Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to an automatic fabric loading and unloading system and its working method and intelligent management method. Background Technology

[0002] Currently, the fabric loading and unloading process in garment factories relies entirely on manual labor. The specific process is as follows: first, a roll of fabric is placed on a fabric inspection machine or a fabric loosening machine; then, an empty pallet is placed under the inspection machine or loosening machine, and the roll of fabric is loosened into a roll. After loosening, a forklift is used to transport the pallet and the roll of fabric together to the unloading area for resting (generally 24-48 hours). Next, the pallet and the rested fabric are lifted onto a fabric spreading machine, and the machine is operated to spread the fabric. After spreading, the empty pallet is retrieved and returned to the inspection machine or loosening machine for use. Currently, most of the workers in this job in garment factories are women. Because the aforementioned process requires 2-3 people to operate, and the fabric is relatively heavy, the labor intensity is high and there are dangers for female workers, making it difficult for garment factories to recruit workers. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide an automatic fabric loading and unloading system that can automatically, smoothly, and efficiently complete the unloading process of the fabric inspection machine and the loading process of the fabric laying machine, thereby reducing labor costs and labor intensity.

[0004] This invention provides an automatic fabric loading and unloading system, comprising an automatic fabric unloading system and an automatic fabric loading system. The automatic fabric unloading system includes a material rack, a first fork lifting mechanism, a pallet lifting mechanism, and a fabric inspection machine arranged sequentially. The pallet lifting mechanism includes a first drive source and a first conveying component, the first conveying component moving up and down under the drive of the first drive source. It also includes a pallet pushing and pulling mechanism arranged parallel to the pallet lifting mechanism. The pallet pushing and pulling mechanism includes a second drive source, the movable end of which is connected to a first pull plate. The first pull plate is connected to a first push plate via a guide shaft. The second drive source drives the first pull plate and the first push plate to move horizontally. A pallet is placed between the first pull plate and the first push plate. The automatic fabric loading system includes a material rack, a first fork lifting mechanism, a pallet lifting mechanism, and a fabric inspection machine arranged sequentially. The system comprises a material rack, a second fork lifting mechanism, a return mechanism, a pallet support frame, and a fabric spreading machine. The return mechanism includes a support part, a third drive source mounted on the support part, and a movable part that moves up and down under the drive of the third drive source. The movable part is respectively provided with a second conveyor and a fourth drive source. The fourth drive source drives a second pull plate to move horizontally to retrieve an empty pallet. The pallet support frame is located at the feeding end of the fabric spreading machine and includes a third conveyor. The end of the third conveyor away from the return mechanism is provided with a positioning plate. The material rack is used to place the pallet. Both the first and second fork lifting mechanisms include a lifting assembly and a lifting platform mounted on top of the lifting assembly. The lifting platform is equipped with retractable forks, and the forks are provided with a conveyor belt.

[0005] Preferably, a fourth conveying component is also provided on the ground between the fabric inspection machine and the pallet lifting mechanism.

[0006] Preferably, the height of the end of the third conveyor that is away from the return mechanism is adjustable.

[0007] Preferably, the pallet support frame further includes a check mechanism, which is disposed at one end of the third conveyor near the return mechanism. The check mechanism includes a mounting base and a stop block that is elastically rotatably connected to the mounting base. The stop block limits the position of the pallet located on the third conveyor.

[0008] Preferably, it further includes a rotating mechanism connected to the check mechanism, the rotating mechanism driving the check mechanism to rotate.

[0009] Preferably, the rotating mechanism and the anti-return mechanism are elastically rotatably connected.

[0010] Preferably, the reflux mechanism further includes a fifth drive source disposed on the movable part, and a fourth drive source fixing part that moves horizontally under the drive of the fifth drive source, the fourth drive source being disposed on the fourth drive source fixing part; the fourth drive source fixing part is also provided with a second push plate at one end near the tray support frame, the second push plate being used to push the anti-return mechanism to flip.

