Description

VIBRATORY PARTS-FEEDING APPARATUS}

TECHNICAL FIELD The present invention relates to a vibrating component conveying apparatus, and more particularly, to a structure of an apparatus for conveying components along a spiral conveyance path by rotational vibration around an axis.

In general, as a parts conveying apparatus called a parts feeder, a bowl-type conveying vibrating body in which a spiral conveying path is formed on an inner circumferential surface thereof is prepared, and a large amount is provided in the inner bottom of the conveying vibrating body. The apparatus of the type | mold which conveys, while storing a part of and conveys a part along the said spiral conveyance path by giving rotation conveyance vibration about an axis to a conveyance vibrating body is known.

In this kind of component conveying apparatus, as shown in FIG. 10, the bowl-type conveying vibrating body 2 is mounted on the vibrational plate 1a of the rotary vibrator 1 which gives rotational vibration about an axis line. Although it is necessary to fix, in the case of the small component conveying apparatus for conveying a large quantity of fine components, the through-hole 2a is centered in the center of the bottom part of the conveying vibrating body 2 comprised as an integrated molded article as a 1st fixed structure. Is vertically formed, and the bolt 3 is passed through the through hole 2a to be screwed to the vibrating plate 1a of the rotary vibrator 1 so that the conveying vibrating body 2 is driven by the bolt 3. The central part of was made to fasten and fix in the axial direction with respect to the vibration board 1a.

Moreover, in the case of the large component conveying apparatus for conveying a comparatively large component, the conveyance vibrating body which forms a conveyance path by joining a spiral strip | belt-shaped metal plate inside the cylindrical outer peripheral wall formed of sheet metal is used in many cases. When using such a conveying vibrating body, as a second fixing method, the bottom portion of the outer circumferential wall of the conveying vibrating body is brought into direct contact with the outer circumferential portion of the vibrating plate of the rotating vibrator from the outside, and the fastening plate is formed from the outer side of the bottom of the outer circumferential wall. the conveying vibrating body is mounted on the vibrating plate by placing the fastening plate at a plurality of locations along the outer periphery by touching the (tightened plate) and fastening the fastening plate in the radial direction with respect to the vibrating plate by bolts, thereby sandwiching the bottom part. It fixed to it (for example, refer patent document 1 below).

Moreover, as a 3rd fixing method of the conveying vibrating body and a diaphragm in the components conveying apparatus provided with such a large conveying vibrating body, an annular leg part is provided in the bottom part of a conveying vibrating body, and this leg part is attached to a vibrating plate. There is also a structure in which the bolt is screwed into the attachment rib through the leg part and fixed in a radial direction directly in a state where the fitting rib is fitted to the outside of the installation rib (for example) , See patent document 2 below).

In addition, an attachment block disposed on the outer peripheral portion of the bottom portion of the conveying vibrating body mounted on the vibration plate is provided with an outer peripheral expansion portion formed by causing the outer peripheral portion of the vibration plate to protrude outward, and a through hole is formed obliquely in the vertical direction to the outer peripheral expansion portion. A fourth fixing method is also known in which the mounting block is secured by pressing the bottom portion of the conveying vibrating body firmly in the axial direction to clamp the outer circumferential expansion portion by fastening the bolt by a bolt screwed through the through hole (for example, , See patent document 3 below).

[Patent Document 1] Japanese Patent Application Laid-Open No. 3-138803 [Patent Document 2] JP 37-3612 [Patent Document 3] Japanese Patent Application Laid-Open No. 1-134614 [Patent Document 4] Japanese Patent No. 4280291

However, in the first fixing method, only the center of the bottom of the conveying vibrating body is fastened to the vibrating plate in the axial direction by bolts, so that the outer periphery of the conveying vibrating body is not directly fixed to the outer periphery of the vibrating plate. Therefore, the deformation of the conveying vibrating body causes unnecessary vibrations on the outer circumference, which hinders the efficient conveying form and the alignment posture of the parts, and the fixing force to the stress in the rotational direction depends only on the frictional force at the center part. When the vibration plate of the rotary vibrator and the conveying vibrator fixed thereto become rotational displacement around the axis line, the vibration state between the vibrating plate and the contact surface of the conveying vibrator causes noise or scratches on the contact surface, resulting in a change in the fixed state. There is a problem. In particular, when the amplitude of the rotational vibration is increased by increasing the driving voltage for the piezoelectric element, the noise is aggravated, and the components on the conveying vibrating body are jumped to prevent efficient conveyance. There was also a problem that adversely affects the alignment posture of.

Since the above problems are caused by fixing the vibration plate and the conveying vibrating body only in the vicinity of the axis of rotational vibration by the fastening force in the axial direction, even if the fastening force is increased, it is not a fundamental solution. Moreover, when the rigidity of a conveying vibrating body is raised in order to reduce deformation, another problem arises that it becomes inevitable to make the conveying vibrating body lightweight. The weight reduction of this conveying vibrating body is a very important problem when trying to increase the rotational frequency in order to respond to the recent request for improving the conveying speed. In particular, in the case of a small component conveying apparatus, rotational vibrators using a piezoelectric vibrating body have been increasing in recent years. When the weight of the conveying vibrating body is large, the cost is increased to increase the rigidity of the piezoelectric vibrating body, or the piezoelectric vibrating body is used. The problem that the durability falls is likely to occur.

On the other hand, in the second fixing method and the third fixing method, the above-described various problems do not occur because the outer peripheral bottom of the conveying vibrating body is fixed to the vibrating plate, but the conveying vibrating body is radially relative to the vibrating plate. Direct fixation in the axial direction is insufficient in the axial fixation force and fixation accuracy, and rotational vibration cannot be transmitted to the conveying vibrating body with sufficient accuracy, so that fine electronic parts cannot be conveyed efficiently and with high accuracy. There is this. In addition, since the conveying vibrating body employing such a fixing method is often formed by joining a metal plate by welding or the like, when the vibration frequency is increased to increase the conveying speed of the parts, unnecessary vibrations such as the metal plates of the respective parts vibrate in the thickness direction, respectively. Since this tends to occur easily, there is a problem that the structure of the conveying vibrating body itself causes problems in miniaturization of the conveying parts and the increase in conveying speed. In addition, since the conveying vibrating body and the diaphragm need to be directly secured by bolts, the conveying vibrating body and the diaphragm need to be formed so as to be formed of integrally molded articles (including processed integral parts) having a high-precision shape for conveying fine electronic components. The conveying vibrating body has a problem that it is difficult to secure the machining operation and rigidity.

