Definitions

  • the invention relates to a device and a method for discharging and Collecting those arising during the processing of a textile machine Waste material (e.g. fibers, shell parts, dust, etc.) according to the generic term of claim 1 or the preamble of method claim 21.
  • Waste material e.g. fibers, shell parts, dust, etc.
  • This fiber layer is then assigned by a suitable location Extracted suction channel and via a transport channel to a Departure collection station funded.
  • the outgoing collection station can also from a bag made of air-permeable material, which is the effect of a filter and can be replaced when filled.
  • the means that the present solution includes an isolated solution for waste disposal for a single combing machine.
  • JP-AS-3-33 805 is a system with a large number of combing machines can be seen, the exit (noils, dust, nits, etc.) over a central suction system is made.
  • the individual combing machines suction devices for the waste material to be discharged are assigned, which can be connected to a common discharge line via switching valves. This main line leads to several via a main valve Collection facilities.
  • In the suction device shown on the Combing machine is probably a kind of buffer.
  • the system is switched so that the output from the combers Disposal material by material type in the corresponding main store can be supplied. That means for the removal of the material to one certain material stores are consequently only the valves on the Combing machines opened one after the other, which are of the same material to process.
  • the manifold Before combing with another type of material the manifold is drained over a specified period of time and then the main valve is switched to the other total storage. With This facility is intended to prevent the waste material of the Combing machines of different material templates is mixed together. Since the combs of the waste material also become textile goods can be processed further is a sorting of these noils in relation on the finishing process necessary.
  • About the type and the execution of the buffer on the combing machine indicated here is here nothing specified. It can only be seen from FIG. 3 that the buffer from a extending along the combing machine There is a shaft at which a suction pipe opens in the middle, via a valve is connected to the common delivery line.
  • the levy of the Drum 1 in the buffer B can be according to the Embodiment take place according to CH-PS 503 126. From the cross section of the buffer and its longitudinal extent can be seen that it has a very large volume. This means that when you open the Valve C a large amount of air must be moved to the in the memory B Vacuum accumulated waste (noils). On the one hand, this requires one high suction power and probably leads to an uncontrolled air flow within the cache.
  • Means can be provided in the area of the air-permeable section which prevent air from entering the storage space through this zone when a negative pressure is applied in the storage space.
  • These means can preferably consist of an air-impermeable cover sheet attached to the periphery of the storage jacket on one side. On the one hand, this enables the cover sheet to be flexibly evaded when the storage tank is being filled, whereby the transport air that is carried diffuses outward through the air-permeable area and, on the other hand, the system on the storage jacket for covering and thus preventing the supply of ambient air (external air) during the emptying process if there is a negative pressure in the Memory is built.
  • the cover sheet can be made of plasticized fabric.
  • a plurality of cover sheets are preferably fastened side by side in the manner of a skirt on the circumference of the store. This creates a completely closed partition when an underpressure is created in the accumulator.
  • the longitudinal axis of the store is preferably oriented vertically and the free ends of the cover sheets point downward.
  • a device is proposed in which the air-permeable section begins at a distance x - seen in the longitudinal direction of the store - following the inlet opening, the distance x being in a range between zero and the measure of 1/3 of the total length of the store .
  • the air-permeable section is between the inlet and the Outlet opening arranged and allows good air discharge during the filling process. This means that the buffer can be filled optimally.
  • the area of the air-permeable section can be between 10 and 60% of the Amount surface of the memory. There are also design variants possible, but the air-permeable surface is not necessarily in one piece must be trained.
  • the length of the air-permeable section less than Is 60% of the total length of the memory.
  • the air-permeable section is preferably formed from a filter cloth.
  • the memory in the area Outlet opening is provided with a conical section, which is in Tapered towards the outlet end and a connection for an exhaust pipe forms.
  • the cross section of the memory is preferably circular.
  • the diameter ratio between the Diameter of the storage and the suction pipe between 3: 1 and 1: 1 can be. It must be chosen so that the emptying of the Memory can be done.
  • the memory in the Area of the outlet opening with at least one air-permeable zone is provided, which is arranged at a distance from the inlet opening, which is arranged at a distance from the inlet opening that is greater than 2/3 of the Total length of the memory is.

