Description
Technical Field
The present invention relates to a motor control system for a roll-to-roll apparatus, and more particularly, to a motor control system for a roll-to-roll apparatus.
Background
It is known that after a textile fabric (e.g., piece goods) is produced, it must be inspected for defects before it is shipped to a package. Currently, inspection of defects in cloth is usually performed by an operator through operation of a cloth inspecting machine. From the disclosure of taiwan patent No. 217040, the main structure of the conventional cloth inspecting machine includes: a material feeding mechanism, a material spreading mechanism and a material receiving mechanism. Typically, the cloth unwinding mechanism has a first transmission drum, a cloth inspecting platform and a second transmission drum, wherein the first transmission drum is located between the discharging mechanism and the cloth inspecting platform and adjacent to the top side of the cloth inspecting platform. On the other hand, the second transmission cylinder is positioned between the material receiving mechanism and the cloth inspecting platform and is adjacent to the bottom side of the cloth inspecting platform.
When the cloth is checked, an operator stands in front of an operation platform and controls the cloth releasing speed of the discharging mechanism, the rotating speeds of the first transmission cylinder and the second transmission cylinder and the cloth winding speed of the material receiving mechanism in a mode of operating a controller. Then, in the process of controlling the cloth transmission (movement), the operator checks the cloth block spread on the cloth inspecting platform by human eyes. If the operator finds that the piece of cloth under inspection contains a flaw, the operator operates
The controller is operated to stop the delivery of the piece of cloth, then determine whether the defect is repairable, and mark the defect if the defect is repairable or not. And finally, receiving the cloth subjected to flaw detection by the discharging mechanism.
The operator's experience feedback indicates that the known cloth inspecting machines have the following drawbacks in practical use:
(1) The operator checks with his eyes during the cloth drive (movement) whether there are defects in the piece of cloth spread out on the cloth inspection platform, in such a way that there are inevitably missed defects in the piece of cloth.
(2) In the case of a defect found in the cloth, the operator stops the cloth feed and starts the cloth feed again after the defect is repaired or marked at the position of the defect. In the process of conveying, stopping and conveying the cloth, if an operator does not accurately master the feeding speed of the feeding mechanism, the rotating speeds of the first transmission cylinder and the second transmission cylinder and the receiving speed of the receiving mechanism, the cloth is rolled into a barrel shape, and the side surfaces of the two ends of the cloth cannot be a cut and aligned section.
It should be understood that the discharging mechanism and the receiving mechanism of the cloth inspecting machine are a set of roll-to-roll mechanisms, and the cloth unwinding mechanism is a processing mechanism (for detecting defects on the cloth) between the discharging mechanism and the receiving mechanism. Currently, many articles are manufactured using roll-to-roll mechanisms, such as: metal foil, metal sheet, flexible touch panel, flexible circuit board, flexible solar cell, and the like. Therefore, there is a need for structural and functional improvements to the prior art roll-to-roll apparatus. In view of the above, the present inventors have made extensive studies and as a result, have developed a motor control system for an apparatus having a roll-to-roll mechanism.

Please refer to fig. 1 and fig. 2, which respectively show a first perspective view and a second perspective view of an apparatus having a roll-to-roll mechanism to which a motor control system of the present invention is applied. As shown in fig. 1 and 2, the apparatus 2 with roll-to-roll mechanism is a cloth inspecting machine, and mainly comprises: a frame 20, a discharge mechanism 21, a processing mechanism 22, a receiving mechanism 23, and an operator platform 24. It should be noted that the cloth inspecting machine shown in fig. 1 and 2 is used to assist the application form of the motor control system 1 of the present invention, and is not used to limit the application of the motor control system 1 of the present invention. In a possible embodiment, the motor control system 1 of the invention can be applied in any kind of apparatus 2 having a roll-to-roll mechanism. It should be noted that, in the case where the apparatus 2 with a reel-to-reel mechanism is a cloth inspecting machine, the processing mechanism 22 is a cloth inspecting mechanism and includes: a first driving cylinder 221, a processing platform 222 and a second driving cylinder 223.
