[0041] Reference will now be made to Figure 2 , Figure 2 is a schematic diagram of folding and sewing of a piece of cloth. The piece of cloth used in the present application is a kind of textile with symmetrical structure. Before sewing the piece of cloth, it needs to be folded along the center line of the piece of cloth. However, the traditional folding process is mostly completed manually, and the accuracy of folding the piece of cloth is limited, and after folding, the placement positions of the pieces of cloth also differ from each other. In this case, even if mechanical sewing equipment is used for sewing, due to the slight differences in the folded state and the placement posture of the pieces of cloth, the yield of finished products will decrease.

[0042] In order to solve the above problems, the first aspect of the present application provides a piece of cloth folding mechanism, using which the folding process of the piece of cloth can be efficiently and accurately realized, and consistent folded pieces of cloth are provided for the subsequent sewing process. In order to more clearly illustrate the structure of the piece of cloth folding mechanism, the piece of cloth folding mechanism will be introduced below in combination with the drawings.

[0043] For example, please refer to Figure 1As shown, an embodiment of the present application relates to a piece folding mechanism 10. The piece folding mechanism 10 comprises a base plate 100, a piece dragging component 200, a piece folding pressing component 300 and a piece folding component. The base plate 100 and the piece folding component are installed on a rack. The piece dragging component 200 and the piece folding pressing component 300 are installed on the base plate 100. The base plate 100 is used to carry the piece 40. The piece dragging component 200 can drag the piece 40 at a set initial position on the base plate 100 to a set fixed position. The piece folding pressing component 300 can press one side of the piece 40 at the fixed position. The piece folding component can clamp the other side of the piece 40 at the fixed position and pull the other side of the piece 40 to a set folding position to form a fold.

[0044] The piece folding mechanism 10 further comprises a program controller. The program controller is used to adjust the set position information according to the size of the piece. By selecting the corresponding model of the piece in the program controller, the piece dragging component 200, the piece folding pressing component 300 and the piece folding component can match the corresponding movement, pressing and folding paths to adapt to pieces of different sizes.

[0045] In some embodiments, the piece dragging component 200 comprises a piece dragging member 210 and a horizontally arranged first guide rail 220. The first guide rail 220 is arranged on the base plate 100. The piece dragging member 210 has a lifting function and can clamp the piece on the base plate 100. The piece dragging member 210 is movably connected to the first guide rail 220 and can move along the first guide rail 220 to drag the pressed piece 40 from the initial position to the set fixed position.

[0046] In some embodiments, the piece dragging component 200 comprises a first lifting component 211. The first lifting component 211 is used to realize the lifting function of the piece dragging member 210.

[0047] In some embodiments, the piece dragging component 200 comprises a first telescopic component 230. The first telescopic component 230 is used to extend or retract the piece dragging member 210. The piece dragging member 210 used in the present application has a large size. By arranging the first telescopic component 230 for extending or retracting the piece dragging member 210, the piece dragging member 210 can be retracted after the piece dragging process is completed, leaving more space for other devices, which helps to make the layout of the piece folding mechanism more compact.

[0048] In some embodiments, the telescopic component is a rotary air cylinder, which is used to control the extension or retraction of the piece dragging member 210.

[0049] In some embodiments, the folding and holding component 300 includes a fixing member, a second connecting plate, and a horizontally disposed second guide rail 321. The second guide rail 321 is disposed on the second connecting plate, and the fixing member is movably connected to the second guide rail 321. The fixing member can be raised and lowered to compress and secure one side of the panel 40 at a predetermined fixed position along its centerline.

[0050] The thickness of the fixing member used in this application is less than 1 cm, thereby reducing the folding error caused by the fixing member's thickness. When setting the material pressing position of the fixing member in this application, one side of the fixing member is fixed along the centerline of the cutting piece 40, and the fixing member does not cross the centerline of the cutting piece 40. This setting can effectively improve the folding accuracy.

[0051] In some embodiments, the folding press 300 further includes a horizontally disposed third guide rail 323. The third guide rail 323 is disposed on the second guide rail 321, and the orientation of the third guide rail 323 is perpendicular to the orientation of the second guide rail 321. The rear fixing member 312 is movably connected to the third guide rail 323, and the extension length of the rear fixing member 312 can be controlled by moving on the third guide rail 323.

