Definitions

  • the invention relates to a method and a device for recovering long parts according to the preamble of claims 1 and 6 respectively.
  • JP-A-52 103 759 discloses a device in which a multi-layer material layer is fed to a drum, through which a wheel studded with rods protrudes outwards, which passes through the layer with the rods from bottom to top and thereby long parts on the Conveyed top of the drum, which in turn then in cooperation with an endless belt feeds a container.
  • This device also requires considerable height and is expensive in terms of equipment.
  • the invention has for its object to provide a method and an apparatus that, in particular with little structural effort, a high recovery rate of long parts to be separated from a solid mixture Allow wires.
  • the wires contained in the screened solid mixture of small grain size which is preferably supplied in one layer by a conveyor in order to achieve an optimized recovery rate, are mainly in this mixture with lengths below 100 mm and thicknesses of 0.05 mm (hair-thin) to 3.5 mm (thick wires) are present - picked up by the brush, while the other, body-shaped mixture components pass through the brush without being held back or even jammed due to a sweeping effect.
  • the mixture components to be recovered be separated in a multiple brush pass. It can then namely achieve an extremely high degree of efficiency and the like, using the example of the recovery of wire pieces, pins or the like. described from a solid mixture - cut off almost the entire wire portion from the solid mixture, since the different thicknesses of the wire pieces can be matched by appropriate design or selection of the brushes.
  • a dense bristle made of nylon with a bristle thickness of 0.4 mm and a bristle height of 100 mm with an outer diameter of the brush of about 300 mm.
  • the bristles should be rather coarse - with otherwise the same criteria as previously mentioned for the thin wires - and a bristle thickness of 0 , 6 mm.
  • the bristles offer a larger contact surface for receiving the wire pieces. Above all, thicker pieces of wire from the solid mixture can be better absorbed if they run into the bristles lying transversely on the conveyor; on the other hand, thinner wires spin faster in the bristles of the brush, even if they are fed lengthways.
  • the brush which preferably rotates in the same direction, and the conveyor can alternatively be driven in opposite directions. Regardless of the direction of rotation, it is advisable to drive the conveyors and the brushes at the same speed, which largely prevents wear of the bristles due to the output.
  • a device for separating mixture constituents, such as pieces of wire from the aforementioned, sieved solid mixture, which is composed of body-shaped constituents up to 10 mm in grain size and said pieces of wire, has the features according to claim 5.
  • the brush rollers commercially available, but also round or belt brushes can be used as brushes.
  • the bristles can be attached to the brush body tangentially and / or spirally as well as with gaps - so that the body-shaped mixture components cannot accumulate.
  • endless belt conveyors as well as turntables, chutes, and - optionally with sieve openings - drums come into question.
  • a feed conveyor end over a lower-lying, the brush-containing discharge conveyor preferably designed as an endless belt conveyor.
  • the difference in height between the feed conveyor and the lower-lying, preferably designed as an endless belt conveyor is so great, for example 100 to 150 mm, that a shifting of the wire pieces can occur during free fall; this means that wires on the feed conveyor still lying in the conveying direction then have one on the discharge conveyor Take up position transverse to the direction of transport and thus in the axial direction of the longitudinal axis of the brush.
  • the feed conveyor can advantageously be designed as a vibrating trough in which a single-layer spreading of the solid mixture results due to the vibrations during the feed. If the feed conveyor advantageously runs transversely to the discharge conveyor, wires fed on the feed conveyor lie in a longitudinally aligned position on the discharge conveyor after the transfer transversely to the direction of conveyance. It is recommended that the feed conveyor be provided with longitudinal grooves. The grooves support that the wires, which are aligned in the longitudinal direction due to the vibrations of the vibrating trough, then maintain this position until they are transferred to the conveyor; there they lie transversely to the transport direction and thus in the longitudinal direction to the brush axis.
  • successive discharge conveyors each having at least one brush
  • the discharge conveyors can be arranged in a line, but preferably each discharge conveyor runs transversely with respect to the upstream discharge conveyor in each case
  • the layers of the wire pieces can be rearranged during transfer either during the free movement If and / or because of their supply in a longitudinally aligned position, reach across to the following conveyor.
  • the wire pieces thus run into a brush lying at least once in the longitudinal direction to the brush axis.
  • the discharge conveyor (or the discharge conveyor) can be arranged either horizontally or inclined in the conveying direction.
  • inclined conveyors With inclined conveyors, the feed is smaller of the wire pieces through the brush favoring the pull-in angle, because the bristles come into contact with the solid mixture earlier and have time to adapt to the mixture components penetrating into the bristles.
  • inclined conveyors require a larger amount of space, particularly in the case of a cascade arrangement.
  • the head ends of the conveyors be provided with an inclined distributor edge that extends across the width of a lower-lying discharge conveyor. This is particularly recommended if the following conveyor is arranged transversely to the previous conveyor, because the wire pieces or the solid mixture can then be distributed over the entire width - about 600 mm - of the conveyor. If the conveyor is a belt conveyor, it can be provided with a chute having the distributor edge; a vibrating trough can have the distributor edge directly at its head or discharge end.
