Description

本発明は振動式搬送装置に係り、特に、部品を搬送体の振動により搬送するためのパーツフィーダとして好適な装置構成に関する。   The present invention relates to a vibration type conveying apparatus, and more particularly to an apparatus configuration suitable as a parts feeder for conveying parts by vibration of a conveying body.

一般に、振動式搬送装置は、支持体と、該支持体の上方に配置される搬送体の間に電磁式もしくは圧電式の加振体を連結し、搬送体を搬送方向に見て前後に振動させることで、電子部品等の各種部品を搬送方向に移動させるように構成される。   In general, a vibration-type transfer device has an electromagnetic or piezoelectric vibrator connected between a support and a transfer body disposed above the support, and vibrates back and forth when the transfer body is viewed in the transfer direction. By doing so, various components such as electronic components are configured to move in the transport direction.

このような従来の振動式搬送装置としては、例えば以下の特許文献１に示すように、搬送体の前後２箇所に圧電体と弾性ばねを含む加振体を連結し、これらの加振体の振動方向を搬送方向の前方へ斜め上方に向かうように構成することで、搬送体上に配置された部品を搬送方向へ導くように構成される。
特開２００７−１３７６７４号公報 As such a conventional vibratory conveying device, for example, as shown in Patent Document 1 below, a vibrating body including a piezoelectric body and an elastic spring is connected to two places before and after the conveying body. By configuring the vibration direction to be obliquely upward toward the front in the transport direction, the component disposed on the transport body is configured to be guided in the transport direction.
JP 2007-137664 A

しかしながら、前述の振動式搬送装置においては、加振体の動力源として圧電体を用いる場合、搬送方向の前後に配置された複数の加振体の動作態様を整合させて搬送体を駆動する必要があるので、加振体間の動作調整が必要になるとともに、複数の加振体の相互作用により効率的な駆動ができないため、高いレベルで搬送性能の向上と消費電力の低減を両立させることができないという問題点があった。   However, in the above-described vibratory transfer device, when a piezoelectric body is used as a power source for the vibrating body, it is necessary to match the operation modes of a plurality of vibrating bodies arranged before and after the transfer direction to drive the transfer body. Therefore, it is necessary to adjust the motion between the vibrators, and because it cannot be driven efficiently due to the interaction of multiple vibrators, it is necessary to achieve both high levels of conveyance performance and low power consumption. There was a problem that could not.

そこで、本発明は上記問題点を解決するものであり、その課題は、加振体間の動作調整が不要で、効率的な搬送態様を実現できる振動式搬送装置を提供することにある。   Therefore, the present invention solves the above-described problems, and an object of the present invention is to provide a vibratory transfer device that does not require operation adjustment between vibrating bodies and can realize an efficient transfer mode.

斯かる実情に鑑み、本発明の振動式搬送装置は、支持体（１，１′，７）と、該支持体の上方に加振体（３，４，５，６）を介して配置される搬送体（２，２′）とを具備する振動式搬送装置において、前記加振体は、前記支持体の支持部位（１ａ′）に上端が接続され、該支持部位から下方に伸びる圧電体（３）と、該圧電体の下端に接続されて前記圧電体よりも搬送方向の後方において上方へ伸び、第１の位置（２ａ′）において前記搬送体に連結された第１の弾性体（４）と、前記第１の位置よりも搬送方向の前方に位置する第２の位置（２ｂ′，１ｂ′）において前記搬送体と前記支持体とを直接に連結する第２の弾性体（５）とを含み、前記圧電体と前記第１の弾性体の連結部（６）が自由端となるように構成され、前記連結部が前記搬送方向に厚みを有するスペーサ（６）で構成されることにより、前記圧電体の下端と前記第１の弾性体の下端との間に前記搬送方向の間隔（Ｄ）が設けられ、前記圧電体、前記連結部及び前記第１の弾性体よりなる駆動部が全体としてＵ字状に構成されていることを特徴とする。In view of such a situation, the vibratory transfer device of the present invention is arranged via a support (1, 1 ′, 7) and a vibration body (3, 4, 5, 6) above the support. In the vibration-type transfer device comprising the transfer body (2, 2 '), the piezoelectric body is connected to the support portion (1a') of the support body at the upper end and extends downward from the support portion. (3) and a first elastic body connected to the lower end of the piezoelectric body and extending upward behind the piezoelectric body in the transport direction and coupled to the transport body at a first position (2a ′). 4) and a second elastic body (5) that directly connects the transport body and the support body at a second position (2b ′, 1b ′) positioned forward in the transport direction from the first position. ) and a, wherein the piezoelectric coupling portion of the first elastic body (6) is configured such that the free end, the connecting portion By comprising the spacer (6) having a thickness in the conveyance direction, a gap (D) in the conveyance direction is provided between the lower end of the piezoelectric body and the lower end of the first elastic body, and the piezoelectric The drive part which consists of a body, the said connection part, and the said 1st elastic body is comprised by the U-shape as a whole, It is characterized by the above-mentioned.

