BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating conveying apparatus, and more particularly, to a structure of a vibrating conveying apparatus suitable for conveying small electronic parts in large quantities.

Generally, in order to convey small components, such as an electronic component, various vibration conveyance apparatuses are used in a factory. In this type of vibratory conveying device, in recent years, high supply speed and supply accuracy have been required, and high speed and high performance have been urgently required. Moreover, since the mounting apparatus and other processing apparatus which require high precision are provided in the supply place of the above-mentioned electronic components, the problem that the operation of a processing apparatus is influenced by the vibration of a vibrating conveying apparatus is pointed out. For this reason, various proposals have been made in order to prevent the vibration generated in the vibrating conveying apparatus from being transmitted to the outside as much as possible.

As said proposal, although it is common to absorb a vibration through a rubber | gum and a spring through a base, there exist some structures with which the vibration energy which leaks to the outside in a vibrating conveying apparatus is suppressed. For example, the base and the carrier are elastically supported by a pair of elastic support springs, and one end of the excitation voltage element is connected to the carrier, and the other end is connected to the inertial body. The apparatus which made the conveyance body vibrate by the reaction of an inertial body is proposed (for example, refer patent documents 1 and 2 below).

In addition, a Y-shaped excitation body having two excitation portions on the base is connected, and a carrier is connected to one of the Y-shape excitation portions through an elastic support spring, and an inertial body (weight) is formed on the other excitation portion. Is also proposed to drive the two excitation parts in reverse phase (see, for example, Patent Document 3 below).

Moreover, the apparatus which supports the excitation body from the base in the state which has a point in the middle part, connects a carrier body to one point of an excitation body, and connects an inertial body (weight) to the other side of an excitation body point is proposed ( See, for example, Patent Document 4 below).

Moreover, the apparatus which connected one side of a carrier body and a vibrator with an elastic support, and connected the other side of a vibrator to an inertial body (weight), and interposed the elastic support body between this inertia body and a base once again is also known. (See Patent Documents 5, 6, 7, 8, and 9 below).

In each of the vibration conveying apparatuses, the inertial bodies (weights) connected to the excitation bodies have the advantage that the conveying bodies and the inertial bodies of the apparatus vibrate in reverse phase so that the vibration energy transmitted to the expectation can be controlled.

However, in each of the above-described apparatuses (Patent Documents 1, 2 and 4), the carrier is connected to the inertial body (weight) through the excitation body and is connected to the base through the elastic support separately from the carrier body. If the conveying characteristics are the same, there is a problem that the flow of vibration energy from the conveying body to the expectation cannot be sufficiently suppressed because it is very similar to a conventional device for directly oscillating the elastically supported conveying body.

In addition, in the above-described apparatuses (Patent Documents 3 and 4), it is not possible to reduce the outflow of vibration energy to the installation surface, but it is necessary to use a special structure and shape as the excitation body or support structure, so that the manufacturing cost increases. At the same time, there is a problem that it is difficult to flexibly cope with the situation and environment, such as adjusting the vibration characteristics and the like to the conveyed material.

In addition, in the above-described devices (Patent Documents 5, 6, 7, 8, and 9), the inertial body (weight) connected to the excitation body is supported by the elastic support on the base. The situation is basically the same as the case where it is placed on the installation surface, and since the outflow of vibration energy is mainly determined by the elastic characteristics of the elastic support between the inertial body and the base, it is possible to sufficiently reduce the vibration energy transmitted to the installation surface. There is a problem that can not be.

In view of this situation, the vibrating conveying apparatus of the present invention includes a base, a carrier disposed above the base, an oscillator for vibrating the carrier, and a carrier connected between the carrier and one portion of the carrier. An elastic support of 1, an inertial body connected to the other portion of the vibrator, and a second elastic support connected between the base and one portion of the vibrator and between the base and the first elastic support It is characterized by.

