Definitions
- the invention relates to a method for separating from a fiber-waste mixture on a textile machine, in which the fiber-waste mixture is thrown off tangentially by a rotating roller and comprises an apparatus for carrying out the method.
- waste or the like In the area of spinning preparation, in particular when opening, cleaning and carding, and in subsequent processing steps, waste or the like must be separated and separated from fibers. This happens regularly in practice on rotating rollers in connection with rusting and. The like. A considerable part of the fibers is often separated with the waste. That is u. a. attributable to uncontrolled air flows. The accumulation of fibers in the waste represents a loss.
- the invention is therefore based on the object of providing a method of the type mentioned at the beginning, in which Waste is deposited with as few fibers as possible, so that the loss of fibers is largely reduced.
- the invention is based on the idea of using the different mass of the waste particles and the fibers to separate the two components. Due to the fact that an air stream acts on the fiber-waste mixture, the considerably lighter fibers are blown out of this mixture and preferably returned to the rotating roller; the waste, which may still contain a few fibers, is then suctioned off. Due to the larger mass, the waste parts have a higher kinetic energy, so that the waste parts in a z. B. counter-rotating fluid flow have a much longer braking distance than the fibers, which have a lower mass.
- the method according to the invention takes advantage of this process and thereby allows a safe separation between the waste parts and the fibers.
- the method according to the invention is used in particular with rotating, garnished rollers, e.g. B. cleaning rollers with impact lugs, licker, drum or the like. Applied to carry the waste parts and fibers in the direction of rotation. This is made possible by the outer covers of the rollers. In the case of one or more openings in the cover, the waste parts and the fibers endeavor to emerge tangentially from the opening at a certain angle at the opening point.
- the braking distances x crit p (braking distance waste part) and x crit f (braking distance fiber) can be calculated for certain speeds according to the following relationship:
- the air flow is expediently directed in the opposite direction onto the fiber / waste mixture.
- the air stream is preferably directed obliquely or approximately perpendicularly to the fiber-waste mixture, specifically in the direction of the roller, so that the fibers can be returned to the roller.
- An advantageous device for carrying out the method is characterized in that a braking duct is provided in the direction of the centrifugal force of the fiber-waste mixture, which leads into a waste collecting chamber which is connected to a suction device and that a compressed air duct connected to a compressed air source is provided, whose output is directed to the brake channel.
- the width of the brake duct is preferably adjustable in order to enable metering for the adjustment of the brake air flow. This setting is expediently locked.
- the length of the brake channel is preferably adjustable. This allows the braking distance to be varied so that the limit particle sizes still to be permitted for separation can be set on site. According to a further advantageous embodiment, the direction of the compressed air channel is adjustable.
- Figure 1 shows the drum 1 of a card, not shown.
- the drum 1 rotates counterclockwise (see arrow).
- the drum 1 is assigned a drum cover plate 2 which has an opening 3.
- the fiber-waste mixture is entrained by the drum and enters the brake channel 4 at the opening 3 in the direction of the centrifugal force.
- the brake channel 4 leads into a waste collection chamber 5 which is connected to a suction device (not shown).
- a compressed air channel 6 is provided which is connected via a compressed air connection 7 to a compressed air chamber 8 which is connected to a compressed air source (not shown).
- the outlet of the compressed air duct 6 is directed towards the inlet of the brake duct 4.
- an adjusting element 9 is provided, with which the width of the brake channel 4 can be adjusted. This adjustment element 9 can be locked.
- the fiber-waste mixture is entrained by the drum 1 and exits through the opening 3 in the drum cover plate 2 and into the brake channel 4.
- An air flow from the brake channel 6 acts obliquely on the fiber-waste mixture and blows the fibers back onto the drum.
- the waste parts fly due to their larger masses into the brake channel 4 and are removed via the waste collection chamber and the suction device.
- the length of the brake channel 4 is adjustable.
- the brake channel 4 is designed as a socket 41, over the end of which a pipe socket 42 is slipped.
- the end of the pipe socket 42 is slidably arranged on the end 41 and z. B. detectable by a locking device 10.
- the direction of the compressed air channel 6 is adjustable.
- the compressed air duct 6 consists of the wall 61, which is opposite a movable wall 62. This wall 62 can be varied depending on the particle exit angle and speed.
- FIG. 3 shows a diagram for calculating the braking distance of a particle by means of an opposing air flow.
- the initial particle speed is on the abscissa worn, while the coefficient n crit is plotted on the ordinate.
