First, when defining a term for a direction, the front or rear may refer to the direction (X) from the right to the left (Y) or the opposite direction (Y), as shown in Figure 1, one side or the other direction is the paper tube fixing part In the hollow direction formed in the 110, it may mean a direction (Z) coming from the ground or the opposite direction (W).

1 and 2, the roll back manufacturing apparatus 10 including the automatic vinyl fabric automatic winding device 100 according to an embodiment of the present invention is a vinyl fabric automatic winding device 100, cut line forming apparatus 200 And an overload prevention device 300.

The cutting line forming device 200 and the overload prevention device 300 will be described later with reference to FIGS. 11 to 13, and the vinyl cloth automatic winding device 100 will be described first.

The vinyl fabric automatic winding device 100 is a pressurizing unit for pressing the vinyl fabric (V1) formed with the cut line to cut the paper tube fixing portion 110, the vinyl line formed with the cut line (V1) for fixing the paper pipe (1). 120 and a rotational force providing unit 130 to provide a rotational force for cutting along the cutting line.

Here, the branch pipe fixing unit 110, the pressing unit 120 and the rotational force providing unit 130 are all the main body portion 140 constituting the appearance of the automatic automatic fabrication device 100 vinyl according to an embodiment of the present invention. It may be fastened to the), the main body 140 may be configured to visually observe the configuration of the inside.

However, the main body 140 may be configured in a sealed structure to block the internal configuration from the outside to prevent the appearance of beauty and safety accidents.

The branch pipe fixing part 110 is a support structure that allows the vinyl fabric V1 having the cut line supplied to the inside of the main body part 140 to be wound around the branch pipe 1, so that the branch pipe 1 can be rotated at a predetermined position. I can support it.

Specifically, the branch pipe (1) may be a cylindrical structure having a hollow therein while having a width corresponding to the width of the vinyl fabric (V1).

Here, the branch pipe (1) can be supported at a predetermined position by inserting the steel rods of the branch pipe fixing part (110) into the hollow interior from both sides of the branch pipe (1), and rotates at high speed by the rotation of the steel bar Can be.

On the other hand, the width of the branch pipe fixing part 110 may be formed to be larger than the width of the branch pipe (1), due to which the branch pipe 1 is slightly biased toward one side or the other direction of the branch pipe fixing part (110) Can be fixed.

However, the position of the branch pipe 1 disposed in the branch pipe fixing unit 110 is not constantly determined, and may be variously changed to suit the intention of those skilled in the art.

Here, the rotational force for the rotation of the branch pipe 1 in the branch pipe fixing part 110 is a rotary roller 150 having a steel rod or vinyl fabric (V1) inserted between the hollow of the branch pipe (1). It may be provided by, there is no particular limitation on the driving means of the steel bar or the rotating roller 150.

 Therefore, the driving means may be a general driving motor, but may be applicable as long as it can provide a rotational force to the steel bar or the rotary roller 150.

On the other hand, the paper tube fixing part 110 may be movable to the front or rear, may be fastened to be movable to the body portion 140.

That is, the branch pipe fixing part 110 is stable in the rotation of the branch pipe (1) interlocked with the rotation of the rotary roller 150 is fixed to the front so that the vinyl fabric (V1) having a cut line formed in the branch pipe (1). It can be supported by, and when the winding of the branch pipe (1) is completed can be moved backward to produce one rollback (2).

That is, the branch pipe fixing part 110 may be disposed in front of the main body part 140 to wind the vinyl fabric V1 having the cut line to the branch pipe 1, and the roll is completed and rolled back 2. It may be disposed behind the main body 140 to produce a).

Thus, the paper tube fixing portion 110 may be moved forward and backward within the body portion 140, both of which may be automated by the controller.

On the other hand, the branch pipe fixing part 110 is disposed in front of the main body portion 140, when the winding of the vinyl fabric (V1) having a cut line formed in the branch pipe (1) is completed, as described above the main body portion ( Can be moved rearward within 140.

This is, after all, to produce a rollback (2) by cutting the vinyl fabric (V1) having a cut line, a specific manufacturing process will be described later with reference to Figures 3 to 10c.

When the paper tube fixing part 110 is completed to move backward in the body portion 140, the vinyl fabric (V1) having a cut line wound around the paper tube (1) may be disposed extending in front of the body portion 140. In addition, the automatic vinyl cloth winding apparatus 100 according to an embodiment of the present invention is prepared for cutting.

That is, the vinyl fabric automatic winding device 100 according to an embodiment of the present invention may cut the vinyl fabric V1 having a cut line by rotating the paper tube fixing part 110 at a predetermined angle. , The rotational force capable of rotating the branch fixing part 110 may be provided by the rotational force providing unit 130.

In other words, the rotational force providing unit 130 (see FIGS. 7A and 7B) rotates the branch pipe fixing unit 110 disposed at the rear of the main body 140 to apply an external force to the tear line formed in the vinyl fabric V1. It can be applied, thereby the vinyl fabric (V1) is to be cut along the cut line.

