Definitions

  • the invention relates to a system for the bodywork according to the preamble of patent claim 1.
  • a system for the bodywork of the type mentioned is basically known from the document DE 201 21 630 Ul.
  • This system consists of a central control unit typically accommodated in a control cabinet (called a higher-level controller there) and an electrically operated actuating device (called a clamping device there) having its own control unit for controlling its movement. While it is not explicitly mentioned in the cited document, the person skilled in the art knows that such a system always consists of several (ie at least two) actuators, in each case directly connected to the central control unit.
  • an actuating device is generally to be understood as a tensioning device, a pivoting device, a centering device or a positioning device or the like.
  • the invention has for its object to improve a system for the body of the type mentioned.
  • a system for bodywork with reduced cabling is to be created.
  • control unit 5 of one of the two actuating devices is connected to the central control unit via the control unit of the other of the two actuating devices.
  • the solution according to the invention is thus distinguished by the fact that, although a control unit of a first actuating device is connected directly to the central control unit, at least one control unit of a second actuating device no longer acts directly, but only indirectly is formed connected to the central control unit via the control unit of the first actuating devices.
  • control units of the actuating devices are designed as data processing units provided for transmitting, receiving and processing data packets.
  • Actu-20 gungsvoriques thus becomes a "smart" actuator, which is preferably operated, for example, during setup even on its own graphical user interface, with the result that the device no longer as before on one on the central control unit 25 accessing programmer must be done, but can easily be done on the electromechanically trained personnel.
  • the actuator in this document is called a "swing clamp", but this is not correct since it is actually a pivot and not a tensioner.
  • the difference between these two devices 15 is that a pivoting device is used to pivot an object between two positions with a fixed torque, while a clamping device for clamping an object with a demand-adjustable force is used.
  • a pivoting device is used to pivot an object between two positions with a fixed torque
  • a clamping device for clamping an object with a demand-adjustable force is used.
  • FIGS. 1 and 2 is the cited document.
  • FIG. 1 schematically shows the system according to the invention for the carcass construction with a central control unit and three actuating devices

  • the actuating device In order to be able to form the actuating device particularly small or at least 5 at least as small as comparable pneumatic actuating devices, it is furthermore particularly preferred for the actuating device to be grease-lubricated and not oil-lubricated.
  • the compact design of a grease-lubricated actuator results from the fact that the spaces for the components to be lubricated must be kept small so that the grease does not accumulate in a place that does not need to be lubricated.
  • control unit 2.1 is one of the two actuators 2 connected via the control unit 2.1 of the other of the two actuators 2 connected to the central control unit 1.

  • each data processing unit of the 5 control units 2.1 and / or an additional data processing unit provided on each actuating device 2 are provided with software for realizing security functions, in particular one or the said STO security function or that such software is installed.
  • This requirement leads to an autonomous functional safety function of each individual actuating device 2, wherein the said integrated STO safety function can abruptly stop the electric motor 7, namely completely independently of possible information coming from the central control unit 1.
  • the said safety function can furthermore be implemented particularly well together with an actuating device 2 with a self-locking gear, in particular the worm gear mentioned below.

  • the system according to the invention for body construction belongs to a completely new generation of such systems, because the new concept allows a previously unattained ease of use, which begins with the very simple wiring 3 of the actuation devices 2 and with the user-friendly adjustability of the entire system via a graphical user interface, for example on a mobile device such as tablet computer ends.
