Transmissions, drives and spinning machines

Abstract

The transmission section of the transmission mechanism (2), which has a drive shaft (7) and a driven shaft (8), includes a first transmission element (21) that is rotatably and effectively connected to the drive shaft (7) as a component of a first transmission stage, and a second transmission element (21) that is rotatably and effectively connected to the driven shaft (8) and the second transmission element (21) as a component of a second transmission stage, different from the first transmission element (17). The transmission mechanism (2) is designed such that a drive rotation of the drive shaft (7) through a first drive rotation angle in the drive rotation direction causes the driven shaft (8) to rotate through a first driven rotation angle (α) in the first driven rotation direction. Subsequently, a drive rotation through a second drive rotation angle causes the driven shaft (8) to rotate through a second driven rotation angle (β) in the second driven rotation direction opposite to the first driven rotation direction. The sum of the driven rotation angles (α, β) is less than or equal to 960° and is different from each other. The two transmission mechanisms (2) can be attached to each other so that they are technically connected to each other in terms of drive technology. The drive section of the device (1) can be rotatably and effectively connected to a transmission mechanism (2) on the driven side. The spinning machine has a pair of rollers (80) that cooperate with each other in fiber transport and a device (1) in which the driven shaft (8) of the transmission mechanism (2) is rotatably and effectively connected to one of the rollers (80) of the pair of rollers (80).

Description

Technical Field

[0001] The present invention relates to a transmission mechanism, an apparatus formed using the transmission mechanism, and a spinning machine equipped with such an apparatus. Background Technology

[0002] A known driver is used for the rollers in a rotating spinning machine (i.e., a spinning and spinning preparation machine). This driver operates by either directly driving the corresponding roller with a drive motor, or indirectly through a transmission section in the form of a wheel drive assembly or a traction drive assembly.

[0003] If interconnected rollers need to repeatedly rotate sequentially through different rotation angles in opposite directions (Pilger motion rotation), an expensive structure is required due to the drive motors to be installed, the coupling of the transmission technology, and / or the energy consumption during operation. In any case, such a structure is expensive.

[0004] Existing technology knows of Pilger motion transmissions, which are based on a first drive wheel rotating eccentrically, i.e., off-center. A second drive wheel, arranged at fixed intervals via slats, continuously meshes with the first drive wheel. This second drive wheel is oscillating and rotating, transmitting its rotation to a third drive wheel arranged on a fixed shaft. Here, the third drive wheel performs the resulting Pilger motion rotation. The disadvantages of this transmission method are that all three drive wheels are forcibly coupled to each other. Furthermore, the oscillation of two drive wheels results in a huge mechanical load and high energy consumption. In particular, this transmission method is inflexible because the construction and arrangement of each drive wheel must be coordinated with the other two. In addition, this transmission mechanism is particularly long in construction. Adjustment of the engagement point can only be achieved at a considerable cost. For this purpose, it is especially necessary to open the transmission housing and place the lubricated transmission device into the internal space of the transmission housing. Therefore, the housing must be opened for adjustment, which brings structural costs (and associated expenses) and the risk of contamination associated with opening the housing. Furthermore, the transfer function from the drive shaft to the separation roller cannot be changed to generate Pierce motion. In particular, adjustments are very time-consuming because the machine must be shut down during adjustments.

[0005] Furthermore, direct drives, such as those in the form of servo motors, are known to be used. However, these direct drives are very expensive, have high energy losses in the transmission mechanism, and are very inefficient. In addition, the very frequent reversal of rotation direction places a high load on the motor, resulting in the generation of enormous heat, which requires expensive cooling. Furthermore, the disadvantage of dividing such an active cooling system into two machine parts is that the system is coupled and filled during factory assembly for trial operation and then decoupled for transport. Summary of the Invention

[0006] The objective of this invention is to provide a low-cost, flexible, and energy-efficient transmission mechanism, a drive unit formed using such a transmission mechanism, and a spinning machine equipped with such a drive unit.

[0007] This task is addressed by the subject matter of the independent claims. Advantageous further extensions are given in the dependent claims.

[0008] The transmission mechanism according to the invention has a drive shaft, a driven shaft, and a transmission section. The transmission section includes a first transmission element, which is rotatably and effectively connected to the drive shaft as a component of a first transmission stage. Furthermore, the transmission section includes a second transmission element, different from the first transmission element, which is rotatably and effectively connected to the driven shaft as a component of a second transmission stage. The second transmission element is also rotatably and effectively connected to the first transmission element. Thus, the first and second transmission elements and the two transmission stages can be arranged separately in position. The transmission mechanism is designed such that a drive rotation of the drive shaft through a first drive rotation angle in a predetermined drive rotation direction causes the driven shaft to rotate through a first driven rotation angle in a first driven rotation direction. Subsequently, a drive rotation through a second drive rotation angle causes the driven shaft to rotate through a second driven rotation angle in a second driven rotation direction opposite to the first driven rotation direction. According to the invention, the aforementioned driven rotation angles are different from each other. That is, the driven shaft performs a Pilger motion rotation. The advantage of having transmission elements that can be arranged separately from each other is that these transmission stages do not need to be arranged in a coordinated manner and do not require coordination with each other; they can be optimized according to their respective functions in the context of generating Pilger motion, and this requires at most one more element than known transmission mechanisms. It allows for better distribution of mechanical loads or the use of energy-efficient materials. This enables adaptation to different operating conditions. Furthermore, it is surprising to find a transmission mechanism that, despite its simple structure, can still operate quite quickly, energy-efficiently, and with relatively low vibration. For example, in the case of driving the separation roller, the transmission mechanism is operable at a combing cycle count of 1500 nips / min, which makes it possible for the combing machine to operate at even faster speeds.

