Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable packing equipment, in particular to an automatic cable coiling machine. BACKGROUND

[0002] The cable packing method mainly has a wheel type structure and a disc type structure, and high-voltage cables and BV cables basically use the wheel type structure because the wires are relatively hard; soft cables (BVR) use the wheel type structure, and on-site construction and transportation are not convenient, so the disc type structure is more common for packing, and the disc type structure has the advantages of convenient transportation, fast wire taking, simple construction, and no space occupation. The existing soft cable packing is normally performed by 2-3 people surrounding the coiled cable for transmission work, which has the following problems: 1. The shape is not fixed; 2. The efficiency is slow (2 people can complete 500-800 meters per hour); and 3. The upper and lower sizes are different (which is prone to collapse). SUMMARY

A lifting rope 66 is wound on the cable winding shaft 65.

[0048] A protective housing 67 is provided above the base plate 8, and one end of the lifting rope 66 is limited on the protective housing 67.

[0049] I. Overall Equipment Workflow: First, the cable is clamped by the traction roller 47 and extended downwards via the tension wheel on the tension rod 56. The cable passes sequentially below the second limiting roller 40, between the third limiting roller 42 and the fourth limiting roller 43, and is clamped between the main feed belt 34 and the secondary feed belt 35. The relative position between the second encoder 20 and the proportional cone 18 is manually adjusted according to the cable thickness. Then, the first pulse motor 21, the second pulse motor 22, and the output motor 4 are started. The output motor 4 drives the rotating ring 2 to rotate via the synchronous belt 7. During rotation, the driven wheel 17 drives the proportional cone 18 to rotate on the stationary ring 3. The proportional cone 18, during its rotation, drives the second encoder 20 to rotate on the stationary ring 3. Encoder 19 and second encoder 20 rotate. At the same time, under the action of second pulse motor 22 and second lead screw 29, first encoder 19 moves back and forth along proportional cone 18. During the movement, first encoder 19 emits pulses to control the speed of first pulse motor 21. Second pulse motor 22 and second lead screw 29 control first pulse motor 21 to move back and forth on first support crossbar 15 and second support crossbar 16 to achieve uniform coiling of the cable. The ratio of the movement distance of first encoder 19 on proportional cone 18 to the movement distance of first pulse motor 21 on first support crossbar 15 and second support crossbar 16 is equal to the ratio of the length of second lead screw and first lead screw 28.

[0050] After the cable is coiled to the width of the entire first lead screw 28, the lifting motor 63 drives the output system to move upward a certain distance via the lifting rope 66 (this distance is controlled according to the diameter of the cable). The above process is repeated until the cable is coiled to a certain height and then the operation stops.

[0051] In this embodiment, the cable is arranged in a spiral from the inside out or from the outside in until it reaches the innermost or outermost point, and then continues to spiral in the opposite direction, while the clockwise direction remains unchanged during the process.

[0052] In this embodiment, the output system is driven by a rotating system to rotate, thereby achieving automatic coiling of the cable. The output system can automatically adjust the movement distance of the first pulse motor 21 on the first lead screw 28 (for each coil of cable) according to the diameter of the coiled cable, thus ensuring the regularity of the finished product and high packaging efficiency, with consistent size from top to bottom. The lifting system can drive the rotating system and the output system to move upward. After each complete coil of cable, it moves upward a fixed distance, and the upward distance is controlled according to the cable diameter, so that the distance between the coils of cable is fixed, which also ensures the regularity of the finished product. The traction system can control the wire feeding speed through the traction roller 47, tension rod 56 and potentiometer 59. When the tension rod 56 moves downward, the coiling speed is reduced, and when the tension rod 56 moves upward, the coiling speed is increased.

[0053] II. Explanation of the working principle of the traction system: In this embodiment, the incoming line motor 49 and the rotating friction rod 61 cooperate to control the cable incoming speed. The rotating friction rod 61 is in contact with the drive shaft 48, and the friction between the rotating friction rod 61 and the drive shaft 48 is adjusted by rotating the rotating disk 62.

[0054] Before coiling, the tension rod 56 is manually rotated to keep it directly above the center of the stationary ring 3. After coiling begins, the tension rod 56 is pulled upward by the main feed belt 34, the secondary feed belt 35, and the traction roller 47. Since both the input motor 49 and the output motor 4 rotate at a constant speed, the tension rod 56 is held at a certain position and stops relatively. The tension rod 56 is tangent to the potentiometer 59 through a transmission wheel 60. The potentiometer 59 converts the position information of the tension rod 56 into an analog signal. When the input speed decreases, the tension rod 56 rotates downward, and the rotation speed of the output motor 4 and the movement speed of the first pulse motor 21 both decrease. When the input speed increases, the tension rod 56 rotates upward, and the rotation speed of the output motor 4 and the movement speed of the first pulse motor 21 both increase. When the tension rod 56 falls, both the output motor 4 and the first pulse motor 21 stop operating.

[0055] III. Please refer to Figure 12 The working principle of the output and rotary systems is explained as follows: The taper, length, and circumference of the proportional cone 18 are precisely calculated. The encoder position is automatically adjusted according to the size of the disc, and the circumference of the contact point between the proportional cone 18 and the encoder is measured. The setting of the proportional cone 18 can greatly reduce equipment investment costs, reduce equipment calculation delays, eliminate the need for recalibration upon restart, and accurately control the output cable length regardless of the output wheel's position.