Specifically, the rotational force providing unit 130 may rotate the other side by a predetermined angle with one side of the branch fixing part 110 as a rotation axis, and if the vinyl fabric (V1) is cut along the perforated line by the rotation, the original state Can be returned to.

In this case, the rotation direction of the other side of the branch fixing part 110 may be directed toward the rear, and for this purpose, the rotation force providing unit 130 may be coupled to the other side of the branch fixing part 110.

That is, the rotational force providing unit 130 may have a variable length in the front and rear, and may be instantaneously increased for rotation toward the rear of the other side of the branch fixing part (110).

Therefore, as the length of the rotational force providing unit 130 is increased, the other side of the branch pipe fixing unit 110 coupled to the end of the rotational force providing unit 130 may be rotated to the rear, and thus, the vinyl fabric V1. Can be cut along the perforation line.

However, the direction of rotation of the branch pipe fixing unit 110 is not limited to the rear side, but may be forward or by combining the rotational force providing unit 130 to both one side and the other side of the branch pipe fixing unit 110. One side and the other side of the 110 may be cut by rotating in the opposite direction at the same time.

11 is a schematic view showing a vinyl bag manufacturing apparatus including a vinyl cloth automatic winding apparatus according to an embodiment of the present invention, Figure 12 is a schematic diagram showing a cut line forming apparatus provided in the vinyl bag manufacturing apparatus according to the present invention. It is an enlarged view, FIG. 13 is a schematic perspective view showing the overload prevention device provided in the vinyl bag manufacturing apparatus according to the present invention.

11 to 13, the vinyl bag manufacturing apparatus 10 according to the present invention is a vinyl fabric automatic winding device 100, a cut line forming device 200 and the overload prevention device described with reference to FIGS. 300).

Here, since the vinyl fabric automatic winding device 100 has been described with reference to FIGS. 1 to 10, it will be omitted below.

The cut line forming apparatus 200 is a structure for forming a cut line in the vinyl fabric V2 unwound from the vinyl fabric supply unit 400, and may include a sealing unit 210 and a cut unit 220.

Here, the sealing unit 110 may be sealed by heat-sealing the vinyl fabric (V2) unrolled from the vinyl fabric supply unit 400 in the upper and lower surfaces, the cut portion 220 is the sealing unit 210 It may be disposed adjacent to and to cut the sealed portion and the neighboring portion.

On the other hand, the sealing unit 210 and the cutout 220 may be integrally formed to form a first sealing cutout 230 to be lifted and lifted at the same time, the cutting line forming device 200 is the first sealing The second sealing cutout 240 may be disposed to be spaced apart from the first sealing cutout 230, similarly to the cutout 230.

Here, the separation distance between the first sealing cutout 230 and the second sealing cutout 240 may be fixedly variable, which may be variously changed according to the size of the rollback 2.

Therefore, the first sealing cutout 230 and the second sealing cutout 240 may be lifted in conjunction with each other, and the vinyl fabric V2 passing through the main body 250 by the repeated lifting movement is continuously. At the same time, it can seal automatically and form a cutting line.

The overload protection device 300 may be disposed between the cut line forming device 200 and the automatic vinyl cloth automatic winding device 100, and may include a plurality of rotating rods 310 and 320.

Therefore, the vinyl fabric V1 sealed by the cut line forming apparatus 200 and having the cut line may be supplied to the vinyl cloth automatic winding apparatus 100 while wrapping the plurality of rotating rods 310 and 320.

Here, the overload prevention device 300 may include a plurality of upper rotating rods 330 fixed to the main body 350 and a plurality of lower rotating rods 340 that can be lifted and lowered in the main body 350. Due to the lifting action of the plurality of lower rotating rods 340, it is possible to prevent the stagnation of the vinyl fabric V1 having a cut line.

In other words, when the vinyl fabric V1 having the perforated line is cut by the vinyl automatic winding device 100, the supply of the vinyl fabric V1 having the perforated line is temporarily stopped, but the perforated line is formed from the tear line forming apparatus 200. The supply of the formed vinyl fabric V1 is continued without stopping.

Therefore, the margin of the vinyl fabric V1 generated in the process of cutting the vinyl fabric V1 having the cut line by the vinyl fabric automatic winding device 100 needs to be temporarily stored. This can be solved by the prevention device 300.

That is, the amount of the vinyl fabric (V1) accommodated in the overload protection device 300 by the lowering of the plurality of lower rotating rods 340 may be increased, thereby continuing the process flow without stopping.

However, after the vinyl fabric V1 having the perforated line is cut by the vinyl cloth automatic winding device 100, the feed rate of the vinyl fabric V1 having the perforated line to the vinyl cloth automatic winding device 100 may be formed. The feed rate from the device 200 to the overload protection device 300 may be greater than the amount of the vinyl fabric V1 accommodated in the overload protection device 300.

That is, as the plurality of lower rotating rods 340 are raised and lowered repeatedly, the overall rotating stability can be realized.

In the above description of the configuration and features of the present invention based on the embodiment according to the present invention, the present invention is not limited thereto, and various changes or modifications can be made within the spirit and scope of the present invention. It will be apparent to those skilled in the art that such changes or modifications fall within the scope of the appended claims.