この発明によれば、圧電体が支持部位を中心として撓み変形することで、自由端として構成される圧電体と第１の弾性体の連結部が搬送方向前後に回動し、これによって第１の弾性体及び第２の弾性体により搬送方向の前後位置で弾性支持された搬送体の後部が上下・前後に揺動するため、搬送体上の搬送物を効率的に移動させることが可能になる。したがって、複数の加振体を搬送方向の前後にそれぞれ配置する必要がないので、加振体間の動作調整が不要になるとともに製造コストを低減でき、しかも、動作効率を向上させることができるため、より高いレベルで搬送性能の向上と消費電力の低減を両立させることができる。また、連結部にスペーサを介在させることで両者間を容易に連結でき、圧電体と第１の弾性体の干渉を防止してそれぞれの変形動作を妨げなく実現できるとともに、両者間に搬送方向の間隔を確保できるため、搬送体の揺動を大きくすることが可能になる。 According to the present invention, the piezoelectric body is bent and deformed around the support portion, so that the connecting portion between the piezoelectric body configured as the free end and the first elastic body is rotated back and forth in the transport direction, whereby the first Since the rear part of the transport body elastically supported by the elastic body and the second elastic body at the front and rear positions in the transport direction swings up and down and back and forth, it is possible to efficiently move the transported object on the transport body Become. Therefore, since it is not necessary to arrange a plurality of vibrators before and after in the transport direction, it is not necessary to adjust the operation between the vibrators, the manufacturing cost can be reduced, and the operation efficiency can be improved. Therefore, at a higher level, it is possible to achieve both improvement in conveyance performance and reduction in power consumption. In addition, by interposing a spacer in the connecting portion, the two can be easily connected to each other, the interference between the piezoelectric body and the first elastic body can be prevented and the respective deformation operations can be realized without hindering, and the conveying direction between them can be realized. Since the interval can be secured, it is possible to increase the swing of the transport body.

本発明の一の態様においては、前記支持体（１，１′，７）は、支持板（１）と、該支持板上に固定され、上方後部に前記支持部位を備えた側面視でクランク状に構成された支持ブロック（１′）とを有する。これによれば、圧電体の基端を固定するために必要な剛性を確保しつつ加振体周辺の質量の増加を抑制する。また、支持体に後述する慣性重量を設ける場合には、当該慣性重量による慣性モーメントの向上効果を高めることができる。 In one aspect of the present invention, the support (1, 1 ', 7) is a crank in a side view that is fixed on the support plate (1) and the support plate, and has the support portion at the upper rear part. And a support block (1 ') configured in a shape. According to this, an increase in the mass around the vibrating body is suppressed while ensuring the rigidity necessary for fixing the base end of the piezoelectric body. In addition, when the inertia weight described later is provided on the support, the effect of improving the moment of inertia due to the inertia weight can be enhanced.

本発明の他の態様においては、前記支持体（１，１′，７）には、前記第１の位置より前記搬送方向の後方に慣性質量（７）が設けられる。これによれば、慣性質量を支持体の第１の位置より搬送方向に見て後方に設けることで、装置の大型化を回避しつつ、搬送体を効率的に揺動させて搬送方向の推進力を高めることができる。   In another aspect of the invention, the support (1, 1 ', 7) is provided with an inertial mass (7) behind the first position in the transport direction. According to this, by providing the inertial mass behind the first position of the support body in the transport direction, the transport body can be efficiently swung and the transport direction can be propelled while avoiding an increase in the size of the apparatus. You can increase your power.

