Abstract
A tube pump system is provided, which includes a pair of roller units which are rotated around the axis line from a contact position to a separate position in a state where the pair of roller units compress the tube, a pair of drive units which rotate the pair of roller units respectively, and a control unit which controls each of the pair of drive units, wherein the control unit controls each of the pair of drive units such that, when one of the pair of roller units passes the separate position, an angular velocity of the other of the pair of roller units toward the separate position is gradually decreased.

A tube pump system comprising:
- a housing unit which has an inner peripheral surface formed into a circular-arc shape around an axis line;
- a tube having flexibility which is arranged along the inner peripheral surface;
- a pair of roller units which are housed in the housing unit, and are rotated around the axis line from a contact position to a separate position around the axis line in a state where the pair of roller units compress the tube;
- a pair of motors which are configured to rotate the pair of roller units respectively around the axis line in a same direction;
- and
- a control unit which is configured to control each of the pair of motors such that a liquid which flows into the tube from one end of the tube is discharged from the other end of the tube,
- wherein the control unit is configured to control each of the pair of motors such that, when one of the pair of roller units passes the separate position, an angular velocity of the other of the pair of roller units toward the separate position is gradually decreased.
A method for controlling a tube pump system which comprises:
- a housing unit which has an inner peripheral surface formed into a circular-arc shape around an axis line;
- a tube having flexibility which is arranged along the inner peripheral surface;
- a pair of roller units which are housed in the housing unit, and are rotated around the axis line from a contact position to a separate position around the axis line in a state where the pair of roller units compress the tube;
- and a pair of motors which are configured to rotate the pair of roller units respectively around the axis line in a same direction,
- the method comprising a controlling step of controlling each of the pair of motors such that a liquid which flows into the tube from one end of the tube is discharged from the other end of the tube,
- wherein, in the controlling step, each of the pair of motors is configured to be controlled such that, when one of the pair of roller units passes the separate position, an angular velocity of the other of the pair of roller units toward the separate position is gradually decreased.
