Description

Technical Field

[0001] This utility model relates to the field of packaged grain storage, and more particularly to a three-dimensional rack storage system. Background Technology

[0002] After bulk grains are packaged in bags, they are stacked on pallets and then placed on corresponding automated storage and retrieval systems using shuttle vehicles, thus forming an automated storage and retrieval system. This system has many advantages, such as small footprint and high storage efficiency.

[0003] Existing automated storage and retrieval systems, such as Figures 1-2 As shown, it includes multiple three-dimensional shelving units 1 arranged at intervals along the left and right directions. Each three-dimensional shelving unit is provided with multiple pallet placement areas 2 arranged in the up and down directions. Each pallet placement area also includes multiple pallet placement areas 2 arranged sequentially in the front and back directions.

[0004] The automated storage and retrieval system (AS / RS) also includes a shuttle, which consists of a frame 6 capable of moving back and forth between two adjacent AS / RS racks. A forklift unit 5 is mounted on the frame 6, guided vertically. The forklift unit includes two forklift arms 4 capable of moving horizontally and vertically. In use, the two forklift arms move forward to grip the bottom of the corresponding pallet, then move upward to lift the pallet. The frame moves the pallet back and forth, and the forklift unit moves the pallet 3 vertically to the corresponding pallet placement area. Finally, the forklift arms move downward to place the pallet in the designated pallet placement area.

[0005] Pallets basically have two structural forms, one of which is as follows: Figure 2 As shown, the pallet includes an upper support 7 for contacting the packaging bag, and a pallet support is provided at the bottom of the support 7. The pallet support includes three pallet legs 8 spaced apart in the front-to-back direction, and a fork 9 is formed between two adjacent pallet legs for cooperating with the forklift arm.

[0006] Another type is... Figure 3 As shown, the pallet is an integral structure, including an upper support 7 for contacting the packaging bag, an integral pallet support at the bottom of the support 7, and forks 9 on the pallet support for cooperating with the forklift arm.

[0007] The existing automated racking system has the following problems: the support structure is a flat structure, and the pallet legs are placed directly on the flat structure of the support. In the event of an earthquake, the pallet is prone to horizontal displacement relative to the support. In other words, the earthquake resistance of the entire automated racking system is not strong. In particular, the overall height of the racking cabinet is relatively high, and it is very dangerous when the pallet at a high position is displaced. Utility Model Content

[0008] The purpose of this invention is to provide a squeeze-expanded support pile that can add metal support to the support plate.

[0009] To solve the above-mentioned technical problems, the technical solution of the automated racking storage system of this utility model is as follows:

[0010] An automated storage and retrieval system includes multiple rack cabinets spaced apart in the left-right direction. Each rack cabinet has multiple pallet placement areas arranged vertically. The system also includes pallets for placing at the bottom of the corresponding pallet placement area and a shuttle for moving the pallets. Each pallet includes a support portion and a pallet support at the bottom of the support portion. The pallet support has forks. The shuttle includes a forklift arm for engaging with the forks. The bottom of the pallet placement area has a support positioning groove for inserting the corresponding pallet support vertically. The opening of the support positioning groove is a guide opening that is wider at the top and narrower at the bottom. A support locking mechanism is provided between the support positioning groove and the corresponding pallet support for locking the pallet support and unlocking it when the pallet support moves out of the support positioning groove from bottom to top.

[0011] Furthermore, the supporting locking mechanism includes a locking pin that is guided and moved along the front-to-back direction and mounted on the automated rack cabinet. A locking pin return spring is provided between the locking pin and the automated rack cabinet. The locking pin return spring applies a force to the locking pin, causing the locking pin to have a tendency to move in the direction of the corresponding pallet support. The pallet support is provided with a locking pin hole corresponding to the locking pin. The locking pin has a locking end for extending into the locking pin hole. The upper end of the locking end is the upper unlocking slope of the locking pin, and the lower end of the locking end is the lower unlocking slope of the locking pin.

[0012] Furthermore, the bottom of the tray support is provided with a support unlocking ramp for engaging with the upper unlocking ramp.

[0013] Furthermore, the support locking mechanism includes a locking pin that is guided and mounted on the corresponding pallet support in the front-to-back direction. The groove wall of the support positioning groove is provided with a locking pin hole corresponding to the locking pin. A locking pin return spring is provided between the locking pin and the pallet support. The locking pin return spring applies a force to the locking pin, causing the locking pin to have a tendency to move towards the locking pin hole. An electromagnet is provided on the other side of the locking pin for energizing when the forklift arm contacts the bottom of the pallet.

