TECHNICAL FIELD The present invention relates to a plumbing fixture system, and more particularly to an automated circumference for cutting a circumferential surface of a foam for drawing a plurality of pipes or conduits, and then introducing the pipes or conduits and extruding the coating according to the intended use. An integrated plumbing installation system.

Generally, a cable is a term used as a general term of an electric wire or the like. Cables are widely used for power and communication, and are classified into various types. Among them, CD pipes are typically embedded in manholes for cable entry and withdrawal of concrete structures or combined with inserts inside wire-protected pipes installed on the building floor, walls and ceilings during construction. Often wired.

These cables are usually separated from the pipes. Therefore, in the prior art, a method of first embedding a wiring protection pipe first, and then inserting a cable into the embedded pipe has been mainly used. In other words, the pipe was installed first, and then the cable was drawn in / out. However, in the conventional cable entry and withdrawal method, since the cable is pushed in from one side of the wiring protection pipe and pulled out from the other side, the cable installation work is quite complicated and difficult. In particular, when the pipe is bent buried in the structure of the structure, the difficulty of installation is further intensified, there was a problem that the total construction cost due to the delay of work time and the extension of the air increases.

In order to solve this problem, a cable integrated pipe has recently been developed. That is, as shown in Figs. 1 and 2, the cable-integrated pipe 1 has a plurality of cables 10 and a cable bundle binding port having a plurality of cable receiving portions 31 in which the cables 10 are accommodated. 30 and the protective pipe 50 which forms the external appearance so that the cable bundle bundling 30 may engage inside. Cable 10 is a generic term for electric wires and the like, in electrical and electronic systems, a conductor or bundle of conductors used to transfer electricity for power or communication from one place to another. Although the power cable and the communication cable differ in function and design structure, the protective film for protecting the inner conductor is similar. Protective coatings are usually made of aluminum or lead alloy tubes or a combination of metal tactile and thermoplastic materials to prevent safety accidents during the transmission of power or information.

Since the cable 10 having such a structure is wired at any place, it is necessary to organize a wiring structure by tying a plurality of cables 10 one by one, which is in charge of the cable bundle binding port 30. The cable bundle binding port 30 includes seven cable accommodation portions 31 in which seven cables 10 are accommodated, and a partition wall 35 extending radially from the center to form seven cable accommodation portions 31. ) And an iron core 37 in the longitudinal direction.

The cable bundle tie 30 of this structure accommodates the cables 10 so as not to contact each other. And, as shown in Figure 2, seven cable receiving portion 31 is arranged along the circumferential direction with respect to the center of the cable bundle binding port 30. Each cable receiving portion 31 has substantially the same area. The cable accommodating part 31 is formed by the partition wall 35 and partitioned into mutually independent spaces. Therefore, when the cables 10 are accommodated in a one-to-one correspondence with the cable receiving portion 31, the cables 10 are not in contact with each other. Each of the partition walls 35 extends radially at the center of the cable bundle engagement port 30 and then has a shape that is symmetrically curved in opposite directions at each end thereof. By the structure of the separating walls 35, the cable receiving portion 31 forms an annular shape.

However, the above-mentioned spacer walls may be suitable for stably accommodating a plurality of cables, but there is a problem in that a large amount of space is formed between the spacer walls and the protective film, thereby reducing the heat dissipation effect extremely. Such a cable protective film may be implemented as an exposed type or a buried type. The exposed type structure not only reduces heat dissipation effect but also decreases durability. . In addition, the conventional cable-integrated pipe has a problem that the artificial action is added to the assembly of the protective film and the spaced-off wall, the productivity is lowered.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an integrated piping equipment system that can realize an increase in productivity by providing an automated equipment for producing integrated piping.

Another object of the present invention is to provide an integrated piping installation system capable of minimizing the exothermic state of piping through PE crosslinked foaming to the outer circumferential surface of a plurality of pipes, wires.

As shown, a foam extruder 301 for foam molding with flame-retardant PE crosslinking or flame-retardant PE crosslinking to receive at least one or more pipes or (and) at least one conduit, a molding foamed in the foam extruder 301 Foam extruded from the primary cooling water tank 303 for cooling the water, the primary shunt wiper 305 for removing residual water in the primary cooling water tank 303, and the primary shunt wiper 305. An incision 307 for side-incision of the inlet of the pipe or conduit with respect to the foam, is installed in the proximal position of the incision 307 to continuously form the pipe or conduit in the form of a tube Winder 309, a straightener 311 for guiding the pipe or (and) conduit extruded from the winder 309 in a straight form, a pipe or (and) outflow from the straightener 311 Jig 313 for opening the incision surface of the foam to introduce the conduit into the foam, an assembly for pressing and introducing the pipe or (and) the conduit into the foam through the jig 313 ( 315), an adhesive 317 for joining the pipe or (and) conduit drawn into the foam, and a coating extruder 319 for forming a coating to the surface of the foamed product which is discharged through the adhesive 317. , A secondary cooling water tank 321 for cooling the surface temperature of the molding of the coating extruder 319, and a secondary shunt for removing residual water to the coating surface of the pipe drawn out from the secondary cooling water tank 321. The capperella 325 for pressurizing and drawing out the pipes generated by the second shunt wiper 323 and the end of the catapella 325 are interlocked to cut the draw pipe to a predetermined length. For cutting it consists of a group (327), the cutter (327) assembly winder 331 for winding the cut tubing to a finished product in the form.

