But, be provided with in the existing vibrating type conveyer of counteraction counterweight above-mentioned, there is following problems, that is: in order to make the center of gravity of the center of gravity of conveying body and counteraction counterweight close or be arranged on same straight line and cause structure to complicate, thus larger-scale unit or manufacturing cost is caused to increase, further, owing to extremely critically must set center-of-gravity position, the manufacture scene thus constantly changed in the situation such as type or delivery speed of transported substance is difficult to obtain abundant effect.Especially, when improving driving frequency to carry at a high speed, also luffing or up-and-down movement etc. can be caused to become violent even if center-of-gravity position only exists slight deviations, thus appropriate feed status cannot be obtained, thus be difficult to realize high frequency or conveying at a high speed.

Therefore, the present invention completes to solve the problem, its problem is that providing a kind of can easily reduce by simple structure the antagonistic force putting on installation surface, and easily realizes the vibrating type conveyer of the high frequency of vibration or the high speed of delivery speed.

Summary of the invention

In view of above-mentioned actual conditions, the feature of vibrating type conveyer of the present invention is to possess: a pair antirattle spring, and it is separately positioned on the front and back position place of throughput direction, and is made up of the leaf spring had towards the plate face of described throughput direction; Reference mass body, it is supported by antirattle spring described in a pair at the front and back position place of described throughput direction; Upside mass body, it is configured in the top of described Reference mass body; Downside mass body, it is configured in the below of described Reference mass body; Vibrating spring on the upside of in the of a pair, described Reference mass body is connected with described upside mass body elasticity at the front and back position place of described throughput direction by respectively, and comprises the plate spring structure had towards the plate face of described throughput direction; Pair of lower vibrating spring, described Reference mass body is connected with described downside mass body elasticity at the front and back position place of described throughput direction by respectively, and comprises the plate spring structure had towards the plate face of described throughput direction; And homophase exciting agency, it applies disturbance force between described Reference mass body and described upside mass body and between described Reference mass body and described downside mass body, thus produces the vibration of homophase on described throughput direction; Further, at least one in described upside mass body and described downside mass body is provided with the transport road for carrying transported substance; Described upside vibrating spring and described downside vibrating spring have the angle of throw mutually tilted towards above-below direction opposition side, thus are made described upside mass body and described downside mass body vibrate along the direction mutually tilted towards above-below direction opposition side by the described disturbance force of described homophase exciting agency.

According to the present invention, above and below the Reference mass body that the front and back position place of throughput direction is supported by antirattle spring respectively, be elasticly connected with upside mass body and downside mass body respectively via vibrating spring at the front and back position place of throughput direction, and, homophase exciting agency is utilized to apply disturbance force, thus make upside mass body and downside mass body vibration in phase when observing from throughput direction, and Reference mass body and upside mass body and downside mass body vibrate in opposite phase when observing from throughput direction.Therefore, the center-of-gravity position of Reference mass body and the overall center-of-gravity position skew in the vertical direction of upside mass body and downside mass body can be reduced, the eliminating effect of the antagonistic force that the throughput direction that thus can improve Reference mass body and upside mass body and downside mass body vibrates.

In addition, when vibrating, upside mass body is contrary with the direction of downside mass body to the torque that Reference mass body applies to the direction of the torque that Reference mass body applies, the antagonistic force of the hand of rotation produced by vibration thus suffered by Reference mass body is cancelled out each other or is weakened, thus can suppress pitching motion (rotary motion).Therefore, the antagonistic force of the throughput direction and above-below direction that are passed to installation surface via antirattle spring is weakened, thus energy of vibration can be suppressed to leak to installation surface via antirattle spring.And then, because pitching motion is suppressed, also not easily make vibration disorderly even if thus improve frequency, and the attitude of transported substance also keeps stable, therefore, it is possible to realize at a high speed conveying, and also can improve the homogeneity along feed statuss such as the delivery speed of transport road or conveying attitudes.

In the present invention, at least one in described upside mass body and described downside mass body is provided with the transport road for carrying transported substance, described upside vibrating spring and described downside vibrating spring have the angle of throw mutually tilted towards above-below direction opposition side, thus made described upside mass body and described downside mass body vibrate along the direction mutually tilted towards above-below direction opposition side by the described disturbance force of described homophase exciting agency, thus, can be arranged at upside mass body and downside mass body at least one on transport road on to transported substance apply towards the side of throughput direction or the carrying capacity of opposite side.Therefore, without the need to by vibrating system whole installation for tilting to apply carrying capacity to transported substance, thus can simplification device structure, and make the adjustment operation of carrying capacity become easy.

In addition, because the upside mass body of synchronized oscillation and the direction of vibration of downside mass body are the directions mutually tilted towards above-below direction opposition side, therefore, the weakening effect of the above-below direction composition of the upside torque of mass body and the torque of downside mass body can be improved, thus the antagonistic force of the above-below direction suffered by Reference mass body can be reduced.Therefore, it is possible to realize following effect, that is: make the feed status of the transported substance on transport road become stable, delivery speed can be improved by improving the frequency of device, and up-down vibration can be suppressed to leak to installation surface via antirattle spring.

Especially when frequency being increased to this frequency far above existing frequency of 300Hz ~ 1kHz, even if the dynamical equilibrium of above-below direction is unbalanced a little, also the following state of affairs can be produced, that is: because of up-down vibration, transported substance is beated, thus not easily carry out the arrangement, sorting, high density conveying etc. of transported substance, or up-down vibration is passed to around from installation surface.But, according to formation of the present invention, by reducing up-down vibration, the bob of transported substance is reduced, thus make the conveying attitude of transported substance become stable, therefore, it is possible to carry out the arrangement, sorting, high density conveying etc. of transported substance, and up-down vibration can be suppressed to be transmitted to around from installation surface.

In the present invention, as mentioned above, in order to make described upside vibrating spring and described downside vibrating spring have angle of throw, as an example, described upside vibrating spring and described downside vibrating spring also can be configured to be set to integral inclined attitude respectively.In this situation, in order to make upside vibrating spring and downside vibrating spring have mutually towards the angle of throw of above-below direction opposition side, as long as upside vibrating spring and downside vibrating spring to be configured to respectively the overall attitude tilted towards above-below direction opposition side.

In the present invention, preferred described homophase exciting agency has exciting portion, upside and exciting portion, downside, wherein, on the upside of this, exciting portion applies described disturbance force directly between described Reference mass body and described upside mass body, and on the downside of this, exciting portion applies described disturbance force directly between described Reference mass body and described downside mass body.Thus, by being configured to by exciting portion, upside and exciting portion, downside directly and separately apply disturbance force independently, thus can the integral structure of simplification device, and easily according to circumstances can adjust homophase exciting agency.

In this situation, exciting portion, preferred described upside is made up of Piezoelectric Driving portion, upside, and be included in a part for the length direction of described upside vibrating spring, exciting portion, described downside is made up of Piezoelectric Driving portion, downside, and is included in a part for the length direction of described downside vibrating spring.Thus, being included in elasticity by making Piezoelectric Driving portion, upside and Piezoelectric Driving portion, downside connects in a part for the length direction of Reference mass body and upside mass body and the upside vibrating spring between Reference mass body and downside mass body and downside vibrating spring, disturbance force can be applied between Reference mass body and upside mass body and between Reference mass body and downside mass body by means of only upside vibrating spring and downside vibrating spring, thus can simplified structure, and can offset more easily or weaken the antagonistic force produced in principal vibration system.

At this, preferred described upside vibrating spring has the structure that Piezoelectric Driving portion, described upside and plate are connected in series facing to amplification spring on the upside of the tabular of throughput direction.In addition, preferred described downside vibrating spring has the structure that Piezoelectric Driving portion, described downside and plate are connected in series facing to amplification spring on the downside of the tabular of throughput direction.Piezoelectric Driving portion, upside and Piezoelectric Driving portion, downside are provided with plate facing to the plate-like elastic substrate of throughput direction and the piezoelectrics on being laminated in the surface of this elastic base plate or the back side at least any one face, and, by applying alternating voltage to the thickness direction of these piezoelectrics, described elastic base plate is bent before and after throughput direction, thus produce vibration.

