Abstract

In this invention, a loading time ts for a time-limit component tape feeder 5B (one feeder) for supplying components from a component supply reel 7 having an expiration date/time is set to or before the expiration date/time of a component supply reel 7 being loaded. In this manner, a component resupply operation can be executed by loading a component supply reel 7 before the expiration date/time of the component supply reel 7 being loaded passes. Furthermore, loading time ts (n+1) related to the time-limit component tape feeder 5B is overlapped with a loading-enabled period Tc of a different tape feeder 5C, and an identical loading time ts (n+1) is set to both feeders 5B, 5C. Therefore, loading operations for the tape feeders 5B, 5C can be executed together within a single component resupply. In this manner, the number of resupply operations can be reduced and, at the same time, the resupply operations can be executed at appropriate timings conforming to component expiration dates/times.

Description

部品補給管理装置、部品実装システムおよび部品補給管理方法Component supply management device, component mounting system, and component supply management method
　この発明は、基板に実装される部品を部品収納部材から供給するフィーダーに対する部品の補給を管理する技術に関する。 This invention relates to a technique for managing the replenishment of components to a feeder that supplies components mounted on a board from a component storage member.
　従来、基板に部品を実装することで部品実装基板を生産するために、例えば供給リール等の部品収納部材に収納された部品を供給するフィーダーが用いられている。このように部品収納部材からフィーダーにより部品を供給する構成では、特許文献１に示されるように、部品収納部材の部品を使い切ったフィーダーに対しては、部品供給部材を新たに装着して部品を補給する補給作業を実行する必要がある。 Conventionally, in order to produce a component mounting substrate by mounting components on a substrate, a feeder that supplies components stored in a component storage member such as a supply reel has been used. In the configuration in which components are supplied from the component storage member by the feeder in this way, as shown in Patent Document 1, a component supply member is newly attached to a feeder that has used up the components of the component storage member. It is necessary to carry out replenishment work to replenish.

　かかる補給作業はオペレーターによって実行される。これに対して、部品実装基板の生産には複数のフィーダーを用いることが一般的である。そのため、補給作業が頻発して、オペレーターの負担が大きくなる場合があった。したがって、オペレーターの負担軽減の観点から、一度の補給作業で多くの部品を補給して、補給作業の頻度を抑えたいという要望がある。 Such replenishment work is performed by the operator. On the other hand, it is common to use a plurality of feeders for the production of the component mounting board. As a result, replenishment work frequently occurs and the burden on the operator may increase. Therefore, from the viewpoint of reducing the burden on the operator, there is a demand for supplying a large number of parts in a single replenishment operation and reducing the frequency of the replenishment operation.
　ただし、部品実装基板の生産に用いられる部品には、特許文献２に示されるように、使用期限を有する部品がある。したがって、補給作業は、部品の使用期限に応じた適切なタイミングで行う必要がある。 However, as used in the production of a component mounting board, there is a component having an expiration date as disclosed in Patent Document 2. Accordingly, the replenishment work needs to be performed at an appropriate timing according to the expiration date of the parts.
　この発明は上記課題に鑑みなされたものであり、その頻度を抑制しつつも、部品の使用期限に応じた適切なタイミングで、補給作業を実行可能とする技術の提供を目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of performing a replenishment operation at an appropriate timing according to the expiration date of a component while suppressing the frequency.
　本発明に係る部品補給管理装置は、装着された複数の部品収納部材を順番に用いて当該部品収納部材から部品を供給するフィーダーを複数用いて部品を基板に実装することで部品実装基板を生産する生産計画を取得する取得部と、複数の部品収納部材のうち一の部品収納部材の部品が切れてから、複数の部品収納部材に残存する部品の総数である残存部品総数が所定個数まで減少する装着可能期間を生産計画に基づき予測した結果に応じて、部品収納部材をフィーダーに装着する装着作業の実行タイミングを示す装着時間を設定する設定部とを備え、設定部は、複数のフィーダーのうち、使用期限を有する部品収納部材の部品を供給する一のフィーダーに対する装着時間を、装着中の部品収納部材の使用期限以前に設定するとともに別のフィーダーの装着可能期間に重複させ、一のフィーダーおよび別のフィーダーそれぞれに対して同一の装着時間を設定する。 The component replenishment management apparatus according to the present invention produces a component mounting board by mounting a component on a substrate using a plurality of feeders that supply components from the component storing member using a plurality of mounted component storing members in order. The number of remaining parts, which is the total number of parts remaining in a plurality of component storage members, has been reduced to a predetermined number after a part of one of the component storage members has been cut and an acquisition unit that acquires a production plan A setting unit configured to set a mounting time indicating the execution timing of a mounting operation for mounting the component storage member on the feeder according to a result of predicting the mounting possible period based on the production plan, and the setting unit includes a plurality of feeders. Of these, the mounting time for one feeder that supplies parts for the component storage member with the expiration date is set before the expiration date of the component storage member being installed, Be duplicated on wearable period leader, sets the same wear time for each one feeder and another feeder.
　本発明に係る部品補給管理方法は、装着された複数の部品収納部材を順番に用いて当該部品収納部材から部品を供給するフィーダーを複数用いて部品を基板に実装することで部品実装基板を生産する生産計画を取得する工程と、複数の部品収納部材のうち一の部品収納部材の部品が切れてから、複数の部品収納部材に残存する部品の総数である残存部品総数が所定個数まで減少する装着可能期間を生産計画に基づき予測した結果に応じて、部品収納部材をフィーダーに装着する装着作業の実行タイミングを示す装着時間を設定する工程とを備え、装着時間を設定する工程では、複数のフィーダーのうち、使用期限を有する部品収納部材の部品を供給する一のフィーダーに対する装着時間を、装着中の部品収納部材の使用期限以前に設定するとともに別のフィーダーの装着可能期間に重複させ、一のフィーダーおよび別のフィーダーそれぞれに対して同一の装着時間を設定する。 The component replenishment management method according to the present invention produces a component mounting board by mounting a component on a substrate using a plurality of feeders that supply components from the component storing member using a plurality of mounted component storing members in order. The number of remaining parts, which is the total number of parts remaining in the plurality of component storage members, is reduced to a predetermined number after the process of obtaining the production plan to be performed and the part of one of the plurality of component storage members is cut. A step of setting a mounting time indicating an execution timing of a mounting operation for mounting the component storage member on the feeder according to a result of predicting the mountable period based on the production plan. Of the feeders, set the mounting time for one feeder that supplies the components of the component storage member having the expiration date before the expiration date of the component storage member being mounted. Both are overlapped in mounted period of another feeder, setting the same wear time for each one feeder and another feeder.
　このように構成された本発明（部品補給管理装置、部品補給管理方法）では、使用期限を有する部品収納部材の部品を供給する一のフィーダーに対する装着時間が、装着中の部品収納部材の使用期限以前に設定される。これによって、装着中の部品収納部材の使用期限が経過する前に、部品収納部材を装着して部品の補給作業を実行できる。また、別のフィーダーに対する装着時間が、当該別のフィーダーの装着可能期間に重複するように設定される。これによって、別のフィーダーに装着中の複数の部品収納部材のうち、一の部品収納部材が部品切れを起こしてから、複数の部品収納部材の残存部品総数が所定個数に減るまでに、別のフィーダーに対して装着作業が実行できる。したがって、別のフィーダーに装着された全部品収納部材が部品切れを起こす前に、当該別のフィーダーに対する装着作業を実行することができる。しかも、当該一のフィーダーに対する装着時間を別のフィーダーの装着可能期間に重複させて、一のフィーダーおよび別のフィーダーそれぞれに対して同一の装着時間が設定される。したがって、これらのフィーダーに対する装着作業を１回の部品補給でまとめて実行することができる。こうして、本発明では、その頻度を抑制しつつも、部品の使用期限に応じた適切なタイミングで、補給作業を実行することが可能となっている。 In the present invention (component supply management device, component supply management method) configured as described above, the installation time for one feeder that supplies the components of the component storage member having the expiration date is the expiration date of the component storage member being installed. Set before. Thereby, before the expiration date of the component storage member being mounted elapses, the component storage member can be mounted and the component supply operation can be executed. In addition, the mounting time for another feeder is set to overlap with the period in which the other feeder can be mounted. As a result, among a plurality of component storage members mounted on another feeder, after one component storage member has run out of parts, the remaining number of remaining parts of the plurality of component storage members is reduced to a predetermined number. Installation work can be performed on the feeder. Therefore, the mounting operation for the another feeder can be executed before all the component storage members mounted on the other feeder run out of components. In addition, the same mounting time is set for each of one feeder and another feeder by overlapping the mounting time for the one feeder with the period in which another feeder can be mounted. Therefore, it is possible to collectively perform the mounting operation for these feeders with one component replenishment. Thus, according to the present invention, it is possible to execute the replenishment work at an appropriate timing according to the expiration date of the parts while suppressing the frequency.
　なお、本明細書において、「使用期限以前」とは、使用期限より前および使用期限と同時を含む概念である。 In addition, in this specification, “before the expiration date” is a concept including before the expiration date and simultaneously with the expiration date.
　また、設定部は、一のフィーダーに対する装着時間を、当該一のフィーダーの装着可能期間と、別のフィーダーの装着可能期間とに重複するように設定するように部品補給管理装置を構成しても良い。かかる構成では、一のフィーダーに装着中の複数の部品収納部材のうち、一の部品収納部材が部品切れを起こしてから、複数の部品収納部材の残存部品総数が所定個数に減るまでに、一のフィーダーに対して装着作業が実行できる。したがって、一のフィーダーに装着された全部品収納部材が部品切れを起こす前に、当該一のフィーダーに対する装着作業を実行することができる。 In addition, the setting unit may configure the component supply management device to set the mounting time for one feeder so as to overlap the mounting period for the one feeder and the mounting period for another feeder. good. In such a configuration, one component storage member among a plurality of component storage members being mounted on one feeder has run out until the total number of remaining components of the plurality of component storage members is reduced to a predetermined number. Installation work can be performed on the feeder. Therefore, the mounting operation for the one feeder can be executed before all the component storage members mounted on the one feeder run out of parts.
　また、設定部は、一のフィーダーの装着可能期間と重複する装着可能期間を有する別のフィーダーとして２個の別のフィーダーが少なくとも存在し、２個の別のフィーダーそれぞれの装着可能期間が重複しない場合、２個の別のフィーダーそれぞれの装着可能期間のうち遅い方の装着可能期間に重複するように、一のフィーダーに対する装着時間を設定するように、部品補給管理装置を構成しても良い。かかる構成では、一のフィーダーの装着可能期間が経過しない範囲で、当該一のフィーダーに対する装着時間をできるだけ遅く設定することができる。これによって、この装着時間に応じたタイミングで装着される部品収納部材の使用開始時間を遅らせることができ、その結果、当該部品収納部材の使用期限を遅らせることができる。 In addition, the setting unit has at least two different feeders as another feeder having a mounting period that overlaps the mounting period of one feeder, and the mounting period of each of the two other feeders does not overlap. In this case, the parts replenishment management device may be configured to set the mounting time for one feeder so as to overlap the later mounting possible period of the two other feeders. In such a configuration, it is possible to set the mounting time for the one feeder as late as possible within the range in which the one feeder can be mounted. Accordingly, it is possible to delay the use start time of the component storage member to be mounted at a timing according to the mounting time, and as a result, it is possible to delay the expiration date of the component storage member.
　また、設定部は、一のフィーダーの装着可能期間の前に一のフィーダーに装着中の部品収納部材の使用期限が経過すると予測すると、それぞれの装着可能期間が使用期限以前に互いに重複する複数の別のフィーダーそれぞれの装着可能期間に重複させつつ、一のフィーダーに対する装着時間を使用期限以前に設定するように、部品補給管理装置を構成しても良い。これによって、一のフィーダーに装着中の部品収納部材の使用期限の経過前に当該一のフィーダーに対する装着作業を確実に実行できるとともに、当該一のフィーダーに対する装着作業を、複数の別のフィーダーに対する装着作業とまとめて、１回の補給作業で実行することが可能となる。 In addition, when the setting unit predicts that the expiration date of the component storage member being attached to one feeder will elapse before the one feeder installation period, each setting period may overlap with each other before the expiration date. The parts replenishment management device may be configured to set the mounting time for one feeder before the expiration date while overlapping each other feeder's mountable period. As a result, the mounting operation for the one feeder can be reliably executed before the expiration date of the component storage member being mounted on the one feeder, and the mounting operation for the one feeder can be performed on a plurality of other feeders. Together with the work, it can be executed in one replenishment work.
　また、設定部は、複数のフィーダーのうちから、一のフィーダーに装着中の部品収納部材の使用期限に装着可能期間が重複する別のフィーダーを予測し、一のフィーダーおよび別のフィーダーそれぞれに対する同一の装着時間として使用期限を設定するように、部品補給管理装置を構成しても良い。かかる構成では、一のフィーダーに装着中の部品収納部材の使用期限が経過するタイミングで、当該一のフィーダーへの装着作業と別のフィーダーへの装着作業とを、１回の補給作業でまとめて実行できる。 In addition, the setting unit predicts another feeder having a period that can be mounted at the expiration date of the component storage member being mounted on one feeder from the plurality of feeders, and the same for each of the one feeder and another feeder. The parts replenishment management device may be configured so that the expiration date is set as the mounting time of the component. In such a configuration, at the timing when the expiration date of the component storage member being mounted on one feeder elapses, the mounting operation on the one feeder and the mounting operation on another feeder are combined in one replenishment operation. Can be executed.
　また、設定部は、一のフィーダーに装着可能な部品収納部材として、使用期限が互いに異なる複数の対象収納部材が存在する場合、複数の対象収納部材それぞれの使用期限と生産計画とに基づき、一のフィーダーに装着する対象収納部材を選択するように、部品補給管理装置を構成しても良い。かかる構成では、生産計画に対して適切な使用期限を有する部品収納部材を一のフィーダーに装着することができる。 In addition, when there are a plurality of target storage members having different expiration dates as the component storage members that can be attached to one feeder, the setting unit determines whether one of the plurality of target storage members is based on the expiration date and the production plan. The parts supply management device may be configured to select a target storage member to be mounted on the feeder. In such a configuration, it is possible to mount a component storage member having an appropriate expiration date for the production plan in one feeder.
