Description

本発明は、複数種の鉄鋼製品の試料から複数種の自動機械加工機を用いて複数種の機械試験片を加工製造する機械試験片の加工製造システム及び方法に関する。   The present invention relates to a mechanical test piece processing and manufacturing system and method for processing and manufacturing a plurality of types of mechanical test pieces from a plurality of types of steel product samples using a plurality of types of automatic machining machines.

一般に、鋼材製品を製造、販売する場合、製造した鋼材から試料を採取し、これを規格により形状や寸法精度が厳密に定められた複数種の機械試験片に加工製造した上で、これら機械試験片に対して実際に引張破壊試験や衝撃破壊試験等の機械試験を実施し、その結果をもって製品の品質管理や品質保証を行うことがなされている。   In general, when manufacturing and selling steel products, samples are collected from the manufactured steel materials, processed into multiple types of mechanical test pieces whose shape and dimensional accuracy are strictly defined by the standards, and these mechanical tests are performed. A mechanical test such as a tensile fracture test and an impact fracture test is actually performed on the piece, and based on the result, quality control and quality assurance of the product are performed.

試料から機械試験片への加工は、粗切断、二次切断、減厚、研削、面取り、研磨というように多種多様な工程があり、複数種の機械加工機を経て加工が行われる。   Processing from a sample to a mechanical test piece includes various processes such as rough cutting, secondary cutting, thickness reduction, grinding, chamfering, and polishing, and processing is performed through a plurality of types of machining machines.

一般的に、自動旋盤、自動フライス盤等の自動機械加工機は、試料の精密位置決め固定治具を装備しており、作業者は、同治具に試料を嵌め合い、押し付け、クランプ、ネジ止め等するセット作業と、加工寸法等の加工情報を自動機械加工機に付与する作業とを行う。その後、自動機械加工機単独による自動加工が行われ、加工終了後は、作業者が同治具から加工品を取り外す作業を行う、という機能分担のものが多い。   In general, automatic machining machines such as automatic lathes and automatic milling machines are equipped with a precision positioning fixture for specimens, and the operator fits, presses, clamps, and screws the specimens in the jig. A setting operation and an operation for giving processing information such as processing dimensions to the automatic machining machine are performed. Thereafter, automatic machining is performed by an automatic machining machine alone, and after the completion of machining, there are many functions sharing that the operator performs a work of removing the workpiece from the jig.

しかしながら、一般に自動機械加工機への試料の位置決め固定治具は自動機械加工機の種類によって異なっており、精密かつ正確なセットが要求されるため、機械化・自動化が難しい作業である。特に、供給される試料の形状や寸法精度が安定しない場合には、作業者による高い技能が要求される。   However, in general, the specimen positioning / fixing jig for the automatic machining machine differs depending on the type of the automatic machining machine, and a precise and accurate set is required. Therefore, it is difficult to perform mechanization and automation. In particular, when the shape and dimensional accuracy of the supplied sample are not stable, a high level of skill by the operator is required.

この場合、作業者が試料の運搬、自動機械加工機へのセット、取り外し・取り出しを行うため、複数種の自動機械加工機を複数台扱う機械試験片加工施設においては、作業者が多量の試料を運搬・移動する回数や距離が大きくなり、効率が非常に悪い。   In this case, the operator transports the sample, sets it in the automatic machining machine, removes it, and removes it. In a mechanical test piece processing facility that handles multiple types of automatic machining machines, the operator has a large amount of samples. The number and distance of transporting / moving is increased, and the efficiency is very poor.

特許文献１では、パレットの待機時間を削減して自動機械加工機の稼働率を向上することが記載されているが、試料や治具の搬送、ハンドリングについては言及されていない。   In Patent Document 1, it is described that the waiting time of the pallet is reduced and the operating rate of the automatic machining machine is improved, but there is no mention of conveyance and handling of the sample and the jig.

