The

前記取付ブラケット2は、略箱型状に形成されて、この底辺部を前記搬送チエン1のリンクプレート部にリンクピン18で締め付けて取付ける。取付ブラケット2の内側には上下一対の平行リンク3をリンクピン23周りに上下回動自在に設け、この平行リンク3の後端にリンクヒッチ24をリンクピン25で枢支する。このリンクヒッチ24の後側にプレート形態の支持アーム5をアーム軸4の周りに左右回動自在にして取付ける。このアーム軸4は前記搬送チエン1のリンクピン18の移動軌跡延長線上にあって、チエン幅の略中央部上に沿って設けられる。この支持アーム5は、左右一側部に外側へ転倒回動可能の選別皿6を転倒ピン26で枢支し、左右両側端部にはスライダ7、8を形成し、該取付ブラケット2の後側に突出のピンローラ27を嵌合案内する円弧状の案内穴28を形成する。この案内穴28の一側端には係合突部29を形成して、該ピンローラ27を係合させることによって、支持アーム5の搬送姿勢Aを維持する構成としている。この案内穴28の高さは、ピンローラ27の径よりも適宜に大きく形成されて、平行リンク3を介する支持アーム5の遊動を行わせることができると共に、該係合突部29がピンローラ27を越えて回動係合されることによって、支持アーム5の搬送姿勢Aを安定して維持させることができる。又、この支持アーム5が一側へ回動されて、ピンローラ27に対して案内穴28の係合突部29とは反対側の端が係止されると、この支持アーム5の回動作用によって選別皿6が転倒ピン26の周りに反転されて排出姿勢Bとなる。前記スライダ7、8は、支持アーム5が搬送姿勢Aにあるとき外側端下がりの傾斜縁30を形成し、この外側端部にガイドレール10、11上面や、転倒ガイド12面に摺動する摺接縁31が形成される。この摺接縁31は、これらガイドレール10、11や転倒ガイド12に掬い上げられ易い形態にソリ状傾斜縁に形成される。支持アーム5の上部には、選別皿6を水平姿勢に受けるストッパ32を設けて、選別皿6底のストッパ33を受け止めることができる。又、前記転倒ピン26回りの選別皿6の転倒位置を係止するためのストッパ34、35が、この転倒ピン26を支持する支持アーム5側と選別皿6部との間に形成される。  The mounting bracket 2 is formed in a substantially box shape, and the bottom side portion is fastened and attached to the link plate portion of the transport chain 1 by a link pin 18. A pair of upper and lower parallel links 3 are provided inside the mounting bracket 2 so as to be rotatable up and down around the link pin 23, and a link hitch 24 is pivotally supported by a link pin 25 at the rear end of the parallel link 3. A support arm 5 in the form of a plate is attached to the rear side of the link hitch 24 so as to be rotatable around the arm shaft 4. The arm shaft 4 is on the extension line of the movement path of the link pin 18 of the transport chain 1 and is provided along the substantially central portion of the chain width. This support arm 5 pivotally supports a sorting pan 6 that can be turned to the outside on one side of the left and right with a tipping pin 26, and has sliders 7 and 8 formed on both left and right ends. An arcuate guide hole 28 for fitting and guiding the protruding pin roller 27 is formed on the side. An engaging projection 29 is formed at one end of the guide hole 28 and the pin roller 27 is engaged to maintain the conveying posture A of the support arm 5. The height of the guide hole 28 is formed to be appropriately larger than the diameter of the pin roller 27 so that the support arm 5 can move freely through the parallel link 3, and the engaging protrusion 29 causes the pin roller 27 to move. By being pivotally engaged beyond this, the transport posture A of the support arm 5 can be stably maintained. When the support arm 5 is rotated to one side and the end of the guide hole 28 opposite to the engaging projection 29 is locked to the pin roller 27, the support arm 5 is rotated. As a result, the sorting tray 6 is reversed around the overturning pin 26 to the discharge posture B. The sliders 7, 8 form an inclined edge 30 that is lowered at the outer end when the support arm 5 is in the transport posture A, and slide on the outer end of the guide rails 10, 11 and the tipping guide 12 surface. A contact edge 31 is formed. The sliding contact edge 31 is formed as a slanted inclined edge in a form that can be easily lifted up by the guide rails 10 and 11 and the fall guide 12. A stopper 32 for receiving the sorting tray 6 in a horizontal posture is provided on the upper portion of the support arm 5 so that the stopper 33 on the bottom of the sorting tray 6 can be received. Further, stoppers 34 and 35 for locking the fall position of the sorting pan 6 around the fall pin 26 are formed between the support arm 5 side that supports the fall pin 26 and the sorting tray 6 portion.