[0052] In some embodiments, the folding pressing member 300 further includes a first connecting plate 330 . The first connecting plate 330 is located below the bottom plate 100 , and the second guide rail 321 is disposed on the first connecting plate 330 .

[0053] In some embodiments, the folding pressing member 300 further includes a guide member 322 arranged parallel to the second guide rail 321. The guide member 322 is arranged on the first connecting plate 330.

[0054] In some embodiments, the fixing member includes a front fixing member 311 and a rear fixing member 312. The front fixing member 311 is used to press the front end of the cut piece, and the rear fixing member 312 is used to press the rear end of the cut piece.

[0055] In some embodiments, the fixing member includes a second lifting member 313. The two second lifting members 313 are respectively connected to the front fixing member 311 and the rear fixing member 312, and the lifting and lowering movements of the front fixing member 311 and the rear fixing member 312 are independently controlled by the two second lifting members 313.

[0056] In some embodiments, the fixing member further includes a second telescopic component 314. The second telescopic component 314 is connected to the front fixing member 311, and the second telescopic component 314 can control the extension length of the front fixing member 311 to match the panels 40 of different sizes.

[0057] In some embodiments, the folding member includes a first clamping member and a horizontally disposed fourth guide rail 420. The first clamping member can move horizontally along the fourth guide rail 420 to clamp the panel 40 at a set fixed position and perform the folding operation.

[0058] In some embodiments, the first clamping component includes a first upper clamping plate 411 and a first lower clamping plate 412 that can be lifted and lowered.

[0059] In some embodiments, the first clamping member further includes a third lifting member 413. The two third lifting members 413 are respectively connected to the first upper clamping plate 411 and the first lower clamping plate 412, and the lifting and lowering movements of the first upper clamping plate 411 and the first lower clamping plate 412 are independently controlled by the two third lifting members 413.

[0060] When performing the clamping operation, the first lower clamping plate 412 and the first upper clamping plate 411 will first be raised and lowered to a set height to ensure that the cut piece 40 can enter the middle area of ​​the first lower clamping plate 412 and the first upper clamping plate 411. Subsequently, the first clamping component moves along the fourth guide rail 420 to a set position so that the cut piece 40 is located between the first lower clamping plate 412 and the first upper clamping plate 411. Subsequently, the first upper clamping plate 411 descends to clamp the edge of one side of the cut piece 40. Subsequently, the first lower clamping plate 412 and the first upper clamping plate 411 will rise to a certain height simultaneously to avoid being blocked by the fixing parts. Subsequently, the first clamping component moves along the fourth guide rail 420 to a set folding position. Subsequently, the first lower clamping plate 412 descends to loosen the edge of the cut piece, allowing the cut piece 40 to be folded in half. After the folding is completed, the various components of the cut piece folding mechanism will be reset to their initial state.

[0061] In some embodiments, the first lower clamping plate 412 and the first upper clamping plate 411 are simultaneously raised to a height of 1 cm to 3 cm after clamping the edge of the panel 40. The raised height includes but is not limited to 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm or other parameters.

[0062] In a second aspect of the present application, there is provided an automatic sleeve sewing device comprising the above-mentioned cut piece folding mechanism and sewing components. Figure 5 , Figure 5 Schematic diagram of the structure of the automatic sleeve-buried sewing device in one embodiment of the present application. The sewing unit is mounted on a frame 30. The sewing unit can sew the folded pieces with a specified orientation in the sewing working area according to the set piece model.

[0063] In some embodiments, the sewing device further comprises a first robot 430 and a sewing machine 50. The first robot 430 is capable of transferring the folded-over garment piece 40 in the folded-over state to a sewing area of the sewing machine 50, and the sewing process of the garment piece 40 is completed by the sewing machine 50.

[0064] In some embodiments, the automatic sleeve-embedding sewing device further comprises a receiving plate 105, and the finished product after being sewn by the sewing machine 50 is transported to the receiving plate 105.

[0065] In some embodiments, the automatic sleeve-embedding sewing device further comprises a garment piece automatic feeding device 20. The garment piece feeding device 20 is used to provide the garment piece folding-over mechanism 10 with the garment piece 40. In order to more clearly illustrate the structure of the garment piece automatic feeding device 20, the garment piece automatic feeding device 20 will be described below in combination with the accompanying drawings.

