Among the instruments used as fishing gear, the materials such as the closed rope and the net are generally made of 100% PP material. These waste ropes and nets are disposed of in large quantities in fishing villages when they have reached the end of their useful life of about two years. The waste of the waste rope and the net generated at this time is large in quantity and is mixed with salt, seaweeds and shellfishes, And there is a limit to the recycling treatment because the processing and facility cost for the recycling treatment is high. Therefore, incineration treatment is often carried out for easy disposal. However, in this case, environmental pollutants are generated.

On the other hand, in the general industry, for example, in the automobile industry, restrictions on the production of lightweight, natural materials, and recycling are increasingly restricted. In Europe, by 2015, more than 95% of the automotive industry has to meet recycling standards.

Among the fishes used in fishing villages, netting and ropes, especially ropes, are used for aquaculture, berths, foresters and dots, and are collected and disposed twice a year to prevent environmental pollution. However, fishes used in fishing villages are difficult to recycle due to their high salinity, and even if they are recycled, they are easily broken by salt. Therefore, it is difficult to recycle and dispose of a large amount of waste rope every year, and the final disposal means is incineration, which causes environmental pollutants.

However, in this case, the facility cost and processing cost for re-processing are excessive, and the raw rope material is deformed due to heat, so that it is difficult to exhibit the desired properties, so that the value of recycling is lowered have.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has developed a method of releasing a waste rope without melting it to make a filament, and recycling it as various filament materials while maintaining rigidity of a raw material.

The polypropylene material of the pulp rope is flexible and soft, easy to work, has high strength, is not broken well, has abrasion resistance and durability, and is widely used for industrial, aquaculture, berths and dots lines, , We will replace the thermoplastic materials used in industrial widely used products such as building materials and automobile interior materials with the recycling of these pulp ropes.

The main constituent of the present invention is a method for producing a waste filament, comprising the steps of: collecting a closed rope made of polypropylene; Removing foreign matter adhered to the collected waste rope; Cutting the debris-removed waste rope; Washing the severed waste rope; Drying; And a filament forming step of disposing the closed rope in a rope disassembling device (30) into a filament form by disassembling the closed rope, characterized in that the moisture content rate in the drying step is 0 to 3% In the drying step, the drying method is characterized in that it is dried in superheated steam room using superheated steam.

A device characteristic of the present invention is that a feed conveyor (2) for feeding a cut waste rope, a feed roller (20) for feeding a cut waste rope coming in through the feed conveyor (2) And a rope disassembling device (30) for disassembling the supplied twisted waste rope.

Another embodiment of the apparatus of the present invention is a filament production apparatus utilizing a closed rope, comprising: a feed conveyor (2) for feeding the cut loose pulp; and a cutter for feeding the cut loose rope coming through the feed conveyor A cutter 50 having a rotary knife to make the supplied rope to be separated by a rotating blade and to be easily separated into filaments, And a rope disassembling device (30) for separating the closed rope into filaments by rotation of a main cylinder (24) equipped with a needle (26).

Another embodiment of the present invention is characterized in that it comprises a feed conveyor 2 for feeding the cut loose rope, a feed roller 20 for feeding the cut loose rope coming through the feed conveyor 2, A rope disassembling device 30 for separating the supplied rope into filaments by rotation of a main cylinder 24 having either a needle 26 or a saw blade on the outer periphery thereof, And a conveying conveyor 69 for conveying the fallen matter 64 of the filament mass which can not be adsorbed by the adsorption roller 60. The conveying conveyor 69 The short single yarn 65 of the filaments conveyed in the take-out rollers 66 further includes a moving roller 62 and a take-up roller 63 that drop to the bin 66.

Fig. 3 is a graph showing the relationship between the filament
Figures 4-8 illustrate other embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Among closed ropes, such as closed ropes and nets, the waste rope is almost 100% polypropylene. The present invention provides a filament manufacturing method and apparatus for a PP material using the same, and a filament by the apparatus.

The manufacturing process according to the present invention is as follows.

As shown in FIG. 1, the waste rope is collected to remove foreign materials such as crustaceans and cut by the standard. It is desirable to cut about 1-20 centimeters, for example, and easy to use for 5-8 centimeters, more preferably 6-7 centimeters. When cutting is performed, the pulp rope is naturally loosened to some extent during the process.

It is then washed to remove foreign matter and dried to a moisture content of 0 to 3%. Drying methods include gas and electricity drying methods, but they are disadvantageous in that the fuel cost becomes high. Another method is the natural drying method, which has a disadvantage in that the moisture content of the pulp rope is not rapidly reduced and the moisture content is not significantly lowered.

