Definitions

  • the present invention relates to a suctioned synchronous feed device for a card, consisting of a feed roller and a trough plate interacting therewith, which feed a fiber wool to a briseur, and a suction channel, which extends over the entire length of the troughplate or the entire axial length of the briseur and sucks the transfer point of the fiber wadding from the trough plate or feed roller to the breeze to remove dirt.
  • the object of the present invention is to develop a suctioned synchronous feed device of the type mentioned in such a way that dirt accumulations no longer get stuck in the suction channel or at least in critical areas thereof and are completely transported out of this channel, with relatively simple means, this suctioning via the entire adjustment range of the trough plate is effective.
  • the suction channel consists of a tube which extends over at least substantially the entire axial length of the breeze, at one end of which a suction source can be connected, and of a feed channel which extends from the transfer point to the tube and which over at least substantially the entire axial length of the breeze opens tangentially into the tube.
  • the suction channel in the form of a tube having a cylinder-like inner passage with a tangential opening in this tube or in this passage Supply channel, which extends over the entire axial length of the breeze, in combination with the simultaneous suction of the tube creates a kind of helical flow in it, which on the one hand keeps the walls of the tube clean, on the other hand keeps the carried dirt particles in motion and always in Direction of the suction source transported along this tube.
  • the feed channel preferably consists of two longitudinal walls, the first extending from the tube to the breeze cover and the second extending from the tube to the side of the trough plate facing the breeze.
  • the two longitudinal walls can be formed as smooth, continuous walls, so that no corners or dead spaces are provided in the entire feed channel where dirt particles could get caught. This prevents any risk of dirt accumulation falling down.
  • the tube is preferably arranged in a fixed manner on the machine frame above the breeze, the first longitudinal wall of the feed channel extending downward from the lower region of the tube and passing at least substantially tangentially into the beater cover.
  • This design of the first longitudinal wall ensures a clean tangential inflow into the tube and prevents dead corners from appearing at the transition point to the beater cover.
  • This transition point is preferably designed so that the lowermost edge of the first longitudinal wall of the feed channel extends at least substantially down to the lowest edge of the breeze cover adjacent to the transfer point. Since the lowermost edge of the briseur cover is a few cm above the lowermost edge of the trough plate, the air transported with the surface of the briseur becomes quasi blown into the feed channel so that the suction power of the suction source can be significantly reduced in this way according to the invention. In addition, it is ensured that any dirt particles moving with this air flow are captured and removed in good time by the suction flow.
  • the second longitudinal wall of the feed channel merges at its upper end approximately tangentially into the jacket wall of the tube and is pressed with its lower end preferably resiliently against the side of the trough plate facing the breeze.
  • the second longitudinal wall is resiliently opposed over the entire adjustment range of the trough plate from the first end position of the trough plate near the breeze to the second end position furthest from the breeze the side of the trough plate facing the breeze.
  • This arrangement of the two longitudinal walls also creates the condition for the fact that in the first end position of the trough plate, the first and second longitudinal walls can form a diverging feed channel, while in the second end position the feed channel has either a constant cross section or a converging shape.
  • This has the advantage that the tangential flow velocity of the air into the tube can be maintained at least within reasonable limits over the entire adjustment range of the trough plate, so that the aforementioned helical flow and the desired self-cleaning effect occur.
  • the feed channel is closed at the ends by corresponding side walls.
  • Fig. 1 shows the bearing housing 10 for the breeze 11, which is driven about the axis of rotation 12 for a rotary movement in the direction of arrow 13. As indicated at 14, the breeze has teeth on its surface.
  • the bearing housing 15 In front of the breeze, the bearing housing 15 is shown for a feed roller 16 which is driven to rotate about the axis 17.
  • the feed roller rotates in the direction of arrow 18.
  • Above the feed roller 16 the so-called trough plate 19 (fiber feed trough plate) is shown, which represents a relatively rigid structure. It presses the fiber wad arriving at a fiber wad feed table (not shown) increasingly against the feed roller 16 and ensures that a compressed fiber wad is fed to the breeze.