本発明の異なる態様においては、前記支持体が防振体（８）を介して設置部（９）上に設置される。支持体が防振体を介して設置されることで、支持体の揺動を抑制できるとともに、支持体から設置部へ漏れる振動エネルギーを低減し、搬送効率をさらに向上させることができる。   In the different aspect of this invention, the said support body is installed on an installation part (9) through a vibration isolator (8). By installing the support via the vibration isolator, the swing of the support can be suppressed, vibration energy leaking from the support to the installation portion can be reduced, and the conveyance efficiency can be further improved.

以下、本発明の実施の形態を図示例と共に説明する。図１は本実施形態の振動式搬送装置（直線フィーダ）を示す概略構成図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a vibration type conveying apparatus (linear feeder) of the present embodiment.

本実施形態の振動式搬送装置においては、平坦な支持板１上に支持ブロック１′が固定され、この支持ブロック１′の上方後部（支持部位）１ａ′に圧電体３の上端（基端）が連結される。圧電体３はシム板等よりなる弾性板の表面に圧電層を積層して撓み変形可能に構成したもので、例えばバイモルフ型（圧電層が表裏両面に積層されている場合）、或いはユニモルフ型（圧電層が表裏いずれかの面に積層されている場合）の圧電アクチュエータとして構成される。支持ブロック１′は圧電体３の基端を支持板１に固定するために必要な剛性を有するものであればよい。支持ブロック１′は図示例では側面視でクランク状に構成され、これによって第１の弾性板４及び第２の弾性板５のいずれにも支持ブロック１′を接続可能に構成するとともに、上記の剛性を確保しつつ加振体周辺の質量の増加を抑制し、後述する慣性質量７による慣性モーメントの向上効果を高めている。   In the vibration type conveying apparatus of the present embodiment, a support block 1 ′ is fixed on a flat support plate 1, and the upper end (base end) of the piezoelectric body 3 is located at the upper rear part (support part) 1 a ′ of the support block 1 ′. Are concatenated. The piezoelectric body 3 is configured such that a piezoelectric layer is laminated on the surface of an elastic plate made of a shim plate or the like so that it can be bent and deformed. For example, a bimorph type (when the piezoelectric layer is laminated on both front and back surfaces) or a unimorph type ( (When the piezoelectric layer is laminated on either of the front and back surfaces). The support block 1 ′ only needs to have a rigidity necessary for fixing the base end of the piezoelectric body 3 to the support plate 1. In the illustrated example, the support block 1 ′ is configured in a crank shape in a side view, and thus the support block 1 ′ can be connected to both the first elastic plate 4 and the second elastic plate 5, and While securing rigidity, an increase in the mass around the vibrating body is suppressed, and the effect of improving the moment of inertia by the inertial mass 7 described later is enhanced.

圧電体３の下端はスペーサ６の前端部に連結され、スペーサ６の後端部には第１の弾性板（板バネ）４の下端が連結される。このスペーサ６は圧電体３の下端と第１の弾性板４の下端とを連結する連結部を構成する。また、スペーサ６は搬送方向Ｆに厚みを有することで、圧電体３の下端と第１の弾性板４の下端との間に搬送方向Ｆの間隔Ｄを設けている。   The lower end of the piezoelectric body 3 is connected to the front end portion of the spacer 6, and the lower end of the first elastic plate (leaf spring) 4 is connected to the rear end portion of the spacer 6. The spacer 6 constitutes a connecting portion that connects the lower end of the piezoelectric body 3 and the lower end of the first elastic plate 4. Further, the spacer 6 has a thickness in the transport direction F, so that an interval D in the transport direction F is provided between the lower end of the piezoelectric body 3 and the lower end of the first elastic plate 4.

第１の弾性板４の上端は上方に配置された搬送体の後方部位（トラフ２′の後端）２ａ′に連結される。本実施形態の場合、搬送体は部品Ｗを案内するトラック２ｓを備えた搬送板２と、この搬送板２が固定されてなるトラフ２′で構成される。   The upper end of the first elastic plate 4 is connected to a rear portion (rear end of the trough 2 ') 2a' of the transport body disposed above. In the case of the present embodiment, the transport body is composed of a transport plate 2 provided with a track 2s for guiding the component W, and a trough 2 'to which the transport plate 2 is fixed.

