Definitions

  • ABSTRACT On its way to a spinning chamber a sliver is opened out to divide it up into individual fibers and is then caused to pass along a path with two parts placed at an angle to each other. Owing to the sudden change in direction as the fibers pass from one part to the other dirt particles, which are denser than the fibers, are thrown out by centrifugal force and leave the fibers through a separating opening.
  • the present invention relates to the spinning of sliver using a spinning chamber and more particularly to a method in which the sliver to be spun is fed to the spinning chamber through a feeding and opening device so that it arrives in the chamber as individual fibers for removal of dirt particles.
  • the invention also relates to various forms of apparatus for carrying out this method.
  • the term sliver is intended to mean a strand of loosely connected fibers which are capable of being opened out for feeding to the spinning chamber.
  • One object of the invention is to provide an open end spinning apparatus which is capable of processing fiber material to a certain degree of cleanliness economically.
  • a further object of the invention is to provide a cleaning process in which the fibers of the sliver to be used for spinning are separated from each other.
  • the present invention consists in a method for spinning a sliver in a spinning chamber, comprising opening the sliver and feeding it in the form of individual fibers to the spinning chamber, the fibers of the sliver passing to the spinning chamber along a path having two parts which are set at an angle to each other so as to produce a change in direction of the movment of the fibers and to throw out dirt particles through a separating opening adjacent to the adjacent ends of the two parts of the path.
  • an air current is introduced into the fibers opposite to the direction of movement of the dirt particles out of the fibers to stop fibers from passing out through the separating opening and occasioning loss of fibers.
  • the transport roller with fiber-engaging projections which serve for separating the sliver into individual fibers is arranged to rotate after spinning in the spinning chamber is to be discontinued, and the spinning chamber slows down, and fibers are removed through the openings instead of being fed into the spinning chamber.
  • the present invention also resides in an apparatus for processing textile fibers comprising means for conveying and opening up the individual fibers, a spinning chamber arranged to receive the opened up fibers from the conveying means, the conveying means being arranged to pass the fibers along a path with two portions at an angle to each other for causing the fibers to undergo a change in direction on passing through one part of the path to the next part, a dirt-discharge opening being provided at adjacent ends of the two parts of the path for discharge of dirt from the fibers, and means defining a separating edge which defines one side of the dirt-discharge opening. Therefore centrifugal forces and the resistance of the air are used to bring about an effective removal of dirt.
  • the intensity of cleaning is influenced by the angle which a radius of the roller drum, running so as to touch the edge, makes with a radially outer face of the means defining the edge. This angle should be at least 30. In order to adjust the apparatus to suit different types of material to be spun the distance of the separating edge from the roller can be made adjustable.
  • duct means can be provided defining the two parts of the path which leads from the drafting device to the chamber, the upstream and the downstream path parts having the separating edge arranged adjacent to their adjacent ends.

  • an air supply source such as a blower.
  • the air supply duct is preferably arranged so that it can be partially or-completely closed.
  • a movable closing part can be provided to block the opening.
  • the closing part can be moved into a position so as to uncover or to block the opening.
  • the action of the separating arrangement can be interrupted.
  • the closing part is arranged so that it can be moved into at least one intermediate position between the open and closed position of the opening so that the intensity of dirt removal can be set in order to be in agreemenet with the requirements of the fibrous material which is to be spun.
  • the closing part has a side facing the roller which forms a continuation of the inner profile of the housing of the roller.
  • a particularly convenient form of the invention is arrived at when the closing part is arranged at the end of a two-armed lever which pivots about an intermediate fulcrum point and whose free end is connected with a control cam for producing the pivoting movement.
  • the wall of the collecting duct supports the closing parts arranged in individual openings in it and the ducts can be displaced, for instance, slid or swung, for actuating the closing parts.

  • a sliver S is fed by means of a feed cylinder 20, which cooperates with a feed groove 21 in gripping the sliver, and the sliver is passed to an opening roller 2 which opens it up into individual fibers.
  • opening rollers are provided with needles or another form of fiber-gripping surface, for instance spikes.
  • From the supply position Z the fibers F are transported by the roller 2 as far as a fiber-removing position A, from which they pass through a supply duct 71 to the spinning chamber 7.
  • the fibers F are deposited in a fiber ring and withdrawn from the spinning chamber 7 by means of a draw-off device 72 as a spun yarn G.
