Description

  An apparatus for machine knitting with at least one continuous yarn is known, and the yarn moves as a loop through the previously formed loop and forms a new loop. In one of these (Patent Document 1), the walls of the needle track each have a recess that opens at the top, and the recess forms a longitudinally moving edge. Furthermore, the transfer hook is held and embodied in the needle track so that it can be moved backwards through the central longitudinal edge of the recess by means of a transfer hook which can be moved vertically and vertically.

  In another device of this type (Patent Document 2), the continuous thread has a groove under the needle hook. The groove has a transfer hook that is pointed downward and can move horizontally and vertically. In this device, the needle hook is offset by the amount of penetration depth of the transfer hook.

  In the third device of this type (Patent Document 3), the continuous yarn under the needle hook has a groove, and a downwardly-pointed transfer hook that can move horizontally and vertically enters the groove. In an upward movement with respect to the needle hook, the front contact surface of the transfer hook moves away from the needle hook and perpendicular to it by the depth of the area of the transfer hook engaged with the groove.

  The current state of these types of machines is difficult and quite different, and the appearance of insignificant details can determine whether these versions are actually established. The known device shares the feature that the transfer hook is pointed downward in order to maintain the last loop formation where a new thread is pulled (pulled to form a new loop). This configuration has various advantages of loop formation that was previously customary.

  From Patent Document 4, a machine knitting method is known. Although an upwardly sharpened transfer hook is used, the fluff's inner movement that occurs only perpendicular to the needle causes the fluff to stick particles that prevent the loop from moving under the transfer hook. Due to the resistance of the machine needle track, the reliability of the movement of the loop to the transfer hook has hampered the establishment of currently known methods.

  Embodiments of the present invention are described in connection with FIGS. 1-4 show the principle of loop formation.

  FIG. 1 shows a needle 1 having a needle handle 3 and a needle hook 2. The needle hook already contains the thread F. The upward-pointing transfer hook 12 with the handle 11 is effectively connected to the needle hook 2. The handle 3 of the needle 1 has a recess 6 that coincides with the forked ridge 16 (FIG. 2) of the transfer hook 12. The handle recess 6 of the needle 1 ends with an upper part having a cheek taper surface 7 and a lower part having a partially chamfered recess 8. This sliding surface cooperating with the beveled point 18 (FIG. 2) bevel 18 of the transfer hook handle 11 makes it easier to engage on both sides. The cheek taper surface 7 of the needle handle 3 and the slope 17 of the transfer hook handle 11 are arranged so that they are effectively connected at a position where the handle 11 of the needle 1 and the transfer hook 12 is located.

  The recess 8 is located below the cheek taper surface 7 of the needle handle 3. When the relative movement of the needle 1 and the transfer hook 12 occurs, these two elements (1 and 12) are separated from each other by an amount x. z represents the vertical motion tolerance of the element (needle 1 and transfer hook 12). Within this range, the inner position of the transfer hook 12 on the needle cheek 4 is guaranteed.

  In FIG. 1, since the handle 11 of the transfer hook 12 slides along the cheek taper surface 7 together with the raised portion 16, the transfer hook 12 starts to move laterally and positive engagement connection with the needle handle 3 occurs. This also unlinks the two elements (1 and 12). In order to achieve the outer position of the transfer hook 12 while the needle is retracted, the recess 6 must be recessed by an amount y (approximately corresponding to the travel of the needle). The old loop is located on the transfer hook 12. This hook has a side offset 10 (seen in FIG. 2) in the region of the needle cheek 4 that is intermittently guided in the needle groove 5.

  FIG. 2 shows the position for pulling a new loop through the old loop of the needle hook 2. While the transfer hook 12 is in the upper outer position, the thread F is formed into a new loop. The recess 6 and the ridge 16 are no longer engaged with each other. The old loop is located just above the knockover edge A.

  Thus, in a two-element three-method step, a loop is formed instead of the previous four-method method step. The backward movement of the transfer hook 12 follows the backward movement of the needle 1 with the new thread introduced, releasing the loop it holds. The third stage has the step of upward movement of the needle 1 and the transfer hook 12. That is, during the forward movement of the needle 1, the connection with the transfer hook handle 11 occurs in the needle track, and the forward movement coupled to the upper position continues. Since the transfer hook 12 enters the needle cheek 4 and makes it possible to compensate for deviation tolerances present in the needle track, the connection in the needle track has an important reliability advantage.

  Only with the mutual longitudinal movement of the two handle parts without a control element in the needle cam, an advantageous small lateral movement of the transfer hook 12 takes place. These are simply structured parts having the same handle thickness with no deviation or overlap. With modern stamping techniques, the bent operation is unthinkable, so the required accuracy is guaranteed. The typical needle manufacturing operation now required is in the front portion of the transfer hook and the subsequent needle groove. The present invention allows a small cheek height, i.e., a small loop, and increases the freedom of design of the needle hook 2 with respect to the cheek height.