As a suitable drying method devised for this purpose, a drying method using heated steam can be used. Drying with superheated steam is more preferable because it is possible to perform decolorization, deodorization and cleaning function to remove saltiness. When the superheated steam is passed through the closed rope washed in the superheated steam room, superheated steam is injected from the superheated steam or from all directions, and then the evaporated and dried rapidly occurs. According to the superheated steam drying method, rapid drying is possible, the amount of heat required for drying is small, and the moisture drying efficiency is excellent at 2% or less.

Then, the fibers are disintegrated in a sequence of 1-10 times. Preferably about 3 to 8 times. The dismantling of the pulp rope is to untie the pulp rope that is twisted into several strands and to make it into the form of a thin thread of various kinds.

This is done in a disassembly device in which an operation of tearing the waste rope can be performed. The dismantling device is a device that can be torn by putting the waste rope material of the present invention into a filament form.

2, the main structure of the apparatus of the present invention includes a conveyor 2, a motor 8 for moving the conveyor 2, and a rake 3 installed on an end of the conveyor 2 An upper rotating body 6 having a rotating body 4 having a rotating shaft 4 and a rake 3 provided on the rotating body 4, a motor 10 for moving the rotating body 4, (3) of the rotating body (4) and a rake (3) of the upper rotating body (6), and a conveying conveyor (11) for feeding filaments of the waste rope (1) Are arranged so as not to collide with each other and to be placed at overlapping positions to perform a tearing operation. The rake 3 is formed in the shape of a letter "A", and two or three "A" -shaped protruding blades 13 are formed. The rotating body 4 and the upper rotating body 6 Is rotated in the direction of pulling up the inflow rope 1 and the inflated rope 1 flows into the height of the rotator 4 in a state of being vertically stacked to be torn.

When the closed loop 1 is introduced into the case 15 through a predetermined procedure in advance, the apparatus is processed so as to form a yarn-like filament. The reason why the waste rope must be torn without cutting is that the waste rope (1) itself must be processed into filaments, and if the filaments are excessively chipped, they do not have tough characteristics when applied to the material. That is, for example, when it is mixed with other automobile interior materials, it acts like reinforcing steel in reinforced concrete. If the filament is too thin and the length is cut short, it will not have the toughness characteristic, so the tearing process in the longitudinal direction of the material must be done.

In Fig. 2, when the lump of loose rope 1 continuously enters the conveyor 2, when the lump of loose rope 1 comes in, it enters the two rotors having the rake 3 formed therein. Then, the lower rotating body 4 is rotated clockwise in the figure and pulled up, and the upper rotating body 6 on the upper side is also rotated to the right. The entry of the waste rope 1 enters almost the formation height of the lower rotating body 4 and is pulled up by the rake 3 of the lower rotating body 4 and is pulled up. Then the upper rotating body (6) above picks up the raised rope and lifts it up. Therefore, the rotation of the rotating body (4) and the rotation of the upper rotating body (6) causes an operation to almost tear the closed rope (1). Particularly, the entering portion 5 between the rotating body 4 and the upper rotating body 6 has no gap in the receiving portion 5 because the rake 3 is staggered. Therefore, there is no waste rope 1 that passes through the inlet 5 of the collecting unit 5 at all, and the first tearing operation by the rotating body 4 and the second tearing operation by the next upper rotating body 6 are performed The pulp rope 1 is processed in a finely torn form and sent to the chute 7. Therefore, the waste rope 1 subjected to the first and second tearing operations is torn in the form of a filament.

In particular, the knurl 3 is formed in an "a" shape so as to facilitate the entry of the closed rope 1 and the "a" -shaped protruding blade 3 has at least two or more . If the protruding blades 13 are formed too much, it is appropriate to form about 2 to 3 pieces since the waste rope 1 is cut.

A motor 8 is installed in the lower part of the apparatus. The motor 8 drives the roller 9 to operate the conveyor 2 so that the closed rope 1 is continuously entered, while the other motor 10 rotates The entire body 4 and the upper rotating body 6 are operated and the feeder conveyer 11 is operated so that the filament finished pulley 1 is fed through the chute 7. [ The waste rope, which has been cut into filaments passing through the chute 7, can be used as materials for automobile interior materials and building materials by blending with other materials such as kenaf.

Needless to say, the apparatus can be processed into a filament shape using an apparatus of another structure as an example apparatus.

FIG. 3 illustrates a process in which the pulp rope disassembling operation is progressively repeated several times to gradually become thin and smooth fibers. Whether the rope is thick or thin, the rope rope is made by twisting a thread of propylene yarn in several strands, and by the operation of tearing out the rope, the rope can be made as thin as cotton. However, caution should be exercised so that boss yarn does not occur during marine operation. If bone scarring occurs, there is a problem that a malfunction occurs.

