Description

Technical Field

[0001] This invention relates to a loading and unloading device, and more particularly to a loading and unloading device for transportation. Background Technology

[0002] When transporting goods, loading and unloading are necessary. Currently, loading and unloading are generally accomplished in the following way: workers drive forklifts to lift the goods, the forklifts move the goods to trucks, and the trucks transport the goods to the designated location. When unloading, forklifts are also used to lift the goods and then transport them to the designated location.

[0003] If the above unloading method is used during the unloading process of trucks in transportation, the following problems will be encountered: Since the forklift does not travel along the prescribed path, there will be significant safety hazards. In addition, the transportation and loading / unloading process requires the cooperation and command of multiple personnel, resulting in low overall efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a loading and unloading device for transportation to solve the problems existing in the prior art.

[0005] According to one aspect of the present invention, a transportation loading and unloading device is provided, comprising a gripping device, a first transmission device, a lifting device, and a second transmission device. A lifting mechanism is provided between the lifting device and the second transmission device. The gripping device is located on one side of the first transmission device. The gripping device grips goods on a transportation vehicle and places the goods on the first transmission device. The first transmission device transmits the goods to the lifting device. The lifting device cyclically lifts the goods to the lifting mechanism. The lifting mechanism lifts the goods and enters the second transmission device. The second transmission device transmits the goods to a designated position.

[0006] In some embodiments, the gripping device includes a base, multiple grippers, a movable seat, and a rotating connecting rod. One end of the gripper is rotatably connected to the movable seat, and the other end of the gripper is rotatably connected to the base. The other end of the gripper also extends downward and can grip or release the goods. The movable seat is movably connected to the base. The upper end of the rotating connecting rod is connected to the movable seat, and the movable seat can drive the rotating connecting rod to move and rotate. The lower end of the rotating connecting rod can be gripped on the base, or the lower end of the rotating connecting rod can be detached from the base. When the lower end of the rotating connecting rod is gripped on the base, the gripper cannot grip the goods; when the lower end of the rotating connecting rod is detached from the base, the gripper can grip the goods.

[0007] In some embodiments, the gripper includes a connecting rod and a clamping element. The upper end of the connecting rod is rotatably connected to the movable seat, the lower end of the connecting rod is rotatably connected to the upper end of the clamping element, and the lower end of the clamping element is rotatably connected to the base. The lower end of the clamping element is also provided with an inward recess that can clamp the goods.

[0008] In some embodiments, the movable seat is provided with a receiving space, the upper end of the rotating connecting rod is provided in the receiving space, the upper part of the receiving space is provided with a first guide part, and the lower part of the receiving space is provided with a second guide part. Both the first guide part and the second guide part are arc-shaped. When the movable seat moves downward together with the first guide part, it can push the rotating connecting rod to rotate by a set angle, so that the lower end of the rotating connecting rod can be locked on the base, or the lower end of the rotating connecting rod can be disengaged from the base.

[0009] In some embodiments, the upper end of the rotating connecting rod is provided with a protrusion that can cooperate with the first guide part and the second guide part, and the lower end of the rotating connecting rod is provided with a stop member. The corresponding position of the base is provided with a through hole. The stop member can extend into the through hole and connect with the base, or the stop member can be moved out of the through hole. The first guide part and the second guide part are arranged alternately.

[0010] In some embodiments, the gripping device further includes a gantry and a lifting cylinder, with a base connected to the gantry and the gantry capable of moving the base in three dimensions. The lifting cylinder is mounted on the gantry and its output end is connected to the moving base.

[0011] In some embodiments, the first transmission device includes three belt drive devices arranged in parallel to each other, with a gap between adjacent belt drive devices. Each belt drive device includes a first driving pulley, a first belt, and a first driven pulley connected to each other. The second transmission device includes a second driving pulley, a second belt, and a second driven pulley connected to each other.

