  FIG. 2 is a diagram illustrating an example of the display screen 30 of the display unit 2. In the left half area of the display screen 30, a graphic 40 simulating the outer shape of the bag that is a finished product is displayed. On the figure 40, a figure 41 imitating the first horizontal seal part, a figure 42 imitating the second horizontal seal part, a figure 43 imitating the back sticking part, and a figure 44 imitating the registration mark are displayed. Has been. In addition, the width and length dimensions of the bag body are taught in advance in the packaging machine 1, and these dimensions are displayed in the vicinity of the graphic 40. In the example shown in FIG. 2, the width of the bag is 90 mm, and the length is 140 mm. Further, the width dimension of the back pasting portion is taught in the packaging machine 1 in advance, and this dimension is displayed in the vicinity of the figure 43. In the example shown in FIG. 2, the width dimension of the back pasting portion is 10 mm. In the present embodiment, it is assumed that the bottom of the back pasting portion is located at the center of the back surface of the bag.

  In the right half area of the display screen 30, figures 50 to 55 are displayed. The figure 50 is a figure for selecting front side printing, back side printing, or double sided printing by a touch operation by an operator. Here, surface printing refers to information relating to the article 20 (hereinafter referred to as “article information”) such as the expiration date, expiry date, or serial number, on the surface of the bag (the side on which the back-pasted portion does not exist). Means the process of printing. The back side printing means a process of printing the article information on the back side of the bag (the side on which the back pasting portion exists). Double-sided printing means processing for printing article information on both the front and back surfaces of a bag.

  The figure 51 is a direction indicating figure indicating each of the up, down, left, and right directions. The figure 52 is a figure for selecting, when double-sided printing is selected, either direction instruction setting for front side printing or direction instruction setting for backside printing. When the front side printing (or double-sided printing) is selected, the figure 53 has a width direction (X direction) between the origin (lower left corner) of the figure 40 and the origin (lower left edge) of a print area (figure 80) described later. And the difference distances in the length direction (Y direction). When the back side printing (or double-sided printing) is selected, the figure 54 indicates the difference distances in the X direction and the Y direction between the origin of the figure 40 and the origin (lower left corner) of the print area (figure 60) described later. It is a figure to show. The figure 55 is a figure for determining the print location of the article information on the bag.

  In the state of FIG. 2, the operator first selects front side printing, back side printing, or double sided printing by touching the graphic 50.

  FIG. 3 is a diagram showing an example of the display screen 30 when the reverse side printing is selected in the state of FIG. A graphic 60 is displayed at an arbitrary location on the graphic 40. The figure 60 is a figure showing an area (printing area) on which the article information is to be printed on the back surface of the bag. In the example of FIG. 3, the figure 60 is located at a position where the origin of the figure 60 is deviated from the origin of the figure 40 by 15 mm in the X direction and 40 mm in the Y direction. This shift amount is displayed near the graphic 40 and also as the graphic 54.

  The operator can arbitrarily move the figure 60 in the vertical and horizontal directions within the outer frame of the figure 40 by touching the figure 51.

  FIG. 4 is a diagram showing an example of the display screen 30 in which the graphic 60 is moved from the state of FIG. The figure 60 is moved in the upper right direction from the state of FIG. 3. In the example of FIG. 4, the figure 60 is a position where the origin of the figure 60 is shifted by 60 mm in the X direction and 55 mm in the Y direction with respect to the origin of the figure 40. Is located. Similar to FIG. 3, this deviation amount is displayed near the graphic 40 and also as a graphic 54.

  When the position of the figure 60 on the figure 40 (that is, the print location of the article information on the bag) is determined, the operator determines the position of the figure 60 by touching the figure 55.

  With reference to FIG. 1, the position information (X coordinate and Y coordinate) of the confirmed figure 60 is input from the display unit 2 to the calculation unit 3. Information indicating that the reverse side printing is selected is also input from the display unit 2 to the calculation unit 3. Based on the position information of the figure 60 that has been input, the calculation unit 3 calculates the print location of the article information 72 on the band-shaped packaging material 21 by calculation.

