Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic auger storage device for moving an auger for discharging grain from a grain tank provided in a combine harvester from its working position to a predetermined storage position inside the machine body.

``Prior art'' A means for automatically retracting the auger from the working position to the storage position by controlling the drive member that rotates the auger vertically and horizontally was developed in the 1980s.
This method is disclosed in Japanese Patent Application Laid-open No. 1-12193, Japanese Patent Application Laid-open No. 81-227708, and Japanese Utility Model Application No. 82-85058.

``Problems to be Solved by the Invention'' When a conventional automatic auger storage means is equipped with a manual priority means, the following problems arise. If automatic storage is subsequently resumed from the interrupted state, the auger position after manual operation will have been changed. In particular, in order to manufacture the auger as inexpensively as possible, we do not control the vertical and horizontal positions of the auger by inputting them into the CPU using potentiometers, etc., but for example, we only control the minimum number of limit switches and the operating times of the vertical and rotational times. If you try to perform automatic storage according to a specified schedule, the position of the auger cannot be determined, so the auger may start rotating even though the upward movement of the auger is insufficient, causing the auger to collide with the tank. There was a risk of causing a major accident.

"Means for Solving the Problems" However, the present invention provides a grain tank, an auger capable of discharging grains from the tank to the outside of the machine, an auger vertical movement means for vertically moving the auger, and an auger for horizontally moving the auger. In a combine that is equipped with a rotating means and an automatic storage means that stores the auger from a working position to a storage position by specifying the operation of the auger vertical movement means and rotation means, an automatic storage system that controls the operation and stop of the automatic storage means. a switch, a manual switch for the auger vertical movement means and rotation means, and a means for interrupting automatic storage by operating the automatic storage switch during automatic storage and restarting the automatic storage after being interrupted by operating the automatic storage switch again. , a manual priority means that stops the operation of the automatic storage means and holds it manually when the manual switch is operated, and a manual priority means that stops the operation of the automatic storage means when the manual switch is operated and performs manual holding, and a manual holding means that cancels manual holding and restarts the operation of the automatic storage means from the beginning when the automatic storage switch is operated during manual holding. It is characterized by having a means.

``Function'' Therefore, when an operator senses danger during automatic storage, the automatic storage switch is operated to immediately stop and hold the auger to ensure safety. Furthermore, when the storage switch is operated again, the work is resumed from where it was interrupted, eliminating unnecessary operations and improving work efficiency.

In addition, if the auger is moved by the operator's intention during automatic storage, safety is ensured by automatically resuming storage from the beginning by operating the storage switch, and it is also possible to move the auger to any position from the beginning with the automatic storage operation. It can be stored reliably even after it has been removed.

~ (76) is turned on to interrupt the automatic storage and give priority to manual operation, and then touch the automatic storage switch (72) 11 times to restart the automatic storage operation from the beginning, During storage, press the storage switch (7)
2) Interrupt the automatic storage by touching
After that, when the storage switch (72) is touched again, the automatic storage is resumed from the point where it was interrupted, and the right rotation of the auger cylinder (26) is stopped by the limit switch (53).
) and the rotation time setting, and only when the clockwise rotation of the auger tube (26) has stopped in time (if the clockwise rotation is stopped by the limit switch (53), it will directly shift to the lowering operation), It is configured such that the transition to the lowering operation is not made to proceed to the next stage of lowering operation, but by touching the storage switch (72) again.

In this embodiment, the reaping section (7
), the grains threshed in the threshing section (4) are stored in the grain tank (14), and the required special number auger (19
) (20) and (21), the grains in the grain tank (14) are taken out of the machine.

When taking out grains from the grain tank (10), first turn on the manual switch (75) for raising the auger to raise the auger tube (26) to a height where it comes off the augerless (82), and then By turning on the manual switch (73) for rotating the auger to the left, the two motors (34) and (35) are driven in normal rotation so as to rotate the gear shaft (41) in the same direction. As shown in FIG. 6, the auger cylinder (26) is rotated counterclockwise and the rotation is stopped at an appropriate position on the right outer side or rear outer side of the machine to take out the grains.

On the other hand, after the grain discharging operation, the auger tube (26) in the working position is automatically stored in the storage position (82), and the storage operation is shown in Figures 9 to 13.
The explanation will be given according to the flowchart shown in the figure.

In addition, FUS (rising flag), F
Each flag, R3 (clockwise rotation flag) and FDS (downward flag), is activated when the automatic storage switch (72) is touched.
Automatic storage (Automatic storage by rising or clockwise rotation or "0",
1”, the control circuit (71) sends information that storage is automatically stopped.
In addition, the FRT (raise clockwise rotation completion flag) flag is used to determine whether the automatic storage raise and clockwise rotation has been completed or not.
When the value is "1", information indicating that the T is complete is sent to the control circuit (71).

