Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting apparatus for long green onions having roots at the ends of long stems.

[0002]

2. Description of the Related Art Long green onions cultivated and harvested in fields or the like are harvested, and after the roots are cut off, peeling work is performed.
It is shipped after adjusting the length. By the way, in order to carry out this peeling work smoothly, the state of root cutting largely acts. If the root is cut short, the hard part of the root remains and the peeling work takes time, resulting in inefficiency. If the root is cut too much, the commercial value will be reduced. Therefore,
It is desirable that the portion to be cut has an appropriate length as long as possible so as not to be cut too much or cut and left in the onion.

There are cases where workers perform such cutting work, but these works are monotonous work, and when they are performed, work efficiency is not good. Therefore, in recent years, a cutting device has been developed which cuts the cut portion of the long green onion. In the conventional cutting apparatus of this kind of long green onion, the cutting portion such as the root is cut into a certain length.

[0004]

However, since the long green onion cultivated in fields and the like is a natural product, the length of the cut portion such as the root is also irregular. For this reason, in the conventional cutting device, the cutting part such as the root may be cut too much, or the cutting length may be too short and the cutting part may remain in the long onion after cutting.

Therefore, an object of the present invention is to provide a long green onion cutting apparatus capable of reliably cutting only a long green onion cutting portion.

The invention according to claim 1 of the present invention, which has solved the above-mentioned problems, has a cutting means for cutting the onion to be cut, and a light projecting means for projecting light on the onion. A light receiving unit that detects the amount of light projected from the light projecting unit and is emitted through the peripheral surface and the axial cross section of the onion, and one of the light projecting unit and the light receiving unit is provided. It is arranged at one of the outer position of the peripheral surface of the long green onion and the position facing the axial cross section of the long green onion, and the other of the light projecting means and the light receiving means is the outer position of the peripheral surface of the long green onion. And the position of the onion, which is disposed at the other of the positions facing the axial cross section of the onion and is cut by the cutting means in the onion, while changing the setting in the length direction of the onion. Equipped with cutting position changing means, A control means for controlling the cutting means to stop when the amount of light output detected by the step exceeds a preset value for judging that the preset cutting is completed is provided. This is an onion cutting device.

According to the first aspect of the present invention, the light projecting means and the light receiving means are respectively arranged at the outer position of the peripheral surface of the onion and the position facing the axial cross section of the onion. From this light projecting means, the light is projected toward the diameter (axial direction) of the long onion or the axial cross section of the long onion stem, and the light emitted through the axial cross section of the long green onion or the circumference of the long green onion is emitted. The amount of emitted light is detected by the light receiving means. By the way, when the root part of the root remains in the cut part of the long green onion, the light emission amount is small. However, when the root portion is appropriately cut by the cutting means, the cutting portion becomes a stem portion, and the root portion of the root that blocks or attenuates light disappears, and the light output amount increases.

Therefore, in claim 1, the cutting position changing means gradually moves the position of cutting the leek in the length direction of the leek, while detecting the light emission amount and detecting the light emission. When the light amount exceeds a preset value for judging that the preset cutting is completed, control is performed so as to stop the cutting of the long green by the cutting means. For this reason,
Since the cutting means can be stopped when the cutting means cuts off the waste of long onion, only the waste of long onion can be reliably cut and removed.

According to a second aspect of the invention, the control means is
When the light output amount of the light detected by the light receiving unit is less than or equal to the specified value, the cutting position changing unit moves the cutting unit and the cutting unit controls the cutting to be repeated stepwise. The cutting processing apparatus of the long green onion according to claim 1.

