Description

Parts feeder

The present invention relates to a parts feeder for conveying a plurality of workpieces in a specific form in a predetermined posture on a conveying path.

In the past, there is known a parts feeder that is equipped with a conveying path for conveying objects such as electronic parts to the supply destination, and using vibration or other means to align the conveyed objects along the conveying path. , And supply to the downstream supply target (for example, refer to Patent Document 1).

This kind of parts feeder is provided with a fixed part, a movable part connected to a basin, a drive spring that connects the fixed part and the movable part to each other and elastically supports the movable part to the fixed part, and a vibration source. The vibrating force imparted by the vibration source directly or indirectly vibrates the driving spring, causing the movable part and the fixed part to vibrate relative to each other, and the vibration is transmitted to the basin integrally connected with the movable part to be set on the basin On the conveying road, vibration conveying of the conveyed objects.

In the conventional parts feeder, for example, a plate-shaped spring (plate spring) is used as a driving spring. The springs are tied so that their thickness It is arranged in a posture in which the degree direction coincides with the conveying direction. In addition, a pair of drive springs are arranged in a predetermined inclined posture in order to prevent ‧ restraining the swing phenomenon or rolling phenomenon of the object to be conveyed on the conveying path of the basin.

In addition, the vibrating force applied from the vibration source (not shown in the figure) causes the movable part to vibrate to the fixed part, thereby causing the bowl connected to the movable part to also vibrate, so that the conveyed object is moved along the conveying direction Transport on the downstream side.

In addition, in the conventional parts feeder, the driving spring is directly or indirectly vibrated by a vibration source, and the movable part and the fixed part can be bent into an S-shape by the driving spring itself. The two are relatively displaced.

Therefore, according to this structure, the pair of driving springs are flexed and deformed into an S-shape, thereby causing the movable portion and the fixed portion to also bend, and as a result, the basin fixed to move integrally with respect to the movable portion also bends. It is considered that there may be deviations in the conveying speed, etc., which may hinder stable conveying processing. In particular, in conventional parts feeders that use S-shaped deformed drive springs during vibration (power ON state), in order to realize high-speed vibration transfer, the vibration frequency must be increased, and the thickness of the drive spring must be set The larger the value (the thicker), the greater the deflection of the basin.

Here, after considering the S-shaped deformation of the driving spring, the movable part and the fixed part are processed with high precision to try to reduce the deflection of the groove, but the processing accuracy of the movable part and the fixed part is relatively high. If it is low, the driving spring will be twisted, which will cause the bowl to flex.

In addition, in the conventional parts feeder, since the drive spring is deformed in an S-shape, for example, the amount of displacement from the point of time before the deformation to the point of maximum deformation is compared with that of a bow-shaped deformed spring. It is about half, and the vibration attenuation is also large, so the vibration amplification rate of resonance is small, and there is room for improvement from the viewpoint of efficiency.

The present invention aims to effectively solve the above-mentioned problems, and aims to provide a parts feeder, which vibrates on a completely different vibration principle from the conventional parts feeder, and can convey objects efficiently and stably.

In view of the above problems, the present invention adopts the following means.

That is, the parts feeder of the present invention is characterized by comprising: a basin having a substantially circular shape when viewed from above; a movable part fixed to the upper end of the basin; and a vibrator having: a pair set on one end side The mounting portion of the movable portion, the column portion extending from the mounting portion, and the weight portion set at the free end, that is, the other end side, perform pendulum motion; the vibration source is applied to vibrate the vibrator to make the movable And the aforementioned basin along the circumference of the aforementioned basin The aforementioned objects have always been transported.

Here, as the object to be transported, for example, fine-sized electronic components (workpieces) can be cited, but there is no particular limitation as long as it can be transported by the linear feeder of the present invention.

According to the above-mentioned parts feeder of the present invention, when the vibrator is vibrated by the vibration source, the column part of the vibrator with the other end side of the weight part set as the free end will be installed in The mounting part of the movable part acts like a spring as a fulcrum, and the entire vibrator vibrates through a pendulum motion, and the reaction is used to vibrate the movable part, and the vibration is transmitted to the basin fixed at the upper end of the movable part. As a result, the basin vibrates, and the object to be conveyed placed on the basin can be conveyed.

In addition, in the present invention, the "ground" on which the fixed part is directly or indirectly fixed may of course be the ground on which a person walks, and also includes the concept of the placement surface of the platform where the parts feeder is placed.

As mentioned above, the parts feeder of the present invention adopts a new vibration principle that no one has thought about until now by using the vibration of the pendulum action of the vibrator to transport the objects to be transported on the basin, which can avoid ‧ Suppresses the deflection of the movable part and the fixed part, and even the deflection of the basin, which is inevitably generated in the structure of bending a pair of driving springs into an S-shape used in the conventional parts feeder, and can prevent ‧ restrain Stable conveying processing can be realized due to problems such as deviation of conveying speed due to deflection of the bowl.

