Description

本発明は、電子部品等の微小な物品を搬送して供給する装置に関する。   The present invention relates to an apparatus for conveying and supplying a minute article such as an electronic component.

プリント基板に実装される電子部品の供給に、テープリール式フィーダーが利用されている。これは、合成樹脂や紙製のテープに１〜２ｍｍ間隔で窪みを形成し、電子部品をその窪みに収容して、実装機（マウンター）に供給する装置である。しかし、テープリール式フィーダーには、テープが嵩張るため装置が大きくなることや、使用後にテープが廃棄物になるという問題があった。   A tape reel type feeder is used to supply electronic components mounted on a printed circuit board. This is a device that forms depressions in a synthetic resin or paper tape at intervals of 1 to 2 mm, accommodates electronic components in the depressions, and supplies them to a mounting machine (mounter). However, the tape reel type feeder has a problem that the tape becomes bulky and the apparatus becomes large, and the tape becomes waste after use.

この問題に対して、テープを用いないバルクフィーダーが開発された。これは、電子部品をホッパーに投入し、ホッパー下部からトンネル状の搬送路に導き、１列に整列させて、気流によってマウンターへ搬送、供給するものである。搬送路末端に設けられた取出口に到達した電子部品は、マウンターのピックアップノズルに吸着されて順次取り出される。例えば、特許文献１には、カセットにランダムに収納された角形のチップをトンネル内に送り込み、トンネルの先端部側（下流側）を真空吸引することによりチップを搬送するバルクフィーダーが記載されている。   In response to this problem, bulk feeders that do not use tape have been developed. In this method, electronic parts are put into a hopper, guided from the lower part of the hopper to a tunnel-like conveyance path, aligned in a line, and conveyed and supplied to the mounter by an air current. The electronic components that have reached the take-out port provided at the end of the transport path are adsorbed by the pick-up nozzle of the mounter and sequentially taken out. For example, Patent Document 1 describes a bulk feeder that transports chips by feeding rectangular chips randomly stored in a cassette into a tunnel and vacuum-sucking the tip side (downstream side) of the tunnel. .

特開平１０−２９４５９７号公報JP-A-10-294597

しかしながら、本発明者らの研究によって、従来のバルクフィーダーには供給速度の向上に課題があることが明らかになった。マウンターのピックアップノズルによる取り出しの時間間隔（ピッチ）を短くすると、電子部品の取り出しに失敗する確率が高くなったのである。この原因は、搬送自体の速度が遅いことではなく、搬送路の下流端から取り出そうとする電子部品が後続の電子部品と干渉することであった。すなわち、搬送路を整列して搬送されてきた電子部品が、次々と下流端に到達して隙間なく列を成しており、先頭の１個を取り出す際に、次の電子部品が引っ掛って取り出しの邪魔をすることが分かった。   However, studies by the present inventors have revealed that the conventional bulk feeder has a problem in improving the supply speed. If the time interval (pitch) for picking up by the pick-up nozzle of the mounter was shortened, the probability of failing to pick up the electronic component increased. The cause is not that the speed of the conveyance itself is slow, but that an electronic component to be taken out from the downstream end of the conveyance path interferes with a subsequent electronic component. In other words, the electronic components that have been transported in alignment on the transport path reach the downstream end one after another and form a line without a gap, and when the first one is taken out, the next electronic component is caught. I found out that it would interfere with the removal.

本発明は、上記を考慮してなされたものであり、微小な物品を搬送し、高速で１個ずつ供給可能な供給装置を提供することを目的とする。   The present invention has been made in consideration of the above, and an object of the present invention is to provide a supply device that can transport a minute article and supply one by one at a high speed.

上記目的のために、本発明の供給装置は、搬送路の下流端で、先頭の搬送物だけを分離して、側方に設けられた取出口に移動させる。   For the above purpose, the supply device of the present invention separates only the leading transported object at the downstream end of the transport path, and moves it to the outlet provided on the side.

