Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), and particularly to an automated AS / RS for hardware components and its usage method. Background Technology

[0002] With the rapid development of the hardware industry, the types of hardware parts are becoming increasingly diverse, with significant differences in size, ranging from small fasteners and connectors to large hardware components and molds. This places higher demands on the adaptability, automation level, and safety of warehousing equipment.

[0003] Currently, most of the existing warehousing equipment used for hardware parts is traditional flat warehouse or ordinary automated warehouse, which has many technical defects and cannot meet the diversified and efficient warehousing needs of hardware parts.

[0004] On the one hand, existing automated warehouse racks are mostly fixed structures with fixed cavity dimensions, making them unsuitable for storing both small standard-sized hardware and large extended-sized hardware. Setting up dedicated racks for different sizes of hardware would significantly increase storage space occupancy, raise storage costs, and result in low rack utilization. On the other hand, some adjustable racks have complex adjustment structures and are cumbersome to operate. More importantly, these adjustable racks typically require notches to adjust the cavity size, but opening these notches disrupts the original support structure, lacking effective auxiliary support mechanisms. In particular, the rack beams at the notches (corresponding to the front support bars in this solution) lose their original support, leading to a significant decrease in structural strength and making them prone to bending, deformation, or even breakage. Even if some racks are equipped with simple rotating covers, these only serve to cover the notches and cannot form a stable support structure after rotation, making them unable to withstand the weight of large extended boxes. Serious safety hazards exist both during and after adjustment, hindering safe and stable warehousing operations.

[0005] On the other hand, existing automated storage and retrieval mechanisms in automated warehouses suffer from insufficient adaptability. Most mechanisms can only handle single-sized boxes, failing to coordinate with the transfer needs of boxes of different sizes, resulting in low efficiency. Furthermore, existing racking and retrieval processes lack effective multi-parameter detection methods, only able to measure box weight and unable to monitor key parameters such as rack levelness and mechanism positioning in real time. When storing large, extended boxes, racking deviations and inadequate locking mechanisms can easily lead to box tilting and falling, impacting warehouse safety and stability. Especially after gaps are opened or rack support structures change, the inability to effectively detect the stability of the support at the gaps further exacerbates safety risks. Summary of the Invention

[0006] The purpose of this invention is to provide an automated storage and retrieval system for hardware components and its usage method, so as to solve the problems mentioned in the background art.

[0021] A method for using an automated storage and retrieval system (AS / RS) for hardware parts, the method comprising the following steps:

[0022] S1. Cargo box preparation: Select a suitable standard or extended cargo box according to the size and specifications of the hardware to be stored, and put the hardware into the corresponding cargo box;

[0023] S2. Shelf zoning layout: The shelving is divided into several independent storage columns along the horizontal direction. Each column includes multiple vertically stacked standard storage cavities. Weight sensors are installed in the load-bearing area of ​​the connecting strip of each layer and column. The weight sensors are used to collect the load-bearing pressure generated by the goods above the corresponding position.

[0024] S3. Standard Cargo Box Storage and Retrieval Operation: No need to activate the opening and closing components, keep the opening closed, start the conveyor and lifting equipment, the conveyor will move the lifting equipment and a single loading platform to the front position corresponding to the target standard storage cavity, the lifting equipment will lift the loading platform to the corresponding height, and push the standard cargo box onto the connecting strip to complete the storage by extending and retracting the loading platform's telescopic plate. When retrieving goods, simply reverse the operation.

