Description

Technical Field

[0001] This invention relates to the field of fabric laying machine technology, and in particular to an automatic edge alignment and correction system and method for fabric rolls. Background Technology

[0002] Currently, the fabric feeding of the fabric spreading machine requires manual feeding and lacks an automatic correction function. Therefore, there are two problems with the fabric feeding of the fabric spreading machine. First, if the fabric roll is not placed properly when it is loaded onto the feeding trolley, the position needs to be manually corrected when the fabric spreading machine is laying the fabric. Second, when the fabric needs to be reversed, after the transfer mechanism removes the fabric roll from the spreading machine and rotates it 180°, when it is loaded onto the spreading machine again, there is a problem that the fabric roll is too biased on one side, requiring manual correction. This increases the labor intensity of the fabric spreading operator and reduces work efficiency. Summary of the Invention

[0003] The present invention mainly addresses the problem that the feeding of fabric on a cloth-laying machine requires manual correction of the position, which increases the labor intensity of workers and results in low work efficiency. It provides an automatic edge alignment and correction system and method for cloth rolls.

[0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: an automatic edge alignment and correction system for fabric rolls, comprising,

[0005] The correction platform includes several correction components that move the fabric roll;

[0006] The correction platform is rotatably mounted on the correction platform, and the correction platform drives the correction platform to move horizontally and vertically.

[0007] The correction detection unit includes a correction sensor that is correspondingly set on the correction component to detect the state of the rolled fabric, and a correction auxiliary sensor set at the edge of the correction platform.

[0008] The control unit controls the movement of the fabric roll to perform edge correction based on the information of the fabric roll edge detected by the correction sensor and the correction auxiliary sensor.

[0009] This invention detects the edge information of the fabric roll and uses a correction platform to automatically correct its deviation, reducing the labor intensity of fabric laying workers and improving laying efficiency. This invention only requires the addition of an automatic correction system to the existing material loading and transfer mechanism, without major modifications, making installation convenient and manufacturing costs low.

[0010] As a preferred embodiment, the correction components located on both sides of the web-correcting assembly have correction sensors positioned on the side furthest from other correction components. Preferably, the invention provides three correction components, positioned on both sides and in the middle, providing good support and movement for the rolled fabric. Three correction sensors are provided corresponding to each correction component, with each sensor corresponding to one component. The correction sensors on the sides are located on the side of the correction component furthest from other correction components, allowing for more accurate identification of whether the rolled fabric is on the correction component. The correction sensors are installed facing upwards to detect whether rolled fabric, i.e., the edge information of the rolled fabric, is placed on the correction platform.

[0011] As a preferred embodiment, the correction detection unit includes two correction auxiliary sensors spaced apart at the edge of the correction platform. This embodiment uses two correction auxiliary sensors, which are arranged at intervals on the same side of the correction platform edge. This eliminates the need to acquire fabric roll edge identification information, move the fabric roll until it can no longer be identified, and then reverse the movement, thus saving correction steps.

[0012] An automatic edge alignment and correction method for fabric rolls includes the following steps:

[0013] Information on the placement of the rolled fabric on the correction platform is obtained from the correction sensor;

[0014] After obtaining information that the roll of fabric has been placed, the edge information of the roll of fabric is obtained based on the correction auxiliary sensor;

[0015] Based on the edge information of the fabric roll, the corresponding correction information is sent to the correction platform until the correction completion signal sent by the correction auxiliary sensor is obtained, and then the completion signal is sent to the correction platform.

[0016] This invention detects the edge information of the fabric roll and controls the movement of the fabric roll by the correction component on the correction platform, thereby achieving automatic correction of the fabric roll, reducing the labor intensity of the fabric laying worker and improving the fabric laying efficiency.

[0017] As a preferred embodiment, the step of sending corresponding correction information to the correction platform based on the fabric roll edge information until the correction completion signal sent by the correction auxiliary sensor is obtained, and sending the completion signal to the correction platform includes:

[0018] If unidentified information is obtained at the edge of the roll, a first correction signal is sent to the correction platform to cause the correction component to move the roll in the first direction until the identified information at the edge of the roll is obtained, and a completion signal is sent to the correction platform.

