  4 and 5 are a front view and a side view showing the structure of the film drawing unit 12. As shown in FIGS. 4 and 5, the film drawing unit 12 includes rollers 12U and 12L and a pair of side plates 12S. The roller 12 </ b> U is attached between the upper ends of the pair of side plates 12, and the roller 12 </ b> L is attached between the lower ends of the pair of side plates 12. Thereby, a space through which the article 100 can pass is provided between the rollers 12U and 12L. Similarly, the transport unit 14 has a structure in which rollers 14U and 14L are respectively attached between the upper end portions and the lower end portions of the pair of side plates.

  6-15 is a figure which shows the packaging operation | movement of the articles | goods by the sealing part 3 in order of a process. The sealing unit 3 includes an upper seal unit 70U and a lower seal unit 70L. The upper seal unit 70U includes seal portions 15U, 16U, and 17U, a cutter 32, and a roller 31. The seal portions 15U, 16U, and 17U are provided corresponding to the seal portions 15L, 16L, and 17L shown in FIG. The cutter 32 is provided in parallel to the seal portions 15U and 16U in the gap between the seal portions 15U and 16U. The upper seal unit 70U can be driven in the vertical direction (Z1 direction and Z2 direction in the drawing) by a drive mechanism (not shown). The seal height adjusting unit 18 can be driven in the vertical direction by a driving mechanism (not shown), and the film drawing unit 12 can also be driven in the vertical direction by a driving mechanism (not shown). Further, the transport unit 14 can be driven in the front-rear direction (X1 direction and X2 direction in the drawing) by a drive mechanism (not shown).

  In the standby state shown in FIG. 6, the film drawing unit 12 is driven downward, and the transport unit 14 is driven forward (that is, when viewed from the front of the apparatus housing). As shown by the thick broken line in the figure, the transparent and strip-like film 50 as the packaging material is a film supply roll 30 → the roller 11 → the upper surface of the mounting table 10 → the roller 13A → the roller 12U → the roller 13B → the roller 14L → the roller 14U. It is laid across a path that contacts the roller 33 and the film collection roll 34 in this order.

  Next, with reference to FIG. 7, the operator places an article 100 that is the current processing target (labeled with 100A in order to be distinguished from the article 100B that is the next processing target) on the mounting table 10. Place on top. In packaging apparatus 1 according to the present embodiment, article 100A can be placed directly on film 50 without using a tray. However, the use of the tray is not necessarily prohibited, and the tray on which the article is placed can be placed on the placement table 10. When the placement of the article 100A on the placing table 10 is completed, the operator presses the start switch 63 (see FIG. 1). The start switch 63 may be a switch (foot switch) of a type that is pressed with a foot.

  When the operator depresses the start switch 63, the film drawing unit 12 is driven upward until the roller 12L is aligned with the rollers 13A and 13B in the same plane with reference to FIG. In conjunction with this, the transport unit 14 is driven rearward (that is, when viewed from the front of the apparatus casing). The transport unit 14 advances toward the back in the space between the upper seal unit 70U and the lower seal unit 70L. At this time, the rotation of the film collection roll 34 is stopped, and the film supply roll 30 supplies the film 50 by a necessary amount. Thereby, the film 50 is conveyed as the conveyance unit 14 advances, and accordingly, the article 100A placed on the film 50 passes from the placement table 10 through the space between the rollers 12U and 12L. Then, it is conveyed onto the seal height adjusting unit 18.

  Next, referring to FIG. 9, the film drawing unit 12 is driven downward. At this time, the rotation of the film collection roll 34 is stopped, and the film supply roll 30 supplies the film 50 by a necessary amount. Thereby, a part of the film 50 used in the next packaging process is stocked in the drawing-in part 6. Thereafter, the worker places the next article 100 </ b> B on the placing table 10. Even if the start switch 63 is pressed by the worker at this time, since the processing for the current article 100A is not completed, the packaging operation for the article 100B enters a standby state.

  Next, referring to FIG. 10, the seal height adjusting unit 18 is driven downward by a predetermined amount corresponding to the thickness of the article 100A. The seal height adjusting unit 18 is driven downward to a position where the heights of the upper surfaces of the seal portions 15L, 16L, and 17L are substantially equal to the center height of the article 100A in the thickness direction. However, as long as the relative position between the article 100A and the seal portions 15L, 16L, and 17L can be adjusted, the lower seal unit 70L may be driven upward instead of driving the seal height adjustment unit 18 downward.

