Description

Technical Field

[0001] The present application relates to the field of forklift robot devices, and in particular to a transport AGV device. Background Art

[0002] AGV pallet truck is a kind of forklift robot. The existing AGV pallet truck mainly works by inserting the fork into the bottom hole of the pallet, lifting the goods, and then transporting the pallet and the goods, thereby realizing automatic forking and transporting of the pallet and the goods.

[0003] Existing AGV pallet trucks can generally only carry Sichuan-shaped pallets, iron pallets or goods with fork holes, and are not suitable for carrying Tian-shaped pallets or goods with bottom bars. If you forcibly fork a Tian-shaped pallet truck or goods with a bottom bar, the vehicle's load-bearing wheels will interfere with the bottom edge of the Tian-shaped pallet or the bottom bar of the goods when rolling forward, and you need to rely on the load-bearing wheels to roll over the bottom edge of the Tian-shaped pallet or the bottom bar of the goods. When the load-bearing wheels roll over the bottom edge of the Tian-shaped pallet or the bottom bar of the goods, a large impact force is generated, which will not only cause damage to the pallet, but also greatly reduce the service life of the pallet.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0037] The present application embodiment discloses a transport AGV device. Figure 1-10 A transport AGV device may include a case component 10, a transport driving component 20, a lifting component 30, and a translation component 40. The transport driving component 20 is connected to the case component 10, and the lifting component 30 is connected to the case component 10.

[0038] The case component 10 may include a device housing 11 , which may be provided with a translation region 111 .

[0039] The transport driving component 20 may include a driving wheel 21. The driving wheel 21 is located at the bottom of the device housing 11. Specifically, there may be four driving wheels 21.

[0040] The translation component 40 may include a translation driving source 41 , a translation active component 42 , a translation matching component 43 , a translation rail 44 , and a translation slider 45 .

[0041] The lifting component 30 may include a fork arm 31 , a lifting portion 32 , a lifting main shell 33 , a lifting guide wheel 34 , a width limiting wheel 35 , a lifting guide rail 36 , a lifting slider 37 , a fixed end support seat 38 , and a supporting end support seat 39 .

[0042] The translation driving source 41 is connected to the translation active member 42, and the translation active member 42 is connected to the translation matching member 43. The translation driving source 41 is connected to the lifting main shell 33, and the translation driving source 41 is located at the back of the lifting main shell 33. The translation matching member 43 is connected to the device shell 11, and the translation matching member 43 is located at the top of the device shell 11.

[0043] The translation driving source 41 drives the translation active member 42 to move. The translation active member 42 cooperates with the translation matching member 43, so that the lifting component 30 moves in translation.

[0044] The translation rail 44 is connected to the device housing 11, and the translation rail 44 is located on the side of the device housing 11. The translation slider 45 is connected to the lifting main housing 33, and the translation slider 45 is located on the side of the lifting main housing 33. The translation slider 45 is connected to the translation rail 44. Through the translation slider 45 and the translation rail 44, it is convenient to guide the translation movement direction of the lifting component 30, and the load sharing pressure can also be reduced.

[0045] Specifically, the translation active member 42 may be a gear, and the translation matching member 43 may be a rack.

[0046] Specifically, the fork arm 31 is located in the translation area 111 . The translation movement of the lifting component 30 causes the fork arm 31 to move in the translation area 111 .

[0047] The lifting main shell 33 may be provided with a lifting area 331. The lifting guide wheel 34 and the width limiting wheel 35 are connected to the fork arm 31. The fork arm 31 partially extends into the lifting main shell 33, specifically, the fork arm 31 partially extends into the lifting area 331. The lifting guide wheel 34 is connected to the lifting main shell 33.

[0048] The lifting part 32 drives the fork arm 31 to move up and down, and the lifting guide wheel 34 moves in the lifting area 331. The setting of the lifting guide wheel 34 can facilitate the lifting part 32 to drive the fork arm 31 to move up and down, improve the smoothness of the lifting movement, and can also facilitate the guidance of the direction of the lifting movement. The setting of the width limiting wheel 35 can also further improve the smoothness of the lifting movement, facilitate the guidance of the lifting direction, and can also improve the anti-overturning ability during the lifting process, and improve the stability of the entire lifting device.

[0049] The lifting rail 36 is connected to the lifting slider 37, and the lifting rail 36 is connected to the fork arm 31. The lifting slider 37 is connected to the lifting part 32. The lifting rail 36 and the lifting slider 37 facilitate the movement direction of the lifting part 32, and can also reduce the load of the fork arm 31 and share the pressure.

[0050] The fixed end support seat 38 and the supporting end support seat 39 are connected to the fork arm 31. The fixed end support seat 38 and the supporting end support seat 39 are convenient for fixing the lifting part 32.

