Abstract
A vibratory mechanism which is composed of vibratory shafts, which are stored within a roll and are arranged symmetrically across a rotation axis of the roll, a fixed eccentric weight fixed to respective vibratory shafts, a rotatable eccentric weight rotatably attached to respective vibratory shafts, a rotation controller controlling a range of movement of the rotatable eccentric weight, and an eccentric moment controller which changes an eccentric moment around the vibratory shaft depending on the rotation direction of the vibratory shafts, whereby the vibration state of the roll is switchable between standard vibration and horizontal vibration.

A vibratory mechanism comprising:
- vibratory shafts, which are stored within a roll and are arranged symmetrically across a rotation axis of the roll;
- a fixed eccentric weight fixed to respective vibratory shafts;
- a rotatable eccentric weight rotatably attached to respective vibratory shafts;
- a rotation controller controlling a range of movement of the rotatable eccentric weight;
- and
- an eccentric moment controller which changes an eccentric moment around the vibratory shaft depending on a rotation direction of the vibratory shafts,
- whereby the roll vibrates in all radial directions when respective vibratory shafts rotate in one direction, and the roll vibrates in a direction tangential to the circumference of the roll when respective vibratory shafts rotate in reverse direction.
A vibratory mechanism comprising:
- a first vibratory shaft and a second vibratory shaft, which are stored within a roll and are arranged symmetrically across a rotation axis of the roll;
- a first fixed eccentric weight and a second fixed eccentric weight, which are fixed to the first vibratory shaft and the second vibratory shaft, respectively;
- a first rotatable eccentric weight and a second rotatable eccentric weight, which are rotatably attached to the first vibratory shaft and the second vibratory shaft, respectively;
- a first rotation controller, which is provided on the first fixed eccentric weight and controls a first phase difference between the first fixed eccentric weight and the first rotatable eccentric weight depending on the rotation direction of the first vibratory shaft;
- a second rotation controller, which is provided on the second fixed eccentric weight and controls a second phase difference between the second fixed eccentric weight and the second rotatable eccentric weight depending on the rotation direction of the second vibratory shaft.