[0011] The present invention also provides a method for operating the aforementioned automatic fabric loading and unloading system, comprising the following steps:

[0012] Unloading: The material rack filled with empty pallets is moved to the designated position of the automatic fabric unloading system. A roll of fabric is placed on the fabric inspection machine. The first fork lifting mechanism picks up the empty pallet from the material rack and places it on the lifting platform of the first fork lifting mechanism. The first drive source of the pallet lifting mechanism operates, raising the first conveyor to its highest point. The first fork lifting mechanism moves the empty pallet onto the first conveyor. The first drive source drives the first conveyor to its lowest point, placing the empty pallet between the first push plate and the first pull plate of the pallet push-pull mechanism. Then, the second drive source pushes the empty pallet into the fabric inspection area of ​​the fabric inspection machine through the first push plate. The fabric inspection machine is started to inspect and inspect the fabric. The fabric falls into the empty pallet to form a full pallet. Then, with the cooperation of the pallet push-pull mechanism, the pallet lifting mechanism, and the first fork lifting mechanism, the full pallet is placed back on the material rack.

[0013] Fabric warming: After the material rack is filled with material trays, move the material rack to the fabric warming area for fabric warming.

[0014] Feeding: After the fabric has been proofed, the rack with the full material tray is moved to the designated position of the automatic fabric feeding system. The second fork lifting mechanism picks up the full material tray from the rack and places it on the lifting platform of the second fork lifting mechanism. The second fork lifting mechanism then moves the full material tray to the tray support frame to complete the feeding.

[0015] Material handling during the fabric laying process: During the operation of the fabric laying machine, the second fork lifting mechanism picks up the full material pallet onto the lifting platform;

[0016] Empty pallet removal: After the fabric spreading machine finishes spreading the fabric, the full pallet becomes an empty pallet. The return mechanism moves the empty pallet from the pallet support frame to above the second fork lifting mechanism. After the second fork lifting mechanism finishes loading the full pallet, it picks up the empty pallet and places it on the lifting platform, then puts the empty pallet back into the material rack. After the material rack is full of empty pallets, it moves the material rack to the fabric resting area or the designated position of the automatic fabric unloading system.

[0017] This invention also provides an intelligent management method for an automatic fabric loading and unloading system. This method employs the aforementioned automatic fabric loading and unloading system, a WMS system for information processing, and a control system. The automatic fabric loading and unloading system further includes a fabric resting area and a moving device. Identification tags are affixed to the material rack, fabric inspector, fabric spreading machine, and the fabric itself. Different serial numbers are affixed to different locations in the fabric resting area. The corresponding information for each identification tag and serial number is stored in the WMS system. The control system is connected to both the automatic fabric unloading system and the automatic fabric loading system, and the WMS system operates by controlling the control system. The method includes the following steps:

[0018] Scan the identification tags on the fabric according to the order sequence in the order information, and put the fabric that matches the order information into the fabric inspection machine;

[0019] The mobile device moves the material rack filled with empty pallets to the designated position of the automatic fabric unloading system. The WMS system binds the information of the material rack and the fabric inspection machine, and then controls the automatic fabric unloading system to perform the unloading operation through the control system.

[0020] When the first fork lifting mechanism places a full pallet into any layer of the rack, the WMS system collects information about the material on the full pallet and its layer, and binds the two together.

[0021] After the material rack is filled with material trays, the moving device moves the material rack to any position in the fabric warming area. The WMS system binds the material rack and the corresponding serial number of its position, and starts to calculate the fabric warming time until the fabric warming is completed.

[0022] The mobile device moves the rack containing the refurbished fabric to the designated position of the automatic fabric feeding system. The WMS system binds the information of the rack and the fabric spreading machine, and then controls the automatic fabric feeding system to perform the feeding operation through the control system.

[0023] After the material loading is completed and the empty pallet is placed back into the material rack, the WMS system clears the fabric information bound to the layer where the empty pallet is located.

[0024] Preferably, if all the fabrics placed on the rack belong to the same order, after all the fabrics have been loaded, the moving device will move the rack to any position in the fabric preparation area. The WMS system will bind the rack and the corresponding serial number of its position, and indicate that the rack is empty. The empty rack can then be moved to the designated position of the automatic fabric unloading system.

