Definitions
- the present invention relates to a cleaning device for a textile machine, with ei ⁇ NEM basic body and with at least one cleaning element, wherein at one end of the cleaning element a connected to the main body mounting portion and at another end of a protruding from the body lotsab ⁇ section is provided.
- Known cleaning devices have a main body with an outwardly facing working surface. This work surface can be delivered to the work element to be cleaned. Furthermore, known cleaning devices have at least one cleaning element, wherein one end of the cleaning element is designed as a fastening section and is connected to the base body. The other end of the cleaning element is designed as a cleaning section and protrudes above the working surface from the base body.
- the base body comprises a plurality of cleaning elements, preferably in the form of bristles, for example, a plurality of bristles, which are arranged on the base body in the manner of ein ⁇ side clamped leaf spring.
- the free end of the cleaning element thus formed is guided past the work element to be cleaned in a specific working direction in a translatory or rotational manner.
- the bristles are bent counter to the working direction, pick up the dirt and, after passing through the work element to be cleaned, return to their starting position.
- the disadvantage here is that the dirt received by the cleaning device adheres so firmly to the cleaning device, so that it can not always be safely removed even with conventional facilities, such as tee-off edges or pivoting combs.
- the cleaning device has a cleaning element, which is designed and / or stored such that a deflection of the cleaning section by a certain path length in the working direction requires less force , acting as a deflection by the same path length in the opposite direction.
- the working direction is that direction in which the cleaning device is guided along the work element to be cleaned in operation.
- the cleaning section of the cleaning element is deflected by the contact with the working element counter to the working direction.
- the Weglän ⁇ ge of the deflection results from the respective geometric arrangement of the cleaning device with respect to the working element.
- the cleaning element is designed and / or mounted so that at least part of the cleaning element or the bearing is elastically deformed by the deflection. This creates a force which counteracts the deflection. After the cleaning element has passed the working element, the cleaning section swings back beyond the starting position, whereby a deflection of the cleaning section takes place in the working direction. The result is a strongly damped periodic oscillation. Since the cleaning element is designed and / or stored so that the restoring force is smaller for the same path length of the deflection, this deflection results in a larger amplitude than in conventional cleaning devices. This counteracts the strong adhesion of soiling to the cleaning device.
- the principle described causes when passing the cleaning element at a knock-off edge by increasing the vibration amplitude to a detachment of accumulated dirt residues. These dissolved dirt residues can then be removed, for example, with an extraction system.
- a pivoting comb is guided past an inventive cleaning device during pivoting back so that the projecting cleaning section of the cleaning element is deflected in the direction of the working direction, the greater deflection causes less dirt material to be transferred from the cleaning elements on the pivoting comb and thus no deposits on the working elements, such as B. the lid.
- the attachment portion of the cleaning element may be arranged on a holder which is connected via a spring-loaded hinge with the base body.
- the hinge is designed so that a deflection of the cleaning element from a starting position in the working direction is possible.
- the deflectability of the cleaning element against the working direction is prevented by the design of the hinge, for example by a stop surface.
- a deflection of the cleaning element is possible by an elastic deformation of the cleaning element or storage.
- the desired restoring force can be selected.
- Hinges can be dispensed with if the flexural rigidity of the cleaning element is lower in the case of a deflection of the cleaning section towards the front, that is to say in the working direction, than in the case of a reverse pointing end, ie opposite deflection.
- Directional bending stiffnesses can be achieved, for example, by the structure of the bristles.
- asymmetric indentations or composite materials can be used.
- the cleaning element is mounted such that it bears on a bend in one direction over a smaller part of its length or is supported than in an opposite bend.
- the attachment section is arranged in a depression of the work surface. In this way it is possible to prevent the adhesion of dirt in this area.
- the recess has an inner portion in which a first part of the fastening portion of the cleaning element is fitted positively on all sides.
- This inner section is used to attach the cleaning element to the Grund ⁇ body. Its shape depends on the design of the attachment portion.
- the attachment can be done in any suitable manner. For example, it is possible to glue into the fastening section, press in, clamp in or screw it in about.
- a movement space is provided between the initial position of the cleaning element and the wall of the depression. The movement space on the backward side is smaller than that on the forward side. This results in a schncege ⁇ directed bending stronger support of the cleaning element than in a forward bending.
