Definitions
- the invention relates to a working element on a fiber-processing machine having at least one roller, wherein the working element of the roller is arranged at a distance opposite.
- the working element extends over the entire working width of the roller, wherein a part of the working element is formed as a suction channel.
- the working element has at least one Ausscheidemesser and another carding or covering. Between the carding or covering and the Ausscheidemesser is an opening with an ejection distance. The opening connects a space between the working element and the roller with the suction channel.
- the invention also relates to an associated method for adjusting the ejection distance and a closure element for use in apparatus and method.
- Spinning preparation plants use machines such as cleaners or carding machines, which contain various working elements for cleaning, sorting, opening, carding, etc. of the fibers to be processed.
- the various types of fibers are processed, including cotton fibers or man-made fibers or mixtures thereof.
- the parts or fibers are usually separated from the Ausscheidemesser of a rotating roller.
- an opening in the working element is provided against the drum before the Ausscheidemesser, the width of this opening is called the ejection distance. After the separated parts have passed the knife, they are fed to a suction and conveyed away.
- document CH 639 434 A5 describes a dirt separator which has a knife blade spaced radially to the drum of the card as well as a likewise radially spaced collecting rail. A gap has been left between the collecting rail and the knife blade. The space bounded by the knife blade and the collection rail is covered and forms a vacuum suction chamber. The clear width between the collecting rail and the knife blade is adjustable by Correspondingly provided adjusting screws.
- a setting of the ejection distance, the gap between knife blade and safety rail is complex, since on the one hand the accessibility of the screws is given only after opening the vacuum Saugcroabdeckung and on the other hand, the adjustment must be made via several screws, which requires a constant review of the setting by quantitative measurement power.
- Another cleaning element with a Ausscheidemesser discloses the document DE 39 02 204 A1.
- the ejection distance is determined by the distance between the knife blade and the upstream element.
- a guide element is attached, which can be pivoted into the ejection distance and thereby changes the size of the ejection distance.
- the guide element is arranged to be movable, which can lead to an undesired adjustment during operation.
- the shape of the element must also be ensured for a longer construction by a correspondingly complex construction. Due to the fact that guide element and knife blade are not arranged on the same cleaning element, the accuracy of the adjustment is impaired by the independent attachment of the individual cleaning element to the machine.
- the European patent application EP 0 388 791 A1 also discloses a device for separating dirt with the aid of a knife blade, which allows an adjustment of the ejection distance.
- the setting of the separation gap between the knife blade and the upstream carding element is carried out by adjusting screws.
- the screws are freely accessible in the disclosed embodiment, without a part of the device must be dismantled. The complex adjustment due to several distributed over the length of the working element screws remains, however.
- Object of the present invention is therefore to provide a working element of the type mentioned, which does not have the mentioned disadvantages of the known prior art and allows easy adjustment of the ejection distance.
- a working element which has a receptacle in which a closure element is held stationary by means of a clamping force, wherein the ejection width is given by the shape of the closure element.
- Ausscheidemesser For the removal of debris and short fibers at different points in fiber processing machines Ausscheidemesser be used. These elimination knives are embedded in working elements or are in the form of grates directly opposite rollers, which transport the fibers and lead them past the elimination knife.
- the inventive design of a provided with a Ausscheidemesser working element is used in the fine cleaning, preferably in machines for carding of fiber material.
- the working element includes various devices such as the actual knife blade, carding or cover elements. Other devices such as measuring devices, sampling devices, guide elements and suction channels can also be accommodated in the working element.
- the working element itself is shaped as a suction channel. However, it is quite common to use a separate or attached suction channel for the extraction of the parts deposited on the knife blade, even in such a case the suction channel is attributed to the working element as a component thereof.
- the working element is composed of a carrier and the devices held on the carrier.
- the carrier is placed opposite a roller, for example a pre-cutter roller or a drum of a card.
- the carrier and thus also the working element extend over the entire width of the corresponding roller or drum.
- the carrier is supported at the outer ends of the roller on the side shields of the machine, in which normally also the roller spotting drum is stored.
- the support of the carrier takes place in various ways, usually the support is designed such that a certain distance between the roller or a set on the roller and the working element can be adjusted.
- the carrier is composed of several parts.
- the two parts which are for example made as hollow profiles, held together with a clamp.
- the clamp is mounted on the side of the working element facing away from the roller.
- the two carrier parts are shaped so that they form a suction channel in the assembled state.
- the roller opposite the carrier is a knife blade attached.
- the knife blade is attached to the roller at an angle to the tangent so that the tip of the knife blade directed against the roller points counter to the direction of rotation of the roller and functions as a selector blade.
- the attachment of the knife blade on the carrier can be made interchangeable as well as adjustable.
- a carding element is mounted in front of the knife blade.
- this carding element is also attached to the support of the same working element as the knife blade.
- This upstream Kardierelement can be provided with a set or be designed as a cover.
- the attachment of the carding element on the support of the working element can be made adjustable in a known manner.
- the cover is integrally formed on the support of the working element.
