[0047] Reference Figure 1 , 2 , Figure 1 The structural diagram of the cable winding device provided by some embodiments of the present application is shown in the figure, Figure 2 The cross-sectional view of the cable winding device provided by some embodiments of the present application is shown in the figure. In some embodiments of the present application, the present application provides a cable winding device, which comprises a winding drum 1 and a cutting device 8. The winding drum 1 is used to accommodate the cable, and the cable is fixed on the winding drum 1 by winding. When the cable accommodated in the winding drum 1 reaches a predetermined value, the winding drum 1 is a full winding drum 1 at this time. Then the cutting device 8 can cut the cable, so as to separate the cable accommodated in the winding drum 1 from the cable not accommodated, and then accommodate the cable not accommodated in the winding drum 1 of the next station. It can be understood that the above-mentioned winding drum 1 of the next station is an empty winding drum 1 used to replace the full winding drum 1, and the cable not accommodated after cutting is wound on the empty winding drum 1.

[0048] The cable passes through the cutting device 8 and is wound on the winding drum 1. The cable winding device further comprises a support mechanism 4, which is composed of two support frames 6 and a base 5. The support frames 6 are vertically installed on the base 5, and the winding drum 1 is erected between the two support frames 6. The cutting device 8 is installed on the base 5, so that the distance between the cutting device 8 and the winding drum 1 is small. After the cable is cut off, the length of the cable between the cutting device 8 and the winding drum 1 is short, which can quickly wind the cable on the winding drum 1, and the length error of the cable on the full winding drum 1 is small. In addition, the length of the cable between the cutting device 8 and the winding drum 1 is short, so that the range of the cable after being cut off can be shaken, thereby reducing the risk of the cable hitting the operator.

[0049] Specifically, the cutting device 8 comprises a first sensor 12 and a cutting disc 10. The first sensor 12 is used to detect the working state of the winding drum 1, and the cutting disc 10 can cut off the cable passing through the cutting disc 10. Meanwhile, the cable winding device further comprises a control system and a second sensor. The second sensor is used to obtain the working parameters of the winding drum 1. The control system is electrically connected with the first sensor 12, the second sensor and the cutting disc 10. According to the working state of the winding drum 1 detected by the first sensor 12, the second sensor is controlled to work. According to the working parameters of the winding drum 1 obtained by the second sensor, the control system can control the cutting disc 10 and / or the winding drum 1 to work.

[0050] Through the detection of the working of the cable winding device by the first sensor 12 and the second sensor, the control system can automatically cut off the cable according to the working parameters detected by the first sensor 12 and the second sensor. The cable winding device reduces the manual participation during the working, reduces the labor cost, and improves the working efficiency. Meanwhile, the cutting of the cable is automatically executed by the control system controlling the cutting disc 10, which reduces the risk of the operator being hit by the cut-off cable, thereby protecting the safety of the operator.

[0051] Further, the control method of the cable winding device based on the above-mentioned embodiments comprises:

[0052] The cable winding device starts to work.

[0053] The first sensor 12 detects the winding drum 1 to determine whether the winding drum 1 is in a working state.

[0054] If the winding drum 1 is in a working state, the control system controls the second sensor to work.

[0055] Alternatively, if the winding drum 1 is in a non-working state, the control system controls to give a warning.

[0056] When the winding drum 1 is in normal operation, the control system controls the second sensor to work, and then controls the cutting disc 10 and / or the winding drum 1 to work according to the working parameters of the winding drum 1 obtained by the second sensor.

[0057] The working parameters include the tension of the cable, the winding length, and the winding speed. Specifically, the tension of the cable determines the tightness of the cable wound on the winding drum 1. The tightness of the cable wound on the winding drum 1 determines the length of the cable wound in a unit number of turns. The winding speed determines the tension of the cable and also determines the efficiency of the winding. The second sensor includes but is not limited to a tension sensor, an encoder 7, and a speed sensor. The corresponding working parameters can be detected by the corresponding sensors.

