Description

Technical Field

[0001] This utility model relates to the field of warehousing technology, and in particular to an intelligent three-dimensional storage rack that is easy to schedule. Background Technology

[0002] Storage racks are storage devices based on six basic functions: packaging, transportation, loading and unloading, sorting, and logistics information management. With the continuous development of e-commerce, intelligent logistics technology and demand are also increasing. In intelligent logistics, intelligent storage racks are often used to temporarily store goods.

[0003] Traditional racking and picking methods have the following technical drawbacks: high risk of goods damage: rigid grippers / forks make rigid contact with goods, which can easily scratch the packaging; the gripping points are concentrated on the edge of the goods, and the goods are prone to tilting or slipping due to inertia during handling. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an intelligent three-dimensional warehouse rack that is easy to schedule.

[0005] The technical solution of this utility model, an intelligent automated storage rack that is easy to schedule, includes:

[0006] The outer frame of the shelf has one or more vertical partitions on its inner side. The inner side of the multiple areas separated by the vertical partitions on the inner side of the shelf frame is provided with comb plates arranged side by side. Multiple comb holes are equally spaced on the front side of the comb plates.

[0007] A sliding frame is slidably installed on the front side of the outer frame of the shelf. A first sliding seat is connected to the upper end of the sliding frame. The first sliding seat is slidably installed on the upper end of the outer frame of the shelf. A power component for driving the first sliding seat to move is installed on the upper end of the outer frame of the shelf.

[0008] The lifting seat is vertically slidably mounted on a sliding frame, and a four-rope synchronous winch for driving the lifting seat to rise and fall is installed at the upper end of the sliding frame.

[0009] The second sliding seat is slidably mounted on the lifting seat, and the lifting seat is equipped with an electric push rod for driving the second sliding seat to move.

[0010] A first belt conveyor and a second belt conveyor are both mounted on a second sliding seat.

[0011] Preferably, a clamping mechanism is installed on the second sliding seat. The clamping mechanism includes a second servo motor, a gear, two racks, and two clamping rods. The second servo motor is installed on the second sliding seat, the gear is connected to the output shaft of the second servo motor, the two racks are slidably installed on the second sliding seat and are meshed with the gear, and the two clamping rods are respectively connected to the outer ends of the two racks.

[0012] Preferably, the power assembly includes a first servo motor and a first threaded rod. The first servo motor is mounted on the outer frame of the shelf, the first threaded rod is connected to the output shaft of the first servo motor, and the first sliding seat is threadedly connected to the first threaded rod.

[0013] Preferably, a first infrared ranging sensor for detecting changes in the position of the first sliding seat is installed at the end of the outer frame of the shelf; and a second infrared ranging sensor for detecting changes in the position of the lifting seat is installed at the top of the sliding frame.

[0014] Preferably, it also includes a camera mounting bracket and a camera mounted on the camera mounting bracket, wherein the camera mounting bracket is mounted on a lifting base or a second sliding base.

[0015] Preferably, the belt widths of both the first and second belt conveyors are smaller than the width of the comb teeth holes.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This technical solution utilizes a three-dimensional motion mechanism to drive the first and second belt conveyors to precisely insert into the gaps at the bottom of the goods. Replacing traditional grippers or forks, the belts lift the goods smoothly and move them horizontally out. This method has the following significant advantages: 1. The two belts provide a wide support surface, evenly bearing the weight of the goods and effectively preventing tilting, shaking, or damage during handling. This is especially beneficial for fragile goods or goods with uneven bottoms, offering high stability. 2. The belts and goods are driven by surface contact friction, unlike the point or line contact of grippers, greatly reducing the risk of pinching the goods. 3. The entire handling process is highly automated, with smooth, continuous movements, enabling rapid inbound and outbound operations. Attached Figure Description

[0021] Example 1

[0022] like Figures 1-3 As shown in the figure, the intelligent three-dimensional warehouse rack proposed in this embodiment is easy to schedule, including rack outer frame 1, sliding frame 2, lifting seat 3, second sliding seat 10, first belt conveyor 11 and second belt conveyor 12.