According to the present invention, the vibrator does not vibrate the carrier body directly or indefinitely, but generates vibration between the connection portion between the first elastic support member and the second elastic support member and the inertial body. Compared with a conveying apparatus, it was confirmed that the vibration state of a conveying body became the direction exactly along a conveying direction, the coarse movement of the conveying body was also reduced, and conveyance efficiency improved. Moreover, since the excitation body connected to the inertia body is connected between the carrier body and the base at the back, the reaction from the carrier body is less likely to be transmitted to the base, so that the vibration energy flowing out to the outside is reduced.

For example, in the experimenter started by the inventors, the excitation body generates a vibration between the connection point and the inertial body of the first elastic support and the second elastic support, and vibrates the connection point and the inertial body in reverse phase with each other. The vibration of the connection point is transmitted to the carrier through the first elastic support, thereby realizing a predetermined conveyance state. At this time, the carrier vibrates inversely with the inertial body. Since the base is connected to the vibrator and the first elastic support through the second elastic support, the inertial body connected to the vibrating body vibrating in reverse phase and the carrier connected to the first elastic support are affected together. As a result, the vibration energy received by the expectation is reduced, and the vibration energy flowing out to the outside is reduced.

Moreover, in the said invention, since it does not require what has a special and complicated shape and structure as an excitation body, an inertial body, a 1st elastic support body, and a 2nd elastic support body, manufacturing cost can be reduced. In addition, since the exciter body is connected to the carrier and the base via the first elastic support and the second elastic support, respectively, vibrations to the outside through the transfer characteristics and the base of the carrier are adjusted by adjusting the elastic characteristics of the elastic support. The outflow characteristic of energy can be easily adjusted.

In the present invention, the vibrator, the first elastic support and the second elastic support are respectively provided at two positions separated from each other in the conveyance direction of the conveying body, and the inertial body before and after is connected to the common inertial body. It is preferable to be connected together. According to this, a conveyance body is elastically supported by two places separated in the conveyance direction, respectively, and conveyance performance can be improved by connecting these two places to each excitation body. In addition, since the two vibrating bodies corresponding to the two locations are connected to a common inertial body, a single vibration system (common system) can be configured to stabilize the vibration characteristics, and also increase the rigidity of the vibration system. Durability can be improved and the whole apparatus can be made compact.

In the present invention, the first elastic support and the second elastic support are preferably plate-shaped elastic bodies disposed along a common straight line. According to this, since the 1st elastic support body and the 2nd elastic support body which consist of a plate-shaped elastic body are arrange | positioned along one straight line, unnecessary vibration components other than the vibration of the echo required for conveyance can be reduced, and a conveyance body is the said Since the vibration characteristics are similar to those supported by one plate-like elastic body along a straight line, setting and adjustment of the conveying characteristics of the conveying body are facilitated.

In the present invention, the vibrating body is preferably in a form in which the other part is disposed above the one part. Since the inertia body can be disposed in a position close to the carrier body by placing the other part above the one part of the excitation body, generation of unnecessary vibration modes other than the vibration components necessary for conveyance can be suppressed and this unnecessary vibration It is possible to suppress an increase in vibration energy flowing out to the expected side by the mode. In addition, since the inertial body can be disposed in a position close to the carrier body, generation of unnecessary vibration modes can be suppressed, which also has the advantage that the mass and volume of the inertial body can be increased.

In the present invention, it is preferable that the inertial body is disposed at a height range overlapping with the vibrating body. According to this, since the inertial body is arrange | positioned in the height range which overlaps with an excitation body, since an inertial body and an exciting body can be comprised compactly in the up-down direction, it becomes possible to reduce the height of an apparatus, ensuring a predetermined performance.

It is preferable to have a 3rd elastic support body connected to the said inertial body in this invention, and a 2nd conveyance body connected to this 3rd elastic support body. According to this, since the vibration of an inertial body is transmitted to a 2nd conveyance body through a 3rd elastic support body, it becomes possible to convey a conveyed object also by 2nd conveyance.

