The present invention also relates to a cutting by-product removing apparatus for a roll film cutting system that can remove the generated cutting by-products by inhalation.

  This application claims priority based on Korean Patent Application No. 10-2010-0055993 filed on June 14, 2010 and Korean Patent Application No. 10-2011-0045793 filed on May 16, 2011. All the contents disclosed in the specification and drawings of the application are incorporated in the present application.

  In general, a liquid crystal display device essentially includes a liquid crystal panel composed of a pair of transparent insulating substrates, which are opposed to each other with a liquid crystal layer interposed therebetween, and on which an electric field generating electrode is formed. The molecular orientation is artificially adjusted, and various images are displayed using the light transmittance that changes in this process.

  Polarizing films for visualizing changes in the liquid crystal alignment of the liquid crystal display device are disposed on the upper and lower surfaces of the liquid crystal panel. The polarizing film transmits light having a polarization component that matches the transmission side. The liquid crystal display device determines the degree of light transmission according to the arrangement of transmission axes of polarizing films arranged on the upper and lower surfaces of the liquid crystal panel and the alignment characteristics of the liquid crystal.

  A roll-shaped polarizing film manufactured by various methods known in the industry (hereinafter referred to as “polarizing film roll”) is a size of a liquid crystal display device corresponding to a mechanical cutter (for example, a cutting press or a super cutter). It should be cut (cut) every time.

  However, when the polarizing film roll is cut with a mechanical cutter such as a cutting press or a super cutter, the cut surface has to undergo a chamfering process, and a large amount of dust is generated in the cutting process of the polarizing film roll. Additional process costs and environmental processing costs are incurred. This leads to an increase in production cost and a decrease in productivity. In order to improve this, recently, an apparatus for cutting a polarizing film roll using a laser has been developed. When the polarizing film roll is cut with a laser processing machine, cutting by-products generated from the power of the laser are sucked and removed by a suction unit.

The discharge part 146 includes four discharge pipes provided on the side surface of the suction body 144. Each discharge pipe of each discharge unit 146 can be connected to a dust collection unit (not shown). The suction body 144 communicating with the suction portion 142 is fixed to the suction bracket 148, and the suction bracket 148 is fixed to an operating rod 152 of a reciprocating member 150 described later.

  The reciprocating member 150 includes an actuator 154 including an operating rod 152 connected to the suction member 130 and a guide bar 156 capable of guiding the reciprocating movement of the suction member 130.

  The operation of the cutting byproduct removing apparatus of the roll film cutting system according to the preferred embodiment of the present invention constructed as above will be described.

  7 and 8 are block diagrams for explaining the operation of the cutting byproduct removal apparatus according to a preferred exemplary embodiment of the present invention.

  First, as shown in FIG. 7, when the polarizing film roll F is transferred to the inside of the main frame 116 over the suction plates 134 and 136 of the suction member 130 by a transfer means (conveyor) (not shown), the suction member 140 is moved. The suction portion 142 is lowered between the gaps (C) of the suction member 130 by the actuator 154 of the reciprocating member 150. This is because when the polarizing film roll F is inserted or when the cut polarizing film roll F advances forward (right side in FIG. 7), the suction film 140 attracts the end of the polarizing film roll F to the right suction plate. This is to prevent it from being applied to 136 (suction pad 135). Therefore, the end of the polarizing film roll F advances smoothly without being applied to the right suction plates 134 and 136.

  Next, when the transfer of the polarizing film roll F to the predetermined position (cutting position) is completed, the operation of the transfer means (conveyor) is stopped by sensing a sensor (not shown) and controlling the control unit. Then, as shown in FIG. 8, the actuator 154 of the reciprocating member 150 raises the suction member 140 so that the end of the suction portion 142 is close to the lower surface of the polarizing film roll F.

  Then, the control unit operates the suction member 130 to fix the position of the polarizing film roll F through the vacuum suction hole 132. At the same time, the control unit operates the suction member 140 to prepare for inhaling a by-product cut by the laser head 125 through the suction unit 142.

  Next, the laser head 125 cuts the polarizing film roll F in the width direction while moving in the width direction of the polarizing film roll F. In this process, the generated cutting by-product is sucked through the suction portion 142 of the suction member 140 located between the suction plates 134 and 136 of the suction member 130 and discharged through the suction body 144 and the discharge portion 146.

  Meanwhile, the first dust collecting member 160 collects and removes by-products that are scattered to the upper part of the polarizing film roll F while the polarizing film roll F is cut by the laser head 125, and the second dust collecting member 170 The cutting by-product that falls without being sucked through the suction member 140 and the first dust collecting member 160 is collected and removed.

  Accordingly, the cutting byproduct removal apparatus 100 according to a preferred exemplary embodiment of the present invention continuously inhales and removes the cutting byproduct generated when the polarizing film roll F is laser cut, thereby removing the polarizing film roll F itself and the laser. Contamination and damage of the cutter 50 can be prevented and the transfer of the polarizing film roll F can be facilitated.

  Although the roll film cutting system according to the preferred embodiment of the present invention has been described by taking a polarizing film roll as an example, those skilled in the art will appreciate that such a roll film can also be applied to a patterned retarder film roll for a stereoscopic display device. You can understand well.