また、特許文献２では、シャルピー試験片製造用マシニングセンタの自動化について記載されているが、シャルピー試験片に限定されており、また、試料や治具の搬送、ハンドリングについては言及されていない。   Patent Document 2 describes the automation of a machining center for manufacturing a Charpy test piece, but is limited to the Charpy test piece, and does not mention transport and handling of samples and jigs.

また、特許文献３では、搬送台車、貯留部等から構成される機械加工施設について記載されているが、治具への試料のセットが機械による完全自動で可能であるという前提であり、試料の製作精度が悪い、等の作業者介入が必要な場合には適用できない。   Patent Document 3 describes a machining facility composed of a transport carriage, a storage unit, and the like. However, it is a premise that a sample can be set on a jig by a fully automatic machine. It cannot be applied when operator intervention is required, such as poor production accuracy.

本発明は上記のような点に鑑みてなされたものであり、複数種の試料から、複数種で複数台の自動機械加工機を扱い、複数種の機械試験片を加工製造する場合において、試料の大きさや形状が多種多様であったり、試料の自動機械加工機へのセットに作業者の技能が必要であったりする場合に、ベルトコンベアや無人搬送台車等の自動搬送装置の導入、完全自動加工と手加工のエリア分割による作業者移動や試料運搬範囲の最小化等を図り、効率化・合理化を進めることを目的とする。   The present invention has been made in view of the above points. In the case of handling a plurality of types of automatic machining machines from a plurality of types of samples and processing and manufacturing a plurality of types of mechanical test pieces, the sample is provided. Automatic conveyors such as belt conveyors and unmanned conveyor carts are fully automatic when there are a wide variety of sizes and shapes, or when the operator's skill is required to set samples on an automated machine The purpose is to improve efficiency and rationalization by minimizing the movement of workers and sample transport range by dividing the area into processing and manual processing.

本発明の機械試験片の加工製造システムは、複数異種の試料を複数異種の自動機械加工機で複数異種の機械試験片へと加工製造するために試料搬送用のパレットを用いて自動的に運搬、搬入、加工、搬出する機械試験片の加工製造システムであって、外形寸法及び重量が数種類に規格化されたパレットと、前記パレット上の試料の位置決め固定治具と、前記パレットを位置決め固定する位置決め固定治具を備えるとともに、前記パレットの位置決め固定及び取り外し機能を有する自動機械加工機と、前記パレットを共通して搬送する自動搬送装置と、前記パレットへの試料の位置決め固定及び取り外しを行う自動加工受け渡し台と、試料を受け付ける１ヶ所の受付部とを備えた点に特徴を有する。

本発明の機械試験片の加工製造方法は、複数異種の試料を複数異種の自動機械加工機等で複数異種の機械試験片へと加工製造するために試料搬送用のパレットを用いて自動的に運搬、搬入、加工、搬出する機械試験片の加工製造方法であって、１ヶ所の受付部で試料を受け付ける手順と、自動加工受け渡し台で外形寸法及び重量が数種類に規格化されたパレット上の試料の位置決め固定治具によって試料をパレットに固定する手順と、前記試料自動搬送装置で前記パレットを自動機械加工機まで搬送し、該パレットに自動機械加工機毎に付属する自動機械加工機上のパレットの位置決め固定治具によって該パレットと自動機械加工機との相互の位置決めを行う手順と、前記自動機械加工機での加工後に前記パレットを前記自動搬送装置に再び載せ、製品受け取り台或いは前記自動加工受け渡し台へと搬送する手順とを有する点に特徴を有する。
また、本発明の機械試験片の加工製造方法の他の特徴とするところは、前記試料搬送用のパレットが具備する記録媒体に、試料のパレットへの固定時、搬送の前後、パレットの自動機械加工機への固定時或いは加工終了時に加工に必要な情報の読み込み又は書き込みを行う点にある。 The machine test piece processing / manufacturing system of the present invention automatically conveys a plurality of different types of samples using a sample transport pallet to process and manufacture a plurality of different types of samples into a plurality of different types of mechanical test pieces. A system for processing, manufacturing, carrying out, and unloading mechanical test pieces, which includes a pallet with standardized external dimensions and weights, a positioning fixture for specimens on the pallet, and positioning and fixing the pallet.

