Definitions

  • the invention relates to a device and a method for preparing and feeding cleaned textile fibers in an associated textile processing machine, an air flow conveying fibers directly into a vertical feed shaft by a cleaning device that works with an increased cleaning effect.
  • This type of vertical feed shaft usually has a storage container called a reserve shaft, which is arranged above the shaft area.
  • the fibers are guided horizontally into the reserve shaft by an air flow carrying the fibers.
  • the air exits the reserve shaft, causing the fibers to be deposited in a column above an upper feed roller that feeds the fibers into the shaft area.
  • the fibers are typically cleaned by a flake feeder such as that described, for example, in US Pat. No. 4,682,388 and introduced into the air stream. Then the fibers are fed from the flake feed device to the vertical feed shaft.
  • the flake feed device has a pair of feed rollers which form a clamping point and between which the fibers are transported on a feed belt which feeds the fibers into the transport air flow to the reserve shaft of the feed shaft.
  • the amount of fibers that are fed to the reserve shaft is determined by determining the air pressure in the feed channel leading to the reserve area. When fibers accumulate in the spare shaft, the air pressure increases. This is because an air outlet arranged on a wall of the reserve shaft is blocked less or more with fibers, so that the air pressure changes accordingly.
  • Such a feed and control system is in U.S. Patent 4,682,388. The change in air pressure is used to determine the amount of fiber and to control the feed rollers of the flake feed device so that the fiber feed can be controlled accordingly.
  • the feed rollers of the cleaning device create a feed with a clamping point, in which the fiber feed can be actively stopped and started without any time delay, ie feeding or stopping the feeding of fibers takes place practically instantaneously.
  • the fiber feed is also stopped, so that the controlled fill level in the reserve shaft remains relatively the same and in the desired range.
  • Such a filling level is normally desired so that part of the air outlet remains free. The escape of air is necessary to prevent the fiber column in the reserve shaft from being subjected to excessive pressure and to prevent the feed roller from being overloaded and blocked.
  • Fiber cleaning machines which have no nip point and in which the fibers are only guided by a flowing air stream over fiber cleaning and opening rollers.
  • a fiber cleaning device without a pinch point is manufactured by Hergeth Hollingsworth GmbH in Dülmen, Federal Republic of Germany, under the name roller cleaner model WR / Z.
  • This roller cleaning device is particularly suitable for cleaning various types of heavily contaminated cotton and is mainly used as an initial cleaning device in a cleaning line.
  • Such fiber cleaning devices without clamping points are usually arranged between a bale opening machine and the mixing station within a cleaning line. With this type of cleaner, the cleaning effect and opening properties are excellent.
  • the fibrous material is passed axially through a pair of rollers and exits the other side of the cleaning machine, being contained in the transport air stream all the time.
  • this fiber cleaning device there is generally no feed with a clamping point which can control or prevent excessive fiber accumulation in the reserve shaft if it is necessary to stop the feeding process.
  • Excess fibers that are carried in the pipelines are deposited in the reserve shaft with this device, as a result of which the feed roller at the nip point can be blocked by overloading. Since, according to the prevailing opinion, vertical feed shafts have to be fed by cleaning devices which have feed with a clamping point, no cleaning point-free cleaning devices have been used to feed vertical feed shafts.
  • a further object of the invention is to provide a method for cleaning fibers and for supplying cleaned fibers to a vertical feed shaft, in which a pinch-point-free fiber cleaning device working with an increased cleaning effect is used.
  • the invention is intended to provide a system and a method in which cleaned fibers can be fed to a vertical feed shaft by means of a pinch-free fiber cleaning device without excess fibers containing in the continuous air stream being deposited in the feed shaft if there is no material requirement for the feed shaft.
  • the invention is also intended to provide a system and method in which the fibers are fed directly from a pinchless fiber cleaning device to a vertical feed shaft, the control of the system being such as to compensate for excess fibers contained in the air flow passing therethrough when one processing machine fed through the feed shaft, e.g. Card or the like is stopped so that the like when resuming the carding process. blocking of the shaft feed roller is prevented.
  • one processing machine fed through the feed shaft e.g. Card or the like
  • a preferred embodiment of this textile fiber preparation and delivery system is provided with an air flow channel which is a fiber source with an inlet to the cleaning device and connects an outlet from the cleaning device to a reserve shaft, a control device which controls a quantity of fibers fed from a fiber source as a function of the quantity of fibers in a reserve shaft; wherein a controller controls the operation of an upper feed roller in response to a fiber level in an effective zone for forming a fiber mat, and wherein the control device continues to operate the upper feed roller after delivery of a fiber mat is completed to remove excess fibers that have deposited in an airflow channel , which extends from the fiber source to the reserve shaft, and to prevent blocking of an air outlet of the reserve shaft, so that when the fiber mat delivery is resumed, the upper feed roller is prevented from blocking.
