Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), specifically to an automated storage and retrieval system that facilitates the adjustment of stacking racks. Background Technology

[0002] In the field of tire storage, existing automated warehouses have many problems, affecting storage efficiency and space utilization.

[0003] Chinese Patent Publication No. CN202511273274.2 discloses a tire stacking machine, including a first transport line and a second transport line. The first transport line is a roller conveyor structure and includes a lifting and placement assembly located on the first transport line for positioning individual tire bodies; a support frame placed on the second transport line, with stacking fixtures on its upper surface; and a lifting and stabilizing assembly located on both sides of the second transport line to separate the lower surface of the support frame from the second transport line during tire stacking. By raising and lowering the movable frame and controlling the height of the connector, the lower surface of the support frame is lifted to detach from the upper surface of the second transport line. After detachment, the operation of the second transport line does not affect the stability of the stacking fixtures on the support frame, thereby improving the stability of tire stacking and preventing the second transport line from stopping, thus improving stacking efficiency. In the above patent, a forklift is used to transport a stack of tires as a whole and directly stack them for support during finished tire transfer. This method requires the tires to be repositioned after transportation, and a suitable storage space must be selected again according to the tire model and size. The operation is cumbersome, which not only increases the workload of transportation, but also makes the tires prone to damage due to repeated handling, affecting product quality.

[0004] Tires come in a variety of sizes and models, but traditional automated warehouses often have fixed storage spaces, making it difficult to precisely match different tire models. This leads to wasted stacking space during the stacking process, reducing warehouse space utilization and failing to fully realize the warehouse's storage potential. Furthermore, the stacking racks in existing automated warehouses are inconvenient to adjust, unable to quickly and accurately adjust the size and model of tires stored in different locations according to actual production needs. They also cannot make timely adjustments during tire transfer, reducing the warehouse's adaptability and operational efficiency. Summary of the Invention

The two ends of the spring are fixedly connected to the horizontal groove and the sliding plate, respectively. The second ratchet is fixedly mounted on the rotating plate and is slidably connected to the rotating rod. The sliding plate is provided with a transmission chamfer, and the locking device is provided with a chamfer contact block that abuts against the transmission chamfer.

[0010] Preferably, the self-weight locking device includes a base plate, a first hinge rod, and an ejection locking rod. The base plate is located at the bottom end of the outer frame. A vertical limiting rod is provided on the base plate, passing through the outer frame and sliding vertically therewith. A return spring is sleeved on the vertical limiting rod. The two ends of the return spring are fixedly connected to the outer frame and the base plate, respectively. One end of the first hinge rod is hinged to the bottom of the outer frame. The ejection locking rod is horizontally slidably mounted on the base plate. The other end of the first hinge rod is hinged to the end of the ejection locking rod. A first locking port for inserting the ejection locking rod is provided on the side of the storage space of the stacking bracket.

[0011] Preferably, the vertical limiting rod consists of a vertically set central rod and two end blocks slidably set at both ends of the central rod. Each end block is provided with a second hinge rod at the end near the central rod, and the ends of the two second hinge rods away from the end blocks are hinged. The central rod is fixedly connected to the base plate, and the end blocks located below are fixedly connected to the bottom of the outer frame. The storage space of the stacking bracket is provided with second locking ports at both the upper and lower ends for the end blocks to be inserted.

[0012] Preferably, a horizontally retractable support plate is provided below the transfer gripper to support the bottom of the partition, and the second locking device includes a vertically mounted vertical limit frame at the top of the outer side of the outer frame, and a support seat capable of supporting the bottom of the partition is installed on the vertical limit frame.

[0013] Preferably, a vertical sliding seat is installed on the vertical limiting frame, and the vertical sliding seat is slidably set on the vertical limiting frame. The support seat is hinged on the vertical sliding seat via a rotating shaft. A torsion spring connected to the vertical sliding seat is installed on the rotating shaft. A deflection drive plate is fixedly installed on the support seat, and the deflection drive plate is connected to the locking device in a transmission connection.

[0014] Preferably, a snap-fit ​​plate is installed on the vertical sliding seat. The snap-fit ​​plate is located between the vertical sliding seat and the outer frame.

The support frame is provided with a second insertion hole for locking the insertion rod.

