A technique appropriately controls transfer order of a pallet. A pallet transfer system includes a transfer device, a pallet storage, a work station, a machine tool, and a control device. The control device transfers a second pallet from the work station to the pallet storage when the machining of the workpiece attached to a first pallet is completed in a state where the first pallet is in the machine tool and the second pallet is in the work station, and the control device transfers the first pallet from the machine tool to the work station after completion of the transfer of the second pallet from the work station to the pallet storage, or in parallel with the transfer of the second pallet from the work station to the pallet storage.

The present invention discloses an automatic loading and unloading processing system including: a material storage assembly, which is used to store workpieces; a positioning mechanism which is arranged on a worktable; and a transport mechanism, which is used to transport the workpiece to be processed from on the material storage assembly to on the positioning mechanism and transport the processed workpiece into the material storage assembly, wherein the material storage assembly includes: a material tray; a plurality of fixing bases; a motion mechanism; and a plurality of tooling sub-boards for fixing the workpiece, and the tooling sub-boards are fixed on the fixing base, and the motion mechanism controls the movement of the material tray so that the position of the tooling sub-boards corresponds to the position of the transport mechanism; and the transport mechanism includes: an auxiliary jaw loading and unloading system that is arranged at one support end of the worktable to grab the tooling sub-boards and moves along an X axis and/or Y axis of the machining center; and a main spindle jaw loading and unloading system that is arranged on a machining main spindle to grab the tooling sub-boards grabbed by the auxiliary jaw loading and unloading system and moves along the Z axis of the machining center. The present invention realizes the function of automatic loading and unloading, and improves the working efficiency and the consistency of workpiece processing.

A transmission arrangement for energy and/or signal transmission between a control unit of a machine tool and at least one electronic component, in particular for use in a machining center or a turning and/or milling center. The transmission arrangement is configured to transmit energy and/or signals between electronic components arranged on a pallet and a control unit of a machine tool. The method shows a procedure for automated machining of a workpiece by means of a machine tool, in particular when electronic components are arranged on a pallet on which the workpiece is clamped.

A removal tool including a frame having a first side and a second side defining a longitudinal direction therebetween and a first end and a second end defining a transverse direction therebetween, a pivotable separating mechanism and a stopping mechanism is disclosed. The removal tool may be adapted to remove a portion of a pallet. The pivotable separating mechanism may include a first position and a second position. When the pivotable separating mechanism is moved from the first position to the second position the pivotable separating mechanism is adjusted from a first angle relative to the ground to a second angle relative to the ground. The second angle may be greater than the first angle.

This machine tool is provided with: a bridge which is provided on a base in such a way as to straddle a moving body in a direction (X) perpendicular to a direction of movement (Z) of the moving body at a stroke end (E2) of the moving body; a pallet exchanging arm which is provided above the bridge and which engages with a pallet (P) supported on the moving body and a pallet (P) on a pallet loading station, lifts both pallets (P), and pivots about a vertical axis (Ov) to exchange the two pallets (P); and an arm drive device which is provided projecting upward on the bridge, and which moves the pallet exchanging arm along the vertical axis (Ov) and causes the pallet exchanging arm to pivot about the vertical axis (Ov).

A method and apparatus for delivering workpieces to and from a machine table. This invention also relates to an apparatus for receiving at the machine table workpieces which are delivered to and retrieved by the delivery system. Carts move with respect to a surface, such as a floor surface. The carts move and deliver pallets to a loading station that uses a loading arm to deliver pallets with workpieces to and from a machine table.

Provided is an automated pallet changer in machine tool which enable miniaturization and cost reduction. A drive unit in the automatic pallet changer includes a planetary reduction gear. The planetary reduction gear has a first output shaft and a second output shaft in which, by fixing one of the first and second output shaft, the other functions as an output shaft for driving. The first output shaft is used to pivot the pivoting frame, and the second output shaft is used to move the carry-in/out arm back and forth.

A gripping and positioning assembly for transporting a holding device between different positions includes a coupling arrangement for separably coupling the gripping and positioning assembly to the holding device and holding the holding device securely during transport. The gripping and positioning assembly has an integrated drive for moving the holding device between a hold and a release position to allow the operation of the holding device between a holding and a release position as well as a transporting of the holding device. The coupling arrangement has one or more aligning elements to provide an interlocking connection to the holding device.

The invention relates to a handling system (1000) comprising a handling device (100) that has a carrier device (20) and a handling means (30) which is carried by the carrier device (20), intended for handling workpiece pallets (101, 101a, 101b), and comprises an exchange device (40) having at least two receiving spaces (41a, 41b) designed for receiving workpiece pallets (101, 101a; 101b), and the handling means (30) being designed to move the exchange device (40) relative to the carrier device (20) in a first movement direction X in such a way that both receiving spaces (41a, 41b) are moved together, characterized in that the handling means (30) is also designed to decouple a workpiece pallet (101a, 101b) which is handled by the handling means (30) and received in one of the at least two receiving spaces (41a, 41b) from the exchange device (40) via at least one decoupling device (42a, 42b) in such a way that the decoupled workpiece pallet (101a; 101b) substantially retains its position relative to the carrier device (20) during a movement of the exchange device (40) in the first movement direction X.

An automatic pallet changer 2 includes: a pallet housing unit 11 having a plurality of pallet placement portions; and a pallet transfer unit 12 configured to transfer a pallet P that is at a required pallet placement portion and has an un-machined workpiece W attached thereto to a standby station S2 and configured to transfer a pallet P that is at the standby station S2 and has a machined workpiece W attached thereto to a required pallet placement portion.
