Description

Technical Field

[0001] The utility model relates to the technical field of storage, handling and access devices, in particular to a shuttle. Background Art

[0002] Automated warehouses are widely used in various fields, with stacker cranes playing a key role as the most important handling and retrieval equipment. Stacker cranes can perform automated handling and precise positioning, significantly improving logistics efficiency, reducing resource waste, and lowering production management costs.

[0003] Existing stackers typically require ground-mounted tracks, with a running mechanism driving the main frame along the tracks. This places certain load-bearing requirements on the surface on which the tracks are laid, and the tracks also require fixing and leveling with expansion bolts, making installation complex. Furthermore, existing stackers require a large overall footprint, and because the tracks are laid on the ground, the running mechanism can be easily blocked by debris that falls onto the tracks, impacting the stacker's normal operation.

[0050] like Figure 1-22 As shown, in one embodiment of the present invention, a shuttle is provided, comprising a main frame 100, a fork mechanism 200, a lifting mechanism 300, a first guide rail 400, a second guide rail 500, and a traveling mechanism 600. The fork mechanism 200 and the lifting mechanism 300 are both mounted on the main frame 100, and the lifting mechanism 300 is used to drive the fork mechanism 200 to move up and down along the height direction of the main frame 100. The first guide rail 400 and the second guide rail 500 are used to be mounted on a shelf, with the second guide rail 500 located below the first guide rail 400, and a busbar 700 is mounted on the second guide rail 500. The traveling mechanism 600 is used to drive the main frame 100 to move along the first guide rail 400, wherein the traveling mechanism 600 includes a first support frame 601, a friction drive wheel 602, a first traveling wheel assembly, a first driving member 603, an adjustable clamping assembly, and a second traveling wheel assembly 605.

[0051] The first support frame 601 is mounted on the main frame 100. The first travel wheel assembly, first driver 603, and adjustable clamping assembly are all mounted on the first support frame 601. The first travel wheel assembly cooperates with the top surface of the first guide rail 400. The first driver 603 vertically slides on the first support frame 601 via a first sliding assembly 613 and is in transmission connection with the friction drive wheel 602, which is located below the first guide rail 400. The adjustable clamping assembly is used to apply elastic force to the first driver 603 to press the friction drive wheel 602 against the bottom surface of the first guide rail 400. The second travel wheel assembly 605 is mounted on the main frame 100 and cooperates with the second guide rail 500.

[0052] The shuttle disclosed in this embodiment is designed with a first guide rail 400, a second guide rail 500, and a running mechanism 600. After the first guide rail 400 and the second guide rail 500 are installed on the shelf, the running mechanism 600 can drive the main frame 100 to move along the first guide rail 400, and the lifting mechanism 300 can drive the fork mechanism 200 to move up and down. In this way, there is no need to lay additional tracks on the ground to support and guide the main frame 100, which reduces the space occupied by the ground area, makes the overall structure more compact, and does not require the ground to be damaged during installation, so existing shelves can be modified on-site. At the same time, by designing the friction drive wheel 602 below the first guide rail 400 and utilizing the adjustable function of the adjustable clamping assembly, the friction drive wheel 602 can be made to adhere closely to the bottom surface of the first guide rail 400, and the driving friction force can be flexibly adjusted, thereby improving the driving effect on the main frame 100 and the stability of the shuttle during operation.

[0053] In one embodiment, the adjustable pressing assembly includes a second support frame 604, a pressing block 606, a mounting seat 607, and an elastic member 609. The second support frame 604 is fixed to the first support frame 601 and is located above the first driving member 603. The pressing block 606 is located on the side of the second support frame 604 facing away from the first driving member 603. The mounting seat 607 is fixed to the first driving member 603 and is located below the second support frame 604. Two guide rods 608 are provided on the mounting seat 607. The guide rods 608 are movable vertically through the second support frame 604 and the pressing block 606. The guide rods 608 are provided with a limit portion 610, which is used to prevent the pressing block 606 from separating from the guide rods 608. There are two elastic members 609 , which are springs. Each elastic member 609 is sleeved on a corresponding guide rod 608 . The elastic members 609 respectively abut against the pressing block 606 and the second support frame 604 , and the elastic members 609 apply an upward elastic force to the pressing block 606 .

