Technical Field

[0001] The present invention relates to the technical field of coil conveying, and specifically to a coil production conveyor. Background Art

[0002] At present, the construction industry is developing faster and faster, and the demand for large coils is also increasing. Among them, waterproof coils are a kind of waterproof material that plays a crucial role in the whole project. In manufacturing enterprises that produce waterproof coils, the degree of automation is also getting higher and higher. After the coiled materials are wound and bundled, they need to be conveyed and loaded onto vehicles.

[0003] For the bundled coils, they are generally conveyed by forklifts. Then, U-shaped hooks are used to hook the steel coils, and then they are hoisted onto large trucks. This requires additional command personnel and operators who use hoisting equipment to load the vehicles when loading the coils. These personnel are all in positions close to the coils. Once the bundling ropes of the coils break or the coils accidentally fall, the personnel near the coils are in life danger, and the existing coil conveying and loading equipment lacks safety.

[0006] As a further improvement of the present invention: The rotating and lifting mechanism includes a frame fixedly connected to the vertical frame. The frame is fixedly connected to a machine base. Two groups of parallel hinge plates are hinged on both sides of the machine base. The hinge plates are jointly hinged to a table body. The table body is connected to the coil limiting mechanism. One group of hinge plates is fixedly connected to a boosting frame, and the boosting frame is hinged to a second active telescopic rod hinged to the frame.

[0007] As a further improvement of the present invention: The coil limiting mechanism includes a first motor fixedly connected to the table body, and the output shaft of the first motor is fixedly connected to a V-shaped support table rotatably connected to the table body.

[0010] As a further improvement of the present invention: The height adjustment mechanism includes multiple sets of sleeves fixedly connected to the vehicle body.

The transport trolley on the track drives the height adjustment mechanism to move, and the height adjustment mechanism drives the coil clamping mechanism to move towards the coil on the coil limiting mechanism, and the coil clamping mechanism clamps the coil. Then, the transport trolley drives the height adjustment mechanism away from the coil limiting mechanism. Under the height adjustment of the height adjustment mechanism for the coil clamping mechanism, the coil clamping mechanism places the coil on the transport vehicle. During this period, the locking mechanism releases the limit on the rotation and lifting mechanism, and the rotation and lifting mechanism resets, so that while the lifting and loading structure performs the loading operation, the pre-lifting structure preloads and lifts the next group of coils to be loaded. Through the cooperation between the pre-lifting structure and the lifting and loading structure, the present invention enables the lifting operation and the loading operation to be carried out simultaneously, improving the working efficiency of the present invention. Since the forklift is avoided from directly transporting the coil to the vehicle, the coil loading operation can be completed when the personnel are away from the coil and the loading vehicle. Even if a coil rolling event occurs, the safety of the personnel can be guaranteed, and the safety of the coil when being transported to the vehicle is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0016] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0017] Example 1. Refer to Figures 1 to 9 , a coil production conveyor, including an upright frame 1, a controller is installed on the upright frame 1, and further includes: A pre-lifting structure 2 connected to the upright frame 1. The pre-lifting structure 2 includes a rotating and lifting mechanism 3 connected to the upright frame 1. A coil limiting mechanism 4 is installed on the rotating and lifting mechanism 3. The rotating and lifting mechanism 3 is used to adjust the height of the coil limiting mechanism 4. The coil limiting mechanism 4 is used to support the coil. The rotating and lifting mechanism 3 is connected to a locking mechanism 5. The locking mechanism 5 is used to provide limit protection for the rotating and lifting mechanism 3; A hoisting and loading structure 6 connected to the upright frame 1. The hoisting and loading structure 6 includes two groups of tracks 7 connected to the upright frame 1. A carrier trolley 8 is installed on the tracks 7. A retaining wheel block is installed on the tracks 7. A height adjusting mechanism 9 is installed on the carrier trolley 8. The height adjusting mechanism 9 is connected to a coil clamping mechanism 10 adapted to the pre-lifting structure 2.