  In FIG. 3, the transfer hook 12 has moved backwards, so that the old loop has been thrown through the knockover edge A.

  FIG. 4 shows a new loop formed as a result of the forward movement of the needle 1. During the upward movement of the needle 1, the raised portion 16 on the transfer hook handle 11 returns to the recess 6 of the needle handle 3. This connecting operation causes an inner lateral movement of the transfer hook 12 to the needle groove 5. During further forward movement of the needle 1, the two elements together reach the upper position in FIG.

  In the coupling operation, at high speeds it is important that the incoming needle movement is coordinated with the transfer hook movement that begins just before it.

  1-4, there is a control support in both the rear region of the needle handle 3 and the rear region of the handle 11 of the transfer hook 12 (not shown). The most recently formed loop is maintained in the needle cheek 4 in the holding area of the transfer hook 12 at the needle cylinder or bed knockover edge A. Once a new thread F is introduced into the needle hook 2, the needle 1 starts to be pulled. Lateral movement of the transfer hook 12 takes place and the transfer hook is lifted from the needle cheek 4 so that the needle hook 2 passes the transfer hook 12 without friction. The needle handle 3 and the handle 11 of the transfer hook 12 are surfaces parallel to the base K of the track, and have contact surfaces that complement each other by positive engagement in the connected state (FIG. 3). In the front region, they are offset by the desired amount of lateral movement x of the transfer hook 12.

  FIGS. 5 and 6 magnified by more than 2 times show the important advantage of the oblique lateral movement of the transfer hook 12 into the needle groove 5 which is particularly pronounced in the precision version of the needle. The transfer hook is positioned by a holding part bb (FIG. 6) in the recess 9 behind the needle cheek 4. In the known versions (Patent Documents 2 and 3), a slightly oblique position of the transfer hook is required for slightly transferring the loop for transfer from the introduction part to the holding part. The version according to the invention avoids this inconvenience and creates a safe transition. Since the handle 11 is united with the holding area bb of the transfer hook 12 with the entire thickness, the center deviation of the tip for the introduction area aa can easily occur. The loop reaches the holding region bb without slip resistance. The oblique lateral movement of the transfer hook 12 with respect to the needle 1 is self-cleaning in the needle groove 5. Unlike the lateral movement that occurs perpendicular to the needle 1 of one known device (Patent Document 4), the lint does not stick and does not accumulate. As shown in FIG. 7, which is a cross section passing through the introduction region aa, it is also possible to widen the needle groove width beyond the thickness of the handle as described above.

  When the transfer hook 12 is lifted from the cheek region to the height of each hook in the reverse stroke of the needle 1, a problem-free transition from the introduction portion of the transfer hook 12 that has entered the cheek to the holding portion becomes possible. A slight expansion of the loop is not necessary. Furthermore, this has another advantage, and a cheek taper surface is easily made here. All that is needed is a short open groove in the needle that ends in a small dimple behind the cheek. When the introduction part of the transfer hook rotates to the needle cheek 4, the holding part of the transfer hook 12 is located in this groove. While the inner movement of the transfer hook 12 occurs in the side guides of the needle track, lateral cross compensation is ensured by the coupling operation as the needle 1 passes.

  FIG. 8 shows a portion passing through the holding portion bb.

  FIG. 9 clearly shows the design freedom of the hook height relative to the cheek height.

  10 to 12 show that the inner movement of the transfer hook 12 occurs via the lubricant 19a on the needle cam. Eventually, similar to FIGS. 1-4 for the needle hook 2 and the transfer hook 12, a parallel handle with corresponding recesses 6 and ridges 16 and corresponding cheek taper surfaces 7 and 17 are obtained. The connection is made by a protrusion 14 aligned with the transfer hook 12, similar to the tip 18 (FIG. 2). This engages a groove 15 at the end of the surface of the recess 9 and further serves to compensate for lateral tolerances of the transfer hook 12 when the transfer hook enters the groove 5 in the needle cheek 4.

  FIG. 13 relates to the “tack” knitting function. Here, once a new thread F is introduced into the needle hook 2 by means of a control support (not shown) of the transfer hook 12 and as a result of the connection, both loop forming elements (needle 1 and transfer hook 12) The loop overlying the knockover edge A moves so that the loop located on the transfer hook 12 slips from it, and eventually, in the subsequent loop forming operation shown in FIGS. 2 and then rest on the transfer hook 12. Using known techniques with different height control supports, selection of the needle through the cam to be “tacked” is made. A control cam in the needle cam is coupled to the control support portion.

