Definitions

  • the present invention relates to a spinning preparation device with a Mixer for mixing fibers and with a removal device for removal the fibers from the mixer and a separating device for separating Foreign substances from the fibers according to the preamble of patent claim 1.
  • the spinning preparation device is used essentially in blowroom lines for processing cotton, for spinning prepare.
  • Blowroom lines essentially consist of a bale opener, which opens the raw cotton delivered, which is then transported in the form of flakes becomes. Coarse soiling of the cotton is also eliminated.
  • the fiber flakes then come into a mixer, for example ensures that the fiber flakes are mixed through various shafts.
  • the fibers are then added to the mixer, for example, using a rising cloth removed from the mixer and transported on.
  • a separating device for separating foreign substances to arrange from the fibers.
  • the opening device consists of, for example a slow-running feed roller and an associated opening roller.
  • the of The fibers removed from the chute fall into a chute Space, the part of a separator for separating foreign substances from the fibers.
  • the disintegrated fiber flakes pass through as a kind of non-woven fabric an optical sensor system in free fall.
  • the cotton broken down into fiber flakes, not only contains natural impurities, such as dust or shell particles, but also foreign substances
  • impurities such as dust or shell particles
  • jute or cotton fabrics, cords, braids or plastics of all Type as well as contaminated fiber flakes, which are so contaminated, for example, by oil are that their further whereabouts significantly disrupt the processing of the cotton would.
  • these impurities are detected by optical means Color sensors recognized and a controlled blow-out device from the free-flowing flake stream removed.
  • DE 44 30 332 A1 discloses a separating device for separating Foreign substances known, in which pneumatically delivered in a transport shaft Fiber flakes are compressed.
  • the fibers are attached using a conveyor belt passed a wall for the optical detection of foreign substances. Through the wall. for example a glass plate, and the conveyor belt turns the fiber flakes into one Fleece shaped and in this form by the conveyor belt on the optical sensors passed the separation device.
  • the optical sensors are on the Glass wall arranged and can thus recognize the contamination.
  • the known spinning preparation devices with a separating device to remove foreign substances have the disadvantage that the fiber flakes after they were transported pneumatically - before they went into the separator arrive - have to be treated again. This is necessary to prepare them in such a way that they are of the necessary type Form can be submitted to recognize or remove the foreign substances. For example, they are compressed again and then broken down again into flakes, or they can be removed from a transport shaft and made into a non-woven fabric be shaped. The fibers are also compressed, for example, if the fibers by means of pneumatic lines from the spinning preparation device be transported to the separating device, which means the separation of transport air means.
  • the fibers are in a fiber or flake fleece that is as thin as possible is present so that foreign matter does not Good fibers can be covered and therefore not recognized. This renewed Treatments are both in construction and in energy (or air consumption) consuming.
  • the object of the present invention is therefore to make additional treatment steps possible to avoid and maintain advantageous forms of flake flow.
  • This object is achieved by designing a spinning preparation device solved according to the invention in that the separating device of the removal device is immediately downstream, the fibers from the removal device as Fiber fleece spread out transversely to the direction of fiber transport is removed and thus the Separation device are supplied, the nonwoven fabric from the separation device is examined for foreign substances and is essentially cleaned of them.
  • the inventive design of the spinning preparation device is achieved, that additional facilities can be saved that would otherwise be necessary are in order to be able to advantageously present the fibers of the separating device.
  • the favorable template form of the fibers no longer needs to be given up, if For example, the fiber flakes are present as a fleece at the end of the mixing process. Whose favorable width and thus thin training is retained. This is for detection of foreign substances is particularly advantageous.
  • Another advantage is that an additional action on the fibers can be avoided, so that a mechanical There is no strain on the fibers.
  • the Spinning preparation device can be made shorter, since an additional Device can be saved.
  • the arrangement of the separating device immediately after the removal device The mixer is particularly advantageous because the mixer is a kind of ventilation system for pneumatically conveyed fiber flakes. It is therefore not necessary, especially for that Separation device to provide a flake ventilation, which is advantageous in terms of energy technology is.
  • the fibers can be optimal because they are vented fed to the separating device as a nonwoven fabric and cleaned. Furthermore they do not have to be connected to or from the separation device via pneumatic lines be promoted. This reduces the risk of nits forming.
  • the mixer of the spinning preparation device is a shaft mixer. This ensures good mixing of the fibers, as well as a simple removal of the fibers for example by means of an advantageous riser cloth. By using a riser cloth is advantageously achieved that the fibers in the form of a fleece or Cotton can be removed from the mixer.
  • the separating device optical color sensors for Detects the contaminants because it ensures that the contaminants can be excreted without separating guff fibers become.

After the distributor 32, the shafts 31 initially extend in the vertical direction, before they make a 90 ° bend, so that the shafts 31 or their flake fillings now extend in the horizontal direction. Your horizontal extension ends in front of a riser 10, which on all shafts, essentially in vertical Swipe past from bottom to top and remove the fibers.
  • the mixer as a shaft mixer 3 is achieved due to the different lengths of the shafts 31, that is to say the lengths of the fibers have to cover the fibers later removed in the shaft 31 shown on the left than in the shaft shown on the right. That is based on the different Hatchings recognizable. While the fibers, represented by hatching a, themselves are initially at the same height in their shafts 31, they reach simultaneously fibers, which can be recognized by the hatching b, came into different ways in the shafts 31 Times the riser cloth 10 and so, although they are in the same time Shafts 31 arrived at different times. This takes place Mixing the fibers or fiber flakes with fibers or fiber flakes other times and thus from other bales were fed to the mixer.
