Definitions

  • the present invention relates to a combing machine for spinning preparation with a machine frame in which at least two combing heads are arranged and having a main drive motor for driving the combing heads.
  • DE 10 2012 011 030 A1 discloses a combing head of a combing machine for use in spinning preparation, and the combing head has a drive input shaft as an essential structural component, which drives a pincer gear, the pincer gear serving to drive a pincer apparatus. Furthermore, the gear unit has detaching cylinders, and the detaching cylinders are arranged at the gear output of a planetary gear. The rotary movement of a central shaft is coupled to the gripper shaft via a rocker arm and a cam gear so that the latter performs an oscillating movement, and at the same time the central shaft also drives the planetary gear for the detaching cylinder, with the central shaft being coupled to the drive input shaft via a gear stage.
  • the combing head consequently has shafts and working cylinders coupled to the shafts and acting in different ways, which perform an oscillating movement, and in particular the detaching cylinders perform a so-called vocational stepping movement.
  • the circular comb shaft with a circular comb roller attached to it performs a rotational movement in one direction of rotation with fluctuating speed, which results in a discontinuous power consumption for a main drive motor from other, discontinuously rotating working cylinders with acceleration and deceleration phases over the comb play and these driving or receiving shafts of the transmission results.
  • Modern combing machines have, for example, eight combing heads which are arranged in a row next to one another in or on a machine frame.
  • the combing heads are operated synchronously with one another, so that some shafts, in particular the discontinuously operated shafts, can be coupled together so that they are designed to be continuous, so that several combing heads share common shafts with one another. This reduces the design effort and ensures that the combing heads run synchronously.
  • the same can be provided for the detaching cylinder.
  • EP 2 397 584 B1 shows a combing head with detaching cylinders which are each driven by two synchronously operated electric motors.
  • the dynamics in the discontinuous rotational movement of the detaching cylinder can be increased, and on each side of the detaching cylinder there is a gear, via which the respective electric motor is operatively connected to the detaching cylinder in a driving manner.
  • the power consumption of the main drive motor is characterized by a discontinuous curve due to the pilgrim step movement, the detaching cylinder and the oscillating movement of the nipper shaft, which, however, is repeated in the same way for each comb cycle.
  • the deceleration and acceleration of the shafts and the differently acting working cylinders applied to them result in a characteristic curve, with the power consumption being required both to generate a torque in a first direction of rotation and to generate a torque in an opposite direction of rotation of the motor .
  • the result is an overall high power consumption and a high energy requirement for operating a combing machine, in particular with a number of combing heads.
  • the reason for a poor balance of power is also the inability to operate the main drive motor in an operating optimum, in particular with regard to its torque, since the output torque changes periodically and repeatedly over each comb play.
  • the object of the invention is an optimized operation of a combing machine with the lowest possible power consumption.
  • several combing heads are to be operated in a row next to one another without increasing the design complexity for coupling the combing heads to one another.
  • the invention provides that a main shaft that is operatively connected to the main drive motor is provided, with the main shaft driving the at least two combing heads, with the combing heads being operatively connected to the main shaft in such a way that when the main drive motor is in operation, the combing games of the combing heads run out of phase with one another .
  • Individual combing heads can be operated further to a first group of combing heads in a first phase position and a second group of combing heads can be operated in a second phase position, the groups being drivingly connected to the main drive motor.
  • the first group of combing heads and the second Group of combing heads are drivingly connected in particular via a common gear with the main drive motor.
  • the core idea of the invention is a phase offset in the combing of at least two combing heads or of a first group of combing heads to the combing of a second group of combing heads, so that a power flow can result via the operative connections of the groups to one another, which can at least partially compensate each other.
  • the acceleration phase and thus the proportion of power consumption for accelerating the first combing head or the first group of combing heads can be partially fed by a torque that is generated by a deceleration phase of the combing games of the second combing head or the second group of combing heads.
  • the power curve is smoothed, so that the total power requirement for operating the combing machine is reduced and the main drive motor can be operated at or near an operating optimum.
  • the first combing head and the second combing head or the first gear and the second gear for driving the groups of combing heads are coupled to one another with particular advantage.
  • excess power for example in a deceleration phase of essential working cylinders in the first combing head or in the first group of combing heads, can be used to execute an acceleration phase of the essential working cylinders of the second combing head or the second group of combing heads.
  • a main shaft which couples the first combing head and the second combing head or the first gear and the second gear to one another via the main shaft.
  • This main shaft does not run through the combing heads themselves, but in particular the main shaft runs past the combing heads and preferably only connects the two gears to one another.
