It is designed to move into position.

When the piston 26 is fully retracted, the front cam 27a is connected to the push rod 18,
19, the rear cam 27b is located behind the rear push rod 19, and is configured to prevent both push rods 18, 19 from being pushed in at the same time.

Reference numeral 28 denotes an empty bag take-out arm whose base is fixed to the cam bar 27. When the piston 26 is fully retracted, a rotating piece 28b with a magnetic body 29 rotatably attached to the tip of the take-out arm 28 moves to the crank 12. Paddy bag 9' facing downward and held between stoppers 10 and 11
The magnet 29 is adapted to be attracted to an iron piece 9c attached to the shoulder of the holder. 30 is a spring that biases the rotating piece 28b in the direction of the iron piece 9c.

Note that when the piston 26 is fully extended, the empty bag removal arm 28
The actuator 24 is regulated so that the paddy hopper 4 moves to a position below the paddy hopper 4. Further, the actuator 24, the crankcase 12, etc. are provided symmetrically with respect to the rice bag 9, and the left and right actuators are connected so that their operations are synchronized.

The present invention is constructed as described above, and when storing a plurality of empty paddy bags 9 in the empty bag storage position A in advance, the actuator 24 is first operated to push the piston 26 into the empty bag storage position A. When the cam bar 27 is moved into the position, the front cam 27a moves to the rear of the push rod 18 and the rear cam 27b moves to the rear of the push rod 19, as shown in FIG. Abutting against the flat portion 27c of the cam bar 27, both the front and rear stoppers 10, 11 are in the lowered position.

Therefore, a plurality of empty rice bags 9 are inserted through the holes 9a and 9c.
Insert it into the guide bars 8, 8 using the. Then, when the clasp 15 is released, the crankcase 12 is moved to the fourth position.
Since the paddy bag passage is opened by rotating upward as shown by the chain line in the figure, the empty paddy bag 9 is moved by the spring 8a.
The crank case 12 is lowered and fixed with a stopper 15 with the front and rear sides of the frontmost rice bag 9' sandwiched between the stoppers 10 and 11.

Next, the magnets 29, 29 provided on the rotary piece 28b of the empty bag removal arm 28 are connected to the iron pieces 9 provided on both shoulders of the paddy bag 9'.
c, 9c, and operate the actuator 24 to make the piston 26 protrude.

In this protrusion stroke, the movement of the cam bar 27 first causes the front push rod 18 to move toward the cam 27a.
In conjunction with this, the bell crank 20 rotates as shown by the arrow in FIG. 5, and the stopper 10 rises to open the front passage of the rice bag 9' at the forefront. The paddy bag 9' supported by the bag attachment arm 28 is fed forward through the passage through the magnet 29.

At this time, the rear stopper 11 is in the lowered state and the feeding passage is closed, so even if the hem of the frontmost paddy bag 9' and the hem of the adjacent paddy bag 9 overlap or become tangled. The adjacent rice bags 9 are reliably prevented from moving by the stopper 11 without being taken out by the feeding of the foremost rice bag 9'.

When the cam 27a passes through the front push rod 18, the front bell crank 20
Rotates in the opposite direction due to the action of the stopper 1
0 is lowered and the paddy bag passage is closed. When the cam 27b pushes the push rod 19 at the rear, the rear bell crank 21 rotates in the direction of the arrow and the stopper 11 at the rear rises, thereby opening the paddy bag passage below the stopper 11 to store empty bags. The entire rice bag 9 is pushed out to position A by the action of the spring 8a, so that the frontmost one hits the front stopper 10 and is held at the frontmost position. Next, when the cam 27b passes through the push rod 19, the rear bell crank 21 moves to the winding spring 23.
Rotates in the opposite direction due to the action of the stopper 1
1 descends to the rear side of the rice bag 9' at the forefront.

When the piston 26 reaches the most protruding position, the paddy bag 9 supported by the empty bag removal arm 28 via the magnet 29
moves below the paddy hopper 4. There, paddy bag 9
The opening of the machine is made to face the discharge port 4a, and paddy is stored therein, and when it is full, it is taken out of the machine.

Next, actuator 24 is operated to retract piston 26. Then, as the cam bar 27 moves, the push rod 18 at the front moves vertically and reciprocally by the cam 27b at the rear, and the front bell crank 20 and stopper 10 swing up and down. Since the rear stopper 11 is in the lowered state and the paddy bag passage remains closed, the paddy bag 9 does not move, and the rear cam 27b continues.
As a result, the rear push rod 19, rear bell crank 21, and stopper 11 operate, but at this time, the front stopper 10 remains in the lowered state, so the paddy bag 9 does not move.

Continue to press the push rod 18 of the front cam 27a.
Due to the contact, the front bell crank 20 and the stopper 10 swing up and down, but since the rear stopper 11 remains in the lowered state, the rice bag 9 does not move.

When the piston 26 is fully inserted, the magnet 29 of the rotary piece 28b provided at the tip of the empty bag take-out arm 28 attracts the iron piece 9c on the shoulder of the rice bag 9' at the front, so operate the actuator 24 again. piston 26
The paddy bag 9 is automatically fed out below the paddy hopper 4 as described above.

(Effect of the invention) The tension of the spring installed at the base of the guide bar,
By opening and closing the paddy bag passage of the front and rear stoppers that operate alternately and in a predetermined order, the paddy bag is once held at a constant frontmost position and then fed out in the direction of the paddy hopper. Unexamined Japanese Patent Publication 1983-
Unlike No. 98623, the feeding position of the paddy bag fluctuates, and the feeding device can be made into a simple configuration without requiring a complicated control device for the rice feeding device. Even if a paddy bag in a section and an adjacent paddy bag overlap at the hem part, the paddy bags can be reliably fed out one by one by the sorting action of a stopper without taking out the adjacent paddy bag at the time of feeding.
