<invention motivation>

However, in the conventional vibrating transport apparatus as disclosed in Patent Document 1, the inertial mass body (22) is directly connected to the vibrating body (21) to the side opposite to the exciter mounting member (23). Vibration occurs between the inertial mass body (22) and the exciter mounting member (23). Therefore, there are problems in that the exciter body (21) and the inertial mass body (22) for resisting the inertial force of the transport body (25) The vibration form of the entire exciter mounting member (23) is less likely to correspond to the vibration form of the transport body (25), and the reaction force of the transport body (25) cannot be sufficiently absorbed, and the vibration transmission board cannot be greatly suppressed. The vibration energy transmitted from the intermediate portion of the spring (26) to the connecting member support piece (28). In addition, in this structure, there is also a problem that it is easy to excite The body (21), the inertial mass body (22), the exciter mounting member (23), the transport body (25), and the vibration transmitting leaf spring (26) generate up and down motion (pitch motion) along the transport direction as a whole. The vibration of the up-and-down motion can easily flow out toward the side of the joint member supporting piece (28), and causes unevenness in the conveying speed of the conveying body (25) in the conveying direction or instability of the conveying state of the conveying object.

Further, in the conventional vibrating conveyor device as disclosed in Patent Document 2, since the excitation bodies (20a, 20b) are directly driven to the grooves (11), it is difficult to prevent the reaction from being damped from the leaf spring mounting body (14). It is transmitted by the leaf spring (15), and in order to obtain sufficient anti-vibration effect, it is necessary to interpose another excitation body (21a, 21b) between the leaf spring mounting body (14) and the weight (13), and Since the other excitation elements (21a, 21b) are controlled by the detection values of the reaction force detectors (22) provided on the vibration-proof leaf springs (15), there is a problem that the mechanical structure and the control of the excitation body are complicated. . Further, in this configuration, it is possible to cancel the reaction in the transport direction by the control between the pair of exciter bodies, but it is difficult to suppress the entire structure disposed on the vibration-proof leaf spring (15) from moving up and down along the transport direction. Since the motion (pitch motion) is performed, it is difficult to achieve sufficient suppression of the vibration energy outflow and uniformity of the transport speed or stability of the transport state.

Further, in the conventional vibrating transport apparatus of the above-described Patent Documents 3 and 4, the vibration energy can be suppressed from flowing out to the base (1) to some extent, but in the same manner as in Patent Document 1, the pressure is applied. The inertial body (6) is connected to the opposite side of the electric drive body (3), and the effect of reducing the reaction force of the transport body (2) due to the inertial force of the inertial body (6) is insufficient. Further, when the mass of the inertial body (6) is increased, it is easy to connect the connecting member (4) to the front and rear sides of the inertial body (6) via the piezoelectric driving body and to the connecting member via the amplification spring (5). (4) Transportation Since the body (2) generates up-and-down motion (pitch motion) along the transport direction, there is actually a uniformity in transport speed or a transport state in which the transport speed fluctuates along the transport direction or the transported material is easily swayed. Stability related issues.

<Invention purpose>

Accordingly, the present invention has been made in order to solve the above problems, and an object of the invention is to provide a vibrating transport apparatus capable of suppressing vibration energy flowing from a device to a installation surface more effectively than the prior art. Further, an object of the present invention is to achieve uniformization of a conveyance speed or stabilization of a conveyance posture by reducing up and down movement in a conveyance direction.

In view of the above, the vibrating conveyor of the present invention includes a transport body (11, 31) including a linear transport path for transporting a transported object, and a plate-shaped first elastic body (12a, 12b, 32a, 32b) elastically supporting the conveying body in front of and behind the conveying direction (F) so as to be capable of flexing deformation in the conveying direction; connecting members (13a, 13b, 13a', 13b) ', 33), which is connected to the lower side of the conveying body via the first elastic body; the second elastic body (14a, 14b, 34a, 34b) which is elastic from the lower side in front of and behind the conveying direction Supporting the connecting member; an excitation body (16a, 16b, 36, 37, 37') that imparts vibration in the conveying direction to the connecting member; a plate-shaped third elastic body (21a, 21b, 41a, 41b) which is connected to the connecting member in such a manner as to be flexibly deformable in the conveying direction; the inertial mass body (22, 22', 42) is elasticized via the third elastic body and the connecting member Connected and movable to the conveying direction; the conveying body and the Of the mass body vibrate in opposite phases.

According to the invention, the transport body is elastically supported by the first elastic body, the connecting member, and the second elastic body from below to be movable in the transport direction. At this time, when the vibration is applied to the connection member by the excitation member, the vibration is first to the connection member via the connection member. The elastic body propagates to vibrate the transport body in the transport direction. However, the inertial mass that is elastically connected to the connection member via the third elastic body is vibrated in a direction opposite to the transport body in the transport direction. Therefore, the amplitude of the connecting member can be sufficiently reduced, and the outflow of the vibration energy from the connecting member via the second elastic body can be suppressed more effectively than in the prior art. In addition, when the vibration energy flowing out to the installation surface is smaller than that in the prior art, the restriction force that the conveyor body receives from the installation surface side can also be reduced, so that unnecessary vibration generated in the conveyance body can be suppressed (for example, a pitch motion in the width direction is generated). Vibration, etc.). In particular, for the up-and-down motion (pitch motion) along the transport direction which is generated in each component assembly along the above-described vibration propagation path, it is also possible to utilize the third elasticity which is provided separately from the vibration propagation path and vibrates in the opposite phase. Since the body and the inertial mass are alleviated, it is possible to improve the uniformity of the conveying speed or the stability of the conveying state than the prior art.

