Description

本発明は振動式部品搬送装置に係り、特に、軸線周りの回転振動によって螺旋状の搬送路に沿って部品を搬送する装置の構造に関する。   The present invention relates to a vibration type component conveying apparatus, and more particularly to a structure of an apparatus that conveys a component along a helical conveying path by rotational vibration around an axis.

一般に、パーツフィーダと呼ばれる部品搬送装置としては、内周面に螺旋状の搬送路を形成したボウル状の搬送振動体を用意し、この搬送振動体の内底部に大量の部品を溜めておくとともに、搬送振動体に軸線周りの回転振動を与えることにより、上記螺旋状の搬送路に沿って部品を徐々に整列させながら搬送していく形式の装置が知られている。   In general, as a parts conveying device called a parts feeder, a bowl-shaped conveying vibration body having a spiral conveying path formed on the inner peripheral surface is prepared, and a large amount of parts are stored at the inner bottom of the conveying vibration body. An apparatus of a type that conveys components while gradually aligning the components along the spiral conveying path by applying rotational vibration around the axis to the conveying vibration body is known.

この種の部品搬送装置においては、図１０に示すように、軸線周りの回転振動を与える回転振動機１の振動盤１ａ上にボウル状の搬送振動体２を固定する必要があるが、微細な部品を大量に搬送するための小型の部品搬送装置の場合には、第１の固定構造として、一体成型品として構成された搬送振動体２の底部中央に貫通孔２ａを垂直に形成し、この貫通孔２ａにボルト３を通して回転振動機１の振動盤１ａに螺合させることで、当該ボルト３によって搬送振動体２の中心部を振動盤１ａに対し軸線方向に締め付け固定するようにしていた。   In this type of component conveying device, as shown in FIG. 10, it is necessary to fix a bowl-shaped conveying vibrator 2 on a vibration plate 1a of a rotary vibrator 1 that applies rotational vibration around an axis. In the case of a small component conveying device for conveying a large amount of components, as a first fixing structure, a through hole 2a is formed vertically in the center of the bottom of the conveying vibration body 2 configured as an integrally molded product. By screwing the through-hole 2a with the vibration plate 1a of the rotary vibrator 1 through the bolt 3, the central portion of the conveying vibration body 2 is fastened and fixed to the vibration plate 1a in the axial direction by the bolt 3.

また、比較的大きめの部品を搬送するための大型の部品搬送装置の場合には、板金により形成された円筒状の外周壁の内側に螺旋帯状の金属板を接合して搬送路を構成してなる搬送振動体を用いることが多い。このような搬送振動体を用いるときには、第２の固定方法として、搬送振動体の上記外周壁の底部を回転振動機の振動盤の外周部に外側から直接当接させるとともに、当該外周壁の底部の外側から締付板を当てて当該締付板をボルトによって振動盤に対して半径方向に締付固定して上記底部を挟持してなる固定部位を外周に沿った複数箇所に設けることにより、搬送振動体を振動盤に固定するようにしていた（例えば、以下の特許文献１参照）。   In addition, in the case of a large-sized component conveying device for conveying relatively large components, a conveying path is configured by joining a spiral belt-shaped metal plate to the inside of a cylindrical outer peripheral wall formed of sheet metal. In many cases, a conveying vibrator is used. When using such a conveying vibration body, as a second fixing method, the bottom portion of the outer peripheral wall of the conveying vibration member is brought into direct contact with the outer peripheral portion of the vibration plate of the rotary vibrator from the outside, and the bottom portion of the outer peripheral wall is used. By applying a fastening plate from the outside of the base plate and fastening the fastening plate in a radial direction with respect to the diaphragm with bolts, and providing a fixed portion sandwiching the bottom portion at a plurality of locations along the outer periphery, The conveying vibrator is fixed to the diaphragm (for example, refer to Patent Document 1 below).

また、このような大型の搬送振動体を備えた部品搬送装置における搬送振動体と振動盤の第３の固定方法としては、搬送振動体の底部に環状の脚部を設け、当該脚部を振動盤において立設された取付リブの外側に嵌合させた状態で、上記脚部を貫通し上記取付リブに螺合するボルトで半径方向に直接締め付けて固定する構造もある（例えば、以下の特許文献２参照）。   In addition, as a third fixing method of the conveying vibration body and the vibration plate in the component conveying apparatus having such a large conveying vibration body, an annular leg portion is provided at the bottom of the conveying vibration body, and the leg portion is vibrated. There is also a structure that is fixed by directly tightening in the radial direction with a bolt that penetrates the leg portion and is screwed into the mounting rib while being fitted to the outside of the mounting rib standing on the board (for example, the following patents) Reference 2).

さらに、振動盤の外周部を外側へ張り出させてなる外周張出部を設けるとともに当該外周張出部に上下方向斜めに貫通孔を形成し、振動盤上に載置される搬送振動体の底部の外周部上に配置される取付ブロックを、上記貫通孔を通して螺合するボルトにより締め付けることで、取付ブロックが搬送振動体の底部を軸線方向に押さえ付けて上記外周張出部を挟持するようにした第４の固定方法も知られている（例えば、以下の特許文献３参照）。   In addition, an outer periphery overhanging portion that projects the outer periphery of the vibration plate to the outside is provided, and a through hole is formed in the outer periphery overhanging portion obliquely in the vertical direction. The mounting block arranged on the outer peripheral portion of the bottom portion is tightened with a bolt that is screwed through the through hole, so that the mounting block presses the bottom portion of the conveying vibration body in the axial direction and sandwiches the outer peripheral protruding portion. A fourth fixing method is also known (for example, see Patent Document 3 below).

しかしながら、上記第１の固定方法においては、搬送振動体の底部中央を振動盤にボルトによって軸線方向に締付固定しているだけであるので、搬送振動体の外周部が振動盤の外周部に直接固定されていないため、搬送振動体の変形により外周部に不要振動が生じて効率的な搬送態様や部品の整列姿勢を阻害するとともに、回転方向の応力に対する固定力が中心部における摩擦力のみに依存しているため、振動周波数が高くなると、回転振動機の振動盤とこれに固定されている搬送振動体が軸線周りに回転ずれを生じることから、振動盤と搬送振動体の接触面間の擦れにより騒音が生じたり接触面にすり傷が生じて固定状態が変化したりするという問題点がある。特に、圧電体に対する駆動電圧を高めることなどにより回転振動の振幅を増加させた場合には、上記の騒音がひどくなるとともに、搬送振動体上の部品が暴れて効率的な搬送ができなくなる上に部品の整列姿勢にも悪影響を与えるという問題点があった。   However, in the first fixing method, since the center of the bottom portion of the conveying vibration body is only fastened and fixed to the vibration plate by the bolt in the axial direction, the outer peripheral portion of the conveying vibration member is connected to the outer peripheral portion of the vibration plate. Because it is not directly fixed, unnecessary vibration occurs in the outer periphery due to deformation of the transfer vibrating body, which hinders efficient transfer mode and part alignment posture, and the fixing force against stress in the rotational direction is only the frictional force at the center Therefore, if the vibration frequency increases, the vibration plate of the rotary vibrator and the conveyance vibration member fixed to the vibration plate will be rotationally displaced around the axis, so that there is a gap between the contact surface of the vibration plate and the conveyance vibration member. There is a problem that noise is generated due to rubbing, and scratches are generated on the contact surface to change the fixed state. In particular, when the amplitude of rotational vibration is increased by increasing the driving voltage for the piezoelectric body, the above-mentioned noise becomes severe, and the parts on the transport vibration body become violent and efficient transport cannot be performed. There was a problem that the alignment posture of the parts was also adversely affected.

上記の問題点は軸線方向の締付固定力により振動盤と搬送振動体を回転振動の軸線付近のみで固定していることに起因するものであるために、締付固定力を大きくしても根本的な解決にはならない。また、変形を低減するために搬送振動体の剛性を高めると、必然的に搬送振動体の軽量化が難しくなるという別の問題点も生ずる。この搬送振動体の軽量化は、近年の搬送速度の向上の要請に応えるために回転振動数を高めようとする場合には極めて重要な課題である。特に、小型の部品搬送装置の場合には近年において圧電振動体を用いた回転振動機が多くなってきていることから、搬送振動体の重量が大きい場合には、圧電振動体の剛性を高めるためにコストが上昇したり、圧電振動体の耐久性が低下したりするという問題を生じやすい。   The above problem is caused by the fact that the vibration plate and the conveying vibration body are fixed only in the vicinity of the axis of rotational vibration by the axial fastening force, so even if the fastening force is increased. It is not a fundamental solution. In addition, if the rigidity of the conveying vibration body is increased in order to reduce deformation, another problem that it is inevitably difficult to reduce the weight of the conveying vibration body occurs. This weight reduction of the conveying vibrator is an extremely important issue when trying to increase the rotational frequency in order to meet the recent demand for improvement in the conveying speed. In particular, in the case of a small component conveying device, since the number of rotary vibrators using a piezoelectric vibrator has increased in recent years, in order to increase the rigidity of the piezoelectric vibrator when the weight of the conveying vibrator is large. In addition, the cost tends to increase and the durability of the piezoelectric vibrating body tends to decrease.

一方、第２の固定方法や第３の固定方法においては、搬送振動体の外周底部を振動盤に固定していることから上記のような各種の問題点は生じないが、搬送振動体を振動盤に対し半径方向に直接に締付固定していることにより軸線方向の固定力や固定精度が不十分で、回転振動を搬送振動体に充分に精度良く伝達することができないことから、微細な電子部品を効率的かつ高精度に搬送することができないという問題点がある。また、このような固定方法を採用する搬送振動体は金属板を溶接等により接合して構成したものが多いため、部品の搬送速度を高めるために振動周波数を高くすると各部の金属板がそれぞれ厚み方向に振動するなどの不要振動が発生しやすくなるので、搬送振動体自体の構造によっても搬送部品の微細化や搬送速度の高速化に支障が出るという問題点がある。また、搬送振動体と振動盤をボルトによる直接固定が可能な構造とする必要があるので、微細な電子部品を搬送するための高精度な形状を備えた一体成形品（削り出し一体品を含む。）で形成されてなる搬送振動体では加工作業や剛性の確保が難しいという問題点がある。   On the other hand, in the second fixing method and the third fixing method, since the outer peripheral bottom portion of the conveying vibration body is fixed to the vibration plate, the above various problems do not occur, but the conveying vibration body is vibrated. Since the clamping force and fixing accuracy in the axial direction are insufficient due to the direct clamping and fixing to the panel in the radial direction, the rotational vibration cannot be transmitted to the conveying vibrator with sufficient accuracy. There is a problem that electronic components cannot be efficiently and accurately conveyed. In addition, since many conveyance vibrators adopting such a fixing method are formed by joining metal plates by welding or the like, if the vibration frequency is increased to increase the conveyance speed of the parts, the thickness of each part of the metal plate is increased. Since unnecessary vibration such as vibration in the direction is likely to occur, there is a problem that the structure of the transport vibration body itself hinders the miniaturization of the transport parts and the increase of the transport speed. Also, since it is necessary to have a structure that can directly fix the conveying vibration body and the vibration plate with bolts, an integrally formed product (including a cut-out integrated product) with a highly accurate shape for conveying fine electronic components is required. )) Has a problem that it is difficult to secure machining work and rigidity.

