JP4764847B2 - End seal device for horizontal bag making and filling machine - Google Patents

Description

  The present invention relates to an end seal device employed in a horizontal bag making and filling machine.

  In the horizontal bag making and filling machine, in an end seal device that applies an end seal to a tubular film, a pair of seal bodies are driven to rotate in opposite directions, and the seal bodies are fed into the tubular film when meshed. A package is obtained by end sealing and cutting in the direction intersecting with the film transfer direction before and after the article is sandwiched. As described above, the end seal device adopting the rotary seal method is widely used because it is excellent in adaptability to packaging of various articles and can be applied to high-speed packaging.

  However, when the above-described rotary sealing method is employed, the time for which the cylindrical film is held by the sealing body becomes shorter as the transfer speed of the cylindrical film becomes higher. Therefore, when the film transfer speed is set to a high speed, the seal temperature is set to a high temperature or the sealing pressure for holding the tubular film between the sealing bodies in order to prevent the occurrence of defective seals due to changes in the seal state. This can be done by increasing the Similarly, the setting of the seal temperature, the seal pressure, etc., is also changed in response to the package type that requires sealed packaging. However, depending on changes in properties such as the material and thickness of the film, it may not be possible to maintain a good sealing state by changing the setting of the sealing temperature or sealing pressure. In order to reduce the speed, the packaging processing speed is set to a low speed to prevent the occurrence of defective packaging due to poor sealing.

As a proposal that can cope with the above-described problem, there has been proposed a sealing device provided with means for swinging a pair of rotary sealing bodies integrally in the film transfer direction (see, for example, Patent Document 1). According to this sealing device, it is possible to prevent the occurrence of defective sealing even when the film transfer speed is set to be higher than that of an end sealing device employing a conventional rotary sealing method.
Japanese Patent No. 2575774

  However, in the case where the sealing device disclosed in Patent Document 1 is adopted, there are many types of packaging and products with a particularly short packaging length, or processing at a high packaging speed of, for example, 400 pieces / minute or more. Depending on the packaging conditions such as necessary, it is pointed out that the packaging becomes difficult when the seal body is swung. Accordingly, it is necessary to install a plurality of horizontal bag making and filling machines having different specifications depending on the packaging conditions.

And when the 1st seal body 36 and the 2nd seal body 38 which oppose are meshed | engaged, an end seal is given to the cylindrical film F. As shown in FIG. The second seal body 38 is provided with a knife 39 (see FIG. 3) for cutting the tubular film F in the width direction, and the tubular film F is cut at the same time as the end seal is applied. It is configured as follows.

  The first servo motor 48 sets the rotational peripheral speed of the seal bodies 36, 38 to the cylindrical film at the time of engagement of the seal bodies 36, 38 when the end seal is applied to the tubular film F by the pair of seal bodies 36, 38. The rotation is controlled by the control means 46 so as to be the same speed as the transfer speed of F. Further, in one packaging cycle in which the tubular film F is transferred by one packaging length, the speed change is controlled by the control means 46 so that the seal bodies 36 and 38 make one cycle. In addition, after the cylindrical film F is transported by one packaging length, and the sealing bodies 36 and 38 disposed on the rotary shafts 30 and 34 seal the cylindrical film F, the sealing bodies 36 and 38 are next.

That is, in the embodiment, the seal origin position is set to a position rotated by 90 ° from the meshing position where the seal bodies 36 and 38 face each other and are linearly arranged as shown in FIG. 6B. .

  As shown in FIGS. 1 and 2, a rotary shaft 52 is rotatably supported at a position below the first rotary shaft 30 between both side plates 28, 28 of the movable frame body 22. A pair of actuating arms 54 and 54 are disposed at 52 in an axially spaced manner. Each operating arm 54 is rotatably disposed at an eccentric member 53 that rotates eccentrically while rotating integrally with the rotary shaft 52, and the other end rotates around the lower end of the swing frame 32. It is connected freely. A second bracket 56 extending outward from the opening 18 a of the side wall 18 is disposed on the one side plate 28 of the movable frame 22, and rotation control is performed on the second bracket 56 by the control means 46. A second servo motor 58 is provided. The second servo motor 58 is connected to the rotary shaft 52 via the second transmission means 60 comprising a pulley and an endless belt, and the rotary shaft 52 rotates by rotating the second servo motor 58 in one direction. As the operating arms 54 and 54 are moved forward and backward by the eccentric rotation of the eccentric member 53, the swing frame body 32 is configured to swing back and forth in the film transport direction with the first rotating shaft 30 as a fulcrum. . In the embodiment, the rotating shaft 52 and the pair of operating arms 54 and 54 constitute a swing mechanism 62.