With continuing reference to fig. 1 and 2 and with further reference to fig. 3, a first block diagram of a motor control system of the present invention is shown. In addition, please refer to fig. 4, which shows the material placing machine
A first side view of the mechanism 21, the handling mechanism 22, the receiving mechanism 23, and the operator platform 24. To illustrate further, the apparatus 2 with roll-to-roll mechanism further comprises a plurality of motors, respectively: a first motor 210 for driving the discharging mechanism 21 to discharge the continuous material 3, at least a second motor 220 for driving the first driving cylinder 221 and the second driving cylinder 222 to spread the continuous material on the processing platform 222, and a third motor 230 for driving the receiving mechanism 23 to receive the continuous material. In the case where the apparatus 2 with roll-to-roll mechanism is a cloth inspecting machine, the continuous material 3 is a piece of cloth. It should be understood that the discharging mechanism 21 and the receiving mechanism 23 of the cloth inspecting machine are a set of roll-to-roll mechanisms, and the processing mechanism 22 is a processing mechanism (for performing defect detection processing on the cloth) between the discharging mechanism and the receiving mechanism. Currently, many articles are manufactured using roll-to-roll mechanisms, such as: metal foil, metal sheet, flexible touch panel, flexible circuit board, flexible solar cell, and the like. In other words, in the case that the motor control system 1 of the present invention is applied to different devices 2 having roll-to-roll mechanisms, the continuous material 3 may be a metal foil, a flexible touch panel, a flexible circuit board, a flexible solar cell, or the like.
With continuing reference to fig. 1, 2 and 3, and with further reference to fig. 4, a first side view of the drop off mechanism 21, the processing mechanism 22, the material receiving mechanism 23, and the operator platform 24 is shown. According to the design of the invention, the motor control system comprises: a line light source 11, N first cameras 12, a processing module 13, and a supporting mechanism 14. Wherein the supporting mechanism 14 is disposed at a first imaging position between the discharging mechanism 21 and the processing mechanism 22. Also, the linear light source 11 is disposed at a first position so as to face the first image pickup position. On the other hand, N first cameras 12 are disposed at a second position facing the first imaging position, and N is a positive integer of at least 1.
More specifically, the processing module 13 is coupled to the line light source 11 and the first camera 12, and includes: a feature processing unit 131, a defect identification unit 132, a motor control unit 133, a human-machine interface unit 134, and a continuous web motion monitoring unit 135. In one embodiment, the processing module 13 is integrated into a machine control of the apparatus 2 with roll-to-roll mechanism. It should be noted that, in a possible embodiment, the processing module 13 may also be integrated in an electronic device, and the electronic device information is connected to a machine control device of the apparatus 2 with roll-to-roll mechanism.
With continuing reference to fig. 1, fig. 2, fig. 3, and fig. 4, and with simultaneous reference to fig. 5, perspective views of the line light source 11, the N first cameras 12, the processing module 13, and the supporting mechanism 14 are shown. According to the design of the present invention, during the process that the feeding mechanism 21 feeds a continuous material 3 to the processing mechanism 22 at a feeding speed, the processing module 13 controls the linear light source 11 to continuously provide a detection light to the first camera position, and simultaneously controls the first camera 12 to take pictures of the continuous material passing through the first camera position at an image acquisition frequency, so as to obtain multiple frames of first continuous material images in a time-continuous manner. In one embodiment, the image acquisition frequency is positively correlated to the discharge speed. It should be noted that, as shown in fig. 4 and 5, the supporting mechanism 14 is disposed at the first image capturing position for supporting the continuous material 3, so that the continuous material 3 is flattened through a captured portion (photographic portion) 31 of the first image capturing position.
It should be noted that each of the first cameras 12 has a shooting range, and N of the first cameras 12 have a total shooting range, and a width of the total shooting range is greater than or equal to a width of the continuous material.
According to the design of the present invention, the feature processing unit 131 performs a feature extraction process on each of the first continuous material images to obtain a first continuous material feature image. Therefore, after the feature extraction processing is performed on a plurality of temporally continuous first continuous material images, a plurality of first continuous material feature images are generated. Then, the defect identification unit 132 performs a feature matching procedure on each of the first continuous material feature images and a continuous material feature template, so as to determine whether the first continuous material image contains at least one defect. Moreover, if it is determined that the first continuous material image contains at least one defect, the motor control unit 133 controls a first motor 210 of the discharging mechanism 21, at least a second motor 220 of the processing mechanism 22, and a third motor 230 of the receiving mechanism 23 to stop operating, so that the defective portion of the continuous material is located on a processing platform 222 of the processing mechanism.
As shown in fig. 3, the motor control system 1 of the present invention further includes a first rotation speed sensor S1, a second rotation speed sensor S2 and a third rotation speed sensor S3. The first rotation speed sensor S1 is connected to the first motor 210 to detect a first rotation speed of the first motor 210, the second rotation speed sensor S2 is connected to the second motor 220 to detect a second rotation speed of the second motor 220, and the third rotation speed sensor S3 is connected to the third motor 230 to detect a third rotation speed of the third motor 230. Thus, the processing module 13 can calculate a first moving distance of the continuous material between the discharging mechanism 21 and the processing mechanism 22 by the continuous material movement monitoring unit 135 according to the first rotating speed and the first rotating speed. Thus, in the case that it is determined that the first continuous material image includes at least one defect, the motor control unit 133 controls a first motor 210 of the discharge mechanism 21, at least a second motor 220 of the processing mechanism 22, and a third motor of the receiving mechanism 23
Up to 230, so that the defective portion of the web is located on a processing platform 222 of the processing mechanism.