また、第４の固定方法では、搬送振動体を振動盤に対し軸線方向に締付固定していることから、特に軸線と直交する面に沿った水平方向の位置ずれを回避することが困難であるため、上記と同様に効率的かつ高精度の回転振動の伝達が難しいという問題点がある。また、振動盤の外周に大きく張り出した外周張出部を設ける必要があるので、回転振動に対する負荷重量が大きくなるとともにコンパクト化が困難であり、しかも、搬送振動体の底部に外周に張り出す面を備えた取付部を形成する必要があるので、溶接等による板金加工により形成した搬送振動体ではともかく、微細な電子部品を搬送するための高精度な形状を備えた一体成形品（削り出し一体品を含む。）で形成されてなる搬送振動体では加工作業や剛性の確保が難しいという問題点がある。   Further, in the fourth fixing method, since the conveying vibration body is fastened and fixed to the diaphragm in the axial direction, it is particularly difficult to avoid a horizontal displacement along a plane orthogonal to the axial line. For this reason, there is a problem in that it is difficult to transmit rotational vibrations efficiently and with high accuracy as described above. In addition, since it is necessary to provide an outer peripheral protruding portion that protrudes greatly on the outer periphery of the vibration plate, the load weight against rotational vibration increases and it is difficult to make it compact, and the surface protrudes to the outer periphery at the bottom of the conveying vibration body. Because it is necessary to form a mounting part with a high-precision shape for transporting fine electronic components (cut-out integrated) There is a problem that it is difficult to secure processing work and rigidity with the conveyance vibrator formed by the above.

さらに、上記第２乃至第４の固定方向においてはいずれもボルトによる螺合構造により搬送振動体を振動盤に対し半径方向若しくは軸線方向に直接固定したり、締付板や取付ブロックで挟持しているので、複数箇所で締付固定した場合、全ての箇所でボルトを外したり締め付けたりしないと搬送振動体を振動盤より取り外したり取り付けたりすることができないため、着脱作業が煩雑であるという問題点もある。   Furthermore, in any of the second to fourth fixing directions, the conveying vibration body is directly fixed to the vibration plate in the radial direction or the axial direction by a screwed structure using bolts, or is clamped by a clamping plate or a mounting block. Therefore, when tightening and fixing at multiple locations, the transport vibrator cannot be removed from or attached to the diaphragm unless the bolts are removed or tightened at all locations, making the installation and removal work complicated. There is also.

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、回転振動機で発生する回転振動を搬送振動体に対して効率的かつ高精度に伝達することができるように構成することにより、微細な搬送部品を高精度に整列搬送させることができ、高速搬送も容易に行える振動式部品搬送装置を実現することにある。   Therefore, the present invention solves the above-mentioned problems, and the problem is to configure so that the rotational vibration generated in the rotary vibrator can be efficiently and accurately transmitted to the conveying vibrator. Accordingly, an object of the present invention is to realize a vibration type component conveying apparatus capable of aligning and conveying fine conveyance parts with high accuracy and easily performing high-speed conveyance.

斯かる実情に鑑み、本発明の振動式部品搬送装置は、振動盤を軸線周りに振動させる回転振動機と、前記振動盤上に載置されるとともに前記軸線周りに設けられた螺旋状の搬送路を備えた搬送振動体と、を具備する振動式部品搬送装置において、前記搬送振動体は、内底部と、該内底部の半径方向外側に環状に構成され前記搬送路が設けられた外周部とを有し、前記外周部の底部に前記振動盤の表面上に密接して載置される外側載置面が形成され、前記外側載置面の外側で前記搬送振動体の外周部が前記振動盤の外周部と前記軸線周りの複数箇所でクランプ構造により固定され、前記クランプ構造は、前記振動盤と前記搬送振動体のうちの一方の外周部に取り付けられたクランプ部材と、前記振動盤と前記搬送振動体のうちの他方の外周部に形成され前記クランプ部材と軸線方向に係合する傾斜係合面とを有し、前記傾斜係合面は前記軸線方向に対して傾斜して前記一方の外周部とは反対側に向くとともに前記軸線と直交する面内においては複数の前記クランプ構造の少なくとも二つの間で相互に異なる向きに設定され、前記クランプ部材に設けられたクランプ面が前記傾斜係合面に密接して押し付けられることで前記搬送振動体が前記振動盤上に固定され、前記クランプ構造は前記軸線周りの三箇所以上に設けられるとともに、該三箇所以上の前記クランプ構造において前記クランプ部材は前記他方の外周部に対する締付固定力が調整可能となる態様でそれぞれ個別に前記一方の外周部に対して取付固定され、少なくとも一つの前記クランプ構造を除く、前記他方の外周部に対して取り外し可能に構成された一部の前記クランプ構造の操作のみで、前記振動盤に対し前記搬送振動体が着脱可能となるように構成されていることを特徴とする。 In view of such circumstances, the vibratory component conveying device of the present invention includes a rotary vibrator that vibrates a vibration plate around an axis, and a helical conveyance that is placed on the vibration plate and provided around the axis. A vibration vibrator having a path, wherein the conveyance vibrator is formed in an annular shape on the radially outer side of the inner bottom portion and provided with the conveyance path. has the door, an outer mounting surface to be mounted closely on the surface of the bottom portion to the vibration plate of the outer peripheral portion is formed, the outer peripheral portion of the conveying vibrator outside of the outer mounting surface The outer periphery of the vibration plate is fixed by a clamp structure at a plurality of locations around the axis, and the clamp structure includes a clamp member attached to one outer periphery of the vibration plate and the conveying vibration body, and the vibration On the other outer peripheral part of the board and the conveying vibrator An inclined engaging surface that engages with the clamp member in the axial direction, and the inclined engaging surface is inclined with respect to the axial direction and faces away from the one outer peripheral portion, and the axial line In a plane orthogonal to the at least two of the plurality of clamp structures, the clamp surfaces provided on the clamp member are pressed in close contact with the inclined engagement surface. A conveying vibration body is fixed on the vibration plate, and the clamp structure is provided at three or more locations around the axis. In the clamp structure at the three or more locations, the clamp member is fastened and fixed to the other outer peripheral portion. In a manner in which the force can be adjusted, each is individually attached and fixed to the one outer peripheral portion, and at least one of the clamp structures is excluded from the other outer peripheral portion. In operation removably part configured the clamp structure only, wherein the conveying vibrator to the vibration plate is configured to be detachable.

この発明によれば、クランプ部材のクランプ面が傾斜係合面に係合することで、振動盤の外周部と、その表面上に密接して載置された搬送振動体の外周部とがクランプ構造により固定されることにより、搬送振動体の外周部に直接に回転振動が与えられるので、搬送振動体の搬送路までの間の変形や歪が低減され、結果として振動盤で発生する回転振動を効率的かつ高精度に部品に伝えることが可能になる。また、複数のクランプ構造間で異なる向きに設定され軸線方向に対して傾斜した傾斜係合面とクランプ面の密接により、搬送振動体を軸線方向と水平方向にそれぞれ固定できるとともに、軸線方向と水平方向のいずれか一方の固定作用を摩擦力に依存した従来の固定方法に比べて、両方向に与えられる固定力の偏りが低減されるので、振動盤から搬送振動体へ向けて回転振動を効率的かつ高精度に伝達することができる。したがって、微細な搬送部品を高精度に整列搬送させることができるとともに、部品搬送の速度の向上を図ることができる。また、各クランプ構造においては傾斜係合面にクランプ面を密接させるように傾斜した向きに押し当てるだけの構造とした上で、このような複数のクランプ構造を傾斜係合面が水平面内で相互に異なる向きに設定して設けることで搬送振動体を振動盤に対して固定できるため、従来構造のように複数の固定部分において搬送振動体と振動盤を直接固定したり挟持したりしている構成において全ての固定部分を着脱させる必要があることと比べると、少なくとも一つのクランプ構造を除く一部のクランプ構造のみを操作するだけで着脱作業が可能になるという利点もある。   According to the present invention, the clamp surface of the clamp member is engaged with the inclined engagement surface, so that the outer peripheral portion of the vibration plate and the outer peripheral portion of the conveying vibration body placed in close contact with the surface are clamped. By being fixed by the structure, rotational vibration is directly applied to the outer periphery of the conveying vibration body, so that deformation and distortion of the conveying vibration body up to the conveyance path are reduced, and as a result, rotational vibration generated in the vibration plate Can be transmitted to the parts efficiently and with high accuracy. In addition, the conveying vibration body can be fixed in the axial direction and the horizontal direction by the close contact between the inclined engaging surface and the clamping surface which are set in different directions between the plurality of clamp structures and inclined with respect to the axial direction. Compared to conventional fixing methods that rely on frictional force to fix one of the directions, the bias of the fixing force applied in both directions is reduced. In addition, it can be transmitted with high accuracy. Therefore, it is possible to align and convey the fine conveyance parts with high accuracy and to improve the speed of conveyance of the parts. Further, in each clamp structure, a structure in which the clamp surface is pressed in an inclined direction so that the clamp surface is brought into intimate contact with the inclined engagement surface, and the plurality of such clamp structures are connected to each other in a horizontal plane. Since the conveying vibration body can be fixed to the vibration plate by setting it in different directions, the conveyance vibration body and the vibration plate are directly fixed or sandwiched at a plurality of fixed portions as in the conventional structure. Compared to the necessity of detaching all the fixed parts in the configuration, there is also an advantage that the detachment work can be performed only by operating only a part of the clamp structures except at least one clamp structure.

本発明の一の態様においては、前記傾斜係合面は前記軸線と直交する面内で半径方向に向くように構成され、前記クランプ部材は前記一方の外周部に対して半径方向に移動可能に構成される。これによれば、複数のクランプ構造において共に半径方向に向いた傾斜係合面を形成するとともにクランプ部材を半径方向に移動可能に構成することにより、クランプ部材を半径方向に移動させることでクランプ面と傾斜係合面の間の密接力を制御したり、振動盤に対して搬送振動体を容易に着脱することが可能になる。特に、傾斜係合面を上記面内で半径方向外側に向くように構成することで、クランプ面が半径方向外側から内側へ傾斜案内面に押し付けられた状態で搬送振動体が振動盤に固定されるので、クランプ構造の簡易化を図ることができるとともに、さらに着脱作業を容易化できる。例えば、後述する実施形態で示すように、傾斜係合面を軸線と直交する面内で半径方向外側に向くように構成し、前記一方の外周部に形成されたネジ穴にボルトを螺合させて前記クランプ部材を取り付け、前記一方の外周部に対し半径方向内側に締め付けることでクランプ面を傾斜係合面に押し付けて、搬送振動体を振動盤に固定することができるが、複数のクランプ構造のうちの一部のクランプ構造においてクランプ部材を半径方向に移動させるだけで、全ての傾斜係合面とクランプ面の密接状態を形成したり解除したりして着脱作業を行うことが可能になる。   In one aspect of the present invention, the inclined engagement surface is configured to face in a radial direction within a plane orthogonal to the axis, and the clamp member is movable in the radial direction with respect to the one outer peripheral portion. Composed. According to this, the clamp surface is formed by moving the clamp member in the radial direction by forming the inclined engagement surface facing the radial direction in the plurality of clamp structures and making the clamp member movable in the radial direction. It is possible to control the close contact force between the inclined engagement surfaces and to easily attach and detach the conveying vibrator to and from the diaphragm. In particular, the inclined engaging surface is configured to face radially outward in the above-described plane, so that the conveying vibration body is fixed to the vibration plate in a state where the clamp surface is pressed against the inclined guide surface from the radially outer side to the inner side. Therefore, the clamp structure can be simplified and the attachment / detachment operation can be further facilitated. For example, as shown in an embodiment described later, the inclined engagement surface is configured to face radially outward in a plane orthogonal to the axis, and a bolt is screwed into a screw hole formed in the one outer peripheral portion. The clamp member can be attached and the clamp surface can be pressed against the inclined engagement surface by tightening the one outer peripheral portion radially inward to fix the conveying vibration body to the vibration plate. In a part of the clamp structure, it is possible to perform attachment / detachment work by forming or releasing the close contact state between all the inclined engagement surfaces and the clamp surface only by moving the clamp member in the radial direction. .

