Definitions
- the invention relates generally to the field of movable line guides. It affects one in particular
- Energy guiding chain for the dynamic guiding of lines, such as cables, hoses or the like, and a chain link for this.
- Cable drag chains are used to protect cables between two connection points, of which at least one can be moved or moved relative to the other.
- Energy chains typically consist of articulated and/or pivoted chain links that form a receiving space for the cables and can protect any type of flexible cable, e.g. cables for electrical power and/or signal supply or hoses for the supply of liquid or gaseous operating materials.
- Energy guiding chains are usually provided as components of industrial machines and systems for supplying movable machine or system components, for the protected routing of at least one supply line, eg between a base or a fixed point and a driver that can move relative thereto. They serve to protect the supply lines routed in them from damage due to kinking or overstressing during the process and possibly also external influences.
- Cable drag chains usually form a moving strand, a stationary strand and a deflection bend in between, which runs at half the speed of the moving strand.
- the cables also in a wide variety of designs, are usually used to supply at least one mobile external consumer (outside the energy chain) with electricity, data and/or media, usually from one or more supply sources at a typically stationary connection point.
- at least one mobile external consumer outside the energy chain
- electricity, data and/or media usually from one or more supply sources at a typically stationary connection point.
- cable drag chains have already been proposed, which have been expanded to include appropriate sensor and communication modules that intelligently
- WO 2018/115528 A1 describes examples of such monitoring systems for energy chains.
- values such as acceleration, speed, temperature and other required data can be recorded, which can be used in particular to calculate the minimum failure-free running time or to predict the service life, and transmitted wirelessly, as also in WO 2018/ 115528 A1 describe (cf. there to FIG.6A-FIG.9).
- Devices of this type require electronics to implement the desired information and communication technology and must therefore be fed electrically or supplied with power.
- a simple solution to this would be to use an additional supply line that is laid within the energy guiding chain.
- the energy supply via supply lines makes retrofitting of sensors in existing energy guiding chain systems expensive and is not possible under all circumstances, e.g. if the receiving space of the energy guiding chain is already completely filled. Furthermore, such an additional supply line would also have to be renewed when it reaches its limited service life due to wear.
- a power supply via energy storage or battery is relatively maintenance-intensive since batteries have to be replaced at regular intervals. In addition to high material and labor costs, this can lead to undesirably long downtimes of the system or machine, especially in large systems with many energy chains and multiple modules, i.e. it is impractical for applications with high availability.
- a first object of the present invention is therefore to improve the power supply of such modules and sensors in such a way that the disadvantages mentioned above are at least partially eliminated or in such a way that an uncomplicated retrofitting of existing energy guiding chain installations with information and communication technology, in particular with sensors to record parameters or states or other IoT technology (Internet of Things).
- an energy guiding chain having the features of claim 1 and also, independently thereof, by a chain link according to claim 2.
- Cable drag chains are intended to lead cables to non-stationary, moving connection points.
- a power transmission chain is thus intended to be moved at least in sections, in particular moved back and forth in alternation. The movement is typically carried out by the machine or system part to be supplied, which itself is moved depending on the application.
- the present invention is based in particular on the basic idea, which appears simple in hindsight, of utilizing mechanical energy, in particular kinetic energy, occurring as intended within the energy chain, in particular in the moving strand and/or in the deflection bend, in order to be able to supply a consumer on or in the energy chain.
- an energy converter is provided which is designed to convert mechanical energy, in particular kinetic energy of the energy guiding chain, which occurs when the energy guiding chain is moved as intended the energy chain is transferred to exploit and convert this mechanical or kinetic energy into electrical energy.
- the mechanical or kinetic energy is typically transferred from the moving part of the machine or system to be supplied to the energy guiding chain.
- the electrical energy generated in this way on or in the energy transmission chain itself can be used simply to supply the consumer provided on the energy transmission chain, depending on the application.
- This surprisingly simple This approach makes it possible to generate electrical energy independently and with as little maintenance as possible, and to secure the electrical supply.