In the present invention, it is preferable that the conveying body vibrates so as to move obliquely upward with respect to the horizontal direction toward the front in the conveying direction, the inertial mass body being oriented rearward in the conveying direction with respect to the horizontal direction Vibration is performed by moving diagonally upward. Thereby, it is possible to use the reverse action accompanying the swing of the inertial mass body by the influence of the vertical movement (the pitching motion along the transport direction) caused by the moving direction of the transport body or the acceleration and deceleration during the vibration of the transport body. By offsetting, it is possible to further reduce the outflow of vibration energy through the second elastic body, and it is possible to further improve the uniformity of the conveying speed or the stability of the conveying state.

In the invention, it is preferable that the inertial mass body is supported only by the third elastic body so as to be swingable in the conveying direction. Basically, as long as the inertial mass body is configured to be movable at least in the transport direction, it is possible to suppress the outflow of the vibration energy through the second elastic body, and according to this configuration, the inertial mass body can be supported to be swingable only by the third elastic body. This can effectively absorb the reverse of the swing of the transport body In particular, it is also able to absorb the reaction in the up and down direction. In this case, with respect to the direction of the swing of the inertial mass body, for example, the third elastic body is disposed in front of the transport direction with respect to the mounting position of the inertial mass body with respect to the attachment member mounting position. When the position is connected, the inertial mass body can be vibrated obliquely upward with respect to the horizontal direction toward the rear in the transport direction. It is particularly preferable to mount the third elastic body in an inclined posture from a mounting position with respect to the connecting member toward a position where it is mounted with respect to the inertial mass.

In the invention, it is preferable that a center of gravity of the inertial mass body is disposed at a position lower than a position at which the inertial mass body is mounted with respect to the connecting member. Thereby, the gravity center position of the transport body and the gravity center position of the inertial mass body are disposed on the opposite side to the upper side with respect to the connecting member, so that the reaction force (especially the up and down motion) received from the transport body can be effectively absorbed, and the inertial mass body can be reduced. the weight of. Here, when the center of gravity of the vibrating body is disposed at a position higher than the position at which the exciter body is attached to the connecting member, the exciter body and the inertial mass body can be efficiently disposed in the transport. Between the body and the installation surface, the device can be constructed compactly in the height direction.

In the present invention, it is preferable to have: the first connecting member that is connected to each of the first elastic body, the second elastic body, and the third elastic body that are disposed in front of the conveying direction; The connecting member is connected to the first elastic body, the second elastic body and the third elastic body respectively disposed behind the conveying direction; the first connecting member and the first The two connecting members are arranged apart from each other. Thereby, the first connecting member and the second connecting member which are disposed in the front and rear of the conveying direction are separately configured, and the first connecting member and the second connecting member are respectively independently of the transport body before and after the transport direction via the first elastic body. Since the vibration is excited, the vertical movement (pitching motion) of the transport body along the transport direction is less likely to occur than when the first connection member and the second connection member are integrated or integrally fixed. The uniformity of the conveying speed along the conveying direction or the stability of the conveying state is further improved.

In this case, it is preferable that the excitation body has a first piezoelectric driving body, one end of which is connected to the first connecting member, and a second piezoelectric driving body whose one end is connected to the second connecting member; And a component that connects and fixes the other end of the first piezoelectric driving body and the other end of the second piezoelectric driving body to each other. Thereby, the first connecting member and the second connecting member are respectively driven by the independent first piezoelectric driving body and the second piezoelectric driving body, so that up and down movement along the conveying direction can be further suppressed, and at the same time, due to the two piezoelectric driving bodies Since the other ends are connected and fixed to each other by the connecting member, the integration of the vibration system can be ensured, and variations in the driving form before and after the conveying direction can be suppressed. Further, since the connecting member also functions as an inertial body connected to the other end of the piezoelectric actuator, it is possible to improve the driving efficiency.

In the present invention, the vibrating body may be configured to generate vibration between the transport body and the connecting member, or may be configured to generate vibration between the connecting member and the inertial mass body. The exciter in the above case may be any one of a piezoelectric actuator and an electromagnetic actuator, and is preferably an electromagnetic actuator. In the case of the electromagnetic driving body, it is not necessary to restrict the components on both sides where the vibration is generated to the above, and therefore the canceling action of the vibration between the conveying body and the inertial mass body can be improved.

According to the present invention, it is possible to achieve an advantageous effect that the vibration type conveying device that can suppress the vibration energy flowing out from the apparatus to the installation surface more effectively than the prior art can be realized. In addition, it is also possible to improve the uniformity of the conveying speed or the stability of the conveying state.

Still images (a) and (b) extracted separately during displacement.

As shown in the first and second figures, the vibrating conveyor (10) is constituted by a trough (11a) and a conveying block (11b) indicated by a broken line in the figure fixed to the groove (11a). Transport body (11). The transport body (11) is not limited to the one shown in the figure, and the groove (11a) and the transport block (11b) are connected and fixed, and the two may be integrally formed. A conveying path (not shown) is formed linearly on the upper surface of the conveying block (11b). In the conveyance path, a conveyed object such as an electronic component (not shown) is conveyed in the direction of the arrow in the conveyance direction (F).

The upper end of the leaf spring-shaped amplifier spring (12a) is connected and fixed to the front end portion of the groove (11a) (the portion located at the forefront of the transport direction (F)). In addition, at the rear end of the groove (11a) (in the last direction of the conveying direction (F) The upper end of the augment spring (12b) in which the leaf spring shape is fixed is attached. The (lower end) of the above-described amplitude increasing spring (12a) is connected and fixed to a connecting member (13a) disposed in front of the conveying direction (F). Further, the (lower end) of the amplification spring (12b) is connected and fixed to the connecting member (13b) disposed behind the conveying direction (F). In the illustrated example, the lower ends of the amplification springs (12a, 12b) are connected and fixed to the upper portion of the connecting members (13a, 13b). Further, the amplitude increasing springs (12a, 12b) are respectively fixed to the outer side surfaces of the connecting members (13a, 13b) in the conveying direction (F) (the front side of the connecting member (13a) in front of the conveying direction (F), and in the conveying direction ( F) On the back of the rear connecting part (13b). The amplification springs (12a, 12b) are configured to be flexibly deformable in the conveying direction (F), whereby the conveying body (11) is elastically supported from below to be swingable in the conveying direction (F). The amplitude increasing springs (12a, 12b) correspond to the first elastic body described above.

