Description

Technology Field

[0001] The present invention relates to a multi-pipe manufacturing device for air conditioners, and more specifically, to a multi-pipe manufacturing device for air conditioners that simplifies complex operations such as conventional adhesive application, heat fusion, and manual compression by implementing an integrated process of forming an incision line in an insulating tube, automatically inserting a multi-wire material inside, and then sequentially attaching double-sided tape and a finishing tape to seal it, and can improve the bonding strength of the incision part through the precise supply of double-sided tape by a first sealing module, uniform pressure by a conical roller of a compression part, and the attachment of a finishing tape by a second sealing module. Background Technology

[0003] Typically, air conditioning systems circulate refrigerant through pipes connecting the indoor and outdoor units. To prevent refrigerant loss and maintain efficiency, these piping systems are generally provided in the form of a multi-pipe assembly that integrates high-pressure pipes, low-pressure pipes, wires for communication and power supply, and drainage pipes with insulation.

[0004] One of the conventional methods for manufacturing multi-pipe bodies for air conditioners is known to be a technology in which high-pressure pipes and low-pressure pipes are inserted into insulation, and while transporting multiple insulation materials and multi-purpose pipes through a transport means, a portion of the insulation is cut and formed into a curved surface, then wrapped with a film and formed on the outside to manufacture the multi-pipe body. This technology produces a multi-pipe body for air conditioners by including a transport means, a cutting means, a forming means, a taping means, and a coating means of a multi-pipe body manufacturing device. In particular, a method is presented in which the contacting portion between insulation materials is cut and formed into a curved surface using a forming means, then wrapped with a film using a taping means, and a coating layer is formed on the outside using a coating means.

[0005] However, conventional methods and devices for manufacturing multi-pipe systems, including the aforementioned prior art, have the following problems. The cutting and joining processes of the insulation material require a complex structure, which leads to increased equipment and maintenance costs. Furthermore, it is difficult to guarantee perfect sealing using only methods such as simple adhesion or compression of the cut surfaces or wrapping with a film; consequently, there is a high likelihood of defects in the joining of the cut surfaces. Such defects can lead to a decrease in the insulation performance and weakened durability of the multi-pipe system, which in turn causes a decline in product quality.

[0006] Furthermore, due to the nature of conventional technology requiring complex process steps and precise control, it is difficult to avoid a decline in manufacturing productivity. In particular, there has been a problem where the overall production speed slows down because efficiency is reduced during the process of stably sealing and sealing the cuts in the insulation material. Therefore, there is an increasing demand for new methods and devices that can overcome these limitations of prior art and manufacture more efficient and robust multi-pipe bodies.

Furthermore, in describing the present invention, detailed descriptions of related known functions are omitted if they are deemed obvious to those skilled in the art and could unnecessarily obscure the essence of the invention.

[0020] FIG. 1 is a configuration diagram showing a multi-pipe manufacturing device for an air conditioner according to an embodiment of the present invention from a front view, FIG. 2 is a configuration diagram showing a multi-pipe manufacturing device for an air conditioner according to an embodiment of the present invention from a plan view, FIG. 3 is a cross-sectional view along line AA of FIG. 1, FIG. 4 is a cross-sectional view along line AA of FIG. 2, and FIG. 5 is a cross-sectional view along line BB of FIG. 1.

[0021] The present invention relates to a multi-pipe manufacturing device for an air conditioner, which is configured to include a tube feeding tube (10), a cutter (20), a wire insertion tube (30), an unloading tube (40), a first sealing module (50), a compression unit (60), and a second sealing module (70) so as to simplify complex operations such as conventional adhesive application, heat fusion, and manual compression by implementing an integrated process of forming a cut line in an insulating tube, automatically inserting a multi-wire material inside, and then sequentially attaching a double-sided tape and a finishing tape to seal it, and thereby improving the bonding strength of the cut portion through precise double-sided tape supply by the first sealing module, uniform pressure by a conical roller of the compression unit, and attachment of a finishing tape by the second sealing module.

[0022] The tube feeding pipe (10) according to the present invention is installed at a predetermined angle of inclination and performs the function of stably transporting an insulating tube (1).

[0023] The above tube feeding tube (10) is formed as a cylindrical tube and enables the smooth supply of the insulation tube (1) and movement to a subsequent process, thereby ensuring the continuity of the manufacturing process.

[0024] Additionally, the cutter (20) according to the present invention is installed inside the tube feeding tube (10) and forms a cutting line (1a) along the longitudinal direction of the insulation tube (1) being transported. This cutting line (1a) provides an insertion path for the multiple wires (2) through the wire insertion tube (30) described later.

[0025] In addition, the wire insertion tube (30) according to the present invention is arranged to form a predetermined angle of inclination with the tube feeding tube (10).

[0026] One end of the above-mentioned wire insertion tube (30) is received into the insulation tube (1) through a cut line (1a) formed in the insulation tube (1), and a funnel-shaped guide tube (31) is formed at the other end.

[0027] The above guide tube (31) guides the multi-wire material (2), including a high-pressure pipe, a low-pressure pipe, and a cable for an air conditioner, to be efficiently inserted into the insulation tube (1).

[0028] Accordingly, compared to the conventional multi-wire (2) input process using manual or complex mechanical processes, this simplifies and automates the manufacturing process, contributing to significantly improving productivity.

