Description

Technical Field

[0001] The present invention relates to a coiling disk device for a spinning preparation machine, wherein the coiling disk device has a rotating disk, a cover plate and an opening edge, the rotating disk has a disk frame extending along a longitudinal axis and a base, the cover plate is arranged on the bottom side of the base extending transversely to the longitudinal axis, the opening edge surrounds a discharge opening constructed in the cover plate, the coiling disk device also includes a sliver channel for fiber slivers, which has an upper channel section surrounding an inlet and a lower channel section with an outlet arranged in alignment with the discharge opening, wherein the upper channel section is connected to the disk frame and the lower channel section passes through a through-opening in the base and is connected to the cover plate by a weld. The present invention also relates to a spinning preparation machine having at least one such coiling disk device and a method for manufacturing such a coiling disk device. Background Art

[0002] Such a spinning preparation machine with a coiling disk device is known, for example, from DE 10 2012 007 415 A1

[0003] Known. The sliver channel of a sliver coiling disk device is connected in the area of ​​its inlet to the disk frame of a turntable, which is made of aluminum or an aluminum alloy as a casting. The lower channel section of the sliver channel passes through a through-opening constructed in the turntable. In order to manufacture a sliver coiling disk device, it is proposed that the outlet of the sliver channel, for example, which consists of a stainless steel tube, is placed flush on the upper side of a closed cover plate. The sliver channel and the cover plate are firmly connected to each other by a welding process, such as laser beam welding. The laser beam penetrates the cover plate from the bottom and firmly welds the end surface of the sliver channel surrounding the outlet to the upper side of the cover plate. Subsequently, the discharge outlet of the cover plate, which is aligned with the outlet, is machined from the bottom side of the cover plate by a separation process. In addition, the sliver channel is cast in the through-opening of the turntable using a casting material.

[0004] DE 102004058572A1 discloses another kind of coiling disc device, wherein, on the cover plate made of stainless steel plate fastened on the rotating disc, a sleeve with a continuous opening is formed. The outlet of the sliver channel is fixed in the inlet of the sleeve and can be sealed, for example, by silicone resin, adhesive, etc. Summary of the invention

[0005] The object of the present invention is to improve a coiling disk device of the type mentioned at the outset so that it is simpler and more cost-effective to manufacture and damage to the fiber sliver is avoided. The object of the present invention is also to provide an improved spinning preparation machine having such a coiling disk device. The object of the present invention is also to provide a method which allows a coiling disk device of the type mentioned at the outset to be manufactured more efficiently.

[0006] This object is achieved by a coiling disk device of the type mentioned at the outset in that a weld is produced at the opening edge.

[0007] As a result, a continuously closed transition is provided between the cover plate and the sliver channel. The weld produced on the edge of the opening connects the lower channel section with the cover plate, preventing a narrow gap from being left between the sliver channel and the cover plate, which could damage the fiber sliver passing through. In addition, the positioning of the weld at the edge of the opening makes it possible to produce the weld using a welding machine that approaches the coiling disk device from below. The can turntable and the sliver channel are arranged above the cover plate, neither of which creates an obstruction below the coiling disk device. This allows for better access, which is advantageous both in manual welding and in the automation of the welding process. "Below" or "below" here refers to the arrangement of the coiling disk device during operation, when the fiber sliver is introduced into the sliver channel from above through the inlet and discharged through the outlet located below, so that it can be stacked, for example, in a storage area arranged below, such as a spinning can.

[0008] Furthermore, the weld can protrude radially inwardly from the longitudinal axis into the outlet opening. This actually reduces the outlet opening. However, the advantage is that the weld location is particularly accessible and a stable and durable weld can be produced between the two connection fittings, the strip channel and the cover plate.

[0009] The weld can be arranged outside the turntable along the longitudinal axis. The bottom side of the turntable on which the cover plate is arranged can define a plane. The turntable is arranged above this plane. The outlet opening formed in the cover plate can be located below this plane, and the weld is produced at the opening edge of the outlet opening.

[0010] The outlet and the outlet can both have an at least approximately elliptical or round, in particular circular, contour. The contours of the two openings (i.e. the outlet and the outlet) are identical, wherein in particular the area of ​​the outlet is larger than the outlet. This facilitates the attachment of the weld to the edge of the opening.