The coating manufactured in the coating extruder 319 may be a foamed exterior coating, and a flame retardant composed of linear low density polyethylene (LLDPE) + ethylene vinyl acetate (EVA) may be used. This exterior coating has anti-oxidation and anti-UV functions, does not discolor, and has a product characteristic that is not harmful to the human body. In addition, polyvinyl chloride (PVC) may be used as the exterior coating of the coating extruder 319 in the present invention, which has an antioxidant, a sunscreen, a non-toxic additive, and has flame retardancy. In addition, it does not discolor, and there is no crack on the coating, which has an anti-oxidation function and is harmless to the human body.

In the piping system according to the present invention configured as described above, first, a plurality of copper tubes or (and) the conduit is foamed PE crosslinking is a synthetic resin by the foaming extruder (301). The foam extruder 301 is supplied into a cylinder heated by a synthetic resin such as polyethylene, polypropylene, polyester, and polystyrene and a heater, and the supplied synthetic resin is pressurized to the head by a pressure screw while being heated and melted in the cylinder. The synthetic resin solution pushed into the head is extruded into an extrusion mold while being continuously heated by a heater heating provided in the head. This foam is foamed to the outer circumferential surface of a plurality of copper tubes and conduits, the foamed resin will accommodate the copper tubes and conduits.

Thus, the foam extruder 301 is capable of continuous automated operation as the foam molding to the outer peripheral surface of the copper tube and the conduit. The above-described PE crosslinked foam is capable of flame retardant or flame retardant PE crosslinked foam, which may be selectively applied depending on the buried copper tube or the exposed copper tube.

The crosslinked foam for the copper tube and the conduit produced through the foam extruder 301 has a water cooling procedure by the primary cooling water passage 303. This is to quench the high temperature generated during the manufacture of the crosslinked foam, and is according to the low foaming method in which the raw material is foamed while being heated and cooled while putting a water support material mixed with a blowing agent into an extruder having a nozzle and extruding it. .

Thereafter, the primary shunt wiper 305 removes moisture remaining on the surface of the crosslinked foam cooled by the primary cooling water passage 303. Water removal is preferably using a high temperature air pressure. Accordingly, the primary shunt wiper 305 is connected to the rear end of the primary cooling water passage 303, and discharges air of a predetermined pressure to the outer peripheral surface of the crosslinked foam that has passed through the cooling water passage, thereby remaining water remaining on the outer peripheral surface of the crosslinked foam or Remove moisture If necessary, a predetermined temperature may be added to the discharged air, and for this purpose, a heater may be mounted as the air discharge port.

The incision 307 is a device for cutting the side of the foam-extruded foam, and cuts the pipe inlet formed into the foam as the foam supplied through the primary shunt wiper 305 as shown in FIG. The cutout portion of the foam is preferably an outer circumferential surface of the foam closest to the inlet, the center of the incision surface and the inlet can be set to have a perpendicular relationship with each other.

The foam cut in this way presses the at least one copper tube and the conduit to be introduced into the foam by the winder 309 and the straightener 311 in a straight form. Since the copper tube and the conduit are wound in a substantially circular shape, the copper tube and the conduit wound by the winder 309 and the straightener 311 are press-molded in a straight form. The winder 309 and the calibrator 311 is implemented in at least one pair or more depending on the number of copper tubes and conduits, one or more winders 309 and the calibrator 311 is driven at the same time a plurality of copper tubes and conduits At the same time, it is press-molded.

The winder 309 is a tube maker for manufacturing a synthetic resin pipe, and is made of an extrusion process. This tube making machine requires a cross-sectional shape of a material in which the synthetic resin material supplied to the hopper is heated in a heating cylinder, softened and melted, and kneaded and compressed by a rotating screw to form a uniform melted body. It is continuously extruded through a nozzle (nozel) made of die.