[0051] The lifting part 32 may include a lifting driving source 321 , a lifting active part 322 , a lifting driven part 323 , a lifting transmission part 324 , a lifting actuator 325 , a lifting limiter 326 , a nut seat 327 , a coupling 328 , and a support part 329 .

[0052] The lifting driving source 321 is connected to the lifting active member 322 through the coupling 328, and the lifting active member 322 is connected to the lifting driven member 323. The lifting driven member 323 is connected to the nut seat 327, and the nut seat 327 is connected to the lifting transmission member 324. The lifting actuator 325 is rotatably connected to the lifting transmission member 324, and the lifting limit member 326 is rotatably connected to the lifting actuator 325. The lifting limit member 326 is connected to the fork arm 31. The support member 329 is connected to the lifting actuator 325. The lifting active member 322 is arranged through the fixed end support seat 38 and the supporting end support seat 39.

[0053] The lifting driving source 321 drives the lifting active member 322 to move, thereby driving the lifting follower 323 to move. The lifting follower 323 moves linearly. The movement of the lifting follower 323 drives the nut seat 327 to move, and the movement of the nut seat 327 drives the lifting transmission member 324 to move. The movement of the lifting transmission member 324 drives the lifting actuator 325 to move, and under the restriction of the lifting limit member 326, the lifting actuator 325 moves toward the ground 300.

[0054] As the lifting drive source 321 continues to drive, the support member 329 on the lifting actuator 325 contacts the ground 300. The lifting drive source 321 is still driving, and under the restriction of the ground 300, the lifting limit member 326 pushes the fork arm 31 to move up and down.

[0055] The fork arm 31 may include a lifting member 311 and a fork arm body 312, wherein the lifting member 311 is connected to the fork arm body 312. The lifting limiter 326 is connected to the lifting member 311. The lifting member 311 can facilitate the lifting limiter 326 to transmit force, so that the lifting limiter 326 can lift the fork arm 31.

[0056] Specifically, the lifting member 36 is fixedly connected to the fork arm body 312 , and the lifting limit member 326 is rotatably connected to the lifting member 36 .

[0057] Specifically, the lifting active member 322 may be a screw, the lifting driven member 323 may be a nut, and the lifting active member 322 and the lifting driven member 323 may be driven by the screw. Alternatively, the lifting active member 322 may be a screw, the lifting driven member 323 may be a nut, and the lifting active member 322 and the lifting driven member 323 may be driven by the screw.

[0058] Specifically, the number of lifting transmission members 324 in the lifting part 32 can be 2, and the lifting transmission members 324 are located on both sides of the lifting follower 323. The number of lifting actuators 325 can be 4, and the number of lifting limit members 326 can be 4. The number of translation rails 44 can be 2, and the number of translation sliders 45 can be 2.

[0059] It can be understood that the working process of the transport AGV device of the present application is:

[0060] The driving wheel 21 drives the transport AGV device to move to the specified position;

[0061] The translation component 40 drives the lifting component 30 to perform translational movement; the fork arm 31 moves in the translation area 111 and then penetrates the tray 200; at this time, the support member 329 is away from the ground 300;

[0062] After the fork arm 31 reaches the specified distance, the translation component 40 stops driving and the fork arm 31 stops moving;

[0063] The lifting driving source 321 drives the lifting actuator 325 to move toward the ground 300, and the supporting member 329 contacts the ground 300;

[0064] The lifting driving source 321 continues to drive, and the lifting actuator 325 pushes the fork arm 31 to move upward; the upward movement of the fork arm 31 drives the pallet 200 to rise; the pallet 200 leaves the ground 300;

[0065] After the fork arm 31 is lifted to a specified distance, the lifting drive source 321 stops driving;

[0066] The driving wheel 21 drives the transport AGV device to move and transport the pallet 200 to the next designated location;

[0067] The lifting driving source 321 drives the lifting actuator 325 to move, and the lifting actuator 325 drags the fork arm 31 to move downward;

[0068] The fork arm 31 is lowered to a specified distance; the pallet 200 contacts the ground 300;

[0069] The lifting driving source 321 drives the lifting actuator 325 to move, and the lifting actuator 325 moves away from the ground 300 until the lifting actuator 325 reaches a specified distance away from the ground 300;

[0070] The translation component 40 drives the lifting component 30 to perform a translation motion; the fork arm 31 moves in the translation area 111, and then the fork arm 31 disengages from the pallet 200;

[0071] The translation component 40 drives the lifting component 30 to move a specified distance; the driving handling AGV device is driven to disengage from the contact with the pallet 200, and the driving wheel 21 drives the handling AGV device to move to the next specified position.

