  Then, in a state before the long onion 2 is clamped by the both clamping plates 42, both the rotating arms 41 abut against the stopper body 46 by the urging force of the urging body 35, and both the rotating arms 41 are brought into contact with this. In the approaching direction is restricted, and the distance between the sandwiching bodies 34 is the minimum value.

  The nozzle body 31 can reciprocate in the left-right direction with a predetermined rotation angle α about the rotation center axis A in the vertical direction with respect to the rotation arm 41 of the holding body 34. In other words, the two nozzle bodies 31 having a letter C shape in a plan view are arranged such that the tip end portion (injection hole) of the nozzle body 31 with respect to the main body portion 2e of the long onion 2 inserted between the two nozzle bodies 31 spaced apart from each other. ) Can be reciprocated in the horizontal direction which is the horizontal direction so that it moves in the contact / separation direction.

  Here, the predetermined rotation angle α is inclined inward with respect to the front-rear direction so that the tip side is closer to the main body 2e of the long onion 2 and the front end is inclined to the main body 2e of the long onion 2. The nozzle body 31 that is in the closest state (approached state) is also slightly inclined inward and the tip portion is the most separated from the main body 2e of the long onion 2 (separated state).

And an on-off valve (not shown) provided in the middle of the connecting pipe 64.

  The rotation drive means 32 has a rotating body 66 that is a rectangular parallelepiped rotor that rotates in a predetermined direction (for example, a clockwise direction in FIG. 4) around the rotation center axis B in the vertical direction. ing. A drive motor 33 that rotates the rotary body 66 in a predetermined direction is disposed below the rotary body 66, and a vertical motor rotation shaft 33a of the drive motor 33 is connected and fixed to an eccentric position on one side of the rotary body 66. ing.

  A base end portion (front end portion) of one elongated plate-like interlocking body 67 is rotatably connected to an eccentric position on the other side of the rotating body 66 via a vertical axis 68, and the other end of the same shape. A base end portion (front end portion) of the interlocking body 67 is rotatably connected through the same shaft 68. For example, the left interlocking body 67 that is the other interlocking body 67 is disposed above the right interlocking body 67 that is one interlocking body 67.

  The front end portion (rear end portion) of one interlocking body 67 is rotatably connected to the connecting plate portion 54 of the main body support frame 51 of the one nozzle body 31 via a shaft 69 in the vertical direction. The front end portion (rear end portion) of the interlocking body 67 is rotatably connected to the connecting plate portion 54 of the main body support frame 51 of the other nozzle body 31 via a vertical shaft 69.

  When the drive motor 33 is driven, the rotating body 66 rotates in a predetermined direction, and along with this rotation, the pair of left and right interlocking bodies 67 swings in conjunction with each other. Both nozzle bodies 31 are reciprocally rotated in the left-right direction with a predetermined rotation angle α around the rotation center axis A.

  On the other hand, as shown in FIGS. 1 and 6 and the like, the long leek processing apparatus 1 includes a long leek detection means 71 for detecting the long leek 2 inserted between the two nozzle bodies 31, and the long leek detection means 71. And a control means 72 for controlling the drive of the drive motor 33 based on this detection.

  The long onion detection means 71 is, for example, a reflection type optical system sensor that projects detection light from the light projecting unit and receives reflected light reflected by the long leek 2 by the light receiving unit. Is disposed in the vicinity of the right nozzle body 31. The control means 72 is electrically connected to the drive motor 33, the long onion detection means 71, the open / close valve of the high-pressure air supply means 60, and the like.

  Next, the operation of the long onion processing apparatus 1 will be described.

  For example, the plurality of long onions 2 that have been harvested from the field and are not uniform in length are temporarily placed on the upper plate 12 of the apparatus body 4.

  First, before starting the processing operation, the worker stands in front of the long onion processing apparatus 1 to check whether the direction of the skin peeling means 7 is the direction suitable for him or not. The direction of the skin peeling means 7 is adjusted to rotate.

