Definitions

  • the invention relates to a device for feeding and compacting a wadding web, comprising at least three calender rolls arranged one behind the other.
  • cotton wraps are produced in automatic winding machines in which the cotton wool is wound up on an empty sleeve between at least two calenders.
  • the calenders are driven by a one-sided spur toothing, wherein the calenders are guided and stored in a linear guide or alternatively via a leaf spring pendulum. Due to the varying distances between the calenders, especially when threading a new cotton wool beginning, there is the possibility that the gears do not mesh completely with each other. This leads to an undesirable noise level and increased wear of the transmission.
  • a winding machine in which the winding is produced in an endless belt.
  • an empty sleeve of the endless belt is wrapped around at least 270 ° and inserted between the sleeve and endless belt, the cotton wool.
  • the endless belt is guided by means of calender rolls, which are mounted on guide elements on the machine frame.
  • calender rolls which are mounted on guide elements on the machine frame.
  • a one-sided Add component from the resultant of the belt forces In this one-sided belt drive comes on the calendering force a one-sided Add component from the resultant of the belt forces. This can lead to uneven cotton wool.
  • the device comprises at least three calender rolls arranged one behind the other as well as a drive which drives by means of a belt in each case one of the calender rollers associated pulley.
  • a flexible drive element is arranged between each pulley and the associated calender roll.
  • no unwanted force component acts due to a common direct belt drive on the calender rolls, which has a positive effect on the quality of the cotton web.
  • the drive with the pulleys remain stationary on the housing remain.
  • the compensation is created via the flexible drive elements.
  • an unacceptably high noise due to each other corresponding drive elements and the associated wear is avoided.
  • a flexible drive element is arranged between two pulleys and the associated calender rolls. It may be enough, two To provide calender rolls with a flexible drive element.
  • the third calender roll is directly driven by the belt which is connected to the drive, that is without an intermediate flexible drive element.
  • the belt can be guided with the deflection rollers so that no undesired forces acting on this calender roll. Since the two other calender rolls are driven by an interposed separate flexible drive element, all three calender rolls can nevertheless be adjusted at a distance from each other, without this having any effect on the drive.
  • flexible drive elements for example, belts, chains, drive shafts and flexible couplings are considered.
  • the flexible drive element is designed as a belt drive.
  • the calender rolls can be adjusted at a distance to each other, without this having a significant impact on the drive power.
  • the belt drive comprises a belt, a pulley disposed on the calender roll, and a pulley rotatably connected to the pulleys.
  • the belt drive may be advantageous for the circulating belt for the calenders to be arranged on an operating side of the device, and for the drive to be arranged on a drive side of the device. This can be used to create a very compact calender.
  • the flexible drive element may be formed as a propeller shaft.
  • These have the advantage that a large axial or angular offset can be compensated without this having a significant influence on the drive power.
  • the design of the flexible drive element as a parallel crank clutch has the advantage that in a small space, the pulleys can be connected to the drive. This embodiment can compensate for an axial or angular offset.
  • Figure 1 a first embodiment in perspective view of the calender from the drive side
  • FIG. 2 shows a perspective view of the calender from FIG. 1 from the operating side;
  • Figure 3 a side view of the calender after the first
  • Figure 4 a second embodiment of the calender.
  • FIG 1 three calender rolls K1, K2, K3 are shown, which are arranged in the running direction of the cotton web in front of the winding calenders, not shown, and have the task of compressing or compressing the cotton web.
  • the calender rolls K1-K3 are arranged essentially one behind the other in a row and each have an exhaust A1, A2, A3, with which loose fibers and dirt are sucked.
  • the distance or gap between the calender roll K1 - K3 and the associated suction A1 - A3 is by one Tensioning device S1 - S3 adjustable, whereby the threading of the cotton web can be facilitated.
  • the calender rolls K1-K3 adjustable at a distance from one another.
  • more than three calender rolls can be arranged in a calender, if necessary.
