[0025] Optionally, the above-mentioned cantilever shaft structure includes a cantilever shaft body and a plurality of rollers mounted 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 comprises: a base frame, a loading and unloading structure and a blocking structure, wherein a cantilever shaft structure for supporting materials is arranged on the base frame; the loading and unloading structure comprises 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] When the material in this structure 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 the above-mentioned blocking structure, the degree of automation and safety in the material transfer process are improved, ensuring safe and reliable production.

[0029] 2. The present invention provides an AGV loading and unloading device. When it is necessary to load materials onto the cantilever shaft structure, the rotating mechanism in the loading power assembly drives the loading baffle to rotate upward clockwise, and the telescopic rod drives the rotating mechanism and the loading baffle to move along the second direction toward the material until it reaches the side of the material away from the fixed frame, and the rotating mechanism drives the loading baffle to rotate downward counterclockwise, and the end of the loading baffle away from the rotating mechanism is laid on the side of the product tooling core shaft of the material away from the fixed frame, and the telescopic rod drives the rotating mechanism and the loading baffle to move along the first direction toward the fixed frame, and the product tooling core shaft will touch the blocking structure, and the product tooling core shaft will squeeze the block, so that the block rotates clockwise along the second rotating axis until the block and the cantilever shaft structure are close and compressed, and the product tooling core shaft can sleeve the blocking structure in its hollow core to continue to move along the first direction until the product tooling core shaft is sleeved on the cantilever shaft structure, and the entire material is placed on the cantilever shaft structure along the outer surface of the cantilever shaft structure along the first direction. When the product tooling mandrel is away from the stopper, the stopper becomes a freely hanging state again under the action of the second elastic member and the weight of the stopper itself. The above process can be repeated to realize the feeding 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 block arm is always pressed downward to prevent the block 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, and the unloading baffle fits on the side of the product tooling mandrel close to the fixed frame. The product tooling mandrel 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 mandrel, the product tooling mandrel 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 blocking lever arm, overcoming the elastic force of the first elastic member, driving the blocking lever arm to rotate counterclockwise along the first rotating axis, and the top end of the blocking lever arm abuts against the groove at the end of the cantilever shaft structure. The product tooling mandrel can continue to move in 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 blocking lever arm to reset to the blocking state.

[0032] The entire loading and unloading process is controlled by an external controller, providing an AGV loading and unloading device 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 has a tendency to slide down, if the material baffle is directly driven to rotate, it is easy to cause the material baffle to touch the product on the product tooling mandrel. By setting the above-mentioned blocking structure, the falling tendency of the material will be automatically blocked by the blocking structure, so as to avoid the material baffle from touching the product on the product tooling mandrel during the rotation and movement of the material baffle, thereby avoiding damage to the product. Moreover, the entire blocking structure is reasonable, purely mechanical, compact, does not require power, and has good economic benefits. When 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, and safe and reliable production is ensured. 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 both sides, the side frames on both sides extend along the first direction, the two side frames are arranged in parallel, the two ends of the fixed frame are respectively fixed to the two side frames, and in order to ensure the subsequent expandable extension, it is necessary to ensure that the fixed frame and the two side frames are arranged vertically. The two side frames and the middle 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 installed at the center of the fixing frame, and the cantilever shaft structure 2 is horizontally arranged 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 on 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, which is embedded in the inside of another side frame. A slider is installed at the output end of the motor screw mechanism. The slider is installed on the screw and protrudes. One end of the unloading baffle 322 is fixed on the slider, and the other end extends horizontally to the loading and unloading 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 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, and a groove is provided 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 is provided with a first mounting groove facing the direction of the material, and the first mounting groove is also open toward the direction of the material and downward. A through hole is horizontally provided 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 provided with through holes 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 axis 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 lever 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 lever arm 42 from continuing to rotate clockwise. However, due to the arc-shaped corner arrangement of the blocking lever arm 42 close to the first rotation axis, the blocking lever 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 for the blocking arm 42, so that the first plane of the blocking arm 42 always fits the first rotation limit surface 47 when there is no external force.

