Definitions
- the invention relates to a revolving flat card with a drum and, a working width of the drum spanning decking unit comprising revolving deckle, which are stored on both sides outside the working width, the drum and moving lid are provided with sets, which are on a part of the circulation of Opposite cover and thereby form a carding room between them; and a revolving lid and adjustment method.
- the lid area together with the drum forms the main carding zone and, as a function, has the dissolution of the flakes into individual fibers, removal of impurities and dust, elimination of very short fibers, the dissolution of nits and the parallelization of the fibers. Since the lids used are due to their function by dirt and fibers added, it is necessary to clean them. Therefore, the revolving lid has been developed, wherein the lid are held together by means of a chain or a belt and combined to form an endless, revolving band. During one revolution of the lid, also called lid travel, a part of the lid is always in direct use opposite the drum unit. The remaining part of the lid is transported backwards on pulleys and can be cleaned during this phase and possibly ground.
- the width or the part of the axial length of the drum, which is covered with a set forms the working width of the card.
- This working width is formed between the respective set of a moving lid and the clothing of the drum a space, the carding room.
- a narrow gap is created, called the carding nip.
- the carding chamber or carding gap results from the fact that the revolving lids, guided by arcuate strips, so-called flexible sheets, are guided along the circumference of the drum in a distance determined by these flexible sheets.
- the revolving lids span the entire working width of the drum and are held at both ends by the said chains or straps and guided by the flexible arch.
- the size of the Kardierspalts lies with a revolving flat card between 0.10 to 0.30 mm for cotton or up to 0.40 mm for man-made fibers. Therefore, the precise guidance of the revolving lids by the flexible bend and the construction of the revolving lids is of central importance.
- the existing between the set of the drum and the set of a revolving door carding is not constant due to various influences during a cover journey and over the working width of the lid. Due to the changing operating conditions in the area of the carding nip resp. the Kardierraumes, such as the temperature conditions, the clothing load by receiving dirt and other disposal or acting on the revolving lid or the drum forces such as centrifugal or gravitational force, the carding is influenced in its geometry. Due to the influence of the rising during operation temperature in the region of the carding room is an expansion of the drum and the revolving lid. These temperature conditions change on the one hand during a cover trip and on the other hand over the working width.
- the temperature in the carding chamber is not the same in the lid inlet area as in the lid outlet area.
- the cover inlet area represents the end of the main carding zone seen in the drum rotation direction in opposite operation of the revolving flat top unit. Accordingly, the beginning of the Hauptkardierzone the cover outlet area seen in the drum rotation direction assigned. Due to the carding work to be done, the revolving lid is heated during its lid travel through the main carding zone. Because there is no uniform air flow over the working width of the drum, the heating of the revolving lid is not even over the course of the working width. Similar influences are also due to gravity. The moving lids are usually guided from below over a highest point and in turn down the drum circumference.
- EP 1 687 467 B1 discloses a system in which the opposing elements have a concave arc to compensate for the thermal deflection of the elements.
- the revolving covers as well as the drum are manufactured with a predetermined curvature which is matched to the thermal deflection resulting during operation of the machine such that the incorporated curvature and the deflection resulting from the heating cancel each other out.
- DE 10 2006 014419 A1 discloses a system which, by supplying energy, in particular heat, attempts to achieve a countermovement to the operational deformation of the carding elements. By thus changing the contour of the carding a consistent carding nip while changing operating conditions should be achieved.
- the system has the disadvantage in an application for movable carding elements such as the revolving lid that a contour change achieved by heat is too sluggish to allow for a change dependent on the lid position.
- the prediction of the expected change in shape when exposed to thermal energy is difficult and highly dependent on the specific characteristics of each individual touring lids.
- it results from a supply of heat energy the disadvantage that the heat balance of the card is changed, which in turn can lead to an undesirable influence of other components.
- the invention has for its object to provide a Wanderdeckelkarde of the type described above, which avoids the disadvantages mentioned and adapted to the operating conditions during a cover travel as well as over the entire working width of the Wanderdeckelkarde carding between drum set and revolving deck set allows.
- the object is solved by the features in the characterizing part of the independent claims.
- To solve the problem it is proposed to provide a Wanderdeckelkarde, are provided in which means for adjusting the Kardierraumes in its course over the working width, wherein the setting of the carding chamber in response to operating parameters or from a traveling lid position is variable.
- the traveling lids are influenced by means of a new device to the effect that by introducing at least one actuating force which acts directly on the revolving lid, a deformation of the revolving lid can be achieved.
- a setting force introduced by an adjustment device it is possible for a setting force introduced by an adjustment device to act on the revolving cover, which makes it possible to set the carding gap or carding space in the course of the working width on account of the manufacture and adjustment of individual components, changing operating conditions or else depending on the position of the revolving cover ,
- the manufacturing and adjustment data of a component or the changing operating conditions can be specified on the basis of operating parameters.
