Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a movement control device for a binding machine that performs binding processing of waste culms in a combine.

[Problems to be Solved by Prior Art and Invention] Generally, a binding machine provided in this kind of combine is arranged at a transport end portion of a culm carrier for transporting culms that have been threshed in a threshing unit, and A predetermined amount of discharged culm is bound at a predetermined position. By the way, since there are various types of culm such as long culm and short culm,
Depending on the culm, the binding position may deviate significantly from the desired position. Therefore, there is an attempt to perform a highly accurate binding by making the binding machine movable in the culm length direction and controlling the movement of the binding machine based on the length of the culm. However, even with this, the culm is conveyed with an inclination (when deeply handled in the threshing part, the culms are difficult to come out of the threshing part, so that the culm has an inclined posture preceded by the plant side). In such a case, since the bundling position is displaced, the same problem as in the fixed type occurs and the bundling process cannot be performed with high accuracy.

[Means for Solving the Problems] The present invention was conceived with the object of providing a movement control device for a binding machine in a combine, which can eliminate these drawbacks in view of the above circumstances. , A bundling machine for bundling waste culms transported by a carrier,
A combine is provided so as to be movable in the length direction of the transfer culm with respect to the machine body, and also has a movement control means for controlling the movement of the binding machine based on the inputted culm length information, in the combine machine and the machine body. An oscillating rod that oscillates and displaces as the machine moves is interposed, and the oscillating rod detects an oscillating angle of the oscillating rod, and outputs the detection signal to the movement control unit as a binding machine position. It is characterized in that a swing angle detecting means for outputting as a detection signal and a detection value correcting means for correcting the detection value of the swing angle detecting means by swinging the swing rod by a manual operation are connected. It is what

Further, according to the present invention, the detection value in the movement control of the binding machine can be corrected by a manual operation so that the binding can always be performed with high accuracy.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a combine aircraft, and the aircraft 1
In the rear part, a culm carrier 3 for transporting the culm that has been threshed by the threshing unit 2 to the rear is provided, and a binding machine 4 is provided at the transport end portion of the carrier 3. The culms transported by the carrier 3 are discharged to the outside of the machine after undergoing the binding process of the binding machine 4, and the like.

The binding machine 4 includes a packer 5, a needle 6, a door 7,
Although it is conventionally configured by various members such as the sweeper 8, this is configured such that the upper and lower support frames 9 and 10 supported on the machine body 1 side, the upper and lower brackets 11 on the binding machine 4 side,
12 engage with each other so as to be slidable in the left-right direction, so that they can move in the left-right direction with respect to the machine body 1. Reference numeral 13 is a spiral shaft rotatably supported on the machine body 1 side so as to be parallel to the lower support frame 10, and the spiral shaft 13 is provided with a spiral integrally provided on the lower bracket 12 on the binding machine 4 side. Boss 14 is screwed. Further, the base end of the spiral shaft 13 is interlockingly connected to the drive motor 15 via a reduction gear mechanism 15a. The binding machine 4 can be moved and displaced in the left-right direction by driving the drive motor 15 forward and backward.

Further, 16 is a swing rod pivotably supported on the upper portion of the binding machine 4, and the swing rod 16 is a detection lever of a potentiometer 18 provided on the binding machine 4 via a bracket 17.
Although engaged with 18a, the tip of the swing rod 16 is connected to a spiral shaft 19 which is rotatably supported on the machine body 1 side so as to be parallel to the support frame 9. That is, the spiral boss 20 is screwed onto the spiral shaft 19, and the engagement pin 20a projecting from the spiral boss 20 is engaged with the long hole 16a formed at the tip of the swing rod 16. There is. As a result, the swing rod 16 swings with the movement of the binding machine 4, and this swing angle is the operation of the adjustment handle 21 integrally connected to the base end of the spiral shaft 19. Thus, it can be changed by rotating the spiral shaft 19 and moving the spiral boss 20.

On the other hand, reference numeral 22 denotes a root aligning plate, and the root aligning plate 22 is rotatably supported at its base end by a bracket 23 supported by the support frame 9 so as to be slidable in the left-right direction, and further provided on the bracket 23. It is urged toward the tip side by the ammunition machine 24 to be held, and the tip end portion is elastically pressed against the locking portion 25 protruding on the binding machine 4 side so that the posture of the predetermined swing angle is maintained. However, the root aligning plate 22 is integrated with the binding machine 4 by integrally connecting the connecting rod 26 and the bracket 23, which extend parallel to the support frame 6 on the binding machine 4 side. It is designed to move left and right.

