Definitions

  • the invention relates to a device for orienting conical yarn tubes in the same direction, with a feed device for placing individual, lying yarn tubes, with a downstream, inclined surface with a direction of inclination transversely to the longitudinal axis of the tube and with a loading element that follows the inclined surface and accommodates the oriented yarn tube.
  • the empty sleeves must be oriented in order to load the sleeve carriers of automatic bobbin changing devices on spinning machines, i.e. in the case of conical sleeves with their thicker ends, they should be guided onto the mounting pins.
  • twine tubes in a tangled position require appropriate positioning.
  • the thicker end of a yarn tube is a sliding slide over a drop opening (DE 19 29 866, DE 20 47 970, JP-Sho-49-419) and bobbin turning devices (DE 26 39 531, FR 2 345 542, EP 0 276 880).
  • Other known designs use slots (DE 896 472, GB 1 187 719, DE 19 41 249) and rollers which move the thicker end of a yarn tube (EP 0 547 775).
  • the above-mentioned devices can thus be divided into non-compulsory ones, which are defective, and compulsory ones, which are structurally complex.
  • the devices can also damage the sleeves if they jam.
  • the prior art from which the present invention is based is moreover known to a machine for the automatic insertion of yarn tubes into containers for their reuse (DE 23 09 923 A1).
  • the yarn tubes are unloaded onto an inclined surface, where they roll and / or slide downward under their own weight and are gripped at the end of the inclined surface by a belt, which now supplies them to a collecting container in the end order. They are then removed individually from this collecting container by means of a rotating drum.
  • the sleeves interfere with one another, so that the end arrangement is unsafe. After orienting, the sleeves are back in bulk, from which they have to be separated again.
  • the object of the present invention is to provide a device of the type mentioned at the outset, which ensures simple, safely functioning orientation which is gentle on the sleeves, the sleeves at the end being to be delivered individually and in a precisely arranged manner.
  • This object is achieved in that a funnel leading to a loading device is arranged under the lower edge of the inclined surface as the loading element and that the drive of the feed device is connected to a control unit for individually orienting the sleeves.
  • the inclined surface can have such an inclination and such a coefficient of friction to the material of the sleeves that the sleeves advantageously only roll on the inclined surface.
  • the inclined surface can expediently have a covering with a high coefficient of friction compared to the material of the sleeves.
  • the length of the inclined surface can be dimensioned as a function of the taper of the sleeves so that the sleeves, when their center of gravity reaches the lower edge of the inclined surface, form an angle of at least 15 ° to the starting position. This ensures that each sleeve crashes with its thicker end in advance and a safe orientation takes place.
  • control unit can be connected to a timer.
  • a scanning device connected to the common control unit is arranged in the entrance area of the inclined surface and / or in the end area of the funnel.
  • a sleeve storage shaft can be arranged upstream which has an actuatable outlet and a sleeve which is located in the sleeve storage shaft and which consequently has a sensor which stops the transport element via the control unit.
  • the sleeve storage shaft can be formed by a fixed wall opposite the transport element and the outlet can be formed by the sleeve strips if the transport element is designed in the form of an endless, essentially vertically running conveyor belt provided with transverse sleeve strips.
  • the shaft can store a probe arm connected to a microswitch in the lower area as a sensor.
  • the sleeve strips can each have an outwardly inclined support surface for a sleeve lying in the sleeve storage shaft.
  • the device 1 is shown schematically for orienting conical yarn tubes 3 in the same direction in a position lying ahead with the thicker tube end.
  • a transport element 2 in the form of an endless, essentially vertical conveyor belt 9 provided with sleeve strips 4 lying one behind the other is used as the feed device.
  • This transport element 2 is arranged downstream of a tube container 40, in which the conical yarn tubes 3 are in a tangled position.
  • the transport element 2 is followed by an inclined surface 5, with the direction of inclination transverse to the longitudinal axis of the tube and with a loading element 6 which adjoins the inclined surface 5 and receives the oriented yarn tube 3.
  • the loading element 6 consists of a funnel 7 which is arranged downstream of the inclined surface 5. as well as a chute 8 and a loading device 10 with receiving pins 11.
  • a conical yarn tube 3 is placed on the inclined surface 5, it rolls due to its conicity in one of the drawn arches, in which the thicker end 18 leads ahead, so that this end is already beyond the edge 13 when the thinner end 19 is still in the region of the inclined surface 5.
  • the sleeve 3 plunges with its thicker end 18 ahead over the lower edge 13 of the inclined surface 5 into the funnel 7.
  • the inclined surface 5 advantageously has such an inclination and such a coefficient of friction to the material of the sleeves 3 that the sleeves roll on the inclined surface 5 only in a defined path and do not slide in an uncontrolled manner.
  • the inclined surface 5 can accordingly have a covering 12 with a high coefficient of friction compared to the material of the sleeves 3, e.g. Rubber.
  • the inclined surface can also have a rough surface.
  • the sleeves 3 are less subject to the risk of sliding, the flatter the inclination of the inclined surface 5. On a less inclined surface, however, the sleeves 3 roll more slowly, which leads to a high cycle time for orientation. If the cycle time is to be short, a greater inclination of the inclined surface 5 must be provided. This is particularly possible if the inclined surface 5 has a high coefficient of friction compared to the sleeves 3. Accordingly, the angle of inclination of the inclined surface 5 to the horizontal should be between 15 ° and 30 °.
