Tool storage device and tool reversing device

Abstract

A tool storage device includes: a first stocker on which a plurality of tools used for bending processing are mountable in a first direction; and at least one second stocker on which the plurality of tools are mountable in the first direction, the at least one second stocker being arranged side by side with the first stocker in a second direction orthogonal to the first direction, in which the second stocker is configured to be movable in a third direction orthogonal to each of the first direction and the second direction. The tool reversing device includes a tool mounting part on which a tool used for bending processing is mountable; a rotating mechanism configured to rotate the tool mounting part in a direction perpendicular to a mounting direction of the tool, in which the tool mounting part includes a mounting part body formed into a U-shaped cross section so as to constitute a pair of wall parts and a bottom part, the mounting part body being configured to allow insertion of a shank part of the tool, an locking groove provided on at least one inner wall surface of the pair of wall parts so as to be engageable with a protrusion extending in the perpendicular direction and protruding from a surface of the shank part, and a plurality of locking strips provided at prescribed positions in the locking groove and configured to engage with the protrusion from the perpendicular direction.

1 . A tool storage device, comprising:
 a first stocker on which a plurality of tools used for bending processing are mountable in a first direction; and   at least one second stocker on which the plurality of tools are mountable in the first direction, the at least one second stocker being arranged side by side with the first stocker in a second direction orthogonal to the first direction, wherein   the second stocker is configured to be movable in a third direction orthogonal to each of the first direction and the second direction.   
     
     
         2 . The tool storage device according to  claim 1 , wherein
 the first stocker and the second stocker each include a plurality of stages in the third direction.   
     
     
         3 . The tool storage device according to  claim 1 , wherein
 the first stocker and the second stocker are provided in order of the first stocker configured in a fixed state and the second stocker configured to be movable, from a side far from a tool changing robot, the tool changing robot being arranged on one side of the tool storage device in the second direction.   
     
     
         4 . The tool storage device according to  claim 3 , wherein
 the second stocker moves so as to retract to a non-movable area of an arm part of the tool changing robot, when the tool changing robot performs tool change in the first stocker.   
     
     
         5 . The tool storage device according to  claim 4 , wherein
 the second stocker moves to a position not overlapping the first stocker in the second direction with reference to a fixed position of the first stocker.   
     
     
         6 . A tool reversing device, comprising:
 a tool mounting part on which a tool used for bending processing is mountable; and   a rotating mechanism configured to rotate the tool mounting part in a direction perpendicular to a mounting direction of the tool, wherein   the tool mounting part includes   a mounting part body formed into a U-shaped cross section so as to constitute a pair of wall parts and a bottom part, the mounting part body being configured to allow insertion of a shank part of the tool,   a locking groove provided on at least one inner wall surface of the pair of wall parts so as to be engageable with a protrusion extending in the perpendicular direction and protruding from a surface of the shank part, and   a plurality of locking strips provided at prescribed positions in the engagement groove and configured to engage with the protrusion from the perpendicular direction.   
     
     
         7 . The tool reversing device according to  claim 6 , wherein
 the mounting part body further includes friction application means provided on a surface of the bottom part.   
     
     
         8 . The tool reversing device according to  claim 6 , wherein
 each of the plurality of locking strips has a surface facing a center of the locking groove in the perpendicular direction, the surface constituting a tapered surface gradually expanding from the center toward the other wall part, out of the pair of wall parts, in a range from a groove bottom part to a groove open part.   
     
     
         9 . The tool reversing device according to  claim 8 , wherein
 the plurality of locking strips are provided in a vicinity of the center of the locking groove in the perpendicular direction.   
     
     
         10 . The tool reversing device according to  claim 9 , wherein
 the plurality of locking strips are provided in a vicinity of an end portion of the locking groove in the perpendicular direction.
