Description of the Invention: [Technical Field] The present invention relates to a rotary vibration machine and a vibration type transmission device using the same, particularly relating to a drive mechanism of a rotary vibration machine. [Prior Art] In a vibrating transport device such as a bowl-type component feeder having a spiral track, a rotary vibrating machine for vibrating the bowl-shaped transport body in a tangential direction is generally used. This rotary vibrating machine has a vibrating plate which is sturdy on the base by an elastic branch such as a leaf spring. The vibrating plate is oscillated in a tangential direction around the axis by an electromagnetic driving body or a piezoelectric driving body. In recent years, a piezoelectric actuator supported on a base is connected to the vibrating plate via an elastic member such as a leaf spring, and the vibrating plate is vibrated in a tangential direction by the flexural vibration of the piezoelectric actuator. The above-described rotary vibrating machine using a piezoelectric actuator is as described in the following Patent Documents 1 to 3. The rotary vibration machine has a structure in which a piezoelectric actuator that is fixed to the upper side of the base σ extends toward the outer peripheral side in the radial direction, and the outer peripheral portion of the piezoelectric actuator is connected to the elastic member, and the elastic member is fixedly connected. Outside the vibrating plate. As described above, in the horizontal rotary vibrating machine in which the piezoelectric actuator extends toward the outer peripheral side in the radial direction, it has an advantage that the vibration can be efficiently tangentially lowered while the height can be lowered to constitute a small rotary vibrating machine.

No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The increase, therefore, increases the durability of the piezoelectric actuator due to the piezoelectric drive-° dynamic load. Further, in the horizontal rotary vibrating machine, a large amplitude is required at a high frequency such as a bowl-type conveying body to which a vibrating conveying device is fixed to the vibrating plate, so if _: as described above, there is a vibrating plate and Between the transporting bodies, the "vibration machine continues to operate", the noise between the shivering becomes large, or the vibration plate and the transporting body. Therefore, the present invention is intended to solve the above-mentioned problem. Achieve - vibrating machine. Rotation of clothing and high durability (means for solving problems) In view of these facts, the present invention, the following matters. As a result of the drilling and research of the electric power (four) shaft, it was found that the outer peripheral side was extended in the radial direction - the deflection deformation of the member from the center side of the base toward the piezoelectric driving body was made = the actual vibrational drive and the elasticity The member is vibrated in the direction of the line to be traversed, so that the pressure is a "fixed surface area which is defined by the connection 1345547 between the vibration absorbing mechanism and the vibration disk and which is fixed to the above-mentioned base and extends in the radial direction. Accordingly, since it will extend in the radial direction The fixing surface area is abutted and fixed to the base, and the mounting fixing member can be attached to the base with a high fixing strength, and the inner peripheral portion of the piezoelectric driving body is fixed at the inner peripheral side end portion of the mounting fixing member. The inner peripheral portion of the piezoelectric actuator is brought close to the center of the vibrating plate. The vibrating transport device of the present invention is characterized in that: the rotary