  The second servomotor 58 swings the reciprocating frame body 32 (seal bodies 36, 38) one reciprocally as the seal bodies 36, 38 make one cycle according to a preset packaging speed. When the cylindrical film F is end-sealed by both the sealing bodies 36, 38, the control means 46 controls the rotation so that both the sealing bodies 36, 38 swing toward the front side in the film transport direction. The second servo motor 58 is connected to the first servo motor 48 so that the position where the line connecting the shafts of the rotary shafts 30 and 34 becomes perpendicular is the center of the swing range. The rotation is controlled by the control means 46 in synchronization. In the embodiment, the center of the swing range is set as the swing origin position of the swing frame 32.

  As shown in FIG. 1, a first detection member 64 that rotates with the rotation of the first rotation shaft 30 is disposed on the first rotation shaft 30 in the end seal device 10, and is formed on the first detection member 64. The protrusion is detected by first origin signal transmitting means 66 comprising a proximity sensor or the like, and a signal about the seal origin position is output. The rotating shaft 52 of the swing mechanism 62 is provided with a second detecting member 68 that rotates together with the rotating shaft 52, and a protrusion formed on the second detecting member 68 is a second sensor formed of a proximity sensor or the like. The signal is detected by the origin signal transmission means 70, and a signal about the oscillation origin position is output. The detection signals output from both transmitting means 66 and 70 are input to the control means 46.

  The control means 46 shown in FIG. 4 has a storage means 72 for storing various setting data, an input means (operation setting means) 74a capable of setting data by data input or item selection, and a display means 74b for displaying setting data. The touch panel display 74 provided with each of the above is connected, and operation data for various controls such as a packaging speed and a film cut pitch for driving and controlling the horizontal bag making and filling machine can be set. The input means 74a is a swing that swings the seal bodies 36 and 38 (the swing frame 32) by the operation of the swing mechanism 62 in addition to the setting of the operation data for controlling the horizontal bag making and filling machine. The operation and the swing stop operation in which the operation of the swing mechanism 62 is stopped and the seal bodies 36 and 38 (the swing frame body 32) are not swung can be switched and set. The various data values set by the input means 74a can be stored in the storage means 72 for each item of the article 14 and other packaging varieties according to different packaging conditions. Only by performing the setting operation, the previously set data value is read from the storage means 72 and automatically set, and the swing setting values of the seal bodies 36 and 38 set from the storage means 72 can be read. It has become. The product type can be input by inputting an actual product name via the input means 74a or by inputting a product number or the like previously assigned to each product type. In the embodiment, as shown in FIG. 5, an operation button comprising an input means 74 a on a setting screen displayed on the touch panel display 74 for setting the swing operation and the swing stop operation of the seal bodies 36 and 38. By touching, it is configured to be able to switch to the respective operation modes. As described above, in the embodiment, the method of setting the operation by the input means 74a in the touch panel display 74 is adopted, but the operation setting that can be switched by a mechanical changeover switch or the like separately provided from the touch panel display 74 is adopted. It only has to be a means.

  The control means 46 transmits a signal transmitted from the first origin signal transmitting means 66, a pulse transmitted from an encoder attached to the first servo motor 48, and a signal transmitted from the second origin signal transmitting means 70. The current positions of the seal bodies 36 and 38 and the swinging frame body 32 can be recognized by the signal and a pulse transmitted from the encoder attached to the second servo motor 58. When the rocking stop operation is set so that the seal bodies 36 and 38 are not rocked, the rocking frame body 32 is held at the rocking origin position (position shown in FIG. 6B). It is configured.

