Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn path for a waste of a flat knitting machine as set forth in the preamble of claim 1, and to Patent V [Claim -12]
-Flat shape &i equipped with the thread guide mentioned in the preamble of scope item 19
Regarding machines.

In a flat knitting machine, the lower ends of multiple thread paths are made to touch each other on both sides of the needle bed, so that the lower ends of the thread paths are in contact with each other on both sides of the needle bed.
A problem arises when the thread path is also disturbed between needles in different knitting positions. The essence of another problem lies in the fact that the lower ends of the ICs must be provided with a thread ring in the thread path and pass by each other, while being partially in the same path of motion.

The known thread guide used in the past is composed of two parts: an upper part is fixed to the thread guide case, and a lower part (head) having a thread ring is moved by the lower part of the other thread guide. It is rotatably mounted on the top against the action of a compression spring so as to be deflected from the path. In this case, the lower part (head) is a forged part, and in the region of the forged part provided with the thread ring, both side edges extending obliquely in the plane of each other are approximately // It takes a relatively large angle of 45 degrees, reaching almost the height of the upper end of the thread ring, and then tapers at the upper part of the arm to provide a rotatable pivot (Germany). Industry standard shape A.

B, C). ′? J', that is, the end region of the lower part of the arm, which is approximately diamond-shaped and is provided with a thread ring, is constructed relatively wide to prevent the thread paths from coming into contact with each other. . This means that in the flat I machine, several knitted fabrics are knitted over the length of Kenpo, so that the intermediate space between the individual knitted fabrics in which the thread path has a turning point is as small as possible. This is particularly disadvantageous if the Other known yarn guide heads according to shape D of German Industrial Standard 62 161 do indeed have relatively sharply extending side edges and are relatively narrow. However, said lateral edges have significant drawbacks, which will be described below, in some areas even in the form of culms. In the known thread path C, the lower part of the arm that moves the thread ring to the right is made of a forged part in which the hole for the ring is made, and the lower part of the arm is relatively thick. It not only prevents them from meeting each other, but also causes problems when passing by each other. Furthermore, in the known thread path a3, two thread paths are
In a rotatable lower part with a thread ring, it occurs in certain situations that the shoulders of the thread convexes are pulled into each other, which results in serious damage to the thread path. This means, for example, that the lower part of one thread guide is deflected to such an extent that the lower part of another thread guide passes by and is hooked behind without covering, so that three thread guides can escape from an unfavorable situation at the same time. This applies when the beans must be allowed to pass by.

It is therefore an object of the present invention to provide yarn paths for a flat knitting machine in which the yarn paths can be brought closer to each other with less space requirements and, in particular, it is reliably guaranteed that they do not get caught in each other. Another object of the present invention is to provide a flat knitting machine equipped with the yarn path.

In the case of the yarn path for the flat knitting machine, the problem is as follows:
By the configuration described in the characteristic part of claim 1, and in the case of a flat knitting machine equipped with the yarn path, the configuration described in the characteristic part of claims 19-15- solved by.

The thread guide of the present invention is such that the lower part of the 77 arms of the thread guide always abuts against each other at the diagonal side edges, or only contacts the side edges, so that the slip of the side edges automatically causes the lower part of the arm to is deflected, so even when there is a maximum deflection and some thread paths pass each other on the opposite side, the thread paths do not catch each other, so that the thread path of the present invention does not catch with the horizontal thread path. Protected inwardly to have relatively good beveled side edges for mating. Said well-formed side edges are
It is possible to make the lower region with the thread ring relatively narrow overall, so that even less space is required. Furthermore, the thread guide arm is constructed in one piece and is spring-loaded in a flexible manner, so that said arm can also be constructed relatively thin, which means that the area of the thread loop is It also serves as a bond to reduce the thickness of the material as much as possible. For this reason, the thread guide can be manufactured more easily and at a lower cost since the rotatable pivot mechanism, which is costly, can be omitted.

