Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and in particular to cable laying and laying mechanisms. Background Technology

[0002] Linear transmission materials such as optical cables and electrical cables are collectively referred to as cables. During the manufacturing process of cables, it is necessary to lay them out, which means rolling the cables layer by layer, tightly and neatly, onto a cable reel. The laying out of cables must meet requirements such as neatness, no wire overlap, and a flat appearance.

[0003] In the prior art, a reciprocating cable guide wheel mechanism is usually installed between the cable laying mechanism and the cable feeding mechanism. The cable is released from the feeding mechanism, passes through the cable guide wheel mechanism, and is wound on the cable laying mechanism. The motors of the cable laying mechanism and the feeding mechanism are started respectively. The cable moves with the guide wheel cable laying mechanism and is laid on the cable laying mechanism.

[0004] However, because the guide wheel is constantly moving, the required cable length between the wire feeding mechanism and the wire laying mechanism varies, resulting in constantly changing tension on the cable. This leads to inconsistent cable tension on the laying reel during laying, causing uneven laying. Simultaneously, since the rotation speeds of the wire feeding and laying mechanisms are fixed, and the wire feeding mechanism lays less and less cable while the laying mechanism lays more and more cable, at the same rotation speed, the wire fed per revolution by the wire feeding mechanism becomes shorter, while the wire laid per revolution by the laying mechanism becomes longer. This results in initially lower tension on the cable, leading to a loose laying of cable by the laying mechanism. As time progresses, the pressure on the cable increases, and the laying mechanism tightens the cable, causing uneven laying on the laying mechanism and increasing tension on the cable, which can damage the cable.

[0007] The technical solution of the present invention has the following advantages compared with the prior art: The cable on the cable feeding mechanism of this invention passes through the cable guide wheel mechanism and is wound around the cable support. A proximity switch sensor transmits a signal to the PLC controller, which controls the rotation direction of the servo motor. The servo motor moves the cable support. The time it takes for the cable reel to rotate one revolution is equal to the diameter distance the cable support moves on the cable guide screw. This prevents the cable from being subjected to tension due to the movement of the cable support. The proximity switch sensor sends an electrical signal to the PLC controller, which, while controlling the servo motor, also controls the rotation speed of the servo motor and the cable feeding mechanism based on the diameter of the cable. This ensures that the length of cable fed by the cable feeding mechanism in the same time period is approximately the same as the length of cable laid by the cable reel. This also ensures that the tension on the cable on the cable reel is uniform, resulting in even cable laying on the reel. During operation, the PLC controller supplies energized power to the two limit electromagnets, causing the two limit plates to limit the cable as the cable tray moves in different directions, resulting in neater cable routing. The distance between the two limit brackets is controlled by bolts, allowing the two limit brackets to be adjusted according to the cable diameter, enabling the limit plates to more precisely limit the cable. The movement of rollers on the slide rails reduces the resistance of the cable tray screw driving the cable tray. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0012] Reference Figures 1-6 As shown, the cable laying and routing mechanism includes a base 1; In one embodiment of the present invention, the base 1 has two ends fixedly connected to first brackets 2; one of the first brackets 2 is fixedly connected to a servo motor 3; an external PLC controller is fixedly connected to the first bracket 2; a lead screw 4 is fixedly connected to the output end of the servo motor 3; the lead screw 4 is located between two of the first brackets 2; and the lead screw 4 is rotatably connected to each of the first brackets 2; a lead screw 5 is threadedly connected to the lead screw 4; the lead screw 5 is slidably connected to the base 1; the lead screw 5 is located between two of the first brackets 2; a first [unclear - possibly a component or device] is fixedly connected to one side of the lead screw 5. Two motors 6; a cable tray 7 is fixedly connected to the output end of the second motor 6; a limit assembly 8 is connected to the base 1; the limit assembly 8 is located in the middle of the two first brackets 2; a proximity switch sensor 9 is fixedly connected to each first bracket 2; the sensing surface of the proximity switch sensor 9 faces the cable tray 5; a cable guide wheel mechanism 10 is connected to the base 1; the cable guide wheel mechanism 10 is located on the right side of the first bracket 2; a cable feeding mechanism 11 is connected to the base 1; the cable feeding mechanism 11 is located on the right side of the cable guide wheel mechanism 10; the cable guide wheel mechanism 10 is located between the cable feeding mechanism 11 and the first bracket 2; During operation, the cable from the cable feeding mechanism 11 passes through the cable guide wheel mechanism 10 and winds onto the cable support 5. The servo motor 3 is activated; its output drives the cable guide screw 4 to rotate, causing the cable support 5 to move. The cable released from the cable feeding mechanism 11 passes sequentially through the cable guide wheel mechanism 10 and the limiting component 8 onto the moving