[0019] If the edge recognition information of the rolled fabric is obtained, a second correction signal is sent to the correction component to cause the correction component to move the rolled fabric in the second direction until the edge recognition information of the rolled fabric is obtained. Then, a return signal is sent to the correction platform to cause the correction component to move the rolled fabric in the first direction until the edge recognition information of the rolled fabric is obtained. Finally, a completion signal is sent to the correction platform.

[0020] The first direction is opposite to the second direction.

[0021] If the correction assist sensor fails to detect the rolled fabric, and the control unit receives information indicating that the edge of the rolled fabric is not identified, it means that the rolled fabric deviates too much from the position of the correction assist sensor during placement. The control unit then moves the rolled fabric towards the assist sensor's position until the assist sensor detects the rolled fabric and obtains edge identification information. At this point, the fabric correction is complete, and rotation stops. Conversely, if the correction assist sensor detects the rolled fabric, and the control unit receives edge identification information, it means that the rolled fabric deviates too much from the sensor's position. The control unit then moves the rolled fabric inwards, away from the assist sensor's detection range, and repeats the correction operation, moving the rolled fabric towards the assist sensor's position again. Once the assist sensor detects the rolled fabric again and obtains edge information, the fabric correction is complete, and rotation stops.

[0022] As a preferred embodiment, the web correction detection unit includes two web correction auxiliary sensors spaced apart at the edge of the web correction platform. The step of sending corresponding web correction information to the web correction platform based on the fabric roll edge information, until a web correction completion signal is received from the web correction auxiliary sensors, includes:

[0023] If one roll edge recognition information and one roll edge unrecognized information are obtained, a completion signal is sent to the correction platform.

[0024] If two unidentified information of the edge of the roll are obtained, the first correction signal is sent to the correction platform to cause the correction component to move the roll in the first direction until one roll edge identification information is obtained, and a completion signal is sent to the correction platform.

[0025] If two roll edge recognition information are obtained, a second correction signal is sent to the correction component to cause the correction component to move the roll in the second direction until an unrecognized roll edge information is obtained, and a completion signal is sent to the correction platform.

[0026] The first direction is opposite to the second direction.

[0027] This solution, with two auxiliary correction sensors, allows for edge correction of the fabric roll by simply moving it to one side under three edge information conditions. This saves on operational steps and improves correction efficiency.

[0028] As a preferred embodiment, the return signal includes a delay signal. After receiving the delay signal, the correction platform will stop operating within a preset time and then cause the correction component to drive the roll of fabric to move in the first direction.

[0029] As a preferred embodiment, before obtaining the cloth roll placement information on the correction platform based on the correction sensor, if a cloth roll rotation signal is detected, the following steps are included: sending material picking information to the correction moving base, causing the correction moving base to move the correction platform to the material picking position to pick up the material, and then driving the correction platform to reset and rotate 180°.

[0030] Before performing edge correction on the roll of fabric, it is determined whether the roll of fabric needs to be rotated. If the roll of fabric needs to be rotated, the correction platform picks up the material, and after the material is picked up and reset, it is rotated 180°. After the roll of fabric is rotated, the edge correction operation of the roll of fabric continues.

[0031] As a preferred solution, if any correction sensor fails to detect fabric roll information during the correction process, the system will stop and issue an alarm. In this solution, all correction sensors are controlled by normally closed signals. If a correction sensor malfunctions during the correction process and fails to detect fabric roll as per the procedure, the system will immediately stop and issue an alarm to prevent fabric roll from falling due to sensor failure during the correction process.

[0032] Therefore, the advantages of this invention are: by detecting the edge information of the fabric roll, the fabric roll is automatically corrected by the laterally moving the correction platform, which reduces the labor intensity of the fabric pulling worker and improves the fabric pulling efficiency.

