Description

One of the oldest basic inventions of humanity is the fabric production from woven threads as woven and knitted fabric. Thousands of years ago, a pre-stage machine-building machine could be used with a loom, because the construction consisted mainly of wooden parts. The mechanized mesh production, however, required fine elements on which the last formed meshes develop. These elements mentioned elements could only be made of metal, so that their development can be seen as state of the art in metalworking. In 1589, for the first time, hook needles, also called spikes or knitting needles, were created, the reed pin in 1856 and the needle at the beginning of the 20th century.

In particular, it was the latch needle, which prevailed dominant for the mass production of knitted fabrics, the prerequisite for this was hardenable steel, which could be produced only in the required quality from the middle of the 19th century. With this technology, it is an advantage that the thread inevitably takes over a control task by the movement of the tongue during the stitching and thereby - apart from patterning effects - only one control foot must be provided on the needle. In addition, the latch needle is designed as a ready-to-use functional unit that can easily be used and exchanged by the operator in the machine. With increasing increases in rotational speeds in circular knitting machines and simultaneous multiplication of the knitting systems, however, the described advantage proves to be a weak point for production safety. Therefore, intensive considerations have been made to find new ways to eliminate the storage-related disadvantages of the tongue. In this case, found as an alternative to the reed needle technology two-piece knitting elements in which the thread by means of the hook part of a knitting needle or needle each held by the held at the tip of the complementary mesh as Loop is moved through and forms a new stitch, wherein the old mesh is dropped over the head of the needle. Thus, for special applications, for example in warp knitting machines with the extremely short cycle times, this type of needle could already prevail. The disadvantage of this technology in knitting machines, however, is that for each element a special control track is necessary for its control foot, which must be accommodated in each case in the lock systems. For the double-surface application with the cramped lock constructions there is an additional problem.

From the publication DE 2241769 A Two-part knitting elements are known which provide both the phased holding of the slide by a retaining cam and the stopping by braking action in the needle channel. For the implementation but a considerable length of the slide member is necessary to accommodate the stops for the relative movement of the slider to the needle. The handling in practice for inserting the slider in the machine requires a manageable length of this component. The two-part solution was too complicated for general use and therefore could not prevail in the many decades against the latch needle.

The in the published patent application DE 2245731 A Although described embodiment comes without retaining cams on the slide part, which was already anticipated by the former publication, this solution does not come into consideration because of the disadvantages of the heating due to the braking effect of the slide for heavy duty machines.

The common technology of stitch formation with latch needles builds on a development period of more than one hundred years with a multitude of different machine types. To use the advantage of tongue-free meshing elements for the various applications with high-performance machines, there is not so much development time with correspondingly large design effort as before available. The correspondingly short development time complicates the rapid introduction of this technique on a broad basis.

The object of the invention characterized in claim 1 is to provide a knitting or warp knitting machine in which the advantages of the latch needles technology can be exploited as a functional unit with the advantages of the slide needles. In this case, the disadvantage of an extra controlled complementary element to be used in user-friendly size in the machine to be avoided.

According to the invention of claim 1 there is a fourth needle category to be referred to as a swinging link needle, in which the long shaft of the slide element is transformed into a mini-link link reciprocating within the needle. This is moved in phases along with the needle on the one hand and controlled on the other hand by the machine, stopped in phases. From the point of view of implementation, the longitudinal guide is always more complex than the fulcrum bearing of a component. With conventional design models, this would be here as well: the board should have a leadership approach and be secured with tongue and groove laterally against falling out of the needle shaft smoothly, which limits the fineness of execution in addition to these difficulties in mass production. The smaller the board should be, the more complex it is to find a solution suitable for mass production. However, it would be desirable because of the approximation of the movement from the holding state to the movement phase, an approximately massless execution of the vibrating element. The invention simplifies the problematic longitudinal storage with the smallest size in that between the vibrating member and the needle body, a central connecting bracket is provided, which ensures both the relative movement of the oscillating member to the needle body and its lateral guidance, as well as on the sliding surface in the needle , In this way, analogous to the up and zuschwenkenden tongue back and forth in the needle mini-circuit board member realized with the important Difference, not by the thread, but to be controlled by the machine. The precision of the execution does not demand the highest standards, since the accuracy in the machine after insertion of the needle is given in this of the needle channels and the lock system. From this, a new needle-making technology can be derived with new machine design possibilities that allow the required precision to be achieved with less specialized technology. In comparison to the production and installation of the tongue with latch needles, this simplifies drastically, because instead of the complicated design of the tongue with different zones and the transition from the flat stem to the spoon-like tongue head occurs only a simple structured swinging member. In this case, the connecting bracket corresponds in its function to the axis in a latch needle in order to transform the pivoting movement of the tongue into a rectilinear oscillating movement of the miniature member. Complex operations are eliminated and the assembly to the functional unit can replace the high technology of complex manufacturing and assembly machines with much cheaper device or manual work with the necessary precision. The inventive conception of the vibrating link needle allows machine designs based on latch needles with only one lock track, wherein the relative movement of the vibrating member to the needle as go and stop function by means of two holding balconies acting on a stop tooth on the vibrating member or by braking action in the needle channels on the vibrating member he follows. The previously coordinated second control track is eliminated. Here even a needle movement corresponding self-control of the vibrating member is possible. In warp knitting machines, in which the complementary parts must be moved in phase at a high speed in a second ingot, this advantage becomes particularly clear.

