The present invention relates to systems and methods for automated fabrication of garments and similar articles.
Despite technological advances and introduction of automation in many types of manufacturing, garment manufacturing remains very labor intensive. Sewing machines were invented in the early nineteenth century and were made possible based on the development of the lock stitch sewing technique. Today, some hundred fifty years later, this same technology remains the foundation of garments manufacturing. The modern process of producing large quantities of ready-to-wear apparel relies heavily on manual labor and relative to other industrial manufacturing it remains inefficient. 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 apparel 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 twenty first century innovations and advances in material handling, in most small and large apparel manufacturing factories, most of the material handling and apparel 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 apparel 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 manual manipulation, including loading, unloading piecemeal work in and off the tool.
Few garment manufacturing innovations attempt to address the inefficiencies of the apparel manufacturing process at the system level. Continuous methods and systems have been proposed but all include limitations that have prohibited mass implementation of the system. US reissue Pat. Re. 30,520 describes a “Method of Manufacturing Jackets and Like Garments” in an assembly line fashion, using at least two webs of fabric, one used to form the jacket and one used to form the sleeves. Although this patent proposes a continuous manufacturing process, garment formation restrictions force sleeve holes that extend to the neck hole, resulting in a garment with an undesirable shape and design, which may be at least one reason this manufacturing system does not appear to have been implemented in any production facility.
U.S. Pat. No. 3,681,785 entitled “Garment Production with Automatic Sleeve Placement” describes a continuous garment manufacturing system where left and right pre-formed sleeves are placed and secured to the back panel of a jacket or shirt that is patterned on a continuously moving web. The system proposed in this patent requires the accurate registration and synchronization of the movement of garment body web to match the movement and placement of each individual sleeve accurately with respect to a moving web under very tight manufacturing tolerances. This synchronization is further complicated by the proposed handling of each sleeve, lacking stiffness and yet required to be flipped 180 degrees from their resting position onto its destined location on garment body on the web. The material handling requirements of the '785 patent are impractical and due to the pliable nature of any garment fabric and the required accurate placement of the sleeves on the garment body on the web.
Similarly, U.S. Pat. No. 3,696,445 entitled “Garment Making Method,” and U.S. Pat. No. 4,493,116 entitled “Method for Manufacturing Sleeved Garments” propose manufacturing methods for forming garments in an automated process. As in the previous disclosures, both '445 and '116 propose forming sleeves in a separate operation and attaching the sleeves in a synchronized fashion to the garment body, requiring timely and complicated cutting, placing and attaching operations that render the implementation of the proposed methods impractical.
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. To satisfy the growing need in fulfilling small batch or mass customized orders, garment manufacturing systems that are highly automated, programmable, and reconfigurable to accommodate an increasing mix of design, material selection, sizing and joining techniques are desired.
For a fuller understanding of the nature and advantages of this invention, as well as the preferred mode of use, reference should be made to the following detailed description read in conjunction with the accompanying drawings. The drawings are not presented to scale unless specified otherwise on an individual basis.
The following description includes the best embodiments presently contemplated for carrying out the invention. This description is made for the purpose of illustrating the general principles of this invention and is not meant to limit the inventive concepts claimed herein in any way.
Some embodiments based on the present disclosure provide for systems and methods for transferring and manipulating fabrics and joining garment components during garment manufacturing in a way that is more suitable to automation. Some embodiments provide for garment manufacturing systems and methods that are reconfigurable to enable both mass production of customized garments and small batch processing with reduced human intervention.
As previously mentioned, traditional methods of making a garment require converting various measurements of body parts into two dimensional layouts (panels) corresponding to the various garment pieces or sections, cutting garment pieces out of webs of fabric, and using a variety of manual or semi-manual operations requiring a great deal of hand-eye coordination and manipulation to assemble together the various pieces of fabric to make a garment. This heavy reliance on manual processes is inefficient when compared to most modern manufacturing systems and processes. Additionally, reliance on manual labor, especially labor with specialized skills is expensive, and inherently more prone to errors depending on the required skill, resulting in products lower yields due to higher defects, resulting in more rejections and increase costs. Simply put, the current garment manufacturing process remains heavily reliant on antiquated systems and processes carried over from the industrial revolution from the beginning of the 19th century. Therefore, it would be highly desirable to create systems and processes for garment manufacturing that lend themselves to significantly reduced reliance on manual product manipulation and handling, promote continuous garment manufacturing methods over piecemeal processing, and offer flexible systems that can mass produce items while allowing for customized production.
