Description

本発明は、インパクトクラッシャ等の破砕装置に対し、コンクリートがら等の破砕対象物を移送して装置内に投入する移送システムに関する。   The present invention relates to a transfer system that transfers an object to be crushed, such as concrete waste, to a crushing apparatus, such as an impact crusher, and puts it into the apparatus.

インパクトクラッシャ等の破砕装置では、装置のケーシング内部で破砕用の打撃子を動かし、投入された破砕対象物を打撃子と衝突させて破砕したり、ケーシング内部に固定設置された反撥板に対し、打撃子に当たって撥ね飛ばされた破砕対象物をさらに衝突させて破砕する仕組みを有している。   In a crushing device such as an impact crusher, a crusher for crushing is moved inside the casing of the device, the crushing target object is collided with the crusher and crushed, or against a repellent plate fixedly installed inside the casing, It has a mechanism for further colliding and crushing the object to be crushed by hitting the striker.

そして、こうした破砕装置では、破砕対象物をベルトコンベヤ等で移送し、コンベヤ端部から送り出されて落下する破砕対象物が破砕装置の投入口に投入されるようにして、破砕対象物を継続的に供給される仕組みとされるのが一般的である。   In such a crushing device, the crushing object is transferred by a belt conveyor or the like, and the crushing object sent out from the end of the conveyor and dropped is introduced into the inlet of the crushing device, so that the crushing object is continuously supplied. It is common for the system to be supplied to

破砕装置は、投入口から投入された破砕対象物を打撃子や反撥板との一又は複数回の衝突により破砕した後、破砕された破砕片を下部に落下させ、ケーシングの排出口から破砕片を外部に排出させる。   The crushing device crushes an object to be crushed from the inlet by one or more collisions with a striker or a repulsion plate, and then drops the crushed piece to the lower part, and then crushes the fragment from the outlet of the casing. To the outside.

この従来の破砕装置における打撃子や反撥板は、直接破砕対象物と衝突することから、破砕装置の使用に伴って摩耗していく。そして、打撃子や反撥板が摩耗すると、破砕対象物の破砕効率が低下するため、一般にこれら打撃子や反撥板は着脱交換可能として設けられ、使用時間又は摩耗量が所定限度に達すると交換される。こうした従来の破砕装置の例として、特開2007−203153号公報や特開2008−86871号公報に開示されるものがある。   The striker and the repulsion plate in this conventional crushing apparatus directly collide with the object to be crushed, and thus wear with the use of the crushing apparatus. When the striker and the repellent plate are worn, the crushing efficiency of the object to be crushed decreases. Generally, the striker and the repellent plate are provided so as to be detachable and replaceable. The Examples of such conventional crushing apparatuses include those disclosed in JP 2007-203153 A and JP 2008-88671 A.

特開2007−203153号公報JP 2007-203153 A 特開2008−86871号公報JP 2008-88671 A

従来の破砕装置は前記各特許文献に示されるものであり、主な用途として、採石場等で取得された原料の石を破砕対象物として破砕し、適切な大きさの砂利や砕石を得ることが挙げられる。また、リサイクル材としての再利用のために、コンクリートがら(コンクリート廃材)やアスファルトがら(アスファルト廃材)を、破砕対象物として破砕装置で破砕し、細かい破砕片とすることも従来から多く行われている。   Conventional crushing devices are shown in the above patent documents, and as a main use, crush raw material stones obtained at quarries and the like as crushing objects to obtain gravel and crushed stones of appropriate size. Is mentioned. In addition, in order to reuse as recycled materials, it has been often done in the past to crush concrete waste (concrete waste material) and asphalt waste (asphalt waste material) as crushing objects with a crushing device to make fine pieces. Yes.

このうち、コンクリートがらやアスファルトがらについては、その廃材としての由来故に、鉄筋、鉄屑などの金属製の異物が混入していることがある。これら異物が破砕装置に投入されると、こうした金属製の異物は通常の破砕対象物である石やコンクリートに比べて硬質である分、破砕装置の打撃子や反撥板の異常な摩耗や破損を招きやすいことから、可能な限りこれら異物を投入前に除去する必要があった。   Among these, concrete debris and asphalt debris may be mixed with metal foreign matters such as reinforcing bars and scraps due to their origin as waste materials. When these foreign objects are thrown into the crushing device, these metal foreign materials are harder than stone and concrete, which are normal objects to be crushed, and will cause abnormal wear and breakage of the crushing device striker and repulsion plate. Since it is easy to invite, it was necessary to remove these foreign substances as much as possible before throwing them in.

このような金属製の異物の除去は、一般に、破砕対象物中から金属検出器等で異物を検出するようにし、異物が検出されたら、破砕装置や破砕対象物の供給用コンベヤを停止させ、作業者が手作業によって異物を取り除く、という手法で従来行われていた。   In general, the removal of such metal foreign matter is to detect the foreign matter with a metal detector or the like from the object to be crushed, and when the foreign object is detected, the crushing device and the conveyor for supplying the object to be crushed are stopped, Conventionally, an operator manually removes foreign matter.

しかしながら、こうした従来の手作業による除去では、多くの手間と労力が必要となる上、破砕装置他を停止させることで、その間は破砕が行えず、破砕作業の能率が大きく低下し、破砕に係るコストが大きくなるという課題を有していた。   However, such conventional manual removal requires a lot of labor and labor, and by stopping the crushing device etc., crushing cannot be performed during that time, and the efficiency of crushing work is greatly reduced, and The problem was that the cost would increase.

この他、従来の破砕装置では、供給用のコンベヤから投入口への破砕対象物の投入状態は特に変化せず一定であり、その結果、破砕対象物が最初に打撃子と接触する位置もほとんど変化しないことから、破砕対象物が打撃子に衝突して撥ね飛ばされる方向もほとんど変化しないこととなり、破砕対象物が打撃子や反撥板と接触、衝突する位置には偏りが生じやすかった。   In addition, in the conventional crushing device, the state of charging of the crushing object from the supply conveyor to the inlet is not particularly changed, and as a result, the crushing object first comes into contact with the striker. Since the change does not change, the direction in which the object to be crushed collides with the striker and is repelled hardly changes, and the position where the object to be crushed contacts and collides with the striker and the repellent plate is likely to be biased.

このため、打撃子や反撥板の摩耗箇所にも偏りが生じやすく、破砕対象物に硬い金属製の異物が混入しているか否かに関わりなく、装置を使用するほど打撃子や反撥板には局部的に摩耗が進行し、打撃子や反撥板の大部分で摩耗限界に満たず正常に破砕が行える状態であるにもかかわらず、一部で摩耗限界に達することで交換を余儀なくされ、装置の運転コストが余計にかかってしまうという課題を有していた。   For this reason, it is easy for the striker and the repellent plate to be worn away, and whether the hard object is mixed with the object to be crushed or not, Although wear has progressed locally and most of the impactor and repellent plate are below the wear limit and can be crushed normally, the wear limit is partially reached and replacement is forced. However, there was a problem that the operating cost would be excessive.

本発明は前記課題を解消するためになされたもので、破砕対象物を移送する各コンベヤを適切に作動させて、異物を破砕装置に投入させず、破砕装置各部の異常摩耗や破損を防止できる破砕装置用移送システムを提供することを目的とする。   The present invention has been made in order to solve the above-mentioned problems, and can appropriately operate each conveyor for transferring an object to be crushed so that foreign matters are not put into the crushing apparatus, and abnormal wear and breakage of each part of the crushing apparatus can be prevented. It aims at providing the transfer system for crushing apparatuses.

本発明に係る破砕装置用移送システムは、破砕対象物の破砕を行う破砕装置に向けて破砕対象物を移送する第一のコンベヤと、当該第一のコンベヤと破砕装置との間に、第一のコンベヤ端部から破砕対象物を載り移らせて少なくとも破砕装置側に移送可能として配設され、破砕装置寄りの一端部から破砕対象物を破砕装置の投入口側へ送り出す第二のコンベヤと、当該第二のコンベヤの作動状態について、第二のコンベヤの移送方向を破砕装置投入口に近付く向きとする順方向移送状態と、移送方向を破砕装置投入口から離れる向きとする逆方向移送状態のいずれかに切替える制御を行う制御部と、当該制御部に接続されて配設され、移送される破砕対象物に混じった異物を検出可能とされ、少なくとも異物検出時には、当該異物検出結果を含む所定の制御用情報を制御部に送出可能とされる異物検出部とを備え、前記第一のコンベヤが破砕対象物を移送すると共に、前記第二のコンベヤが順方向移送状態にあって破砕対象物を破砕装置の投入口へ向け送り出す中で、前記制御部が、前記異物検出部からの前記所定の制御用情報を受け取ると、第一のコンベヤで移送される異物が第一のコンベヤ端部から第二のコンベヤに載り移る時に、第二のコンベヤを順方向移送状態から逆方向移送状態に切替え、前記第二のコンベヤが、逆方向移送状態で異物をコンベヤ他端部から所定の排出路に送り出した時に、前記制御部が、第二のコンベヤを逆方向移送状態から順方向移送状態に切替えるものである。   The crushing device transfer system according to the present invention includes a first conveyor that transfers a crushing object toward a crushing device that crushes the crushing object, and a first conveyor between the first conveyor and the crushing device. A second conveyor for transferring a crushing object from at least one end of the crushing apparatus and transferring the crushing object from one end near the crushing apparatus to the crushing apparatus, Regarding the operating state of the second conveyor, there are a forward transfer state in which the transfer direction of the second conveyor is close to the crushing device inlet and a reverse transfer state in which the transfer direction is away from the crusher inlet. A control unit that performs control to switch to any one of the above, and a foreign object that is connected to the control unit and that is mixed in the crushing object to be transferred can be detected. And a foreign matter detection unit capable of sending predetermined control information to the control unit, the first conveyor transfers the object to be crushed, and the second conveyor is in a forward transfer state and is crushed. When the control unit receives the predetermined control information from the foreign matter detection unit while sending the object toward the inlet of the crushing device, the foreign matter transferred by the first conveyor is transferred to the first conveyor end. When the second conveyor is transferred to the second conveyor, the second conveyor is switched from the forward transfer state to the reverse transfer state, and the second conveyor discharges the foreign matter from the other end of the conveyor in the reverse transfer state. When sent to the road, the control unit switches the second conveyor from the reverse transfer state to the forward transfer state.

このように本発明によれば、移送される破砕対象物に混入した異物を異物検出部で検出すると、異物が第一のコンベヤから第二のコンベヤに載り移った時点で制御部が第二のコンベヤを順方向移送状態から逆方向移送状態に切替え、第二のコンベヤ上の異物を破砕装置の投入口とは遠ざけて排出可能とすることにより、異物を第二のコンベヤから破砕装置の投入口に投入せずに済み、異物が金属製など硬質である場合に破砕装置内部の各機構と異物との接触、衝突に基づく機構の異常な摩耗や破損を防止でき、破砕装置における摩耗する消耗部品の耐久性を高められ、消耗部品の交換頻度を減らして経済性を向上させられる。   As described above, according to the present invention, when the foreign matter mixed in the object to be crushed is detected by the foreign matter detection unit, when the foreign matter is transferred from the first conveyor to the second conveyor, the control unit By switching the conveyor from the forward transfer state to the reverse transfer state and allowing the foreign matter on the second conveyor to be discharged away from the crushing device input port, the foreign material can be discharged from the second conveyor to the crushing device input port. When the foreign matter is hard, such as metal, contact between each mechanism inside the crushing device and the foreign matter, and abnormal wear and damage of the mechanism based on the collision can be prevented. The durability of the battery can be improved, and the replacement frequency of consumable parts can be reduced to improve the economy.

また、本発明に係る破砕装置用移送システムは必要に応じて、前記制御部が、前記第二のコンベヤの移送速度を調整制御可能とされ、前記異物検出部からの前記所定の制御用情報を受け取ると、第二のコンベヤの移送速度を当初より大きくし、前記第二のコンベヤが異物をコンベヤ他端部から所定の排出路に送り出した時に、前記制御部が、第二のコンベヤを逆方向移送状態から順方向移送状態に切替えると共に、当該切替えと同時又は所定時間経過後に、当初の移送速度に戻す速度調整を行うものである。   Further, in the crushing device transfer system according to the present invention, the control unit can adjust and control the transfer speed of the second conveyor as necessary, and the predetermined control information from the foreign matter detection unit can be controlled. Upon receipt, the transfer speed of the second conveyor is increased from the beginning, and when the second conveyor sends out foreign matter from the other end of the conveyor to the predetermined discharge path, the control unit moves the second conveyor in the reverse direction. In addition to switching from the transfer state to the forward transfer state, speed adjustment is performed to return to the original transfer speed simultaneously with the change or after a predetermined time has elapsed.