[0015] Preferably, the locking device further includes a first transmission plate capable of driving the deflection drive plate to deflect and a second transmission plate capable of driving the snap-fit ​​plate to retract, and a top plate that fits against the second transmission plate is installed on the top of the snap-fit ​​plate.

[0016] The advantages of this invention compared to the prior art are: 1. In the operation of an automated warehouse, the internal structure of the stacking rack is divided into multiple storage spaces for transfer racks used to store tires. These transfer racks connect to, carry, transfer, and store tires. They can connect to newly manufactured tires, serving as a transitional carrier from production to storage. The transfer racks can move within the warehouse, transferring the carried tires to designated storage spaces on the stacking racks for storage, reducing the need for secondary placement after tire transfer. The bottom-up storage method, with tires stored on top and partitions on the upper level, ensures the transfer rack's overall center is slightly lower, exhibiting higher stability during automated transfer and storage. The self-weight locking device at the bottom of the transfer rack securely connects to the stacking rack using its own weight, requiring no additional operation. This simplifies the connection process between the transfer rack and the stacking rack, reduces manual operation costs, and improves the operational efficiency of the automated warehouse.

[0017] 2. The height of the partitions on the transfer rack is precisely adjustable, allowing the automated warehouse to flexibly adapt to the storage needs of tires of different sizes, effectively improving warehouse space utilization and reducing space waste. The transfer rack uses a locking device to drive a rotating rod, causing a threaded rod to screw into or out of the first insertion hole at different heights on the support frame, thus adjusting the partition height and fully utilizing the storage potential of the automated warehouse space. The four ends of the partitions are locked to the transfer rack via a first locking device, and the top of the outer frame has a second locking device for holding unused partitions, facilitating the storage and management of excess partitions. When certain partitions are not needed, they can be placed on the top of the outer frame and held in place by the second locking device, maintaining the neatness of the transfer rack structure and facilitating quick retrieval when needed, further optimizing the management and utilization efficiency of the transfer racks in the automated warehouse.

[0020] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-11 An automated storage and retrieval system (AS / RS) with adjustable stacking racks is shown, comprising a stacking support 1 and a transfer rack 2. The stacking support 1 has several storage spaces for the transfer rack 2. The transfer rack 2 consists of an outer frame 3 and several layers of partitions 4 with precisely adjustable height intervals. The partitions 4 are raised and lowered within the outer frame 3. The four ends of the partitions 4 are locked to the transfer rack 2 by a first locking device. The top of the outer frame 3 is provided with a second locking device for clamping unused partitions 4. The bottom of the transfer rack 2 is provided with a weight-locking device that can stably connect to the stacking support 1 by its own weight. The transfer rack 2 transfers tires to the partitions 4 through transfer grippers. An adaptive bearing space is formed between two adjacent partitions 4. A locking control device is installed on the transfer grippers. The locking control device is in transmission cooperation with the first locking device and the second locking device respectively. Limiting sliders 5 are installed on the side walls of the partitions 4. The outer frame 3 is provided with vertical limiting grooves 6 that slide in cooperation with the limiting sliders 5.

[0022] This invention provides an automated storage and retrieval system (AS / RS) with easily adjustable stacking racks. Existing technologies often encounter problems when stacking tires, as varying tire sizes and models make it difficult to match fixed storage spaces, leading to wasted stacking space and reduced warehouse utilization. During the transfer of finished tires, a forklift is typically required to move a stack of tires as a whole, usually using a direct stacking method. This method requires tires to be rearranged after transfer, and appropriate storage spaces must be selected based on tire size, causing inconvenience. This invention addresses this by dividing the stacking support 1 into several storage spaces for transfer racks 2. The transfer racks 2 connect to and transfer newly produced tires, carrying, transferring, and storing them. This solves the problems of inconvenient stacking rack adjustment and the inability of the transfer racks 2 to flexibly adapt to different storage needs in existing AS / RS. The transfer rack 2 consists of an outer frame 3 and several layers of adjustable-height partitions 4. The partitions 4 can rise and fall within the outer frame 3 and are locked to the outer frame 3 by a first locking device. A second locking device at the top of the outer frame 3 can hold unused partitions 4. A self-weight locking device at the bottom of the transfer rack 2 ensures a stable connection with the stacking support 1 based on its own weight. The transfer gripper is used to transfer the tire onto the partition 4. The locking device works in conjunction with the first and second locking devices to control the locking state of the partition 4. The limiting slider 5 on the side wall of the partition 4 slides in conjunction with the vertical limiting groove 6 of the outer frame 3 to ensure the stability of the partition 4's lifting and lowering.

