なお、上記開腹ナイフ３、腹須除去ナイフ４、フィレーナイフ５、５、背部開きナイフ６は、機台１上に設置した駆動モータ15により、適宜な伝達手段を介して魚体Ａを切断する刃先部が搬送ベルト２、２の搬送方向に所定の回転速度でもって回転するように構成されている。 The above-mentioned laparotomy knife 3, bellows removal knife 4, fillet knives 5, 5, and back opening knife 6 are blade tips for cutting the fish body A through an appropriate transmission means by a drive motor 15 installed on the machine base 1. The section is configured to rotate at a predetermined rotational speed in the transport direction of the transport belts 2 and 2.

このように構成した魚体処理装置によって魚体Ａを吊り干し開きフィレーA2に切断加工処理するには、まず、秋刀魚や鰺等の魚体Ａの頭部を切断処理しておき、この魚体Ａをその切断頭部側を前方、即ち、下流側に向け、且つ、腹部を下方に向けた状態でロアーシュート７上に順次、供給し、左右一対の搬送ベルト２、２の搬送始端部間で挟持させてロアーシュート７に案内させながら下流側に向かって搬送する。搬送ベルト２、２によって挟持された魚体Ａが開腹ナイフ３に達すると、この開腹ナイフ３によって腹部が図３に示すように中骨a1の下面に達するまで切り込まれて左右に二分割されると共にその開腹によって内臓が落下、除去される。なお、この内臓の除去は周知のガッティングナイフを開腹ナイフ３の前方側に配設しておいて、このガッティングナイフにより積極的に行うように構成しておいてもよい。 In order to cut and process fish A by hanging and opening the fillet A2 by the fish processing apparatus configured as described above, first, the head of the fish A such as sword fish or carp is cut and cut. Sequentially feed the lower chute 7 with the head side forward, ie, downstream, and the abdomen downward, and sandwiched between the conveyance start ends of the pair of left and right conveyance belts 2 and 2 It is conveyed toward the downstream side while being guided by the lower chute 7 . When fish A sandwiched by the conveyor belt 2, 2 reaches laparotomy knife 3, abdominal this laparotomy knife 3 is divided into two right and left cut until reaching the lower surface of Chukotsu a 1 as shown in FIG. 3 At the same time, the internal organs are dropped and removed by the laparotomy. Note that the removal of the internal organs may be configured so as to be performed positively by a known gating knife provided on the front side of the laparotomy knife 3.

開腹された魚体Ａは、図４に示すように、第１ロアーガイド８上に跨がった状態で搬送ベルト２、２により挟持されながら水平面内で回転する左右一対の腹須除去ナイフ４、４に送り込まれ、この腹須除去ナイフ４、４により腹部の両側腹須a3、a3が切除される。なお、この腹須除去ナンフ４、４は水平状に配設することなく、互いに近接した外周先端側から外側方に向かって斜め下方に傾斜した状態で配設しておいてよい。また、この腹須除去ナイフ４、４は必ずしも設けておく必要はない。 As shown in FIG. 4, the opened fish A is a pair of left and right belly culm removal knives 4 that rotate in a horizontal plane while being sandwiched between the conveyor belts 2 and 2 while straddling the first lower guide 8. 4, the abdominal sides of the abdomen a 3 , a 3 are excised by the abdominal sac removal knives 4, 4. The bellows removal nanphs 4 and 4 may be disposed in a state of being inclined obliquely downward from the outer peripheral tip side close to each other toward the outer side without being disposed horizontally. Moreover, it is not always necessary to provide the belly blade removal knives 4 and 4.