上記の構成により、圧電体３、スペーサ６及び第１の弾性板４よりなる駆動部は全体としてＵ字状に構成され、スペーサ６で構成される連結部は自由端として動作するようになっている。ここで、支持部位である上記上方後部１ａ′が固定されているとすれば、スペーサ６（連結部）の前端は支持部位側の基端Ｏを中心に図示矢印Ｔに示すように撓み変形する。また、上記後方部位２ａ′より搬送方向Ｆの前方に位置する前方部位（トラフ２′の前端）２ｂ′には第２の弾性板（板バネ）５の上端が連結され、当該第２の弾性板５の下端は上記支持ブロックの下方前部１ｂ′に連結される。これにより、搬送体２は、搬送方向Ｆの前後の位置においてそれぞれ第１の弾性板４と第２の弾性板５によって支持された状態とされる。   With the above configuration, the drive unit including the piezoelectric body 3, the spacer 6, and the first elastic plate 4 is configured in a U shape as a whole, and the coupling unit configured by the spacer 6 operates as a free end. Yes. Here, if the upper rear portion 1a ′ that is the support portion is fixed, the front end of the spacer 6 (connecting portion) is bent and deformed as shown by the arrow T in the drawing centering on the base end O on the support portion side. . An upper end of a second elastic plate (leaf spring) 5 is connected to a front portion (front end of the trough 2 ') 2b' located in front of the conveyance direction F from the rear portion 2a '. The lower end of the plate 5 is connected to the lower front portion 1b 'of the support block. As a result, the transport body 2 is supported by the first elastic plate 4 and the second elastic plate 5 at positions before and after in the transport direction F, respectively.

支持板１の後部上には慣性質量７が固定される。慣性質量７は、支持板１、支持ブロック１ａ及び慣性質量７からなる支持体の重心を搬送方向Ｆの後方に移動させるためのものであり、好ましくは、当該重心が圧電体３、スペーサ６及び第１の弾性板４よりなる駆動部よりも搬送方向Ｆに見て後方に位置するように構成される。   An inertial mass 7 is fixed on the rear part of the support plate 1. The inertial mass 7 is for moving the center of gravity of the support composed of the support plate 1, the support block 1a, and the inertial mass 7 to the rear in the transport direction F. Preferably, the center of gravity is the piezoelectric body 3, the spacer 6, and It is configured to be positioned rearward when viewed in the transport direction F with respect to the drive unit made of the first elastic plate 4.

上記搬送体の効率的な振動を確保するために支持体の質量は搬送体の質量より十分に大きく構成される。また、慣性質量７は上記基端Ｏを中心とする支持体の慣性モーメントを搬送体よりも大きくしている。   In order to ensure efficient vibration of the carrier, the mass of the support is configured to be sufficiently larger than the mass of the carrier. Further, the inertial mass 7 makes the moment of inertia of the support centered on the base end O larger than that of the carrier.

支持板１は設置板９上に防振体である複数の防振材８を介して搭載される。防振材８は、ゴム、ばね（コイルばね）等の弾性素材で構成され、支持板１の振動が設置板９側へ漏出することを抑制する。特に、本実施形態では、後述する搬送体の揺動に起因する支持体への反動を吸収する。   The support plate 1 is mounted on the installation plate 9 via a plurality of vibration isolation materials 8 that are vibration isolation bodies. The vibration isolator 8 is made of an elastic material such as rubber or a spring (coil spring), and suppresses the vibration of the support plate 1 from leaking to the installation plate 9 side. In particular, in the present embodiment, the reaction to the support due to the swinging of the transfer body described later is absorbed.

