An automation cell incorporating elements for performing secondary operations on a machined part is adapted to be disposed adjacent to a machining center for performing the primary operations on the part. The cell incorporates a robotic arm capable of being moved into position with respect to the machining center so as to load machined parts into the machining center and unload primarily machined parts for the performance of secondary operations in the cell. In a preferred embodiment the automation cell performs roll check operations on the primarily machined gear by bringing it into meshed engagement with a master gear and rotating the meshed gears and employing a sensor to monitor the roll-out of the machined gear.

The present disclosure shows a gantry loader having at least one carriage travelable at a horizontal guide rail, in particular for the transport of workpieces between stations of a production system, wherein the carriage has at least one drive. The present energy is characterized in that the carriage has an energy store for the at least partial energy supply of the drive.

A machine tool system includes: a machine tool that machines a workpiece by using a tool attached to a spindle; and a plurality of robots installed inside a machining space of the machine tool and adapted to grip the workpiece and move the workpiece in conformity with the machining performed by the machine tool.

A cable-processing system comprising a cable-processing machine for processing ends of cables. The cable-processing machine has: an input side for receiving the cables; a plurality of cable-processing stations; a cable transport device for transporting at least one cable with a movable gripper; and an output side for discharging a processed cable. The cable transport device has a cable conveying device designed as a multiple-store device having a plurality of cable holders. The multiple-store device is designed as an autonomous or guided transporter. At least one of the grippers is designed as a transfer gripper to remove the cables from the cable holder and to feed them to at least one of the cable-processing stations and/or to at least one further gripper acting as a transfer gripper which can be moved using a frame-supported transfer mechanism to transfer the cable to one of the cable-processing stations.

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 machine tool that attaches and detaches workpieces to and from a spindle in a shorter time includes: a machining mechanism part including a spindle, a tool rest, a first-axis feed mechanism moving the spindle in a a first axis extending along a center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest in a second axis orthogonal to the first axis; a loading mechanism part including holding parts for holding a workpiece, and a third-axis feed mechanism moving the holding parts in a third axis orthogonal to the first axis to position them at the transfer position; and a numerical controller. The numerical controller operates to move the spindle toward the transfer position and to position the holding parts at the transfer position such that the operations at least partially overlap.

A turning device has two turning stations, each with a rotatable work piece spindle to hold a lens blank and each with a turning tool for the machining of a lens blank. A fabrication mechanism for the manufacturing of eyeglass lenses from lens blanks includes a milling device and the turning device, wherein the milling device has at least one milling station with a work piece holder to hold a lens blank and a milling tool for the machining of the lens blank. A loading device is configured to remove lens blanks from the milling device and load them into the turning device. A method for operating such a fabrication mechanism includes simultaneous machining of a third lens blank with the milling tool and a first and a second lens blank with the turning tools.

A workpiece conveying apparatus capable of simultaneously conveying two workpieces includes a body section, a right arm and a left arm, the right arm and the left arm being attached to the body section, the right arm and the left arm being horizontally rotatable, a crossbar connected to the right arm, a first suction device attached to the crossbar, a shifter including an attaching section attached to the crossbar and a driving section configured to move with respect to the attaching section, and a second suction device attached to the driving section. The driving section is pivotally attached to a connector bar attached to the left arm, and the driving section is configured to move with respect to the crossbar on the basis of rotation of the right arm and the left arm.

An automatic method for changing the machining reference frame on a machine for machining parts from bars, notably extruded or molded profile sections, the part to be machined being held during its machining by at least two distinct and independent clamping means each having a longitudinal movement and a rotation on an axis parallel to the long axis of the part to be machined allowing for a relative angular and longitudinal displacement of one relative to the other, a method whereby, in order to proceed with a change of reference frame, one of the clamping means releases the part to be machined and disengages therefrom to turn freely about the long axis of the part independently of the other clamping means, then aligns itself angularly on new clamping references of the part before retaking the latter and allowing for a change of grip by the other clamping means.

A device (1) for the stepwise advancing of workpieces, in which a first swing arm (7) and a second swing arm (11) of a drive unit (8, 9) are respectively designed at each gripping rail (2, 3) of two gripping rails (2, 3), which are arranged in parallel to each other, for detecting and transporting the workpieces in a first end region (4) and a second end region (5), which include a gripping region (6) between them. The first swing arm and the second swing arm engage with the respective gripping rail (2, 3) at a distance from one another and movably retain them along a direction of extension of the gripping rail (2, 3).
