Description

Technical Field

[0001] The present invention relates to the technical field of book and periodical transfer, and in particular to an AGV vehicle for transfer. Background Art

[0002] An automatic guided vehicle (AGV) is an industrial vehicle that loads goods automatically or manually, drives automatically along a set route or tows a cargo trolley to a designated location, and then loads and unloads goods automatically or manually. In the process of transporting books and periodicals, most of which are placed on shelves, the automatic guided vehicle will move to the bottom of the shelf, then lift the shelf for transfer, thereby realizing automatic transfer of the shelf.

[0003] However, during the lifting process of the book and magazine shelves, if the book and magazine shelves are not arranged neatly or crookedly, and the automatic guided vehicle has not moved to the correct position, the lifting plate of the automatic guided vehicle cannot be aligned with the book and magazine shelves when it is lifted upward, resulting in misalignment between the lifting plate and the book and magazine shelves. Therefore, when the automatic guided vehicle drives the book and magazine shelves, it is easy to shake, which in turn causes the book and magazine shelves to collapse. In addition, the lifting plate only lifts the book and magazine shelves but does not fix the book and magazine shelves, which may also cause the book and magazine shelves to shake and move during the transportation process, and may also cause the book and magazine shelves to tilt and collapse, causing damage to the book and magazine shelves.

[0036] The correction component includes sliding grooves 41 symmetrically opened on both sides of the upper surface of the lifting plate 31, and the two sliding grooves 41 are slidably connected to the correction plates 42. The bottom of the correction plate 42 is fixedly connected to a pushing plate 43, and a right-angle trapezoidal groove is opened on the pushing plate 43, and the right-angle trapezoidal groove is close to the hydraulic cylinder 3.

The shape of the contact plate 45 is adapted to the shape of the groove, and the depth of the groove is adapted to the thickness of the contact plate 45. , which is used to completely embed the contact plate 45 into the groove after the contact plate 45 moves downward, so that the upper surface of the contact plate 45 can be flush with the upper surface of the lifting plate 31, so that the top of the lifting plate 31 is in plane contact with the bottom of the book shelf, ensuring that the book shelf remains stable during transportation. The lower surface of the contact plate 45 is symmetrically fixedly connected with a pushing rod 46, and the upper surface of the groove of the lifting plate 31 is provided with a hole for the pushing rod 46 to slide up and down.

[0037] like Figure 3 As shown, a protective component for protecting the book and periodical shelves is arranged inside the automatic guided vehicle body 1, and the protective component includes two groups of fixed plates 51 fixedly connected to both sides of the automatic guided vehicle body 1, and each group of fixed plates 51 is provided with two. A multi-section electric telescopic rod 52 is fixedly connected to one side of the fixed plate 51 facing the inside of the automatic guided vehicle body 1, and a protective frame 53 is rotatably connected between the telescopic ends of the two multi-section electric telescopic rods 52 on the same side. The protective frame 53 is composed of two vertical bars and a horizontal bar to form a U shape. There are two protective frames 53, and one protective frame 53 is located on the inner side of the other protective frame 53.

[0038] like Figures 3 to 6 As shown, the protection assembly also includes a guide rod 56 symmetrically fixedly connected to the two protection frames 53 near one end of the multi-section electric telescopic rod 52, and four guide rods 56 are provided. The outer surfaces of the guide rods 56 are fixedly connected to gears 57, such as Figure 4 and Figure 5 As shown, the inner surface of the automatic guided vehicle body 1 is provided with a guide groove 54 corresponding to the position of the guide rod 56. Figure 6 As shown, the top of the guide groove 54 wall and one end away from the gear 57 is fixedly connected with convex teeth 55 arranged in a linear array. The number of convex teeth 55 is the same as one-fourth of the number of teeth of the gear 57. After the gear 57 is meshed with the convex teeth 55, the gear 57 can drive the protective frame 53 to rotate ninety degrees through the guide rod 56.

[0039] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a support assembly for supporting anti-dumping is provided at the bottom of the protective frame 53, and the support assembly includes four retraction grooves 61 symmetrically opened at the bottom of the two protective frames 53, and an electric rotating shaft 62 is fixedly installed inside the retraction groove 61 and away from the groove wall of the multi-section electric telescopic rod 52. The electric rotating shaft 62 is externally connected to an inclination detector for controlling the rotation of the electric rotating shaft 62 after the inclination detector detects the inclination, and a first support rod 63 is fixedly installed on the electric rotating shaft 62.