- Such operating parameters are, for example, the ambient conditions (temperature, pressure, atmospheric humidity), the properties and conditions of a component (temperature, production, wear), the properties of the material to be processed, or the achievable or current operating values (carding gap, carding quality).
- the adjusting device can be integrated into the traveling deck unit or mounted outside the drum shield.
- the revolving lids of today's revolving flat card are usually guided and stored on the so-called flexible arch on both sides of the drum.
- the flexible sheets are attached to the drum labels outside the working width corresponding to the width or axial length of the garnished portion of the drum.
- the revolving lids glide along the flexible bend along the circumference of the drum and span the drum over its entire working width between these flexible sheets or the bearing points.
- Carding machines used today have a working width of more than 1000 mm, usually more than 1200 mm, preferably 1500 mm.
- the new adjustment device will either integrated between the bearing points of the revolving lids or outside the bearing points or in the bearing points of the revolving lids themselves.
- At least one further guide of the traveling deck is inserted between the bearing points of the revolving lids.
- This guide allows an introduction of a force in the passing flat bar between its bearings.
- the guide is provided directly on the revolving lids, ie on the side facing away from the lid set side of the revolving lid.
- the revolving lids have in their construction a flange carrying the clothing and on the opposite side of the flange of the lid assembly on a protruding from this rib.
- the guide above the revolving lid causes a guide at the top, the lid set end facing away from the rib.
- the revolving lids have to be adapted in their construction to the additional stress or force transmission at the upper end of the rib. If there is only a single rib, this may possibly be reinforced by transverse ribs at the point where the force is introduced. When using lids made of hollow profiles, the hollow profiles may possibly be reinforced at the force application points.
- the actuating force which is transmitted from the guide to the revolving lid may be a mechanical, pneumatic or hydraulic force or a combination thereof.
- the actuating force is a magnetically acting force.
- An electromagnetically acting force is conceivable as a force. In this case, the actuating force can be adjusted by changing the electrical supply of the electromagnet.
- the transmission of a mechanical force in a rigid system from the guide to the revolving lid is only possible with contact of the guide with the revolving lid.
- guide surfaces are therefore to be attached.
- it is to pay attention to a pair of materials with good sliding properties such as a plastic-metal pairing.
- the guide surfaces on the revolving lids can be applied separately or already provided in the basic construction.
- the guide, which is mounted above the revolving lids and serves as a means of Dierraumes is provided and generated by its arrangement, a force on the revolving lid can be arranged movable.
- the guide itself is thus arranged adjustable. The adjustment can capture the guide as a whole or allow a segmental adjustment.
- the force acting on the revolving lid can thus be adapted to the position of the revolving lid. Since the force is mechanically introduced to the revolving lid means an adjustment of the guide in position at the same time an adjustment of the, acting on the revolving lid, force.
- all moving lids In order to ensure proper functioning of the mechanical introduction of force line, all moving lids must have a defined height at those points of the ribs where the guide is passed.
- the distance from the cover trim to the upper guide surface where the force is applied must be identical for all moving lids simultaneously used in the revolving flat aggregate.
- the design of this guide surface is dependent on the design of the revolving lid and is preferably to be designed by a mechanical processing or an accumulation of material. An accumulation of material can be done, for example, by pouring or sticking a leveling layer.
- a non-rigid mechanical system for example with a spring, would equate to the use of a hydraulic system for generating the actuating force.
- a hydraulic system for generating the actuating force.
- Such a system is able to exert a constant force on the revolving lid, even if they differ in height.
- the actuating force is generated by a pneumatic, magnetic or electromagnetic system. In this way, a non-contact transmission of the actuating force of the guide on the revolving lid is possible.
- the attachment of the guide or guides takes place in projecting into the moving lid unit or the traveling lid unit traversing rods or ribs.
- the attached in the revolving flat unit pulleys for the cover chain are supported by shafts, which are attached to both sides of the revolving flat mounted side shields.
- the side shields hold together the revolving flat unit.
- the side shields may be implemented as plates or as another suitable construction for receiving shafts.
- the attachment of the guide depends on its extent and number.
- the length of the guides can also extend from the cap inlet point to the lid outlet point.
- the lids are forced only in the places or positions in an additional upper guide, which require this to maintain a predetermined geometry of Kardierraumes. For example, at positions where the revolving flaps are moved vertically and thus the contours of the revolving lids are influenced by gravity or in places with a very high temperature.
- a magnetic force can be applied.
- stationary guide a first magnet and the revolving lid a second magnet is arranged.
- the revolving lid is characterized pushed away from the guide or pulled on the guide, without resulting in a mechanical contact between the guide and the revolving lid.
- the attached to the guide first magnet can be constructed of a plurality of individual magnets, which are spaced from each other.
