Abstract

PURPOSE: To make a system (segment width) smaller by arranging and constituting an insert/draw out plate relative to a pattern device in a specific shape equally to a capturing position where the intermediate position of a needle is lifted high. CONSTITUTION: When the needle 3 advancing into the system from the right side is selected, the needle is shifted to the high capturing position 37 along an orbit segment 36 and is returned to the ordinary capturing position 39 along the segment 38. The cam part of the insert/draw out plate 5 is so constituted as to be placed in at least the slightly lifted position as far as the needle 3 occupies the position higher than the ordinary capturing position 39 in order to slide the stitch hooked within a hook 3 onto a needle shank beyond an opened latch 3b at the time of a needle extruding stage of the stitch to the capturing position 37. The cam part is controlled so as to be arranged relative to the pattern device.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a knitting machine for producing knitted fabrics, which comprises a carrier having a plurality of guide webs, and a carrier disposed in parallel and between each guide web. a needle and a spigot/pull-out plate are provided, in which case at least partially opposing pushing and pulling movements in the needle and spigot/pull-out plate and additional spigots in the spigot/pull-out plate are provided to carry out the knitting operation. and a number of system sections with needle and insert/pull plate cam parts controlling the push-out and pull-down movements, and which are assigned to these system sections and adapted to the pattern. a patterning device used for performing a knitting operation, the selected needle being first raised by the patterning device to an intermediate position prior to performing the knitting operation; .

(Prior Art) The knitting machine of the above-mentioned type, which is disclosed in German Patent Application No. 3600666 and German Patent Application No. 3602903, is a mechanical pattern having a large number of pattern sliders. Equipped with equipment. Each pattern slider, arranged one above the other in a number of flats, acts on the pattern base of a pivot plate arranged so as to be able to pivot radially below the second dollar. In this known knitting machine, in order to realize a ternary method called the so-called "three-way technique," that is, a ternary method that appropriately selects the knitting process, capture process, and non-knitting process in one knitting system. , three mutually different pattern slides are required, via which the pivot plate is transferred into one of the three possible pivot positions in each case.

Many known electrical or electromagnetic pattern devices are generally controlled by a ``0'' signal and a ``1'' signal, and therefore only dual methods apply to these devices; Even with the use of any one device (for example the device according to DE 37 12 673) it is not possible to carry out the pattern manipulation as described above immediately.

For this reason, conventionally, they are paralleled to each other and each one
The ternary method had to be realized by using electrical or electromagnetic pattern devices assigned to each system section, and only half of the total number of systems could be used in practice.

One possible measure to address this shortcoming is to reduce the width of the system partitions.

If the width of the system partition is to be arbitrarily reduced, a flexible pattern shape is a prerequisite.

This means that pattern formation on a knitting machine of the type mentioned at the outset must be carried out in a satisfactory and flexible manner. In this case, when trying to form various patterns by exchanging some of the cam parts in a set, the system width in all system divisions is determined by the widest cam part in the set of cam parts It is determined by the width of Since the respective minimum width of the cam section is predetermined for reasons of knitting technology, it is not possible to arbitrarily reduce this value. Therefore, it often happens that the width of the system partition has to be larger than the value that would be required in many patterns.

Furthermore, when operating a knitting machine of the type mentioned at the beginning at extremely high speeds, it is necessary to keep each knitting needle at all times in order to avoid breakage of the needles due to excessive impact of the needle butts on the different cam parts. A form-fitting guidance is also required. In this respect only, a measure has already been proposed in DE 26 36 008 to guide the knitting needles as collision-free as possible by providing an additional movable butt. However, this type of device cannot avoid the following disadvantages which also occur in other known pattern devices. That is, the disadvantage is that the needle butt itself or a slider, pusher, or similar member used to control the needle butt is provided at three selection positions of the pattern device, so that the needle butt itself, or the slider, pusher, or similar member used to control it, is provided at three selection positions of the pattern device, so that the needle butt itself can be set at three selection positions, and a selected needle can be replaced with an unselected needle. This is due to collision with the divider tip of the separation cam section used for separation from the separation cam section. The frequency with which this type of problem occurs will be the higher the operating speed of the knitting machine, the greater the number of system sections, or the smaller the width and mutual spacing of the system sections are set. It has to be that expensive.

(Problem to be Solved by the Invention) Therefore, the problem to be solved by the present invention is to improve the knitting machine of the type mentioned at the beginning, and to develop an industrial technology to satisfactorily reduce the system width or system division width. The prerequisite for reducing the system width lies in ensuring that the various knitting tools are guided without colliding with each other and causing damage, while at the same time ensuring that the knitting machines used are capable of dual and/or Or, it must be achieved regardless of whether or not the machine is applicable to the ternary method, and regardless of whether or not the one-way method (flat knitting method with all needles) can also be carried out. Must be.