  Next, referring to FIGS. 11 and 12, the transport unit 14 is driven forward in a predetermined posture and track that can avoid contact with the article 100A. Thereby, the transport unit 14 is discharged from the space between the upper seal unit 70U and the lower seal unit 70L, and returns to the initial position shown in FIG. FIG. 16 is a perspective view schematically showing the state of the film 50. Due to the series of operations of the transport unit 14 so far, the film 50 causes the second portion 502 in front of the first portion 501 on which the article 100A is placed (the front in the X1 direction in the drawing) to move the article 100A. It looks like it is folded back in the X2 direction in the figure.

  Next, referring to FIG. 13, when upper seal unit 70U is driven downward, film 50 is sandwiched from above and below by seal portions 15U, 16U, 17U and seal portions 15L, 16L, 17L. And the edge parts of the 1st part 501 and the 2nd part 502 are sealed by thermocompression bonding. FIG. 17 is a diagram schematically showing a sealing portion of the film 50. The side area AR1 is sealed by the seal portions 17U and 17L, and the mouth area AR2 is sealed by the seal portions 16U and 16L. Thereby, the bag body 40 in which the article 100 </ b> A is accommodated is formed between the first portion 501 and the second portion 502. Note that it is not always necessary to seal the three sides of the bag body 40. For example, the sealing of the area AR2 may be suspended, and only two side portions may be sealed. In this case, since the mouth portion of the bag body 40 is opened, the operator can put a seasoning sachet or the like into the bag body 40 after the bag body 40 is discharged from the packaging device 1.

  Further, the film 50 is cut by the cutter 32 along the line N in the vicinity of the area AR2. At the same time, in order to join the films 50 separated by cutting, the area AR3 in the vicinity of the line N is sealed by the seal portions 15U and 15L. Thereby, the film 50 once separated by cutting is joined again at the joint portion 41.

  Next, referring to FIG. 14, the upper seal unit 70U is driven upward to return to the initial position shown in FIG. Thereafter, the seal height adjusting unit 18 is driven upward, and accordingly, the bag body 40 on the seal height adjusting unit 18 is also driven upward.

  Next, referring to FIG. 15, when the belt conveyor of the seal height adjustment unit 18 is driven, the bag body 40 jumps over the seal portion 17 </ b> L from the seal height adjustment unit 18 through the roller 19. Then, it is conveyed onto the belt conveyor 20 of the weighing unit 4. In addition, the film collection roll 34 is driven to wind up the film 50 by a predetermined amount, whereby the joint portion 41 of the film 50 is collected. Thereafter, the seal height adjusting unit 18 is driven downward to return to the initial position shown in FIG. Thereby, the packaging operation similar to the above is started for the next article 100B.

  FIG. 18 is a block diagram illustrating some of the functions of the control unit mounted on the packaging device 1. The control unit includes a setting unit 45 and a storage unit 46. The operator inputs the size (that is, the bag length) of the bag body 40 in the longitudinal direction of the film 50 and the thickness of the article 100 using the operation unit 61 shown in FIG. The input value of the bag length is input to the setting unit 45 as data S1, and the input value of the thickness of the article 100 is input to the setting unit 45 as data S2.

  Based on the data S1, the setting unit 45 draws the film 50 by the film drawing unit 12 (that is, the displacement amount of the film drawing unit 12 from the position shown in FIG. 8 to the position shown in FIG. 9), and the conveyance The conveyance amount of the film 50 by the unit 14 (that is, the displacement amount of the conveyance unit 14 from the position shown in FIG. 7 to the position shown in FIG. 8) is set. The larger the bag length, the larger the pull-in amount and the transport amount, and the smaller the bag length, the smaller the pull-in amount and the transport amount. Specifically, a data table in which the relationship between various bag lengths and appropriate values of the pull-in amount and the conveyance amount corresponding to each bag length is stored in the storage unit 46 in advance, and the setting unit 45 The pull-in amount and the carry amount corresponding to the bag length represented by the data S1 are read from the storage unit 46. The control unit 45 inputs data S <b> 3 relating to the set drawing amount to the driving unit of the film drawing unit 12. Further, the control unit 45 inputs data S <b> 4 regarding the set transport amount to the drive unit of the transport unit 14.