[0014] Furthermore, a metal conductive plate is provided on the tray at the top of the fork, and the metal conductive plate is electrically connected to the electromagnet through a wire. A forklift conductive part is provided at the top of the forklift arm for contacting and conducting electricity with the metal conductive plate. A shuttle power supply is provided on the shuttle car to supply power to the forklift conductive part.

[0015] Furthermore, the voltage of the electromagnet is 24V, and the current is 50mA~300mA.

[0016] Furthermore, the pallet support includes three pallet legs spaced apart in the front-to-back direction, with forks formed between the pallet legs, and a support locking mechanism is provided on the automated racking system.

[0017] Furthermore, the pallet support includes three pallet legs spaced apart in the left-right direction, with fork openings formed between the pallet legs. The pallet is a one-piece structure, and locking pins are set on the pallet legs.

[0018] Furthermore, the fork opening is located between the bottom surface of the pallet support and the support portion, and the support locking mechanism is installed on the automated racking cabinet.

[0019] Furthermore, the fork opening is located between the bottom surface of the pallet support and the support portion, and the locking pin is set on the pallet support.

[0020] The beneficial effects of this utility model are as follows: When in use, the pallet legs are placed into the corresponding support positioning grooves from top to bottom. The guide opening, which is wider at the top and narrower at the bottom, facilitates the smooth entry of the pallet legs into the support positioning grooves. The support positioning grooves and the pallet legs are positioned at the upper limit in the horizontal direction, thus playing a certain role in shock absorption. At the same time, when the pallet legs enter the support positioning grooves, the support locking mechanism will lock the legs, thereby increasing the force between the pallet legs and the support positioning grooves. When it is necessary for the pallet legs to be moved out of the support positioning grooves from bottom to top, the support locking mechanism releases the locking of the pallet legs, and the pallet legs can be moved out smoothly from bottom to top.

[0038] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0039] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0040] Example 1 of the automated racking storage system of this utility model is as follows: Figures 5-8 As shown: It includes multiple three-dimensional shelving units 1 arranged at intervals along the left and right directions. Each three-dimensional shelving unit 1 is provided with multiple pallet placement areas 2 arranged in the up and down directions. Each pallet placement area also includes multiple pallet placement areas 2 arranged sequentially in the front and back directions.

[0041] The automated storage and retrieval system also includes a shuttle, which comprises a frame 6 capable of moving back and forth between two adjacent racking units. A forklift unit 5 is mounted on the frame, guided vertically. The forklift unit includes two forklift arms 4 capable of moving horizontally and vertically. In this embodiment, the vertical movement of the forklift arms is achieved through a lifting mechanism 10, which is a scissor lift mechanism; the horizontal movement of the forklift arms is achieved through a moving mechanism 11, which includes moving wheels and a moving wheel drive motor that drives the moving wheels horizontally. In use, the two forklift arms can move forward and fork against the bottom of the corresponding pallet. Then, the forklift arms move upward, lifting the corresponding pallet. The frame moves the pallet back and forth, and the forklift unit moves the pallet vertically to the corresponding pallet placement area. Finally, the forklift arms move downward to place the pallet in the corresponding pallet placement area. The pallet includes an upper support portion for contacting the packaging bag. At the bottom of the support portion are three pallet supports spaced apart in the front-to-back direction. Each pallet support consists of three pallet legs 8 spaced apart in the front-to-back direction, with forks 9 formed between adjacent pallet legs for cooperation with the forklift arms.

[0042] All of the above are existing technologies and will not be described in detail here.

[0043] The improvement of this utility model is as follows:

[0044] The bottom of the pallet placement area is provided with a support positioning groove 13 for the corresponding pallet legs to be inserted in the vertical direction. The opening of the support positioning groove 13 is a guide opening 14 that is larger at the top and smaller at the bottom. The width of the support positioning groove on the lower side of the guide opening 14 is adapted to the width of the corresponding pallet leg. A support locking mechanism is provided between the support positioning groove and the corresponding pallet leg for locking the pallet leg and unlocking it when the pallet leg moves out of the support positioning groove from bottom to top.

[0045] In this embodiment, the support locking mechanism includes a locking pin 18 that is guided along the front-rear direction to the corresponding pallet support leg. The support positioning groove has a locking pin hole 20 corresponding to the locking pin. A locking pin return spring 19 is provided between the locking pin 18 and the pallet support leg 8. The locking pin return spring 19 applies a force to the locking pin, causing the locking pin to have a tendency to move towards the locking pin hole. An electromagnet 21 is provided on the other side of the locking pin for energizing when the forklift arm contacts the bottom of the pallet.

