Description

Technical Field

[0001] The present application relates to the technical field of material feeding, and in particular to a precise material feeding device for coiled materials. Background Art

[0002] During production and processing, coils need to be cut into appropriate lengths according to process requirements. Coils are generally rolled up and stored on reels, which are driven by motors to rotate and transport the unrolled coils to the process system.

[0003] In the related art, a motor is generally used to directly drive the reel 100 to rotate so as to achieve material feeding. However, in actual work, when the end of the coil 200 is not fixed to the reel, the motor driving the reel 100 to rotate may cause the reel 100 to rotate idly, resulting in the defect that the discharge of the coil 200 cannot be accurately controlled. Summary of the invention

[0004] In order to achieve accurate feeding, the present application provides a precise feeding device for coiled materials.

[0005] The present application provides a precise feeding device for coiled materials using the following technical solution:

[0006] A precise feeding device for coiled materials comprises a frame, on which a coil rotates in a horizontal direction, an active roller is rotatably arranged on the frame, the active roller is arranged horizontally, a driving component for driving the active roller to rotate is arranged on the frame, a passive roller is also arranged on the upper side of the active roller, the passive roller rotates on the frame in a direction parallel to the rotation direction of the active roller, a material passing gap for the coil to pass through is formed between the passive roller and the active roller, a balancing roller for pressing the discharge end of the coil is also arranged on the frame, the balancing roller is arranged horizontally, the axial direction of the balancing roller is parallel to the axial direction of the coil, and a monitoring component for monitoring the rotation of the balancing roller is also arranged on the frame.

[0007] By adopting the above technical solution, in actual work, the staff will set up the reel on the frame, pass the discharge end of the coil through the gap between the active roller and the passive roller, the active roller and the passive roller clamp the coil, and the discharge end of the coil then passes through the frame from the upper or lower side of the balance roller, and the outer side of the balance roller is pressed against the coil. When it is necessary to discharge the material, the drive component drives the active roller to rotate outward, thereby pulling the coil forward, driving the passive roller and the balance roller to rotate, so as to achieve precise feeding. The staff can detect whether the feeding device is feeding through the monitoring component. The feeding device set up in this way helps to reduce the occurrence of unsuccessful feeding caused by the idle rotation of the reel. The coil is pressed on the outer side of the active roller through the passive roller. Through the friction between the active roller and the coil, it is ensured that the rotation of the motor will definitely drive the coil forward, so as to achieve precise feeding.

[0008] Preferably, the passive roller is arranged on the frame to slide along the vertical direction, and the frame is provided with a pushing component for pushing the passive roller to slide.

[0009] By adopting the above technical solution, the staff can push the passive roller to slide down in the vertical direction by pushing the assembly. In this way, the size of the material gap between the passive roller and the active roller can be changed, so that the device can be applied to coils of different thicknesses, which helps to improve the practicality of the device. After the coil passes through the material gap between the passive roller and the active roller, the friction between the coil and the active roller is changed by changing the spacing between the passive roller and the coil, thereby changing the relative speed of the coil. In this way, it is convenient for the staff to fine-tune the feeding speed of the device.

[0010] Preferably, a PLC controller is also provided on the frame, and the PLC controller controls the driving component to drive the active roller to rotate, and the PLC controller also controls the pushing component to push the passive roller to slide downward in the vertical direction.

[0011] By adopting the above technical solution, in actual work, the staff can control the driving component and the pushing component through the PLC controller, which helps to improve the automation level of the feeding device.

[0012] Preferably, the pushing component includes a pushing cylinder, the cylinder body of the pushing cylinder is vertically arranged, a fixed block is fixed to the end of the pushing cylinder push rod away from the cylinder body, the passive roller is rotatably connected to the fixed block, and the pushing cylinder and the fixed block are each arranged at both ends of the passive roller.

[0013] By adopting the above technical solution, the relative position between the passive roller and the active roller is controlled by controlling the two pushing cylinders.

