Definitions
- the invention relates to a method and an apparatus for transmitting Forming data, signals and energy in or on presses, punching machines or the like Machinery.
- the coupling to the moving machine unit or machine part for example a sliding table and / or the transfer device of the forming Machines and / or a feed or discharge device for blanks, only required temporarily and in certain, unchangeable positions is, it is with touching plug connections or through face contact carried out Since the moving machine parts and / or machine units often with a variety of electrical sensors and actuators are equipped, which on the one hand need a supply of electrical energy and on the other hand a coupling of the make electrical input and output signals to the machine control necessary, have the described devices for the transmission of electrical energy and for control engineering coupling many disadvantages
- EP-A1 0 525 459 describes a device for contactless transmission electrical energy known in the manner of a transformer with a core of one ferromagnetic material on which a primary winding and a secondary winding are put on. These windings are a transmitter on the one hand, and a on the other Assigned recipient. These are alternately on a transmitter and a Switchable receiving electronics This arrangement makes it possible to switch electrical Energy and at the same time alternating signals between mutually adjustable Transfer components.
- the present invention is therefore based on the object of a method for Transfer of data, signals and energy to the sliding table and / or the Transfer device of a forming machine and measures for implementation to provide the method which has the disadvantages of the prior art does not have, in particular that is wear-free and has a relatively low maintenance and Control effort.
- the energy is converted into an energy source or energy sink 1 Transfer converter 2, which forwards the energy to a transmission system 3.
- a transmission system 3 In the transmission system 3 is the contactless transmission of the energy, after which the transmitted energy is forwarded to a further converter 2, which then transmits the energy to a consumer 4, not shown.
- the contactless transmission of data and Signals From a data source or data sink 5, the data and / or Signals are transmitted to a modulator / demodulator 6, the data thereafter in the form an AC voltage can be forwarded to the transmission system 3.
- 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 is converted back to the original waveform. Of the data and / or signals are again from the second modulator / demodulator 6 forwarded to a data source or data sink 5.
- the entire process i.e. both the energy transfer and the Transmission of data and signals can be unidirectional, or as shown in FIG. 1 the double arrows indicated, run bidirectionally.
- FIG. 2 shows schematically a top view a forming machine, of which in the view according to FIG. 2 only Press stand 7 are shown. There is a sliding table 8 between the press stands 7 arranged.
- the sliding table 8 can be moved linearly on rails 9, the one in FIG.
- the second sliding table 10 shown can also be moved at right angles.
- T-Track The arrangement of the rails 9 shown in FIG. 2, that is to say the right-angled one Arrangement of two rail tracks, is called "T-Track".
- the installation spaces 11, 12 and thus also those in the installation spaces 11, 12 arranged devices run parallel to the rails 9.
- the installation spaces 11, 12 are preferably sunk in the hallway, so that the next the press has available space for other purposes. Furthermore results the sinking of the installation spaces 11, 12 in the bottom of the advantage that the Risk of accidents for the operating personnel of the press due to the large transmission Amount of energy is low.
- Fig. 3 shows a section through the installation space 11 along the line III-III of Fig. 2.
- a base plate 13 is attached, on which a transmitter 14 for energy, as well as a first coupler 15 for data are attached.
- the transmitter 14, the first coupler 15, the coupling loop 16 and the first Antenna 17 are firmly attached to the base plate 13 and are therefore to be referred to below fixed device 18 are referred to.
- the base plate 13 is fixed in the installation space 11 attached.
- 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 attached are.
- 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 sliding table 8 If the sliding table 8 is now moved linearly, it can during the process and also in every stop position of the sliding table 8 energy on the sliding table are transmitted, namely from the transmitter 14 into the coupling loop 16 and from there without contact to the second transformer 20, from which the energy is transferred a line is forwarded to consumers on the sliding table 8.
- Data is transmitted from the first coupler 15 to the first Antenna 17 and from there contactlessly into the second antenna 21, from where the Data is transmitted to a data sink via at least one line.
- the energy or data and signal transmission can also be carried out in the other direction, i.e. also bidirectional.
- the described arrangement are referred to below as a movable device 22.
- FIG. 4 shows a section through the installation space 11 of FIG. 2 along the line IV-IV.
- the openings in the second transmitter 20 are in particular 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 clear recognizable.
- the second transmitter 20 and the second antenna 21 are with the base plate 19 connected via links, which in the present embodiment are designed as pins 23. If the pins 23 are made adjustable in length, then the distance of the second transmitter 20 and the second antenna 21 from the Base plate 19 can be adjusted. This allows tolerances in particular compensate, which by moving the sliding table 8 on the rails 9th arise so that during the entire displacement of the sliding table 8 always one trouble-free energy or data and signal transmission is guaranteed.
- the second transformer 20 is connected to an intermediate member 24, the intermediate member 24 in guides 25 is guided, which is attached to the base plate 13 of the fixed device 18 are.
- This also ensures an even and constant transmission of Data, signals and energy from the fixed device 18 to the mobile device Facility 22 guaranteed.
- the guide 25 Will on the If the guide 25 is not used, it can happen that the second antenna 21 to swing when accelerating and / or braking the sliding table 8 begins that interference-free data transmission is no longer possible.
- FIG. 5 is a second embodiment of the present Invention shown.
- a fixed device 18 as already detailed was arranged between the press stands of the press.
- the movable device can then on a relative to the fixed device 18th Movable machine part can be arranged, which also with respect to the stationary device 18 performs a linear movement.
- the fixed device 18 is advantageously transverse to at least one arranged to the transfer direction traverse on the forming machine.
- FIG. 5 only as an example the fixed device 18, for example on a crossbar or the Press stand can be arranged while on a transfer rail 26 to the stationary device 18 complementary movable device 22 (not here visible) is attached.