[0062] The blocking assembly is installed at the end of the blocking lever arm 42 away from the mounting frame 41. A second mounting groove is provided at the end of the blocking block 44 close to the blocking lever arm 42, and a through hole is provided at the upper and lower parts of the blocking block 44. The end of the blocking lever arm 42 away from the mounting frame 41 is installed in the second mounting groove by passing the second rotating axis through the through hole above the blocking block 44 and the through hole at the end of the blocking lever arm 42 away from the mounting frame 41, and the blocking block 44 is hinged to the blocking lever 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 lever arm 42 away from the mounting frame 41 corresponding to the second rotation limiting surface 48. When the blocking block 44 rotates along the fourth counterclockwise direction, the second rotation limiting surface 48 is contacted with the second plane, preventing the blocking block 44 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 lever arm 42 away from the mounting frame 41 is also set to be arc-shaped, so that it can continue to rotate along the third clockwise direction, and the inner side wall of the end of the blocking lever arm 42 away from the mounting frame 41 until it is in contact with the other end face of the second groove.

[0063] The third rotating shaft is fixed through the hole below the stopper 44, and the blocking member 45 is arranged on both sides of the third rotating shaft. A first fixing rod is also arranged on both sides of the blocking lever arm 42, and a second fixing rod is fixed on both sides of the blocking lever 44. Through holes are provided on the first fixing rod and the second fixing rod. The second elastic member 46 is a tension spring. The two second elastic members 46 are arranged on both sides of the blocking assembly, one end of which is hung in the through hole on the first fixing rod, and the other end of which is hung in the through hole on the second fixing rod. In the absence of external force, the second elastic member 46 always provides elastic force for the blocking lever 44 and the blocking lever arm 42, so that the blocking structure 4 is 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 around product tooling mandrel 52. Product tooling mandrel 52 is a hollow mandrel. Product tooling mandrel 52 is longer than product 51, and both sides protrude from product 51.

[0065] When it is necessary to load the material onto the cantilever shaft body 21, Figure 1 As shown, the rotating mechanism in the feeding power assembly 311 drives the feeding baffle 312 to rotate upward in a clockwise direction, 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 downward in a counterclockwise direction, 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, so that the stopper 44 rotates clockwise along the second rotation axis until the stopper 44 and the cantilever shaft body 21 are compressed to close. Figure 8 The product tooling mandrel 52 can sleeve the blocking structure 4 in its hollow core to continue moving along the first direction until the product tooling mandrel 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 mandrel 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 gravity of the stopper 44. Figure 5 The free falling state in the machine. Repeating the above process can realize 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, and under the action of the second limiting surface, the block 44 is prevented from having a tendency to move 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 material unloading power assembly 321 in the material unloading power assembly 321 drives the material unloading baffle 322 to move in the second direction away from the fixed frame, and the material 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 material unloading power assembly 321 drives the material 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 stop lever 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 stop lever arm 42 is driven to return to the blocking state.

[0068] The entire loading and unloading process is controlled by an external controller, providing an AGV loading and unloading device 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 down, if the unloading baffle 322 is directly driven to rotate, it is easy to cause the unloading baffle 322 to touch the product 51 on the product tooling mandrel 52. By setting the above-mentioned blocking structure 4, the falling tendency of the material will be automatically blocked by the blocking structure 4, so as to avoid the unloading baffle 322 from touching the product 51 on the product tooling mandrel 52 during the rotation and movement of the unloading baffle 322, thereby avoiding damage to the product 51. Moreover, the entire blocking structure 4 is reasonable, a purely mechanical structure, a compact structure, no power required, and good economic benefits. When docking, the material can be blocked when sliding in a free state, can pass through when pushed by an external force, and can also pass through easily when the material is pulled back. The degree of automation and safety in the material transportation process are improved, and safe and reliable production is guaranteed.

[0070] In this embodiment, the cantilever shaft structure 2 includes a cantilever shaft body 21 and a plurality of 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, thereby 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, thereby preventing the product tooling core shaft 52 from being stuck on the blocking structure 4.

[0072] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
