[0003] In a conventional vertical bag-making filling and packaging method for providing a vertical seal of an envelope-attached type, a continuous bag film is passed between a bag-making machine and a product drop-filling cylinder, and the bag-making film is bent by the folding action of the bag-making machine. Is folded into a cylinder to wrap the product drop filling cylinder, and both edges of the bag film are overlapped by the vertical seal allowance at the front side of the product drop filling cylinder, and a vertical heater support arm that can freely approach and separate from the product drop filling cylinder is provided. The two edges of the bag film are welded by the vertical heater in the form of a bar to seal the envelope in the form of a vertical seal to form a packaging cylinder, which is fed out downward. The package is dropped and filled, and a required lower portion and a required upper portion of the package are horizontally sealed, respectively. The vertical heater (rod-shaped heater) is separated from the product drop-filling cylinder by an air cylinder. The process of intermittently feeding the bag film from the bag by the pitch of one bag, and the process of pressing the envelope-attached vertical heater against the product drop-fill tube to heat seal the overlap between the edges of the bag film alternately. there were.

As described above, since the bag film is conventionally intermittently fed, vibration and noise are large and the feeding speed of the bag film cannot be increased. For this reason, it is desired to provide a technique capable of continuously feeding a bag film and applying an envelope-attached vertical seal.

[0005] In the conventional vertical bag making and filling machine, the reason why the bag film could not be continuously fed and packed was that the vertical bag making and filling machine mainly packs bulk materials, The dispensers before appearing had very low dosing capacity and, in addition, the dosing was frequently paused 5 or 6 times per minute. For this reason, the vertical bag making / filling / packaging machine has a low packaging capacity, and the metering / supply has been frequently stopped. On the other hand,
When there is a pause in metering, no driving technique has been established to stop the film feeding and avoid the generation of waste paper. For this reason, it is necessary to avoid the occurrence of waste paper by not performing film feeding when there is a pause in metering as intermittent feeding instead of continuous feeding of the bag film. Since the width of the bag is large in the vertical bag making and filling machine, if the rotary cutter is used as the horizontal sealing means, there is a disadvantage that the rotary cutter must be extremely large, so the rotary cutter has not been employed. And
Since the conventional horizontal sealing means opens and closes a pair of bar heaters with an air cylinder, it is difficult to cope with the operation unless the bag film is intermittently fed. That is the point.

On the other hand, at present, there is provided a high-performance weighing machine which has sufficiently high weighing capacity and greatly reduces halting of weighing and feeds, and feeds a film when weighing is halted. A driving technique for stopping and avoiding generation of waste paper has been established. Further, the technology of box motion type horizontal sealing means driven by a servomotor which is practically used in a horizontal bag making and filling machine (for example, Japanese Patent No. 1559789; Japanese Patent Publication No. 1-46374, Japanese Patent Application No. 1-248629). A technology that can be diverted to a vertical bag making and filling machine has been established.

In a conventional vertical bag making and filling machine,
As the reason why the envelope-sealed vertical seal could not be performed by continuously feeding the bag film, in addition to the reasons described above,
Even if you press the heat seal bar for vertical sealing against the product drop filling cylinder and slide the bag film to perform vertical sealing,
It is difficult to obtain precise surface contact by keeping the contact surfaces of the heat seal bar and the product drop filling cylinder parallel with high precision. In addition, the vertical seal may be defective due to insufficient heat, or the feeding of the bag film may not be possible due to the failure to obtain an appropriate clamping force. Even if the vertical sealing heat seal bar is pressed against the product drop filling cylinder and the bag film is slid to perform vertical sealing, it is necessary to have a technique for avoiding the generation of waste paper. That is the point.

[0008] The technique of performing vertical sealing of the seal tape-bonded type disclosed in Japanese Patent Application Laid-Open No. 49-118595 cannot adjust the both edges of the bag film to be exactly abutted with no gap, so that both edges of the bag film are separated. It is inevitable that they will overlap or overlap.

First, the use of a roll heater as a vertical heater was considered. As a result, when the envelope was stuck with the roll heater, the heat transfer amount was insufficient, and the sealing failure occurred.
This is due to the fact that the vertical type bag making / filling / packaging machine requires a thicker film and a higher sealing strength than the horizontal type bag making / filling / packaging machine. Next, with reference to Japanese Patent Application Laid-Open No. 49-118595, a rod-shaped heater was employed as a vertical heater, and it was considered that a bag film being moved was slid between itself and a product drop filling cylinder (Japanese Patent Application No. Hei. -151121). As a result of the trial run of the prototype machine, the bar heater did not contact the bag film being moved over the entire length, but was unevenly contacted, resulting in poor sealing. It is extremely difficult to pinch in a good contact state while maintaining the parallelism with high precision over a wide range. If the heater temperature is too high, the film seal surface of the bag will be distorted, while if the heater temperature is low, either the sealing will be incomplete or the film film feed rate must be reduced, and the vertical heater will be temperature controlled. It cannot be necessary and sufficient to fine-tune the heat transfer amount according to the type of bag film. Fine adjustment of the film clamping pressure between the vertical heater and the product drop filling cylinder could not be performed at all, and the biasing force was biased to either excessively or insufficiently, and a moderate clamping pressure that allowed the bag film to slide well If the film holding force is large, the film for the bag cannot be fed. When the rod-shaped heater was separated from the bag film when the bag film feed was stopped, it was found that the joining portion of both edges of the bag film was opened.