[0023] One or more vertical partitions 5 are provided on the inner side of the outer frame 1 of the shelf. The inner side of the multiple areas separated by the vertical partitions 5 on the inner side of the outer frame 1 of the shelf is provided with comb plates 4 side by side. Multiple comb holes 401 are equidistantly opened on the front side of the comb plate 4.

[0024] The sliding frame 2 is slidably installed on the front side of the outer frame 1 of the shelf. The upper end of the sliding frame 2 is connected to the first sliding seat 7, which is slidably installed on the upper end of the outer frame 1 of the shelf. The upper end of the outer frame 1 of the shelf is equipped with a power component for driving the first sliding seat 7 to move. The power component includes a first servo motor 81 and a first threaded rod 82. The first servo motor 81 is installed on the outer frame 1 of the shelf, and the first threaded rod 82 is connected to the output shaft of the first servo motor 81. The first sliding seat 7 is threadedly connected to the first threaded rod 82. The end of the outer frame 1 of the shelf is equipped with a first infrared ranging sensor 91 for detecting the position change of the first sliding seat 7.

[0025] The lifting seat 3 is vertically slidably mounted on the sliding frame 2. A four-rope synchronous winch 6 for driving the lifting seat 3 to rise and fall is installed at the upper end of the sliding frame 2. A second infrared ranging sensor 92 for detecting changes in the position of the lifting seat 3 is installed at the top of the sliding frame 2.

[0026] The second sliding seat 10 is slidably mounted on the lifting seat 3, and the lifting seat 3 is equipped with an electric push rod 13 for driving the second sliding seat 10 to move; the first belt conveyor 11 and the second belt conveyor 12 are both mounted on the second sliding seat 10; the belt width of the first belt conveyor 11 and the second belt conveyor 12 is smaller than the width of the comb tooth hole 401.

[0027] This technical solution also includes a camera mounting bracket 18 and a camera 19 mounted on the camera mounting bracket 18. The camera mounting bracket 18 is mounted on the lifting seat 3 or the second sliding seat 10.

[0028] The working principle of this technical solution is as follows:

[0029] Initial state and goods storage: The goods are placed horizontally on the comb plates 4 on each layer of the shelf. The comb plates 4 have multiple longitudinal comb holes 401 evenly spaced on the front side. Part of the bottom of the goods is suspended above the comb holes 401. The shelf is mainly composed of a sturdy shelf frame 1. The interior is divided into multiple independent storage areas by one or more vertical partitions 5. Each area has comb plates 4 installed side by side to support the goods.

[0030] Picking instruction issuance and initial positioning: The warehouse management system (WMS) or PLC controller receives the picking instruction, specifying the specific layer height and horizontal position of the goods to be retrieved. First, the power unit is activated to drive the first sliding seat 7 to move along the upper end of the shelf frame 1. The horizontal movement of the first sliding seat 7 will drive the entire sliding frame 2 to slide horizontally along the front side of the shelf frame 1 until the sliding frame 2 moves to the front of the column where the target goods are located. The first infrared ranging sensor 91 installed at the end of the shelf frame 1 monitors the position change of the first sliding seat 7 in real time, providing a precise horizontal position to ensure accurate positioning. This ensures that the center lines of the first belt conveyor 11 and the second belt conveyor 12 installed on the lifting seat 3 are aligned with the corresponding comb holes 401 on the comb plate 4 below the target goods.

[0031] Vertical positioning and lifting: After the sliding frame 2 is positioned to the target column, the control system starts the four-rope synchronous winch 6 installed on the upper end of the sliding frame 2. The four-rope synchronous winch 6 drives the lifting seat 3 to move up and down along the vertical track on the sliding frame 2 by winding and unwinding the steel wire rope. The lifting seat 3 is raised or lowered to below the comb plate 7 where the target goods are located. The second infrared ranging sensor 92 installed at the top of the sliding frame 2 detects the position change of the lifting seat 3 in real time and provides accurate vertical height value feedback.