本実施形態において、上記の圧電体３の撓み変形Ｔにより搬送体は下方に揺動中心を有する態様で図示矢印Ｇで示すように揺動し、また、前方に揺動中心を有する態様で図示矢印Ｕで示すように揺動し、全体として搬送方向Ｆの前方に向けて斜め上方に振動するため、これによって搬送板２上の部品Ｗを搬送方向Ｆに搬送することができる。搬送体の揺動Ｇ及びＵは、従来の振動式搬送装置のように圧電体３、第１の弾性板４及び第２の弾性板５よりなる駆動部が搬送方向Ｆとは反対側に傾斜していなくても、ワークを効率的に搬送方向Ｆに移動させることを可能にする。もっとも、このことは、当該駆動部を図示例のように垂直姿勢とする態様に限定するものではなく、圧電体３及び両弾性板４，５を傾斜姿勢に設置しても構わない。   In this embodiment, due to the bending deformation T of the piezoelectric body 3 described above, the transport body swings as shown by an arrow G in a mode having a swing center downward, and is illustrated in a mode having a swing center in the front. As shown by the arrow U, it swings and vibrates obliquely upward toward the front in the transport direction F as a whole, so that the component W on the transport plate 2 can be transported in the transport direction F. As for the swinging G and U of the transport body, the drive unit composed of the piezoelectric body 3, the first elastic plate 4 and the second elastic plate 5 is inclined to the opposite side to the transport direction F as in the case of the conventional vibration type transport device. Even if it is not, it is possible to efficiently move the workpiece in the conveyance direction F. However, this is not limited to a mode in which the driving unit is in a vertical posture as in the illustrated example, and the piezoelectric body 3 and both elastic plates 4 and 5 may be installed in an inclined posture.

ここで、スペーサ６の厚みを増加させて圧電体３と第１の弾性板４の連結部における搬送方向Ｆの間隔Ｄが大きくなると、撓み変形Ｔに起因する図示矢印Ｓで示す第１の弾性板４の上下方向の振れも大きくなるため、揺動Ｕの振幅が増大する。しかしながら、揺動ＧとＵの関係に応じて搬送効率が変動するので、部品Ｗに適した効率的な振動態様を得るために揺動Ｇ及びＵの最適な関係を実現するには上記間隔Ｄを適宜に設定する必要がある。   Here, when the thickness of the spacer 6 is increased and the distance D in the transport direction F at the connecting portion between the piezoelectric body 3 and the first elastic plate 4 is increased, the first elasticity indicated by the illustrated arrow S caused by the bending deformation T is obtained. Since the vertical deflection of the plate 4 also increases, the amplitude of the swing U increases. However, since the conveyance efficiency varies depending on the relationship between the swings G and U, the distance D is used to realize the optimal relationship between the swings G and U in order to obtain an efficient vibration mode suitable for the component W. Must be set appropriately.

また、搬送体の揺動Ｇ及びＵの態様は、支持体（支持板１、支持ブロック１′及び慣性質量７）と搬送体（搬送板２、トラフ２′）の単なる質量比のみによって定まるのではなく、支持体と搬送体の上記基端Ｏを中心とする慣性モーメントの比にも依存する。ここで、慣性質量７を搬送方向の前後に配置することで、支持体の慣性モーメントを増大させ、これによって搬送体を効率的に揺動させることができるようになっている。特に、本実施形態では支持体において搬送体の後端部位２ａ′（或いは、上記駆動部）より搬送方向Ｆに見て後方に慣性質量７を配置することで、慣性モーメントを増加させつつ、装置の前後方向の長さを抑制することが可能になる。   In addition, the modes of the swinging G and U of the transport body are determined only by the simple mass ratio of the support body (support plate 1, support block 1 'and inertial mass 7) and the transport body (transport plate 2, trough 2'). Instead, it also depends on the ratio of the moment of inertia around the base end O of the support and the transport body. Here, by disposing the inertial mass 7 before and after in the transport direction, the moment of inertia of the support body is increased, whereby the transport body can be efficiently swung. In particular, in the present embodiment, the inertia mass 7 is arranged behind the rear end portion 2a ′ (or the drive unit) of the transport body in the transport direction F in the support body, thereby increasing the moment of inertia while increasing the moment of inertia. It is possible to suppress the length in the front-rear direction.

尚、本発明の振動式搬送装置は、上述の図示例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。例えば、上記実施形態は直線フィーダ（部品を整列させて一列に供給する搬送装置）を構成した例を示すものであるが、本発明は当該実施形態に限らず、例えば、振動式ホッパ（複数の部品を塊状でボウルフィーダや直線フィーダ等に供給する搬送装置）等にも適用できる。   Note that the vibratory conveyance device of the present invention is not limited to the above-described illustrated examples, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, although the said embodiment shows the example which comprised the linear feeder (conveying apparatus which aligns components and supplies in a row), this invention is not limited to the said embodiment, For example, vibration type hopper (several hoppers) The present invention can also be applied to a conveying device that supplies parts to a bowl feeder or a linear feeder in a lump.
