Description

Technical Field

[0001] This invention relates to a carding machine for manufacturing a fiber web from fibrous materials, comprising at least one cylinder supported about a rotation axis, side guards fixedly mounted on a frame at positions on both sides of the cylinder, and at least one cover device disposed on the side of the cylinder. Furthermore, the invention relates to such a carding machine as described above, which also includes a sliding cover plate movably guided on or adjacent to the upper edge of the cover device. Background Technology

[0002] According to existing technology in the textile field, it is known that in spinning preparation machines (such as carding machines) used to process cotton, chemical fibers, or the like, baffle elements in the form of inner covers are installed on the side guards located at the ends of the carding rollers or cylinders. These baffle elements can be made of hard plastic, wood, steel, or aluminum. The conventional approach to secure such inner covers to the machine's side guards involves the use of numerous parts, brackets, and fastening accessories. This results in the disadvantage that such fastening is cumbersome and expensive in actual assembly.

[0003] DE 1139413A1 discloses a segmented side guard plate for a cylinder on a carding machine.

[0004] CN 206109626U shows a one-piece sidewall panel of a cylinder fastened to a frame.

[0005] EP 1686204B1 discloses a housing of a carding machine, wherein various segments are configured to be movable relative to each other. US 2004 / 0065046 discloses a movable side part of a housing of a carding machine having an upwardly pivotable front. Summary of the Invention

[0006] Accordingly, the object of the present invention is to improve a spinning preparation machine or a fiber web making machine by providing an inexpensive and easy-to-operate cover or shroud adjacent to the end side of the associated carding roller in its lateral region and / or above.

[0007] The carding machine according to the invention is used to manufacture a fiber web from fibrous material, and includes at least one cylinder configured to be supported about a rotation axis. Furthermore, this carding machine includes side guards disposed on both sides of the cylinder and fixedly mounted on a frame, and at least one cover device disposed on the side of the cylinder.

[0008] This invention includes the following technical teaching: the cover device is connected to the side guard plate by means of a fastening device. Here, the fastening device is constructed in a rim shape such that it extends at least along an annular section about the rotation axis of the cylinder. The fastening device is preferably made of metal, such as aluminum or stainless steel sheet or stainless steel.

[0009] According to another embodiment, the present invention includes the following technical teaching: the cover device consists of a plurality of planar segments arranged in a ring around the rotation axis of the cylinder.

[0010] This invention is based on the key understanding that, due to the rim-shaped construction of the fastening device and its extension at least along an annular section about the cylinder's axis of rotation, a cover assembly that can be easily and flexibly disassembled with a reduced number of associated parts can be provided. The fastening device can be cast onto the side guard plate or fastened to the side guard plate as a separate one-piece or multi-piece component. In this case, since the cover assembly is composed of multiple planar sections arranged annularly about the cylinder's axis of rotation, the advantage of simplified assembly is also achieved, especially when these planar sections are individually adapted to their adjacent rim-shaped fastening devices.

[0011] Furthermore, because the cover assembly consists of multiple planar sections, it offers the advantage that, for example, only specific planar sections can be disassembled in case of damage to the planar sections and / or for the purpose of maintaining the carding machine. This simplifies operations when maintaining the carding machine or repairing damaged planar sections of the cover assembly compared to conventional cover assemblies that typically have a larger size or area. When disassembling the carding machine, the rollers (cylinder, transfer, or stripping rollers) are moved along with the associated frame, allowing the associated components of the cover to be moved together without disassembly. Then, only the cover component containing the roller or frame to be maintained needs to be removed.

[0012] In an advantageous extension of the invention, at least one notch is formed on the radially outer edge of the fastening device, the size of which is adapted to the adjacent machine element of the carding machine. In this way, the fastening device can "not block" such an adjacent machine element, but rather allow the machine element to extend at least partially through the notch if necessary. As a result, a space-saving connection of the cover device to the side guard plate of the carding machine is achieved by means of the fastening device.

