[Problems to be solved by the invention]
However, since the above-mentioned green onions are manually suspended one by one with respect to a suspending means such as a belt or a sandwiching plate and supplied to a peeling apparatus by approximately vertically, peeling of green onions having various lengths is performed. It is difficult to make the starting end almost the same height, and if the leek peeling starting end is higher than the nozzle outlet, some epidermis will remain on the stalk and unnecessary skin on the outer surface of the stalk will be cleaned. Cannot be stripped off. In addition, since the leaf side of the green onion is held by the hanging means, there is a problem that the suspended height of the green onion cannot be corrected during the transportation.

[0026]
FIG. 7 shows a control circuit block diagram of the crop peeling apparatus 1. The control apparatus 22 has a built-in CPU, ROM, and RAM, and the CPU controls the transfer conveyor 2 and the image pickup according to a program stored in the ROM. The camera 19, the image processing device 20, the address reading device 21, the holding unit 26, the support unit 27, the skinning unit 28, and the driving and stopping of the motors 35 a and 35 b are controlled. The CPU determines the boundary between the stem portion Ab and the leaf portion Ac of the green onion A (for the green onion A) based on image information output from the image processing device 20 (for example, information such as light and darkness, color scheme, reflected light, and transmitted light). The peeling start end Ad) is individually calculated, and the peeling start end Ad of the green onion A, which is started to be peeled off by the peeling device 25 described later, is comprehensively determined.
[0027]
As shown in FIG. 2, the above-mentioned imaging camera 19 is disposed on the upper part of the transport path in the trimming section b facing the outer peripheral surface of the boundary between the stem Ab and the leaf Ac of the green onion A placed on the mounting table 2a. And outputs a captured image of the boundary portion to the image processing device 20.
[0028]
The image processing device 20 described above binarizes image information between the stem Ab and the leaf Ac captured by the imaging camera 19 and outputs the binarized data to the control device 22. Further, the address reading device 21 arranged at the lower part of the transport path reads the address information set on the mounting table 2a itself or the address information set on the transport conveyor 2 corresponding to the mounting table 2a, and outputs the address information to the control device 22. .
[0029]
Further, as another example of the identification means instead of the address information, for example, a recording medium (for example, a barcode, an ID card, a magnetic card, or the like) attached to the mounting table 2a itself or attached to the transport conveyor 2 corresponding to the mounting table 2a. May be read, or information recorded in the control device 22 may be read in correspondence with the unique information of the recording medium.
[0030]
In addition, the CPU determines that the skinning unit 28 is substantially opposed to the skinning start end Ad of the green onion A with reference to the skinning start end Ad of the green onion A to which the air G discharged from the air discharging section 37 described later is first blown. Then, the moving distance until reaching the position to be moved is calculated, and the moving distance information is stored in the RAM in correspondence with the address information of the mounting table 2a read by the address reading device 21.
[0031]
When a predetermined number of the mounting tables 2a are moved to the skinning section c, the address information of the mounting tables 2a is individually read by the address reading device 21, and the number of the mounting tables 2a output from the address reading device 21 is changed. The moving distance information corresponding to the address information is read from the RAM, and the motor 35b described later is rotated forward and reverse based on the moving distance information, and the leek A held by the pair of holding bodies 26a is moved in a direction substantially orthogonal to the transport direction. I do.
[0032]
Further, based on the pulse signal output from the motor 35b, the moving amount of the skinning unit 28 is individually detected, and the detected moving amount information is compared with the moving amount information stored in the RAM in advance and calculated. I do. When it is determined that the movement amounts are substantially the same, the driving of the motor 35b is stopped, and the peeling unit 28 is stopped at an upper position substantially opposed to the peeling start end Ad of the green onion A, as shown in FIG. I do. If it is determined that the movement amounts are different, the motor 35b rotates forward and backward until the movement amount information matches. Further, the cutting information stored in the RAM is deleted or overwritten when returning from the end to the start.
[0033]
The illustrated embodiment is configured as described above, and the operation of peeling green onion A by the crop peeling apparatus 1 will be described below.
[0034]
First, as shown in FIG. 1, leek A is placed one by one on a mounting table 2a. By pressing the tip of the root portion Aa against an alignment portion (not shown) such as a belt or a plate, for example, while projecting a predetermined length (for example, approximately 3 cm) to the left side of the mounting table 3 with respect to the transport direction. Is supplied to the trimming device 5 in the trimming section b.
[0035]
Next, the root Aa side of the leek A is cut by a predetermined amount by the root cutting device 8 of the trimming device 5, the leaf Ac side of the leek A is cut by a predetermined amount by the leaf cutting device 9, and the skinning section c Is continuously supplied to the peeling device 25 of FIG.
