Definitions

  • This invention relates to combing machines, that is to say, in a general manner, to textile machines intended to ensure a purging operation (called combing) on a sheet of textile fibres (in particular long fibres such as wool fibres) generally prepared in the course of a preliminary carding operation.
  • combing a purging operation
  • a sheet of textile fibres in particular long fibres such as wool fibres
  • control means hitherto envisaged for imparting to the detaching cylinder of the machine such an unsymmetrical oscillating movement had numerous disadvantages from the point of view of their cumbersomeness, their complexity, their reliability and their longevity; moreover some of these proposed solutions were incompatible with the mounting of the detaching cylinder on a movable support having an alternating movement.
  • the main object of this invention is to provide machines of the type indicated which fulfill the requirements of practice, and in particular, in which the disadvantages mentioned above of the prior combing machines, are mitigated.
  • a combing machine of the type in question comprising at least one detaching cylinder actuated by control means adapted to impart to said detaching cylinder an unsymmetrical oscillating movement whose amplitude A in the direction of the evacuation of the treated sheet of fibres is greater than its amplitude A in the opposite direction
  • said control means comprise a helical pinion coupled in rotation with the detaching cylinder to be driven and mounted so as to be constantly in mesh with a cylindrical control rack, having helical teeth corresponding to the teeth of said helical pinion, whose axis is orthogonal to the axis of this helical pinion, said rack being mounted slidably and rotatably and being itself controlled simultaneously in translation and in rotation by two distinct control devices, namely, on the one hand, a translation control capable of imposing on the cylindrical rack a rectilinear reciprocating movement Whose amplitude is such that the corresponding theoretical movement of the detaching cylinder (mov
  • the single figure of the drawing represents, in perspec tive and in a schematic manner, the control mechanism of the detaching cylinder of a combing machine established according to one embodiment of the invention.
  • This combing machine is intended for the combing of sheets of long textile fibres, for example of wool.
  • this machine can be established in any appropriate manner with the only condition being that it comprise at least one detaching cylinder 1 preferably mounted on a support 1,, driven with an alternating movement shown on the drawing by the double arrow F, this alter nating movement being caused by any appropriate driving mechanism 30, for example of the rod and crank type.
  • the control means of the detaching cylinder 1 comprise a helical pinion 2 coupled in rotation, for example by a belt transmission 3, with the detaching cylinder 1 to be driven.
  • the spindle 2 of this helical pinion 2 is carried by the support 1 of the detaching cylinder and this pinion is constantly in mesh with a cylindrical control rack 4 having helical teeth corresponding to the teeth of the pinion 2.
  • This control rack 4 has its axis orthogonal to the axis of the pinion 2 and it is mounted so as to be able to slide and to rotate with respect to its axis.
  • the control rack 4 is itself controlled simultaneously in translation and in rotation by two distinct controls, namely, on the one hand, a translation control (designated as a whole by the reference CT) capable of imposing on this rack 4 a rectilinear reciprocating movement whose amplitude is such that the corresponding theoretical movement of the detaching cylinder 1 is a symmetrical oscillating movement having an amplitude equal to taking into account the alternating movement of the support 1,, of this detaching cylinder 1, and, on the other hand, a rotation control (designated as a whole by the reference CR) capable of imposing on this rack 4 a movement of continuous rotation whose direction corresponds to a rotation of the detaching cylinder 1 in the direction of the evacuation of the sheet (counterclockwise in the case illustrated in the drawing) and whose angular speed is such that the corresponding theo retical movement of the detaching cylinder 1 is a movement of continuous rotation having, for a time lapse equal to the duration of a single stroke (in one direction or the other) of
  • the translation control it is realized, by mounting the rack 4 slidably and rotatably on a shaft 6, by fixing on the drive shaft 5 an eccentric plate 7 coupled by a rod 8 to a slider 9 mounted on a shaft 10 and rigid with an axial thrust bearing 11 in which one of the ends of the rack 4 can rotate, and, preferably, by providing means permitting the regulation of the amplitude of the reciprocating stroke of the rack 4 under the effect of this translation control, which means can be constituted by housing the articulation of the rod 8 on the plate 7 in a radial elongated slot 12 along which this articulation can be moved, then immobilized.
  • the mechanical rotation control it can be constituted by making the drive shaft 5 drive, by the intermediary of a transmission comprising for example a belt 13, orthogonal gearing 14, a universal jointed shaft 15 and reversing pinions 16, and a toothed cylinder 17 oriented parallel to the rack 4, this toothed cylinder 17 being constantly in mesh with a pinion 18 angularly secured to the rack 4.
  • a transmission comprising for example a belt 13, orthogonal gearing 14, a universal jointed shaft 15 and reversing pinions 16, and a toothed cylinder 17 oriented parallel to the rack 4, this toothed cylinder 17 being constantly in mesh with a pinion 18 angularly secured to the rack 4.
  • means can be provided for modifying the transmission ratio of the rotation control, which means can be constituted, for example, by introducing into this control a ratio variator, or, again, by providing several replacement sets of reversing pinions 16 giving different transmission ratios.
  • the actuation of the detaching cylinder 1 takes place in a continuous manner by the intermediary of controls of which all the members remain constantly in mesh, that is to say without the intervention of any shocks or any discontinuity in the operation of the transmission devices;
  • the inertia of the movable pieces used in the translation and rotation controls is relatively small, which permits high speed operation of the detaching cylinder 1;
  • the overall cumbersomeness of the control means for the detaching cylinder 1 is relatively small, which permits greater compactness of the ensemble of the machine;
  • the detaching cylinder 1 can be mounted on a support driven with an alternating movement, which is advantageous for combining long fibres, in particular of wool.

  • a combing machine including a support for carrying said detaching cylinder, said support being mounted to be driven with an alternating movement perpendicular to the axis of said cylinder, wherein said translation control is arranged in a manner to impart to the rack a reciprocating movement the amplitude of which is such that the alegbraic sum, on the one hand, of the oscillating movement of the detaching cylinder due to the alternating movement of its support, and on the other hand, of the oscillating movement of the detaching cylinder due to the reciprocating movement of the rack, is a symmetrical oscillating movement having an amplitude equal to 3.
  • the translation control and the rotation control are purely mechanical controls.
  • a combing machine including a common drive shaft adapted to be driven, and wherein both the translation control and the rotation control are drivingly connected to said common drive shaft to be driven thereby.
  • a combining machine comprising an eccentric plate, a drive shaft, a rod, a slider and a slider shaft, said eccentric plate being fixed on said drive shaft and coupled by said rod to said slider which is mounted on said slider shaft, said slider being rigid with an axial thrust bearing in which one of the ends of the control rack can rotate.
  • the translation control comprises means for regulating the amplitude of the stroke of reciprocation of the control rack, said regulation means being constituted by the housing of an articulation of said rod on said plate on a radial elongated slot along which said articulation can be moved, and then immobilized.
  • the rotation control means includes a drive shaft, a transmission, a toothed cylinder and a further pinion, said drive shaft driving, by the intermediary of said transmission, said toothed cylinder which is oriented parallel to the control rack, said toothed cylinder being constantly in mesh with said pinion which is angularly secured to said rack.
