However, in the case of the above-described patent documents and the like, the movable table on which the object to be transported is supported by the central portion of the leaf spring that is fixed only at both ends, it is difficult to avoid the rotation of the movable table. That is, swinging. Moreover, in order to avoid the swing, it is necessary to have a weight of a certain weight or more, and as a result, the total weight of the entire apparatus becomes heavy.

Further, the leaf springs that vibrate in the respective directions are indirectly coupled to each other, so that the springs are deformed to each other, and it can be referred to as a structure that easily causes unnecessary vibration.

Further, due to the specifications of the movable table, the resonance frequencies of the respective directions are different. Therefore, when the movable table is exchanged, the spring constant corresponding to the new specification is individually set for each direction.

The present invention has been made in view of the above-described viewpoints, and a main object thereof is to provide an article transporting apparatus that realizes vibration by a vibration principle that is completely different from that of a conventional article transporting apparatus, and in particular, can be transported accurately and stably. Things.

The present invention has been made in view of the above problems, and the following means are employed.

In other words, the article conveying device of the present invention includes: a fixing portion, a movable table that is elastically supported with respect to the fixing portion, and a first vibration absorbing means that vibrates the movable table in a horizontal first direction, and the movable table The second vibration absorbing means that vibrates in the second direction that intersects the first direction in the horizontal direction and the third vibration absorbing means that vibrates the third direction in the vertical direction of the movable table are placed by the vibration of the movable table The first, second, and third vibration absorbing means are provided with a vibrating member that is directly or indirectly mounted to the movable table set on one end side. a portion, a column portion extending from the mounting portion, and a weight portion set at the free end, that is, the other end side, and performing a pendulum motion; and a vibration source for vibrating the vibrating member to transport the movable table Carrying goods.

According to the above invention, only the linear vibration is transmitted to the respective portions by the pendulum movement of the vibrating member, and the bay curve or the deflection at the mounting position of the mounting portion is minimized, and stable vibration can be obtained. Moreover, the vibration can be easily changed by changing the thickness of each part constituting the vibrating piece or the mass of the weight portion. frequency. Further, the effective length for performing the pendulum motion is changed by the movement of the mounting position of the weight portion, whereby the vibration frequency can be easily changed. In other words, according to the present invention, it is possible to provide an article conveying device that can realize vibration in a completely different vibration principle from the conventional article conveying device, and in particular, can convey the object to be conveyed accurately and stably.

In order to more reliably transmit the vibration of the vibrating member to the movable table, it is preferable to arrange the plurality of vibrating members side by side in the first direction or the second direction. Further, if this structure is applied, even if only one of the plurality of vibrating members provided is vibrated, the other vibrating members that are not vibrated will vibrate by resonance, so that they can be transported.

Further, in order to more reliably transmit the pendulum motion of the vibrating member to the movable table, the movable portion is fixed to the movable table to mount the vibrating member, and the movable portion is formed between the fixed portion and the movable table. The internal space accommodates the vibrating member. In this configuration, it is not necessary to obtain the weight for balancing in order to prevent unnecessary vibration such as swinging, rolling, and shaking from occurring, and in fact, the overall mass can be about 1/4 to 1/5 as compared with the conventional model.

In order to easily design such that the position of the center of gravity of the vibrating member coincides with the position of the center of gravity of the entire article transporting device, it is preferable that the first, second, and third vibrating means are independently attached to the movable portion. In this way, each of the vibrating members constituting the first, second, and third vibrating means is set at an arbitrary position, and the center of gravity of the vibrating member is designed to match the position of the center of gravity of the entire article transporting device. The occurrence of the rotational moment is extremely small, and as a result, a stable constant vibration can be obtained in the entire movable table.

In order to effectively increase the oscillating force of each of the vibrating members, the oscillating source is preferably a piezoelectric element. In other words, the vibrating member can be formed into a substantially arcuate shape. Therefore, the piezoelectric element having a large area can be used to increase the vibrational force per vibrating member.

