Definitions

  • the invention relates to a device for cutting a conduit according to the preamble of claim 1.
  • the invention further relates to a method for cutting an empty tube according to the preamble of claim 12.
  • the invention also relates to a computer program product.
  • Methods and apparatus for cutting conduits are used in practice to cut conduits of any kind into individual conduits of defined length.
  • the empty tube is usually unwound from a roll and fed to the corresponding device as a blank of a somewhat "infinite" length. It depends on the accuracy of the cut and for economic reasons also on the speed or throughput of the device.
  • the empty tube is first positioned axially by means of a feed wheel on a cutting device and then severed from this at a cutting position. It has been shown that an exact positioning of the empty tube on the cutting device or ensuring an exact cutting position for many applications, in particular while maintaining a high throughput, with the conventional devices is possible only with considerable effort.
  • the present invention is therefore based on the object to provide an apparatus and a method for cutting an empty tube, wherein the disadvantages of the prior art are avoided and in particular a sufficiently accurate axial positioning of the empty tube is made possible on the cutting device.
  • the device according to the invention for cutting an empty tube comprises a cutting device for cutting and / or cutting the empty tube at an axial cutting position, at least one feed wheel for the axial positioning of the empty tube at the cutting device, and a control device.
  • this can be a rigid or flexible pipe, preferably of plastic or metal.
  • Such conduits for example, for the installation of other pipes, z.
  • the conduit according to the invention can also be suitable for the direct transport of solids, liquids and / or gases. On the subsequent use of the empty pipe it does not matter in the context of the invention.
  • one of the at least one feed wheel along the empty tube axially spaced measuring wheel is provided to detect an axial feed length of the empty tube. Furthermore, an additional sensor device is provided to detect an axial position of the empty tube relative to the cutting device. The control device is set up to use the empty tube on the basis of measured data of the measuring wheel and measured data of the sensor device by driving the at least one feed wheel into the cutting position.
  • the axial infeed length of the empty tube which is detected by means of the measuring wheel, corresponds essentially to the length of the individual cut-length empty tube pieces resulting from a cutting of the empty tube.
  • the axial position of the empty tube relative to the cutting device may, for example, be an axial position of a partial section that repeats axially along the empty tube.
  • the actual cutting position can be based on the measurement data of the measuring wheel and the sensor device.
  • the inventive use of a measuring wheel in combination with the additional sensor device allows extremely accurate positioning of the empty tube on the cutting device.
  • an absolute position or an axial feed length which can be determined by means of the measuring wheel, is combined with a relative position of the empty tube (or a section of the empty tube). This can ensure that a predetermined length of the cut or cut empty pipe sections and / or a predetermined distance between slots or perforations of the empty pipe are maintained, at the same time an exact alignment of relative reference points or sections of the empty pipe lead to an optimal cutting result on the cutting device.
  • the empty tube is designed as a corrugated tube and / or corrugated tube.
  • the cutting of corrugated pipes and corrugated hoses is particularly complex due to their wavy outer structure, which is why the invention can be particularly suitable for the exact cutting of corrugated pipes and / or corrugated hoses.

  • the improvement according to the invention regarding the positioning of the empty tube on the cutting device can basically have a positive effect on all types of cutting device.
  • the cutting device is designed to cut the empty tube orthogonal to an axial feed direction at the cutting position and / or cutting, z. B. at least partially perforate along the circumference of the empty tube.
