Description

作業効率算出システム、方法及びプログラムWork efficiency calculation system, method and program
　本発明は、倉庫で行う流通加工作業の作業効率を算出する作業効率算出システム、方法及びプログラムに関する。 The present invention relates to a work efficiency calculation system, method, and program for calculating the work efficiency of distribution processing work performed in a warehouse.
　一般に、工場で生産された製品が、商品として市場に流通するまでには様々な工程を経る。例えば、物流に適した大きさや形状に揃える工程、製品が所定の規格に適合したものであるかを検品する工程、生産過程で異物（針など）の残留がないか検品する工程、製品を包装する工程、小売店用のタグや値札を付ける工程、更には、贈答用にラッピングする工程など、消費者の手に届くまで、商品の特性に合わせて必要な流通加工作業がなされる。 In general, products produced in factories go through various processes before being distributed to the market as products. For example, the process of arranging the size and shape suitable for distribution, the process of inspecting whether the product conforms to the prescribed standards, the process of inspecting the product for foreign substances (needles, etc.) remaining in the production process, and the packaging of the product. Necessary distribution processing work is done according to the characteristics of the product until it reaches the consumer, such as the process of attaching tags and price tags for retail stores, and the process of wrapping for gifts.
　物流倉庫では、工場で一定レベルの検品を終了した製品が到着すると、荷主からの要請に応じて、上述のような流通加工作業を担当することがある。具体的には、値付け、タグ付け、ラッピング、検針等の作業が挙げられる。このような流通加工作業は、倉庫から出荷されると小売店で販売できるレベルに付加価値を生じさせる工程である。 In distribution warehouses, when products that have completed a certain level of inspection at the factory arrive, they may be in charge of the distribution processing work described above at the request of the shipper. Specific examples include operations such as pricing, tagging, wrapping, and meter reading. Such a distribution processing operation is a process of adding value to a level that can be sold at retail stores once shipped from the warehouse.
　ところで、物流倉庫では、荷物の入出庫数や商品の種類数は、商品（＝需要）によって決まってくるため流動的である。少品種の商品を多数取り扱う時もあれば、多品種少数となる場合もある。むろん、製品・商品の形態も様々であり、機械化が困難で、上述の付加価値を付ける流通加工作業では人に頼らざるを得ない。更には、倉庫への入出庫数が流動的であることから、作業者の入れ替わりも多い。 By the way, in distribution warehouses, the number of incoming and outgoing packages and the number of types of products are determined by the products (= demand), so they are fluid. There are times when we handle a large number of products of a small variety, and there are times when we handle a large number of products in a small number. Of course, there are various forms of products and commodities, and it is difficult to mechanize, and the value-added distribution processing work described above must rely on people. Furthermore, since the number of goods entering and leaving the warehouse is fluid, there is a high turnover of workers.
　このような背景から、物流倉庫での流通加工作業では、作業者個人の生産性を把握しづらく、作業を一定レベルに維持することが困難である。 Due to this background, it is difficult to grasp the productivity of individual workers in distribution processing work at distribution warehouses, and it is difficult to maintain work at a certain level.
　物流倉庫で作業を行う作業者を管理する方法として、例えば、流通加工作業を行う作業者の作業時間を異なる物流施設で統一的に管理するシステムが知られている（特許文献１）。 As a method of managing workers who work in distribution warehouses, for example, a system is known that uniformly manages the working hours of workers who perform distribution processing work in different distribution facilities (Patent Document 1).
特開２０１６－２２４６７５号公報JP 2016-224675 A
　しかしながら、特許文献１では、作業者が、荷受、入庫検品、流通加工、検品等の各作業を始める際に、何の作業を始めるか入力する手間がかかり、作業を変更する毎にタブレットを操作する手間が生じる。加えて、特許文献１では、単に作業者が行っている作業時間を計測するのみで、作業者がこれらの作業の生産性を向上するための指標をシステムが提示することができない。 However, in Patent Document 1, when a worker starts each work such as receiving goods, inspecting incoming goods, distribution processing, and inspecting goods, it takes time and effort to input what work to start, and the tablet is operated every time the work is changed. It takes time to do it. In addition, in Patent Literature 1, the system simply measures the work time of the worker and cannot present an index for the worker to improve the productivity of the work.
