surface of the product G.

[Operation display section]
The operation display unit 12 includes a display panel 13 and a stroke key unit 14. The display panel 13 is constituted by a touch panel, for example. However, the display panel 13 is not necessarily a touch panel. When the display panel 13 is a touch panel, the operation display unit 12 does not necessarily have the stroke key unit 14.

[Label issuing machine]
The label issuing machine 8 is disposed above the conveyor 4. Further, the label issuing machine 8 is disposed adjacent to the upstream side of the label sticking machine 10 with respect to the transport direction (D direction in the figure).

  As shown in FIG. 2, a so-called mountless label roll LR is used for the label issuing machine 8. The label roll LR is formed by winding a strip-shaped continuous label LC having a glue surface and a non-glue surface in a roll shape so that the glue surface faces inward. The non-glue surface of the label continuum LC is a printing surface that develops color when heat is applied.

  The label issuing machine 8 includes a support shaft 90 that supports the winding center portion of the label roll LR, and a plurality of guide rollers 99a, 99b, and 99c that guide an extended portion of the label continuous body LC extending from the outer peripheral portion of the label roll LR. The printing unit 91 that prints on the printing surface of the label continuum LC, the printing roller 92 that sandwiches the label continuum LC together with the printing unit 91, and the label continuum LC toward the label issuing port W in cooperation with the printing roller 92 And an assist roller 93 for feeding in, a cutting means 95 for cutting the label continuum LC, and a housing 120 for housing various components of the label issuing machine 8.

  In the following description, the direction in which the label continuum LC is fed from the label roll LR toward the label issuing port W is referred to as “label supply direction” (F direction in the figure).

  One end of the support shaft 90 is fixed to the housing 120, and the other end of the support shaft 90 is a free end. The label roll LR can be set in the label issuing machine 8 by inserting the winding center portion of the label roll LR into the support shaft 90.

  The printing unit 91 is a thermal head that includes a plurality of minute heating elements that are heated according to the printing data. By contacting the heated heating element with the printing surface of the label continuum LC, the thermal printing method is performed. Perform printing.

  The surface of the printing roller 92 is made of a rubber material. The printing roller 92 is a driving roller that is rotationally driven by a printing roller motor 96. For the printing roller motor 96, for example, a stepping motor is used.

  The printing roller 92 is disposed so as to sandwich the label continuous body LC together with the printing unit 91. Thereby, the printing roller 92 can move the label continuous body LC in the label supply direction (F direction in the figure) by rotating the printing roller 92 while pressing the printing surface of the label continuous body LC against the printing unit 91. . The printing roller 92 is disposed below the printing unit 91. Therefore, the label continuum LC is sent out to the label issuing port W in a posture in which the printing surface is the upper surface.

  The printing roller 92 can rotate in both forward and reverse directions. The “forward direction” here refers to the rotational direction in which the label continuous body LC is fed in the label supply direction (F direction in the figure), and the “reverse direction” refers to the direction opposite to the label supply direction. Indicates the direction of rotation.

  The surface of the assist roller 93 is made of a rubber material. The assist roller 93 is a drive roller that is rotationally driven by an assist roller motor 97. As the assist roller motor 97, for example, a stepping motor is used.

  The assist roller 93 is disposed upstream of the print roller 92 in the label supply direction (F direction in the figure). The assist roller 93 is disposed so as to sandwich the label continuous body LC together with the opposed driven roller 94. As with the printing roller 92, the assist roller 93 can rotate in both forward and reverse directions.

  When the print roller 92 and the assist roller 93 are rotationally driven in the forward direction, the label continuum LC is fed in the label supply direction (F direction in the figure), and the print roller 92 and the assist roller 93 are rotationally driven in the reverse direction. Thus, the label continuum LC is back-feeded in the direction opposite to the label supply direction (F direction in the figure).

  Since the printing roller 92 and the assist roller 93 are rotationally driven by different driving sources, the rotational speed of the printing roller 92 and the rotational speed of the assist roller 93 can be individually controlled. However, the present invention does not prevent the printing roller 92 and the assist roller 93 from being rotated by the same drive source.

  Between the assist roller 93 and the printing roller 92, the label continuum LC is guided by a guide roller 99c so as to be detoured downward. A label sensor 100 is disposed between the assist roller 93 and the print roller 92. The label sensor 100 is a sensor that detects whether or not a continuous label body LC exists between the assist roller 93 and the print roller 92. For the label sensor 100, for example, an optical sensor including a light emitting unit and a light receiving unit is used. In this case, the slack of the label continuum LC is detected based on the output value of the label sensor 100 using the fact that the output value of the label sensor 100 changes according to the distance between the label sensor 100 and the label continuum LC. Is possible.