The point is that information necessary for processing is read or written at the time of fixing to the processing machine or at the end of processing.

本発明によれば、複数種の自動機械加工機を複数台扱い、複数種の機械試験片を加工製造する場合において、自動搬送装置を用いた自動搬送と、位置決め固定治具への試料セットの局所集中が可能となり、試料の種類の多さや大きさや形状の多様性に拘わらず、精度を担保しながら自動搬送による作業の効率化・合理化を図ることができる。   According to the present invention, when handling a plurality of types of automatic machining machines and processing and manufacturing a plurality of types of mechanical test pieces, automatic conveyance using an automatic conveyance device and sample setting to a positioning fixture are performed. Local concentration is possible, and the efficiency and rationalization of work by automatic conveyance can be achieved while ensuring accuracy, regardless of the variety of sample types, the size, and the variety of shapes.

以下、図面を参照して、本発明の好適な実施形態について説明する。図１に機械試験片の加工製造システムの全体構成を示す。まず、加工する試料は、手加工工程２を経て、機械試験片や使用する自動機械加工機の種類に依らず１ヶ箇所の受付部１で受け付けられる。続いて、この試料は自動加工受け渡し台３へ運ばれ、パレット８の位置決め固定治具によってセットされる。   Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the overall configuration of a mechanical test piece processing and manufacturing system. First, a sample to be processed is received by one receiving unit 1 through a manual processing step 2 regardless of the type of a mechanical test piece or an automatic machining machine to be used. Subsequently, the sample is carried to the automatic processing delivery table 3 and set by the positioning and fixing jig of the pallet 8.

自動加工受け渡し台３に対して受付部１の反対側には、自動加工受け渡し台３から自動加工エリア５の各自動機械加工機６へと試料の固定されたパレット８を搬送するための自動搬送装置４が設置される。自動搬送装置４は、例えばベルトコンベア又は自動搬送台車とする。パレット８の行き先となる自動機械加工機６の種類は、パレット８に記録された情報により自動搬送装置４が自動的に判別する。自動機械加工機６は、パレット８の受け入れ、自動把持固定、加工に必要な情報の読み込み等の機能を具備する。   On the opposite side of the receiving section 1 with respect to the automatic processing delivery table 3, automatic conveyance for conveying the pallet 8 on which the sample is fixed from the automatic processing delivery table 3 to each automatic machining machine 6 in the automatic machining area 5. A device 4 is installed. The automatic conveyance device 4 is, for example, a belt conveyor or an automatic conveyance carriage. The type of the automatic machining machine 6 that is the destination of the pallet 8 is automatically determined by the automatic transfer device 4 based on the information recorded on the pallet 8. The automatic machine 6 has functions such as receiving a pallet 8, automatically holding and fixing, and reading information necessary for processing.

試料を受けた自動機械加工機６のうち中間加工機６（ｃ）はその分担する加工を行い、自動搬送装置４に返し、加工された試料は再び自動加工受け渡し台３へ返る。また、試料を受けた仕上げ加工機６（ａ）又は６（ｂ）はその分担する加工を行い、自動搬送装置４に返し、加工された試料は製品受け取り台７へ渡る。製品受け取り台７からは複数種で複数個の機械試験片が依頼元へと出荷される。   Among the automatic machining machines 6 that have received the sample, the intermediate processing machine 6 (c) performs the processing that is assigned to it and returns it to the automatic transfer device 4, and the processed sample returns to the automatic machining transfer table 3 again. Also, the finishing machine 6 (a) or 6 (b) that receives the sample performs the processing that is assigned to it, and returns it to the automatic transfer device 4, and the processed sample passes to the product receiving table 7. A plurality of types of mechanical test pieces are shipped from the product receiving stand 7 to the requester.