The raw material extruded through the die is continuously wound into a tubular shape while being wound on an outer surface of a winder (winder) forming a drum. If necessary, by cooling and curing with a water injector provided on the outside of the winder 301, it is possible to mass-produce synthetic resin tube products. When the winder 301 is equipped with a cooling function as described above, continuous production is achieved by continuously spraying water during the winding molding operation with a water injection device (not shown) to rapidly cure the raw material.

In addition, the corrector 311 has a structure in which the upper and lower work rolls are arranged in the main body, and the main cylinder is disposed in the upper frame of the main body. According to this configuration, while passing through a plurality of work rolls and pressurized by the main cylinder, a plurality of copper tubes are straightened and discharged.

The calibrator 311 is a device that presses at least one or more conduits, including at least one copper tube, to be discharged in a straight line, so that complex tubes such as copper tubes, communication tubes, and wires are maintained at regular intervals from each other. Therefore, the calibrator 311 may vary the structure of the work roll according to the number and size of the plurality of copper tubes and conduits.

On the other hand, at least one pair of copper tubes and conduits flowing out through the calibrator 311 is introduced into the foam, that is, the pipe inlet, the jig 313 sets the inlet position of the copper tubes and conduits. Thereafter, the copper tube and the conduit fed at a specific position by the assembly machine 315 are drawn in through the cutout of the foam. In addition, the foam including the copper tube and the conduit, that is, the foamed product, is sealed by the adhesive 317. The suture is in accordance with the heat treatment method by adhesive and heating. Here, the sealing method, including the above-described heat treatment method, there are a number of methods such as the adhesive method, the heating method, whichever method is used will not depart from the gist of the present invention.

And as described above, after the PE foam is made to the outer periphery of the plurality of copper tubes and conduits, the outer sheath is molded through the coating extruder (319). That is, chemicals mixed with LLDPE (Linear low density polyethy-lene) and EVA (Ethylene vinyl acetate) are foamed onto the outer circumferential surface of the PE foamed crosslinked foam. The LLDPE and EVA raw materials are flame retardants, antioxidants, UV-protective raw materials are added to the characteristics that do not burn, and do not discolor and does not crack the coating has an antioxidant function. It is also a non-toxic product that is harmless to the human body.

On the other hand, PVC (Poly vinyl chloride) may be used as the exterior coating of the coating extruder 319, which is an antioxidant, a sunscreen, a non-toxic additive is blended to exclude heavy metals, and has a characteristic that does not burn due to the flame retardant function. . In addition, there is no cracking phenomenon of the coating, and also has an anti-oxidation function, and has no features harmful to the human body.

Thus, since the coating extruder 319 foams to the surface of the PE foamed crosslinked foam, it may not be applied depending on the use of the pipe. In addition, the above-described coating extruder 319 winds the sheet in the form of a screw by the coating extruder 319 when the outer coating is an exposed sheet screw type. For example, the winder 319 may be applied when the air conditioner is installed in a structure to wind the tape in the form of a sheet to the outer circumferential surface of the crosslinked foam as shown in FIG. 5A. On the other hand, when the pipe is applied as a buried conduit, for example, when the power conduit is built in a corrugated pipe produced separately as shown in Figure 5b is not applied to the coating extruder 319 according to the invention.

When only the coating extruder 319 is applied in the present invention, the outer coat taken out from the coating extruder 319 cools the outer coating through the secondary cooling water tank 321. It is provided with at least one cooling tank (not shown) for cooling the coating extruded from the extrusion head of the coating extruder 319 for coating wire extrusion in the advancing direction of the coating. The cooling tank is a structure in which the resin coating is cooled by the cooling water on both inner sides of the front and rear surfaces. When the cooling is completed, the same drying process as the above-described process is performed by the secondary shunt wiper 323.

As described above, the second shunt shunt wiper 323 performs a drying process by air pressure in the same manner as the first shunt shunt wiper 305, and may start a heater to perform a high temperature drying operation as necessary. The catapella 325 interlocked at the rear end of the secondary shunt wiper 323 is a drawing device for continuously drawing a plurality of copper tubes or (and) conduits, so as to have a uniform tensile force without damaging the coating. Uniform tension is related to product quality, so uniform speed control is inevitable.

Thereafter, the cutter 327 is a device for cutting processing according to the consumer's requirements or the set length of the pipe, the assembly winder 331 is a device for loading the cut pipe in a predetermined form. Integral piping manufactured through such a procedure is packaged and then received and shipped.

As described above, the present invention has the effect of automatically foaming the blend of LLDPE + EVA or PVC to the outer circumferential surface of at least one copper tube or (and) conduit, thereby improving the production capacity of the pipe and lowering the unit cost. In addition, it is easy to transport the pipe by producing an integrated pipe, and also has an effect of shortening the construction period.
