Detailed implementation manner

[0021] The following will describe the embodiments of the present invention in detail with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "first", "second", etc. indicate the orientation or position or sequential relationship based on the orientation or position or sequential relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0023] The present invention provides a material picking and placing mechanism for a bridge-type lifting and stacking system, including a bridge support 1 and a fork crossbeam 2; the fork crossbeam 2 is movably arranged on the bridge support 1, and the fork crossbeam 2 is driven by a first driving device to move up and down along a first direction; a fork mechanism 3 for picking and placing goods is arranged on the fork crossbeam 2, and the fork mechanism 3 is driven by a second driving device 4 to move forward and backward along a second direction. Specifically, in the actual application of the material picking and placing mechanism of this embodiment, the specific action process is that first, the fork crossbeam 2 is driven by the first driving device to descend to a level position adapted to the object goods to be picked and placed, the second driving device 4 drives the fork mechanism 3 to extend out below the object goods, and then the fork crossbeam 2 rises and the fork mechanism 3 retracts to move the object goods onto the fork crossbeam 2, completing the extraction of the object goods. The process of lowering the object goods is opposite to its extraction process. When the fork crossbeam 2 carrying the object goods descends to the level where the goods need to be stacked and stops, then the second driving device 4 drives the fork mechanism 3 to extend forward so that the object goods are located on the established storage level of the stacking shelf. At this time, the fork crossbeam 2 continues to descend a certain distance to place the object goods on the stacking shelf, and the fork mechanism 3 retracts and resets to complete the lowering operation of the object goods, and the next round of material picking and placing operations can be carried out. The present invention is a material picking and placing mechanism for large and heavy goods. Through the bridge-type lifting structure formed between the bridge support 1 and the fork crossbeam 2, it has a large picking and placing weight and is particularly suitable for the application and construction of a stacking system for large and heavy goods.

[0024] As an implementation manner, the object goods in this embodiment are stored in a cuboid cargo frame. To ensure the stability of the support for the cargo frame, the forklift mechanism 3 in this embodiment specifically includes a plurality of telescopic forks 30 spaced on the forklift crossbeam 2, that is, a plurality of spaced support points are formed in the length direction of the cargo frame to form an effective and stable support for it. It should be noted that although the forklift mechanism 3 shown in the drawings in this embodiment is a split structure, this is not the only limitation on the setting of the forklift mechanism 3 of the present utility model. In specific practical applications, it can be adaptively set according to the characteristics of the picking and placing of the actual object goods. That is, it is feasible for these spaced forklift mechanisms 3 to adopt an integral structure or a split structure, and it is also feasible for the telescopic forks 30 to be arranged at equal intervals or unequal intervals.

[0025] In a preferred implementation manner, the telescopic fork 30 can adopt a telescopic rod structure, and an anti-slip sticker 302 is arranged on the telescopic rod 301. For example, as shown in the drawings, in this embodiment, the telescopic fork 30 is specifically a segmented telescopic rod 301, where the frontmost telescopic rod 301 is the part that directly contacts the object goods (or the cargo frame). As described above, the material picking and placing mechanism in this embodiment is specifically designed for large and heavy goods. To achieve this function, the corresponding support components (such as the telescopic rod 301 in this embodiment) need to have sufficient strength. The support components can usually be made of steel materials or alloy materials. Generally speaking, the support components of these materials are strong enough to achieve the support function, but the materials are smooth and easy to wear. Therefore, in this embodiment, an anti-slip sticker 302 is attached to this section of the telescopic rod 301. The anti-slip sticker 302 can be made of a rougher wear-resistant and anti-slip material to increase the frictional resistance between the telescopic rod 301 and the object goods (or the cargo frame). On the one hand, the picking and placing action process is not easy to slide relatively, which is safer and more reliable. On the other hand, it can also increase the flexible buffer between the two, avoid direct contact wear between rigid components, avoid scratching and scuffing, improve the service life, and facilitate the maintenance and replacement of the forklift mechanism 3.

