Definitions

  • the invention relates to a device for separating rod-shaped or tubular material with at least one transporting device for speeding up the material to be separated and at least one transporting device for retarding the material to be separated, and a processing device comprising such a separating device.
  • the invention relates to a method for separating rod-like or tubular material, in which the material is first accelerated and then delayed, and a method for processing rod or tube-like material, wherein the material cut to length after at least a first processing and provided after cutting to a second processing and this is separated accordingly.
  • such a device is a production line for producing a metal tube in which the metal tube is unwound from a coil, then pulled through a die and then straightened, with the drawn and straightened metal tube subsequently cut to length and behind Cutting device with high speed for further processing is removed transversely.
  • the machining processes are constantly being improved and thus accelerated by further developments in plant construction, it is particularly important to remove the cut pipe lengths from the cutting device as quickly as possible.
  • the individual tube lengths are accelerated by roller pairs of a roller apparatus by means of a mechanical contact and decelerated again at a suitable point, so that the tube lengths can then either be further processed or simply stored.
  • the object of the invention is achieved on the one hand by a device for separating rod-like or tubular material with at least one transport device for speeding up the material to be separated and at least one transport device for decelerating the material to be separated, wherein at least one of the two transport devices means for non-contact Accelerating the material has.
  • acceleration includes both an increase in speed, that is, a speeding-up, and a lowering of the speed, that is, a deceleration of the accelerated one Material.
  • a speeding-acting transport device is hereinafter referred to as Verschnellungs Skewed and a braking or retarding acting transport device hereinafter referred to as a delay device, while an acceleration device as a generic term includes both Verschnellungs- and delay devices.
  • the means for non-contact acceleration allow much higher speeds in the further transport of the cut-to-length material, since the means for non-contact acceleration continue to work evenly independent of external influencing factors. For example, with conventional contacting transport devices, a further significant increase in speed in the further transport of cut to length material due to different material geometries and / or residues of processing agents on the material surface can not be achieved.
  • the object of the invention is achieved by a method for separating rod-like or tubular material, in which the material first accelerates and is subsequently decelerated, wherein the material accelerates and / or decelerates without contact.
  • a mechanical contact between the material to be conveyed and means for accelerating of the material such as transport rollers of a transport device dispensed.
  • the above-described devices or methods are particularly advantageous when the rod or tube-like material has a longitudinal direction and the two transport devices accelerate the rod or tube-like material parallel to the longitudinal direction. Even if the deceleration device is followed by a transverse transport, which moves the rod-like or tube-like material with a component perpendicular to its longitudinal direction, these devices or methods can be used particularly suitably. Especially with such Arrangements, it is difficult to realize a reliable separation even at high throughput speeds.
  • the present separating device can be used when the processing device has a modern drawing machine, by means of which the material is provided at high speed has.
  • the processing device has a cutting device, since, in particular, cut-to-length material can advantageously be separated by means of the cutting device.
  • the material is at a speed of more than 350 m / s, preferably to a speed of more than 450 m / s, is accelerated.
  • the non-contact acceleration or guiding of the material lengths is particularly advantageous because such Speed at friction and / or non-positively working transport devices can not be achieved or at least only very unsafe operation.
  • non-contact delay means can advantageously the material after accelerating to a braking speed of less than 150 m / s, preferably to a braking speed of less than 100 m / s, delayed.
  • Fast onward transport is ensured, in particular, if the braking speed is reached in less than 0.5 s, preferably less than 0.2 s.
  • the present invention makes it possible, in particular, to apply significant accelerations to the material so that the speed differences can be traversed within the shortest possible time and over the shortest possible distance. In this case, damage to the material is kept to a minimum, since the material does not have to be acted on directly mechanically to transfer the forces.
  • the means for non-contact acceleration and non-contact deceleration are structurally particularly provided when the transport device has at least two induction coils.
  • a device with such induction coils for the contactless transporting of wire or powder is known for example from the published patent application DE 19 59 873 A1, in which this device comprises three successively arranged coils according to a preferred embodiment, through the windings of the wire is moved forward. Namely, by means of a current flow, which is sent in each case by the conductor of the corresponding coil, around the coil conductor each generates a magnetic field. As a result, an eddy current is generated in the wire, whereby the wire is magnetized into a kind of "bar magnet". Now, when current is passed through an adjacent coil, the magnetized wire is attracted to the magnetic field of the adjacent coil. By suitable interconnection of the individual coils to each other, it is possible to accelerate the wire and thus move forward.