  In order to achieve tuck loop patterning, the present invention has yet another advantage. In contrast to current prior art, the moving needle always draws the same course of motion. When creating a tuck loop, a small reverse pulse is applied to the control support of the transfer hook 12 after the introduction of a new thread and before the backward movement of the moving needle, and eventually both elements are transferred by non-positive engagement. Is guided backward by the length of. Eventually, the previous loop returns from the transfer hook 12 to the needle throat and reaches the newly introduced thread. The yarn is then transferred.

  The present invention makes it possible to freely program and operate individual needles. For this purpose, an actuating magnet with a very fast reaction time is used. At high speeds, the timing cycle within one needle pitch is minimal and therefore very short control movements are required in advance.

  Figures 14 and 15 show how the travel is limited to about 1 millimeter. In FIG. 14, after the protruding position (FIG. 1 or 10) where the new thread F has been introduced, all the needles of the machine cam are moved backward by an amount m via the control support (not shown) of the transfer hook 12 Moving. The old loop is located in the front area of the transfer hook, so that a new thread for loop formation is pulled behind the part f (FIG. 16). However, when the tack function is performed, a travel stroke n on the order of 1 millimeter is sufficient to perform this pattern operation (FIG. 15).

  FIG. 16 is a greatly enlarged basic view of the plan view of the cam track s. In the part f, when the control support part passes the track in the direction of the arrow, a tack function occurs. As the control support passes through the machine cam, an area is provided before the reverse stroke of the needle, where the necessary reverse pulse to one needle, for example electronically controlled according to the design pattern, creates a tack loop. If a tack loop is not created, the position shown in FIG. 10 is maintained during this pass. If there is only a mechanically activated needle selection, a connected retraction of both loop-forming elements from the position shown in FIG. 10 to the position shown in FIG. In the case of an electronically activated needle selection, this retraction is first performed for all needles from the position shown in FIG. 10 to the position shown in FIG. 14, and then pulsed to the position shown in FIG. Retraction is performed for the individual needles from the position shown in FIG.

  17-20 show method steps of loop movement for a flat knitting machine. The loop formation according to the invention can likewise be advantageously used for weft knitting as well. Two long straight needle beds-similar to circular knitting machine cylinders and dials-are facing each other and tilted at an angle of 100 °, each having one needle 1 and a transfer hook 12, so that the gap The needles cross each other from their respective beds. The needle 1 has to be retracted due to the bed displacement occurring in the longitudinal direction. The most recently formed loop depends from the transfer hook 12. The needle tracks of both beds are exactly opposite to each other during the moving process.

  In this technique, different multi-faceted patterning effects can be achieved as a result of the longitudinal displacement of the needle bed and the subsequent movement of the loop to the other bed surface. The transfer itself is a complex operation and requires a complex latch needle with spring elements and side recesses that are pierced by the needle taking over the loop. Thus, in subsequent needle retractions that deliver the loop, the loop is transferred to the other bed surface. In contrast, if the transfer hook 12 as described in this type of known device (Patent Document 4) has two parallel sheets, the needle 1 used for knitting is basically changed. The move is performed without

  In FIG. 17, the right transfer hook 12 has moved considerably forward with the plate, and the loop to be moved hangs from approximately the center of the free opening between the two needle beds.

  In FIG. 18, the left needle 1 taking over the loop has moved forward together with the hook 2, while the right transfer hook 12 is stationary, so that the left needle has a crescent shaped introduction ramp 20 (FIG. 24). Through the loop and lamina 11 to be transferred.

  In FIG. 19, the right transfer hook 12 is retracted and the loop to be transferred eventually is located on the left side of the bed.

  In FIG. 20, the needle beds are placed in their basic “needle facing gap” position for a cleanup operation. A new thread is introduced into the left needle hook 2 and is then pulled through the loop held by the left transfer hook 12 when the left needle 1 is retracted.

  21 to 23 show a special configuration of the needle hook 2. If there is a side offset of the needle bed over multiple needle pitches, there will eventually be considerable tension in the lateral direction of the loop, so that the needle passing the loop will hit the thread portion at the head instead of the loop opening.

  The shoehorn-like protrusion 21 of the needle hook 2 ensures that the opening of the loop is found at this point just below the transfer hook 12 and creates a path for the transfer operation of the needle head 2.

  In FIG. 21, the diameter 22 of the uncurved front portion of the needle hook 2 is further reduced, so that after a subsequent compression operation in the lateral direction of the needle 1, it becomes a flat shape with half the thickness of the hook.

  FIG. 22 shows the compressed reduced portion 22. This is compressed laterally of the needle 1 up to the inner course of the hook 2 to be bent later and the width of the needle hook 2 in a straight line, and the front part bent 180 ° backward after the hook is bent is The version of hook shown in FIG. 23 is made equal to the thickness.

