Description

Technical Field

[0001] This invention relates to the field of fabric rolling machine technology, and in particular to an automatic edge-aligning device for fabric rolling. Background Technology

[0002] During the fabric laying process of a fabric rolling machine, the rolled fabric is typically picked up by a guide gripper and placed on the machine. One end of the rolled fabric is then aligned with the designated position on the machine. This ensures that the edge of the rolled fabric can be laid on the corresponding table of the laying machine. Currently, this alignment is usually done manually. However, due to product requirements, when a piece of fabric is laid halfway, it is sometimes flipped and laid backwards. After this rotation, the position of the rolled fabric on the laying machine changes, requiring it to be moved again for alignment. Currently, this alignment is done manually. However, the rolled fabric itself is heavy, making manual alignment cumbersome, posing safety hazards, and inefficient. Asymmetrically placed rolled fabric can also cause crush damage to the rotating transmission components.

[0003] For example, publication number "CN211310284U" discloses "a fabric winding mechanism for a fabric winding machine," comprising: a winding roller for winding a fabric strip around its outer circumference to form a fabric roll; a support mechanism on which the winding roller is supported; a drive roller arranged parallel to the bottom of the winding roller for supporting the winding roller; and a drive mechanism connected to the drive roller for driving the drive roller to rotate. However, in practical applications, when rotation and re-laying are required, the fabric roll can only be manually removed for rotation, and the edges need to be realigned on the fabric winding machine. This operation is complex, laborious, poses safety hazards, is inefficient, and cannot guarantee the flatness of the fabric roll surface. Summary of the Invention

[0004] In view of the problems mentioned in the background art, such as tedious manual edge positioning, low efficiency, and easy compression of rotating parts, the present invention provides an automatic fabric roll edge alignment device, which can realize automatic rotation and reverse laying, and automatically adjust the position of the roll before and after rotation, so as to avoid the center of gravity of the roll from being misaligned with the rotation center during rotation, protect the rotating transmission parts from lateral overturning force, extend service life, and at the same time, can quickly perform edge alignment operation, protect the flatness of the roll surface, and improve work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An automatic fabric roll edge-aligning device, comprising a support frame, characterized in that it further comprises:

[0007] Transfer platform: mounted on a support frame, including a rotating module, the transfer platform rotating around the rotating module;

[0008] Fabric roll adjustment component: Set on the transfer platform, it supports the fabric roll at the end away from the transfer platform and drives the fabric roll to move along the fabric roll axis.

[0009] The transfer platform is equipped with a rotating module, which rotates the transfer platform and in turn drives the fabric roll to rotate. After rotation, the fabric roll is laid back. Due to the change in the positions of the two ends, it deviates from the placement position on the fabric roll machine, and the edge alignment position also changes accordingly. The fabric roll adjustment component can move axially again to drive the edge of the fabric roll to perform edge alignment operation, ensuring the accuracy of positioning. In addition, it can ensure the horizontal position of the fabric roll during the adjustment process, avoiding the tilting and wrinkling of the fabric roll caused by inconsistent operation at both ends during manual adjustment. Moreover, the edge alignment accuracy and uniformity are higher, improving the efficiency of edge alignment.

[0010] Preferably, the rotating module is positioned at the center of the transfer platform. Positioning the rotating module at the center ensures that its rotation center coincides with the platform's center, guaranteeing balanced forces on both sides during operation. When a roll of fabric is placed on the platform, the roll is adjusted using the roll adjustment assembly. This balances the forces on both sides of the rotating module during rotation. Even when the platform is idling (without a roll of fabric), the rotating module's central position ensures balanced forces on both sides, preventing forces deviating from the transfer axis from the internal transmission components. Furthermore, because the rotating module is at the center, once the roll adjustment assembly has adjusted the fabric's position, the center point of the roll, the center point of the transfer platform, and the rotation center of the rotating module coincide. Therefore, the weight and volume of the roll on both sides of the rotation center are essentially the same, preventing axial displacement due to unbalanced forces and ensuring accurate positioning of the roll.

