Definitions

  • the present invention relates to a disintegration device for an open-end spinning device with a housing, in the interior of which an opening roller and an insert receiving the opening roller are arranged, which has openings which are enclosed on all sides and which correspond to housing openings connecting the interior with other parts of the spinning device.
  • DE-OSs 2,423,241 and 2,448,585 also disclose thin-walled foils which are glued to the walls opposite the circumference of the opening roller. However, the adhesive bonds cannot be easily removed if necessary. In order to avoid the film sticking in, it is also known to stretch the film and fix it in the tensioned state in the housing (DE-OSs 2.819.060 and 2.911.158). This is done with the help of a clamping wedge (DE-OS 2.819.060) or a hardenable filling compound (DE-OS 2.911.158). In both cases, there is a small gap between the ends of the film, at which individual fibers, which could not separate from the opening roller in the area of the fiber feed channel, get caught and can collect.
  • the object of the present invention is therefore to create an insert for a dissolving device which does not have the disadvantages shown, but rather which economical to manufacture, space-saving and quickly replaceable.
  • the insert is pot-shaped with a recess in the bottom, which opens a bearing bore supporting the opening roller, the insert being associated with a fixing device securing its position relative to the housing. Since the insert is pot-shaped, it has no edges - with the exception of the technologically-related openings -, on which fibers could temporarily adhere. The risk of malfunctions caused thereby is thus eliminated.
  • the fixing device is provided which secures the relative position between the insert and the housing.
  • fibers in the area of the perforations which act on their edges act in a tangential direction on the insert and can cause the insert to twist.
  • the fixing device can be designed differently and, under certain circumstances, can be designed as a tight fit between housing and insert. A better fixation of the insert in the circumferential direction, however, can be achieved by a non-circular design of the housing interior.
  • a preferred and particularly economical The rotational fixation to be produced is achieved according to the invention in that the interior of the housing is circular, but that the bearing bore is surrounded by an annular shoulder, the outer contour of which has the same diameter as the recess in the bottom of the insert and is arranged eccentrically to the interior to the same extent .
  • This eccentric arrangement of the annular shoulder surrounding the bearing bore, on the outer contour of which the recess conforms, is also eccentrically secured in this solution with respect to the use of the insert.
  • the insert can be removed from the housing by hooking a tool into the openings in the insert.
  • a tool into the openings in the insert.
  • the insert has only a very low thickness. There is therefore a risk of the tool slipping. Therefore, according to a further embodiment of the subject matter of the invention, at least two bores are uniformly distributed in the end wall of the housing. These bores make it possible to act on the insert in order to eject the side facing away from the open side of the housing, wherein the even distribution of the two or more bores in the housing end wall prevents the insert from tilting during ejection.
  • These holes can also be used to secure the insert against rotation, in that, according to a further feature of the invention, at least two on the outside of the bottom of the housing according to the number of holes in the housing end wall Insert attached guide pins are provided which engage in the holes in the end wall of the housing when inserted in the housing. These guide pins can also serve to axially fix the insert, in that the insert pins extend to the housing side when inserted and have threads at least in their area outside the housing for receiving locknuts.
  • At least one positioning recess is provided on the circumference of the recess provided for the axis of the opening roller in the bottom of the insert. This positioning recess serves to hold the tool so that the insert is correctly positioned by appropriately orienting this tool.
  • a positioning cutout also enables the insert to be oriented precisely at an angle using a marking provided on the end face of the housing interior.
  • the insert is preferably seated with relatively small tolerances in the interior of the housing, so that it is avoided with certainty that the distances between the tips of the opening roller assembly and the inner wall of the insert change due to pendulum movements and thus create uncontrollable conditions in the area of the opening roller can.
  • Inserting the insert into the housing can be significantly improved here by a guide element which can be inserted into the insert and which has a contour corresponding to the interior of the housing and, according to the number of positioning recesses provided in the insert, one or more positioning projections on its end facing the floor, which By engaging in the positioning recess, the insert is held and secured in an angular position even when it is inserted into the interior of the housing.