  • the sleeves must be fed individually to the inclined surface 5 by the feed device 2.
  • a control unit 15 is provided which controls this feed. If the sleeves have a known passage time through the device, the feed can take place at a fixed time interval.
  • the control unit 15 contains an adjustable timer which determines the rate at which the sleeves are fed.
  • a scanning device 17 designed as a sensor, which senses that a sleeve has been fitted onto the charging device 10 and consequently causes the next sleeve to be ejected.
  • the control unit 15 is activated, which activates the drive 30 for the feed device 2 accordingly, so that a further sleeve 3 is moved upward over the sleeve strips 4 and is dropped on the inclined surface 5.
  • a sensor can also be arranged in the input area 14 of the inclined surface 5 as a scanning device 16, which feels the application of a sleeve and keeps the feed device 2 actuated via the control device 15 and the drive 30 until this is the case.
  • the inclined surface 5 is preceded by a sleeve storage shaft 25 which has an actuatable outlet 26 and a sensor 24 which senses a sleeve which is ready in the sleeve storage shaft 25.
  • the feed device 2 designed as a conveyor belt 9 can be stopped.
  • the storage shaft 25 is advantageously formed by a fixed wall 27 opposite the conveyor belt 9; the outlet 26 results from the sleeve strips 4 '. Accordingly, these sleeve strips 4 'each have a back surface 31 for a sleeve lying in the sleeve storage shaft 25. This bearing surface 31 is inclined downward from the conveyor belt 9, so that a sleeve no longer held by the shaft wall 27 falls onto the inclined surface 5.
  • the shaft 25 has a cutout 24 in the lower area, in which a probe arm 30 connected to a microswitch 28 is mounted as a sensor.
  • a yarn tube 3 transported by the transport element 2 falls into the tube storage shaft 25, this yarn tube 3 lies on the rear bearing surface 31 of the tube strip 4 ', whereby the probe arm 32 is lifted and the microswitch 28 is actuated.
  • the transport element 2 is stopped via the control device 15, so that this sleeve remains in standby at the outlet 36 of the shaft 25. If the drive of the transport element 2 by the scanning device 17, which is designed, for example, as a light barrier is switched on again, the sleeve ready in the sleeve storage shaft 25 is immediately thrown onto the inclined surface 5, orients itself on it, falls through the funnel 7 and into the chute 8 and is placed on the loading device 10, ie the receiving pin 11 .
  • the embodiment according to FIG. 4 shows the inclined surface 5 in a top view.
  • the length of the inclined surface 5 is dimensioned depending on the taper of the sleeves 3 so that the sleeve 3, when its center of gravity reaches the lower edge 13 of the inclined surface 5, is at an angle of at least 15 ° to the starting position. This ensures proper orientation of the conical sleeve over the inclined surface 5 and its corresponding dimensioning.
  • the embodiment according to FIG. 4 further shows the effect of lateral boundary surfaces 20, 21 on the inclined surface.
  • the distance between these boundary surfaces 20, 21 from the ends of an empty sleeve 3 placed on the inclined surface 5 is selected such that a rolling sleeve with momentum abuts with its thin end 19 against the boundary surface 21 and now surrounds the contact point on this boundary surface turns. It is thereby achieved that the sleeve 3 very soon one in the direction reached the inclination of the inclined surface 5, which it would only achieve without the lateral boundary surfaces 20, 21 (approximately as in FIG. 1) with a much deeper and wider inclined surface and which an absolutely safe fall with the thicker end 19th guaranteed ahead.
  • a sleeve is prevented from rebounding after starting on one of the boundary surfaces 20 and 21 and itself moved uncontrollably. If a sleeve 3 rotates during pivoting about the contact point on the boundary surface, it reaches a position in which it falls into one of the grooves 22 or 23. This fixes its orientation and it slips quickly and securely into the funnel 7 in this channel. It is also advantageous to provide the boundary surfaces 20, 21 with a soft, impact-energy-absorbing coating in order to rebound the sleeves 3 from these boundary surfaces in the embodiments 4, 5 and 6 as far as possible to prevent.
  • FIG. 7 there is also the possibility, instead of the feed device 2 shown in FIG. 1 in the form of a conveyor belt 9 (with sleeve strips 4), to provide a sleeve container 40 which opens into a shaft 42.
  • the sleeves 3 are oriented accordingly and are individually provided with an opening 45 which is closed by a double slide 46.
  • This double slide 46 is connected to the piston of a piston-cylinder unit 43. If this piston-cylinder unit 43 is actuated, the double slide 46 opens the opening 45 for the lowermost sleeve, so that it falls in the direction of the arrow on the inclined surface 5 and is transported from there analogously to the aforementioned embodiments.
  • the invention is therefore not only limited to a feed device 2 in the form of a conveyor belt 9, further embodiments of the feed device 2 are also conceivable, but in any case it must be ensured in terms of construction that the sleeves 3 are successively on the inclined one Area 5 are thrown off.
  • the piston-cylinder unit 43 is connected to the control unit (15), which serves to individually orient the sleeves.