本発明の物品供給装置は、一次元方向に延在する搬送路と、前記搬送路の上流側から下流側に向けて搬送物を搬送する搬送機構と、前記搬送路の下流端に連通する受入位置で、前記搬送物の１個を収容可能な収容部を有する可動ブロックと、前記受入位置の側方に設けられた前記搬送物の取出口とを有する。そして、前記収容部が前記受入位置と前記取出口との間を移動するように、前記可動ブロックが往復運動可能である。   The article supply apparatus according to the present invention includes a conveyance path extending in a one-dimensional direction, a conveyance mechanism that conveys a conveyance object from an upstream side to a downstream side of the conveyance path, and a reception that communicates with a downstream end of the conveyance path. A movable block having a receiving portion capable of accommodating one of the conveyed objects at a position, and an outlet of the conveyed object provided at a side of the receiving position. And the said movable block can reciprocate so that the said accommodating part may move between the said receiving position and the said outlet.

好ましくは、前記搬送機構は、前記搬送路の上流に設けられた送気部および／または前記搬送路の下流に設けられた吸気部である。   Preferably, the transport mechanism is an air supply section provided upstream of the transport path and / or an intake section provided downstream of the transport path.

好ましくは、前記物品供給装置は前記可動ブロックの可動領域の両端に加減圧部をさらに有し、前記可動ブロックが前記加減圧部によって生じる気圧差によって往復運動可能である。   Preferably, the article supply device further includes a pressure increasing / decreasing portion at both ends of the movable region of the movable block, and the movable block can reciprocate due to a pressure difference generated by the pressure increasing / decreasing portion.

好ましくは、前記可動ブロックは位置決め機構をさらに有し、前記位置決め機構は、前記収容部に収容した前記搬送物を該収容部の側壁面に位置決め可能である。   Preferably, the movable block further includes a positioning mechanism, and the positioning mechanism is capable of positioning the transported object accommodated in the accommodating portion on a side wall surface of the accommodating portion.

さらに好ましくは、前記位置決め機構は、前記収容部の前記取出口側の側壁面に設けられ、前記加減圧部のうち前記取出口側にある加減圧部と連通している固定用通気部である。   More preferably, the positioning mechanism is a fixing ventilation portion that is provided on a side wall surface on the outlet side of the housing portion and communicates with a pressure increasing / decreasing portion on the outlet side of the pressure increasing / decreasing portion. .

また、好ましくは、前記収容部の前記搬送路方向の長さ（Ｄ）と、前記収容部と前記搬送路下流端との間隙（Ｇ）との和（Ｄ＋Ｇ）が、搬送物の前記搬送路方向の標準長さ（ＬＳ）より長い。 Preferably, the sum (D + G) of the length (D) of the accommodating portion in the conveying path direction and the gap (G) between the accommodating portion and the downstream end of the conveying path is the conveying path of the conveyed product. It is longer than the standard length of the direction (L S ).

また、好ましくは、搬送物が電子回路基板に実装される電子部品である。   Preferably, the conveyed product is an electronic component mounted on an electronic circuit board.

本発明の物品供給装置によれば、搬送路の下流端に到達した搬送物の列から、可動ブロックにより、先頭の１個だけを分離して取出口に移動させることができる。その結果、取り出しのピッチを速くしても、後続の搬送物との干渉がない状態で、分離した搬送物を取り出すことができる。   According to the article supply apparatus of the present invention, it is possible to separate only the first one from the row of conveyed items that have reached the downstream end of the conveying path and move it to the outlet by the movable block. As a result, even if the picking pitch is increased, the separated transported object can be taken out without interference with the subsequent transported object.

本発明の一実施形態である物品供給装置を図に基づいて説明する。なお、各図は、説明を容易にするために、縮尺が正確ではなく、部材間の隙間等が誇張して描かれている。   An article supply apparatus according to an embodiment of the present invention will be described with reference to the drawings. In addition, in each figure, in order to demonstrate easily, the reduced scale is not accurate and the gap | interval etc. between members are exaggerated and drawn.