  Further, the setting unit 45 drives the seal height adjustment unit 18 based on the data S2 (that is, the displacement amount of the seal height adjustment unit 18 from the position shown in FIG. 9 to the position shown in FIG. 10). Set. The setting unit 45 sets the drive amount of the seal height adjustment unit 18 to a value that is half the thickness of the article 100 represented by the data S2. The control unit 45 inputs data S5 related to the set drive amount to the drive unit of the seal height adjustment unit 18.

  In the operation of the packaging apparatus 1 described above, when the article 100 is placed on the outer end portion (that is, the end portion close to the roller 11) of the placing table 10 by the operator, the article 100 in the sealing portion 3 is placed. Since the transport amount is insufficient, when the article 100 is sealed with the film 50, the article 100 may bite into the mouth portion of the bag body 40. Referring to FIG. 9, when the article 100 </ b> B is placed on the mounting table 10 by the operator before the downward movement of the film drawing unit 12 is completed, the film drawing unit 12 is moved downward thereafter. Accordingly, there is a possibility that the article 100B moves in the X1 direction and falls from between the rollers 13A and 13B. Hereinafter, measures for avoiding such inconvenience will be described.

  FIG. 19 is a top view illustrating the configuration of the mounting table 10. FIG. 20 is a cross-sectional view showing a cross-sectional structure relating to the position along line KK in FIG. As shown in FIGS. 19 and 20, the mounting table 10 has a structure in which a transparent cover 81 is attached to a box-shaped housing 80 whose upper surface is open. The upper surface of the cover 81 serves as an article placement surface on which the article 100 is placed. In the housing 80, a plurality of reflecting plates 83 extending along the Y direction are arranged in parallel at equal intervals along the X1 direction. Thereby, the internal space of the housing 80 is partitioned into a plurality of strip-like areas M arranged along the X1 direction. In each area M, a predetermined number of light emitting elements 82 (one in this example, but may be plural) are provided. Each light emitting element 82 includes LEDs that emit red, blue, and yellow light, for example. Thus, the mounting table 10 has a structure in which the display unit having the plurality of light emitting elements 82 is embedded in the article mounting surface so as to be visible from the outside. In this display means, the upper surface of the cover 81 is the display surface.

  FIG. 21 is a perspective view showing a part of the structure of the cover 81. The cover 81 includes an electrode film 85 in which a plurality of transparent electrodes 87 extending along the Y direction are arranged in parallel along the X1 direction, and a plurality of transparent electrodes 88 extending along the X1 direction along the Y direction. The electrode films 86 arranged side by side have a structure facing each other via a spacer (not shown). When the article 100 is placed on the placing table 10 (that is, on the cover 81), the transparent electrode 87 and the transparent electrode 88 are electrically connected to each other at the placement location due to the load of the article 100. By detecting the current flowing through the conduction of the transparent electrodes 87 and 88 as an electrical signal, it is possible to detect that the article 100 has been placed on the placement table 10 and the placement location thereof.

  FIG. 22 is a block diagram illustrating a configuration of the control unit 47 provided in the transport apparatus 1. In the control unit 47, a signal S11 indicating information (product code or the like) related to the type or the like of the article 100 to be processed, and a signal S12 indicating that the film drawing unit 12 has drawn the film 50 (see FIG. 9). A signal S13 indicating that the article 100 has been mounted on the mounting table 10 and the mounting position thereof, a signal S14 indicating that the start switch 63 has been pressed, and transport of the film 50 by the transport unit 14 (see FIG. 8) is input. Here, whether or not the drawing of the film 50 by the film drawing unit 12 is completed is determined by, for example, detecting that the film drawing unit 12 has reached the lowest point by an optical sensor, When driven by a stepping motor, it can be determined by counting the number of drive pulses.

  Further, from the control unit 47, a signal S21 for controlling the presence / absence and emission color of each light emitting element 82, a signal S22 for controlling the speaker 64 (see FIG. 1), and an article on the mounting table 10 A signal S23 for adjusting the mounting position of 100 (details will be described later) is output.

  23 to 25 are top views showing examples of control of the display means by the control unit 47. As shown in FIG. 8, when the transport unit 14 starts transporting the film 50 during the processing of the article 100A, the control unit 47 that has received the signal S15 displays the entire area AR10 on the display surface as shown in FIG. Red light is emitted. In this example, red light emission means prohibiting the next article 100 </ b> B from being placed on the placing table 10. In other words, by emitting the display surface in red, the operator is informed that it is now the timing when the placement of the article 100B is prohibited (placement prohibition timing).