A reflective strip corresponding to the photoelectric speed sensor is affixed to the balancing roller, and the photoelectric speed sensor is connected to a PLC controller signal.

[0015] By adopting the above technical solution, when the coil is discharged, the discharge end of the coil is pressed against the outer surface of the balance roller, thereby driving the balance roller to rotate. By monitoring the rotation speed of the balance roller, the amount of coil discharged can be monitored. The PLC controller compares the detected rotation speed of the balance roller with the preset discharge speed, and then controls the drive component and the push component through the PLC controller to change the discharge speed. In this way, it helps to further improve the automation level of the device.

[0016] Preferably, a transition roller is rotatably arranged on the frame, the transition roller is arranged horizontally, the transition roller is located on the upper side of the balancing roller, and the coil is sequentially attached to the outer sides of the transition roller and the balancing roller.

[0017] By adopting the above technical solution, the curved coil can be made flat through the transition roller and the balance roller, and it helps to prevent the discharge speed from being too fast.

[0018] Preferably, a support assembly for supporting the rotating coil is also provided on the frame.

[0019] By adopting the above technical solution, the support assembly helps to ensure the stability of the rotating coil on the frame.

[0020] Preferably, the support assembly includes rollers, which are horizontally arranged, and both ends of the rollers are rotatably connected to the frame respectively, and the rollers are located at the lower side of the drum, and one roller is arranged on each side of the drum in the horizontal direction.

[0021] By adopting the above technical solution, the coil is pulled out from the reel, driving the lower roller to rotate. The roller can provide vertical upward support force for the coil on the reel, thereby helping to ensure the stability of the reel on the frame.

[0022] Preferably, the frame is also provided with a coil limiting assembly for limiting the relative position of the coil in the axial direction of the reel and a reel limiting assembly for limiting the relative position of the reel on the frame.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a precise feeding device for coiled materials.

[0037] See also Figure 1 The reel 100 is arranged horizontally, and the coil 200 is wound on the reel 100 .

[0038] See also Figure 1-Figure 4The precise feeding device for coiled materials comprises a frame 1, wherein the length direction of the frame 1 is parallel to the length direction of the reel 100. A support assembly 3 is arranged on the frame 1, and the support assembly 3 comprises a roller 31, wherein the roller 31 is arranged horizontally, and the axis direction of the roller 31 is parallel to the length direction of the frame 1. Both sides of the axis direction of the roller 31 are rotatably connected to the frame 1. The roller 31 is arranged on the lower side of the reel 100, and one roller 31 is arranged on each side of the reel 100 along its own horizontal radial direction. When the coil 200 rotates, the coil 200 drives the two rollers 31 to rotate around their own axis directions respectively. The roller 31 can provide a vertical upward support force to the coil 200 on the reel 100, so that the device can be applied to the coil 200 with a larger mass, and at the same time, the stability of the reel 100 on the frame 1 can be ensured.

[0039] The frame 1 is also provided with a reel limiting assembly 4, which includes a vertically arranged slide bar 41, which is arranged at a section in the axial direction of the reel 100, and is fixedly connected to the frame 1. A slider 42 is arranged on the slide bar 41, and the slider 42 and the slide bar 41 slide and cooperate in the vertical direction. A positioning plate 43 is fixed on the slider 42, and the thickness direction of the positioning plate 43 is parallel to the axial direction of the reel 100. A U-shaped groove 431 is provided on the positioning plate 43, and the U-shaped groove 431 penetrates the positioning plate 43 in the thickness direction of the positioning plate 43, and the lower side of the U-shaped groove 431 is open. The two rollers 31 are symmetrically arranged along the vertical plane of the axis passing through the U-shaped groove 431. The reel 100 is inserted in the U-shaped groove 431. The reel limiting assembly 4 is provided with one at each end in the axial direction of the reel 100. The staff pushes the slider 42 to the top, places the reel 100 between the two rollers 31, and releases the slider 42. The slider 42 slides downward under the action of gravity, and the inner side walls of the two U-shaped grooves 431 respectively abut against the outer side walls at both ends of the axis direction of the reel 100. In this way, it helps to ensure the stability of the reel 100 on the frame 1 and helps to reduce the possibility of the reel 100 jumping around due to the coil 200 rotating too fast.