[0058] In the control method of the present application, the working parameters of the tension of the cable, the winding length, and the winding speed are monitored, so that the control system can more accurately detect the state of the cable on the winding drum 1, thereby improving the automation level of the cable winding device and improving the accuracy of the full-load winding drum 1. The accuracy of the full-load winding drum 1 refers to the consistency of the length of the cable on the full-load winding drum 1.

[0059] It should be noted that the control system includes at least a processor and a memory. The processor can include one or more CPUs, and each CPU in the processor can be a single-CPU or a multi-CPU. The processor herein can refer to one or more devices, circuits, and / or processing cores for processing data (e.g., computer program instructions). The processor can send working instructions to each functional component, so that each functional component works independently or cooperatively.

[0060] The memory is used to store the data in the present application and the computer execution instructions corresponding to the computer programs for executing the present application. The processor can realize various functions of the control element by running or executing the computer programs stored in the memory and calling the data stored in the memory.

[0061] Further, first, the first sensor 12 detects the winding drum 1 to determine whether the winding drum 1 is in a working state, including:

[0062] If the parameter detected by the first sensor 12 is consistent with or within the threshold value stored in the control system, it is determined that the winding drum 1 is in a working state. Otherwise, it is determined that the winding drum 1 is in an unworking state.

[0063] Specifically, the first sensor 12 is arranged in the cutting device 8. For example, the first sensor 12 determines whether the winding drum 1 is in a working state by detecting the movement speed of the cable passing through the cutting device 8.

[0064] Secondly, the working parameters of the winding drum 1 are acquired by the second sensor, and the control system controls the working of the cable cutting disc 10 and / or the winding drum 1, including:

[0065] In the case that the winding length of the cable on the winding drum 1 acquired by the second sensor is consistent with the threshold value stored in the control system, the control system controls the cable cutting disc 10 to cut the cable;

[0066] Alternatively, in the case that the tension of the cable on the winding drum 1 acquired by the second sensor, the winding and unwinding speed are consistent with the threshold value stored in the control system, the control system controls the winding drum 1 to rotate at a constant speed. Otherwise, the control system controls the winding drum 1 to accelerate or decelerate.

[0067] It can be understood that, since the control system can control the winding drum 1 to adjust the winding and unwinding speed, when the winding length of the cable on the winding drum 1 is close to or equal to the threshold value stored in the control system, i.e., before the control system controls the cable cutting disc 10 to cut the cable, the control system can also reduce the tension of the cable by reducing the rotating speed of the winding drum 1, thereby reducing the swing amplitude of the cable.

[0068] In some embodiments of the present application, in combination with Figure 3 、 4 , Figure 3 a sectional view of the cable cutting device in the cable winding device provided by some embodiments of the present application, Figure 4 a front view of the cable cutting device in the cable winding device provided by some embodiments of the present application. The cable cutting device 8 further comprises a cable cutting seat 11, and the cable cutting disc 10 is received on the cable cutting seat 11. The cable cutting disc 10 comprises a fixed ring 19, a rotating ring 20, and a plurality of arc-shaped cutters 21. The plurality of arc-shaped cutters 21 are rotationally connected to the rotating ring 20, and are slidingly connected to the fixed ring 19. The rotating ring 20 is slidingly connected to the fixed ring 19. Exemplarily, the rotating ring 20 is circumferentially provided with a sliding block 22, and the fixed ring 19 is provided with a groove matched with the sliding block 22. The sliding block 22 is embedded in the groove so as to facilitate the rotation of the rotating ring 20 relative to the fixed ring 19, and to avoid the deviation of the rotating ring 20 from the fixed ring 19.

[0069] Specifically, the fixed ring 19 is provided with a sliding groove 24, and the arc-shaped cutter 21 is provided with a limiting sliding column 23 matched with the sliding groove 24, and the limiting sliding column 23 can slide in the sliding groove 24. The sliding groove 24 extends towards the center of the fixed ring 19. When the rotating ring 20 rotates relative to the fixed ring 19, the arc-shaped cutters 21 can move along the limited direction of the sliding groove. At this time, the movement track of the arc-shaped cutters 21 is different from the rotating ring 20 and the fixed ring 19, so that the arc-shaped cutters 21 move along the limited direction of the sliding groove, the positions between the arc-shaped cutters 21 can be adjusted, so that the area of the arc-shaped cutters 21 coinciding with the hollow space of the rotating ring 20 and / or the fixed ring 19 changes. That is, the arc-shaped cutters 21 move to cut the cable.

