Definitions

  • the invention relates to a sensor arrangement for detecting the movement of a wire core in a welding system, through which wire core a welding wire is guided between two wire feed devices, with a sensor surrounding the welding wire, with a housing and an evaluation element.
  • the invention relates to a welding system with a welding device, a hose package and a welding torch, the hose package connecting the welding torch to the welding device, wherein between two wire feed devices, a device designed as a wire buffer memory for buffering a welding wire guided within a wire core, and also a sensor is arranged for contactless measurement of the movement of the wire core.
  • the welding device is usually connected to the welding torch via a hose package in which all lines, such as a power line, cooling lines for a liquid-cooled welding torch and one or more control lines, are arranged.
  • the welding wire required for a welding process is transported from the welding device or a wire feed device to the welding torch by inserting it into a wire core.
  • the wire core is inserted into a wire guide tube which is preferably arranged in the tube package.
  • the wire core is preferably fixed at both ends, as a result of which no longitudinal movement of the wire core is carried out.
  • the wire core is only freely movable at one end with special wire feed.
  • the wire core is exposed in the area of the welding device or a wire feed device and runs without a guide before it flows into the hose package.
  • such an arrangement of the wire core for welding wire conveying with different speeds or conveying directions that is, a forward / backward Movement of the welding wire, as known for example from DE 197 38 785 C2 or DE 43 20 405 C2, is used, with the exposed part of the wire core forming a type of wire buffer memory.
  • a transport device is known from DE 38 27 508 AI, in which a welding wire is conveyed with constant force even under unfavorable forces and thus tensile or compressive stresses are avoided.
  • the welding wire is between a pushing wire feed device, which is arranged in the welding device or in a wire feed device, and a pulling wire feed device, which is preferably arranged in the area of the welding torch or in the welding torch itself, through an evasive part and a curved hose, in particular the wire core, guided.
  • the hose tension i.e. the exposed part of the wire core, is supported by a spring.
  • the evasive part is coupled to a control element which measures the evasive path of the evasive part when pressure or tensile stresses occur on the welding wire and feeds it to a controller for compensation via a speed control of the first drive.
  • the welding wire is unwound from the supply drum via the first wire feed device and inserted into a hose or a wire core.
  • the wire core is then arranged exposed and forms a wire buffer memory in the form of a loop in this exposed area, the loop being able to deform in this exposed area, ie the loop is enlarged or reduced.
  • the wire core is then inserted into the hose package and extends over the wire guide hose, which is only insignificantly larger than the outer diameter of the wire core, until further wire feed.
  • SU 1 489 941 A shows a sensor for detecting the capacity of a wire buffer memory formed by a loop of the wire core, in which the wire core is arranged between two electrically conductive surfaces. By shifting the wire core, a special shape of the surface causes a change in resistance from which the position of the wire core within the sensor and thus the capacity of the wire buffer memory can be deduced.
  • the disadvantage here is that the wire core grinds between the surfaces of the sensor and thus a force-free displacement of the wire core is not possible, which has an adverse effect on the sensitivity of the sensor but also has an adverse effect on the wire feed. Furthermore, the sensor is subject to greater wear due to the contact of the wire core. Finally, such a sensor, which extends essentially over the entire loop of the wire core, is relatively voluminous.
  • a wire feed device with a longitudinal compensation device is described in AT 394 675 B, wherein a sensor detects the longitudinal movement of the hose package and emits an actual value signal to a controller.
  • the disadvantage here is that the longitudinal movement of the hose package takes place by means of a plunger anchor attached to a movable sliding part.
  • Another disadvantage of this design of a sensor is the size and relatively large moving masses, which makes a force-free displacement of the wire core in the sensor impossible. This also reduces the sensitivity of the sensor.
  • the object of the present invention is therefore to create a sensor arrangement for detecting the movement of a wire core in a welding system and a welding system of the type in question, in which a very simple and compact design of the sensor is created. Another task is that the detection of the longitudinal movement of the wire core is carried out without contact, so that as little interference as possible acts on the wire core in the form of friction and thus a very good measurement result is achieved.
  • the objects according to the invention are achieved in that an indicator is provided which is formed by the wire core or is connected to the wire core, which indicator can be displaced force-free in the longitudinal direction in the sensor and that the evaluation element is arranged in the housing.
  • the closed structural unit greatly reduces or prevents the ingress of dirt from the outside, so that the service life can be increased.
  • a very long measuring length can be achieved, since the housing of the sensor can be adapted accordingly to the expected changes in length. It is also possible to make the size of the sensor very small, so that it can be arranged directly in a welding torch or a hose package.
  • Another major advantage is that a simple exchange of the wire core is possible without first loosening a rigid connection, thereby reducing the service life of the welding system during which no welding can take place. Due to the indicator, which can be displaced force-free in the longitudinal direction, no friction losses occur in the sensor, as a result of which the movement of the wire core is not influenced by the sensor.
  • the sensor is advantageously arranged in front of a wire feed device and preferably after a wire buffer store located between the wire feed devices, so that the fill level or the storage volume of the wire buffer store can be detected via the longitudinal movement of the wire core. This enables the wire core movement to be monitored in a simple and inexpensive manner.
  • the sensor is advantageously arranged directly in front of the wire feed device or immediately after the wire buffer memory.
  • the position of the sensor can be determined exactly.
  • the sensor is advantageously connected to a wire feed device, so that the wire feed can be regulated in accordance with the fill level or storage volume of the wire buffer store.
  • the senor can be arranged in a welding torch, in particular in a torch handle or in a hose package.
  • the size or shape of the welding torch or the hose package is not changed by the arrangement of the sensor.
  • the indicator can be fixed or detachably connected to the wire core.
  • the sensor can be arranged at any point on the wire core.
  • the indicator forms the end of the wire core and the wire core ends with the final indicator in the sensor.
