Forward and reverse roller type wafer sealing system

Abstract

A forward and reverse roller type wafer sealing system includes a wafer seal tape, a wafer seal transfer member, an inflow conveyor belt, a first pressure roller member, a second pressure roller member and an outflow conveyor belt. The wafer seal tape has a shape wound in a roll type, and has a plurality of wafer seals attached in series to one surface. The wafer seal transfer member includes a supply holding member on which the wafer seal tape is mounted, a removing pulley for removing the wafer seal as the wafer seal tape is transferred, and a recovery holding member for winding a base member from which the wafer seal is removed using the removing pulley as a separation point. The inflow conveyor belt rotates in a forward rotation direction to transfer the packaging object in order to attach the wafer seal for preventing unfolding to a plurality of accumulated packaging objects. The first pressure roller member is disposed at a rear end of the inlet conveyor belt. As a part of a removed wafer seal is attached to the edge of one surface of the packaging object and transferred, the first pressure roller member bends the rest of the wafer seal in a U-shape to pressurize the edge of the other surface of the object to be packaged. The second pressure roller member is disposed at a rear end of the conveying roller member. The second pressure roller member transfers the packaging object having the wafer seal attached to the edge of one side and the edge of the other side. The outflow conveyor belt is disposed at a rear end of the second pressure roller. The outflow conveyor belt rotates in the forward rotation direction to transport the packaging object with the wafer seal attached.

What is claimed is: 
     
         1 . A forward and reverse roller type wafer sealing system comprising:
 a wafer seal tape having a shape wound in a roll type, and having a plurality of wafer seals attached in series to one surface;   a wafer seal transfer member comprising a supply holding member on which the wafer seal tape is mounted, a removing pulley for removing the wafer seal as the wafer seal tape is transferred, and a recovery holding member for winding a base member from which the wafer seal is removed using the removing pulley as a separation point;   an inflow conveyor belt that rotates in a forward rotation direction to transfer a packaging object in order to attach the wafer seal for preventing unfolding to a plurality of accumulated packaging objects;   a first pressure roller member disposed at a rear end of the inflow conveyor belt, and as a part of the removed wafer seal is attached to the edge of one side of the packaging object and transported, the rest of the wafer seal is bent in a U-shape and transferred by pressing the edge of the other surface of the packaging object;   a second pressure roller member disposed at a rear end of the first pressure roller member and conveying a packaging object having a wafer seal attached to an edge of one side and an edge of the other side; and   an outflow conveyor belt disposed at a rear end of the second pressure roller member and rotates in a forward rotation direction to transport the packaging object to which the wafer seal is attached to the outside.   
     
     
         2 . The forward and reverse roller type wafer sealing system of  claim 1 , wherein the first pressure roller member comprises:
 a first roller disposed at a rear end of the inlet conveyor belt and moving downward as the packaging object enters to bend the wafer seal downward; and   a second roller disposed at a rear end of the inflow conveyor belt and driven in the reverse rotation direction to bend the rest of the removed wafer seal in a U-shape to press the edge of the other surface of the packaging object.   
     
     
         3 . The forward and reverse roller type wafer sealing system of  claim 1 , wherein the second pressure roller member comprises:
 a third roller disposed at a rear end of the first pressure roller member and driven in the forward rotation direction to transfer the packaging object to which the wafer seal is attached to the outflow conveyor belt; and   a fourth roller disposed on the third roller and rotates forward according to the progress of the packaging object in a non-driven manner.