According to the measures of the invention proposed to solve the above-mentioned problem, the intermediate position of the needle is made equal to the raised capture position, and the insertion/extraction plate is It is arranged and configured relative to the patterning device in such a way that when the needle is pushed out to the high capture position, it still occupies the pushed out position, at least partially.

(Effects of the Invention) According to the present invention, since the needle is pushed out to a higher position than the normal capture position, the required divider tip of the separation cam part can be installed higher than in the normal case. Therefore, when a needle bat or other knitting tool enters the system section, the possibility that these parts will collide with the divider tip of the separation cam section is minimized, and the system It becomes possible to significantly reduce the width of the division.

Further advantageous features according to the invention are indicated in the respective dependent claims.

(Examples) Next, the present invention will be described in detail with reference to each embodiment shown in the accompanying drawings.

FIG. 1 shows the basic structure of a knitting machine related to the present invention using a nine knitting machine as an example. This nine-knitting machine has a carrier 1 in the form of a needle and plate cylinder. In the lower region of the carrier 1, a plurality of guides 2 with parallel axes are provided, each of which A needle 3 (for example, a latch needle in this embodiment) as a knitting tool is mounted between the guides so that it can slide parallel to the sleeve line of the carrier 1. Furthermore, in the upper region of this carrier 1,
A plurality of guide webs 4 with parallel axes are provided, between each of which an insert/pull-out plate 5 is mounted such that it can slide parallel to the direction of movement of the needle. This insertion/extraction plate 5 is constructed in such a way that it can also carry out an additional insertion movement in the longitudinal direction of the needle 3 or transversely to its direction of movement.

The guide web 4 for the insert/pull-out plate 5 is
They are inserted into the carrier 1 with the same pitch as the guides 2 for the needles 3, but are arranged with a gap in relation to the guides 2, so that in each case one needle 3 is connected to two insert/pull-out plates. 5, or the opposite positional relationship will be established.

The needle butts 6 to 7 of each needle 3 cooperating with an operating cam are provided in the lower part of the insert/pull-out plate 5, the operating cam being formed in a cam part jacket 8 surrounding the carrier 1. .

As in the needle 3, the insert/pull plate 5 also has butts 9, 10, 11 which cooperate with the operating cams of the cam jacket 8. In this case, the plate butt 9 is used to raise and lower the insert/pull plate 5 parallel to the direction of movement of the needle 3, whereas the plate butts 10 and 11 move the insert/pull plate 5 transversely to the needle movement. It is used for pivoting about the protrusion 12 in the direction.

The construction of a knitting machine of this type as well as its function is known from German Patent No. 3,311,361 and therefore will not be described in more detail here. The reason why this type of nine-knitting machine is particularly suitable for achieving the object of the invention is that the butts 6 to 7 of the needle 3 correspond to the butts 9 to 1 of the insert/pull-out plate 5.
1, the space required to mount the needle pattern device is sufficiently secured.

When using the knitting machine shown in FIG. It's just a thing. In contrast, in the embodiments shown in FIGS. 2 and 3, one patterning device is arranged in each of several or more preferably all system sections.

These system divisions include a needle pusher, one for each needle 3, as a separate knitting tool.
14, these needle pushers 14 are arranged below the needles 3 in the same guide channel formed in the carrier 1.

The needle 3 in this embodiment is provided with only a butt 6, and the butt 7 is omitted. Each pattern device has a cam part 15 with a push-out cam 16 and a cam part 17 with a pull-down cam 16, respectively. Each needle pusher 14 has one butt that cooperates with the push-out cam 16 and a butt 20 that cooperates with the pull-down cam 16.
and a return adjustment spring 21 supported at the base of the pusher guide passage.

All needle pushers 14 carry out a movement together with the needle 3 and the insert/pull plate 5 in the direction of the arrow V shown in FIG. In this case, the needle busher 14
3(b) by a radially acting cam (for example cam 15a and/or 15b shown in FIG. The needle pusher 1 is rotated radially inward as shown in FIG.
4 is guided along a selection device 22 which secures or releases it in a pattern (details in this regard can be found, for example, in German Patent No. 3 7 1 2
6 7 3 (see cam 37 and/or 38). The released needle pusher 14 is pivoted outward again by the return adjustment spring 21 (
In FIG. 3 (river), one of the pusher butts reaches onto the pusher cam 16.

Immediately after this extrusion operation, the needle busher 14 is pulled down by a pull-down cam 16 acting on the busher butt 20 and is sent in the direction of arrow V to the patterning device in the next system section. The needle pusher 14 which has not been released for this purpose is indicated schematically by one busher butt 20 in FIG.
It passes through the cam part 15 without any pushing operation.

