Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2, the film fast cutting apparatus 100 according to the present embodiment includes a film supply unit 110, a film supply roller 120, a cutting roller 130, a previous roller 140, 150 and a cutting film storage unit 160.

As shown in FIG. 2, the film supply unit 110 is a component in which a film to be cut is wound in a roll shape and continuously supplies the film.

2, the film supply roller 120 is rotated by a film F supplied from the film supply unit 110 while being adsorbed on the outer circumferential surface thereof, to be. That is, the film supply roller 120 is installed adjacent to the cutting roller 130 to be described later. The film supply roller 120 rotates with its own power, while the film F is attracted to the outer circumferential surface thereof, To the roller (140).

Therefore, the film supply roller 120 is configured to include the adsorption roller 122 and the differential adsorption force providing means 124, as shown in FIG. As shown in FIG. 3, the adsorption roller 122 has a tube shape and is a component that rotates while winding the film F in an adsorbed state on the outer circumferential surface. The differential adsorption force providing means 124 is provided inside the adsorption roller 122 and is provided with a high adsorption portion 121 for providing a high first vacuum adsorption force to a portion of the adsorption roller 122, And a low adsorption unit 123 for providing a low second vacuum adsorption force.

3, the adsorption roller 122 rotating on the outside of the differential adsorption force providing means 124 repeatedly passes through the high adsorption force section S1 having a high adsorption force and the low adsorption force section S2 do. In the high attraction force period S1, the film F is prevented from moving before and after the film F is cut, and the low attraction force period S2 is formed by the film F 'cut by the previous roller 140, To be transferred. That is, the low attraction force section S2 has an attraction force smaller than the attraction force of the previous roller 140 so that the cut film F 'is transferred to the previous roller 140 in a state of being in contact with the previous roller 140 will be.

At this time, the differential adsorption force providing means 124, as shown in FIG. 3, makes the adsorption force differential providing section width equal to the length of the film F 'cut by the cutting roller 130, It is possible to easily transfer the film F 'to the previous roller 140, which is preferable.

2, the cutting roller 130 is disposed to be in contact with one side of the outer circumferential surface of the film supply roller 120, and the film F wound on the film supply roller 120 is fixed to a predetermined Length component. That is, the cutting roller 130 continuously cuts the film F provided by the film supply roller 120 while rotating itself.

For this, the cutting roller 130 includes a center roller 132 and a cutting blade 134, as shown in FIG. First, the center roller 132 is a roller having a cylindrical shape, and preferably has a smaller diameter than the film supply roller 120. Of course, the center roller 132 is provided with rotational power means (not shown) for rotating it.

As shown in FIG. 4, the cutting blade 134 is provided on the outer circumferential surface of the center roller 132 at a predetermined interval, and the film F wound on the film- Is a constituent element for pressing and cutting. At this time, the interval between the cutter blades 134 is set to be the same as the length of the film F to be cut, and the cutter blade 134 is positioned at a position close to the film supply roller 120, The installation angle is set to be precisely set so as to be orthogonal to the direction.

2, the pre-rollers 140 are provided so as to be in contact with the other side of the outer circumferential surface of the film supply roller 120, and are separated from the film supply roller 120 in a state of being cut by the cutting roller 130 120 to the cutting film F '. That is, the previous roller 140 moves the low adsorption section S2 while the film F 'cut by the cutting roller 130 is being adsorbed on the outer circumferential surface of the film supply roller 120 (F ') with high adsorption force at the moment when the film (F') is cut.

5, the transfer roller 140 has a diameter twice as large as that of the film supply roller 120, and a plurality of separation grooves 144 are formed along the circumferential surface of the transfer roller 140 It is desirable. When the diameter of the previous roller 140 is larger than the film supply roller 120, the film F 'transferred to the previous roller 140 is transferred to a state in which they are spaced apart from each other as shown in FIG. 6A . Keeping the cut films F 'separated from the outer circumferential surface of the previous roller 140 means that the film F' is separated from the previous roller 140 by the separation means 150 The means ensures the inward return time.

The separation grooves 144 are spaced apart from each other by a predetermined depth along the circumferential surface of the previous roller 140. 6A and 6B, the separation groove 144 provides a space for the separating means 150 to be driven up and down.

As shown in FIG. 5, a part of the transfer rollers 140 where the separation grooves 144 are not formed is provided with a film adsorption part 142 capable of adsorbing the cut film F '. The film adsorption unit 142 adsorbs the film with a larger attraction force than the low adsorption unit 123 of the film supply roller 120 described above.

2, the separating means 150 separates the cut film F 'transferred from the outer circumferential surface of the previous roller 140 from the previous roller 140, Element. That is, the separating means 150 separates and stores the cut film F 'transferred in a state of being spaced apart from the previous roller 140 in order to the cut film storage unit 160 to be described later.

5, the separating means 150 includes a separating fork 152 and a fork pivoting means 154, as shown in FIG. First, the separation fork 152 is installed in a shape and size that can be inserted into the plurality of separation grooves 144, and the cut film F 'adsorbed on the previous roller 140 is slid downward and separated Lt; / RTI >

5, the fork pivoting unit 154 is coupled to the ends of the plurality of separation forks 152 and rotates the separation forks 152 in the up-and-down direction. That is, as shown in FIG. 7, the fork pivoting means 154 rotates the separation fork, which is in a state of being inserted into the separation groove 144, at the moment when the cutting film F ' 6B, the cut film F 'is freely dropped by the separation fork 152 and housed in the cut film storage part 160 provided at the lower side.

While the cutter film is not present on the previous roller 140, the separation fork 152 is lifted again to return to the standby state inserted in the separation groove 144, and then the new cut film F ' The separating operation is repeated.

2, the cutting film storage unit 160 is disposed below the previous roller 140 and accommodates a film F 'separated by the separation unit 150 Element. The cut film storage unit 160 has a size and a structure capable of resting the cut film F ', and can be changed into various forms.