[0025] If all the fabrics placed on the rack belong to different orders, after some fabrics have been loaded, the moving device will move the rack to any position in the fabric preparation area. The WMS system will bind the rack and its corresponding position number and indicate that the rack is a stock rack. Subsequently, the stock rack needs to be moved again to the designated position of the automatic fabric loading system to complete other orders.

[0026] The advantages of this invention are,

[0027] 1. In the automatic fabric feeding system, the lowest point of the first conveyor is the ground, which facilitates docking with various types of fabric inspection machines or fabric loosening machines.

[0028] 2. In the automatic fabric feeding system, the seamless connection between feeding and empty pallet recovery is achieved through the cooperation between the fork lifting mechanism, the return mechanism and the pallet support frame, which greatly improves work efficiency.

[0029] 3. Through the coordination of the automatic fabric unloading system, the fabric resting area, and the automatic fabric feeding system, the entire operating system can automatically complete the pallet transfer during the feeding and unloading process, and operate under automatic or manual control. No manual lifting of heavy objects is required throughout the process; one person can complete the operation, reducing the labor intensity of workers and saving labor costs. Information is shared throughout the entire operation, laying the groundwork for the future development of Internet of Things (IoT) technology. Attached Figure Description

[0104] 104 Mobile devices Detailed Implementation

[0105] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0106] In the description of this invention, it should be noted that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Specifically, the vertical direction is defined as the Z-axis direction, the conveying direction of the pallet is the Y-axis direction, the direction perpendicular to the Z-axis and Y-axis is the X-axis direction, and the "horizontal direction" is the direction perpendicular to the Z-axis. Furthermore, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0107] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0108] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0109] like Figure 1 As shown, the automatic fabric loading and unloading system provided by this invention includes an automatic fabric unloading system 101, an automatic fabric loading system 103, and a fabric resting area 102 located between the two. During daily operation, the operator first places the fabric on the fabric inspection machine 1, then places an empty pallet under the inspection machine 1. The rested fabric is then transported to the resting area 102 via a moving device 104 for resting. After resting, the full pallet containing the rested fabric is placed into the fabric spreading machine 8, and the spreading machine 8 is then operated to spread the fabric. After spreading, the empty pallet is retrieved and returned to the inspection machine 1 for use. The moving device 104 can be an AGV (Automated Guided Vehicle) or a handcart. The automatic fabric unloading system 101 and the automatic fabric loading system 103 are described in detail below.

[0110] Automatic Fabric Feeding System

[0111] like Figure 2-4 As shown, the automatic fabric unloading system includes a material rack 5, a first fork lifting mechanism 4, a pallet lifting mechanism 3, and a fabric inspection machine 1 arranged in sequence, and also includes a pallet push-pull mechanism 6 arranged parallel to the pallet lifting mechanism 3. The fabric inspection machine 1 can also be replaced by a fabric loosening machine.

[0112] like Figure 2 As shown, the material rack 5 includes multiple sets of support rods 51 spaced apart along the Z-axis. Each set of support rods 51 includes two support rods 51 at the same height, and a tray can be placed on the two support rods 51. For easy movement, the bottom of the material rack 5 is also equipped with multiple casters, making it easy for operators to move the material rack 5 to the required area.

[0113] like Figure 2 and Figure 3 As shown, the first fork lifting mechanism 4 includes a frame 44, a lifting assembly 43, and a lifting platform 45 arranged sequentially from bottom to top. The lifting platform 45 is equipped with retractable forks 41, and a conveyor belt 42 is mounted on the forks 41. The motor driving the conveyor belt 42 can rotate in either the forward or reverse direction. When the motor drives the conveyor belt 42 to rotate, it can bring the pallet back or away from the forks 41, thus moving the pallet. Preferably, the movement directions of the forks 41 and the conveyor belt 42 are parallel to the Y-axis. The frame 44 can be an AGV (Automated Guided Vehicle) with its own drive unit, or it can be a trolley requiring manual drive, serving to adjust the position of the first fork lifting mechanism 4. The lifting assembly 43 is preferably a scissor lift device, but it can also be replaced by commonly used drive devices such as linear motors, cylinders, or hydraulic cylinders, used to drive the lifting platform 45 to move up and down along the Z-axis. In specific implementation, the first fork lifting mechanism 4 also includes a limiting block (not shown), and the material rack 5 can be inserted into the limiting block to ensure that the relative position between the first fork lifting mechanism 4 and the material rack 5 is fixed, which facilitates unloading and moving the pallet.

