Description of the Related Art Conventionally, a pelletizer device that forms a pellet by cutting an object to be cut (synthetic resin or the like) extruded from a plurality of die holes provided in a die with a cutting blade is known. In this apparatus, the clearance between the die and the cutting blade greatly affects the quality of the pellet. Specifically, when the clearance is increased, the pellet quality is greatly reduced due to an increase in the shape of the pellet. It is known that this clearance adjustment is performed during operation of the pelletizer device.
　例えば、特許文献１には、ダイス面及び複数のノズルを有するダイスと、回転中心軸回りに回転する駆動軸と、駆動軸に接続されたホルダーと、ホルダーに保持された複数のカッターナイフと、ダイス面とカッターナイフとのクリアランスを調整する制御装置と、を備えたペレタイザ装置が開示されている。制御装置は、ペレタイザ装置の運転中（駆動軸の回転中）にカッターナイフとダイス面とのクリアランスを監視するとともにそのクリアランスを調整する。具体的に、制御装置は、回転中心軸と平行な方向についての駆動軸の位置を検知することにより前記クリアランスを監視し、カッターナイフの摩耗等に起因して前記クリアランスが所定値よりも大きくなった場合に、駆動軸を回転中心軸と平行な方向に沿ってダイス面側に変位させることによって前記クリアランスを所定範囲に調整する。 For example, in Patent Document 1, a die having a die surface and a plurality of nozzles, a drive shaft that rotates around a rotation center axis, a holder connected to the drive shaft, and a plurality of cutter knives held by the holder, A pelletizer device including a control device that adjusts the clearance between a die surface and a cutter knife is disclosed. The control device monitors the clearance between the cutter knife and the die surface and adjusts the clearance during operation of the pelletizer device (during rotation of the drive shaft). Specifically, the control device monitors the clearance by detecting the position of the drive shaft in a direction parallel to the rotation center axis, and the clearance becomes larger than a predetermined value due to wear of the cutter knife or the like. In this case, the clearance is adjusted to a predetermined range by displacing the drive shaft toward the die surface along a direction parallel to the rotation center axis.
　特許文献１に記載されるペレタイザ装置では、ペレットの品質の確保に限界がある。例えば、制御装置が前記クリアランスの調整を行ったとしても、カッターナイフのダイス面へのいわゆる片当たり（ダイス面の一部にのみ各カッターナイフが接触している状態）が生じている場合には、当該装置で製造されるペレットの中に低品質のもの（不良品）が生じる。この片当たりの解消には、例えば駆動軸のダイス面に対する傾きを調整する必要があるため、前記制御装置による前記クリアランスの監視及び駆動軸の回転中心軸と平行な方向への変位によって当該片当たりを解消することは困難である。さらに、片当たりの解消には、複数のダイス穴のうちいずれのダイス穴の通過後に形成されたペレットの形状に異常があるのかを検知する必要があるが、特許文献１に記載のペレタイザ装置では、この検知は困難である。具体的に、このペレタイザ装置で製造された各ペレットは、当該装置の下流側にて収集されるため、そこでペレットの異常（不良品）を発見することは可能であるものの、それがいずれのダイス穴の通過後に形成されたペレットであるのかを判断することはできない。 In the pelletizer device described in Patent Document 1, there is a limit in ensuring the quality of pellets. For example, even when the control device adjusts the clearance, when the so-called one-side contact with the die surface of the cutter knife (a state where each cutter knife is in contact with only a part of the die surface) occurs. A low quality product (defective product) is produced in the pellets produced by the apparatus. In order to eliminate this piece contact, for example, it is necessary to adjust the inclination of the drive shaft with respect to the die surface. Therefore, the clearance is monitored by the control device and the drive shaft is displaced in a direction parallel to the rotation center axis. It is difficult to eliminate. Furthermore, in order to eliminate the one-sided contact, it is necessary to detect whether there is an abnormality in the shape of the pellet formed after passing through which of the plurality of die holes. In the pelletizer device described in Patent Document 1, This detection is difficult. Specifically, since each pellet produced by this pelletizer device is collected downstream of the device, it is possible to find an abnormality (defective product) in the pellet, It cannot be determined whether the pellet is formed after passing through the hole.

