  In general, a vibratory bowl feeder includes a bowl having a spiral part conveyance path formed on the inner surface, an upper vibrator to which the bowl is attached, a lower vibrator installed below the upper vibrator, and both vibrators. An elastic member to be connected and a vibration mechanism for applying vibration to both vibrating bodies are provided, and the bowl is vibrated by driving the vibration mechanism to convey the components along the conveyance path. In such a vibratory bowl feeder, as an elastic member for connecting the upper vibrator and the lower vibrator, it is inclined along the horizontal virtual reference line extending radially from the center of rotation of both vibrators and with respect to the vertical plane. There is one that vibrates the bowl in the horizontal rotation direction and the vertical direction by using the leaf springs arranged in this manner (see, for example, Patent Document 1).

  By the way, when the elastic members such as the leaf springs are arranged so as to extend in the horizontal direction as described above, the elastic members of the upper vibrating body and the lower vibrating body along the virtual reference line in order to ensure the rigidity in the vertical direction. Attaching portions are provided inside and outside, elastic members are arranged on both sides in the rotation direction of each elastic member attachment portion, and both end portions of the elastic member are respectively fixed to attachment surfaces formed on the rotation direction side surfaces of the respective elastic member attachment portions. Conceivable.

  For example, the present applicant has disclosed a composite vibration type bowl feeder having such an arrangement of elastic members in an application (Japanese Patent Application No. 2011-169155) prior to the present application. As shown in FIGS. 1 to 3, which is also the first embodiment of the present invention, this bowl feeder has a bowl 1 having a spiral component conveying path 1a formed on the inner surface on the upper surface of a disk-shaped upper vibrator 2. A cross-shaped movable frame 4 connected to the upper vibrator 2 by a first leaf spring (rotation vibration leaf spring) 3 as an elastic member for rotational vibration, A lower vibration part 7 comprising a lower vibration body 6 connected to a movable frame 4 by a second leaf spring 5 as an elastic member for vertical vibration is installed, and between the upper vibration body 2 and the lower vibration body 6, A first vibration mechanism 8 that generates vibration in the horizontal rotation direction and a second vibration mechanism 9 that generates vibration in the vertical direction are provided.

The rotary vibration leaf springs 3 are disposed so as to extend in the horizontal direction on both sides in the rotational direction of the legs 2a and the arms 4a, along the horizontal virtual reference line X extending radially from the rotation center Z of the Both ends of the rotary vibration leaf spring 3 are fixed to mounting surfaces 2b and 4b formed on the side surfaces in the rotational direction of the legs 2a and the arms 4a, respectively, to ensure rigidity.

JP-A-57-67410

  In the vibratory bowl feeder of the above-mentioned prior application, as shown in FIG. 12, the rotational vibration leaf spring 3 extending in the horizontal direction is parallel to the virtual reference line X extending radially from the rotation center Z of both vibrating bodies 2 and 6. And spaced apart in the horizontal direction.

  Here, in FIG. 12, assuming that the base end position of the fixed span L of the rotational vibration leaf spring 3 is the point O and the distal end position is the point A, the rotational vibration leaf spring 3 is assumed to be the upper vibration as shown in FIG. If not fixed to the body 2, the locus T of the rotational vibration at the point A on the leaf spring 3 side centered on the point O is the upper vibration body 2 centered on the rotational center Z of both the vibrators 2, 6. The trajectory T ′ of the rotational vibration at the point A on the side intersects at a position without vibration. However, since the actual rotational vibration leaf spring 3 is fixed to the upper vibration body 2, during vibration, the point A on the leaf spring 3 side is deformed so as to coincide with the point A on the upper vibration body 2 side. When a point approaches the virtual reference line X, a tensile force acts, and when point A moves away from the virtual reference line X, a compressive force acts. If the amplitude of vibration increases, the deformation of the rotational vibration leaf spring 3 and the stress caused thereby increase, and the stress load on the rotational vibration leaf spring 3 may increase due to the tensile force. Further, the elastic member mounting portion to which both ends of the rotational vibration leaf spring 3 are fixed, that is, the leg 2a of the upper vibration body 2 and the arm 4a of the movable frame 4 also receive a tensile force from the rotational vibration leaf spring 3, Stress may increase. For this reason, it has been difficult for this vibratory bowl feeder to increase the amplitude and improve the component supply capability.

