FIG. 4B is a view showing an example of a film (bag-like film) formed in 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 will be described in which two deliverables are separately fed from above and discharged from below separately, but the present embodiment is limited to this. It is not a thing. For example, the packaging machine may be a packaging machine in which one delivery is loaded from one side (side) and the other delivery is loaded from the other (side) and each is discharged from below. Moreover, although this embodiment demonstrates the packaging machine P which discharges two deliveries from each discharge port, this embodiment is not limited to this. For example, the packaging machine may be configured to collectively deliver separately input deliveries from one outlet.

  As shown 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) 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 input port 101, a first film roller 103, a second film roller 104, a first conveyance unit 105, a second conveyance 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 a biasing member 117. The first conveyance unit 105 includes a first conveyance belt 105b, and similarly, the second conveyance unit 106 includes a second conveyance belt 106b.

  The inlet 101 takes in the delivery into the interior of the packaging machine P. The first film roller 103 is configured to be able to load 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. Do. Similarly, the second film roller 104 as a packaging material is configured to be able to load a second packaging film roll (film main body) R12, and the second packaging film roll R12 to the second packaging film sheet are configured. Supply S12. 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 taken-in delivery, and similarly, the second film The roller 104 also feeds the second wrapping film sheet S12 from the loaded second wrapping film roll R12 in response to the taken-in delivery. In other words, the first film roller 103 and the second film roller 104 supply the facing two-sheet film sheet (the first packaging film sheet S11 and the 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 deliverable 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. The control unit 11 supplies drive signals for driving the first pressing mechanism 109 and the second pressing mechanism 110 to the motor 15 based on the first and second detection signals, and corresponds to this. The motor 15 is driven and the first pressing mechanism 109 and the second pressing mechanism 110 are driven. 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, but in practice three or more sensors are provided. The movement (movement) of the delivery is detected by each sensor, and a detection signal is notified to the control unit 11. As a result, the control unit 11 can grasp the movement (movement) of the input delivery and can drive and control the drive system of the motor 15 or the like 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 to face the first heater (heater for welding and cutting) 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 at a higher temperature than the second heater, and the first heater 13 is one that is orthogonal to the longitudinal direction of the first packaging film sheet S11 and the second packaging film sheet S12. The second heaters 14 are 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. When the first pressing member 111 moves from the standby position toward the first heater 13 and the first pressing member 111 reaches the first heater 13 in response to this driving (a The first packaging film sandwiched between the first pressing member 111 and the first heater 13 by the heat of the first heater 13 when the pressing member 111 contacts the first heater 13) The sheet S11 and the second packaging film sheet S12 are welded at the welding line 113b (see FIG. 4A ), and the first packaging film sheet S11 is separated from the first packaging film roll R11 (film main body). 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 The first packaging film sheet S11 and the second film sheet S11 which are sandwiched between the second pressing member 112 and the second heater 14 by the heat of the second heater 14). And the packaging film sheet S12 are welded at a welding line 114b (see FIG. 4A ).

  The second heater 14 can also be used as a welding / cutting heater by raising the temperature of the second heater 14. Alternatively, the second heater 14 is used as a welding / cutting heater by controlling the operation of the second pressing mechanism 110 and prolonging the time for which the second pressing member 112 is in contact with the second heater 14 You can also

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

  Note that one side of the bag-like film 120 is sealed by a welding line 113 b formed by welding and separation by the contact of the first pressing member 111 and the first heater 13. The welding line 113b is the bottom (welding line 113c) of the bag-like film 120 for containing the next delivery. Moreover, the both sides of the bag-like film 120 are sealed by the welding line 114b formed of the welding by the contact of the 2nd pressing member 112 and the 2nd heater 14. As shown in FIG.

  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 The transport belt 106 b is moved, and the packaged delivery is guided to the discharge port 115 and discharged from the discharge port 115. In addition, the first packaging film sheet S11 is pulled out of the first packaging film roll R11 by the movement of the first transport belt 105b and the second transport belt 106b, and the first packaging film roll R12 The second packaging film sheet S12 is pulled out and is ready to be packaged for the next delivery.

