The label affixing unit 41 includes three driving mechanisms. The first driving mechanism includes a horizontal motor and a driving circuit that drives the horizontal motor, and the label adsorption unit surface is horizontal, that is, orthogonal to the conveyance direction of the product. This is a circuit for driving a horizontal motor (first driving machine) that moves in the direction of movement, and a stepping motor is used as the horizontal motor. Therefore, the position of the label suction unit can be detected by counting the number of drive pulses of the stepping motor. For example, the stepping motor is configured to have a positive count when rotating clockwise and a negative count when rotating counterclockwise. The label attaching unit 41 includes a horizontal reference position sensor. The horizontal reference position sensor is a sensor that detects that the label suction unit is positioned at a reference position in the horizontal direction, and the drive pulse from the reference position is detected. The label adsorbing portion is positioned in the horizontal direction according to the count value.

  The second drive mechanism includes a vertical motor, a drive circuit for driving the vertical motor, and a vertical reference position sensor, and the vertical motor (second drive mechanism) moves the label adsorption portion in the vertical direction.

The product is moved away from the product in the horizontal width direction (the right side length LL of the product + the left side length LR of the product). The width (dimension L) of the article W is used for controlling the packaging machine. The width detection sensor 15a transmits the length data L, that is, (LL + LR) to the control unit of the label issuing unit 40 (measurement label printer).

  The detection sensor 15b for detecting the height H of the article W has a projector and a light receiver, and a large number of light projectors and light receivers are placed at predetermined intervals in the height direction with the transport path in the middle of the product transport path. The height H of the product is detected by blocking the light of the projector according to the height of the product arranged individually and conveyed on the conveyance path. The height data is used for controlling the packaging machine and is transmitted to the control unit of the label issuing unit 40 (measurement label printer).

Further, the detection sensor 15a for detecting the vertical width w of the article W is configured such that the position P0 of the sensor with respect to a predetermined reference point and the article W placed on the article placement unit 12 are pushed by the pusher of the pusher conveyor 13.

The control unit 31 adjusts the timing of labeling on the article W based on the signal.

  The second article detection sensor 36 indicates whether or not the article W is placed on the transport conveyor (transport means 1) disposed in the front part of the discharge path (heat seal section 10) or in the vicinity thereof. Is output. The second article detection sensor 36 includes a light emitting unit, a light receiving unit, and the like.

  In the above-described embodiment, the conveyance process, the pasting process, and the like are performed based on signals from sensors such as the commodity detection sensor 59, the first article detection sensor 35, and the second article detection sensor 36. It is not limited. For example, the transporting process, the pasting process, and the like may be performed based on the tray dimensions detected by the sensors 15a and 15b or the like or the set tray dimensions.

  The control unit 31 comprehensively controls each component. The control unit 31 executes the control program (PRG) read from the storage unit 32, thereby causing the label sticking device 100 as a computer to realize each function.

The control unit 31 includes a determination unit 31a, a sticking control unit 31b, and the like.
The determination unit 31a performs a process of determining whether or not the label attached to the article w protrudes to the pusher 8 side based on the size of the article, the size of the label, the print item, and the like.

The sticking control unit 31b performs a process of prohibiting the sticking of the label to the article by the label sticking unit 41 as sticking means when the judging part 31a determines that the label stuck to the article protrudes to the pusher 8 side.
For example, when detecting a signal indicating the completion of manual label application from the display operation unit 4 as an input unit, the application control unit 31b shifts from the manual label application mode to the automatic label application mode and automatically applies the label. Control to resume processing.

  Since the label issuing unit 40, the label pasting unit 41, the pasting drive unit 42, and the like have been described above, description thereof will be omitted.

  FIG. 5 is a diagram showing an example of the mountless label L of the label sticking apparatus 100 according to the embodiment of the present invention. Specifically, FIG. 5A shows a mountless label L1 having a short label length, FIG. c) is a diagram showing an example of a mountless label L2 having a long label length.

