Description

The invention relates to a platinum set for knitting systems for the production of plush goods, in particular for use in circular knitting machines. A knitting system in the sense of this application comprises all the parts that are necessary to form a pair of stitches consisting of a basic stitch and a plush stitch.

For the production of plush eg knitting systems are used, as they are known from the DE 30 35 582 C2 , the DE 31 45 307 C2 or even the DE 41 29 845 A1 are known. These knitting systems each include at least one needle as well a circuit board with a slot-shaped recess directed transversely to the needle. Above the slot, the board has a transversely directed to the needle (Niederhalter-) nose, the upper edge is used to hold a plush hanger. The edge lying in the slot serves as a Kulierkante.

From the DE 30 35 582 this is a special solution, in which in addition to the slot provided with the board, a second board is provided, the flat side rests against the first-mentioned board. The second board has a projection which may partially obscure the slot of the first board. This can be changed by a relative displacement between the two boards, the effective slot length, for example, nachzuspannen plush loops when the associated needle is expelled.

The operation of such known knitting systems follows a common principle. By means of a suitable yarn guide base and plush yarn are supplied separately. The basic thread comes to lie in a conventional manner on the tee (Kuliere) of the plush board while the plush thread is on the said upper with respect to the Kuliere elevated platinum nose. Then the newly formed stitches, ground thread and plush thread are cut off together. This principle is followed both known embodiments with only one board per knitting system as well as systems with two boards per knitting system.

The height of the plush loops results from the distance between the Kuliere plush board to the inner edge of the hook of the (tongue) needle and thus from the dimensions of the plush boards used. Should the plush hanger height be changed? be, the plush boards must be replaced. This is associated with eg 4000 boards per circular knitting machine with a considerable effort.

From the prior art also special boards are known which allow an adjustment of the plush handle height. This is on the JP 2005-299056 A directed. This document discloses a motherboard with a cut edge and a pivotally mounted on the motherboard plush board whose nose is at a variable distance above the tee edge. The plush board is associated with an adjusting device, via which the pivot position of the plush board is defined adjustable.

The adjustment of the swivel position of the plush board is critical. If the swivel position is not the same for all knitting systems and plush boards, it will not be possible to achieve uniform plush goods. Rather, it would be expected with banding.

On this basis, it is an object of the invention to provide a way to adjust the plush loom height as desired on a knitting machine.

• Der erfindungsgemäße Platinensatz gestattet eine einfache Einstellung der Plüschhenkelhöhe. Dabei wird weder ein komplizierter Plüschplatinenschwenkmechanismus notwendig, noch müssen die Platinen einer Rundstrickmaschine ausgetauscht werden, wenn die Plüschhenkelhöhe verstellt werden soll. Erreicht wird dies, indem Platinenpaare bestehend aus Kulierplatine und Plüschplatine vorgesehen werden, wobei der Kulierplatine und der Plüschplatine unterschiedliche Führungsflächen eines Platinenbetts zugeordnet sind. Beide Platinen sind vorzugsweise gemeinsam in einem einzigen Kanal des Platinenrings angeordnet. Die Ansteuerung der Platinen kann in herkömmlicher Weise durch Platinenschlösser erfolgen, die auf die Füße der Platinen einwirken. Grundsätzlich genügt zum Antreiben eine gemeinsame Schlossbahn für beide Platinen. Die Platinen werden durch diese Schlossbahn in Platinenlängsrichtung synchron bewegt. Es ist alternativ möglich, zwei oder mehrere Schlossbahnen vorzusehen, um die Platinen getrennt ansteuern zu können, d.h. unabhängig voneinander in Platinenlängsrichtung vor und zurück bewegen zu können.

The invention is achieved with a platinum set according to claim 1:

• The platinum set according to the invention allows easy adjustment of the plush handle height. In this case, neither a complicated Plüschplatinenschwenkmechanismus is necessary, nor the boards of a circular knitting machine must be replaced when the Plüschhenkelhöhe be adjusted should. This is achieved by board pairs are provided consisting of sinker and plush board, the sinker and the plush board are assigned to different guide surfaces of a board bed. Both boards are preferably arranged together in a single channel of the sinker ring. The control of the boards can be done in a conventional manner by board locks, which act on the feet of the boards. Basically, it is sufficient to drive a common Schlossbahn for both boards. The boards are moved synchronously through this castle track in the board longitudinal direction. It is alternatively possible to provide two or more castle tracks to be able to control the boards separately, ie independently to be able to move back and forth in the board longitudinal direction.