- the outer section has a chamfer at its mouth on the rearward side.
- the attachment portion of the cleaning element has a round cross section, it is particularly advantageous if the inner portion is formed as a first, preferably cylindrical or conical, bore.
- the bore can ist ⁇ commonly or as blind bore and is easy to produce.
- the outer portion may be formed by a second, also preferably cylindrical or conical bore, which has a larger diameter than the bore of the inner portion, wherein the axes of the bores are offset in parallel. Due to the offset position of the bores, it is possible in a simple manner to design the movement space between the starting position of the cleaning element and the wall of the recess.
- the outer section has a cone-shaped enlargement at its mouth.
- a cone has a positive effect on the unwanted clogging of the work surface in many cases. For example, sets one end of a dirt fiber at the transition from the body to the cleaning element, so remains part of the length of the fiber in the cone, whereby the remaining length of the fiber is shortened to the surface. This counteracts the so-called winding formation, in particular with rotating cleaning devices.
- the cleaning element comprises one or more bristles or scrapers, which are preferably rod-shaped.
- Bristles may, for example, be bent in a U-shape, wherein the bottom of the U may be fastened, for example, with a plug or a clamp in a recess in the base body.
- Bristles can in principle have any cross section. However, round, oval or square cross sections are preferred.
- the bristles may advantageously consist of a material which comprises metal, for example brass or steel.
- bristles which are made of a material which comprises a plastic for example nylon or polyester, are also suitable.
- plastic / steel mixtures, in particular polyamide / steel used for the bristles, the mixture may contain 50 to 90% Kunststoff ⁇ material.
- the plastic is mixed with an electrically conductive material, for example with carbon.
- bristles may be provided which have sections of different materials.
- a bristle may have a metal core and a plastic jacket.
- the cleaning element has a plurality of rod-shaped bristles or scrapers, the length of the bristles or scrapers being varied in sections. On a forward section of the cleaning element, the bristles or scrapers have a greater length than on a rear section. In a bending of the cleaning element against the working direction, the shorter bristles or scrapers support the longer. As a result, the bending stiffness of the arrangement is increased in this direction.
- the main body of the cleaning device may consist of a material which
- Plastic for example PVC includes. Again, to prevent an electrical Rostati charge an electrically conductive material are added. Again, carbon comes into consideration.
- the cleaning device is provided for the purpose of translating past a working element to be cleaned, it is preferred to design the working surface as a flat surface of the base body. If the cleaning device is to be guided rotationally past the work element to be cleaned, it is also possible to carry out the work surface as a curved surface of the main body.
- the cleaning device is to be arranged in a rotating manner on the working element to be cleaned, it is advantageous if the cleaning device has a shaft on which at least one main body with at least one cleaning element is arranged.
- the cleaning element is arranged on a cylindrical surface which is coaxial with the shaft.
- a cylindrical surface is the lateral surface or a part of the lateral surface of a preferably straight circular cylinder.
- the cleaning element can also be arranged on a conical surface, which is arranged coaxially to the shaft.
- a conical surface is the lateral surface or a part of the lateral surface of a preferably straight circular cone.
- the base body may be designed in strip form and be wound around a carrier body in the manner of a helical line, wherein preferably the cleaning element is arranged on the side facing away from the carrier body of the base body.
- the Trä ⁇ ger entrepreneurial is formed in a preferred embodiment with a cylindrical outer surface.
- a carrier body may be used in particular a shaft.
- the base body is a straight cylinder or hollow cylinder with a circular base.
- the basic body can be a straight cylinder or hollow cylinder with a semicircular base.

- the inventive advantages can be achieved when a cleaning device, spielmud a cleaning roller according to the present invention is formed.
- a swivel comb with a swivel comb set for removing contaminants from the plastering device and / or from the flat rods can be provided on the device.
- the pivoting comb can be designed, supported and driven in such a way that, when pivoting in a first direction, it is guided past the cleaning device and the cover in such a way that it decreases dirt from both elements. When it is pivoted, it can dispense these contaminants with a second direction, which is opposite to the first direction, at a fixing comb and / or at a knock-off edge. When swinging back the pivoting comb in the cleaning device, the transmission of dirt from the cleaning device to the pivoting comb is reduced or prevented by the inventive design of the cleaning device.
