The present invention relates to a packaging device capable of filling an object to be packed into a bag from a part.

(Prior Art) Conventionally, in Japanese Patent Laid-Open No. 63-304803, as shown in FIG. 7, a bag (2) is formed by a vacuum suction force of a nozzle (3) having a hollow inside.
After being adsorbed by the nozzle (3) and carried into the inner wall (6), the porous portion is generated by the vacuum suction force acting on the hole (5) on the bottom surface of the double wall stand (1) supporting the inner wall (6). At the same time as making the inside of the inner wall (6) a negative pressure through (7), the nozzle (3)
Disclosed is a device for ejecting air (4) from the bag to inflate the bag (2) along the inner surface of the inner wall (6). According to the device, there are few opening mistakes in the bag (2), and at the same time, the objects to be packed in the bag (2) are evenly arranged in the inner width of the inner wall (6).

(Problems to be Solved by the Invention) However, in the above-mentioned device, not only the inner width of the inner wall is constant and it is not possible to cope with the variety of bags, but also the bag filled with the object to be packaged must be pulled out upwards, which is efficient There's a problem.

(Means for Solving the Problems) In order to eliminate the above-mentioned drawbacks, the present invention is designed such that after a bag covered with a porous hollow having a hollow interior is adsorbed to the porous hollow and is carried between opposing wall surfaces of a double structure facing each other. , The air pressure ejected from the porous porcelain into the bag and the vacuum suction force acting on the breathing hole formed in the opposing wall surface of the double structure to expand the bag toward the opposing wall surface of the double structure. In the device, the double opposing wall surfaces are free to be inserted into the tubular material (11) corresponding to the outer wall of the tubular material (11) from the upper surface opening portion of the tubular material and have a constant interval. And at least two inner walls (19) facing each other, a means for sealing the peripheral edge of the inner wall to the inner surface of the tubular material to form an airtight space between the tubular material and the inner wall, and an inner wall in the tubular material. The inner wall is made of a tubular material to restrain unnecessary downward freedom. Means for holding, means for applying a vacuum suction force to the suction hole (22) formed in the inner wall facing surface through the space between the cylindrical member and the inner wall, and regulation of downward movement of the bag between the inner walls. And a bottom plate (41) that rotates downward to eliminate the restriction on the bag.

In order to ensure the expansion of the bag, the bag covered with the porous hollow with a hollow inside is adsorbed to the porous shaft and carried into the space between the opposing wall surfaces of the double structure facing each other, and then the bag inside the bag. A device for inflating the bag toward the opposing wall surface of the double structure by the air pressure ejected to the air and the vacuum suction force acting on the breathing hole formed in the opposing wall surface of the double structure, The porous sword has a pair of clamps (33) for sandwiching the rim of the bag (A) on both sides of the swordboard, and a means for bringing these clamps into contact with and separate from the swordboard.

(Operation) After the bag covered with the porous hollow inside is adsorbed to the porous hollow and carried in between the opposing wall surfaces of the double structure facing each other,
Due to the air pressure ejected from the porous porcelain into the bag and the vacuum suction force acting on the breathing hole formed in the opposing wall surface of the double structure, the bag is inflated toward the opposing wall surface of the double structure. In the above device, the double opposing wall surface is
An inner wall (19) having at least two surfaces is configured to be freely inserted from an upper surface opening of a tubular material (11) corresponding to the outer wall. Since the peripheral edge of the inner wall is sealed to the tubular material and the means for restraining the downward freedom of the inner wall is provided, it is possible to exchange inner walls having different inner width intervals according to the variety of bags.

Further, the bag expanded between both inner walls and filled with the object to be packaged can be removed in the downward direction due to the generation of gravity by the rotation of the bottom plate (41) which normally regulates the downward movement of the bag.

Further, in the above-mentioned porous sword, since the mouth edge of the bag can be pressed against the sword board with a clamp to blow air, there is little air leakage from the bag opening, and the bag can be inflated between the two inner walls. .