[0009] The sum of the driving rotation angles is preferably 960°. That is, a full rotation of the drive shaft causes a Pilger motion rotation according to the present invention. This eliminates the need for potentially necessary measures regarding the rotation angle, such as the conversion of the rotation ratio, thus keeping the structure simple.

[0010] Alternatively or additionally, the sum of the driven rotation angles is less than, equal to or greater than 960°.

[0011] The rotationally efficient connection between the first and second transmission elements is preferably formed by having a transmission shaft on which the first and second transmission elements are arranged in a torsion-resistant manner. This results in a compact and simple transmission assembly. If the device is detachable, adjustments can be made by replacing the corresponding transmission element without affecting the arrangement or function of the transmission stage to which the other transmission element belongs.

[0012] In two variations of the transmission mechanism, the transmission section may have a drive element. According to the invention, this drive element is rotatably and effectively connected to the drive shaft and includes a carrier. The carrier is spaced apart from the axis of rotation of the drive element and arranged anti-torsional relative to the drive element. Therefore, the carrier performs rotation about the rotation center of the drive element, i.e., eccentric rotation. Furthermore, the carrier forms part of a first transmission stage. This causes the carrier to rotate about itself and simultaneously about the rotation center of the drive element as the drive element rotates. This causes motion superposition, and this motion transmission causes oscillation and simultaneously causes the first transmission element to rotate. Therefore, a Pilger motion rotation of the driven shaft can be generated based on the second transmission stage. And, because the first transmission element does not directly interact with the other transmission element, no additional adjustments are required; the structure is simplified and therefore low-cost.

[0013] The driving component preferably has a third transmission element or forms a third transmission element itself. This third transmission element is rotatably and effectively connected to the first transmission element directly or through the first transmission element and is arranged at a fixed distance from the first transmission element. Therefore, the oscillation of the first transmission element is generated in a simple manner.

[0014] Alternatively or additionally, the transmission mechanism may have an adjustment device. The adjustment device is designed to change the rotational position of the drive member relative to the drive shaft. If the transmission mechanism is used to drive the separating rollers of a combing machine, this allows for adjustment of the so-called engagement timing.

[0015] In all the aforementioned transmission mechanisms, the transmission section may have a fourth transmission element, which is rotatably and effectively connected to the driven shaft. The fourth transmission element forms part of the second transmission stage and is rotatably and effectively connected to the second transmission element directly or through the second transmission element.

[0016] In the case of a corresponding direct rotational effective connection, the transmission elements of the associated transmission stage are preferably formed by means of gears, which mesh with each other in pairs (i.e., not all as a single unit). That is, two gears mesh with each other, but not with a third of the remaining gears. This is a low-cost transmission conversion.

[0017] In the case of a corresponding indirect rotary effective connection, the transmission elements of the associated transmission stage are formed by steering rollers, and annular transmission devices surround these steering rollers. This is also a transmission mechanism that can be manufactured at low cost.

[0018] The annular transmission device is preferably formed using commercially available drive belts, ropes, or chains. The associated transmission element is a steering roller, or each element has its own steering roller. This results in a conventional traction drive assembly.

[0019] Preferably, each of the aforementioned transmission mechanisms is constructed as a module. That is, the transmission mechanism can be used between the driver and the component to be driven (such as the separating roller of a combing machine). This greatly simplifies assembly.

[0020] Here, the transmission mechanism is preferably configured in the first position such that the drive shaft is effectively rotatably connected to the module from the outside. Therefore, the transmission mechanism can be equipped with or coupled to a driver in a fairly simple manner. In the simplest case, the driver is formed by means of a motor.

[0021] The last transmission mechanism mentioned can also be designed such that the rotation of the drive shaft is derived from the module at a second position different from the first position. Therefore, the effect of the drive (i.e., the transmission-drive shaft rotation) is provided to other components, such as another transmission mechanism.

[0022] Here, the first position is preferably designed to be rotatably connected to the second position. This allows for the sequential connection of multiple identical transmission mechanisms in a single chain. Therefore, each transmission mechanism can also be coupled to a driver; this increases flexibility. Costs can also be saved due to the standardized construction of such transmission modules.

[0023] Each of the aforementioned transmission mechanisms, having first and second positions, can be designed such that rotation of the driven shaft originates from the module in the third position. Therefore, the transmission mechanism can also be constructed as a module independent of the actual element to be driven. This promotes standardization and flexibility in use.

[0024] Preferably, the rotation of the drive shaft at the second position or the rotation of the driven shaft is derived by means of the free end of the corresponding shaft relative to the module. Therefore, no structurally costly solution is required.

