A pair of drive sources 113 respectively turn the pair of support shafts 107 in the direction of arrow α. Thereby, the flap 33 welded to the side edge 35 of the bag body 19 in the manufacturing process of the bag body 19 can be immediately separated from the bag body 19.

  Since the drive source 113 turns the cutter 111 to the position represented by the imaginary line 111 ′ in the direction of the arrow α, the cutter 111 traverses the side edge 35 of the bag body 19 outwardly, and opens the bag body 19. The part 127 and the flap 33 are separated from each other. Further, when the cutter 111 rotates as described above, the gap where the cutter 111 enters is positively opened between the opening 127 of the bag 19 and the flap 33 by the injection of the flap blowing means 129. May be.

  On the other hand, the flap holding means 11 opens between the fixed piece 79 and the outer movable piece 97. As shown in FIG. 7, the rotating machine 133 of the push-up means 137 turns the turning arm 139 in the direction of the arrow β. In this process, the push-up member 131 moves along a circular arc centered on the output shaft 135 and comes into contact with the flap 33 of the bag body 19 from below. As a result, the flap 33 bends above the opening 127 as indicated by the virtual line 33 ′, so that the flap holding means 11 enters between the fixed piece 79 and the outer movable piece 97. The flap holding means 11 closes between the fixed piece 79 and the inner movable piece 87, and holds the flap 33 of the bag body 19 above the opening 127. In this step, the cylindrical member 73 and the outer movable piece 97 are in a position where they block the stroke of the push-up member 131, but the swing arm 143 turns against the torsion spring and the like to move the push-up member 131 to the arrow β You can escape in the opposite direction.

  C: The transfer means 67 rotates the turn plate 69 by 60 ° in the direction of the arrow θ. The input means 13 inputs one or a plurality of articles 23 supplied by the supply device into one bag body 19.

  D: The transfer means 67 rotates the turn plate 69 by 60 ° in the direction of the arrow θ. As shown in FIG. 10, the clamping means 151 opens a pair of clamping pieces 147 and stops the drive source 149. In this state, it is preferable that the liner blowing means 179 injects airflow onto the liner 177 of the bag body 19 to positively lift the liner 177 from the blank space where the adhesive portion of the flap 33 is not formed.

  Subsequently, the sandwiching means 151 can quickly peel the liner 177 from the flap 33 of the bag body 19 without manual intervention. That is, the sandwiching means 151 closes the pair of sandwiching pieces 147 so that the liner 177 lifted from the flap 33 is sandwiched therebetween. The rotating machine 155 turns the clamping means 151 together with the turning arm 153 around the output shaft 157 in the direction of the arrow γ. As a result, the pair of sandwiching pieces retracts from the bag body 19, and the liner 177 sandwiched between the pair of sandwiching pieces 147 is transferred directly above the rotating machine 155. In this state, the clamping means 151 reopens the pair of clamping pieces 147 and releases the liner 177. The liner 177 is sucked into the escape passage 169 of the discharge means 159 and discharged to another place through a hose connected to the other end 175. For this reason, the operation | work of removing the liner 177 from between a pair of clamping pieces 147 is unnecessary.

  E: The transfer means 67 rotates the turn plate 69 by 60 ° in the direction of the arrow θ. The flap holding means 11 opens between the fixed piece 79 and the outer movable piece 97 to release the flap 33. As shown in FIG. 12, the rotating machine 189 of the pressing means 193 turns the turning arm 187 in the direction of the arrow δ. In this process, the pressing member 183 and the close contact member 185 move along a circular arc centered on the output shaft 191 and sequentially contact the flap 33 of the bag body 19 from above to open the flap 33. The folded bag body 19 can be quickly closed to the portion 127 without manual intervention. In this step, the cylindrical member 73 and the outer movable piece 97 are in a position where the stroke of the pressing member 183 is blocked, but the swing arm 197 rotates against the torsion spring or the like, and the pressing member 183 is moved to the arrow δ. You can escape in the opposite direction.

  Moreover, the close contact member 185 is elastically deformed following the shape of the bag body 19 when coming into contact with the flap 33 of the bag body 19 from above, so that the thick article 23 is inserted into the bag body 19. Even if the opening 127 of the bag 19 is deformed into strain, the flap 33 can be brought into close contact with such an opening 127 to prevent wrinkles from occurring in the flap 33.

  F: The transfer means 67 rotates the turn plate 69 by 60 ° in the direction of the arrow θ. The header holding means 5 opens between the fixed piece 79 and the inner movable piece 87 to release the header 31. As a result, the bag body 19 drops from the header holding means 5 to the carry-out means 27 and is carried out of the housing 37 by the carry-out means 27. The article bagging apparatus 1 can perform the series of steps described so far without human intervention.

  It should be noted that the present invention can be carried out in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. In the embodiment, the operation of the article bagging apparatus 1 has been described by paying attention to one bag body 19, but the process A is performed every time the carrying-in means 21 carries the bag body 19 into the article bagging apparatus 1, The steps A to F proceed simultaneously with the six bag bodies 19 sequentially carried into the article bagging apparatus 1 by the carry-in means 21 as targets.

  Further, the transfer unit 67 may be omitted, and the cutting unit 7, the bag opening unit 9, the throwing unit 13, and the peeling unit 15 may be sequentially moved to a position facing the front surface of the bag body 19. The number of the header holding means 5 is not limited, and the present invention can be implemented by attaching one or more header holding means 5 to the turn plate 69. This also applies to the flap holding means 11. The above-described drive source, rotating machine, air cylinder, and the like can be replaced with any drive source such as an electric motor or a hydraulic cylinder.
