1 is a schematic view showing a zipper bag molding apparatus 1 according to an embodiment of the present disclosure, FIG. 2 is a perspective view showing an extrusion unit 10 according to an embodiment of the present disclosure, and FIG. 3 is one of the present disclosure. It is a cross-sectional side view showing the coupling part 50 according to the embodiment, and FIG. 4 is a perspective view showing a manufactured zipper bag (Z) according to an embodiment of the present disclosure.

The zipper bag forming apparatus 1 compresses and molds the zipper bag Z, aligns it, and combines the coupling grooves Z1 and coupling protrusions Z2 formed on the zipper bag Z with each other to manufacture the zipper bag Z.

Specifically, the zipper bag molding apparatus 1 is formed by placing an upper portion of the extrusion unit 10 for compressing and molding a zipper bag Z having a coupling groove Z1 and a coupling protrusion Z2, and the extrusion unit 10. The first tensioning unit 20 that air-cools the zipper bag Z and pulls it upward, and is disposed below the first tensioning unit 20 to move the zipper bag Z moved from the first tensioning unit 20 to the lower side. The second tension unit 30, the alignment unit 40 disposed below the second tension unit 30 to align the coupling groove Z1 and the coupling protrusion Z2, and the alignment unit 40, The coupling part 50 and the extrusion part 10, which press and couple the coupling groove Z1 and the coupling protrusion Z2, are connected to the aligning unit 40 and the coupling unit 50, so that the extrusion unit 10 and the aligning unit 40 and the processor 2 controlling the coupling unit 50, a light emitting unit 71 disposed below the coupling unit 50 to radiate laser toward the zipper bag Z, and a light receiving unit to receive the irradiated laser beam (72) may be included.

As disclosed in FIG. 2 , the extrusion unit 10 may mold the zipper bag Z by extruding the zipper bag Z at a high temperature (about 180 degrees). Here, the molded zipper bag (Z) may have coupling grooves (Z1) and coupling protrusions (Z2) formed at the same time.

Specifically, the extrusion unit 10 is configured to include an extrusion die 11 having an annular hollow portion and an annular extrusion core 12 installed through the hollow portion of the extrusion die 11, the extrusion die ( 11) may include an injection unit 13 for injecting the molten plastic material between the inner wall and the outer wall of the extrusion core 12.

Here, the extrusion die 11 may be formed in a shape corresponding to the coupling groove Z1 and the coupling protrusion Z2.

Accordingly, as the molten plastic melt passes through the space between the extrusion die 11 and the extrusion core 12 and the shape formed on the extrusion core 12, it is molded into the shape of a zipper bag (Z) and can move upward.

The first tension unit 20 is disposed above the extrusion unit 10 to move the zipper bag Z molded in the extrusion unit 10 upward. At this time, as the zipper bag (Z) moves upward, the shape of the molded zipper bag (Z) may be maintained by air cooling.

The first tension unit 20 may have a variety of structures capable of continuously moving the molded zipper bag (Z) upward and guiding it to the second tension unit 30 at the same time. For example, the first tension unit 20 may include a roll.

The second tension unit 30 is located at the rear end of the first tension unit 20 in terms of the process, and the molded zipper bag Z delivered from the first tension unit 20 is transferred to the lower portion adjacent to the second tension unit 30. It can be delivered to the alignment unit 40 located in.

The second tension unit 30 can prevent the zipper bag Z from sagging or sagging by applying a certain level of tension to the zipper bag Z molded together with the first tension unit 20 .

The second tension unit 30 may have a variety of structures capable of guiding the zipper bag Z to the alignment unit 40 . For example, the second tension unit 30 may include a roll.

The alignment unit 40 is located below the second tension unit 30 and primarily presses the zipper bag Z moved in the second tension unit 30 so that the coupling groove Z1 and the coupling protrusion Z2 are mutually connected. They can be arranged so that they are placed adjacent to each other in facing positions.

At this time, the zipper bags (Z) formed in a cylindrical shape may be deformed into a shape in which mutually facing surfaces overlap each other through the alignment unit 40.

The alignment unit 40 may have a variety of structures that can press the facing surfaces to contact a certain portion of the spaced apart zipper bags (Z). For example, the alignment unit 40 may include a pair of rolls arranged to face each other adjacently.

Accordingly, the zipper bag (Z) can pass between the aligning parts 40 of the pair of rolls and align the coupling groove (Z1) and the coupling protrusion (Z2) to face each other.