  Accordingly, an object of the present invention is to improve the component supply capability by reducing the stress burden on the elastic member in the vibration type bowl feeder provided with the elastic member extending in the horizontal direction and vibrating in the horizontal rotation direction. To do.

  In order to solve the above problems, the present invention includes a bowl in which a spiral component conveyance path is formed, an upper vibrator to which the bowl is attached, and a lower vibrator installed below the upper vibrator. A lower vibration section, an elastic member that connects the upper vibration body and the lower vibration section, and an excitation mechanism that applies vibrations to the upper vibration body and the lower vibration body. The elastic member mounting portions are provided inside and outside along a horizontal virtual reference line extending radially from the rotation center of the two vibrating bodies, and a mounting surface is formed on a side surface in the rotation direction of each of the elastic member mounting portions. Is a vibration-type bowl feeder that extends in the horizontal direction and has its both end portions fixed to the mounting surfaces of the respective elastic member mounting portions so as to vibrate in the horizontal rotation direction. On the other hand Fixing the position of the elastic member mounting portion of those employing the configuration disposed with a predetermined angle in a horizontal plane so as to be closer than a fixed position outside of the elastic member mounting portion.

According to the above configuration, as shown in FIG. 14, if the base end position of the fixed span of the elastic member is point O and the tip position is point A, the elastic member is not fixed to the outer elastic member mounting portion. In this case, the rotational vibration trajectory T at the point A on the elastic member side centered on the point O is higher than that in the conventional case where the elastic member is arranged in parallel with the virtual reference line X (see FIG. 13). Since this is close to the rotational vibration trajectory T ′ at point A on the outer elastic member mounting portion side around the rotation center Z of the vibrating body, the actual elastic member is fixed to the outer elastic member mounting portion. When vibrating, the tensile force acting on the elastic member is smaller than in the case of FIG. 13, and the stress load on the elastic member and the elastic member mounting portion can be reduced.

  Here, with respect to the elastic member and its arrangement, the attachment surface of each elastic member attachment portion is formed to form the predetermined angle with the virtual reference line, and the elastic member is a flat plate spring. Can do. On the other hand, a mounting surface of each elastic member mounting portion is formed in parallel with the virtual reference line, and the elastic member is formed between the both end portions formed in parallel with each other and the flat plate forming the predetermined angle with the both end portions. Or a mounting surface of each elastic member mounting portion is formed in parallel with the virtual reference line, the elastic member is a flat plate spring, and the plate spring is elastically deformed. If it is fixed to the respective elastic member mounting portions in the state, the mounting surface of each elastic member mounting portion can be easily processed, and the processing cost can be reduced.

  Further, if the outer elastic member mounting portion is constituted by a spacer forming the mounting surface and the mounting portion main body so that the mounting portion main body does not directly contact the elastic member, the wear of the mounting portion main body And maintenance can be performed simply by replacing the spacer.

  The elastic members are arranged on both sides in the rotational direction of the elastic member attachment portions, and two elastic member attachment portions provided inside and outside along the virtual reference line, and the two elastic member attachment portions. It is desirable to arrange the elastic coupling mechanism, which is a pair of elastic members fixed to the mounting surface, at equal intervals in the rotational direction of the two vibrators, which leads to improved stability of the component conveying operation.

  The inner elastic member mounting portion is formed by integrally forming a base portion and a tip portion having different height positions, and the mounting surface is formed at the tip portion, or the inner elastic member mounting portion. If the base portion of the tip is formed thinner than the portion where the mounting surface of the tip portion is formed, the deflection of the inner elastic member mounting portion during vibration increases, and the elastic member and each elastic member mounting portion The acting tensile force can be reduced, and the vibration amplitude can be further increased.

