Description

[Detailed Description of the Invention] (A) Field of Industrial Application The present invention relates to 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, bundle collection and discharge devices have been equipped with a detection mechanism that detects the collection of multiple bundles, and in response to the detection signal, the operator manually engages the clutch of the discharge drive device and maintains the engaged state. This method is already known from Japanese Unexamined Patent Publication No. 60-78512 or Japanese Utility Model Application No. 56-107227.

(c) Problems to be solved by the invention In the known bundle collecting and discharging device, the clutch must be kept in the engaged state by manual operation for the period necessary for the bundle discharging operation at the time of bundle discharging, and the clutch must be kept in the engaged state by manual operation. ,
As I had to turn on and off, the timing of the release operation of the panicle side receptor may be too early or delayed, and if it is too early, the panicle side receptor may return and release before the release is completed. There were problems such as some of the bundles to be taken out getting caught in the bundle collecting and discharging device, and if it was too slow, the first bundle in the next process could not be collected.

(d) Means for solving the problem The present invention is equipped with a bundle collecting and discharging device on the side of the bundling device, which consists of a stock receiver and a panicle side receiver that rotates downward by its own weight around a horizontal axis. , the above panicle side receptor,
A drive device that works with a one-turn clutch is connected to the drive device so as to rotate upward and release the bundles when a predetermined number of bundles have been collected. When the body rotates upward and assumes the discharge position, the control pin engages and pivots a stopper lever that supports the ear receiver, and the stopper lever is connected to the drive device when the bundle discharge is completed. The above-mentioned problem has been solved by interlocking and interlocking so that the retracting operation causes the ear-side receiver to rotate downward to take the bundle-receiving position.

(E) Effect When a predetermined number of bundles are collected in the bundle collection and discharge device,
The bundle collecting and discharging device operates in conjunction with the shaft that rotates when the one-turn clutch is engaged. However, after the bundle collecting and discharging device discharges, it returns to the bundle receiving position immediately before the binding device collects and releases the next bundle of grain culms, so it can ensure that all the collected bundles are released and To surely catch the first bundle to be released in the next process.

(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.

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 transport body 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 which is rotatably fitted into a pin 30a on the lower surface of the top plate and rotates by being pushed by the pin 32 of the ratchet wheel 33; It is composed of a link 36 and an actuation arm 49 that rotates together, and the tip of the detection arm 41 is connected to one end of the wire 25 having a spring 42.
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 distal end of the needle rod 37 is attached to a crank pin 47 protruding from the crank arm 46 of the needle crankshaft 45. When the crank pin 47 is rotated by the detection operation of the door 18, the needle 19 enters the knot part 20 through the converging part 17, and at the same time engages the knot. 2nd link 39
presses the first link 36, so the ratchet pawl 35
is rotated back by one tooth of the ratchet wheel 33, which is received by the anti-reverse pawl 44, and then when the needle 19 returns, the ratchet wheel 33 is rotated 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 to bind and release the fifth bundle as shown in FIG. As shown, the ratchet wheel 33 rotates as the needle rod 37 rotates.
As the pin 32 pushes the detection arm 41 to rotate it clockwise, the wire 25 inputs the ejection signal as a tensile force to the drive clutch 26, and at the same time the actuation arm 49 rotates the needle 19 from the rest state of FIG. 6a. During the 90 degrees leading to top dead center, the receiver drive mechanism 2
8, the wire 48 is further relaxed as shown in FIG. It comes off from 71a, returns to the state shown in Fig. 7a via d, and stops.

() 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 4 or less, the latch wheel 33 only rotates one pitch at a time, and the pin 32 does not push the detection arm 41. As shown in Fig. 9, the bundle counting mechanism 23 does not output any output, and the wire 25
is relaxed, and the arm 63 returns to the spring 6.
2, the connecting pin 75 is pushed down by the lower part 7.
6, thereby causing the pressing body 61 to rotate upward and take a retracted position, and the roller 58 of the actuating body 55 is moved by the coil spring 53a to the swinging arm 53.
is pushed up, so it is pressed against the upper right corner of the cam part 56 and is in a rising position, and the claw 54
has separated 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 tapered part 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 part 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. At this time, since the binding of the sixth bundle, which will be the next collection group, has not started, the wire 25 is being pulled, and the first
As shown in FIG.
When rotated from the state shown in FIG. d, the pin 32 fits into the notch 41a of the detection arm 41 and the wire 25
is relaxed, and as a result, the pressing body 61 is rotated back by the pressing force of the return spring 62, returning to the state shown in FIG.

