Control method for a press installation and installation, where the installation includes a servo press, a conveyor device for conveying pieces from a position of origin to the servo press, and a controller. The controller controls the movements of the conveyor device and of the servo press by means of one and the same master signal, causing a synchronized actuation of both. In the method, the pieces are conveyed to the position of origin and during the travel thereof until reaching the position of origin, the passage of the pieces through a predetermined position of reference before the position of origin is detected, and depending on the detection, the master signal is adjusted for adapting the actuation speed of the servo press.

An operation control device for a press line in which a first conveyance controller transmits, to a first press controller, time at which a first conveying device exits an interference region in which the first conveying device interferes with a first press machine; the first press controller controls the first press machine so that, at or after a time at which the first conveying device exits the interference region, a slide of the first press machine enters the interference region in which the first press machine interferes with the first conveying device, and transmits, to a second conveyance controller, time at which the slide of the first press machine exits an interference region in which the first press machine interferes with a second conveying device; and the second conveyance controller controls the second conveying device so that, at or after a time at which the slide of the first press machine exits the interference region, the second conveying device enters an interference region in which the second conveying device interferes with the first press machine.

A control device, a system and methods for optimizing and providing movement profiles, wherein the movement profiles serve for determining the movement of tools of a press and the movement of a receiving element for a workpiece of a transfer system, where transfer movement profiles are synchronized with one another via press movement profiles, the synchronization of the transfer movement profiles particularly occurs by chronologically shifting synchronization points via boundary conditions such that an offset of the press movement profiles can be determined via the synchronization, so that the workpiece can be processed as quickly as possible through the system.

A voltage signal adaptor includes a housing, a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die comprising one or more die sensors, and a cable receptacle communicatively coupled to the die cable. The cable receptacle is engageable with a bolster cable of a machine press communicatively coupled to a press line programmable logic controller. The voltage signal adaptor further includes a step down power supply positioned between and communicatively coupled to the cable receptacle and the die cable and one or more signal conversion switches positioned between and communicatively coupled to the cable receptacle and the die cable.

A method for operating a punching press with a press plunger driven by a crank drive, which operates in a machining zone of the punching press against a stationary clamping plate, and with a servo feed apparatus for intermittently feeding a band of material to be processed to the machining zone. In punching mode, the press plunger is moved back and forth by the crank drive between a first movement dead point (0), in which the press plunger is at maximum distance from the clamping plate, and a second movement dead point (180), in which the press plunger is at minimum distance from the clamping plate. In the process, the material band is pushed by the servo feed apparatus around the first movement dead point (0) in a first rotation angle window (3) of the crank drive by a certain length into the machining zone and processed in a second rotation angle window during the feed pauses. The feed movement of the servo feed drive takes place according to an electronically defined feed movement profile (5), which is followed in the first rotation angle window (3) in an electronically synchronized manner to the rotation of the crank drive (4). When a press stop (6) is triggered in the first rotation angle window (3), the synchronization of the feed movement profile (5) with the rotation of the crank drive (4) is canceled and the feed movement profile (5) is moved to the end independently of the rotation of the crank drive (4). This mode of operation reduces the maximum torque requirement of the feed axes for servo feeds operated angularly synchronously with the crank drive of the press plunger, so that smaller and therefore more cost-effective servo drives can be used or more load can be moved with a given servo drive.

A press system and method that can easily avoid collisions and improve productivity regardless of a workpiece conveyance pattern by a workpiece conveyance device. Press devices Pn and Pn+1 each send signals corresponding to an angle of a crankshaft to a line controller, and robots Rm, Rm1, and Rm+1 each send signals corresponding to a state of conveyance of a workpiece to the line controller. The line controller, based on the signals, determines whether to permit entry to each of the multiple regions C1 to C10. It then sends an entry permission signal for each of the multiple regions C1 to C10 to the robot Rm based on determined results, and the robot Rm performs loading or unloading based on the entry permission signal.