In the fourth fixing method, since the conveying vibrating body is fastened and fixed to the vibrating plate in the axial direction, it is difficult to avoid the positional displacement in the horizontal direction along the plane orthogonal to the axis, in particular, as described above. In addition, there is a problem that transmission of high-precision rotational vibration is difficult. Moreover, since it is necessary to provide the outer periphery expansion part which protrudes largely on the outer periphery of a vibration board, the load weight with respect to rotational vibration becomes large and it is difficult to compact, and also the attachment part provided with the surface which protrudes to the outer periphery in the bottom part of a conveyance vibrating body is formed. Since it is necessary to carry out, in the conveyance vibrating body formed by sheet metal processing by welding etc., the conveying vibrating body formed from the integrally molded article (including the processed integral product) with the high precision shape for conveying a minute electronic component, There is a problem that it is difficult to secure the machining operation and rigidity.

Further, in the second to fourth fixing directions, the conveying vibrating body is directly fixed to the vibration plate in the radial direction or the axial direction by the screw coupling structure by bolts, or is sandwiched by a fastening plate or an attachment block. In the case where the fastening is fixed at a plurality of places, since the conveying vibrating body cannot be removed or attached from the vibrating plate unless the bolt is removed or fastened at all the places, there is a problem that the detachable work is complicated.

Therefore, the present invention solves the above problems, and its problem is that the rotating vibration generated by the rotary vibrator can be efficiently and accurately transmitted to the conveying vibrating body, whereby the fine conveying parts can be precisely aligned and conveyed. An oscillating component conveying apparatus which can carry out high speed conveyance easily is also implemented.

In view of such circumstances, the vibrating component conveying apparatus of the present invention is a rotating vibrator for vibrating a vibrating plate about an axis, and a conveying vibrating body including a spiral conveying path which is mounted on the vibrating plate and provided around the axis. In the vibrating component conveying apparatus provided, the outer mounting surface arrange | positioned closely on the surface of the said vibration board is formed in the outer side of the bottom part of the said conveying vibrating body, The said conveying vibrating body is outer side of the said outer mounting surface. The outer circumferential portion of the vibration plate is fixed by a clamp structure at a plurality of places around the axis and the axis, the clamp structure includes a clamp member attached to an outer circumferential portion of one of the vibration plate and the conveying vibrating body; It is formed in the outer peripheral part of the other of the vibration board and the said conveyance vibrating body, and couple | bonded with the said clamp member in the axial direction And a slanted engagement surface, the inclined engagement surface inclined with respect to the axial direction to the opposite side to the one outer peripheral portion and at least two of the plurality of clamp structures in a surface orthogonal to the axis. The conveyance vibrating body is fixed on the vibration plate by being set in different directions, and the clamp face provided on the clamp member is pressed against the inclined engagement surface closely.

According to the present invention, the clamp face of the clamp member is coupled to the inclined engagement surface, and the outer circumference portion of the vibration plate and the outer circumference portion of the conveyance vibrating body placed on the surface closely are fixed by the clamp structure, whereby Since the direct rotational vibration is provided, deformation and distortion between the conveying paths of the conveying vibrating bodies are reduced, and as a result, the rotating vibrations generated in the vibrating plate can be efficiently and accurately transmitted to the parts. In addition, the carrier vibration body can be fixed in the axial direction and the horizontal direction by the inclination of the inclined engagement surface inclined with respect to the axial direction and set in different directions between the plurality of clamp structures in the axial direction and the horizontal direction. Compared with the conventional fixing method in which the fixing action in either direction is dependent on the frictional force, the deflection of the fixing force applied to both methods is lowered, so that rotational vibration can be transmitted from the diaphragm to the conveying vibrating body efficiently and with high accuracy. . Therefore, fine conveying parts can be conveyed in high accuracy and aligned, and the speed of parts conveyance can be improved. In each clamp structure, only the cover structure is pushed in the inclined direction so as to closely close the clamp surface to the inclined engagement surface, and then the plurality of such clamp structures are set up in different directions in the horizontal plane. Since the conveying vibrating body can be fixed to the vibrating plate, it is necessary to detach all the fixing portions in a configuration in which the conveying vibrating body and the vibrating plate are directly fixed or sandwiched in a plurality of fixed portions as in the conventional structure. In comparison, there is also an advantage that the detachable operation can be performed only by operating only some clamp structures except at least one clamp structure.

In one embodiment of the present invention, the inclined engagement surface is configured to face in the radial direction in a plane perpendicular to the axis, and the clamp member is configured to be movable in the radial direction with respect to the one outer peripheral portion. According to this, in the plurality of clamp structures, both the radially inclined engagement surface is formed and the clamp member is configured to be movable in the radial direction, thereby moving the clamp member in the radial direction between the clamp surface and the inclined engagement surface. It is possible to control the close force of or to detach the conveying vibrating body with respect to the vibration plate easily. In particular, the inclined engagement surface is configured to face radially outward in the surface, and the conveying vibrating body is fixed to the vibration plate while the clamp surface is pressed against the inclined guide surface from the radially outer side to the inward side, thereby providing a clamp structure. It is possible to simplify the operation of the device and at the same time facilitate the removal operation. For example, as shown in an embodiment to be described later, the inclined engagement surface is configured to face radially outward in a plane perpendicular to the axis line, and the bolt member is screwed into a screw hole formed in the outer peripheral portion of the clamp member. And clamping the clamp face against the inclined engagement surface by fastening the inner side in the radial direction with respect to the outer peripheral portion, and the conveying vibrating body can be fixed to the vibrating plate. By simply moving the member in the radial direction, it becomes possible to form or release the intimate state of all the inclined engagement surfaces and the clamp surfaces to execute the detachment operation.

