The first raw fabric 101 is preferably a flat synthetic resin and a composite fabric or an aluminum synthetic fabric. The second raw fabric 102 is preferably a flat liner fabric and a cylindrical fabric can be used. When the cylindrical second end 102 is used, the cylindrical forming process of the second end 102 in the sealing and bending portion 150 and the bonding process of the connecting portion are omitted.

In addition, the second fabric 102 may be a flat-type vinyl fabric having a function of blocking oxygen or a flat-type vinyl fabric having no oxygen-blocking function, and may be a cylindrical vinyl fabric having oxygen- It is possible to selectively use a cylindrical vinyl fabric having no blocking function.

2, the sealing and bending part 150 includes a first sealing and bending part 150-1 in which the sealing and bending shape of the second raw material 102 is progressed, And a second sealing and bending portion 150-2 in which the sealing and bending shape of the sealing and bending portion 101 is progressed. The first sealing and bending portion 150-1 and the second sealing and bending portion 150-2 And a second sealing and bending part 150 (150) connected to the adhesive member supply part 151. The second sealing and bending part 150 (150) is provided with an adhesive member supply part 151 for supplying an adhesive member to the cylindrical connection part of the first fabric 101, An adhesive member moving portion 152 is formed which moves the adhesive member toward the connection portion of the cylindrical vinyl fabric inner portion. The first and second sealing portions 150-1 and 150-2 are provided with a plurality of silicone rollers 150 for easy movement of the first and second fabrics 101 and 102, And a side fin 157 and a side guide roller for forming the first raw fabric 101 and the second raw fabric 102 in a cylindrical shape are formed respectively. Also, a cylindrical fabric formed by using the presser plate 156 connected to the end of the pressing portion 158 presses the connecting portion.

A bonding extruder for injecting a synthetic resin for bonding may be used as the adhesive member supply portion 151, and an adhesive film supply roll for supplying an adhesive film may be used.

When using a welding extruder, the extruder injection nozzle is connected to the welding extruder to serve as an adhesive member diaphragm 152, and the adhesive synthetic resin is injected through the extruder injection nozzle to the cylindrical connecting portion of the first fabric 101, The synthetic resin flows into the cylindrical connecting portion of the first raw fabric 101 as well as the cylindrical connecting portion of the second raw fabric 102 on the inner side so that the first raw fabric 101 and the second raw fabric 102 can be integrally bonded.

When using the adhesive film supply roll, the adhesive film supply roll serves as the adhesive member supply portion 151 and the adhesive film provided in the adhesive film supply roll is moved through the movement path of the adhesive member moving portion 152, And serves as the adhesive member diaphragm 152.

3 and 4, FIG. 3 shows the shape of the presser plate 156 used when the welding extruder is mounted on the adhesive member supply unit 151, and FIG. 4 shows a state in which the adhesive film supply roll 151 And the shape of the pressure plate 156 used when used.

A lower groove 156-2 is formed in a lower portion of the pressing plate 156 in the pressing plate 156 when the welding extruder is used and a lower groove 156-2 formed in the lower groove 156-2, Is introduced into the connecting portion of the cylindrical vinyl fabric through the extruder injection nozzle, and the bonding of the cylindrical vinyl fabric is progressed. The pressing plate 156 is provided with a contact surface 156-3 formed on both sides of the lower groove 156-2 due to the formation of the lower groove 156-2 formed on the bottom surface and contacting the cylindrical vinyl fabric, A circular hole 156-1 is formed.

A contact surface 156-3 for pressing the adhesive film supplied as a circular vinyl fabric and a circular hole 156-1 formed in the longitudinal direction are formed on the bottom surface of the pressure plate 156 when the adhesive film supply roll is used, Since the adhesive film is used, the lower groove 156-2 need not be formed as in the case of using the welding extruder.

Referring to FIG. 5, in the embodiment of the present invention, a pressure plate (not shown) connected to the end of the pressing portion 158 formed in the first sealing and bending portion 150-1 and the second sealing and bending portion 150-2 156 are formed by six pressing plates 156. Heat lines 201 are connected to the front three pressing plates 156 of the six pressing plates 156 so that the first fabric 101 and the second The cooling hose 211 is connected to the three pushing plates 156 at the rear to serve as a heat source 156a for applying heat to the cylindrical connecting portion of the fabric 102, And a cooling plate 156b serving to cool the cylindrical connecting portion of the first raw material 101 and the second raw material 102. [ The shapes of the heat plate 156a and the cooling plate 156b are the same, but their functions are different according to the apparatus connected to the circular hole 156-1. That is, when the heating wire 201 connected to the heat supply part 200 is connected to the circular hole 156-1 of the pressure plate 156, heat is transmitted to the pressure plate 156 through the connected heating wire 201, When the cooling hose 211 connected to the water-cooling supply unit 210 is connected to the circular hole 156-1 of the pressure plate 156, the pressure plate 156 is cooled through the cooling hose 211 Therefore, it functions as the cooling plate 156b.