In the invention according to claim 2, the control means constantly monitors the light emission amount of the light detected by the light receiving means, and judges that the light emission amount is preset and the cutting is completed. If it does not exceed the specified value, it is judged that cutting is still insufficient and roots remain. When it is determined that the roots remain, the control means drives the cutting position changing means again to slightly move the position of cutting the leek in the length direction of the leek, and after the completion of the movement, the cutting means. Is started to cut the long green onion, and after the cutting, the cutting means is stopped to end the cutting. After the completion of the cutting, the control means determines again whether or not the light emission amount of the light detected by the light receiving means exceeds the specified value. If the output amount of light detected by this determination does not exceed the specified value, the control means still determines that the cutting of the root of the root is insufficient, and drives the cutting position changing means again, The position at which the onion is cut is slightly moved in the length direction of the long green onion, and after the movement is completed, the cutting means is started to cut the long green onion, and the cutting means is stopped to complete the cutting of the long green onion. After that, the control unit determines again whether or not the light emission amount of the light detected by the light receiving unit exceeds the specified value. In this way, the movement of the cutting means and the cutting by the cutting means are repeated until the light output amount of the light detected by the light receiving means exceeds the specified value. With these, the cutting means cuts off the waste portion carefully without waste without overcutting the non-disposal portion which does not need to be discarded, such as the long green stalk portion, so that only the waste portion of the long green onion can be surely cut and removed. You can Further, since the cutting means for cutting repeats starting and stopping and is not always started, it also contributes to power saving and improvement in durability of the cutting means.

According to a third aspect of the present invention, among the light projecting means and the light receiving means, the one arranged outside the peripheral surface of the onion is a support for contacting the peripheral surface of the shaft of the onion. The onion cutting apparatus according to claim 1 or 2, wherein a guide hole that is provided inside the member and that guides the light is formed in the support member.

According to the third aspect of the present invention, the light projecting means or the light receiving means is provided in the supporting member which abuts the peripheral surface of the shaft (stem) of the onion, and the light projecting means is provided in the supporting member. Guide holes for guiding the projected light or the light directed to the light receiving means are formed. The light projected and guided by the light projecting means through the guide hole formed in the support member is efficiently projected onto the peripheral surface of the long onion without leaking outside the support member. That is, the light projected from the light projecting means can be surely introduced into the onion. Therefore, it becomes possible to accurately and accurately detect the amount of light emitted from the projected light through the axial cross section of the onion in the axial direction of the onion, and accurately detect only the discarded part of the onion. It can be surely cut and removed.

A protective cover 16 is provided between the base 11 and the rotary blade 12. The protective cover 16 has a disk shape, and a base-shaped sensor window 16 </ b> A is cut out in a part of a circumferential portion of the protective cover 16.
It is also rotated by the motor 13. The sensor window 16A does not have to have a base shape, and may be a window formed by hollowing out the protective cover 16. The sensor window 16A is formed at a position opposite to the rotary blade 12 with the center of rotation of the protective cover 16 interposed therebetween. The position of the sensor window 16A is determined by the protective cover 16 when the rotary blade 12 is cutting the long green N.
Is formed at a position where it is protected from the cutting waste of the long onion N, the rotary blade 1 is inserted through the center of rotation of the protective cover 16.
It does not have to be at the position opposite to 2. In addition, at the moment when the rotary blade 12 does not cut the long onion N, the light from the projector 21S reaches the light receiving sensor 14 from the cut surface of the long green N via the sensor window 16A. As described above, in order to protect the light receiving sensor 14 from the cutting waste of the long green N when the long green N is cut by the rotary blade 12, the size and the number of the sensor windows 16A are appropriately considered. To be By rotating the rotary blade 12 and the protective cover 16 in this manner, the light emitted from the cut surface of the long onion N and reaching the light receiving sensor 14 is repeatedly passed and blocked.

Further, behind the base 11, as shown in FIG.
As shown in, a motor cylinder 17 corresponding to the cutting position changing means of the present invention is provided. The tip of the motor cylinder 17 is connected to the base 11, and by driving the motor cylinder 17, the rotary blade 12 is moved through the base 11 in the depth direction of the green onion N (Y direction in FIG. 1). To be able to move forward. Of course, by driving the motor cylinder 17 in reverse, the base 11
Can be retracted.

