Embodiments presented in this disclosure generally relate to apparatus, systems, and methods for manufacturing fabric articles, such as garments.
Despite technological advances and the introduction of automation in many types of manufacturing, the manufacturing of fabric articles, such as garments, 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 and fifty years later, this same technology remains the foundation of garment manufacturing. The modern process of producing large quantities of ready-to-wear apparels relies heavily on manual labor, and remains inefficient relative to other industrial manufacturing processes. Garment manufacturing includes multiple steps including sizing, folding, fitting, cutting, sewing, and material handling. The unique and varied properties of individual fabrics, such as weight, thickness, strength, stretch, and drape, as well as the complex nature of certain tasks, complicates material handling and automated garment manufacturing.
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. The garment manufacturing process may start with laying out a web of fabric for 24 hours to relax the fabric and remove wrinkles. Then, one or more layers of fabric may be cut based on patterns and dimensions matching the desired garment. Then, the cut fabric pieces 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 machine or serger machine (also referred to as an overlock 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 much time in transit between workstations, which adversely affects the time required to complete a garment. Thus, traditional apparel manufacturing operations may include multiple sequential processes. Further, a time constant may be required between each operation to allow the fabric to relax, which further increases the time required to process a garment.
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 the garment manufacturing industry is in a constant search of cheaper human labor rather than investing in advanced automated manufacturing systems. To increase production, a factory may add additional production lines in parallel, which 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.
Accordingly, there is a need for an automated system for manufacturing garments to improve factory throughput and reduce reliance on manual labor.
Embodiments presented in this disclosure generally relate to apparatus, systems, and methods for manufacturing fabric articles, such as garments. In one embodiment, a method of manufacturing a fabric article includes unwinding a single web of fabric, thereby creating an unwound fabric, printing a design onto the unwound fabric at a first station, transporting the unwound fabric to a second station, and cutting the unwound fabric at the second station to create first and second components of the fabric article and a web of remainder fabric. The first component is created by cutting the unwound fabric around the design, and each of the first and second components includes a first side facing a work surface and a second side opposite the first side. The method further includes removing the web of remainder fabric from the first and second components, transporting the first and second components to a third station, and applying an adhesive to the second side of the second component at the third station. The method further includes transporting the first and second components to a fourth station, using a robot at the fourth station to position the first component onto the second component such that the second side of the first component faces the second side of the second component, and bonding the first component to the second component using the adhesive.
In another embodiment, a method of manufacturing a fabric article includes unwinding a single web of fabric, thereby creating an unwound fabric, printing a design onto the unwound fabric at a first station, transporting the unwound fabric to a second station, and cutting the unwound fabric at the second station to create a component of the fabric article. The component is created by cutting the unwound fabric around the design, and each of the component and the unwound fabric includes a first side facing a work surface and a second side opposite the first side. The method further includes transporting the unwound fabric and the component to a third station, and applying adhesive to a portion of the unwound fabric at the third station. The method further includes transporting the unwound fabric and the component to a fourth station, using a robot at the fourth station to position the component onto the portion of the unwound fabric such that the second side of the component faces the second side of the portion of the unwound fabric, and bonding the component to the portion of the unwound fabric using the adhesive. The method further includes transporting the unwound fabric to a fifth station, cutting the unwound fabric at the fifth station to separate the portion of the unwound fabric from a remainder of the unwound fabric, and removing the remainder of the unwound fabric from the portion of the unwound fabric.
In another embodiment, a method of manufacturing a fabric article includes unwinding a single web of fabric, thereby creating an unwound fabric, cutting the unwound fabric at a first station to create a component of the fabric article, transporting the unwound fabric and the component to a second station, applying adhesive to a portion of the unwound fabric at the second station, transporting the unwound fabric and the component to a third station, and using a robot at the third station to position the component onto the portion of the unwound fabric. The method further includes bonding the component to the portion of the unwound fabric using the adhesive, transporting the unwound fabric to a fourth station, cutting the unwound fabric at the fourth station to separate the portion of the unwound fabric from a remainder of the unwound fabric, removing the remainder of the unwound fabric from the portion of the unwound fabric, transporting the portion of the unwound fabric to a fifth station, and printing a design onto the component at the fifth station.
