  Each embodiment will be described below with reference to the drawings.

(First embodiment)
FIG. 1A is a cross-sectional view illustrating an example of a packaging machine according to the first embodiment.

  For example, by using a combination of a collating machine and an insertion machine, a delivery product in which a subscription paper and an advertisement bundle are combined is produced. Alternatively, by using a collating machine in which a collating machine and an inserting machine are combined, a delivery product in which a subscription paper and an advertisement bundle are combined is made.

  The packaging machine P shown in FIG. 1A wraps two deliveries that are input at the same time or different timings at the same time or different timings. In other words, the packaging machine P is configured to be able to wrap two deliveries that are input at independent timings at independent timings. Therefore, the packaging machine P includes two packaging units that can execute the packaging process independently, that is, the first packaging unit 100 and the second packaging unit 200.

  In this embodiment, a case will be described in which the packaging machine P includes the first packaging unit 100 and the second packaging unit 200 for packaging two deliverables at independent timings. A configuration may be provided in which the delivered items are packaged at independent timings. Further, the packaging object of the packaging machine P is not limited to a delivery item, and any article can be used as long as it can be packaged.

  FIG. 2 is a block diagram showing an outline of control of the packaging machine P shown in FIG. 1A. FIG. 3 is a view for explaining an example of cutting of the packaging film sheet by the pressing mechanism and cutting heater of the packaging machine P shown in FIG. 1A and welding of the packaging film sheet by the pressing mechanism and welding heater. . FIG. 4A is a diagram illustrating an example of a film (bag-shaped film) formed into a bag shape by cutting and welding by the first packaging unit. FIG. 4B is a diagram illustrating an example of a film (bag-shaped film) formed into a bag shape by cutting and welding by the second packaging unit.

  As an example of the packaging machine P shown in FIG. 1A, a vertical packaging machine P in which two delivery items are separately input from above and discharged separately from below will be described. However, the present embodiment is limited to this. It is not a thing. For example, the packaging machine may be a packaging machine that inputs one delivery item from one (side surface), inputs the other delivery item from the other (side surface), and discharges them from below. Moreover, although this embodiment demonstrates the packaging machine P which discharges | emits two delivery items from each discharge port, this embodiment is not limited to this. For example, the packaging machine may have a configuration in which deliveries that are separately input are collectively discharged from one discharge port.

  As illustrated in FIG. 1A, for example, the packaging machine P includes a first packaging unit 100 and a second packaging unit 200. Furthermore, the packaging machine P includes a first heater 13 (heat source) and a second heater 14 (heat source) that are commonly used in the first packaging unit 100 and the second packaging unit 200.

  First, the first packaging unit 100 will be described. The first packaging unit 100 includes an insertion port 101, a first film roller 103, a second film roller 104, a first transport unit 105, a second transport unit 106, a first sensor 107, and a second sensor. 108, a first pressing mechanism 109, a second pressing mechanism 110, a first pressing member 111, a second pressing member 112, a discharge port 115, and an urging member 117. The first transport unit 105 includes a first transport belt 105b, and similarly, the second transport unit 106 includes a second transport belt 106b.

  The input port 101 takes the delivery product into the packaging machine P. The first film roller 103 is configured to be capable of being loaded with a first packaging film roll (film main body) R11 as a packaging material, and supplies the first packaging film sheet S11 from the first packaging film roll R11. To do. Similarly, the second film roller 104 as a packaging material is configured to be capable of being loaded with a second packaging film roll (film body) R12, and the second packaging film roll R12 to the second packaging film sheet. S12 is supplied. That is, the first film roller 103 supplies the first packaging film sheet S11 from the loaded first packaging film roll R11 corresponding to the delivered product, and similarly, the second film. The roller 104 also supplies the second packaging film sheet S12 from the loaded second packaging film roll R12 in response to the delivered product. In other words, the first film roller 103 and the second film roller 104 supply a pair of opposing film sheets (first packaging film sheet S11 and second packaging film sheet S12). The film surface of the first packaging film sheet S11 to be supplied faces the film surface of the second packaging film sheet S12 to be supplied, and the delivered product is the first packaging film sheet S11 to be supplied. And the film surface of the supplied second packaging film sheet S12.

