Definitions

  • the invention relates to a device for grinding sets of a carding or cleaning drum, as set out in the preamble of the first claim.
  • the opening roller also called the beater roller
  • the reel also called the main roller
  • the take-off roller also called the doffer roller
  • the revolving cover is each loaded with sets, which can, however, be different, especially with regard to the revolving cover, which also includes a needle set can be loaded against a tooth set of the other elements.
  • the main focus is on not having to accept any loss of quality in the fiber material, in particular no additional damage to the fibers, despite the increase in performance.
  • the service life of the "tools" with increased production output is an important criterion.
  • the service life of a tool is correspondingly shorter with higher performance, which usually results in the earlier replacement of the tool.
  • a tool that is particularly subject to the abovementioned wear law in the spinning mill is the tooth set, which is used from opening the fiber flakes to carding.
  • the card that ultimately produces the card sliver to be delivered to the line is the last machine that works with such a tool, i.e. the last opportunity to avoid fluctuations of the aforementioned kind.
  • card clothing must be replaced after a predetermined maximum wear, but in the meantime, until this maximum wear occurs, the clothing is ground with all possible grinding devices available on the market will.
  • the card must not only be stopped, but also partially dismantled in order to access such a set with a grinding tool.
  • the aforementioned device consists of a grinding element which can be moved over the entire width of the clothing rollers, which is received in a driver guided in guides and is continuously drawn over the clothing at predetermined intervals depending on the production performance and / or quality characteristics. It doesn't matter that the sets are covered with a layer of fibers.
  • This disadvantage eliminates the present invention in that sharpening means are provided on the card, which roughen or sharpen the grinding element at least after every second pass, so that in combination with grinding the set not only the set but also the grindstone or. the grinding element one Embodiments in connection with the grinding device can be found in the further claims.
  • trimmings 2 which can be a card drum, for example.
  • the grinding device 4 is essentially composed of two wing parts 5 and a housing 7 located between them but integrating the wing parts 5.
  • the wing parts 5 each have a cavity 6.
  • a carriage 9 for the movements over the sets is guided by means of guide bars 8, the guide bar 8 being part of the housing 7.
  • the carriage 9 has one on both sides, as seen in FIG. 1 upper guide flange 11 and a lower guide flange 10.
  • a leaf spring 13 is fastened to the upper right guide flange 10 (seen with a view of FIG. 1) of the driver 9 by means of an intermediate piece 12.
  • This leaf spring 13 serves to receive a grindstone 20 by means of which the clothing tips are ground.
  • the carriage 9 In order to move the carriage 9 together with the grindstone 20 over the sets for the abovementioned grinding, the carriage 9 is connected by means of a driver 57 to an inner run 17 of a drive belt which is guided around a drive and deflection roller 24 and in the lower one for the drive thereof Area has an outer strand 16.
  • the drivers 57 are fixedly connected to the inner run 17 by means of screws 58 and to the carriage 9 by means of screws 59. So that the grindstone 20 is largely free to move, the leaf spring 13, as well as a leaf spring 13.1 mentioned later, each have a spring bar 131 with the width H, which connects the part connected to the intermediate piece 12 and the part connected to the grindstone.
  • the width H can be determined empirically.
  • the outer run 16 of the drive belt is guided by means of an outer belt guide 18 and the inner run 17 by means of an inner belt guide 19.
  • the belt guides 18 and 19 each have slots in which the drive belt can be guided.
  • the drive belt has a filler coating 22 which is applied over the entire length of the drive belt, except where the grindstone 20 is located.
  • the filling layer borders on both sides of the grindstone 20 and has the purpose of filling the space before and after the grindstone, seen in the longitudinal direction of the drive belt, between the inner belt guides 19, essentially in such a way that no fiber accumulations can develop there.
  • the drive and deflection roller 24 has a drive shaft 25 and an axis 26, which are each rotatably mounted in the housing 7.
  • FIG. 3 shows the carriage 9 including the stone 20 which is in the end position of its path. This end position is reported to a control unit (not shown) by means of a limit switch 28, the cam 29 of which is moved by the stone 20.