  As the vibration mechanism, an electromagnetic vibration mechanism composed of an electromagnet and a movable iron core or a piezoelectric drive vibration mechanism driven by a piezoelectric element attached to the elastic member can be used.

  According to the present invention, the elastic member is a leaf spring, the leaf spring is inclined with respect to a vertical plane, and the vibrating bowl feeder in which the lower vibrating portion is configured only by the lower vibrating body, or the lower vibrating portion is rotated horizontally. Effectively for a complex vibration type bowl feeder comprising a movable frame connected to the upper vibrating body by an elastic member that vibrates in the direction and a lower vibrating body connected to the movable frame by a second elastic member for vertical vibration. Can be applied.

  As described above, the vibratory bowl feeder according to the present invention has an elastic member that extends in the horizontal direction and vibrates in the horizontal rotation direction with respect to a horizontal virtual reference line that extends radially from the rotation center of the upper vibrator and the lower vibrator. Since the inner fixed position is closer to the outer fixed position than the outer fixed position, it is arranged at a predetermined angle in the horizontal plane. The tensile force acting on the elastic member is small, and the stress load on the elastic member is small. Therefore, it is possible to increase the speed of component conveyance by increasing the amplitude of vibration and improve the component supply capability.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The basic structure of the vibrating bowl feeder of the first embodiment is the same as that of the prior application (Japanese Patent Application No. 2011-169155) as described above. That is, as shown in FIGS. 1 to 3, the bowl 1 having a spiral part conveyance path 1 a formed on the inner surface is attached to the upper surface of the disk-shaped upper vibrating body 2, and the upper vibrating body 2 has an upper portion below the upper vibrating body 2.

  The bowl 1 is separated into a separation bottom 12 that forms the bottom of the bowl 1 and a bowl main body 13 that is attached to the upper vibrating body 2. A gap is provided between the separation bottom 12 and the bowl main body 13. Both are not in contact with each other. Further, the separation bottom 12 has a cylindrical portion 12a at the center thereof, and the cylindrical portion 12a is rotatably fitted to a support shaft 14 standing on the upper surface of the lower vibrating body 6 so that the lower vibrating body 6 can be rotated. It is supported by.

  The upper vibrator 2 is provided with four legs (elastic member mounting portions) 2a at equal intervals in the circumferential direction on the lower surface side of the outer peripheral portion, and the entire side surfaces on both sides in the rotational direction of each leg 2a are the first leaf springs. 3 is a mounting surface 2b for fixing 3.

  Further, as shown in FIGS. 2 and 4, the movable frame 4 of the lower vibrating portion 7 has four arms (elastic member mounting portions) extending radially from the central portion through which the cylindrical portion 12 a of the separation bottom 12 of the bowl 1 passes. ) 4a is formed in a cross shape formed at equal intervals in the circumferential direction, and mounting surfaces 4b for fixing the first leaf springs 3 are formed on the side surfaces on both sides in the rotational direction of each arm 4a. On the other hand, two spring receiving portions 6a and 6b having different heights for fixing the second leaf spring 5 are provided on the upper surface of the lower vibrating body 6 (see FIG. 3).

  The first leaf spring 3 is a flat plate formed of two strip springs with the front and back surfaces oriented in the horizontal direction, one on each side in the rotational direction of each arm 4a of the movable frame 4 in the horizontal direction. It is arranged to extend. Then, one end thereof is fixed to the mounting surface 4b of each arm 4a of the movable frame 4, and the other end is fixed to the mounting surface 2b of the leg 2a of the upper vibrator 2, so that the upper vibrator 2 is moved in the horizontal rotation direction. It is a rotational vibration leaf spring that is supported so as to vibrate.

