DETAILED DESCRIPTION OF THE INVENTION
[0032] It will be appreciated that Garment System in accordance with the preset invention facilitates efficient and comprehensive end-to-end management of the garment manufacturing process.
[0033] As used herein, the term garment is used in its broadest sense and is intended to include not only apparel but also to include any flexible material. In the art, garment manufacturing often utilizes weaving looms, knitting machines that produce plain and printed fabrics, printers that print patterns, colors, and other marks on fabric that may be used in manufacturing and information tracking. Garment manufacturing also often utilizes cutters that cut based on previously entered information.
[0034] In
[0035] The printer 20 may print color, images, and/or patterns that are incorporated into garment 10 based on its design and other indicia that are used during the manufacturing process. For example, the printer 20 may print QR or bar codes or color coding on the fabric in areas that are not visibly incorporated into a garment but are used by an online development environment of the present invention Garment System to gather various information about the garment and aid in the manufacturing process. For example, the printer 20 may add orange tags on fabrics to indicate that those parts are to be assembled together when scanned by scanner 320 into the online development environment. The Garment System may then direct such parts to be grouped together and processed in an organized manner. Alternatively, the tags may be used by machine operators or robots to deliver particular parts to a specific destination. Printed notation indicia may be printed in the non-visible areas of the garment part to stay with the garment part throughout the manufacturing process.
[0036] A preferred embodiment of this invention would allow for printing with printed fabric or material directly connected to a computer controlled cutter 77 to enable a continuous workflow with cutting directly following printing. In some instances, the cutter may require sufficient length of fabric before complex or elongated patterns can be cut. For example, cutting three hundred petals of three-inch diameter flowers would require considerably longer time to process than cutting a dress with large dimension panels. As shown in
[0037]
[0038] In contrast,
[0039] As seen in the Figures, particularly
[0040] Upon movement of the material through the material web transporter 200, the material accumulator 310 acts as a buffer to modulate any potential difference in speed between the printer and cutter. It may be appreciated that the present invention measures the length of the fabric from the printer and directs the cutter to begin cutting complex or elongated patterns only when sufficient length of fabric is accumulated in the accumulator. The present invention may alternatively direct the printer and/or cutter to proceed at a faster or slower speed, so that the cutter and printer combination can manufacture garment in a continuous manner or in a planned throughput based on a factory and/or group sewing capacity thus keeping in-process inventory to a minimum. In an alternate embodiment, the tension-maintaining function of the material transport system is built into the accumulator eliminating the need for two separate devices.
[0041] More specifically, the material web transporter 200 comprising a set of rollers 400, 410, 420, 430, 440 designed to create traction for properly tensioned material path for the material transport from printer to cutter. It is envisioned that any number of rollers can be provided in the material web transporter 200 and the embodiment seen in
[0042] The accumulator 310 acts as a buffer between the printer 20 and the cutter 77 by providing a means to hold and accumulate material 10 after the printing process and before cutting is initiated, given that printing may be continuous while cutting is done periodically (e.g., once enough material has been printed). The accumulator 310 can also compensate for the rate of speed at which material 10 comes off the printer 20 and the rate at which it enters the cutter 77. More specifically, the accumulator 310 is designed to prevent the cutter 77 from advancing without sufficient material 10 available from the printer 20, eliminating the possibility that the cutter 77 pulls material 10 directly from the printer 20 at a rate higher than that which the printer 20 is capable of printing, thereby causing an undesired spike in tension. The accumulator 310 communications physically and electronically with the material web transporter 200 to move the moveable roller(s) and pass the material 10 there-through until a sufficient amount of material is ready for passage to the cutter 77. The accumulator 310 can also sense the length of material accumulated to signal the printer 20 to slow down or stop in the case where the cutting function vs. printing is too greatly mismatched due to complex cutting geometries or in case of a tool change. This ensures that the material 10 is available and both properly aligned and provided with the proper tension to enter the cutter 77 at the proper rate so that the material does not bunch up at the cutter 77 and does not pull the successive material through the printer 20 and ruin the printing process. The accumulator 310 also allows on-demand cutting separate from the connected printer for material either previously printed and removed from the printer, or printed on another printer. This eliminates unnecessary printing if printed material already exists, and allows for on-demand cutting and on-demand sewing, irrespective of where or if the material was printed.