[0011] Preferably, the rotating module is equipped with a central gear, and the support frame is equipped with a central rack. The central rack meshes with the central gear, and a pusher is connected to the central rack. The central gear can mesh with the central rack, and the pusher drives the central rack to move. Through meshing transmission, the central gear rotates, thereby driving the transfer platform and the fabric roll supported on it to rotate. The gear meshing has good stability, and the vertical support is good, which can ensure the stability of the transfer platform during rotation.

[0012] Preferably, the fabric roll adjustment assembly includes a fixed frame, on which a rolling wheel is rotatably connected. The rolling wheel is connected to a rotation source, and the rolling wheel abuts against the rolled fabric. The rolling wheel abuts against the rolled fabric, and the rotation source drives the rolling wheel to move, thereby causing the rolled fabric supported above to move.

[0013] Preferably, the fixing frame is provided with rollers on both sides, and the two rollers form a "V" shaped angle.

[0014] Preferably, the rotation source is positioned below the rolling wheel, with a drive pulley connected to the end of the rotation source. A synchronous belt connects the drive pulley, and a driven pulley is positioned at the end of the synchronous belt away from the drive pulley. The driven pulley is located at the end of the rolling wheel. Positioning the rotation source below the fixed frame and the rolling wheel above the fixed frame, with a drive pulley connected to the end of the drive source and a driven pulley on the rolling wheel, and the drive pulley and driven pulley connected by a synchronous belt, reduces the overall volume of the fabric roll adjustment assembly. Furthermore, positioning the rotation source below the fixed frame avoids interference during fabric roll support.

[0015] Preferably, a lifting module is connected to the support frame, and the lifting module drives the support frame to rise and fall.

[0016] Preferably, a positioning sensor is provided at the end of the transfer platform.

[0017] Preferably, the fabric roll adjustment assembly includes a synchronous sliding member, which is slidably connected to the transfer platform. The synchronous sliding member is connected to a driving member, and a synchronous sensor is provided on the support frame. When the synchronous sensor detects the end of the fabric roll, the driving member drives the synchronous sliding member to move.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) A rotating module is set on the transfer platform. The rotating module makes the transfer platform rotate, which in turn drives the roll of cloth to rotate. After the roll of cloth rotates, it is laid back. Due to the position of the two ends being reversed, it deviates from the placement position on the roll of cloth machine. Therefore, the edge alignment position also changes accordingly. The roll of cloth adjustment component can move axially again, driving the edge of the roll of cloth to perform the edge alignment operation, ensuring the accuracy of positioning. In addition, the horizontal position of the roll of cloth can be ensured during the adjustment process, avoiding the tilting and wrinkling of the roll of cloth caused by inconsistent operation at both ends during manual adjustment. Furthermore, the edge alignment accuracy and uniformity are higher, improving the efficiency of edge alignment.

[0020] (2) The automatic rotation function of the roll is realized through the transfer platform, thereby realizing the reverse laying of the roll machine. Before rotation, the roll is aligned with the rotation center to protect the rotation center from lateral overturning force.

[0021] (3) The roll of cloth is driven to move by the rolling wheel and the rotation source, and the stability of the support is ensured and the application range is expanded by the "V" shaped angle;

[0022] (4) By driving the synchronous sliding component through the driving component, the cloth roll adjustment component moves synchronously with the cloth roll when it is close to the end of the cloth roll, avoiding the end of the cloth roll from leaving the support point or the gap part from contacting the support point, thus ensuring the overall straightness of the cloth roll, so that the transmission of the other cloth roll adjustment components is not affected.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1:

[0033] like Figure 1 As shown, an automatic edge-aligning device for a rolled fabric 6 includes a support frame 7 on which the rolled fabric 6 is mounted, and also includes: a transfer platform 1: mounted on the support frame and including a rotating module 11, the transfer platform 1 rotating around the rotating module 11; and a rolled fabric adjustment component 2: mounted on the transfer platform 1, supporting the rolled fabric 6 at the end away from the transfer platform 1 and driving the rolled fabric 6 to move along the axial direction of the rolled fabric 6.

