Description

【0001】
【発明の属する技術分野】
本発明は、野菜や果物などの被選別物を搬送体に載せて搬送し、等級別に配置した排出ゲートにおいて被選別物を排出することにより等級選別する搬送選別機に関し、特に鍵盤状に配列した搬送支持片を傾動させて被選別物を排出する排出装置に関する。
【0002】
【発明が解決しようとする課題】
従来、鍵盤状に配列した搬送支持片を傾動させて被選別物を排出する排出装置は、各排出ゲートに一定の幅を持った直動式のソレノイドを1台設置し、一度に被選別物の長さ分の片数の搬送支持片を傾動して被選別物を排出していた。
ところが、この方式は動作部の質量が大きいため、速度が遅く、処理能力が低いという問題があった。
【0003】
そこで、動作部の質量を小さくするため、ソレノイドを小型にして一度に傾動する搬送支持片を1片とし、このソレノイドを通過する被選別物の長さ分の片数の搬送支持片を次々に傾動して被選別物を排出する方式に改めた。
ところが、この方式は搬送支持片を順次傾動して排出するため、被選別物が斜めに落下して人参などの場合は先端の細い部分が折れるという問題があった。
【0004】
そこで本発明は、鍵盤状に配列した搬送支持片を次々に傾動して被選別物を排出するとき、搬送支持片を傾動する順序を工夫して被選別物が斜めに落下しないようにすることを目的とする。
【0005】
【課題を解決するための手段】
かかる目的を達成するために、本発明は以下のように構成した。
【0006】
すなわち、個々に独立して傾動可能な四片以上の搬送支持片(6)を鍵盤状に配列した搬送ユニット(5)で被選別物を支持して搬送し、所定の排出ゲート(9)で前記搬送支持片(6)を傾動手段(A)(B)で傾動して被選別物を排出する搬送選別機の排出装置であって、
前記搬送支持片(6)は偶数片備え、
前記傾動手段(A)(B)は、所定の数の搬送支持片(6)分の幅を隔てて二ヶ所設けられると共に、同時に作動して前記搬送支持片(6)を同時に二片傾動するものであり、
この傾動手段(A)(B)を複数箇所に設け、
前記搬送ユニット(5)を順次移動させて、前記傾動手段(A)(B)で前記搬送支持片(6)を同時に二片傾動させる動作を順次行い、搬送支持片(6)を全て傾動させることにより、被選別物が前記排出ゲート(9)に排出される構成とすることを特徴とする搬送選別機の排出装置である。
【0007】
【発明の実施の形態】
以下に図面を参照して本発明の実施の形態について説明する。
【0008】
図1と図2に、本発明を実施した搬送選別機の側面図と平面図を示す。
搬送選別機1は、モータ2で原軸側プーリ3aを駆動し、原軸側プーリ3aと従軸側プーリ3bに2本の搬送チェーン4を平行に掛け渡す。
2本の搬送チェーン4は、間に複数のピン(図示しない)を差し込んで連結し、このピンで搬送チェーン4の間に等間隔に挿入する複数の搬送ユニット5を支持する。
搬送ユニット5の先端には、図3に示すように、複数の搬送支持片6を等間隔に鍵盤状に配列する。
【0009】
搬送選別機1の搬送上手には、野菜や果物などの被選別物をカメラで撮影し、画像解析して等級選別するコンピュータなどで構成する選別部7と、被選別物を搬送選別機1に供給する供給部8を配置する。
搬送選別機1の搬送経路には、等級別に配置した複数の排出ゲート9を設け、選別部7のコンピュータからの指令により、指定の排出ゲート9において被選別物を搬送支持する複数の搬送支持片6を順次傾動して落下させる。
排出された被選別物は、排出ゲート9下方に設置した搬送選別機1に直交する引き出しコンベア10に落下させて搬出する。
【0010】
排出ゲート9は、傾動手段としてのロータリーソレノイド11を被選別物の長さに応じてA、B2箇所に配置する。
A、Bの間隔は被選別物の長さの略半分のピッチに設定し、通過する搬送支持片6をA、B2箇所で同時に傾動する。
【0011】
図4に、搬送支持片6の側面図を示す。
搬送支持片6は、軸6aを搬送ユニット5の軸受5aに軸支して片持ち支持し、ピン6bをフック12に係止して水平姿勢を維持する。
フック12は、軸12aを搬送ユニット5の軸受5bに軸支し、コイルスプリング13でピン6b方向に付勢する
【0012】
搬送支持片6を傾斜するときは、フック12のレバー12bを押圧してピン6bを外し、軸6aに取り付けたトルクスプリング(図示しない)で先端を下方に付勢する。
傾斜した搬送支持片6は、下部のストッパ6cを搬送ユニット5のストッパ受け5cに当接する。
【0013】
本発明を実施した搬送選別機の排出装置は以上のような構成で、各排出ゲート9のA、B2箇所に配置したロータリーソレノイド11を同時に作動して通過する搬送支持片6のレバー12bを押圧してフック12を外し、通過する被選別物の長さ分の個数の搬送支持片6を次々に傾斜させて被選別物を排出する。
このとき、通過する被選別物の長さ分の個数の搬送支持片6を同時に傾斜させて被選別物を排出してもよい。
【0014】
図5に、搬送支持片6を傾斜させる順序を図示する。
