As shown in FIG. 9, the outlet IO of the hopper 5 is slightly offset from the center of the hanger bar 6 due to the flow of paddy inside the hopper, but the metal fitting 57 is located at the center of the paddy bag 7.
That is, it is located at the center (L/2) of the hanger par 6.

Next'(ζ), the operation of this embodiment having the above-mentioned configuration will be explained.

Magnet bracket 29 and arm 30 of paddy bag feeding device 9
is waiting at position A in FIG. When the start button 512 (see FIG. 1) of the first light loading device is pressed in this state, a start command pulse SP is output from the start button S12 to the microprocessor 71, as shown in FIG. 71
is in the automatic control state (i.e. “] in the figure) as shown in Figure 1bl.
The microprocessor 71 immediately instructs the transport motor 22 to move the support 27, and the transport motor 22 rotates in the normal direction as shown in FIG. 01. and connect the support to the seventh via the chain 26.
Move from the figure to the mouth. At this time, the arm 30 is in an open state as shown by the chain line by the case cam surface 21g. The position of the supporter 27 is determined by the microphone processor 71 periodically detecting the output XI (see FIG. 19(c)) of the potentiometer S7 connected to the transport motor 22 that drives the supporter 27. It can be judged by this.

In this way, when the support 27 reaches the paddy bag storing position, the magnet 29a of the bracket 29 comes into contact with the metal fitting 55 of the paddy bag 7, and the paddy bag 7 becomes one piece! The reversing switches S5 and 36 are actuated by the suction and further suppression by the bracket 29. When reversing switches 35, 86 are activated together, switches S5. From S6, a pulse signal x2 is output as shown in FIG. As a result, only one paddy bag 7 is conveyed forward based on the attraction of the magnet 29a, and in the middle of the conveyance, the arm 30 moves to the cam surface 21.
The paddy bag 7 is switched to the clamping position by a, and the paddy bag 7 is reliably conveyed to the c position by attraction by the magnet 29a and backing by the arm 30.

At this time, the other end of the paddy bag 7 is temporarily fixed by a bag stopper 36 made of a flexible body, as shown in FIG. 5, so that the paddy bag 7 is stretched diagonally and tightly.

When it is determined that the holder 27 has reached position C, the microprocessor 71 switches the bag opening device drive motor 41 to the 19th position.
Each gear 4 is rotated in the downward direction as shown in the figure [kl].
The arms 42.43 are synchronously rotated downward via 0a to 40d and 40e, and the magnets 47 of the pair of adsorption devices 45 are attached to the metal fittings 57 on both sides of the rice bag 7 which is in a stretched state. to collide.

The arms 42 and 43 are lowered, the signal x3 of the lower limit switch SIO is turned ON as shown in FIG. Then, the bag stopper solenoid 61 is turned on as shown in the same figure (υ), and the bag stopper 36 is retracted and the engagement between the stopper 36 and the paddy bag 7 is released. 811 ON
Based on this, the microprocessor 71 causes the motor 22 to rotate forward as shown in FIG.
The support 27 is retreated to position 2 of the hopper outlet 10. When it becomes clear from the output x1 of the potentiometer S7 that the support 27 has reached position 2, the microprocessor 71 reverses the bag opening device drive E-taper 41 to move the arms 42, 43 upward. , 43 of upper limit switch S9
No. X4 is switched from the OFF state to the O
Rotate until the N state is reached. As a result, the metal fittings 57 sewn on both sides of the paddy bag are attracted to the magnets 47 of the suction device 45, and the empty bag 7 is opened, and at the same time, the hem of the paddy bag 7 is loosened by the upward movement of the suction device 1i45. is removed. When the signal X4 of this upper limit switch S9 is turned on, the bag stopper solenoid 61
is turned off, the bag stopper 36 returns to a state in which it can engage with the paddy bag 7 again, and the next paddy bag 7 is carried out 1ζ by the support 277.

