Description
Technical Field
The invention belongs to the technical field of textile machinery, and particularly relates to a bobbin yarn suction nozzle positioning device.
Background
On an automatic winder, along with the increase of the diameter of a winding drum yarn, the contact relative position of the drum yarn and a grooved drum can deviate, and in order to ensure the consistency of the relative distance and parallelism of a suction nozzle and the drum yarn, a cam and a positioning sensor are driven by a rotating shaft of a support arm to form a linkage mechanism, so that the success rate of yarn searching of the drum yarn suction nozzle is ensured, and the efficiency of the machine is improved.
The existing bobbin yarn suction nozzle positioning device is characterized in that a cam curve track fixed on a rotating shaft of a support arm is used as a guide to push a connected sensor ejector rod, so that precise linkage contact is kept between all parts, the relative position of a suction nozzle and a bobbin yarn is always constant, and the principle is schematically shown in figure 1. However, in the rear holding arm structure, since the shape of the arm interferes with the position of the positioning lever in space, the forward direction direct movement of the cam cannot be realized, and therefore, the relative position between the suction nozzle and the cone yarn is constant by adopting the reverse cam structure.
In the Chinese patent literature, the invention name of the invention is a structural optimization cone yarn adsorption auxiliary system, and the invention patent with publication number of CN104555602A discloses a technical scheme, which comprises that one end of a driven push rod is tightly abutted against a cam curved surface, and the other end of the driven push rod is provided with a suction nozzle positioning sensor, so that the driven push rod can slide along the length direction of the driven push rod to enable the cone yarn suction nozzle positioning sensor to be close to or far away from the cone yarn suction nozzle, and the relatively ideal position between the suction nozzle and the cone yarn surface is achieved through improvement of the cone yarn suction nozzle instead of the improvement of a positioning device.
Disclosure of Invention
In order to solve the technical problems, the invention provides a bobbin yarn suction nozzle positioning device which has the advantages of compact structure, accurate transmission distance and capability of effectively avoiding interference between a positioning rod and a support arm in a limited space.
The technical scheme of the invention is as follows:
a positioning device of a cone yarn suction nozzle comprises a support arm for holding cone yarn, a positioning rod for positioning the cone yarn suction nozzle, wherein a positioning sensor is arranged at the end, close to the cone yarn suction nozzle, of the positioning rod, and the other end of the positioning rod is movably arranged on a bracket; the positioning rod is connected with the support frame through an elastic component, and the positioning rod is connected with the support frame through an elastic component.
Compared with the prior art, the positioning device is designed based on the conception of the curved motion of the reverse cam, the diameter of the cone yarn is increased, the rotating shaft of the support arm moves, and the positioning swing rod combining piece is synchronously driven to act, so that the swing rod cam swings back and forth along the reverse contact curved track, namely around the rotating center, the positioning rod is pushed to move forward by the vertical surface of the swing rod cam, the synchronization of the positioning stop position of the cone yarn suction nozzle and the lifting position of the support arm for winding the cone yarn is realized, and the consistency and the parallelism of the space between the cone yarn suction nozzle and the cone yarn position are ensured. For the forward cam curve, the center line of the positioning rod can ensure good transmission performance through the rotation center of the cam, and the point of the positioning rod contacting the cam track must be small, so that the positioning rod can walk along the track without distortion. In the technical scheme, the force application direction passes through the center of the positioning rod, but the center of the positioning rod does not need to pass through the center of the cam, the positions can be staggered in a limited space, and the sharp point of the positioning rod contacting the cam vertical surface of the swing rod is not too small.
Based on the scheme, the invention also makes the following improvements:
the elastic component is a spring sleeved on the positioning rod, and the spring is in a compressed state. Under the action of spring force, the positioning rod always keeps close contact with the vertical surface of the swing rod cam, and the curve side of the swing rod cam is forced to be always pressed on the cylinder of the positioning rod combining piece. The reverse curve track of the swing rod cam always keeps close contact with the small cylinder of the positioning swing rod connector, and under the condition that the support arm rotates, the positioning rod and the front sensor are synchronously and positively pushed to act by the vertical surface of the swing rod cam, so that the synchronization of the positioning stop position of the cone yarn suction nozzle and the lifting position of the cone yarn of the support arm is realized.
The swing rod cam is provided with a curved surface, and the positioning swing rod combining piece is matched with the curved surface through a cylinder so as to drive the swing cam to move. In the improvement scheme, the rotation center of the swing rod cam is placed at the lower end of the swing rod cam through the design of the curve surface and the cylinder, the rotation center of the support arm is not relied on, the arc track of the rotating shaft of the support arm can be indirectly transferred to the curve surface of the swing rod cam through changing and positioning different shapes of the swing rod combining piece in a narrow and non-interference space, the interference of the support arm is avoided, the cylinder is in contact with the curve track of the cam, and the abrasion loss is reduced.
The radius of the cylinder is smaller than the minimum radius of curvature of the curved surface. In order to ensure that the motion curve track is not distorted, the track of the cam is obtained according to the position of the bobbin yarn change and cannot be simply smaller, if the position of the cylinder on the swing rod combination piece is changed, the change of the radius of the swing rod combination piece is equivalent to the change of the radius of the swing around the rotating shaft, and the smaller the radius of the cylinder is, the better the smaller the cam track is.
The positioning swing rod combining piece is positioned and assembled with the support arm rotating shaft through the flat hole. In the improvement scheme, the initial installation position of the empty bobbin of the bobbin yarn is ensured through the positioning assembly of the processing flat surface of the hole and the rotating shaft of the support arm, and the positioning pin is not required to adjust the assembly.
The tail end of the support arm is provided with an interference part protruding towards the direction of the positioning rod. The technical scheme is that whether the support arm is provided with an interference part or not and the protruding direction of the interference part are determined according to the specific space in the equipment in order to avoid the interference of the positioning rod and the support arm in the limited space.
The side bracket is fixedly arranged on the box body frame.