ここで、図２も参照して、自動機械加工機６及びパレット８について説明する。自動機械加工機６は、一般の自動機械加工機に付設されているような位置決め固定治具の部位が取り外され、これに代替してパレット８の皿部を把持して固定する機能が付加され、自動機械加工機６とパレット８との相対的な位置関係が把持状態にて一意に定まり、かつ、確実に固定される構造に改造されている。例えば、自動機械加工機６とパレット８とが数ヶ所の凸円錐と凹円錐の組合せで嵌合する構造とする。   Here, the automatic machining machine 6 and the pallet 8 will be described with reference to FIG. The automatic machining machine 6 is provided with a function of removing and fixing a positioning and fixing jig portion attached to a general automatic machining machine and holding and fixing the plate portion of the pallet 8 instead. The relative positional relationship between the automatic machining machine 6 and the pallet 8 is uniquely determined in the gripping state, and is remodeled so as to be securely fixed. For example, the automatic machining machine 6 and the pallet 8 are configured to be fitted with a combination of several convex cones and concave cones.

一方、パレット８は、自動機械加工機６が具備する位置決め固定治具と同形状・同機能の治具を搭載した皿状の部材である。パレット８はこの位置決め固定治具で試料１３を固定し、自動搬送装置４を介して自動機械加工機６と自動加工受け渡し台３或いは製品受け取り台７との間を行き来する。   On the other hand, the pallet 8 is a dish-like member on which a jig having the same shape and function as the positioning and fixing jig provided in the automatic machining machine 6 is mounted. The pallet 8 fixes the sample 13 with this positioning fixture, and moves back and forth between the automatic machining machine 6 and the automatic processing delivery table 3 or the product receiving table 7 via the automatic conveying device 4.

パレット８は、自動機械加工機６上に位置決めされた状態で、自動機械加工機６に対する位置決め固定治具１１（ａ）の位置が高い外形寸法精度で定まるように製作されている。すなわち、自動機械加工機６が具備する位置決め固定治具１１（ａ）及びパレット８の製作精度は、例えば規格により機械試験片に要求される製作精度が±0.1mm以内であったと仮定すると、それと同範囲以内、もしくはそれ未満の±0.05mm等の外形寸法精度を確保されている必要がある。また、パレット８が具備する試料の位置決め固定治具１１（ｂ）についても同様の精度を確保されている必要がある。   The pallet 8 is manufactured so that the position of the positioning fixing jig 11 (a) with respect to the automatic machining machine 6 is determined with high external dimension accuracy while being positioned on the automatic machining machine 6. That is, the manufacturing accuracy of the positioning and fixing jig 11 (a) and the pallet 8 included in the automatic machining machine 6 is assumed to be within ± 0.1 mm, for example, according to the standard. It is necessary to ensure the accuracy of external dimensions such as ± 0.05mm within the same range or less. In addition, the same accuracy needs to be ensured for the sample positioning and fixing jig 11 (b) included in the pallet 8.

自動機械加工機６が試料を個別にハンドリングする機能を有する場合、そのハンドリング装置は試料を確実に把持可能な精度内に試料を設置し、保持できる治具でなければならない。自動機械加工機６が数種類存在する場合は、自動機械加工機６の種類毎に上記のようなパレット８を製作する。その場合、これらのパレット８は、外形寸法や重量がほぼ類似するように限定された数種類に規格化して製作されなければならない。例えば、平面形状が500mm×500mm、重量が50kg等である。このように、自動機械加工機６に具備された治具１１（ａ）、パレット８の外形寸法及びパレットに具備された位置決め固定治具１１（ｂ）によって加工精度が確保される。   When the automatic machine 6 has a function of handling samples individually, the handling device must be a jig that can set and hold the sample within an accuracy capable of reliably holding the sample. If there are several types of automatic machine 6, the pallet 8 as described above is manufactured for each type of automatic machine 6. In that case, these pallets 8 must be standardized and manufactured in a limited number of types so that the external dimensions and weight are substantially similar. For example, the planar shape is 500 mm × 500 mm, and the weight is 50 kg. As described above, the processing accuracy is ensured by the jig 11 (a) provided in the automatic machine 6, the outer dimensions of the pallet 8 and the positioning and fixing jig 11 (b) provided in the pallet.

