Description

[Technical field]

[0001] The invention relates to a textile tool part pair consisting of two textile tool parts, which are designed to be inserted into the respective seat (bed) of a textile processing machine. In particular textile tool parts, for example knitting tool parts, are used during loop formation, loop transfer or yarn manipulation during textile production. The textile tool parts are inserted into the tool seat of the textile processing machine or, for example, into a groove-like guide channel of a knitting machine. The textile or knitting tool parts are arranged in a movable guide manner along the guide channel. The two textile tool parts of a common textile tool part pair can each be a complete textile tool or can be formed together as one textile tool. The textile tools can be, for example, sinkers, transfer or transfer needles, knitting needles, for example latch needles, warp knitting needles, sliders for sliding needles, sewing needles or other textile tools used during loop formation or loop transfer. [Background technology]

[0002] Textile tools, in particular knitting needles, for use during loop formation in textile processing machines are known to come in many forms. For example, US Pat. No. 5,399,433 describes a transfer needle for the transfer of a loop from a needle to an adjacent needle.

[0003] A textile tool for flat knitting machines is described in DE 10 200 03 336 A1. The textile tool consists of two flat parts connected to each other.

[0004] DE 10 200 03 133 A1 proposes producing a yarn-guiding textile tool for a knitting or warp knitting machine by stamping and bending, whereby two webs of the textile tool are stamped and subsequently placed on top of each other or folded alternately.

[0005] The method of US Pat. No. 5,399,633 shows the production of textile tools, in the example sinkers, by stamping from a metal strip having portions of different thickness.

[0006] In the case of a textile tool part with a stepped thickness, known from DE 10 200 03 133 A1, two parts with a constant thickness but different contours are produced and subsequently placed transversely to one another.

[0007] In the sinker pair described in Patent Document 6, the thickness of the two sinkers of the sinker pair is reduced and they are inserted together into a channel of a sinker cam.

[0008] Patent document 7 discloses a textile tool, and in the embodiment, a knitting needle is disclosed. The textile tool has a number of parts supported so as to be movable relative to each other. The two parts are connected to each other by a joint between the members, and during the first use in the machine, the connection is broken, simplifying the handling so that the two parts can be moved relative to each other.

[0009] Patent document 8 discloses a textile tool part pair having the technical features described in the preamble of claim 1. The two textile tool parts are connected to each other in their facing planes by a material connection. The material connection can be broken by manual means. For example, the connection can be formed by glue or varnish.

[0010] Patent document 9 discloses a textile tool for knitted products, which consists of two integrally manufactured parts, which are brought into contact with each other by folding an initial body to produce the textile tool. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] International Publication No. 2009 / 095359 [Patent Document 2] European Patent Application Publication No. 2767626 [Patent Document 3] DE 102014103261 A1 [Patent Document 4] German Patent Application Publication No. 69311629 [Patent Document 5] European Patent Application Publication No. 2128319 [Patent Document 6] DE 102013104189 A1 [Patent Document 7] German Patent No. 10148196 [Patent Document 8] European Patent Application Publication No. 1486600 [Patent Document 9] U.S. Patent No. 2,696,721 Summary of the Invention [Problem to be solved by the invention]

[0012] The object of the present invention is to improve the production and / or handling of textile tools based on the prior art. [Means for solving the problem]

[0013] This object is solved by a textile tool part pair having the technical features of claim 1. Also proposed is a method for assembling a textile processing machine with the technical features of claim 12, in which method a textile tool part pair according to the invention is used.

[0014] In the present invention, a textile tool part pair consists of two textile tool parts. The two textile tool parts can be identical, have the same external shape or be symmetrical with respect to a plane of symmetry extending at the connection between the two textile tool parts. Each textile tool part preferably extends in the longitudinal direction between a front end and a rear end. Furthermore, each textile tool part has a working part configured to contact the yarn during loop formation or during the movement or transport of the loop or to accommodate another operation during textile production. The working part may be directly adjacent to the front end. The working part is arranged at a distance to the rear end.

[0015] The two textile tool parts of a common textile tool part pair are connected to one another at or by their rear ends by a predetermined connection disconnection, which can be separated manually without the use of tools. The predetermined connection disconnection is separated, e.g. split, by bending around a bending axis perpendicular to the longitudinal direction. After the two textile tool parts have been separated, they can be inserted separately or together into a textile processing machine and used. As long as the predetermined connection disconnection is established, the two textile tool parts have a relative position or orientation that does not correspond to a relative position or orientation required during use in the textile processing machine. In particular, the insertion of the textile tool parts into the textile processing machine is not possible as long as the predetermined connection disconnection is established.

