Description

Plaster of a textile machine

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 Reinigungsab¬ section is provided.

It is known to clean working elements of a textile machine, which are prone to contamination by impurities entrained by the material to be processed, by means of a cleaning device. Such working elements are, for example, in a card, the circumferential carding of the spool and the lid. The lids fill with short fibers and dirt during the carding process. Therefore, the lid must be cleaned by a cleaning device.

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.

Usually, 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. In the actual cleaning process, 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. In this case, 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. In operation, it is therefore often clogging of the working surface of the cleaning device by impurities, so that a cleaning of the respective Arbeits¬ element is no longer guaranteed safe. If the cleaning device is to be cleaned during operation with an oscillating pivoting comb, it is also disadvantageous that during pivoting back of the pivoting comb into its starting position, an encounter takes place between the cleaning device and the pivoting comb, in which impurities are often picked up by the pivoting comb and placed on the workbench ¬ element be deposited.

It is therefore an object of the present invention to provide a cleaning device which avoids the mentioned disadvantages and ensures a secure cleaning of the affected working element.

The object is achieved by a cleaning device having the features of patent claim 1. According to the invention, 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. In a cleaning process, 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.

If 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. With an appropriate choice of the spring constant of the hinge loading spring, 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. For example, asymmetric indentations or composite materials can be used.

It is advantageous if 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.

It is particularly favorable if 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.

Preferably, 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. In a further outward section, 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 rückwärtsge¬ directed bending stronger support of the cleaning element than in a forward bending.

In an advantageous embodiment, the outer section has a chamfer at its mouth on the rearward side. By choosing the geometry of the chamfer, fine tuning of the effective bending stiffness of the cleaning transmission element possible. If, for example, too high restoring forces occur during a cleaning process, the bevelled area can be increased.

If 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 durch¬ 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.

It is also possible to provide a second cylindrical bore whose axis crosses the axis of the first bore.

It is equally advantageous if the outer section has a cone-shaped enlargement at its mouth. Such 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.

Advantageously, 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.

Suitable are bristles with a diameter of 0.1 mm to 1 mm, with a diameter between 0.25 and 0.5 mm is preferred.

The bristles may advantageously consist of a material which comprises metal, for example brass or steel. However, bristles which are made of a material which comprises a plastic, for example nylon or polyester, are also suitable. Advantageously, plastic / steel mixtures, in particular polyamide / steel used for the bristles, the mixture may contain 50 to 90% Kunst¬ material.

In the case of plastic bristles, to prevent electrostatic charging of the bristles, it may be provided that the plastic is mixed with an electrically conductive material, for example with carbon.

Furthermore, bristles may be provided which have sections of different materials. For example, a bristle may have a metal core and a plastic jacket.

In one embodiment, 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.

If 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.

If 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.

In this case, it is particularly advantageous if 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¬ gerkörper is formed in a preferred embodiment with a cylindrical outer surface. As a carrier body may be used in particular a shaft.

It is particularly advantageous if the base body is a straight cylinder or hollow cylinder with a circular base. Likewise, the basic body can be a straight cylinder or hollow cylinder with a semicircular base. However, too be created by connecting at least two main body a solid cylinder. Hollow cylinders can be easily mounted on a shaft.

In a device for cleaning the sets of revolving flat bars of a carding machine, with a cleaning device, which is rotatably mounted and driven, wherein the cleaning device can be guided along the clothings to be cleaned, the inventive advantages can be achieved when a cleaning device, spielsweise 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.

However, the advantages according to the invention can also be achieved on other textile machines with a device for cleaning a working element, if a cleaning device according to the invention is provided.