In a preferred embodiment of the invention, the beveled side edges are 5°.
C extends into a very acute angle in the range ~15°, preferably 9°. However, in order to maintain the above-mentioned acute angle in the rotatably pivoted thread guide arm even in the swing a withdrawal state 1c, the above-mentioned angles are each increased by the rotation angle. This very sharp slope not only ensures that the thread guide arms are of elongated construction, but also that the thread guide arms can easily swing past each other even during deflection to the opposite side. This is even more true if the diagonal side edges are provided with a beveled surface, as is realized in other embodiments.

Even when using a knitting width maintaining wire, the thread guide arm may pass by the side without getting caught.
According to another embodiment, the beveled side edge at the free end of the thread guide arm is crossed by an additional bevel. The angle of the slope with respect to the longitudinal solid axis -17- is larger than the angle of the side edge, preferably 40°.

In the above-mentioned J: Uni, in the known thread guide, the lower part of the arm consists of a relatively thick forged part, and this forged part has wear resistance only as a whole by being hardened or coated. , which is incomplete. Accordingly, in a further embodiment of the invention, the lower end of the thread guide arm defines a downwardly open recess into which a separate insert with a thread ring is inserted. That is, the thread ring is realized as a special spigot, so that said spigot is made independently of the thread guide arm and can also be improved, especially with regard to wear resistance. In particular, the insertion part does not have to be applied to the entire thread guide arm, but can be simply and purpose-specifically hardened or coated with a hard coating in the area of the thread ring hole. . This is therefore very advantageous, since the operating conditions and the required material values in the thread guide arm are approximately 18-<18 mm above the above-mentioned insert with the thread ring.

In the known thread guide arm, a bulge on one side is stepped at the lower part of the arm, and a passage hole for a thread ring is disposed within this bulge. A disadvantage in this regard is that the thread ring hole is only accessible from one side of the lower part of the arm. In order to avoid this, in an embodiment of the present invention, the insertion part is made of a hollow lens-shaped element, the element has a passage hole extending in the vertical direction in the center, and the thickness of the insertion part is It's bigger than the arm.

In this case, for example, the depth of the U-shaped recess is greater than the corresponding height of the insertion part, and said T insertion part has one end approximately flush with the front edge of the thread guide arm, and the center It is inserted into the object regarding the part. Therefore, the thread can be passed through the thread ring-shaped hole through the remaining part of the recess.
The thread can be inserted into the hole in the thread ring from the front and back.

The insert can be accessed into the recess of the thread guide arm in a step-by-step manner, in particular by pinching or tightening. Furthermore, there is also the possibility of gluing or waxing the insertion part, and these latter connection steps are carried out by the curator,
Alternatively, it can be carried out independently of the tightening process.

Other Particulars and Structures of the Invention IJ1 The following detailed description describes and explains the invention in detail by way of illustrative embodiments.

In the illustrated flat knitting machine 10, the thread threaders 11-13 are arranged in a vertical line 14 of one bed 16, 17 of the front and back diagonally opposite each other.
are arranged closely adjacent to each other above.

The lower ends 19 of the yarn channels 11-13 with the yarn loops 18 are closely adjoined as described above, but this close adjacency also extends in the direction perpendicular to the vertical line 14 as well as in this vertical direction. It also occurs in the direction transverse to the line, so that, on the one hand, even if several knitted fabrics are adjacent to the needle bed, for example,
Attachment of the thread 3fi 11-13 (with little loss of intermediate space for the thread ring 18 of the threader 11-13)
All of the lower end parts 19 with . It has space.

