1 to 7 , the pouch-type package manufacturing system 100 according to an embodiment of the present invention is largely a film supply unit 110 , a first thermal bonding unit 120 , and a first cooling progress unit 130 . , the second thermal bonding proceeding unit 140 , the second cooling proceeding unit 150 , the additional processing proceeding unit 160 , and the cutting unit 170 may be included.

First, the film supply unit 110 supplies the film 1 in the direction of the first thermal bonding progress unit 120 to be described later, and cuts the film 1 in the longitudinal direction at the same time as the supply so that the two cut sides face each other. It plays a role in merging.

More specifically, referring to FIG. 2 , the film supply unit 110 is connected to the winding shaft 111 on which the film 1 is wound, the winding shaft 111, and the film wound on the winding shaft 111 through length adjustment ( 1) a pair of tension control cylinders 112 for adjusting the tension of the first, changing the direction of movement of the film 1 unwound from the winding shaft 111 by bending it at various angles (eg, 90 degrees angle) The angle adjustment bar 113, the blade 114 for cutting the film 1 whose supply direction is changed in the longitudinal direction to separate it into two halves into the first side 1a and the second side 1b, the first separated from each other The second and third adjustment bars (115, 116) and the first surface (1a) and the second and third adjustment bars (115, 116) and the first surface ( 1a) and the second surface 1b may be laminated to face each other and may include a lamination roller 117 for supplying them in the direction of the first thermal bonding progress unit 120 .

The winding shaft 111 may have a variable shaft outer diameter using pneumatic pressure, and may be flexibly fitted with respect to the inner diameter of the roll wick on which the film 1 is wound.

Both end portions of the winding shaft 111 may be rotated while being mounted on the frame in a horizontal direction. At this time, a pair of tension control cylinders 112 provided at both end portions of the winding shaft 110 adjust the length of the piston rod according to the real-time tension value of the film 1 unwound from the winding shaft 111 to adjust the length of the film 1 ) to keep the tension value constant at all times.

The film 1 unwound from the winding shaft 111 proceeds toward the first thermal bonding proceeding portion 120 by a plurality of rollers, wherein the film 1 refers to the main material of the pouch-type package. Here, the pouch-type package may refer to various types of film wrapping paper, such as a wrapping paper for masks or stockings, a standing-type wrapping paper that can stand on its own, a zipper-processing wrapping paper, and the like.

At this time, since the film 1 wound on the winding shaft 111 is a method in which both sides of the pouch-type package are printed at once and supplied in an in-line form, it is cut in the longitudinal direction to face each other. need to do

To this end, the film supply unit 110 changes the moving direction of the film 1 by bending at a specific angle through one or more first angle adjustment bars 113 .

More specifically, the film 1 that advances in the upward direction through a plurality of rollers is changed to a state in which the printing surface is bent at an angle of 90 degrees by the first first angle adjustment bar 113a. The film 1 is directed toward the blade 114 by changing the direction in a U-turn manner by the roller in the traveling direction. In this case, a sensor for sensing the center in real time based on the width direction of the film 1 may be provided at the center of the film 1 . Accordingly, when it is determined that the center of the film 1 moving toward the blade 114 is not aligned as a result of the sensing, in the present invention, a signal to inform that the center is not aligned may be output through a separate alarm device.

The blade 114 is positioned at the center with respect to the width direction of the film 1 in progress, and at this time, the film 1 is automatically bisected as the film 1 moves past the blade 114 .

At this time, the film 1 is divided into a first surface 1a and a second surface 1b. In the present invention, for convenience, the surface in which the traveling direction is bent upward through the second angle adjustment bar 115 is removed. The first surface 1a, the surface in which the traveling direction is bent in the downward direction through the third angle adjustment bar 116 will be referred to as the second surface 1b.

The first surface 1a is bent at an angle of 90 degrees upward by the second angle adjustment bar 115, and the bent first surface 1a is U-turned by a roller in the traveling direction. This is changed and comes down again. At this time, the printing surface is located on the upper side of the first surface (1a).

The second surface 1b is bent at an angle of 90 degrees downward by the third angle adjustment bar 116, and the bent second surface 1b is a U-turn by the roller in the traveling direction. This is changed and comes back up to the top. At this time, the printing surface is positioned below the second surface 1b.

That is, the first surface 1a and the second surface 1b passing through the second angle adjustment bar 115 and the third angle adjustment bar 116 are printed surfaces before being supplied to the first thermal bonding progress unit 120 . These are opposite to each other so as to be positioned in opposite directions. Thereafter, the film supply unit 110 adheres the first side 1a and the second side 1b to each other through a roller to be laminated. Currently, the first surface 1a and the second surface 1b are in close contact with each other, and are in a state before thermal bonding is performed.

The first thermal bonding proceeding unit 120 is linearly reciprocated in the vertical direction corresponding to the moving speed (advance speed) of the first surface 1a at the upper portion of the first surface 1a proceeding through the film supply unit 110 . By doing so, thermal bonding proceeds in the longitudinal direction of the first surface 1a.

It may be configured to include a first linear movement device 122 for reciprocating linear movement.

The heating bar 121 may be disposed to face the longitudinal direction of the currently proceeding first surface 1a, and may be heated to a temperature for thermally bonding the first surface 1a and the second surface 1b to each other. have. In this case, the heating is achieved through the supply of electricity.

The heating bar 121 is reciprocally linearly moved in the vertical direction by the first linear movement device 122. At this time, the first linear movement device 122 moves the first surface 1a and the second surface 1b. The heating bar 121 is moved in a straight line through pneumatic pressure in accordance with the speed (travel speed). For example, after pressing the heating bar 121 using pneumatic pressure in the downward direction, the pressure is momentarily removed. At this time, a plurality of elastic bodies (springs) connected between the heating bar 121 and the first linear movement device 122 . ) by the elastic force of the heating bar 121 is returned to the upper direction again. Accordingly, the first linear movement device 122 repeats the above process according to the movement speed (advance speed) of the first surface 1a and the second surface 1b.

