Definitions

  • the invention relates to a double-sided ring spinning machine with drafting devices on each side of the machine, which have several drafting device bottom rollers arranged one behind the other in the running direction of a sliver and rotating at different speeds, which can be acted upon by drive devices arranged at the machine end and at least one additional auxiliary drive device, the drafting devices each being part of a work station.
  • several of which are arranged side by side on each side of the machine and the auxiliary drive device is designed in such a way that it can be switched into the ring spinning machine without increasing the division of the work stations of the ring spinning machine or without one of the work stations having to be omitted.
  • the length of the bottom rollers in the drafting system where this problem occurs more frequently depends on various factors, such as the roller diameter, the bearing friction, the inhibition caused by pulled aprons, etc.
  • these different torsions have hardly any negative effects during normal running of the drafting units, they often lead to drafting errors when the lower rollers of the drafting unit are accelerated and/or decelerated, as is the case, for example, when the drafting units are started up and stopped. This means that depending on whether the torsion of a drafting system bottom roller is leading or trailing, thin or thick points result in the yarn, which can lead to quality losses or even thread breakages in the yarn produced.
  • a first embodiment it is proposed, for example, to equip the drafting system of a ring spinning machine with a drafting system drive on one side and with an auxiliary gear on the side of the ring spinning machine opposite the drafting system drive equip.
  • the auxiliary gear is intended to ensure that the angular positions of the bottom rollers of the drafting system are maintained even when the drafting system is starting up, running out or standing still.
  • auxiliary motors on the side of the lower drafting system rollers opposite the drafting system drive, instead of an auxiliary gear unit, through which torques can be introduced into the lower drafting system rollers.
  • At least one of the lower drafting rollers is driven at more than two drive points along its length. This means that in these known drafting arrangement arrangements, a drafting system main drive at the end of the drafting system lower rollers is expressly dispensed with, the drafting system lower rollers are driven exclusively by several individual drives distributed with respect to the drafting system lower rollers.
  • WO 2007/057148 A2 describes, for example, a ring spinning machine with long drafting systems.
  • the drafting units have both a drafting unit main drive device arranged at the end of the machine and several auxiliary drive devices arranged distributed over the length of the lower drafting rollers.
  • the auxiliary drive devices or their transmission elements have such a narrow design that it is possible to let the auxiliary drive devices engage between the work stations on the drafting rollers without increasing the spacing between the work stations of the ring spinning machine or without having to eliminate jobs.
  • the WO 2012/004779 A2 discloses a double-sided ring spinning machine with an auxiliary drive device for the bottom rollers of the drafting system.
  • the auxiliary drive device has an electric motor drive, a main gearbox and two distributor gears, one of the distributor gears being assigned to a drafting system lower roller of the drafting units arranged on one side of the machine and the other distributor gear being assigned to a drafting system lower roller of the drafting units arranged on the other side of the machine.
  • the object of the invention is to create a ring spinning machine equipped with long drafting units, the bottom rollers of which are driven in such a way that torsion of the bottom rollers of the drafting unit is largely avoided, with an additional auxiliary drive device being designed and positioned in such a way that neither the Division of the jobs of the ring spinning machine are increased nor one of the jobs must be omitted.
  • a double-sided ring spinning machine with drafting devices on each side of the machine, which have several drafting device lower rollers arranged one behind the other in the running direction of a sliver and rotating at different speeds.
  • the bottom rollers of the drafting arrangement can be acted upon by drive devices arranged at the end of the machine and at least one additional auxiliary drive device.
  • drive devices arranged at the end of the machine and at least one additional auxiliary drive device.
  • Several work stations are arranged next to each other on each side of the machine.
  • the drafting systems are each part of a job.
  • the auxiliary drive device has an electric motor drive, a main gearbox and two transfer gearboxes.
  • One of the distributor gears is a drafting system lower roller of the drafting systems arranged on one side of the machine and the another transfer case is assigned to a drafting system bottom roller of the drafting systems arranged on the other side of the machine.
  • the transfer gears are each equipped with a fastening device, which is connected to the respective bottom roller of the drafting system at a bearing point in a first intermediate space between two work stations for mounting the transfer gears. Furthermore, the transfer gears are each connected to a drive point at a second intermediate space between two work points with the respective lower roller of the drafting system in order to transmit a torque.
  • the storage function and the torque transmission function are separated from one another.
  • the drive point is designed in such a way that a torque is transmitted.
  • the storage function can be completely or partially omitted at this point due to the existing fastening device.
