Document Type and Number:
Japanese Patent JP2022092768
Kind Code:
A
Abstract:
To provide an excellent extrusion molding device.SOLUTION: There is provided an extrusion molding device that comprises: an extruder; a pump; a pressure sensor; and a control unit, in which in order to control a measured pressure measured by the pressure sensor into a target pressure, the control unit that feedback-controls a rotation speed of the pump is configured to: determine a current state and a reward for a previously selected action based on a difference between the measured pressure and the target pressure; update a control condition that is a combination of the state and the action based on the reward, and select an optimum action corresponding to the current state from the updated control condition; and control the rotation speed of the pump based on the optimal action.SELECTED DRAWING: Figure 4
