Definitions

  • the invention relates to a cleaning machine for cleaning fiber material.
  • a cleaning machine for cleaning fiber material.
  • raw cotton typically contains between 3% and 8% impurities such as sand, dust, husks and other foreign objects. These impurities should be removed as completely as possible, with as few good fibers as possible being separated from the raw cotton and the remaining fibers being damaged as little as possible by the cleaning process.
  • impurities should be removed as completely as possible, with as few good fibers as possible being separated from the raw cotton and the remaining fibers being damaged as little as possible by the cleaning process.
  • the higher the degree of cleaning both the loss of good fibers and the deterioration of the fibers increase.
  • the raw cotton is usually delivered to the spinning mill in pressed bales.
  • the unwanted dirt is firmly embedded in the raw cotton.
  • a large number of cleaning devices or cleaning machines arranged one after the other are provided in the spinning preparation lines that are customary today. Cleaning machines of the type described here have one or more rotating cleaning rollers.
  • the opening, also called dissolving, of the fiber material transported along a cleaning roller is brought about by a mechanical action of the driven cleaning roller on the fiber material. This mechanical action also removes dirt from the fiber material.
  • the opened or dissolved fiber material, together with the dirt now loosely contained therein, is guided past cleaning elements arranged in a bowl-like manner on the cleaning roller. Part of this fiber material is discharged to the outside through the cleaning elements, for example by gravity, centrifugal force or by an air flow. In relation to the supplied, uncleaned fiber material, this includes that removed by the cleaning elements Part of the fiber material, which is also called waste, contains a large proportion of dirt and trash. As a result, the fiber material not guided through the cleaning elements is ultimately cleaned. However, the waste also contains a certain proportion of fibrous material, which is undesirable but unavoidable.
  • Cleaning devices which have a plurality of cleaning rollers and cleaning elements are disclosed, for example, in DE 44 39 564 B4 . Three successive cleaning rollers are fitted therein, each of which has a separating knife on its circumference. Next revealed the EP 1 866 468 a cleaning machine with a cleaning roller, which has a large number of grate bars on its circumference for separating waste.
  • each machine type has its own machine frame.
  • Various attachments can be provided in a machine frame in order to install additional or optional elements in the machine frame, but in principle the machine cannot be expanded or converted to another machine type without great effort.
  • a disadvantage of the known constructions of cleaning machines is that an extension or enlargement or reduction of the cleaning machine is expensive. This means that different cleaning machines must be used for the various cleaning functions.
  • the object of the invention is therefore to create a device that allows a simple construction of cleaning machines, which allows a simple adjustment of the cleaning performance to different needs.
  • a cleaning machine for cleaning fiber material which in a basic design has a machine base, a fiber material inlet, a fiber material outlet and at least one cleaning module, the cleaning module being provided with a cleaning roller and at least one cleaning device, and the cleaning device being at least partially is arranged shell-like around the cleaning roller and the cleaning roller has a cleaning roller axis.
  • the fiber material inlet and the fiber material outlet and the cleaning module are designed as self-supporting modules.
  • the cleaning module and the pulp outlet are on the machine base and the pulp inlet is held on the cleaning module.
  • the individual elements of the basic version contain all the installations required for operation, such as drives, sensors, fiber guide elements, etc. Since these installations must of course be available for operation, they are not listed in detail.
  • the basic version contains a machine base, a fiber material inlet, a fiber material outlet and at least one cleaning module.
  • the machine base is the lowest part of the cleaning machine on which the entire machine is built and which also represents the link between the elements and a foundation.
  • the machine substructure is supported on the foundation using appropriate machine feet or firmly anchored in the foundation, for example screwed. The other elements are then assembled on the machine base.
  • the fiber material inlet forms an interface between a fiber material feed and the cleaning module.
  • fiber feed is not part of the cleaning machine and can be of various types.
  • the fiber material can be guided into the fiber material inlet via a conveyor belt or a chute.
  • the module with the fiber material entry is set up independently of the other modules on the machine base.
  • the cleaning module is mounted on the machine base and connected to the fiber material entry.
  • the fiber outlet is placed on the machine base and connected to the cleaning module.
  • the module of the fiber material outlet contains only the elements which are necessary for a transfer of the fiber material from the cleaning roller in the cleaning module to the removal of the fiber material from the machine.
  • the fibrous material which is brought into the cleaning machine through the fibrous material inlet, leaves the cleaning machine again through the fibrous material outlet after passing through the cleaning module.
