Description

Technical Field

[0001] The present invention relates to the technical field of AGV vehicles, and in particular to an AGV vehicle for sorting cartons. Background Art

[0002] AGV (Automated Guided Vehicles), also known as unmanned guided vehicles, automatic guided vehicles or laser guided vehicles, are known for their unmanned characteristics. These vehicles are equipped with advanced automatic guidance systems and can automatically travel along a preset path without human guidance, accurately transporting goods or materials from the starting point to the destination. The driving path of AGV is highly flexible and can be adjusted according to changes in warehouse layout or production process, and the cost of path change is much lower than traditional conveyor belts and rigid conveyor lines. AGV is usually equipped with a loading and unloading mechanism that can seamlessly connect with other logistics equipment to achieve a fully automated process for loading, unloading and handling of goods.

[0003] However, AGVs need to use fixed transport channels during transportation, and the width of these channels can usually only accommodate cartons of a specific size. If the carton is too large, it cannot pass through the channel; if it is too small, it is easy to fall from the channel. Therefore, traditional AGVs can only handle cartons of a single size and cannot meet the transportation needs of cartons of various sizes.

[0004] To solve this problem, technicians usually design movable clamps on both sides of the AGV's transport channel to accommodate cartons of different sizes. However, in order for the clamps to block the moving route of the cartons, they will occupy a lot of space on the top of the AGV, which will limit the number of cartons the AGV can carry, thus reducing the AGV's transport efficiency and affecting the progress of the carton sorting work. Summary of the invention

[0005] The object of the present invention is to provide an AGV vehicle for carton sorting to solve at least one technical problem existing in the above-mentioned prior art.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figures 1 to 9 The present invention provides a technical solution: an AGV vehicle for carton sorting, comprising:

[0032] The mobile assembly 1 includes an AGV body 11, a circular groove 12 disposed on the top of the AGV body 11, a connecting hole 13 opened on one side of the AGV body 11, a first shaft hole 14 opened on one side of the AGV body 11, a power wheel 15 disposed on the bottom of the AGV body 11, and a rotating member 17 disposed on the outer wall of the power wheel 15;

[0033] In the above, the AGV body 11 is also equipped with electronic components and devices necessary for the AGV vehicle. At the same time, the technicians can also install other devices with different functions on the AGV body 11 as needed;

[0034] It should be noted that a motor connected to the power wheel 15 is also installed in the AGV body 11. The AGV car drives the power wheel 15 to rotate through the motor, so that the AGV car can move in other directions. In order to keep the body balanced when moving, symmetrical auxiliary wheels 16 are installed on both sides of the AGV body 11. The auxiliary wheels 16 are universal wheels. When the AGV car needs to turn, the two power wheels 15 will rotate in opposite directions. At this time, the auxiliary wheels 16 can autonomously make changes in the bottom and rotate in the direction of rotation of the power wheel 15, so that the AGV body 11 can also maintain balance when turning;

[0035] It should also be noted that the power wheel 15 is connected to the rotating part 17 by bolts. When the power wheel 15 rotates, the rotating part 17 will also be driven to rotate. At this time, the balance of the AGV body 11 is broken. Therefore, in order to ensure the balance of the AGV body 11 when walking, it is necessary to perform a dynamic balancing test on the AGV body 11 and then install a corresponding configuration on the other side of the AGV body 11 to maintain the balance of the AGV body 11 when walking.

[0036] The storage component 2 is arranged on the AGV body 11, and includes a placement member 21 and a trigger member 22 connected to one side of the placement member 21. The placement member 21 includes a rotating block 211 rotatably connected to the outer wall of the circular groove 12, a material trough 212 arranged on the outer wall of the rotating block 211, a limiting hole 213 arranged on one side of the rotating block 211, a second shaft hole 214 opened at the top of the rotating block 211, and a roller shaft 215 arranged on one side of the material trough 212. The placement member 21 includes a connection cover 221 in contact with the top of the rotating block 211, a rotating disk 222 connected to the bottom of the connection cover 221, a rotating shaft 223 arranged at the bottom of the rotating disk 222, a cam 224 connected to the bottom of the rotating shaft 223, and a handle 226 arranged on the outer wall of the connection cover 221;

[0037] In the above, the cross-sectional shape of the circular groove 12 is semicircular, and its diameter is the same as the diameter of the rotating block 211, and it fits the outer surface of the rotating block 211. Here, the rotating block 211 can rotate in the circular groove 12;

[0038] It should be noted that the connection cover 221 is semicircular in shape, and can be combined with the rotating block 211 to form a nearly circular cylinder. The rotating block 211 can be rotated by holding the handle 226, thereby driving the rotating disk 222, the rotating shaft 223, and the cam 224 to rotate, so that the storage assembly 2 achieves the desired effect;

[0039] It should also be noted that there is enough space in the rotating block 211 to place the cam 224, and the cam 224 can rotate in the rotating block 211;

[0040] It should be noted that three troughs 212 of different sizes are provided on the rotating block 211, so that when placing cartons into the AGV, the operator can place different cartons into troughs 212 of different widths according to the size of the cartons. In this way, the AGV can carry cartons of different sizes to move during the movement, thereby increasing the capacity of the AGV and improving the transportation efficiency of the AGV.

