Description

Technical Field

[0001] This utility model relates to the field of intelligent logistics technology, and more specifically, to a logistics warehousing system. Background Technology

[0002] With the development of technology, intelligent warehousing and logistics are being used more and more widely in various industries. In terms of mechanical structure, it mainly involves automated storage and retrieval systems (AS / RS) and their supporting stacker cranes.

[0003] Traditional material inbound and outbound processes often rely on conveyor lines. While this method enables continuous material transport, in desktop-level small automated storage and retrieval systems (AS / RS), the presence of conveyor lines not only occupies a large area but also, due to the limitations of their overall structure, results in longer material inbound and outbound times, reducing the overall operational efficiency and flexibility of the warehousing system. Utility Model Content

[0006] Furthermore, the fork assembly includes: a support plate, a drive assembly drivenly connected to the support plate; a drive unit disposed on the support plate; and a movable plate disposed horizontally on the support plate, the movable plate being adjustable in size along the width direction of the rack, the drive unit being drivenly connected to the movable plate to drive the movable plate to move relative to the support plate.

[0007] Furthermore, the bottom of the support plate has an opening, and the drive unit is disposed at the opening and passes through the opening. The drive unit includes: a motor connected to the inner wall of the support plate at the opening, the extension direction of the drive end of the motor being the same as the length direction of the shelf; a gear connected to the drive end of the motor, the drive end driving the gear to rotate, the rotation axis of the gear being the same as the extension direction of the drive end; and a rack disposed horizontally on the moving plate, the extension direction of the rack being perpendicular to the rotation axis of the gear, the rack and the gear cooperating with each other to drive the moving plate to move closer to or away from the material inlet along the width direction of the shelf.

[0008] Furthermore, the movable plate includes: a first fork plate, movably disposed on a support plate along the width direction of the shelf, with a rack disposed on the side of the first fork plate facing the support plate to drive the first fork plate to move along the width direction of the shelf; and a second fork plate, movably disposed above the first fork plate, with the second fork plate moving in the same direction as the first fork plate, and the first fork plate being drivenly connected to the second fork plate via a transmission mechanism to drive at least a portion of the second fork plate to extend out of the first fork plate.

[0009] Furthermore, the transmission mechanism includes a first transmission member and a second transmission member. The first transmission member drives the second fork plate to move away from the feed opening along the width direction of the shelf, and the second transmission member drives the second fork plate to move towards the feed opening along the width direction of the shelf. The first transmission member and the second transmission member cooperate with each other to drive the second fork plate to extend out of the first fork plate.

[0010] Furthermore, the first transmission component has the same structure as the second transmission component. The first transmission component includes: a first connecting block and a second connecting block, the first connecting block being disposed on the support plate and the second connecting block being disposed on the second fork plate; a first pulley being disposed at one end of the first fork plate near the shelf; and a first transmission belt being wound around the outer periphery of the first pulley, one end of the first transmission belt being connected to the first connecting block and the other end of the first transmission belt being connected to the second connecting block.

[0011] Furthermore, the second fork plate, the first fork plate, and the support plate have the same dimensions along the width direction of the shelf; the second fork plate is provided with a connecting structure at both ends along the length direction of the shelf, and the connecting structure has two independently distributed slide grooves along the length direction of the shelf. The slide grooves extend along the width direction of the shelf, and the support plate is slidably connected to one of the slide grooves through a first rolling element, and the second fork plate is slidably connected to the other slide groove through a second rolling element.

[0012] Furthermore, the shelf includes a main body and multiple placement panels, which are spaced apart on the main body and form multiple placement cavities with the main body. The placement panels are used to place items. Multiple limiting posts are provided on the placement panels, and at least some items are located in the multiple limiting posts. The multiple limiting posts cooperate with each other to limit the position of the items on the placement panels.

[0013] Furthermore, the placement board is also equipped with magnetic attachments, which magnetically engage with the items to fix their position on the placement board.

[0014] Furthermore, the drive assembly includes a horizontal adjustment mechanism and a vertical adjustment mechanism.

