Abstract
Description
Technical Field
[0001] This application relates to the field of winding devices, and more specifically to winding devices. Background Technology
[0002] Continuous fiber reinforced thermoplastic prepreg tape is a composite material that uses continuous fibers as reinforcement and thermoplastic resin as the matrix. During the production process, this tape exhibits high fiber orientation, resulting in extremely high tensile strength in the fiber orientation direction. Furthermore, the tape has good fiber-resin bonding, high toughness, and is difficult to fracture laterally.
[0003] Currently, this type of strip is mainly wound using a torque winding machine. During the winding process, the worker attaches the starting edge of the strip to the core, and then the torque winding machine drives the core to rotate, thereby winding the strip onto the core.
[0004] When attaching the strip to the core, the worker must ensure that the starting edge of the strip adheres well to the outer circumference of the core to avoid wrinkles or bulges. Wrinkles or bulges can damage the strip during subsequent winding.
[0005] Furthermore, the increasing speed of strip production has also increased the difficulty of strip winding operations. During the winding process, if a worker's hand gets caught in the wound strip, the strip's high strength could cause injury, resulting in a safety accident.
[0006] Therefore, this application provides a winding device to at least partially solve the above-mentioned problems. Summary of the Invention
[0007] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed embodiments section. This summary section is not intended to limit the key features and essential technical features of the claimed technical solutions, nor is it intended to determine the scope of protection of the claimed technical solutions.

[0010] A take-up shaft, rotatably connected to the frame, for winding the strip;
[0011] The sensor is used to emit sensing light to sense a sensing signal indicating that the object under test has entered the winding area. The winding area is located between the sensor and the strip in the circumferential direction around the axis of the take-up shaft and in the winding direction of the strip along the take-up shaft. The winding area is located upstream of the strip.
[0012] The controller is electrically connected to the sensor and the take-up shaft. The controller controls the take-up shaft to stop rotating based on the sensing signal.
[0013] Specifically, the winding center angle of the winding area relative to the center of the winding shaft is determined based on the parameters of the winding outer diameter, winding speed, and human reaction time, thereby determining the winding area and thus the position of the sensor.
[0014] According to the winding device of this application, the sensor can sense a sensing signal indicating that the object under test has entered the winding area. When the object under test enters the winding area, the controller controls the winding shaft to stop rotating according to the sensing signal to avoid damage to the object under test and to avoid safety accidents. In addition, the winding center angle of the winding area relative to the center of the winding shaft is determined according to the winding outer diameter, winding speed and human reaction time parameters, thereby determining the winding area and the position of the sensor, which can more effectively avoid damage to the object under test.

Along a second horizontal direction perpendicular to the first horizontal direction, the protective beam is located on the side of the take-up shaft away from the sensor. Along the second horizontal direction, the maximum distance between the protective beam and the take-up shaft is a preset safety distance.
[0025] Optionally, the winding device further includes a conveyor roller parallel to the winding shaft in the axial direction. In the second horizontal direction, the conveyor roller is located on the side of the winding shaft away from the guard beam.

However, it will be apparent to those skilled in the art that embodiments of this application may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with embodiments of this application.
[0045] The preferred embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.
[0046] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order.
[0047] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may be available in addition to these detailed descriptions.
[0048] This application provides a winding device. The winding device can be used to wind a strip 140 around a core 130. The strip 140 can be a continuous fiber-reinforced thermoplastic prepreg strip. During the winding of the strip 140, when a worker 190 is about to be encircled by the strip 140, the winding of the strip 140 can be stopped in time, thereby reducing the possibility of injury to the worker 190.
[0049] Please refer to Figures 1 to 4 The winding device includes a frame 110, a winding shaft 120, and a winding drive assembly (not shown). The frame 110 is fixedly mounted on the ground.
[0050] The take-up shaft 120 can be an air-expanding shaft. The take-up shaft 120 is rotatably connected to the frame 110 about its axis. The axial direction of the take-up shaft 120 is parallel to a first horizontal direction D1. The take-up drive assembly includes a motor and a reduction gear. The input shaft of the reduction gear is connected to the output shaft of the motor. The output shaft of the reduction gear is connected to the take-up shaft 120. Thus, the motor drives the take-up shaft 120 to rotate via the reduction gear.
[0051] The core 130 has a cylindrical structure. A take-up shaft 120 can be inserted through the core 130. The core 130 is connected to the take-up shaft 120. In this way, the take-up shaft 120 can drive the core 130 to rotate around the axis of the take-up shaft 120, so that the core 130 can be wound around the strip 140.
[0052] Please continue to refer to this. Figures 1 to 4 The winding device also includes a sensor 150 and a controller (not shown). The sensor 150 is used to emit sensing light 153. The sensor 150 can sense a sensing signal indicating that the object under test has entered the winding area 160 by sensing light 153.