  • the cotton web is introduced into the calender 1 from below between the calender rolls K2 and K3. After the wadding has wrapped the calender roll K2 by 180 °, it is introduced below the calender roll K1 in the winding machine.
  • an unillustrated motor drives a belt 4 via a drive pinion 5.
  • the belt 4 may be formed as a flat or toothed belt, wherein in this embodiment, a toothed belt is used.
  • a deflection pinion 6 ensures the necessary wrapping of the belt 4 on the drive pinion 5 and a tensioning pinion 7 with a tensioning device 7a for the necessary tension of the belt 4.
  • the belt 4 in turn drives a pulley 8, which is arranged on a shaft 9.
  • the shaft 9 transmits the torque of the pulley 8 from the drive side 2 on the operating side 3 to a second pulley 11.
  • the pulley 11 in turn drives another belt 10, which is formed as a flat belt.
  • the belt 10 at least partially wraps around three pulleys R1, R2 and R3 associated with the respective calender rolls K1-K3.
  • the pulleys R2 - R3 are not connected to the calender rolls K2 - K3, but stored separately from these on the frame 13 and fixed. Only the pulley R1 is rotatably mounted in this embodiment on the axis of the calender roll K1. But it can also, as the pulleys R2 and R3, be arranged on the frame 13 of the calender 1.
  • the belt 10 is deflected by one or more deflection rollers 12, which are also arranged on the frame 13 and with which the required wrap angle is generated at the pulleys R1 - R3.
  • a separate flexible drive element in each case transmits the driving force from the belt 10 to the calender rolls K2 and K3.
  • the separate flexible drive element is formed according to the figures 1 to 3 as a belt drive, wherein the calender rolls K2 and K3 each have a arranged on the operating side 3 pulley 14b, 14c, which are connected via a separate belt 16b, 16c with a pulley 15b, 15c , which is rotatably mounted on the pulleys R2 and R3.
  • the flexible drive element comprises in this embodiment, therefore, a belt 16b, 16c, arranged on the calender roller pulley 14b, 14c, as well as with the pulleys R2 and R3 rotatably connected pulley 15b, 15c.
  • the belt 10 drives only the calender roll K1 directly.
  • the torque of the belt 10 on the calender roll K2 is transmitted via the belt 16b and the pulleys 14b and 15b.
  • the belt 10 provides the common drive power of the calender rolls K1-K3, no undesirable force resulting from the drive force acts on the wadding web due to the interposed separate flexible drive elements on the calender rolls K2-K3.
  • the separate flexible drive elements allow a targeted determination of the force resulting on the calender rolls K2 - K3.
  • the calender rolls K1 to K3 are driven on the drive side 2, a belt 10 being driven by a drive 18 by means of a pulley 19.
  • the belt 10 in turn drives the pulleys R1 to R3, which are respectively associated with the calender rolls K1 to K3.
  • the belt 10 which may be formed as a flat or toothed belt, thus runs simultaneously on the pulleys R1, R2, R3 and 19.
  • a drive chain can be used.
  • the suitable is to compensate for a sufficiently large misalignment.
  • the flexible drive element is designed as a hinge shaft 17a, 17b, 17c, for example as a universal joint shaft or cardan shaft. This can be compensated for high torque, a large axial offset or a large angular offset while length compensation. If a shorter distance between the calender rolls K1 to K3 and the drive 18 to be realized, can be used as a flexible drive element instead of the propeller shafts 17a to 17c as a further alternative, a parallel crank clutch. The space between the drive 18 and the calender rolls K1 to K3 can thus be significantly reduced. Also by this embodiment of a flexible drive element no additional force acts on the wadding path.
  • each calender K1-K3 can be driven by its own drive, for example a direct drive, servo drive or a hub motor, whereby the calenders K1-K3 can be adjusted and driven completely independently of each other.
  • a suitable controller can then link the drives electronically, so that, for example, a delay can be set between the calenders.