[0023] This design allows for precise height adjustment of the partitions 4 on the transfer rack 2, flexibly adapting to the storage needs of tires of different sizes and improving warehouse space utilization. The first locking device ensures the partitions 4 remain fixed in position during operation, guaranteeing storage safety. The second locking device facilitates the storage management of unused partitions 4. The self-weight locking device allows for a stable connection between the transfer rack 2 and the stacking support 1 without additional operation, simplifying the operation process. The locking control device enables coordinated control of all locking devices, enhancing automation. The limit slider 5 and vertical limit groove 6 ensure smooth lifting and lowering of the partitions 4, preventing them from swaying and affecting storage.

[0024] The design of the stacking support 1 and the transfer frame 2 makes tire stacking and storage more precise and reasonable, improves space utilization, and allows for flexible adjustment of the size and model of tires stored in each position according to actual production and usage needs. It can also make adaptive adjustments during the tire transfer process, improving adaptability.

[0025] Rotating rods 7 are installed at both ends of the partition 4, near and away from the transfer clamping claws. Threaded insert rods 8 are threaded to both ends of the rotating rods 7. The threaded insert rods 8 slide against the side wall of the partition 4. Support frames 9 are provided at the four ends of the outer frame 3. First insertion holes 10 for inserting threaded insert rods 8 are evenly provided on the support frames 9 along the vertical direction. The locking device is connected to the rotating rods 7 in a transmission connection.

[0026] The partition 4 is driven by a locking device to rotate the rotating rod 7, causing the threaded insert rod 8 to screw in or out, inserting or disengaging into the first insertion holes 10 at different heights on the support frame 9, thereby adjusting the height of the partition 4. The engagement of the threaded insert rod 8 with the first insertion holes 10 on the support frame 9 ensures precise positioning of the partition 4's height, meeting the storage requirements of tires of different heights. The transmission connection between the rotating rod 7 and the locking device facilitates centralized control of the partition 4's height adjustment, improving adjustment efficiency and accuracy, and enabling the transfer rack 2 to more flexibly adapt to diverse storage needs. The automatic adjustment of the height distance between two adjacent partitions 4 facilitates the placement and storage of tires.

[0027] The locking device includes a drive gear 11 mounted on the transfer gripper and capable of rotation, a driven gear 12 fixedly mounted on the rotating rod 7 and capable of meshing with the drive gear 11, the two rotating rods 7 are connected by a synchronous belt 13, the partition 4 is also provided with a first ratchet disc 14 and a second ratchet disc 15, the first ratchet disc 14 is fixedly connected to the rotating rod 7, the second ratchet disc 15 can lock into the first ratchet disc 14, and the second ratchet disc 15 is elastically connected to the partition 4.

[0028] When locking the partition 4, the transfer gripper approaches the transfer frame 2 and presses the drive gear 11 against the driven gear 12, causing them to mesh. The drive gear 11 of the locking device rotates and meshes with the driven gear 12 on the rotating rod 7, driving the rotating rod 7 to rotate. The two rotating rods 7 are connected by a synchronous belt 13 to ensure that the two rotating rods 7 rotate synchronously. The first ratchet disc 14 is fixedly connected to the rotating rod 7, and the second ratchet disc 15 can lock into the first ratchet disc 14 and is elastically connected to the partition 4. When the drive gear 11 drives the rotating rod 7 to rotate, the synchronous belt 13 causes the two rotating rods 7 to move synchronously, adjusting the position of the threaded rod 8. After adjustment, the second ratchet disc 15 locks with the first ratchet disc 14 under elastic action to prevent the rotating rod 7 from rotating accidentally and to fix the height of the partition 4.

[0029] The rotating rod 7 is stably driven by gear meshing and synchronous belt 13, ensuring the consistency of adjustment at both ends of the partition 4. The locking engagement of the first ratchet disc 14 and the second ratchet disc 15 effectively prevents the height of the partition 4 from changing after adjustment, improves storage stability, and ensures that the partition 4 of the transfer frame 2 can be stably connected to the outer frame 3 under different working conditions, thereby reliably supporting the tires.