[0033] This invention only requires the addition of an automatic correction system to the original feeding and transfer mechanism, without major modifications. It is easy to install and has low manufacturing costs. Attached Figure Description

[0039] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0040] Example 1:

[0041] This embodiment describes an automatic edge alignment and correction system for fabric rolls, such as... Figure 3 As shown, it includes a correction platform, a correction moving base 2, a correction detection unit, and a control unit.

[0042] The correction platform 1 includes several correction components 3 for moving the cloth roll 5 and a rotating support beam 4. Preferably, there are three correction components 3, which are installed side by side on both sides and in the middle of the rotating support beam 4. The rotating support beam 4 is rotatably connected to the correction moving base 2.

[0043] like Figure 4 As shown, the web guiding assembly 3 includes a connecting column 6 and two rollers 7. The two rollers 7 are respectively disposed on both sides of the upper end of the connecting column 6. Both rollers 7 are connected to a DC motor 8, which drives the rollers 7 to rotate. The web guiding sensor 12 and the web guiding auxiliary sensor 13 are both connected to the control unit and send the detected signals to the control unit.

[0044] The web correction detection unit includes web correction sensors 12 corresponding to web correction components 3 for detecting the state of the rolled fabric 5, and web correction auxiliary sensors 13 disposed at the edge of the web correction platform 1. Preferably, the number of web correction sensors 12 is the same as the number of web correction components 3. For example, when there are three web correction components 3, the number of web correction sensors 12 is also three, and they are respectively disposed on the web correction components 3. On the web correction components 3 located on both sides, the web correction sensors 12 are disposed on the side furthest from the other web correction components 3. Figure 4 As shown, the correction sensor 12 is mounted on the side of the connecting column via a sensor mounting plate. The detection head of the correction sensor 12 faces upward to detect whether there is a roll of cloth 5 on the correction assembly 3. One or two correction auxiliary sensors 13 are included. The correction auxiliary sensors 13 are mounted at the edge of the correction moving platform. Two correction auxiliary sensors are spaced apart at the edge of the correction platform 1 and located on the same side of the edge of the correction platform 1. The correction auxiliary sensors 13 and the correction assembly 3 are arranged in a straight line. If the correction sensor 12 fails during the correction process, there is a risk that the roll of cloth 5 will fall. The correction sensors 12 are all controlled by normally closed signals. If a sensor malfunctions during the correction process and fails to detect the correct position according to the procedure, the system will directly stop and trigger an alarm.

[0045] The alignment correction base 2 includes a base frame 9, a horizontally sliding seat 10 slidably connected to the base frame 9, and a lifting seat 11 slidably connected to the horizontally sliding seat 10. The lifting seat 11 includes a square frame made of profiles, with a lower connecting plate fixed to the bottom of the square frame. The alignment correction platform 1 is axially connected to the lower connecting plate and located above the lifting seat 11. A rotating mechanism for driving the alignment correction platform 1 to rotate is provided inside the lifting seat 11. The horizontally sliding seat 10 can be driven by a cylinder. The rotating mechanism can be a motor-driven structure or a gear and rack structure.

[0046] The control unit, based on the fabric placement information detected by the correction sensor 12 and the fabric edge information detected by the correction auxiliary sensor 13, controls the correction assembly 3 to move the fabric roll 5 to perform edge correction. The correction process includes a reverse laying judgment followed by correction. The correction includes deviations towards the correction auxiliary sensor 13 and deviations away from the correction auxiliary sensor 13, both of which are judged by the correction auxiliary sensor 13. If the correction auxiliary sensor 13 does not detect the fabric edge information, the control unit 3 moves the fabric roll 5 outward, i.e., closer to the correction auxiliary sensor 13, until the correction auxiliary sensor 13 detects the fabric edge, completing the correction. If the fabric edge information is detected, the control unit 3 moves the fabric roll 5 inward, i.e., away from the correction auxiliary sensor 13, a certain distance. If the correction auxiliary sensor 13 does not detect the fabric roll 5, the control unit 3 stops rotating. After a preset time, the fabric roll 5 is moved in the opposite direction until the correction auxiliary sensor 13 detects the fabric edge again, completing the correction.

