Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating conveying apparatus, and more particularly to a conveying mechanism of a conveying apparatus which is suitable for conveying a component in a linear shape.
Generally, a vibrating-type conveying device is a device in which a conveying body is elastically supported by a plate spring on a base, and the conveying body is excited by an exciting means such as an electromagnetic drive unit or a piezoelectric drive unit, So that the conveyed object such as a part is conveyed along the conveying path formed on the conveying body. 2. Description of the Related Art In recent years, there has been an increase in the number of fine electronic parts as a transported material and a demand for supplying such fine transported materials at high speed. Therefore, a device for transporting fine transported materials at high speed is required Is coming. A common problem of the oscillating conveying apparatuses which are generated when the demand for high-speed conveyance is met is that a reaction force of vibration of the conveying body is transmitted to the installation surface, And the conveying body vibrates in a direction different from the original vibration direction by a pitching operation or the like of the whole vibrating structure for vibrating the conveying body so that the conveying speed changes depending on the position in the conveying direction, And the conveying posture is disturbed.
In order to solve the above problems, one of the methods proposed in the conventional vibratory transfer apparatus is to support a vibration system via a vibration-proof spring and to provide a reaction weight (an inertial body) vibrating in a reverse phase to the carrying body, And the reaction force of the vibration of the carrier is canceled by the vibration of the reaction weight to reduce the vibration energy transmitted on the mounting surface (for example, Patent Document 1 below). However, in such a structure, since the center of the conveying body and the reaction weight are shifted up and down, a pitching motion is generated in the entire apparatus accompanied by the oscillation of the conveying body, thereby lowering the conveying efficiency, The conveying speed is changed or the conveying posture is disturbed. Therefore, it is known that the pitch between the center of the conveying body and the center of the counterweight is reduced to suppress the pitching. For example, a structure in which a balancing weight disposed below a reaction weight is connected to a carrier is proposed (for example,
However, in the vibratory transfer apparatus provided with the conventional counteracting weight, since the structure is complicated in order to approximate the center of the conveying body and the center of the counteracting weight or arrange them in a straight line, the size of the apparatus and the manufacturing cost are increased And at the same time, it is necessary to set the center position extremely precisely. Therefore, there is a problem that it is difficult to obtain a sufficient effect at the manufacturing site where the conditions such as the kind of conveyed article and the conveying speed change. Particularly, even if there is a slight shift in the center position, if the driving frequency is increased to enable high-speed transportation, pitching, vertical movement and the like become serious and proper transporting state can not be obtained. .
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a vibration type conveying apparatus which can easily realize high- It is on.
In view of such a situation, the vibrating-type conveying apparatus of the present invention comprises: a pair of vibration-proof springs provided at front and rear positions in the conveying direction, each pair being composed of a leaf spring having a plate surface facing the conveying direction; A lower mass located below the reference mass, and a lower mass located below the reference mass, wherein the reference mass and the upper mass are arranged in the conveying direction A pair of upper vibration springs each including a plate spring structure having a plate surface facing the carrying direction which is elastically connected to each of the front and rear positions, and a pair of upper and lower vibrating springs which elastically connect the reference mass and the lower mass body respectively at front and rear positions in the carrying direction A pair of lower vibration springs including a plate spring portion facing the carrying direction, And an in-phase excitation means for applying a bi-directional force between the reference mass and the lower mass and for causing a vibration on the same phase in the transport direction to occur between the upper mass and the upper mass, Wherein the upper oscillating spring and the lower oscillating spring have an oscillating angle that is inclined to the opposite side in the up-and-down direction, and wherein the oscillating angle of the upper oscillating spring and the lower oscillating spring , And the upper mass and the lower mass vibrate in an inclined direction opposite to the upper and lower directions.
