Description

Perforated flux pipe manufacturing apparatus

The present invention relates to an apparatus for manufacturing a porous outlet pipe, and more particularly, to an apparatus for manufacturing a porous outlet pipe that can be used to manufacture a porous outlet pipe included in a filter device.

A filter device is a device that purifies a fluid. Such a filter device may include a porous outlet pipe and a separator. The bonding method of the porous outlet pipe and the separation membrane is, for example, first winding a protective film on each of both ends of the porous outlet pipe. Here, the protective film may be a release paper for easy attachment and detachment of a general sticker.

Continuing to describe the bonding method of the porous outlet pipe and the separator, an adhesive tape for fixing the protective film to the porous outlet pipe is attached so that a portion does not overlap the protective film. Next, an adhesive material is applied to the circumferential surface of the porous outlet pipe, and then the fabric used as a separator is wound around the porous outlet pipe.

Then, each of both ends of the separation membrane wound on the porous outlet pipe is cut by a predetermined length. The cut separator is removed from the porous outlet tube.

The conventional method of bonding the porous outlet pipe and the separator as described above involves a process of aligning the positions of the protective film and the adhesive tape to be attached to the porous outlet pipe, and a process of cutting the protective film and the adhesive tape at regular lengths. , there is a problem in that productivity decreases as the manufacturing time is long.

In addition, a lifting phenomenon occurs in the portion where the adhesive tape is not overlapped in the protective film, and the adhesive material moves to the portion where the protective film is lifted and remains on the peripheral surface of the porous outlet pipe, thereby causing defects.

Korean Patent Registration No. 10-1397296

An embodiment of the present invention is to provide an apparatus for manufacturing a porous outlet pipe that can reduce the manufacturing time.

The apparatus for manufacturing a porous outlet pipe according to an aspect of the present invention includes a supply unit for discharging a plurality of stored porous outlet pipes to the outside one by one, a transport unit for transporting the porous outlet pipe discharged from the supply unit to another location, and the transfer and at least one attachment unit for attaching a protective tape to the porous outlet pipe transported by the unit, wherein the protective tape has a length so that an edge of one surface is adhered to the porous outlet pipe.

In this case, the attachment unit includes a first winding part on which a release paper is wound to which the protective tape is spaced apart at regular intervals, and a separation part positioned adjacent to the first winding part to separate the protective tapes attached to the release paper one by one. , a second winding part on which the release paper from which the protective tape is separated is wound, and a part of the protective tape separated from the separation part by rotating the porous outlet pipe in contact with the porous outlet pipe transported by the transfer unit is released from the porous outlet It may include a contact portion to be attached to the peripheral surface of one end of the tube.

In this case, there are two attachment units, and the two attachment units may be located opposite to each other with respect to the transfer unit.

In this case, one of the two attachment units may be located closer to the supply unit than the other attachment unit.

In this case, the protective tape may include a base portion having one end of one edge formed to be inclined, and an adhesive portion formed along an edge of a surface in contact with the porous outlet pipe in the base portion.

In this case, the base part may be made of polypropylene (PP).

In this case, one end of the base part may be inclined as it moves away from the adhesive part.

In this case, the inclination angle of the inclined portion of the base portion may be included in the range of 30° to 80° with respect to the longitudinal direction of the bonding portion.

In this case, the width of the adhesive portion may be included in the range of 3mm to 7mm.

In this case, the adhesive part may be a double-sided tape adhered to the base part.

In this case, the adhesive part may be formed by applying an adhesive material to the base part.

The apparatus for manufacturing a porous outlet pipe according to an embodiment of the present invention includes a supply unit, a transfer unit, and an attachment unit, so that a protective tape formed so that the edge of one side is adhered to the porous outlet pipe can be quickly attached to the porous outlet pipe.

In this way, since the protective tape can be quickly attached to the porous outlet pipe when the porous outlet pipe is manufactured, the production per unit time is increased compared to the conventional porous outlet pipe manufacturing apparatus that attaches a protective film and an adhesive tape to the porous outlet pipe, respectively. Accordingly, productivity can be significantly improved.

