Definitions

  • the present invention relates to a transport channel for fiber flakes according to the preamble of claim 1.
  • German Offenlegungsschrift No. 1 510 413 It is known from German Offenlegungsschrift No. 1 510 413 to load two parallel columns of cards by means of a transport channel with fiber flakes. It is also already known from this laid-open specification to supply a column and a parallel row of cards with fiber material by means of a transport channel.
  • the transport channel runs in two straight pieces parallel to the columns parallel to one another or parallel to the column and row of cards.
  • the channel has a U-shaped, gently curved section as a connection from one straight section to the other straight section.
  • the channel section extending from the delivery station to the first filling shaft must be relatively long (at least three meters). This is avoided by the special embodiment of the present invention according to claim 8.
  • the point arranged in front of the first filling shaft of an abrupt change in direction of between 70 ° and 110 °, and thus also this filling shaft can be connected to the delivery station via a short duct section. The space that becomes free due to the relatively long piece of duct that is no longer required is thus free for other use.
  • Fig. 1 shows a transport channel 11 and filling chutes 12, 13, 14, each of which belongs to a carding machine, not shown.
  • the channel 11 has a substantially constant, rectangular cross section. It is open through openings 15, 16, 17 to the shafts 12, 13, 14.
  • the openings 15, 16, 17 are rectangular in shape. Their width is essentially the same as the width of the channel 11.
  • a transport medium flowing through the channel 11 during operation serves to transport fiber flakes.
  • the transport medium flows from left to right in Fig. 1, i.e. from the channel part 34 to the channel part 35.
  • the channel 11 in front of the shaft 12 or the opening 15 has an abrupt change in direction of 90 °. This is formed by a bend.
  • the parts of the one side wall which are at an angle of 90 ° to one another, along the perpendicular edge 18, and the parts at right angles to one another of the other side wall of the channel 11 along the perpendicular edge 19.
  • control plates 26, 27 are provided, which are located inside the channel 11.
  • the design and mode of operation of these control plates are described in detail in EP-A-0 175 056 and it is hereby pointed out.
  • the control plate 26 can be pivoted about an axis 30, the control plate 27 about an axis 31 and can be fixed in any pivot positions.
  • a barrier wall 28 or 29 is attached at their ends facing away from the axes 30, 31, a barrier wall 28 or 29 is attached. The latter extend in a slot 32 and 33 through the channel floor. They are of such a length that they remain immersed in the respective slots 32 and 33 in all pivot positions of the plates 26, 27.
  • a fiber flake-transporting medium flows from the channel piece 34 against the channel piece 35 under the assumption made above, wherein each of the shafts 12, 13, 14 is fed with fiber flakes through the openings 15, 16, 17.
  • a channel is normally allocated considerably more than three shafts. So that the flake material is supplied to all shafts, especially the rear, last, in a flawless manner and no accumulation and no jam of flakes occur over the entire length of the channel, the transport medium must have a relatively high Ge on the inlet side, in the channel piece 34 to have speed. This in turn harbors the risk that the flakes fly above the first of the openings, the opening 15, and reach the shaft 12 in an insufficient amount.
  • the flakes strike the side wall of the channel 11, which extends from the edge 18 towards the shaft 12.
  • they lose part of their kinetic energy, fly more slowly and therefore sink evenly into the shaft 12 in large quantities.
  • good homogeneity of the flake material accumulated in the shaft 12 is additionally achieved.
  • the dimensioning of the transport channel is important for a satisfactory way of working.
  • a width of 17 cm and a height of 40 cm have proven to be advantageous.
  • the area in which the ratio of the width to the height of the channel is between 0.3 and 0.6 can be described as advantageous.
  • the control plate 26, which was left out of consideration above, is located immediately before the point of an abrupt change of direction with the edges 22, 23. If it is fixed in the drawn oblique position, it causes the flowing transport medium to slow down immediately behind or behind the plate 26. This also slows down the flakes.