The advantages of the invention are described in more detail in the following exemplary embodiments. It shows:

FIG. 1 shows a part of a traveling cover 1 of a card. On a circulating Ket¬ te or on a rotating belt 3 is a plurality of flat bars 2 angeord¬ net. For reasons of simplification, only two pieces of the flat bars are shown. posed. The belt 3 is guided by an element 4 with a round cross-section and an axis 5. Other guide elements are available but not shown. The element 4 rotates in the direction of the arrow P1. Each flat bar 2 has a cover yarn 6, which comes into contact with the fiber material to be processed during operation of the card. The trimmings 6 are filled with contaminants and fibers and / or foreign bodies after the carding process. The trimmings must therefore be cleaned continuously during operation.

For this purpose, a cleaning device is provided, which is designed as a cleaning roller 7. The cleaning roller comprises two base bodies 10, to each of which a cleaning element 11 is fastened in a depression 12. The cleaning elements 11 are arranged such that a part protrudes from the recess 12. The main body 10 are fixed to a shaft 9 of the cleaning roller 7 and run with this in the direction of the arrow P2. The two working surfaces 19 of the main body 10 together form the lateral surface of the cylindrical cleaning roller 7. In principle, the lid cleaning can also be arranged in another area.

In the illustrated embodiment, the flat bars 2 counterclockwise and the cleaning elements 11 in the clockwise direction, wherein the peripheral speed of the outwardly facing ends of Reinigungsele¬ elements 11 are higher than the peripheral speed of the flat tops 6. Füh¬ rungskörper 4 and cleaning roller 7 are aligned with each other such that the cleaning elements 11 are guided past the peripheral sets 6 of the flat bars 2. Where the outstanding parts of the cleaning elements can penetrate to the bottom of the flat clothings, preferably in dependence on the Zustel¬ ment of the cleaning roller. During this passing, soiling is brushed off from the garnish 6. These brushed-off dirt elements are partly released into the environment, in part they adhere to the cleaning roller 7, in particular in the area of the cleaning elements 11. In order to obtain the cleaning effect of the cleaning roller 7, it is necessary to remove the adhering contaminants from the cleaning roller 7. For this purpose, a pivoting comb 13 is provided with a pivoting comb 15. The pivoting comb 13 is pivoted about an axis 14 from the initial position 13 'shown in dashed lines in the direction of the arrow P3 into an end position 13 "and along the arrow P4 back into the starting position 13. For this purpose, suitable bearings and drive elements are provided When pivoting out of the starting position 13 'into the solidly drawn position 13, the pivoting comb set 15 passes through the peripheral sets 6 of the flat bars 2. In this case, part of the impurities adhering to the sets 6 are received by the pivoting comb set 15. Upon further pivoting in the direction of P3, the pivoting comb 15 passes through the protruding ends of the cleaning elements 11. In this case, contaminants adhering to the cleaning roller 7 are taken over and continued with the pivoting comb 15. As the pivoting movement continues in the direction P3, the pivoting comb 15 passes a fixed comb 16, wherein most of the mitge led contaminants on return of the comb in the direction of P4 is transferred to the top comb 6. As an alternative or in addition, the cleaning elements could also be guided past a knock-off edge, which is not shown, and thus be cleaned. The transmission of the contaminants is ensured in a known manner by the corresponding shaping of the fixed comb or the knock-off edge as well as the shaping of the pivoting comb set 15. The contaminants can be removed from the fixed comb 16 and / or the knock-off edge, for example by suction.

When swinging back the pivoting comb 13 along the arrow P4 there is a renewed contact between the end of the cleaning element 11 and the Schwenkkammgarnitur 15. However, the transfer of dirt from the cleaning roller 7 to cover set 6 by the pivoting comb 13 is characterized by the inventive design of Cleaning roller 7 minimized or prevented.

