Description

Technical Field

[0001] This invention relates to the field of loading and unloading technology, and more specifically, to a fully automatic loading and unloading device. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, to become deformed and less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, with a special grain layer on its surface, giving it a natural grain and luster, and a comfortable feel. As one of the most important materials in daily life and industry, leather processing often requires unwinding equipment. Typically, the unwinding equipment holds two rolls of material. During production, the material from the first station is unwound first; once the material from the first station is used up, the material from the second station is switched on to continue production.

[0003] In the existing unwinding equipment, the unwinding shaft at the first station needs to be removed by the worker, and then the worker needs to use a crane to lift the full roll of material to the first station for use. This back-and-forth operation is time-consuming and labor-intensive. At the same time, there are also safety risks due to the different skill levels of the workers. If the new roll of material is not placed before the material at the second station is used up, it will affect the operation of the subsequent processes.

[0038] Example 1

[0039] Refer to the instruction manual appendix Figure 1-3 , Figure 5 and Figure 9-10An embodiment of the present invention provides a fully automatic loading and unloading device, comprising a frame 1. A feeding trolley 2 and an unwinding machine 3 are sequentially arranged from left to right on the inner side of the frame 1. Two parallel linear slide rails 4 are fixedly mounted on the top of the frame 1. A fixed seat 5 is slidably mounted on the top of each of the two linear slide rails 4. A sliding frame 7 is mounted on opposite sides of each of the two fixed seats 5. A connecting beam 8 is fixed between the two sliding frames 7. A lifting motor 9 is mounted on one side of one of the fixed seats 5. A lifting reducer 10 is mounted on the output shaft end of the lifting motor 9. Two transmission gears 11 are fixedly mounted at the shaft head of the lifting reducer 10. Linear slide rails 12 are mounted on opposite sides of each of the two fixed seats 5 at the positions corresponding to the positions of the transmission gears 11. Each side is provided with a guide rack 15 that meshes with the transmission gear 11 at the corresponding position. The bottom end of the guide rack 15 facing the linear slide rail 2 12 is fixedly provided with a slide block 13. The slide block 13 is slidably connected to the linear slide rail 2 12 at the corresponding position. The bottom end of the slide block 13 is fixedly provided with a hoisting device 14. The bottom end of the hoisting device 14 is fixedly installed with a hook 16. The side and bottom end of the hook 16 are respectively fixedly provided with an infrared detector 17 and an infrared detector 2 18. The top of the frame 1 is fixedly installed with a screw jack 19 at the position corresponding to the top of the unwinding machine 3. The output end of the screw jack 19 is fixedly connected to the connecting beam 8. The inside of the frame of the unwinding machine 3 is provided with a drive shifting mechanism. The top of the unwinding trolley 2 is provided with a stop block 20 with a triangular prism structure.

[0040] Furthermore, the drive shifting mechanism includes two discs 26 rotatably mounted inside the frame of the unwinding machine 3 via rotating rods, and a drive assembly 21 located at the bottom of the disc 26 at the specified position. The drive assembly 21 includes a support fixed inside the frame of the unwinding machine 3. A drive wheel is installed on the top of the support corresponding to the position of the disc 26 at the specified position. The drive wheel is driven by a servo motor. Two ultrasonic sensors 22 and two shaft clamping mechanisms 6 are installed on opposite sides of the two discs 26. The line connecting the two shaft clamping mechanisms 6 at the specified position and the line connecting the two ultrasonic sensors 22 are arranged in a cross shape. The two ultrasonic sensors 22 and the shaft clamping mechanisms 6 at the specified position are arranged in a one-to-one correspondence.

[0041] It should be noted that the unloading trolley 2 can store raw material rolls and empty unloading shafts, and the unloading trolley 2 can move left and right driven by a motor; during the process of the transmission gear 11 rotating and driving the guide rack 15 to move up and down, the linear slide rail 12 and the slide block 13 are used for guidance and support; the screw jack 19, driven by a servo motor, drives the entire lifting component to move back and forth between the unloading trolley 2 and the unwinding machine 3. In the production process, when the raw material roll at the first station is unwound and becomes an empty unwinding shaft, the ultrasonic sensor 22 senses it and sends a signal. The servo motor drives the drive wheel to rotate, thereby driving the disc 26 to rotate 180°, realizing the switching position between the empty material shaft and the material roll. At the same time, the servo motor of the upper screw jack 19 starts, moving the entire lifting component above the empty material unloading shaft and then stopping. The infrared detector 18 at the bottom of the hook 16 is used for precise positioning. Then, the upper lifting motor 9 starts, driving the lifting reducer 10 to rotate. The transmission gear 11 installed at the shaft head of the lifting reducer 10 also rotates. While the transmission gear 11 rotates, the guide rack 15 moves linearly. With the support and limit of the slide rail 12 and the slide block 13, the lifting device 14 moves downward, and at the same time, the hook 16 below the lifting device 14 moves downward synchronously. When the infrared detector 17 on the side of the hook 16 senses the empty feed shaft and displays the distance, indicating that the hook 16 is parallel to the empty feed shaft, the hook 16 moves parallel until it hooks the empty feed shaft. The infrared detector 17 displays the distance value that the empty feed shaft is inside the hook 16, the lifting motor 9 starts, and drives the empty feed shaft to move upward. After disengaging from the shaft clamping mechanism 6 on the unwinding machine 3, it moves upward in a spiral lifting motion. Driven by the machine 19, the material roll moves horizontally to the designated position on the top of the unloading trolley 2. The lifting motor 9 controls the hook 16 to descend, placing the empty unloading shaft on the unloading trolley 2. The hook 16 continues to move downward. The distance displayed by the external detector 17 indicates that the hook 16 has separated from the empty unloading shaft. The hook 16 is then controlled to move laterally until it leaves the empty unloading shaft and rises to a certain height before stopping. Similarly, the loading process of the raw material roll is exactly the opposite of the unloading process of the empty unloading shaft. That is, the hook 16 moves to the center of the raw material roll and lifts the raw material roll to the corresponding working position on the unwinding machine 3.

