Abstract
The invention relates to a method for using a SWING-type mixing device (1) and to a SWING-type mixing device (1), in which a main turning axle (2) of the mixing device is turned back and forth, that is in turns to a first direction all the way to a first turning point (FT) and to a second direction all the way to a second turning point (ST). According to the invention, power transmission to the main turning axle (2) can be produced by terminating power transmission to one direction slightly before the turning point, by letting mass inertia of the apparatus handle the turning of the direction of movement at the turning point and by starting power transmission to the opposite direction of the first slightly after the turning point.
Claims15
A method for using a SWING-type mixing device, the method comprising:
- turning a main turning axle of the mixing device back and forth around its axis, that is in turns to a first direction all the way to a first turning point and to a second direction all the way to a second turning point for getting other turning axes fixed to the main turning axle and a container of mixable substance into a SWING-type movement;
- wherein by
- monitoring the turning of the main turning axle by one or several sensors;
- turning the main turning axle back and forth around its axis in accordance with the following steps a)-d):
- a) subjecting the main turning axle to a force turning it to the first direction until the sensor detects the main turning axle having turned at a certain distance from the first turning point, whereby the force turning into the first direction is terminated,
- b) allowing the main turning axle to turn to the first turning point and back therefrom by mass inertia of the mixing device until the sensor detects the main turning axle having turned at a certain distance from the first turning point;
- c) subjecting the main turning axle to a force turning it to the second direction until the sensor detects the main turning axle having turned at a certain distance from the second turning point, whereby the force turning into the second direction is terminated,
- d) allowing the main turning axle to turn to the second turning point and back therefrom by mass inertia of the mixing device until the sensor detects the main turning axle having turned at a certain distance from the second turning point.
A SWING-type mixing device, which comprises:
- a main turning axle of the mixing device arranged to be turned back and forth around its axis, that is in turns to a first direction all the way to a first turning point and to a second direction all the way to a second turning point;
- other turning axles fixed to the main turning axle;
- fixing means for fixing a container of mixable substance to one of the other turning axles;
- an actuator, which is coupled to the main turning axle by means of a power transmission means;
- wherein the SWING-type mixing device further comprises
- one or several sensors arranged to monitor the turning of the main turning axle;
- whereby the actuator is arranged to subject the main turning axle to forces turning it around its axis in accordance with the following steps a)-d):
- a) subjecting the main turning axle to a force turning it to the first direction, until the sensor detects the main turning axle having turned at a certain distance from the first turning point whereby the force turning into the first direction is terminated,
- b) allowing the main turning axle to turn to the first turning point and back therefrom by mass inertia of the mixing device until the sensor detects the main turning axle having turned at a certain distance from the first turning point;
- c) subjecting the main turning axle to a force turning it to the second direction until the sensor detects the main turning axle having turned at a certain distance from the second turning point, whereby the force turning into the second direction is terminated,
- d) allowing the main turning axle to turn to the second turning point and back therefrom by mass inertia of the mixing device until the sensor detects the main turning axle having turned at a certain distance from the second turning point.
