Further, the suction pads 10a and 10b
Constitute a part of the bag opening device 5. That is, as described above, the bag 7 is adsorbed and transferred to the bag opening device 5, the opening seal device 6 and the carry-out conveyor 11, and at the same time,
The two lower suction pads 12 and 12 from the lower position of the two suction pads 10a and 10b on the side of the supply conveyor 2, that is, from the lower position facing each other with the bag 7 in between are the cylinder 2
9 rises and is adsorbed to the lower surface of the opening of the bag 7 to fix the lower surface of the opening.

Next, after confirming the suction of the lower suction pads 12, 12, the suction pads 10a and 10b are raised to a predetermined height, and the opening of the bag 7 is opened by the suction pads 10a and 10b.

In the figure, 13a and 13b are seal bars constituting the opening seal device 6 of the bag 7, which are opposed to the suction pads 10a and 10b and the lower suction pad 12 slightly forward and downward. The suction pads 10 a and 1 are provided by detecting that the cup-shaped product 1 is filled in the bag 7.
0b and the lower suction pad 12 close the opening of the bag 7, and the bag is advanced by a cylinder or the like (not shown), and the opening is sandwiched and heat-bonded.

In the figure, 27 is a folding plate which advances from both sides of the opening of the bag 7 to the folds in the center of the bag when the opening is sealed and enables accurate folding and heat bonding. is there.

Further, in the present invention, the opening of the bag 7 is detected between the bag opening device 5 and the opening seal device 6 and the supply conveyor 2, and the bag 7 is advanced to the front so that the front end is installed in the bag opening. A guide portion 14 having a tapered conical shape, which is inserted and at the same time the tip is expanded, is provided. The details are shown in FIGS. 3 and 4.

That is, the whole is formed into a tapered conical shape and the tip is widened, and moreover, in order to maintain the inside of the cup-shaped product 1 in a circular shape, the tapered conical portion has a large number of parts. It is divided into strips 14a, 14a ....

Each of the strips 14a, 14a ... Has two discs each having a hole punched out at the center, specifically, a first donut shape vertically arranged with an appropriate interval. The disk 15 and the second donut-shaped disk 16 are supported, and the tip of the disk is expanded.

That is, each of the strips 14a, 14a ...
The outer side on the base side of is supported movably in the outer direction by the pin 17 on the inner peripheral portion of the central hole of the first doughnut-shaped disc 15, and the outer side in the tip direction is the pin 1.
9, the link 18 and the pin 20 are movably supported in the outer peripheral direction on the inner peripheral portion of the central hole of the second donut-shaped disc 16.

Further, a piston rod 21a of a cylinder 21 provided on the first donut-shaped disc 15 is connected to the second donut-shaped disc 16 and the cylinder 21 forms a second donut-shaped disc. The plate 16 is replaced with the first donut-shaped disc 15
It is constructed so that it can be drawn to the side.

That is, when the second donut-shaped disc 16 is pulled toward the first donut-shaped disc 15 side by the cylinder 21, the strips 14a, 14a, ...
・ The tip direction of each is lifted outward and the tip is expanded.

Further, in the present invention, the first donut-shaped disc 15, the second donut-shaped disc 16, and the strips 1 of each.
A guide portion composed of 4a, 14a, ..., A link 18 and a cylinder 21 are integrally movable and returnable by a cylinder 22 supported on the frame side.

Specifically, the piston rod 22a of the cylinder 22 fixed to the frame 23 is connected to the first donut-shaped disc 15.

With the above construction, the cylinder 22 is actuated to move the entire guide portion 14 forward, and the tip of the guide portion 14 is inserted into the opening of the bag 7. At the same time, the cylinder 21 is actuated to expand the tip. Keep the opening of the bag 7 in a substantially circular shape,
The bagging operation of the cup-shaped product 1 by the pusher-4 described below can be completed.

Next, above the supply conveyor 2, the cup-shaped product 1 is lowered to the rear of the cup-shaped product 1 on the supply conveyor 2 to press the cup-shaped product 1 to fill the inside of the bag 7 from the guide portion 14. A pusher -4 is provided which returns by the operation.