[0054] Under the elastic force of the two elastic members 609, an upward elastic force is applied to the pressing block 606. Since the pressing block 606 is restricted by the limiting portion 610 on the guide rod 608, the pressing block 606 will cause the two guide rods 608, the mounting seat 607 and the first driving member 603 to have an upward movement trend. The first driving member 603 will press the friction driving wheel 602 tightly against the bottom surface of the first guide rail 400, thereby ensuring the contact effect between the friction driving wheel 602 and the first guide rail 400, and can also flexibly adjust the driving friction force.

[0055] In one embodiment, the friction drive wheel 602 is positioned near one end of the first support frame 601. The first travel wheel assembly includes two first wheels 611, one of which is positioned near the friction drive wheel 602 and the other is positioned away from the friction drive wheel 602. The travel drive mechanism also includes a second wheel 612, which is positioned below the first guide rail 400 and abuts against the bottom surface of the first guide rail 400. The cooperation of the friction drive wheel 602, the second wheel 612, and the two first wheels 611 ensures the stability of the movement of the first support frame 601 and the main frame 100.

[0056] In one embodiment, the shuttle further includes a busbar 700 disposed on the second guide rail 500. The busbar 700 is disposed on the second guide rail 500 and can provide power to devices on the shuttle. A second running wheel assembly 605 is disposed on the second guide rail 500 and is connected to the main frame 100.

[0057] In one embodiment, the fork mechanism 200 includes a carrier 201, a telescopic drive mechanism 202, and a fork arm mechanism. The carrier 201 has a first opening 2011 and a second opening 2012 for cargo to enter and exit. Fixed support plates 2013 are respectively provided on both sides of the carrier 201. Two fork arm mechanisms are provided between the two support plates 2013. Each fork arm mechanism is installed on the inner side of the corresponding support plate 2013 (i.e., on the side wall of the support plate 2013 facing the other support plate 2013).

[0058] Among them, the fork arm mechanism includes a first guide plate 203, a second guide plate 204, a third guide plate 205, a first follower assembly, a second follower assembly and two hook material assemblies 206. The first guide plate 203 is movably arranged on the inner side of the support plate 2013, the second guide plate 204 is movably arranged on the inner side of the first guide plate 203, the third guide plate 205 is movably arranged on the inner side of the second guide plate 204, and the two hook material assemblies 206 are respectively arranged at both ends of the third guide plate 205.

[0059] The first follower assembly is used to drive the second guide plate 204 to extend or retract following the first guide plate 203, with the displacement of the second guide plate 204 being greater than that of the first guide plate 203. The second follower assembly is used to drive the third guide plate 205 to extend or retract following the second guide plate 204, with the displacement of the third guide plate 205 being greater than that of the second guide plate 204. The telescopic drive mechanism 202 is used to synchronously drive the two first guide plates 203 to extend out of the first opening 2011 or the second opening 2012, or to synchronously drive the two first guide plates 203 to retract onto the carrier 201. When the first guide plate 203 extends or retracts, the second guide plate 204 and the third guide plate 205 move in the same direction as the first guide plate 203.

[0060] The design of the first guide plate 203, the second guide plate 204, and the third guide plate 205 allows the fork mechanism to have a long reach, allowing it to reach deep into the interior of the shelf. Furthermore, the fork mechanism 200 can be extended from either the first opening 2011 or the second opening 2012, respectively, enhancing its applicability and practicality. Furthermore, the use of a first follower assembly to extend or retract the second guide plate 204 in conjunction with the first guide plate 203, and a second follower assembly to extend or retract the third guide plate 205 in conjunction with the second guide plate 204, resolves transmission issues during long-travel movements of the fork mechanism and ensures stability during cargo movement.

[0061] In one embodiment, the first follower assembly includes a first guide member 207, a first connector 208, a second guide member 209, and a second connector 210. The first guide member 207 and the second guide member 209 are both pulley structures, and the first connector 208 and the second connector 210 are both flexible belt structures. The first guide member 207 is mounted on the first guide plate 203 near the first opening 2011. One end of the first connector 208 is connected to the support plate 2013, and the other end passes through the first guide member 207 and then connects to the second guide plate 204. The connection points between the first connector 208, the support frame 201, and the second guide plate 204 are both near the second opening 2012. The second guide member 209 is mounted on the first guide plate 203 near the second opening 2012. One end of the second connector 210 is connected to the support plate 2013, and the other end passes through the second guide 209 and then connects to the second guide plate 204. The connection points between the second connector 210, the support frame 201, and the second guide plate 204 are both near the first opening 2011.