　作業者が行う流通加工作業は、出荷に向けて工程が進む作業（以下「本作業」という。）とそれ以外の付随作業（準備作業）に分けられる。
　本発明者らは、本作業だけでなく、準備作業（付随作業）にも、多大な時間を要する場合があるため、生産性を向上させるには、その両方の工程を見直す必要があることに着目した。 The distribution processing work performed by the worker is divided into work that advances the process toward shipping (hereinafter referred to as "main work") and other incidental work (preparatory work).
The present inventors have found that not only this work but also the preparation work (accompanied work) may take a lot of time, so it is necessary to review both processes in order to improve productivity. I paid attention.
　例えば、準備作業（付随作業）の時間が多大となる場合には、倉庫管理者は、準備を素早く行えるような工程への見直しや、作業スペースの配分の見直しを図ることなどが考えられる。 For example, if the preparation work (accompanying work) takes a lot of time, the warehouse manager can consider reviewing the process so that preparations can be done quickly, and reviewing the allocation of work space.
　また、複数作業者が同じ作業に従事していて、個人差が大きくなるような場合には、作業マニュアルを見直したり、慣れない作業者に対して適時に声かけしたりすることで、生産性を向上できるようになる、と考えられる。 In addition, when multiple workers are engaged in the same work and there are large individual differences, productivity can be improved by reviewing the work manual and talking to unfamiliar workers in a timely manner. can be improved.
　このような改善施策を適時に実行するために、作業者が「本来必要な作業にどれくらい従事しているか」、「準備作業にどれくらい時間がかかっているか」をある程度リアルタイムに、かつ、客観的に把握できるのが望ましい。 In order to implement such improvement measures in a timely manner, it is necessary to measure in real time and objectively, to some extent, how long workers are engaged in the originally necessary work and how long preparation work takes. It is desirable to be able to grasp
　そこで、本発明は、作業者別に流通加工作業の作業状態を解析し、本作業時間、付随作業時間を把握することが可能な、作業効率算出システムを提供することを目的とする。 Therefore, it is an object of the present invention to provide a work efficiency calculation system that can analyze the work status of distribution processing work for each worker and grasp the main work time and incidental work time.
　なお、流通加工作業とは、狭義には、流通において付加価値を与える作業の事であるが、本発明では、この狭義の作業に加えて、流通における不可避な作業、例えば、梱包作業、ピッキング等を含む作業全般を含む。 In a narrow sense, distribution processing work means work that adds value in distribution. Including work in general.
　また、本発明において、本作業時間とは、出荷に向けて工程が進む作業の時間を示し、付随作業時間とは、本作業のための準備時間を含む、本作業を成立させるために必要な付加的作業に要する時間やそれ以外の時間を示す。 In addition, in the present invention, the main work time indicates the time for the work to progress toward shipping, and the incidental work time includes the preparation time for the main work, and the time required to complete the main work. Indicates the time required for additional work and other time.
　本発明では、以下のような解決手段を提供する。 The present invention provides the following solutions.

　以下、添付図面を参照して、本発明を実施するための形態（以下、実施形態）について詳細に説明する。以降の図においては、実施形態の説明の全体を通して同じ要素には同じ番号又は符号を付している。 Hereinafter, with reference to the attached drawings, the modes for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail. In subsequent figures, the same numbers or symbols are attached to the same elements throughout the description of the embodiments.
　＜基本概念／基本構成＞
　図１は、本発明の実施形態に係る作業効率算出システムの概要を説明する図である。作業効率算出システム１は、倉庫内で作業者５ａ～５ｄが行う作業（ここでは、梱包作業）を撮影するカメラ３０と、カメラ３０に接続され、作業者５ａ～５ｄ毎の梱包作業の作業効率を算出する作業効率出力装置１００と、作業効率出力装置１００にネットワークを介して接続され、算出された作業効率が表示される管理者端末５０と、を含む。 <Basic Concept/Basic Configuration>
FIG. 1 is a diagram illustrating an overview of a work efficiency calculation system according to an embodiment of the present invention. The work efficiency calculation system 1 is connected to a camera 30 that captures the work (here, packing work) performed by the workers 5a to 5d in the warehouse, and is connected to the camera 30, and calculates the work efficiency of the packing work for each of the workers 5a to 5d. and an administrator terminal 50 connected to the work efficiency output device 100 via a network and displaying the calculated work efficiency.