Further, at the front position of the cutting device 7, there is provided a pressing member 8 for pressing and holding the root of the long onion N against the conveying member 6 when cutting the root of the long onion N.
FIG. 5A is a front view of the pressing member, and FIG. 5B is a front view showing the positional relationship between the pressing member and the cutting blade. The pressing member 8 has a pressing pad 21 corresponding to the supporting member of the present invention that presses the long onion N against the conveying member 6, and a support bar 22 having an inverted Y shape is provided on the front side of the pressing pad 21. It is arranged. This support bar 22
Is urged downward by a spring 23. Further, the pressing member 8 has a supporting arm 24 for moving the pressing pad 21 and the supporting bar 22 up and down by an air cylinder (not shown). Then, the pressing pad 21 and the support bar 22 are lowered by the support arm 24, whereby the pressing pad 2
The end portion of the long green onion N can be pressed by 1 and the conveying member 6. Further, since the support bar 22 is biased downward by the spring 23, the support bar 22 can support the long green N. Further, since the support bar 22 has an inverted Y shape, it also plays a role of guiding the onion N to the central position of the conveying member 6 when the onion N is bent, for example. . In this state,
Rotate the rotary blade 12 of the cutting device 7 as shown in (b),
The root of the long onion N is cut.

FIG. 6A is a rear view of the pressing member,
FIG. 6B is a partially cutaway side view of the pressing member. As shown in the figure, in the pressing pad 21, a projector 21S, which is a light projecting means of the present invention that projects light toward the peripheral surface of the shaft (stem) of the long green N, is provided from the peripheral surface of the long green N. They are arranged at positions separated from each other in the axial radial direction. In addition, the projector 21
A guide hole 21H corresponding to the guide hole of claim 3 for surely guiding the light projected from S to the peripheral surface of the shaft of the long green N is formed in the pressing pad 21. In this way, the light projected from the projector 21S is reliably guided to the peripheral surface of the shaft of the long onion N through the guide hole 21H formed in the pressing pad 21, and enters the long onion N via this peripheral surface. Light is emitted, and a part of the light leaks out in the length direction of the onion N through the axial cross section of the onion N.

The holding pad 21 is made of an elastic material such as sponge. When the holding member 8 is pushed down and the holding pad 21 comes into contact with the peripheral surface of the long onion N, the tip portion of the holding pad 21 is long. It is designed so that it extends and adheres in the covering direction along the peripheral surface of the onion N axis. Figure 6
As shown in (a), due to the sealing effect of the tip portion of the pad 21, it is possible to prevent light from leaking from the peripheral surface of the onion N in a substantially half circumference.

However, the peripheral surface, which is the other half circumference of the onion N, is not covered by the tip portion of the pad 21, and the light leaks out from there. Therefore, in the present embodiment,
As shown in FIGS. 6A and 6B, when the pressing pad 21 is pushed down by the support arm 24 and the pressing pad 21 made of an elastic member contacts the long green N, the guide hole 21H in the pressing pad 21 is formed. The position is arranged so as to be on the Y-shaped root mounting base 6C of the transport member 6 via the long onion N. In this way, by sandwiching the long onion N with the elastic member of the pressing pad 21 and the Y-shape of the root mounting base 6C, the tip end of the pad 21 is fixed to the root mounting base 6C.
Due to the sealing effect of the corners P1 and P2 of the pad 21 that comes into contact with the pad 21, light leaking from the other half-circumference of the onion N is also surrounded by the root mounting table 6C of the transport member 6 and the corners P1 and P2. It will not leak out from the enclosed space. Moreover, as shown in FIG. 6 (b), the width of the root placement table 6C is sufficiently wider than the width of the guide hole 21H, so that the sealing effect is more effective and the leakage of light is more reliably prevented. it can.

With these, most of the light projected from the projector 21S to the long onion N is emitted in the length direction of the long onion through the axial cross section of the long onion N while suppressing the leakage of the light as much as possible. Therefore, it is possible to detect the amount of light emitted by the light receiving sensor 14 with higher accuracy.

