Description

  The present invention relates to a label issuance and sticking apparatus for superimposing a transparent label and an opaque label issued from a printer and sticking them to a product, and a label sticking apparatus used for the label issuing and sticking apparatus.

  Labels on which product names, prices, dates, barcodes, and the like are printed are affixed to packaged products such as fresh food sold at supermarkets and convenience stores. If the size of the label in that case is relatively larger than the product size, there is a problem that the contents of the packed product are hidden by the label and cannot be seen.

  In addition, in prepared foods and lunch boxes, raw materials and additives are printed on the label in addition to the above-mentioned printing information. If a label with an increased printing amount is affixed to the lunch box, the contents are hidden from the customer. It gives distrust. Therefore, recently, a band winding device disclosed in Patent Document 1 below is becoming widespread. This device prints necessary product information on a strip-shaped transparent tape and wraps the product information on packed products such as side dishes and lunch boxes. If this is used, since product information is printed on a transparent tape, there is an advantage that the contents are not hidden more than necessary even if the amount of printing increases.

  On the other hand, there is a transparent label disclosed in the following Patent Document 2 as an alternative to the conventional paper label. This label is formed by forming a label with a transparent resin tape and affixing the label to a mount at a constant pitch so that it can be issued one by one with an existing label printer.

JP 2009-83911 A JP 11-133864 A

However, in the band winding device disclosed in Patent Document 1, there is a problem that applicable products are limited to substantially rectangular parallelepiped because of the relationship of winding a band-shaped transparent tape around the products.
On the other hand, since the transparent label of patent document 2 replaces a paper label, there is a merit that a product is not limited. However, when a barcode is printed on a transparent label, there is a problem that it cannot be read by a barcode reader.

  This problem can be solved by overlaying an opaque label on the back surface of the transparent tape as disclosed in Patent Document 1. However, since the overlay mechanism adopted in Patent Document 1 superimposes while transporting the transparent tape and transports the opaque label at the same speed from above, the mechanism is applied to an existing label printer. There is a problem that cannot be done.

  The present invention was developed in view of these problems, and a new label issuance that can be applied to a product after finishing the barcode printed on the transparent label with an existing label printer into a label that can be read by a barcode reader. It is an object of the present invention to provide a sticking device and a label sticking device used therefor.

  The label issuing and pasting device according to the present invention has a first label issuing unit for issuing a transparent label having an adhesive surface on the back side and product information printed on the surface, a second label issuing unit for issuing an opaque label, A label affixing device that receives the issued transparent label and the opaque label and affixes the product to the product, the label affixing device overlaying the opaque label on a part of the received transparent label and affixing the product to the product It is characterized by that.

  Here, when an opaque label is superimposed on a part of a transparent label, when a machine-readable code such as a bar code or a QR code (registered trademark, the same applies hereinafter) is printed on the transparent label, the code is printed. It is to overlay an opaque label on the back of the column. Alternatively, the code is printed on an opaque label without printing the code on a transparent label, and these are superimposed. In this case, the overlay position may be, for example, a bar code printing scheduled field of a transparent label or a blank field of a transparent label. When superimposing the marginal margin, a part of the opaque label may partially protrude from the transparent label. If the column of the machine-readable code such as a barcode is deleted from the transparent label, the transparent label can be reduced in size.

  1 to 3 are plan layout views for explaining the solution principle of the present invention. In these drawings, the label issuing and pasting device 100 includes a first label issuing unit P1, a second label issuing unit P2, and a label pasting device 110. The first label issuing unit P1 issues a transparent label L1, and the second label issuing unit P2 issues an opaque label L2. In FIG. 1 to FIG. 3, the label issuing units P <b> 1 and P <b> 2 are arranged side by side, but the present invention is not limited to this, and may be arranged, for example, facing each other. Further, in front of these label issuing portions P1 and P2, a label sticking device 110 for receiving the issued transparent label L1 and the opaque label L2 in order and sticking them on the upper surface of a product (not shown) is arranged. Further, they are electrically connected to each other so that the label issuance and the label applying operation are interlocked.