The waste rope dismantling process is performed to a thickness of about 1-30 denier, preferably about 4-15 denier. More preferably 7 to 8 denier is advantageous for the secondary processing. In other words, if the thickness of the fiber is small, it is easy to carry out secondary processing. For example, it is easy to mix with other fibers, to control the content of the blended fibers as desired, to control other processing phases, and to melt easily. However, if it is too thin, it is difficult to work it finely, and it has a disadvantage that it must go through various processes, and there may be a lot of fine blooms. If it is too thick, secondary processing and melting are difficult.

Hereinafter, another configuration of the pulley rope disassembling device illustrated in Fig. 2 will be described.

As shown in Fig. 4, when the cut waste rope enters, it is fed by a feed roller 20 made of rubber. At this time, when the support table 21 is provided under the feed roller 20, the lower loose load is supported and the frictional surface is provided, so that the supply of the pulleys can be more reliably and smoothly performed. The opened cutting rope is disassembled by the disassembling roller 23 and the e-mail cylinder 24.

The dismantling roller 23 has a projection 22 on its outer surface and a needle 26 is also formed on the outer surface of the mail cylinder 24. The needle is made of metal such as wire.

The dismantling roller 23 and the main cylinder 24 rotate in the same direction and perform a scraping operation at a mutual contact position. That is, at the position where the dismantling roller 23 and the main cylinder 24 are in contact with each other, when the disconnection roller 23 enters the disconnection roller 23, the dismounting roller 23 is lifted up. On the contrary, So that the twisted rope is dismantled. In this case, when the projections 22 are provided with inclined angles and the needles 26 are formed at the same inclination angle, they are scraped in mutually opposite directions at mutual contact positions, so that the disassembly of the closed ropes becomes stronger.

The needle 26 may have a protruding shape, and the protrusion 22 may have irregular or regular protrusion shape or gear tooth shape.

The dismantling roller 23 and the main cylinder 24 are configured in the box 29 to prevent the bufle or the like from spattering. The exhaust duct 28 can be installed and discharged.

The construction of the above-described pulley rope disassembling device can be constituted by a plurality of rows. In other words, at least one or more of the combination of the dismantling roller 23 and the main cylinder 24 may be arranged side by side so as to perform the dismantling of the pulleys in a continuous process. If the dismantling operation is performed only once, the thickness of the pulp rope is irregular, thick and coarse, but it can be rubbed with thin and fine surface while passing through several times.

On the other hand, the finely cut waste rope filaments falling through the waste rope disassembling device 30 are configured to be dropped downward in the conveying process of the conveyor 2, and can be input or removed in the re-input process. At this time, when there is metal or agglomerated material or foreign matter, the waste can be disposed by dropping it to the filter box 32 by using the weight difference.

The at least one pulp rope disassembling device 30 is made of a waste rope filament of a final desired thickness and is collected via a discharge roller 33. [

Fig. 5 is another embodiment of Fig.

In the embodiment of Fig. 5, the dismantling roller 23 is constituted by only one main cylinder 24, and the needles 26 made of wires are formed on the outer surface. The other cylindrical casing 32 is formed on the outer circumference of the main cylinder 24. [ The casing 32 is not necessarily cylindrical. Here, since the predetermined space is formed between the e-mail cylinder 24 and the casing 32, the closed rope is disassembled by rotation of the needle 26 between the gap between the e-mail cylinder 24 and the casing 32 will be. As in the previous embodiment, a plurality of the apparatuses can be installed side by side in a closed loop rope disassembling apparatus 30 having such a structure to produce a filament with fine and fine lines sequentially.

The feature of this embodiment is that the number of parts of the pulley rope disassembling device 30 is minimized. Further, the thickness of the closed rope can be further controlled by adjusting the number of revolutions of each main cylinder 24 to the closed rope disassembling device 30, which is installed in succession in succession. In other words, the pulley rope entering the initial stage of the pulley rope dismounting apparatus 30 is advantageous for making the finer filaments as the rotational speed of the main cylinder 24 becomes slower as the rotational speed of the main cylinder 24 increases.

Figure 6 is another embodiment.

In this embodiment, the feeding roller 20 is constituted by a pair of upper and lower rollers made of rubber, and the feeding and feeding of the closed rope to the feeding roller 20 is conducted to the feeding conveyor 41 in which the pin 40 is formed. According to the configuration of the supply conveyor 41 having the fins 40, it is possible to feed the slant to a desired position even on a slope. The waste rope dismounting device 30 in this embodiment is provided with a pair of dismantling rollers 23. The dismantling roller 23 constitutes a protrusion 23 on the outer surface thereof, and the protrusion is composed of a needle or a wire and is constituted by regular or irregular protrusions 23.

For example, it is not arranged side by side in a row, but may be arranged in various shapes such as a pattern shape, a wave shape, or a direction of a needle being different from each other, a shape of a lattice protrusion being different or irregular. Such an irregular or variable crimp configuration can result in uniform dismantling of the closed rope.