[0034] A rotating module 11 is provided on the transfer platform 1. The rotating module 11 causes the transfer platform 1 to rotate, which in turn drives the roll of fabric 6 to rotate. After the roll of fabric 6 rotates, it is laid back. Due to the change in the position of the two ends, it deviates from the placement position on the roll of fabric machine, and the edge alignment position also changes accordingly. Therefore, the roll of fabric adjustment component 2 can move axially again to drive the edge of the roll of fabric 6 to perform edge alignment operation, ensuring the accuracy of positioning. In addition, it can ensure the horizontal position of the roll of fabric 6 during the adjustment process, avoiding the tilting and wrinkling of the roll of fabric 6 caused by inconsistent operation at both ends during manual adjustment. The edge alignment accuracy and uniformity are higher, and the edge alignment efficiency is improved. In this embodiment, there are three roll of fabric adjustment components 2. One roll of fabric adjustment component is set above the rotation center, and one is set at each end of the transfer platform to ensure the stability of the support. At the same time, the roll of fabric adjustment component can drive the roll of fabric to move axially, so that the forces on both sides of the rotating module are balanced and can cancel each other out before the roll of fabric is transferred. This eliminates the lateral overturning force on the rotating module, reduces the lateral force on the rotating module, and improves the service life of the internal transmission components of the rotating module.

[0035] like Figure 1 As shown, the rotating module 11 is positioned at the center of the transfer platform 1. This is a more optimized solution, although slight offsets due to installation errors in actual installation do not affect the performance. Positioning the rotating module at the center of the transfer platform ensures balanced forces on both sides during operation. When a roll of fabric is placed on the transfer platform, the roll is adjusted using the roll adjustment component. During rotation, the forces on both sides of the rotating module are balanced. Even when the transfer platform is idle (without a roll of fabric), the rotating module's central position ensures balanced forces on both sides during rotation, preventing forces deviating from the transfer axis from the internal transmission components. Furthermore, because the rotating module is at the center, after the roll adjustment component adjusts the roll's position, the center point of the roll, the center point of the transfer platform, and the rotation center of the rotating module coincide. Therefore, the weight and volume of the roll on both sides of the rotation center are essentially the same, preventing axial offset due to unbalanced forces and ensuring accurate positioning of the roll.

[0036] like Figure 2 As shown, a central gear 12 is provided on the rotating module 11, and a central rack 13 is provided on the support frame 7. The central rack 13 meshes with the central gear 12, and a pusher 15 is connected to the central rack 13. In this embodiment, the pusher 15 is a cylinder.

[0037] The transfer gear 12 can mesh with the transfer rack 13. The transfer rack 13 is driven to move by the pusher. The transfer gear 12 is rotated by the meshing transmission, which in turn drives the transfer platform 1 and the roll of cloth 6 supported on it to transfer. The gear meshing has good stability and the vertical support is good, which can ensure the stability of the transfer platform 1 during the rotation process.

[0038] like Figure 3 , 4 As shown, the fabric roll adjustment assembly 2 includes a fixed frame 21, on which a rolling wheel 22 is rotatably connected. The rolling wheel 22 is connected to a rotation source 23. The rolling wheel 22 abuts against the fabric roll 6. In this embodiment, the rotation source is a drive motor. Rolling wheels 22 are provided on both sides of the fixed frame 21, and the two rolling wheels 22 form a "V" shaped angle. The rotation source 23 is located below the rolling wheel 22. A drive pulley 24 is connected to the end of the rotation source 23. A synchronous belt 25 is connected to the drive pulley 24. A driven pulley 26 is provided at the end of the synchronous belt 25 away from the drive pulley 24. The driven pulley 26 is located at the end of the rolling wheel 22.

