Abstract
L'invention concerne un appareil de stockage de fil destiné à alimenter en fil un appareil consommant du fil. Ledit appareil de stockage comprend un corps de stockage comportant un alésage dans lequel on stocke du fil, ledit alésage comportant une ouverture de décharge de fil à une extrémité et une ouverture d'insertion de fil à son extrémité opposée, ainsi qu'un moyen de chargement de fil permettant l'insertion de fil dans l'alésage. Ledit moyen de chargement de fil comprend un guide fil rotatif placé à l'intérieur de l'alésage, lequel lors de la rotation décharge des bobinages de fil dans l'alésage pour créer un corps compact de fil enroulé, augmentant progressivement en longueur sur la longueur de l'alésage pendant la rotation du guide fil.The invention relates to a wire storage device for supplying wire to a wire consuming device. The storage apparatus includes a storage body having a bore for storing wire, the bore having a wire discharge opening at one end and a wire insertion opening at its opposite end, and means for wire loading allowing insertion of wire into the bore. Said wire loading means comprises a rotary wire guide placed inside the bore, which upon rotation discharges the wire windings into the bore to create a compact body of coiled wire, gradually increasing in length over the length of the bore during rotation of the wire guide.
Description
An alternative construction of loading disc 6 is illustrated in Figures 4 and 5 wherein the disc 6 has a rotatable end wall portion 80 defining the abutment face 37. Accordingly, during loading of yarn, the abutment face 37 remains stationary as the disc 6 rotates and thereby avoids resistance to rotation of the disc 6 caused by engagement with the yarn compact body 40. The embodiment illustrated in Figures 4 and 5 also includes a yarn retention means 90 located adjacent the insertion opening 24 for resisting inadvertant removal of yarn and thus collapse of the compact body on removal of the yarn loading means 30. In the illustrated embodiment the yarn retention means 90 comprises a resilient stirrup member 91 conveniently made from bent spring wire which in a relaxed condition extends into the interior of the tube. The disc 6 is preferably rotatably mounted in a collar 92 which on insertion into the tube deflects the stirrup member 91 to a stowed position during yarn loading. <Desc/Clms Page number 5> The embodiment of Figures 4 and 5 also includes a yarn winding restriction means 100 which is located upstream of the loading disc 6 and serves to restrict the crosssectional size of the compact body to be extruded along the tube downstream of the restriction means without causing excessive resistance at the yarn loading means created by sliding resistance between the compact body and the internal walls of the tube. The restriction means 100 preferably comprises one or more restriction members 103 which project into the bore of the tube to provide a restricted opening. The restriction members 103 may be of a resilient nature or may be rigid. It assists the even formation of coils in the bore if the yarn loading means includes a yarn retraction means 50 which intermittently engages the yarn in its passage from the feed device 12 to the disc 6 so as to alternately pull back and release the yarn as shown. When the yarn is pulled back, the coil formed is tightened and thus pulled to the centre of the bore. When the yarn is released, the yarn forms coils at the inside walls of the bore. The retraction means 50 is preferably in the form of an eccentric disc or cam 13 mounted on a rotatable shaft 14. The disc <Desc/Clms Page number 6> eccentricity and the relationship between the speed of shaft 14 to shaft 8 can be designed to give the coil formation in the tube which gives the maximum stored length of yarn. When the fabric forming machine is in operation, there will always be yarn in the bore for disc 6 to push against to start winding. However, when first installed, additional means need to be provided to get the coil formation to start. This may be in the -form of a bung 16 ( Fig 3 ) resiliently pressed against the bore wall by typically a leaf spring 17. The bung is pushed along the tube as winding proceeds and can be taken out of the front end before transferring the front of the yarn to the fabric forming machine. Alternatively a resistant bung may be provided formed for instance from a body of resilient material such as for example a body of foam plastics material. Once initially set up, the yarn need never be rethreaded to the fabric forming machine. It is envisaged that an array of tubes 1 could be associated with say a weaving loom, an individual tube 1 serving to supply a warp yarn to the loom. A single yarn loading means may be provided which is movably mounted so as <Desc/Clms Page number 7> to be able to be positioned for loading yarn into any one of the tubes forming the array of tubes. Sensing means may be provided associated with each tube and arranged to provide a signal when a predetermined quantity of yarn is left in the tube. The signal can be used to automatically cause the loading disc 6 to be moved to load fresh yarn into the appropriate tube. It is envisaged that the loading disc 6 may be controlled by programmable control means which can be programmed to automatically move the loading disc 6 to selected tubes and load a predetermined colour into the selected tube. <Desc/Clms Page number 8> CLAIMS 1. A yarn storage apparatus for supplying yarn to a yarn consuming apparatus, the storage apparatus comprising a storage body having a bore in which yarn is stored, the bore having a yarn discharge opening at one end and a yarn insertion at its opposite end, a yarn loading means for inserting--yarn into the bore, the yarn loading means including a rotatable yarn guide located within the bore which on rotation discharges windings of yarn into the bore to create a compact body of coiled yarn, which progressively increases in length along the length of the bore during rotation of the yarn guide. 2.
