In a device for manipulating workpiece pallets, with two parallel pivot arms, each of which can each be fitted with a pallet carrier, each of which is swivelled by a motor and a swivel gear about a substantially horizontal swivel axis, with each pallet carrier on the swivel arm being able to be turned parallel to the other pallet carrier by a motor and a gear about a swivel axis in parallel to the turning axis. In said device, the motors are electric motors, the gear is a combined beveled planetary gear and the swivel arms via a line shaft are mutually coupled for torsional strength.

A reclamping device for reclamping a workpiece between two vices has a handling device for positioning and actuating the two vices and a reclamping station which contains a carrier for holding a first vice in an accurate position. The reclamping station contains a pressure device with a pressure plunger movable relative to the carrier by an actuator for pressing the workpiece against the first vice positioned on the carrier.

A machine tool system is provided that includes at least one machine tool for machining workpieces. A workpiece holding device is provided that holds one or more workpieces during machining using an adapter. A positioning device positions workpiece blanks on the adapters. An adapter loading and transporting device, which has an adapter gripping device that acts on the adapters and moves adapters that are provided with workpiece blanks from the positioning device to the at least one machine tool, loads the at least one machine tool and unloads adapters that are provided with machined workpieces from the at least one machine tool. A workpiece transporting device is provided which has a workpiece gripping device that acts on workpieces. After machined workpieces have been unloaded by the adapter loading and transporting device, the workpiece transporting device takes the workpieces up from the adapter loading and transporting device and removes them.

A machine tool comprises a tool spindle which can be positioned in 3 axes and a pivot bridge pivotable about an A axis with a round table for mounting a workpiece pallet supporting a workpiece. Furthermore, in front of the pivot bridge, a mount is provided for a processed workpiece or workpiece to be processed located on a workpiece pallet. Between the mount and the pivot bridge a pallet changer is provided which can only perform a vertical displacement movement and a pivot movement about a vertical axis. Workpiece pallets are picked up and put down only during the vertical displacement movement of the pallet changer, or possibly by pivoting the pivot bridge about the A axis.

A table clamp device includes a reference rail, a slider section, and a movement mechanism. The reference rail is provided on a mounting surface of a base on which a rotary table is rotatably supported. The rotary table has a first engagement part. The slider section is provided to slide along the reference rail and has a second engagement part. The movement mechanism moves the slider section along the reference rail so that the second engagement part engages with the first engagement part such that the rotary table is positioned and clamped to the base.

A machine tool includes a main machine, a pallet change unit, a main body cover, a machine entry door, an internal machine cover, and an internal entrance area. The main machine is configured to machine a workpiece. The pallet change unit is adjacent to the main machine. The main body cover is provided on the pallet change unit. The machine entry door is provided in the main body cover. The internal machine cover is connected to the machine entry door. The internal entrance area is defined by the machine entry door and the internal machine cover. The machine entry door and the internal machine cover are constructed to sweep the internal entrance area.

A table clamp device includes a reference rail, a slider section, and a movement mechanism. The reference rail is provided on a mounting surface of a base on which a rotary table is rotatably supported. The rotary table has a first engagement part. The slider section is provided to slide along the reference rail and has a second engagement part. The movement mechanism moves the slider section along the reference rail so that the second engagement part engages with the first engagement part such that the rotary table is positioned and clamped to the base.

A clamping device and a method for handling a workpiece or a unit comprising a workpiece and a workpiece holder. An automatic workpiece exchange is enabled by using a tool spindle. For this a spindle adapter is present that can be releasably connected with the workpiece holder. By means of the spindle adapter, the unit comprising the workpiece and the workpiece holder can be transported. The clamping device can be switched between a release condition and a clamping condition by means of a movement of an operating element. This movement can be carried out by means of the tool spindle, in that the tool spindle engages the operating element directly or indirectly by means of the spindle adapter or an operating tool.

A substrate production system includes a component mounter having a component supply area in which a component supply unit is disposed, and configured to pick up a component from the component supply unit and mount the picked up component on a substrate, a kitting station provided in a substrate production line in which multiple substrate production machines including the component mounter are arranged, and configured to set a component container containing multiple components in the component supply unit, and a conveyance device configured to convey the component supply unit in which the component container is set by the kitting station to the component mounter.

The present invention includes a pallet storage device (30) having holding units (31, 32, 33) holding pallets (P) and a frame (40) supporting the holding units (31, 32, 33), a conveyance device (10) having a traveling base (11) having a traveling path (11a) extending along the pallet storage device (30) and a conveyance unit (15) loading and unloading the pallets (P) into and from the holding units (31, 32, 33) and conveying the pallets (P) to and from a predetermined place, and a controller (60) controlling operation of the conveyance device (10). The frame (40) has a space capable of receiving the controller (60) therein and has a plate-shaped cover (43, 48, 51) arranged to be located above the controller (60) and inclined downward toward the traveling base (11) side. The cover (43, 48, 51) is supported by the frame (40) such that a lower end of the cover (43, 48, 51) can be flipped up, and the cover (40) is configured such that the controller (60) can pass under the cover (43, 48, 51) when the lower end of the cover (43, 48, 51) is in a flipped-up state.
