Technical Field
[0001] This utility model relates to the technical field of wire laying equipment, and in particular to a multi-axis gravity wire laying frame device. Background Technology
[0002] Chinese utility model patent with patent number ZL202222858435.2 and patent name: A wire feeding frame, specifically discloses the following technical solution: A wire feeding frame includes a frame, a speed control box mounted on the frame, a wire storage rack mounted at one end of the frame, and five mounting plates fixedly mounted on both sides of the frame, the five mounting plates forming a group, and a set of wire feeding components mounted on each mounting plate; the wire feeding component includes a reduction motor composed of a worm gear transmission assembly and a wire feeding drive motor, and a wire feeding drum driven by the reduction motor; the wire storage rack includes a carrier plate mounted on the frame, and five pre-storage racks are vertically fixedly mounted on the carrier plate at equal intervals from left to right, each pre-storage rack... A sensor is installed near the top and bottom of the storage rack, and each sensor is electrically connected to the speed control chassis. The pre-storage rack includes a main rack and a secondary rack arranged opposite each other. The bottom ends of the main rack and the secondary rack are positioned and fixed by a connecting end block, which is fixedly connected to the carrier plate. Two parallel sliders are slidably installed in the gap between the main rack and the secondary rack. A first guide wheel is rotatably installed on the middle of the outer side of each slider. The top ends of the main rack and the secondary rack are positioned and fixed by a positioning block and bolts. One end of the positioning block is fixedly connected to one side of the top of the frame, and two second guide wheels are rotatably installed on both sides of the positioning block. A cable shaping assembly is installed on the top of the frame.
[0003] During the operation of the aforementioned wire feeding frame, as the wire tip is continuously fed, the wire will pull the slider upward. When the sensor located above the pre-storage frame detects the slider, the speed control box controls the wire feeding drive motor to work, driving the wire feeding drum to rotate (loosening the fixing of the wire tail end) and performing the wire feeding operation. At this time, the slider will slide downward under the action of gravity. During the downward sliding process of the slider, the wire can always be kept taut. When the sensor located below the pre-storage frame detects the slider, the speed control box controls the wire feeding drive motor to stop working. At this time, the pre-storage frame completes the wire pre-storage.
[0004] It should be noted that the aforementioned wire feeding frame still has the following defects, specifically: Defect 1: For the pre-storage rack, the overall weight of the assembly structure consisting of the slider and the first guide wheel determines the tension of the corresponding wire during the wire feeding process; for the pre-storage rack of the above-mentioned wire feeding rack, it cannot adaptively adjust the tension according to the thickness of the wire and the tension requirements, and the adjustability is poor. Defect 2: The wire feeding rack does not have a missing wire detection function. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-axis gravity wire feeding device to address the shortcomings of the existing technology. This multi-axis gravity wire feeding device has a novel structural design, strong adjustability, and can realize the missing wire sensing function.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0007] A multi-axis gravity wire feeding device includes a frame, a controller, a wire storage rack assembly, and a straightener assembly. Several wire feeding components are arranged at intervals on the left and right sides of the frame. The wire storage rack assembly includes several wire storage racks arranged sequentially from left to right. The straightener assembly includes several straighteners arranged sequentially from left to right. The wire fed out by each wire feeding component passes through the corresponding wire storage rack and straightener in sequence and is fed forward. The wire storage rack includes a vertical trough rack mounted on the frame and arranged vertically. A fixed guide wheel is rotatably mounted on the upper end of the vertical trough rack. A lifting slider located below the fixed guide wheel is slidably mounted on the vertical trough rack. The lifting slider is rotatably mounted with a lifting guide wheel. Each lifting slider has a hanging slot at its lower end, and each wire storage rack is equipped with a counterweight. Each counterweight is equipped with a hanging rod, and the hanging rod of each counterweight is suspended in the hanging slot of the corresponding lifting slider. Each vertical trough is equipped with a missing wire sensing component on the upper end of the corresponding wire conveying path. The missing wire sensing component includes a wire-passing block that is fastened to the upper end of the corresponding vertical trough. The wire-passing block has a wire-passing through hole for the wire to pass through. The wire-passing block has a vertical through hole. A movable sensing plate is slidably installed in the vertical through hole. The upper end of the movable sensing plate has a sensing plate through hole for the wire to pass through. A missing wire sensor is installed at the lower end of the fixed block, located directly below the vertical through hole. The missing wire sensor is electrically connected to the controller. When a wire passes through the through-hole of the movable sensing element, the movable sensing element hangs on the wire and moves away from the missing wire sensor; when no wire passes through the through-hole of the movable sensing element, the movable sensing element moves down along the vertical through-hole to the lower limit position and triggers the missing wire sensor.
[0008] The missing wire sensor is a slotted photoelectric sensor. When no wire passes through the through hole of the movable sensing piece, the lower end of the movable sensing piece falls into the sensing slot of the slotted photoelectric sensor, and the lower end of the movable sensing piece abuts against and is limited to the slotted photoelectric sensor.
[0009] The wire feeding assembly includes a geared motor that is fastened to the frame. The power output shaft of the geared motor is connected to a wire spool placement shaft. The geared motor is electrically connected to the controller.
[0010] The multi-axis gravity pay-off frame device also includes a protective frame, and the frame is mounted on the protective frame; The left and right sides of the protective frame are respectively equipped with bottom double doors and an upward-opening door above the bottom double doors. Each double door and each upward-opening door is installed on the protective frame by hinges.
[0011] The bottom of the protective frame is equipped with several casters arranged at intervals.