For example, in the conventional apparatus for manufacturing a porous outlet pipe, a protective film and an adhesive tape are attached to 5 to 7 porous outlet pipes per minute. A protective tape can be attached to up to 100 porous outlet tubes.

In addition, since one edge of one end of the base part included in the protective tape is inclined, one end of the base part may be prevented from being lifted from the porous outlet pipe while the protective tape is attached to the porous outlet pipe. Accordingly, it is possible to prevent the adhesive material from flowing into the peripheral surfaces of both ends of the porous outlet pipe while the adhesive material for attaching the separator is applied to the porous outlet pipe.

In addition, various processes can be sequentially performed during the manufacturing of the filter device. As described above, the lifting phenomenon of the base is prevented, so that the protective tape is not damaged from external contact in the process of transferring the object produced in each process to another step. This may allow for reliable handling of the porous outlet pipe to which the protective tape is adhered.

In addition, after the separation membrane is wound on the porous outlet pipe, both ends of the separation membrane are cut by a predetermined length, and then, in the process of removing the remaining separation membrane, the separation membrane removal operation can be performed smoothly by the protective tape.

In addition, when the protective film and the adhesive tape are respectively attached to the porous outlet pipe using the conventional apparatus for manufacturing a porous outlet pipe, bending (step difference) may occur while the adhesive tape or a portion of the protective film is folded. However, in the apparatus for manufacturing a porous outlet pipe according to an embodiment of the present invention, a portion of the protective tape is not folded and adhered while closely adhering to the circumferential surface of the porous outlet pipe, thereby preventing bending (step difference) from occurring in a portion of the protective tape. Therefore, it is possible to reduce the defect rate in manufacturing the filter device.

However, the arrangement relationship of the through holes 11a is not limited thereto and may be arranged in various ways. Such a through hole 11a allows the fluid introduced into the porous outlet pipe 11 to be discharged to the outside during the operation of the filter device 10 described above, or to allow an external fluid to flow into the porous outlet pipe 11 . do.

The separation membrane 12 is wound around the outer peripheral surface of the porous outlet pipe 11 . Two such separators 12 may be provided, and since the two separators 12 overlap each other to form a pocket shape, a detailed description thereof will be omitted.

Since the separation membrane 12 and the housing 13 may be a separation membrane and a housing included in a general filter device, a detailed description thereof will be omitted.

The porous outlet pipe 11 is located at the center of the filter device 10 and may be installed to cross along the longitudinal direction. The porous outlet pipe 11 may allow the fluid introduced from the outside to flow into the separation membrane 12 surrounding the outer circumferential surface while being transported along the longitudinal direction.

In the manufacturing process of the filter device 10 having such a structure, an adhesive material is applied to the circumferential surface of the porous outlet pipe 11 , and the fabric serving as the separator 12 is wound around the porous outlet pipe 11 .

3 and 4 , the apparatus 100 for manufacturing a porous outlet pipe according to an embodiment of the present invention includes a supply unit 110 , a transfer unit 120 , and an attachment unit 130 .

The supply unit 110 discharges the stored plurality of porous outlet pipes 11 one by one to the outside. The supply unit 110 may include, for example, a receiving unit 111 and a rotating unit 112 . The accommodating part 111 includes an internal space. A plurality of porous outlet pipes 11 may be accommodated in the inner space. One side of the accommodating part 111 may be located adjacent to the transfer unit 120 to be described later.

The rotating part 112 may be located on one side of the lower end of the accommodating part 111 . To this end, one side of the lower end of the accommodating part 111 may be formed to be open. The rotating part 112 may be positioned to be upwardly spaced apart from the transfer unit 120 .

The shape of the rotating part 112 may be, for example, a cylindrical shape. A plurality of receiving grooves may be formed on the circumferential surface of the rotating part 112 . One porous outlet pipe 11 may be accommodated in one receiving groove. When the rotating part 112 rotates, the porous outlet pipe 11 accommodated in the receiving groove may fall to the transfer unit 120 .