As the selection device 22, any known selection device commonly used in knitting machines can be applied.
More advantageously, electromagnets are used in combination with patterning devices which are also known (German Patent No. 37).
12673 specification). In order to avoid redundancy, this point will be clearly stated here.

Needle pusher 1 captured by extrusion cam 16
The upper edge of the butt 20 at 4 comes into contact with the needles 3 arranged above it when it rides onto the cam part 15, and these needles touch until the needle butt 6 is lifted onto the separating cam part 23. Push 3 upwards. In this case, the forced guidance of the needle 3 carried out by the needle pusher 14 is maintained until the needle 3 reaches the upper catching position. In FIG. 2, the butt 6a occupies exactly this catching position, and the needle pusher 14
immediately thereafter slides off the pusher cam 16 to be captured by the puller cam 16.

The separating cam part 23 has a divider tip 24 which is used to divide the selected needle 3 from the non-selected needle 3 in a manner known per se. The butt 6 of the needle 3 enters the free space 25 located in front of the separating cam part 23 from the right side as seen in the drawing plane of FIG. 2, in which the selection process must take place. In this case, the bat 6 cannot be guided by the cam part. selected needle 3
is lifted into the capture position, while the unselected needles 3 are left in the passing position. Furthermore, in this case the needle 3 in the preceding system section has just reached its deepest depressed position (sinking position) and is then raised slightly again. Therefore, when knitting is carried out at high speed or when a large number of needle cylinders are used,
The uncontrolled free space 2 of the needle 3 which is not forcibly lifted by the needle pusher 14
There is a risk that the needle butt 6 that has entered the inside of the needle butt 5 will collide with the divider chip 24.

Generally, the divider chip 24 is arranged so as to maintain a relatively small distance from the passage passage 26 formed between the cam part 17 and the separation cam part 23, so that the value of the knitting speed is large. As this progresses, it is inevitable that the risk of the needle 3 being damaged (crashing) increases significantly. However, in the present invention, since the selected needle 3 is forcibly guided by the needle pusher 14 to a higher position than the normal capture position, the distance from the divider tip 24 to the passageway 26 is set to a relatively large value, This makes it possible to significantly reduce the risk of needle breakage.

As shown in FIG. 2, the unselected bucks 3 are guided securely by the divider chip 24 into the passageway 26 and then sent to the next pattern device in the subsequent system section. On the other hand, the needle 3 that has been selected and pushed out into the high capture position is moved through the cam passage 28 formed between the upper edge of the separating cam part 23 and the lower edge of the further cam part 27.
through this cam passage 28, as implied by the butt 6b, and then lowered into the normal capture position. Furthermore, this needle 3 is guided in the usual manner after leaving the catching position to receive a thread (not shown) and is lowered back into the passing position.

The insert/pull-out plate 5 with butts 9 projecting into the cam passages 30 defined by the cam parts 29a and 29b as shown in FIG. controlled relative to needle 3. In this case, the trajectory of the pivoting movement carried out by the insert/pull-out plate 5 transversely to the direction of movement of the needle 3 is drawn with a thick solid line and is designated by the reference numeral 31;
The trajectory of the push-out and pull-down movement carried out by the drawer edge 5a of the drawer plate 5 in a direction parallel to the direction of movement of the needle 3 is depicted in broken lines and designated by 32. Furthermore, a trajectory 33 drawn with a solid line of normal thickness is a trajectory for guiding the needle head of the extruded needle 3, and a trajectory 34 drawn with a dashed-dotted line is a trajectory that guides the needle head of the extruded needle 3.
A needle head movement of the needle 3 guided in 6 takes place, the direction of movement being parallel to the direction of the arrow W.

If this is not selected, the needle 3 entering the system from the right side in the drawing plane of FIG.
and is lowered for a short period of time at track segment 34 even lower than the passing position;
It is reliably avoided that the yarn fed to the system section is completely or partially received by this needle 3. On the other hand, if needle 3 is sent,
The needle 3 is first moved along the track section 36 to a high capture position 37 and then returned along the track section 38 to the normal capture position 39. In these three capture positions, the distance between the needle head and the drawer edge 5a of the insert/pull-out plate 5 remains at the value indicated by the double arrow 40. In this case, the numerical value indicated by the double arrow 40 is
Although the latch of the latch needle, ie the movable latch 3b, has already been opened, the previous stitch is still set to remain on the latch 3b. Generally, the tip of the latch on the needle 3 is located just below the drawer edge 5a in the normal capture position.

