[0020] The present utility model will be further described below in conjunction with the attached drawings of the specification.
[0021] As Figure 1 、 2 shown, a winding material loading device includes an AGV cart 9 and a lifting tooling arranged on the AGV cart 9. The AGV cart 9 includes a vehicle body and a lifting platform 91 arranged on the vehicle body. The lifting tooling is arranged on the lifting platform 91. The AGV cart 9 travels between the material storage area and the unwinding mechanism according to the planned route. The AGV cart 9 is responsible for transporting the winding material. The lifting tooling moves along with the AGV cart 9 and is responsible for lifting the winding material to a specified height for loading. The lifting tooling can be fixed on the AGV cart 9 or can adopt a quick-release connection. The AGV cart 9 can cooperate with different toolings to achieve different functions.
[0022] As Figure 1 、 2 shown, the lifting tooling includes two parallel and equally high material supporting shafts 2, swing arms 3 arranged at both ends of the material supporting shafts 2, a driving mechanism for driving the swing arms 3 to swing, and a support frame 7.
[0023] As Figure 1 、 2 shown, the support frame 7 is in a shape of "Ji", and includes a top plate 71 and side plates 72 located on both sides of the top plate 71. The lower ends of the side plates 72 integrally form a supporting portion 73 outward; the support frame can cooperate with the lifting platform 91 of the AGV cart 9. The top plate 71 of the support frame 7 is fixed on the lifting platform of the AGV cart 9, and can be connected by bolts or by pins. When using pin connection, the support frame 7 is placed on the tooling frame through the supporting portion 73, and the AGV cart 9 can take out the lifting tooling as needed, so that the multi-functional use of the AGV cart 9 can be realized; after the support frame is combined with the AGV cart 9, the side plates 72 of the support frame 7 are located on both sides of the AGV cart 9, which can not only protect the AGV cart 9, but also reduce the height of the lifting tooling, contributing to realizing low-position feeding.
[0024] As Figure 1 、 2As shown, the two swing arms 3 on the same side of the material support shaft 2 cross each other. The swing arms 3 are V-shaped. The upper ends of the swing arms 3 are connected to the material support shaft 2, and the lower ends of the swing arms 3 serve as rotation fulcrums and are rotatably connected to the side surface of the support frame 7, so that the material support shaft 2 is located above the top of the support frame 7. By adopting a scissor-cross type lifting mechanism, the lifting range of the material support shaft 2 is larger, and the effect of low-position feeding can be achieved.
[0025] As Figure 1 , 2 shown, the drive mechanism drives the two swing arms 3 on the same side to move in opposite directions. It includes a screw rod 8 with two sections of reverse threads, two nut seats 5 symmetrically arranged on the screw rod 8, and a power source 6 for driving the screw rod 8 to rotate. The screw rod 8 is arranged at the top of the support frame 7 below the material support shaft 2, and the screw rod 8 is perpendicular to the material support shaft 2. The two nut seats 5 correspond to the two material support shafts 2 respectively. The nut seats 5 are strip-shaped and are arranged parallel to the material support shaft 2. The nut seats 5 are slidably matched with the top plate 71 of the support frame through sliding components. Support rollers 4 acting on the swing arms 3 are arranged at both ends of the nut seats 5. The nut seats 5 drive the support rollers 4 to push the swing arms 3 to swing. When the two nut seats 5 approach each other, the two material support shafts 2 approach each other to achieve lifting. When the two nut seats 5 move away from each other, the two material support shafts 2 move away from each other to achieve lowering. The power source 6 includes a worm and worm gear mechanism. The motor drives the screw rod 8 through the worm and worm gear mechanism. The worm and worm gear have a self-locking function to prevent the coil material from sliding down automatically during the up and down feeding and transportation process. The screw rod 8 and the nut seats 5 cooperate. With the cooperation of the absolute encoder, the motor can achieve high-precision lifting.
[0026] As Figure 3 , 4As shown in the figure, the material supporting shaft 2 includes a shaft core 22 and a roller 23 sleeved on the shaft core 22. One end of the shaft core 22 is provided with a stop platform 21 that abuts against one end face of the roller 23, and the end of the stop platform 21 is fixedly connected to the swing arm 3; the other end of the shaft core 22 is connected to the swing arm 3 on the other side. An accommodation groove 26 is provided inside one end of the roller 23, a spring 24 is provided inside the accommodation groove 26, the spring 24 is sleeved on the shaft core 22, one end of the spring 24 abuts against the stop surface 27 inside the accommodation groove 26, and the other end of the spring 24 abuts against the swing arm 3, forcing the roller 23 to closely adhere to the stop platform 21 under the action of the spring 24. A first through hole penetrating through both ends of the roller 23 is provided inside the roller 23, the shaft core 22 passes through the first through hole, a second through hole is provided at one end of the roller 23, the diameter of the first through hole is smaller than that of the second through hole, the stop surface is formed at the transition between the first through hole and the second through hole, and the second through hole forms the accommodation groove 26. The other end of the shaft core 22 passes through the accommodation groove 26 and extends out of the roller 23 to form an extension section, and the length of the extension section is the same as that of the stop platform 21, ensuring that the roller 23 is in the middle position between the two swing arms 3 at both ends; a telescopic sleeve 25 is sleeved on the extension section, the spring 24 is provided between the extension section and the telescopic sleeve 25, and the telescopic sleeve 25 can protect the extended spring 24 and the shaft core 22; the telescopic sleeve 25 is a corrugated pipe, one end of the corrugated pipe is provided with a connecting pipe, the connecting pipe is inserted into the accommodation groove 26, and during the transverse movement of the roller 23, the corrugated pipe expands and contracts adaptively.
[0027] Principle of the present utility model: The material supporting shaft 2 is installed at the upper end of the swing arm 3, and the two cross - arranged swing arms 3 jointly support and lift the winding material 1 through the material supporting shaft 2, so that it can reach the feeding height; during feeding, the cone tip at one end of the unwinding mechanism first extends into one end of the winding material 1, and the cone tip at the other end of the unwinding mechanism then extends into the other end of the winding material 1, thus completing the feeding of the winding material 1. During the feeding process, the winding material 1 may rotate on the lifting mechanism. Since the roller 23 can rotate around the shaft core 22, it prevents damage to the winding material 1; since the roller 23 can move transversely along the shaft core 22 and achieve automatic reset, it prevents damage to the surface of the winding material 1 during the process of the cone tip clamping the winding material 1. The AGV cart 9 serves as the moving platform of the lifting tooling, and the lifting tooling serves as the lifting platform of the winding material. The lifting height of the AGV cart plus the lifting height of the lifting tooling is equal to the lifting height of the center of the winding material. The lifting tooling compensates for the lifting height of the lifting platform of the AGV cart 9, enabling the feeding device to adapt to the feeding of winding materials with different diameters; during feeding, the winding material is transported to the lifting tooling manually or by a robotic arm. The two material supporting shafts support on both sides of the bottom of the winding material. The AGV cart 9 transports the winding material to the feeding station according to the preset path, and the lifting tooling lifts the winding material to the designated position according to the center position of the diameter. Subsequently, the cone tips of the unwinding mechanism clamp both ends of the winding material.