[0062] Furthermore, the second follower assembly includes a third guide member 211, a third connector 212, a fourth guide member 213, and a fourth connector 214. The third guide member 211 and the fourth guide member 213 are both pulley structures, while the third connector 212 and the fourth connector 214 are both flexible belt structures. The third guide member 211 is mounted on the second guide plate 204 and is adjacent to the first opening 2011. One end of the third connector 212 is connected to the first guide plate 203 and is adjacent to the second guide member 209. The other end passes around the third guide 211 and is connected to the third guide plate 205. The connections between the third connector 212 and the first guide plate 203 and the third guide plate 205 are both adjacent to the second opening 2012. The fourth guide member 213 is installed on the second guide plate 204 and is close to the second opening 2012. One end of the fourth connecting member 214 is connected to the first guide plate 203 and is close to the first guide member 207. The other end bypasses the fourth guide member 213 and is connected to the third guide plate 205. The connection points between the fourth connecting member 214 and the first guide plate 203 and the third guide plate 205 are all close to the first opening 2011.

[0063] See Figure 10-20 ,exist Figure 19 In the figure, the connection between the first connecting member 208 and the support plate 2013 is marked as connection 1, and the connection between the first connecting member 208 and the second guide plate 204 is marked as connection 2. The connection between the second connecting member 210 and the support plate 2013 is marked as connection 3, and the connection between the second connecting member 210 and the second guide plate 204 is marked as connection 4. When the first guide plate 203 moves toward the first opening 2011 or the second opening 2012, the positions of connection 1 and connection 3 do not change.

[0064] exist Figure 20 , the connection between the third connector 212 and the second guide plate 204 is marked as connection 5, and the connection between the third connector 212 and the third guide plate 205 is marked as connection 6. The connection between the fourth connector 214 and the second guide plate 204 is marked as connection 7, and the connection between the fourth connector 214 and the third guide plate 205 is marked as connection 8.

[0065] Taking the telescopic drive mechanism 202 driving two fork arm mechanisms as an example, the first follower assembly and the second follower assembly are described:

[0066] When the telescopic drive mechanism 202 drives the two first guide plates 203 to extend from the first opening 2011, the first guide member 207 is mounted on the first guide plates 203 near the first opening 2011. One end of the first connecting member 208 is fixed to the connection 1, while the other end of the first connecting member 208 is connected to the second guide plate 204 via the connection 2. Therefore, as the first guide plates 203 move, the first connecting member 208 pulls the second guide plates 204, along with the first guide plates 203, out of the first opening 2011. Simultaneously, the displacement of the second guide plates 204 is greater than that of the first guide plates 203, meaning that the ends of the second guide plates 204 extend further than the ends of the first guide plates 203. Furthermore, the second guide plates 204 move faster than the first guide plates 203.

[0067] Since one end of the third connecting member 212 is connected to the first guide plate 203 through the connection 5, and the other end is connected to the third guide plate 205 through the connection 6, and the movement speed of the second guide plate 204 is faster than the movement speed of the first guide plate 203, therefore, when the first guide plate 203 and the second guide plate 204 move, the movement speed of the third guide member 211 is faster than the movement speed of the connection 5. At this time, one end of the third connecting member 212 is equivalent to being dragged by the connection 5, then the third connecting member 212 will pull the third guide plate 205 out of the first opening 2011 through the connection 6, and the displacement of the third guide plate 205 is greater than the displacement of the second guide plate 204, that is, the end of the third guide plate 205 extends farther than the end of the second guide plate 204, and the speed of movement of the third guide plate 205 is also faster than that of the second guide plate 204. In this way, the hook assembly 206 installed at the end of the third guide plate 205 can be moved to the rear side of the material stored on the shelf, thereby facilitating the subsequent pushing of the material onto the carrier 201.

[0068] When the telescopic drive mechanism 202 drives the two first guide plates 203 to retract, the second guide member 209 is mounted on the first guide plate 203 near the second opening 2012, one end of the second connecting member 210 is fixed to the connection 3, and the other end of the second connecting member 210 is connected to the second guide plate 204 via the connection 4. Therefore, when the first guide plate 203 moves, the second connecting member 210 pulls the second guide plate 204 through the connection 4 to retract along with the first guide plate 203 onto the carrier 201, and the second guide plate 204 retracts faster than the first guide plate 203.