このように本発明によれば、第一のコンベヤで移送される破砕対象物に混入した異物を異物検出部で検出すると、第二のコンベヤの移送速度を大きくすることにより、異物が検出されてから第一のコンベヤから第二のコンベヤに異物が載り移るまでに、第一のコンベヤから第二のコンベヤに載り移った破砕対象物の、第二のコンベヤ上における載置密度を小さくすると共に、破砕対象物の第二のコンベヤ上から破砕装置の投入口に進む割合を多くして、異物が第一のコンベヤから第二のコンベヤに載り移って第二のコンベヤが逆方向移送状態に切り替わった時点で、第二のコンベヤ上の破砕対象物の量を少なくすることができ、第二のコンベヤをよりスムーズに動かして異物を無理なく移送して排出できる上、誤って異物と共にコンベヤから排出される破砕対象物の量をできるだけ少なくして、損失を抑えて破砕をより効率よく進められる。また、第二のコンベヤ上の破砕対象物を少なくできる分、異物が排出されて第二のコンベヤが順方向移送状態に切り替わった後、第一のコンベヤから第二のコンベヤに破砕対象物が載り移っても第二のコンベヤ上の破砕対象物が過剰にならず、第一のコンベヤを一時停止させなくても第二のコンベヤによる破砕対象物の移送を無理なく継続でき、第一のコンベヤの移送に係る制御機構を簡略化してコストを抑えられる。   As described above, according to the present invention, when the foreign matter mixed in the object to be crushed transferred by the first conveyor is detected by the foreign matter detection unit, the foreign matter is detected by increasing the transfer speed of the second conveyor. From the first conveyor to the second conveyor, foreign matter is transferred from the first conveyor to the second conveyor, and the crushing object transferred from the first conveyor to the second conveyor is reduced in density on the second conveyor, Increasing the proportion of the object to be crushed from the second conveyor to the crushing device inlet, foreign matter was transferred from the first conveyor to the second conveyor, and the second conveyor was switched to the reverse transfer state. At this point, the amount of objects to be crushed on the second conveyor can be reduced, and the second conveyor can be moved more smoothly so that foreign substances can be transported and discharged more easily. And as little as possible amount of crushed objects issued, proceed more efficiently crushed while suppressing losses. Moreover, after the foreign matter is discharged and the second conveyor is switched to the forward transfer state by the amount that can reduce the objects to be crushed on the second conveyor, the objects to be crushed are placed on the second conveyor from the first conveyor. Even if it moves, the crushing object on the second conveyor does not become excessive, and even if the first conveyor is not temporarily stopped, the crushing object can be transported by the second conveyor without difficulty. The control mechanism related to the transfer can be simplified to reduce the cost.

また、本発明に係る破砕装置用移送システムは必要に応じて、前記第二のコンベヤが、前記制御部の制御に基づいて、少なくとも一端部を横方向に所定範囲移動可能とされ、前記制御部が、前記破砕装置の作動中又は作動の合間の所定タイミングで、破砕装置に対し前記第二のコンベヤの一端部を横に移動させて、第二のコンベヤの一端部から送り出される破砕対象物の破砕装置投入口における到達位置を変えるものである。   Further, in the crushing device transfer system according to the present invention, if necessary, the second conveyor can move at least one end in a lateral direction within a predetermined range based on the control of the control unit, and the control unit However, during the operation of the crushing device or at a predetermined timing between the operations, the one end of the second conveyor is moved laterally with respect to the crushing device, and the crushing object to be sent out from the one end of the second conveyor The arrival position at the crusher inlet is changed.

このように本発明によれば、破砕装置に対し所定のタイミングで第二のコンベヤの一端部を横方向に移動させて、第二のコンベヤから出る破砕対象物の破砕装置投入口における到達位置をそれまでとは異なる位置に調整できることにより、破砕装置における破砕対象物の進行状態を変えて、破砕対象物と破砕装置内各機構との衝突位置関係を変更でき、衝突位置が一部に偏らず、その結果摩耗箇所も偏りなく分散させることができ、摩耗が集中しない分、消耗部品の摩耗限界に達するまでの時間を長くし、消耗部品の交換頻度を減らして破砕装置の運転コストを低減できる。   As described above, according to the present invention, the end position of the second conveyor is moved laterally at a predetermined timing with respect to the crushing device, and the arrival position of the crushing object coming out of the second conveyor at the crushing device inlet is determined. By being able to adjust to a position different from that before, it is possible to change the collision position relationship between the crushing object and each mechanism in the crushing device by changing the progress state of the crushing object in the crushing device, and the collision position is not partially biased As a result, the wear parts can be distributed evenly, the wear is not concentrated, the time to reach the wear limit of the consumable parts is lengthened, the replacement frequency of the consumable parts is reduced, and the operating cost of the crushing device can be reduced. .

また、本発明に係る破砕装置用移送システムは必要に応じて、前記異物検出部が、前記第一のコンベヤで破砕対象物の移送を行う間、異物を検出していない場合も、異物検出結果を含まない制御用情報を前記制御部に送出し、前記制御部が、前記異物検出部からの制御用情報に基づいて、第一のコンベヤの移送実行状態を取得し、第一のコンベヤでの移送が行われる間、あらかじめ設定された所定時間が経過するごとに、当該経過時点を前記所定タイミングとして、前記第二のコンベヤの一端部の位置を順次変化させるものである。   Moreover, the crushing device transfer system according to the present invention is also capable of detecting a foreign object when the foreign object detection unit does not detect a foreign object while transferring the object to be crushed by the first conveyor. Is sent to the control unit, the control unit acquires the transfer execution state of the first conveyor based on the control information from the foreign matter detection unit, During the transfer, every time a predetermined time set in advance elapses, the position of one end of the second conveyor is sequentially changed with the elapsed time as the predetermined timing.

このように本発明によれば、異物検出部からの制御用情報に基づき、制御部で、第一のコンベヤが破砕対象物の移送を行う間、所定時間経過ごとに第二のコンベヤの一端部の位置を変化させ、第二のコンベヤから出る破砕対象物の破砕装置投入口における到達位置を順次変えていくことにより、第一のコンベヤでの移送が行われる間は破砕装置も作動状態と見なせることから、破砕装置の作動状態が続く間じゅう、破砕対象物と破砕装置内各機構との衝突位置を所定時間ごとにずらせることとなり、衝突位置を集中させず均等化して、摩耗も偏りなく均等に進行させられ、消耗部品の摩耗限界に達するまでの時間をできるだけ長くして、消耗部品をより効率よく使用してコストを抑えられる。また、破砕装置の作動状態継続に対応して所定時間経過ごとの移送状態調整を繰り返す制御を、制御部で破砕装置を直接監視することなく実現でき、制御構成を簡略化してコストダウンが図れる。   As described above, according to the present invention, based on the control information from the foreign matter detection unit, the control unit transfers one object of the second conveyor every predetermined time while the first conveyor transfers the object to be crushed. The crushing device can be considered to be in operation while it is being transferred on the first conveyor by changing the position at which the crushing object coming from the second conveyor reaches the crushing device inlet sequentially. Therefore, throughout the operation state of the crushing device, the collision position between the crushing object and each mechanism in the crushing device is shifted every predetermined time, and the collision position is equalized without concentrating and wear is not biased. Proceeding evenly, the time to reach the wear limit of the consumable parts is made as long as possible, the consumable parts can be used more efficiently and the cost can be reduced. In addition, it is possible to realize control that repeats the transfer state adjustment at every elapse of a predetermined time corresponding to the continuation of the operation state of the crushing device without directly monitoring the crushing device by the control unit, thereby simplifying the control configuration and reducing the cost.

また、本発明に係る破砕装置用移送システムは必要に応じて、前記第二のコンベヤが、前記制御部の制御に基づいて、少なくとも前記順方向移送状態における移送速度を増減調整可能とされ、前記制御部が、前記破砕装置の作動中又は作動の合間の所定タイミングで、前記第二のコンベヤの順方向移送状態における移送速度を変化させ、第二のコンベヤの一端部から送り出される破砕対象物の破砕装置投入口における到達位置を変えるものである。   The crushing device transfer system according to the present invention can adjust the transfer speed at least in the forward transfer state at least based on the control of the control unit, if necessary, The control unit changes the transfer speed in the forward transfer state of the second conveyor at a predetermined timing during the operation of the crushing device or between operations, and the crushing object to be sent out from one end of the second conveyor The arrival position at the crusher inlet is changed.

このように本発明によれば、破砕装置に対し所定のタイミングで第二のコンベヤの移送速度を変化させて、第二のコンベヤから出る破砕対象物の破砕装置投入口における到達位置をそれまでとは異なる位置に調整できることにより、破砕装置における破砕対象物の進行状態を変えて、破砕対象物と破砕装置内各機構との衝突位置関係を変更でき、衝突位置が一部に偏らず、その結果摩耗箇所も偏りなく分散させることができ、摩耗が集中しない分、消耗部品の摩耗限界に達するまでの時間を長くし、消耗部品の交換頻度を減らして破砕装置の運転コストを低減できる。   As described above, according to the present invention, the transfer speed of the second conveyor is changed at a predetermined timing with respect to the crushing apparatus, and the arrival position of the crushing object coming out of the second conveyor at the crushing apparatus input port is changed to that. Can be adjusted to different positions, changing the advancing state of the crushing object in the crushing device, changing the collision position relationship between the crushing object and each mechanism in the crushing device, and the collision position is not partially biased, Wear parts can be distributed evenly, and the amount of time that it takes to reach the wear limit of consumable parts can be lengthened, and the operating cost of the crushing apparatus can be reduced by reducing the frequency of replacement of consumable parts.

また、本発明に係る破砕装置用移送システムは必要に応じて、前記異物検出部が、前記第一のコンベヤで破砕対象物の移送を行う間、異物を検出していない場合も、異物検出結果を含まない制御用情報を前記制御部に送出し、前記制御部が、前記異物検出部からの制御用情報に基づいて、第一のコンベヤの移送実行状態を取得し、第一のコンベヤでの移送が行われる間、あらかじめ設定された所定時間が経過するごとに、当該経過時点を前記所定タイミングとして、前記第二のコンベヤの順方向移送状態における移送速度を順次変化させるものである。   Moreover, the crushing device transfer system according to the present invention is also capable of detecting a foreign object when the foreign object detection unit does not detect a foreign object while transferring the object to be crushed by the first conveyor. Is sent to the control unit, the control unit acquires the transfer execution state of the first conveyor based on the control information from the foreign matter detection unit, During the transfer, every time a predetermined time set in advance elapses, the transfer speed in the forward transfer state of the second conveyor is sequentially changed with the elapsed time as the predetermined timing.

このように本発明によれば、異物検出部からの制御用情報に基づき、制御部で、第一のコンベヤが破砕対象物の移送を行う間、所定時間経過ごとに第二のコンベヤの移送速度を変化させ、第二のコンベヤから出る破砕対象物の破砕装置投入口における到達位置を順次変えていくことにより、第一のコンベヤでの移送が行われる間は破砕装置も作動状態と見なせることから、破砕装置の作動状態が続く間じゅう、破砕対象物と破砕装置内各機構との衝突位置を所定時間ごとにずらせることとなり、衝突位置を集中させず均等化して、摩耗も偏りなく均等に進行させられ、消耗部品の摩耗限界に達するまでの時間をできるだけ長くして、消耗部品をより効率よく使用してコストを抑えられる。また、破砕装置の作動状態継続に対応して所定時間経過ごとの移送状態調整を繰り返す制御を、制御部で破砕装置を直接監視することなく実現でき、制御構成を簡略化してコストダウンが図れる。   As described above, according to the present invention, based on the control information from the foreign matter detection unit, the transfer rate of the second conveyor every predetermined time while the first conveyor transfers the object to be crushed in the control unit. By changing the arrival position of the object to be crushed from the second conveyor at the inlet of the crushing device, the crushing device can be regarded as operating while it is being transferred on the first conveyor. During the operation of the crushing device, the collision position between the crushing object and each mechanism in the crushing device is shifted every predetermined time, and the collision position is equalized without concentrating, and the wear is evenly distributed. The time until the wear limit of the consumable parts is reached is made as long as possible, and the consumable parts can be used more efficiently to reduce the cost. In addition, it is possible to realize control that repeats the transfer state adjustment at every elapse of a predetermined time corresponding to the continuation of the operation state of the crushing device without directly monitoring the crushing device by the control unit, thereby simplifying the control configuration and reducing the cost.