　また、設定部は、装着時間で一のフィーダーに装着したと仮定した場合に、生産計画の実行に伴って部品切れが発生する予想時間より使用期限が後となる対象収納部材のうち、使用期限が最も早い対象収納部材を、一のフィーダーに装着すると決定するように、部品補給管理装置を構成しても良い。かかる構成では、一のフィーダーに装着中の部品収納部材の使用期限が生産計画の実行途中に切れるのを抑制しつつ、使用期限の短い部品収納部材を有効活用することができる。 In addition, when the setting unit assumes that the first feeder is installed in the installation time, the expiration date of the target storage member whose expiration date is later than the expected time when the parts run out due to the production plan is executed. The parts supply management device may be configured so that the earliest target storage member is determined to be attached to one feeder. In such a configuration, it is possible to effectively utilize a component storage member with a short expiration date while suppressing the expiration date of the component storage member being attached to one feeder from being cut off during the execution of the production plan.
　本発明に係る部品実装システムは、装着された複数の部品収納部材を順番に用いて当該部品収納部材から部品を供給するフィーダーを複数用いて部品を基板に実装することで部品実装基板を生産する生産計画を実行する部品実装機と、上記の部品補給管理装置とを備える。したがって、その頻度を抑制しつつも、部品の使用期限に応じた適切なタイミングで、補給作業を実行することが可能となっている。 The component mounting system according to the present invention produces a component mounting board by mounting a component on a substrate using a plurality of feeders that supply components from the component storing member using a plurality of mounted component storing members in order. A component mounter that executes a production plan and the component supply management device described above are provided. Therefore, it is possible to execute the replenishment work at an appropriate timing according to the expiration date of the parts while suppressing the frequency.
　本発明によれば、その頻度を抑制しつつも、部品の使用期限に応じた適切なタイミングで、補給作業を実行することが可能となる。 According to the present invention, it is possible to perform the replenishment work at an appropriate timing according to the expiration date of the parts while suppressing the frequency.

　図１は本発明に係る部品供給管理装置による管理対象の一例である部品実装機を模式的に示す平面図である。同図では、鉛直方向に平行なＺ方向、それぞれ水平方向に平行なＸ方向およびＹ方向からなるＸＹＺ直交座標を示す。この部品実装機１は、基台１１の上に設けられた一対のコンベア１２、１２を備える。そして、部品実装機１は、コンベア１２によりＸ方向（基板搬送方向）の上流側から作業位置（図１の基板Ｂの位置）に搬入した基板Ｂに対して部品を実装し、部品実装を完了した基板Ｂをコンベア１２により作業位置からＸ方向の下流側へ搬出する。 FIG. 1 is a plan view schematically showing a component mounter which is an example of a management target by a component supply management device according to the present invention. In the figure, XYZ orthogonal coordinates composed of a Z direction parallel to the vertical direction and an X direction and a Y direction parallel to the horizontal direction are shown. The component mounting machine 1 includes a pair of conveyors 12 and 12 provided on a base 11. Then, the component mounting machine 1 mounts the components on the board B carried into the work position (position of the board B in FIG. 1) from the upstream side in the X direction (board transport direction) by the conveyor 12, and completes the component mounting. The substrate B is carried out from the work position to the downstream side in the X direction by the conveyor 12.
　部品実装機１では、Ｙ方向に延びる一対のＹ軸レール２１、２１と、Ｙ方向に延びるＹ軸ボールネジ２２と、Ｙ軸ボールネジ２２を回転駆動するＹ軸モーターＭｙとが設けられ、ヘッド支持部材２３が一対のＹ軸レール２１、２１にＹ方向に移動可能に支持された状態でＹ軸ボールネジ２２のナットに固定されている。ヘッド支持部材２３には、Ｘ方向に延びるＸ軸ボールネジ２４と、Ｘ軸ボールネジ２４を回転駆動するＸ軸モーターＭｘとが取り付けられており、ヘッドユニット３がヘッド支持部材２３にＸ方向に移動可能に支持された状態でＸ軸ボールネジ２４のナットに固定されている。したがって、Ｙ軸モーターＭｙによりＹ軸ボールネジ２２を回転させてヘッドユニット３をＹ方向に移動させ、あるいはＸ軸モーターＭｘによりＸ軸ボールネジ２４を回転させてヘッドユニット３をＸ方向に移動させることができる。 The component mounter 1 is provided with a pair of Y- axis rails 21, 21 extending in the Y direction, a Y-axis ball screw 22 extending in the Y direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 22, and a head support member 23 is fixed to the nut of the Y-axis ball screw 22 while being supported by the pair of Y- axis rails 21 and 21 so as to be movable in the Y direction. An X-axis ball screw 24 extending in the X direction and an X-axis motor Mx that rotationally drives the X-axis ball screw 24 are attached to the head support member 23, and the head unit 3 can move to the head support member 23 in the X direction. The nut is fixed to the nut of the X-axis ball screw 24 while being supported by the nut. Therefore, the Y-axis ball screw 22 is rotated by the Y-axis motor My to move the head unit 3 in the Y direction, or the X-axis ball screw 24 is rotated by the X-axis motor Mx to move the head unit 3 in the X direction. it can.
　一対のコンベア１２、１２のＹ方向の両側それぞれでは２つの部品供給部２５がＸ方向に並んでおり、各部品供給部２５に対してはフィーダー取付台車４が着脱可能に取り付けられている。このフィーダー取付台車４には、Ｘ方向に並ぶ複数のテープフィーダー５と、Ｘ方向に並ぶ複数のリールホルダー６とが着脱可能に装着されており、１個のテープフィーダー５と１個のリールホルダー６とが互いに対応付けられてＹ方向に並ぶ。 The two component supply units 25 are arranged in the X direction on each side of the pair of conveyors 12 and 12 in the Y direction, and the feeder mounting cart 4 is detachably attached to each component supply unit 25. A plurality of tape feeders 5 arranged in the X direction and a plurality of reel holders 6 arranged in the X direction are detachably mounted on the feeder mounting carriage 4, and one tape feeder 5 and one reel holder are mounted. 6 are associated with each other and arranged in the Y direction.
　各リールホルダー６に保持される部品供給リール７は、集積回路、トランジスター、コンデンサ等の小片状の部品（チップ電子部品）を所定間隔おきに収納した部品供給テープＴＰを有する。この部品供給テープＴＰは、等ピッチで一列に配列された複数のポケットのそれぞれに部品を収納するキャリアテープと、キャリアテープに貼り付けられて部品をポケット内の部品を覆うカバーテープとを有する。キャリアテープＴＰの一辺側には、その縁に沿って一定間隔で配列された複数の係合孔が貫通している。後述するように、各テープフィーダー５に対しては２本のキャリアテープＴＰを取付可能であり、これに対応して、各リールホルダー６はＹ方向に並ぶ２個の部品供給リール７を保持する。そして、各テープフィーダー５は、Ｙ方向に隣り合うリールホルダー６内の部品供給リール７から引き出したキャリアテープＴＰをヘッドユニット３側に間欠的に送り出すことで、キャリアテープＴＰ内の部品を所定の部品供給位置５０に供給する（部品供給動作）。 The component supply reel 7 held by each reel holder 6 has a component supply tape TP in which small pieces (chip electronic components) such as an integrated circuit, a transistor, and a capacitor are stored at predetermined intervals. The component supply tape TP includes a carrier tape that stores components in each of a plurality of pockets arranged in a line at an equal pitch, and a cover tape that is attached to the carrier tape and covers the components in the pockets. On one side of the carrier tape TP, a plurality of engagement holes arranged at regular intervals pass through the edge. As will be described later, two carrier tapes TP can be attached to each tape feeder 5, and correspondingly, each reel holder 6 holds two component supply reels 7 arranged in the Y direction. . Then, each tape feeder 5 intermittently feeds the carrier tape TP pulled out from the component supply reel 7 in the reel holder 6 adjacent in the Y direction to the head unit 3 side, so that the components in the carrier tape TP are predetermined. Supply to the component supply position 50 (component supply operation).
　ヘッドユニット３は、Ｘ方向に並ぶ複数（４本）の実装ヘッド３１を有する。各実装ヘッド３１はＺ方向（鉛直方向）に延びた長尺形状を有し、その下端に係脱可能に取り付けられたノズルによって部品を吸着・保持することができる。つまり、実装ヘッド３１はテープフィーダー５の上方へ移動して、テープフィーダー５により供給された部品を吸着する。続いて、実装ヘッド３１は作業位置の基板Ｂの上方に移動して部品の吸着を解除することで、基板Ｂに部品を実装する。こうして、実装ヘッド３１は、テープフィーダー５により部品供給位置５０に供給された部品をキャリアテープＴＰから取り出して基板Ｂに実装する部品実装を実行する。 The head unit 3 has a plurality (four) of mounting heads 31 arranged in the X direction. Each mounting head 31 has a long shape extending in the Z direction (vertical direction), and can suck and hold components by a nozzle that is detachably attached to the lower end thereof. That is, the mounting head 31 moves above the tape feeder 5 and sucks the components supplied by the tape feeder 5. Subsequently, the mounting head 31 mounts the component on the board B by moving above the board B at the work position and releasing the suction of the component. In this way, the mounting head 31 executes component mounting in which the component supplied to the component supply position 50 by the tape feeder 5 is taken out from the carrier tape TP and mounted on the substrate B.
　図２はテープフィーダーの構成および動作の一例を模式的に示す側面図である。同図および以下の図面では、テープフィーダー５がキャリアテープＴＰを送り出すフィード方向Ｄｆ（Ｙ方向に平行）を適宜示すとともに、フィード方向Ｄｆの矢印側をフィード方向Ｄｆの「前」と、フィード方向Ｄｆの矢印の反対側をフィード方向Ｄｆの「後ろ」と取り扱う。また、テープフィーダー５に取付可能な２本のキャリアテープＴＰを区別するために、同図および以下の図では、キャリアテープに対して異なる符号ＴＰ１、ＴＰ２を適宜用いる。 FIG. 2 is a side view schematically showing an example of the configuration and operation of the tape feeder. In this figure and the following drawings, the feed direction Df (parallel to the Y direction) in which the tape feeder 5 feeds out the carrier tape TP is appropriately shown, and the arrow side of the feed direction Df is set to “front” of the feed direction Df and the feed direction Df. The other side of the arrow is treated as “rear” in the feed direction Df. Further, in order to distinguish between the two carrier tapes TP that can be attached to the tape feeder 5, in the figure and the following figures, different symbols TP1 and TP2 are appropriately used for the carrier tape.
　テープフィーダー５は、機械的構成であるフィーダー本体５１と、フィーダー本体５１を駆動するモーターＭｆ、Ｍｂとを備える。フィーダー本体５１は、Ｘ方向に薄くてフィード方向Ｄｆに長尺な偏平形状のケース５２を有する。ケース５２のフィード方向Ｄｆの後端では、Ｚ方向に延設されたテープ挿入口５３ａ（破線で示す）が開口し、ケース５２のフィード方向Ｄｆの前方の上面に上述の部品供給位置５０が設けられている。フィーダー本体５１内ではテープ挿入口５３ａから部品供給位置５０へ至るテープ搬送路５３ｂが設けられている。このフィーダー本体５１は、テープ挿入口５３ａからテープ搬送路５３ｂに挿入されたキャリアテープＴＰを、モーターＭｆ、Ｍｂの駆動力を受けてフィード方向Ｄｆに送り出すことで、部品供給位置５０に部品を供給する。 The tape feeder 5 includes a feeder main body 51 that is a mechanical configuration, and motors Mf and Mb that drive the feeder main body 51. The feeder body 51 has a flat case 52 that is thin in the X direction and long in the feed direction Df. At the rear end of the feed direction Df of the case 52, a tape insertion opening 53a (shown by a broken line) extending in the Z direction opens, and the above-described component supply position 50 is provided on the upper surface of the case 52 in the feed direction Df. It has been. In the feeder main body 51, a tape transport path 53b extending from the tape insertion port 53a to the component supply position 50 is provided. The feeder main body 51 supplies the component to the component supply position 50 by sending the carrier tape TP inserted into the tape transport path 53b from the tape insertion port 53a in the feed direction Df under the driving force of the motors Mf and Mb. To do.
　具体的には、フィーダー本体５１は、テープ搬送路５３ｂの上方でテープ挿入口５３ａに隣接して配置されたスプロケット５４と、モーターＭｂの駆動力をスプロケット５４に伝達するギヤ５５とをケース５２内に有し、スプロケット５４はモーターＭｂが発生する駆動力を受けて回転する。さらに、フィーダー本体５１は、ケース５２に対して着脱可能に取り付けられたテープ支持部材５６を有する。このテープ支持部材５６はスプロケット５４に下方から対向し、スプロケット５４との間にキャリアテープＴＰを挟むことで、キャリアテープＴＰをスプロケット５４に係合させる。これによって、スプロケット５４はキャリアテープＴＰに係合しつつ回転することで、キャリアテープＴＰをフィード方向Ｄｆに送り出すことができる。また、フィーダー本体５１は、その前端部分に配置されて下方からテープ搬送路５３ｂに隣接するスプロケット５７と、モーターＭｆの駆動力をスプロケット５７に伝達するギヤ５８とをケース５２内に有し、スプロケット５７はモーターＭｆが発生する駆動力を受けて回転する。したがって、スプロケット５７は、キャリアテープＴＰに係合しつつ間欠的に回転することで、キャリアテープＴＰをフィード方向Ｄｆに間欠的に搬送することができる。 Specifically, the feeder main body 51 includes a sprocket 54 disposed adjacent to the tape insertion port 53a above the tape conveyance path 53b and a gear 55 that transmits the driving force of the motor Mb to the sprocket 54. The sprocket 54 rotates upon receiving a driving force generated by the motor Mb. Furthermore, the feeder main body 51 has a tape support member 56 that is detachably attached to the case 52. The tape support member 56 faces the sprocket 54 from below, and the carrier tape TP is engaged with the sprocket 54 by sandwiching the carrier tape TP between the tape support member 56 and the sprocket 54. Thus, the sprocket 54 rotates while engaging with the carrier tape TP, so that the carrier tape TP can be sent out in the feed direction Df. The feeder main body 51 has a sprocket 57 disposed at the front end portion thereof and adjacent to the tape transport path 53b from below and a gear 58 for transmitting the driving force of the motor Mf to the sprocket 57 in the case 52. 57 rotates by receiving the driving force generated by the motor Mf. Therefore, the sprocket 57 can intermittently convey the carrier tape TP in the feed direction Df by rotating intermittently while engaging the carrier tape TP.