The pusher-4 has a length such that it can be lowered between the cup-shaped products 1 placed on the upper surface of the supply conveyor 2 with an appropriate interval.
It is configured to be positioned on both sides of the locking portion 3 and to be able to press the rear portion of the cup-shaped product 1.

The pusher 4 is moved up and down by a cylinder 24 supporting the pusher 4, and the cylinder 24 is screwed to advance and return.
The cylinder 24 supporting the pusher 4 is slid back and forth by supporting the rod 25 and rotating the screw rod 25.

In the present invention having the above-mentioned structure, an operator sequentially puts a predetermined number of cup-shaped products 1 at predetermined positions on the supply conveyor 2 (see FIGS. 1 and 5 (A)). However, an automatic feeder may be used separately.

Then, the supply conveyor 2 is driven intermittently, and it is detected by the photoelectric tube 26 that the front cup-shaped product 1 has come to a fixed position, and the supply conveyor 2 is stopped.

The bag suction supply device 8 is actuated by the detection signal from the photoelectric tube 26 and the like, and the suction pads 10a, 10B, 10c and 10d constituting the bag suction supply device 8 move the uppermost bag 7 in the bag magazine. Adsorbing and carrying out the conveyor 11
Then, the bag 7 is transferred to the bag opening device 5, the opening seal device 6 and the carry-out conveyor 11 by the traverse device 30 as it is (see FIG. 5B).

At this point, the carry-out conveyor 11 is stopped. Next, the lower suction pads 12 are respectively lifted by the cylinders 29 from below the two suction pads 10a and 10b on the side of the supply conveyor 2, and the lower suction pads 12 are sucked onto the lower surface of the opening of the bag 7. The lower surface of the opening is fixed.

Next, the suction pads 10a and 10b constituting the bag suction supply device 8 are raised to a predetermined height, and the opening of the bag 7 is opened (see FIG. 5C).

When the opening of the opening of the bag 7 is detected, the guide portion 14 supported by the first donut-shaped disc 15 and the second donut-shaped disc 16 by the cylinder 22 is moved forward. And the tip of the guide portion 14 is inserted into the opening of the bag 7, and at the same time, the guide portion 1 is moved by the cylinder 21.
The strips 14a, 14a, ... Constituting 4 are expanded, and the opening of the bag 7 is opened in a substantially circular shape (see FIG. 5D).

Next, when the tip end of the guide portion 14 is detected to be expanded, the pusher -4 is moved to the cup-shaped product 1 by the cylinder 24.
5 (E), the screw rod 25 is rotated at the same time, the pusher-4 is advanced, the rear part of the cup-shaped product 1 is pushed, and the cup-shaped product 1 is The bag 7 is filled from the guide portion 14 (see FIG. 5).
(D)).

After that, when the filling of the cup-shaped product 1 into the bag is completed, the pusher 4 is returned to the rear by the screw rod 25 while maintaining the horizontal state, and when the pusher 4 is removed from the guide portion 14, the pusher 4 is returned to the rear and the cylinder is returned. It is gradually raised by 24. That is, the cup-shaped product 1 is returned so as not to come into contact with the subsequent cup-shaped product 1 and is prepared for the next step.

Further, after confirming the return of the pusher-4, the guide portion 14 is also returned to the rear by the cylinder 22, and the cylinder 21 causes the strips 14a, 14a ...
・ Be prepared for the next process.

Next, the folding plates 27 advance from both sides of the opening of the bag 7 to the folds in the upper and lower central portions thereof to enable accurate folding and heat bonding (FIGS. 5F and 5G).
reference). In addition, it is advisable to blow air into the folds as needed in accordance with the advance of the folding plate 27.

Next, the bag openings are suction pads 10a and 1a.
0b and the lower suction pad 12 are closed, and the seal bars 13a and 13b constituting the mouth seal device 6 sandwich the bag opening portion and heat bond it (see FIG. 5 (H)).

When the sealing of the bag opening is completed, the carry-out conveyor 11 is intermittently driven, and the packed cup-shaped product 1 is transferred to the rear side and further, for example, in the box packing direction.
