Abstract:
A bobbin creel arrangement comprising:a bobbin creel (2) a four-bar linkage (4, 5, 6, 7) comprising a stationary member (4), adapted to be mounted on a machine frame of a textile machine, and moveable four-bar linkage members (5, 6, 7); wherein the bobbin creel (2) is connected to the four-bar linkage so as to be pivotable relative to the machine frame from a lower loading position into an upper operating position; at least one pneumatic cylinder (8) having a first end connected to the stationary member (4) and a second end connected to a first one (7) of the movable four-bar linkage members (5, 6, 7); wherein, for pivoting the bobbin creel (2) from the operating position into the loading position, the pneumatic cylinder (8) is a bidirectional pneumatic cylinder loadable at the first and second ends by compressed air; a pneumatic spring (9) having two ends and connected with the two ends to the four-bar linkage (4, 5, 6, 7), wherein the pneumatic spring (9) is tensioned when the bobbin creel (2) is pivoted into the loading position; wherein the stationary member (4) has a first pivot axle (4.3) and wherein the first moveable four-bar linkage member (7) has a second pivot axle (7.2), wherein the first and second ends of the pneumatic cylinder (8) and the two ends of the pneumatic spring (9) are connected to the first and second pivot axles (4.3: 7.2), respectively, wherein the pneumatic spring (9) extends substantially parallel to the pneumatic cylinder (8).