() Receiver 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 projecting from the frame 14a, and the receiver drive mechanism 28 is supported by a control pin 66 projecting from the arm portion 15b and a horizontal shaft 14.
stopper pins 67 and 68 that are fixed to a mounting plate 65 integral with the drive clutch 26 and that receive the control pin 66 at the 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 driver 70 and rotate the ear receiver 15 upward until the control pin 66 abuts the upper stopper pin 67. 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 element 70 is pulled downward until it comes into contact with the upper stopper pin 67 and then relaxed.
2, and just before the release arm 21 completes the release of the bundle, the actuating arm 49 of the bundle counting mechanism 23 returns and the wire 4
8 is relaxed, the stopper lever 71 enters the rotation locus of the control pin 66, and as shown in FIG. The releasing posture of the body 15 is maintained.

However, when the tying device engages the single rotation clutch to tie the sixth bundle, i.e. the first bundle of the next collection group, the needle 19 begins to enter the knot and the discharge arm 21 pivots back. Initially, the second link 39 starts from the state shown in FIG. 6a and moves to the left, and the operating arm 49 moves to the slack side while the crank arm 46 rotates 90 degrees from the stop position as shown in FIG. 6b. Although the pin 38 of the needle rod 37 moves along the rotation path A toward the position shown in FIG. When the position shown in FIG.
comes off from the stepped portion 71a (needle crankshaft 4
5 has been rotated approximately 180 degrees (see FIG. 7), the panicle-side receiver 15 is lowered into a receiving position, and during this time the knotting portion operates to knot as shown in FIG.

Next, the release arm 21 discharges the bundle, and the stock end of the released bundle is received by the stock receiver 13, and the ear side is received by the panicle side receiver 15 which is in the downward position. In the process of returning and rotating, the wire 48 is relaxed by returning from the state shown in FIG. 6 d to the state shown in FIG.
Return to the position shown in the figure.

After releasing the bundles collected in this way, the timing at which the ear side receiver 15 returns to the receiving position is delayed from the start of tying the next bundle (when the one-turn clutch is engaged). Even if the ears of grain culms released from the grain culm are entangled with other members, they can be completely discharged, and the ear receiver can be returned to the receiving position without delay when the next bundle collection starts. .

Reference numeral 73 designates a hole into which the mounting seat of the horizontal shaft 14 is adjusted by moving in the length direction of the frame 14a and is screwed therein, and 80 is a bundle sliding guide plate.

(g) Effects of the invention As described above, the present invention provides a bundle collecting and discharging device which is provided on the side of the bundling device 10 and includes a stock receiver 13 and a panicle side receiver 15 that rotates downward by its own weight around a horizontal axis. The panicle-side receiver 15 is connected to a drive device that works with a one-turn clutch so that it rotates upward and releases the bundles when a predetermined number of bundles are collected. A pin 66 is provided on the support portion, and the control pin 66 engages with the control pin 66 to pivotally support a stopper lever 71 that supports the ear side receiver 15 when the ear side receiver 15 rotates upward and assumes the release position. The stopper lever 71 is interlocked with the drive device so that when the bundle release is finished, it is retracted and the panicle-side receiver 15 is rotated downward to take the bundle receiving position, so that the collected bundles are kept in a predetermined position. When the number of bundles is reached, the panicle-side receiver 15 automatically rotates upward about the horizontal axis to discharge the collected bundles almost simultaneously, and can be discharged to the field in a well-aligned state.

Furthermore, when the panicle-side receiver 15 rotates upward and assumes the releasing position during the above-mentioned bundle release, the regulating pin 66 is received by the stopper lever 71 to maintain the releasing position, thereby reducing the need for artificial operating force. The ear side can be completely released without needing to be used, and after this release, the stopper lever 71 is moved in conjunction with the drive device.
is retracted, which causes the restriction pin 66 to come off.
The panicle side receiver 15 can be quickly and easily rotated downward to the bundle receiving position by its own weight, thereby reliably preventing bundle receiving errors.