  The cutting means 95 includes a movable cutter 95a and a fixed cutter 95b. The movable cutter 95a is disposed with the blade facing downward. The movable cutter 95a is driven to slide up and down by a cutter motor 98. The fixed cutter 95b is fixed to the housing 120 with the blade facing upward.

  When the cutting means 95 is not operating (standby state), the blade of the movable cutter 95a is disposed above the blade of the fixed cutter 95b. When the label continuous body LC is cut by the cutting means 95, the label continuous body LC is fed to the outside of the housing 120 through the label issuing port W, and the cut portion S (see FIG. 5) is fixed to the fixed cutter. The blade is aligned with the blade of 95b and the blade of the movable cutter 95a. If the movable cutter 95a is slid downward with the label continuum LC aligned as described above, the label continuum LC is sandwiched from above and below by the blade of the fixed cutter 95b and the blade of the movable cutter 95a. Is cut off. In this way, the label continuous body LC is cut by the cutting means 95, so that the label L cut from the label continuous body LC is issued from the label issuing port W.

[Coating equipment]
The label issuing machine 8 includes a coating device 70 that applies oil to the cut portion S of the label continuous body LC on the upstream side of the cutting means 95 in the label supply direction (F direction in the drawing). In FIG. 2, the illustration of the coating apparatus 70 is simplified, and a specific configuration of the coating apparatus 70 will be described later.

  The cut portion S of the label continuum LC is cut by the cutting means 95 in a state where the adhesive force is reduced by the oil applied by the coating device 70. Therefore, the glue of the label continuum LC hardly adheres to the blades of the movable cutter 95a and the fixed cutter 95b, and the cleaning frequency of the movable cutter 95a and the fixed cutter 95b can be reduced, or the cleaning of these is not necessary.

  With respect to the label supply direction (F direction in the figure), the position where oil is applied to the label continuum LC by the coating device 70 is preferably downstream of the nip portion between the printing unit 91 and the printing roller 92. . In this case, oil can be prevented from adhering to the printing unit 91 and the printing roller 92, and printing by the printing unit 91 can be performed satisfactorily.

[Specific example of configuration of coating apparatus]
Then, the specific example of a structure of the coating device 70 is demonstrated.

  In the example shown in FIG. 3, the coating apparatus 70 switches between a coating unit 72 that applies oil to the label continuum LC and a state in which the coating unit 72 is separated from and in contact with the label continuum LC. Device 74.

  In the portion where the coating device 70 is disposed, the label continuum LC is disposed along a substantially horizontal direction, and the lower surface of the label continuum LC is a glue surface.

  In the standby state of the coating device 70, the coating unit 72 is arranged to be spaced downward from the label continuum LC. The upper surface of the application part 72 is an application surface for applying oil to the label continuum LC. The part including at least the application surface in the application part 72 is made of a porous material such as a sponge, for example. The porous material of the application unit 72 is connected to the oil storage unit 80 via the oil supply path 81. The oil supply path 81 is provided with an oil pump 82 that supplies oil to the application unit 72.

  The switching device 74 is a drive device that slides the application unit 72 in a direction approaching and separating from the label continuum LC, that is, in the vertical direction. For example, a solenoid is used for the switching device 74. In a state where the oil supplied by the oil pump 82 is contained in the application part 72, the application part 72 is slid upward by the switching device 74, and the upper surface of the application part 72 is pushed against the glue surface of the label continuum LC. When applied, oil is applied to the glue surface.

  A receiving portion 76 is disposed above the label continuum LC with a slight gap. Thereby, when the application part 72 is pressed against the label continuous body LC, it is possible to suppress the label continuous body LC from being pulled upward by the application part 72. However, in the present invention, the receiving portion 76 may be omitted, and in this case, oil can be applied.

  FIG. 4 shows another example of the configuration of the coating apparatus 70. Also in the example shown in FIG. 4, the coating device 70 switches between a coating unit 172 that applies oil to the label continuum LC and a state in which the coating unit 72 is separated from and in contact with the label continuum LC. A switching device 174.

  In the example shown in FIG. 4, the application unit 172 is provided on the outer peripheral surface of the roller 170 disposed below the label continuum LC. With respect to the radial direction of the roller 170, the outer surface of the application part 172 is an application surface for applying oil to the label continuum LC. Similar to the example shown in FIG. 3, at least a part including the application surface in the application part 172 is made of a porous material. The porous material of the application unit 172 is connected to the oil storage unit 80 via the oil supply path 81, and oil is supplied by an oil pump 82 provided in the oil supply path 81.

