Description

Technical Field

[0001] This invention relates to a yarn guide holding device for guiding multiple yarns. Background Technology

[0002] In the production and handling of yarns, the running yarns are typically guided to maintain a defined yarn path. For this purpose, special devices are used to guide multiple yarns, also known herein as yarn guide holding devices, where the areas in contact with the yarns have specific abrasion protection. Especially in the case of synthetic yarns, a high-resistance contact surface is required, typically formed by guides made of ceramic materials. These guides, usually in the form of shaped components, are then held by a carrier. Such devices with multiple guides on a carrier plate appear, for example, in DE 2242362A1.

[0003] In known devices for guiding multiple yarns, ceramic guides are held on a carrier plate. For this purpose, the carrier plate has multiple slits on its longitudinal side, into which the guides are inserted. To secure the guides, the ceramic-formed components are typically held on the carrier plate by adhesive bonding. However, such adhesive bonding has a fundamental drawback: these adhesive bonds are detached by external forces, such as by pretreatment agents adhered to the yarns. As a result, the guides on the carrier plate completely fail.

[0004] In contrast, DE 20010219U1 discloses a yarn guiding device in which guides are held in a row on a support rail in a form-fitting manner. For this purpose, the guides have retaining portions that are connected to the yarn at one end of the support rail and pushed into the rail. However, the fundamental problem with this device is that, in order to replace one of the guides, it is usually necessary to remove multiple guides from the support rail beforehand. The sliding guidance of the guides is also particularly disadvantageous to their ability to occupy a fixed position for guiding the yarn. Summary of the Invention

[0005] Therefore, the object of the present invention is to develop and improve a general-purpose yarn guide holding device in such a way as to provide reliable holding of the yarn guide and user-friendly replaceability of the yarn guide.

[0006] This objective is achieved according to the invention by means of a yarn guide holding device.

[0007] A key feature of this invention is that the yarn guides are held in a form-fitting manner within two assembled plates, thus facilitating easy replacement. Multiple slots are formed within the plates to accommodate the yarn guides. Associated forks and stops allow the respective yarn guides to be secured without adhesive.

[0008] The yarn guide retaining device according to the invention is particularly suitable for melt spinning equipment, wherein multiple yarns are guided in the form of yarn bundles. In this case, these plates can be fixed in the machine frame, or they can be arranged to be movable in the machine frame by an actuator. Furthermore, the yarn guide does not need to be fixed with adhesive, resulting in the ability to replace broken yarn guides without the need for complicated adhesive removal.

[0009] According to one aspect of the invention, a yarn guide retaining device is provided for guiding yarn using a yarn guide, wherein the yarn guide is held in a yarn guide retaining slot of the yarn guide retaining device, wherein the yarn guide retaining device has a first plate and a second plate, the first plate and the second plate being positionable without adhesive between an installation position for inserting the yarn guide and a locking position for locking the yarn guide, wherein the yarn guide retaining slot in the locking position is formed by the first plate and the second plate.

[0010] Here, the installation position should be understood as the plate position of the corresponding slotted bags of two plates not forming a yarn guide to maintain the slotted bag position.

[0011] Here, the locking position should be understood as the corresponding slotted bags of two plates forming a yarn guide that holds the plate position of the slotted bags.

[0012] Locking here should be understood as holding the yarn guide in the yarn guide retaining slot with a precise fit, thereby guiding the yarn.

[0013] Advantageously, the yarn guide can remain in the locked position without adhesive. The omission of adhesive means no harmful solvents are released during installation, and when replacing a broken yarn guide, there is no need to remove any adhesive in a complicated manner using solvents or by melting the adhesive.

[0014] According to an exemplary embodiment of the yarn guide holding device, the first plate forms a top plate having at least one top fork tooth formed by a top slot bag that extends laterally into the top plate relative to the longitudinal direction, width direction and component depth direction.

[0015] Here, "plate" should be understood as a flat piece of rigid material that has substantially the same thickness throughout the process and is defined on two opposite sides by corresponding flat surfaces that extend precisely relative to the thickness.

[0016] According to an exemplary embodiment of the yarn guide retaining device, a longitudinal groove is formed in the top fork tooth and extends along the longitudinal direction of the component, such that a top locking stop is formed at the free-standing end of the top locking fork tooth.

[0017] According to an exemplary embodiment of the yarn guide retaining device, the top plate has a longitudinal groove that extends longitudinally in the top plate and is substantially complementary to the longitudinal groove of the top fork tooth of the top fork tooth.