[0040] The frame 1 is also provided with a coil limiting assembly 5. The coil limiting assembly 5 includes a horizontally arranged slide rail 51, which is fixedly connected to the frame 1. An abutment plate 52 is arranged on the slide rail 51, which is vertically arranged, and the thickness direction of the abutment plate 52 is parallel to the length direction of the frame 1. The abutment plate 52 is located between the two rollers 31, and the abutment plate 52 slides with the slide rail 51 in the length direction of the frame 1. The coil limiting assembly 5 is provided with one at each end of the axis direction of the reel 100. After the staff places the reel 100 with the coil 200 wound on the two rollers 31, the position of the reel 100 is adjusted, thereby adjusting the discharge end of the coil 200, and pushing the abutment plates 52 on both sides to slide along the slide rail 51, so that the abutment plates 52 on both sides are respectively pressed against the sides of the coil 200. In this way, it helps to reduce the possibility of the coil 200 moving in the horizontal direction during the rotation process to affect the feeding effect.

[0041] The frame 1 is provided with an active roller 6, which is arranged horizontally, and the axial direction of the active roller 6 is parallel to the length direction of the frame 1. Both ends of the axial direction of the active roller 6 are rotatably connected to the frame 1. A driving component 61 is also provided at one end of the axial direction of the active roller 6, and the driving component 61 is a driving motor 611, and the output shaft of the driving motor 611 is coaxially fixed with the active roller 6. The frame 1 is provided with an equipment box 2, and the driving motor 611 is arranged in the equipment box 2, and the output shaft of the driving motor 611 passes through the equipment box 2. A PLC controller is also provided in the equipment box 2. The driving motor 611 is electrically connected to the PLC controller.

[0042] A passive roller 7 is arranged on the upper side of the active roller 6, and the axis direction of the passive roller 7 is parallel to the axis direction of the active roller 6. The passive roller 7 is arranged at a distance from the active roller 6, and a feeding gap is formed. The staff passes the discharge end of the coil 200 through the feeding gap, and the lower side of the outer side of the passive roller 7 is pressed against the coil 200, and the lower side of the coil 200 is also attached to the upper side of the outer side of the active roller 6. When feeding is required, the staff controls the drive motor 611 to start through the PLC controller, and the drive motor 611 rotates to drive the active roller 6 to rotate, and the passive roller 7 presses the coil 200 on the outer side of the active roller 6, and the coil 200 rotates with the active roller 6 under the action of friction, thereby achieving accurate feeding.

[0043] The frame 1 is provided with a pushing assembly 71, which includes a pushing cylinder 711. The piston rod of the pushing cylinder 711 slides and cooperates with its cylinder body in the vertical direction, and the cylinder body of the pushing cylinder 711 is fixed on the frame 1. The pushing cylinder 711 is electrically connected to the PLC controller. A fixed block 712 is fixed to the end of the piston rod of the pushing cylinder 711 away from its cylinder body, and the fixed block 712 is rotatably connected to one end of the passive roller 7 in the axial direction. The pushing assembly 71 is provided with one at each end in the axial direction of the passive roller 7. The staff controls the relative position of the piston rod of the pushing cylinder 711 in its cylinder body through the PLC controller, thereby controlling the size of the material gap between the passive roller 7 and the active roller 6, so that the device is suitable for coils 200 of different thicknesses, which helps to improve the practicality of the feeding device. After the coil 200 passes through the gap between the passive roller 7 and the active roller 6, the cylinder 711 is pushed to change the distance between the passive roller 7 and the coil 200, and the friction between the coil 200 and the active roller 6 is adjusted, thereby changing the relative speed of the coil 200, making it convenient for the staff to fine-tune the feeding speed of the device.