[0018] When in use, the transport vehicle is parked at the lower part of the stand 1 to transport the coil to the coil limiting mechanism 4. The transport method can be selected as setting the coil limiting mechanism 4 at the terminal of the assembly line to receive the coil, or using a forklift for active transportation, and then using the rotating lifting mechanism 3 to lift the coil limiting mechanism 4, the locking mechanism 5 limits the rotating lifting mechanism 3, thereby preventing the rotating lifting mechanism 3 from accidentally falling, the transport trolley 8 on the track 7 drives the height adjustment mechanism 9 to move, the height adjustment mechanism 9 drives the coil clamping mechanism 10 to move toward the coil limiting mechanism 4, and the coil clamping mechanism 1 0 performs a clamping operation on the coil, and the height adjustment mechanism 9 lifts the coil clamping mechanism 10, so that the coil is separated from the coil limiting mechanism 4, and then the transport trolley 8 drives the height adjustment mechanism 9 away from the coil limiting mechanism 4. Under the height adjustment mechanism 9 of the coil clamping mechanism 10, the coil clamping mechanism 10 places the coil on the transport vehicle. During this period, the locking mechanism 5 releases the limit of the rotating lifting mechanism 3, and the rotating lifting mechanism 3 is reset, so that the pre-lifting structure 2 preloads and lifts the next group of coils to be loaded while the lifting and loading structure 6 performs the loading operation. The present invention cooperates with the pre-lifting structure 2 and the lifting and loading structure 6, so that the lifting operation and the loading operation are carried out at the same time, which improves the work efficiency of the present invention. Since the forklift is prevented from directly transporting the coil to the vehicle, the coil loading operation is completed when the personnel are away from the coil and the loading vehicle. Even if the coil rolls off, the safety of the personnel can be guaranteed, and the safety of the coil when it is transported to the vehicle can be improved.

[0019] In one case of this embodiment, the rotating lifting mechanism 3 includes a frame 11 fixedly connected to the stand 1, the frame 11 is fixedly connected to a base 12, two sets of parallel hinged plates 13 are hinged on both sides of the base 12, the hinged plates 13 are jointly hinged to a platform 14, the platform 14 is connected to the coil limiting mechanism 4, one set of hinged plates 13 is fixedly connected to a power-assisting frame 15, the power-assisting frame 15 is hinged to a second active telescopic rod 16 hinged to the frame 11, the second active telescopic rod 16 can be an electric telescopic rod or a hydraulic telescopic rod. The second active telescopic rod 16 pulls the power-assisting frame 15 to drive a set of hinged plates 13 to rotate, so that the hinged plates 13 drive the platform 14 to move, and the platform 14 drives the coil limiting mechanism 4, so as to adjust the height of the coil limiting mechanism 4.

[0020] In one case of this embodiment, the coil limiting mechanism 4 includes a first motor 17 fixedly connected to the platform 14, and the output shaft of the first motor 17 is fixedly connected to a V-shaped support platform 18 rotatably connected to the platform 14, and the V-shaped support platform 18 is used to carry the coil. The first motor 17 drives the V-shaped support platform 18 to rotate, thereby adjusting the direction of the V-shaped support platform 18, thereby improving the convenience of loading the coil onto the V-shaped support platform 18.