本発明の他の態様においては、前記クランプ構造は前記軸線周りの三箇所に設けられ、該三箇所の前記クランプ構造のうち少なくとも一箇所の前記クランプ構造における一つの前記クランプ部材は前記一方の外周部に対して半径方向に移動可能に取り付けられ、前記一つの前記クランプ部材を前記半径方向に移動させることで他の二箇所の前記クランプ部材を移動させずに前記振動盤に対し前記搬送振動体を着脱できるように構成される。この場合、上記他の二箇所のクランプ構造においては、前記クランプ部材が半径方向に移動可能に構成されていてもよく、そうでなくてもよい。 In another aspect of the present invention, the clamp structure is provided at three locations around the axis, and one clamp member in at least one of the clamp structures at the three locations is the one outer periphery. movably mounted radially with respect to parts, the conveying vibrator to the vibration plate to said one of said clamping member without moving the clamping member other two positions by moving in the radial direction Is configured to be removable. In this case, in the other two clamp structures, the clamp member may or may not be configured to be movable in the radial direction.

本発明のさらに他の態様においては、前記クランプ部材は、前記一方の外周部に対して係合することで前記他方の外周部の側への移動を規制する係合爪を有する。これによれば、前記クランプ部材の前記他方の外周部の側への移動が規制されるので、クランプ面が傾斜係合面に係合することで振動盤に対して搬送振動体が固定された状態で、クランプ部材の軸線方向の位置ずれを確実に防止することができるため、搬送振動体の固定状態を安定させることができる。この係合爪は、例えば、一方の外周部における他方の外周部とは反対側の角部に係合するように構成できる。   In still another aspect of the present invention, the clamp member has an engaging claw for restricting movement toward the other outer peripheral portion by engaging with the one outer peripheral portion. According to this, since the movement of the clamp member toward the other outer peripheral portion side is restricted, the conveying vibration body is fixed to the diaphragm by engaging the clamp surface with the inclined engagement surface. Since the displacement of the clamp member in the axial direction can be reliably prevented in this state, the fixed state of the conveying vibration body can be stabilized. For example, the engaging claw can be configured to engage with a corner portion on one side of the outer peripheral portion opposite to the other outer peripheral portion.

本発明の別の態様においては、前記傾斜係合面は前記軸線と直交する面内で半径方向外側に向くように構成され、前記クランプ部材は、前記一方の外周部に対し半径方向内側に押し付けられる。これによれば、クランプ部材の一方の外周部に対する取付構造を簡易に構成できるとともに、クランプ部材の取付け作業及び取外し作業を容易化することができる。   In another aspect of the present invention, the inclined engagement surface is configured to face radially outward in a plane orthogonal to the axis, and the clamp member is pressed radially inward against the one outer peripheral portion. It is done. According to this, while being able to comprise simply the attachment structure with respect to one outer peripheral part of a clamp member, the attachment operation | work of a clamp member and the removal operation | work can be facilitated.

この場合に、前記クランプ部材を締め付けるためのボルトが設けられ、前記クランプ部材には前記ボルトが挿通する固定孔が設けられ、前記一方の外周部には前記ボルトが螺合するネジ穴が設けられることが好ましい。これによれば、簡易で安価な構造にも拘わらずクランプ部材を確実に締付できる。この場合にはさらに、前記ボルトは、雄ネジ部と、該雄ネジ部とは軸線方向の異なる位置に形成された円筒状の位置決め部とを有し、前記ネジ穴は、前記雄ネジ部に螺合する雌ネジ部と、前記位置決め部をガイドするガイド部とを有することが望ましい。これによれば、位置決め部とガイド部の嵌合により、螺合構造とは別に一方の外周部に対するボルトの位置を精密に設定することができるので、一方の外周部に対して精密に位置決めされたボルトによりクランプ部材を精密に位置決めすることができるから、クランプ面が傾斜係合面に係合することで振動盤に対して搬送振動体が固定された状態で、クランプ部材の位置ずれを確実に防止することができるため、搬送振動体の固定状態を安定させることができる。   In this case, a bolt for tightening the clamp member is provided, a fixing hole through which the bolt is inserted is provided in the clamp member, and a screw hole into which the bolt is screwed is provided in the one outer peripheral portion. It is preferable. According to this, the clamp member can be securely tightened despite the simple and inexpensive structure. In this case, the bolt further includes a male screw portion and a cylindrical positioning portion formed at a position different from the male screw portion in the axial direction, and the screw hole is formed in the male screw portion. It is desirable to have a female screw part to be screwed and a guide part to guide the positioning part. According to this, since the position of the bolt with respect to one outer peripheral portion can be set accurately separately from the screwed structure by fitting the positioning portion and the guide portion, the positioning is precisely performed with respect to one outer peripheral portion. Since the clamp member can be precisely positioned with the bolt, the clamp surface engages with the inclined engagement surface, so that the displacement of the clamp member is ensured in a state where the conveying vibration body is fixed to the vibration plate. Therefore, the fixed state of the conveyance vibrator can be stabilized.

本発明によれば、搬送振動体の外周部を振動盤の外周部に対して軸線方向と水平方向の双方に、いずれか一方への偏りを低減した態様でより確実に固定することができるため、回転振動を効率的かつ高精度に伝達することができることから、微細な搬送部品を高精度に整列搬送させることができるとともに、搬送速度の向上を図ることができるという優れた効果を奏し得る。   According to the present invention, it is possible to more reliably fix the outer peripheral portion of the conveying vibration body in both the axial direction and the horizontal direction with respect to the outer peripheral portion of the vibration plate in a manner in which the bias toward either one is reduced. Since the rotational vibration can be transmitted efficiently and with high accuracy, it is possible to achieve an excellent effect that it is possible to align and convey fine conveyance parts with high accuracy and to improve the conveyance speed.

次に、添付図面を参照して本発明の実施形態について詳細に説明する。最初に、図１乃至図４を参照して本発明に係る第１実施形態の部品搬送装置について説明する。   Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, a component conveying apparatus according to a first embodiment of the present invention will be described with reference to FIGS.

第１実施形態の部品搬送装置１０は、回転振動機１１と、この回転振動機１１上に固定された搬送振動体１２とを備えている。回転振動機１１は、設置板１３と、この設置板１３上に防振用のゴム（例えば防振リングなど）やばね（例えばコイルばねなど）からなる防振材１４を介して支持された基台１５と、この基台１５の上方に配置された振動盤（トッププレート、上板）１６とを有している。基台１５と振動盤１６との間には、基台１５の内部に配置された内部構造（図１では図示を省略してある。）１７が介在し、この内部構造１７を介して基台１５上に振動盤１６が水平に支持されている。   The component conveying apparatus 10 according to the first embodiment includes a rotary vibrator 11 and a carrier vibrator 12 fixed on the rotary vibrator 11. The rotary vibrator 11 includes a base plate 13 and a base supported on the base plate 13 via a vibration-proof material 14 made of a vibration-proof rubber (for example, a vibration-proof ring) or a spring (for example, a coil spring). A base 15 and a vibration plate (top plate, upper plate) 16 disposed above the base 15 are provided. An internal structure (not shown in FIG. 1) 17 disposed inside the base 15 is interposed between the base 15 and the diaphragm 16, and the base is interposed via the internal structure 17. A vibration plate 16 is horizontally supported on 15.

内部構造１７は、図７及び図８に示すように、部品搬送装置１０の軸線１０ｘを中心として半径方向に延在する軸線２２ｙに沿って設置され、板状の圧電駆動体２２と板ばね２３との直列接続構造を備える複数の加振機構２０を有している。図示例の場合、加振機構２０は軸線１０ｘの回りに等角度間隔で３組設置されている。この加振機構２０は、基台１５と振動盤１６の間に接続されることで、基台１５に対して振動盤１６に上記軸線１０ｘ周りの回転振動を与えるものである。基台１５の内面１５ａ（後述する傾斜角θで斜め上方を向いた面）には半径方向の軸線２２ｙと並行して延びる固定部材２１の固定部２１ｓの底面が密接した状態で固定され、この固定部材２１の上記固定部２１ｓの端部から軸線１０ｘ周りの回転方向に突出した内端部２１ａに圧電駆動体２２の内端部が接続固定されている。   As shown in FIGS. 7 and 8, the internal structure 17 is installed along an axis 22 y that extends in the radial direction about the axis 10 x of the component conveying device 10, and has a plate-like piezoelectric driver 22 and a plate spring 23. And a plurality of vibration mechanisms 20 having a series connection structure. In the case of the illustrated example, three sets of the excitation mechanisms 20 are installed at equiangular intervals around the axis 10x. The vibration mechanism 20 is connected between the base 15 and the vibration plate 16 so as to apply a rotational vibration around the axis 10 x to the vibration plate 16 with respect to the base 15. The bottom surface of the fixing portion 21s of the fixing member 21 extending in parallel with the radial axis 22y is fixed to an inner surface 15a of the base 15 (a surface facing obliquely upward at an inclination angle θ described later). An inner end portion of the piezoelectric driving body 22 is connected and fixed to an inner end portion 21a that protrudes in the rotation direction around the axis 10x from the end portion of the fixing portion 21s of the fixing member 21.

圧電駆動体２２は特に限定されるものではないが、弾性板の片面若しくは両面に圧電体層が積層された構造（ユニモルフ若しくはバイモルフ構造）を有している。圧電駆動体２２は全体として軸線２２ｙ上を半径方向に延びるとともに、垂直面（軸線１０ｘと軸線２２ｙを共に含む面）に対して傾斜角θ（図９参照）で回転方向の一方側（図７では反時計回り）の斜め上方を向くように設置されている。この傾斜角θは、搬送振動体１２内の搬送路上の部品の搬送態様に応じて適宜に設定されるが、通常５〜１５度程度である。板ばね２３も基本的には圧電駆動体２２と同様に半径方向に延びるとともに上記垂直面に対して同じ傾斜角θで斜め上方を向くように圧電駆動体２２の外端部に接続されている。   The piezoelectric driver 22 is not particularly limited, but has a structure (unimorph or bimorph structure) in which a piezoelectric layer is laminated on one side or both sides of an elastic plate. The piezoelectric driving body 22 as a whole extends in the radial direction on the axis 22y, and at one side in the rotational direction (see FIG. 9) at an inclination angle θ (see FIG. 9) with respect to a vertical plane (a plane including both the axis 10x and the axis 22y). It is installed so that it faces diagonally upward (counterclockwise). The inclination angle θ is appropriately set according to the conveyance mode of the parts on the conveyance path in the conveyance vibration body 12, but is usually about 5 to 15 degrees. The leaf spring 23 is basically connected to the outer end portion of the piezoelectric driving body 22 so as to extend in the radial direction similarly to the piezoelectric driving body 22 and to face obliquely upward at the same inclination angle θ with respect to the vertical plane. .

