[0004]

[Operation and Effect] The sandwich A is sandwiched by the sandwich transport device (1), and the packaging bag (1) is transported by the packaging bag transport device (2).
00) are conveyed toward the sandwich projecting station S while intermittently moving. The packaging bag (100) reaching the sandwich ejection station S is opened with an opening device.
The lower surface of the packaging bag (100) is suction-held by the suction surface (41) of (4). The suction nozzle (46) descends, sucks the upper surface of the opening edge of the packaging bag (100), and rises. This allows the packaging bag (1
The mouth of (00) opens.

At the same time as the above operation, the sandwich A on the sandwich conveying device (1) is protruded from the sandwich and stopped at the station S, and the protruding device (3) is operated to open the mouth and wait for the package. The sandwich A is inserted into the bag (100). The pushing stroke of the pushing device (3) is long enough to allow the sandwich A to be pushed into the sandwich accommodating portion (61) of the turntable (6) in front of the standby position of the packaging bag (100). is there.

When the push-in operation of the push-in device (3) starts, the turntable (6) has stopped one sandwich accommodating portion (61) in correspondence with the sandwich ejection station (S). By the pushing operation of the pushing device (3), the sandwich A is pushed into the packaging bag (100) and is pushed into the sandwich accommodating portion (61) of the turntable (6) as it is.

Next, the first folding claws (72) are raised, and the packaging bag is opened.
The lower part of the opening edge of (100) is folded upward (FIG. 8). The second folding claws (73) slide to fold the side of the opening edge of the packaging bag (100) toward the rotating side of the turntable (6) (FIG. 9). The turntable (6) rotates one pitch in synchronization with the timing at which the first folding claw (72) descends, and the remaining side of the opening edge of the packaging bag (100) hits the third folding claw (74) to turn the turntable (74). 6)
(FIG. 10). The second folding claw (73) retreats to the original position. When the turntable (6) stops, the fourth folding claw (71) descends and folds the upper part of the opening edge of the packaging bag (100) downward (FIG. 11). The fourth folding claw (71) rises to the original position while the turntable (6) rotates again by one pitch, and when the turntable (6) stops, the joining device is turned on.
(9) operates to attach a label over the last folded portion and its periphery, or to join the folded portions by heat welding. The above operation is repeated every time the sandwich A is moved by one pitch by the sandwich transport device (1), so that the sandwich A can be efficiently and sanitarily packed without touching the sandwich A during the packaging operation.

Description of the operation of the above packaging device The sandwich A is sandwiched by the sandwich conveying device (1).
The packaging bag (100) is transported toward the sandwiching and projecting station S while intermittently moving by the packaging bag transport device (2). The lower surface of the packaging bag (100) that has reached the sandwich ejection station S is suction-held by the suction surface (41) of the opening device (4). The suction nozzle (46) descends, sucks the upper surface of the opening edge of the packaging bag (100), and rises. This opens the mouth of the packaging bag (100). Match the above operation and timing
(1) The sandwich A above stops at the sandwich ejection station S, the pushing device (3) is operated, and the sandwich A is opened and the sandwich A is placed on the waiting packaging bag (100).
Thrust. When the push-in operation of the push-in device (3) is started, the turntable (6) is placed in the sandwich housing (6).
1) is stopped in correspondence with the sandwich projecting station S. By the pushing operation of the pushing device (3),
The sandwich A is pushed into the packaging bag (100), and is further pushed into the sandwich accommodating portion (61) of the turntable (6) through the entrance (67) of the wall plate (66) surrounding the turntable (6). It is.

Next, the first folding claws (72) are raised, and the packaging bag is opened.
The lower part of the opening edge of (100) is folded upward (FIG. 8). The second folding claws (73) slide to fold the side of the opening edge of the packaging bag (100) toward the rotating side of the turntable (6) (FIG. 10). When the turntable (6) rotates, the remaining side of the opening edge of the packaging bag (100) hits the third folding claw (74) and turns the turntable (74).
It is folded to the anti-rotation side of (6) (FIG. 10). When the sandwich A on the turntable (6) stops corresponding to the next station S1 due to the operation of the turntable, the fourth
The folding claws (71) descend to fold the upper part of the opening edge of the packaging bag (100) downward (FIG. 11). When the turntable (6) rotates again and stops at the next station S2, the joining device
(9) is activated to apply a label near the tip of the last folded piece of the packaging bag (100). When the sandwich accommodating portion (61) of the turntable (6) accommodating the sandwich A stops at the ejection station S3, the ejection piece (82) of the discharging device (8) descends, and the packed sandwich is removed from the bottom plate.
It is ejected downward from the opening (65) of (64). The above operation is repeated every time the sandwich A is moved by one pitch by the sandwich transport device (1), so that the sandwich A can be efficiently and hygienically packed.

As in the above embodiment, the lower surface of the packaging bag (100) is sucked and held at the sandwich projecting station S, and the upper part of the opening is sucked and lifted by the suction nozzle (46) to lift the packaging bag (100). When opening the mouth, if the suction nozzle (46) is raised while the turntable (6) is moving, the packaging bag (100)
Of the sandwich A can be smoothly lifted.

In carrying out the present invention, the joining device (9) is not limited to a labeling device, but may be a device for thermally welding folded pieces of the packaging bag (100).

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
