Description

Vibrating parts conveying device

The present invention relates to a vibrating component conveying apparatus that conveys a component by vibrating a component conveying member by driving of a vibration oscillating mechanism.

In the vibrating component conveying apparatus, the composite vibrating type is configured such that the intermediate vibrating body and the base are connected to the horizontal vibrating leaf spring in the vertical direction in order to provide the component conveying member with the vibration suitable for the component conveying. In the direction of the vertical vibration, the component transfer member and the intermediate vibrating body are connected to each other, and the vibration of the component transfer member in the horizontal direction (part transfer direction) and the vibration in the vertical direction can be adjusted (for example, see Patent Document 1).

However, in the composite vibration type component conveying apparatus described above, since the leaf spring for horizontal vibration is fixed at two fixed positions in the vertical direction, vibration is generated in the vertical direction even when vibrating in the horizontal direction. Further, in general, the center of gravity G of the component transporting member (including the upper vibrating body or the like) is different from the fulcrum in the height direction. Therefore, when the component transporting member is displaced in the horizontal direction, a rotational motion around the center of gravity G occurs (hereinafter , called "pitch motion"). Therefore, it is practically impossible to impart the required vibration to the component conveying member, and it is difficult to carry out the problem of stable component transportation.

In response to this, the present applicant has developed a technique in which the horizontal vibration elastic member (a leaf spring or the like) is fixed at two fixed positions on the same horizontal line orthogonal to the component conveying direction, so that the deformation in the horizontal direction is not The displacement in the vertical direction is associated with the suppression of the vibration in the vertical direction due to the vibration in the horizontal direction (the component conveying direction) (Patent Document 2).

On the other hand, in the component-transporting apparatus of the composite vibration type, the two types of vertical vibration leaf springs are provided as one set, and the rigid part structure is formed together with the component transfer member and the intermediate vibrating body. The way it is configured while preventing the pitching motion.

Further, in Patent Document 2, the arrangement of the leaf springs for horizontal vibration may be two or more. Therefore, for example, the vibration type component conveying device in which the horizontal vibration leaf springs are disposed as shown in Figs. 15 to 17 is considered. In the component transporting apparatus, an intermediate vibrating body 54 is provided between the upper vibrating body 52 and the base 53 with a groove (part transporting member) 51 having a linear transport path 51a, and is connected by two horizontal vibration leaf springs 55. In the intermediate vibrating body 54 and the base 53, the upper vibrating body 52 and the intermediate vibrating body 54 are connected by the four vertical vibration leaf springs 56, and the vibration in the horizontal direction (the component conveying direction and the X direction in the drawing) is generated. The oscillating mechanism 57 and the second oscillating mechanism 58 that generates vibration in the vertical direction (the Z direction in the drawing). The two horizontal vibration leaf springs 55 are fixed to one side of the base 53 so as to be fixed to the same horizontal line orthogonal to the component transport direction (X direction). The leaf spring mounting portion 53a of the lower side of FIG. 16 and the left side of FIG. 17 is fixed to the other end portion. The leaf spring mounting portion 54a is placed on the other side (the upper side of FIG. 16 and the right side of FIG. 17) of the intermediate vibrating body 54.

In the component transport apparatus in which the horizontal vibration leaf spring 55 is disposed as described above, since the positional relationship between the fixed position of the horizontal vibrating body 54 of each of the horizontal vibration leaf springs 55 and the fixed position of the base 53 is the same, When the intermediate vibrating body 54 is oscillated in the component conveying direction (X direction), as shown in FIG. 18, the horizontal vibration leaf spring 55 generates an amplitude not only in the X direction but also in the horizontal plane (Y direction) orthogonal to the X direction. For the vibration of y. Further, the vibration in the Y direction is transmitted to the groove 51 to cause the components on the conveying path 51a to snake, resulting in a substantial reduction in the component conveying speed. Further, by imparting vibration in the Y direction to the groove 51 in addition to the vibration in the X direction and the Z direction, it is difficult to adjust the vibration of the groove 51 to be optimal for component transportation.

In the case of the component transport apparatus in which the vertical vibration leaf spring is disposed as proposed in Patent Document 3, when the component transport member is lengthened or the quality is increased by the characteristics of the transported component or the structure of the component supply target. Since the moment of the center of gravity G around the component conveying member becomes large, a pitching motion is also generated. Further, when the component conveying member has an asymmetrical shape and the position of the center of gravity G is shifted from the suction position of the electromagnet constituting the oscillating mechanism, the attraction force acts on the position shifted from the center of gravity G. This attraction produces a moment about the center of gravity G, resulting in a pitching motion.

