Description

印刷機Printer
　本明細書は、印刷機について開示する。 This specification discloses a printing machine.
　従来、対象物に粘性流体を印刷する印刷機で使用される交換部材を自動交換するものが知られている。例えば、特許文献１には、スクリーンマスクを含む交換可能部材を収納し、印刷機の前方に配設された状態で当該印刷機との間で交換可能部材を搬出入する収納装置を備えるものが開示されている。収納装置は、スクリーンマスクとその他の交換可能部材（スキージや基板支持部材）が取り付けられた搬送治具とを収納可能な収納部と、収納部に収納されている部材を前後に搬送する搬送コンベアと、を有する。印刷機は、印刷処理部と基板固定部との間に配設され、前後方向に延びた左右一対の搬送レールを有する。印刷機は、スクリーンマスクを搬送レール上から退避させたり、搬送レールを用いて搬送治具を引き入れて交換可能部材を交換したり、スクリーンマスクを引き入れて搬送レール上に保持したりする。 Conventionally, there are known devices that automatically replace exchangeable parts used in printing machines that print a viscous fluid on an object. For example, Patent Document 1 discloses a device that includes a storage device that stores exchangeable parts including a screen mask and is disposed in front of the printing machine to transport exchangeable parts between the printing machine and the device. The storage device has a storage section that can store the screen mask and a transport jig to which other exchangeable parts (squeegee and substrate support member) are attached, and a transport conveyor that transports the parts stored in the storage section back and forth. The printing machine has a pair of left and right transport rails that are disposed between the print processing section and the substrate fixing section and extend in the front-rear direction. The printing machine retracts the screen mask from above the transport rails, uses the transport rails to pull in the transport jig to replace exchangeable parts, and pulls in the screen mask and holds it on the transport rails.
国際公開第２０１８／１０５０１６号公報International Publication No. 2018/105016
　上述した印刷機では、スクリーンマスクや搬送治具が印刷機と収納装置との間で移動する際、スクリーンマスクや搬送治具の外枠と搬送レールの枠受け部とが擦れて摩耗し、摩耗粉が発生する。搬送レール上に摩耗粉が生じると、摩耗粉により搬送摩擦が大きくなり、スクリーンマスクや搬送治具の搬送に支障が生じるおそれがある。また、経年使用によって摩耗粉が蓄積すると、スクリーンマスクが蓄積した摩耗粉に乗り上げることで、スクリーンマスクの平坦度を低下させるおそれもある。 In the printing machine described above, when the screen mask and transport jig move between the printing machine and the storage device, the outer frames of the screen mask and transport jig rub against the frame receiving portion of the transport rail, causing wear and generating wear powder. When wear powder is generated on the transport rail, the wear powder increases transport friction, which may cause problems in transporting the screen mask and transport jig. In addition, when wear powder accumulates over time, the screen mask may ride up on the accumulated wear powder, which may reduce the flatness of the screen mask.
　本開示は、経年使用に拘わらず、スクリーンマスクや交換部材が取り付けられた搬送治具の搬送をスムーズに行なうことができる印刷機を提供することを主目的とする。 The primary objective of this disclosure is to provide a printing machine that can smoothly transport a transport jig equipped with a screen mask or replacement parts, regardless of long-term use.
　本開示は、上述の主目的を達成するために以下の手段を採った。 This disclosure takes the following steps to achieve the above-mentioned primary objective:
　本開示の印刷機は、
　スクリーンマスクを用いて対象物に粘性流体を印刷すると共に前記スクリーンマスクを含む複数種類の交換部材を搬送して交換可能な印刷機であって、
　水平方向に延在し、前記スクリーンマスクの搬送に用いられる一対の第１搬送面と、
　前記一対の第１搬送面の延在方向と平行に延在し、前記スクリーンマスクとは異なる他の交換部材が取り付けられた搬送治具の搬送に用いられる第２搬送面と、
　を備えることを要旨とする。 The printing machine of the present disclosure comprises:
A printing machine that uses a screen mask to print a viscous fluid on an object and is capable of transporting and replacing a plurality of types of replacement parts including the screen mask,
a pair of first transport surfaces extending in a horizontal direction and used for transporting the screen mask;
a second transport surface extending parallel to the extending direction of the pair of first transport surfaces and used for transporting a transport jig having an exchange member other than the screen mask attached thereto;
The gist of the invention is to provide the following:
　この本開示の印刷機では、スクリーンマスクの搬送とスクリーンマスクとは異なる他の交換部材の搬送とにそれぞれ異なる搬送面（第１搬送面、第２搬送面）を用いることとしている。搬送面を分散させることで、摩耗粉の発生を低減させることができる。この結果、スクリーンマスクやその他の交換部材の交換に際して、経年使用に拘わらず、スクリーンマスクや交換部材が取り付けられた搬送治具の搬送をスムーズに行なうことができる。 In the printing machine disclosed herein, different transport surfaces (first transport surface, second transport surface) are used for transporting the screen mask and for transporting replacement parts other than the screen mask. By dispersing the transport surfaces, the generation of wear powder can be reduced. As a result, when replacing the screen mask or other replacement parts, the transport jig to which the screen mask or replacement parts are attached can be transported smoothly, regardless of long-term use.