[0025] Furthermore, the present invention proposes a system comprising two of the aforementioned transmission mechanisms. According to the invention, these two transmission mechanisms are designed to be attached to each other such that they are simultaneously connected to each other in terms of drive technology. Therefore, purely mechanical fastening of the transmission mechanisms is sufficient to establish an effective drive connection. This greatly simplifies assembly. Alternatively or additionally, the transmission mechanisms are designed to be arranged such that their drive shafts are effectively rotatably connected to each other via a single shaft. That is, a drive device is thus created that can utilize only a single drive motor, but can drive multiple transmission mechanisms or multiple elements to be driven by these transmission mechanisms.

[0026] The device according to the invention has at least one of the aforementioned transmission mechanisms. Furthermore, the device has a drive section that is rotatably and effectively connected on the driven side to an associated transmission mechanism in the at least one transmission mechanism. Therefore, the transmission mechanisms are functionally integrated.

[0027] Preferably, the device has multiple transmission mechanisms that derive the rotation of the drive shaft at a second position. These multiple transmission mechanisms are thus effectively rotatably connected to each other, such that, in addition to the associated transmission mechanism, other transmission mechanisms among the multiple transmission mechanisms are effectively rotatably connected at their first positions to the second position of the transmission mechanism located upstream along the drive direction. This generates the aforementioned drive chain, which, in extreme cases, requires only a single driving component. The identical construction of the transmission mechanisms also reduces manufacturing costs. Therefore, the entire drive system can be divided into two main machine parts (a core part and a main part in the form of two transmission mechanisms).

[0028] Here, preferably at least two of the plurality of transmission mechanisms are constructed as described in the above system and are directly or indirectly attached to each other. This creates a drive chain, which is generated solely by the mechanical coupling between the transmission mechanisms, achieved, for example, through corresponding coupling rods. Therefore, no further work is required, keeping assembly simple.

[0029] The spinning machine according to the invention has at least one pair of rollers that cooperate with each other in fiber transport and one of the aforementioned devices. Here, the driven shaft of the transmission mechanism is rotatably and effectively connected to one of the associated rollers of the at least one pair of rollers. The one roller thus forms the element to be driven relative to the transmission mechanism.

[0030] Preferably, the spinning machine is configured as a combing machine. The aforementioned rollers of the at least one pair of rollers form separation rollers. Therefore, a scalable drive system for the combing machine is produced. The number of drive mechanisms that can be driven by a single drive mechanism depends on their total energy consumption relative to the drive mechanism.

[0031] Preferably, each of the aforementioned spinning machines has multiple pairs of rollers. As mentioned earlier, the transmission mechanisms are rotatably connected to each other, i.e., forming a drive chain. Here, the driven shaft of each transmission mechanism is rotatably connected on the driven side to one roller of the associated pair or more pairs of rollers. Attached Figure Description

[0043] Figure 10 Show Figure 8 Modification of the transmission mechanism on the left side of the middle section. Detailed Implementation

[0044] Figure 1 shows the transmission mechanism 2 according to the first embodiment of the present invention, which is in three operating states within the range of its torque transmission element.

[0045] The transmission mechanism 2 includes a drive shaft 7 on which a gear 18 is arranged in a torsion-resistant manner. The gear 18 meshes with a gear 19 arranged in a torsion-resistant manner on a shaft 9. A crank 22 is arranged in a torsion-resistant manner on the same shaft 9. A drive member 23 is eccentrically fastened to the crank 22 relative to the axis of rotation of the shaft 9 or the crank 22 such that, in the example shown, the drive member 23 extends outward from the plane of the drawing in the direction of the axis of rotation of the shaft 9. Therefore, the drive member 23 is constructed as a protrusion and, in the example shown, has a circular cross-section.

[0046] Furthermore, the transmission mechanism 2 has a shaft 17, whose axis of rotation extends parallel to the axis of rotation of shaft 9 and is arranged spaced apart from the other aforementioned devices. An annular traction member 26 here surrounds the two elements 17 and 23 in the form of a transmission belt.

[0047] The drive element 23 and the shaft 17 are rotatably supported in the slat 24 via a bearing 4. Here, the slat 24 not only provides support but also ensures the spacing between the elements 17 and 23, that is, it also serves as a spacing maintainer.

[0048] A gear 21 is arranged anti-torsionly on shaft 17, and this gear meshes with gear 20. Gear 20 is arranged anti-torsionly on driven shaft 8 of transmission mechanism 2, and driven wheel 11 of transmission mechanism 2 is additionally arranged on driven shaft.

[0049] Two gears 20 and 21 are rotatably supported in slat 25 via bearings 4, each concealed in Figure 1. The function of slat 25 relative to elements 20 and 21 is the same as that of slat 24 relative to elements 17 and 23. The two slats 24 and 25 are rotatably hinged to each other, wherein the axis of rotation of the joint coincides with the axis of rotation of shaft 17.

[0050] according to Figure 1a Radial straight lines are drawn as solid lines on components 11 and 21. These lines represent the corresponding gears 11 and 21. Figure 1a The rotational position is shown in the operating state and the rotational position markings 11a or 21a are formed accordingly.

[0051] Assuming drive shaft 7 rotates counterclockwise, then Figure 1b The diagram shows the operating state of the transmission mechanism 2 after gear 19 has rotated 180° (i.e., it has turned half a turn clockwise). Due to the arrangement, crank 22 has also turned half a turn, so the drive member 23 is located on the bottom side of crank 22. Due to the anti-torsion arrangement relative to crank 22, drive member 23 has also turned half a turn clockwise.

