Embodiment Construction
[0033] refer to figure 1 As shown, the edge stroke control system of the present invention with a random spinning grading range includes a yarn drum 1 for winding spinning and a reciprocating yarn guiding mechanism 2. The reciprocating yarn guiding mechanism 2 includes a yarn guiding body 21 and a The wire guide 22 on the wire guide body 21 that laterally moves and guides the lead wire, also includes an edge controller for edge control of the winding spinning, and a reciprocating guide for linking the wire guide body 21 and the wire guide 22 to produce offsets. The rod 3 and the driving mechanism for driving the reciprocating guide rod 3 to move, the edge controller is connected to the reciprocating guide rod 3 through the driving mechanism, and drives the guide wire body 21 and the wire guide 22 in the guide wire body 21 to generate a transverse direction. Superimposed offset, by controlling the offset and superposition of the guide wire body and the wire guide, the edge retr...

The invention discloses an edge stroke control system and a method with a random spinning grading range. By superimposing a random offset on the edge retraction stroke, the edge retraction stroke is divided into grades, and the reciprocating point of the stroke is at It is evenly distributed within the grade range, so that the winding density of the end face of the package can be properly compensated, avoiding the generation of shoulders, and a random offset is superimposed on each grade, which can effectively avoid the mechanical inertia due to forward and reverse switching. Therefore, the invention can effectively prevent the convex shoulder, eliminate the convex edge phenomenon, and improve the forming quality of the package. Under the high-speed unwinding of the subsequent process, the occurrence of broken ends and loops can be greatly reduced. It can be used for the regular traverse of the reciprocating guide rod of the reciprocating wire guide mechanism of the spinning machine, and is suitable for the edge stroke control of the winding mechanism of the cylindrical package of any linear material.
Description
technical field [0001] The invention relates to the technical field of spinning machinery control, in particular to an edge motion control system and a method thereof with a random spinning grading range. Background technique [0002] The chemical fiber filaments are wound into cylindrical packages on the spinning machine. During the packaging process, as the winding diameter increases, the winding density on the end face of the package is higher than the winding density in the middle of the package. If no treatment is done, a shoulder wire will be formed, which will cause the vibration of the winding mechanism. , damage the forming of the package, and it is prone to breakage and de-looping during subsequent unwinding. In order to prevent the occurrence of shoulders, there are various edge stroke treatment methods available, such as: groove rail stroke correction method, screw stroke correction method, graded stroke correction method, etc. Process method to correct the coi...