[0044] See also Figure 1-Figure 5 , a transition roller 8 is horizontally arranged on the frame 1, the axis direction of the transition roller 8 is parallel to the axis direction of the active roller 6, the two ends of the transition roller 8 are respectively connected to the frame 1 for rotation, and the transition roller 8 is higher than the active roller 6. A balancing roller 9 is also arranged on the lower side of the transition roller 8, the axis direction of the balancing roller 9 is parallel to the axis direction of the transition roller 8, the two ends of the balancing roller 9 are respectively connected to the frame 1 for rotation, and the balancing roller 9 is located between the transition roller 8 and the active roller 6 in the horizontal direction. In actual use, the staff passes the discharge end of the coil 200 between the active roller 6 and the passive roller 7, bypasses the transition roller 8 from the upper side, and bends downward and inward, so that the lower side of the discharge end of the coil 200 is attached to the outer side of the upper side of the transition roller 8. The staff bends the discharge end of the coil 200 inward, and then passes through the feeding device from the lower side of the balancing roller 9. The upper side of the discharge end of the coil 200 will be attached to the lower side of the outer side of the balancing roller 9. In this way, the bent coil 200 can be flattened, so that the coil 200 delivered by the feeding device becomes flat. At the same time, by adding multiple friction points on the discharge end of the coil 200, it helps to prevent the discharge speed from being too fast.

[0045] See also Figure 1-Figure 6, a monitoring assembly 91 is arranged at the lower side of the balancing roller 9, and the monitoring assembly 91 includes a photoelectric speed sensor 911, and the photoelectric speed sensor 911 is located at one end of the balancing roller 9 close to the equipment box 2, and the housing of the photoelectric speed sensor 911 is fixed to the frame 1. A reflective strip is correspondingly attached to the balancing roller 9, and a plurality of reflective strips can be arranged around the circumference of the balancing roller 9. The photoelectric speed sensor 911 is electrically connected to the PLC controller. During the discharge process of the coil 200, the discharge end of the coil 200 is tightly attached to the outer surface of the balancing roller 9, driving the balancing roller 9 to rotate. By monitoring the rotation speed of the balancing roller 9 through the photoelectric speed sensor 911, the discharge amount of the coil 200 can be accurately monitored. The PLC controller compares the detected rotation speed of the balancing roller 9 with the preset discharge speed, and controls the drive motor 611 and the push cylinder 711 according to the comparison result to adjust the discharge speed. This method helps to improve the automation degree of the feeding device.

[0046] The implementation principle of a precise feeding device for coiled material in the embodiment of the present application is as follows: the staff passes the discharge end of the coiled material 200 through the material gap between the active roller 6 and the passive roller 7, and bypasses the transition roller 8 and the balance roller 9, ensuring that the coiled material 200 is flat and close to the outer surface of the active roller 6, the transition roller 8 and the balance roller 9. After starting the PLC controller, the PLC controller first controls the extension and contraction of the push cylinder 711, so that the passive roller 7 is close to the outer surface of the coiled material 200. Then the drive motor 611 is started, and the drive motor 611 drives the active roller 6 to rotate, and the coiled material 200 is accurately pulled forward by friction. The photoelectric speed sensor 911 monitors the speed of the balance roller 9 in real time, and the PLC controller adjusts the drive component 61 and the push component 71 according to the detection result to ensure the accuracy and automation of the feeding process. Through this comprehensive design and operation, the feeding device ensures the accuracy and stability of feeding on the basis of improving work efficiency, and can adapt to the needs of coiled materials 200 of different thicknesses, and can fine-tune the feeding speed as needed to meet different production requirements.