Of course, the processing module 13 may also have the continuous material moving monitoring unit 135 to calculate a second moving distance of the continuous material between the processing mechanism 22 and the receiving mechanism 23 according to the second rotating speed and the third rotating speed.
When a defect is identified for a web positioned on the processing platform 222, the operator may repair the defect directly. However, if the defect is not repairable, the operator marks the defect location. After completing the above actions, the operator can send a re-operation command to the processing module 13 by operating the human-machine interface unit 134 of the processing module 13. After receiving the run-back command, the processing module 13 controls the first motor 210, the second motor 220 and the third motor 230 to run back by the motor control unit 133. During the resuming operation, the first motor 210 rotates at the original first rotation speed, the second motor 220 rotates at the original second rotation speed, and the third motor 230 rotates at the original third rotation speed.
Second embodiment
Please refer to fig. 6, which shows a second side view of the discharging mechanism 21, the processing mechanism 22, the receiving mechanism 23 and the operator platform 24 to which the present invention is applied. Referring to fig. 7, a second block diagram of the motor control system of the present invention is shown. In the second embodiment, the motor control system 1 of the present invention further includes: a second camera 15 and a light source 16. As shown in fig. 6 and 7, the second camera 15 is coupled to the processing module 13 and disposed at a third position facing a second imaging position between the processing mechanism 22 and the receiving mechanism 23. In other words, the material is received by the receiving mechanism 23
During the process of (rewinding) the continuous material 3, the processing module 13 controls the second camera 15 to photograph the continuous material 3 passing through the second photographing position, so as to obtain at least one frame of a second continuous material image. It should be noted that the light source 16 is used to provide the required illumination when the second camera 15 is taking images.
Fig. 7 shows that the processing module 13 further includes a tension degree evaluation unit 136 for monitoring a tension degree of the continuous material 3 in real time during the material receiving of the continuous material 3 by the material receiving mechanism 23. More specifically, during the process of receiving the continuous material 3 by the receiving mechanism 23, the processing module 13 controls the second camera 15 to photograph the continuous material 3 passing through the second photographing position, so as to obtain at least one frame of a second continuous material image. Then, the processing module 13 performs a feature extraction process on the second continuous material image by using the feature processing unit 131 to obtain a second continuous material feature image. Continuously, the processing module 13 uses the tension degree evaluating unit 136 to perform a tension evaluating operation according to the second continuous material feature image, so as to obtain a tension degree of the continuous material 3 during material receiving. Finally, in the case that the tension level exceeds an upper threshold or a lower threshold, the processing module 13 controls a tension adjusting mechanism 231 of the receiving mechanism 23 to adjust the tension level.
Thus, the foregoing is a complete and clear description of a motor control system for an apparatus having a roll-to-roll mechanism in accordance with the present invention; moreover, the present invention has the following advantages as follows:
(1) In the case of the motor control system 1 according to the invention, a continuous block of material, containing at least one defect, of the continuous material 3 is automatically moved to the processing station 222 and stops on the processing station 222 for confirmation or at least one processing by the operator, who has no defects
The continuous material 3 is manually stopped. For example, in the case of the continuous material 3 being a piece of cloth, after the operator performs the repairing or marking operation on the defect on the continuous material block, the operator can operate the human-machine interface unit 134 of the processing module 13 to make the processing module 13 control the first motor 210, the second motor 220 and the third motor 230 to operate again. During the second operation, the first motor 210 rotates at the original first speed, the second motor 220 rotates at the original second speed, and the third motor 230 rotates at the original third speed. In the whole process, an operator does not need to manually adjust the rotating speed of any motor.
(2) In the case of applying the motor control system 1 of the present invention, the initial conveying speed of the continuous material 3 and the conveying speed after restarting the conveying are fixed, so that the continuous material wound into a cylindrical shape by the material receiving mechanism 23 has a cut-off section at both side surfaces. In the whole process, an operator does not need to manually regulate the discharging speed of the discharging mechanism 21, the rotating speeds of the first transmission cylinder 221 and the second transmission cylinder 223 and the receiving speed of the receiving mechanism 23.
Thus, the foregoing is a complete and clear description of a motor control system for an apparatus having a roll-to-roll mechanism in accordance with the present invention. It should be emphasized that the above detailed description is specific to possible embodiments of the invention, but this is not intended to limit the scope of the invention, and equivalents and modifications, which do not depart from the technical spirit of the invention, are intended to be included within the scope of the invention.