　また、フィーダー本体５１は、部品供給位置５０のフィード方向Ｄｆの上流側で部品供給テープＴＰに接触するカッターを有する。このカッターは、フィード方向Ｄｆに間欠搬送される部品供給テープＴＰのカバーテープを中央で切り裂いて両側に捲くることで、部品供給位置５０に供給された部品を露出させる。このように部品を露出するための構成は、例えば特開２０１５－０５３３２０号公報に記載のそれと同様である。 Further, the feeder main body 51 has a cutter that contacts the component supply tape TP on the upstream side of the feed direction Df of the component supply position 50. This cutter exposes the component supplied to the component supply position 50 by tearing the cover tape of the component supply tape TP, which is intermittently conveyed in the feed direction Df, at the center and scooping it to both sides. The configuration for exposing the components in this way is the same as that described in, for example, Japanese Patent Application Laid-Open No. 2015-053320.
　ステップＳ１１は、実装ヘッド３１による部品実装にテープフィーダー５が使用されている状態に対応する。つまり、フィーダー本体５１には、テープ搬送路５３ｂに沿ってキャリアテープＴＰ１が挿入されており、スプロケット５７はキャリアテープＴＰ１をフィード方向Ｄｆへ間欠搬送することで、基板Ｂに実装される部品を部品供給位置５０に供給する。また、ステップＳ１１では、キャリアテープＴＰ１の次に部品実装に使用されるキャリアテープＴＰ２の先端が、スプロケット５４とテープ支持部材５６との間に取り付けられている。こうして、次に使用されるキャリアテープＴＰ２がフィーダー本体５１の後端部分で待機する。 Step S11 corresponds to a state in which the tape feeder 5 is used for component mounting by the mounting head 31. That is, the carrier tape TP1 is inserted into the feeder main body 51 along the tape transport path 53b, and the sprocket 57 intermittently transports the carrier tape TP1 in the feed direction Df, so that the component mounted on the board B is a component. Supply to supply position 50. In step S <b> 11, the tip of the carrier tape TP <b> 2 used for component mounting next to the carrier tape TP <b> 1 is attached between the sprocket 54 and the tape support member 56. Thus, the carrier tape TP2 to be used next stands by at the rear end portion of the feeder main body 51.
　ステップＳ１２に示すように、キャリアテープＴＰ１内の部品が使い切られて、テープフィーダー５がキャリアテープＴＰ１を排出すると、ステップＳ１３に示すローディングが実行される。具体的には、スプロケット５４が回転を開始してキャリアテープＴＰ２を部品供給位置５０へ向けてフィード方向Ｄｆに送り出し、キャリアテープＴＰ２の先端をスプロケット５７に係合させる。続いて、ステップＳ１４において、オペレーターがテープ支持部材５６をケース５２から取り外す作業を実行すると、キャリアテープＴＰ２がスプロケット５４から外れてテープ搬送路５３ｂに落下する。これによって、スプロケット５７はキャリアテープＴＰ２をフィード方向Ｄｆへ間欠搬送して、キャリアテープＴＰ２内の部品を部品供給位置５０に供給することができる。ちなみに、オペレーターはステップＳ１４の後、テープ支持部材５６を再びケース５２に取り付けることで、キャリアテープＴＰ２の次に部品実装に使用されるキャリアテープＴＰをスプロケット５４とテープ支持部材５６との間に取り付けて待機させることができる。 As shown in step S12, when the parts in the carrier tape TP1 are used up and the tape feeder 5 ejects the carrier tape TP1, loading shown in step S13 is executed. Specifically, the sprocket 54 starts rotating and feeds the carrier tape TP2 toward the component supply position 50 in the feed direction Df, and the tip of the carrier tape TP2 is engaged with the sprocket 57. Subsequently, when the operator performs an operation of removing the tape support member 56 from the case 52 in step S14, the carrier tape TP2 is detached from the sprocket 54 and falls to the tape transport path 53b. Thus, the sprocket 57 can intermittently convey the carrier tape TP2 in the feed direction Df and supply the components in the carrier tape TP2 to the component supply position 50. Incidentally, after step S14, the operator attaches the tape support member 56 to the case 52 again, thereby attaching the carrier tape TP used for component mounting next to the carrier tape TP2 between the sprocket 54 and the tape support member 56. Can wait.
　このようなテープフィーダー５を用いた部品実装機１では、使用中のキャリアテープＴＰはテープ搬送路５３ｂに沿ってフィーダー本体５１に挿入される一方、次に使用されるキャリアテープＴＰは、テープ搬送路５３ｂの上方で待機する。そして、キャリアテープＴＰが使い切られる度にステップＳ１２～Ｓ１４を行うことで、待機していたキャリアテープＴＰをテープ搬送路５３ｂに沿ってフィーダー本体５１に挿入して、次に使用することができる。 In the component mounting machine 1 using such a tape feeder 5, the carrier tape TP being used is inserted into the feeder main body 51 along the tape conveyance path 53b, while the carrier tape TP to be used next is the tape conveyance. Waits above the path 53b. By performing steps S12 to S14 each time the carrier tape TP is used up, the waiting carrier tape TP can be inserted into the feeder main body 51 along the tape transport path 53b and used next.
　図３は部品供給リールとこれを保持するリールホルダーの一例を模式的に示す図である。図３では、リールホルダー６を透かして、部品供給リール７を示している。部品供給リール７は、軸心７１と、軸心７１を両側から挟む２枚の側板７２とを有し、軸心７１に巻き付けられた部品供給テープＴＰを側板７２により両側から支える。また、リール７は、それぞれバーコードで構成されたリールＩＤ７３および部品ＩＤ７４を側板７２に有する。リールＩＤ７３はユニークであり、それが付された部品供給リール７を個別に識別するのに用いることができる。部品ＩＤ７４は、それが付された部品供給リール７の部品供給テープＴＰに収納される部品に関する情報（部品の種類、個数等）を示す。また、テープフィーダー５によって供給される部品の中には、使用期限を有する部品が存在する。したがって、使用期限を有する部品を収容する部品供給リール７の部品ＩＤ７４は、当該使用期限を部品に関する情報の１つとして示す。この使用期限は、部品供給リール７を開封した開封時間から開始し、開封時間から所定期間が経過すると終了する。なお、リールＩＤ７３および部品ＩＤ７４を別々のバーコードで構成する必要は必ずしもなく、これらを１つのバーコードで構成しても良い。 FIG. 3 is a diagram schematically showing an example of a component supply reel and a reel holder that holds the component supply reel. In FIG. 3, the component supply reel 7 is shown through the reel holder 6. The component supply reel 7 has an axis 71 and two side plates 72 sandwiching the axis 71 from both sides, and supports the component supply tape TP wound around the axis 71 from both sides by the side plate 72. The reel 7 has a reel ID 73 and a component ID 74 each formed of a barcode on the side plate 72. The reel ID 73 is unique and can be used to individually identify the component supply reel 7 to which the reel ID 73 is attached. The part ID 74 indicates information (parts type, number, etc.) regarding the parts stored in the part supply tape TP of the part supply reel 7 to which the part ID 74 is attached. Among the parts supplied by the tape feeder 5, there are parts having a use expiration date. Therefore, the component ID 74 of the component supply reel 7 that accommodates a component having an expiration date indicates the expiration date as one piece of information regarding the component. This expiration date starts from the opening time when the component supply reel 7 is opened, and ends when a predetermined period elapses from the opening time. Note that the reel ID 73 and the component ID 74 are not necessarily configured by separate barcodes, and may be configured by one barcode.
　リールホルダー６は、使用位置Ｌｕと、使用位置Ｌｕよりフィード方向Ｄｆの後方の待機位置Ｌｗとのそれぞれで部品供給リール７を保持することができる。そして、使用位置Ｌｕに保持される部品供給リール７の部品供給テープＴＰがテープフィーダー５にローディングされて部品実装での部品供給に使用される一方、待機位置Ｌｗに保持される部品供給リール７の部品供給テープＴＰがテープフィーダー５のスプロケット５４とテープ支持部材５６との間に取り付けられる。このように、１台のテープフィーダー５に対しては、２個の部品供給リール７を装着することができる。なお、部品供給リール７をテープフィーダー５に装着するとは、リールホルダー６に配置した部品供給リール７から引き出した部品供給テープＴＰの先端をテープフィーダー５に装着することを示す。 The reel holder 6 can hold the component supply reel 7 at each of the use position Lu and the standby position Lw behind the use direction Lu in the feed direction Df. The component supply tape TP of the component supply reel 7 held at the use position Lu is loaded on the tape feeder 5 and used for component supply in component mounting, while the component supply reel 7 held at the standby position Lw is used. The component supply tape TP is attached between the sprocket 54 of the tape feeder 5 and the tape support member 56. In this manner, two component supply reels 7 can be mounted on one tape feeder 5. The mounting of the component supply reel 7 on the tape feeder 5 indicates that the tip of the component supply tape TP pulled out from the component supply reel 7 arranged on the reel holder 6 is mounted on the tape feeder 5.
　かかる構成では、テープフィーダー５に装着された２個の部品供給リール７のうち、使用位置Ｌｕに配置された部品供給リール７の部品供給テープＴＰの部品が使い切られると、待機位置Ｌｗに配置された部品供給リール７の部品供給テープＴＰがローディングされて、部品実装に使用される。こうして２個の部品供給リール７のうち一の部品供給リール７が使い切られた後は、オペレーターは、部品保管庫８１から供給された別の部品供給リール７をテープフィーダー５に装着して、待機させておくことができる。具体的には、オペレーターは、
・部品が切れた部品供給リール７を使用位置Ｌｕから取り除く
・部品実装で使用される部品供給リール７を待機位置Ｌｗから使用位置Ｌｕへ移動させる
・別の部品供給リール７を待機位置Ｌｗに配置する
・別の部品供給リール７から引き出した部品供給テープＴＰの先端をスプロケット５４とテープ支持部材５６との間に装着する
といった手順を順番に実行することで、別の部品供給リール７をテープフィーダー５に装着できる（装着作業）。 In such a configuration, when the components of the component supply tape TP of the component supply reel 7 disposed at the use position Lu are used up out of the two component supply reels 7 mounted on the tape feeder 5, they are disposed at the standby position Lw. The component supply tape TP of the component supply reel 7 is loaded and used for component mounting. After one of the two component supply reels 7 is used up in this way, the operator puts another component supply reel 7 supplied from the component storage 81 into the tape feeder 5 and waits. I can leave it to you. Specifically, the operator
-Remove the component supply reel 7 from which the component has been cut from the use position Lu-Move the component supply reel 7 used for component mounting from the standby position Lw to the use position Lu-Place another component supply reel 7 at the standby position Lw The other component supply reel 7 is attached to the tape feeder by sequentially executing the procedure of mounting the tip of the component supply tape TP pulled out from the other component supply reel 7 between the sprocket 54 and the tape support member 56. 5 (mounting work).
　図４は本発明に係る部品実装システムの一例を示すブロック図である。この部品実装システム１００は、部品実装機１と、部品実装機１で使用される部品供給リール７を保管する部品保管庫８１と、部品実装機１での部品実装を管理する生産計画管理装置８２と、部品実装機１への部品の補給を管理する部品補給管理装置９とを備える。 FIG. 4 is a block diagram showing an example of a component mounting system according to the present invention. The component mounting system 100 includes a component mounting machine 1, a component storage 81 for storing a component supply reel 7 used in the component mounting machine 1, and a production plan management device 82 for managing component mounting in the component mounting machine 1. And a component supply management device 9 that manages the supply of components to the component mounting machine 1.
　部品保管庫８１は、多数の部品供給リール７をそれぞれ決められた保管場所に保管する。この部品保管庫８１は、部品供給リール７を供給する供給口および部品供給リール７を受け取る返却口を有する。そして、部品保管庫８１は、部品補給管理装置９あるいはオペレーターからの要求に従って部品供給リール７をその保管場所から供給口へ排出し、オペレーターが返却口に返却した部品供給リール７をその保管場所に保管する。 The parts storage 81 stores a large number of parts supply reels 7 in a predetermined storage location. The component storage 81 has a supply port for supplying the component supply reel 7 and a return port for receiving the component supply reel 7. Then, the parts storage 81 discharges the parts supply reel 7 from the storage location to the supply port according to the request from the parts supply management device 9 or the operator, and the parts supply reel 7 returned to the return port by the operator is stored in the storage location. store.
　生産計画管理装置８２はサーバーコンピューターであり、基板Ｂに部品を実装することで部品実装基板を生産する生産計画Ｐｐに基づき部品実装機１を管理する。具体的には、生産計画管理装置８２は、基板Ｂに部品を実装する手順を示す基板データを生産計画Ｐｐに基づき作成して、当該基板データを部品実装機１に送信する。そして、部品実装機１は、受信した基板データに示される手順で基板Ｂへ部品を実装する。 The production plan management device 82 is a server computer and manages the component mounter 1 based on a production plan Pp for producing a component mounting board by mounting components on the board B. Specifically, the production plan management device 82 creates board data indicating a procedure for mounting components on the board B based on the production plan Pp, and transmits the board data to the component mounting machine 1. Then, the component mounter 1 mounts the component on the board B according to the procedure indicated by the received board data.
　部品補給管理装置９はサーバーコンピューターであり、制御部９１、記憶部９２、ＩＤリーダー９３およびユーザーインターフェース９４等を備える。制御部９１は、ＣＰＵ(Central Processing Unit)、ＲＡＭ(Random Access
Memory)およびＲＯＭ(Read Only Memory)で構成されたプロセッサーであり、所定の部品補給管理プログラムを実行することで取得部９１１および設定部９１３を内部に構築する。これらの動作は後に詳述する。 The parts supply management device 9 is a server computer and includes a control unit 91, a storage unit 92, an ID reader 93, a user interface 94, and the like. The control unit 91 includes a CPU (Central Processing Unit), a RAM (Random Access).
