[0013]

FIG. 1 shows a flow chart of an embodiment of a processing method according to the present invention, in which a peeling step 1 and an inspection step 2 are performed.
And a weighing step 3, and a bundling step 4 and a box packing step 5. While green onions such as universal onions are transported, they can be shipped through these steps.

The peeling step 1 is to peel the skin near the root of the green onion from its upper part. When peeling,
The green onion is transported in a horizontal state, and compressed air is blown on the green onion, and the skin is peeled off by the pressure of the compressed air.
Therefore, manual peeling is not required. In addition, the spray of the compressed air removes adhering mud and cleans, thereby improving the appearance.

In the inspection step 2, the length of the green onion conveyed in the horizontal state is determined, and the green onion deviating from a predetermined length is removed from the conveying path to adjust the length. Although this inspection is performed visually, the length can be reliably determined because the level mark is used as a reference as described later. In this case, the appearance of the onion may be visually inspected at the same time, and the quality can be improved and the uniformity can be improved by removing the onion having many withered portions, the fading leek, and the like.

In the weighing step 3, the weight of the green onion is measured in order to bundle the green onion in a fixed amount. In this measuring step 3, since the green onions are conveyed while being conveyed in a horizontal state, continuous measurement is possible.

The bundling step 4 is to improve the handleability and bind the green onions weighed so as to have a predetermined weight and bundle them. This bundling step is performed by winding a label made of a plastic sheet around leek.

FIGS. 2 to 5 show a first and second horizontal transfer devices 10 and 15 and a peeling device 20 arranged between the horizontal transfer devices 10 and 15, respectively.
And Reference numeral 11 denotes a table provided on the upstream side of the first horizontal transfer device 10, on which harvested leek is loaded. The mounting table 11 has a tilt adjusting screw 12 on the lower surface, and the first horizontal transfer device 10
Incline so that the side is lower. This facilitates introduction of green onions from the table 11.

Each of the first and second horizontal conveying devices 10 and 15 conveys leeks one by one in a horizontal state. For this purpose, the first horizontal transfer device 10 is provided with a transfer conveyor 13 stretched horizontally. The conveyor 13 is formed of a high friction material 13a such as artificial turf, sponge or the like at a portion indicated by a chain line hatching in FIG.
3 and is conveyed downstream in a horizontal state.

The second transfer device 15 is horizontally extended and has a pair of upper and lower transfer conveyors 16 and 17 (see FIG. 3). The conveyors 16 and 17
Is received in a state where the green onion that has passed through the peeling device 20 is sandwiched, and is conveyed downstream. The conveyors 16 and 17 do not sandwich the entire length of the leek, but transport about 60 mm from the root portion in the length direction of the leek, and the other parts of the leek are in a floating state. . In order to prevent the leeks from falling off during this partial clamping, these conveyors 16 and 17 have a high friction material 16a (17a is omitted) such as artificial turf and sponge, as shown by the chain line hatching in FIG.
Is partially used. As shown in FIG. 3, the transporting conveyor 17 is stretched in a triangle shape in which the peeling device 20 is partially lowered.
Leek that has passed through 0 is received at this lowered portion. Since the first and second horizontal transport devices 10 and 15 transport the leek in a horizontal state, the leek can be transported stably without falling off.

FIGS. 4 and 5 show the internal structure of the peeling apparatus 20. FIG. The high-friction material 13a of the transport conveyor 13 of the first horizontal transport device 10 has entered the peeling device 20. Further, the sandwiching conveyor 14 facing the high friction material 13a is running inside (see FIG. 3). The sandwich conveyor 14 is made of the same material as the high friction material 13a of the conveyor 13 and sandwiches the middle portion of the green onion A with the high friction material 13a. As a result, a transport path for the green onion A is formed, and the green onion A is moved by a horizontal bear in the peeling apparatus 20 while the other part such as the root is floating.
Move book by book.

