Description

Technical Field

[0001] The invention relates to the technical field of cable winding and moving, and in particular to a cable winding device for cable production. Background Art

[0002] When the existing cable reeling / winding device is used to wind the cable on the reel, the cable or cable is wound on the reel by the rotation of the reel. As the cable is continuously wound on the reel, the thickness (radial dimension) of the cable wound on the roller shaft of the reel will gradually increase, and when the thickness of the wound cable approaches the outer diameter of the end plate of the reel, the cable reeling operation is completed and a new reel needs to be replaced before the operation can be carried out.

[0003] In addition, when the existing cable winding device is used to wind the cable during the cable production process, as the cable winding thickness increases, the cable will tilt downward in its conveying direction, and the tilt angle will gradually increase. At that time, the length of the cable delivered per unit time should theoretically follow the change in real time. However, in practice, it is difficult to make up for the change in the length of the cable delivered in real time, so it is easy to cause a large change in the tension on the cable, which adversely affects the tightness of the cable wound on the roller and the regularity of the cable winding.

[0004] Although a spring-type tension adjustment mechanism is provided to push the cable and press the cable toward the axis of the roller, it can be used to adjust the tightness of the cable after it is rolled up during the winding operation and achieve a certain effect. However, in the case where the outer diameter of the end plate is relatively large and the outer diameter of the cable is relatively large, the thickness of the cable finally rolled up on the roller is also correspondingly large. As a result, when the cable thickness increases to a value close to the outer diameter of the end plate, the pushing effect of the spring-type tension adjustment mechanism becomes relatively weak. In addition, as the inclination degree increases due to the increase in the thickness of the cable, the pulling force on the cable increases significantly, which can easily cause the internal conductors or filling ropes of the cable to break or be mechanically damaged, thereby affecting the normal use, effect and life of the cable. Summary of the invention

[0005] The present invention provides a cable winding device for cable production, which can control the tilt amplitude of the cable during the cable winding operation to prevent the cable from being subjected to excessive pulling force during the winding process, help to improve the tightness of the cable wound into a roll, and help to improve the consistency of the tightness of the cable wound at different thickness positions.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a cable winding device for cable production, including a U-shaped support arm arranged on a base and used to support a winding roller, a lifting slide that can move in a vertical direction relative to the base, and a detection unit and a control unit.

[0007] End plates are formed on both ends of the roller shaft of the winding roller, and end shaft bodies are formed on both end surfaces of the roller shaft, so that the end plates are relatively located on the inner side of the end shaft body at the same end, that is, the two end plates are relatively located between the two end shaft bodies. A pair of arm plates facing each other front and back are formed on the upper part of the U-shaped support arm, and U-shaped notches corresponding to the two end shaft bodies are formed on the upper part of the two arm plates, so that the winding roller can be fixedly supported on the upper part of the U-shaped support arm and after matching with the externally arranged rotation drive unit, the winding roller can be selectively rotated relative to the U-shaped support arm to reel the cable onto the outer peripheral surface of the roller shaft.

[0008] A first U-shaped arm and a second U-shaped arm are formed on the upper part of the lifting slide, which are arranged alternately on the left and right, and the second U-shaped arm is close to the U-shaped support arm. A fixed roller and a rotating shaft body are matched between the arm plates of the first U-shaped arm, so that the pivot axis of the fixed roller and the axis of the rotating shaft body are both extended and arranged in the front-back direction, and the rotating shaft body is relatively arranged directly above the fixed roller, and a vertical spacing is formed between the outer peripheral surface of the rotating shaft body and the wheel surface of the fixed roller. The fixed roller can rotate relative to the first U-shaped arm around its pivot. Strip grooves extending in the vertical direction are respectively formed at the roots of the two arm plates of the second U-shaped arm, and a movable roller is matched between the strip grooves of the two arm plates. Shafts are respectively formed at the front and rear ends of the movable roller, and the shafts are matched with the strip grooves, so that the movable roller can be lifted and moved in the vertical direction along the strip groove relative to the arm plates of the second U-shaped arm. The outer diameter of the shaft is consistent with the width of the strip groove, and a matching relationship of line-surface contact is formed between the two.