As described above, according to the present invention described above, it is possible to realize vibrations that are completely different from the conventional article conveying device, and in particular, the article conveying device that can convey the object to be conveyed accurately and stably.

The movable table T is fixed and supported by the upper surface side 2 of the movable portion 2 to be oscillated, and the object to be conveyed is conveyed by controlling the vibration generated by the movable table T. The specific configuration of the movable table T can be applied to various types of the present invention, and a detailed description will be omitted.

The movable portion 2 is supported by the vibration-proof spring 3 and the movable table T is placed and fixed on the upper side. In the present embodiment, the first vibration absorbing means X that oscillates the movable table T in the horizontal first direction and the first horizontal direction intersect with the first direction are separately assembled in the movable portion 2 The second vibration absorbing means Y that vibrates in the two directions and the third vibration absorbing means Z that vibrates the movable table T in the third direction perpendicular to the vertical direction. In the present specification, the first direction is defined as the horizontal direction in the plan view of each of the drawings, and the second direction is defined as the vertical direction.

Here, the article conveying device according to the present embodiment is characterized in that the first, second, and third vibration absorbing means X, Y, and Z are provided with the following members: the vibrating member 4 having: a mounting portion 41 that is directly or indirectly attached to the movable table T on one end side, a column portion 42 that extends from the mounting portion 41, and a weight portion 43 that is disposed at the other end side of the free end, and performs a pendulum motion; The vibration source 5, that is, the piezoelectric element 5, vibrates the vibrating member 4 to transport the object to be transported by the movable table T.

Hereinafter, the movable portion 2 and the first, second, and third vibrations are applied. The means X, Y, and Z, in particular, the structures of the vibrating member 4 and the piezoelectric element 5 provided in the first, second, and third vibrating means X, Y, and Z are specifically described.

In the present embodiment, the movable portion 2 is integrally formed of a metal having high rigidity, and the movable table T is fixed to the upper end portion, and includes a ring having a substantially rectangular shape in a plan view in close contact with the bottom surface of the movable table T. The frame 21 and the lateral frame portion 22 which are crossed on the inner side of the annular frame 21 so as to intersect each other in the vertical direction. In the present embodiment, as shown in FIG. 2, the first mounting portion 2x to which the first vibration applying means X can be attached is formed by bulging the both sides of the annular frame 21 in the width direction. Further, the second mounting portion 2y to which the second vibration isolating means Y can be attached is formed by bulging the center of both sides of the annular frame 21 in the up-down direction. Then, as shown in FIGS. 2 and 3, a third mounting portion 2z to which the third vibration isolating means Z can be attached is formed on the lower center side of the horizontal frame portion 22. In the third attachment portion 2z, the two vibrators 4 arranged in the horizontal direction of the column portion 42 are arranged to intersect orthogonally at the position of the attachment portion 41. In the present embodiment, the space in which the fixed portion 1 and the movable table T are overlapped in the plan view is used as the internal space S, and is used as an arrangement space of the vibrator 4 to be described later.

Hereinafter, the vibrating member 4 and the vibrating source provided in the first, second, and third vibrating means X, Y, and Z will be described.

As shown in FIG. 1 , FIG. 2 , and particularly as shown in FIG. 4 , the vibrating member 4 includes a mounting portion 41 that is fixed to the movable portion 2 at the center in the longitudinal direction, and a column portion 42 that extends from the mounting portion 41 . The weight portion 43 at the free end, that is, both end sides is set. That is, the vibrating member 4 is in this embodiment As an example, the column portion 42 which is elastically deformable is mainly composed of a mounting portion 41 at the center portion of the column portion 42 which is set to be elastically deformable, and a screw n2 for the other end portion. The weight portion 43 is assembled.