In this way, the design effort for the variety of applications can be significantly reduced. It can be based on the same castle designs with smaller ways as in the numerous tongue-needle knitting machines. The application for the dihedral Fabric production with additional dial is also suitable because of the short length.

Although they are from the DE 2950147 A1 describes two-part knitting elements which are perpendicular to the needles movable and tilted parallel thereto. However, these must be arranged in a special outer ring around the needle cylinder in associated slots and inserted in each case to each needle. In this way it is not possible to realize functional units consisting of needle and transmission element.

Also at the DE 4446952 A1 it is a slider needle, with the aim of doing the case while the needle-separate control of the slider, as in a latch needle by means of the thread. The structure of this complicated unit but is unstable with the slots provided in the side walls and the guide pins therein and not suitable for production fineness. In addition, in high performance machines it should be avoided to stress the yarn for stitching control tasks, ie these tasks should be done by the machine.

Essential for the solution of the object according to the invention, however, mesh forming elements, in each of which a controllable by the machine Miniplatinenglied is integrated.

The inventions are basically applicable to all machine variants advantageous. They offer versatile patterning possibilities, especially for the finest pitches and lowest mesh heights with the goal of strong knit fabrics.

Fig. 1 shows a side view and front view of the swing member 11 of the functional unit vibrating member needle in the first embodiment with the highest rationalization effect and the largest range of applications. The front transfer section is adapted in its sliding area with the transfer tip 12 of the needle slot 4 and is delimited by a Trennungsnut 18 with stop edge 19 of the rear section, which is provided with a fastening gap 15 for the head 10 of the connecting bracket 8. The stop edge 19 of the separation groove 18 serves to limit the relative movement of the oscillating song in the needle body 1 to the front. For this purpose, a stop tooth 14 is provided on the oscillating member 11.

In the side view and top view according to Fig. 2 from the top of the central connecting bracket 8 is the with its open legs 9 in this Version movable in lateral guide recesses 7 connected to the needle body 1. His head 10 is clamped in a mounting gap 15 on the vibrating member 11.

According to Fig. 3 Contains the front part of the needle body 1 in a side view of the needle-typical features needle hook 2, 3 needle needle, needle slot 4 and a special feature a deposition with stop edges 5 and 6 behind the short needle breast. In addition, the lateral guide recesses 7 are indicated for the open legs 9 of the connecting bracket 8 in the needle shaft.

In Fig. 4 , A representation in side view and top view of the top of the swing member 11 with clamped connection bracket 8 in a pre-assembly, the whole front portion of the swing member is set to the slot width 4. The legs 9 have an outwardly acting spring bend 20, so that upon insertion of the functional unit in the needle channel a braking effect on the swing member 11 is formed, which allows the go and stop function without stop tooth 14.

According to Fig. 5 the oscillating member 11 is introduced with the preassembled connecting bracket 8 obliquely from above with its slightly spread leg ends 9 on the needle shaft and then moved back so that the legs in the guide recesses 7. Here, the simple basic structure and the easy assembly of the functional unit swing link needle is demonstrated.

In Fig. 6 is shown in side view and top view from above a section through the attachment zone or sliding zone of the guide recesses 7.