  • a proximity initiator can also be used.
  • a link guide 15, already shown in FIG. 1, is shown, which guides a leaf spring end 14 of the leaf spring 13 into this end region of the driver path.
  • FIG 3 shows a diamond rake 31 and a diamond roller 35, although in practice only either the diamond rake 31 or the diamond roller 35 would be used.
  • the diamond rake is held in a carrier 32, which is guided in the drum and by means of two compression springs 33 against the Grinding stone 20 is pressed, but not further than a path limiter 34 allows.
  • the link guide 15 is, as shown in FIG. 3, drawn towards the card clothing 2 so that the end part 14 of the leaf spring 13 is guided by this link guide 15 when the stone 20 is guided over the diamond rake 31. Due to the force of the spring 21 or the springs 23 and the guide by means of the link guide 15, the stone 20 is fixed in its position when crossing the diamond breaker 31, so that only the diamond rake can be moved and, as already described, by the springs 33 against the Stone 20 can be pressed.
  • the diamond roller 35 can be used, which is rotatably mounted in a carrier 36, which in turn is guided in a guide element 37 which is fastened to a carding flange 30.
  • a compression spring 38 is provided for pressing the grinding roller 35 against the stone 20, the stroke of which, analogous to the path limitation of the diamond rake 31, is limited by a path limiter 39.
  • the diamond roller 35 is driven by a drive 40.
  • FIG. 6 shows a variant of the diamond roller arrangement of FIG. 3 as the carrier 36.1 not against the stone 20 but through a spindle 42 is moved, which is driven by a spindle motor 41.
  • the spindle motor 41 is fastened to the guide element 37.1, which in turn, like the guide element 37, is fastened to the card flange 30.
  • the diamond roller is driven by a drive 40.
  • the advantage of the housing 7 being closed off by the drive belt and the stone 20 is that the interior of the housing 7 cannot be filled with fibers.
  • grooves 46 are provided in the guide surfaces of the slot, so that the air can advance between the guide surfaces and the drive belt surfaces, which prevents only one of the guide surfaces from being exposed to air.
  • the inner band guides 19 shown in Fig. 1 in Fig. 5 are divided into a lower band guide part 19.2 and an upper band guide part 19.1 so that the grooves 46 can be made in both band guide surfaces of the slots, the lower part 19.2 is screwed onto the upper part 19.1 by means of the screws 45.
  • FIGS. 7 and 8 show an alternative link guide in order to raise the leaf spring 13.1.
  • a pull lever 48 is pivotally mounted on the slide 9.1 in a pivot axis 53, which in turn forms part of a pivot bearing 55 which is fastened to the slide 9.1.
  • the pull lever 48 is connected to a pull rope 54, which is also connected to the leaf spring 13.1.
  • the other end of the pull lever 48 has a crossbar 49, at the end of which rollers 50 are rotatably arranged by means of axes of rotation 51.
  • the rollers 50 are each guided by the link guides 52 provided on both sides in such a way that the rollers 50 perform an upward movement, as seen in FIG. 7, whereby the pull rope 54 pulls the leaf spring 13.1 back into a predetermined position in which the stone 20 is ground either by the diamond rake 31 or the diamond roller 35. At the same time, the grinding stone is placed gently on the set.
  • the covering 22 shown in FIGS. 1 and 2 is not shown in the variants of FIGS. 7 and 8, which does not mean, however, that it cannot also be provided in these versions, but has been omitted for the sake of simplicity.
  • FIGS. 9 and 10 show the possibility of suctioning off the small amounts of grinding dust, in order to prevent this grinding dust from essentially not settling in the fiber material.
  • FIG. 9 has a suction nozzle 65 and a closing flap 60 closing it, which is pivotably mounted in the wing part 5 by means of a hinge 61.
  • the wing part 5 is, as can be seen from FIG. 9, correspondingly modified compared to the wing parts of the aforementioned figures.
  • the closure flap 60 To move the closure flap 60, it is connected to a piston rod 63 of a lifting element 62 by means of an articulated connection 64.