[0047] Example 2:

[0048] An automatic fabric roll edge alignment and correction method is implemented using an automatic fabric roll edge alignment and correction system. For example... Figure 2 As shown, the method includes the following steps:

[0049] Judgment based on the rotation of the fabric roll;

[0050] The information on the placement of the fabric roll on the correction platform 1 is obtained based on the correction sensor 12;

[0051] After obtaining the information that the roll of fabric has been placed, the edge information of the roll of fabric is obtained according to the correction auxiliary sensor 13;

[0052] Based on the edge information of the rolled fabric, the corresponding correction information is sent to the correction platform 1 until the correction completion signal sent by the correction auxiliary sensor 13 is obtained, and then the completion signal is sent to the correction platform 1.

[0053] The determination of fabric roll rotation specifically includes:

[0054] The system determines whether a fabric roll rotation signal is detected. If a signal is detected, a material picking information is sent to the correction moving base 2, causing the correction moving base 2 to move the correction platform 1 to the picking position to pick up the material. Then, the correction platform 1 is reset and rotated 180°. If no fabric roll rotation signal is detected, the process proceeds to the next step, performing edge correction on fabric roll 5.

[0055] After detecting the fabric roll rotation signal, in actual operation, the origin position information of the fabric spreading machine, the fabric spreading completion information of the fabric spreading machine, and the fabric roll placement information on the correction platform 1 are also detected. When the origin position information of the fabric spreading machine, the fabric spreading completion information of the fabric spreading machine, and the correction sensor 12 and the correction auxiliary sensor 13 all fail to detect the fabric roll 5, a material picking information is sent to the correction moving base 2. The control process of the correction moving base 2 driving the correction platform 1 to the material picking position includes: controlling the correction platform 1 to move forward, after moving forward to the position, the correction platform 1 to rise, and after the correction platform 1 reaches the position to pick up the fabric roll 5 from the fabric spreading machine, then controlling the correction platform 1 to move backward, and after the correction platform 1 reaches the position to descend, and after descending to the position, the material picking is completed.

[0056] The information on the placement of the fabric roll on the correction platform 1 is obtained from the correction sensor 12, specifically including:

[0057] If both the correction sensor 12 and the correction auxiliary sensor 13 detect the roll of fabric 5, it is determined that the roll of fabric 5 is placed on the correction platform 1. The edge information of the roll of fabric is detected by the correction auxiliary sensor 13 to perform edge correction. If neither the correction sensor 12 nor the correction auxiliary sensor 13 detects the roll of fabric 5 during the detection of the roll of fabric placement information and the roll of fabric edge information, the correction stops, an alarm is triggered, and the machine is shut down, awaiting manual intervention.

[0058] Based on the fabric roll edge information, corresponding correction information is sent to the correction platform 1 until the correction completion signal sent by the correction auxiliary sensor 13 is obtained, and then the completion signal is sent to the correction platform 1, specifically including:

[0059] When a correction auxiliary sensor 13 is set at the edge of the correction platform 1, the detection by the correction auxiliary sensor 13 includes two cases, specifically:

[0060] In the first case, if the unidentified information of the edge of the roll is obtained, a first correction signal is sent to the correction platform 1 to cause the correction component 3 to move the roll 5 in the first direction until the identification information of the edge of the roll is obtained, and a completion signal is sent to the correction platform 1.

[0061] In the second case, if the edge recognition information of the rolled cloth is obtained, a second correction signal is sent to the correction component 3 to cause the correction component 3 to move the rolled cloth 5 in the second direction until the edge recognition information of the rolled cloth is obtained. Then, a return signal is sent to the correction platform 1 to cause the correction component 3 to move the rolled cloth 5 in the first direction until the edge recognition information of the rolled cloth is obtained. Finally, a completion signal is sent to the correction platform 1.

[0062] The first direction is opposite to the second direction. The roll of cloth 5 moves laterally under the drive of the correction component 3, wherein the first direction movement is the roll of cloth 5 moving towards one side of the correction platform 1, and the second direction movement is the roll of cloth 5 moving towards the other side of the correction platform 1.

