Definitions

  • the present invention relates to a combing machine for spinning preparation with a machine frame in which several combing heads are arranged in a row 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, as well as a brush roller for cleaning the circular comb roller performs a continuous movement, resulting in a discontinuous power consumption for a main drive motor consisting of further, discontinuously rotating working cylinders with acceleration and deceleration phases over the comb play and these driving or receiving Waves 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 a Synchronous running of the combing heads is ensured.
  • 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 at an operating optimum in terms of speed and torque, since the output torque changes periodically and repeatedly over each backlash.
  • 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 combing machine should run quietly and with little vibration and oscillation during operation.
  • the invention provides that a first group of combing heads is operatively connected to the main drive motor by means of a first drive connection and can be driven in a first phase position, and that at least a second group of combing heads is operatively connected to the main drive motor by means of a second drive connection and in a second Phase position can be driven, wherein the combing heads that can be operated in the first phase position and the combing heads that can be operated in the second phase position alternately and/or from a middle of the row of combing heads are set up symmetrically to one another, so that during operation of the main drive motor the combing games of the combing heads of the first and at least second group run out of phase with one another.
  • 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 portion of the 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 interleaved phase shift during operation of the combing machine of the combing heads that are adjacent to one another allows the combing machine to run particularly smoothly during operation.
  • the first group of combing heads is interleaved with the second group of combing heads in such a way that adjacent combing heads have a total or predominantly phase shift relative to one another, so that the combing games of the adjacent combing heads are phase-shifted.
  • the two middle combing heads can, however, be operated in phase with regard to their comb play as an exception.
  • the phase offset can be set up alternately in the row of combing heads within the machine frame in a simple manner, whereby, as already mentioned above, there is also the possibility, with an even number of combing heads, which is usually present in a combing machine, from the symmetrical center to operate the combing heads alternately out of phase.
  • two combing heads set up laterally to the symmetrical center of the row of combing heads can run in phase, and each further adjacent combing head is operated out of phase.
  • phase positions of the comb clearances of the combing heads have to be present, and more than two phase positions can also be provided, which are set up in particular in relation to one another in such a way that dynamic forces during operation of the combing machine are compensated for in each case by a resulting symmetry, comparable to a reciprocating engine with a higher number of cylinders, which naturally runs more smoothly than a reciprocating engine with a lower number of cylinders.
  • eight to sixteen combing heads for example, one combing machine, each combing head can be operated out of phase with the other combing head. Or two combing heads are operated as a group phase-shifted to the other four to eight groups of combing heads.
  • the group of combing heads can consist of a single combing head, two or four combing heads in a combing machine with eight combing heads.
  • the group of combing heads can consist of a single combing head, two, four or eight combing heads, which are each operated out of phase with one another.
  • the drive connections between the main drive motor and the groups of combing heads can enable two different or more phase positions.
  • the drive connection to each individual combing head can be designed in different ways, and two options are shown below for setting up the drive connection between the groups of combing heads and the main drive motor.
  • a first possible embodiment of a drive connection is via a common control shaft and associated phase shifting means, and a second possible embodiment of a drive connection is shown using two rotating or oscillating drive shafts connecting the respective groups of combing heads to the drive motor.
