Definitions

  • the invention relates to a device for treating a Flow of fiber material in a fiber processing plant according to Preamble of claim 1.
  • Such devices are especially in spinning preparation, in the so-called Blow room, well known and in use for a long time. In doing so Cotton fibers from the delivered cotton bale to one cleaned and ordered fleece processed.
  • the different Blowroom machines form individual treatment modules, which are linked together to form a processing line will.
  • DE-A-195 16 568 is a genre comparable Apparatus known, in which several treatment modules are arranged in series. After a bale opener as the first treatment module follows as second treatment module a device for recognizing and Elimination of foreign substances. According to Frey Manfred "recognition and excretion of foreign substances in the blow room ", mittex 1/1995, pages 12 to 15, is a device for recognition and excreting foreign matter after a fiber mixer arranged.
  • a disadvantage of the known devices is that each device for recognizing and eliminating Foreign material integrated into the system as a separate unit is. This requires and requires complex transport lines a lot of space. Depending on which sensor system is used , it is also necessary that the fibers or Flakes presented to the sensor in a certain form so that a high degree of efficiency in foreign material separation can be reached.
  • An input side Feed device is usually to guarantee a regular flake flow is provided.
  • most blow room machines have on the output side any device with an opening function. The multiple Use of opening devices and feeding devices however, obviously increases the cost of the whole Investment.
  • This object is achieved according to the invention solved with a device that features in claim 1.
  • the output-side opening device on the first treatment module thus fulfills a double function by simultaneously as a feed device of the second treatment module serves.
  • a separate opening device to loosen up the Fibers for their presentation on the sensor field are no longer required.
  • the two treatment modules can also be coupled together in such a way that no fiber transport line between the two modules is required. In order to the space requirement for the entire system decreases and it becomes Pipelines saved.
  • dissolving device Basically all means come in as a dissolving device Consider that have a resolving function and that to one Enlargement of the entire fiber volume. It can with the opening device around a classic opening roller or cleaning roller that interacts with a knife grate. Also a removal roller for the removal of the Flow of fiber material from an upstream means of transport comes into consideration as a dissolving device. Depending on the type of Detection of foreign matter can be the degree of resolution through the use of individual dissolving agents or through their Combination can be determined.
  • the first treatment module is advantageously a fiber mixing device, so that subsequently in the second Treatment module the mixed fibers on foreign material can be checked.
  • the first treatment module it can is already a bale opener or one Trade mixed bale openers for cotton bales. But also one Fiber cleaning device comes as the first treatment module in which the fibers of vegetable contaminants, Sand, dust and the like are freed.
  • the first treatment module can be a conveyor belt, in particular have a needle slant that is steeply inclined to the horizontal, the opening device at the end of the conveyor line is arranged.
  • a lattice is on Mixing machines or mixing bale openers for the removal of the compact fiber mass common and at the end of the conveyor line Means must be provided to dissolve the Fibers such as a take-off roller, a stripping roller and / or an opening roller.
  • the resolving device is preferably above the sensor field arranged, the fiber material flow at least partially can be fed to the sensor field under the influence of gravity. Of the at least partially free fall leads to a calming and Even distribution of the fibers before they reach the sensor field happen.
  • the flow of fiber material can at the disintegration device but also be accelerated, at least he partly under the acceleration effect of the sensor field is feedable.
  • the Acceleration e.g. by centrifugal forces on the rollers, with the fibers thrown off the roll surface will.
  • the relative position between the resolver and the trajectory of the fibers is the sensor field as possible optimally adapt.
  • means for Blowing of conveying air can be arranged, the fiber material flow in a continuous air flow to the sensor field is feedable.
  • the Velocity of the fiber material flow according to the parameters of the sensor system and the response time of the separation device can be customized.
  • the different Means for supplying the stream of fiber material to the Sensor field can also be used cumulatively. So that can can be achieved with different density materials pass the sensor field at the same conveying speed.
  • the fiber material flow is preferably downwards in a transport shaft can be fed to the sensor field by the resolver, which is arranged vertically or the maximum 45 ° to Vertical is inclined.
  • the transport shaft is preferably in this case detachably arranged so that to adapt to the relative position the opening device transport shafts with different Inclination are mountable. That way the second treatment module to different first treatment modules be connected, to adapt to the respective dissolving device of the first treatment module only the transport shaft needs to be replaced.
  • the separation device in the second treatment module can a diverter flap for the separation of foreign material due to mechanical deflection. About such flaps can also be relatively heavy foreign parts, such as. Eliminate stones, metal parts, etc. reliably.