[0052] Further assuming that the drive element 23 and the shaft 17 have the same diameter, and that the shaft 17 and the gear 21 have also rotated clockwise by half a turn, as indicated by the rotation position mark 21b.

[0053] Based on the pivoting of slats 24 and 25, the rotation of gear 21, and the transmission ratio between gears 20 and 21, gear 20 and driven wheel 11 also rotate clockwise by a rotation angle α, as indicated here by the two rotation position markings 11a and 11b on driven wheel 11.

[0054] Figure 1c The transmission mechanism 2 is shown after gear 19 has rotated another 180° (i.e., relative to...). Figure 1a The crank 22 and drive 23 have also rotated the second and a half revolutions, thus components 17 and 21 have rotated the second and a half revolutions. Therefore, components 17, 19, 21-23 have all reached the operating state (having already rotated a full clockwise revolution). Figure 1a The rotation position is shown.

[0055] Forced return based on slats 24 and 25 Figure 1a The initial pivot position, the rotation of gear 21, and the transmission ratio between gears 20 and 21, gear 20 and driven wheel 11 now rotate counterclockwise by a rotation angle β, as indicated here by the two rotational positions marked 11b and 11c on driven wheel 11.

[0056] It can be seen that the rotation angle β is significantly greater than the rotation angle α, thus obtaining the desired Pilger motion rotation of the driven wheel 11.

[0057] Figure 2 from Figure 1a The invisible back side is shown Figure 1a The transmission mechanism 2 has a second slat 25 provided for stability reasons. Of course, only one slat 25 may be provided in total.

[0058] Figure 3 Showing in cross section the location Figure 1a The transmission mechanism 2 shown in the operating state has a housing 90.

[0059] Other transmission devices besides the driven wheel 11 are housed in the internal space 99 of the transmission mechanism housing 90. The housing 90 has wall sections 40, which, in the illustrated example, support shafts 7-9. The drive wheel (gear) 18 is rotatably supported, for example, by means of corresponding bearings 4, in the two opposing, vertically extending outer walls of the wall sections 40. Thus, the shaft 7 can be accessed from the two opposing outer sides of the housing 90.

[0060] The shaft 7 has an engaging protrusion 5 at its left end, which is preferably constructed complementary to the engaging recess 6 constructed at the right end of the shaft 7. This allows multiple transmission mechanisms 2 to be attached to each other, wherein the engaging protrusion 5 of one transmission mechanism 2 rotatably engages with the engaging recess 6 of the corresponding transmission mechanism 2. This allows multiple transmission mechanisms 2 to be driven using only one drive element (motor). Furthermore, this enables the construction of standard transmission mechanisms that can be mass-produced and relatively inexpensive. It is particularly convenient for assembly, as multiple transmission mechanisms 2 will not be incorrectly assembled.

[0061] The shaft 9, which is anti-torsionly arranged with gear 19 and crank 22, is also rotatably supported at both ends by bearings 4 in the left outer wall and advantageously in the partition wall 42 in the internal space 99. If the stability is sufficient, the bearings 4 and / or partition wall 42 can be omitted.

[0062] It can be seen that the bearing 4, which allows the slat 24 to rotate freely, supports the drive element 23 and the shaft 17, as well as the traction element 26 surrounding the elements 17 and 23.

[0063] Gear 21 is arranged on shaft 17 in a way that prevents twisting. In addition, it can be seen that bearing 4 supports shafts 8 and 17, allowing slat 25 to rotate freely.

[0064] Similar to shaft 7, shaft 8 is advantageously rotatably supported in the two aforementioned vertically extending outer walls of the wall section 40 by means of corresponding bearings 4. Shaft 8 extends to the right from the housing 90. The driven wheel 11 of the transmission mechanism 2 is anti-torsional mounted on the free end of shaft 8 to the right. The driven wheel 11 is used to attach the transmission mechanism 2 to the roller to be driven, such as the separating roller 80b of the combing position of a combing machine, which will be described in detail later.

[0065] The housing 90 preferably has a protrusion 91 on the left side of the wall section 40, which has an internal recess 95 in which an engaging protrusion 5 is arranged. The protrusion 91 protects the engaging protrusion 5 from external mechanical influence.

[0066] The housing 90 has another protrusion 92 on the right side of the wall section 40 opposite to the protrusion 91. The protrusion 92 is preferably constructed to complement the inner contour of the recess 95. This allows the two housings 90 to be interlocked such that the housings 90, 90 can be assembled with each other without twisting.

[0067] The protrusion 91 preferably has threaded holes 97, which, when viewed along the axis of rotation of shafts 7-9, align with through holes 98, which are constructed in upwardly and downwardly extending protrusions 93, 93 on the protrusion 92. The protrusion 92 internally includes a recess 96, in which shaft 7 and engaging recess 6 are preferably also mechanically protected and accommodated. The protrusions 91 and recess 96 are preferably configured to be form-fitted and / or force-locked into each other, which preferably simplifies anti-torsion assembly.

[0068] Figure 4 A drive unit 1 with two transmission mechanisms 2 is shown.

