Description

Technical Field

[0001] This utility model relates to the technical field of industrial parts storage equipment, specifically a double-stroke telescopic parts rack automatic storage and retrieval device. Background Technology

[0002] In industrial production, the efficiency of parts storage and retrieval directly affects production continuity. To improve space utilization, factories commonly use multi-layer, multi-depth automated racking systems to store various parts, maximizing storage capacity through inner and outer layer partitioning. The inner layer of this type of racking is farther from the outer edge, while the outer layer is closer to the retrieval ports, creating a storage scenario with differentiated access distances between the inner and outer layers. This is suitable for the centralized management of small to medium batches of multi-specification industrial parts.

[0003] Traditional factories rely heavily on manual labor for parts storage and retrieval. While manual handling is relatively convenient for outer parts, it is labor-intensive and tiring due to repetitive tasks. For inner parts located far away, the outer parts must be moved first to access the inner items, which is cumbersome and time-consuming, seriously affecting the production cycle. In addition, manual handling is prone to damage to parts or carrier boxes due to positioning errors. Some automated storage and retrieval equipment uses a single-stroke telescopic structure, which can only cover the outer area of ​​the shelf and cannot reach the inner parts located far away. Manual assistance is still required to move the outer items, thus failing to achieve full-area automated storage and retrieval. Utility Model Content

[0004] The purpose of this invention is to provide a dual-stroke telescopic parts rack automatic storage and retrieval device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-stroke telescopic parts rack automatic storage and retrieval device, including a rack body, a drive assembly on the rack body, a first telescopic assembly on the rack body, a second telescopic assembly on the back of the first telescopic assembly, the drive assembly for driving the first telescopic assembly and the second telescopic assembly to perform telescopic movement, a bracket installed on the left side of the rack body, and a proximity switch installed on the bracket.

[0006] Optionally, the drive assembly includes a drive motor, the right end of the output shaft of the drive motor passing through the shelf body and extending into it, a drive gear being mounted on the surface of the output shaft of the drive motor, and two meshing first transmission gears being rotatably connected inside the shelf body, with the first transmission gear located at the top meshing with the drive gear.

[0007] Optionally, the shelf body has two driven gears rotatably connected inside. The driven gear at the top meshes with the drive gear, and the driven gear at the bottom meshes with the first transmission gear at the bottom. A first rack plate is installed on the back of the shelf body.

[0008] Optionally, the first telescopic assembly includes an upper fork plate, which is disposed on the back of the first rack plate, and a second rack plate that meshes with the two driven gears is installed on the front of the upper fork plate at a position corresponding to the two driven gears.

[0009] Optionally, the upper fork plate opening is rotatably connected to two transmission gears that mesh with the first rack plate, and the upper fork plate opening is rotatably connected to seven meshing second transmission gears, with the top transmission gear meshing with the top second transmission gear and the bottom transmission gear meshing with the bottom second transmission gear.

[0010] Optionally, first guide rails are installed on both the left and right sides of the front of the upper forklift plate, and several first guide sliders are installed on the back of the shelf body at positions corresponding to the first guide rails.

[0011] Optionally, the second telescopic assembly includes a lower fork plate disposed behind the upper fork plate. A third rack plate that meshes with two transmission gears is mounted on the front of the lower fork plate. Second guide rails are mounted on both the left and right sides of the front of the lower fork plate. A second guide slider that slides in contact with the second guide rails is mounted on the back of the upper fork plate at a position corresponding to the second guide rails.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves a dual-stroke telescopic function through a nested design of a first telescopic component composed of an upper fork moving plate and a second telescopic component composed of a lower fork moving plate. The first stroke extends from the first telescopic component, accurately covering the outer area of ​​the shelf. The second stroke extends further through the second telescopic component, reaching the inner distant area of ​​the shelf. Without the need for manual movement of the outer parts, automated storage and retrieval of the shelf across its entire depth range can be achieved, completely solving the problems of incomplete coverage and cumbersome manual operation of traditional single-stroke devices, and improving the utilization rate of storage space.

