Abstract
Official abstract text for this publication.
A sheet manufacturing apparatus is an apparatus that heats a material containing fibers to form a sheet, and includes a heating portion that heats the material, and a control portion that controls a temperature at which the heating portion heats the material. The control portion sets a temperature of the heating portion to a first temperature in a first state where the sheet manufacturing apparatus manufactures the sheet, and sets the temperature of the heating portion to a second temperature lower than the first temperature at a predetermined timing in a second state where the sheet is not manufactured, or at a predetermined timing when a state of the sheet manufacturing apparatus is shifted to the state where the sheet is not manufactured.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sheet manufacturing apparatus heating a material containing fibers to form a sheet, the apparatus comprising: a heating portion that heats the material; and a control portion that controls a temperature at which the heating portion heats the material, wherein the control portion sets a temperature of the heating portion to a first temperature in a state where the sheet manufacturing apparatus manufactures the sheet, the control portion sets the temperature of the heating portion to a second temperature lower than the first temperature at a predetermined timing in a state where the sheet is not manufactured and the control portion controls the heating portion to be ON, or at a predetermined timing when a state of the sheet manufacturing apparatus is shifted from the state where the sheet manufacturing apparatus manufactures the sheet to the state where the sheet is not manufactured and the control portion controls the heating portion to be ON, and the control portion starts counting a standby time in response to the state of the sheet manufacturing apparatus being shifted to the state where the sheet is not manufactured and the control portion controls the heating portion to be ON, and the control portion changes the temperature of the heating portion from the second temperature to a third temperature lower than the second temperature when a time period in which the control portion counts the standby time reaches a predetermined set time period. 2. The sheet manufacturing apparatus according to claim 1 , further comprising a reception portion that receives an input from an outside, wherein the control portion changes the temperature of the heating portion from the first temperature to the second temperature, or from the second temperature to the first temperature in response to the input received by the reception portion. 3. The sheet manufacturing apparatus according to claim 2 , wherein the reception portion is configured to receive an input of a type of the sheet to be manufactured, and the control portion changes the temperature of the heating portion from the first temperature to the second temperature, or from the second temperature to the first temperature according to a change in the type of the sheet to be manufactured, by the input in the reception portion. 4. The sheet manufacturing apparatus according to claim 1 , further comprising: a supply portion that supplies a plurality of types of raw materials, each containing fibers; and a defibrating portion that defibrates the raw material supplied by the supply portion, wherein the control portion changes the temperature of the heating portion from the first temperature to the second temperature, or from the second temperature to the first temperature according to a change in a type of the raw material supplied by the supply portion. 5. The sheet manufacturing apparatus according to claim 4 , further comprising a plurality of accommodation portions that accommodate the plurality of types of the raw materials for the respective types, wherein the supply portion selects and supplies any one of the plurality of types of the raw materials accommodated in the accommodation portion. 6. The sheet manufacturing apparatus according to claim 1 , further comprising a cartridge that contains a binding material, wherein the control portion acquires temperature information from the cartridge, and determines the first temperature based on the acquired temperature information. 7. The sheet manufacturing apparatus according to claim 1 , further comprising a cartridge that contains a binding material, wherein the control portion acquires temperature information from the cartridge, and determines the second temperature based on the acquired temperature information. 8. The sheet manufacturing apparatus according to claim 1 , further comprising a transport portion that transports the material to the heating portion, wherein at least an operation of transporting the material to the heating portion by the transport portion is performed in the state where the sheet is manufactured, and at least the transport portion is stopped in the state where the sheet is not manufactured and the control portion controls the heating portion to be ON. 9. The sheet manufacturing apparatus according to claim 1 , further comprising a humidifying portion that has a heat source and humidifies the material, wherein the heat source of the humidifying portion is operated in the state where the sheet is not manufactured and the control portion controls the heating portion to be ON. 10. The sheet manufacturing apparatus according to claim 1 , wherein the control portion changes the temperature of the heating portion from the first temperature to the second temperature based on a time during which the state where the sheet is not manufactured and the control portion controls the heating portion to be ON continues. 11. The sheet manufacturing apparatus according to claim 1 , wherein the control portion stops a control of the temperature of the heating portion based on a time during which the state where the sheet is not manufactured and the control portion controls the heating portion to be ON continues. 12. The sheet manufacturing apparatus according to claim 1 , wherein the sheet is configured to be manufactured based on a job including at least an instruction to start and end manufacture of the sheet, or designation of a manufacturing volume, and the control portion shifts the state of the sheet manufacturing apparatus to a suspended state where the sheet is not manufactured and the control portion controls the heating portion to be ON during an operation of manufacturing the sheet based on the job, and sets the temperature of the heating portion to the second temperature lower than the first temperature in the suspended state. 13. The sheet manufacturing apparatus according to claim 1 , wherein the sheet is configured to be manufactured based on a job including at least an instruction to start and end manufacture of the sheet, or designation of a manufacturing volume, and the control portion shifts the state of the sheet manufacturing apparatus to a standby state where the sheet is not manufactured and the control portion controls the heating portion to be ON after an operation of manufacturing the sheet based on the job is completed, and changes the temperature of the heating portion from the first temperature to the second temperature based on a time during which the standby state continues. 14. The sheet manufacturing apparatus according to claim 1 , wherein the control portion changes the temperature of the heating portion from the second temperature to the first temperature in response to the input from an outside. 15. The sheet manufacturing apparatus according to claim 1 , wherein the heating portion includes a heating roller pair that interposes and heats the material, the heating roller pair is configured to be displaced between a first position interposing the material and a second position not interposing the material, and the control portion displaces the heating roller pair to the second position, when the control portion changes the temperature of the heating portion from the first temperature to the second temperature. 16. A control method of a sheet manufacturing apparatus heating a material containing fibers to form a sheet, the sheet manufacturing apparatus including a heating portion that heats the material, and a control portion that controls a temperature at which the heating portion