In another form of this invention, the said clamp structure is provided in three places about the said axis line, and the said one clamp member in the said clamp structure of at least 1 place of three said clamp structures is with respect to the said one outer peripheral part. It is attached so as to be movable in the radial direction, and it is comprised so that the said conveyance vibrating body may be detachable from the said vibration board, without moving the two other clamp members by moving the said one clamp member to the said radial direction. In this case, in the other two clamp structures, the clamp member may be configured to be movable in the radial direction, or may not be.

In still another aspect of the present invention, the clamp member has an engaging claw that regulates movement toward the other outer peripheral portion by engaging with the outer peripheral portion of the one side. According to this, since the movement to the said outer peripheral part of the said clamp member is restrict | limited, position displacement of the clamp member in the axial direction of the clamp member in a state in which the carrier vibrating body is fixed to the vibration plate by engaging the clamp surface with the inclined engagement surface. since a can be surely prevented, it is possible to stabilize the fixed state of the transfer oscillator. This coupling claw can be comprised so that it may couple | bond with the edge part on the opposite side to the other outer peripheral part in one outer peripheral part, for example.

In another form of this invention, the said inclined engagement surface is comprised so that it may face radially outward in the surface orthogonal to the said axis line, and the said clamp member is urged radially inward with respect to the said one outer peripheral part. According to this, the attachment structure to one outer peripheral part of a clamp member can be comprised easily, and the attachment work | work and removal operation of a clamp member can be made easy.

In this case, a bolt for fastening the clamp member is provided, a fixing hole through which the bolt is inserted and passed is installed in the clamp member, and a screw hole in which the bolt is screwed is installed in the outer peripheral portion of the clamp member. desirable. According to this, a clamp member can be reliably fastened although it is a simple and inexpensive structure. In this case, the bolt further has a male screw portion, a cylindrical positioning portion formed at a position different from the male screw portion in an axial direction, and the screw hole includes a female screw portion for screwing into the female screw portion, and the positioning. It is preferable to have a guide part which guides a part. According to this, since the position of the bolt with respect to the one outer peripheral part different from a screwing structure can be set precisely by the fitting of a positioning part and a guide part, the clamp member is moved by the bolt precisely positioned with respect to one outer peripheral part. Since the position of the clamping member can be precisely coupled to the inclined engagement surface, the positional displacement of the clamp member can be reliably prevented while the conveying vibrating body is fixed to the oscillating plate, so that the fixed state of the conveying vibrating body is stabilized. You can.

According to this invention, the outer peripheral part of a conveyance vibrating body can be fixed more reliably to both the axial direction and the horizontal direction with respect to the outer peripheral part of a vibration board in the state which the deflection to either of them was reduced. Therefore, since rotational vibration can be transmitted efficiently and with high precision, the outstanding effect of being able to carry out fine conveying components with high precision by alignment, and improving conveyance speed can be acquired.

EMBODIMENT OF THE INVENTION Next, embodiment of this invention is described in detail with reference to an accompanying drawing. First, the component conveyance apparatus of 1st Embodiment which concerns on this invention is demonstrated with reference to FIGS.

The component conveying apparatus 10 of 1st Embodiment is equipped with the rotating vibrator 11 and the conveying vibrating body 12 fixed on this rotating vibrator 11. The rotary vibrator 11 includes a mounting plate 13 and a dustproof material 14 formed of a rubber (for example, a vibration ring, etc.) or a spring (for example, a coil spring, etc.) for vibration prevention on the mounting plate 13. It has a diaphragm 16 (top plate) disposed above the base supported by the base. An internal structure (not shown in FIG. 1) 17 disposed inside the base 15 is interposed between the base 15 and the vibration plate 16, and this internal structure 17 is interposed. The diaphragm 16 is horizontally supported on the base 15 via.

As shown in FIG.7 and FIG.8, the internal structure 17 is arrange | positioned along the axis line 22y extended radially centering on the axis line 10x of the component conveyance apparatus 10, and is plate-shaped. Iii) a plurality of excitation mechanisms 20 having a series connection structure between the piezoelectric drive body 22 and the leaf spring 23. In the example of illustration, the excitation mechanism 2 is provided in three sets at equal angle intervals around the axis line 10x. The excitation mechanism 20 is connected between the base 15 and the vibration disk 16 to impart rotational vibration around the axis 10x to the vibration disk 16 with respect to the base 15. . On the inner surface 15 a (surface facing upward at an inclination angle θ described later) of the base 15, the bottom surface of the fixing portion 21s of the fixing member 21 extending in parallel with the radial axis 22y extends. The inner end of the piezoelectric drive body 22 is connected to the inner end 21a which is fixed in an intimate state and protrudes in the rotational direction around the axis 10x from the end of the fixing portion 21s of the fixing member 21. It is fixed.

The piezoelectric drive body 22 is not particularly limited, but has a structure (unimorph or bimorph structure) in which a piezoelectric layer is laminated on one or both surfaces of an elastic plate. The piezoelectric drive body 22 extends radially over the axis line 22y as a whole, and rotates at an inclination angle θ (see FIG. 9) with respect to a vertical plane (a surface including both the axis line 10x and the axis line 22y). It is provided so that it may face the inclined upper side of one side (counterclockwise direction in FIG. 7). Although this inclination-angle (theta) is suitably set according to the conveyance form of the component on the conveyance path in the conveyance vibrating body 12, it is about 5-15 degrees normally. The leaf spring 23 is also basically connected to the outer end of the piezoelectric drive body 22 so as to extend in the same radial direction as the piezoelectric drive body 22 and to face upward inclined at the same inclination angle θ with respect to the vertical plane.