[0070] More specifically, the fixed ring 19 and the rotating ring 20 are annular structures with hollow interiors, the edge of the arc-shaped cutter 21 is arranged towards the axis direction of the rotating ring 20 and / or the fixed ring 19, and when the rotating ring 20 rotates relative to the fixed ring 19, the area of the arc-shaped cutter 21 coinciding with the hollow space of the rotating ring 20 and / or the fixed ring 19 increases or decreases. When the area of the arc-shaped cutter 21 coinciding with the hollow space of the rotating ring 20 and / or the fixed ring 19 decreases, the arc-shaped cutter 21 is away from the cable, and the cable can move in the cable cutting disc 10. When the area of the arc-shaped cutter 21 coinciding with the hollow space of the rotating ring 20 and / or the fixed ring 19 increases, the arc-shaped cutter 21 is close to the cable and finally cuts the cable passing through the cable cutting disc 10.

[0071] The edge of the arc-shaped cutter 21 is the side of the arc-shaped cutter 21 used to cut the cable, and the force area of the edge on the cable is small, so that the cable is cut more quickly.

[0072] Exemplarily, the number of the arc-shaped cutters 21 is at least two, and the plurality of arc-shaped cutters 21 are circumferentially arranged on the rotating ring 20, and the edges of the plurality of arc-shaped cutters 21 form a cable cutting port, and the cable cutting port gradually expands or shrinks with the relative rotation of the fixed ring 19 and the rotating ring 20.

[0073] Further, as shown in Figure 1 and in combination with Figure 5 , Figure 5 a cross-sectional view of a wire feeding mechanism in a cable cutting device provided by some embodiments of the present application. The cable cutting device 8 further comprises a wire feeding mechanism 9, and the wire feeding mechanism 9 is located between the wire winding drum 1 and the cable cutting disc 10. Specifically, the wire feeding mechanism 9 is a cylindrical structure, and the wire feeding mechanism 9 is internally provided with a spiral-shaped protrusion to form a spiral groove. The cable passing through the cable cutting disc 10 moves in the spiral groove in the wire feeding mechanism 9, and the contact area between the spiral groove and the cable is large, thereby increasing the friction between the cable and the wire feeding mechanism 9. By increasing the friction between the cable and the wire feeding mechanism 9, after the cable is cut, the cable is difficult to swing due to the limitation of the wire feeding mechanism 9, thereby improving the safety.

[0074] Meanwhile, referring to Figure 6 , Figure 6 Figure 2 is a cross-sectional view of the cutting seat in the cutting device provided by some embodiments of the present application. The base 5 is provided with a transmission motor 25 and a cutting disc rotating motor 26. The cutting disc rotating motor 26 is connected with the rotating ring 20, and the rotating ring 20 is driven to rotate relative to the fixed ring 19 by the cutting disc rotating motor 26, so that the cutting disc 10 can cut off the cable. The transmission motor 25 is connected with the cable feeding mechanism 9, and the cable in the helical groove is driven to move by the rotation of the helical groove.

[0075] Further, as shown in Figure 1 , 2 , the cable winding device further comprises a motor 14, which is drivingly connected with the winding drum 1 through a transmission device. The winding drum 1 is driven to rotate by the motor 14. In this scheme, the winding drum 1 is driven to rotate by the motor 14 to wind and unwind the cable, and the transmission motor 25 drives the cable feeding mechanism 9 to drive the cable. By controlling the winding and unwinding speed of the cable and the speed of the cable driven by the cable feeding mechanism 9, the tension of the cable between the winding drum 1 and the cable feeding mechanism 9 can be adjusted.