[0046] A metal conductive plate 15 is provided on the tray at the top of the fork arm. The metal conductive plate 15 is electrically connected to the electromagnet 21 via a wire 12. A forklift conductive part 25 is provided at the top of the forklift arm for contacting and conducting electricity with the metal conductive plate. A shuttle power supply is provided on the shuttle car to supply power to the forklift conductive part. In this embodiment, the shuttle power supply consists of a battery 16 provided on the shuttle car, which is electrically connected to the forklift conductive part 25 via a flexible wire 17. The voltage of the electromagnet is 24V, and the current is 50mA~300mA.

[0047] In use, when the forklift arm needs to lift the pallet, the forklift arm inserts into the fork slot 9 at the bottom of the pallet. As the forklift arm moves upward, the conductive part 25 on the forklift arm contacts the metal conductive plate 15 at the bottom of the pallet, conducting electricity. When the electromagnet 21 is energized, it generates a magnetic force, causing the locking pin to move away from the locking pin hole. The locking pin retracts into the corresponding pallet support leg, releasing the locking of the pallet support leg. When the forklift arm disengages from the metal conductive plate at the bottom of the pallet, the electromagnet is de-energized. Under the action of the locking pin return spring, the locking pin extends out from the pallet support leg, and the end of the locking pin extends into the corresponding locking pin hole, locking the pallet support leg. This ensures the force between the pallet support leg and the support positioning groove, guaranteeing the stability of the pallet in an earthquake environment. When the forklift arm needs to move the pallet, the locking pin retracts, ensuring that the pallet can move normally.

[0048] Example 2 of an automated racking storage system Figures 9-11 As shown: The support locking mechanism includes a locking pin 18 that is guided and moved along the front-to-back direction and assembled on the automated rack cabinet. A locking pin return spring 19 is provided between the locking pin 18 and the automated rack cabinet. The locking pin return spring 19 applies a force to the locking pin, causing the locking pin to have a tendency to move in the direction of the corresponding pallet support leg 8. The pallet support leg is provided with a locking pin hole 20 corresponding to the locking pin. The locking pin has a locking end for extending into the locking pin hole. The upper end of the locking end is the upper unlocking slope 22 of the locking pin, and the lower end of the locking end is the lower unlocking slope 24 of the locking pin.

[0049] The bottom of the tray support leg is provided with a support leg unlocking ramp 23 for engaging with the upper unlocking ramp 22.

[0050] The shape of the locking pin hole 20 matches the shapes of the upper and lower unlocking ramps of the locking pin. That is, the upper wall of the locking pin hole is a ramp structure that contacts the upper unlocking ramp of the locking pin, and the lower wall of the locking pin hole is a ramp structure that contacts the lower unlocking ramp of the locking pin. In use, when the shuttle places the pallet from top to bottom into the corresponding pallet placement area, the pallet legs enter the corresponding support positioning groove. The unlocking ramp of the legs pushes against the upper unlocking ramp of the locking end, and the locking pin retracts. After the pallet legs are lowered into position, the locking end of the locking pin enters the locking pin hole under the action of the locking pin return spring, limiting the pallet legs to ensure the stability of the pallet during an earthquake. When the shuttle lifts the pallet from bottom to top, the lower wall of the locking pin hole engages with the lower unlocking ramp, the locking pin retracts, and the pallet legs can be smoothly pushed out of the support positioning groove.

[0051] Example 3 of an automated racking storage system Figures 12-13 As shown: The difference between Example 3 and Example 1 is that the pallet 3 in this example is an integral structure pallet, which is a block structure as a whole. The fork 9 on the pallet for cooperating with the forklift arm is located between the bottom surface of the pallet support and the support part.

[0052] The width of the support positioning groove 13 matches the width of the entire pallet 3. The locking pin 18 is arranged on the groove wall of the support positioning groove 13 on both sides of the pallet, and the locking pin hole that cooperates with the locking pin is located on the opposite side surface of the pallet.

[0053] Example 4 of an automated racking storage system Figures 14-15 As shown: The difference between Example 4 and Example 2 is that the pallet in this example is an integral structure pallet, which is a block structure as a whole. The fork 9 on the pallet 3 for cooperating with the forklift arm is located between the bottom surface of the pallet support and the support part.

[0054] The width of the support positioning groove 13 matches the width of the entire pallet 3. The locking pins 18 are located on opposite sides of the pallet support 26, and the locking pin holes that cooperate with the locking pins are located on the corresponding side groove walls of the support positioning groove 13.