The connecting member (13a) is connected to (the upper end of) the anti-vibration spring (14a) of the leaf spring shape. Further, the connecting member (13b) is connected and fixed to (the upper end of) the anti-vibration spring (14b) of the leaf spring shape. In the illustrated example, the upper ends of the anti-vibration springs (14a, 14b) are connected and fixed to the lower portion of the connecting members (13a, 13b). Further, the anti-vibration springs (14a, 14b) are respectively fixed to the front and rear outer side faces of the connecting members (13a, 13b) in the conveying direction (F) (the front side of the connecting member (13a) located in front of the conveying direction (F), On the back side of the connecting member (13b) behind the conveying direction (F). The anti-vibration springs (14a, 14b) correspond to the second elastic body described above. Here, the amplification springs (12a, 12b) and the anti-vibration springs (14a, 14b) are oriented obliquely upward with respect to the horizontal direction in the front and rear of the conveyance direction (F), respectively, toward the rear of the conveyance direction (F). tilt. In other words, all the springs are inclined such that their upper ends are located rearward of the conveying direction (F) than the lower ends. In addition, in the present embodiment, the amplitude increasing springs (12a, 12b) and the anti-vibration springs (14a, 14b) are substantially along to be transported from the bottom to the top. The direction (F) is arranged in front of the common plane inclined to the rear of the transport direction (F). However, the amplification springs (12a, 12b) and the anti-vibration springs (14a, 14b) do not need to be arranged strictly on the same plane, and may be arranged offset from each other. Here, the anti-vibration springs (14a, 14b) are configured to be flexibly deformable in the transport direction (F), thereby elastically supporting the connecting members (13a, 13b) in a state capable of swinging in the transport direction (F) from below. .

A (lower end) of the piezoelectric actuator (16a) disposed in front of the transport direction (F) is connected to the connecting member (13a). Further, (the lower end of the piezoelectric actuator (16b) disposed in the transport direction (F) is connected to the connecting member (13b). The piezoelectric actuators (16a, 16b) are plate-like bodies in which a piezoelectric body is fixed to an elastic metal plate (at least one of a front surface and a back surface) such as a backing plate. However, in the present embodiment, it is preferable to use a structure in which a piezoelectric body is fixed to both the front surface and the back surface of the elastic metal plate, or to laminate a plurality of piezoelectric layers on either one of the front surface and the back surface. The structure of the laminated piezoelectric body. In the case of the illustrated example, the piezoelectric actuators (16a, 16b) are disposed in parallel with the above-described amplification springs (12a, 12b) and the above-described vibration isolating springs (14a, 14b). Further, the piezoelectric actuators (16a, 16b) are configured to transmit flexural deformation in the longitudinal direction by applying a voltage to the front and back surfaces of the piezoelectric body, thereby transmitting a predetermined AC voltage to cause flexural vibration. Here, in the present specification, in the piezoelectric actuator or the plate-shaped elastic body, the dimension and direction along the propagation direction (deflection direction) of the vibration are referred to as "length" and "length direction", and The size and direction along the direction orthogonal to the propagation direction (deflection direction) are referred to as "width" and "width direction". Therefore, in the case of the present embodiment, the above-described amplitude increasing springs (12a, 12b), the above-described vibration isolating springs (14a, 14b), and the piezoelectric driving bodies (16a, 16b) are inclined in the vertical direction as the longitudinal direction. The direction and the width direction are set as the posture in the left and right direction.

The (upper end) of the piezoelectric actuator (16a) and the upper end of the piezoelectric actuator (16b) are connected and fixed to each other via a connecting member (17). In the illustrated example, the piezoelectric actuator (16a) and the piezoelectric actuator (16b) are connected and fixed to the front end surface and the rear end surface of the connecting member (17) in the transport direction (F). In the case of the present embodiment, the connecting member (17) is not connected to other members than the piezoelectric driving body (16a, 16b), and is separated from the groove (11a). In the case of the example of the figure, the connection member (17) is a plate-like body, and is configured in a horizontal posture in a reference posture (a posture in a static state in which vibration is not performed).

The lower ends of the anti-vibration springs (14a, 14b) are respectively fixedly coupled to the base (15). In the case of the illustrated example, the base (15) is formed in a convex shape in a side view so as to be higher in the middle portion of the conveying direction (F), and is connected and fixed on the step surface in front of the intermediate portion. The anti-vibration spring (14a) has a vibration-proof spring (14b) attached to the step surface on the rear side. With the above configuration, in the present embodiment, the transport body (11) is respectively accommodated by the amplitude increasing springs (12a, 12b), the connecting members (13a, 13b), and the anti-vibration spring (14a) in the front and rear of the transport direction (F). And 14b) elastically supported so as to be able to swing in the conveying direction (F). Here, the amplitude increasing springs (12a, 12b) and the anti-vibration springs (14a, 14b) are all inclined in the same direction in the conveying direction (F), so that when the two springs are flexibly deformed, the conveying body faces the conveying direction (F The front side is slightly inclined (for example, about 3 to 12 degrees) toward the upper side with respect to the horizontal direction. However, the configuration for realizing the same vibration form is not limited to the above-described form in which the leaf spring itself is inclined. For example, the lower end of the amplification springs (12a, 12b) may be mounted at a position ratio with respect to the connecting members (13a, 13b). The upper ends of the anti-vibration springs (14a, 14b) are connected with respect to the attachment position of the connecting members (13a, 13b) in the direction of the conveying direction (F), so that the amplifying springs (12a, 12b) are opposed to the anti-vibration springs (14a, 14b) ) Configured behind the conveying direction (F). At this point, you can set the two springs to hang Straight posture can also be set to a tilt posture.