The stitch formed in the previous system section and still hanging in the hook 3a of the second needle 3 is intentionally pushed over the open latch 3b during the needle extrusion step to the high capture position 37. In order to be able to slide it onto the shank, the cam part 29a129b of the insert/pull plate 5 is such that the needle 3 is in its normal capture position 3.
As long as it occupies a position higher than 9, it is configured to be placed in an at least partially raised position and is arranged relative to the patterning device, so that the control of the insert/pull plate 5 takes place. The insert/drawer plate 5 is
It occupies its highest position when entering the system section from the right along the track section 41 shown in FIG. Furthermore, as this insert/pull-out plate 5 is lowered from its highest position along track section 42 to track section 43 as its lowest position, track 3
2 and the trajectory 33 until the double arrow 40 appears approximately at the end of the trajectory segment representing a high acquisition position 37.
is set to reach a distance indicated by and taper off therefrom almost constantly along track segments 38, 42.

Therefore, in the area of the track section 36 the distance between the tracks 32 and 33 is always kept smaller than the distance indicated by the double arrow 40, so that the needle 3 can be temporarily returned to the normal acquisition position 37. In this case, the stitch formed in the preceding system section does not slip down below the latch 3b, and the divider tip 24 can occupy a correspondingly higher position (FIG. 2). ).

Another advantage obtained by the above-mentioned device of the invention is that this device also functions effectively when the extrusion height of the insert/pull-out plate 5 is changed to make the stitch length variable. . When the stitch length is extended, the insertion/extraction plate 5 enters the system section along the track located above the track section 41 in FIG. 4, so that the tracks 32 and 33 are The distance between is reduced within a critical range. Therefore, the stitch length is not shortened to an arbitrary value, but a predetermined limit value is defined, but the stitch length can also be shortened by basic adjustment of the knitting machine in the type related to the present invention. Since it cannot be changed arbitrarily, this limitation does not pose a problem in practice.

Particularly in the so-called "sinking peak" range, ie at the lowest position of the needle pull-down cam, in order to guide the pushed-out or non-pushed-out needle 3 during the pull-down without collision, it is advantageous to use the arrangement shown in FIGS. As shown in FIG. 6, the needle 3 is provided with a known slider 47 forming a movable control butt 46. Regarding other parts in the figure showing this example, please refer to Section 2.
The same reference numerals as in FIG. 3 and FIG. 3 are used.

The slider 47 has the same thickness as the needle shank and is inserted into an outwardly open notch 48 in the shank. This slider 47 is held on its sides, for example, by guide webs 2 for the needle 3 shown in FIG.

A defined clearance is formed between the upper and lower edges of the recess 48 and the associated upper and lower edges of the slider 47, so that the slider 47 can be moved in the direction of movement of the needle. Parallel but limited reciprocating movements can be performed.

The cam device according to the embodiment shown in FIG. 5 is constructed in the same manner as the embodiment shown in FIG. It is divided into parts, each of which is designated by reference numerals 17a and 17b, respectively. The lower edge of the cam part 17a forms a pull-down cam 16 on the butt 20 of the needle busher 14, while the upper edge of the cam part 17b limits the path of the needle 3 on the butt 6. This fruit! In the case of this example, the separation cam part 23 in FIG. can be done. On the other hand, the cam portion 17a and the cam portion 17
In the free space 50 formed between the separation cam part 23 and the separation cam part 51, a separation cam part 51 having substantially the same structure as the separation cam part 23 is arranged. , divider chip 24 according to FIG.
It is equivalent to the function of This divider chip 52 also occupies a high catching position, and as long as the divider chip 52 occupies this position, a collision of the control batt 46 on the slider 47 is reliably avoided even if the knitting machine is operated at high speed. .

This slide 47, together with its butt 46 and the associated cam parts 17a, 17b, 51, on the one hand, makes it possible to guide the needle 3 in a perfect form-fitting manner even in the area of the free space 49. However, it is not possible to guide all the needles 3 in a form-fitting manner, since the selection process has to take place only in a short region of the free space 50 located in front of the divider tip 52. On the other hand, the slider 47 guided in the passage passage 53 formed by the cam parts 17a and 51 moves the butt 6 of the needle 3 that has not been selected.
The slider 4 is guided in the working path 55 formed by the cam parts 17b, 51 and/or avoids a violent impact on the cam part 27 in the area of the submerged tip 54.
7 avoids a violent impact of the butt 6 of the needle 3 coming from the capture or knitting position on the cam part 17b by preventing an early descent of the needle butt 6 in the four free spaces. Even if this is ignored, the configuration of the present invention prevents the needle 3 from falling in front of the thread receiving portion and causing damage.

Since the shape and mode of action of the slider 47 are basically already known from German Patent No. 2,636,008, we will simply point out that there are known examples here to avoid repetition.