[0009] The movable roller can rotate relative to the shaft around the axis of the shaft, so that it can rotate relative to the second U-shaped arm. However, the difference between the so-called fixed roller and the so-called movable roller is not whether they can rotate, but whether they can move up and down in the vertical direction relative to the U-shaped arm they match.

[0010] Axon bodies extending forward or backward may be formed on the free end surfaces of the two shaft rods respectively.

[0011] A pair of elastic support mechanisms facing each other are fixed on the lifting slide, so that the two elastic support mechanisms are matched with the two axle protrusions respectively, and can push the movable roller upward to keep it at the top / highest end of the lifting stroke, so that the top of the circumference of the fixed roller and the top of the circumference of the movable roller can be basically tangent to the same horizontal plane, that is, the height positions of the tops of the circumferences of the two rollers are basically at the same height level. If the axle protrusion is not set on the shaft rod, the elastic support mechanism is matched with the free end side of the shaft rod.

[0012] The detection unit includes a transmission rod and a sensor assembly. One end of the transmission rod is fixed on the shaft rod, specifically, it can be fixed on the free end face of the axon body. The sensor assembly is fixed on the outer end face of the arm plate of the first U-shaped arm. The other end of the transmission rod extends toward the first U-shaped arm and matches with the sensor assembly, so that when the end of the transmission rod fixed on the shaft rod moves along the vertical direction with the follower roller relative to the second U-shaped arm, the other end of the transmission rod can trigger the sensor assembly to send a real-time sensor signal. After processing the real-time feedback sensor signal, the control unit can control the movement of the lifting slide relative to the base to adjust the inclination of the cable relative to the horizontal direction.

[0013] In the initial state, the control unit controls the lifting slide to move upward, so that the top of the fixed roller contacts the lower side of the horizontally extending cable, and the bottom of the roller contacts the upper side of the horizontally extending cable. As the cable continues to be wound around the roller of the winding roller and the thickness continues to increase, the control unit can intermittently / intermittently move the lifting slide toward the base, that is, move downward by a certain amount of stroke, to continuously adjust the inclination of the cable relative to the horizontal direction, so that the inclination angle / amplitude of the cable relative to the horizontal direction can always be kept within a preset range.

[0014] Optionally, the sensing assembly includes a sensor body, a movable portion, a disc-shaped body and a rotating block.

[0015] The disc-shaped body is fixed on the arm plate of the first U-shaped arm part, and the rotating block is pivotally matched with the disc-shaped body so that the rotating block can rotate relative to the disc-shaped body around an axial direction extending in the front-rear direction. A radial through hole is formed on the rotating block, and the other end of the transmission rod is inserted into the radial through hole on the rotating block, and the free end of the transmission rod is preferably inserted out of the radial through hole so that the other end of the transmission rod can always remain in a state of being inserted into the radial through hole.

[0016] The sensor body is fixed on the end surface of the disc-shaped body, and the movable part is fixed on the side of the rotating block. The movable part extends into the sensor body and can match with the sensing part of the sensor body. When the movable part rotates with the rotating block, it can trigger the sensor body to generate a sensing signal.

[0017] Optionally, the sensor assembly is a grating sensor assembly, and the sensor body is a grating sensor body. The moving grating in the grating sensor assembly is fixed on the movable part, and the moving grating is matched with the fixed grating on the grating sensor body.

[0018] When the movable part rotates synchronously with the rotating block, it can carry the movable grating to move relative to the fixed grating on the grating sensor body, so that the grating sensor assembly generates a sensing signal.

