Definitions

  • the invention relates to a method and a device for separating and Removing uncooled and non-tolerant wire windings from the beginning and end one over a Stelmor plant or a comparable wire winding transport system transported roll core, a number of front Number of turns of the rolling wire and according to a predetermined number from turns, these are separated from the finished wire as front crimp turns the cut front crimp turns when passing an open one Switch at the end of the first transport route from the level of the Stelmor facility or a comparable wire winding transport system is deflected downwards and transported away, whereas finished wire after closing the switch in the Stelmor plant is transported on.
  • the range of dimensions of modern wire rod products ranges from wire diameters from 5.0 to 25 mm with a range of finish rolling speeds between 120 and approx. 20 m / s.
  • To set the required structural properties are Stelmor speeds when cooling between 0.1 m / s and approx. 1.2 m / s required. According to the final rolling speed depending on the diameter this results in different laying densities on the Stelmor transport or comparable wire winding transport systems between 25 and 300 turns per meter.
  • a first roller conveyor is one Downstream shaft with tentacles arranged in which the wire turns to be cropped be separated with scissors.
  • the control of the scissors and The falling of the tentacles into the crest shaft is carried out by a process control computer with image recognition computer, which with one above the roller conveyor arranged opto-electronic sensor is connected.
  • a second roller conveyor which is movable via a hydraulic cylinder is arranged, that can be tilted out of the transport direction and those to be removed Conveys wire turns downwards out of the wire turn strand.
  • the invention is based on the object, starting from the aforementioned state state of the art to specify a method and a device with the aid of which required manual work when cutting uncooled and non-tolerant Wire windings from the beginning and end of one over a Stelmor system or comparable wire winding transport systems Rolling wire through an even more reliable mechanization or automation can be replaced to create more humane working conditions and more economical Create processes.
  • a number of front turns of the rolling core are counted and according to a given number of turns, these are called the front cropping separated from the finished wire.
  • the separated ones Coils accelerate on a first transport route and the following finished wire delayed and thus broadened the interface in transport.
  • the separated front crimp turns when passing one initially open switch at the end of the first transport route from the level of the Stelmor facility or a comparable wire winding transport system downwards distracted and transported away, whereas finished wire after closing the switch in the Stelmor system and the separated and transported away Windings collected under the Stelmor system on a cathedral as mini bundles or chopped shears and chopped up.
  • the invention is based proceeded similarly.
  • the rear end of the roller core is monitored and after reaching a predetermined remaining length from the roll core severed as a crotch, and the rest of the finished wire separated from the crest accelerated in transport, at the same time the separated crimp turns delayed on the first transport route and thus the interface widened, and finally the separated crescent turns at Enter the open switch at the end of the first transport route from the plain the Stelmor plant or a comparable one Wire winding transport system deflected down and transported away, under the Stelmor plant or one comparable wire winding transport system and divided.
  • the process according to the invention is of great advantage the separation of uncooled and non-tolerant Wire turns from the collar on the hook of the hook track into the Transport area of the Stelmor plant relocated or one comparable wire winding transport system. This eliminates the previously required human resources, which at the same time significantly improves the economics of the process becomes.
  • the measure can preferably be used, that from the front or back crotch turns Pass the switch below the Stelmor system or one comparable wire winding transport system mini bundles for example, formed on a mandrel and this removed and collected for further processing become.
  • An embodiment of the method provides that the as Soft trained first transport route to open from the Level of a Stelmor plant or a comparable one Wire winding transport system can be folded down and down can be folded up into the transport level for closing or that the following segment can be opened from the Transport level folded diagonally upwards and to close in the transport level is folded down.
  • an embodiment of the invention provides that the Switch for removing front crimp turns at Separation cut opened and immediately before the arrival of the Interface closed at the end of the first transport route is, the finished wire after disconnection and removal of the Front head over the SteLmor plant or one comparable wire winding transport system transported becomes.
  • the method according to the invention provides that cutting off the crescent crimp at that moment is made in which the optical or magnetic monitored rear end of the rolling wire a predetermined Position, for example, in the area of the wire finishing block has reached.
