摘要： A method for monitoring and assessing correct position Pi of a work slide of a wedge drive tool in a press, without a position sensor. The slide of the wedge drive tool is actuated from an end position (XE) back to the starting position (XA) of the slide by a spring. The spring is arranged in the wedge drive tool. The press is opened from a lower press position to an upper press position while a slide bed of the wedge drive tool is relieved. The position of the slide is indirectly detected in that at least the restoring force of the spring is detected and evaluated.

摘要： Press-fitting work is evaluated by appropriately determining a load when sliding occurs. A load-drop determination unit determines whether or not a load value detected by a load detecting unit exceeds a load-drop determination value decided based on a moving average value and a dispersion average value stored in a storage unit. A data substitution unit substitutes the load value which is determined to exceed the load-drop determination value in the load-drop determination unit with a predetermined value.

摘要： Disclosed herein is a press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors configured to provide a first output signal indicative of deformation of the first sensing part. The method can be configured for determining if an error criterion based on the first output signal from the first displacement sensor has been met, and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.

摘要： A system collects training data in order to train a determination model of artificial intelligence that determines an abnormality of an industrial machine. The system includes a storage device and a processor. The storage device stores state data indicative of a state of the industrial machine acquired in time series. The processor determines an occurrence of a trigger related to an occurrence of the abnormality in the industrial machine, and extracts data corresponding to the trigger from the state data when the trigger occurs. The processor stores the data corresponding to the trigger as the training data.

摘要： A waste treatment machine is disclosed, having a safety sensor which generates an alarm signal to stop the motor (7) when the requested torque exceeds a certain threshold, but has a gear with a friction transmission belt (8), i.e. not a toothed belt, between a driving pulley (9) and an idle pulley (10) connected to a shaft (6) for squeezing/grinding waste. The friction transmission belt is tightened so as to slip when a nominal maximum torque is exceeded. The protection sensor is configured to detect slippage of the friction transmission belt and to provide in such an event an alarm signal to a control unit that interrupts a normal miming of the motor. The organic waste treatment machine may be a single-worm screw (4) or double-worm screw squeezing machine, or a grinding machine with hammers (13) pivoted at the periphery of a shaft installed in the inner chamber of the machine. A method of controlling such a machine for treating waste is also disclosed.

摘要： A writing instrument compressing device includes a base having an underside mounted to multiple raiser pieces to have the base separate from a carrying surface by a distance in a vertical direction. The base includes an elongate hole that is delimited by two opposite sidewalls each including tooth ridges and the tooth troughs alternately arranged. A handle rod is pivoted to an end of the base to drive reciprocal movement of a pusher. A retainer is reciprocally movable along the elongate hole of the base and functions to clamp and fix a writing instrument body or a tool. The retainer is provided, on a bottom thereof, with a screw rod extending through the elongate hole of the base. A tightening assembly includes a nut and a rotation bar horizontally penetrating through the nut and having two ends selectively moved close to the nut.

摘要： In a hydraulic drive of a tool piston in a cylinder first and second flat contact areas each are contiguous, when moving into and in the open position of the valve member between the detent element and the valve member, wherein a pressure-limiting valve that can be loaded with the pressure in the cylinder from a closed position to an open position and a detent element loaded by a spring in the locking direction to positively hold a neck of a valve member of the pressure-limiting valve are arranged in the open position, wherein the detent element at least via the tool piston at its return to a released position can be moved and, when moving the valve member to the open position of the pressure-limiting valve, non-positively acts on the valve member.

摘要： A control system includes a load detector, a determination unit, and a drive control unit. The load detector detects a load of a slide. The load of the slide includes a positive load due to a pressing force of the slide during pressing and a negative load at the time of a breakthrough. The determination unit determines whether to execute emergency stopping of the slide based on the positive load and the negative load detected by the load detector. The drive control unit controls the driving of the slide based on the determination result of the determination unit.

摘要： A machine has a first machine part and a second machine part. The first machine part carries out a working movement towards the second machine part in order to machine a workpiece. The first machine part has a leading edge, which defines a movement plane in the course of the working movement. For safeguarding the machine, a plurality of images including spatially resolved representations of the edge, at least a part of the workpiece, and a protective region defined between the edge and the second machine part are acquired. A motion speed of the first machine part relative to the second machine part is determined on the basis of the plurality of images. The motion speed is compared to a reference speed value or speed profile, defining a nominal speed of the first machine part relative to the second machine part during the working movement and an acceptable tolerance interval. The working movement is stopped if the motion speed deviates from the reference speed beyond the tolerance interval.
