Description

  The present invention relates to a vibratory transfer device and a rotary vibrator, and more particularly, to an internal structure of a rotary vibration mechanism suitable when a plate-like piezoelectric vibrator is used as a vibrator.

  In general, various vibratory transfer devices are used to transfer electronic components, etc., but in recent years, this type of vibratory transfer device has been required to have a high supply speed and high supply accuracy, and has a high speed and high performance. There is an urgent need for it. In general, it is required to convey parts at a high speed with their conveying postures perfectly aligned. To that end, it is necessary to convey parts efficiently and stably by vibration. In order to realize such an efficient and highly stable conveyance mode, in addition to increasing the frequency of vibration, vibration (vibration) of the vibration table formed by the component conveyance path is reduced and the vibration direction is reduced. Must be set with high accuracy.

  As a conventional vibratory transfer device, a bowl-type transfer device having a spiral component transfer path is known. In this bowl-type transfer device, an electromagnet-type or piezoelectric-type shaker, and this shaker A vibration mechanism that is connected to an amplifying leaf spring that amplifies vibration generated by the vibration is connected between the base and the vibration table (conveyance body), and a plurality of vibration mechanisms are installed in the same posture around the axis. Thus, a rotary vibrator configured to generate a turning vibration is used. In particular, in recent years, piezoelectric vibrators are often used as the vibrators with the progress of miniaturization and high frequency.

Conventionally, as the above-described rotary vibrator, a vibration vibrator, a leaf spring, or the like is attached between the base and the vibration base in a posture inclined in the longitudinal direction. In response to the demand for higher frequency, a rotary vibrator of a type in which a vibrating body and a leaf spring are installed so as to extend in a horizontal direction or a radial direction has been proposed. The following Patent Documents 1 to 6 all relate to a bowl-type conveyance device, and can be configured to have a low height or to improve installation stability by providing a vibration mechanism extending in the horizontal direction. A rotary vibrator configured as described above is disclosed. For example, a vibration support mechanism in which a support column is erected at the center of the base, and a piezoelectric vibrator (with a piezoelectric material attached to the surface of the elastic plate) and a leaf spring are connected in series to the support column. There has been proposed a structure in which an inner end is attached, the excitation mechanism is horizontally extended radially outward, and the outer end is connected to the bottom of a vibration table or a transport body (bowl).
Japanese Utility Model Publication No. 57-46517 Japanese Patent Publication No. 60-45084 JP-A-62-201709 JP-A-62-201710 JP-A-1-104508 Japanese Patent Laid-Open No. 9-110133

  By the way, as described above, in the bowl-type vibratory transfer device, in order to meet the demands for reducing the size of transfer parts and increasing the transfer speed, it is necessary to optimize the vibration mode as well as increase the vibration frequency. When the vibration is increased in frequency, the vibration direction is likely to vary, and the conveyance component is miniaturized, so that the variation in the conveyance direction of the conveyance component due to the variation in the vibration direction is likely to occur. Therefore, in order to improve the conveyance efficiency, it is necessary to reduce the variation in the vibration direction at the same time as increasing the vibration frequency.

  The variation in the vibration direction occurs when an unnecessary vibration mode, for example, an unnecessary vibration mode other than the vibration mode having the original frequency and vibration direction (torsional vibration mode, longitudinal vibration mode, etc.) occurs. Such an unnecessary vibration mode is likely to occur due to insufficient rigidity of each part. In particular, in order to efficiently vibrate a transport body such as a bowl, it is necessary to increase the inertia weight of the base and efficiently propagate the vibration generated by the vibration mechanism to the vibration base and the transport body. The mounting portion of the base with respect to the vibration mechanism needs to have sufficient rigidity, which is effective in reducing the above unnecessary mode. However, in the above-mentioned conventional rotary vibrator, a strut is provided in the center of the base and the inner end of the vibration mechanism is attached to the strut, so that the rigidity of the strut can be sufficiently increased. However, if the rigidity of the strut part is sufficiently increased, it is necessary to increase the outer diameter of the support part or increase the mounting area. is there.

