Description

Technical Field

[0001] This invention relates to a sliver can shifting device, a sliver can changer equipped with the sliver can shifting device, and a spinning machine. Background Technology

[0002] In the case of a sliver changer, particularly as a component of a spinning machine, a sliver pusher is used to remove a full sliver can from the filling position and advantageously move an empty sliver can relative to the sliver changer to the filling position. At the filling position, the sliver changer stacks the fiber sliver in the can located there in a known manner until the can is full.

[0003] Several mechanisms are known for moving the sliver can. One exists as a rotating sliver can changer, where the sliver can moves along a semicircle. In this case, multiple sliver can pushers extend independently. The independence of the sliver can pushers results in limitations on the dimensions of the filled sliver can, in particular. Furthermore, the need for multiple sliver can pushers complicates the structure.

[0004] There is also a can changer that moves the can along a straight movement path. For this purpose, there are also multiple can pushers, each of which moves an associated can.

[0005] In order to enable large-scale bar movement, the bar pushing components are driven at both ends, which complicates the structure.

[0006] Alternatively, two cane shifters can be provided for each cane, acting on both sides of the corresponding cane and causing it to move. During the return movement, these cane shifters open as they pass the next cane and close again once the last cane has been passed. Multiple cane shifters are required here, leading to a more complex structure.

[0007] What all these drives have in common is that they are either very complex in structure and therefore expensive, or they are so large that they unnecessarily increase the external dimensions of the corresponding spinning machine. Summary of the Invention

[0008] The objective of this invention is to address the aforementioned drawbacks.

[0009] According to the present invention, a skein moving device with a skein moving member is proposed. The skein moving member is guided along a predetermined movement path via one end. The driving mechanism of the skein moving device includes a driving section kinetically connected to said one end of the skein moving member. This is done according to the invention by engaging the driving section with a first transmission member, which is kinetically connected to another transmission member via a speed-changing transmission mechanism. The other transmission member engages with said one end of the skein moving member or a follower connected thereto. The driving mechanism is designed to move the driving section such that the skein moving member moves along the movement path via said one end. The speed-changing transmission mechanism is further designed such that the extension of the driving mechanism along the movement path via the speed-changing transmission mechanism is less than or equal to twice the possible maximum skein diameter of the skein moving device. This allows the entire drive of the moving skein to be limited to the size occupied by two skeins arranged side by side (with a small gap of, for example, a few millimeters or centimeters between them).

[0010] Here, the drive components and transmission mechanism preferably extend along a predetermined travel path. This allows for the use of relatively long drive components, such as pneumatic cylinders, and avoids the need for costly and expensive power steering systems.

[0011] In the case of two devices, the drive mechanism is preferably designed to reciprocate the drive section between the two end positions. This simplifies the structural construction and reduces the number of necessary components compared to a circumferentially arranged bar pusher.

[0012] Alternatively or additionally, the movement path extends in a straight line. This allows the drum to move with low friction and energy efficiency.

[0013] Alternatively or additionally, the drive mechanism is formed using a pneumatic cylinder. Correspondingly, the drive section is formed using the free end of the piston rod of the pneumatic cylinder. Pneumatic cylinders are very inexpensive. Based on the transmission mechanism, its length does not need to be equal to the diameter of the drum, but can be smaller. Thus, the pneumatic cylinder (including its maximum piston rod extension distance) can be constructed without exceeding the dimensions described above. Conversely, it is not even necessary to fully utilize these dimensions.

[0014] In all the aforementioned devices, the kinematic connection is preferably formed in such a manner that the drive section engages with the first traction member, which surrounds a first steering section around a first steering wheel and a second steering wheel. The end of the canister pusher engages with the second traction member, which surrounds a second steering section around a third steering wheel and a second steering wheel. According to the invention, the steering sections are constructed and torsionalally anti-each other such that the first steering section has a lower circumferential speed than the second steering section when the second steering wheel rotates. This causes the second traction member to move along a second path length greater than the first path length, along with the resulting movement of the first traction member along a first path length, when the first steering section rotates at a predetermined angle. This increase in path length allows the aforementioned dimensions to be maintained.

