Description

Technical Field

[0001] This invention relates to a textile machinery element for use in textile machinery, and a method for manufacturing the textile machinery element. For the purposes of this patent application, the textile machinery element can be various components used in textile machinery. Textile machinery elements are particularly textile tools (e.g., knitting needles, warp knitting needles, sinkers, needle selectors, quilling needles, sewing needles). Tufting needle, tufting tool, reed These are either heddles (or weblitzens) or components used to guide textile tools in textile machinery (e.g., needle bed plates on flat knitting machines, guide rods on warp knitting machines, or cylinder ribs on circular knitting machines). These textile machinery components are typically flat parts with relatively thin thicknesses. Due to their small thickness, the precision manufacturing of especially large textile machinery components is difficult. Background Technology

[0002] Therefore, as is known, for example from DE202020100948U1, large textile machinery components are composed of multiple smaller parts with coupling portions, in order to enable the manufacture of textile machinery components with particularly high precision. For the purposes of this patent application, the coupling portions are also referred to hereinafter as connecting elements, as they are used to connect multiple parts. However, connecting elements known from the prior art have shown that they cannot withstand all the loads that occur in textile machinery, and loosening of the connecting elements may occur, especially under alternating loads and bending loads. Summary of the Invention

[0003] Therefore, the objective of this invention is to provide a textile machinery element composed of multiple components that can withstand particularly large bending loads and / or alternating loads and is easy to manufacture with precision.

[0004] This task is accomplished by adding the characteristic portion to the preamble of claims 1 and 13. The textile machinery element according to the invention, suitable for use in textile machinery, comprises at least one first component with a male connecting element extending primarily in the longitudinal direction, and at least one second component with a female connecting element. However, the teachings of the invention are not limited to textile machinery elements having two components. Textile machinery elements comprising three or more components are also conceivable. According to the invention, the male connecting element has an outer contour in an xy plane opened by the longitudinal direction and a height direction perpendicular to the longitudinal direction, which is verpressed into the inner contour of the female connecting element, such that the first and second components are connected to each other. For the purposes of this patent application, the male connecting element preferably protrudes outward to form the aforementioned outer contour, while the female connecting element preferably has a notch to form the aforementioned inner contour. The connection is preferably rigid and / or non-destructively detachable. This is particularly advantageous in connections that are not fully accommodated and guided in the needle grooves or recesses of the textile machinery during operation, and therefore must be firmly and reliably maintained. For the purposes of this patent application, when such a large force must be applied to disassemble the connection to cause plastic deformation of the textile machinery element, the connection is no longer destructively removable. Since textile machinery elements are typically precision parts of precision machinery, even small plastic deformation can render them unusable. To enable the textile machinery element to withstand particularly large bending loads and / or alternating loads, while simultaneously facilitating precise manufacturing, the male and female connecting elements are in contact with each other in at least two spaced-apart pressing regions, wherein the pressing regions extend continuously in a width direction perpendicular to both the longitudinal and height directions for at least 50%, preferably at least 75%, of the width of the textile machinery element. Therefore, the pressing regions are continuous. In a pressing region, the male and female connecting elements are in continuous or uninterrupted contact with each other over a width specified earlier in the textile machinery element. Stress is generated in the textile machinery element through pressing, and this stress is greater in the pressing region than in the rest of the textile machinery element. The stress in the pressing region is particularly greater than the stress in the regions between the pressing regions. Due to these stresses, a pressing force acts on the male and female connecting elements in the pressing region. The pressing region can advantageously be created such that the outer contour of the male connecting element, in its unpressed state (i.e., before pressing), at least regionally overlaps with the inner contour of the female connecting element. Therefore, the outer contour of the male connecting element is at least regionally larger than the inner contour of the female connecting element in its unpressed state. Thus, the male and female connecting elements can have different contours and are not perfectly matched. Only through pressing do the outer and inner contours match in the pressing region. A single pair consisting of a male connecting element and a female connecting element comprises at least two pressing regions. Therefore, a textile machinery element having a first and a second component interconnected by a plurality of male and female connecting elements (where each pair has only one continuous pressing area) is not an embodiment of the teachings of the present invention.