According to the present invention, the upper mass body and the lower mass body are resiliently connected to each other on the upper and lower sides of the reference mass supported by the vibration springs at the front and rear positions in the carrying direction via vibration springs at front and rear positions in the carrying direction, The upper and lower masses oscillate in the same phase as viewed in the transport direction, and the reference mass, the upper mass and the lower mass move in opposite phases in the transport direction. Therefore, it is possible to reduce the offset between the center position of the reference mass and the vertical position of the center position of the upper mass body and the lower mass body, so that the canceling action of the reaction force of the vibration in the carrying direction of the reference mass, have. Further, at the same time, since the rotational moment imparted by the upper mass and the rotational moment imparted by the lower mass with respect to the reference mass are opposite to each other, the reaction force in the rotational direction due to the vibration received by the reference mass is mutually canceled or attenuated , The pitching operation (rotational motion) can be suppressed. Therefore, the reaction force in the conveying direction and the vertical direction transmitted to the mounting surface via the dust-proof spring is reduced, and leakage of the vibration energy to the mounting surface through the dust-proof spring can be suppressed. Further, since the pitching operation is suppressed, even if the frequency is increased, the vibration is not easily disturbed and the posture of the transported article is stabilized. Therefore, high-speed transportation is possible, and the uniformity of the conveying state such as the conveying speed along the conveying path, .
In the present invention, it is preferable that a conveying path for conveying the conveyed matter is provided on at least one of the upper mass body and the lower conveying body, the upper vibration spring and the lower vibration spring have a vibration angle inclined to the opposite side in the vertical direction, The upper mass body and the lower mass body are vibrated in an inclined direction opposite to each other in the up and down direction by the excitation force of the in-phase image obtaining means, so that the one mass in the conveying direction Or the other side can be imparted to the conveyed object. Therefore, it is not necessary to arrange the vibration system as a whole in order to cause a conveying force for the conveyed object, so that the structure can be simplified and the conveying force adjustment operation can be facilitated. Since the vibration directions of the upper mass body and the lower mass body oscillating synchronously are inclined to the opposite sides of the upper and lower sides, the damping effect on the rotational moment of the upper mass body and the vertical direction components of the rotational moment of the lower mass can be enhanced , It becomes possible to reduce the reaction force in the vertical direction that the reference mass receives. Therefore, it is possible to stabilize the conveying condition of the conveyed object on the conveying path, to improve the conveying speed by the high frequency of the apparatus, and to suppress the leakage of the up-and-down vibration to the mounting surface through the vibration springs. Particularly, in the case of achieving a significantly higher frequency of 300 Hz to 1 kHz than the conventional case, even when the dynamic balance is slightly imbalanced in the up and down direction, the conveyed matter is shaken by the up-down vibration, Or the vertical vibration is transmitted from the mounting surface to the surroundings. However, according to the configuration of the present invention, the up-and-down motion of the transported article is reduced by lowering the vertical vibration, and the transported posture of the transported article is stabilized. Therefore, the transported articles can be aligned, sorted, and transported at a high density, It is possible to suppress the propagation of the up-and-down vibration.
In the present invention, as described above, in order for the upper vibration spring and the lower vibration spring to have a vibration angle, for example, the upper vibration spring and the lower vibration spring may be provided in an inclined posture as a whole . In this case, in order for the upper vibration spring and the lower vibration spring to have a vibration angle on the opposite side in the up-and-down direction, the upper vibration spring and the lower vibration spring may be inclined to the opposite side in the up-down direction as a whole. However, in the structure in which the attachment work of the spring is facilitated and the vibration angle is adjustable, the upper vibration spring and the lower vibration spring all have a plurality of spring elements, and the spring elements on the reference mass side And the spring elements on the side of the upper mass and the side of the lower mass have a spring structure disposed on one side in the carrying direction.