  • the lifting element 62 is arranged stationary.
  • the lifting element can e.g. be a magnet with spring force, the spring force closing the flap 60 and the magnetic force opening the flap 60.
  • the suction nozzle 65 has a length which corresponds at least to the entire width of the drum 1.
  • a suction channel 66 is connected to the suction nozzle 65 and opens tangentially into an air collecting line 67.
  • a suction line 68 is connected to one end of the air collecting line 67 and can optionally be provided with a fire monitor 69.
  • FIG. 10 has the same elements, except that the closure flap 60 of FIG. 9 is replaced by a closure lip 70, which is part of a closure element 71 which furthermore has a fastening leg 72 which can be fastened by means of a fastening 73 (only with dash-dotted lines indicated) is attached to the wing part 5.
  • the suction through the suction nozzle 65 only occurs during grinding, i.e. in the meantime, the suction is interrupted and, as shown in FIGS. 9 and 10, the closure flap remains. the closure lip 70 closed.
  • the closure flap 60 is opened in the opening direction B, which is done by means of the controlled lifting element 62. This means that the suction through the channel 65 is synchronized with the opening of the closure flap 60.
  • grinding is either in operation, i.e. can be carried out during carding or after carding.
  • the waiting times between grinding periods must be determined empirically.
  • the grindstone is connected to the leaf spring 13, 13.1 by means of screws (not shown).
  • Figures 11 to 13 show a grindstone 20.1, which is a variant of the grindstone 20, which was shown with the preceding figures.
  • This stone 20.1 has a reduced width F compared to the stone shown in the previous figures, which is between 10 mm and 15 mm.
  • the width of the stones 20 of the previous figures is approximately 30 mm.
  • the advantage of the reduced stone width F is that the stone is less filled with grinding dust, i.e. has a self-cleaning effect in a certain sense.
  • the width of 10 mm to 15 mm should not be regarded as a restriction, but that depending on the type of stone, in particular porosity, another optimal stone width can also be determined, which would have to be determined empirically. The main thing is to find a width that has a self-cleaning effect.
  • Grinding stone 20.1 is held on the one hand by a fastening tab 74 and on the other hand by a magnetic plate 76.
  • the magnetic plate as can be seen from FIG. 11, is provided next to the grinding stone 20.1, viewed in the direction of movement A of the reel 1, so that the metallic grinding dust resulting from the grinding adheres to the magnetic plate 76.
  • a magnetic plate 76.1 can have a trough 78 for taking up the abrasive dust mentioned, which has the advantage that there is less risk of the drum set being sanded when sanding on the fiber covering the grinding dust can be rubbed away less from the fiber covering. It can be seen from FIGS. 12 and 13 that the magnetic plate 76.1 projects with both ends by the dimension W beyond the grindstone 20.1. However, this protrusion can also be provided for the magnetic disk 76. In this way, a catching surface for the grinding dust is created, which protrudes over the length L of the grinding stone 20.1.
  • a height difference G between the grindstone 20.1 and the magnetic plate 76 is shown.
  • the grinding stone 20.1 can wear within this height difference G.
  • the movements of the proximity piston 82 are registered by a contactless proximity switch 81, i.e. the distance between the proximity piston 82 and the proximity switch 81 is registered by the latter and, by means of a connecting line 84, emits signals corresponding to the distance mentioned to a controller (not shown) which, when a predetermined wear of the stone 20 is reached, emits warning signals to the operator and / or moving the grindstone 20 respectively. 20.1 stops in the starting position.
  • Fig. 6a shows the same function, but with different means, in that the shaft 90 of the motor 41 is provided at the end opposite the spindle 82 with a pulse wheel 91, opposite which is a pulse counter 92 which counts the pulses emitted by the pulse wheel 91 and emits them as signals via a connecting line 93 to a controller (not shown) which, when a predetermined wear of the stone 20 is reached, sends warning signals to the operator and / or interrupts the movement of the stone 20 in the starting position.
  • a controller not shown