　作業効率算出システム１において、カメラ３０は、本実施形態では、複数の作業者５ａ～５ｄの作業を撮影する。作業者５ａ～５ｄは、それぞれの作業台６ａ～６ｄにおいて、オリコン（折り畳みコンテナ）７ａ～７ｄで、商品８ａ～８ｄを梱包する作業を行っており、梱包後の商品がコンベア４０に載せられ搬送される。 In the work efficiency calculation system 1, the camera 30 photographs the work of a plurality of workers 5a to 5d in this embodiment. The workers 5a to 5d are working to pack the products 8a to 8d with folding containers (folding containers) 7a to 7d on the workbenches 6a to 6d, respectively. be done.
　管理者端末５０は、本実施形態では、スマートフォンであるが、タブレットや他のネットワーク接続可能な端末であってもよい。作業効率出力装置１００は、本実施形態では、クラウドサーバであり、例えば、倉庫の管理者（物流会社等）に管理される。 The administrator terminal 50 is a smartphone in this embodiment, but may be a tablet or other network connectable terminals. The work efficiency output device 100 is a cloud server in this embodiment, and is managed by, for example, a warehouse manager (such as a distribution company).
　なお、本実施形態においては、流通における加工作業のうち、倉庫で行う梱包作業を例に挙げて説明している。倉庫で行う梱包作業には、梱包する商品を保管箱から取り出したり、商品をオリコンへ入れたり、値札を付けるなどの予め定められた特定の作業があり、これら出荷に向けて工程が進む特定の作業を「本作業」としている。また、保管箱を作業台へ近づける作業のように、工程は進まないが本作業を行うために必要な作業やそれ以外の作業を本明細書では「付随作業」としている。また、管理者やその他の人物から作業者に対し指導や確認作業を行っている場合も、本作業ではない作業の一つとして、付随作業の中に含めるようにしてもよい。また作業者の画像を取得できなかった時には、作業者が何らかの理由で作業場所を離れなければならなかったと認識し、その時間を付随作業の中に含めるようにしてもよい。このような付随作業に、必ずしも必要とはいえない工程（不要な作業工程）が内在しやすい。 In addition, in the present embodiment, among the processing operations in distribution, the packing operation performed in the warehouse is taken as an example. The packing work performed in the warehouse includes predetermined specific tasks such as taking the product to be packed out of the storage box, putting the product into a container, and attaching a price tag. The work is called "main work". Further, in this specification, "accompanied work" includes work necessary for performing the main work and other work, such as the work of bringing the storage box closer to the workbench, although the process does not progress. In addition, even when a manager or other person is instructing or confirming the worker, it may be included in the incidental work as one of the works other than the main work. Also, when the image of the worker cannot be acquired, it may be recognized that the worker had to leave the work place for some reason, and the time may be included in the incidental work. Such incidental work tends to include processes that are not necessarily required (unnecessary work processes).
　作業効率算出システム１は、作業者５ａ～５ｄの所定の作業（本実施形態では梱包作業）を映した画像をカメラ３０から取得する。梱包作業を映した画像は、動画であってもよいし、静止画であってもよい。 The work efficiency calculation system 1 acquires from the camera 30 an image showing the predetermined work (packing work in this embodiment) of the workers 5a to 5d. The image showing the packing work may be a moving image or a still image.
　次に、作業効率算出システム１は、取得した画像を解析して、当該画像を、出荷に向けて工程が進む本作業を映した画像であるか、又は、前記本作業に該当しない準備作業のような付随作業を映した画像であるか否かを分類する。 Next, the work efficiency calculation system 1 analyzes the acquired image, and determines whether the image is an image showing the main work progressing toward shipping, or an image of the preparatory work that does not correspond to the main work. The image is classified as to whether or not it is an image that reflects such incidental work.
　次に、作業効率算出システム１は、分類した各画像の撮影時間から、本作業の作業時間及び付随作業の作業時間を、作業者５ａ～５ｄ毎に算出する。そして、作業効率算出システム１は、算出した本作業の作業時間と、付随作業の作業時間を作業者毎に出力する。出力した内容は、例えば、管理者端末５０の表示部に表示される。 Next, the work efficiency calculation system 1 calculates the work time of the main work and the work time of the incidental work for each of the workers 5a to 5d from the shooting time of each classified image. Then, the work efficiency calculation system 1 outputs the calculated working time of the main work and the calculated working time of the incidental work for each worker. The output contents are displayed on the display unit of the administrator terminal 50, for example.
　このように、作業者が本作業を行っている作業時間と、付随作業を行っている作業時間を算出し、作業者５ａ～５ｄ毎に流通加工作業の作業効率を可視化することができる。 In this way, it is possible to calculate the work hours during which the workers are performing the main work and the work hours during which the workers are performing the incidental work, and visualize the work efficiency of the distribution processing work for each of the workers 5a to 5d.