また、本発明に係る破砕装置用移送システムは必要に応じて、前記破砕装置の投入口を取り囲むように配設され、上部に設けられた開口部分近傍に前記第二のコンベヤの一端部を位置させ、当該一端部を出た破砕対象物を破砕装置の投入口に案内する案内部と、当該案内部内における第二のコンベヤの一端部と破砕装置の投入口の間に上部を支持された吊り下げ状態で複数配設され、前記第二のコンベヤの一端部を出た破砕対象物と接触可能とされる所定長さの吊下体と、前記案内部に前記各吊下体一端部と連結させた状態として配設され、前記制御部の制御に基づいて、吊下体一端部を変位させて吊下体の吊り下げ長さを調整可能とする複数のアクチュエータとを備え、前記吊下体が、横方向に複数の組に分けられ、当該複数の組ごとにそれぞれ前記アクチュエータで吊り下げ長さを調整可能とされてなり、横方向の一側にある一又は複数組の吊下体と、横方向の他側にある一又は複数組の吊下体とで、アクチュエータの作動状態を異ならせて吊下体の吊り下げ長さが相違する状態とされ、前記制御部が、前記破砕装置の作動中又は作動の合間の所定タイミングで、前記アクチュエータを作動させて前記一側の吊下体と他側の吊下体との吊り下げ長さの関係を入れ替えるように変化させ、吊下体と破砕対象物との接触状態を前記一側の吊下体と他側の吊下体とで変えて、第二のコンベヤの一端部から送り出される破砕対象物の破砕装置投入口における到達位置を変えるものである。   Further, the crushing device transfer system according to the present invention is disposed so as to surround the inlet of the crushing device as necessary, and one end portion of the second conveyor is positioned in the vicinity of the opening provided in the upper portion. A guide unit that guides the object to be crushed from the one end to the input port of the crushing device, and a suspension supported at an upper portion between the one end of the second conveyor and the input port of the crushing device in the guide unit. A plurality of suspended bodies that are arranged in a lowered state and that can be brought into contact with the object to be crushed from the one end of the second conveyor, and one end of each suspended body is connected to the guide section. A plurality of actuators that are arranged in a state and that are capable of adjusting the suspension length of the suspension body by displacing one end portion of the suspension body based on the control of the control unit, wherein the suspension body is arranged in the lateral direction. Divided into multiple groups, and The suspension length can be adjusted by the actuator, and one or more sets of suspension bodies on one side in the horizontal direction and one or more sets of suspension bodies on the other side in the lateral direction, The operating state of the actuator is made different so that the hanging lengths of the suspended bodies are different, and the control unit operates the actuator at a predetermined timing during the operation of the crushing device or between the operations. The relationship between the suspended length of the suspended body on the other side and the suspended body on the other side is changed so that the contact state between the suspended body and the object to be crushed is the same between the suspended body on the one side and the suspended body on the other side. In other words, the arrival position at the crushing device inlet of the crushing object fed from one end of the second conveyor is changed.

このように本発明によれば、破砕装置の投入口を取り囲む案内部に、コンベヤを出た破砕対象物と接触する吊下体を吊り下げ長さ調整可能として複数組配設すると共に、横方向の一側と他側で吊下体の吊り下げ長さを異ならせ、破砕装置に対し所定のタイミングで横方向の一側と他側における吊下体の吊り下げ長さの関係を入れ替えて、コンベヤを出た破砕対象物と吊下体との接触状態を変化させることにより、破砕対象物の破砕装置投入口における到達位置をそれまでとは異なる位置に調整できることとなり、破砕装置における破砕対象物の進行状態を変えて、破砕対象物と破砕装置内各機構との衝突位置関係を変更でき、衝突位置が一部に偏らず、その結果摩耗箇所も偏りなく分散させることができ、摩耗が集中しない分、消耗部品の摩耗限界に達するまでの時間を長くし、消耗部品の交換頻度を減らして破砕装置の運転コストを低減できる。   As described above, according to the present invention, a plurality of sets of suspension bodies that come into contact with the object to be crushed from the conveyor are arranged in the guide portion that surrounds the inlet of the crushing apparatus so that the suspension length can be adjusted, and the lateral direction is adjusted. Change the hanging length of the suspended body on one side and the other side, and swap the relationship between the suspended length of the suspended body on the one side and the other side in the horizontal direction at a predetermined timing with respect to the crushing device. By changing the contact state between the object to be crushed and the suspended body, the arrival position of the object to be crushed at the crushing device inlet can be adjusted to a position different from the previous position, and the progress state of the object to be crushed in the crushing device can be adjusted. By changing the collision position relationship between the object to be crushed and each mechanism in the crushing device, the collision position is not partially biased, and as a result, wear points can be evenly distributed, and wear is not concentrated. Parts wear A longer time to reach the limit, can be reduced operating costs of the crushing apparatus to reduce the frequency of replacement of consumable parts.

また、本発明に係る破砕装置用移送システムは、破砕対象物の破砕を行う破砕装置に向けて破砕対象物を移送し、破砕装置寄りの端部から破砕対象物を破砕装置の投入口側へ送り出す一又は複数のコンベヤと、前記破砕装置の投入口を取り囲むように配設され、上部に設けられた開口部分近傍に前記コンベヤの最も破砕装置寄りの一端部を位置させ、当該一端部を出た破砕対象物を破砕装置の投入口に案内する案内部と、当該案内部における前記破砕装置の投入口側方で且つコンベヤの前記一端部の下方となる所定箇所で案内部内に連通して配設される異物排出用の排出路と、前記案内部内における、コンベヤの前記一端部と破砕装置の投入口との間の第一の所定位置から、コンベヤの前記一端部と前記排出路との間の第二の所定位置までの角度範囲で少なくとも傾動可能に配設される略板状の切替ダンパーと、前記切替ダンパーを傾動させて、切替ダンパーが前記第二の所定位置にあって破砕対象物が前記投入口のみに進行可能な通常投入状態と、切替ダンパーが前記第一の所定位置にあって異物が前記排出路のみに進行可能な異物排出状態とを切替える制御を行う制御部と、当該制御部に接続されて配設され、前記コンベヤで移送される破砕対象物に混じった異物を検出可能とされ、少なくとも異物検出時には、当該異物検出結果を含む所定の制御用情報を制御部に送出可能とされる異物検出部とを備え、前記切替ダンパーが前記通常投入状態にある中で、前記制御部が、前記異物検出部からの前記所定の制御用情報を受け取ると、コンベヤで移送される異物が前記一端部を出る時に、前記切替ダンパーを傾動させて前記通常投入状態から異物排出状態に切替え、前記制御部が、異物が前記排出路に入った時に、前記切替ダンパーを傾動させて前記異物排出状態から通常投入状態に切替えるものである。   Further, the crushing device transfer system according to the present invention transfers the crushing object toward a crushing device that crushes the crushing object, and moves the crushing object from the end near the crushing device to the inlet side of the crushing device. One or a plurality of conveyors to be sent out and an inlet of the crushing device are arranged so as to surround one end portion of the conveyor closest to the crushing device in the vicinity of the opening provided in the upper portion, and the one end portion is ejected. A guide unit that guides the crushed object to the inlet of the crushing device, and a guide portion that communicates with the guide unit at a predetermined position on the side of the crushing device and below the one end of the conveyor. From a first predetermined position between the one end of the conveyor and the inlet of the crushing device in the guide section, between the one end of the conveyor and the discharge path. Up to the second predetermined position A substantially plate-shaped switching damper disposed so as to be tiltable at least within a range of degrees, and tilting the switching damper so that the switching damper is in the second predetermined position and the object to be crushed can advance only to the inlet A control unit for controlling switching between a normal charging state and a foreign matter discharge state in which the switching damper is in the first predetermined position and foreign matter can travel only to the discharge path, and connected to the control unit. A foreign matter detection unit capable of detecting foreign matter mixed in the object to be crushed transferred by the conveyor, and capable of sending predetermined control information including the foreign matter detection result to the control unit at least when foreign matter is detected. When the control unit receives the predetermined control information from the foreign matter detection unit while the switching damper is in the normal input state, the foreign matter transferred by the conveyor comes out of the one end portion. Sometimes, the switching damper is tilted to switch from the normal input state to the foreign matter discharge state, and when the foreign matter enters the discharge path, the control unit tilts the switching damper to normal discharge state from the foreign matter discharge state. Is switched to.

このように本発明によれば、移送される破砕対象物に混入した異物を異物検出部で検出すると、異物がコンベヤの前記一端部を出た時点で、制御部が切替ダンパーを通常投入状態から異物排出状態に切替え、案内部内で落下する異物を破砕装置の投入口ではなく排出路に向かわせて排出可能とすることにより、異物を破砕装置の投入口に投入せずに済み、異物が金属製など硬質である場合に破砕装置内部の各機構と異物との接触、衝突に基づく機構の異常な摩耗や破損を防止でき、破砕装置における摩耗する消耗部品の耐久性を高められ、消耗部品の交換頻度を減らして経済性を向上させられる。   As described above, according to the present invention, when the foreign matter mixed in the object to be crushed is detected by the foreign matter detection unit, the control unit removes the switching damper from the normal input state when the foreign matter exits the one end of the conveyor. By switching to the foreign matter discharge state and allowing foreign matter falling in the guide to be discharged toward the discharge path instead of the crushing device inlet, it is not necessary to put the foreign material into the inlet of the crushing device. When it is hard, the contact between each mechanism inside the crushing device and foreign matter, the abnormal wear and damage of the mechanism based on the collision can be prevented, the durability of the consumable parts worn in the crushing device can be improved, and Economics can be improved by reducing replacement frequency.

(本発明の第1の実施形態)
以下、本発明の第1の実施形態に係る破砕装置用移送システムを前記図1ないし図10に基づいて説明する。本実施形態においては、破砕装置がインパクトクラッシャである例について説明する。
前記各図において本実施形態に係る破砕装置用移送システム1は、破砕装置10に向けて破砕対象物90を移送する第一のコンベヤ20と、この第一のコンベヤ20端部から破砕対象物90を載り移らせて破砕装置10側に移送可能として配設される第二のコンベヤ30と、この第二のコンベヤ30の作動状態を切替える制御を行う制御部40と、第一のコンベヤ20で移送される破砕対象物90に混じった異物91を検出可能とされる異物検出部50と、破砕装置10の投入口15を取り囲むように配設される案内部60とを備える構成である。
(First embodiment of the present invention)
Hereinafter, the crushing device transfer system according to the first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, an example in which the crushing device is an impact crusher will be described.
In each of the drawings, the crushing device transfer system 1 according to the present embodiment includes a first conveyor 20 that transfers a crushing object 90 toward the crushing device 10 and a crushing object 90 from the end of the first conveyor 20. Is transferred by the second conveyor 30 that can be transferred to the crushing apparatus 10 side, a control unit 40 that performs control for switching the operation state of the second conveyor 30, and the first conveyor 20. In this configuration, the foreign matter detection unit 50 capable of detecting the foreign matter 91 mixed in the crushing object 90 to be detected and the guide unit 60 disposed so as to surround the inlet 15 of the crushing device 10 are provided.

前記破砕装置10は、ケーシング11内部で回転可能に支持されるロータ12と、このロータ12の外周に複数突設されてロータ12と一体に回転する打撃子13と、ケーシング11内部におけるロータ12及び打撃子13の周囲に設置されて固定状態とされる複数の反撥板14とを備えて、投入された破砕対象物90を打撃子13に衝突させたり、打撃子13に当たって撥ね飛ばされた破砕対象物90をさらに反撥板14に衝突させて破砕するものである。破砕装置各部の機構については、インパクトクラッシャとして公知の破砕装置と同様のものであり、詳細な説明を省略する。   The crushing device 10 includes a rotor 12 that is rotatably supported inside a casing 11, a plurality of striking members 13 that protrude from the outer periphery of the rotor 12 and rotate integrally with the rotor 12, a rotor 12 inside the casing 11, A plurality of repulsion plates 14 that are installed around the hitting element 13 and are fixed. The crushing object 90 that is thrown into the hitting element 13 collides with the hitting element 13 or is shattered off by hitting the hitting element 13. The object 90 is further crushed by colliding with the repulsion plate 14. About the mechanism of each part of the crushing apparatus, it is the same as that of a known crushing apparatus as an impact crusher, and detailed description is abbreviate | omitted.

前記第一のコンベヤ20は、破砕対象物90の破砕を行う破砕装置10に向けて破砕対象物90を移送するものである。コンベヤ自体の構造は公知のベルトコンベヤと同様のものであり、詳細な説明を省略する。ただし、この第一のコンベヤはベルトコンベヤに限られるものではなく、破砕対象物の移送機能を有するものであれば、スクリューコンベヤや振動コンベヤ(振動フィーダ)など、他の移送手段でもかまわない。   The first conveyor 20 transports the crushing object 90 toward the crushing apparatus 10 that crushes the crushing object 90. The structure of the conveyor itself is the same as that of a known belt conveyor, and detailed description thereof is omitted. However, the first conveyor is not limited to the belt conveyor, and may be other transfer means such as a screw conveyor or a vibrating conveyor (vibrating feeder) as long as it has a function of transferring the object to be crushed.