[0041] It should also be noted that a roller 215 is provided at the bottom of each material trough 212, which can reduce the friction when the carton moves to increase the unloading speed of the carton. At the same time, if you want to increase the unloading speed of the AGV vehicle, you can also install a roller in the groove on the top of the AGV body 11, so that the carton can also reduce the friction through the roller when moving onto the AGV body 11.

[0042] The outer wall of the rotating shaft 223 is rotatably connected to the inner wall of the second shaft hole 214, and the outer wall of the cam 224 is rotatably connected to the inner wall of the rotating block 211. A bearing can be installed in the second shaft hole 214, and then the rotating shaft 223 is installed through the bearing. In this way, the friction force when the rotating shaft 223 rotates can be reduced, the loss of the rotating shaft 223 is reduced, and the rotation speed of the rotating shaft 223 is also increased.

[0043] The inner wall of the limiting hole 213 is provided with a linkage assembly 3, which includes a rotating rod 31 rotatably connected to the outer wall of the limiting hole 213, a special-shaped wheel 32 connected to one side of the rotating rod 31, a long strip block 35 connected to the outer wall of the rotating rod 31, and a mounting plate 38 connected to one side of the rotating rod 31. The outer walls on both sides of the rotating rod 31 are rotatably connected to the connecting hole 13 and the outer wall of the first shaft hole 14 respectively, the outer wall of the mounting plate 38 is rotatably connected to the inner wall of the connecting hole 13, a fixing block 18 is installed on one side of the connecting hole 13 facing the mounting plate 38, and a fixing block 2 39 is provided on one side of the mounting plate 38 facing the fixing block 18;

[0044] In the above, in order to drive the rotating block 211 to rotate through the rotating rod 31, a long block 35 is set on the rotating rod 31, and when the rotating block 211 rotates, each trough 212 will move to the top one by one in sequence, and the bottom of each trough 212 is flush with the bottom of the groove at the top of the rotating block 211, so when a trough 212 rotates to the top, the carton stored therein can be taken out, which can improve the transportation efficiency of the carton, and at the same time, the movement route of the carton can be restricted by the two sides of the trough 212 to prevent the carton from deviating from the movement trajectory;

[0045] It should be noted that no long strips 35 are provided on both sides of the rotating rod 31 , and the long strips 35 are provided only on the outer wall of the rotating rod 31 connected to the limiting hole 213 .

[0046] The rotating member 17 includes a rotating wheel 171 whose outer wall is connected to the power wheel, a first conical tooth 172 arranged on one side of the rotating wheel 171, and a connecting sleeve 173 connected to the outer wall of the rotating wheel 171. The rotating wheel 171 is a cylindrical body as a whole, and a plurality of first conical teeth 172 are arranged on one side of the rotating wheel 171. The first conical teeth 172 are only half the width of the rotating wheel 171.

[0047] It should be noted that the connecting sleeve 173 is used to connect the rotating rod 31. It is sleeved on the rotating rod 31, and the two need to be fixed together by bolts.

[0048] The outer wall of the special-shaped wheel 32 is provided with an arc groove 33 which is rotatably connected to the outer wall of the rotating wheel 171. A second conical tooth 34 is provided on one side of the special-shaped wheel 32. The diameter of the arc groove 33 is the same as the diameter of the rotating wheel 171. Therefore, when the arc groove 33 contacts the rotating wheel 171, the rotation of the rotating wheel 171 will not drive the special-shaped wheel 32 to rotate. When the first conical tooth 172 rotates to the arc groove 33, the first conical tooth 172 will push one side of the arc groove 33, thereby causing the special-shaped wheel 32 to rotate, and then the second conical tooth 34 on the special-shaped wheel 32 The shaped wheel 32 can be quickly driven to rotate, and the shaped wheel 32 can then drive the rotating rod 31 to rotate, so that the material trough 212 on the rotating block 211 can be converted. Here, the length of the first conical tooth 172 and the second conical tooth 34 is limited, so when the first conical tooth 172 and the second conical tooth 34 are engaged to the end, the arc groove 33 will rotate and engage with the outer wall of the rotating wheel 171, so that the shaped wheel 32 cannot rotate, so that the shaped wheel 32 can perform intermittent motion.