ただし、図示例では、圧電駆動体２２の半径方向に延在する軸線２２ｙ上に板ばね２３の外端部が配置されるように、板ばね２３を半径方向の内側から外側に向けて途中で回転方向の他方側（図７では時計回り）に湾曲させている。これによって、軸線１０ｘを通過する中心点と板ばね２３の外端部を結ぶ半径方向に圧電駆動体２２の軸線２２ｙが配置されるので、図示しない電圧印加経路によって生ずる圧電駆動体２２の撓み変形により、板ばね２３の外端部が振動盤１２に回転振動を与えるときの動作軌跡を軸線１０ｘを中心とした円弧に近い態様とすることができることから、振動盤１６を効率的かつ高精度に回転振動させることが可能になる。また、板ばね２３は幅方向の両端縁が凹曲線状に形成され、中間部が括れた形状を備えている。これは、振動盤１６や搬送振動体１２の重量により板ばね２３に加わる負荷が幅方向に偏ることにより生ずる捩じれ方向の応力を中間部に集中させることで、板ばね２３の長さ方向両端部の接続部分に亀裂が生ずることを防止するためである。   However, in the illustrated example, the leaf spring 23 is moved in the middle from the inner side to the outer side in the radial direction so that the outer end portion of the leaf spring 23 is disposed on the axial line 22 y extending in the radial direction of the piezoelectric driving body 22. It is curved to the other side in the rotation direction (clockwise in FIG. 7). As a result, the axis 22y of the piezoelectric driving body 22 is arranged in the radial direction connecting the center point passing through the axis 10x and the outer end of the leaf spring 23, so that the bending deformation of the piezoelectric driving body 22 caused by a voltage application path (not shown). Thus, the movement locus when the outer end portion of the leaf spring 23 gives rotational vibration to the diaphragm 12 can be made to be close to an arc centered on the axis 10x, so that the diaphragm 16 can be efficiently and highly accurate. It can be rotated and vibrated. Moreover, the leaf | plate spring 23 is provided with the shape where the both ends edge of the width direction was formed in the shape of a concave curve, and the intermediate part was constricted. This is because the stress in the torsional direction caused by the load applied to the leaf spring 23 being biased in the width direction due to the weight of the vibration plate 16 and the conveying vibration body 12 is concentrated in the intermediate portion, so that both end portions in the length direction of the leaf spring 23 are concentrated. This is to prevent the occurrence of cracks in the connecting portion.

上記加振機構２０の外端部（すなわち、板ばね２３の外端部）は、振動盤１２の外周部において下方に突出する態様で設けられた振動盤１６の接続部１６ａに接続固定されている。この接続部１６ａは図示例では等角度間隔で上記加振機構２０に対応する三箇所に設けられている。なお、接続部１６ａに対応して基台１５の外周部には凹部１５ｂが形成され、接続部１６ａが凹部１５ｂ内に張り出すように構成されることで、基台１５と振動盤１６とが内部構造１７（加振機構２０）を介在させている部分以外では接触しないように構成される。   The outer end portion of the vibration excitation mechanism 20 (that is, the outer end portion of the leaf spring 23) is connected and fixed to a connection portion 16a of the vibration plate 16 provided in a manner protruding downward on the outer peripheral portion of the vibration plate 12. Yes. In the illustrated example, the connecting portions 16a are provided at three locations corresponding to the vibration exciting mechanism 20 at equal angular intervals. A recess 15b is formed in the outer peripheral portion of the base 15 corresponding to the connection portion 16a, and the connection portion 16a is configured to project into the recess 15b, so that the base 15 and the diaphragm 16 are connected. It is comprised so that it may not contact except the part in which the internal structure 17 (vibration mechanism 20) is interposed.

振動盤１６は平面視円形状で、その表面（上面）１６ｓは平坦に構成される。この表面１６ｓ上には上記搬送振動体１２が載置される。搬送振動体１２は全体としてボウル状に構成されたアルミニウム又はその合金、ステンレス鋼などで形成された一体成形品（削り出しにより形成された一体品を含む。）である。搬送振動体１２は、内面１２ｓが円錐状に構成された内底部１２ａと、この内底部１２ａの半径方向外側に環状に構成された外周部１２ｂとを有し、この外周部１２ｂの内面１２ｔは逆円錐状に傾斜した傾斜面となっている。この内面１２ｔ上には、上記内底部１２ａの内面１２ｓの外周部分（最も低い部分）から螺旋状に外側へ向けて徐々に立ち上がるように形成された搬送路１２ｗ（図２参照）が形成される。この搬送路１２ｗの断面形状などの詳細構造は図示を省略するが、内面１２ｔにおいて例えば断面Ｌ字状の溝を形成したものである。振動搬送体１２の中心には中心孔１２ｇが形成され、この中心孔１２ｇを中心として回転方向に重量バランスが得られるように調整されている。内面１２ｓの上記外周部分（最下部）は部品溜まりとして用いられ、ここに溜められた部品は搬送振動体１２に回転振動が与えられることで上記搬送路１２ｗ上を徐々に上方へ向けて搬送されていくようになっている。なお、本実施形態では内面１２ｔ上に螺旋状の搬送路１２ｗが形成されているが、外周底部に部品溜まりを設けることで外周面上に螺旋状の搬送路を形成することも可能である。   The vibration plate 16 has a circular shape in plan view, and its surface (upper surface) 16s is configured to be flat. The conveyance vibrator 12 is placed on the surface 16s. The conveying vibration body 12 is an integrally formed product (including an integrated product formed by machining) formed of aluminum or an alloy thereof, stainless steel, or the like configured in a bowl shape as a whole. The conveying vibration body 12 has an inner bottom portion 12a having an inner surface 12s formed in a conical shape, and an outer peripheral portion 12b formed in an annular shape on the outer side in the radial direction of the inner bottom portion 12a. The inclined surface is inclined in an inverted conical shape. On the inner surface 12t, a conveyance path 12w (see FIG. 2) formed so as to gradually rise outward from the outer peripheral portion (lowest portion) of the inner surface 12s of the inner bottom portion 12a spirally is formed. . Although a detailed structure such as a cross-sectional shape of the transport path 12w is not shown, a groove having an L-shaped cross section, for example, is formed on the inner surface 12t. A center hole 12g is formed at the center of the vibration carrier 12, and the center is adjusted so that a weight balance can be obtained in the rotation direction around the center hole 12g. The outer peripheral portion (lowermost part) of the inner surface 12s is used as a component reservoir, and the components accumulated here are conveyed upwardly on the conveyance path 12w by applying rotational vibration to the conveying vibration body 12. It has come to go. In this embodiment, the spiral conveyance path 12w is formed on the inner surface 12t. However, it is also possible to form a spiral conveyance path on the outer peripheral surface by providing a component pool at the bottom of the outer periphery.

内底部１２ａは搬送振動体１２の重量を低減するために内面１２ｓとは反対側（底面側）が凹状に形成されることで薄く構成されている。搬送振動体１２の重量軽減は、搬送振動体１２の回転振動の周波数を高めて搬送速度を向上させる上で重要である。これは、回転振動機１１による搬送振動体１２の駆動を共振点近くで行うことで効率的に振動させることができるが、このときの共振周波数を高める上でも搬送振動体１２の軽量化が要求されるからである。一方、外周部１２ｂの肉厚を確保して剛性を高めることにより、搬送路１２ｗ上の部品を整然と効率的に搬送することを可能にしている。外周部１２ｂの剛性は微細な部品を搬送する場合には部品の暴れを防止する上で極めて重要である。回転振動機１１から伝達された回転振動に従って搬送路１２ｗも精密に回転振動すれば部品は暴れることなく姿勢を保ちつつスムーズかつ効率的に搬送されるが、外周部１２ｂの剛性が低く搬送路１２ｗが上記回転振動とは異なる態様で振動したり搬送路１２ｗに到達する前に上記回転振動が吸収されたりすれば、部品が暴れたり、効率的な部品搬送ができなくなったりする。 In order to reduce the weight of the conveyance vibrating body 12, the inner bottom portion 12a is formed thin by forming a concave side (bottom surface side) opposite to the inner surface 12s . Reducing the weight of the transport vibrator 12 is important in increasing the rotational speed of the transport vibrator 12 and improving the transport speed. This can be efficiently vibrated by driving the conveyance vibrator 12 near the resonance point by the rotary vibrator 11, but the weight of the conveyance vibrator 12 is also required to increase the resonance frequency at this time. Because it is done. On the other hand, by securing the thickness of the outer peripheral portion 12b and increasing the rigidity, it is possible to transport the parts on the transport path 12w in an orderly and efficient manner. The rigidity of the outer peripheral portion 12b is extremely important in preventing the parts from being violated when a fine part is conveyed. If the conveyance path 12w also rotates and vibrates precisely in accordance with the rotational vibration transmitted from the rotary vibrator 11, the parts are conveyed smoothly and efficiently while maintaining their postures, but the rigidity of the outer peripheral portion 12b is low and the conveyance path 12w. However, if the rotational vibration is absorbed before reaching the transport path 12w, the parts may be violated or the parts cannot be efficiently transported.

搬送振動体１２の外周部１２ｂは、上記内面１２ｔの断面形状により、全体として底部側が半径方向に厚く、上部側が半径方向に薄くなる断面を有している。また、外周部１２ｂの底部１２ｃには、下方に突出した位置に設けられ、上記振動盤１６の外周部の表面１６ｓ上に密接して載置される平坦な底面１２ｄ（上記の外側載置面に相当する。）が形成されている。この底面１２ｄは軸線１０ｘを中心とする円環帯状に構成され、振動盤１６の外周部の表面１６ｓに密接するように構成される。本実施形態では、底部１２ｃに設けられた底面１２ｄは外周部１２ｂにのみ形成され、底面１２ｄよりも内側にある領域は、内底部１２ａの底面形状が凹状に構成されることにより、振動盤１６に接触しないようになっている。このため、振動盤１６の回転振動は外周に設けられた底面１２ｄからのみ搬送振動体１２の外周部１２ｂへと伝達されるから、効率的に振動を外周部１２ｂに形成された搬送路１２ｗへ伝達することができる。なお、図示例では、搬送振動体１２の底部１２ｃの外縁は振動盤１６の外周部よりも外側に張り出しているので、平坦な底面１２ｄの外側の一部が振動盤１６の表面１６ｓと接触していないが、後述するように、平坦な底面１２ｄの全体が表面１６ｓと密接することが好ましい。ただし、この図示例から、振動盤１６と搬送振動体１２の寸法関係が多少変化しても、当該寸法関係に適合した形状のクランプ部材１８を用いることで両者の外周部を支障なく固定できることがわかる。   Due to the cross-sectional shape of the inner surface 12t, the outer peripheral portion 12b of the conveying vibration body 12 has a cross section in which the bottom side is thick in the radial direction and the top side is thin in the radial direction as a whole. Further, a flat bottom surface 12d (the above-described outer mounting surface) is provided on the bottom portion 12c of the outer peripheral portion 12b so as to protrude downward and is placed in close contact with the surface 16s of the outer peripheral portion of the diaphragm 16. Is formed). The bottom surface 12d is formed in an annular band shape with the axis 10x as the center, and is configured to be in close contact with the outer surface 16s of the diaphragm 16. In the present embodiment, the bottom surface 12d provided on the bottom portion 12c is formed only on the outer peripheral portion 12b, and the region on the inner side of the bottom surface 12d is configured such that the bottom surface shape of the inner bottom portion 12a is concave, so It is supposed not to touch. For this reason, since the rotational vibration of the vibration plate 16 is transmitted only from the bottom surface 12d provided on the outer periphery to the outer peripheral portion 12b of the conveying vibration body 12, the vibration is efficiently transferred to the conveying path 12w formed in the outer peripheral portion 12b. Can communicate. In the illustrated example, the outer edge of the bottom portion 12 c of the conveying vibration body 12 projects outward from the outer peripheral portion of the vibration plate 16, so a part of the outer side of the flat bottom surface 12 d contacts the surface 16 s of the vibration plate 16. However, as described later, it is preferable that the entire flat bottom surface 12d is in close contact with the surface 16s. However, from this illustrated example, even if the dimensional relationship between the vibration plate 16 and the conveyance vibrating body 12 changes somewhat, the outer peripheral portion of both can be fixed without hindrance by using the clamp member 18 having a shape suitable for the dimensional relationship. Recognize.