  In FIG. 1, the transparent label L1 issued from the first label issuing unit P1 is sent out onto the first support base R1, and the opaque label L2 issued from the second label issuing part P2 is sent to the second support base. The state sent out on R2 is shown. In addition, the opaque label L2 on the second support base R2 is fed forward and is separated from the subsequent opaque label. However, when the subsequent opaque label is in the course of upward inclination, and the issued opaque label L2 is held in a substantially horizontal posture at the leading edge of the upward inclination, the pasting head H to be described later has these opaque labels. Since the succeeding label is not adsorbed by the sticking head H even if it is placed on the cover, in this case, the issued opaque label L2 is not sent forward and is continuously spaced from the succeeding opaque label at a predetermined interval. To do.

  The label sticking device 110 includes a sticking head H that adsorbs the transparent label L1 or the opaque label L2, a moving mechanism D described later that moves the sticking head H in the X-axis direction F1, the Y-axis direction F2, and the Z-axis direction F3. A control unit, which will be described later, drives and controls the moving mechanism D to sequentially receive and superimpose the transparent label L1 on the first support base R1 and the opaque label L2 on the second support unit R2, and then affix them on the upper surface of the product. C.

  The transparent label L1 is obtained by applying a pressure-sensitive adhesive to the back surface of a transparent resin tape, and the product name, price, date, barcode, and the like are printed on the surface. The print format at that time is, for example, a product name field a at the top, a date field b such as an expiration date or a processing date, a bar code field c and a price field d at the bottom, and a store name at the bottom. A print field e is arranged. However, this format is an example, and the arrangement position is changed according to the print contents and the pasting position.

  The opaque label L2 is a plain label having a size that overlaps with a printing field c of a machine-readable code such as a barcode or a QR code. However, a barcode, QR code, or the like may be printed on the opaque label L2. In addition, as shown in FIG. 1, when the bar code field c and the price field d are arranged side by side and the opaque label L2 has a width across them, the bar code field c and the price field d are superimposed on the back surface of both printing fields. The back surfaces of the code field c and the price field d may be covered with the opaque label L2.

  The first label issuing unit P1 issues print information of the designated product while printing it on the transparent label L1 in a predetermined format. The transparent label L1 set at that time may be a label with a mount that is affixed to the mount at a fixed pitch, or may be a mountless label that does not use a mount. When the latter mountless label is used, a cutter that cuts off the printed transparent label L1 from the subsequent transparent tape is provided on the upstream side of the first support base R1. In addition, when performing weighing pricing, the first label issuing unit P1 is electrically connected to an electronic scale or weighing device, and the weight of the weighed product and the calculated price are printed on the transparent label L1. When the transparent label L1 is formed of a transparent resin, the printing mechanism to be used is preferably a thermal transfer type, but may be an ink jet type.

  The second label issuing unit P2 issues an opaque label L2. When nothing is printed at the time of issuance, only a mechanism for feeding the opaque label L2 at a constant pitch is provided. Further, when printing a barcode, QR code or the like on the opaque label L2, a printing mechanism is provided. The printing mechanism in this case may be of a thermal type in addition to the thermal transfer type or the ink jet type as long as it is an opaque label using paper as a base material. The opaque label L2 set in the printer may be a label with a mount or a label without a mount. When the latter mountless label is used, a cutter is provided on the upstream side of the second support base R2 as described above. In this case, there is an advantage that the feed length of the opaque label L2 can be changed according to the length of the bar of the barcode. The second label issuing unit P2 is electrically connected to the first label issuing unit P1. When only the label issuing is instructed from the first label issuing unit P1, the second label issuing unit P2 prints the opaque label L2 without printing anything. Issue. Further, when a bar code or QR code is transmitted from the first label issuing unit P1, it is printed and issued.

