Abstract
A feeding device for a flowable material is provided with a platen housed in a container containing the flowable material, a cylindrical ram attached to the platen, a pump that reciprocates a piston housed in the ram to suck up the flowable material in the container and a determination device configured to determine a replacement time of the container based on a change in a moving speed of the piston.
Claims4
A feeding device for a flowable material, comprising:
- a platen housed in a container containing the flowable material;
- a cylindrical ram attached to the platen;
- a pump that reciprocates a piston housed in the ram to suck up the flowable material in the container;
- and
- a determination device configured to determine a replacement time of the container based on a change in a moving speed of the piston, wherein
- when an amount of change in the moving speed of the piston becomes equal to or greater than a predetermined amount, the determination device is configured to determine that a time for replacing the container has arrived.

- a platen housed in a container containing the flowable material;
- a cylindrical ram attached to the platen;
- a pump that reciprocates a piston housed in the ram to suck up the flowable material in the container;
- and
- a determination device configured to determine a replacement time of the container based on a change in a moving speed of the piston, wherein
- the determination device comprises:
- a vibration sensor mounted at an arbitrary position to which vibration generated by reciprocation of the piston is transmitted;
- and
- an electronic control unit configured to calculate a period of vibration generated when the piston moves to a top dead center and a bottom dead center based on a detection value of the vibration sensor, and to detect a change in the moving speed of the piston based on the period.