  • the induction coils can be supplied with power in a wide variety of ways.
  • this may be provided by frequency variable three phase current in sinusoidal waveform, by pulse width and / or amplitude variable DC which is at least biphasic, and / or by windings connected in series and in parallel, and by 3 phase windings which are both in Star as well as in a triangular form can be achieved.
  • the coil arrangement can, for example, be wound annularly onto coil cores or consist of air-wound, vacuum-bonded coils.
  • the guidance of the magnetic flux in the induction coil circuit can be produced on the one hand from laminated iron and on the other hand from highly permeable sintered material in the required form.
  • sintered material it is possible to make the tooth necks widened in the vicinity of the inner diameter of the coils in order to reduce the flux density at these locations and thereby prevent magnetic saturation.
  • Mechanical protection of the induction coils can be achieved either by a tubular plastic lining of the space between the material to be transported and the coil assembly or by a lining of the same kind of ceramic material.
  • mechanical guidance of the material can be provided in front of and / or behind the coils.
  • the production line 1 from FIG. 1 comprises a coil 2 on which a copper tube 3 is wound up.
  • the copper pipe 3 is transported along a processing line 4 through the production line 1.
  • a pulling device 5 is arranged, at which a straightening device 6 is connected. If the copper tube 3 is pulled and directed, it is cut to length by means of a cutting device 7 and led away by means of a transporting and separating device 8 by a cutting device 7 and provided for further processing 9.
  • the cut copper tubes are stored in a storage device 10, sawed in a sawing device 11 and bundled by means of a bundling device 12.
  • the separating device 8 shown in FIG. 2 essentially comprises a first magnetic drive 13 and a second magnetic drive 14, which are arranged one behind the other along the processing path 4.
  • the cutting device 7 in this case comprises a cutting blade 15, behind which a conventional roller drive 16 and a fishing ejection device 17 are provided. By means of the roller drive 16, the tang is withdrawn from the copper tube 3.
  • the transport device 108 shown in detail in FIG. 3, which may be used as the magnetic drive 13 or 14, has a first magnetic coil 113, a second magnetic coil 114 and a third magnetic coil 130 whose functions are controlled by an electrical control unit 131 are controlled.
  • the magnetic coil 113 is connected to the control unit 131 by means of an electrical line pair 132
  • the magnetic coil 114 is connected by means of an electrical line pair 133
  • the magnetic coil 130 is connected by means of an electrical line pair 134.
  • the magnetic coils 113, 114 and 130 are each supplied with power.
  • the copper tube 135 moves according to arrow 136 through the magnetic coils 113, 114 and 130 forward.
  • the direction of the arrow corresponds to the main direction of movement and the longitudinal extent direction of the copper tube.
  • the magnetic coils 113, 114 and 130 enclose here the copper tube 135 and are traversed by either a direct current or an alternating current.
  • the current can be varied as needed in its intensity, direction and / or frequency.
  • the forward movement takes place in that the current-carrying coil 113 passes through the copper tube 135 with a magnetic field 137.
  • a magnetic field (not shown explicitly for clarity) is also induced in the copper tube 135 itself by eddy currents, which is initially substantially equal in magnitude and direction to the original magnetic field 137 is.
  • the resulting magnetic field 138 of the second coil 114 interacts with the previously induced magnetic field of the first coil 113, so that a corresponding force gradient 139 is produced in the direction of the arrow 136.
  • the direction of the force gradient 139 can be reversed by using a 3-phase rotary current by reversing the rotary field direction.
  • the copper tube 135 can either be accelerated or decelerated.
  • the magnetic fields 137, 138 and 140 can by a suitable choice of the magnetic coils 113, 114 and 130 homogeneous or inhomogeneous magnetic fields, ie with respect to a magnetic coil width an increasing or decreasing magnetic field, generate.
  • a suitable interconnection of the magnetic coils 113, 114 and 130 to each other along the direction of the arrow 136 a traveling magnetic field can be generated.
  • the speeds required for the purpose of separating and depositing workpieces, such as the copper tube 135 can be set manually in at least two or more stages by an operator of the transport device 108 or depending on workpiece diameters and / or workpiece lengths program-controlled or preset values previously stored.