  • the storage function is taken over by the fastening device.
  • the fastening device ensures that the auxiliary drive device is securely fixed during the spinning operation both in the radial and in the axial direction.
  • the fastening device does not have to transmit any torque, but is only used for storage.
  • the connection between the fastening device and the bottom roller of the drafting system can be made correspondingly narrow at the bearing point.
  • the design and arrangement of the auxiliary drive device according to the invention not only ensures largely torsion-free operation of the long drafting system lower rollers of the drafting systems of the ring spinning machine and thus ensures that the operation of the work stations of the ring spinning machine is in no way negatively influenced during the spinning process, but also the Due to its compact design, the auxiliary drive device can also be easily inserted at almost any point in the drafting systems of a ring spinning machine.
  • the compact design is also achieved in that the drive and the main gear are used jointly for both sides of the machine.
  • the compact design of the auxiliary drive device also ensures that, even when the auxiliary drive device is switched on, the spindle pitch of the ring spinning machine does not have to be increased, nor do jobs have to be eliminated.
  • the auxiliary drive device is connected to one of the bottom rollers of the drafting system via transfer gears and secured by means of a fastening device so that not only drive energy can be transmitted at the drive point, but that the reaction moment of the transmitted energy is also reliably absorbed.
  • the respective fastening device is connected to the respective lower roller of the drafting system at a further bearing point at a third intermediate space between two work points for bearing the distributor gears.
  • the distribution of the bearing forces over two bearing points accommodates the narrow design of the connection between the fastening device and the bottom roller of the drafting system.
  • the drive point is preferably located in the middle between the two bearing points. The bearing points are thus arranged symmetrically to the drive point. This creates both optimal storage and optimal torque transmission. The drive point is reliably relieved of bearing forces.
  • the auxiliary drive device is preferably connected to the middle lower rollers of the drafting systems of a ring spinning machine.
  • the connection of the auxiliary drive device to the middle bottom rollers of the drafting system is particularly recommended because the middle bottom rollers move drafting system aprons, which have to overcome relatively high resistance when sliding over the deflection edges of the apron cages, which leads to a relatively high torsional load on the affected drafting system lower rollers.
  • an auxiliary drive device can also be connected, for example, to the lower inlet rollers or to the lower outlet rollers of the drafting systems of a ring spinning machine.
  • the main transmission and the transfer case are each connected via a universal joint, which is preferably covered by a housing.
  • the arrangement of such a universal joint between the main transmission and the transfer case has the particular advantage that, when changing the transfer case, no complex alignment of the transfer case with respect to the main transmission is necessary.
  • the associated housing also prevents the universal joint from being damaged at an early stage by the environmental conditions that are common in spinning mills. This means that the housing reliably protects the universal joint from flying and/or dust, which has a very advantageous effect both on the functionality and on the service life of the universal joint.
  • the distributor gears therefore each have a gear reduction which is matched to the speed of the associated lower roller of the drafting system.
  • the respective bottom roller of the drafting system can have a shaft pinion at the drive point for the transmission of the torque from the transfer case to the respective bottom roller of the drafting system.
  • the shaft pinion can be designed as a gear worked into the bottom roller of the drafting system, into which a gear of the transfer case engages.
  • the torque can be transmitted without any problems.
  • a radial support occurs only to a limited extent.
  • the axial and radial support is provided by the fastening device.
  • the fastening device for the auxiliary drive device on the housing of the transfer case has fixed locking elements, the end each with a bearing support for connecting the Fastening device are equipped with the respective drafting system lower roller at the bearing point.
  • the bearing supports are preferably each equipped with a rotary bearing, with either sliding bearings or roller bearings being able to be used as rotary bearings. Via the locking elements and the bearing supports of the fastening device, the transfer case is in each case reliably connected to the relevant drafting system bottom roller of the drafting system.
  • the ring spinning machine preferably has punches on which the bottom rollers of the drafting system are mounted, and the auxiliary drive device is preferably arranged between two adjacent punches.
  • the fastening device is equipped with tension and/or pressure elements, via which the fastening device is connected to the adjacent punches. This means that the tension and/or pressure elements reliably prevent forces from being introduced onto the fastening device, which could ultimately lead to damage to the transfer case.
  • the tension and/or pressure elements preferably absorb axial forces.
  • the electromotive drive of the auxiliary drive device is designed as an asynchronous motor.
  • Asynchronous motors of this type are tried and tested drive units that are widely used in the textile machine industry and can also be purchased relatively cheaply as series components from specialist dealers.
