In a cell with linked horizontal processing machining centers, each with two swivel arms for manipulating and changing pallets, which can be conveyed to and from a support in a conveying direction, each horizontal machining center is assigned at least one multi-storey pallet rack which is offset in the conveying direction relative to the front side and in which a pallet through-path is provided, and at least one rack storage and retrieval device with a lifting function transverse to the conveying direction is moveable at least between the pallet racks.

A processing system for processing spectacle lenses and a method for processing spectacle lenses are proposed. The processing system has several processing stations, in particular a milling station, a turning station, a polishing station, a cleaning station and/or a signing station. Furthermore, the processing system has a transport system for transporting the spectacle lenses and/or transport containers for the spectacle lenses. Preferably, the processing system also has a common base frame and/or a common casing for the processing stations. In the processing system and/or with the method, several spectacle lenses can be processed simultaneously in different processing stations.

A milling device having a first milling station with a first workpiece spindle capable of rotating about a first spindle axis A1 intended to receive a first lens blank and with a first milling tool with first cutters capable of rotating about a first milling axis FA1 intended for machining a received first lens blank. At least one second milling station with a second workpiece spindle capable of rotating about a second spindle axis A2 receives a second lens blank, and with a second milling tool with second cutters capable of rotating about a second milling axis FA2 machining the received second lens blank, the spindle axes A1, A2 being aligned parallel to one another, the milling axes FA1, FA2 being aligned parallel to one another, and obliquely aligned to the spindle axes A1, A2. The invention also includes a method for the operation of the milling device.

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.

In a cell with linked horizontal machining centers, each with two swivel arms for manipulating and changing pallets, which can be conveyed to and from a support in a conveying direction, each horizontal machining center is assigned at least one multi-storey pallet rack which is offset in the conveying direction relative to the front side and in which a pallet through-path is provided, and at least one rack storage and retrieval device with a lifting function transverse to the conveying direction is moveable at least between the pallet racks.

A pallet carrying apparatus includes: a first pallet rail; a second pallet rail provided parallel to the first pallet rail; a first pallet feeding mechanism including a first endless belt on which convex portions and concave portions each extending in a belt width direction are formed; a second pallet feeding mechanism including a second endless belt on which convex portions and concave portions each extending in a belt width direction are formed; and a pallet moving mechanism configured to move a pallet. The first and second endless belt are provided in the vertical direction. Concavo-convex portions included in the pallet engage with the convex portions and the concave portions of the first and second endless belts.

A manufacturing cell comprises a machine tool that has a tool carrier carrying a tool unit and has two adjacent workpiece paths oriented in a longitudinal direction. The tool unit can be displaced relative to a machine bed of the machine tool in a transverse direction and in a vertical direction. At least one workpiece carriage per workpiece path can be displaced in the longitudinal direction along the machine tool. The tool unit can be displaced in the longitudinal direction relative to the machine bed and/or relative to the workpiece carriages. The tool carrier overhangs or projects beyond the workpiece paths. The individual workpiece carriage can also be displaced in the longitudinal direction along the workpiece supply. Furthermore, the workpiece supply has at least one lowerable or tiltable stop device per workpiece path.