[0013] The purpose is that the cover assembly is connected to the associated fastening device by means of countersunk screws. The flat head of the countersunk screw has the advantage that adjacent machine parts of the carding machine will not come into contact with each other, and operational malfunctions will not occur when manufacturing the fiber web from the fibrous material. In this case, it is also advantageous that excessive accumulation or buildup of fibrous material does not occur on the flat head of the countersunk screw.

[0014] According to an advantageous extension of the invention, the assembly of the flange-shaped fastening device on the side guard plate of the carding machine can be simplified or optimized in that the fastening device consists of multiple ring segments, each connected to a side guard plate. This assembly of the ring segments on a side guard plate can either be achieved at one end of the cylinder, i.e., along an extension of the cylinder's rotation axis, or alternatively, from a direction extending in the plane of the side guard plate.

[0015] According to an advantageous extension of the invention, the carding machine has multiple cylinders, each supported about a rotating shaft, wherein a cover device is assigned to one side of each cylinder, the cover device being connected to the side guard plate of the respective cylinder by means of a flange-like fastening device. This provides the advantage that even with multiple cylinders, the carding machine can be effectively isolated or enclosed relative to the environment, so as to effectively prevent contaminants from entering from the outside and prevent fibrous material from "flying" out of the machine area and into the environment of the carding machine.

[0016] In an advantageous extension of the invention, it can be specified that these shroud devices and / or their planar segments, which are adjacent to each other, are connected to each other along their edge regions. This not only achieves the advantage of improving the overall stability of multiple planar segments of a shroud device and / or multiple shroud devices, each assigned to a cylinder of the carding machine and adjacent to each other, but also achieves the advantage of improving the sealing of the carding machine relative to the environment.

[0017] According to the invention, the connection of adjacent planar sections of a cover device or the connection of planar sections of different adjacent cover devices can be achieved by a connecting strip with slots formed on opposite sides of the connecting strip, into which the edge regions of the adjacent planar sections of the cover device can be inserted. In this case, the fit dimensions between the slots and the planar sections have an appropriate interference fit, thereby ensuring the stability of the planar sections within the slots. However, this clamping of the edge regions of the planar sections within the slots only provides a predetermined maximum force, and beyond this maximum force, the edge regions of the planar sections may slip or move significantly within the slots of the connecting strip. In this way, over-tensioning of a cover device and its planar sections and / or of multiple adjacent cover devices can be effectively prevented.

[0018] In an advantageous extension of the invention, compensation positions can be provided between corresponding planar sections of the cover assembly adjacent to each other on the end side of the cylinder. This ensures that, in particular, length compensation between adjacent cover assemblies can be achieved during temperature changes, so that when such temperature changes occur during the operation of the carding machine according to the invention, the cover assembly and its planar sections will not become over-tensioned or even break.

[0019] In an advantageous extension of the invention, a sliding cover may be provided, which is movably guided on or adjacent to the horizontal upper edge of the cover assembly. The movable guidance of the sliding cover is achieved by a sliding system disposed between the upper edge of the cover assembly and the sliding cover, the sliding system having a clamping bar and a sliding bar. Here, the clamping bar is secured to the upper edge of the cover assembly, wherein the sliding bar is connected to the sliding cover and slides in contact with the clamping bar located below it.

[0020] Another embodiment of the carding machine according to the invention includes a sliding cover plate that is movably guided on or adjacent to the upper edge of the cover assembly. This embodiment of the invention incorporates the following technical teaching: a sliding system disposed between the upper edge of the cover assembly and the sliding cover plate is provided with a clamping strip and a sliding strip, wherein the clamping strip is fastened to the upper edge of the cover assembly, and wherein the sliding strip is connected to the sliding cover plate and slides in contact with the clamping strip located below it.