- the carrier profile is designed such that the roller-facing surface of the carrier forms the cover. If the use of a carding element is not provided, the result of this embodiment of the support of the working element is the advantage of a favorable production, since it is possible to dispense with the formation of fastening possibilities for a separate carding element or covering element.
- the size of the ejection distance is determined by the arrangement of the Ausscheidemessers, the installation of the working element and the properties of the fiber material to be processed. As the size of the ejection distance increases, so does the amount of waste.
- the present invention enables easy adjustment of the ejection distance. Such an adjustment of the ejection distance may be necessary in a batch change, a conversion of the material to be processed or a conditionally determined by fabrication specifications higher excretion. Due to the possibility of adjusting the ejection distance, a structurally identical working element can be used for different installation locations and only the setting of the ejection width can be changed.
- the adjustment of the throw distance is done by simply replacing a closure element.
- a receptacle is provided opposite the separating knife into which a closure element can be inserted.
- this insertion of the closure element takes place by insertion in the direction of the axis of rotation of the roller.
- This has the advantage that the working element does not have to be accessible in its interior in order to be able to introduce the closure element.
- the adjustment of the working element or cutting knife is not changed by the insertion of a closure element.
- the ejection distance is thereby variable independently of the setting of the knife blade with respect to the roll surface.
- the receptacle provided in the carrier of the working element is shaped in such a way matched to the closure element, that the closure element is held by a clamping force.
- the necessary clamping force for attachment can be generated by deformation of the closure element.
- different attachment points may be provided, in which the closure element and the receptacle are specially shaped to generate the clamping force.
- the recording of the working element and parts of the closure element can be formed such that they function as a snap connection, in which deforms a component and hooked with the recording in the other component.
- a clamping force generating clamping means is inserted between the working element, respectively carrier of the working element, and the closure element in the receptacle.
- the clamping means may be designed as a spring element, for example made of elastically deformable material or in an elastically deformable construction.
- the clamping means can also be designed as a wedge element or under certain environmental conditions expanding element.
- a spring element such a spring element can vary in its dimension, so that it does not extend over the entire length of the working element.
- the use of several distributed over the length of the working element spring elements leads to a preferred embodiment.
- the individual spring elements are immovably embedded in the receptacle on the support of the working element, so that they are not crazy even when introducing the closure element.
- the receptacle in the support of the working element and the counterpart formed on the closure part are formed in their dimensions in such a way that the closure element can be captively inserted into the support. As a result of the shaping of the closure element and the receptacle, the closure element can not fall out transversely to the axis of the roller.
- the introduction of the closure element can by a latching in a
- Snap connection or insertion in the presence of a clamping means or a combination thereof Under a latching is a clip-like attachment to understand.
- the closure element is laterally inserted into the working element and subsequently introduced into the receptacle with a movement transverse to the axis of rotation of the roller, where the formations snap on the closure element at the intended locations.
- a clamping force is generated, which holds the closure member in a predetermined position and thus causes a predefined adjustment of the ejection distance due to the geometric dimensions of the closure element.
- Such a snap connection can be effected by a deformation of the components involved in the snap connection or triggered by inserted spring elements.
- the receptacle in the support of the working element is designed as extending over the entire length of the working element respectively carrier groove.
- the clamping force generating spring elements which are necessary in such an embodiment can extend over the whole or only over part of the length of the working element.
- the spring elements are integrally formed on the closure element or are inseparably connected thereto and are introduced together with the closure element in the recess designed as a groove.
- An inseparable connection results, for example, from coherent connections or gluing.
- the receptacle in the working element can be closed on one side of the carrier and on the other side, where the insertion of the closure element takes place, be made lockable, to prevent lateral displacement of the Ver gleichememen- tes.
- the receptacle and the closure element are formed such that the closure element is held captive in the receptacle transversely to the insertion direction, even in the case of failure of the clamping means.
- the ejection distance is limited after insertion of the closure element by the Aus ⁇ the knife diameter opposite surface of the closure element.
- the ejection distance can be adjusted.
- the ejection distance by inserting the closure element, the ejection distance equal to zero, and thus the opening which the space between the see and the carding respectively covering connects with the suction, closed ,
- an elimination can be prevented without the work item having to be replaced. This brings the extra Advantage that without adjustments in a renewed replacement of the closure element, the previous setting of the working element or Ausscheidemessers is restored. Closing of the working elements with Ausscheidemesser is advantageous in the processing of synthetic fibers.
- the surface of the closure element opposite the separating knife can be designed as a surface with a contour or a structured surface.
- the shape of the surface and its surface structure can be designed such that the flow in the space between the closure element and the Ausscheide- knife is affected. Thereby, the geometric shape of the opening between the Ausscheidemesser and the closure element is given with the design of the closure element.
- the closure element By inserting the closure element, this is the carding element or cover connected downstream in the direction of rotation of the roller.
- the surface of the closure element facing the roller forms a continuation of the surface of the cardiac element or covering element.
- the roller facing surface of the closure element is offset in comparison to the preceding element.
- the gap between the roller surface and the carding element widens to the gap between the roller surface and the closure element.