The projections 23 may be embossed concavely or convexly. If the projections 23 are directed in one direction in the circumferential direction, the disassembly of the closed ropes is better. The dismantling roller 23 disposed at the lower portion may not rotate as the rotating direction of the upper dismantling roller 23 but may rotate in the opposite direction.

7 is a modified embodiment of Fig.

As shown, the closed rope conveyed by the conveyor 2 is fed by the feed roller 20 and enters the cutter 50.

The cut 50 has a structure having about three rotating cutting blades, and cuts the twisted rope. These cutters are installed continuously about 2 or 3 times as needed, so that the pulleys are cut to a certain length.

It is preferable that about two pieces are preferably provided for practical use. The closed rope passing through the cutter 50 is in a state where it can be easily loosened to some extent, and the filament dismantling work of the rope is performed in the main cylinder 24.

A needle 26 protruding in the form of a wire is formed on the outer circumference of the main cylinder 24 so as to be separated into filaments so as to separate the waste rope. The main cylinder 24 is installed in the casing 32, and dust or fine scattered material is discharged through the exhaust duct 28. The rope disassembling apparatus 30 having such a structure can be installed side by side to be made into filaments gradually smaller in thickness.

Figure 8 is another embodiment.

As shown in the drawing, the closed loop introduced into the conveyor 2 enters the rollers 20

The feed roller 20 is formed with a projection 22 on its outer periphery

The projections 22 serve to push the closed rope, and the projections on the outer periphery are of sawtooth shape or various other protruding structures. The pulp rope supplied from the supply roller 20 is finely torn in the main cylinder 24 to form a filament. A needle 26 is formed on the outer periphery of the needle 26. The needle 26 may be formed of a wire or a saw blade. The separated waste rope is adsorbed on the adsorption roller 60 by the operation of the adsorption fan (not shown). An adsorption net 61 is formed on the outer periphery of the adsorption roll 60. The adsorption is performed on the surface of the adsorption roll 60 so that the filaments adhere to the adsorption net 61,

If the weighted filament, that is, the less separated bundle type filament, falls down by its own weight. In the lower part, a conveying conveyor 69 is installed to recycle the process. The dropped material 64 dropped by the weight is supplied again to the conveyor 2 via the take-up roller 63 via the take-up roller 62. In this case, the take-up roller 62 is transferred, The take-up roller 63 takes only a certain length of the filament and sends it to the conveyor 2, and does not need to take an extremely short single yarn, so it falls down by its own length so that the single yarn 65 is collected in the bin 66.

The constitution of the supply roller 20, the main cylinder 24, and the adsorption roller 60 may be provided in a plurality of sets successively, and the thin denier yarn can be pulled out gradually after the filament forming process is performed several times.

The dismounting means for dismantling the pulsing cutting waste rope according to the above embodiments is characterized in that a protruding shape such as a needle or a protrusion is formed on a cylindrical outer surface of a roller-like structure, This is the principle that the twist of the pulp rope is disassembled. Since various structural modifications employing these principles can be made in various forms, all such modifications are also to be construed as falling within the scope of the present invention.

In addition, the shape of the protrusions formed on the outer surface of the dismantling roller can be various shapes such as simple protrusions, hooks, inclined protrusions, needles, and metal wires, and the arrangement of such shapes can be formed in various forms such as irregularity, . In addition, rotation directions of the dismantling rollers can be arranged in various arrangements such as a forward direction and a reverse direction.

The installation of the above-described pulley rope disassembling apparatus 30 is the same as that of the above-described first to 10th apparatuses, and the pulley rope disassembling apparatus 30 performs the pulley rope disassembling operation 1 to 10 times. A plurality of waste rope disassembling apparatuses 30 may be installed, or a small number of waste rope disassembling apparatuses 30 may be installed and repeatedly circulated to perform a plurality of waste rope disassembly operations. Usually, it is optimal if the dismantling work in the waste rope disassembling device 30 is made into the 8-9 process. The yield of the closed rope is lowered, the loss of the material is large, and the thickness of the yarn is too small to be reused.

The polypropylene filament produced according to the present invention is made to be 1-30 denier scratches, preferably 7-8 denier depending on the use of cotton, civil engineering material, architectural drawing, automobile material and the like. For example, when it is a material for civil engineering work, it is necessary to make the waste rope disassembling device 30 through 4-5 times.

When the PP filament is produced by using the above-described manufacturing method, it is possible to utilize it as a material of civil engineering and building materials and a seat material of an automobile interior part, for example, in various industrial products which require PP material, It is possible to remarkably reduce the cost of materials, and it is possible to effectively recycle industrial wastes.