次いで、魚体Ａは第２ロアーガイド９側に送り出されて図５に示すようにこの第２ロアーガイド９上に跨がった状態で左右一対のフィレーナイフ５、５に送り込まれる。開腹された魚体Ａは第２ロアーガイド９上においては、その中骨a1をこの第２ロアーガイド９の稜角部上に乗せ、且つ、両側の腹須骨a2、a2を該第２ロアーガイド９の両側傾斜面上に摺接させた状態で搬送ベルト２、２により挟持されながら回転円形カッタからなる左右一対のフィレーナイフ５、５に送り込まれるものであり、さらに、この左右一対のフィレーナイフ５、５は第２ロアーガイド９の両側傾斜面に小間隔を存してその上周部における対向面をそれぞれ沿わせているので、搬送ベルト２、２によって挟持されながらこれらのフィレーナイフ５、５に送り込まれる魚体Ａの腹須骨a2、a2と開腹された両側肉部との間にその刃部を切り込ませていくと共に、これらのフィレーナイフ５、５の互いに接触又は近接した上端対向部間に中骨a1を位置させた状態でこれらの上端刃先部により中骨a1を背部の下端肉部から切除していき、背部と一体に連なった左右のフィレーA11 、A11 に切断加工処理する。 Next, the fish body A is sent to the second lower guide 9 side, and is sent to the pair of left and right fillet knives 5 and 5 while straddling the second lower guide 9 as shown in FIG. On the second lower guide 9, the opened fish body A has its central bone a 1 placed on the ridge corner of the second lower guide 9, and the stomach stabs a 2 and a 2 on both sides are placed on the second lower guide 9. It is fed into a pair of left and right fillet knives 5 and 5 consisting of rotating circular cutters while being held between the conveying belts 2 and 2 while being in sliding contact with both inclined surfaces of the lower guide 9. The fillet knives 5 and 5 are arranged on the inclined surfaces on both sides of the second lower guide 9 so that the opposing surfaces in the upper peripheral portion thereof are along a small interval, so that these fillet knives are held by the conveyor belts 2 and 2. 5 and 5, the blades are cut between the gastric scaps a 2 and a 2 of the fish body A fed to the fish body A and the opened both side meat parts, and the fillet knives 5 and 5 contact each other or Between adjacent top facing parts In a state of being positioned bone a 1 continue to cut medium bone a 1 from the lower end wall portion of the back by these upper cutting edge, for cutting processed into fillet A11, A11 of the left and right that continuous to the back and integrally.

この際、魚体Ａはその背部を押さえ部材11によってフィレーナイフ５、５側に押し付けられ、且つ、搬送ベルト２、２によって中骨a1を水平状に保持しながらフィレーナイフ５、５により該中骨a1と両側腹須骨a2、a2とを切除していくが、尾部側は胴部よりも厚みが薄いので、胴部が搬送ベルト２、２による挟持されていても尾部は挟持されてなく、その上、背部が押さえ部材11により下方に押圧されると共にフィレーナイフ５、５は搬送方向に回転しているので、尾部がフィレーナイフ５、５の切断刃に送り込まれた時には、挟持されている胴部を支点としてその尾部が上方に回動するように持ち上がり、中骨a1が切断頭部側から尾部側に向かうに従って上方に傾斜して尾部側の中骨端部a1' がフィレーナイフ５、５の上端刃先に対して下方側から上方に交差した状態となり、この状態でフィレーナイフ５、５によって尾部近傍部の中骨a1の端部が切断されながら尾部がフィレーナイフ５、５上を通過し、左右のフィレーA11 、A11 が背部を介して一体に連なり且つ尾部を有する尾付きフィレーA1に切断加工処理される。 At this time, the fish A is pressed against the fillet knives 5 and 5 by the pressing member 11 while the fish A is held in the middle by the fillet knives 5 and 5 while holding the central bone a 1 horizontally by the conveyor belts 2 and 2. Bone a 1 and bilateral scapula a 2 and a 2 are excised, but the tail is thinner than the torso, so the tail is nipped even if the torso is nipped by the conveyor belts 2 and 2 In addition, since the back portion is pressed downward by the pressing member 11 and the fillet knives 5 and 5 are rotated in the conveying direction, when the tail portion is fed into the cutting blades of the fillet knives 5 and 5, The tail part is lifted so that the tail part pivots upward with the clamped body part as a fulcrum, and the middle bone a 1 is inclined upward as it goes from the cut head side to the tail part side, and the middle bone edge part a 1 on the tail part side 'Is below the upper edge of the fillet knife 5 or 5 A state intersecting the side upward, the tail while the ends of the bone a 1 is cut in a tail near portion passes over fillet over knife 5,5 by fillet over knives 5,5 In this state, the left and right fillets A11, A11 is cut and processed into a tail-filled fillet A1 having a tail portion and continuous with the back portion.