[0066] For example, as shown in Figure 6 An embodiment of the present application relates to a garment piece automatic feeding device 20. The garment piece automatic feeding device 20 comprises a frame 30, a feeding mechanism 500, a separating mechanism, and a correcting mechanism 700. The separating mechanism has a first working area for separating and unfolding the garment piece 40, and the correcting mechanism 700 has a second working area for adjusting the posture of the garment piece 40.

[0067] The feeding mechanism 500 comprises a movable platform 510 for carrying the garment piece 40. The platform 510 is capable of moving the garment piece 40 on the surface thereof to the first working area of the separating mechanism for further separating and processing the garment piece 40.

[0068] The separating mechanism comprises a lifting assembly, a synchronous frame 620, and at least two second clamping components. The lifting assembly is connected to the frame 30 and is capable of lifting the uppermost garment piece 40 on the platform 510 in the first working area to separate the plurality of stacked garment pieces 40 one by one. The second clamping components are movably arranged on the synchronous frame 620 and are capable of moving horizontally on the synchronous frame 620 to adapt to the clamping of garment pieces 40 of different widths, so that the clamped garment pieces 40 are kept in an unfolded state. The synchronous frame 620 is movably connected to the frame 30 and is capable of moving the second clamping components to the vicinity of the garment piece 40 lifted by the lifting assembly, so that the second clamping components can clamp the garment piece 40. In addition, the synchronous frame 620 is also capable of transporting the garment piece 40 clamped by the second clamping components to the second working area of the correcting mechanism 700 for further correcting and processing the garment piece 40.

[0069] The correction mechanism 700 comprises an image collector 710 and an adjustment table 720. The image collector 710 is capable of analyzing the orientation of the cutting piece 40 on the adjustment table 720. The adjustment table 720 is capable of rotating the orientation of the cutting piece 40 located in the second working area, so that the cutting piece 40 maintains a set posture to enter the subsequent working procedure.

[0070] Referring to Figure 7 , Figure 7 FIG. 1 shows a schematic view of the feeding mechanism in an embodiment of the present application. In some embodiments, the feeding mechanism 500 comprises a placing table 510, a lifting guide 521 and a first driver 522. The placing table 510 is movably arranged on the frame 30, and the lifting guide 521 is arranged below the placing table 510. The first driver 522 is capable of driving the lifting guide 521 to move up and down, so that the placing table 510 moves up and down, and then the cutting piece 40 is transferred from the feeding position to the distributing mechanism.

[0071] In some embodiments, the lifting guide 521 is a screw rod. The first driver 522 is capable of driving the screw rod to rotate, so as to realize the up and down movement of the screw rod. The screw rod can be a ball screw or a trapezoidal screw rod.

[0072] In some embodiments, the placing table 510 is provided with a plurality of support rods 530 below. The support rods 530 can move up and down synchronously with the placing table 510 and support the placing table 510.

[0073] In some embodiments, the four support rods 530 are arranged in a square array below the placing table 510, so as to stably support the placing table 510.

[0074] In some embodiments, the feeding mechanism 500 further comprises a fixing table 540 connected with the frame 30. The fixing table 540 is provided with holes adapted to the lifting guide 521 and the support rods 530, so that the lifting guide 521 and the support rods 530 pass through the fixing table 540.

[0075] In some embodiments, the fixing table 540 is provided with bearings 550 at the ports of the holes for the support rods 530. The support rods 530 pass through the bearings 550 on the fixing table 540, so as to realize more stable movement and support effect.

[0076] In some embodiments, the first driver 522 is arranged on the fixing table 540.

[0077] Referring to Figure 8 , Figure 8Figure 6 is a schematic view of a partial structure of the lifting component in an embodiment of the present application. In some embodiments, the lifting assembly includes a pin 610 and a second driver. The pin 610 is perpendicular to the plane on which the table is located. The second driver is connected to the pin 610, and the second driver can drive the pin 610 to lower so that the pin 610 can pierce the first layer of the plurality of stacked pieces of film on the table 510. The second driver can also drive the pin 610 to rise so that the piece 40 pierced by the pin 610 can be lifted. After the second gripping component grips the piece 40, the second driver can continue to drive the pin 610 to rise so that the pin 610 can be separated from the piece 40.