  • the air-permeable section is preferably made of one Filter cloth formed.
  • the Inlet opening opens into the circumference of the storage jacket.
  • the inlet opening in the axial direction of the Memory opens into the memory.
  • the proposed devices make it possible to carry out a claimed method, the separated waste material being fed to an intermediate store and then being transferred in stages to a common collection point. Further advantages and features are shown and described using an exemplary embodiment described below.
  • a combing machine K1 is shown in FIG. 1, which has eight combing heads 2 is provided. For each combing head 2, a cotton roll 3 is placed, which is for the Combing unrolled and a pliers unit, not shown Combing is fed. Such a pliers unit and the means for Combing the cotton wool or pulling off the combed cotton wool end shown and described in EP-A1-564 408. It will therefore not get any closer here dealt with it.
  • Example combs pass through schematically illustrated suction shafts 5 in a manifold 6.
  • a fan 8 which drives the motor 9, the deposited material in a conical filter part 10 a Waste separator 11 transferred.
  • the filter part 10 is air-permeable Knitwear formed, whereby the waste material (noils) from most of the transport air (90%) is separated. This severed Transport air (90%) can enter the ambient air through an outlet part 12 Spinning mill to be given.
  • the outlet part 12 is additionally with a Provide an air filter to retain the dust particles that pass through the filter 10 have penetrated.
  • this outlet part 12 it is also possible to connect this outlet part 12 to a central filter system connect in which the residual dust contained in the air mixture is separated before this air is returned to the environment.
  • the conical filter part 10 is at its tapered end with an outlet pipe 14 provided, which the leaving material with about 10% of the remaining Transport air supplies a tubular buffer 15.
  • the vertical arrangement of the filter part 10 in connection with a flexible filter cloth, the filter part is essentially self-cleaning.
  • the inlet opening 16 of the outlet pipe 14 opens in the example shown approximately in the middle of the intermediate storage 15 in its peripheral jacket 17. This can in particular also be taken from FIG. 2, the Buffer is shown enlarged. Is below the inlet opening 16 the intermediate store 15 is provided with an air-permeable screen jacket 19, which extends downward approximately at the height of the inlet opening.
  • the sieve jacket 19 can be formed from an air-permeable filter cloth. The length L1 of the screen jacket 19 extends over less than the total length L of Buffer 15.
  • the screen surface of the screen jacket 19 does not consist of a closed screen surface, but of several Individual screen surfaces, which are arranged accordingly on the circumference of the store are.
  • Tube 23 is attached to a pivotable flap 24, which over a Adjustment element 25 can be moved into the "open” or “closed” position. In the illustration shown, the flap 24 is in the "closed” position, that means that the discharge from the intermediate storage 15 is blocked.
  • the adjusting element 25 can be, for example, a pneumatically operated one Cylinder or an electric motor exist.
  • the outlet opening 22 is on tapered end of a conical part 27, which on the cylindrical Part 28 of the buffer 15 connects. At the end of the cylindrical part 28 before the transition into the conical part 27 can be distributed around the circumference Bypass openings 30 may be provided.
  • the bypass openings are in front of the Transition arranged in the conical part 27. It can be a or several bypass openings.
  • the individual bypass opening 30 is with an air-permeable filter 31 (e.g. a filter cloth), which the Passage of air, but not the passage of parts of the waste material A enables.
  • an air-permeable filter 31 e.g. a filter cloth
  • a flexible cover 32 is attached to the area of the bypass openings 30, which is pivotally attached at least on one side and with complete installation the outer jacket 17 (as shown) covers the bypass opening. In this situation prevents ambient air from being sucked off via the pipe 23 can be sucked through the bypass openings 30.
  • the dashed drawn position of the flexible cover then arises when over the Outlet pipe 14 of the intermediate store 15 is filled when the flap 24 is closed becomes. Since a during the filling process against the closed flap 24 Overpressure in room R above the outgoing material builds up to the ambient air, the flexible cover 32 is after pressed outside. On the one hand, this can cause the overpressure in room R dismantle and on the other hand allows the complete filling of the Buffer 15.