One end (upper end shown) of a leaf spring-shaped connecting spring (21a) is connected and fixed to the connecting member (13a), and the other end (lower end of the drawing) of the connecting spring (21a) is fixedly coupled to the inertial mass body (22). )on. Further, one end (upper end shown) of a leaf spring-shaped connecting spring (21b) is connected and fixed to the connecting member (13b), and the other end (lower end of the drawing) of the connecting spring (21a) is connected and fixed to the inertial mass. On body (22). In the case of the illustrated example, the coupling springs (21a, 21b) are fixed to the front and rear end faces of the inertial mass body (22) in the conveying direction (F). Further, the inertial mass body (22) is disposed below the piezoelectric actuators (16a, 16b) and the connecting member (17). In the illustrated example, the inertial mass body (22) is transmitted through the plate-like portion (22a) to which the connecting springs (21a, 21b) are fixed and fixed, and is fixed in the front-rear direction in the conveying direction (F) than the plate-like portion (22a). The narrow additional mass portion (22b) is configured to be convex when viewed from the side. Thereby, even if the additional mass portion is thickly provided as shown in the example, the inertial mass body (22) does not interfere with the connecting members (13a, 13b) or the piezoelectric driving bodies (16a, 16b), and is transmitted through The inertia moment of the inertial mass body (22) can be increased by providing the additional mass portion (22b). However, the inertial mass body (22) is not limited to the configuration in which the plate-like portion (22a) and the additional mass portion (22b) are fixed as in the illustrated example, and the two may be integrally formed. It should be noted that the connecting springs (21a, 21b) correspond to the third elastic body.

The inertial mass body (22) can basically absorb the reaction force in the transport direction (F) received from the transport body as long as it can move in the transport direction (F), thereby suppressing vibration energy from the connection member (13a, 13b). ) outflow to the anti-vibration springs (14a, 14b). In the present embodiment, the inertial mass body (22) is connected to other members (connecting members (13a, 13b)) only via the connecting springs (21a, 21b), that is, Since it is elastically supported only by the connection springs (21a, 21b), the vibration system of this embodiment is configured to operate as a free end. Thereby, the inertial mass body (22) is swung by the connection springs (21a, 21b), whereby the reaction force received from the transport body (11) can be more effectively absorbed. Here, as shown in the example, it is preferable that the center of gravity of the inertial mass body (22) is disposed below the attachment position of the connection springs (21a, 21b) with respect to the connection members (13a, 13b). Thereby, with respect to the connecting members (13a, 13b), the conveying body (11) is elastically connected to the upper side, and the inertial mass body (22) is elastically connected to the lower side, so that the upper and lower parts can be transmitted through the connecting members (13a, 13b) The vibration balance is formed by the inertia balance of the sides to cancel each other out. Therefore, the center of gravity of the entire apparatus can be lowered to improve the stability, and the vibration of the connecting members (13a, 13b) can be easily reduced, and the propagation of the vibration via the anti-vibration springs (14a, 14b) can be further suppressed. It should be noted that the respective configurations described in this paragraph and their effects are the same in other embodiments to be described later.

In the present embodiment, as shown in the first figure, the anti-vibration springs (14a, 14b) and the coupling springs (21a, 21b) are disposed at positions close to or coincident when viewed from the conveying direction (F) (parallel in the width direction) As shown in the second figure, the center of the vibration-proof springs (14a, 14b) in the width direction is the opening (14c), and the connection spring is disposed in the opening surface of the opening (14c). 21a, 21b) is thus configured such that the two springs do not contact each other. Thereby, it is possible to easily increase the weight of the inertial mass body (22) while compactly configuring the entire apparatus (usually a portion other than the transport block (11b)) when viewed from the transport direction (F). In the illustrated example, bolts or nuts for fixing the upper and lower ends of the connection springs (21a, 21b) are also disposed in the opening portion (14c) so as not to come into contact with the vibration-proof springs (14a, 14b). The connection springs (21a, 21b) of the illustrated example are disposed inside the vibration-proof springs (14a, 14b) in front of and behind the conveyance direction (F) (the connection springs (21a) with respect to the vibration-proof springs (14a) Arranged in the rear of the conveying direction (F), the connecting spring (21b) is disposed in front of the conveying direction (F) with respect to the anti-vibration spring (14b), and is provided in parallel with the anti-vibration springs (14a, 14b).

Here, the opening portion (14c) of the anti-vibration springs (14a, 14b) and the left and right side portions thereof are symmetrically arranged in the width direction around the center axis of the connection springs (21a, 21b). . In this way, since the elastic support characteristics in the width direction of the transport body (11) or the inertial mass body (22) are less likely to vary, it is possible to prevent the drive efficiency from being lowered or the transport state due to the torsional vibration (the pitch motion in the width direction). Unstable. In the present embodiment, since the vibration-proof springs (14a, 14b) are disposed on both sides in the width direction of the connection springs (21a, 21b), it is easy to secure the vibration-proof springs (14a, 14b). The balance or stability of the elastic supporting force in the width direction, and the inertial mass body (22) is easily swung by increasing the elastic modulus of the connecting springs (21a, 21b) (the result is an enlarged swing amplitude), Thereby, the reaction force of the conveying body (11) can be sufficiently absorbed, which is preferable.