図４に示すように、搬送振動体１２の底部１２ｃの外縁、すなわち、底部外周縁には凹溝１２ｅが形成されている。この凹溝１２ｅは下方（振動盤１６）側に傾斜係合面１２ｆを備えた段部を含む。凹溝１２ｅ及び傾斜係合面１２ｆは図示例の場合には軸線１０ｘ回りに環状に形成されている。これにより搬送振動体１２の振動盤１６に対する取付角度位置が自由となるが、その必要性がなければ後述するクランプ構造に対応した角度位置にのみ形成されていてもよい。この場合に、凹溝１２ｅ及び傾斜係合面１２ｆは軸線１０ｘ周りの回転方向に見たときに平面視で軸線１０ｘを中心とする円弧状に伸びるように形成される。   As shown in FIG. 4, a concave groove 12 e is formed on the outer edge of the bottom portion 12 c of the conveying vibration body 12, that is, on the outer periphery of the bottom portion. The concave groove 12e includes a stepped portion having an inclined engagement surface 12f on the lower side (vibration plate 16) side. In the illustrated example, the concave groove 12e and the inclined engagement surface 12f are formed in an annular shape around the axis 10x. As a result, the mounting angular position of the conveying vibration body 12 with respect to the vibration plate 16 becomes free, but if there is no necessity, it may be formed only at an angular position corresponding to a clamp structure described later. In this case, the concave groove 12e and the inclined engagement surface 12f are formed so as to extend in an arc shape centered on the axis 10x in plan view when viewed in the rotation direction around the axis 10x.

上記の傾斜係合面１２ｆは半径方向外側に向くとともに斜め上方を向く面として構成される。すなわち、傾斜係合面１２ｆは軸線１０ｘの方向に対して傾斜して振動盤１６とは反対側に向くとともに、軸線１０ｘと直交する面（水平面）内においては三箇所のクランプ構造間でそれぞれ相互に異なる方向を向いた面となっている。図示例では三箇所のクランプ構造における各傾斜係合面１２ｆは上記水平面内でいずれも半径方向外側に向いているが、各クランプ構造の角度位置における半径方向外側は水平面内において相互に異なる向きであるので、結果として各傾斜係合面１２ｆの水平面内における向きは各クランプ構造間でいずれも異なるものとなる。なお、一般的には、複数のクランプ構造のうち少なくとも二つの傾斜係合面１２ｆについて水平面内における傾斜の向きが異なっていればよい。   The inclined engaging surface 12f is configured as a surface facing outward in the radial direction and facing obliquely upward. In other words, the inclined engagement surface 12f is inclined with respect to the direction of the axis 10x and faces the opposite side of the diaphragm 16, and in a plane (horizontal plane) orthogonal to the axis 10x, the three clamp structures are mutually connected. The surface is facing different directions. In the illustrated example, the inclined engagement surfaces 12f in the three clamp structures are all directed radially outward in the horizontal plane, but the radial outer sides in the angular positions of the clamp structures are different from each other in the horizontal plane. Therefore, as a result, the orientation of each inclined engagement surface 12f in the horizontal plane is different between the clamp structures. In general, it is only necessary that at least two inclined engagement surfaces 12f of the plurality of clamp structures have different inclination directions in the horizontal plane.

傾斜係合面１２ｆの水平面を基準とした傾斜角φは２０〜７０度の範囲内が好ましく、さらに３０〜６０度の範囲内であることがさらに好ましい。この傾斜角φは、搬送振動体１２が振動盤１６に固定された状態、すなわち、傾斜係合面１２ｆが後述するクランプ部材１８のクランプ爪１８ｂに設けられるクランプ面１８ｄと密接した状態での傾斜角であり、したがってこの状態におけるクランプ面１８ｄの傾斜角でもあって、この傾斜角φによりクランプ爪１８ｂによる固定力の方向が決定される。傾斜角φが上記角度範囲を逸脱した場合でも従来構造に比べると或る程度の効果が得られるが、当該固定力の向きが軸線方向（搬送振動体１２を振動盤１６に押し付ける方向）と半径方向のいずれかに偏るので、複数のクランプ構造間の向きの違いによって与えられる水平方向の固定力と、各クランプ構造において与えられる軸線方向（搬送振動体１２を振動盤１６に押し付ける方向）の固定力のうちいずれか一方が不十分になるか、或いは、これを回避するためにクランプ部材の締付トルクが過大になりやすい。   The inclination angle φ with respect to the horizontal plane of the inclined engagement surface 12f is preferably in the range of 20 to 70 degrees, and more preferably in the range of 30 to 60 degrees. This inclination angle φ is an inclination in a state where the conveying vibration body 12 is fixed to the diaphragm 16, that is, in a state where the inclined engagement surface 12 f is in close contact with a clamp surface 18 d provided on a clamp claw 18 b of a clamp member 18 described later. This is also the inclination angle of the clamp surface 18d in this state, and the direction of the fixing force by the clamp claw 18b is determined by this inclination angle φ. Even when the inclination angle φ deviates from the above angle range, a certain degree of effect can be obtained as compared with the conventional structure, but the direction of the fixing force is the axial direction (the direction in which the conveying vibrator 12 is pressed against the diaphragm 16) and the radius. Since it is biased to any one of the directions, the fixing force in the horizontal direction given by the difference in direction between the plurality of clamp structures and the fixation in the axial direction (direction in which the conveying vibrator 12 is pressed against the diaphragm 16) given in each clamp structure. Either one of the forces becomes insufficient or the tightening torque of the clamp member tends to be excessive in order to avoid this.

このとき、振動盤１６から搬送振動体１２へと与えられる回転振動は、部品搬送力を生じさせるために、軸線１０ｘを中心として回転する側に向けて斜め上方へ向かう振動方向を有する。このため、水平方向と軸線方向のうち一方の固定力が不足すると、振動盤と搬送振動体が当該一方の方向にずれやすくなるので、振動変位の搬送振動体への伝達効率が低下し、搬送効率が悪化するとともに、上記ずれによって不要振動が発生して部品が暴れやすくなる。特に、搬送速度を高めるために振動周波数を上昇させると、従来構造において用いられる各固定方向と直交する方向（半径方向の締付固定部では軸線方向、軸線方向の締付固定部では水平方向）の摩擦力に起因する固定作用はほとんど期待できなくなるため、振動の伝達ロスが大きくなって高速搬送が困難になるとともに不要な振動が発生して部品姿勢が安定しなくなる。 At this time, the rotational vibration applied from the vibration plate 16 to the conveyance vibrating body 12 has a vibration direction obliquely upward toward the side rotating about the axis 10x in order to generate a component conveyance force. Therefore, when a shortage of one of the fixing force of the horizontal direction and the axial direction, the vibration plate and the conveying vibrating body Reya becomes easier without the direction of the one, it decreases the transmission efficiency to the conveying vibrator of the vibration displacement Further, the conveyance efficiency is deteriorated, and unnecessary vibration is generated due to the above-described deviation, and the components are likely to be violated. In particular, when the vibration frequency is increased in order to increase the conveyance speed, the direction orthogonal to each fixing direction used in the conventional structure (in the axial direction in the radial fastening fixing portion, in the horizontal direction in the axial fastening fixing portion) Since the fixing action due to the frictional force is hardly expected, vibration transmission loss becomes large and high-speed conveyance becomes difficult, and unnecessary vibration occurs and the component posture becomes unstable.

振動盤１６の外周面には水平で半径方向に延びる軸線を備えたネジ穴１６ｂが形成され、このネジ穴１６ｂに螺合したボルト１９によりクランプ部材１８が振動盤１６の外周面上に締め付け固定されている。これらのネジ穴１６ｂ、クランプ部材１８及びボルト１９は、上記凹溝１２ｅ（段部）とともに本発明のクランプ構造を構成する。このクランプ構造は軸線１０ｘ周りの複数個所に設けられる。特に、水平方向に確実に固定するためには三箇所以上にクランプ構造を設けることが好ましい。図示例では、クランプ構造は軸線１０ｘ周りに等角度間隔で三箇所に設けられている。   A screw hole 16b having a horizontal and radially extending axis is formed on the outer peripheral surface of the vibration plate 16, and a clamp member 18 is fastened and fixed on the outer peripheral surface of the vibration plate 16 by a bolt 19 screwed into the screw hole 16b. Has been. These screw hole 16b, clamp member 18 and bolt 19 constitute the clamp structure of the present invention together with the concave groove 12e (stepped portion). This clamp structure is provided at a plurality of locations around the axis 10x. In particular, it is preferable to provide clamp structures at three or more locations in order to securely fix in the horizontal direction. In the illustrated example, the clamp structures are provided at three locations at equiangular intervals around the axis 10x.

クランプ部材１８は、上記ボルト１９を挿通する段付き孔構造を備えた固定孔１８ａを有し、この固定孔１８ａは半径方向の軸線を備えてクランプ部材１８を貫通している。固定孔１８ａの途中には半径方向外側に向いた段差部が設けられ、この段差部にボルト１９の頭部が係合することでボルト１９を振動盤１６のネジ穴１６ｂに螺合させて締め付けたときクランプ部材１８のクランプ面１８ｄが傾斜係合面１２ｆに押し付けられる。   The clamp member 18 has a fixing hole 18 a having a stepped hole structure through which the bolt 19 is inserted. The fixing hole 18 a has a radial axis and penetrates the clamp member 18. In the middle of the fixing hole 18a, a step portion facing outward in the radial direction is provided, and the head of the bolt 19 is engaged with the step portion so that the bolt 19 is screwed into the screw hole 16b of the diaphragm 16 and tightened. Then, the clamp surface 18d of the clamp member 18 is pressed against the inclined engagement surface 12f.

クランプ部材１８の上部（搬送振動体１２側の部分）には半径方向内側に突出するクランプ爪１８ｂが設けられ、このクランプ爪１８ｂには、上記凹溝１２ｅの傾斜係合面１２ｆと密接する前述のクランプ面１８ｄを備えた段部が形成されている。クランプ爪１８ｂ及びクランプ面１８ｄは、前述の凹溝１２ｅ及び傾斜係合面１２ｆに整合するように、軸線１０ｘ周りの回転方向に見たときに平面視で軸線１０ｘを中心とする逆円弧状に形成されている。   A clamp claw 18b protruding radially inward is provided on the upper portion of the clamp member 18 (portion on the conveying vibration body 12 side), and the clamp claw 18b is in close contact with the inclined engagement surface 12f of the concave groove 12e. A step portion having a clamping surface 18d is formed. The clamp claw 18b and the clamp surface 18d are formed in a reverse arc shape centered on the axis 10x in plan view when viewed in the rotation direction around the axis 10x so as to be aligned with the concave groove 12e and the inclined engagement surface 12f described above. Is formed.

クランプ部材１８の下部（搬送振動体１２とは反対側の部分）には半径方向内側に突出する係合爪１８ｃが設けられ、この係合爪１８ｃは振動盤１２の外周面と下面との間の角部に係合し、クランプ部材１８の搬送振動体１２の側の位置を規制している。すなわち、クランプ部材１８がボルト１９により振動盤１６の側に押し付けられた状態で係合爪１８ｃが振動盤１６に係合することによりクランプ部材１８の振動盤１６に対する搬送振動体１２の側（図示上方）への移動が規制される。なお、本実施形態では、クランプ構造は、振動盤１６において下方に突出する接続部１６ａを避けた角度位置（図示例では回転方向に複数設けられた接続部１６ａ間の角度の二等分線上の位置）に設けられている。これによって、上記係合爪１８ｃを接続部１６ａに妨げられずに振動盤１６の外周面の下側の角部に係合させることができる。   An engaging claw 18c that protrudes inward in the radial direction is provided at a lower portion of the clamp member 18 (a portion opposite to the conveying vibration body 12). The engaging claw 18c is provided between the outer peripheral surface and the lower surface of the vibration plate 12. The position of the clamp member 18 on the side of the conveying vibration body 12 is restricted. That is, when the clamp member 18 is pressed against the vibration plate 16 by the bolt 19, the engaging claw 18 c is engaged with the vibration plate 16, whereby the clamp member 18 is moved to the conveying vibration body 12 side (illustrated). (Upward) movement is restricted. In the present embodiment, the clamp structure has an angular position on the vibration plate 16 that avoids the connecting portion 16a protruding downward (in the illustrated example, on the bisector of the angle between the connecting portions 16a that are provided in the rotational direction. Position). Thus, the engaging claw 18c can be engaged with the lower corner of the outer peripheral surface of the diaphragm 16 without being obstructed by the connecting portion 16a.

