Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an upright intermediate stand for a ring spinning machine, which secures horizontal longitudinal members such as a spindle rail and a draft mechanism with fasteners.
[0002]
[Prior art]
Draft mechanisms, spindle rails and other structural elements carried by the intermediate stand of this type depend, inter alia, on the tube length and also on the desired spinning geometry (spindle tip and feed roller). Should be mounted at different heights, depending on the spacing between the yarn feeder and the thread running angle between the yarn feed roller and the thread guide, and so on. In the case of a one-piece intermediate stand, therefore, a large number of dimensional variations are required, which make it difficult to machine different deformations, as well as storage and holding with cast material. .
[0003]
DE 39 21 274 already proposes an intermediate stand made of polymer concrete, in which a lateral traverse on which both spindle rails can be screwed is provided. , Are configured as separate members. The member can be screwed to the intermediate stand at different heights. The height of the receiving surface for the punching member for the draft mechanism, however, is fixedly preset. In addition, the intermediate stand further comprises a creel carrier, which again limits the variability of the intermediate stand.
[0004]
DE 37 20 631 discloses an intermediate stand formed as a sheet metal part, in which the transverse traverse housing the spindle rail is provided as a separate cast part. It is configured. Similarly, the draft mechanism carrier is configured as a separate member and is screwed to the intermediate stand, as in a transverse traverse. The mounting of these mounting members at different heights on the intermediate stand, however, is not performed.
[0005]
DE-A-43 19 959 discloses an intermediate protective plate for a spinning or twisting machine, which intermediate protective plate is formed as a one-piece cast protective plate. A traverse material such as a spindle rail, a cable passage or a rail, which is oriented in the longitudinal direction of the machine, is screwed to the intermediate protection plate. No possibility is provided for mounting longitudinal traverse members at different heights, for example in a transverse traverse which is transverse to the machine longitudinal direction and which can be screwed to an intermediate protection plate.
[0006]
DE-A 1 109 063 likewise shows an intermediate frame for a twisting or spinning machine, which is produced as a casting, on which all bearing elements are fixed. These bearings are used as bearings for components that are drawn through the entire machine. A height-adjustable lateral traverse is not provided for this.
[0007]
[Problems to be solved by the invention]
The object of the present invention is therefore to provide an intermediate stand to be manufactured from a casting in a reliable manner with one set of no more than three different components. , The desired spacing between the bottom surface, the spindle rail and the drafting mechanism at all predetermined spans is formed in a number of parts so as to be achievable.
[0008]
[Means for Solving the Problems]
This problem is solved by the features recited in the characterizing part of the main claim. On the threaded surface of the base of the intermediate stand for the holders, these holders and thus the spindle rail are fixed at a predetermined height. Without depending on this, the draft mechanism carrier, and thus also the draft mechanism, is fixed at the desired height on the screwing surface of the base of the intermediate stand for the draft mechanism carrier.
[0009]
Embodiments of the present invention are shown in the drawings, and embodiments of the present invention will be described in detail with reference to the drawings.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
As can be seen from FIGS. 1 and 2, the intermediate stand 1 according to the invention comprises a base body 2, a draft mechanism carrier 3 and two spindle rail holders 4.
[0011]
As can be seen in detail from FIG. 3, the substrate 2 has two legs 5 and two screwing plates 6 which are positioned perpendicular to the plane of the substrate. The substrate is advantageously manufactured as a cast part and has reinforcing ribs 7 on one side. The other side surface of the base is formed as a flat screwed surface 8. The outer surfaces 9 of the screwing plates 6 are flattened.
[0012]
The draft mechanism carrier 3 of FIG. 4 is advantageously manufactured as a cast member, as in the case of the base body 2, and has reinforcing ribs 7 on one side. The other side surface of the draft mechanism carrier is flat as the screwing surface 10. At the upper end of the draft mechanism carrier, the draft mechanism carrier 3 has bearings 11, in which a draft mechanism rod 14 that carries the stamping member 12 of the draft mechanism 13. It is stored. In the lower region, bearing angle members 15 are additionally formed, which bear the shaft 16 of the reciprocating roller 17 for the anti-ballooning ring and the moving thread guide, not shown here. Housings bearings.
[0013]
The spindle rail holder 4 of FIG. 5 comprises an anti-ballooning ring and a moving sled guide, and a guide bush 18 for the reciprocating rod of the ring rail. The bearing for the reciprocating roller 17 'of the tension belt for the ring rail is likewise fixed to this spindle rail holder. The casting of the holder 4 is arranged on its inner surface with a screwing surface 19 for precise abutment of the base 2 against the screwing plate 6 and for screwing the spindle rail 21. It has an outer threaded surface 20 and both surfaces are machined flat.
[0014]
All screwing surfaces 8, 9, 19 and 20 are provided with a number of perforations 22 or screw holes 23 for the penetration or screwing of the fixing screws. In this way, like the draft mechanism carrier 3 and thus the draft mechanism 13, the spindle rail holder 4, and also the spindle rail 21 via this spindle rail holder, are fixed at different heights on the base 2. It is thus possible to select their mutual spacing and height above the floor. Accordingly, FIG. 1 shows one intermediate stand 1, in which the spindle rail holder 4, like the draft mechanism carrier 3, is mounted at the height as small as possible. Above the floor, the height H1 of the spindle rail 21 and the height H2 of the yarn feed rollers of the drafting mechanism 13 and their mutual spacing are correspondingly so that this is to be achieved at the limit. Slightly. FIG. 2, on the other hand, shows one intermediate stand 1, in which the mounting members 3 and 4 of the base 2 have the greatest distance from the floor and from one another. . It is self-evident that the intermediate state of the two mounting members is also possible independently of one another.
[0015]
In particular, the screwing surfaces 8 and 10 in the base 2 or the draft mechanism carrier 3 have a large area. The perforations 22 and the screw holes 23 are provided, at least in these parts, on the side of the screwing surface, with peripheral ridges 24, so that the entire surface does not have to be flattened. However, it is processed flat independently. In the assembled state, then, in each case, only the peripherally raised ridges 24 which are machined flat are stacked.
[0016]
The construction according to the invention makes it possible to produce the three components of the intermediate stand 1, namely the base body 2, the draft mechanism carrier 3 and the spindle rail holder 4, always in the same specifications in an economical “stock” lot size. And allows for the assembly of differently sized intermediate stands from these components to the production part without waiting as needed.