[0030] The partition 4 is also provided with a sliding plate 16, which is slidably disposed at the bottom of the partition 4. The partition 4 is provided with a horizontal slide groove for the sliding plate 16 to slide. A spring is provided inside the horizontal slide groove, and the two ends of the spring are fixedly connected to the horizontal slide groove and the sliding plate 16 respectively. The second ratchet plate 15 is fixedly mounted on the rotating plate and is slidably connected to the rotating rod 7. The sliding plate 16 is provided with a transmission chamfer 17, and the locking device is provided with a chamfer abutment block 18 that abuts against the transmission chamfer 17.

[0031] When the height of partition 4 needs to be adjusted, the locking device activates, and the chamfered contact block 18 pushes the transmission chamfer 17, causing the sliding plate 16 to slide within the horizontal groove against the spring force. This disengages the second ratchet disc 15 from the first ratchet disc 14, allowing the rotating rod 7 to rotate freely for partition 4 height adjustment. The cooperation between the locking device and the sliding plate 16 achieves automatic unlocking, improving adjustment efficiency. Simultaneously, the spring mechanism ensures that the second ratchet disc 15 automatically resets and locks with the first ratchet disc 14 after adjustment, enhancing the reliability and stability of the device.

[0032] The self-weight locking device includes a base plate 19, a first hinge rod 20, and an ejection locking rod 21. The base plate 19 is located at the bottom of the outer frame 3. A vertical limiting rod 22 is provided on the base plate 19, which passes through the outer frame 3 and slides vertically with it. A return spring 23 is sleeved on the vertical limiting rod 22. The two ends of the return spring 23 are fixedly connected to the outer frame 3 and the base plate 19, respectively. One end of the first hinge rod 20 is hinged to the bottom of the outer frame 3. The ejection locking rod 21 is horizontally slidably provided on the base plate 19. The other end of the first hinge rod 20 is hinged to the end of the ejection locking rod 21. A first locking port for inserting the ejection locking rod 21 is provided on the side of the storage space of the stacking bracket 1.

[0033] When the transfer frame 2 is placed on the stacking support 1, its own weight causes the outer frame 3 to press down. This, through the first hinge rod 20, drives the ejector locking rod 21 to slide horizontally, inserting it into the first locking slot to lock it to the stacking support 1. Simultaneously, the vertical limiting rod 22, under the action of the return spring 23, restricts the vertical displacement of the outer frame 3, ensuring a stable connection. The self-weight locking device utilizes the weight of the transfer frame 2 and the tires it carries to achieve locking, eliminating the need for an additional power source and reducing costs. The vertical limiting rod 22 and the return spring 23 enhance the stability of the connection between the transfer frame 2 and the stacking support 1, preventing the transfer frame 2 from shaking or shifting during storage and ensuring storage safety.

[0034] The vertical limiting rod 22 is composed of a vertically set central rod 24 and two end blocks 25 slidably set at both ends of the central rod 24. Each end block 25 is provided with a second hinge rod 26 at the end near the central rod 24. The ends of the two second hinge rods 26 away from the end blocks 25 are hinged. The central rod 24 is fixedly connected to the base plate 19. The end blocks 25 located below are fixedly connected to the bottom of the outer frame 3. The storage space of the stacking bracket 1 is provided with second locking ports at both the upper and lower ends for the end blocks 25 to be inserted.

[0035] When the transfer frame 2 is placed on the stacking support 1, its own weight causes the outer frame 3 to press down, while the base plate 19 in contact with the stacking support 1 remains stationary. The outer frame 3 and the base plate 19 shift relative to each other, causing the lower end block 25 to insert downwards into the second locking slot. Since the central rod 24 is fixedly connected to the base plate 19, the central rod 24 and the lower end block 25 shift relative to each other, causing the second hinge rod 26 to deflect. The second hinge rod 26 then causes the upper end block 25 to insert into the second locking slot above the stacking support 1, thus achieving the vertical locking function of the vertical limiting rod 22 on the transfer frame 2. This connection method ensures a stable connection between the transfer frame 2 and the stacking support 1, better supporting the weight of the tires on the transfer frame 2 and various external forces during storage, reducing the risk of displacement or tipping of the transfer frame 2, and improving the overall safety of the automated warehouse.