上記の構成により、クランプ部材１８はボルト１９によって振動盤１６の外周部に対して半径方向に移動可能に取り付けられる。これによって、クランプ部材１８を搬送振動体１２の底部外周縁に対して容易に係合させたり取り外したりすることができるとともに、搬送振動体１２に対する締付固定力を調整することも可能である。例えば、クランプ部材１８の固定孔１８ａにボルト１９を挿通させてボルト１９をネジ穴１６ｂに螺合させていくことで、ボルト１９でクランプ部材１８を締め付け、クランプ部材１８のクランプ爪１８ｂが凹溝１２ｅに係合し、クランプ面１８ｄを傾斜係合面１２ｆに密接させることができる。この場合に、振動盤１６の外周部とクランプ部材１８の間隔は、クランプ爪１８ｂが凹溝１２ｅに充分に押し付けられることで搬送振動体１２が半径方向内側に固定力を受けて確実に位置決めされるとともに下方に固定力を受けて振動盤１２に確実に押し付けられた状態にすることができるように設定される。なお、当該状態になったときに、図示のようにクランプ部材１８の内周面が振動盤１２の外周面に当接するように構成されることが、クランプ構造の取付安定性を高める上で好ましい。   With the above configuration, the clamp member 18 is attached to the outer peripheral portion of the vibration plate 16 by the bolt 19 so as to be movable in the radial direction. Accordingly, the clamp member 18 can be easily engaged with or removed from the outer peripheral edge of the bottom of the conveying vibration body 12, and the tightening fixing force with respect to the conveying vibration body 12 can be adjusted. For example, by inserting the bolt 19 into the fixing hole 18a of the clamp member 18 and screwing the bolt 19 into the screw hole 16b, the clamp member 18 is tightened with the bolt 19, and the clamp claw 18b of the clamp member 18 is recessed. The clamp surface 18d can be brought into close contact with the inclined engagement surface 12f. In this case, the distance between the outer peripheral portion of the vibration plate 16 and the clamp member 18 is ensured that the conveying vibration body 12 receives the fixing force radially inwardly when the clamp claw 18b is sufficiently pressed against the concave groove 12e. In addition, the fixing force is set downward so as to be surely pressed against the diaphragm 12. It is preferable that the inner peripheral surface of the clamp member 18 is in contact with the outer peripheral surface of the vibration plate 12 as shown in the drawing in order to increase the mounting stability of the clamp structure. .

本実施形態では、図２（ａ）及び（ｂ）に示すように三箇所に形成されたクランプ構造が全て同一構造（回転対称性を有する構造）を有するものとなっている。そして、これらのクランプ構造が軸線１０ｘ回りに等角度（１２０度）間隔で設けられている。各クランプ構造においてはボルト１９を回転させることでクランプ部材１８が振動盤１６に対して半径方向に移動可能に構成されるが、そのうちの一つのクランプ構造のみにおいてボルト１９を緩めてクランプ部材１８を半径方向に移動させることで、他の二つのクランプ構造ではボルト１９を操作することなく搬送振動体１２を振動盤１６上から取り外すことができる。また、予め二つのクランプ構造において振動盤１６に対するボルト１９の螺合深さが設定されてあれば、残り一つのクランプ構造においてボルト１９が緩められた状態で残りの二つのクランプ部材１８のクランプ爪１８ｂに嵌合させる態様で搬送振動体１２を振動盤１２上に載置した後、当該一つのクランプ構造のボルト１９を締め付けるだけで搬送振動体１２を振動盤１６上に固定することが可能になる。これは、各クランプ構造はクランプ面１８ｄで傾斜係合面１２ｆを傾斜した向きに押さえ付けているだけであり、従来構造のように直接の締付固定構造や挟持した固定構造を用いて固定しているわけではないので、一部のクランプ構造の操作のみで全てのクランプ構造の固定状態の設定と解除を行うことができるからである。一般的には少なくとも一つのクランプ構造のクランプ部材を移動させずに着脱作業を行うことができる。ただし、本実施形態のように一つのクランプ構造の操作のみで残りの二つ以上のクランプ構造を操作しなくても着脱作業ができるように構成することは容易である。なお、この場合に、移動操作（螺合操作）を要するクランプ部材を有するクランプ構造を除いた残りのクランプ構造においてはボルトを操作する必要がないことから、クランプ部材１８を振動盤１６に対して移動できない構造（固定位置にのみ取付できる構造）で取り付けてもよい。   In this embodiment, as shown to Fig.2 (a) and (b), all the clamp structures formed in three places have the same structure (structure which has rotational symmetry). These clamp structures are provided at equiangular intervals (120 degrees) around the axis 10x. In each clamp structure, the clamp member 18 is configured to be movable in the radial direction with respect to the diaphragm 16 by rotating the bolt 19. However, in only one of the clamp structures, the bolt 19 is loosened and the clamp member 18 is moved. By moving in the radial direction, the transport vibrator 12 can be removed from the vibration plate 16 without operating the bolt 19 in the other two clamp structures. If the screwing depth of the bolt 19 with respect to the diaphragm 16 is set in advance in the two clamp structures, the clamp claws of the remaining two clamp members 18 with the bolt 19 loosened in the remaining one clamp structure. After the conveying vibration body 12 is placed on the vibration plate 12 in such a manner as to be fitted to 18b, the conveyance vibration member 12 can be fixed on the vibration plate 16 simply by tightening the bolt 19 of the one clamp structure. Become. This is because each clamp structure only presses the inclined engagement surface 12f in the inclined direction with the clamp surface 18d, and is fixed using a direct clamping fixing structure or a sandwiched fixing structure like the conventional structure. This is because the fixed state of all the clamp structures can be set and released only by operating a part of the clamp structures. In general, the attaching / detaching operation can be performed without moving the clamp member of at least one clamp structure. However, as in this embodiment, it is easy to configure so that the attaching / detaching operation can be performed only by operating one clamp structure without operating the remaining two or more clamp structures. In this case, in the remaining clamp structures except for the clamp structure having a clamp member that requires a moving operation (screwing operation), it is not necessary to operate the bolt. You may attach by the structure (structure which can be attached only to a fixed position) which cannot move.

以上説明した本実施形態では、搬送振動体１２の外周部１２ｂに設けられた底部１２ｃが振動盤１６の外周部の表面１６ｓ上に載置されるとともに、底部１２ｃに形成された凹溝１２ｅにクランプ部材１８のクランプ爪１８ｂが係合し、傾斜係合面１２ｆとクランプ面１８ｄが密接することで、搬送振動体１２が振動盤１６上に固定される。したがって、クランプ作用による固定力は搬送振動体１２を振動盤１６に対して軸線（垂直）方向に押し付けるだけでなく半径方向内側に向けても加わるため、三箇所のクランプ構造における水平方向の固定力が相互に異なる向きに与えられることになる。このため、搬送振動体１２は水平方向と軸線方向の双方に固定されることとなるから、水平方向と軸線方向の少なくともいずれか一方を摩擦力に頼っていた従来構造に比べると、振動盤１６の回転振動を効率的かつ高精度に搬送振動体１２に伝達させることができ、また、搬送振動体１２に不要な振動が発生することも防止でき、騒音も低減できる。   In the present embodiment described above, the bottom portion 12c provided on the outer peripheral portion 12b of the conveying vibration body 12 is placed on the surface 16s of the outer peripheral portion of the vibration plate 16, and the concave groove 12e formed on the bottom portion 12c. The clamp claw 18b of the clamp member 18 is engaged, and the inclined engagement surface 12f and the clamp surface 18d are in close contact with each other, whereby the conveyance vibrating body 12 is fixed on the vibration plate 16. Accordingly, the fixing force due to the clamping action is not only pressed in the axial (vertical) direction against the vibration plate 16 in the axial (vertical) direction but also inward in the radial direction, so that the horizontal fixing force in the three clamp structures is applied. Are given in different directions. For this reason, since the conveyance vibrating body 12 is fixed in both the horizontal direction and the axial direction, the vibration plate 16 is compared with the conventional structure in which at least one of the horizontal direction and the axial direction depends on the frictional force. Can be efficiently and highly accurately transmitted to the conveying vibration body 12, and unnecessary vibration can be prevented from occurring in the conveying vibration body 12, and noise can be reduced.

より詳細に述べると、本実施形態の部品搬送装置１０においては、回転振動機１１によって水平面（軸線１０ｘと直交する面）に対して斜め方向の回転振動が発生し、この回転振動を搬送振動体１２に与えるようになっているが、従来の外周部による固定方法のうち、搬送振動体を振動盤に対して軸線方向の締付により固定する場合には、軸線（垂直）方向の振動成分を効率的に伝達することはできるものの、両者間に水平方向のずれが生ずる可能性があり、このために効率的な搬送が困難になり搬送速度を高めることができなくなり、部品の暴れや騒音が発生する虞もある。また、搬送振動体を振動盤に対して半径方向の締付により固定する場合には、軸線方向にずれが生ずる可能性があり、このためにやはり効率的に振動を伝達することができず搬送速度を高めることが難しく、部品の暴れや騒音が発生する虞もある。   More specifically, in the component conveying apparatus 10 of the present embodiment, rotational vibration in an oblique direction is generated with respect to a horizontal plane (a plane orthogonal to the axis 10x) by the rotary vibrator 11, and this rotational vibration is transferred to the conveying vibrator. In the conventional fixing method using the outer peripheral portion, when the conveying vibrator is fixed to the diaphragm by axial tightening, the vibration component in the axial (vertical) direction is Although it can be transmitted efficiently, there is a possibility of horizontal displacement between the two, which makes it difficult to transport efficiently and makes it impossible to increase the transport speed, resulting in component fluctuations and noise. There is also a risk of occurrence. In addition, when the conveying vibrator is fixed to the vibration plate by radial tightening, there is a possibility that a deviation occurs in the axial direction. It is difficult to increase the speed, and there is a risk that parts may be violated and noise may occur.