If it is a conventional parts feeder where the twisting of the driving spring is the cause of the deflection of the bowl, high-precision processing of the movable part and the fixed part is required, and the parts feeder related to the present invention is combined will not There are special requirements, which is advantageous in this regard.

In addition, according to the parts feeder of the present invention, the column part is not deformed in an S-shape but in an arcuate shape among the vibrators that perform the pendulum motion, so it is different from the conventional driving spring that uses S-shape deformation. In contrast to the parts feeder, the displacement of the vibrator (the displacement of the column that acts like a spring) from the point of time before deformation to the point of maximum deformation can be much larger, and the vibration attenuation is also Less, the vibration amplification rate caused by resonance also becomes higher, and the efficiency can be improved.

Furthermore, in order to enable a more stable operation, it is preferable to provide a fixed part directly or indirectly fixed to the ground, and an anti-vibration spring that connects the fixed part and the movable part.

Moreover, in order to efficiently convert the pendulum vibration of the vibrator into horizontal rotational vibration suitable for the conveyance of the basin, it is preferable to provide a pair of vibrators in one group or in multiple groups, and each vibrator in each group is attached to the movable part It is fixed so that the extending direction of the column part is inclined in the opposite direction from the vertical direction. With this structure, the circular-arc vibration of the pendulum generates force at the parts facing each other and becomes twisted vibration. In addition, if the rigidity of the facing portion is higher, the deflection force that deflects the vibration-proof spring will not be transmitted to the bowl side, and stable vibration can be obtained.

Moreover, if the vibration source is a piezoelectric element, the pendulum vibration of the vibrator has an arcuate deformation structure, so compared with the conventional S-shaped deformation, a piezoelectric element with a larger area can be attached. , So the vibration force of each vibrator will become larger.

And of course, in order to realize the present invention with a simple structure Obviously, an electromagnet can also be used as a vibration source.

As described above, according to the present invention as described above, it is possible to provide a parts feeder that vibrates by a completely different vibration principle from the conventional parts feeder, and can convey objects to be conveyed efficiently and stably.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Regarding the pot-type feeder of the parts feeder of this embodiment, vibration is applied to the pot B that is substantially circular in plan view, and the conveyed objects (not shown) placed on the pot B are along the pot. Convey in the circumferential direction of B. As the object to be transported, extremely small-sized electronic components can be cited, but there is no particular limitation as long as it can be transported on the basin B by vibration.

Regarding the parts feeder of this embodiment, as shown in Figures 1 and 2 (Figure 1 is a front view of the parts feeder and Figure 2 is a side view), it is provided with: a fixing part 1; fixed at the upper end The movable part 2 of the basin B; the anti-vibration spring 3 connecting the fixed part 1 and the movable part 2; the mounting part 41 provided at one end is fixed to the movable part 2, and the predetermined position of the mounting part 41 is used as a fulcrum to perform pendulum movement The vibrator 4; and the vibrating source 5 that vibrates the vibrator 4, by operating the vibrating source 5 to vibrate the vibrator 4, so that the movable part 2 directly fixed to the vibrator 4 and fixed to the movable part The basin B of 2 vibrates to transport the objects.

The basin B is formed in a substantially circular grinding bowl shape in plan view. The bowl B1 is fixed to the movable portion 2 by a fixing screw N1 indicated by a dotted line at a central location in a plan view, and is supported to be vibrated, and the object to be conveyed is conveyed by controlling the vibration generated in the bowl B. The specific structure of the basin B can be applied to various types of existing shapes, and detailed descriptions are omitted.

The fixing part 1 is directly or indirectly fixed on the ground. In this embodiment, the fixing part 1 is constituted by the mounting block 11 fixed on the ground and the fixing pillar 12 erected from the mounting block 11. In this embodiment, the mounting block 11 is fixed by screws (not shown), for example. Set on the ground.

The movable portion 2 in the present embodiment is formed by fixing the pot B to the upper end integrally formed of, for example, a metal with high rigidity, and includes a movable portion body 20 that is in close contact with the bottom surface of the pot B, and the movable portion body 20 A hanging plate 21 hanging down from the center in the width direction. In this embodiment, screw holes 22 are provided on both sides of the hanging plate 21 in the width direction, respectively. The hanging plate 21 is arranged in a posture in which the plate thickness direction (thickness direction) coincides with the width direction. The space below the movable portion main body 20 on both sides of the hanging plate 21 is used as an arrangement space for the vibrator 4 described later.