[0069] The housings 90, 90 of the two transmission mechanisms 2, 2 are fixed together by pushing the protrusion 92 of the left housing 90 into the recess 95 of the protrusion 91 of the right housing 90, and by screwing the associated bolt 3 through the through hole 98 of the left housing 90 into the threaded hole 97 of the right housing 90, which is also invisible.

[0070] On the left side of the left housing 90, the motor 50 is fastened to the left housing 90 by means of a protrusion 51, which is preferably similar to the protrusion 91. Here, the invisible drive shaft of the motor 50 is preferably engaged around the engagement protrusion 5 of the left transmission mechanism 2, so that the motor 50 can rotate the shaft 7 of the left transmission mechanism 2.

[0071] The right-hand engagement recess 6 of the left-hand transmission mechanism 2 can also drive the right-hand transmission mechanism 2. Therefore, multiple transmission mechanisms 2 can be connected in series to form a complete drive unit for, for example, operating all combing positions of a combing machine.

[0072] This structure allows the entire drive unit to be mounted on, for example, the frame of a combing machine. Furthermore, this design enables the construction of a standardized transmission mechanism, which helps maintain low manufacturing costs.

[0073] Figure 5 shows a modified transmission mechanism 2 in two views, which is located in the drive unit 1 with separation rollers 80a and 80b as components of a combing machine.

[0074] Unlike the first embodiment, the housing 90 of the corresponding transmission mechanism 2 is in Figure 5a The left side of the comb has a protruding wall section 41, which is used to fasten to the frame 10 of the combing machine (not shown further) by means of bolts 3.

[0075] Casing 90 Figure 5a The middle is from the transmission mechanism 2 Figure 3The right side is shown in the diagram. Therefore, the protrusion 92 can be seen. It can also be seen that the protrusion 92 exemplarily has four through holes 98. Furthermore, a recess 96, preferably centrally located, can be seen, inside which the end of the shaft 7, which is not visible here, and the engaging recess 6 can be seen. Additionally, the driven wheel 11, which is anti-torsionly arranged on the shaft 8, can be seen.

[0076] Driven wheel 11 is exemplarily and effectively rotatably connected to drive wheel 13 of the separating roller device via transmission belt 12.

[0077] The drive wheel 13 is anti-torsionally mounted on or integrally constructed with the shaft 15. Behind this arrangement is a separation roller 80a and a first drive pinion 14, which is anti-torsionally mounted on the shaft 16. The first drive pinion 14 either meshes with the drive wheel 13 itself or with an invisible second drive pinion located behind it.

[0078] Separating rollers 80a and 80b have corresponding guide sections 83a and 83b in a known manner, the guide sections being in the form of circumferential surfaces for transporting the corresponding fiber strips F.

[0079] Figure 5b All are shown in accordance with Figure 5a A device 1 having a motor 50 and two transmission mechanisms 2, 2, wherein the transmission mechanisms 2, 2 are driven by... Figure 5a As shown on the right side of the image.

[0080] Two drive mechanisms 2, 2 are exemplarily mounted on the same frame wall 10 of the combing machine, for example by three bolts 3 each, other parts of the combing machine not further shown. Therefore, the housings 90, 90 of the two adjacent drive mechanisms 2, 2 are not fastened to each other. More precisely, a tubular connecting element 60 exists between the two housings 90, 90.

[0081] The connecting element 60 has a protrusion 61 at its right end. The protrusion 61 is preferably constructed to resemble the protrusion 91 of the corresponding housing 90. This means that the housing 90 adjacent to the right is screwed onto the protrusion 61 by means of bolts 3 through the protrusion 92.

[0082] The connecting element 60 has a protrusion 62 at its left end, which is preferably constructed to resemble the protrusion 92 of the housing 90 and thus fits into the protrusion 91 of the adjacent housing 90 and is also fastened there by means of bolts 3.

[0083] Within the internal space of the connecting element 60 lies a shaft 63, which is rotatably connected to two adjacent, invisible shafts 7, 7 of the transmission mechanisms 2, 2. Since the connecting element 60 serves a fastening function, a simple insertion between the shaft 63 and the associated shafts 7, 7 is sufficient.

[0084] Furthermore, the right-side separating roller assembly can be seen particularly on the right-side transmission mechanism 2. This assembly is effectively connected to the associated driven wheel 11 of the right-side transmission mechanism 2, which is covered by the transmission belt 12, via a drive belt 12. The drive wheel 13 of the right-side assembly is also covered by the drive belt 12. A connecting shaft 15 is located to the right of the drive wheel 13, on which an exemplary arrangement is... Figure 5a The drive pinion 14 is covered by the drive wheel 13. Alternatively, the drive wheel 13 has a thickness greater than the width of the drive belt 12, thereby... Figure 5a The visible drive pinion 14 can mesh with the drive wheel 13.

[0085] Furthermore, a lower separating roller 80b is anti-torsional placed or mounted on each of each shaft 15, 16. The fiber strip F is guided through between the corresponding upper separating roller 80a and the associated lower separating roller 80b in a known manner, thus omitting the need for explanation of the operating principles of the separating rollers 80a, 80b. Figure 5a The drive mechanism between the left-hand drive pinion 14 and the right-hand drive pinion 14 or drive wheel 15 and the lower separation roller 80b arranged thereon in an anti-torsion manner, together with the two upper separation rollers 80a, is known and therefore will not be described in detail.