　本実施形態の印刷機１０は、スキージ２２を用いてスクリーンマスクＭ上のはんだペーストをスクリーンマスクＭに形成されたパターン孔に押し込むことにより当該パターン孔を介して下方の基板Ｓにはんだペーストを印刷するものである。印刷機１０は、はんだが印刷された基板Ｓに電子部品を実装する部品実装機と組み合わされて生産ラインを構成する。更に、印刷機１０は、生産する基板Ｓの種類を変更する際に、基板Ｓの種類に合わせて、スクリーンマスクＭや基板Ｓを支持する基板支持部材３２の自動交換が可能である。 The printer 10 of this embodiment uses a squeegee 22 to push the solder paste on the screen mask M into pattern holes formed in the screen mask M, thereby printing the solder paste onto the substrate S below through the pattern holes. The printer 10 is combined with a component mounter that mounts electronic components onto the substrate S on which the solder has been printed to form a production line. Furthermore, when changing the type of substrate S to be produced, the printer 10 is capable of automatically replacing the screen mask M and the substrate support member 32 that supports the substrate S according to the type of substrate S.
　印刷機１０は、図１，図２に示すように、印刷機本体１１と、印刷機本体１１を収容する筐体１２と、交換装置５０と、収容ラック６０と、印刷機全体を制御する図示しない制御装置と、を備える。印刷機本体１１は、ヘッド装置２０と、基板搬送装置３０と、認識部３５と、搬送レール４０と、を有する。 As shown in Figures 1 and 2, the printer 10 includes a printer main body 11, a housing 12 that houses the printer main body 11, an exchange device 50, a storage rack 60, and a control device (not shown) that controls the entire printer. The printer main body 11 includes a head device 20, a substrate transport device 30, a recognition unit 35, and transport rails 40.
　ヘッド装置２０は、印刷機本体１１の上段部に設置されている。ヘッド装置２０は、図１に示すように、ヘッド本体２１と、ヘッド本体２１を印刷方向である前後方向（Ｙ軸方向）に移動させるヘッド移動部２６と、を備える。ヘッド移動部２６は、前後方向に延在するガイドレール２８と、ガイドレール２８に沿って移動するＹ軸スライダ２７と、Ｙ軸スライダ２７を駆動する図示しないモータと、を有する。ヘッド本体２１は、図２に示すように、前後一対のスキージ２２と、例えばエアシリンダにより構成され対応するスキージ２２を昇降させるスキージ昇降部２３と、プッシャ２４と、例えばエアシリンダにより構成されプッシャ２４を昇降させるプッシャ昇降部２５と、を有する。一対のスキージ２２は、印刷方向に直交する左右方向（Ｘ軸方向）に延びる板状部材であり、左右方向から見て下方に向かうにつれて互いに離間するように傾斜する。印刷機本体１１の中段部には前後に延在する一対の搬送レール４０が設置されており、プッシャ２４は、プッシャ昇降部２５により下降させられた状態で、ヘッド移動部２６により前後に移動させられることで、搬送レール４０上の交換フレーム７０，８０を前後に押して移動させる。交換フレーム７０，８０は、図２に示すように、筐体１２の前面中段部に設けられた通過口３６を介して筐体１２の内外に移動する。なお、通過口３６には、交換フレーム７０，８０の通過を検知する検知センサ３７が設けられている。 The head device 20 is installed in the upper part of the printer body 11. As shown in FIG. 1, the head device 20 includes a head body 21 and a head moving unit 26 that moves the head body 21 in the front-rear direction (Y-axis direction), which is the printing direction. The head moving unit 26 has a guide rail 28 extending in the front-rear direction, a Y-axis slider 27 that moves along the guide rail 28, and a motor (not shown) that drives the Y-axis slider 27. As shown in FIG. 2, the head body 21 has a pair of front and rear squeegees 22, a squeegee lifting unit 23 that is, for example, an air cylinder, that lifts and lowers the corresponding squeegee 22, a pusher 24, and a pusher lifting unit 25 that is, for example, an air cylinder, that lifts and lowers the pusher 24. The pair of squeegees 22 are plate-shaped members that extend in the left-right direction (X-axis direction) perpendicular to the printing direction, and are inclined so as to move away from each other as they move downward when viewed from the left-right direction. A pair of transport rails 40 extending forward and backward are installed in the middle of the printer body 11, and the pusher 24, lowered by the pusher lifting unit 25, is moved forward and backward by the head moving unit 26, thereby pushing and moving the replacement frames 70, 80 on the transport rails 40 forward and backward. As shown in FIG. 2, the replacement frames 70, 80 move in and out of the housing 12 through a passage opening 36 provided in the middle of the front of the housing 12. The passage opening 36 is provided with a detection sensor 37 that detects the passage of the replacement frames 70, 80.
