Description

【０００１】
【発明の属する技術分野】
本発明は、組立ラインの部品納入方法に関する。
【０００２】
【従来の技術】
油圧ショベル等の建設機械やフォークリフト等の産業車両などのように比較的大きな機械を組み立てる組立ラインでは、コンベア上にその機械の組立ベースを設置して所定の生産速度で該コンベアを移動させ、組立工程順に順次部品を組み付けて行く方法が多く採用されている。この場合、組付け用の部品のうち、比較的大きな部品はコンベアの横に組立工程順に設けた供給部で供給するようにしているが、小物部品は組立機械毎に対応させて部品台車等に積載し、該部品台車を組立ライン近傍に予め設置して準備して置くようにしたものがある。
【０００３】
上記の部品台車に、各組立機械の必要部品を組立開始前に予め積載して準備するために、業者からの納入部品が収納された部品納入棚（ラック等）からの部品マーシャリング（これは、各機械の組立に必要な部品を集めて該組立機械に対応する部品台車にそれぞれ積載する作業のことである。）が行われる。図５及び図６には、このための従来の部品納入、マーシャリング業務工程例が示されており、以下、図５、図６を参照して従来の業務工程を説明する。
【０００４】
まず、部品納入業者はトラック等で部品を客先工場に納入し、納入伝票（現品表、納品書、受領書等）を納入受付部門に提出する（工程Ｓ１１）。なお、このときの部品搬送形態は、部品の形状や納入個数等に適合させて、しかも運搬時に傷を受け難い状態で搬送され、専用のパレットやプラスチック製ケース（通常、プラスチックコンテナと呼ばれるものであり、以下プラコンと略称する。）等が用いられることが多い。次に、納入受付部門は納入伝票（納品書）を受領し、受領書に受領印等を押して検収する（工程Ｓ１２）。次に、部品納入業者は前記トラック等で納入部品を工場内の入庫場に運搬する（工程Ｓ１３）。そして、入庫場に設けてある、図６に示すようなフローラック等からなる部品棚１に、収納する（工程Ｓ14a ）。なお、この部品棚１は各部品毎に収納場所が決められており、部品納入業者はそれぞれの部品に対応した収納場所に収納する。
【０００５】
この後、組立工場の工程係は、組立ラインの各機械の組立開始計画に従って、組立開始時間前に、図６に示すように、各組立機械に必要な部品を前記部品棚１からそれぞれ取り出して、各組立機械に対応して設けられた部品台車２に積載する。そして、全ての部品を積載したら（マーシャリングの完了）、その部品台車２を組立ラインのスタート位置近傍に組立計画順に整列配置して、準備を完了する（工程Ｓ14b ）。この後、組立開始時間になったら、組立ライン上に組立機番に対応する上記部品台車２を載置し、組立をスタートする（工程Ｓ１５）。
【０００６】
一方、前記工程Ｓ１４で、部品棚１から部品をマーシャリングした後、空パレットや空プラコン等が発生したら、工程係はこれを集めて運搬し（工程Ｓ１６）、工場内の所定の集積場に集積して置く（工程Ｓ１７）。この後、部品納入業者は、部品を納入した際に、帰る途中で上記集積場から自社専用の空パレットや空プラコン等を回収して持ち帰るようにする（工程Ｓ18a ）。
【０００７】
なお、上述したような組立ラインの部品納入方法に関する先行技術文献は見当たらない。
【０００８】
【発明が解決しようとする課題】
しかしながら、従来の部品納入及びマーシャリングの方法には、次に述べるような幾つかの問題があり、改善が強く求められている。
近年の多品種少量生産の傾向に伴なって、納入部品点数が大幅に増大しているため、部品棚１の各収納場所からそれぞれの部品を取り出して、各組立機械に対応した部品台車にマーシャリングするのに非常に時間を要しており、生産能率を上げる上で大きな問題となっている。
【０００９】
また、部品運搬用のパレット、プラコン等を紛失することがあり、部品納入業者はこれらを確実に回収することができない場合が多いため、この無駄な損失によるコストアップを招いている。
さらに、部品運搬時に部品の破損や損傷を防止するための緩衝材や包装材等の副資材は、部品をパレット、プラコン等から取り出すまでパレット、プラコン等内に残っており、部品納入業者に回収されず、工場の産業廃棄物として処理される。このため、工場の廃棄物処理コストが上がり、トータルの製作コストのアップを招くことになる。また、この緩衝材等副資材の廃棄は資源の有効活用の面からも重要な問題となっている。
【００１０】
本発明は、上記の問題点に着目してなされたもので、組立ラインの部品マーシャリングの能率を向上でき、また部品運搬時のパレット、プラコン等の運搬用資材や緩衝材等の副資材を確実に再活用できるようにする組立ラインの部品納入方法を提供することを目的としている。
【００１１】
【課題を解決するための手段、作用及び効果】
上記目的を達成するため、第１発明は、組立ラインの部品納入方法において、納入部品名、納入場所を記入した現品票を、機械１台に必要な部品毎に添付し、前記現品票に記入した納入場所と同じ納入場所を記入した台車標示板１３が設けられた部品台車１０に、部品納入業者が前記納入部品を現品票と共に収納し、この後、前記部品台車１０は組立ラインに移動され、組立工程順に従って、部品が部品台車１０から取り出され機械を組み立てるようにした方法としている。
【００１２】