  • the insertable guide element in alignment with the recess provided in the insert and the bearing bore provided in the housing preferably has a bore adapted to this recess and this bearing bore to receive an insert pulling device or a insert ejecting device.
  • Such devices significantly simplify the insertion of the insert into the housing or the ejection of the insert from the housing.
  • the insert ejection device has an insert ejection element which is guided in the bearing bore of the housing and has bolts which can be brought into effect through the bores provided in the end face of the housing are.
  • the insert ejection device has a support device which is supported outside the interior on the open side of the housing and surrounds a space which is sufficient to completely accommodate the guide element.
  • the insert ejection device also has a cylindrical section guiding the guide element and a section with a reduced diameter compared to this section with an external thread for receiving the insert ejection element having a smooth bore and an adjusting nut supported on the insert ejection element on the side facing away from the housing.
  • the insert ejection device is fixed in the axial direction with respect to the housing by the supporting device, so that the insert ejection element with its bolts is brought into contact with the bottom of the insert by pressing the adjusting nut and is pressed out of the interior of the housing.
  • the depth of the bearing bore is greater than the depth of the interior of the housing and that the insert pulling device essentially consists of a bolt with three different sections graded in diameter.
  • the first section is larger than the bore of the guide element and serves to support the Emergency pull device on the guide element.
  • the second section corresponds to the diameter of the bore in the guide element and extends at the beginning of the insertion of the insert with the guide element located therein into the bearing bore of the housing.
  • the third section which has the smallest diameter, has an external thread for receiving a support washer, which is supported on the outside of the housing, and an adjusting nut, this section extending to the outside of the housing at the start of inserting the insert and at fully in insert inserted into the interior of the housing extends into the bearing bore of the housing.
  • the middle section serves to guide the insert pulling device, while the adjusting nut pulls the guide element with the insert into the interior of the housing when tightening with the aid of the support disk.
  • the insert is deformed by the guide element so that it takes on the exact shape of the interior of the housing.
  • the insert due to the stresses generated during use, the insert with the side edge of its openings will get stuck on the front edge of the housing interior and thus lead to damage to the insert.
  • the interior of the housing is damaged, since this is usually made of a zinc or aluminum alloy, which is known to be relative are soft compared to other metals.
  • the interior of the housing is surrounded on its open end face by a centering shoulder to support a guide ring of great hardness which can be fitted here, the width of which essentially corresponds to the depth of the insert and the inner contour of which faces the housing Side corresponds to the contour of the interior of the housing, while it widens slightly on its side facing away from the housing.
  • the extension preferably transitions without edges into the constant cross section facing the interior of the housing.
  • the guide element and / or the guide ring In order to enable correct angular orientation of the guide element and / or the guide ring in a simple manner, it is advantageous if these elements have a positioning aid on their side facing away from the bottom of the insert. Corresponding markings on these elements and on the housing are sufficient, for example.
  • a design of the subject matter of the invention is particularly expedient, in which the positioning aid is designed as cooperating guide surfaces on the guide element and / or on the guide ring and on the housing outside of its interior.
  • the guide surfaces as bolts and one of the bolts leading bore are formed, wherein the bolt is preferably arranged on the housing and serves to guide both the guide element and the guide ring.
  • FIG. 1 shows a housing 1 of a dissolving device, in the interior 10 of which during the operation a dissolving roller is shown, which is shown only by indicating its clothing tips 20.
  • This opening roller is in in a known manner, the sliver to be spun is fed with the aid of a delivery device 12, for which purpose a housing opening 13 connecting the interior 10 with the delivery device 12 is provided in the wall 11 surrounding the opening roller.
  • a further housing opening 14 is provided after the housing opening 13 in the fiber transport direction, which serves to separate dirt contained in the fiber material.
  • a third housing opening 15 is provided after this housing opening 14, to which a fiber feed channel 16 leading to the open-end spinning element (not shown) is connected.
  • the interior 10 has a circular shape.
  • the mentioned extended distance is achieved in that the axis 2 of the opening roller does not coincide with the center 17 of the interior 10, but is at a greater distance from the area in front of the housing opening 15.