vibrator of any one of the above: A spiral conveying path fixed to the above-mentioned vibration plate and extending in the tangential direction. (Effect of the Invention) According to the present invention, it is possible to realize the high-speed transportation requirement of Wei in recent years. [Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. [Rotary Vibrating Machine] J 1 is a rotating vibration machine of the present invention. FIG. 2 is a schematic plan view showing a state in which the vibrating plate of the rotary vibrating machine is removed, and FIG. 3 is a 砉+ Μ line cut _ 丨 system:::::::((4)(4) moving plate 12, The support ^2__ has: a base 11; a disk-shaped vibration base 11 and a vibration disk table 11; and a vibration absorbing mechanism 13 disposed in the tangential direction, that is, the rotation 12' while rotating the vibration machine 10 The axis 10x (also the axis of the vibrating disk 12 099100517 9) vibrates in the direction of the rotation. The vibration absorbing mechanism 13 is in the example of the figure, around the axis 10x, and now (in the example of the figure, three) The plurality of oscillating mechanisms 13 are disposed at an angular interval around the axis l〇x. Further, the base 11 is placed on the stage 10a via the vibration-proof member (10) such as rubber or spring. The oscillating mechanism 13 as a whole is The axis 10x is centered and has a shape extending in the radial direction. The vibration absorbing mechanism 13 is provided with: The piezoelectric actuator 14 in the radial direction extends toward the outer peripheral side in the radial direction: and a plate-shaped elastic member (plate bomb! is connected and fixed to the piezoelectric actuator 14. The inner circumference of the piezoelectric actuator f 14: via The fixing member 16 is fixed to the upper surface Ua of the base 11. The T-mounting member 16 has a fixing portion 16s extending from the radial direction (four) side toward the outer peripheral side, and the bottom surface of the fixing portion (6) abuts against the base " In the upper 2 Ua shape, the inner peripheral end portion 16a of the base member 11 is fixed to the inner peripheral end portion 16a of the base member 11 by the appropriate fixing means such as the screw test 17, and protrudes laterally from the inner peripheral portion of the fixed region 16s. The mounting solid (four) member 16 has an l-shaped flat inner peripheral end portion 16a fixed to the inner peripheral portion of the piezoelectric driving body, and the mounting member 16 is mounted as shown in the figure. Here, the abutting fixing surface of the inner peripheral end portion and the inner peripheral portion is a surface that faces the tangential direction orthogonal to the radial direction. The piezoelectric actuator body is made of an elastic metal plate such as a _himplate::: an electric component, which is generally used in a bimorph type in which the driving element is placed on the surface of the elastic metal plate, or In the case of the single-sided 099100517 1345547, the intermediate curved portion 15c is maintained in the half-turn direction and then bent in the tangential direction side (clockwise in FIG. 2) in the same manner as the inner peripheral side connecting portion 15a. On the opposite side of the tangential direction (counterclockwise in Fig. 2), the s-shaped shape is extended again in the radial direction. Since the inner peripheral side connecting portion 15a and the outer peripheral side connecting portion 15b both extend in the radial direction, the driving force between the piezoelectric actuator 14 and the vibrating plate 12 is transmitted in the tangential direction, and the piezoelectric driving body 14 can be efficiently driven. The driving force is transmitted to the vibration disk 12.