前記選別皿6は、選別物の対象物に応じて異なる形態に形成可能であるが、左右に長いバケット状形態に形成されて、一般の青果物はもとより、キューリ、ナスのような長物野菜類、芋類や、ハマチや、マダイのような鮮魚等を秤量、選別することができる。前記スライダ7、8を摺動させるガイドレール10、11は秤量行程域にロードセルの一部として構成される。選別フレーム19に設けられるロードセル9の秤量軸40の左右両端部の支持ブラケット41上に取付けられて、選別チエン1による搬送行程のうち秤量行程域にのみ短く設けられる。これら左右両側のガイドレール10、11によって受けられた重量をロードセル9で秤量検出する。この秤量は左右両側のガイドレール10、11で受けて選別物の秤量重量とすることができる。  The sorting dish 6 can be formed in different forms depending on the object of the sorting object, but is formed in a bucket shape that is long on the left and right sides, as well as general vegetables and fruits, long vegetables such as curry and eggplant, We can weigh and sort sardines, hamachi, fresh fish such as red sea bream. The guide rails 10 and 11 for sliding the sliders 7 and 8 are configured as a part of the load cell in the weighing process area. Attached on support brackets 41 at both left and right ends of the weighing shaft 40 of the load cell 9 provided in the sorting frame 19, are shortly provided only in the weighing stroke area in the conveying stroke by the sorting chain 1. The weight received by the left and right guide rails 10 and 11 is weighed and detected by the load cell 9. This weighing can be received by the guide rails 10 and 11 on both the left and right sides to obtain the weighing weight of the selected item.

前記転倒ガイド12は、支持アーム5をアーム軸4の周りに回動させる側とは反対側に設けられて、この側のスライダ7の移動経路の下側において、各選別排出位置に配置される。この転倒ガイド12は、選別フレーム19上のブラケット42に前後方向に沿うソレノイド軸43周りに回動するように構成される。このソレノイド軸43には、ロータリソレノイド44を有して一定角度往復回動される形態である。このソレノイド軸43の先端部に転倒ガイド12のアーム45を固定する。この転倒ガイド12は、外周の回動面がソレノイド軸43周りに円錐形状の傾斜面Cを形成するように構成すると共に、この回動方向の断面も円弧状、乃至曲面状Dに形成されて、この回動によってスライダ7を押し上げるとき、掬上げを正確に、円滑に行わせる形態としている。このような転倒ガイド12は、通常時は支持アーム5のスライダ7の移動経路の外側に位置するが、このスライダ7が選別排出位置に達すると外側から内側へソレノイド軸43回動されて、この転倒ガイド12の上周曲面D、及び傾斜曲面Cでスライダ7を掬い上げて、支持アーム5をアーム軸4周りに選別排出側へ回動させる。前記ウエイトサイザの各選別排出部には、選別皿6から排出される選別物を受けるシュータ47が設けられる。  The tipping guide 12 is provided on the side opposite to the side on which the support arm 5 is rotated around the arm shaft 4, and is disposed at each sorting and discharging position below the movement path of the slider 7 on this side. . The overturn guide 12 is configured to rotate around the solenoid shaft 43 along the front-rear direction with respect to the bracket 42 on the sorting frame 19. The solenoid shaft 43 has a rotary solenoid 44 and is reciprocated by a predetermined angle. The arm 45 of the fall guide 12 is fixed to the tip of the solenoid shaft 43. The tipping guide 12 is configured such that the outer peripheral rotation surface forms a conical inclined surface C around the solenoid shaft 43, and the rotation direction cross section is also formed in an arc shape or a curved surface shape D. When the slider 7 is pushed up by this rotation, the lifting is performed accurately and smoothly. Such a fall guide 12 is normally located outside the movement path of the slider 7 of the support arm 5, but when the slider 7 reaches the sorting and discharging position, the solenoid shaft 43 is rotated from the outside to the inside, and this The slider 7 is scooped up by the upper peripheral curved surface D and the inclined curved surface C of the fall guide 12, and the support arm 5 is rotated around the arm shaft 4 toward the sorting and discharging side. Each sorter discharge unit of the weight sizer is provided with a shooter 47 that receives a sorter discharged from the sorter 6.