[0025] S4. Preparation for storing and retrieving extended cargo boxes: When it is necessary to store extended cargo boxes, the opening and closing assembly is activated to control the retraction of the rotating cylinder, which pulls the rotating part to rotate backward, exposing the notch, so that two adjacent standard storage cavities are merged into an extended storage cavity, and the column corresponding to the merged area is recorded as column N; at this time, the position sensor is activated to detect the contact status between the arc block and the fixed part, and the contact status between the rotating part and the positioning plate in real time;

[0026] S5. Multi-column distance-weighted weighted weight detection and warehouse priority determination: Taking the layer directly above the gap as the detection center, and extending K columns to the left and right from column N as the center, the bearing pressure value of all storage columns is denoted as... ;

[0027] in, This is to store the column number. ;

[0028] Corresponding to N columns, Corresponding to the first column on the right of column N, The first column from the left of column N, exceeding The columns within the range are not included in the calculation;

[0029] Calculate the comprehensive load-bearing parameters according to the rule that the closer to column N, the greater the weight, and the farther from column N, the smaller the weight:

[0030]

[0031] Among them, weight With lateral distance The increase of is monotonically decreasing, and ;Will With preset safety threshold If the load-bearing capacity is met, the load-bearing capacity is deemed acceptable; when multiple storage cavity locations that can be combined and extended are present, the difference is calculated. Difference The larger the cavity, the higher its priority for use;

[0032] S6. Locking and Multi-parameter Detection: When the position sensor detects that the rotating part is in place, the support cylinder is activated, pushing the conical positioning rod into the positioning hole of the arc block to complete the locking. After the position sensor detects that the locking is in place, the level sensor is triggered to start, and the overall and local level of the front support bar, the rear support bar and the connecting profile are detected in real time.

[0033] S7. Extended cargo box access: Only when the overall load parameters are considered. When the levelness detected by the levelness sensor and the locking state detected by the position sensor both meet the preset thresholds, the extended storage cavity is deemed qualified. The two loading platforms then work together to place the extended box on the two telescopic plates. Through the linkage of the conveying and lifting equipment, the loading platforms are moved to the corresponding positions of the extended storage cavity. The telescopic plates extend synchronously, pushing the extended box onto the connecting strip to complete the warehousing. When retrieving goods, steps S4, S5, and S6 are repeated. After the inspection is qualified, the two loading platforms work together to pull the extended box back and transfer it to the retrieval point.

[0034] S8. Reset and Monitoring: After the goods are stored or retrieved, the opening and closing components are reset, the rotating parts close the notch, and the multi-parameter sensor detection components remain in standby mode to monitor the level of the shelf, the load of the goods and the position status of the support components and the opening and closing components in real time. If any abnormal parameters occur, an alarm will be triggered.

[0035] The technical effects and advantages of this invention are as follows:

[0036] 1. This automated storage and retrieval system (AS / RS) for hardware components utilizes a combination of notches, support components, and opening / closing mechanisms on the rack frame. A rotating cylinder pulls a rotating component to open the notch, creating an extended storage cavity. When the rotating component tilts, a support cylinder pushes a conical positioning rod into a positioning hole to lock it in place, effectively supporting the front support bar above the notch and preventing structural deformation. Combined with two loading platforms, it enables dual storage and retrieval modes for standard and extended cargo boxes, improving rack utilization.

[0037] 2. This automated storage and retrieval system (AS / RS) for hardware components is equipped with multi-parameter sensing and detection components: weight sensors on the connecting bars detect the load of the cargo boxes to prevent overloading; level sensors on the front and rear support bars and connecting profiles detect the levelness of the shelves after the opening is completed; position sensors at the arc blocks and positioning holes detect the positioning and locking status of the support components and opening / closing components. The multi-sensor linkage forms a closed-loop control, significantly improving warehouse safety and stability. Attached Figure Description

The position sensor is arranged at the arc block 143 and the positioning hole 145 to detect the fitting state of the arc block 143 and the locking state of the conical positioning rod 1531, so as to realize the detection of the position of the support component 14 and the opening and closing component 15.

