Definitions

  • the invention relates to a method for determining the height and length of textile fiber bale groups, which are put together for a bale show.
  • Bale milling machines are known which mill fiber bales, which are put together to form a bale display, by means of toothed opening disks.
  • the opening device is moved by means of a chassis on the bales set up in a line.
  • the bale milling machine is positioned along the travel path and the height, as is usual in other branches of industry, by means of position measuring devices and programmable logic controllers.
  • the difficulty lies in the detection of the height and length position of the bale template, which is assembled into blocks.
  • the bales do not have a uniform surface and have different color nuances.
  • DE 33 35 793 also describes averaging by means of light barriers which, by virtue of their arrangement, permit milling which is known from the tactile gratings during reading travel.
  • the scanning with light barriers and averaging is not only very complex, it also does not allow the detection of the desired material core height. Some of the bales are loosened up very flaky on their surface. These loosenings are detected as a surface by light barriers. However, the denser material core is important for milling. Through the light scanning, wrong, higher heights are entered into the computer. This leads to a greatly reduced production or to incorrect mixes in the initial phase of the milling process.
  • DE 33 35 792 describes a method in which the start and end limits of the bale rows set up are determined directly by a sensor and are assigned to the measured distance, as is known from the height measurement, in the control computer.
  • the method described can only be used if gaps are left between the individual bale boundaries. It is not possible to take the bale structure into account. The light barriers tend to become dirty and malfunction due to small flakes.
  • the object of the invention is to provide a method for determining the surface boundaries.
  • the invention serves both for detecting the height, the length and the structure of the bale, or the assembled bale blocks.
  • the detection of the bale block limitation takes place indirectly by the detection of the milled fiber flock flow.
  • the flock flow can be detected by a light barrier in the milling head or on the milling head - delivery link.
  • the flock flow can also be done indirectly by measuring the air flow in the milling head or the connecting section. If fibers are milled, air pressure and speed change in the milling head and on the connecting section. Another conceivable possibility is to measure the floc flow using capacitive sensors or a sensor plate in the air flow.
  • the measuring process is as follows: To measure the bale height, the milling device is located above the point to be measured. The milling head is not yet in contact with the surface of the bale, so that no fibers are being conveyed. If the milling head is lowered, the plucking rollers come into engagement with the bale surface and the flake flow begins. The beginning of the flocculation is determined by a method described above and communicated to the programmable logic controller. At the same time as the flocculation, the value of the incremental encoder for the height is registered in the programmable logic controller.
  • the fiber flow detection also serves to detect the length limitation of a bale block. If the milling head mills along a bale block, the flake flow remains stand. If the milling head extends beyond the end face of a bale block and there is no further block or the further bale block has a lower height, the milling drums are no longer in engagement and fibers are no longer conveyed.
  • the end of the fiber stream is detected by the sensors mentioned above and communicated to the programmable logic controller. In combination with the incremental path recording, the frontal boundary of a bale block can be recorded as a numerical value.