[0072] It can be understood that through the design of the handling AGV device in this application, the lifting of the support member 329 can prevent the support member 329 from interfering with the bottom edge of the cross-shaped pallet 200 or the bottom bar of the goods when the forklift forks the cross-shaped pallet 200 or the pallet 200 with a bottom bar, and there is no longer a need to rely on the support member 329 to roll over the bottom edge of the cross-shaped pallet 200 or the bottom bar of the goods. This can prevent the impact force generated by the support member 329 rolling over the bottom edge of the cross-shaped pallet 200 or the bottom bar of the goods from damaging the pallet 200 and reducing the service life of the pallet 200; it can also prevent the support member 329 from cracking and being damaged after being subjected to a large impact force, affecting the normal use of the vehicle; moreover, it can prevent the vehicle attitude from shifting due to a large impact force, causing uncontrollable changes in the vehicle positioning and navigation, thereby affecting the entire forklift's forking of the pallet 200 or goods.

[0073] The integrated design of the lifting of the fork arm 31 on the forklift and the lifting of the support member 329 enables the lifting device to have both the functions of lifting the fork arm 31 and lifting the support member 329, which can simplify the forklift structure, reduce the forklift cost, and reduce the volume of the forklift. There is no need for an extra lifting device to achieve the lifting of the support member 329.

[0074] The translational design of the fork arm 31 can improve the flexibility of the handling AGV device, automatically adjust the length according to the size of the pallet 200, adapt to the sizes of different pallets 200, shelves or goods, improve the versatility of the handling scenario, be suitable for multi-specification warehousing environments, and reduce the dependence on fixed-size shelves. It can also reduce the volume of the forklift, facilitate movement and turning in narrow aisles or high-density warehousing environments, and reduce the collision risk.

[0075] It can be understood that through the design of the layout of the 4 driving wheels 21 in this application, omnidirectional movement can be achieved, such as straight-line movement, translation, diagonal movement, in-situ rotation, etc., which is particularly suitable for narrow spaces or complex path scenarios. It can also improve the load-bearing capacity and stability, and improve the control accuracy and obstacle avoidance ability.

[0076] It can be understood that this application does not specifically limit the specific quantity of the lifting transmission member 324, the specific quantity of the lifting actuator 325, and the specific quantity of the lifting limit member 326. It does not affect the technical solution of this application to achieve its functions and reach its technical effects.

[0077] It is understandable that the lifting transmission member 324 is a preferred embodiment of the embodiment of the present application. The lifting transmission member 324 may not be included. The lifting actuator 325 may be connected to the lifting follower 323 or the nut seat 327. It does not affect the technical solution of the present application to achieve its function and achieve its technical effect.

[0078] It is understandable that the nut seat 327 is a preferred embodiment of the present application. The nut seat 327 may be omitted without affecting the function and technical effect of the present application's technical solution.

[0079] It is understandable that the present application does not impose any specific restrictions on the specific number of the lifting followers 323. The specific number of the lifting followers 323 does not affect the technical solution of the present application in achieving its functions and technical effects.

[0080] For example, there may be multiple lifting followers 323 , and the lifting followers 323 are connected to the lifting actuator 325 . The lifting active member 322 drives the multiple lifting followers 323 to move simultaneously, thereby driving the lifting motion.

[0081] Alternatively, there may be multiple lifting followers 323 connected to the lifting transmission member 324, and the lifting active member 322 drives the multiple lifting followers 323 to move simultaneously, thereby driving the lifting transmission member 324 to move, thereby driving the lifting motion.

[0082] Alternatively, grooves are provided at the positions where the multiple lifting followers 323 are connected to the lifting transmission member 324 to ensure that the movement of the lifting followers 323 has a certain redundancy, thereby avoiding excessively high requirements on the consistency of the moving distances of the multiple lifting followers 323 driven by the lifting active member 322 at the same time.

[0083] It is understandable that the present application does not impose any specific restrictions on the transmission mode of the lifting active member 322 and the lifting driven member 323, which can be one or more of screw drive, lead screw drive, linear motor drive, hydraulic drive, pneumatic drive, gear rack drive, belt drive, and chain drive. It does not affect the technical solution of the present application to achieve its function and achieve its technical effect.

[0084] It can be understood that the present application does not impose any specific restrictions on the transmission method of the translation active component 42 and the translation matching component 43, which can be one or more of screw transmission, lead screw transmission, linear motor transmission, hydraulic transmission, pneumatic transmission, rack and pinion transmission, belt transmission, and chain transmission.

[0085] It is understandable that the lifting main housing 33 is a preferred embodiment of the present application, and the lifting main housing 33 may be omitted without affecting the technical solution of the present application to achieve its functions and technical effects. The translation drive source 41 may be connected to the fork arm 31 .

[0086] It is understandable that the present application does not limit the specific form of the support member 329. The support member 329 can be a wheel, a bearing, or a foot pad, and the present application does not impose any restrictions on this, as long as the support member 329 can be used for ground support.

[0087] It is understandable that the present application does not limit the specific number of driving wheels 21. The number of driving wheels can be 4 or 2. This does not affect the technical solution of the present application in achieving its function and technical effect.

[0088] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