  In use, first, the transparent label L1 is set in the first label issuing unit P1, and the opaque label L2 having a size overlapping the barcode printing field c of the transparent label L1 is set in the second label issuing unit P2. When a product is designated for the first label issuing unit P1, the first label issuing unit P1 prints the print information of the designated product on the transparent label L1, and also reads a machine-readable code (for example, a bar code). The printing position information in the printing column c of the (code) is transmitted to the label sticking device 110. At the same time, the second label issuing unit P2 is instructed to issue a label. Thereby, the label sticking device 110 stands by at the initial position in front of the first label issuing unit P1, and from there, the movement amount to the transparent label L1 sent to the predetermined position of the first support base R1, and from there The amount of movement to the opaque label L2 sent to a predetermined position of the two support bases R2 is obtained and set in advance.

  Subsequently, as shown in FIG. 1, when the transparent label L1 on which the product information is printed is sent to a predetermined position of the first support base R1, and the plain opaque label L2 is sent to a predetermined position of the second support base R2. 2, the sticking head H of the label sticking device 110 moves above the transparent label L1 and sucks the transparent label L1, and then moves above the opaque label L2 as shown in FIG. Then, the barcode printing field c of the adsorbed transparent label L1 is overlaid on the opaque label L2. At this time, the sticking head H is controlled to move based on the print position received from the first label issuing unit P1. Subsequently, the pasting head H moves to the upper side of the product and attaches the label on which the transparent label L1 and the opaque label L2 are overlapped to a predetermined position of the product.

  Thereby, the barcode printed on the transparent label L1 can be read by the barcode reader by the opaque label L2 superimposed on the back surface thereof.

  In the above operation, the transparent label L1 is first sucked by the sticking head H and then superimposed on the opaque label L2. When a barcode or the like is printed on the opaque label L2, the opaque label L1 is first printed. After adsorbing L2, it is superimposed on the transparent label L1. Further, when the transparent label and the opaque label are overlaid on the product, the bar code printing column may be protruded from the top surface of the product and bent on the side surface of the product.

  The label applicator used in the above apparatus is a label applicator that superimposes a transparent label on which product information is printed and a plain opaque label or an opaque label on which a machine-readable code is printed, The opaque label is attached to a product after being overlapped with a part of the transparent label.

  The position where the opaque label is overlapped with a part of the transparent label is the position of the machine-readable code printed on the transparent label. If the machine-readable code is printed on the opaque label, the opaque label is transparent. This is the position to be attached to the label margin. This position information may be sent in advance from a label printer that prints and issues a transparent label, or may be set in advance in the apparatus when the position of application to a margin is determined. When the machine-readable code is printed on the opaque label, a part of the opaque label may protrude from the transparent label. The reason why the transparent label and the opaque label are overlaid on top of each other in this way is attached to the product because the operation of attaching these labels to the product can be completed in one operation.

  According to the present invention, the opaque label is pasted on the back side of the printing field of the machine-readable code (bar code or the like) of the transparent label and then attached to the product, so that the barcode or the like printed on the transparent label is the barcode reader. Becomes readable. Therefore, even if the printing amount increases and the label size becomes relatively larger than the product size, a transparent label that does not hide the contents of the packed product more than necessary can be provided to the market.

The principal part external appearance perspective view which looked at the label sticking apparatus of FIG. 4 from the left side. The block diagram of the configuration of the control system of the embodiment.

  Hereinafter, based on FIGS. 4-7, the label issuing sticking apparatus and label sticking apparatus which concern on one Embodiment of this invention are demonstrated. In addition, this embodiment is an example and does not limit the technical scope of the present invention.

  4 to 6, the label issuing and pasting device 100 includes a first label issuing unit P1 on the left side (hereinafter referred to as a first label printer P1) and a second label on the right side arranged side by side. An issuing unit P2 (hereinafter referred to as a second label printer P2) and a label sticking device 110 disposed in front of them are provided.