(Effects of Example)
Next, the operation of the end seal device of the horizontal bag making and filling machine according to the above-described embodiment will be described. Prior to the start of the operation of the horizontal bag making and filling machine, various data for driving and controlling the horizontal bag making and filling machine via the input means 74a and the swing operation for swinging the seal bodies 36, 38 or the swing stop operation. The operation data for controlling the end seal device 10 such as the setting for switching is input and set. The operation data input by the input means 74a is set and stored in the storage means 72 corresponding to each package type determined by the type setting operation by the input means 74a.

  As for the operation mode switching setting, as shown in FIG. 5 (a), a menu screen for setting operation parameters for each product type in the display means 74b is displayed, and an operation setting screen for switching the operation mode. By touching the “swing” operation button on the screen for switching to, the swing operation setting screen of FIG. 5B is displayed. On the swing operation setting screen, the operation mode can be changed by touching one of “use” and “not use” corresponding to any of the swing operation and swing stop operation modes. The set value is stored in the storage means 72 in association with other operation data. Note that the operation mode to be set on the swing operation setting screen by touching the “swing” operation button on the menu screen is set to the state where “use” is touched corresponding to the swing operation as an initial value. Is done.

  When the operation of the horizontal bag making and filling machine is started in the state where the swing operation is set, the end seal device 10 causes the pair of rotary shafts 30 and 34 to be mutually connected by the continuous rotation of the first servo motor 48 in a certain direction. Rotate in the opposite direction. Further, the second servomotor 58 continuously rotates in a fixed direction in synchronization with the first servomotor 48, whereby the swing mechanism 62 is operated, and the swing frame body 32 moves the first rotating shaft 30. It swings back and forth in the film transfer direction as a fulcrum.

  In synchronization with the rotation of the rotary shafts 30 and 34, the swinging frame body 32 is moved in synchronism with the rotation of the pair of seal bodies 36 and 38 toward the downstream side so as to be close to each other on the upstream side in the film transfer direction. It swings downstream in the transfer direction (see FIG. 6A). The pair of seal bodies 36 and 38 sandwiching the tubular film F maintain the sandwiched state of the tubular film F by the swinging of the swinging frame body 32 while rotating and accompany the transfer of the tubular film F. Then, it moves to the downstream side by a required distance, and thereby end sealing and cutting are performed (see FIGS. 6B and 6C). At this time, the swinging frame 32 is swung about the first rotation shaft 30 so that the swinging frame 32 is engaged with the gears 40 and 42 as the swinging frame 32 swings downstream in the film transport direction. The rotational speed of the upper second seal body 38 rotated in the state is lower than the rotational peripheral speed of the lower first seal body 36 in relation to the rocking speed of the rocking frame body 32. Since the seal surface of the second seal body 38 rolls on the seal surface of the seal body 36, it is possible to increase the time for holding the film between the seal bodies 36 and 38.

  The first seal body 36 and the second seal body 38 are separated from each other at a predetermined timing when the seal bodies 36, 38 are moved downstream by the swing of the swing frame body 32 (see FIG. 6C). The package subjected to end sealing and cutting is quickly transferred downstream from the position where the end sealing device 10 is disposed by the carry-out conveyor 16.

  That is, by swinging the swing frame body 32 in which the seal bodies 36 and 38 are disposed back and forth in the film transfer direction, the holding time of the tubular film F by both the seal bodies 36 and 38 can be extended. . Therefore, even if the packaging conditions make it difficult to maintain a good sealing state by changing the setting of the sealing temperature or the sealing pressure, a good sealing state can be obtained without changing the packaging processing speed to a low speed.

  Next, when a package type to be packaged is selected by the swing stop operation by selecting the type by the input means 74a by changing the order, various operation data set and stored in advance for the selected package type are stored. It is read from the storage means 72 and set.

  That is, the end seal device 10 is suitable for the packaging conditions by switching between the rocking operation for rocking the seal bodies 36 and 38 and the rocking stop operation for not rocking depending on the packaging type and other packaging conditions. Can be activated by movement. Further, the setting value for the operation mode operation setting for whether or not to swing the seal bodies 36 and 38 is stored in the storage means 72 corresponding to each packaging type, and is selected when changing the type of the horizontal bag making and filling machine. Therefore, it is not necessary to switch and set the operation mode every time the product type is changed. Therefore, it is possible to shorten the set time associated with the product change at the time of multi-product / small-volume production, and increase the production efficiency.