[0042] In this embodiment, two parallel slide rails 23 are fixedly installed on the bottom inner side of the frame 1. The feeding trolley 2 is slidably installed between the tops of the two slide rails 23. The feeding trolley 2 can be driven by a motor to move along the slide rails 23 to a designated position.

[0043] In this embodiment, rubber rings 27 are fixedly fitted on the outer circumferential surfaces of both discs 26. The rubber rings 27 can increase the contact friction between the discs 26 and the drive wheel, so that the discs 26 can accurately reach the corresponding working positions during rotation.

[0044] In this embodiment, four sets of stop blocks 20 are provided, with two in each set. Each set of two stop blocks 20 is fixedly covered with a rubber pad 24 on one side opposite to the other. The two sets of stop blocks 20 arranged opposite to each other can be used to position the raw material roll or empty feed shaft, and the rubber pad 24 is used to stably hold the raw material roll or empty feed shaft.

[0045] Example 2

[0046] Refer to the instruction manual appendix Figure 5-8 According to one embodiment of the present invention, the locking mechanism 6 includes a movable plate 61 rotatably mounted on the surface of a disc 26 via a rotating rod. A counterweight 62 is fixedly provided at the bottom center of the movable plate 61. Two circular rods 63 are fixedly provided on the side of the movable plate 61 away from the disc 26, arranged symmetrically about the vertical central axis of the movable plate 61. Two limiting plates 64 are fixedly provided at the ends of the two circular rods 63 away from the movable plate 61. A deflection locking block 65 is rotatably mounted on the outer circumference of the circular rods 63 at the position between the two limiting plates 64. A support plate 69 is fixedly provided at the bottom center of the side of the movable plate 61 away from the disc 26. A spring-loaded frame 66 is fixedly provided at the top of the support plate 69. Two side plates 67 are also fixedly provided on the side of the movable plate 61 away from the disc 26, arranged symmetrically about the vertical central axis of the movable plate 61. An inclined support plate 68 is fixedly provided on the opposite side of the two side plates 67.

[0047] It should be noted that when the locking mechanism 6 is in an idle state, the two deflection blocks 65 are pushed open by the elastic action of the spring frame 66, and the two inclined support plates 68 support the deflection blocks 65 on their respective sides; the movable plate 61 remains as shown in the appendix of the instruction manual under the action of the counterweight 62. Figure 5 During the unwinding process, the movable plate 61 remains in this state. When loading the raw material roll, as the two ends of the unwinding shaft on the raw material roll are placed between the two deflection blocks 65 on the corresponding shaft clamping mechanism 6, the two open deflection blocks 65 will be pressed down by gravity as the raw material roll falls, causing the two deflection blocks 65 to deflect towards each other about the circular rod 63 at their respective positions, thereby automatically clamping the unwinding shaft. Similarly, when disassembling the empty unwinding shaft, simply lift the empty unwinding shaft upwards and use the elastic restoring force of the spring frame 66 to push open the two closed deflection blocks 65 to release the clamping state of the empty unwinding shaft.

[0048] Example 3

[0049] Refer to the instruction manual appendix Figure 3-4According to an embodiment of the present invention, a fully automatic loading and unloading device is provided with a guide component 25 on the inner side of the frame of the unloading trolley 2 corresponding to the positions of each set of blocks 20. Each guide component 25 includes a horizontal plate 251 fixedly disposed on the inner side of the frame of the unloading trolley 2 and an inclined plate 254 fixedly disposed between the horizontal plate 251 and the inner side of the frame of the unloading trolley 2. A vertical plate 252 is fixedly disposed at one end of the horizontal plate 251, and a guide block 253 is fixedly disposed at the top of each vertical plate 252.

[0050] It should be noted that the two guide blocks 253, which are arranged opposite each other, are flared at their top ends. During the process of placing the raw material roll on the top of the feeding trolley 2, the two guide blocks 253 can be used to correct the position of the raw material roll, so that the raw material roll is centered and the subsequent roll changing operation can be accurately performed.