　次に、各捕集具１０１～１０４が、複数の領域Ａ１～Ａ４のうちの一の領域に形成されたダイス穴１４の通過後に形成された各ペレットを、他の領域に形成されたダイス穴１４の通過後に形成されたものとほぼ混合される前にケース４０内において捕集可能な点について説明する。ここでは、第１捕集具１０１を例に説明する。 Next, each collecting tool 101 to 104 uses each pellet formed after passing through the die hole 14 formed in one of the plurality of regions A1 to A4 as a die hole formed in the other region. The points that can be collected in the case 40 before being substantially mixed with those formed after the passage of 14 will be described. Here, the first collector 101 will be described as an example.
　第１捕集具１０１は、捕集位置（図１において実線で示される位置及び図２で示される位置）と退避位置（図１において破線で示される位置）との間で移動可能となるように防水部材２００を介してケース４０に保持されている。 The first collecting tool 101 is movable between a collecting position (a position indicated by a solid line in FIG. 1 and a position indicated by FIG. 2) and a retracted position (a position indicated by a broken line in FIG. 1). In addition, the case 40 is held via the waterproof member 200.
　捕集位置は、ダイス面１２の第１領域Ａ１に形成されたダイス穴１４の通過後に形成されたペレットが、流入口４０ａから流出口４０ｂに向かう水とともに流出口４０ｂに向かう特定軌道上で、かつ、第１領域Ａ１とは異なる領域Ａ２～Ａ４に形成されたダイス穴１４の通過後に形成されたペレットが、流入口４０ａから流出口４０ｂに向かう水とともに流出口４０ｂに向かう他の軌道から離間した位置である。本実施形態では、捕集位置は、捕集口１１０ａが各切断刃３０を介して中心軸Ｏ１と平行な方向について第１領域Ａ１と重なる位置に設定されている。この捕集位置は、捕集口１１０ａが各切断刃３０から中心軸Ｏ１と平行な方向に僅かに離間した位置に設定されることが望ましい。捕集位置に位置した状態において、捕集具本体１１０は、底板１１３を含む当該捕集具本体１１０の一部がケース４０外に位置する形状に形成されている。このため、第１捕集具１０１が捕集位置に位置した状態において、第１蓋部材１３０の開閉操作をケース４０の外側で行うことができる。 The collection position is on a specific trajectory where the pellet formed after passing through the die hole 14 formed in the first region A1 of the die surface 12 goes to the outlet 40b together with water going from the inlet 40a to the outlet 40b. In addition, the pellets formed after passing through the die holes 14 formed in the regions A2 to A4 different from the first region A1 are separated from other trajectories toward the outlet port 40b together with water from the inlet port 40a toward the outlet port 40b. Is the position. In the present embodiment, the collection position is set to a position where the collection port 110a overlaps the first region A1 in the direction parallel to the central axis O1 via each cutting blade 30. The collection position is preferably set at a position where the collection port 110a is slightly separated from each cutting blade 30 in a direction parallel to the central axis O1. In the state located at the collection position, the collection tool main body 110 is formed in a shape in which a part of the collection tool main body 110 including the bottom plate 113 is located outside the case 40. For this reason, the first lid member 130 can be opened and closed outside the case 40 in a state where the first collection tool 101 is located at the collection position.
　退避位置は、第１捕集具１０１が前記特定軌道及び前記他の軌道の双方から退避する位置である。退避位置は、捕集口１１０ａが中心軸Ｏ１と平行な方向についてダイス面１２と重ならない位置に設定されることが望ましい。本実施形態では、退避位置は、捕集口１１０ａが周壁４４内に埋没する位置に設定されている。退避位置では、捕集具本体１１０の大部分及び第２蓋部材１４０は、ケース４０の外側に位置している。 The retreat position is a position where the first collecting tool 101 retreats from both the specific track and the other track. The retreat position is desirably set to a position where the collection port 110a does not overlap the die surface 12 in a direction parallel to the central axis O1. In the present embodiment, the retracted position is set to a position where the collection port 110 a is buried in the peripheral wall 44. In the retracted position, most of the collector main body 110 and the second lid member 140 are located outside the case 40.