[0080] A method for using an automated storage and retrieval system (AS / RS) for hardware parts, the method comprising the following steps:

[0081] S1. Cargo box preparation: Select the appropriate standard cargo box 5 or extended cargo box 6 according to the size and specifications of the hardware to be stored, and put the hardware into the corresponding cargo box;

[0082] S2. Shelf 1 zoning layout: Shelf 1 is divided into several independent storage columns along the horizontal direction. Each column includes multiple vertically stacked standard storage cavities. Weight sensors are installed in the load-bearing area of ​​the connecting strip 113 of each layer and column. The weight sensors are used to collect the load-bearing pressure generated by the goods above the corresponding position.

[0083] S3. Standard cargo box storage and retrieval operation: Without activating the opening and closing component 15, the notch 13 remains closed. Activate the conveyor 2 and the lifting device 3. The conveyor 2 moves the lifting device 3 and the single loading platform 4 to the front position corresponding to the target standard storage cavity. The lifting device 3 moves the loading platform 4 to the corresponding height. The standard cargo box 5 is pushed onto the connecting strip 113 by extending and retracting the telescopic plate 48 of the loading platform 4 to complete the storage. The operation is reversed when retrieving the goods.

[0084] S4. Preparation for storing and retrieving extended cargo box: When it is necessary to store extended cargo box 6, start the opening and closing assembly 15, control the rotating cylinder 151 to retract, pull the rotating part 141 to rotate backward, expose the notch 13, so that two adjacent standard storage cavities are merged into extended storage cavity, and the column corresponding to the merged area is recorded as column N; at this time, the position sensor is activated to detect the contact status of the arc block 143 and the fixing part 142 and the contact status of the rotating part 141 and the positioning plate 152 in real time;

[0085] S5. Multi-column distance-weighted weight detection and warehouse priority determination: Taking the layer directly above gap 13 as the detection center, the bearing pressure value of all storage columns within a range extending K columns to the left and right from column N is denoted as... ;

[0086] in, This is to store the column number. ;

[0087] Corresponding to N columns, Corresponding to the first column on the right of column N, The first column from the left of column N, exceeding The columns within the range are not included in the calculation;

[0088] Calculate the comprehensive load-bearing parameters according to the rule that the closer to column N, the greater the weight, and the farther from column N, the smaller the weight:

[0089]

[0090] Among them, weight With lateral distance The increase of is monotonically decreasing, and ;Will With preset safety threshold If the load-bearing capacity is met, the load-bearing capacity is deemed acceptable; when multiple storage cavity locations that can be combined and extended are present, the difference is calculated. Difference The larger the cavity, the higher its priority for use;

[0091] S6. Locking and Multi-parameter Detection: When the position sensor detects that the rotating part 141 is in place, the support cylinder 153 is activated, pushing the conical positioning rod 1531 into the positioning hole 145 of the arc block 143 to complete the locking. After the position sensor detects that the locking is in place, the level sensor is triggered to start, and the overall and local level of the front support bar 111, the rear support bar 112 and the connecting profile 12 are detected in real time.

[0092] S7. Extended cargo box access: Only when the overall load parameters are considered. When the levelness detected by the levelness sensor and the locking state detected by the position sensor both meet the preset thresholds, the extended storage cavity is deemed qualified. The two loading platforms 4 are then activated to work together to place the extended box 6 on the two telescopic plates 48. Through the linkage of the conveying equipment 2 and the lifting equipment 3, the loading platform 4 is moved to the position corresponding to the extended storage cavity. The telescopic plates 48 extend synchronously to push the extended box 6 onto the connecting bar 113 to complete the storage. When picking up goods, steps S4, S5, and S6 are repeated. After the inspection is qualified, the two loading platforms 4 work together to pull the extended box 6 back and transfer it to the picking point.

[0093] S8. Reset and monitoring: After the goods are stored or retrieved, the opening and closing component 15 is reset, the rotating part 141 closes the notch 13, the multi-parameter sensor detection component remains in standby state, and monitors the level of the shelf 1, the load of the goods and the position status of the support component 14 and the opening and closing component 15 in real time. If any parameter abnormality occurs, an alarm is triggered.