According to the present embodiment, the vibrations generated by the excitation elements (piezoelectric actuators (16a, 16b) and the connecting member (17)) are transmitted to the connecting members (13a, 13b), respectively, and further via the amplification springs (12a, 12b). Transfer to the transport body (11). On the other hand, as shown in the ninth drawings (a) and (b), in the resonance state, the reaction force received by the connecting members (13a, 13b) is transmitted to the transport body via the connecting springs (21a, 21b) ( 11) The opposite phase (the phase difference is 180 degrees) is absorbed by the inertial mass body (22) that oscillates, so that the transport body (11) can vibrate with sufficient amplitude while suppressing vibration energy from the anti-vibration spring (14a, 14b) ) outflow to the base station (15). In particular, the connection member is separately provided from the vibration transmission path from the excitation member via the connection members (13a, 13b) and the amplification springs (12a, 12b) toward the transport body (11). (13a, 13b) the connected connecting springs (21a, 21b) and the inertial mass body (22), so even in the transport body (11) constituting the vibration transmission path, the amplification springs (12a, 12b), and the connecting member (13a, 13b) The assembly of the piezoelectric actuators (16a, 16b) and the connecting member (17) has a vertical movement (pitching motion) along the conveying direction (F) as a whole, and can also be transmitted through a different body from the assembly. The reaction of the reaction of the springs (21a, 21b) and the inertial mass (22) reduces the up and down motion, so that the uniformity of the transport speed or the stability of the transport state can be improved.

Actually, as shown in FIGS. 9(a) and (b), the amplifying springs (12a, 12b) and the connecting members (13a, 13b) which elastically support the conveying body (11) in the front and rear of the conveying direction (F), respectively. And the vibration node of the elastic support structure formed by the anti-vibration springs (14a, 14b) is located at the joint portion of the connecting member (13a, 13b) and the anti-vibration spring (14a, 14b) as shown by the gray scale shown in the figure ( The lower portion of the connecting member (13a, 13b) or the upper portion of the anti-vibration spring (14a, 14b) is provided, and the connecting portion is hardly displaced. On the other hand, it is understood that the connecting springs (21a, 21b) connected to the connecting portion are largely flexed and deformed by the displacement of the inertial mass body (22).

In the conventional vibrating conveyor, when the weight of the base is not set large or the base is fixed to another weight (floor or the like), the conveying body cannot be sufficiently obtained due to the outflow of the vibration energy to the base. The amplitude is such that there is a problem that the conveyed material cannot be conveyed at a high speed, and the weight of the base is increased for this purpose. Further, in order to reduce the outflow of the vibration energy to the installation surface, an improvement is also made by further arranging the installation table below the base via an anti-vibration member such as a vibration-proof rubber or a coil spring. However, in the present embodiment, even if the weight of the base (15) is reduced as described above, it is possible to ensure a sufficient conveying force by the reaction force reducing action by the inertial mass body (22). For example, it can be clear with respect to an existing device having a weight of 35 kg as a whole. In the present embodiment including the transport body (11) having the same weight as the conventional device, the weight of the base (15) can be reduced by about 20 kg or less. Thereby, each operation such as loading, moving, and setting of the apparatus can be facilitated.

At this time, the connecting members (13a, 13b) from the front and rear of the conveying direction (F) drive the conveying body (11) via the amplification springs (12a, 12b), respectively, in terms of the driving portion, although the connecting member (13a) and (13b) is connected and fixed to the connecting member (17) via the piezoelectric driving body (16a, 16b), but the driving source (11) transmits the vibration driving source through the piezoelectric driving bodies (16a) and (16b) in the conveying direction The front and rear portions of (F) are independently excited, so that the pitching motion along the conveying direction (F) is less likely to occur than when the augmenting springs (12a) and (12b) are connected to the common member. In other words, when the connecting members (13a) and (13b) on the vibration transmission path of the transport body (11) are integrated with each other, the integration of the front and rear of the transport direction (F) of the entire vibration system is improved, so that it is easy to generate In the pitching motion along the conveying direction (F), the vibration direction is liable to be different at the joint positions of the amplifying springs (12a) and (12b) located at the front and rear of the conveying direction (F), and thus on the conveying body (11) It is also easy to generate up and down motion (pitch motion) along the transport direction (F), whereby the difference in transport speed is increased depending on the transport position, or the transport state becomes unstable. On the other hand, in the present embodiment, the connecting members (13a) and (13b) at the front and rear of the conveying direction (F) are separately formed, and in particular, the connecting members (13a) and (13b) are also driven by different piezoelectrics. The bodies (16a) and (16b) are driven so that the difference in the direction of vibration caused by the above-described pitching motion is less likely to occur. Therefore, it is possible to suppress a change in the conveying speed of the conveying body along the conveying direction (F) (conveying path) in accordance with the position along the direction, and it is possible to achieve a more uniform conveying speed. As a result, the transport body (11) can be formed long along the transport direction (F) without changing the front-back gap between the amplification springs (12a) and (12b) in the transport direction (F), Including The degree of freedom in design of manufacturing lines and the like is increased. Further, since the moving form when the conveying body (11) vibrates is close to the translational movement, the conveying posture of the conveying object is stabilized, whereby the stability of the conveying state is improved.

(Second embodiment)

Next, a second embodiment of the present invention will be described in detail. The third drawing is a side view of the vibrating conveying apparatus according to the second embodiment of the present invention, the fourth drawing is a front view of the second embodiment, and the tenth drawings (a) and (b) are showing the animation. a deformation pattern at the maximum amplitude before and after the conveyance direction, and a simulation image of the deformation amount of each portion which is stepwise indicated by the gray scale at this time, wherein the animation is a vibration analysis mode in which the vibration system resonates through the structural analysis program Animated while highlighted.