However, in the illustrated example, the leaf spring 23 is moved radially from the inner side to the outer side so that the outer end of the leaf spring 23 is disposed on the radial line 22y extending in the radial direction of the piezoelectric drive body 22. It is curved in the other direction of rotation (clockwise in FIG. 7). Thereby, since the axis line 22y of the piezoelectric drive body 22 is arrange | positioned in the radial direction which connects the center point which passes through the axis line 10x, and the outer end part of the leaf spring 23, it is by the static pressure application path | route which is not shown in figure. Due to the flexural deformation of the piezoelectric drive body 22 generated, the motion trajectory when the outer end of the leaf spring 23 imparts rotational vibration to the vibration plate 12 is centered on the axis 10x. Since it can be made into the form which approximates a circular arc, it becomes possible to make the vibration board 16 rotate and oscillate efficiently and with high precision. Moreover, the leaf | plate spring 23 has the shape in which the both edges of the width direction were formed in concave curve shape, and the intermediate part was distorted. This concentrates the stress in the torsional direction caused by the load on the leaf spring 23 by the weight of the vibration plate 16 or the conveying vibrating body 12 in the width direction, and the leaf spring 23 This is to prevent cracks from occurring at the connecting portions at both ends of the longitudinal direction.

The outer end of the vibrating mechanism 20 (that is, the outer end of the leaf spring 23) is connected to the connecting portion 16a of the vibration disk 16 provided to protrude downward in the outer peripheral portion of the vibration disk 12. The connection is fixed. In the example of illustration, this connecting part 16a is provided in three places corresponding to the said excitation mechanism 20 at equal angle intervals. In addition, a concave portion 15b is formed in the outer circumferential portion of the base 15 in correspondence with the connecting portion 16a, and the connecting portion 16a is configured to protrude into the concave portion 15b. It is comprised so that 16 may not contact except in the part which interposes the internal structure 17 (vibration mechanism 20).

The diaphragm 16 is circular in planar view, and its surface (upper surface) 16s is formed flat. The conveying vibrating body 12 is mounted on the surface 16s. The conveying vibrating body 12 is an integrally formed article (including a processed integral article) formed of aluminum or an alloy thereof, stainless steel, or the like, which is configured as a bowl as a whole. The conveying vibrating body 12 has an inner bottom part 12a whose inner surface 12s is formed in a conical shape, and an outer circumferential part 12b that is annularly formed on the radially outer side of the inner bottom part 12a. The inner surface 12t of) consists of an inclined surface inclined in an inverted cone shape. On this inner surface 12t, the conveyance path 12w (refer FIG. 2) formed so that it may rise gradually to the outer side spirally from the outer peripheral part (lowest part) of the inner surface 12s of the said inner bottom part 12a is formed. . Although the detailed structure, such as the cross-sectional shape of this conveyance path 12w, abbreviate | omits illustration, the groove | channel of the cross-sectional L-shape is formed in the inner surface 12t, for example. The center hole 12g is formed in the center of the vibration conveyance body 12, and it adjusts so that the weight balance may be obtained in the rotation direction centering on this center hole 12g. The outer circumferential portion (lowermost portion) of the inner surface 12s is used as a component storage, and the components stored therein are subjected to rotational vibration to the conveying vibrating body 12 and gradually upwards on the conveying path 12w. It is made to be conveyed. Moreover, in this embodiment, although the spiral conveyance path 12w is formed on the inner surface 12t, it is also possible to form a spiral conveyance path on an outer peripheral surface by providing a component storage part in an outer peripheral bottom.

The inner bottom part 12a is thin in that the side (bottom face side) opposite to the inner surface 12a is formed in concave shape in order to reduce the weight of the conveyance vibrating body 12. The weight reduction of the conveying vibrating body 12 is important for raising the frequency of the rotational vibration of the conveying vibrating body 12 to improve the conveying speed. This can efficiently vibrate the driving vibrator 12 by the rotary vibrator 11 near the resonance point, but the weight of the conveying vibrator 12 is required to increase the resonance frequency at this time. Because. On the other hand, by securing the thickness of the outer peripheral part 12b and increasing rigidity, it is possible to convey components on the conveyance path 12w in an orderly and efficient manner. The rigidity of the outer circumferential portion 12b is very important in preventing the parts from jumping when conveying fine parts. If the conveyance path 12w is also precisely rotated and vibrated in accordance with the rotational vibration transmitted from the rotary vibrator 11, the parts are conveyed smoothly and efficiently while maintaining posture without jumping, but conveyed with low rigidity of the outer peripheral portion 12b. If the furnace 12w vibrates in a different form from the above-mentioned rotational vibration or if the rotational vibration is absorbed before reaching the conveying path 12w, the parts will not be jumped or efficient parts conveying will be possible.

The outer periphery 12b of the conveying vibrating body 12 has a cross section in which the bottom side is thick in the radial direction as a whole and the top side is thin in the radial direction by the cross-sectional shape of the inner surface 12t. In addition, the bottom portion 12c of the outer circumferential portion 12b is provided at a position projecting downward, and is provided with a flat bottom surface 12d (12d above), which is placed closely on the surface 16s of the outer circumferential portion of the vibration plate 16. Corresponds to the mounting surface). This bottom surface 12d is comprised in the annular strip | belt shape centering on the axis line 10x, and is comprised so that it may be in close contact with the surface 16s of the outer peripheral part of the diaphragm 16. As shown in FIG. In this embodiment, the bottom surface 12d provided in the bottom part 12c is formed only in the outer peripheral part 12b, and the bottom surface shape of the inner bottom part 12a is concave in the area | region located inside the bottom surface 12d. It is comprised so that it may not contact the diaphragm 16 by being comprised. For this reason, since the rotary vibration of the vibration board 16 is transmitted to the outer peripheral part 12b of the conveying vibrating body 12 only in the bottom surface 12d provided in the outer periphery, the conveyance path formed in the outer peripheral part 12b efficiently ( 12w). In addition, in the example of illustration, since the outer edge of the bottom part 12c of the conveyance vibrating body 12 protrudes outward rather than the outer peripheral part of the vibration board 16, the part of the outer side of the flat bottom surface 12d is a vibration board 16. As shown in FIG. Although it is not in contact with the surface 16s of), as described later, it is preferable that the entire flat bottom surface 12d is in close contact with the surface 16s. However, in this example, even if the dimensional relationship between the vibration disk 16 and the conveying vibrating body 12 changes somewhat, the outer peripheral part of both can be fixed without difficulty by using the clamp member 18 of the shape suitable for this dimensional relationship. It can be seen that.