[0012] Compared with the prior art, the present invention has the following beneficial effects, specifically: 1. After the wire feeding assembly has finished feeding the wire, this utility model can sense the completion of wire feeding through the wire shortage sensing component to realize the automatic wire shortage sensing function; 2. During the process of the wire passing through the wire storage rack, the staff can select a counterweight of appropriate weight to hang on the lifting slider according to the thickness of the wire and the required wire tension. By controlling the weight of the counterweight, the tension of the wire can be adjusted, thereby achieving wire tension regulation. 3. Therefore, the multi-axis gravity wire feeding frame device of this utility model has the advantages of novel structural design and strong adjustability, and can realize the missing wire sensing function.

Detailed Implementation
[0021] The present invention will now be described in conjunction with specific embodiments.
[0022] Example 1, as Figures 1 to 4 As shown, a multi-axis gravity wire feeding device includes a frame 1. The frame 1 is equipped with a controller 2, a wire storage rack assembly 3, and a straightener assembly 4. Several wire feeding components 5 are arranged at intervals on the left and right sides of the frame 1. The wire storage rack assembly 3 includes several wire storage racks 31 arranged sequentially from left to right. The straightener assembly 4 includes several straighteners arranged sequentially from left to right. The wires fed out by each wire feeding component 5 pass through the corresponding wire storage rack 31 and straightener in sequence and are fed forward.
[0023] Among them, such as Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the wire storage rack 31 includes a vertical trough rack 311 mounted on the frame 1 and arranged vertically. A fixed guide wheel 312 is rotatably mounted on the upper end of the vertical trough rack 311. A lifting slider 313 located below the fixed guide wheel 312 is slidably mounted on the vertical trough rack 311. A lifting guide wheel 314 is rotatably mounted on the lifting slider 313.
[0024] Furthermore, such as Figure 5 As shown, each lifting slider 313 has a hanging groove 3131 at its lower end, and each wire storage rack 31 is equipped with a counterweight 315. Each counterweight 315 is provided with a hanging rod 3151, and the hanging rod 3151 of each counterweight 315 is suspended in the hanging groove 3131 of the corresponding lifting slider 313. Furthermore, such as Figure 5As shown, each vertical tray 311 has a missing wire sensing component 6 installed at its upper end on the corresponding wire conveying path. The missing wire sensing component 6 includes a wire-passing block 61 that is fastened to the upper end of the corresponding vertical tray 311. The wire-passing block 61 has a wire-passing through hole 611 for the wire to pass through, and a vertical through hole 612 that passes through vertically. A movable sensing plate 62 is slidably installed in the vertical through hole 612. The upper end of the movable sensing plate 62 has a sensing plate through hole 621 for the wire to pass through. A missing wire sensor 63 located directly below the vertical through hole 612 is installed at the lower end of the fixed block. The missing wire sensor 63 is electrically connected to the controller 2.
[0025] It needs to be explained that, such as Figure 6 As shown, the wire feeding assembly 5 in this embodiment includes a geared motor 51 that is fastened to the frame 1. The power output shaft of the geared motor 51 is connected to a wire spool placement shaft 52. The geared motor 51 is electrically connected to the controller 2.
[0026] It should be noted that when a wire passes through the sensing hole 621 of the movable sensing piece 62, the movable sensing piece 62 is suspended on the wire and is far away from the wire shortage sensor 63; when no wire passes through the sensing hole 621 of the movable sensing piece 62, the movable sensing piece 62 moves down along the vertical through hole 612 to the lower limit position, and the movable sensing piece 62 triggers the wire shortage sensor 63. Therefore, after the wire delivery assembly 5 has delivered all the wire on the spool, this embodiment can sense the completion of wire delivery through the wire shortage sensing assembly 6, and the wire shortage sensing assembly 6 can feed back the wire shortage signal to the controller 2, and the controller 2 triggers a wire shortage alarm.
[0027] It should be emphasized that, for the wire storage rack 31 in this embodiment, during the process of the wire passing through the wire storage rack 31, the operator can select a counterweight 315 of appropriate weight to hang on the lifting slider 313 according to the thickness of the wire and the tension requirements of the wire release. By controlling the weight of the counterweight 315, the tension of the wire can be adjusted, thereby realizing the adjustment of the wire release tension.
[0028] In summary, through the above structural design, the multi-axis gravity wire feeding frame device of this embodiment has the advantages of novel structural design and strong adjustability, and can realize the missing wire sensing function.
[0029] Example 2 differs from Example 1 in that the missing wire sensor 63 is a slot-type photoelectric sensor. When no wire passes through the sensing plate through hole 621 of the movable sensing plate 62, the lower end of the movable sensing plate 62 falls into the sensing slot of the slot-type photoelectric sensor, and the lower end of the movable sensing plate 62 abuts against and is limited to the slot-type photoelectric sensor.
[0030] Example 3, as Figures 1 to 4As shown, the difference between this embodiment three and embodiment one is that the multi-axis gravity pay-off frame device also includes a protective frame 7, and the frame 1 is installed on the protective frame 7; The left and right sides of the protective frame 7 are respectively equipped with a bottom double door 71 and an upward-opening door 72 located above the bottom double door 71. Each double door and each upward-opening door 72 are installed on the protective frame 7 by hinges.
[0031] It should be explained that the bottom double door 71 and the top-opening door 72 in this embodiment can be transparent acrylic door structures.
[0032] In addition, the bottom double door 71 and the top-opening door 72 of this embodiment can serve as both external protection for the cable tray and facilitate cable replacement and threading.
[0033] Example 4, as Figure 3 and Figure 4 As shown, the difference between this embodiment four and embodiment three is that the bottom of the protective frame 7 is equipped with several casters 8 arranged at intervals.
[0034] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