第１発明によれば、部品納入業者が、現品票によって指定された納入場所にある部品台車に直接収納するので、従来行っていたような収納棚からの部品マーシャリング作業が不要となり、生産能率を大幅に向上できる。また、部品納入業者は上記の部品台車へ直接部品を収納した後、空パレット、空プラコン等の運搬用資材、および緩衝材等の副資材があれば、それをその場で回収するので、紛失することが無く確実に回収でき、再使用することによりトータルコストを低減できる。さらに、これにより、工場内の産業廃棄物処理量を減少させることができるので、製造にかかるトータルコストを低減できると共に、工場廃棄物を発生させない（いわゆる、ゼロエミッション）という近年の環境保護の思想にも適合させることができる。
【００１３】
第２発明は、組立ラインの部品納入方法において、納入部品名、納期及び納入時間を記入した現品票を、機械１台に必要な部品毎に添付し、部品台車に組立日及び組立開始時間を記入した台車標示板が設けられ、前記現品票に記入した納期及び納入時間と、前記台車標示板に記入した組立日及び組立開始時間とが、同じ日付及び時刻である前記部品台車に、部品納入業者が前記納入部品を現品票と共に収納し、この後、前記部品台車は組立ラインに移動され、組立工程順に従って、部品が部品台車から取り出され機械を組み立てるようにした方法としている。
【００１４】
第２発明によれば、第１発明と同様の効果が得られるとともに、さらに部品台車と組立ラインとの時間的な対応付けが容易であり、部品納入タイミングが分かり易く、ライン稼動の時間管理が正確にできる。
【００１５】
第３発明は、第１又は第２発明に基づく組立ラインの部品納入方法において、前記部品台車に互いに区切られた複数の収納区分け部が設けられ、前記現品票には該納入部品を収納すべき収納区分け部の位置が記入されている方法としている。
【００１６】
第３発明によれば、現品票に該納入部品を収納すべき収納区分け部の位置が記入されているため、部品の納入ミスや未納等が無いかのチェックが容易であり、納入部品の現品確認が確実にできると共に、納入時に納入ミス、欠品等がすぐに分かるので、その対応処置が早期にできる。
【００１７】
第４発明は、第１、第２又は第３発明に基づく組立ラインの部品納入方法において、前記部品台車は、各組立機械に対応させて組立ラインと共に移動させる方法としている。
【００１８】
第４発明によれば、各組立機械に対応させてそれぞれの部品台車も移動させるので、部品台車からの部品の取り出しが容易であり、組立性を向上できる。
【００１９】
第５発明は、第１、第２、第３又は第４発明に基づく組立ラインの部品納入方法において、前記部品台車には、１機種１台分の部品を対応させて積載した方法としている。
【００２０】
第５発明によれば、各部品台車の部品の過不足が部品納入段階で正確にチェックできるため、納入部品の未納、欠品等を早期に発見でき、対応処置を早く取れるので、組立ラインを安定して稼動させることができる。
【００２１】
【発明の実施の形態】
以下に、本発明の実施形態を図面を参照して詳細に説明する。
【００２２】
図１は、本発明に係る業務工程を示すフローであり、まず図１により部品納入の業務工程を説明する。
工程Ｓ１から工程Ｓ３までは、工程Ｓ１１から工程Ｓ１３までと同じである。この後、部品納入業者は、入庫場の、納入伝票の現品票によって指定された部品台車の、指定された収納位置に直接各部品を現品票と一緒に収納する（工程Ｓ４）。
【００２３】
次に、組立開始時間前に、工程係はその部品台車を組立ラインのスタート位置近傍に組立順に整列配置して組立準備を行い、組立開始時間になったら、組立ライン上に組立機番に対応する上記部品台車を載置し、組立をスタートさせる（工程Ｓ５）。一方、部品納入業者は、前記工程Ｓ４の後、空パレット、空プラコン等、及び緩衝材等の副資材があればその場で回収する（工程Ｓ８，９）。
【００２４】
ここで、前記工程Ｓ４における、入庫場の部品台車及びその部品納入方法について、説明をする。
図２は、実施形態に係る入庫場の説明図である。図２に示すように、入庫場には、従来の部品棚１（図６参照）の代わりに、それぞれ台車標示板１３-1、１３-2、…１３-nを有する複数の部品台車１０-1、１０-2、…１０-nを配列している。これらの部品台車１０-1、１０-2、…１０-nは、例えば組立開始時間順に、組立機械種別に配列するようにする。
【００２５】
図３は部品台車の斜視図である。部品台車１０は、キャスタ、車輪等の移動手段１１を下部に備え、移動手段１１の上部には複数段の収納棚１２を備え、最上段（本実施形態では４段目）には見え易い位置に前記台車標示板１３が設けられ、また複数の仕切り部材１４が設けられている。また、移動手段１１には、足踏み式のストッパ装置１５が設けられており、該部品台車１０が動かないように任意の位置で固定できるようになっている。
【００２６】
台車標示板１３には、図４に示すように、各部品台車１０を特定するための情報が記入されており、例えば、ラインオン日（組立日に相当する。）ラインオン時間（組立開始時間に相当する。）、機種コード、機番等が記入されている。
【００２７】
一方、図４に示すように、現品票２１には、部品の特定事項及び納入場所指定事項が記入されている。部品特定事項としては、部品名、納入数、それらのバーコード等が、また納入場所指定事項としては、納期、納入時間、荷降場名、保管場所名、及びこれらの指示コード、バーコード等が記入されている。