The continuous bag film W is passed between the bag making device 2 and the product drop filling tube 1, and the bag film W is bent into a cylinder by the bending action of the bag making device 2 to wrap the product drop filling tube 1. Then, when performing packaging for applying an envelope-attached vertical seal, both edges of the bag film W are overlapped on the front side of the product drop filling cylinder 1 by a vertical seal margin. Also, when performing packaging for applying a vertical seal of the sealing tape-sealed type, both edges of the bag film W are butted on the front side of the product drop filling cylinder 1 and both sides are heat-soluble inside the butted portion. Is introduced from the front side of the bag making device 2. Subsequently, the vertical heater support arm 3 is brought close to the product drop filling cylinder 1. Then, the film pressing plate 5 suppresses the vicinity of both sides of the overlapped portion of both ends of the bag film W toward the product drop filling cylinder 1, and the top of the bow of the film pressure bonding band spring 6 comes into contact with the film pressing plate 5. And flatten, and a film clamping pressure is generated. Further, when the vertical heater support arm 3 is brought close to the product drop filling cylinder 1, the film pressure feed roll 7 cooperates with the floating roller 8 to sandwich the bag film W. In this case, after adjusting the bow-like curvature of the film-bonding band leaf spring 6 and adjusting the vertical heater support arm 3 close to the product drop filling cylinder 1,
The pressing of the vertical heater 4 against the band spring 6 for film pressing is performed. In the case of applying a vertical seal of the sealing tape-sealed type, the distance between the film pressing surface of the film holding plate 5 and the film compression band spring 6 from the product drop filling cylinder 1 is determined by the distance between both edges of the bag film W. Are finely adjusted so that they abut each other without any gap at the front side of the product drop filling cylinder 1.
When the packaging operation is performed, the film heater for the bag is fed, and the vertical heater 4 preheated to the required temperature presses the band spring 6 for the film crimping to pinch the mating portion of both edges of the film W for the bag, The film pressing plate 5 lightly presses both side portions of the matching portion of both edges of the bag film W, and the vertical heater 4 applies an envelope-sealed vertical seal or seal tape to the overlapping portions of both ends of the bag film W. The shape will be sealed vertically. The overlapping portion of the bag film edges is sandwiched between the vertical heater 4 and the film-bonding band leaf spring 6 for a fixed section, heated to a temperature at which welding can be performed by the vertical heater 4, and the press-sealing is performed sufficiently and sufficiently. The film is then sandwiched between the film pressing feed roll 7 and the floating roller 8 which are moved and passed and subsequently driven to rotate, so that the holding of the bag film does not stop due to the pressing force between the vertical heater 4 and the film pressing band spring 6. As described above, the pressure bonding is completely performed while the auxiliary feeding is performed, so that the heat sealing without distortion on the sealing surface is performed. When a situation occurs in which the material to be packaged is not supplied from the metering machine during operation and the vertical heater 4 is separated from the film-bonding band spring 6 in order to prevent useless paper, the bag film W is fed. Stops, and the film pressure feed roll 7 stops rotating, and the film pressing plate 5 and the film pressure band spring 6 continuously press both edges of the bag film W in the same state. Since the deformation of the top of the bow shape is maintained, the mating portions at both ends of the bag film W will not be violated, and a good vertical seal will be continued when the operation is performed again.