  Therefore, the present invention solves the above-described problems, and the problem is that, in a rotary vibrator or a vibratory transfer device including the same, it is possible to reduce the variation in the vibration direction while increasing the frequency of vibration and to improve the transfer efficiency. An object of the present invention is to provide a structure capable of increasing the size and reducing the size of a rotary vibrator.

  In view of such circumstances, the vibratory transfer device of the present invention includes a base, a transport body provided with an annular or spiral component transport path disposed on the base, the base and the transport body. And a vibration mechanism that vibrates the conveyance body in the rotational direction. The vibration mechanism is arranged on the conveyance body side from an inner end connected to the base side. Arranged in a posture extending in a radial direction toward an outer end connected to the base, and is connected to an inner end of the vibration mechanism between the vibration mechanism and the base. A connecting part having a base side connecting portion that extends radially outward in parallel with the mechanism and is connected to the base is interposed.

  According to the present invention, the base-side connecting portion of the connection part extends radially outward and is connected to the base side, so that the excitation mechanism can be connected to the base over a wide radial range via the connection part. Since it is possible to fix to the base, it is possible to securely and firmly attach the vibration mechanism without projecting the support column in the center of the base, and the support column itself is no longer necessary. It becomes possible to arrange the inner end portion of the vibration mechanism close to the axis. Therefore, generation of unnecessary vibration modes can be suppressed to reduce variation in vibration direction, and the outer diameter of the apparatus can be reduced to reduce the size.

  In the present invention, it is preferable that a plurality of vibration mechanisms are respectively installed at a plurality of locations around the axis, and the inner ends of the plurality of vibration mechanisms are directly opposed in the horizontal direction in the vicinity of the axis. According to this, the inner ends of the plurality of vibration mechanisms installed around the axis are directly opposed in the horizontal direction in the vicinity of the axis, so that the inner ends of the vibration mechanism can be brought closer to the axis, The apparatus can be configured compactly as a whole. In addition, since the vibration mode of the vibration mechanism is close to an arc-shaped vibration centered on the axis, the inconsistency of the vibration modes between the plurality of vibration mechanisms can be reduced. It is possible to further suppress the occurrence of variations.

  In the present invention, the connection component has a substantially L-shape in which an excitation-side connection portion connected to the excitation mechanism protrudes and the base-side connection portion extends in a radial direction. It is preferable. According to this, it is possible to securely and firmly fix the inner end portion of the vibration mechanism with the connecting component, and to arrange the inner end portion of the vibration mechanism in the vicinity of the axis, while the connecting component has a narrow angle in the rotation direction. Since it becomes possible to arrange | position within the range, the further size reduction of an apparatus can be achieved.

  In the present invention, the vibration mechanism has a posture in which a plate-shaped vibration body made of a piezoelectric vibration body and an elastic plate connected in series to the vibration body extend in a substantially linear shape in the radial direction. It is preferable that the vibrator is arranged longer in the radial direction than the elastic plate. According to this, the vibration body and the elastic plate connected in series in the vibration mechanism are arranged substantially linearly in the radial direction, so that the conveyance body can be vibrated efficiently in the rotation direction. Become. In addition, since the vibrating body is configured to be longer than the elastic plate in the radial direction, the spring constant of the vibrating mechanism can be increased, so that it is possible to easily achieve high frequency vibrations and variations in the vibration direction. Further reduction can be achieved.

  Next, the rotary vibration machine of the present invention is interposed between the base, the vibration base disposed on the base, and the base and the vibration base, and vibrates the vibration base in the rotation direction. In the rotary vibrator having the vibration mechanism, the vibration mechanism extends in a radial direction from an inner end portion connected to the base side toward an outer end portion connected to the vibration table side. Between the excitation mechanism and the base, connected to the excitation mechanism, and extended radially outward in parallel with the excitation mechanism and connected to the base A connection component having a base side connection portion is interposed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side view of a rotary vibrator used in the vibratory transfer apparatus according to the first embodiment, FIG. 2 is a schematic plan view showing a state in which the shake table of the machine is removed, and FIG. 3 shows a vibration mechanism of the machine. FIG. 4 is a side view (a), a bottom view (b) and a longitudinal sectional view (c) of the shaking table of the aircraft, and FIG. 5 is a plan view showing a state in which components are removed from the base of the aircraft. . As is well known, the vibration type conveying apparatus is formed by attaching a conveying body 112 (see FIG. 6) provided with a helical or circumferential conveying path to the upper portion (vibrating table 15) of the illustrated rotary vibrator 10. Is done.

