If a chlorine-based disinfectant or the like is hermetically sealed in the packaging bag, carbon dioxide gas, chlorine gas, etc. are generated from these contents, which causes inconvenience such as expansion of the packaging bag. For this reason, a ventilation hole is formed in the packaging bag, a vent valve is adhered to the packaging bag so as to cover the ventilation hole, and the degassing packaging bag is filled with coffee beans or the like, whereby the inside of the packaging bag is filled. The gas generated at the time is escaping to the outside through the vent valve (JP-A-56-32239, JP-A-56-32244, and JP-A-60-32244).
No. 57069).

In FIG. 5, a is a base plate, b is a valve storage roller, c
Is a valve holding belt, d is a degassing valve, e is a take-up roller, f is a support, g is a pivot point, h, h ', h "are cylinders, i, i', i"
Is a piston rod, j is a needle, k is a pressing plunger, 1 is a mandrel, m is a notch, and n is a packaging bag. When the degassing valve d is attached to the packaging bag n by the above-described device, the cylinder i 'is advanced to a predetermined position of the packaging bag n in which the mandrel 1 is inserted, and a vent hole is formed by the needle j. The support f is rotated by the operation of i ″, the valve d on the holding belt c is attached to the tip end surface of the plunger k by the pressing plunger k, and is transferred above the ventilation hole, and the cylinder i is advanced. The lever valve d is pressed against the packaging bag n and attached.

3aを元の位置に復帰させる。When attaching the gas release valve to the packaging bag filled with the contents by the above-described device, the conveyor 1 is intermittently moved, and when the packaging bag 3 reaches the position A of the ventilation hole forming device, the vacuum suction device 6 is first turned on. The suction device 6 is lowered to bring the distal end surface of the suction device 6 into contact with a predetermined location on the outer surface of the packaging bag 3 and to operate the vacuum pump 12 to vacuum-evacuate the inside of the ring-shaped groove 9 to reduce the pressure. The outer surface of the packaging bag 3 is adsorbed to the surface. Next, as shown in FIG. 4, the suction device 6 is used to prevent the contents 26 of the packaging bag 3 from being damaged by the blade 13.
Is slightly raised to form a gap 27 between the packaging material 3a and the contents 2, then the blade body 13 is lowered, and the cutting edge 13a is pierced into the packaging material 3a, thereby forming one or more wires on the packaging material 3a. A ventilation hole 28 having a shape such as a semicircle is formed. Then, after forming the ventilation holes 28, the blade body 13 is lifted to remove the blade edge 13a from the packaging material 3a, and the vacuum pump 12 is opened to release the reduced pressure state in the groove 9 to thereby wrap the blade from the tip end surface of the suction device 6. Release material 3a, packaging material

When forming 28, the packing material 3a is formed by the ring-shaped groove 9 of the suction device 6.
The packaging material 3a is stretched inside the groove 9 and the ventilation hole 28 is formed in this part of the packaging material 3a by the blade body 13.
Unlike the conventional apparatus shown in FIG. 5, it is not necessary to insert a mold inside the packaging bag to stretch the packaging material.
The air holes 28 can be formed while the contents 26 are still filled therein. Further, the packaging material 3a is lifted while being stretched inside the groove 9, and the packaging material 3a is separated from the content item 26 before the ventilation hole 28 is formed.
26 is not damaged, and the packaging material 3a is in a tensioned state inside the groove 9, so that the displacement of the vent hole 28 does not occur.

装置。1. A valve mounting apparatus comprising: a vent forming unit for forming a vent in a packaging bag; and a valve attaching unit for attaching a gas release valve to the packaging bag covering the vent. The vent hole forming device section is provided with a ring-shaped groove on the distal end surface of a cylindrical vacuum suction device provided so as to be able to advance and retreat, and connects the ring-shaped groove with a vacuum generating device; A blade for forming a ventilation hole is arranged so as to be able to advance and retreat inside,
The operation of the vacuum generating device causes the inside of the ring-shaped groove to be in a vacuum or reduced pressure state, so that a predetermined portion of the outer surface of the packaging bag is suctioned to the tip end surface of the vacuum suction device, and the above-described communication is performed in a state where the vacuum suction device is retracted. An apparatus for mounting a gas release valve, characterized in that the air hole forming blade body is advanced and an air hole is formed on the outer surface of the packaging bag with the blade body.