In this situation, preferred described homophase exciting agency is made up of the Piezoelectric Driving body of tabular, wherein, the Width both sides of the above-below direction middle part of this Piezoelectric Driving body are combined on described Reference mass body, the part extended towards the top of described Reference mass body forms Piezoelectric Driving portion, described upside, the part extended towards the below of described Reference mass body forms Piezoelectric Driving portion, described downside, further, flexure deformation is integratedly presented down in the plate face towards described throughput direction of this Piezoelectric Driving body entirety.

Thus, be combined on Reference mass body by the both sides of the Width of the above-below direction middle part by the Piezoelectric Driving body formed in one, and utilize the Piezoelectric Driving portion, upside extended above Reference mass body to carry out exciting to upside mass body, the Piezoelectric Driving portion, downside extended below Reference mass body is utilized to carry out exciting to downside mass body, thus can make to keep stable with the coupled condition of Reference mass body, meanwhile, can by up and down one flexure deformation and easily and reliably make upside mass body and downside mass body in phase vibrate.In addition, due to exciting can be carried out by the Piezoelectric Driving body of one to upside mass body and downside mass body, thus can reduce the height of device entirety, thus make apparatus structure miniaturization.

In this situation, preferred described Piezoelectric Driving body has and to extend from the binding site of itself and described Reference mass body towards upper and lower both sides and piezoelectrics in one.In the present invention, such as, elastic base plate also can be made to be one, and utilize different piezoelectrics to form the Piezoelectric Driving portion, upside above Reference mass body and the Piezoelectric Driving portion, downside below Reference mass body.But, by arranging as mentioned above towards the piezoelectrics in one that the both sides up and down of Reference mass body extend, the globality of the flexure deformation of Piezoelectric Driving body can be improved, therefore, exciting can be carried out to upside mass body and downside mass body more equably, and can easily simplified structure, reduce productive costs and make upper and lower vibration shape uniformization etc.

In the present invention, Piezoelectric Driving portion, preferred described upside has elastic base plate and is laminated to the piezoelectrics on this elastic base plate, and described upside amplification spring and described elastic base plate are in forming integratedly.In addition, Piezoelectric Driving portion, preferred described downside has elastic base plate and is laminated to the piezoelectrics on this elastic base plate, and described downside amplification spring and described elastic base plate are in forming integratedly.Thus, due to without the need to using bolt etc. to connect up and down at least any one Piezoelectric Driving portion and at least any one amplification spring up and down, thus can reducing portion pieces number or assembling man-hour, and can by height corresponding with the height of this connecting bridge for device height reduction.The elastic base plate in Piezoelectric Driving portion, especially preferred upside and upside amplification spring are in forming integratedly, and the elastic base plate in Piezoelectric Driving portion, downside and downside amplification spring are in forming integratedly.

In addition, when Piezoelectric Driving portion, upside and Piezoelectric Driving portion, downside are made up of the Piezoelectric Driving body of one (when the elastic base plate in Piezoelectric Driving portion, upside and the elastic base plate in Piezoelectric Driving portion, downside are in one), preferably the elastic base plate of the Piezoelectric Driving body of this one and upside amplification spring and downside amplification spring are all in forming integratedly.Now, Piezoelectric Driving body itself can be set to perpendicular attitude.In addition, preferably described upside amplification spring and described downside amplification spring are formed as thickness and are less than Piezoelectric Driving portion, upside and Piezoelectric Driving portion, downside.Thereby, it is possible to avoid damaging Piezoelectric Driving portion and Piezoelectric Driving portion, downside, upside, and the amplitude that produced by upside amplification spring and downside amplification spring can be guaranteed.

In the present invention, form when the Piezoelectric Driving body of above-mentioned one separates with upside amplification spring and downside amplification spring, and when being provided with for being fastened on upside connection structure on upside amplification spring and downside amplification spring and downside connection structure by bolt and packing ring etc., upside connection structure and downside connection structure is set preferably by making elastic base plate have the region of piezoelectrics to extend with below upward from lamination.

In addition, by the thickness range of upside connection structure and downside connection structure being formed as when observing from throughput direction and lamination has the thickness range in the region of piezoelectrics to there is deviation, thus set upside amplification spring and departure in the conveying direction between downside amplification spring and Piezoelectric Driving body according to the departure of this thickness range, thus can adjust above-mentioned angle of throw or change the setting range of angle of throw.

Piezoelectric Driving portion, upside and upside amplification spring and departure in the conveying direction and angle of throw correlation between Piezoelectric Driving portion, downside and downside amplification spring, thus angle of throw can be set according to the thickness of the departure of above-mentioned thickness range or the distance piece be arranged between the two.

In the present invention, the lower end of preferred described upside amplification spring is fixed in the connection structure of described upside with the stateful connection of the described side overlap from described throughput direction, and the upper end of described downside amplification spring is fixed in the connection structure of described downside with the stateful connection of the described side overlap from described throughput direction.Thus, no matter in upside amplification spring and Piezoelectric Driving portion, upside and whether be provided with distance piece between downside amplification spring and Piezoelectric Driving portion, downside, all above-mentioned angle of throw can be formed.

In this situation, there is the deviation of thickness setting scope between the part of piezoelectrics and upside connection structure and downside connection structure by the lamination at Piezoelectric Driving body described above, thus can easily adjust angle of throw or make angle of throw reach best.In addition, the part that lamination has piezoelectrics is less than by upside connection structure and downside connection structure are configured to its thickness, together can play a role consisting of as the part with the effect increasing the flexure deformation that piezoelectrics produce with upside amplification spring and downside amplification spring, thus can shorten the length of upside amplification spring and downside amplification spring.

In this situation, preferred Piezoelectric Driving portion, described upside and Piezoelectric Driving portion, described downside have binding site relative to itself and described Reference mass body and in fact in upper and lower symmetrical structure.Thus, by having Piezoelectric Driving portion, upside and the Piezoelectric Driving portion, downside of symmetrical structure, symmetrical action form can be obtained in upper and lower both sides.In addition, when adopting the Piezoelectric Driving body by one described above to be combined in the connection structure on Reference mass body in Width both sides, the horizon that preferred described Piezoelectric Driving body has the binding site connecting Width both sides is upper and lower symmetrical structure as axis of symmetry.

In the present invention, the binding site of preferred described Piezoelectric Driving body and described Reference mass body is arranged on Width both sides, and piezoelectrics are configured between described binding site.Thus, by Piezoelectric Driving body is combined in Width both sides with Reference mass body, and piezoelectrics are configured between this binding site, thus can guarantee in Width both sides uniformly in conjunction with rigidity relative to Reference mass body, thus easily can realize stable exciting state.Especially can not hinder the flexure deformation of the one up and down of Piezoelectric Driving body, thus the driving condition of effective and stable homophase up and down can be realized.At this, be preferably formed in Piezoelectric Driving body in the both sides up and down of described binding site in the piezoelectrics formed integratedly.

In the present invention, preferably described Reference mass body is supported from below by antirattle spring described in a pair.Although antirattle spring can be utilized to support Reference mass body from any direction, when so forming, compared with when supporting Reference mass body from overhung or support Reference mass body from side, the setting area of device entirety can be reduced.In addition, preferably antirattle spring described in a pair is made up of the leaf spring being parallel to the perpendicular attitude of the vertical surface vertical with described throughput direction towards the closure (length direction) of described installation surface (base station) side from described Reference mass body respectively.By utilizing the leaf spring of perpendicular attitude to form above-mentioned antirattle spring, thus the vibration component of the above-below direction of Reference mass body can be reduced, conveying attitude thus can be made to become stable or reduce the vibration of leaking to installation surface.

