In the removal portion 5, the line connecting the axes of the pair of removal rolls 3 and 4 is inclined by about 30 ° from the horizontal (in FIG. 1, the removal roll 4 is arranged above the removal roll 3). The depletion rolls 3 and 4 are arranged diagonally, the peripheral speeds of the depletion rolls 3 and 4 are different from each other, and the rolls 3 and 4 are rotated in opposite directions to supply paddy to the gaps t of the depletion rolls 3 and 4. It is a form (roll type rice husk machine) in which rice husks are sheared and broken due to the difference in peripheral speed between them.

The paddy supply unit 8 vibrates the vibrating trough 12 by the vibrating mechanism 11 of the vibrating feeder 7 with the paddy stretched from the input port 10 of the paddy hopper 6 to generate an appropriate amount of paddy evenly and in parallel from the trough tip. It has the effect of sending. The vibration trough 12 is appropriately provided with a flow rate adjusting plate 13, and the amount of paddy fed can be adjusted or regulated. Reference numeral 14 is a raw material presence / absence sensor attached to the paddy hopper 6, and the drive of the paddy machine can be controlled to be turned on / off by the detection of the sensor.

The width of the slipstream plate 15 is set to be substantially the same as the width of the removal rolls 3 and 4, which is 25.4 cm if the width is 10 inches. Then, if the slide plate 15 is arranged so that the virtual line extending in the length direction thereof and the line connecting the centers of the removal rolls 3 and 4 intersect substantially vertically, the removal rolls 3 and 4 are formed. When the paddy is supplied, the paddy is less likely to be repelled and the posture is disturbed, and the generation of crushed particles at the time of removal can be suppressed.

FIG. 2 is a schematic view showing a first drive system of a removal roll drive unit on the back side of the paddy machine 1. The machine frame 2 of the paddy machine 1 is provided with a first drive motor 17 arranged on the side surface portion of the machine frame 2 and a second drive motor 18 arranged on the upper part of the machine frame 2.

Further, a movable movable idler pulley 31 that serves as a tension for tensioning the belt is provided on the side of the de-roll 4. The second drive system is formed by these plurality of pulleys, and the endless belt 26 is wound between the motor pulley 30, the large diameter pulley 27, the small diameter pulley 28, and the movable idler pulley 31. At this time, since the first drive system and the second drive system are not driven at the same time, the endless belt 26 used in the first drive system is temporarily removed and used in the second drive system (shared). ) Is preferable.

In FIGS. 2 and 3, the movable idler pulley 25 of the first drive system is configured to be rotatable around the fulcrum 33 to the position of the alternate long and short dash line (reference numeral 25a) by contraction of the air cylinder 32. Similarly, the movable idler pulley 31 of the second drive system is also configured to be rotatable around the fulcrum 35 to the position of the alternate long and short dash line (reference numeral 31a) by extending the air cylinder 34.

Then, a limit switch 36 as a position detecting means of the movable idler pulley 25 is provided at an appropriate position of the machine frame 2, and a limit switch 37 as a position detecting means of the movable idler pulley 31 is provided. The position detection means is not limited to this, and for example, the position detection means may be substituted by detecting the air pressure of the air cylinders 32 and 34. That is, by detecting the air pressure, the presence or absence of driving of the air cylinders 32 and 34 can be detected, and the positions of the movable idler pulleys 25 and 31 can be indirectly known.
In FIGS. 2 and 3, the roll shaft 21 of the de-roll 3 is fixed, and the roll shaft 19 of the de-roll 4 is rotatable around the fulcrum 46. Then, the de-roll 3 and the de-roll 4 can be brought into contact with each other so that the gap t becomes almost zero due to the contraction of the air cylinder 47.

