After the confirmation, the first gripper 60 is lifted to lift the container.
The servo motor that raises the first gripper 60 detects a change in pitch due to a change in load applied when lifting, determines the type of container, and determines the lifting height. As a result, in the present embodiment, it is determined that the bottle is one of the one bottle and the four bottles, and the bottle can be lifted at least to a height where the bottom surface of the bottle exceeds the upper edge of the case.
The transfer step 64 is a step of transferring the container lifted by the first gripper 60 from the first predetermined position 22 to the first packaging position 50. During the transfer process 64, the spacing of the three first grippers 60 is also widened according to the spacing of the packaging bags arranged in the first packaging position 50 in the bag opening unit 72. Thereby, when the container is transferred from the first predetermined position 22 to the first packaging position 50, the container is arranged immediately above the packaging bag.
The descending step 65 is a step in which the first gripper 60 descends to insert the container into the packaging bag. In the present embodiment, one container or four bottles are inserted into a vertically long cosmetic bag. When the servo motor lowers the first gripper 60, it lowers the container by the height of the lift. As a result, the container individually packaged in the packaging bag is self-supporting on the first package delivery path 85 forming the first packaging position 50, at which time the first gripper 60 releases the container. Further, in the descending step 65, the guide 61 descends prior to the descending of the first gripper 60 in conjunction with the descending of the first gripper 60, and the lower end of the funnel-shaped guide 61 is inserted into the opening of the packaging bag. To be done. As a result, the container can be smoothly guided to the packaging bag.
After the lowering step 65, the first gripper 60 moves up and moves to the first predetermined position 22 to take out the next container. The above steps are repeated until the case is empty. When the case is empty, the empty case is unloaded in the empty case unloading step (6).

When the first packaging means 16 (4) bag supply process first insertion means 51 is operating, the first bag supply means 52 in conjunction with the first insertion means 51 is operated. Further, when the second inserting means 56 is operating in the second packaging means 17, the second bag supplying means 57 is operated in conjunction with the second inserting means 56. Since the bag supply process performed by the first bag supply means 52 and the second bag supply means 57 is the same process, the first bag supply means 52 will be described below.
The bag supply step is a step of supplying the packaging bags accommodated in the magazine 73 set in the bag stocker 70 to the first packaging position 50.
A packaging bag bundle consisting of a plurality of packaging bags is housed in the magazine 73 with the opening facing the predetermined direction. The magazine 73 is set on the magazine support unit 74 of the bag stocker 70. The magazine support unit 74 formed so as to be able to move up and down pushes up the remaining packaging bags every time the packaging bags are taken out by the bag taking-out unit 71. Thereby, the bag take-out unit 71 can always take out the packaging bag from the same height. The packaging bag adsorbed by the bag adsorbing mechanism 75a of the bag take-out unit 71 is unfolded and placed on the turning plate 75, and is held by the holding plate. As a result, the folds can be stretched and the packaging bag can be prevented from rising due to the crease. The vicinity of the mouth of the packaging bag on the turning plate 75 is gripped by the delivery claw 76, and is caused by the rotation of the bracket 80. The transfer claw 76 is gripped by the transfer claw 77 when the packaging bag is raised. The slider 82 provided with the transfer claw 77 laterally transfers the packaging bag along the rail 81 from the raising position of the packaging bag to the first packaging position 50. With the movement of the slider 82, three packaging bags are hung at the first packaging position 50 at predetermined intervals. When each packaging bag is arranged at a predetermined position in the first packaging position 50, the opening claw 78 provided so as to intersect with the delivery claw 76 grips the vicinity of the mouth of the packaging bag. Then, the delivery claw 76 releases the packaging bag, and the opening auxiliary claw 79 holds the packaging bag in place of the delivery claw 76. The opening assisting claws 79 fix the packaging bag along the lateral direction, and the opening claws 78 move in the front-rear direction to open the mouth of the packaging bag. The lower end of the funnel-shaped guide 61 is inserted into this opened gap, and the above container insertion step is performed. Then, the opening claw 78 and the opening auxiliary claw 79 release the packaging bag in conjunction with the end of the container inserting step. As a result, the individual packaging of the container is completed, and the individual packaging product is formed. The formed individual packaged product is unloaded in the individual packaged product unloading step.

(5) Individual Packaged Product Unloading Step The individual packaged product unloading step is a step of unloading the individual packaged products in which the containers are individually packaged in the packaging bags from the first packaging position 50 to the packaged product stocker 86.
The first packaging position 50 is formed at one end of the first package delivery path 85 of the first package delivery means 53. A first package stocker 86 is connected to the other end of the first package carry-out path 85. Similarly, the second package delivery means 58 has a second package delivery path 89 having the second packaging position 55 at one end, and the second package stocker 90 at the other end of the second package delivery path 89. Are connected. Hereinafter, the first package delivery device 53 side will be described.
The first package delivery path 85 stops the conveyor while the first inserting unit 51 performs the container unloading/inserting step of inserting the container into the packaging bag at the first packaging position 50. As a result, the container can be inserted into the packaging bag while being stabilized. When the container is inserted into the packaging bag and the opening claw 78 and the opening auxiliary claw 79 release the packaging bag, the conveyor of the first package delivery path 85 operates to carry out the individual package. When the passage of the individual packaged goods is detected by the sensor provided on the first packaged goods carry-out path 85 and it is confirmed that the individual packaged goods have been carried out from the first packaging position 50, the conveyor is stopped and the next A container removal/insertion process is performed. The individually packaged products thus packaged one after another move through the first package carry-out path 85 and are sent to the first package stocker 86. The first package stocker 86 comprises a turn conveyor 88 having a table 87, and the turn conveyor 88 rotates in synchronization with the conveyor of the first package carry-out path 85. As a result, the individual packaged goods are delivered from the first packaged goods carry-out path 85 to the table 87. Individually packaged items stored on the table 87 are taken out by an operator, and a shipping operation such as binding the bag mouths or hanging a booklet is performed.