図１および図２において、本実施形態の物品供給装置１０は、ホッパー７０と組み合わされて、マウンターに電子部品６０を搬送、供給する。搬送物である電子部品は、ホッパーに投入される。電子部品は、ホッパー下部から供給装置１０の搬送路２０に導かれる。電子部品は、その長手方向を搬送路の方向に向けて、一列に整列して、搬送路内を気流によって下流へと搬送される。電子部品は、搬送路の下流端に設けられた可動ブロック３０によって、搬送路下流端の側方に設けられた取出口５０に移動し、マウンターのピックアップノズル８０に吸着されて取り出される。   1 and 2, the article supply apparatus 10 according to the present embodiment is combined with a hopper 70 to convey and supply an electronic component 60 to a mounter. The electronic component which is a conveyed product is thrown into a hopper. The electronic component is guided to the conveyance path 20 of the supply device 10 from the lower part of the hopper. The electronic components are aligned in a line with the longitudinal direction thereof in the direction of the transport path, and are transported downstream in the transport path by airflow. The electronic component is moved to the take-out port 50 provided at the side of the downstream end of the transport path by the movable block 30 provided at the downstream end of the transport path, and is picked up and taken out by the pickup nozzle 80 of the mounter.

本実施形態の電子部品６０は、略直方体形状を有する。電子部品の大きさは特に限定されない。しかし、電子部品が大きい場合は、電子部品同士の干渉の影響が相対的に小さくなり、本実施形態の供給装置を利用する意義が小さくなる。このことから、電子部品の大きさは略直方体形状の長辺が２０ｍｍ以下であることが好ましく、５ｍｍ以下であることがより好ましく、２ｍｍ以下であることが特に好ましい。さらに、本実施形態の供給装置は、規格サイズである３２１６サイズ（３．２ｍｍ×１．６ｍｍ×１．６ｍｍ）、２０１２サイズ（２．０ｍｍ×１．２ｍｍ×１．２ｍｍ）、１６０８サイズ（１．６ｍｍ×０．８ｍｍ×０．８ｍｍ）、１００５サイズ（１．０ｍｍ×０．５ｍｍ×０．５ｍｍ）、０６０３サイズ（０．６ｍｍ×０．３ｍｍ×０．３ｍｍ）、０４０２サイズ（０．４ｍｍ×０．２ｍｍ×０．２ｍｍ）、０２０１サイズ（０．２５ｍｍ×０．１２５ｍｍ×０．１２５ｍｍ）などの積層セラミックコンデンサ（ＭＬＣＣ）に対して好適に用いることができる。一方、電子部品が小さすぎると装置の加工や製作が難しくなるので、電子部品の大きさは、長辺が０．０５ｍｍ以上、短辺が０．０１ｍｍ以上であることが好ましい。   The electronic component 60 of this embodiment has a substantially rectangular parallelepiped shape. The size of the electronic component is not particularly limited. However, when the electronic component is large, the influence of interference between the electronic components is relatively small, and the significance of using the supply device of the present embodiment is reduced. For this reason, the size of the electronic component is preferably 20 mm or less, more preferably 5 mm or less, and particularly preferably 2 mm or less, as long sides of a substantially rectangular parallelepiped shape. Further, the supply device of the present embodiment is a standard size 3216 size (3.2 mm × 1.6 mm × 1.6 mm), 2012 size (2.0 mm × 1.2 mm × 1.2 mm), 1608 size (1 .6 mm x 0.8 mm x 0.8 mm), 1005 size (1.0 mm x 0.5 mm x 0.5 mm), 0603 size (0.6 mm x 0.3 mm x 0.3 mm), 0402 size (0.4 mm × 0.2 mm × 0.2 mm), 0201 size (0.25 mm × 0.125 mm × 0.125 mm) and other multilayer ceramic capacitors (MLCC) can be suitably used. On the other hand, if the electronic component is too small, it becomes difficult to process and manufacture the apparatus. Therefore, the electronic component preferably has a long side of 0.05 mm or more and a short side of 0.01 mm or more.