FIGS. 7 and 8 show in side views the ability to produce the guide grooves 7 on the needle body 1 without cutting by an embossing process. In this case, a gap 17 is provided with subsequent breakthrough on the guide width 7 instead of the guide recesses 7, in such a way that the lateral guide recesses 7 are impressed with two counter-acting punches, wherein the gap 17 is reduced by the material displacement, as in Fig. 8 is apparent.

Fig. 9 to 13 show schematic representations of stitch formation in a section through the needle channel with additional action of the knitting machine in the forward and backward movement of the functional unit swing link needle. The recorded in the balcony sockets 25 holding balconies 26 allow the go and stop function of the swing member 11, the stop tooth 14 has space in an annular recess 23 in the knitting lock. In this case, Z is a section through a needle channel with the oscillating link needle 1 located therein and S denotes the section of one of the rows of stitched knitting systems on the cylinder jacket surface. When a needle passes through the knitting system, the following functions result.

In Fig. 9 the needle 1 is in the inlet zone of the knitting system. The last stitch is held over the needle breast 3 with the transfer point 12 located therein in Austriebsstellung, ie the swing member 11 is in the rear position and a new thread is inserted into the needle hook 2. The holding balcony 26 is with its upper edge below and at the beginning in the direction of rotation of the stop tooth 14th

During the further rotation of the cylinder in Fig. 10 the needle 1 was withdrawn. In this case, the oscillating member 11 was stopped by sliding along the stop tooth 14 on the holding balcony top edge 26, so that in this phase of the retraction, the last stitch on the transfer tip 12 passes and thereby the new thread is included.

Fig. 11 shows a state in which upon further withdrawal of the needle from Figure 10 to fig.11 no holding balcony was present, so that the needle 1 moves together with the frontmost swing member 11 in the Kulierstellung. During this process, the old stitch is thrown off the transfer point 12, leaving a new stitch in the now Needle hook 2 hangs. Before the movement reversal forward, the stop tooth 14 is already below the second holding balcony 26 in the knitting system.

Fig. 12 shows the state in which in the forward movement of the needle 1 of fig.11 to Figure 12 the oscillating member 11 has been stopped at the bottom of the next balcony 26 by means of its stop tooth 14 and the transfer point 12 has opened the needle hook 2, that is, it returns to the needle breast 3.

Fig. 13 shows the final phase, ie the state of Figure 12 to Figure 13 , in which no holding balcony 26 is more available, ie needle 1 and swing member 11 come together in the Austriebsstellung. There is no holding balcony 26 between the outlet zone and the inlet zone in the next knitting system. The stop tooth 14 re-enters the next knitting system above its first holding balcony 26.

Between the representations according to FIGS. 12 and 13 There is also the possibility with the same selection technique as with tongue needles, to make Fangmaschen. This is also a particular needle 1 is not like Fig. 9 shows fully, but only expelled so far that the stop tooth 14 is below the support bar 26. In the subsequent return movement of the needle 1 together with the oscillating member 11, the transfer tip 12 remains in the needle breast 3, so that the mesh located there again enters the needle hook 2, in which a new thread has already been captured.

In the illustration according to Fig. 14 , the side view and the front of the needle hook 2, here in 10-fold magnification, was dispensed with the usual round reduction of the needle hook, ie this has the full shaft thickness of the needle 1, and the transfer tip 12 is not as usual above, but in the needle hook 2 immersed in a hook notch 24. In this way, lower mesh heights can be achieved by 0.3 mm and fabricates almost as firm as woven fabric. To make room for the thread create during the Kuliervorganges, you can provide 2 crescent-shaped indentations 27 in the middle of the needle hook.

In Fig. 15 the inner working parts of the knitting system are shown on a fairly natural scale. Therein, the balcony sockets 25 are provided at the same height when the holding balconies 26 are taken off-center as a narrow elastic member in the balcony sockets 25. In this scale, the control track F for the needle feet is visible.

Fig. 16 shows the relationship of the holding balconies 26 to the arrangement of the stop tooth 14 on the vibrating member 11 in a tenfold magnification. The relative movement of the oscillating member 11 to the needle 1 is denoted by a, while the joint movement of the needle 1 with the vibrating member 11 has been determined as b. The width of the stop tooth 14 thus results with b / 2 and the eccentricity of the holding upper edge of the balcony 26 in the balcony frame 25 with b / 4.

