Description

Technical Field

[0001] This utility model relates to the field of automated storage and retrieval systems (AS / RS) technology, and in particular to an AS / RS warning device. Background Technology

[0002] In automated warehouses, adjacent racking units form aisles, and forklifts need to enter and exit these aisles to transport goods.

[0003] When forklifts enter or exit aisle entrances / exits, there's a possibility that a person or other movable equipment might be passing through that area. Due to the blind spots created by the shelving, neither party may notice the other's passage, leading to a collision. This highlights a safety hazard at aisle entrances / exits. Existing forklifts are equipped with ultrasonic radar to detect obstacles in their path. However, this radar primarily detects obstacles on the ground, limiting its detection distance and angle. When the forklift is inside the aisle, the ultrasonic radar cannot detect people or movable equipment outside. Furthermore, as the forklift approaches the aisle, the shelving triggers the radar, and since people or movable equipment are moving, the ultrasonic radar cannot provide timely warnings. Therefore, in the above scenario, the forklift's ultrasonic radar cannot provide effective warnings.

[0004] To address these issues, at least one party needs to issue a warning when passing through the entrances and exits of the aisles to alert the other party and prevent collisions. The current solution involves forklifts sounding their horns when passing through the entrances and exits of the aisles to warn other vehicles passing by. However, noise interference within the automated storage and retrieval system can weaken or even drown out the horn's sound, making it difficult for other vehicles to hear the warning. Furthermore, multiple forklifts operating simultaneously in different aisles may sound their horns, making it difficult for other vehicles to distinguish whether the horns are from the entrances or exits of the aisles they are passing through. Additionally, multiple horns creating noise within the automated storage and retrieval system are ineffective in warning other vehicles.

[0005] Therefore, there is an urgent need for a three-dimensional warehouse warning device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a three-dimensional warehouse warning device to at least solve one of the above-mentioned problems.

The electro-generating component is disposed within the base, and the top cover is positioned on the base and connected to the pressure-receiving part of the electro-generating component. By pressing down on the top cover, the output terminal of the electro-generating component is triggered to generate electricity. The lifting component includes a handle that is rotatably disposed on the top cover. The handle has an embedded state and a lifted state. When the handle is in the embedded state, it is located within the top cover; when the handle is in the lifted state, it protrudes from the top cover. By rotating the handle, the handle can be switched between the embedded state and the lifted state.

[0010] The controller is connected to both the warning light and the output terminal of the power generation component, and is used to control the warning light according to the output signal of the power generation component.

[0016] Furthermore, the cover body also has a clearance cavity, which is connected to the fixing cavity, and the handle can be embedded in the clearance cavity.

[0017] Furthermore, the handle includes an integrally formed rotating connecting part and a lifting arc. The rotating connecting part is rotatably disposed within the rotating cavity, and the lifting arc is embedded in the clearance cavity, or the lifting arc protrudes from the fixing member.

[0018] Furthermore, the base has a receiving cavity that communicates with the positioning cavity.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a three-dimensional warehouse warning device including a warning light, a piezoelectric component, and a controller. The piezoelectric component includes a base, a top cover, a lifting component, and an electrification component. The base is embedded in the ground at the entrance and exit of the aisle. The warning light is located at the entrance and exit of the aisle. The electrification component is located inside the base. The top cover is positioned on the base and connected to the pressure-receiving part of the electrification component. By pressing down on the top cover, the output terminal of the electrification component is triggered to generate electricity. The controller can be connected to both the warning light and the output terminal of the electrification component to control the warning light according to the output signal of the electrification component. When a forklift passes through the entrance and exit of the aisle, it presses down on the top cover, which in turn presses down on the pressure-receiving part of the electrification component, thereby generating electricity. After receiving the signal of electricity generation, the controller controls the warning light to illuminate, thus reminding people passing through the entrance and exit of the aisle or the controller of mobile equipment to avoid the forklift, preventing collisions and reducing the frequency of safety accidents. The warning light does not generate noise inside the three-dimensional warehouse, avoiding noise pollution. When a forklift passes the piezoelectric component, the warning light for the corresponding aisle illuminates, clearly indicating to oncoming vehicles at the aisle entrances / exits that a forklift is approaching, thus serving as a warning. The lifting assembly includes a handle that rotates within the upper cover. The handle has two states: recessed and extended. When recessed, the handle is inside the upper cover; when extended, it protrudes from the upper cover. Rotating the handle switches between these two states. Under normal circumstances, the handle is recessed and does not obstruct forklift passage. When inspection or maintenance of the piezoelectric component is required, the handle can be rotated to protrude from the upper cover, and the upper cover can be removed from the base by pulling the handle, allowing for inspection and maintenance of the piezoelectric component within the base.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figures 1-7 As shown, this embodiment provides an automated warehouse warning device 100, which is installed inside the automated warehouse, specifically at the entrance / exit 301 of an aisle 300, which is formed by adjacent racking groups 200. When a forklift or a person passes through the entrance / exit 301 of the aisle 300, the automated warehouse warning device 100 will warn that a forklift is passing by, reminding the person passing by or the controller of the movable equipment to pay attention and avoid collision with the forklift, thereby improving the safety factor.

