Definitions

• the invention relates to a thread brake of the type specified in the preamble of patent claim 1, and to a method according to claim 29 or 30.
• the cover can be slightly lifted off the fixed braking surface parallel to itself by means of two links against spring force against adjusting axes perpendicular to the thread travel path and parallel to the fixed braking surface. Since the cover covers the braking zone in the raised position, neither free access nor unobstructed view is possible.
• the disc is fixed to an axis that is fixed in the housing and cannot be rotated, and is preloaded against the fixed braking surface. The braking zone cannot be exposed.
• the cover can be slightly adjusted with two C-shaped links around adjusting axes parallel to the fixed braking surface. Since the braking zone is not fully exposed, unhindered access and free view are not possible.
• the thread brake is equipped with a compressed air cleaning system on the cover or on the brake housing, which directs air jets into the braking zone at right angles to the thread running direction.
• Thread brake for a rapier weaving machine known from US Pat. No. 6,161,595
• the brake plate is constantly pressed against the fixed braking surface by a helical spring supported with a portal-like superstructure, and additionally controlled by magnetic force depending on the web cycle.
• Thread brakes constructed in accordance with US Pat. No. 6,161,595 and used in practice have compressed air channels leading to connections in the housing.
• the blow-out nozzles open freely on the side of the brake gap defined between the brake plate and the brake surface. This affects cleaning efficiency and high compressed air consumption.
• the thread brake should be able to be cleaned efficiently with compressed air from lint which settles in the area of the braking zone.
• the known thread brakes do not meet these requirements in practice satisfactorily.
• the invention has for its object to provide a thread brake of the type mentioned, which is dictated by the requirements dictated by practice with regard to quick to manufacture, unimpeded access or insight into or into the braking zone and / or compressed air cleaning in a structurally simple manner.
• the hinged lid which can be opened on one side, not only lifts off the braking surface when it is opened, but also moves far away from the fixed braking surface with its freely projecting end area. This completely exposes the braking zone and gives both unhindered access to and full view of the braking zone. This means that the fixed braking surface and its surroundings are just as accessible as the braking plate and its surroundings on the hinged cover.
• the hinged lid can be opened and closed again quickly, so that no appreciable downtime of the peripheral devices of the thread brake is necessary for a check or the like. Handling is extremely convenient. The construction effort for this comfort function is low.
• the positioning axis is expediently approximately parallel and laterally offset with respect to the fixed braking surface to the thread travel.
• the hinged cover swings up and out of the braking zone completely. Access to the braking zone is possible from all sides, and especially from above.
• the positioning axis can be arranged at least approximately parallel to the braking surface and approximately perpendicular to the thread travel.
• the opened hinged cover releases the entire braking zone. If the positioning axis is also offset from the thread path, e.g. up, then there are even more convenient access options.
• the actuating axis can be arranged on the inlet side or on the outlet side of the fixed braking surface.
• the actuating axis is designed as a hinged-lid hinge in the housing.
• the hinged cover with offset actuating axles is connected to two handlebars of different lengths via a handlebar mechanism. This leads to a precisely controlled opening movement of the hinged cover, which moves laterally or longitudinally away from the braking surface when opening.
• the thread brake is compact when the hinged cover is sunk in the closed position between the thread guide elements fixed to the housing.
• the hinged lid shields in the In the closed position, the braking zone is closed to the outside. When the hinged lid is open, the entire braking zone is freely accessible.
• An opening angle of the hinged cover greater than 90 ° is advisable because it allows access to the braking zone from all sides.
• An opening angle of almost 180 ° is particularly practical, e.g. about 150 °.
• a positioning device enables a high level of operating comfort at least for the closed and / or the unfolded position of the hinged lid.
• the opened hinged lid does not need to be held on. In the closed position, it has the position that is advantageous for the correct operation of the brake plate.
• the positioning device has a snap lock and stop surfaces for the hinged lid.
• pin anchors are attached to the hinged cover and oriented approximately perpendicular to the thread travel. With pin anchors on the inlet side, the brake plate is dragged in the closed position of the hinged cover and held and positioned to move independently.
• the brake plate can have open cutouts on its longitudinal edges, in which the pin anchors engage.