On the other hand, in the general composite vibration type component conveying device described in Patent Document 1, etc., an anti-vibration member such as an anti-vibration rubber or a coil spring is provided between the base and the ground in order to transmit the vibration to the outside. The reaction force of the attractive force generated by the electromagnet of the vibration-increasing mechanism or the accompanying part transfer structure The reaction of the action of the piece also produces a moment about the center of gravity G' of the abutment, resulting in a pitching motion. The pitching motion about the center of gravity G' of the base affects the vibration of the component conveying member, and produces a pitching motion about the center of gravity G of the component conveying member.

As described above, in the conventional composite vibrating component conveying apparatus, there is a fear that the occurrence of the pitching motion of the center of gravity G around the component conveying member cannot be reliably suppressed, and the component conveying member cannot be produced due to the occurrence of the pitching motion. The vibration in the horizontal direction and the vibration in the vertical direction are adjusted to the required state, and the component transportation becomes unstable.

An object of the present invention is to provide a component-transporting device with a vibration suitable for component transfer in a component-transporting device.

In order to solve the problem, the vibrating component conveying device of the present invention includes a component conveying member in which a component conveying path is formed, a vibrating body on which the component conveying member is attached, a base provided on the floor, and the upper vibrating body and the base. An intermediate vibrating body between the stages, a first elastic member that connects the intermediate vibrating body and the base, and a second elastic member that connects the upper vibrating body and the intermediate vibrating body; and the vibrating component transporting device is the first one One of the elastic member and the second elastic member is a horizontal vibration elastic member, and the other is a vertical vibration elastic member, and the horizontal vibration member and the first vibration mechanism provide a horizontal direction to the component transfer member. The vibration for the vertical direction is applied to the component conveying member by the elastic member for vertical vibration and the second oscillating mechanism, and the plurality of elastic members for horizontal vibration are provided in the component conveying direction. The fixed position of the intermediate vibrating body and the fixed position to the base or the upper vibrating body are located in the direction in which the component is transported The same level of delivery, and the relationship between the position of the fixed location at a 2 to replace part of the conveyance direction are alternately arranged. Thereby, it is possible to suppress the vibration in the vertical direction (Z direction) caused by the vibration of the component conveying direction (X direction) of the horizontal vibration elastic member E _A as shown in FIG. 19, and it is also possible to suppress the components in the horizontal plane. Since the vibration in the direction in which the conveyance direction is orthogonal is provided, it is possible to easily impart vibration required for the component conveyance member to the component conveyance.

Here, if an anti-vibration member is provided between the base and the ground, the pitching motion of the component transporting member viewed from the ground becomes a relative pitching motion of the composite component transporting member with respect to the base (hereinafter, simply referred to as " With respect to the pitching motion") and the pitching motion of the counter which is opposite to the phase, the hammer is placed on the base, and the amplitude of the pitching motion of the base is brought close to the component conveying member. The mass of the base is adjusted in relation to the amplitude of the pitch motion, and the pitching motion of the component transport member viewed from the ground can be surely suppressed.

For example, when the moment acting on the component conveying member is small (when the component conveying member is short or the mass is small), since the amplitude of the relative pitching motion of the component conveying member becomes small, it is only necessary to reduce the abutment. The mass can be reduced by the amplitude of the pitch motion of the base. On the other hand, when the moment acting on the component conveying member is large (when the component conveying member is long or the mass is large), since the amplitude of the relative pitching motion of the component conveying member becomes large, it is only necessary to increase Increase the quality of the abutment and increase the pitch of the abutment The amplitude of the motion can be.

In addition, even if the mass of the component conveying member is adjusted, the same effects as described above can be obtained. However, when the mass of the component conveying member is increased, the natural vibration frequency of the component conveying member is reduced, and the natural vibration frequency is set. The driving frequency (vibration frequency) in the vicinity is also low, the moving speed of the parts is slowed, or the load on the electromagnet of the vibration absorbing mechanism is increased, so it is desirable to adjust the mass of the base.