[0041] The automated storage and retrieval system warning device 100 includes a warning light 2, a piezoelectric component 1, and a controller 4. The piezoelectric component 1 includes a base 11, a top cover 12, a lifting component 13, and an electrification component 14. The base 11 is embedded in the ground at the entrance / exit 301 of the tunnel 300. The warning light 2 is located at the entrance / exit 301 of the tunnel 300. The electrification component 14 is located inside the base 11. The top cover 12 is positioned on the base 11 and is connected to the pressure-receiving part of the electrification component 14. By pressing down the top cover 12, the output end of the electrification component 14 is triggered to generate electricity. The controller 4 can be connected to the output ends of the warning light 2 and the electrification component 14 respectively, and is used to control the warning light 2 according to the output signal of the electrification component 14. When a forklift passes through the entrance / exit 301 of aisle 300, it presses down on the top cover 12. The top cover 12 then presses down on the pressure-receiving part of the electro-electric component 14, causing the electro-electric component 14 to generate electricity. Upon receiving the signal of electricity generation, the controller 4 activates the warning light 2. When the controller 4 no longer receives the signal, it deactivates the warning light 2, thus serving as a warning to passersby or operators of movable equipment to avoid the forklift and prevent collisions, reducing the frequency of accidents. The warning light 2 does not generate noise within the automated storage and retrieval system, avoiding noise pollution. When a forklift passes the piezoelectric component 1, the corresponding warning light 2 of aisle 300 illuminates, clearly indicating to oncoming vehicles passing through the entrance / exit 301 of that aisle 300 that a forklift is using, thus serving as a warning. The lifting assembly 13 includes a handle 132, which is rotatably mounted on the upper cover 12. The handle 132 has an embedded state and a lifted state. When the handle 132 is in the embedded state, it is located inside the upper cover 12; when the handle 132 is in the lifted state, it protrudes from the upper cover 12. Rotating the handle 132 switches between the embedded and lifted states. Under normal circumstances, the handle 132 is in the embedded state and does not obstruct the passage of the forklift. When inspection or maintenance of the piezoelectric assembly 1 is required, the handle 132 can be rotated to protrude from the upper cover 12, and by lifting the handle 132, the upper cover 12 can be removed from the base 11 for inspection and maintenance of the piezoelectric assembly 14 within the base 11. Figure 1 As shown, the warning light 2 is installed on the rack of the rack assembly 200 near the entrance / exit 301 of the aisle 300 so that forklifts or people entering or exiting can see the warning light 2 illuminate.

[0042] like Figures 2-5 As shown, the base 11 has a positioning cavity 111, and the cavity wall of the positioning cavity 111 has a positioning hole 112. The upper cover 12 includes a cover body 121 and a positioning post 123. The handle 132 is rotatably disposed on the cover body 121. The cover body 121 is provided with a positioning post 123, which is positioned in the positioning hole 112.

[0043] Specifically, a positioning post 123 is provided on the side of the cover body 121 facing the base 11. The positioning post 123 is positioned in the positioning hole 112, so that the cover 12 will not move on the horizontal plane in the positioning cavity 111.

[0044] Furthermore, there are multiple positioning posts 123, which are spaced apart on the cover body 121, and the positioning posts 123 are corresponding to the positioning holes 112 one by one.

[0045] Furthermore, the upper cover 12 also includes a crimping portion 122, which is integrally formed with the cover body 121 and is connected to the pressure-receiving portion of the power generation component 14. Specifically, the crimping portion 122 abuts against the pressure-receiving portion of the power generation component 14.

[0046] Furthermore, the crimping portion 122 is located at the center of the cover body 121, and the positioning posts 123 are respectively disposed on both sides of the crimping portion 122. In this embodiment, two rows of positioning posts 123 are respectively provided on both sides of the crimping portion 122 to prevent the cover 12 from shifting horizontally within the positioning cavity 111.

[0047] Furthermore, the base 11 has a receiving cavity 113, which is connected to the positioning cavity 111. The power generation component 14 is disposed in the receiving cavity 113, and the crimping part 122 extends into the receiving cavity 113 and is connected to the pressure-receiving part of the power generation component 14.

[0048] Furthermore, the power generation component 14 includes a first quartz wafer 141, a second quartz wafer 142, an insulating sleeve 143, a first electrode 144, and a second electrode 145. The first quartz wafer 141 and the second quartz wafer 142 are symmetrically arranged vertically within the receiving cavity 113. The working surfaces of the first quartz wafer 141 and the second quartz wafer 142 are directly opposite each other. The working surface of the first quartz wafer 141 is subjected to metal vapor deposition to form a metal film and to form the first electrode 144. The working surface of the second quartz wafer 142 is subjected to metal vapor deposition to form a metal film and to form the second electrode 145. The first electrode 144 and the second electrode 145 are directly opposite each other. The insulating sleeve 143 is sleeved on the first quartz wafer 141, the second quartz wafer 142, the first electrode 144, and the second electrode 145. The insulating sleeve 143 serves to provide insulation and positioning. When the top cover 12 is pressed, it will press down the first quartz crystal 141 and the second quartz crystal 142. After being subjected to force, the first quartz crystal 141 and the second quartz crystal 142 generate charges on the working surface, which are transmitted to the controller 4 through the first electrode 144 and the second electrode 145.