No matter which kind of direction above-mentioned support direction is, antirattle spring described in a pair all can be formed as following two kinds form in any one.Wherein a kind of form be: the Support Position place before and after throughput direction, a pair antirattle spring respectively before the binding site comparing upside vibrating spring and downside vibrating spring (or Piezoelectric Driving body) and Reference mass body is closer to throughput direction posterolateral position support Reference mass body.In this situation, the assembling operation of device becomes easy, and can improve the stability on the throughput direction of principal vibration system.Another kind of formation is: the Support Position place before and after throughput direction, and a pair antirattle spring all supports Reference mass body at the binding site relative to upside vibrating spring and downside vibrating spring (or Piezoelectric Driving body) and Reference mass body in the same side (side or opposite side) of throughput direction respectively.In this situation, between position Reference mass body being applied to antagonistic force due to upside vibrating spring and downside vibrating spring and antirattle spring apply bearing force position to Reference mass body, position relationship a pair Support Position place before and after throughput direction is in the conveying direction identical, thus can improve the stability on the above-below direction of principal vibration system or Width, thus the conveying form of transported substance can be made further to become stable.Especially, even if when improving delivery speed at the driving voltage increasing Piezoelectric Driving body, uniform delivery speed also can be obtained in the length range of transport road, and carries attitude also to become stable.

In the present invention, preferred described Reference mass body is supported by a pair vibration-proof structure respectively at the front and back position place of described throughput direction, wherein, described antirattle spring and horizontal antirattle spring are connected in series and form by vibration-proof structure described in a pair, and described horizontal antirattle spring is horizontal attitude configuration along described throughput direction and is made up of leaf spring.Thus, different leaf springs can be utilized to absorb the mutually different throughput direction vibration component of vibration shape and the vertical vibration composition of benchmark mass body respectively, therefore, by making the spring performance optimization of each leaf spring, the vibration of leaking to installation surface can be reduced further.

In this situation, be preferably provided with the base station via Reference mass body described in described vibrationproof supported by plate spring, and described base station comprises the upside brace table be connected with described antirattle spring and the downside brace table supporting described upside brace table via described horizontal antirattle spring.Thus, by utilizing antirattle spring by under the state of Reference mass body absorption of vibrations in the conveying direction, utilize horizontal antirattle spring to absorb residual faint up-down vibration, thus can reliably absorb the vibration of throughput direction and the vibration of above-below direction at steady-state.In addition, support Reference mass body by the antirattle spring utilizing occupied area little, and horizontal antirattle spring large for occupied area is arranged in base station, can space efficiency be improved thus miniaturization of the apparatus.

In this situation, described in a pair that is preferably arranged on throughput direction front and back position place, horizontal antirattle spring is contrary at throughput direction front and back position towards the closure of brace table side, described downside from described upside brace table.Thus, when because the up-down vibration and making of principal vibration system be separately positioned on throughput direction front and back position place horizontal antirattle spring towards above-below direction flexure deformation time, because the connection of each horizontal antirattle spring is towards contrary at throughput direction front and back position place, the arc-shaped track of the thus flexure deformation of each horizontal antirattle spring is at throughput direction front and back position place lateral bend towards the opposite.Therefore, the elastic deformation of the horizontal vibration spring at throughput direction front and back position place disturbs mutually, thus along with up-down vibration amplitude increase and horizontal vibration spring not easily elastic deformation, therefore, can reliably absorb faint up-down vibration, and the stability of strutting system of principal vibration system can be improved.

In the present invention, preferred described transport road is arranged on the mass body of described upside.As mentioned above, transport road can be arranged in upside mass body and downside mass body at least on any one.But, especially when transport road is arranged on upside mass body on, can in the running easily handling device or process transported substance.

In the present invention, the quality entity of preferred described Reference mass body is equal to, or greater than the quality sum of described upside mass body and described downside mass body.Because Reference mass body and upside mass body and downside mass body are in the relation of antagonistic force mutually eliminating throughput direction (direction of vibration), therefore, by making the quality sum quality entity of Reference mass body equaling upside mass body and downside mass body, the eradicating efficacy of antagonistic force can be improved.But, to be supported in installation surface by antirattle spring due to Reference mass body and to be limited, therefore, by making the quality of Reference mass body be greater than above-mentioned quality sum, the amplitude of Reference mass body can be suppressed, the amplitude of upside mass body and downside mass body can be increased simultaneously, thus, the energy of vibration flowing to installation surface can be suppressed, and sufficient carrying capacity can be guaranteed on upside mass body or downside mass body, thus more stable vibration shape can be realized.

In the present invention, the quality of preferred described upside mass body is equal with on the quality entity of described downside mass body, the center of gravity interval between described Reference mass body and described upside mass body and spring constant and the center of gravity interval between described Reference mass body and described downside mass body and spring constant equal in fact.Thus, because the inertial mass of upside mass body and downside mass body and elasticity are connected form relative to Reference mass body symmetrically structure, thus can offset torque thus reduce pitching motion further.

In the present invention, preferred described transport road is linearly, and described throughput direction is the direction along straight line.The present invention also can be applicable in following situation, that is: have using the direction rotated around regulation axis (tangential direction of axis) as the rotation oscillator of direction of vibration be arranged in the vibrating type conveyer of the spiral fashion transport road on this rotation oscillator, by the vibration of hand of rotation along spiral fashion transport road conveying transported substance.But, when linearly carrying transported substance along linear conveyance path, as shown in following embodiment, can simplification device structure, and can easily improve delivery speed or make feed status become stable.

(invention effect)

[the second embodiment]

(a) in Fig. 8 is the section-drawing representing Piezoelectric Driving body 16a, the 16b of above-mentioned first embodiment, upside connecting portion 12AaS, 12AbS and lower connection part 12BaS, 12BbS, and (b) in Fig. 8 is the section-drawing representing Piezoelectric Driving body 16a ", 16b ", the upside connecting portion 12AaS ", 12AbS " of the second embodiment and lower connection part 12BaS ", 12BbS ".

In this second embodiment, in the same manner as the first embodiment, the elastic base plate 16s of Piezoelectric Driving body 16a ", 16b " " be also configured to: in the scope being formed with piezoelectrics 16p, the thickness at (above-mentioned upside Piezoelectric Driving portion 16au, 16bu and Piezoelectric Driving portion, downside 16ad, 16bd) place is large, and the thickness of the upper section forming upside amplification spring 17a ", 17b " and the lower portion office that forms downside amplification spring 18a ", 18b " is little.

But, in this second embodiment, elastic base plate 16s relative to above-mentioned upside Piezoelectric Driving portion 16au, 16bu and 16ad, 16bd place of Piezoelectric Driving portion, downside " thickness range; the thickness range at above-mentioned upside amplification spring 17a ", 17b " and above-mentioned downside amplification spring 18a ", 18b " place departs from the size of δ ts part towards throughput direction D rear side, this point is different from the first embodiment.

In the example in the figures, the surface of the throughput direction D rear side of above-mentioned upside amplification spring 17a ", 17b " and downside amplification spring 18a ", 18b ", directly makes the surface along orthogonal face of the throughput direction D rear side of above-mentioned upside Piezoelectric Driving portion 16au, 16bu and Piezoelectric Driving portion, downside 16ad, 16bd flatly extend and is formed.On the other hand, the surface of the throughput direction D front side of above-mentioned upside amplification spring 17a ", 17b " and above-mentioned downside amplification spring 18a ", 18b ", compares the surface of throughput direction D front side of above-mentioned upside Piezoelectric Driving portion 16au, 16bu and Piezoelectric Driving portion, downside 16ad, 16bd and the rear side towards throughput direction D significantly retreats.