  Here, as shown in FIG. 5, the legs 2 a of the upper vibrating body 2 and the arms 4 a of the movable frame 4 of the lower vibrating section 7 are horizontal virtual reference lines extending radially from the rotation center Z of both vibrating bodies 2, 6. Each of the mounting surfaces 2b and 4b is formed along the X and has a predetermined angle θ with the virtual reference line X (in the figure, an angle formed with a straight line parallel to X is shown). As a result, the rotational vibration leaf spring 3 is fixed to the arm (inner elastic member attachment portion) 4a of the movable frame 4 with respect to the virtual reference line X. Part) is arranged in a state of forming the predetermined angle θ in the horizontal plane so as to be closer to the fixed position to 2a.

  The second leaf spring 5 is a rectangular frame formed by superposing eight belt-like springs with the front and back surfaces oriented in the vertical direction two by two, and at the four corners, the belt-like springs forming two adjacent sides. The ends of the are overlapped. And it arrange | positions horizontally so that the movable frame 4 may be pinched | interposed by a pair of upper and lower sides, and each four corner part is screwed to the upper and lower surfaces of the front-end | tip of each arm 4a of the movable frame 4. Further, the bolt 16 is passed through the pipes 15a and 15b for maintaining the central portion of each side and the vertical interval thereof, and the bolt 16 is screwed into the spring receiving portions 6a and 6b of the lower vibrating body 6 so that each side Is fixed to the lower vibrating body 6 to serve as a vertical vibration leaf spring that supports the movable frame 4 so as to vibrate in the vertical direction (see FIG. 3).

  The first vibrating mechanism 8 is attached to the lower surface of the upper vibrating body 2 so as to face the AC electromagnet 17 installed on the upper surface of the lower vibrating body 6 and to face the electromagnet 17 at a predetermined horizontal interval. The electromagnet 17 is composed of a movable iron core 18, and the electromagnet 17 and the movable iron core 18 are arranged so that an electromagnetic attractive force acts on the same horizontal plane as the rotational vibration plate spring 3. On the other hand, the second vibration mechanism 9 is arranged on the lower surface of the upper vibrating body 2 so as to face the AC electromagnet 19 installed on the upper surface of the lower vibrating body 6 with a predetermined vertical interval. It is an electromagnetic type composed of a movable iron core 20 to be attached.

  When the electromagnets 17 and 19 of the respective excitation mechanisms 8 and 9 are energized, intermittent electromagnetic attractive force acts between the electromagnets 17 and 19 and the movable iron cores 18 and 20, and these electromagnetic attractive forces and rotational vibrations. Due to the restoring force of the plate spring 3 and the vertical vibration plate spring 5, vibrations in the horizontal rotation direction and the vertical direction are generated in the upper vibrating body 2 and the bowl 1, and the components supplied to the bowl 1 are spirally transported 1a. It is conveyed along.

  This vibrating bowl feeder has the above-described configuration, and the inner fixed position of the rotary vibration leaf spring 3 with respect to the horizontal virtual reference line X extending radially from the rotation center Z of both vibrating bodies 2 and 6 is set. Since it is arranged with a predetermined angle θ in the horizontal plane so as to be closer to the outer fixed position, compared to the case where it is arranged in parallel with the virtual reference line X, the rotational vibration leaf spring 3 at the time of vibration is arranged. The trajectory in the virtual free state of the outer fixed position is close to the trajectory in the actual fixed state (see FIGS. 13 and 14). For this reason, the tensile force acting on the rotary vibration leaf spring 3 and the elastic member mounting portions 2a and 4a that fix the same is small during vibration, and the stress load on these parts can be reduced. Therefore, the vibration amplitude is increased. Therefore, the parts can be transported at high speed and the parts supply capacity can be improved.

  The rotational vibration leaf springs 3 are elastic member mounting portions provided inside and outside along one virtual reference line X, that is, on both sides in the rotational direction of the legs 2a of the upper vibration body 2 and the arms 4a of the movable frame 4. An elastic coupling mechanism that is fixed to the mounting surfaces 2b and 4b and includes the two elastic member mounting portions 2a and 4a and the two rotational vibration leaf springs 3 as a set is the rotational direction of the vibrating bodies 2 and 6. Since the parts are arranged at regular intervals, the stability of the parts conveying operation is also high.