[0049] The outer wall of the long strip block 35 is slidably connected to the outer wall of the limiting hole 213, and a notch 36 is provided on the top of the long strip block 35 for contacting the outer wall of the cam 224. The outer wall of the rotating rod 31 is sleeved with an elastic member 37 connected to the inner wall of the rotating block 211. When the connecting cover 221 is rotated, the rotating shaft 223 can be driven to rotate, and then the cam 224 can be driven to rotate. When the cam 224 rotates, the raised portion thereon will gradually squeeze the long strip block 35 in contact with the cam 224. At this time, the long strip block 35 and the rotating rod 31 will move, and the rotating rod 31 will squeeze the elastic member 37, and the special-shaped wheel 32 will move away from the direction of the AGV body 11. This will cause the arc groove 33 to move to a place where the rotating wheel 171 is not provided with the first conical teeth 172. In this way, no matter how the rotating wheel 171 is selected, the first conical teeth 172 cannot contact the second conical teeth 34, so that the special-shaped wheel 32 cannot rotate.

[0050] In summary, when it is necessary to remove the carton in the trough 212, it is necessary to ensure that the arc groove 33 of the special-shaped wheel 32 moves to the position where the rotating wheel 171 is provided with the first conical tooth 172. When the motor drives the power wheel 15 to rotate, it can drive the rotating wheel 171 to rotate, thereby driving the special-shaped wheel 32 and the rotating block 211 to perform intermittent motion. In this way, when the AGV vehicle moves a sufficient distance, each trough 212 can be rotated to the top in turn, so that the user can quickly and conveniently remove the carton.

[0051] Embodiment 2 provides a limiting method for the connection cover 221 based on embodiment 1;

[0052] A groove 216 is provided on the top of the rotating block 211 and is rotatably connected to the bottom of the rotating disk 222. A limiting groove 217 is provided on the top of the groove 216. A spring piece 225 is provided at the bottom of the rotating disk 222 and is engaged with the limiting groove 217. Among them, a semicircular protrusion is provided at the bottom of the spring piece 225, and the corresponding limiting groove 217 has the same shape as the protrusion. When the connecting cover 221 rotates, the rotating disk 222 is driven to rotate, which in turn drives the spring piece 225 to rotate. At this time, the spring piece 225 will move to the outer wall of the rotating block 211, and the spring piece 225 will be squeezed. Only when the spring piece 225 rotates to another limiting groove 217, the spring piece 225 will return to its original state, and at this time, the spring piece 225 will push the protrusion into the limiting groove 217, so that when the rotating cover 221 rotates, the resistance of the rotating cover 221 will be increased, so that the rotating cover 221 can be prevented from rotating at will.

[0053] Embodiment 3, based on the above embodiment, some adaptive adjustments are made to meet the above functions:

[0054] Specifically, the mobile component 1 includes an AGV body 11, a circular groove 12 arranged on the top of the AGV body 11, a connecting hole 13 opened on one side of the AGV body 11, a first axial hole 14 opened on one side of the AGV body 11, a power wheel 15 arranged at the bottom of the AGV body 11 and a rotating part 17 arranged on the outer wall of the power wheel 15. Among them, the shape of the top of the AGV body 11 is set to be a triangle. This setting increases the height of the AGV body 11 so that the AGV body 11 has enough capacity to accommodate the rotating block 211. At the same time, in order to facilitate the removal of cartons in the trough 212, a groove is also opened on the top of the AGV body 11, so that when the trough 212 rotates to the highest point, the bottom of the trough 212 can be flush with the AGV body 11 to facilitate the transportation of cartons.

[0055] In summary, the working principle of the AGV vehicle is as follows: after a certain number of cartons are placed in the material trough 212, the AGV vehicle is driven forward, so that the rotating wheel 171 drives the special-shaped wheel 32 to rotate through the first conical tooth 172, thereby driving the rotating rod 31 to rotate, to drive the connecting cover 221 to rotate to the top, then the connecting cover 221 is rotated, so that the connecting cover 221 drives the rotating shaft 223 to rotate, and then drives the cam 224 to rotate, and when the cam 224 rotates, the raised part thereon will gradually squeeze the long strip 35 in contact with the cam 224, and at this time, the long strip 35 and the rotating rod 31 will move, and at this time the rotating rod 31 will squeeze the elastic member 37, and at this time the special-shaped wheel 32 will move away from the AGV. The vehicle body 11 moves in the direction of rotation, which will cause the arc groove 33 to move to the place where the rotating wheel 171 is not provided with the first conical tooth 172. In this way, no matter how the rotating wheel 171 is selected, the first conical tooth 172 cannot contact the second conical tooth 34, so that the special-shaped wheel 32 cannot rotate. At this time, when the AGV vehicle moves, the material trough 212 cannot be converted. When the AGV vehicle is about to arrive at the designated location, the connecting cover 221 is rotated again to drive the cam 224 back to its original position so that the special-shaped wheel 32 returns to its original shape. When the AGV vehicle continues to move, the rotating block 211 will rotate accordingly, so that each material trough 212 will move to the top one by one, and the user can take out the cartons one by one.

[0056] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