  The first sensor 107 detects a delivery to be taken in and sends a first detection signal to the control unit 11. Similarly, the second sensor 108 detects a delivery to be taken in and sends a second detection signal to the control unit 11. Based on the first and second detection signals, the control unit 11 supplies a drive signal for driving the first pressing mechanism 109 and the second pressing mechanism 110 to the motor 15 and correspondingly. The motor 15 is driven to drive the first pressing mechanism 109 and the second pressing mechanism 110. In the present embodiment, the case where the packaging unit 100 of the packaging machine P includes the two sensors of the first sensor 107 and the second sensor 108 will be described. The movement (movement) of the delivery item is detected by each sensor, and a detection signal is notified to the control unit 11. Thereby, the control part 11 can grasp | ascertain the movement (movement) of the delivery product thrown in, and can drive-control drive systems, such as the motor 15, at an appropriate timing.

  The first pressing mechanism 109 includes a first pressing member (for example, a sponge) 111, and the second pressing mechanism 110 includes a second pressing member (for example, a sponge) 112. The first pressing member 111 is disposed opposite to the first heater (welding and cutting heater) 13 (contact portion 113 a) and moves toward the first heater 13. The second pressing member 112 is disposed to face the second heater (welding heater) 14 (contact portion 114 a) and moves toward the second heater 14. For example, the first heater is higher in temperature than the second heater, and the first heater 13 is one orthogonal to the longitudinal direction of the first packaging film sheet S11 and the second packaging film sheet S12. The second heater 14 is two heaters parallel to the longitudinal direction of the first packaging film sheet S11 and the second packaging film sheet S12.

For example, the first pressing mechanism 109 and the second pressing mechanism 110 are simultaneously driven based on an instruction from the control unit 11. Corresponding to this driving, the first pressing member 111 moves from the standby position toward the first heater 13, and when the first pressing member 111 reaches the first heater 13 (first When the pressing member 111 comes into contact with the first heater 13), the first packaging film sandwiched between the first pressing member 111 and the first heater 13 by the heat of the first heater 13. The sheet S11 and the second packaging film sheet S12 are welded together by the welding line 113b (see FIG. 4A ), and the first packaging film sheet S11 is separated from the first packaging film roll R11 (film body). Thus, the second packaging film sheet S12 is separated from the second packaging film roll R12 (film body).

Further, when the second pressing member 112 moves from the standby position toward the second heater 14 and the second pressing member 112 reaches the second heater 14 (the second pressing member 112 is The first packaging film sheet S11 and the second sheet sandwiched between the second pressing member 112 and the second heater 14 by the heat of the second heater 14 and the second heater 14) The packaging film sheet S12 is welded by a welding line 114b (see FIG. 4A ).

  Note that the second heater 14 can also be used as a welding and cutting heater by increasing the temperature of the second heater 14. Alternatively, the second heater 14 is used as a welding and cutting heater by controlling the operation of the second pressing mechanism 110 and increasing the time during which the second pressing member 112 is in contact with the second heater 14. You can also

  As shown in FIG. 4A, a bag-like film is formed by welding and disconnecting due to contact between the first pressing member 111 and the first heater 13 and welding due to contact between the second pressing member 112 and the second heater 14. 120 is formed. That is, the bag-shaped film 120 is formed by the first packaging film sheet S11 and the second packaging film sheet S12, and is sealed in a bag shape by the welding lines 113b, 113c, and 114b. The bag-like film 120 encloses a delivery item (hereinafter, the bag-like film 120 and the delivery item contained in the bag-like film 120 are collectively referred to as a packaged delivery item).

  Note that one side of the bag-like film 120 is sealed by a welding line 113b formed by welding and separation by contact between the first pressing member 111 and the first heater 13. This welding line 113b becomes the bottom (welding line 113c) of the bag-like film 120 that accommodates the next delivery. Further, both sides of the bag-like film 120 are sealed by a welding line 114b formed by welding due to contact between the second pressing member 112 and the second heater 14.

  For example, in a state where the first pressing member 111 and the first heater 13 are in contact with each other, and the second pressing member 112 and the second heater 14 are in contact with each other, the first conveying belt 105b and the second heating belt 105b are connected to each other. The transport belt 106b is moved, and the packaged delivery product is guided to the discharge port 115 and discharged from the discharge port 115. Further, by the movement of the first conveying belt 105b and the second conveying belt 106b, the first packaging film sheet S11 is pulled out from the first packaging film roll R11, and the first packaging film roll R12 is pulled out from the second packaging film roll R12. The second packaging film sheet S12 is pulled out, and preparations for packaging the next delivery are made.