　基板搬送装置３０は、印刷機本体１１の下段部に設置されている。基板搬送装置３０は、基板Ｓを搬入して位置決め支持すると共に、基板ＳをスクリーンマスクＭ（裏面）に接触・離間させるものである。基板搬送装置３０は、図２に示すように、基板Ｓを左右方向（Ｘ軸方向）に搬送する基板搬送部３１と、基板Ｓを下方から支持するバックアップ部材としての基板支持部材３２と、基板支持部材３２を昇降させる基板支持部材昇降部３３と、を備える。基板支持部材３２は、基板Ｓの種類に応じて当該基板Ｓを支持するのに適したサイズのものに交換される。 The substrate transport device 30 is installed in the lower section of the printer body 11. The substrate transport device 30 loads and positions the substrate S, and also brings the substrate S into contact with and away from the screen mask M (rear surface). As shown in FIG. 2, the substrate transport device 30 includes a substrate transport section 31 that transports the substrate S in the left-right direction (X-axis direction), a substrate support member 32 as a backup member that supports the substrate S from below, and a substrate support member lifting section 33 that raises and lowers the substrate support member 32. The substrate support member 32 is replaced with one of a size suitable for supporting the substrate S depending on the type of substrate S.
　認識部３５は、基板Ｓや基板支持部材３２を認識するものである。認識部３５は、基板搬送装置３０により搬送され位置決めされた基板Ｓの上面に付されたマークを読み取って基板Ｓの位置を認識したり、搬送レール４０上の交換フレーム８０に支持された基板支持部材３２の底面に付されたマークを読み取って基板支持部材３２の位置やサイズを認識したりする。 The recognition unit 35 recognizes the substrate S and the substrate support member 32. The recognition unit 35 recognizes the position of the substrate S by reading marks attached to the top surface of the substrate S that has been transported and positioned by the substrate transport device 30, and recognizes the position and size of the substrate support member 32 by reading marks attached to the bottom surface of the substrate support member 32 that is supported by the exchange frame 80 on the transport rail 40.
　交換装置５０は、交換フレーム７０，８０を用いて印刷機本体１１で使用される交換部材（スクリーンマスクＭや基板支持部材３２）を収容した収容ラック６０を受け入れ、収容ラック６０と印刷機本体１１との間で交換部材を搬送するものである。交換装置５０は、印刷機本体１１の前面における左側に設置された左側ユニット５１ａと、印刷機本体１１の前面における右側に設置された右側ユニット５１ｂと、を備える。左側ユニット５１ａおよび右側ユニット５１ｂは、収容ラック６０を受け入れてその下面を左右両側から支持するラック支持部材５２と、ラック支持部材５２を昇降させるラック昇降部５３と、を有する。ラック昇降部５３は、例えばボールねじ機構とモータとの組み合わせや、リニアモータにより構成される。ラック支持部材５２に支持された収容ラック６０は、ラック昇降部５３よりラック支持部材５２と共に昇降する。更に、左側ユニット５１ａおよび右側ユニット５１ｂは、収容ラック６０内の交換フレーム７０，８０をベルトやローラ等により左右両側面から前後に送るフレーム前後移動部５４を有する。 The exchange device 50 receives the storage rack 60 that stores the replacement parts (screen mask M and substrate support member 32) used in the printer body 11 using the replacement frames 70, 80, and transports the replacement parts between the storage rack 60 and the printer body 11. The exchange device 50 includes a left unit 51a installed on the left side of the front of the printer body 11, and a right unit 51b installed on the right side of the front of the printer body 11. The left unit 51a and the right unit 51b each have a rack support member 52 that receives the storage rack 60 and supports its lower surface from both the left and right sides, and a rack lifting unit 53 that raises and lowers the rack support member 52. The rack lifting unit 53 is composed of, for example, a combination of a ball screw mechanism and a motor, or a linear motor. The storage rack 60 supported by the rack support member 52 is raised and lowered together with the rack support member 52 by the rack lifting unit 53. Furthermore, the left unit 51a and the right unit 51b have a frame front-rear movement part 54 that moves the replacement frames 70, 80 in the storage rack 60 forward and backward from both the left and right sides using belts, rollers, etc.
　収容ラック６０は、図１に示すように、左右一対の支持レール６１を上下に複数段有し、各支持レール６１に交換部材を収容可能な収容体である。また、収容ラック６０の印刷機本体１１と前面と背面とには開口部６２，６３が形成されている。交換部材は、前面側の開口部６２を介して作業者等により出し入れされ、背面側の開口部６３を介してフレーム前後移動部５４により搬入出される。フレーム前後移動部５４は、交換装置５０に収容ラック６０が受け入れられた状態で、収容ラック６０の複数段の支持レール６１のうちラック昇降部５３により印刷機本体１１の搬送レール４０と略同じ高さに位置する支持レール６１に支持された交換部材を印刷機本体１１へ送り出す。また、フレーム前後移動部５４は、印刷機本体１１の搬送レール４０に支持された交換部材を当該搬送レール４０と略同じ高さに位置する収容ラック６０の支持レール６１に送り入れる。なお、収容ラック６０は、作業者により交換装置５０の受け入れ位置まで搬送されてもよいし、自動搬送装置（ＡＧＶ）に搭載されて自動搬送装置によって交換装置５０の受け入れ位置まで自動搬送されてもよい。 As shown in FIG. 1, the storage rack 60 is a storage body that has a pair of left and right support rails 61 in multiple stages, and can store replacement parts on each support rail 61. In addition, openings 62, 63 are formed on the front and rear sides of the storage rack 60, which are located on the printing machine body 11. The replacement parts are inserted and removed by an operator through the opening 62 on the front side, and are carried in and out by the frame front-rear moving unit 54 through the opening 63 on the rear side. When the storage rack 60 is received by the exchange device 50, the frame front-rear moving unit 54 sends the replacement parts supported on the support rails 61 located at approximately the same height as the transport rails 40 of the printing machine body 11 out of the multiple stages of support rails 61 of the storage rack 60 by the rack lifting unit 53 to the printing machine body 11. In addition, the frame front-rear moving unit 54 sends the replacement parts supported on the transport rails 40 of the printing machine body 11 to the support rails 61 of the storage rack 60 located at approximately the same height as the transport rails 40. The storage rack 60 may be transported to the receiving position of the exchange device 50 by an operator, or may be loaded onto an automatic transport vehicle (AGV) and automatically transported to the receiving position of the exchange device 50 by the automatic transport vehicle.