例えば(a)に示すように、6片▲1▼、▲2▼、▲3▼、▲4▼、▲5▼、▲6▼で被選別物aを支持して矢印の方向に搬送するとき、以下の順序で各搬送支持片6を傾斜させる。
まず、(b)に示すように、最初にA、Bを通過する▲1▼、▲4▼を傾斜させる。
このとき、被選別物aは▲2▼、▲3▼、▲5▼、▲6▼に支えられて水平姿勢を維持する。
次に、(c)に示すように、次にA、Bを通過する▲2▼、▲5▼を傾斜させる。
このとき、被選別物aは▲3▼、▲6▼に支えられてなおも水平姿勢を維持する。
さらに、(d)に示すように、最後にA、Bを通過する▲3▼、▲6▼を傾斜させる。この段階で被選別物aを支持するすべての搬送支持片6が傾斜し、被選別物aは水平姿勢を維持したまま落下する。
【0015】
次に、本発明に関連して、搬送経路に隙間を設けて人参の黒点を検出する黒点検出装置について説明する。
この黒点検出装置は、図6に示すように、人参aを1列にして搬送する山形ベルト14の一端と、人参aを選別する鍵盤式の選別ベルト15の一端を乗り継ぎベルト16で接続し、この乗り継ぎベルト16を隙間をあけて前後に2分割し、この分割部17の上方にカメラ18を、下方にミラー19をそれぞれ配置する。
【0016】
ミラー19は、図7に示すように、人参aの搬送方向の左右両側に、斜め上向きのミラー19A,19Bを対向して設置し、カメラ18に対して人参aの左右の斜め下方の写像を投影する。
【0017】
この黒点検出装置は以上のような構成で、分割部17において、人参aの上面とミラー19A,19Bに写る人参aの左右の斜め下方側面をカメラ18で一度に撮影する。
また、カメラ18は上から下に向けて一方向だけを撮影し、横方向の背景を撮影しないので、画像に雑音が入らず、画像解析が容易になる。
さらに、乗り継ぎベルト16の分割部17において、人参aと共に搬送されてきたごみが落下してカメラ18に撮影されないので、この場合も画像に雑音が入らず、好都合である。
【0018】
【発明の効果】
以上のように、本発明では、鍵盤状に配列した搬送支持片を4片以上の偶数片にし、
傾動手段を所定の数の搬送支持片分の幅離間した2片の搬送支持片を同時に傾動するものとし、
この傾動手段を複数箇所に設け、傾動手段を順次作動して被選別物を排出する。
従って、本発明によれば、従来のように落下直前の被選別物を1片の搬送支持片で支えるのでなく、所定間隔離間した2片の搬送支持片で支えて落下させるので、被選別物が傾いて斜めに落下するようなことがなくなり、人参などの先端が先き折れするという問題が解消される。

The two transport chains 4 are connected by inserting a plurality of pins (not shown) therebetween, and support a plurality of transport units 5 inserted between the transport chains 4 at equal intervals.
As shown in FIG. 3, a plurality of transport support pieces 6 are arranged in a keyboard shape at equal intervals at the tip of the transport unit 5.
[0009]
As for the conveyance of the sorting machine 1, the sorting unit 7 composed of a computer or the like that takes a picture of the sorting object such as vegetables and fruits with a camera, analyzes the image, and sorts the grade, and the sorting object to the sorting machine 1. The supply part 8 to supply is arrange | positioned.
The transport path of the transport sorter 1 is provided with a plurality of discharge gates 9 arranged according to grades, and a plurality of transport support pieces for transporting and supporting the objects to be sorted in the designated discharge gate 9 according to a command from the computer of the sorting unit 7. 6 is sequentially tilted and dropped.