Memory) and a ROM (Read Only Memory). The acquisition unit 911 and the setting unit 913 are built in by executing a predetermined component supply management program. These operations will be described in detail later.
　記憶部９２はＨＤＤ(Hard Disk Drive)であり、生産計画管理装置８２から取得した生産計画Ｐｐを記憶する。さらに、記憶部９２は、部品供給リール７の使用履歴を当該部品供給リール７のリールＩＤ７３と対応付けた使用履歴情報Ｈ（図５）を記憶する。ここで、図５は部品供給リールの使用履歴情報の一例を模式的に示す図である。図５に示すように、使用履歴情報Ｈでは、部品供給リール７に収納される部品の残数、部品供給リール７の場所および使用期限が、リールＩＤ７３に対応付けられている。 The storage unit 92 is an HDD (Hard Disk Drive) and stores the production plan Pp acquired from the production plan management device 82. Further, the storage unit 92 stores use history information H (FIG. 5) in which the use history of the component supply reel 7 is associated with the reel ID 73 of the component supply reel 7. Here, FIG. 5 is a diagram schematically illustrating an example of usage history information of the component supply reel. As shown in FIG. 5, in the usage history information H, the remaining number of components stored in the component supply reel 7, the location of the component supply reel 7, and the expiration date are associated with the reel ID 73.
　部品供給リール７の場所としては、２通りの場所が存在する。つまり、対象の部品供給リール７が部品供給部２５に装着されている場合には、この部品供給リール７のフィーダー取付台車４での装着場所がリールＩＤ７３に対応付けられ、対象の部品供給リール７が部品保管庫８１に保管されている場合には、この部品供給リール７の保管場所がリールＩＤ７３に対応付けられる。 There are two places for the parts supply reel 7. That is, when the target component supply reel 7 is mounted on the component supply unit 25, the mounting location of the component supply reel 7 on the feeder mounting carriage 4 is associated with the reel ID 73, and the target component supply reel 7. Is stored in the component storage 81, the storage location of the component supply reel 7 is associated with the reel ID 73.
　また、使用期限については、部品実装機１で使用される複数のテープフィーダー５のうちには、使用期限を有する部品を部品供給リール７から供給するテープフィーダー５がある。このため、使用履歴情報Ｈでは、使用期限を有する部品を収納した部品供給リール７について、部品供給リール７のリールＩＤ７３と使用期限とが対応付けられている。 As for the expiration date, among the plurality of tape feeders 5 used in the component mounting machine 1, there is a tape feeder 5 that supplies a component having an expiration date from the component supply reel 7. For this reason, in the usage history information H, the reel ID 73 of the component supply reel 7 and the expiration date are associated with each other for the component supply reel 7 storing the components having the expiration date.
　図４に戻って説明を続ける。ＩＤリーダー９３はバーコードリーダーであり、部品供給リール７に付されたリールＩＤ７３および部品ＩＤ７４を読み取るのに使用される。なお、ＩＤリーダー９３は、無線により制御部９１と通信を行う可搬型のものであっても、有線で制御部９１と通信を行うものであっても良い。また、ユーザーインターフェース９４は、例えばタッチパネルディスプレイやスピーカー等で構成され、オペレーターからの入力操作を受け付けたり、オペレーターへの報知を行ったりする。特に、ユーザーインターフェース９４は、図５の使用履歴情報Ｈを表示する機能を果たす。 Referring back to FIG. The ID reader 93 is a bar code reader and is used to read the reel ID 73 and the component ID 74 attached to the component supply reel 7. The ID reader 93 may be a portable type that communicates with the control unit 91 wirelessly, or may communicate with the control unit 91 by wire. Further, the user interface 94 is configured by, for example, a touch panel display, a speaker, and the like, and accepts an input operation from the operator or notifies the operator. In particular, the user interface 94 functions to display the usage history information H of FIG.
　また、部品実装機１は、図１に示した機械的構成の他に、制御部１８を備える。制御部１８は、ＣＰＵ、ＲＡＭおよびＲＯＭで構成されたプロセッサーであり、生産計画管理装置８２から受信した基板データに示される手順で基板Ｂへの部品実装が実行されるように、制御を実行する。特に、この制御部１８は、テープフィーダー５に装着された部品供給リール７内の部品の残数を管理する機能も果たす。 The component mounter 1 includes a control unit 18 in addition to the mechanical configuration shown in FIG. The control unit 18 is a processor composed of a CPU, a RAM, and a ROM, and executes control so that component mounting on the board B is executed according to the procedure shown in the board data received from the production plan management device 82. . In particular, the control unit 18 also functions to manage the remaining number of components in the component supply reel 7 mounted on the tape feeder 5.
　図６は部品実装機の制御部が実行する部品残数管理の一例を示すフローチャートである。このフローチャートは、テープフィーダー５に装着された２個の部品供給リール７に残存する部品の総数である残存部品総数（換言すれば、テープフィーダー５に対応するリールホルダー６に保持される部品の総数）および使用位置Ｌｕに配置されている部品供給リール７の部品残数を管理し、部品実装に並行してテープフィーダー５毎に実行される。ステップＳ１０１では、テープフィーダー５が部品供給位置５０に部品を供給したかが確認される。そして、部品の供給が確認されると（ステップＳ１０１で「ＹＥＳ」）、残存部品総数がデクリメントされる（ステップＳ１０２）。また、ステップＳ１０２では、テープフィーダー５が部品供給に使用した部品供給リール７の部品残数が、当該部品供給リール７のリールＩＤ７３とともに部品補給管理装置９に通知され、部品補給管理装置９は、使用履歴情報Ｈで当該リールＩＤ７３に対応付けられた部品残数を更新する。 FIG. 6 is a flowchart showing an example of remaining component number management executed by the control unit of the component mounter. This flowchart shows the total number of remaining parts (in other words, the total number of parts held on the reel holder 6 corresponding to the tape feeder 5), which is the total number of parts remaining on the two parts supply reels 7 mounted on the tape feeder 5. ) And the remaining number of components of the component supply reel 7 arranged at the use position Lu, and is executed for each tape feeder 5 in parallel with component mounting. In step S <b> 101, it is confirmed whether the tape feeder 5 has supplied a component to the component supply position 50. When the supply of parts is confirmed (“YES” in step S101), the total number of remaining parts is decremented (step S102). In step S102, the remaining number of components on the component supply reel 7 used for component supply by the tape feeder 5 is notified to the component supply management device 9 together with the reel ID 73 of the component supply reel 7, and the component supply management device 9 The remaining part number associated with the reel ID 73 is updated with the usage history information H.
　ステップＳ１０３では、２個の部品供給リール７のうち、部品供給に使用中の部品供給リール７の部品が使い切られたか確認される。部品が使い切られていなく、部品切れが生じていない場合（ステップＳ１０３で「ＮＯ」の場合）には、ステップＳ１０１に戻る。なお、部品が使い切られたか否かは、適宜の基準に基づき判断できる。例えば、テープフィーダー５により供給された部品を吸着するための動作が実行された際に、部品の吸着・保持を確認できない場合には、吸着エラーが発生したと判断される。そこで、複数の吸着エラーが連続して発生したことを確認した場合に、部品が使い切られたと判断できる。あるいは、使用位置Ｌｕに配置されている部品供給リール７の部品残数がゼロになったことを確認した場合に、部品が使い切られたと判断できる。一方、部品切れが生じた場合（ステップＳ１０３で「ＹＥＳ」の場合）には、制御部１８は部品補給管理装置９の制御部９１に部品切れの発生を通知し（ステップＳ１０４）、制御部９１は、装着作業の実行をユーザーインターフェース９４によってオペレーターに報知する。また、ステップＳ１０４では、制御部１８は、図２のステップＳ１２～Ｓ１３のローディングをテープフィーダー５に実行させて、次の部品供給リール７を部品供給に使用する。 In step S103, it is confirmed whether the component supply reel 7 being used for component supply out of the two component supply reels 7 has been used up. If the part has not been used up and no part has run out (if “NO” in step S103), the process returns to step S101. Whether or not a part has been used up can be determined based on an appropriate standard. For example, when an operation for sucking a component supplied by the tape feeder 5 is executed, if it is not possible to confirm the suction / holding of the component, it is determined that a suction error has occurred. Therefore, when it is confirmed that a plurality of suction errors have occurred successively, it can be determined that the part has been used up. Alternatively, when it is confirmed that the number of remaining parts of the component supply reel 7 arranged at the use position Lu has become zero, it can be determined that the parts have been used up. On the other hand, if a component has run out (“YES” in step S103), the control unit 18 notifies the control unit 91 of the component replenishment management device 9 of the occurrence of component out (step S104). Notifies the operator through the user interface 94 of the execution of the mounting operation. In step S104, the control unit 18 causes the tape feeder 5 to execute the loading in steps S12 to S13 in FIG. 2, and uses the next component supply reel 7 for component supply.
　ステップＳ１０５では、新たに装着する部品供給リール７のリールＩＤ７３および部品ＩＤ７４（以下、「リールＩＤ７３等」と適宜称する）の取得を確認することで、オペレーターにより部品供給リール７の装着作業が実行されたかを把握する。つまり、オペレーターは、部品供給リール７のリールＩＤ７３等をＩＤリーダー９３により読み取ってから、当該部品供給リール７をテープフィーダー５に装着する（装着作業）。この際、リールＩＤ７３等は部品補給管理装置９から部品実装機１の制御部１８に送信される。 In step S105, by confirming the acquisition of the reel ID 73 and the component ID 74 (hereinafter, appropriately referred to as “reel ID 73 etc.”) of the component supply reel 7 to be newly mounted, the operator performs the component supply reel 7 mounting operation. Grasp That is, the operator reads the reel ID 73 and the like of the component supply reel 7 with the ID reader 93 and then mounts the component supply reel 7 on the tape feeder 5 (mounting operation). At this time, the reel ID 73 and the like are transmitted from the component supply management device 9 to the control unit 18 of the component mounter 1.
　制御部１８は、リールＩＤ７３等の取得が確認できない場合（ステップＳ１０５で「ＮＯ」の場合）には、テープフィーダー５が部品供給位置５０に部品を供給したかを確認する（ステップＳ１０６）。部品の供給が確認されない場合（ステップＳ１０６で「ＮＯ」の場合）にはステップＳ１０５に戻り、部品の供給が確認された場合（ステップＳ１０６で「ＹＥＳ」の場合）には、残存部品総数がデクリメントされる（ステップＳ１０７）。また、ステップＳ１０７では、テープフィーダー５が部品供給に使用した部品供給リール７の部品残数が、当該部品供給リール７のリールＩＤ７３とともに部品補給管理装置９に通知され、部品補給管理装置９は、使用履歴情報Ｈで当該リールＩＤ７３に対応付けられた部品残数を更新する。 When the acquisition of the reel ID 73 or the like cannot be confirmed (when “NO” in step S105), the control unit 18 confirms whether the tape feeder 5 has supplied the component to the component supply position 50 (step S106). If the supply of the component is not confirmed (“NO” in step S106), the process returns to step S105. If the supply of the component is confirmed (“YES” in step S106), the total number of remaining parts is decremented. (Step S107). In step S107, the remaining number of components on the component supply reel 7 used for component supply by the tape feeder 5 is notified to the component supply management device 9 together with the reel ID 73 of the component supply reel 7, and the component supply management device 9 The remaining part number associated with the reel ID 73 is updated with the usage history information H.
　ステップＳ１０８では、残存部品総数が閾個数以下となったかが確認される。残存部品総数が閾個数以下でない場合（ステップＳ１０８で「ＮＯ」の場合）には、ステップＳ１０５に戻る。ここで、閾個数は１以上の整数である。一方、残存部品総数が閾個数以下である場合（ステップＳ１０８で「ＹＥＳ」の場合）には、制御部１８は部品補給管理装置９の制御部９１に残数警告を行うように通知し（ステップＳ１０９）、ステップＳ１０５に戻る。制御部９１は、ステップＳ１０９での通知を受けて、残数警告をユーザーインターフェース９４によって実行する。なお、この残数警告は、対象のテープフィーダー５に対する残存部品総数が少なくなったため、装着作業を直ちに行うようにオペレーターに求めるものである。 In step S108, it is confirmed whether the total number of remaining parts is equal to or less than the threshold number. If the total number of remaining parts is not less than the threshold number (if “NO” in step S108), the process returns to step S105. Here, the threshold number is an integer of 1 or more. On the other hand, when the total number of remaining parts is equal to or less than the threshold number (in the case of “YES” in step S108), the control unit 18 notifies the control unit 91 of the component supply management device 9 to issue a remaining number warning (step S108). S109), the process returns to step S105. Upon receiving the notification in step S109, the control unit 91 executes a remaining number warning through the user interface 94. This remaining number warning is for the operator to immediately perform the mounting operation because the total number of remaining parts for the target tape feeder 5 has decreased.
　ステップＳ１０５で、リールＩＤ７３等の取得が確認された場合（ステップＳ１０５で「ＹＥＳ」の場合）には、残存部品総数が更新される（ステップＳ１１０）。具体的には、取得されたリールＩＤ７３について使用履歴情報Ｈが示す部品残数を部品補給管理装置９から取得して加算することで、残存部品総数が更新される。この際、残数警告が発生している状況でリールＩＤ７３等の取得が確認された場合には、残存部品総数の更新とともに残数警告が解除される。また、ステップＳ１１０では、ステップＳ１０５で取得された部品ＩＤ７４が部品の使用期限を含む場合には、その使用期限がステップＳ１０５で取得されたリールＩＤ７３とともに部品補給管理装置９に通知され、部品補給管理装置９は、この使用期限をリールＩＤ７３に対応付けて使用履歴情報Ｈに登録する。そして、ステップＳ１０１に戻る。これらステップＳ１０１～Ｓ１１０は、部品実装でのテープフィーダー５の使用が終了するまで実行される。 If acquisition of the reel ID 73 or the like is confirmed in step S105 (in the case of “YES” in step S105), the total number of remaining parts is updated (step S110). Specifically, the remaining number of parts is updated by acquiring the remaining number of parts indicated by the usage history information H for the acquired reel ID 73 from the parts supply management device 9 and adding it. At this time, if the acquisition of the reel ID 73 or the like is confirmed in a situation where the remaining number warning is generated, the remaining number warning is canceled together with the update of the total number of remaining parts. In step S110, when the part ID 74 acquired in step S105 includes the part use time limit, the use time limit is notified to the part supply management device 9 together with the reel ID 73 acquired in step S105, and the part supply management is performed. The device 9 registers the usage expiration date in the usage history information H in association with the reel ID 73. Then, the process returns to step S101. These steps S101 to S110 are executed until the use of the tape feeder 5 in the component mounting is finished.