- the energy guiding chain is thus designed or expanded to generate electrical energy itself and to feed it to one or more consumers, in particular consumers which are soz This eliminates the need to lay another supply line from one of the connection points to the consumer through the energy chain or to replace used batteries.
- the energy converter can be particularly preferably designed to convert mechanical, in particular kinetic, energy into electrical energy.
- any suitable electromechanical energy converter can be used for this purpose.
- this is not mandatory, so, for example, another converter principle can also be used in addition or as an alternative, e.g. solar cells.
- electromechanical energy converters are particularly preferred, with different principles known per se being usable on the energy chain for this purpose, e.g. rotary generators for converting rotary motion, particularly in the case of rolling roller chains, linear generators for utilizing the travel motion in the longitudinal direction, a shaking generator or vibration converter or similar so-called Energy harvesters, etc., piezoelectric converters are also conceivable.
- a individual chain link according to claim 2 be equipped according to the invention so that it has an energy converter, which is designed to provide electrical energy to supply a consumer on or in the energy chain, ie possibly also on or in another chain link, can be used.
- movable strand means the length section of the power transmission chain that is moved as intended, which depends on the travel path or the current position during the process is variable in length.
- stationary or “resting” strand means the length section of the cable drag chain in a momentary consideration, which is stationary compared to the movable strand. In principle, however, depending on the application, both ends or strands of the chain can also be moved traveling or moving transition between the strands, in which the swiveling chain links are deflected while maintaining the predetermined minimum radius to protect the cables.
- the energy guiding chain can have at least one sensor module as a consumer for implementing predictive maintenance or avoiding failures.
- the sensor module can be designed to record at least one operating parameter, such as the distance traveled up to now or the number of driving cycles, the travel speed, the temperature, etc. It is preferred that at least one sensor module is designed for wireless communication with a higher-level monitoring system, such as a cloud system or the like. Such a From the transmitted operating parameters, the monitoring system can determine or calculate an expected remaining service life of the energy chain and/or of the individual chain link in order to enable predictive or anticipatory maintenance and to optimize the use of the service life.
- a wirelessly communicating sensor module is supplied with electrical energy by the energy converter, the sensor module can be operated completely independently and maintenance-free.
- the energy converter can, in particular, with interruptions, e.g. only when the
- the invention is particularly advantageous in connection with wirelessly communicating sensor modules, since neither maintenance-prone supply lines nor batteries to be replaced are necessary and in particular the intensity of the usable mechanical or kinetic energy inherently increases with the wear of the energy chain due to movement wear. Reliability of the power supply in critical applications is then inherent.
- the energy converter is designed in the form of a rotary generator based on the principle of electromagnetic induction.
- the rotary generator is operatively connected to an assigned roller or arranged on it and can use the rotational movement or rotational energy of the roller.
- the rotary generator preferably has an induction winding that is stationary on the chain link and to which at least one excitation magnet is attached the roller interacts.
- several permanent magnets can preferably be integrated into the roller and interact with at least one induction coil attached to the side plate of the chain link.
- This solution can be implemented in a compact and robust manner and allows a relatively high energy yield.
- several permanent magnets are provided over the circumference of the impeller on this, preferably an even number with alternating pole directions in the circumferential direction and/or on the outside of the circumference.
- individually distributed magnets for example, a round magnet with different pole areas can also be used as a rotor, but distributed individual magnets save weight and can be more easily integrated into existing rollers or retrofitted.
- the rotary generator but also the excitation magnets on the side bracket and / or
- Induction coil may be provided on the impeller. It is also conceivable to use electromagnets instead of or in addition to permanent magnets, possibly also using the dynamo-electric principle.
- sensors for measuring operating parameters can also be integrated into such a rotary generator.
- the distance covered by the roller assigned to the rotary generator can be determined, for example in the form of the speed, and transmitted wirelessly to at least one processing electronic system.
- a measurement of the current previously generated by the rotary generator also provides a valuable Information, because this is directly dependent on the distance covered by the respective roller chain link and can therefore also be used to estimate the remaining service life of the energy guiding chain or its parts.
