Definitions
- the invention relates to a device for storing thread-like material which can be pulled off a supply spool, e.g. Weft yarn, wire, ribbon etc., in particular on a weaving machine, with a winding body, which has a supporting part arranged around an axis of rotation and a substantially cylindrical winding drum arranged thereon and having a central axis, as well as a number of circumferential elements radially adjustable to the winding drum for guiding the contains thread-like material that can be stored in a single-layer winding on the circumference of the winding body and can be pulled off the winding body in the axial direction.
- a supply spool e.g. Weft yarn, wire, ribbon etc.
- the winding drum is mounted eccentrically with respect to the axis of rotation in the edge region of a support disk which is rotatable about the axis of rotation or, in another embodiment, secured against rotation.
- Different winding diameters can be set in accordance with the respective radial position of the peripheral elements, which each determine a polygonal to approximately circular guideway for the thread-like material to be stored with a peripheral portion of the winding drum.
- the one corresponding to the largest winding diameter runs Guide track essentially concentric to the axis of rotation, while the guide tracks corresponding to the smaller winding diameters run eccentrically to the axis of rotation.
- the increasing eccentricity of the thread winding in accordance with the decreasing winding diameter can lead to discontinuous stresses and thus to voltage fluctuations in the section of the thread-like material running from the supply reel to the winding former, particularly in the case of the small winding diameters.
- the invention has for its object to provide an improved in this respect, further developed device of the type mentioned, which allows a continuous, gentle removal of the thread-like material from the supply spool.
- winding drum is fastened to the support part so as to be adjustable transversely to the axis of rotation.
- the peripheral elements in each position of the winding drum that is eccentric with respect to the axis of rotation, can each be set in a radial position relative to the winding drum in which their peripheral parts with respect to the central axis of the winding drum, which lie in a plane perpendicular to the central axis, and the In the same plane, circumferential part of the winding drum lying furthest away from the axis of rotation, determine a circumscribed circle concentric to the axis of rotation, the diameter of which can be freely adjusted between the limits given by the corresponding dimensions of the supporting part and the winding drum.
- This arrangement ensures for all winding diameters an essentially constant, particularly low stress on the thread material and is therefore particularly suitable for processing delicate thread material.
- the winding drum can be pivotably articulated on the support part about a pivot axis arranged offset with respect to the axis of rotation and with respect to the central axis of the winding drum and can be fastened adjustably about this pivot axis.
- the pivot axis of the winding drum is offset by the same amount with respect to its central axis and with respect to the axis of rotation.
- the winding drum alone can also be adjusted concentrically to the axis of rotation of the winding body without using circumferential elements, so that even with the smallest winding diameter of the winding body given by the diameter of the winding drum, the winding of the filamentary material to be stored is ensured with essentially constant tension.
- a device in a particularly compact, reliable construction can be achieved in a further embodiment of the invention by providing at least two holding parts which are offset against one another on the end face of the winding drum and act against one another around the central axis thereof and can be braced against the supporting part.
- the winding diameter of the winding body can be adjusted in a particularly simple manner and also continuously over the entire adjustment range in that the support part contains at least two guide slots formed on its end face facing the winding drum for guiding one of the holding parts each.
- the setting of the winding diameter can be facilitated by the fact that the guide slots are formed in a circular arc and are arranged concentrically to the pivot axis of the winding drum.
- the guide elements can be positioned opposite one another in the winding drum the axis of rotation of the winding body offset shaft can be driven, which is connected to a drive shaft determining the axis of rotation of the winding body adjustable relative to this.
- a particularly compact design with a relatively small dimension of the device in the axial direction can thereby be achieved according to one embodiment of the invention be that the support part on its end facing the winding drum contains a recess corresponding to the range of motion of the rotating body adjustable with the winding drum, which is suitable for receiving a section of the peripheral part of the rotating body which can be inserted into the area of the supporting part.
- the thread store 1 contains a fixed housing 2, which is fastened with a foot part 3 on a carrier part 4 of a weaving machine or a bobbin frame.

- the drive body 6 rotates with the gear 23 and the guide tube 9 according to arrow 38 about the axis of rotation 8, the entry end of the guide tube 9 always remaining in the region of the axis of rotation 8.
- the weft thread 12 running from the outlet end of the guide tube 9 is placed on a relatively strongly conical peripheral portion 15b of the winding drum 15 in thread turns. These are then pushed to the right by the teeth 36 of the star wheel 33 driven by the shaft 25 over the essentially cylindrical or, as shown, weakly conical peripheral portion 15c of the winding drum 15 in FIG and deducted in batches over the head end 15a of the winding drum 15 during the weft insertion.
- three circular arc-shaped slots 41, 42 and 43 can be formed in the base plate 14, which are arranged offset to one another in the circumferential direction concentrically to the axis 24.
- the screws 26 engaging on the winding drum 15, each arranged in a guide sleeve 44 are guided, which corresponding pivoting of the winding drum 15 about the axis 24 and thus different settings of the winding drum 15 transverse to the axis of rotation 8 on the base plate Allow 14.
- the base plate 14 is also provided on its end face with a recess 45 which receives a portion of the peripheral part of the star wheel 33 which projects into the region of the base plate 14, the shape of the recess 45 being the pivoting range of the star wheel which can be pivoted about the axis 24 with the winding drum 15 33 is adjusted.
- concentric annular grooves can be formed or, as indicated in FIGS. 2, 3, 4 and 5 by dash-dotted lines, corresponding concentric marking circles 46, 46a, 46b, 46c can be attached, which are for guiding or for easier adjustment the peripheral elements 18 serve with respect to the base plate 14.
- the winding drum 15 is - with loosened screws 26 - by pivoting about the axis 24 of the shaft 25 relative to the fixed base plate 14 between the operating position shown in FIG. 2, central with respect to the axis of rotation 8, and one shown in FIG. 5, with respect to the Axis of rotation 8 eccentric operating position 15 "ver adjustable, in which the edge of the winding drum 15 resting on the base plate 14 touches the largest marking circle 46 running along the edge of the base plate 14.
- the screws 26 guided in the slots 41, 42, 43 are each adjustable between the position shown in FIG. 3 and a position 26 ′′ according to FIG. 5, so that the winding drum 15 can also be fastened in any position within the Eccentric operating position is guaranteed.
- 4 shows a middle operating position 15 ', in which the edge of the winding drum 15 is set to the smaller marking circle 46b and the screws 26 each assume a corresponding position 26'.
- the guide bracket 20 is attached to the housing 2 by means of screws 51. 2, 4 and 5, the screws 51 can be arranged on the guide bracket 20 in slots 52 extending transversely to the circumference of the housing 2 and guided in the circumferential direction on the housing 2 in a circular arc-shaped guide slot 53 concentric with the axis of rotation 8 and can be locked be.
