Description

[Detailed Description of the Invention] In order to make the ship, ship, etc. all the more convenient by contributing to the investment of the sloppy wood clippings to substantially reduce the size of the seven valley beaches. Regarding the equipment, the packaging, and the packaging that was produced in the 7th century.

Previous attempts to compress bulky textile products, such as compressible consumer textile products, to facilitate their shipping and storage have not been sufficiently commercialized. Uke has not been accepted. This is because many such products, when left in a compressed state for a period of time, develop semi-hydroplastic or permanent) or creases, stilts or permanent fibrous sets. Such wrinkles, creases, and compression of the fibers can be used for consumer sales or other uses.
li products may be made unreasonable. To reduce this waste, the moisture content of consumer textile products is first reduced, then placed in moisture-tight packaging, and then the volume is reduced (if necessary). -1: It was proposed to exhaust the air.To explain in detail, 5hiqh:
- Q in the rice vines given to Mr. 3, Valve No. 3961458 and I5I No. 4199916; exposing the textile material for a long time to an air-conditioned environment with low relative humidity;
It has been proposed to reduce the moisture content by subsequently vacuum packaging the material. No. 4,199,916 proposes air conditioning by passing textile material through a tunnel. This tunnel has a temperature of 20 to 30℃ and a temperature of 15℃.
The first treatment zone is kept at a relative humidity of ~3096° C. and the second stabilization zone is kept at a temperature of 15-20° C. and a relative humidity of 5-12%. Processing times in the tunnel are long as a necessary consequence of bringing the moisture level in the fabric into equilibrium with the relative humidity of the conditioned air. The patent states that up to 240 minutes are required.

As is clear from the above, the two 5hisho.

The method disclosed in his patent is not fully satisfactory from a commercial point of view, as it requires lengthy processing times, which severely limits production output.

Moreover, in order to reduce the relative humidity of the air to the required low 7 to quasi 1, which also controls the temperature of the air being conditioned,
Furthermore, a great deal of energy, energy, and equipment power is required, and the products must be processed in open, wide-shelf racks. However, it is practically impossible to obtain a very low moisture content in textile products, even 10% lower than the normal moisture content of textiles. This is because prohibitive conditioning times would be required in air of extremely low relative humidity.

Accordingly, it is an uninvented object to provide a commercially viable method and apparatus for packaging textile products in a compressed state to reduce their volume and facilitate handling, shipping and storage.

Provided is an apparatus and apparatus for packaging textile products under compression, characterized in that the textile products are substantially free of water-encroaching particles, folds or fiber compression sets when the packaging is opened. This is one detailed purpose of invention X.

Almost all the indications in the Example 7 product were evaluated so as to maximize the beneficial results achieved by the absence of moisture, yet require only a short period of time and a relatively low level of energy. It is also an object of the present invention to provide the above-mentioned method and device for scissoring, which utilizes the processing space.

To provide a package of a compressible textile product, which is compressed by at least 50% of the natural volume of the textile product and has a moisture content of not more than 10% of the moisture content of its open cavity. is yet another uninvented object.

These and other uninvented objects and advantages include: (2) at an energy level and time sufficient to evaporate at least a major portion, preferably substantially all, of the water in the water;
applying microwave energy to the textile product;
The method and apparatus described herein include the steps of immediately compressing the textile product and packaging the compressed product in a substantially vapor-impermeable enclosure that maintains its compressed condition. It's a shame, but it will be done in the future. - The heated air is passed through the drying step by step across the surface of the product and the textile product.

It is preferable to accelerate the removal of hydrated water and to accelerate the drying process.

It has been discovered that the uninvented use of micro membranes to evaporate moisture in textile materials yields several significant benefits. In particular, microwave energy rapidly heats and evaporates moisture in textile materials, typically about 2 to 3 minutes.
It has been found that the processing time is significantly reduced by 1 minute.

Moreover, since the microwave energy effectively drives evaporated moisture from the interior of the textile material, the moisture is readily removed from the outer surface of the material by the energized constant air flow passing through it. Therefore, ventilation is not necessary to penetrate into the interior of the item to carry away the moisture. This is a significant advantage, since it minimizes the amount of ventilation and allows many textile products to be processed in a folded and unfolded state. It may be folded into an extinguisher-sized bag, and the processed package may be further
It is in a form that can be packaged immediately without being handled or handled. And to deal with it again! 'iThis may cause undesirable water recovery. The use of generated microwave energy is believed to reduce energy consumption within conventional heating methods and remove virtually all moisture from the entire interior of the textile material without the risk of overheating or damaging the textile material. It can be removed quickly and uniformly. Bota,
Equipment associated with the use of microwave energy requires minimal space and is relatively inexpensive.

Some of the objects and advantages of the invention have been mentioned above, and others will become apparent as the description proceeds in conjunction with the accompanying drawings.

Looking at the drawings in more detail, the first drawing shows the basic elements and weights of one embodiment of the great invention.
7) However, it should be understood that the invention can equally be applied to packaging any type of textile product that can be used for other applications.

As used herein, "compressible textile articles" are sleepers, quilted bedspreads, towels, or clothing.
as well as bulk fibers and non-woven fabrics, which may be made of either natural fibers or synthetic 'fki =i. K in the case of relatively wide forgiveness/goods
fd, it is preferred that they be folded into a consumer size prior to processing and packaging, as described in detail below.