[0063] To illustrate with a practical example, in the first scenario, if the correction assist sensor 13 does not detect the fabric roll 5, the system detects the position of the correction platform 1. If the correction platform 1 is in the forward rotation position, the system controls the correction component 3 to rotate forward, causing the fabric roll 5 to move in the first direction until the correction assist sensor 13 detects the fabric roll 5 and obtains the edge detection information, at which point the correction component 3 stops rotating. If the correction platform 1 is in the reverse rotation position, the system controls the correction component 3 to switch between forward and reverse rotation, causing the correction component 3 to reverse. The forward rotation position, reverse rotation position, forward rotation, reverse rotation, and first direction are predefined. For example, if clockwise rotation of the correction platform 1 is predefined as forward rotation, and the position where the correction platform 1 can rotate forward is the forward rotation position, then counterclockwise rotation is the reverse rotation, and the position where the correction platform 1 can reverse is the reverse rotation position. Similarly, if the first direction is defined as the fabric roll 5 moving to the left, then the second direction is moving to the right.

[0064] In the second scenario, the correction assist sensor 13 detects the rolled fabric 5. Similarly, the system detects the position of the correction platform 1. If the correction platform 1 is in the forward rotation position, the correction component 3 is controlled to rotate in reverse, moving the rolled fabric 5 in the second direction until the correction assist sensor 13 no longer detects the rolled fabric 5, returns a signal, and the correction component 3 stops rotating. After a preset time, the correction component 3 is controlled to rotate forward, moving the rolled fabric 5 in the first direction until the correction assist sensor 13 detects the rolled fabric 5, obtains the edge detection information, and the correction component 3 stops rotating. If the correction platform 1 is in the reverse rotation position, the forward and reverse rotation control of the correction component 3 is interchanged. The preset time can be set to 1 second.

[0065] After the correction is completed, the fabric spreading machine is loaded. The loading program is started when the fabric spreading machine is detected to be in the correct position and a signal indicating that the fabric spreading is complete is received. The correction platform 1 is raised by the correction moving base 2. After it rises to the correct position, it moves towards the fabric spreading machine. After it moves to the correct position, the correction platform 1 is lowered to complete the loading. After the correction platform 1 is lowered to the correct position, it moves backward until it is in the correct position, and the loading process ends.

[0066] Example 3:

[0067] An automatic fabric roll edge alignment and correction method is implemented using an automatic fabric roll edge alignment and correction system. For example... Figure 2 As shown, the method includes the following steps:

[0068] Judgment based on the rotation of the fabric roll;

[0069] The information on the placement of the fabric roll on the correction platform 1 is obtained based on the correction sensor 12;

[0070] After obtaining the information that the roll of fabric has been placed, the edge information of the roll of fabric is obtained according to the correction auxiliary sensor 13;

[0071] Based on the edge information of the rolled fabric, the corresponding correction information is sent to the correction platform 1 until the correction completion signal sent by the correction auxiliary sensor 13 is obtained, and then the completion signal is sent to the correction platform 1.

[0072] The determination of fabric roll rotation specifically includes:

[0073] The system determines whether a fabric roll rotation signal is detected. If a signal is detected, it sends material picking information to the correction moving base 2, causing the correction moving base 2 to move the correction platform 1 to the picking position to pick up the material. Then, it moves the correction platform 1 back to its original position and rotates 180°. If no fabric roll rotation signal is detected, the system proceeds to the next step to perform fabric roll edge correction.

[0074] After detecting the fabric roll rotation signal, in actual operation, the origin position information of the fabric spreading machine, the fabric spreading completion information of the fabric spreading machine, and the fabric roll placement information on the correction platform 1 are also detected. When the origin position information of the fabric spreading machine, the fabric spreading completion information of the fabric spreading machine, and the correction sensor 12 and the correction auxiliary sensor 13 all fail to detect the fabric roll 5, a material picking information is sent to the correction moving base 2. The control process of the correction moving base 2 driving the correction platform 1 to the material picking position includes: controlling the correction platform 1 to move forward, after moving forward to the position, the correction platform 1 to rise, and after the correction platform 1 reaches the position to pick up the fabric roll 5 from the fabric spreading machine, then controlling the correction platform 1 to move backward, and after the correction platform 1 reaches the position to descend, and after descending to the position, the material picking is completed.

