Automatic splicing and active deviation rectifying system of wirecord fabric cutting machine

Abstract

The invention discloses an automatic splicing and active deviation rectifying system of a wirecord fabric cutting machine. A deviation rectifying and splicing device comprises a connector splicing machine and a connector feeding machine which are arranged front and back in a wirecord fabric conveying direction, the rear portion of the connector feeding machine is hinged, and the front portion of the connector feeding machine is provided with a deflection mechanism which drives a machine body to swing under the control of a PLC. An edge sensor I is arranged on the connector feeding machine andsenses edges of the front portion and the rear portion of a cut cord fabric in a non-contact manner. An edge sensor II is arranged on the connector splicing machine on the front side of a splicing position and senses the edge of the rear portion of a spliced cord fabric in a non-contact manner. The deflection mechanism adjusts the connector feeding machine according to feedback information of theedge sensor I and the edge sensor II so as to align the front edge of the cut cord fabric with the rear edge of the spliced cord fabric and return a drifted tail edge of the cut cord fabric to a cutting datum line. According to the device, connector precision of the cord fabric can be greatly improved, unqualified joints caused by large and small ends of the cord fabric are reduced, and unattendedintelligent splicing is realized.

Description

technical field [0001] The invention relates to tire component production equipment, in particular to an automatic splicing and active deviation correction system for a steel cord cutting machine. Background technique [0002] Steel cord refers to the tire parts covered with rubber on the steel cord. On the cord calender, the steel cord is covered with rubber to form a steel cord roll. The steel cord roll is cut on the steel cord cutting machine according to different angles and widths. The cut cord The shape is a parallelogram with a certain angle and width; in order to achieve the continuity of tire building, the small-angle steel cord cutting machine is designed with a joint device, which connects the cut cord strips in a direction parallel to the steel wires (the beginning and end of each parallelogram cord connected), and then coiled for use in the forming machine. [0003] Steel cord is used as the skeleton of the tire, and its angle, width continuity and uniformity a...

Problems solved by technology

[0004] The steel cord of the tire is a thin sheet, with a certain amount of viscous material and a certain degree of softness. It sticks to the knife during cutting, and its position will change during blanking. It is also a common problem that the tail of the cord deviates from the cutting line (reference line) when the cord is conveyed.

[0005] The current small-angle steel cord automatic jointing device mainly realizes the automatic edge alignment of the joint through manual calibration of the knife edge line and discharge line, but the accuracy guaranteed by this method depends entirely on the operator's operating skills and level
