Description

Technical Field

[0001] The present invention relates to the technical field of AGV transport vehicles, and in particular to an AGV loading and unloading device. Background Art

[0002] An Automated Guided Vehicle (AGV) is a transport vehicle equipped with an automatic guidance device (e.g., electromagnetic or optical) that allows it to travel along a prescribed path. It features safety features and various loading and unloading functions. These vehicles, which are driverless in industrial applications, are powered by rechargeable batteries. Their routes and actions are typically controlled by a computer or by electromagnetic tracks attached to the floor. The AGV follows these signals to move and perform their actions.

[0003] AGVs are used in production automation to automatically connect and transport materials. These devices inevitably require automated docking with factory production lines to automatically load and unload materials, ultimately automating the logistics process. However, during transportation, the loading and unloading mechanisms inevitably come into contact with the materials, potentially damaging them. Summary of the Invention

[0012] a first elastic member, one end of which is connected to the blocking arm, and the other end of which is arranged on the top surface of the inner wall of the first mounting groove;

[0013] A blocking assembly is mounted on an end of the blocking lever arm away from the mounting bracket.

[0014] Optionally, a first rotation limiting surface is provided on the inner wall of the first installation groove, and the first rotation limiting surface can be in contact with the blocking lever arm to prevent the blocking lever arm from rotating toward the third direction.

[0015] Optionally, the blocking component includes:

[0016] A stopper, wherein one end of the stopper close to the stopper arm is provided with a second mounting groove, one end of the stopper arm away from the mounting bracket is mounted in the second mounting groove, and the stopper is hinged to the stopper arm;

[0017] A blocking member is installed at the bottom end of the stopper.

[0018] Optionally, a second rotation limiting surface is provided in the second mounting groove, and the second rotation limiting surface can be in contact with an end of the blocking lever arm away from the mounting bracket to prevent the blocking block from rotating toward the fourth direction.

[0019] Optionally, the blocking structure further includes a second elastic member, one end of the second elastic member is connected to the blocking lever arm, and the other end of the second elastic member is connected to the blocking block.

[0020] Optionally, the blocking member is rotatably connected to the stopper.

[0021] Optionally, the feeding mechanism includes: a feeding power assembly and a feeding baffle, wherein the feeding baffle is mounted at an output end of the feeding power assembly, and the feeding power assembly can drive the feeding baffle to rotate and / or drive the feeding baffle to move along the first direction or the second direction;

[0022] Wherein, the loading baffle is suitable for being set up on the side of the product tooling core shaft of the material to push the material to move.

[0023] Optionally, the above-mentioned unloading mechanism includes: an unloading power assembly and an unloading baffle, wherein the unloading baffle is installed at the output end of the unloading power assembly, and the unloading power assembly can drive the unloading baffle to move along the first direction or the second direction;

[0024] Wherein, the unloading baffle is suitable for being set up on the side of the product tooling core shaft of the material to push the material to move.

[0025] Optionally, the above-mentioned cantilever shaft structure includes a cantilever shaft body and a plurality of rollers installed on the cantilever shaft body.

[0026] The technical solution provided by the present invention has the following advantages:

[0027] 1. An AGV loading and unloading device provided by the present invention includes: a base frame, a loading and unloading structure and a blocking structure, wherein a cantilever shaft structure for supporting materials is provided on the base frame; the loading and unloading structure includes a loading mechanism and a unloading mechanism, and the loading mechanism and the unloading mechanism are respectively arranged on the base frame on both sides of the cantilever shaft structure; the loading mechanism is used to push the material toward a first direction to push the material to be sleeved on the cantilever shaft structure; the unloading mechanism is used to push the material toward a second direction away from the first direction to move the material out of the cantilever shaft structure; the blocking structure is arranged at the end of the cantilever shaft structure; the blocking structure has a blocking state in which it can freely hang to abut against the product tooling core shaft of the material to block the material on the cantilever shaft structure from moving toward the second direction.

[0028] In this structure, when the material tends to slide, if the unloading baffle is directly driven to rotate, it is easy for the unloading baffle to touch the product on the product tooling core shaft. By setting up the above-mentioned blocking structure, the degree of automation and safety in the material transfer process are improved, ensuring safe and reliable production.

[0029] The material handling device of the present invention is a material handling device, and the material handling device is a material handling device, and the material handling device is a material handling device. When the product tooling core shaft is away from the stopper, the stopper becomes a free-hanging state again under the action of the second elastic member and the stopper's own gravity. Repeating the above process can realize the loading of multiple materials.