  The width X of each mountless label L1, L2 is defined to be a constant value. Each mountless label L1 and L2 has a length (label length) Y1 along the printing direction, which is included in the product printed on the upper surface pasting area up to the barcode and the side surface pasting area below the barcode. The length is variable depending on the amount of materials and raw materials. Accordingly, the length Y1 of each label is defined by the size of the print data printed on the label. Note that LC in each of the mountless labels L1 and L2 in FIG. 5 is a substantially central coordinate in the upper surface pasting region.

FIG. 6 is a diagram illustrating an example of the positional relationship between the label of the label sticking apparatus according to the embodiment of the present invention and the sticking target object.
As shown in FIG. 6, the label affixing device 100 affixes a label L to an article W (tray) having a horizontal length (horizontal width) X0 and a vertical length (depth) Y0. In the label pasting data file, distance data (X2, Y2) from the end of the tray to the center of the label is set. For example, the label affixing position on the tray is the distance from the adjacent side (edge) of the tray to the center of the label. For example, X2: 30 mm and Y2: 130 mm are set for a tray having a width of 200 mm and a length of 150 mm. Is done. In this case, there is a blank distance (S1) between the outer periphery of the label on the tray and the end of the tray.

Further, the movement distance (horizontal movement distance data) X of the pasting means is the distance data (X2, Y2) from the tray end to the center of the label set in advance and when the width of the tray is detected during the packaging process. Is calculated. Based on the calculated movement distance X and timing data T, label sticking control is performed. However, the moving distance X and the timing data T may be calculated before the packaging operation by associating the tray file to be used with the label pasting data file. That is, the tray is placed at the center of the product placement section 12, and the lateral width (L) of the tray and the distance X2 from the tray end to the center of the label are known, so the movement distance X is determined.
The control unit 31 can calculate the length of Y3 in Lb by calculating the coordinates of the label attaching position (LC) on the tray, and when the value of Y3 is a value (negative number) smaller than zero, It is determined that the label L protrudes from the end of the surface to be pasted on the product upper surface. When the value of Y3 is greater than zero (a positive number), it is determined that the label L is to be attached within the application surface of the product upper surface. Therefore, the length of the mountless label printed in variable length (print image length) and the size of the set values of X2, Y2, and S1 set in advance are variable in length. It is determined whether or not the side sticking region Lb protrudes from the end of the product when the label is attached.

Next, the variable-length label and the article W as a label application target will be described with reference to FIGS. 7 (a), 7 (b), and 7 (c).
As shown in FIG. 7A, when the short label L is pasted on the surface to be pasted Wa on the top surface of the article W, the end of the label L is pasted without sticking out from the surface to be pasted Wa on the top surface of the product. The

  As described above, the relatively long label L is attached to the top surface Wa of the top surface of the article W by the label pasting portion 41 and the side surface pasting area Lb that is pasted to the side surface Wb of the article W. And a bent portion LL between the upper surface sticking region La and the side surface sticking region Lb.

  As shown in FIG. 7B, when a relatively long label L is pasted on the adherend surface Wa on the upper surface of the article W, the upper face pasting area La of the label L is applied to the adherend surface Wa on the upper face of the article W. The label L is placed so that the bent portion LL of the label L is positioned at the end of the adherend surface Wa on the upper surface of the article W, and the side face adhesion region Lb of the label L is formed on the adherend surface Wa on the upper face of the article W. It will be in the state which protruded from the edge part.

Next, as illustrated in FIG. 7C, when the label L is bent into a substantially L shape at the bent portion LL, the side surface pasting region Lb of the label L is in a state of being pasted on the side surface Wb of the article W. .
When a longer label L is attached to the article W, the label is bent into a substantially U shape and attached to the bottom surface of the article W.

  FIG. 7D is a diagram showing an example of a state in which the size of the label is larger than the article w to be attached and the label protrudes to the pusher 8 side. As shown in FIG. 7D, when the label sticking device 100 according to the embodiment of the present invention determines that the label may protrude to the pusher 8 side, the label sticking unit 41 applies the label to the article w. The sticking process is prohibited and the hand sticking mode is set. As shown in FIG. 7E, the operator attaches the long label to the object to be attached (article), and as shown in FIG. 7F, the operator folds the label area where the long label protrudes. Let it stick to the side.