As shown in FIG. 4, the recessed groove 12e is formed in the outer edge of the bottom part 12c of the conveyance vibrating body 12, ie, the outer peripheral edge of a bottom part. This concave groove 12e includes an end having an inclined engagement surface 12f on the lower side (vibration disk 16). The recessed groove 12e and the inclined engagement surface 12f are formed annularly around the axis 10x in the example of illustration. Although the attachment angle position with respect to the vibration board 16 of the conveyance vibrating body 12 is made free by this, if it is not necessary, it may be provided only in the angle position corresponding to the clamp structure mentioned later. In this case, the concave groove 12e and the inclined engagement surface 12f are formed to extend in an arc shape about the axis 10x in plan view when viewed in the rotational direction around the axis 10x.

The inclined engagement surface 12f is configured to face radially outward and inclined upward. That is, the inclined engagement surface 12f is inclined with respect to the direction of the axis 10x to face the opposite side to the vibration plate 16, and in the plane (horizontal plane) perpendicular to the axis 10x, between the three clamp structures. Consists of faces facing each other in different directions. In the illustrated example, each inclined engagement surface 12f in the three clamp structures faces radially outward in the horizontal plane, but the radially outward at the angular position of each clamp structure is a different direction in the horizontal plane, As a result, the directions in the horizontal plane of each of the inclined engagement surfaces 12f are all different between the clamp structures. In general, the inclination direction in the horizontal plane may be different from at least two inclined engagement surfaces 12f of the plurality of clamp structures.

The inclination angle Φ based on 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 provided in the clamping claw 18b of the clamping member 18 which the conveyance vibrating body 12 is fixed to the vibration board 16, ie, the inclined engagement surface 12f is mentioned later. It is the inclination angle in the state close to the clamp surface 18d, and therefore 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. Even when the inclination angle Φ deviates from the angle range, a certain effect can be obtained as compared with the conventional structure, but the direction of the fixing force is in the axial direction (the direction in which the conveying vibrating body 12 is pressed against the vibrating plate 16). Since it deflects in either of the radial directions, the fixed force in the horizontal direction given by the direction difference between the plurality of clamp structures, and the axial direction (the conveying vibrating body 12) applied in the respective clamp structures are placed on the vibration disk 16. The tightening torque of the clamp member tends to be excessive to either side of the fixing force of the pressing direction) or to avoid this.

At this time, the rotational vibration imparted to the conveying vibrating body 12 from the vibration plate 16 has an upward direction of inclination toward the side which rotates about the axis 10x in order to produce a component conveyance force. For this reason, when the fixing force of one of a horizontal direction and an axial direction is insufficient, a displacement of a vibration board and a conveying vibrating body will become easy in this direction, and transfer efficiency to a conveying vibrating body of vibration displacement will fall, and conveyance efficiency will deteriorate, The displacement causes unnecessary vibration, which makes the component easy to jump. In particular, when the vibration frequency is increased to increase the conveying speed, it is caused by the frictional force in the direction orthogonal to each of the fixing directions used in the conventional structure (the axial direction in the fastening part in the radial direction and the horizontal direction in the fastening part in the axial direction). Since the fixing action to be made is hardly expected, the transmission loss of vibration becomes large, high-speed conveyance becomes difficult, and unnecessary vibration arises, and a component posture becomes unstable.

On the outer circumferential surface of the diaphragm 16, a screw hole 16b having an axis extending horizontally in the radial direction is formed, and the clamp member 18 is formed by the bolt 19 screwed into the screw hole 16b. It is fastened and fixed on the outer circumferential surface of (16). These screw holes 16b, the clamp member 18, and the bolt 19 together with the concave groove 12e (end) constitute the clamp structure of the present invention. This clamp structure is provided in plural places around the axis 10x. In particular, in order to reliably fix in a horizontal direction, it is preferable to provide a clamp structure in three or more places. In the example of illustration, clamp structures are provided in three places at equal angle intervals around the axis 10x.

The clamp member 18 has a fixing hole 18a having a short mounting hole structure through which the bolt 19 is inserted, and the fixing hole 18a has a radial axis line and has a clamp member 18. Penetrating) In the middle of the fixing hole 18a, a stepped portion facing radially outward is provided, and the head of the bolt 19 is coupled to the stepped portion so that the bolt 19 is screwed into the diaphragm 16. When screwed and fastened to 16b), the clamp surface 18d of the clamp member 18 is pressed against the inclined engagement surface 12f.

The clamp claw 18b which protrudes radially inward is provided in the upper part (part of the conveyance vibrating body 12 side) of the clamp member 18, and this clamp claw 18b has the inclined engagement of the said recessed groove 12e. An end having the clamp face 18d described above in close contact with the face 12f is formed. The clamp claw 18b and the clamp surface 18d are in the planar view when viewed in the rotational direction around the axis 10x so as to match the concave groove 12e and the inclined engagement surface 12f described above. It is formed in inverted arc shape centering on).

In the lower part of the clamp member 18 (part on the opposite side to the conveying vibrating body 12), an engaging clow 18c protruding radially inward is provided, and the engaging claw 18c is a vibrating plate 12. Is coupled to each corner between the outer circumferential surface and the bottom surface, and regulates the position of the conveying vibrating body 12 side of the clamp member 18. That is, the coupling claw 18c is coupled to the vibration plate 16 in the state where the clamp member 18 is pressed toward the vibration plate 16 by the bolt 19 to the vibration plate 16 of the clamp member 18. The movement toward the conveying vibrating body 12 side (upper city shown) is regulated. In addition, in this embodiment, the clamp structure is divided into two parts of the angle between the angle positions (shown in the rotational direction in the rotational direction in the example of illustration) which avoided the connection part 16a which protrudes downward in the vibration board 16. FIG. In the ship's position). As a result, the engaging claw 18c can be engaged with the lower edge portion of the outer circumferential surface of the vibration plate 16 without being disturbed by the connecting portion 16a.

