Definitions

  • the invention relates to a method of supplying fibrous material to the feed mechanism of an opening and cleaning machine where the textile fibrous material is supplied in a layer of textile fibres composed of at least two longitudinal formations arranged next to each other, which are being unreeled from circumference of at least two windings of this longitudinal formation.
  • the invention relates also to a device for carrying out the method, which consists of a feeder of at least two longitudinal formations of textile fibrous material, which is coupled with a conveyor of a flat textile fibrous material into the feed mechanism of an opening and cleaning machine.
  • the drawback of this method consists in that it is difficult to obtain uniform supply of the fibrous material to the feed mechanism of the opening and cleaning machine since the locks are put on the supply device in a haphazard way.
  • Another drawback of this arrangement consists in the practical impossibility of long-term production of highly homogeneous fibre mixtures by simultaneous processing of fibres of mutually different kinds or colours.
  • A1 is known a device for production of a fibre sheet, consisting of a feeding device for feeding short-fibred material in the shape of a longitudinal formation towards a combing device.
  • the longitudinal formation is according to one embodiment of the invention being supplied in three sheets arranged next to each other. In the invention there is not described the arrangement of the device, from which the sheets of the longitudinal formation are being unreeled.
  • the invention aims at removing or at least minimizing the drawbacks of the state of art.
  • the goal of the invention has been achieved by the method of supplying fibrous material to the feed mechanism of an opening and cleaning machine whose principle consists in that the windings of the longitudinal textile fibrous material are while unreeling by their circumference in contact with a pair of unreeling rollers where at least one of them rolls positively while the windings are separated from each other by at least a partition being located over the unreeling rollers.
  • the longitudinal formation is made as a fibre sheet or as a sliver because the preparation of the fibre sheet or sliver is a largely used technique and both the fibre sheet and the sliver are constant in volume and their use ensures a stable fibre supply to the feed mechanism of the opening and cleaning machine.
  • the fibre layer consists preferably of at least two longitudinal formations supplied at the same speed.
  • the advantage of this arrangement consists in the possibility of supplying to the feed mechanism a fibre volume superior to that contained in a single longitudinal formation. Another advantage consists in the possibility of simultaneously supplying to the feed mechanism fibrous materials of mutually different kind and colour, the mutual relation between all components of the resulting fibre mixture depending only on the specific weight of each longitudinal formation being unreeled.
  • the fibre layer consists of at least two longitudinal formations out of which at least one is supplied at a speed different from the suply speed of the other(s).
  • This embodiment is advantageous in that it permits to supply to the feed mechanism of the opening and cleaning machine a volume of fibrous material superior to that contained in a single longitudinal formation.
  • Another advantage consists in the possibility of simultaneously supplying to the feed mechanism fibrous materials of mutually different kind and colour, the mutual relation between all components of the resulting fibre mixture depending both on the specific weight of each longitudinal formation being unreeled and on the mutual unreeling speeds of the longitudinal formations involved which permits better to adjust the composition of the resulting fibre mixture after the opening and cleaning machine.
  • the supply speed of the longitudinal formation is adjustable which permits to extend the processing technique in relation to the quality, volume, weight, degree of impurities contained in, and length, of the fibres.
  • At least one of the longitudinal formations is made of a material different from that of the other longitudinal formations, and the opening and cleaning machine creates a homogeneous fibre mixture out of them.
  • At least one of the longitudinal formations is different in colour from the other longitudinal formations, and the opening and cleaning machine creates a homogeneous multi-colour fibre mixture out of them.
  • the principle of the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine consists in that the feeder consists of two unreeling rollers between which are by their circumference positioned at least two windings of longitudinal formations from textile fibrous material while over the unreeling rollers there is positioned at least one partition for separating the longitudinal formations of textile fibrous material from each other and at least one of the unreeling rollers is coupled with drive mechanism.
  • This device is simply and fully functional.
  • the partition permits to separate from each other the adjacent windings of the longitudinal formations so as to avoid their mutual interaction such as mutual getting caught of one in the other during the unreeling of the longitudinal formations.
  • the driven unreeling roller of the feeder of longitudinal formation is lengthwise separated into segments, each separately driven, and the space over each segment of the driven unreeling roller is separated by a partition from the neighbouring space over the neighbouring segment of the driven unreeling roller.
  • the driven unreeling roller is coupled with the drive, and the conveyor of flat material is in drive connection with the unreeling roller.
  • the driven unreeling roller is coupled with the drive, and the conveyor of flat material is coupled with a separate drive.
  • This arrangement permits separately to adjust the speed of each of the sections of the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine.