In this invention, it is preferable that the said 2nd conveyance body is provided in the said conveyance body, and is comprised so that it may receive the conveyed material excluded from the said conveyance body, and conveys it in the reverse direction to the conveyance direction of the said conveyance body. According to this, since a 2nd conveyance body is provided in a conveyance body, and is comprised so that a conveyance thing excluded from the conveyance body may be received and conveyed in a reverse direction, it is conveyed by an inadequate conveyed material (for example, conveyed in a bad form) The conveyed article, or the conveyed article itself is a defective article, etc.) can be recovered. In particular, by constituting a circulation path for returning the conveyed material recovered by the second carrier to the carrier, efficient conveyance of the conveyed material becomes possible.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with an illustration example. 1: is a schematic side view of this embodiment, FIG. 2 (A) is a schematic front view of this embodiment, and FIG. 2 (B) is a schematic plan view which abbreviate | omitted and showed the conveyance material of this embodiment.

The vibratory conveyance apparatus 10 of this embodiment is a base 1, the carrier 2 arrange | positioned above this base 1, the excitation body 3 for vibrating the carrier 2, , The first elastic support 5 connected between the connecting member 4 connected to one portion (lower end) of the excitation body 3, the carrier 2 and the connecting member 4, and the excitation body ( It has the inertial body 6 connected to the other part (upper part) of 3) and comprised as the free end, and the 2nd elastic support body 7 connected between the connection member 4 and the base 1. As shown in FIG.

The base 1 is provided with the support plate 1A arrange | positioned on an installation surface, and the attachment plate 1B fixed on this support plate 1A, and the said 2nd elastic support body 7 fixed through a bolt etc. have.

The conveying body 2 has the attaching material 2A to which the said 1st elastic support 5 was fixed through the bolt etc., and the conveying material 2B fixed on this attaching material 2A, and the conveying material 2B Not shown)

A track on the image is formed. The track extends in the left and right directions of FIG. 1 and supports the component (not shown) while the component is referred to by the vibrating body S3, which is transmitted from the excitation body 3 to be described later. Is referred to as " F ".

The exciter 3 is made of, for example, a piezoelectric element. Specifically, the piezoelectric elements are bimorph piezoelectric elements configured to be formed by forming piezoelectric layers on both front and rear surfaces of the elastic plate and applying predetermined piezoelectric to these piezoelectric layers. Of course, it is also possible to use a unimorph piezoelectric element in which a piezoelectric layer is formed only on the plate surface of the elastic plate. These piezoelectric elements are bent and vibrated at this frequency by supplying AC power of a predetermined frequency from the outside.

In this embodiment, the set of the said carrier 3, the connection member 4, the 1st elastic support 5, and the 2nd elastic support 7 is respectively provided in front and back two places separated by the conveyance direction F, respectively. It is. That is, the carrier body 2 is elastically supported by the 1st elastic support body 5 and the 2nd elastic support body 7 in front and back at two places.

Moreover, the exciting body 3 arrange | positioned at the front side is arrange | positioned at the back of the 1st elastic support body 5 of the front side, and is connected to the inertial body 6 arrange | positioned at the rear, and the excited body 3 arrange | positioned at the rear side. ) Is disposed in front of the first elastic support 5 on the rear side and is connected to the inertial body 6 disposed on the front side. That is, the inertial body 6 is arrange | positioned in the middle of the front-back direction of the two pairs of excited bodies 3, and the two paired excited bodies 3 are connected together to the common inertial body 6 together.

The inertial body 6 has an inertial plate 6A connected to the exciter 3 and an inertial block 6b fixed to the inertial plate 6A, and the lower part of the inertial plate 6A disposed above. The inertial block 6B is suspended from the structure. The inertial plate 6A is disposed adjacent immediately below the carrier 2, and the inertial block 6B is installed to protrude downward from the inertial plate 6A so as to overlap in the same height range as the excitation body 3. have.