With the above configuration, the clamp member 81 is attached to the movable member in a radial direction with respect to the outer circumferential portion of the vibration plate 16 by the bolt 19. As a result, the clamp member 18 can be easily engaged with or removed from the bottom circumferential edge of the conveying vibrating body 12, and the fastening holding force with respect to the conveying vibrating body 12 can be adjusted. For example, the bolt 19 is screwed into the screw hole 16b by inserting and passing the bolt 19 through the fixing hole 18a of the clamp member 18. 18 can be fastened, the clamp claw 18b of the clamp member 18 can be engaged with the recessed groove 12e, and the clamp surface 18d can be brought into close contact with the inclined engagement surface 12f. In this case, the gap between the outer circumferential portion of the vibration plate 16 and the clamp member 18 is such that the clamping claw 18b is sufficiently pressurized by the recessed groove 12e so that the conveying vibrating body 12 has a fixed force inside the radial direction. It is set so that it may be reliably positioned at the same time, and at the same time, may receive a fixing force at the lower side and be surely pressurized by the vibration board 12. In this state, it is preferable that the inner circumferential surface of the clamp member 18 is in contact with the outer circumferential surface of the vibration plate 12 as shown in the figure, in order to increase the attachment stability of the clamp structure.

In this embodiment, as shown to FIG. 2A and FIG. 2B, the clamp structures formed in three places all have the same structure (structure with rotational symmetry). And these clamp structures are provided in equiangular (120 degree) space | interval about the axis line 10x. In each clamp structure, the clamp member 18 is configured to be movable in the radial direction with respect to the vibration plate 16 by rotating the bolt 19. However, only one of the clamp structures loosens the bolt 19 to clamp the member. By moving the 18 in the radial direction, the conveying vibrating body 12 can be removed from the vibrating plate 16 without operating the bolt 19 in the other two clamp structures. If the screwing depth of the bolt 19 to the diaphragm 16 is set in advance in the two clamp structures, the remaining two clamp members 18 in the state where the bolt 19 is loosened in the other clamp structure. The conveying vibrating body 12 is placed on the vibrating plate 12 in a state of being fitted to the clamp claw 18b of the present invention, and then the conveying vibrating body 12 is simply tightened by the bolt 19 of this clamp structure. Can be fixed on the vibrating plate 16. This is because each clamp structure merely holds the inclined engagement surface 12f in the inclined direction on the clamp surface 18d, and is not fixed using a direct fastening fixing structure or a clamped fixing structure as in the conventional structure. This is because setting and releasing of the fixed state of all clamp structures can be performed only by operation of some clamp structures. In general, the detachable operation can be performed without moving the clamp member of the at least one clamp structure. However, it is easy to configure so that attachment / detachment operation | work can be carried out even without operating two or more clamp structures only by operation of one clamp structure like this embodiment. In addition, in this case, since there is no need to operate a bolt in the clamp structure other than the clamp structure which has a clamp member which requires a movement operation (screw coupling operation), the clamp member 18 is attached to the vibration board 16. FIG. You may attach with the structure which can not move with respect to (the structure which can be attached only to a fixed position).

In this embodiment described above, the bottom part 12c provided in the outer peripheral part 12b of the conveyance vibrating body 12 is raised on the surface 16s of the outer peripheral part of the vibration board 16, and is formed in the bottom part 12c. The clamp claw 18b of the clamp member 18 couples to the recessed groove 12e, and the inclined engagement surface 12f and the clamp surface 18d are in close contact, so that the conveying vibrating body 12 is placed on the vibrating plate 16. It is fixed. Therefore, since the clamping force is applied not only in the axial (vertical) direction to the oscillating plate 16 but also toward the radially inward direction, the clamping force 12 is applied in the three clamp structures. Fixing force in the direction is given in different directions. For this reason, since the conveyance vibrating body 12 is fixed to both a horizontal direction and an axial direction, compared with the conventional structure which depended on frictional force at least one of the horizontal direction and the axial direction, the vibration board 16 Rotational vibration can be transmitted to the conveying vibrating body 12 efficiently and with high accuracy, and unnecessary vibration can be prevented from occurring in the conveying vibrating body 12, and noise can also be reduced.

In more detail, in the component conveyance apparatus 1 of this embodiment, the rotary vibrator 11 generate | occur | produces the rotary vibration of the direction inclined with respect to the horizontal plane (surface orthogonal to the axis 10x), Although rotational vibration is provided to the conveying vibrating body 12, when fixing a conveying vibrating body with respect to a vibration board with an axial direction in the conventional fixing method by the outer periphery, the vibration of an axial line (vertical) direction Although components can be efficiently transferred, there is a possibility that displacement in the horizontal direction can occur between them, which makes efficient conveyance difficult, thereby making it impossible to increase the conveyance speed and possibly causing jumping or noise of components. In addition, when the conveying vibrating body is fixed to the oscillating plate by the fastening in the radial direction, there is a possibility that displacement may occur in the axial direction. Therefore, it is also difficult to efficiently transmit the vibrations, which makes it difficult to increase the conveying speed. There is also a risk of noise.