Note that due to the attraction of the metal fitting 57 of the magnet 47, the actuator 51 enters against the return spring 52, and the first
The four open bag detection switches 511 connected in series shown in FIG. 8 are turned ON as shown in FIG.
If there is a paddy bag in one row but there are no paddy bags in other rows, any of the following may occur: a paddy bag separation error, a transport error, a paddy bag opening error, etc. Since the metal fitting 57 of the rice bag 7 is not attracted to any of the devices 45, the switch S]
] remain in the OFF state, and the microprocessor 71 is in the ON state (No. 8 An abnormality is detected and the alarm lamp 72 and alarm buzzer 73 (not shown in FIG. 18) are activated to notify the operator of the abnormality.
FJ bag f'"Work 1 If there is no empty bag 7 between both magnets 47, the opposing magnets 47 will repel because they have the same polarity,
Therefore, the magnets 471Fi1 do not attract each other and place an excessive load on the ffff bag device driving motor 41, and the arms 42 and 43 can be easily rotated in the -F direction.

Then, the shutter 11 closes and the closed position detection switch S
3 is in the ON state (Fig. 19 [hl], all the open bag detection switches 511 are ON, that is, the two rows of paddy bags have been opened without any trouble (Fig. 21 (a)), and the hopper When a small amount of paddy m accumulates in the paddy sensor 51 and the output signal from the paddy sensor 51 turns ON (Fig. 21 [bl l tel l
As shown in FIG. 19, the chassis opening/closing motor 20 is driven until the signal X6 of the opening/closing position detection switch S2 is turned ON, the auto shutter 11 is lowered, the hopper outlet 10 is opened, and the paddy is removed. m is supplied to the paddy bag 7 (FIG. 21(d)).

At this time, a predetermined tray of paddy m is thrown into the open paddy bag 7 at once, so as shown in FIG. Counting arm flow 0
Even if it is on the left side in the figure, the weight of the paddy m that has been dropped and thrown in is corrected to the normal paddy feeding position on the right side of the back support arm 70, and the subsequent feeding of the paddy m and the movable paddy receiver The full bag can be smoothly moved out of the space A by the floor 62 (FIG. 21(d)).

Simultaneously with the supply of paddy, the paddy bag dispensing device 9 linked to the Eaton Yatta-11 moves upward as shown by the chain line in FIG. When the magnet bracket 29 and the arm 30 do not interfere with the paddy bag 7, the conveyance motor 22 moves as shown in FIG.
), the bracket 29 and the arms 3o1. ! It is moved backward and moves to the standby position 1ζ. On the other hand, when the paddy bag 7 is opened by the suction device 45, it is in a slightly lifted state, and when the paddy bag 111 becomes heavy due to the supply of paddy to the paddy bag 7, the paddy bag 7 becomes heavy due to its weight. is removed from the suction device 45 (FIG. 21(e), and at this time, the switch Sll is in the O+rF state as shown in FIG. 19 (gl).

). Furthermore, even if the paddy bag 7 is removed from the opened state by the suction device 45, since the shutter 11 has been lowered and is positioned inside the paddy bag 7, filling of paddy can be continued without any problem, and the paddy bag 7 can be filled with paddy without any trouble.
When the paddy is fed, the paddy becomes full and the discharge port 10 is overflowing, and the paddy sensor S1 is turned on again (FIG. 21(f)). Then, the shutter 11 opens and the close position detection switch S2 turns to O as shown in FIG.
Since it is in the N 1/8 state, the auto shutter 11 (
(Fig. 21(g)).

At the same time as the shutter 11 is raised, the feeding device W9 is lowered, and the magnet bracket 29 and arm 30 are returned to the initial standby position A.

FIG. 22 shows the outputs and driving conditions of each sensor and motor during the process of transporting the paddy bag 7 from the storage position opening, opening the bag, and inserting the paddy. In the figure, "1" indicates an ON state of a switch or motor, and "0" indicates an OFF state. Furthermore,
Sample times 1, 2...19 are sample times ■ in FIG.

