Description

Technical Field

[0001] This utility model relates to the field of cargo transfer technology, and in particular to a docking elevator. Background Technology

[0002] AGV (Automated Guided Vehicle) racks are commonly used for the storage and transfer of goods during transit. Unloading goods from these racks is primarily done manually, which is time-consuming, labor-intensive, and inefficient. To achieve automated unloading, a utility model patent (authorization announcement number: CN222041547U; application number: 2023236659726) discloses an AGV rack (such as...). Figure 1 Its working principle is as follows (see paragraph

[0039] of the instruction manual): After the shelf body 1 is connected to other shelves, the control linkage plate 52 (such as...) Figure 2 The control plate 5 rotates as it moves away from the ground. With the cooperation of the control plate 5 and the control block 41, the limit block 2 can slide towards the ground through the control rod 4 to release the restriction of the limit post 21 on the goods. Since the transmission frame 11 has a certain inclination, the goods slide down and get off the transmission frame 11 under the action of the transmission roller 111.

[0003] When the AGV cart rack is unloaded, its multiple layers of goods slide synchronously to the detachment conveyor frame 11, making it impossible to unload the multiple layers of goods onto the conveyor line in an orderly manner. Therefore, it is necessary to design a docking device that matches the AGV cart rack, so that the multiple layers of goods on the AGV cart rack can be unloaded onto the conveyor line in an orderly manner.

Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] like Figure 3As shown, a docking lift includes a frame 100, a loading platform mechanism 200, a lifting mechanism 300, a pressing mechanism 400, and a lifting drive mechanism 500. The loading platform mechanism 200 is slidably installed within the frame 100. The lifting mechanism 300 and the pressing mechanism 400 are both installed on the rear side of the bottom end of the frame 100. The lifting drive mechanism 500 is installed on the frame 100 to drive the loading platform mechanism 200 to perform lifting operations. Through the cooperative arrangement of the lifting mechanism 300 and the pressing mechanism 400, the AGV cart rack (such as...) can be... Figure 1 The multi-layered goods are automatically unloaded into the loading platform mechanism 200, and then the lifting drive mechanism 500 drives the loading platform mechanism 200 to rise and fall regularly, so that the multi-layered goods in the loading platform mechanism 200 are unloaded layer by layer in an orderly manner onto the conveyor line (not shown in the figure). Specifically, the top of the frame 100 is equipped with guardrails 700 around its perimeter, a protective ladder 800 is installed on the right side of the frame 100, and protective nets 900 are installed on the left and right sides of the frame 100 respectively.

[0034] like Figure 3 and Figure 6 As shown, the lifting mechanism 300 includes a lifting cylinder 310, a lifting plate 320, and lifting bolts 330. The cylinder body of the lifting cylinder 310 is mounted on the frame 100 with its drive end facing upward. The lifting plate 320 is horizontally mounted on the drive end of the lifting cylinder 310, and the lifting bolts 330 are vertically mounted on the left and right ends of the lifting plate 320, respectively.

[0035] like Figure 3 and Figure 6 As shown, the clamping mechanism 400 includes a clamping bracket 410 and a clamping bolt 420. The bottom end of the clamping bracket 410 is connected to the frame 100, and the clamping bolt 420 is vertically installed on the top of the clamping bracket 410. Specifically, there are two sets of clamping mechanisms 400, symmetrically arranged on the left and right sides of the lifting mechanism 300; the clamping bracket 410 is in the shape of a "7".

[0036] When the AGV cart rack moves to the rear of the frame 100, the clamping bolt 420 limits the rack body 1 of the AGV cart rack to prevent it from being lifted. The lifting cylinder 310 drives the lifting plate 320 to rise, and the lifting bolt 330 rises simultaneously to push the linkage plate 52 of the AGV cart rack (e.g., ...). Figure 2 It moves in a direction away from the ground, thereby realizing the automatic sliding of multiple layers of goods in the AGV cart rack into the loading platform mechanism 200.

[0037] like Figure 3 and Figure 8As shown, the loading platform mechanism 200 includes a platform 210, conveyor segments 220, blocking components 230, and guide components 240. The left and right ends of the platform 210 are slidably connected to the frame 100. The conveyor segments 220 are installed inside the platform 210 and are arranged in layers at intervals along the height of the platform 210. The blocking components 230 are located at the front end of the conveyor segments 220, and the guide components 240 are located in the middle of the conveyor segments 220. Specifically, each layer of conveyor segments 220 consists of two sets.

[0038] like Figure 8 and Figure 10 As shown, the conveyor segment 220 includes an electric roller 221, a driven roller 222, and a sprocket and chain assembly 223. The electric roller 221 is rotatably mounted on the front end of the frame 210, and the driven rollers 222 are rotatably mounted on the frame 210. There are several driven rollers 222, evenly distributed along the conveying direction of the conveyor segment 220. The electric roller 221 and the driven rollers 222 are connected by the sprocket and chain assembly 223. The conveyor segment 220 is prior art and will not be described in detail here.