In contrast, in the clamp structure of the present embodiment, the conveying vibrating body 12 is moved to the vibration disk 16 by applying the clamping force in the direction inclined with respect to the axial direction while being set in different directions in the horizontal plane in the plurality of clamp structures. Since it is possible to reliably fix both the horizontal direction and the axial direction with respect to), rotational vibration can be reliably transmitted from the conveying plate 16 to the conveying vibrating body 12 with high accuracy. In the case of conveyance, an efficient conveyance form can be realized, the conveyance speed can be increased, the jumping of parts can be prevented, and the noise can also be reduced. In addition, as described above, in each clamp structure, the clamp surface 18d is merely pressed and covered in an inclined direction with respect to the direction of the axis line 10x so that the clamp surface 18d is in close contact with the inclined engagement surface 12f. Since the conveying vibrating body 12 is fixed to the diaphragm 16 by providing the several clamp structure which has the inclined engagement surface 12f set to the direction, it is fixed directly in the radial direction or the axial direction by the screw coupling structure by a bolt. Compared with the conventional method to do this, there also exists an advantage that attachment / detachment operation becomes easy. In particular, the clamp member 18 has a structure in which the clamping stress is applied to the conveying vibrating body 12 radially inwardly, thereby simplifying the clamp structure and making the attaching and detaching work easier. Moreover, since the fixing action of an axial direction and a horizontal direction can be provided in the same location, the effect that unnecessary vibration which arose in the conveyance vibrating body 12 can be suppressed is also acquired. In addition, the use of the clamp member 18 increases the degree of freedom of the fixed structure portions of the conveying vibrating body 12 and the diaphragm 16, and furthermore, by using the inclined engagement surface 12f, it is possible to secure the fastening in the axial line 10x direction. Since the rigidity of the vicinity of a surface becomes easier than the case of forming the horizontal surface to be used, there exists an advantage that it becomes possible to simplify the fixed part structure, ensure rigidity, and reduce processing cost.

On the other hand, when the component conveying apparatus 10 of this embodiment is compared with the fixing method shown in FIG. 10, the advantageous effect can be acquired at the following points. In the fixing method shown in FIG. 10, since only the center part of the conveyance vibrating body 2 is being fixed by the bolt 3, the deformation | transformation of the conveyance vibrating body 2 is deformed by the rotational vibration received from the vibration board 1a. As a result, an unnecessary vibration mode occurs in the outer circumference of the conveying vibrating body 2, whereby uncomfortable parts cannot be efficiently conveyed, or the parts are inconvenient such as jumping during conveyance or noise. Moreover, since the conveyance vibrating body 2 is fixed only by the frictional force in the center in the rotation direction with respect to the vibration board 1a, when a vibration frequency becomes high, the vibration component of a rotation direction will be easy to be absorbed by a fixed part, and transmission of vibration will be carried out. The efficiency is significantly lowered. On the other hand, in this embodiment, the outer mounting surface (bottom surface 12d) mounted on the surface 16s of the vibration board 16 on the outer side of the bottom part of the conveyance vibrating body 12, and the vibration board 16 is provided. Since the outer circumferential portion of the diaphragm is fixed to the outer circumferential portion 12b of the conveying vibrating body 12 by the clamp structure, the outer circumferential portion 12b having the bottom portion 12c in which rotational vibrations come into contact with it from the outer circumferential portion of the vibrating plate 16. Since the vibration path of the carrier path 12w is close to the vibration mode of the vibration board 16, the vibration path of the carrier path 12w is transmitted in the axial direction and in the axial direction, and the vibration transmission can be carried out efficiently and with high accuracy. have. Therefore, the parts can be conveyed at high speed and stably, the conveying force imparted to the parts can be prevented, or the parts can be prevented from jumping on the conveying path 12w, and noise can be prevented. . Moreover, the outer peripheral part of the vibration board 16 is fixed to the outer peripheral part 12b of the conveying vibrating body 12, and is fixed to the outer peripheral part 12b of the conveying vibrating body 12, and the inner peripheral part of the conveying vibrating body 12 is carried out. This makes it possible to reduce the speed of the vehicle, making the high speed half speed even easier.

Moreover, in this embodiment, the coupling claw 18b is provided in the clamp member 18, and this coupling claw 18b couple | bonds with the edge part on the opposite side to the surface 16s of the diaphragm 16, and clamp member Since the movement of 18 is restricted to the conveying vibrating body 12 side with respect to the vibration board 16, the clamp state by the clamp member 18 can be realized reliably and stably (with good reproducibility).

In addition, in this embodiment, in the rotary vibrator 11, three excitation mechanisms 2 are provided at equal angle intervals in the rotation direction, and these excitation mechanisms 20 are provided at three places provided at equal angle intervals in the rotation direction. Since the vibration disk 16 is driven to generate rotational vibration, and the vibration disk 16 and the conveying vibrating body 12 are fixed by the clamp structure at three positions provided at equal angle intervals in the rotation direction, each clamp structure The stress accompanying the rotational vibration applied to can be equally burdened, and the transmission state of the rotational vibration can be stabilized.

Next, 2nd Embodiment which concerns on this invention is described with reference to FIG. In this embodiment, only the clamp structure shown in FIG. 5 and the structure of its vicinity are different from the said 1st Embodiment, and since the other structure is the same as 1st Embodiment, description is abbreviate | omitted about the same part.

In the present embodiment, the clamp member 18 'is attached by screwing the bolt 19' to the screw hole 16b formed in the outer circumferential portion of the vibration plate 16, and at the same time, the clamp claw of the clamp member 18 ' 18b ') is similar to the first embodiment in that the outer circumferential portion 12b of the conveying vibrating body 12 is fixed, but the structure of the clamp member 18' itself is different. The clamping claw 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.

Moreover, in this embodiment, the guide hole part 16b 'provided with the cylindrical inner surface in which the female thread is not provided in the opening side which is a position different from an axial direction from the part in which the female thread of the said screw hole 16b is formed ( Corresponds to the guide part). On the other hand, the bolt 19 'is not provided with a male screw on the side of the head 19b' which is a position different in the axial direction from the portion where the male screw 19a 'corresponding to the female screw of the screw hole 16b is provided. 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 16b ', and the bolt 19' and the vibration plate 16 are required. It is made to position with positioning precision. The positioning shaft portion 19c 'is inserted into the fixing hole 18a provided in the clamp member 18' and passed through, but at this time, the bolt 19 'and the clamp member 18' are positioned by the positioning shaft portion 19c. Is positioned to the required positioning precision. Therefore, the clamp member 18 'is protected and held in the axial direction with the required positional accuracy with respect to the vibration board 16 via the said positioning shaft part 19c. As a result, the denture accuracy in the axial direction with respect to the concave groove 12e of the clamp claw 18b 'can be easily ensured, so that the conveying vibrating body 12 can be reliably and stably (with good reproducibility). It can be fixed to (16).