In this case, the upper vibrating spring has an upper vibrating spring main body and an upper connecting portion connecting the upper end of the upper vibrating spring main body with the upper mass body in the carrying direction, Wherein an upper side spring element is provided on the one side in the conveying direction with respect to the main body, and the upper side spring element is configured such that the upper side mass body is rotatable about an axis orthogonal to the conveying direction and the vertical direction with respect to the upper side vibrating spring main body Wherein the lower vibration spring has a lower vibration spring main body and a lower connecting portion for connecting the lower end portion of the lower vibration spring main body in the carrying direction with respect to the lower mass body, In the transport direction, The element is provided, the lower spring elements, preferably with respect to the lower spring vibration body is elastically deformed by the lower the mass body can rotate in the transport direction and the vertical direction and which is perpendicular to the axis circumferential form. With this arrangement, in the upper connecting portion and the lower connecting portion, the upper mass member or the lower mass member is disposed with respect to the upper end portion of the upper vibration spring main body or the lower end portion of the lower vibration spring main body via the upper spring element or the lower spring element disposed on the other side in the carrying direction The vibration direction of the conveying path provided for the upper mass body or the lower mass body is shifted in a direction inclined to the opposite side of the upper and lower sides with respect to the conveying direction in the same manner as in the case where the upper vibration spring and the lower vibration spring itself are provided in an inclined posture . In this case, the vibration angles of the upper vibration spring and the lower vibration spring are set such that the distance between the upper connecting end of the upper vibration spring body and the upper spring element in the carrying direction, In the transport direction. Therefore, it is possible to adjust the vibration angle of the upper side vibration spring and the lower side vibration spring only by adjusting the interval by a spacer or the like. Here, the upper spring element or the lower spring element may be formed by connecting the upper vibration spring main body or the lower vibration spring main body and the upper mass body or the lower mass body in a width direction (horizontal direction) orthogonal to the carrying direction and the vertical direction A connecting plate in the form of a leaf spring can be used. The connecting plate is capable of elastically deforming the upper mass body or the lower mass body in the direction in which the upper mass body or the lower mass body rotates about the axis in the width direction with respect to the upper connecting end of the upper vibrating spring body or the lower connecting end of the lower vibrating spring body, . In this case, the upper vibration spring main body is disposed in a posture extending in the vertical direction between the reference mass body and the upper mass body, and the lower vibration spring body is disposed between the reference mass body and the lower mass body It is preferable that they are disposed in a posture extending in the vertical direction. The upper vibration spring and the lower vibration spring can be provided with the vibration angle by providing the upper spring element and the lower spring element in the upper connecting portion and the lower connecting portion as described above. It is possible to cause the conveying force to be generated. Since the upper vibration spring main body and the lower vibration spring main body are in a vertical posture, it is possible to simplify the structure and reduce the up-and-down vibration, so that the stability of the carrying posture can be ensured even if the frequency is increased, It is possible to reduce the leakage of the vibration through the vibration plate.
As another example of the spring structure in which the plurality of spring elements are arranged as described above, the upper vibration spring and the lower vibration spring are vertically divided in the middle of the extending direction (vertical direction), and the lower ends of the divided upper- The upper end of the lower leaf spring portion may be connected in a stepped shape with a spacer or the like having a thickness in the carrying direction interposed therebetween if necessary. In this case, in order for the upper vibration spring and the lower vibration spring to have an inclined angle of inclination to the opposite side in the up-and-down direction, the side where the upper end of the lower leaf spring portion with respect to the lower end of the upper- It is preferable that the side where the upper end of the lower side plate spring portion with respect to the lower end of the upper side plate spring portion of the lower side vibration spring is disposed on the opposite side in the carrying direction. For example, the upper side vibration spring is constituted by a series connection structure of an upper piezoelectric driving part arranged at the lower side and an upper side amplifying spring arranged at the upper side, and a lower piezoelectric driving part in which the lower vibration spring is disposed at the upper side, The lower amplifying spring is connected to one end of the upper amplifying spring on one side in the carrying direction via an interval as required and the lower amplifying spring is connected to the lower end of the lower piezoelectric driving part, The upper end of the spring may be connected to one side (on the above-mentioned side) in the carrying direction with an interval as required. Also in this case, it is preferable that the upper side vibration spring and the lower side vibration spring are all arranged in a posture in which the upper side plate spring portion and the lower side plate spring portion extend in the vertical direction, respectively. Thereby, the structure can be simplified and the up-and-down vibration can be reduced. Therefore, even when the frequency is increased, the stability of the transporting posture can be ensured and the leakage of vibration through the vibration springs can be reduced.