  In the first embodiment described above, the plate-like rotational vibration leaf spring 3 is fixed to the attachment surfaces 2b and 4b of the elastic member attachment portions 2a and 4a that form a predetermined angle θ with the virtual reference line X. As in the modification shown in FIG. 6, each mounting surface 2b, 4b is formed in parallel with the virtual reference line X, and as an elastic member for rotational vibration, between both end portions 21a, 21a formed in parallel with each other, A leaf spring 21 having a flat plate portion 21b that forms a predetermined angle θ with both end portions 21a and 21a may be used. If it does in this way, processing of mounting surfaces 2b and 4b of each elastic member mounting part 2a and 4a will become easy, and reduction of processing cost can be aimed at.

  Further, in the modification shown in FIG. 7, the mounting surfaces 2b and 4b are formed in parallel to the virtual reference line X as in the example of FIG. The part is fixed to each mounting surface 2b, 4b in a state where it is elastically deformed so as to form a predetermined angle θ with both ends. Here, the outer elastic member mounting portion, that is, the leg 2a of the upper vibrating body 2 is composed of a spacer 2c that forms the mounting surface 2b and a mounting portion main body 2d. Therefore, as in the example of FIG. 6, the processing cost of each elastic member attachment portion 2a, 4a can be reduced, and the leg 2a of the upper vibration body 2 is connected to the leaf vibration member 3 for rotational vibration when the attachment portion main body 2d vibrates. Wear due to friction does not occur, and maintenance can be performed only by replacing the spacer 2c.

  8 and 9A and 9B show a modification of the shape of the movable frame. In this modified example, the arm (inner elastic member mounting portion) 22a of the movable frame 22 is formed by integrally forming a root portion 22b and a tip portion 22c having different height positions, and the tip portion 22c An attachment surface 22d for fixing one end of the rotational vibration leaf spring 3 is formed on both side surfaces in the rotational direction. Further, the width dimension B1 of the root portion 22b is formed narrower than the width dimension B2 of the portion where the attachment surface 22d of the tip end portion 22c is formed. According to this configuration, the tip 22c of the arm 22a is easily displaced radially outward with the arm bottom (Y point in FIG. 9B) as a fulcrum, and the rigidity of the root 22b is reduced. The deflection of the entire arm 22a at the time of vibration can be increased, and the tensile force acting on the rotational vibration leaf spring 3 and the elastic member mounting portions 2a and 22a to which both ends thereof are fixed can be further reduced.

  FIG. 10 shows a second embodiment. In this vibrating bowl feeder, the movable frame 4, the second leaf spring 5, and the second vibration mechanism 9 of the first embodiment are omitted, and the lower vibrating portion 7 is configured only by the lower vibrating body 6. One leaf spring 3 is inclined with respect to a vertical plane, and one end thereof is fixed to an arm (inner elastic member mounting portion) 6c extending upward from the upper surface of the lower vibrating body 6. The first vibration mechanism 8 vibrates the bowl 1 in the horizontal rotation direction and the vertical direction. In order to fix the first leaf spring 3 in an inclined state, the leg 2 a of the upper vibration body 2 and the arm 6 c of the lower vibration body 6 are inclined in accordance with the posture of the first leaf spring 3. Is formed.

  And although illustration is abbreviate | omitted, the 1st leaf | plate spring 3 makes a predetermined angle with respect to the horizontal virtual reference line extended radially from the rotation center of both the vibrating bodies 2 and 6 similarly to 1st Embodiment. Therefore, it is possible to reduce the stress load on the first leaf spring 3 and the elastic member mounting portions 2a and 6c to which both ends thereof are fixed, and increase the vibration amplitude to improve the component supply capability. Can be planned.

  In each of the embodiments described above, an electromagnetic excitation mechanism composed of an electromagnet and a movable iron core is used as the first and second excitation mechanisms. However, as shown in FIG. A piezoelectric drive type excitation mechanism driven by the piezoelectric element 23 can also be used.
