Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a product having a predetermined thickness and hardness obtained by heat-treating a fiber product made of heat-sealing fiber, resin cotton or the like (for industrial use, wheels, civil engineering, mats / beds). The present invention relates to a heat treatment molding machine (hereinafter referred to as a molding machine) capable of obtaining a basic fiber material for bedding and the like.

2. Description of the Related Art Conventionally, this kind of fiber product has been heat treated,
As a molding machine for obtaining the product, a molding machine usually called a slat conveyor is commercially available. In this molding machine, as shown in FIG. 8, slat conveyors having a large number of endless endways are arranged on the upper and lower sides, and a hot air supply device is arranged above the upper slat conveyors, and the lower side is also provided. The exhaust air suction device is provided below the slat conveyor, and the straightening roll group is provided at the end of the upper and lower slat conveyors. In order to obtain the product with a molding machine adopting this configuration, first, the fiber product is inserted between the upper and lower slat conveyors. This textile product is transported as the upper and lower slat conveyors advance, and is sequentially heat-treated with hot air supplied from above the upper slat conveyor. The heat-treated fiber product is then processed into a product having a predetermined thickness and hardness by pressing and molding the upper and lower straightening rolls, and then sent out as a product from the upper and lower slat conveyors. Be done.

As another molding machine, upper and lower net type endless belts made of wire nets are provided, a hot air supply device is provided above the upper net type endless belts, and the lower net type endless belts are provided. Of the net type endless belt, and a straightening roll group is provided at the end of the net type endless belt. Also in this molding machine, processing is performed in substantially the same manner as the above-mentioned example.

As a result of researching patent publications and the like for several years under the international classification, D (06) C, no relevant document was found.

[0005]

In the molding machine equipped with the slat conveyor, a gap is formed between the lateral walls of the upper and lower slat conveyors, and hot air is directly supplied to the textile product in the gap, There are problems that marks are likely to be formed on a portion corresponding to the width of the gap, which causes quality deterioration, and uniform thickness and hardness cannot be ensured. Further, this slat conveyor has problems such as meandering or vibration easily occurring, difficulty in speed control, and insufficient work efficiency.

Further, in a molding machine equipped with a wire net,
Since a gap is formed between the nets of the upper and lower net type endless belts and the hot air is directly supplied to the textile products in this gap, it is easy to put a mark on the part corresponding to the shape of the gap, which is a factor of quality deterioration. However, there are problems such as not being able to ensure uniform thickness and hardness.

[0007]

In view of the above, the present invention provides
The purpose is to be able to manufacture an unmarked product, or to obtain a product having a uniform thickness and hardness.

That is, the heat treatment molding machine for textiles of the present invention is
A transporting device for transporting a textile product including upper and lower endless belts having a perforation property, a motor and a rotating mechanism, and a hot air supply for supplying hot air to the textile product provided above the endless belt on the upper side of the transporting device. A device, an exhaust air suction device that faces the hot air supply device, and that is provided below the lower endless belt for sucking the air (exhaust air) that has finished working, and supplies the hot air to the hot air supply device. Hot air generating device, an air flow rate adjusting device attached to the exhaust air suction device, the thickness of the textile product provided at the end of the conveying device,
And a straightening roll group on the upper and lower sides for setting hardness.

[0009]

The function of the present invention will be described below.

At the same time as driving the upper and lower endless belts having a perforation property, the hot air supply device is turned on. Then, when the textile product is introduced between the starting ends of the both endless belts, the textile product is compressed by the upper and lower endless belts having the porosity and the perforation holes of the upper endless belt having the porosity. It is heat-treated by hot air supplied through. On the other hand, the hot air used for the heat treatment is cooled to some extent to become so-called finished air (exhaust air), and is then sucked into the exhaust air suction device. The supply device from the hot air supply device is individually controlled for each section, and the suction direction, the suction amount, etc. of the exhaust air suction device are appropriately selected via a damper attached to the exhaust air suction device. The optimum air temperature and air volume can be controlled. When the fiber product heat-treated by the above-mentioned operation and procedure (heat-processed fiber product) reaches the end of the upper and lower endless belts having the porosity, it is treated with cold air by the air supply device and at this end. The upper and lower straightening rolls provided and the upper and lower endless belt portions are pressed and delivered as a product having a predetermined thickness and hardness. Further, the upper endless belt and the upper roll group having the perforating property are moved up and down in the same plane position by using several jacks when the thickness, hardness, etc. of the product are changed.
