Definitions

  • the invention relates to a method for operating a bale opener and to a bale opener according to the independent claims.
  • Abtragorgane be used in so-called Ballenabtragmaschinen or Baleöffnern to solve fibers or fibrils of pressed fiber bales out.
  • the removal organ is moved across the fiber bales.
  • the bale stripping machine is at the beginning of processing lines in a spinning mill preparation (processing) for the processing of fiber material, such as cotton or synthetic fibers or mixtures thereof, and has a decisive influence on the continuity of the processes within the spinning mill preparation.
  • the fiber material delivered in bales is removed from the bales by removing fiber flakes and transferred to a pneumatic transport system.
  • the pneumatic transport system brings the fiber flakes through pipes to the following cleaning machines.
  • the Abtragorgan is attached to a movable Abtragturm height adjustable.
  • the removal member comprises one or more removal rollers with teeth mounted on its surface, a retaining element mounted below the removal roller and a suction hood.
  • the teeth engage in the fiber bales and tear or pluck due to the rotation of the discharge roller fibers respectively fiber flakes out of the fiber bale out.
  • the torn-out fiber flakes are taken over by the suction hood connected to a vacuum source from the removal roller and fed to the transport system.
  • DE4422574A1 discloses, for example, a method for removing fiber flakes from textile fiber bales (eg cotton) by means of a down to the fiber bales and on the ball reciprocating Abtragorgans, which dissolves the fiber flakes from the bale surface and a flock transport, the ball height divided into at least three Abtragzonen is.
  • the driving speed of the car with the Abtrageorgan is changed depending on the bale height.
  • the invention is therefore based on the object to provide a method and a bale opener, which improve the communication between the bale opener and the subsequent storage machine.
  • Another object of the invention is to provide a method and a bale opener which provides an optimal production value per storage machine.
  • the invention is further based on the object to provide a method and a bale opener, which ensures an ideal capacity of the storage machines.
  • an erosion value could be determined, which is calculated from an erosion depth and a longitudinal section. This is advantageously calculated for a storage machine, in which ratio a newly established group of bales is to be removed to the remaining groups of bales and it is decided which group of bales deviates most from the percentage Abtragungswert to then remove them. It is also conceivable to calculate for a storage machine which bale group differs most from the percentage ablation value according to settings and this group of bales is removed.
  • bale group of an associated storage machine can then preferably be removed. Thereafter, again ensures an ideal capacity of the storage machines.
  • bale groups which are obvious to the removal organ may nevertheless be preferred within the scope of the invention.
  • the user can specify a driving speed within which a desired production value is to be kept constant. It could also be the Abtragtiefe be regulated if a maximum or minimum of the set travel speed is reached.
  • the invention also relates to a computer program product which can be loaded directly into an internal memory of a bale opener according to the invention and comprises software code sections with which the method steps of the method according to the invention are carried out when the product is running on the bale opener.
  • FIG. 1 1 shows a bale opener 1 according to the invention.
  • the bale opener 1 consists essentially of an ablation tower 2 and an ablation member 3.
  • the ablation member 3 is fastened on the ablation tower 2 on one side and arranged cantilevered over fiber bales 4.
  • the Abtragturm 2 is equipped with a chassis 5. With the help of the chassis 5, the ablation tower 2 is moved on rails 6 along the fiber bale 4. As a result of this movement, the removal member 3 attached to the removal tower 2 is guided over the surface of the fiber bales 2 below it.
  • the attachment of the Abtragorgans 3 on the ablation tower 2 is made adjustable in height, so that the fiber bales 4 can be removed continuously.
  • a removal roller 7 is arranged with an axis 8.
  • the removal roller 7 takes from the fiber bale 4 fiber flakes.
  • the fiber flakes are removed via a suction hood 9 by means of negative pressure from the removal roller 7 and guided to the removal tower 2.
  • a transport channel 10 is arranged, which takes over the fiber flakes of the suction hood 9 and a pneumatic fiber flake transport system 11 feeds.
  • the transport channel 10 and thus also the suction hood 9 are under a certain negative pressure, which serves for the pneumatic conveying of the fiber flakes to the transport channel 10.
  • Fig. 2 schematically shows the inventive communication between the bale opener 1 and a plurality of associated storage machines 12 1 , 12 2 , 12 third
  • the bale opener 1 is connected to the storage machines 12 via the transport system 11.
  • a controller 13 with an internal memory 14 is connected via a control line 15 to the machines.
  • a bale opener 1 supplies several storage machines 12 1 , 12 2 , 12 3 (multi-range operation), wherein the transport system 11 is correspondingly adjustable.
  • the invention now receives the bale opener 1 via the controller 13 information from the storage machines 12 1 , 12 2 , 12 3 , which material they require.
  • the required material is removed by a group of bales 4, so that the bale opener 1 associated storage machines 12 1 , 12 2 , 12 3rd are ideally filled and at the same time no bale group is unnecessarily run over unproductive.
  • a storage machine 12 1 , 12 2 , 12 3 which requires material is therefore preferred, ie the bale groups 4 of the preferred storage machine are preferably removed.
  • the controller 13 reacts, so that thereafter the other storage machine 12 1 , 12 2 , 12 3 are alternately removed and filled again.
  • bale opener 1 thus advantageously provides per storage machine 12 1 , 12 2 , 12 3 / assortment an ideal production height, so that the associated storage machine 12 1 , 12 2 , 12 3 is ideally filled.
  • the ablated elongated cross-sectional area is determined as the ablation value for each group of bales 4.
  • the controller 13 is now set in which percentage ratio a newly established bale group 4 of the associated storage machine 12 1 , 12 2 , 12 3 are to be removed to the other remaining bale groups 4. If it is now decided which bundle group 4 of the same storage machine 12 1 , 12 2 , 12 3 is to be removed next, it is calculated which bundle group 4 of this associated storage machine 12 1 , 12 2 , 12 3 deviates most from the percentage removal value according to the setting. This bale group 4 is then removed.
  • the highest priority in the decision-making process is always that no bale group 4 should be unnecessarily run over unproductively, ie in the decision process, the nearby bale groups 4 are preferred, even if one of these bale group 4 is not the first choice with regard to production prioritization.
  • a production value is now set by the user via a bale group 4, so that the controller 13 attempts to produce according to the setpoint to keep constant.
  • a storage machine 12 1 , 12 2 , 12 3 is calculated how much percent of the time material is required. This is set by the customer.
  • a regulation algorithm now calculates the optimal production value per assortment so that the corresponding storage machine 12 1 , 12 2 , 12 3 are ideally filled.
  • the removal speed could advantageously be taken as the manipulated variable, ie the user specifies a driving speed range within which the controller 13 attempts to keep the production setpoint constant. If the maximum or minimum of the set driving speed is reached, only then is the cutting depth automatically adjusted and regulated.
  • the invention also relates to a computer program product which can be loaded directly into the internal memory 14 of a bale opener 1 and comprises software code sections with which the method steps of the method according to the invention are carried out when the product is running on the bale opener.
