Definitions
- the invention relates to sliver separation in a spinning preparation machine, in particular a draw frame. This represents a preceding processing stage in the thread production process, in which any defined, tangled fiber composite creates a defined fiber parallelizing fiber sliver, which is separated into defined, limited lengths for the process transport.
- a belt end hanging from the storage package of a spinning can trigger the uncontrolled falling of further stored belt lengths.
- the aim of the invention is to minimize the maintenance effort and the susceptibility to faults of the band separation elements and to carry out the band separation in a manner that is gentle on the material, without removing fiber parts from the band and without loss of band.
- the task is to realize the band separation without high expenditure on machine technology and to be able to react variably to the requirements of different types of sliver.
- the sliver separation takes place using existing machine technology in the closed cross-section of the sliver guide channel by a difference in delivery speed between
- the nip line spacing of these roller pairs is larger than the longest individual fibers of the sliver.
- the sliver guide channel is separated by overcoming the internal adhesive force of the sliver, with no single fiber being damaged.
- the separated sliver end is deposited cyclically in the spinning can by the delivery slewing gear without the sliver end hanging over the edge of the spinning cannula.
- the sliver end remaining in the sliver guide channel is transported to the calender rolls with the help of the blowing nozzles present on this to continue the working process. If, on the other hand, the output rollers perform a lower delivery speed than the calender rollers of the delivery slewing gear, a thin point of the fiber ribbon is created in the fiber ribbon guide channel. This formation of dusters is supported by an arch in the sliver channel.
- the separation of the sliver within the depositing member of the delivery rotating mechanism is achieved by means of a relative movement of the sliver can by overcoming the internal adhesive force of the sliver, the sliver end remaining in the depositing member.
- the separated sliver end is cyclically deposited in the spinning can. This separation process is controlled by a microcomputer.
- Conveyor unit of the delivery slewing gear 3 leads.
- a blowing nozzle 7 At the beginning of the band channel 8 there is a blowing nozzle 7.
- a second blowing nozzle 9 At the output end of the band channel, a second blowing nozzle 9 is arranged in a fixed position above the pair of calender rolls 10, which at the same time has the function of a fiber band compressor element.
- the output rollers 5 and the pair of rollers 6 can be separated from the overall drive with a clutch.
- the entire machine is stopped.
- the clutch then comes into operation, so that the drive can only act on the calender rolls 10 and the delivery slewing gear 3.
- the drive then comes into operation.
- the clamping lines of the stationary output rollers 6 hold the sliver 1 in place.
- the ongoing calender rolls 10 now exert a tensile force on the sliver 1 in the longitudinal direction.
- This process can be varied in time using the microcomputer and can be set to different types of sliver.
- the blower nozzle 7 transports through its compressed air flow the remaining machine-side sliver end in the belt guide channel 8 when the machine is restarted up to the stationary calender rolls 10.
- the blower nozzle 9 arranged above supports the introduction of the sliver 1 into the clamping line of the calender rolls 10 and simultaneously compresses it.
- blow nozzles 7 and 9 are switched off and the machine runs until the next separation process.
- the drive of the output rollers 5 and 6 is not stopped completely, but only runs more slowly than that of the calender rollers 10.
- the application described at the outset runs with the difference that a thin net is produced in the sliver 1, which only completely breaks off at the depositing member of the delivery rotating mechanism 3.
- the sliver end on the machine side for the restart of the machine is already present in the clamping line of the stationary pair of calender rolls 10.
- Nozzles 7 and 9 only have a supporting transport function when the machine is restarted.