  As shown in FIG. 1, the rotary vibrator 10 of the present embodiment includes a mounting base 11 and a base 13 mounted on the mounting base 11 via an elastic member 12 such as an anti-vibration rubber and a coil spring. Have. A vibration table 15 is attached and supported on the base 13 via a vibration mechanism 14. Although an elastic support member (a leaf spring or the like) can be attached between the base 13 and the vibration table 15 separately from the vibration mechanism 14, the vibration table 15 is supported only by the vibration mechanism 14 in this embodiment. Has been.

  As shown in FIG. 2, the connection component 16 is attached and fixed to the upper surface of the base 13. The connecting component 16 is preferably made of a material having a higher elastic modulus (Young's modulus) or rigidity than the constituent material of the base 13. In particular, it is effective to use a material having a high rigidity in order to efficiently transmit vibration and suppress unnecessary vibration modes, which will be described later. The inner end portion of the vibration mechanism 14 is attached and fixed to the connection component 16. The vibration mechanism 14 extends in the radial direction about the axis 10x, and its outer end is attached and fixed to the vibration table 15. The vibration mechanism 14 includes a vibration body 14A that is a piezoelectric vibration body in which a piezoelectric body 14A2 is bonded to the outer surface (both outer surfaces in the illustrated example) of an elastic substrate (shim plate) 14A1, and an elastic plate that includes a leaf spring or the like. 14B is connected in series.

  As shown in FIG. 3, the vibration mechanism 14 has a portion on the vibration body 14 </ b> A side connected to the connection component 16, and a portion on the elastic plate 14 </ b> B side connected to the vibration table 15. The elastic substrate 14A1 and the elastic plate 14B of the vibrating body 14A are connected and fixed by a connecting tool 18 through a resin spacer 17 using bolts or the like. Further, between the elastic substrate 14A1 of the vibrating body 14A and the connection component 16, and between the elastic plate 14B and the vibration table 15, the connection tool 18 is connected and fixed using a bolt or the like via the resin spacer 17, respectively. ing. In addition, the connection aspect of each component is not limited to the said aspect, It can fix with various fixing methods, and it is also possible to comprise elastic board 14A1 and elastic board 14B with an integral elastic body. . However, in this embodiment, the resin spacer 17 is inserted in each connection portion, so that the attachment portion of the elastic substrate 14A1 or the elastic plate 14B of the vibrating body 14A is less likely to break due to metal fatigue or the like. is doing.

  The connecting component 16 includes a base side connecting portion 16A extending in the radial direction, and a rotation direction around the axis 10x from the inner end portion of the base side connecting portion 16A (in the illustrated example, counterclockwise when viewed from above, hereinafter The excitation-side connecting portion 16B is provided so as to project in the counterclockwise direction as the forward rotation direction and the clockwise direction as the reverse rotation direction. The base-side connecting portion 16A has a shape extending radially outward from the excitation-side connecting portion 16B side, specifically, a planar shape extending linearly outward in the radial direction. Reference numeral 16 denotes a substantially L-shaped planar shape. Fixing holes 16a (see FIG. 3) are formed in the base side connecting portion 16A at two locations inside and outside in the radial direction, and bolts or the like are inserted into these fixing holes 16a to attach the mounting surface 13a (see FIG. 3). The base-side connecting portion 16 </ b> A is attached and fixed to the base 3 by being screwed into the screw holes 13 e perforated in FIG.

