Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a drive device in a bundle collection and discharge device that collects and discharges a plurality of bundles bound and discharged by a binding device.

(b) Prior art Conventionally, as a drive device for a bundle collection and discharge device, an actuating body that engages and disengages from a constantly rotating rotating body is provided oppositely, and the actuating body is engaged with the rotary body to operate the bundle collection and discharging device for discharging. A device designed to do this is already known from JP-A-60-78512 or JP-U-56-107227.

(c) Problems to be solved by the invention The known bundle collecting and discharging device described above maintains the engaged state (by manually operating the actuating body in pressure contact with the rotating body that constantly rotates) for a period necessary for the bundle discharging operation at the time of bundle discharging. The company had to continue to maintain its cracked state.

(d) Means for Solving the Problems The present invention provides a bundle collecting and discharging device on the side of a bundling device, and a rotating body that rotates at all times has an operation that is rotatable and causes the bundle collecting and discharging device to operate for discharging. By arranging the bodies so that they can be engaged and detached, and by providing a separation guide between the forward and return paths of the actuating body, the actuating body can be simply inserted and operated, and once the actuating body is in the engaged state, the separating guide will control the engaged state of the actuating body. The above-mentioned problem is solved by eliminating the operation of continuing to maintain the entering state by guiding the rotating body during the return trip, and by making it possible to guide the operating body in a state where it is separated from the rotating body. By forming the end of the outward path side into a tapered part, and providing a cam surface that separates the actuating body from the rotating body at a portion opposite to the tapered part on the outward path side, when the actuating body converts from the outward path to the homeward path, it can be separated from the rotating body. The bundle collection and discharge device is reliably disengaged, the discharge operation of the bundle collection and discharge device is performed with high precision, and the bundle collection and discharge device is smoothly shifted to the return path.

(E) Effect When a predetermined number of bundles are collected in the bundle collection and discharge device,
When the actuating body of the drive device is engaged with the constantly rotating rotating body by a detection signal of the bundle counting mechanism or by an appropriate means such as manual operation, the separation guide maintains the state in which the actuating body is engaged with the rotating body. During this time, the actuating body rotates together with the rotary body to release the bundle collecting and discharging device, and then, at the end of the forward path, the actuating body is separated from the rotary body by a cam and is moved outward along the tapered part of the separation guide. The moving direction is reliably changed at the tip of the tapered part, and the moving direction is reliably changed to enter the return path and rotate back.

(f) Embodiment An embodiment of the present invention and its related structure will be explained with reference to the drawings. A binder is attached to the front part of a machine body 2 having wheels 1, 1, a cutting blade, a grass cutting body, and a grain culm pulling body 3, 3.

Further, at the outer lower part of the binding device 10 and the cane guide plate 4, a support shaft 11 in the front and rear direction and a grain culm triggering body 3 are provided.
A stock receiver 13 is removably attached with a hanging rod 12 hanging from the top of the
A bundle collecting device consisting of a grain side receiver 15 which is pivotally supported so as to be able to move up and down at the grain culm pulling member 3,
The grain culms that are pulled up by the mower and cut by the cutting blade are transported to the side of the machine by the horizontal conveyor 5 while leaning on the support guide plate 4, and the packer 16 of the binding device 10 collects the harvested and transported grain culms. When the needle 19 is drawn into the part 17 and focused, and when the focused amount reaches a predetermined amount and the door 18 senses it and operates, the needle 19
wraps the string, the knotting section 20 consisting of a bill and a holder knots, and the release arm 21 releases the tied bundle to the side, the stock base rests on the stock receiver 13, and the panicle side leans down. It is supported and guided by a flow guiding guide 4a made of a flexible plate that projects outward from the guide plate 4 and hangs down inside the ear side receiver 15, and on the outside, from the upper part of the grain culm pulling body 3, the frame body 14a At the same time, it detours around the outside of the ear side receiver 15 as shown in FIG. 2, and is guided by a frame body 22 that serves as a guide and a guard, and is received by the ear side receiver 15.

At this time, when the bundle counting mechanism 23 provided above the bundle car 16 and needle 19 of the binding device 10 counts a predetermined number of bundles, it sends a release signal to the spring 4.
Drive clutch 26 via wire 25 with 2
The drive clutch 26 operates the receiver drive mechanism 28 via the wire 27 using power from the axle, so the ear receiver 15 is tilted upward and the collected bundles are gathered in the field. released.

