Definitions
- the invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.
- opening rollers for open-end spinning machines are known for the purpose the replacement of the set are made in several parts.
- the set can consist of teeth or needles, which are applied to a clothing carrier are. This is, for example, in the form of a ring which applied to a base body of the opening roller and via a holder is held on the base body.
- the opening roller runs in an opening roller housing around.
- a sliver is placed in the opening roller housing are introduced and the fibers separated from it are fed via a fiber feed channel dissipated.
- Air balance in the opening roller housing plays a decisive role. It is for that required that the gap between the opening roller and opening roller housing are precisely adhered to.
- the set which is known to be subject to wear and tear, is subject to the conditions do not change in the opening roller housing.
- DE-A 25 28 485 shows an opening roller in which the ring-shaped clothing carrier non-positively via an elastic element in connection with a Holder for the clothing carrier is held on the base body.
- the elastic Element is applied by applying an axial force in the radial direction moves so that it rests on the inside of the ring-shaped clothing carrier and fixed it to the opening roller.
- the holder forms at least partially the front of the opening roller.
- the width of the opening roller is thereby set that the holder is designed to be adjustable in the axial direction. This is done, for example, by a thread on the base body, on which the Oats are screwed on directly, or by means of fastening elements, e.g. Screws.
- the elastic element allows that the holder even after the Lying on the elastic element remains axially adjustable until the desired opening roller width is set.
- Setting the opening roller width is done every time by measuring and adjusting the Delivery depth of the holder each time the set is replaced by the maintenance person. Then the holder must so that it does not adjust itself can, fixed by a securing element on the base body of the opening roller will.
- the setting of the width of the opening roller can be in the DE-A 25 28 485 shown execution very precisely, the width is independent of the axial extension of the clothing carrier.
- the setting the opening roller width is very complex and ultimately of the Quality of the work of the maintenance person dependent.
- an opening roller is known in which the clothing carrier is annular and has a holder on the opening roller is held.
- the axial width of the opening roller is determined by the width of the clothing carrier determined, since this with one of its end faces on the base body the opening roller rests, while on the other end of the Support the lid or oats axially on the clothing carrier.
- an opening roller is known in the holder and Tray carriers are formed in one piece, the truss carrier axially on Base body of the opening roller supports, and thereby the width of the opening roller specifies.
- the well-known opening rollers in which the set is replaceable, have the disadvantage that either the assembly of the opening roller is complex and the width of the opening roller must be readjusted, or that the Clothing carriers, since they determine the width of the opening roller, are particularly precise and therefore have to be manufactured at high cost. Nevertheless there is the problem that the width of the opening roller is still despite precise manufacture is not exactly determined, since the garment holder after the manufacture of some Embodiments is still coated, so that by material application the width of the clothing carrier in the coated version of the uncoated varies. Even with a very precise manufacture of the clothing carrier there is a problem that the width of the opening roller varies.
- the object of the present invention is to propose an opening roller, which avoids the disadvantages of the prior art and which with different designed, coated and untreated clothing carriers can be.
- This object is achieved by the features of claim 1 solved.
- the base body has an axial stop for the holder, the axial extent of the opening roller is determined regardless of that of the clothing carrier.
- the width of the clothing rack So it doesn't matter whether it is a clothing rack acts that is coated or not.
- different coatings or different basic materials from which the clothing carrier exist are irrelevant to the axial dimension of the opening roller.
- the assembly of the opening roller both the Initial assembly as well as assembly after replacing the set, essential is simplified since no measurements need to be made because the correct position of the holder results automatically.
- the base body and / or the holder has a shelf which radially engages over the clothing carrier.
- the board has an annular, axial groove, with which it is possible at the same time, the clothing carrier radially either to lead on its outer or inner diameter.
- the radial leadership allows the clothing carrier over the outer diameter of its edge in addition to the necessary guidance, there is also a minimal gap between Board and clothing rack. Board and clothing carrier are therefore practical radially without play against each other. This prevents fibers from getting caught.
- the clothing carrier on at least one of its Edges has a diameter increase with which he works with the board. This ensures that the parting line between the clothing carrier and board radially outwards, away from the lateral surface, where there are fewer fibers, so that they are particularly safely prevented can that fibers get stuck in the gap between the clothing carrier and the shelf can.
- the design with a groove on the clothing carrier is particularly favorable which the teeth are made of by grinding.
- By the Manufacturing process is an increase in diameter at the edge of the clothing carrier only possible to a limited extent.
- By training with a groove but can also in this Fall the parting line radially from the lateral surface of the clothing carrier be shifted outside, so that advantageous in this version of the Opening roller jamming of fibers can be prevented.
- the formation of the clothing carrier as a ring is particularly favorable because it is a particularly easy exchange of the set of the opening roller enables becomes.
- the axial extent of the edges of the ring is advantageously different trained, which signals the maintenance person when exchanging is how to properly mount the ring on the opening roller.
- This can also be advantageously achieved in that the inner and / or the outer diameter the ring is designed differently in the area of the edge, so that in connection with the design of the diameter of the board or the groove of the opening of the opening roller prevents incorrect installation can be prevented.
- the clothing carrier can advantageously be designed as a steel ring, since this is inexpensive, stable and versatile and can be used. It is It is advantageous that the steel ring is also designed in one piece with a set can be, which is advantageous by grinding in axial and radial, in Grooves aligned grooves is formed.
- the clothing carrier a ring made from an extruded profile. This will achieved that the ring manufactured inexpensively and in large numbers can be.
- the ring is advantageously made of an aluminum alloy.
- a particularly advantageous fixation of the clothing carrier when it is separated is formed by the holder takes place according to the invention with an elastic Element that fixes the clothing carrier radially to the inside diameter of the clothing carrier. It is advantageous to do this with a holder corresponding force applied to the deformation of the elastic Elements causes.
- the holder advantageously has an axial one Direction extending web, which, viewed in the axial direction, oblique Level.
- the Opening roller a base body, in which both fasteners for one are provided in one piece with the holder designed holder and at the same time fastening means or a fastening device for fastening a ring designed as a ring.
- both clothing carriers which are designed as a ring as well as those in one piece with a holder are formed, can be arranged on the same base body.
- This is particularly advantageous because it has many variants of clothing carriers the same body can be connected, which makes a special User-friendly, versatile and inexpensive opening roller manufactured can be provided with almost all possible trimmings in exchange can be.
- a Generic opening roller for an open-end spinning device has one or more openings that the Front end extend into the interior of the base body, and that the base body has a bore into which a bearing sleeve supports the opening roller reaches into and the bore inside the base body in diameter enlarged and extends axially into the opening to advantageously one for Cleaning the interior to create a continuous connection, so that dirt through the openings, e.g. by blowing in with compressed air can be. Dirt passing through the gap between the main body and the bearing sleeve has penetrated into the interior of the base body, can be removed easily and advantageously. After loosening the The openings are accessible to the clothing rack and accumulations of dirt easy to remove.