[0021] Regarding the aforementioned sliding cover, it should be noted separately that this enables the connection between the cover device installed in the side area of ​​the carding machine and the outer cover of the carding machine. In this respect, it thus achieves complete coverage of one or more cylinders of the carding machine according to the invention relative to the environment, as well as complete coverage of the transition between the side area of ​​the carding machine (and the cover device disposed there) and the upper side, which is covered in its width by the sliding cover.

[0022] In an advantageous extension of the invention, the clamping bar may have an upwardly pointing guide strip, wherein a guide groove is formed in the sliding bar on the side opposite to the clamping bar, and the guide strip of the clamping bar slidably engages with the guide groove. In this way, a translational relative movement between the cover device with the clamping bar clamped on its upper edge and the sliding cover plate connected to the sliding bar can be achieved by simple means.

Detailed Implementation

[0054] Then refer to Figures 1 to 14A preferred embodiment of the carding machine for manufacturing a fiber web from fibrous materials according to the present invention is described. The same features are given the same reference numerals in the figures. It should be understood that the figures are shown in a simplified manner only, and in particular are not shown to scale.

[0055] exist Figure 1 A simplified schematic side view shows a carding machine 1 according to the invention. The carding machine 1 includes two rollers, namely a pre-carding cylinder 2a and a main cylinder 2b, respectively supported about a rotation axis A. The two cylinders 2a and 2b are respectively equipped with toothed needle cloth (not shown) in a known manner.

[0056] The carding machine 1 includes a frame 3, on which a side guard plate 4 is fixedly fastened (see reference). Figure 5 The side guard plates 4 are respectively disposed on both sides of cylinders 2a and 2b and are used for the cylinders to rotate around the corresponding rotation axis A (see reference). Figure 2 ) support.

[0057] Each of the two cylinders 2a and 2b is equipped with a cover device. Here, it is specifically divided into a first cover device V1 assigned to the pre-combed cylinder 2a and a second cover device V2 assigned to the main cylinder 2b. Both the first cover device V1 and the second cover device V2 are connected to the adjacent side guard plate 4 by fastening device B, as will be explained in detail later.

[0058] Regarding the aforementioned cover devices V1 and V2, it should be noted that the cover devices are respectively installed on the two end sides of the associated cylinders 2a and 2b, that is, they are installed along the extension of the corresponding rotation axis A from both sides.

[0059] The corresponding fastening device B is preferably made of metal, such as aluminum, stainless steel sheet, or stainless steel. This fastening device connects the first or second cover assembly V1, V2 adjacent to the end sides of the pre-combed cylinder 2a and the main cylinder 2b on the associated side guard plate. The corresponding fastening device is constructed in a flange shape such that it extends at least along an annular section about the rotation axis A of the respective cylinders 2a, 2b. This is achieved through… Figure 1 The side view shows this. Alternatively, fastening device B can also be made of plastic. Fastening device B can be cast into the side guard plate, or fastened to the side guard plate as a separate one-piece or multi-piece component.

[0060] Figure 2 Shown in another schematic, simplified side view Figure 1The pre-combing cylinder 2a and main cylinder 2b of the carding machine are now shown separately for better illustration, wherein, between and adjacent to the cylinders 2a and 2b, there are frame devices (not labeled in detail) for other machine components of the carding machine 1. It can be clearly seen that cover devices V1 and V2 are further disposed on the side guards of the cylinders and are moved apart together with the side guards. Therefore, only the cover devices are removable; the associated rollers and frame must remain within them.

[0061] A flange-shaped fastening device B is used to connect the first cover device V1 or the second cover device V2 to the side guard plate 4 of the pre-combed cylinder 2a or the main cylinder 2b. The flange-shaped fastening device is formed by multiple ring segments R, which are fastened to or cast onto the side guard plate 4. Figure 2 In the side view, these ring segments for the first cover device V1 and the second cover device V2 are exemplarily marked with "R" at some locations.

[0062] The first cover device V1 and the second cover device V2 are both composed of multiple planar segments F, which are arranged in a ring around the rotation axis A of the corresponding cylinders 2a and 2b. This is achieved by the cover devices V1 and V2 according to... Figure 3 The side view shows that, in detail, the first cover device V1 consists of planar segments F1 and F2, while the second cover device V2 consists of planar segments F4, F5 and F6.

