Definitions
- the invention relates to a device on a spinning preparation machine, for. B. card, line or the like, for guiding and compacting a fiber structure from at least one fiber band, in which there are at least two funnel-like guide elements one behind the other, which have several wall surfaces in succession, along which the fiber structure slides and is brought together, the between
- Inlet opening and the outlet opening is at least one wall zone in which the fiber structure is connected to the outside air via an opening.
- two funnel-like guiding elements are arranged one behind the other between a fibrous web guiding element and a pile funnel, one funnel-like guiding element being opened completely downwards in the wall area, while the other funnel-like guiding element is completely open upwards in the wall area.
- the two guide elements are each formed from three wall surfaces, two of which lie opposite one another. At approximately a right angle to it, the two opposite wall surfaces are each connected on one side to a third wall surface, while the other side opposite this is designed as a continuous opening, i. H. the guide element is open on one side.
- the two opposite wall surfaces of the guide elements are - viewed in succession - aligned parallel to one another.
- the pile funnel has closed wall surfaces on all sides.
- the invention is therefore based on the object of providing a device of the type described at the outset which avoids the disadvantages mentioned, in which, in particular, the compression of the fiber material and the air outlet from the fiber material are evened out.
- the device consists of two or more guide elements, each individual guide element according to the invention consisting of only two opposite wall elements, so that the fiber material is compressed in only one direction. Because each wall element is open on both sides, the escaping air can escape to the same extent on two sides. In this way, the compression and the air outlet are evened out.
- Friction on the side wall surfaces is completely absent due to the side openings.
- the compression takes place in only one direction, for. B. in the vertical arrangement of the wall elements in the transverse direction and in the immediately adjacent guide element due to the horizontal arrangement of the wall elements in the vertical direction, d. H. Compression direction and air outlet device alternate.
- the measures according to the invention in particular due to the symmetry of the device, advantageously combine the compression and the air outlet.
- the angle is expediently 90 °. Is preferably between two neighboring ones
- the wall elements advantageously have a circular cross section.
- the wall elements consist of a rod, a rod, bolts or the like.
- the wall elements consist of a wear-resistant material, e.g. B. hardened steel.
- the wall elements are preferably stationary during operation.
- the wall elements are advantageous for conveying the
- Fiber material rotatably driven At least one wall element of a guide element is preferably movable, e.g. B. displaceable, pivotable or the like ..
- a guide element and a band funnel are expediently alternately present.
- the fiber guide member 10 is preferably arranged at the exit of a card. With The fiber guide element is advantageously arranged as a band funnel (34) at the exit of a draw frame. Two take-off rollers are preferably arranged downstream of the fiber guide element. At least one measuring element for the thickness of the fiber structure is expediently assigned to the fiber guide element. , --- - . '- _

- the directions of rotation of the rollers are shown with curved arrows.
- the pile hopper 10 shown schematically is designed according to the invention.
- the drafting arrangement 17 is designed as a 4-over-3 drafting arrangement, i.e. H. it consists of three lower rollers I, II, III (I output lower roller, II middle lower roller, III input lower roller) and four upper rollers 25, 26, 27, 28.
- the fiber structure 20 is drawn from several fiber strips. The delay is made up of early default and main default.
- the roller pairs 28/111 and 27/11 form the pre-drafting zone, and the roller pairs 27/11 and 25, 26/1 form the main drafting zone.
- the drawn fiber slivers 29 reach a fleece guide 30 in the drafting device inlet and are pulled by means of the take-off rollers 31, 32 in the form of a bandage 38 through a belt funnel 34, in which they are combined to form a fiber sliver 35, which is then deposited in cans.
- the take-off rollers 31, 32, the input lower roller III and the middle lower roller II, the mechanically z. B. coupled via toothed belts, are by the control motor 36th driven, a setpoint being predeterminable. (The associated upper rollers 28 and 27 run with it.)
- the output lower roller I and the take-off rollers 31, 32 are driven by the main motor 37.
- the control motor 36 and the main motor 37 each have a separate controller 38 or 39.
- the control (speed control), ⁇ is made via a closed control loop, wherein the controller 36 is assigned a tacho generator and the main motor 37, a tachometer generator.
- a quantity proportional to the mass e.g. B.
- Band funnel 34 is designed according to the invention.
- a central computer unit (41) (control and regulating device), for. B. microcomputer with microprocessor, transmits a setting of the target variable for the control motor 36 to the controller 38.
- the measured variables of the two measuring elements 24 and 40 are transmitted to the central computer unit 41 during the stretching process.
- the target value for the control motor 36 is determined in the central computer unit 41 from the measured variables of the inlet measuring element 24 and from the target value for the cross section of the emerging fiber sliver 35.
- the measured variables of the outlet measuring device 40 serve to monitor the emerging sliver 35 (output sliver monitoring).
- the fiber guide element consists of four guide elements 41 to 44, which are each formed from two wall elements 41a, 41b to 44a, 44b located opposite one another.
- the wall elements 41a to 44b consist of rod material, e.g. B. made of hardened steel, with a circular cross-section.
- the opposite wall elements of each guide element 41 to 44 are arranged parallel to one another and have a distance a, b, c and d between the wall elements 44a, 44b, 43a, 43b, 42a, 42b and
- each guide element 41 to 44 is open on both sides.
- Guide elements 41 to 44 which are arranged one behind the other in each case, are arranged at an angle of 90 ° to one another with respect to the longitudinal axis of the device, which essentially corresponds to the working direction A. 4, the wall elements 41a, 41b, 43 a, 43b are rotatably supported and by an endlessly rotating drive element, for. B. straps 45, over a
- the wall elements 42a, 42b, 44a, 44b are rotatably supported and driven in a corresponding manner (not shown).
- a driven draw-off roller pair 11, 12 is arranged downstream of the output of the fiber guide member, the rollers of which can be rotated in the direction of the curved arrows.
- a distance e, f or g is present in each case between two adjacent guide elements 41 to 44. In this way, air can escape, which emerges from the fiber structure in the direction of the arrows during compression.
- F is the fiber material.
- the fiber guide element consists of two guide elements 47, 48, which are each formed from two wall elements 47a, 47b and 48a, 48b located opposite one another.
- the wall elements 47a, 47b and 48a, 48b are designed as profile pieces.
- the wall element 48b is (in a way not shown) in the direction of the arrows B, C and the wall element 47a is (in a way not shown) in the direction of the arrows D, E. In this way, the gaps 49 and 50 between the wall elements are changed, whereby the piecing (introduction of new slivers F) is made possible or facilitated.
- FIG. 7 shows how the cross section of the fiber structure F decreases in the working direction A and the fiber structure F is compressed in the process.
- the escaping air escapes both through the lateral openings between two parallel wall elements 47a to 50b and through the spaces e, f and g between guide elements arranged one behind the other.
- the fiber material is compressed between two wall elements 47a, 47b, 48a, 48b, 49a, 49b and 50a, 50b only in one direction, e.g. B. in the vertical or horizontal direction. Because the fiber material in a guide element 47 to 50 only slides along the two surfaces of the opposing wall elements 47a to 50b, but there is no sliding surface to the side because of the opening, the friction is reduced. Characterized in that the adjacent guide elements 47 to 50 are each rotated by 90 ° to each other, the fiber structure can - if there are openings to the sides of a guide element - by the