[0049] It should be noted that the piezoelectric component 1 operates based on the piezoelectric effect. When the first quartz crystal 141 and the second quartz crystal 142 are subjected to mechanical pressure, the internal charge distribution changes, resulting in a potential difference between the working surfaces of the first quartz crystal 141 and the second quartz crystal 142, thereby generating a current. As long as the pressure persists, this separation and accumulation of charge will continue, thus continuously generating electrical energy. Therefore, the controller 4 will only stop receiving the output signal of the power generation component 14 when the forklift leaves the piezoelectric component 1. In other words, before the forklift leaves the piezoelectric component 1, the controller 4 can continuously receive the output signal of the power generation component 14, and the controller 4 can control the warning light 2 to remain on during this period, meaning that the warning light 4 will remain on while the forklift passes through the piezoelectric component 1.

[0050] Furthermore, the power generation component 14 also includes a lead wire 147 and a lead-out end 146. One end of the lead wire 147 is connected to the first electrode 144 and the second electrode 145, and the other end is connected to the lead-out end 146. The lead-out end 146 is located outside the base 11 and is connected to the controller 4.

[0051] Furthermore, a lead hole 1431 is provided on the insulating sleeve 143, and a lead cavity 114 is provided on the base 11. The lead hole 1431 and the lead cavity 114 are connected, and the lead wire 147 is provided in the lead hole 1431 and the lead cavity 114.

[0052] Furthermore, the lifting assembly 13 also includes a fixing member 131, which is fixedly installed on the cover body 121. The fixing member 131 has a rotating cavity 1311, and the handle 132 is rotatably disposed in the rotating cavity 1311.

[0053] Furthermore, the cover body 121 has a fixing cavity 1211, and the fixing member 131 is fixedly installed in the fixing cavity 1211.

[0054] Furthermore, the cover body 121 also has a clearance cavity 1212, which is connected to the fixed cavity 1211, and the handle 132 can be embedded in the clearance cavity 1212. When the handle 132 is in the embedded state, the handle 132 is hidden in the rotating cavity 1311 and the clearance cavity 1212, so as not to affect the forklift passing over the cover 12.

[0055] Furthermore, the handle 132 includes an integrally formed rotating connecting part 1321 and a lifting arc 1322. The rotating connecting part 1321 is rotatably disposed in the rotating cavity 1311, and the lifting arc 1322 is embedded in the relief cavity 1212, or the lifting arc 1322 protrudes from the fixing member 131.

[0056] Furthermore, the lifting assembly 13 also includes a rotating shaft 133, which is fixedly installed in the rotating cavity 1311, and the rotating connection part 1321 is rotatably disposed on the rotating shaft 133.

[0057] like Figure 1 and Figure 6 As shown, the automated warehouse warning device 100 also includes a mounting assembly 5, through which the warning light 2 is mounted on the shelf. The mounting assembly 5 includes a first magnetic block 51 and a second magnetic block 52. The first magnetic block 51 is mounted on the warning light 2, and the second magnetic block 52 is configured to be mounted on the shelf at the entrance / exit 301 of the aisle 300. The first magnetic block 51 can be attracted to the second magnetic block 52. This magnetic connection method facilitates installation and allows for easy replacement of the warning light 2.

[0058] Furthermore, the mounting assembly 5 also includes a first mounting plate 53 and a second mounting plate 54, which are vertically arranged. The second magnetic block 52 is mounted on the first mounting plate 53, and the second mounting plate 54 is fixedly mounted on the shelf. Specifically, the second magnetic block 52 can be mounted on the first mounting plate 53 by adhesive bonding, and the first magnetic block 51 can be mounted on the bottom of the warning light 2.

[0059] Furthermore, mounting holes 541 are provided on the second mounting plate 54, and fasteners can be used to connect to the mounting holes 541 to fix the second mounting plate 54 on the shelf.

[0060] like Figure 7 As shown, the automated storage and retrieval system warning device 100 also includes an amplifier 3. The output end of the piezoelectric component 1 is a lead-out terminal 146, which is connected to the amplifier 3. The amplifier 3 is connected to the controller 4, and the controller 4 is connected to the warning light 2. The electrical signal from the lead-out terminal 146 is amplified by the amplifier 3 and transmitted to the controller 4. After receiving the electrical signal, the controller 4 controls the warning light 2 to illuminate, thereby achieving the purpose of warning.

[0061] Furthermore, a filter can be set between amplifier 3 and controller 4, so that the electrical signal amplified by amplifier 3 is filtered by the filter before being input into controller 4.

[0062] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