　以上のように、第１捕集具１０１は捕集位置と退避位置との間を移動可能であるため、第１捕集具１０１を捕集位置に位置させた状態で第１蓋部材１３０を第１開放位置に位置させることによって、第１捕集具１０１により、実質的に第１領域Ａ１の通過後に形成されたペレットのみを捕集することが可能となる。このことは、第２捕集具１０２～第４捕集具１０４についても同様である。 As described above, since the first collecting tool 101 can move between the collecting position and the retracted position, the first lid member 130 is placed in a state where the first collecting tool 101 is located at the collecting position. By being located in the first open position, the first collecting tool 101 can substantially collect only the pellets formed after passing through the first region A1. The same applies to the second collecting tool 102 to the fourth collecting tool 104.
　次に、本ペレタイザ装置の動作について説明する。 Next, the operation of this pelletizer device will be described.
　まず、流入口４０ａから流出口４０ｂに向かってケース４０内に水が流される。これにより、収容空間Ｓ１が水で満たされる。この状態で回転軸２０がモータにより駆動される。なお、このとき、各捕集具１０１～１０４は、すべて退避位置に位置している。この状態において、各ダイス穴１４から被切断物（合成樹脂等）が押し出される。そうすると、その被切断物は、各切断刃３０により切断され、これにより複数のペレットが形成される。これらのペレットは、ケース４０内を上方に向かって流れる水とともに上方に流れ、流出口４０ｂからケース４０外に流出する。 First, water flows into the case 40 from the inlet 40a toward the outlet 40b. Thereby, the accommodation space S1 is filled with water. In this state, the rotating shaft 20 is driven by a motor. At this time, all the collecting tools 101 to 104 are located at the retracted position. In this state, an object to be cut (synthetic resin or the like) is pushed out from each die hole 14. Then, the object to be cut is cut by each cutting blade 30, thereby forming a plurality of pellets. These pellets flow upward together with the water flowing upward in the case 40 and flow out of the case 40 from the outlet 40b.
　その後、これらペレットは、当該ペレットを乾燥させる乾燥工程等を経た後に、所定の場所で収集される。 After that, these pellets are collected at a predetermined place after a drying process for drying the pellets.
　ここで、収集されたペレットに異常が確認された場合、各捕集具１０１～１０４を退避位置から捕集位置に移動させる挿入操作を行う。そして、各第１蓋部材１３０を第１閉塞位置から第１開放位置にスライドさせる開放操作を行う。そうすると、第１捕集具１０１には、第１領域Ａ１に形成されたダイス穴１４の通過後に形成された第１ペレットが捕集される。具体的に、第１捕集具１０１が捕集位置に位置した状態で第１蓋部材を第１開放位置に位置させると、捕集口１１０ａから排水口１１０ｂへ向かう水流が形成されるので、その水流とともに第１ペレットが捕集口１１０ａを通じて捕集具本体１１０内に流入する。その後、水は排水口１１０ｂから収容空間Ｓ１に排出される一方で第１ペレットは捕集空間Ｓ２に留まる。第２捕集具１０２～第４捕集具１０４においても同じ要領でペレットが捕集される。なお、前記開放操作は、すべての捕集具について同時に行われることが好ましい。 Here, when an abnormality is confirmed in the collected pellets, an insertion operation for moving each of the collecting tools 101 to 104 from the retracted position to the collecting position is performed. Then, an opening operation for sliding each first lid member 130 from the first closed position to the first opened position is performed. Then, the first pellet formed after passing through the die hole 14 formed in the first region A1 is collected in the first collecting tool 101. Specifically, when the first lid member is positioned at the first open position with the first collector 101 positioned at the collection position, a water flow from the collection port 110a toward the drain port 110b is formed. Along with the water flow, the first pellet flows into the collector main body 110 through the collector port 110a. Thereafter, water is discharged from the drain port 110b to the accommodation space S1, while the first pellet remains in the collection space S2. In the second collecting tool 102 to the fourth collecting tool 104, pellets are collected in the same manner. In addition, it is preferable that the said opening operation is performed simultaneously about all the collection tools.