図３および図４において、搬送路２０は、ベース部材２３に形成された溝と、その溝の上面を覆うカバー部材２２によって、トンネル状に形成されている。トンネルの断面は電子部品６０よりわずかに大きい。微小な物品を高速に搬送するためには、このように側面および上下面が規制された閉鎖系の搬送路を構成することが好ましい。   3 and 4, the transport path 20 is formed in a tunnel shape by a groove formed in the base member 23 and a cover member 22 that covers the upper surface of the groove. The cross section of the tunnel is slightly larger than the electronic component 60. In order to convey a minute article at high speed, it is preferable to form a closed conveyance path in which the side surface and the upper and lower surfaces are regulated as described above.

搬送路２０の上流には送気部（図６の２７）が、下流には吸気部２８が設けられている。送気部は搬送路内に空気を送り込む。吸気部は搬送路内から空気を吸引する。本実施形態の吸気部２８は搬送路の下流端２６から搬送路内の空気を吸引する。送気部および吸気部によって搬送路内を上流から下流に向かう気流を発生させることができる。なお、気流を発生させるためには、搬送路上流の送気部および搬送路下流の吸気部のうち、少なくとも一方が設けられていればよく、その場合他方に通気部を設ければよい。また、搬送路が長い場合は、搬送路の途中に吸気部と送気部を適宜追加して設けてもよい。   An air supply section (27 in FIG. 6) is provided upstream of the conveyance path 20, and an intake section 28 is provided downstream. The air supply unit sends air into the conveyance path. The intake section sucks air from the inside of the conveyance path. The intake section 28 of the present embodiment sucks air in the conveyance path from the downstream end 26 of the conveyance path. An air flow from the upstream to the downstream can be generated in the conveyance path by the air supply unit and the intake unit. In order to generate the airflow, it is sufficient that at least one of the air supply section upstream of the transport path and the intake section downstream of the transport path is provided, and in that case, a ventilation section may be provided in the other. In addition, when the conveyance path is long, an intake part and an air supply part may be appropriately added in the middle of the conveyance path.

図５および図６において、搬送路２０の下流端２６には、可動ブロック３０が配置されている。可動ブロックは、水平面内で搬送路と直角に交差する方向（図５の左右方向、図６の上下方向）に移動可能であり、搬送路下流端と搬送路下流端の側方に設けられた取出口５０の間を往復運動可能である。取出口上部のカバー部材２２には開口があり、開口には開閉可能なシャッター５１が設けられている。可動ブロック３０の可動領域３４は、ベース部材２３と底部部材２４によって形成された空洞によって規定される。可動領域３４の両端には、加減圧部３５、３６が設けられている。なお、シャッター５１は必須ではなく、取出口は常時開放としてもよい。   5 and 6, a movable block 30 is disposed at the downstream end 26 of the conveyance path 20. The movable block is movable in a direction perpendicular to the conveyance path (horizontal direction in FIG. 5 and vertical direction in FIG. 6) in a horizontal plane, and is provided on the side of the conveyance path downstream end and the conveyance path downstream end. A reciprocating motion is possible between the outlets 50. The cover member 22 at the upper part of the outlet has an opening, and a shutter 51 that can be opened and closed is provided in the opening. The movable area 34 of the movable block 30 is defined by a cavity formed by the base member 23 and the bottom member 24. At both ends of the movable region 34, pressure increasing / decreasing portions 35 and 36 are provided. The shutter 51 is not essential, and the outlet may be always open.