  Thereafter, the first pressing member 111 returns to the standby position, and the second pressing member 112 similarly returns to the standby position.

  Here, it supplements about the role of the biasing member 117 (for example, elastic bodies, such as a spring). As described above, the film surface of the first packaging film sheet S11 and the film surface of the second packaging film sheet S12 to be supplied face each other, and the delivery is for the first packaging to be supplied. It is taken in between the film surface of the film sheet S11 and the film surface of the supplied second packaging film sheet S12. That is, a delivery is taken in between two opposing film sheets (first packaging film sheet S11 and second packaging film sheet S12). The urging member 117 pushes the first conveyance unit 105 (first conveyance belt 105b) toward the second conveyance unit 106 (second conveyance belt 106b), and draws air between the two-sheet film sheet. Extrude (bleed out air) to make it easy to weld a two-sheet film sheet.

  In the above description, the case has been described in which the packaging machine P wraps a delivery by the first packaging film roll R11 and the second packaging film roll R12. However, the present embodiment is limited to this. It is not a thing. For example, the packaging machine P may wrap the delivery product by inserting the delivery product between the two sheets by a packaging film roll obtained by winding the two-layer film into a roll. In this case, for example, the structure of the heater can be reduced by using the two-layer film roll in which both sides in the longitudinal direction are welded.

  Note that the drawing of the first packaging film sheet S11 and the second packaging film sheet S12 may be performed as follows. For example, when a delivery item is introduced from the insertion port 101, the weight of the delivery unit to be introduced and the force for pushing the delivery item are received at the bottom of the bag-like film 120 (welding line 113c), and the first packaging film sheet S11 and the second packaging film sheet S12 may be pulled out. Note that the drawer described here and the drawer described above (the drawer by moving the first conveyor belt 105b and the second conveyor belt 106b) cooperate with each other to form the first packaging film sheet S11 and the second packaging sheet S11. The packaging film sheet S12 may be pulled out.

  Next, the second packaging unit 200 will be described. The second packaging unit 200 includes an input port 201, a first film roller 203, a second film roller 204, a first transport unit 205, a second transport unit 206, a first sensor 207, and a second sensor. 208, a first pressing mechanism 209, a second pressing mechanism 210, a first pressing member 211, a second pressing member 212, a discharge port 215, and an urging member 217. The first transport unit 205 includes a first transport belt 205b, and similarly, the second transport unit 206 includes a second transport belt 206b. In addition, the 2nd packaging part 200 is substantially the same as the 1st packaging part 100, and detailed description is abbreviate | omitted.

  The first packaging film roll (film body) R21, the second packaging film roll (film body) R22, the first packaging film sheet S21, and the second packaging film sheet S22 are each , Corresponding to the first packaging film roll (film body) R11, the second packaging film roll (film body) R12, the first packaging film sheet S11, and the second packaging film sheet S12. Detailed description will be omitted.

  For example, the first film roller 103, the second film roller 104, the first film roller 203, and the second film roller 204 may be arranged linearly in the horizontal direction. Will grow in size. Therefore, as shown in FIG. 1A, the second film roller 104 and the first film roller 203 are arranged in a straight line or a substantially straight line in the vertical direction. Thereby, it is possible to secure the input port 101 and the input port 201 (the input work space) while suppressing an increase in the size of the packaging machine P.

  Moreover, in the 1st packaging part 100 and the 2nd packaging part 200, the 1st heater 13 and the 2nd heater 14 are utilized in common. Thereby, it can contribute to suppression of a number of parts, and size reduction of the packaging machine P. FIG. For example, as one method for sharing the first heater 13 and the second heater 14, the first heater 13 and the second heater 14 are fixed, and the first pressing member 111 is used as the first heater. 13 (contact portion 113a), the second pressing member 112 is moved relative to the second heater 14 (contact portion 114a), and the first pressing member 211 is moved to the first heater. 13 (contact part 213a), and the second pressing member 212 is moved with respect to the second heater 14 (contact part 214a).

(Second Embodiment)
FIG. 1B is a cross-sectional view illustrating an example of a packaging machine according to the second embodiment. The description will focus on parts that are different from the first embodiment, and description of parts that are common to the first embodiment will be omitted as appropriate.

