«Machine assembly with a new material handling mechanism in the sewing machine»

Download an article

The paper presents the dynamic model of the machine assembly with a recommended mechanism for moving material and the definition of the law of rails motion under various system parameters. The author has suggested the solution implemented by the system of differential equations numerically on the PC and the system describing the motion of the machine set. Recommended values ​​of the parameters of elastic links of material transfer mechanism have been obtained. The researcher has developed the methods of kinematic and dynamic analysis of the material transfer mechanism with elastic elements of the sewing machine and has approved the parameters and development of the design.

«Mechanism of material movement and its description»

Download an article

The article provides the kinematics chart of mechanism of material movement of sewing machine and determination of law of lath motion at the different parameters of the system and its equalization. It also determins concrete values of linear speed of point Е of lever – laths at moving of material in sewing machines. A mechanism is worked out with the storage of energy as a conical spring, that operates at the horizontal moving of lath and a mechanism is executed as the reserved kinematics chain.
