A changeover apparatus for changing between workpiece supports for a machining machine. The changeover apparatus has a base frame with a carrier apparatus for the workpiece supports, which are vertically movable by the carrier apparatus, with the result that one of the workpiece supports can be transferred into a working plane in which the workpiece support is moved from the carrier apparatus into the machining machine and guided out therefrom. A lifting apparatus acts between the base frame and the carrier apparatus and by way of which the carrier apparatus can be vertically moved relative to the base frame for one workpiece support to take up a first lifting position or a further lifting position in the working plane. The lifting apparatus contains a slotted guide, which movably actuates the carrier apparatus with the workpiece supports together between the first lifting position and the further lifting position.

An intelligent plate parts machining production line combining universal equipment and special equipment. Four special machining tools are located on first to fourth stations, respectively, and a universal machining tool is located on a fifth station. The stations are sequential from an automatic feeding device. Truss conveying devices are behind the first to fourth stations, and four mechanical arms are on the truss conveying devices. A four-axis manipulator is between the fourth and fifth stations for transferring materials between the two stations and discharging finished products. Industrial cameras are on the second-station mechanical arm and the four-axis manipulator. Waste boxes are between the first and second stations and between the fourth and fifth stations. A discharging box is on the front side of the fifth station. A scrap conveying mechanism is below the production line. Flexible clamps and sliding rail cylinders are used, so that the production line is flexible.

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.

This gantry type conveying device is provided with: a beam which is horizontally installed; a runner traveling along the beam; an elevator supported to be movable in the vertical direction with respect to the runner; and a loading part which is supported by the lower portion of the elevator and on which a workpiece is loaded. This processing line has the gantry type conveying device and a machine tool. The machine tool is provided with: a base; and a workpiece supporting device provided movable with respect to the base in a forward and backward direction perpendicular to the extending direction of the beam when viewed in a plane.

A management system includes: a plurality of machine tools each including a base plate; a plurality of storage plates; an object holder enabling an object to be placed thereon; a conveying unit including a fetching unit that is configured to secure or release said object holder, and a bridge crane that is configured to move the fetching unit among the base plates and the storage plates; and a control unit controlling the bridge crane to move the fetching unit to where the object holder is located, and controlling the fetching unit to secure the object holder, and controlling the bridge crane to move the fetching unit along with the object holder to another location to release the object holder.

A three-dimensional printer with improved adjustment mechanisms for calibrating the orientation of the build platform and an extrusion assembly to optimize the accuracy of models deposited on the build platform. The printer includes a frame carrying an extrusion assembly proximate the top, and a carriage within. A build platform is mounted on the top of the carriage. Carriage adjustment mechanisms are provided at at least two corners of the carriage for calibrating the orientation of the build platform with respect to the X-Y plane. An extrusion assembly adjustment mechanism is provided at at least one end of the extrusion mechanism for calibrating the orientation of the extrusion mechanism with respect to the Y-axis. A height adjustment mechanism is provided for translating the carriage within the frame along the Z-axis.

Production system for machining workpieces including a transfer comprising receiving and passing on the workpieces for machining from process Station to process Station in a chamber, such as a pressing unit. In the production system, logistical and technological processes are improved by implementing unmanned aerial vehicles (UAV). The UAV is used for process Support monitoring the production process of one of the workpieces or the transfer of the workpieces.

A load lifting device for lifting a load. The load lifting device includes a primary plate, a lifting attachment that receives a hook of an overhead suspender, and a clamping system that can clamp a load onto the lifting device between two jaws. The clamping system can have a coarse adjustment and a fine adjustment. The coarse adjustment selectively connects a jaw to the primary plate at a plurality of discrete connection points, and the fine adjustment mechanism selectively moves a contact point of the first jaw toward a first end portion of the load. A method for lifting a load includes positioning the load lifting device horizontally above a load, clamping the load with a clamping system, and imparting a vertical force on an end portion of the load lifting device to rotate it from horizontal to vertical.