  As will be described later, the label sticking apparatus 100 according to another embodiment of the present invention, as shown in FIG. 7 (d), determines that the label may protrude to the pusher 8 side. 31 automatically corrects the label sticking position or manually sets the label sticking position by the operator, so that the long label is stuck on the sticking object (article) as shown in FIG. As shown in FIG. 7 (f), the extended label area of the long label is bent by an operator or the like and attached to the side surface.

<An example of operation | movement of the label sticking apparatus 100>
Next, an example of operation | movement of the label sticking apparatus 100 which concerns on embodiment of this invention is demonstrated, referring FIGS. FIG. 11 is a diagram showing an example of a label format image and a print label. FIG. 12 is a flowchart showing an example of the operation of the label sticking apparatus 100 according to the embodiment of the present invention. FIG. 13 is a flowchart showing an example of the operation of the normal label automatic sticking mode of the label sticking apparatus 100. FIG. 14 is a flowchart illustrating an example of the operation of a routine for developing dot data by the control unit 31 of the label sticking apparatus 100.

  In step S <b> 1, the control unit 31 refers to the RAM 34 and determines whether or not it is a valued mode for issuing a label. When it is determined that the mode is not the pricing mode (NO), the control unit 31 proceeds to step S2, and when it is determined that the mode is the pricing mode (YES), the control unit 31 proceeds to step S3.

  In step S2, the control unit 31 performs control such as file data setting in the setting mode, output of a result report in the report mode, and maintenance in the maintenance mode, and the process proceeds to step S1.

In step S <b> 3, the control unit 31 reads the product number of the product to be printed from the storage unit 32 or the like in accordance with the operation of the display operation unit 4 by the operator (operator). Since the product file stores the label format number and the tray format number in association with each other, for example, when the label format number # 1 is set to the specified product number of the product file, the control unit 31 selects the format number. Processing for reading the format data of the print area information of each print item including the label length data specified by # 1 is performed. In the format data specified by the format number # 1, the product name has a print range of 3 lines and the additive has a print range of 4 lines (see FIG. 11A). Also, the tray number set in the tray file is determined by the tray format number set in the product number. Is read out, the horizontal width, height, and depth of the tray to be used, the label affixing position (X0, Y0), the horizontal movement distance X in the device of the affixing unit, the timing when the affixing unit descends, the affixing unit 90 ° The information on whether to rotate or 180 ° is read out.
When the product number 0001 is designated, the product data (for example, product name, price, additive, etc.) of the product specified by the product number 0001 is called as the product data of the product to be priced. It is assumed that the product additive specified by the product number 0001 has a print data amount for one line (see FIG. 8).

  In step S4, the control unit 31 performs processing for expanding the print data of the called commodity data into dot data in accordance with the called format. Details of the dot data development processing will be described with reference to FIG. When the label length data in the bell format area called in step S3 and the print position in the paper transport direction are packed upward in step S48 of FIG. 14 described later, the control unit 31 subtracts the number of lines to be packed and subtracts the label length. calculate. That is, the reference label length is read in S3, the height of the character for one character is determined in advance, and the length between lines of the character in the discharge direction of printing is also determined in advance. The length of the number of lines packed can be calculated, and the label length to be issued can also be calculated.

  In step S <b> 5, the control unit 31 determines whether or not the label protrudes from the end of the surface to be pasted to the pusher side based on the print item, the label size, the size of the article, and the like.

  In step S6, when it is judged that the label protrudes from the edge part of the to-be-pasted surface of the articles | goods w to the pusher side in step S6, it progresses to the process of step S8, and in the case of other than that, it progresses to the process of step S7.

  In step S7, the control unit 31 performs a label sticking process in a normal label automatic sticking mode. The label sticking process in the normal label automatic sticking mode will be described with reference to FIG.

  As shown in FIG. 13, in step S21, the control unit 31 indicates that the weighing of the article W (product) placed on the weighing unit 50 of the product placing unit 12 of the stretch film packaging machine is stable. The presence or absence of input is determined. When there is no measurement stable signal input (NO), the control unit 31 repeats the determination until there is a stable signal input, and when there is a measurement stable signal input (YES), the process proceeds to step S22.