[0016] The two textile tool parts can be manufactured together as an integral part. This is advantageous especially for very small textile tool parts, since it simplifies the handling during the manufacture of very long parts, i.e. integral textile tool part pairs. This allows for increased efficiency during production, since the two textile tool parts can be transferred to and received from a processing station or processing centre at the same time. Furthermore, the manufacturing precision of two textile tool parts which cooperate in a textile processing machine can be increased, since the relative position between the two textile tool parts being processed during manufacture is known, and therefore the functions of the textile tool parts can be set very precisely to the arrangement of the functions of each of the other textile tool parts. This also increases the manufacturing precision and reduces post-processing or adjustment requirements during use.

[0017] Furthermore, handling can be significantly simplified during assembly of the textile processing machine. Cooperation of textile tool parts or textile tool parts that are always used in pairs, for example knitting needles with different foot positions or asymmetric needles used in pairs, is known for example from EP 3124664 A1 and can be arranged as textile tool part pairs with a defined connection disconnection. In this way, two textile tool parts forming a pair can be handled in the same way until they are inserted into the textile processing machine. Errors due to the insertion of mismatched textile tool parts can be avoided in this way.

[0018] Advantageously, a given connection break comprises at least one web extending between two rear ends of the textile tool parts, the at least one web having a smaller cross-sectional area, e.g. thinner in the transverse direction and / or shorter in the height direction, compared to the adjacent rear ends of the textile tool parts, the height direction and the transverse direction being respectively perpendicular to the longitudinal direction and oriented perpendicular to each other and forming, together with the longitudinal direction, a Cartesian coordinate system.

[0019] The at least one web is preferably constructed integrally with the two textile tool parts. The at least one web is therefore made of the same material as the two textile tool parts. In particular, the at least one web and the textile tool parts are made of a metal or a metal alloy, for example a steel alloy. The at least one web can be produced by a cutting process and / or a non-cutting forming method. For example, the at least one web can be produced by stamping or another cutting method and / or embossing.

[0020] In a preferred embodiment, at least one web extends between two opposing end faces of the rear end, the end faces being preferably oriented substantially perpendicular to the longitudinal direction, and extending in a plane defined by the height direction and the transverse direction.

[0021] The textile tool parts preferably extend in opposite directions from a given connection break to their respective front ends in a common longitudinal direction.

[0022] The predetermined connection break can be configured to allow bending of the textile tool part around a bending axis extending perpendicular to the longitudinal direction. The bending axis preferably extends in the height direction. Furthermore, the predetermined connection break can be configured to prevent bending around an axis parallel to the longitudinal and / or transverse directions, allowing for preference to bending around a bending axis extending in the height direction. The bending axis can for example extend parallel to the end faces of the two opposing ends.

[0023] Furthermore, it is advantageous if each of the two textile tool parts comprises a base surface extending along a common reference plane, which is preferably defined by a longitudinal direction and a transverse direction, so that the reference plane can be oriented perpendicular to the bending axis.

[0024] In a preferred embodiment, the reference surface is , Fiber The contact surface contacts the tool part from below. The substrate surface extends within the reference plane. In this condition, no portion of the fiber tool part or fiber tool part pair extends through the reference plane.

[0025] The base surfaces of the two fiber tool parts can be arranged at a distance from each other in the longitudinal direction. Each fiber tool part in particular comprises exactly one base surface, which is preferably configured continuously in the longitudinal direction without interruption. In some embodiments, the base surfaces can be separated by portions that are at a distance from each other in the longitudinal direction.

[0026] The substrate surface can be used as a support surface during handling of the fiber tool part pairs during the manufacturing process or after manufacture during shipping, thereby improving support of the fiber tool part pairs compared to individual fiber tool parts.

[0027] In a preferred embodiment, the two fiber tool parts are configured to be arranged opposite each other after the separation of the predetermined connection cut to form a common fiber tool. For this purpose, each fiber tool part may have an abutment surface. Before the separation of the predetermined connection cut, the two abutment surfaces are arranged at a distance from each other and preferably extend in a common plane. This common plane can be defined in the longitudinal direction and in the height direction. The two fiber tool parts may be sinker parts which together form a sinker after abutting each other.