In the present invention, it is preferable that the in-phase excitation means comprises: an upper excitation portion which directly applies the excitation force between the reference mass and the upper mass, and an upper exciter which directly applies the excitation force between the reference mass and the lower mass It is preferable to have the lower-side vibrating part. According to this configuration, the upper exciter and the lower exciter are directly and separately applied with an exciting force, so that the entire structure of the apparatus can be simplified, and the coincident means can be easily adjusted according to the situation. In this case, the upper vibrating part is constituted by the upper piezoelectric driving part and is mounted to a part of the longitudinal direction of the upper vibrating spring, the lower vibrating part is constituted by the lower piezoelectric driving part, and part of the upper vibrating spring in the longitudinal direction As shown in Fig. Thus, the upper piezoelectric driver and the lower piezoelectric driver are mounted on a portion of the upper vibration spring and the lower vibration spring, which elastically connect the reference mass, the upper mass and the lower mass, in the longitudinal direction thereof, so that the distance between the reference mass and the upper mass It is possible to simplify the structure, and at the same time, it becomes possible to easily cancel or attenuate the reaction force generated in the main vibration system. Here, it is preferable that the upper vibrating spring has a structure in which a plate-shaped upper amplification spring having the upper piezoelectric driving portion and a plate surface facing the carrying direction are connected in series. It is also preferable that the lower vibration spring has a structure in which a plate-shaped lower amplifying spring having the upper piezoelectric driving part and a plate surface facing the carrying direction are connected in series. The upper piezoelectric driver and the lower piezoelectric driver have a plate-shaped elastic substrate having a plate surface facing the carrying direction and a piezoelectric substance laminated on at least one of the front and back surfaces of the elastic substrate. The alternating voltage is applied in the thickness direction of the piezoelectric substance Thereby causing the elastic substrate to bend back and forth in the carrying direction, thereby generating vibration.
In this case, the in-phase excitation means is constituted such that both sides in the width direction are coupled to the reference mass in the vertical direction and portions extending above the reference mass form the upper piezoelectric driving portion, It is preferable that the piezoelectric actuator is a plate-like piezoelectric actuator in which the lower portion of the mass body forms the lower piezoelectric driver, and the plate surface as a whole is deflected in an upward and downward direction as a whole. According to this configuration, the upper piezoelectric driving portion, which is extended to the upper side of the reference mass, is connected to both sides in the width direction of the middle portion of the piezoelectric actuator integrally composed of the lower mass Since the driving portion has the lower mass, a stable connection state with respect to the reference mass can be obtained, and the upper mass and the lower mass can be easily and surely vibrated in the same phase reliably by the upper and lower bending deformation. In addition, since the upper mass body and the lower mass body can be provided with the piezoelectric actuator body as a single body, the height of the entire device can be reduced, and the device can be made compact. In this case, it is preferable that the piezoelectric actuator include a piezoelectric member that extends vertically to both sides at the coupling position with respect to the reference mass. In the present invention, for example, it is also possible to constitute the upper piezoelectric driving portion above the reference mass and the lower lower piezoelectric driving portion with separate piezoelectric bodies, while the elastic substrate is integrally formed. However, as described above, by providing a single piezoelectric member extending on both the upper and lower sides of the reference mass as described above, it is possible to enhance the unity of the flexural deformation of the piezoelectric actuator. Therefore, the upper mass member and the lower mass member can be more uniformly excited, The structure can be simplified, the manufacturing cost can be reduced, and the upper and lower vibration modes can be easily made uniform.
