BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onion root peeling device which allows an operator to perform root cutting and peeling of long green onions in a series of operations.

[0002]

2. Description of the Related Art Conventionally, as a root cutting and peeling device for long leeks, which is capable of performing root cutting and peeling of long leeks with a single device, for example, one disclosed in Japanese Patent Laid-Open No. 10-28570 ( First conventional example) and Japanese Patent Laid-Open No. 2000-
The one described in Japanese Patent No. 37180 (referred to as a second conventional example) is known.

FIG. 10 is a view showing a first conventional example, (a) is a front view, and (b) is a partially cut side view. This device
A tubular guide 1 through which a high-speed airflow is circulated and a long green onion N can be inserted, and the bottom end of the long green onion N inserted in the tubular guide 1 is received and positioned, and the root N1 generated from the bottom end is transmitted by the high-speed airflow. It has a stopper 2 for causing it and a scissor-shaped cutter 3 for cutting the base of the long onion N in this state. When the operator inserts the long onion N into the tubular guide 1 and abuts the bottom end of the long onion on the stopper, the stopper 2 retracts upward as shown by an imaginary line in FIG. The root is cut, and the skin (outer skin) is peeled off by high-speed airflow.

FIG. 11 is a view showing a second conventional example. (A) is an external perspective view, (b) is a partially omitted plan view, (c) is a partially omitted side view, and (d) is an enlarged root cutting portion. A plan view and (e) are enlarged perspective views of the root cutting portion. This device includes a root cutting portion 10 for cutting the root of the long onion N and a peeling portion 20 for peeling the long onion N. Root cutting part 10
Is a holding table 11 that holds the root of the long onion N, positioning plates 12a and 12b that position the cutting position, a cutter 13, and a thickness detector 14 that detects the thickness of the long onion N.
And a root detector 15 for detecting roots of long onions. The skin peeling section 20 has a leek detector 21 for detecting the presence or absence of the long leek N, a tubular guide 22 having an open upper side, and a nozzle 23 for ejecting air toward the center of the guide 22. As shown in FIG.
When the long onion N is inserted so as to pass through the thickness detector 14 above, the thickness detector 14 detects the thickness of the long onion N in the process, and the thickness of the long onion N is detected in accordance with the thickness of the long onion N as shown in FIG.
2) to (c4), the holding table 11 and the positioning plates 12a and 12b move in plan view. That is, when the spring onion is thin, as shown in FIG. (C2), its root moves so as to hit the positioning plate 12a, and when the spring onion has a medium thickness, it is shown in FIG. (C3). Thus, when the root moves so as to hit the positioning plate 12b, and the spring onion is thick, the positioning plate 12b is positioned so that the root hits the positioning plate 12b as shown in FIG. (C4).
Moves to the right in the figure and recedes upward in the figure. Note that FIG. (C1) is a diagram showing an initial state before the movement. Then, when the root part of the long onion N is detected by the root detector 15, the cutter 13 moves and the root part is cut.
After that, when the root part of the long onion N is no longer detected by the root detector 15, the above parts return to the initial positions. After that, the worker lowers the long onion N downward, and when this is detected by the onion detector 21, air is ejected from the nozzle 23, so that the skin is peeled by pulling the long onion N as shown in FIG. Will be punished.

According to the first or second conventional example as described above, it is possible to cut and peel the root of the long onion N with a relatively small device without carrying the green onion by a belt conveyor or the like. .

[0006]

When the skin of long onion N is blown off with air, the passage (air passage) of the blown-off skin is
If there is a member such as a cutter or a positioning plate, the skin will be caught on it. In the first conventional example, the root of the long onion N is cut and peeled at the same position (inside the tubular guide 1), so it is necessary to retract the stopper 2 at least at the time of peeling. There is a problem that the device becomes complicated by the amount of the mechanism. Further, in this first conventional example, since the stopper 2 is retracted before cutting the root portion, the root portion is not supported by the stopper 2 when the root portion is cut. Therefore, there is also a problem that the work cannot be performed easily because the cutting cannot be performed in a stable state. Moreover, according to FIG. 10B, since the air is jetted near the root of the long onion N, the leeks should not be peeled off in this configuration.

In the second conventional example, even if the root cutting portion and the peeling portion of the root of the long onion N are not in the same position, they are close to each other in the vertical direction, and therefore, the holding table 11 is also used when peeling.
It is necessary to retract the positioning plates 12a and 12b from each other, and the retracting mechanism complicates the device. In addition, in the second conventional example, the worker
As shown in (a), there is no guide above the guide 22 for inserting the long onion N so as to pass through the thickness detector 14 (when peeling, it is necessary to lower the onion as it is. The upper part of the guide 22 2
2a must be kept, and the guide surface cannot be provided below), so there is a problem that it is difficult to insert leeks. Further, the upper part of the guide 22 is always open 2
2a (because it is opened at the time of air injection), its noise becomes large, and since the cutter 13 is also a rotary blade rotated by a motor, its noise and noise at the time of cutting also become large.