In the present embodiment, the vibrating member 4 is fixed to the first mounting portion 2x, the second mounting portion 2y, and the third mounting portion 2z in the movable portion 2 by the four mounting screws n1. Part 41.

The weight portion 43 is assembled to the column portion 42 by using a weight of a weight on the both ends of the vibrating member 4, that is, both ends. In the present embodiment, the weight portion 43 and the column portion 42 are formed separately, and the column portion 42 has a symmetrical shape. However, the weight portion 43 may be an asymmetrical shape in the column portion 42. Further, the weight portion 43 may be formed integrally with the column portion 42. Further, in the present embodiment, the weight portion 43 is formed to be swelled from the column portion 42 and extends toward the attachment portion 41 side. Therefore, a gap is formed between the weight portion 43 and the column portion 42, but the weight portion 43 is of course The shape may be a shape that extends only in the direction orthogonal to the direction in which the column portion 42 extends, or a shape in which the column portion 42 is directly extended, and the column portion 42 has no boundary with respect to the shape. .

Further, the article conveying device according to the present embodiment is configured such that the vibrating member 4 is oscillated in the attachment portion 41 with the connection with the column portion 42 as a fulcrum. At this time, the column portion 42 of the vibrating member 4 functions as a spring by utilizing the elasticity of the material itself.

The article transport device according to the present embodiment is configured to vibrate The vibration source 5 that vibrates the movable member 4 is constituted by the piezoelectric element 5 which is provided on both surfaces of the plate-shaped column portion 42.

In the present embodiment, the piezoelectric element 5 is applied to a region in the vicinity of the end portion of the column portion 42 to cover the size of the large half portion. Further, the piezoelectric element 5 provided on each of the opposing faces of the column portion 42 is expanded and contracted (for example, a sinusoidal voltage is applied to the piezoelectric element 5 to generate a periodic extension), whereby the column portion 42 is mounted and mounted. The portion where the portion 41 is connected is a fulcrum, and is integrally bent into an arch shape to perform a pendulum motion. As a result, the vibrating member 4 is subjected to an appropriate pendulum operation by adding the weight of the weight portion 43, and the vibration of the vibrating member 4 is generated. Here, the size along the thickness dimension of the column portion 42 is changed, whereby the vibration frequency can be easily changed. Further, even if the thickness 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 vibrating member 4 with respect to the movable portion 2 is attached by the screw n1. Come securely. Thereby, the large deflection of the column portion 42 during the pendulum motion can be favorably supported. Further, since the column portion 42 is deformed into a bow shape, the vibration attenuation is reduced, and the vibration increase rate due to resonance is large, so that the number of piezoelectric elements 5 necessary for obtaining a desired amplitude can be reduced. The piezoelectric element 5 is fixed to the opposing surface of the column portion 42 by, for example, an appropriate process such as a bonding process. Between the piezoelectric element 5 and the weight portion 43, as described above, a predetermined gap is secured, so that the piezoelectric element 5 and the weight portion 43 can be effectively prevented from interfering with each other.

In the article conveying device of the present embodiment, when the vibration source 5 is in an operating state (an ON state in which the piezoelectric element 5 is expanded and contracted), The vibrating member 4 performs a pendulum motion, and the movable portion 2 is vibrated by the reaction by vibration, and the vibration is transmitted to the movable table T to vibrate the movable table T itself. Specifically, when the piezoelectric element 5 constituting the vibration source 5 of at least one of the vibrators 4 is expanded and contracted, the column portion 42 is flexed and vibrated, and the entire vibrating member 4 is fixed to the mounting portion 41 of the movable portion 2. The predetermined portion (the portion connected to the column portion 42) is a fulcrum, and a pendulum motion for reciprocating the free end side in an arc shape is performed. In particular, since the weight portion 43 is provided on the free end side of the vibrating member 4, the reaction force of the vibration is large, and the vibrating member 4 can perform the pendulum operation efficiently. Among the two vibrators 4 constituting the pair of vibrators 4, even the piezoelectric element 5 attached to only one of the vibrators 4 is turned on, and the other vibrator 4 is placed. The attached piezoelectric element 5 is in an energized OFF state, and the vibrator 4 of the piezoelectric element 5 with the energized OFF state also vibrates due to resonance.