The coupling part 50 may press the coupling groove Z1 and the coupling protrusion Z2 of the aligned zipper bag Z arranged under the alignment unit 40 so that they are coupled to each other. For example, the coupling portion 50 is a zipper bag Z in a groove formed between the first coupling portions 50-1 and 50 and the second coupling portions 50-2 and 50 disposed adjacent to each other. By passing through the coupling groove (Z1) and the coupling projection (Z2), the coupling projection (Z2) can be pressed so as to be inserted into the coupling groove (Z1).

The processor 2 is inherent in the zipper bag forming apparatus 1 and can control the overall operation of the zipper bag forming apparatus 1.

Here, the processor 2 is a central processing unit (CPU), a controller, an application processor 2 (application processor (AP)), or a communication processor 2 (communication processor (CP)), an ARM processor (2) may include one or more of them.

The rotary part 60 is located below the coupling part 50 and continuously winds the zipper bag Z in which the coupling groove Z1 and the coupling protrusion Z2 are mutually coupled to each other and can be maintained in the form of a roll. Here, the rotation unit 60 may provide power to move the zipper bag Z molded in the extrusion unit 10 .

The light emitting part 71 and the light receiving part 72 are located below the coupling part 50, and it is possible to measure whether the coupling protrusion Z2 and the coupling groove Z1 are coupled. That is, the light emitting unit 71 irradiates a laser beam to the coupling protrusion Z2 and the coupling groove Z1, and the light receiving unit 72 absorbs the laser beam passing through the coupling projection Z2 and the coupling groove Z1 to produce a refracted laser beam. The laser value can be measured.

The light emitting unit 71 and the light receiving unit 72 may be disposed to face each other.

Specifically, the processor 2 irradiates a laser beam from the light emitting unit 71 to pass through the coupling groove Z1 and the coupling projection Z2, and emits light passing through the coupling groove Z1 and the coupling projection Z2. By receiving it in the light receiving unit 72, it is possible to determine whether the coupling groove Z1 and the coupling protrusion Z2 are coupled.

Here, determining whether to combine is to compare the distribution of laser values received in the light receiver 72 with the reference laser distribution stored in the processor 2, and if the difference in shape is within the error range, it is determined that the coupling is successful and the zipper bag (Z ) can be performed continuously.

On the other hand, if the distribution of laser values received in the light receiver 72 is compared with the reference laser distribution stored in the processor 2, and the difference in shape exceeds the error range, there is an abnormality in the coupling or the coupling groove Z1 and the coupling groove Z1. When it is determined that the protrusion Z2 is separated, it may be controlled to notify the user.

Accordingly, in the zipper bag forming apparatus 1 according to an embodiment of the present disclosure, when the zipper bag Z is incorrectly formed or there is an abnormality in the coupling between the coupling groove Z1 and the coupling protrusion Z2 of the zipper bag Z. Edo process progresses to prevent the continuous occurrence of defects and at the same time to prevent the user from constantly checking for defects, thereby improving the user's efficiency and at the same time greatly improving the manufacturing efficiency of zipper bag (Z) molding through a stable process. can make it

Hereinafter, with reference to FIGS. 5 to 8, a zipper bag forming apparatus 1′ according to another embodiment of the present disclosure will be described.

Here, the same reference numerals are used for the same components, and overlapping descriptions are omitted. For example, since the extrusion unit 10, the first tension unit 20, the second tension unit 30, the alignment unit 40, and the rotation unit 60 are the same as those described above, overlapping descriptions will be omitted.

The zipper bag forming apparatus 1′ according to another embodiment of the present disclosure includes a measuring unit disposed between the aligning unit 40 and the coupling unit 50′ and irradiating the line laser L toward the zipper bag Z ( 80) may be further included.

Specifically, the measurement unit 80 includes an irradiation unit 81 that irradiates the line laser L in the width direction toward the zipper bag Z and a detection unit that detects the line laser L passing through the zipper bag Z ( 82) may be included. Here, the measurement unit 80 and the detection unit 82 may be arranged to face each other.

The irradiation unit 81 may include a device for irradiating a conventional line laser (L).

The sensing unit 82 may include a plurality of sensors for sensing the line laser (L).

The measuring unit 80 irradiates the line laser (L) in the width direction of the zipper bag (Z) to the zipper bag (Z) passing through the measuring unit 80, and measures the value of the line laser (L) passing through the zipper bag (Z). It can be measured and transmitted to the processor 2.

Accordingly, the processor 2 determines whether or not there is an abnormality and thickness of the coupling groove Z1 and coupling protrusion Z2 of the molded zipper bag Z based on the transmitted line laser L value of the measuring unit 80. It can be determined by calculation, and then the first adsorption pressure and the second adsorption pressure of the coupling part 50' can be determined using the calculated thickness.

