Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hygroscopic agent, a deodorant, a deaerator for adsorbing and fixing oxygen, carbon dioxide, and the like, and an antiseptic for releasing alcohol on the inner surface of a packaging bag. The present invention relates to a vertical bag-making filling and packaging method for accommodating a flat pouch containing an agent or a non-product object such as a premier film in an adhesive state.

[Prior Art] Conventionally, in a vertical bag-making filling and packaging machine, a flat and breathable pouch containing non-product objects such as a dehumidifying agent, a deodorant, and a premier film is generally stored in each packaging bag. A typical method is a method in which one of the sachets is addressed and dropped from the product dropping cylinder inside the former in accordance with the timing of dropping and filling the packaged object. This method is called method a.

Furthermore, when bagging coffee powder that has just been roasted in a vertical bag-filling and packaging machine, flat air-permeable sachets containing degassing agents that adsorb and fix oxygen, carbon dioxide, etc. As shown in FIG. 6, the pouches H are connected to each other with a thermoplastic film tape r at a predetermined interval so as to have a pitch matching the length of the packaging bag.
This is passed through the inside front of the product dropping cylinder so that the pouch is located in the middle of the packaging bag as shown in FIG.
There is a packaging method for laterally sealing the packaged product S. This method is called method b.

In addition, when bagging freshly roasted coffee powder, instead of containing a small bag containing a degassing agent that adsorbs and fixes oxygen and carbon dioxide, a gas vent valve is attached to generate coffee powder. Carbon dioxide is discharged outside the bag. The gas vent valve is a check valve so that coffee powder is not oxidized. Then, the gas vent valve is attached to the outer surface of the bag by heat bonding on the rear surface of the product dropping cylinder.

[Problems to be Solved by the Invention] According to the above-mentioned method a, there is a risk that dehumidifying agents, deodorizing agents, etc. may be mixed into food or erroneous eating. Further, when the flat pouch containing the premium film is accommodated in the packaging bag by the above method a, there is a problem that the packaging speed cannot be increased because there is a difference in the falling speed of the pouch and the object to be packaged. .

Further, the above method b can be practically used when the packaging film is plain and the horizontal sealing is performed according to the pitch of the pouch, but when the printed packaging film is used and the horizontal sealing is performed according to the registration mark, It is unavoidable that the position of the pouch within the pouch gradually shifts and the lateral heater bites the pouch, which is not practical.

Furthermore, in the above method c, it is completely ineffective to attach a flat pouch containing a dehumidifying agent, a deodorant or the like to the outer surface of the packaging bag in place of the gas direction valve. The gas direction valve and pouch cannot be replaced.

The present invention has been devised in view of the above-mentioned points, and a hygroscopic agent, a deodorant, a degassing agent that adsorbs and fixes oxygen, carbon dioxide, or the like,
Alternatively, a flat small bag containing a non-product object such as a premier film should be stored in an adhesive state on the back surface of the packaging bag so that the package can be seen from the transparent part on the front of the bag without the small bag interfering with the bag. A vertical bag-making filling and packaging method that can ensure the good horizontal sealing without fear of the small bag being bitten by the horizontal sealer when the horizontal sealing is performed and can increase the packaging speed. It is intended to be provided.

[Means for Solving the Problems] According to the present invention, as a means for solving the above problems, a continuous strip-shaped packaging film F fed from a raw roll is used.
The film is bent so as to wrap the product drop tube 2 passed through the inside of the former 1 and flows toward the V-shaped collar 1a on the front side of the former 1 in the vertical direction. It is passed through the slit slit 3 and held in the front side of the product dropping cylinder 2 and vertically sealed by a vertical sealer 4 to hang down as a packaging cylinder T below the product dropping cylinder 2 and is dropped and supplied through the product dropping cylinder 2 to fill the packaging cylinder T. In a vertical bag-making filling and packaging method in which the upper and lower positions of the packaged object are horizontally sealed by a horizontal sealer 5, a small bag swivel in which a slit upper part faces a front V-shaped collar a of the former 1 and has a required large opening A slit 6 serving as a mouth 6a is opened from the required upper part of the product dropping cylinder 2 to a lower end thereof, and a continuous strip-shaped packaging film F fed from the original roll is wound on the former 1 before being wrapped. A flat pouch H containing a non-product object adhered by a suitable method at a position near the edge of F and outside the position where the lateral sealing is performed is inserted into the product drop tube 2 through the pouch swallowing opening 6a. The present invention provides a vertical bag-making filling and packaging method characterized by the above. Therefore, the pouch H flows into the front V-shaped collar 1a through the shoulder portion of the former 1 and flows downward through the pouch swallowing opening 6a. When the lateral seal is made, the pouch H is bonded to the rear surface of the pouch. As a result, there is no risk that the pouch H will be bitten by the horizontal sealer 5, and it is ensured that good lateral sealing is performed, and high-speed operation becomes possible.

