Definitions

  • the invention relates to an adjusting device on a card according to the preamble of claim 1.
  • Fig. 1 shows an arrangement known from EP-A-432430. It embraces itself below and along the drum roll 1 extending element 4 in the transition zone between the drum 1 and the customer 2. This element 4 is used for air guidance in the diverging gap between drum 1 and customer 2.
  • EP-A-432430 is an adjustment device 4, which is below and along the drum roll 1 on the side of the customer 2 extends (cf. FIGS. 1, 2 of EP-A-432430).
  • the adjustment device comprises a baffle, also called a tongue, and has the task of guiding the air in the diverging gap, to optimally control between the reel and the customer.
  • a baffle also called a tongue
  • the tongue 4 has a foot part 6, which is fastened to a support 8 by means of screws is, which in turn is firmly connected to a machine frame part 9 at a foot end is.
  • the tongue is adjusted with screws 7, which are in slots 10 in the foot part 6 are performed.
  • EP-A-432430 is not concerned with the question of access to the screws 7. Because of the sheathing of the card, which is necessary for a modern Machine is essential, access to the parts to be adjusted is difficult and at least requires that the sheathing in the lower area of the drum beforehand must be removed.
  • an adjustment device is from the prior art according to FIGS. 3 and 4 known, which is built into the applicant's card C50.
  • the tongue 4 is on one End arranged on a so-called convertible top segment 14, this segment forms an element of the corresponding drum shield, as described in more detail below is explained with reference to FIG. 5.
  • the segments 14, each provided on one side of the card are used to carry roof elements, e.g. from US 5142742 or EP-A-431482 can be found.
  • the screw 30 comprises a first part 30A, which is screwed into a threaded bore in the leg 11 and with a locking nut is provided.
  • the part 30A serves as a bearing surface for the second part 30B, which is shown in FIG a threaded hole in the leg 12 is screwed.
  • Part 30B is used for Spreading the legs 11 and 12, which are designed to be elastically bendable.
  • Screw 40 serves as a fastening or clamping screw.
  • the tongue 4 is by means of a separate screw (not shown) on the lower leg 12 attached.
  • the gap A to be set is between the tongue 4 and the cylindrical surface 1A of the mounted on the drum (not shown) Set.
  • the adjustment with screw 30 causes a displacement of the lower one Leg 12 and thus also the tongue 4 with respect to the drum surface 1A.
  • the gap A in FIG. 4 is thus adjusted at one end. It's on the other end the tongue provided the same arrangement, so that the gap A below the Drum roll across the entire working width of the drum using the two adjustment devices can be adjusted.
  • screw 30B If screw 30B is screwed in too much, it creates plastic (permanent) deformation, which may no longer allow a correct setting. Furthermore, the Clamp screw 40 deform leg 12.

  • the arrangement can be made in this way that access from the outside of the drum shield is guaranteed.
  • the invention also enables a simplified assembly of the adjusting device.
  • Embodiments of the invention have the advantage that access to the adjusting screw is simplified because this is turned on by the drum shield. Likewise is fixing the setting e.g. simplified with a lock nut of the adjusting screw, because the mother can lie on the drum shield.
  • Tongue fixing screw i.e. to the screw, with which the tongue on the thigh attached, is simplified because this screw through an opening in the drum shield is easily accessible with a tool.
  • the invention also relates to an auxiliary means (a guide element) in a second aspect. for use in the transition zone drum / customer of a "cotton card", especially a revolving card.
  • auxiliary means for use in the transition zone drum / customer of a "cotton card", especially a revolving card.

  • the present invention is for use with an adjustment device according to the suitable in the first aspect, but is not limited to this.
  • EP-A-432430 is an aid for influencing the air flows "downstream" from the transition zone between the drum (also called drum) and known to the customer.
  • the arrangement was already based on FIGS. 1 and 2 described in more detail. A similar tool has already been used in practice it has been described with reference to FIGS. 3 and 4.

  • the element can be curved with a direction opposite to the air or fiber flow Surface, of which the curvature has a radius of no less than 4 mm (R4), preferably 6 to 10 mm (R6 to R10).
  • Said curved surface preferably flows smoothly into another curved surface Surface above that forms the outside of the guide element when viewed from the drum.

  • This tape is from one Tape storage 110 stored in cycloidal turns in a transport can 111.
  • the present invention is concerned with the design of the so-called "Sub-carding zone", i.e. with the drum section between the pickup roller 107 and the licker 103, and in particular with the transition zone drum / take-off roller. It is known that this transition is particularly delicate because can not be clearly predetermined whether a fiber on the drum with the Drum continues or detaches from it and combined with the removed fleece. As has already been explained with reference to FIGS. 1 to 4, it is therefore known To provide tools in the transition zone that are able to take the conditions in to influence the transition zone. It is important that the tool is adapted can be to adjust the ratios and that continuously during the Operation the set conditions over the entire working width of the transition zone (approx. 1 m) are observed.

  • the arrangement of the recess or anchoring rib is also in close to the licker-in (not shown in Fig. 7), so that the two fastening bolts 126 can be attached to the sign in the same way. Accordingly, the bolts 126 are very easily accessible for adjustment units without dismantling convertible top parts or the like.
  • the bow 14A is largely designed as a rigid structure.

  • the bow 14A has an end part in the Form of an elastically bendable arm 12A.
  • the arm 12A is initially with the same radius as the stiff part of the bend 14A, but subsequently bent inward (biased) such that a tongue carried by arm 12A would strike against surface 1A of the drum when attaching sheet 14A, if the countermeasures described below had not been taken.

  • the tongue is still at the end, i.e. on arm 12A attached to the bow.
  • the tongue could be fastened in principle using fasteners similar to the screw 40 in FIG. 4.
  • Such a solution would be but disadvantageous in combination with the new adjustment because it has some advantages of Adjustment itself does not have. There are therefore preferred solutions to the problem the tongue attachment are described below with reference to other figures.
  • the adjustment in the embodiment according to FIG. 9 thus differs from the arrangement 4 (i.e. according to the closest prior art) in that the upper leg 11 of the convertible top segment according to FIG. 4 has been omitted, so that the adjusting screw 32 (Fig. 9) with the shield (instead, according to Fig. 4, only with the Convertible top segment) works together. This has made it possible to use the screw 32 to perform through the edge portion 121 of the shield and it from the outside to make the shield accessible.