Compared to the prior art, the material inbound and outbound processes often require the use of conveyor lines, which occupy a large area and, due to their overall structural limitations, result in long material inbound and outbound times. This application, through the above-mentioned layout, eliminates the need for conveyor lines. The rack directly connects to the AGV via a transfer device, making the overall system miniaturized. This not only saves the time spent transferring and transporting items on the conveyor line, but also improves the operational efficiency and flexibility of the entire warehousing system. It can adapt to the application needs of different site sizes and scenarios. The miniaturization of the overall system also facilitates visits and inspections by operators, making it convenient for practical course teaching. Attached Figure Description

[0030] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 7As shown, this embodiment of the present invention provides a logistics warehousing system, which includes: a rack 10, a transfer device 20, and an automated guided vehicle (AGV) 40. The rack 10 has multiple spaced placement cavities 101, each with a loading port 102 located on a side wall along the length of the rack 10. The transfer device 20 is located on the side of the rack 10 with the loading port 102. The transfer device 20 includes a fork assembly 21 and a drive assembly 22. At least a portion of the fork assembly 21 can extend into the loading port 102 to pick up and place items 01 within the placement cavity 101. The drive assembly 22 is motive-connected to the fork assembly 21 to drive the fork assembly 21 towards or away from the loading port 102. The drive assembly 22 can drive the fork assembly 21 to move between the rack 10 and the AGV 40. The AGV 40, the transfer device 20, and the rack 10 are distributed along the width of the rack 10.

[0032] By applying the technical solution of this utility model, the drive component 22 can directly drive the fork assembly 21 to approach or move away from the feed inlet 102 to remove the item 01 from the placement cavity 101 and place it on the automated guided vehicle 40; or transfer the item 01 on the automated guided vehicle 40 to the placement cavity 101 to achieve rapid retrieval and placement of the item 01. Compared with the prior art, the material entry and exit process often requires the use of a conveyor line, which occupies a large area and, due to its overall structural limitations, results in a long material entry and exit time. This application eliminates the conveyor line through the above layout. The rack 10 is directly connected to the automated guided vehicle 40 through the transfer device 20, making the overall system miniaturized. This not only saves the transfer and transportation time of the item 01 on the conveyor line, but also improves the operational efficiency and flexibility of the entire warehousing system. It can adapt to the application needs of different site sizes and scenarios. The miniaturization of the overall system also makes it convenient for operators to visit and inspect, and facilitates actual course teaching.

[0033] like Figure 3 As shown, the fork assembly 21 includes a support plate 211, a drive unit 212, and a movable plate. The drive unit 22 is drivably connected to the support plate 211 to move the support plate 211 between the rack 10 and the automated guided vehicle 40. The drive unit 212 is mounted on the support plate 211, and the movable plate is horizontally mounted on the support plate 211. The movable plate is adjustable in width along the rack 10. The drive unit 212 is drivably connected to the movable plate to move the movable plate relative to the support plate 211. This adjustable size of the movable plate not only accommodates items 01 of different sizes, improving the flexibility of transferring items 01, but also allows it to adapt to different distances between the transfer device 20 and the rack 10, enhancing the flexibility of the layout of the transfer device 20, the rack 10, and the automated guided vehicle 40.

[0034] like Figure 4 As shown, the bottom of the support plate 211 has an opening, and the drive unit 212 is disposed at the opening and passes through the opening. This reduces the space occupied by the drive unit 212 between the support plate 211 and the moving plate, thereby reducing the material required for processing the fork assembly 21. Furthermore, when the drive unit 212 is damaged or requires repair, it can be replaced through the opening without disassembling the entire fork assembly 21, making disassembly and maintenance very convenient. The drive unit 212 includes a motor 2121, a gear 2122, and a rack 2123. The motor 2121 is connected to the inner wall of the support plate 211 at the opening, and the extension direction of the drive end of the motor 2121 is the same as the length direction of the rack 10. The gear 2122 is driven by the drive end of the motor 2121, and the drive end drives the gear 2122 to rotate. The rotation axis of the gear 2122 is the same as the extension direction of the drive end. A rack 2123 is horizontally mounted on the moving plate. The extension direction of the rack 2123 is perpendicular to the rotation axis of the gear 2122. The rack 2123 and the gear 2122 cooperate to drive the moving plate to move closer to or away from the feed inlet 102 along the width direction of the rack 10. The motor 2121 drives the cooperation of the gear 2122 and the rack 2123, realizing the precise horizontal movement of the support plate 211, improving the positioning accuracy and handling efficiency of the fork assembly 21, and reducing operational errors.