<First label printer>
The first label printer P1 shown in FIGS. 5 and 6 is a known thermal transfer type printer that issues while printing product information on a label with a mount or a label without a mount. Therefore, when using a label with a mount, a release plate is provided at the label issuing port. When using a mountless label, a cutter that separates the printed label from the subsequent label and a label that receives the printed label are provided. One support base R1 is provided.

  The first support base R1 temporarily holds the issued transparent label L1, but a label feeding mechanism for feeding the transparent label L1 to a predetermined position is provided as necessary. As shown in FIGS. 5 and 6, the feeding mechanism is configured by a plurality of rollers R, and the issued transparent label L <b> 1 is supported by these rollers R. On the outer periphery of these rollers R, a ring made of silicone rubber for preventing adhesion of the adhesive of the transparent label L1 is mounted.

<Second label printer>
The second label printer P2 sequentially sends out the opaque label L2 without printing. As shown in FIG. 4, the second label printer P2 is not equipped with a printing mechanism such as a thermal head. The opaque label L2 is affixed to the mount TP at a constant pitch and wound in a roll shape, and the mount TP drawn from the roll 1 is guided to the peeling plate U via the guide roller unit 2, Therefore, by folding the mount TP at an acute angle, the opaque label L2 affixed to the mount TP is peeled off from the mount TP and sent one by one onto the second support base R2. Therefore, the mount TP is forcibly sent in the arrow direction F4 by the driving roller unit 3 and is taken up by the take-up roller unit 4.

  Further, a retaining plate 11 that swings around a lower support shaft 10 is provided on the side of the roll 1. The retainer plate 11 is slid in the arrow direction F5 to set the roll 1 in the storage portion from the side.

  The opaque label L2 is formed in a size corresponding to the barcode printing field of the transparent label L1, and the barcode is read by a barcode reader if it is superimposed on the back surface of the barcode printing field of the transparent label L1. It becomes possible.

  The guide roller unit 2 that guides the mount TP to the peeling plate U is composed of two large and small rollers 21 and 22. The peeling plate U is disposed at a position higher than the rollers 21 and 22, and the roller A path from 21 to the peeling plate U is formed in an upward slope. Further, the peeling plate U is formed at the front end portion of the L-shaped plate 23 in a side view, and the mount TP is folded back at the front end portion and is sent in the arrow direction F4 by the driving roller portion 4. A roller Rr is attached at a position slightly above the opaque label L2 running on the plate 23. This roller Rr prevents the transparent label L1 adsorbed by the sticking head H from adhering to the subsequent opaque label L2, and a silicone rubber ring for preventing adhesion is attached to the outer periphery of the roller Rr. ing. In FIG. 4, one roller Rr is shown, but a plurality of rollers Rr are arranged side by side on a common shaft.

  The drive roller unit 3 includes a drive roller 31 that forcibly sends the mount TP and a pinch roller 32 that presses the mount TP against the drive roller 31. The mount TP is formed in an S shape between the rollers 31 and 32. It is being handed over. A timing pulley 33 is attached to the rotation shaft of the drive roller 31, and a timing belt 34 is stretched between the timing pulley 33 and the drive shaft of the rear stepping motor 30 to rotate the stepping motor 30. Thus, the mount TP is intermittently sent at a feed pitch of one opaque label L2.

  The mount TP delivered from the pinch roller 32 is wound up by the winding roller unit 4 through a plurality of shafts 41 and 42. The take-up roller unit 4 includes a take-up roller 40, a slip clutch (not shown) connected to the rotating shaft, a pulley 43 connected to the slip clutch, a rear DC motor 44, and the DC motor 44. The timing belt 45 is configured to transmit the rotation to the pulley 43. Thereby, even if the winding diameter of the winding roller 40 is large and the rotational speed is reduced, the mount TP is wound up with a constant tension.