　そして、例えば所定時間の経過後、各第１蓋部材１３０を第１開放位置から第１閉塞位置にスライドさせる閉塞操作を行う。これにより、捕集空間Ｓ２内へのペレットの流入が遮断される。その後、各捕集具１０１～１０４を捕集位置から退避位置に移動させる抜出操作を行い、第２蓋部材１４０を第２閉塞位置から第２開放位置にスライドさせる取出操作を行う。これにより、各捕集具１０１～１０４おいて、当該捕集具と対応する領域に形成されたダイス穴１４の通過後に形成されたペレットが、他の領域に形成されたダイス穴１４の通過後に形成された他のペレットと混ざる前に、すなわち、他のペレットから分離した状態で回収される。 For example, after a predetermined time has elapsed, a closing operation is performed in which each first lid member 130 is slid from the first opening position to the first closing position. Thereby, the inflow of pellets into the collection space S2 is blocked. Thereafter, an extraction operation for moving each of the collection tools 101 to 104 from the collection position to the retracted position is performed, and an extraction operation for sliding the second lid member 140 from the second closed position to the second open position is performed. Thereby, in each of the collectors 101 to 104, the pellets formed after passing through the die holes 14 formed in the region corresponding to the collectors are passed through the die holes 14 formed in other regions. Before being mixed with other formed pellets, that is, separated from the other pellets.
　よって、それぞれの捕集具で捕集されたペレットと正常なペレット（切断刃３０の形状や回転軸２０の姿勢が正常であるときに形成されるペレット）との相違を確認することにより、複数の領域Ａ１～Ａ４のうちいずれの領域に形成されたダイス穴１４の通過後に形成されたペレットが異常であるかを判別することができる。したがって、その判別結果に基づいて、各切断刃３０のダイス面１２へのいわゆる片当たりの発生を検知することができる。例えば、第１捕集具１０１及び第２捕集具１０２で捕集されたペレットの形状が第３捕集具１０３及び第４捕集具１０４で捕集されたペレットの形状よりも大きい場合、ダイス面１２のうち第３領域Ａ３及び第４領域Ａ４への各切断刃３０の片当たりが生じていると判断することができる。具体的に、第１捕集具１０１及び第２捕集具１０２で捕集されたペレットの形状が第３捕集具１０３及び第４捕集具１０４で捕集されたペレットの形状よりも大きい場合には、ダイス面１２のうち第１領域Ａ１及び第２領域Ａ２と各切断刃３０との第１クリアランスが、ダイス面１２のうち第３領域Ａ３及び第４領域Ａ４と各切断刃３０との第２クリアランスよりも大きくなっていると考えられる。すなわち、第１クリアランスが第２クリアランスよりも大きくなるように回転軸２０の回転中心軸Ｏ２が中心軸Ｏ１に対して傾斜しており、これにより第３領域Ａ３及び第４領域Ａ４への片当たりが生じていると判断することができる。この場合、第１クリアランスが小さくなるように回転軸２０の姿勢を調整することにより、片当たりの解消が可能である。 Therefore, by confirming the difference between the pellets collected by the respective collecting tools and normal pellets (pellets formed when the shape of the cutting blade 30 and the posture of the rotary shaft 20 are normal), It is possible to determine whether the pellet formed after passing through the die hole 14 formed in any one of the regions A1 to A4 is abnormal. Therefore, based on the determination result, it is possible to detect the so-called occurrence of each piece on the die surface 12 of each cutting blade 30. For example, when the shape of the pellets collected by the first collection tool 101 and the second collection tool 102 is larger than the shape of the pellets collected by the third collection tool 103 and the fourth collection tool 104, It can be determined that each of the cutting blades 30 hits the third area A3 and the fourth area A4 of the die surface 12. Specifically, the shape of the pellets collected by the first collection tool 101 and the second collection tool 102 is larger than the shape of the pellets collected by the third collection tool 103 and the fourth collection tool 104. In this case, the first clearance between the first region A1 and the second region A2 of the die surface 12 and each cutting blade 30 is the same as the third region A3 and the fourth region A4 of the die surface 12 and each cutting blade 30. This is considered to be larger than the second clearance. That is, the rotation center axis O2 of the rotation shaft 20 is inclined with respect to the center axis O1 so that the first clearance is larger than the second clearance, and thus the one-side contact with the third region A3 and the fourth region A4. Can be determined. In this case, by adjusting the posture of the rotating shaft 20 so that the first clearance is reduced, the one-sided contact can be eliminated.