[0114] like Figure 5-7 As shown, there are two pallet lifting mechanisms 3, symmetrically arranged about the Y-axis and maintained at a certain distance from the fabric inspection machine 1 for easy manual operation. The pallet lifting mechanism 3 is connected to the first fork lifting mechanism 4, ensuring a fixed relative position for pallet transport. Each pallet lifting mechanism 3 includes a support part 31 extending along the Z-axis, a first drive source 32, and a first conveying component 33. The support part 31 is equipped with a guide rail 35 extending along the Z-axis, and the end of the first conveying component 33 is slidably connected to the guide rail 35 via a slider 36. The form of the first drive source 32 is not limited; it can be a linear drive device or a rotary drive device. When using a linear drive device, simply connecting the output end of the linear drive device to the slider 36 will drive the first conveying component 33 to move along the Z-axis. The linear drive device can be a linear motor, a cylinder, a hydraulic cylinder, etc. When a rotary drive device is used, it is connected to the slider 36, and its output end is connected to a gear. The support 31 also has a rack 34 extending along the Z-axis, which meshes with the gear. When the rotary drive device is working, the gear rotates, driving the rotary drive device, slider 36, and first conveyor 33 to move along the Z-axis. The rotary drive device can be a stepper motor or a rotary cylinder. The lowest point of the first conveyor 33's stroke is at the ground, facilitating docking with various types of fabric inspection or loosening machines.

[0115] like Figure 4 , 5As shown in Figure 7, the pallet push-pull mechanism 6 is disposed between the two pallet lifting mechanisms 3, and includes a main frame 61 and a second drive source 63 installed in the main frame 61. The main frame 61 is preferably a rectangular frame, which is connected to the first fork lifting mechanism 4 through a fixing part 62, thus ensuring that the relative position between the two is fixed and facilitating pallet transport. A height adjustment part 611 is provided at each of the four corners of the main frame 61. The second drive source 63 is specifically a linear drive device, such as a linear motor, cylinder, hydraulic cylinder, etc. The movable end of the second drive source 63 passes through the main frame 61 and is connected to the first pull plate 65. The first pull plate 65 is connected to the first push plate 64 through a guide shaft 66 extending along the Y-axis. The first pull plate 65 is located outside the main frame 61 near the fabric inspection machine, and the first push plate 64 is located inside the main frame 61 near the first fork lifting mechanism 4. The top height of both is higher than the height of the main frame 61, and the distance between them is greater than the width of the pallet. This arrangement creates a space between the first pull plate 65 and the first push plate 64 to accommodate the pallet. When the second drive source 63 drives the first pull plate 65 and the first push plate 64 to move along the Y-axis, the pallet located between them can move along the Y-axis under the pull of the first pull plate 65 or the push of the first push plate 64. Simultaneously, the first pull plate 65 and the first push plate 64 also limit the movement of the pallet, preventing it from shifting during movement. The distance between the first pull plate 65 and the first push plate 64 can be adjusted as needed to accommodate different fabric inspection machines or fabrics of different widths. Furthermore, two fourth conveyor members 2 are symmetrically arranged about the Y-axis and extending along the Y-axis on the ground between the fabric inspection machine 1 and the pallet lifting mechanism 3, with the pallet push-pull mechanism 6 located between the two fourth conveyor members 2. The fourth conveyor members 2 help the pallet move smoothly from the first conveyor member 33 to the fabric inspection area of ​​the fabric inspection machine 1, allowing the pallet to accurately receive the fabric. At the bottom of the fourth conveyor 2, there are also multiple height adjustment components 21. The height adjustment components 21 and the aforementioned height adjustment component 611 are specifically adjustable feet, which facilitates the adjustment of the relative height of the first conveyor 33 and the fourth conveyor 2. The consistency of their heights is beneficial for the movement of the pallet.

[0116] The first conveying component 33 and the fourth conveying component 2 are preferably flow strips, each of which consists of multiple rollers. These flow strips can reduce the resistance during pallet conveying and make the conveying process smoother. Those skilled in the art can also select other similar rolling conveying components as needed.