　交換フレーム７０は、スクリーンマスクＭを支持する枠体である。スクリーンマスクＭは、金属製の薄板であり、所定のテンションが付与された状態で交換フレーム７０により支持される。スクリーンマスクＭは、交換フレーム７０に支持されたままの状態で、搬送レール４０上の作業領域で位置決め固定され、印刷に使用される。 The replacement frame 70 is a frame that supports the screen mask M. The screen mask M is a thin metal plate that is supported by the replacement frame 70 with a certain tension applied. While still supported by the replacement frame 70, the screen mask M is positioned and fixed in the working area on the transport rail 40 and used for printing.
　交換フレーム８０は、図４に示すように、基板支持部材３２を支持する枠体であり、交換フレーム７０と略同じ左右幅を有する。交換フレーム８０は、矩形状の外枠８１と、互いに向かい合うように外枠８１に固定されて基板支持部材３２を両側から支持する一対の支持部８２と、カムフォロア８３と、を備える。カムフォロア８３は、外枠８１の左辺部８１ａおよび右辺部８１ｂの内側かつ下面に複数個（例えば４個）ずつ回転可能に支持されている。 As shown in FIG. 4, the replacement frame 80 is a frame that supports the board support member 32 and has approximately the same left-right width as the replacement frame 70. The replacement frame 80 comprises a rectangular outer frame 81, a pair of support parts 82 that are fixed to the outer frame 81 facing each other and support the board support member 32 from both sides, and a cam follower 83. A plurality of cam followers 83 (e.g., four each) are rotatably supported on the inside and underside of the left side part 81a and right side part 81b of the outer frame 81.
　搬送レール４０は、図２，図３に示すように、印刷機本体１１の中段部の通過口３６（図２参照）と略同じ高さに設置され、前後方向（Ｙ軸方向）に延在する左右一対の長尺のレールである。搬送レール４０は、交換フレーム７０（スクリーンマスクＭ）の搬送に用いられる左右一対の第１搬送面４１と、交換フレーム８０（基板支持部材３２）の搬送に用いられる左右一対の第２搬送面４５と、を有する。 As shown in Figures 2 and 3, the transport rails 40 are installed at approximately the same height as the passage opening 36 (see Figure 2) in the middle section of the printer body 11, and are a pair of left and right long rails extending in the front-to-rear direction (Y-axis direction). The transport rails 40 have a pair of left and right first transport surfaces 41 used to transport the replacement frame 70 (screen mask M), and a pair of left and right second transport surfaces 45 used to transport the replacement frame 80 (substrate support member 32).
　左右一対の第１搬送面４１には、それぞれ、前後方向に延在する平坦な搬送面本体４２と、搬送面本体４２に対して前後に所定の間隔をおいて複数個ずつ設けられ搬送面本体４２よりも上方に***した複数の支持部４３と、を有する。すなわち、各第１搬送面４１には、各支持部４３により段差を有する。各支持部４３は、図５に示すように、スクリーンマスクＭの交換フレーム７０（外枠）の下面に当接する当接面を有し、当該当接面によってスクリーンマスクＭを水平姿勢で支持するものである。支持部４３の当接面は、切削加工等によって、良好な平坦精度および高さ精度が確保されている。これにより、搬送面本体４２で交換フレーム７０（外枠）を支持するものに比して、スクリーンマスクＭの平坦度をより容易に確保することができる。また、支持部４３の周囲には、搬送面本体４２よりも凹んだ周状の凹溝４４が形成されている。このため、スクリーンマスクＭを支持する交換フレーム７０が支持部４３を摺動する際に生じた摩耗粉を凹溝４４で受けることができ、摩耗粉が搬送面本体４２や支持部４３に付着するのを抑制することができる。 Each of the pair of left and right first conveying surfaces 41 has a flat conveying surface body 42 extending in the front-rear direction, and a plurality of support parts 43 that are provided at a predetermined interval in front of and behind the conveying surface body 42 and protrude above the conveying surface body 42. That is, each first conveying surface 41 has a step due to each support part 43. As shown in FIG. 5, each support part 43 has an abutment surface that abuts against the lower surface of the replacement frame 70 (outer frame) of the screen mask M, and supports the screen mask M in a horizontal position by the abutment surface. The abutment surface of the support part 43 has good flatness accuracy and height accuracy ensured by cutting processing or the like. This makes it easier to ensure the flatness of the screen mask M compared to when the replacement frame 70 (outer frame) is supported by the conveying surface body 42. In addition, a circumferential groove 44 recessed further than the conveying surface body 42 is formed around the support part 43. As a result, the grooves 44 can receive wear particles generated when the replacement frame 70 supporting the screen mask M slides over the support part 43, preventing the wear particles from adhering to the conveying surface main body 42 and the support part 43.
