Abstract
Provided is a tube pump system including: a tube pump; a pipe including a flow channel causing a liquid delivered from a tube to flow formed therein; an orifice arranged at a first predetermined position; a selector valve arranged at a second predetermined position; and a control unit. The control unit controls the tube pump and the selector valve to synchronize a delivering timing to switch the tube pump from the stop state to the delivering state and a flowing timing to switch the selector valve from the blocking state to the flowing state and synchronize a stop timing to switch the tube pump from the delivering state to the stop state and a blocking timing to switch the selector valve from the flowing state to the blocking state.
Claims7
A tube pump system comprising:
- a tube pump configured to deliver a liquid in a tube formed of a flexible material by intermittently pinching the tube and perform switching between a delivering state for delivering a liquid and a stop state for not delivering a liquid;
- a pipe connected to the tube at one end of the pipe and including a flow channel formed inside the pipe, the flow channel causing a liquid delivered from the tube to flow in a flow direction from the one end to the other end;
- a reduced diameter part arranged at a first predetermined position between the one end and the other end of the pipe and providing the smallest sectional area of a channel cross section orthogonal to the flow direction in the flow channel;
- a selector valve arranged at a second predetermined position between the one end and the other end of the pipe and configured to perform switching between a flowing state where a liquid passes through the second predetermined position and a blocking state where a liquid flow is blocked at the second predetermined position;
- and
- a control unit configured to control the tube pump and the selector valve so that a liquid is intermittently ejected from the other end of the pipe,
- wherein the first predetermined position is located between the one end of the pipe and the second predetermined position,
- wherein the control unit controls the tube pump and the selector valve to synchronize a delivering timing and a flowing timing and synchronize a stop timing and a blocking timing, the delivering timing being a timing to switch the state of the tube pump from the stop state to the delivering state, the flowing timing being a timing to switch the state of the selector valve from the blocking state to the flowing state, the stop timing being a timing to switch the state of the tube pump from the delivering state to the stop state, and the blocking timing being a timing to switch the state of the selector valve from the flowing state to the blocking state.

A control method of a tube pump system, wherein the tube pump system comprises
- a tube pump configured to deliver a liquid in a tube formed of a flexible material by intermittently pinching the tube and perform switching between a delivering state for ejecting a liquid and a stop state for not delivering a liquid,
- a pipe connected to the tube at one end of the pipe and including a flow channel formed inside the pipe, the flow channel causing a liquid delivered from the tube to flow in a flow direction from the one end to the other end,
- a reduced diameter part arranged at a first predetermined position between the one end and the other end of the pipe and providing the smallest sectional area of a channel cross section orthogonal to the flow direction in the flow channel, and
- a selector valve arranged at a second predetermined position between the one end and the other end of the pipe and configured to perform switching between a flowing state where a liquid passes through the second predetermined position and a blocking state where a liquid flow is blocked at the second predetermined position,
- wherein the first predetermined position is located between the one end of the pipe and the second predetermined position,
- the control method comprising:
- a first control step of controlling the tube pump and the selector valve to synchronize a delivering timing and a flowing timing, the delivering timing being a timing to switch the state of the tube pump from the stop state to the delivering state, and the flowing timing being a timing to switch the state of the selector valve from the blocking state to the flowing state;
- and
- a second control step of controlling the tube pump and the selector valve to synchronize a stop timing and a blocking timing, the stop timing being a timing to switch the state of the tube pump from the delivering state to the stop state, and the blocking timing being a timing to switch the state of the selector valve from the flowing state to the blocking state.