[0012] In some embodiments, the lifting device includes a drive chain, a fixed seat, and a lifting fork plate. The drive chain is capable of reciprocating transmission, the fixed seat is mounted on the drive chain, and the lifting fork plate is rotatably connected to the fixed seat. The lifting fork plate has a grid-like structure and can pass through three belt drive devices to lift the goods on the belt drive devices. During the reciprocating transmission of the lifting fork plate, the goods are also placed on the lifting mechanism.

[0013] In some embodiments, the lifting mechanism includes a grid plate and a cylinder, one end of which is located at a second transmission device, and the cylinder is connected to the other end of the grid plate and can tilt and lift the other end of the grid plate so that the goods slide onto the second transmission device.

[0014] In some embodiments, a transport vehicle is also included, on which the goods can be placed, and the upper end of the goods is provided with a flange.

[0015] The beneficial effects of this invention are as follows: When the transport vehicle needs to unload goods, the gripping device can grip the goods on the transport vehicle and place them on the first transmission device. The first transmission device transmits the goods to the lifting device, which then cyclically lifts the goods to the hoisting mechanism. The hoisting mechanism tilts and lifts the goods and sends them to the second transmission device, which then transmits the goods to the designated position. The entire process requires no manual intervention and can complete automatic unloading. When loading, the reverse operation is performed to place the goods onto the transport vehicle. After loading, the transport vehicle transports the goods to the designated position and then unloads them.

[0016] This invention enables automated loading and unloading. Compared to traditional loading and unloading methods, this invention can be set up in a dedicated location to transport goods to a designated location without occupying the activity area of ​​employees, thus avoiding the occurrence of dangers, and the whole process is highly efficient.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort 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 commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Figures 1 to 7 The diagram schematically illustrates the structure of a transportation loading and unloading device according to one embodiment of the present invention.

[0028] like Figures 1 to 7 As shown, a transportation loading and unloading device includes a gripping 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. The gripping device 1 is installed on the right side of the first transmission device 2. When the gripping device 1 is activated, it can grip the goods 61 on the transport vehicle. Then, the gripping device 1 places the goods 61 onto the first transmission device 2. In this embodiment, the gripping device 1 can be connected to a gantry 15. The gantry 15 is an existing device that allows the gripping device 1 to move in three dimensions. The three dimensions referred to here are as follows: Figure 1 The six directions shown (front, back, left, right, up, down) can be used to move the gripping device 1 to the cargo 61 to be gripped via the gantry frame 15, after which the gripping device 1 grips the cargo.

[0030] After the gripping device 1 grips the goods 61 and places them 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 cyclically lift the goods 61 to the lifting mechanism 5. The lifting mechanism 5 tilts and lifts the goods 61 and slides them down to the second transmission device 4. The second transmission device 4 transmits the goods 61 to the designated position, which can be a warehouse or the processing device.

[0031] The structure of the gripping device 1 will be described in detail below, such as Figures 4-7 As shown, the gripping device 1 in this embodiment includes a base 11, multiple claws 12, a movable seat 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., through a rotating shaft to form a rotatable connection), and the lower end of the claw 12 is rotatably connected to the base 11 (e.g., through a rotating shaft to form a rotatable connection). The lower end of the claw 12 also extends downward. When multiple claws 12 act simultaneously, multiple claws 12 can clamp or release the goods 61.

[0033] In this embodiment, the movable seat 13 and the base 11 are movably connected. For example, a 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 groove 110 and the slide rail. Therefore, the movable seat 13 can move along the base 11. The upper end of the rotating connecting rod 14 is connected to the movable seat 13. During the rising and falling process, the movable seat 13 can drive the rotating connecting rod 14 to move up and down and rotate. The lower end of the rotating connecting rod 14 can be locked on the base 11. Of course, the lower end of the rotating connecting rod 14 can also be disengaged from the base 11. The up and down movement and rotation of the rotating connecting rod 14 can cause the chuck 12 to lock or release the goods 61. When the lower end of the rotating connecting rod 14 is locked on the base 11... When the upper end of the rotating connecting rod 14 pulls the movable seat 13, it prevents the movable seat 13 from moving upward. At this time, the movable seat 13 cannot pull the upper end of the chuck 12 upward, and the lower end of the chuck 12 cannot continue to rotate towards the center of the base 11. The multiple chucks 12 cannot hold the goods 61. When the lower end of the rotating connecting rod 14 is disengaged from the base 11, the upper end of the rotating connecting rod 14 will not pull the movable seat 13 (i.e., the upper end of the rotating connecting rod 14 has no force on the movable seat 13). The movable seat 13 can move upward a certain distance. At this time, the movable seat 13 will also pull the upper end of the chuck 12 upward, and the lower end of the chuck 12 will rotate towards the center of the base 11. The multiple chucks 12 can hold the flange of the goods. At this time, the chuck 12 can hold the goods 61.