In addition, in this embodiment, since the front surface of the bottom surface 12d of the conveying vibrating body 12 is in contact with the surface 16s of the vibrating plate 16, the conveying vibrating body 12 is further on the conveying board 16. It is raised in a stable state. Corresponding to this structure, the protrusion amount of the clamp claw 18b 'of the clamp member 18' to the radially inner side is increased, and the clamp claw 18b 'is configured to reach the concave groove 12e. However, as illustrated by the dotted line in the figure, the outer peripheral edge of the bottom of the conveying vibrating body 12 may protrude to the outer peripheral side than the vibration plate 16 and may be configured to engage with the corresponding clamp claw. none.

Next, a third embodiment according to the present invention will be described with reference to FIG. 6. Also in this embodiment, since only the clamp structure shown in FIG. 6 and the structure of its vicinity are different from the said 1st Embodiment, and the other structure is the same as 1st Embodiment, description is abbreviate | omitted about the same part.

In this embodiment, the bottom peripheral edge is protruded on the outer peripheral side than the bottom surface 12d mounted on the vibration board 16 'of the conveying vibrating body 12, and the recessed groove 12e is formed here. . And the clamp member 18 provided with the clamp claw 18b "in the position separated from the vibration board 16 'to the outer peripheral side according to the shape of the bottom outer peripheral edge in which the recessed groove 12e of the conveyance vibrating body 12 was formed. ") Is installing. The clamp member is formed in accordance with the shapes of the vibrating plate 16 'and the conveying vibrating body 12 combined in this way, and various combinations can be easily coped with. In addition, the clamping member 18 "of this embodiment is provided with the engaging claw 18c" like the 1st Embodiment, and this engaging claw 18c "is engaged with the lower edge part of the vibration board 16 ', By providing this engaging claw 18c ", even if the outer periphery of the conveyance vibrating body 12 protrudes outward from the outer peripheral surface of the vibration board 16, a stable clamp state can be implement | achieved.

By the way, in the said embodiment, as shown in FIG. 2B, although the inclination engagement surface 12f and the clamp surface 18d are formed along the rotation direction R about the axis 10x in the horizontal plane, FIG. 2C or FIG. 2D As shown in the figure, the inclined engagement surface 12f and the clamping surface 18d may be formed in such a manner as to intersect the rotational direction R. As shown in FIG. Here, in the configuration shown in Fig. 2C, the inclined engagement surface 12f and the clamp surface 18d in the horizontal plane are flat even though they face the axis 10x and intersect with the arc-shaped rotational direction R. Yes. 2D is an example in which the inclined engagement surface 12f and the clamp surface 18d in the horizontal plane face a direction different from the axis 10x and intersect the rotational direction R (in the illustrated example, in the horizontal plane). It consists of a flat surface, but may be an arcuate surface). In these cases, in the clamp structure of at least one of a plurality of clamp structures, the carrier vibrating body is configured such that the inclined engagement surface 12f and the clamp surface 18d in the horizontal plane intersect with respect to the rotation direction R. Since (12) is fixed by the closeness of the surface which faces at least obliquely also to the rotation direction R with respect to the vibration board 16, since the fixing force with respect to the rotation direction R can be heightened further, it is possible to further raise the effect of this invention. It is possible. Further, in this case, it is more preferable to configure so that the crossing state with respect to the rotational angle R other than the crossing angle is different between the at least two clamp structures. Although the above description shows an example in which the inclined engagement surface 12f faces radially outward in the horizontal plane, and the clamping face 18d faces inward in the radial direction in the horizontal plane, on the contrary, the inclined engagement surface 12f is in the radial direction. It is also possible to configure so that it faces inward and the clamp surface 18d faces radially outward.

In addition, the present inventors have driven the conventional component conveying apparatus shown in Fig. 10 and the component conveying apparatus 10 of the first embodiment at the same vibration frequency, so that the component conveying apparatus 10 has a higher conveying speed as a whole. It was confirmed that the conveyance posture is also maintained. In particular, when the driving voltage for the piezoelectric drive body 22 is increased to increase the amplitude of the rotational vibration, in the conventional component conveying device, the noise increases, and the components on the conveying path become difficult to align by jumping and do not move efficiently. Although the problem of the said thing arises, it turned out that the components conveying apparatus 10 generate | occur | produces noise, hardly jumps a component, and conveyance speed becomes higher. The two parts conveying apparatuses compared are small devices for conveying minute parts (for example, LED chips, etc.) of about 0.2 to 1.5 mm in width, length, and height, respectively. Moreover, compared with the conventional apparatus, the components conveying apparatus 10 can raise conveyance speed to about 1.5-2 times, and the favorable conveyance speed was obtained even if the drive voltage was lower than the conventional apparatus.

In addition, the component conveyance apparatus of this invention is not limited only to the example of illustration demonstrated above, Of course, various changes can be added within the range which does not deviate from the summary of this invention. For example, in each said embodiment, the clamp member 18 is attached to the outer peripheral part of the vibration board 16 with the bolt 19 etc., and the clamp member 18 is attached to the outer peripheral bottom part of the conveyance vibrating body 12, for example. Although the inclined engagement surface 12f which the clamp surface 18d engages is formed, in contrast to this, while attaching a clamp member with a bolt etc. to the outer peripheral bottom of the conveyance vibrating body 12, You may provide the inclined engagement surface which a clamp surface engages in an outer peripheral part. Moreover, in the said embodiment, although the inclination engagement surface 12f all faces radially outward in a horizontal plane, the inclination engagement surface 12f should just be comprised in a different direction between at least two clamp members of a some clamp structure, Therefore, the individual inclined engagement surfaces 12f may face radially inward in the horizontal plane, or may face toward other directions.