[0117] Automatic Fabric Feeding System

[0118] like Figure 8 and Figure 9As shown, the automatic fabric feeding system includes a material rack 5, a second fork lifting mechanism 4, a return mechanism 7, a pallet support frame 9, and a fabric spreading machine 8 arranged in sequence. The structures of the material rack 5 and the first fork lifting mechanism have been described previously. The structure of the second fork lifting mechanism 4 is the same as that of the first fork lifting mechanism, and therefore will not be repeated here.

[0119] like Figure 9 and Figure 10 As shown, there are two return mechanisms 7, symmetrically arranged about the Y-axis and maintained at a certain distance from the spreading machine 8 for easy manual operation. Each return mechanism 7 includes a support part 73 extending along the Z-axis, a top plate 231 on top of the support part 73, and a bottom plate 232 at the bottom of the support part 73. The support part 73 is connected to the second forklift lifting mechanism 4 via a connecting part 734, which can prevent the return mechanism 7 from shifting position during operation. Preferably, multiple height adjustment components 733 are also provided at the bottom of the bottom plate 732. The height adjustment components 733 are specifically adjustable feet, which facilitates adjustment of the overall height of the return mechanism 7. A third drive source 71 is installed on the support part 73. The movable end of the third drive source 71 passes through the top plate 731 and drives the movable part 711 to move along the Z-axis, that is, the movable part 711 is located above the top plate 731. The movable part 711 is provided with a second conveyor 76 and a fourth drive source 77. The movable end of the fourth drive source 77 is connected to a second pull plate 771, which can drive the second pull plate 771 to move along the Y-axis to retrieve the empty tray. The second pull plate 771 can be circular, square, trapezoidal, or other shapes, as long as it can easily abut against the edge of the tray. The forms of the third drive source 71 and the fourth drive source 77 are not limited; both can be common drive devices such as linear motors, cylinders, and hydraulic cylinders. To ensure that the movable part 711 does not deviate during its movement along the Z-axis, several guide shafts 72 are provided at the bottom of the movable part 711. The guide shafts 72 penetrate the top plate 731, thereby guiding the movement of the movable part 711.

[0120] To ensure the smooth delivery of the pallet to the fabric spreading machine 8 without affecting its flipping lever, a pallet support frame needs to be added to the feeding end of the machine. This support frame holds the pallet up, creating a height difference between the pallet and the machine, facilitating removal of the pallet after fabric spreading. Furthermore, the support frame also acts as a limiter, preventing the pallet from detaching due to the inertia of the machine's start and stop. Figure 9 and Figure 11As shown, there are two pallet support frames 9, which are symmetrically arranged about the Y-axis at the feeding end of the fabric spreading machine 8. Each pallet support frame 9 includes a third conveyor 94, which is in the shape of a straight line. The end of the third conveyor 94 away from the return mechanism 7 is provided with a positioning plate 91. The top height of the positioning plate 91 is greater than the upper surface height of the third conveyor 94. It can limit the full pallet entering the feeding end of the fabric spreading machine 8, which facilitates subsequent manual fabric feeding.

[0121] like Figure 11 As shown, preferably, the height of the end of the third conveyor 94 closest to the return mechanism 7 is fixed, while the height of the end furthest from the return mechanism 7 is adjustable. Specifically, the pallet support frame 9 further includes a height adjusting component 92 disposed at the end of the third conveyor 94 furthest from the return mechanism 7, and a bracket 93 disposed at the end of the third conveyor 94 closest to the return mechanism 7, both of which are mounted on the spreading machine 8. The height adjusting component 92 is specifically an adjustable foot cup. During operation, by adjusting the height adjusting component 92, the height of the end of the third conveyor 94 closest to the return mechanism 7 is made greater than the height of the end furthest from the return mechanism 7. Due to the height difference between the two ends of the third conveyor 94, under the second forklift lifting mechanism 4 or manual drive, the full pallet will automatically slide along the pallet support frame 9 under gravity until the full pallet abuts against the positioning plate 91, completing the loading process.