In this embodiment, " side is the mode of taper, and the bearing of trend along upside amplification spring 17a ", 17b " and downside amplification spring 18a ", 18b " gradually changes for elastic base plate 16s in the borderline region of the borderline region of upside Piezoelectric Driving portion 16au, 16bu and upside amplification spring 17a ", 17b " and downside Piezoelectric Driving portion 16ad, 16bd and downside amplification spring 18a ", 18b " " section shape be also configured to: its thickness is with towards upside amplification spring 17a ", 17b " and downside amplification spring 18a ", 18b.

Especially be configured to as shown in illustrative example: the contour shape of the throughput direction D front side of the section of above-mentioned borderline region is configured to concave curve shape along above-mentioned bearing of trend, thus restrain smoothly on the outline line of the side, throughput direction D front of the section of upside amplification spring 17a ", 17b " and downside amplification spring 18a ", 18b ".

In this case, to offset the distance of the deviation δ ts part of above-mentioned thickness range due to above-mentioned fixed position 12Ap ", 12Bp " towards throughput direction D rear side, thus above-mentioned angle of throw θ " can be set greater than the angle of the first embodiment.In addition, in this Piezoelectric Driving body 16a ", 16b ", even if do not arranging above-mentioned upside connecting portion 12AaS, 12AbS illustrated in the first embodiment and lower connection part 12BaS, 12BbS, and when upside amplification spring 17a ", 17b " and downside amplification spring 18a ", 18b " is connected directly between on the mass body 12A and downside mass body 12B of upside, the angle of throw θ that also can be obtained to a certain degree by the deviation δ ts of above-mentioned thickness range.

[item relevant to all embodiments]

In addition, usually by angle of throw θ, θ of above-mentioned upside vibrating spring 14a, 14b and downside vibrating spring 15a, 15b ', θ " absolute value (being especially provided with the angle of the direction of vibration BVs of the upside mass body 12A of transport road 12t) be set to the angle value relative to horizontal direction within the scope of 1 degree ~ 10 degree; preferably in the scope of 2 degree ~ 8 degree, preferably in the scope of 3 degree ~ 6 degree.

In addition, upside vibrating spring 14a and the downside vibrating spring 15a of throughput direction D front side can be configured to, with the upside vibrating spring 14b of throughput direction D rear side and downside vibrating spring 15b, there is identical angle of throw, but, reach best from the viewpoint of the distribution of the vibration shape made in transport road 12t length range and vibration, also can according to the structure being the body vibration system of representative with the shape of transfer block 12Au or structure etc., by the upside vibrating spring 14a before and after throughput direction D and downside vibrating spring 15a, be set as different with the angle of throw of upside vibrating spring 14b and downside vibrating spring 15b.

Such as, when according to this device and the position relationship being connected to the front of its throughput direction D or other devices at rear, when making transfer block 12Au be greater than the overhang towards throughput direction D rear side towards the overhang of throughput direction D front side, cause actual vibration angle to change along the throughput direction D of transport road 12t because of the weight balancing of upside mass body 12A sometimes, thus make carrying capacity become uneven.Now, by the front and back position place at throughput direction D, above-mentioned angle of throw is set as different angles, thus the delivery speed along throughput direction D on transport road 12t can be adjusted.

But, non-essentially delivery speed is adjusted to even along throughput direction D, also there is the situation changing delivery speed along throughput direction D.Such as, also can be configured to: when being provided with according to when carrying the quality etc. of attitude or transported substance quality that a part of transported substance is got rid of such transported substance sorting unit from transport road 12t at the midway location of transport road 12t, by making delivery speed reduce gradually towards downstream along with the upstream side from transport road 12t, thus the conveying density on throughput direction can be made to become evenly.In addition, also separately can adjust according to above-mentioned various situation and be positioned at the upside vibrating spring 14a at throughput direction D anterior position place and the angle of throw of downside vibrating spring 15a and be positioned at the upside vibrating spring 14b at throughput direction D rear position place and the angle of throw of downside vibrating spring 15b.

On the other hand, as mentioned above, the angle of throw of upside vibrating spring 14a, 14b is set to towards direction contrary up and down with the angle of throw of downside vibrating spring 15a, 15b.In this case, the angle of throw that both can be configured to upside vibrating spring 14a, 14b is identical with the absolute value of the angle of throw of downside vibrating spring 15a, 15b, and the angle of throw that also can be configured to upside vibrating spring 14a, 14b is different from the absolute value of the angle of throw of downside vibrating spring 15a, 15b.Such as, become stable to make the feed status of the transported substance on transport road 12t or the spillage of vibration is reduced to minimum, preferably according to gravity for the impact of upside mass body 12A and downside mass body 12B or of poor quality etc., the separately angle of throw of adjustment upside vibrating spring 14a, 14b and the angle of throw of downside vibrating spring 15a, 15b.

Then, with reference to Fig. 9, the structure of base station 2 general in the respective embodiments described above is described in detail.As mentioned above, this base station 2 comprises separated upside brace table 2A and downside brace table 2B, and between upside brace table 2A and downside brace table 2B, be provided with horizontal antirattle spring 13ah, 13bh, thus form the vibration-proof structure of the vibration easily absorbing above-below direction.Horizontal antirattle spring 13ah, 13bh are the tabular leaf springs being set to the horizontal attitude extended along throughput direction D.At this, horizontal antirattle spring 13ah, 13bh are the parts of the defect in the formation for making up above-mentioned antirattle spring 13a, 13b, that is, antirattle spring 13a, 13b easily absorbs the vibration on throughput direction D but has the defect in the formation of the vibration not easily absorbing above-below direction.

Be arranged on the horizontal antirattle spring 13ah at the anterior position place of throughput direction D, the combination of the pair of bolts 21Aa configured by broad ways and packing ring 22Aa and being fixed on the installed in front portion 2Aa of above-mentioned upside brace table 2A.In addition, the installed in front portion 2Ba of above-mentioned downside brace table 2B has broad ways and to extend and in zonally outstanding smooth upper surface, horizontal antirattle spring 13ah by bolt 21Ba to be fixed on from the state of top close contact on this installed in front portion 2Ba.

On the other hand, be arranged on the horizontal antirattle spring 13bh at the rear position place of throughput direction D, the combination of the pair of bolts 21Ab configured by broad ways and packing ring 22Ab and being fixed on the rear side installation portion 2Ab of above-mentioned upside brace table 2A.In addition, the rear side installation portion 2Bb of above-mentioned downside brace table 2B has broad ways and to extend and in zonally outstanding smooth upper surface, horizontal antirattle spring 13bh by bolt 21Bb to be fixed on rear side of this on installation portion 2Bb from the state of top close contact.

In addition, on the brace table 2A of upside, be provided with bolt resettlement section 2Aaq, 2Abq of opening at least downward.Bolt resettlement section 2Aaq accommodates above-mentioned bolt 21Ba with the state do not abutted mutually, and bolt resettlement section 2Abq accommodates above-mentioned bolt 21Bb with the state do not abutted mutually.Similarly, on the brace table 2B of downside, be provided with bolt resettlement section 2Baq, 2Bbq of opening at least upward.Bolt resettlement section 2Baq accommodates above-mentioned bolt 21Aa with the state do not abutted mutually, and bolt resettlement section 2Bbq accommodates above-mentioned bolt 21Ab with the state do not abutted mutually.

In the example in the figures, above-mentioned bolt resettlement section 2Aaq, 2Abq, 2Baq, 2Bbq is formed through hole respectively on upside brace table 2A or downside brace table 2B.But, as long as each bolt resettlement section can be the structure that contactless state accommodates each bolt in the mode do not abutted mutually with each corresponding bolt, be not limited to above-mentioned through hole, such as, lid etc. also can be used to be blocked the opposition side of opening.