[0019] Optionally, the sensing assembly is a capacitive sensing assembly, and the sensor body is a capacitive sensor body. The medium carrier / filling medium carrier in the capacitive sensing assembly is fixed on the movable part, and the medium carrier is matched with the electrode plate (spacing position) on the capacitive sensor body. When the movable part and the rotating block rotate synchronously, it can carry the medium carrier to move relative to the electrode plate on the capacitive sensor body, so that the amount of dielectric medium on the medium carrier corresponding to the electrode plates changes in real time, so as to prompt the capacitive sensing assembly to generate a sensing signal.

[0020] Optionally, the elastic support mechanism includes a connecting rod, a spring, a sliding block and a bolt, and correspondingly, a transverse plate portion 1 and a transverse plate portion 2 which are arranged alternately up and down are formed on the lifting slide.

[0021] The connecting rod is arranged in the vertical direction and a radial flange is formed in the middle of the connecting rod. The upper end of the connecting rod is fixedly connected to the shaft rod, and the spring sleeve is arranged at the lower part of the connecting rod. When an axle body is provided, the upper end of the connecting rod can be fixedly connected to the axle body.

[0022] The slider and the horizontal plate part 1 are matched through a track structure arranged in the vertical direction, so that the slider can move up and down relative to the horizontal plate part 1 or relative to the lifting slide. A countersunk hole is formed on the upper end surface of the slider and the lower end of the connecting rod extends into the countersunk hole, so that a vertical spacing is formed between the lower end surface of the connecting rod and the inner bottom surface of the countersunk hole.

[0023] The two ends of the spring are in contact with the lower end of the radial flange and the upper end surface of the slider, respectively, and can exert an upward elastic thrust on the shaft through the connecting rod. The bolt and the second cross plate are matched through a threaded structure, so that the bolt can drive the slider to move in the vertical direction, and the elastic thrust of the spring on the shaft can be adjusted.

[0024] Optionally, it further includes a translation slide matched with the base through a track structure arranged in the front-to-back direction, so that the translation slide can move relative to the base in the front-to-back direction. A platform is fixedly provided on the translation slide, and a track structure arranged in the vertical direction is provided on the platform to match the lifting slide, so that the lifting slide can move relative to the platform in the vertical direction. The control unit can control the movement states of the translation slide and the lifting slide respectively.

[0025] Optionally, a pivot seat is fixedly provided on the base. The lower part of the U-shaped support arm matches the pivot seat, so that the U-shaped support arm can rotate relative to the pivot seat in a vertical plane extending in the left-right direction. A gear portion is formed at the lower part of the U-shaped support arm, which can be an incomplete gear portion. A screw slider transmission assembly is provided on the base, and a rack is fixedly provided on the slider body of the screw slider transmission assembly, and the rack is meshed with the gear portion, so that the screw slider transmission assembly can drive the U-shaped support arm to rotate relative to the pivot seat in the vertical plane.

[0026] Optionally, a limit block is provided on the upper part of the pivot seat. The limit block can limit the stroke position of the U-shaped support arm rotating toward the lifting slide side, so that when the U-shaped support arm rotates toward the lifting slide side to the end of its stroke, the U-shaped support arm is stopped in an upright state. A travel switch can be provided on the limit block. When the U-shaped support arm rotates to the upright position, the travel switch can be pressed, so that the control unit sends an action instruction to the screw slider transmission assembly, so that the screw slider transmission assembly stops continuing to drive the rack to slide in the left and right directions, so that the U-shaped support arm stops rotating.

[0027] Optionally, a rotary bevel platform is provided on the base and on the side of the U-shaped support arm away from the lifting slide, and the inclined surface of the rotary bevel platform is extended downwardly toward the side away from the U-shaped support arm.