The discharged objects to be sorted are dropped onto a drawer conveyor 10 orthogonal to the transport sorter 1 installed below the discharge gate 9 and are carried out.
[0010]
The discharge gate 9 arranges rotary solenoids 11 as tilting means at two locations A and B according to the length of the object to be sorted.
The interval between A and B is set to a pitch that is approximately half the length of the object to be sorted, and the transport support piece 6 that passes therethrough is simultaneously tilted at the A and B positions.
[0011]
In FIG. 4, the side view of the conveyance support piece 6 is shown.
The conveyance support piece 6 supports the shaft 6a on the bearing 5a of the conveyance unit 5 to support it in a cantilever manner, and the pin 6b is locked to the hook 12 to maintain a horizontal posture.
The hook 12 pivotally supports the shaft 12a on the bearing 5b of the transport unit 5, and is urged by the coil spring 13 toward the pin 6b.
When the conveyance support piece 6 is inclined, the lever 12b of the hook 12 is pressed to remove the pin 6b, and the tip is urged downward by a torque spring (not shown) attached to the shaft 6a.
The inclined conveyance support piece 6 abuts the lower stopper 6 c on the stopper receiver 5 c of the conveyance unit 5.
[0013]
The discharge device of the transport sorter embodying the present invention is configured as described above, and simultaneously presses the lever 12b of the transport support piece 6 that passes through the rotary solenoids 11 disposed at the two locations A and B of the discharge gates 9. Then, the hooks 12 are removed, and the conveying support pieces 6 corresponding to the length of the passing object to be passed are inclined one after another to discharge the object to be selected.
At this time, the objects to be sorted may be discharged by simultaneously inclining the conveyance support pieces 6 as many as the length of the objects to be sorted passing therethrough.
[0014]
FIG. 5 illustrates the order in which the transport support pieces 6 are inclined.
For example, as shown in (a), when the object to be sorted a is supported by six pieces (1), (2), (3), (4), (5), and (6) and conveyed in the direction of the arrow. Each conveyance support piece 6 is inclined in the following order.
First, as shown in (b), (1) and (4) that first pass through A and B are inclined.
At this time, the object to be sorted a is maintained in a horizontal posture supported by (2), (3), (5), and (6).
Next, as shown in (c), (2) and (5) passing through A and B are inclined.
At this time, the object to be sorted a is maintained in the horizontal posture while being supported by (3) and (6).
Furthermore, as shown in (d), (3) and (6) that finally pass through A and B are inclined. At this stage, all the conveyance support pieces 6 supporting the object to be sorted a are inclined, and the object to be sorted a falls while maintaining the horizontal posture.
[0015]
Next, in relation to the present invention, a black spot detecting device for detecting a carrot black spot by providing a gap in the conveyance path will be described.
As shown in FIG. 6, this sunspot detecting device connects one end of a chevron belt 14 that conveys carrots a in a row and one end of a keyboard-type sorting belt 15 that sorts carrots a by a connecting belt 16. The connecting belt 16 is divided into two front and rear portions with a gap, and a camera 18 and a mirror 19 are arranged above the dividing portion 17 and below, respectively.
[0016]
As shown in FIG. 7, the mirror 19 is provided with diagonally upward mirrors 19 </ b> A and 19 </ b> B facing the left and right sides in the conveyance direction of the carrot a, so Project.
[0017]
This black spot detecting device is configured as described above, and the dividing unit 17 captures the upper surface of the carrot a and the diagonally lower side surfaces of the left and right of the carrot a captured in the mirrors 19A and 19B with the camera 18.
In addition, since the camera 18 captures only one direction from the top to the bottom and does not capture the background in the horizontal direction, the image does not contain noise and image analysis is facilitated.
Furthermore, since the garbage conveyed with the carrot a falls in the dividing part 17 of the connecting belt 16 and is not photographed by the camera 18, this case is also convenient because there is no noise in the image.
[0018]
【The invention's effect】
As described above, in the present invention, the conveyance support pieces arranged in a keyboard shape are made into an even number of four or more pieces,
The tilting means tilts two transport support pieces spaced apart by a predetermined number of transport support pieces simultaneously,
This tilting means is provided at a plurality of locations, and the tilting means is sequentially operated to discharge the objects to be sorted.
Therefore, according to the present invention, since the object to be sorted just before dropping is not supported by a single conveying support piece as in the prior art, it is dropped by being supported by two conveying support pieces spaced apart by a predetermined distance . The problem that the tip of a carrot or the like breaks first is eliminated.