[0011] According to a first embodiment, it can be provided that the sliver channel is arranged so that the end surface of the following channel section abuts on or contacts the upper side of the cover plate facing the base. In other words, the sliver channel can be placed on the cover plate from above. This provides a particularly stable and durable coiling disk device, which is also simple to manufacture. In particular, the end surface refers to the end surface of the channel wall that ends the sliver channel. In addition, the discharge opening can protrude from the outlet laterally or radially with respect to the longitudinal axis. In other words, the discharge opening in the cover plate is larger than the outlet of the sliver channel on all sides. In particular, the end surface partially covers the discharge opening or partially overlaps with the discharge opening. In other words, in the radial direction with respect to the longitudinal axis, the outer section of the end surface can be supported on the upper side of the cover plate, almost forming a supporting section, and the inner section of the end surface protrudes from the discharge opening or overlaps with the discharge opening, almost forming an overlapping section. Therefore, a shoulder is formed between the end surface and the opening edge, and the weld is positioned or generated on this shoulder. By producing the weld at the opening edge and the end surface, in particular the overlapping section, the coiling disk device is particularly stable and durable. In addition, the end surface or its overlapping section preferably completely covers the weld, so that the weld does not protrude into the outlet through which the fiber strand can pass. This prevents damage to the fiber strand. In principle, however, the strand channel with the end surface can be completely butted against the cover plate and accordingly have no overlapping section.

[0012] According to a second embodiment (alternative to the first embodiment described above), it can be provided that the end surface of the lower channel section is in a plane which is opened or defined by the bottom side of the cover plate facing away from the base. In other words, the strip channel is flush with the bottom side of the cover plate on the outlet side. In addition, the lower channel section is inserted into the discharge outlet with a gap, so that a surrounding joining gap is formed between the lower channel section and the opening edge, and the welding part is positioned or inserted in the joining gap. In this way, the welding part can connect the opening edge with the outer wall of the strip channel or the lower channel section facing the switch edge. The position of the joining gap and the welding part are both located outside the outlet, thereby preventing damage to the fiber strip. In order to ensure that the joining gap for the welding part or the placement of the welding part is large enough, the gap can be at least 0.1 mm to a maximum of 1.5 mm.

[0013] The surface of the weld can be designed to be ground and / or polished, which applies to all embodiments. As a result, unevenness and roughness of the weld surface can be eliminated. This is particularly important to ensure that the fiber strip can pass through the strip channel without friction and without hovering or being damaged. In addition, possible cracks in the surface of the weld can be eliminated, making the weld more stable and durable. In addition, the surface of the weld becomes brighter, which improves the appearance, because the weld is visible when the coiling disk device is installed in the spinning preparation machine or when it is running, and the beautiful surface is an advantage.

[0014] The welded portion can at least partially form a continuous weld seam or individual weld spots. The welded portion preferably extends over the entire circumference of the opening edge.

[0015] In addition, the weld can be configured as an arc weld. Advantageously, it is particularly suitable for joining a cover plate (which can be made of a stainless steel plate, for example) with a strip channel (which can be made of stainless steel). In addition, the weld can be manufactured by an arc, so that the weld is precisely positioned on the edge of the opening and in an extended solution is positioned on a shoulder between the end surface of the strip channel and the edge of the opening or in a joint gap between the lower channel section and the edge of the opening. In addition, the thermal effect can be precisely controlled to prevent deformation of the joint fittings. In addition, the arc weld is very aesthetically pleasing, which is advantageous because the weld is visible when the cover is viewed from below. For example, the arc weld is a WIG (abbreviation for tungsten inert gas) weld. Alternatively, the weld can be manufactured, for example, by means of MIG / MAG (abbreviation for metal inert gas / metal active gas) welding, electrode welding, plasma welding, etc.

[0016] The sliver channel is preferably directly connected to the cover plate only by means of a weld produced at the edge of the opening. It is further preferred that there is no joining point between the sliver channel and the cover plate on the upper side of the cover plate facing the base. The weld produced from below provides sufficient stability so that the transition area between the upper side of the cover plate and the sliver channel, which is difficult to access from above due to space restrictions, does not require welding. This facilitates the production of the sliver coiling disc device.