  • Figure 1 is a schematic representation of the textile fiber preparation and feeding system with the pinchless fiber cleaning device.
  • A denotes a mixing plant for the production of a fiber mixture.
  • the fibers are transported in the form of an air stream 10 carrying fibers from the mixing device to a fiber cleaning device B without a pinch point.
  • the fibers are transported in the air stream through the cleaning device B directly to a vertical feed shaft C without a nip point.
  • the fibers are compressed in the vertical shaft and in the form of a Compact fiber mat 12 issued or the like an associated card. 14 is supplied.
  • Mixing system A effects an effective niche at this stage of fiber processing.
  • Mixing is one of the first processes in fiber preparation and is used to homogenize and intensify fiber flake mixtures, to compensate for deviations in material density and to compensate for differences in material moisture.
  • the fibers can be fed to the mixing device by a conventional or an automatic bale opening system, as is described, for example, in DE-3 208 346 (US-4 514 881).
  • the fibers pass from the fiber bale opener system through an inlet 16 into the mixing device. 16 is the inlet to a reciprocating fiber-air separator 18 which is conventionally moved perpendicular to the direction in which the fibers travel through the mixer.
  • the transverse movement of the separating device distributes the separated fibers evenly in layers over the entire working width of the mixing device.
  • the density of the fibers in a mixing chamber 20 of the mixing device can be precisely controlled in a conventional manner by means of photocells and a pressure roller (not shown).
  • the fiber layers are transported on a conveyor belt 22 in the mixing device and fed to a needle-punched cloth 24, which removes the fibers from the cross-section of the layers and further transports them to a stripping roller 26, from which the fibers are fed to the cleaning device B by the transport air stream 10.
  • This mixing device is a processing machine for natural and man-made fibers with a stack length of up to 120 mm.
  • the pinch-free fiber cleaning device B is arranged between the mixing device or another fiber source and the vertical feed shaft C.
  • the cleaning device B has an inlet 30 on one side and an outlet 32 on the opposite side. Any suitable fiber cleaning device without a clamping point when the fibers are conveyed through the cleaning device can be used.
  • the cleaning device is provided with a pair of opening and cleaning rollers 34 and 36. The fibers are moved axially along the length of the rollers rotating at high speed by the transport air stream 10. Contaminants separated from the opening rollers fall through a grate 38 into a floor container of the cleaning device, from which they can be removed by suction. The rolls rotate continuously while the fibers are transported along the opening rolls.
  • the opener rollers 34 and 36 are provided with pins 40 which extend radially outward.
  • a transport fan 42 creates the air flow to carry the fibers.
  • the transport air stream 10a which emerges from the cleaning device B, contains opened and highly cleaned fibers.
  • the air stream 10a with the cleaned fibers enters an inlet duct 44 of the vertical feed shaft.
  • the vertical feed shaft C is provided with a reserve shaft 46 which receives the fibers, the air from the transport air flow in the direction of arrows 48 exits through an air outlet 50 which is formed in a rear wall of the reserve shaft 46.
  • the air outlet 50 may have a reed plate through which the air exits.
  • the fibers are deposited in the reserve shaft F over an upper feed roller 52.
  • the upper feed roller 52 introduces the fibers into an active zone 54 to form a fiber column, which leave the fibers in the form of a compressed fiber mat 12.
  • the fiber mat is removed by delivery rollers 56.
  • the operation of the feeder shaft is conventional and is described in detail, for example, in US 4,476,611.
  • the card or the like. 14 can sometimes be switched off for various reasons, which can even happen several times in a day.
  • the pinch-free fiber cleaning device B causes an increased throughput line and an increased cleaning effect, but also produces an excessive amount of fibers in the channel system 58 between the fiber source at the mixing device A and the upper feed roller 52 of the vertical feed shaft C.
  • a control system 60 regulates the amount of fiber that does that Reserve shaft 46 is supplied. This is done by determining the pressure with a pressure sensor 62 which indicates the amount of fiber present in the reserve shaft. When fibers accumulate and more or less cover the air outlet 50, the pressure changes so that it gives an indication of the amount of fibers.