The first elastic support 5 and the second elastic support 7 together are a plate-like elastic body, for example a leaf spring. The first elastic support 5 and the second elastic support 7 are arranged along a common straight line as viewed from the side. Accordingly, both elastic support members have similar support characteristics as the case where a single plate-like elastic body is formed between the base 1 and the carrier 2. That is, when the first elastic support 5 and the second elastic support 7 are provided at positions out of the front-rear direction, the direction different from the original vibration direction S1 orthogonal to the shape of the excitation body 3 is provided. Unnecessary vibration mode (for example, vibration mode oscillating in the up and down direction) is generated, and the elastic support 5 on both sides as described above may be adversely affected on the conveyance characteristics of the carrier 2. By placing 7 along a common straight line, it is possible to control the generation of unnecessary vibration modes.

Moreover, said common straight line is comprised so that it may become parallel to the extension direction of the excitation body 3. As shown in FIG. Thereby, the bending vibration of the direction orthogonal to the extending direction (direction along the plate surface) of the excitation body 3 can be transmitted to the 1st elastic support body 5 efficiently, and the conveyance body 2 can be vibrated efficiently. . In this embodiment, as shown by the arrow shown with respect to the conveyance body 2, the non-shown part on the conveyance body 2 is conveyed by giving the vibration S3 of the direction inclined a little up-down with respect to the horizontal direction. It is comprised so that conveyance along the direction F may be carried out. Therefore, in order to transmit such vibration efficiently, the excitation body 3 extends in the direction slightly inclined in the front-rear direction with respect to the vertical direction, and furthermore, the 1st elastic support 5 and the 2nd elastic support ( 7) is made to extend in the direction parallel to this.

In addition, the lower end of the excitation body 3 is connected to the connecting portion 4, and the upper end of the excitation body 3 is connected to the inertial body 6, thereby easily integrating the inertial body 6 to the carrier 2 Since it can approach, the moment generate | occur | produced by the conveying body 2 and the inertial body 6 which vibrate mutually in reverse phase can be reduced, and unnecessary vibration mode can be suppressed. Moreover, since the inertial body 6 (especially the inertial block 6B) is arrange | positioned so that it may overlap in the height range of the excitation body 3, even if the mass and the volume of the inertial body 6 are enlarged, the apparatus 1 will be raised in the height direction. It can be configured compactly.

In the device 10 configured as described above, when the DC power is supplied to the vibrating body 3 and the bending vibration occurs, the connecting member 4 and the inertial body 6 are excited on both sides of the vibrating body 3. Vibrate in the bending direction. The vibration S1 of the connecting member 4 is amplified by the first elastic support 5 and the second elastic support 7 with the base 1 as the point, and the vibration S3 in the carrier 2. ). In addition, the free end of the inertial body (6) generates a vibration (S2) having a vibration phase reverse to the connecting member (4).

In this embodiment, unlike the conventional vibrating conveying apparatus, one end of the excitation body 3 is connected together to the first elastic support 5 and the second elastic support 7, and the excitation body 3 is provided. Since the other end of is connected to the inertial body 6, one end of the excitation body 3 does not have a structure which vibrates the carrier 2 directly and indefinitely, and thus the vibration of the carrier 2 (S3). ) Occurred correctly along the conveying direction F, and it was confirmed that coarse movement in the vertical direction was also reduced. That is, when shooting with high-speed video or the like, in the conventional conveying apparatus, the conveyance attitude of the parts is disturbed from side to side, the upper and lower parts move severely, or the parts sometimes move in the reverse direction. This was to be conveyed correctly in the conveying direction regularly. As a result, it was confirmed that the vibration energy was efficiently transmitted to the parts, the conveyance direction F of the parts was easily matched, and the conveyance speed was improved.

In addition, the base 2 is connected to the connecting member 4 via the second elastic support 7, and the carrier 2 is connected to the connecting member 4 via the first elastic support 5. At the same time, since the inertial body 6 is connected through the excitation body 3, the vibration elements vibrating in reverse phase with each other are connected together, and as a result, the vibration energy transmitted to the base 2 can be reduced. Therefore, it is possible to reduce the adverse effect of the vibration on the adjacent device and to suppress the noise.