[0063] The isometric segment F9 is located in the middle between the pre-combed cylinder 2a and the main cylinder 2b. The isometric segments F3, F7, F8 and F9 are assigned to the transfer rollers or stripping rollers. Figure 3 The separate planar sections of the cover assembly (F1 + F2; F3; F9; F4 + F5 + F6; F7; F8) are also shown, and these planar sections are assigned to the corresponding rollers and frames.

[0064] The cover devices V1 and V2 can be made of transparent plastic, such as polycarbonate (PC). This type of plastic allows for observation from the outside into the combing machine 1 due to its transparency and also stands out for its good impact toughness, thereby reducing or even eliminating the risk of the planar sections that make up the cover devices V1 and V2 breaking or cracking. Alternatively, the cover devices V1 and V2 can also be made of wood, aluminum, or another metal.

[0065] Figure 4 The side view is shown again. Figure 1 The drawing shows the pre-combing cylinder 2a and the main cylinder 2b of the carding machine, and indicates the corresponding rotation axis A, with the cylinders 2a and 2b arranged to be supported around the rotation axis. This is understood to mean that these rotation axes A extend perpendicularly to the drawing.

[0066] Figure 5 A perspective view of a segment of the side guard plate 4 is shown, on which a ring segment of the fastening device B is mounted to connect a planar segment F of the cover devices V1 and V2 to the segment. Further details are shown in the diagram. Figure 6 The cross section Figure 7 Therefore, it can be seen that the annular segment of fastening device B is fastened to the side guard plate 4 by means of a threaded connection (not shown in detail). Alternatively, fastening device B can also be cast onto the side guard plate 4. It should be emphasized that the planar segment F is fastened to fastening device B by means of countersunk screws 8. The flat head of this countersunk screw 8 is received in the through hole of the planar segment F and is flush with the outer surface of the planar segment, thereby ensuring that the end sides of adjacent machine components 7 of the combing machine 1 (such as...) are... Figure 6 (As can be seen) There is a very small gap between the planar segment F and the head of the machine element 7 and the countersunk screw 8, so that there is no contact between them.

[0067] Figure 5 It is also shown that a notch 6 is constructed on the radial outer edge region 5 of the fastening device B. This notch 6 serves the purpose that the machine element 7 or associated bearing of the carding machine 1 can extend through the notch 6 without "blocking" the fastening device B or associated ring segment R. In other words, the notch 6 allows the fastening device B or associated ring segment R to be positioned close to the end side of the machine element 7 of the carding machine 1 and fastened to the side guard plate 4 on that end side without causing, for example, collision with the bearing shaft or similar component of the machine element 7.

[0068] The aforementioned notch 6 in the radially outer edge region 5 of the fastening device B also provides the advantage that the sector adjacent to the notch 6 in the edge region 5 can extend relatively far outward from the associated side guard plate 4 in the radial direction (relative to the cylinder's rotation axis A) without interfering with the machine element 7 or its bearing element. This simplifies the threaded connection of the planar sections F of the cover devices V1 and V2 on the associated fastening device B and its annular sections.

[0069] As described above, the combing machine 1 according to the present invention includes a first cover device V1 and a second cover device V2. Referring then to... Figure 7 and Figure 8 Explain how the planar sections of the cover devices V1 and V2, which are adjacent to each other in the middle of the pre-combed cylinder 2a and the main cylinder 2b, can be connected to each other.

[0070] Figure 7 A perspective view of the planar segment F of the clamping plate 13 together with the adjacent cover devices V1 and V2 is shown, wherein, Figure 8 A cross-sectional view is shown passing through the clamp 13 and the planar segment F to be connected.