[0015] Here, the two steering sections are preferably arranged torsionally on a common shaft. According to the invention, the first steering section has a smaller diameter than the second steering section. This is a feasible solution that is structurally very simple and low-cost, achieving a difference in circumferential speed. Alternatively, the two steering sections are constructed integrally with each other. This simplifies the structural construction in such a way that, in an extreme case, the two steering sections together form the second steering wheel.

[0016] Each of the aforementioned devices may have a guide section extending along the movement path. The skein pusher has a mating guide section that engages with the guide section in such a way that the mating guide section can move along the movement path. This mechanically reduces the load on the drive mechanism that is required to guide the skein pusher. This allows for optimization of the drive of the movement path and the generation of force for moving the skein.

[0017] Alternatively or additionally, the skein pusher includes a first support section. This support section is designed such that the remaining portions of the skein pusher are distanced from at least one associated first mating element at one end along the travel path. This allows the skein pusher to operate with low friction along its travel path.

[0018] Preferably, the first support section is formed by means of a mating guide section. Therefore, the section achieves a dual function, helping to maintain a low number of parts and / or a low size of the guide section for the bar pusher.

[0019] Each of the aforementioned skein pushers may have a second support section at its other end. The second support section is designed to keep the other portions of the skein pusher at one other end distanced from at least one associated second mating element. This also serves for low-friction operation of the skein pusher. If present, the second support section can reduce the load on the first support section, so that the first support section does not have to bear the entire weight of the skein pusher alone.

[0020] The mating element can be a bottom section on which the sliver pusher is configured to move along a movement path. That is, the sliver pusher is guided on a floor or base plate, which is a component of a spinning machine including the device according to the invention. Therefore, further use of existing components of the spinning machine is cost-effective.

[0021] A aforementioned support section may include at least one pulley. The sliding surface of the pulley is configured to roll on an associated mating element. Alternatively or additionally, the pulley is form-locked into the associated mating element. This can be achieved by means of a spherical sliding surface that rolls within a groove-like recess in the mating element. This is a very simple and low-cost way to guide the support roller.

[0022] Each of the aforementioned skein pushers may have a positioning section. The positioning section is designed to make it difficult for the skein, which is pressed against the predetermined direction and in contact with the skein pusher, to move toward one or both ends of the skein pusher as the skein pusher moves along the moving path in a predetermined direction.

[0023] The positioning section is preferably formed using two rollers, whose axes of rotation are parallel to each other and extend perpendicular to the vertical surface of the sliver. Furthermore, the rollers extend beyond the rest of the sliver pushing member in their arrangement area toward the sliver filling position of the device. This allows the sliver to be moved to be accommodated between the two rollers based on its circular cross-section and to move reliably along the movement path. Movement transverse to the movement path becomes difficult, which improves operational safety.

[0024] The present invention also provides a sliver can changer designed to stack incoming fiber slivers in a predetermined shape within a spinning sliver can at a filling position. Furthermore, the sliver can changer includes one of the aforementioned sliver can pushing devices. The sliver can pushing device is configured to move an empty sliver can from the insertion position to the aforementioned filling position in a predetermined direction during movement of the sliver can pushing member. This allows for automatic insertion of the empty sliver can without external intervention.

[0025] In this configuration, the skein changer can be designed to remove a full skein that may be in the filling position before the empty skein moves toward the filling position. This allows for fully automated skein changeover after the filling process is complete, without manual intervention.

[0026] In this configuration, the movement of the full sliver can is achieved by pressing the sliver can pusher against the full sliver can at an acute or right angle to the movement path of the empty sliver can (from the insertion position to the filling position). That is, the full sliver can is moved out of the empty sliver can's movement path toward the filling position. This ensures that, when the spinning machine has such a sliver can changer as an assembly, the movement path is set transverse to the fiber transport direction through the spinning machine. Consequently, the direction for pushing the empty sliver can into the insertion position and ejecting the full sliver can is parallel to the fiber transport direction through other parts of the spinning machine. This results in no sliver can protruding laterally from the spinning machine.