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

  Here, the role of the biasing member 117 (for example, an elastic body such as a spring) will be supplemented. As described above, the film surface of the first packaging film sheet S11 faces the film surface of the supplied second packaging film sheet S12, and the delivery is for the first packaging film 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 the facing two-sheet film sheet (the first packaging film sheet S11 and the second packaging film sheet S12). The biasing member 117 pushes the first conveyance unit 105 (the first conveyance belt 105b) toward the second conveyance unit 106 (the second conveyance belt 106b), and the air between the two-sheet film sheet is Extruding (withdrawing air) to facilitate welding of the two-sheet film sheet.

  In the above description, the case where the packaging machine P packages a delivery by the first packaging film roll R11 and the second packaging film roll R12 has been described, but the present embodiment is limited to this. It is not a thing. For example, the packaging machine P may insert the delivery between the two sheets and package the delivery by a packaging film roll in which the two sheets of film are wound in a roll. In this case, for example, the configuration of the heater can be reduced by using one in which both longitudinal sides of the two-layered film roll are welded.

  The following may be applied to the withdrawal of the first packaging film sheet S11 and the second packaging film sheet S12. For example, when a delivery is loaded from the loading port 101, the weight of the delivery section to be loaded and the force for pushing the delivery are received by the bottom side (welding line 113c) of the bag-like film 120, and the first packaging film sheet S11 and the second packaging film sheet S12 may be pulled out. The first packaging film sheet S11 and the second packaging film S11 cooperate with the above-described drawer and the above-described drawer (the first conveyor belt 105b and the second conveyor belt 106b moving movably) in cooperation with each other. The packaging film sheet S12 may be pulled out.

  Subsequently, 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 conveyance unit 205, a second conveyance 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 a biasing member 217. The first conveyance unit 205 includes a first conveyance belt 205b, and similarly, the second conveyance unit 206 includes a second conveyance belt 206b. The second packaging unit 200 is substantially the same as the first packaging unit 100, and the detailed description will be omitted.

  The first packaging film roll (film main body) R21, the second packaging film roll (film main body) R22, the first packaging film sheet S21, and the second packaging film sheet S22 are respectively The first packaging film roll (film main body) R11, the second packaging film roll (film main body) R12, the first packaging film sheet S11, and the second packaging film sheet S12 Yes, detailed description is 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. The size of will increase. Therefore, as shown in FIG. 1A, the second film roller 104 and the first film roller 203 are arranged linearly or substantially linearly in the vertical direction. Thereby, the input port 101 and the input port 201 (input working space) can be secured while suppressing the expansion of the size of the packaging machine P.

  Further, in the first packaging unit 100 and the second packaging unit 200, the first heater 13 and the second heater 14 are used in common. This can contribute to the reduction of the number of parts and the miniaturization of the packaging machine P. For example, as a method for making the first heater 13 and the second heater 14 common, the first pressing member 111 is fixed to the first heater with the first heater 13 and the second heater 14 fixed. 13 (contact portion 113a), and the second pressing member 112 is moved with respect to the second heater 14 (contact portion 114a), and the first pressing member 211 is moved to the first heater. 13 (contacting portion 213a), and the second pressing member 212 is moved relative to the second heater 14 (contacting portion 214a).

Second Embodiment
FIG. 1B is a cross-sectional view showing an example of a packaging machine according to a second embodiment. The description will focus on the parts different from the first embodiment, and the description of the parts 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. 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 move, the first heater 13 is fixed, and the second pressing member 112 and the second pressing member 212 move. 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, and the second pressing member 112 is fixed and the second heater 114 is moved. The pressing member 211 may be fixed and the first heater 213 may be moved, and the second pressing member 212 may be fixed and the second heater 214 may be moved. 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 changed, It may be of such a configuration. Similarly, if 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, It may have any configuration.

Third Embodiment
5A and 5B are views showing an example of a cutting heater and a welding heater of a packaging machine according to a third embodiment. Description will be made focusing on parts different from the first and second embodiments, and description of parts in common with the first and second embodiments will be appropriately omitted.

  As shown in FIGS. 5A and 5B, for example, two second heaters 14 arranged opposite to each other (these two second heaters 14 may be defined as a second heater and a third heater) At least one of the second heaters 14 is composed of 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 also 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 disposed 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 and 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 disposed 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 portion 214a-1 and the contact portion 214a-2 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-like film 120 of width W1 and the bag-like film 220 are obtained.