[0028] The beneficial effects of the present invention are as follows: the present invention can effectively control the degree of inclination of the cable relative to the horizontal direction during the cable winding operation, that is, the angle at which the cable is tilted downward relative to the horizontal direction, and can prevent the cable from being subjected to excessive pulling force when it is wound onto the winding roller; and can improve the consistency of the tightness of the cable wound on the winding roller, so that the wound cable can be maintained in a better clamped state, compact and uniform, and is not prone to loose deformation during transportation.

[0029] In addition, by moving the cable along the axis of the winding roller or roller shaft as the winding progresses during the winding / reeling process, the regularity of the cable wound on the winding roller can be improved, making the cable winding distribution more uniform and compact.

[0037] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical contents.

[0038] like Figures 1 to 6 The cable winding device shown is for cable production, comprising a U-shaped support arm 20 disposed on a base 10 and used for fixing and supporting a winding roller 200, a slide 30 (i.e., a translation slide) capable of moving in a front-to-rear direction relative to the base 10, a slide 40 (i.e., a lifting slide) capable of moving up and down relative to the base 10, and a detection unit 50.

[0039] The winding roller 200 of the present invention is the same as or similar to the existing winding roller 200, and includes a roller shaft 201 and a pair of end plates 202 arranged at both ends of the roller shaft 201. In addition, in the scheme of the present invention, end shaft bodies 203 are respectively formed on the end faces of both ends of the roller shaft 201, and a facet countersunk hole 204 is formed on the end face of at least one of the end shaft bodies 203. The end shaft body 203 matches the U-shaped notch 21 formed on the upper part of the arm plate of the U-shaped support arm 20, and the winding roller 200 is fixedly mounted on the arm plate of the U-shaped support arm 20, and the two end plates 202 are respectively close to the two arm plates of the U-shaped support arm 20, and are relatively located between the inner sides of the two arm plates.

[0040] The externally arranged driving unit (not shown in the figure) achieves the driving purpose of driving the winding roller 200 to rotate relative to the U-shaped support arm 20 by selectively matching (making its transmission shaft) with the edge countersunk hole 204, so as to make the cable 100 wind around the roller shaft 201 of the winding roller 200. In the scheme of the present invention, between the winding roller 200 and the U-shaped support arm 20, an associated structure is established to match the winding roller 200 and the U-shaped support arm 20, and between the externally arranged driving unit and the winding roller 200, an associated matching structure is established to enable the externally arranged driving unit to drive the winding roller 200 to rotate. The above-mentioned scheme can be adopted, or a suitable structure can be selected from the existing technical schemes with reference to the prior art, as long as the winding roller 200 can rotate relative to the U-shaped support arm 20 around a horizontal axis extending in the front-to-back direction, and the externally arranged driving unit can selectively establish a matching relationship with the winding roller 200 to drive the winding roller 200 to rotate relative to the U-shaped support arm 20.

[0041] A pivot seat 11 is fixedly provided on the base 10. The lower portion of the U-shaped support arm 20 matches the pivot seat 11, so that the U-shaped support arm 20 can rotate relative to the pivot seat 11 in a vertical plane extending in the left-right direction.

[0042] An incomplete gear part 22 is formed at the lower part of the U-shaped support arm 20. A lead screw slider transmission assembly 13 is provided on the base 10, and a rack 131 is fixedly provided on the slider body of the lead screw slider transmission assembly 13, and the rack 131 is meshed with the incomplete gear part 22, so that the lead screw slider transmission assembly 13 can drive the U-shaped support arm 20 to rotate in a vertical plane relative to the pivot seat 11. The rack 131 and the base 10 are matched through a slide rail structure arranged in the left and right direction, so that the rack 131 can be driven by the lead screw slider transmission assembly 13 and slide in the left and right direction relative to the base 10.