[0005] Further advantages arise if at least one gap is arranged between at least two mutually spaced pressing regions, through which the male and female connecting elements are spaced apart. This means that a distance exists between the male and female connecting elements in the extended region of at least one gap. However, outside the extended region of the gap, particularly in the pressing region, the male and female connecting elements can be in direct contact with each other. The gap advantageously extends over at least 25%, preferably at least 50%, of the width of the textile machinery element. In a particularly advantageous embodiment, the gap extends continuously over the entire thickness of the textile machinery element. The gap is here an elongated opening. This gap can be formed such that, in the extended region of the gap, the outer contour of the male connecting element is smaller than the inner contour of the female connecting element. Therefore, the male and female connecting elements have a clearance fit in the extended region of the gap. However, the gap can also be formed by the expansion of the female connecting element during pressing. The stress generated in the portions of the male and female connecting elements adjacent to the gap is less than the stress in the pressing region. Therefore, excessive internal stress in the textile machinery element can be prevented. Simultaneously, the pressed area can be designed in this way to withstand greater stress, resulting in higher resistance of the textile machinery element to bending and alternating loads. The gap is preferably so large that it is visible to the naked eye when observing the side surface of the textile machinery element against backlighting. This means that light can be seen passing through the gap. Advantageously, however, the gap can also be subsequently filled or closed with a filler material. This means that the gap is subsequently filled after its formation. The filler material can be, for example, plastic, ceramic, or metal.

[0006] Advantageously, the male connecting element comprises a head, a shank, and a root. Preferably, the head is the end of the male connecting element pointing in the longitudinal direction x. The shank is attached to the head, and its height in the height direction is less than the height of the head at its maximum height. The root is attached to the shank in the longitudinal direction away from the head. The root connects the male connecting element to the remainder of the first component, and the root has a greater height in the height direction than the shank. Due to the smaller height of the shank, the male connecting element has two relief grooves at the transition between the shank and the head, which advantageously form a pressing area.

[0007] Advantageously, the male and female connecting elements have at least three pressing regions, each spaced apart from the other by at least one gap. For this purpose, the textile machinery element preferably includes at least two gaps. The three pressing regions are advantageously arranged symmetrically, with the axis of symmetry passing through the middle of the male and female connecting elements in the longitudinal direction, and at least one of the pressing regions located on the axis of symmetry. This creates a particularly advantageous stress state, resulting in increased resistance of the textile machinery element to bending and alternating loads. Particularly advantageously, at least one of the three pressing regions is located at the head of the male connecting element.

[0008] A further advantage arises when at least two pressing regions are subjected to pressing forces acting in opposite directions. This means that at least two different pressing forces acting on the same connecting element act in opposite directions, i.e., they have directional components acting in opposite directions. For those skilled in the art, pressing force refers to the force acting in a direction perpendicular to the contact surface between the male and female connecting elements due to the stress state generated by pressing the connecting elements. Therefore, they describe a force vector acting perpendicular to the contact surface. All pressing forces acting on the male and female connecting elements are in equilibrium with each other in the idle state of the textile machinery element. Therefore, the sum of all force vectors is zero. Tension of the textile machinery element is achieved between the pressing regions through the pressing forces acting in opposite directions. This improves the connection between the first and second components, enabling the textile machinery element to withstand greater bending and alternating loads without failure.

[0009] In an advantageous embodiment, the female connecting element includes at least two legs that enclose the male connecting element. The at least two legs thus improve the connection between the male and female connecting elements. Consequently, the textile machinery element can withstand greater bending and alternating loads. The legs are preferably arranged such that they form at least a portion of the inner contour of the female connecting element. Particularly advantageously, the legs are pre-tensioned to enclose the male connecting element, thereby applying a continuous tension force to the male connecting element. Through this measure, the textile machinery element can also withstand greater bending and alternating loads.

