Description

Technical Field

[0001] This invention relates to the field of cord winding machine technology, specifically a cord winding machine with a concealed cable routing design and a dual-station take-up device. Background Technology

[0002] Steel cord is the skeleton material used in radial tires. It is made of multiple steel wires or strands twisted together. A cord winding machine is a device that twists multiple ultra-fine metal wires into ropes according to a set twist pitch to obtain the finished steel cord. The main structure of a cord winding machine includes a pay-off section, a main machine section, and a take-up section. The pay-off section mainly consists of a pay-off bracket for holding the I-beams to pay off the metal wires. The main machine section usually has a cradle, and the internal flywheel rings rotate to twist the steel wires into ropes. After the steel cord is twisted in the take-up section, it finally passes through the winding mechanism in the take-up section, where the steel cord is neatly and orderly arranged on the take-up I-beams.

[0003] Typically, once the coil is fully wound, it needs to be manually unloaded and reloaded to continue winding. Currently, the winding process on steel cord production machines is mostly done manually. However, with the development of automation, combining steel cord machines with intelligent manufacturing and promoting automated loading and unloading by robotic arms has gradually become a trend.

[0004] In the process of promoting the automatic loading and unloading of robotic arms, it is usually necessary to set up robotic arms outside the original manual operation area to realize the automatic loading and unloading of robotic arms. This will result in no space suitable for manual operation. Once the robotic arm malfunctions, it will require manual operation by employees. Employees standing on the robotic arm operation surface to operate it pose safety hazards. If manual operation is not possible, the machine will not be able to produce continuously, and the utilization rate of the machine will decrease. Summary of the Invention

[0005] This invention provides a cord winding machine with a concealed cable routing design and a dual-station take-up device. By redesigning the take-up section structure and using a concealed cable routing design, it provides separate workstations for a robotic arm and a manual operation station. When the robotic arm is under maintenance, or during manual operation, there are no potential safety hazards to the employees.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0010] Furthermore, a limit frame is installed on the base plate, the take-up swing rod is disposed inside the limit frame, and a rubber shock-absorbing pad is provided at each of the upper and lower ends of the limit frame facing the take-up swing rod. A limit switch is fixedly connected to the base plate above the take-up swing rod.

[0011] Furthermore, it also includes guide wheels A and B connected by guide wheel connecting rods to the cable laying mechanism and the swing arm device. The guide wheel A is fixedly connected to the mounting plate A. One end of the mounting plate is fixedly rotated in the fixing block A on the base plate through a pin A and a bearing. The guide wheel B is installed on the mounting plate B. One end of the mounting plate B is rotatably connected to the cable laying mechanism through a pin B and a bearing. A guide wheel connecting rod is also provided.

[0015] Furthermore, an operation panel is provided on the upper part of the workbench, and the operation panel is rotatably connected to the workbench.

[0016] The present invention has the following beneficial effects:

[0017] By setting up a sorting section between the main unit and the take-up section, the sorting section provides space for workers to operate, forming a situation where the robotic arm's workstation is located on the outside of the workbench, while the manual workstation is located between the main unit and the take-up section. At the same time, the swing arm device and the cable laying mechanism are redesigned to meet the requirements of dual-station operation, enabling manual operation when the robotic arm malfunctions, and avoiding the safety hazards caused by the robotic arm and manual workstation being located on one side.

[0025] Furthermore, the swing arm device 4021 includes a base plate 40211, a fixed rod 40212, a take-up swing arm 40213, and a tension spring 40214. The lower end of the fixed rod 40212 is fixed to the upper end of the base plate 40211 and connected to the take-up swing arm 40213 through the tension spring 40214. One end of the take-up swing arm 40213 is rotatably connected to the base plate 40211, and the other end is provided with a guide wheel 402131.

[0026] Furthermore, in order to monitor the swing amplitude of the take-up lever 40213, one end of the take-up lever 40213 is fixedly connected to the center of the eccentric wheel 40215. The eccentric wheel 40215 is rotatably connected to the base plate 40211. A photoelectric switch 40217 is installed directly above the eccentric wheel 40215. The photoelectric switch 40217 is fixed to the base plate 40211 by a mounting plate 40216.

[0027] Furthermore, in order to limit the position of the take-up swing arm 40213, a limit frame 40218 is installed on the base plate 40211, and the take-up swing arm 40213 is disposed inside the limit frame 40218. Each of the upper and lower ends of the limit frame 40218 is provided with a rubber shock-absorbing pad 402181 facing the take-up swing arm 40213, thereby preventing the take-up swing arm 40213 from impacting and damaging the limit frame 40218. A limit switch 40219 is fixedly connected to the base plate 40211 above the take-up swing arm 40213, so as to stop the swing arm in time when the swing amplitude is too large.

[0028] Furthermore, in order to guide the steel cord from the swing arm device into the cable laying device, this device also includes guide wheels A304 and B305 connected to the cable laying mechanism 303 and the swing arm device 4021 via a guide wheel connecting rod 307. The guide wheel A304 is fixedly connected to the mounting plate A3041. One end of the mounting plate A3041 is fixedly rotated within the fixing block A30412 on the base plate 40211 via a pin A30411 and a bearing. The guide wheel B305 is mounted on the mounting plate B3051. One end of the mounting plate B3051 is rotatably connected to the cable laying mechanism 303 via a pin B30511 and a bearing. A guide wheel connecting rod 307 is also provided. The lower end of the guide wheel connecting rod 307 is fixed to the sleeve on the back of the mounting plate B3051, and the upper end passes through the sleeve on the back of the mounting plate A3041.