  • the construction of the spinning chamber can be in various forms, whose selection is not critical for the present invention.
  • the chamber can, for instance, be a rotating spinning chamber as described in the Swiss Patent specification No. 457,216, as a rotating funnel as described in the German Pat. specification 1,142,535, as a spinning tube as described in the German Pat. specification No. 1,062,153 or as any other form of collecting surface as described, for instance, in the German Patent specification No. 1,130,741 or the British Pat. specification No. 979,962.
  • the needle roller 2 is surrounded by a housing 10 whose wall 11 conforms to the periphery of the roll 2 and surrounds it with a narrow gap. Downstream from the supply position Z, that is to say in the direction of rotation of the roller 2, and upstream from the fiberremoval position A there is a separating edge 3 on the housing wall 11. This edge defines a dirt-discharge opening 6 between the edge and the roller which serves for the removal of husks and other dirt removed by the separating edge 3 and is connected with a duct 12 which opens into a collecting space 5.
  • the collecting space 5 is preferably arranged below the roller 2 so that the separated out material can fall away under the action of gravity. For removal of the separated matter the collecting space 5 is, for example, in the form of a drawer which can be pulled out horizontally.
  • connection duct 12 For production of an air current which moves in the opposite direction to that in which the separated material moves out of the dirt-discharge opening 6, such opening is connected via the connection duct 12 with an air supply duct 4, which can, for example, open above the collecting space 5 into the connecting duct 12. Air from the atmosphere can be sucked by the spinning chamber 7 via the air supply duct 4 so that there is an air current produced whose direction of flow is opposite to that of the direction of movement of the separated materials. Such an air current holds back fibers which might otherwise emerge through the opening 6 and passes them back behind the separating edge 3 so that no fiber losses occur. It naturally follows that this air current must flow at a certain well-defined rate so that the dirt particles, which would otherwise interfere with the spinning operation, are separated while the fibers remain on the roller 2. Generally for this purpose a suitable dimensioning of the air supply duct 4 is sufficient. However, this air current can also be made adjustable for particular fiber materials or it can be supplied with an air supply device such as a blower.
  • the separating edge 3 limits the opening 6 in the housing wall 11 in the direction of rotation of the roller 2. If the radius r of the roller 2, passing through the separating edge 3, is.extended, the extended radius r and the wall 36 of the opening which merges with the duct 12 form between them an angle a.
  • This angle should have a value of at least 30 or preferably more than 30. The size of this angle a has a very important influence on the separation of dirt. If the angle a is decreased so as to be below the value mentioned, the cleaning effect is very considerably reduced.
  • the sliver S is drawn by the feed cylinder and the feed groove 21 and first passes to the supply position Z where the sliver S is engaged by the roller 2 and individual fibers are combed out of the sliver and removed from it by the fiber-engagin g means of the roller. Owing to the rotation of the roller 2 fibers and the dirt particles between the fibers pass to the opening 6. At this position the dirt particles, which are generally denser than the fibers, and therefore tend to be thrown outwards more by centrifugal force towards the surface of the fiber-engaging means of the roller 2, are thrown through the opening 6 in the housing wall 11 so that they are given the possibility of becoming separated from the roller.
  • the fibers are, however, owing to the action of the air current introduced in a direction opposite to the direction of movement of the dirt particles, entrained further by the roller 2 as far as the fiber removal position A, where they enter the supply duct 71 owing to the degree of vacuum existing in the spinning chamber 7.
  • the opening 6 and the separating edge 3 are not immediately adjacent to the supply position Z or the removal position A, but are separated from them by a part of the housing wall 1 1, since otherwise the removal of dirt or the yarn quality would be unfavourably influenced. Both for the subjection of the dirt to a centrifugal action and also for the transfer of the fibers after the removal of dirt it is necessary to provide a certain path along the housing wall 11. It has been found extremely convenient to arrange the opening 6 approximately at the beginning of the second half of the path between the supply position Z and the removal position A.
  • FIG. 4 shows an embodiment of the subject matter of the invention in which in the direction of fiber movement immediately upstream from the separating opening 6 an additional or auxiliary air supply duct 43 opens.
  • the air supply duct 43 is separated from the separating opening 6 by a wall 44 and supplies air which assists the air current introduced through the air supply duct 4.
  • the distance between the separating edge 3 and the roller 2 can be adjusted.