　また、例えば第１捕集具１０１におけるペレットの捕集量が他の捕集具１０２～１０４のそれに比べて著しく少ない場合、第１領域Ａ１に形成されたダイス穴１４に詰まりが生じていると推察される。 For example, when the amount of pellets collected in the first collector 101 is significantly smaller than that of the other collectors 102 to 104, the die hole 14 formed in the first region A1 is clogged. Inferred.
　以上説明したように、本ペレタイザ装置では、各捕集具１０１～１０４を退避位置にすることにより各ペレットが水とともにスムーズに流出口４０ｂから流出する一方、各捕集具１０１～１０４を捕集位置にすることにより、各捕集具１０１～１０４は、ダイス面１２の特定の領域に形成されたダイス穴１４の通過後に形成された特定ペレットとダイス面１２の他の領域に形成されたダイス穴１４の通過後に形成された他のペレットとが略混ざる前に前記特定ペレットを捕集することができる。よって、各捕集具１０１～１０４でそれぞれペレットを捕集することにより、いずれの領域に形成されたダイス穴１４の通過後に形成されたペレットに異常があるのかを判別することが可能となる。 As described above, in this pelletizer device, each of the collecting tools 101 to 104 is smoothly discharged from the outlet 40b together with water by setting each of the collecting tools 101 to 104 to the retracted position. By setting the position, each of the collectors 101 to 104 has a specific pellet formed after passing through the die hole 14 formed in a specific region of the die surface 12 and a die formed in another region of the die surface 12. The specific pellets can be collected before the other pellets formed after passing through the holes 14 are substantially mixed. Therefore, by collecting the pellets with the respective collecting tools 101 to 104, it is possible to determine in which region the pellet formed after passing through the die hole 14 is abnormal.
　また、捕集具本体１１０が退避位置に位置する状態では、ペレット取出口１１０ｃがケース４０外に位置するので、捕集具本体１１０に捕集されたペレットの取出操作、すなわち、第２蓋部材１４０を第２閉塞位置から第２開放位置にする操作をケース４０外で行うことができる。 Further, in the state where the collector main body 110 is located at the retracted position, the pellet outlet 110c is located outside the case 40. Therefore, an operation for taking out the pellets collected in the collector main body 110, that is, the second lid member. The operation of moving 140 from the second closed position to the second open position can be performed outside the case 40.
　なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 In addition, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.
　例えば、各捕集具１０１～１０４は、ケース４０の周壁４４に保持される例に限られない。各捕集具１０１～１０４は、前壁４２に保持されてもよい。 For example, the collectors 101 to 104 are not limited to the example held on the peripheral wall 44 of the case 40. Each collector 101 to 104 may be held on the front wall 42.
　また、各捕集具１０１～１０４によるペレットの捕集は、自動的に行われてもよい。つまり、前記挿入操作、前記開放操作、前記閉塞操作、前記抜出操作及び前記取出操作が、一定期間ごとに自動的に行われてもよい。 In addition, the collection of pellets by the collection tools 101 to 104 may be performed automatically. That is, the insertion operation, the opening operation, the closing operation, the extraction operation, and the extraction operation may be automatically performed at regular intervals.