An optical sensor 9 is provided upstream of the pressing member 8 of the cutting apparatus 1 shown in FIG.
It is detected whether or not the long onion N is present in the lower position of the position, and the presence signal at that time is transmitted to the control means of the present invention, for example, the control device 10 comprising a programmable logic controller (PLC). The control device 10 is a long green N
Is present and the presence signal is received, the long-green onion cutting process is performed according to the program in the control device 10. Control device 10
In (1), it is determined whether or not a light receiving signal (ON signal) from the light receiving sensor 14 is input, and whether or not the light receiving signal is input is confirmed. Then, according to the presence / absence of the light reception signal input, driving and stopping of the cutting device 7 and the motor cylinder 17 are instructed.

Next, the procedure of the cutting processing of the long green onion in the long green cutting processing apparatus 1 having such a configuration will be described. FIG. 7 is a flowchart showing the procedure of the cutting processing of the long green onion in the cutting processing apparatus of the long green onion according to the present invention. Before starting the cutting process of the long green onion, a specified value R for determining ON of a photoelectric switch (not shown) is set by adjusting the amplifier sensitivity of the optical sensor (S0). This specified value R is the light receiving sensor 14
When the intensity of the light received through the light source exceeds a certain standard, it serves as a standard for determining that the cutting between the root portion and the stem portion of the long onion N is properly performed. Therefore, for example, several long green onions N are experimentally cut and the amount of light received by the light receiving sensor 14 when it is determined that they have been appropriately cut is measured. This amount of received light is set as a specified value R at which the photoelectric switch is turned on. When the amount of light received by the light receiving sensor 14 exceeds the specified value R, the photoelectric switch is turned on and the control device 10 is turned off.
The N signal is output. When the value is less than the specified value R,
An ON signal is not output from the light receiving sensor 14 to the control device 10. When starting the cutting process of the long green onion, when a worker (not shown) puts the long green N on the conveying member 6 and presses a start switch (not shown), the motor M is activated and the conveying member 6 starts to move and is mounted on the conveying member 6. The stripped green onion N is conveyed and passes under the optical sensor 9. The optical sensor 9 detects whether or not the long onion N is present on the conveying member 6 that has passed (S1).

The conveying member 6 carrying the long onion N is conveyed to the position of the cutting device 7 after passing under the optical sensor 9, and is stopped when the position of the cutting device 7 is reached (S).
2). In addition, when the long green N is not mounted on the transport member 6, the transport member 6 passes through without being stopped. At this time, the rotary blade 12 in the cutting device 7 is located at the origin position. Next, when the conveying member 6 stops, the support bar 22 of the pressing member 8 descends, and the support bar 22 presses the long onion N so as not to move it toward the central position (S3).

When the support bar 22 presses the long green N, the base 11 and the rotary blade 12 pivotally supported by the base 11 are advanced together with the protective cover 16 in the direction of the long green N by the motor cylinder 17. At this time, the rotation of the rotary blade 12 is stopped.

When the rotary blade 12 is advanced in the direction of the long onion N and reaches the root of the long green N, the rotary blade 1
The forward movement of 2 is stopped (S4). Subsequently, the rotary blade 12 is rotated by the motor 13 to cut the root of the long onion N at a predetermined rotation angle and stop the rotation (S5).

After cutting the root of the long green onion with the rotary blade 12,
The light receiving sensor 14 is projected on the shaft (stem) peripheral surface of the long onion N by the light projector 21S arranged in the pressing pad 21, and then, in the axial direction of the long green onion through the axial cross section of the long onion N. Detect the light that comes out. Based on the detected light intensity, that is, when the light intensity exceeds the specified value R, the ON signal of the photoelectric switch is output to the control device 10 (S6).

