Definitions

  • the invention relates to a roving machine with an internal transport device for conveying full bobbins and empty sleeves in the area of the roving machine.
  • the aim of the invention was to clean the empty tubes of roving residues with less effort in planning work, components and control technology.
  • the invention is based on a roving machine which has an internal transport device for conveying full bobbins and empty sleeves.
  • a transport device can consist, for example, of suspension trolley trains, which extends from the wing area of the roving machine to an interchangeable area, in which full spools are exchanged for empty tubes in these suspension trolley trains. It provides for this transport device for each roving machine to be provided with a device which is only assigned to it for removing roving remnants from spun roving sleeves.
  • the device is integrated in the roving machine in such a way that it represents a subassembly of the roving machine which is carried by its machine frame and is controlled by the control of the roving machine or at least has an interface for controlling the roving machine.
  • the device for removing roving residues on the transport path of empty sleeves is arranged from the assembly point of the transport device to the change-holding position of an empty sleeve closest to the assembly site, the advantage is achieved that only cleaned sleeves are fed to the changing area of the roving machine and that the exchanged sleeves do not have to be additionally moved to feed them to the cleaning device.
  • a particularly economical mode of operation of the device for removing roving residues is achieved if it only works on empty sleeves covered with roving residues.
  • This can be achieved by means of a sensor which senses empty sleeves supplied without roving residue and is so operatively connected to the device that it does not allow it to act on such empty sleeves.
  • the arrangement can also be such that the sensor optimizes the cleaning process depending on the amount of roving residue detected, i.e. not hastily performing if the time available does not require it.
  • the device for removing roving residues can be designed in any known form. It can be set up to suck off roving residues, unwind, brush off, stripped or otherwise removed in a suitable manner without damaging the sleeve.
  • the sensors can also be designed in any known form. They can be optoelectronic sensors interacting with reflective foils on the sleeves or video surveillance devices.
  • the sensing range of the sensors is advantageously in the area from which the winding begins, in the case of sleeves equipped with Velcro, directly on the Velcro.
  • two overhead conveyors 4 and 5 run through the wing area 2 of a roving machine 1, to which a can field 3 is assigned, in which suspension trolley trains (not shown in FIGS. 1 to 3) can be moved, by means of which full runners in the roving machine Coils can be exchanged for empty tubes.
  • the type and mode of operation of such a bobbin changing device are known from DE 42 29 296 A1, to which reference is made in this respect.
  • the suspension tracks 4, 5 are connected via connecting tracks 6 and switches 7 to a ring suspension track 8, the two strands 9 and 10 of which extend parallel behind the roving machine 1.
  • a converter 11 is arranged, which converts full spools of hanging trolley trains running in the ring monorail into another monorail 12 and empty sleeves made of monorail trains of this monorail in monorail trains of the ring monorail.
  • the further monorail 12 leads into a processing or storage area, not shown.
  • This processing area can consist of ring spinning machines, in the gates of which the full bobbins are processed and return to the spinning machine 1 as empty bobbins.
  • the storage area can consist of an arrangement of overhead conveyor sections, in which overhead trolley trains can be parked with full spools or with empty sleeves until further processing.
  • a device 13 for removing roving residues - hereinafter called cleaning device for short - is provided.
  • this cleaning device 13 is arranged separately from the roving machine 1 on the course of the ring suspension track 8. It has been assumed that the suspension trolley trains rotate in the counterclockwise direction during the transfer process in the ring suspension track. The cleaning device 13 is therefore set in the direction of travel of the suspension trolley trains immediately after the converter 11 in the ring suspension track 8.
  • the overhead trolley trains run counterclockwise in the ring suspension track 8, the converter 11 each having one or two full spools from a suspension trolley train in the ring suspension track into a suspension trolley train of the suspension track 12 and one or two empty spools from a suspension trolley train of the suspension track 12 in one Hanging carriage train of the ring suspension railway 8 implements.
  • the empty sleeves pass the cleaning device 13 and are thereby freed of remaining roving residues, so that there are only empty sleeves free of roving residue in the hanging trolley trains in the ring suspension track 8. It goes without saying that the cleaning device 13 does not operate when passing overhead trolleys with full bobbins.
  • the cleaning device 13 is indeed separate from the roving machine 1, but is only assigned to the roving machine by arranging it on the ring suspension track 8 and only cleans empty tubes on this roving machine.
  • the cleaning device 13 is self-sufficient, i.e. in its structure, its energy supply etc. completely independently and in the control of its operation only depends on the circulation of the empty sleeves in the ring overhead conveyor 8. It can therefore be offered as an option for the roving machine 1 or can also be subsequently delivered to a roving machine.
  • the cleaning device 13 is integrated in the roving machine 1, i.e. it is constructively and functionally part of the roving machine.
  • the ring suspension track 8 is guided through the machine frame 14 of the roving machine.
  • the mode of operation of the cleaning device 13 is also controlled only indirectly from the pre-spinning machine 1 in accordance with the movement of the hanging trolley trains with empty sleeves in the ring overhead conveyor 8.
  • the circulation of the hanging trolley trains in the ring suspended conveyor 8 takes place here clockwise.