In base station 2 as constructed as above, by arranging above-mentioned each bolt resettlement section, even if reduce the interval between the brace table 2A and downside brace table 2B of upside, be fastened on bolt head on a brace table etc. and also can not abut (contact) with another brace table for the fixed sturcture of fixing horizontal antirattle spring, thus can reduce the height of base station 2.In addition, due to can reduce between the brace table 2A and downside brace table 2B of upside between the upper and lower every, thus can suppress to cause upside brace table 2A to tilt because of the flexure of horizontal antirattle spring 13ah, 13bh.

And then in the present embodiment, horizontal antirattle spring 13ah with 13bh is connected upside brace table 2A and downside brace table 2B along throughput direction D.Thus, principal vibration system is not easily rocked in the direction of the width, and the conveying attitude of transported substance thus can be made to become stable.Especially, when observing from throughput direction D, the installation of horizontal antirattle spring 13ah and 13bh is towards the opposite.Namely, the fixed position of horizontal antirattle spring 13ah on the brace table 2A of upside is positioned at the front of throughput direction D for its fixed position on the brace table 2B of downside, in contrast, the fixed position of horizontal antirattle spring 13bh on the brace table 2A of upside is positioned at the rear of throughput direction D for its fixed position on the brace table 2B of downside.

Thus, following elastic deformation characteristic can be obtained, that is: when the upside brace table 2A supporting above-mentioned principal vibration system via antirattle spring 13a, 13b carries out up-down vibration on the brace table 2B of downside, because the bending direction of arc-shaped track during elastic deformation is different at the front and back position place of throughput direction D, thus horizontal antirattle spring 13ah and 13bh can disturb mutually, thus becomes not easily elastic deformation tempestuously along with the amplitude increase of up-down vibration.Therefore, it is possible to the faint up-down vibration that absorption exciting agency itself produces because of disturbance force, but principal vibration system can not be caused to become unstable, thus can prevent principal vibration system from producing significantly up-down vibration or pitching motion.

In addition, as long as when vibration-proof structure only can absorb the vibration of throughput direction D, also can antirattle spring 13a, 13b be set directly in installation surface or be connected to not there is horizontal antirattle spring 13ah, 13bh base station on, thus be configured to the vibration-proof structure of resilient mounting principal vibration system only to have a pair antirattle spring 13a, 13b being positioned at throughput direction D front and back position place.Especially driving frequency is when below 500Hz, and faint up-down vibration can not throw into question substantially, therefore, as long as the absorption of vibrations on the throughput direction D of principal vibration system just can be reached vibrationproof object.

In addition, in the above-mentioned compound vibration-proof structure with a pair antirattle spring 13a, 13b and a pair horizontal antirattle spring 13ah, 13bh, as long as above-mentioned antirattle spring and horizontal antirattle spring are connected in series between principal vibration system and installation surface, just can realize absorbing the vibration on throughput direction D and this basic function of up-down vibration.Such as, also can be configured to: upside brace table 2A be divided into two parts and be configured in the front and back position place of throughput direction D respectively, thus sentence at the front and back position of throughput direction D the state configuration be separated from each other and there is the vibration-proof structure portion of above-mentioned antirattle spring 13a and horizontal antirattle spring 13ah and there is the vibration-proof structure portion of above-mentioned antirattle spring 13b and horizontal antirattle spring 13bh.

In addition, horizontal antirattle spring 13ah, 13bh are relative to the aspect of the fixed area of upside brace table 2A, circle is formed respectively two positions by above-mentioned two packing rings 22Aa, 22Ab, horizontal antirattle spring 13ah, 13bh, relative to the aspect of the fixed area of downside brace table 2B, are formed band shape respectively according to the upper surface shape of above-mentioned installed in front portion 2Ba and rear side installation portion 2Bb.But the aspect of these fixed area suitably can adjust according to the elastic deformation characteristic required by horizontal antirattle spring 13ah, 13bh.

In addition, in this manual, even if can think when upside vibrating spring is different from above-mentioned leaf spring with the spring structure of downside vibrating spring, on the upside of this vibrating spring and downside vibrating spring be also equivalent to relative to the leaning angle of vertical surface value with by the above-mentioned leaf spring identical with the angle of throw that downside vibrating spring obtains of vibrating spring on the upside of this, therefore, the meaning of this term of leaning angle used is identical with above-mentioned angle of throw.

In the present embodiment, upside angle of throw θ au, θ bu are all configured to: to produce towards throughput direction D front side obliquely, towards throughput direction D rear side direction of vibration BVs obliquely.In addition, downside angle of throw θ ad, θ bd are all configured to: to produce towards throughput direction D front side obliquely, towards throughput direction D rear side direction of vibration BVt obliquely.At this, in each embodiment, disturbance force Fau, Fbu and disturbance force Fad, Fbd is synchronously applied along throughput direction D by Piezoelectric Driving body 16a, 16b of forming homophase exciting agency, wherein, disturbance force Fau, Fbu put between Reference mass body 11 and upside mass body 12A, and disturbance force Fad, Fbd put between Reference mass body 11 and downside mass body 12B.

In this situation, can be configured to: only the disturbance force that any for front and back position side applies is set to the additional power of being forced to, and without the need to as shown in the figure disturbance force Fau, Fad of applying respectively at throughput direction D front and back position place and disturbance force Fbu, Fbd being set to the additional power of being forced to of Forced Vibration System, or, also can be configured to: all non-additional power of being forced to of disturbance force of above-mentioned both sides, but apply the additional power of being forced to by other exciting agencies be provided separately with upside vibrating spring 14a, 14b and downside vibrating spring 15a, 15b to principal vibration system.

By formation like this, because upside mass body 12A and downside mass body 12B synchronously vibrates along throughput direction D relative to Reference mass body 11, therefore, the torque that upside mass body 12A applies Reference mass body 11 and downside mass body 12B weaken mutually to the torque that Reference mass body 11 applies, thus principal vibration entire system can be suppressed in the luffing of the forms such as the swing of throughput direction D.

In addition, in each embodiment, because the direction of vibration BVs of upside mass body 12A all tilts towards direction contrary up and down with the direction of vibration BVt of downside mass body 12B, therefore, it is possible to suppress principal vibration entire system up-down vibration.Thus, in each embodiment, because above-mentioned luffing or up-down vibration are inhibited, the feed status of transported substance thus can be made to become stable or reduce the vibration of leaking towards installation surface.Especially, consider that the impact that above-mentioned luffing or up-down vibration cause for transported substance or outside along with the propelling of high frequency increases, thus can think extremely effective for the reply aspect of the high frequency of conveying vibration in recent years or the increase of delivery speed etc.

[the 5th embodiment]

Figure 13 is the sketch of the principal vibration system architecture representing the 5th embodiment.In the 5th embodiment, by upside amplification spring 37a, 37b and downside amplification spring 38a, 38b and Piezoelectric Driving body 36a, 36b is separately formed, and by Piezoelectric Driving body 36a, 36b and upside amplification spring 37a, 37b and lower amplification spring 38a, 38b is set to the perpendicular attitude being parallel to the vertical surface vertical with throughput direction D respectively, and, utilize bolt and packing ring etc. and via the distance piece 39au on throughput direction D with thickness, 39bu, 39ad, 39bd and connect Piezoelectric Driving body 36a, the upper end of 36b and upside amplification spring 37a, the bottom of 37b, and Piezoelectric Driving body 36a, the bottom of 36b and downside amplification spring 38a, the upper end of 38b.