[0122] like Figure 11 and Figure 12 As shown, the pallet support frame 9 further includes a check mechanism 95, which is disposed at one end of the third conveyor 94 near the return mechanism 7, and its top height is greater than the height of the upper surface of the third conveyor 94. The check mechanism 95 includes a mounting base 952 and a stop 951 elastically rotatably connected to the mounting base 952. The rotation axis of the stop 951 is parallel to the X-axis direction, which can limit the pallet located on the third conveyor 94 in the Y direction. Specifically, a torsion spring or a spring-loaded hinge is provided between the mounting base 952 and the stop 951.

[0123] The stop block 951 includes an inclined surface 951a facing the return mechanism 7 and a vertical surface 951b facing the positioning plate 91. During the process of the second fork lifting mechanism 4 or manual movement of the full pallet to the pallet support frame 9, the full pallet exerts a pushing force on the stop block 951 through the inclined surface 951a. After being subjected to the force, the stop block 951 rotates downward, so the full pallet can smoothly pass through the check mechanism 95 and move onto the pallet support frame 9 until the full pallet is completely located on the third conveyor 94. The pushing force exerted by the full pallet on the stop block 951 disappears, and the stop block 951 resets under the action of the elastic reset force. During the fabric laying process, any one or both of the vertical surface 951b of the stop block 951 and the positioning plate 91 can play a Y-direction limiting role on the edge of the pallet, thereby effectively preventing the pallet from loosening due to the inertia of the start and stop of the fabric laying machine and thus leaving the pallet support frame 9.

[0124] To facilitate the subsequent return mechanism 7 in retrieving the empty pallet, the present invention also provides a rotating mechanism 96 connected to the check mechanism 95. The rotating mechanism 96 can drive the check mechanism 95 to rotate around the Y-axis so that the height of the check mechanism 95 is less than the height of the upper surface of the third conveyor 94, thereby allowing the pallet located on the third conveyor 94 to enter the second conveyor 76 without obstruction.

[0125] The rotating mechanism 96 includes a fixed base 963, a mounting plate 162, and a resilient rotating connector 961 disposed between the fixed base 963 and the mounting plate 162. The fixed base 963 is connected to the third conveyor 94 or the spreading machine 8. The mounting base 952 of the check mechanism 95 is fixedly connected to the mounting plate 162. The resilient rotating connector 961 is a spring-loaded hinge or a torsion spring. Accordingly, as... Figure 10 As shown, the reflux mechanism 7 also includes a fifth drive source 74 disposed on the movable part 711 and a fourth drive source fixing part 78 that moves along the X-axis direction under the drive of the fifth drive source 74. The fourth drive source 77 is disposed on the fourth drive source fixing part 78. A second push plate 781 is also provided at one end of the fourth drive source fixing part 78 near the tray support frame 9. Preferably, to prevent the fourth drive source fixing part 78 from shifting during movement, a guide rail 75 extending along the X-axis direction is also provided on the movable part 711, and the fourth drive source fixing part 78 is slidably connected to the guide rail 75 by a slider.

[0126] In specific implementation, the extension directions of the second conveying member 76 and the third conveying member 94 are both parallel to the Y-axis direction. Both are preferably flow strips, each of which consists of multiple rollers. This can reduce the resistance during pallet conveying and make the conveying smoother. Those skilled in the art can also choose other similar rolling conveying members or use a support frame with a smooth surface as needed.

[0127] [Work Methods]

[0128] The present invention also provides a method for operating the aforementioned automatic fabric loading and unloading system, comprising the following steps:

[0129] S1. Material feeding:

[0130] A) such as Figure 1 and Figure 2 As shown, the operator prepares and uses the mobile device 104 to transport the material rack 5 filled with empty pallets to the designated position of the automatic fabric feeding system 101, and then places a roll of fabric on the fabric inspection machine 1.

[0131] B) Remove the empty pallet from the rack: such as Figure 2 and Figure 3 As shown, the forks 41 of the first fork lifting mechanism 4 extend toward any empty pallet placed in the rack 5. After the forks 41 are below the empty pallet, the lifting assembly 43 rises, and the forks 41 lift the empty pallet upward. At this time, the conveyor belt 42 rotates. Then the forks 41 retract and take the empty pallet from the rack 5 onto the lifting platform 45 of the first fork lifting mechanism 4.

