Definitions

  • the invention relates to a device for transmitting data, signals and / or energy according to the kind defined in the preamble of claim 1.
  • Sliding contacts are also used to transfer energy to moving machine parts and / or machine units.
  • the coupling to the moving machine unit or the machine part is only required temporarily and in certain, unchangeable positions, it is made with touching plug connections or an end face contact carried out. Since the moving machine parts and / or machine units are often equipped with a large number of electrical sensors and actuators, which on the one hand require the supply of electrical energy and on the other hand make it necessary to couple the electrical input and output signals to the machine control, the devices described have a transmission of electrical energy and for control engineering coupling many disadvantages.
  • the present invention is therefore based on the object of providing a method for transmitting data, signals and energy to the sliding table and / or the transfer device of a shaping machine and measures for carrying out the method, which does not have the disadvantages of the prior art, in particular that is free of wear and tear and requires relatively little maintenance and control.
  • a device for performing the method is proposed in claim 5.
  • both the fixed device and the movable device can be prefabricated as an entire assembly and then attached to a desired location on the forming machine.
  • the energy is transmitted from an energy source or energy sink 1 to a converter 2, which transmits the energy to a transmission system 3.
  • the transmission of the energy takes place in a contactless manner in the transmission system 3, after which the transmitted energy is passed on to a further converter 2, which is then transferred transfers the energy to a consumer 4, not shown.
  • the contactless transmission of data and signals takes place.
  • the data and / or signals are transmitted from a data source or data sink 5 to a modulator / demodulator 6, the data then being forwarded to the transmission system 3 in the form of an AC voltage.
  • the contactless data transmission takes place in the transmission system 3, after which the data are forwarded to a further modulator / demodulator 6, in which the data are converted back into the original signal form. From the second modulator / demodulator 6, the data and / or signals are again forwarded to a data source or data sink 5.
  • the entire method that is to say both the energy transmission and the transmission of data and signals, can be unidirectional or, as indicated by the double arrows in FIG. 1, bidirectional.
  • the method described is known per se, but has not previously been used in forming machines, more precisely in sliding tables and / or transfer devices on forming machines.
  • FIG. 2 schematically shows a top view of a forming machine, of which only the press stands 7 are shown in the view according to FIG. 2.
  • a sliding table 8 is arranged between the press stands 7.
  • the sliding table 8 can be moved linearly on rails 9, the second sliding table 10 shown in FIG. 2 also being movable at right angles.
  • T-Track The arrangement of the rails 9 shown in FIG. 2, that is to say the right-angled arrangement of two rail paths, is referred to as the "T-Track".
  • installation spaces are provided for devices for the contactless transmission of data, signals and energy.
  • the installation spaces 11, 12 and thus also the devices arranged in the installation spaces 11, 12 run parallel to the rails 9.
  • the installation spaces 11, 12 are preferably sunk in the hallway, so that the space next to the press is available for other purposes. Furthermore, the sinking of the installation spaces 11, 12 in the floor has the advantage that the risk of accidents for the press operating personnel is low due to the large amount of energy transmitted.
  • Fig. 3 shows a section through the installation space 11 along the line III-III of Fig. 2.
  • a base plate 13 is fastened on which a transmitter 14 for energy and a first coupler 15 for data are attached.
  • a coupling loop 16 for energy is guided on the base plate 13 from the transformer 14.
  • a first antenna 17 is guided parallel to the longitudinal axis of the base plate 13.
  • the transmitter 14, the first coupler 15, the coupling loop 16 and the first antenna 17 are fixedly attached to the base plate 13 and are therefore to be referred to below as a fixed device 18. Likewise, the base plate 13 is firmly attached in the installation space 11.
  • a further base plate 19 is arranged on the sliding table 8, on which a second transmitter 20 for energy and a second antenna 21 for data are fastened.
  • the second transformer 20 is designed so that it has two openings through which the coupling loop 16 is carried out.
  • the second antenna 21 is arranged at the same height level as the first antenna 17 on the base plate 13.
  • the transmission of data takes place from the first coupler 15 into the first antenna 17 and from there without contact into the second antenna 21, from where the data are transmitted to a data sink via at least one line.
  • the energy or data and signal transmission can also be in the other direction, i.e. also bidirectional.
  • the base plate 19, the second transmitter 20 and the second antenna 21 also move with the sliding table 8 during the movement thereof, the arrangement described will be referred to below as a movable device 22.
  • the fixed device 18 and the movable device 22 thus represent the transmission system identified by the reference number 3 in FIG. 1.
  • Fig. 4 shows a section through the installation space 11 of Fig. 2 along the line IV-IV.
  • the openings in the second transformer 20 are particularly clearly visible, the coupling loop 16 being guided through the openings. Furthermore, the level of the second antenna 21 with the first antenna 17 is clearly recognizable.
  • the second transmitter 20 and the second antenna 21 are connected to the base plate 19 via connecting links, which in the present exemplary embodiment are designed as pins 23. If the pins 23 are adjustable in length, the distance between the second transmitter 20 and the second antenna 21 from the base plate 19 can be adjusted. This makes it possible in particular to compensate for tolerances which arise from the movement of the sliding table 8 on the rails 9, so that trouble-free energy or data and signal transmission is always ensured throughout the entire displacement path of the sliding table 8.
  • the second transformer 20 is connected to an intermediate member 24, the intermediate member 24 being guided in guides 25 which are attached to the base plate 13 of the fixed device 18 are.
  • This also always guarantees a uniform and constant transmission of data, signals and energy from the fixed device 18 to the movable device 22.
  • the movable device 22 is connected to the fixed device 18 via the pins 23, the second transmitter 20 and the guides 25 to the fixed device 18. If the use of the guide 25 is dispensed with, it can happen that the second antenna 21 begins to oscillate when the sliding table 8 is accelerated and / or braked such that interference-free data transmission is no longer possible. The same also applies to the transmission of energy from the coupling loop 16 to the second transformer 20.
  • a fixed device 18 is preferably arranged between the press stands of the press.
  • the movable device can then be arranged on a machine part which is movable relative to the fixed device 18 and which also carries out a linear movement with respect to the fixed device 18.
  • the fixed device 18 is advantageously arranged on the shaping machine on at least one traverse extending transversely to the transfer direction.
  • FIG. 5 shows only by way of example how the fixed device 18 can be arranged, for example, on a crossbar or the press stand, while on a transfer rail 26 the movable device 22 (not visible here) which is complementary to the fixed device 18 is attached.
  • the method according to the invention can also be used on supply and discharge devices for blanks on forming machines. Since the basic structure of supply and discharge devices for circuit boards largely resembles that of the transfer device, the description of an exemplary embodiment should be omitted here.
  • the energy can be transmitted inductively, while capacitive coupling is also possible in addition to the inductive transmission when transmitting data and signals.
  • capacitive coupling is also possible in addition to the inductive transmission when transmitting data and signals.