  For example, as shown in FIG. 5B, the driving force from the motor 16 (heater movable part) shown in FIG. 2 is transmitted to the heater conveyance mechanism (heater movable part), and the heater conveyance mechanism is the second one of the second heaters 14. One division 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-like film 120 and the bag-like film 220 of width W2 are obtained (the widths of the bag-like film 120 and the bag-like film 220 can be changed).

  Further, the length of the bag-like film 120 (the length in the direction orthogonal to the width) can be adjusted as follows. In addition, although adjustment of the length of the bag-like film 120 is demonstrated here, the length of the bag-like film 220 can be adjusted similarly.

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

  Thus, the width and the length of the bag-like film 120 and the bag-like 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. It may consist of For example, the first divided heater 14-1 and the second divided heater 14-2 are formed by one heater circuit, and the heater circuit is turned on to form the contact portions 114a-1, 114a-2, 214a-1, and Heat 214a-2. For example, the temperatures of the first divided heater 14-1 and the second divided heater 14-2 are heated to the same temperature (high temperature) as the first heater.

  In this case, the first divided heater 14-1 is moved by the motor 16 and the heater conveyance mechanism, and between the first divided heater 14-1 of one second heater 14 and the other second heater 14 The two-piece film sheet (the first packaging film sheet S11 and the second packaging film sheet S12) supplied in a state where the width of the sheet W is adjusted to W2, the contact portion 114a-1 and the contact portion 114a- When the two sheets of film sheets (the first film sheet for packaging S21 and the second film sheet for packaging S22) in contact with the sheet 2 and supplied are in contact with the contact portion 214a-1 and the contact portion 214a-2 In the supplied two-sheet film sheet, the portions in contact with the contact portion 114a-1 and the contact portion 114a-2 are welded and cut, and the supplied two-sheet film sheet has the contact portion 21. a-1 and the contact portion 214a-2 in contact portions are welded cut. As a result, a bag-like film 120 and a bag-like film 220 of W2 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 an unnecessary 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 showing an example of a cutting heater and a welding heater of a packaging machine according to a fourth embodiment. The description will focus on parts different from the first to third embodiments, and the description of parts in common with the first to third embodiments will be omitted as appropriate.

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

  For example, as shown in FIG. 6A, the width W1 (distance) of the two second heaters 14 disposed 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-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 disposed 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 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-like film 120 of width W1 and the bag-like film 220 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 is configured to transmit the third divided heater 14-3 of one second heater 14 to the other. It can be moved parallel to the second heater 14 and the width W1 can be changed to the width W2. Thereby, the bag-like film 120 of width W2 is obtained (the width of the bag-like film 120 can be changed). If the third division heater 14-3 is moved to change the width W1 to the width W2 and the fourth division heater 14-4 is not moved, the bag-like film 120 of width W2 and the bag of width W1 are used. Film 220 can also be obtained.

  Thus, the width and length of the bag-like film 120 can be adjusted (the length of the bag-like film 220 can also be adjusted).

Fifth Embodiment
7A and 7B are views showing an example of a cutting heater and a welding heater of a packaging machine according to a fifth embodiment. The description will focus on parts different from the first to fourth embodiments, and the description of parts in common with 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 as a second heater) between the two second heaters 14 disposed opposite to each other. When the heater and the third heater are defined, the third heater 17 may be defined as the fourth heater). The third heater 17 includes a contact portion 117a and a contact portion 217a. For example, the lengths of the contact portion 117a and the contact portion 217a are shorter than the lengths of the contact portions 114a and 214a.

  For example, as shown in FIG. 7A, the width W1 (distance) of the two second heaters 14 disposed 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. And the width (distance) of the two welding lines 214 b (FIG. 4B) on both sides of the bag-like film 220. That is, the width W1 of the two contact portions 114a corresponds to the width (distance) of the two welding lines 114b (FIG. 4A) on both sides of the bag-like film 120, and the width W1 of the two contact portions 214a is bag-like This corresponds to the width (distance) of the two welding lines 214 b (FIG. 4B) on both sides of the film 220.