  As shown in FIG. 1B, the packaging machine P includes a first packaging unit 100 and a second packaging unit 200, and the first packaging unit 100 includes a first heater 113 and a second heater 114. The second packaging unit 200 includes a first heater 213 and a second heater 214.

  In the first embodiment, the first pressing member 111 and the first pressing member 211 are moved, the first heater 13 is fixed, and the second pressing member 112 and the second pressing member 212 are moved. The case where the second heater 14 is fixed has been described. In the second embodiment, for example, the first pressing member 111 is fixed and the first heater 113 is moved, the second pressing member 112 is fixed and the second heater 114 is moved, and the first pressing member 111 is moved. The first heater 213 may be moved while the pressing member 211 is fixed, and the second heater 214 may be moved while the second pressing member 212 is fixed. That is, as long as the distance between the first pressing member 111 and the first heater 113 and the distance between the first pressing member 211 and the first heater 213 can be varied, whichever Such a configuration may be adopted. Similarly, as long as the distance between the second pressing member 112 and the second heater 114 and the distance between the second pressing member 212 and the second heater 214 can be varied, Any configuration may be used.

(Third embodiment)
5A and 5B are diagrams illustrating an example of a cutting heater and a welding heater of a packaging machine according to the third embodiment. The description will focus on parts that are different from the first and second embodiments, and description of parts that are common to the first and second embodiments will be omitted as appropriate.

  As shown in FIG. 5A and FIG. 5B, for example, two second heaters 14 arranged opposite to each other (the two second heaters 14 may be defined as a second heater and a third heater). At least one of the second heaters 14 includes a first divided heater 14-1 and a second divided heater 14-2. The first divided heater 14-1 includes a contact portion 114a-1 and a contact portion 214a-1. The second heater 14-2 includes a contact portion 114a-2 and a contact portion 214a-2.

  For example, as shown in FIG. 5A, the width W1 (distance) of the two second heaters 14 arranged opposite to each other is the width (distance) of the two welding lines 114b (FIG. 4A) on both sides of the bag-like film 120. It corresponds to. That is, the width W1 of the contact portion 114a-1, the contact portion 114a-2, and the contact portion 114a corresponds to the width (distance) of the two welding lines 114b (FIG. 4A) on both sides of the bag-like film 120. Similarly, the width W1 (distance) of the two second heaters 14 arranged opposite to each other corresponds to the width (distance) of the two welding lines 214b (FIG. 4B) on both sides of the bag-like film 220. That is, the width W1 of the contact part 214a-1, the contact part 214a-2, and the contact part 214a corresponds to the width (distance) of the two welding lines 214b (FIG. 4B) on both sides of the bag-like film 220. Thereby, the bag-shaped film 120 and the bag-shaped film 220 of width W1 are obtained.

  For example, as shown in FIG. 5B, the driving force from the motor 16 (heater movable portion) shown in FIG. 2 is transmitted to the heater conveyance mechanism (heater movable portion). One divided heater 14-1 can be moved in parallel to the other second heater 14, and the width W1 can be changed to the width W2. Thereby, the bag-shaped film 120 and the bag-shaped film 220 of width W2 are obtained (the widths of the bag-shaped film 120 and the bag-shaped film 220 can be changed).

  Moreover, about the length (length of the direction orthogonal to the said width | variety) of the bag-like film 120, it can adjust as follows. Here, adjustment of the length of the bag-shaped film 120 will be described, but the length of the bag-shaped film 220 can also be adjusted in the same manner.

  By the movement of the first transport belt 105b and the second transport belt 106b, the first packaging film sheet S11 is pulled out from the first packaging film roll R11, and the second packaging film roll R12 is pulled out of the second packaging film roll R12. The packaging film sheet S12 is pulled out. In addition, based on the first detection signal from the first sensor 107 and the second detection signal from the second sensor 108, the control unit 11 performs the first pressing mechanism 109 and the second pressing mechanism. A drive signal for driving the mechanism 110 is supplied to the motor 15. Therefore, the length of the bag-shaped film 120 is adjusted by adjusting the timing of the drive signal.

  As described above, the width and length of the bag-shaped film 120 and the bag-shaped film 220 can be adjusted.