　このように、部品実装機１において部品実装の実行に伴って部品供給リール７の部品切れが生じた場合には、オペレーターは、部品供給リール７の装着作業により部品を補給する補給作業を実行する必要がある。そこで、部品補給管理装置９は、部品実装機１に対して部品実装に並行して実行すべき装着作業の実行時期（装着時期）を設定する。特に、１度の補給作業で複数のテープフィーダー５に対してまとめて装着作業を実行できるように、装着時間の設定を行う。 As described above, when the component supply reel 7 has run out due to the component mounting in the component mounting machine 1, the operator performs a replenishment operation for replenishing the component by the mounting operation of the component supply reel 7. There is a need. Therefore, the component supply management device 9 sets the execution time (mounting time) of the mounting work to be performed in parallel with component mounting on the component mounting machine 1. In particular, the mounting time is set so that the mounting work can be collectively performed on the plurality of tape feeders 5 in one replenishment work.
　図７は部品補給管理装置が実行する装着時間設定の一例を示すフローチャートである。このフローチャートは制御部９１の取得部９１１および設定部９１３により実行される。ステップＳ２０１では、取得部９１１が生産計画管理装置８２から生産計画Ｐｐを取得して記憶部９２に保存する。ステップＳ２０２では、部品実装機１に生産計画Ｐｐを実行させた場合に、テープフィーダー５に対して装着作業が実行可能となる期間（装着可能期間）が、部品実装機１に装着された複数のテープフィーダーのそれぞれについて設定部９１３により予測される。 FIG. 7 is a flowchart showing an example of setting of the mounting time executed by the parts supply management device. This flowchart is executed by the acquisition unit 911 and the setting unit 913 of the control unit 91. In step S <b> 201, the acquisition unit 911 acquires the production plan Pp from the production plan management device 82 and stores it in the storage unit 92. In step S <b> 202, when the component mounting machine 1 is caused to execute the production plan Pp, a period during which the mounting operation can be performed on the tape feeder 5 (a mounting period) is a plurality of the mounting machines 1 mounted on the component mounting machine 1. The setting unit 913 predicts each of the tape feeders.
　つまり、図３を示して説明したように、テープフィーダー５に装着された２個の部品供給リール７のうちスプロケット５７により先行して送られる一の部品供給リール７が使い切られた後は、後続の部品供給リール７からの部品供給テープＴＰが自動的にスプロケット５７に係合して送られることで部品供給が続行される。オペレーターは、このように部品供給が続行される間に、別の部品供給リール７をテープフィーダー５に装着する装着作業を実行できる。したがって、２個の部品供給リール７のうち一の部品供給リール７が使い切られる時間が装着可能期間の開始時間として算出される。一方、図６を示して説明したように、一の部品供給リール７が使い切られた後は、残存部品総数が閾個数以下となると残数警告が報知されるため、この残数警告の報知前に装着作業を行うことが好適となる。したがって、残存部品総数が閾個数となる時間（すなわち、残数警告が報知される時間）が装着可能期間の終了時間として算出される。 That is, as described with reference to FIG. 3, after one of the two component supply reels 7 mounted on the tape feeder 5 is used up by the sprocket 57 and is used up, The component supply tape TP from the component supply reel 7 is automatically engaged with and sent to the sprocket 57, so that the component supply is continued. The operator can execute a mounting operation of mounting another component supply reel 7 on the tape feeder 5 while the component supply is continued in this way. Therefore, the time when one of the two component supply reels 7 is used up is calculated as the start time of the mountable period. On the other hand, as described with reference to FIG. 6, after one component supply reel 7 has been used up, a remaining number warning is notified when the total number of remaining parts falls below the threshold number. It is preferable to perform the mounting operation. Therefore, the time when the total number of remaining parts becomes the threshold number (that is, the time when the remaining number warning is notified) is calculated as the end time of the mountable period.
　なお、テープフィーダー５に装着された部品供給リール７の部品残数の変化は、使用履歴情報Ｈおよび生産計画Ｐｐに基づき予測できる。つまり、対象の部品供給リール７が部品供給リール７に取り付けられた時点で収納する部品残数（初期部品残数）は、使用履歴情報Ｈにおいて当該部品供給リール７のリールＩＤ７３に対応付けられた部品残数を参照することで取得できる。そして、生産計画Ｐｐにおいて当該部品供給リール７の部品が供給される回数を初期部品残数から減算することで、当該部品供給リール７の部品残数を算出できる。以下に示すフローチャートにおいても、部品供給リール７の部品残数は、使用履歴情報Ｈおよび生産計画Ｐｐを適宜参照することで、同様に算出される。 It should be noted that the change in the number of remaining parts of the parts supply reel 7 mounted on the tape feeder 5 can be predicted based on the usage history information H and the production plan Pp. That is, the remaining component count (initial component remaining count) stored when the target component supply reel 7 is attached to the component supply reel 7 is associated with the reel ID 73 of the component supply reel 7 in the usage history information H. It can be acquired by referring to the number of remaining parts. Then, the number of remaining parts of the component supply reel 7 can be calculated by subtracting the number of times the parts of the component supply reel 7 are supplied from the initial number of remaining parts in the production plan Pp. Also in the flowchart shown below, the number of remaining parts of the component supply reel 7 is calculated in the same manner by appropriately referring to the use history information H and the production plan Pp.
　図８は図７のフローチャートに従って実行される装着可能期間の算出結果の一例を示す図である。図８の例では、５台のテープフィーダー５Ａ～５Ｅを対象とした装着時間の設定例が示されている。ただし、対象となるテープフィーダー５の台数は、ここの例の５台に当然限られない。図８では、ハッチングの濃淡により状態の違いが示されており、最も濃いハッチングの期間は、２個の部品供給リール７の両方で部品切れが生じていない期間に相当し、次に濃いハッチングの期間は、一の部品供給リール７で部品切れが生じてから残数警告が報知されるまでの期間に相当し、最も淡いハッチングの期間は、残数警告が報知された以後の期間に相当する。 FIG. 8 is a diagram showing an example of the calculation result of the wearable period executed according to the flowchart of FIG. In the example of FIG. 8, an example of setting the mounting time for five tape feeders 5A to 5E is shown. However, the number of target tape feeders 5 is not limited to the five in this example. In FIG. 8, the difference in state is shown by the shade of the hatching, and the darkest hatching period corresponds to a period in which no part breakage occurs in both of the two parts supply reels 7, and the next darkest hatching The period corresponds to a period from when a component is cut out in one component supply reel 7 until the remaining number warning is notified, and the lightest hatching period corresponds to a period after the remaining number warning is notified. .
　図８の例によると、テープフィーダー５Ａ、５Ｂ、５Ｃ、５Ｄに対しては、それぞれ時間ｔ１ａ、ｔ１ｂ、ｔ１ｃ、ｔ１ｄで一の部品供給リール７に部品切れが発生する。また、テープフィーダー５Ａ、５Ｂに対しては、それぞれ時間ｔ２ａ、ｔ２ｂで残数警告が報知される。その結果、ステップＳ２０２では、テープフィーダー５Ａ、５Ｂ、５Ｃ、５Ｄに対して、それぞれ装着可能期間Ｔａ、Ｔｂ、Ｔｃ、Ｔｄで装着作業が実行できると算出される。 According to the example in FIG. 8, for the tape feeders 5A, 5B, 5C, and 5D, one component supply reel 7 runs out at time t1a, t1b, t1c, and t1d. Further, a remaining number warning is notified to the tape feeders 5A and 5B at times t2a and t2b, respectively. As a result, in step S202, it is calculated that the mounting work can be performed on the tape feeders 5A, 5B, 5C, and 5D in the mounting possible periods Ta, Tb, Tc, and Td, respectively.
　図７のステップＳ２０３では、複数のテープフィーダー５のうち、装着可能期間Ｔａ、Ｔｂ、Ｔｃ、Ｔｄが重複する複数の候補フィーダーが、設定部９１３により特定される。特に、複数のテープフィーダー５のうち、残数警告が最初に報知されるテープフィーダー５Ａの装着可能期間Ｔａに、その他のテープフィーダー５の装着可能期間が重複するように、候補フィーダーが特定される。ここの例では、具体的には、重複期間Ｔｏにおいて、装着可能期間Ｔａ、Ｔｂ、Ｔｄが重複しているため、３個のテープフィーダー５Ａ、５Ｂ、５Ｄが候補フィーダーとして特定される。 7, among the plurality of tape feeders 5, a plurality of candidate feeders whose mounting possible periods Ta, Tb, Tc, and Td overlap are specified by the setting unit 913. In particular, among the plurality of tape feeders 5, candidate feeders are specified such that the other tape feeders 5 can be installed in the same period Ta during which the tape feeder 5 </ b> A is notified of the remaining number warning first. . In this example, specifically, in the overlap period To, the mountable periods Ta, Tb, and Td overlap, so that three tape feeders 5A, 5B, and 5D are specified as candidate feeders.
　ステップＳ２０４では、候補フィーダー５Ａ、５Ｂ、５Ｄの装着可能期間Ｔａ、Ｔｂ、Ｔｄに重複するように装着時間ｔｓが、設定部９１３により設定される。具体的には、装着可能期間Ｔａ、Ｔｂ、Ｔｄが重複する重複期間Ｔｏの開始時間ｔ１ｂ、換言すれば、候補フィーダー５Ａ、５Ｂ、５Ｄのうち一の部品供給リール７の部品切れが最後に発生する時間ｔ１ｂが装着時間ｔｓに設定される。こうして、３台の候補フィーダー５Ａ、５Ｂ、５Ｄに対して装着時間ｔｓが共通化され、１度の補給作業でこれら候補フィーダー５Ａ、５Ｂ、５Ｄへの装着作業をまとめて実行することが可能となる。なお、装着時間ｔｓは、必ずしも時間ｔ１ｂに一致している必要は無く、時間ｔ１ｂより後に設定されても構わない。つまり、装着時間ｔｓは重複期間Ｔｏに重複する適宜の時間に設定することができる。 In step S204, the setting unit 913 sets the mounting time ts so as to overlap the mounting possible periods Ta, Tb, Td of the candidate feeders 5A, 5B, 5D. Specifically, the start time t1b of the overlap period To in which the mountable periods Ta, Tb, and Td overlap, in other words, one part supply reel 7 of the candidate feeders 5A, 5B, and 5D is finally cut out. The time t1b to be set is set as the mounting time ts. In this way, the mounting time ts is made common to the three candidate feeders 5A, 5B, and 5D, and it is possible to execute the mounting work on these candidate feeders 5A, 5B, and 5D in a single replenishment operation. Become. Note that the mounting time ts is not necessarily coincident with the time t1b, and may be set after the time t1b. That is, the wearing time ts can be set to an appropriate time that overlaps the overlapping period To.
　なお、図７および図８では、１つの装着時間ｔｓを設定する場合を例示した。しかしながら、複数の装着時間ｔｓを設定することもできる。つまり、上述の要領で１回目の装着時間ｔｓ１を設定し、当該装着時間ｔｓ１で装着作業が実行されたと仮定した上で、さらに上述の要領でステップＳ２０２～Ｓ２０４を実行して２回目の装着時間ｔｓ２を設定することができる。そして、これらを繰り返すことで、３回目以後の装着時間ｔｓも適宜設定できる。 7 and 8 exemplify the case where one mounting time ts is set. However, a plurality of mounting times ts can be set. That is, after setting the first mounting time ts1 in the above-described manner and assuming that the mounting operation has been executed in the mounting time ts1, the steps S202 to S204 are further performed in the above-described manner to perform the second mounting time. ts2 can be set. And by repeating these, the mounting time ts after the third time can be set as appropriate.
　ところで、上述のとおり、部品実装機１では使用期限を有する部品供給リール７が用いられる。したがって、使用期限を有する部品供給リール７を用いるテープフィーダー５（以下、「期限部品テープフィーダー５」と適宜称する）に対する装着時間ｔｓは、当該テープフィーダー５に装着中の部品供給リール７の使用期限以前に設定される必要がある。ここで、装着中の部品供給リール７とは、テープフィーダー５で使用中および待機中の部品供給リール７を示し、部品が使い切られた部品供給リール７は含まない。そこで、図７および図８に示した装着時間設定によって装着時間ｔｓが暫定的に設定されると、次の使用期限判定が実行される。 By the way, as described above, the component mounter 1 uses the component supply reel 7 having an expiration date. Accordingly, the mounting time ts for the tape feeder 5 using the component supply reel 7 having the expiration date (hereinafter referred to as “expired component tape feeder 5” as appropriate) is the expiration date of the component supply reel 7 being mounted on the tape feeder 5. Must be set before. Here, the component supply reel 7 being mounted refers to the component supply reel 7 being used and in standby by the tape feeder 5, and does not include the component supply reel 7 in which the component has been used up. Therefore, when the mounting time ts is provisionally set by the mounting time setting shown in FIGS. 7 and 8, the next expiration date determination is executed.