前記第二のコンベヤ30は、第一のコンベヤ20と破砕装置10との間に、第一のコンベヤ20端部から破砕対象物90を載り移らせて少なくとも破砕装置側に移送可能として配設され、破砕装置寄りの一端部から破砕対象物90を破砕装置10の投入口15側へ送り出す構成である。そして、第二のコンベヤ30は、破砕対象物90の移送方向を破砕装置投入口15に近付く向きとする順方向移送状態と、移送方向を破砕装置投入口15から離れる向きとする逆方向移送状態にそれぞれ切替可能とされる。   The second conveyor 30 is arranged between the first conveyor 20 and the crushing device 10 so that the crushing object 90 is transferred from the end of the first conveyor 20 and can be transferred to at least the crushing device side. In this configuration, the object to be crushed 90 is sent out from the one end near the crushing apparatus to the inlet 15 side of the crushing apparatus 10. Then, the second conveyor 30 has a forward transfer state in which the transfer direction of the crushing object 90 is close to the crushing device input port 15 and a reverse transfer state in which the transfer direction is a direction away from the crushing device input port 15. Each can be switched.

この第二のコンベヤ30についても、コンベヤ自体の構造は公知の正逆転切替可能なベルトコンベヤと同様のものであり、詳細な説明を省略する。ただし、この第二のコンベヤも、ベルトコンベヤに限られるものではなく、破砕対象物の正逆二方向への移送機能を有するものであれば、振動コンベヤ(振動フィーダ)や重力式コンベヤ、シューターなど、他の移送手段でもかまわない。   The structure of the conveyor itself of the second conveyor 30 is the same as that of a known belt conveyor capable of switching between normal and reverse rotation, and detailed description thereof is omitted. However, this second conveyor is not limited to a belt conveyor, and if it has a function of transferring objects to be crushed in two directions, a vibrating conveyor (vibrating feeder), a gravity conveyor, a shooter, etc. Other transfer means may be used.

この第二のコンベヤ30は、破砕装置10寄りの一端部を横方向に所定範囲移動可能とするように支持されており、制御部40の制御に基づくアクチュエータ31の作動によって、破砕装置10に対し一端部を横移動させて位置調整される構成である。第二のコンベヤ30の一端部を横方向に位置調整することで、この第二のコンベヤ30の一端部から送り出される破砕対象物90の破砕装置投入口15における到達位置を横方向に変えることができる(図4参照)。   The second conveyor 30 is supported so that one end near the crushing device 10 can move in a predetermined range in the lateral direction, and the actuator 31 is operated based on the control of the control unit 40 to the crushing device 10. The position is adjusted by laterally moving one end. By adjusting the position of one end portion of the second conveyor 30 in the horizontal direction, the arrival position of the crushing object 90 fed from the one end portion of the second conveyor 30 at the crushing device inlet 15 can be changed in the horizontal direction. Yes (see FIG. 4).

なお、第二のコンベヤ30については、破砕装置10寄りの一端部を横方向に移動可能となるよう支持する構成としているが、これに限らず、一端部に代えて破砕装置10から離れた他端部を横方向に移動可能とするよう支持し、所定のアクチュエータでこの他端部を横に動かすことで破砕対象物の移送方向を変え、破砕装置に投入される破砕対象物の破砕装置投入口15における到達位置を横にずらす構成とすることもできる。
第二のコンベヤ30の他端部近傍下側には、第二のコンベヤ30端部から出た異物91を受けて排出する排出路32が設けられる。
In addition, about the 2nd conveyor 30, although it is set as the structure supported so that the one end part near the crushing apparatus 10 may be moved to a horizontal direction, it is not restricted to this, The other which was separated from the crushing apparatus 10 instead of one end part Support the end to be movable in the horizontal direction, move the other end sideways with a predetermined actuator to change the transfer direction of the object to be shredded, and load the shredder into the shredder The reaching position at the mouth 15 may be shifted laterally.
On the lower side near the other end of the second conveyor 30, a discharge path 32 that receives and discharges the foreign matter 91 that has come out from the end of the second conveyor 30 is provided.

前記制御部40は、第二のコンベヤ30の作動状態について、第二のコンベヤ30の移送方向を破砕装置10の投入口15に近付く向きとする順方向移送状態と、移送方向を破砕装置投入口15から離れる向きとする逆方向移送状態のいずれかに切替える制御を行う構成である。   The control unit 40 has a forward transfer state in which the transfer direction of the second conveyor 30 approaches the input port 15 of the crushing device 10 and a transfer direction of the crushing device input port. 15 is configured to perform control to switch to one of the reverse transfer states in a direction away from 15.

詳細には、制御部40は、異物検出部50で異物91が検出されると、第一のコンベヤ20で移送される異物91が第一のコンベヤ20端部から第二のコンベヤ30に載り移る時に、第二のコンベヤ30を順方向移送状態から逆方向移送状態に切替える仕組みである。そして、逆方向移送状態とされた第二のコンベヤ30が、異物91をコンベヤ他端部から排出路32に送り出すと、制御部40は第二のコンベヤ30を逆方向移送状態から順方向移送状態に再び切替える。   Specifically, when the foreign object 91 is detected by the foreign object detection unit 50, the control unit 40 transfers the foreign object 91 transferred by the first conveyor 20 from the end of the first conveyor 20 to the second conveyor 30. At times, the second conveyor 30 is switched from the forward transfer state to the reverse transfer state. And if the 2nd conveyor 30 made into the reverse transfer state sends out the foreign material 91 from the other end part of the conveyor to the discharge path 32, the control unit 40 moves the second conveyor 30 from the reverse transfer state to the forward transfer state. Switch again.

この他、制御部40は、第二のコンベヤ30の移送速度を調整制御可能とされる。詳細には、制御部40は、異物検出部50からの前記所定の制御用情報を受け取ると、第二のコンベヤ30の移送速度を当初より大きくする制御を行う。その後の第二のコンベヤ30を順方向移送状態から逆方向移送状態に切替える際も、前に当初値より大きくした際の速度の大きさ(絶対値)をそのまま目標値として、移送方向を切り替えると共に速度の調整制御を行う。そして、制御部40は、第二のコンベヤ30が異物をコンベヤ他端部から排出路32に送り出した時に、第二のコンベヤ30を逆方向移送状態から順方向移送状態に切替える制御を実行するが、この場合も直前の移送速度の大きさを切替後の目標値として移送方向を切り替えると共に速度調整を行う。制御部40は、この移送方向の切替えから所定時間経過後に、第二のコンベヤ30を当初の移送速度に戻す速度調整を実行することで、第二のコンベヤ30を異物の検出がない通常の移送状態に復帰させる。   In addition, the control unit 40 can adjust and control the transfer speed of the second conveyor 30. Specifically, when receiving the predetermined control information from the foreign object detection unit 50, the control unit 40 performs control to increase the transfer speed of the second conveyor 30 from the beginning. When switching the second conveyor 30 thereafter from the forward transfer state to the reverse transfer state, the transfer direction is switched with the magnitude of the speed (absolute value) when previously increased from the initial value as it is as the target value. Performs speed adjustment control. And the control part 40 performs control which switches the 2nd conveyor 30 from a reverse transfer state to a forward transfer state, when the 2nd conveyor 30 sends out a foreign material to the discharge path 32 from the other end part of the conveyor. In this case as well, the transfer direction is switched and the speed is adjusted with the previous transfer speed as the target value after switching. The control unit 40 performs a speed adjustment for returning the second conveyor 30 to the original transfer speed after a lapse of a predetermined time from the switching of the transfer direction, thereby causing the second conveyor 30 to perform normal transfer without detecting foreign matter. Return to the state.

また、制御部40は、破砕装置10の作動中又は作動の合間の所定タイミングで、破砕装置に対し第二のコンベヤ30の一端部を横に移動させて、第二のコンベヤ30の一端部から送り出される破砕対象物90の破砕装置投入口15における到達位置をそれ以前の位置から変化させるよう制御を行う。詳細には、破砕装置10が作動してあらかじめ設定された所定時間が経過するごとに、この経過時点を前記所定タイミングとして、第二のコンベヤ30の一端部の横方向位置を順次入れ替えるように変化させる。   Moreover, the control part 40 moves one end part of the 2nd conveyor 30 sideways with respect to the crushing apparatus at the predetermined timing during the operation | movement of the crushing apparatus 10, or between operations, and from the one end part of the 2nd conveyor 30. Control is performed so that the arrival position of the crushing object 90 to be sent out at the crushing device inlet 15 is changed from the previous position. In detail, every time a predetermined time set in advance after the crushing device 10 is operated, the elapsed time is set to the predetermined timing so that the lateral position of one end of the second conveyor 30 is sequentially changed. Let

制御部40で、第二のコンベヤ30の一端部の横方向位置を変化させるタイミングを規定する前記所定時間は、破砕装置10の打撃子や反撥板等の消耗部品である程度の摩耗が見込める時間経過に対応するようにあらかじめ設定される。この他、破砕装置の各消耗部品の摩耗度合いを直接センサ等で検出して、所定の摩耗量に達したら、そのタイミングで第二のコンベヤ30の一端部の横方向位置を変化させるようにしてもかまわない。   The predetermined time that defines the timing of changing the lateral position of the one end of the second conveyor 30 by the control unit 40 is a time lapse in which a certain amount of wear can be expected from consumable parts such as a striker and a repellent plate of the crushing device 10. Is set in advance to correspond to In addition, the degree of wear of each consumable part of the crushing device is directly detected by a sensor or the like, and when the predetermined wear amount is reached, the lateral position of one end of the second conveyor 30 is changed at that timing. It doesn't matter.

前記異物検出部50は、制御部40に接続されて第一のコンベヤ20上に配設され、第一のコンベヤ20で移送される破砕対象物90に混じった金属製の異物91を検出可能とされ、少なくとも異物検出時には、この異物検出結果を含む所定の制御用情報を制御部40に送出する構成である。異物を検出する仕組みは、電磁誘導等を用いる公知の金属検出機と同様のものであり、詳細な説明を省略する。   The foreign matter detection unit 50 is connected to the control unit 40 and is disposed on the first conveyor 20, and can detect a metallic foreign matter 91 mixed in the crushing object 90 transferred by the first conveyor 20. At least when a foreign object is detected, predetermined control information including this foreign object detection result is sent to the control unit 40. The mechanism for detecting a foreign object is the same as that of a known metal detector using electromagnetic induction or the like, and detailed description thereof is omitted.

なお、異物検出部は一つに限られるものではなく、複数配設することもでき、配設箇所も第一のコンベヤ上に限られず、他の位置に設けるようにしてもよい。特に、異物検出部を複数設ける場合、金属検出機以外のセンサ等を検出部として用いて、破砕装置に影響を与えうる金属以外の異物を検出可能とすることもできる。また、異物の検出対象箇所についても、第一コンベヤだけでなく、第一コンベヤからの載り移り箇所をはじめとする、第二コンベヤやその近傍とすることもできる。例えば、第一のコンベヤからの載り移り直後の第二のコンベヤ上を検出対象として、少し離れた位置からビデオカメラ等の撮像手段で破砕対象物他の画像を取得し、画像解析等の検出手法により異物を検出するようにしてもよく、コンベヤを載り移る際に破砕対象物との位置関係が変化して表面にあらわれることも多い異物をより適切に検出できる。こうした異物検出部による異物検出の際、検出精度を向上させるため、検出対象の異物の動きが小さくなるよう、コンベヤの移送速度を低減したり、コンベヤを一時停止させることもできる。   Note that the number of foreign matter detection units is not limited to one, and a plurality of foreign matter detection units may be provided, and the arrangement location is not limited to the first conveyor, but may be provided at other positions. In particular, when a plurality of foreign matter detection units are provided, it is possible to detect foreign matters other than metal that can affect the crushing device by using a sensor other than a metal detector as the detection unit. Also, the foreign object detection target location can be not only the first conveyor but also the second conveyor and its vicinity including the transfer location from the first conveyor. For example, a detection method such as image analysis by acquiring an image of a crushing object or the like with an imaging means such as a video camera from a position slightly away from a second conveyor immediately after transfer from the first conveyor as a detection target It is possible to detect foreign matters, and it is possible to more appropriately detect foreign matters that often appear on the surface due to changes in the positional relationship with the object to be crushed when the conveyor is transferred. In order to improve the detection accuracy when detecting the foreign matter by the foreign matter detection unit, the transfer speed of the conveyor can be reduced or the conveyor can be temporarily stopped so that the movement of the foreign matter to be detected becomes small.