With the inventive concept, it is possible to adjust the sinker and the plush board in a height direction with respect to each other. The height direction is understood to be perpendicular to the bottom of the channel of the sinker ring, ie parallel to the channel walls and transverse to the sinker longitudinal direction. Preferably, only the plush board is adjusted in height while the sinker is not adjusted. Accordingly, the plush board are associated with height-adjustable guide surfaces of the board bed, while the sinker guide surfaces are associated with the board bed, which are not adjustable in height. The adjustable guide surfaces are formed on correspondingly adjustable support elements. Thus, the height of the sinker can be adapted to the Nadelhub, which is usually not changeable. Due to the height adjustment of the plush board, the length of the plush loops and thus also the pile height of the plush to be produced can be adjusted.

The guide surfaces of the sinker bed are preferably adjustable support elements which are arranged in channels of the sinker ring or also by separate, e.g. arranged on the knitting cylinder elements are formed. The adjustable elements and their guide surfaces extend transversely to the channels in which the boards sit. Relative adjustment of the sinker and plush board can also be accomplished by relative displacement of the sinker ring and the knitting cylinder, e.g. when the sinkers are mounted on the knitting cylinder and the plush boards on the sinker ring.

The sinker and the plush board sit on the guide surfaces, preferably each with straight edges and slide on the guide surfaces. The leading edges are preferably oriented in the longitudinal direction of the board. The leading edges of the sinker and the leading edges of the plush board are preferably spaced apart longitudinally to engage the different guide surfaces of the sinker bed. Additionally or alternatively, the leading edges of the plush board may be inclined from the leading edges of the sinker in the height direction, i. be spaced apart transversely to the edge longitudinal direction. For a compact design of the guide elements can be achieved.

Preferably, at least one of the two boards is provided at the point with a recess where the adjacent board has a leading edge. In this way, it can be ensured that each board only comes into engagement with the respectively associated guide surface. Thus, they differ to the board set according to the invention associated sinkers of those of the prior art in that additional recesses are provided which prevent the plush boards associated height adjustment acts on the sinkers.

The two boards of the board set according to the invention are arranged together in a channel of the sinker ring. The plush board is not on the bottom of the guide channel but on at least one support part, which is adjustable in height. A second bearing may be formed by having a height adjustable support member e.g. engages in a frontal recess of the plush board.

The plush board can be formed with or without Niederhalternase. The individual elements of the height adjustment device can be arranged at different points of the circular knitting machine, for example on the platinum support ring and / or on the knitting cylinder.

The plush board and the sinker can in principle be connected to each other, wherein the connection allows a relative movement of the two boards, at least in the height direction. Preferably, however, the plush board and the sinker are in loose relation to each other. That they are not connected to each other but lie flat side on flat side together in the guide channel of the corresponding board bed (for example, the circuit board ring) and are held together by the walls of the sinker channel.

Further details of advantageous embodiments of the invention will become apparent from the description of the drawing or claims. The description is limited to essential aspects of the invention and other circumstances. The drawing is to be used as a supplement. It reveals more details.

In FIG. 1 is a knitting system for making a knitted fabric with plush illustrated. To the knitting system includes a needle 2, for example in the form of a latch needle. The needle 2 has a shaft which carries a hook 3 at the end. This is associated with a pivotally mounted tongue 4. The needle 2 is longitudinally in a needle channel 5 of a knitting cylinder 6, held vertically movable in the embodiment. Cylinder springs 7 hold the needle 2 in the respective needle channel.

The knitting cylinder 6 is associated with a sinker ring 8 having radially oriented channels 9 for receiving pairs of boards 10. The channel 9 delimiting radially and vertically oriented channel walls are present, but not shown. To each pair of boards 10 includes a sinker 11 and a plush board 12. The sinker 11 and the plush board 12 are flat sheet metal parts that abut each other with facing flat sides. They each have a drive foot 13, 14, which projects into a lock channel 15 of a board lock 16. A relative rotation of the sinker lock 16 against the sinker ring 8 about a vertical axis of rotation, which is concentric with the axis of rotation of the needle cylinder 6, leads to a synchronous movement of the sinker 11 and the plush board 12, the drive feet 13, 14 follow the non-circular lock channel 15.

The sinker 11 has at its in FIG. 1 lower narrow side a leading edge 17, 18, which is interrupted by a recess 19 and which faces the bottom 20 of the sinker channel 9. The bottom 20 forms a guide surface for the leading edge 17, 18. The sinker 11 slides in the longitudinal direction of the board 21, with the radial direction of the sinker ring 8 and with the longitudinal direction of the Leading edge 17, 18 matches, on the floor 20 back and forth.