  • the other one of the pair of the unreeling rollers is in drive connection with the driven unreeling roller.
  • each of the drives of the device intended to supply fibrous material to the feed mechanism of the opening and cleaning machine is coupled with a control device.
  • Fig. 1 is a lateral view of the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine
  • Fig. 2 is an axonometric view of the device shown in Fig. 1
  • Fig. 3 is a detailed axonometric view of the remote side of the device shown in Fig. 2
  • Fig. 4 is a plan view of the device shown in Fig. 1
  • the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine ensures the supply to the opening and cleaning machine of fibrous material in the form of a fibre layer made as at least one longitudinal formation, for instance as a fibre sheet or a sliver.
  • the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine comprises a feeder 1 of longitudinal formation which is by means of a conveyor 2 of flat material coupled with the feed mechanism of the opening and cleaning machine.
  • the method of supplying fibrous material to the feed mechanism of the opening and cleaning machine consists in that the longitudinal formation or, as the case may be, a number of fibrous materials differing from each other in material or in colour, is continuously unreeled from the winding(s) of the longitudinal formation(s).
  • the fibre layer is in process of formation on the conveyor 2 of flat material or of the longitudinal formations.
  • the fibre layer can consist of a number of independent longitudinal formations situated next to each other, each of which is situated in an independent winding.
  • the opening and cleaning machine transforms the fibre layer supplied to the feed mechanism of the opening and cleaning machine into a homogeneous fibre mixture.
  • the opening and cleaning machine transforms the fibre layer a fibre mixture homogeneous in material and/or colour.
  • the feeder 1 of the longitudinal formation comprises a pair of parallel unreeling rollers 10 out of which at least one is in a suitable way coupled with a drive serving to drive the unreeling of the longitudinal formations from the windings seated on the unreeling rollers 10 , the longitudinal formations in the feeder 1 being unreeled by rolling on the two unreeling rollers 10 .
  • the coupling of the unreeling rollers 10 with the drive is carried out by means of a chain transmission 11 connecting the front unreeling roller 10 , considered in the direction from the conveyor 2 of the flat material, with an electric motor 12 .
  • the fibre layer to be supplied to the feed mechanism of the opening and cleaning machine consists of a number of longitudinal formation windings situated next to each other on the unreeling rollers 10 it is advantageous to separate the windings from each other by partitions 13 so as to avoid undesired mutual interaction between them consisting in the catching of the fibres of one winding in the fibres of its neighbouring winding.
  • the partitions 13 consist of flat formations oriented across the unreeling rollers 10 and separating from each other the unreeling sections of the windings as shown in Figs. 2 and 3.
  • the partitions 13 are suitably mounted on the frame of the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine.
  • each segment of at least one unreeling roller 10 is coupled with a drive; for instance, each segment is fitted with a drive of its own, and each of the segments of the other unreeling roller 10 is freely rotatable for instance on a common shaft.
  • the drive of the unreeling rollers 10 is coupled with a suitable control device.
  • the conveyor 2 of flat material is made as a belt conveyor with an endless conveyor belt 20 engaged on a first and a second end shaft 21 , 22 which are fitted with guide wheels 210 , 220 on whose circumference the conveyor belt 20 rolls.
  • the first end shaft 21 is coupled with a drive, the second end shaft 22 is freely rotatable.
  • the first end shaft 21 is connected by means of a second chain transmission 23 with the driven unreeling roller 10 of the feeder 1 of the longitudinal formation.
  • the transmission is improved by a third chain transmission 14 connecting with each other the two unreeling rollers 10 of the feeder 1 of longitudinal formation so that both unreeling rollers 10 are driven.
  • the drive of the conveyor 2 of flat material is separated from the drive of the unreeling rollers 10 and can be coupled with a suitable control device.
  • the drive of the unreeling rollers 10 and of the conveyor 2 of flat material can consist of a common control device.
  • the control device of the individual drives of the device for supplying fibrous material to the feed mechanism of the opening and cleaning machine can be coupled with the control device of the opening and cleaning machine.
  • the conveyor belt 20 On the outer side along its width, the conveyor belt 20 is fitted with transverse arms 201 which prevent the longitudinal formations being transported from sliding on the slanting plane of the conveyor belt 20 of the conveyor 2 of flat material and thus facilitate the feeding of longitudinal formations on the slanting plane of the conveyor belt 20 of the conveyor 2 of flat material even in case of steep slope conveyor belts 20 .
  • the device operates as follows:
  • the invention can be used in the preparation of fibrous material for further processing and for the production of fibre mixtures having required parameters of fibres of various types and colours.