A plurality of injection nozzles 21, 22, 23 are arranged on the conveyance path of the leek A. These injection nozzles 21, 22, and 23 blow compressed air onto green onions, and the outlets thereof are directed toward the root of green onion A. Further, as shown in FIG. 5, the injection nozzles 22 and 23 are arranged so as to blow compressed air from both upper and lower sides to the green onion conveyed in a horizontal state.
The plurality of spray nozzles are arranged in order along the length of the green onion A from the upstream side to the downstream side in the transport direction of the green onion A. In the illustrated example, the injection nozzle 21 → the injection nozzle 22 → the injection nozzle 23 are arranged in the length direction of the onion A in this order, the injection nozzle 21 is farthest from the root, and the injection nozzle 23 is closest to the root. In such an arrangement, the compressed air is jetted close to the root with the transport of the leek A, so that the skin is peeled off without a break and thus can be reliably peeled. In addition, each of the injection nozzles located above the transport path is attached to a height adjusting plate 24, and the height adjusting plate 24 is
5, the height adjustment according to the size of the green onion is performed.

The peeling apparatus 20 as described above has a structure for preventing noise when blowing compressed air. That is, as shown in FIG. 4, the whole is covered by the housing 26, and the inside of the housing 26 is divided into a skin storage chamber 27 and a plurality of sound deadening chambers 26a, 26b, 26c. The compressed air from the injection nozzle gradually diffuses by moving inside the housing 26 in the order of the skin storage chamber 27 → the sound deadening chamber 26a → the sound deadening chamber 26b → the sound deadening chamber 26c.
Noise can be reduced. In this case, leather storage room 2
Numeral 7 indicates that the skin peeled off from the green onion A falls and accumulates.

Since the peeling apparatus 20 peels the skin by blowing compressed air from the injection nozzles 21, 22, 23 while transporting the green onion A in the horizontal direction, the peeling by hand is not required, and a large labor is saved. Can be In addition, since the leek is transported in a horizontal state, the leek can be prevented from falling off, and the skin can be reliably peeled.

The green onions that have passed through the peeling device 20 are transported by the second horizontal transport device 15 and introduced into the inspection device 30. In FIGS. 2 and 3, reference numeral 18 denotes an auxiliary nozzle arranged in the second horizontal transfer device 15. The auxiliary nozzle 18 jets compressed air toward the green onion from between the conveyors 16 and 17 of the second horizontal conveyor 15. The compressed air from the auxiliary nozzle 18 flows from the root of the leek conveyed in a horizontal state along the top direction, thereby removing the leaves attached to the leek. For this reason, green onions can be cleaned.

FIGS. 6 and 7 show the inspection device 30. FIG. In this inspection device 30, a conveyor belt 32 is supported in a horizontal state by a footrest 31, and conveys green onions in a horizontal state. The conveyor belt 32 travels endlessly and conveys leek by transmitting rotational force from a power box 33 having a motor (not shown) to a pulley 34. The conveyor belt 32 transports the leek in a horizontal state and determines the length of the leek during the transportation. For this reason, the conveyor belt 32 has a plurality of level marks 32a, 32b,
32c is applied.

A plurality of level marks 32a, 32b, 32
c has different coloring from each other, and serves as an index for determining the length of the green onion in three or more stages. That is, the onion extending to the level mark 32a is determined as L size, the length of the area of the level mark 32b is determined as M size, and the length of the level mark 32c is determined as S size. This allows the operator to extract the green onion that does not match the predetermined size to be processed, so that the size of the green onion can be made uniform. In addition to this determination, the operator can visually detect the properties of green onions such as thickness, color fading, and leaf blight, and remove defective products.

Therefore, since the length of the inspection device 30 can be determined while transporting the green onion, the inspection of the green onion can be performed quickly and easily, and the work efficiency is improved. In this embodiment, a plurality of color belts colored differently may be used as a level mark and a transport belt. In this case, there is an advantage that the length reference to be determined can be freely selected by changing the arrangement position of the color belt. Reference numeral 35 denotes an accumulation box provided at the transport end of the inspection device 30, and the transported leek falls and is stored. The operator takes out the green onion from the accumulation box 35 and transfers it to the weighing device 40.

