Machine tool
A machine tool equipped with a robot includes a stocker which has one or more effector holder units for holding an end effector to be mounted on the robot, in which the stocker can be stored within a casing of the machine tool. At least a part of the stocker is configured to be bilaterally advanceable into a machining chamber of the machine tool and an external region located outside the machine tool.
1. A machine tool comprising:
a spindle protruding from a first wall face of a machining chamber,
an articulated arm robot protruding from the first wall face,
a stocker including at least two effector holder units, each of the at least two effector holder units configured for holding a respective end effector so that at least one end effector of the end effectors is to be mounted on the robot,
a first slide mechanism which retains the stocker in a state in which the stocker is slidable between a stored location where an entirety of the stocker is stored within a casing of the machine tool and an external region which is external to the casing of the machine tool, and
a second slide mechanism which together with the first slide mechanism retains the stocker in a state in which the stocker is slidable between the stored location and the machining chamber of the machine tool, the second slide mechanism comprising a guide rail on which the stocker is slidable,
wherein when the stocker is at the stored location: an entirety of the guide rail is stored in the casing,
the stocker is disposed adjacent to the first wall face and within the casing of the machine tool, and
a shutter is fixed to an end of the second slide mechanism that is adjacent to the machining chamber, the shutter forming an inner wall of the machining chamber and being continuous with the first wall face.
2. The machine tool according to claim 1 , wherein at least a part of the stocker is advanceable from the casing of the machine tool into the machining chamber of the machine tool and advanceable from the casing of the machine tool to the external region which is external to the casing of the machine tool.
3. The machine tool according to claim 1 ,
wherein the first slide mechanism comprises:
a block base that is slidable along the guide rail; and
a guide shaft that is slidable relative to the block base and coupled to the stocker.
4. The machine tool according to claim 1 , further comprising:
a handle disposed on the first slide mechanism in the stored location and non-exposed by the casing when the stocker is at the stored location, and slid external to the casing when the stocker is moved external to the casing.
