Abstract

A sheet fabrication apparatus includes: a fiber separation unit that micronizes an ingredient; a first sensor unit that measures a temperature in a first space including the fiber separation unit; a first air conditioning unit that adjusts the temperature in the first space; a fabrication unit that works the fiber separated articles obtained by micronizing the ingredient by the fiber separation unit; a second sensor unit that measures at least either a temperature or a humidity at a mounting position of the fabrication unit; and a control unit that controls the first air conditioning unit on the basis of at least any of measurement results of the first sensor unit and the second sensor unit.

First claim

What is claimed is:

1. A fiber ingredient reproduction apparatus comprising:
a micronizing unit configured to micronize an ingredient;
a first measurement unit configured to measure a temperature in a first chamber housing the micronizing unit;
a first air conditioner configured to adjust the temperature in the first chamber;
a classification unit that classifies the micronized ingredients, the classification unit being positioned outside the first chamber;
a second measurement unit configured to measure a temperature, a humidity, or both a temperature and a humidity at a mounted position of the classification unit; and
a control unit configured to control the first air conditioner based on a measurement result of the first measurement unit, the second measurement unit, or both the first measurement unit and the second measurement unit.

2. The fiber ingredient reproduction apparatus according to claim 1 ,
wherein the control unit is configured to operate the first air conditioner based on the measurement result of the second measurement unit.

3. The fiber ingredient reproduction apparatus according to claim 2 ,
wherein the second measurement unit is configured to measure a temperature and a humidity at the mounted position of the classification unit, and
wherein the control unit is configured to set a target temperature in the first chamber based on the temperature and the humidity measured by the second measurement unit and the control unit is configured to operate the first air conditioner in accordance with the set target temperature.

4. The fiber ingredient reproduction apparatus according to claim 3 ,
wherein the control unit is configured to obtain a dew point temperature at the mounted position of the blade based on the measurement result of the second measurement unit and the control unit is configured to set the target temperature in the first chamber to a temperature that is equal to or less than the dew point temperature.

5. The fiber ingredient reproduction apparatus according to claim 1 , further comprising:
a second air conditioner configured to adjust a temperature and a humidity in a second chamber in which the classification unit is mounted,
wherein the second measurement unit is configured to measure a temperature, a humidity, or a temperature and a humidity in the second chamber, and
wherein the control unit is configured to control the second air conditioner based on target values set in advance for the temperature and the humidity in the second chamber and the measurement result of the second measurement unit.

6. The fiber ingredient reproduction apparatus according to claim 1 ,
wherein the micronizing unit includes a shredding device, a fiber separation machine, or a shredding device and a fiber separation machine, the shredding device being configured to shred the ingredient in a sheet form, and the fiber separation machine being configured to perform fiber separation on the ingredient to obtain the ingredient in a fiber form.

7. The fiber ingredient reproduction apparatus according to claim 1 , further comprising:
a housing defining the first chamber and accommodating the micronizing unit,
wherein the first measurement unit is configured to measure the temperature in the first chamber that is an inner space of the first housing.

8. The fiber ingredient reproduction apparatus according to claim 1 , further comprising:
a second housing defining a second chamber and accommodating the classification unit,
wherein the second measurement unit is configured to measure a temperature, a humidity, or a temperature and a humidity in an inner space of the second housing.