In the present invention, it is preferable that the upper piezoelectric driver includes an elastic substrate and a piezoelectric member laminated on the elastic substrate, and the upper amplification spring is integrally formed with the elastic substrate. It is preferable that the lower piezoelectric driver includes an elastic substrate and a piezoelectric member laminated on the elastic substrate, and the lower amplifying spring is integrally formed with the elastic substrate. This eliminates the need to connect at least one of the upper and lower piezoelectric driving parts and at least one of the upper and lower amplifying springs with bolts or the like. Thus, the number of parts and the number of assembling steps can be reduced, The height of the apparatus can be reduced. In particular, it is preferable that the elastic substrate of the upper piezoelectric driving part is formed integrally with the upper amplifying spring, and the elastic substrate of the lower piezoelectric driving part is formed integrally with the lower amplifying spring. In the case where the upper piezoelectric driving portion and the lower piezoelectric driving portion are constituted by integral piezoelectric actuators (when the elastic substrate of the upper piezoelectric driving portion and the elastic substrate of the lower piezoelectric driving portion are integral with each other), the elastic substrate And both the upper side amplification spring and the lower side amplification spring are integrally formed. At this time, the piezoelectric actuator itself can be installed in a vertical posture. It is preferable that the upper amplification spring and the lower amplification spring are formed to be thinner than the upper piezoelectric driver and the lower piezoelectric driver. According to this, damage to the upper piezoelectric driver and the lower piezoelectric driver can be avoided, and the amplitude can be secured by the upper amplification spring and the lower amplification spring.
In the present invention, it is preferable that the integral piezoelectric actuator is formed separately from the upper amplification spring and the lower amplification spring, and the upper side connection structure and the lower side connection structure for connecting and fixing the upper side amplification spring and the lower side amplification spring via bolts, When the structure is provided, it is preferable that the upper connection structure and the lower connection structure are provided by extending the elastic substrate upward and downward from the region where the piezoelectric body is stacked. The thickness of the upper connecting structure and the lower connecting structure is shifted from the thickness range of the region where the piezoelectric body is laminated in the carrying direction so that the upper and lower amplifying springs and the lower amplifying springs It is possible to adjust the vibration angle or change the adjustment range of the vibration angle. The amount of displacement of the upper and lower piezoelectric actuators and the lower and upper amplification springs in the carrying direction has a positive correlation with the vibration angle and the amount of displacement of the thickness range or the spacing of the spacers It can be set by thickness.
In the present invention, the lower end of the upper amplifying spring is fixedly connected to the upper connecting structure in the overlapping state on the one side in the carrying direction, and the upper end of the lower amplifying spring is connected to the lower connecting structure In a direction perpendicular to the first direction. This makes it possible to form the vibration angle irrespective of whether or not the spacer is interposed between the upper amplification spring and the lower amplification spring, the upper piezoelectric driver and the lower piezoelectric driver. In this case, as described above, it is possible to adjust or optimize the vibration angle by providing a displacement of the thickness range between the portion where the piezoelectric body is laminated in the piezoelectric actuator and the upper connecting structure and the lower connecting structure . In addition, since the upper connecting structure and the lower connecting structure are configured to be thinner than the portion where the piezoelectric body is laminated, it is possible to constitute the upper amplifying spring and the lower amplifying spring together with the amplifying action of the flexural deformation generated by the piezoelectric body , The lengths of the upper side amplification spring and the lower side amplification spring can be shortened.
In this case, it is preferable that the upper piezoelectric driver and the lower piezoelectric driver have a structure that is substantially symmetrical with respect to the coupling position with respect to the reference mass. According to this structure, the upper and lower piezoelectric actuators having the symmetrical structure can be symmetrically operated in both the upper and lower sides. When the connection structure in which the piezoelectric actuators integral with the reference mass are combined at both sides in the width direction is adopted as described above, the piezoelectric actuator is configured such that the horizontal line connecting the joining portions on both sides in the width direction is symmetrical, Structure.