The variant according to loud Fig. 17 shows in a compact design for the finest needle thicknesses in a side view and top view of the swing member 11. In this case, the swing member 11 goes over with its rear boundary in a guide finger 28 having lateral deposits 29 in the connection bracket thickness, Fig. 18 in the same views the connecting bracket 8, which is clamped in this embodiment instead of the guide recesses 7 fixed in a mounting opening 7 in the needle body 1 Fig. 19 ,

The pre-assembly of the connecting bracket 8 in the needle body 1 is carried out according to Fig. 19 ,

The swing member 11 in Fig. 20 is, as described earlier, einmontiert in the needle body 1 to the functional unit in this embodiment of the finest needle sizes and pushed into the rearmost position.

In Fig. 21 is the guide bracket 8 for the guide finger 28 replaced by punctiform, projecting into the opening 7 nests 30 on the outer sides of the needle body 1. A narrow die, which presses with its the opening slightly protruding edges on the needle shaft, forms micro-chips to the lower shaft side, which are there by the counter-holding surface to point-shaped Führungsscharten 30. The illustration shows two pairs of pairs on the lower side and in between a pair of pairs on the upper side of the shaft.

Fig. 22 shows a section through the pair of nip formed on the left side of the needle. On the right side of the needle you can see the view of the pair of nipples further down the other side.

In Fig. 23 is shown in side view and front view in 10-fold magnification, as from the upper needle hook diameter to half material was removed to allow for this embodiment as low as possible mesh heights. Due to the lower slot depth, a recess can be provided for the same target on the back of the needle body 1.

Fig. 24 shows the second type of functional unit swing link needle in a needle channel, in which the connecting bracket 8 is fixed with its open legs 9 in guide recesses 7 of the needle body 1, wherein the closed ironing head 10 engages leading into a guide window 13 of the vibrating member 11. In addition, a magnetic strip 22 is provided in the knitting lock instead of the holding balcony 26 and the stop tooth 14, which acts on a needle channels protruding comb of the vibrating member 11, that allows by braking action of its relative movement to the needle body 1. Due to the additional lateral guidance of the vibrating member 11 in the needle body 1, this design is also used for outside of channels needles, z. B. in warp knitting machines, advantageous.

In the needle body 1 according to Fig. 25 with in the lateral guide recesses 7 z. B. by means of a laser welding point, the open legs 9 of the connecting bracket 8 is attached.

Fig. 26 shows how Fig. 25 an alternative attachment of the connecting bracket 8, in which a leg 9 is shorter than the other angled, so that after inserting the bends in the in a side view according to Fig.27 illustrated breakthrough 7 of the needle body 1, a fixation in the longitudinal direction occurs. The longer breakthrough 7 in Fig. 28 serves to perform the relative movement of the vibrating member 11 to the needle body 1, so that the first described type with fixed head 10 of the connecting bracket 8 in the swing member 11 is possible.

In Fig. 29 the swing member 11 is shown from the front and rear, between the side view with guide window 13 and, analogous to the needle body, in the rear boundary on both sides mounted guide grooves 16th

When swing member 11 in Fig. 30 the guide grooves 16 are produced without cutting. For this purpose, a gap 17 is provided in the rear boundary of the oscillating member 11, so that the recesses 16 can be impressed by means of two mutually acting punch, wherein the gap 17 is reduced by material displacement.

In the two end positions of the oscillating song 11 in the needle body 1 according to Fig. 31 the guide window 13 is slightly angled in the swing member 11, and the support surface extends parallel to it, such that when advancing the swing member 11 of the connecting bracket 8 slightly raises this front, causing the transfer tip 12 performs a small transverse movement. For this embodiment, it may be appropriate to provide a wear insert V in the head 10 of the connecting bracket 8.

To Fig. 32 (Side views of the functional unit swing member needle) is also a small in the two end positions of the swing member 11 Transverse movement of the transfer tip 12 is provided during the forward movement of the oscillating member 11. In this case, there is an increase in the sliding surface of the oscillating member in the rear position in a latching point 21 of the deposition 5. When advancing the vibrating member 11, the increase from the latching point 21, whereby the transmission tip 12 is slightly raised, the guide window 13 by an angling the tilting movement follows.