[0017] Furthermore, it can be provided that there is no direct force-locking connection between the sliver channel and the base. It has been shown that the weld produced at the edge of the opening provides a sufficiently stable and durable connection between the two joint fittings. The lower channel section is also not welded to the base. Finally, the casting compound known from the prior art, such as a synthetic resin, for connecting the lower channel section to the base can be omitted. This also facilitates the maintenance of the coiling disk device, since the sliver channel is not cast. In addition, the coiling disk device is more ecologically sustainable, since it is easier to recycle. Casting compounds are also used in the prior art, because due to the spatial curvature of the sliver channel, the area obtained along the transition between the sliver channel and the cover plate cannot be reached from above with a welding torch. By positioning the proposed weld at the edge of the opening of the cover plate, a continuously closed transition can be constructed.

[0018] In order to prevent the sliver coiling device, which can be driven to rotate about the longitudinal axis during operation, from becoming unbalanced, balancing weights can be arranged on the base along the through-opening. This is advantageous, for example, if the sliver channel is not cast or there is no direct force-locking connection between the sliver channel and the base and the weight of the casting material is correspondingly missing. The balancing weight can be a single, continuous balancing weight or comprise a plurality of separate balancing elements that can be spaced apart from one another. The balancing weight can be made of a material whose density is higher than the material density of the base. The base or the turntable can be a casting, for example, made of aluminum or an aluminum alloy. The balancing weight can be made of, for example, alloy steel or an iron casting. The balancing weight can also be at least partially bonded, welded, screwed, etc. to the base. Instead of a balancing weight, a counter hole or cavity can also be constructed in the base.

[0019] In addition, the upper channel section can be arranged concentrically with the longitudinal axis and configured as a hollow cylinder. This facilitates the fiber strip from the upstream unit (e.g., a drafting device) to enter the strip channel. The upper channel section can be configured as a straight tube section. The disc rack can have a through hole extending along the longitudinal axis, into which the upper channel section is placed.

[0020] According to a first embodiment, the upper channel section can be connected to the chassis in a force-fitting manner, for example by means of an adhesive connection. This can be produced, for example, using a casting compound. According to a second embodiment alternative thereto, the upper channel section can be connected to the chassis by means of a further weld. Similar to the weld arranged on the outlet side, the further weld arranged on the inlet side also has good accessibility, since there are no protruding components above the chassis, so that the welding machine can also be easily accessible here.

[0021] The base and the tray frame can form a continuous component, which is surrounded by the turntable or is the turntable. The tray frame extends along the longitudinal axis. The base can be configured in a disk shape, and the cover plate is arranged on the bottom side of the base facing away from the tray frame.

[0022] The discharge port and the outlet can be arranged parallel to each other. In other words, the discharge port and the outlet can respectively open a plane, and these two planes are parallel to each other.

[0023] Furthermore, the object is achieved by a spinning preparation machine with a coiling device for depositing fiber sliver, in particular depositing it in a spinning can, in that the machine has at least one coiling disk device of the type described or of the invention. The same advantages are obtained with the spinning preparation machine as with the coiling disk device according to the invention, and vice versa, so that reference is made to the above description.

[0024] In particular, the spinning preparation device is a flat carding machine, a drawing frame, a combing machine, etc. A sliver coiling device can be arranged at the outlet of the flat carding machine in order to deposit the fiber sliver, in particular in a spinning can. In addition, the spinning preparation machine can have a drafting device and a depositing device arranged downstream of the drafting device in the direction of transport of the fiber sliver, which is used to deposit the fiber sliver, for example in a spinning can.

[0025] Furthermore, the object is achieved by a method of the type mentioned at the outset in the following manner: In order to produce the strand coiling disk device according to the invention, the following steps are provided: a cover plate is arranged on the bottom side of a base; a strand channel is inserted into a through-opening in the base; the strand channel is oriented so that the outlet is aligned with the discharge opening; the strand channel and the cover plate are connected by producing a weld point, wherein a welding torch of a welding machine approaches the cover plate along a longitudinal axis outside the base and welds the opening edge to the lower channel section.

