Detailed Implementation Methods
[0041] Example 1:
[0042] Please refer to Figures 1-5 This embodiment is a reversing conveyor mechanism 100 at the end of a circulating conveyor line, which includes a conveyor belt 1 arranged in a U-shape at the end. The conveyor belt 1 has a left conveyor belt 11, a rear conveyor belt 12 and a right conveyor belt 13 connected in sequence. A middle lifting guide component 2 extending forward and backward is provided between the left conveyor belt 11 and the right conveyor belt 13. An end input channel 10 is formed between the middle lifting guide component 2 and the left conveyor belt 11, and an end output channel 20 is formed between the middle lifting guide component 2 and the right conveyor belt 13. An input side lifting guide component 3 extending left and right is provided on the input side of the end input channel 10, and an output side lifting guide component 4 extending left and right is provided on the output side of the end output channel 20.
[0043] The end input channel 10 is connected to the first conveyor line 30, and the end output channel 20 is connected to the second conveyor line 40. The first conveyor line 30, the second conveyor line 40, and the end reversing conveyor mechanism 100 in this embodiment together constitute the circulating conveyor line 200.
[0044] The working principle of the end reversing conveyor mechanism 100 of the circulating conveyor line in this embodiment is as follows:
[0045] First, the input-side lifting guide assembly 3 is in a low position, and the middle lifting guide assembly 2 is raised to a high position. Under the conveying drive of the left conveyor belt 11, on the one hand, the carrier 300 can smoothly pass above the input-side lifting guide assembly 3 and enter the end input channel 10 from the first conveyor line 30; on the other hand, during the process of the carrier 300 entering the end input channel 10, the middle lifting guide assembly 2 can provide bottom support for the right side of the carrier 300, ensuring that the carrier 300 moves reliably and effectively.
[0046] Then, the input-side lifting guide assembly 3 and the output-side lifting guide assembly 4 rise to a high position, and the intermediate lifting guide assembly 2 descends to a low position. Driven by the rear conveyor belt 12, on the one hand, the carrier 300 can smoothly pass over the intermediate lifting guide assembly 2 and move from the end input channel 10 to the end output channel 20. On the other hand, during the process of the carrier 300 moving from the end input channel 10 to the end output channel 20, the input-side lifting guide assembly 3 and the output-side lifting guide assembly 4 can provide bottom support for the front of the carrier 300, ensuring that the carrier 300 moves reliably and effectively.
[0047] Finally, the intermediate lifting guide assembly 2 rises to the high position, and the output side lifting guide assembly 4 descends to the low position. Driven by the right-side conveyor belt 13, on the one hand, the carrier 300 can smoothly pass over the output side lifting guide assembly 4 and move from the end output channel 20 to the second conveyor line 40. On the other hand, during the process of the carrier 300 moving from the end output channel 20 to the second conveyor line 40, the intermediate lifting guide assembly 2 can provide bottom support for the left side of the carrier 300, ensuring that the carrier 300 moves reliably and effectively.
[0048] In cases where the entire conveyor line cannot extend to the end reversing section, this embodiment uses an inner conveyor belt 201 and an outer conveyor belt 202 to form a conveyor belt group for the circulating conveyor line 200. In this embodiment, the conveyor strip 1 is the outer conveyor belt 202. The outer conveyor belt extends to the end of the circulating conveyor line 200 and is U-shaped at the end. The U-shaped conveyor belt section is used to realize the input drive, lateral transfer drive, and output drive of the carrier 300, effectively solving the technical problem that the material has no transfer power drive in the end reversing section because the entire conveyor line cannot extend to the end reversing section.
[0049] To further provide more effective travel guidance for the movement of the carrier 300, this embodiment also includes an outer limiting guide component 5 arranged along the U-shaped section of the conveyor belt 1. The outer limiting guide component 5 provides peripheral limiting guidance for the carrier 300 when it moves within the end reversing section. Combined with the inner limiting guidance provided by the middle lifting guide component 2, the input-side lifting guide component 3, and the output-side lifting guide component 4, it effectively ensures that the carrier 300 moves along the set transfer path. The outer limiting guide component 5 includes a first limiting guide 51 parallel to the left side of the left conveyor belt 11, a second limiting guide 52 parallel to the rear side of the rear conveyor belt 12, and a third limiting guide 53 parallel to the right side of the right conveyor belt 13. In this embodiment, the first limiting guide 51, the second limiting guide 52, and the third limiting guide 53 have the same structure and each includes a first support plate 511 and a guide roller group 512 arranged along the length extension direction of the first support plate 511. The guide roller assembly 512 provides lateral restraint to the side of the carrier 300 and contacts the side of the carrier 300 through rolling friction, thereby reducing the frictional resistance to the side of the carrier 300. In other embodiments, the first limiting guide 51, the second limiting guide 52, and the third limiting guide 53 may also consist only of the first support plate 511, with the side of the first support plate 511 providing lateral restraint to the side of the carrier 300.