The difference between the embodiment according to FIGS. 2 and 3 and the embodiment according to FIGS. on the other hand, the divider tip 52 for the control butt 46 must be positioned sufficiently high.Furthermore, the stationary needle butt 6 controls all needle movements. In contrast, FIGS. 5 and 6(a),
In the embodiment according to (b), a movable control butt 46 holds the needle 3 in the passing position and the needle 3 is pushed by the needle busher 14 into a higher capture position,
A mode of construction is then adopted which also controls a controlled lowering process in the needle 3 after it has been lowered by the cam part 27 into the normal capture position.

If the patterning device according to FIGS. 2 to 6 is used, the selection (switching) between the unknitted state (passing position) and the knitted state (complete extrusion rather than capture) can also be carried out in a suitable manner. However, in order to carry this out, the needle 3 is moved into the separating cam section 51, since a satisfactory extrusion cam 16 cannot be obtained due to the desired small system width.
It is thought that it will be necessary to push it out to a certain knitting position using the butt 46 and the slider 47. Furthermore, with two consecutive system divisions, it should be possible to implement the ternary method, and smooth left-right and flat knitting using all needles 3 would also be possible. On the other hand, if a control strategy is desired in which all needles 3 in one system section are selectively brought into the editing or catching position, the differences between the respective extrusion cams involved are small. Unless, on the basis of this, the two ejector cams are shifted laterally and thus considerably widen the width of the system section, or the number of systems is reduced to an appropriate value.
It seems that the intended purpose will not be achieved. Therefore, when forming the other patterns already mentioned, it will be necessary to reduce the number of systems or adopt a working method in which the selection of formation and capture is abandoned.

Therefore, the present invention provides another knitting tool, as shown in FIGS. 7 and 8(a) and (b), which is configured as an intermediate busher 58 that is slidable parallel to the direction of movement of the needle 3. used. This intermediate pusher 58 is seated between the needle 3 and the needle pusher 14 in the same guide channel in which they are seated, and has a butt 59. The groove pattern of the needle 3, the insert/pull plate 5, the needle pusher 14 and the slider 47 can be the same as in the other embodiments. Identical parts are therefore provided with the same reference numerals in this embodiment as well, and the same applies to the cam portions 29g, 29b of the insertion/extraction plate 5.

The system section shown in FIG. 7 is provided with four cam parts 61, 62, 63, and 64 located above and below each other. Pull-down cam 6 for 14 bats 20
5, whose straight upper edge is configured as a lower limit of the passageway 66 in the butt 59 of the intermediate pusher 58. The lower edge of the cam portion 62 limits the select passage 67 for the butt 59 of the intermediate pusher 58, and the straight upper edge thereof limits the select passage 67 for the butt 4 of the slider 47.
Free space 6 formed between cam parts 62 and 63 in 6
8 is formed as a lower limit part. The lower edge of the cam part 63 has on its entry side an edge which extends linearly at the knitting level and which then transitions into a pull-down cam 69 for the butts 4, 6 leading to the passing position. The upper edge of the cam part 63 is used for the bat 6 of the second dollar 3 and has a push-out cam leading to the normal capture position 70 and a section behind it that drops into the passing position. Further, between the upper edge of the cam part 63 and the lower edge of the cam part 64, the selected needle 3
A free space 71 is provided which allows the bat 6 to be raised over the high catch position 72 into the knitting position.

Subsequently, the lower edge of the cam part 64, together with the upper edge of the cam part 63, delimits the lowering cam for a normal needle that moves along the submerged tip 73.

A separation cam portion 74 having a divider tip 75 is arranged between the cam portion 61 and the cam portion 62, and the separation cam portion 74 passes through the passage 66 through the butt 59 of the intermediate busher 58 that is not selected. While lifting the five butts of the selected intermediate pusher 58 into the select passage 67
The butt 59 is then used to raise the butt 59 in the selection channel beyond the high catch position 76 to a full extrusion height corresponding to the knitting or insertion height of the needle 3. In the case of the embodiment shown in FIG.
Since neither the stationary butt 6 nor the movable butt 46 in the needle 3 is guided in its free space 68 to 71 and the selection is effected only by the intermediate pusher 58, in this embodiment the intermediate pusher 58 is The arrangement is such that during the selection process the butt 59 is pushed into a high catching position 76 and the needle 3 is brought into a high catching position 72 in a controlled manner.

Accordingly, the divider chip 75 can also be arranged at a correspondingly high height, so that the five butts of the intermediate pusher 58 to be controlled within the passageway 66 are prevented from colliding with the divider chip 75.

In the embodiment shown in FIGS. 7 and 8, the selected needle pusher 14 lifts the intermediate pusher 58 via the divider tip 75 onto the separation cam portion 74, after which the pusher is pulled down by the pull-down cam 65. will be carried out. Subsequently, this separation cam portion 74 lifts the selected intermediate pusher 58 together with the needle 3 into the knitting position.