When so forming, upside vibrating spring 34a, the fixed position 11p of 34b on Reference mass body 11 and upside vibrating spring 34a, the connection lead (long and two-short dash line in figure) of the fixed position 12Ap of 34b on the mass body 12A of upside tilts, and, downside vibrating spring 35a, the fixed position 11p of 35b on Reference mass body 11 and downside vibrating spring 35a, the connection lead (long and two-short dash line in figure) of the fixed position 12Bp of 35b on the mass body 12B of downside tilts, wherein, above-mentioned upside vibrating spring 34a, 34b is by Piezoelectric Driving portion, upside 36au, 36bu and upside amplification spring 37a, 37b is formed, downside vibrating spring 35a, 35b is by Piezoelectric Driving portion, downside 36ad, 36bd and downside amplification spring 38a, 38b is formed.Therefore, it is possible to set upside vibrating spring 34a, 34b and the above-mentioned angle of throw θ au of downside vibrating spring 35a, 35b, θ bu, θ ad, θ bd in the same manner as above-mentioned embodiment.

In this situation, by changing the thickness of distance piece 39au, 39bu, 39ad, 39bd on throughput direction D, easily can adjust above-mentioned angle of throw θ au, θ bu, θ ad, θ bd.At this, the lower end of upside amplification spring 37a, 37b and the upper end of downside amplification spring 38a, 38b, be fixed in the upside connection structure of Piezoelectric Driving portion, upside 36au, 36bu and the downside connection structure of Piezoelectric Driving portion, downside 36ad, 36bd with the stateful connection of the rear side overlap from throughput direction D respectively.Thus, no matter whether be provided with distance piece, all can obtain angle of throw to a certain degree.

In addition, in each embodiment discussed above, use Piezoelectric Driving body 16a, 16b, 26a, 26b, 36a, 36b that upside Piezoelectric Driving portion 16au, 16bu, 26au, 26bu, 36au, 36bu and Piezoelectric Driving portion, downside 16ad, 16bd, 26ad, 26bd, 36ad, 36bd are formed in one.But Piezoelectric Driving body also can be configured to: Piezoelectric Driving portion, upside and Piezoelectric Driving portion, downside are made up of different Piezoelectric Driving bodies respectively, and this different Piezoelectric Driving body is combined on Reference mass body 11 respectively.In addition, it is one with the part be formed in Piezoelectric Driving portion, downside that piezoelectrics on elastic base plate are configured to the part be formed in Piezoelectric Driving portion, upside, but, also can be configured to: separately form the part in Piezoelectric Driving portion, upside and the part in Piezoelectric Driving portion, downside, thus piezoelectrics are separated from each other.

[action effect of each embodiment]

In the principal vibration system of each embodiment discussed above, from throughput direction D, the vibration phase of Reference mass body 11 is contrary with the vibration phase of upside mass body 12A and downside mass body 12B (phase difference is 180 degree).Therefore, when considering for benchmark with base station 2, the antagonistic force of the throughput direction D produced by the vibration of Reference mass body 11, total antagonistic force of producing with the vibration by upside mass body 12A and downside mass body 12B are in the mutual relation (relation offset or weaken) eliminated.Thereby, it is possible to reduce the vibration of the throughput direction D being transmitted to base station 2 side via antirattle spring 13a, 13b.

On the other hand, when considering for benchmark with Reference mass body 11, the antagonistic force that upside mass body 12A applies and the antagonistic force that downside mass body 12B applies, when observing from throughput direction D, direction is all identical, but, torque mutually in the upside mass body 12A in phase vibrated is contrary with the direction of the torque of downside mass body 12B, thus in the relation (relation offset or weaken) mutually eliminated.Therefore, the antagonistic force of the hand of rotation suffered by Reference mass body 11 reduces, thus not easily produces pitching motion, and the vibration being transmitted to the above-below direction of base station 2 side via antirattle spring 13a, 13b is also reduced.In addition, by so making to become stable along the delivery speed of the transported substance of transport road 12t length direction or the feed status of conveying attitude etc.

In the present invention, in the principal vibration system shown in Figure 11, by arranging with homophase exciting agency and Piezoelectric Driving body 16a, 16b of making upside mass body 12A and downside mass body 12B apply disturbance force in the mode in phase vibrated relative to Reference mass body 11, thus make upside mass body 12A and downside mass body 12B in fact carry out action as a mass body, in other words, by homophase exciting agency, upside mass body 12A and downside mass body 12B is restricted to a mass body and carries out action.Therefore, form another mass body (upside mass body 12A and downside mass body 12B) having and be connected to a mass body on base station 2 and Reference mass body 11 via antirattle spring 13a, 13b elasticity and be connected to via these four vibrating spring elasticity of vibrating spring 14a, 14b, 15a, 15b on Reference mass body 11, and be essentially double freedom (Two DegreeOf Freedom) or two particle (Two-Mass) be forced to (decay) vibrating system.

In this vibrating system, there are height two resonance frequency ω 1 and ω 2, and, two mass bodies frequency band between these two resonance frequency ω 1 and ω 2 anti-phase vibrates mutually.

In the rp mode of vibrating system with mass body 11 and these two mass bodies of mass body 12A+12B, from throughput direction D, antagonistic force on throughput direction D between two mass bodies is in the relation mutually eliminated, and, in embodiments, as mentioned above, relative to a mass body and Reference mass body 11, another mass body is divided into upside mass body 12A and downside mass body 12B, and elasticity is connected to the opposition side of Reference mass body 11 respectively, therefore, the torque suffered by Reference mass body 11 is also in the relation mutually eliminated.

At this, with the mass M of Reference mass body 11 ₁₁center-of-gravity position when being benchmark, the torque of upside mass body 12A is long-pending, the i.e. M of its quality and center of gravity spacing _12A× R _12A, similarly, the torque of downside mass body 12B is M _12B× R _12B.But the direction of upside mass body 12A and downside mass body 12B torque is contrary.The formation of such vibrating system, can form the vibration shape substantially different from existing apparatus, and can realize the conveying form not relying on the bed knife that installation surface applies.

In existing apparatus, in order to ensure the feed status of the transported substance on transport road, base station must to be securely fixed in installation surface or to increase the weight of base station, relative to this, in the present invention, extreme, even if when not being fixed in the installation surface only lower end of antirattle spring 13a, 13b being positioned in soft bed clothes etc. or when only arranging weight-saving base station 2 and be not fixed, vibration shape also changes (deterioration) hardly, and the conveying form on transport road 12t is also almost constant.

In addition, from accompanying drawing clearly, when only considering principal vibration system, from the antagonistic force aspect offset on throughput direction D, preferably M is configured in fact ₁₁=M _12A+ M _12B, from above-mentioned two the torque aspects of counteracting, be preferably configured to M in fact _12A× R _12A=M _12B× R _12B, from minimizing pitching motion aspect, be preferably configured to M in fact _12A=M _12Band R _12A=R _12B.

Above structure and the action effect structure substantially according to Figure 11 of expression concept of the present invention obtains, in the present embodiment, above-mentioned homophase exciting agency (Piezoelectric Driving body) is respectively equipped with exciting portion, upside (Piezoelectric Driving portion, upside) and exciting portion, downside (Piezoelectric Driving portion, downside), and directly and apply disturbance force independently, thus can simplification device structure, and also can easily adjust such as tackling the frequency or amplitude etc. of the exciting side of the variation (variation) of transported substance or transport road etc.

Especially in the present embodiment, owing to being provided with upside Piezoelectric Driving portion 16au, the 16bu be included in upside vibrating spring 14a, 14b and Piezoelectric Driving portion, downside 16ad, 16bd of being included in downside vibrating spring 15a, 15b, and carry out exciting by Piezoelectric Driving mode, thus without the need to separating with vibrating system, exciting agency is set in addition, thus can simplification device structure further.

In the present embodiment, upside vibrating spring 14a, 14b are directly connected with downside vibrating spring 15a, 15b, and its point of connection is fastened on Reference mass body 11.Therefore, the antagonistic force that upside mass body 12A and downside mass body 12B applies is consistent with each other for the point of action of Reference mass body 11, therefore, can not cause producing useless vibration or useless torque because of the position deviation of the point of action of upper and lower antagonistic force.