此處’彈性構件15不受限於上述彎曲形狀，若為例如L 狀、U狀、V狀、曲柄狀等藉彎曲形狀之變化以可進行半徑 方向之伸縮的態樣’則亦可具有任何之彎曲形狀。該等情況 下，内周侧連接部15a與外周侧連接冑15b肖亦可不朝半徑 方向延伸。 t 由上述壓電驅動體14與彈性構件15所構成之加振機構 !3’係在平面上呈朝树方向的姿勢，於相對於水平方向具 有傾斜角θ(參照圖4)之傾斜姿勢被安農。卿，壓電驅動 體14與彈性構件15之板面為朝向切線方向斜上方之姿勢。 上述傾斜角Θ係使勘#12之振動方向s相對於水平切線 方向而朝向斜上方’透過該振動方向s，可將後述搬送體上 之零件朝振動方向S之切線方向斜上方方向進行搬送。傾斜 角<9通;ϋ為5〜2G度之朗内，可根據所要求之搬送特性而 適當設定。 圖5為上述加振機構13與安農固定構件狀俯視圖。在 099100517 12 基台11上，由厭 m 塗電驅動體14和彈性構件15所構成之加振 t亦可3不及女裝固定構件16並行(較佳為平行，但嚴格而 可不平仃)地均沿半徑方向&延伸。在加振機構1 裝固定構件16 + pg 比 之間，透過安裝固定構件16之内周端部i6a 的突出量而設有間隔。 ，電驅動體14之外周部14b、與彈性構件15之内周側連 °M5a’於切線方向T重疊之狀態被固定。因此，彈性構 之内周側連接部15a被配置於朝切線方向T之圖示逆 時針偏移自從壓電轉體M沿半徑方向R延伸之延長線 l4y的位置處。另外，圖示例中，延長線14y為通過軸線1〇χ 而沿半徑方向延伸之直線。另—方面，彈性構件15之外周 側連接部15b透過上述中間f曲部15e，㈣配置於較上述 内周側連接部15a更朝切線方向τ之圖示順時針偏移之位置 處、即被配置於朝壓電驅動體14侧偏移的位置處。結果， 圖示例中，外周侧連接部15b在壓電驅動體14之上述延長 線14y上朝半徑方向r延伸。 如此，壓電驅動體14之外周部14b與彈性構件15之内周 側連接部15a於切線方向T重疊之狀態被固定，會致使切線 方向τ之位置偏移，但因可透過彈性構件15之中間彎曲部 15c的彎曲而加以修正，因此可避免外周側連接部相對 於壓電驅動體14之延長線14y大幅偏離的情況，圖示例令， 外周側連接部15b被配置於廷長線14y上。因此，加振機構 099100517 13 1345547 13整體會朝半徑方向尺正確延伸，因此可將振動盤㈣切 線方向τ有效率地進行驅動。 圖6⑷係彈性構件15之俯視圖，圖_系彈性構件15之 側視圖。此處，上述内周側連接部…構成為平板狀，立中 形成有螺栓插通用貫通孔15t。此外，上述外周側連接部15b 亦構成為平板狀，其中亦形財螺栓_用貫通孔15u。内 周侧連接部15a與外周側連接部15b均構成朝寬度方向（圖 不上下方向）延長之帶狀。另外，圖示例中，對應於壓電驅 動體Η之外周部14b寬度、與振動盤12之被連接部… 之上下寬度，内周侧連接部15a構成為較外周側連接部… 更寬廣。 中間彎曲部…，如上所述財朝切線方㈣曲 當就寬度方向觀看，寬度方向二側（圖示上下二側）外緣 心以分別形成為凹曲線狀（凹圓弧狀），由此其構成為相 對内周側連接部15a與外周侧連接部说任—者均二為相 而且’因料凹曲線狀外緣15d、以，雜構件Η之乍寬: 方向剛性率（剪切彈性觀)分佈，構成為在料方向= f小’伴隨朝内周侧連接部…及外周側連接部15b而逐漸 邊大。 如上述剛性率之半徑方向分佈，可有效地避免彈 15於上述内周側連接部…與中間彎曲部l5e之邊= 例如抵接於在與壓電驅動體14間之連接固定部中所使 099100517 14 用間隔件（墊圈）之端緣的部分）、或上述外周侧連接部15b 與中間彎曲部15c之邊界線15bc(例如抵接於在與振動盤12 間之連接固定部中所使用間隔件（墊圈）之端緣的部分）集中 愛到從壓電驅動體14及振動盤12所承受扭轉方向之應力承 受。此處，因固定朝半徑方向延伸之加振機構13的基台^ 之重心係被配置於下方、而加振機構π所驅動振動盤12 之重心則被配置於上方，故於此構成上必然會發生上述扭轉 方向之應力。 亦即，例如在彈性構件15之寬度在半徑方向保持—定之 情況下，當承受上述扭轉方向之應力後，應力集中於上述邊 界線15ac或15bc處，而有該等邊界線之寬度方向端部發生 龜裂或磨損等之損傷情況。但是，本實施形態中，因為中間 彎曲部15c為寬度隨離邊界線心或心朝半徑方向之= 間位置而變窄之低剛性率構成，因此上述_方向應力 形量，隨著離開邊界線15ae或心而增加。因此，由 由彈㈣件15在半㈣向上整體之變形而承接該扭轉方向 的應力，因此不易發生因應力集中所造成損傷等之不 ^又，因為彈性構件15之外緣W、l5e形成為凹曲線^ 因此更加提升上述扭轉方向應力沿外緣之分散性。、’ 另外，中間彎曲部l5c之中 述凹曲線狀外緣15d、15e^ ^轉方向的剛性會因上 述中間彎” 15始 觸性之降低可由上 間Μ杨朝切線方向之彎曲形狀而受抑制。因此， 099100517 ^^547 本實施形態亦具有在抑㈣性構件15之切線方向剛性降低 之情況下可達到上述凹曲線狀之外緣形狀衍生效果的優點。 本實施形態中，如上述，彈性構件15朝切線方向彎曲而 易於在半徑方向伸縮，因此可吸收加振機構13之振動態樣 非為軸線ΙΟχ 4中心的往復轉動運動致使在加振機構Η與 振動盤12之間產生的半徑方向應力。 亦即，加振機構13外周部之振動態樣若為以軸線10χ為 中心之往復轉動運動，則應該不會產生上述應力，但就實際 問題而言’將加振機構13之内周端配置於軸線ι〇χ上在物 理上極為困難’同時即便可將該内周端配置於軸線10χ上， 實際上’上述振動態樣會由壓電驅動體14發生撓曲振動而 獲得’因此多數之情況下，該振動態樣之中心點會趨向於壓 電驅動體之半徑方向財間位置處。因此，總而言之，彈性 構件15之外周繼接部15b的振動祕半徑，較振動盤12 之被連接部i2a與軸線1〇χ之距離還小，因此隨彈性構件 15之切線方向振幅越大，加振機構13與振動盤η之間所 產生的半徑方向應力亦會變大。 上述應力會使施加至壓電驅動Μ 14时徑方向應力負载 增加，而成為越電驅動體14破損之原因，同時^會使耐 久性降低U造絲域12受應力而變形，^如後 述支撐固定搬送體的振動盤12之支撐面12s產生變形。該 支撐面12s之變形會使搬送體產生應變，同時使搬送體與振 099100517 16 iJ45547 動盤12之間出現間隙，導致振動效率降低，更會增大二者 抵接部分之噪音。 本實施形態中，藉由對上述彈性構件15賦予彎曲形狀， 可減輕上述半徑方向的應力，因此可減輕施加至壓電驅動體 M的半徑方向之應力負載及振動盤12之變形。因此，可防 止壓電驅動體14遭破損，提升耐久性，使振動盤12輕量化， 防止噪音，減低搬送體之應變，並提升從振動盤至搬送體之 騫振動傳遞效率等。 其次，參照圖7與圖8，說明本發明振動式搬送裝置之實 知开>態。圖7為表示本發明振動式搬送裝置一實施例之概略 側視圖，圖8為同裝置之概略俯視圖。振動式搬送裝置4 為所謂碗型零件給料器，其被配置於支撐台3上，該支撐台 3經由多處介設有盤簧等之防振構件2而支撐在設置台i •上。支撐台3上設置有上述旋轉振動機10，該旋轉振動機 ίο之上述振動盤12上固定有碗型搬送體42。在搬送體42 之研缽狀内部，形成有：底部42a，收容零件；及搬送路(軌 道)42b’從該底部42a以螺旋狀逐漸朝向上方。該搬送路4沘 ·.-最終到達搬送體42之外周上部，構成以其前端部42c交接 - 零件至分開配置在支撐台3上的其他振動式搬送裝置5之搬 送路52a。 上述其他振動式搬送裝置5為所謂線性型零件給料器，其 具備有：加振機構51，設置在支撐台3上；及搬送體52， 099100517 17Here, the 'elastic member 15' is not limited to the above-described curved shape, and may be any shape such as an L-shaped, U-shaped, V-shaped, or crank-shaped shape that can be stretched in the radial direction by a change in the curved shape. The curved shape. In these cases, the inner peripheral side connecting portion 15a and the outer peripheral side connecting port 15b may not extend in the radial direction. t The vibration absorbing mechanism !3' composed of the piezoelectric actuator 14 and the elastic member 15 is in a tree-like posture on a plane, and is inclined at an inclination angle θ (see FIG. 4) with respect to the horizontal direction. Annong. The plate surface of the piezoelectric