[Embodiment] A vertical bag-making filling and packaging method according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

First, in the vertical bag-making filling and packaging method according to this embodiment, a continuous strip-shaped packaging film F is installed behind the former 1 by a paper feed device (not shown) installed behind the former 1. It is fed from the original roll and guided to the rear of the former 1, and is guided between the former 1 and the product dropping cylinder 2 in a tubular shape so as to be wound around the product dropping cylinder 2 inside the former 1, and the film both edges f , f through the vertical slits 3 on the front side of the former 1 to guide them outward to form a palm shape, and the product dropping cylinder 2 below the former 1
The front side of the product is vertically sealed by the vertical sealer 4 to form the packaging cylinder T, and the paper drawing belts 7, 7 are provided on both sides of the product dropping cylinder 2.
Basically, the paper is pulled by the horizontal sealer 5 so that the vertical position of the object w to be packed in the packaging cylinder T below the product drop cylinder 2 is flattened by the horizontal sealer 5 so that the front and rear surfaces of the apparatus are flat. It has a simple structure.

The embodiment provides a vertical bag-making filling and packaging method for packaging coffee powder, in which an auger 9 is passed through the inside of the hopper 8 and the product dropping cylinder 2 and the screw rotation of the auger 9 causes an accurate fixed amount. The coffee powder (object to be packaged) w is extruded from the lower end of the auger, and is filled in the packaging cylinder T that is delivered below the product dropping cylinder 2.

And in this example, the roasted coffee powder is
Considering that it releases a large amount of carbon dioxide and is easily oxidized by oxygen in the air, each packaging bag is mixed with a deoxidizer that adsorbs and fixes oxygen and a decarbonate that adsorbs and fixes carbon dioxide. Flat pouch H with breathability
On the rear side of the former 1 via a double-sided adhesive tape so as to adhere to the rear surface of the bag.

The pouch H is adhered to the packaging film F on the upper surface of the packaging film F which flows behind the former 1 toward the former 1 horizontally or with a slight inclination. Since the upper surface of the packaging film F is folded back at the former 1 to form the inner surface of the bag, the upper surface of the packaging film F is covered with the pouch H.
Is adhered, the pouch H is adhered to the inner surface of the bag.

According to this embodiment, the pouches H are continuous ones without being cut at the time of horizontal sealing, which are packaged by a vertical bag filling and packaging machine (not shown) capable of flat three-way packaging or four-way packaging, and are arranged above the device. Double-sided adhesive tape sticking machine installed
It is introduced from below into 10 and is passed through the guide rolls 10a and 10b to convert the direction downward, and further passed through the guide rolls 10c and 10d between the pair of double-sided adhesive tape attaching 10e, 10e, where the pouch H The double-sided adhesive tape p, which is separately guided to one side, is attached (FIG. 3), and then the cutter 10f cuts each bag according to the packaging cycle, and the upper surface of the packaging film F flowing toward the former 1. Drop it on. In this case, as shown in FIG. 4, the drop position of the pouch H is such that it slightly overlaps the film edge f on which the longitudinal sealing of the packaging film F is performed and the intermediate position between the registration mark m and the registration mark m. Then, the pouch rolls 1 for adhering the pouch rolls 1 attached to the packaging film F are attached to the packaging film F at upper and lower positions.
The double-sided pressure-sensitive adhesive tape p adhered to one surface of the pouch H is adhered to the packaging film F by passing between 1 and 11.