FIG. 4 is a control block diagram of the paddy machine of the present invention. Referring to FIG. 4, the paddy machine 1 of the present invention is provided with a control panel 38 that receives signals from various sensors and sends commands to various actuators. On the input side of the control panel 38, a timer 39 for measuring the timing of alternately switching the high-speed side of the de-roll to the low-speed side and the low-speed side to the high-speed side, and a roll wear sensor 43 composed of a camera or the like, and three. A power switch 40 that connects and disconnects a phase 400V or three-phase 200V power supply, a stop switch 41 that stops the rotational drive of the depletion roll, a drive switch 42 that rotationally drives the depletion roll, and the movable idler pulley. The limit switches 36 and 37 for detecting the position, the belt change completion button 48 for notifying the completion of the belt change by the operator, and the raw material presence / absence sensor 14 are electrically connected to each other.

On the other hand, on the output side of the control panel 38, the first drive motor 17, the air cylinder 32, and the display unit 44 (the high-speed side of the de-roll is on the low-speed side and the low-speed side of the de-roll is for the operator). The side is instructed to switch to the high-speed side.), The second drive motor 18, the air cylinder 34, the feeder coil 45, and the air cylinder 47 are electrically connected to each other.

Next, the control contents of the control panel 38 will be described.
FIG. 5 is a flowchart showing a control content when the high-speed side of the de-roll is switched to the low-speed side and the low-speed side is alternately switched to the high-speed side.
As a tentative, first, the endless belt 26 is wound around the first drive system shown in FIG. 2, the power is turned on to the paddy machine 1, and the first motor 17 is started (not limited to this, shown in FIG. 3). It may be started from the second drive system.) As a result, rotation is transmitted from the motor 17 to the first large-diameter pulley 22, the first small-diameter pulley 20, and the movable idler pulley 25, the depletion roll 3 rotates at a low speed, and the depletion roll 4 rotates at a high speed. Rotate inward to each other. Subsequently, the feeder coil 45 of the vibration feeder 7 is energized, and the raw material paddy sent from the charging port 10 is dropped into the slip plate 15 of the guide chute portion 9 in a band shape.

Then, the paddy that has fallen on the sliding plate 15 slides down in a strip-like thin layer, and is thrown into the gap between the de-rolls 3 and 4. The introduced paddy is deprived by the depleting rolls 3 and 4, and the rice husks are peeled off from the paddy (step 1).

In this way, when the de-pulling process is continued in the first drive system, the de-pulling rolls 3 and 4 are gradually worn. Here, the depleting roll 4 rotating at high speed wears earlier than the depleting roll 3 rotating at low speed. Here, when the outer diameter becomes smaller due to the wear of the de-rolls 4, the difference in peripheral speed between the de-rolls 3 and 4 decreases, and the de-pulling action becomes inferior. Therefore, in the vicinity of the removal rolls 3 and 4, a roll wear (detection) sensor 43 by a camera or the like (such a roll wear sensor is a camera or the like, as well as a contact sensor shown in paragraph 0027 of JP-A-10-33997. , The photoelectric sensor shown in paragraph 0019 of Japanese Patent Application Laid-Open No. 9-313959 may be provided.). In addition, a timer 39 or the like may be provided to estimate the degree of wear. Then, the removal process is performed by switching from the first drive system to the second drive system based on the measured value information of the wear degree from the roll wear sensor 43 and the estimated value of the wear degree based on the elapsed time of the predetermined time by the timer-39. Will be done.

That is, the vibration feeder 7 and the first motor 17 are stopped to stop the first drive system (step 2). Next, with respect to the first drive system (or the second drive system) that was started in step 1, it is verified whether the de-roll 3 on the fixed side has a high-speed rotation or a low-speed rotation (step 3).

In the first drive system, the depletion roll 3 on the fixed side rotates at a low speed, and the depletion roll 4 on the moving side rotates at a high speed. Therefore, steps 3 to step 4 are reached along the No arrow. .. In step 4, the display unit 44 is instructed by the control panel 38 to display "Change the belt from the first drive system to the second drive system", and instruct the operator to change the belt. Next, in step 5, the work of extending the air cylinder 32 to loosen the tension of the endless belt 26 is performed, and in step 6, the operator manually drives the endless belt 26 from the first drive system to the second drive system. Work to switch to the system is performed.