[0039] Roller 22 abuts against the rolled fabric 6. The rotation source 23 drives the roller 22 to move, thus moving the rolled fabric 6 supported above. A green velvet strip is provided on the surface of the roller 22 to ensure sufficient friction to provide rotational force for the rolled fabric 6. Roller 22s are provided on both sides of the fixing frame 21, forming a "V" angle. The rolled fabric 6 is generally cylindrical, and the "V" angle secures it between the two rollers 22, accommodating rolled fabric 6s of different diameters. The drive source is generally a drive motor. The two rollers 22 can rotate by connecting their respective drive motors, or the drive motors can be connected to the rollers... The motor is positioned between two rolling wheels 22, driving them to rotate synchronously via gear transmission. The rotation source 23 is positioned below the fixed frame 21, and the rolling wheels 22 are positioned above the fixed frame 21. A drive pulley 24 is connected to the end of the drive source, and a driven pulley 26 is positioned on the rolling wheel 22. The drive pulley 24 and the driven pulley 26 are connected together by a synchronous belt 25. The vertical positioning of the rolling wheels 22 and the drive source reduces the overall volume of the fabric roll adjustment assembly 2. Furthermore, positioning the rotation source 23 below the fixed frame 21 avoids interference during the lifting of the fabric roll 6.

[0040] like Figure 5 As shown, the lifting module 301 includes a lifting member 3 disposed on the support frame 7. The lifting member 3 is connected to a fixing plate 31. A vertical slide rail 32 is slidably connected on the fixing plate 31. The end of the vertical slide rail 32 is connected to the support frame 7.

[0041] The lifting component 3 can lift the support frame 7 upward, thereby driving the transfer platform 1 and the fabric roll adjustment component 2 to lift upward, so as to drive the fabric roll 6 to move in the receiving and feeding motion on the fabric roll machine. In addition, a receiving and feeding slide rail is set below the fixed plate 31 to move the entire transfer platform 1 away from or close to the fabric roll machine, so as to avoid interference with the fabric roll machine during the rotation of the fabric roll 6.

[0042] like Figure 6 As shown, a positioning sensor 4 is installed at the end of the transfer platform 1 to locate the position of the roll of fabric 6. Initially, if the positioning sensor 4 does not detect the roll of fabric 6, the roll of fabric 6 moves toward a position closer to the positioning sensor 4 until it is detected and stops. If the roll of fabric 6 is detected at the beginning, the roll of fabric 6 moves in the opposite direction. At the same time, to prevent the roll of fabric 6 from moving too much and causing one end of the roll of fabric 6 to detach from the support of the roll of fabric adjustment component 2, a positioning sensor 4 is added on each side. When the movement exceeds the specified position, it will stop to prevent the roll of fabric 6 from bending due to detachment from the support. The positioning sensor 4 includes a centering sensor and an edge sensor. The centering sensors are symmetrically arranged at both ends of the transfer platform 1, and the distance between them is slightly greater than the distance of the roll of fabric 6. When neither of the two centering sensors detects the roll of fabric 6, the centering ends and the transfer platform 1 rotates. After the rotation, the centering sensors stop working and the edge sensors start working. The position of the edge sensors is determined according to the edge position of the roll of fabric machine.

[0043] In this embodiment, the assembly and operation process of the automatic edge alignment device for the fabric roll 6 is as follows: In this embodiment, after the fabric roll 6 is laid out correctly on the fabric roll machine, the fabric roll machine stops working. At this time, the lifting component 3 drives the support frame 7 to rise, so that the three fabric roll adjustment components 2 abut against the top of the fabric roll 6, lifting the fabric roll 6. Then, driven by the feed rail, it moves away from the fabric roll machine. When it moves to a suitable position, the rotation source 23 in the fabric roll adjustment component 2 drives the rolling wheel 22 to center the fabric roll 6 according to the position detection of the centering sensor, so that the left and right sides of the central gear 12 are subjected to the same force. Then, the pushing component drives the central rack 13 to move, so that the meshing central gear 12 rotates. The central platform 1 drives the fabric roll 6 to rotate. After completion, the edge alignment sensor starts working. If the edge alignment sensor does not detect the roll 6, the roll 6 moves towards the position closer to the edge alignment sensor until it is detected and stops. If the roll 6 is detected at the beginning, the roll 6 moves in the opposite direction. After the edge alignment is completed, the feed slide rail drives the entire device to move towards the roll 6. The roll 6 adjustment component 2 passes through the clearance groove set on the roll 6 and comes to the top of the roll 6. At this time, the lifting component 3 descends, causing the roll 6 adjustment component 2 to disengage from the roll 6. Then, the positioning component on the roll 6 drives the roll 6 to make a fine adjustment and start the reverse laying operation, realizing the integrated operation of the forward and reverse laying of the roll 6 without manual intervention, realizing the function of one-click feeding.