Further thereafter, the separation cam 74 lowers the needle 3 to the sunken tip 73, but in this case the selection passage 67
is configured to prevent the needle 3 from falling. Furthermore, it would also be possible in this case, as an alternative, to provide a suitable working channel for the butt 46 in the slider 47.

If the needle pusher 14 is not selected, the five butts of the intermediate pusher 58 reach into the passageway 66. On the other hand, the butt 6 of the needle 3 is
into the normal capture position 70 and is then captured by the lowering cam also of the cam portion 64. As is clear from FIG. 7, the butts 6 to 46 of the needles 3 to slider 47, which have been pushed into the knitting position or the normal capture position in this case, are at least partially spaced apart from each other by a very small t-th interval. Perform a movement on each orbit that only has. Therefore, on the one hand extremely small system widths become possible, but on the other hand the free space 68
, 71 becomes impossible. However, if the intermediate pusher 58 is used, the selection of the knitting position and the picking position can nevertheless be accomplished without errors or crashes.

The only point that must be taken into account in such a patterning method is the constraint that the needle 3 or slider 47 pushed out into the normal capture position 70 cannot be guided form-fittingly inside the free space 68 or 71. It is where it occurs. Therefore, when high-speed knitting operations are carried out, the occurrence of pattern errors such as those caused by the needle 3 brought into the normal capture position 70 being unintentionally thrown into the knitting position is completely avoided. It cannot be excluded. However, in order to deal with such a situation, it is natural to limit the knitting speed to a predetermined value using the cam section shown in FIGS. 7 and 8 and/or to limit the knitting speed to a predetermined value. It is conceivable to provide the upper edge of the part leading to the normal capture position 70 with a rounded chamfer, for example a parabolic shape. Although this measure results in only a small overall reduction in knitting speed, this has the advantage of reducing system width and allowing higher knitting speeds in other knitting styles. You will have to accept it regardless of the situation.

FIG. 9 shows an inset/
a track 77 for rotating the drawer plate 5;
A track 78 for the axial movement of the insert/pull plate 5, a track 79 for the needle 3 to be pushed into the knitting position, and a track 80 for the needle 3 to be pushed into the capture position are shown. In this embodiment, too, the distance between track 78 and track 7 is always the same as the normal capture position 83 until reaching its high capture position 81.
The distance 82 is set to be smaller than the distance 82 corresponding to the mutual spacing between the orbits 78 and 80 in . Such measures ensure that only when the needle 3 is pushed out from the high catch position 81 to the knitting height 84 can the previous stitch be slid over the latch tip and onto the needle shank. . Regarding other points,
These orbits 77, 78 and the orbit 31 shown in FIG.
There is no difference between this and 32.

In order to produce a circular knitting machine equipped with a large number of knitting systems, all of which are constructed in the same way and capable of producing various different patterns simply by replacing the cam section, the following steps are required: In addition to the cam device and needle pusher device shown in FIGS. 7 to 9, it is possible to use additional cam parts in combinations as shown in FIGS. 10 to 13, and this embodiment Also, the same parts are given the same reference numerals.

FIG. 10 shows an embodiment in which the cam arrangement according to FIG. 5 is additionally provided with an intermediate pusher 58 according to FIG. Instead of the cam part 17a, a cam part 87 is provided which has a straight upper edge and which pulls down the bat 20, which together with the lower edge of an additional cam part 88 are provided in the free space 8.
9, the butt 59 of the intermediate pusher 58 is selected within the free space 89. Furthermore, within these eight free spaces there is provided a separation cam part 90 with a divider tip 91 located directly below the high capture position. The upper edge of the separation cam part 90 forms, together with the lower edge of the cam part 88, a select passage 92 leading from the high capture position to the normal capture position and from there to the passing position. The lower edge of the bat 5 along with the upper edge of the cam portion 87
9 is limited. Furthermore, the cam part 8
The upper edge of 8 forms a passage passage 53 for the butt 46 in the slider 47 together with the separation cam part 51;
As in the embodiments shown in FIGS. 5 and 6, a choice between passing and capturing is made possible.

In the embodiment shown in FIG. 11, above the cam part 87, other cam parts 95, 96, and 97 are arranged one above the other, and in this case, between the cam part 87 and the cam part 95, In the free space formed by the batts, there is provided a separating cam part 98 with nine divider tips, which is also located directly below the high catch position of the five bats. In other respects, after the butt 59 has reached the high capture position and the separation cam portion 98
This embodiment and the embodiment according to FIG. There is no difference between the examples. In this case, the axial play of the slider 47 in the recess 48 of the needle 3 is such that the same free space 50 and separating cam part 51 can be used for the butt 46 in the embodiment according to FIGS. 10 and 11. Designed.