　図９は使用期限判定の一例を示すフローチャートである。図９の使用期限判定は、制御部９１の設定部９１３により実行される。ステップＳ３０１では、期限部品テープフィーダー５に対して暫定的に設定された装着時間ｔｓ（ｎ）が、当該テープフィーダー５に装着中の部品供給リール７の使用期限以前であるかが判定される。なお、テープフィーダー５には２個の部品供給リール７が装着されるが、通常は先に使用される先行の部品供給リール７の使用期限が後に使用される後続の部品供給リール７の使用期限より早い。したがって、当該テープフィーダー５に装着された２個の部品供給リール７のうち、先行の部品供給リール７（換言すれば、装着可能期間の開始時刻で部品が切れる部品供給リール７）の使用期限と、装着時間ｔｓ（ｎ）とを比較すれば良い。 FIG. 9 is a flowchart showing an example of expiration date determination. The expiration date determination in FIG. 9 is executed by the setting unit 913 of the control unit 91. In step S <b> 301, it is determined whether the mounting time ts (n) provisionally set for the time limit component tape feeder 5 is before the time limit for using the component supply reel 7 being mounted on the tape feeder 5. Note that two component supply reels 7 are mounted on the tape feeder 5, but the expiration date of the preceding component supply reel 7 that is normally used first is the expiration date of the subsequent component supply reel 7 that is used later. Faster. Therefore, of the two component supply reels 7 mounted on the tape feeder 5, the expiration date of the preceding component supply reel 7 (in other words, the component supply reel 7 whose components are cut at the start time of the mountable period) The mounting time ts (n) may be compared.
　そして、暫定の装着時間ｔｓ（ｎ）が使用期限以前である場合（ステップＳ３０１で「ＹＥＳ」の場合）には、当該暫定の装着時間ｔｓ（ｎ）は適正と判定される（ステップＳ３０２）。一方、暫定の装着時間ｔｓ（ｎ）が使用期限より後である場合（ステップＳ３０１で「ＮＯ」の場合）には、当該暫定の装着時間ｔｓ（ｎ）は不適と判定される（ステップＳ３０３）。 If the provisional attachment time ts (n) is before the expiration date (“YES” in step S301), the provisional attachment time ts (n) is determined to be appropriate (step S302). On the other hand, if the provisional mounting time ts (n) is after the expiration date (“NO” in step S301), the provisional mounting time ts (n) is determined to be inappropriate (step S303). .
　使用期限判定の結果、装着時間ｔｓ（ｎ）が不適と判定された場合については、図１３～図１７等を用いて後述する。一方、使用期限判定の結果、装着時間ｔｓ（ｎ）が適正であれば、期限部品テープフィーダー５に対する装着作業を装着時間ｔｓ（ｎ）に応じたタイミングで実行すると決定し、その決定内容は、ユーザーインターフェース９４を介してオペレーターに報知される。つまり、装着時間ｔｓ（ｎ）に装着作業を実行するように報知し、オペレーターは装着時間ｔｓに応じた適宜のタイミングで装着作業を実行する。 As a result of the expiration date determination, the case where the mounting time ts (n) is determined to be inappropriate will be described later with reference to FIGS. On the other hand, as a result of the expiration date determination, if the mounting time ts (n) is appropriate, it is determined that the mounting work for the time-limited component tape feeder 5 is executed at a timing corresponding to the mounting time ts (n). An operator is notified via the user interface 94. That is, it is notified that the mounting work is executed at the mounting time ts (n), and the operator executes the mounting work at an appropriate timing according to the mounting time ts.
　あるいは、装着時間ｔｓ（ｎ）が適正である場合には、次に説明する期限部品装着時間決定を実行することで、期限部品テープフィーダー５の装着時間をさらに調整しても良い。図１０は部品補給管理装置が実行する期限部品装着時間決定の第１例を示すフローチャートであり、図１１および図１２は図１０のフローチャートでの演算処理の一例をタイミングチャートで模式的に示す図である。これらに示す期限部品装着時間決定は、制御部９１の設定部９１３により実行される。なお、以下では、装着時間ｔｓの回数ｎを明示するために、装着時間ｔｓにその回数ｎ（ｎは１以上の整数）を適宜付する。 Alternatively, when the installation time ts (n) is appropriate, the installation time of the expiration date part tape feeder 5 may be further adjusted by executing the expiration date component installation time determination described below. FIG. 10 is a flowchart showing a first example of determining the time limit part mounting time executed by the parts supply management device, and FIGS. 11 and 12 are diagrams schematically showing an example of the arithmetic processing in the flowchart of FIG. 10 in a timing chart. It is. The deadline component mounting time determination shown here is executed by the setting unit 913 of the control unit 91. In the following, in order to clearly indicate the number n of the wearing time ts, the number n (n is an integer of 1 or more) is appropriately added to the wearing time ts.
　図１１では、期限部品装着時間決定の実行対象である期限部品テープフィーダー５Ｂと、当該テープフィーダー５Ｂに対する装着時間の決定に関与する別のテープフィーダー５Ａ、５Ｃとが示されている。図１１での表記は、図８のそれと同様である。 FIG. 11 shows a deadline component tape feeder 5B, which is an execution target of the deadline component attachment time determination, and other tape feeders 5A and 5C involved in the determination of the attachment time for the tape feeder 5B. The notation in FIG. 11 is the same as that in FIG.
　図１２のタイミングチャートでは、テープフィーダー５Ｂに対する残存部品総数を縦軸とし、時間を横軸として、互いに異なる４種類の部品実装基板Ｂ１～Ｂ４を順番に生産する生産計画Ｐｐの実行に伴う残存部品総数の変化が示されている。基板Ｂ１～Ｂ４の種類の違いに応じて、部品が使用されるレート（単位時間あたりに供給される部品の個数）が異なる。そのため、生産する基板Ｂ１～Ｂ４が変更される度に、部品の使用レート、すなわちタイミングチャートの傾きが変わる。 In the timing chart of FIG. 12, the total number of remaining parts for the tape feeder 5B is taken as the vertical axis, and the time is taken as the horizontal axis, and the remaining parts accompanying the execution of the production plan Pp for sequentially producing four different types of component mounting boards B1 to B4. The change in the total number is shown. The rate at which components are used (the number of components supplied per unit time) varies depending on the types of the substrates B1 to B4. Therefore, every time the boards B1 to B4 to be produced are changed, the component usage rate, that is, the inclination of the timing chart changes.
　図１１および図１２に示すように、時間ｔ１において、テープフィーダー５Ｂに装着された２個の部品供給リール７のうち先に使用される先行の部品供給リール７が使い切られて、装着可能期間Ｔｂが開始する。この時間ｔ１において、先行の部品供給リール７は、テープフィーダー５Ｂに装着中でなくなり、その部品供給テープＴＰはテープフィーダー５Ｂから排出される。また、時間ｔ１以後は、２個の部品供給リール７のうち後に使用される後続の部品供給リール７が使用されることとなる。 As shown in FIGS. 11 and 12, at time t1, the preceding component supply reel 7 used first out of the two component supply reels 7 mounted on the tape feeder 5B is used up, and the mountable period Tb. Starts. At time t1, the preceding component supply reel 7 is not being mounted on the tape feeder 5B, and the component supply tape TP is discharged from the tape feeder 5B. Further, after the time t1, the subsequent component supply reel 7 to be used later of the two component supply reels 7 is used.
　上述したように、図１０のフローチャートの前に実行される図７のフローチャートでは、テープフィーダー５Ｂに対して装着時間ｔｓ（ｎ）が暫定的に設定される。図１１に示す例では、暫定の装着時間ｔｓ（ｎ）は、テープフィーダー５Ａ、５Ｂの装着可能期間Ｔａ、Ｔｂに重複して設定されている。したがって、装着時間ｔｓ（ｎ）においては、テープフィーダー５Ａ、５Ｂに対する装着作業をまとめて実行することができる。 As described above, in the flowchart of FIG. 7 executed before the flowchart of FIG. 10, the mounting time ts (n) is provisionally set for the tape feeder 5B. In the example shown in FIG. 11, the provisional attachment time ts (n) is set to overlap with the attachment possible periods Ta and Tb of the tape feeders 5A and 5B. Therefore, in the mounting time ts (n), the mounting work for the tape feeders 5A and 5B can be executed collectively.
　これに対して、図１０のフローチャートが開始されると、装着時間ｔｓ（ｎ）の次の装着時間ｔｓ（ｎ＋１）が取得される（ステップＳ４０１）。この次の装着時間ｔｓ（ｎ＋１）は、図７のフローチャートによって、図１０の実行対象となるテープフィーダー５Ｂとは別の複数のテープフィーダー５（テープフィーダー５Ｃを含む）の装着可能期間（装着可能期間Ｔｃを含む）に重複して設定されたものである。したがって、次の装着時間ｔｓ（ｎ＋１）においては、これら複数のテープフィーダー５に対する装着作業をまとめて実行することができる。 On the other hand, when the flowchart of FIG. 10 is started, a mounting time ts (n + 1) next to the mounting time ts (n) is acquired (step S401). This next mounting time ts (n + 1) is determined according to the flowchart of FIG. 7 in the mounting possible period (mountable) of a plurality of tape feeders 5 (including the tape feeder 5C) different from the tape feeder 5B to be executed in FIG. (Including the period Tc). Therefore, in the next mounting time ts (n + 1), the mounting work for the plurality of tape feeders 5 can be executed collectively.
　そして、ステップＳ４０２では、次の装着時間ｔｓ（ｎ＋１）が、期限部品テープフィーダー５Ｂに装着中の部品供給リール７（換言すれば、装着可能期間Ｔｂの開始後に使用される後続の部品供給リール７）の使用期限以前か否かが判断される。次の装着時間ｔｓ（ｎ＋１）が使用期限より後の場合（ステップＳ４０２で「ＮＯ」の場合）には、ステップ４０３に進んで、テープフィーダー５Ｂに対しては、先の装着時間ｔｓ（ｎ）に応じたタイミングで装着作業を実行すると決定する。また、ステップＳ４０３での決定内容は、ユーザーインターフェース９４によってオペレーターに報知される。 In step S402, the next mounting time ts (n + 1) is the component supply reel 7 that is being mounted on the time limit component tape feeder 5B (in other words, the subsequent component supply reel 7 that is used after the start of the mountable period Tb). ) Is before the expiration date. When the next mounting time ts (n + 1) is after the expiration date (in the case of “NO” in step S402), the process proceeds to step 403, and the previous mounting time ts (n) for the tape feeder 5B. It is determined that the mounting operation is executed at a timing according to the condition. Further, the contents of the determination in step S403 are notified to the operator by the user interface 94.
　一方、次の装着時間ｔｓ（ｎ＋１）が使用期限以前の場合（ステップＳ４０２で「ＹＥＳ」の場合）には、ステップＳ４０４で、次の装着時間ｔｓ（ｎ＋１）における期限部品テープフィーダー５Ｂの残存部品総数Ｑ（ｎ＋１）（図１２）が予測され、ステップＳ４０５で、残存部品総数Ｑ（ｎ＋１）が閾個数以下であるかが判断される。 On the other hand, if the next mounting time ts (n + 1) is before the expiration date (“YES” in step S402), in step S404, the remaining parts of the time limit component tape feeder 5B at the next mounting time ts (n + 1). The total number Q (n + 1) (FIG. 12) is predicted, and it is determined in step S405 whether the remaining part total number Q (n + 1) is equal to or less than the threshold number.
　残存部品総数Ｑ（ｎ＋１）が閾個数以下である場合には、テープフィーダー５Ｂの装着可能期間Ｔｂが次の装着時間ｔｓ（ｎ＋１）より前に終了していることとなる。したがって仮に先の装着時間ｔｓ（ｎ）でテープフィーダー５Ｂに装着作業を実行しなかったとすると、次の装着時間ｔｓ（ｎ＋１）までに残数警告が発生する。そこで、テープフィーダー５Ｂに対しては、先の装着時間ｔｓ（ｎ）で装着作業を実行すると決定して（ステップＳ４０３）、その決定内容がユーザーインターフェース９４によってオペレーターに報知される。 When the total number of remaining parts Q (n + 1) is equal to or less than the threshold number, the mountable period Tb of the tape feeder 5B ends before the next mounting time ts (n + 1). Therefore, if the mounting operation is not performed on the tape feeder 5B in the previous mounting time ts (n), a remaining number warning is generated by the next mounting time ts (n + 1). Therefore, the tape feeder 5B is determined to perform the mounting operation at the previous mounting time ts (n) (step S403), and the determined content is notified to the operator by the user interface 94.
　一方、残存部品総数Ｑ（ｎ＋１）が閾個数より多い場合には、図１１に示すように、テープフィーダー５Ｂの装着可能期間Ｔｂが次の装着時間ｔｓ（ｎ＋１）以後まで継続していることとなる。したがって、仮に先の装着時間ｔｓ（ｎ）でテープフィーダー５Ｂに装着作業を実行しなかったとしても、少なくとも次の装着時間ｔｓ（ｎ＋１）までテープフィーダー５Ｂに対する残数警告が発生しない。この場合には、ステップＳ４０１に戻って、次の装着時間ｔｓが取得される。つまり、装着時間ｔｓ（ｎ＋２）を新たな次の装着時間ｔｓとするとともに、装着時間ｔｓ（ｎ＋１）を新たな先の装着時間ｔｓとして、ステップＳ４０２～Ｓ４０５が再実行される。そして、ステップＳ４０２で「ＮＯ」あるいはステップＳ４０５で「ＹＥＳ」と判断されるまで、ステップＳ４０１～Ｓ４０５が実行される。 On the other hand, when the total number of remaining parts Q (n + 1) is larger than the threshold number, as shown in FIG. 11, the mountable period Tb of the tape feeder 5B continues until the next mounting time ts (n + 1). Become. Therefore, even if the mounting operation is not performed on the tape feeder 5B in the previous mounting time ts (n), the remaining number warning for the tape feeder 5B does not occur at least until the next mounting time ts (n + 1). In this case, the process returns to step S401 to acquire the next mounting time ts. In other words, the mounting time ts (n + 2) is set as the new next mounting time ts, and the mounting time ts (n + 1) is set as the new previous mounting time ts, and steps S402 to S405 are executed again. Steps S401 to S405 are executed until “NO” in step S402 or “YES” in step S405.