[0035] like Figure 5 As shown, the movable plate includes a first fork plate 213 and a second fork plate 214. The first fork plate 213 is movably mounted on the support plate 211 along the width direction of the shelf 10. A rack 2123 is mounted on the side of the first fork plate 213 facing the support plate 211 to drive the first fork plate 213 to move relative to the support plate 211 along the width direction of the shelf 10. Specifically, it can move towards the shelf 10 or away from the shelf 10. The second fork plate 214 is movably disposed above the first fork plate 213. The moving direction of the second fork plate 214 is the same as that of the first fork plate 213. The first fork plate 213 is driven to the second fork plate 214 via a transmission mechanism, so as to drive at least part of the second fork plate 214 to extend out of the first fork plate 213. The arrangement of the second fork plate 214 increases the travel of the first fork plate 213, so that the fork assembly 21 can adapt to items 01 of different widths. The extension and retraction positions of the first fork plate 213 and the second fork plate 214 can be adjusted according to the width of the item 01 to ensure that the fork assembly 21 can accurately grasp and place the item. Through the cooperation of the first fork plate 213 and the second fork plate 214, the bidirectional extension and retraction of the moving plate is realized. This makes the distribution position of the automated guided vehicle 40, the transfer device 20 and the rack 10 more flexible. The automated guided vehicle 40 can be placed between the transfer device 20 and the rack 10, or it can be placed on the side of the transfer device 20 away from the rack 10.

[0036] like Figure 3 As shown, the transmission mechanism includes a first transmission component 215 and a second transmission component 216. The first transmission component 215 drives the second fork plate 214 to move away from the feed inlet 102 along the width direction of the shelf 10, and the second transmission component 216 drives the second fork plate 214 to move towards the feed inlet 102 along the width direction of the shelf 10. The first transmission component 215 and the second transmission component 216 cooperate with each other to drive the second fork plate 214 to extend beyond the first fork plate 213. By controlling the two movement directions of the second fork plate 214 separately through two sets of transmission components, the control logic of the entire transmission system can be simplified, the control difficulty can be reduced, and the response speed and reliability of the system can be improved.

[0037] Specifically, the first transmission component 215 and the second transmission component 216 have the same structure. The first transmission component 215 includes a first connecting block 2151, a second connecting block 2152, a first pulley 2153, and a first transmission belt 2154. The first connecting block 2151 is mounted on the support plate 211, and the second connecting block 2152 is mounted on the second fork plate 214. The first pulley 2153 is located at one end of the first fork plate 213 near the shelf 10. The first transmission belt 2154 is wound around the outer circumference of the first pulley 2153, with one end connected to the first connecting block 2151 and the other end connected to the second connecting block 2152. Compared to a direct mechanical connection, the combination of the transmission belt and pulley provides smoother operation during the movement of the second fork plate 214, reducing vibration and impact during movement, thereby improving the operational stability of the system and reducing the risk to goods during handling. Furthermore, by using the rotation of pulleys to drive the transmission belt, the friction at the direct contact points can be significantly reduced, thereby reducing the wear rate of mechanical parts. This not only extends the service life of the equipment and reduces maintenance costs, but also reduces noise.

[0038] The second fork plate 214, the first fork plate 213, and the support plate 211 have the same dimensions along the width direction of the rack 10, which further reduces the space occupied by the fork assembly 21, making the fork assembly 21 miniaturized. Both ends of the second fork plate 214 along the length direction of the rack 10 are provided with connecting structures 2141. Each connecting structure 2141 has two independently distributed grooves along the length direction of the rack 10, extending along the width direction of the rack 10. The support plate 211 is slidably connected to one of the grooves via a first rolling element 31, and the second fork plate 214 is slidably connected to the other groove via a second rolling element 32. The groove design guides the movement of the second fork plate 214, ensuring the stability of its movement. Simultaneously, the combined use of the groove and the rolling element significantly reduces friction and wear of the second fork plate 214 during movement, further improving the stability of its movement and reducing noise.