[0086] Furthermore, it can be seen that the left transmission mechanism 2 also operates a combing position or a separating roller mechanism.

[0087] Figure 6a Also shown is the device 1 with two modified transmission mechanisms 2. The front transmission mechanism 2 is shown in the interior space 99 of the unmarked housing cover of the modified housing 90. The device 1 includes two consecutive separating roller devices, wherein a corresponding support section 84b is provided between two corresponding adjacent separating rollers 80b. The support section 84b is used in a known manner to support and prevent bending of the separating roller devices. For clarity, only the front and rear pairs of adjacent separating rollers 80b, 80b and adjacent support sections 84b, 84b are respectively labeled. The upper separating roller 80a is not shown.

[0088] The shaft 17 of the front transmission mechanism 2 is rotatably supported in a cover plate 46 via an invisible bearing. This cover plate is open to the front, but is actually constructed as a cover. Each traction element 26 of the two transmission mechanisms 2 is arranged around a steering roller 17a on the shaft 17 in an anti-torsion manner. The cover plate 46 itself is anti-torsion mounted on the housing section 45. Therefore, the shaft 17 can move relative to the housing 90. The drive shaft 7 can also be seen. Regarding the right-hand transmission mechanism 2 (housing 90 not shown), it can be seen that the shaft 8 is rotatably supported in the housing 90 (not shown) via an associated bearing 4.

[0089] Furthermore, it can be seen on the forward transmission mechanism 2 that the associated drive member 23 is not fastened to the crank 22, but rather to a washer 47a arranged on the outside of the housing 90. Each washer 47a is screwed to an associated washer 47b, which is only visible in the rear transmission mechanism and is arranged anti-torsionally on the associated shaft 9. Only the end of the shaft 9 in the rear transmission mechanism is shown. Obviously, this shaft extends further toward the forward transmission mechanism 2 into the housing 90 (not shown) to anti-torsionally support the associated crank 22.

[0090] Figure 6b Showing about Figure 6a A partially exploded view of the washer 47b of the transmission mechanism 2 at the rear center. The washer 47a here has four arched elongated holes 47c on its circumferential surface. The washer 47b has four threaded holes 47d, preferably through-holes, opening towards the washer 47a. The elongated holes 47c and threaded holes 47d are arranged such that the bolt 3 is screwed into the associated threaded hole 47d from the side of the washer 47a opposite to the washer 47b through its elongated hole 47c, or, as shown here, through the threaded hole and screwed onto the nut 30, thus securing the washer 47a to the washer 47b.

[0091] Only the shim 47b has an internal receiving hole 47e for anti-torsion arrangement with the shaft 9 (not shown). That is, the shim 47a protects this area from external influences of the transmission mechanism 2.

[0092] Gasket 47a has an inner cone 47i inside, and gasket 47b is embedded in the inner cone by a corresponding, invisible outer cone, so that the rotation axes of gaskets 47a and 47b coincide.

[0093] To allow the washer 47b to rotate relative to the washer 47a, a joint section is preferably constructed on the washer 47a, which is, for example, in the form of a hexagonal protrusion facing the steering roller 17a. This allows the washer 47a to be rotated using a common tool (e.g., a wrench) after the bolt 3 has been loosened.

[0094] If the transmission mechanism 2 is used to drive the separation roller 80b, then this configuration allows for adjustment of the engagement timing. Here, the adjustment of the shim 47b indirectly causes the rotational position to also be adjusted relative to the drive shaft 7.

[0095] To visualize the current engagement timing setting, a mark 47f is exemplarily provided on gasket 47a. This mark is in the form of a thin, black horizontal bar extending along the rotation axis of gasket 47a on its side edge. For example, a scale 47g exists on gasket 47b, which has two sets of line marks and a thin, black-outlined horizontal bar. Each of the two sets of line marks has five straight line marks extending along the rotation axis of gasket 47a, and the horizontal bar is located between the two sets of line marks and also extends along the rotation axis of gasket 47a. In the delivery state, i.e., when the engagement timing is at the basic setting, the mark 47f and the horizontal bar of scale 47g are preferably aligned. Therefore, by having the mark 47f "wander" into the corresponding associated set of line marks, adjustments to advance or postpone the engagement timing relative to the basic setting are visualized. For this purpose, gaskets 47a and 47b preferably have the same outer diameter. In particular, this configuration allows for easy retrieval of the basic setting.

[0096] Figure 7 With similar Figure 1a The view shows the transmission mechanism 2 according to the second embodiment of the present invention.

[0097] The difference between this transmission mechanism 2 and the first embodiment is that... Figure 1a The front slat 25 is replaced by a circular gasket 27. Partially obscured components are shown by dashed lines.

[0098] Figure 8 All are shown in accordance with Figure 7 The two transmission mechanisms 2 each have a housing 90 and are located in the separating roller device 1 of the combing machine. Figure 6a Compared to the illustrated embodiment, all torque-transmitting transmission elements are housed in their respective housings 90 and are thus protected from external mechanical and lubrication technologies. Figure 8 In the diagram, for the two housings 90, the transmission elements of the two transmission mechanisms 2 that transmit torque are mirror-symmetrical about each other along a vertical line along the plane of the diagram and in a direction perpendicular to the plane of the diagram.