　図１１および図１２の例では、装着可能期間Ｔｂは、不図示の次の装着時間ｔｓ（ｎ＋２）よりも前に終了し、すなわち次の装着時間ｔｓ（ｎ＋２）の時点では、残存部品総数が閾個数以下になる（ステップＳ４０５で「ＹＥＳ」）。そこで、テープフィーダー５Ｂに対しては、先の装着時間ｔｓ（ｎ＋１）に応じたタイミングで装着作業を実行すると決定し（ステップＳ４０３）、その決定内容がユーザーインターフェース９４によってオペレーターに報知される。その結果、テープフィーダー５Ｂ、５Ｃの装着可能期間Ｔｂ、Ｔｃに重複するように、テープフィーダー５Ｂの装着時間ｔｓ（ｎ＋１）が設定される。 In the example of FIGS. 11 and 12, the mountable period Tb ends before the next mounting time ts (n + 2) (not shown), that is, at the time of the next mounting time ts (n + 2), The number is equal to or less than the threshold number (“YES” in step S405). Therefore, it is determined that the mounting operation is performed at the timing corresponding to the previous mounting time ts (n + 1) for the tape feeder 5B (step S403), and the determined content is notified to the operator by the user interface 94. As a result, the mounting time ts (n + 1) of the tape feeder 5B is set so as to overlap the mounting possible periods Tb and Tc of the tape feeders 5B and 5C.
　かかるフローチャートによれば、テープフィーダー５Ｂの装着可能期間Ｔｂに重複する複数の装着時間ｔｓのうちの使用期限より前の装着時間ｔｓのうち、最も遅い装着時間ｔｓに、テープフィーダー５Ｂの装着時間ｔｓが設定されることとなる。換言すれば、この最も遅い装着時間ｔｓに応じたタイミングで、テープフィーダー５Ｂへの装着作業を実行すると決定される。 According to this flowchart, the mounting time ts of the tape feeder 5B is set to the latest mounting time ts among the mounting times ts of the plurality of mounting times ts that overlap the mounting possible period Tb of the tape feeder 5B. Will be set. In other words, it is determined that the mounting operation to the tape feeder 5B is executed at the timing corresponding to the latest mounting time ts.
　このように、第１例では、使用期限を有する部品供給リール７の部品を供給する期限部品テープフィーダー５Ｂ（一のフィーダー）に対する装着時間ｔｓが、装着中の部品供給リール７の使用期限以前に設定される。これによって、装着中の部品供給リール７の使用期限が経過する前に、部品供給リール７を装着して部品の補給作業を実行できる。しかも、当該期限部品テープフィーダー５Ｂに対する装着時間ｔｓ（ｎ＋１）を別のテープフィーダー５Ｃの装着可能期間Ｔｃに重複させて、テープフィーダー５Ｂ、５Ｃそれぞれに対して同一の装着時間ｔｓ（ｎ＋１）が設定される。したがって、これらのテープフィーダー５Ｂ、５Ｃに対する装着作業を１回の部品補給でまとめて実行することができる。こうして、その頻度を抑制しつつも、部品の使用期限に応じた適切なタイミングで、補給作業を実行することが可能となっている。 Thus, in the first example, the mounting time ts for the component tape feeder 5B (one feeder) for supplying components of the component supply reel 7 having the expiration date is before the expiration date of the component supply reel 7 being mounted. Is set. Thus, before the expiration date of the component supply reel 7 being mounted elapses, the component supply reel 7 can be mounted and the component replenishment operation can be performed. Moreover, the same mounting time ts (n + 1) is set for each of the tape feeders 5B and 5C by overlapping the mounting time ts (n + 1) for the time limit part tape feeder 5B with the mounting possible period Tc of another tape feeder 5C. Is done. Therefore, it is possible to collectively perform the mounting work on these tape feeders 5B and 5C with one part replenishment. In this way, it is possible to perform the replenishment operation at an appropriate timing according to the expiration date of the parts while suppressing the frequency.
　また、第１例では、期限部品テープフィーダー５Ｂに対する装着時間ｔｓを、当該一のテープフィーダー５Ｂの装着可能期間Ｔｂと、別のテープフィーダー５Ｃの装着可能期間Ｔｃとに重複するように設定する。したがって、各テープフィーダー５Ｂ、５Ｃに装着された部品供給リール７が部品切れを起こす前に、各テープフィーダー５Ｂ、５Ｃに対する装着作業をまとめて実行することができる。 In the first example, the mounting time ts for the time limit part tape feeder 5B is set so as to overlap the mounting possible period Tb of the one tape feeder 5B and the mounting possible period Tc of another tape feeder 5C. Therefore, before the component supply reels 7 mounted on the tape feeders 5B and 5C run out of components, it is possible to collectively perform mounting operations on the tape feeders 5B and 5C.
　また、上記の例では、テープフィーダー５Ｂの装着可能期間Ｔｂと重複する装着可能期間Ｔａ、Ｔｃを有する２個の別のテープフィーダー５Ａ、５Ｃが少なくとも存在する（なお、２個の別のテープフィーダー５Ａ、５Ｃそれぞれの装着可能期間Ｔａ、Ｔｃは重複しない）。そこで、２個の別のテープフィーダー５Ａ、５Ｃそれぞれの装着可能期間Ｔａ、Ｔｃのうち遅い方の装着可能期間Ｔｃに重複するように、期限部品テープフィーダー５Ｂに対する装着時間ｔｓ（ｎ＋１）が設定される。かかる構成では、期限部品テープフィーダー５Ｂの装着可能期間Ｔｂが経過しない範囲で、当該期限部品テープフィーダー５Ｂに対する装着時間ｔｓ（ｎ＋１）をできるだけ遅く設定することができる。これによって、この装着時間ｔｓ（ｎ＋１）に応じたタイミングで開封されて装着される部品供給リール７の開封時間を遅らせることができ、その結果、部品を長く使用することができる。 In the above example, there are at least two separate tape feeders 5A and 5C having mounting periods Ta and Tc that overlap with the mounting period Tb of the tape feeder 5B (note that there are two separate tape feeders). The wearable periods Ta and Tc of 5A and 5C do not overlap each other). Therefore, the mounting time ts (n + 1) for the expiring part tape feeder 5B is set so as to overlap with the later mounting possible period Tc of the two other tape feeders 5A and 5C. The In such a configuration, it is possible to set the mounting time ts (n + 1) to the time limit component tape feeder 5B as late as possible within a range in which the mountable period Tb of the time limit component tape feeder 5B does not elapse. As a result, it is possible to delay the opening time of the component supply reel 7 that is opened and mounted at a timing corresponding to the mounting time ts (n + 1), and as a result, the components can be used for a long time.
　ちなみに、図１０を用いた説明から明らかなように、期限部品テープフィーダー５Ｂの装着可能期間Ｔｂと重複する装着可能期間を有する別のテープフィーダー５が３個以上存在する場合にも同様の管理が実行される。つまり、先の装着時間ｔｓが設定されたテープフィーダー５および次の装着時間ｔｓが設定されたテープフィーダー５（２個の別のテープフィーダー５）を切り換えながら（ステップＳ４０１）、ステップＳ４０２～Ｓ４０５が同様に実行される。その結果、最終的に対象となった２個の別のテープフィーダー５それぞれの装着可能期間のうち遅い方の装着可能期間に重複するように、期限部品テープフィーダー５Ｂに対する装着時間ｔｓを設定して、部品を長く使用することができる。 Incidentally, as is apparent from the description using FIG. 10, the same management is performed when there are three or more other tape feeders 5 having a mountable period overlapping with the mountable period Tb of the term part tape feeder 5B. Executed. That is, while switching between the tape feeder 5 in which the previous mounting time ts is set and the tape feeder 5 (two other tape feeders 5) in which the next mounting time ts is set (step S401), steps S402 to S405 are performed. It is executed in the same way. As a result, the mounting time ts for the expiring part tape feeder 5B is set so as to overlap the later mounting possible period of each of the two other tape feeders 5 that are finally targeted. The parts can be used for a long time.
　続いては、使用期限判定の結果、装着時間ｔｓ（ｎ）が不適と判定された場合に実行される期限部品装着時間決定について説明する。なお、以下では、上記の例との差異点を中心に説明することとし、共通点は相当符号を付して適宜説明を省略する。ただし、共通する構成を具備することで、同様の効果が奏されることは言うまでもない。 Subsequently, description will be given of determination of the time limit component mounting time executed when the mounting time ts (n) is determined to be inappropriate as a result of the usage time limit determination. In the following description, differences from the above example will be mainly described, and common points will be denoted by corresponding reference numerals and description thereof will be omitted as appropriate. However, it goes without saying that the same effect can be achieved by providing a common configuration.
　図１３は部品補給管理装置が実行する期限部品装着時間決定の第２例を示すフローチャートであり、図１４および図１５は図１３のフローチャートでの演算処理の一例をタイミングチャートで模式的に示す図である。これらに示す期限部品装着時間決定は、制御部９１の設定部９１３により実行される。 FIG. 13 is a flowchart illustrating a second example of determining the time limit component mounting time executed by the component supply management apparatus, and FIGS. 14 and 15 are diagrams schematically illustrating an example of the arithmetic processing in the flowchart of FIG. 13 in a timing chart. It is. The deadline component mounting time determination shown here is executed by the setting unit 913 of the control unit 91.
　第２例での図１４および図１５の表記は、第１例での図１１および図１２の表記と同様である。ただし、第２例では、図７のフローチャートで期限部品テープフィーダー５Ｂに対して暫定的に設定された装着時間ｔｓ（ｎ）が、当該テープフィーダー５Ｂに装着中の先行の部品供給リール７の使用期限ｔｒより後になっている。 14 and 15 in the second example are the same as those in FIGS. 11 and 12 in the first example. However, in the second example, the mounting time ts (n) provisionally set for the time limit component tape feeder 5B in the flowchart of FIG. 7 is the use of the preceding component supply reel 7 being mounted on the tape feeder 5B. It is after the deadline tr.
　かかる場合、図７のフローチャートで設定された装着時間ｔｓのうちから、使用期限ｔｒ以前の装着時間ｔｓが探索される（ステップＳ５０１）。具体的には、ステップＳ５０１では、使用期限ｔｒ以前の装着時間ｔｓのうち、最も遅い装着時間ｔｓが探索される。その結果、図１４に示す例では、テープフィーダー５Ａ、５Ｃの装着可能期間Ｔａ、Ｔｃに重複して設定された装着時間ｔｓ（ｎ－１）が探索結果として見つかる。そして、ステップＳ５０２では、期限部品テープフィーダー５Ｂに対する装着作業を、この装着時間ｔｓ（ｎ－１）に応じたタイミングで実行すると決定し、その決定内容は、ユーザーインターフェース９４を介してオペレーターに報知される。 In such a case, the mounting time ts before the expiration date tr is searched from the mounting time ts set in the flowchart of FIG. 7 (step S501). Specifically, in step S501, the latest wearing time ts is searched for among the wearing times ts before the expiration date tr. As a result, in the example shown in FIG. 14, the mounting time ts (n−1) set to overlap the mounting possible periods Ta and Tc of the tape feeders 5A and 5C is found as a search result. In step S502, it is determined that the mounting operation for the time limit component tape feeder 5B is to be executed at a timing corresponding to the mounting time ts (n-1), and the details of the determination are notified to the operator via the user interface 94. The
　このように、第２例では、期限部品テープフィーダー５Ｂ（一のフィーダー）の装着可能期間Ｔｂの開始前に、テープフィーダー５Ｂに装着中の部品供給リール７の使用期限ｔｒが経過するか否かが予測される。そして、使用期限ｔｒの経過が予測されると、使用期限ｔｒ以前に、それぞれの装着可能期間Ｔａ、Ｔｃが互いに重複する複数の別のテープフィーダー５Ａ、５Ｃに対して設定された装着時間ｔｓ（ｎ－１）が探索される。そして、この装着時間ｔｓ（ｎ－１）がテープフィーダー５Ｂに対する装着時間ｔｓに設定される。こうして、テープフィーダー５Ｂに対する装着時間ｔｓ（ｎ－１）を、テープフィーダー５Ａ、５Ｃの装着可能期間Ｔａ、Ｔｃに重複させつつ、使用期限ｔｒ以前に設定する。これによって、期限部品テープフィーダー５Ｂに装着中の部品供給リール７の使用期限ｔｒの経過前に、当該テープフィーダー５Ｂに対する装着作業を確実に実行できるとともに、当該テープフィーダー５Ｂに対する装着作業を、複数の別のテープフィーダー５Ａ、５Ｃに対する装着作業とまとめて、１回の補給作業で実行することが可能となる。 Thus, in the second example, whether or not the expiration date tr of the component supply reel 7 being mounted on the tape feeder 5B has passed before the start of the mountable period Tb of the limit component tape feeder 5B (one feeder). Is predicted. When the expiration of the expiration date tr is predicted, the mounting times ts () set for the plurality of other tape feeders 5A and 5C whose mounting possible periods Ta and Tc overlap each other before the expiration date tr. n-1) is searched. The mounting time ts (n−1) is set as the mounting time ts for the tape feeder 5B. In this way, the mounting time ts (n−1) for the tape feeder 5B is set before the expiration date tr while overlapping the mounting possible periods Ta and Tc of the tape feeders 5A and 5C. Thereby, before the expiration date tr of the component supply reel 7 being mounted on the time limit component tape feeder 5B, the mounting operation on the tape feeder 5B can be surely executed, and the mounting operation on the tape feeder 5B can be performed in a plurality of ways. It is possible to perform a single replenishment operation together with the mounting operation for the different tape feeders 5A and 5C.
　あるいは、この場合には、テープフィーダー５Ａ、５Ｃに対する装着時間ｔｓ（ｎ－１）を調整しても良い。具体的には、テープフィーダー５Ａ、５Ｃの装着可能期間Ｔａ、Ｔｃの重複期間の開始時間に設定されていた装着時間ｔｓ（ｎ－１）を、開始時間より後の重複期間内の時間であって使用期限ｔｒ以前の時間に変更することができる。これによって、部品供給リール７の開封時間を遅らせることができ、その結果、部品供給リール７の使用期限を遅らせて、部品を長く使用することができる。 Alternatively, in this case, the mounting time ts (n−1) for the tape feeders 5A and 5C may be adjusted. Specifically, the mounting time ts (n−1) set as the start time of the overlapping period of the tape feeders 5A and 5C that can be mounted is the time within the overlapping period after the start time. And can be changed to a time before the expiration date tr. As a result, the opening time of the component supply reel 7 can be delayed. As a result, the expiration date of the component supply reel 7 can be delayed and the component can be used for a long time.