Therefore, in the embodiment shown in FIG. 11, it is possible to select between organization and non-organization.

If it is intended to construct one knitting system using all the needles 3, it is effective to provide a cam device of the type shown in FIG. 12.

By the way, in this cam device, two cam parts 1'0
1, 102 form a permanently closed cam passage 103 for the butt 6 of the needle 3, with a corresponding free space 104 provided for the butt 46,
Selection device 22 is not used. Note that when the control signal is not sent to the control magnet, by configuring the selection device 22 so that all the needle pushers 14 are pushed out, the cam part 87 and the cam part 105 located above it are In between, the butt 5 at the intermediate busher 58
It would also be possible to create an appropriate free space 106 for this purpose. In all existing organizational systems,
If a knitting operation is to be carried out using all the needles 3, it is desirable to completely remove each needle button shear 14 to avoid unnecessary wear.

In this case, 5 bats in all system divisions are 1
Pass through two passing trucks.

If it is to be possible to carry out the ternary method rather than the binary method described so far, the cam arrangement shown in FIG. 13 is used. In this embodiment, two mutually adjacent system partitions 107, 108 are combined into a single system partition. In the preceding first system section 107, needles 3 that are only pushed into the normal capture position 109 are selected by the selection device 22a.

The associated cam section therefore has a butt 5 in the intermediate pusher 58, which in this case is used only for transmitting the pushing movement of the needle pusher 14 to the respective needle 3.
A free space 110 for 9 is provided. The original selection operation is performed by the bat 46 of the slider 47 and a separation cam section 112 disposed in the free space 111, and this separation cam section 112 separates the sent bat 46 from the unselected bats 46. Divider chip for 1
14, making it possible to push the corresponding bat 46 to a high catching position.

The unselected butts 46 are subsequently pushed out a little further by the separating cam portion 112 and transferred into the working passage 115 or into the holding passage. Each butt 6 in the associated needle 3 is first pushed into a high catching position in the free space 116 formed between the two cam parts 116, 117 and then immediately thereafter by the lower edge of the cam part 117. It is guided in such a way that it can be lowered into the normal capture position 109.

In this case, the slider 4 in the notch 48 of the needle 3
The axial play of 7 is such that the lower edge of the slider 47 rests on the needle 3 when the high capture position is reached, while the upper edge of the slider 47 rests on the needle 3 when the normal capture position 109 is reached. It is designed to abut on 3. The needle 3 in its normal capture position 109 is therefore in the working channel 11
It is supported on a slider 47 that is guided within the holder 5 to ensure that it does not slide down.

The succeeding second system section 108 is constructed essentially identically to the system section shown in FIG. 11, the only difference being that a cam section 119 is additionally provided. This additionally provided cam part 119 is provided in order to extend the working path 115 and to prevent the needle 3 from falling into the selection area or unintentionally reaching into the passing track. 95 and cam part 96
is arranged as a direct continuation of the separating cam part 112 in the preceding system section 107 in the free space formed between. As long as this additional cam part 119 does not interfere with other cam devices, it is of course possible to arrange this cam part in that device as well (FIG. 16).

Preceding system partition 107 and subsequent system partition 10
8, it is possible to realize the ternary law,
For this purpose, the needle 3 selected in the first system section 107 by the selection device 22a is placed in the normal capture position 109.
The other needles 3 are left in the passing track. Affiliated intermediate pusher 58 to its bat 5
9 is immediately lowered into the passing track by the cam part 120 of the first system section 107 after reaching the high capture position, so that when entering the second system section 108 it is again subjected to the selection process. Occupy the required position. In this way, all the needles 3 can be selected anew by the selection device 22b. The intermediate pushers 58 of the non-selected needles 3 are moved into the passing track, and the intermediate pushers 58 of the selected needles 3 are first raised to a high catching position and then the separation cam part 98
is transported to the knitting position by First system division 1
Needle 3 transferred to normal capture position 109 in 07
is pulled down 6 with the fully pushed out needle 3 as implied for the needle butt 6c in FIG.
It also passes through the second system section 108 at that location before being transferred. Furthermore, in this case, not only the needles 3 coming from the rotating track, but also the needles 3 that have been lifted into the normal capture position 109 in the preceding system section 107,
It is possible to select for organizing operations.

FIG. 14 shows tracks corresponding to the tracks of FIGS. 4 and 9, which are assigned to the cam arrangement shown in FIG. a track 122 for reciprocating the insert/pull-out plate 5 and a track 12 drawn in solid lines for the needle 3 pushed into the knitting position.
4 and the dotted trajectory 125 for the needle 3 pushed into its normal capture position.

In both system sections, during the selection process the needle 3 is pushed up to the high capture position 126 from where it is then started to be lowered into the passing position again.
It can be pulled down to the normal capture position 127 or pushed out to the knitting height.