  • the housing 1 which is usually a casting made of a non-ferrous metal, preferably in injection molding or Die casting process made of aluminum or zinc or an alloy with these metals as the main component, consists of a relatively soft material.
  • voids will be released which represent a fault in the fiber transport path and lead to faults in the yarn formation.
  • an insert 3 is therefore provided in the interior 10 of the housing 1.
  • This insert 3 consists of thin sheet metal and has a pot shape, which is produced by deep drawing, pressing or another plastic molding process.
  • 3 openings 30, 31 and 32 enclosed on all sides are provided in this insert. These openings 30, 31 and 32 in insert 3 are produced by punching from the inside out.
  • the insert 3 which has a peripheral wall 33 and a bottom 34 (see also FIGS. 3 and 4), has a recess 35 in its bottom 34, through which in the loading. drive state, the drive shaft of the opening roller is passed through.
  • This recess 35 can be of different sizes; the minimum size corresponds to the diameter of the drive shaft of the opening roller.
  • the recess can also be significant to be taller. Only such a large radial floor area should be provided that the insert 3 is given good rigidity and can be easily installed in the housing 1 or removed therefrom.
  • the axis of the opening roller and thus also its drive shaft is arranged eccentrically to the interior 10 of the housing 1.
  • the bearing bore 18 is surrounded by a concentric annular shoulder 180, which is thereby also arranged eccentrically to the interior 10.
  • This annular shoulder is only so small that it does not protrude from the bottom 34 in the direction of the opening roller when the insert 3 is inserted.
  • eccentric as this annular shoulder 180 is disposed to the interior space 10, also in diameter to the diameter of this annular shoulder 1 80 adapted recess 35 provided in the bottom 34 of the insert.

  • the housing 1 is provided with a marking in the area of the positioning recesses 4 and 40, as is shown in FIG. 1 in the area of the positioning recess 4.
  • the sliver fed to the opening roller via the delivery device 12 is dissolved in a manner known per se. Due to the peripheral surface of the insert 3, which has no interruptions apart from the technologically required openings 30, 31 and 32, thread accumulations and thus defects in the yarn and thread breaks are avoided.
  • the eccentric bearing of the opening roller relative to the interior 10 and the insert 3 fixes the insert 3 in its current rotational position without having to provide overly tight fits between insert 3 and housing 1.
  • This eccentric mounting of the opening roller is thus not only to be regarded as a passage opening for the drive shaft in a recess 35 whose diameter corresponds to that of the drive shaft of the opening roller, but also forms a fixing device with the annular shoulder 180 with regard to the rotational position of the insert 3.
  • the opening roller can also be concentric be arranged to the interior 10 and the rotational fixation of the insert can be achieved in that only the outer contour of the annular shoulder 180 is arranged eccentrically to the interior 10.

  • the fixation of the insert 3 in its current rotational position is done in this embodiment, however, by a non-circular design of the interior 10, the cross-sectional shape of the insert 3 is adapted. A change in the rotational position of the insert 3 is therefore not possible here either.
  • Fig. 2 shows that a single positioning recess 4 is sufficient for inserting the insert 3 at the correct angle.
  • Fig. 3 shows a further embodiment of the opening device with another possibility for rotationally fixing the insert 3.
  • the part of the housing 1, which contains the bearing bore 18 for receiving the drive shaft of the opening roller is extended to the rear.

  • the insert 3 used can be reliably prevented from rotating relative to the housing 1, even if the interior 10 of the housing 1 is round is and the insert 3 is arranged concentrically to this interior 10, ie if the extended distance between the opening roller and the wall 11 is dispensed with. For this it is not necessary that the bottom 34 of the insert 3 reaches up to the drive shaft of the opening roller, but it is sufficient if it reaches so far behind the opening roller that it gives the insert 3 the desired rigidity and the guide pins 43 and 44 can.
  • the guide pins 43 and 44 can have a length such that they extend through the bores 41 and 42 through to the outside of the housing 1 and at least on the partial area located outside the housing 1 has a thread 45 or 46, onto each of which a lock nut (not shown) can be screwed.
