A plurality of individual transfer units 100 may be connected in a line.

The stack unit 200 is disposed in front of the individual transfer unit 100 in the transfer direction.

The mask is seated on the stack unit 200 by the force transferred through the individual transfer unit 100.

The individual transfer unit 100 includes a motor 110, a power transmission assembly 130 rotated by the motor 110, a conveyor 120 circulated by the power transmission assembly 130, and the It is disposed on the upper side of the conveyor 120, and includes a pressure roller 150 for pressing the transferred mask.

The individual transfer unit 100 includes a transfer frame 101 on which the motor 110 is installed.

The power transmission assembly 130 and the conveyor 120 are rotated by the driving force of the motor 110.

The power transmission assembly 130 is installed on the transfer frame 101.

The power transmission assembly 130 is disposed inside the conveyor 120, the first roller 131 and the second roller 132 disposed at the front and rear ends of the conveyor 120, and the conveyor 120 ) To transmit the driving force of the motor 110 to at least one of the first support roller 133 and the second support roller 134 and the first roller 131 or the second roller 132 It includes a power transmission gear.

The first roller 131, the second roller 132, the first support roller 133, and the second support roller 134 are installed on the transfer frame 101 and rotate in place.

The power transmission gear may be omitted, and the rotational force of the motor 110 may be directly provided to the first roller 131 or the second roller 132. In this embodiment, the number of rotations of the motor 110 may be reduced or increased through the power transmission gear, and the conveying speed of the conveyor 120 may be adjusted through this.

This embodiment further includes a tension roller 140 for maintaining tension on the conveyor 120, and the tension roller 140 is disposed inside the conveyor 120. The tension roller 140 presses the conveyor 120 downward in the gravitational direction to form a tight tension on the conveyor 120.

The tension roller 140 may be installed on the transfer frame 101 and may be moved vertically by its own weight. The tension roller 140 is disposed between the first support roller 133 and the second support roller 134 and is disposed lower than the first support roller 133 and the second support roller 134.

The conveyor 120 may be moved between the first support roller 133 and the tension roller 140, and may be moved between the tension roller 140 and the second support roller 134.

The diameters of the first support roller 133 and the second support roller 134 are smaller than the diameters of the first roller 131 and the second roller 132.

The rotation center of the tension roller 140 is disposed lower than the rotation center of the first roller 131 and the second roller 132.

Through this structure, the conveyor 120 is transported to the mask 1, the transfer unit 121 located above the first roller 131 and the second roller 132, and the transfer unit 121 It is connected, and includes a circulation unit 122 positioned below the first roller 131 and the second roller 132.

The transfer unit 121 located on the upper side may be exposed.

The mask 1 is transferred while seated on the upper side of the transfer unit 121.

The mask 1 is formed of a material such as a nonwoven fabric. Since the mask 1 is manufactured in the form of a thin sheet, it may be bent or wrinkled. That is, when one side of the mask 1 is supported, the side not supported may be bent.

When the mask 1 is wrinkled during transport, the stacking height may vary and may be positioned out of the correct position. In order to prevent this, a mask pressing structure for maintaining the mask 1 in a flatly unfolded state before the mask 1 is mounted on the stack unit 200 may be added.

In this embodiment, the mask pressing structure is operated by a mechanism for pressing the mask 1 from the upper side. The mask pressing structure presses the mask 1 from the upper side so that the moving end (staging unit side) of the mask 1 is slightly spaced upward.

Based on the mask 1 that is moved to the stack unit 200, an end on the side of the stabilizing unit 200 is defined as one end (2), and an end on the opposite side in the moving direction is defined as the other end (3).

The mask pressing structure may slightly raise the one end 2 upward from the transfer unit 121 by pressing the other end 3.

In this embodiment, a pressure roller 150 is used as the mask pressing structure. The pressure roller 150 is disposed on the upper side of the conveyor 120 and may press the upper side of the mask 1 during transfer.

The pressure roller 150 may be rotated in the transport direction of the mask 1. The rotation shaft 151 of the pressure roller 150 is orthogonal to the transport direction of the mask 1. In order to reduce friction, the rotation shaft 151 may be provided with a bearing.

In particular, the pressure roller 150 may be moved in the vertical direction. Depending on the thickness of the mask 1 to be manufactured, the pressure roller 150 may be moved in the vertical direction, and may be rotated about the rotation axis 151 even in the process of moving in the vertical direction.

In this embodiment, a separate driving force is not provided to the pressure roller 150. Unlike the present embodiment, it is possible to rotate at the same speed as the conveyor 120 by providing the rotational force.

The pressure roller 150 is rotatably installed on the transfer frame 101. The pressure roller 150 may be moved in the vertical direction along the transfer guide 155 formed on the transfer frame 101. The rotation shaft 151 may be rotated while spanning the lower end of the transfer guide 155.

When the thickness of the mask 1 is thick, the rotation shaft 151 may move the transfer guide 155 upward, and after the mask 1 passes, it may be returned downward by its own weight.

In this embodiment, the pressure roller 150 is disposed above the first roller 131. The rotation shaft 151 of the pressure roller 150 and the rotation shaft 131a of the first roller 131 are disposed on the same vertical line.

In this embodiment, the pressure roller 150 and the first roller 131 are formed to have the same diameter, and may be rotated at the same number of rotations by the movement of the conveyor 120.

Meanwhile, a plurality of the pressing rollers 150 may be disposed. A first pressure roller 150a is disposed on the side of the mask traveling direction in which the plurality of pressure rollers 150 are disposed, and a second pressure roller 150b is disposed on the opposite side.

The first pressing roller 150a and the second pressing roller 150b have the same configuration. The first pressing roller 150a and the second pressing roller 150b are disposed to be spaced apart in a mask moving direction. The first pressing roller 150a and the second pressing roller 150b form a separation distance D. The separation distance D may be a horizontal width or a vertical width of the mask 1.

In this embodiment, the separation distance (D) may be equal to the length between one end (2) and the other end (3), or may be formed smaller than the length between one end (2) and the other end (3). When the mask 1 is moved, the first pressing roller 150a and the second pressing roller 150b may simultaneously press the one end 2 and the other end 3 of the mask 1.

When the other end 3 of the mask 1 passes through the first pressure roller 150a, the one end 2 may be slightly spaced upward by the pressed other end 3. By slightly floating one end 2 upward, friction between the conveyor 120 and the mask 1 can be minimized.

In addition, as the one end 2 slightly rises, friction can be minimized when the mask 1 is thrown to the stack unit 200 by the conveying force of the conveyor 120.

1 to 5 masks 1 per second are continuously thrown to the stack unit 200 by the rotational speed of the conveyor 120.

If the one end 2 is not slightly raised, friction with the conveyor 120 increases, and thus it may not be thrown to a desired distance. In particular, when the mask 1 is continuously stacked above the mask 1 is disposed, if the one end 2 does not slightly rise, it may not be transferred to a desired position due to friction between the masks 1.

The pressure roller 150 may be continuously stacked at an accurate position (stack unit) by reducing friction of the mask 1 transferred in a continuous process.

Although it will be described later, the mask 1 may be thrown in the conveying direction while passing through the pressure roller 150 to be continuously stacked under the moving direction.