[0040] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the support assembly also includes a movable groove 64 provided in the first support rod 63, and the bottom of the first support rod 63 is provided with positioning holes 65 arranged in a linear array, and the positioning holes 65 are connected to the movable groove 64, and the end of the movable groove 64 close to the electric rotating shaft 62 is fixedly connected to the second spring 66, and the end of the second spring 66 away from the electric rotating shaft 62 is fixedly connected to the second support rod 67, and the second support rod 67 slides inside the movable groove 64, and the end of the second support rod 67 close to the movable groove 64 is provided with a clamping groove 68, and the top of the clamping groove 68 is fixedly connected to the third spring 69, and the bottom end of the third spring 69 is fixedly connected to the clamping block 610, and the clamping block 610 slides inside the clamping groove 68, and the left side of the clamping block 610 is a plane and the right side is an inclined surface, that is, Figure 8 As shown on the left and right, the inclined surface of the block 610 does not affect the movement of the second support rod 67 when the second support rod 67 is pushed by the second spring 66, and the plane of the block 610 is used to engage with the positioning hole 65 to position the second support rod 67 when the second support rod 67 is squeezed by external force.

[0041] The following is the entire working process and working principle of the above embodiment:

[0042] The initial state is:

[0043] The output shaft of the hydraulic cylinder 3 is not extended, the lifting plate 31 is retracted in the inner chamber 11, the contact plate 45 is not squeezed, and the first spring 44 is not compressed by the contact plate 45. The correction plate 42 is at the outermost side of the sliding groove 41 and is not aggregated to the middle. The telescopic axis of the multi-section electric telescopic rod 52 is not extended, the protective frame 53 is at the bottom of the lifting plate 31 and is in a horizontal state. The second support rod 67 is in conflict with the groove wall of the retraction groove 61, and the second support rod 67 makes the second spring 66 in a compressed state. Figure 8 As shown, the block 610 abuts against the slot wall of the movable slot 64 , so that the block 610 compresses the third spring 69 .

[0044] The working status is:

[0045] The automatic guided vehicle body 1 is started, and the automatic guided vehicle body 1 drives the driving wheel 2 to rotate through the built-in driving device. The rotation of the driving wheel 2 drives the automatic guided vehicle body 1 to move on the ground. At the same time, the auxiliary wheel 21 can ensure the stability of the automatic guided vehicle body 1 during the movement, and the automatic guided vehicle body 1 moves along the track set on the ground and the path planned by the system. When the automatic guided vehicle body 1 moves to the bottom of the book shelf, the hydraulic cylinder 3 is started at this time, and the output shaft of the hydraulic cylinder 3 drives the lifting plate 31 to move upward, and the upper surface of the lifting plate 31 is The surface will conflict with the bottom of the book shelf, and then the book shelf can be lifted. The automatic guided vehicle body 1 can move the book shelf to the designated transfer position according to the track set on the ground and the planned path. When the book shelf reaches the transfer position, the output shaft of the hydraulic cylinder 3 contracts, causing the lifting plate 31 to move downward. The top of the lifting plate 31 cannot conflict with the bottom of the book shelf. The automatic guided vehicle body 1 can move out of the bottom of the book shelf at this time, and repeat the above steps for other books and periodicals for transfer. The above is the operating principle of the existing automatic guided vehicle body 1.

[0046] Correction of bookshelves by correction components:

[0047] When the output shaft of the hydraulic cylinder 3 drives the lifting plate 31 to move upward, the groove of the lifting plate 31 drives the contact plate 45 to move upward synchronously through the first spring 44. The contact plate 45 will first hit the bottom of the book shelf. At this time, the contact plate 45 cannot move upward after being hit by the book shelf. When the lifting plate 31 continues to move upward, the first spring 44 will be compressed. The lifting plate 31 will synchronously drive the correction plate 42 to move upward through the sliding groove 41. The correction plate 42 drives the pushing plate 43 to move upward synchronously. Because the contact plate 45 cannot move upward, the pushing rod 46 cannot move upward at the same time. During the upward movement, its inclined surface will be pushed by the bending part at the bottom of the pushing rod 46, so that the pushing plate 43 drives the correction plate 42 to converge toward the middle in the sliding groove 41. During the process of the correction plate 42 converging inwardly, it can conflict with the bottom shelf board of the book shelf. The correction plate 42 converges toward the middle to clamp the shelf board of the book shelf. The plane of the correction plate 42 contacts the plane of the book shelf to push the lighter book shelf parallel to the correction plate 42, avoiding the unstable center of gravity during the subsequent transportation of the book shelf due to the misalignment between the book shelf and the automatic guided vehicle body 1, thereby improving the stability of the book shelf during transportation.