  • the advantage of this construction of the cleaning machine from self-supporting modules is that the internals of individual modules are not connected to the internals of adjacent modules. As a result, the individual modules can be completed before they are assembled, and the construction work on the cleaning machine is reduced to a minimum, namely the assembly of the modules.
  • Self-supporting modules are characterized by a closed construction, which can be transported and lifted to its assigned location without additional stabilization.
  • the individual modules with each other as well as the modules with the machine substructure are coupled to each other by simple connecting means.
  • many possibilities such as screw connections, clamp connections or quick-release fasteners are known from the prior art.
  • the connections are designed in such a way that the cleaning machine is dust-tight, but the individual elements or modules can also be easily separated from one another again. In this way, the possibility arises of obtaining a cleaning machine which can be used for various tasks.
  • the cleaning machine can be supplemented with additional cleaning modules as required individual elements or modules can simply be exchanged for modules with different built-in components in order to provide the required cleaning performance.
  • the machine substructure always remains in its original form, which means that the cleaning machine does not have to be repositioned.
  • the cleaning device is advantageously formed from a large number of cleaning elements in the form of grate bars.
  • Grates are segments that typically enclose one quarter to three quarters of the opening roll. It is also possible to assign several grates to an opening roller. Grates consist of several individual, angular grate elements that ultimately form a shell. In addition to slotted plates, perforated plates, angle bars and knives, grate bars with a triangular cross-section are primarily used as grate elements today.
  • Grates have the advantage that the impurities or dirt particles, which are transported outwards by centrifugal forces acting on the fibrous material as a result of a rotation of the cleaning roller, and are thrown through the grate away from the cleaning roller. This separates the impurities from the fibrous material, with the fibrous material being transported past the grate elements by the cleaning roller. The impurities separated from the fiber material in this way fall away from the cleaning roller and are collected in a container in the machine base.
  • the cleaning device is formed from a large number of cleaning elements in the form of separating knives.
  • Separating knives are known from the prior art and, compared to a grate, have the advantage that they are built closer to the fiber material transported through the cleaning roller. As a result, the contamination or dirt particles are largely stripped off the fiber material and not only the contamination thrown away is caught. The contaminants separated in this way are collected directly after the separating knives in exhaust air pipes, which extend over the extension of the separating knives, and transported away by air.
  • the cleaning device is designed as an insert, with the insert being designed in such a way that it can be accessed from outside the Cleaning module is removed or introduced in the direction of the cleaning roller axis.
  • This has the advantage that the cleaning device can be replaced without having to intervene in the machine itself.
  • the individual cleaning elements, in the case of separating knives, or all cleaning elements together, in the case of grate elements, can be removed.
  • the cleaning device can thus be prepared or serviced outside the cleaning machine in a simple manner and then exchanged as a coherent element without causing a lengthy operational interruption.
  • the cleaning device is preferably designed as a grate with a large number of grate bars and is provided with a coupling for establishing a connection with an actuator for adjusting the grate bars.
  • the individual grate bars are fitted with a coupling either separately or as a combination.
  • Grate bars used in cleaning machines today are adjustable. For example, grate bars can be twisted or moved closer to the cleaning roller, which can affect the cleaning performance.
  • An easy-to-release coupling with an adjustment device means that the cleaning device can be replaced with a slide-in unit.
  • the cleaning machine preferably has a second cleaning roller with a second cleaning insert, the second cleaning roller with the second cleaning insert being designed as a self-supporting additional module. If the cleaning performance is now to be increased, a further cleaning module can be inserted between the fiber material inlet and the cleaning module or between the cleaning module and the fiber material outlet. Here, for example, the fiber material outlet is separated from the cleaning module and from the machine base and is shifted so far on the machine base that a second cleaning module with an additional cleaning roller can be used. This process can be repeated with a further additional module, so that in a particularly preferred embodiment the cleaning machine has a third cleaning roller with a third cleaning insert.
  • the additional modules used are also designed as self-supporting modules.
  • the machine substructure is provided for the structure of the fiber material outlet and a cleaning module and one or two additional modules.
  • the construction of the machine substructure is designed in such a way that no changes have to be made to the construction itself if an additional module is inserted or removed. By attaching simple covers, the machine base can be adapted to the existing cleaning and additional modules.
  • the machine base has at least one cellular wheel sluice for removing the impurities.
  • the impurities fall into a cell of the sluice. When the sluice is rotated, this cell is brought into a position in which the impurities are removed from the cell by means of an air flow.
  • the machine base has a waste container. This is used for simple collection of impurities, with the container being emptied periodically by automatic suction or manually.
