Definitions
- the invention relates to a method for removing the thread remainder from a yarn carrier used on textile machines, on the outer surface of which there are thread layers which have not been unwound.
- the invention further relates to an apparatus for performing the method.
- the yarn carrier is guided along a straight line by means of a slide with holding mandrels arranged on it
- the essential parts are a device for clamping a thread carrier between two holding mandrels, further a knife head carrying at least one knife and a blowing device having a nozzle, by means of which the thread layers previously separated by the knife are stripped from the thread carrier by compressed air, the latter through one of the holding mandrels in quick
- These guide means have a configuration along one
- the slide guide therefore extends along a straight conveyor line, on which a loading station with means for automatic clamping of a yarn carrier between the receiving cone connected to a rotary drive and the pressing cone is arranged in series, followed by one from a cutter head with at least one Knife existing cutting station, 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 in an oscillating manner along the carriage guide 1 by a pneumatic cylinder, not shown in the drawing, which adjoins on the right side of the device outside the plane of the drawing, of which only the piston rod end 4 is shown.
- 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 support 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 slide 3, in order to set the yarn carrier 7 in rotation. which is explained below.
- a knife head 12 has at the bottom 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 outer surface of the yarn carrier 7 shown with dashed lines.
- the blades 13 move parallel to a surface line of the yarn carrier 7.
- a conical shown in the drawing Beispi l 1 - * 7 this being with its central axis at an angle oblique to the slide 1 held yarn carrier.
- 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 for fastening the nozzles and for supplying 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 feed movement of the yarn carrier 7, which is moved further 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 immediately removed by one aspirated next to the blowing station suction channel 16.
- the carriage 3 which is continuously moved throughout 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 due to its own weight, it moves into one in the drawing container not shown falls.
- the carriage 3 then travels back to the loading station A in rapid traverse in order to pick up a new yarn carrier.