  The first divided heater 14-1 and the second divided heater 14-2 may be configured by one heater circuit (one heater circuit electrically connected), or two or more heater circuits. You may comprise. For example, the first divided heater 14-1 and the second divided heater 14-2 are configured by one heater circuit, the heater circuit is turned on, and the contact portions 114a-1, 114a-2, 214a-1, and Heat 214a-2. For example, the temperature of the first divided heater 14-1 and the second divided heater 14-2 is heated to the same temperature (high temperature) as that of the first heater.

  In this case, the first divided heater 14-1 is moved by the motor 16 and the heater transport mechanism, and between the first divided heater 14-1 of the one second heater 14 and the other second heater 14. The two-sheet film sheet (the first packaging film sheet S11 and the second packaging film sheet S12) to be supplied in a state where the width of the sheet is adjusted to W2 is the contact portion 114a-1 and the contact portion 114a-. 2 and when the supplied two-sheet film sheet (first packaging film sheet S21 and second packaging film sheet S22) contacts the contact part 214a-1 and the contact part 214a-2. The two-piece film sheet to be supplied is welded and cut at the portions in contact with the contact portion 114a-1 and the contact portion 114a-2, and the two-piece film sheet to be supplied is the contact portion 21. a-1 and the contact portion 214a-2 in contact portions are welded cut. As a result, a W2 bag-like film 120 and a bag-like film 220 are obtained.

  In addition, although the part welded by the contact part 114a-2 and the contact part 214a-2 becomes a cut end and becomes a useless part, it does not exert a bad influence on formation of the bag-like film 120 and the bag-like film 220 of W2.

(Fourth embodiment)
6A and 6B are diagrams illustrating examples of a cutting heater and a welding heater of the packaging machine according to the fourth embodiment. The description will focus on parts that are different from the first to third embodiments, and description of parts that are common to the first to third embodiments will be omitted as appropriate.

  As shown in FIGS. 6A and 6B, for example, at least one second heater 14 of two second heaters 14 arranged to face each other includes a third divided heater 14-3 and a fourth divided heater. 14-4. The third divided heater 14-3 includes a contact portion 114a-3. The fourth heater 14-4 includes a contact portion 114a-4.

  For example, as shown in FIG. 6A, the width W1 (distance) of the two second heaters 14 arranged opposite to each other is the width (distance) of the two welding lines 114b (FIG. 4A) on both sides of the bag-like film 120. It corresponds to. That is, the width W1 between the contact portion 114a-3 and the contact portion 114a corresponds to the width (distance) of the two welding lines 114b (FIG. 4A) on both sides of the bag-like film 120. Similarly, the width W1 (distance) of the two second heaters 14 arranged opposite to each other corresponds to the width (distance) of the two welding lines 214b (FIG. 4B) on both sides of the bag-like film 220. That is, the width W1 between the contact portion 214a-4 and the contact portion 214a corresponds to the width (distance) of the two welding lines 214b (FIG. 4B) on both sides of the bag-like film 220. Thereby, the bag-shaped film 120 and the bag-shaped film 220 of width W1 are obtained.

  For example, as shown in FIG. 6B, the driving force from the motor 16 shown in FIG. 2 is transmitted to the heater conveyance mechanism, and the heater conveyance mechanism moves the third divided heater 14-3 of one second heater 14 to the other. It can move in parallel to the second heater 14, and the width W1 can be changed to the width W2. Thereby, the bag-shaped film 120 of width W2 is obtained (the width of the bag-shaped film 120 can be changed). If the third divided heater 14-3 is moved to change the width W1 to the width W2 and the fourth divided heater 14-4 is not moved, the bag-like film 120 having the width W2 and the bag having the width W1 are moved. A film 220 can also be obtained.

  As described above, the width and length of the bag-shaped film 120 can be adjusted (the length of the bag-shaped film 220 can also be adjusted).

(Fifth embodiment)
7A and 7B are diagrams illustrating examples of a cutting heater and a welding heater of a packaging machine according to a fifth embodiment. The description will focus on parts that are different from the first to fourth embodiments, and description of parts that are common to the first to fourth embodiments will be omitted as appropriate.

  As shown in FIGS. 7A and 7B, for example, the packaging machine further includes a third heater 17 (two second heaters 14 between the two second heaters 14 arranged opposite to each other. When the heater and the third heater are defined, the third heater 17 may be defined as a fourth heater). The third heater 17 includes a contact portion 117a and a contact portion 217a. For example, the length of the contact part 117a and the contact part 217a is shorter than the length of the contact parts 114a and 214a.