[0076] In a specific embodiment, the transmission device comprises an input shaft 15, a universal joint 17 and an output shaft 16 connected in sequence, the output shaft 16 is connected with one end of the winding drum 1, and the input shaft 15 is installed on the power output end of the motor 14. The input shaft 15 and the output shaft 16 are connected through the universal joint 17, so that the angle between the input shaft 15 and the output shaft 16 can be adjusted, so that the axis direction of the motor 14 and the axis direction of the winding drum 1 can form a certain angle, so as to reduce the floor area of the whole device, and the whole cable winding device is more compact.

[0077] Meanwhile, the rolling bearing 2 is installed on the rotating shaft at both ends of the winding drum 1, and the bearing seat 3 is installed on the support frame 6, the rolling bearing 2 is carried on the bearing seat 3, and the connection between the winding drum 1 and the support frame 6 is completed, and the rolling bearing 2 can reduce the friction between the rotating shaft and the support frame 6 or the bearing seat 3 when the winding drum 1 rotates.

[0078] In some embodiments of the present application, the cable winding device further comprises a safety device 18, which is electrically connected with the control system, and the safety device 18 is used for detecting the failure of the cable winding device. When the cable winding device appears unexpected or failure, the safety device 18 can detect the corresponding accident and quickly respond to alarm to inform the operator, so as to ensure the safety of the device and the operator and reduce the loss caused by the accident.

[0079] Further, the cable winding device is provided with an operation interface for realizing interaction with the operator, and the operation interface can display information such as working parameters and / or working states, and allows the operator to control through buttons, switches or computer interfaces and the like.

[0080] For example, with reference to Figure 7 , Figure 7 The control system diagram of the cable winding device provided for some embodiments of the present application is shown. The working process of the cable winding device and the working process of the control system are as follows:

[0081] The driving motor 25 is started, and when the cable head enters the cable feeding mechanism 9 in the cable cutting device 8, it is conveyed to the cable cutting disc 10 by the cable feeding mechanism 9. At this time, the cable cutting disc rotating motor 26 is started, driving the rotating ring 20 to rotate forward, so that the arc-shaped cutting knives 21 move apart. At this time, a cable cutting port appears in the middle of the cable cutting disc 10, and the cable head passes through the cable cutting port. When the cable reaches the length that needs to be cut, the cable cutting disc rotating motor 26 drives the rotating ring 20 to rotate reversely, so that the arc-shaped cutting knives 21 are combined with each other, thereby cutting the cable and completing the cutting work.

[0082] The motor 14 is controlled to work by the control system to control the working of the winding drum 1, and the data of the winding drum 1 is transmitted to the control system. When the cable moves, the control system encoder 7 accurately monitors the position and motion state of the winding drum 1 and records the length of the cable collected by the winding drum 1. When the recorded cable length threshold is reached, the control system controls the cable cutting mechanism to work to cut the cable.

[0083] During the working process of the winding drum 1, the safety device 18 monitors and protects the cable winding device. When the safety device 18 detects an accident, it immediately stops the winding work and sends an alarm signal through the control system.

[0084] The safety device 18 includes, but is not limited to, an emergency stop switch, a collision sensor, a protector, and a safety door lock. Specifically:

[0085] Emergency stop switch: used to quickly cut off the power supply in emergency situations to avoid equipment damage or personal injury.

[0086] Collision sensor: used to detect whether the winding drum collides with other equipment or obstacles, thereby automatically stopping the winding movement and preventing further injury.

[0087] Overload protector: used to monitor the working state of the motor 14 or the transmission system, and automatically stop the equipment operation when the rated load or temperature range is exceeded, to avoid equipment damage or fire accidents.

[0088] Safety door lock: used to restrict the entry and exit of the device to ensure that only authorized personnel can perform the winding operation.

[0089] Cable breakage protector: used to monitor the tension state of the cable, and stop the device immediately when the cable breaks to prevent damage to the device or injury to personnel.

[0090] In this scheme, when an accident is detected by the detection element in the safety device 18, multiple elements in the safety device 18 can work together to reduce the loss of the accident.

[0091] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as within the scope of the present disclosure.

[0092] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be construed as limiting the scope of the patent application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of the patent of the present application should be subject to the appended claims.