　左右一対の第２搬送面４５は、それぞれ、左右一対の第１搬送面４１の内側に連続して設けられている。各第２搬送面４５は、図６に示すように、外側の第１搬送面４１（搬送面本体４２）よりも一段低い位置に、前後に延在する段差のない平坦面により形成される。上述したように、交換フレーム８０の外枠８１の左辺部８１ａおよび右辺部８１ｂにおける内側かつ下面には、カムフォロア８３が設けられており、交換フレーム８０は、カムフォロア８３が第２搬送面４５上を転動することで、搬送レール４０に沿って走行する。左右一対の第１搬送面４１（支持部４３）は、図６に示すように、カムフォロア８３が第２搬送面４５上に接触した状態で交換フレーム８０の外枠８１の下面よりも低い位置となるように形成されている。これにより、交換フレーム８０をスムーズに搬送させることができる。 The pair of left and right second conveying surfaces 45 are provided continuously on the inside of the pair of left and right first conveying surfaces 41. As shown in FIG. 6, each second conveying surface 45 is formed by a flat surface without steps extending forward and backward at a position one step lower than the outer first conveying surface 41 (conveying surface main body 42). As described above, cam followers 83 are provided on the inner and lower surface of the left side portion 81a and the right side portion 81b of the outer frame 81 of the exchange frame 80, and the exchange frame 80 runs along the conveying rail 40 by the cam followers 83 rolling on the second conveying surface 45. As shown in FIG. 6, the pair of left and right first conveying surfaces 41 (support portions 43) are formed so that they are lower than the lower surface of the outer frame 81 of the exchange frame 80 when the cam followers 83 are in contact with the second conveying surface 45. This allows the exchange frame 80 to be smoothly conveyed.
　また、左右一対の第２搬送面４５の互いに向かい合う内側の端部には、側壁４６が設けられている。側壁４６は、主として、交換フレーム８０（基板支持部材３２）が第２搬送面４５上を搬送されることに伴って生じる摩耗粉が基板Ｓや基板搬送装置３０等へ落下するのを防止するためのものである。 Furthermore, side walls 46 are provided on the inner ends of the pair of left and right second transport surfaces 45 that face each other. The side walls 46 are primarily intended to prevent wear powder generated when the replacement frame 80 (substrate support member 32) is transported on the second transport surfaces 45 from falling onto the substrate S, substrate transport device 30, etc.
　ここで、スクリーンマスクＭの交換は、以下のようにして行なわれる。すなわち、印刷機１０の制御装置は、まず、プッシャ昇降部２５とヘッド移動部２６とを制御して、スクリーンマスクＭを支持した、第１搬送面４１上の交換フレーム７０をプッシャ２４で押して第１搬送面４１上を移動させ、交換フレーム７０を通過口３６から筐体１２外へ搬出させる。続いて、制御装置は、交換装置５０を制御して、交換フレーム７０を収容ラック６０に回収する。次に、制御装置は、交換装置５０を制御して、新たなスクリーンマスクＭを支持した交換フレーム７０を収容ラック６０から取り出して、通過口３６から筐体１２内へ搬入させる。そして、制御装置は、プッシャ昇降部２５とヘッド移動部２６とを制御して、搬入した交換フレーム７０をプッシャ２４で押して第１搬送面４１上を移動させることで、交換フレーム７０（新たなスクリーンマスクＭ）を作業領域まで搬送して位置決めする。 Here, the replacement of the screen mask M is performed as follows. That is, the control device of the printing machine 10 first controls the pusher lifting unit 25 and the head moving unit 26 to push the replacement frame 70 supporting the screen mask M on the first transport surface 41 with the pusher 24 to move it on the first transport surface 41, and to transport the replacement frame 70 from the passage opening 36 to the outside of the housing 12. Next, the control device controls the replacement device 50 to recover the replacement frame 70 to the storage rack 60. Next, the control device controls the replacement device 50 to remove the replacement frame 70 supporting a new screen mask M from the storage rack 60 and to transport it into the housing 12 from the passage opening 36. Then, the control device controls the pusher lifting unit 25 and the head moving unit 26 to push the transported replacement frame 70 with the pusher 24 to move it on the first transport surface 41, and to transport and position the replacement frame 70 (new screen mask M) to the working area.