The transfer unit 120 transfers the porous outlet pipe 11 discharged from the supply unit 110 to another location. The transfer unit 120 may be, for example, a plurality of rollers connected to each other so as to be rotatable at regular intervals. A porous outlet pipe 11 may be positioned on two rollers adjacent to each other.

The attachment unit 130 attaches the protective tape 140 to the porous outlet pipe 11 transferred by the transfer unit 120 . There may be two such attachment units 130 . In this case, the two attachment units 130a and 130b may be located opposite to each other with respect to the transfer unit 120 . Each of the two attachment units 130a and 130b attaches the protective tape 140 to each of both ends of the porous outlet pipe 11 .

In addition, one of the two attachment units 130a and 130b may be located closer to the supply unit 110 than the other attachment unit 130b.

5 is a view showing an attachment unit extracted from the porous outlet pipe manufacturing apparatus of FIG. 4 , FIG. 6 is a view showing a state in which a protective tape is attached to the porous outlet pipe by the attachment unit, and FIGS. 7 to 9 is a diagram sequentially illustrating a process in which the protective tape is attached to the porous outlet pipe by the attachment unit.

5 to 9 , the attachment unit 130 may include, for example, a first winding part 131 , a separating part 132 , a second winding part 133 , and a close contact part 134 .

In the first winding unit 131 , the release paper 150 to which the protective tape 140 is spaced apart from each other is wound. A protective tape 140 is adhered to one surface of the release paper 150 . On the surface of the release paper 150 to which the protective tape 140 is adhered, an adhesive part 142 to be described later of the protective tape 140 is attached thereto, and a coating layer (not shown) that can be easily separated may be formed. As the coating layer, any adhesive layer such as a sticker may be used as long as it can be separated. Here, a detailed description of the protective tape 140 will be omitted.

When the first winding unit 131 rotates in one direction while the release paper 150 is wound around the first winding unit 131 , the release paper 150 is unwound from the first winding unit 131 .

The separation unit 132 is positioned adjacent to the first winding unit 131 to separate the protective tape 140 attached to the release paper 150 one by one. The shape of the separation unit 132 may be, for example, a triangular shape. An end of the triangular-shaped separator 132 may be rounded. Due to the shape of the separation unit 132 , the release paper 150 may smoothly pass through the rounded portion while unwinding from the first winding unit 131 .

In addition, since the radius of curvature of the end of the separation unit 132 is very small, a portion of the release paper 150 located at the end of the separation unit 132 is rapidly bent and the protective tape 140 is removed from the release paper 150 . can be easily removed.

In the second winding unit 133 , the release paper 150 from which the protective tape 140 is separated is wound. The second winding unit 133 and the first winding unit 131 may have a structure similar to each other. For example, the structure of the second winding unit 133 and the first winding unit 131 may include, for example, a roller and a rotation motor. A release paper is wound on the roller. The rotary motor rotates the rollers.

The contact portion 134 is in contact with the porous outlet pipe 11, a portion of which is transferred by the transfer unit 120 . The adhesion part 134 rotates the porous outlet pipe 11 so that the protective tape 140 separated from the separating part 132 is attached to the peripheral surface of one end of the porous outlet pipe 11 .

The adhesion part 134 for this purpose may include a plurality of rollers R and a belt V, for example. A plurality of rollers (R) may be spaced apart from each other. The belt (V) may be positioned to surround the plurality of rollers (R).

When at least one roller (R) of the plurality of rollers (R) is rotated by a motor (not shown), the belt (V) is rotated. When the porous outlet pipe 11 comes into contact with the rotating belt V while being transported, it may be rotated in one direction. At this time, the protective tape 140 separated from the release paper 150 by the separation unit 132 may be attached to the rotating porous outlet pipe 11 .

That is, the protective tape 140 is separated from the release paper 150 and supplied one by one between the belt V and the porous outlet pipe 11 while the belt V is continuously rotating. It can be attached to the circumferential surface.

