Abstract

Official abstract text for this publication.

A sheet manufacturing apparatus configured to manufacture a sheet by heating and pressurizing a material containing a fiber and an additive agent includes a supplying unit configured to supply the additive agent in air, a first tank configured to communicate with the supplying unit and store the additive agent, and a second tank configured to communicate with the first tank, store the additive agent, and be able to detach from the sheet manufacturing apparatus.

First claim

Opening claim text (preview).

What is claimed is: 1. A sheet manufacturing apparatus configured to manufacture a sheet by heating and pressurizing a material containing a fiber and an additive agent, the apparatus comprising: a supplying opening configured to supply an additive agent in air; a first tank configured to communicate with the supplying opening and store the additive agent, the first tank including a first photoelectric detector configured to detect an absence of the additive agent in the first tank, a second photoelectric detector configured to detect that an amount of the additive agent in the first tank reaches an upper limit, and a third photoelectric detector disposed between the first photoelectric detector and the second photoelectric detector in a vertical direction and configured to detect the amount of the additive agent in the first tank and; and a second tank configured to communicate with the first tank and store the additive agent, the second tank being detachably attached to the sheet manufacturing apparatus, the second tank including a screw feeder configured to transport the additive agent from the second tank to the first tank, the screw feeder being configured to commence to transport the additive agent from the second tank to the first tank in response to the third photoelectric detector detecting the amount of the additive agent in the first tank, the second tank including an opening through which the second tank is configured to communicate with the first tank and including a valve slidable relative to the opening of the second tank between an opening position at which the valve opens the opening of the second tank and a closing position at which the valve closes the opening of the second tank. 2. The sheet manufacturing apparatus according to claim 1 , wherein the first tank includes a hole configured to communicate with an outside of the first tank on the upper side thereof. 3. The sheet manufacturing apparatus according to claim 1 , wherein the second tank further includes a fourth photoelectric detector configured to detect an absence of the additive agent in the second tank.