As shown in FIG. 2, the cleaning member 11 has a fixing portion 17 and a cleaning portion 18. The fastening section 17 is arranged in a recess 12 in the base body 10 and the cleaning section 18 protrudes from the recess 12. The cleaning element 11 is in the indicated by an arrow teten working direction AR on the element to be cleaned of the textile machine, so spielsweise guided past the flat set 6. In this case, the cleaning section 18 is deflected out of the starting position 11 counter to the working direction AR, ie, directed backwards, into a cleaning position 1.1 "in Fig. 2. The fastening section 17 of the cleaning element 11 is firmly clamped in. The deflection from the starting position of the cleaning element 11 in the position shown in dashed lines 11 "takes place exclusively by a bending of the cleaning element 11. A deflection in the direction of AR in the position 11 'is also possible.

Since the mounting arrangement 11 is mounted asymmetrically in the recess 12, it comes in a rearward deflection S2 to a greater bending of the cleaning element 11 than in a deflection S1, which has the same amount S but the opposite direction. FIG. 2 illustrates the basic idea of the invention. Preferred embodiments of the mounting of the cleaning element 11 are described in more detail in the further figures.

Due to the greater bending in the case of a deflection in direction S2, higher restoring forces result in the direction of the initial position than in the case of a deflection by the same amount S in direction S1. A deflection in the direction S2 results when the cleaning element 11 is brought forward in the working direction AR on the part to be cleaned

Element 6 of the textile machine. When the cleaning element 11 comes into contact with the pivoting comb 13, in its backward movement in the direction P4, the bending takes place in the direction S1. As a result of the lower forces arising here, in the form of a greater deflection, a return of dirt from the cleaning end 18 of the cleaning element 11 on the pivoting comb 13 is prevented.

After a deflection of the cleaning element 11, the end 18 of the cleaning element 11 performs a strongly damped periodic oscillation and after a certain time returns to its starting position. Since the restoring force at a deflection in direction S1 is less than usual, the amplitude of the Vibration increased. This leads to an improved self-cleaning of the cleaning roller 7.

FIG. 3 shows the work surface 19 of the main body 10 of a cleaning device according to the invention, which is developed into the plane. The working surface 19 is the lateral surface of a half-cylinder or a half-hollow cylinder. A plurality of depressions 12 with cleaning elements 11 fastened therein are distributed over the working width of the working surface 19. The cleaning elements 11 have a substantially round cross-section and are mounted asymmetrically in the bores 12. When passing the working surface 19 in the working direction AR on an element to be cleaned, the cleaning elements 11 are supported by the wall of the recess 12.

If the depressions 12 are to be arranged with a small lateral offset AS, it is advantageous to arrange the depressions 12 in a zigzag line on the working surface 19. A small lateral offset AS is required if the cleaning effect of the cleaning device should be ensured without interruption over the entire working width. The laterally measured distance A is an oblique arrangement greater than the lateral offset AS, which is favorable for the stability of the base body 10. Preferably, however, the depressions can also be distributed in a spiral over the base body.

FIG. 4 shows a further embodiment with a cleaning element 11, which is mounted asymmetrically in a recess 12. Recess 12 and cleaning element 11 extend substantially over the entire working width of the working surface 19. In the embodiments according to Figures 3 and 4 are fastening means 20 for fixing the base 10 to a shaft or another element, spielsweise, a further base body 10 of Plaster provided. By joining two basic bodies 10 according to FIG. 3 or 4, a cleaning roller 7 according to FIG. 1 can be produced. Alternatively, however, the main body 10 could be a solid cylinder or a hollow cylinder. FIG. 5 shows a cleaning element 11, which is mounted in a depression 12 of the base body 10. The attachment portion 17 of the cleaning member 11 is disposed on a holder 35. The holder 35 is connected by a hinge 22 to the Grundkör¬ by 10. The cleaning section 18 protrudes from the recess 12. The cleaning element 11 comprises a plurality of bristles 21, which are aligned substantially parallel. The hinge 22 allows a deflection of the cleaning section iδ in the working direction AR. An opposite deflection is prevented by the stop 24. A compression spring 23 counteracts a deflection of the cleaning element 11. A deflection of the working section 18 in the working direction can be composed of the sum of the deflection of the hinge 22 and of a bending of the bristles 21. However, a backward deflection can only arise by bending the bristles in this direction. As a result, the cleaning portion 18 can be deflected forward with less force than to the rear. In this case, the deflectability can be selected by an appropriate choice of the spring constant of the spring 23 and by the selection of bristles with a corresponding bending stiffness.