Figure 1 shows the front and rear 11 beds 16.17, two]
J Mukari Tsuji 21, 22 and knitting width maintenance wire 34
In addition, in some illustrated embodiments three guide rails 23, 24 and 25 are shown, which are arranged parallel to each other.
It shows. Each of the guide rails has two guide paths 26 and 27. A yarn guide case 28 is disposed along the path so as to be movable in the longitudinal direction. A yarn channel 11-13 in each case is fastened to the case, for example by a screw 29, and the case can be moved synchronously with a cam carriage 21, 22 according to the respective selection during the knitting process. Move back and forth. Guide rail 23-
25 are arranged symmetrically with respect to the vertical line 14,
The thread guides IL-13 having different qualities are similarly arranged symmetrically. That is, the guide paths 26, 27 located on the outside of each of the outer guide rails 23 or 25 support the outer yarn path 11, and the -21- of the two outer guide rails 23 or 25 -21- of the other two guide paths 27.26 supports the central thread path 12, and the inner guide rail 24 supports the two guide paths 26.
．． At 27, the inner thread path 13 is supported and covered.

In FIGS. 2 to 5, thread paths 11.12 or 13 integral arms A31.33.32.33 are shown.
They differ, in principle, only in the warp, but all the nodes have the same end which receives, in each case, the same thread T'R18 at the free end 19. The thread guide arms 31-33 therefore all occupy essentially the same position above the needle beds 16, 17 with their lower ends 19, so that the overall lengths of these arms 18 also differ. The thread guide arms 31 to 33 in total are symmetrical with respect to their own longitudinal axis, and consist of an upper arm 37 having a hole 41, a central arm 38, a lower arm 39, etc., and the lower part 39 is , the receptacle for the thread ring 18 is provided with a conically extending end region 36 having four sections 42 for insertion.

As shown in FIG. 2, in the arm 31 of the outer thread path 11, the arm center part 38 is 7.
It is bent by an angle of 15 degrees, and the lower part 39 of the h1 node is bent at an angle of 27 degrees with respect to the arm center part 38.
bent at an angle or in the opposite direction.

In this embodiment, the longitudinal τ1 method is such that the arm upper part 37 is somewhat longer than the arm central part 38, and furthermore, the arm lower part 39 is configured to be slightly better. has been done. In J3 in FIG. 5, the arm 33 of the inner thread path 13 also has two opposite bent portions 43.
．． 44 to the right 5, the angle between the upper and lower arm parts 37.38 is 12.5°, and the upper center arm part 3
The angle 1 m between 8.39 and 39 is 5.5°. in this case,
The length relationship is such that the arm center part 38 is somewhat longer than the arm upper part 37, and the length of the lower part 39 of the arm 18 is shorter than the length of the arm upper part. In FIG. 4, the arm 32 of the central thread path 12 is provided with only an upper bend 43, and the upper and central portions 37.
38 together form an angle of 18°.

In this case, the length relationship is the middle part and the lower arm part 3
8.39 is constructed so that the total length of the arm 37 is twice the length of the upper arm 37.

-23- Regarding the overall length, it is obvious that the inner thread J arm 33 is shorter than the central thread guide arm 32, and furthermore, the thread guide arm 32 is -b shorter than the outer thread guide arm 31.

The thread paths A to 1131 to 33 are constructed in the shape of a bullet-like spring, and in this embodiment, a hard band-shaped spring steel J:
is formed. The thread guide arm has substantially parallel edges in the region of the arm upper part 37 and the arm central part 38, while in the end region 36 of the arm lower part 39 two diagonally opposite side edges 4G, 47 is tiered. These side edges 46, 47 are connected to the thread guide arm 31.
It is symmetrical about the solid longitudinal axis of the lower arm 39 and widens at the upper end of the lower arm 39. The side edges 46.degree. 47 approach the free end 19. That is, the end region 36 is tapered such that in this embodiment (FIG. 3) a'3 the lower end 19 is equal to the width of the two arm portions 37, 38, or It has a somewhat smaller width. Both side edges 46 and 47 are, respectively,
The -24- longitudinal direction of the thread guide arms 31-33 forms an acute angle with respect to the solid shaft 48. When the thread guide arms 31 to 33 are fixed to the thread guide case 28, this angle is between 5° and 15°, preferably 9°C. 46.47 has slope 4 along the entire length of the wall and on both the front and back sides.
It has 9.

