[0007]

In the heating of the raw material fibers, it is preferable to supply high-temperature heated air at a high speed in order to improve efficiency. However, the Young's modulus of the raw fiber decreases with increasing temperature, and the bulkiness may decrease. Therefore, the raw fibers are compressed by the wind pressure received with the rise in temperature, and the flow air resistance on the surface increases and the flow air amount may further decrease. In such a mixture of raw fibers, it is necessary to reduce the flowing air velocity and to process the raw fibers at a small flow rate in order to maintain a predetermined bulkiness of the raw fibers. However, this requires considerable time and is inefficient. In view of the above, an object of the present invention is to maintain the density of raw fiber at a predetermined value and efficiently heat-treat the filling.

According to a third aspect of the present invention, a raw material fiber containing a fiber exhibiting adhesiveness at least by heating and melting is spread or mixed, continuously sent out, compressed to a predetermined thickness, and heat-molded. In the method of forming a filling, the flow path of the raw fiber is divided into a plurality of sections, and the heated air is circulated in each section, and the flowing air velocity is sequentially reduced in each of the divided sections as the temperature of the raw fiber increases. Then, when the raw material fibers are cooled, the gist is that the flow speed of the cooling air is sequentially increased in each of the divided sections in accordance with the temperature decrease of the raw material fibers.

[0015]

FIG. 1 shows an example in which the present invention is applied to a heat treatment molding apparatus for a filling material, for example, a compression molding member of a filling material, for example, a cushion material, which is obtained by compression molding raw material fibers into a mold. 1 includes a heating chamber 2 for accommodating the same formwork W for compressing and accommodating the raw fibers, and a circulation duct 3 for supplying heated air to the heating chamber 2. Heating chamber 2 is mold W
A support duct 4 is placed above the support stand, and an exhaust duct 5 is connected above the support base. The duct 5 is connected to a circulation fan 6, and a discharge duct of the fan 6 opens at a lower portion of the heating chamber 2. The circulation duct 3 houses an air heater 7.

In the drawing, reference numeral 8 denotes an opening of the heating chamber 2 for receiving the mold W, which is also formed on the opposite side, and each of which is provided with an opening / closing door, but is not shown. The supply of the raw material fibers into the mold W is performed by a known means, for example, the compression molding mechanism 52 shown in FIG.
The description is omitted.

The form support 4 of the heating chamber 2 forms an air circulation port 9 at a portion where the form W is placed, and a perforated passage 10 is formed at an appropriate place other than the form placing portion. An adjustment damper 11 is provided on this. Note that the adjustment damper 11 may be provided above the circulation duct 3 and serve as an exhaust port without providing the bypass passage 10.

In the above configuration, the supplied form W is placed on the flow port 9 of the support base 4, and the circulation fan 6 is driven to circulate the heated air to heat the form W. However, when the temperature of the raw material fibers in the first mold decreases, the adjustment damper 11 is closed, and the entire amount of circulating air is passed through the mold W. Then, as the temperature of the raw material fibers in the mold increases, the adjustment dampers 11 are sequentially opened, and the amount of air supplied to the mold W is reduced. FIG. 2 shows an example of the procedure.

FIG. 1 shows the relationship between time, temperature and air flow. A shows the curve of time-temperature of supply air. In C), it rises in a substantially linear shape. The amount of circulating air at this time is indicated by V1, and the amount of air passing through the inside of the mold W is indicated by B. Along with this, the temperature of the raw fibers in the mold W also rises due to a slight delay. C shows the time-temperature curve of the fiber. In this case, when the temperature reaches a temperature slightly before reaching the softening temperature T3 of the low melting point fiber contained in the raw material fiber, the damper 11 is gradually opened, and a part of the heated air is discharged from the bypass passage 10 and the raw material is discharged. As the temperature of the fiber increases, its release increases. D in the figure indicates a time-discharge amount curve of the discharge air from the bypass passage.

That is, the supply amount of the heated air into the mold is increased when the raw material fiber is at a low temperature, and starts decreasing as the temperature approaches the softening temperature. To be large. That is, when the raw material fiber has a low Young's modulus at a low temperature, the amount (speed) of the heated air is increased, and the supply air speed decreases as the temperature increases and the Young's modulus decreases. As a result, the raw fiber is compressed by the flow resistance of air,
There is no risk that the density will change.

FIG. 3 shows a second embodiment. The figure shows a first example in which the present invention is applied to a method for forming a continuous filling. The heat treatment molding apparatus 20 for the filling includes a heating mechanism 21 for receiving and heating the raw material fibers forming the layers fed from a plurality of, for example, three raw fiber supply mechanisms E1, E2, E3 (hereinafter, simply referred to as E). , And a cooling mechanism 22 provided at the rear side. The stuffing in this embodiment has a continuous shape and can be used not only as a stuffing but also as a nonwoven fabric for a filter or the like.

The heating mechanism 21 includes a common lower conveyor belt 23 for stacking and placing the layered material fibers S fed from the material fiber supply mechanism E, an upper conveyor belt 24 opposed thereto, and an upper conveyor belt 24. Heated air supply chamber 25 provided on belt 24 and lower conveyor belt 2
A plurality (four in the example in the figure) of hoppers 26 arranged below
a, 26b (hereinafter collectively referred to simply as 26) and a heating air circulating circuit 27 for applying suction to each hopper 26 and supplying heating air to the heating air supply chamber 25. Each of the hoppers 26 is provided with an adjustment damper 28a, 28b...
8) is connected to the suction side of the circulation fan 29 of the heating air circulation circuit 27. The discharge side of the circulation fan 29 is connected to the heated air chamber 25 via the heater 30. In the drawings, 31a, 31b, 31c... Are guide rollers attached to the tip of each hopper, which support the lower conveyor belt 23 and partition each hopper.