In addition, the coupling part 50' rotates in contact with the zipper bag Z, and is disposed to face the first curved roll 53 formed to have a larger diameter toward the center and the first curved roll 53, and is disposed to face the zipper bag ( Z) may include a second curved roll 54 that rotates in contact with and is formed to have a smaller diameter toward the center.

Here, the first curved roll 53 and the second curved roll 54 are disposed to face each other and may have complementary shapes. In addition, the distance between the first curved roll 53 and the second curved roll 54 may be smaller than the distance between the aligning unit 40 .

The first curved roll 53 may have a shape in which a central portion protrudes through a shape in which a diameter increases toward the central portion. In addition, the first curved roll 53 may press the first portion Z10 of the zipper bag Z in contact with the first portion Z10 of the zipper bag Z in which the coupling groove Z1 is formed.

Accordingly, the first curved roll 53 can easily open the coupling groove Z1 outward through the convexly curved center portion so that the coupling protrusion Z2 is inserted therein.

Meanwhile, the second curved roll 54 may have a concave shape at the center through a shape in which the diameter decreases toward the center. In addition, the second curved roll 54 may press the second portion Z20 of the zipper bag Z in contact with the second portion Z20 of the zipper bag Z having the coupling protrusion Z2 formed thereon.

Therefore, the first curved roll 53 and the second curved roll 54 contact and press the first part Z10 and the second part Z20 of the zipper bag Z according to the mutually complementary shapes, so that the coupling protrusion By using the structure in which (Z2) is widened, the coupling stability and coupling efficiency of the coupling groove (Z1) and the coupling protrusion (Z2) can be further improved.

In addition, the first curved roll 53 is formed at a predetermined interval along the surface of the first curved roll 53 to adsorb the adjacent zipper bag Z. The first suction port 53a and the first suction port ( 53a) may include first suction passages 53b for sucking air through the first suction holes 53a.

The first suction holes 53a may be formed at predetermined intervals along the outer circumferential surface of the first curved roll 53 . That is, a plurality of first suction ports 53a may be provided.

The first suction passage 53b is independently connected to the first suction port 53a so that an independent suction pressure for the first suction port 53a can be adjusted. For example, the first suction passage 53b may be in the form of a separate nozzle of the first curved roll 53 or a passage structurally drilled through the first curved roll 53 .

The first suction passage 53b is connected to an external suction driving source (not shown) so that the suction pressure can be adjusted.

In addition, the second curved roll 54 is formed along the surface of the second curved roll 54 at a predetermined interval and includes a second suction port 54a and a second suction port (54a) that adsorb adjacent zipper bags (Z). 54a) may include second suction passages 54b for sucking air through the second suction holes 54a.

The second suction holes 54a may be formed at predetermined intervals along the outer circumferential surface of the second curved roll 54 . That is, a plurality of second suction ports 54a may be provided.

The second suction flow path is independently connected to the second suction port 54a so that an independent adsorption pressure for the second suction port 54a can be adjusted. For example, the second suction passage 54b may be in the form of a separate nozzle of the second curved roll 54 or a passage structurally drilled through the second curved roll 54 .

The second suction passage 54b is connected to an external suction driving source (not shown) so that the suction pressure can be adjusted.

Through the above structure, the processor 2 can determine the intensity of the line laser (L) based on the molding information of the molded zipper bag (Z) input by the user. Here, the molding information of the zipper bag (Z) may include the thickness and transmittance of the zipper bag (Z).

Thereafter, the processor 2 may irradiate the line laser L toward the zipper bag Z through the irradiation unit 81 with the determined intensity of the line laser L. For example, the intensity of the line laser L may increase as the thickness increases and may decrease as transmittance increases.

Accordingly, the processor 2 measures the zipper bag (Z) for the zipper bag (Z) having various thicknesses and materials by examining the line sizer of strength suitable for the molding information of the zipper bag (Z) input by the user. can be performed.

Next, the processor 2 calculates the calculated thickness based on the value of the line laser (L) detected through the sensor 82, and calculates the calculated thickness and the thickness of the molded zipper bag (Z) input by the user. It is possible to determine whether there is an abnormality in the thickness of the molded zipper bag (Z) by comparison.

Specifically, when the calculated thickness exceeds the error range of the thickness of the molded zipper bag (Z) input by the user, it is determined that there is an abnormality in the thickness of the molded zipper bag (Z), and the processor 2, Various alarm devices (emergency sound, etc.) can be controlled to notify the user and stop the extruding part 10, the aligning part 40, and the coupling part 50.

