JPH0737A - Automatic binding unit for roll bailer - Google Patents

Abstract

PURPOSE:To obtain an automatic binding unit for a roll bailer, which can avoid operation mistake by automation of the work from the completion of bailing to that of binding and increase operational efficiency by shortening operational time. CONSTITUTION:A detection switch (S1) operated by the pressure in a bail forming chamber (1) at the completion of bailing, a driving motor of a rope delivery mechanism (3a), a solenoid switch turning off the detection switch (S1) and a change-over switch (S3) linked to clutching motion of a rope transferring mechanism (3b) are electrically connected with each other. The change-over switch (S3) constructs circuits A and B. By the detection switch (S1) turned on, the driving motor is energized to drive the rope delivery mechanism (3a). Then, a rope (2) is delivered from the rope delivery mechanism (3a) and wound on a bail. This creates tension on the rope and engages the clutch of the rope- transferring mechanism (3b) and at the same time the turn-over switch (S3) actuates to turn over the circuit A to B. This turns the solenoid switch on and the detection switch (S1) off.

[0003]

As described above, in the prior art, the work process from the completion of the bale of a certain size in the bale forming chamber to the completion of the binding by the string winding is as follows. Manual operation of the work clutch lever,
It is inefficient due to work mistakes due to operation timing. Therefore, the present invention, as described above, uses the conventional roll base.

[0004]

SUMMARY OF THE INVENTION In order to achieve the object described above, the present invention provides a bale forming chamber, a string feeding mechanism and a string traverse mechanism for winding a string around the bale. In a roll baler configured with a bundling device including a bundling device and a discharging mechanism for taking out the bale after bundling, sensing is performed by the completed bale pressure formed in the bale forming chamber. The switch, the drive motor of the string feeding mechanism, and the sensing switch are turned on.
A solenoid switch for FF and a changeover switch interlocking with the clutch operation of the string transverse feed mechanism are electrically connected, and the changeover switch forms an A circuit and a B circuit. When the sensing switch is turned on, a drive motor is driven. Is energized to drive the cord feeding mechanism, and the tension of the cord caused by the cord being wound around the bale causes the clutch of the cord transverse feed mechanism to be “engaged” and at the same time the circuit A to the circuit B is operated by the changeover switch. It is characterized in that the solenoid switch is turned on and the sensing switch is turned off.

[0005]

With this structure, when the bale formed in the bale forming chamber is completed, the sensing switch senses this and turns on the switch to drive the string feeding mechanism constituting the bundling device. The power is supplied to the cable to drive the string feeding mechanism to feed the string. When the unwound string is wound around the outer circumference of the rotating bale, the string gains tension, and the tension of the string causes the clutch of the string traverse mechanism to "engage" to start traverse of the string. The solenoid switch is turned on and the sensing switch is turned off by the electromagnetic action to stop the rotation of the drive motor because the changeover switch changes the circuit A to the circuit B in conjunction with this clutch operation. Then, when the binding is completed by the lateral feed of the cord, the cord is cut by the cutter and loses the tension, whereby the clutch of the cord lateral feed mechanism is turned off and the lateral feed of the cord is stopped. After switching to the A circuit, the original state is restored and the operation for bale forming and bundling is started.
