Vibratory conveying apparatus

Abstract

A vibratory conveying apparatus provided by the invention effectively restrains vibratory energy which is flowed out from the apparatus to the setting. The vibratory conveying apparatus (10) of the invention is provided with the following components: a conveying member (11) which is provided with a linear conveying path for conveying the conveyed object; plate-shaped first elastomers (12a,12b) which elastically support the conveying member in a manner that flexible deformation in the conveying direction is allowed; connecting components (13a,13b) which are connected with the lower part of the conveying member through the first elastomer; second elastomers (14a,14b) which respectively support the connecting component from the lower part at the front part and the back part in the conveying direction; exciting members (16a,16b) which endows vibration in the conveying direction to the connecting component; plate-shaped third elastomers (21a,21b) which are connected with the connecting component in a manner that flexbile deformation in the conveying direction is allowed; and an inertia mass member (22) which is elastically connected with the connecting component through the third elastomers and can move in the conveying direction. The conveying member and the inertia mass member vibrate in opposite phases.

Description

technical field [0001] The present invention relates to a vibrating conveying device, and more particularly, to a structure of a conveying device that vibrates a conveying body having a conveying path for conveying objects and includes an inertial mass body that vibrates in a phase opposite to the conveying body. Background technique [0002] Generally, in a vibrating conveying device, it is known to provide an inertial mass body ( Counterweight) device (for example, refer to the following patent documents 1 and 2). In the device described in Patent Document 1, the inertial mass body 22 is connected and fixed to the side opposite to the side where the vibration is transmitted to the conveying body 25 with respect to the vibration excitation body 21, and the vibration excitation body mounting member 23 is connected to the vibration excitation body 21. The middle portion of the vibration-transmitting leaf spring 26 of the conveying body 25 is elastically supported by the vibr...

Problems solved by technology

[0011] However, in the existing vibrating conveying device like the above-mentioned patent document 1, since the inertial mass body 22 is directly connected to the side opposite to the excitation body mounting part 23 with respect to the vibrating body 21, the inertial mass body 22 and the vibrating body Vibration occurs between the exciter mounting parts 23, so there is the following problem: the overall vibration form of the vibrating body 21, the inertial mass body 22, and the vibrating body mounting parts 23 for resisting the inertial force of the conveying body 25 is difficult to be consistent with the conveying body. The vibration form of the body 25 is sufficiently corresponding, and the reaction force of the conveying body 25 cannot be sufficiently absorbed, and the vibration energy transmitted from the middle part of the vibration transmission leaf spring 26 to the connecting member supporting piece 28 cannot be largely suppressed.

In addition, in this structure, there is also the following problem: it is easy to generate vibration along the conveying direction on the whole of the exciter 21, the inertial mass body 22, the exciter mounting member 23, the conveying body 25, and the leaf spring 26 for vibration transmission. Up and down movement (pitching movement), the vibration energy of this up and down movement tends to flow out to the connecting member support piece 28 side, and causes the unevenness of the conveying speed in the conveying direction of the conveying body 25 or the instability of the conveying state of the conveying object.

[0012] In addition, in the conventional vibrating conveyor like Patent Document 2, since the vibrating bodies 20a, 20b directly drive the groove 11, it is difficult to prevent the reaction from being transmitted from the plate spring mounting body 14 to the plate spring 15 for anti-vibration. , In addition, in order to obtain a sufficient anti-vibration effect, it is necessary to interpose other exciters 21a, 21b between the leaf spring mounting body 14 and the counterweight 13, and detect The above-mentioned other exciters 21a, 21b are controlled based on the detection value of the device 22, so there is a problem that the mechanical structure and the control of the exciters are complicated.

In addition, in this structure, although it is possible to cancel the reaction in the conveying direction through the control between the pair of vibrators, it is difficult to suppress the vertical movement of the entire structure arranged on the anti-vibration leaf spring 15 along the conveying direction. (pitch action), so it is difficult to achieve sufficient suppression of the outflow of vibration energy and uniformity of conveying speed or stability of conveying state

[0013] Furthermore, in the conventional vibrating conveying devices such as the aforementioned Patent Documents 3 and 4, although the outflow of vibration energy to the base 1 can be suppressed to some extent, as in the aforementioned Patent Document 1, due to the piezoelectric The inertial body 6 is connected to the opposite side of the driving body 3, and the effect of reducing the reaction force of the conveying body 2 by the inertial force of the inertial body 6 may not be sufficient.

In addition, when the mass of the inertial body 6 is increased, the connection member 4 connected to the front and rear sides of the inertial body 6 via the piezoelectric driving body and the conveying body 2 connected to the connection member 4 via the amplifying spring 5 are likely to be damaged. Up and down movement along the conveying direction (pitch motion), so there are actually problems related to the uniformity of the conveying speed or the stability of the conveying state, such as the conveying speed fluctuates along the conveying direction or the light-weight conveyed objects are easily disturbed.
