Abstract
A raw material supply device includes a plurality of supply portions for supplying the raw material, a detection portion for detecting a state of the supply portion, and a control portion for controlling the supply portion, in which when the plurality of supply portions are in a normal state, the control portion switches the supply portions at a predetermined timing, and causes each of the supply portions to supply the raw material.
Claims8
A raw material supply device comprising:
- a plurality of supply portions that supply a raw material;
- a detection portion that detects a state of the supply portions;
- and
- a control portion that controls the supply portions,
- wherein when the plurality of supply portions are in an operation state, the control portion switches the supply portions at a predetermined timing, and causes each of the supply portions to supply the raw material,
- upon the control portion determining that one supply portion of the supply portions is abnormal, the control portion causes the one supply portion to be in a pause state and causes a different supply portion of the supply portions to be in the operation state to supply the raw material, and
- upon the control portion determining that abnormality of the one supply portion is eliminated, the control portion causes the one supply portion to shift from the pause state to a standby state in which the one supply portion waits without supplying the raw material, and causes the one supply portion to shift from the standby state to the operation state so as to switch the supply portions including the one and different supply portions and cause each of the supply portions to supply the raw material.
A raw material supply method of a raw material supply device including a plurality of supply portions for supplying a raw material, the method comprising:
- switching the supply portions at a predetermined timing, and causing each of the supply portions to supply the raw material when the plurality of supply portions are in an operation state;
- upon determining that one supply portion of the supply portions is abnormal, causing the one supply portion to be in a pause state and causing a different supply portion of the supply portions to be in the operation state to supply the raw material;
- and
- upon determining that abnormality of the one supply portion is eliminated, causing the one supply portion to shift from the pause state to a standby state in which the one supply portion waits without supplying the raw material, and causing the one supply portion to shift from the standby state to the operation state so as to switch the supply portions including the one and different supply portions and cause each of the supply portions to supply the raw material.