  Here, in the case where the operator erroneously places the article 100B on the placement table 10 in spite of the timing at which the display surface emits red light, the control unit that has received the signal S13. In response to the signal S22, a predetermined warning message for causing the worker to collect the article 100B placed thereon, for example, a voice message “Please do not place a product yet” is output from the speaker 64.

  When the processing of the article 100A proceeds and the drawing of the film 50 by the drawing unit 12 is completed as shown in FIG. 9, the control unit 47 that has received the signal S12 uses the signal S21 to set the proper placement position as shown in FIG. The corresponding area AR11 is made to emit blue light, and the other area AR12 is made to emit no light. The size of the area AR11 (the size in the X1 direction) is set in advance according to the type of the article 100 and stored in the storage unit 46, and the control unit 47 refers to the storage unit 46 to obtain a signal. An area AR11 corresponding to the product code included in S11 is set.

  In this example, blue light emission means that the next article 100B is allowed to be placed on the placement table 10, and the position where the article 100B is to be placed. In other words, by causing the display surface to emit blue light, the worker is notified that the placement of the article 100B is currently permitted (placement permission timing), and a partial area of the display surface. By causing the AR 11 to emit blue light, the operator is notified of the position where the article 100B is to be placed. Upon receiving this notification, the worker places the article 100B on the film 50 in the area AR11 emitting blue light, and then presses the start switch 63 to start processing on the article 100B.

  As described above, even if the operator presses the start switch 63 at this time, the process for the current article 100A is not completed, and the packaging operation for the next article 100B is in a standby state. In this case, the control unit 47 that has received the signal S14 causes the entire area AR10 of the display surface to emit yellow light by the signal S21 as shown in FIG. In this example, yellow light emission means that contact with the article 100 </ b> B placed on the placing table 10 is prohibited. That is, by causing the display surface to emit yellow light, the worker is notified that it is currently a timing at which touching the article 100B is prohibited (contact prohibition timing). The yellow light emission state is continued until the transport unit 14 starts transporting the film 50 during the processing of the article 100B after the start switch 63 is pressed to start the process for the article 100B. Therefore, in FIGS. 10-15, the yellow light emission state is continued. When conveyance of the film 50 by the conveyance unit 14 is started, red light is emitted as described above.

  FIG. 26 is a top view illustrating an example of control by the control unit 47 when the article 100B is placed outside the proper placement area. As shown in FIG. 24, if the operator accidentally places the article 100B outside the area AR11 even though the area AR11 on the display surface emits blue light, the control unit 47 places it. The placement position of the article 100B on the placement table 10 is adjusted. Specifically, the control unit 47 specifies an incorrect placement position (a position indicated by a broken line in FIG. 26) of the article 100B based on the signal S13, and moves from the wrong placement position to an appropriate placement position. Calculate the required transport amount. When the film 50 is wound up by a predetermined amount (see FIG. 15) in order to recover the joint portion 41 of the film 50 in the processing of the article 100A, only the necessary conveyance amount is controlled by controlling the driving unit of the film recovery roll 34. Wind up extra film 50. As a result, as shown in FIG. 26, the article 100B moves to the proper placement position on the placement table 10 together with the film 50. Thereafter, the conveyance of the film 50 by the conveyance unit 14 is started. Note that when the placement position of the article 100 on the placement table 10 is adjusted, it is not always necessary to notify the placement position of the article 100.

When the drawing of the film 50 by the drawing unit 12 is completed as shown in FIG. 9, the control unit 47 that has received the signal S12 makes the area AR21 corresponding to the proper placement position blue by the signal S21 as shown in FIG. The other area AR22 is caused to emit no light. The size of the area AR21 (size in the X1 direction and the Y direction) is preset according to the type of the article 100 and stored in the storage unit 46, and the control unit 47 refers to the storage unit 46. Thus, the area AR21 corresponding to the product code included in the signal S11 is set.

  Similarly to the above, the blue light emission means that the next article 100B is allowed to be placed on the placing table 10, and the position where the article 100B is to be placed. That is, by causing the display surface to emit light in blue, the worker is notified that it is now the time when the article 100B is allowed to be placed, and a part of the area AR21 on the display surface is caused to emit blue light. Thus, the position where the article 100B is to be placed is notified to the operator. Upon receiving this notification, the worker places the article 100B on the film 50 in the area AR21 emitting blue light, and then presses the start switch 63 to start processing on the article 100B. Other controls are the same as above.