[0034] like Figure 4 and Figure 5 As shown, the claw 12 in this embodiment includes a connecting rod 121 and a locking member 122. The upper end of the connecting rod 121 is rotatably connected to the movable seat 13 (e.g., through a rotating shaft). The lower end of the connecting rod 121 is rotatably connected to the upper end of the locking member 122 (e.g., through a rotating shaft). The lower end of the locking member 122 is rotatably connected to the base 11. The lower end of the locking member 122 extends downward and forms an inwardly recessed portion 1221. When the recesses 1221 of multiple locking members 122 act simultaneously (i.e., after multiple locking members 122 rotate a certain angle toward the center of the base 11), they can lock the goods 61.

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

[0036] like Figure 4 and Figure 5 As can be seen, when the movable seat 13 and the first guide part 131 move downward, they can push the rotating connecting rod 14 to rotate by a set angle (e.g., 90°). Then, the movable seat 13 moves upward, so that the upper end of the rotating connecting rod 14 is locked on another second guide part 132, and the lower end of the rotating connecting rod 14 can be locked on the base 11, or the lower end of the rotating connecting rod 14 can be disengaged from the base 11.

[0037] The specific structure of the rotating connecting rod 14 is as follows, such as Figures 4-7 As shown, the upper end of the rotating connecting rod 14 is integrally formed with a protrusion 141, which can extend out of the receiving space 133. The protrusion 141 cooperates with the first guide part 131 and the second guide part 132. The lower end of the rotating connecting rod 14 is integrally formed with a stop member 142. The base 11 is provided with a through hole 111 at the corresponding position. The stop member 142 can extend into the through hole 111 and connect with the base 11, or the stop member 142 can be moved out of the through hole 111.

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

[0039] The following is a detailed description of the overall working process of the gripping device 1: A support plate is integrally installed on the base 11. The support plate supports the lower end of the rotating connecting rod 14, preventing the rotating connecting rod 14 from moving downwards continuously. When the gripping device 1 is moved above the goods by the gantry frame 15, the gantry frame 15 moves the gripping device 1 downwards until the base 11 touches the goods. After that, the lifting cylinder 16 is activated. Figure 4 As shown, the lifting cylinder 16 drives the movable seat 13 to move downward along the base 11. During the downward movement of the movable seat 13, the first guide part 131 on the movable seat 13 moves downward synchronously. The first guide part 131 is arc-shaped and has a protruding triangular shape. Since the first guide part 131 and the second guide part 132 are staggered, after the first guide part 131 moves a certain distance, the lower end of the rotating connecting rod 14 is supported by the support plate of the base 11. Therefore, the first guide part 131 can just abut against the protruding rod 141. Figure 4 and Figure 5 As the first guide portion 131 continues to move downwards, it pushes the protruding rod 141 to the left to rotate. At this point, viewed from above, the rotating connecting rod 14 rotates clockwise. When the first guide portion 131 reaches its lowest point, the protruding rod 141 is driven by the inclined portion of the first guide portion 131 and rotates at a certain angle, causing the protruding rod 141 to be positioned... Figure 4 The left side of the first guide part 131 is recessed. At this time, the lifting cylinder 16 drives the moving seat 13 to move upward. The first guide part 131 and the second guide part 132 will move upward synchronously. The protruding triangular shape of the other second guide part 132 will push the protruding rod 141 to move and rotate obliquely to the left. At this time, looking from above, the rotating connecting rod 14 will rotate clockwise by a certain angle.