Further, 27 is a control unit provided in the airframe 1, and the control unit 27 is a microcomputer (CPU, ROM, RAM).
This is a signal from the lever position detection sensor 31 for detecting the lever position of the handling depth adjusting lever 30 for adjusting the position of the handling depth chain 29, the potentiometer 18, etc. Is input, and the drive motor 15 is drive-controlled based on the determination based on the input signal. That is, when the handling depth adjusting lever 30 is operated to the long culm side, the binding machine 4 is driven to move to the root side, and when it is operated to the short culm side, the binding machine 4 is driven to move to the tip side. By controlling the drive of the motor 15, the position of the binding machine 4 is automatically adjusted according to the culm length. However, even if the detection value of the potentiometer 18 is changed by the operation of the adjusting handle 21, Drive motor 15 to set the detected value to a value corresponding to the culm length.
Is driven to move the binding machine 4.

In the embodiment of the present invention configured as described above, in the binding machine 4, the culm is brought into contact with the rooting plate 22 by the forward and reverse drive of the drive motor 15 based on the adjustment position of the handling depth adjustment lever 30. In order to bind them in a state where they are neatly aligned, the movement is controlled to be positioned at an appropriate position corresponding to the culm length. However, as in the case of deep handling in the threshing unit 2, the tips are threshed. When the culm is conveyed in the leading inclined posture on the stocker side so that it does not come out easily from the part 2, the value detected by the potentiometer 18 is corrected by operating the adjustment handle 21 so that the culm stock is removed. The drive motor 15 can be operated to position the binding machine 4 at an appropriate position where the original contacts the root aligning plate 22. Therefore, the binding machine 4 can always be positioned at an appropriate position, and the binding culm that is tied up in order and accurately bound at a predetermined position can be discharged. As a result, the working accuracy in the binding process can be significantly improved. Can be improved.

Moreover, since the binding is performed based on the stock origin, it is possible to surely bind the stock on the stock side which has the best tightness in the culm, and as a result, perform the ideal binding process without dropping the culm. You can Also, if it is necessary to dry after bundling, by bundling the tip side on the basis of the plant origin, the plant side with the most water can be spread and dried to greatly accelerate the drying of the culm. .

The present invention is not limited to the above-mentioned embodiment, and the function of the second embodiment shown in FIGS. 6 and 7 can be added. In other words, this one has the bracket 23 that supports the rooting plate 22,
It is connected to the connecting culm 26 on the binding machine 4 side so as to be movable in the left-right direction, and the fixed handle 32 is screwed into the bracket 23 to enable the angle adjustment (bundling position adjustment) of the root aligning plate 22, while the bracket 23 is a potentiometer 33 attached to the machine body 1 side connected via a detection rod 34, and in this one, the positional deviation of the root aligning plate 22 due to the bundling position adjustment is detected by the potentiometer 33. It can be automatically corrected by moving the binding machine 4 based on the detected value. Further, the detection value of the potentiometer 33 is the binding machine 4
Since it changes depending on the movement of the binding device, it can be used also as the position detecting means of the binding machine 4 like the potentiometer 18 of the above embodiment.

Still further, according to the present invention, as in the third embodiment shown in FIG. 8, the pretreatment section 35 is provided with the tip detection sensor 36 without manually adjusting the handling depth as in the above-mentioned embodiment, and It can also be implemented in a device provided with an automatic handling depth adjusting mechanism for controlling the rotation of the handling depth carrier 37 based on detection. In this case, since the movement control of the binding machine can be performed based on the accurate culm length information, the binding processing accuracy can be further improved.

[Effects] In summary, since the present invention is configured as described above, a binding machine that is movable in the length direction of the transport culm is provided.
By controlling the movement based on the culm length, it is located at an appropriate position corresponding to the culm length.However, as in the case of deep handling in the threshing part, the tips do not easily come out of the threshing part and are discharged. When the culm is conveyed in a tilted posture at the leading side of the stocker side, the binding position caused by the tilt of the culm is corrected by operating the detection value correcting means to correct the detection value of the swing angle detecting means. This means that the binding machine can be moved to position it at the proper position where the error is corrected.
Therefore, it is possible to always place the binding machine at an appropriate position, and to discharge the binding culm that is tied in order and accurately tied at a predetermined position, and as a result, the working accuracy in the binding process is significantly improved. Can be made. Moreover, as the bundling accuracy is improved, it is possible to surely bind the bunches on the stocker side, which has the tightest bundling in the culm, and as a result, the ideal bundling process without dropping the culms can be performed. it can.