　ここで、上記実施形態について概説する。 Here, the above embodiment will be outlined.
　本実施形態のペレタイザ装置は、水中で被切断物を切断することによりペレットを形成するペレタイザ装置であって、特定の中心軸に対して直交するダイス面と、前記特定の中心軸を中心とする周方向に沿って並ぶとともに前記ダイス面から前記被切断物を押し出すための複数のダイス穴と、を有するダイスと、前記特定の中心軸と平行な回転中心軸回りに回転する回転軸と、各ダイス穴から押し出された被切断物を切断可能となるように前記回転軸に固定された切断刃と、前記回転軸、前記切断刃、及び、各ダイス穴から押し出された被切断物が前記切断刃で切断されることにより形成されるペレットを収容する収容空間を有し、かつ、前記収容空間に水を流入させるための流入口と前記水とともに前記ペレットを前記収容空間から流出させるための流出口とを有するケースと、それぞれが前記ケースに保持されかつ前記ペレットを捕集する複数の捕集具と、を備え、前記複数の捕集具は、それぞれが、前記ダイス面において前記周方向に沿って並ぶ複数の領域のうち互いに異なる領域に形成されたダイス穴から押し出された後に前記切断刃で切断されることにより形成されたペレットを捕集可能となるように前記ケースに保持されており、各捕集具は、前記複数の領域のうちの特定の領域に形成されたダイス穴の通過後に形成された特定ペレットが前記流入口から前記流出口に向かう水とともに前記流出口に向かう特定軌道上でかつ前記複数の領域のうち前記特定の領域とは異なる領域に形成されたダイス穴の通過後に形成された他のペレットが、前記流入口から前記流出口に向かう水とともに前記流出口に向かう他の軌道から離間した捕集位置と、前記特定軌道及び前記他の軌道の双方から退避した退避位置と、の間で移動可能となるように前記ケースに保持されている。 The pelletizer device according to the present embodiment is a pelletizer device that forms pellets by cutting an object to be cut in water. The pelletizer device has a die surface orthogonal to a specific central axis and the specific central axis as a center. A plurality of die holes arranged along the circumferential direction and for extruding the object to be cut from the die surface; a rotation shaft that rotates about a rotation center axis parallel to the specific center axis; and The cutting blade fixed to the rotary shaft so as to be able to cut the workpiece pushed out from the die hole, the rotary shaft, the cutting blade, and the workpiece pushed out from each die hole are cut. A storage space for storing pellets formed by cutting with a blade; and an outlet for allowing water to flow into the storage space; and the pellets flow out of the storage space together with the water. And a plurality of collecting tools each of which is held by the case and collects the pellets, and each of the plurality of collecting tools is arranged on the die surface. In the case, the pellets formed by being cut by the cutting blade after being pushed out from the die holes formed in different regions among the plurality of regions arranged along the circumferential direction can be collected. Each collecting tool is held in the outlet with the specific pellets formed after passing through the die holes formed in the specific area of the plurality of areas together with water from the inlet toward the outlet. The other pellets formed after passing through the die holes formed on the specific trajectory heading to the region different from the specific region out of the plurality of regions are transferred from the inflow port to the outflow port. It is held in the case so as to be movable between a collection position separated from the other trajectory toward the outflow port with the water going to the retreat position retracted from both the specific trajectory and the other trajectory. ing.