Next, each device will be explained.

() Bundle Counting Mechanism The bundle counting mechanism 23 is screwed onto the upper surface of the clutch case 10a of the bundling device 10, and has a U-shape in side view, and includes a knotter cover 30 whose upper part faces the lower part of the horizontal conveyor 5, and its upper part. A cover 30b having an inverted L shape, a pin 32 rotatably supported on the top plate by a shaft 31, and having a phase difference of 180 degrees,
32, a first link 36 whose one end is integral with the shaft 31 and has a ratchet pawl 35 in the middle, and a first link 36 whose one end is connected to the needle rod 3.
a second link 39 which is loosely fitted to the middle pin 38 of 7 and whose other end is rotatably connected to the other end of the first link 36;
A detection arm 41 is rotatably fitted into a pin 30a on the lower surface of the top plate of the ratchet wheel 33, and rotates when pushed by the pin 32 of the ratchet wheel 33.The tip of the detection arm 41 is attached to a spring 42.
The support arm of the needle 19 is connected to one end of the wire 25, and the base of the support arm of the needle 19 is pivotally supported by a needle support shaft 43, the base is pivotally attached to the needle rod 37, and the tip of the needle rod 37 is connected to the needle crankshaft. 45 crank arm 4
Since the needle 19 is fitted into the crank pin 47 protruding from the converging part 17, when the crank pin 47 is rotated by the one-turn clutch being engaged by the sensing operation of the door 18, the needle 19 enters the knot part 20 through the converging part 17. At the same time, the second link 39 pushes the first link 36, so the ratchet pawl 35 returns and rotates by one tooth of the ratchet wheel 33, which is held by the anti-reverse pawl 44, and then the needle 19 rotates. When returning, rotate the ratchet wheel 33 by one pitch.

If the bundle counting mechanism 23 is of a type that collects five bundles, FIG. From this state, when the needle 19 enters the knot 20 the most to bind and release the fifth bundle, the ratchet pawl 35 returns by one pitch, and then, when the needle 19 moves to the return stroke, Needle rod 3 as shown in c.
7 rotates, the ratchet wheel 33 rotates, and the pin 32 pushes the detection arm 41 to rotate it clockwise, so the wire 25 inputs the release signal as a tensile force to the drive clutch 26, and at the same time An operating arm 49, which rotates together with the first link 36 and is connected to a wire 48 leading to the receiver drive mechanism 28, rotates toward the loosened side.

() Drive Clutch The drive clutch 26 is provided with a clutch case 50 fitted onto an axle 51 as shown in FIGS. Spring 53
A swinging arm 53 that is biased back at point a is attached to the swinging arm 53, and a pawl 54 that is curved along the outer circumference of the gear 52 and that engages and disengages from the teeth of the gear 52 is attached to the swing arm 53. the actuating body 55 and the wire 27 having
An arcuate separation guide 57 is protruded from the middle part of a cam part 56 which is a longitudinally elongated recess provided on the inner surface of the clutch case 50. A roller 58 pivotally supported at the tip of the actuating body 55 is guided to pass between the separation guide 57 and the gear 52 and over the upper part of the separation guide 57, and the left end is formed into a tapered part 57a, and the lower surface is formed from the inner circumference. The cam portion 56 is formed into a slope that gradually moves toward the outer periphery, and a portion of the cam portion 56 facing the lower portion of the tapered portion 57a is formed into a cam surface 56a that protrudes outward while descending.

Further, a fulcrum pin 60 rotatably supported on the clutch case 50 includes a pressing body 61 and the wire 2.
5 is returned and an arm 63 connected via a spring 62 is fixed.

As long as the number of bundles released and collected from the binding device 10 is less than 5 bundles, the bundle counting mechanism 23 does not output any output as shown in FIG. 9, and the wire 25 is relaxed, so that the arm 63 The connecting pin 75 is pushed down by the return spring 62 and comes into contact with the lower part 76, and the pressing body 61 is thereby rotated upward and into the retracted position, and the roller 58 of the actuating body 55
Since the swinging arm 53 is pushed up by the coil spring 53a, it is pressed against the upper right corner of the cam portion 56 and assumes a rising position, and the pawl 54 is disengaged from the gear 52.