この異物検出部50は、第一のコンベヤ20で破砕対象物90の移送を行う間、異物91を検出していない場合も、異物検出結果を含まない別の制御用情報を制御部40に送出する構成である。   The foreign matter detection unit 50 sends another control information not including the foreign matter detection result to the control unit 40 even when the foreign matter 91 is not detected during the transfer of the crushing object 90 by the first conveyor 20. It is the structure to do.

この異物検出部50からの制御用情報に基づいて、制御部40が第一のコンベヤ20の移送実行状態を取得する。第一のコンベヤ20の作動は破砕装置10の作動と対応しており、第一のコンベヤ20での移送が行われる間は破砕装置10も作動状態と見なせることから、制御部40は第一のコンベヤ20の移送実行状態から間接的に破砕装置10の作動の有無を判断でき、破砕装置10の作動状態に応じて適切に、第二のコンベヤ30の一端部の位置調整制御を行える仕組みである。   Based on the control information from the foreign object detection unit 50, the control unit 40 acquires the transfer execution state of the first conveyor 20. The operation of the first conveyor 20 corresponds to the operation of the crushing device 10, and the crushing device 10 can be regarded as operating while the transfer on the first conveyor 20 is performed. Whether or not the crushing device 10 is operated indirectly can be determined from the transfer execution state of the conveyor 20, and the position adjustment control of one end of the second conveyor 30 can be appropriately performed according to the operation state of the crushing device 10. .

前記案内部60は、略筒状として破砕装置10の投入口15を取り囲むように配設され、上部に設けられた開口部分近傍に前記第二のコンベヤ30の一端部を位置させ、この一端部を出た破砕対象物90を破砕装置10の投入口15に案内する構成である。   The guide portion 60 is arranged in a substantially cylindrical shape so as to surround the inlet 15 of the crushing apparatus 10, and one end portion of the second conveyor 30 is positioned in the vicinity of the opening provided in the upper portion. It is the structure which guides the crushing object 90 which came out to the inlet 15 of the crushing apparatus 10.

この案内部60と共に、案内部60内における第二のコンベヤ30の一端部と破砕装置10の投入口15の間に上部を支持された吊り下げ状態とされる吊下体としてのチェーン70が複数配設される。さらに、案内部60には、各チェーン70一端部と連結させた状態とされる複数のアクチュエータ80が配設される。   Along with this guide part 60, a plurality of chains 70 as suspension bodies in which the upper part is supported between the one end part of the second conveyor 30 in the guide part 60 and the inlet 15 of the crushing device 10 are arranged. Established. Further, the guide unit 60 is provided with a plurality of actuators 80 that are connected to one end of each chain 70.

なお、案内部60下部には、排出路61と、破砕対象物90の進路を切替える切替ダンパー(図示を省略)とが設けられ、異物91が誤って案内部60に進入した場合、切替ダンパーを切り替えて異物91を投入口15ではなく排出路61に進行させる仕組みである。   Note that a discharge path 61 and a switching damper (not shown) for switching the path of the object to be crushed 90 are provided at the lower part of the guide part 60, and when the foreign matter 91 enters the guide part 60 by mistake, In this mechanism, the foreign matter 91 is switched to advance to the discharge path 61 instead of the input port 15.

前記チェーン70は、金属製の環体を多数連結させて破砕対象物90と衝突しても破損しない強度とされる所定長さの鎖であり、案内部60内における第二のコンベヤ30の一端部と破砕装置10の投入口15の間に上部を支持された吊り下げ状態で複数配設される構成である。チェーン70は、その中間部分所定位置を案内部60に架設された支持部62に掛けると共に、チェーン一端部を支持部62側方のアクチュエータ80に連結されることで、吊り下げ長さを調整可能な状態として支持部62から下方に吊り下げられた配置構成をなしている。   The chain 70 is a chain of a predetermined length that is connected to a large number of metal rings and does not break even if it collides with the object 90 to be crushed, and is one end of the second conveyor 30 in the guide section 60. It is the structure arrange | positioned in the suspended state by which the upper part was supported between the insertion part and the inlet 15 of the crushing apparatus 10. FIG. The chain 70 is hung at a predetermined position in the middle part thereof on a support part 62 installed on the guide part 60, and one end part of the chain is connected to an actuator 80 on the side of the support part 62, so that the suspension length can be adjusted. In such a state, the arrangement is suspended from the support portion 62 downward.

また、チェーン70は、第二のコンベヤ30の一端部と破砕装置10の投入口15の間に複数並べてカーテン状に配設されることで、第二のコンベヤ30の一端部を出た破砕対象物90と必要に応じて接触可能とされると共に、破砕装置10のケーシング内部で撥ね飛ばされた破砕対象物90が投入口15から外に飛び出すのを防止する仕組みである。   Further, the chain 70 is arranged in a curtain shape between the one end portion of the second conveyor 30 and the inlet 15 of the crushing device 10, so that the object to be crushed from the one end portion of the second conveyor 30. The mechanism 90 is configured to be able to come into contact with the object 90 as necessary, and to prevent the object 90 to be shattered inside the casing of the crushing apparatus 10 from jumping out from the input port 15.

前記アクチュエータ80は、案内部60に前記各チェーン70一端部とそれぞれ連結させた状態として複数配設され、制御部40の制御に基づいて、チェーン一端部を変位させてチェーン70の吊り下げ長さを調整可能とするものである。このアクチュエータ80の構造自体は、外部から導入される液体圧力でプランジャを進退させる公知の流体圧シリンダであり、詳細な説明を省略する。この流体圧シリンダをなすアクチュエータ80のプランジャに、チェーン70の一端部が連結されることで、チェーン70一端部位置を移動させてチェーン70の吊り下げ長さを調整できる仕組みである。   A plurality of the actuators 80 are arranged in a state where they are connected to one end of each chain 70 in the guide part 60, and the chain 70 is suspended by suspending the chain 70 based on the control of the control unit 40. Can be adjusted. The structure of the actuator 80 is a known fluid pressure cylinder that moves the plunger back and forth with liquid pressure introduced from the outside, and detailed description thereof is omitted. By connecting one end of the chain 70 to the plunger of the actuator 80 constituting the fluid pressure cylinder, the position of the one end of the chain 70 can be moved to adjust the hanging length of the chain 70.

次に、前記構成に基づく破砕装置用移送システムの使用状態について説明する。前提として、破砕装置10の破砕に係る作動に対応して、第一のコンベヤ20の破砕装置10から離れた側の端部に、図示しない供給手段により破砕対象物90が供給されており、破砕装置10で継続して破砕対象物90の破砕が行える状況にあるものとする。   Next, the use state of the crushing device transfer system based on the above configuration will be described. As a premise, corresponding to the operation related to crushing of the crushing device 10, the crushing object 90 is supplied to the end of the first conveyor 20 on the side away from the crushing device 10 by a supply means (not shown). It is assumed that the device 10 can continuously crush the crushing object 90.

破砕装置10の破砕に係る作動に対応して、第一のコンベヤ20も作動し、破砕装置10に向けて破砕対象物90を移送する。第一のコンベヤ20上に設けられた異物検出部50が、移送される破砕対象物中から異物を検出できない場合には、第一のコンベヤ20と破砕装置10との間にある第二のコンベヤ30に、第一のコンベヤ20端部から破砕対象物90が落下して載り移り、移送方向を破砕装置投入口15に近付く向きとする順方向移送状態にある第二のコンベヤ30により、破砕対象物90は破砕装置側に移送される。そして、第二のコンベヤ30における破砕装置寄りの一端部から、破砕対象物は落下し、案内部60内のチェーン70のある領域を経て破砕装置10の投入口15へ向かう。   Corresponding to the operation related to crushing of the crushing device 10, the first conveyor 20 is also operated to transfer the crushing object 90 toward the crushing device 10. When the foreign matter detection unit 50 provided on the first conveyor 20 cannot detect foreign matter from the crushing object to be transferred, the second conveyor located between the first conveyor 20 and the crushing device 10. 30, the crushing object 90 drops and is transferred from the end of the first conveyor 20, and the crushing object is crushed by the second conveyor 30 in the forward transfer state in which the transfer direction is close to the crushing device inlet 15. The object 90 is transferred to the crusher side. Then, the object to be crushed falls from one end of the second conveyor 30 near the crushing device, and travels to the inlet 15 of the crushing device 10 through a region where the chain 70 is located in the guide unit 60.

破砕装置10では、公知のインパクトクラッシャ同様に、投入口15からケーシング11内部に投入された破砕対象物90を、ロータ12と一体に回転する打撃子13に衝突させたり、打撃子13に当たって撥ね飛ばされた破砕対象物90をさらに反撥板14に衝突させるようにして、こうした一又は複数回の衝突で破砕対象物90を破砕し、所望の大きさの破砕片とする。
破砕後、破砕された破砕片はケーシング11下部に落下し、ケーシング11の排出口から外部に排出される。
In the crushing device 10, like the known impact crusher, the crushing object 90 thrown into the casing 11 from the inlet 15 is made to collide with the striker 13 that rotates integrally with the rotor 12, or hit the striker 13 to repel it. The crushing object 90 is further collided with the repulsion plate 14, and the crushing object 90 is crushed by such one or more collisions to obtain a crushing piece having a desired size.
After crushing, the crushed pieces fall to the lower part of the casing 11 and are discharged from the outlet of the casing 11 to the outside.

以上のように、破砕対象物90の移送から破砕装置10による破砕対象物90の破砕までの各工程が連続して実行され、通常は破砕装置10が作動して破砕対象物90の破砕を行うのに合わせて、各コンベヤ20、30による破砕対象物90の移送がなされる仕組みである。   As described above, each process from the transfer of the crushing object 90 to the crushing of the crushing object 90 by the crushing apparatus 10 is continuously performed, and the crushing apparatus 10 is normally operated to crush the crushing object 90. In accordance with this, the crushing object 90 is transferred by the conveyors 20 and 30.

第一のコンベヤ20及び第二のコンベヤ30による破砕対象物90の移送が行われる場合、異物検出部50からは、第一のコンベヤ20で破砕対象物90の移送が実行される間、異物検出結果を含まない制御用情報が制御部40に送出される。制御部40はこの異物検出結果を含まない制御用情報に基づいて、第一のコンベヤ20が移送実行状態にあることを取得、認識できる。また、第一のコンベヤ20の移送に係る作動は破砕装置10の作動と対応するものであることから、制御部40は同時に破砕装置10についても第一コンベヤ同様に作動状態にあることを認識できる。   When the crushing object 90 is transferred by the first conveyor 20 and the second conveyor 30, the foreign object detection unit 50 detects the foreign object while the crushing object 90 is transferred by the first conveyor 20. Control information that does not include the result is sent to the control unit 40. The control unit 40 can acquire and recognize that the first conveyor 20 is in the transfer execution state based on the control information that does not include the foreign object detection result. Moreover, since the operation | movement which concerns on transfer of the 1st conveyor 20 respond | corresponds with the action | operation of the crushing apparatus 10, the control part 40 can recognize simultaneously that it is the operation | movement state also about the crushing apparatus 10 similarly to a 1st conveyor. .

そして、制御部40は、破砕装置作動中の所定タイミング、具体的には、破砕装置の作動と同義と見なす第一のコンベヤ20での移送実行状態が続く中、この移送実行状態であらかじめ設定された所定時間が経過するごとに、その経過時点で第二のコンベヤ30におけるアクチュエータ31を作動させ、破砕装置10に対し第二のコンベヤ30の一端部を横に移動させて、第二のコンベヤ30の一端部から送り出される破砕対象物の破砕装置投入口15における到達位置をそれまでとは異なる位置に変化させる。   The control unit 40 is preset in this transfer execution state while the transfer execution state continues at a predetermined timing during operation of the crushing device, specifically, the first conveyor 20 regarded as synonymous with the operation of the crushing device. When the predetermined time elapses, the actuator 31 in the second conveyor 30 is actuated at that time, and one end of the second conveyor 30 is moved laterally with respect to the crushing device 10, so that the second conveyor 30 The arrival position of the crushing object fed out from one end of the crushing device at the crushing device inlet 15 is changed to a position different from the previous position.