One end of the anti-vibration spring 3 is fixed to the spring first attachment portion 1 a provided in the fixed portion 1, and the other end is fixed to the spring second attachment portion 2 a provided in the movable portion 2. The specific aspect of the anti-vibration spring 3 can be applied to various existing structures, and detailed descriptions and illustrations thereof are omitted.

Here, the basin-type feeder of this embodiment is characterized by having a mounting portion 41 for the movable portion 2 set at one end, a column portion 42 extending from the mounting portion 41, and a free end also That is, the weight portion 43 on the other end side is provided with a vibrator 4 that performs a pendulum movement, and a vibrator 4 for moving the movable portion 2 and the bowl B to convey the object along the circumferential direction of the bowl B. Add vibration source 5. Hereinafter, the vibrator 4 and the vibration source 5 will be described.

The vibrator 4, as shown in FIGS. 1, 2 and 4, includes: a mounting portion 41 provided on one end side and fixable to the movable portion 2, a column portion 42 extending from the mounting portion 41 in the height direction, The weight portion 43 is set at the free end, that is, on the other end side. That is, the vibrator 4, in this embodiment As an example, an integrally molded product of a material that can be elastically deformed according to its thickness has a mounting portion 41 formed at one end of the column portion 42 set to an elastically deformable thickness, and a weight portion 43 is formed at the other end.

In this embodiment, the mounting portion 41 of the vibrator 4 is fixed to the hanging plate 21 in the movable portion 2. The mounting part 41 has two screw holes 44 at both ends. Then, in a state where one surface of the mounting portion 41 is in contact with the hanging plate 21, the screw N2 inserted from the side is screwed into the screw hole 44 to fix the vibrator 4 to the movable portion 2. In this embodiment, the vibrators 4 paired on both sides are fixed to the movable portion 2 in a posture in which the thickness direction (thickness direction) and the width direction are aligned. The pair of vibrators 4 are fixed to the movable portion 2 so that the extending direction of the column portion 42 is inclined from the vertical direction to the opposite direction to each other.

The weight portion 43 is set on the free end of the vibrator 4, that is, on the other end side. In the present embodiment, the system is formed integrally with the column portion 42 and has a symmetrical shape around the column portion 42. Of course, the weight portion 43 may also have an asymmetrical shape around the column portion 42. In addition, the weight portion 43 and the column portion 42 may be configured separately. In addition, in this embodiment, the weight portion 43 has a shape that protrudes from the column portion 42 and extends toward the mounting portion 41. Therefore, a gap is formed between the weight portion 43 and the column portion 42, but of course the weight portion 43 The shape may be a shape extending only from the extending direction of the column portion 42 to the orthogonal direction, or a shape obtained by directly extending the column portion 42 so as to have no boundary with the column portion 42 in shape. .

Furthermore, regarding the pot feeder of this embodiment, it is set in the mounting portion 41, and the connection with the column portion 42 is used as a fulcrum. The vibrator 4 performs a pendulum movement. At this time, the column portion 42 of the vibrator 4 uses the elasticity of the material itself to function as a spring.

The pot-type feeder of this embodiment is constituted by a piezoelectric element 5 in which vibration sources 5 that vibrate the vibrator 4 are respectively provided on both sides of a column portion 42 having a plate shape.

In the present embodiment, the piezoelectric element 5 is applied to the area near the end of the column portion 42 and to cover most of the area as an example. Furthermore, each piezoelectric element 5 provided on the opposing surface of the column portion 42 is expanded and contracted (for example, a sine wave voltage is applied to the piezoelectric element 5 to generate periodic expansion), thereby causing the column portion 42 to interact with The connecting portion of the mounting portion 41 serves as a fulcrum to bend as a whole into an arch shape to perform a pendulum operation. As a result, the vibrator 4 adds the weight of the weight portion 43 to perform an appropriate pendulum operation, and the vibration of the vibrator 4 is generated. Here, the dimension along the thickness dimension of the column portion 42 is changed, whereby the vibration frequency can be easily changed. Moreover, even if the thickness dimension of the column portion 42 is set to be large to generate high-frequency vibration (for example, 1000 Hz to 2000 Hz), the mounting portion 41 of the vibrator 4 of the movable portion 2 is attached to the column portion 42 A screw hole 44 is provided at the staggered position of the connection part and fixed by the screw N2. Thereby, the large deflection of the column 42 during the movement of the pendulum can be well supported. In addition, since the column portion 42 flexes and deforms into an arch shape, the vibration attenuation is reduced, and the vibration amplification rate due to resonance is large, so the number of piezoelectric elements 5 necessary to obtain the desired amplitude can be reduced. The piezoelectric element 5 is fixed to the opposing surface of the column portion 42 by appropriate processing such as attaching processing. Between the piezoelectric element 5 and the weight portion 43, there is a predetermined Therefore, the interference between the piezoelectric element 5 and the weight portion 43 can be effectively avoided.

