Definitions

  • the invention relates to a feed cylinder for a nipper unit of a comber, which is connected via a gear stage with an electric motor drive.
  • the invention relates to a method for adjusting the Auskarmm seat on a comber for forming a combed nonwoven fabric with a feed cylinder formed according to the invention.
  • the invention also relates to a combing machine with at least one feed cylinder designed according to the invention.
  • the invention is therefore based on the object to propose a solution, wherein the feed cylinder can be driven individually via an electric motor and the disadvantages of known solutions can be avoided.
  • This object is achieved by proposing that the electromotive drive and the gear stage for driving the feed cylinder is mounted within the hollow cylinder formed as a feed cylinder.
  • the electromotive drive (or the electric motor), as well as the transmission elements are in a sealed space within the hollow body of the feed cylinder and are thus protected against contamination.
  • the mass of the electric motor integrated in the feed cylinder is relatively low, so that no large additional loads (energy, bearing loads) occur when the motor is moved during the comb play.
  • the feed cylinder is rotatably supported by bearing elements mounted on bearing sleeves which project at the ends of the feed cylinder into its cavity.
  • the electromotive drive and the gear stage between the protruding into the feed cylinder bearing sleeves is arranged, wherein the gear stage on the one hand rotatably connected to the motor shaft of the electric motor drive and on the other hand rotatably connected to the hollow body of the feed cylinder.

  • the control part is also located within the cavity of the feed cylinder.
  • bearing sleeves for mounting the hollow cylinder, it is possible to let the leads to the electric motor drive through the cavity of the bearing sleeves.
  • the electric motor drive has a servo motor.
  • a method for adjusting the Auskarmm seat on a comber with a driven via an electric motor drive feed cylinder of a nipper unit is proposed to form a combed nonwoven fabric. It is proposed that the ratio of the lengths of the, for the combing process and for the tearing off over the nip of the nipper unit protruding fiber mass is determined by a controlled movement of the feed cylinder with respect to the rotation angle and the direction of rotation.
  • the ratio of the lengths is determined by: length of fiber tuft for the combing / length tuft for the tearing off.
  • the Ecartement (smallest distance between the lower pliers plate and the nip of the subsequent Abreisswalzen) is adjusted to determine the Auskarmm Abu (percentage of the noils). This is done on an adjusting device in the area of the forceps shaft and can only be done in machine downtime. This setting is time consuming and restricted to certain levels.
  • flexible adjustment of the combing height can only take place via the controller even during operation. This makes it possible, for. B.
  • a method for forming a nonwoven fabric on a combing machine using the present invention claimed feed cylinder is proposed, in each case before the closing of the nip of the nipper unit the previously fed dining is withdrawn by a predetermined partial amount, so that when the nipper unit (short: pliers ), which has a Kämmsegment submitted free end (also called "tuft") of the fiber material, a shortened by this partial amount length.
  • This partial amount can be determined exactly by the reversing movement of the feed cylinder.
  • a spinning mill owner is anxious to obtain as high a productivity as possible in achieving a required quality.
  • the quality desired by the customer for the combing machine belt produced on the combing machine can be maintained, it is recommended to obtain as little as possible (notch) on the combing machine.
  • the essential point is that the variation of the length of the tuft presented for the combing process takes place by means of a controlled rotational movement (forward and reverse rotation) of the feed cylinder.
  • the set of a Fixkammes brought into engagement with the tuft.
  • the fiber material pulled out of the fiber tuft via the tear-off device for example a pair of tear-off rollers

  • the comber is provided with a central input point via which the size of the meal amount, the size of the portion of the Edible amount and the time interval of the meal and the partial amount of the meal are adjustable.
  • the swivel arm S1 (it may also be two) is, as indicated by a double arrow, moved back and forth via a pincer shaft ZW. It is pivotally attached via a pivot axis 22 to a forceps frame 3 of the forceps.
  • one (or two) pivot arm S2 is connected to the tong frame 3 via a pivot axis 23, its other end being supported on a shaft 9, rotatably mounted in the machine frame, of a circular comb 8.
  • the circular comb is provided on its outer circumference with a combing segment 10.
  • the forceps 2 has a lower forceps plate 4, which is fixedly attached to the forceps frame 3.
  • an upper pliers plate 5 (also called “pliers knives”) is pivotally mounted via a pivot axis 6 and via pivot arms B1, B2, as indicated by a double arrow.

