Definitions

  • the invention relates to a method or an apparatus for Preparation of a fiber mass for a fiber sorting device.
  • a fiber sorting device is known from EP-A-0 282 996, wherein in the space between two opposite and rotating sieve drums Fibers are fed. There is an electrical voltage at the sieve drums created, whereby the fibers in the space are horizontal or to align vertically. It is envisaged that the short fibers, which Due to their length, only one of the two screening drums can be used to capture the Openings of the respective screening drum are suctioned off and thus separated. The long fibers, which are to be held by both Si drums at the same time then be removed on a conveyor belt. A targeted and controlled leadership the fibers before being fed into the separation area are not provided, whereby there is a risk that long fibers will also be separated.
  • the invention relates to a method or an apparatus for Preparation of a fiber mass for a fiber sorting device.
  • the object of the invention is therefore to provide a method or a device Preparation of the fiber mass to propose for a fiber sorting device improved fiber selection is made possible.
  • the fiber mass to be processed is processed into individual fibers lying essentially next to one another and, as seen in the transport direction of the fiber mass, longitudinal fibers and the fibers thus aligned are guided in their position to a subsequent sorting device.
  • This type of preparation enables each individual fiber to be treated in a targeted manner during the sorting process and ensures that the individual fibers are introduced into the sorting area in their longitudinally extended position and lying next to one another in parallel. It is particularly important that the individual fibers are held in their position on their transport route to the sorting device after their longitudinal alignment and separation. This ensures that the fibers can be held in a targeted manner in the sorting area and only the undesired short fibers are separated, while the long fibers remain in the fiber mass. Furthermore, it is proposed that the fiber mass be subjected to at least one warp for the longitudinal alignment and parallelization of the fibers.
  • the isolated and longitudinal fibers a sieve drum, in the interior of which at least partially a vacuum is created. With this device, the fibers are transported to Sorting device held securely in place.
  • the fiber mass is broken down into individual fibers, which are then - viewed in the transport direction - aligned in the longitudinal direction and approximately parallel to one another.
  • the fiber mass can then be subjected to a warp after the longitudinal alignment of the fibers.
  • the fiber mass be widened before the fibers are separated and aligned longitudinally. This makes it possible to increase the throughput of fiber material per unit of time
  • a device for preparing a fiber mass for a fiber sorting device is proposed, the fiber mass to be processed being warped in a drafting unit, so that at the exit of the drafting unit there are fibers lying essentially next to one another and aligned in the longitudinal direction and these fibers in their position via at least one guiding means Fiber sorting device are supplied.
  • a sieve drum is preferably selected as the guide means, in the interior of which a vacuum is applied at least in the transfer area to the fiber sorting device. With this device, the individual fiber is securely held or guided.
  • the screening drum be part of the delivery roller pair of the drafting unit and cooperate with a pressure roller. This makes it possible to hold the fibers emerging from the drafting system directly on the sieve drum and to guide them safely by means of the negative pressure applied within the sieve drum.
  • the drafting unit can preferably be provided with an apron drafting device.
  • the drafting unit is preceded by a device with which it is possible to widen the fiber mass presented to the drafting unit. This means that the throughput per unit of time can be increased, although it may only be necessary to adjust the width of the drafting rollers.
  • the fiber mass to be processed being broken up into individual fibers by a dissolving roller, which are then released via a guide channel onto the peripheral surface of a rotatably mounted sieve drum, in the interior of which a partial vacuum is applied.
  • means are arranged in the guide channel which bring about an alignment of the fibers emitted by the opening roller so that they hit the subsequent screen drum approximately in the tangential direction.
  • the means can serve, for example, to build up an electrostatic field transversely to the conveying direction of the fiber material. Due to the corresponding polarization of the fibers, these are aligned by applying an electrical voltage and thus reach the subsequent screen drum approximately in a tangential orientation.
  • the proposed widening of the conveyor channel favors the separation of the fibers.
  • a device can be arranged upstream to increase the productivity in order to broaden the fiber mass presented.
  • edges of the fiber mass presented during the broadening process are not are negatively influenced (fraying or thinning of the edges) proposed to provide guide means that a in the area of widening Apply a clamping effect to the fiber material.
  • the fiber sorting device be made approximately tangential to the Air flowed through the sieve drum, to the interior of which a vacuum is applied Channel is formed, which is provided with an opening facing the screening drum, in which partially immerses the sieve drum and its air flow in the direction of rotation the screening drum shows and at least over a portion of the opening on the Air-impermeable means are provided on the inner surface of the screening drum Prevent air flow through the screen jacket from the outside in.
  • the selection process e.g. through an air flow then can be optimally carried out if the fiber material in the form of single fibers lying next to each other is exposed to the air flow. Also is the stretched parallel position of the fibers in the direction of transport for a targeted separation to be carried out important. This ensures that the long Fibers due to the holding force applied during the separation process in each Case held and excluded from deposition. By submitting in The form of individual fibers also ensures that each fiber is through the Air flow can be applied. It is therefore important that the processed Amount of fibers with the isolated and longitudinal fibers in its structure is retained until it reaches the separation area. As a result, the Fibers according to their longitudinal orientation and separation on the whole Transport route are guided until they reach the separation area. in the As already described, the separation area then becomes the fibers of a holding force subjected and exposed to an air flow. The fibers that come from the Holding force released, are carried along by the air flow and separated.
  • the invention is not limited to the claimed preparation of the fiber mass in combination with a sorting device in the form of an air-flow channel into which the sieve drum is immersed. Rather, other sorting devices can also be used to process the fiber mass prepared according to the invention.

It can be seen from this that the length of the cover element 15 is designed in this way must, so that only the fibers are removed from the air flow, which as Short fibers are to be separated.
  • All fibers and other components e.g. shell parts and other Impurities