上記の納期及び納入時間は、それぞれ台車標示板１３のラインオン日及びラインオン時間に対応させている。また、上記の荷降場名は、当該部品台車１０のある場所を指し、保管場所名は当該部品台車１０の収納すべき収納棚の段数に対応させている（例えば、保管場所「２Ｘ−１Ａ４−Ｄ４」は４段目を表している）。したがって、部品納入業者が各部品台車１０の部品を収納するときには、現品票２１と台車標示板１３との記入事項を対応させて、指定された部品台車１０の指定された段の位置に収納している。
【００２８】
尚、上記実施形態で、部品台車１０は水平方向に区切られた複数段の棚を有する例で示したが、これに限定するものでなく、移動自在で、かつ納入部品を収納可能な収納区分け部を備えていればよく、例えば、下部に移動手段を備え、かつ上方に開口した容器内に前後左右方向に区切られた複数の仕切り板等で互いに区切られた複数の収納区分け部を備えたものであってもよい。また、収納区分け部の数も上記実施形態の数（４段）に限定されない。
【００２９】
以上のことから、本発明に係る部品納入方法により、以下の効果を奏する。
部品納入業者が、納入伝票の現品票によって指定された部品台車１０の、指定された位置（上記例では段）に直接収納するので、従来行っていたような収納棚からの部品マーシャリング作業が不要となり、生産能率を大幅に向上できる。
また、部品納入業者は上記の部品台車１０へ直接部品を収納した後、空パレット、空プラコン等の搬送用資材、および緩衝材等の副資材があれば、それをその場で回収するので、紛失することが無く確実に回収することができ、再使用することによりトータルコストを低減できる。
【００３０】
さらに、これにより、工場内の産業廃棄物処理量を減少させることができるので、製造にかかるトータルコストを低減できると共に、廃棄物を発生させないという近年の環境保護（ゼロエミッション）の思想にも適合させることができる。
また、部品を納入する時の運送荷姿をパレット上やプラコン内等に限定する必要が無くなり、従来に比して自由度が増すので、運送コストを低減できる。
【００３１】
さらにまた、部品台車１０に複数の収納区分け部を設け、現品票には当該納入部品を収納すべき収納区分け部を記載してそれぞれの部品納入位置を指定するので、部品の納入ミスや未納等が無いかのチェックが容易であり、納入部品の現品確認が確実にできると共に、納入時に納入ミス、欠品等がすぐに分かるので、その対応処置が早期にできる。
また、部品台車１０に１機種１台分の部品を対応させて積載するため、各部品台車１０の部品の過不足が部品納入段階で正確にチェックできる。これにより、納入部品の未納、欠品等の不具合を早期に発見でき、対応処置を早く取れるので組立ラインを安定して稼動させることができる。
【００３２】
また、それぞれの部品台車１０をコンベアと共に移動させることにより、各組立機械の移動に対応させて移動できるので、部品台車からの部品の取り出しが容易であり、組立性を向上できる。
また、部品台車１０と組立ラインとの時間的な対応付けが容易であり、部品納入タイミングが分かり易く、ライン稼動の時間管理が正確にできる。

BACKGROUND OF THE INVENTION
The present invention relates to a part delivery method for an assembly line.
[0002]
[Prior art]
In an assembly line that assembles relatively large machines such as construction machines such as hydraulic excavators and industrial vehicles such as forklifts, the assembly base of the machine is installed on the conveyor and the conveyor is moved at a predetermined production speed. Many methods of assembling parts sequentially in the order of processes are employed. In this case, among the parts for assembly, relatively large parts are supplied by a supply unit provided in the order of the assembly process on the side of the conveyor, but small parts are provided for each assembly machine in a parts cart or the like. There are some which are loaded and the parts cart is installed and prepared in the vicinity of the assembly line in advance.
[0003]