The leading edge 17 may be formed so long that it passes by the needle 2 to slide, if necessary, on a further guide surface 22, which is formed for example on the upper annular end face of the needle cylinder 6.

The leading edge 17 may also be formed in two planes formed in parallel and level with each other.

The sinker 11 is not adjustable in height. Regardless of all the chosen settings, she works on the floor 20 sliding back and forth at the given height. Her provided at its front end upper edge 23 is used to chelly the knitted fabric.

The belonging to the pair of boards 10 plush board 12 is arranged vertically adjustable. For this purpose, in the sinker ring 8 a bottom 20 passing through channel 24 is arranged, which extends transversely to the sinker channel 9. In the channel 24, a height-adjustable support 25 is provided, whose upper side forms a guide surface 26 for the plush board 12. The plush board 12 has on its underside a straight guide edge 27 which can slide on the guide surface 26 in the edge longitudinal direction (arrow 21) going back and forth. The support 25 preferably remains at rest and determines the height position on which the plush board 12 slides. The actual leading edge 27 is that part of the lower narrow side of the plush board 12, which may come into contact with the support surface 26. The same applies with regard to the leading edge 17 with respect to the bearing surfaces 20, 22. The leading edge 27 of the plush board 12 may be formed as the leading edge 17 of the board 11 in two parallel formed in the height offensive levels.

The plush board 12 may have at its front, the head of the needle 2 adjacent the end of a longitudinal slot 28 which is bounded by two preferably straight edges 29, 30. This longitudinal slot 28 extends in the needle longitudinal direction. It serves as a storage slot for supporting the plush board 12 on a height-adjustable support 31, which is arranged for example on the front side of the knitting cylinder 6. The edges 29, 30 form guide edges, which are preferably associated with planar guide surfaces 32, 33 of the height-adjustable support 31. Between individual pairs of boards 10 can be provided on the support 31, in FIG. 1 Dashed lines indicated 47 may be provided between which the sinker 11 and the plush board 12 are taken.

How out FIG. 1 can be seen, the guide edges 17, 18 of the sinker 11 spaced from the leading edge 27 of the plush board relative to the sinker longitudinal direction 21. By contrast, the guide edges 27, 30 of the plush board 12 are spaced from the leading edge 17 of the sinker 11 in the height direction. The sinker 11 has adjacent to the leading edge 27 of the plush 12, the recess 19. The plush board 12 has in its end region, which is spaced from the drive foot 14, in the vicinity of the leading edge 17 of the sinker 11 a recess in the form of the slot 28. The sinker 11 has a slot 48 in its end region, which is offset from the drive foot 13. This slot 48 is larger in size than the slot Slot 28 of the plush board 12, preferably, it has a greater height. As a result, the support 31 which extends into the slot 48 can be adjusted in height without affecting the position of the sinker 11. The support 31 extends in addition to the slot 28 of the plush board 12 and can serve to adjust the height of this. The height of the slot 48 of the sinker 11 describe the movement space of the slot 28 in the vertical direction of the plush 12th

The plush board 19 has a plush nose 34 for temporarily receiving a half stitch for forming plush loops. By adjusting the height of the plush board 12 with respect to the sinker 11, the vertical distance of the upper edge of the plush nose 34 from the edge 23 and thus the size or length of the plush handle can be adjusted. The plush nose 34 additionally serves as a hold-down for the underlying fabric.

• In Betrieb wird die Nadel 2 vertikal auf und ab bewegt, wobei sie im ausgetriebenen Zustand jeweils einen Grundfaden und einen Plüschfaden aufnimmt. Mit dem Grundfaden bildet sie ein Gestrick, indem sie im Rückhub jeweils den Faden durch die auf dem Nadelschaft sitzende Halbmasche zieht, die ihre Auflage auf der Kante 23 findet. Den Plüschfaden legt die Nadel dabei auf der Plüschnase 34 ab.

The knitting system described so far operates as follows:

• In operation, the needle 2 is moved vertically up and down, taking in the expelled state, respectively, a background thread and a plush thread. With the background thread, it forms a knitted fabric by pulling the thread in each case through the half-stitch which is seated on the needle shank and finds its support on the edge 23 in the return stroke. The plush thread puts the needle while on the nose 34.

If larger plush loops are knitted, the plush board 12 must be adjusted upwards. This happens, in that the supports 25, 31 are moved vertically upward relative to each other relative to the knitting cylinder 6 and the sinker ring 8. To reduce the Plüschhenkel the pads 31, 25, however, adjusted vertically downwards. The adjusting movement is approximately parallel to the Austriebsbewegung the needle 2 and transverse to the longitudinal direction 21 of the boards 11, 12 directed.