The object of the present invention is to solve the above problems, and with a simple structure, the root cutting and peeling of long leeks can be easily performed by a series of operations, and the root cutting of long leeks with low noise is achieved. It is to provide a peeling device.

[0009]

In order to achieve the above-mentioned object, a long-scallion root peeling device according to claim 1 is for cutting the main body of the device and the root part of the long-scallion provided on this main body. A device comprising a root cutting part and a peeling part for peeling long onions, wherein the root cutting part is a non-rotating knife-shaped cutter provided in the rear part of the main body so as to be able to travel in the left-right direction. , A leek pushing guide surface that guides the root of the long leek pushed toward the running surface of this cutter,
An abutting plate that is located behind the traveling surface of the cutter and that is pushed by the root of the long onion and swings rearward; and an abutting plate that is arranged behind the abutting plate and that limits the backward swinging of the abutting plate. In addition, the cutter detecting means for detecting the rearward swing of the abutting plate, and the traveling means for running the cutter in the cutting direction when the rearward swing of the abutting plate is detected by the detecting means. And the peeling portion is a recessed portion that is continuous to the left or right with respect to the spring onion pushing guide surface in the root cutting portion, and the bottom thereof is at a position lower than the spring onion pushing guide surface. The leek pulling portion that constitutes the pulling guide surface, the peeling detection means that detects that the long leek has been placed in the leek pulling portion, and the recessed portion is moved upward when the long leek is detected by the peeling detection means. To cover from A closing cover, a cover detecting means for detecting that the cover is closed, and a front part to a rear part toward the long leek in the recess when the cover detecting part detects that the cover is closed. It has an air nozzle for injecting air toward, further
In addition, the abutting plate is a plan view of the cutter traveling.
It is inclined with respect to the surface, and
Change the position of the base of the long onion against the plate
A plurality of guide parts are provided, and each guide part is
When traveling in the cutting direction of the cutter,
It is said to be a guide part that supports long onions on the flow side.
In addition, the cutter presses the long leek against the above leek pushing guide surface
It is characterized by cutting while cutting . A long-scallion root-peeling device according to claim 2 is the long-scallion root-peeling device according to claim 1 , wherein the cover is opened and closed about a rotation center axis extending in the front-rear direction of the main body, and an opening operation thereof. Sometimes, the root cutting portion side is opened.

[0010]

With the above-mentioned structure, the long-scallion root-peeling device according to claim 1 is used in the following manner, and has a unique effect. First, the worker holds the leaf of the long onion and presses the root portion against the butting plate so that the root portion is along the green onion pushing guide surface. Then, the abutting plate swings backward, and when this is detected by the cutter detecting means, the cutter travels in the cutting direction and the root portion is cut. Next, the worker holds the leaf of the long onion and puts the long onion in parallel into the recess of the skin peeling section, and when this is detected by the peeling detection means, the recess is covered from above. Then, the cover is closed, and when this is detected by the cover detecting means, air is jetted from the front part toward the rear from the air nozzle toward the long onion in the recess, so that the operator holds the leaf part of the long onion. The long leek is pulled out from the recess while keeping it along the leek pulling guide surface which is the bottom of the recess. This will result in peeling. As described above, according to the long-scallion root-cutting and peeling device, the long-stem root cutting and peeling can be easily performed by a series of operations. Then, since the green onion pushing guide surface in the root cutting portion is arranged to the left or right of the concave portion forming the skin peeling portion, and the butting plate is arranged at the rear thereof, this butting The plate is not located in the stripped skin drainage passage. Therefore, a mechanism for retracting the butting plate is unnecessary, and the structure is simpler than that of the conventional one. Further, since the cutter is not a rotary blade but a knife-shaped cutter that rotates in the left-right direction and does not rotate, its operating noise is significantly reduced. Furthermore, since the peeling portion is closed so that the concave portion is covered with the cover, air is jetted, so that the noise is also significantly reduced. As described above, according to this root leek debarking device, with a simple structure, it is possible to easily perform root cutting and peeling of long leek in a series of operations, and it is possible to obtain an effect that noise is small. . Further, the abutment plate is inclined with respect to the traveling surface of the cutter in a plan view, and the abutment position of the base of the long onion with respect to the abutment plate is different from that of the main body. Since a plurality of guide portions are provided, the cutting length of the root portion varies depending on which guide portion the base portion of the long onion is along and pressed against the abutting plate. Therefore, the operator can select which of the guide parts along the base of the long onion is to be pressed against the butting plate.
The root can be selectively cut to the desired length.
Further, each guide portion is a guide portion that supports a long onion on the downstream side in the traveling direction of the cutter when the cutter travels in the cutting direction, and the cutter cuts while pushing the long onion against the green onion pushing guide surface. Therefore, the cutting of the root portion can be performed very smoothly. According to the root onion peeling device for long onions of claim 2 , in the root peeling device for long onions according to claim 1 , the cover is opened and closed around a rotation center axis extending in the front-rear direction of the main body, and Since the root cutting portion side is opened during the opening operation, the long leek can be moved extremely smoothly from the root cutting portion to the peeling portion.