これに対して本実施形態のクランプ構造では、複数のクランプ構造において水平面内において相互に異なる向きに設定されるとともに軸線方向に対して傾斜した方向に締付力を与えることにより、搬送振動体１２を振動盤１６に対して水平方向と軸線方向に共に確実に固定することができるため、回転振動を振動盤１６から確実かつ高精度に搬送振動体１２に伝達することができるので、特に高周波数で部品を高速搬送する場合に効率的な搬送態様を実現でき、搬送速度の高速化や部品の暴れ防止を図ることができ、なおかつ騒音も低減できる。また、前述のように、各クランプ構造においては傾斜係合面１２ｆにクランプ面１８ｄが密接した状態となるように軸線１０ｘの方向に対し斜めの向きに押し当てるだけでよく、水平面内で相互に異なる向きに設定された傾斜係合面１２ｆを有する複数のクランプ構造を設けることにより搬送振動体１２を振動盤１６に固定しているので、ボルトによる螺合構造で半径方向若しくは軸線方向に直接固定する従来方法に比べると、着脱作業が容易になるという利点もある。特に、クランプ部材１８により搬送振動体１２に対して半径方向内側に締付応力を与える構造とすることによって、クランプ構造も簡易になり、着脱作業もさらに容易になる。また、軸線方向と水平方向の固定作用を同一箇所で与えることができることから、搬送振動体１２内に生ずる不要振動を抑制できるという効果も得られる。さらに、クランプ部材１８を用いることで搬送振動体１２と振動盤１６の固定構造部分の自由度が高くなり、しかも傾斜係合面１２ｆを用いることで軸線１０ｘ方向の締付固定に用いる水平面を形成する場合よりも面近傍部分の剛性を高めることが容易になるため、固定部分の構造の簡易化や剛性の確保、加工コストの低減などを図ることが可能になるという有利な点がある。   On the other hand, in the clamp structure of the present embodiment, the conveying vibrator 12 is set in a plurality of clamp structures in different directions in the horizontal plane and by applying a tightening force in a direction inclined with respect to the axial direction. Can be reliably fixed to the vibration plate 16 both in the horizontal direction and in the axial direction, so that the rotational vibration can be transmitted from the vibration plate 16 to the conveying vibration body 12 with high accuracy. Therefore, an efficient conveyance mode can be realized when parts are conveyed at high speed, the conveyance speed can be increased, the parts can be prevented from being violated, and noise can be reduced. Further, as described above, in each clamp structure, it is only necessary to press in an oblique direction with respect to the direction of the axis 10x so that the clamp surface 18d is in close contact with the inclined engagement surface 12f. Since the conveying vibration body 12 is fixed to the vibration plate 16 by providing a plurality of clamp structures having inclined engagement surfaces 12f set in different directions, it is directly fixed in the radial direction or the axial direction by a screwed structure using bolts. Compared to the conventional method, there is an advantage that the attaching / detaching work becomes easy. In particular, by using a structure in which a clamping stress is applied to the conveying vibration body 12 in the radial direction by the clamp member 18, the clamp structure can be simplified and the attaching / detaching operation can be further facilitated. Further, since the fixing action in the axial direction and the horizontal direction can be given at the same place, an effect of suppressing unnecessary vibration generated in the conveying vibration body 12 is also obtained. Furthermore, the use of the clamp member 18 increases the degree of freedom of the fixing structure portion of the conveying vibrator 12 and the vibration plate 16, and the inclined engagement surface 12f forms a horizontal plane used for fastening fixation in the direction of the axis 10x. Since it becomes easier to increase the rigidity in the vicinity of the surface than in this case, there is an advantage that it is possible to simplify the structure of the fixed portion, secure the rigidity, and reduce the processing cost.

一方、本実施形態の部品搬送装置１０を図１０に示す固定方法と比較した場合には、以下のような点で有利な効果が得られる。図１０に示す固定方法では、搬送振動体２の中心部をボルト３により固定しているだけであるので、振動盤１ａから受ける回転振動によって搬送振動体２の変形により搬送振動体２の外周部に不要な振動モードが発生し、これによって効率的な部品搬送ができなかったり、部品が搬送中に暴れたり、騒音が発生したりするなどの不具合が生ずる。また、搬送振動体２は振動盤１ａに対して回転方向には中心部における摩擦力のみで固定されているので、振動周波数が高くなると回転方向の振動成分が固定部分で吸収されやすくなり、振動の伝達効率が著しく低下する。これに対して、本実施形態では、搬送振動体１２の底部外側に振動盤１６の表面１６ｓ上に載置される外側載置面（底面１２ｄ）を設けるとともに振動盤１６の外周部を搬送振動体１２の外周部１２ｂにクランプ構造によって固定しているので、回転振動が振動盤１６の外周部からこれに接触する底部１２ｃを備えた外周部１２ｂに形成される搬送路１２ｗへと軸線方向に伝達されるため、搬送路１２ｗの振動態様が振動盤１６の振動態様に近くなり、振動伝達を効率的かつ高精度に行うことができる。したがって、部品を高速かつ安定して搬送することができ、部品に与えられる搬送力が不足したり、部品が搬送路１２ｗ上で暴れたりすることを防止でき、騒音が生ずることも防止できる。また、振動盤１６の外周部が搬送振動体１２の外周部１２ｂに固定されることで、搬送振動体１２の内周部の軽量化が可能となるために高速搬送がさらに容易になる。   On the other hand, when the component conveying apparatus 10 of this embodiment is compared with the fixing method shown in FIG. 10, advantageous effects are obtained in the following points. In the fixing method shown in FIG. 10, since the center portion of the conveyance vibrating body 2 is only fixed by the bolt 3, the outer peripheral portion of the conveyance vibrating body 2 is deformed by the rotation vibration received from the vibration plate 1 a due to the deformation of the conveyance vibrating body 2. Unnecessary vibration modes are generated in this way, which causes problems such as inability to efficiently carry parts, rampage of parts during transportation, and noise. Further, since the conveyance vibrator 2 is fixed only to the frictional force at the center in the rotational direction with respect to the vibration plate 1a, when the vibration frequency is increased, the vibration component in the rotational direction is easily absorbed by the fixed portion, and vibration is generated. The transmission efficiency is significantly reduced. On the other hand, in the present embodiment, an outer placement surface (bottom surface 12d) that is placed on the surface 16s of the vibration plate 16 is provided outside the bottom portion of the conveyance vibration body 12, and the outer peripheral portion of the vibration plate 16 is conveyed and vibrated. Since it is fixed to the outer peripheral portion 12b of the body 12 by a clamp structure, the rotational vibration is axially moved from the outer peripheral portion of the vibration plate 16 to the conveying path 12w formed in the outer peripheral portion 12b having the bottom portion 12c in contact therewith. Since the vibration is transmitted, the vibration mode of the conveyance path 12w is close to the vibration mode of the vibration plate 16, and the vibration can be transmitted efficiently and with high accuracy. Accordingly, the parts can be conveyed at high speed and stably, the conveyance force applied to the parts can be prevented from being insufficient, the parts can be prevented from being violated on the conveyance path 12w, and noise can be prevented from being generated. Further, since the outer peripheral portion of the vibration plate 16 is fixed to the outer peripheral portion 12b of the transport vibration body 12, the inner peripheral portion of the transport vibration body 12 can be reduced in weight, so that high-speed transport is further facilitated.

また、本実施形態では、クランプ部材１８に係合爪１８ｂが設けられ、この係合爪１８ｂが振動盤１６の表面１６ｓとは反対側の角部に係合することにより、クランプ部材１８の移動が振動盤１６に対して搬送振動体１２の側に規制されるため、クランプ部材１８によるクランプ状態を確実かつ安定的に（再現性良く）実現することができる。   In the present embodiment, the clamp member 18 is provided with an engagement claw 18b, and the engagement claw 18b engages with a corner portion on the opposite side of the surface 16s of the vibration plate 16, thereby moving the clamp member 18. Therefore, the clamp state by the clamp member 18 can be reliably and stably realized (with good reproducibility).

さらに、本実施形態では、回転振動機１１において回転方向に三つの加振機構２０が等角度間隔で設置され、これらの加振機構２０が回転方向に等角度間隔で設けられた三箇所で振動盤１６を駆動して回転振動を発生させるとともに、振動盤１６と搬送振動体１２が回転方向に等角度間隔で設けられる三箇所でクランプ構造により固定されるので、各クランプ構造に加わる回転振動に伴う応力を均等に負担することができ、回転振動の伝達態様を安定させることができる。   Furthermore, in this embodiment, in the rotary vibrator 11, three vibration mechanisms 20 are installed at equal angular intervals in the rotation direction, and these vibration mechanisms 20 vibrate at three locations provided at equal angular intervals in the rotation direction. The panel 16 is driven to generate rotational vibration, and the vibration panel 16 and the conveying vibration body 12 are fixed by the clamp structure at three positions provided at equal angular intervals in the rotation direction. The accompanying stress can be borne evenly, and the transmission mode of rotational vibration can be stabilized.

次に、図５を参照して本発明に係る第２実施形態について説明する。本実施形態では、図５に示すクランプ構造及びその近傍の構成のみが上記第１実施形態と異なるだけであり、他の構成は第１実施形態と同様であるので、同様の部分については説明を省略する。   Next, a second embodiment according to the present invention will be described with reference to FIG. In this embodiment, only the clamp structure shown in FIG. 5 and the configuration in the vicinity thereof are different from those of the first embodiment, and other configurations are the same as those of the first embodiment. Omitted.

本実施形態では、振動盤１６の外周部に形成されたネジ穴１６ｂにボルト１９′を螺合させてクランプ部材１８′を取り付けるとともに、クランプ部材１８′のクランプ爪１８ｂ′により搬送振動体１２の外周部１２ｂを固定している点で第１実施形態と同様であるが、クランプ部材１８′自体の構造が異なる。クランプ部材１８′には第１実施形態の係合爪１８ｃは設けられていない。これによってクランプ部材１８′は上記接続部１６ａ上の角度位置にも取り付けることができるようになっている。   In the present embodiment, a bolt 19 ′ is screwed into a screw hole 16 b formed in the outer peripheral portion of the vibration plate 16 to attach a clamp member 18 ′, and the clamp vibration member 12 ′ of the clamp member 18 ′ uses the clamp claw 18 b ′. Although it is the same as that of 1st Embodiment by the point which has fixed the outer peripheral part 12b, the structure of clamp member 18 'itself differs. The clamp member 18 'is not provided with the engaging claw 18c of the first embodiment. As a result, the clamp member 18 'can be attached to the angular position on the connecting portion 16a.

また、本実施形態では、上記ネジ穴１６ｂの雌ネジが形成されている部分とは軸線方向に異なる位置である開口側に、雌ネジの設けられていない円筒内面を備えたガイド孔部１６ｂ′（上記ガイド部に相当する。）が形成されている。一方、ボルト１９′には、ネジ穴１６ｂの雌ネジに対応する雄ネジ１９ａ′が設けられている部分とは軸線方向の異なる位置である頭部１９ｂ′側に、雄ネジの設けられていない円筒外面を備えた位置決め軸部１９ｃ′（上記位置決め部に相当する。）が形成されている。ボルト１９′をネジ穴１６ｂに螺合させると、上記のガイド孔部１６ｂ′に位置決め軸部１９ｃ′が導入され、ボルト１９′と振動盤１６とが必要な位置決め精度で位置決めされるようになっている。また、位置決め軸部１９ｃ′はクランプ部材１８′に設けられた固定孔１８ａに挿通されるが、このとき、位置決め軸部１９ｃによってボルト１９′とクランプ部材１８′とが必要な位置決め精度で位置決めされるようになっている。したがって、クランプ部材１８′は、上記位置決め軸部１９ｃを介して振動盤１６に対して必要な位置精度で軸線方向に保持される。これによって、クランプ爪１８ｂ′の凹溝１２ｅに対する軸線方向の位置精度を容易に確保できるので、搬送振動体１２を確実にかつ安定して（再現性良く）振動盤１６に固定できる。   Further, in the present embodiment, the guide hole 16b ′ having a cylindrical inner surface not provided with a female screw on the opening side which is a position different from the portion where the female screw of the screw hole 16b is formed in the axial direction. (Corresponding to the guide portion). On the other hand, the bolt 19 'is not provided with a male screw on the head 19b' side, which is a position different from the portion where the male screw 19a 'corresponding to the female screw of the screw hole 16b is provided in the axial direction. A positioning shaft portion 19c ′ (corresponding to the positioning portion) having a cylindrical outer surface is formed. When the bolt 19 'is screwed into the screw hole 16b, the positioning shaft portion 19c' is introduced into the guide hole portion 16b 'so that the bolt 19' and the vibration plate 16 are positioned with the required positioning accuracy. ing. Further, the positioning shaft portion 19c 'is inserted through a fixing hole 18a provided in the clamp member 18'. At this time, the bolt 19 'and the clamp member 18' are positioned with the required positioning accuracy by the positioning shaft portion 19c. It has become so. Accordingly, the clamp member 18 'is held in the axial direction with the required positional accuracy with respect to the vibration plate 16 via the positioning shaft portion 19c. As a result, the positional accuracy in the axial direction of the clamp claw 18b ′ with respect to the concave groove 12e can be easily secured, so that the conveying vibrator 12 can be fixed to the diaphragm 16 reliably and stably (with good reproducibility).

