[0061] Figure 4 Part of the structure of the lifting device provided by the embodiment of the utility model is shown, Figure 5 The partial enlarged view with the structure mark B is shown. Figure 4 Referring to Figure 4 And Figure 5 The lifting device further comprises an anti-loosening mechanism 730. The anti-loosening mechanism 730 is arranged on the inner wall of the basket mechanism 100 and is connected to the lifting rope 720 and is in communication connection with the control device 20 of the stacker. The anti-loosening mechanism 730 is used for detecting the state of the lifting rope 720, when the anti-loosening mechanism 730 detects that the lifting rope 720 is loosened or broken, the control device 20 can send an abnormal lifting rope prompt. The above abnormal prompt can be prompt information displayed on the display screen of the control device 20, alarm of a buzzer or turning on of a warning light and the like.

[0062] Specifically, referring to Figure 5 And Figure 7The anti-loosening mechanism 730 comprises a pull rod 731, an elastic element 732 and a detection switch 733, the pull rod 731 is connected to the lifting rope 720 and the basket mechanism 100, in the embodiment, the basket mechanism 100 is provided with a crossbeam 141, the pull rod 731 penetrates the crossbeam 141 in the vertical direction, the upper end is connected to the lifting rope 720, and the lower end is provided with a pull rod head, the cross-sectional area of the pull rod head is larger than that of the pull rod 731, the elastic element 732 is coaxially sleeved outside the pull rod 731, and the two ends are respectively abutted against the upper end surface of the pull rod head and the lower end surface of the crossbeam 141, the elastic element 732 has a compression state and a rebound state, when the lifting rope 720 is in a tension state, the elastic element 732 is in the compression state, when the lifting rope 720 is in a relaxation state or appears to be broken, the elastic element 732 is in the rebound state and pushes the pull rod 731 away from the crossbeam 141, the detection switch 733 is installed below the pull rod 731 and is communicatively connected to the control device 20, when the lifting rope 720 is in a relaxation state, the pull rod 731 can press and trigger the detection switch 733 under the action of the elastic element 732 in the rebound state, when the detection switch 733 is triggered, the control device 20 can issue a lifting rope abnormality prompt.

[0063] Figure 6 Part structure disassembly schematic diagram of the lifting device is shown, referring to Figure 4 and Figure 6 The lifting device further comprises a fork 200. The basket mechanism 100 is provided with an opening 110 at the side, and the fork 200 is arranged in the basket space and can extend out of the opening 110 to take and place goods. Through the fork 200, the goods in the basket space can be placed on the goods shelf, or the goods on the goods shelf can be taken to the basket space.

[0064] As an option, in the embodiment, the opening 110 is arranged at the opposite sides of the basket mechanism 100, and the fork 200 can extend out of the basket space from any opening 110. Through the above arrangement, the taking and placing of goods can be realized in two directions of the basket mechanism 100, and the flexibility of taking and placing goods is improved.

[0065] Specifically, the fork 200 is provided with a goods shelf detection member 210, which is communicatively connected to the control device 20 and can detect the relative position of the fork 200 and the goods shelf and transmit a position signal to the control device 20, so that the control device 20 can control the extension and retraction of the fork 200 according to the position signal, avoid the collision between the fork 200 and the goods shelf, and improve the reliability of the fork 200.

[0066] Specifically, in the embodiment, the fork 200 comprises a fixed section and a movable section. The fixed section is arranged in the basket space and parallel to the relative arrangement direction of the two openings 110. The movable section is movably connected to the fixed section and can slide along the length direction of the fixed section to extend out of any opening 110. It can be understood that one side of each opening 110 is provided with a shelf, so that when the fork extends out of an opening 110, the goods on the shelf corresponding to the opening 110 can be forked.

[0067] The movable section is provided with a shelf detection member 210 at both ends, so as to detect the relative position between the end of the movable section and the shelf when the movable section extends out of the basket space from the direction of the two openings 110 and approaches the shelves on both sides. It can be understood that when the movable section extends out of different openings 110, the end facing the shelf is different, for example, as shown in Figure 4 The movable section comprises a first end 220 and a second end 230. The first end 220 and the second end 230 are both provided with a shelf detection member 210. When the movable section extends out of one of the openings 110, the first end 220 faces the shelf, and at this time the shelf detection member 210 on the first end 220 can detect the relative position of the shelf on this side. When the movable section extends out of the other opening 110, the second end 230 faces the shelf on the other side, and at this time the shelf detection member 210 on the second end 230 can detect the relative position of the shelf on this side.

[0068] More specifically, the opening 110 is also provided with a first detection member 910 and a second detection member 920. The first detection member 910 and the second detection member 920 are specifically arranged at the inner bottom of the basket space corresponding to the opening 110 and can detect the goods on the shelf, wherein the detection distance of the detection light of the first detection member 910 and the detection distance of the detection light of the second detection member 920 are different. In the embodiment, the detection distance of the detection light of the first detection member 910 is smaller than the detection distance of the detection light of the second detection member 920, wherein the detection light of the first detection member 910 is used to detect the goods placed closer to the edge of the shelf, and the detection light of the second detection member 920 is used to detect the goods placed farther away from the edge of the shelf. Through the above arrangement, the position information and the placement state information of the goods on the shelf can be accurately obtained, the problem that the goods cannot be detected due to the placement position being far away from the edge of the shelf can be avoided, and the lifting of the basket mechanism 100 and the extension and retraction of the fork 200 can be accurately controlled by the control device 20, thereby improving the accuracy of goods picking.