In order to prepare in advance the necessary parts of each assembly machine on the above parts cart before starting assembly, parts marshalling from parts delivery shelves (rack, etc.) containing parts delivered from suppliers (this is This is an operation of collecting parts necessary for assembling each machine and loading them on a parts cart corresponding to the assembling machine. 5 and 6 show examples of conventional parts delivery and marshalling business processes for this purpose. Hereinafter, the conventional business processes will be described with reference to FIGS.
[0004]
First, the parts supplier delivers the parts to the customer factory by truck or the like, and submits a delivery slip (inventory table, delivery note, receipt, etc.) to the delivery reception department (step S11). In this case, the parts transportation form is adapted to the shape of the parts, the number of parts delivered, etc., and is transported in a state where it is not easily damaged by transportation, and a dedicated pallet or plastic case (usually called a plastic container) And abbreviated as “PLACON”) in many cases. Next, the delivery reception department receives the delivery slip (delivery note) and presses the receipt stamp on the receipt to inspect (step S12). Next, the parts supplier transports the delivered parts to the garage in the factory using the truck or the like (step S13). And it stores in the parts shelf 1 which consists of a flow rack etc. as shown in FIG. 6 provided in the warehousing place (process S14a). In addition, the storage location of the component shelf 1 is determined for each component, and the component supplier stores the component shelf 1 in a storage location corresponding to each component.
[0005]
Thereafter, the assembly plant process person takes out the parts necessary for each assembly machine from the parts shelf 1 as shown in FIG. 6 before the assembly start time according to the assembly start plan of each machine in the assembly line. Then, it is loaded on a parts cart 2 provided corresponding to each assembly machine. When all the parts are loaded (marshalling is completed), the parts cart 2 is arranged in the order of the assembly plan in the vicinity of the start position of the assembly line, and the preparation is completed (step S14b). Thereafter, when the assembly start time is reached, the parts cart 2 corresponding to the assembly machine number is placed on the assembly line, and assembly is started (step S15).