However, when the bundle counting mechanism 23 operates to detect the fifth bundle, the wire 25 is pulled, the connecting pin 75 comes into contact with the lower surface of the upper part 77, and the pressing body 61 is activated to detect the fifth bundle.
Since the roller 58 is pushed down as shown in Figure d,
The pawl 54 meshes with the constantly rotating gear 52 and rotates downward as shown in FIG. Perform the release.

When the roller 58 reaches the slope 57a of the separation guide 57, it is pushed outward by the driving force of the gear 52, and the cam surface 56a of the lower part of the cam portion 56 descends while protruding outward. As a result, the roller 58 is pushed out and moves along the lower surface of the tapered part 57a of the separation guide 57, and when the wire 27 is pulled to the maximum, the claw 54 is completely removed in the state shown in FIG. , since the swinging arm 53 is urged upward by the coil spring 53a, the roller 58 is moved upwardly by the separation guide 5.
7 and moves upward beyond the tip of the tapered part 57a,
At this time, since the tying of the sixth bundle, which will be the next collection group, has not yet started, the wire 25 is being pulled and is received by the pressing body 61, which is in the downward position, as shown in FIG. 10a. The actuating body 55 is prevented from rotating downward, the binding of the sixth bundle begins, and the ratchet wheel 33 of the bundle counting mechanism 23 moves to the position shown in FIG. 6c.
When the pin 32 is rotated from the state shown in FIG.
It rotates back due to the pressing force of step 2 and returns to the state shown in FIG.

() Receptor drive mechanism Figures 12 to 16 show the receiver drive mechanism 28 of the ear side receiver 15. The ear side receiver 15 consists of a gutter-shaped receiving part 15a and an arm part 15b. The boss is rotatably supported by a horizontal shaft 14 protruding from the frame 14a, and the receiver drive mechanism 28 is supported by a control pin 66 protruding from the arm portion 15b and a horizontal shaft 14.
stopper pins 67 and 68 fixed to a mounting plate 65 integral with the control pin 66 at upper and lower limit positions; a driver 70 connecting the ends of the wires 27 from the
The stopper lever 71 has a lower part rotatably supported on a mounting plate 65, connects the wire 48 from the actuating arm 49 of the bundle counting mechanism 23, and has a stepped portion 71a.

When the bundles are being collected, the ear side receiver 15 and the receiver drive mechanism 28 are in the state shown in FIG.
3 is detected and actuated, which causes the drive clutch 26 to actuate and the wire 27 to pull the drive element 70 and rotate the ear receiver 15 upward until the control pin 66 abuts the upper stopper 67, so that no waste is collected. All the bundles are released into the field at once.

At that time, the wire 27 connects the ear side receiver 15 to the 15th
As shown in the figure, the driver 70 is pulled down until it comes into contact with the upper stopper 67 and then relaxed, so the driver 70 rotates downward and the ear receiver 15 rotates downward due to its own weight.
The control pin 6 is biased to rotate clockwise by
6, the stepped portion 71a receives the control pin 66 and maintains the release posture of the ear-side receiver 15, as shown in FIG.

However, when the bundle counting mechanism 23 next detects the timing for releasing the bundle, the actuating arm 49 moves upward from the stopped position as the crank arm 46 rotates 90 degrees from the stopped position, as shown in FIG. 6b. Since the stopper lever 71 rotates counterclockwise, the stepped portion 71a comes off from the control pin 66, and the ear receiver 15 descends due to its own weight. The control pin 66 is then received by the lower stopper 68 and assumes the receiving position.

Further, in the process of the return rotation of the needle 19, the actuating arm 49 rotates upward as shown in FIG.
The action returns to the posture shown in FIG. 14.

An actuation system from the drive clutch 26 that raises and rotates the ear receiver 15 to the release position in this way;
Since the actuation system from the bundle counting mechanism 23 for placing in the receiving position is separated and independent, it is possible to easily set the timing for placing the panicle side receiver 15 in the releasing position and the timing for returning it to the receiving position to the optimum state. The timing can be adjusted separately depending on operating conditions such as culm length, bundle size, or number of bundles to be collected.

Furthermore, even after the panicle side receiver 15 is raised to the maximum extent and the bundle is released, the stopper lever 71
Since the ascending position is maintained, the bundle can be discharged more accurately, and just before the next bundle is discharged, it descends and returns to the bundle receiving position.

Reference numeral 73 indicates a hole into which the mounting seat on the horizontal axis is adjusted by moving in the length direction of the frame 14a and is screwed therein, and 80 indicates a bundle slip-off guiding plate.