In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the common configuration is omitted. In the present embodiment, the transport body (11) (groove (11a) and transport block (11b)), the amplification springs (12a, 12b), the anti-vibration springs (14a, 14b), the base (15), and the piezoelectric drive The bodies (16a, 16b), the connecting member (17), and the connecting springs (21a, 21b) each have substantially the same configuration as that of the first embodiment.

In the present embodiment, the mounting position and the mounting angle of the connecting members (13a', 13b') with respect to the connecting springs (21a, 21b) and the plate-like portion (22a') of the inertial mass body (22') are relative to the above The attachment position and attachment angle of the connection springs (21a, 21b) are different from those of the first embodiment. Further, the connection springs (21a, 21b) are disposed at different positions (positions further rearward of the conveyance direction (F)) in the conveyance direction (F) with respect to the vibration isolation springs (14a, 14b). Further, the connecting springs (21a, 21b) are inclined in a direction opposite to the above-described amplification springs (12a, 12b) and the anti-vibration springs (14a, 14b).

Further, in the present embodiment, since the connecting spring (21a) itself is disposed rearward of the anti-vibration spring (14a) in the transport direction (F), the anti-vibration spring (14a) and the connecting spring (21a) itself Since they do not interfere with each other, it is not necessary to provide the anti-vibration spring (14a) with an opening (14c) for avoiding the connection spring (21a) or to displace the two springs in the width direction as in the first embodiment. However, in order to prevent the connection of the connecting spring (21a) to the connecting member (13a') and the inertial mass (22'), the bolt or nut does not interfere with the anti-vibration spring (14a), and is anti-vibration. The spring (14a) is provided with small opening portions (14c', 14d') for avoiding the above-mentioned bolts or nuts.

On the other hand, since the connection spring (21b) is also disposed behind the vibration-proof spring (14b) in the conveyance direction (F), the anti-vibration spring (14b) and the connection spring (21b) themselves do not mutually correspond to each other as described above. interference. In order to arrange the mounting position with respect to the connecting spring (21b) at a position rearward of the conveying direction (F) than the mounting position with respect to the anti-vibration spring (14b), the connecting spring (21b) and the inertial mass are simultaneously provided. The body (22') is coupled, and at least a part (rear end portion) of the connecting member (13b') and the inertial mass body (22') is provided with respect to the connecting spring (21b) protruding toward the rear of the conveying direction (F). a mounting portion (13b1') and a mounting portion (22a1'), and a mounting portion (13b1') and an inertial mass body for the connecting member (13b') are provided on a part of the anti-vibration spring (14b) The mounting portion (22a1') of 22') is a non-contact opening portion (not shown) that is similar to the small opening portions (14c', 14d') of the anti-vibration spring (14a).

In the present embodiment, basically the same operational effects as those of the first embodiment described above are achieved. Actually, as shown in the tenth (a) and (b), the vibration nodes are located at the connecting members (13a', 13b'), and the two springs connected to the connecting members (13a', 13b') are protected against each other. Vibration springs (14a, 14b) and connection springs (21a, 21b) In the middle, the lower ends of the connecting springs (21a, 21b) are largely displaced together with the inertial mass body (22'), and the anti-vibration springs (14a, 14b) are hardly deformed.

In the present embodiment, the coupling springs (21a, 21b) for connecting the inertial mass body (22') and the connecting members (13a', 13b') are oppositely inclined to the amplification springs (12a, 12b), thereby The up and down motion at the time of vibration also produces a different effect from the first embodiment.

In the first embodiment described above, in the first diagram, in the process of the front side of the transport body (11) facing the transport direction (F) (hereinafter simply referred to as "the case when the transport body is advanced"), in order to impart a transported object The forward force moves the transport body obliquely upward with respect to the horizontal direction toward the front of the transport direction (F) (arrow P). At this time, due to the moving direction or acceleration and deceleration, the transport body (11) is located in the transport direction ( F) The front portion is relatively temporarily raised (arrow U is shown), and the portion of the transport body (11) located behind the transport direction (F) is relatively temporarily lowered (arrow D is shown). On the other hand, when the transport body advances, the inertial mass body (22) moves obliquely downward with respect to the horizontal direction toward the rear of the transport direction (F) (arrow Q is shown), and at this time, the inertial mass body (22) The portion in front of the conveying direction (F) is relatively temporarily raised (arrow U is shown), and the portion of the inertial mass body (22) located behind the conveying direction (F) is relatively temporarily lowered (arrow D is shown). Therefore, the center of gravity of the front portion in the transport direction (F) of the vibrating transport device (10) rises when the transport body advances, and at the rear of the transport body toward the transport direction (hereinafter, simply referred to as "the transport body retreats" On the other hand, the center of gravity of the rear portion of the transport direction (F) of the apparatus descends when the transport body advances, and rises when the transport body retreats. As a result, in the vibrating conveyor (10), vertical movement (pitching motion) along the conveying direction (F) occurs in the entire vibration system with vibration, and the vibration-proof spring (14a, 14b) Transfer the up and down vibration to the base (15). Especially in the present embodiment, Since the vibration-proof springs (14a, 14b) are leaf springs, the front-back vibration of the conveyance direction (F) is easily absorbed by the deflection deformation of the leaf spring, but the up-and-down vibration is not easily absorbed by the leaf spring, so even the conveyance of the apparatus The up and down motion (pitch motion) of the direction (F) is not so large, and the vibration energy of the up and down motion component is also relatively large.