この後も、制御部40は、破砕装置10における破砕と第一のコンベヤ20での移送が行われる間、あらかじめ設定された前記所定時間が経過するごとに、第二のコンベヤ30の一端部の位置を変化させていき、破砕対象物90の破砕装置投入口15における到達位置を所定時間ごとに移動させる。その結果、破砕装置10の破砕に係る作動が続く間、破砕対象物90と破砕装置内の打撃子や反撥板との衝突位置を所定時間ごとにずらすことができ、衝突位置を集中させず均等化して、打撃子や反撥板の摩耗も偏りなく均等に進行させられ、消耗部品である打撃子や反撥板の摩耗限界に達するまでの時間をできるだけ長くして、これらの消耗部品をより効率よく使用可能となる。   After this, the control unit 40 is connected to the end of the second conveyor 30 every time the predetermined time elapses while the crushing in the crushing apparatus 10 and the transfer on the first conveyor 20 are performed. The position is changed, and the arrival position of the crushing object 90 at the crushing device inlet 15 is moved every predetermined time. As a result, while the operation related to crushing of the crushing device 10 continues, the collision position between the crushing object 90 and the striker or the repulsion plate in the crushing device can be shifted every predetermined time, and the collision position is not concentrated and evenly distributed. The wearer and repellent plate wear is evenly distributed evenly, and the time required to reach the wear limit of the consumable component striker and repellent plate is made as long as possible to make these consumable components more efficient. Can be used.

一方、破砕装置10や各コンベヤ20、30が作動している中、第一のコンベヤ20で移送される破砕対象物90中に異物91が混入している場合、異物検出部50が破砕対象物90に混じった異物91を検出し、この異物検出結果を含む制御用情報を制御部40に送出する。   On the other hand, when the crushing apparatus 10 and the conveyors 20 and 30 are operating, and the foreign object 91 is mixed in the crushing object 90 transferred by the first conveyor 20, the foreign object detection unit 50 detects the crushing object. The foreign matter 91 mixed in 90 is detected, and control information including the foreign matter detection result is sent to the control unit 40.

制御部40は、異物検出部50からの異物検出結果を含む制御用情報を受け取ると、第二のコンベヤ30の移送速度を調整制御し、移送速度を当初より大きくする。加えて、制御部40は、第一のコンベヤ20で移送される異物91が第一のコンベヤ20端部から第二のコンベヤ30に載り移る時、より詳細には、第一のコンベヤ20における異物検出位置と第一コンベヤ20の既知の移送速度に基づいて制御部40で算出された、異物検出時点から異物が第一のコンベヤ端部を出るまでの予測経過時間が過ぎた時に、第二のコンベヤ30を順方向移送状態から、第二のコンベヤ30の移送方向を破砕装置投入口15から離れる向きとする逆方向移送状態に切替える。ただし、第二のコンベヤ30における移送速度の大きさは、移送方向が逆になっても移送速度の大きさの目標値は前と同じとして速度調整されることで、制御部40による前記調整後の当初より大きくされた移送速度と同じ大きさとなる。   When the control unit 40 receives the control information including the foreign object detection result from the foreign object detection unit 50, the control unit 40 adjusts and controls the transfer speed of the second conveyor 30 to increase the transfer speed from the beginning. In addition, when the foreign material 91 transported by the first conveyor 20 is transferred from the end of the first conveyor 20 to the second conveyor 30, more specifically, the control unit 40 detects the foreign material in the first conveyor 20. When the estimated elapsed time from the detection of the foreign matter until the foreign matter exits the first conveyor end calculated by the control unit 40 based on the detection position and the known transfer speed of the first conveyor 20, the second The conveyor 30 is switched from the forward transfer state to the reverse transfer state in which the transfer direction of the second conveyor 30 is away from the crushing device inlet 15. However, the magnitude of the transfer speed in the second conveyor 30 is adjusted as the target value of the magnitude of the transfer speed is the same as before even after the transfer direction is reversed. It becomes the same size as the transfer speed which was increased from the beginning.

逆方向移送状態に切替えられた第二のコンベヤ30は、コンベヤ上の破砕対象物90及び異物91を破砕装置投入口15から離れる向きに移送する。この逆方向移送状態における移送速度は、制御部40による前記調整後の当初より大きくされた移送速度と大きさが同じであることから、第一のコンベヤ20から第二のコンベヤ30に載り移った破砕対象物の、第二のコンベヤ30上における載置密度を通常より小さくすることができる。   The second conveyor 30 switched to the reverse transfer state transfers the crushing object 90 and the foreign matter 91 on the conveyor in a direction away from the crushing device inlet 15. Since the transfer speed in the reverse transfer state is the same as the transfer speed increased from the original after the adjustment by the control unit 40, the transfer speed is transferred from the first conveyor 20 to the second conveyor 30. The placement density of the object to be crushed on the second conveyor 30 can be made smaller than usual.

そして、第二のコンベヤ30は、移送を進めて、コンベヤ上で最も破砕装置投入口15から離れた位置にある異物をコンベヤ他端部から排出路32に向け落下させて送り出す。そして、これと同時に、制御部40は、第二のコンベヤを逆方向移送状態から順方向移送状態に切替える。ただし、この時も、第二のコンベヤ30における移送速度の大きさは、移送方向変化に関わりなく、制御部40による前記調整後の当初より大きくされた移送速度の大きさと同じである。この後、制御部40は、逆方向移送状態から順方向移送状態への切替えから所定時間経過し、第二のコンベヤ30上における前記異物のあった箇所が、第二のコンベヤ30における第一のコンベヤ20からの破砕対象物等が載り移る位置に達する時に、移送速度を調整制御し、当初の移送速度に戻すこととなる。   Then, the second conveyor 30 advances the transfer, and drops and sends out the foreign matter that is farthest from the crushing device inlet 15 on the conveyor toward the discharge path 32 from the other end of the conveyor. At the same time, the control unit 40 switches the second conveyor from the reverse transfer state to the forward transfer state. However, also at this time, the magnitude of the transfer speed in the second conveyor 30 is the same as the magnitude of the transfer speed increased from the beginning after the adjustment by the control unit 40 regardless of the change in the transfer direction. Thereafter, the control unit 40 has passed a predetermined time from the switching from the reverse transfer state to the forward transfer state, and the location where the foreign matter is present on the second conveyor 30 is the first in the second conveyor 30. When reaching the position where the object to be crushed from the conveyor 20 is transferred, the transfer speed is adjusted and controlled to return to the original transfer speed.

異物を異物検出部50で検出してからしばらくの間、第二のコンベヤ30の移送速度の大きさを当初より大きくすることで、異物が検出されてから第一のコンベヤ20から第二のコンベヤ30に異物が載り移るまでに、第一のコンベヤ20から第二のコンベヤ30に載り移った破砕対象物の、第二のコンベヤ30上における載置密度を小さくすると共に、破砕対象物の第二のコンベヤ30上から破砕装置の投入口15に進む割合を多くして、異物が第一のコンベヤ20から第二のコンベヤ30に載り移って第二のコンベヤ30が逆方向移送状態に切り替わった時点で、第二のコンベヤ30上の破砕対象物の量を少なくすることができ、第二のコンベヤ30をよりスムーズに動かして異物を無理なく移送して排出できる。   For a while after the foreign matter is detected by the foreign matter detection unit 50, the transfer speed of the second conveyor 30 is increased from the beginning so that the foreign matter is detected and then the first conveyor 20 to the second conveyor. The crushing object transferred from the first conveyor 20 to the second conveyor 30 by the time the foreign matter is transferred to the second conveyor 30 is reduced in the mounting density on the second conveyor 30 and the crushing object second The rate at which the rate of advancement from the conveyor 30 to the crushing device inlet 15 is increased, and foreign matter is transferred from the first conveyor 20 to the second conveyor 30 and the second conveyor 30 is switched to the reverse transfer state. Thus, the amount of objects to be crushed on the second conveyor 30 can be reduced, and the second conveyor 30 can be moved more smoothly so that foreign matters can be transported and discharged without difficulty.

また、仮に誤って異物と共に破砕対象物が第二のコンベヤ30から落下して排出される場合でも、この排出される破砕対象物の量をできるだけ少なくして、損失を抑えて破砕をより効率よく進められる。さらに、異物が排出されて第二のコンベヤ30が順方向移送状態に切り替わった後、第一のコンベヤ20から第二のコンベヤ30に破砕対象物90が載り移っても、移送速度の大きさを大きくして第二のコンベヤ30上の破砕対象物90を少なくしていた分、第二のコンベヤ30上の破砕対象物90が過剰にならず、第一のコンベヤ20を一時停止させなくても第二のコンベヤ30による破砕対象物90の移送を無理なく継続できる。   Even if the object to be crushed is accidentally dropped from the second conveyor 30 and discharged together with foreign objects, the amount of the object to be crushed is reduced as much as possible, the loss is suppressed, and the crushing object is more efficiently performed. It is advanced. Furthermore, after the foreign matter is discharged and the second conveyor 30 is switched to the forward transfer state, even if the crushing object 90 is transferred from the first conveyor 20 to the second conveyor 30, the transfer speed is increased. Since the crushing object 90 on the second conveyor 30 is reduced by increasing the size, the crushing object 90 on the second conveyor 30 is not excessive, and the first conveyor 20 is not temporarily stopped. The transfer of the object 90 to be crushed by the second conveyor 30 can be continued without difficulty.

順方向移送状態に切り替えられ、移送速度も当初の状態に戻った第二のコンベヤ30により、異物を除去された破砕対象物90は前記同様に破砕装置側に移送され、コンベヤ一端部から落下し、案内部60内のチェーン70のある領域を経て破砕装置の投入口15へ向かうこととなる。   The crushing object 90 from which foreign matter has been removed is transferred to the crushing device side by the second conveyor 30 that has been switched to the forward transfer state and the transfer speed has returned to the original state, and falls from one end of the conveyor in the same manner as described above. Then, it goes to the inlet 15 of the crushing device through a certain region of the chain 70 in the guide portion 60.

このように、本実施形態に係る破砕装置用移送システムにおいては、第一のコンベヤ20で移送される破砕対象物90に混入した金属製の異物91を異物検出部50で検出すると、異物91が第一のコンベヤ20から第二のコンベヤ30に載り移った時点で、制御部40が第二のコンベヤ30を順方向移送状態から逆方向移送状態に切替え、第二のコンベヤ30上の異物91を破砕装置10の投入口15とは遠ざけて排出可能とすることから、異物91を第二のコンベヤ30から破砕装置10の投入口15に投入せずに済み、破砕装置10内部の各機構と硬質な異物91との接触、衝突に基づく機構の異常な摩耗や破損を防止でき、破砕装置10における摩耗する消耗部品の耐久性を高められ、消耗部品の交換頻度を減らして経済性を向上させられる。   Thus, in the crushing device transfer system according to the present embodiment, when the metal foreign matter 91 mixed in the crushing object 90 transferred by the first conveyor 20 is detected by the foreign matter detection unit 50, the foreign matter 91 is detected. When the first conveyor 20 is transferred to the second conveyor 30, the controller 40 switches the second conveyor 30 from the forward transfer state to the reverse transfer state, and the foreign matter 91 on the second conveyor 30 is removed. Since it can be discharged away from the charging port 15 of the crushing device 10, it is not necessary to put the foreign material 91 into the charging port 15 of the crushing device 10 from the second conveyor 30. Can prevent abnormal wear and breakage of the mechanism based on contact with and collision with a foreign object 91, increase the durability of the consumable parts to be worn in the crushing apparatus 10, and reduce the replacement frequency of the consumable parts to improve economy. It is.

なお、前記実施形態に係る破砕装置用移送システムにおいては、制御部40で破砕装置10が破砕に係る作動状態にあるか否かを判断するのに、異物検出部50で取得した情報に基づいて第一のコンベヤ20の移送実行状態を判別し、間接的に破砕装置10の作動状態を判断するようにして、制御系統を破砕装置10とは独立させて簡略化する構成としているが、これに限らず、制御部で破砕装置の破砕に係る作動状態を直接監視して、その作動に応じてタイミング設定を行う制御構成とすることもできる。   In the crushing device transfer system according to the embodiment, the control unit 40 determines whether or not the crushing device 10 is in an operation state related to crushing, based on information acquired by the foreign matter detection unit 50. Although the transfer execution state of the first conveyor 20 is discriminated and the operation state of the crushing device 10 is indirectly determined, the control system is simplified and independent from the crushing device 10. Not limited to this, the control unit can directly monitor the operation state related to the crushing of the crushing apparatus, and a control configuration in which the timing is set according to the operation can also be adopted.