[0071] Figure 8The planar segment shown on the left belongs to the first cover device V1 and is accordingly marked "F(V1)", and this planar segment is planar segment F2 (see reference). Figure 3 ). Figure 7 The planar segment shown on the right belongs to the second cover device V2 and is accordingly marked "F(V2)". This planar segment is planar segment F5 (see reference). Figure 3 This means that the two planar sections F2 and F5 are directly adjacent when the two cover devices V1 and V2 are assembled.

[0072] To connect adjacent planar segments F2 and F5, their edge regions are appropriately overlapped. Through holes are constructed in both planar segments F2 and F5, and these through holes are secured by screws 14 (see reference). Figure 8 The screw 14 is threaded through the through hole in the planar section. For this purpose, a threaded hole is constructed in the clamping plate 13, which is aligned with the through hole in the planar section, and the free end of the screw 14 can be screwed into the threaded hole.

[0073] exist Figure 7 and Figure 8 The screw 14 is shown in the tightened state, wherein the two planar sections F2 and F5 are threaded together and connected to the clamp 13.

[0074] The through-hole in the planar section F5 can be constructed, for example, as an elongated hole 15 (see reference). Figure 8 Therefore, it is possible to adjust the two planar segments F2 and F5 relative to each other before tightening screw 14 so that length compensation between the two planar segments F2 and F5 can be achieved if necessary.

[0075] Therefore, the clamp 13 can achieve a dual function: it can not only construct adjacent planar sections for connecting the respective cover devices V1, V2, but also, based on the elongated holes constructed in the edge region in at least one of the planar sections, it can also perform a position compensation function so as to compensate for the length between the two cover devices V1, V2 when necessary.

[0076] The arrangement of the clamping plate 13 between the planar sections F2 and F5 of the adjacent cover devices V1 and V2 can also be... Figure 3 This can be seen in the side view.

[0077] As described above, both cover devices V1 and V2 are composed of multiple planar segments. (Refer to...) Figure 9 and Figure 10 Describe how the planar sections of a cover device can be connected to each other.

[0078] Figure 9A perspective view of a connecting strip 9 is shown, which is used to connect planar sections of a cover device V1, V2 to each other. For this purpose, the connecting strip 9 has slots 10 facing opposite sides. In at least one of the slots 10, at least one protrusion 12 is formed outward on the inner surface 11.

[0079] Figure 10 Show Figure 9 The connecting strip 9, wherein two planar sections of a cover device are mounted into the slot 10. Planar sections F1 and F2 of the first cover device V1 can be connected to each other, for example, by means of such a connecting strip 9, as in... Figure 10 As indicated in the diagram. Here, the planar segment F2 is securely clamped and received within the associated slot 10 due to the protrusion 12. Therefore, in view of the fact that according to Figure 10 Another slot 10, in which the planar segment F1 is mounted, has no protrusions on its inner surface 11. The planar segment F1 is simply inserted into this slot 10, wherein, considering the protrusion 12, the clamping "strength" of the edge region of the planar segment F1 within the slot 10 is lower than that of the planar segment F2. This allows the planar segment F1 to move slightly within the associated slot 10, thereby allowing, for example, tolerances or thermal expansion.

[0080] alternative to Figure 9 In another embodiment, protrusions 12 may be constructed on the aforementioned inner surfaces of the two slots 10 of the connecting strip 9. These protrusions may have different heights or sizes in the corresponding slots, so that in this case, the planar segment F may also move slightly in the associated slot.

[0081] Regarding the aforementioned connecting strip 9, it should be understood that, thereby, whether in the first cover device V1 or the second cover device V2, all remaining adjacent planar segments can also be connected to each other in the manner described. With appropriate modifications, this also applies to the connection between planar segments F2 and F4 (see...). Figure 3 The planar segment F9.

[0082] When the cover devices V1 and V2 are assembled on the carding machine 1, the cover devices have a horizontal upper edge 17 (refer to...). Figure 1 The combing machine 1 includes a sliding cover 16, which is movably guided along the upper edge 17 of the horizontal plane. For this purpose, a sliding system 18 is used, which is subsequently referred to... Figure 11 and Figure 12 Show and describe in detail.