[0040] Therefore, driven by the first guide part 131 and the second guide part 132, the rotating connecting rod 14 rotates twice, and the angle of the two rotations of the rotating connecting rod 14 is 90°. At this time, Figures 4-7The rotating abutment 142 shown will not be blocked by the through hole 111. The abutment 142 of the connecting rod 14 can be moved out of the through hole 111. The abutment 142 will not have any contact with the base 111. During the process of the lifting cylinder 16 driving 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. The upper end of the corresponding claw 122 of the claw 12 is lifted upward and the lower end of the claw 122 will rotate inward. The space formed by the claws 122 of the claw 12 will become smaller and the multiple claws 122 will lock the flange of the goods.

[0041] Multiple grippers 12 can lift the goods, and then the gantry frame 15 drives the gripping device 1 to move to the first transmission device 2, repeating the above actions. The moving seat 13 moves downward along the base 11. During the downward movement of the moving seat 13, the first guide part 131 on the moving seat 13 will move downward synchronously. The first guide part 131 can push the protruding rod 141 to move and rotate diagonally to the left. Looking from above, the rotating connecting rod 14 will rotate clockwise. When the first guide part 131 moves to the bottom, the moving seat 13 moves upward, and the first guide part 131 and the second guide part 132 will move upward synchronously. The second guide part 132 then pushes the protruding rod 141 to move and rotate diagonally to the left again. The rotating connecting rod 14 rotates 90° again. At this time, the abutment 142 will be blocked by the through hole 111. 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. 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 clamp 122 will not continue to rotate inward. At this time, the inward rotation angle of the claw 12 is small. The clamping parts 122 of the multiple claws 12 are wide. The multiple claws 12 cannot clamp the flange of the goods.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, the first transmission device 2 includes three belt drive devices arranged in parallel, with gaps between adjacent belt drive devices. Each belt drive device includes a first driving pulley, a first belt, and a first driven pulley connected to each other. The second transmission device 4 includes a second driving pulley, a second belt, and a second driven pulley connected to each other. Since belt drive is a conventional method, the specific connection method will not be described in detail.

[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 is capable of reciprocating transmission. The fixed seat 32 can be mounted on the transmission chain 31. The lifting fork plate 33 is rotatably connected to the fixed seat 32, and a positioning rod can be provided on the back of the lifting fork plate 33. The positioning rod ensures that the lifting fork plate 33 remains horizontal during transmission. The lifting fork plate 33 has a grid-like structure. Figure 3 As can be seen, the structure of the lifting fork plate 33 is matched with the three belt drive devices. Therefore, the lifting fork plate 33 can pass through the three belt drive devices. The lifting fork plate 33 lifts the goods 61 on the belt drive devices. During the reciprocating transmission of the lifting fork plate 33, it will also place the goods 61 on the lifting mechanism 5.

[0044] like Figure 3 As shown, the lifting mechanism 5 has the following structure: The lifting mechanism 5 includes a grid plate 51 and a cylinder 52. One end of the grid plate 51 is installed at 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 down onto the second transmission device 4 under the action of gravity.

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

[0046] When the transport vehicle 6 of the present invention needs to unload cargo 61, the gripping device 1 can grip 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 cyclically lifts the cargo 61 to the hoisting mechanism 5. The hoisting 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 entire process requires no human intervention and can complete automatic unloading. At the same time, when loading, only the reverse operation is needed to put the cargo 61 into the transport vehicle 6. After completion, the transport vehicle 6 transports the cargo 61 to the designated position and then unloads it.

[0047] This invention enables automated loading and unloading. Compared to traditional loading and unloading methods, this invention can be set up in a dedicated location and then the goods 61 can be transferred to the designated location without occupying the activity area of ​​employees, avoiding the occurrence of dangers, and the whole process is highly efficient.

[0048] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
