Machine tool with optimally positioned operator station
View Patent ↗An operator station is positioned on the outside of a machine tool on the same side of the machine as the tool magazine and the automatic tool changer, to improve the ergonomics of the machine by keeping the tool loading access as close as possible to the operator. This location also allows easy visual access to the tools in the magazine and in the ready position in the tool changer. An angled “tunnel” window passing across the front of the tool magazine and the Y-axis column allows direct visual observation of the working zone of the machine tool from the operator station. A door on the side of the machine allows access from the operator station to a utilities panel located just inside of the door permitting ready operator access to switches, valves, fill points, filters and gages that are located on the panel.
1. A machine tool having generally perpendicular X, Y, and Z axes of movement, and the machine tool having a working zone containing a working tool, the machine tool comprising:
a Y-axis column;
a tool magazine mounted on the side of the Y-axis column;
an automatic tool changer for the tools in the tool magazine;
guarding surrounding the X, Y, and Z axes of the machine tool, the Y-axis column, the tool magazine and the automatic tool changer;
an operator station for the machine tool including a control panel for the machine tool and located on the outside of the guarding and positioned on the same side of the machine tool as the tool magazine and the automatic tool changer such that the tool magazine and tool changer are located between the operator station and the working zone, whereby an operator has visual access to the tool magazine and the automatic tool changer from the operator station;
a machining observation window in the guarding at the operator station; and
a first sightline from the operator station through the machining observation window to the working tool, whereby the operator has visual access to the working tool from the operator station.
2. The machine tool of claim 1 , wherein the control panel is usable to enable the operator to program and operate the machine tool.
3. The machine tool of claim 1 wherein the working zone is located at a front of the Y-axis column and is positioned between the Y-axis column and the X-axis of the machine tool, and the first sightline passes in front of the Y-axis column.
4. The machine tool of claim 1 further comprising:
a sightline from the operator station through a tool changer window in the guarding, the sightline providing visual access from the operator station to the automatic tool changer when the automatic tool changer is adjacent to the tool magazine.
5. The machine tool of claim 1 further comprising:
a utilities panel for the machine tool positioned inside of the guarding, the utilities panel containing switches, valves, fill points, filters and gages for the machine tool; and,
an access door in the guarding at the operator station providing access from the operator station to the utilities panel.
6. The machine tool of claim 5 further comprising:
a utilities window in the utilities access door; and
a sightline through the utilities window in the utilities access door providing visual access of the utilities panel from the operator station.
7. The machine tool of claim 6 further comprising:
a tool viewing window in the guarding at the operator station and a further sightline through the tool viewing window, the further sightline providing visual access the tools in the tool magazine from the operator station.
8. The machine tool of claim 1 further comprising:
a workzone access door in the guarding from the operator station to the interior of the machine tool, the workzone access door providing access to the workzone of the machine tool.
9. The machine tool of claim 1 further comprising:
a tool access hatch in the guarding in close proximity to the operator station,
the tool access hatch providing access to the tool magazine for manual removal and replacement of tools in the tool magazine.