  Further, as shown in FIG. 3, the connection component 16 supports and arranges the vibration mechanism 14 at a position shifted upward from the lower end portion by the gap G so that the vibration mechanism 14 contacts the inner surface of the base 3. Without being arranged, it is arranged with a sufficient interval. A stepped attachment surface 16b is formed on the vibration side connection portion 16B of the connection component 16, and the elastic substrate 14A1 of the vibration body 14A is fitted to the attachment surface 16b (via the resin spacer 17 in the illustrated example). Thus, both the rotational direction and the radial direction are fixed.

  In the vibration mechanism 14, the vibration member 14A is configured to be longer in the radial direction than the elastic plate 14B, and the vibration generated by the vibration member 14A is amplified by the elastic plate 14B and transmitted to the vibration table 15 rather than the conventional structure. Rather, the vibration body 14A generates a required vibration, and the elastic plate 14B serves to remove a slight mismatch between the vibration mechanisms 14 due to the plurality of vibration mechanisms 14 being installed by bending or the like. Plays. That is, in the present embodiment, a plurality of vibration mechanisms are provided along a plurality of installation shafts 10y (three in the illustrated example) that are disposed in the radial direction around the axis 10x (set at equal angular intervals in the illustrated example). 14 is installed, each of the excitation mechanisms 14 has a vibration direction unless the plurality of excitation mechanisms 14 produce an arcuate vibration perfectly aligned around the axis 10x with respect to the vibration table 15. There is a risk that the piezoelectric body may be damaged when a load due to the distortion of the pressure increases. Therefore, in the present embodiment, the elastic plate 14B plays a role of releasing strain.

  However, in the present embodiment, as will be described later, the inner end portion of the vibration mechanism 14 is disposed in the vicinity of the axis 10x. Therefore, in the vibration mechanism 14 that extends substantially linearly in the radial direction, the axis 10x is approximately centered. An arcuate vibration mode is realized. Therefore, even if a plurality of vibration mechanisms 14 are installed around the axis 10x, the inconsistency in the vibration direction between the vibration mechanisms 14 is greatly reduced as compared with the conventional apparatus. Therefore, the length of the elastic plate 14B can be shortened, and thereby various effects can be obtained at the same time, not only making the device compact, but also reducing variations in the vibration direction and facilitating higher frequencies.

  As shown in FIG. 5, the base 13 is provided with a mounting surface 13 a to which the connection component 16 is fixed. This mounting surface 13 a is basically formed on the connection surface of the base-side connection portion 16 </ b> A of the connection component 16. The surface shape is a corresponding surface (flat surface in the illustrated example). The mounting surface 13a is slightly inclined in the reverse rotation direction, and the vibration mechanism 14 connected via the connection component 16 is similarly inclined clockwise, so that the vibration direction of the vibration table 15 is in the forward rotation direction. It is configured to go diagonally upward. The attachment inclination angle of the vibration mechanism 14 (that is, the inclination angle in the vibration direction) is preferably set within a range of 1 to 20 degrees, for example, and particularly set within a range of 3 to 15 degrees. desirable.

  Here, the attachment surface 16b of the connection component 16 and the connection surface of the vibration mechanism 14 in close contact therewith are in a direction orthogonal to the vibration direction of the vibration mechanism 14 or the normal line of the surface of the vibration body 14A or the elastic plate 14B. It is a flat surface. As a result, it is possible to improve the integrity of the connection component 16 and the vibration mechanism 14 with respect to the mechanical influence on the normal vibration mode, so that occurrence of unnecessary vibration modes can be reduced.

  The mounting surface 13a and the inner surface portion on the positive rotation direction side are formed in a concave groove shape as a whole, thereby securing a storage space for storing the excitation mechanism 14 and the connection component 16. This accommodation space forms an opening 13 c on the outer periphery of the base 13. Further, a thick-walled base portion 13b is formed on the mounting surface 13a on the reverse rotation direction side, thereby succeeding in increasing the weight of the base 13 without increasing the outer shape of the apparatus. . Further, a central recess 13d in which the base portion 13b is not formed is provided in the vicinity of the axis 10x of the base 13, and the inner end portion of each excitation mechanism 14 and the connection component 16 are provided in the accommodation space provided by the central recess 13d. The vibration side connection part 16B is arranged.