[0006]
On the other hand, after marshalling a part from the parts shelf 1 in the step S14, if an empty pallet, an empty placon, or the like is generated, the process clerk collects and transports it (step S16) and collects it at a predetermined collection site in the factory. (Step S17). Thereafter, when the parts are delivered, the parts supplier collects their own empty pallets, empty placons, etc. from the collection site on the way home, and takes them home (step S18a).
[0007]
In addition, there is no prior art document relating to the assembly line component delivery method as described above.
[0008]
[Problems to be solved by the invention]
However, the conventional parts delivery and marshalling methods have several problems as described below, and improvement is strongly demanded.
As the number of parts delivered has increased significantly with the recent trend of high-mix low-volume production, each part is taken out from each storage location in the parts shelf 1 and marshalled into a parts cart corresponding to each assembly machine. It takes a very long time to do so, which is a big problem in raising the production efficiency.
[0009]
In addition, parts transportation pallets, placons, etc. may be lost, and parts suppliers are often unable to reliably collect them, leading to increased costs due to this useless loss.
In addition, auxiliary materials such as cushioning materials and packaging materials to prevent damage and damage to the parts during transportation remain in the pallets, plastic computers, etc. until the parts are removed from the pallets, plastics, etc., and are collected by the parts suppliers. It is not treated as industrial waste in the factory. For this reason, the waste disposal cost of a factory rises and the total production cost is raised. In addition, disposal of secondary materials such as cushioning materials is an important problem from the viewpoint of effective use of resources.
[0010]
The present invention has been made paying attention to the above-mentioned problems, and can improve the efficiency of parts marshalling in the assembly line, and can reliably transport materials such as pallets and plastic parts during transportation of parts and auxiliary materials such as cushioning materials. The purpose is to provide an assembly line parts delivery method that can be reused.
[0011]
[Means, actions and effects for solving the problems]
In order to achieve the above object, according to the first invention, in the parts delivery method of the assembly line, an actual product slip in which the name of the delivered part and the delivery location are entered is attached to each required part of one machine, and the actual product slip is entered. The parts supplier stores the delivered parts together with the actual product slip in the parts cart 10 provided with the cart sign board 13 in which the same delivery location is entered, and then the parts cart 10 is moved to the assembly line. According to the assembly process order, the parts are taken out from the parts cart 10 and the machine is assembled.
[0012]
According to the first invention, since the parts supplier directly stores the parts in the parts cart at the delivery place specified by the actual product slip, the parts marshalling work from the storage shelves, which has been conventionally performed, becomes unnecessary, and the production efficiency is improved. Can greatly improve. In addition, after the parts supplier stores the parts directly in the above parts cart, if there are transporting materials such as empty pallets, empty placons, and auxiliary materials such as cushioning materials, they will be collected on the spot and lost. It can be reliably recovered without re-use, and the total cost can be reduced by reuse. In addition, the amount of industrial waste processed in the factory can be reduced, thereby reducing the total cost for manufacturing and not generating factory waste (so-called zero emission). Can also be adapted.
[0013]
The second aspect of the invention is a part delivery method for an assembly line, in which an invoice that includes a delivery part name, a delivery date, and a delivery time is attached to each part required for one machine, and an assembly date and an assembly start time are attached to the parts cart. Deliver parts to the parts cart, which is provided with the entered cart sign board, and the delivery date and delivery time entered on the product label and the assembly date and assembly start time entered on the cart sign board are the same date and time The supplier stores the delivered parts together with the actual product slip, and thereafter, the parts cart is moved to the assembly line, and the parts are taken out from the parts cart according to the assembly process order to assemble the machine .
[0014]
According to the second invention, the same effects as those of the first invention can be obtained, and the time correspondence between the parts cart and the assembly line is easy, the parts delivery timing is easy to understand, and the time management of the line operation can be performed. Can be accurate.
[0015]
According to a third aspect of the present invention, in the parts delivery method for an assembly line according to the first or second aspect, the parts cart is provided with a plurality of storage division parts separated from each other , and the delivered parts should be stored in the actual product slip It is a method in which the position of the storage section is entered .
[0016]
According to the third invention, since the position of the storage section where the delivered part is to be stored is entered on the actual product slip, it is easy to check whether there is a delivery error or non-delivery of the part. In addition to ensuring confirmation, delivery errors and missing items can be immediately identified at the time of delivery, so that countermeasures can be taken early.