  Furthermore, in the example shown in FIG. 4, the switching device 174 is configured by a motor that rotationally drives the roller 170. The switching device 174 can drive the roller 170 in the clockwise direction in the drawing. The application unit 172 is displaced in the circumferential direction by rotating together with the roller 170. When the application unit 172 is positioned at a predetermined position in the circumferential direction, the application surface of the application unit 172 is pressed against the glue surface of the label continuum LC, and oil is applied to the glue surface.

  At the contact portion between the coating unit 172 and the label continuum LC, the movement direction of the coating unit 172 and the movement direction (label supply direction) of the label continuum LC are the same direction (the right direction in FIG. 4). Even if the coating part 172 is pressed against the label continuum LC, the feeding of the label continuum LC is not hindered. The rotation speed of the roller 170 is preferably a speed at which the peripheral speed of the coating unit 172 rotating together with the roller 170 and the moving speed of the label continuum LC during feeding are approximately the same. Thereby, even if it contacts the application part 172, the feed of the label continuous body LC can be favorably continued.

  In each example shown in FIGS. 3 and 4, oil is applied to the glue surface of the label continuum LC by the application device 70. Therefore, the adhesive force of the glue surface of the label continuum LC is effectively reduced, so that adhesion of glue from the glue surface to the blades of the movable cutter 95a and the fixed cutter 95b can be effectively suppressed.

  The configuration of the coating apparatus 70 shown in FIGS. 3 and 4 is merely an example, and in the present invention, various configurations other than the configurations shown in FIGS. 3 and 4 may be adopted as the configuration of the coating apparatus 70. Is possible.

  For example, in order to enhance the effect of suppressing the adhesion of glue to the cutters 95a and 95b, the coating device 70 may be configured to apply oil to both the glue surface and the print surface of the label continuum LC. Further, from the viewpoint of completely maintaining the adhesive strength of the adhesive surface of the label continuum LC, the coating device 70 may be configured to apply oil only to the printing surface of the label continuum LC. When the coating device 70 capable of applying oil to the printing surface is configured, for example, an application unit similar to the application unit 72 shown in FIG. 3 or the application unit 172 shown in FIG. 4 may be disposed above the label continuum LC. . However, from the viewpoint of preventing discoloration, shine or stain on the printing surface, it is preferable to apply oil only to the glue surface.

  With reference to FIG. 5, a portion (a portion to be coated 200) where oil is applied by the coating device 70 in the label continuum LC will be described.

  The part to be coated 200 is a part along the part to be cut S in the label continuum LC. In the length direction of the label continuum LC, the width R of the coated part 200 is preferably, for example, 2 mm or more and 10 mm or less. The width R of the portion to be coated 200 can be set to a desired width by adjusting the contact width between the coating portions 72 and 172 of the coating device 70 and the label continuum LC. For example, in the example shown in FIG. 3, the width R of the application part 200 can be adjusted by appropriately changing the width of the application part 72. In the example shown in FIG. 4, the width of the application part 172 is changed as appropriate. Or by controlling the rotation speed of the roller 170, the width R of the portion to be coated 200 can be adjusted.

  Therefore, according to the present embodiment, an appropriate amount of oil can be applied to the label continuum LC by adjusting the width R of the portion to be coated 200 to a desired width.

[Control system]
The control system of the label sticking apparatus 1 will be described with reference to the block diagram shown in FIG.

  The control of the coating apparatus 70 will be mainly described in the case where the configuration of the coating apparatus 70 shown in FIG. 3 is adopted.

  Various operations of the label sticking apparatus 1 are controlled by the control unit 101. The control unit 101 is provided with a storage unit 102 that stores various information necessary for the operation of the label sticking apparatus 1. The control unit 101 is attached to, for example, the rack 2 (see FIG. 1), but the attachment position of the control unit 101 is not limited.

  The storage unit 102 stores, for example, various information including information regarding the screen displayed on the operation display unit 12, a product master, a tray master, a label master, and a cassette master. Various information stored in the storage unit 102 can be changed, added, or deleted by an input operation on the operation display unit 12.

  A signal from the operation display unit 12, a signal from the label sensor 100 of the label issuing machine 8, and a signal from the commodity passage sensor 110 are input to the control unit 101. Note that signals from other various devices may be input to the control unit 101. For example, in order to more precisely control the amount of oil applied to the label continuum LC, the amount of oil for detecting the amount of oil contained in the coating unit 72 (in the example shown in FIG. 4, the coating unit 172) in the coating device 70. When the sensor 130 is provided, a signal from the oil amount sensor 130 is input to the control unit 101. In this case, for example, a weight sensor is used as the oil amount sensor 130.

