Definitions
- the invention relates to a thread brake with two resiliently pressed against each other by load means disc or plate-shaped brake elements, between which at least one thread to be braked can be carried out and of which at least one braking element is a central one Has opening.
- Such so-called disc or plate thread brakes are in various forms in textile technology in use. Particularly advantageous, modern constructions are described, for example, in DE 41 04 663 C1 and in DE 43 01 507 C2, both to the applicant go back. They have pin-shaped storage means throughout on through the central opening at least one Braking element are arranged and on which at least this one braking element is rotatably mounted. There are embodiments in which the diameter a bearing pin forming the pin-shaped bearing means is much smaller than the diameter of the middle Opening the brake elements so that they swing freely are hung from the bearing pin. Other embodiments use pin-shaped storage means that are in the form of a Bolts are formed, the diameter of which is only slight is smaller than the opening diameter of the brake elements (compare, for example, FIG.
- the brake elements with plastic bearing bushes are their storage conditions on the bolt or a ceramic bearing bush pushed onto this improve.
- the brake elements are elastic against each other oppressive burden means are either after conventional type compression springs or there are too permanent magnetic rings are used for this purpose cup-shaped, made of ferromagnetic material existing brake elements are inserted.
- Thread guide means provided, as a rule at least partially directly on the mounting means are provided which the bearing pin or bolt for carry the braking elements.
- the arrangement is mostly hit such that the bearing pin or pin on the Bracket is overhung.
- the braking elements such as mentioned, oscillating on a bearing pin of small diameter are suspended, the braking elements at a distance assigned lateral stop elements that otherwise limit and prevent free movement in the axial direction, that the brake elements are released from their bearing means.
- the holder means with which the thread brake, for example. is attached to the housing of a thread delivery device, are consistently designed to be relatively complex applies in particular if the thread brake with a Vibration generator cooperates, which the Brake elements set in vibratory movements, the are mainly directed transversely to the bearing axis (DE 41 04 663 C1) or in a direction perpendicular to it act (DE 44 09 450 C2). Because of the braking elements or their bearing means vibrated the lint deposits that otherwise occur, Soiling, etc., originating from difficult to process Yarns can be largely prevented. The The measure has therefore proven itself in practice proven.
- Thread brakes of the aforementioned type are fundamental Bulk items, which means manufacturing costs crucial for the economic Success comes. They also have to be easy to maintain and in particular, to be cleaned, what usually through Blowing off by means of a compressed air jet happens.
- the braking elements from their Free storage materials or that have blown off Dirt particles, lint and the like in corners or blind spots of mounting elements, bearing parts, etc. accumulate the thread brake and thus in the long run Endanger operational safety.
- the object of the invention is therefore a thread brake to create oneself with simple, inexpensive Construction due to few dirt deposits distinguished and easy cleaning, as well as necessary disassembly and assembly of your parts allowed, while at the same time a perfectly even Braking of the thread guaranteed over long operating periods is.
- the holder means on the new thread brake for which the disc or plate-shaped brake elements bearing, pin-shaped bearing means essentially one U-shaped bracket with two spaced apart on both sides of the brake elements trending thighs on one that is preferred Embodiment is a one-piece wire bent part.
- the pin-shaped bearing means are attached to this bracket a bearing part which preferably accommodates them on both sides attached that connected to the stirrup legs or on this is trained.
- This bearing part can be in one preferred embodiment in the form of an essentially U-shaped frame and made of plastic be.
- the bracket can be two parallel to each other Have bracket sections with which he in a receiving part is stored at a suitable location on a Machine frame or the like but also on the housing a thread delivery device can be attached.
- the Temple sections can be moved longitudinally in the receiving part be stored, which is particularly important is when at least one of the bracket sections for coupling with a back and forth oscillating motion of the bracket issuing vibration generating device is set up. In this way, as already mentioned, effectively prevents the deposition of fluff, etc. become.
- this can be the pin-shaped bearing means receiving bearing part designed to be removable from the bracket so that the bearing means together with the bearing part to be able to exchange.
- the bearing part can the bracket can also be arranged adjustable, for example To facilitate cleaning of the thread brake or around the To change thread travel.
- the bearing part as a U-shaped Frame formed, so the frame on the bracket between an operating position and a folded down position Position pivotable and in the operating position on the Bracket can be designed lockable.
- the one in the correct position on the bracket found frame only needs to be folded down be accessible to the pin-shaped storage means to make them blown off on all sides or otherwise can be cleaned.
- the pin-shaped storage means on the frame i.e. more generally on the bearing part, releasably attached, so they can with the frame folded down simply removed and replaced.
- the thread brake can also be designed so that the whole frame with the bearing means and the brake elements can be replaced without the bracket or others Parts of the thread brake are removed or disassembled would have to. Folding down and, if necessary, removing the Framework, as well as the exchange of storage resources done without the help of tools.
- the bearing pins a much cheaper support the pin-shaped storage means guaranteed. This allows it with straight bearing pins of relatively small diameter to find the end of it without also having to Vibration exposure by a vibration generating device accepted an increased risk of breakage should be. Since these bearing pins usually consist of one hard material, for example ceramic, hard material and the like exist and are relatively expensive achieve a significant price advantage in this way. Other developments of the new thread brake are the subject of subclaims.