[0069] Since one end of the fourth connecting member 214 is connected to the first guide plate 203 via the connection 7 and the other end is connected to the third guide plate 205 via the connection 8, and the second guide plate 204 moves faster than the first guide plate 203, while the first and second guide plates 203 and 204 are moving, the fourth guide member 213 moves faster than the connection 7. At this time, one end of the fourth connecting member 214 is effectively being dragged by the connection 7, and the fourth connecting member 214 pulls the third guide plate 205 back via the connection 8. Furthermore, the third guide plate 205 moves faster than the second guide plate 204. In this way, the material hook assembly 206 can move and push materials from the shelf onto the carrier 201.

[0070] The structural design of the first follower assembly and the second follower assembly fully utilizes the space between the support plate 2013, the first guide plate 203, the second guide plate 204 and the third guide plate 205, making the fork arm mechanism thinner and the overall structure more compact.

[0071] The structural design of the first and second follower assemblies fully utilizes the space between the support plate 2013, the first guide plate 203, the second guide plate 204, and the third guide plate 205. This not only increases the extension length of the fork arm mechanism, but also makes the fork arm mechanism thinner, occupies less space, and has a more compact overall structure, thereby improving the space utilization of the fork mechanism. In this embodiment, the lengths of the first guide plate 203, the second guide plate 204, and the third guide plate 205 are all 720 mm, and the maximum extension length of the fork arm mechanism reaches 1500 mm. This structural design enables the fork arm mechanism to achieve a longer extension length without excessively increasing the lengths of the first guide plate 203, the second guide plate 204, and the third guide plate 205, streamlining the overall structure and making it suitable for widespread use.

[0072] In one embodiment, to make the overall structure more compact, the first guide member 207 and the second guide member 209, as well as the first connector 208 and the second connector 210, are staggered in height. The third guide member 211 and the fourth guide member 213, as well as the third connector 212 and the fourth connector 214, are staggered in height. The first guide member 207 and the fourth guide member 213, as well as the first connector 208 and the fourth connector 214, are located at the same height. The second guide member 209 and the third guide member 211, as well as the second connector 210 and the third connector 212, are located at the same height.

[0073] The first connecting member 208, the second connecting member 210, the third connecting member 212 and the fourth connecting member 214 are all made of belts, wherein the third connecting member 212 and the fourth connecting member 214 are designed with cables, and the cables are externally connected to the power supply system. In this way, the hook component 206 can provide power without the need to use a drag chain for conduction, which saves the use of materials and saves manufacturing costs.

[0074] In one embodiment, the support plate 2013 and the first guide plate 203 are slidably engaged via a second sliding assembly 215, the second guide plate 204 and the first guide plate 203 are slidably engaged via a third sliding assembly 216, and the third guide plate 205 and the second guide plate 204 are slidably engaged via a fourth sliding assembly 217. The second sliding assembly 215, the third sliding assembly 216, and the fourth sliding assembly 217 all employ linear guide rail structures.

[0075] In one embodiment, the telescopic drive mechanism 202 includes a rotating shaft 2021, a second driving member 2022, and two transmission assemblies. The rotating shaft 2021 is rotatably mounted at the bottom of the carrier 201. The second driving member 2022 is mounted on the carrier 201 and is in transmission connection with the rotating shaft 2021. The two transmission assemblies are respectively disposed on either side of the carrier 201. The transmission assemblies include a driving pulley 2023, a driven pulley 2024, a synchronous belt 2025, and a connecting portion. The driving pulley 2023 is disposed at one end of the rotating shaft 2021, the driven pulley 2024 is rotatably mounted on the carrier 201, and the synchronous belt 2025 is respectively wound around the driving pulley 2023 and the driven pulley 2024. The connecting portion is disposed on the first guide plate 203 and is connected to the synchronous belt 2025. Specifically, the connection portion includes multiple connection blocks 2026. The sidewalls of the connection blocks 2026 facing the synchronous belt 2025 are provided with multiple grooves, and the outer sidewalls of the synchronous belt 2025 are provided with protrusions that mate with the grooves. The forward or reverse rotation of the second driving member 2022 drives the drive pulley 2023 to rotate forward or reverse, thereby driving the connection blocks 2026 and the first guide plate 203 toward the first opening 2011 or the second opening 2012 via the synchronous belt 2025.

[0076] In one embodiment, the hook assembly 206 includes a third driving member 2061 and a rocker 2062. The third driving member 2061 is disposed at the bottom of the third guide plate 205, and the rocker 2062 is connected to the third driving member 2061. The hook assembly 206 is prior art and is not described in detail in this embodiment.