　また、必要に応じて基板支持部材３２の交換も行なわれる。基板支持部材３２の交換は、搬送レール４０上のスクリーンマスクＭ（交換フレーム７０）を収容ラック６０に退避させた状態で行なわれる。印刷機１０の制御装置は、交換装置５０を制御して、空の交換フレーム８０を収容ラック６０から取り出して、通過口３６から筐体１２内へ搬入させる。続いて、制御装置は、プッシャ昇降部２５とヘッド移動部２６とを制御して、筐体１２内に搬入した空の交換フレーム８０をプッシャ２４で押して第２搬送面４５上を移動させることで、交換フレーム８０を作業領域まで移動させる。次に、制御装置は、基板支持部材昇降部３３を制御して、基板支持部材３２を上昇させ、基板支持部材３２を第２搬送面４５上の交換フレーム８０へ受け渡す。なお、基板支持部材３２の受け渡しについては、例えば、国際公開第２０１８／１０５０１６号公報に記載の手法を用いることができる。次に、制御装置は、プッシャ昇降部２５とヘッド移動部２６とを制御して、交換フレーム８０をプッシャ２４で押して第２搬送面４５上を移動させ、交換フレーム８０を通過口３６から筐体１２外へ搬出させる。そして、制御装置は、交換装置５０を制御して、交換フレーム８０を収容ラック６０に回収する。次に、制御装置は、交換装置５０を制御して、新たな基板支持部材３２を支持した交換フレーム８０を収容ラック６０から取り出して、通過口３６から筐体１２内へ搬入させる。続いて、制御装置は、プッシャ昇降部２５とヘッド移動部２６とを制御して、筐体１２内に搬入した交換フレーム８０をプッシャ２４で押して第２搬送面４５上を移動させることで、交換フレーム８０（新たな基板支持部材３２）を作業領域まで搬送する。そして、制御装置は、基板支持部材昇降部３３を制御して、基板支持部材３２を上昇させ、新たな基板支持部材３２を基板支持部材昇降部３３に受け渡す。その後、制御装置は、プッシャ昇降部２５とヘッド移動部２６とを制御して、基板支持部材３２を受け渡した後の空の交換フレーム８０をプッシャ２４で押して第２搬送面４５上を移動させ、交換フレーム８０を通過口３６から筐体１２外へ搬出させる。そして、制御装置は、交換装置５０を制御して、空の交換フレーム８０を収容ラック６０に回収する。 In addition, the substrate support member 32 is also replaced as necessary. The substrate support member 32 is replaced in a state where the screen mask M (replacement frame 70) on the transport rail 40 is retracted to the storage rack 60. The control device of the printing machine 10 controls the replacement device 50 to remove the empty replacement frame 80 from the storage rack 60 and carry it into the housing 12 through the passage opening 36. Next, the control device controls the pusher lifting unit 25 and the head moving unit 26 to push the empty replacement frame 80 carried into the housing 12 with the pusher 24 to move it on the second transport surface 45, thereby moving the replacement frame 80 to the working area. Next, the control device controls the substrate support member lifting unit 33 to raise the substrate support member 32 and transfer the substrate support member 32 to the replacement frame 80 on the second transport surface 45. Note that the transfer of the substrate support member 32 can be performed, for example, by using a method described in International Publication No. WO 2018/105016. Next, the control device controls the pusher lifting unit 25 and the head moving unit 26 to push the replacement frame 80 with the pusher 24 to move it on the second transport surface 45, and to transport the replacement frame 80 from the passage opening 36 to the outside of the housing 12. Then, the control device controls the replacement device 50 to recover the replacement frame 80 to the storage rack 60. Next, the control device controls the replacement device 50 to take out the replacement frame 80 supporting the new substrate support member 32 from the storage rack 60, and to transport it into the housing 12 from the passage opening 36. Next, the control device controls the pusher lifting unit 25 and the head moving unit 26 to push the replacement frame 80 brought into the housing 12 with the pusher 24 to move it on the second transport surface 45, and to transport the replacement frame 80 (new substrate support member 32) to the working area. The control device then controls the substrate support member lifting unit 33 to lift the substrate support member 32 and transfer the new substrate support member 32 to the substrate support member lifting unit 33. The control device then controls the pusher lifting unit 25 and the head moving unit 26 to push the empty replacement frame 80 after the substrate support member 32 has been transferred by the pusher 24 to move it on the second transport surface 45, and to transport the replacement frame 80 out of the housing 12 through the passage opening 36. The control device then controls the replacement device 50 to retrieve the empty replacement frame 80 into the storage rack 60.