Here, the protective tape 140 may be simultaneously attached to both ends of the porous outlet pipe 11 , and the protective tape 140 is attached to one end of the porous outlet pipe 11 and then the protective tape 140 to the other end. It may also be possible to attach.

Meanwhile, the above-described attachment unit 130 may further include a tension maintaining unit 135 . The tension maintaining part 135 may be positioned adjacent to the first winding part 131 , and positioned so as to be in contact with one side of the release paper 150 .

The tension maintaining unit 135 constantly maintains the tension of the release paper 150 so that the release paper 150 can maintain a taut state between the first winding unit 131 and the second winding unit 133 . By maintaining the release paper 150 in a taut state as described above, the protective tape 140 may be stably separated from the release paper 150 by the separation unit 132 .

On the other hand, in the apparatus 100 for manufacturing a porous outlet pipe according to an embodiment of the present invention, the protective tape 140 attached to the porous outlet pipe 11 has a length so that the edge of one side is adhered to the porous outlet pipe 11 . formed to be The length of the protective tape 140 may be, for example, a length such that the peripheral surface of the object is not exposed to the outside while the object is wrapped.

FIG. 10 is a view illustrating a release paper and a protective tape wound on a first winding unit in the attachment unit of FIG. 5 , and FIG. 11 is a view illustrating a protective tape attached to the release paper of FIG. 10 at regular intervals.

10 and 11 , the protective tape 140 as described above may be adhered to both ends of the porous outlet pipe 11 , respectively. The protective tape 140 for this purpose may include, for example, a base portion 141 and an adhesive portion 142 .

The base part 141 is formed so that any one edge of one end is inclined. For example, the base portion 141 may have a triangular shape at one end. In more detail, one end of the base part 141 may be inclined as it moves away from the adhesive part 142 . For example, the inclination angle A of the inclined portion L of the base portion 141 may be included in the range of 30° to 80° with respect to the longitudinal direction of the adhesive portion 142 .

At this time, when the inclination angle (A) of the inclined portion (L) in the base portion 141 is less than 30˚, the area of the base portion 141 is excessively reduced and thus the porous outlet pipe 11 cannot be wrapped, so that the porous outlet pipe ( In the process of applying the adhesive material to the surface of 11), the adhesive material may be applied to a portion of the porous outlet pipe 11 that should not be applied. Alternatively, when the inclination angle A of the inclined portion L of the base portion 141 exceeds 80°, it may be difficult to prevent a lifted shape at the edge of the base portion 141 .

As described above, since any one edge of the base part 141 is formed to be inclined, one end of the base part 141 is attached to the porous outlet pipe 11 while the protective tape 140 is attached to the porous outlet pipe 11 . 11) can be prevented. Accordingly, it is possible to prevent the adhesive material from flowing into the peripheral surfaces of both ends of the porous outlet pipe 11 while the adhesive material for attaching the separator 12 is applied to the porous outlet pipe 11 .

Meanwhile, various processes may be sequentially performed when the filter device 10 is manufactured. As described above, the lifting phenomenon of the base part 141 is prevented, so that the protective tape 140 is not damaged from external contact in the process of transporting the porous outlet pipe 11 to another place for another process to be protected. Stable handling of the tape 140 and the porous outlet 11 may be possible.

On the other hand, the above-described base portion 141 may be made of polypropylene (PP: polypropylene). Polypropylene is a polymer of propylene. Polypropylene has excellent chemical resistance, durability and heat resistance. Polypropylene, which has one more carbon atom, is polymerized to produce polypropylene, which is transparent and more resistant to refraction than polyethylene.

As described above, since the protective tape 140 is made of polypropylene having excellent mechanical properties, it can be neatly cut in the process of being cut together with the separator 12 , so that cutting reliability can be improved.