[0017]
According to a fourth aspect of the present invention, in the assembly line component delivery method according to the first, second or third aspect of the present invention, the component carriage is moved together with the assembly line in correspondence with each assembly machine .
[0018]
According to the fourth aspect of the invention, since the parts carts are also moved corresponding to the respective assembly machines, it is easy to take out the parts from the parts cart, and the assemblability can be improved.
[0019]
According to a fifth aspect of the present invention, there is provided an assembly line component delivery method according to the first, second, third or fourth aspect of the present invention, wherein the component cart is loaded with corresponding parts for one model.
[0020]
According to the fifth invention, since the excess or deficiency of the parts of each parts cart can be checked accurately at the part delivery stage, undelivered parts, missing parts, etc. can be detected at an early stage, and countermeasures can be taken quickly. It can be operated stably.
[0021]

Parts identification items include parts name, number of deliveries and their barcodes, and delivery location designation items include delivery date, delivery time, unloading site name, storage location name, and their instruction codes, barcodes, etc. Is filled in.
The delivery date and delivery time described above correspond to the line-on date and line-on time of the carriage sign plate 13 respectively. The unloading site name indicates a location where the parts cart 10 is located, and the storage location name corresponds to the number of storage shelves to be stored in the parts cart 10 (for example, the storage location “2X-1A4”). -D4 "represents the fourth stage). Therefore, when the parts supplier stores the parts of each parts cart 10, the items on the product label 21 and the cart sign board 13 are made to correspond to each other and stored in the designated position of the designated parts cart 10. ing.
[0028]
In the above embodiment, the parts cart 10 is shown as an example having a plurality of shelves partitioned in the horizontal direction. However, the present invention is not limited to this, and the storage cart is movable and can store delivered parts. For example, provided with moving means in the lower part, and provided with a plurality of storage division parts separated from each other by a plurality of partition plates etc. divided in the front-rear and left-right directions in a container opened upward It may be a thing. Further, the number of storage compartments is not limited to the number (four steps) of the above embodiment.
[0029]
From the above, the parts delivery method according to the present invention has the following effects.
The parts supplier stores directly in the specified position (in the above example, the stage) of the parts cart 10 specified by the delivery slip, so there is no need to marshal the parts from the storage shelf as was done in the past. Thus, the production efficiency can be greatly improved.
In addition, after the parts supplier stores the parts directly in the parts cart 10 described above, if there are transporting materials such as empty pallets, empty placons, and auxiliary materials such as cushioning materials, they will be collected on the spot. It can be reliably recovered without being lost, and the total cost can be reduced by reuse.
[0030]
In addition, this reduces the amount of industrial waste handled in the factory, which reduces the total cost of manufacturing and is compatible with the recent environmental protection (zero emission) concept of not generating waste. Can be made.
In addition, it is not necessary to limit the appearance of the transportation cargo when delivering the parts to the pallet or the inside of the placon, and the degree of freedom is increased as compared with the conventional one, so that the transportation cost can be reduced.
[0031]
Furthermore, since the parts cart 10 is provided with a plurality of storage sorting sections, and the actual product slip describes the storage sorting sections where the delivery parts should be stored and designates the delivery positions of the parts. It is easy to check whether there are any defects, and it is possible to confirm the actual product of delivered parts, and at the time of delivery, it is possible to immediately identify delivery mistakes, missing parts, etc., so that countermeasures can be taken early.
Since parts for one model are loaded in correspondence with the parts cart 10, the excess or deficiency of the parts of each parts cart 10 can be checked accurately at the parts delivery stage. As a result, problems such as non-payment of delivered parts, missing parts, etc. can be detected at an early stage, and countermeasures can be taken quickly, so that the assembly line can be operated stably.
[0032]
Further, by moving the respective parts carts 10 together with the conveyors, the parts carts 10 can be moved in accordance with the movements of the respective assembly machines. Therefore, it is easy to take out the parts from the parts cart, and the assemblability can be improved.
Further, the time correspondence between the parts cart 10 and the assembly line is easy, the parts delivery timing is easy to understand, and the time management of the line operation can be performed accurately.