[0010] A further advantage arises when at least two legs each include at least one pressing region, wherein the pressing force of the pressing region has directional components that act in opposite directions to each other in a height direction perpendicular to the longitudinal direction, and the at least two legs are tensioned towards the center of the male connecting element in the height direction. The legs form a lever through which the pressing force is introduced into the textile machinery element. Due to the lever action, a better connection can be achieved between the male and female connecting elements. The pressing regions are preferably arranged at the ends of the legs so that the textile machinery element can withstand the largest possible bending and alternating loads. The pressing forces acting in opposite directions in the height direction can advantageously be provided by the male connecting element including at least two first wedge elements, each having at least one surface inclined towards the center of the male connecting element, and the legs of the female connecting element each having at least one second wedge element inclined away from the center of the female connecting element and arranged such that they respectively contact one of the first wedge elements of the male connecting element to form a pressing region at the end of each leg.

[0011] The pressing force in the pressing area of ​​at least two legs can also advantageously have a directional component in the longitudinal direction. Thus, the textile machinery components are additionally tensioned in the longitudinal direction, thereby enabling them to withstand greater bending and alternating loads.

[0012] Textile machinery components are bounded by two side surfaces in the width direction perpendicular to the longitudinal and height directions. Advantageously, the edges formed by the male and / or female connecting elements with the two side surfaces are at least partially rounded and / or chamfered, such that the rounding and / or chamfering of the edges forms at least one recess in at least one of the side surfaces. Chamfering on workpieces such as textile machinery components is generally known to those skilled in the art, i.e., a narrow face formed by chamfering instead of an edge. By rounding or chamfering, the assembly force required to press the male connecting element into the female connecting element is reduced. Thus, excessive loads or damage to the edges or side surfaces during pressing can be avoided. Such damage would result in increased notch stress in the finished textile machinery component. Therefore, by avoiding damage during assembly, the textile machinery component can withstand greater bending and alternating loads in subsequent operation.

[0013] Further advantages arise when the rounding and / or chamfering of the male connecting element to the edge of the first side surface is larger than that of the female connecting element to the edge of the first side surface, and when the rounding and / or chamfering of the male connecting element to the edge of the second side surface is smaller than that of the female connecting element to the edge of the second side surface. The first and second components can be manufactured particularly easily when the edges of the male or female connecting element adjacent to the two side surfaces of the component have different roundings or chamfers of different sizes. In finished textile machinery components, it is advantageous to arrange roundings or chamfers of different sizes relative to each other in this manner, because on each side surface, larger roundings or chamfers are combined with smaller roundings or chamfers. This achieves a particularly uniform stress distribution in the textile machinery component, enabling it to withstand particularly large bending and alternating loads.

[0014] Advantageously, the male and / or female connecting elements are shaped such that they form at least one protrusion extending into at least one recess in at least one of the two side surfaces. This protrusion additionally prevents the connection between the male and female connecting elements from loosening in the width direction. This fixation is preferably achieved through a form fit. Therefore, the textile machinery element can withstand greater bending and alternating loads. Furthermore, the protrusion at least partially closes the recess in the side surface, thereby reducing the entry of dirt into the recess. Thus, textile machinery elements can be used to produce textiles of better quality. Particularly advantageously, the protrusion at least sectionally increases one of the pressing areas, allowing for better tension between the female and male connecting elements. Therefore, the textile machinery element can withstand greater bending and alternating loads. However, the protrusions themselves are small enough that they do not form a contact between the male and female connecting elements extending over at least 50% of the width of the textile machinery element. Therefore, the protrusions alone do not create the pressing area in the sense of this patent application.

[0015] Further advantages arise when the outer contour of the male connector is 0.001 mm to 0.1 mm, preferably 0.005 mm to 0.1 mm, larger than the inner contour of the female connector in at least one of the at least two pressing regions. In this way, a very favorable stress distribution can be achieved in the textile machinery element. On the one hand, sufficiently large pressing force can be generated. On the other hand, excessive surface pressure in the pressing regions can be avoided. Therefore, such a textile machinery element can withstand very large bending loads and alternating loads while having a long service life.

