Definitions

  • the invention relates to a device on a card with a migratory lid made of flat bars provided with clothing, in which there is at least one endless flexible belt for propelling the flat bars and in which the flat bars slide with their two ends on sliding guides and then on the side opposite the sliding guides can be returned.
  • the flat bars are pulled over the sliding guides with two flat chains, which are each attached to the two outer ends (flat heads) of the flat bars.
  • the lid chain is attached to a flat bar by a lid screw, which engages axially through a bush at the hinge point of the chain in a bore with an internal thread in the lid head.
  • the introduction of the internal thread on the end face of the lid head is complex in terms of production technology.
  • Another disadvantage is that the cover screw has to be tightened with a certain torque, which during assembly, for. B. after a reorganization or the like, is time consuming.
  • the invention is based on the object of creating a device of the type described at the outset which avoids the disadvantages mentioned, which in particular allows simple manufacture and assembly and enables the flat bars to be replaced quickly.
  • the ends of the flat bars are pulled forward by positive locking between the belt and the flat heads over the slide guides and when transported back on the side of the traveling cover opposite the slide guides, the flat heads lie loosely on the belt and can be removed and replaced unhindered from there.
  • the flat bars do not fall off the belt even when they are loosely placed on the belt because they engage the belt in a form-fitting manner.
  • the engagement between the belt and the flat bars can preferably be released during operation. This means that the flat bars can be replaced even when the revolving lid is running.
  • the outside of the belt expediently engages with the side of the ends of the flat bars opposite the clothing.
  • the belt preferably has lugs on the outside, which engage in recesses that are present at the ends of the flat bars.
  • the belt has depressions on the outside which engage in the lugs present at the ends of the flat bars.
  • the lugs are preferably cylindrical and the depressions are hollow cylindrical.
  • the approaches are conical, e.g. B. hollow cone-shaped. This allows the lugs to be centered when engaging in the recesses.
  • the flexible belt is preferably a double toothed belt.
  • the inside of the belt is advantageously designed as a toothed belt, which is in engagement with two toothed belt wheels.
  • cover deflecting elements there are preferably two cover deflecting elements in the area of the end face of the moving cover.
  • the cover deflecting elements are expediently curved guide and holding plates or the like.
  • a straight cover guide element is preferably arranged between the cover deflecting element and the slide guide for the introduction of the cover rods, which straight element connects tangentially to the curved slide guide.
  • the belt advantageously presses the ends of the flat bars onto the slide guides.
  • the flat bars are preferably loosely located on the side facing away from the sliding guides on the outside of the belt.
  • the belt is useful inside z. B. by tensile steel wires, glass fibers, aramid fibers or the like, reinforced.
  • the upper run of the belt is expediently provided by at least one support element, e.g. B. role, level support or the like, supported.
  • the belt preferably has lugs on the outside, the front surfaces of which each engage an outer surface of the cover heads.
  • the sliding guide is formed by a plastic element which is arranged on the side of the flexible sheet facing the ends of the flat bars and which projects beyond the flexible sheet by at least a distance a.
  • the flexible bend expediently has a recess, for. B. a groove in which the plastic element is embedded.
  • the cover deflecting elements advantageously have a recess for storing the plastic element.
  • the plastic element is preferably fastened at one end to the inlet side of the flat bars.
  • the cover deflection rollers are expediently engaged with the back parts of the cover rods.
  • Fig. 1 shows a card, e.g. B. TRÜTZSCHLER-EXACTACARD DK 740, with feed roller 1, dining table 2, licker-in 3, drum 4, taker 5, doctor roller 6, squeeze rollers 7, 8, fleece guide element 9, pile funnel 10, take-off rollers 11, 12 and revolving cover 13.
  • the direction of rotation (arrows A and B) of the front and rear cover pulley 15a, 15b (toothed belt wheels) is opposite to the direction of rotation (arrow C) of the drum 4.

  • the flat bars 14 and The flat bar heads 14a lie loosely on the outside 16a of the upper run 16d of the belt.
  • the toothed belt wheel 15a is opposite a curved guide and holding element 19, through which the flat bars 14 are held during the deflection.
  • the top Run 16d is supported by two support rollers 20, 21 and by a flat support 22.
  • the support rollers 20, 21 are designed as toothed belt wheels, which are in engagement with the inside 16b of the belt 16.
  • a straight cover guide element 23 is arranged between the cover deflection element 18 and the slide guide 17 and connects tangentially to the curved slide guide 17.
  • the cover guide element 23 is arranged before the cover 14 runs onto the slide guide 17 of the drum 4.
  • FIG. 4a shows a part of a flat bar 14 with a back part 14d and a clothing receiving part 14e.
  • the lid head 14a has a continuous hollow cylindrical bore 24 running perpendicular to the surface 14c.
  • FIG. 4e shows the belt 16, which has projections 25a, 25b ... 25n, for example made of rubber, on its outside 16a.
  • the lugs 25a to 25n engage in operation in the corresponding bores 24 in the lid heads 14a from above.

  • the lugs on the outside 16a of the belt 16 are formed, for example, by providing metal pins 30a, 30b or the like, which have one end in the belt 16, e.g. B. are attached by vulcanization un whose other end protrudes from the outside 16a.
  • the pins 30a, 30b are completely embedded in the belt 16 and serve to reinforce the projections 32a, 32b ... 32n which protrude beyond the outside 16a.
  • the card has two flexible sheets 17a; each flat bar 14 has two lid heads 14a ', 14a ⁇ (see FIG. 10), etc.