可動ブロック３０は上面に、電子部品１個を収容可能な溝状の収容部３１を有する。収容部３１は両側面および上下面が規制された閉鎖系の収容部であるため、収容部３１に電子部品６０を収容した状態で可動ブロックを高速に駆動させたとしても、収容部内の電子部品が収容部外へ飛び出すことなく安定して電子部品を移動可能である。可動ブロックが往復運動の一方の端（図５の右側、図６の上側）にあるときは、収容部が搬送路２０の延長となって、搬送路下流端２６に到達した電子部品の１個を受け入れることができる。以下この状態を、可動ブロックまたは収容部が受入位置にある、という。   The movable block 30 has a groove-shaped accommodation part 31 on the upper surface that can accommodate one electronic component. Since the accommodating part 31 is a closed type accommodating part in which both side surfaces and upper and lower surfaces are regulated, even if the movable block is driven at a high speed while the electronic part 60 is accommodated in the accommodating part 31, the electronic component in the accommodating part Can stably move the electronic component without jumping out of the housing portion. When the movable block is at one end of the reciprocating motion (the right side in FIG. 5 and the upper side in FIG. 6), one of the electronic components that has reached the downstream end 26 of the transport path by the accommodating portion being an extension of the transport path 20 Can accept. Hereinafter, this state is referred to as the movable block or the accommodating portion being in the receiving position.

可動ブロック３０が往復運動の他方の端（図５の左側、図６の下側）にあるときは、収容部３１に収容された電子部品が取出口５０に位置し、上部のシャッター５１を開けて、マウンターのピックアップノズルにより電子部品を取り出すことができる。以下この状態を、可動ブロックまたは収容部が取出位置にある、という。   When the movable block 30 is at the other end of the reciprocating motion (the left side in FIG. 5 and the lower side in FIG. 6), the electronic component accommodated in the accommodating portion 31 is located at the outlet 50 and the upper shutter 51 is opened. Thus, the electronic component can be taken out by the pick-up nozzle of the mounter. Hereinafter, this state is referred to as the movable block or the accommodating portion being in the take-out position.

可動ブロック３０は、上面の収容部３１に対して取出口５０と反対側に、搬送用通気部３２が形成されている。搬送用通気部は、可動ブロックが取出位置にあるときに、搬送路下流端２６と吸気部２８を連通するとともに、搬送路下流端２６に到達した電子部品を堰き止めることができる形状であればよい。   In the movable block 30, a conveying ventilation portion 32 is formed on the side opposite to the outlet 50 with respect to the accommodation portion 31 on the upper surface. The conveying vent may be configured to communicate with the downstream end 26 of the conveyance path and the air intake 28 when the movable block is at the take-out position and to block the electronic component that has reached the downstream end 26 of the conveyance path. Good.

また、可動ブロック３０は、電子部品の位置決め機構として、収容部３１の取出口側の壁面に固定用通気部３３を有する。固定用通気部は、取出口側の加減圧部３５と連通している。   In addition, the movable block 30 has a fixing ventilation portion 33 on the wall surface on the outlet side of the accommodating portion 31 as an electronic component positioning mechanism. The fixing ventilation portion communicates with the pressure increasing / decreasing portion 35 on the outlet side.

図７に、可動ブロック３０の収容部３１付近を拡大して示す。図７Ａにおいて、可動ブロックが受入位置にあるとき、収容部３１は搬送路２０と連通して搬送路の延長となり、電子部品の１個を受け入れ可能である。収容部の搬送路方向の長さＤと電子部品の搬送路方向の標準長さＬＳとの関係は通常Ｄ≦ＬＳである。なお、収容部の搬送路方向の長さＤが電子部品の搬送路方向の標準長さＬＳと等しいと、これより短い電子部品が混入していた場合に、後続の電子部品の先端が収容部内に進入し、可動ブロックを取出位置に移動させる際に干渉する。したがって、収容部の長さＤは、電子部品の搬送路方向の標準長さＬＳより短いことが好ましい。これにより、図７Ｂを参照して、収容部に収容された電子部品６１の長さＬが標準長さＬＳより短い場合でも、後続の電子部品６２の先端が収容部内に入り込むことがなく、可動ブロックの移動を妨げない。具体的には、収容部の長さＤは、ＬＳ×０．９９以下であることが好ましく、ＬＳ×０．９５以下であることがさらに好ましい。一方、収容部が短すぎると、収容した電子部品が安定しないので、収容部の長さＤは、ＬＳ×０．６以上であることが好ましく、０．７以上であることがさらに好ましい。 FIG. 7 shows an enlarged view of the vicinity of the accommodating portion 31 of the movable block 30. In FIG. 7A, when the movable block is in the receiving position, the accommodating portion 31 communicates with the conveyance path 20 and becomes an extension of the conveyance path, and can accept one of the electronic components. Relationship between the standard length L S of the conveying path direction of length D and the electronic components of the transport path direction of the housing portion is generally D ≦ L S. Incidentally, the length D of the conveying path direction of the housing portion is equal to the standard length L S of the conveying path direction of the electronic component, when the shorter electronic component which was contaminated, the tip of the subsequent electronic components housed Interference occurs when entering the part and moving the movable block to the removal position. Therefore, it is preferable that the length D of the accommodating portion is shorter than the standard length L S in the conveyance path direction of the electronic component. Thus, with reference to FIG. 7B, the length L of the electronic component 61 accommodated in the accommodating portion even shorter than the standard length L S, without leading end of the subsequent electronic component 62 enters the receptacle, Does not obstruct the movement of the movable block. Specifically, the length D of the accommodating portion is preferably L S × 0.99 or less, and more preferably L S × 0.95 or less. On the other hand, if the accommodating portion is too short, the accommodated electronic component is not stable. Therefore, the length D of the accommodating portion is preferably L S × 0.6 or more, and more preferably 0.7 or more.