[0039] like Figures 8-10 As shown, the blocking assembly 230 includes a blocking cylinder 231, a blocking plate 232, and a blocking post 233. The blocking cylinder 231 is located below the conveyor segment 220 with its drive end facing upwards. The blocking plate 232 is located between the electric roller 221 and the driven roller 222 adjacent to the electric roller 221, and its bottom end is connected to the drive end of the blocking cylinder 231. The blocking post 233 is vertically installed on the top of the blocking plate 232. The blocking assembly 230 prevents accidental drops of multi-layered goods from the AGV cart shelf into the loading platform mechanism 200. Before goods are unloaded from the AGV cart shelf, the blocking cylinder 231 drives the blocking plate 232 to rise, and the top of the blocking post 233 extends out of the conveyor segment 220. When the conveyor segment 220 transports goods, the blocking cylinder 231 drives the blocking plate 232 to descend and reset, and the top of the blocking post 233 retracts into the conveyor segment 220. Specifically, there are several blocking posts 233, which are evenly distributed along the length of the blocking plate 232.

[0040] like Figure 8 and Figure 10 As shown, the guide assembly 240 includes a guide rod 241 and a guide bracket 242. The guide rod 241 is positioned above the conveyor segment 220, and its length extends along the conveying direction of the conveyor segment 220. The guide rod 241 is connected to the platform 210 via the guide bracket 242. The guide assembly 240 guides the conveying of goods on the conveyor segment 220, preventing the goods from deviating.

[0041] like Figure 3 and Figure 4As shown, the lifting drive mechanism 500 includes a lifting assembly 510 and a drive assembly 520. The lifting assemblies 510 are respectively disposed at the left and right ends of the frame 100 and connected to the platform 210. The drive assembly 520 is installed at the top of the frame 100 to synchronously drive the two sets of lifting assemblies 510 to perform lifting movements.

[0042] like Figure 4 and Figure 5 As shown, the lifting assembly 510 includes a main sprocket 511, a driven sprocket 512, a balancing unit 513, an upper chain 514, and a lower chain 515. The main sprocket 511 is rotatably mounted on the top of the frame 100, and the driven sprocket 512 is rotatably mounted on the bottom of the frame 100. The front and rear ends of the balancing unit 513 are respectively rolledly connected to the frame 100 to reduce the coefficient of friction between the balancing unit 513 and the frame 100. One end of the upper chain 514 is connected to the top of the balancing unit 513, and its other end passes around the main sprocket 511 and connects to the top of the platform 210. One end of the lower chain 515 is connected to the bottom of the balancing unit 513, and its other end passes around the driven sprocket 512 and connects to the bottom of the platform 210. The balancing unit 513 is configured to pull the platform 210 up when lifting it, thereby reducing the energy consumption of the reduction motor 521 in the drive assembly 520. Specifically, the top of the frame 100 has a through hole for the upper chain 514 to pass through; the main sprocket 511 and the driven sprocket 512 are respectively located at the front and rear ends of the frame 100.

[0043] like Figure 4 and Figure 11 As shown, the drive assembly 520 includes a geared motor 521, a drive shaft 522, a main bevel gear 523, a drive shaft 524, and a driven bevel gear 525. The geared motor 521 is mounted at the top center of the frame 100. The drive shaft 522 is rotatably mounted at the top of the frame 100. There are two drive shafts 522, which are respectively located on the left and right sides of the geared motor 521. The output end of the geared motor 521 is connected to the drive shaft 522. The main bevel gear 523 is mounted at the end of the drive shaft 522 away from the geared motor 521. The drive shaft 524 is rotatably mounted at the top of the frame 100, and its front and rear ends are respectively connected to the main sprocket 511. There are two drive shafts 524, which are respectively located on the end side of the drive shaft 522 away from the geared motor 521. The driven bevel gear 525 is mounted in the middle of the drive shaft 524 and meshes with the main bevel gear 523.

[0044] When the platform 210 is raised or lowered, the geared motor 521 drives the two transmission shafts 522 to rotate synchronously, which in turn drives the main bevel gear 523 to rotate. Due to the meshing of the main bevel gear 523 and the driven bevel gear 525, the rotation of the main bevel gear 523 drives the drive shaft 524 to rotate through the driven bevel gear 525, which in turn drives the main sprocket 511 to rotate. The rotation of the main sprocket 511 drives the platform 210 to rise or fall through the upper chain 514.

[0045] like Figure 7 As shown, buffers 600 are respectively installed at the left and right ends of the frame 100. The buffers 600 are installed at the top and bottom ends of the frame 100, respectively, and correspond to the left and right ends of the platform 210. By setting the buffers 600, rigid collisions between the loading platform mechanism 200 and the frame 100 are avoided during the lifting process, thereby improving the service life.

[0046] During operation, when the AGV cart shelf moves to the rear of the frame 100, the lifting cylinder 310 is activated, and the goods on the AGV cart shelf are automatically unloaded onto the conveyor sections 220 of each layer; then the blocking cylinder 231 is activated, and the top of the blocking column 233 retracts into the conveyor section 220, and the electric roller 221 in the lower conveyor section 220 rotates, and all the goods on this conveyor section 220 are transported to the conveyor line in an orderly manner; then the reduction motor 521 is activated, the platform 210 is lowered by one layer, and the electric roller 221 in the middle conveyor section 220 rotates, and all the goods on this conveyor section 220 are transported to the conveyor line in an orderly manner; finally, the platform 210 is lowered by one more layer, and the electric roller 221 in the upper conveyor section 220 rotates.

[0047] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
