DETAILED DESCRIPTION

[0025] 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.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Figure 1 to Figure 7 The structure of a transportation loading and unloading device according to one embodiment of the present invention is schematically shown.

[0028] like Figure 1 to Figure 7 As shown, a transportation loading and unloading device includes a grabbing device 1, a first transmission device 2, a lifting device 3 and a second transmission device 4.

[0029] like Figure 1 and Figure 2 As shown, a lifting mechanism 5 is installed between the lifting device 3 and the second transmission device 4, and the grabbing device 1 is installed on the right side of the first transmission device 2. When the grabbing device 1 is started, the grabbing device 1 can grab the goods 61 on the transportation vehicle, and then the grabbing device 1 places the goods 61 on the first transmission device 2. The grabbing device 1 in this embodiment can be connected to the gantry 15. The gantry 15 is an existing device. The gantry 15 can drive the grabbing device 1 to move in three-dimensional directions. The three-dimensional directions mentioned here refer to Figure 1 In the six directions shown, namely, front, back, left, right, up and down, the gantry 15 can drive the grabbing device 1 to move to the cargo 61 to be grabbed, and then the grabbing device 1 grabs the cargo.

[0030] After the grabbing device 1 grabs the goods 61 and places it on the first transmission device 2, the first transmission device 2 can transfer the goods 61 to the lifting device 3. After the lifting device 3 is started, the lifting device 3 can circulate and lift the goods 61 to the lifting mechanism 5. The lifting mechanism 5 tilts and lifts the goods 61 and slides it to the second transmission device 4. The second transmission device 4 transmits the goods 61 to the designated position. The designated position mentioned here can be a warehouse or a device to be processed.

[0031] The structure of the grabbing device 1 is described in detail below. Figure 4 to Figure 7 As shown, the grasping device 1 in this embodiment includes a base 11 , a plurality of claws 12 , a moving base 13 and a rotating connecting rod 14 .

[0032] like Figure 4 and Figure 5 As shown, the upper end of the claw 12 is rotatably connected to the movable seat 13 (e.g., a rotatable connection is formed by a rotating shaft), the lower end of the claw 12 is rotatably connected to the base 11 (e.g., a rotatable connection is formed by a rotating shaft), and the lower end of the claw 12 also extends downward. When multiple claws 12 act simultaneously, multiple claws 12 can clamp or release the cargo 61.

[0033] The movable seat 13 in this embodiment is movably connected to the base 11, for example, a slide groove 110 can be formed on the base 11, and a slide rail can be formed on the outer wall of the movable seat 13. The movable seat 13 can be movably connected to the base 11 through the slide groove 110 and the slide rail. Therefore, the movable seat 13 can move along the base 11, and the upper end of the rotating connecting rod 14 is connected to the movable seat 13. During the rising and falling process of the movable seat 13, the movable seat 13 can drive the rotating connecting rod 14 to move up and down and rotate, and the lower end of the rotating connecting rod 14 can be stuck on the base 11. Of course, the lower end of the rotating connecting rod 14 can also be detached from the base 11, and the claw 12 can be stuck or released by moving the rotating connecting rod 14 up and down and rotating it; when the lower end of the rotating connecting rod 14 is stuck on the base 11 , the upper end of the rotating connecting rod 14 will pull the moving seat 13, making the moving seat 13 unable to continue to move upward. At this time, the moving seat 13 cannot continue to pull the upper end of the claw 12 upward, and the lower end of the claw 12 cannot continue to rotate to a position close to the center of the base 11, and multiple claws 12 cannot clamp the cargo 61. When the lower end of the rotating connecting rod 14 is detached from the base 11, the upper end of the rotating connecting rod 14 will not pull the moving seat 13 (that is, the upper end of the rotating connecting rod 14 has no force on the moving seat 13), and the moving seat 13 can move upward a certain distance. At this time, the moving seat 13 will also pull the upper end of the claw 12 upward, and the lower end of the claw 12 will correspondingly rotate to a position close to the center of the base 11. Multiple claws 12 can clamp the flange of the cargo. At this time, the claw 12 can clamp the cargo 61.

[0034] like Figure 4 and Figure 5 As shown, the claw 12 in this embodiment includes a connecting rod 121 and a clamping member 122. The upper end of the connecting rod 121 is rotatably connected to the movable seat 13 (e.g., through a rotating shaft to achieve a rotatable connection), the lower end of the connecting rod 121 is rotatably connected to the upper end of the clamping member 122 (e.g., through a rotating shaft to achieve a rotatable connection), the lower end of the clamping member 122 is rotatably connected to the base 11, the lower end of the clamping member 122 extends downward, and an inward recess 1221 is formed. When the recesses 1221 of multiple clamping members 122 act at the same time (i.e., after the multiple clamping members 122 rotate a certain angle toward the center of the base 11), the cargo 61 can be clamped.