Accordingly, unlike the molding information input by the user, the zipper bag forming apparatus 1' detects in real time whether or not there is an abnormality in the thickness of the molded zipper bag Z and informs the user or stops the process, thereby erroneously manufacturing the zipper bag ( Z) can be prevented from being continuously produced, and the user's work efficiency can be greatly improved.

On the other hand, the processor 2 compares the line laser (L) value detected through the sensing unit 82 and the stored line laser (L) value to determine whether the formed coupling groove (Z1) and coupling protrusion (Z2) are abnormal. can judge

For example, the processor 2 includes the line laser (L) value including the distribution, intensity, etc. of the line laser (L) sensed through the detector 82 and the line laser (L) previously stored in the processor By comparing the values, if the detected line laser (L) value exceeds the error range of the pre-stored line laser (L) value, it is determined that there is an abnormality in the formed coupling groove (Z1) and coupling protrusion (Z2). can

Here, the pre-stored line laser (L) value is the line laser (L) recognized by the sensing unit 82 when the line laser (L) refracts and passes through the normally formed coupling groove (Z1) and coupling protrusion (Z2). It can mean the distribution and intensity of.

Thereafter, when the processor 2 determines that there is an abnormality in the coupling groove Z1 and the coupling protrusion Z2, the processor 2 notifies the user and stops the extrusion unit 10, the alignment unit 40, and the coupling unit 50. You can control it.

Accordingly, the zipper bag forming apparatus 1` detects in real time whether or not the coupling groove Z1 and coupling protrusion Z2 of the molded zipper bag Z are abnormal, informs the user, or stops the process, thereby erroneously manufacturing the zipper bag. (Z) can be prevented from being continuously produced, and the user's work efficiency can be greatly improved.

At the same time, the processor 2 may determine the first area S1 and the second area S2 based on the value of the line laser L sensed through the sensor 82 . Here, the zipper bag Z passing through the measuring unit 80 has a first region S1 where the coupling groove Z1 and the coupling protrusion Z2 are located and a second region located at the edge of the first region S1. (S2) may be included.

For example, the processor 2 moves the coupling protrusion Z2 from the zipper bag Z based on the value of the line laser L detected by the detector 82 for the zipper bag Z passing through the detector 82. And it is possible to determine the position where the coupling groove (Z1) is formed. Specifically, the processor 2 detects the line laser (L) in the sensing unit 82 suitable for the line laser (L) value according to the positions of the coupling protrusion (Z2) and the coupling groove (Z1) previously stored in the processor (2). ) values, it is possible to determine the location where the coupling protrusion Z2 and the coupling groove Z1 are formed in the zipper bag Z.

Thereafter, the processor 2 determines the first adsorption pressure of the first area S1 and the second area S2 adsorbed by the first curved roll 53 and the second curved roll 54 based on the calculated thickness. The second adsorption pressure of can be determined. Here, as the determined calculated thickness increases, the first adsorption pressure and the second adsorption pressure increase, and the first adsorption pressure may be greater than the second adsorption pressure.

Thereafter, the processor 2 adsorbs the zipper bag Z through the first curved roll 53 and the second curved roll 54 with the determined first adsorption pressure and the second adsorption pressure, and at the same time, the coupling groove Z1 And the coupling protrusion (Z2) can be coupled.

Accordingly, the zipper bag forming apparatus 1` adjusts the first adsorption pressure and the second adsorption pressure corresponding to various thicknesses, thereby stably adsorbing the zipper bag Z having various thicknesses to improve manufacturing efficiency and adsorption at the same time. The required power consumption can be minimized.

In addition, the zipper bag forming apparatus 1′ forms a larger first adsorption pressure for the first region S1 where the coupling groove Z1 and the coupling protrusion Z2 are coupled to the coupling groove of the zipper bag Z ( Through physical fixation of the region where Z1) and coupling projection Z2 are located, the stability of coupling between coupling groove Z1 and coupling projection Z2 can be greatly improved, and the second adsorption pressure can be applied to adjacent regions. By adjusting the adsorption pressure to the first curved roll 53 and the second curved roll 54, the area adjacent to the curved shape is prevented from being rolled or overlapped, further improving the adhesion of the zipper bag (Z) to the zipper bag (Z). It is possible to further improve the coupling efficiency of the coupling groove (Z1) and the coupling projection (Z2) of.

In this specification, only a few examples of various embodiments performed by the present inventors are described, but the technical spirit of the present invention is not limited or limited thereto, and can be modified and implemented in various ways by those skilled in the art, of course.