  • the opening wall 36 is in the form of a slide 31 whose edge adjacent to the roller 2 constitutes the separating edge 3.
  • the setting of the slide 31 in relation to the roller can be carried out, for example, by means of a setting screw 32 or anotehr suitable manually adjusted device.
  • the separating edge 3 can also be arcuate or curved if the oepning 6 should be rounded instead of being rectangular.
  • FIG. 2 Another form of the separating edge is shown in FIG. 2 in which the wall 360 of the opening is curved and the opening 6 makesan angle a with the separating edge 30. Owing to the curvature of the wall 360 of the opening this angle changes in relation to the connecting duct 12. In this manner the desired deflection of the dirt particles into the collecting space 5 is achieved.
  • the separating edge can be flattened or as shown in FIG. 2 (30) it can be rounded in order to avoid fibers being caught and retained on it.
  • dirtremoving arrangements can be provided on each roller or on only one of them.
  • the fiber supply and opening use is not made of rollers provided with needles or other fiber-gripping surfaces, removal of dirt can be brought about by placing the separation arrangement in the supply duct opening into the spinning chamber 7.
  • the supply and opening up of the sliver S is carried out by a drafting device, in whcih the sliver S first passes to the supply position Z between the pair of draw-in rollers 22 and the drafting or opening rollers 23.
  • the drafting device it is also possible to use a greater number of drafting or opening rollers. From the opening rollers 23 the separated fibers-F at the fiber removal position A are passed into the supply duct 73, 73' and so supplied to the spinning chamber 7 in an opened condition.
  • the supply duct 73, 73 is divided by a separating opening 61 into a first part 73' and a second part 73.
  • the separating opening 61 is connected with a collecting space 5 and is defined on its side adjacent to the second part 73 of the supply duct by a separating edge 33.
  • the supply duct 73, 73 is curved and preferably has at a position adjacent to the separating opening 61 a flattened cross-section, the separating edge 33 being arranged on the outer flat side of the supply duct 73', 73.
  • the degree of efficiency of the separating device is increased since the dirt particles have a shorter path to travel before they reach the separating opening 61.
  • the opening 61 is adjoined by a connecting duct 13, forming an extension of the duct part 73 lying upstream from the separating edge 33.
  • the connecting duct 13 opens into the collecting space 5.
  • an air supply duct 4 is arranged above the collecting space 5. Additionally it is possible to provide in the rear extension of the supply duct 73 opening into the spinning chamber an air supply duct 42 which assists in deflecting the current of fibers necessary for dirt removal. Instead of the air supply duct 42 it is also possible to provide such an additional air supply duct 43 in accordance with FIG. 6 leading in the direction of fiber transport and placed immediately upstream from the separating opening 61 from which it is separated by a wall 44. Air supply can be adjusted by a slide 40 or 41 and the air can simply be drawn from the atmosphere or can be supplied by an air source such as a blower. In this manner the above-described separation operation can be controlled and undesired removal of fibers can be checked.
  • the fibers F supplied from the drafting device to the fiber draw off position A first run through the duct 73' and owing to the curvature of the supply duct 73 (in the case of the embodiment of FIG. 6) upstream from the separating edge 33 undergo a change in direction before they pass into the spinning chamber.
  • the fibers F are transported by the air current produced by the degree of vacuum in the spinning chamber.
  • the dirt particles between the fibers F cannot properly participate in the change of the direction in the air current owing to their higher density and inertia and are therefore thrown into the opening 61.
  • the supply duct 73', 73 is not bent (see FIG. but has a sharp bend or angle at the separating opening 61. Owing to this sudden change in direction a very satisfactory separation of the fibers from the dirt components is obtained.
  • a common collecting duct 50, 51, 53, 57 is provided the supply of air can be made through it.
  • Such a separating device constitutes an unnecessary interference in fiber transport on the way from the feed or opening device to the spinning chamber in the case of the processing of clean fiber materials, for example, combed cotton or synthetics, where dirt separation is not necessary and in this case such processing cannot improve the yarn quality.
  • This interference leads to a reduction in quality in certain respects; it may, for example, lead to a reduction in tensile strength and in the evenness of the yarn.
  • Such an interference with the spinning process is caused when the collected dirt particles are removed pneumatically in the separating operation.
  • Such interference may lead, for example, to thick and thin irregularities which may be a cause of yarn breakage.