[0018] Complementarity here should be understood as the longitudinal groove complementing the longitudinal groove of the top fork tooth, and extending in essentially the same direction.

[0019] According to one exemplary embodiment of the yarn guide retaining device, the top plate has a plurality of top forks and a plurality of top slots into which yarn guides can be inserted. The yarn guide retaining device then forms a comb-type yarn guide retaining device.

[0020] According to an exemplary embodiment of the yarn guide retaining device, the second plate forms a substrate that forms a base slot configured to correspond to the top slot of the first top plate, such that when the first top plate and the second substrate are positioned in a locked position, the top slot and the base slot together form a yarn guide retaining slot through which the yarn guide is locked in an adhesive-free manner.

[0021] According to an exemplary embodiment of the yarn guide retaining device, the top plate and the base plate have through holes and / or mounting openings configured to complement each other for mounting in the retaining device, and / or the top plate and the base plate are formed of metal, plastic and / or composite materials and / or the yarn guide is formed of ceramic material.

[0022] According to an exemplary embodiment of the yarn guide retaining device, the yarn guide has a U-shaped configuration and a web conforming to the U-shape, the web being configured on both sides and defining an installation channel for locking in the yarn guide retaining slot.

[0023] According to the present invention, this objective is achieved by a method for securing the yarn guide in a yarn guide holding device without adhesive.

[0024] According to another aspect, a method is provided for securing a yarn guide without adhesive in a yarn guide holding device according to one of the foregoing exemplary embodiments, the method comprising the following steps:

[0025] - Insert the yarn guide into the top slot of the top plate in a transverse direction relative to the longitudinal extension direction of the top plate;

[0026] - Push the yarn guide along the component depth direction of the top plate until it abuts against the surface of the longitudinal groove of the top fork tooth in the mounting channel and is arranged below the top fork tooth of the top plate;

[0027] - Lay the substrate on the side of the top plate opposite to the longitudinal groove of the top plate, such that the base groove of the substrate and the top groove of the top plate point in the same direction; and

[0028] - Displace the substrate in the lateral direction along the side of the top plate opposite to the longitudinal groove of the top plate until the base groove and the top groove form a yarn guide retaining groove.

[0029] This method provides a simple and reliable positioning and locking of the yarn guide in the yarn guide holding device. Attached Figure Description

[0030] The invention will now be explained in more detail with reference to the accompanying drawings and some exemplary embodiments based on the device according to the invention. The reference system XYZ shown in the drawings defines, in various cases, the extension directions of the components shown in the drawings of the comb-type yarn guide device in the longitudinal direction X, the width direction Y, and the depth direction Z of the components.

[0031] In the attached diagram:

[0032] Figure 1 An exploded view of the first plate and the second plate of a first exemplary embodiment of the yarn guide retaining device is shown;

[0033] Figure 2 It shows Figure 1 A cross-sectional view of the plate of the yarn guide retaining device shown in the intermediate step of installing the first plate and the second plate to fix the yarn guide; and

[0034] Figure 3 It shows that it is in Figure 1 A three-dimensional partial cross-sectional view of a yarn guide holding device used to maintain the locking position of the assembly plate of the yarn guide. Detailed Implementation

[0035] exist Figure 1 The diagram shows an exploded view of a yarn guide retainer 1, which includes basic components, a first plate 10 (hereinafter also referred to as a top plate) and a second plate 20 (hereinafter also referred to as a base plate). Both the top plate 10 and the base plate 20 have comb-like forks 11 and 21, which are respectively configured to be complementary to each other, such that they form associated slots 14 and 24 for inserting a yarn guide 30. In the assembled locked position, the slots 14 and 24 form a yarn guide retaining slot 140, the internal contour of which is configured to precisely mate with the mounting channel 32 of the yarn guide 30, such that the yarn guide 30 is locked in the yarn guide retaining slot 140 without adhesive.

[0036] For better understanding, the fork teeth of the top plate 10 are referred to as top fork teeth 11, and the fork teeth of the substrate 20 are referred to as base fork teeth 21. Through holes 26 and mounting openings 15, 25 are also formed in the top plate 10 and the substrate 20 to complement each other.

[0037] The through-holes 26 in the top plate 10 and the base plate 20 serve to save weight.

[0038] The function of mounting openings 25 and 15 is to adjust and fix the positions of the base plate 20 and top plate 10 relative to each other when the base plate 20 and top plate 10 are in the locked state, wherein the yarn guide 30 is fixed between the corresponding fork teeth 11, 21 in an adhesive-free manner. Through hole 26 can also be used for positioning and fixing purposes.