[0043] A limit block 12 is provided on the upper part of the pivot seat 11. The limit block 12 can limit the stroke position of the U-shaped support arm 20 rotating toward the left side, so that when the U-shaped support arm 20 rotates toward the left side (i.e., the side of the slide seat 2 40) to the end of its stroke, the U-shaped support arm 20 can be stopped in an upright state. A travel switch can be provided on the limit block 12. When the U-shaped support arm 20 rotates to the upright state, the travel switch can be pressed, so that the control unit can control the screw slider transmission assembly 13 to stop driving the rack 131 to slide. Therefore, the travel switch is connected to the control circuit of the screw slider transmission assembly 13 and is associated with the control unit.

[0044] A rotating bevel table 14 is provided on the right side of the base 10 and outside the right side of the U-shaped support arm 20, and the bevel of the rotating bevel table 14 is extended downwardly and tilted toward the right side. After the cable 100 wound on the winding roller 200 reaches the thickness requirement, the lead screw slider transmission assembly 13 drives the U-shaped support arm 20 to rotate toward the right side, and basically rotates to a nearly horizontal state. The curved surface of the end plate 202 of the winding roller 200 can contact the bevel of the rotating bevel table 14, so that the winding roller 200 with the cable 100 wound can be easily removed from the U-shaped support arm 20, and quickly and labor-savingly transferred to the next process.

[0045] The slide 2 40 is matched with the upper part of the slide 1 30, so that the slide 2 40 can move up and down relative to the slide 1 30, and the slide 2 40 can move up and down relative to the base 10. In the illustrated scheme, the slide 1 30 is matched with the base 10 through a track structure arranged along the front-to-back direction, and the slide 1 30 is driven by the set driving unit 1 31 to move linearly along the front-to-back direction relative to the base 10. The slide 2 40 is matched with the stand 32 arranged on the upper part of the slide 1 30, and the stand 32 is provided with a track structure extending in the vertical direction to match the slide 2 40, and the set driving unit 2 41 drives the slide 2 40 to move up and down relative to the stand 32 or relative to the slide 1 30 / the base 10 in the vertical direction. The driving unit 1 31 and the driving unit 2 41 can both be selected to be used as ball screw transmission units, and the travel direction and travel amount of the slide 1 30 and the slide 2 40 can be regulated by controlling the speed and direction of the motors in the two driving units.

[0046] A first U-shaped arm portion 42 and a second U-shaped arm portion 43 are alternately arranged on the left and right sides of the upper portion of the slide seat 2, and the second U-shaped arm portion 43 is relatively close to the U-shaped support arm 20.

[0047] A fixed roller 421 and a rotating shaft body 422 are matched between the front and rear arm plates of the first U-shaped arm portion 42. The pivot axis of the fixed roller 421 and the axis of the rotating shaft body 422 are both arranged to extend in the front-back direction and the rotating shaft body 422 is relatively arranged directly above the fixed roller 421, and a vertical gap is formed between the outer peripheral surface of the rotating shaft body 422 and the wheel surface of the fixed roller 421 for the cable 100 to pass through.

[0048] Strip grooves 432 extending in the vertical direction are respectively formed at the roots of the front and rear arm plates of the second U-shaped arm portion 43 , and a movable roller 431 is matched between the strip grooves 432 of the two arm plates.

[0049] The extension length of the strip groove 432 in the vertical direction is greater than the outer diameter of the shaft rod 433. Generally, the vertical length of the strip groove 432 is in the range of 1.2 times to 3 times the outer diameter of the shaft rod 433, so as to provide sufficient travel space for the shaft rod 433 or the movable roller 431 to move downward relative to the arm plate of the second U-shaped arm portion 43.

[0050] Axles 433 extending in the front-to-back direction are formed on the front and rear end surfaces of the movable roller 431, respectively, and the two axles 433 are matched with the two strip grooves 432, so that the movable roller 431 can move in the vertical direction relative to the arm plate of the second U-shaped arm 43 along the strip grooves 432. The outer diameter of the axle 433 is consistent with the width of the strip groove 432, and the two form a matching relationship of line-surface contact. Axon protrusions 434 extending forward or backward are formed on the free end surfaces of the two axles 433.

