The fabrics 11a, 11b, 11c, and 11d pass through the inlet rollers 15a, 15b, and 15c in the fabric supply device 12, and the bag fabrics 11a and 11b are positioned at the upper and lower portions thereof. In this case, the cushion vinyl fabrics 11c and 11d are continuously passed through the structure. At this time, the fabric supply device 12 measures the tension of the fabrics 11a, 11b, 11c, and 11d that are released, stops when it is loose, and drives a motor (not shown) to release the fabric when it is tight. The main operation is to perform each operation to maintain the optimum tension.

The upper and lower fabrics 11a, 11b, 11c, and 11d are aligned neatly while passing through the inlet rollers 15a, 15b, and 15c which are introduced in this way. The fabrics 11a, 11b, 11c, and 11d in the aligned state are introduced into the distribution hole 21 of the tension adjusting device 20, and the pressure plate 22 installed therein is pressed at an appropriate pressure to maintain the aligned state. Keep it intact and let it in. Subsequently, the original fabrics 11a, 11b, 11c, and 11d are introduced into the through-holes 31 of the cushion vinyl joining device 30, and the original fabrics are divided into the upper envelope fabric 11a and The cushion vinyl fabric 11c, the lower bag fabric 11b, and the cushion vinyl fabric 11d are separately introduced and introduced into the bag fabric 11a, 11b by the heat of a heater installed in the upper and lower portions, and the cushion vinyl fabric 11c, 11d. ).

In addition, by installing the size adjusting device 60 in front of the cushion vinyl bonding device 30 to be able to stably maintain the fabric to be transported. This is a device that is required when manufacturing bags of different sizes, and the more precise bags can be manufactured by preventing the flow of the conveyed fabric in the transverse direction by transferring the axis according to the width of the fabric.

On the other hand, the sealing tape hanger 34 may be installed in the center of the fabric supply device 11, as shown in Figure 3 and attached while pulling the fabric into the inlet roller (15a) (15b) (15c). At this time, there is no need for a separate adhesive roller.

In addition, the bag manufacturing apparatus described above is to produce a bag in a single line, so for mass production it would be more efficient to produce a double row type, or two lines.

In the case of such a structure, the width of the fabric is doubled to be transferred, and the sealing tape hanger 34 installed at the next position of the fabric mounting portion or the cushion vinyl bonding device 30 is configured to be installed at both sides. This is because the inlet portion of the bag is formed on both sides.

In addition, the sealing device 40 is composed of a horizontal sealing blades 401, 401a and a vertical sealing blade 402, as shown in Figure 9b, without having to configure a separate sealing device in the sealing blade structure of Figure 9a Another horizontal sealing blade 401a is coupled to the sealing blade 401 so as to be possible.

In this case, as shown in FIG. 9B, the sealing unit may be cooled and cut by the cooling device 90 installed at the next position of the sealing device 40.

Figure 7 is another embodiment of the present invention can be folded to attach the top and bottom by folding one fabric without dividing the fabric into upper and lower.

In order to enable such a structure, a device capable of continuously folding a wide flat fabric is required.

Therefore, the inlet is flat between the cushion vinyl bonding device 30 and the sealing device 40 at the next position of the cushion vinyl bonding device 30, and the center part is gradually folded so that the exit forms an acute angle so that the fabric passing therethrough is half. The fabric folded portion 80 is provided to be folded.

The fabric folded portion 80 is attached to one fabric vinyl on one surface of the fabric is attached to the inlet is gradually folded when discharged to the outlet is discharged in a fully folded state. Since the discharged fabric is introduced into the sealing device 40, since the portion forming the lower end of the bag is folded and sealed, only the portion forming the side surface as shown in FIG. 8 needs to be cut. Before cutting, it is cooled by a cooling device 90 as shown in FIG. 9C and then cut. In particular, since the sealing blade of the sealing device 40 only needs to seal the side surface of the bag, it is only necessary to configure the horizontal sealing blade as shown in FIG. 9C.

As described above, the present invention sets the fabric in the fabric feeder, and then the fabric passes through the inlet roller, the tension adjusting device, the cushion vinyl bonding device, the tape attachment roller, the sealing device, and the transfer roller. By passing through the automatic production of the safety bag, it is possible to realize the standardization of the product, and to minimize the defects of the product and increase the productivity of the product. In addition, the device of the present invention has the advantage that it is possible to manufacture bags of various specifications with a single device.