[0021] In a case of this embodiment, the latch mechanism 5 includes an extension frame 19 fixedly connected to the table body 14. An L-shaped rod 20 is slidably mounted on the extension frame 19. The L-shaped rod 20 is fixedly connected to a pressing piece 21. A first spring is installed between the pressing piece 21 and the extension frame 19. The first spring has ferromagnetism. A first electromagnet 22 is fixedly installed at one end of the L-shaped rod 20. The L-shaped rod 20 is slidably connected to a hinge seat 23. The hinge seat 23 is rotatably connected to a bayonet frame 24 hinged to the extension frame 19. A bayonet 25 is formed on the bayonet frame 24. An arc-shaped groove 26 for slidably connecting the hinge seat 23 is formed on the extension frame 19. A bayonet shaft 27 adapted to the bayonet 25 is installed on one set of the hinge plates 13. An arc-shaped surface cooperating with the bayonet shaft 27 is formed on the bayonet frame 24. As the hinge plate 13 rotates and lies flat, the bayonet shaft 27 presses the bayonet frame 24, causing the bayonet frame 24 to rotate. The hinge seat 23 rotates accordingly. Under the extrusion of the first spring on the pressing piece 21, the L-shaped rod 20 drives the hinge seat 23, causing the bayonet frame 24 to reset, so that the bayonet 25 clamps the bayonet shaft 27, thereby completing the limiting of the hinge plate 13. The latch mechanism 5 is used to limit the hinge plate 13 when the hinge plate 13 lies flat, thereby preventing the table body 14 and the coil limiting mechanism 4 from swinging and falling like a pendulum in case of accidental power failure, protecting the safety of personnel. When the first electromagnet 22 magnetically attracts the first spring, the first spring contracts. The first spring drives the L-shaped rod 20 through the pressing piece 21. The L-shaped rod 20 drives the bayonet frame 24 to rotate through the hinge seat 23, causing the bayonet 25 to disengage from the bayonet shaft 27, thereby releasing the limit of the latch mechanism 5 on the hinge plate 13. In a case of this embodiment, the carrier trolley 8 includes a vehicle body 28. Four groups of wheels 29 are rotatably mounted on the vehicle body 28. A power unit 30 is installed on the vehicle body 28. The power unit 30 can be a servo motor or a stepper motor. The power unit 30 is connected to two groups of wheels 29. Specifically, the power unit 30 is a second motor 31 fixedly connected to the vehicle body 28. The second motor 31 is connected to a transmission 32 connected to the vehicle body. The transmission 32 can be a continuously variable transmission mechanism or a stepped transmission mechanism. The output shaft of the transmission 32 is coaxially connected to two groups of wheels 29. The vehicle body 28 is connected to the height adjustment mechanism 9. The power of the power unit 30 is transmitted to two groups of wheels 29 through the transmission 32, so that the carrier trolley 8 moves on the track 7.

[0022] In one case of this embodiment, the height adjustment mechanism 9 includes multiple sets of sleeves 34 fixedly connected to the vehicle body 28. A first active telescopic rod 35 is fixedly installed inside the sleeve 34. The first active telescopic rod 35 can be an electric telescopic rod or a hydraulic telescopic rod. A slide bar 36 slidably connected to the sleeve 34 is fixedly installed at the mobile end of the first active telescopic rod 35. The slide bar 36 is fixedly connected to the coil clamping mechanism 10. The first active telescopic rod 35 adjusts the height of the coil clamping mechanism 10 by driving the slide bar 36 to move.

[0023] In one case of this embodiment, the coil clamping mechanism 10 includes a clamping seat 37 fixedly connected to the slide bar 36. A double-output shaft motor 38 is fixedly installed in the middle of the clamping seat 37. A screw rod 39 is fixedly connected to the output shaft of the double-output shaft motor 38. The screw rod 39 is threadedly connected to a clamping arm 40 slidably connected to the clamping seat 37. Driven by the double-output shaft motor 38, the screw rod 39 rotates, and the rotating screw rod 39 drives the clamping arm 40 to slide along the groove on the clamping seat 37, thereby adjusting the distance between the clamping arms 40. The clamping arms 40 are used to clamp the coil.

[0024] Embodiment 2, on the basis of Embodiment 1, refer to Figure 2 , Figure 3 , Figure 9 , the table body 14 is fixedly connected to a chassis 41. The chassis 41 is rotatably connected to a rotating shaft 42 coaxially connected to the wheel 29. The rotating shaft 42 is fixedly connected to a central disc 43. A second electromagnet 44 is installed inside the chassis 41. The second electromagnet 44 is connected to a friction plate 45 through a second spring. The second spring has ferromagnetism. The friction plate 45 is slidably installed inside the chassis 41. The machine base 12 is fixedly connected to a limit frame 46 adapted to the hinge plate 13. During normal operation, the second electromagnet 44 magnetically attracts the second spring, causing the friction plate 45 to disengage from the central disc 43. Once a power outage occurs, under the push of the second spring, the friction plate 45 presses against the central disc 43, thereby applying resistance to the rotating central disc 43, and further reducing the falling speed of the rotating and lifting mechanism 3. And under the limitation of the limit frame 46 on the hinge plate 13, the rotating and lifting mechanism 3 is prevented from swinging back and forth.