[0043] As seen in
[0044] In this way, the intermediate manual input step of moving a roll of printed material onto a cutting machine, and re-aligning the same, is eliminated, as the present invention Garment System allows the material to continue along the printing process and directly into the cutter, maintaining tension and proper alignment throughout the entire roll of material.
[0045] In one embodiment, a printer and a cutter may be paired to manufacture a garment from multiple fabrics. As an example, a garment may call for a body of one fabric and another type of fabric for the sleeves. Alternatively, panels within a dress may be made of different types of fabrics. A preferred embodiment of this invention would utilize multiple printers and cutters to manufacture a garment, with each printer and cutter combination responsible for each type of fabric. Alternatively, a single cutter may service multiple cutters. The present invention Garment System can connect all components of the manufacturing process and steer orders or components between micro factories based on workload, geographical preference, material locale, equipment loading, or the like. The latter arrangement would be especially beneficial in a high volume manufacturing process, as printers may require calibration each time a different material is switched out and they print on different types of fabrics. Accordingly, the latter arrangement would save the time that may be spent to switch out each fabric and calibrate the printer. The Garment System may then gather data in relation to the manufacturing process and coordinate different aspects. For example, the Garment System may direct cut garments and garment parts from different types of fabrics to be sent to a processing station with the use of QR or bar codes noted above. Additionally, it may detect a back log of uncut fabric and coordinate a cutter to work faster or with less delay.
[0046] In yet another embodiment, multiple printers, each responsible for a different type of fabric, may be connected to a single cutter. The Garment System may coordinate which fabric from which printer is processed through the cutter in a preferred order, in order to maximize the speed of the manufacturing process. Information along the process will be tracked and made available for local or centralized reporting and additional data processing. As shown in
[0047] In yet a further embodiment, the Garment System is configured connect multiple individual print-to-cut subsystems, each responsible for a specific fabric printing and cutting. Multiple individual print-to-cut subsystems can be connected, both physically and electronically, and controlled by a control system on a computer or mobile device with processor, to allow for instructions to be transmitted between sub-systems for moving fabric from a printer of a first sub-system to a cutter of a second sub-system when needed, or to instruct new printing and cutting of a particular amount of material in a first sub-system based on an existing printed and cut amount of corresponding and complementary material from a second sub-system to complete a requested order. The control system can include automated instructions for operating each of the continuous print-to-cut sub-systems, and can be run through manual input with on-demand instructions when a change to the process is needed, as set forth in the example above.
[0048] In addition to garments and garment parts that are printed and cut, the Garment System may track and coordinate processing of garments that are not printed. For example, there may be linings or other elements that are provided from other sources in manufacturing. Such garments may carry sewn or stamped tags that the online development environment of the Garment System may track and, for example, be put in the cutter without first going through the printer. The Garment System can digitally monitor the use of such garments and garment parts in manufacturing, the same way it tracks garments out of the printer and cutter arrangement discussed above.
[0049] Additionally, the Garment System may direct printing of garments without any need for cutting. With the advent of 3D printing, it is now possible to print garments, filament by filament, in the form of a desired apparel or part of apparel. The Garment System may even allow direct connection between the design program and the printer, so that a designers can request printing of their CAD designs at the manufacturing site without any intermediary.