■...Compatible with [phase].

In this way, the first paddy bag 7 is full of paddy and the shutter 1
Even when hopper 1 is closed, paddy continues to be charged and stored in hopper 5, but as shown in FIG.
When the full sensor 75 provided at the top detects paddy m, the microprocessor 71 drives the alarm lamp 72, alarm buzzer 73, etc. to notify the operator that the hopper 5 is full. Therefore, the worker
to stop further reaping and threshing. Next, the operator gets off the driver's seat 2 and operates the hydraulic operating lever 76 shown in FIG. Then, Fig. 23 t
As shown in e+, the floor feeding solenoid valve 77 shown in FIG. 18 is turned on and driven, the hydraulic circuit is switched by the valve 77, and the drive cylinder 65 is driven as shown in FIG. 17. The floor 62 of the movable rice receiver is moved in the direction of the arrow together with the full rice bag 7 (FIG. 21(1)). Floor 62 of the mobile paddy receiver is D.
When the auxiliary paddy tray has moved to the floor 64, the bracket 62a comes into contact with the switch 67, and the output signal X7 is turned on as shown in FIG. , 1, the driving of the drive cylinder 65 in the B direction is also stopped, and the floor 62 is also stopped.

In this state, the worker lowers the full paddy bag 7 on the floor 62 onto the field using the movable paddy receiver, but it is moved! The paddy bag 7 is reliably moved in the D direction by the back support arm 70 that stands up in the E direction as the floor 62 moves in the D direction. The auxiliary paddy receiver of the paddy bags is taken out by the operator to Futa Aro 4, and the work of discharging them to the field is performed smoothly. In this way, when the full paddy bag 7 on the floor 62 is released into the field, the mobile paddy receiver detects the presence of the paddy bag 7 on the floor 62 until then. The bag detection sensor 69 changes from the state in which the light 79 from the light emitting part 69& was blocked by the paddy bag 7 to the state in which the light 79 reaches the light receiving part 69b, and the output signal x8 of the sensor 69 becomes , 23rd
As shown in Figure (C), the OFF state changes to the ON state. In response, the microprocessor 71 turns the floor storage solenoid valve 80 into the ON state as shown in Figure 1dl.
By changing the FF state to the ON state and driving the drive cylinder 65 in the opposite direction by switching the hydraulic circuit, the movable paddy receiver moves the floor 62 from the previously protruding state to the in direction, and the bracket 62b abuts the switch 66. move it to. When the bracket 62b comes into contact with the switch 66, the output signal X9 from the switch 62 is in the OFF state, which indicates that the movable paddy receiver is in the state where the four arrows 2 protrude in the direction D, as shown in FIG. The signal changes to the ON state, and the movable paddy receiver informs that the feeder 2 has been positioned at a predetermined position suitable for putting the next paddy into a new paddy bag.Signal X
9 is turned on, the microprocessor 71 stops driving the valve 80 and therefore the drive cylinder 65, and the movable paddy receiver stops the floor 62 (FIG. 21 (kJ)).

It should be noted that when the movable paddy receiver moves in the incoming direction of the floor 62, it can be moved manually by the operator by operating the hydraulic control lever 76, without relying on the bag detection sensor 69 as in this embodiment. Of course it is also possible.

Therefore, the worker presses the start button S12 again,
The microprocessor 71 is commanded to put paddy into a new paddy bag 7 from the hopper 5. Then, the support 27 moves according to the time chart 1- in FIG. 19, and the paddy bag 7 is pulled out from the storage position opening on the left side in FIG. The bag is opened by I37, but the shutter 11 is opened at the first time when the paddy sensor SL detects the paddy and the first time (Fig. 19 @).
Figure 9 (As shown in the middle, the motor 20 was driven, but from the second time onwards, the rice sensor S1 constantly detected the rice in the hopper as shown in Figure 21 (1). As soon as the open bag detection switch Sll is turned ON and the paddy bag 7 is opened and set below the discharge port 10, it is immediately opened and filling of paddy from the hopper 5 is started. When the motor 20 is driven and the shutter 11 begins to open, the microprocessor 71 immediately instructs the timer 82 to start timing for 'r seconds. When the paddy was put in,
Drive the motor 20 in the opposite direction to close the shutter 11. (FIG. 21 f-2 (, +1) When a predetermined amount of paddy has been put into the paddy bag 7, the operator operates the hydraulic operating lever 76 in the same way as in the case described above, and the movable paddy receiver is moved to the floor 6.