[0029] Furthermore, to ensure that the cable laying mechanism 303 does not interfere with manual operation, the cable laying mechanism 303 includes a guide wheel mounting plate 3031, a slider connecting plate 3032, a synchronous motor 3033, a frame 3034, a guide rod 3035, and a synchronous belt 3036. The guide wheel mounting plate 3031 is fixedly connected to the slider connecting plate 3032, the slider connecting plate 3032 is slidably connected to the guide rod 3035, and the synchronous motor 3033 is fixedly connected to the frame 3034 and drivenly connected to the synchronous belt 3036. The lower part of the slider connecting plate 3032 is pressed and connected to the synchronous belt 3036 by a screw plate. A position sensor is also provided. The position sensor is fixedly installed on the optical axis on the back of the frame 3034 by a position sensor bracket 3037. The mounting plate B3051 is rotatably connected to the slider connecting plate 3032. The upper part of the slider connecting plate 3032 is provided with the strip groove 3011. A transition wheel group B30321 is installed on the upper part of the slider connecting plate 3032 for guiding the steel cord into the take-up device 302.

[0030] Furthermore, in order to facilitate the introduction of the steel cord from the main unit 20 into the sorting unit 40, a transition wheel set C4011 is also provided on the upright A401 for guiding the steel cord from the main unit 20 into the torsion controller 405.

[0031] Furthermore, the take-up device 302 includes a take-up shaft bearing seat 3022, which is disposed on the worktable 301 for clamping the I-beam reel for take-up. The take-up shaft bearing seat 3022 is configured with a pin-shaped plastic disc.

[0032] Furthermore, to further facilitate manual operation, an operation panel 308 is also provided on the upper part of the workbench 301, and the operation panel 308 is rotatably connected to the workbench 301.

[0033] Specifically

[0034] like Figure 3 As shown, the base plate 40211 is fixed to the upright frame B402. The lower end of the fixing rod 40212 is fixedly connected to the base plate 40211, and its upper end is connected to the take-up swing rod 40213 through a tension spring 40214. One end of the take-up swing rod 40213 is fixed to the center of the eccentric wheel 40215. The eccentric wheel 40215 is rotatably connected to the base plate 40211. A photoelectric switch 40217 is installed directly above the eccentric wheel 40215. The photoelectric switch 40217 is fixed to the base plate 40211 through a mounting plate 40216. When the take-up speed is too fast or too slow, causing the take-up swing rod 40213 to rotate upward or downward, the photoelectric switch 40217 detects the eccentric wheel 40215. The position of the take-up lever 40213 is fed back to the take-up motor to control the take-up speed. At the same time, the swing amplitude of the take-up lever 40213 can provide feedback on whether the wire arrangement is stable. In order to better control the swing amplitude of the take-up lever 40213, a limit frame 40218 is also installed on the base plate 40211. The limit frame 40218 is fixed on the base plate 40211, and the take-up lever 40213 is set inside the limit frame 40218. There is a rubber shock-absorbing pad 402181 at the upper and lower ends of the limit frame 40218. At the same time, a limit switch 40219 is fixedly connected to the base plate 40211 above the take-up lever 40213. When the take-up lever 40213 touches the limit switch 40219, the machine stops.

[0035] like Figure 4As shown, the main structures are the take-up section 30 and the upright frame B402. The wire winding mechanism 303 is installed below the workbench 301. The wire is led out from the guide wheel of the take-up lever 40213, passes through guide wheels A304 and B305, and finally winds onto the I-beam reel via guide wheel C306. Guide wheel A304 is mounted on mounting plate A3041. One end of mounting plate A3041 is fixed to the fixing block A30412 on the base plate 40211 via pin A30411 and a bearing. Mounting plate A3041 is welded to pin A30411, allowing mounting plate A3041 to move along... The axis of the pin A30411 rotates, and the guide wheel B305, which is also located above the wire laying mechanism 30, is installed on the mounting plate B3051. The mounting plate B3051 is welded and fixed to the pin B30511, and is installed in the fixing block B30512 through the bearing, so that the mounting plate B3051 can rotate along the axis of the pin B30511. The lower end of the guide wheel connecting rod 307 is fixed to the sleeve on the back of the mounting plate B3051, and the upper end passes through the sleeve on the back of the mounting plate A3041. As the position of the mounting plate B3051 moves, it drives the mounting plate A3041 to swing, thereby realizing the wire laying with the movement of the wire laying mechanism 303.

[0036] like Figure 5 As shown, in the cable laying mechanism 303, the guide wheel mounting plate 3031 is fixed on the slider connecting plate 3032, the synchronous motor 3033 is fixed on the frame 3034 of the cable laying mechanism 303, the lower end of the slider connecting plate 3032 passes through the strip groove 3011 on the worktable 301 and is slidably connected to the guide rod 3035 of the cable laying mechanism 303, the synchronous belt 3036 is pressed and connected to the slider connecting plate 3032 by screws and pressure plates, so that the slider connecting plate 3032 and the synchronous belt 3036 move together, and the position sensor bracket 3037 is fixed on the optical axis on the back of the frame 3034, and can be adjusted and fixed along the optical axis to adjust the cable laying stroke.

[0037] like Figure 4 As shown, the take-up shaft bearing seat 3022 of the take-up device 302 is mounted on the worktable 301. Due to the concealed design of the wire laying mechanism 303 and the spatial arrangement of the connecting rod 403, the robot arm operating surface and the manual operating surface are located on both sides of the take-up device 302, respectively. The I-beam is placed on the take-up shaft of the take-up device 302. During the take-up operation, the wire laying guide wheel reciprocates according to the set wire laying stroke, and the steel cord is evenly distributed on the I-beam. At the same time, the operation panel 308 on the worktable 301 is rotatable, which facilitates rotation for manual operation.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