[0048] The protective components protect both sides of the bookshelf:

[0049] When the top of the lifting plate 31 collides with the bottom of the bookshelf, the multi-section electric telescopic rod 52 is activated, and the extension of the telescopic axis of the multi-section electric telescopic rod 52 causes the two protection frames 53 on the same side to move to the side away from the fixed plate 51, and the protection frames 53 drive the guide rod 56 to move in the guide groove 54 to the side close to the convex tooth 55, and the guide rod 56 drives the gear 57 to move synchronously in the guide groove 54. When the gear 57 moves to the meshing position with the convex tooth 55, the end of the protection frame 53 close to the multi-section electric telescopic rod 52 has moved out of the bottom range of the lifting plate 31, that is, the protection frame 53 is no longer located at Under the lifting plate 31, after the gear 57 continues to move, it will engage with the convex tooth 55 and rotate. The gear 57 drives the protective frame 53 to rotate through the guide rod 56. At this time, the protective frame 53 will be folded upward into a vertical shape with the guide rod 56 as the axis. The vertical protective frame 53 can protect both sides of the book shelf to avoid skewing caused by excessive shaking during transportation. In addition, it can also protect the books and periodicals on the book shelf to prevent them from falling during transportation. At the same time, it can also prevent the book shelf from touching other objects during transportation and causing the book shelf to skew, thereby improving the safety of the book shelf during transportation.

[0050] The support components support the tilted bookshelf:

[0051] After the above-mentioned middle protective frame 53 is folded into a vertical shape, the retraction groove 61 provided thereon faces outward, that is, away from the side of the lifting plate 31. When the book shelf is transported by the automatic guided vehicle body 1 on the track, because the automatic guided vehicle body 1 needs to move according to the track, when the automatic guided vehicle body 1 moves to the bend of the track, it needs to pause and then turn before it can move. In this process, it needs to pause and then move. The book shelf is prone to shaking due to inertia. If the book shelf is heavy, the inertia is large, which is easy to cause shaking. If the shaking amplitude is large, it is easy to cause collapse. Before the collapse, the book shelf will tilt first, and the built-in tilt detector will detect the tilt angle of the book shelf. If the tilt angle is too large, the tilt detector will detect it and cooperate with the external The controller controls the electric rotating shaft 62 to rotate, and the electric rotating shaft 62 drives the first support rod 63 to swing to the side away from the retraction groove 61. When the first support rod 63 drives the second support rod 67 therein to swing outward, the end of the second support rod 67 away from the second spring 66 cannot conflict with the groove wall of the retraction groove 61. The swinging angle of the first support rod 63 here only makes the second support rod 67 break away from the contact with the retraction groove 61. Under the elastic restoring action of the second spring 66, the second support rod 67 is pushed to slide in the movable groove 64 to the side away from the electric rotating shaft 62, that is, the second support rod 67 slides to the outside of the movable groove 64. In this process, the second support rod 67 will drive the block 610 to move synchronously through the card slot 68. At this time, the block 610 will move to the right, that is, Figure 8On the right side shown in the figure, when the block 610 moves to the position overlapping with the positioning hole 65, the elastic reset of the third spring 69 will push the block 610 into the positioning hole 65, but under the continuous reset action of the second spring 66, the second support rod 67 will also continue to move. During this process, the inclined surface of the block 610 will contact the notch of the positioning hole 65, so that the block 610 moves into the slot 68 again and compresses the third spring 69, and so on. When the second support rod 67 contacts the ground, the second support rod 67 no longer slides. If the block 610 just coincides with the positioning hole 65 at this time, that is, the block 610 enters the positioning hole 65 under the elastic reset action of the third spring 69, the plane of the block 610 will contact the positioning hole 65, limiting the leftward movement of the second support rod 67, that is, Figure 8 As shown on the left side, in addition, if the block 610 does not coincide with the positioning hole 65, that is, when the second support rod 67 cannot move after contacting the ground, the protection frame 53 will tilt downward again due to the inclination of the shelf. At this time, the protection frame 53 will drive the first support rod 63 to move downward through the electric shaft 62, and the first support rod 63 will make the positioning hole 65 coincide with the block 610. Under the elastic reset action of the third spring 69, the block 610 enters the positioning hole 65, and the plane of the block 610 contacts the positioning hole 65, thereby limiting the movement of the second support rod 67. The locking and fixing of the second support rod 67 after extension can support the inclined book shelf and the automatic guided vehicle body 1, prevent the book shelf from continuing to tilt and collapse, and thus prevent the collapsed book shelf from colliding with other surrounding shelves, and avoid damaging other automatic guided vehicle bodies 1.

[0052] The extension of the second support rod 67 on the other side and the swing of the first support rod 63 can be ignored. After the above-mentioned support assembly supports the book shelf, the staff can straighten the book shelf and reset the structure inside the support assembly. The resetting operation of the support assembly is: first manually press the block 610 so that the block 610 cannot be engaged with the positioning hole 65, and then push the second support rod 67 into the movable groove 64. At this time, the second spring 66 will be compressed by the second support rod 67, and then push the first support rod 63 to move into the retraction groove 61, and make the second support rod 67 conflict with the groove wall of the movable groove 64, and finally start the automatic guided vehicle body 1 again to transport the book shelf.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