  • a closing part which can be moved as desired is provided for covering the opening 6 or 61 of the separating device.
  • the closing part 8 (FIG. 7) is in the simplest embodiment constructed so as to be shifted by hand.
  • the side 82 of the closing part 8 is made to agree in shape with the housing wall 11 so that in the closed position 8' the wall 11 of the housing is not interrupted in any way. If fiber material with a high shell content is to be processed, the closing part 8 is moved into the open position so that the separating device is fully operative.
  • the fiber transport is unnecessarily interfered with if the separating device is in the operational setting. This may lead, for example, to a reduction in the strength of the yarn produced and in some cases to a reduction in the evenness of the yarn.
  • the closing part 8 is moved into its closing position 8'. The fibers F removed from the fiber sliver S are therefore transported by the roller 2 from the supply position Z to the removal position A without the separating edge 3 being able to have any effect on the fibers.
  • the closing part 83 is arranged on the end of a twoarmed lever 84 which can pivot about a pin 85.
  • a spring 840 which presses against the free end of the double-armed lever 84 holds the closing part 83 in the closed position.
  • a cam 842 operated by turning the shaft 841, presses against the free end of the two-armed lever 84, so that there is a movement of the closing part 83 against the pressure of the spring 840 and the opening is uncovered.
  • the closing part 83 is so constructed that there is a correspondence in the shape in the closed position both as regards the dirt-discharge opening 6 and as regards the collecting duct 51. This construction has been found particularly convenient and is free from trouble through the deposit of dirt and fibers.
  • the cam shaft 841 can be used to operate any desired number of closing parts 83.
  • a tubular collecting duct is provided which can rotate about its axis.
  • a closing part 86 is arranged which by a rotation of the collecting duct 50 is brought into an open position or into the closed position 86.
  • the collecting duct can also be arranged to be mvoed along its axis or perpendicularly in relation to its axis so that an unblocking or blocking of the opening 6 is brought about.
  • the upper wall of the collecting duct 53 is for this purpose constructed as the closing part 54 and moreover has an opening corresponding to the opening 6. In the pushed-in position the closing part 54 closes the oepning. If the collecting duct 53 is brought into the opened or unblocked position by lateral displacement using a linkage 55, the opening 6 is no longer blocked by the closing part 54 and beneath dirt-discharge opening 6 there is the opening of the collecting duct 53 for receiving the separated dirt particles. In this embodiment of the invention as well it is possible to move the closing part into various intermediate positions.
  • the collecting duct 57 can be shifted axially. In the position shown in the drawing the dirt-discharge opening 6 is unblocked so that separation of dirt particles occurs. If, however, the collecting duct 57 is moved to the left in terms of FIG. 11, the wall of the collecting duct 57 constructed in the form of the closing part 54 is moved into the opening 6 and blocks it.
  • the separating device can also be used successfully when feed is interrupted. In order to avoid the needle or the like roller 2 continuing feeding fiber material into the spinning chamber 7,
  • the suction effect can be controlled by an air supply duct 4 which can be connected with a suction device, and/or by suitable opening or closing of the closing parts 8, 83, 86 or 54.

Opposite the opening 890 there is an opening 891 which is connected with the opening 61. In the extension of the supply duct 73, which opens into the spinning chamber 7, a tube connector 75 is provided which extends the closing part 89.

  • the removal of dirt collected in the collecting duct 50, 51, 53, 57 or the collecting space is carried out preferably using compressed air or vacuum. It is also possible to operate with a mechanical device, for example a conveyer belt moving in the duct which continuously removesthe dirt. Such a device is, however, complicated in construction.
  • the spinning process may not be influenced by it though the collecting duct is connected via the dirt-discharge opening 6 or 61 with the spinning device. For this reason the removal of dirt is not continuous and is undertaken from time to time in such a manner that the dirt-discharge opening 6 or 61 as the case may be, which connected with the collecting duct, closed when the removal of deposited dirt is to take place. It is only after the removal of the dirt has been carried out that the dirt-discharge opening is unblocked again. In this manner the compressed air supply or vacuum induced air flow cannot have any effect on the spinning device. Since the pneumatic removal only requires a very short time, lasting a few seconds, the spinning procedure can proceed during this time without any difficulties occurring, even in those cases in which during removal of dirt no separation of dirt from the fibers occurs.