なお、本実施形態では、搬送振動体１２の底面１２ｄの全面が振動盤１６の表面１６ｓ上に接触しているので、搬送振動体１２が振動盤１６上により安定した状態で載置される。そして、この構造に対応させて、クランプ部材１８′のクランプ爪１８ｂ′の半径方向内側への突出量を大きくし、クランプ爪１８ｂ′が凹溝１２ｅに到達するように構成している。ただし、図示点線で示すように、搬送振動体１２の底部外周縁を振動盤１６より外周側に張り出させ、これに対応するクランプ爪と係合するように構成しても構わない。   In the present embodiment, since the entire bottom surface 12d of the transport vibration body 12 is in contact with the surface 16s of the vibration plate 16, the transport vibration body 12 is placed on the vibration plate 16 in a more stable state. Corresponding to this structure, the amount of protrusion of the clamp claw 18b inward in the radial direction of the clamp claw 18b 'is increased so that the clamp claw 18b' reaches the concave groove 12e. However, as indicated by a dotted line in the figure, the outer peripheral edge of the bottom portion of the conveying vibration body 12 may protrude from the vibration plate 16 to the outer peripheral side, and may be configured to engage with the corresponding clamp claw.

次に、図６を参照して本発明に係る第３実施形態について説明する。本実施形態でも、図６に示すクランプ構造及びその近傍の構成のみが上記第１実施形態と異なるだけであり、他の構成は第１実施形態と同様であるので、同様の部分については説明を省略する。   Next, a third embodiment according to the present invention will be described with reference to FIG. Also in this embodiment, only the clamp structure shown in FIG. 6 and the configuration in the vicinity thereof are different from those of the first embodiment, and other configurations are the same as those of the first embodiment. Omitted.

本実施形態では、搬送振動体１２の振動盤１６′上に載置される底面１２ｄよりも外周側に底部外周縁を張り出させ、ここに凹溝１２ｅを形成している。そして、搬送振動体１２の凹溝１２ｅの形成された底部外周縁の形状に合わせて、クランプ爪１８ｂ″を振動盤１６′から外周側に離間した位置に備えたクランプ部材１８″を設けている。このように、組み合わされる振動盤１６′と搬送振動体１２の形状に応じてクランプ部材を形成することで、種々の組み合わせに容易に対応することができる。なお、本実施形態のクランプ部材１８″には第１実施形態と同様に係合爪１８ｃ″が形成され、この係合爪１８ｃ″は振動盤１６′の下方の角部に係合している。この係合爪１８ｃ″を設けることで、搬送振動体１２の外周縁が振動盤１６の外周面より外側に張り出していても安定したクランプ状態を実現できる。   In the present embodiment, the outer peripheral edge of the bottom is projected to the outer peripheral side of the bottom surface 12d placed on the vibration plate 16 'of the conveying vibration body 12, and the concave groove 12e is formed here. A clamp member 18 ″ having a clamp claw 18b ″ at a position spaced from the diaphragm 16 ′ on the outer peripheral side is provided in accordance with the shape of the outer periphery of the bottom portion where the concave groove 12e of the conveying vibration body 12 is formed. . In this way, by forming the clamp member in accordance with the shapes of the diaphragm 16 ′ and the conveyance vibrator 12 to be combined, various combinations can be easily handled. The clamp member 18 ″ of this embodiment is formed with an engaging claw 18c ″ as in the first embodiment, and this engaging claw 18c ″ is engaged with a lower corner of the diaphragm 16 ′. By providing the engaging claw 18c ″, a stable clamp state can be realized even if the outer peripheral edge of the conveying vibration body 12 projects outward from the outer peripheral surface of the vibration plate 16.

ところで、上記実施形態では図２（ｂ）に示すように傾斜係合面１２ｆ及びクランプ面１８ｄが水平面内で軸線１０ｘを中心とした回転方向Ｒに沿って形成されているが、図２（ｃ）又は（ｄ）に示すように傾斜係合面１２ｆ及びクランプ面１８ｄを当該回転方向Ｒと交差する態様で形成してもよい。ここで、図２（ｃ）に示す構成は、水平面内における傾斜係合面１２ｆ及びクランプ面１８ｄが軸線１０ｘを向いてはいるものの平坦に構成されることで円弧状の回転方向Ｒと交差している例である。また、図２（ｄ）に示す構成は、水平面内における傾斜係合面１２ｆ及びクランプ面１８ｄが軸線１０ｘとは異なる方位を向くことで回転方向Ｒと交差している例（図示例では水平面内で平坦な面となっているが円弧状の面であってもよい。）である。これらの場合に、複数のクランプ構造のうち少なくとも一つのクランプ構造において、水平面内における傾斜係合面１２ｆ及びクランプ面１８ｄが上記回転方向Ｒに対して交差するように構成することで、搬送振動体１２が振動盤１６に対し回転方向Ｒに対しても少なくとも斜めに向いた面の密接により固定されるので、回転方向Ｒに対する固定力をさらに増強することができるから、本発明の効果をさらに高めることが可能である。なお、この場合には、少なくとも二つのクランプ構造間で交差角その他の回転方向Ｒに対する交差態様が異なるように構成することがさらに好ましい。また、以上の説明は傾斜係合面１２ｆが水平面内で半径方向外側に向き、クランプ面１８ｄが水平面内で半径方向内側に向く例を示すものであるが、逆に傾斜係合面１２ｆが半径方向内側に向き、クランプ面１８ｄが半径方向外側に向くように構成することも可能である。   By the way, in the said embodiment, as shown in FIG.2 (b), although the inclination engagement surface 12f and the clamp surface 18d are formed along the rotation direction R centering on the axis line 10x within a horizontal surface, FIG. ) Or (d), the inclined engagement surface 12f and the clamp surface 18d may be formed in a manner that intersects with the rotation direction R. Here, the configuration shown in FIG. 2 (c) intersects the arcuate rotation direction R because the inclined engagement surface 12f and the clamp surface 18d in the horizontal plane are flat although they face the axis 10x. This is an example. In addition, the configuration shown in FIG. 2D is an example in which the inclined engagement surface 12f and the clamp surface 18d in the horizontal plane intersect the rotational direction R by being directed in a different direction from the axis 10x (in the horizontal plane in the illustrated example). However, it may be an arcuate surface. In these cases, in at least one of the plurality of clamp structures, the inclined engaging surface 12f and the clamp surface 18d in the horizontal plane are configured to intersect the rotational direction R, thereby conveying the vibrating body. Since 12 is fixed to the vibration plate 16 by close contact with at least the surface facing obliquely with respect to the rotational direction R, the fixing force in the rotational direction R can be further increased, and the effect of the present invention is further enhanced. It is possible. In this case, it is more preferable that the crossing angle and other crossing modes with respect to the rotation direction R are different between at least two clamp structures. Further, the above description shows an example in which the inclined engagement surface 12f is directed radially outward in the horizontal plane and the clamp surface 18d is directed radially inward in the horizontal plane. It is also possible to configure so that the clamp surface 18d faces inward in the direction and radially outward.

なお、発明者が図１０に示される従来の部品搬送装置と上記第１実施形態の部品搬送装置１０とを同じ振動周波数で駆動したところ、全体として部品搬送装置１０の方が高い搬送速度を示すとともに搬送姿勢も保たれることが確認された。特に、圧電駆動体２２に対する駆動電圧を高めて回転振動の振幅を大きくすると、従来の部品搬送装置では騒音が大きくなるとともに搬送路上の部品が暴れて整列させにくくなるとともに効率的に移動しなくなるという問題点が生じたが、部品搬送装置１０では騒音はほとんど発生しないとともに部品が暴れることもなく、搬送速度がさらに高くなることがわかった。比較した両部品搬送装置は縦横高さがそれぞれ０．２〜１．５ｍｍ程度の微細な部品（例えばＬＥＤチップなど）を搬送するための小型の装置である。また、部品搬送装置１０は従来の装置に比べて搬送速度を１．５〜２倍程度にまで高めることが可能であり、駆動電圧を従来の装置より低くしても良好な搬送速度を得ることができた。   When the inventor drives the conventional component conveying device shown in FIG. 10 and the component conveying device 10 of the first embodiment at the same vibration frequency, the component conveying device 10 as a whole exhibits a higher conveying speed. At the same time, it was confirmed that the transport posture was also maintained. In particular, when the driving voltage for the piezoelectric driving body 22 is increased to increase the amplitude of the rotational vibration, the conventional component conveying device increases the noise, and the components on the conveying path become violent and difficult to align and cannot move efficiently. Although a problem occurred, it has been found that the component conveying apparatus 10 generates almost no noise and the components are not violated, thereby further increasing the conveying speed. Both compared parts conveying apparatuses are small apparatuses for conveying fine parts (for example, LED chips, etc.) each having a height and width of about 0.2 to 1.5 mm. In addition, the component conveying apparatus 10 can increase the conveying speed to about 1.5 to 2 times that of the conventional apparatus, and can obtain a good conveying speed even if the drive voltage is lower than that of the conventional apparatus. I was able to.

尚、本発明の部品搬送装置は、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、上記各実施形態では、振動盤１６の外周部にボルト１９等でクランプ部材１８を取り付けるとともに、搬送振動体１２の外周底部にクランプ部材１８のクランプ面１８ｄが係合する傾斜係合面１２ｆを形成しているが、これとは逆に、搬送振動体１２の外周底部にボルト等でクランプ部材を取り付けるとともに振動盤１６の外周部にクランプ面が係合する傾斜係合面を形成してもよい。また、上記実施形態では傾斜係合面１２ｆはいずれも水平面内において半径方向外側に向いているが、複数のクランプ構造の少なくとも二つのクランプ部材間で傾斜係合面１２ｆが相互に異なる向きとなっていればよく、したがって、個々の傾斜係合面１２ｆについては水平面内において半径方向内側に向いていても、或いは、その他の方向を向いていてもよい。   In addition, the components conveying apparatus of this invention is not limited only to the above-mentioned illustration example, Of course, it can add various changes within the range which does not deviate from the summary of this invention. For example, in each of the above-described embodiments, the clamp member 18 is attached to the outer peripheral portion of the vibration plate 16 with a bolt 19 or the like, and the inclined engagement surface 12f with which the clamp surface 18d of the clamp member 18 is engaged with the outer peripheral bottom portion of the conveying vibration body 12. In contrast to this, a clamp member is attached to the outer peripheral bottom of the conveying vibration body 12 with a bolt or the like, and an inclined engagement surface is formed on the outer peripheral portion of the vibration plate 16 to engage the clamp surface. Also good. In the above embodiment, the inclined engagement surfaces 12f are all directed radially outward in the horizontal plane, but the inclined engagement surfaces 12f are different from each other between at least two clamp members of the plurality of clamp structures. Therefore, the individual inclined engagement surfaces 12f may be directed radially inward in the horizontal plane, or may be directed in other directions.