[0030] When the material is placed on the cantilever shaft structure, in the absence of external force, even if the material tends to move away from the fixed frame, the product tooling core shaft abuts against the blocking member, and under the action of the second limiting surface, the block is prevented from moving counterclockwise. In the case of the first elastic member, the blocking arm is always pressed downward to prevent the blocking arm from rotating counterclockwise, thereby preventing the material from falling out.

[0031] When the material needs to be removed, the unloading power assembly in the unloading power assembly drives the unloading baffle to move in the second direction away from the fixed frame. The unloading baffle fits on the side of the product tooling core shaft close to the fixed frame. The product tooling core shaft moves along the outer surface of the cantilever shaft structure in the second direction until it touches the blocking member in the blocking structure in the blocking state. As the unloading power assembly drives the unloading baffle to apply external force to the product tooling core shaft, the product tooling core shaft will squeeze the blocking member and the block. Due to the existence of the second limiting surface, the external force will be applied to the baffle arm, overcoming the elastic force of the first elastic member, driving the baffle arm to rotate counterclockwise along the first rotation axis, and the top of the baffle arm abuts against the groove at the end of the cantilever shaft structure. The product tooling core shaft can continue to move along the second direction until it is separated from the cantilever shaft structure to achieve unloading. After unloading is completed, the elastic force of the first elastic member drives the baffle arm to return to the blocking state.

[0032] The entire loading and unloading process is controlled by an external controller, providing AGV loading and unloading devices to meet the automation requirements when the AGV is connected to the equipment. It has a simple structure and is easy to install and maintain.

[0033] When the material tends to slide, directly rotating the unloading baffle could easily cause it to contact the product on the mandrel. The aforementioned blocking structure automatically arrests the material's downward trend, preventing it from contacting the product on the mandrel during rotation and movement, thus preventing damage. The entire blocking structure is rational, purely mechanical, compact, and requires no power, resulting in high economic benefits. During docking, the material can be blocked while sliding freely, pass through when pushed, and easily pass through when pulled back. This improves the automation and safety of the material transfer process, ensuring safe and reliable production. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Example

[0055] This embodiment provides an AGV loading and unloading device, such as Figures 1 to 9 As shown, it includes: a base frame 1, a loading and unloading structure 3 and a blocking structure 4.

[0056] like Figure 1 As shown, the base frame 1 is an I-shaped frame with side frames on either side. The side frames extend in a first direction and are arranged parallel to each other. The fixed frame is fixed to the two side frames at both ends. To ensure subsequent expansion and extension, the fixed frame and the two side frames must be arranged perpendicularly. The two side frames and the central fixed frame form the I-shaped base frame 1. A loading and unloading area is formed between the two side frames.

[0057] A cantilever shaft structure 2 is mounted at the center of the fixing frame. The cantilever shaft structure 2 is arranged horizontally along the first direction and the second direction. The cantilever shaft structure 2 includes a cylindrical cantilever shaft body 21 and a roller 22 fixed to the cantilever shaft body 21 by screws.

[0058] The loading and unloading structure 3 includes a loading mechanism 31 and a unloading mechanism 32; the loading structure includes a loading power assembly 311 and a loading baffle 312, the loading power assembly 311 includes a telescopic rod and a rotating mechanism, the telescopic rod is fixed on one of the side frames, the rotating mechanism is fixed on the output end of the telescopic rod, one end of the loading baffle 312 is fixed on the rotating mechanism, and the other end extends into the loading and unloading area.

[0059] The unloading mechanism 32 includes: an unloading power assembly 321 and an unloading baffle 322. The unloading power assembly 321 is a motor-screw mechanism embedded in the interior of another side frame. A slider is installed at the output end of the motor-screw mechanism. The slider is mounted on the screw and protrudes. One end of the unloading baffle 322 is fixed to the slider, and the other end extends horizontally into the unloading and loading area. In the initial state, the loading baffle 312 in the loading structure is located at the end position of the cantilever shaft body 21 away from the fixed frame, and the unloading baffle 322 in the unloading structure is located at the head end position where the cantilever shaft structure 2 is connected to the fixed frame. The stroke of the loading structure is relatively large, from the material position to the head end position where the cantilever shaft structure 2 is connected to the fixed frame; the stroke of the unloading structure is relatively short, which is the axial length of the cantilever shaft, that is, the distance from the head end to the end end of the cantilever shaft.