[0029] In addition, the unloading tube (40) according to the present invention is positioned in a straight line with the wire insertion tube (30).

[0030] And, the above unloading tube (40) serves to guide the stable movement of the insulation tube (1) into which the multi-wire (2) is inserted to a subsequent process.

[0031] In addition, the first sealing module (50) according to the present invention is positioned in the section where the cut line (1a) of the insulation tube (1) moves along the outer surface of the wire insertion tube (30), opens up, and then closes again.

[0032] The first suturing module (50) is configured to precisely insert a double-sided tape (T1) between the incision lines (1a) to join the two end surfaces of the incision lines (1a) together.

[0033] In FIG. 2, the first sealing module (50) includes a first supply bobbin (51) on which a double-sided tape (T1), with one adhesive surface finished by a release liner, is wound. Additionally, it is equipped with a guide roller (52) that is positioned in a straight line with the cutting line (1a) and guides the double-sided tape (T1) supplied through the first supply bobbin (51) to be fed into the cutting line (1a).

[0034] Then, the release liner on the double-sided tape (T1) that has passed through the guide roller (52) is separated from the recovery bobbin (53) and wound.

[0035] In this way, by precisely inserting the double-sided tape (T1) between the cut lines in the first sealing module (50), the cut lines can be precisely sealed and defects in bonding can be prevented.

[0036] Additionally, the compression part (60) according to the present invention is positioned between the first sealing module (50) and the unloading tube (40), and a pair of conical rollers (61) are provided to rotate in opposite directions to press the area of ​​the cut line (1a) into which the double-sided tape (T1) is inserted from both sides.

[0037] In FIG. 3, the conical roller (61) of the compression part (60) is formed with an arched curvature to correspond to the outer surface of the insulation tube, thereby uniformly pressing the cut portion to maximize the adhesive strength of the double-sided tape (T1) and further improve the bonding strength.

[0038] Additionally, the second sealing module (70) according to the present invention is positioned between the compression part (60) and the unloading tube (40) and is configured to attach a finishing tape (T2) to the outer surface area of ​​the insulation tube (1) including the cut line (1a).

[0039] In FIG. 1, the second sealing module (70) includes a second supply bobbin (71) on which a finishing tape (T2) having an adhesive surface formed on one side is wound, and a compression roller (72) positioned between a conical roller (61) and an unloading tube (40) to press-attach the finishing tape (T2) to an outer surface area of ​​an insulating tube (1) including the cutting line (1a) in a straight line with the cutting line (1a).

[0040] In this way, the additional attachment of the above-mentioned finishing tape (T2) forms a double seal structure in the cut area, preventing bonding defects and significantly improving the durability of the insulation tube.

[0041] In addition, the double-sided tape (T1) and the finishing tape (T2) are connected in a 'T' shape by the connecting adhesive module (80) to more firmly seal the area of ​​the insulation tube (1) separated by the cut line (1a).

[0042] The above-mentioned linked adhesive module (80) includes an expanded adhesive piece (81) formed such that one end of the double-sided tape (T1), which is fed through the guide roller (52) into the cutting line (1a), protrudes relative to the outer diameter of the insulation tube (1); an annular groove (82) formed in intaglio on the outer surface of a pair of conical rollers (61) corresponding to the expanded adhesive piece (81), and forming a non-contact space (82a) between the pair of conical rollers (61) and the expanded adhesive piece (81); and an air nozzle (83) disposed between the conical rollers (61) and the compression roller (72), which sprays compressed air in a direction perpendicular to the insulation tube (1) to bend the expanded adhesive piece (81) in the circumferential direction of the insulation tube (1).

[0043] And, as shown in Fig. 4, the expansion adhesive piece (81) is bent in the circumferential direction of the insulation tube (1) by the compressed air output through the air nozzle (83), and the finishing tape (T2) supplied through the second sealing module (70) is attached to the outer surface area of ​​the insulation tube (1) separated by the expansion adhesive piece (81) and the cut line (1a).

[0044] In this way, the ‘T’-shaped connection structure of the double-sided tape (T1) and the finishing tape (T2) mechanically reinforces the seam around the cut line, thereby significantly enhancing airtightness and mechanical strength, and minimizes the degradation of thermal insulation performance or separation during long-term use, thereby increasing the reliability of the product.

[0045] In addition, the present invention is composed of modules that integrate the process from the insertion of multi-wires to the suturing of the incision line, thereby minimizing separate worker intervention and facilitating easy application to automated lines; thus, it is suitable for mass production systems and effectively reduces manufacturing costs.

[0046] In particular, it forms a seam while preventing damage or deformation to the outer surface of the insulation tube, maintains excellent appearance quality through a 'T'-shaped reinforcement structure, and ensures the reliability of the seam, enabling effective prevention of problems such as condensation, heat loss, and mechanical failure after installation.

[0047] In conclusion, the multi-pipe manufacturing device for air conditioners according to the present invention forms an incision line on an insulating tube, automatically inserts a multi-wire, and then prevents bonding defects and improves durability through a multi-stage sealing process using double-sided tape and finishing tape. Furthermore, it is possible to reduce manufacturing costs and maximize productivity by enhancing airtightness and mechanical strength through a 'T'-shaped connection structure, as well as by automating the process and increasing efficiency.

Accordingly, the scope of protection of the present invention should not be limited to the above embodiment, but should be recognized to include the technologies of the claims described below and equivalent technical means derived from these technologies.