[0050] The middle lifting guide assembly 2 includes a first cylinder 21, a second support plate 22 that moves up and down under the influence of the first cylinder 21, a first lateral limiting member 23 disposed on the second support plate 22 and cooperating with the first limiting guide member 51 to guide and limit the left and right sides of the carrier 300, a first bottom support member 24 that provides bottom support for the right side of the carrier 300 during the process of the carrier 300 entering and exiting the end input channel 10, a second lateral limiting member 25 disposed on the second support plate 22 and cooperating with the third limiting guide member 53 to guide and limit the left and right sides of the carrier 300, and a second bottom support member 26 that provides bottom support for the left side of the carrier 300 during the process of the carrier 300 entering and exiting the end output channel 20.
[0051] In this embodiment, the first lateral limiting member 23, the first bottom support member 24, the second lateral limiting member 25, and the second bottom support member 26 all adopt a guide roller assembly structure. In other embodiments, the first lateral limiting member 23 and the second lateral limiting member 25 can also adopt lateral limiting blocks to guide and limit the sides of the vehicle 300; the first bottom support member 24 and the second bottom support member 26 can also adopt bottom support plates to provide bottom support for the vehicle 300.
[0052] The input-side lifting guide assembly 3 includes a second cylinder 31, a third support plate 32 driven by the second cylinder 31 to move up and down, a third lateral limiting member 33 disposed on the third support plate 32 and cooperating with the second limiting guide member 52 to guide and limit the front and rear sides of the carrier 300, and a third bottom support member 34 disposed to provide bottom support for the front side of the carrier 300 during the process of the carrier 300 entering and exiting the end input channel 10.
[0053] The output-side lifting guide assembly 4 includes a third cylinder 41, a fourth support plate 42 driven by the third cylinder 41 to move up and down, a fourth lateral limiting member 43 disposed on the fourth support plate 42 and cooperating with the second limiting guide member 52 to guide and limit the front and rear sides of the carrier 300, and a fourth bottom support member 44 disposed on the carrier 300 to provide bottom support for the front side of the carrier 300 during the process of the carrier 300 entering and exiting the end output channel 20.
[0054] In this embodiment, the third lateral limiting member 33, the third bottom support member 34, the fourth lateral limiting member 43, and the fourth bottom support member 44 all adopt a guide roller assembly structure. In other embodiments, the third lateral limiting member 33 and the fourth lateral limiting member 43 may also adopt lateral limiting blocks to guide and limit the sides of the vehicle 300; the third bottom support member 34 and the fourth bottom support member 44 may also adopt bottom support plates to provide bottom support for the vehicle 300.
[0055] To improve the stability of the carrier 300 as it moves between the end input channel 10 and the end output channel 20, this embodiment further includes a first inner support component 6 extending laterally between the rear conveyor belt 12 and the middle lifting guide component 2, and a second inner support component 7 located in front of the middle lifting guide component 2 and aligned with the gap between the input-side lifting guide component 3 and the output-side lifting guide component 4. During the movement of the carrier 300 between the end input channel 10 and the end output channel 20, the first inner support component 6 assists the rear conveyor belt 12 in providing bottom support for the rear side of the carrier 300. The second inner support component 7 compensates for the gap between the input-side lifting guide component 3 and the output-side lifting guide component 4, ensuring smooth movement of the carrier 300 between the end input channel 10 and the end output channel 20.
[0056] Both the first inner support assembly 6 and the second inner support assembly 7 include a fourth cylinder 61 and a support roller assembly 62 driven by the fourth cylinder 61 to move up and down. The support roller assembly 62 is arranged in the left-right direction.
[0057] In this embodiment, the end input channel 10 or the end output channel 20 is further provided with a lifting and positioning module 8 for lifting and positioning the carrier 300 upwards. The lifting and positioning module 8 includes a fifth cylinder 81 and a lifting plate 82 driven by the fifth cylinder 81 to move up and down. The lifting plate 82 is provided with a positioning pin 83 that is inserted into the positioning hole at the bottom of the carrier 300. The lifting plate 82 lifts the carrier 300 upwards, and the positioning pin 83 accurately positions the carrier 300, ensuring the positional accuracy of the carrier 300, thereby enabling the carrier 300 to perform feeding or receiving operations.
[0058] To further facilitate the transfer of the carrier 300 into position, a carrier pushing mechanism can be configured. Specifically, this embodiment also includes a pushing mechanism 9 for pushing the carrier 300 into position in the end output channel 20. The pushing mechanism 9 includes a sixth cylinder 91 and a pushing plate 92 driven by the sixth cylinder 91 to move left and right. The pushing plate 92 assists the rear conveyor belt 12 in pushing the carrier 300 from the end input channel 10 into the end output channel 20 and into position.
[0059] This embodiment also includes a first support pulley 14 located at the junction of the left conveyor belt 11 and the rear conveyor belt 12, and a second support pulley 15 located at the junction of the rear conveyor belt 12 and the right conveyor belt 13. A third support pulley 16 is provided between the input-side lifting guide assembly 3 and the output-side lifting guide assembly 4, and one end of the inner circumferential conveyor belt 201 of the circulating conveyor line 200 is wound around the third support pulley 16.
[0060] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
