Title:
ROTARY POSITIONING MECHANISM OF COP CHANGER OF SPINNING FRAME
Document Type and Number:
Japanese Patent JP3147625
Kind Code:
B2
Abstract:
PURPOSE: To prevent the exertion of excessive force on a moving member of a driving means by the force generated by the contact of a contacting part formed on a piston rod of a driving cylinder with a stopper member and minia turize an attaching bracket for holding the driving means.
CONSTITUTION: A fine spinning frame is provided with a driving cylinder 29 for rotating the whole pantograph mechanism by the expansion or contraction of a piston rod 30 via a transmission mechanism. The piston rod 30 has a contact face 35a and the driving cylinder 29 is provided interposing an attaching bracket 36 with a stopper cylinder 38 having a piston rod 39 movable in the direction perpendicular to the axial direction of the piston rod 30. A stopper 44 is attached to the piston rod 39 via a bracket 41. The stopper 44 is brought into contact with the contacting face 35a by properly driving the piston rods 30,39 to position the piston rod 30 at the intermediate stroke position and the pantograph mechanism at the intermediate position.
