Description

  The present invention relates to a fiber assembly cutting device, a cutting method, and a vacuum heat insulating material.

In recent years, energy saving is desired because of the importance of preventing global warming, which is a global environmental problem. A heat insulating material using a fiber aggregate (for example, an inorganic fiber aggregate such as glass fiber or rock wool) is widely used in residential, architectural, industrial and consumer applications because of its excellent thermal insulation performance. Fiber aggregates such as glass fiber and rock wool have a specific problem that fiber powder as a broken piece touches the human body, and this countermeasure is necessary.
Further, it is necessary to wrap the outside of the fiber assembly with an outer packaging material in order to prevent irritation to the specific skin and to prevent deterioration due to moisture absorption.

  For example, in Patent Document 1, in the production of an inorganic fiber mat for heat insulation, the upper surface and the lower surface of the heat insulating material are respectively coated with a synthetic resin film serving as an outer packaging material, and then the upper surface and the lower surface film are bonded to each other. The entire surface is covered with a film to prevent irritation and discomfort caused by fibers scattering and tingling from the end face of the mat. Moreover, in patent document 2, glass fiber is pressure-molded at a predetermined temperature, the fiber is stretched by thermal deformation of the glass fiber, and a part of the glass fiber is entangled between the fibers rather than being bound to each other. By maintaining the shape, powder falling during handling is reduced. Further, in Patent Document 3, as a fiber assembly cutting device in a heat insulating material manufacturing process, a vertically moving saw blade is advanced in the thickness direction of the fiber assembly, and when the saw blade rises, There is described a device for preventing glass fiber powder from being scattered by being lifted on a blade edge, bent, broken and cut.

In FIG. 1, the mounting table 5 is divided into two parts in the front-rear direction with respect to the direction in which the fiber assembly 7 is conveyed at the insertion site of the blade 2, and includes a front mounting table 5a and a rear mounting table 5b. The blade 2 enters the gap generated by this division. The front mounting table 5 a has a function of a feed conveyor that conveys the fiber assembly 7 toward the blade 2. Further, the rear mounting table 5b has a function of a conveyor that conveys the cut fiber assembly backward. A payout conveyor 6 is disposed further rearward of the rear mounting table 5b.

  The compression mechanism 3 is divided into two in the front and rear directions in the same manner as the mounting table 5, and is composed of a front compression mechanism 3 a and a rear compression mechanism 3 b, and a gap generated by dividing the mounting table on the upper surface of the mounting table 5. It is extended and arranged on both sides across The front compression mechanism 3a and the rear compression mechanism 3b are engaged with linear actuators such as an air cylinder and a hydraulic cylinder (not shown), for example, so that the fiber assembly 7 can be driven in the compression direction.