  • the Abreisswalzencru can follow another unspecified pair of rollers to support the soldering process.
  • a rotatably mounted feed cylinder 12 attached above the lower nipper plate 4 in the jaw 2 .
  • the feeding of the meal is done intermittently within a certain time interval during a comb game. Modern combers can perform up to 600 combs per minute.
  • the intermittent drive of the feed cylinder 12 takes place in the present example by an electric motor drive M (short: motor), which is mounted within the cylinder designed as a hollow cylinder, as from Figure 3 can be seen, which will be discussed in more detail below.
  • Fig.2 shows the pliers 2 in a rear position in which it is closed.
  • the forceps knife 5 (upper tong plate) is pressed under the action of at least one, schematically indicated spring arm FD with pressure in the region of the clamping point KS against the lower tong plate 4 and thus the fiber material W clamped in this area.
  • the respective angle of rotation of the circular comb shaft 9 is scanned by a sensor 18 and transmitted via a line 19 to a control unit ST.
  • control unit ST is connected to a control part S, which is also within the hollow cylinder H of the feed cylinder ( Figure 3 ) is arranged and via which the motor M is controlled within the feed cylinder 12.
  • control part S Integrated in the control part S (not shown) is a rotary encoder, via which the respective angle of rotation of the motor shaft M1 of the motor M is detected.
  • the motor via the control part S and the line 26 is connected to a power source 30 shown schematically.
  • the fiber beard FB projecting beyond the clamping point has a length L1 which is shortened by this partial amount a.
  • D. h for the combing process ( Fig.2 ), a shorter tuft FB (with the length L1) is available than for the subsequent tearing process (with the length L).
  • FIG. 3 schematically shows a cross section through the inventively proposed feed cylinder 12, which consists of a hollow cylinder H, in which an electric motor drive with a motor M, a gear G and a control part S is mounted.
  • the control part S is still a rotary encoder connected, which is not shown in detail and via which the respective rotational angular position of the motor shaft tapped and the control part S is transmitted.
  • the electromotive drive is located in the cavity HR of the hollow cylinder H between two bearing sleeves 32, 33, on which the hollow cylinder H is rotatably supported via bearings N.
  • the bearing sleeves 32, 33 are held by bearing elements 14, 15, which are fastened on the tong frame 3.
  • the bearing elements 14, 15 can also be designed to simplify assembly of the bearing sleeves 32, 33 in two parts (not shown). In order to gain access to the attachment of the electric motor drive within the cavity H and to receive for the supply of lines (power cables, control lines), the bearing sleeves 32, 33 on a central passage opening D.
  • the motor M which forms a unit with a control part S, is fixedly connected to the bearing sleeve 14 via fastening means, not shown.
  • the output shaft M1 of the motor M protrudes into a transmission G in which a speed reduction takes place.
  • the reduced speed is transmitted to the output surface M2 of the transmission G on the inner surface of the hollow cylinder H of the feed roller 12.
  • the control of the motor speed, as well as the angular movement of the shaft W2 via the control part S which in turn is connected via the guided through the bearing sleeve 32 line 25 with a central control unit ST.
  • a coupling 34 rotatably mounted on the shaft M2.
  • a threaded bore 41 is attached on the end of the coupling (viewed in the axial direction to the axis of rotation 11 of the feed cylinder) which is opposite to the end in which the receiving bore 37 for the shaft M2 is located.
  • a screw 38 is screwed, which projects through a bore B of a disc 36.
  • a slotted clamping ring 35 Between the clutch 34 and the disc 36 is a slotted clamping ring 35, the outer circumference U rests in the clamped state on the inner surface H1 of the hollow body.
  • the clamping ring 35 is provided at its two end faces with inclined clamping surfaces K, on which rest oblique surfaces, which are each attached to an end face of the coupling 34 and the disc 36.
  • the disc 36 is clamped against the clutch 34.
  • the outer diameter of the slotted clamping ring 35 is enlarged via the clamping surfaces K, whereby the outer circumference U of the clamping ring comes to rest on the inner circumference H1 of the hollow profile and forms a firm clamping connection.
  • control unit ST desired feed amounts and feed intervals for the control of the motor M of the feed cylinder 12 via the control part S (depending on material, combing, stack length, etc.)
  • the control unit is provided with an input unit 44 (eg keyboard) and a optical display 45 (eg, screen) via line 47.
  • corresponding values can be predetermined as a function of the corresponding material template and the desired combing-out in order to correspondingly control the rotational movement of the feed cylinder via the motor M.
  • the rotation angle of the circular comb shaft 9 is accurately detected by a sensor 18 which transmits its signals via the line 19 to the control unit ST.
  • the values entered via the keyboard 44 are brought into agreement with the rotational angle position of the circular comb shaft via an existing program (software) and the control part S of the motor M is controlled accordingly.
  • a rotation angle detection not shown for the shaft M1 of the motor M is present, which z. B. may be integrated in the control part S.
  • the smallest distance E (also called “ecartement”) between the pliers and the tear-off rollers is at index 24, at which the pliers again start their rearward movement direction. This position is also referred to as forward dead center VT.
  • the pliers knife is located between the index 34 to index 10 in a clamping position with the lower pliers knife with which the pliers is closed in this period of time. As can be seen in the lower part of the diagram, during this period, the combing process (combing) by the combing segment 10 of the circular comb 9 takes place.
  • the pliers are the furthest open at the front dead center VT.
  • the closing movement of the pliers then takes place on their backward movement between index 24 and index 34.
  • the feeding of a meal b for the combing process is carried out by forward rotation ( Fig.1 ) of the feed cylinder, or by appropriate control of the motor M via the control part S.
  • This feed starts at index 14 and ends at index 24, in which the foremost position of the clamp is reached.
  • the tearing off by the Abreisswalzen already takes place before reaching the foremost position of the pliers. This is generally known (see, for example, The short staple spinning mill; Volume 3; The Textile Institute; Page 31; ISBN 3-908.059-01-1 ) which is not discussed here. Also on the presentation of the intervention of a Fixkammes before the Anbreissvorgang is omitted here.
  • the previously supplied feed amount b is withdrawn during the backward movement of the pliers between index 24 and index 34 again by the partial amount a. This is done by a corresponding control of the motor M of the feed cylinder via the control unit ST, or via the control part S, whereby the motor M is set in a reverse rotation, such. B. schematically by the dashed arrow in FIG Fig.2 is hinted at. This return must be completed in any case, before the pliers at index 34 is completely closed.
  • the proposed drive and control device for the feed cylinder also allows appropriate adjustments when a return feed or a mixed feed (feed combined in flow and return) is provided. That via the control of the electromotive drive for the feed cylinder is made possible that the length of the tuft FB during tearing (in VT) may be different than the length of the fiber tuft FB during combing (HT) without the Ecartement (distance E) must be adjusted ,