Moreover, in this embodiment, since it is not necessary to use what has a special and complicated shape or structure as the excitation body 3, the 1st elastic support body 5, and the 2nd elastic support body 7, manufacturing cost can be reduced. In the example of illustration, the excitation body 3, the 1st elastic support body 5, and the 2nd elastic support body 7 are comprised by plate-shaped object.

FIG. 3 is a side view showing the conveying material of the vibrating conveying apparatus 10 'different from the above, and FIG. 4 is a front view of the vibrating conveying apparatus 10'. Since this conveying apparatus 10 'has a structural part common to each component of said embodiment, the same code | symbol is attached | subjected about each component of a common structural part, and description of the same content is abbreviate | omitted.

In this apparatus 10 ', the columnar support body 8 is fixed to the inertial body 6, and the 3rd elastic support body 9 is connected to this support body 8. The third elastic support 9 is connected between the support 8 and the second carrier 11. The 2nd conveyance body 11 has the attachment material 11A connected to the 3rd elastic support body 9, and the conveyance material 11B fixed on this attachment material 11A. The third elastic support 9 is attached in a form inclined in the opposite direction to the first elastic support 5. In the present embodiment, two third elastic supports 9 are provided, and the lower ends of these two elastic supports 9 are connected to two portions positioned before and after the support 8, respectively, and two elastic supports are provided. The upper end of (9) is connected to the site | part before and behind the said 2nd conveyance body 11, respectively. The inclination angles of the two third elastic supports 9 may be set such that the front and rear sides are at substantially the same angle (ie, the front and rear elastic supports are parallel) as shown, but for example, so as to have different angles from front to back. It can be set.

The 2nd conveyance body 11 is arrange | positioned in parallel with the said conveyance body 2, and is arrange | positioned in the side of the conveyance body 2 in parallel with the conveyance direction F of the conveyance body 2. And the track which is not shown on the 2nd carrier 11 is arrange | positioned slightly below the track which is not shown on the carrier 2. The track on the second carrier 11 may be parallel to the track on the carrier 2 or may be non-parallel. In addition, each track may be horizontal, and may be a slope up or a slope down along a conveyance direction. The second carrier 11 vibrates through the third elastic support 9 according to the vibration S2 ′ of the inertial body 6, and vibrates by the inclination of the third elastic support 9 (S3). ), The components not shown are conveyed in the conveyance direction B opposite to the conveyance direction F by the vibration S4 of the direction inclined in the reverse direction.

In addition, in this embodiment, the excitation body 3 is attached in a substantially perpendicular form between the connecting member 4 and the inertial body 6. This is because the vibration S2 ′ of the inertial body 6 caused by the excitation body 3 is substantially leveled, thereby causing the vibration S4 of the second carrier 11 vibrating through the third elastic support 9. When the direction is inclined approximately, the angle difference between the vibration S2 'of the inertial body 6 and the vibration S4 of the second carrier 11 and the vibration S1 of the connecting member 4 And an unbalance in the angle difference between the vibration S3 of the carrier body 2. In this embodiment, the 1st elastic support body 5 and the 3rd elastic support body 9 have the inclination-angle which is substantially symmetrical with respect to a vertical direction (extension direction of the vibration body 3).

In addition, the vibrating conveying apparatus of this invention is not limited only to the above-mentioned illustration, Of course, various changes can be added within the range which does not deviate from the summary of this invention. For example, the above embodiment shows a case in which the component is configured as a linear feeder for conveying the parts linearly. However, even in a ball feeder for conveying the parts in a spiral shape, the vibrational direction is changed from the front-rear direction to the spiral track. It can be applied easily by changing the rotation direction around the axis. In addition, the first elastic support and the second elastic support may be constituted by an integral elastic member, and the connecting member or the excitation body may be connected to an appropriate portion of the elastic member.

This invention solves the said problem, The subject is the vibration conveyance apparatus which can adjust a conveyance characteristic easily, the excitation body which has a special shape and structure is unnecessary, and can suppress the outflow of vibration energy to the outside. Is to provide.