[0051] A pair of elastic support mechanisms are fixedly provided on the slide 40 in a front-to-rear direction, so that the two elastic support mechanisms are matched with the two axle protrusions 434 respectively, so that the elastic support mechanisms can push the movable roller 431 upward to move to the top / highest end position of its stroke, and can basically maintain this height position (during use). At that time, the top of the circumference of the fixed roller 421 and the top surface of the circumference of the movable roller 431 can be basically at the same horizontal height position, that is, the height position of the top of the circumference of the two rollers is basically the same.

[0052] like Figures 1 to 6 As shown, the elastic support mechanism includes a connecting rod 435, a spring 436, a slider 437 and a thrust screw 438, and correspondingly, a horizontal plate portion 1 and a horizontal plate portion 2 arranged alternately up and down are formed on the slide seat 2 40.

[0053] The connecting rod 435 is arranged in a vertical direction and a radial flange 4351 is formed in the middle of the connecting rod 435. The upper end of the connecting rod 435 is fixedly connected to the axle protrusion 434 and the spring 436 is sleeved on the lower part of the connecting rod 435.

[0054] The slider 437 is matched with the horizontal plate part 1 through a track structure arranged in the vertical direction, so that the slider 437 can move up and down relative to the horizontal plate part 1 or relative to the slide seat 2 40. A countersunk hole is formed on the upper end surface of the slider 437, and the lower end of the connecting rod 435 extends into the countersunk hole, and a vertical spacing is maintained between the lower end surface of the connecting rod 435 and the inner bottom surface of the countersunk hole. The size of the vertical spacing should meet the travel space requirement of the movable roller 431 moving downward, that is, it should be able to prevent the vertical spacing between the lower end of the connecting rod 435 and the opposite surface of the countersunk hole from interfering and hindering the movable roller 431 from moving downward. In the initial state, a vertical spacing is also maintained between the lower part of the circumference of the shaft rod 433 and the bottom of the strip groove 432.

[0055] The two ends of the spring 436 are in contact with the lower end surface of the radial flange 4351 and the upper end surface of the slider 437, respectively, so that the spring 436 can exert an upward elastic thrust on the connecting rod 435 to support the movable roller 431 to lean against the upper end side of the strip groove 432. The thrust screw 438 and the horizontal plate part 2 are matched through a threaded structure, so that the thrust screw 438 can drive the slider 437 to move upward in the vertical direction. By screwing the thrust screw 438 to adjust the matching position between the screw body of the thrust screw 438 and the horizontal plate part 2, the thrust screw 438 and the spring 436 can jointly exert a force on the slider 437 to adjust the height position of the slider 437 and the compression state of the spring 436. In the illustrated scheme, a rotary column block is disposed at the upper end of the thrust screw 438 and the upper end of the rotary column block is embedded in the lower part of the slider 437, so that the rotary column block is fixedly connected to the slider 437 and can rotate around the vertical axis relative to the slider 437. The lower part of the rotary column block is connected to the upper end of the screw body of the thrust screw 438.

[0056] like Figures 1 to 6As shown, the detection unit 50 includes a transmission rod 51 (or a rocker rod) and a sensor assembly 52. ​​One end of the transmission rod 51 (the right end in the figure) is fixed on the shaft rod 433, and is specifically fixed on the free end face of the axle body 434 in the figure. The sensor assembly 52 is fixed on the outer side (front side in the figure) end face of the arm plate of the first U-shaped arm 42. The other end of the transmission rod 51 (the left end in the figure) extends toward one side (left side) of the first U-shaped arm 42 and matches with the sensor assembly 52, so that when the right end of the transmission rod 51 moves synchronously with the movable roller 431 in the vertical direction relative to the second U-shaped arm 43, the left end of the transmission rod 51 can enable the sensor assembly 52 to send a real-time changing sensor signal. After processing the real-time feedback sensor signal, the control unit can control the slide 2 40 to move in the vertical direction relative to the base 10 or the stand 32 of the slide 1 30 to control the tilt amplitude of the cable 100 relative to the horizontal direction, so that the tilt angle of the cable 100 is controlled within a preset range.