[0078] In some embodiments, the position of the pin 610 is set relative to the first working area so that the pin 610 can pierce the middle section of the piece 40 on the first working area.

[0079] Referring to Figure 7, Figure 9 , Figure 9 Figure 8 is a schematic view of a partial structure of the film separating mechanism in an embodiment of the present application. In some embodiments, the second gripping component includes a gripping arm and a third driver. The gripping arm is movably mounted on the synchronization frame 620. The gripping arm is used to grab the piece 40 lifted by the lifting assembly. The third driver can drive the gripping arm to slide along the synchronization frame 620 so that the gripping arm can grab the piece 40 at a set width, thereby ensuring that the piece 40 can maintain an unfolded state and avoiding the piece 40 from being curled in the subsequent process. It can be understood that, in order to unfold the piece 40, the gripping arms of the two sets of second gripping components should be arranged on both sides of the lifting assembly to grab both sides of the piece 40 lifted.

[0080] In some embodiments, the gripping arm includes a second upper clamping plate 631, a second lower clamping plate 632, and a fourth lifting component 633. The fourth lifting component 633 can drive the second upper clamping plate 631 to move relative to the second lower clamping plate 632 to achieve clamping or releasing of the piece 40. At the same time, the second lower clamping plate 632 is set to have a preset height below the height of the piece 40 after being lifted, and the second upper clamping plate 631 is set to have a preset height above the height of the piece 40 after being lifted.

[0081] In some embodiments, in order to more efficiently and accurately carry out the unfolding and grabbing operations of the cutting piece 40, the initial positions of the two sets of second clamping components are relatively close to each other, so that when the synchronous frame 620 moves to the first working area, the two sets of second clamping components can be close to the lifting device located therebetween, avoiding the situation that the edges of the cutting piece 40 drop below the lower clamping plate due to the second clamping components being far away from the middle part of the cutting piece 40. At this time, after the cutting piece 40 is lifted and the synchronous frame 620 is moved to the position, it can be ensured that the cutting piece 40 is located in the middle of the upper and lower clamping plates, and the gradually unfolding of the cutting piece 40 can be realized by driving the clamping arms on the left and right sides to relatively move away from each other through the third driver. When the third driver drives the clamping arms to move to the set position, the second upper clamping plate 631 is driven to descend through the fourth lifting component 633, and the gradually clamping of the cutting piece 40 is completed. After the synchronous frame 620 moves the clamped cutting piece 40 to the second working area, the fourth lifting component 633 drives the second upper clamping plate 631 to reset, so that the cutting piece 40 is laid flat on the adjustment table 720. After the transfer of the cutting piece 40 is completed, the third driver drives the clamping arms to reset.

[0082] In some embodiments, the synchronous frame 620 has a horizontal fifth guide rail 621. The second clamping component further includes a guide rail connecting piece 634, and the clamping arm can be connected to the fifth guide rail 621 through the guide rail connecting piece 634 and move along the guide rail.

[0083] In some embodiments, the fifth guide rail 621 includes two parallel arranged screw rods. The two clamping components are respectively installed on different screw rods through the guide rail connecting piece 634.

[0084] In some embodiments, the fifth guide rail 621 includes two screw rods which are arranged adjacent to each other and face the same direction. The two clamping components are respectively installed on different screw rods through the guide rail connecting piece 634.

[0085] In some embodiments, the rack 30 further includes a horizontally aligned guide rail group 102 and a fourth driver. The two ends of the synchronous frame 620 are movably connected to the guide rail group 102. The fourth driver can drive the synchronous frame 620 to move along the guide rail group 102, so that the synchronous frame 620 approaches or moves away from the first working area and the second working area.

[0086] Please refer to Figure 10 , Figure 10 for the structural schematic diagram of the correction mechanism in an embodiment of the present application. In some embodiments, the image collector 710 is located on the expansion support 104 of the rack 30, so that the image collector 710 can have a larger image collection range.

[0087] Please refer to Figure 11 , Figure 11This is a partial structural diagram of a correction mechanism in one embodiment of the present application. In some embodiments, the adjustment platform 720 is located on the table 103 of the frame 30. The adjustment platform 720 in this application is a circular disk. By rotating the adjustment platform 720, the orientation of the cut piece 40 located on its surface can be adjusted. To prevent the center position of the cut piece 40 from shifting during rotation, the center of the adjustment platform 720 is designated as the second working area.