[0016] The object of the invention is also achieved by a method for manufacturing textile machinery components. In this method, a male connecting element is pressed into the inner contour of a female connecting element along its outer contour. At least two mutually spaced pressing regions are formed by pressing, in which the male and female connecting elements contact each other. The pressing regions extend continuously in the width direction over at least 50%, preferably at least 75%, of the width of the textile machinery component. This produces a textile machinery component with a particularly advantageous internal stress state. In the mutually spaced pressing regions, the pressing force tensions the male and female connecting elements together, enabling the textile machinery component to withstand very large bending and alternating loads during operation. An even more advantageous stress state can be achieved if at least three, four, five, or more mutually spaced pressing regions are formed by pressing. All the above-described features of the textile machinery component according to the invention can be advantageously combined with the method for manufacturing the textile machinery component.

[0017] Advantageously, the first and second components of the textile machinery element are manufactured as separate parts, i.e., as individual parts. The textile machinery element is then obtained by joining the first and second components together. As previously described, joining is achieved by pressing the outer contour of the male connecting element of the first component into the inner contour of the female connecting element of the second component. The first and / or second components can advantageously be manufactured from flat blanks (e.g., sheets). The first and second components can advantageously be manufactured from metallic materials, but can also be manufactured from ceramic, plastic, wood, mineral materials, or any other material suitable for textile machinery elements.

[0018] Further advantages arise from measuring and preferably recording the assembly forces used to press the male and female connecting elements. The measured assembly forces are indicators of the load-bearing capacity of textile machinery components under bending and alternating loads. Therefore, by measuring and recording the assembly forces, the load-bearing capacity of the manufactured textile machinery components can be predicted and monitored. Thus, this manufacturing method ensures that the manufactured textile machinery components indeed achieve the maximum load-bearing capacity required under bending and alternating stresses.

[0030] Figure 1 A textile machinery element 1, composed of a first component 2 and a second component 3, is shown. For this purpose, the first component 2 includes a male connecting element 4, whose outer contour is pressed into the inner contour of a female connecting element 5, such that the first component 2 and the second component 3 are interconnected. Therefore, the textile machinery element 1 can be composed of multiple individual parts (or components). This has the advantage that smaller individual parts are easier and more precise to manufacture than larger, single-piece textile machinery elements 1. The textile machinery element 1 shown is implemented as a needle selector and also includes a control edge 20, a drive leg 21, an elastic element 22, and a coupling section 23 for connecting other textile machinery elements 1. However, it will be apparent to those skilled in the art that the teachings of the present invention apply not only to needle selectors but also to all other textile machinery elements that can be composed of multiple components. Furthermore, the male and female connecting elements 4 and 5 can be arranged in different locations on the textile machinery element 1 in different embodiments. For example, they can be arranged in the bar near the hook of a knitting needle to connect the working part of the knitting needle with the hook to the bar of the knitting needle. Similarly, the male and female connecting elements 4 and 5 can also be arranged in the extension area of ​​the drive leg 21 to connect the drive leg 21 to the remaining components of the textile machinery element 1. Therefore, Figure 1 The textile machinery component 1 shown is only one of many possible embodiments.

[0031] Figure 2 and Figure 3 The enlarged view shows the male connecting element 4 of the first component 2 and the female connecting element 5 of the second component 3. Figure 1 The textile machinery component 1 shown is composed of these components. Therefore, Figure 2 and Figure 3The first component 2 and the second component 3 have not yet been as described Figure 1 They are interconnected as shown. Figure 2 The male connecting element 4 includes a head 11, a rod 12, and a root 13. The head 11 forms the end of the male connecting element 4 pointing in the longitudinal direction x. The rod 12 is connected to the head 11, and its height in the height direction y is less than the height of the head 11 at its maximum height. The root 13 is connected to the rod 12 in a direction away from the head 11. The root 13 connects the male connecting element 4 to the remainder of the first component 2 and has a greater height in the height direction y than the rod 12. Due to the smaller height of the rod 12, the male connecting element 4 has two relief grooves 14 at the transition between the rod 12 and the head 11. Figure 1 In the textile machinery element 1, the relief groove 14 is particularly advantageously used to form a predefined pressing area 6 when pressing the first component 2 and the second component 3. The root 13 of the male connecting element 4 includes two first wedge-shaped elements 15, each having a surface inclined toward the middle of the male connecting element 4.