また、収容部３１と搬送路下流端２６の間には間隙Ｇが設けられている。収容部の長さＤと間隙Ｇの和Ｄ＋Ｇは、電子部品の標準長さＬＳより長いことが好ましい。これにより、図７Ｃを参照して、収容部に収容された電子部品６１の長さＬが標準長さＬＳより長い場合でも、可動ブロックを取出位置に移動させる際に、当該電子部品６１が搬送路下流端に引っ掛ることがない。具体的には、収容部の長さＤと間隙Ｇの和Ｄ＋Ｇは、ＬＳ×１．０１以上であることが好ましく、ＬＳ×１．０５以上であることがさらに好ましい。一方、間隙Ｇが大きすぎると、電子部品が搬送路から収容部に移動する際に間隙にひっかかることがあるので、間隙ＧはＬＳ×０．３以下であることが好ましく、ＬＳ×０．２以下であることがさらに好ましい。例えば、Ｇ≦ＬＳ×０．３のとき、Ｄ＝ＬＳ×０．８であればＤ＋Ｇ≦ＬＳ×１．１となり、Ｄ＝ＬＳ×０．９であればＤ＋Ｇ≦ＬＳ×１．２となる。これは実際の寸法でいうと、例えば標準長さＬＳ＝１．０ｍｍのとき、Ｄ＝０．９ｍｍ、Ｇ＝０．３ｍｍとなり、Ｄ＋Ｇ＝１．２ｍｍとなる。 Further, a gap G is provided between the accommodating portion 31 and the transport path downstream end 26. The sum D + G of length D and the gap G of the accommodating portion is preferably longer than the standard length L S of the electronic component. Thus, with reference to FIG. 7C, even when the length L of the electronic component 61 accommodated in the accommodating portion is longer than the standard length L S, when moving the movable block to the removal position, is the electronic component 61 It does not get caught at the downstream end of the conveyance path. Specifically, the sum D + G of the length D of the accommodating portion and the gap G is preferably L S × 1.01 or more, and more preferably L S × 1.05 or more. On the other hand, if the gap G is too large, the electronic component may get caught in the gap when moving from the conveyance path to the accommodating portion. Therefore, the gap G is preferably L S × 0.3 or less, and L S × 0 More preferably, it is 2 or less. For example, when G ≦ L S × 0.3, if D = L S × 0.8, D + G ≦ L S × 1.1, and if D = L S × 0.9, D + G ≦ L S × 1.2. In terms of actual dimensions, for example, when the standard length L S = 1.0 mm, D = 0.9 mm, G = 0.3 mm, and D + G = 1.2 mm.

次に本実施形態の可動ブロックの動作を説明する。   Next, the operation of the movable block of this embodiment will be described.