[0027] In this configuration, the skein pusher is preferably fixedly positioned at one end of the piston rod of the pneumatic cylinder. The skein pusher-piston rod arrangement is configured to guide along the removal path by means of a guide element. This is a very simple and low-cost feasible solution, particularly capable of moving heavy full skeins with a diameter of, for example, 1200 mm, out of the skein changer.

[0028] Finally, the present invention provides a spinning machine having one of the aforementioned sliver changers.

[0029] The spinning machine preferably has a drafting mechanism, and the sliver changer is disposed below the drafting mechanism.

[0030] In this case, the moving path extends parallel to the drafting direction of the drafting mechanism or at an acute or right angle to the drafting direction. Attached Figure Description

[0105] Figure 1 A combing machine 1, according to one embodiment of the invention, is shown, here equipped with eight combing heads. Therefore, the combing machine 1 includes support positions for eight sliver lappers 2, each positioned between a pair of supports 8. The supports 8 support or accommodate shafts or rollers (not shown) assigned to the combing heads. Above the supports 8, a light source 10 is arranged between two directly adjacent supports 8, bridging the corresponding interval (i.e., the associated combing head). Below the sliver lappers 2, it is schematically shown how the combed fiber sliver 3 is guided to the drafting mechanism below the drafting mechanism cover 4. Behind the fiber sliver 3 is a channel 9 for extracting the combed fiber material. Below the drafting mechanism cover 4 is a sliver can storage system or sliver can changer coiling head 5, which, in the illustrated example, fills sliver cans 6 with combed and drafted fiber sliver. The combing machine 1 also has an operating terminal 7.

[0106] Figure 2The drafting mechanism section of the combing machine 1 is shown. The drafting mechanism cover 4 is located on a housing with walls 13, which surrounds not only the sliver changer but also the coil head for stacking fiber slivers into the sliver cans 6. A platform 14 is present on the front of the housing to allow one person to operate the drafting mechanism. A cover plate 18 is located on the left side of the drafting mechanism cover 4. A ramp 17 is present on the left side (output side of the combing machine 1), which will be described in more detail later. To convey the combed fiber sliver to the drafting mechanism, a ramp 16 is constructed on the right side of the drafting mechanism in a known manner, along which the fiber sliver is guided from the combing position to the drafting mechanism. Furthermore, a conduit 15 is visible, through which the combed fiber material is guided toward the aforementioned extraction channel 9, not shown here. On the upper side, a profile-shaped deflector section 11 with a triangular cross-section for mounting light sources 10 is present on the drafting mechanism cover 4. Illumination elements 12 are arranged in a row on the side of the deflector section 11 facing the other parts of the drafting mechanism cover 4.

[0107] Figure 3a and Figure 3b Shown in two partial views Figure 2 The section on the left involves the drafting mechanism on the output side of the combing machine.

[0108] Figure 3a The left-hand area of ​​the output side is shown here, which also corresponds to the sliver can push-in side of the comber 1. This means that the sliver can 6 (not shown) is pushed toward the rear wall 23 by ramp 17. To prevent the sliver can 6 from being pushed too far, there are three plate-shaped stops 26 mounted or constructed on the output-side side of wall 23. The left end of wall 23 is adjacent to wall 22, which extends from wall 23 toward the output side or ramp 17. Wall 22 has a slit 22a extending here parallel to the bottom plate 19 of comber 1. In the operating state shown here, the arm (not shown) of sliver can pusher 27, which extends parallel to wall 22, is pushed into slit 22a. That is, in this state, the arm of sliver can pusher 27 is aligned with or arranged toward the right-facing side of wall 22. Sliver can pusher 27 is constructed here by means of two arms arranged at right angles to each other, with a diagonal brace 27a constructed between these two arms. The diagonal brace 27a preferably extends complementaryly to the outer edge of the strip tube 6 to be pushed in at its edge facing the slope 17. This prevents the strip tube 6 from being pushed in. Figure 3a The middle is pushed too far to the left. The sliver pusher 27 has a follower 57 at the right end of the mounting section 27d (behind the support column 21), which will be described in more detail later. Rollers 24 are also visible on the retaining part 25, which is rotatably arranged in the area of ​​the support column 21. That is, the area shown here corresponds to the insertion position of the empty sliver 6 in the combing machine 1.