  • the bristles of the brushes advantageously extend to the surface of the conveyor, the bristle length in conveyors with a profiled surface being set to the "valley", ie the deepest point of the surface profile.
  • Such bristle supports that the wire pieces to be picked up better press into the bristles. While the pieces of wire do not deflect the bristles and thus get caught in the bristle, the body-shaped components push out of the bristles after passing the narrowest point between the bristle and the conveyor surface.
  • a brush can advantageously be provided at the head end of each removal conveyor; alternatively, the brush can be arranged in front of the head end above the discharge conveyor.
  • the last-mentioned embodiment makes it possible to take off pieces of wire of different thicknesses with only one removal conveyor, because there is sufficient space in the conveying direction to optionally provide a second or third brush, each with different bristles, above the same removal conveyor.
  • the brushes can be arranged or adjusted obliquely to the conveying direction, making it possible to adjust the brushes in the horizontal plane in the case of obliquely fed wires in such a way that their longitudinal axes run parallel to the pieces of wire.
  • brushes with different bristles can be arranged on an axially displaceable drive shaft.
  • a solid mixture treated in a first brush pass can then be placed on the same conveyor and the brush adapted to the wire pieces to be separated in this pass can be used by moving the drive shaft sideways.
  • the arms of an at least two-armed rotary arm can be provided with self-propelled brushes which are bristled differently from arm to arm. In the case of brushes mounted on rotating arms, it is possible to replace the brushes which are in an out-of-operation position during operation.
  • a driven, combing with the brush pickguard roller with at least two wings can advantageously be provided to remove the wires picked up by a brush from the Remove the bristles, ie knock them out or comb them out. Another option is to remove the wires with a harder and faster rotating brush.
  • the pickguard rollers which advantageously rotate in the same direction as the brushes, should have at least two flapping wings in order to avoid imbalance; when combing or combing out, however, we recommend at least four blades.
  • the feed conveyor ends at a distance from the bristle above the brush.
  • a horizontally and / or inclined discharge conveyor (belt conveyor)
  • the feed conveyor advantageously ends in front of the upper apex of the brush, so that the solid mixture comes into contact with the bristles in the region of the circumference of the rotating brush which rises in the circumferential direction; during the remaining time, i.e. until the upper vertex is reached, the pieces of wire have the opportunity to get stuck in the bristles.
  • a flexible roller that loads the brush from above after the material has been added.
  • the wires get stuck in the bristle due to insufficient deflection of the bristles, the body-shaped mixture components push out of the bristle after passing through the pressure roller and thus fall down early.
  • the wires held in the bristle are carried further - possibly beyond the lowest point of the brush (lower apex of the brush) - and only then are they removed from the bristle.
  • a comb pickguard
  • a comb which can be swiveled and adjusted in height, can be immersed in the bristles.
  • a, optionally adjustable, separating saddle is arranged on the discharge side of the brush, it contributes to keeping the body-shaped components falling out of the bristle at an early stage and the pieces of wire combed out or combed only much later in the direction of rotation of the brush, since namely the body-shaped components in front and the pieces of wire fall down behind the separating saddle.
  • a brush running obliquely to the conveying direction be immersed in the conveyor up to approximately half its diameter, which is preferably designed as a slide.
  • the brush deflects the body-shaped components of the solid mixture supplied on the chute in a different direction according to its inclined position, while the wire pieces are lifted or lifted by the brush and thus be removed from the flow; a spiral bristle of the brush supports the removal or lifting effect.
  • a separating device for separating wires 1 (see FIGS. 9, 10, 11 and 14) from a pre-sorted solid mixture containing, in addition to wires, body-shaped components with a grain size of up to 10 mm, the solid mixture is - as in all the exemplary embodiments shown in the drawings - via a bunker 2 to a vibrating trough 3 designed as a feed conveyor.
  • the solid mixture is homogenized in height and width on the vibrating trough 3, and at the same time the wires 1 are aligned in the longitudinal direction, supported by longitudinal grooves 5 on the surface of the vibrating trough 3, whereby the wires 1 maintain their aligned position (see FIGS. 1 and 2).

  • the wires 1 are thus at least once brought into such a position during the multi-stage treatment process that they are transported on the belt conveyor 6 in the direction of the longitudinal axis of the brushes 11, 11 ', 11' 'and thus transversely to the conveying direction 7, as in FIG 5 for the wires 1 lying on the belt conveyor 6 '.
  • Such a position of the wires 1 is preferably achieved in that the feed conveyor 3 runs transversely to the belt conveyor 6 (see FIGS. 1 and 2) and / or each belt conveyor with respect to the respective upstream belt conveyor 6, 6 ', 6' ' is arranged transversely, as shown in Figs. 3, 4, 5 and 8.