So that the manner in which the above recited aspects are attained and can be understood in detail, a more particular description of embodiments described herein, briefly summarized above, may be had by reference to the appended drawings.
It is to be noted, however, that the appended drawings illustrate typical embodiments and are therefore not to be considered limiting; other equally effective embodiments are contemplated.
To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures. It is contemplated that elements and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
Embodiments presented in this disclosure generally relate to apparatus, systems, and methods for handling fabrics, such as textiles, such as sheet materials, such as leather, cloth, and the like, in the manufacture of articles. Some examples of such articles include, but are not limited to, garments (e.g. shirts, pants, socks, shoes, shorts, coats, jackets, skirts, dresses, underwear, hats, headbands, and the like), accessories (e.g. wallets, purses, and the like), and homewares (e.g. artwork, upholstery, towels, bed linens, blankets, mats, and the like).
Some fabrics (so-called “single-faced fabrics”) include a “right side” designated to be on show in the finished article, and a “wrong side” designated to be hidden in the finished article. When such fabrics include a printed design, typically the print is applied to the right side. Additionally, when such fabrics are joined, typically the join is made right side to right side, then the joined fabrics are reversed (for example by turning inside-out) such that excess fabric at the join is hidden, and the right sides become facing outwards from each other. Some other fabrics (so-called “double-faced fabrics”) are created with two right sides and no wrong sides. Such fabrics are constructed such that either of the two right sides can be designated to be on show in the finished article.
Each system and method of the present disclosure may be used with single-faced and double-faced fabrics. Each system and method of the present disclosure includes the performance of manufacturing operations on a web of fabric and on items cut from a web of fabric. At least some of the manufacturing operations are performed with the fabric on a work surface, such as a cutting table, printing table, or the like. When on a work surface, each web of fabric—and any item cut from each web of fabric—includes a first side facing the work surface (i.e. facing down) and a second side opposite the first side facing away from the work surface (i.e. facing up). In each system and method of the present disclosure, either of the first side or the second side may be a right side.
A single web of fabric 212 is unwound, such as from a roller 214. In some embodiments, the unwinding operation is controlled by the controller 150. The unwound web of fabric 212 and/or a component cut from the web of fabric 212 is transported to a sequence of stations. In some embodiments, a conveyor transports individual fabric components between stations. In some embodiments, a robot transports individual fabric components between stations. At each station one or more operations are performed in the manufacture of the fabric article 220. The operations are performed on a work surface, such as a cutting table, printing table, and the like. In the Figures, the work surface 210 represents any work surface. In some embodiments, the work surface 210 is a conveyor.
In some embodiments, the work surface 210 is configured to selectively hold and release the web of fabric 212 and/or a component cut from the web of fabric 212. In an example, the work surface 210 includes one or more electrostatic plates. In another example, the work surface 210 includes a vacuum assembly, such as a perforated plate coupled to a vacuum pump. In some embodiments, operation of the fabric holding mechanism of the work surface 210 is controlled by the controller 150.
The unwound web of fabric 212 is transported to station 201, which includes a printer 230. The printer 230 prints a design 223 onto the web of fabric 212. In some embodiments, the printer 230 includes a printhead 232 that is movable with respect to the web of fabric 212 while printing the design 223. In some embodiments, such as in the manufacture of fabric articles 220 that do not include a printed design 223, the printing operation may be omitted.
In some embodiments, the printer 230 may comprise at least one of: a Direct To Garment (DTG) printer, a sublimation printer, or a screen printing printer. In some embodiments, the fabric 212 may be a single color fabric, such as white color fabric, and the printer 230 may print on part of or on the entire fabric 212 to dye, colorize, or create a customized color and design pattern. In some embodiments, the printing by the printer 230 may be performed as an on-demand process, based on the requirements of the particular job. In an example, the color(s) and/or pattern(s) applied by the printer 230 are tailored for the manufacture of each individual fabric article 220.