In addition, because upside vibrating spring 14a, 14b are directly connected with downside vibrating spring 15a, 15b, thus easily between upside vibrating spring and downside vibrating spring, exchange energy of vibration, can think thus and can form more stable vibrating system.And then, in the present embodiment, by above-mentioned formation, also there is this effect of height that can reduce vibrating type conveyer 10.

In addition, the vibration shape of Figure 11 not carries out any restriction to the present invention and present embodiment, but, M _12A=M _12B, R _12A=R _12B, upside vibrating spring 14a, 14b and downside vibrating spring 15a, 15b length all identical with spring constant, the length of antirattle spring 13a with 13b is also identical with spring constant.

In the present embodiment, by using length direction middle part to be combined in one-piece type Piezoelectric Driving body 16a, 16b on Reference mass body 11, can reliably and stably disturbance force is applied to upside mass body 12A and downside mass body 12B.Especially, Piezoelectric Driving body 16a, 16b reliably can apply the disturbance force of homophases to upper and lower sides two mass body 12A and 12B by the flexure deformation of one up and down.

In addition, due in upside vibrating spring 14a, 14b and downside vibrating spring 15a, 15b, upside Piezoelectric Driving portion 16au, 16bu and Piezoelectric Driving portion, downside 16ad, 16bd are configured in Reference mass body 11 side, therefore, by being configured in upside amplification spring 17a, 17b of mass body 12A side, upside or being configured in downside amplification spring 18a, 18b of mass body 12B side, downside, enough amplitudes required when transport road 12t is set on upside mass body 12A or downside mass body 12B can be produced.

In the present embodiment, except above-mentioned action effect, by by upside vibrating spring 14a, the actual tilt angles of 14b and angle of throw θ au, θ bu is set as being formed towards throughput direction D front side direction of vibration BVs obliquely, and, by downside vibrating spring 15a, the actual tilt angles of 15b and angle of throw θ ad, θ bd is set as being formed towards throughput direction D front side direction of vibration BVt obliquely, thus can obtain based on above-mentioned angle of throw θ au on transport road 12t, the carrying capacity of θ bu, simultaneously, upside mass body 12A and downside mass body 12B can be reduced relative to the up-down vibration of Reference mass body 11 in the principal vibration system in phase vibrated.Therefore, even if when improve the frequency of vibrating system or delivery speed etc., the stabilization of conveying attitude or the uniformization of delivery speed of transported substance also can be guaranteed, and vibration can be suppressed to leak towards installation surface.

In addition, even if seldom producing in the principal vibration system of up-down vibration as mentioned above, also there is the situation that fully cannot suppress up-down vibration when improving frequency.But, in the present embodiment, configure between the upside brace table 2A and downside brace table 2B of base station 2 and arrange and horizontal antirattle spring 13ah, 13bh of being made up of leaf spring in horizontal attitude, effectively can absorb up-down vibration thus, thus can suppress to cause up-down vibration to increase because of high frequency, therefore, it is possible to make conveying attitude become stable and avoid energy of vibration to leak.

Especially, by being connected between the brace table 2A and downside brace table 2B of upside towards throughput direction D by horizontal antirattle spring 13ah and 13bh, the vibrating system be supported on the brace table 2A of upside can be made to stablize in the direction of the width.In addition, when observing from throughput direction D, the installation direction of horizontal antirattle spring 13ah and 13bh is contrary at the front and back position of throughput direction D, thus can be improved the stability of the vibrating system be supported on the brace table 2A of upside by the mutual interference effect of two springs.

At this, in the process being formed at arrangement or sorting transported substance in the transport road 12t on transfer block 12Au, utilize the eliminating mechanism that the shape of transport road 12t, jet-impingement mechanism or mechanical motion mechanism etc. are known, by the transported substance of not attitude arrangement according to the rules or because be certain reasons such as substandard products and transported substance without the need to continuing conveying is discharged from transport road 12t, and be recovered to and be configured in the above-mentioned recovery road 42t of transport road 12t side.

And, by the vibration that above-mentioned Piezoelectric Driving body 46a, 46b produce, carry towards the recovery that F is contrary the transported substance be recovered towards with above-mentioned conveying towards B being formed in the recovery road 42t in not shown recovery side transfer block, thus make its upstream side returning transport road 12t or discarded.In addition, the side plate 39 and 49 shown in Figure 16 and Figure 17 be respectively in the width direction both sides by principal vibration system with reclaim the lid that side supply unit covers.

As shown in figure 15, in present embodiment, be provided with the principal vibration system identical with Figure 13 shown device, and be provided with at the front and back position place of throughput direction D support Reference mass body 11 and have towards tabular antirattle spring 13a, the 13b in the plate face of throughput direction D.At this, in the front side portion that antirattle spring 13a, 13b are arranged on Reference mass body 11 respectively by bolt 19a, 19b and distance piece 19c, 19d and rear lateral portion.

Now, antirattle spring 13a is from being connected to the front side portion of Reference mass body 11 in the anterior position of throughput direction D via distance piece 19c relative to Piezoelectric Driving body 36a, and antirattle spring 13b is also connected in the rear lateral portion of Reference mass body 11 via distance piece 19d from relative to Piezoelectric Driving body 36b in the anterior position of throughput direction D.Distance piece 19c and 19d has same thickness when observing from throughput direction D, and thus, the interval between Piezoelectric Driving body 36a and antirattle spring 13a upper end is equal with the interval between Piezoelectric Driving body 36b and antirattle spring 13b upper end.

In the present embodiment, center-of-gravity position 11g, 12Ag, 12Bg of preferred reference mass body 11, upside mass body 12A and downside mass body 12B are under static state positioned at the same position place of throughput direction D.That is, preferred above-mentioned center-of-gravity position 11g, 12Ag and 12Bg are all configured on same perpendicular line.But, under actual conditions, according to the difference of the situation before and after the condition of the setting place of vibrating type conveyer 30 or the transport path of transported substance, and require the upside mass body 12A being provided with transport road 12t to be formed as different shape, structures.Especially, overhanging (overhang) (extension elongation) before and after the throughput direction D of upside mass body 12A sets according to the apparatus structure before and after it.

In the vibrating type conveyer 30 shown in Figure 15, the length that the transfer block 12Au of upside mass body 12A stretches out towards throughput direction D front is greater than the length of stretching out towards rear, thus its center-of-gravity position 12Ag be configured in compare Reference mass body 11 center-of-gravity position 11g closer to the position in throughput direction D front.And, in order to the center-of-gravity position 11g of the center-of-gravity position 12Ag and Reference mass body 11 that tackle upside mass body 12A misplaces on throughput direction D, compared with being similarly configured in by the center-of-gravity position 12Bg of downside mass body 12B with above-mentioned center-of-gravity position 12Ag, the center-of-gravity position 11g of Reference mass body 11 is closer to the position in throughput direction D front, thus reduces and because of the antagonistic force that applies of upside mass body 12A and downside mass body 12B, Reference mass body 11 is vibrated in the vertical direction.Thus, the center-of-gravity position of principal vibration entire system be configured in compare Reference mass body 11 center-of-gravity position 11g a little near the position in throughput direction D front.

Now, the distance between the installation site of preferred antirattle spring 13a and 13b and the center-of-gravity position (not shown) of principal vibration entire system is equal respectively when observing from throughput direction D.Be configured in the example in the figures: when observing from throughput direction D, the intermediate point of the installation site of antirattle spring 13a and the installation site of antirattle spring 13b and the center-of-gravity position of principal vibration system are configured in same position place.

Figure 20 is the upside Piezoelectric Driving portion 36Au of Piezoelectric Driving body 36a and the enlarged left view of upside amplification spring 37a of the upside vibrating spring 34a forming present embodiment.In the same manner as the first embodiment, Piezoelectric Driving body 36a is provided with elastic base plate 36s and is laminated to the piezoelectrics 36p on this elastic base plate 36s, and is fixed on the front side portion of Reference mass body 11 in Width both sides by the sidepiece connection structure be arranged on elastic base plate 36s.

