Description

Detailed Description of the Invention "Industrial Application Field" The present invention picks up vines such as grass and straw scattered in a field with a pick-up section and forms them into a roll-shaped bale in a bale-forming chamber. The present invention relates to a roll baler that is bound by twines supplied from a binding device.

"Prior Art" Conventionally, in Utility Model Application No. 80-23351, etc., a technology has been developed in which the runner is moved left and right when feeding out the twine.

``Problems to be Solved by the Invention'' In the conventional technology, the bale winding operation of the twine and the runner cross-feeding operation are performed at the same time, so there is a problem that the runner moves before the twine is wrapped around the bale. There were problems such as the twine winding becoming unstable.

"Means for Solving the Problems" However, the present invention provides an apparatus in which a runner for guiding and holding twines is supported so as to be able to reciprocate from side to side, and the twines are wound around the outer periphery of the bale by the left and right movement of the runner. An actuating member is disposed between the bail and a string brake that lets out the twine at a tension higher than a set tension, and the actuating member is displaced by the tension of the twine wrapped around the bale to drive the runner drive member.

``Function'' Therefore, the runner can be moved after the twine is wrapped around the bale, and the twine is not fed sideways unless the twine is wrapped around the bale, so the twine can be rolled more stably and reliably than in the past. The bale can be easily wrapped around the bale, preventing the bale from losing its shape, and making it easier to transport and store the bale than in the past.

The twine (
7th) At the same time as inserting the tip, insert the conveyor (17th
), the hay is supplied and guided by a fixed guide plate (101), and the rectifying action of this guide plate (101) distributes the uneven hay evenly to the left and right sides of the conveyor (17).

Further, the tip of the twine (78) is wrapped around the bale (A), and the twine (78) is pulled out by the rotation of the bale (A), so that the roll (73) is idly rotated at a higher speed than this driving speed. and the twine (78)
The twine guide plate (8B) is pushed up by the tension that pulls out the clutch arm (99) and shift fork (98).
The tying clutch (69) is turned on via the twine moving chain (65) to move the runner (90) left and right to wrap the twine (7 days) on the left and right sides of the bale (A). It consists of

As shown in FIG. 8, when the runner (90) reaches the end of left and right movement, the eight locking pins (8
8)... are in continuous contact with the edge of the engagement hole (88) of the runner (90), and the runner (80) is stopped and held at this end of left and right movement, and the twine (78) is attached to the left and right ends of the bail (A). It is configured so that it is wound overlappingly.

Further, as shown in FIG.
), the twine (78) comes into sliding contact with the back of the cutter (85), and this twine (7th) causes the spring (103) to move forward.
While retracting the cutter (85) against the

) is configured so that it is caught and cut.

Furthermore, one end of the twine guide plate (8B) is attached to the side plate (3a) by a support arm (104), and the guide plate (86) is held downward by a spring (105). ) is provided with a normally closed bundling switch (10B) that detects the movement of the bale (A). As shown in Figure 10, when the bale (A) is formed, this pressure causes the upper pipe conveyor (16) to move to the lower pipe conveyor (
17) via a normally open bail switch (107) that detects separation from the bail switch (107) and the bundling switch (10B),
The buzzer (108) and lamp (109) are connected to this power source (1
10) and activate the buzzer (108) and lamp (109) when the veil (A) is formed.

At this time, by operating the handle (82), the twine (78)
When the twine (78) is wound around the bale (A), the buzzer (10B) and the lamp (109) are turned off, and furthermore, the twine (78) has been wrapped around the bale (A) and the twine (78) is wrapped around the bale (A). 78) is disconnected, the buzzer (10
8) and the lamp (109) are activated again, opening the door (36) and removing the bale (A).

Further, as shown in Fig. 1, the hanging plate (1) is attached to the front end of the pickup guide plate (5) so as to be able to swing back and forth via the support shaft (111).
12) is suspended to improve the hay taking-in performance by the pick-up finger (35).

The present embodiment is constructed as described above, and the hay picked up by the pickup section (0) is carried into the bale forming chamber (18) by the lower pipe conveyor (17), and the hay is carried into the bale forming chamber (18) by the upper and lower pipe conveyor (1B) (17). ) to form a roll-shaped veil (A).

Now, when the diameter of the bale (A) is larger than a predetermined diameter, the upper pipe conveyor (16) is pushed upward by the bale (A) pressure and the switch (107) is turned on. , a buzzer (108) and a lamp (109) are driven to notify the operator of the completion of veil (A) formation.

Then, the running latch lever (13) is turned off, and the roll closing handle (82) is operated to let out the twine (78), so that the tip of the twine (78) reaches the bail (A).
) and is pulled around the binding clutch (69
) is turned on, and the twine (78) starts binding, and the runner (90), which is now located at the approximate center of the binding case (80), is driven by the checker 7 (65) to move toward the arrow ( As shown in the L) direction, the veil (A)
The twine (78) fed out from the rolls (73) (79) on the outer periphery is passed through the guide (91) to (1) to (1) in Fig. 11.
As shown in (5), when the runner (90) reaches the end of left-right movement and turns back, eight locking pins (
88)... stops the movement of the runner (9o) while it is in contact with one end edge (89a) or (89b) of the engagement hole (89), and the twine (78) at both ends of the veil (A) ) is wound multiple times in order to prevent the formation of the veil (A) from being delayed.

“Effects of the Invention” As is clear from the above examples, the present invention
In the apparatus, a runner (90) for guiding and holding a bale (A) is supported so as to be able to reciprocate from side to side, and a twine (78) is wound around the outer periphery of a bale (A) by moving the runner (90) from side to side. ) is disposed between the bail (A) and a string brake such as a clutch body (96) that pays out at a tension higher than the set tension, and an actuating member such as a twine guide plate (8B) is disposed.
The operating member (86) is displaced by the tension of the twine (7 days) wrapped around the bale (A), and the runner moving chain (6) is moved.
5) etc., the runner (90) can be moved after the twine (78) is always wrapped around the bale (A), and the runner (90) can be moved.
Unless twine (78) is wrapped around A), twine (7
Since there is no horizontal feeding of the twine (78), it is possible to wrap the twine (78) around the bale (A) more stably and reliably than before, preventing the bale (A) from losing its shape, etc., and making the bale (78) easier than before. This has the advantage of being able to carry out the transportation and storage described in A).