供給コンベア17の駆動によって選別物がウエイトサイザの始端部の選別皿6に一個宛供給載置される。搬送チエン1の駆動によって各支持アーム5及びこの上部に支持された各選別皿6が搬送される。このとき支持アーム5及び選別皿6は、左右水平状態の搬送姿勢Aに維持される。この支持アーム5を支持する取付ブラケット2の左右両側部のスライダ22がレール21に嵌合支持されて、搬送チエン1の駆動によって移動案内される。選別物を受けた選別皿6が秤量位置を移動されると、支持アーム5の左右のスライダ7、8がガイドレール10、11上面を摺動されて秤量姿勢Eとなる。このガイドレール10、11で支持する重量がロードセル9によって検出されて、選別物の秤量重量となる。このロードセル9による秤量は、支持アーム5のアーム軸4周りの左右回動と、このアーム軸4自体に働く荷重を、左右ガイドレール10、11で受けてロードセル9で検出して、選別皿6の選別排出位置を指定する。左右ガイドレール10、11で受けた重量の合計に基づいて選別物の重量が演算されるため、選別皿6上の選別物の載置状態が左右に偏位していたり、選別物自体が長くて左右に重心位置が偏位していても、これら左右ガイドレール10、11を経る秤量によって正確な計量を行うことができる。  As the supply conveyor 17 is driven, one selected item is supplied and placed on the selection tray 6 at the start end of the weight sizer. Each support arm 5 and each sorting tray 6 supported on the upper part are transported by driving the transport chain 1. At this time, the support arm 5 and the sorting tray 6 are maintained in the transport posture A in the horizontal state. The sliders 22 on the left and right sides of the mounting bracket 2 that supports the support arm 5 are fitted and supported by the rails 21 and are moved and guided by driving of the transport chain 1. When the sorting tray 6 that has received the sorted product is moved to the weighing position, the left and right sliders 7 and 8 of the support arm 5 are slid on the upper surfaces of the guide rails 10 and 11 to be in the weighing posture E. The weight supported by the guide rails 10 and 11 is detected by the load cell 9 and becomes the weighed weight of the selected item. The weighing by the load cell 9 is performed by rotating the support arm 5 around the arm shaft 4 and the load acting on the arm shaft 4 itself by the left and right guide rails 10 and 11 and detecting it by the load cell 9. Specify the sorting discharge position. Since the weight of the sorting object is calculated based on the total weight received by the left and right guide rails 10 and 11, the placement state of the sorting object on the sorting dish 6 is deviated left and right, or the sorting object itself is long. Even if the position of the center of gravity is shifted to the left and right, accurate weighing can be performed by weighing through the left and right guide rails 10 and 11.

このようにして選別皿6の秤量作用が終るとスライダ7、8は、ガイドレール10、11から外れて搬送姿勢Aとなって、各秤量区分の選別排出域に搬送されると、ロードセル9の秤量に基づくコントローラ46からの出力によって、ソレノイド44が作動されて転倒ガイド12がソレノイド軸43の周りに回動されて、この選別排出位置を搬送され支持アーム5のスライダ7を掬い上げるように押し上げて、支持アーム5をアーム軸4の周りに回動させる。この支持アーム5の側方回動によっストッパ32、33等に受けられていた選別皿6が転倒ピン26の周りに反転回動されて、選別物を選別排出位置へ排出させる。この選別皿6は支持アーム5の回動によって外側方へ傾斜されて排出姿勢Bになると共に、外側へ反転回動されるため、支持アーム5の回動角が小さく制限されても、選別皿6は大きく傾斜、乃至反転されて選別排出を速やかに行わせる。支持アーム5及び選別皿6は排出作用が終ると排出姿勢Aに復帰されて、供給コンッベア17からの選別物供給を受ける始端行程に復帰移行される。  When the weighing operation of the sorting tray 6 is finished in this way, the sliders 7 and 8 are moved away from the guide rails 10 and 11 to the carrying posture A, and are conveyed to the sorting discharge area of each weighing section. The solenoid 44 is actuated by the output from the controller 46 based on the weighing so that the overturning guide 12 is rotated around the solenoid shaft 43 and is pushed up so that the slider 7 of the support arm 5 is scooped up by being transported through the sorting and discharging position. Then, the support arm 5 is rotated around the arm shaft 4. By the side rotation of the support arm 5, the sorting tray 6 received by the stoppers 32, 33 and the like is turned around the overturning pin 26 and discharged to the sorting discharge position. The sorting tray 6 is tilted outward by the rotation of the support arm 5 to be in the discharge posture B and is rotated in the reverse direction. Therefore, even if the rotation angle of the support arm 5 is limited to be small, the sorting tray 6 No. 6 is largely inclined or reversed so that sorting and discharging can be performed quickly. When the discharge operation is finished, the support arm 5 and the sorting tray 6 are returned to the discharge posture A, and are returned to the start stroke for receiving the supply of the selection from the supply conveyor 17.