[0014] 2. The drive assembly of this utility model uses a single drive motor to provide power. Through the meshing transmission of the drive gear, the first transmission gear, and the driven gear, it synchronously drives the second rack plate of the first telescopic assembly and the third rack plate of the second telescopic assembly to move. No additional drive unit is required. The gear and rack transmission method has high transmission efficiency and no slippage. The seven meshing second transmission gears ensure uniform power transmission, making the operation of the two telescopic assemblies synchronous and smooth, avoiding telescopic jamming. Compared with the multi-motor drive structure, it is more compact and easier to maintain. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5A double-stroke telescopic parts rack automatic storage and retrieval device includes a rack body 1. Inside the rack body 1, a drive gear 22 is rotatably connected via bearings. The drive gear 22 transmits the rotational motion of a motor to a first transmission gear 23 and a driven gear 24 located at the top via meshing transmission. Inside the rack body 1, two meshing first transmission gears 23 are rotatably connected via bearings. The top first transmission gear 23 meshes with the drive gear 22. Driven gears 24 mesh with both the top of the drive gear 22 and the bottom of the bottom first transmission gear 23. The top first transmission gear 23 meshes with the drive gear 22, and the bottom first transmission gear 24 meshes with the drive gear 22. The transmission gear 23 meshes with the driven gear 24 at the bottom to realize the vertical transmission of power. The driven gear 24 is rotatably connected to the inside of the shelf body 1 through a rotating shaft. The driven gear 24 drives the second rack plate 32 of the first telescopic component 3 to move linearly through meshing. The drive motor 21 is bolted to the left side of the shelf body 1 and at the position corresponding to the drive gear 22. The right end of the output shaft of the drive motor 21 passes through the shelf body 1 and extends into its interior. The output shaft of the drive motor 21 is fixedly connected to the central shaft of the drive gear 22. The drive motor 21 provides the only power source. The output shaft drives the drive gear 22 to rotate, providing power for the telescopic movement of the double telescopic components.

[0023] A first rack plate 25 is bolted to the back of the rack body 1. The first rack plate 25 meshes with the transmission gear 33 inside the first telescopic assembly 3, providing a power transmission reference for the second telescopic assembly 4. An upper fork-moving plate 31 is provided on the back of the first rack plate 25. The upper fork-moving plate 31 adopts a fork-type structure, which is lightweight and has a strong load-bearing capacity, realizing the first stroke of extension and retraction, covering the outer area of ​​the rack. The opening of the upper fork-moving plate 31 is rotatably connected to two transmission gears 33 that mesh with the first rack plate 25. The transmission gears 33 mesh with the first rack plate 25 and the third rack plate 42 respectively, transmitting power to the second telescopic assembly 4. Using the fixed reference of the first rack plate 25, the linear motion of the upper fork-moving plate 31 is converted into its own rotational motion, thereby driving the second telescopic assembly 4 to extend and retract, realizing single-power extension and retraction. The dual-stroke linkage is ingeniously structured and highly efficient in transmission. The internal rotating connection of the upper fork plate 31 is connected to seven meshing second transmission gears 34. The top transmission gear 33 meshes with the top second transmission gear 34, and the bottom transmission gear 33 meshes with the bottom second transmission gear 34. By setting seven second transmission gears 34, the two transmission gears 33 are ensured to rotate synchronously, avoiding the offset of the second telescopic component 4 due to inconsistent speeds of the upper and lower transmission gears. This achieves uniform power distribution and improves transmission stability. A bracket 5 is installed on the left side of the rack body 1. A proximity switch 6 is installed on the bracket 5 at the position corresponding to the upper fork plate 31. The proximity switch 6 detects the extension and retraction position of the first telescopic component 3 in real time and sends a signal to the control system to control the start and stop of the drive motor 21.

