Next, the movable bag clamping piece 20 connected to the piston of the cylinder 21 moves forward toward the fixed bag clamping piece 19 due to the drive of the cylinder 21, and the side end of the bag 12 moves with the fixed bag clamping piece 19. The bag 12 is held between the bag 12 and the side bag holding pieces 20, and the bag 12 is suspended with the opening portion facing sideways.

(Fig. 4A) Subsequently, each suction cup 13°16 disposed opposite the outer edge of the opening of the bag 12
The suction cups 13 and 16 connected to the positive pressure pipes 14 and 17 are activated to attract the outer edge of the opening of the bag 12 by the operation of the depressurization generating device. adsorbs.

While maintaining this suction, the pistons of each cylinder 15.18 connected to each suction cup 13.16 move back, and the outer edge (outside) of the opening of the bag 12 is forced to move as shown in FIGS. 1 and 2. It is adsorbed and opened.

On the other hand, pre-weighed enoki mushrooms are sent from the hopper 1, which is the input port, and the enoki mushrooms are supplied onto the semi-cylindrical enoki mushroom mounting plate 2, which is movably arranged below the hopper 1, and then the enoki mushrooms are placed on standby. There is.

(Fig. 4B) When the opening of the bag 12 is suctioned and opened by the suction cup 13.16 as described above, the piston of the cylinder 11 connected to the plate 7 moves forward, and the pair assembled on the plate 7 moves forward. Insert the tip of the rotating plate 6 into the opening of the bag 12.

(Fig. 4C) Next, the pistons of the cylinders 3 and 5 connected to the enoki mushroom mounting plate 2 and the retreat prevention piece 4 move forward, and with this movement, the tip of the enoki mushroom mounting plate 2 first moves to the plate 7. When the enoki mushroom mounting plate 2 moves forward, the outer side surface of the enoki mushroom mounting plate 2 contacts the inner walls of the pair of rotating plates 6 supported by the plate 7 and the upper surface of the elastic restraining piece 9 whose base end is fixed to the plate 7. presses the inner walls of the pair of rotating plates 6, and the distal ends of the rotating plates 6 are opened about the respective support shafts 8 against the respective spring members 10, and as a result of this opening, the distal ends of the rotating plates 6 are opened. Bag 1 on the side
The inner surface of the opening portion of No. 2 is expanded and supported.

At the same time, the outer bottom surface of the enoki mushroom mounting plate 2 presses the upper surface of the tip side of the elastic deterrent piece 9 downward, and the tip side of the elastic deterrent piece 9 is pushed down against the self-resilience of the deterrent piece 9. , the tip side of this pressed down elastic restraint piece 9 is the bag 12
The inner bottom surface of the opening part is expanded and supported.

In this state, the enoki mushroom mounting plate 2 and the retreat prevention piece 4 are inserted into the bag 12.

(Fig. 4D) Next, the piston of the cylinder 3 connected to the enoki mushroom mounting plate 2 moves backward, and the enoki mushroom mounting plate 2 is removed from the bag 12.
At the same time as the enoki mushrooms are pulled out, the enoki mushrooms placed on the enoki mushroom mounting plate 2 are removed from the bag 1 without moving back due to the retreat prevention piece 4.
It remains within 2.

At this time, the pair of rotating plates 6 and the elastic restraining pieces 9 come into contact with the outer circumferential surface of the retreat blocking piece 4 in an elastic state, and as a result, the distal end side of each rotating plate 6 maintains the open state, and
The elastic restraint piece 9 continues to be pressed down.

(Fig. 4E) Then, the piston of the cylinder 5 connected to the backward blocking piece 4 retreats, and the backward blocking piece 4 moves back to the bag 12.
At the same time as it is pulled out, the distal ends of the pair of rotary plates 6 are closed in a V-shape by the elastic action of the spring member 10, and the distal ends of the elastic restraining pieces 9 are lifted by their own elastic restoring force.

(FIG. 4F) Subsequently, the piston of the cylinder 11 connected to the plate 7 retreats, and the rotating plate 6 and the elastic restraining piece 9 are separated from the rim of the opening of the bag 12. The suction force of the suction cups 13 and 16, which were suctioning the outer edge, is cut off and they retreat.

(Fig. 4G) Next, the piston of the cylinder 21 connected to the movable bag clamping piece 20 retreats, and the side end of the bag 12 that was clamped between the fixed bag clamping piece 19 and the movable bag clamping piece 20 The bag 12 containing the enoki mushrooms is placed on the receiving plate 22 from the falling part.

(FIG. 5A) At this time, each of the suction cups 13 and 16 is prepared for the next suction operation on the edge of the opening of the bag 12.