[0026] Depending on the orientation of the various components of the coiling disk device during manufacturing, "below" or "beneath" can also be understood as downstream of the coiling disk device along the transport direction of the fiber strip through the strip channel, and "above" or "above" can also be understood as upstream of the coiling disk device along the transport direction of the fiber strip through the strip channel.

[0027] Neither the can carousel nor the sliver channel creates any obstruction below the coiling disc arrangement, so that the welding torch can easily approach the cover plate from below or along the longitudinal axis outside the base.

[0028] For the orientation of the sliver channel, a station with a recess can be provided. The turntable with the cover plate arranged thereon can be arranged on a first side of the station in such a way that when the outlet is aligned with the discharge opening, a second side of the station opposite the first side can be seen through the recess. This facilitates the orientation process.

[0029] If the sliver channel is oriented, it can be fixed. For this purpose, for example, a clamping device can be provided, which is fastened to a work station, for example. The sliver channel can also be fixed directly to the turntable. In particular, the upper channel section can be connected to the disc frame in a force-locking manner, for example, by an adhesive portion or at least one other welded portion. For this purpose, for example, a casting material (especially made of synthetic resin) can be filled into the intermediate space formed between the upper channel section and the disc frame, and the intermediate space can be designed in an annular shape. A sealing portion or a sealing ring can also be inserted in the intermediate space in advance. For example, for the other welded portion, a metal ring can be placed in the intermediate space and welded to the upper channel section on the radial inside. The metal ring can be connected to the disc frame on the radial outside, for example, by welding, gluing, or clamping.

[0030] For the orientation of the sliver passage, an image acquisition device can be provided, which is positioned outside the coiling disk device and is aligned with the discharge opening. In the case of a work station provided with a recess, the image acquisition device can be aligned with the coiling disk device through the recess. The image acquisition device can include one camera or multiple cameras.

[0031] The image acquisition device can be connected to an image output device. In this way, the acquired images can be displayed in real time on the image output device. The image output device can be a commercial screen. This allows the operator to continuously monitor the exit of the sliver channel and make adjustments to ensure optimal orientation.

[0032] The orientation process can also be automated. The image acquisition device can be connected to a robotic device that is configured to orient the sliver channel relative to the cover plate. In this way, the robotic device obtains a real-time image of the image acquisition device. For example, visual markings can be arranged on the lower channel section, in particular the end surface and / or the cover plate, which are observed by the image acquisition device during the orientation of the sliver channel and analyzed by the control unit of the robotic device. The robotic device can also be configured to produce welds and optionally further welds.

[0033] The weld can be produced by means of arc welding, in particular WIG welding. Other welding processes as already described above are also possible. The surface of the weld can be ground and polished.

[0034] A balancing weight can be arranged on the base along the through-opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] exist Figures 1 to 4 1 shows a coiling disk device 1 according to a first embodiment or individual details thereof. The coiling disk device 1 serves to deposit the fiber strands into a spinning can 2 and can be driven to rotate about its longitudinal axis 3 in a known manner for this purpose.

[0054] Figure 1 A section through a coiling disk arrangement 1 is shown, and below it a spinning can 2 is shown. The coiling disk arrangement 1 comprises a rotating disk 4, a cover plate 5 and a sliver channel 6, which has an inlet 7 and an outlet 8 for a fiber sliver (not shown). The fiber sliver thus passes through the sliver channel 6 in the direction from the inlet 7 to the outlet 8.

[0055] The turntable 4 is preferably a casting, for example made of aluminum or an aluminum alloy, and has a disc frame 9 extending along the longitudinal axis 3 and a disc-shaped base 10. An upper channel section 11 of the sliver channel 6 surrounding the inlet 7 is arranged in the center of the turntable 4 and connected to the disc frame 9. Specifically, the upper channel section 11 is arranged concentrically with the longitudinal axis 3 and is configured as a hollow cylinder. The disc frame 9 can have a through hole 12 extending along the longitudinal axis 3, in which the upper channel section 11 is inserted. The upper channel section 11 and the disc frame 9 can be connected to each other in a force-locking manner. For this purpose, when manufacturing the sliver coiling disc device 1, a casting material 14 is filled into the annular space 13 formed between the two connecting fittings 9, 11, in which a sealing ring (not shown) can also be arranged, and the casting material connects the connecting fittings 9, 11 to each other in a force-locking manner in a hardened state.