  In step S22, the control unit 31 controls the thermal head 25b and the platen roller based on the developed dot data, and performs a printing process on the mountless label tape. Then, the calculated label length data is transmitted to the packaging mechanism control unit 102E.

  In step S23, the control unit 31 controls the cutter to cut the mountless label tape and issue a sheet-like mountless label. For example, if the control unit 31 calls the format of format number # 1 in step S3 and the product data of the product of product number 0001 in step S4, the control unit 31 issues a label as shown on the right side of the arrow in FIG. Perform the process.

  In step S24, the control unit 31 is based on the print format information including the print item read in step S3, the tray format information including the tray size, the label length (label size) calculated in step S4, and the like. The moving distance (X) and the descending timing (T) of the label attaching part 41 are specified, and the time taken from printing to label attaching is calculated.

  In step S25, the control part 31 performs the process which transmits the information which shows the time calculated from the printing calculated above to label sticking to the packaging mechanism control part E.

  In step S <b> 26, the control unit 31 moves the label suction unit of the label pasting unit 41 to the label issuing port of the label issuing unit 40.

  In step S27, the control unit 31 performs processing for moving the label suction unit to the standby position after the label suction unit C1 sucks the label L held in the label issuing port and sucks the label L.

  In step S28, the label adsorbing portion C1 is rotated based on the 0 °, 90 ° or 180 ° rotation flag setting for the tray number set in the tray format of the product file. For example, the tray number 1 is set in the tray format of the product number 0001, and the tray number 1 is set with a 90 ° rotation flag in the tray file, so the label suction portion of the label pasting portion 41 is rotated 90 °. (See FIGS. 8 and 10).

  In step S <b> 29, the control unit 31 starts the descent of the label suction unit of the label pasting unit 41 from the standby position, and performs a process of pasting the label on the package as the article W. The descending timing is advanced or delayed according to the difference in length with respect to the reference label length.

  In step S <b> 30, the control unit 31 controls to paste the first region La of the label on the surface Wa of the article while the second region Lb of the label protrudes from the surface Wa of the article W. I do.

  In step S <b> 31, the control unit 31 determines whether or not the label is attached to the upper surface of the article W to be sucked and held by the label suction unit of the label sticking unit 41 using a signal from a sensor (not shown). Determination of label sticking by the control unit 31 is performed based on a detection signal from a label sticking sensor (not shown). And detection operation is repeatedly performed until label sticking is confirmed, and when the control part 31 detects label sticking, it progresses to the process of step S32.

  Step S32... The control unit 31 performs the process of moving the label sticking unit 41 to the initial position after making the label sticking unit 41 ascend and waiting for the next label sticking. Then, the process proceeds to step S1 shown in FIG.

  As shown in FIG. 12, in step S8, the control unit 31 performs a predetermined printing process. In detail, the control part 31 performs the process of step S22 and step S23 shown in FIG.

  In step S <b> 9, the control unit 31 performs a process of suppressing (prohibiting) label sticking to the article w by the label pasting unit 41.

  In step S <b> 10, the control unit 31 performs control so that the label is held by the label holding unit of the label issuing unit 40 when the label is issued by the label issuing unit 40.

  In step S11, the control unit 31 determines whether or not the label is removed from the label holding unit based on a label detection unit (such as an optical sensor) provided in the vicinity of the label holding unit, and the label is removed. If this is detected, the process proceeds to step S12. Otherwise, the process proceeds to step S10.

  In step S12, it is determined whether or not the user has manually applied the label to the article w. Specifically, the sticking control unit 31b of the control unit 31 determines, for example, based on a signal from the display operation unit 4 whether or not the manual pasting of the label has been completed. When a signal indicating completion is detected, the process proceeds to step S13 to perform processing for resuming label pasting processing (transition to automatic pasting mode). Otherwise, the signal detection processing according to step S12 is performed. .

  Next, an example of the operation of a rasterizing routine for dot data by the label pasting device 100 will be described with reference to FIG.

  In step S41, the control unit 31 does not perform the determination process (at least the determination process of step S42 among the determination processes of steps S42 to S45) in the label format data called in step S3 of FIG. The print item on the most upstream side with respect to the paper transport direction is searched. For example, in the first determination process, the most upstream print item is “product name”.