  In FIG. 5, the second support base R2 is composed of a plurality of free rollers FR arranged at a predetermined distance in a direction orthogonal to the feeding direction of the opaque label L2, and supports the opaque label L2 fed by these. It has become. In FIG. 5, only two free rollers FR are shown and the others are omitted, but a plurality of free rollers FR are arranged on the same axis. The upper end of each free roller FR is positioned at substantially the same level as the tip of the plate 23 of the peeling plate U. Thereby, the opaque label L2 peeled from the mount TP is switched to a substantially horizontal posture on the second support base R2. At this time, the mount TP is fed and stopped so that the rear end portion of the peeled opaque label L2 is slightly stuck on the mount TP of the release plate U, that is, the folded mount TP. To be controlled.

  The second support base R2 is provided with a sensor for detecting the presence or absence of the opaque label L2 held there. This sensor is composed of a photoelectric sensor, one of which is a lamp 46 and the other is a light receiver 47, and the detection light emitted from the projector 46 enters the light receiver 47 obliquely across a pair of free rollers FR. Are arranged to be.

<Labeling device>
In FIG. 5, the label sticking device 110 has a sticking head H that sucks the transparent label L1, and the sticking head H on the second support base R2 of the second label printer P2 from the first support base R1 of the first label printer P1. And a moving mechanism D for moving the product from the second support base R2 to a product attachment position (not shown).

  The sticking head H is provided with a suction part S having a damper function, a chamber CB for applying a negative pressure to the suction part S, and a blower BW for reducing the pressure in the chamber. is there. Specifically, a plurality of through holes are formed on the back surface of the suction portion S, and these through holes are communicated with each other in the chamber CB so that a negative pressure acts on each through hole. If the suction part S is moved onto the transparent label L1 on the first support base R1 and lowered, the transparent label L1 is sucked and held by the suction part S.

  The moving mechanism D includes an X-direction drive unit 6 that moves the sticking head H in the X-axis direction F6 in FIG. 6, a Y-direction drive unit 7 that moves in the Y-axis direction F7, and a Z-direction drive that moves in the Z-axis direction F8. Part 8.

  The X-direction drive unit 6 includes a pair of parallel upper and lower linear guides 61, linear blocks 62 that slide on the linear guides 61, a pair of timing pulleys 63 disposed at both ends in the X-axis direction, A timing belt 64 spanned between the timing pulleys 63 and a stepping motor 65 connected to one timing pulley 63 and causing the timing belt 64 to travel in the X-axis direction are provided. The linear block 62 is connected to the timing belt 64 and moves in the X-axis direction F6. The linear block 62 includes a Y-direction drive unit 7 and a Z-direction drive unit 8 described later. They are connected via a frame (not shown). Thus, when the linear block 62 moves in the X-axis direction F6, both the Y-direction drive unit 7 and the Z-direction drive unit 8 move in the X-axis direction F6, that is, between the first label printer P1 and the second label printer P2. It is designed to reciprocate.

  The Y-direction drive unit 7 has the same configuration, and a pair of upper and lower linear guides 71, a linear block 72 that slides on these linear guides 71, and a pair of timing pulleys 73 disposed at both ends in the Y-axis direction. And a timing belt 74 spanned between the timing pulleys 73 and a stepping motor 75 connected to one timing pulley 73 and causing the timing belt 74 to travel in the Y-axis direction F7.

  Moreover, the linear guide 71 of the Y direction drive part 7 is connected with the linear block 62 of the X direction drive part 6 through a frame omitted in the drawing. Therefore, when the linear block 62 moves in the X-axis direction F6, the Y-direction drive unit 7 moves in the same direction accordingly. Further, the Z-direction drive unit 8 is connected to the linear block 72 that slides on the linear guide 71 via a frame extending in the vertical direction, which is omitted in the drawing. For this reason, when the timing belt 74 travels in the Y-axis direction F7, the later-described Z-direction drive unit 8 along with the linear block 72 also moves in the Y-axis direction F7, that is, in the front-rear direction.