FIG. 2 illustrates a slightly modified embodiment. The above description applies analogously based on the same reference numerals. In addition, it should be noted that the sinker 11 is provided with a dashed illustrated hold-down 35, which stands next to the nose 34. The hold-down 35 serves to prevent the rising of the knitted fabric when expelling the needle 2. This otherwise the plush nose 34 of the plush board 12 function is now transferred to the hold 35 of the sinker 11. As a result, larger Verstellhübe between the sinker 11 and the plush board 12 are possible without compromising their function.

A modified embodiment of the knitting system described above show the FIGS. 3 to 5 , In the following description, parts which correspond essentially to the above-described parts, in particular with regard to their function, will be given the same names and reference numbers, reference being made to the above description in addition to the following explanation.

In the embodiment according to FIG. 3 the plush board 12 is arranged in the board channel of the sinker ring 8 while the sinker or sinker 11 in corresponding, sits on the knitting cylinder 6 formed channels. In this embodiment, the sinker ring 8 takes over the function of the support 25 and the guide surface 26 takes over the function of the bottom 20. Preferably, the sinker 11 is positively held on the knitting cylinder 6. As a result, the sinker 11 is held stationary and has no drive foot. Such channels may extend, for example, starting from the end face of the knitting cylinder 6 via one of its wall surfaces. The baffle 11 serving to form the loop overlaps the working part of the plush board 12 in the vicinity of the needle 2 and the hook 3. The plush board 12 is preferably formed as a flat sheet which is laterally angled at the nose 34 and the adjoining part can. This measure can be used to the top edge 36 of the plush board 12, such as FIG. 5 shows, center between adjacent needles 2, 2 'and their hooks 3, 3 set'. The tee board 11 may, as in particular FIG. 4 shows, have a wide support portion 37 which bridges the distance between adjacent plush boards 12.

In this embodiment, the entire circuit board ring 8 may be height adjustable. Likewise, the board lock 16 may be synchronously adjustable in height to keep the distance between the board lock 16 and the board ring 8 constant. The sinker ring 8 can be mounted vertically adjustable by means of linear guides 38, 39. The linear guides 38, 39 can be arranged on a platinum carrier ring 40. To adjust the height, a height adjustment device 41 is then arranged, for example, between the platinum carrier ring 40 and the sinker ring 8. The platinum carrier ring 40 can be connected via a clamping device 42 with the needle cylinder 6.

Another modified embodiment illustrates FIG. 6 , This is basically based on the embodiment FIG. 1 or 2 , wherein reference is made to the corresponding description based on the same reference numerals. In contrast to the relevant description, however, the support 31 is not arranged on the knitting cylinder 6 but on the sinker ring 8. The support 31 engages with a corresponding projection in a slot 28 ', which is arranged at the rear end of the plush board 12. In contrast, the support 25 is arranged at a radial distance from the support 31, for example, at the end of the sinker ring 8 facing the knitting cylinder 6. While the plush board 12 is mounted with its leading edges 27, 29, 30 on the adjustable supports 25, 31, the sinker 11 is mounted with their leading edges 17, 18 with respect to the Austriebsrichtung the needle 2 stationary elements and surfaces 20, 22.

The adjustment of the plush size is done by adjusting the height of the plush nose 34 with respect to the edge 23 of the sinker 11 as described above.

Based on the above embodiments, another embodiment of the invention is possible in which the sinker 11 is driven by the plush board 12. Only the plush board 12 has the foot 14 while the sinker 11 is connected to the plush board 12 relative to the sinker longitudinal direction 21. In adjustment, which coincides with the Nadelaustriebsrichtung, the sinker 11 are moved against the plush board 12. This is made possible by linear guides, for example slide guides in the form of oblong holes 43, 44, which are provided in one of the boards, for example the plush board 12, while in these slots 43, 44 cross noses, pins or other projections 45, 46 with the sinker 11th are connected. The relative adjustment of the plush board 12 to the sinker 11 takes place here by height adjustment of the sinker 11 by means of the support 31. This engages in the slot 28 ', which is formed in this case on the sinker 11. Also by this measure, the plush handle height can be adjusted.

It is proposed a board set, which includes a sinker 11 and a plush board 12. The boards 11, 12 are movable together across a knitting needle 2. They have spaced-apart edges for receiving stitches. To adjust the distance of these edges, the boards 11, 12 are moved in Nadelaustriebsrichtung relative to each other. For this they have spaced guide edges 17, 18; 27, 29, 30, with different bearing surfaces or guide surfaces 20, 22; 26, 32, 33 are in contact.