[0075] The information on the placement of the fabric roll on the correction platform 1 is obtained from the correction sensor 12, specifically including:

[0076] If both the correction sensor 12 and the correction auxiliary sensor 13 detect the roll of fabric 5, it is determined that the roll of fabric 5 is placed on the correction platform 1. The edge information of the roll of fabric is detected by the correction auxiliary sensor 13 to perform edge correction. If neither the correction sensor 12 nor the correction auxiliary sensor 13 detects the roll of fabric 5 during the detection of the roll of fabric placement information and the roll of fabric edge information, the correction stops, an alarm is triggered, and the machine is shut down, awaiting manual intervention.

[0077] Based on the fabric roll edge information, corresponding correction information is sent to the correction platform 1 until the correction completion signal sent by the correction auxiliary sensor 13 is obtained, and then the completion signal is sent to the correction platform 1, specifically including:

[0078] In this embodiment, two correction auxiliary sensors 13 are used, which are respectively and spaced apart on the edge of the correction platform 1. The correction auxiliary sensors 13 detect two cases, specifically,

[0079] In the first case, if one roll edge recognition information and one roll edge unrecognized information are obtained, a completion signal is sent to the correction platform 1.

[0080] In the second case, if two unidentified information of the edge of the roll of cloth is obtained, the first correction signal is sent to the correction platform 1 to cause the correction component 3 to move the roll of cloth 5 in the first direction until one roll of cloth edge identification information is obtained, and a completion signal is sent to the correction platform 1.

[0081] In the third case, if two roll edge recognition information are obtained, a second correction signal is sent to the correction component 3 to cause the correction component 3 to move the roll 5 in the second direction until an unrecognized roll edge information is obtained, and a completion signal is sent to the correction platform 1.

[0082] The first direction is opposite to the second direction.

[0083] To illustrate with a practical example, in the first case, if one correction auxiliary sensor 13 detects the roll of fabric 5 while the other correction auxiliary sensor 13 does not detect the roll of fabric 5, then a completion signal is sent to the correction platform 1.

[0084] In the second scenario, if neither of the two correction auxiliary sensors 13 detects the fabric roll 5, the system detects the position of the correction platform 1. If the correction platform 1 is in the forward rotation position, the system controls the correction component 3 to rotate forward, causing the fabric roll 5 to move in the first direction until the correction auxiliary sensor 13 detects the fabric roll 5 and obtains fabric roll edge detection information, at which point the correction component 3 stops rotating. If the correction platform 1 is in the reverse rotation position, the system controls the correction component 3 to switch between forward and reverse rotation, causing the correction component 3 to rotate in reverse.

[0085] In the third scenario, both correction auxiliary sensors 13 detect the fabric roll 5. The system detects the position of the correction platform 1. If the correction platform 1 is in the forward rotation position, the system controls the correction component 3 to reverse, causing the fabric roll 5 to move in the second direction until the correction auxiliary sensors 13 no longer detect the fabric roll 5, acquiring information that the edge of the fabric roll is not identified, and the correction component 3 stops rotating. If the correction platform 1 is in the reverse rotation position, the system controls the correction component 3 to switch between forward and reverse rotation.

[0086] After the correction is completed, the fabric spreading machine is loaded. The loading program is started when the fabric spreading machine is detected to be in the correct position and a signal indicating that the fabric spreading is complete is received. The correction platform 1 is raised by the correction moving base 2. After it rises to the correct position, it moves towards the fabric spreading machine. After it moves to the correct position, the correction platform 1 is lowered to complete the loading. After the correction platform 1 is lowered to the correct position, it moves backward until it is in the correct position, and the loading process ends.
