Tape feeder and carrier tape feeding method using same

Abstract

To provide a tape feeder capable of reducing absorption dislocation, a tape feeder according to the present invention is a feeder feeding a carrier tape including a plurality of component storage units of a rectangular shape provided at predetermined intervals in a feed direction. The tape feeder includes a first magnet which is provided below a bottom surface of the component storage unit fed to a feed region so as to extend in the feed direction below one side of the bottom surface of the component storage unit in a width direction, and which attracts a component of the component storage unit fed to the feed region to one side of the bottom surface of the component storage unit in the width direction.

         4 . The tape feeder according to  claim 3 ,
 wherein said first magnet and said second magnet are integrated together to form an L-shaped magnet.   
     
     
         5 . The tape feeder according to  claim 1 ,
 wherein said first magnet is provided below half of the bottom surface.   
     
     
         6 . The tape feeder according to  claim 1 ,
 wherein said first magnet is formed of an elastic body.   
     
     
         7 . The tape feeder according to  claim 1 , further comprising
 an elastic member of a plate-like shape supporting the bottom surface of the component storage unit fed to the feed region,   wherein said first magnet is attached to a surface of said elastic member opposite to a side on which the bottom surface is placed.   
     
     
         8 . The tape feeder according to  claim 1 ,
 wherein said first magnet is provided below bottom surfaces of the plurality of said component storage units fed to the feed region.   
     
     
         9 . The tape feeder according to  claim 1 ,
 wherein a front end part of said first magnet in the feed direction is provided below a portion occupying one fourth of an area of the bottom surface.   
     
     
         10 . A carrier tape feeding method of feeding in a tape feeder a carrier tape including a plurality of component storage units of a rectangular shape provided at predetermined intervals in a feed direction,
 attracting, by a first magnet and a second magnet forming an L-shaped magnet, a component of the component storage unit fed to a feed region in the tape feeder to one side of a bottom surface of the component storage unit in a width direction and towards back in the feed direction,   wherein the first magnet is provided below the bottom surface of the component storage unit fed to the feed region so as to extend in the feed direction below one side of the bottom surface in the width direction, and attracts the component of the component storage unit fed to the feed region to one side in the width direction, and   the second magnet is provided at back in the feed direction with respect to the first magnet below the bottom surface of the component storage unit fed to the feed region, and attracts the component of the component storage unit fed to the feed region towards the back in the feed direction.   
     
     
         11 . The tape feeder according to  claim 1 ,
 wherein said first magnet and said second magnet are integrated together.   
     
     
         12 . A carrier tape feeding method of feeding in a tape feeder a carrier tape including a plurality of component storage units of a rectangular shape provided at predetermined intervals in a feed direction,
 attracting, by a first magnet and a second magnet forming an L-shaped magnet, a component of the component storage unit fed to a feed region towards one side of a bottom surface of the component storage unit in a width direction and towards back in the feed direction,   wherein the first magnet is provided below the bottom surface of the component storage unit fed to the feed region so as to extend in the feed direction below one side of the bottom surface in the width direction, and attracts the component of the component storage unit fed to the feed region to one side in the width direction,   the second magnet is provided at back in the feed direction with respect to the first magnet below the bottom surface of the component storage unit fed to the feed region, and attracts the component of the component storage unit fed to the feed region towards the back in the feed direction, and