[0132] C) Transfer empty pallets: such as Figure 2-6 As shown, the first drive source 32 of the pallet lifting mechanism 3 operates, raising the first conveyor 33 to its highest point. The lifting assembly 43 descends, making the height of the empty pallet on the lifting platform 45 slightly higher than the height of the first conveyor 33. Then, the forks 41 extend in the direction of the first conveyor 33, and the conveyor belt 42 rotates, moving the empty pallet above the first conveyor 33. At this time, the lifting assembly 43 continues to descend, and the empty pallet is transferred onto the first conveyor 33.

[0133] D) Pushing an empty pallet: such as Figure 5-7 As shown, the second drive source 63 of the pallet push-pull mechanism 6 drives the first push plate 64 to move to one end of the main frame 61 near the first fork lifting mechanism 4. Then, the first drive source 32 drives the first conveyor 33 to descend to the lowest point, placing the empty pallet between the first push plate 64 and the first pull plate 65. Then, the second drive source 63 pushes the empty pallet to the fourth conveyor 2 through the first push plate 64 and enters the patching area of ​​the fabric inspection machine 1.

[0134] E) Fabric rolling: Start the fabric inspection machine 1 to inspect and roll the fabric. The fabric falls into the empty pallet to form a full pallet.

[0135] F) Fill the pallet with material: such as Figure 5-7 As shown, the second drive source 63 pulls the full material tray through the first pull plate 65, so that the full material tray moves onto the first conveyor 33, and the first drive source 32 works to raise the first conveyor 33 to the highest point;

[0136] G) Return the full pallet: as shown in the image Figure 2-6As shown, the lifting assembly 43 descends, making the height of the lifting platform 45 slightly lower than the height of the first conveyor 33. Then, the forks 41 extend towards the full pallet. After the forks 41 are below the full pallet, the lifting assembly 43 rises, and the forks 41 lift the full pallet upward. At this time, the conveyor belt 42 rotates. Then, the forks 41 retract, taking the full pallet from the rack 5 onto the lifting platform 45. Next, the forks 41 extend towards the rack 5, and the conveyor belt 42 rotates, putting the full pallet back onto the rack 5.

[0137] S2, Refreshing cloth:

[0138] like Figure 1 As shown, after the material rack 5 is filled with material trays, the material rack 5 is moved to the cloth-warming area 102 by the moving device 104 for cloth warming (let it stand for 24h-48h).

[0139] S3, Loading:

[0140] A) Retrieving a Full Material Pallet: After the fabric has been proofed, the material rack 5, filled with the full material pallet, is moved to the designated position of the automatic fabric feeding system 103 using the moving device 104. For example... Figure 3 and Figure 8 As shown, the forks 41 of the second fork lifting mechanism 4 extend toward the full pallet placed in the material rack 5. After the forks 41 are below the full pallet, the lifting assembly 43 rises and the forks 41 lift the full pallet upward. At this time, the conveyor belt 42 rotates. Then the forks 41 retract and take the full pallet from the material rack 5 onto the lifting platform 45 of the second fork lifting mechanism 4.

[0141] B) Loading: The lifting assembly 43 rises, making the height of the lifting platform 45 slightly higher than the height of the pallet support frame 9. Then the forks 41 extend in the direction of the pallet support frame 9, and the conveyor belt 42 rotates, moving the full pallet from the forks 41 to the pallet support frame 9. The full pallet arrives at the feeding end of the fabric spreading machine 8, completing the loading.

[0142] S4. Taking materials during the fabric laying process:

[0143] The fabric is threaded manually, and the fabric spreading machine 8 is started. During the operation of the fabric spreading machine 8, the second fork lifting mechanism 4 repeats step A) of S3 above to pick up the full material pallet 2 onto the lifting platform 45.