In FIG. 11, if only one thread guide arm (31') is shown in the thread guide case 28' for reasons of knitting technology so as to be rotatable on both sides, The angle increases by the rotation angle on each side. In this case, the thread guide arm 31' is connected to the thread guide case 28.
' is rotatable about an axis of rotation 66 disposed at the other end and is provided with a pin 67 at the other end, which pin can be inserted into the recess 68 of the adjusting slide 69 and at the same time out of the three notches 70. engage one of the The notch is connected to the latch 7
1 , the free end of the latch 71 is connected to a tension spring 72 . The rotational positions depicted in FIG. 11 with dash-dot and dotted lines are obtained by the drive poles 1 to 73, which also serve to drive the case 28', at the relevant turning points of the yarn path.

Illustrated thread paths 11 to 13 (also 11' in Fig. 11)
In the end region 3 with beveled side edges 46,47
6 forms a significant part of the overall length of the thread guide arms 31-33 and occupies most of the length of the lower arm 39. Second
In the illustrated thread path 11, the terminal S: region 36 is somewhat shorter than the arm lower part 39. On the other hand, in the thread path 13 of FIG. 5, the length of the end region 36 is approximately equal to the length of the lower arm portion 39. In other words, the lower bent portion 44 forms the diagonal side edge 4
6.47 is in the upper end area. In the thread path 12 of FIG. 4, the length of the terminal region 36 is somewhat smaller than half of the entire length of the arm center portion and the arm lower portion 38, 39, and is approximately 1/1/2 of the total length of the arms 31 to 33. It is 4 to 1/3.

As can be seen in FIG. 6, the end region 36 of the lower arm 39 is provided with a recess 42 for receiving the thread ring 18. The recess 42 is U-shaped and has a lower end 19.
The side thereof is open and has a side edge portion 51 extending wedge-shaped in the thickness direction.

= 26 - Figures 7 and 8 show a thread ring 18 formed from a substantially biconvex non-shaped element 52. The lenticular element 52 consists of a precision casting and is flattened or sheared on all four sides, resulting in:
The cross section is almost square. A passage hole 53 is provided in the center of the thread ring 18, and grooves 54 or 56 are provided parallel to this hole on the two longitudinal sides.

The oval tapers from the outside to the inside in accordance with the wedge shape of the side edge 51 of the recess 42 of the termination region 36. At the bottom of one of the grooves 54, a substantially triangular protrusion 57 is provided at the center in the vertical direction.

The protrusion 57 has a notch 5 in the side edge 51 of the recess 42.
8 corresponds. In this case, in this embodiment, the notch 5
8 is provided on both side edge portions 51;
The protrusion 57 is disposed in only one groove 54 of the thread ring 18.

FIG. 9 shows an enlarged view of the symmetrical installation of the lenticular element 52 of the thread ring 18 in the recess 42 of the end region 36 of the thread guide arm 31, 32 or 33.

= 27 - The protrusion 57 engages with one of the notches 58 of the recess 42 C
The lenticular element 52 is moved into the recess 42 and the thread ring 18
(jj 4) is carried out. In the above state, the thread associated with the upper end of the lenticular element 52) d-arm 31,
The lower ends 19 of 32 and 33 are at the same height. Since the recess 42 is longer than the corresponding length of the lenticular element 52, a space 59 exists between the inner end of the lenticular element 52 and the inwardly bent end of the recess 42. , the lower end of this space 59 is connected to the passage hole 53 (see FIG. 3). That is, the passage hole 53 of the thread ring 18 can be reached from both the front side and the back side of the terminal end area 36 of the thread guide arms 31 to 33.

As can be deduced from FIG. 9, the lenticular element 52 ends on the sides in the area where the cut surfaces of the side edges 46, 47 begin, and in its central thickest part 6 its thickness is relatively It is small. In other words, the thread paths 11 to 13 are relatively wide in the region of the thread ring 18. Due to the lens-like curvature of the thread ring 18, the side edges 46 and 47 are removed.
One corresponding protrusion of the slope 9 is generated.

