Title:
FIBER SPRAYING DEVICE
Document Type and Number:
Japanese Patent JP2022157869
Kind Code:
A
Abstract:
To provide a technique by which in a fiber spraying device used for spraying method of fiber composition by dry construction method or semi-dry construction method, pulsation is less likely to occur in a fiber pumping path, and it is less likely to occur that even when stopping supply of fibers such as rock wools and the like into the fiber pumping path, fine particles of the fibers staying in the fiber pumping path continue to eject from a fiber discharge port, and the fibers are clogged in the fiber pumping path.SOLUTION: A pressure in a fiber pumping path is measured by a pressure gauge fiber, pressure data Pm in the fiber pumping path at that time is transmitted to (K) calculator, and is compared to allowable pressure upper limit value data Pmax stored in a memory for an allowable pressure upper limit value and allowable pressure lower limit value data Pmin stored in a memory for an allowable pressure lower limit value. When the pressure data is out of an allowable pressure range, supply of fibers from a quantitative feeding device for a disengaging machine to a fiber pumping pipe is restrained or increased by a restraining order or increasing order from a controller.SELECTED DRAWING: Figure 1