[0088] In some embodiments, the projection direction of the line connecting the center of the adjustment platform 720 and the center of the pin 610 on a horizontal plane is parallel to the guide direction of the guide rail assembly 102. In this case, after the grabbing assembly grabs the panel 40, it only needs to drive the synchronization frame 620 to move along the guide rail assembly 102 to align the middle section of the panel 40 with the second working area, that is, align the center of the panel 40 with the center of the circle, thereby preventing the panel 40 from shifting during rotation.

[0089] In some embodiments, the height difference between the surface of the adjustment platform 720 and the second lower clamping plate 632 is set to be less than 3 cm to prevent the cutting piece 40 from curling again after the second clamping member releases the cutting piece 40.

[0090] In some embodiments, the correction mechanism 700 further includes an annular ring 721. The annular ring 721 is located outside the adjustment platform 720 and serves to reinforce the outer ring.

[0091] In some embodiments, the image collector 710 further includes an image analysis component that analyzes the data collected by the image collector 710 to determine the orientation of the cut piece 40. If the orientation of the cut piece 40 does not meet the set requirements, the image analyzer controls the rotation of the adjustment stage 720 to adjust the cut piece 40 to the set orientation.

[0092] In some embodiments, the correction mechanism 700 further includes a rotation shaft 730 and a fifth actuator 740. The rotation shaft 730 is connected below the adjustment platform 720. The fifth actuator 740 drives the rotation shaft 730 to rotate, thereby rotating the adjustment platform 720 to adjust the orientation of the cut piece 40.

[0093] In some embodiments, the correction mechanism 700 further includes a coupling 760 , which connects the fifth driver 740 and the rotating shaft 730 .

[0094] In some embodiments, the correction mechanism 700 further includes a mounting plate 751 and a support base 752 connected to the frame 30. The support base 752 and the fifth driver 740 are disposed on the mounting plate 751.

[0095] In some embodiments, the automatic fabric piece feeding device 20 further comprises a second mechanical arm 770. The second mechanical arm 770 is used to move the fabric piece adjusted by the adjusting mechanism to the sewing device.

[0096] In some embodiments, the automatic fabric piece feeding device 20 further comprises a power switch. The power switch is used to control the power supply of the automatic fabric piece feeding device 20.

[0097] In some embodiments, the automatic fabric piece feeding device 20 further comprises a control console. The control console is used to control the automatic fabric piece feeding device 20 to start the working process according to the set parameters, or control the components of the automatic fabric piece feeding device 20 to reset to the initial position, or stop all processes of the automatic fabric piece feeding device 20.

[0098] Example 1

[0099] This example illustrates one of the working processes of the fabric piece folding mechanism 10 of the present application for dragging, fixing and folding the fabric piece 40.

[0100] The operator places the fabric piece 40 at the initial position set on the base plate 100 and starts the working process program of the fabric piece folding mechanism 10 corresponding to the size of the fabric piece 40. The working process of the fabric piece folding mechanism 10 includes a fixing process, a folding process and a sewing process.

[0101] Firstly, the fabric piece folding mechanism 10 starts the dragging process. The dragging process is as follows: the first telescopic component 230 extends the dragging component 210, the dragging component 210 moves along the first guide rail 220 to the set initial position, and the first lifting component 211 drives the dragging component 210 to descend and press the fabric piece 40 at the initial position. The dragging component 210 moves the fabric piece 40 along the first guide rail 220 to the set fixed position.

[0102] After the dragging process, the fabric piece folding mechanism 10 starts the fixing process. The fixing process is as follows: the fixing component moves along the second guide rail 321 to the set fixed position. According to the size of the fabric piece 40, the rear fixing component 312 moves along the third guide rail 323 to the set position, and the second telescopic component 314 controls the front fixing component 311 to extend to the set position. The second lifting component 313 drives the front fixing component 311 and the rear fixing component 312 to descend and fix the left side of the fabric piece along the center line of the fabric piece 40.