[0032] The picking mechanism extends and inserts into the toothed slots: After the lifting seat 3 reaches the target height, the telescopic rod of the electric push rod 13 pushes the second sliding seat 10 to move inward toward the shelf. The first belt conveyor 11 and the second belt conveyor 12 are fixedly installed on the second sliding seat 10. Therefore, as the second sliding seat 10 moves, the first belt conveyor 11 and the second belt conveyor 12 move together toward the depth of the shelf and the bottom of the goods. It should be noted that the belt width of the first belt conveyor 11 and the second belt conveyor 12 is smaller than the width of the comb hole 401. This allows the belts of the two belt conveyors to be accurately inserted into the two adjacent comb holes 401 below the goods. Finally, the belts of the first belt conveyor 11 and the second belt conveyor 12 will pass through the comb hole 401 and move to the bottom of the goods.

[0033] Lifting and removing goods from their storage locations: Restart the four-rope synchronous winch 6. The four-rope synchronous winch 6 drives the lifting seat 3, together with the second sliding seat 10, the first belt conveyor 11, and the second belt conveyor 12, to make a small upward lifting motion. As the lifting seat 3 moves upward, the belts of the first belt conveyor 11 and the second belt conveyor 12 lift the goods. Then, the first belt conveyor 11 and the second belt conveyor 12 start working. The two belt conveyors run synchronously in the same direction, and the goods are smoothly transported from their storage locations to the outside until the goods are completely removed from the internal space of the shelf and suspended in the area of ​​the lifting seat 3 in front of the sliding frame 2.

[0034] The picking mechanism retrieves and hands over the goods: After the goods are completely removed from the storage location, the electric push rod 13 pulls the second sliding seat 10 to move outward from the shelf, i.e., away from the shelf, thereby driving the first belt conveyor 11 and the second belt conveyor 12 and the goods they carry to exit from the comb hole 401 and return to the main area of ​​the lifting seat 3. It should be added that the camera 19 is installed on the camera mounting bracket 18, and the camera mounting bracket 18 can be installed on the lifting seat 3 or the second sliding seat 10. During this process, the status and position of the goods can be identified and monitored to assist in positioning or to detect anomalies.

[0035] Cargo lowering and transfer: The control system controls the four-rope synchronous winch 6 to drive the lifting seat 3 to descend, lowering the cargo to a low position for easy operation. After reaching the low position, the first belt conveyor 11 and the second belt conveyor 12 can be restarted to directly transport the cargo to the waiting AGV trolley, conveyor belt or manual operation area to complete the unloading and transfer of the cargo.

[0036] Example 2

[0037] like Figure 2 and Figure 3As shown in the figure, this embodiment proposes an intelligent three-dimensional storage rack that is easy to schedule. Compared with the first embodiment, in this embodiment, a clamping mechanism is installed on the second sliding seat 10. The clamping mechanism includes a second servo motor 14, a gear 17, two racks 16 and two clamping rods 15. The second servo motor 14 is installed on the second sliding seat 10. The gear 17 is connected to the output shaft of the second servo motor 14. The two racks 16 are slidably installed on the second sliding seat 10 and are meshed with the gear 17. The two clamping rods 15 are respectively connected to the outer ends of the two racks 16.

[0038] In this embodiment, a clamping mechanism is installed on the second sliding seat 10. The mechanism is driven by the second servo motor 14 to rotate the gear 17. When the gear 17 rotates, the two racks 16 will make linear movements in opposite directions or back directions, thereby causing the two clamping rods 15 fixed at the outer end of the racks 16 to open or close. During the process of the goods being lifted by the belt conveyor and moved out of the cargo position, the clamping rods 15 can close, which can realize the correction of the goods and also clamp and fix the goods to prevent the goods from accidentally tipping over or slipping during movement or waiting.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