The hammer may be provided to include a plurality of hammers, and the mass can be adjusted by increasing or decreasing the number of the hammers, and it is desirable to provide the end portions of the base. The reason for this is that the farther the mass of the base changes, the farther from the center of gravity, the greater the influence of the increase or decrease of the mass on the amplitude of the pitching motion, and the quality adjustment becomes easier.

Further, the above hammer is desirably provided at a plurality of places. The reason is that if only the mass of one of the bases is changed, the center of gravity of the base moves, and the center of the pitch motion is shifted and it is difficult to adjust. However, if the position of the hammer is plural, the center of gravity of the base can be Move the way to adjust the quality of the hammer. On the contrary, by adjusting the mass of the hammer provided at the plurality of places and moving the position of the center of gravity of the base to the vicinity of the center of the apparatus, it is also possible to stabilize the transport operation. Further, even if the installation position of the hammer can be adjusted in the vertical direction, the center of gravity of the base can be moved to the vicinity of the center of the apparatus to obtain a stable conveyance operation.

On the other hand, the elastic member for vertical vibration may be fixed at two fixing positions on the same horizontal line orthogonal to the component conveying direction, or may be fixed at two fixing positions on the same horizontal line parallel to the component conveying direction.

In addition, the natural vibration frequency of the horizontal vibration elastic member is different from the vertical direction in the horizontal direction, or the rigidity of the horizontal vibration elastic member in the vertical direction is higher than the rigidity in the horizontal direction, thereby being more effectively suppressed. Vibration in the vertical direction due to vibration in the horizontal direction.

In the above-described configuration, as the horizontal vibration elastic member, a leaf spring may be used in which the front and back surfaces are directed toward the component conveying direction. However, it is also desirable to use a plurality of leaf springs that face the component backing direction in the component conveying direction. A spacer is provided between the fixed portions of the leaf spring. The reason is that when the moment acts on the intermediate vibrating body by the inclination of the first oscillating mechanism or the like, if the elastic member for horizontal vibration is a leaf spring having a low torsional rigidity, as shown in FIG. 20 The leaf spring E _{B is} twisted, and this torsion is a torsional vibration accompanying the vibration in the horizontal direction, and the intermediate vibrating body is subjected to the pitch vibration with respect to the component conveying direction, so that it is difficult to achieve the vibration required for the most suitable component transportation. In other words, by using the elastic member for horizontal vibration in which the spacer is sandwiched by a plurality of leaf springs, the horizontal vibration can be suppressed as shown in FIG. 21 even when a moment acts on the intermediate vibrating body. The torsion of the elastic member E _C makes it easy to achieve the desired vibration.

On the other hand, as the elastic member for vertical vibration, a leaf spring having a front and back faces facing in the vertical direction can be used.

Each of the oscillating mechanisms includes an electromagnet and a movable iron core, and a reference waveform generator for generating a reference waveform for applying a voltage and an amplitude for adjusting the reference waveform are provided in an applied voltage setting circuit of one of the electromagnets corresponding to one of the electromagnets. The waveform amplitude adjuster is provided in the applied voltage setting circuit of the electromagnet corresponding to the other one, and is provided to have a specificity with respect to the reference waveform. The phase difference adjuster of the phase difference waveform and the waveform amplitude adjuster for adjusting the amplitude of the waveform generated by the phase difference adjuster can freely control the waveform, period, phase difference, and amplitude of the applied voltage to each electromagnet. It is easy to make the horizontal vibration and the vertical vibration close to the required vibration.

Further, a PWM signal for converting a waveform obtained by adjusting the amplitude of each of the waveform amplitude adjusters to a PWM (Pulse Width Modulation) signal is provided in an applied voltage setting circuit of the electromagnets corresponding to the respective vibration absorbing mechanisms. The generator and the vibration absorbing mechanism can be driven in a PWM manner.

In the vibrating component conveying device of the present invention, as described above, the horizontal vibrating elastic member that connects the upper vibrating body, the base, and the intermediate vibrating body is fixed to the intermediate vibrating body and to the base or the upper vibrating body. The fixed position is located on the same horizontal line orthogonal to the component conveying direction, and the position is alternately changed in the component conveying direction, so that the vertical direction due to the vibration of the component conveying direction of the elastic member for horizontal vibration can be suppressed. Any of vibrations in the vibration and the direction perpendicular to the direction in which the parts are transported.

