Cloth clamping chuck and cloth handling apparatus

Abstract

A cloth clamping chuck and a cloth handling apparatus that can handle cloth so as to reduce falling of the cloth while avoiding damage to the cloth includes a pair of clamps, disposed facing each other, and an opening-closing means that moves the pair of clamps, relatively closer to or separated from each other. Each of the clamps has, at a leading end, a projecting part that projects toward the other opposite clamp. Each of surfaces of the projecting parts on a base end side of the clamps is formed either as a flat surface parallel to a facing direction of the pair of clamps or as an inclined surface inclining toward the above base end side while extending toward the other opposite projecting part.

1 . A cloth clamping chuck comprising a pair of clamps disposed facing each other, and an opening-closing means that moves the pair of clamps relatively closer to or separated from each other, wherein:
 each of the clamps has, at a leading end, a projecting part that projects toward the other opposite clamp; and   a surface of the projecting part on a base end side of the clamp is formed either as a flat surface parallel to a facing direction of the pair of clamps or as an inclined surface inclining toward the base end side while extending toward the other opposite projecting part.   
     
     
         2 . The cloth clamping chuck according to  claim 1 , wherein a gap is formed between the projecting parts facing each other in a fully closed position of the pair of clamps. 
     
     
         3 . The cloth clamping chuck according to  claim 2 , wherein the gap is set to be substantially equal to a thickness of two pieces of cloth to be clamped. 
     
     
         4 . The cloth clamping chuck according to  claim 1 , wherein at least one of the pair of clamps is provided so as to be able to swing around a swinging axis extending in a direction orthogonal to both an extension direction that is a direction from the base end toward the leading end of the clamp and the facing direction. 
     
     
         5 . A cloth handling apparatus comprising the cloth clamping chuck according to  claim 1  and a moving means that moves the cloth clamping chuck. 
     
     
         6 . The cloth clamping chuck according to  claim 2 , wherein at least one of the pair of clamps is provided so as to be able to swing around a swinging axis extending in a direction orthogonal to both an extension direction that is a direction from the base end toward the leading end of the clamp and the facing direction. 
     
     
         7 . The cloth clamping chuck according to  claim 3 , wherein at least one of the pair of clamps is provided so as to be able to swing around a swinging axis extending in a direction orthogonal to both an extension direction that is a direction from the base end toward the leading end of the clamp and the facing direction. 
     
     
         8 . A cloth handling apparatus comprising the cloth clamping chuck according to  claim 2  and a moving means that moves the cloth clamping chuck.