　その結果、例えば、本作業に入る前の付随作業の時間が多大となる場合には、作業者の管理者は、準備作業に時間を要していると判断し、準備を素早く行えるような工程への見直しや、作業スペースの配分の見直しを図ることができる。 As a result, for example, if the incidental work before starting the main work takes a lot of time, the worker's manager determines that the preparatory work takes time, and implements a process that allows quick preparation. It is possible to review the work space and review the allocation of work space.
　また、複数作業者が同じ作業に従事しており、個人差が大きくなるような場合には、作業マニュアルを見直したり、慣れない作業者に対して適時に声かけしたりすることで、生産性を向上できるようになる。 In addition, when multiple workers are engaged in the same work and there are large individual differences, productivity can be improved by reviewing the work manual and talking to unfamiliar workers in a timely manner. be able to improve

　図２は、本発明の実施形態に係る作業効率算出システムの機能構成を示す図である。作業効率算出システム１は、カメラ３０と、カメラ３０と接続された作業効率出力装置１００と、作業効率出力装置１００とネットワーク３を介して接続された管理者端末５０と、を備える。なお、本実施形態では、作業効率出力装置１００と管理者端末５０とは別の装置として説明するが、管理者端末５０を省略し、後述する管理者端末５０の機能を、作業効率出力装置１００が備えてもよい。また、その逆に、作業効率出力装置１００を省略し、後述する作業効率出力装置１００の機能を、管理者端末５０が備えるようにしてもよく、その場合には、カメラ３０は管理者端末５０に接続される。 <Functional configuration>
FIG. 2 is a diagram showing the functional configuration of the work efficiency calculation system according to the embodiment of the present invention. The work efficiency calculation system 1 includes a camera 30 , a work efficiency output device 100 connected to the camera 30 , and an administrator terminal 50 connected to the work efficiency output device 100 via the network 3 . In the present embodiment, the work efficiency output device 100 and the administrator terminal 50 are described as separate devices, but the administrator terminal 50 is omitted, and the functions of the administrator terminal 50, which will be described later, are used by the work efficiency output device 100. may be provided. Conversely, the work efficiency output device 100 may be omitted and the administrator terminal 50 may have the function of the work efficiency output device 100, which will be described later. connected to

　作業効率出力装置１００は、取得部１０１と、分類部１０２と、算出部１０３と、を備える。 (Functional configuration of work efficiency output device)
The work efficiency output device 100 includes an acquisition unit 101 , a classification unit 102 and a calculation unit 103 .
　取得部１０１は、作業者５ａ～５ｄの所定の作業を映した画像を取得する。詳細には、取得部１０１は、カメラ３０で撮影された作業者５ａ～５ｄの画像を取得する。画像は、動画であってもよいし、静止画であってもよい。また、カメラ３０とは、直接接続されていてもよいし、リモート接続であってもよい。 The acquisition unit 101 acquires images showing the predetermined work of the workers 5a to 5d. Specifically, the acquiring unit 101 acquires images of the workers 5a to 5d photographed by the camera 30. FIG. The image may be a moving image or a still image. Also, the camera 30 may be directly connected or remotely connected.
　分類部１０２は、前記取得した画像を解析して、出荷に向けて工程が進む本作業を映した画像であるか、又は、前記本作業に該当しない準備作業などの付随作業を映した画像であるかを分類する。詳細には、カメラ３０が撮影したフレーム毎に前記本作業と、前記付随作業を分類する。例えば、カメラ３０のフレームレートが６０fpsである場合、1秒間に６０枚の画像が撮影される。分類部１０２は、これら６０枚の画像を解析し、本作業と付随作業に分類してもよい。また、分類部１０２は、撮影したフレームの一部を判定してもよい。例えば、６０枚の画像のうち、１枚目と３１枚目のみ分類してもよい。このようにすれば分類処理の負荷を下げることができる。 The classification unit 102 analyzes the acquired image, and the image is an image showing the main work progressing toward shipping, or an image showing ancillary work such as preparatory work that does not correspond to the main work. Classify if there is Specifically, each frame captured by the camera 30 is classified into the main work and the auxiliary work. For example, if the camera 30 has a frame rate of 60 fps, 60 images are captured per second. The classification unit 102 may analyze these 60 images and classify them into main work and additional work. Also, the classification unit 102 may determine a part of the captured frame. For example, of 60 images, only the 1st and 31st images may be classified. In this way, the load of classification processing can be reduced.