The control unit 10 always turns on the photoelectric switch.
The presence / absence of a signal is confirmed, and control is instructed according to the presence / absence of this signal (S7). If the ON signal of the photoelectric switch has not been input, the control device 10 proceeds to step (S
4), (S5), (S6), and (S7) are issued again. When the ON signal is not output from step (S7), the cutting device 7 has not cut the long green onion sufficiently, so that the control device 10 causes the received light to exceed the specified value R, and the photoelectric switch. Repeats steps (S4) to (S7) until it transmits an ON signal. Next, when the detected light exceeds the specified value R and the photoelectric switch becomes an ON signal, the rotary blade 12 is in a stopped state as in step (S5), and immediately moves to the next step and the cutting device The cutting work by 7 is completed (S8).

After completion of the above step (S8), the cutting device 7
To the origin position from the cutting point of long green N (S
9).

After that, the holding member 8 holding the onion N is lifted and returned to the original position (S10), and then the conveying member 6 is moved to be carried out to the downstream side (S11). And
When the conveying member 6 reaches the most downstream portion of the cutting apparatus 1, a worker (not shown) takes out the long onion N from the conveying member 6 and the cutting process of the long onion N ends.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments.
For example, the motor 13 that drives the rotary blade may be a rotation speed control motor. Moreover, regarding the advancement and rotation of the rotary blade 12, the step of advancing the rotary blade 12 and the step of rotating the rotary blade 12 may be performed at the same time. The optical sensor that confirms that the long green onion is mounted on the transport member 6 may be a sensor that uses a medium other than light, such as an ultrasonic sensor.

On the other hand, in the above-described embodiment, the light projector, which is the light projecting means, is arranged on the peripheral surface of the onion, and the light receiving sensor, which is the light receiving means, is provided at the position facing the axial cross section. However, this arrangement is reversed. May be. Thus, by arranging the light projecting means at a position facing the axial cross section of the onion and arranging the light receiving means on the peripheral surface of the onion, the degree of freedom of the installation location of the light receiving means is expanded, and the onion cutting device Not affected by the layout restrictions of the. Further, it becomes easy to select a position where the light receiving means can easily receive light, and the number of light receiving means is increased, or
It also becomes possible to adopt a light receiving means having a wide light receiving area.

Further, in the above-described embodiment, the specified value R as a root cutting reference of the long onion N is based on the ON signal of the photoelectric switch by adjusting the sensitivity of the amplifier of the optical sensor, and the ON signal of the photoelectric switch is used to cut the long onion cutting device. However, it is also possible to set a prescribed value R in advance in the control device, and determine the completion of the cutting of the long onion root from the result of comparison with the analog value received by the light receiving sensor and control it.

[0036]

As described above, according to the invention according to claim 1 of the present invention, only the light that enters the long green onion and is emitted in the axial length direction through the axial cross section of the long green onion is detected. Therefore, it is possible to accurately detect the amount of emitted light. The cutting means is stopped immediately when the cutting means cuts off the long litter discard part in order to judge whether the cutting means is stopped or continued based on the detected light output amount and the preset value for judging that cutting has been completed. Therefore, it is possible to accurately cut and remove only the long green onion waste portion. According to the invention of claim 2, when the cutting means cuts off the waste of the long onion, the cutting is repeated more carefully and gradually in the vicinity of the waste of the long onion, and after the waste of the long onion is cut. Since the cutting means can be immediately stopped, it is possible to appropriately and reliably perform more highly accurate long green onion cutting. The cutting means is operated and stopped diligently in stages to save power, and because it is a cutting blade that uses a motor controlled by rotation angle control, it is a rotation speed control motor that constantly rotates. It is also possible to suppress overcutting of long green onions due to its inertia. Furthermore, since the cutting blade is rotated only at a certain rotation angle and is frequently rotated and stopped, the motor body and cutting blade are less worn compared to a motor that constantly rotates, and the durability of the motor and cutting blade is improved. The life can be greatly improved. According to the invention of claim 3, the light from the projector is surely guided into the shaft through the peripheral surface of the onion, and further, the light in the shaft is prevented from leaking out on the way, so that the suppressing effect is obtained. As a result, a sufficient amount of light emitted in the axial direction of the onion through the axial cross section of the onion can be secured. This can improve the detection accuracy of the light receiving means.