　このように、本実施形態では、スクリーンマスクＭと基板支持部材３２とは、それぞれ異なる搬送面（第１搬送面４１、第２搬送面４５）を用いて搬送される。このため、搬送面を分散させることができ、摩耗粉の発生を低減させることができる。そして、スクリーンマスクＭの交換の際に、交換フレーム７０と左右一対の第１搬送面４１の各支持部４３との摺動に伴って摩耗粉が発生しても、発生した摩耗粉は、各支持部４３の周囲に形成された凹溝４４に溜められる。このため、搬送面本体４２や支持部４３に摩耗粉が付着し、蓄積するのを抑制することができ、蓄積された摩耗粉に交換フレーム７０が乗り上げて、スクリーンマスクＭの平坦度が低下するのを防止することができる。また、基板支持部材３２の交換フレーム８０は、左右一対の第２搬送面４５上をカムフォロア８３が転動することにより搬送されるため、交換フレーム８０の搬送をスムーズに行なうことができる。さらに、左右一対の第２搬送面４５は、左右一対の第１搬送面４１の内側に第１搬送面４１よりも一段低い位置に設けられるから、交換フレーム８０の搬送に伴って第２搬送面４５に摩耗粉が発生しても、摩耗粉が第１搬送面４１に付着するのを抑制することができる。また、左右一対の第２搬送面４５の互いに向かい合う内側の端部には側壁４６が設けられているから、交換フレーム８０の搬送に伴って第２搬送面４５に摩耗粉が発生しても、発生した摩耗粉が基板搬送装置３０や基板Ｓ上に落下するのを防止することができる。 In this way, in this embodiment, the screen mask M and the substrate support member 32 are transported using different transport surfaces (first transport surface 41, second transport surface 45). Therefore, the transport surfaces can be dispersed, and the generation of wear powder can be reduced. Even if wear powder is generated due to the sliding between the replacement frame 70 and each support part 43 of the pair of left and right first transport surfaces 41 when replacing the screen mask M, the generated wear powder is stored in the grooves 44 formed around each support part 43. Therefore, it is possible to suppress the adhesion and accumulation of wear powder on the transport surface main body 42 and the support parts 43, and it is possible to prevent the replacement frame 70 from riding on the accumulated wear powder and reducing the flatness of the screen mask M. In addition, the replacement frame 80 of the substrate support member 32 is transported by the cam followers 83 rolling on the pair of left and right second transport surfaces 45, so that the replacement frame 80 can be transported smoothly. Furthermore, the pair of left and right second transport surfaces 45 are provided inside the pair of left and right first transport surfaces 41 at a position one step lower than the first transport surfaces 41, so even if wear powder is generated on the second transport surfaces 45 as the replacement frame 80 is transported, the wear powder can be prevented from adhering to the first transport surfaces 41. In addition, since side walls 46 are provided at the inner ends of the pair of left and right second transport surfaces 45 facing each other, even if wear powder is generated on the second transport surfaces 45 as the replacement frame 80 is transported, the generated wear powder can be prevented from falling onto the substrate transport device 30 or the substrate S.
　ここで、実施形態の主要な要素と請求の範囲に記載した本開示の主要な要素との対応関係について説明する。即ち、本実施形態のスクリーンマスクＭや基板支持部材３２が本開示の交換部材に相当し、印刷機１０が印刷機に相当し、第１搬送面４１が第１搬送面に相当し、交換フレーム８０が搬送治具に相当し、第２搬送面４５が第２搬送面に相当する。また、搬送面本体４２が搬送面本体に相当し、支持部４３が支持部に相当する。また、凹溝４４が凹部に相当する。また、カムフォロア８３がカムフォロアに相当する。また、側壁４６が側壁に相当する。 Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure described in the claims will be explained. That is, the screen mask M and the substrate support member 32 of the present embodiment correspond to the replacement member of the present disclosure, the printer 10 corresponds to the printer, the first transport surface 41 corresponds to the first transport surface, the replacement frame 80 corresponds to the transport jig, and the second transport surface 45 corresponds to the second transport surface. Also, the transport surface main body 42 corresponds to the transport surface main body, and the support portion 43 corresponds to the support portion. Also, the recessed groove 44 corresponds to the recess. Also, the cam follower 83 corresponds to the cam follower. Also, the side wall 46 corresponds to the side wall.
　なお、本開示は上述した実施形態に何ら限定されることはなく、本開示の技術的範囲に属する限り種々の態様で実施し得ることはいうまでもない。 It goes without saying that this disclosure is in no way limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of this disclosure.
　例えば、上述した実施形態では、交換フレーム８０は、その外枠８１に設けられたカムフォロア８３が第２搬送面４５上を転動することで搬送されるものとした。しかし、カムフォロア８３を省略し、交換フレーム８０は、第２搬送面４５を摺動することで搬送されてもよい。 For example, in the embodiment described above, the replacement frame 80 is transported by the cam followers 83 provided on the outer frame 81 rolling on the second transport surface 45. However, the cam followers 83 may be omitted, and the replacement frame 80 may be transported by sliding on the second transport surface 45.
　上述した実施形態では、左右一対の第２搬送面４５は、左右一対の第１搬送面４１の内側に設けられたが、左右一対の第１搬送面４１の外側に設けられてもよい。 In the above-described embodiment, the pair of left and right second conveying surfaces 45 are provided inside the pair of left and right first conveying surfaces 41, but they may also be provided outside the pair of left and right first conveying surfaces 41.
　上述した実施形態では、第２搬送面４５は、基板支持部材３２が取り付けられる交換フレーム８０の搬送に用いられるものとした。しかし、第２搬送面４５は、印刷機１０で用いられるものであれば、スクリーンマスクＭ以外の他の交換部材（例えば、スキージ２２）が取り付けられる交換フレーム（搬送治具）の搬送に用いられてもよい。なお、交換部材としてスキージ２２を交換フレームに取り付けて第２搬送面４５上を搬送させた際の、当該スキージ２２のヘッド本体２１への受け渡しについては、例えば、国際公開第２０１８／１０５０１６号公報に記載の手法を用いることができる。 In the above-described embodiment, the second transport surface 45 is used to transport the replacement frame 80 to which the substrate support member 32 is attached. However, the second transport surface 45 may be used to transport a replacement frame (transport jig) to which a replacement member other than the screen mask M (e.g., a squeegee 22) is attached, as long as it is used in the printing machine 10. Note that when the squeegee 22 is attached to the replacement frame as a replacement member and transported over the second transport surface 45, the squeegee 22 can be transferred to the head body 21 using, for example, the method described in WO 2018/105016.