  When the height of the article 14 is changed due to an order change or the like, the movable handle 22 is moved relative to the fixed machine frame 20 by operating the adjustment handle 26 and operating the height adjusting means 24. By moving vertically up and down, the height position at which the seal bodies 36 and 38 mesh can be set and adjusted to the intermediate position in the height direction of the article 14. Therefore, the end seal position of the film with respect to the article 14 can always be in the middle of the height direction.

1. In the embodiment, the setting value of the operation mode as to whether or not to swing the seal bodies 36, 38 is stored in association with the operation data for each package type, but without being stored in association with the operation data, for example, The set value of the operation mode may be stored regardless of the product type.
2. In the embodiment, whether or not the seal bodies 36 and 38 are to be swung is switched by the input means 74a as the operation setting means based on the judgment result of the operator. The control means 46 oscillates both the sealing bodies 36 and 38 in accordance with the relationship between the rotational speed ratio data in one cycle of the sealing bodies 36 and 38 obtained from the setting data of the speed and the rotational diameter of the sealing bodies 36 and 38. It is most preferable that the rocking operation or the rocking stop operation is automatically switched by the input means 74a according to the determination result. This eliminates the need to set the operation mode each time the model is changed or to set the set value for each type, simplifying the setting and allowing the operator to forget to switch the operation mode. Nor.
3. When the operation of the horizontal bag making and filling machine is stopped, the timing is preferably set such that the pair of seal bodies 36 and 38 stops at a position where they do not contact the film. However, due to the timing of supplying the article 14 from the crossing conveyor 12 into the tubular film F, when the operation of the horizontal bag making and filling machine is stopped, the stop position of the seal bodies 36 and 38 is a position where the seal comes into contact with the film. The heat of the bodies 36 and 38 may stop at a position that adversely affects the film. In such a case, the swing stop position of the seal bodies 36 and 38 is set to a position swung forward or backward in the film transfer direction with respect to the normal position, and the heat of the seal bodies 36 and 38 adversely affects the film. It can also be set as a position that does not affect. That is, the position at which the seal bodies 36 and 38 are separated from the film by the first servo motor 48 that rotates synchronously by swinging the swing frame body 32 to the set swing stop position by the rotation of the second servo motor 58. Rotate to stop. Such a set value of the rocking stop position may be stored in association with the operation data for each package type as in the embodiment.
4). In the embodiment, the seal bodies 36 and 38 are arranged at 180 ° intervals with respect to one rotary shaft 30 and 34. However, the number of seal bodies arranged for one rotary shaft is three even if one. A plurality of the above may be used.
5. In the embodiment, the input unit 74a is provided with the display unit 74b such as a touch panel display. However, any device that can set various data such as a keyboard provided separately from the display unit such as a monitor may be used.
6). In the embodiment, the storage unit 72 is described as being provided in the control unit 46. However, the storage unit 72 may be provided as an independent external storage device.
7). In the embodiment, the configuration that performs the eccentric motion is given as the swing mechanism 62, but if the seal bodies 36 and 38 can swing back and forth in the film transfer direction, for example, a crank mechanism or other configuration is adopted. Can do.
8). In the embodiment, the swing frame body 32 is swung with the first rotation shaft 30 positioned below the film transfer path as a fulcrum, but the second rotation shaft 34 positioned above the film transfer path is supported as a fulcrum. The swing frame body 32 may be configured to swing.
9. When the swing range of the seal bodies 36 and 38 is large, for example, a belt conveyor capable of changing the article conveyance distance is adopted as the crossing conveyor 12 and the carry-out conveyor 16 installed before and after the end seal device 10, and the end seal in the conveyor The pulley on the side close to the apparatus 10 may be configured to move back and forth along with the swinging of the seal bodies 36 and 38 so that the article 14 can be delivered between the conveyors without any trouble.