  First, the operator lifts one long leek 2 with its longitudinal direction aligned with the left-right direction, and inserts the long leek 2 in the left-right direction into the space 15 below the upper plate 12. Then, it is placed on the long leek placement surface 14 of the device frame 11.

  At this time, the root part 2a of the long onion 2 is placed on the support part 23 of the root part conveying body 22 of the root part cutting means 5, and the leaf tip part 2b of the long onion 2 is placed on the leaf tip part 6 of the leaf tip part cutting means 6. Placed on the support 28 of the part transport body 27.

  In this state, when the operator operates an operation unit such as a switch for starting work, the root part transport body 22 and the leaf tip part transport body 27 are simultaneously rotated at a predetermined rotation angle about the rotation drive shaft toward the rear. Rotate only.

  Then, the root part 2a of the long onion 2 moves to the root part cutting blade 21 side and is cut by the root part cutting blade 21, and the leaf tip part 2b of the long onion 2 moves to the leaf tip part cutting blade 26 side. It moves and is cut | disconnected by this leaf-tip part cutting blade 26, As a result, the length of the long onion 2 becomes fixed.

  After this cutting, if the root part transport body 22 and the leaf tip part transport body 27 are simultaneously rotated about the rotation drive shaft toward the original position by a predetermined rotation angle, the long leek after the cutting process is performed. Even if the two leaf tip portions 2b are pulled back by the leaf tip portion return portion 29 of the leaf tip portion transport body 27, the two leaf tip portions 2b return to their original positions.

  Next, the operator grasps the leaf tip 2b that has been returned to its original position, lifts the long leek 2 in the left-right direction, and turns the long leek 2 90 degrees so that the leaf tip 2b is in front. After making it the front-back direction, it is mounted on the mounting body 30 of the skin peeling means 7 while holding the long onion 2 in the front-rear direction.

  That is, for example, as shown in FIG. 7, the worker grasps the leaf 2f located on the center side among the plurality of leaves (green portions) located open in a plane, and forms the elongated rod-like main body portion. 2e is inserted between both sandwiching bodies 34 and placed on the placing body 30.

  Then, the both clamping arms 41 are rotated in the separation direction against the urging force of the urging body 35, and thereby the both clamping plates are in a state of being opposed to each other with a distance corresponding to the thickness of the main body 2e. At 42, the main body 2e of the long onion 2 is clamped from both the left and right sides, and the front ends of the nozzle bodies 31 are positioned in the vicinity of the left and right sides of the clamped main body 2e.

  When the long onion detecting means 71 detects the long onion 2 inserted between the two nozzle bodies 31, the control means 72 controls the drive motor 33 based on this detection, and the open / close valve is opened from the closed state. Is switched to.

  Then, the rotating body 66 is rotated in one direction by driving of the drive motor 33 and the both interlocking bodies 67 are interlocked. As a result, the two nozzle bodies 31 are rotated at a predetermined rotation angle about the rotation center axis A in the vertical direction. With α, the high-pressure air is jetted toward the long onion 2 from the jet hole opened toward the front side while rotating back and forth synchronously in the left-right direction.

  In this state, as shown in FIG. 8, when the operator pulls the long onion 2 between the nozzle bodies 31 while holding the leaf 2f on the center side, the long onion 2 moves forward. The outer skin 2c of the long onion 2 is peeled off from the main body 2e together with the unnecessary leaves 2d on the left and right sides by the injection of high-pressure air from both nozzle bodies 31 that reciprocally rotate in the left-right direction. That is, the high-pressure air from both nozzle bodies 31 reciprocally turning in the left-right direction hits the vicinity of the base end of the unnecessary leaf 2d, and peels off the outer skin 2c from the main body 2e while opening the unnecessary leaf 2d on both sides. Blow away.