[0028] The steps for assembling a textile processing machine are as follows:

[0029] First, a textile tool part pair according to one embodiment described above is provided. The two textile tool parts of the textile tool part pair are then separated from each other at a predetermined disconnection section. The predetermined disconnection section is configured so that the separation can be performed manually, without tools. After the textile tool parts have been separated from each other, the textile tool parts are inserted into their operating position in a textile processing machine. In the operating position, the two textile tool parts may abut each other and together form a textile tool, for example a sinker, a transfer part or another textile tool. However, the two textile tool parts can also be inserted separately into different guide channels of a textile processing machine, in particular a knitting machine.

[0030] The separation of the two textile tool parts is preferably effected by bending about a bending axis which may extend parallel to the rear ends of the two textile tool parts, in particular parallel to the end faces of the two ends facing each other.

[0031] Advantageously, the textile tool part can be inserted into the textile processing machine or into the respective guide channel or into the respective tool seat without further post-processing, and possibly damaged parts or surfaces at the rear end are not removed, as they are not critical for the use of the textile tool part in the textile processing machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Figures 1 to 5 each show different embodiments of a textile tool part pair 15 consisting of exactly two textile tool parts 16. The two textile tool parts 16 of a textile tool part pair 15 are individually usable textile tools 17 or fit together to form two textile tool parts 16 which together form a textile tool 17. In the textile tool part pair 15 shown in Figures 1 and 2 respectively, the two textile tool parts 16 together form one single functional textile tool 17 after insertion into a textile processing machine, for example a sinker 18 (Figure 1) or a transfer section 19 for loop transfer. A sinker 18 formed from two textile tool parts 16 is shown diagrammatically in Figure 12 in a top view.

[0035] The two textile tool parts 16 in Figures 3 to 5, which differ from Figures 1 and 2, each already form an individual textile tool 17 and, according to the embodiment, form a knitting needle for a knitting machine, which in the embodiment shown here is configured as a latch needle 20.

[0036] The two textile tool parts 16 of each textile tool part pair 15 extend in a longitudinal direction L between a rear end 21 and a front end 22. Each textile tool part 16 contributes to textile production and in particular to loop formation, since it comprises a processing section 25 which comes into contact with the yarn during use of the textile tool part 16 in the respective textile processing machine, in particular during the loop formation process or during the transport or manipulation of the loop or yarn. In the processing section 25, the textile tool parts 16 comprise a hold-down edge 26 and a knock-over edge 27, respectively, which are arranged at a distance from each other in the height direction H and arranged substantially overlapping each other, for the formation of the sinkers 18 (FIG. 1). The hold-down edge 26 and the knock-over edge 27 extend, according to the embodiment, substantially parallel to each other in the longitudinal direction L and / or. The hold-down edge 26 and the knock-over edge 27 are opposite each other. They limit a holding space 28 which is open in the longitudinal direction towards the front end 22.

[0037] The textile tool part 16 extends in a height direction H at the processing section 25 between a lower edge 29 and an upper edge 30 to form the sinker 18. In the embodiment, the lower edge 29 and the upper edge 30 are oriented parallel to each other. The lower edge 29 extends in a longitudinal direction L and also has an extension in a transverse direction Q perpendicular to the height direction H and to the longitudinal direction L. The lower edge 29 forms a base surface 31 of the textile tool part 16.

[0038] As can be seen from FIG. 1, the two base surfaces 31 of the fiber tool parts 16 of a common fiber tool part pair 15 extend in a common reference plane E defined by the longitudinal direction L and the transverse direction Q. Any part of , extending through the reference plane E Bina It is preferable that the reference plane E is ,under The contact surface of the embodiment contacts the edge 29 or the base surface 31 from below. The lower end 29 or the base surface 31 extends within the reference plane E.This has the advantage that both of the lower edges 29 or the base surface 31 of the common textile tool part pair 15 can be used as a common support surface during the manufacture of the two textile tool parts 16, for example during transport of the parts or during installation on the machine tool.

[0039] As is apparent from Figures 1 to 5, the working portion 25 of each textile tool part 16 is spaced apart from the rear end 21, and is preferably located closer to the front end 22 than the rear end 21. In some embodiments, the working portion 25 may be directly adjacent to the respective front end 22, for example the textile tool parts 16 (Figures 2 and 3) and the latch needles 20 (Figures 4 and 5) for forming the transfer portion 19.

