TECHNICAL FIELD

The embodiments herein generally relate to manufacturing of garments and more particularly to a system for automated manufacturing of garments.

BACKGROUND

Generally, sewing machines are used for sewing multiple fabric sections to form garments. Despite technological advances and introduction of automation in many types of manufacturing sectors, garment manufacturing remains very labor intensive and therefore cost intensive. Ready-to-wear garment is typically manufactured in factories which produce large numbers of garments at a time. The process of producing large quantities of ready-to-wear garments remains inefficient relative to other industrial manufacturing sectors. Garment manufacturing includes multiple steps including sizing, folding, fitting, cutting, sewing, and material handling. The type of tasks needed dictates the level of skilled labor that is required to perform the work. The unique and varied properties of fabric such as weight, thickness, strength, stretchiness and draping as well as the complicated nature of tasks required in garment manufacturing complicates material handling and automated garment manufacturing. The garment manufacturing process starts with cutting one or more layers of fabric based on patterns and dimensions matching the desired garment. Then, the cut fabric patterns are transferred from workstation to workstation, where at each workstation, one, two or more pieces of fabrics are manually folded, overlapped along the seams and fed into a sewing or serger (overlocker) machine. Given the variety of fabrics, threads, seam types and stitch types found in a finished garment, a larger number of workstations with specialized tools and skilled operators is required for assembling a garment. This means the fabrics or unfinished garments spend a lot of time in transit between workstations. Unlike most many manufacturing industries benefiting from recent innovations and advances in material handling, in most small and large garment manufacturing factories, most of the material handling and garment manufacturing operations are conducted in a manual or semi-manual manner.

Currently, despite advances in technology, machines still struggle with performing certain tasks that are easily handled by a trained worker with average hand-eye coordination skills. This is one reason garment manufacturing industry is in a constant search of cheaper human labor rather than investing in advanced automated manufacturing systems. So, in many cases, the difference between small and large garment manufacturing operations is the number of workers it engages to increase production, a factory may add additional production lines in parallel. However, in general, increasing production in this manner does little to improve efficiency. Even in large factories, most work is performed in piecemeal fashion, with limited coordination between various stations/steps, and movement of material between each station requires a great deal of manual product handling. Therefore, the entire garment manufacturing process remains labor intensive and inefficient, where work is performed in a discontinuous batch processing fashion, causing garment manufacturers to move from country to country in a continuous search for lower labor costs for manual and semi-skilled labor. Most of the innovations in the garment manufacturing industry have been directed to improving individual tools. For example, new features may be added to a sewing machine to convert it from manual to a semi-automatic or automatic tool. However, all material handling needs would still require a manual manipulation, including loading and unloading piecemcal work in and off the tool.

Another constraint in today's garment manufacturing is the inability to efficiently produce in small batches or mass produce customized garments tailored to every consumer's body shape and measurements. Manufactures rely on economies of scale and require minimum order quantity which may be out of reach for small brands and designers. Given the heavily manual and piecemeal processes in the current manufacturing operations, small batches or mass customized production that requires constantly shifting product designs, material selections and sizing and sewing techniques result in production difficulties and resulting manufacturing errors and resulting lower yields.

In addition to mass production in a factory, garment can also be prepared by hand by custom tailoring, whether at home or commercially by a tailor or seamstress. Custom tailoring generally involves measuring a customer, having a customer choose style, fabric, and fit preferences, sewing the garment, and potentially adjusting the garment's fit during the course of one or more fittings. The resultant garment has a fit and style which is personalized to the customer's preferences, but it is typically costly due to the large amount of manual labor involved preparing the garment and the amount of time required on the part of the customer. Consequently, custom tailoring does not constitute a large segment of the garment manufacturing industry.

Therefore, there exists a need for a system for automated manufacturing of garments, which obviates the aforementioned drawbacks.