In some embodiments, the printer 230 is controlled by the controller 150. In an example, a sensor associated with the printer 230 detects a feature of the web of fabric 212, such as a fiducial on or in the web of fabric 212. The controller 150 uses information of the detected feature to direct the printer 230 to print the design 223 at a specific location of the web of fabric 212.
Then the web of fabric 212 is transported to station 202, which includes a cutter 240. In some embodiments, the cutter 240 includes a blade on a carrier 242 that is movable with respect to the web of fabric 212 while cutting the web of fabric 212. The cutter 240 cuts the web of fabric 212 to create a first component 222 of the fabric article 220 and a second component 224 of the fabric article 220. As illustrated, in some embodiments, the cutter 240 cuts the web of fabric 212 to create one or more additional components 226 of the fabric article 220.
In some embodiments, the cutter 240 is controlled by the controller 150. In an example, a sensor associated with the cutter 240 detects a feature of the web of fabric 212, such as the printed design 223 or a fiducial on or in the web of fabric 212. The controller 150 uses information of the detected feature to direct the cutter 240 to cut the web of fabric 212 at a specific location of the web of fabric 212.
As illustrated, in embodiments in which the printer 230 has printed the design 223 onto the web of fabric 212, the first component 222 may include the portion of the web of fabric 212 on which the design 223 has been printed. Moreover, the cutter 240 creates the first component 222 by cutting the web of fabric 212 around the design 223.
In some embodiments, the web of fabric 212 includes a preexisting design—such as woven into, or printed onto, the web of fabric 212—before the web of fabric 212 is unwound onto the work surface 210. In such embodiments, the cutter 240 may create the first component 222 by cutting the web of fabric 212 around the design 223 even though the printer 230 did not print the design 223.
The portion of the web of fabric 212 that is not part of any component that is created by cutting with the cutter 240 is a web of remainder fabric 216. After cutting the components 222, 224, 226, the web of remainder fabric 216 is removed from the work surface 210 while the components 222, 224, 226 are maintained on the work surface 210. In embodiments in which the work surface 210 is configured to hold the fabric, the components 222, 224, 226 are maintained on the work surface 210 by the holding mechanism of the work surface 210, such as by the electrostatic plate or vacuum assembly described above. In some embodiments, the web of remainder fabric 216 is removed from the work surface 210 by winding the web of remainder fabric 216 onto a roller 215. In some embodiments, the removal of the web of remainder fabric 216 from the work surface 210 is controlled by the controller 150.
Then the components 222, 224, 226 are transported to station 203, which includes an adhesive applicator 250. In some embodiments, the adhesive applicator 250 includes a dispensing nozzle on a carrier 252 that is movable with respect to the fabric on the work surface 210 while dispensing an adhesive 254 onto the fabric. As illustrated, the adhesive applicator 250 applies the adhesive 254 to the second component 224. Additionally, or alternatively, in some embodiments, the adhesive applicator 250 applies the adhesive 254 to the first component 222. Additionally, or alternatively, in some embodiments, the adhesive applicator 250 applies the adhesive 254 to one or more of the additional components 226.
In some embodiments, the adhesive 254 is applied in the form of a liquid deposited onto the component 222, 224, or 226. In some embodiments, the adhesive 254 permeates at least partially into the fabric of the component 222, 224, or 226. In some embodiments, the adhesive 254 at least partially remains on a surface of the fabric of the component 222, 224, or 226. In some embodiments, the adhesive 254 is configured to be cured by any one or more of applying pressure, applying heat, applying moisture, exposing the adhesive to ambient conditions, or waiting for a predetermined duration of time. In some embodiments, the adhesive 254 is deposited onto the component 222, 224, or 226 in one or more of a continuous line, a non-continuous line, one or more droplets, a single line, or multiple lines. In some embodiments, lines or droplets may be deposited onto the component 222, 224, or 226 according to one or more of uniform shape, uniform size, uniform separation between adjacent droplets, varying shape, varying size, or varying separation between adjacent droplets. In some embodiments, the adhesive 254 is deposited onto the component 222, 224, or 226 in a pattern tailored according to any one or more of a desired seam size, a desired seam strength, or a desired accommodation of stretch of the component 222, 224, or 226.