-28- As shown here, the lenticular element 52 is attached to the thread guide arm 3.
1-33 can be held in the recess 42 only by form-fitting. Instead of mounting using a form-fitting connection, it is also possible to use a frictional connection. That is, the lenticular element 52 can be inserted into the recess 42 .

In addition to the above-mentioned attachment, the lenticular element 52 can also be attached to the thread guide arm 3.
It may be attached to the terminal area 36 of 1 to 33 by adhesion or brazing. Lens-like element 52 or thread ring 1
8 is an independent element that is inserted after the production of the yarn channels 11-13 and can therefore be configured as required. As previously mentioned, the lenticular element 52 is threaded and is therefore a highly wearable part and therefore constitutes an M hard casting which is preferably hardened following the casting process. It is also possible to provide the thread ring 18 with a hard coating, for example a ceramic coating, or to insert a ceramic insert in the area of the passage hole 53. If the thread ring 18, which is configured as an insertion part as described above, is simply inserted, the part 29 can be used as a replacement part. That is, if the wear is significant, it can be replaced.

What is important in each case here is that the lenticular element 52, which is configured as an insertion part of the thread ring 18,
The thread guide arms 31 to 33 can be manufactured, processed and heat-treated in different ways according to different requirements.

FIG. 10 shows a modification of the lower end region 36' of one thread guide arm (for example 31).

The free end 19 is not provided with additional bevels 61 , 62 on both sides, starting from the region of the end of the associated side edges of the recess 42 and extending towards the longitudinal solid axis 48 . 4G, 47, or intersects with or takes over the side edges 4G, 47. Furthermore, the inserted lens 52 is also cut in this area by the bevel 61, 62. The slope 61
．． 62 is a knitting width holding wire 34 between both needle beds 16° and 17.
(Fig. 1), the thread guide arm with the thread ring 18 or the lower terminal area 36' (head) with these thread rings.
However, it does not attract the knitting width holding wire 34 (helps it pass through it).

As estimated from FIG. 1, the thread guide arm 31-3
It is possible to bring the lower ends 19 with thread loops 18 of J. It is possible to move by passing by. Thread path arm 31
.about.33 are formed in strips of spring steel so that the arms are deflected as they pass by each other.

The mutually opposite deflections of the four beds 16, 17 in the direction perpendicular to the vertical line 14 result, on the one hand, in the obliquely extending side edges 46, 47, in the chamfered edges 49 of said side edges, and in said surfaces 49; C is caused by the subsequent lenticular curvature of element 52. For this purpose, the thickness of the lenticular element 52 is small and the corners of the side edges 46, 47! It helps that the true angle is acute, and these thicknesses and angles are
This allows the thread guide arms 31-33 to easily pass and deflect past each other. Of great importance in this case is also the said length of the end region 36 or of the side edges 46.47 of said region.

Said length is such that, during the maximum possible deflection of the thread guide arms 31 to 33, the two thread guide arms reach the end region 3 of said arms.
It is selected so that it contacts only the side edges 4G and 47 of G. In other words,! 7, in the two thread guide arms 31-33 passing by, the deflection is carried out only by one thread guide arm, and therefore not uniformly by the two arms, but by the third one. Even when passing between the two, the third thread guide arm contacts only the side edge 46, 47 of the terminal area 36 with the thread guide arm that is deflected to the maximum among the other two arms. As a result, further deflection of one or the used thread guide arm is facilitated by said third thread guide arm.

According to the invention, the above-mentioned movement conditions carried out by the three thread guide arms on one side are facilitated by the end region 36 being elongated and provided with curved and beveled side edges 46,47. Re-32-ru. Similarly, in some cases, it may be useful to provide an additional slope (62) for the yarn guide arm beside the knitting width holding wire 34.

Summary The upper end can be attached to the thread guide case (28), and the thread ring (
The lower end region (36) having a diameter of 18) is double-shaped in one or two places, having a tapered shape towards the free end by means of diagonal side edges (46, 47) opposite each other. Inverted (opposing) buckled arms (31-