　本ペレタイザ装置では、各捕集具を退避位置にすることにより各ペレットが水とともにスムーズに流出口から流出する一方、各捕集具を捕集位置にすることにより、各捕集具は、ダイス面の特定の領域に形成されたダイス穴の通過後に形成された特定ペレットとダイス面の他の領域に形成されたダイス穴の通過後に形成された他のペレットとが略混ざる前に前記特定ペレットを捕集することができる。具体的に、捕集位置は、前記特定ペレットが水とともに流出口に向かう特定軌道上でかつ前記他のペレットが水とともに流出口に向かう他の軌道から離間した位置であるので、捕集具を捕集位置にすることにより、当該捕集具では、実質的に前記特定軌道に沿って流れる特定ペレットのみが捕集される。よって、流出口から流出したペレットに異常が確認された場合に、複数の捕集具をそれぞれ捕集位置に移動させることにより各捕集具でペレットを捕集し、それぞれの捕集具で捕集されたペレットと正常なペレット（切断刃の形状や回転軸の姿勢が正常であるときに形成されるペレット）との相違を確認することにより、いずれの領域に形成されたダイス穴の通過後に形成されたペレットが異常であるかを判別することができる。したがって、その判別結果に基づいて、切断刃のダイス面へのいわゆる片当たりの発生を検知することができる。具体的に、特定の捕集具で捕集されたペレットが他の捕集具で捕集されたペレットよりも大きな形状を有する場合、特定の捕集具の捕集位置に対応する位置での切断刃とダイス面とのクリアランスが相対的に大きくなるように、回転軸が前記特定の中心軸から傾斜していると判断することができる。また、特定の捕集具におけるペレットの捕集量が他の捕集具のそれに比べて著しく少ない場合、当該特定の捕集具に対応する位置に形成されたダイス穴に詰まりが生じていると考えられる。 In this pelletizer device, each pellet is smoothly discharged from the outlet together with water by setting each collector to the retracted position, while each collector is placed in the die position by setting each collector to the collection position. The specific pellet formed after passing through the die hole formed in the specific area of the surface and the specific pellet formed before the other pellet formed after passing through the die hole formed in the other area of the die surface are substantially mixed. Can be collected. Specifically, the collection position is a position on a specific trajectory where the specific pellet goes to the outlet together with water and a position apart from the other trajectory where the other pellet goes to the outlet together with water. By setting the collection position, only the specific pellet that flows substantially along the specific trajectory is collected in the collection tool. Therefore, when an abnormality is confirmed in the pellet flowing out from the outlet, the pellets are collected by each collecting tool by moving each of the collecting tools to the collecting position, and captured by each collecting tool. After passing through the die hole formed in any region by checking the difference between the collected pellets and normal pellets (pellets formed when the shape of the cutting blade and the orientation of the rotating shaft are normal) It is possible to determine whether the formed pellet is abnormal. Therefore, based on the determination result, it is possible to detect the so-called per-cut occurrence on the die surface of the cutting blade. Specifically, when the pellet collected by a specific collector has a larger shape than the pellet collected by another collector, the position at the position corresponding to the collection position of the specific collector It can be determined that the rotation axis is inclined from the specific central axis so that the clearance between the cutting blade and the die surface is relatively large. Also, if the amount of pellets collected in a specific collector is significantly smaller than that of other collectors, the die hole formed at the position corresponding to the specific collector is clogged. Conceivable.
　具体的に、各捕集具は、前記ペレットを捕集する捕集空間を有し、かつ、前記捕集空間に水と前記ペレットとを流入させるための捕集口、前記捕集空間から水を排出するための排水口及び前記ペレットを取り出すためのペレット取出口を有する捕集具本体と、水の前記排水口の通過を許容するとともに前記ペレットの前記排水口の通過を阻止する阻止部材と、前記捕集口を閉塞可能な形状を有し、かつ、前記捕集口を閉塞する第１閉塞位置と前記捕集口を開放する第１開放位置との間で前記捕集具本体に対して変位可能な第１蓋部材と、前記ペレット取出口を閉塞可能な形状を有し、かつ、前記ペレット取出口を閉塞する第２閉塞位置と前記ペレット取出口を開放する第２開放位置との間で前記捕集具本体に対して変位可能な第２蓋部材と、を有し、前記捕集具本体は、前記捕集位置において前記捕集口が前記ダイス面における前記特定の領域と対向し、かつ、前記退避位置として前記捕集口が前記特定軌道及び前記他の軌道の双方から離間する位置に位置したときに前記ペレット取出口が前記ケースの外側に位置する姿勢で前記ケースに保持されていることが好ましい。 Specifically, each collection tool has a collection space for collecting the pellets, a collection port for allowing water and the pellets to flow into the collection space, and water from the collection space. A collector main body having a drain outlet for discharging the pellet and a pellet outlet for taking out the pellet, and a blocking member that allows passage of the drain outlet of water and prevents passage of the pellet through the drain outlet; The collector main body has a shape capable of closing the collection port, and between the first closed position for closing the collection port and the first open position for opening the collection port. A first lid member displaceable, a shape capable of closing the pellet outlet, and a second closing position for closing the pellet outlet and a second opening position for opening the pellet outlet. A second lid member displaceable relative to the collector main body between The collector main body is opposed to the specific region in the die surface at the collection position, and the collection port is the specific track and the other as the retracted position. It is preferable that the pellet take-out port is held by the case in a posture that is located outside the case when it is located at a position away from both of the tracks.