Regarding the pot feeder of this embodiment, when the vibrating source 5 is in the operating state (the ON state for expanding and contracting the piezoelectric element 5), the vibrator 4 performs a pendulum operation, and the movable portion is made by the reaction by vibration. 2 Vibration. This vibration is transmitted to the basin B and the basin B itself vibrates. Specifically, when at least any one of the vibrator 4 constitutes the piezoelectric element 5 constituting the vibration source 5 is expanded or contracted, the column portion 42 flexes and vibrates, and the entire vibrator 4 is fixed to the mounting portion 41 of the movable portion 2. The predetermined part (the part connected to the column part 42) is a fulcrum to perform a pendulum operation that reciprocates the free end side in an arc shape. In particular, since the weight portion 43 is provided on the free end side of the vibrator 4, the reaction force of vibration is large, and the vibrator 4 can perform the pendulum operation efficiently. Furthermore, among the two vibrators 4 that constitute a pair of vibrators 4, even if only the piezoelectric element 5 attached to one vibrator 4 is turned on, and the other vibrator 4 is When the attached piezoelectric element 5 is in the energized OFF state, the vibrator 4 of the piezoelectric element 5 with the energized OFF state will vibrate due to resonance.

In particular, regarding the basin B of the present embodiment, the vibrators 4 as described above are paired and arranged in a mutually inclined posture, so the vibrations of the paired vibrators 4 are combined. That is, if the pair of vibrators 4 are combined to be inclined to each other, a horizontal rotational vibration (twisted vibration) indicated by an arrow in the figure is generated by a force couple. In this embodiment, although the vibrator 4 is arranged to be inclined by 15°, the angle or rotation direction necessary for conveyance can be adjusted arbitrarily by appropriately determining the inclination angle. whole.

As described above, the basin-type feeder of the parts feeder of the present embodiment adopts a novel novel that no one has thought of until now that uses the vibration of the pendulum action of the vibrator 4 to convey the conveyed objects on the basin B The principle of vibration can avoid and suppress the deflection of the movable part 2 and the fixed part 1 that is inevitably generated in the structure of the previous parts feeder that is used to bend a pair of driving springs into an S shape. Even the deflection of the basin B can prevent and suppress the deviation of the conveying speed accompanying the deflection of the basin B, and realize stable conveying processing. In particular, the present embodiment does not conduct bending and deflection to the bowl B, so even if the bowl B is thin, stable operation can be realized. Furthermore, according to this structure, even if the strength of the basin B is the conventional level, high frequency vibration conveyance is possible. Specifically, by changing the vibration frequency of the vibrator 4, the vibration frequency of the driving part can be changed. In the structure of this embodiment, it can actually range from low frequency (around 100 Hz) to high frequency (for example, 1000 Hz to 2000 Hz), and can correspond to a wide range of objects to be conveyed.

In addition, in this embodiment, it is configured to include a fixed portion 1 that is directly or indirectly fixed to the ground and an anti-vibration spring 3 that connects the fixed portion 1 and the movable portion 2. In particular, in this embodiment, the arrangement of the anti-vibration spring 3 is configured to be close to the basin B, so unnecessary shaking called the floating of the basin B is actually extremely small.

Furthermore, in this embodiment, a pair of vibrators 4 are arranged such that the extending direction of the column portion 42 is inclined to each other from the vertical direction, whereby the circular arc vibration of the pendulum generates force at the positions facing each other. Become a twisting vibration. Thereby, the pendulum vibration efficiency of the vibrator 4 is good, and it can be converted into a horizontal rotation vibration suitable for the conveyance of the basin B.

Moreover, since the piezoelectric element 5 attached to the column 42 is applied as the vibration source 5, and the pendulum vibration of the vibrator 4 is a structure in which the pendulum is deformed, it can be attached in comparison with the conventional mode. The piezoelectric element 5 has a larger area, so the vibrating force of each vibrator 4 will increase. As a result, in the structure of the present embodiment, in reality, even if the piezoelectric element 5 is half the number of conventional piezoelectric elements, the same amplitude as the conventional one can be obtained. In other words, if the number of piezoelectric elements 5 is the same, the same effect can be obtained even if the current is about half. In addition, in view of the high efficiency of the vibrator 4, the total weight of the pot feeder can be reduced to about 1/2 compared with the prior art.

In addition, in this embodiment, as an example, it is disclosed that the mounting angle of the vibrator 4, that is, the inclination angle is set to 15°, but by changing the inclination of the vibrator 4, it is possible to easily change the basin which was difficult to perform in the past. B. Changes in vibration angle and rotation direction.