[0144] S5. Empty pallet:

[0145] A) Remove the empty pallet: (e.g.) Figure 8-10As shown, after the fabric spreading machine 8 finishes spreading the fabric, the full pallet becomes an empty pallet. The third drive source 71 of the return mechanism 7 drives the second conveyor 76 to move to the same height as the pallet support frame 9. Then, the fifth drive source 74 drives the fourth drive source fixing part 78 to approach the rotating mechanism 96. The second push plate 781 pushes the anti-return mechanism 95 to flip. At the same time, the fourth drive source 77 drives the second pull plate 771 to move along the Y-axis until the second pull plate 771 abuts against the edge of the empty pallet closest to the positioning plate 91. Then, the fourth drive source 77 drives the second pull plate 771 to move in the opposite direction, moving the empty pallet from the pallet support frame 9 to the second conveyor 76. Then, the third drive source 71 drives the second conveyor 76 to rise, moving the empty pallet above the second fork lifting mechanism 4.

[0146] B) Loading and empty pallet retrieval: The second fork lifting mechanism 4 repeats step B) of S3 above to complete loading; then the lifting assembly 43 rises, the forks 41 lift the empty pallet upwards, at this time the conveyor belt 42 rotates, then the forks 41 retract, taking the empty pallet onto the lifting platform 45; then the forks 41 extend toward the material rack 5, the conveyor belt 42 rotates, and the empty pallet is placed back onto the material rack 5;

[0147] C) After the material rack 5 is full of empty pallets, move the material rack 5 to the designated position in the fabric preparation area 102 or the automatic fabric feeding system 101 to reuse the empty pallets.

[0148] [Intelligent Management Methods]

[0149] This invention also provides an intelligent management method for an automatic fabric loading and unloading system. This method employs the aforementioned automatic fabric loading and unloading system, ERP system, WMS system for information processing, and control system. Identification tags are installed on the material rack, fabric inspection machine, fabric spreading machine, and fabric itself. Different serial numbers are located at different positions in the fabric exposure area. The corresponding information for each identification tag and serial number is stored in the WMS system. The ERP system imports order information into the WMS system. The control system is connected to the first fork lifting mechanism, pallet lifting mechanism, and pallet push-pull mechanism in the automatic fabric unloading system, and the second fork lifting mechanism and return mechanism in the automatic fabric loading system. The WMS system operates through the control system.

[0150] The method includes the following steps:

[0151] S1. Material feeding:

[0152] A) Scan the identification tags on the fabric according to the order sequence in the order information, and put the fabric that matches the order information into the fabric inspection machine; specifically, the identification tags are QR codes or RFID tags;

[0153] B) The moving device moves the material rack filled with empty pallets to the designated position of the automatic fabric unloading system. The WMS system binds the information of the material rack and the fabric inspection machine, and then controls the automatic fabric unloading system to perform the unloading operation through the control system.

[0154] C) When the first fork lifting mechanism places the full pallet into any layer of the rack, the WMS system collects information about the material on the full pallet and its layer, and binds the two together.

[0155] S2, Refreshing cloth:

[0156] Once the material rack is filled with material trays, the moving device moves the rack to any position in the fabric warming area. The WMS system binds the rack and its corresponding position number and starts calculating the warming time until the warming is complete. Different fabrics require different warming times, and all relevant data is recorded in the WMS system. The WMS system then confirms whether the warming time requirement has been met.

[0157] S3, Loading:

[0158] A) The moving device moves the rack containing the prepared fabric to the designated position of the automatic fabric feeding system. The WMS system binds the information of the rack and the fabric spreading machine, and then controls the automatic fabric feeding system to perform the feeding operation through the control system.

[0159] B) After the material loading is completed and the empty pallet is returned to the material rack, the WMS system clears the fabric information bound to the layer where the empty pallet is located.

[0160] S4, Circulation:

[0161] If all the fabrics placed on the rack belong to the same order, after all the fabrics have been loaded, the moving device will move the rack to any position in the fabric preparation area. The WMS system will bind the rack and the corresponding serial number of its position, and indicate that the rack is empty. The empty rack can then be moved to the designated position of the automatic fabric unloading system.

[0162] If all the fabrics placed on the rack belong to different orders, after some fabrics have been loaded, the moving device will move the rack to any position in the fabric preparation area. The WMS system will bind the rack and its corresponding serial number and indicate that the rack is a stock rack. The stock rack will then need to be moved to the designated position of the automatic fabric loading system to complete other orders.

[0163] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