図８Ａにおいて、可動ブロック３０は、受入位置にある。電子部品は、気流によって搬送されて下流端に到達し、先頭の電子部品６１が可動ブロックの収容部３１に受け入れられる。   In FIG. 8A, the movable block 30 is in the receiving position. The electronic component is conveyed by the airflow and reaches the downstream end, and the leading electronic component 61 is received in the accommodating portion 31 of the movable block.

次いで、図８Ｂにおいて、取出口側の加減圧部（図５および図６の３５）から可動領域（図５の３４）内の空気を吸引し、搬送路側の加減圧部（図５および図６の３６）から可動領域内に送気することによって、可動ブロック３０が受入位置から取出位置に向けて移動する。このとき、収容部内の電子部品６１は、側壁面に設けられた固定用通気部３３が加減圧部３５と連通しているので、固定用通気部に吸い付けられて側壁面に固定（位置決め）される。   Next, in FIG. 8B, the air in the movable region (34 in FIG. 5) is sucked from the pressure increasing / decreasing unit (35 in FIGS. 5 and 6) on the outlet side, and the pressure increasing / decreasing unit (FIGS. 5 and 6 on the transport path side). 36), the movable block 30 moves from the receiving position toward the take-out position. At this time, the electronic component 61 in the housing portion is fixed to the side wall surface by being sucked by the fixing vent portion because the fixing vent portion 33 provided on the side wall surface communicates with the pressure-increasing / decreasing portion 35. Is done.

次いで、図８Ｃにおいて、可動ブロック３０は、取出位置に達する。電子部品６１は固定用通気部３３に吸いつけられている。取出口５０上部のシャッター（図５の４１）が開いて、電子部品６１がマウンターのピックアップノズルによって取り出される。一方、搬送路２０は搬送用通気部３２を介して吸気部２８と連通しているので、搬送路上の電子部品は下流に向かって移動を続け、後続の電子部品６２は可動ブロックに堰き止められて列をなす。   Next, in FIG. 8C, the movable block 30 reaches the extraction position. The electronic component 61 is sucked by the fixing ventilation portion 33. The shutter (41 in FIG. 5) at the upper part of the outlet 50 is opened, and the electronic component 61 is taken out by the pick-up nozzle of the mounter. On the other hand, since the transport path 20 communicates with the intake section 28 via the transport vent 32, the electronic components on the transport path continue to move downstream, and the subsequent electronic components 62 are blocked by the movable block. Form a line.

次いで、図８Ｂと逆に、搬送路側の加減圧部（図５および図６の３６）から可動領域内の空気を吸引し、取出口側の加減圧部（図５および図６の３５）から可動領域内に送気することによって、可動ブロック３０は取出位置から受入位置へと戻る（図８Ａ）。   Next, conversely to FIG. 8B, air in the movable region is sucked from the pressure increasing / decreasing portion (36 in FIGS. 5 and 6) on the conveyance path side, and from the pressure increasing / decreasing portion (35 in FIGS. 5 and 6) on the outlet side. By supplying air into the movable region, the movable block 30 returns from the take-out position to the receiving position (FIG. 8A).

上記の動作を繰り返し行い、搬送路の下流端に到達した搬送物の列から先頭の１個だけを次々に分離（１個切り）して取出口に移動させることで、ピックアップノズルに電子部品を１個ずつ供給することができる。   The above operation is repeated, and only the top one is separated (cut one piece) from the line of the conveyed product that has reached the downstream end of the conveyance path and moved to the take-out port, so that the electronic component is placed in the pickup nozzle. One by one can be supplied.

本実施形態の供給装置の効果を以下に説明する。   The effect of the supply apparatus of this embodiment is demonstrated below.