[0056] The lower channel section 15 of the sliver channel 6 surrounding the outlet 8 passes through the through-opening 16 formed in the base 10 without contact. There is no direct force-locking connection between the sliver channel 6 and the rotating disk 4 itself. The sliver channel 6 is directly connected to the cover plate 5 only in the lower channel section 15, that is to say via a weld 17.

[0057] Especially in Figure 2 As can be seen in FIG. 1 , a balancing weight 30 is arranged on the base 10 along the through opening 16. The balancing weight 30 can be bonded, welded, or screwed to the base 10 (eg, Figure 2 ) and equivalent connections or a combination of these connections. The balancing weight 30 is used to compensate for the imbalance of the winding disc device 1 that can be driven to rotate around the longitudinal axis 3. In this way, the balancing weight 30 can also compensate for the missing weight of the casting material commonly used in other cases. In addition, it has been confirmed that balancing with the help of the balancing weight 30 is significantly easier and more accurate than using a casting material. In particular, the balancing weight 30 is made of or composed of a material with a density higher than the material density of the base 10. The base 10 or the turntable 4 can be a casting made of aluminum or an aluminum alloy, for example. The balancing weight 30 can be made of alloy steel or iron castings, for example. In principle, in addition to the weld 17, the sliver channel 6 can also be cast in the through-opening 16, so that there is also hardened casting material in the through-opening 16 around the sliver channel 6 in the cavity 27 closed downward by the cover plate 5, but this is not necessary and is sometimes not conducive to production. For this case, the balancing weight 30 is not required.

[0058] The sliver channel 6 can be a hollow profile made of stainless steel, for example, and can have a wall thickness of approximately 1.0 mm to 4.0 mm. The fiber strand enters the upper channel section 11 of the sliver channel 6 via an inlet 7 arranged concentrically with the longitudinal axis 3 and leaves again via an outlet 8 arranged eccentrically with respect to the longitudinal axis 3 in the lower channel section 15 of the sliver channel 6. The middle channel section 18 of the sliver channel 6, which connects the two channel sections 11, 15, is spatially curved accordingly.

[0059] The cover plate 5 is arranged to lie against the bottom side 19 of the base 10 which faces away from the drum frame 9 and extends transversely to the longitudinal axis 3 and can be fastened to the base 10, for example by bonding and / or form-fitting. The edge 20 of the cover plate 5 can be bent upward and lie laterally against the base 10. The cover plate 5 is made of a stainless steel sheet, for example, and can have a sheet thickness of approximately 0.5 mm to 2 mm. The bottom side 21 of the cover plate 5 which faces away from the base 10 defines a first plane 22, in particular with which the coiling disk device 1 ends downwards, or in the direction from the drum frame 9 to the cover plate 5.

[0060] Especially in Figures 3 to 5 As can be seen in FIG. 1 , an outlet 24 surrounded by an opening edge 23 of the cover plate 5 is formed in the cover plate 5, and the outlet 24 is arranged overlapping with the through-opening 16 formed in the base 10. The outlet 8 is arranged aligned with the outlet 24. Both the outlet 24 and the outlet 8 can have a contour that is at least approximately elliptical, such as Figure 3 Their profiles are identical, with the difference being that the area of ​​the outlet opening 24 is larger than that of the outlet 8.

[0061] The lower channel section 15 has an end surface 25, with which the sliver channel 6 ends at its lower channel section 15. The end surface 25 together with the outlet 8 is in a second plane 26, which is parallel to the first plane 22 and is set back relative to the first plane toward the tray 9 (i.e. upward). The two planes 22, 26 can be arranged perpendicular to the longitudinal axis 3.