[0053] Among them, such as Figure 2 As shown, in the circumferential direction around the axis of the take-up shaft 120, the winding area 160 is located between the sensor 150 and the strip 140. Along the winding direction B of the take-up shaft 120 winding the strip 140, the winding area 160 is located upstream of the strip 140. The winding area 160 is located outside the strip roll 196 described later. When a foreign object (the object to be measured) enters the winding area 160, the wound strip 140 may damage the foreign object, or the foreign object may damage the strip 140.
[0054] The controller is electrically connected to the sensor 150 and the take-up drive assembly (that is, electrically connected to the take-up shaft 120 via the take-up drive assembly). The controller can control the operation of the take-up drive assembly, thereby controlling the rotation of the take-up shaft 120.
[0055] When the controller receives a sensing signal through sensor 150, it indicates that the object under test has entered the winding area 160. At this time, the controller controls the take-up shaft 120 to stop rotating according to the sensing signal, thereby stopping the winding of the strip 140.
[0056] The object to be tested can be the hand of worker 190. When worker 190 violates the rules by allowing their hand to enter the winding area 160, sensor 150 detects a signal. At this time, the controller controls the take-up shaft 120 to stop rotating, thereby preventing worker 190 from being injured.
[0057] At times, when the strip 140 is wound around the core 130, wrinkles and protrusions appear on the strip 140. At this time, the object to be measured is the wrinkles and protrusions of the strip 140. Thus, when the wrinkles and protrusions of the strip 140 rotate into the winding area 160, the sensor 150 detects a sensing signal. At this point, the controller controls the take-up shaft 120 to stop rotating, thereby preventing damage to the strip 140.
[0058] The winding center angle α of the winding area 160 relative to the center of the winding shaft 120 can be determined based on the winding outer diameter φ, the winding speed V, and the human reaction time parameter A, thereby determining the winding area and thus the position of the sensor.
[0059] The outer diameter φ of the winding is the outer diameter of the roll 196 formed by the strip 140 winding around the core 130. The winding speed is the translational speed of the strip 140. The human reaction time parameter A can be determined experimentally. α is the central angle α of the arc 161 that forms the winding area 160 of the roll 196. It should be noted that the roll 196 includes the core 130 and the strip 140 wound around the core 130. When the core 130 has not yet wound the strip 140, the roll 196 is the core 130.
[0060] In this way, the winding center angle α can be accurately determined, and the winding area 160 can be determined by the winding center angle α, thereby determining the position of the sensor 150. That is, for a single production batch of winding operations, the current position of the sensor 150 can be determined based on the current winding outer diameter φ, winding speed V, and human reaction time parameter A, and then the position of the sensor 150 on the frame 110 can be adjusted. For different batches of winding operations, if at least one of the winding outer diameter φ, winding speed V, and human reaction time parameter A is different, the position of the sensor 150 on the frame 110 will also be different. Therefore, the position of the sensor 150 can be adjusted accordingly for different winding outer diameter φ, winding speed V, and human reaction time parameter A, thereby more effectively avoiding damage to the object being measured.
[0061] In this embodiment, the sensor 150 can sense a sensing signal indicating that the object under test has entered the winding area 160. When the object under test enters the winding area 160, the controller controls the take-up shaft 120 to stop rotating according to the sensing signal to avoid damage to the object under test and to avoid safety accidents. In addition, the winding center angle α of the winding area 160 relative to the center of the take-up shaft 120 is determined according to the winding outer diameter φ, the winding speed V and the human reaction time parameter A, thereby determining the winding area and the position of the sensor, which can more effectively avoid damage to the object under test.
[0062] Preferably, α = (360° * AV) / (φπ).
[0063] Where π is the mathematical constant pi. ≈π3.1415926935.
[0064] Therefore, the central angle α can be determined more accurately.
[0065] Furthermore, the central angle α of the winding region 160 relative to the center of the take-up shaft 120 is in the range of 100°≤α≤140°. This allows for more effective prevention of damage to the object under test.
[0066] like Figure 3As shown. Sensor 150 includes an infrared emitter 151 and an infrared receiver 152. Along the radial direction of the take-up spool 120, sensor 150 is located to the side of the take-up spool 120. Along the axial direction of the take-up spool 120, infrared emitter 151 is located on one side of the strip 140, and infrared receiver 152 is located on the other side of the strip 140. Sensing light 153 is infrared light emitted by infrared emitter 151 to infrared receiver 152. Sensing light 153 is parallel to the axial direction of the take-up spool 120.
[0067] As the object under test enters the entrainment area 160, it blocks the sensing light 153, preventing the infrared receiver 152 from receiving it. At this time, the sensor 150 generates a sensing signal. This allows for more accurate sensing of the signal.
[0068] Please continue to refer to this. Figure 3 The infrared emitter 151 includes a lens 154 for emitting infrared light. The axis of the lens 154 is parallel to the axial direction of the take-up spool 120. The minimum dimension w between the axis of the lens 154 and the outer peripheral surface of the take-up spool 120 is in the range of 1 mm ≤ w ≤ 2 mm. Thus, the sensing light 153 emitted by the infrared emitter 151 through the lens 154 is parallel to the axial direction of the take-up spool 120. The dimension w between the sensing light 153 and the outer peripheral surface of the take-up spool 120 allows for more accurate sensing of the sensing signal.