[0056] The first pulse motor 21, the second pulse motor 22, the first encoder 19, the second encoder 20, the first lead screw 28, the second lead screw, the driven wheel 17, the proportional cone, etc. are all fixed on the rotating ring 2. Therefore, when the rotating ring 2 rotates, the above-mentioned components will rotate together. The stationary ring 3 plays the role of fixing the rotating ring 2, similar to a bearing.

[0057] Although the passive wheel 17 is set on the rotating ring 2, because its bottom rubs against the stationary ring 3, the passive wheel 17 will drive the proportional cone 18 to rotate while the rotating ring 2 rotates. The rotation of the proportional cone 18 will then drive the first encoder 19 and the second encoder 20 to rotate.

[0058] Since the first encoder 19 and the second encoder 20 are directly connected to the first pulse motor 21 and the second pulse motor 22, respectively, the pulses emitted by the rotation of the first encoder 19 and the second encoder 20 will directly drive the two pulse motors (in this embodiment, the first encoder 19 corresponds to the first pulse motor 21, and the second encoder 20 corresponds to the second pulse motor 22). In summary, as long as the rotating ring 2 rotates, the proportional cone 18 will rotate, and the two pulse motors will also rotate.

[0059] Explanation of the function of the cone: The cone simplifies complex program calculations. For example, when the first pulse motor 21 is on the outermost ring, the rotating ring 2 rotates once. The first pulse motor 21 needs to output 3 meters of cable. If this 3-meter cable requires 3000 pulses, then the first encoder 19 will output 3000 pulses. It is only necessary to calculate the circumference of the large circle of the proportional cone 18.

[0060] When the first pulse motor 21 is in the innermost circle, the rotating ring 2 rotates one revolution. The first pulse motor 21 needs to output 1 meter of cable. If this 1 meter of cable requires 1000 pulses, then the first encoder 19 should output 1000 pulses. It is only necessary to calculate the circumference of the small circle of the proportional cone 18. Thus, it can be concluded that the positions of the first pulse motor 21 and the first encoder 19 need to correspond, so that the circumference of the large and small circles of the cable can be calculated.

[0061] The following explains how to achieve the positional correspondence between the first pulse motor 21 and the first encoder 19: Firstly, the left and right movement of the first pulse motor 21 requires the second pulse motor 22 to be driven by the first lead screw 28. Similarly, the left and right movement of the first encoder 19 requires the second pulse motor 22 to be driven by the second lead screw 29. Therefore, the second pulse motor 22 needs to simultaneously drive both the first pulse motor 21 and the first encoder 19 to achieve their positional correspondence. That is, when the first pulse motor 21 moves from the outermost ring to the innermost ring, the first encoder 19 simultaneously moves from the large end to the small end of the cone; when the first pulse motor 21 moves from the innermost ring to the outermost ring, the first encoder 19 simultaneously moves from the small end to the large end of the cone. In this way, the first pulse motor 21 and the first encoder 19 are constantly linked and transmit pulses continuously.

[0062] In this embodiment, the moving distance of the first pulse motor 21 is four times the length of the proportional cone 18. Therefore, the lead of the first lead screw 28 is 4mm and the lead of the second lead screw 29 is 1mm to achieve speed change.

[0063] Explanation of the function of the second pulse motor 22: The second pulse motor 22 moves according to the diameter of the cable; for example, a cable with a diameter of 1cm needs to move 1cm inward or outward after one rotation. The task of the second pulse motor 22 is to make the first pulse motor 21 move inward by 1cm after one rotation. That is, the distance the second pulse motor 22 moves is determined by one rotation of the rotating ring 2; it does not suddenly move 1cm after one rotation, but rather completes this 1cm movement at a constant speed within one rotation cycle.

[0064] Explanation of how the second encoder 20 controls the movement of motor B: The two encoders differ in their movement patterns. The first encoder 19 moves continuously from left to right, while the second encoder 20 remains stationary and requires manual movement. For example, if the wire diameter is 1cm, move the second encoder 20 to the smaller end of the cone; if the wire diameter is 3cm, move the second encoder 20 to the larger end of the cone.

[0065] When the rotating ring 2 rotates once, the number of rotations of the driven wheel 17 and the proportional cone 18 is fixed. When the second encoder 20 is at the small end of the proportional cone 18, the number of rotations of the second encoder 20 is less and the number of fixed pulses is less because the contact circle between the second encoder 20 and the proportional cone 18 is small. When the second encoder 20 is at the large end of the cone, the number of rotations of the second encoder 20 is more and the number of fixed pulses is more because the contact circle between the second encoder 20 and the proportional cone 18 is large.

[0066] In summary, when the rotating ring 2 rotates, the first pulse motor 21 and the second pulse motor 22 rotate; when the rotating ring 2 stops, the first pulse motor 21 and the second pulse motor 22 stop; when the rotating ring 2 decelerates, the first pulse motor 21 and the second pulse motor 22 decelerate; when the rotating ring 2 accelerates, the first pulse motor 21 and the second pulse motor 22 accelerate; regardless of acceleration, deceleration, or stuttering, a good working effect is always achieved; when the first pulse motor 21 rotates, the tension rod 56 is raised; when the tension rod 56 is raised, the output motor 4 rotates; when the output motor 4 rotates, the rotating ring 2 rotates; when the rotating ring 2 rotates, the proportional cone 18 rotates; when the proportional cone 18 rotates, the two encoders rotate; the first encoder 19 controls the first pulse motor 21; the second encoder 20 controls the second pulse motor 22; the second pulse motor 22 causes the first pulse motor 21 and the first encoder 19 to perform proportional displacement; the entire process is completed and repeated cyclically.