Embodiments based on the present disclosure cover processes that combine an adhesive to affect the permanent bonding of a variety of types of fabric, with a series of integrated mechanical processes to eliminate or greatly reduce material handling issues and the human intervention traditionally required in the garment manufacturing process. This will increase the speed and efficiency of the processes, improve the overall quality of the finished garments and provides for flexible systems that can mass produce items while allowing for customized production, whereby production items can be adjusted to individual size and style. Exemplary embodiments of the present invention provide for seam formation, joinder and cutting tools that are adaptable and programmable such as to allow automated and customizable garment manufacturing systems and processes.
Exemplary embodiments of the present disclosure will be described with reference to the manufacture of T-shirts. However, it would be understood that these described exemplary embodiments may be easily adapted to produce other types of garments including long sleeve shirts, dress shirts, jackets, pants, gloves, or non-garment products such as bedsheets, pillowcase, table cloth, rugs or handbags, etc. Therefore, the exemplary embodiments of this disclosure should not be interpreted as limiting the scope of the present disclosure.
Turning now to the drawings,
In some embodiments, a web may comprise a continuous flat layer of fabric laid out in two dimensions. In some embodiments, the web may include shapes other than a flat sheet, including any three-dimensional shape such as a tube or other shapes. In some embodiments, the web may not include a continuous sheet of fabric. In some embodiments, the web may act as a scaffolding (not shown in the drawing) or carrier for fabric components that are secured to the web by some means and are acted on as the web travels through a path. In some embodiments one or more webs may include perforations along one or more borders. In some embodiments, one or more webs may be coupled to a scaffolding (not shown in the drawing) that includes perforations along one or more borders. In some embodiments, one or more fabric webs (e.g. webs 102 and 104) may include perforated borders made of the same material as the web and integral to the web or made of the same or different material than the web and is attached to the one or more fabric web. In some embodiments, the border perforations of the web or the scaffolding may be used to pull the web along a given path by a system of one or more gears, providing control of the movement of the web and synchronize the movement of the web to other moving components of the exemplary manufacturing system. In exemplary embodiments, the sheet of fabric 102 is dispensed from the fabric roll 118 that is operable to rotate about its axis and dispense the web 102 along the X-axis Similarly, web 104 is dispensed from the fabric roll 120 that is capable of rotating about its axis and dispensing the web 104 along the X-axis. In some embodiments, roll 118 and/or roll 120 are coupled to one or more actuators, gears, motors (continuous or step) that rotate at a selected speed pulling or pushing the web along the X-axis. In some embodiments, rolls 118 and 120 are free to move but are not mounted on motorized shafts. In these exemplary embodiments, the webs 102 and 104 may be pulled by one or more actuators or motors located at suitable locations other than roll 118 or 120 rods. In some embodiments, actuators or motors are located at rollers 113 and 115, rollers 122 and 123, rotary die roller 112, and/or other suitable locations, providing pull or push forces acting on the webs 102 and 104. In some embodiments, one or more rollers include actuating means that are operable to being actuated independently and activated in a way to distribute the application of the pull or push forces along the webs 102 and 104 to reduce the chances of damaging the fabric by overly stressing, straining or even tearing fabric web at one or more locations. In alternative embodiments, the webs 102 and 104 may have borders made of the same or different material, that may be perforated or include a greater friction coefficient, and where the border material is reinforced or inherently has greater tensile strength and provides for an area that may support and tolerate greater stress or strain forces than the fabric web materials can tolerate without affecting the quality of the fabric webs.
