  • Patent number: 8733242
    Abstract: A hauling or towing vehicle has a power take-off shaft that can be activated and deactivated selectively by way of a coupling. The apparatus has drivable elements that can be connected to the power take-off shaft. An electronic control unit of the apparatus is connected via a bus to an electronic control unit of the hauling or towing vehicle. The electronic control unit of the apparatus is connected to a sensor for detecting a living creature present in a danger zone of the machine. In the case that a living creature is detected in the danger zone, the electronic control unit of the apparatus causes the electronic control unit of the hauling or towing vehicle to order an actuator to disconnect the coupling of the power take-off shaft and/or to prevent the actuator from closing the coupling.

  • Patent number: 7698017
    Abstract: The electric press is provided with a main CPU 1 and a sub CPU 3, the main CPU 1 being responsive to a signal from a servo driver 10 to give an detecting signal to a relay 2 when a ram 51 is located in a predetermined position, thereby to give a mute signal to an area sensor 30 and the sub CPU 3 being responsive to a signal from an encoder 9 to give a detecting signal to a relay 4 when the ram is located in a predetermined position, thereby to give a mute signal to the area sensor 30. The main CPU 1 and sub CPU 3 watch each other, that is, the main CPU 1 checks the output of a relay 4 and turns the relay 2 off when the mute signal is not produced from the relay 4. The conditions of sub CPU and main CPU are compared with each other. In case the two conditions are in accord with each other, it is decided that the relay 4 is out of order. The sub CPU 3 makes the same check operation in connection with the relay 2.

  • Patent number: 7454935
    Abstract: A method and an optoelectronic sensor are provided for ensuring the safety of a machine tool having a first tool part carrying out working movements in the direction of a second tool part. The sensor monitors a three-dimensional protected field between the tool parts of the machine tool. At the start of a working movement of a first tool part of the machine tool, the extent of the protected field in the direction of the working movement is smaller than the extent of the open gap between the tool parts. On a continued working movement, the extent of the protected field is continuously reduced and the protected field is held in the center of the open gap. Thereafter, on a further continued working movement, the extent of the protected field is maintained and the protected field is held in the center of the open gap. The sensor is finally deactivated.

  • Patent number: 7286895
    Abstract: A safety device for a machine has a first machine part for carrying out a working movement towards a second machine part. It also has at least a first and a second optical barrier moving along with the first machine part during the working movement. The first optical barrier runs ahead of the first machine part by a first distance, and the second optical barrier is arranged at a second distance from the first optical barrier. A control unit is designed to stop the working movement of the first machine part when the first optical barrier is interrupted. A test unit allows to test whether the second optical barrier has been interrupted once the first machine part has been stopped. A blocking unit serves for blocking the working movement as a function of the test result from the test unit. Using this safety device it is possible to determine an overtravel of the first machine part in a simple and reliable manner.

  • Patent number: 7143617
    Abstract: A press forming machines includes displacement measuring means for measuring a displacement between a slide plate and a reference plate. Control means measures a positional displacement of each of the driving sources by using the displacement measuring means in each of a plurality of operating steps during the molding operation, detects a desired displacement position of the entire slide plate, extracts control data including a correction amount to maintain the entire slide plate at the desired displacement position, the correction amount corresponding to a change in load on each of the driving sources, stores the control data in the memory, supplies the control data to the driving sources, and separately drives the driving sources. Since an actual molding operation can be performed using control data generated in a trial molding operation, the cycle time of the actual molding can be shortened.