  As shown in FIG. 4, the vibration table 15 has a disk-shaped upper plate portion 15a and a protruding portion 15b protruding downward from the outer peripheral portion of the upper plate portion 15a. The outer end portion of the mechanism 14 is attached and fixed. The projecting portion 15b is in a state of being accommodated through a sufficient space with respect to a concave groove-shaped accommodation space provided in the opening 13c of the base 13, and the base 13b of the base 13 is Since the outer peripheral portion of the upper plate portion 15a of the vibration table 15 is configured to face the range where the protrusions 15b are not provided, the base 13 and the vibration table 15 are brought into contact with each other at a minimum interval. Oppositely arranged so as not to touch.

  On the bottom surface (surface facing the base 13) of the upper plate portion 15a of the vibration table 15, a wheel-like thick wall having an annular rim portion at the outer peripheral portion through a plurality of spoke portions extending radially from the central hub portion. A portion 15c and a plurality of thin portions 15d formed in a concave shape between the thick portions 15c are provided. Thereby, sufficient rigidity is secured while reducing the weight of the vibration table 15. In addition, the said protrusion part 15b is provided corresponding to the connection part of a spoke part and a rim | limb part. Thereby, the rigidity with respect to the vibration received from the vibration excitation mechanism 14 can be further improved.

  FIG. 6 is a plan view showing a component supply device 100 including a bowl-type vibration conveying device 110 using the rotary vibrator 10. In this component supply device 100, a bowl-type vibration transfer device 110 and a linear-type vibration transfer device 120 are supported on an installation table 101. The vibration-type transfer device 110 includes the rotary vibrator 10 and a bowl-shaped transfer body 112 that is fixedly mounted on the vibration table 15. The transfer body 112 includes an inner bottom 112a. The spiral component conveyance path 112b is formed so as to gradually extend upward. The vibratory transfer device 120 includes a linear vibrator 121 that vibrates in a linear direction, and a transport body 122 fixed on the linear vibrator 121. The transport body 122 includes the component transport path 112b. A linear component conveyance path 122a to be connected is formed.

  A large number of parts (not shown) deposited on the inner bottom 112a of the bowl-shaped transport body 112 gradually move upward along the spiral part transport path 112b, and move to the part transport path 122a at the outlet to linearly move. Go to. In such a component supply apparatus 100, since it is necessary to supply a small part at very high speed, the vibration-type transfer apparatus 110 that is often installed in the uppermost stream requires a large amount of transfer capability. In the present embodiment, by using the rotary vibrator 10, the components on the component conveying path 112a are efficiently conveyed in a vibration mode with high frequency and little direction variation.

  The rotary vibrator 10 and the vibration transfer device 110 of the present embodiment described above have the following operational effects. In general, in this type of rotary vibrator and vibratory conveyance device, it is important to efficiently vibrate the vibration table 15 and / or the conveyance body 112 using the inertia weight of the base 13. It is effective to reduce the weight of the vibration table 15 and / or the conveyance body 112 by increasing the weight of the vibration table 15. However, there is a limit in reducing the weight of the vibration table 15 and / or the conveyance body 112 because it is necessary to ensure rigidity to prevent deformation, and the increase in the weight of the base 13 also increases the height and outer diameter of the apparatus. There is a limit in reducing the size by reducing the size. Therefore, in the present embodiment, by increasing the rigidity of the mounting portion of the base 13 to which the vibration mechanism 14 is mounted, the inertia weight of the base 13 is effectively used and the vibration is efficiently propagated. Optimization has made it possible to reduce the variation in vibration direction and increase the efficiency of conveying parts.

  In other words, in the conventional device, the vibration mechanism is attached to the column portion projecting from the central portion of the base, so that the rigidity of the column itself tends to be insufficient and the moment of inertia in the rotation direction of the base is reduced. Since it cannot be used, the substantial mounting rigidity of the vibration mechanism is low, so that the vibration energy generated by the vibration mechanism is easy to escape to the base side and the vibration cannot be efficiently propagated. Since the vibration part partially generates an unnecessary vibration mode and the variation in the vibration direction increases, the parts cannot be efficiently conveyed.

