Definitions

  • the present invention relates to a device for densifying fiber flakes into a fiber flake mat.
  • devices for compacting fiber flakes are designed as box feeders, for example as vibrating chute feeders. These feeders densify fluffy fibers into a fiber flake mat, which are subsequently fed to, for example, a web forming machine.
  • Devices for the compression of fiber flakes are for example from EP 0 529 246 B1 . DE 195 38 143 C2 or DE 299 24 648 U1 known.
  • a disadvantage of such devices is that the compaction of the fiber flakes is often irregular and can only be influenced to a limited extent by machine parameters.
  • the apparatus for compacting fiber flakes into a fiber flake mat comprises a means for feeding the fiber flakes, a discharge belt for discharging the compacted fiber flake mat and two cyclically movable walls, which are arranged opposite one another between the means for feeding the fiber flakes and the discharge belt and thus one essentially define a vertical feed chute, which defines a conveying direction of the fiber flakes.
  • at least one of the walls is mounted such that it is movable transversely to each cycle with a component in the conveying direction of the fiber flakes and a component.
  • both walls are mounted so that they are movable in a predetermined manner in each case with a component in the conveying direction of the fiber flakes and a component transverse thereto.
  • a coordinated synchronous movement of the compression effect in the direction of the discharge belt can be further enhanced.
  • the at least one wall is pivotally mounted in its upper region on an upper eccentric arrangement.
  • the direction of movement of the walls is defined in a simple manner both in the conveying direction of the fiber flakes and transversely thereto.
  • the at least one wall should be rigidly mounted in its lower region to a lower eccentric arrangement.
  • the upper eccentric arrangement has a larger stroke than the lower eccentric arrangement, whereby an elliptical movement is generated in the upper region of the wall, while only a circular movement is generated in the lower region.
  • the lower eccentric on a stationary lower shaft which drives a rigidly connected to the lower shaft lower eccentric pin, and a lower connecting rod, which is connected via a preferably ball bearing with the lower eccentric and on the other hand rigid with the wall connected is.
  • the upper eccentric arrangement is preferably constructed similarly, wherein the diameter of the eccentric pin is correspondingly larger and the upper connecting rod is pivotally connected via a connecting bolt connected to the upper connecting rod pivotally connected to the wall.
  • a control device which serves to match the movements of all the eccentric arrangements of the device. This not only standard operations can be specified, but it can be done, for example, in response to the results of a weight measurement of the fiber flake mat produced a corresponding adjustment of the rotational speed of the eccentric shafts.
  • a device according to the invention for the compression of fiber flakes is shown, which is designed as a shaft feeder.
  • the apparatus comprises feed rollers 2 which are driven in opposite directions to convey fiber flakes 4 through the nip between the feed rollers 2.
  • a ⁇ ffnerwalze 6 is arranged, which is designed as a doctor roller with protruding pins or the like.
  • the fiber flakes 4 which have been scraped off by the opener roller 6 pass into a feed chute 8, which is formed by two substantially vertically extending, opposing walls 10.
  • the two walls 10 of the shaft feeder are each connected in their upper end region, each with an upper eccentric 18 and connected in the lower end with a lower eccentric assembly 20.
  • the upper eccentric assembly 18 has a fixed upper shaft 22 which drives a rigidly connected to the upper shaft 22 upper eccentric pin 24.
  • the upper eccentric assembly 18 has an upper connecting rod 26, which is preferably connected via a ball bearing, not shown, with the upper eccentric pin 24 and at the wall 10 facing the end of a connecting pin 28 which is pivotally mounted on the wall 10 is and thus produces a pivotal connection between the upper connecting rod 26 and the wall 10.
  • the lower eccentric assembly 20 includes a fixedly mounted lower shaft 32, which in turn is rigidly connected to a lower eccentric pin 34.
  • the lower connecting rod 36 is also preferably disposed about and connected to the lower eccentric pin 34 via a ball bearing and, on the other hand, is rigidly connected to the corresponding portion of the wall 10.
  • the upper shaft 22 and the lower shaft 32 are driven in unison, thereby moving the wall 10 via the upper eccentric assembly 18 and the lower eccentric assembly 20 in a circular motion with a component of movement in the direction of conveyance of the fiber flakes, i. in the present example vertically downwards, as well as with a component of movement transverse to the conveying direction of the fiber flakes 4, i. in the sense of reducing the width of the hopper 8.
  • the waves of the other wall have a reverse direction of rotation.
  • the walls 10 are preferably formed as perforated plates, possibly also with a slight scaling down, can by the directed in the conveying direction of the fiber flakes 4 component of the eccentric movement entrainment of the fiber flakes 4 through the walls 10 and thus a vertical compression in the direction of the lower output of the hopper 8 made or strengthened.
  • the hopper 8 may also be formed obliquely, the two eccentric pins 24 and 34 may be configured the same size and it may only be a wall 10th movable, the other be designed stationary.
  • the eccentric assemblies 18 and 20 there are various alternatives which are familiar to the expert.
  • Important in any case is the possibility of a cyclical movement, which has both a component in the conveying direction of the fiber flakes 4 in the hopper 8 and a component transverse thereto. For this purpose circular movements, elliptical movements or even rectangular movements come into question.
  • the upper shaft 22 and the lower shaft 32 are coupled for example via chains or toothed belt, but there may also be individual drives for each shaft.
  • control device 42 which controls all shafts 22, 32 and can also be responsible for the movement of the discharge rollers 12 and the feed rollers 2 and the opening roller 6.
  • the density of the fiber flake mat 4 produced can be influenced in a simple manner.
  • the result of any weight measurement of the fiber flake mat produced can be used to adjust the above parameters by the control device.