　このようにすれば、第２蓋部材を第２閉塞位置にするとともに捕集具本体を捕集位置に位置させた状態で第１蓋部材を第１閉塞位置から第１開放位置にすることにより、捕集口から排水口に向かう水流が形成されるので、捕集口と対向する領域に形成されているダイス穴の通過後に形成された特定ペレットが捕集具本体に有効に捕集される。さらに、捕集具本体が退避位置に位置する状態ではペレット取出口がケース外に位置するので、捕集具本体に捕集されたペレットの取出操作、すなわち、第１蓋部材が第１閉塞位置に位置するとともに捕集具本体が退避位置に位置する状態で第２蓋部材を第２閉塞位置から第２開放位置にする操作をケース外で行うことができる。 By doing so, the first lid member is moved from the first closed position to the first opened position while the second lid member is set to the second closed position and the collector main body is positioned to the collection position. Since the water flow from the collection port to the drain port is formed, the specific pellet formed after passing through the die hole formed in the region facing the collection port is effectively collected in the collector body. . Furthermore, since the pellet outlet is located outside the case in the state where the collector main body is located at the retracted position, the operation of taking out the pellets collected in the collector main body, that is, the first lid member is in the first closed position. The second lid member can be operated outside the case from the second closed position to the second open position with the collector main body positioned at the retracted position.
　また、本実施形態のペレットの捕集方法は、特定の中心軸に対して直交するダイス面と、前記特定の中心軸を中心とする周方向に沿って並ぶとともに前記ダイス面から被切断物を押し出すための複数のダイス穴と、を有するダイスと、前記特定の中心軸と平行な回転中心軸回りに回転する回転軸と、各ダイス穴から押し出された被切断物を切断可能となるように前記回転軸に固定された切断刃と、前記回転軸、前記切断刃、及び、各ダイス穴から押し出された被切断物が前記切断刃で切断されることにより形成されるペレットを収容する収容空間を有し、かつ、前記収容空間に水を流入させるための流入口と前記水とともに前記ペレットを前記収容空間から流出させるための流出口とを有するケースと、を備えるペレタイザ装置で形成されたペレットを捕集するペレットの捕集方法であって、前記流入口から流入した後に前記収容空間を経て前記流出口から流出するように水を流した状態で各ダイス穴を通じて押し出された被切断物を各切断刃で切断することによりペレットを形成するペレット形成工程と、前記ペレット形成工程で形成されたペレットを捕集する捕集工程と、を備え、前記捕集工程では、前記ダイス面において前記周方向に沿って並ぶ複数の領域のうち互いに異なる領域に形成されたダイス穴から押し出された後に各切断刃で切断されることにより形成された各ペレットを、互いに分離した状態で捕集する。 In addition, the pellet collecting method of the present embodiment includes a die surface orthogonal to a specific central axis, and a line to be cut along the circumferential direction centered on the specific central axis. A die having a plurality of die holes for extruding, a rotating shaft rotating around a rotation center axis parallel to the specific center axis, and a workpiece extruded from each die hole can be cut. A storage space for storing a cutting blade fixed to the rotary shaft, and pellets formed by cutting the rotary shaft, the cutting blade, and a workpiece pushed out from each die hole with the cutting blade.