In some embodiments, the front half contour 105 and/or back half contour 103 of the T-shirt 114 include markings to further define the T-shirt 114's borders on the corresponding webs 102 and 104. In exemplary embodiments, the front half and back half contours 105 and 103 of the T-shirt 114 may be temporarily marked by visible, invisible, or washable ink. In other embodiments, no demarcation may be used to identify the contours of front half 103 or back half 105 of T-shirt 114. In some embodiments, the outer face of the back half 103 and front half 105 of the T-shirt 114 may be facing out as shown in
In exemplary embodiments, adhesive dispensers 106 and 108 dispense adhesive along the contours of the back half 103 and/or front half 105 of the T-shirt 114, except may be in the neckline region, sleeve opening and bottom opening of the T-shirt 114. The regions with no adhesive may remain open and form the neck, arms and body holes after the final cutting and finishing steps further described below.
In exemplary embodiments, after the deposition of the adhesive, web 102 and the web 104 continue to travel along the X axis toward a joinder point where webs 102 and web 104 are pressed together using one or more rollers (e.g. rollers 110, 122 and 123). In some embodiments, beyond the joinder point, the web 102 and web 104 are pressed together using a predetermined force, heat, radiation or moisture to activate any adhesive applied to the back half 103 and front half 105 of T-shirt 114, and attach the back half 103 and front half 105 of T-shirt 114 to form an integral complete garment. In some embodiments, in addition to pressure, heat, radiation or moisture are applied to web 102 and web 104. In some embodiments, the rollers 110, 122 and 123 supply pressure, heat, radiation, or moisture uniformly to the web 102 and web 104. In some embodiments, pressure, heat, radiation, or moisture may be applied only to certain regions of the back half 103 and front half 105 contours that have applied adhesive. In some embodiments, the pressure, heat, radiation, or moisture may not be applied through the rollers. In some embodiments, some or all the pressure, heat, radiation, or moisture may originate from sources other than the rollers 110, 122 and 123. In some embodiments, heat and radiation may be applied by conduction, radiation, or convection. In some embodiments, energy sources such as lasers, heat guns, or hot plates may supply the energy.
It should be apparent that synchronization of the movements of web 102 and web 104 are important. In some embodiments, mechanical means such as belts, chains gears and sprockets are used to actuate the movement of web 102 and 104 in sync. In some embodiments, electronic controls along with variable speed motors and/or step motor may be used to control the movement and speed of webs 102 and 104 in order to maintain web 102 and web 104's movement in synch and provide for the accurate registration and alignment of the back half 103 to the front half 105 of T-shirt 114. In some embodiments one or more webs may include perforations along one or more borders to be operable similar to a chain and sprocket conveyance mechanism operating on one or more webs 102 and 104, or any other webs (not shown in
With reference to
In some embodiments, I-shirts 114 remain fully or partially attached to the web 102-104 to continue to travel as part of the web 102-104 for easier material handling during additional processing. In some embodiments, additional processing may include customization operation of garment 114 including embroidery, DTG (direct-to-garment) printing, screen printing, etc. In some embodiments, after all processing is completed, T-shirts 114 are cutout of the web 102-104 and processed for final packaging.
In some embodiments, folding tools or mechanisms 232 may be used to fold cut or uncut edges of one or more web 202 and web 204, before or after the deposition of adhesive on the article edges prior to folding and forming a seam. Folding tools and the formation of various types of seams will be farther discussed in
In some embodiments, the adhesion of back half 103 to the front half 105, or the adhesion of any other garment parts to another may be achieved using a laser. In some embodiments, a laser beam may be used to provide heat energy to activate one or more layers of adhesive acting to bind garment components. In some embodiments, garment parts made of synthetic fibers may be fused together directly using heat in any form such as a laser to melt the synthetic fibers of the garment parts.
In some embodiments, adhesives may be dispensed in a single layer. In some embodiments, adhesives may be dispensed in one or more layers. In some embodiments, a single formulation or type of adhesive may be used for all layers. In alternative embodiments, different types of adhesives with different properties may be used for different layers. In the illustrative example of
In some embodiments, the adhesive is applied using one or more patterns, each pattern designed to achieve different properties. In some embodiments, the adhesive may be applied in a non-linear pattern such as serpentine, zig zag or curvilinear 416 manner within a defined band or border, along the perimeter of the back half 103 or front half 105 of garment 114. In some embodiments, certain adhesive patterns may provide a greater degree of movement or stretchability at the joint in a particular direction while still retaining sufficient seam strength. In some embodiments, the adhesive may be applied in discrete non-contagious dots 418, non-contagious stripes or ellipsoids 420, and positioned at one or more angles with respect to the borders of the garment. In some embodiments, the application of a pattern of non-continuous adhesive may impart the necessary bonding strength while reducing the amount of adhesive consumed as compared to a pattern requiring the continuous application of adhesive to the same area.