  • a single gear can also be provided, from which two main shafts running out of phase with one another are led out, with the gear being arranged in particular between the two combing heads or groups of combing heads to be driven out of phase.
  • the main shafts then have an operative connection to one another, via which the first and second combing heads are coupled to one another.
  • the phase offset can be adjusted mechanically rigidly with particular advantage via the main shaft.
  • the main shaft can have an adjusting means for this purpose, through which a part of the main shaft connected to the first transmission is relative to one with the part of the main shaft connected to the second gear can be adjusted about a shaft axis.
  • the adjusting means can be on one or both gears, so that there is only one main part of the main shaft, which extends between the adjusting means and the main drive motor.
  • the adjusting means consequently makes it possible to set the phase offset, and the adjusting means can be equipped with actuators in order to change the phase offset, for example via a control unit of the combing machine, either when it is at a standstill or even during operation. If the adjusting means is designed in such a way that the phase shift can be adjusted via a control unit, in particular during operation of the combing machine, the phase shift can also be monitored via a control unit so that the power consumption of the combing machine remains minimal.
  • the first gear is arranged at a first end of the row of combing heads arranged side by side and that the second gear is arranged at a second, opposite end of the row of combing heads arranged side by side.
  • the first gear and the second gear enclose the entire unit of the combing heads between them, with the first group of combing heads from mutually adjacent combing heads having a left-hand part and the second group of combing heads from mutually adjacent combing heads having a right-hand part of the row of all combing heads arranged side by side in the machine frame.
  • the groups of combing heads operated with a phase offset are formed on two sides, and the row of combing heads forms a transverse axis of the machine frame, which forms the longitudinal extent of a combing machine in a manner known per se.
  • the two groups of the combing heads operated with a phase offset to one another thus form a left and a right part of the row, and the left part of the combing heads, for example four, is operated out of phase with a right part of the combing heads, also for example four .
  • the first group of combing heads has a common first drive input shaft that is operatively connected to the first gear
  • the second group of combing heads has a common second drive input shaft that is operatively connected to the second gear.
  • the combing heads each have a nipper shaft, it also being conceivable to design the nipper shaft of the first group of combing heads as a common nipper shaft, and the nipper shafts of the second group of combing heads can be designed as a further common nipper shaft.
  • the oscillating movement of the first tong shaft can run in the opposite direction to the oscillating movement of the second tong shaft.
  • the combing heads also each have a circular comb shaft, the circular comb shafts of the first group of combing heads being connected to form a common first circular comb shaft and the circular comb shafts of the second group of combing heads being connected to a common second circular comb shaft. Consequently, the circular comb shafts can also compensate one another, which may be coupled to the gripper shafts and to the shafts of the detaching cylinders, so that the coupling of the circular comb shafts can also be used to compensate for the operation of discontinuously operated cylinders of the respective group of combing heads.
  • the first gear and the second gear can either only drive the respective drive input shaft of the combing heads or the first and second gears are designed in such a way that they already drive the respective shafts of the combing heads individually in groups.
  • the first and the second gear have a prestressed toothing in order to enable a backlash-free load change.
  • a prestressed gearing of the gears enables an immediate change of torque without creating backlash.
  • the preloaded toothing can be done, for example, using the principle of a three-pinion clamping or the like.
  • phase offset between the nip clearances of the first group of combing heads and the second group of combing heads can be changed and adjusted as desired, and it is also conceivable that the phase offset is continuously adjusted or adjusted depending on a minimum power consumption as a reference variable during operation of the combing machine is readjusted, for example by measuring or monitoring the average power consumption.
  • the machine frame has a left cheek part and a right cheek part, the first gear being arranged in or on the left cheek part and the second gear being arranged in or on the right cheek part.
  • the first group of combing heads is thus located adjacent to the left cheek portion and the second group of combing heads is located adjacent to the right cheek portion.
  • no shafts or other transmission means extend between the left group and the right group of combing heads, and only the main shaft for coupling the two gears extends over the entire width of the machine frame and consequently also between the left cheek part and the right cheek part.
  • the drive input shaft, the nipper shaft and/or the circular comb shafts and/or other gear shafts of the combing heads of the first and second group are aligned with one another. It is also advantageously possible that the drive input shaft, the nipper shaft and/or the circular comb shafts and/or other gear shafts of the combing heads of the first group and the second group are offset from one another in their directions of extension. This results in only minimal vibrations, in particular balancing shafts can be provided, which are coupled, for example, with the parts of the main shaft between the first and the second gear so that only minimal or no torque arises about a longitudinal axis or a vertical axis of the combing machine.