[0099] The shafts 7 of the two transmission mechanisms 2, 2 are effectively connected to each other at their respective ends by means of shaft 63. In the example shown, this is achieved by having engagement recesses 64 at their ends. This causes the rotational movement of gears 18, 18 to induce a Pilger motion rotation in the same direction of the driven shafts 8, 8 of the associated transmission mechanism 2.

[0100] The corresponding transmission mechanism 2's gasket 27 is rotatably supported in the housing 90 via a labyrinth seal 29. The labyrinth seal 29 allows the gears 18-21 of the corresponding transmission mechanism 2 to be airtightly sealed relative to the crank drive assembly with the drive belt 26. Therefore, the arrangement of the crank 22, the drive belt assembly, and the slats 24 is located outside the space where the gears 18-21 of the corresponding transmission mechanism 2 are arranged. To protect the components of the corresponding drive belt assembly from external influences, cover plates 70 are respectively mounted on each wall section 40. This is achieved in the illustrated example by means of a locking protrusion 72, which is embedded in the corresponding locking recess 44 of the wall section 98. Preferably, a sealing portion 28 is provided between the cover plate 70 and the wall section 40. The cover plate 70 of the transmission mechanism 2 on the left has the aforementioned protrusion 92. The shaft 7 is constructed here as a two-piece unit. The first shaft segment 7b, which anti-torsionly receives the gear 18 and crank 22, is forcefully and / or form-fittedly embedded in the shaft segment 7a at its end opposite to the shaft 63, and is thus rotatably and effectively connected to the shaft segment. The shaft segment 7a also exemplarily has an engagement recess 6 at its end opposite to the shaft 63. Thus, the cover plate 70 can be removed to overcome the locking connection, allowing, for example, the replacement of a worn drive belt 26. If the cover plate 70 is reinstalled, the shaft segments 7a and 7b are once again rotatably engaged with each other.

[0101] As can be seen, the cover plate 70 of the transmission mechanism 2 on the right does not have such a protrusion 92. Therefore, the shaft section 7b is also missing here. That is, apart from the cover plate 70 and the shaft section 7a, the two transmission mechanisms are indistinguishable. This increases the number of identical parts that can be used to implement transmission mechanisms 2, 2.

[0102] Separating rollers 80a and 80b form guide sections 83a and 83b on their outer peripheries, through which the fiber strip F passes. Separating rollers 80a and 80b are rotatably supported in the wall sections 40 of two housings 90 via bridge shaft sections 81a or 81b. Shaft sections 82a and 82b exist between the guide sections 83a and 83b and the associated bridge shaft sections 81a and 81b.

[0103] Figure 9 Show Figure 8 The device 1 has a closed housing 90 and a motor 50 mounted on the transmission mechanism 2 on the left side.

[0104] Figure 10 Show Figure 8The modification of the transmission mechanism 2 on the left side is shown here. It can be seen that all torque transmission elements, including the crank 22 and the belt drive assembly, are housed within the housing 90, thus leaving only a single internal space 99. The cover plate 70 is constructed here by means of a plate-like component, which is mounted to the wall section 40 via bolts 3 and threaded holes 43. The threaded holes 43 are exemplarily constructed in corresponding protrusions 94 of the wall section 40. Here, the cover plate 70 is constructed such that it does not accommodate the shaft 8. Unscrewing the cover plate 70 allows access to the belt drive assembly, thereby allowing, for example, the replacement of the belt 26. An advantage of this embodiment is that the housing 90 can maintain a fairly simple construction. This solution is possible because the lubricating oil or grease used to lubricate the moving parts still cannot escape to the outside.

[0105] The cover plate 70 and the wall section 40 have protrusions 71 or 41, which are constructed such that the cover plate 70 is closed outward by the wall section 40 surrounding it.

[0106] This invention is not limited to the embodiments described above. The components of the transmission mechanism shown can be replaced or combined. This also applies to the possibilities given below.

[0107] The drive element 23 and / or shaft 17 and drive belt 26 can be configured as any type of traction drive assembly, such as a toothed belt, rope, etc. Alternatively or additionally, a traction tensioner can be provided. This traction tensioner can be implemented, for example, by guiding one of the bearings 4 in an elongated hole in slat 24, which extends along the line connecting the rotation centers of elements 17 and 23. Here, the corresponding bearing 4 is pressed away from the corresponding other bearing 4 arranged in slat 24 by a tensioning element (such as a pressure spring).

[0108] Furthermore, the preferred gear transmission groups 20 and 21 and the traction transmission groups 17, 23, and 26 can be interchanged with each other. Alternatively, the gear transmission groups 20 and 21 can also be replaced by any other transmission group used for transmitting torque, such as the traction transmission group or the friction wheel transmission group.

[0109] The use of connecting element 60 can be eliminated, thus retaining only shaft 63.

[0110] The number, shape, size, and arrangement of teeth on gears with 18-20 teeth can vary. The meshing methods can also differ from one another.