[0035] like Figure 4 and Figure 5 As shown, a receiving space 133 is integrally formed on the movable seat 13, and the upper end of the rotating connecting rod 14 is installed in the receiving space 133. A first guide portion 131 is provided at the upper portion of the receiving space 133, and a second guide portion 132 is provided at the lower portion of the receiving space 133. There are four first guide portions 131 and four second guide portions 132, and the four first guide portions 131 are connected end to end. Similarly, there are four second guide portions 132, and the four second guide portions 132 are connected end to end, and the first guide portions 131 and the second guide portions 132 are staggered. The first guide portions 131 and the second guide portions 132 have the same shape, both of which are arc-shaped portions. The first guide portions 131 and the second guide portions 132 are both formed with a raised triangular shape, and the first guide portions 131 and the second guide portions 132 are integral with the movable seat 13.

[0036] like Figure 4 and Figure 5 It can be seen that when the movable seat 13 moves downward together with the first guide portion 131, it can push the rotating connecting rod 14 to rotate a set angle (such as 90°). After that, the movable seat 13 moves upward, so that the upper end of the rotating connecting rod 14 is stuck on another second guide portion 132, and the lower end of the rotating connecting rod 14 can be stuck on the base 11, or the lower end of the rotating connecting rod 14 can be detached from the base 11.

[0037] The specific structure of the rotating connecting rod 14 is as follows: Figure 4 to Figure 7 As shown, a protruding rod 141 is integrally formed at the upper end of the rotating connecting rod 14, and the protruding rod 141 can extend out of the accommodating space 133. The protruding rod 141 cooperates with the first guide portion 131 and the second guide portion 132, and a supporting member 142 is integrally formed at the lower end of the rotating connecting rod 14. A through hole 111 is provided at the corresponding position of the base 11, and the supporting member 142 can extend into the through hole 111 and be connected to the base 11, or the supporting member 142 can be moved out from the through hole 111.

[0038] In addition, the gripping device 1 further includes a gantry 15 and a lifting cylinder 16. The base 11 is connected to the gantry 15. The gantry 15 can drive the base 11 to move in three dimensions. The lifting cylinder 16 is mounted on the gantry 15, and the output end of the lifting cylinder 16 is connected to the moving base 13. Since the gantry 15 is an existing device, its specific structure is not described in detail.

[0039] The overall working process of the grabbing device 1 is described in detail below: a support plate is integrally installed on the base 11, and the support plate can support the lower end of the rotating connecting rod 14, so that the rotating connecting rod 14 cannot move downward all the time. When the grabbing device 1 is driven to move above the goods through the gantry 15, the gantry 15 drives the grabbing device 1 to move downward until the base 11 is against the goods, and then the lifting cylinder 16 is started. Figure 4 As shown, the lifting cylinder 16 drives the moving seat 13 to move downward along the base 11. During the downward movement of the moving seat 13, the first guide portion 131 on the moving seat 13 will move downward synchronously. The first guide portion 131 is arc-shaped, and the first guide portion 131 has a raised triangular shape. Since the first guide portion 131 and the second guide portion 132 are staggered, after the first guide portion 131 moves a certain distance, since the lower end of the rotating connecting rod 14 is supported by the support plate of the base 11, the first guide portion 131 can just abut against the convex rod 141. Figure 4 and Figure 5 The first guide portion 131 in the middle continues to move downward, and the first guide portion 131 will push the protruding rod 141 to the left to rotate. At this time, looking from the top down, the rotating connecting rod 14 will rotate clockwise. When the first guide portion 131 moves to the bottom, the protruding rod 141 is driven by the inclined portion of the first guide portion 131 and rotates a certain angle, so that the protruding rod 141 is located at Figure 4 As shown in the left recess of the first guide portion 131, at this time, the lifting cylinder 16 drives the movable seat 13 to move upward, the first guide portion 131 and the second guide portion 132 will move upward synchronously, and the raised triangle shape of the other second guide portion 132 will push the protruding rod 141 to move obliquely to the left and rotate. At this time, looking from top to bottom, the rotating connecting rod 14 will rotate clockwise at a certain angle.

[0040] Therefore, the rotating connecting rod 14 is driven by the first guide portion 131 and the second guide portion 132 to rotate twice, and the angle of the rotating connecting rod 14 rotating twice is 90°. Figure 4 to Figure 7The rotating abutment member 142 shown will not be abutted by the through hole 111, the abutment member 142 of the connecting rod 14 can be moved out of the through hole 111, and the abutment member 142 will not have any contact with the base 111. When the lifting cylinder 16 drives the moving seat 13 to continue to move upward, the upper end of the connecting rod 121 of the claw 12 moves upward, and the connecting rod 121 rotates, and the upper end of the clamping member 122 of the corresponding claw 12 is lifted upward, and the lower end of the clamping member 122 will rotate inward, and the space formed by the clamping members 122 of multiple claws 12 will become smaller, and multiple clamping members 122 will clamp the flange of the goods.