  When the operator inserts the long onion 2 after the skinning process from between both the sandwiching bodies 34, the long onion detecting means 71 does not detect the long onion 2, and control is performed based on the non-detection of the long onion detecting means 71. The means 72 controls the drive motor 33 to stop and switches the on-off valve from the open state to the closed state.

  Thus, the root cutting operation, leaf cutting operation and skinning operation for the long onion 2 are completed, and the operator repeats the above-described operation.

  And according to the said long leek processing apparatus 1, both the nozzle bodies 31 which make space | interval in plan view by separating and opposing each other right and left are horizontal with a predetermined rotation angle α about the rotation center axis A in the vertical direction. Since high-pressure air is jetted toward the long onion 2 while reciprocating in the left-right direction, for example, the outer skin 2c of the long onion 2 is efficiently peeled off as compared with the conventional configuration in which the jetting direction of the nozzle body is always constant. Therefore, the working efficiency can be improved.

  That is, in the conventional configuration in which the nozzle body injection direction is always constant, the high pressure air sprayed linearly from the nozzle body is concentrated on only one part of the long onion, so the outer skin is long green onion. It may not peel off well from the main body, and may not be efficiently peeled off. On the other hand, since the nozzle body 31 injects high-pressure air while reciprocating left and right as in the above-described long onion processing apparatus 1, in the configuration in which the injection direction of the nozzle body 31 varies, the high pressure from the nozzle body 31 Since air diffuses over a wide area and hits the outer skin 2c of the long onion 2, when the direction of the external force that attempts to peel the outer skin 2c from the main body 2e changes from inward to outward, the external force always keeps the outer skin 2c outward. It is opened and peeled away from the main body 2e without fail, so that the stripping work can be performed efficiently.

  In addition, even if the injection pressure of the nozzle body 31 is set to a pressure value lower than the conventional injection pressure, the high pressure air from the nozzle body 31 can be efficiently peeled off, so a small compressor 63 can be used. , Energy saving can be achieved.

  Further, the rotation drive means 32 includes a rotating body 66 that is common to both nozzle bodies 31, one interlocking body 67 that is connected to one of the nozzle bodies 31, and both nozzle bodies 31. And the other interlocking body 67 connected to the other nozzle body 31 of the above, for example, compared with a configuration provided with a rotation driving means for reciprocally turning both the left and right nozzle bodies 31 respectively. Thus, the configuration can be simplified and the manufacturing cost can be reduced.

  Furthermore, the long onion detecting means 71 for detecting the long onion 2 inserted between the two nozzle bodies 31 facing each other and the drive motor 33 of the rotation driving means 32 is driven based on the detection of the long onion detecting means 71. Since the control means 72 for controlling is provided, both the nozzle bodies 31 can be reciprocally rotated by the rotation drive means 32 only when desired, so that energy saving can be achieved.

  The onion processing apparatus 1 has been described with respect to a configuration including a pair of left and right nozzle bodies 31. For example, the long onion processing apparatus 1 includes a configuration including four nozzle bodies 31 in two pairs of left and right, and a pair of nozzle bodies 31. Further, a configuration in which a fixed nozzle is provided as an auxiliary may be used.

  Further, the rotation drive means 32 is not limited to one having a drive source such as the drive motor 33, and may be a manual rotation drive means for reciprocatingly rotating the nozzle body 31 by an operator's human power, for example.

  Further, for example, a configuration in which the predetermined rotation angle α of both nozzle bodies 31 can be adjusted within a predetermined range may be used.

  Further, for example, the switching means of the changeover switch can be selectively switched between a state in which both nozzle bodies 31 inject high pressure air while reciprocatingly rotating and a state in which both nozzle bodies 31 are stopped and inject high pressure air. The structure etc. which become may be sufficient.

  Further, for example, a long-onion processing apparatus dedicated to skin peeling which does not include the root part cutting means 5 and the leaf tip part cutting means 6 and performs only a skinning operation for peeling the outer skin 2c may be used.