  The Z-direction drive unit 8 includes a pair of upper and lower base plates 80, a vertical linear guide 81 fixed to one corner of the base plate 80, a linear block 82 that slides up and down on the linear guide 81, and a Z-axis direction. A pair of timing pulleys 83 disposed at both ends of a frame (not shown) of F8, a timing belt 84 spanned between both timing pulleys 83, and one timing pulley 83 are connected to each other to connect the timing belt 84 to the Z-axis. And a stepping motor 85 that travels in the direction F8. A linear block 82 is connected to the timing belt 84, and a spline shaft 86 extending downward from the linear block 82 is rotatable in a horizontal plane and integrated with the linear block 82 in the vertical direction. It is attached in a state. A pasting head H is attached to the tip of the spline shaft 86. Therefore, when the timing belt 84 travels in the Z-axis direction, the linear block 82 and the spline shaft 86 connected to the linear block 82 move in the Z-axis direction F8, and accordingly, the sticking head H attached to the tip portion of the spline shaft 86. Moves in the Z-axis direction F8, that is, in the vertical direction.

  A ball spline 87 for guiding a spline shaft 86 that moves up and down is attached to the upper and lower base plates 80 connected to the linear block 72 of the Y-direction drive unit 7 via a frame (not shown) via a bearing 88. . A pulley 89 is fixed to the outer cylinder of the ball spline 87, and a timing belt 90 (see FIG. 5) is attached to the pulley 89.

  On the other hand, a stepping motor 91 is fixed to the base plate 80, and the timing belt 90 is stretched between the pulley 92 (see FIGS. 4 and 5) attached to the rotating shaft and the pulley 89. Yes. Accordingly, when the pulley 89 is rotated in the horizontal plane by driving the stepping motor 91, the ball spline 87 integrated with the pulley 89 is rotated, and accordingly, the spline shaft 86 engaged therewith is rotated around its axis. It has become.

  Moreover, when the spline shaft 86 rotates, the sticking head H attached to the lower end portion thereof rotates in a horizontal plane. The rotation range in this case is a range of ± 90 degrees. Thereby, the transparent label L1 adsorbed by the sticking head H is switched to the vertical direction or the horizontal direction.

  FIG. 7 is a configuration block diagram of the control system of the above embodiment. In this figure, a label issuing and pasting apparatus 100 includes a first label printer P1, a second label printer P2, and a label pasting apparatus 110. The label sticking device 110 includes a moving mechanism D and a control unit C. The control unit C is configured by a computer, and performs drive control described later by reading and executing a built-in program. In addition, the control unit C receives product size information and a packaging completion signal from a packaging machine 120 that wraps the product with a stretch film. Further, when a label is affixed while the packaged product packaged by the packaging machine 120 is conveyed by a belt conveyor or the like, a product detection signal is input from the product detection sensor 130.

  The control unit C receives from the first label printer P1 a print position information of the transparent label L1 and a print completion signal of the transparent label L1, and from the second label printer P2 an issue completion signal of the opaque label L2 from the packaging machine 120. The size information of the vertical / horizontal / height of the product and the pasting position information for pasting the transparent label L1 on the upper surface of the product are input.

  Under such a configuration, when the transparent label L1 is set in the first label printer P1, the opaque label L2 is set in the second label printer P2, and the packaging machine 120 and the label applicator 100 are operated, the control unit C First, the moving mechanism D is controlled to make the sticking head H stand by at an initial position.

  Subsequently, when a product is specified for the packaging machine 120, the packaging conditions corresponding to the product, for example, the size and height of the tray to be used, the packaging speed, etc. are set in the packaging machine 120, and the designated product Is transmitted to the first label printer P1. Then, the first label printer P1 reads out and sets the print information of the designated product, and transmits the print position information in the bar code print field to the control unit C of the label sticking device 110. At the same time, after instructing the second label printer P2 to issue a label, printing of the transparent label L1 is started.

  On the other hand, the control unit C that has received the print position information moves from the initial position in front of the first label printer P1 to the transparent label L1 sent to a predetermined position of the first support base R1, and from there to the second support. The amount of movement to the opaque label L2 sent to a predetermined position on the table R2 is obtained and set.

