Description

  The present invention relates to a long leek processing apparatus that removes unnecessary materials such as the outer skin of the harvested long leek, soil and sand adhering to the surface, and cuts the roots of the long leek. The present invention relates to a long onion processing apparatus that can be carried out automatically.

  A number of semi-automatic or fully-automatic processing devices have been proposed by various methods as processing devices for rooting or peeling long onions.

  As a device for root cutting of long onions, hold the leaf part side of the long onion in the hand and insert it into the root cutting device until the tip of the root side comes into contact with the stopper. There is one that performs root cutting (Patent Document 1).

  In addition, as a long-onion skinning device, a long onion is placed on a leek mounting portion having a soundproof opening / closing lid, the opening / closing lid is closed, and air is blown out from an air nozzle when the detecting means is detected. There is one that blows away the soil on the surface of the long onion and peels the skin (Patent Document 2).

Furthermore, as a long-onion rooting and skinning device that can perform both root cutting and skinning of a long onion, a root-cutting unit that performs root-cutting of the long onion into the main body of the device and a long-onion using a jet of air When the long leek is inserted to a predetermined position on the main body of the device, the root part of the long leek is cut by the root cutting part, and then the skin of the long leek is peeled by the skin peeling part. (Patent Document 3).

In this way, in a device that can perform both root cutting and skinning of a long onion with a single device, the large onion that has been rooted is transported and peeled off by a belt conveyor or the like. This eliminates the need for additional equipment and enables a relatively small apparatus, which has the great advantage that individual producers can perform root cutting and skinning immediately after harvesting long onions.

  However, in a device that can perform both root cutting and skinning processing in one machine, since a single green onion is stripped after root cutting processing, a large amount of long green onion is processed. In this case, if all of the long onions are first rooted and then the processing procedure is performed to peel the rooted green onions one by one, even if expeditious processing can be performed, Long onion processing according to the processing procedure cannot be realized.

  By the way, the root cutting device and the skinning device may be attached to a common base. However, the root cutting position of the conventional root cutting device is determined at the position where the root portion of the long onion is inserted into contact with the stopper.

  Long spring onions can be roughly divided into leaves, roots with roots, and stems between the roots and leaves in the length direction, and straight from the leaves to the roots. Many are not only straightly stretched but also three-dimensionally bent.

  For this reason, if root cutting is performed by inserting the long onion until it comes into contact with the stopper, it is difficult to cut at a desired cutting position, and it is considered that cutting is excessive or insufficient.

  Further, in the skinning device, it has been desired that cleaning after use can be easily performed because long onion juice, attached soil, peeled skin, etc. give off dirt and odor.

  On the other hand, the length of the long onion is divided according to the diameter of the stem part, and the grade is divided according to the soft white length, which is the length of the soft white part from the root end to the leaf part.

  For such class and class selection, a method is generally used in which an operator applies a gauge in a separate process and discriminates after the rooting and skinning processes are completed. For this reason, since work efficiency was bad and the number of times of leek handling was large, there was a tendency to hurt a leek.

Root cutting device 200
The root cutting device 200 is disposed on the top of the base plate 2 and a root cutting base 201 that also functions as a fixed blade fixed to the top of the base plate 2 and a positioning function for determining the root cutting position of the long onion N. A movable blade 202 that can move in the left-right direction on the back side of the root cutting table 201, and a cutting position that cuts the root of the long onion N on the root cutting table 201 and a standby position where the movable blade 202 is separated from the root cutting table 201. For example, a slide cylinder that is driven by compressed air attached to the back side of the base plate 2 is used as the actuator 203.

  As shown in FIG. 5, the root cutting table 201 is formed in a substantially concave shape when viewed from the front, and the root portion N <b> 1 of the long onion N is placed in the concave portion 204.

  As shown in FIGS. 5 and 6, the flange portion 205 protrudes inward along the bottom surface from one side of the deep portion of the concave portion 204, and as shown in FIG. 6, the edge 206 of the flange portion 205 is just the edge 206. Engage with the constricted portion N6 of the root of the long onion N. Specifically, the root portion N1 of the long onion N is placed in the concave portion 204 of the root cutting base 201 so that the root portion sufficiently protrudes from the root cutting base 201 to the back side. At that time, the long onion N is made to hit the edge 206 of the flange portion 205. When the long onion N is pulled forward in this state, the outer peripheral surface of the long onion N abuts against the edge 206 of the flange portion 205 along the bend of the root portion N1 of the long onion N.

  As shown in FIG. 6, the root portion N1 of the long onion N has a slightly upper portion N5 bulged from the root of the root and a slightly upper portion N6 thereof.