  FIG. 24 shows a plan view of the back surface of the thin plate in the region (FIGS. 5 and 9) of the adjacent spreading portion up to the track width of the needle groove and recess 9.

  Figures 25-29 are examples of loop forming elements of the present invention for warp knitting machines. These elements are fixed alongside the rear region of the handle—so-called bars—and project through the front edge of the bar with a pitch spacing corresponding to the desired fineness. The problem here is that the freely protruding handle portions of both bars must be exactly aligned with each other over their considerable length. Various factors, especially the thermal expansion of the machine, play an important role here. It is therefore necessary to guide the cooperating elements inside each other at important points, for example proposed by a latch-like projection engaging the needle groove.

  In a very fine version of the needle, the two versions of the handle have the same thickness, so a small guide bracket 24 surrounding the handle is one preferred embodiment from a friction standpoint. This guide bracket is fixed to the handle 11 of the transfer hook 12, for example, similarly to the latch fastening in the knitting machine needle. Here, like a known type of latch bearing, two molds that act in opposition to each other in a straight line with the fastening hole press the stub from the side part into the fastening hole 25. FIG. 26 clearly shows the type of fastening of the aa portion of FIG.

  FIG. 25 is a basic view of the location of both loop forming elements in separate needle bars. The bars are held so as to be able to rotate about a rotation axis which is located at a relatively large distance laterally from the needle elements and these elements move along a longitudinal circular trajectory as shown in FIGS. . While the needle 1 is fastened to the track of the needle bar (not shown), the complementary compound needle parts formed on the holding connecting portion 23 with the same pitch are in contact with each other to contact the second bar (also shown in the figure). (Not shown).

  In FIG. 25, the handle protruding from the holding connecting portion 23 is embodied as a spring 26 in the extension portion. The spring is slightly prestressed, and in this relative position of the two bars of each other, the transfer hook 12 is located on the needle cheek 4 (FIG. 25), whereas in the other positions it is raised. As a result of the portion 16 sliding along the cheek taper surface 7 on the upper edge of the handle 3 of the needle 1, the transfer hook 12 maintains the outer position.

  Figures 27-29 show how loop formation is possible with only one bar assembly. The needle 1 fastened to the bar track at the rear of the handle 3 has an offset 28 and a gap is created in this area of the fastening cap 29. There, it is introduced so that the rear part of the handle 11 of the transfer hook 12 can move in the longitudinal direction without stress. In order not to create frictional heat during high-speed vibration, it is sufficient that the transfer hook part integrated with the connecting part (not shown) has a long part of the handle 11 only at the outer boundary. The side guides of the two elements 1, 12 in the loop-forming region are taken over by known tongue and groove connections or the U-shaped guide shown. As shown in FIG. 11, the outer movement of the transfer hook 12 occurs via the cheek taper surface 7 on the needle handle 3. For the relative movement of the transfer hook 12 with respect to the needle hook 2, a control rail 27 is provided over the entire length of the bar, which engages a corresponding groove in the handle 11 of the transfer hook 12. As shown in FIGS. 10 and 11, the two loop forming elements are connected by a protrusion 14 of the transfer hook 12 that engages a groove 15 at the end of the surface of the recess 9.

  30 and 31 are basic views of the position of the control rail 27. FIG. A heavy pendulum or a vibrating structure for fixing the bar 10 is not necessary. A lightweight vibratory device with only a small mass movement is sufficient. The control rail 27 is divided into portions that can be easily removed to replace the transfer hook portion.

  A guide holder 30 positioned parallel to the needle over the entire length of the needle bar has guide elements with appropriate partial spacing, such as a ball bushing 31. As the rail holder 32, a U-shaped vibration element having a fastening base 34 on the upper portion for the control rail 27 and designed at the lower portion for the vibration drive mechanism is moved up and down by a bolt 33 fixed to them. Can be moved to. The vibrating element 32 is coupled to the side to a shaft 35 used for the vibration drive mechanism. The side bearing plate 38 for the vibration drive mechanism is also fixed to the guide holder 30 at a partial interval. The vibration device is also used to move the needle 1.

  According to the invention, the generation of vibrations is done in three different ways.

  (1) Performed through the shaft 39 (axis A) held by the side surface portion 38. The radial cam 40 vertically moves the transmission element located on the connecting shaft 35 of the vibration element 32. Here, the compression spring 36 ensures the contact between the radial cam 40 and the transmission element 42.

  (2) It is carried out via an axially actuating cam 41 which is fixed to a shaft 39 which vibrates in the longitudinal direction and which operates on a transmission element 42 held under the rail holder 32.

  (3) It is carried out via a shaft (axis B) which is located on the side parallel to the guide holder 30 and performs the minimum rotational vibration. The connecting shaft 35 is moved so that the transmission lever 44 vibrates vertically.