The first cooling proceeding portion 130 is located at the rear end of the first thermal bonding proceeding portion 120 described above, and is formed on the upper portion of the first surface 1a in the same manner as the first thermal bonding proceeding portion 120 . It serves to cool the joint area.

The first cooling progress unit 130 is located on the upper portion of the first surface 1a and includes a cooling bar 131 that maintains a state of being cooled by a refrigerant circulating through a refrigerant circulation passage provided therein, and a cooling bar ( 131) may be configured to include a second linear movement device 132 for reciprocating linear movement in the vertical direction.

The cooling bar 131 is disposed to face the longitudinal direction of the currently proceeding first surface 1a, and in particular, may be disposed at a position corresponding to the heating bar 121 described above. Accordingly, as the thermal bonding portion is formed on the first surface 1a by the heating bar 121 , the cooling bar 121 cools the thermal bonding portion. At this time, the cooling bar 131 may maintain a cooled state to a temperature for sufficiently cooling the thermal bonding portion.

The cooling bar 131 is reciprocated and linearly moved in the vertical direction by the second linear movement device 132, in which case the second linear movement device 132 moves the first surface 1a and the second surface 1b. The cooling bar 131 is moved in a straight line through pneumatic pressure in accordance with the speed (advance speed). For example, after pressing the cooling bar 131 in the downward direction using pneumatic pressure, the pressure is momentarily removed. At this time, a plurality of elastic bodies (springs) connected between the cooling bar 131 and the second linear movement device 132 . ) by the elastic force of the cooling bar 131 is returned to the upper direction again. Accordingly, the second linear movement device 132 repeatedly performs the above process according to the movement speed (advance speed) of the first surface 1a and the second surface 1b.

The second thermal bonding proceeding part 140 moves in the vertical direction in accordance with the moving speed (advance speed) of the first surface 1a from the upper portion of the first surface 1a to correspond to the first thermal bonding proceeding portion 120 described above. The thermal bonding proceeds in the width direction of the first surface 1a by linear reciprocating movement.

More specifically, referring to FIG. 4 , the second thermal bonding progress unit 140 is located on the first surface 1a, and a plurality of heating bars 141 are arranged at regular intervals and each is heated by a heater. ) and the plurality of heating bars 141 may be configured to include a third linear movement device 142 for collectively reciprocating and linearly moving in the vertical direction.

The plurality of heating bars 141 may be disposed to face the width direction of the current first surface 1a, and heated to a temperature for thermally bonding the first surface 1a and the second surface 1b to each other. can be In this case, the heating is achieved through the supply of electricity.

At this time, the reason that a plurality of heating bars 141 are provided is that, when thermal bonding is performed at a high temperature by forming a single number of heating bars 141, other portions adjacent to the thermal bonding portion of the first surface 1a are This is because it may be melted or deformed by heat.

Therefore, in the second thermal bonding progress unit 140, based on the longitudinal direction of the first surface 1a, starting from the first heating bar 141, the heating temperature can be set to gradually increase toward the last heating bar 141. have.

That is, after the fine thermal bonding is performed by the first heating bar 141, the first surface 1a and the second surface 1b are continuously processed, so that the second heating bar 141 is additionally thermally bonded to the same position. will do At this time, the temperature of the second heating bar 141 is set higher than that of the first heating bar 141 . As this process is repeated until the last heating bar 141, the first surface 1a and the second surface 1b that have passed through the last heating bar 141 have strong thermal bonding without deformation due to high temperature. it will be completed

The plurality of heating bars 141 are reciprocally linearly moved in the vertical direction by the third linear movement device 142. At this time, the third linear movement device 142 is the first surface 1a and the second surface 1b. The plurality of heating bars 141 are constantly moved in a straight line through pneumatic in accordance with the moving speed (advance speed) of the . For example, after pressing the plurality of heating bars 141 using pneumatic pressure in the downward direction, the pressure is momentarily removed, and at this time, a plurality of elastic bodies connected between the heating bar 141 and the third linear movement device 142 . Due to the elastic force of the (spring), the heating bar 121 is returned to the upper direction again. Accordingly, the third linear movement device 142 repeatedly performs the above process in accordance with the movement speed (advance speed) of the first surface 1a and the second surface 1b.

The second cooling proceeding unit 150 is located at the rear end of the second thermal bonding proceeding unit 140 , and thermal bonding formed on the first surface 1a in the same manner as the first cooling proceeding unit 130 described above. It serves to cool the area. In this case, the thermal bonding site may mean a site formed in the width direction of the first surface 1a. Meanwhile, in the case of the second cooling progress unit 150 , the detailed description will be omitted because cooling proceeds in the same manner as the first cooling progress unit 130 .

The additional processing proceeding unit 160 performs punching processing on the first surface 1a and the second surface 1b that pass through the second cooling proceeding unit 150 . More specifically, referring to FIG. 7 , the additional processing progress unit 160 performs punching processing at regular intervals in accordance with the moving speed (advance speed) of the first surface 1a and the second surface 1b. Here, the shape of the punched hole to be punched may be variously applied.

Meanwhile, in an embodiment, the punching process may be omitted depending on the type of the pouch-type package. For example, when the pouch-type package is a mask wrapper, the additional processing progress unit 160 may perform punching processing on the first side 1a and the second side 1b, and if punching processing is not required, additional processing proceeding unit 160 The processing progress unit 160 may omit the punching process for the film 1 .