[0109] Figure 3bThe right-hand area of ​​the output side is shown, which also corresponds to the can ejection side of the comber 1. Below the drafting mechanism cover 4 and the cover plate 18, there is a space between the two walls 23, 13 and the support 21, in which the cans are filled with fibrous material. That is, the area shown here corresponds to the filling and ejection positions of the cans 6 of the comber 1, which are for filling with fiber slivers or are already filled (full). For this purpose, the comber 1 has a can turntable 20 in this area in a known manner, which is integrated into the base plate 19. In addition, there is also a ramp 17 on the output side of the comber 1 here so that the filled cans 6 can be ejected from the comber 1. In order to reliably hold the cans 6 to be filled on the can turntable 20, in the example shown, three rollers 24 are each rotatably mounted on a bracket 25, wherein the axis of rotation of these rollers extends parallel to the axis of rotation of the can turntable 20. Wall 23 has a slit 23a extending parallel to the base plate 19, the slit being used to allow Figure 3a The follower 57 passes through. The follower 57 engages with the traction member 52, which surrounds the steering wheel 54, which is initially visible here. The movement of the traction member 52 causes the follower 57, together with the skein pusher 27, to move from the insertion position to the filling position and back again. A skein pusher 28 is arranged on the side of the wall 23 facing the ramp 17. The skein pusher 28 has the shape of a plate that curves inward, thus creating a V-shaped recess toward the skein turntable 20 or the ramp 17. If the skein 6 is filled, the skein pusher 28 moves toward the ramp 17 parallel to or perpendicular to the wall 13 or the wall 23 and in this case pushes the skein 6 onto the ramp 17. Then, the skein pusher 28 moves back to the ramp 17. Figure 3b The location is shown in the figure. For this purpose, the wall 23 has a through opening 23b through which an element for moving the strip tube pusher 28 is arranged, which will be described in more detail later.

[0110] The strip pusher 27 and the faintly visible drive mechanisms 52, 54, and 57 form a strip pusher device.

[0111] Figure 4a and Figure 4b Shown in two partial views Figure 3a and Figure 3b The strip-pushing device. Figure 4a With Figure 3a A similar view shows the skein pushing device, while Figure 4b from Figure 4a The back side of wall 23 is shown.

[0112] exist Figure 4a The follower 57 is visible in the diagram, connected to the traction member 52 based on the slit 23a. In the example shown, the follower is integrally formed on the spool pusher 27, while the steering wheel 54 is also faintly visible.

[0113] As in Figure 4b As shown, the traction member 52 also surrounds the steering section 55b of the steering wheel 55. The steering wheel 55 has a second steering section 55a on the forward-pointing side of the steering section 55b. Surrounding the steering section 55a and the steering wheel 53 is a second traction member 51. Here, a follower 56 engages on the lower return section of the traction member 51, which is mounted on the piston rod of the pneumatic cylinder 50, which is not visible here. Therefore, it is possible that the pneumatic cylinder 50, by means of the removal of its piston rod, moves the follower 56 to the right, and in this case, rotates the steering wheels 53 and 55 counterclockwise via the traction member 51. The motion is transmitted to the traction member 52 via the steering wheel 55. Because the follower 57 is mounted on the upper return section of the traction member 52, the skein pusher 27 moves to the left here. As can be seen, the steering section 55a has a smaller outer diameter than the steering section 55b. This results in a lower circumferential speed for steering section 55a compared to steering section 55b. Consequently, the travel path of the driven traction member 52 is increased many times compared to that of the traction member 51. Therefore, although the entire drive mechanism 51-57 for the canister pusher 27 does not exceed the external dimensions of wall 23, a relatively short pneumatic cylinder 50 is able to move the canister pusher 27 along a relatively large path. The pneumatic cylinder 50 and steering wheels 53-55 are mounted on wall 23 in the illustrated example.