先に述べたように、従来のバルクフィーダーでは、搬送路下流端の取出口に到達した電子部品が隙間なく列をなした状態で先頭の１個を取り出すため、後続の電子部品との干渉によって、取り出しに失敗することがあった。これに対して、本実施形態の供給装置では、図８に示したように、搬送路下流端で列をなした電子部品のうち、先頭の１個の電子部品６１を可動ブロックによって分離して取出口に移動させるため、取り出しに際して後続の電子部品６２との干渉がない。その結果、取り出しのピッチを短くしても失敗が起こりにくく、単位時間あたりの電子部品の供給数を多くすることができる。本発明者らの実験では、１００５サイズのＭＬＣＣを２０ｍｓ／個程度の速度でマウンターに供給することができた。   As described above, in the conventional bulk feeder, the electronic component that has reached the take-out port at the downstream end of the transport path is taken out in a row without any gaps. , There was a failure to take out. On the other hand, in the supply device of this embodiment, as shown in FIG. 8, among the electronic components arranged in a row at the downstream end of the transport path, the leading one electronic component 61 is separated by a movable block. Since it is moved to the take-out port, there is no interference with the subsequent electronic component 62 during take-out. As a result, even if the picking pitch is shortened, the failure is unlikely to occur, and the number of electronic components supplied per unit time can be increased. In our experiments, 1005 size MLCC could be supplied to the mounter at a rate of about 20 ms / piece.

また、固定用通気部３３の作用により可動ブロックの収容部内で電子部品を固定するので、取出口における電子部品の位置精度を向上させることができる。収容部３１の幅（図８において上下方向の長さ）は電子部品の大きさに対して僅かにクリアランスを設けてあるが、固定用通気部によって電子部品を取出口側の壁面に位置決めすることで、収容部内の電子部品の位置変動を低減し、ピックアップの成功率を高める効果がある。このことは、電子部品のサイズが小さい場合に特に有益である。本発明者らの実験では、１００５サイズの電子部品を位置精度±３０μｍ以内でマウンターに供給することができた。   Further, since the electronic component is fixed in the movable block housing portion by the action of the fixing ventilation portion 33, the positional accuracy of the electronic component at the outlet can be improved. The width of the accommodating portion 31 (length in the vertical direction in FIG. 8) is slightly clearanceed with respect to the size of the electronic component, but the electronic component is positioned on the wall on the outlet side by the fixing ventilation portion. Thus, there is an effect of reducing the position fluctuation of the electronic component in the housing portion and increasing the success rate of the pickup. This is particularly beneficial when the size of the electronic component is small. In our experiments, 1005 size electronic components could be supplied to the mounter with a positional accuracy within ± 30 μm.

また、可動ブロックの移動と、固定用通気部への電子部品の固定の両方が、加減圧部の作動によって実現されるので、両者の同期制御が不要となり、取り出しのピッチが短くなっても一連の動作を安定して行うことができる。   In addition, since both the movement of the movable block and the fixing of the electronic components to the fixing ventilation section are realized by the operation of the pressure-increasing / decreasing section, the synchronization control of both is unnecessary, and even if the picking pitch is shortened, Can be stably performed.

本発明は上記の実施形態に限られるものではなく、その技術的思想の範囲内で種々の変形が可能である。   The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the technical idea.

例えば、搬送物は電子部品には限られない。また、搬送物の形状は略直方体には限られず、搬送物に合わせて搬送路の断面形状を設計することにより気流で搬送可能な形状であればよい。   For example, the conveyed product is not limited to an electronic component. Moreover, the shape of a conveyed product is not restricted to a substantially rectangular parallelepiped, What is necessary is just a shape which can be conveyed with an airflow by designing the cross-sectional shape of a conveyance path according to a conveyed product.

また、例えば、搬送機構は、搬送物を磁石や振動で搬送するものであってもよい。また、可動ブロックの収容部に収容した搬送物を、収容部の側壁面に位置決めする位置決め機構は、磁石で搬送物を側壁面に吸着するものであってもよい。   Further, for example, the transport mechanism may transport the transported object with a magnet or vibration. Further, the positioning mechanism that positions the conveyed product accommodated in the accommodating portion of the movable block on the side wall surface of the accommodating portion may be configured to attract the conveyed item to the side wall surface with a magnet.