The raw material fiber supply mechanism E has a well-known structure, and the figure shows an example thereof. At least two or more types of raw material fibers are mixed by an appropriate cotton mixing machine (not shown), and the hopper is mixed by air flow. It is transported to Ea, which is opened by an opening beater Eb, and sent out by a feeding roller Ec. In the figure, three raw fiber supply mechanisms E are provided to form a filling having a required thickness.

The cooling mechanism 22 is connected to the upper conveyor belt 2.
4 and a plurality (three in the figure) of hoppers 33a, 33b, 33c provided below the lower conveyor belt 23 (hereinafter referred to simply as 33). ), And each hopper 33 is connected to the exhaust fan 35 via adjustment dampers 34a, 34b, 34c (hereinafter, simply referred to as 34).

The adjusting damper 28 for each hopper 26 of the heating mechanism 21 increases the opening degree of the material fiber supply side, that is, 28a, and sequentially narrows the opening toward the rear damper, thereby decreasing the opening degree. That is, the flow speed of the heated air is increased on the hopper 26a side, and is gradually reduced toward the rear. In the cooling mechanism 22, the adjusting dampers 34 for the respective hoppers 33 are configured such that the opening degree of the damper 34a on the upstream side is small, and the opening degree is gradually increased toward the downstream side. As a result, the suction speed of the outside air is low on the hopper 33a side, and the suction speed gradually increases toward the rear.

In this state, the continuous belt-shaped raw fiber S sent from the raw fiber supply mechanism E is heated by the heating mechanism 2.
When the temperature reaches 1, the room temperature is still normal and the Young's modulus is large. Therefore, even if the flowing air velocity is high at the position facing the hopper 26a, the raw fibers do not bend strongly, and the heating efficiency can be improved by increasing the air velocity. And as the raw material fiber S moves, its temperature rises and Young's modulus decreases,
The circulating air velocity gradually decreases, so that the raw fibers are not compressed by the wind pressure, reach a predetermined temperature, the low melting fibers are melted and adhered to each other and between the molten fibers and the non-molten fibers, and A padding is formed that retains the desired density and cushioning properties.

Next, the raw material fibers are transferred to the cooling mechanism 22. At this time, the raw material fiber is at a high temperature, but at first, it is not affected by the wind pressure by reducing the suction speed of the outside air, and the cooling is performed by sequentially increasing the suction wind speed as the temperature decreases. It can be done effectively.

FIG. 4 shows a third embodiment. In this embodiment, a plurality of hoppers are provided in opposition to the raw material fiber layer to be shifted in the second embodiment, and the suction wind speed of each hopper is sequentially changed. Reference numeral 44 denotes a hopper provided for the punching metal 43. The other parts are the same as those in the previous example, and the same parts are denoted by the same reference numerals and description thereof will be omitted. Reference numerals 45 are guide rollers provided at both ends of the hopper, which support the lower conveyor belt 23 and maintain airtightness between the hopper and the conveyor belt.

The perforation 4 of the punching metal 43
3a, on the receiving side of the raw fiber, the pore diameter is increased or the gap between the pores is reduced to increase the air flow rate per unit area (circulation speed), and the pore diameter is gradually reduced or reduced toward the rear. The gap between them is set to be large, and the amount of circulating air per unit area (circulating speed) is set to be small.

Similarly, in the cooling mechanism 42, a plurality of hoppers are provided in opposition to the moving raw material fiber layer in the cooling mechanism 22 in the second embodiment, and the suction wind speed of each hopper is sequentially changed. The punching metal 46 performs this. Reference numeral 47 denotes a hopper provided for the punching metal 46. The other parts are the same as those in the previous example, and the same parts are denoted by the same reference numerals and description thereof will be omitted. Reference numerals 48 are guide rollers provided at both ends of the hopper, which support the lower conveyor belt 23 and maintain the airtightness between the hopper and the conveyor belt.

The perforation 4 of the punching metal 46
6a, on the upstream side, the hole diameter is small or the distance between the holes is large, the air flow rate (speed) per unit area is small, and the hole diameter is large or the distance between the holes is small gradually toward the rear. , Air flow rate per unit area (flow rate)
Is set to be large.

In the above configuration, the continuous band-shaped raw material fiber S fed from the raw material fiber supply mechanism E has a large amount of air at first due to the punching metal 43 in the heating mechanism 41, but the temperature rises as it proceeds. And the flowing air velocity decreases. Accordingly, as in the previous example, the raw fibers are not compressed by the wind pressure, thereby forming a filling having a predetermined density.

In the cooling mechanism 42, the suction speed is initially reduced by the punching metal 46 as in the previous example, so that the suction speed is not affected by the wind pressure. Can be performed effectively.

[0034]

As described above, according to the present invention, when flowing heated air through the raw fibers for heating and forming the raw fibers filled to a predetermined thickness, the flow rate of the heated air is controlled by the temperature of the raw fibers. Since the Young's modulus is gradually decreased in accordance with the decrease in Young's modulus, a padding having a predetermined density can be formed. Further, at the time of cooling, the heat treatment can be efficiently performed by sequentially increasing the flow rate of the cooling air as the temperature of the raw fiber decreases. Further, when the heated air is circulated from below, the deformation due to the own weight of the molded article itself can be reduced by the wind pressure, and it is not necessary to greatly reduce the supply of the air volume as compared with the case where the heated air is circulated from above. , The production efficiency can be improved.