　算出部１０３は、前記分類した各画像の撮影時間から、前記本作業の作業時間及び、前記付随作業の作業時間を、作業者毎に算出する。詳細には、１フレームあたりに予め撮影時間を設定しておき、本作業及び付随作業に分類されたフレーム数に積算して本作業の作業時間と付随作業の作業時間を算出する。 The calculation unit 103 calculates the working time of the main work and the working time of the incidental work for each worker from the shooting time of each classified image. Specifically, the photographing time is set in advance for each frame, and the number of frames classified into the main work and the incidental work is added to calculate the work time of the main work and the work time of the incidental work.
　本実施形態では、前記所定の作業とは、商品の梱包作業であって、前記分類部１０２が、商品の梱包作業における本作業を映した画像であるか、又は、前記本作業に該当しない付随作業を映した画像であるかを分類し、前記算出部１０３が、分類された商品の梱包作業の本作業（商品８ａ～８ｄをオリコン７ａ～７ｄへ入れる作業）の作業時間、及び付随作業の作業時間を、作業者毎に算出する。 In the present embodiment, the predetermined work is product packing work, and the classification unit 102 displays an image showing the actual product packing work, or an accompanying image that does not correspond to the actual product packing work. It classifies whether the image reflects work, and the calculation unit 103 calculates the work time of the main work of the classified product packing work (the work of putting the products 8a to 8d into the Oricons 7a to 7d) and the accompanying work. Work hours are calculated for each worker.
　また、本実施形態では、前記所定の作業は、複数の本作業（例えば、本作業１～本作業３）と、複数の付随作業（例えば、付随作業１～付随作業６）で構成され、前記算出部１０３は、作業時間の算出を、複数の本作業及び複数の付随作業の各々に対して行う。 Further, in the present embodiment, the predetermined work includes a plurality of main works (for example, main work 1 to main work 3) and a plurality of ancillary works (for example, ancillary work 1 to ancillary work 6). The calculation unit 103 calculates the work time for each of the plurality of main works and the plurality of accompanying works.
　また、本実施形態では、前記本作業の作業時間及び前記付随作業の作業時間に基づいて、前記作業者の作業効率を算出し、前記作業者の作業効率が所定の閾値以下の場合（例えば、５０％以下の場合など）に、管理者に通知する。 Further, in this embodiment, the work efficiency of the worker is calculated based on the work time of the main work and the work time of the incidental work, and when the work efficiency of the worker is equal to or less than a predetermined threshold value (for example, 50% or less), notify the administrator.
　また、本実施形態では、取得部１０１は、複数の作業者５ａ～５ｄの作業が同時に撮影された画像を取得し、当該画像から各作業者を抽出し、分類部１０２は、作業者５ａ～５ｄ毎に抽出された各画像を解析して、出荷に向けて工程が進む本作業を映した画像であるか、又は、前記本作業に該当しない付随作業を映した画像であるかを複数の作業者の画像に対して分類する。 Further, in the present embodiment, the acquiring unit 101 acquires images in which the work of a plurality of workers 5a to 5d is simultaneously captured, extracts each worker from the images, and classifies the workers 5a to 5d. Analyzing each image extracted every 5d, it is an image showing the main work in progress toward shipping, or an image showing ancillary work that does not correspond to the above-mentioned main work.

　次に、ステップＳ１８において、付随作業は指導中であるかどうかを判断する。ステップＳ１６において、作業効率が所定値以下ではないと判断した場合も、ステップＳ１８に進む。 Next, in step S18, it is determined whether or not the accompanying work is being instructed. Also when it is determined in step S16 that the working efficiency is not equal to or lower than the predetermined value, the process proceeds to step S18.
　付随作業は指導中であると判断した場合（ステップＳ１８でＹＥＳ）、作業効率出力装置１００は、指導中であることを管理者端末５０に通知する（ステップＳ１９）。 If it is determined that the accompanying work is under guidance (YES in step S18), the work efficiency output device 100 notifies the manager terminal 50 that guidance is underway (step S19).
　ステップＳ２０において、作業者毎に作業効率を時間帯で算出・表示する。ステップＳ１８で、付随作業は指導中ではないと判断した場合（ステップＳ１８でＮＯ）も、ステップＳ２０へ進む。 In step S20, the work efficiency is calculated and displayed for each worker by time period. If it is determined in step S18 that the accompanying work is not being instructed (NO in step S18), the process also proceeds to step S20.