  FIG. 5 is a diagram showing a band-shaped packaging material 21. The packaging material 21 is provided with registration marks 70 at a pitch (140 mm in this example) corresponding to the length of the bag. First, the calculation unit 3 determines the position on the packaging material 21 corresponding to the origin of the figure 40 based on the deviation amount (see FIG. 4) between the origin of the figure 40 and the origin (lower right bottom) of the figure 44 in the X direction and the Y direction. The point 71 is determined. For example, when the amount of deviation between the origin of the figure 40 and the origin of the figure 44 is 55 mm in the X direction and 20 mm in the Y direction, −55 mm in the X direction and −55 mm in the Y direction from the lower right end of the registration mark 70. A point advanced by −20 mm is set as a point 71.

  Next, the calculation unit 3 determines a point 75 on the packaging material 21 corresponding to the origin of the graphic 60 starting from the point 71. In the example of FIG. 4, the origin of the figure 60 is located at a position shifted from the origin of the figure 40 by 60 mm in the X direction and 55 mm in the Y direction. In this case, the calculation unit 3 sets a point advanced from the point 71 by 60 mm in the X direction and 55 mm in the Y direction as a point 75. Here, when the right edge of the packaging material 21 is reached when proceeding in the X direction, it jumps to the left edge. Further, as shown in FIG. 4, when the figure 60 is located on the right side of the figure 43 when viewed from the origin of the figure 40, a distance twice as large as the width of the back pasting portion (in this example, 20 mm) is set. , And add to the distance in the X direction. Therefore, in this example, 60 mm + 20 mm = 80 mm in the X direction from the point 71 (25 mm from the left edge because it reaches the right edge of the packaging 21 at 55 mm), and a point advanced by 55 mm in the Y direction is a point 75 Is set.

  Next, the calculation unit 31 sets an area having the point 75 as the lower left corner, and teaches the printing unit 5 position information of the area. The printing unit 5 prints the article information 72 in the taught area.

  FIG. 6 is a diagram showing an example of the display screen 30 when the front side printing is selected in the state of FIG. A graphic 80 is displayed at an arbitrary location on the graphic 40. The figure 80 is a figure showing an area (printing area) on which article information is to be printed on the surface of the bag. In the example of FIG. 6, the figure 80 is located at a position where the origin of the figure 80 is deviated from the origin of the figure 40 by 15 mm in the X direction and 40 mm in the Y direction. This shift amount is displayed near the graphic 40 and also as the graphic 53.

  The operator can arbitrarily move the figure 80 in the vertical and horizontal directions within the outer frame of the figure 40 by touching the figure 51.

  FIG. 7 is a diagram showing an example of the display screen 30 in which the figure 80 is moved from the state of FIG. The figure 80 is moved in the lower right direction from the state of FIG. 6. In the example of FIG. 7, the origin of the figure 80 is shifted from the origin of the figure 40 by 25 mm in the X direction and 35 mm in the Y direction. Located in the place. Similar to FIG. 6, this deviation amount is displayed near the graphic 40 and also as the graphic 53.

  When the position of the figure 80 on the figure 40 (that is, the print location of the article information on the bag) is determined, the operator confirms the position of the figure 80 by touching the figure 55.

  With reference to FIG. 1, the position information (X coordinate and Y coordinate) of the figure 80 determined is input from the display unit 2 to the calculation unit 3. Information indicating that the front side printing is selected is also input from the display unit 2 to the calculation unit 3. The computing unit 3 obtains the print location of the article information 72 on the band-shaped packaging material 21 by computation based on the input position information of the figure 80.

  FIG. 8 is a view showing a band-shaped packaging material 21. The packaging material 21 is provided with registration marks 70 at a pitch (140 mm in this example) corresponding to the length of the bag. First, the calculation unit 3 determines a point 71 on the packaging material 21 corresponding to the origin of the figure 40. With respect to the X direction, a position shifted from the center of the packaging material 21 to the left by ½ of the width of the bag is defined as the X coordinate of the point 71. In the case of this example, since the width dimension of the bag is 90 mm, the position shifted to the left by 45 mm from the center of the packaging material 21 is set as the X coordinate of the point 71. For the Y direction, the position of the point 71 is determined based on the amount of deviation (see FIG. 6) in the Y direction between the origin of the figure 40 and the origin (lower left corner) of the figure 44. For example, when the deviation amount between the origin of the figure 40 and the origin of the figure 44 is 20 mm with respect to the Y direction, a position advanced by −20 mm in the Y direction from the lower right end of the registration mark 70 Set as coordinates.