  Further, the control unit 101, based on the information stored in the storage unit 102 and / or various input signals, the thermal head 91, the printing roller motor 96, the assist roller motor 97 mounted on the label issuing machine 8. The control signal is output to the cutter motor 98, the switching device 74 of the coating device 70 (switching device 174 in the example shown in FIG. 4), and the oil pump 82 of the coating device 70. Further, the control unit 101 outputs control signals to various devices of the label sticking machine 10, the conveyor motor 104, and the operation display unit 12.

  The controller 101 controls the switching device 74 of the coating device 70 (switching device 174 in the example shown in FIG. 4) and the oil pump 82, whereby the oil applied to the cut portion S of the label continuum LC by the coating device 70. Adjust the coating amount.

  For example, the control unit 101 is applied to one cut portion S by controlling the oil pump 82 so as to adjust the amount of oil included in the application unit 72 (in the example shown in FIG. 4, the application unit 172). The amount of oil to be adjusted can be adjusted. By adjusting the amount of oil attached to the cut portion S by the control unit 101, the label L due to excessive oil application is avoided while preventing the glue from being easily attached to the cutters 95a and 95b due to insufficient oil application amount. Quality deterioration and oil waste can be prevented.

  In addition, when a plurality of labels L are issued and pasted continuously, the control unit 101 includes a part of the plurality of parts to be cut S existing at intervals in the length direction of the label continuum LC. By controlling the switching device 74 (in the example shown in FIG. 4, the switching device 174) so that oil is applied only to the cut portions S, the total amount of oil applied to the plurality of cut portions S is adjusted. be able to. In this case, for example, the oil application amount can be adjusted by applying the oil to the cut portion S by the coating apparatus 70 only once for every predetermined number (for example, 10) of labels.

  Further, when a plurality of labels L are issued and pasted continuously, the control unit 101 sets the oil so that the application unit 72 (in the example shown in FIG. 4, the application unit 172) is intermittently filled with oil. By controlling the oil supply by the pump 82, the total amount of oil applied to the plurality of cut portions S can be adjusted. In this case, for example, oil is supplied to the application unit 72 (in the example shown in FIG. 4, the application unit 172) only once every predetermined number (for example, 10) of labels is issued or every predetermined time. With this, the amount of oil can be adjusted. In this case, the operation of pressing the application unit 72 (the application unit 172 in the example shown in FIG. 4) against the cut portion S of the label continuum LC may be performed every time the label is issued, or the application unit 72 (FIG. In the example shown in FIG. 4, it may be performed only when oil is supplied to the application unit 172).

  By adjusting the total amount of oil applied to the label continuum LC by the control unit 101, an appropriate amount of oil can be attached to the cutters 95a and 95b. Therefore, adhesion of glue to the cutters 95a and 95b, adhesion of oil from the cutters 95a and 95b to the label continuum LC, and waste of oil can be suppressed.

[Label issuing operation]
An example of the operation of issuing the label L by the label issuing machine 8 will be described with reference to the schematic diagrams shown in FIGS. 7 and 8, only the main components of the label issuing machine 8 and the label sticking machine 10 are shown in a simplified manner.

  FIG. 7A shows a standby state before the label L issuing operation is started. In the standby state, the leading end of the label continuum LC is disposed at a predetermined position between the printing unit 91 and the cutting means 95 in the label supply direction (the direction of arrow F shown in FIG. 2).

  As shown in FIG. 7B, when the label L issuance operation is started, the printing roller 92 and the assist roller 93 are rotated in the reverse direction, and the leading end of the label continuous body LC is printed with the printing unit 91. It is drawn into the nip part between the rollers 92.

  When the leading end of the label continuum LC reaches the nip portion, printing on the printing surface is performed within a predetermined length from the leading end of the label continuum LC. When printing on the printing surface of the label continuum LC by the printing unit 91 is started, the rotation directions of the printing roller 92 and the assist roller 93 are reversed in the forward direction. Thereby, as shown in FIG.7 (c), the feed of the label continuous body LC to a label supply direction (arrow F direction shown in FIG. 2) is started.

  The print range and print contents on the label continuum LC are determined based on information including the product master and the label master stored in the storage unit 102. When the feed of the label continuum LC proceeds, the leading end of the label continuum LC is sent out to the outside of the housing 120 of the issuing machine 8 through the label issuing port W (see FIG. 2).

  As shown in FIG. 8A, when the label continuum LC is fed until the part to be cut S reaches the contact part with the coating part 72, the feeding of the label continuum LC is temporarily stopped, and the coating device The oil is applied to the cut portion S by 70. The part to be cut S of the label continuum LC is determined based on the label length information included in the label master. In addition, when using the coating device 70 of the structure shown in FIG. 4, the oil application operation | movement by the coating device 70 is performed, continuing the feed of the label continuous body LC.