In the present invention, it is preferable that the piezoelectric actuators are provided on both sides in the width direction with respect to the reference mass, and the piezoelectric bodies are disposed between the engagement positions. According to this configuration, since the piezoelectric actuator and the reference mass are coupled at both sides in the width direction, and the piezoelectric body is disposed between the coupling positions, uniform stiffness can be secured on both sides in the width direction with respect to the reference mass, It can be easily realized. Particularly, it is possible to prevent the bending deformation of the upper and lower bodies of the piezoelectric actuator from being hindered, and to realize an efficient and stable upper and lower-level driving state. Here, it is preferable that a piezoelectric body integrally formed on both upper and lower sides of the coupling portion is formed in the piezoelectric actuator.
In the present invention, it is preferable that the reference mass is supported from below by the pair of vibration springs. The support of the reference mass by the anti-vibration spring can be carried out from any direction. With this structure, the installation area of the entire apparatus can be reduced as compared with the case where the reference mass is suspended or supported from the side. The pair of anti-vibration springs are each constituted by a plate spring in a vertical posture along a vertical plane perpendicular to the conveying direction (connection direction) from the reference mass toward the mounting face desirable. Since the vibration springs are formed of leaf springs in a vertical posture, vibration components in the vertical direction of the reference mass can be reduced, so that it is possible to stabilize the transporting posture and reduce leakage of vibration to the mounting surface. The pair of anti-vibration springs may be any of the following two configurations in any of the above-described directions of support. One configuration is such that the pair of vibration springs are located at the front and rear support positions in the conveying direction with respect to the position where the upper vibration spring and the lower vibration spring (or the piezoelectric actuator) The reference masses are respectively supported on the reference masses. In this case, the assembling operation of the apparatus is facilitated, and the stability of the main vibrometer in the carrying direction can be enhanced. Another configuration is such that a pair of anti-vibration springs are provided at both the forward and backward support points in the carrying direction with respect to the position where the upper vibration spring and the lower vibration spring (or the piezoelectric actuator) And supports the reference masses on the same side (one side or the other side). In this case, the positional relationship of the reference mass in the transport direction between the position where the reference mass receives the reaction force from the upper vibration spring and the lower vibration spring and the position where the support mass receives the support force from the vibration springs is the same The stability of the main vibration system in the vertical direction and the width direction can be enhanced, and as a result, the conveying mode of the conveyed object can be further stabilized. In particular, even when the conveying speed is increased by raising the driving voltage of the piezoelectric actuator, a uniform conveying speed can be obtained over the entire length of the conveying path, and the conveying posture becomes stable.
In the present invention, it is preferable that the reference mass includes a pair of horizontally anti-vibration springs, each of which is composed of a dust-proof spring and a leaf spring disposed in a horizontal posture along the transport direction, at a position before and after the transport direction It is preferable that they are respectively supported by a dust-proof structure. According to this configuration, since the vibration component in the conveying direction and the vibration component in the vertical direction of the reference mass having mutually different vibration modes can be absorbed by different plate springs, the spring characteristics of the plate springs can be optimized, Leakage of vibration can be further reduced. In this case, a base for supporting the reference mass is provided via the vibration-proof spring, and the base includes an upper support rod to which the vibration-proof spring is connected, and a lower support rod . According to this configuration, in the state where the vibration of the reference mass vibrating in the carrying direction is absorbed by the anti-vibration spring, the remaining small vertical movements are absorbed by the horizontal vibration springs, so that both the vibration in the carrying direction and the vertical movement can be reliably absorbed can do. Further, by providing the horizontal vibration springs having large occupancy planes in the base by supporting the reference mass with the dust-proof springs having small occupancy planes, the space efficiency can be increased and the apparatus can be made compact.