actuator 14 and the elastic member 15 is inclined upward in the tangential direction. The inclination angle Θ is such that the vibration direction s of the survey #12 is obliquely upward with respect to the horizontal tangential direction. The vibration direction s is transmitted, and the components on the transport body described later can be conveyed obliquely upward in the tangential direction of the vibration direction S. The inclination angle <9 passage; ϋ is 5 to 2G degrees, and can be appropriately set according to the required conveyance characteristics. Fig. 5 is a plan view showing the above-described vibration mechanism 13 and Annon fixing member. On the 099100517 12 base 11, the vibration t composed of the anatomically-coated electric drive body 14 and the elastic member 15 may be 3 in parallel with the women's fixing member 16 (preferably parallel, but strict and uneven) Both extend along the radial direction & A gap is provided between the ratio of the inner peripheral end portion i6a of the attachment fixing member 16 between the ratio of the attachment member 16 + pg of the vibration absorbing mechanism 1 . The outer peripheral portion 14b of the electric actuator 14 is fixed in a state in which the inner circumferential side of the elastic member 15 is overlapped with the tangential direction T. Therefore, the inner peripheral side connecting portion 15a of the elastic structure is disposed in a position counterclockwise offset from the direction of the tangential direction T from the extension line l4y of the piezoelectric swivel M extending in the radial direction R. Further, in the illustrated example, the extension line 14y is a straight line extending in the radial direction through the axis 1〇χ. On the other hand, the outer peripheral side connecting portion 15b of the elastic member 15 passes through the intermediate f-curved portion 15e, and (d) is disposed at a position shifted clockwise from the inner peripheral side connecting portion 15a toward the tangential direction τ, that is, It is disposed at a position offset toward the piezoelectric actuator 14 side. As a result, in the illustrated example, the outer peripheral side connecting portion 15b extends in the radial direction r on the extension line 14y of the piezoelectric actuator 14. In this manner, the outer peripheral portion 14b of the piezoelectric actuator 14 is fixed in a state in which the inner peripheral side connecting portion 15a of the elastic member 15 overlaps in the tangential direction T, and the position of the tangential direction τ is shifted, but the permeable member 15 is permeable. Since the intermediate curved portion 15c is bent and corrected, the outer peripheral side connecting portion can be prevented from largely deviating from the extension line 14y of the piezoelectric actuator 14, and the outer peripheral side connecting portion 15b is disposed on the long line 14y. . Therefore, the vibration mechanism 099100517 13 1345547 13 as a whole extends correctly toward the radius direction, so that the vibration plate (four) tangential direction τ can be efficiently driven. Fig. 6 (4) is a plan view of the elastic member 15, which is a side view of the elastic member 15. Here, the inner circumferential side connecting portion is formed in a flat plate shape, and a bolt insertion universal through hole 15t is formed in the center. Further, the outer peripheral side connecting portion 15b is also formed in a flat plate shape, and the through hole 15u is also used for the shape of the fuel bolt. Both the inner peripheral side connecting portion 15a and the outer peripheral side connecting portion 15b are formed in a strip shape extending in the width direction (the vertical direction is not shown). Further, in the illustrated example, the inner peripheral side connecting portion 15a is configured to be wider