摘要:
A levitation system is disclosed. The levitation system comprises at least one levitation device having a horizontal flexible tapered member physically coupled to a vibration actuator via a vertical flexible rod, wherein a widest surface of the tapered member is responsive to a vibration of the actuator by exhibiting a three-dimensional deformation.

The invention relates to a supply device (1) for a screening machine (2), having a conveying channel (10) with a channel bottom (11), a feed region (15) and an ejection edge (14), and also a vibration transducer system (20) coupled to the conveying channel (10). The supply device (1) is characterized in that vibrations of the conveying channel (10) that are induced by the vibration transducer system (20) have components in the longitudinal direction (x) and in the transverse direction (y) of the channel bottom (11) and also in a direction (z) perpendicular to the channel bottom (11), wherein the components are phase-shifted with respect to one another in the longitudinal direction (x) and transverse direction (y).

A vibratory conveyor is provided which comprises a machine frame, a twoarmed lever mounted on the frame for pivotal movement about an axis, a reaction base mounted on one arm of the lever, and a conveyor element for conveying a product from one end to the other. Leaf springs are connected between the conveyor element and the reaction base and arranged to vibrate so as to cause the conveyor element to convey product. A sensor is disposed between the said one arm and the machine frame for sensing the weight of product on the conveyor element. The lever and conveyor element are so arranged that a line connecting the axis of pivotal movement of the lever and the centre of mass of the conveyor element runs perpendicular to the length of the leaf springs.

An orbital vibrator (12) comprises a rotatable shaft (14) with a crank (28) attached thereto, a bearing (31) mounted on said crank, a reaction mass (30) mounted on said crank by means of said bearing and, by virtue of said mounting, orbitally oscillating about said crank in response to the rotation of said shaft in order to induce avibratory motion.
摘要:
Disclosed is an automatic tablet feeding apparatus. The automatic tablet feeding apparatus includes a guide duct having a receiving space defined therein to receive tablets introduced thereinto and guide the tablets downward, a slider formed to be inclined downward toward the receiving space, a first vibrator accommodated in an outer side portion of the slider and configured to output vibration energy in response to an external control signal, a vibrator controller configured to control the frequency of the first vibrator, and an elastic support plate received in an outer side surface of the slider. The vibrator controller includes a smoothing circuit unit smoothing a DC voltage, a main controller generating a PWM control signal, and a voltage variable switching unit varying the DC voltage smoothed by the smoothing circuit unit in response to the PWM control signal from the main controller and applying the DC voltage to the first vibrator.