[0114] Figure 5 Shown from the can push-in side and push-out side of combing machine 1 Figure 1The drafting mechanism section of the combing machine has a sliver can pushing device according to the second embodiment of the invention. Here, not only the insertion position of the combing machine 1 on the left is shown, but also the filling position on the right. Instead of the stop 26, the wall 23 on the side facing the base plate 19 also includes rollers 24 arranged on the support 25 in the insertion position region. The sliver can pushing member 27 here is constructed by means of three arms, which are preferably arranged in pairs at 135° angles to each other. Two rollers 27c are located on the forward-pointing arm of the sliver can pushing member 27, the rotation axes of which extend parallel to the rotation axis of the sliver can turntable 20. The rollers 27c protrude toward the sliver can turntable 20 from the forward-pointing arm of the sliver can pushing member 27, thus forming a recess between them. This recess is used to position the inserted empty sliver can 6 so that it can reliably move from the insertion position to the sliver can turntable 20, i.e., the filling position. The skein pusher 27 has a pulley 27b at its forward-pointing end, the axis of rotation of which is parallel to the plane of the base plate 19 and perpendicular to the path of movement of the skein 6 from the insertion position to the filling position. If the skein pusher 27 is moved to move the skein 6, the pulley 27b rolls on the base plate 19, thus reliably maintaining a distance between the skein pusher 27 and the base plate 19 at its forward-pointing end. In the rear region, the skein pusher 27 has a mounting section 27d, which is fastened to the guide member 38, described in more detail later. For this purpose, the wall 23 here has a recess in the lower region or is spaced apart from the base plate 19.

[0115] Through the through opening formed between wall 23 and base plate 19, a pneumatic cylinder 50 is visible, which has a follower 56 at its left end, the follower being fastened to the piston rod 50a of the pneumatic cylinder 50. In the example shown here, the skewer changer is constructed in a filling position similar to... Figure 3b In the area. The only significant difference is that wall 13 is replaced by three pillars 21.

[0116] Figure 3a In the example shown, wall 22 is replaced by railing 29.

[0117] Figure 6a and Figure 6b Show Figure 5 The skein pushing device in two operating positions. According to Figure 6aThe sliver ejector 28 is inserted. In this case, the sliver ejector 28 contacts the stop 30 on its side facing the wall 23, which is preferably mounted on or integrally formed with the wall 23. A pneumatic cylinder 33 is provided on the side of the wall 23 opposite to the sliver ejector 28, and the pneumatic cylinder is mounted on the holding part 34 of the combing machine 1 at its end opposite to the wall 23. Furthermore, the pneumatic cylinder 33 is preferably fastened to the stop 30 at its end facing the wall 23. A guide rod 32 is also visible, and will be described in more detail later.

[0118] Figure 6b The strip ejector 28 is shown in the removed position, where the associated strip 6 has been ejected. For clarity, the strip 6 is not shown. As can be seen, the pneumatic cylinder 33 moves the strip ejector 28 away from the wall 23 via its piston rod 33a through the stop 30. That is, the strip ejector 28 is secured to the piston rod 33a. To prevent the strip ejector 28 from tipping over, two guide rods 32 are provided on the right and left sides of the pneumatic cylinder 33, guiding the strip ejector 28 along its path of movement within the stop 30. This reduces the mechanical load on the piston rod 33a based on the torque generated by the strip ejector 28. The arrangement of the pneumatic cylinder 50-follower 56 with respect to the piston rod 50a is also visible.

[0119] Figure 7a and Figure 7b Shown in two views Figure 5 The strip-pushing device.

[0120] according to Figure 7a The guide member 38 is fastened to the follower 57 on the side opposite to the skein pusher 27, which is mounted on the return section of the traction member 52 in front of it. The traction member 52 then surrounds the steering section 55b of the steering wheels 54 and 55. The pneumatic cylinder 50 engages on its piston rod 50a of the lower traction member 51 in the return section behind it via the follower 56. The traction member 51 then surrounds the steering section 55a of the steering wheels 53 and 55. Here, the outer diameter of the steering section 55a is also smaller than that of the steering section 55b. Therefore, the movement path of the traction member 51 is many times longer than that of the traction member 52. The two traction members 51 and 52 are surrounded forward and upward by the housing member 31a. Thus, the drive mechanism is mechanically protected as much as possible from external influences, especially from influences related to the skein pusher 27 and the skein 6.

