Definitions

  • the present invention relates to a feed device for fibers or fiber flocks.
  • a preferred area of application for these types of feed devices is in the production of three-dimensionally molded parts of fiber material.
  • Three-dimensionally molded parts of fiber material are used, for example, in the automobile industry, where they serve to damp sound. They are used, for example, as door linings, rear shelves, and roof linings.
  • the floor and the connecting walls extending from the passenger compartment to the trunk and also from the passenger compartment to the engine compartment are also lined with molded sound-damping parts.
  • the goal is to use one-piece parts with the largest possible area.
  • the sheet metal parts of the car body have a highly sculpted, irregular shape to ensure stiffness and to save material. They comprise seatings for additional components of the vehicle and pass-through openings for cable channels and the steering column, for example.
  • the molded parts used for sound damping must conform to the highly 3-dimensional sculpted shape of these body parts.
  • 3-dimensionally shaped nonwoven parts which consist of a fiber blend or of fibers and an added binder are known from the prior art. These nonwoven parts are produced by the hot molding process.
  • a fiber blend drops down from above into a lower mold so that the fibers accumulate in the lower mold.
  • an upper mold is set down onto the lower mold, so that the loosely piled fibers are compressed.
  • the mold consisting of the lower mold and the upper mold, is subjected to a stream of hot air, so that the fibers fuse together and a molded part is obtained.
  • the inside surface of the lower mold determines the contour of the bottom of the molded part
  • the inside surface of the upper mold determines the contour of the top of the molded part.
  • 3-dimensionally shaped molded parts can also be structural parts, which can transmit force and can have a load-bearing function.
  • U.S. Pat. No. 3,791,783 A discloses a device for the production of molded parts made of fibers. Chopped fibers are applied to the inside surface of a horizontally rotating, screen-like mold. The feed is accomplished through a pipe, which can be moved horizontally. The fibers deposited in the mold are pressed against the mold by an external vacuum, which surrounds the outside surface of the mold. Then the fibers are coated with a spray consisting of a synthetic resin binder, which cures when heated. The fiber-filled mold can then be subjected to a stream of hot air to cure the molded part.
  • U.S. 5,942,175 A discloses a method and a device for the press-molding of loose clusters of fibers.
  • loose fiber clusters are distributed in the mold from above by means of a tube in such a way that areas of different density can also be created if desired.
  • the fibers are blown into a closed mold by a stream of air, wherein different filling densities within the mold can be realized by setting the flow velocities of the individual air inlets to different values.
  • a press is lowered, so that the fiber agglomerates are compressed inside the mold. Hot air is then supplied to bond the fiber clusters together, so that a molded body is obtained.
  • Feed devices for fibers or fiber flocks are also used in other areas of application for the production of fiber materials, such as in the production of fiber flock mats or fiber fleeces.
  • the attempt is made here to make the fiber flock mat or the fiber fleece as uniform as possible across its entire width.
  • it may also be desired to give the fiber flock mat or the fiber fleece a 3-dimensional profile.
  • the feed device for scattering individualized fibers or fiber flocks comprises a scattering section, in which a driven feed roller and a driven opening roller cooperating with the feed roller are arranged, wherein a dispensing device for storing and dispensing a fiber sliver or fiber fleece strip is assigned to the feed roller in such a way that the feed roller pulls in the fiber sliver or fiber fleece strip provided by the dispensing device, as a result of which the feed roller is fed with the fiber sliver or fiber fleece strip.
  • the opening roller is arranged adjacent to the feed roller in such a way that it opens up the fiber sliver or fiber fleece strip pulled in by the feed roller to form individual fibers or flocks and scatters them.
  • the scattering section is preferably arranged at one end of a feed arm. If the feed arm is movable in one, two, or three dimensions, the areas of application and the flexibility of the feed device can be increased even more. With a design which allows two-dimensional movement, for example, any desired fiber profile can be effectively scattered onto a mold without the need for the mold itself to move.
  • the feed arm is a pivoting arm with two legs, which are jointed to each other at a first pivot axis, wherein the scattering section is arranged at the end of the second leg.
  • the first leg is preferably supported with freedom to pivot around a second pivot axis, as a result of which the feed device is given mobility in a second dimension.
  • the fiber sliver or fiber fleece strip can be supplied especially effectively to the scattering section if the feed arm comprises a deflecting pulley in the area of its first pivot axis to guide the fiber sliver or the fiber fleece strip as the fiber sliver or the fiber fleece strip travels between the dispensing device and the feed roller.
  • the feed roller can comprise a set of surface fittings with teeth projecting backward with respect to the rotational direction of the feed roller, wherein the opening roller is driven in the same rotational direction as the feed roller and comprises a set of surface fittings with teeth projecting forward with respect to this rotational direction.
  • the feed roller can comprise a set of surface fittings with teeth projecting backward with respect to the rotational direction of the feed roller, wherein the opening roller is driven in a second rotational direction, which is opposite the rotational direction of the feed roller, and comprises a set of surface fittings with teeth projecting forward with respect to the second rotational direction.
  • the feed roller usually has a width in the range of 5-50 mm, preferably of 15-30 mm, and even more preferably of 20-25 mm.
  • a blower can be arranged in the area of the scattering section to generate a stream of air, which blows the fibers opened by the opening roller toward the mold. This can be supported by suction acting from underneath the mold.
  • the feed device can comprise a heating coil or a gas burner in the area of the scattering section, so that the air stream is also heated at the same time.
  • a heating coil or a gas burner in the area of the scattering section, so that the air stream is also heated at the same time.
  • This can be advantageous in certain applications in which the intermediate fiber product is subjected to a heat treatment.
  • An example is the treatment of a mixture of fibers and hot-melt adhesive, wherein the latter is melted by the stream of hot air.
  • the feed device also preferably comprises an automatic control unit to change the speed of the feed roller as a function of the scattering position of the scattering section. Programming the automatic control unit in advance precisely defines the scattering speeds and thus the quantities which are scattered as well as the associated pattern of movement of the scattering section.
  • the feed roller is preferably driven by a servomotor, which makes it possible to dose the fibers scattered by the feed device with precision.
  • the feed device comprises two individually actuatable feed rollers, which are arranged next to and parallel to each other.

  • Feed arm 4 in this case is a pivoting arm with two legs 8 , 10 , which are connected to each other to form an inverted V at a first, preferably horizontal, pivot axis 12 in the area where legs 8 , 10 intersect.
  • the second leg 10 is connected pivotably to first leg 8 via first pivot axis 12 in such a way that the angle between two legs 8 , 10 , i.e., the angle of the inverted V, can be made larger or smaller by the pivoting of second leg 10 .