  Next, the computing unit 3 determines a point 75 on the packaging material 21 corresponding to the origin of the figure 80 from the point 71 as a starting point. In the example of FIG. 7, the origin of the figure 80 is located at a location shifted from the origin of the figure 40 by 25 mm in the X direction and 35 mm in the Y direction. In this case, the calculation unit 3 sets a point advanced from the point 71 by 25 mm in the X direction and 35 mm in the Y direction as a point 75.

  Next, the calculation unit 31 sets an area having the point 75 as the lower left corner, and teaches the printing unit 5 position information of the area. The printing unit 5 prints the article information 72 in the taught area.

  FIG. 9 is a diagram showing an example of the display screen 30 when double-sided printing is selected in the state of FIG. Graphics 60 and 80 are displayed at arbitrary locations on the graphics 40. The operator can arbitrarily move the figure 60 in the up, down, left, and right directions within the range of the outer frame of the figure 40 by touching the figure 51 after selecting the reverse side printing by the touch operation of the figure 52. When the position of the figure 60 on the figure 40 is determined, the operator determines the position of the figure 60 by touching the figure 55. Further, the operator can arbitrarily move the figure 80 in the up, down, left, and right directions within the range of the outer frame of the figure 40 by touching the figure 51 after selecting surface printing by touching the figure 52. it can. When the position of the figure 80 on the figure 40 is determined, the operator touches the figure 55 to determine the position of the figure 80. Since the processing after the positions of the graphics 60 and 80 are determined is the same as described above, repeated description is omitted.

  FIG. 10 is a diagram showing an example of the display screen 30 when the reverse side printing is selected in the state of FIG. FIG. 3 shows an example in which the graphic 44 is positioned halfway between the upper end and the lower end of the graphic 43. However, when the registration mark 70 is positioned at the lower end of the bag body, it is shown in FIG. Thus, the graphic 44 is positioned at the lower end of the graphic 43. In FIG. 1, the registration mark sensor 4 detects a registration mark 70 on the packaging material 21. Further, the transfer amount of the packaging material 21 can be detected by an encoder (not shown). Therefore, the registration mark 70 can be positioned at the lower end of the bag body by controlling so that the packaging material 21 is laterally sealed at the position where the registration mark 70 is attached.

  FIG. 11 is a diagram showing a band-shaped packaging material 21. The packaging material 21 is provided with registration marks 70 at a pitch (140 mm in this example) corresponding to the length of the bag. Similarly to the above, the calculation unit 3 calculates a point on the packaging material 21 corresponding to the origin of the figure 40 based on the amount of deviation in the X direction and the Y direction between the origin of the figure 40 and the origin (lower right bottom) of the figure 44. 71 is determined. Here, when the registration mark 70 is located at the lower end of the bag body, the Y coordinate of the origin of the figure 44 coincides with the Y coordinate of the origin of the figure 40, and therefore the amount of deviation in the Y direction is zero. is there. Therefore, the Y coordinate of the origin of the registration mark 70 can be adopted as the Y coordinate of the point 71 as it is. Since the subsequent processing is the same as described above, repeated description is omitted. The same applies to the case where front side printing or double sided printing is selected, and repeated description will be omitted.

  As described above, according to the packaging machine 1 according to the present embodiment, the display screen 30 includes the graphic 40 imitating the bag, the graphic 60 and 80 indicating the print area of the article information 72, and the vertical and horizontal directions. A graphic 51 is displayed. When the graphics 60 and 80 are moved on the graphic 40 based on a touch operation of the graphic 51 by the operator, the print location of the article information 72 on the bag is designated. Then, the calculation unit 3 obtains the print location of the article information 72 on the band-shaped packaging material 21 based on the positions of the graphics 60 and 80 on the graphic 40, and the printing unit 5 is designated by the calculation unit 3. The article information 72 is printed on a predetermined portion of the band-shaped packaging material 21.

  Accordingly, the print location of the article information 72 on the bag can be specified by a simple operation of touching the graphic 51 on the display screen 30. Further, since the graphic 51 is a graphic indicating the vertical, horizontal, and horizontal directions, the operator's operation burden can be reduced as compared with the case where the movement amounts of the graphic 60 and 80 are set by numerical input. The printing unit 5 performs printing on the band-shaped packaging material 21 before bag-making, but the display screen 30 is not a figure imitating the band-shaped packaging material 21 before bag-making, but a bag after bag-making. A figure 40 imitating the body is displayed. Then, in order to move the figures 60 and 80 on the figure 40 imitating the bag body, the operator prints on an appropriate portion of the bag body while visually checking the overall balance of the bag body which is the form of the final product. You can specify the location. In addition, the calculation unit 3 calculates the print location of the article information 72 on the band-shaped packaging material 21 based on the positions of the figures 60 and 80 on the figure 40. Therefore, it is possible to avoid a situation in which the article information 72 is printed at a location different from the location specified on the display screen 30.