The first connecting portion 158-1 and the second connecting portion 158-1 are connected to the pressing plate 156 in order to effectively press the connecting portion of the cylindrical vinyl fabric through the pressing plate 156 functioning as the heating plate 156a or the cooling plate 156b 158-2 are preferably made of elastic cushion springs, and the number of the heat plate 156a or the cooling plate 156b can be changed as needed.

Since the connecting portions of the first raw fabric 101 and the second raw fabric 102 formed in a cylindrical shape are thermocompression-bonded through heat transferred to the bonding synthetic resin or adhesive film and the heat plate 156a, the adhesive force is further increased, After passing through the cooling plate 156b located behind the heat plate 156a and cooling the adhered portion, the adhesive synthetic resin or the adhesive film is solidified and the adhesion progresses completely.

6, a plurality of bending rollers 155 and a pair of guide members 154 for receiving a part of the bending roller 155 inside are used to form M-shaped And the cylindrical vinyl fabric moves using the silicone rollers 153 mounted between the pair of guide members 154. [ A spring for buffering action is provided on the bending roller 155. The guide member 154 may be adjusted and replaced according to the size of the M-shaped bent portion to be formed. The silicone roller 153 is preferably made of a material that is not affected by heat transmitted from the heat plate 156a.

Referring to FIG. 7, a multi-layer composite cylindrical vinyl fabric having passed through the second pushing roll 160 is introduced into the tension device portion 170, and the introduced multi-layer composite cylindrical vinyl fabric is wound around the tension device portion 170, To a sealing and cutting portion 180 comprising a sealing portion 181 for thermally pressing one side of the cylindrical vinyl fabric of the multi-layer composite and a cutting portion 182 for cutting in a unit length. The upper roller 171 and the lower roller 172 can be moved up and down though three upper rollers 171 and three lower rollers 172 are formed in the tension device unit 170. In the second pressing roll 160, the cylindrical vinyl fabric of the multi-layer composite is continuously flowed, but in the sealing and cutting portion 180, the cylindrical vinyl fabric of the multi-layer composite is temporarily stopped during the sealing and cutting. That is, even when the movement of the cylindrical vinyl fabric of the multilayer composite is temporarily stopped in the sealing and cutting portion 180, since the cylindrical vinyl fabric of the multilayer composite is continuously introduced into the tension device portion 170 in the second push roll 160, The composite cylindrical vinyl fabric is loosened, whereby the multi-layer composite cylindrical vinyl fabric can be folded or wrinkled, and the unit length of the multi-layer composite vinyl bag is not constant. Therefore, a tension device unit 170 is installed to prevent this. The lower roller 172 of the tension device portion 170 moves downward when the movement of the cylindrical vinyl fabric of the multi-layer composite is stopped at the sealing and cutting portion 180 and the lower roller 172 of the multi- The lower roller 172 is moved upward again when the cylindrical vinyl fabric of the multi-layered composite is again moved in the sealing and cutting portion 180, and the inner surface of the tension unit 170 To control the length variation of the multi-layered composite cylindrical vinyl fabric. The process of moving the lower roller 172 up and down continues in succession.

The multi-layer composite cylindrical vinyl fabric having passed through the tension device portion 170 moves to the sealing and cutting portion 180. In the sealing and cutting portion 180, both sealing and cutting may be performed as required, or only sealing may be performed. In order to manufacture a multi-layer composite vinyl bag 300 cut to a unit length, the cutting of the vinyl fabric of a multi-layer composite using a cutting portion 182 is progressed to a unit length, The sealing work is progressed and discharged out of the apparatus. However, in order to manufacture the multi-layer composite vinyl bag 400 wrapped around the automatic wrapping roll, the vinyl fabric of the multi-layer composite is sealed at a predetermined interval by using the sealing portion 181, And is wound around the automatic wrapping roll by being fastened to the third winder 190, thereby completing the multi-layer composite bag 400. A multi-layer composite vinyl bag 400 wound on an automatic wrapping roll is for use in an automatic packaging machine.

A method of producing a multi-layer composite vinyl bag according to an embodiment of the present invention is as follows.
