Polyester using cotton has been mainly used for bedding such as bed mattress material, but recently, it is harmless to the human body compared to the existing insulation and sound absorbing materials such as glass wool or rock wool, and it is characterized as an environmentally friendly material that can be recycled. It is greatly attracting attention as a substitute for these.

As a general method of producing a plush, the low melting point short fibers and the high melting point short fibers having different melting points shown in FIG. 1 are opened with a yarn-like yarn using the opening means 100, and the opened fibers are fixed.

Referring to the operation of the present invention having such a structure to adjust the thickness of the chamber housing 30 using the thickness adjusting means 10 as shown in the accompanying drawings first. In the method of adjusting the thickness of the chamber housing 30, the nut 16 is separated from the positioning rod member 19, and then the rotating shaft 17 to which the holder head 18 is fitted is rotated using a tool not shown in the drawing. As the rotating shaft 17 is rotated, the pinion 14 arranged on the rotating shaft 17 is rotated.

Since the pinion 14 is meshed with the rack gear 13, the pinion 14 moves along the rack gear 13. That is, as shown in FIG. 5, when the thickness of the chamber housing 30 is W, the pinion 14 is moved along the rack gear 13 by the pinion 14 by the rotation direction of the rotation shaft 17. When moved by W1 the thickness of the chamber housing 30 is adjusted to W2.

As shown in FIG. 6A, the flow plate 11 is manually adjusted using the rotating shaft 17, but as shown in FIG. 6B, the fluid plate 11 is controlled using the hydraulic cylinder 10-a. You can also adjust

When the thickness of the chamber housing 30 is adjusted, the yarn is opened by the yarn supply device not shown in the drawing, and the yarn is blown by air while being supplied by the air to the space 33 of the chamber housing 30. The yarns are stacked in the space 33.

As shown in FIG. 9, when the yarns are stacked in the chamber housing 30, the yarns are stacked on the top of the yarns by being biased only in a central portion or a partial region.

At this time, the air is blown from the plane holding device 40 made of the injection nozzle to blow up the stacked yarn so that the top of the stacked yarn becomes flat. The reason why the yarns piled up in a part by air using the plane holding device 40 is that the partially piled up part of the yarns during the manufacturing of the cushion material is compressed by its own weight, so as to form harder than other parts like the knots of wood. To do this.

The plane holding device 40 is installed on the side of the chamber housing 30 at regular intervals to operate the plane holding device 40 according to the stacking height.

Meanwhile, when the yarns are stacked, the yarn alignment device 20 simultaneously operates to align the stacked yarns. The aligning method of the yarns is an eccentric shaft 23 by the driving force of the driving motor 22 as shown in the accompanying drawings. When rotated, the yarn alignment plate 21 to which the eccentric shaft 23 is connected oscillates left and right, and the top of the yarn alignment plate 21 on one side of the chamber housing 30 is rotated about the hinge shaft 26 to be stacked. Lined yarn is aligned.

Therefore, the thickness and density is controlled, and furthermore, the pipe fitting hole 11-1 of the suction pipe connected to the air suction device not shown in the drawing connected to the thickness and density control device of the present invention is an air suction part 11-3. ) And then sucked air discharges the air introduced into the inner space 33 of the chamber housing 30 through the filter member 11-2 of the mesh shape.

Therefore, only the air supplied while the stacked yarns are fed together with the air is discharged by the air absorber shown. When the air introduced into the chamber housing 30 is discharged, noise is generated by the vacuum, and the generation of the noise is caused by the external air being sucked through the air suction through-hole 21a provided at the bottom of the yarn alignment 21. Because it is prevented.

When the stack is laminated as described above and the thickness and density of the laminate is controlled and discharged at a constant rate by using a stack discharge means (not shown in the drawing) installed in the chamber housing 30 attached to the drawings Figure 11 As shown in the random tissue is excellent in elasticity and resilience, there is an effect that can produce a cushioning material excellent in sound absorption and moisture permeability.