また、前記実施形態に係る破砕装置用移送システムにおいては、異物検出部50で異物91を検出すると、制御部40で第二のコンベヤ30の移送状態を調整制御して異物91を排出し、破砕装置10に向かわせない構成としているが、この他、異物検出部で検出された異物が破砕装置に影響を与えないものである場合、必ずしも排出せず、そのまま第二のコンベヤの順方向移送状態を維持して破砕装置に投入する構成とすることもできる。例えば、異物検出部としてビデオカメラ等の撮像手段で破砕対象物他の画像を取得し、画像解析等の検出手法により異物を検出する場合、異物検出と共に異物の破砕装置への影響の有無も判別しやすいことから、異物の破砕装置への影響なしと判断できる場合に、異物排出に係る制御を省略するようにすれば、破砕対象物の破砕装置への送出状態に変化が生じにくくなり、より効率よく破砕を進められる。   Further, in the crushing device transfer system according to the embodiment, when the foreign object 91 is detected by the foreign object detection unit 50, the control unit 40 adjusts and controls the transfer state of the second conveyor 30 to discharge the foreign object 91 and crush it. Although it is set as the structure which does not go to the apparatus 10, in addition to this, when the foreign material detected by the foreign material detection part does not affect the crushing apparatus, it does not necessarily discharge | emit, but the forward transfer state of a 2nd conveyor as it is It can also be set as the structure which inputs and puts into a crushing apparatus. For example, when an image of a crushing object or the like is acquired by an imaging means such as a video camera as a foreign substance detection unit and a foreign object is detected by a detection method such as image analysis, the presence or absence of the influence of the foreign object on the crushing device is also determined If it can be determined that there is no impact on the crushing device for foreign matter, if the control related to the discharge of foreign matter is omitted, the state of sending the crushing object to the crushing device will not easily change, and more Crushing can be carried out efficiently.

また、前記実施形態に係る破砕装置用移送システムにおいては、第二のコンベヤ30における移送状態を切り替える機構で異物91の排出を図ると共に、第二のコンベヤ30の一端部を横に移動させる機構で破砕対象物90の破砕装置投入口15における到達位置を移動させ、破砕対象物90と破砕装置10内各機構との衝突位置を集中させず摩耗の均等化を図る構成としているが、この他、前記前者の異物の排出を図るための機構のみとして、後者の摩耗の均等化を図るための機構を省略した移送システムとしたり、前記前者の異物の排出を図るための機構を省略して、後者の摩耗の均等化を図るための機構のみ採用した移送システムとする構成としてもかまわない。   In the crushing device transfer system according to the embodiment, the mechanism for switching the transfer state in the second conveyor 30 discharges the foreign matter 91 and moves the one end of the second conveyor 30 sideways. Although the arrival position in the crushing device inlet 15 of the crushing object 90 is moved and the collision position between the crushing object 90 and each mechanism in the crushing device 10 is not concentrated, the wear is equalized. Only the mechanism for discharging the former foreign matter is a transfer system that omits the mechanism for equalizing the latter wear, or the mechanism for discharging the former foreign matter is omitted, and the latter It may be configured as a transfer system that employs only a mechanism for equalizing the wear.

(本発明の第2の実施形態)
前記第1の実施形態に係る破砕装置用移送システムにおいては、破砕装置10と第一のコンベヤ20が作動する間、所定時間が経過するごとに、制御部40による制御で第二のコンベヤ30の一端部の位置を変えて、破砕装置10における破砕対象物の到達位置をずらし、破砕装置内の打撃子や反撥板等における摩耗の均等化を図る構成としているが、この他、第2の実施形態として、第二のコンベヤ30の一端部を横方向に移動させる構成に代えて、又は、第二のコンベヤ30の一端部を横方向に移動させる構成に追加して、図11及び図12に示すように、制御部40による制御で第二のコンベヤ30の移送速度を変えて、第二のコンベヤ30から出る破砕対象物90の破砕装置投入口15における到達位置を第二のコンベヤ30の移送方向について変化させ、前記実施形態同様に破砕装置内各部の摩耗を均等にする構成とすることもできる。
(Second embodiment of the present invention)
In the crushing device transfer system according to the first embodiment, the control unit 40 controls the second conveyor 30 every time a predetermined time elapses while the crushing device 10 and the first conveyor 20 operate. The position of the one end is changed to shift the arrival position of the object to be crushed in the crushing apparatus 10 so as to equalize the wear on the striker, repulsion plate, etc. in the crushing apparatus. As a form, it replaces with the structure which moves the one end part of the 2nd conveyor 30 to a horizontal direction, or is added to the structure which moves the one end part of the 2nd conveyor 30 to a horizontal direction, FIG.11 and FIG.12. As shown, the transfer speed of the second conveyor 30 is changed under the control of the control unit 40, and the arrival position of the crushing object 90 coming out of the second conveyor 30 at the crushing device inlet 15 is transferred to the second conveyor 30. Changing the direction, it may also be configured to equalize the wear of the embodiment similarly crushing device units.

この場合、制御部40は、破砕装置10の作動中の所定タイミングで、第二のコンベヤ30の順方向移送状態における移送速度を増減変化させて、第二のコンベヤ30の一端部から送り出される破砕対象物90の破砕装置投入口15における到達位置をそれ以前の位置から変化させるよう制御を行う。詳細には、破砕装置10が作動してあらかじめ設定された所定時間が経過するごとに、この経過時点を前記所定タイミングとして、第二のコンベヤ30の移送速度を順次切り替えるように変化させる。   In this case, the control unit 40 changes the transfer speed in the forward transfer state of the second conveyor 30 at a predetermined timing during the operation of the crushing device 10, and crushes sent from one end of the second conveyor 30. Control is performed so as to change the arrival position of the object 90 at the crushing device inlet 15 from the previous position. Specifically, every time a predetermined time set in advance after the crushing apparatus 10 is operated, the transfer speed of the second conveyor 30 is changed in order, with the elapsed time as the predetermined timing.

制御部40で、第二のコンベヤ30の移送速度を変化させるタイミングを規定する前記所定時間は、破砕装置10の打撃子や反撥板等の消耗部品である程度の摩耗が見込める時間経過に対応するようにあらかじめ設定される。この他、破砕装置の各消耗部品の摩耗度合いを直接センサ等で検出して、所定の摩耗量に達したら、そのタイミングで第二のコンベヤ30の移送速度を変化させるようにしてもかまわない。   The predetermined time that defines the timing at which the transfer speed of the second conveyor 30 is changed by the control unit 40 corresponds to the passage of time in which a certain amount of wear can be expected from consumable parts such as a striker and a repellent plate of the crushing apparatus 10. Is preset. In addition, the degree of wear of each consumable part of the crushing device may be directly detected by a sensor or the like, and when the predetermined wear amount is reached, the transfer speed of the second conveyor 30 may be changed at that timing.

制御部40が、破砕装置10における破砕と第一のコンベヤ20での移送が行われる間、あらかじめ設定された前記所定時間が経過するごとに、第二のコンベヤ30の移送速度を変化させていき、破砕対象物90の破砕装置投入口15における到達位置を所定時間ごとに移動させることで、破砕装置10の破砕に係る作動が続く間、破砕対象物90と破砕装置内の打撃子や反撥板との衝突位置を所定時間ごとにずらすことができる。これにより、破砕装置各部における衝突位置の集中がなく、打撃子や反撥板の摩耗も偏りなく均等に進行させられ、消耗部品である打撃子や反撥板の摩耗限界に達するまでの時間をできるだけ長くして、これらの消耗部品をより効率よく使用可能となる。   While the crushing device 10 performs crushing and transfer on the first conveyor 20, the control unit 40 changes the transfer speed of the second conveyor 30 each time the preset predetermined time elapses. By moving the arrival position of the crushing object 90 at the crushing device inlet 15 every predetermined time, while the operation related to crushing of the crushing device 10 continues, the crushing object 90 and the striker or repulsion plate in the crushing device are continued. Can be shifted at predetermined time intervals. As a result, there is no concentration of the collision position in each part of the crushing device, the wear of the striker and the repellent plate is evenly progressed, and the time until the wear limit of the striker and the repellent plate as consumable parts is reached is as long as possible. Thus, these consumable parts can be used more efficiently.

(本発明の第3の実施形態)
前記第1及び第2の各実施形態に係る破砕装置用移送システムにおいては、制御部40による制御で、第二のコンベヤ30の一端部の位置や移送速度を変えて、破砕装置10における破砕対象物の到達位置を変化させ、破砕装置内の打撃子や反撥板等における摩耗の均等化を図る構成としているが、これに限らず、第3の実施形態として、図13ないし図16に示すように、制御部40の制御に基づいて、破砕装置10上側の案内部60内に設けられる吊下体としての複数のチェーン71、72、73、74の吊り下げ長さを、横方向で長さの差異を与えつつ増減調整して、破砕対象物とチェーン71、72、73、74との接触状態を変え、チェーン71、72、73、74の位置を通過する破砕対象物90の破砕装置投入口15における到達位置を変化させる構成とすることもできる。
(Third embodiment of the present invention)
In the crushing device transport system according to each of the first and second embodiments, the position of the one end portion of the second conveyor 30 and the transfer speed are changed by the control of the control unit 40, and the crushing target in the crushing device 10 is obtained. The arrival position of the object is changed to equalize the wear on the striker, the repulsion plate, etc. in the crushing device. However, the present invention is not limited to this, and the third embodiment is shown in FIGS. Further, based on the control of the control unit 40, the suspension lengths of the plurality of chains 71, 72, 73, 74 as suspension bodies provided in the guide unit 60 on the upper side of the crushing apparatus 10 are set in the lateral direction. Increase / decrease adjustment while giving a difference to change the contact state between the crushing object and the chains 71, 72, 73, 74 and pass the crushing object 90 through the position of the chains 71, 72, 73, 74. In 15 It may be configured to vary the reach position.

この場合、案内部60内で一端部をアクチュエータ80に連結されて吊り下げ状態で配設される複数のチェーン71、72、73、74は、横方向に複数の組に分けられており、この複数の組ごとにそれぞれアクチュエータ80で吊り下げ長さを調整可能とされる。そして横方向の一側にある複数のチェーン71、72の組と、横方向の他側にある別の複数のチェーン73、74の組とで、アクチュエータ80の作動状態を異ならせるようにして、チェーン71、72、73、74の吊り下げ長さが組ごとに相違する状態とされる。そして、これらチェーン71、72、73、74に対し、制御部40が、破砕装置10の作動中又は作動の合間の所定タイミングで、アクチュエータ80を作動させて前記一側のチェーン71、72と他側のチェーン73、74との吊り下げ長さの関係を入れ替えるように変化させることとなる。これにより、チェーン71、72、73、74と破砕対象物90との接触状態が前記一側のチェーン71、72と他側のチェーン73、74とで変わり、第二のコンベヤ30の一端部から送り出される破砕対象物の破砕装置投入口15における到達位置をそれ以前の位置から変化させられる仕組みである。   In this case, a plurality of chains 71, 72, 73, 74 arranged in a suspended state with one end connected to the actuator 80 in the guide portion 60 are divided into a plurality of sets in the lateral direction. The suspension length can be adjusted by the actuator 80 for each of a plurality of groups. The operating state of the actuator 80 is made different between a set of a plurality of chains 71 and 72 on one side in the horizontal direction and a set of a plurality of chains 73 and 74 on the other side in the horizontal direction, The hanging lengths of the chains 71, 72, 73, and 74 are different for each group. And with respect to these chains 71, 72, 73, 74, the control unit 40 operates the actuator 80 at a predetermined timing during the operation of the crushing apparatus 10 or between operations, and the other chains 71, 72 on the one side and the like. The relationship of the hanging length with the side chains 73 and 74 is changed so as to be exchanged. Thereby, the contact state of the chains 71, 72, 73, 74 and the crushing object 90 is changed between the one chain 71, 72 and the other chain 73, 74, and from one end of the second conveyor 30. This is a mechanism in which the arrival position of the object to be crushed at the crushing device inlet 15 can be changed from the previous position.

具体的には、破砕装置10が作動してあらかじめ設定された所定時間が経過するごとに、この経過時点を前記所定タイミングとして、制御部40は各アクチュエータ80を作動させて、前記一側のチェーン71、72の組と他側のチェーン73、74の組との吊り下げ長さの関係をそれ以前の状態から入れ替えるように吊り下げ長さを変化させる。例えば、一側のチェーン71、72に対し他側のチェーン73、74が吊り下げ長さをより長くされる状態(図13、図14参照)と、一側のチェーン70が他側のチェーン73、74に対し吊り下げ長さをより長くされる状態(図15、図16参照)とが、所定時間が経過するごとに入れ替わるよう、各アクチュエータ80の作動が制御される。   Specifically, every time a predetermined time set in advance after the crushing device 10 is operated, the control unit 40 operates each actuator 80 with the elapsed time as the predetermined timing, and the one side chain The suspension length is changed so that the relationship of the suspension length between the pair of 71 and 72 and the pair of chains 73 and 74 on the other side is changed from the previous state. For example, the chain 73 and 74 on the other side is hung longer than the chains 71 and 72 on the one side (see FIGS. 13 and 14), and the chain 70 on the one side is the chain 73 on the other side. 74, the operation of each actuator 80 is controlled so that the state in which the suspending length is made longer (see FIGS. 15 and 16) is switched every time a predetermined time elapses.