Further, the receiving plate 22 on which the bag 12 containing the enoki mushrooms is placed moves forward to a position directly below the elastic presser 28 as the piston of the cylinder 24 connected to the support body 23 moves.

(Fig. 5B, Fig. 6A) Next, the piston of the cylinder 29 connected to the elastic depressor 28 descends and the elastic depressor 28
At the same time, the piston of the cylinder 36 connected to the pair of bag indenters 35 moves forward and protrudes from above the receiving plate 22. A bag indenter 35 clamps the opening edge of the bag 12.

(Fig. 6B) Next, the piston formed integrally with the rack 38 is actuated by the drive of the cylinder 39, and the gear 37 meshed with the rack 38 rotates due to the actuation of the rack 38, and in conjunction with this rotation, the above-mentioned bag The clamp indenter 35 rotates while holding the opening edge of the bag 12, and the edge of the bag 12 is twisted.

(FIG. 6C) At this time, since the elastic presser 28 gently presses and holds the bag 12 on the receiving plate 22, only the mouth edge of the bag 12 is twisted.

Then, the piston of the cylinder 31 connected to the heating element 30 is lowered, and the cylinder 33 connected to the retainer 32 is lowered.
The piston rises, and the rim of the twisted bag 12 is sandwiched between the heating element 30 and the retainer 32, and the heating element 30 and the retainer 3
It is heated with a heater 34 embedded in 2 to seal and seal it.

(FIG. 6D) Almost in synchronization with this heating-induced sealing operation, the elastic presser 28 holding the bag 12 on the receiving plate 22 under soft pressure returns to its original position as the piston of the cylinder 29 rises. A pair of bag indenters 35, which were holding the mouth edge of the bag 120, are released by the backward movement of the screws I and N of the cylinder 36.

(Fig. 6E) Then, when the mouth edge of the bag 12 is sealed by the heating element 30 and the retainer 32, the piston of the cylinder 31 rises, and the screws of the cylinder 33 descend, causing each cylinder to The heating element 30 and the retainer 32 connected to the respective pistons 31 and 33 return to their original positions.

(FIG. 6F) After this return is completed, the piston of the cinder 25 connected to the receiving plate 22 via the arm 26 descends, and the receiving plate 22 rotates approximately 90 degrees around the shaft 27. The enoki mushrooms sealed in the bag 12 are transferred to the receiving plate 2 by the rotational movement.
It is carried out from 2.

(FIG. 7A) After this unloading, the rack 38 is returned to its original position by the drive of the cylinder 39, and the screws of the cylinder 25 are raised so that the receiving plate 22 rotates about the shaft 27. rotates 90° in the opposite direction.

(FIG. 7B) Next, the cylinder 2 connected to the support 23
With the movement of the piston 4, the receiving plate 22 moves back and returns to the position directly below the stationary bag holding piece 19, in preparation for the next feeding operation of the bag 12 and enoki mushrooms.

Therefore, according to the present invention, when the receiving plate 22 is moved forward to a position directly below the elastic presser 28 and the opening portion of the bag 12 is moved toward the bag clamp indenter 35, a portion of the receiving plate 22 protrudes. Even if the opening of the set bag 12 hangs downward, one of the heating means, in this case the heated engager 32, is kept on standby further below the opening of the bag 12 by the drive of the cylinder 33. This can prevent damage caused by contact with the cylinder 36.
．． When the bag clamp indenter 35 driven by 39 pinches the opening of the bag 12 and twists it, the opening of the bag 12 is removed without causing any positional interference between the heating element 30 and the retainer 32, which are heating means. can have a predetermined shape, and in this state, the heating element 30 and the retainer 32 are connected to the cylinder 31.
33 is driven, the opening of the bag 12 moves upward and downward towards the twisted part to securely seal the twisted part, and at this time, the thin part of the bag 12 other than the twisted part is sealed. The enoki mushrooms can be neatly sealed in the bag 12 without being damaged by contact with the heating means, and the enoki mushrooms can be neatly sealed in the bag 12 without being damaged by contact with the heating means.
It has the excellent advantage of being packaged neatly and hygienically within 2 hours, increasing its commercial value.

In addition, it is possible to provide a series of motion feeding mechanisms in which the bag 12 containing the enoki mushrooms is placed on the receiving plate 22 and the receiving plate 22 moves from the previous process to the next process by reciprocating movement. It also has a mechanism for transporting the sealed bag 12 by the rotational movement of the plate 22, thereby eliminating the need to separately provide a transport mechanism and a transport mechanism for the bag 12.