On the other hand, in the second embodiment, the connecting springs (21a, 21b) are inclined to the opposite side, whereby the inertial mass body (22') faces the rear of the conveying direction (F) when the conveying body advances. Moving obliquely upward (arrow Q' is illustrated), so that the portion of the inertial mass body (22') in front of the conveying direction (F) is relatively temporarily lowered (arrow D is shown), and the inertial mass body (22') is located The portion behind the conveying direction (F) is relatively temporarily raised (arrow U is shown). Therefore, in the vibrating conveying device (10'), the conveying body (11) and the inertial mass body (22') are moved up and down (pitching motion) opposite to each other, whereby the entire edge of the vibration system is generated along with the vibration. Since the vertical movement in the transport direction (F) cancels each other, the vertical vibration (pitch motion) itself is also reduced, and the transmission of the vertical vibration to the base (15) via the vibration-proof springs (14a, 14b) is also reduced, along the transport direction. The uniformity of the conveying speed of (F) or the stability of the conveying state is also improved.

In particular, in the present embodiment, since the anti-vibration springs (14a, 14b) are plate springs and do not easily absorb the up-and-down vibration, the suppression of the vertical movement (pitching motion) of the apparatus is very effective for reducing the outflow of the vibration energy. In fact, it can be confirmed that the vibrating conveyor (10') of the second embodiment can suppress the up-and-down vibration transmitted to the installation surface more than the vibrating conveyor (10) of the first embodiment, and can further improve Uniformity of delivery speed or stability of delivery state.

In addition, as described above, the configuration in which the inertial mass body (22') is oscillated obliquely upward with respect to the horizontal direction toward the rear of the transport direction (F) is not limited to the transmission of the connecting springs (21a, 21b). ) set to tilt posture to achieve, for example For example, the connecting springs (21a, 21b) may be divided into an upper half and a lower half, and the upper half and the lower half may be coupled to each other through a spacer having a thickness in the conveying direction (F). In other words, the upper end of the connecting springs (21a, 21b) is disposed at a position closer to the connecting member (13a', 13b') than the lower end of the connecting springs (21a, 21b) with respect to the inertial mass (22'). Further, the vibration form of the inertial mass body (22') described above can be realized by the position in front of the conveying direction (F).

Further, in the present embodiment, the connection spring (21a) is disposed at a position rearward of the vibration-proof spring (14a) in the conveyance direction (F), and the connection spring (21b) is also disposed in the anti-vibration spring (14b). More depends on the position behind the conveying direction (F). This is because, as described above, in order to cause the transport body (11) to vibrate obliquely upward with respect to the horizontal direction toward the front in the transport direction (F), the amplification springs (12a, 12b) are attached to the transport body (11). In the case where the positions are respectively disposed at positions closer to the transport direction (F) than the mounting position of the anti-vibration springs (14a, 14b) with respect to the base (15), the inertial mass body is easily formed in the device design (22). ') When the lower portion of the device is disposed rearward in the transport direction (F), it is easy to match the position of the center of gravity of the inertial mass body (22') with the position of the center of gravity of the transport body (11) in the transport direction (F).

Further, regarding the differences between the first embodiment and the second embodiment described above, each point of another embodiment may be arbitrarily selected and employed in any of the embodiments. Further, in any of the above embodiments, the assembly comprising the connecting member (13a) and the piezoelectric actuator (16a), and the assembly of the connecting member (13b) and the piezoelectric actuator (16b) are pressed. The electric drive body is assembled to be opposite to each other with respect to which side of the front and rear of the conveyance direction (F) the connection member is disposed, but is configured to avoid the increase of the spring (12a) or (12b) and the joint member ( 17) dry The two assemblies can also be assembled in the same direction with each other. Further, the upper ends of the piezoelectric actuators (16a) and (16b) before and after the transport direction (F) may be connected to different inertial bodies instead of being connected by a common connecting member (17) as described above. Further, any one of the piezoelectric actuators (16a) and (16b) connected to the connecting member (17) may be constituted only by a leaf spring.

(Third embodiment)

Next, a third embodiment of the present invention will be described in detail. Fig. 5 is a side view of a vibrating conveyor according to a third embodiment of the present invention, and Fig. 6 is a front view of the third embodiment, and Figs. 11(a) and (b) are diagrams showing an animation A deformation image at the maximum amplitude before and after the conveyance direction, and a simulation image of the deformation amount of each portion which is stepwise indicated by the gray scale at this time, wherein the animation is a vibration configuration of the vibration system The program emphasizes the animation shown.

The vibrating transport device (30) according to the present embodiment includes a transport body (31) including a groove (31a) and a transport block (31b) corresponding to each of the first and second embodiments, and an amplification spring (32a, 32b). ), anti-vibration springs (34a, 34b), abutments (35), connecting springs (41a, 41b), and inertial mass bodies (42). Basically, each of the above-described members has the same configuration as that of the first and second embodiments, and thus the description thereof is omitted. A transport block (31b) is fixed to the groove (31a), and a linear transport path (not shown) extending along the transport direction (F) is formed on the upper surface of the transport block (31b). The groove (31a) and the conveying block (31b) constitute a conveying body (31).

In the present embodiment, the lower ends of the amplification springs (32a) and (32b) before and after the conveying direction (F) are connected to the common connecting member (33). Similarly to the previous embodiment, the connecting member (33) is also connected to the anti-vibration springs (34a, 34b) and the connecting springs (41a, 41b). On the connecting part (33), integrated or fixed to each other The front portion (33a) connected to the expansion spring (32a) in front of the conveying direction (F), the anti-vibration spring (34a) and the coupling spring (41a), and the amplification spring (32b) in the rear of the conveying direction (F) are provided. The anti-vibration spring (34b) and the rear portion (33b) to which the connection spring (41b) is connected, and a plate-shaped connecting portion (33c) that connects the front portion (33a) and the rear portion (33b). An electromagnetic solenoid (36) including a magnetic core (36a) and a coil (36b) surrounding the magnetic core (36a) is attached and fixed to a front portion (33a) of the connecting member (33). The rear end surface of the magnetic core (36a) is configured as a magnetic pole. On the other hand, in the lower portion of the transport body (31) (groove (31a)), a counter member (37) constituting the opposing magnetic pole that extends downward and faces the rear end of the magnetic core (36a) is fixed. . Here, the electromagnetic solenoid (36) and the counter electrode member (37) constitute an electromagnetically driven exciter.