  • the trough plate 19 is shown in the drawing according to FIG. 1 in its one end position, where it lies directly next to the breeze. From this drawing it can be seen that in the transfer point from the feed roller to the breeze, the surfaces move in the same direction, ie in the direction of arrow 22 in the drawing, because this is a synchronous feed device.
  • the fibers combed out of the fiber wadding by the breeze are transported on its surface and transferred to the carding drum 24, which has a set of teeth and runs in the direction of arrow 23.
  • this drum has a large diameter, which is why for the sake of illustration only a small area of the drum can be seen in FIG. 1.
  • the breeze has a cover 25 in its upper region between the drum and the trough plate, this cover coming to an end at 26.
  • the tube 27 makes a slight bend and leads to a suction source.
  • This arc is schematically indicated by the circle 28, which represents the cross section of the tube after the arc mentioned.
  • a first longitudinal wall 29 of a feed channel 34 leads down to shortly before the lowermost point 26 of the breeze cover 25, where this first longitudinal wall merges approximately tangentially into the breeze cover.
  • a second longitudinal wall 31 of the feed channel 34 which is designed as a spring steel sheet and presses against the side 32 of the food tray plate facing the briseur 11, namely relatively close to its lowermost edge 33. It can be seen that the uppermost region of the second longitudinal wall 31 merges approximately tangentially into the jacket wall of the tube 27.
  • the feed channel formed by the two longitudinal walls 29, 31 has the food tray in the end position shown in FIG. 1 denplatte in the direction of the tube 27, given by the pivotability shown by the arrow 50 of the trough plate 19 about the axis 27 of the feed roller 16, a diverging shape.
  • a suction source is connected to pipe 27 (at 28) and sucks air through this pipe 27.
  • the briseur carries a considerable amount of air with him, this amount of air flowing into the feed channel 34 after the lowermost edge 26 of the briseur cover.
  • the fiber wadding compressed between the feed roller and the trough plate is air-permeable to a certain extent despite the compression achieved, and air also continues to flow out of this fiber wadding at the transfer point, as indicated by arrow 36.
  • the air flow marked with arrow 35 and the air flow marked with arrow 36 both contain dirt particles and continue to flow along the feed channel 34 until they finally flow tangentially into the tube 27, as indicated by the arrows 37.
  • a helical flow is indicated by the arrows 38, which strokes the entire inner wall of the tube 27 and prevents dirt particles from accumulating here. Since the mouth of the feed channel 34 extends into the tube over the entire axial length of the breeze, the particles that cross the mouth of the feed channel into the tube with the air flow 39 theoretically find a chance to flow back into the feed channel 34. However, this is prevented by the upwardly rising tangentially introduced flow 37. In this way it is possible to remove the dirt particles that are sucked off at the transition point or are removed from the teeth of the breeze or the peripheral air moving with it, so that no dirt particles can fall back to the transfer point.
  • Fig. 2 shows the arrangement after the trough plate has pivoted about the axis of rotation 17 of the feed roller in its second end position. This adjustment is made in order to adapt to the stack length of the fibers to be processed.
  • the trough plate not only has the two end positions, but it can be attached in any position between these two end positions.
  • the pan plate itself is designed as described in our European applications 87 118 415.6 and 87 118 414.9. It is essential in the present description that the second longitudinal wall 31 pressed resiliently against the feed tray plate also presses in the second end position (and in all intermediate positions) against the side 32 of the tray plate facing the breeze.
  • the feed channel 34 projects so far beyond the trough plate 19 that the end faces of the channel 34 are covered by cover plates 41 in such a way that the two cover plates are firmly connected to the longitudinal wall 29, but project beyond the longitudinal wall 31 in this way that the cover plates also form a cover when the feed channel 34, as shown in FIG. 2, has the greatest width.
  • the reference numeral 42 represents a guide plate that the Threading the fiber wadding between the trough plate and the feed roller easier. After this threading, the sheet can be folded down onto the surface of the fiber wadding.