　さらには、次のような変形例でも構わない。つまり、使用期限ｔｒ以前の装着時間ｔｓを探索するステップＳ５０１に代えて、使用期限ｔｒ以前に互いに装着可能期間Ｔａ、Ｔｃが重複するテープフィーダー５Ａ、５Ｃを探索するステップを実行する。そして、ステップＳ５０２に代えて、探索されたテープフィーダー５Ａ、５Ｂの装着可能期間Ｔａ、Ｔｃが互いに重複する重複期間Ｔｏ内であって使用期限ｔｒ以前の例えば装着時間ｔｓ´（ｎ－１）を、テープフィーダー５Ａ～５Ｂに対して設定するステップを実行する。この際、装着時間ｔｓ´（ｎ－１）で装着可能になったことを報知しても良く、あるいは装着作業を開始しても良い。この変形例によっても、期限部品テープフィーダー５Ｂに装着中の部品供給リール７の使用期限ｔｒの経過前に、当該テープフィーダー５Ｂに対する装着作業を、複数の別のテープフィーダー５Ａ、５Ｃに対する装着作業とまとめて、１回の補給作業で実行することが可能となる。 Furthermore, the following modifications may be possible. That is, instead of step S501 for searching for the mounting time ts before the expiration date tr, a step of searching for tape feeders 5A and 5C in which the mounting possible periods Ta and Tc overlap before the expiration date tr is executed. Then, instead of step S502, for example, a mounting time ts ′ (n−1) within the overlap period To where the mounting possible periods Ta and Tc of the searched tape feeders 5A and 5B overlap each other and before the expiration date tr is obtained. Then, a setting step is executed for the tape feeders 5A to 5B. At this time, it may be notified that the mounting is possible at the mounting time ts ′ (n−1), or the mounting operation may be started. Also according to this modification, before the expiration date tr of the component supply reel 7 being mounted on the time limit component tape feeder 5B elapses, the mounting work on the tape feeder 5B is replaced with the mounting work on a plurality of other tape feeders 5A and 5C. In summary, it can be executed by one replenishment operation.
　なお、この補給作業では、補給作業の実行時に使用中の先行の部品供給リール７を取り外して、新たな部品供給リール７を装着するとともに、待機していた部品供給リール７にローディングを実行する。 In this replenishment operation, the preceding component supply reel 7 in use is removed when the replenishment operation is performed, a new component supply reel 7 is mounted, and loading is performed on the standby component supply reel 7.
　図１６は部品補給管理装置が実行する期限部品装着時間決定の第３例を示すフローチャートであり、図１７は図１６のフローチャートでの演算処理の一例をタイミングチャートで模式的に示す図である。これらに示す期限部品装着時間決定は、制御部９１の設定部９１３により実行される。 FIG. 16 is a flowchart showing a third example of deadline component mounting time determination executed by the parts supply management device, and FIG. 17 is a diagram schematically showing an example of the arithmetic processing in the flowchart of FIG. The deadline component mounting time determination shown here is executed by the setting unit 913 of the control unit 91.
　第３例での図１７の表記は、第１例での図１１の表記と同様である。ただし、第３例では、図７のフローチャートで期限部品テープフィーダー５Ｂに対して暫定的に設定された装着時間ｔｓ（ｎ）が、当該テープフィーダー５Ｂに装着中の先行の部品供給リール７の使用期限ｔｒより後になっている。 The notation of FIG. 17 in the third example is the same as the notation of FIG. 11 in the first example. However, in the third example, the mounting time ts (n) provisionally set for the time limit component tape feeder 5B in the flowchart of FIG. 7 is the use of the preceding component supply reel 7 being mounted on the tape feeder 5B. It is after the deadline tr.
　かかる場合、装着可能期間が使用期限ｔｒに重複するテープフィーダー５が特定される。その結果、図１７の例では、装着可能期間Ｔａ、Ｔｃを有するテープフィーダー５Ａ、５Ｃが特定される。そして、特定されたテープフィーダー５Ａ、５Ｃおよび期限部品テープフィーダー５Ｂに対する装着時間ｔｓを使用期限ｔｒに設定すると決定し（ステップＳ６０２）、その決定内容は、ユーザーインターフェース９４を介してオペレーターに報知される。 In such a case, the tape feeder 5 whose mounting possible period overlaps the expiration date tr is specified. As a result, in the example of FIG. 17, the tape feeders 5A and 5C having the mountable periods Ta and Tc are specified. Then, it is determined that the mounting time ts with respect to the specified tape feeders 5A and 5C and the time limit part tape feeder 5B is set as the use time limit tr (step S602), and the determination content is notified to the operator via the user interface 94. .
　このように、第３例では、期限部品テープフィーダー５Ｂに装着中の部品供給リール７の使用期限ｔｒに装着可能期間Ｔａ、Ｔｃが重複する別のテープフィーダー５Ａ、５Ｃが、複数のテープフィーダー５のうちから予測される。そして、期限部品テープフィーダー５Ｂおよびテープフィーダー５Ａ、５Ｃそれぞれに対する同一の装着時間ｔｓとして使用期限ｔｒが設定される。かかる構成では、期限部品テープフィーダー５Ｂに装着中の部品供給リール７の使用期限ｔｒが経過するタイミングで、一のテープフィーダー５Ｂへの装着作業と別のテープフィーダー５Ａ、５Ｃへの装着作業とを、１回の補給作業でまとめて実行できる。 As described above, in the third example, the different tape feeders 5A and 5C in which the mountable periods Ta and Tc overlap the expiration date tr of the component supply reel 7 being mounted on the time limit component tape feeder 5B are the plurality of tape feeders 5. Predicted from Then, the expiration date tr is set as the same mounting time ts for each of the time limit part tape feeder 5B and the tape feeders 5A, 5C. In such a configuration, at the timing when the expiration date tr of the component supply reel 7 being mounted on the limit component tape feeder 5B elapses, the mounting operation on one tape feeder 5B and the mounting operation on another tape feeder 5A, 5C are performed. It can be executed collectively in one replenishment operation.
　図１８は部品補給管理装置が実行する期限部品装着時間決定の第４例を示すフローチャートである。この期限部品装着時間決定は、制御部９１の設定部９１３により実行される。この第４例は、上記の第２例および第３例と異なり、図９の使用期限判定で暫定の装着時間ｔｓ（ｎ）が適正と判断された場合に実行され、特に装着時間ｔｓ（ｎ）に応じた装着作業で期限部品テープフィーダー５Ｂに対していずれの部品供給リール７を装着するかを決定する。 FIG. 18 is a flowchart showing a fourth example of determining the time limit component mounting time executed by the component supply management device. This deadline component mounting time determination is executed by the setting unit 913 of the control unit 91. Unlike the second and third examples described above, the fourth example is executed when the provisional mounting time ts (n) is determined to be appropriate in the expiration date determination of FIG. 9, and particularly the mounting time ts (n ) To determine which component supply reel 7 is to be mounted on the time limit component tape feeder 5B.
　ステップＳ７０１では、テープフィーダー５Ｂへの装着作業で使用可能な開封済みの部品供給リール７が存在するかが判断される。具体的には、テープフィーダー５Ｂで供給予定の部品と同種の部品を収納する開封済みの部品供給リール７が部品保管庫８１に保管されているかが、使用履歴情報Ｈに基づき判断される。該当する開封済みの部品供給リール７が存在しない場合（ステップＳ７０１で「ＮＯ」の場合）には、このテープフィーダー５Ｂに対して、未開封の部品供給リール７を装着時間ｔｓに応じた装着作業で装着すると決定する（ステップＳ７０２）。 In step S701, it is determined whether there is an unsealed component supply reel 7 that can be used in the mounting operation on the tape feeder 5B. Specifically, based on the usage history information H, it is determined whether or not the unsealed component supply reel 7 storing the same type of component as the component to be supplied by the tape feeder 5B is stored in the component storage 81. When there is no corresponding unsealed component supply reel 7 (in the case of “NO” in step S701), an unopened component supply reel 7 is mounted on the tape feeder 5B according to the mounting time ts. (Step S702).
　一方、該当する開封済みの部品供給リール７（対象収納部材）が存在する場合（ステップＳ７０１で「ＹＥＳ」の場合）には、開封済みの部品供給リール７が使用履歴情報Ｈに示される使用期限に基づき昇順に（換言すれば、使用期限が早い順に）ソートされる（ステップＳ７０３）。そして、ソート順序を示す変数Ｊがゼロにリセットされ（ステップＳ７０４）、変数Ｊがインクリメントされる（ステップＳ７０５）。 On the other hand, if there is a corresponding unsealed component supply reel 7 (target storage member) (in the case of “YES” in step S701), the expiration date for which the unsealed component supply reel 7 is indicated in the usage history information H Are sorted in ascending order (in other words, in order from the earliest expiration date) (step S703). Then, the variable J indicating the sort order is reset to zero (step S704), and the variable J is incremented (step S705).
　ステップＳ７０６では、Ｊ番目の部品供給リール７を装着時間ｔｓに装着すると仮定し、ステップＳ７０７では、生産計画Ｐｐの実行に伴ってＪ番目の部品供給リール７の部品が使い切られる時間を予測する。そして、当該時間において、Ｊ番目の部品供給リール７の使用期限が経過するか否かが予測される（ステップＳ７０８）。 In step S706, it is assumed that the J-th component supply reel 7 is mounted at the mounting time ts, and in step S707, the time for which the components of the J-th component supply reel 7 are used up with the execution of the production plan Pp is predicted. Then, it is predicted whether or not the expiration date of the J-th component supply reel 7 will elapse during that time (step S708).
　Ｊ番目の部品供給リール７の部品が使い切られる時刻において、当該部品供給リール７の使用期限が経過しないと判断した場合（ステップＳ７０８で「ＮＯ」の場合）には、Ｊ番目の部品供給リール７（一の対象収納部材）を、装着時間ｔｓに応じた装着作業で対象のテープフィーダー５Ｂに装着すると決定する（ステップＳ７０９）。一方、使用期限が経過すると判断した場合（ステップＳ７０８で「ＹＥＳ」の場合）には、ステップＳ７１０に進んで、変数Ｊが最大値Ｊｘに一致したか否かが判断される。ここで、最大値Ｊｘは、使用可能な開封済みの部品供給リール７（対象収納部材）の個数である。そして、ステップＳ７０８で「ＮＯ」と判断されるか、変数Ｊが最大値Ｊｘとなるまで、ステップＳ７０６～Ｓ７０８が繰り返される。 If it is determined that the expiration date of the component supply reel 7 has not elapsed at the time when the components of the Jth component supply reel 7 are used up (if “NO” in step S708), the Jth component supply reel 7 It is determined that (one target storage member) is to be mounted on the target tape feeder 5B by the mounting operation according to the mounting time ts (step S709). On the other hand, when it is determined that the expiration date has passed (in the case of “YES” in step S708), the process proceeds to step S710 to determine whether or not the variable J matches the maximum value Jx. Here, the maximum value Jx is the number of usable component supply reels 7 (target storage members) that can be used. Steps S706 to S708 are repeated until “NO” is determined in step S708 or until the variable J reaches the maximum value Jx.
　つまり、Ｊｘ個の開封済みの部品供給リール７のうち、ステップＳ７０８で使用期限が経過しないと判断される部品供給リール７（一の対象収納部材）が存在すれば、この部品供給リール７を、装着時間ｔｓに応じた装着作業で対象のテープフィーダー５に装着すると決定する（ステップＳ７０９）。一方、該当の部品供給リール７が存在しない場合には、未開封の部品供給リール７（一の対象収納部材）を装着時間ｔｓに応じた装着作業で対象のテープフィーダー５Ｂに装着すると決定する（ステップＳ７０２）。また、ステップＳ７０２あるいはＳ７０９での決定結果は、ユーザーインターフェース９４を介してオペレーターに報知される。 That is, if there is a component supply reel 7 (one target storage member) determined that the expiration date has not passed in step S708 among the Jx unsealed component supply reels 7, this component supply reel 7 is It is determined to be mounted on the target tape feeder 5 by a mounting operation according to the mounting time ts (step S709). On the other hand, when the corresponding component supply reel 7 does not exist, it is determined that the unopened component supply reel 7 (one target storage member) is mounted on the target tape feeder 5B by the mounting operation according to the mounting time ts ( Step S702). The determination result in step S702 or S709 is notified to the operator via the user interface 94.
　このように、第４例では、期限部品テープフィーダー５Ｂ（一のフィーダー）に装着可能な部品供給リール７として、使用期限が互いに異なる複数の部品供給リール７（対象収納部材）が存在する場合、複数の部品供給リール７それぞれの使用期限と生産計画Ｐｐとに基づき、テープフィーダー５に装着する部品供給リール７が選択される。かかる構成では、生産計画Ｐｐに対して適切な使用期限を有する部品供給リール７をテープフィーダー５Ｂに装着することができる。 Thus, in the fourth example, when there are a plurality of component supply reels 7 (target storage members) having different expiration dates as the component supply reels 7 that can be mounted on the limit component tape feeder 5B (one feeder), Based on the expiration date of each of the plurality of component supply reels 7 and the production plan Pp, the component supply reel 7 to be mounted on the tape feeder 5 is selected. In such a configuration, the component supply reel 7 having an appropriate expiration date for the production plan Pp can be mounted on the tape feeder 5B.
　特に、装着時間ｔｓ（ｎ）でテープフィーダー５Ｂに装着したと仮定した場合に、生産計画Ｐｐの実行に伴って部品切れが発生する予想時間より使用期限が後となる部品供給リール７のうち、使用期限が最も早い部品供給リール７を、テープフィーダー５Ｂに装着すると決定する。かかる構成では、テープフィーダー５Ｂに装着中の部品供給リール７の使用期限が生産計画Ｐｐの実行途中に切れるのを抑制しつつ、使用期限の短い部品供給リール７を有効活用することができる。 In particular, when it is assumed that the tape feeder 5B is mounted at the mounting time ts (n), among the component supply reels 7 whose expiry date is later than the expected time when the component shortage occurs with the execution of the production plan Pp, It is determined that the component supply reel 7 with the earliest expiration date is mounted on the tape feeder 5B. In such a configuration, it is possible to effectively utilize the component supply reel 7 having a short expiration date while suppressing the expiration date of the component supply reel 7 being mounted on the tape feeder 5B from being cut off during the execution of the production plan Pp.