制御部40で、各アクチュエータ80を作動させてチェーン71、72、73、74の吊り下げ長さを変化させるタイミングを規定する前記所定時間は、破砕装置10の打撃子や反撥板等の消耗部品である程度の摩耗が見込める時間経過に対応するようにあらかじめ設定される。この他、破砕装置の各消耗部品の摩耗度合いを直接センサ等で検出して、所定の摩耗量に達したら、そのタイミングでアクチュエータ80を作動させ、チェーン71、72、73、74の吊り下げ長さを変化させるようにしてもかまわない。   The control unit 40 operates the actuators 80 to define the timing for changing the suspension length of the chains 71, 72, 73, 74. The predetermined time is a consumable component such as a striker or a repellent plate of the crushing device 10. Is set in advance so as to correspond to the passage of time in which a certain amount of wear can be expected. In addition, the degree of wear of each consumable part of the crushing device is directly detected by a sensor or the like, and when a predetermined amount of wear is reached, the actuator 80 is operated at that timing to suspend the chain 71, 72, 73, 74. It does not matter if you change the height.

制御部40が、破砕装置10における破砕と第一のコンベヤ20での移送が行われる間、あらかじめ設定された前記所定時間が経過するごとに、横方向の一側と他側におけるチェーン71、72、73、74の吊り下げ長さの関係を入れ替えるように吊り下げ長さを調整して、第二のコンベヤ30を出た破砕対象物90とチェーン70との接触状態を変化させることで、破砕対象物90の破砕装置投入口15における到達位置を所定時間ごとにそれまでとは異なる位置に調整できる。こうして破砕装置10における破砕対象物の進行状態を変えて、破砕装置10の破砕に係る作動が続く間、破砕対象物90と破砕装置内の打撃子や反撥板との衝突位置を所定時間ごとにずらすことができる。これにより、破砕装置各部における衝突位置の集中がなくなり、打撃子や反撥板の摩耗を偏りなく均等に進行させられ、消耗部品である打撃子や反撥板の摩耗限界に達するまでの時間をできるだけ長くして、これらの消耗部品をより効率よく使用でき、交換頻度を減らせる。   While the control unit 40 performs crushing in the crushing device 10 and transfer on the first conveyor 20, the chains 71 and 72 on one side and the other side in the lateral direction each time the predetermined time set in advance elapses. , 73, 74 by changing the contact length between the crushing object 90 exiting the second conveyor 30 and the chain 70 by adjusting the suspension length so that the relationship between the suspension lengths is changed. The arrival position of the object 90 at the crushing device inlet 15 can be adjusted to a position different from that at every predetermined time. Thus, while the operation related to crushing of the crushing apparatus 10 continues by changing the state of progress of the crushing object in the crushing apparatus 10, the collision position between the crushing object 90 and the striker or the repulsion plate in the crushing apparatus is changed every predetermined time. Can be shifted. This eliminates the concentration of the collision position at each part of the crushing device, allows the wearer and repellent plate to wear evenly and evenly, and maximizes the time required to reach the wear limit of the striker and rebound plate, which are consumable parts. Thus, these consumable parts can be used more efficiently, and the replacement frequency can be reduced.

なお、前記各実施形態において、案内部60で吊り下げ状態として配設される吊下体は、チェーンとされているが、これに限られるものではなく、吊り下げ状態で案内部60に配設可能で、且つ吊り下げ長さを調整できるものであれば、チェーン以外の、複数部品を多数線状に連結して変形性を付与したものでもよく、また、変形のない連続した棒状のものとしてもかまわない。   In each of the above embodiments, the suspended body disposed in the suspended state in the guide portion 60 is a chain, but is not limited thereto, and can be disposed in the guide portion 60 in the suspended state. In addition, as long as the suspension length can be adjusted, a plurality of parts other than the chain may be connected in a linear shape to impart deformability, or as a continuous rod-like shape without deformation. It doesn't matter.

(本発明の第4の実施形態)
前記第1の実施形態に係る破砕装置用移送システムにおいては、異物検出部50で異物91を検出すると、制御部40で第二のコンベヤ30の移送状態を調整制御して異物91を排出し、破砕装置10に向かわせない構成としているが、この他、第4の実施形態として、図17及び図18に示すように、案内部60における破砕装置10の投入口15側方で且つ第二のコンベヤ30の一端部の下方となる所定箇所で案内部60内に連通する、異物排出用の排出路61を設けると共に、案内部60内における第二のコンベヤ30の一端部と投入口15との間の第一の所定位置から、第二のコンベヤ30の一端部と排出路61との間の第二の所定位置までの角度範囲で少なくとも傾動可能な略板状の切替ダンパー63を設け、さらに制御部40が、切替ダンパー63を傾動させて、切替ダンパー63が前記第二の所定位置にあって破砕対象物90が投入口15のみに進行可能な通常投入状態(図17参照)と、切替ダンパー63が前記第一の所定位置にあって異物91が排出路61のみに進行可能な異物排出状態(図18参照)とを切替える制御を行うようにして、破砕装置10や各コンベヤ20、30が作動している中、異物検出部50が異物を検出して、制御部40が異物検出部50からの異物検出結果を含む制御用情報を受け取ると、前記第1の実施形態における第二のコンベヤ30の異物排出に係る制御に代えて、移送される異物91が第二のコンベヤ30の一端部を出る時に、制御部40が切替ダンパー63を傾動させて通常投入状態から異物排出状態に切替え、異物91を排出路61に進ませて排出する構成とすることもできる。
(Fourth embodiment of the present invention)
In the crushing device transfer system according to the first embodiment, when the foreign matter 91 is detected by the foreign matter detection unit 50, the control unit 40 adjusts and controls the transfer state of the second conveyor 30, and discharges the foreign matter 91. Although it is set as the structure which does not go to the crushing apparatus 10, as shown in FIG.17 and FIG.18, in addition to this, as shown in FIGS. A discharge path 61 for discharging foreign matter is provided at a predetermined position below one end of the conveyor 30 and communicates with the inside of the guide 60, and between the one end of the second conveyor 30 in the guide 60 and the input port 15. A substantially plate-shaped switching damper 63 that can be tilted at least in an angular range from a first predetermined position between the second predetermined position between one end of the second conveyor 30 and the discharge path 61; The control unit 40 The switching damper 63 is tilted so that the switching damper 63 is in the second predetermined position and the crushing object 90 can advance only to the insertion port 15 (see FIG. 17), and the switching damper 63 is the first one. The crushing device 10 and the conveyors 20 and 30 are operated so as to perform control to switch the foreign matter discharge state (see FIG. 18) in which the foreign matter 91 can travel only to the discharge path 61 at one predetermined position. When the foreign matter detection unit 50 detects the foreign matter, and the control unit 40 receives the control information including the foreign matter detection result from the foreign matter detection unit 50, the foreign matter is discharged from the second conveyor 30 in the first embodiment. In place of the control related to the above, when the foreign matter 91 to be transferred exits one end of the second conveyor 30, the control unit 40 tilts the switching damper 63 to switch from the normal input state to the foreign matter discharge state, May be configured to discharge is advanced to Detchi 61.

この場合、破砕装置10に影響を与えるような異物が検出されず、第二のコンベヤ30の一端部から破砕対象物90が出てくる通常時には、切替ダンパー63は通常投入状態にあり、異物が検出されてその異物が案内部60に達した時のみ、切替ダンパー63が異物排出状態に切替えられる。そして、異物91が案内部60を出て排出路61に入り、投入口15側に向かうおそれがなくなった時に、制御部40は切替ダンパー63を傾動させて、異物排出状態から通常投入状態に切替えることとなる。   In this case, no foreign matter that would affect the crushing device 10 is detected, and the switching damper 63 is in a normal input state at the normal time when the crushing object 90 comes out from one end of the second conveyor 30, and the foreign matter is Only when the foreign matter reaches the guide unit 60 after being detected, the switching damper 63 is switched to the foreign matter discharge state. When the foreign matter 91 exits the guide portion 60 and enters the discharge path 61 and no longer moves toward the insertion port 15, the control unit 40 tilts the switching damper 63 to switch from the foreign matter discharge state to the normal input state. It will be.

こうして、移送される破砕対象物90に混入した異物91を異物検出部50で検出すると、異物91が第二のコンベヤ30の一端部を出た時点で制御部40が切替ダンパー63を通常投入状態から異物排出状態に切替え、案内部60内で落下する異物91を破砕装置10の投入口15ではなく排出路61に向かわせて排出可能とすることで、異物91を破砕装置10の投入口15に投入せずに済み、前記第1の実施形態同様、破砕装置10内部の打撃子や反撥板等の各機構と硬質な異物91との接触、衝突に基づく機構の異常な摩耗や破損を防止でき、破砕装置10における摩耗する消耗部品の耐久性を高められ、消耗部品の交換頻度を減らして経済性を向上させられる。   Thus, when the foreign matter 91 mixed in the crushing object 90 to be transferred is detected by the foreign matter detection unit 50, the control unit 40 normally puts the switching damper 63 when the foreign matter 91 leaves one end of the second conveyor 30. The foreign material 91 is switched to the foreign material discharge state, and the foreign material 91 falling in the guide portion 60 can be discharged toward the discharge path 61 instead of the input port 15 of the crushing device 10. As in the first embodiment, contact between the crushing device 10 and other mechanisms such as the striker and the repulsion plate and the hard foreign matter 91 prevents abnormal wear and damage to the mechanism based on the collision. It is possible to improve the durability of the consumable parts to be worn in the crushing apparatus 10, and to reduce the replacement frequency of the consumable parts, thereby improving the economy.

なお、このように破砕装置10上方の案内部60に達した異物91を排出するための機構を採用する一方、前記各実施形態に示すような破砕対象物の破砕装置投入口における到達位置を変化させて破砕装置内各部における摩耗の均等化を図るための機構については省略するシステム構成とする場合には、破砕対象物を破砕装置に向けて移送するコンベヤを一つのみ用いるようにすることもでき、コンベヤ使用数を必要最小限とすることでシステムを簡略化でき、コストを抑えられると共に信頼性も高められる。   In addition, while adopting a mechanism for discharging the foreign matter 91 that has reached the guide unit 60 above the crushing device 10 in this way, the arrival position of the crushing object at the crushing device inlet as shown in each of the above embodiments is changed. In the case of a system configuration that omits a mechanism for equalizing wear in each part in the crushing device, it is also possible to use only one conveyor for transferring the object to be crushed toward the crushing device. In addition, the system can be simplified by minimizing the number of conveyors used, thereby reducing costs and increasing reliability.

また、前記各実施形態に係る破砕装置用移送システムにおいて、破砕対象物の移送に第一のコンベヤと第二コンベヤの二つを配設する構成としているが、これに限られるものではなく、移送開始位置から破砕装置までの距離に応じて、コンベヤを三つ以上の複数台並べて順次破砕対象物を破砕装置に向けて移送する構成とすることもできる。この場合、コンベヤのうち最も破砕装置寄りのコンベヤを、前記第二のコンベヤと同様の構成とした上で制御部での前記同様の制御に基づき作動させることで、前記実施形態同様に異物の排出や破砕装置内各部の摩耗の均等化を実現可能とすることができる。   Moreover, in the transfer system for crushing apparatuses according to each of the above embodiments, the first conveyor and the second conveyor are arranged for transferring the object to be crushed. However, the present invention is not limited to this. Depending on the distance from the start position to the crushing device, it is possible to arrange three or more conveyors and sequentially transfer the objects to be crushed toward the crushing device. In this case, the conveyor closest to the crushing device among the conveyors has the same configuration as the second conveyor and is operated based on the same control in the control unit, thereby discharging foreign matter as in the above embodiment. It is possible to realize equalization of wear of each part in the crushing apparatus.

この他、前記第1ないし第4の各実施形態に係る破砕装置用移送システムに関連して、本発明の開示する破砕装置用移送システムのさらなる態様について、以下に示す。
(態様1)

当該第二のコンベヤの前記一端部を横方向に移動させて、破砕装置に対する前記一端部の位置を調整する制御を行う制御部とを備え、
前記制御部が、前記破砕装置の作動中又は作動の合間の所定タイミングで、破砕装置に対し前記第二のコンベヤの一端部を横に移動させて、第二のコンベヤの一端部から送り出される破砕対象物の破砕装置投入口における到達位置を変えることを