The cleaning element 11 according to FIG. 6 has a forward-directed section 25, which comprises bristles 21 a, which are shorter than the bristles 21 b, which are arranged in a rear-facing section 26. In a backward bending of the cleaning element 11, the long bristles 21a are supported by the short bristles 21b. This results in an increased restoring force in this direction. FIG. 6 shows two sections, each of which comprises bristles of equal length. The contour therefore has a step shape. It is also conceivable, however, an arrangement in which the outer contour forms a slope.

FIG. 7a shows the cross section of the depression 12 in the base body 10 according to FIG. 3. The depression 12 has an inner section 27 and an outer section 28. The inner section 27 consists of a cylindrical bore 29 with the axis 31. The outer section 28 comprises a bore 30, with a diameter which is larger than that of the first bore 29. The axis 32 of the bore 30 is offset in parallel in the direction of the working direction relative to the axis 31 of the bore 29. in the Mouth region of the recess 12 is a conical widening 34 is provided, wo¬ at a chamfer 33 in the working direction facing side part of the cone "34 is.

FIG. 7b shows the depression 12 according to FIG. 7a and the arrangement of the cleaning element 11 therein. The cleaning element 11 is in the inner portion 27 of the Vertie¬ tion 12 fitted form-fit on all sides. In the outer section 28, in the working direction AR, there is a greater range of movement for a bend in the cleaning element 11 than in a bending opposite the working direction. The starting position of the cleaning element is denoted by the reference numeral 11 in FIG. 2, the position facing the working direction AR by the reference numeral 11 "and the position pointing in the working direction by the reference numeral 11 ' straight contour.

This type of storage results in a backward bending, for example, when cleaning a working element 6 of a textile machine, to a higher bending stiffness than in a forward bending, which occurs for example in an undesired encounter with the pivoting comb 13.

By the cone 34, the bending behavior of the cleaning element 11 can be influenced in the ge desired manner. Furthermore, the cone counteracts unwanted Wi¬ ckelbildung from deposited fibers. A portion of the length of an attached fiber remains in the cone, whereby the longitudinal extent of the deposited fiber on the outer surface of the body 10 is shortened.

The cross-section of a recess 12 shown in FIG. 7 a can also be used in the case of an embodiment of the cleaning device according to FIG. 4. However, the holes 29 and 30 are then not cylindrical, but form as slots or as Fräsrillen aus¬.

8a shows an alternative embodiment of the recess 12. The outer section 28 is here by a second bore 30, for example, a cylindrical or conical bore tion, executed with a tilted axis 32. This embodiment could be provided with a mouth chamfer 33. The cross section shown can also be used in an embodiment of FIG. 4, provided that the cylinder bores are replaced by slots. FIG. 8b shows the arrangement of a cleaning arrangement 11 in the depression 12 according to FIG. 8a. Here, too, the outer end of the cleaning element 11 can be deflected more easily in the direction of the working direction than counter to the working direction.

Figure 9 shows a base body 10 is formed band-shaped. The band-shaped main body is wound around a cylindrical carrier body 36. As a carrier body 36, for example, the shaft 9 of the cleaning device can be used. The main body 10 may be, for example, a band made of rubber or plastic, possibly with a Zugver¬ reinforcement. The cleaning elements are arranged in a manner already described in recesses 12 on a longitudinal side of the main body 10, which advantageously lies opposite the carrier body.

The invention is not limited to the exemplified and described exemplary embodiments. For example, it can be provided that the Grundkör¬ by 10 and the cleaning element 11 are made in one piece.
