A pressing device for pressing meat products, in particular frozen and/or partly frozen meat products, preferably fresh meat products and/or bacon, comprises a pressing chamber which extends along a longitudinal axis and into which a product to be pressed can be inserted, wherein the pressing chamber comprises at least one counter-element and at least one contact element, which is movable in the direction of the counter-element, that cooperate such that the product inserted into the pressing chamber can be compressed between the at least one counter-element and the at least one contact element; and wherein the pressing device comprises at least one servomotor that is configured to move the at least one contact element.

In a method of pressing and processing meat products, in particular frozen and/or partly frozen meat products, preferably fresh meat products and/or bacon, the products are inserted into a pressing chamber of a pressing device and are pressed in the pressing chamber by at least one displaceable contact element, with the contact element being moved by means of a servomotor.

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.

A press machine includes a display unit which displays a first image in a circular shape corresponding to a rotation of an eccentric mechanism and representing one stroke of slide operation and a second image in a circular-arc shape corresponding to an operation of an attachment device interlocked with the press machine, and an operation unit which receives an input operation. The first image indicates at least one slide operation region. The second image is placed concentrically with the first image in relation to the slide operation region. The second image has opposed ends each allowed to move in response to the input operation in a direction in which the second image extends.

A method for pressing a workpiece with a predetermined pressing force uses a forming tool coupled with an electric motor via a spindle drive that converts the rotational movement of the electric motor drive shaft to a translational movement of the forming tool. The method includes: accelerating the electric motor in a first rotational direction to a predetermined maximal speed of rotation; operating the electric motor at the maximal speed until the drive shaft has completed a predetermined number of revolutions; reducing the speed of rotation of the electric motor to a predetermined reduced speed of rotation; operating the electric motor at the reduced speed until a pressing force increase exceeding a predetermined threshold value is detected by a measuring unit that follows the electric motor; forming the workpiece with constant detection of the pressing force by the measuring unit until the predetermined pressing force has been reached.

A die cushion control device for controlling a die cushion mechanism includes: a pressure command generation unit that outputs a first pressure command on pressure or force to be generated between the die cushion mechanism and a slide; a deviation prediction unit that predicts a pressure deviation that is the difference between the pressure or the force in the first pressure command and a detected pressure caused when the die cushion mechanism is controlled according to the first pressure command, and outputs the predicted pressure deviation as a correction pressure command; a pressure command correction unit that corrects the first pressure command with the correction pressure command to calculate a second pressure command; and a pressure control unit that calculates a speed command to cause the detected pressure to follow the second pressure command, and outputs the speed command to a speed control unit.

The invention relates to a work machine, comprising a mast having a mast head, a support cable which is guided along the mast, over the mast head, a cable winch comprising a rotatably mounted winding drum to which the support cable is attached for winding up and unwinding, a work element which is arranged on the support cable for vertical movement, and a control unit, by means of which the cable winch can be operated in an unwinding mode, for unwinding the support cable from the winding drum, in which mode the work element is lowered, on the support cable, as far as a base surface. According to the invention, a cable contact pressure means comprising at least one contact pressure element is provided, which element can be adjusted into a contact pressure position by the control unit, by means of an actuating member, in order to counteract a cable oscillation of the support cable when the base surface is struck, in which contact pressure position the contact pressure element rests on the support cable at a contact pressure force.

A multi-axis motor control system includes a host control apparatus, motors, motor control apparatuses that drives the motors and each includes circuitry that acquires control related information transmitted and received between the host control apparatus and at least one other motor control apparatus, and controls a corresponding motor of the motors based on the control related information, and a communication channel that connects the host control apparatus and the motor control apparatuses in series.

A press device includes a slide, a bolster disposed below the slide, a servomotor configured to drive the slide, a power storage unit, a current detector, and a control unit. An upper die can be mounted on the slide. A lower die can be placed on the bolster. The power storage unit is configured to be able to supply stored power to the servomotor. The current detector detects current supplied from the power storage unit. The control unit performs stop control to stop supply of current from the power storage unit to the servomotor based on a detection value of the current detector.