[0069] Please return Figure 1 and Figure 4 The winding device also includes a protective beam 170. The protective beam 170 is connected to the frame 110. The length direction of the protective beam 170 is parallel to the axial direction of the winding shaft 120, and along a second horizontal direction D2 perpendicular to the first horizontal direction D1. The protective beam 170 is located on the side of the winding shaft 120 away from the sensor 150. Along the second horizontal direction D2, the maximum distance between the protective beam 170 and the winding shaft 120 is a preset safety distance. The preset safety distance can be set as needed. Thus, along the second horizontal direction D2, the worker 190 can stand on the side of the protective beam 170 away from the winding shaft 120 to work, reducing the possibility of the worker 190's hands entering the winding area 160.
[0070] Please continue to refer to this. Figure 1 and Figure 4The winding device also includes a conveyor roller 180. The conveyor roller 180 is rotatably connected to the frame 110 about its axis. The axial direction of the conveyor roller 180 is parallel to the axial direction of the winding shaft 120. Along the second horizontal direction D2, the conveyor roller 180 is located on the side of the winding shaft 120 away from the guard beam 170. Along the vertical direction D3, there is a gap between the conveyor roller 180 and the winding shaft 120. In this way, the strip 140 adheres to the outer circumferential surface of the conveyor roller 180. After passing over the conveyor roller 180, the strip 140 extends to the winding shaft 120 to connect to the core 130. Thus, the orientation of the strip 140 can be changed by the conveyor roller 180. Therefore, the winding device has a simple structure.
[0071] Furthermore, along the vertical direction D3, the conveyor roller 180 is positioned above the take-up shaft 120. This allows the take-up shaft 120 to be positioned at a lower height, facilitating operation by the worker 190.
[0072] Preferably, such as Figure 1 and Figure 4 As shown, the winding device also includes a start button 191 electrically connected to the controller. The operator 190 can press the start button 191 to send a start signal to the controller. When the controller receives the start signal, it controls the winding drive assembly to start operating. The controller also controls the sensor 150 to start operating when it receives the start signal.
[0073] The winding device also includes a stop button 192 electrically connected to the controller. The operator 190 can press the stop button 192 to send a stop signal to the controller. Upon receiving the stop signal, the controller stops the winding drive assembly.
[0074] The winding device also includes a jog button 193 electrically connected to the controller. The operator 190 can press the jog button 193 to send a jog signal to the controller. When the controller receives a jog signal, it controls the winding drive assembly to operate for a preset duration. The preset duration can be set as needed.
[0075] The winding device also includes a meter counter (not shown). The meter counter is electrically connected to the controller. The meter counter is used to press against the strip 140 to count the number of meters of strip 140 wound by the winding shaft 120.
[0076] The winding device also includes a reset button 194 electrically connected to the controller. The operator 190 can press the reset button 194 to send a reset signal to the controller. Upon receiving the reset signal, the controller controls the winding drive assembly to rotate the winding shaft 120 to a preset angle position (reset). Upon receiving the reset signal, the controller also stops the sensor 150 from operating. Finally, the controller records the current reading of the meter counter.
[0077] The winding device also includes an emergency stop button 195 electrically connected to the controller. The operator 190 can press the emergency stop button 195 to send an emergency stop signal to the controller. Upon receiving the emergency stop signal, the controller stops the winding drive assembly.
[0078] The working steps of the winding device include step one and step two.
[0079] Step 1: The operator 190 first clicks the start button 191 to make the take-up shaft 120 containing the core 130 start rotating, and the sensor 150 starts working.
[0080] Step 2: The worker 190 stands outside the protective beam 170, pulls the starting edge of the strip 140 (the part of the strip 140 that starts to wind into the core 130) with both hands, and aligns the starting edge with the outer circumference of the core 130. In this way, the rotating core 130 can take the strip 140 into the core 130, and then wind it up through the take-up shaft 120.
[0081] In step two, during the winding process, if the operator 190's movements are not standardized and their hand passes through the infrared beam and enters the winding area 160, the hand will block the infrared beam, preventing the sensor 150 from detecting the signal. At this time, the controller will stop the winding drive assembly and the sensor 150. After the operator 190 removes their hand, the process returns to step one.
[0082] In step two, during the winding process, the operator 190's movements were not standardized, causing the starting edge of the strip 140 to not properly adhere to the outer circumference of the core 130, resulting in wrinkles and protrusions on the strip 140 wound onto the core 130. As the winding shaft 120 rotates past the infrared beam and enters the winding area 160, the wrinkles and protrusions block the infrared light, preventing the sensor 150 from detecting the signal. At this point, the controller stops the winding drive assembly and the sensor 150. After the operator 190 removes the aforementioned wrinkles and protrusions, the process returns to step one.