The various knitting tools, in particular the previously mentioned needles 3, needle pushers 14, sliders 47 and intermediate pushers 58, can be pushed into a high gripping position during the selection process, preferably with a direct drive and also in the first position. As shown in FIG. 8, the knitting process is carried out in such a way that empty processes are never performed using the various knitting tools. Therefore, if the device and arrangement described above are adopted, it becomes possible to arrange 96 system sections along the periphery of a circular knitting machine with a diameter of 30" instead of 72 system sections as in the past. These system divisions are exclusively used as unique compilations or systems that apply the ternary method.When implementing the ternary method consistently, this system division consists of 48 systems as shown in Figures 13 and 14. By forming a knitting system, it is possible to form a large number of different patterns or to create a wide variety of combinations of patterns each time.

In this case, each cam part of the insert/pull-out plate 5 has a track 31, 32 according to FIG. 4 and a track 77, 7 according to FIG.
8 and the trajectories 122, 123 according to FIG. 14, it is clear that they can always be constructed as equivalent, regardless of the desired pattern in each case.

Furthermore, according to the present invention, in order to simplify the arrangement change of the knitting machine required when changing the pattern, the cam part jacket 8 according to FIG. 1 is replaced with a plurality of mutually equal segments 131 and 16 according to FIG. It is proposed to consist of a plurality of exchange plates 132 to 136 according to Figures (1 to 1). In this case, each segment 131 is in each case from one carrier, and in the lower part of this carrier there is a In such a combination of cam parts, the needle pusher cam part 15, which is equal to one another, and the pivot part or similar element, not shown in detail, for the needle pusher 14 are fixed and, if necessary, are also in the same system section or below. Selection device 2 for system partitioning as described in
2 is also fixed. Note that these selection devices 22 can alternatively be fixed to a certain cam plate. The upper part of the segment 131 contains all the cam parts required for controlling the insert/pull-out plate 5, in particular the cam part 3 of the butt 9 in the insert/pull-out plate 5.
A cam portion 29 that forms 0 or moves it up and down.
a and 29b are fixed appropriately. Insofar as described above, each segment 131 can be constructed as completely equivalent.

The central section of each segment 131 has a replacement plate 132
~136 and is provided with threaded holes 138 for fixing screws, these fixing screws being
To secure the replacement plates 132-136, they are inserted into holes 139 drilled in each plate. in this case,
Both screw hole 138 and hole 139 are connected to segment 13.
Since they are provided on the same side of the exchange plates 1 to 132 to 136, it is possible to fix each exchange plate to an arbitrary segment 131, respectively.

Each exchange plate 132 to 136 has a needle 3, a slider 47, and an intermediate pusher 58 on its surface, respectively.
It is equipped with the cam part required for this purpose. The exchange plate 132 (FIG. 16(a)) is used for selecting rotation, knitting or knitting, and has a cam part according to FIG. 11 and additionally a cam part 119. Replacement plate 133 (16th
Figure (b)) is used to select rotation and capture when applying the ternary method, and system classification 1 according to Figure 13.
It is equipped with a cam portion corresponding to 07. Replacement plate 13
4 (FIG. 16(C)) is used to select rotation and capture when applying the binary method, and is a cam section 119 shown in FIG. 13 supplementary to the cam section according to FIG. 10. It is equipped with Furthermore, an exchange plate 135 (FIG. 16(d)) is used for selecting acquisition and formation and is provided with a cam part according to FIG. 7 and, supplementarily, a cam part 119 according to FIG. 13. Finally, the replacement plate 136 (Fig. 16(e))
is used to select left, right, and plain knitting, so the cam part 1 shown in Fig. 13 is supplementary to the cam part shown in Fig. 12.
It is equipped with 19.

As already mentioned, the supplementary cam portion 119 is located at any location (
(FIG. 13), it can also be placed anywhere as long as it does not interfere with other desired controls. In this case, for example, the cam device according to FIGS. 10 and 11 includes:
This cam portion 119 is provided as the base [1] in order to prevent serious trouble from occurring even if the system sections 107 and 108 are mistakenly mixed up when assembling the cam device according to FIG.

The present invention is not limited to the embodiments described above, but can be implemented in various different ways. For example, this already applies to German Patent Application No. 274
It is known from specification No. 6720, but the insert/
The drawer plate can be pivotably mounted in a horizontal disk-shaped carrier separate from the needle cylinder. It is also possible, if desired, to arrange another knitting tool between the needle and the needle pusher 14, which acts as a selection element. Furthermore, as a yarn feeding method for the needle pushed out to the knitting position or the catching position, the circumference 4. Since any known method can be used as desired, the description of the yarn feeding device is omitted in this specification to avoid complexity.