[0044] Example 2:

[0045] like Figure 7 As shown, unlike Embodiment 1, the fabric roll adjustment assembly 2 in this embodiment includes a synchronous sliding member 5, which is slidably connected to the transfer platform 1. The synchronous sliding member 5 is connected to a driving member 51. The fabric roll 6 includes a gap portion 61. A synchronous sensor 52 is provided on the support frame 7. The axial length of the gap portion 61 is h, and the distance between the synchronous sensor 52 and the fabric roll adjustment assembly 2 at the initial position is H. h=H, where h and H are equal is the optimal state. In reality, due to mechanical errors, sensing deviations, etc., some deviation can still achieve a smooth conveying effect.

[0046] During the edge adjustment process of the fabric roll 6, if the displacement of the fabric roll 6 is too large, or if the distance between the edge of the fabric roll 6 and the fabric roll adjustment component 2 is too small, the edge of the fabric roll 6 will detach from the support of the end fabric roll adjustment component 2, resulting in one end of the fabric roll 6 losing support and bending downwards. Simultaneously, due to fabric shrinkage, wrinkles, and edge alignment errors of the fabric roll machine during the winding process, the edges of each layer at the end of the fabric roll 6 may not align, resulting in numerous gaps between different layers (gap section 61). Gap section 61 has ample space for compression deformation, while the middle area of ​​the fabric roll 6 is relatively tight. When gap section 61 runs on the fabric roll adjustment component 2, the weight of the fabric roll 6 between the two fabric roll adjustment components 2 is relatively heavy, causing it to sag. At this time, the remaining fabric roll adjustment components 2, due to the non-coplanarity of the bending area and the transport path, cause the fabric roll 6 to become stuck and risk falling, thus limiting the displacement of the fabric roll 6 and reducing its applicable range. Therefore, a synchronous sliding mechanism is provided at the bottom of the fabric roll adjustment component 2. The moving part 5 and the synchronous sliding part 5 are slidably connected to the transfer platform 1. The synchronous sliding part 5 is connected to the driving part 51, which is a cylinder. The driving part 51 drives the roll cloth adjustment assembly 2 to slide relative to the transfer platform 1. A synchronous sensor can be set on the support frame 7, and the setting position is away from the rotation center. When the synchronous sensor 52 does not detect the roll cloth 6, the rotation source 23 on the roll cloth adjustment assembly 2 at this end stops working. The driving part 51 starts to push the synchronous sliding part 5 and drives the roll cloth adjustment assembly 2 to follow the synchronous movement of the roll cloth 6. The movement speed of the driving part 51 is the same as the movement speed of the roll cloth 6 driven by the other rotation sources 23, ensuring that the rolling wheel 22 and the roll cloth 6 do not produce relative displacement. This ensures that the end of the roll cloth 6 can always be supported, thereby improving the range of motion of the roll cloth 6 and ensuring the stability of the roll cloth 6 during movement. H=h is set so that the support assembly of the roll cloth 6 will not be supported on the gap 61, ensuring the overall straightness of the roll cloth 6 and making the conveying effect more stable.

[0047] In addition to the above embodiments, within the scope disclosed in the claims and specification of this invention, the technical features of this invention can be reselected and combined to form new embodiments. These can be achieved by those skilled in the art without creative effort. Therefore, these embodiments not described in detail in this invention should also be regarded as specific embodiments of this invention and within the protection scope of this invention.
