Abstract

A sheet manufacturing apparatus that manufactures a sheet-shaped recycled paper using coarsely crushed pieces obtained by coarsely crushing a sheet containing fibers as a raw material, includes a container loading section that is configured to load a container in which the coarsely crushed pieces are housed and which has an information carrying section for carrying information related to characteristics of the housed coarsely crushed pieces, a reading section that reads the information carried by the information carrying section, a determination section that determines whether or not the coarsely crushed pieces in the container are suitable as the raw material for sheet manufacturing by the sheet manufacturing apparatus based on the information read by the reading section, and a switching section that switches between a first state in which the container is configured to be loaded into the container loading section and a second state in which the container is prevented from being loaded into the container loading section according to a determination result of the determination section.

Claims (23)

1. A sheet manufacturing apparatus that manufactures a sheet-shaped recycled paper using coarsely crushed pieces obtained by coarsely crushing a sheet containing fibers as a raw material, the sheet manufacturing apparatus comprising:

a container loading section that is configured to load a container in which the coarsely crushed pieces are housed and which has an information carrying section for carrying information related to characteristics of the housed coarsely crushed pieces;

a reading section that reads the information carried by the information carrying section;

a determination section that determines whether or not the coarsely crushed pieces in the container are suitable as the raw material for sheet manufacturing by the sheet manufacturing apparatus based on the information read by the reading section; and

a switching section that switches between a first state in which the container is configured to be loaded into the container loading section and a second state in which the container is prevented from being loaded into the container loading section according to a determination result of the determination section.

2. The sheet manufacturing apparatus according to claim 1 , further comprising:

an insertion port that loads the container into the container loading section; and

an opening/closing door that is provided at the insertion port to open and close the insertion port, wherein

the switching section has an opening/closing drive section that switches between the first state in which the opening/closing door is in an opened state and the second state in which the opening/closing door is in a closed state.

3. The sheet manufacturing apparatus according to claim 1 , further comprising:

an insertion port that loads the container into the container loading section; and

an opening/closing door that is provided at the insertion port to open and close the insertion port, wherein

the switching section has a locking section that switches between the first state in which the opening/closing door is in a locking released state and the second state in which the opening/closing door in a closed state is in a locked state.

4. The sheet manufacturing apparatus according to claim 1 , wherein

the information carried by the information carrying section is at least one piece of information of a shape, a size, a thickness, a basis weight, a paper type, a paper quality, a whiteness, a bulk density of a fiber, an average fiber length, and a water content of the coarsely crushed pieces.

5. The sheet manufacturing apparatus according to claim 1 , wherein

the information carried by the information carrying section includes at least one of ID information of a user who is permitted to use the sheet manufacturing apparatus and ID information of the sheet manufacturing apparatus, as additional information.

6. The sheet manufacturing apparatus according to claim 1 , wherein

the information carrying section is a two-dimensional or three-dimensional code, and

the reading section is a code reader.

7. The sheet manufacturing apparatus according to claim 1 , wherein

the information carrying section is an IC tag, and

the reading section is an IC reader.