[0062] exist Figure 5 The enlarged view shows Figure 4 35. Specifically, the strip channel 6 can be butted with its end face 25 on the upper side 28 of the cover plate 5 facing the base 10 or in contact with the upper side. The outlet 24 protrudes laterally or radially from the longitudinal axis 3 beyond the outlet 8 defined by the inner wall 29 of the pipe, so that the end face 25 partially overlaps with the outlet 24. Accordingly, the radially outer section of the end face 25 (also referred to as the support section 31) is supported on the upper side 28 of the cover plate 5. The radially inner section of the end face 25 (also referred to as the overlapping section 32) protrudes from the outlet 24 or overlaps with it. Therefore, a shoulder 33 is formed between the overlapping section 32 of the end face 25 and the opening edge 23 of the cover plate 5, and the weld 17 is positioned or produced on this shoulder. Therefore, the weld 17 is arranged outside the turntable 4 along the longitudinal axis 3 and here protrudes inwardly into the outlet 24 radially from the longitudinal axis 33 in the area between the first plane 22 and the second plane 26. It goes without saying that during welding, the joint is always slightly melted, thereby forming the weld 17. Figure 4 and Figure 5A simplified illustration is depicted to illustrate the basic interrelationship of the components and their positional relationship to one another. The weld 17 remains concealed by the overlapping section 32 of the strand channel 6 in the transport direction 50 of the fiber strand. The surface 34 of the weld 17 is ground and polished.

[0063] exist Figure 6 , a flow chart of a method for producing a coiling disk device 1 is shown, starting with a starting stage 40 .

[0064] In step 41, the cover plate 5 is arranged and fastened on the bottom side 19 of the base 10. The strip channel 6 is placed from above flush on the top side 28 of the cover plate 5. For this purpose, the upper channel section 11 is inserted into the through hole 12 of the tray 9. The lower channel section 15 is passed through the through hole 16 in the base 10 and supported from above on the top side 28 of the cover plate 5.

[0065] In step 42, the sliver channel 6 is oriented such that the shoulder 33 is located between the overlap section 32 and the opening edge 23. For the orientation of the sliver channel 6, an image acquisition device 36 with at least one camera can be provided, which is located outside the coiling disk device 1. Figure 7 3 shows that the image acquisition device 36 is aligned with the cover plate 5 from below and the outlet opening 24 is in the field of view 49 of the lens of the image acquisition device 36. The field of view 49 is indicated by a dashed line. The image acquisition device 36 can be connected to an image output device 37 so that the orientation can be monitored in real time on the image output device 37 (e.g. a screen). This allows an operator or an assembler responsible for manufacturing the coiling disk device 1 to continuously monitor the orientation of the outlet 8 relative to the outlet opening 24 and to make adjustments in order to ensure an optimal orientation, in which the shoulder 33 has a shoulder width that is as constant as possible in the circumferential direction.

[0066] In step 43 , the sliver channel 6 is fixed in its oriented position relative to the turntable 4 .

[0067] In step 44 , the upper channel section 11 is connected in a force-fitting manner to the disk frame 9 . For this purpose, a bond can be produced in the annular space 13 formed between the disk frame 9 and the sliver channel, for example by injecting a casting compound 14 .

[0068] In step 45, the weld 17 is produced. Figure 8 3 shows that a welding device with a welding torch 38 is brought from below onto the shoulder 33 to produce the weld 17. The direction from below to the cover plate 5 or the shoulder 33 is Figure 7 and Figure 839 is provided in the figure. Depending on the welding process used, the welding torch 38 can be held obliquely to the direction 39 or parallel to it. Thus, the strip channel 6 and the cover plate 5 are firmly connected to each other by a welding process, for example an arc welding process. The weld 17 can be a circumferential or continuous weld seam. Since the strip channel 6 and the cover plate 5 can be composed of stainless steel, a problem-free weld can be achieved by arc welding.

[0069] In step 46 , the surface 34 of the weld 17 is ground and polished.

[0070] In step 47 , the coiling disk device 1 is balanced, in which the balancing weights 30 are mounted on the turntable 4 along the through-opening 16 .

[0071] The coiling disk device 1 is completed with the end phase 48 .

[0072] The order of the above steps can also differ from that described above. For example, the weld 17 can be produced before the sliver channel 6 is injected into the through hole 12 of the turntable 9. For another example, the balancing weight 30 can also be installed before the surface 34 of the weld 17 is ground and polished. In addition to these merely exemplary changes to the method, other technically reasonable sequences are also possible and conceivable.