than the outer peripheral side connecting portion, in accordance with the width of the outer peripheral portion 14b of the piezoelectric actuator and the connected portion of the vibrating plate 12. In the middle curved portion, as described above, the tangential line (four) of the fiscal direction is viewed in the width direction, and the outer edges of the two sides in the width direction (the upper and lower sides of the figure) are respectively formed into a concave curved shape (concave arc shape), thereby The configuration is such that the inner peripheral side connecting portion 15a and the outer peripheral side connecting portion are both the same phase and the 'concave concave curved outer edge 15d, the width of the miscellaneous member :: the direction rigidity ratio (shear elasticity) The distribution is configured such that the material direction = f is small, and the side is gradually increased toward the inner peripheral side connecting portion ... and the outer peripheral side connecting portion 15b. The radial direction distribution of the rigidity ratio can effectively prevent the elastic member 15 from being in the inner peripheral side connecting portion ... and the side of the intermediate curved portion 15e = for example, abutting in the connecting fixing portion with the piezoelectric driving body 14 099100517 14 a portion of the edge of the spacer (washer) or a boundary line 15bc between the outer peripheral side connecting portion 15b and the intermediate curved portion 15c (for example, abutting the interval used in the connecting fixing portion with the vibrating plate 12) The portion of the end edge of the member (gasket) concentrates on the stress receiving from the piezoelectric actuator 14 and the vibrating plate 12 in the torsional direction. Here, since the center of gravity of the base of the damper mechanism 13 that is fixed in the radial direction is disposed below, and the center of gravity of the oscillating disc 12 driven by the oscillating mechanism π is disposed above, the configuration is inevitable. The above-mentioned stress in the torsional direction occurs. That is, for example, in the case where the width of the elastic member 15 is maintained in the radial direction, when the stress in the above-mentioned torsional direction is received, the stress concentrates on the boundary line 15ac or 15bc, and the end portion in the width direction of the boundary line Damage caused by cracks or abrasions. However, in the present embodiment, since the intermediate curved portion 15c is configured to have a low rigidity ratio in which the width becomes narrower depending on the position between the boundary line center and the core in the radial direction, the above-described _directional stress shape amount follows the boundary line. 15ae or heart increases. Therefore, the stress in the torsional direction is received by the elastic deformation of the elastic member (four) member 15 in the upper half (four) direction, so that damage due to stress concentration or the like is less likely to occur, because the outer edges W, l5e of the elastic member 15 are formed as The concave curve ^ thus further enhances the dispersion of the above-mentioned torsional stress along the outer edge. In addition, the rigidity of the concave curved outer edge 15d, 15e^ in the intermediate curved portion 15c may be reduced by the curved shape of the upper Μ Yang toward the tangential direction due to the lowering of the initial bending Therefore, in the present embodiment, the concave shape-like outer edge shape deriving effect can be obtained when the rigidity of the (four) member 15 is reduced in the tangential direction. In the present embodiment, as described above, The elastic member 15 is bent in the tangential direction and is easy to expand and contract in the radial direction, so that the vibrational