[0040] In the working parts 25 of the textile tool parts 16 forming the transfer parts 19 there are respectively upwardly open loop holding recesses 34. The textile tool parts 16 are tapered towards the front end 22 and form, for example, transfer hooks 35 for forming the transfer parts 19 bent down below the loop holding recesses 34 (seen in the height direction H).

[0041] In the latch needle 20 shown in Figures 4 and 5, a needle hook 36 is arranged in the working part 25 where the front end 22 of the textile tool part 16 is located, respectively. The hook inner area of ​​the needle hook 36 can be opened by the latch 37 (as shown in Figures 4 and 5) or closed by rotating the latch 37.

[0042] Each textile tool part 16 comprises a drive part 40 between the working part 25 and the rear end 29. The drive part 40 is provided with a foot 41 protruding in a height direction H, which is arranged to cooperate with a cam in the textile processing machine and thus drive a textile tool, for example a sinker 18, a transport part 19 or a latch needle 20, to move it in a longitudinal direction L along a guide channel 42. The guide channel 42 is shown diagrammatically and by way of example in the sinker 18 in FIG. 12.

[0043] The textile tool part pair 15 in Fig. 1 is arranged at a distance from the reference plane E outside the lower edge 29 or base surface 31 of the working part. In the embodiment, the lower edge 29 or base surface 31 is directly adjacent to the front end 22. The two textile tool parts 16 are treated as a common textile tool part pair 15 during manufacture, so that the base surface 31 provides support against tilting.

[0044] In all fiber tool parts 16 of the fiber tool part pairs 15 of FIGS. 1 to 5, the reference surface E forming the contact surface is abutted from below against the base surface 31 of the fiber tool part 16, so that each fiber tool part pair 15 Any part of Extend through reference plane E Bina stomach.

[0045] The base surface 31 may be continuous in the longitudinal direction L (FIGS. 1-4) or may be separated into a number of portions by interruptions (FIG. 5). In the embodiment of FIG. 1, the base surface 31 is located near or directly adjacent the front end 22 and is a greater distance to each rear end 21 than to the front ends 22. In other embodiments, the base surface 31 may be located closer to the rear end 21 than to the front ends 22 (FIG. 3). In still other embodiments, the base surface 31 may extend substantially all the way from the front end 22 or at least from the working portion 25 to the rear end 21 (FIGS. 2 and 4).

[0046] At their mutually facing rear ends 21, the two textile tool parts 16 of a common textile tool part pair 15 are connected to one another by a predetermined connection disconnection 45. The textile tool part pair 15 is thus unitary and thus the two textile tool parts 16 of a textile tool part pair 15 are manufactured and transported together as one unitary piece. The predetermined connection disconnection 45 is only separated immediately before placement of the textile tool parts 16 on the textile processing machine.

[0047] The two fiber tool parts 16 of a common fiber tool part pair 15 may preferably be configured symmetrically with respect to a plane of symmetry S. The plane of symmetry may extend centrally between the two fiber tool parts 16 and may be oriented perpendicular to the longitudinal direction L.

[0048] In the embodiment of Fig. 1, the lower edges 29 of the textile tool parts 16 are of different lengths in order to make it possible to distinguish the textile tool parts 16 after separation. Alternatively or additionally, other geometric features and / or markings can also be provided, so that the two textile tool parts 16 of a common textile tool part pair 15 can be distinguished from one another. For example, a notch 44 or another marking can be introduced or placed in the foot 41 or in another suitable position of one of the two textile tool parts 16.

[0049] An embodiment of a predetermined disconnection portion 45 is shown in Figures 6-11. It is configured for manual disconnection without the use of tools. It is also possible to use tools for disconnection, but this is not required.

[0050] The predetermined connection break 45 is formed by at least one web 46 of the embodiment extending between the rear ends 21 of two textile tool parts 16. The at least one web 46 has a smaller dimension in the transverse direction Q and / or in the height direction H as two directly adjacent rear ends 21, which therefore has the disadvantage that separation or failure may occur. The dimension of the at least one web 46 is selected such that it can be separated or broken during assembly of the textile processing machine by an operator manually and without using tools.