[0039] The first rolling element 31 and the second rolling element 32 can be a bearing or a roller structure. The first rolling element 31 is rotatably connected to the support plate 211 through a rotating shaft, and the second rolling element 32 is rotatably connected to the second fork plate 214 through a rotating shaft.

[0040] Furthermore, the shelf 10 includes a body 11 and a plurality of placement plates 12, which are spaced apart on the body 11. The placement plates 12 and the body 11 form a plurality of placement cavities 101, and the placement plates 12 are used to place items 01.

[0041] like Figure 6 As shown in one embodiment of this application, a plurality of limiting posts 121 are provided on the placement plate 12, and at least a portion of the item 01 is located within the plurality of limiting posts 121. The plurality of limiting posts 121 cooperate with each other to limit the position of the item 01 on the placement plate 12. The setting of the limiting posts 121 can ensure that the item 01 will not be displaced or tipped over on the placement plate 12 due to vibration or tilting during the handling process, which significantly improves the safety of goods during storage and handling.

[0042] Furthermore, the placement plate 12 is also equipped with magnetic components 122. Some items 01 are made of metal that can magnetically engage with the magnetic components 122. The magnetic components 122 magnetically engage with the items 01 to fix the position of the items 01 on the placement plate 12. The magnetic force of the magnetic components 122 enhances the fixing effect of the items 01 on the placement plate 12, improving the stability of the items 01 placed on the placement plate 12. At this time, the items 01 are placed horizontally.

[0043] In this application, the placement plate 12 can also hold the product 03, which includes the item 01 and the base 02. The item 01 is assembled on the base 02 to form the final product. At this time, the item 01 is a robotic arm model. The placement plate 12 can hold the item 01, the base 02, or the assembled product 03.

[0044] like Figure 7 As shown, in another embodiment of this application, the placement plate 12 is provided with one or more magnetic suction members 122, which magnetically engage with the base 02. The bottom of the base 02 is made of metal material that can magnetically engage with the magnetic suction member 122. At this time, the base 02 or the product 03 can be placed on the placement plate 12. The product 03 is placed vertically on the placement plate 12 through the base 02.

[0045] like Figure 1 and Figure 2As shown, the drive assembly 22 includes a horizontal adjustment mechanism 221 and a vertical adjustment mechanism 222. The fork assembly 21 is mounted on the vertical adjustment mechanism 222, which adjusts the displacement of the fork assembly 21 along the height direction of the rack 10. The horizontal adjustment mechanism 221 is positioned below the vertical adjustment mechanism 222 to provide support, and adjusts the displacement of the fork assembly 21 along the length direction of the rack 10. Through the cooperation of the vertical adjustment mechanism 222 and the horizontal adjustment mechanism 221, precise adjustment of the fork assembly 21 in three-dimensional space is achieved, ensuring that the fork assembly 21 accurately reaches every placement position on the rack 10, thus improving the accuracy and efficiency of goods storage and retrieval.

[0046] Specifically, the horizontal adjustment mechanism 221 includes a first linear motor, a first slide block 2211, and a first guide rail. The first guide rail extends along the length of the shelf 10, the first slide block 2211 slides against the first guide rail, and the first linear motor is driven by the first slide block 2211. The vertical adjustment mechanism 222 is mounted on the first slide block 2211. The vertical adjustment mechanism 222 includes a second linear motor, a second slide block 2221, and a second guide rail. The second guide rail extends along the height of the shelf 10, the second slide block 2221 slides against the second guide rail, and the second linear motor is driven by the second slide block 2221. The fork assembly 21 is mounted on the second slide block 2221. The linear motor directly generates linear motion and is driven by the slide block, enabling very precise positioning control. Whether along the length or height of the shelf 10, the position of the fork assembly 21 can be adjusted to the required precise coordinates, which greatly improves the accuracy of goods storage and retrieval. Both the horizontal adjustment mechanism 221 and the vertical adjustment mechanism 222 are existing technologies and will not be described in detail here.