  As shown in FIG. 8B, when oil is applied to the cut portion S, the application portion 72 is separated from the label continuum LC and the feed of the label continuum LC is resumed.

  As shown in FIG. 8C, when the feed of the label continuum LC is completed, the movable cutter 95a is driven to slide, and the label continuum LC is cut at the cut portion S by the movable cutter 95a and the fixed cutter 95b. The The portion cut from the label continuum LC by this cutting is issued as a label L. At this time, it is preferable that the label continuum LC portion sent out from the bell issuing port W is sucked and held on the lower surface of the suction block 50 of the label applicator 10, so that the label continuum LC can be cut well. Is called.

  When the label continuum LC is cut by the cutting means 95, the printing roller 92 and the assist roller 93 are driven to rotate in the opposite directions until the label continuum LC returns to the standby state shown in FIG. Back fed.

  The label L issued by the label issuing machine 8 is attached to the upper surface of the product G by the label applying machine 10. Specifically, for example, the sticking arm 31 descends from the upper side of the label L sucked and held on the lower surface of the sucking block 50, and the label L pushed downward by the sticking arm 31 is stuck on the upper surface of the product G. .

  When issuing only one label L, the label issuing operation is completed by the above-described operation shown in FIGS. 7 and 8, and when issuing and pasting a plurality of labels L continuously, FIGS. The above operation shown in (5) is repeated a plurality of times, and each time the label L is issued, the sticking operation by the label sticking machine 10 is performed.

  According to the label issuing operation described above, oil is applied to the cut portion S of the label continuum LC before cutting (see FIG. 8A). The adhesive strength of the part along the line is effectively reduced. Therefore, it is possible to suppress the glue on the glue surface of the label continuous body LC from adhering to the blades of the movable cutter 95a and the fixed cutter 95b, thereby reducing the cleaning frequency of the blades of these cutters 95a and 95b, or Cleaning is unnecessary.

  Further, since the oil is directly applied to the cut portion S of the label continuum LC, it is easier to adjust the amount of oil attached to the cut portion S than in the prior art in which oil is applied to the cutting means. For example, as described above, the amount of oil attached to the cut portion S can be easily adjusted by adjusting the width R (see FIG. 5) of the portion 200 to be coated in the label continuum LC. Therefore, it is possible to prevent excessive oil from adhering to the cut portion S and its peripheral portion.

  Furthermore, if the conventional technique of applying oil to the cutting means is adopted, if the width of the label continuum LC (dimension in the short direction) is smaller than the width of the blades of the cutters 95a and 95b, the label continuum LC is contacted. If oil is applied also to the blade portion that does not, the oil is wasted, and the oil applied excessively to the cutters 95a and 95b may adhere to the label L and the quality of the label L may be deteriorated. Specifically, there is a concern that the print surface of the label L may be discolored, lit or stained, or the label L may be difficult to stick to the product G. On the other hand, according to this embodiment, since an appropriate amount of oil can be applied to the label continuum LC, waste of oil can be suppressed and deterioration of the quality of the label L due to excessive oil adhesion can be prevented. it can.

  Further, according to the present embodiment, when a plurality of labels L are issued and pasted continuously, oil is applied along the cut portion S of the label continuum LC (FIG. 8A). 8), the adhesive strength at the tip of the cut continuous label body LC shown in FIG. 8C is reduced by oil. Therefore, when the label continuum LC is back-fed for printing on the next label L (see FIG. 7B), there is also an effect that the leading end of the label continuum LC does not easily wind around the print roller 92.

  Further, according to the present embodiment, when a plurality of labels L are issued and pasted continuously, the oil application operation by the application device 70 and / or the oil supply by the oil pump 82 are intermittently performed as described above. The total amount of oil applied to the label continuum LC can be adjusted. For this reason, it is possible to effectively suppress the deterioration of the quality of the label L due to the excessive adhesion of oil and the waste of oil while suppressing the adhesion of glue to the cutters 95a and 95b.

  While the present invention has been described with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments.

  For example, in the above-described embodiment, the label issuing machine for upper application that issues a label to be attached to an object to be attached from the upper side has been described. However, for lower application to issue a label to be attached to an object to be attached from the lower side. It can also be applied to other label issuing machines. Further, the present invention is not limited to the label issuing machine mounted on the label applying apparatus, but is equally applicable to a label issuing machine mounted on an apparatus other than the label applying apparatus, or a label issuing machine used alone.