[0073] Fig. 9 1 shows a coiling disk device 100 according to a second embodiment, which corresponds substantially to the coiling disk device 100 according to the first embodiment, so that reference is made to the above description with regard to similarities. The difference lies in the connection between the sliver channel 6 and the cover plate 5.

[0074] The end face 25 of the lower channel section 15 is in a plane 22 defined by the bottom side 21 of the cover plate 5 facing away from the base 10. The sliver channel 6 is therefore flush with the bottom side 21 of the cover plate 5 on the outlet side. In addition, the lower channel section 15 is inserted into the outlet opening 24 with a gap 102, so that a circumferential joint gap 101 is formed between the lower channel section 15 and the opening edge 23, in which the preferably circumferentially continuous weld 17 is positioned or inserted. The surface 34 of the weld 17 is ground and polished.

[0075] The coiling disk device 100 can be manufactured similarly to Figure 6 Here, too, the welding torch approaches from below in the direction 39. The weld 17 is positioned in the joint gap 101 and is produced on the opening edge 23 and the channel outer wall 51 of the sliver channel 6 facing the opening edge 23.

[0076] Fig.102 shows a third embodiment of a coiling disk device 200 which corresponds substantially to the coiling disk device 1 according to the first embodiment, so that reference is made to the above description with regard to similarities. The difference lies in the connection between the sliver channel 6 and the disk frame 9 of the turntable 4.

[0077] Instead of Figure 1 In the figure, the upper channel section 11 is injected into the through hole 12 of the disc frame 9 by means of a casting compound 14, and a plate 201 is provided, which is annular and can be arranged in the annular space 13. The plate 201 can be welded to the strip channel 6 radially inside with respect to the longitudinal axis 3 and to the disc frame 9 radially outside. The plate 201 is preferably a metal plate. In principle, adhesive bonds can also be provided instead of these additional welds 202, 203.

[0078] The coiling disk device 200 can be manufactured similarly to Figure 6 The method for manufacturing the coiling disk device 1 is different only in the implementation of step 44. The metal plate 201 is welded on instead of injecting the casting material 14. One or the welding torch 38 approaches from above in the direction 52.

[0079] Fig.11 1 shows a fourth embodiment of a coiling disk device 300 which is a combination of the coiling disk device 100 according to the second embodiment and the coiling disk device 200 according to the third embodiment, so that reference is made to the above description with regard to similarities. The sliver channel 6 is welded with its upper channel section 11 to the disk frame 9, such as in combination with the coiling disk device 100 according to the second embodiment. Fig.10 In addition, the strip channel 6 is welded with its lower channel section 15 to the cover plate 5 and the weld 17 is positioned in the joint gap 101, as shown in the combination Fig. 9 As described in the second embodiment of the present invention.

[0080] exist Fig.12 4 shows a spinning preparation machine 400 according to an embodiment of the invention, which has a coiling disk device 1 according to the invention. Fig.12 In the drawings, the coiling disk device is provided with the reference numeral 1 only by way of example, but it may also be the coiling disk device 100 or 200 or 300 .

[0081] The spinning preparation device 400 is shown here only as an example as a flat carding machine (e.g., a Truetzschler flat carding machine TC). The spinning preparation machine 400 has a winding device 402 for stacking the fiber sliver 401 in the spinning can 2 on the outlet side in the transport direction 50 of the fiber sliver 401. The winding device 402 includes a winding disk device 1, which can be driven by a drive (not shown) in a rotational manner around the longitudinal axis 3 of the winding disk device. When the can 2 located below the winding disk device 1 rotates at the same time in a known manner, the fiber sliver 401 is stacked in the can 2 in a cycloidal manner, so that the can 2 can be evenly filled with the fiber sliver 401.

[0082] The above-mentioned embodiments are only preferred embodiments of the present invention and do not limit the present invention in any way. Any person skilled in the art can make many possible changes and modifications to the technical principles of the present invention without departing from the scope of application of the technical principles of the present invention, by using the above-mentioned methods and technical contents or making equivalent modifications in an equivalent manner. Therefore, without departing from the content of the technical principles of the present invention, all equivalent modifications made based on the form, structure and principle of the present invention fall within the protection scope of the present invention.