  • the plate 26 thus also serves to regulate the kinetic energy of the flakes and thus to regulate the amount of flakes entering the subsequent shaft 13.
  • a plate-26-wall-28 combination is drawn for the flow direction mentioned above. Such combinations can, however, be provided in front of each shaft, in particular in front of the foremost shaft 12, as desired.
  • the barrier wall 28 fastened to the plate 26 can be provided, which is taken along when the plate 26 is pivoted.
  • control plates can also be provided for the direction of flow which are opposite to what has been considered up to now, i.e. is directed from the channel part 35 to the channel part 34.
  • the plate 27 pivotable about the axis 31 is such a plate. It is drawn in Fig. 1 in its open position, in which it rests on the bottom surface of the channel 11 and is practically ineffective. If desired, a barrier wall 29 extending through the slot 33 provided for this purpose is also attached to the plate 27.
  • a major advantage of the invention is that it enables different types of placement of carding machines. Some examples of such different arrangements are shown with reference to FIGS. 2, 3 and 4.
  • FIG. 2 shows a channel 44 for loading filling chutes 36 from carding machines.
  • control plates 39 pivotable about their axes 38, which can be provided depending on the requirements, are drawn.
  • the reference number 40 denotes support columns present in the carding room, which in themselves form an obstacle for a transport channel for cards 37 set up between the columns 40.
  • cards can be placed in a column arrangement between the columns 40, with the cards 37 arranged one behind the other the front of one card being adjacent to the rear of the other card.
  • a transport channel 44 can be attached despite the columns 40. In this way, usable space can be used with the arrangements known today.
  • FIG. 2 shows a series of cards which are laterally adjacent.
  • This figure shows an example in which, by means of an abrupt change in direction of between 70 ° and 110 ° of the transport channel in a column and cards 37 arranged in a row, the cards are fed through the same channel.
  • the figure also shows an embodiment according to which at least the first abrupt rich tion change is angled and at least the last is designed as a sharp arc.
  • the speed of the transport medium in the channel 44 decreases.
  • the slowdown or loss of kinetic energy of the flakes due to the described impact on the side walls of the channel 44 becomes less necessary, if not unnecessary. Therefore, in this example, the abrupt changes in direction at the beginning of the channel are formed as bends and then as sharp arcs.
  • the further back the arches can be, the further they are on the channel.
  • the channel 44 runs transversely to its longitudinal direction. There is therefore a cross supply of the same.
  • the filling chutes 36 and thus the openings are located with their long sides parallel to the channel and thus to the direction of flow of the transport medium.
  • a shaft arranged transversely to the channel 44 would be filled on one side in its longitudinal extent if there was an abrupt change in direction.
  • FIG. 3 shows a further example of the use of the space between support columns 40 which form an obstacle for the transport channel. It shows a possible course of a channel which supplies nine cards 37 under these circumstances. There are five abrupt changes in direction.
  • the flake material enters the channel from a flake feeder 41, which consists of the channel pieces 45 and the connecting lines 46.
  • the cards 37 are arranged in parallel columns and parallel rows 42.
  • a channel piece 45 extends over each row of cards 42 or their filling shafts 36.
  • the pieces 45 are connected at their ends at points of abrupt change in direction of 90 ° by the connecting parts 46 arranged perpendicular to them.
  • FIG. 4 shows an arrangement of cards in a machine room in which an angled wall 43 stands in the way.
  • the transport channel coming from a flock feeder 41 serves to supply eight filling chutes 36 belonging to cards 37.
  • the channel in turn comprises the channel pieces 45 located above a row of cards. In this example, too, these are at abrupt changes in direction of 90 ° through perpendicular to the channel pieces 45 arranged connecting lines 46 connected to each other, and in this way form the transport channel.
  • the transport channel is guided around the obstacles in the manner shown above, the possibility being provided for this by providing the locations according to the invention of an abrupt change in direction of between 70 ° C. and 110 °.