The adhesive part 142 is formed along the edge of the surface in contact with the porous outlet pipe 11 in the base part 141 . The width of the adhesive portion 142 may be included in the range of 3 mm to 7 mm, for example. The method of forming the adhesive part 142 may be, for example, a double-sided tape adhered to the base part 141 . Alternatively, the method of forming the adhesive part 142 may include applying an adhesive material to the base part 141 as another example.

Such an adhesive part 142 allows the protective tape 140 to be stably adhered to the porous outlet pipe 11 . In the process of transferring the porous outlet pipe 11 to another location, the adhesive part 142 may prevent the protective tape 140 from being separated from the porous outlet pipe 11 .

As shown in FIG. 12 , each of the two protective tapes 140 may be wound around the porous outlet pipe 11 so that the adhesive part 142 faces the center of the porous outlet pipe 11 . Accordingly, in the process of removing a portion of the separation membrane 12 wound on the porous outlet pipe 11 for manufacturing the filter device 10 , the separation membrane 12 that is cut and remaining is removed by the protective tape 140 through the porous outlet pipe. It can be easily separated from (11).

As described above, the porous outlet pipe manufacturing apparatus 100 according to an embodiment of the present invention includes a supply unit 110 , a transfer unit 120 , and an attachment unit 130 , so that the edge of one side is the porous outlet pipe 11 . ), the protective tape 140 formed to be adhered to the porous outlet pipe 11 can be quickly attached.

As described above, when the porous outlet pipe 11 is manufactured, the protective tape 140 can be quickly attached to the porous outlet pipe 11 , so the conventional porous outlet for attaching the protective film and the adhesive tape to the porous outlet pipe 11 , respectively. As the production per unit time is increased as compared with the tube manufacturing apparatus, the productivity can be significantly improved.

For example, in the conventional apparatus for manufacturing a porous outlet pipe, a protective film and an adhesive tape are attached to 5 to 7 porous outlet pipes 11 per minute, but the apparatus for manufacturing a porous outlet pipe according to an embodiment of the present invention described above ( 100) may attach the protective tape 140 to 80 to 100 porous outlet pipes 11 per minute.

In addition, since the base part 141 included in the protective tape 140 is formed with an inclined edge at one end, the base part 141 in a state in which the protective tape 140 is attached to the porous outlet pipe 11 . ) can be prevented from being lifted from one end of the porous outlet pipe 11 . Accordingly, it is possible to prevent the adhesive material from flowing into the peripheral surfaces of both ends of the porous outlet pipe 11 while the adhesive material for attaching the separator 12 is applied to the porous outlet pipe 11 .

In addition, various processes may be sequentially performed during the manufacturing of the filter device 10 , and as described above, the lifting phenomenon of the base part 141 is prevented, so that the protective tape in the process of transferring the object produced in each process to another step Since the 140 is not damaged from external contact, it is possible to stably handle the porous outlet pipe 11 to which the protective tape 140 is adhered.

Then, after the separation membrane 12 is wound on the porous outlet pipe 11, both ends of the separation membrane 12 are cut by a predetermined length, and then the separation membrane 12 is removed by the protective tape 140 in the process of removing the remaining separation membrane 12. 12) The removal operation can be performed smoothly.

In addition, when the protective film and the adhesive tape are respectively attached to the porous outlet pipe 11 using the conventional apparatus for manufacturing a porous outlet pipe, bending (step difference) may occur while the adhesive tape or a portion of the protective film is folded. However, in the apparatus 100 for manufacturing a porous outlet pipe according to an embodiment of the present invention, a portion of the protective tape 140 is adhered while being in close contact with the circumferential surface of the porous outlet pipe 11 without being folded, so that the protective tape 140 is Since it is possible to prevent bending (step difference) from occurring in a portion, it is possible to reduce the defect rate in manufacturing the filter device 10 .

Although various embodiments of the present invention have been described above, the drawings and detailed description of the described invention referenced so far are merely exemplary of the present invention, which are only used for the purpose of explaining the present invention and are not limited in meaning or claimed It is not used to limit the scope of the invention described in the scope. Therefore, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom.
