The container is also movable with respect to the device to select the location of the tool to be changed.

Abstract: In the tool change device, a tool change arm 27 for changing a tool 25 with respect to a main spindle 24, a main tool magazine 29 including a plurality of hold grooves 30 arranged linearly for holding the tools 25, and a tool storage member 41 including at least one storage portion 46 for storing the tool 25 are arranged in the back-and-forth direction of the tool change device. In order that the tools 25 can be delivered between the tool change arm 27 and main tool magazine 29, between the main tool magazine 29 and tool storage member 41, and between the tool storage member 41 and tool change arm 27, a single tool loader L is disposed in such a manner that it can be moved in correspondence to the tool change arm 27, main tool magazine 29 and tool storage member 41.

Abstract: An automatic pallet handling system for a machine tool is described in which the pallets are formed as lightweight cassettes (10) which can be mounted by means of shaped locating features on the external periphery of a receiving device (4) mounted, for example, for rotation with a horizontal indexing spindle (2) in a vertical spindle CNC machine. A portable cassette-loading system (15) which consists of a chain conveyor (17) having links (18) pivotably connected side-by-side and formed from lightweight extrusions is positionable adjacent the machine or removable to a loading station. The extruded links form features for engaging the same cassette-locating features on the cassettes and a transfer mechanism (50) slides the cassettes from the loading conveyor to the periphery of the receiving device.

Abstract: A machine magazine to receive a plurality of tools that can be moved in a first transport direction is associated with a machine tool. Also provided is a changing magazine to receive a plurality of tools that can be moved in a second transport direction, which tools are to be inserted into or removed from the machine magazine.

Abstract: A punch press provided with a tool magazine in which a plurality of tool mounting gondolas are supported movably in a vertical loop by and between two endless chains arranged vertically around sprocket wheels. Each gondola is supported at its supporting points which differ from each other at least in height, whereby the gondola is moved around in the loop without overturn when the sprocket wheels are rotated by a motor. Each of the gondolas stays at a manually tool changing location of the magazine where a table is provided for changing a number of tool assemblies in the magazine. The table has at least one guide which is positioned at two different heights, and along the guide tool assemblies or an upper and a lower die holders are drawn out of the gondola horizontally and placed in desired positions for replacement.

Abstract: A tool changer is provided in which a rotary tray positioned beneath the forward edge of a machine tool supports a large number of tools in individual cartridges. A tool changer head includes two outwardly projecting tubular members and can be rotated about a horizontal axis, moved vertically and pivoted about a vertical axis. A vacuum or positive pressure can be generated in the tubular members. Therefore, the tubular members can be positioned over a tool in one of the cartridges after which the tool changer head is raised and rotated to extend the tool into the spindle of a machine tool which has been run past the forward edge of the machine. Negative pressure will withdraw the tool from the cartridge and positive pressure will drive the tool into the spindle. Similarly, a tool can be removed from the spindle by negative pressure and reinserted into the cartridge by positive pressure.

Abstract: The tool or workpiece magazine has tool holders disposed on a circle, from which holders the tools or workpieces can be removed by means of a removing device disposed centrally relative to the circular arc. This removing device comprises a column which is turnable around the axis thereof and on which a carriage is axially and slidably mounted. The carriage in turn carries transversely extendable telescoping arms, at the free end of which there is disposed a gripper having gripping jaws. Slots in tool carriers attached horizontally on movable panels are used as tool or workpiece holders. The panels can be moved outward of the magazine for stocking purposes.