is released into the field, and the start 4' button S12 is pressed again to enter the next feeding cycle. After repeating this cycle several times, the paddy in the popper 5 disappears, as shown in Figure 21 fpl.
As shown in FIG. 21 (ql), when the paddy sensor S] changes from the ON state to the OFF state in which no paddy is detected, regardless of the elapse of time 'r seconds, as shown in FIG. Then, the operator presses the start button S12 again, returns to the driver's seat 2 after setting a new paddy bag, and resumes operation of the combine 1.

In addition, during the normal transporting and opening operation of the paddy bag 7, as shown in FIG. 24, each time the start button S1.2 is repeatedly pressed, the microprocessor 71 controls the
As shown in fbl in the same figure, a 1" state does not indicate an automatic state (set state), and a 0" state indicates a non-automatic state (reset state).
Switch between states.

This allows the main switch 8 of the combine harvester 1 to
It is possible to reset the automatic state and restart the operation from the beginning by simply pressing the start switch S12 without disconnecting the shutter 11.However, during the opening operation of the shutter 11, i.e. During paddy feeding operation,
Due to the reset and set instructions from the start switch S12, the movable paddy receiver has already applied the paddy force τ onto the floor 62, and a new paddy bag 7M is added even though there is a first paddy bag 7.
In order to prevent the movable paddy receiver from being conveyed onto the floor 62, the microprocessor 71 (FIG.
As shown in 1, the reset command from the start switch '5ill is accepted.

Furthermore, if the operator disconnects the main switch 81 of the combine harvester 1 with the shutter 11 open, the next time the main switch 81 is connected and the combine harvester 1<in 1 is operated, the start button is pressed. If you forget to press 312 and leave the shutter 11 open, the paddy bag 7 is still set with paddy. As shown in the figure, when the main switch 81 power τ is cut off, the power relay is held for 8 seconds as shown in the figure te+, and during that time, the microprocessor 71 operates the shutter 11 opening/closing motor 20. upper limit switch S3 is ON
The shutter 11 is driven until it is closed, and then when the main switch 81 is turned on, it is controlled so that the shutter 11 is always closed.

As described above, according to the present invention, the start button 312 instructs to start the cycle of charging paddy into the paddy bag 7.
A feeding cycle start command means such as a paddy bag feeding device 9 which stirs the paddy bag 7 from the paddy bag storage position opening to below i<-5, an automatic paddy bag opening and removal device Open bag packaging v! Bag opening means such as 137, shutter 11 of hopper 5
A shutter opening/closing means such as a shutter opening/closing motor 20 for controlling opening and closing, a paddy sensor-Sl for detecting the amount of paddy introduced into the paddy bag 7, a timer 82, etc., are provided, and a charging cycle start command means is provided. In response to the command pulse SP, which is a start signal from 7 is opened, and with the paddy bag opened, the shutter opening/closing means is driven to open the shutter 11, and the paddy in the hopper 5 is thrown into the opened paddy bag 7, and the paddy is removed. When it is determined that a predetermined amount of paddy has been put into the paddy bag by the input amount detection means, the shutter driving means is driven again to close the shutter 11 and the paddy is transferred to the paddy bag 7 into the hopper 5. Since the loading is stopped, everything from pulling out the paddy bag, opening the bag, and even loading the paddy from the hopper 5 can be done automatically without manual intervention.
Compared to the conventional method, it is possible to perform the process with much greater physical comfort, and work efficiency can be greatly improved.