- Another embodiment of the device according to the invention - which is also suitable, for example, for self-supporting energy chains - provides for an electrical generator, in particular based on the principle of an electrical linear generator, to interact with a number of magnets distributed along the length of the chain.
- an effective conversion of kinetic energy of the energy guiding chain into electrical energy can be achieved in particular when moving through the magnets in the induction coil of the energy converter.
- the magnets can form a linear generator with the winding(s) of the energy converter.
- a number of magnets, preferably permanent magnets can be provided as a stator, e.g. Alternatively or additionally, a number of permanent magnets and/or electromagnets can be provided on a bracket arranged laterally to the energy transmission chain, such as a side wall of a guide trough.
- Energy yield several energy converter units with respective induction windings can also be distributed along the length of the chain, preferably in the area of the driver-side first third of the chain, which typically performs the longest movement strokes.
- solutions are advantageous which convert the mechanical or kinetic energy as much as possible wear-free and without contact via an induction coil, so that the energy converter itself can be operated with little or no maintenance.
- the sensor module can have at least one integrated
- each permanent magnet can be provided on every nth chain link, in particular on the transverse link or separating link of a chain link of the energy transmission chain.
- the arrangement of the permanent magnets on the outside of a transverse web facing the other strand is particularly efficient in order to minimize the distance between the permanent magnets and the induction coil and to increase the magnetic flux.
- the permanent magnets can preferably be arranged in the area of the last third of the stationary strand on the driver side, so that the energy converter crosses the permanent magnets as often as possible.
- the induction coil is preferably also attached to one or more transverse webs, preferably outside of the accommodation space for the lines, for example with a coil axis perpendicular to the longitudinal direction and parallel to the side straps.
- the energy converter can comprise a vibration energy converter or a type of shaking generator, which converts the kinetic energy of the moving strand.
- the energy converter can be attached, for example, to a moving end region of the first run on the driver side.
- the vibration energy converter can in particular be comparatively small, for example as a so-called energy harvester, and possibly also micromechanically.
- an oscillating energy converter has at least one induction coil and at least one permanent magnet as an exciter, which is mounted in a freely oscillating manner by a bearing unit.
- the bearing unit can in particular comprise at least one spring element for the resilient mounting of the permanent magnet.
- a bar magnet for example, can be mounted in a tubular guide with play as a permanent magnet.
- Oscillating energy converters can be produced by reciprocating movement of the energy transmission chain, e.g. vibration of the permanent magnet in the longitudinal direction of the
- Combinations of one are also conceivable as converters
- Mechanical drive device with a flywheel similar to a wristwatch mechanism, which drives a compact rotary generator so that electricity can be generated comparatively constantly between driving cycles.
- the centrifugal mass can in particular be mounted in such a way that it is actuated or deflected again each time the chain link pivots in the deflection curve.
- the energy converter can comprise a piezoelectric component, which is provided for generating voltage from mechanical pressure.
- the piezo component can be arranged between interacting stops of adjacent chain links.
- this can alternatively or preferably in addition to the already mentioned embodiments, such as the vibration energy converter, include a solar cell for generating electrical energy, so that electrical energy can be generated by the solar cell even when the energy supply chain is at a standstill.
- an energy converter can thus be designed in the form of a solar cell attached to a chain link of the energy transmission chain or to a sensor module.
- it can be advantageous to provide energy converters only in the form of solar cells, so that there is no conversion of kinetic energy into electrical energy. This can be an advantage, for example, in installation environments in which a particularly low weight of the energy chain is required, so that a kinetic energy converter would be disadvantageous due to its own weight caused by permanent magnets and other electromechanical components and if, for example, in applications in which no magnetic elements may be used, so that the use of an induction generator is not possible.
- a further advantageous embodiment of the device according to the invention can be an electrical energy storage unit, in particular an accumulator or a capacitor store, in order to store electricity that is discontinuously generated by the energy converter for the required supply of the or a consumer.