  • the conical jacket 27 leads to an increase in the transport speed the transport air during the suction process up to the outlet opening 22.
  • the pipe 23 opens into a collecting pipe 35, in which further disposal pipes from other combing machines or textile machines open.
  • a blower 36 which is the waste material feeds a fiber comparator 37.
  • the fiber comparator 37 there is another Separation between the transport air and the carried waste carried out.
  • the waste material essentially consists of short fibers, or noils, in compressed form from the fiber separator 27 are given down into a suitable container 38. That so Collected fiber goods can be packed for the purpose of further transport to subsequent processing stages for this fiber material.
  • this fiber material (noils) directly and without packaging in the same spinning plant fed to a suitable processing process becomes.
  • a diameter ratio B / D is also possible (depending on the material) than 2: 1 (e.g. 3: 1). This is to prevent, in particular, Area of the cone part 27 comes to blockages.
  • the longitudinal extent L1 of the screen jacket 19 accounts for less than 60% of the total length L of the buffer.
  • the Blower 8 transports the waste material delivered through the collecting tube 6 into the conical filter part 10 of the waste separating device 11 Most of the waste material separated from the transport air gets under the Action of about 10% residual transport air through the inlet opening 16 parallel to the waste separator 11 vertically erected buffer 15. Due to the ongoing tracking of further waste material in the Intermediate stores compressed goods and the enclosed Transport air discharged to the outside through the openings of the screen jacket 19 and removed. By adding waste material using the Transport air creates an overpressure within the accumulator which causes the free Ends of the cover sheets - are pressed outwards and thus the enable unimpeded escape of the conveyed transport air. By the continuous filling process, the residual space R within the Continuous cache. A pressure increase in the R Air volume can be avoided by the fact that the air can escape through the arranged bypass openings. This makes it possible to fill the To perform buffer 15 before emptying is carried out.
  • the emptying can be triggered on the one hand by a preselected time cycle be, or by responding to a filling level sensor, which on Buffer can be arranged at the appropriate height.
  • a filling level sensor which on Buffer can be arranged at the appropriate height.
  • the emptying interval of several combing machines must be coordinated. This means, based on the design of the pipe system or the blower can either Only one or only a limited number of combing machines be disposed of simultaneously from the contents of the buffer. That is, at Attachment of a level sensor would have to respond after this sensor there is still enough free space in the buffer to accommodate the To enable compliance with a predetermined emptying concept.
  • the air flow required for suction can be in be initiated in an optimal manner.
  • the Work process on the comber is not interrupted, it is continuously waste material via the blower 8 in the buffer delivered later.
  • this subsequent quantity is much smaller than that Quantity withdrawn during the suction process. That is, after a certain one Time is almost completely empty. This time interval for the Emptying process is usually predetermined or could also be under With the help of level sensors arranged in the buffer be determined.
  • FIG. 4 shows a further exemplary embodiment of a buffer store 15.1 remove which instead of the buffer shown in Fig. 1 and 2 15 can be used.
  • the same components of both memory designs (15, 15.1) same Reference numerals used.
  • the inlet opening 16 of the outlet pipe 14 is in the lower part of the store 15.1 arranged in its peripheral jacket 17. Above the entrance opening and with a short distance x is the intermediate store 15.1 with a air-permeable screen jacket 19 provided.
  • the sieve jacket that consists of one air-permeable filter cloth can be formed extends over less than half the total length L of the buffer 15.1 with the length L1.
  • Support rods 20 may be attached for the attachment of the filter cloth.
  • FIG. 5 shows an enlarged illustration of the bypass opening 30, which already according to the exemplary embodiment of the buffer store 15 Fig. 2 has been described.
  • the functional processes during the Filling process of the buffer store 15.1 are in accordance with the Processes which have already been described in the exemplary embodiment according to FIG. 2.
  • Intermediate store 15 no cover of the screen jacket 19 is provided because this is above the inlet opening and the problem of a wrong air supply is not as problematic during the emptying process as with the buffer 15.
  • the advantages of the buffer store 15 compared to the buffer store 15.1 lies in the fact that the delivery of waste material does not violate the Weight of the entire content of those in the buffer Mass must be delivered.