  Then, the first label printer P1 prints and issues the transparent label L1, the second label printer P2 issues the opaque label L2, the transparent label L1 stops at a predetermined position on the first support base R1, and the opaque label L2 When stopped at a predetermined position on the second support base R2, the control unit C controls the X-direction drive unit 6 and the Y-direction drive unit 7 at the same time, and moves the pasting head H on standby onto the first support base R1. Subsequently, the Z-direction drive unit 8 is driven and controlled, and the sticking head H is lowered onto the transparent label L1, and then reversed immediately.

  Thereby, the transparent label L1 is adsorbed by the sticking head H. Subsequently, the control unit C drives and controls the Y-direction drive unit 7 and the X-direction drive unit 6 at the same time to move the sticking head H onto the opaque label L2 of the second support base R2. Subsequently, the Z-direction drive unit 8 is moved. The drive control is performed so that the bar code printing field of the transparent label L1 adsorbed by the sticking head H is superimposed on the opaque label L2.

  Then, the control part C drives and controls the Y direction drive part 7, and moves the sticking head H to the upper direction of the label sticking position of goods. At that time, since the opaque label L2 on the second support base R2 is transferred forward in a state of being attached to the back surface (adhesive surface) of the transparent label L1, the rear edge of the opaque label L2 is partially attached to the mount TP. Even if attached, the opaque label L2 is completely separated from the mount TP. Subsequently, when the second label printer P2 detects that the opaque label L2 disappears on the second support base R2 by a signal from the light receiver 47, it prepares for the next opaque label L2.

  On the other hand, the sticking head H that has moved to the label sticking position of the product is lowered by the drive control of the Z-direction drive unit 8 by the control unit C at the timing when the product reaches the sticking position. Thereby, the transparent label L1 adsorbed by the sticking head H and the opaque label L2 partially overlapped on the back surface thereof are stuck at designated positions on the upper surface of the product. The descending distance of the sticking head H at that time is controlled based on the product height information transmitted from the packaging machine 120. Further, the suction part S is provided with a reflection-type article detection sensor (not shown). When the sensor detects a product, the control part C drives and controls the Z-direction drive part 8 to raise the sticking head H. Let

  Further, when changing the sticking posture of the transparent label L1 from the vertical orientation to the horizontal orientation, the stepping motor 91 is driven and controlled when the transparent label L1 is lifted while being attracted by the sticking head H and moved in the Y-axis direction. The spline shaft 86 is rotated 90 degrees. Subsequently, the control unit C drives and controls the X direction driving unit 6 to move the transparent label L1 adsorbed by the sticking head H onto the second support base R2. The subsequent operation is the same as described above.

  In addition, when the transparent label L1 extended long in the label issuing direction is changed from the vertical direction to the horizontal direction, the transparent label L1 may protrude greatly from the second support base R2. However, even in this case, the second support base R2 is the peripheral portion. Therefore, the transparent label L1 does not adhere to the peripheral portion.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, Other embodiment is also employable. For example, the transparent label L1 that is relatively small with respect to the sticking head H does not flutter at the suction portion S even if it is moved simultaneously in the X-axis direction and the Y-axis direction. Alternatively, the first support base R1 and the second support base R2 may be moved while drawing a path for a shortcut.

  Moreover, in the said embodiment, although the 1st label printer P1 and the 2nd label printer P2 were installed side by side, this may be installed facing each other and the movement distance to a X direction may be eliminated.

  In the above embodiment, the transparent label L1 is first lifted and overlapped on the opaque label L2. However, when printing a barcode on the opaque label L2, the second label printer P2 has a printing mechanism. Attach the barcode information from the first label printer P1 to the second label printer P2. When the opaque label L2 is issued, the opaque label L2 is first lifted by the sticking head H, and is superimposed on the transparent label L1. In that case, it may be overlaid on the barcode printing scheduled column of the transparent label, or when the barcode printing column is deleted, the opaque label L2 may be partially overlapped and pasted on the margin of the transparent label L1. good.