In addition, piezoelectrics 36p is configured between sidepiece connection structure when observing in the width direction, and the height comparing sidepiece connection structure extends, in forming between upside Piezoelectric Driving portion 36au and Piezoelectric Driving portion, downside 36ad (not shown) towards above-below direction further.Elastic base plate 36s is provided with from being formed with the region of piezoelectrics 36p further towards upper portion connecting structure 36su and the lower portion connecting structure 36sd (not shown) of above-below direction extension.In addition, downside Piezoelectric Driving portion 36ad is configured to Piezoelectric Driving portion, upside 36au: relative to being connected the Width horizon 36o of sidepiece connection structure of Width both sides in upper and lower symmetry, in addition, the structure of Piezoelectric Driving body 36b is identical with Piezoelectric Driving body 36a, therefore omits the explanation about Piezoelectric Driving body 36b.

Piezoelectric Driving portion, the upside 36au of present embodiment is fastened on the amplification spring 37a of upside via distance piece 39s by bolt 39t etc.Now, the lower end of upside amplification spring 37a is fixed on the upside connection structure 36su of upside Piezoelectric Driving portion 36au in the mode of the rear overlap from throughput direction D via distance piece 39s.Be configured to thus: from throughput direction D, the line of centers 37x of the line of centers 36x of the thickness direction of Piezoelectric Driving body 36a and the thickness direction of upside amplification spring 37a is configured in the position of mutually staggering.By making this line of centers 36x and 37x mutually stagger, thus set the angle of throw θ of upside vibrating spring 34a relative to upside mass body 12A (contiguous block 12Ad) in the same manner as Figure 13.In the present embodiment, above-mentioned angle of throw θ can be adjusted according to the change of the presence or absence of distance piece 39s or thickness.

As shown in the figure on right side in Figure 20, in use entirety, there is uniform thickness t _oelastic base plate 36s ' time, the interval between the line of centers 36x of Piezoelectric Driving body 36a ' and the line of centers 37x of upside amplification spring 37a becomes 0.5 (t _o+ t ₁)+ts.Wherein, t ₁for the thickness of upside amplification spring 37a, ts is the thickness of distance piece 39s.Now, actual angle of throw θ ' is the leaning angle of connection lead relative to perpendicular line of horizon 36o ' and the point of connection of upside amplification spring 37a and upside mass body 12A when observing from throughput direction D.But, as in the embodiment described in, when the driving frequency of Piezoelectric Driving body 36a ' improves, due to the thickness t of elastic base plate 36s ' _oincrease, thus angle of throw θ ' becomes excessive, cause the above-below direction composition of the vibration of upside mass body 12A increase and make the transported substance bob on transport road 12t thus, thus likely cause the conveying attitude of transported substance or delivery speed instability or delivery speed entirety to reduce.

In addition, usually when oscillation frequency increases, angle of throw when being less than low oscillation frequency by making angle of throw θ, the stability of the stability of vibrating system and the conveying attitude of transported substance can be improved, thus raising transport efficiency, therefore, delivery speed also increases from the results of view.Therefore, in the present embodiment, reduce the thickness range of the upside connection structure 36su of elastic base plate 36s towards throughput direction D front, thus angle of throw θ can be set as smaller angle.In the example in the figures, with the surface configuration being positioned at throughput direction D rear side of upside connection structure 36su compare lamination have the part of piezoelectrics 36p towards throughput direction D front side skew (t _o-t ₂) the mode of position be configured to stepped, thus make the thickness t of upside connection structure 36su ₂be less than above-mentioned thickness t _o.

Thus, the side-play amount of line of centers 36x and 37x on throughput direction D becomes (t ₂-0.5t _o+ 0.5t ₁+ ts), compare above-mentioned interval 0.5 (t _o+ t ₁)+ts reduces (t _o-t ₂).In this situation, also preferably the lamination of Piezoelectric Driving body 36a has the section shape (being the surface of the rear side (on the left of illustrate) of throughput direction D in graphic example) of the part of piezoelectrics 36p and the boundary member of upside connection structure 36su, has along with towards upside connection structure 36su, thickness gradually changes (reduction) thus along the concave curve shape profile of smooth surface convergence.

In the present embodiment, in the same manner as the 5th embodiment, upside amplification spring 37a, 37b and downside amplification spring 38a, 38b, be fixed in the upside connection structure of Piezoelectric Driving portion, upside 36au, 36bu and the downside connection structure of Piezoelectric Driving portion, downside 36ad, 36bd with the stateful connection of the rear side overlap from throughput direction D respectively.Thus, no matter whether there is distance piece, angle of throw to a certain degree can be obtained.

In addition, by by Piezoelectric Driving portion, upside 36au, the upside connection structure of 36bu and Piezoelectric Driving portion, downside 36ad, the downside connection structure of 36bd is configured to its thickness and is less than the part that lamination has piezoelectrics 36p, thus the top of the bottom of connection structure on the upside of this and downside connection structure (having piezoelectrics 36p part side not by part that bolt and packing ring etc. are fixing at lamination) can be configured to and upside amplification spring 37a, 37b and downside amplification spring 38a, 38b together plays a role as the part playing the effect increasing the flexure deformation that piezoelectrics 36p produces, therefore, upside amplification spring 37a can be shortened, 37b and downside amplification spring 38a, the length of 38b, thus the height of device entirety can be reduced.

By manufacturing experimently the vibrating type conveyer 30 of present embodiment and actually driving, thus measure the vibrational state of transfer block 12Au and observed the feed status of transported substance.In trial-production device, the quality of the upside mass body 12A shown in Figure 15 is 620g, the height of center-of-gravity position 12Ag is 110mm, the quality of Reference mass body 11 is 1230g, the height of center-of-gravity position 11g is 67mm, the quality of downside mass body 12B is 720g, the height of center-of-gravity position 12Bg is 27.5mm, in addition, relative to the center-of-gravity position 11g of Reference mass body 11, the center-of-gravity position 12Ag of upside mass body 12A is positioned at the position of the skew 9.8mm towards conveying towards F side, the center-of-gravity position 12Bg of downside mass body 12B is positioned at the position of the skew 1.5mm towards conveying towards F side.Upside vibrating spring 34a, 34b and downside vibrating spring 35a, 35b all with 3.24 degree for benchmark adjusts, thus uniform delivery speed can be obtained along transport road 12t.

This trial-production device is made to carry out work with the 343.4Hz of a little higher than resonance frequency, utilize laser displacement gauge measurement be provided with amplitude on the throughput direction D of the transfer block 12Au of transport road 12t (amplitude at the actual exit end 12to place for transport road 12t) and set it to 0.105mm, and the rectangular-shaped electronics package of to be 0.6mm, height and width using length be 0.3mm is carried as transported substance.Now, laser displacement gauge is utilized to measure the diagram P of transfer block 12Au ₁~ P ₄the amplitude of the above-below direction at each position and diagram P ₅~ P ₇the Width amplitude at each position.Consequently, in this trial-production device, delivery speed is 3.8m/min, the aviation value of above-below direction amplitude is 0.0085mm, the aviation value of Width amplitude is 0.0083mm, in the length range of transport road 12t, obtain uniform delivery speed, and transported substance beat or attitudes vibration also few.

In addition, when can carry swimmingly increase driving voltage in the scope of transported substance time, delivery speed is maximum rises to 10m/min, the amplitude of throughput direction is now 0.26mm, the aviation value of above-below direction amplitude is 0.02mm, and the aviation value of Width amplitude is 0.012mm, does not have problems.Especially, even if the attitude of transported substance also keeps stable, above-mentioned each position P when improving delivery speed ₁~ P ₇the deviation of the amplitude at place is also little, and the homogeneity along the delivery speed of transport road 12t is also high.