　上述した実施形態では、本開示の印刷機を、対象物としての基板Ｓに粘性流体としてのはんだを印刷するものに適用した。しかし、対象物としては、立体物などの他の基材であってもよく、粘性流体としては、導電性ペーストや接着剤などであってもよい。 In the above-described embodiment, the printer of the present disclosure is applied to printing solder as a viscous fluid on a substrate S as an object. However, the object may be other substrates such as three-dimensional objects, and the viscous fluid may be a conductive paste, adhesive, etc.
　以上説明したように、本開示の印刷機では、スクリーンマスクの搬送とスクリーンマスクとは異なる他の交換部材の搬送とにそれぞれ異なる搬送面（第１搬送面、第２搬送面）を用いることとしている。搬送面を分散させることで、摩耗粉の発生を低減させることができる。この結果、スクリーンマスクやその他の交換部材の交換に際して、経年使用に拘わらず、スクリーンマスクや交換部材が取り付けられた搬送治具の搬送をスムーズに行なうことができる。 As described above, in the printing machine disclosed herein, different transport surfaces (first transport surface, second transport surface) are used for transporting the screen mask and for transporting replacement parts other than the screen mask. By dispersing the transport surfaces, the generation of wear powder can be reduced. As a result, when replacing the screen mask or other replacement parts, the transport jig to which the screen mask or replacement part is attached can be transported smoothly, regardless of long-term use.
　こうした本開示の印刷機において、前記一対の第１搬送面は、段差を有し、前記一対の第２搬送面は、段差を有しないものとしてもよい。こうすれば、第２搬送面での搬送治具の搬送をスムーズに行なうことができる。この場合、前記一対の第１搬送面は、搬送面本体と、前記段差として前記搬送面本体よりも高い位置に***し前記スクリーンマスクを水平姿勢で支持する支持部を有してもよい。こうすれば、支持部の精度を確保することにより、第１搬送面全体の精度を確保することなく、スクリーンマスクの平坦度を良好に維持することができる。さらにこの場合、前記第１搬送面は、前記支持部の周囲に前記搬送面本体よりも凹んだ凹部を有してもよい。第１搬送面を用いてスクリーンマスクを搬送した際に生じる摩耗粉を凹部で受けることができる。 In such a printing machine of the present disclosure, the pair of first conveying surfaces may have a step, and the pair of second conveying surfaces may have no step. In this way, the conveying jig can be smoothly conveyed on the second conveying surfaces. In this case, the pair of first conveying surfaces may have a conveying surface main body and a support portion that is raised as the step at a position higher than the conveying surface main body and supports the screen mask in a horizontal position. In this way, by ensuring the accuracy of the support portion, the flatness of the screen mask can be well maintained without ensuring the accuracy of the entire first conveying surface. Furthermore, in this case, the first conveying surface may have a recess around the support portion that is recessed deeper than the conveying surface main body. The recess can receive wear powder generated when the screen mask is conveyed using the first conveying surface.
　また、本開示の印刷機において、前記一対の第２搬送面は、前記一対の第１搬送面よりも低い位置に設けられてもよい。こうすれば、第２搬送面で搬送治具を搬送した際に生じた摩耗粉がスクリーンマスクを搬送する第１搬送面に付着するのを抑制することができる。 Furthermore, in the printing machine disclosed herein, the pair of second conveying surfaces may be provided at a lower position than the pair of first conveying surfaces. In this way, it is possible to prevent wear powder generated when the conveying jig is conveyed on the second conveying surfaces from adhering to the first conveying surface that conveys the screen mask.
　また、本開示の印刷機において、前記搬送治具には、前記第２搬送面上を転動するカムフォロアが設けられ、前記一対の第１搬送面は、前記カムフォロアが前記第２搬送面に接した状態において前記搬送治具の枠の底面よりも低い位置に設けられてもよい。こうすれば、搬送治具の搬送をスムーズに行なうことができる。 Furthermore, in the printing machine disclosed herein, the transport jig may be provided with cam followers that roll on the second transport surface, and the pair of first transport surfaces may be provided at a position lower than the bottom surface of the frame of the transport jig when the cam followers are in contact with the second transport surface. In this way, the transport jig can be transported smoothly.
　また、本開示の印刷機において、前記一対の第２搬送面は、前記一対の第１搬送面の内側に連続して設けられ、前記一対の第２搬送面の互いに向かい合う側の端部には、側壁が設けられてもよい。こうすれば、第２搬送面を用いて搬送治具を搬送した際に生じる摩耗粉を落下させないようにすることができる。 Furthermore, in the printing machine disclosed herein, the pair of second conveying surfaces may be provided contiguous to the inside of the pair of first conveying surfaces, and side walls may be provided at the ends of the pair of second conveying surfaces facing each other. In this way, it is possible to prevent wear powder generated when the conveying jig is conveyed using the second conveying surfaces from falling.