In the article transporting device of the present embodiment, the first vibration applying means X and the second vibration absorbing means Y have the action points of the force applied by the vibrating member 4 dispersed in two places, so that it is difficult to oscillate. Unnecessary vibrations such as rolling, shaking, etc.

As described above, in the article conveying device of the present embodiment, only the linear vibration is transmitted to the respective portions by the pendulum movement of the vibrating member 4, so that the bay curve or the deflection of the attachment position of the attachment portion 41 is minimized. Stable vibration. Further, the vibration frequency can be easily changed by changing the thickness of each of the vibrating members 4 or the mass of the weight portion 43 and adding it. Further, the pendulum is changed by the movement of the mounting position of the weight portion 43 The effective length of the movement, whereby the vibration frequency can be easily changed. In other words, according to the present embodiment, it is possible to realize vibrations that are completely different from the conventional article conveying device, and in particular, the article conveying device that can convey the object to be conveyed accurately and stably.

In order to more reliably transmit the vibration of the vibrating member 4 to the movable table T, it is preferable that the plurality of vibrators 4 are arranged side by side in the first direction or the second direction. Further, if this structure is applied, even if only one of the plurality of vibrating members 4 provided is vibrated, the other vibrating members 4 that are not oscillated will vibrate by resonance, so that they can be transported.

Further, in the present embodiment, the movable portion 2 is fixed to the movable table T to mount the vibrator 4, and the movable portion 2 is configured to accommodate the vibrating member 4 in the internal space formed between the fixed portion 1 and the movable table T. Thereby, the pendulum motion of the vibrating member 4 can be more reliably transmitted to the movable table T. Specifically, in this configuration, it is not necessary to make the balance vibration, such as swinging, rolling, and shaking, difficult to occur in order to achieve balance, and in fact, the overall mass can be 1/4 to 1/1 compared with the conventional model. 5 or so.

Further, in the present embodiment, the first, second, and third vibration absorbing means X, Y, and Z are independently attached to the movable portion 2, whereby the center of gravity of the vibrating member 4 and the article transporting device are easily designed. The position of the center of gravity of the vibrating members 4 constituting the first, second, and third vibration absorbing means X, Y, and Z is designed to match the position of the center of gravity of the entire article transporting device to cause the occurrence of the rotational moment. As a result, it is possible to achieve a constant vibration that is stable throughout the movable table T.

Further, in the present embodiment, the vibration source is a piezoelectric element, and the oscillating force of each of the vibrators 4 is effectively increased. In other words, the vibrating member 4 can be formed into a substantially arcuate shape. Therefore, the piezoelectric element 5 having a large area can be used to increase the vibrational force per vibrating member 4.

In particular, in the present embodiment, the same vibrating members 4 are used for all of the vibrating means X, Y, and Z. In this way, even if the mass of the movable table T changes, the values of "mass versus spring constant" in each direction can be made the same. Therefore, the resonant frequency changes in the same direction in all directions. As a result, it is not necessary to adjust the resonance frequency. Further, in the case of the present embodiment, the fluctuation of the resonance frequency due to the change in the weight of the movable table T is actually extremely small as compared with the related art. Therefore, it can be said that it is substantially unnecessary to adjust the resonance frequency.

Further, in the present embodiment, the column portion 42 of the vibrator 4 has an arcuate deformation and a small vibration attenuation, and the vibration amplification rate due to resonance is large. Therefore, even if the piezoelectric element 5 is one of the conventional ones, actually It is also possible to obtain the same amplitude as in the past. In other words, if the piezoelectric element 5 has the same number of sheets, the current required will become about half.