(Embodiment) As shown in FIGS. 1 and 2, the chamber (10) has a rectangular tubular member (11) having upper and lower openings, and a bottom plate provided in the lower opening (12) of the tubular member. (13) and the arm (14) (14) fixed to the tubular member can be rotated along a circular orbit. The bottom plate (13) is openably and closably supported by the chamber via a hinge (15), and a pulley (16) provided at the end of the hinge rolls along a circular rail (17) to hold down the force of the rail (17). Therefore, the bottom plate (13) normally closes the lower end of the chamber. Also, a pair of inner walls (19) (1) are provided on the inner facing surfaces (18) (18) of the chamber.
9) is provided. As shown in FIG. 3, the inner wall has a flange (20) formed on the periphery, a flat convex portion (21) on the upper surface at the center, and a large number of suction holes (22) (2) on the convex portion.
2) are opened, and guides (23) (23) into which the flange (20) of the inner wall can be slid and inserted from above are provided on the chamber facing surface. Joint cups (24) (24) are fixed on the outside of the chamber facing surfaces (18) (18), and a vacuum line (25) is connected by hoses connected to these joint cups.
Ventilation holes (2
6) Through the (26), the vacuum line can bring the vacuum to the inside of both inner walls (19) (19) only when needed.

On the other hand, as shown in FIGS. 4 and 5, the plate-shaped whistle (30) has a hollow interior, and a large number of breathing holes (31) (31) are formed on both front and back surfaces of the whistle, and a hose is provided above the whistle. A pipe (32) for connection is provided, and a pair of clamps (33, 33) are provided on the pipe. The clamp has laterally long clamp plates (34) (34) at its lower end, and the clamp plates are pressed against both sides of the turret by springs (35) (35), and a lever ( 36) (36) can be operated by an air cylinder or an electromagnetic solenoid (37).

Then, when the bag (A) is put on the bamboo (30), the pipe (3
As a result of the vacuum (38) being introduced through the inside of the chest, the bag is sucked onto the surface of the chest by the vacuum suction force acting on the breathing holes (31) (31). After that, the bag (A) is inserted from above the chamber (10) together with the barn with the bar (39), the inside of the barn is turned into a vacuum, and the pressurized air (40) is blown into the bag (A). Since it is pressed against the shaft with clamps (33) from both sides, the bag is greatly inflated by the pressurized air blown, while the vacuum line (25) (2
The bag is adsorbed by the suction holes (22) (22) on the inner wall by the vacuum suction force acting on the inner wall via 5) and opened. After that, when the whistle is pulled out, the chamber rotates in a circular orbit and the bag (A) is filled with the object to be packaged at the next stop position, and the bottom plate (41) below the bag is subjected to a drop impact of the object to be packaged. I can endure it.

Then, as shown in Fig. 6, the lid (42) is placed on the upper part of the chamber.
Is airtightly covered, and a vacuum is introduced into the chamber through a hose (44) connected to a hole (43) on the side surface of the chamber in FIG. When the inside of the chamber reaches a vacuum, the pair of seal bars (45) (45) in FIG. 6 approach each other with the air cylinders (46) (46), and the lower bar (47) (47) closes the bag mouth. After heat-sealing while sandwiching, the atmosphere is introduced into the chamber. Eventually, the bottom plate (13) of the chamber is opened by bending the rail (17). As shown in Fig. 2, one side of the seat plate (41) has a pin (48).
The seat plate (41) is rotatably supported by the chamber via the (48), and the seat plate (41) is linked so as to interlock with the bottom plate (13) (not shown). The vacuum-packed product is discharged downward by opening to.

Since the article to be packaged is shaped according to the inner wall spacing (B) on both sides in FIG. 1, the thickness of the article to be packaged should be changed by replacing it with a convex portion (21) having a different height in FIG. It can be changed arbitrarily. From such a viewpoint, it is possible to change the thickness of the packaged object by fixing the inner wall on one side to the chamber and fixing only the inner wall on the other side. Further, by forming the inner wall (19) with a steel material and providing a permanent magnet on the outside of the chamber, it is possible to freely attach the inner walls having different heights to the chamber by its magnetic attraction force.

(Effect) The present invention can easily change the thickness of the object to be packaged in the bag, which adjusts the shape evenly to the inner wall width, by changing the inner wall,
Since the bottom plate that regulates the downward movement of the bag is rotated between the inner walls and the bagging package can be removed downward by gravity, the packaging efficiency is improved as compared with the conventional one in which the package is extracted upward.

In addition, since the perforated sardine that adsorbs the bag between the inner walls and carries it in is sealed by pressing the bag mouth to the sword plate with a clamp, the air blown out from the porous porcelain does not leak from the bag mouth and It is possible to surely inflate between the inner walls and further reduce mistakes in opening the bag.