In the present embodiment, a magnetic force is generated between the magnetic core (36a) and the counter electrode member (37) by applying an alternating voltage to the electromagnetic solenoid (36), and the magnetic force is connected to the transport body (31). Vibrations in the conveying direction (F) are generated between the members (33), and the vibrations propagate through the amplification springs (32a, 32b) to vibrate the conveying body. At this time, similarly to the above-described respective embodiments, the inertial mass body (42) swings to cancel the reaction force generated by the transport body (31), and the outflow of the vibration energy to the base (35) is suppressed. Further, similarly to the second embodiment, the connection springs (41a, 41b) are inclined obliquely with respect to the amplification springs (32a, 32b) and the anti-vibration springs (34a, 34b), and therefore, basically, with the second embodiment Similarly, the vertical movement (pitching motion) of the entire vibration system along the transport direction (F) can be reduced, and the vibration energy flowing out to the base (35) can be further reduced.

Further, in the present embodiment, the front portion (33a) of the connecting member (33) is provided with a mounting portion (33a1) that protrudes further from the connection portion of the widening spring (32a) toward the front side in the transport direction (F), and the mounting portion (33a1) is attached thereto. Fixed anti-vibration bomb on the part (33a1) Spring (34a). Similarly, a mounting portion (33b1) that protrudes further from the connection portion of the amplification spring (32b) toward the rear of the conveying direction (F) is provided at the rear portion (33b) of the connecting member (33), and the mounting portion (33b1) is attached to the mounting portion (33b1). Connect the fixed anti-vibration spring (34b). According to this configuration, the interval between the anti-vibration springs (34a) and (34b) in the transport direction (F) can be largely ensured, and therefore, between the anti-vibration springs (34a) and (34b) as shown in the figure. The entire connection springs (41a, 41b) and the inertial mass body (42) are disposed, and since the arrangement space of the inertial mass body (42) can be largely ensured, a sufficient inertial force can be imparted. In addition, the mounting portion of the connecting member, the anti-vibration spring, and the structure of the connecting spring and the inertial mass disposed on the front and rear sides of the anti-vibration spring in the transport direction (F) may be in the first embodiment described above. Or adopted in the second embodiment.

In the present embodiment, the front portion (33a) disposed in front of the transport direction (F) and the rear portion (33b) disposed behind the transport direction (F) are provided as connection members (33) via the connection portion (33c). Since it is integrally formed, the excitation action is not independently applied in the front and rear of the conveyance direction (F) as in the first and second embodiments described above. However, since the exciter of the present embodiment is such that the vibration is generated between the connecting member (33) and the transport body (31), the connection is made two times before and after the transport direction (F) with the connecting member (33). The expansion springs (32a) and (32b) apply an exciting action given from the common connecting member (33), so that the conveying body can generate stable vibration with less vertical movement (pitching motion) along the conveying direction (F). . In the connection member (33), the connection portion (33c) may be configured to function as an elastic body that can be flexibly deformed.

(Fourth embodiment)

Next, a fourth embodiment of the present invention will be described in detail. First 7 is a side view of a vibrating conveyor according to a fourth embodiment of the present invention, and FIG. 8 is a rear view of the fourth embodiment, and FIGS. 12(a) and (b) are diagrams showing an animation. a modified image at the maximum amplitude before and after the transport direction, and a simulated image of the amount of deformation of each portion which is stepwise represented by a gray scale at this time, wherein the animation is a vibration analysis mode in which the vibration system resonates through the structural analysis program Animated while highlighted.

The vibrating transport device (30') of the present embodiment is an electromagnetically driven device including an electromagnetic solenoid (36) as in the third embodiment. In the present embodiment, the configuration of the third embodiment is basically the same as that of the third embodiment. Therefore, the same portions are denoted by the same reference numerals, and the description of the same configuration is omitted.

The present embodiment is different from the third embodiment in that the counter electrode member (37') that generates a magnetic force with the electromagnetic solenoid (36) is not connected and fixed to the transport body (31), but is connected and fixed to On the inertial mass body (42). Therefore, the exciter composed of the electromagnetic solenoid (36) and the counter electrode member (37') directly vibrates between the connecting member (33) and the inertial mass (42). However, the vibration generated by the exciter is transmitted from the connecting member (33) to the transport body (31) via the amplification springs (32a, 32b), and is transmitted through the vibration transmission path as in the third embodiment. Since the body (31) vibrates in the conveying direction (F), the same conveying action and effect as the third embodiment can be obtained.

Further, in the present embodiment, since the exciting force is not directly applied to the conveying body (31), the vibration is transmitted in the conveying direction (F) via the connecting member (33) and the amplification springs (32a, 32b). Therefore, the restraining force of the vibrating body against the vibration state is not easily directly applied to the conveying body (31), and the vibration shape of the conveying body (31) can be determined by the balance of the entire vibration system.

It is to be noted that the vibrating conveyor of the present invention is not limited to the above-described examples, and various modifications can be made without departing from the spirit and scope of the invention. For example, the respective configurations employed in the devices of the first to fourth embodiments described above can be used interchangeably in any combination as long as the configuration is not particularly hindered.