[0094] By setting a notch 13 on the front of the frame 11 of the shelf 1, and setting a support component 14 and an opening and closing component 15 inside the notch 13, the notch 13 can be quickly opened by using the rotating cylinder 151 of the opening and closing component 15 to pull the rotating part 141 to rotate, merging adjacent standard storage cavities into extended storage cavities. The storage space size can be switched without complicated operations. At the same time, after the rotating part 141 is rotated, it is tilted. With the support cylinder 153 of the opening and closing component 15, it pushes the conical positioning rod 1531 into the positioning hole 145 to lock. The tilted rotating part 141 can effectively support the front support bar 111 above the notch 13, replacing the original damaged support structure and preventing the front support bar 111 from bending, deforming, or breaking. With the two symmetrically arranged loading platforms 4, a dual mode of storing and retrieving standard boxes 5 individually and extended boxes 6 collaboratively can be realized. There is no need to set up a special shelf 1 for hardware of different sizes, which effectively reduces the storage space occupation, improves the utilization rate of the shelf 1, reduces storage costs, and ensures the structural stability of the shelf 1 after the notch 13 is opened.

[0095] A multi-parameter sensing and detection component is set up, including a weight sensor, a level sensor, and a position sensor. Each sensor is precisely deployed and has a clear division of labor to form a collaborative detection system: The weight sensor is installed in the load-bearing area of ​​the connecting strip 113, which can detect the load of the cargo box in real time, avoiding overloading that could damage the shelf 1 or cause the cargo box to fall, thus solving the limitations of existing single weight detection. The level sensor is embedded in the front support strip 111, the rear support strip 112, and the connecting profile 12. After the opening notch 13 is combined with the extended storage cavity, it can detect the overall and local level of the shelf 1 in real time, ensuring that the level accuracy of the shelf 1 meets the storage requirements of the extended cargo box 6. The position sensor is arranged at the arc block 143 and the positioning hole 145, which can accurately detect the position and locking status of the support component 14 and the opening and closing component 15, ensuring that the rotating part 141 is supported in place and the conical positioning rod 1531 is locked reliably, avoiding safety hazards caused by the mechanism not locking properly.

[0096] Example: This example demonstrates the operation of an automated storage and retrieval system (AS / RS) for hardware components. The specific steps are as follows:

[0097] S1. Cargo box preparation: Select a suitable extended cargo box 6 according to the size and specifications of the hardware to be stored, and neatly place the hardware inside the extended cargo box 6.

[0098] S2. Shelf 1 Zoning: Shelf 1 is divided into six independent storage columns (A, B, C, D, E, and F) along the horizontal direction. Each column has multiple vertically stacked standard storage cavities. Weight sensors are installed in the load-bearing area of ​​the connecting strips 113 in each column and layer to collect the load-bearing pressure generated by the goods above them. Shelf 1 has a multi-layer stacking structure; the load of goods on the upper layer is transmitted downwards along the supporting structure, generating an additional force on the lower notch 13. The load on higher layers is attenuated by the multi-layer structure, resulting in a minimal impact. In this embodiment, the layer containing notch 13 and the adjacent layer above it are selected as the main detection layers. In practical applications, the number of detection layers can be flexibly increased or decreased according to the total height of shelf 1, the stacking height of goods, and the on-site operating conditions. Setting the lateral detection range. That is, taking column N as the center, extending 2 columns to the left and 2 columns to the right to participate in the calculation, and no data is collected for columns outside this range.

[0099] S3. Standard Cargo Box Storage and Retrieval Operation: If a standard cargo box 5 is stored, the opening and closing component 15 will not be activated, and the notch 13 will remain closed. The weight sensor detects the bearing pressure above the storage compartment. After the detection is qualified, the conveyor equipment 2 and the lifting equipment 3, together with a single loading platform 4, complete the storage or retrieval operation of the standard cargo box 5.