[0032] Figure 3 The enlarged view shows the female connecting element 5 of the second component 3. The female connecting element 5 includes two legs 9 extending in the longitudinal direction x. Each leg 9 has a relief groove 14, which is adapted to accommodate... Figure 2 The head 11 of the male connecting element 4. The rest of the leg 9 is shaped to grip the rod 12 of the male connecting element 4. At their respective ends in the longitudinal direction x away from the rest of the second component 3, the leg 9 has a second wedge element 16, which is inclined away from the middle of the female connecting element 5 and arranged such that it contacts one of the first wedge elements 15 of the male connecting element 4 in the textile machinery element 1, so as to form a pressing area 6 at the end of the leg 9.

[0033] Figure 4 It shows Figure 1 An enlarged view of the textile machinery element 1 within the regions of the male connecting element 4 and the female connecting element 5. The textile machinery element 1 has five pressing regions 6. Before pressing, the outer contour of the male connecting element 4 is larger than the inner contour of the female connecting element 5 in these pressing regions, such that a pressing force 8 is generated in these regions through pressing and the resulting contour matching of the male and female connecting elements 4 and 5. Figure 4 In the diagram, the pressing force 8 acting on the female connecting element 5 is represented by an arrow. According to Newton's third law, there naturally exists a reaction force equal in magnitude to the pressing force 8 acting on the male connecting element 4. These reaction forces are also pressing forces in the sense of this patent application, but in order to... Figure 4For clarity, it is not shown. In the illustrated embodiment, five pressing regions 8 are spaced apart by four gaps 7, wherein the pressing regions 8 and gaps 7 are arranged alternately along the dividing edge between the male connecting element 4 and the female connecting element 5, such that each of the gaps 7 is always arranged between two pressing regions 8 to space them apart. In the region of the gap 7, the first component 2 and the second component 3 do not contact each other. Therefore, no pressing force is applied in the region of the gap 7. Thus, a favorable stress state can be generated on the textile machinery element 1. One of the pressing regions 8 is located at the head 11 of the male connecting element 4 on the central axis 17 passing through the middle of the male connecting element 4 in the longitudinal direction x. The remaining four pressing regions 8 are symmetrically distributed about the central axis 17. Thus, a particularly favorable symmetrical stress state is formed. Furthermore, each of the pressing regions 8 is arranged at the end of the leg 9. Combined with the pressing region 8 arranged on the head 11 on the central axis 17, tensioning of the male connecting element and the female connecting elements 4, 5 is achieved over a greater length in the longitudinal direction x. The connection between the male connecting element and the female connecting element 4, 5 is therefore particularly stable.

[0034] Figure 5 An enlarged view of the area of ​​the male connecting element 4 and the female connecting element 5 in an alternative embodiment of textile machinery component 1 is shown. This embodiment is similar to... Figure 4 The difference in the embodiment shown is that the pressing area 8 on the central axis 17 of the head 11 of the male connecting element 4 is omitted. Figure 4 The gap 7 adjacent to the suppression area 8 is in Figure 5 In this embodiment, they are interconnected to form a large gap 7, which extends along the entire height of the head 11 in the height direction y. Therefore, Figure 5 The illustrated embodiments have one less pressing area 8 and one less gap 7. Therefore, the textile machinery element 1 can be manufactured more easily. In particular, the pressing of the first component 2 and the second component 3 is thus facilitated. Nevertheless, compared to textile machinery elements known in the prior art, the textile machinery element 1 in this embodiment can still withstand greater bending and alternating loads.