[0060] like Figure 4 As shown, the cantilever shaft structure 2 includes a cantilever shaft body 21, which is a cylindrical body. A groove is formed at the bottom of the end away from the fixing frame, and the groove is open toward the material direction and downward. The blocking structure 4 is installed in the groove. The blocking structure 4 includes: a mounting frame 41, a blocking arm 42, a first elastic member 43 and a blocking assembly; the blocking assembly includes a block 44 and a blocking member 45. Figure 5 As shown, the mounting bracket 41 is fixed on the inner wall of the groove, and the mounting bracket 41 has a first mounting groove facing the material direction, and the first mounting groove is also open in the material direction and downward. A through hole is horizontally opened on the mounting bracket 41 along the axis perpendicular to the cantilever shaft body 21, and the end of the blocking arm 42 close to the mounting bracket 41 and the end away from the mounting bracket 41 are also horizontally opened along the axis perpendicular to the cantilever shaft body 21. The blocking arm 42 is installed in the first mounting groove by passing a first rotating shaft through the through hole on the mounting bracket 41 and the through hole on the side of the blocking arm 42 close to the mounting bracket 41, and the blocking arm 42 is hingedly connected to the mounting bracket 41. A vertical first rotation limit surface 47 is provided inside the first mounting groove, and the end of the blocking arm 42 close to the mounting bracket 41 has a first plane, and the corner position close to the first rotating axis is set to an arc. As shown Figure 6As shown, through the above arrangement, when the blocking arm 42 rotates along the first rotation axis to the first plane abutting on the first rotation limit surface 47, the first rotation limit surface 47 prevents the blocking arm 42 from continuing to rotate clockwise. However, due to the arc-shaped corner arrangement of the blocking arm 42 close to the first rotation axis, the blocking arm 42 can rotate counterclockwise. The third direction is Figure 6 The fourth direction is the clockwise rotation direction of Figure 6 Counterclockwise rotation direction.

[0061] One end of the first elastic member 43 is fixed to the top surface of the inner wall of the first mounting groove, and the other end is fixed to the blocking arm 42. The first elastic member 43 always provides a downward force to the blocking arm 42, so that the first plane of the blocking arm 42 is always in contact with the first rotation limit surface 47 when there is no external force.

[0062] The blocking assembly is installed at the end of the blocking arm 42 away from the mounting bracket 41. A second mounting groove is provided at the end of the block 44 close to the blocking arm 42, and a through hole is provided at the upper and lower ends of the block 44. The second rotating shaft passes through the through hole above the block 44 and the through hole at the end of the blocking arm 42 away from the mounting bracket 41, and the end of the blocking arm 42 away from the mounting bracket 41 is installed in the second mounting groove, and the block 44 is hinged to the blocking arm 42. A second rotation limiting surface 48 is provided inside the second mounting groove, and a second plane is provided at the end of the blocking arm 42 away from the mounting bracket 41 corresponding to the second rotation limiting surface 48. When the block 44 rotates along the fourth counterclockwise direction, until the second rotation limiting surface 48 is in contact with the second plane, the block 44 is prevented from continuing to rotate along the fourth counterclockwise direction. Figure 5 and Figure 6 As shown, in the normal blocking state, there is a large gap below the second groove, and the lower part of the end of the blocking arm 42 away from the mounting bracket 41 is also set to be arc-shaped, so that it can continue to rotate along the third direction clockwise, and the blocking arm 42 is away from the inner side wall of one end of the mounting bracket 41 until it is in contact with the other end face of the second groove.

[0063] The third rotation axis is fixed through the hole below the stopper 44, and the blocking members 45 are arranged on both sides of the third rotation axis. A first fixing rod is also provided on both sides of the blocking arm 42, and a second fixing rod is fixed on both sides of the blocking block 44. Both the first and second fixing rods have through holes. A second elastic member 46 is a tension spring, and the two second elastic members 46 are respectively arranged on either side of the blocking assembly, with one end hooked in the through hole of the first fixing rod and the other end hooked in the through hole of the second fixing rod. In the absence of external force, the second elastic member 46 always provides elastic force to the blocking block 44 and the blocking arm 42, keeping the blocking structure 4 in a state where the second rotation limit surface 48 is in contact with the second plane.

[0064] The above-mentioned materials are product 51 and product tooling mandrel 52. Product 51 is wound on product tooling mandrel 52. Product tooling mandrel 52 is a hollow mandrel. Product tooling mandrel 52 is longer than product 51 and protrudes from product 51 on both sides.