  • the separating device can also at least a blow nozzle arrangement for the excretion of Have foreign material from a pressure surge. That kind of Elimination is suitable e.g. to excrete fibrous Materials such as Cords, discolored fiber material and the like. Basically, a suction of foreign material would also be conceivable with at least one suction nozzle unit. At several, side by side nozzle units is also selective separation across the entire width of the fiber material flow possible.
  • the separation device can be metered of conveying air arranged in a subsequent fiber transport line be.
  • the device shown in Figure 1 consists of a first treatment module 1 and from an output side connected second treatment module 2.
  • the device is part of a blow molding plant in a Spinning, whereby other blow molding machines, e.g. a Bale removal machine upstream or one or more Cleaning or carding machines are downstream.
  • the first treatment module 1 is designed as a mixing machine, in which a homogeneous mixture of the processed Fiber material takes place. For this purpose, several are placed side by side arranged vertical storage chambers 9 over a Fibrous material inlet 11 filled where a mechanical and pneumatic Compression takes place. At the lower openings of the Storage chambers the material columns are deflected by 90 ° and stacked on a feed belt 10 in the direction of the arrow a transported. Due to the large difference in The individual material packages are the distance to be covered strongly shifted against each other. Subsequently the fibers from the compressed fiber package with a Needle lattice 8 removed and transported upwards. This principle of fiber mixing is known to the person skilled in the art known.
  • the removed and dissolved fiber material In contrast to known devices, the removed and dissolved fiber material, however, not within the first treatment module in a pneumatic conveyor line for further transport to the downstream blow room machine fed.
  • the end opening device 3 is rather trained and arranged so that they simultaneously the Function of a feed device for the immediate connected second treatment module 2 forms.
  • a stripping roller 7 At the Dissolving device 3, a stripping roller 7 is arranged, with what excess fiber material from the needle sling is removed and thrown back.
  • the actual fiber resolution takes place in conjunction with a take-off roller 6, the turns counterclockwise in relation to the illustration and which is provided with needles or bolts and the fiber material decreases evenly from the needle sling and flings away.
  • the take-off roller 6 protrudes over the end face of the first treatment module 1, but this is fixed assigned.
  • the flow of fiber material is at a sensor field 4 passed and any foreign substances determined are excreted on a separator 5.
  • sensor field and Elimination device can be designed very differently.
  • the sensor field is on both sides a transparent presentation shaft 14 arranged. As Sensors serve CCD cameras 15, 15 ', their optical axes via deflection mirrors 16, 16 'onto the presentation shaft 14 are directed. The flow of fiber is via lighting 17, 17 'illuminated.
  • the supply of the fiber material flow from the resolver 3 to the sensor field 4 or in the Presentation shaft 14 takes place via a transport shaft 21, which is at an angle of less than 45 ° to the vertical is arranged and against the presentation shaft 14th slightly rejuvenated.
  • the transport shaft is a separate component trained and at a flange-like junction 32 connected to the presentation slot. This makes possible the connection of different transport shafts each after arranging the opening device 3.
  • a feed air supply 12 is provided, via which a fan 13 Conveying air can be fed.
  • the supply air feed could also between the needle bar cloth 8 and the take-off roller 6 or at both locations. It would also be conceivable to achieve an air flow with the take-off roller 6 by this is equipped with fan blades.
  • the separating device 5 under the presentation shaft 14 has a diverter flap 19 with a pneumatic drive 18 can be deflected such that the fiber material flow temporarily into a waste bin on the side 20 can be redirected.
  • the pneumatic drive 18 receives via a control device, not shown here a control pulse as soon as the cameras 15, 15 'one Detect foreign matter.
  • the fibers on the dissolving device 3 become the presentation shaft under the influence of various forces 14 fed.
  • the fibers are subject due to the height difference of normal gravity.
  • the fibers are also affected by centrifugal forces hurled at the take-off roller 6 in the transport shaft 21 and get there under the influence of the continuous Air flow of the conveying air feed 12.
  • the treatment modules not side by side, but one above the other arranged.
  • the first treatment module 1 is a cleaning machine trained, their basic functioning is also known per se. In the cleaning machine only fine particles such as vegetable Impurities, sand, dust, etc. excreted, however no foreign matter with more compact or fibrous structures. Fibers are fed via a fiber material inlet 11 by means of a Feed roller pairs 24 continuously a cleaning roller 25 fed, which is provided with nasal discs and with a fixed knife grate arranged on a peripheral portion 26 interacts. Impurities are over a Outlet line 29 suctioned off.