[0083] Figure 11A cross-sectional view through a sliding system 18 is shown, which includes a clamping bar 19 and a sliding bar 20. The clamping bar 19 is fastened to the horizontal upper edge 17 of the cover devices V1, V2, i.e., fastened to the associated planar segment F. Considering... Figure 3 In the view shown, the clamping bar 19 can be fastened from above to the planar section F2 of the first cover device V1, and in the same manner to the planar sections F5 and F6 of the second cover device V2. For this purpose, a slot (not marked in detail) is used in the clamping bar 19, into which the upper edges of the planar sections F2, F5, and F6 are inserted. The clamping bar 19 has a guide strip 21 in the area opposite to the slot. The clamping bar 19 is fastened to the aforementioned planar sections such that the guide strip 21 is oriented upwards. The function of the guide strip 21 will be described separately later.

[0084] The sliding strip 20 is fastened to the lower edge of the sliding cover plate 16. A guide groove is constructed in the sliding strip 20. Figure 11 As shown, the sliding bar 20 is installed on the lower edge of the sliding cover plate 16 such that the guide groove 21 points downward here.

[0085] The clamping bar 19 can be made of metal, such as an aluminum profile. The sliding bar 20 is preferably made of a low-friction plastic material with good sliding properties. Accordingly, this ensures that the guide bar 21 moves along or within the guide groove 22 with low frictional resistance.

[0086] The aforementioned sliding system 18 operates on the following basis: When the carding machine 1 is assembled, the guide strip 21 of the clamping strip 19 and the guide groove 22 of the sliding strip 20 slide and engage with each other, similar to a labyrinth seal. Specifically, this means that the guide strip 21 engages with the guide groove 22 from below, thereby allowing the sliding strip 20 to move relative to the clamping strip 19. In this way, the sliding cover 16 can move along the horizontal upper edge 17 of the cover devices V1 and V2.

[0087] Figure 13 and Figure 14 Other side views of the combing machine 1 according to the invention are shown and it is indicated that it can be used. Figure 8 and Figure 9 Connecting strip and Figure 11 and Figure 12 The possible positions of the sliding system 18.

[0088] exist Figure 13 and Figure 14 In the side view, the boundary regions between adjacent planar segments of the first or second cover device V1, V2 are respectively shaded, with the shaded lines extending rectangularly along the edges of these boundary regions. It should be understood that these boundary regions are where [the following is applicable / can be used]. Figure 9 / 10 connecting strip 9, so as to connect the planar sections of the cover device to each other as described.

[0089] In addition, Figure 13 and Figure 14 In the side view, the boundary region located at the horizontal upper edge 17 of the cover device is correspondingly shaded by a shading line that extends obliquely along the edge of the boundary region. This means that a sliding system 18 can be provided in this boundary region, i.e., on the horizontal upper edge 17 of the first cover device V1 and the second cover device V2.

[0090] Finally, it should be noted that the guide groove 22 in the slider 20 has a chamfer 23 on one end side. This allows for... Figure 14 The view further shows a bottom view of the slider 20. These chamfers 23 on this end side of the slider 20 widen the guide groove 22 and thus facilitate the guide bar 21 into the guide groove 22.

[0091] The chamfer 23 is primarily used to facilitate the mounting of the sliding cover 16 and the sliding strip 20 fastened thereto on the horizontal upper edge 17 of the cover assembly V1, V2, and also to ensure that the movement of the sliding cover 16 along the horizontal upper edge 17 can be carried out in an operationally safe manner without causing the guide strip 21 to be misaligned or jammed with the guide groove 22 constructed in the sliding strip 20.

[0092] With the help of the present invention, the inner cover of the first or second cover device V1, V2 of the carding machine 1 is integrated or connected to the corresponding side guard plate 4 of the carding machine 1 in a space-saving manner and with simple means.