[0036]
Further, as shown in FIG. 2, a boundary portion between the stem portion Ab and the leaf portion Ac of the green onion A mounted on the mounting table 2 a is imaged by the imaging camera 19, and the image information is binarized by the image processing device 20. And outputs it to the control device 22. The control device 22 individually determines the peeling start end portion Ad of the leek A based on the image information output from the image processing device 20, and the peeling unit 28 reaches the peeling start end Ad of the leek A. The moving distance is calculated, and the moving distance information and the address information of the mounting table 2a read by the address reading device 21 are stored in the RAM in association with each other.
[0037]
Next, as shown in FIGS. 3 and 4, in the peeling section c, the units 26, 27, and 28 are substantially synchronized with a predetermined number of leeks A.. The holding unit 26 is independently driven while being moved only in the transport direction, the leaf Ac of the green onion A protruding to the right side of the mounting table 2a is held and lifted by the pair of holding bodies 26a, and the root Aa side is supported by the support unit 27. The support 27a lifts to a predetermined height and is supported substantially horizontally.
[0038]
In addition, the control device 22 reads the moving distance information corresponding to the address information of the mounting table 2a read by the address reading device 21 from the RAM, and based on the moving distance information, moves the peeling unit 28 substantially orthogonally to the transport direction. It is moved independently in the direction, and as shown in FIG. 8, stops at the upper position substantially opposite to the peeling start end Ad of the green onion A.
[0039]
Subsequently, as shown in FIGS. 5 and 6, the peeling unit 28 is independently driven to correct the bent portion of the stem Ab by the support arms 36, 36, and the air discharged from the air discharge unit 37 is corrected. G is sprayed substantially evenly on the outer peripheral surface of the stem Ab corresponding to the peeling start end Ad of the green onion A, and the unnecessary epidermis Ae of the green onion A is peeled off and separated at a stroke toward the root Aa side.
[0040]
Immediately before reaching the root Aa side, the support 27a is temporarily lowered to hold the root Aa side of the green onion A in a hanging state. When the skinning unit 28 is removed from the root Aa, the support 27a is raised again and supported. If the epidermis Ae hangs at the lower end of the root Aa, for example, it is pulled by a pair of separation rolls, pulled by a holding means such as a chuck or an arm, or sucked by a suction means such as an intake blower or a vacuum pump. May be separated and removed.
[0041]
Subsequently, after the peeling unit 28 is moved to the left side of the transport path, the holding by the pair of holders 26a is released, the support 27a is lowered to the standby position, and the peeled green onion A is placed on the mounting table 2a. Place it again. Thereafter, the root Aa of the green onion A placed on the mounting table 2a is brought into contact with or pressed against the alignment belt 43 in the collection section e, and is aligned substantially straight in the transport direction in the next step (for example, a sorting step or box packing). Process). Hereinafter, in the same manner as described above, the onion A trimming work, the aligning work, and the peeling work are continuously performed.
[0042]
As described above, the peeling unit 28 of the peeling device 25 is independently moved to a position substantially opposite to the peeling start end Ad of the green onions A ... conveyed by the conveyor 2, and the skin Ae of the green onions A is moved. Since peeling starts from the peeling start end Ad, even if the peeling start end Ad of the green onion A is irregular and irregular, even if it has various lengths, the skin Ae of the green onion A is surely and securely. It can be peeled off neatly.
[0043]
In addition, the labor and work of aligning the peeling start portion Ad of the green onion A with the operator's hand or mechanically aligning it can be omitted, and labor and efficiency of the peeling operation can be reduced. Since it is not necessary to move the peeling start end Ad to a position facing the peeling unit 28, the commercial value of the green onion A is not impaired and a fresh state can be maintained.
[0044]
In addition, since the peeling unit 28 is reciprocated in the transport direction substantially in synchronization with the transport speed of the transport conveyor 2 and the skin Ae of the green onion A transported by the transport conveyor 2 is continuously peeled off, the intermittent movement is performed. In comparison with the method, the number of the peeling units 28 to be installed is reduced, and the transport distance of the entire apparatus is shortened, so that the installation and layout can be easily performed, and the transport line from the trimming process to the sorting process is reduced It can be configured as one.
[0045]
Note that the configuration of the crop peeling apparatus 1 described above can be applied to, for example, an operation of peeling the skin Ae of the green onion A held in a substantially vertical posture and a substantially oblique posture.
[0046]
As shown in another example of FIG. 9, the mounting table 2 a of the transport conveyor 2 constituting the crop peeling apparatus 1 is moved around the transport direction substantially intermittently and the leek by the transport conveyor 2 is used. In substantially synchronism with the intermittent feeding operation of A, the units 26, 27, and 28 constituting the peeling device 25 are intermittently moved in the transport direction while being substantially opposed to the leek A transported by the transport conveyor 2. The skin Ae of the green onion A can also be peeled off.