[0024] A second rack plate 32, which meshes with the two driven gears 24, is bolted to the front of the upper fork plate 31 at the position corresponding to the two driven gears 24. The second rack plate 32 receives power from the drive assembly 2 and drives the upper fork plate 31 to extend and retract. First guide rails 35 are bolted to both the left and right sides of the front of the upper fork plate 31. Several first guide sliders 36 are installed on the back of the shelf body 1 at the position corresponding to the first guide rails 35. The first guide rails 35 slide in contact with the first guide sliders 36. The guide slider 36 and the upper fork plate 31 slide together to provide guidance for the extension and retraction of the upper fork plate 31. The drive motor 21, drive gear 22, first transmission gear 23, driven gear 24 and first rack plate 25 constitute the drive assembly 2, which is used to drive the first extension assembly 3 and the second extension assembly 4 to perform extension and retraction movements. The upper fork plate 31, second rack plate 32, transmission gear 33, second transmission gear 34, first guide rail 35 and first guide slider 36 constitute the first extension assembly 3, which is driven to perform extension and retraction movements by the drive assembly 2.

[0025] The back of the upper fork plate 31 is provided with a third rack plate 42 that meshes with the two transmission gears 33. The third rack plate 42 receives the power from the transmission gears 33 and drives the lower fork plate 41 to extend and retract. The lower fork plate 41 is bolted to the back of the third rack plate 42. The lower fork plate 41 and the upper fork plate 31 are nested together, and the extension and retraction strokes can be superimposed, greatly improving the storage and retrieval coverage. The fork-type structure is suitable for picking up and placing parts carrier boxes, ensuring the stability of the load. The left and right sides of the front of the lower fork plate 41 are... The upper fork plate 31 is equipped with a second guide rail 43. A second guide slider 44 is installed on the back of the upper fork plate 31 at a position corresponding to the second guide rail 43, and slides in contact with the second guide rail 43. The sliding cooperation between the second guide rail 43 and the second guide slider 44 provides guidance for the extension and retraction of the lower fork plate 41. The lower fork plate 41, the third rack plate 42, the second guide rail 43 and the second guide slider 44 constitute the second telescopic assembly 4. The first telescopic assembly 3 is driven to move by the drive assembly 2, thereby driving the second telescopic assembly 4 to perform telescopic movement.

[0026] When in use, the control system sends a signal to pick up or put down the outer layer, which drives the motor 21 to start rotating in the forward direction, and the output shaft drives the drive gear 22 to rotate.

[0027] The first telescopic component 3 extends: the drive gear 22 meshes and drives the top first transmission gear 23 and the top driven gear 24 to rotate, the bottom first transmission gear 23 synchronously drives the bottom driven gear 24, the double driven gear 24 meshes with the second rack plate 32, and drives the upper fork plate 31 to extend along the cooperation direction of the first guide rail 35 and the first guide slider 36;

[0028] When the proximity switch 6 detects that the upper fork plate 31 has extended to the preset outer layer travel threshold, it sends a signal to control the drive motor 21 to stop. The manual or matching clamping mechanism completes the picking and placing operation of the outer layer part carrier box. When the retraction signal is sent, the drive motor 21 reverses and the upper fork plate 31 retracts back to the initial position along the original path, completing one storage and retrieval cycle.

[0029] The control system sends a signal to pick up or put down the inner layer, which drives the motor 21 to start rotating forward and repeats the first telescopic component 3 extension step.

[0030] The second telescopic component 4 extends in conjunction: After the upper fork plate 31 extends to the outer travel threshold, the control system keeps the drive motor 21 working. The transmission gear 33 on the upper fork plate 31 meshes and rotates with the fixed first rack plate 25. The seven meshing second transmission gears 34 ensure that the two transmission gears 33 are synchronized, thereby meshing and driving the third rack plate 42, which in turn drives the lower fork plate 41 to extend further along the cooperation direction of the second guide rail 43 and the second guide slider 44.

[0031] When the contraction signal is sent, the drive motor 21 reverses, the lower fork plate 41 first retracts to the nested position of the upper fork plate 31, and then the upper fork plate 31 retracts to the initial position, completing one storage and retrieval cycle.