[0121] Furthermore, the entire drive mechanism is protected on the right and left sides by corresponding housing components 31b and 31c. Steering wheels 53 and 54 are preferably rotatably mounted on a common retainer 35, which is itself fastened to the lower housing component 31d. Steering wheels 55 are preferably fastened at both ends to retainers 36, which are fastened to housing components 31c or 31d. In the illustrated example, pneumatic cylinder 50 is preferably fastened to housing component 31c at its end opposite to piston rod 50a. Pneumatic cylinder 50 is fastened to retainer 31d at its end facing the bar pusher 27, which is mounted on or integrally formed with housing component 31d.

[0122] Figure 7b from Figure 7a The back side shows the canister pushing device, without housing components 31a and 31b. Follower 56 is clearly visible, engaging with the return section of the traction member 52 in front of it. Also visible is the staggered arrangement of the steering wheels 53 and 54.

[0123] Figure 8 Showing the use of Figure 5 The guide device of the skein pushing device. The guide rod 39 is composed of a plate-shaped fastening section 39b, which fastens the guide rod 39 to the housing member 31d, for example, by means of the bottom side of the fastening section. The guide section 39a of the guide rod 39, which has a circular cross-section, is spaced apart from the housing member 31d and integrally formed onto the fastening section 39b. The two mating guide sections 38a of the guide member 38 form-lockingly enclose the guide section 39a and are fastened to the fastening section 38b of the guide member 38. The fastening is, for example, through the fastening opening 38d. In this case, the mating guide section 38a does not completely enclose the guide section 39a within the range of its circular partial circumference. This allows the guide member 38 to pivot to a certain extent about an axis of rotation along the guiding direction of the guide section 39a. This may compensate for unevenness of the bottom surface, for example, on the base plate 19, because the installed skein pushing member 27 can pivot together with it. Preferably, sliding pads 40 are provided between the guide sections 38a, 38a and guide section 39a. Alternatively, ball bearings may be provided. A fastening opening 38c is provided for mounting the follower 57.

[0124] The present invention is not limited to the embodiments described above.

[0125] These implementation methods can be partially or wholly substituted for or combined with each other. For example, according to Figure 5 The strip-shaped pusher 27 can also be constructed to be freely suspended.

[0126] As an alternative to the steering sections 55a and 55b belonging to the steering wheel 55, a transmission mechanism can also be constructed within the frame of two meshing spur gears, wherein the driven spur gear has a smaller diameter than the driving spur gear.

[0127] Other drive components, such as transmission motors, can be used to replace pneumatic cylinders 33 and 50.

[0128] The movement path does not necessarily have to extend in a straight line. For example, guide rod 39 can extend in an arc. In this case, fastening sections 38b can be pivotally mounted on other parts of guide member 38, wherein the axis of rotation of these fastening sections extends perpendicular to base plate 19. The traction element can also be implemented with other elements, such as toothed drive belts and chains. Therefore, steering wheels 53-55 may have corresponding teeth.

[0129] Roller 27c can be replaced by a component with a similar construction to the skein ejector 28. Therefore, the skein ejector 28 can also be replaced by two rollers.

[0130] The tube pusher 27 can also be guided on a track preferably recessed into the base plate 19, instead of being guided on the base plate 19 (or floor).

[0131] This invention can be applied to any type of skewer changer, wherein the skewer must be moved along a predetermined movement path.

[0132] Furthermore, the present invention can be applied to any type of spinning machine having a sliver changer or sliver storage device. Examples of such spinning machines include (integrated) drawing frames, combing machines, and sliver lap machines.

[0133] Therefore, the present invention provides a simple, low-cost, and space-saving strip conveying device.