[0069] Continuing to refer to Figure 4 and Figure 6The lifting device also includes a size detection component 300. This component 300 is located at the opening 110 and is used to sense the cargo, limiting the maximum height and width of cargo that can enter the basket space through the opening 110. The size detection component 300 is communicatively connected to the control device 20. It can send cargo overheight and overwidth signals to the control device 20. When the control device 20 receives these signals, it stops the forks 200 from extending, preventing overheight and overwidth cargo from colliding when entering the basket space through the opening 110.

[0070] Specifically, such as Figure 4 As shown, the size detection assembly 300 includes a plurality of first through-beam sensors 310. A portion of these first through-beam sensors 310 forms a limit height detection ray 1, and another portion forms a limit width detection ray 2. In this embodiment, a first through-beam sensor 310 is respectively disposed at the top of both sides of the opening 110 in the width direction, and the aforementioned limit height detection ray 1 is formed between two first through-beam sensors 310. A first through-beam sensor 310 is respectively disposed at each of the four apex corners of the opening 110, and through-beam limit width detection rays 2 can be formed between two corresponding first through-beam sensors 310 in the height direction of the opening 110.

[0071] When the cargo is too tall, it will block the limit height detection beam 1. At this time, the control device 20 can receive the cargo being too tall signal. When the cargo is too wide or its placement is tilted relative to the opening 110, it will block one or two limit width detection beams 2. At this time, the control device 20 can receive the cargo being too wide signal.

[0072] More specifically, the lifting device also includes a status detection component 400. This status detection component 400 is disposed within the basket mechanism 100 and can detect the placement status of goods within the basket space. It can also transmit the placement status signal of the goods to the control device 20, allowing the control device 20 to provide alerts regarding the status of the goods and prevent damage to the basket mechanism caused by the goods tilting within the basket space. In this embodiment, the control device 20 is equipped with a display screen, which can display the placement status of the goods within the basket space, allowing operators to be promptly informed.

[0073] More specifically, the state detection component 400 includes a plurality of second through-beam sensors 410, which can form a deflection state detection ray 3 in the basket space. The deflection state detection ray 3 is spaced apart from the side of the basket mechanism 100, and when the placement state of the goods deviates, the deflection state detection ray 3 is blocked by the goods. In this embodiment, four second through-beam sensors 410 are specifically arranged on one side of the basket space. The four second through-beam sensors 410 are respectively arranged at the four apex corners of the side of the basket space, forming an X-shaped intersecting deflection state detection ray 3, as shown below. Figure 6 As shown.

[0074] Figure 8 Show Figure 6 A magnified view of the structure marked D in the middle. (Refer to...) Figure 4 , Figure 6 and Figure 8 The lifting device also includes a cargo detector 500. The cargo detector 500 is disposed on the side of the basket mechanism 100, outside the basket space. A detection port 120 is opened on the side of the basket mechanism 100, allowing the cargo detection ray 4 of the cargo detector 500 to pass through the detection port 120 and enter the basket space. The cargo detection ray 4 is used to detect whether the basket space contains cargo. In this embodiment, the lifting device also includes a cargo ray receiver 510, which is disposed within the basket space, forming a cargo detection ray 4 diagonally opposite the cargo detector 500 within the basket space. When cargo is present in the basket space, the cargo can block the cargo detection ray 4, at which point the control device 20 can detect the presence of cargo in the basket space.

[0075] Continue to refer to Figure 4 and Figure 6 The basket mechanism 100 includes a basket body 130 and a basket frame 140. The basket frame 140 is movably connected to the column device 10, and the basket body 130 is disposed within the basket frame 140, with the basket space formed within the basket body 130. The basket frame 140 provides protection for the basket body 130, improving the structural reliability of the basket mechanism 100.

[0076] Continue to refer to Figure 4 The lifting device also includes a deceleration sensor switch 610. The deceleration sensor switch 610 is located on the side of the basket lifting mechanism 100. Deceleration sensors are located at the top and bottom of the column device 10. The deceleration sensor switch 610 is triggered when it approaches a deceleration sensor. When the deceleration sensor switch 610 is triggered, the control device 20 can control the basket lifting mechanism 100 to reduce its lifting speed.

[0077] Further, the lifting device further comprises a stop induction switch 620. The stop induction switch 620 is arranged on the side of the basket mechanism 100, and the top and bottom of the column device 10 are respectively provided with stop induction pieces, which can be triggered when the stop induction switch 620 approaches the stop induction pieces. When the stop induction switch 620 is triggered, the control device 20 can control the basket mechanism 100 to stop ascending or descending.

[0078] With reference to the above Figure 6 The lifting device further comprises an initial position proximity switch 800. The initial position proximity switch 800 is arranged on the side of the basket mechanism 100, and the initial position proximity switch 800 can be triggered when the basket mechanism 100 descends to an initial position along the column device 10. When the initial position proximity switch 800 is triggered, the basket mechanism 100 can stop descending. In the embodiment, an initial position photoelectric device is arranged on the ground rail, and the initial position proximity switch 800 is a light-reflecting plate structure. When the basket mechanism 100 moves to the initial position, the initial position proximity switch 800 is located in the radiation range of the initial position photoelectric device, and at this time, the initial position proximity switch 800 can reflect the radiation emitted by the initial position photoelectric device.