cable reel 7. The time it takes for the cable reel 7 to rotate once is equal to the diameter distance the cable support 5 moves on the cable guide screw 4, preventing the cable from being pulled by the movement of the cable support 5. When the cable support 5 moves closer to one of the first supports 2, this... The proximity switch sensor 9 of the first bracket 2 senses the cable tray 5 and transmits an electrical signal to the PLC controller. The PLC controls the servo motor 3 to change its rotation direction, causing the cable tray screw 4 to rotate in the opposite direction, thereby moving the cable tray 5 in the opposite direction. While controlling the servo motor 3, the PLC controller also controls the rotation speed of the servo motor 3 and the cable feeding mechanism 11 according to the diameter of the cable. This ensures that the length of the cable fed by the cable feeding mechanism 11 in the same time period is basically the same as the length of the cable in the cable tray 7. This makes the tension on the cable in the cable tray uniform and the cable feeding on the cable tray 7 uniform. The limiting assembly 8 includes a limiting bracket 81; one of the limiting brackets 81 is fixedly connected to the base 1; each limiting bracket 81 has a hole 82; the lead screw 4 passes through the hole 82; a limiting groove 83 is formed at the upper end of the limiting bracket 81; the opening of the limiting groove 83 faces upward; a limiting plate 84 is slidably connected to the inner side wall of the limiting groove 83; an electromagnet 85 is fixedly installed at the bottom of the limiting groove 83; an iron plate 86 is installed at the bottom of the limiting plate 84; a spring 87 is connected between the electromagnet 85 and the iron plate 86; one end of the spring 87 is fixedly connected to the electromagnet 85; the other end of the spring 87 is fixedly connected to the iron plate 86. During operation, the cable is passed between the two limit brackets 81 and wound onto the cable tray 7. When the cable tray 5 begins to move towards the first bracket 2 on the left, the electromagnet 85 on the left is energized, causing the iron plate 86 on the left to be attracted to the electromagnet 85 by magnetic force. This compresses the spring 85 on the left, preventing the limit plate 84 on the left from contacting the cable tray. The electromagnet 85 on the right is not energized, and the top of the limit plate on the right is in contact with the cable tray. When the proximity switch sends an electrical signal, the PLC controller controls the electromagnet 85 on the left to be de-energized. Due to the elastic force of the spring, the limit plate 84 on the left moves upward and contacts the cable that was just laid out. At the same time, the PLC controller controls the electromagnet 85 on the right to be energized, and the limit plate 84 on the right moves downward due to magnetic force. By energizing the two electromagnets 85 alternately, the two limit plates 84 limit the cable when the cable tray 5 moves in different directions, making the cable laying neater. The base 1 and the other limiting bracket 81 are slidably connected; the limiting bracket 81 is threaded with a number of bolts 88; the two limiting brackets 81 are connected by the bolts 88. During operation, the distance between the two limit brackets 81 is controlled by bolt 88, allowing the two limit brackets 81 to be adjusted according to the diameter of the cable, and enabling the limit plate 84 to more accurately limit the cable. A plurality of sliding rods 89 are fixedly connected to each of the limiting grooves 83; one end of the sliding rod 89 is fixedly connected to the bottom of the limiting groove 83; the other end of the sliding rod 89 passes through the limiting plate 84; and the sliding rod 89 is slidably connected to the limiting plate 84. During operation, the sliding rod 89 restricts the movement direction of the limiting plate 84; The base 1 is provided with a slide rail 12; the slide rail 12 is located between the two first brackets 2; the cable bracket 5 is provided with a plurality of roller grooves 13; a roller 14 is rotatably connected in the roller groove 13 and is in sliding contact with the slide rail 12. During operation, the roller 14 moves on the slide rail 12, which reduces the resistance of the cable guide screw 4 driving the cable guide bracket 5 to move. The cable guide wheel mechanism 10 includes a first top plate 101; the first top plate 101 is fixedly connected to the external bracket; the first top plate 101 is horizontally arranged; a fixing plate is fixedly connected to the first top plate 101; the upper end of the fixing plate is fixedly connected to the first top plate 101; the fixing plate is vertically arranged; the lower end of the fixing plate is fixedly connected to a horizontal plate 102; the horizontal plate 102 is parallel to the first top plate 101; a guide wheel screw 103 is threadedly connected to the horizontal plate 102; the guide wheel screw 103 is located at... On one side of the fixed plate; a first movable plate 104 is threadedly connected to the guide wheel screw 103; the upper end of the guide wheel screw 103 is threadedly connected to the horizontal plate 102; the lower end of the guide wheel screw 103 is threadedly connected to the first movable plate 104; a second movable plate 105 is fixedly connected to the first movable plate 104; the second movable plate 105 and the fixed plate are arranged parallel to each other, and the second movable plate 105 and the fixed plate are located on the same side of the first movable plate 104; two guide wheels 106 are rotatably connected to the second movable plate 105; The cable laying guide wheel mechanism 10 is fixed to the first top plate 101 by an external support frame; the height of the guide wheel 106 can be adjusted by manually rotating