Definitions
- the invention relates to a traversing thread guide for winding machines with an endless thread groove having a reverse thread shaft, with a body that is straight on two guide rails is guided back and forth on the one hand
- Thread guide carries and on the other hand one in the thread groove of the Reverse thread shaft protruding guide approach, and with a pivotally mounted on the base body and in the thread groove the shuttle thread engaging boat, the one in Compared to the height of the thread groove, the height is significantly lower having.
- Traversing thread guides are an integral part of Thread tails with a reversible thread shaft, especially high-speed thread tails.
- a traversing thread guide of the type described at the outset is out DE-OS 18 09 662 known.
- the traversing thread guide owns a base body, which is the largest width in two U-shaped trained guide grooves engage in guide rails, so that it is guided back and forth there.
- the basic body does not come with the outer diameter of the reverse thread shaft in contact.
- the base body carries the reverse thread shaft a thread guide into which the one to be laid ends Thread is hooked.
- the basic body of the traversing thread guide has a guiding approach that leads into the endless thread groove of the Reverse thread shaft protrudes. This leadership approach is one-sided eccentric to the radial to the reverse thread shaft extending axis of the base body of the traversing thread guide arranged.
- the guide approach has a height that is half Depth of the thread groove corresponds to the reverse thread shaft.
- the A shuttle is assigned to the main body of the traversing thread guide, which has a hull-like shape and itself about the other half height of the thread groove of the reverse thread shaft extends.
- This boat is also with its outer contour adapted to the width of the thread groove. It is eccentric arranged to the axis of the traversing thread guide, there being a Has axis of rotation, which is inserted into a bore of the base body is, so that the shuttle is opposite the Base body can twist as it interacts with its rotatingly driven reverse thread shaft required is.
- Both the shuttle and the leadership approach of the The traversing thread guide engages in the thread groove of the reverse thread shaft and lead on the side walls of this thread groove.
- Set the side walls of the thread groove of the reverse thread shaft not a flat surface, but a helical shape curved surface.
- a linear or flat contact between the guide approach of the base body and the shuttle on the one hand and the side walls of the thread groove on the other achieve is a complicated shape in these two addressed areas required.
- the pointed shape of the guide approach is based on the pitch of the thread groove the reverse thread shaft matched, so that such traversing thread guide only for a certain fixed slope of the Thread groove of a reverse thread shaft can be used.
- a traversing thread guide is known from DE 37 21 139 C2 consists of several parts. The division is between one Carriage and a boat body performed, the Shuttle body not only fills the height of the thread groove, but also has a bolt-like support, which engages in a corresponding hole in the carriage, so that at this point the swiveling outside of the thread groove The parts are connected.
- the sled itself owns U-shaped grooves engage in the guide rails so that the Traversing thread guide guided here back and forth in a straight line becomes.
- On the carrier of the shuttle body is a guide lug provided, which can have a cylindrical shape and into which Thread groove of the reverse thread shaft protrudes.
- the actual shuttle body is realized with head pieces, not only on the side walls of the thread groove, but also at the bottom of the thread groove.
- the headers can be designed to be resilient in relation to the guide attachment in order to Adaptation to the reversing radii at the reversal points of the thread groove to achieve.
- This known traversing thread guide has one relatively large mass, which at most reduces it can be that the bow-like tips of the boat-like Headpieces can be removed or omitted.
- the headers have to the flat system on the side wall and the A relatively complicated shape due to the thread groove exhibit.
- the head pieces forming the boat extend over the entire height of the thread groove.
- traversing thread guides known, in which the Basic body consists of a molded plastic part that with a thread guide designed as a ceramic part is firmly connected.
- the base body is provided with a guide pastille that forms two pairs of parallel guide surfaces to pivot of the base body at the reversal of the thread groove allow the reverse thread shaft relative to the guide rails.
- the basic body of the traversing thread guide is already here advantageous between the outer diameter of the reverse thread shaft and the guide rails. That assigned to the basic body
- the boat is corresponding to the cross section of the thread groove adjusted little game.
- This traverse guide already has a relatively lower mass, so that it for High-speed thread tails appear more suitable.
- the arrangement of the guide lozenge also requires again a certain size with appropriate mass.
- the invention is based, in particular for High speed thread tails suitable traversing thread guide to create a comparatively smaller and Lighter design enables and regardless of the slope the thread groove of the reverse thread shaft can be used.
- this is the case with a traversing thread guide described type achieved in that the leadership approach the base body has the shape of a cylindrical bolt, which is arranged coaxially to the axis of the base body and with little play is adapted to the cross-sectional shape of the thread groove, and that the boat is largely hollow and in an outer groove of the bolt is pivotally mounted.
- the invention is based on the idea of the functions of Individual parts of the traversing thread guide clearly from each other separate.
- the guiding approach of the base body is in the form of a cylindrical bolt realized, so its outer circumference is cylindrical and with little play of the cross-sectional shape the thread groove is adapted.
- the boat is the only part which pivots relative to the axis of the traversing thread guide executes as they go through the reversals the thread groove of the reverse thread shaft occurs.
- the mass of this The shuttle is kept optimally small, in that the height of the boat is only a fraction of the height of the Makes thread groove and the entire boat largely "hollow" is designed.
- the The boat consist of a bent wire part.
- the boat is in an external groove of the bolt pivotally inserted.
- the design of the revolving External groove on the pin is on the pivoting bearing of the boat matched to the bolt.