Moreover, by providing a hammer on the base, the mass of the base is adjusted in such a manner that the amplitude of the pitch motion of the base is close to the amplitude of the relative pitch motion of the component transport member relative to the base opposite to the base, Therefore, the pitching motion of the component conveying member viewed from the ground can be reliably suppressed, and the required vibration can be easily imparted to the component conveying member, and stable component transportation can be realized.

Hereinafter, embodiments of the present invention will be described based on the drawings. Fig. 1 to Fig. 3 show a vibrating component conveying device according to the first embodiment. The component conveying device is such that a groove (part conveying member) 1 in which the linear conveying path 1a is formed is attached to the upper surface of the upper vibrating body 2, and is disposed between the upper vibrating body 2 and the base 3 provided on the ground. In the intermediate vibrating body 4, the intermediate vibrating body 4 and the base 3 are connected by two leaf springs 5 as the first elastic members, and the upper vibrating body 2 and the intermediate vibrating body 4 are connected by four leaf springs 6 as second elastic members. The first vibration absorbing mechanism 7 that generates vibration in the horizontal direction (the component conveying direction and the X direction in the drawing) is provided between the intermediate vibrating body 4 and the base 3, and is disposed between the upper vibrating body 2 and the base 3. The second oscillating mechanism 8 that vibrates in the vertical direction (the Z direction in the drawing).

The base 3 is formed in a rectangular shape, and a columnar leaf spring mounting portion 3a is erected at two corners of the diagonal, and is supported by an anti-vibration rubber (anti-vibration member) 18 fixed to the floor surface F. Further, a coil spring or the like can also be used for the anti-vibration material.

Further, a hammer 19 is provided at each of both ends of the component 3 in the conveying direction of the base 3. Each of the hammers 19 includes a plurality of hammer pieces 19a that are detachable, and the mass can be adjusted by increasing or decreasing the number of the hammer pieces 19a. Here, although the illustration is omitted, the method of attaching the hammer 19 to the base 3 may be a method in which a through hole is provided in each of the hammer pieces 19a, and the screw is fixed by a bolt or the like. In this case, by arranging a plurality of screw holes provided in the base 3 in the height direction and adjusting the attachment position of the hammer 19 to the base 3 in the vertical direction, it is possible to easily realize the stabilization of the transport operation. The position of the center of gravity of the base 3 is moved to the vicinity of the center of the device, or the interference of the hammer 19 with other machines is avoided. Furthermore, in this embodiment, The plurality of hammer pieces 19a constitute the hammer 19, but it is also possible to use a hammer of a mass required to form a single body.

The intermediate vibrating body 4 is formed in a rectangular frame shape, and has two corners opposite to each other on the outer peripheral side of the upper end of the leaf spring mounting portion 3a of the base 3, and the inner peripheral surface faces the lower portion of the upper vibrating body 2 The way it is configured. Further, a leaf spring mounting portion 4a that protrudes from the opposite corners of the leaf spring mounting portion 3a of the base 3 in the component conveying direction (X direction) is provided on the outer peripheral surface thereof.

The first leaf spring 5 is a horizontal vibration leaf spring (horizontal vibration elastic member) such that the front and back surfaces are directed toward the component transport direction, and the fixed positions at both ends are located on the same horizontal line orthogonal to the component transport direction. One end portion is fixed to the leaf spring mounting portion 3a of the base 3, and the other end portion is fixed to the leaf spring mounting portion 4a of the intermediate vibrating body 4, and the intermediate vibrating body 4 is supported to vibrate in the horizontal direction. Here, the two leaf spring attachment portions 3a of the base 3 and the two leaf spring attachment portions 4a of the intermediate vibrating body 4 are disposed such that the straight lines connecting the installation positions of the same mounting portion are arranged in a plan view, so that two The horizontal vibration leaf spring 5 is disposed such that the position of each of the two fixed positions is changed in the component conveying direction.

Further, the horizontal vibration leaf spring 5 is such that the thickness dimension in the horizontal direction is smaller than the width dimension in the vertical direction, and the natural vibration frequency in the horizontal direction is largely different from the natural vibration frequency in the vertical direction, and the rigidity in the vertical direction is sufficiently higher than the horizontal level. The rigidity of the direction.

On the other hand, the second leaf spring 6 is a vertical spring leaf spring (vertical vibration elastic member) in which the front and back surfaces are oriented in the vertical direction, and the fixed positions of the both ends are on the same horizontal line orthogonal to the component transport direction. Square In the formula, the one end portion is fixed to the lower portion of the upper vibrating body 2, the other end portion is fixed to the longitudinal direction edge portion of the intermediate vibrating body 4, and the upper vibrating body 2 is supported by the vibration in the vertical direction.