また、パレット８には、そのパレット８を使用する自動機械加工機６の種類と加工に必要な情報を記録し、自動的に識別できる機能のある情報記録媒体９を装備するとよい。自動機械加工機６或いは自動搬送装置４は、この情報記録媒体９から、次の加工をどのように行うのか、次の加工をどの自動機械加工機６で行うのか、現状どこまで加工されたのか等の情報を読み取り、分担された自動加工や自動搬送を行う。   Further, the pallet 8 may be equipped with an information recording medium 9 having a function of recording the type of the automatic machine tool 6 using the pallet 8 and information necessary for processing and automatically identifying it. From the information recording medium 9, the automatic machine 6 or the automatic conveyance device 4 shows how the next machining is performed, which automatic machining machine 6 is used for the next machining, how far the current machining has been performed, and the like. Information is read, and shared automatic processing and automatic conveyance are performed.

図２にパレットの例を示す。図２（ａ）、２（ｃ）は帯鋸盤用のパレット例、図２（ｂ）、２（ｄ）は衝撃試験片用の自動機械加工機用のパレット例である。   FIG. 2 shows an example of a pallet. 2 (a) and 2 (c) are examples of a pallet for a band saw, and FIGS. 2 (b) and 2 (d) are examples of a pallet for an automatic machine for impact test pieces.

各パレット８は、パレットの基準点１０を有し、この点１０を基準としたパレット８上の所定位置に、鋸断する試料１３（ａ）、衝撃試験片用試料１３（ｂ）を設置・固定できる構造とし、パレット８への試料１３の設置・固定作業は作業者が行う。   Each pallet 8 has a reference point 10 of the pallet, and a sample 13 (a) to be sawed and an impact test piece sample 13 (b) are installed at predetermined positions on the pallet 8 with reference to this point 10. The structure is such that it can be fixed, and the operator performs installation and fixing work of the sample 13 on the pallet 8.

試料１３が設置・固定されたパレット８は、自動搬送装置４にて自動機械加工機６へ搬送された後、パレット８の基準点１０を基準として、自動機械加工機６上のパレット８の位置決め固定治具１１（ａ）により容易かつ正確に位置決め・固定される。これにより、自動機械加工機６に対する試料１３の位置が、パレット８の基準点１０を介して正確に再現される。   After the pallet 8 on which the sample 13 is set and fixed is conveyed to the automatic machining machine 6 by the automatic conveyance device 4, the pallet 8 on the automatic machining machine 6 is positioned with reference to the reference point 10 of the pallet 8. It is positioned and fixed easily and accurately by the fixing jig 11 (a). Thereby, the position of the sample 13 with respect to the automatic machining machine 6 is accurately reproduced via the reference point 10 of the pallet 8.

図３に、機械試験片の加工製造システムの要部構成を示す。試料の受け渡しは上述したようなパレット８を用いる自動搬送装置４によって複数の自動機械加工機６に対して行われる。作業者１４は必要最小限の特定個所に設置された自動加工受け渡し台３の位置にてパレット８への試料のセット、取り出しを行う。自動加工受け渡し台３と複数の自動機械加工機６との間のパレット８の搬送には、汎用の搬送装置を共通的に使用する。   FIG. 3 shows a main configuration of a mechanical test piece processing and manufacturing system. The sample is delivered to a plurality of automatic machining machines 6 by the automatic transfer device 4 using the pallet 8 as described above. The operator 14 sets and removes the sample on the pallet 8 at the position of the automatic processing delivery table 3 installed at the minimum necessary specific location. A general-purpose conveying device is commonly used for conveying the pallet 8 between the automatic machining transfer table 3 and the plurality of automatic machining machines 6.