- the training can also be taken so that the boat in the area of Outer groove of the bolt by a small amount compared to the outer diameter of the bolt protrudes, so that even in this area the boat takes on leadership function and through leadership points the linear support of the bolt on the Side walls of the thread groove replaced.
- the shuttle of the traversing thread guide can at least in the Contact areas to the side walls of the thread groove below Training of leadership points should be rounded off. With that the desired point contact system reached and the screw-like curvature of the side walls of the thread groove optimally taken into account. The boat itself receives one optimally low mass.
- the basic body of the traversing thread guide can be between the Outside diameter of the reverse thread shaft and the guide rails have its greatest width and in the direction of the thread guide wear a strip-shaped approach that is only two parallel guide surfaces for contact with the guide rails forms.
- the boat should be symmetrical to the axis of the body be formed or at least four symmetrical to the axis of the base body have arranged guide points. This results in good guidance of the boat in the thread groove of the Reverse thread shaft, and it doesn't matter whether the shuttle is at its use in the reverse thread shaft pivoted by 180 ° is introduced or not.
- the boat can be crowned Have an outer contour. This training is particularly useful around the boat relatively regardless of the size of the turning radii to make the reverse thread shaft. With different Reverse thread shafts with different turning radii are formed the guide points only on this spherical outer contour different places.
- the base body can be hollow. This contributes to one further weight reduction without the swiveling Storage of the boat on the bolt of the base body in is adversely affected.
- the traversing thread guide 1 has a base body 2 which is preferably produced as a molded plastic part.
- the actual thread guide 3 which is preferably is designed as a ceramic molded part and in particular 2 apparent form, embedded or with the base body 2 firmly connected.
- the base body 2 has in its central part has a collar 4 in which the base body 2 has its greatest width (Fig. 1).
- the traversing thread guide 1 is between two guide rails 5 and 6 on the one hand and the Outside diameter 7 of the reverse thread shaft 8 out, so that be Center of gravity as close as possible to the reverse thread shaft 8 is. Conversely, this results in a low overall height the correspondingly low weight.
- the base body 2 has two guide surfaces 9 and 10, with the help of which it is straight guided back and forth on the guide rails 5 and 6 is. Because here one pastille is avoided and only two parallel guide surfaces 9 and 10 must be accommodated, the traversing thread guide 1 has a relatively small overall length (Figs. 2 and 6).
- the collar 4 can as a disc (Fig. 6) around Axis 11 or as a rectangular limited plate-like Be formed body.
- the weight of the traversing thread guide To keep 1 small is a round disc-like Design.
- the base body 2 of the traversing thread guide 1 has a guide shoulder 12 in the form of a cylindrical bolt 13, with which he has at least over a large part of the height of the thread groove 14 protrudes into this, preferably without the bottom of the thread groove 14 to touch. But it is also possible to the bolt 13 as long shape that he deliberately touches the groove bottom of the thread groove 14, so that the contact of the federal government 4 with the outer diameter 7 Reverse thread shaft 8 is not required.
- Base body 2 and the bolt 13 may be hollow, that is with be provided with a recess 15, as shown in dashed lines Lines are indicated in Fig. 2.
- the guide lug 12 or bolt 13 has an outer groove 16, in which a shuttle 17 is rotatably supported per se, although the shuttle 17, when the reversing threaded shaft 8 is driven, only executes a pivoting movement corresponding to the pitch of the threaded groove 14 about the axis 11.
- the boat 17 can be designed as a wire bracket 18 (Fig. 3) with the apparent shape.
- This wire bracket 18 has a circular cross-section and the shape shown in FIG. 3, so that guide points 19, 20, 21, 22 are formed on each side of the wire bracket 18, on which the shuttle 17 has point contact with each side wall of the thread groove 14 , depending on the positive or negative pitch of the thread groove 14.
- the shape of the wire bracket 18 is such that, as can be seen, the reversal points of the thread groove 14 can be traversed without the risk of pinching. This also applies to those thread grooves 14 which have a constant width even in the area of the reversal points. From Fig. 1 it can be seen in particular that the shuttle 17 has only a very small height compared to the height of the thread groove 14. The height of the boat 17 may be in the range from 1/5 and 1 / 10th of the height of the thread groove fourteenth
- FIG. 4 Another embodiment of the shuttle 17 as a molded part 23 shows Fig. 4.
- This molded part 23 is made of spring steel sheet, similar to a circlip according to DIN 471. Both the Wire bracket 18 as well as the molded part 23 can be snapped on can be inserted into the outer groove 16 of the bolt 13.
- FIG. 5 shows a further embodiment of the shuttle 17 with spherical outer contour 24, the radius of which is less than or equal to Reverse radii of the reverse thread shaft 8 is formed. Consequently the reversal points arise in different positions each according to the reverse radii used. This is for the lead point 20 illustrated by the double arrow 25.
- FIG. 7 shows an embodiment in which three boats 17 in three outer grooves 16 spaced apart and thus separated pivotable to each other on the bolt 13 of the base body 2 of the Traversing thread guide 1 are stored. Since the side walls of the Threaded groove 14 represent a curved surface, the Shuttle 17 in contact with the side wall in the thread groove 14 rotated at a slight angle to each other about the axis 11 set and thus different guide points 19, 20 or 21, 22 form. So there is an adaptation to this curved surface by the shuttle 17 automatically and without special processing.