In some embodiments, cut/fold head 510 includes a folding tool 512 (also referred to as the folding head or folding mechanism) and a cutting tool 514. As shown in
In some embodiments, the cut/fold head 510 includes a cutting tool 514. In some embodiments, each cut/fold head 510 may include a single tool such as a cutting tool 514 or a folding tool 512. In some embodiments, the cut/fold head 510 may include a cutting tool 514 and a folding tool 512 on the same tool head. In some embodiments, each cut/fold head 510 may include one or more cutting tools 514 and/or folding tools 512 based on the manufacturing processes and the garment design requirements. In some embodiments, the cutting tool 514 may be a mechanical cutter such as a knife, a blade, a scissor or needles. In some embodiments, the cutting operation is performed by needles that may perforate the borders of the garment 114 while leaving the garment 114 attached to the web until further processing completes the separation of the garment 114 from the joined webs 102 and 104. In some embodiments, the cutting tool 514 may use a laser cutter or other non-mechanical cutting devices. In some embodiments, the cut/fold head 510 may include one or more cutting tools 514, each including different physical or operational characteristics. In some embodiments, the cutting tool 514 may be extended or retracted along an axis (Z-axis) perpendicular to the plane of the web 102, 104 or other webs. In some embodiments, the cutting tool may operate in a fixed direction with respect to the direction of travel of a web and thus operable to cut the fabric in a fixed direction. In some embodiments the cutting tool may travel along any path as defined by combinations of X,Y coordinates and rotate in clockwise or counterclockwise directions up to 360 degrees with respect to the web. The ability to rotate may be required of a mechanical cutter to produce non-linear seams. The same limitation may not apply to non-mechanical cutters such as a laser cutter. In some embodiments, a cutting tool 514 is in a static position in front of the folding tool 512 with respect to the direction of motion. In some embodiments, the cutting tool 514 and folding tool's 512 positions with respect to each other are adjustable prior to the start of the manufacturing operations and/or dynamically during the manufacturing operations. In some embodiments, the cutting tool 514 cuts the web fabric 102, 104 and other fabric webs per the garment design specifications. In some embodiments, as the cutting tool 514 cuts the web according to the design specifications, the folding tool 512 may engage in folding the cut sections of the fabric into a desired fold or seam shape. In some embodiments, seams are formed after applying adhesive, folding and/or cutting web material per a given design specification that dictates the sequence and coordinates for the application of each adhesive, fold and cut operation. Various seam shapes may be achieved using the cut/fold system and method described in this disclosure. Exemplary seam formations are further described below in
It would be apparent to one skilled in the art that the above bonded seam types are illustrative examples only. A variety of bonded seams may be formed using the cutting, folding, inserting processes described in this disclosure. It would be apparent to one skilled in the art that one or more types of bonded seams may be required by the design or manufacturing specifications of a particular garment, in addition to limitations and requirements imposed by the nature of the fabrics and adhesives, aesthetic, endurance, sealing or permeability requirements of individual seams.
In operation 704, the three-dimensional garment design data are converted into the dimensions of individual components of the garment to be manufactured. The garment dimensions may include length and width of the body, the sleeves, the neckline, etc. of the garment. Based on the type of the fabric selected, the garment component dimensions may be adjusted to account for fabric properties such as stretch.
In operation 706, the 3D geometries of the garment components are converted to a 2-D representations. In operation 708, the two-dimensional representations of the garment are mapped or laid out onto one or more fabric webs. In some embodiments, the pattern of mapping garment components on one or more fabric web is laid out in panels in such a way to simplify fabrication, minimize material waste, or both.