[0111] The rolling curves of gears 18-20 can be designed such that their distance from the rotation center of their respective associated shafts 7-9, 17 changes during travel. This can be achieved, for example, by using non-circular rolling curves. Alternatively or additionally, the corresponding rolling curves can be circular, wherein the center of the associated circle is located outside the rotation center of the respective gear 18-20, i.e., eccentrically arranged. The rolling curves can also be designed in a way that the transmission ratio between drive shaft 7 and transmission shaft 8 is variable. Advantageously, for example, the distance between the rolling curves of gear 19 increases first and then decreases again. In this case, the transmission ratio with gear 18 is preferably 1:1. Thus, transmission shaft 8 first accelerates, then may run at a constant speed, and finally decelerates.

[0112] The number, shape, size, and arrangement of the teeth of gears 18-21 can be varied. A pause can also be provided between transitions where the driven shaft 8 rotates in opposite directions. Depending on the design of transmission mechanism 2, the sum of the two rotation angles α and β can be less than 960°. The ratio of these two rotation angles α and β can also be designed differently.

[0113] Alternatively or additionally, for drive shaft 6, any other shaft 7, 16 can be designed to be rotatably connected to the corresponding shaft 7, 16 of another transmission mechanism 2. In this case, certain components can be omitted in some transmission mechanisms.

[0114] In particular, gear 19 and crank 22 can be constructed as a single unit, such that drive element 23 is directly constructed on or mounted on gear 19. The right end of shaft 9 allows elements 4, 24, and 26 mounted on drive element 23 to pass freely, at least by means of its right end.

[0115] If the multiple transmission mechanisms 2 do not need to be coupled to each other, then shaft 7 and gears 18 and 19 can be eliminated. Then, shaft 9 becomes the drive shaft of transmission mechanism 2.

[0116] Each spinning machine using the Pilger motion mechanism can be equipped with a transmission mechanism 2 according to the present invention or a device 1 formed therefrom.

[0117] Such a machine can also have multiple devices 1. Therefore, the entire drive module can be manufactured at low cost, requiring only assembly.

[0118] The separating roller devices 80b and 84b do not need to be constructed as a continuous series. They can, for example, be separated in the middle, so that the two transmission mechanisms 2, 2 are effectively connected to each other only by shaft 63.

[0119] Using this invention, for example, a Pilger motion rotation with a pre-feed rotation angle of 926.5° and a post-feed rotation angle of 204.7° can be achieved on the separating roller 80b, thereby obtaining an effective feed rotation angle of 121.8° for the separating roller 80b.

[0120] To influence the transfer function between drive shaft 7 and driven shaft 8, a large number of variable parameters are provided in the proposed drive scheme:

[0121] Number of teeth;

[0122] Geometric dimensions;

[0123] Arrangement of the crank drive assembly;

[0124] Addition height correction in spur gears, non-circular gears, and especially elliptical gears; increased drive speed on shaft 7.

[0125] Alternatively, it is conceivable that some of these parameters are designed to be adjustable, allowing the user to influence the transfer function and the amount of transport (e.g., the length of slat 24). Slat 24 could, for example, be constructed to be stretchable and thus its length could be changed by the user.

[0126] If used in a combing machine, the engagement time point can be changed during operation, for example, by using a motor-driven adjustment instead of the threaded flange adjustment shown. Alternatively, a driver acting directly on shaft 7 can be provided. This driver performs a uniform drive motion at the exact same rotational speed as motor 50. The engagement time point can be changed simply by adjusting the phase difference between this driver and motor 50. The non-uniform rotational speed of this driver can affect the transfer function.

[0127] Each transmission mechanism 2 can also be part of a larger transmission mechanism that drives other components. Such driving transmission mechanisms can also be additionally provided in the combing machine, for example, for driving one or more combing positions with an upper clamp plate.

[0128] Figure 6bThe adjustment mechanism shown can also be designed differently. The number of threaded holes 47d and elongated holes 47c can be varied. Alternatively or additionally, it is conceivable that shims 47a and 47b are rotatably attached to each other. Shim 47b has a protrusion instead of, for example, threaded hole 47d, which protrudes through the associated elongated hole 47c toward the slat 24 of shim 47a. Shim 47a also has a protrusion in a certain area (preferably at one end) that protrudes toward the slat 24 from shim 47a. In one of the protrusions, the adjusting bolt is fixedly positioned and rotatably arranged about an axis transverse to the protrusion direction of the protrusion. The other protrusion has internal threads into which the adjusting bolt is screwed. At least one of the two protrusions is rotatably arranged parallel to the axis of rotation of shims 47a and 47b. Thus, the relative position of shims 47a and 47b about their common axis of rotation can be adjusted by rotating the adjusting bolt. A lock nut can be provided to secure the final adjusted position. Alternatively, there can be an arrangement of at least one threaded hole 47d, an elongated hole 47c, and bolt 3. This arrangement simplifies the adjustment of shims 47a and 47b relative to each other. In the last case, bolt 3 must be loosened. Adjustment is achieved by rotating the adjusting bolt. In the final step, only the loosened bolt 3 needs to be tightened again. Marking 47f and scale 47g can be constructed on the corresponding additional shims 47a or 47b. This also applies to the construction of hole 47d and elongated hole 47c.

[0129] As a result, the present invention provides a simple and energy-efficient possibility for achieving Pilger motion by means of the rotation of drive shaft 7 in the same rotational direction, or more precisely, it has a simple and low-cost structure.