  On the other hand, in this embodiment, the vibration mechanism 14 is attached to the base 13 via the connection component 16, so that the protruding column part as described above is not necessary, and the base 13 has a high rigidity. The vibration mechanism 14 can be attached to (the flat portion of the inner surface of the base 13), and the vibration mechanism 14 can be fixed to a wide range outside in the radial direction via the connection component 16. This makes it possible to effectively use the inertia weight of the base 13. Accordingly, vibration can be efficiently propagated to the vibration table 15 and / or the carrier 12, and an unnecessary vibration mode is suppressed to optimize the vibration mode, that is, to suppress variation in vibration direction. be able to.

  On the other hand, from another viewpoint, in this embodiment, the support column is not necessary as described above, and the inner ends of the plurality of vibration mechanisms 14 are directly opposed to each other (the support column of the base 13). Since the inner end of the vibration mechanism 14 can be brought close to the axis 10x, the outer diameter of the apparatus can be reduced and the vibration operation of the vibration mechanism 14 can be reduced. When the fulcrum approaches the axis 10x, the vibration mode applied to the vibration table 15 or the conveyance body 112 is close to the circular vibration around the axis 10x, and thereby an ideal vibration mode of the vibration table 15 or the conveyance body 112 is obtained. In particular, since the plurality of vibration mechanisms 14 respectively provide substantially concentric arc vibrations to the vibration table 15 or the conveyance body 112, occurrence of variations in the vibration direction is also suppressed. Of course, since the base 13 can be miniaturized as a reflective effect due to the fact that the inertia weight of the base 13 can be effectively used as described above, the entire apparatus can be miniaturized. Become.

  Further, by interposing a connection component 16 different from the base 13 between the vibration mechanism 14, it is possible to use a material having a high rigidity different from the material of the base 13 in the connection component 16. Therefore, the performance can be improved while suppressing an increase in cost, and the shape of the connection component 16 corresponds to the normal vibration direction, that is, the vibration body 14A of the vibration mechanism 14 or the elastic plate. By adopting a block structure having an inclination posture corresponding to an inclination direction such as 14B, it becomes easy to maintain a normal vibration mode, and an effect of suppressing an unnecessary vibration mode can be enhanced.

  In the present embodiment, the base side connection portion 16A of the connection component 16 is arranged in parallel on the reverse rotation direction side of the vibration mechanism 14, but the present invention is in such an aspect. For example, contrary to the above, the base side connection portion 16 </ b> A may be arranged in parallel on the forward rotation side of the vibration mechanism 14. You may comprise so that the base side connection part 16A may be arrange | positioned in the downward position which overlaps with the mechanism 14 planarly.

  Further, in the above-described embodiment, the vibration mechanism 14 is attached and fixed to the base 13 via the L-shaped connecting part 16, but the present invention is not limited to such an aspect, and as a result, the addition is performed. A portion corresponding to the vibration mechanism 14 and the connection component 16 is configured in a U-shape or a U-shape as a whole, and a base-side connection portion 16 </ b> A extending in the radial direction in parallel with the vibration mechanism 14 exists in the connection component 16. And the base side connection part 16A should just be connected and fixed to the base 13, for example, the structure by which the linear connection component was attached to the L-shaped excitation mechanism may be sufficient. Further, the base-side connecting portion 16A is not limited to a shape extending linearly in the radial direction as shown in the illustrated example, and if extending in the radial direction, a disk shape, a columnar shape, It may be configured in a rectangular block shape.

  Further, in the above-described embodiment, the vibration-type transfer device 110 in which the transfer body 112 is fixed on the vibration table 15 of the rotary vibrator 10 has been described. However, the present invention is not limited to such an aspect. Alternatively, the conveying body 112 may be directly connected to the outer end of the vibration mechanism 14 instead of the vibration table 15.
