Definitions
- the invention relates to a pneumatic assembly for multi-axis positioning of a Machine element, with a stationary installed first pneumatic drive, at the movable part a second pneumatic drive is attached, which in between arranged drive means for supplying the second pneumatic drive with energy is operable.
- the field of application of such a pneumatic assembly extends primarily to the handling technique.
- machine elements such as grippers for Material flow operations or tools for machining a workpiece along a movement axis (linear movement) or around a movement axis (Rotational movement) transported from a starting point to at least one destination.
- One Another field of application of the invention is printing press technology.
- an assembly for a printing machine with a wireless is Energy transfer between two relatively movable machine parts.
- Both electrical supply energy and data for driving are from a fixed machine part on a rotating machine part of a printing press transfer.
- a stationary control unit is provided, which with a Processing unit cooperates, which at least one electrical load in Form of a servomotor applied, which is responsible for the transmission of electrical energy and the data is a stationary transformer in the form of a two-part transformer is provided, the other part rotating on the rotating machine component is arranged. Both parts of the transformer are inductively connected to each other via the primary or secondary developments coupled.
- the stationary transformer as a AC voltage supplied electrical energy contactless arranged a rotating Rectifier supply as well as the data pulses supplied as data contactless one also supply rotating signal drivers.
- the energy transfer takes place here preferably in pulses between their death times the data transfer takes place.
- the Energy and data transmission can alternatively also together in the form of a modulated AC voltage can be performed.
- the invention includes the technical teaching that drive means for supplying the second pneumatic power drive comprising a fixed first charging station, the with a second mobile attached to the second pneumatic drive Charging station for the wireless transmission of electrical energy in the range of at least one End position of the first pneumatic drive cooperates to over this the electrical Supply voltage also arranged on the part of the second pneumatic drive Electropneumatic valve for pneumatic control of the second drive provide.
- the wireless transmission of the electrical supply voltage after the Transformer principle wherein the first charging station, a primary coil and the second Charging station forms a secondary coil.
- the electrical supply voltage to the second pneumatic drive are transmitted while it is in the range of an end position of the first pneumatic drive is located, in which a local proximity to the first charging station consists. The closer this comes to the second charging station of the first charging station, the more electrical energy can be transmitted wirelessly.
- the wireless power transmission even performed on a leg of the stroke of the first pneumatic drive unit become.
- other conventional electric wireless To use energy transfer devices for the purpose of the invention such as for example, an RF energy transmission.
- the second charging station is followed by an accumulator to the wireless transmit transmitted supply voltage herein. This measure will despite discontinuous transmission of the supply voltage as a result of the reciprocation of the first pneumatic drive ensures a uniform power supply.
- the Compressed air supply to the valve via a flexible - preferably spiral - Hose line which is a connection between a stationary supply pressure wave and a supply pressure port on the valve of the second pneumatic actuator manufactures.
- the transmission of electrical control signals (data) to the electropneumatic valve of the second pneumatic drive is preferably via a thereto arranged Signal transmission unit by radio via antenna from a remote control unit, the insofar as a sender acts. But it is also conceivable that the transmission of electrical Control signals via other wireless technical means - such as infrared or Ultrasound or the like - takes place.
- the discontinuous movements of the first Although driving the pneumatic assembly allow wireless transmission of a Supply voltage (which can then be sufficiently buffered); however, can be over this Transmission line not transmit the electrical drive signals. Because it is not permissible that the second drive temporarily not controllable, that is addressable.
- the Transmission of electrical control signals via the separate wireless channel overcomes this disadvantage.
- the first pneumatic drive and / or the second pneumatic drive can both as Linear drive and be designed as a rotary drive.
- a linear drive leads a back and forth Hermos by, whereas the rotary drive in the context of this invention a Angle adjustment allows.
- the first pneumatic drive preferably designed in the manner of a rodless cylinder be, whose carriage forms the movable part, where the second pneumatic drive is arranged.
- This is preferably in the manner of a normal pneumatic cylinder formed at the distal end of the piston rod to be positioned Machine element is arranged.
- the figure shows a schematic representation of a pneumatic assembly with wireless Power supply.
- the pneumatic assembly according to FIG essentially consists of a first pneumatic drive 1 with a cylinder housing 2, in which a - not here shown - piston is housed axially movable and via compressed air connections. 4 can be acted upon on both sides.
- a coupled to the piston carriage 3 passes the Movement of the integrated piston continues to the outside and serves to accommodate adjacent Components.
- a work unit essentially consisting of a second pneumatic drive 5, the type of a normal Pneumatic cylinder is formed. Its piston rod 6 carries the position to be positioned Machine element 7.
- the second pneumatic drive 5 is from a cylinder bottom side arranged valve 8 is acted upon on both sides with pressure medium.
- the valve 8 is in this Embodiment designed in the manner of an electropneumatic 5/2-way valve.
- the electrical control of the valve 8 takes place from an adjacent thereto electronic signal transmission unit 9.
- the signal transmission unit 9 receives the electrical control signals for the valve 8 by radio via an antenna 10.
- the Signal transmission unit 9 is both as a receiver of drive signals for the valve. 8 provided by the - not shown - higher-level control unit from; Farther the signal transmission unit 9 also serves as a transmitter of detected operating parameters of the second pneumatic drive 5.
- the current operating position of the second pneumatic actuator 5, which are detected by sensors 11a and 11b and the electronic Signal transmission unit 9 are supplied on the input side, which these via the antenna 10 wirelessly to the remote control unit for control signal processing forwards.
- a flexible hose 12 For compressed air supply to the valve 8, a flexible hose 12 is provided.
- the spirally wound flexible hose 12 provides a compressed air connection between a stationary feed pressure source 13 and a feed pressure port to valve 8 of the second pneumatic drive 5 forth.
- the supply of the electro-pneumatic valve 8 and the electronic Signal transmission unit 9 with the required supply voltage is carried out by a electric accumulator 14 off.
- the accumulator 14 is charged via a Transformer arrangement consisting of one adjacent to the accumulator 14 and thus with the carriage 3 of the first pneumatic drive 1 movable second charging station 15b, which cooperates wirelessly with a stationarily arranged first charging station 15a.
- the wireless transmission of electrical energy occurs in the pneumatic assembly in Area of the end position of the first pneumatic drive 1 shown in the figure, in which is the first charging station 15a in local proximity to the second charging station 15b.