[0100] S4. Preparation for storing extended cargo boxes: This operation requires storing 6 extended cargo boxes. Select columns C and D and merge them to form an extended storage cavity. Record this merged area as column N. The opening and closing assembly 15 is activated, controlling the rotary cylinder 151 to retract, pulling the rotating component 141 to rotate backward, exposing the notch 13; the position sensor detects the contact status of the arc block 143 and the rotating component 141 in real time, confirming that the mechanism has moved in place.

[0101] S5. Multi-column weighted pressure detection and position priority determination: Taking the area directly above gap 13 as the detection center, the comprehensive bearing pressure of the layer where gap 13 is located and the adjacent upper layer is collected. The collection range is N columns and two columns on each side. The pressure values ​​at each position are as follows:

[0102] N columns, directly above gap 13: ;

[0103] The first column from the left in column N: ;

[0104] The first column from the right of column N: ;

[0105] The second column from the left in column N: ;

[0106] The second column from the right in column N: ;

[0107] The above values ​​have taken into account the load effect of goods immediately above, and can accurately reflect the actual stress on gap 13 and the surrounding area. Weighting coefficients are set as follows: , , , , All weighting coefficients are greater than 0, and increase with horizontal distance. Increases monotonically and decreases.

[0108] According to the formula Calculate the overall bearing pressure:

[0109]

[0110] Preset safety threshold ,because The overall stress on gap 13 and its surrounding structure is determined to be within a safe range, and deformation or collapse due to excessive load is unlikely. When multiple locations within the system can be combined to form an extended storage cavity, the difference is calculated. The larger the difference, the more ample the current storage space's load capacity, and the higher the priority for using the extended storage cavity.

[0111] S6. Locking and Multi-parameter Detection: After the position sensor detects that the rotating part 141 is in place, the support cylinder 153 is activated, pushing the conical positioning rod 1531 into the positioning hole 145 of the arc-shaped block 143 to complete the mechanical locking. After the locking action is completed, the levelness sensor is activated to detect the overall and local levelness of the front support bar 111, the rear support bar 112, and the connecting profile 12.

[0112] S7. Extended Cargo Box Storage and Retrieval: After all three indicators—comprehensive load-bearing pressure, shelf levelness, and mechanism locking status—meet the preset requirements, the extended storage cavity is deemed qualified. The two loading platforms 4 are activated to work together to smoothly transfer the extended cargo box 6 into the extended storage cavity, completing the warehousing operation. For retrieval operations, the inspection and preparation steps from S4 to S6 are repeated. After passing the inspection, the extended cargo box 6 is retrieved and transferred by the two loading platforms working together.

[0113] S8. Reset and Monitoring: After the storage and retrieval of the cargo box is completed, the opening and closing component 15 resets, and the rotating component 141 resets and closes the notch 13. The multi-parameter sensing and detection component is continuously in standby monitoring mode, collecting the level of the shelf 1, the load pressure of each area, and the position signal of the mechanism in real time. Once the parameters exceed the preset range, an alarm is immediately triggered.

[0114] This solution, when detecting the stress in the area of ​​gap 13, simultaneously considers the load of goods on the layer containing gap 13 and the layer immediately above it, taking into account the characteristic of vertical load transmission downwards, effectively identifying the additional pressure caused by high-level goods stacking. Furthermore, the number of detection layers can be flexibly adjusted according to the actual height of shelf 1 and the goods stacking situation, making it more adaptable. Combining a method of limiting the number of detection columns laterally and using gradient weighted calculation, it ensures the accuracy of stress detection while controlling data acquisition and processing costs. Through comprehensive judgment based on bearing pressure, levelness, and multiple interlocking mechanical locking mechanisms, it effectively avoids risks such as deformation under pressure at gap 13 and tipping over of shelf 1, improving the operational safety and stability of the storage equipment.