自動加工受け渡し作業者１４（ａ）は、自動加工受け渡し台３にて試料をパレット８に設置・固定する。このとき、パレット８に付属する情報記録媒体９に、使用自動機械加工機６の種類や試料加工に必要な情報を書き込み記録する。   The automatic processing delivery operator 14 (a) installs and fixes the sample on the pallet 8 by the automatic processing delivery table 3. At this time, the information recording medium 9 attached to the pallet 8 writes and records the type of the automatic machining machine 6 used and information necessary for sample processing.

自動搬送装置４では、情報記録媒体９の記録情報を読み取り、自動的に無人搬送台車４（ｂ）に搬送指令を出す。無人搬送台車４（ｂ）は自動加工受け渡し台３から該パレット８を積載し、複数ある自動機械加工機６の中から情報記録媒体９により指定された使用自動機械加工機６まで搬送、移載する。   The automatic conveyance device 4 reads the recorded information on the information recording medium 9 and automatically issues a conveyance command to the automatic guided vehicle 4 (b). The automatic guided vehicle 4 (b) loads the pallet 8 from the automatic processing delivery table 3, and conveys and transfers the pallet 8 from a plurality of automatic machining machines 6 to the used automatic machining machine 6 designated by the information recording medium 9. To do.

自動機械加工機６は、無人搬送台車４（ｂ）から該パレット８を受け取ると、パレット８を把持・位置決め固定し、記録媒体９の記録情報を自動的に読み取り、試料の加工精度を遵守して指定された加工を行う。   When the automatic machine 6 receives the pallet 8 from the automatic guided vehicle 4 (b), the automatic machine 6 grips, positions and fixes the pallet 8, automatically reads the recorded information on the recording medium 9, and observes the processing accuracy of the sample. The specified machining is performed.

加工が完了すると、自動機械加工機６は自動搬送装置４にその旨を伝達し、自動搬送装置４は自動的に無人搬送台車４（ａ）に搬送指令を出す。無人搬送台車４（ａ）は自動機械加工機６から該パレット８を積載し、製品受け取り台７まで搬送、移載する。この場合、中間加工品であれば、必要に応じて自動加工受け渡し台３へ搬送してもよい。   When the machining is completed, the automatic machining machine 6 transmits a message to that effect to the automatic conveyance device 4, and the automatic conveyance device 4 automatically issues a conveyance command to the automatic guided vehicle 4 (a). The automatic guided vehicle 4 (a) loads the pallet 8 from the automatic machining machine 6 and conveys and transfers it to the product receiving table 7. In this case, if it is an intermediate processed product, it may be conveyed to the automatic processing delivery table 3 as necessary.

製品受け取り作業者１４（ｂ）は、製品受け取り台７に届けられたパレット８から試料を取り出し、パレット８に付属する情報記録媒体９の記録情報を回送情報に変更する。自動搬送装置４は、情報記録媒体９の記録情報を読み取り、自動的に無人搬送台車４（ａ）に搬送指令を出す。無人搬送台車４（ａ）は製品受け取り台７から空になった該パレット８を積載し、自動加工受け渡し台３まで搬送、移載する。   The product receiving worker 14 (b) takes the sample from the pallet 8 delivered to the product receiving table 7 and changes the recording information of the information recording medium 9 attached to the pallet 8 to the forwarding information. The automatic conveyance device 4 reads the recorded information on the information recording medium 9 and automatically issues a conveyance command to the automatic guided vehicle 4 (a). The unmanned transport cart 4 (a) loads the pallet 8 that has been emptied from the product receiving table 7, and transports and transfers the pallet 8 to the automatic processing delivery table 3.

本発明を適用することで、以下のような効果が得られた。