この尾付きフィレーA1は、その左右のフィレーA11 、A11 を広げた状態で搬送ベルト２、２に挟持されながらフィレーナイフ５、５側から第３ロアーガイド10上に送り出され、図６に示すように、この第３ロアーガイド10上に跨がった状態で搬送ベルト２、２により挟持されながら前方に搬送されて背部開きナイフ６に達し、この背部開きナイフ６によって尾付きフィレーA1がその尾部を残して左右のフィレーA11 、A11 に分断されると共に、尾部に残存している中骨端部a1' は切断されることなく背部開きナイフ６の回転に従ってその刃先に掛止した状態で背部開きナイフ６上を通過し、分割した左右のフィレーA11 、A11 が尾部によって繋がった吊り干し開きフィレーA2に加工処理される。 The tail-filled fillet A1 is fed from the fillet knife 5 and 5 side onto the third lower guide 10 while being sandwiched between the conveying belts 2 and 2 with the left and right fillets A11 and A11 being unfolded, as shown in FIG. In the state of being straddled on the third lower guide 10, it is transported forward while being sandwiched by the transport belts 2, 2 to reach the back opening knife 6, and the back opening knife 6 causes the tailed fillet A 1 to have its tail The left and right fillets are divided into left and right fillets A11 and A11, and the middle bone end a 1 ′ remaining in the tail is not cut and is backed by being hooked to the blade edge according to the rotation of the back opening knife 6 After passing over the open knife 6, the divided left and right fillets A11, A11 are processed into a hanging dry fillet A2 connected by a tail.

詳しくは、背部開きナイフ６は、その外周上部を上記左右一対の搬送ベルト２、２の対向面間の中央部に位置させ、且つ、その上端刃先をアッパーガイド12の前端部に設けている隙間13内に介入させている一方、この背部開きナイフ６の外周上部における搬送始端部側、即ち、上流側に向けている後側刃先に上記第３ロアーガイド10の前端面を近接させているので、この第３ロアーガイド10上に跨がって搬送されてくる尾付きフィレーA1が背部開きナイフ６に達すると、この背部開きナイフ６によって背部の上端から腹腔間に亘り胴部の中央が縦に切断されながら、搬送ベルト２、２により搬送されて背部開きナイフ６を通過し、背部を介して一体に連なっていた左右のフィレーA11 、A11 が二分割される。   Specifically, the back opening knife 6 has an outer peripheral upper portion positioned at a central portion between the opposing surfaces of the pair of left and right conveying belts 2 and 2 and a top edge provided at the front end portion of the upper guide 12. 13, while the front end surface of the third lower guide 10 is in close proximity to the conveyance start end side of the upper part of the outer periphery of the back opening knife 6, that is, the rear cutting edge facing the upstream side. When the tailed fillet A1 conveyed over the third lower guide 10 reaches the back opening knife 6, the back opening knife 6 causes the center of the torso to extend vertically from the upper end of the back to the abdominal cavity. The left and right fillets A11 and A11 which are conveyed by the conveyor belts 2 and 2 and pass through the back opening knife 6 and are continuously connected to each other through the back are divided into two.

この際、尾付きフィレーA1が背部開きナイフ６の外周上部における上流側の刃先によって切り込まれていくと、背部開きナイフ６が搬送方向に回転しているので、その切り込まれた部分は背部開きナイフ６の回転に従って押し上げられる方向に圧力を受けながら切断されていくが、尾付きフィレーA1の左右のフィレーA11 、A11 の外側面、即ち、胴部の両側面は搬送ベルト２、２によって挟持されており、且つ、アッパーガイド12によって背部の上端が受止されるので、上方に移動させられることなく背部開きナイフ６によって確実に背部が尾部近傍部に至るまで左右に切断されて左右のフィレーA11 、A11 に分割することができる。   At this time, when the tail-filled fillet A1 is cut by the upstream cutting edge in the upper part of the outer periphery of the back opening knife 6, the back opening knife 6 is rotated in the conveying direction, so that the cut portion is the back part. Although it is cut while receiving pressure in the direction in which it is pushed up according to the rotation of the opening knife 6, the left and right fillets A11, A11 of the tailed fillet A1, that is, the outer side surfaces of the trunk, are sandwiched between the conveyor belts 2, 2. Since the upper end of the back portion is received by the upper guide 12, the back portion is reliably cut by the back opening knife 6 without being moved upward until it reaches the vicinity of the tail portion. It can be divided into A11 and A11.

