Description

Floating type clamping mechanism for taking hat brim

Technical Field

The utility model relates to a floating brim of a hat fixture field technique of getting especially indicates a floating brim of a hat fixture of getting, and it is main but not the restriction is applied to brim of a hat sewing machine.

Background

In the morning, for sewing of semi-finished products such as a hat brim, a shoe tongue and the like, manual feeding is generally adopted, namely: manually putting one brim to the machine head at one time, taking out the brim after sewing, and manually taking out the second brim by an operator to put the brim in the machine head. The operation mode limits the processing efficiency, at least one machine is needed for one operator in personnel configuration, so that the labor cost consumption of a processing manufacturer is high, and meanwhile, due to the reasons of manual errors and the like, the stability and consistency of the processing quality are difficult to ensure, and the high processing requirement of a product is difficult to meet.

Later, automatic feeding devices were developed, which take the material piece by an automatic manipulator and feed it to a table of a sewing machine for sewing. The common manipulator for taking the cap peak is of a sucker structure, the manipulator descends onto the cap peak, the sucker is used for sucking the top surface of the cap peak, and the manipulator transfers the cap peak to a workbench of a sewing machine. Most of the caps are consistent in thickness, but for some caps with special structures, the thicknesses of the caps are inconsistent, for example, the front ends of the caps are thicker and the rear ends of the caps are thinner, the whole caps are designed to be thinner from front to back, therefore, the upper surfaces of the caps are inclined planes, the inclination angle of a single or a few caps is not obvious, but when the caps are stored, a plurality of caps are stacked up and down (for example, about 100-150 caps), the surface of the uppermost cap is larger in inclination angle due to the superposition and accumulation of a plurality of caps, although the bottom surface of the suction cup has deformability, because the inclination angle is larger, the suction cup is pressed downwards, the contact reliability of the bottom surface of the suction cup and the larger inclined surface is affected, and the contact effect with the conventional plane cap is difficult to form, therefore, the phenomenon that the material cannot be sucked easily occurs by adopting the conventional suction cup material taking method. Still, no matter be plane brim of a hat or inclined plane brim of a hat, adopt the sucking disc to get the material, when practical application, still have some problems, for example: 1. the phenomenon that the brim falls off from the bottom of the sucker easily occurs under the influence of the stability of an air source; 2. utilize the sucking disc to catch and move the material, the phenomenon that the brim of a hat rotatory skew appears easily leads to the brim of a hat locating position inaccurate, influences sewing processingquality.