Then, when the work of changing the endless belt 26 from the first drive system to the second drive system is completed, the operator himself presses the belt change completion button 48 (see FIG. 4). Next, in step 7, the air cylinder 34 is extended to stretch the belt. Along with this, the movable idler pulley 31 is moved to the vicinity of the reference numeral 31a to stretch the endless belt 26, and the limit switch 37 is also turned on by the movement of the movable idler pulley 31. When the limit switch 37 is turned on, it can be confirmed that the tension of the endless belt 26 is appropriate, and the movable idler pulley 31 of the second drive motor 18 is appropriate by the electric signal of the limit switch 37. Since it is a mechanism (interlock) that can be driven only in the correct position, there is an advantage that safety confirmation can be performed automatically.
After the limit switch 37 is in the ON state, the second drive motor 18 is driven in step 9 and the padding is restarted (step 10).

On the other hand, in step 3, when the depletion roll 3 on the fixed side is rotating at high speed and the depletion roll 4 on the moving side is rotating at low speed (in the case of the second drive system), Yes in step 3. Follow the arrow to reach step 11. In step 11, the display unit 44 is instructed by the control panel 38 to display "Change the belt from the second drive system to the first drive system", and instruct the operator to change the belt. Next, in step 12, the work of contracting the air cylinder 34 to loosen the tension of the endless belt 26 is performed, and in step 13, the endless belt 26 is manually driven by the operator from the second drive system to the first drive. Work to switch to the system is performed.

Then, when the work of changing the endless belt 26 from the second drive system to the first drive system is completed, the operator himself presses the belt change completion button 48 (see FIG. 4). Next, in step 14, the work of contracting the air cylinder 32 and stretching the belt is performed. Along with this, the movable idler pulley 25 is moved to the vicinity of the reference numeral 25a to stretch the endless belt 26, and the limit switch 36 is also turned on by the movement of the movable idler pulley 25. When the limit switch 36 is turned on, it can be confirmed that the tension of the endless belt 26 is appropriate, and the first drive motor 17 has an appropriate movable idler pulley 25 by the electric signal of the limit switch 36. Since it is a mechanism (interlock) that can be driven only in the correct position, there is an advantage that safety confirmation can be performed automatically.
After the limit switch 36 is in the ON state, in step 16, the first drive motor 17 is driven and padding is restarted (step 17).

As described above, the removal process is performed while switching from the first drive system to the second drive system or from the second drive system to the first drive system, and in step 18, it is determined whether or not the padding work is completed. .. If the amount of wear of the removal rolls 3 and 4 has not reached the limit, the process returns to step 1 along the No arrow. On the other hand, when the amount of wear of the depleting rolls 3 and 4 reaches the limit, step 19 is reached, the paddying work is once completed, the depleting rolls 3 and 4 are replaced with new ones, and then the operation is restarted. Good.

As described above, by performing the de-pulling process while switching from the first drive system to the second drive system or from the second drive system to the first drive system, until the wear amount of the set of de-rolls reaches the limit. It is possible to continue the removal without making a transfer.

Then, according to the present embodiment, a predetermined amount of roll wear degree is detected by the roll wear degree detecting means 43 for detecting the roll wear degree of the pair of removing rolls 3 and 4 and the roll wear degree detecting means 43. When this happens, the padding work is temporarily stopped, and the control means for instructing the operator to change the endless belt 26 from the first drive system to the second drive system or from the second drive system to the first drive system. Since 38 and 38 are provided, when a predetermined amount of roll wear degree is detected on the removal rolls 3 and 4, the first drive system to the second drive system or the second drive system to the first The operator can perform the work of replacing the endless belt 26 on the drive system in a timely manner.

That is, the conventional transmission motor is adopted, a control panel with a timer is provided, a clutch for transmitting the rotational force is provided on the rotating shaft, and a tension clutch for transmitting the rotational force is provided on the pulley. It is no longer necessary to use expensive parts, and it has become possible to provide a padding machine that can alternately switch the high-speed side of the de-rolling roll to the low-speed side and the low-speed side to the high-speed side at low cost. ..