  Moreover, according to the packaging machine 1 which concerns on this Embodiment, the calculating part 3 is the information regarding the position of the origin of the figure 40, the information regarding the position of the origin of the figures 60 and 80, the information regarding the width dimension of a bag, Based on the information on the width dimension of the back pasting portion, the print location of the article information 72 in the width direction (X direction) of the band-shaped packaging material 21 is obtained. Thereby, the calculating part 3 can calculate correctly the printing location (especially printing location about X direction) of the article information 72 in the strip | belt-shaped packaging material 21. FIG.

  Moreover, according to the packaging machine 1 which concerns on this Embodiment, it can select front surface printing or back surface printing (that is, a printing surface can be selected), and the calculating part 3 is the information regarding the position of the origin of the figure 40, and a figure. Based on the information on the positions of the origins 60 and 80, the information on the width of the bag, the information on the width of the back-pasted portion, and the information on the selection of the print surface, the X-direction of the band-shaped packaging material 21 The print location of the article information 72 is obtained. As a result, not only when the article information 72 is printed on the back surface (the surface on the side where the back-pasted portion is present) of the bag body, but also when printing on the front surface (the surface where the back-pasted portion is not present). The unit 3 can accurately calculate the print location of the article information 72 (particularly the print location in the X direction) on the band-shaped packaging material 21.

  Moreover, according to the packaging machine 1 which concerns on this Embodiment, the registration mark 70 is attached | subjected to the strip | belt-shaped packaging material 21 with the pitch corresponding to the length dimension of a bag body, A graphic 44 simulating the registration mark 70 is displayed on the graphic 40. Then, the calculation unit 3 determines the length of the band-shaped packaging material 21 based on the information on the origin position of the graphic 40, the information on the origin positions of the graphics 60 and 80, and the information on the origin position of the graphic 44. The print location of the article information 72 in the vertical direction (Y direction) is obtained. Thereby, the calculating part 3 can calculate correctly the printing location (especially printing location about a Y direction) of the article information 72 in the strip | belt-shaped packaging material 21. FIG.

  Further, according to the packaging machine 1 according to the present embodiment, as shown in FIGS. 10 and 11, the registration mark 70 is attached to the band-shaped packaging material 21 at a pitch corresponding to the length dimension of the bag. Thus, the bag-shaped packaging material 21 is cut at a location where the registration mark 70 is attached. And the calculating part 3 is the article | item information about the length direction (Y direction) of the strip | belt-shaped packaging material 21 based on the information regarding the position of the origin of the figure 40, and the information regarding the position of each origin of the figures 60 and 80. 72 print positions are obtained. In this case, since the position of the registration mark 70 is fixed to the lower end (or the upper end) of the bag, no information on the position of the registration mark 70 is required when the calculation unit 3 calculates the print location. Accordingly, it is possible to reduce the processing load on the calculation unit 3.

  Moreover, according to the packaging machine 1 which concerns on this Embodiment, double-sided printing can be selected, and in that case, the figure 80 for front surface printing and the figure 60 for back surface printing are displayed on the display screen 30. . Then, based on the touch operation of the graphics 51 and 52 by the operator, the front-side printing figure 80 moves on the figure 40, whereby the printing location of the article information 72 on the front surface of the bag is designated, and the back-side printing is performed. When the figure 60 moves on the figure 40, the printing location of the article information 72 on the back surface of the bag is designated. As a result, even when the article information 72 is printed on both the front and back surfaces of the bag, the operator's operation burden can be reduced as in the case of printing only on one side.

  Moreover, according to the packaging machine 1 which concerns on this Embodiment, as shown, for example in FIG. 3, the figure 40 and the figure 51 are displayed on the different area | region (area | region which does not overlap) in the display screen 30. FIG. Accordingly, since the graphic 51 is not displayed on the graphic 40 in an overlapping manner, the display of the graphic 51 becomes a hindrance when the graphic 60, 80 is moved on the graphic 40 for designating the print location. Can be avoided.