Further, the first vibration absorbing mechanism 7 includes an AC electromagnet 9 provided on the base 3, and a movable iron core 10 attached to the intermediate vibrating body 4 so as to face the electromagnet 9 at a predetermined interval. Further, the movable iron core 10 is attached to the intermediate vibrating body 4 in this example, but may be attached to the upper vibrating body 2. On the other hand, the second vibration absorbing mechanism 8 includes an AC electromagnet 11 provided on the base 3, and a movable iron core 12 attached to the upper vibrating body 2 so as to face the electromagnet 11 at a predetermined interval. .

When the electromagnet 9 of the first oscillating mechanism 7 is energized, the intermittent electromagnetic attraction force acts between the electromagnet 9 and the movable iron core 10, and the restoring force of the electromagnetic attraction force and the horizontal vibration leaf spring 5 is On the other hand, the intermediate vibrating body 4 generates vibration in the horizontal direction, and the vibration is transmitted to the upper vibrating body 2 and the groove 1 via the vertical vibration leaf spring 6. When the electromagnet 11 of the second oscillating mechanism 8 is energized, the intermittent electromagnetic attraction force acts between the electromagnet 11 and the movable iron core 12, and the electromagnetic attraction force and the vertical vibration leaf spring 6 are restored. The force generates vibration in the vertical direction to the upper vibrating body 2 and the groove 1. Further, the components supplied to the groove 1 are conveyed along the linear conveyance path 1a by the vibration in the horizontal direction and the vibration in the vertical direction.

Therefore, the vibration in the horizontal direction and the vibration in the vertical direction of the groove 1 can be individually adjusted by setting the voltages applied to the electromagnets 9 and 11 of the respective oscillating mechanisms 7 and 8.

Figure 4 shows the application of voltage to the electromagnets 9, 11 of the respective oscillating mechanisms 7, 8. The circuit. A reference waveform generator 13 that generates a reference waveform of an applied voltage is provided in the circuit of the first oscillating mechanism 7. The reference waveform generator 13 generates a reference waveform corresponding to the type of the waveform (for example, a sine wave) and the set value of the period (frequency) of the waveform. On the other hand, a phase difference adjuster 14 that generates a waveform having a specific phase difference with respect to a reference waveform generated by the reference waveform generator 13 is provided in the circuit of the second vibration absorbing mechanism 8.

Further, in the circuits of the respective oscillating mechanisms 7, 8, the waveform generated by the reference waveform generator 13 or the phase difference adjuster 14 is adjusted to a predetermined amplitude by the waveform amplitude adjuster 15, and is converted by the PWM signal generator 16 into After the PWM signal, the voltage booster 17 boosts and applies it to each of the electromagnets 9, 11. Thereby, the waveform, the period, the phase difference, and the amplitude of the applied voltage to the electromagnets 9 and 11 can be freely controlled, and the vibration in the horizontal direction and the vibration in the vertical direction can be individually adjusted. Furthermore, the PWM signal generator 16 is not required when the respective vibration oscillating mechanisms are not driven by the PWM method.

In the vibration type component conveying device, the horizontal vibration is fixed at two fixed positions on the same horizontal line orthogonal to the component conveying direction when the intermediate vibrating body 4 vibrates by the driving of the first oscillating mechanism 7. The operation of deforming only in the horizontal direction and returning to the original state is repeated by the leaf spring 5 (refer to FIG. 19). Thereby, the vibration generated in the intermediate vibrating body 4 becomes substantially free of vibration in the vertical direction, and is only vibration in the substantially horizontal direction. In addition, since the positional relationship between the fixed positions of the two horizontal vibration leaf springs 5 is reversed in the component conveying direction, the direction orthogonal to the component conveying direction in the horizontal plane can be suppressed (FIG. 2, 3) Vibration in the Y direction).

Moreover, the horizontal vibration frequency of the leaf spring 5 for horizontal vibration is The natural vibration frequency in the vertical direction is largely different, and thus the generation of vibration in the vertical direction due to vibration in the horizontal direction can be suppressed.