[0057] like Figure 1 to Figure 2 , Figures 4 to 6 As shown, the sensor assembly 52 includes a sensor body 521 , a movable portion 522 , a disc-shaped body 53 and a rotating block 531 (or a rotating block).

[0058] The disk-shaped body 53 is fixed on the end surface of the arm plate of the first U-shaped arm portion 42. The rotating block 531 is pivotally matched with the disk-shaped body 53 and enables the rotating block 531 to rotate relative to the disk-shaped body 53 around an axial direction extending in the front-rear direction. A radial through hole is formed on the rotating block 531, and the left end of the transmission rod 51 is inserted into the radial through hole on the rotating block 531, and the left free end of the transmission rod 51 is preferably inserted outside the radial through hole for a certain length. Specifically, a light column segment 511 is formed at the left end of the transmission rod 51, so that the light column segment 511 matches the radial through hole on the rotating block 531.

[0059] The sensor body 521 is fixed on the end face of the disc-shaped body 53, and the movable part 522 is fixed on the side face of the rotating block 531, and the movable part 522 extends into the sensor body 521 and can match with the sensing part of the sensor body 521, so that when the movable part 522 rotates with the rotating block 531, it can trigger the sensor body 521 to generate a sensing signal in real time.

[0060] In the initial state, the axis line OO of the transmission rod 51 can be basically in the horizontal plane. Therefore, at this time, the axis of the radial through hole on the rotating block 531 is along the horizontal direction, see Figure 1 , Figure 2When the thickness of the cable 100 wound on the roller 201 increases to a certain extent, the cable 100 can be pulled to tilt downward, so that the cable 100 exerts a pressure F on the upper part of the movable roller 431, and as the downward tilt of the cable 100 increases, the pressure F will gradually increase, and can push the movable roller 431 to move downward, and then carry the right end of the transmission rod 51 to move downward, so that the axis OO of the transmission rod 51 is tilted relative to the horizontal direction and offset to the position O1-O1, and a deflection angle a is formed between the axis OO and O1-O1, see Figure 4 During this period, the left end of the transmission rod 51 drives the rotating block 531 to rotate relative to the disc-shaped body 53 (clockwise), thereby causing the movable part 522 to shift relative to the sensing part on the sensor body 521, thereby generating a real-time changing sensing signal.

[0061] The transmission rod 51 can be a straight rod as shown in the figure; in other embodiments, it can also be set to a bent rod, or even to increase the rotation angle of the left end driving the rotating block 531 to rotate when the right end is lifted and moved downward, that is, to relatively increase the rotation amount of the rotation angle, the transmission rod 51 can also be set to an arc rod, or a connecting rod mechanism, or a connecting rod slider mechanism and other deformed structural forms. Therefore, in the technical solution of the present invention, the transmission rod 51 should be interpreted in an expanded manner.

[0062] The sensor assembly 52 can be selected as a grating sensor assembly, a capacitive sensor assembly, or other forms.

[0063] When the grating sensor assembly is selected, the sensor body 521 is a grating sensor body. The moving grating in the grating sensor assembly is fixed on the movable part 522, and the moving grating is matched with the fixed grating on the grating sensor body. When the movable part 522 and the rotating block 531 rotate synchronously, the movable part 522 can carry the moving grating to change / move relative to the fixed grating on the grating sensor body, so that the grating sensor assembly generates a real-time sensing signal.