  From such a shape of the vicinity of the root of the long onion N, when the long onion N is pulled to the near side, the constricted portion N6 is engaged with the edge 206 of the flange portion 205. Since this engaged state can be felt by hand, when the operator stops the pulling operation of the long onion N and turns on the cutting switch (not shown), the movable blade 202 moves from the standby position to the cutting position, The root of the long onion N placed in the recess 204 of the root cutting base 201 is cut. The cutting position of the movable blade 202 is such that the base of the root is located in a state where the constricted portion N6 of the long onion N is engaged with the end edge (edge) 206 of the flange portion 205. Since this position varies depending on the type of the long onion to be processed and individual long onions, it can be dealt with by adjusting the position as necessary.

  Thus, in the root cutting device 200 of the present embodiment, the root is cut at a cutting position at a predetermined distance from the constricted portion N6 of the root portion N1 in accordance with the wavy shape of the root portion N1 of the long onion N. It can be cut at the root of the root, which can increase the commercial value.

Soft white length discrimination device 300
The soft white length discriminating apparatus 300 is integrally formed by a support portion 301 that extends horizontally from the front edge of the machine base 1 toward the front side and a support frame portion (support portion) 303 that extends horizontally from the tip of the support portion 301 to the right. The support portion 301 is attached to the machine base 1 so as to be slidable in the front-rear direction. In addition, the stalk N2 side of the long onion N is carried on the carrying frame 303 in a state where the long onion N is set at the root cutting portion. The length L in the front-rear direction from the root cutting position (for example, the position of the movable blade 202) to the carrying frame portion 303 is a reference length for determining the soft white length, and indicates the length of the boundary of grade determination. ing. Therefore, the carrying frame portion 303 carrying the long onion N can be used as an index that can be visually recognized by the operator. In this case, if the soft white length is longer than the length L, it is judged as A grade, and if it is short, it is judged as B grade.

  A gauge portion 304 is formed on the surface of the support portion 301. The gauge displayed on the gauge section 304 is used to indicate the boundary used for determining the grade of soft white length, and is classified according to the type of long onion N (for example, by type, for spring onion, for summer onion, etc.). When this gauge is set to a plurality of display parts (not shown) (for example, the front end of the machine base 1), it can be easily adjusted to the reference length for determining the soft white length according to the type of the long onion N. .

  Therefore, the position of the carrier frame 303 is adjusted by adjusting the gauge part 304 of the support part 301 in accordance with the instruction part according to the type of the long onion N for which the grade is determined, and the carrier frame during the root cutting process is performed. Comparing the position of the portion 303 with the position of the soft white border N8 of the long onion N (the portion where the color of the stem changes from white to green), the soft white border N8 of the long onion N carried on the carrying frame portion 303 is If it is inside (on the root cutting device 200 side) from the position of the carrying frame portion 303, the soft white length is shorter than the length L, so it is determined as B grade, and the length of the long onion N carried by the carrying frame portion 303 If the soft white border N8 of the stem portion N2 is outside (near side) of the position of the carrying frame portion 303, since the soft white length is longer than the length L, it is easily and reliably determined as A grade.

  In the soft white length discriminating apparatus 300 according to the above-described embodiment, the length of the support portion 301 is adjusted so as to be aligned according to the type of the long onion N selected by the gauge portion 304 prepared in the support portion 301. Although the adjustment is performed, the support portion 301 is fixed to the machine base 1 and the gage portion 304 of the support portion 301 is divided into types of long leek N (for example, by type, for spring leek, for summer leek, etc.). Display the gauge. The plurality of gauges are displayed in accordance with a reference length for determining the soft white length, starting from the root cutting position (for example, the position of the movable blade 202). Since these gauges represent the actual border between A grade and B grade, the gauge corresponding to the type of the long onion N with the long onion N set in the root cutting part, and the softness of the long onion N The position that becomes the boundary N8 is visually compared, and if the position of the soft white boundary N8 exists on the side of the carrier frame 303 (outside) from the gauge, it can be determined as A grade, and otherwise it can be judged as B grade.

  In the case of discriminating three grades A, B, and C, a gauge indicating the boundary between the B grade and the C grade may be further provided in the gauge portion 304 of the support portion 301. At this time, two gauges are displayed for each type, which is confusing. Therefore, a dedicated soft white length discriminating device may be prepared for each type.

  The soft white length discriminating apparatus 300 is not limited to this configuration. For example, a support plate for supporting the long onion N placed on the root cutting apparatus 200 is provided extending from the machine base 1 to the front side. You may make it provide the mark which shows the boundary of a scale and a grade on a support plate.

