Used 2nd Hand Sewing Machine - vssewingmachine
The industrial manufacturing of
sewn products has always been one of the critical processes of the
textile chain concerning quality assurance. Assuring the appropriate
set-up and operation of all the machines, and thus the final seam
quality, is a very complex task. Traditionally, this task is
accomplished by empirical methods, with machine setting and quality
control relying on the skills of operators and technicians. In this
work, an approach to a more knowledge-based and integrated process
planning and control is presented. A system was developed to measure and
analyze the most important mechanical effects occurring during
high-speed sewing. A general overview over this development is given in
this paper. Read More
Among the processes for making
final products using fibers, the final process can be called a sewing
process. The sewing process generally corresponds to the process that
requires the most manpower in the production of textile products. The
cost of sewing has gradually increased due to the recent rise in labor
costs. The automation of the sewing process and the smart factory are
expected to be carried out along with the fourth industrial revolution.
In order to make the sewing factories smart, it is essential to apply
smart sensing technology to the sewing machines. Also, sewing Process In
order to grasp real-time situation, a system to monitor the status of
each machine is needed. This study can be regarded as a part of
technology development for automation and unmanned sewing process for
final CPS(cyber-physical system) implementation. Three techniques have
been developed in the sewing machine modification technology to assist
the smarting and sewing process of the sewing machine. Three kinds of
developed technology are a bobbin remaining amount detecting technique,
stitch length control, and monitoring techniques. As a result of
step-by-step technology development to realize CPS finally, it is a
partial technology development of automation through some modification
of sewing machine. The developed technology is expected to be used as a
technology for future smart sewing automation plant construction.
o address some of the problems stated previously, in particular the quick response to small production orders, several new production organization methods have been devised. These are based on higher flexibility and interchangeability of the operators, smaller production units and batch sizes, and higher mobility of the production equipment. But the simple reorganization of production cannot address all issues: the variables related to the production process itself are still not controlled. Set-up of the machines is empirical and thus inaccurate and time-consuming. Initial set-up is maintained during operation regardless changing sewing conditions. Quality is assessed by visual inspection, often causing defective parts to pass unnoticed or to be detected very late. Click Here
The approach proposed in this work relies on the evaluation and analysis of the relevant sewing parameters and their relation to quality problems and machine set-up variables. This integrated approach has enabled the development of methods to automatically detect sewing defects and seam quality, and to propose control methods for certain machine adjustments