the guide wheel screw 103, which can adapt to cable laying and cable feeding mechanisms of different heights. The guide wheel 106 includes a fixed baffle 1061; the fixed baffle 1061 is rotatably connected to the second movable plate 105, and an adjusting screw 1062 is fixedly connected to the middle of the fixed baffle 1061; a movable baffle 1063 is threadedly connected to the adjusting screw 1062. The distance between the movable baffle 1063 and the fixed baffle 1061 can be adjusted according to the different diameters of the cables by moving the movable baffle 1063 on the adjusting screw 1062. A base 107 is fixedly connected to the base 1; a second top plate 108 is fixedly connected to the upper end of the base 107; the second top plate 108 is horizontally arranged; a third motor 109 is fixedly connected to the second top plate 108; a guide wheel screw 103 is fixedly connected to the output end of the third motor 109; a first moving plate 104 is threadedly connected to the guide wheel screw 103; the first moving plate 104 is horizontally arranged; a second moving plate 105 is fixedly connected to the first moving plate 104; the second moving plate 105 is vertically arranged, and two guide wheels 106 are rotatably connected to the second moving plate 105. The third motor 109 is controlled by the PLC controller so that the guide wheel screw 103 can control the height of the guide wheel 106. The wire feeding mechanism 11 includes a wire feeding bracket; the wire feeding bracket is fixedly connected to the base 1; the wire feeding bracket is located on the right side of the wire guide wheel mechanism 10; a fourth motor 111 is fixedly connected to one side of the wire feeding bracket; and a wire feeding reel is fixedly connected to the output end of the fourth motor 111. During operation, after the proximity switch sensor 9 sends an electrical signal to the PLC controller, the PLC controller controls the rotation speed of the fourth motor 111 and the servo motor 3, so that the length of the cable released by the cable feeding mechanism 11 in the same time period is basically the same as the length of the cable in the cable tray 7; so that the cable on the cable tray is subjected to uniform tension and the cable on the cable tray 7 is evenly distributed. Working principle: During operation, the cable from the cable feeding mechanism 11 passes through the cable guide wheel mechanism 10 and winds onto the cable support 5. The servo motor 3 is activated; its output drives the cable guide screw 4 to rotate, causing the cable support 5 to move. The cable released from the cable feeding mechanism 11 passes sequentially through the cable guide wheel mechanism 10 and the limiting component 8 onto the moving cable reel 7. The time it takes for the cable reel 7 to rotate once is equal to the diameter distance the cable moves on the cable guide screw 4, preventing the cable from being pulled by the movement of the cable support 5. When the cable support 5 moves close to one of the first supports 2, the proximity switch sensor 9 of that first support 2 senses the cable support 5 and sends an electrical signal to the PLC controller. The servo motor 3 changes its rotation direction, causing the cable guide screw 4 to rotate in the opposite direction, thus moving the cable guide bracket 5 in the opposite direction. The PLC controller, while controlling the servo motor 3, also controls the rotation speed of the servo motor 3 and the fourth motor 111 based on the cable diameter. This ensures that the cable length released by the cable feeding mechanism 11 is approximately the same as the cable length on the cable guide reel 7 within the same time period, resulting in uniform tension on the cable on the cable guide reel 7 and uniform cable arrangement. During operation, the cable is passed between the two limit brackets 81 and wound onto the cable guide reel 7. The distance between the two limit brackets 81 is controlled by bolts 88, allowing the two limit brackets 81 to be adjusted according to the cable diameter. This enables the limit plate 84 to more precisely limit the cable movement. When the cable guide bracket 5 opens... When the cable tray 5 initially moves to the left (first support 2), the left electromagnet 85 is energized, causing the left iron plate 86 to be attracted to the electromagnet 85 by magnetic force. This compresses the left spring 85, preventing the left limit plate 84 from contacting the cable tray. The right electromagnet 85 is de-energized, and the top of the right limit plate contacts the cable tray. When the proximity switch sends an electrical signal, the PLC controller de-energizes the left electromagnet 85, causing the left limit plate 84 to move upwards due to the spring's elasticity and contact the previously arranged cable. Simultaneously, the PLC controller energizes the right electromagnet 85, causing the right limit plate 84 to move downwards due to magnetic force. By alternately energizing the two electromagnets 85, the two limit plates 84 move in different directions. The cable guide mechanism 10 is designed to limit cable movement and make cable routing neater. A slide rail 12 is provided on the base 1, located between the two first supports 2. Several roller grooves 13 are provided on the cable routing support 5. Rollers 14, which are rotatably connected to the roller grooves 13 and slide in contact with the slide rail 12, are also provided. The cable routing guide mechanism 10 is fixed to the first top plate 101 via an external support frame. The height of the guide wheel 106 can be adjusted by manually rotating the guide wheel screw 103, accommodating cable routing mechanisms of different heights. The distance between the movable baffle 1063 and the fixed baffle 1061 can be adjusted according to the cable diameter by moving the movable baffle 1063 on the adjusting screw 1062.