In operation 710, based on the dimensions of the laid-out garment, the type of fabric or the aesthetic design of the garment, the bonding edges, shapes and the free edges of the garment are identified. The layout of the garment on the fabric web may include the steps of selecting which garment component panels are to be laid-out on which web, (e.g. right, left, upper or lower web). Additionally, considerations for the layout of the garment panels may include laying out the garment pieces inside-out or outside-in, headfirst or bottom first, etc.
In operation 712, the garment layout dimensions may be adjusted to accommodate the appropriate bonding border requirements including adhesive line width, adhesive dispensing pattern, cutting path and dimensional quality assurance specification for the finish garment.
In a parallel process flow path, in operation 714, based on the received 3D garment design data, the automated garment manufacturing system 100 may select the corresponding fabric web and load each fabric web in preparation for the start of manufacturing. In some embodiments, the selection and loading and preparation of the fabric web may be performed manually, semi-manually or automatically. In some embodiments, some or most of the material handling operations required at this step may be done automatically, for example using robots and cobots.
In operation 716, based on the garment design data, a joinder recipe is selected which determines the adhesive type to be used, the adhesive patterns (straight, zigzag, serpentine) and the adhesive curing parameters.
Finally, in operation 718 the cutting recipe is determined based on garment design data. For example, a particular cutting recipe may be used to minimize material waste or achieve a certain aesthetic design requirement.
In operation 720, adhesive is applied to on one or more moving fabric webs per the manufacturing recipe created in operation 716. In operation 722, one or more webs are joined at least along areas where adhesive has been applied. Heat, pressure, moisture, radiation and/or catalysts may be applied for a given period of time (as per the manufacturing recipe) to the joined areas to activate and cure the bond between the joined web regions. Each of the parameters used to create a joint may be individually tuned and adjusted to achieve the optimum bonded joint based on the garment type, the joint type, dimensions, type of adhesive, whether the joint must be waterproof or not, and the aesthetics of the joint.
In operation 724, the joined regions that are formed by bonding one or more web areas together are cut on the outside perimeter of the joint, along the edge of the joint or at some distance within the joint. In some embodiments, the cutting along the joints may be complete along the entire garment perimeter, in which case the garment is hereafter fully detached from the webs. In some embodiments, the cutting operation may be limited to specific boundaries of the garment that may include bonded edges and free edges where no adhesive has been applied. In some embodiments the cutting operation may achieve both a functional and an aesthetic function. In some embodiments, the cutting operation may be limited to certain areas of the garment perimeter and the garment remains attached to the fabric webs until further processing. In some embodiments, the cutting is performed using needles to perforate the web but not to completely detach the garment from the web. In some embodiments, the final detachment of the garment from the web may be performed at a later stage in the garment manufacturing.
In some embodiments, in operation 726, based on the garment design data and the corresponding manufacturing requirements, the system determines whether each layer of a garment part with unbonded free edges (e.g. sleeve holes, neck hole) must align to each other or not. For example, for increased comfort wear, some T-shirt designs may require the layer of fabric layer forming the back of the neck section to be longer (taller as measured from the T-shirt hemline) than the front layer of fabric comprising the neck hole.
In some embodiments, in operation 728, if the garment design data requires the open edges of the garment in some area to be aligned between the two webs, then a single cutting operation may be performed on both layers of the garment. For example, both the lower and upper layers of fabric forming the sleeve hole may be cut in a single cut operation.
In some embodiments, in operation 730, if the garment design data requires the opening fabric edges not to align (e.g the fabric layer of the back of neck hole must be longer than the fabric layer at the front of the neck hole), for each cutting operation, one fabric layer may be cut while the other fabric layers may be protected by an insert between the cutter and the other layers of fabric. For example, in the case of some T-shirt necklines, the edge of the back layer of fabric for the neck hole must be higher than the edge of the front layer of fabric for the neck hole. In such cases, the cutting operation may be performed in separate steps, using one or more cutters to cut a given fabric layer while protecting other fabric layers using a protective insert.
In operation 732, a quality inspection of the finished garment may be performed. In some embodiments, the quality inspection may be performed by human operators through a visual inspection. In some embodiments, a quality inspection may be performed using cameras using artificial intelligence. In some embodiments, the quality inspection may be performed while the finished garment is still attached to the web to simplify any material handling issues.