In some embodiments, the adhesive applicator 250 is controlled by the controller 150. In an example, a sensor associated with the adhesive applicator 250 detects a feature of the fabric, such as the printed design 223, a fiducial on or in the fabric, or outline(s) of the component(s). The controller 150 uses information of the detected feature to direct the adhesive applicator 250 to apply the adhesive 254 at a specific location of the fabric.
Then the components 222, 224, 226 are transported to station 204, which includes a robot 260 that is used to position the first component 222 onto the second component 224. Station 204 includes an auxiliary robot 270 that is used to position the first component 222 onto the second component 224. Examples of the robot 260 and the auxiliary robot 270 are described below with respect to

In some embodiments, the heater may be omitted.
In some embodiments, the adhesive 254 is cured at a curing station 205. After the first component 222 is positioned onto the second component 224, the components 222, 224 are transported to the curing station 205. In an example, the curing station 205 may include curing apparatus 290, such as a heat press, a roller dryer, or a conveyor dryer, which is used to cure the adhesive 254 and bond the first component 222 to the second component 224. In some embodiments, the curing apparatus 290 cures the adhesive 254 through the application of one or more of heat, pressure, or moisture.
In some embodiments, the curing apparatus 290 at the curing station 205 is controlled by the controller 150. In an example, a sensor associated with the curing apparatus 290 detects a feature of the fabric, such as the printed design 223, a fiducial on or in the fabric, or the outline(s) of the component(s). The controller 150 uses information of the detected feature to direct the curing apparatus 290 to apply the necessary heat and/or pressure to the combined first and second components 222, 224.
In some embodiments, the adhesive 254 may be cured without necessitating the application of pressure and/or heat. In such embodiments, the head 264 of the robot 260 may omit a heater, a head of the auxiliary robot 270 may omit a heater, and/or the curing station 205 may be omitted. Alternatively, at least one heater or the curing station 205 may be present, but unused. In an example, the system 200 may be configured to manufacture fabric articles 220 using an adhesive that requires the application of pressure and/or heat for curing, and may be configured to manufacture fabric articles 220 using an adhesive that does not require the application of pressure and/or heat for curing.
Then the components 222, 224, 226 are transported to station 206, at which the additional components 226 are assembled onto the combined first and second components 222, 224.

Accordingly, embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, embodiments described herein may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.
Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
Computer program code for carrying out operations for embodiments of the present disclosure may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
Aspects of the present disclosure are described herein with reference to flowchart illustrations or block diagrams of methods, apparatuses (systems), and computer program products according to embodiments of the present disclosure. It will be understood that each block of the flowchart illustrations or block diagrams, and combinations of blocks in the flowchart illustrations or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the block(s) of the flowchart illustrations or block diagrams.
These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other device to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the block(s) of the flowchart illustrations or block diagrams.
The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process such that the instructions which execute on the computer, other programmable data processing apparatus, or other device provide processes for implementing the functions/acts specified in the block(s) of the flowchart illustrations or block diagrams.
The flowchart illustrations and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart illustrations or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order or out of order, depending upon the functionality involved. It will also be noted that each block of the block diagrams or flowchart illustrations, and combinations of blocks in the block diagrams or flowchart illustrations, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
It is contemplated that elements and features of any one disclosed embodiment may be beneficially incorporated in one or more other embodiments. While the foregoing is directed to embodiments of the present disclosure, other and further embodiments of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