  • the roving machine 1 has a bobbin changing device in which the suspension tracks 4 and 5 do not open into a ring suspension track, but rather are each extended into a parking track 15 and 16, respectively. Beneath these parking tracks 15, 16, an endless chain 18 is guided in a bank 17 that can be raised and lowered, which takes over full spools of hanging trolley trains standing in the parking tracks or latches empty sleeves into these hanging trolley trains. The endless chain 18 is guided to the converter 11, which, as described above, exchanges the full bobbins and empty tubes into and out of the overhead conveyor 12.
  • the cleaning device 13 is here also formed as part of the pre-spinning machine 1 and arranged so that the chain 18 runs through this cleaning device.
  • the chain 18 also rotates clockwise here.
  • FIG. 4 a rail of the ring suspension track 8 or one of the parking tracks 15, 16 is shown at 9, in which a suspension carriage train 19 can be moved by means of pairs of rollers 20.
  • the method is brought about by pairs of friction wheels 21 which can be driven by electric motors 22.
  • the empty sleeves 24 can be set in rotation in the working position by means of a pair of rollers 27 which can be driven by an electric motor 26.
  • a suction nozzle 28 Arranged on the path of movement of the empty sleeves 24 is a suction nozzle 28 which extends over the entire winding height of the sleeve and is connected via a rotating sieve drum 29 to a suction source in the form of a fan 31 driven by an electric motor 30.
  • a narrow suction nozzle which follows the suction point and thus exerts a higher suction effect.
  • the rotary drive of the screen drum 29 is not shown here for the sake of clarity. Below the screening drum 29 there is a collecting container 32 for drawn roving threads.
  • An optoelectronic sensor 33 is also attached to the path of movement of the empty sleeves 24 and scans the empty sleeves 24 passing by for the presence of roving residues 25.
  • the sensor 33 can be directed onto a Velcro strip 34 on the sleeve and can be designed such that it can recognize the difference in color or brightness between a Velcro strip that is free of roving residues and a Velcro strip that is covered with roving.
  • the sensor 33 can also be directed at a reflective film 35 arranged on the sleeve and can be designed in such a way that it can recognize the difference between a reflective film which is free of roving residues and a reflective film which is covered with roving.
  • the sensor 33 is connected to a control device 36 which controls the electric motor 22 of the friction wheel pair 21, the electric motor 26 of the pair of rollers 27 and the electric motor 30 of the fan 31.
  • the sleeve exchange device 37 consists of a double-arm swivel arm 39 which can be swiveled by 180 ° in its longitudinal center about a vertical axis by means of an electric motor 38 and at the ends of which sleeve grippers 40 are arranged in the form of pins which can enter the tubular sleeves from below.
  • the swivel arm 39 can also be raised and lowered by means of a further electric motor 41, which engages with a pinion 42 in a rack 43.
  • An empty sleeve magazine 44 in the form of a disk 46 which can be rotated by means of an electric motor is assigned to the swivel arm 39, on which empty sleeves 24 free of roving residue are kept by means of hanging holders 23.
  • a sensor is assigned to the sleeve exchange device 37, which can be the same sensor 33 that is described in connection with the cleaning device 13. The sensor is in turn connected to a control device, which can also be the control device 36 already described. The control device 36 is still connected to the electric motors 38, 41 and 45 here.
  • the sensor scans the empty tubes 24 for remaining roving residues. If he detects a roving residue, he sets the suspension trolley train so quietly via the control device 34 by actuating the electric motor 22 driving the friction wheel pairs 21 or prevents it from continuing to run so that the sleeve is located in front of the suction nozzle 28. At the same time, he switches on the electric motor 26 of the pair of rollers 27 and the electric motor 30 of the fan 31, so that the remaining roving residues are unrolled from the empty sleeve or in the working position and suctioned off.
  • the sucked-off roving residues fall from an area of the sieve drum 29 covered against the suction draft into the collecting container 32. If several suction points 37 are provided, these steps take place in parallel at all suction points.
  • the cleaning device 13 can act on an empty sleeve for a measured period of time, which is normally sufficient to remove remaining roving residues.
  • an optoelectronic sensor in the suction nozzle 28 or in a channel adjoining it in a manner not shown, which responds when no roving is sucked off and, as a result, the suction stops. If the sensor 33 determines after the allotted time that the empty tube still contains roving residues, it causes the replacement of this tube, which obviously does not have to be cleaned automatically or cannot be cleaned completely within the intended cycle time, by a tube free of roving residue from the empty tube magazine 44.
  • control device 36 For this purpose causes the control device 36 by switching on the electric motor 41 lifting and lowering the swivel arm 39 and thus disengaging the empty sleeve with roving residue from the hanging trolley 19 and an empty sleeve with no roving residue from the empty sleeve magazine 44.
  • the electric motor 38 By switching on the electric motor 38, the swing arm 39 is rotated by half a turn and thus castles the captured sleeves.
  • the electric motor 41 is switched on again, the swivel arm is raised and lowered again, and the empty sleeves are thus latched into the hanging trolley train 19 or into the empty sleeve magazine 44.
  • the disk 46 By switching on the electric motor 45, the disk 46 is then rotated further by one division and thus a new empty sleeve free of roving residue is brought into the change position.
  • the empty sleeve with roving can be removed from the empty sleeve magazine 44 by hand, cleaned and hung again in the empty sleeve magazine.