[0026] Specifically, in this embodiment, as shown in the drawings, a plurality of mounting ears 5 are arranged on the forklift crossbeam 2 corresponding to the telescopic forks 30, and the telescopic forks 30 are mounted on the mounting ears 5. It is easy to understand that based on the setting of the material picking and placing mechanism in this embodiment, the above-mentioned first direction is actually the up and down direction, and the above-mentioned second direction is actually the horizontal direction. By setting the telescopic forks 30 to be mounted on the mounting ears 5, on the premise of ensuring that the telescopic forks 30 meet the travel requirements for picking and placing goods, the horizontal width of the forklift crossbeam 2 can be minimized as much as possible, avoiding material waste and reducing equipment costs.

[0027] As a feasible implementation manner, as shown in the attached drawings, in this embodiment, the second driving device 4 includes a driving motor 401 and a transmission rod 402. The driving motor 401 drives the telescopic fork 30 to act synchronously through the transmission rod 402, and the driving motor 401 is arranged at the middle position of the transmission rod 402. As described above, the fork mechanism 3 of this embodiment is a split structure, specifically including a plurality of telescopic rods 301. To realize the synchronous telescopic movement of the plurality of telescopic rods 301, the driving motor 401 and each telescopic rod 301 of this embodiment are in meshing transmission with the transmission rod 402. By controlling the forward and reverse rotation of the driving motor 401, the synchronous extension and synchronous retraction of each telescopic rod 301 can be driven. The driving motor 401 is preferably arranged at the middle position of the transmission rod 402 to minimize the transmission torque at both ends of the transmission rod 402 and reduce the power requirement for the driving motor 401.

[0028] In this embodiment, as shown in the attached drawings, a U-shaped groove 6 is formed on the fork cross beam 2. The driving motor 401 and the transmission rod 402 are arranged in the U-shaped groove 6, and the U-shaped groove 6 is covered by a sealing plate 7. In this way, the relevant electrical components of the second driving device 4 such as the driving motor 401 and the transmission rod 402 can be embedded in a relatively enclosed chamber area. On the one hand, the structure of the fork cross beam 2 can be made more compact and concise, reducing the occupied space. On the other hand, these electrical components can be effectively protected from being easily damaged, and dust accumulation is also avoided, ensuring the service life and operation safety of the electrical components.

[0029] As a feasible implementation manner, the first driving device includes a winch arranged on the top of the bridge support 1 and a pulley assembly 8 arranged on the fork cross beam 2. The winch drives the fork cross beam 2 to move up and down along the first direction through the pulley assembly 8. In this way, through the specific combination of the winch and the pulley assembly 8, a relatively labor-saving driving structure can be formed, ensuring the driving force on the fork cross beam 2, improving the maximum load-bearing capacity of the material picking and placing mechanism, and making it more suitable for the operation of picking and placing large and heavy goods described in the present invention.

[0030] Preferably, in this embodiment, an anti-sway mechanism 9 is further arranged between the fork cross beam 2 and the bridge support 1. The anti-sway mechanism 9 is provided to reduce the sway of the fork cross beam 2 and the bridge support 1 during the specific movement process, so that the material picking and placing mechanism of this embodiment has better practical application effects in some implementation manners where the bottom of the bridge support 1 is suspended.

[0031] Feasibly, referring to the attached Figure 4As shown, in this embodiment, the anti-sway mechanism 9 includes a crossbeam track chute 901 formed on the bridge support 1 and a limit wheel provided on the end face of the forklift crossbeam 2. More specifically, in this embodiment, the limit wheel includes a first limit wheel 902 and a second limit wheel 903. The first limit wheel 902 abuts against the bottom surface of the crossbeam track chute 901, and the second limit wheel 903 abuts against the two side surfaces of the crossbeam track chute 901. In this way, in the horizontal direction at the left and right ends of the forklift crossbeam 2, the left and right ends of the forklift crossbeam 2 are restricted by the bridge support 1, reducing the sway of the forklift crossbeam 2 in this direction; in the horizontal direction at the front and rear ends of the forklift crossbeam 2, the front and rear ends of the forklift crossbeam 2 are also restricted by the bridge support 1, also reducing the sway of the forklift crossbeam 2 in this direction, thereby achieving the above-mentioned effect of reducing sway and ensuring the positioning accuracy of the material picking and placing mechanism when performing the material picking and placing action.

[0032] The above description is only for the preferred embodiments of the present invention, but it should not be construed as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to vary. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