In other words, in order to increase the component transport speed with a small power efficiency, in the case of the composite vibrating component transport apparatus, the natural vibration frequency in the horizontal direction of the slot is often used in many cases. The nearby frequency drives the various vibration mechanisms. In this case, when the natural vibration frequency in the horizontal direction of the leaf spring for horizontal vibration is the same as the natural vibration frequency in the vertical direction, or when the difference is only about several Hz, the vibration of the intermediate vibrating body generated by the vibration in the horizontal direction is vertical. Become a size that cannot be ignored. However, in the component transport apparatus of the embodiment, since the natural vibration frequency in the horizontal direction of the horizontal vibration leaf spring 5 and the natural vibration frequency in the vertical direction are sufficiently large, the intermediate vibrating body due to horizontal vibration can be used. The vibration suppression in the vertical direction of 4 is small.

Here, the horizontal vibration leaf spring may have a shape in which the thickness in the horizontal direction is larger than the width dimension in the vertical direction, and the natural vibration frequency in the horizontal direction may be different from the natural vibration frequency in the vertical direction, but the rigidity is as follows. From the viewpoint of the above, it is preferable to adopt the shape as in the embodiment.

That is, in this embodiment, since the horizontal direction dimension of the horizontal vibration leaf spring 5 is extremely smaller than the vertical direction dimension, the rigidity in the vertical direction is extremely higher than the rigidity in the horizontal direction, so that the vertical direction of the intermediate vibrating body 4 can be further reduced. Vibration of the direction.

As described above, in the component transport apparatus of the embodiment, the vibration generated in the vertical direction of the groove 1 is substantially the vibration generated only by the second oscillating mechanism 8 and the vertical vibration leaf spring 6, and the horizontal plane can be suppressed. Part transfer side Since the vibration is in the direction orthogonal to the direction, it is possible to easily adjust the vibration in the horizontal direction and the vibration in the vertical direction, thereby easily providing the groove 1 with the vibration required for the component to be conveyed.

FIG. 5 and FIG. 6 show a variation of the arrangement of the vertical vibration leaf springs 6 of the first embodiment. In this modification, the vertical vibration leaf spring 6 is fixed to the short side edge portion of the upper vibrating body 2 and the intermediate vibrating body 4 at two fixed positions on the same horizontal line parallel to the component conveying direction (X direction in the drawing). .

Next, the action of the hammer 19 in the above-described first embodiment will be described based on Figs. 7 to 12 . Fig. 7 shows a simplified model of the composite vibrating parts conveying device. The upper rigid body A of the simple model corresponds to the groove 1 (including the upper vibrating body 2) of the first embodiment. Further, the spring Ka corresponds to the vertical vibration leaf spring 6, the lower rigid body B corresponds to the intermediate vibrating body 4 and the base 3, and the spring Kb corresponds to the anti-vibration rubber 18. Further, the center of gravity Ga represents the center of gravity of the upper rigid body A, and the center of gravity Gb represents the center of gravity of the lower rigid body B. In addition, the intermediate vibrating body 4 and the base 3 are actually connected by the horizontal vibration leaf spring 5, but since the horizontal vibration leaf spring 5 does not function in the vertical direction, this simple model is not considered.

When the above-described simple model is used to indicate the vibration operation in the vertical direction of the general composite vibrating component conveying device, as shown in FIGS. 8(a) and 8(b), the upper rigid body A is tilted around the center of gravity Ga, and the lower rigid body B is The pitching motion is performed around the center of gravity Gb. Fig. 8(a) shows the case where the amplitude of the relative pitch motion of the upper rigid body A with respect to the lower rigid body B is smaller than the amplitude of the pitch motion of the lower rigid body B, and Fig. 8(b) is the opposite of Fig. 8(a). .

Fig. 9 is a view showing the vertical position of the upper portion A1 of the rigid body A and the B1 point of the lower rigid body B in Fig. 7 when the component conveying apparatus performs the vibration operation of Fig. 8(a). Temporal change in directional displacement. The dotted line in Fig. 9 is the relative displacement of the A1 point observed from the point B1 (the relative pitch motion of the upper rigid body A), and the absolute displacement of the single point chain line from the ground point B1 (the vertical movement of the lower rigid body B) The solid line is the absolute displacement of the A1 point observed from the ground (the pitch motion of the upper rigid body A) (the same applies to FIGS. 10 to 12 below). The relative displacement of point A1 is opposite to the absolute displacement of point B1. Its synthesis is the absolute displacement of point A1. In this case, in the component transport apparatus according to the first embodiment, by reducing the mass of the lower rigid body B (the mass of the hammer 19 provided on the base 3), as shown in Fig. 10, the pitch of the lower rigid body B can be reduced. The amplitude of the motion is close to the amplitude of the relative pitch motion of the upper rigid body A, suppressing the pitching motion of the upper rigid body A.