[0064] When the capacitive sensor assembly is selected, the sensor body 521 is a capacitive sensor body. The medium carrier or the filling medium carrier in the capacitive sensor assembly is fixed on the movable part 522, and the medium carrier is matched with the electrode plate on the capacitive sensor body. When the movable part 522 and the rotating block 531 rotate synchronously, the movable part 522 can carry the medium carrier to move relative to the electrode plate on the capacitive sensor body, so that the amount of dielectric medium on the medium carrier corresponding to the (two) electrode plates changes in real time, so as to prompt the capacitive sensor assembly to generate a sensing signal, that is, the capacitive sensor assembly adopted is a medium-changing type.

[0065] The control unit intermittently controls the slide 2 40 to move downward by a certain amount according to the change of the sensor signal, which is a control method of timed quantitative movement. In specific implementation, the control unit can also continuously control the slide 2 40 to move downward according to the change of the sensor signal, which is a control method of non-quantitative movement.

[0066] The detection unit 50 may include only one set of sensing detection mechanisms such as a transmission rod 51 and a transmission assembly 52, or may include two sets of sensing detection mechanisms such as a transmission rod 51 and a transmission assembly 52. ​​When two sets of sensing detection mechanisms such as a transmission rod 51 and a transmission assembly 52 are provided, the two transmission rods 51 are arranged front and back opposite to each other, and the two ends of the two transmission rods 51 are matched with the front end surface of the first U-shaped arm portion 42 and the front end surface of the second U-shaped arm portion 43, respectively (e.g., Figure 1 , Figure 4 As shown), and respectively match the rear end surface of the first U-shaped arm portion 42 and the rear end surface of the second U-shaped arm portion 43 (the view in this direction is not shown).

[0067] In the initial state, the control unit controls the slide 2 40 to move upward (to the initial position), when the top of the circumference of the fixed roller 421 is in tangential contact with the lower side of the horizontally extending cable 100, and the bottom of the circumference of the roller shaft 201 is in tangential contact with the upper side of the horizontally extending cable 100. As the cable 100 is continuously wound on the roller shaft 201 of the winding roller 200 and the winding thickness continues to increase, the control unit can intermittently move the slide 2 40 downward by a certain amount of stroke to continuously regulate the inclination of the cable 100 relative to the horizontal direction, so that the inclination angle / inclination amplitude of the cable 100 relative to the horizontal direction can always be maintained within the preset (deflection) range.

[0068] The control unit is matched with the set drive unit 1 31, drive unit 2 41, screw slider transmission assembly 13, travel switch provided on the limit block 12, and the external drive unit for driving the winding roller 200 to rotate. The control unit can control the slide 1 30 to reciprocate in the front-to-back direction (at a constant speed or at a speed that changes regularly) relative to the base 10, can control the slide 2 40 to intermittently move downward in the vertical direction (preset fixed stroke amount) and quickly move upward to the initial position relative to the stand 32, can control the external drive unit to switchably establish a connection matching relationship and a disconnection relationship with the end shaft 203, and after establishing the connection matching relationship, can control the external drive unit to drive the winding roller 200 to rotate, and can control the screw slider transmission assembly 13 to drive the U-shaped support arm 20 to rotate in the vertical plane in the left-right direction.

[0069] In summary, the present invention controls the angle of inclination of the cable 100 relative to the horizontal direction, and during the production process of the cable 100, the cable 100 is basically kept in the horizontal feeding direction, which can relatively reduce the factors affecting the feeding amount / feeding speed V, the pulling force, etc. of the cable 100 during the winding process, and reduce the difficulty of analysis and calculation. Generally, it is only necessary to mainly adjust the feeding speed / feeding amount of the cable 100 per unit time according to the thickness change law of the cable 100 wound on the winding roller 200, the rotation speed of the winding roller 200, etc., so as to easily achieve the feeding amount, and effectively prevent the cable 100 from being subjected to excessive pulling force, so that the cable 100 wound on the winding roller 200 is kept in a suitable tight state, and the winding tightness of the cable 100 wound at different thickness positions has good consistency, and the winding distribution state is more uniform and compact. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance.
