Description

[Detailed Description of the Invention] The present invention relates to a focusing control device for a reaping and tying machine. In other words, when a gathering device is attached to a reaping and tying machine etc., if a group of bundles forms to a certain extent,
Previously, the operator manually operated a lever to release a group of bundles, but the device of this invention senses the number of bundles and automatically releases the group of bundles when a certain number of bundles has gathered. It is devised so that the number of sets of bundles can be selected arbitrarily while releasing the bundles.

Hereinafter, the present invention will be explained based on the drawings of embodiments of the device of the present invention. Fig. 1 shows a focusing device B equipped with a focusing control device A according to the present invention extended to the side of a tying machine D of a reaping and tying machine C, and a focusing arm 2 rotatably protruding from its underframe 1. , a foot sweep rod 3 is extended toward the rear, and a focusing control device A is housed inside the underframe 1, as shown in FIGS. 2 and 3. FIG. 2 and FIG. 3 will be explained. Binding machine D
4 is a door clutch, and a packer 5 collects the cut stem culms toward the door clutch 4. When a certain state of collection is achieved, the door clutch 4 operates, and the needle 6 and the tubercle are collected. 7. Activate the release arm 8, etc., and release the bundle 9...
is made and released to the focusing arm 2 side of focusing device B,
At this time, the base of the needle 6 and the focusing control device A are connected by a rod 10. The focusing control device A fixes the center of the ratchet gear 12 to the rotating shaft 11, cuts teeth 13 on the outer periphery of the ratchet gear 12, and cuts the teeth 13 and the spindle 14 at the end of the rod 10.
The arm 1 has one end pivotally supported on the rotating shaft 11 while the ratchet pawl 15 is engaged with the ratchet pawl 15 which is pivotally fixed to the arm 1, and the ratchet pawl 15 is pressed by the spring 16.
At 7, the ratchet pawl 15 is configured to rotate around the outer periphery of the ratchet gear 12, and the stop pawl 18 is configured so that the ratchet pawl 15 can be rotated by 13 minutes per tooth of the ratchet gear 12 and stopped when the needle b makes one rotation.
are always pressed into engagement with the teeth 13 by a spring 19. Further, the center cores of disks 20a, 20b, 20c, and 20d are attached and fixed to the rotating shaft 11 at appropriate intervals, and the disks 20a, 20b, 20c, and
A notch 22 is provided on the outer periphery of the disc 20d so that the tip of the claw body 21 enters and the posture of the claw body 21 changes.
a, 20b, 20c, and 20d are divided. That is, the disc 20a is connected to the ratchet gear 1 in FIG.
As shown in combination with 2, the cutout 22
and the notch 22, the teeth 13 of the ratchet gear 12 have 8 teeth as shown by solid lines in the drawing.
Since there are 8 bundles, the needle 6 operates 8 times and the claw body 21 enters the next notch 22 and changes its posture, so the convergence becomes 8 bundles 9, and the combination in the case of Fig. 5 is a circle. There are six teeth 13... of the ratchet gear 12 between the pitches of the cutout 221 of the plate 20b, and in FIG. 6, there are five teeth 13... between the pitches of the cutout 22.
FIG. 7 shows that there are four teeth 13 between one pitch of the notch 22.
Discs 20a, 20b, 20c,
20d are arranged sequentially by type. As described above, one end of the claw body 21 is slidably and rotatably pushed through the support shaft 23 in the axial direction so that the posture can be changed by entering the notch part 22.
The other end is interlocked and connected to the end of the actuating arm 25 of the one-turn clutch 24 by a connecting rod 26,
The connecting shaft 27 between the pawl body 21 and the connect rod 26 is formed long so that the pawl body 21 can slide, and the disc 20 of the pawl body 21 is located at a suitable intermediate position of the pawl body 27.
A, 20b, 20c, and 20d are fixedly provided with a sliding lever arm 28 for selection, the tip of which protrudes outside the underframe 1 and can be operated from the outside, while the one-turn clutch 24 is a focusing arm. It is attached to the base of the arm shaft 29 of 2, and the arm shaft 29
A constantly rotating sprocket 30 attached to the bottom end
The movement of the actuating arm 25 causes one rotation in one cycle.
It is configured to transmit power to the arm shaft 29 for rotation, and other parts are stopped and fixed, so that the bundles 9 can be collected on the focusing arm 2. In the figure, 31 is a tension spring for the operating arm 25, and 32 is a chain for driving the sprocket 30.

The operation of the focusing control device A will now be described with reference to FIG. When the needle 6 of the binding machine D rotates in the direction of arrow A and enters the knotting state at the knotting section 7,
The movement of the needle 6 pulls the rod 10, and with this movement, the arm 17 rotates in the direction of arrow B, engages the ratchet pawl 15, and closes the ratchet gear 12 and discs 20a, 20b, 20c, 20.
Rotate d in the direction of arrow C. This rotation amount is equivalent to the movement of one tooth 13 of the ratchet gear 12 by the arm 17, so the stop pawl 18 moves by one tooth 13 of the ratchet gear 12.
3 prevents the ratchet gear 12 from reversing. Next, the tip of the claw body 21 approaches the notch 22 of the disc 20a due to the rotation of the disc 20a, and eventually enters the notch 22, so the claw body 21 rotates in the direction of arrow N and takes its position. Make changes. In conjunction with the movement of the claw body 21, the actuating arm 25 is pulled in the direction of the arrow H, and the one-turn clutch 4 enters the input state, transmitting the rotation of the sprocket 30 to the arm shaft 29, and moving the focusing arm 2 in the direction of the arrow. make a large turn, release a group of bundles 9, and move 1 to the starting position.
It rotates and stops.

Next, from the disk 20a to 20b, 20c, 20d
3, the tip of the lever arm 28 should be slid in the direction of the arrow T, and the position of the 9 bundles desired to be collected, that is, from FIG. 4 to 7. It is sufficient to stop at the desired position of the combinations shown in the figure.

In this manner, the device of the present invention has the above-mentioned rotating shaft 11 of the ratchet gear 12 which rotates by 1 tooth 13 units for each bundle 9 in conjunction with the binding member such as the needle 6 or the discharge arm 8 of the binding machine D. Several types of discs 2 each having a notch 22 for each set of teeth 13...
0a, 20b, 20c,... are fixed, and the disk 20
a, 20b, 20c, . . . , and the claw body 21 selectively contacts one of the notches 22 . Since the actuating arm 25 of the one-turn clutch 24 which performs intermittent power is interlocked, when a certain number of bundles 9 are gathered in the concentrator B, the ratchet gear 12 and the discs 20a, 20b,
20c... can be automatically sensed and the focusing arm 2 can surely enter the releasing action, and furthermore, the claw body 21 and the discs 20a, 20
It has a feature that the number of bundles 9... to be assembled can be changed and selected by selectively combining any one of b, 20c....