[0103] After the fixing process, the folding mechanism 10 will start the folding process. The folding process is as follows: the third lifting component 413 drives the first lower clamp plate 412 and the first upper clamp plate 411 to a set height, the first clamping component moves along the fourth guide rail 420 to a set position, and the right edge of the cutting sheet 40 is located in the middle of the first lower clamp plate 412 and the first upper clamp plate 411. The third lifting component 413 drives the first upper clamp plate 411 to descend and press the cutting sheet 40, and drives the first lower clamp plate 412 to ascend synchronously with the first upper clamp plate 411 to a set height. The first clamping component moves along the fourth guide rail 420 to a set folding position, the third lifting component 413 drives the first lower clamp plate 412 to descend to release the cutting sheet 40, and the folding process is completed. The components of the cutting sheet folding mechanism 10 are reset.

[0104] Embodiment 2

[0105] This embodiment illustrates one of the working processes of the cutting sheet automatic feeding device 20 for feeding, distributing and correcting the cutting sheet 40.

[0106] The worker places the cutting sheet combination stacked by multiple cutting sheets 40 on the designated area of the placement table 510, sets the cutting sheet model and the cutting sheet quantity through the control console, and starts the working process of the cutting sheet automatic feeding device 20. The working process of the cutting sheet automatic feeding device 20 includes the feeding process, the distributing process and the correcting process.

[0107] After the working process is started, the cutting sheet automatic feeding device 20 first performs the feeding process once. The feeding process is as follows: the first driver 522 drives the placement table 510 to rise to the first working area, and the feeding process is completed.

[0108] After the feeding process, the cutting sheet automatic feeding device 20 repeats the steps of the distributing process and the correcting process according to the set cutting sheet quantity to complete the processing of all feeding cutting sheets.

[0109] The distribution process is as follows: the second driver drives the pins 610 to descend to a set height, so that the pins 610 hook the middle section of the piece 40. The second driver drives the pins 610 to ascend to a set height, so that the piece 40 is lifted to a set height. The fourth driver drives the synchronization frame 620 to move to a set position, so that the piece 40 is located between the second upper clamp plate 631 and the second lower clamp plate 632 of the clamping arm. The third driver drives the clamping arm to move to a set position, so that the piece 40 is gradually unfolded under the drive of the second lower clamp plate 632. The fourth lifting component 633 drives the second upper clamp plate 631 to descend, so that the two ends of the piece 40 are clamped. The second driver drives the pins 610 to ascend to a set height, so that the pins 610 are separated from the piece 40. The fourth driver drives the synchronization frame 620 to move to a set position, so that the middle section of the clamped piece 40 is aligned to the second working area. The fourth lifting component 633 drives the second upper clamp plate 631 to ascend, so that the two ends of the piece 40 are released, and the piece 40 is laid flat on the second working area of the arranging table. The fourth driver drives the synchronization frame 620 to reset, and the third driver drives the clamping arm to reset, completing a single distribution process.

[0110] The correction process is as follows: the image collector 710 collects the orientation of the piece 40 located in the second working area. The orientation of the piece 40 is analyzed by the image analysis element, and the fifth driver 740 is controlled to drive the adjusting table 720 to rotate, so that the piece 40 is adjusted to a set orientation, completing the correction process.

[0111] The second robot 770 moves the corrected piece 40 from the second working area to the sewing device whenever a correction process is completed.

[0114] The steps of the feeding, distribution, and correction processes of the piece 40 of the piece automatic feeding device 20 of this embodiment are substantially the same as those of Embodiment 2, except that the second robot 770 moves the corrected piece 40 from the second working area to the initial position on the bottom plate.

[0115] The steps of the dragging, fixing, and folding processes of the piece 40 of the piece folding mechanism 10 of this embodiment are substantially the same as those of Embodiment 1, except that the piece 40 is placed at the initial position on the bottom plate through the piece automatic feeding device 20, and the dragging, fixing, and folding processes are automatically started.

[0116] After the folding process, the automatic sleeve burying sewing equipment starts the sewing process. The sewing process is as follows: the first mechanical arm 430 transfers the folded cutting piece 40 in the set position to the sewing machine 50 in a folded posture, and the sewing machine 50 performs sewing processing on the cutting piece 40.

[0117] After the sewing process, the sewn cutting piece is transferred to the receiving plate 105.