In the double-sided pressure-sensitive adhesive tape sticking machine 10, the double-sided pressure-sensitive adhesive tape p is used by being adhered to a mount and wound in a roll, and the pair of double-sided pressure-sensitive adhesives is attached to the continuous pouch H from the upstream side of the packaging film F. Lead between 10e and 10e for tape application,
The tape mount p'is peeled off and adhered to the pouch H, and the tape mount p'is wound up. By doing so, when the pouch H cut by adhering the double-sided adhesive tape p is regulated by the falling guide 10g and falls on the packaging film F and falls, the double-sided adhesive tape p is placed below the pouch H. And can adhere to the packaging film F.

The pouch H adhered to the edge f of the wrapping film F in this manner flows through the shoulder of the former 1, flows into the V-shaped collar 1a on the front side, and flips inward. However, since the gap between the former 1 and the product dropping cylinder 2 is only about 3 to 4 mm, in the present invention, the slit 6 is opened from the required upper part of the front part of the product dropping cylinder 2 to the lower end, and the slit 6 is formed. The pouch swallowing opening 6a exposed above the V-shaped collar 1a swallows the pouch H. In addition, the large gap between the product drop tube 2 and the auger 9 ensures that the pouch H is prevented from entering the inside of the former 1. The pouch H flipped over to the inside of the former 1 is located inside the packaging tube T,
Since one end is adhered to the film edge f of the packaging film F, the longitudinal slit 3 on the front side of the former 1 is formed.
As shown in FIG. 5, when it reaches a position corresponding to the vertical sealer 4, the vertical sealer 4 sandwiches a few mm width of the end of the pouch H and firmly bonds it to the vertical seal portion. Does not result in poor sealing.

In this way, the pouch H strongly adhered to the vertical seal position at the center of the rear surface of the bag near the registration mark m of the packaging film F is
The ejection force of the coffee powder w supplied from the auger 9 prevents the adhesive from peeling off, and the adhesive is buried in the coffee powder w, so that the horizontal sealer 5 does not bite the pouch H and performs a good horizontal seal. be able to.

The vertical bag-making filling and packaging method of the present invention is a hygroscopic agent, deodorant, degassing agent for adsorbing and fixing oxygen, carbon dioxide, or the like, or a flat pouch containing a non-product object such as a premier film, It can be widely used as a technique for accommodating the inner surface of a packaging bag in an adhesive state, and can also be applied to a case where a packaged object is directly loaded from the hopper 8 without using the auger 9. Furthermore, the adhesion of the pouch H to the packaging film F is
When the pouch is manufactured in advance, a thermoplastic film is attached to one side of the pouch H, and the pouch rolls 11 and 11 for adhering the pouches in FIG. 1 are used as heater rolls.
The thermoplastic film attached to the pouch H by 11 may be heat-welded to the edge f of the packaging film F.

[Effects of the Invention] As described above, according to the vertical bag-making filling and packaging method of the present invention, the flat pouch containing the moisture absorbent and the deodorant is placed at the horizontal sealing position of the packaging film behind the former. Since it is configured to adhere to the end of the product drop barrel and to form a slit on the front side of the product drop barrel from above the V-shaped collar of the former to the lower end of the product drop barrel, the pouch passes through the shoulder of the former. It flows to the V-shaped collar on the front side, is turned over to the inside of the pouch from the upper part of the slit formed in the product dropping cylinder, flows downwards inside the packaging tube T, and on the rear surface of the bag when a horizontal seal is made. As a result of being bonded, there is no risk of the pouch being bitten by the lateral sealer, and it is guaranteed that a good lateral seal is performed. Then, the flat pouch can be adhered to the packaging film at a high speed, so that the packaging speed can be increased.

Therefore, according to the vertical bag-making filling and packaging method of the present invention, a flat pouch containing a hygroscopic agent, a deodorant, a deaerator that adsorbs and fixes oxygen, carbon dioxide, or the like, or a non-product object such as a premier film. Since it can be packaged by being housed in an adhesive state on the back surface of the packaging bag, there is no risk of dehumidifying agents, deodorants, etc. being mixed with food and accidental ingestion, and the objects to be packaged in the bag can be packaged. When looking through the transparent part on the front, the pouch can be seen without obstruction.