[0041] A plurality of claws 12 can pull up the cargo, and then the gantry 15 drives the grabbing device 1 to move to the first transmission device 2, and the above-mentioned action is repeated again, and the moving seat 13 moves downward along the base 11. During the downward movement of the moving seat 13, the first guide portion 131 on the moving seat 13 will move downward synchronously, and the first guide portion 131 can push the protruding rod 141 to move obliquely to the left and rotate. Looking from top to bottom, the rotating connecting rod 14 will rotate clockwise. When the first guide portion 131 moves to the bottom, the moving seat 13 moves upward, and the first guide portion 131 and the second guide portion 132 will move upward synchronously, and the other first guide portion 131 and the second guide portion 132 will move upward synchronously. The second guide portion 132 pushes the protruding rod 141 to move and rotate obliquely to the left again, and the rotating connecting rod 14 rotates 90° again. At this time, the abutment 142 will be abutted by the through hole 111, and the abutment 142 of the rotating connecting rod 14 cannot be moved out of the through hole 111. The abutment 142 will pull the base 111, and when the lifting cylinder 16 drives the moving seat 13 to move upward, the moving seat 13 cannot move along the base 111, that is, the lower end of the clamping member 122 will not continue to rotate inward. At this time, the inward rotation angle of the claw 12 is small, and the clamping members 122 of multiple claws 12 are wider, and multiple claws 12 cannot clamp the flange of the goods.

[0042] In this embodiment, Figure 1 and Figure 2 As shown, the first transmission device 2 includes three belt transmission devices, which are arranged in parallel, and a gap is formed between two adjacent belt transmission devices. The belt transmission device includes a first driving wheel, a first belt and a first driven wheel connected to each other, and the second transmission device 4 includes a second driving wheel, a second belt and a second driven wheel connected to each other. Since the belt transmission method is a conventional method, the specific connection method is not repeated here.

[0043] The lifting device 3 in this embodiment includes a transmission chain 31, a fixed seat 32 and a lifting fork plate 33. The transmission chain 31 can be reciprocated, the fixed seat 32 can be installed on the transmission chain 31, the lifting fork plate 33 is rotatably connected with the fixed seat 32, and a positioning rod can be provided on the back of the lifting fork plate 33. The positioning rod can make the lifting fork plate 33 always in a horizontal state during the transmission process. The lifting fork plate 33 is a grid-like structure. Figure 3 It can be seen that the structure of the lifting fork plate 33 matches the three belt transmission devices. Therefore, the lifting fork plate 33 can pass through the three belt transmission devices. The lifting fork plate 33 lifts the goods 61 on the belt transmission devices. During the reciprocating transmission of the lifting fork plate 33, the goods 61 will also be placed on the lifting mechanism 5.

[0044] like Figure 3 As shown, the structure of the lifting mechanism 5 is as follows: the lifting mechanism 5 includes a grid plate 51 and a cylinder 52, one end of the grid plate 51 is installed on the second transmission device 4, and the cylinder 52 is connected to the other end of the grid plate 51. When the cylinder 52 is started, the cylinder 52 can lift the other end of the grid plate 51 so that the cargo 61 slides onto the second transmission device 4 under the action of gravity.

[0045] The present invention further comprises a transport vehicle 6 on which cargo 61 can be placed, and a flange is provided at the upper end of the cargo 61.

[0046] When the transport vehicle 6 of the present invention is to unload the cargo 61, the grabbing device 1 can grab the cargo 61 on the transport vehicle and place the cargo 61 on the first transmission device 2. The first transmission device 2 transmits the cargo 61 to the lifting device 3. The lifting device 3 circulates and lifts the cargo 61 to the lifting mechanism 5. The lifting mechanism 5 lifts the cargo 61 and enters the second transmission device 4. The second transmission device 4 transmits the cargo 61 to the designated position. The whole process does not require human participation and can complete automatic unloading. At the same time, when loading, only the reverse operation is required to put the cargo 61 on the transport vehicle 6. After completion, the transport vehicle 6 transports the cargo 61 to the designated position and then unloads.

[0047] Through the present invention, automatic loading and unloading can be completed. Compared with the traditional loading and unloading methods, the present invention can be set at a dedicated location, and then the goods 61 can be transferred to the designated location. It does not occupy the employee's activity area, avoids the occurrence of danger, and the whole process is efficient.

[0048] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