  In step S42, the control unit 31 determines whether or not the print item searched in step S41 is “product name”. If the determination result is not “product name” (NO), the process proceeds to step S43.

  In step S43, the control unit 31 determines whether or not the print item is “additive”. If the determination result is not “additive” (NO), the process proceeds to step S44.

  In step S44, the control unit 31 determines whether or not the print item is “raw material”. If the determination result is not “raw material” (NO), the process proceeds to step S45.

In step S <b> 45, the control unit 31 determines whether the print item is “message”.
It should be noted that the “item name”, “additive”, “raw material”, and “message” printing items determined in steps S42 to S45 are the printing range (height) in the paper transport direction according to the amount of printing data. Is predetermined as a print item for changing. More specifically, each of the print items makes the print range smaller (shorter) when the print data amount (for example, the number of lines) in the paper transport direction is smaller than the print range (for example, the number of lines) in the paper transport direction. This is predetermined as a print item.

  In step S46, when the print item searched in step S41 corresponds to any of the above "product name", "additive", "raw material", or "message" (step S42: YES, step S43: YES, step S44). : YES, step S45: YES), the control unit 31 determines whether or not the print data corresponding to the print item satisfies the height of the print item in the label format data (print range in the paper transport direction). To do. That is, for each print item that is YES in steps S42 to S45, the height of the label format data (print range in the paper transport direction) called in step S3 and the print in the paper transport direction in the product data called in step S4. The amount of print data is compared, and if the amount of print data is small relative to the height, it is determined that it is not satisfied, and if it is not small, it is determined that it is satisfied. For example, in the case of the print item “product name”, the print range (height) in the paper conveyance direction is for three lines, but the print data is as small as one line, so it is determined that it is not satisfied.

In step S47, when the control unit 31 determines in step S46 that the print data does not satisfy the height of the corresponding print item of the label format data (NO), the control unit 31 does not satisfy the height (a margin height portion). It is determined whether or not there is print data of another print item (the other print item of the label format data called in step S3) whose positions overlap with the paper transport direction. That is, the control unit 31 determines whether there is another print item of the print data in which the height position overlaps with the unfilled portion (the marginal height portion). That is, it is determined whether there is print data to be printed in a marginal height portion, which is print data of another print item of the called label format data. For example, in the case of the print item “product name”, the print range (height) in the paper transport direction is for 3 lines and the print data is for 1 line, so the unfilled part (the marginal height part) is for 2 lines. Therefore, whether or not there is print data to be printed in the two-line portion of the print data of the “bar code”, “price”, “unit”, “additive”, and “store name”. Determine whether.
That is, in step S47, when format data in which print items are arranged in parallel in the paper conveyance direction is called in step S3, a portion that does not satisfy one print item arranged in parallel (the margin is not enough). When there is a height portion), the control unit 31 determines whether or not the print data of the other print items arranged in parallel in the format data is to be printed on the unfilled portion. .

  In step 28, if the control unit 31 determines that there is no other print item of the print data whose height position overlaps (NO), the portion not satisfying the height range (the margin), the print in the called format data In the position order, the position data in the paper transport direction of all the subsequent items is subtracted so as to be narrowed upward, and the position is changed. For example, when the print item “product name” is determined in step S46, the position data in the paper transport direction of each print item of barcode, price, unit, additive, and store name is reduced by two lines of “product name”. That is, each print item is printed by being packed two lines upstream of the “product name” in the paper conveyance direction. The label length data is also shortened by two lines of “product name”.

  In step S49, the control unit 31 determines whether or not all items of the called label format data have been processed. If all items have not been processed (NO), the process proceeds to step S41 to call the called label. If all items of the format data have been processed (YES), the process proceeds to step S50.

  In step S50, the control unit 31 converts the item data of the same item in the called item data area into the dot development area into the dot development area and writes it to the dot development area for the print item retrieved in step S41. . At this time, the processing is performed based on the position of the format data in the called format area and the font data, and the process proceeds to the main routine of FIG. When returning to the main routine, if the format number # 1 and the product number 0001 are input, the control unit 31 develops dot data as shown in FIG. That is, the print item after the product name moves upward by two lines of “product name”, and “store name” after “additive” moves upward by three lines of “additive”. Then, the label length data of the called label format data is shortened by two lines of “product name” and three lines of “additive”.