motion of the absorbing vibration mechanism 13 is not the radius of the axis ΙΟχ 4, and the radius generated between the vibration mechanism Η and the vibration disk 12 is generated. The directional stress. That is, if the vibration dynamics of the outer peripheral portion of the oscillating mechanism 13 is a reciprocating rotational motion centered on the axis 10 ,, the above stress should not be generated, but in terms of practical problems, the inside of the damper mechanism 13 will be It is physically difficult to arrange the circumferential end on the axis ι〇χ, and even if the inner peripheral end can be placed on the axis 10χ, actually the above-mentioned vibrational dynamic sample is driven by the piezoelectric 14 Deflection vibration occurs to obtain 'therefore, in many cases, the center point of the vibrational dynamic sample tends to be at the radial direction of the piezoelectric actuator. Therefore, in summary, the outer peripheral portion 15b of the elastic member 15 The vibration radius is smaller than the distance between the connected portion i2a of the vibrating plate 12 and the axis 1〇χ, so that the amplitude of the tangential direction of the elastic member 15 is larger, and the radial direction between the vibration absorbing mechanism 13 and the vibration disk η is generated. The stress is also increased. The above stress causes an increase in the radial stress load applied to the piezoelectric driving crucible 14 and becomes a cause of breakage of the electric drive body 14, and at the same time, the durability is lowered, and the U filament region 12 is stressed. Deformation, such as deformation of the support surface 12s of the vibrating plate 12 supporting the fixed transport body, which will be described later. The deformation of the support surface 12s causes strain on the transport body, and a gap occurs between the transport body and the vibrating body 099100517 16 iJ45547. The vibration efficiency is lowered, and the noise of the abutting portion is further increased. In the embodiment, by applying a curved shape to the elastic member 15, the radial stress can be reduced. Therefore, the stress load applied to the piezoelectric actuator M in the radial direction and the deformation of the vibration disk 12 can be reduced. Therefore, the piezoelectric actuator 14 can be prevented from being damaged, the durability can be improved, and the vibration disk 12 can be made lighter and noise can be prevented. The strain of the conveyance body is reduced, and the vibration transmission efficiency from the vibrating plate to the conveyance body is improved. Next, a state of the vibrating conveyance device of the present invention will be described with reference to Figs. 7 and 8. Fig. 7 is a view showing the present invention. A schematic side view of an embodiment of the vibrating transport apparatus according to the present invention, and Fig. 8 is a schematic plan view of the same apparatus. The vibrating transport apparatus 4 is a so-called bowl type feeder which is disposed on the support table 3, and the support table 3 passes through The vibration-proof member 2 such as a coil spring is provided to be supported on the installation table i. The support table 3 is provided with the above-described rotary vibrating machine 10, and the bowl-shaped transfer body 42 is fixed to the vibrating plate 12 of the rotary vibrating machine. Inside the mortar-like shape of the conveying body 42, a bottom portion 42a is formed to accommodate the components, and a conveying path (track) 42b' is gradually turned upward from the bottom portion 42a in a spiral shape. The transport path 4沘.. finally reaches the outer peripheral portion of the transport body 42, and the transport path 52a of the other vibrating transport device 5 that is placed on the support table 3 by the front end portion 42c is disposed.