Fig. 11 is a view showing temporal changes in the vertical displacement of the A1 point of the upper rigid body A and the B1 point of the lower rigid body B when the component conveying device performs the vibration operation of Fig. 8(b). In this case, in the component transport apparatus according to the first embodiment, by increasing the mass of the lower rigid body B (the mass of the hammer 19 provided on the base 3), as shown in FIG. 12, the longitudinal body of the lower rigid body B can be increased. The amplitude of the rocking motion is close to the amplitude of the relative pitching motion of the upper rigid body A, and the pitching motion of the upper rigid body A is suppressed.

Further, in actuality, as the pitching motion of the upper rigid body A is reduced and the pitching motion of the lower rigid body B is also reduced, the relative displacement of the A1 point and the absolute displacement of the B1 point shown in Figs. 10 and 11 are also reduced.

As described above, in the component transport apparatus of the embodiment, the anti-vibration rubber 18 is provided between the base 3 and the floor F, and the hammer 19 is provided on the base 3, and the amplitude of the pitch motion of the base 3 is close to The quality of the base 3 is adjusted in such a manner that the anti-phase slot 1 is relative to the amplitude of the relative pitch motion of the base 3, whereby The pitching motion of the groove 1 observed from the ground is surely suppressed, so that stable parts can be conveyed.

Fig. 13 and Fig. 14 show a second embodiment. In the embodiment, the intermediate vibrating body 4 and the base 3 are coupled to the horizontal vibration elastic member 20 in place of the horizontal vibration leaf spring 5 of the first embodiment. The horizontal vibration elastic member 20 is arranged such that the two leaf springs 21 facing the component conveying direction are arranged along the component conveying direction, and the spacer 22 is provided between the fixing portions of the leaf springs 21, and the first embodiment is provided. Similarly, the horizontal vibration springs 5 are fixed at two fixed positions on the same horizontal line orthogonal to the component conveying direction, and the positions of the two fixed positions are arranged to be reversed in the component conveying direction. Further, the vertical vibration leaf spring 6 is fixed to the short side of the upper vibrating body 2 and the intermediate vibrating body 4 at two fixed positions on the same horizontal line parallel to the component conveying direction, similarly to the example shown in Figs. 5 and 6 . Direction edge. The configuration of the other portions includes an applied voltage setting circuit for the electromagnets 9 and 11 of the respective oscillating mechanisms 7, 8 as in the first embodiment.

In the component transport apparatus according to the second embodiment, since the torsional rigidity of the horizontal vibration elastic member 20 is higher than that of the horizontal vibration leaf spring 5 of the first embodiment, even when the first vibration absorbing mechanism 7 is installed, the tilting or the like is performed. When the moment acts on the intermediate vibrating body 4, the horizontal vibration elastic member 20 is not twisted, but is deformed only in the horizontal direction (see Fig. 21). Therefore, in the apparatus of the first embodiment, it is possible to easily obtain the vibration required for the component transfer as compared with the case where the torsion of the horizontal vibration leaf spring 5 is generated (see FIG. 20).

Further, in the second embodiment, as in the example shown in Figs. 1 to 3, the vertical vibration leaf spring 6 can be made orthogonal to the component conveying direction. The two fixed positions on the horizontal line are fixed to the longitudinal direction edge portions of the upper vibrating body 2 and the intermediate vibrating body 4.

In the above-described embodiments, the first leaf spring that connects the intermediate vibrating body and the base is used as a leaf spring for horizontal vibration, and the second leaf spring that connects the upper vibrating body and the intermediate vibrating body is used as a leaf spring for vertical vibration. On the other hand, the first leaf spring is a leaf spring for vertical vibration, and the second leaf spring is configured as a leaf spring for horizontal vibration. Further, the leaf springs are arranged one by one, but one or two or more sheets may be used as one.

Further, the horizontal vibration leaf springs are disposed at two locations, but may be composed of three or more. In this case, the positional relationship between the fixed position of the intermediate vibrating body and the fixed position of the base is also applied to the component transport direction.