[0051] In an embodiment, each rear end 21 of the textile tool part 16 has an end face 47, so that at least one web 46 extends between two mutually opposing end faces 47. In an embodiment, the end faces 47 extend parallel to the height direction H and can be oriented substantially perpendicular to the longitudinal direction L (FIGS. 7, 9 and 10) or obliquely inclined relative to the longitudinal direction L and / or the transverse direction Q, preferably with an angle between the end faces 47 and the longitudinal direction L of at most 20° or at most 10° deviating from the perpendicular angle.

[0052] The at least one web 46 is preferably constructed integrally with the two textile tool parts 16. Thus, the at least one web 46 has no joints or seams. The textile tool part pair 15 is preferably constructed integrally or manufactured integrally as a whole. The at least one predefined connection break 45 formed by the at least one web 46 in the embodiment can be formed by a chip removal process and / or a stamping process and / or a molding process. The at least one web 46 is preferably formed by a stamping and / or molding process (e.g. embossing) between the two rear ends 21 or between the two end faces 47.

[0053] As is evident from Fig. 9, one single web 46 can be provided, which extends between the two rear ends 29 or between the two end faces 47. Alternatively, it is also possible to provide several webs 46 which are arranged at a distance from one another in the height direction H. It is preferred that a given connection break 45 does not comprise several webs 46 which are arranged adjacent to one another in the transverse direction Q. If several webs 46 are provided, they are particularly preferentially arranged adjacent to one another in the height direction H.

[0054] The shape of the recesses or embossments between the two rear ends 21 or between the two end faces 47 for forming the webs 46 thinned in the transverse direction Q relative to the rear ends 21 may vary as shown diagrammatically in the examples of figures 6 to 8. The recesses or openings provided on the opposite sides of at least one web 46 in the transverse direction Q may have circular legs parallel or obliquely inclined to each other (for example, compared to figure 6). The recesses may alternatively have a rectangular cross section (figure 7) or another polygonal cross section, for example a trapezoidal cross section (figure 8).

[0055] In a preferred embodiment, the given connection break 45 is configured to define a bending axis A extending in the height direction H of the embodiment. During bending of the two textile tool parts 16 about the bending axis A, at least one web 46 of the given connection break 45 breaks and the two textile tool parts 16 separate from each other. The given connection break 45 or the at least one web 46 is preferably configured such that bending about an axis oriented parallel to the transverse direction Q or the longitudinal direction L is prevented. The sum of the heights of the at least one web 46, i.e. the sum of the heights of one single web 46 or the webs 46 of the present invention, is preferably greater than its dimensions in the longitudinal direction L and / or the transverse direction Q.

[0056] The bending of two textile tool parts 16 of a common textile tool part pair 15 about a bending axis A is shown diagrammatically in FIG. 11, where the bending axis A extends perpendicular to the drawing plane.

[0057] After the separation of the predetermined connection breaks 45, the breaks 48 or the fracture surfaces of the broken webs 46 remain at the respective rear ends 21 or respective end faces 47 of the two textile tool parts 16 (Figures 11 and 12). The textile tool parts 16 are inserted into the textile processing machine or respective guide channels 42 without further post-processing, as shown in Figure 12. The remaining breaks 48 or the fracture surfaces of the rear ends 21 are not critical for the use of the textile tool parts 16 in the textile processing machine. They are away from the processing part 25 and do not come into contact with at least one yarn during the production of textile. They also do not come into contact with the guide surfaces of the guide channels 42, so that no increased wear occurs due to the breaks 48 or the fracture surfaces of the failed webs 46.

[0058] When assembling the textile processing machine, at least one textile tool part pair 15 is taken from the stock, the two textile tool parts 16 are separated from one another by separating the predetermined connection disconnection parts 45, and the two textile tool parts 16 can be inserted into the assigned guide channels 42 without further subsequent post-processing.

[0059] In the embodiment shown in figures 1 and 12, the two textile tool parts 16, at least in the part arranged in the common guide channel 42, together form a sinker 18. For this purpose, each textile tool part 16 is provided with an abutment surface 49, the two abutment surfaces 49 abutting against each other to form the sinker 18 (figure 12). In the embodiment, the two abutment surfaces 49 extend at least along the drive part 40 of each textile tool part 16. Each abutment surface 49 is oriented parallel to the longitudinal direction L and the height direction H. The abutment surfaces 49 can in particular be configured without openings and can provide a two-dimensional contact between the two textile tool parts 16.

[0060] Also in the embodiment of FIG. 2, the two textile tool parts 16 are arranged to abut against one another at their abutment faces 49 to form the transfer section 19 . [Explanation of symbols]