In this case, it is preferable that the connecting directions of the pair of horizontal vibration springs provided at the front and rear positions in the carrying direction from the upper support to the lower support are mutually reversed before and after the conveying direction. According to this configuration, when the horizontal vibration springs provided at the front and rear positions in the carrying direction are vertically flexed and deformed in accordance with the vertical vibration of the main vibration system, the connection directions of the horizontal vibration springs are reversed in the forward and backward directions in the carrying direction , The locus of the arcuate shape of the bending deformation of each horizontal vibration springs is bent to the opposite side in the carrying direction. Therefore, the elastic deformation of the horizontal vibration springs at the front and rear positions in the carrying direction interferes with each other, so that the horizontal vibration springs are less likely to be elastically deformed as the amplitude of the vertical vibration becomes larger. The support stability of the main vibration system can be improved.
In the present invention, it is preferable that the transport path is provided in the upper mass body. As described above, the conveying path may be provided in at least one of the upper mass body and the lower mass body. In particular, by providing the conveying path in the upper mass body, it becomes easy to handle the apparatus and the conveyed object at the time of operation.
In the present invention, it is preferable that the mass of the reference mass is substantially equal to or greater than the sum of the masses of the upper mass and the lower mass. Since the mass of the reference mass, the mass of the upper mass, and the mass of the lower mass are in a relationship canceling out the reaction force in the mutual carrying direction (vibration direction), the mass of the reference mass is substantially equal to the sum of the masses of the upper mass and the lower mass, . However, since the reference mass is supported and restrained by the anti-vibration spring at the same time, the amplitude of the reference mass can be suppressed by increasing the mass of the reference mass relative to the sum of the masses, Since the amplitude can be increased, the vibration energy flowing to the mounting surface can be suppressed, and a sufficient carrying force can be ensured in the upper mass body or the lower mass body, so that a more stable vibration form can be realized.
In the present invention, the mass of the upper mass and the mass of the lower mass are substantially equal to each other, and the center spacing and the spring constant between the reference mass and the upper mass and the center distance between the reference mass and the lower mass, It is preferable that the spring constant is substantially equal. According to this, since the inertia mass and the elastic connection form of the upper mass body and the lower mass body are symmetrically formed with respect to the reference mass, the rotation moment can be canceled to further reduce the pitching operation.
In the present invention, it is preferable that the transport path is a linear shape, and the transport direction is a direction along a straight line. The present invention relates to an oscillatory transfer device having a rotary oscillator in which a direction of oscillation (a tangential direction around an axis) around a predetermined axis is a vibration direction and a spiral-shaped transfer path provided on the rotary oscillator, The present invention is also applicable to a case where conveyed articles are conveyed along a spiral-shaped conveying path by vibration. However, in the case of transporting the transported object linearly along the straight transport path, as shown in the following embodiments, the apparatus structure can be simplified and the transport speed can be improved and the transport state can be easily stabilized .
According to the present invention, it is possible to provide a vibratory transfer device capable of easily achieving high-frequency hydration of a vibration or speeding up of a conveying speed and stabilizing a conveying posture of a conveyed object with a simple structure, It can bring an excellent effect.

When the vibratory transfer device is designed to have a low drive frequency (resonant frequency), it is preferable that the vibration mode is a mode other than the original vibration mode having a vibration direction that faces obliquely upward toward the carrying direction F and diagonally downward toward the reverse direction The influence on the conveyance by the vibration mode is not so much a problem. However, if the device structure is designed so as to have a high carrier frequency (resonance frequency) so that the transported object is transported at a high speed, the transported object is likely to jump up and down and left and right on the transport route, Or the conveying posture of the conveyed object changes during conveyance. Further, the conveying speed largely changes along the conveying path, and the uniformity of the conveying speed on the conveying path along the conveying direction D is lost. As a result, the conveying efficiency of the conveying material (actually, the conveying material is supplied to the exit of the conveying path The speed is rate-controlled by a portion having the lowest conveying speed along the conveying path) may be lowered.