In this case, the weighing mechanism 41 and the input mechanism 43 are arranged on the same line in the transport direction of the leek, but the pickup mechanism 42
Are arranged at positions deviated from these, in the illustrated example, at positions at the back of these. The weighing mechanism 41 weighs the leek after inspection until it reaches a predetermined weight.
Is a weighing mechanism 4 for weighing leek that is less than a predetermined weight and near a predetermined weight.
The charging mechanism 43 is for charging the insufficient green onion into the receiving cup 46. Hereinafter, each mechanism will be specifically described.

As shown in FIG. 8, the weighing mechanism 41 includes four weighing machines 45 attached to two base tables 44, respectively.
And an openable / closable V-shaped receiving cup 46 attached to the tip of each weighing machine 45 and a switch 47 for opening and closing the receiving cup 46. The weighing mechanism 41 weighs the weight of the green onion put into each receiving cup 46 until the weighing machine 45 reaches a predetermined weight. When the weight reaches a predetermined value, the weighing machine 45 outputs a signal to the switch 47 so that the switch 47 opens each receiving cup 46. Below each receiving cup 46, a bucket 61 of a transfer device 60 described later is provided.
Are stopped in a stopped state, and when the receiving cup 46 is opened, the green onion weighed to a predetermined weight falls into each bucket 61. Accordingly, the transfer device transfers the leek weighed to a predetermined weight as one unit and transfers the leek of each unit to a bundling device described later.

The pickup mechanism 42 is provided with the weighing mechanism 41.
The leek having a weight less than the predetermined weight and around the predetermined weight is put into the receiving cup 46. The pickup mechanism 42 is disposed on the back side of the weighing mechanism 41. 9 and 10 show the pickup mechanism 42.

The pick-up mechanism 42 is a chain 49 endlessly wound around a sprocket 48 which is driven to rotate.
And a bucket 50 attached to the chain 49 at predetermined intervals. This transport member transports the leek A by the bucket 50 moving. In this case, since the onion is weighed at two units at a time, the bucket 50 intermittently moves with two buckets as one stroke so as to synchronize with the unit.

The pickup mechanism 42 is located at the transport end of the transport member. The pickup mechanism 42 is a moving body 53 mounted on a frame 52 so as to be vertically movable.
(See FIG. 10) and the two

As shown in FIG. 9, the moving body 53 includes a slide frame 53a extending in a direction parallel to the bucket 50. The slide frame 53a is connected to a driving source (not shown) and reciprocates in the length direction of the bucket 50. I do. Thereby, the moving body 53 advances and retreats in the same direction, that is, the direction of the arrow in FIG. 9, and moves on the receiving cup 46 of the weighing mechanism 41 by advancing in that direction.

A switch 55 is attached to the moving body 53, and two pickups 54 are connected to the switch 55. The pickups 54 are opened and closed by the operation of the switch 55. As shown in FIG. 8, each pick-up body 54 is formed in a substantially oval shape, and holds the leek conveyed by the bucket 50 by opening and closing the pick-up body 54 and drops the leek held in the receiving cup 46 of the weighing mechanism 41. I do.

As shown in FIGS. 8 and 11, the loading mechanism 43 is provided with upper and lower loading conveyors 58 and 57.
The input conveyors 58 and 57 are shifted along the transport direction of the green onion, so that their end positions are different. The lower input conveyor 57 faces the receiving cup 46 at the front of the weighing mechanism 41, and the upper conveyor 58 is at the rear. Facing the receiving cup 46. Each of the charging conveyors 57 and 58 transports the inspected leek A one by one and puts it into the corresponding receiving cup 46, whereby the green onion is replenished for the lack of weight. In this case, the height position of the upper feeding conveyor 58 is set so as to avoid interference when the moving table 53 of the pickup mechanism 42 advances.