As shown in the flowchart of FIG. 9, first, in step 1, it is checked whether the auger cylinder (26) is in the storage position or not by checking the storage position and turning on/off the switch (θ7).

When the switch (67) is turned on, the auger tube (2) is placed in the storage position.
8), the automatic storage switch (72) is touched in step 2, and in step 3, if FRT is initially "0" and automatic storage has not been completed until the rising shaft is rotated clockwise, step In Step 4, the raising solenoid (73) is turned on to raise the auger cylinder (26), and in Step 5, measurement of the rising time of the auger cylinder (26) is started. Touch operation of storage switch (72) and manual switch (
If there is no on operation in steps 73) to (76) (step 6.
7) Proceed to step 8.

When the auger tube (28) has been raised for a certain period of time (corresponding to the specified height) in step 8, the solenoid (79) is turned off in step 9, and the auger tube (26) is raised.
The auger tube (2B) stops rising and proceeds to step 10, where the auger tube (2B) is rotated clockwise.

By the way, in step 6, storage suite 2 (72)
When is touched, the process advances to step 12.

In step 12, since the FUS is initially "O", it is determined that the auger tube (28) is being raised by automatic storage, and the process proceeds to step 13. In step 13, the ascent of the auger tube (28) is stopped, and in step 14 In Step 6.8.16, set the FUS flag to rlJ, interrupt the time measurement in Step 5 in Step 15, and stop when the storage switch (72) is touched again.
The automatic storage is interrupted and held, and the auger cylinder (28) is stopped. When the storage switch (72) is touched again in step 6, it is determined in step 12 that automatic storage is being stopped because FUS is rlJ, and the process proceeds to step 17.

In step 17, FUSI r(H) is set, and in step 18, the time measurement of step 5 is restarted, and the process proceeds to step 8. If the auger cylinder (26) has not been raised for a certain period of time in step 8, the process proceeds to step 16.Step 16 Since FUS is rQJ, it is determined that automatic storage has been resumed, and the process proceeds to step 4, where the auger tube (26) is first raised until a certain period of time has elapsed.

As shown in the flowchart of FIG. 10, in step IO, the right rotation relays (77) (77) are turned on to rotate the auger tube (26) clockwise, and in step 19, the clockwise rotation time of the auger tube (2B) is Start timing.

While rotating the auger tube (28) clockwise, press the storage switch (7).
2) Touch operation and manual switches (73) to (76)
If there is no turn-on operation (step 20.21), proceed to step 22. In step 22, when the auger cylinder (28) moves to the right rotation end and the right limit switch (53) turns off, in step 23, the right limit switch (53) is turned off. Rotating relay (7
7) Turn off (77) to stop clockwise rotation of the auger tube (28), and proceed to step 24, lowering the auger tube (26).

By the way, in step 22, the right limit switch (
53) is not turned off due to a failure or the like, the process proceeds to step 25. In step 25, the auger cylinder (26) rotates clockwise for a certain period of time (after the auger cylinder (26) starts rotating clockwise, the right limit switch (5)
3) is carried out for a slightly longer time than the time it takes to turn off), in step 26 the relay (77) (
77) to stop the clockwise rotation of the auger cylinder (28), and in step 27 set the FRT flag to ``rl'' and return via the manual switches (73) to (78) in step 11 and turn the storage switch off again. (72) is made to wait until it is touched. When the storage switch (72) is touched again in step 2, since the FRT flag is "1" in step 3, it is determined that automatic storage has been completed up to raising and turning to the right, and Skip the rotation and proceed to step 24, lowering the auger tube (26). As a result, if the limit switch (53) fails and does not turn off, by specifying the maximum drive time in hours, you can prevent motor seizure and battery over-discharge. This also prevents the operator from being mechanically stopped at the end of clockwise rotation for several seconds and then suddenly starting to descend, causing harm to the operator.

Further, when the storage switch (72) is touched in step 20, the process proceeds to step 28.
Since FR3 is initially "0", it is determined that the auger cylinder (2B) is rotating clockwise due to automatic storage, and the process proceeds to step 29. In step 29, the auger 0 (2
8) is stopped, and in step 30, the F
The flag R3 is set to "1", and the time measurement in step 19 is interrupted in step 31, and steps 20, 25.
Turn the 32 routing, interrupt and hold the automatic storage, and stop the auger tJ (2B). When the storage switch (72) is touched again in step 20, it is determined in step 28 that automatic storage is stopped because FR5 is rlJ, and the process proceeds to step 33.
In step 33, FR5 is set to "0", in step 34, the time measurement in step 19 is restarted, and in step 25
If the auger cylinder (26) is not rotated clockwise in step 25 for a certain period of time, proceed to step 32.
In step 32, since FR3 is "0", it is determined that automatic storage has been restarted, and the process proceeds to step 10, where the auger cylinder (26) is rotated clockwise until a certain period of time has elapsed.

