Definitions

  • the invention relates to an apparatus and a method for Cutting a continuous wire that is in Form of coils emerges from a coiler.
  • Wire is usually made by rolling and drawing. After the rolling, the wire passes through a winding layer, and the wire windings are then used to cool down Laying roller conveyor and a winding conveyor belt promoted to via an infeed roller table in a bundle chamber below Use of a mandrel to form a bundle become. The wire bundle is then picked up with a hook.
  • the initial turns are rejected. reason this is a different cooling of the first turns, the one with the still cold roller tables of the Turn conveyor belt come into contact during the cool subsequent turns more evenly. In the Initial turns result in undesirable structural changes. The initial turns are therefore over after transportation cut the winding conveyor belt, i.e. at the end of the belt, in the bundle chamber or only on the hook. This does not constitute Difficulty because the initial turns on the hook on the hang open side and are therefore easily accessible.
  • the invention is based on this prior art the task is a fast and accurate device to create targeted with the wire twists can be cut off. Furthermore, a corresponding Procedures are created.
  • a cutting device is proposed that immediately is arranged behind the winding layer.
  • It includes fishing gear for the targeted grasping of a winding arc and means for severing this winding arc. It are means of controlling the movement sequence of the catch and Release agent provided. The control takes place, for example depending on the wire properties such as the wire diameter with inaccuracies. Furthermore, the Catch and release agent depending on the working position of the winding layer can be controlled.
  • the end turns, which are rejects, are used the proposed device no longer at the end of the belt, removed in the bundle chamber or only on the hook, but immediately after exiting the laying tube of a Winding layer.
  • This device shows the following advantages.
  • the wire windings have immediately behind the winding layer an even distance from each other, and the fishing gear can be moved between the individual turns, thus the reject turns from the true turns to separate.
  • the interface on the winding circumference is adjustable so that always pulling the end of the last dimensionally correct wire winding can be transported on the winding conveyor belt. This ensures undisturbed transport of the tortuous Wire over the conveyor roller tables without snagging the Final turn. This eliminates the time-consuming and unsafe process Position at the end of the wire.
  • the cut can be made perpendicular to the wire. There is no need for large cutting forces as a result of the high processing temperature of the wire.
  • the space between the two stations as well as the space below the laying roller table for disposal of the committee material can be used.
  • the catching means are made from two (catching) arms, which, viewed in the direction of the turns, are staggered. The corresponds to Offset between the two arms the pitch angle one Wire winding. These two arms thus form a kind of catch fork for a winding arc.
  • the two arms advantageously have an arc shape, which correspond to the curvature of a turn. They are from driven outside under a winding arc and thus create briefly a base for one turn and thus one calm point of attack for the release agent.
  • This release agent in the form of a pair of scissors grips the winding arch at the point that is not supported by the poor.
  • the scissors consist of an upper and a lower one Shear element together.
  • the upper shear element is like this stored that it makes a circular motion, meanwhile the lower shear element with the lower knife vibrates goes through.
  • the tentacles and scissors are regarding the start of movement Controllable end and end. This is achieved through respective Drive systems using sensors used in process plants, for example the rolling mill, in front of the winding layer or are attached to the winding layer itself become.
  • the sensors are preferably photocells. If there is an inaccuracy in the wire diameter occurs, this is recorded by the sensor and the start of movement initiated for the tentacles and scissors.
  • the drive for this swing system can be reached after the smallest distance between the two tentacles and stopped to separate and fall off to wait for the winding arches. If the cut turns but falling quickly, there is no interruption the vibration movement.
  • the shear element is also driven around a crank arm system.
  • crank arm systems are driven by everyone any motor, preferably an electric motor with a small one Moment of inertia.
  • a method is also proposed. Here will the sequence of movements and the speed of the fishing gear for a winding arc and release agent controlled so that the Catches under a certain winding shortly after swinging out of the coiler and the Release agent cut through the stabilized winding arc. This is where the catching and release agents begin to move shortly after.
  • Figure 1 shows a winding layer 1 with a laying tube 1a and Exit 1b. After processing the wire, for example in the rolling mill, this is laid in turns and in this Form (2a, b) on the laying roller table 3 to Conveyor belt (not shown) transported.
  • An upper and lower tentacles 4a, 4b are located between a winding arc.
  • the upper and lower shear element is represented schematically with 5a, 5b.
  • the tentacles 4a, 4b and the shear elements 5a, 5b are directly behind the laying tube 1a the winding layer 1 arranged.
  • the cut wire board falls over the chute 6 into a collecting container 7, with the chute 6 directly below the tentacles 4a, 4b and scissors 5a, 5b.
  • a chopper can be known Type with helical knives (not shown) be arranged.
  • the two tentacles 5a, 5b are offset from one another at a distance arranged, the distance of the slope of a Corresponding winding arc ( Figure 2).
  • the tentacles are swung into a winding arc.
  • the Shear elements 5a, 5b act on the wire, which is not supported by the tentacles 4a, 4b.
  • the speed the scissors correspond to the speed of the wire, here 3m / sec.
  • FIG. 3 shows a top view two arcuate tentacles 4a, 4b, the curvature of the corresponds to a winding arc.
  • the upper tentacle 4a with a semicircular jacket 4c so that the last turns are not thrown out.
  • a motor 8 ( Figure 4), which has a clutch 9 and a transmission 10 and a gear set 11 via a common drive shaft 12 drives two eccentric disks 13a, 13b. This are via bolts 14a, 14b with a coupling rod 15a, 15b connected, which in turn via a bolt 16a, 16b second eccentric 17a, 17b drives on the output shaft 18a, 18b is mounted. Input and output shaft are located in a common housing 18c. In the Figure 4 is the direction of rotation of the output shaft 18a, 18b shown the preferred direction for right-hand wire.
  • the tentacles 4a, 4b are welded to the Eccentric disc 17a, 17b attached.
  • the first forms Eccentric disc 13a, 13b with the corresponding catch arm 4a, 4b one unit. Overall, it is a crank arm drive.
  • FIG. 3 An embodiment of the drive of the shear element shows FIG. 3.
  • the upper shear element 5a has an upper knife 19a
  • the lower shear element 5b has a lower knife 19b.
  • As a drive system a crank arm system is also provided.
  • the upper element runs in a circular motion. It has an acceleration and deceleration angle of approx. 270 °.
  • the scissors are driven by a motor 20 via the Couplings 21 and 22 and the transmission 23.
  • This drives a shaft 24 with an eccentric 25 as a crank connected is.
  • the eccentric 25 On the eccentric 25 is the upper knife 19a attached, which undergoes a circular movement (see also Figure 4).
  • the lower knife 19b is on a coupling rod 26 attached. This is via the second shaft 27, which in one common housing 28 is mounted with the shaft 24 via a swing arm 29 guided.
  • the shaft 27 and the rocker 29 can be in shape an eccentric disc on the other side of the coupling rod 26, as shown in dashed lines in Figure 3 is shown.
  • a additional housing 30 necessary. This embodiment proves to be particularly useful in tight spaces advantageous.
  • the space between the tentacles on the drive side as well as between the tentacles and scissors on the The scissor side should be as low as possible so that the remaining turns when impacting the tentacles are not or are only slightly bent.
  • the speed of the upper knife corresponds approximately to the horizontal speed at the start of the cut of the wire turns so the wire is affected as little as possible by the scissors.
  • the cutting process first touches the upper knife 19a on the wire.
  • the movements of the upper and lower knife 19a, 19b and upper and lower shear elements 5a, 5b are more clearly shown in Figure 4 shown in the sectional position and the catch position.
