Definitions

  • the invention relates to a method for removing the thread residue from a yarn carrier used on textile machines, on the outer surface of which there are uncoiled thread layers, the yarn carrier being clamped at least at one end in a holder and then the thread carrier held clamped and a at least one knife carrying Knife head are moved relative to each other in such a way that the free end of the at least one knife is moved parallel to a surface line of the thread carrier outer surface for the purpose of severing the thread layers at a short distance from the thread carrier surface, such that after severing the thread layers, the thread carrier and a blowing device with at least one arranged on this and directed obliquely against the thread carrier jacket surface in the direction of the free thread carrier end facing away from the holding mandrel, are moved relative to one another and by means of compressed air emerging at the nozzle, the thread number to be removed est forming, severed thread layers are stripped from the yarn carrier.
  • the invention further relates to an apparatus for performing the method.
  • the present invention was therefore based on the object of further improving the complete removal of the thread remainder from thread carriers and at the same time achieving a high degree of economy in thread removal and cleaning of the thread carrier.
  • a method with the measures according to claim 1 serves to solve this problem.
  • the yarn carrier after cutting through the yarn residues on the yarn carrier, the yarn carrier is set in rotation and freed from the thread residues by means of simultaneous blowing (compressed air) and by using a suction nozzle. At the same time, the surface of the yarn carrier is also freed of dust and small foreign bodies.
  • the device for performing the method has the features of claim 3.
  • the essential parts are a device for clamping a yarn carrier between two holding mandrels, a knife head carrying at least one knife and a blowing device having at least one nozzle, by means of which the thread layers previously separated by the knife are stripped from the yarn carrier by compressed air, whereby this is set in rapid rotation by one of the holding mandrels, a suction device and a device for releasing the yarn carrier from the rotatable holding mandrel.
  • the yarn carrier as well as the knife and the blowing device must move relative to one another with the aid of guide means.
  • these guide means have a slide which can be oscillated along a slide guide, on which a support with a receiving cone forming the rotatable holding mandrel for holding the sleeve-shaped Thread carrier are arranged on the inner peripheral edge and with a drive for the rotatable receiving cone, as well as a further support with a pressing cone forming the second holding mandrel, the latter being axially movable with the aid of a pressing cylinder in order to be moved away from the package after the thread layers have been severed , so that the severed thread layers can be stripped from the yarn carrier with the help of the blowing nozzle over the then free end of the yarn carrier with rapid rotation of the yarn carrier and can reach an unobstructed suction channel opening in the area of the yarn carrier end.
  • the slide guide therefore extends along a straight conveyor line, on which, in series, a loading station with means for automatically clamping a yarn carrier between the receiving cone connected to a rotary drive and the pressing cone, then a cutting station consisting of a cutter head with at least one knife, then a stripping station consisting of the blowing device with at least one nozzle, next to which a suction channel opens, and then an ejector station with an ejector cylinder, which can be actuated transversely to the conveying path, for pressing off the yarn carrier from rotatable receiving cone.
  • a slide 3 On a straight slide guide 1, a slide 3 is arranged to be longitudinally movable by means of two ball bushings 2. This carriage is moved by a not shown in the drawing, on the right side of the device outside the plane of the drawing, of which only the piston rod end 4 is shown, along the slide guide 1 oscillating.
  • a support 5 is arranged on the slide 3 with a holding mandrel 6 rotatably mounted therein, which is designed as a receiving cone in order to hold the sleeve-shaped and conical yarn carrier 7 on the inner peripheral edge.
  • the yarn carrier 7 is clamped between the receiving cone 6 and a further holding mandrel 8 which is arranged on the opposite side and is designed as a pressing cone and which can be moved back and forth in the axial direction with the aid of a pressing cylinder 9.
  • the loading of the device with yarn carriers 7 in this loading station A can be automated, for which purpose, for example, a shaft (not shown in the drawing) opens above the holding mandrels 6 and 8, through which the yarn carriers come down from a storage container.
  • the receiving cone 6, which is rotatably mounted in the support 5, is connected via a drive disk 10 to a drive (not shown in the drawing), for example to an electric motor fastened on the carriage 3, in order to set the yarn carrier 7 in rotation, which will be explained below.
  • a knife head 12 has three knives 13 arranged one behind the other in the conveying direction, which can be adjusted steplessly and are pressed downwards by means of spring pressure onto an inner stop, so that the free ends of the knives 13 immediately, at a distance of approximately 0.05 mm, are located above the lateral surface of the yarn carrier 7 shown with dashed lines.
  • the knives 13 thus move parallel to a surface line of the yarn carrier 7.
  • the yarn carrier 7 In order for this to be possible, in the example of a conical yarn carrier 7 shown in the drawing, the yarn carrier 7 must be held at an angle to the carriage 1 with its central axis. For this reason, the receiving cone 6 and the pressing cone 8 are arranged with their axes obliquely to the slide guide 1. This is achieved by tilting the slide 3 with respect to the slide guide 1.
  • a blowing device 14 arranged here carries two compressed air nozzles 15 arranged one behind the other in the transport direction of the yarn carrier and thus serves to fasten the nozzles and to supply the compressed air.
  • the nozzles 15 are arranged obliquely against the outer surface of the yarn carrier 7 and in the direction of the free yarn carrier end facing away from the rotating holding mandrel 6. Compressed air flows out of the nozzles 15 at about 6 bar and, due to the simultaneous advancing movement of the yarn carrier 7 moved with the carriage 3 and the rotation of the yarn carrier, the previously severed thread residue 11 is stripped from the yarn carrier and is discharged through a suction channel 16 opening directly next to the blowing station aspirated.
  • the carriage 3 which is continuously moved during the entire process, then moves into the adjoining ejector station D, in which an ejector cylinder 17 is arranged, which presses the yarn carrier 7 from the receiving cone 6, so that it falls into a container not shown in the drawing due to its own weight .
  • the carriage 3 then travels back to the loading station A in rapid traverse in order to pick up a new thread carrier.