According to the described embodiment of the invention, the textile product or material 12 to be packaged is moved forward through the long housing sink or tunnel, and this j. The tunnel 14 is typically about 45 feet long and has an upper running surface 17 extending horizontally through the tunnel to support the product 12 thereon. It includes an endless perforated conveyor 16 having a The tunnel 14 includes an entrance end 4!20 and an exit end 21, each having a relatively low height on the order of about 4 inches;
It is designed to prevent microwave energy from escaping through the tunnel.

The tunnel further contains a hot air duct system 22. Therein is preferably an electric heater or the like for about 1 hour.
Preheated outside air at 10 to 140" F. is forced through the tunnel laterally and across the surface of the product. Air tact equipment is typically 10,000" F.
The upper part 17 of the air belt 17 is moved upward by 3 times: it enters from the side of the tunnel and then is discharged from the tunnel to the bond ( (See Figure 3). The flowing stream of heated air carries away evaporated moisture from the product, thus helping to speed up the drying time while maintaining a relatively cool temperature inside the product. In some cases, the vapor content of the air is preferably not reduced before being circulated through the tunnel, so that the air contains almost all of the ambient water vapor. If desired, the entire air may be recirculated to minimize heat loss, but it may be necessary to introduce a sufficient amount of outside air to limit the build-up of water vapor in the recirculated air. .

The second endless perforated conveyor 24 is located so as to be spaced apart from the upper running part 17 of the lower conveyor extending through the tunnel, so that the second endless perforated conveyor 24 is spaced apart from the upper running part 17 of the conveyer, which extends through the tunnel. 20 and outlet end 21 to support and contact the fabric 12 during passage through each of them. The upper conveyor 24 thus serves to compress the Tachibana product as it passes through the narrow inlet and outlet end sections.

The output device that generates the micro-temporal power within the tunnel 14 is generally conventional, such as the Model IV-3.
Microdry Corporation as Q-8
of San Raman (California)
It may consist of a device manufactured by. The output device is typically designed to produce a microwave power of 30 x 1 at 915 MHz, and this frequency is that assigned to commercial heating equipment by the FCC (Federal Communications Commission). ) Also, the design of the inlet end 20 and upper end 21 of the sump to prevent leakage of microwave power is conventional, for example, in U.S. Pat. No. 38,580 to Smith.
Please refer to No. 22.

The speeds of conveyors 16 and 24 and the level of microwave energy are such that the moisture content of the product is preferably reduced by less than 10-6 of its ongoing content.
And the product is qualitatively dry, and it is determined that the product will be reduced by 1, 8, 2, 5 (Sere 7, n).

In the described apparatus 52, the product 12 is placed in this tunnel 14 for about 2-3 minutes in order to achieve this reduction in moisture content.
Stay within. The microwave energy also serves to raise the temperature of the textile product itself by a limited amount, but not enough to cause damage to the product. It should be understood that typically the temperature of the material is raised by about 140-150 kg, and the amount of temperature increase will also depend on the initial moisture content of the material.

Upon exiting the microwave tunnel 14, a dried product 12
is immediately directed to charging device 30, as best seen in FIGS. 4 and 5. This device contains a feeding device with co-operating conveyors 32, 33, a second cut and a charging device. The automatic bagging device is made of a suitable plastic bag 37, which is stacked 36, and as the product is packed, the top bag is opened; Contains a lever arm that allows the base paper to be rolled in a circular shape for advancing with the Connovator 421.
3 may be positioned so as to compress each product or its associated material when entering it. In this way smaller and therefore cheaper bags can be used.

From the charging container 30, the product 12 and the enclosing bag 37 are advanced to a compression and sealing device 44. A flat 'fi 46 is then lowered onto each product by means of a suitable pneumatic piston ram 47 or the like.

The force of the ram acts to compress the product well and
or to at least 50% of its original volume, and in the case of further compressible products such as pillows as shown in the figures, about 20-30% of its original volume. A certain amount of co-edition may be drawn to facilitate compression of the product and remove residual air. A heat sealing rod 48 is fitted onto the front edge of plate 46 and is lowered automatically by piston 49. At that time, the product is in a plastic bag.
3fl! If the end is sealed with hot straw, it is in a state of failure (Section 7).

Upper 2 6''-approximately, pressure rises, product 5
0 is kept in its fertilized state by the bag 37.

′! ! Additionally, the material of the bag is chosen to have a very low permeability to water vapor, so that it can effectively prevent moisture from returning to the interior of the product for a sufficient period of time. - For example, polyethylene sheets are commercially available in a number of grades with different water vapor transmission rates. Since the material with the lowest permeability is that much more expensive, the textile product should first be placed in a cheaper material with a relatively high permeability.
It is conceivable to package each package separately and then repackage some of such packages into a material with very low vapor permeability. Alternatively, one or more of the resulting bulk items can be prepared for shipping by placing them between upper and lower sheets of corrugated paper and threading the sheets together with suitable strings. In this way, the amount of corrugated paper used in the outer 1u11 can be minimized.

] Between 1 and 4, it is the fourth precept. When he opened the package, he said: This is a certain amount of g, and there is always 6 r.These are not very saturated, and do not require pressing or other processing. , it usually disappears once sufficient moisture has been restored. 2. At least about 50% to 6% of the nitric acid required for such recovery.
It should have a relative humidity of 0%, preferably higher. This is because the higher the relative humidity, the faster complete water recovery and recovery of original shape and volume will occur.

The drawings and illustrations clearly show the advantages of the present invention. Although a new embodiment has been described and specific terminology is used, they are used in a general descriptive sense and are not intended for exclusive purposes. So there is no Sith.