この尾付きフィレーA1の胴部が背部開きナイフ６を通過して左右のフィレーA11 、A11に二分割され、引き続いて尾部が背部開きナイフ６の外周上部における上流側に面している刃先に達すると、尾部が胴部よりも厚みが薄くて上記搬送ベルト２、２によって強固に挟持されてなく且つその尾部には中骨端部a1' が残存しているので、この中骨端部a1' が背部開きナイフ６の外周上部における上流側に面している刃先に当接した時に切断されることなくこの背部開きナイフ６の刃先に該中骨端部a1' を掛止させた状態にして図８〜図10に示すように、背部開きナイフ６の回転力によって上方に持ち上げられながら該中骨端部a1' を有する尾部が背部開きナイフ６上に乗り上げた状態でこの背部開きナイフ６の回転に従って搬送方向に送り出される。この際、尾部が背部開きナイフ６の上端とアッパーガイド12の前端部間に達すると、このアッパーガイド12の隙間13内に入り込みながら背部開きナイフ６上を通過して排出シュート14上に送り出される。 The body of this tailed fillet A1 passes through the back opening knife 6 and is divided into two left and right fillets A11 and A11. Subsequently, the tail reaches the cutting edge facing the upstream side of the upper periphery of the back opening knife 6. Then, since the tail portion is thinner than the trunk portion and is not firmly sandwiched between the conveying belts 2 and 2 and the middle bone end a 1 ′ remains in the tail, the middle bone end a 1 was hooked to 'this back open middle bone ends a 1 the cutting edge of the knife 6 without being cut when in contact with the cutting edge facing the upstream side in the outer peripheral upper portion of the back opening knives 6' As shown in FIGS. 8 to 10, the back portion is lifted upward by the rotational force of the back opening knife 6 and the tail portion having the middle bone end a 1 ′ is riding on the back opening knife 6. It is sent out in the conveying direction according to the rotation of the opening knife 6 At this time, when the tail reaches between the upper end of the back opening knife 6 and the front end of the upper guide 12, it passes over the back opening knife 6 and is sent out onto the discharge chute 14 while entering the gap 13 of the upper guide 12. .

背部開きナイフ６による尾付きフィレーA1の胴部から尾部に至る切断処理は瞬時に行われ、搬送ベルト２、２によって搬送されてくる魚体Ａを次々と連続的に吊り干し開きフィレーA2に切断加工処理していくものである。この吊り干し開きフィレーA2の加工処理は、上述したように、開腹ナイフ３によって開腹された魚体Ａを左右一対のフィレーナイフ５、５によって尾付きフィレーA1とし、この尾付きフィレーA1を背部開きナイフ６によってその尾部に残存している中骨端部a1' に達するまで左右のフィレーA11 、A11 に切断して吊り干し開きフィレーA2を得るものであるから、全ての魚体Ａを正確に且つ能率よく吊り図11に示すような干し開きフィレーA2に切断加工処理することができる。 The cutting process from the trunk part to the tail part of the tail-filled fillet A1 by the back opening knife 6 is performed instantaneously, and the fish bodies A transported by the transport belts 2 and 2 are continuously and continuously cut into the open-filled fillet A2. It will be processed. As described above, the processing of the hanging open fillet A2 is carried out by using the fish body A opened by the laparotomy knife 3 as a pair of left and right fillet knives 5 and 5 to form a tailed fillet A1, and this tailed fillet A1 is used as a back opening knife. 6 to cut the left and right fillets A11, A11 until the end of the middle bone a 1 ′ remaining in the tail is reached to obtain the open-filled fillet A2, so that all fish A can be accurately and efficiently operated. It can be cut and processed into a well-opened fillet A2 as shown in FIG.