The quality of the vertical seal is determined by the amount of heat transferred from the vertical heater 4 to the bag film W per unit area. If the amount of heat transfer is excessive, the film surface is melted and the sealing surface is loosened. If the amount of heat transfer is insufficient, a poor seal will result. In the present invention, the amount of heat transferred to the bag film W by the vertical heater 4 is determined as a function of the type of the film, the film clamping pressure, the vertical heater temperature, the film feed speed, and the film heater contact length. Therefore, in the present invention, in addition to being able to adjust the type of the film, the vertical heater temperature, and the film feeding speed, it is possible to finely adjust the film clamping pressure and the contact length of the film heater as desired. In order to perform the vertical sealing satisfactorily, it is preferable that the adjustment of the pressing of the film pressing plate 5 and the vertical heater 4 against the band spring 6 for film pressing is the same. Vertical heater 4 and strip spring 6 for film crimping
The pressing force of the bag film W is ensured by a required length, and a proper pressing force required for sealing can be secured.
To ensure smooth sliding between the film and the band spring 6 for film crimping. When the temperature of the vertical heater 4 is too high or too low, the temperature of the vertical heater 4 is adjusted. Vertical heater 4
When the temperature is appropriate but the pressure seal is not sufficient, the fine adjustment movement of the double bracket 10 in the direction of the product drop filling cylinder 1 is performed. Then, the length of the linear contact portion between the vertical heater 4 and the film-bonding band leaf spring 6 is increased, so that the heat welding time can be slightly increased, and the clamping pressure increases. Done. If the temperature of the vertical heater 4 is appropriate and the pressure seal is performed excessively, the product drop filling cylinder 1
When the fine adjustment movement is performed in the direction away from the film, the length of the linear contact portion between the vertical heater 4 and the band spring 6 for film crimping becomes small, and the heat welding time is slightly shortened, and the pinching pressure is reduced. Since the rolling pressure of the feed roll 7 and the floating roller 8 does not fluctuate, the pressure-bonding seal is performed well.

Then, the bag film feed belt device 11
Continuously feeds the bag film W, and operates the actuator 9 so that the vertical heater 4 slidably contacts the film pressing band spring 6 with an appropriate pressure.
And the idler roller 8 performs auxiliary film feed for the bag. Both edges of the bag film W and the seam sealing tape T are slid and heat-transferred while being sandwiched between the bar-shaped vertical heater 4 and the film pressure-bonding strip spring 6, and welded. In the vicinity of the lower side, the bag film W is sealed by pressure while being provided with an auxiliary feed to the bag film W by the film pressure feed roll 7 and the floating roller 8. Then, the bag film W is sealed vertically at both edges thereof with a seam sealing tape T to form a packaging tube H, which is fed out downward. It is dropped and filled at predetermined time intervals, and a horizontal sealing and cutting device (not shown) horizontally seals a required lower part and a required upper part of the packaged object of the packaging tube H, respectively. If the temperature of the vertical heater 4 is too high or too low, the temperature of the vertical heater 4 is adjusted. However, adjusting the temperature of the vertical heater 4 does not adjust the heating time. Therefore, when the heating time is short and the welding temperature does not reach the welding temperature while the temperature of the vertical heater 4 is appropriate and the pressure bonding seal is insufficient, a fine adjustment movement is performed in the direction of the product drop filling cylinder 1 of the double bracket 10 to perform vertical adjustment. If the length of the linear contact portion between the heater 4 and the film pressure-bonding band leaf spring 6 is increased, the heating time can be increased substantially and proportionately, and the thickness and type of the bag film can be adjusted delicately. Heating can be performed to the corresponding welding temperature, and the pinching pressure can be increased delicately and proportionately, so that welding sealing can be performed satisfactorily. Also, when welding is excessively performed while the temperature of the vertical heater 4 is appropriate, fine adjustment movement is performed in a direction away from the product drop filling cylinder 1 of the double bracket 10 so that the vertical heater 4 and the film crimping band are moved. If the length of the linear contact portion of the leaf spring 6 is reduced, the heating time can be substantially finely and proportionately shortened, and the film is heated to a welding temperature delicately corresponding to the thickness and type of the bag film. Although the nip pressure is reduced, the rolling pressure of the film pressure-feeding feed roll 7 and the floating roller 8 does not fluctuate, so that the welding seal can be performed satisfactorily.

In the vertical bag making and filling machine of the present invention, the joining portion of the both sides of the bag film (and the sealing tape for the seam) may be formed by a vertical heater, a film holding plate, and an arcuately curved film crimping band. It is a configuration in which the leaf spring and the leaf spring are sandwiched in the same pinching state, and the separation distance from the product drop filling cylinder to the film clamping surface can be finely adjusted.
Even if the vertical heater leaves the contact with the film spring for film crimping, the film holding plate and the film spring for film crimping continue to hold the packaging film (and the sealing tape for the seam) in the same state as during operation and for film crimping. The flatness of the bowed top of the band spring is maintained as it is, so when packaging with an envelope-attached vertical seal is performed, the bag width is adjusted by adjusting the separation distance from the product drop filling cylinder to the film clamping surface. A slight adjustment is effective, the alignment of both edges of the bag film is not disturbed, and the packaging operation that avoids waste paper can be performed. By adjusting the separation distance from the product drop filling cylinder to the film holding surface, it is possible to realize a vertical seal that allows both edges of the bag film to be exactly abutted without gaps, and to align both edges of the bag film Minute is not disturbed, it is the packaging operation that can avoid the generation of waste paper.