[0039] In addition to the base fork 21 of the substrate 20, the top fork 11 of the top plate 10 also has a top fork longitudinal groove 130, which defines a top locking stop 12 at the free end of the top fork 1. The top fork longitudinal groove 130 continues in a complementary manner to the top plate 10 via a top plate longitudinal groove 13 in the top plate, particularly for manufacturing reasons. In an embodiment not shown herein, the top plate longitudinal groove 13 is not formed in the top plate 10.

[0040] The dimension of the longitudinal groove 13 in the transverse direction Y of the component approximately corresponds to the height of the yarn guide 30 to be inserted in the transverse direction Y, so that the yarn guide 30 can be locked at the edge of the yarn guide 30 facing the top locking stop 12 at the free end of the top fork 11, and can be held in a fixed position without wobbling.

[0041] Unlike the top fork 11 of the top plate 10, the base fork 21 does not have an additional locking stop, but its depth in the Z direction is configured to substantially correspond to the total depth of the substrate 20.

[0042] Both the top plate 10 and the substrate 20 are made of metal. In various cases, the top plate 10 and the substrate 20 may also be made of plastic, composite materials or different materials, for example, the top plate 10 is made of metal and the substrate 20 is made of plastic.

[0043] The dimensions of the top plate 10 and the base plate 20 differ locally, at least in terms of component depth Z and component width Y, for example from Figure 2 and Figure 3 As can be seen, the corresponding component dimensions can also differ depending on the installation possibilities within the apparatus used to produce synthetic yarns.

[0044] Figure 2 The intermediate step of the final installation of the top plate 10 is shown, with the base plate 20 and the yarn guide 30 in the locked position A.

[0045] exist Figure 2 As can be seen in the cross-sectional view, the top fork 11 of the top plate 10 has a longitudinal groove 30, into which the yarn guide mounting channel 32 of the yarn guide 30 can be precisely fitted and at least partially inserted.

[0046] The yarn guide 30 is basically U-shaped. A retaining web 31 is constructed on both sides of the U-shaped profile of the yarn guide 30. The retaining web 31 defines an mounting channel 32, the external shape of which substantially corresponds to the internal shape of the yarn guide retaining slot 140.

[0047] The longitudinal groove 130 of the top fork tooth forms a recess 130 for the yarn guide mounting channel 32. The movement of the yarn guide 30 in the transverse Y direction of the component is also blocked by the top locking stop 12 and the bottom locking stop 141.

[0048] In order to fix the yarn guide 30 without adhesive, in the first step, the yarn guide 30 is inserted into the top slot bag 14, and then the yarn guide 30 is pushed against the longitudinal groove 130 of the top fork tooth as shown by arrow D. As a result, a part of the yarn guide mounting channel of the yarn guide is exposed, so that the base fork tooth 21 of the substrate 20 can be introduced into the yarn guide mounting channel 32.

[0049] This requires that the corresponding forks of the top plate 10 and the base plate 20 be oriented parallel to each other, and that their outer surfaces interact in such a way that the top slot 14 and the base slot 24 can form a common yarn guide retaining slot 140. The yarn guide 30 is fixed in place by the elastic clamping action of the two plates 10, 20 and locked by the associated stops and forks. As a result, adhesive-free fixing of the yarn guide 30 can be achieved, and any broken yarn guide 30 can be replaced without the need for complicated adhesive removal.

[0050] Then the substrate 20 is placed on the side of the top plate 10 opposite to the longitudinal groove 13 of the top plate, so that the base groove 14 of the substrate and the top groove 24 of the top plate point in the same direction.

[0051] This is followed by the substrate moving V in the lateral direction Y along the side of the top plate 10 opposite to the longitudinal groove 13 of the top plate, until the base slot 24 and the top slot 14 form a yarn guide holding slot 140.

[0052] Figure 3 The locked state A of the top plate 10 is shown, wherein the base plate 20 and the yarn guide 30 are fixed by these plates in the yarn guide holding slot 140 having the locked position A.

[0053] It can also be seen that the through hole 26 and the mounting openings 15, 25 are configured to correspond to each other, which also applies to the top slot 14 and bottom slot 24 of the top plate 10 and the substrate 20.

[0054] In this locked position state, the yarn guide retaining device 1 can be installed in a predetermined installation position of the winder and / or the device for producing synthetic yarn.