FIGS. 5A and 5B are diagrams illustrating an example in which the label length is changed using a more specific example.
In each case, the “product name” is the same as “tempura assortment”, but the data amount of “additive” varies depending on the difference in the number of assortment, and the label of FIG. The amount of data in the label of FIG. 5B is 6 lines for the same print item “additive”. For example, for the format of format number # 1 shown in FIG. ) Has a margin of two lines for the print item “product name” and one line for the print item “additive”, and is printed with a total of three lines. Therefore, the label is shorter by 3 lines than the label length set by the format number # 1. The format number # 1 is set with a reference label length, and the height of one character and the length between one line are determined in advance as described above. When the length is shortened, the length to be shortened can be known, and the label length to be issued can be calculated based on the label length in the read format.
In addition, the label in FIG. 5B has a margin of 2 lines for the print item “product name” and an excess of 2 lines for the print item “additive”. The label has substantially the same length as the set label length of number # 1.

<Other Embodiments of the Present Invention>
FIG. 15 is a flowchart showing an example of the operation of the label sticking apparatus 100 according to another embodiment of the present invention. When the label sticking device 100 of this embodiment determines that a long label protrudes from the article to the pusher side before label sticking, the control unit 31 automatically corrects the label sticking position so that the label does not stick out to the pusher side. Then, a label is pasted by the label pasting unit 41 at the corrected label pasting position. The description of the same configuration and operation as in the above embodiment is omitted.

  In step S61, the control unit 31 performs a process of correcting the label sticking position on the article so that the label does not protrude from the pusher side. Specifically, the control unit 31 is based on the size of a label and the size of an article (product) such as a package, and more specifically, based on the size of the label and the pusher operation direction of each article. The label sticking position is corrected so that the label does not protrude from the end of the pusher to the pusher side.

  In step S <b> 62, the control unit 31 performs a process of applying a label to the article at the corrected label application position by the label application unit 41.

  In step S63, the control unit 31 moves the article w to the discharge unit by controlling the pusher 8 to push the article W to which the label is attached from the label application region Lp to the discharge unit side. For example, the process proceeds to step S1. The control part 31 complete | finishes the said series of label sticking processes, when label sticking to all the articles | goods w which are sticking objects is complete | finished.

  As described above, in the label sticking device 100 of the present embodiment, the control unit 31 automatically corrects the label sticking position so that the label stuck to the article does not protrude to the pusher side. For this reason, even when the label is relatively large with respect to the article w, the operator automatically corrects the label sticking position without performing a special operation, and sticks the label so that it does not protrude to the pusher side. Possible labeling device 100 can be provided. For example, when the label sticks out on the opposite side to the pusher side of the surface to be pasted of the article, the operator can easily attach the label by manually pasting the protruding label portion onto the article w. Can do.

<Modification of Other Embodiment of the Present Invention>
FIG. 16 is a flowchart showing an example of the operation of the label sticking apparatus 100 according to a modification of the other embodiment of the present invention. If the label sticking apparatus 100 of this embodiment determines that a long label protrudes from the article to the pusher side before sticking the label, the label setting screen is displayed on the display / operation unit 4 so that the operator can apply the label sticking position and details. In this case, the protruding width is manually set, and a label is pasted by the label pasting unit 41 at the set label pasting position. The description of the same configuration and operation as in the above embodiment is omitted.

  In step S <b> 71, the control unit 31 performs a process of causing the display operation unit 4 to display a screen for setting the label pasting position.

  In step S72, the operator operates the display operation unit 4 to input information indicating the label pasting position. Specifically, when information indicating the label application position is input from the display operation unit 4, the control unit 31 sets the label application position based on the input information (step S73).

  In step S <b> 74, the control unit 31 controls the label pasting unit 41 to perform a process of pasting a label at the label pasting position of the article set by the label pasting unit 41.