• the open suspension cutouts are expedient in terms of production technology and facilitate the replacement of the brake plate, because the appropriately thickened pin anchors need not be dismantled.
• At least one spring can be provided between the underside of the hinged cover and the brake plate.
• the spring In order to prevent the brake disc from fluttering while the thread is running and the electromagnet is not under pressure, the spring should consist of damping material. such as polyurethane, foam, elastomer or a dead rubber material, or at least contain a damping insert made of a damping material.
• the spring generates the load necessary for the basic braking effect, but allows the self-actuating or venting movements of the brake plate in relation to the braking surface, which are advantageous especially for cleaning the compressed air. It dampens oscillating movements of the brake disk induced by the thread running during the basic braking effect.
• the spring can be an S-shaped polyurethane lip that extends approximately over the width of the brake plate.
• the hinged lid should be made of non-magnetic material such as light metal or plastic so that it does not consume electromagnetic power.
• the thread brake should be equipped with a pneumatic cleaning device to prevent malfunctions due to the accumulation of dirt or lint.
• At least one nozzle that can be pressurized with compressed air can be discharged from outside the braking zone, e.g. be directed to the inlet side between the thread guide element and the braking zone.
• a throttle gap which is expediently limited by a wall approximately perpendicular to the braking surface and the brake plate itself small that there is no contact between the brake disk and the wall can enter, but on the other hand, as little compressed air as possible can flow out to the outside unused. Thanks to the throttle gap, a major part of the compressed air acts on the braking zone, so that even low levels of compressed air can be used to effectively remove critical contaminants.
• the cleaning effect can be intensified by arranging a number of nozzles along the longitudinal edge region of the braking zone, the multiple nozzles having relatively small outlet cross sections for efficient use of the compressed air.
• the brake plate delimiting the throttle gap can be widened with respect to the braking surface.
• a nozzle is expediently mounted in at least one cheek of the thread brake containing a thread guide element, the blowing direction of which is aimed at the brake gap, approximately parallel to the thread path and in the plane of the braking zone, offset laterally with respect to the thread path.
• the compressed air from the nozzle acts on the braking zone next to the thread travel path in the braking zone, where contaminants collect, while the thread travel path is kept free by the thread itself.
• the nozzle can be installed directly in the thread guide element.
• the thread guide element can form an exchange part with the mounted nozzle, which is replaced by a conventional thread guide element if the thread brake is to be equipped with a pneumatic cleaning device.
• the nozzle in the outlet-side cheek expediently works with a blowing direction opposite to the thread running direction. This means that impurities on the inlet side are blown away particularly effectively and are not conveyed through the entire braking zone.
• the nozzle is connected to a solenoid valve which is connected to an actuation control device.
• the actuation control device activates the nozzle at the optimum time in each case, for a desired period of time and, for example, with a desired intensity.
• the actuation control device is expediently connected to a control device of the thread brake and / or the control device of the weaving machine in order to control a cleaning cycle when the thread brake is deactivated and the thread is at a standstill.
• the solenoid valve may even be controlled directly by the control device of the control brake or the control device of the weaving machine.
• several thread brakes in a thread processing system with their pneumatic cleaning devices can be connected to a common solenoid valve, although a solenoid valve for each thread brake or a solenoid valve on each thread brake is to be preferred because the thread brakes are deactivated at different times.
• a cleaning cycle is best carried out when the thread is stopped when the shed is closed and lasts a maximum of time until the thread starts to run again. It is not necessary to clean between two entries at each break, but it may be sufficient to carry out a cleaning cycle only after a certain number of entry processes.
• the cleaning cycle can take place in such a way that compressed air is permanently blown out, or alternatively with compressed air pulses.
• the actuation control device expediently has a programming section with which the cleaning cycles can be set in each case as a function of deactivation cycles of the thread brake and / or the work cycles of the weaving machine.
• the nozzle with the solenoid valve and a compressed air connection between the nozzle and the solenoid valve form a kit that can be mounted or mounted on the thread brake. If the thread brake is equipped with mounting devices for the kit from the outset, it is possible to retrofit the thread brake to a thread brake with a pneumatic cleaning device at any time.