[0035] Figure 6 It shows crossing Figure 1The textile machinery component 1 has an AA-section, wherein a recess 19 is provided in the side surfaces 10, 110, and 210. The recess 19 is formed by rounding 18 of the edges of the male and female connecting elements 4 and 5 with the side surfaces 10, 110, and 210. By rounding 18, damage to the side surfaces 10, 110, and 210 is avoided when pressing the male and female connecting elements 4 and 5. Therefore, the textile machinery component 1 can withstand a greater load. In the illustrated embodiment, the rounding 18 of the edge of the male connecting element 4 with the first side surface 110 of the two side surfaces 10 is larger than the rounding of the edge of the female connecting element 5 with the first side surface 110. At the edge of the second side surface 210, the situation is exactly the opposite: the rounding of the edge of the male connecting element 4 with the second side surface 210 is smaller than the rounding of the edge of the female connecting element 5 with the second side surface 210. Therefore, the smaller rounding 18 and the larger rounding 18 always together form the recess 19. In this way, the male and female connecting elements 4 and 5 are in direct contact with each other in the pressing region 6, which is located in the middle of the textile machinery element 1 in the width direction z. In the illustrated embodiment, the width of the pressing region 6 in the width direction z—the pressing region width 24—is approximately 50% of the width of the textile machinery element 1 in the width direction z—the textile machinery element width 26. This creates a very favorable stress state, allowing the textile machinery element 1 to have the greatest possible load-bearing capacity during operation.

[0036] Figure 7 It shows crossing Figure 1 The BB section of textile machinery component 1 is shown. The BB section passes through the rod portion 12 of the male connecting element 4 and the leg 9 of the female connecting element 5. In the BB section shown, it can be clearly seen that the leg 9 is spaced apart from the rod portion 12 of the male connecting element 4 by gaps 7.

[0037] Figure 8 An alternative embodiment for textile machinery component 1 is shown. Figure 6 The same AA section. Because... Figure 1 The views shown are not different for the embodiment of the textile machinery component 1, therefore Figure 1 The illustrations shown also apply to this alternative implementation. Figure 6 The implementation shown is the opposite, in Figure 7In the illustrated embodiment, in the region of the protrusion 19, the male or female connecting elements 4 and 5 are respectively shaped such that a protrusion 25 is formed, which extends into the corresponding recess 19. Therefore, a form fit acting in the width direction z is formed between the male and female connecting elements 4 and 5. Furthermore, the protrusion 25 increases the contact area of ​​the pressing region 6. Therefore, the connection between the male and female connecting elements is improved by utilizing the protrusion. Thus, the textile machinery component 1 can withstand greater bending and alternating loads during operation.

[0038] Figure 9 The same was shown in Figure 8 The image shows a cross-section BB of an alternative embodiment of the textile machinery element 1. In this embodiment, it can also be seen in the BB cross-section that the legs 9 of the female connecting element 5 are spaced apart from the rod portion 12 of the male connecting element 4 by gaps 7. Only in the region of the recess 19 is the gap 7 partially closed by protrusions 25 extending into the recess 19. Therefore, dirt accumulation in the gap 7 can be prevented. Simultaneously, the connection between the male connecting element and the female connecting elements 4 and 5 is improved. Therefore, the textile machinery element 1 can withstand greater bending and alternating loads. However, the contact area of ​​the protrusions 25 is so small that they individually do not form the pressing area 6 in the sense of this patent application.

[0039] Figure 10 A schematic, non-scale illustration of a textile machinery element 1 according to the present invention is shown, which is constructed as a needle groove plate (Nadelsteg) 27 for a knitting machine. The needle groove plate 27 is composed of a first component 2 with a male connecting element 4 and a second component 3 with a female connecting element 5. Due to the male connecting element and the female connecting elements 4 and 5 of the needle groove plate 27... Figure 1 The male and female connecting elements of the textile tool 1 shown differ only in size, therefore Figures 2 to 9 The schematic (non-scale) illustration also applies to the pin groove plate 27.

The sinker 28 is composed of a first part 2 with a male connecting element 4 and a second part 3 with a female connecting element 5. Because the male connecting element and the female connecting elements 4 and 5 of the sinker 28 are connected to... Figure 1 The male and female connecting elements of the textile tool 1 shown differ only in size, therefore Figures 2 to 9 The schematic diagram also applies to settling plate 28.