  In step S75, the control unit 31 moves the article w to the discharge unit by controlling the pusher 8 to push the article W to which the label is attached from the label application region Lp to the discharge unit side. For example, the process proceeds to step S1. The control part 31 complete | finishes the said series of label sticking processes, when label sticking to all the articles | goods w which are sticking objects is complete | finished.

  As described above, the label sticking apparatus 100 according to the present embodiment displays the label sticking position setting screen when it is determined that the label protrudes to the pusher side, for example, when the label size is larger than the size of the article. The label attaching position can be easily set so as to be the desired position, and the label attaching section 41 can attach a label to the label attaching position.

As described above, the label sticking device 100 according to the embodiment of the present invention sticks the label issued from the label issuing unit 40 to an article. The label sticking apparatus 100 sucks and holds the label issued from the label issuing part 40 by the label sticking part, and in the label sticking region Lp, a label sticking part 41 which is sticking means for sticking the label to a predetermined position of the article; Whether or not the label stuck to the article protrudes to the pusher side based on the pusher 8 that pushes the article in the label pasting area from the label pasting area Lp to the article discharge section and the size of the article and the size of the label. If the determination unit 31a determines that the label attached to the article protrudes to the pusher 8 side, the label application unit 41, which is an application means, prohibits application of the label to the item. And a sticking control unit 31b.
The operator picks up the label held in the holding part of the label sticking part 41 and performs so-called hand sticking on the package which is the article.
In this way, even when the label is larger than the packaged item (article), by prohibiting label sticking by the label sticking part, the label does not stick out on the pusher side, and the label is stuck on the pusher by mistake. Therefore, it is possible to provide the label affixing device 100 with high work efficiency.

  Moreover, the label sticking apparatus 100 which concerns on embodiment of this invention will alert | report that a label is issued and a hand sticking is encouraged, when the judgment part 31a judges that the label stuck on an article | item protrudes to the pusher side. . Specifically, the control unit 31 performs processing for prohibiting automatic pasting and displaying “Please paste by hand” on the display screen. In this way, it is possible to prompt the operator (operator) to manually paste.

In addition, the label sticking device 100 according to the embodiment of the present invention includes a display operation unit 4 as an input unit for inputting a signal indicating completion of manual label sticking. When detecting a signal indicating completion of manual label application from the input unit, the label application control unit performs processing for resuming label application processing.
That is, when the operator manually operates the display operation unit 4 such as a button indicating the completion of manual label application after performing manual application on the package, which is an article, the application control unit 31b receives the label from the display operation unit 4. Upon receiving a signal indicating completion of manual pasting, the label pasting process is resumed.
That is, after the operator's label is manually pasted, the automatic label pasting mode by the label pasting unit 41 can be shifted by a simple operation.

  Moreover, in the label sticking apparatus 100 according to the embodiment of the present invention, the label issued by the label issuing unit 40 is a variable length label having a length corresponding to the print item. Even when a variable length label is affixed to an article, the label affixing device 100 prevents the label from sticking out to the pusher and prevents the label from being accidentally affixed to the pusher by performing the above-described process. The label sticking apparatus 100 can be provided.

  When the tray size is set in advance, the determination unit 31a of the control unit 31 determines whether or not the variable length label protrudes from the surface to which the article is attached to the pusher 8 when the tray size and the product information are set. can do. Automatic sticking is prohibited at that time. Specifically, even in the automatic pasting mode, the mode is shifted to the manual pasting mode. Alternatively, the label position is automatically corrected so that the label does not protrude from the surface to be applied of the article to the pusher 8 side. Or, the setting screen appears and manually adjust the label affixing position.

  When the size of the article is detected by the size detection sensor, in this case, the determination process by the determination unit 31a is performed after the tray size is measured.

  In addition, once the label application position is set on the setting screen, the control unit 31 may perform a process of attaching a plurality of labels to the article at the set label position.

  The label sticking device (packaging device) is not limited to the one having the suction portion. For example, the label printer is located above the sticking position and is movably arranged in the horizontal direction. The label sticking position is controlled by moving in the horizontal direction, and the label may be stuck to the article at a predetermined timing by a cylinder movable in the vertical direction, or the label is attached to the article by a compressed air spraying operation. It may be affixed.