[0065] When it is necessary to load the material onto the cantilever shaft body 21, as shown in FIG. Figure 1 As shown, the rotating mechanism in the feeding power assembly 311 drives the feeding baffle 312 to rotate clockwise upward, and the telescopic rod drives the rotating mechanism and the feeding baffle 312 to move along the second direction toward the direction close to the material until it reaches the side of the material away from the fixed frame, and the rotating mechanism drives the feeding baffle 312 to rotate counterclockwise downward, and the end of the feeding baffle 312 away from the rotating mechanism is placed on the side of the product tooling core shaft 52 of the material away from the fixed frame, and the telescopic rod drives the rotating mechanism and the feeding baffle 312 to move along the first direction toward the direction close to the fixed frame, and the product tooling core shaft 52 will touch the blocking structure 4, and the product tooling core shaft 52 squeezes the stopper 44, causing the stopper 44 to rotate clockwise along the second rotation axis until the stopper 44 and the cantilever shaft body 21 are compressed close to each other. Figure 8 In the state of the product tooling core shaft 52, the blocking structure 4 is sleeved in its hollow core to continue to move along the first direction until the product tooling core shaft 52 is sleeved on the cantilever shaft body 21 and the entire material is placed on the cantilever shaft body 21 along the outer surface of the cantilever shaft body 21 along the first direction. When the product tooling core shaft 52 is away from the stopper 44, the stopper 44 becomes the stopper again under the action of the second elastic member 46 and the weight of the stopper 44 itself. Figure 5 The above process can be repeated to achieve the loading of multiple materials.

[0066] When the material is placed on the cantilever shaft body 21, in the absence of external force, even if the material tends to move away from the fixed frame, the product tooling core shaft 52 abuts against the blocking member 45. Under the action of the second limiting surface, the block 44 is prevented from moving counterclockwise. In the case of the first elastic member 43, the block arm 42 is always pressed downward to prevent the block arm 42 from rotating counterclockwise, thereby preventing the material from falling out.

[0067] When materials need to be removed, such as Figure 1As shown, the unloading power assembly 321 in the unloading power assembly 321 drives the unloading baffle 322 to move in the second direction away from the fixed frame, and the unloading baffle 322 is attached to the side of the product tooling core shaft 52 close to the fixed frame. The product tooling core shaft 52 moves along the outer surface of the cantilever shaft body 21 in the second direction until it touches the blocking member 45 in the blocking structure 4 in a blocking state. As the unloading power assembly 321 drives the unloading baffle 322 to apply external force to the product tooling core shaft 52, the product tooling core shaft 52 will squeeze the blocking member 45 and the block 44. Due to the existence of the second limiting surface, the external force will be applied to the blocking lever arm 42, overcoming the elastic force of the first elastic member 43, and driving the blocking lever arm 42 to rotate counterclockwise along the first rotation axis until as shown in FIG. Figure 8 In the state shown, the top end of the blocking arm 42 abuts against the groove at the end of the cantilever shaft body 21, and the product tooling core shaft 52 can continue to move along the second direction until it is separated from the cantilever shaft body 21 to realize unloading. After unloading is completed, under the elastic force of the first elastic member 43, the blocking arm 42 is driven to return to the blocking state.

[0068] The entire loading and unloading process is controlled by an external controller, providing AGV loading and unloading devices to meet the automation requirements when the AGV is connected to the equipment. It has a simple structure and is easy to install and maintain.

[0069] When the material has a tendency to slide, if the unloading baffle 322 is directly driven to rotate, it is easy for the unloading baffle 322 to touch the product 51 on the product tooling core shaft 52. By setting the above-mentioned blocking structure 4, the falling tendency of the material will be automatically blocked by the blocking structure 4, preventing the unloading baffle 322 from touching the product 51 on the product tooling core shaft 52 during the rotation and movement of the unloading baffle 322, thereby preventing the product 51 from being damaged. Moreover, the entire blocking structure 4 is reasonable, a purely mechanical structure, compact, does not require power, and has good economic benefits. During docking, the material can be blocked when sliding in a free state, can pass through when pushed by external force, and can also pass through easily when the material is pulled back. The degree of automation and safety in the material transfer process are improved, ensuring safe and reliable production.

[0070] In this embodiment, the cantilever shaft structure 2 includes a cantilever shaft body 21 and several rollers 22 installed on the cantilever shaft body 21, thereby reducing the contact area between the cantilever shaft structure 2 and the product tooling core shaft 52, ensuring the smoothness of the product tooling core shaft 52 when sliding on the cantilever shaft body 21 and avoiding blockage.

[0071] In this embodiment, the blocking member 45 is set to be cylindrical and is rotatably connected to the third rotating shaft, so that when the product tooling core shaft 52 contacts the blocking member 45, the blocking member 45 will also rotate, preventing the product tooling core shaft 52 from being stuck on the blocking structure 4.

[0072] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