[0036] Below the transfer gripper is a horizontally extendable support plate for supporting the bottom of the partition 4. The second locking device includes a vertical limit frame 27 vertically installed at the top of the outer side of the outer frame 3, and a support seat 28 capable of supporting the bottom of the partition 4 is installed on the vertical limit frame 27.

[0037] When the upper partition 4 needs to be removed downwards, the bottom partition 4 is first supported by the support plate, making the partition 4 relatively stationary with respect to the outer frame 3. The support seat 28 is then released, releasing the locking of the bottom partition 4 without a tire. The position of the support seat 28 relative to the vertical limit frame 27 is then adjusted to raise it and clamp the upper partition 4 of the supported partition 4, keeping it stationary. At this point, the bottom partition 4 without a tire can move freely. The height can be adjusted according to the specific model of the tire to be carried. After adjustment, it is locked to the outer frame 3. This structure improves the efficiency of storing the partitions 4, allowing the number of partitions 4 to be removed to be adjusted according to the actual load. Furthermore, the partitions 4 are stored at the top, while the tires are stored from bottom to top. This storage method ensures that the overall center of the transfer frame 2 is slightly lower, improving the stability of the transfer frame 2 during transport and storage.

[0038] A vertical sliding seat 29 is installed on the vertical limiting frame 27. The vertical sliding seat 29 is slidably set on the vertical limiting frame 27. The support seat 28 is hinged on the vertical sliding seat 29 via a rotating shaft 30. A torsion spring 31 connected to the vertical sliding seat 29 is installed on the rotating shaft 30. A deflection drive plate 32 is fixedly installed on the support seat 28. The deflection drive plate 32 is connected to the locking device in a transmission connection.

[0039] When the height of the support 28 needs to be adjusted, the locking device inserts the deflection drive plate 32 to rotate the support 28 around the pivot 30, and the torsion spring 31 provides the restoring force. Simultaneously, the vertical sliding seat 29 can slide on the vertical limiting frame 27 to adjust the vertical position of the support 28 to accommodate partitions 4 of different heights. This process involves first supporting the next layer of partition 4 with the support plate, keeping it stationary, then releasing the support 28, and using the vertical sliding seat 29 to move the support 28 on the vertical limiting frame 27 by the height of one partition 4. After the vertical sliding seat 29 relocks, the support 28 supports the bottom of the upper layer of partition 4. This structure allows the support 28 to be flexibly adjusted to better adapt to the bearing requirements of partitions 4 of different heights, improving the versatility and adaptability of the second locking device. The torsion spring 31 ensures that the support 28 can stably maintain its position after adjustment, ensuring the secure clamping of the partition 4 and further improving the storage efficiency and security of the automated warehouse.

[0040] A snap-fit ​​plate 33 is installed on the vertical sliding seat 29. The snap-fit ​​plate 33 is located between the vertical sliding seat 29 and the outer frame 3. The snap-fit ​​plate 33 and the vertical sliding seat 29 are connected by a spring. An insertion rod 34 is installed on the snap-fit ​​plate 33. The support frame 9 is provided with a second insertion hole for locking the insertion rod 34.

[0041] Once the vertical sliding seat 29 is adjusted to the appropriate position, the locking plate 33, under the action of the spring, causes the insertion rod 34 to insert into the second insertion hole, locking the position of the vertical sliding seat 29, thereby fixing the height of the support seat 28 and ensuring that the support seat 28 stably supports the partition 4. The quick locking of the position of the vertical sliding seat 29 is achieved through the cooperation of the spring and the insertion rod 34 with the second insertion hole.

[0042] The locking device also includes a first transmission plate 35 capable of driving the deflection drive plate 32 to deflect and a second transmission plate 36 capable of driving the snap plate 33 to retract. The top of the snap plate 33 is fitted with a top plate 37 that fits against the second transmission plate 36.

[0043] The first transmission plate 35 of the locking device can drive the deflection drive plate 32 to deflect, thereby adjusting the rotation of the support 28. The second transmission plate 36 can drive the snap-fit ​​plate 33 to retract, causing the insertion rod 34 to disengage from the second insertion hole, facilitating the position adjustment of the vertical sliding seat 29. The top plate 37 of the snap-fit ​​plate 33 fits against the second transmission plate 36, facilitating the transmission of driving force by the second transmission plate 36. Through the unified control of the locking device, the coordinated operation of the deflection of the support 28 and the locking of the vertical sliding seat 29 is achieved.

[0044] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