- the second magnet arranged on the revolving lid can be dispensed with in favor of a magnetic material or built-in component, whereby in this design only a force attracting the one or more magnets can be exerted on the revolving lid.
- Such contactless guidance of the revolving lid has the advantage that no guide surface has to be formed on the revolving lid.
- the same adjustment device can be used for the entire guide or when using more than one permanent magnet for individual segments, as in the transmission of the mechanical force. But it is also conceivable to change the distances between the individual, mounted as the first magnet on the guide permanent magnets respectively to make adjustable, whereby the magnetic fields affect the moving lid mutually reinforce or cancel. By adjusting these distances, the magnetic force, which influences the revolving lid as a restoring force in its deformation behavior, can be increased or decreased.
- the guides on which the first magnets are mounted may be moved sideways.
- the overlap of the first magnets with the second mounted on the revolving cover magnet changes, which has a change in the force result.
- the actuating force is adjustable by changing an overlap of the first magnet and the second magnet by means of a displacement of the guide perpendicular to the direction of movement of the revolving lid.
- the magnetic force acting on the revolving lid can be changed by an electrical control.
- the arrangement of the electromagnets along the length of the guide and the arrangement of the guides Even within the traveling deck unit a more or less fine tuning of the actuating force can be achieved depending on the lid position as well as in the course of the working width.
- adjustments of the actuating force independent of the lid position are also conceivable, for example in order to be able to compensate misalignments in the production or uneven wear on machine elements or constructional differences between individual flat bars.
- means are provided which allow generating a force within at least one bearing point of the revolving lid. This is possible, for example, by rotating the bearing elements. In this case, a torque is applied to the revolving lid, which causes the lid deforms in a predetermined manner and thus causes a change in the Kardierraumes respectively the carding gap.
- a moment can be transmitted to the cover by means of a lever, which likewise causes a deformation of the cover and thus influences or alters the geometry of the carding chamber. If moments are introduced into the revolving lid on both sides of the revolving lid outside the bearing, the deformation of the revolving lid over the course of the working width can be influenced by an intentional difference between the moments. Only with identical moments on both sides is a symmetrical deformation of the traveling lid.
- the moment can be generated by a mechanical, hydraulic, magnetic or electromagnetic force.
- a change in the torque acting on the traveling lid as a function of the lid position can be achieved by mechanical or electrical means. It is also possible a combination of the described embodiments of a traveling decking unit according to the invention.
- a guide section can be installed in a stationary manner, wherein a further guide section is subdivided into individual segments, which can be adjusted independently of one another.
- the guides or guide sections are provided with an actuator system, as a further development of a simple mechanical adjustability.
- the actuators can be designed electrically or fluid-mechanically.
- the actuators make it possible to adjust the guide or sections thereof during operation and to adapt them to a current operating situation. For example, it is conceivable to automatically adapt the geometry of the carding chamber when changing over the product to be processed. Also, a coupling with a carding gap measurement is possible by the actuators. As a result, signs of wear can be compensated.
- the size of the force acting on the revolving lid actuating force is adjustable by the adjustment of the guides or the adjustment of the force itself.
- the setting of the size of the force can be controlled automatically.
- the size of the actuating force is controllable depending on the revolving flat position or independently thereof. Depending on whether several actuating forces are distributed over the working width of the card and generated at different positions in relation to the movement of the revolving lid.

- At least one electromagnet is installed in the revolving lid.
- the electrical supply can be carried out via sliding contacts.
- the electromagnet a magnetic field is built up, which in its strength depends on the power supply.
- the revolving lid to the drum is more or less strongly pulled.
- the revolving lid is deformed accordingly, which is reflected in a change in the geometry of the carding chamber.
- the installation location in the revolving lid can be done in the rib or in the flange. Also, installation in the clothing or behind a window attached to the clothing is conceivable to prevent interference with the magnetic field through the clothing or its construction.
- a controller can be installed in the revolving lid in addition to the electromagnet. This allows for a constant power supply of the revolving lid the ability to control or regulate the deformation of the revolving lid via signals. Such a control may be performed depending on various operating parameters or the revolving flat position.
- the signal transmission can also be done via sliding contacts.
- the magnets used can also be designed as a combination of permanent magnets and electromagnets. In this case, a constant magnetic field is maintained by the permanent magnet, which is more or less amplified by the electromagnet according to the current need.
- a permanent magnet movably mounted in the revolving lid can be used.
- the rotatably mounted permanent magnet is coupled to a mechanical device, for example a weight provided with a lever, which automatically effects a rotation of the permanent magnet by changing the position of the revolving lid relative to the horizontal.
- This rotation of the permanent magnet reduces or increases the strength of the magnetic field acting in the area of the drum and has the consequence that the force acting on the revolving lid changes correspondingly.