As shown in the flowchart of FIG. 11, in step 24, the lowering solenoid (80) is turned on and the auger tube (
26) is lowered, and in step 35, the auger cylinder (26) is lowered.
6) Start measuring the descent time. mo and ogre (
2B) If there is no touch operation of the storage switch (72) or ON operation of the manual switches (73) to (78) during the descent (step 36.37), proceed to step 38. In step 38, the auger cylinder (2B) is stored in the storage position (i.e., augerless) CB2> and the storage position limit switch (67) is turned off, the process proceeds to step 40, and in step 40, the solenoid (80) is turned off and the auger cylinder (28) is rotated clockwise. It stops and the automatic storage of the auger tube (26) is completed.

By the way, in step 36, the storage switch (72)
When is touched, the process advances to step 41.

In step 41, since the FDS is initially "O", it is determined that the auger cylinder (26) is descending due to automatic storage, and the process proceeds to step 42. In step 42, the descent of the auger cylinder (26) is stopped, and the auger cylinder (26) is , the flag of the FDS is set to "1" in step 43, the time measurement in step 35 is interrupted in step 44, and the storage switch (7) is set to "1".
2) turns the routing to stop when touched again, interrupts automatic storage, and stops auger 0 (26). Then, in step 36, the storage switch (7
When 2) is touched again, it is determined in step 41 that automatic storage is being stopped because the FDS is rlJ, and the process proceeds to step 45.
DS is set to "O", and in step 46, the time measurement of step 35 is restarted, and the process proceeds to step 38, step 3
If the switch (67) is not turned off in step 8, the process proceeds to step 39, and in step 39 the auger tube (
26) has not been maintained for a certain period of time, the process proceeds to step 47. In step 47, it is determined that automatic storage has been resumed since the FDS is "0", and the process proceeds to step 24.
Lower the auger I (2B) until a certain period of time has elapsed.

As mentioned above, when the worker senses danger during automatic storage, if the operator touches the storage switch (72), [α] Immediately interrupts automatic storage to ensure safety, and then presses the storage switch (72) again. By touching 72), automatic storage can be resumed after it was interrupted, and unnecessary operations can be omitted.

On the other hand, during the automatic storage, manual switches (73) to (78)
) is turned on, manual holding is performed and automatic storage is stopped, and the operation is as shown in the flowcharts of FIGS. 12 and 13.

That is, in step 48, the manual switch for raising (
75) is turned on, the raising solenoid (78) is turned on in step 49 to raise the auger cylinder (2B) to an arbitrary height. When the lowering manual switch (7B) is turned on in step 50, it is checked in step 51 whether or not the auger tjl (28) is in the storage position, as in step 1, and the auger cylinder (2B) is in the storage position. If not, proceed to step 52; if there is, proceed to step 53. In step 52, the lowering solenoid (8
0,) to lower the auger cylinder (28) to an arbitrary height, and in step 53 turn on the lowering solenoid (80
) is stopped and held to prevent the auger cylinder (26) from descending.

In step 54, when the manual switch (70) for clockwise rotation is turned on, in step 55, it is checked whether the right limit switch (53) is on or off, and the auger cylinder (28
) is not at the right rotation end and the switch (53) is on, the process goes to step 56; when it is at the right rotation end and the switch (53) is off, the process goes to step 57. In step 56, the right rotation relay (77) (77) is turned on to rotate the auger cylinder (26) to an arbitrary position, and in step 57, the relay (77) (77) is held off to prevent the auger cylinder (26) from rotating clockwise. When the manual switch (73) for clockwise rotation is turned on in step 58, it is checked in step 59 whether the left limit switch (54) is turned off or not, and the auger tube (26) is not at the left rotation end and the switch ( When the switch (54) is on, proceed to step 60; when the switch (54) is at the left rotation end, proceed to step 61; in step 60, the left rotation relay (78) is turned off;
) (78) to rotate the auger cylinder (28) to an arbitrary position, and in step 61, turn on the relay (78).
(78) is held off to prevent left rotation of the auger cylinder (26). When the auger tube (26) is moved by turning on the manual switches (73) to (76), the process proceeds to step 62. In step 62, FUS, FR3, F
Set each flag of DS and FRT to "0", reset automatic storage that was stopped due to manual operation, proceed to step 1, and start automatic storage when the storage switch (72) is touched in step 2. This will ensure safety.