Stem diameter measuring device 400
The stem diameter measuring device 400 includes a camera 401 for photographing the stem portion N2 of the long onion N placed on the root cutting device 200, and a light detection sensor or the like that the long onion N is placed on the root cutting device 200. (Not shown) for detecting the thickness of the stem (stem diameter) by image processing the image of the stem N2 photographed by the sensor 401, the illumination device (not shown) that illuminates the long onion N, and the camera 401. A processing unit, and a notifying unit 403 for notifying the diameter of the stem portion obtained by processing by the image processing unit and the class (L, LL, etc.) corresponding to the diameter by voice, or displaying the characters, symbols, etc. have.

  Further, the camera 401 is disposed between the root cutting device 200 and the skinning device 100, and is covered with a cover 404 having an opening facing the long onion N mounted on the root cutting device 200. The notification unit 403 is arranged on the cover 404. Note that the notification unit 403 of the present embodiment displays the diameter of the stem and the class (L, LL, etc.) corresponding to the diameter by characters, symbols, and the like.

  In the present embodiment, the camera 401 captures the stem portion N2 of the long onion N at a predetermined length position from the root cutting position. At that time, a background plate 405 is arranged at the background position of the photographing region so that the outline of the stem portion that is white of the long onion N to be photographed becomes clear. The image processing apparatus obtains the diameter of the stalk N2 of the long onion N by performing edge processing for extracting a contour on the photographed image of the stalk N2. Then, a class such as L, LL, and M is determined based on the obtained diameter, and the diameter and the class are displayed on a display device 403 serving as a notification unit configured by a liquid crystal panel, for example. Of course, the method of notifying the diameter and class may be a method of transmitting by voice other than the method of displaying on the display device and performing visual confirmation.

  As described above, while the long leek is placed on the root cutting device 200 and the long leek is being rooted, the grade determination based on the soft white length and the class determination based on the diameter of the stem N2 can be automatically performed. Therefore, it is not necessary to perform the determination of the equal class separately after the root cutting process, the work efficiency is dramatically improved, and the work of holding the long onion N is reduced correspondingly, so that the long onion N may be damaged. decrease. Although a camera and an image processing device are used as means for measuring the diameter of the stem N2 of the long onion N, a lighting device is arranged on one side across the stem N2, and the long onion N is on the opposite side. A large number of light receiving sensors are arranged along the radial direction, illuminated by an illuminating device toward the stem portion N2 of the long onion N, and the light is received by the many light receiving sensors, so that the stems from the region that did not receive the light. The diameter of the part N2 may be obtained.

  Similarly, the light emitting / receiving sensor groups may be arranged to face each other so that the long onion N is sandwiched between them, and the diameter of the stem N2 may be obtained.

  In the long onion processing apparatus of the present embodiment described above, the worker stands on the front side of the machine base 1. In the case of performing the rooting process by stripping the long leek N with the harvested soil attached one by one, for example, as shown by the two-dot chain line in FIG. 101 is directed toward the root cutting device 200 so that an operator standing in front of the root cutting device 200 can easily insert the long onion N into the skinning nozzle cylinder 101 at this position. When the long leek N is inserted into the peeling nozzle cylinder 101, the skin N4 of the long leek N is peeled off. Therefore, the operator takes out the long leek N from the peeling nozzle cylinder 101 with, for example, the right hand and places it on the rooting device 200 as it is. . When the long onion N is pulled to the front side with the right hand and the constricted portion N6 of the long onion N engages with the edge 206 of the flange portion 205 of the root cutting base 201, the cutting switch provided on the base plate 2 is opened. By operating with the left hand, the movable blade 202 slides and cuts at the root of the root. Thus, the operator holds the leaf portion of the long onion N with the right hand and operates the cutting switch with the left hand, so that the hand does not touch the movable blade 202 by mistake when the movable blade 202 is operated.

  In addition, as described above, the long onion N is not subjected to the peeling process and the root cutting process one by one, but first, a plurality of long onions are peeled off, and then a large number of long onions N that are peeled off are removed. 1 is placed on the right side of the machine base 1, for example, a container containing a large number of green onions is placed, and the peeling nozzle cylinder 101 of the peeling apparatus 100 is in a straight direction indicated by a solid line in FIG. By doing so, the peeling work on the right side of the machine base 1 can be performed. At that time, if the skinning nozzle cylinder 101 is inclined downward, for example, the skinning operation can be performed while the operator is sitting on a chair.

  In this way, the peeling device 100 and the rooting device 200 are separately provided so that the orientation of the peeling device 100 can be changed in accordance with the posture and working method of the operator. , Long onion processing can be performed according to the work procedure of the operator.

  Moreover, when rooting the long onion N, it is possible to determine the grade based on the soft white length and the class based on the stem diameter simply by placing the long onion N on the root cutting device 200. There is little damage of leek.

  Furthermore, since the grade and class are selected based on the root cutting position, accurate selection can be performed.