[0050] As the Garment System monitors the overall cutting and printing processes, it may also monitor components of printer and/or cutter for workflow and utilization. For example, the Garment System may receive various data from a cutter, such as temperatures, pressures, forces, and angles. If the Garment System detects too much vibration or unusual increase in temperature, it may direct the cutter to take necessary actions, such as reduce the rate of cutting, or provide alerts. It may be appreciated that such detection and alert may preempt any actual interruption in manufacturing. For example, a call to replace or perform preventative maintenance on a motor would minimize downtime that may result from an actually broken motor. Additional communication may include the Garment System communicating with an e-commerce or other electronic system to dispatch spare parts and/or consumables required by machines that are part of the Garment System.
[0051] The Garment System may be operated from a local computer and/or server at a manufacturing site, or preferably operated with the use of cloud computing and artificial intelligence (AI) technology. In the latter arrangement, the Garment System may not only collect data along the manufacturing process and provide directions, but also apply machine learning to optimize the manufacturing process and/or make recommendations to consumers, designers, and manufacturers along the supply chain. For example, the Digital Garment System may determine an efficient manner of manufacturing a dress from a specific type of fabric. Then, it can make recommendations for future dress manufacturing, such as what types of print-to-cut arrangement work efficiently, what supplies are available, how to reroute production if necessary, and how much cost could be attached to types of garments and manufacturing processes. The Garment System may also be used to learn and provide information that are not directly utilized in manufacturing. For example, the Digital Garment System may determine from the genealogy of garments that have been previously manufactured what kind of sustainability information is attached to the type of fabric, what causes allergies and other issues, and where and when the garment was created. The Garment System may even suggest new designs and manufacturing options based on certain consumer trends for the manufacturer or recommend certain style for a particular consumer based on previous orders.
[0052] It should be noted that the input device for the Garment System of the present invention is not particularly limited, and may utilize voice and/or image recognition. As an example, the Garment System may steer a consumer to a particular design or brand based on images the consumer provides, prior order history, or other related metadata pertaining to the specific customer. In yet another embodiment, the Garment System may operate in a hybrid configuration of local and cloud, such as Edge Computing. In such configuration, the Garment System may be stored and operated from a local computer, which synchronizes with central data server or cloud at a predetermined frequency.
[0053] It may be appreciated that the Garment System could be utilized to monitor and optimize productivities of multiple manufacturing sites. As an example, the Garment System may detect that printers and cutters at one manufacturing site are not manufacturing garments at an optimized rate. This may include multiple cutters or manufacturing equipment from different suppliers and in different regions that are all linked into a production system as part of a multi-sided marketplace. While the Garment System makes or recommends appropriate changes, it can also arrange for switching to a different manufacturing site within the next day or even instantaneously. Additionally, the Garment System may acknowledge that a particular cutter is down for maintenance and send the work to a different machine or a different manufacturing site temporarily. Benefits of such flexible optimization would grow as more and more manufacturing sites are managed by the Garment System and as order volume increases. For example, the Garment System responsible for dozens of manufacturing sites and millions of orders coming in everyday may direct manufacturing to a site with greater capacity or supplies or to a site that is closest to the end consumer. The Garment System may offer such arrangement as a purchasable option to the end consumer, who is willing to pay additional costs to have her work finished ahead of schedule at a manufacturing site that is available.
[0054] It bears repeating that the Garment System may track the garment genealogy with the use of printed information, such as QR or bar codes or color coding. Such markers can be printed on the parts of the fabric that does not become a garment, such as the edge of or margin the garment, or printed with invisible means such as UV reflective paint. The printer may print the date and location of printing, the name of the end customer, manufacturing instructions, and any other information that may be used by the Garment System to track the garment's genealogy. The Garment System may also be used to provide ongoing updates to end customers of the garment about the state and genealogy of their order and garment throughout the process.
[0055] It may be appreciated that the aforementioned printers and cutters can be arranged so that the cut garments and garment parts can be processed by machine operators or robots in an efficient manner, such as a circular line configuration as shown in
[0056] While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications will be appreciated by those skilled in the art to adapt a particular teaching of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