The operation of the weighing device 40 will be described. After the inspection, the green onions accumulated in the accumulation box 35 are transferred to the bucket 50 of the pickup mechanism 42 by the operator, and the charging conveyors 57,
58 are placed one by one. A predetermined weight (for example, 100 g) is applied to the bucket 50 of the pickup mechanism 42.
Less than a predetermined weight (for example, 80 to 90).
Transfer the green onion of g). The pickup mechanism 42 transports the green onion A with a stroke corresponding to two buckets. The moving body 53 stands by at this transport end position in a slightly elevated state, and the two buckets 50
When it is located below 4, it descends. At this time, leek A
As shown in FIG. 9, the one end is set to extend beyond the end of the bucket 50, and the moving body 53 is lowered in the open state of the big up body 54, and the pickup body 54 is opened at the lower end. I do.

As a result, each pickup body 54 has a green onion A
The moving body 53 advances toward the weighing mechanism 41 in this state. Then, the pick-up bodies 54 are opened, and the green onions A, each of which has been grasped, are received by the receiving cup 4 of the weighing mechanism 41.
Put into 6. At the time of loading of green onions from the pickup body 54, the weight is insufficient, and each charging conveyor 5
7 and 58 feed the leek A into the receiving cup 46 one by one by the traveling. As a result, when a predetermined weight is reached,
The weighing device 45 of the weighing mechanism 41 detects the signal, and the switch 47 thereof opens the receiving cup 46, and the transfer device 6 that is waiting below
A predetermined weight of green onion is dropped into the zero bucket 61.

Since such a weighing device 40 starts measuring green onions from a weight near a predetermined weight, the weighing device 40 can reach the predetermined weight in a short time and can measure quickly.
In the illustrated example, since the weight of the green onion is measured by two units, parallel weighing can be performed, and the processing amount further increases.

FIGS. 12 and 13 show a transfer device 60 for transferring leek weighed to a predetermined weight as a unit and a bundling device 70 for bundling one unit of weighed leek. Transfer device 6

When the label 5 is extended, the suction pads 76 suck the lower end portions of the labels in the respective label stockers 77 and take out the labels one by one.

In this embodiment, a label 90 is used in which a transparent plastic sheet is subjected to predetermined printing such as a product name and a place of production. This label 90 is attached to the suction pad 76.
When the suction cylinder 75 is shortened after the suction, the upper arm 8 is partially broken by the leek B from above.
1 moves to the left, comes to the top of the green onion B, and descends. At this time, both end portions are in a state of hanging from the green onion B.

The slider 73 is located between the upper chuck 71a and the lower chuck 71b. The slider 73 is provided at a position corresponding to a label 90 hanging down from the leek B, and pushers 78 that come into contact with the label 90 are attached to two places on the upper surface. Each pusher 78 is provided corresponding to each chuck member 71. The slider 73 is connected to a slide cylinder 79. When the cylinder 79 operates, the slider 73 reciprocates left and right, and when the slider 73 slides to the right, the pusher 78 comes into contact with the label 90 so that one of the labels 90 is moved. It works so that the end portion is along the outer peripheral surface of the leek.

The discharge member 74 is constituted by the upper arm 81 and the lower arm 82 facing each other. These arms 81, 82 have arc-shaped concave portions 81a, 82a.
Are formed at two opposing positions in the longitudinal direction. The onion B is sandwiched between the opposing concave portions 81a and 82a, and the leek B is discharged from the chuck member 71. In the present embodiment, the concave portion 82a of the lower arm 82, in addition to this discharge, also acts to cause the other end of the label 90 to follow the outer circumference of the spring onion B, as will be described later. The upper arm 81 and the lower arm 82 described above are attached to the guide members 83 and 84, and advance and retreat toward the chuck member 71 by the operation of the guide members 83 and 84.
