Description

Technical Field

[0001] This invention relates to the technical field of logistics and express delivery, and specifically to a gripping device for logistics and express delivery. Background Technology

[0002] With the rapid development of the e-commerce industry, the volume of logistics and express delivery services has exploded, placing extremely high demands on the automation level and efficiency of express sorting and transfer. In logistics and express warehousing and sorting scenarios, the gripping device, as one of the core pieces of equipment, undertakes the important task of transferring express packages from one workstation to another. Its operational stability, gripping reliability, and operational efficiency directly affect the smoothness of the entire logistics chain.

[0003] Currently, existing logistics and express delivery gripping devices generally have shortcomings. Most existing devices adopt a structure of unidirectional clamping or symmetrical cylinders directly driving the clamping plate. Unidirectional clamping is difficult to adapt to express delivery of different sizes and shapes, and uneven clamping force can easily lead to deformation or slippage of the express delivery. Although the symmetrical cylinder driving method can achieve bidirectional clamping, the synchronization of the two cylinders is difficult to control precisely, which can easily lead to clamping deviation. Moreover, the contact parts between the clamping plate and the express delivery are mostly planar rigid structures, lacking targeted anti-slip and anti-rotation designs. For express delivery with smooth surfaces and irregular shapes, the clamping reliability is extremely poor, and it is easy for the express delivery to rotate or slip during transportation, causing damage to the express delivery or interruption of operations. Summary of the Invention

[0004] The purpose of this invention is to provide a gripping device for logistics and express delivery, so as to overcome the above-mentioned defects in the prior art.

[0005] A gripping device for logistics and express delivery includes a support frame, a translation mechanism, a lifting mechanism, and a gripping mechanism. The translation mechanism is mounted on the support frame and is used to drive the movable frame on it to move on it. The lifting mechanism is mounted on the mobile frame and drives the gripping mechanism on it to move up and down.

[0006] Preferably, the translation mechanism includes a motor and a chain. Sprockets are rotatably connected to both sides of one end of the support frame via a rotating shaft. Sprockets are rotatably connected to both sides of the other end of the support frame via a rotating shaft. The motor is mounted on the support frame and its output shaft is connected to the rotating shaft. Sprockets on the same side are connected to each other via a chain. Both sides of the moving frame are connected to the corresponding chains.

[0007] Preferably, the lifting mechanism includes a lifting frame, a second chain, a second motor, a third sprocket, and a tensioning sprocket. The lifting frame is slidably connected to the movable frame. The two ends of the second chain are respectively connected to the upper and lower ends of the lifting frame. The second motor is mounted on the movable frame, and a third sprocket that meshes with the second chain is mounted on its output shaft. The tensioning sprocket is rotatably connected to the movable frame and meshes with the second chain.

[0008] Preferably, the gripping mechanism includes a gear disk, a motor, a clamping plate, a rack, a moving gear, and a cylinder. The gear disk is rotatably connected to the lower end of the lifting frame. The motor is mounted on the lifting frame, and a drive gear that meshes with the gear disk is mounted on its output shaft. A mounting frame is provided below the gear disk. Two guide rods are provided parallel to each other on the upper and lower sides of the mounting frame in a cross shape. The two guide rods on the same horizontal plane are slidably connected to the two ends of the clamping plates. A rack is provided on the two clamping plates on the same guide rod. The moving gear is rotatably connected to the mounting frame and meshes with the corresponding two racks. The cylinder body is connected to one of the clamping plates, and the piston rod end of the cylinder is connected to the other clamping plate.

[0009] Preferably, the two sides of the movable frame are respectively rotatably connected to guide wheels that are rolledly connected to the guide rails on the support frame.

[0010] Preferably, there are two tension sprockets symmetrically arranged on the upper and lower sides of the movable frame.

[0011] Preferably, the inner side of the clamping plate is provided with an "X"-shaped rubber pad.

[0012] Preferably, the rubber pad has a plurality of anti-slip grooves evenly distributed on it.

[0013] Preferably, the rack and the mounting bracket are slidably connected.

[0014] The beneficial effects achieved by this invention are as follows: This application uses a translation mechanism and a lifting mechanism to drive the gripping mechanism to adjust its position. The gripping mechanism adopts a cylinder-driven structure with a rack and pinion and a moving gear linkage. When the cylinder is activated, the meshing transmission between the rack and the moving gear drives the two clamping plates to move synchronously in opposite directions or in opposite directions, ensuring the synchronicity of the clamping action and avoiding clamping deviation. The inner side of the clamping plate is equipped with an "X"-shaped rubber pad and evenly distributed anti-slip grooves. The "X"-shaped structure can increase the contact area with the surface of the express delivery, adapting to express delivery of different shapes and sizes. The anti-slip grooves can significantly improve the friction of the contact surface, effectively preventing the express delivery from slipping during clamping and transfer, and improving the reliability of clamping.

[0024] like Figure 1-6 As shown, the present invention provides a gripping device for logistics express delivery, including a support frame 1, a translation mechanism 3, a lifting mechanism 4 and a gripping mechanism 5; Furthermore, the translation mechanism 3 is mounted on the support frame 1 and is used to drive the movable frame 2 on it to move. The translation mechanism 3 includes a motor 35 and a chain 36. The two sides of one end of the support frame 1 are rotatably connected to the sprocket 32 ​​via a rotating shaft 31. The two sides of the other end of the support frame 1 are rotatably connected to the sprocket 34 via a rotating shaft 33. The motor 35 is mounted on the support frame 1 and its output shaft is connected to the rotating shaft 33. The sprocket 32 ​​and sprocket 34 on the same side are connected by the chain 36. However, the two sides of the movable frame 2 are respectively connected to the corresponding chain 36, and the two sides of the movable frame 2 are respectively rotatably connected to the guide wheel 37 that is rollingly connected to the guide rail on the support frame 1, so as to realize the smooth horizontal movement of the clamped express. In addition, the lifting mechanism 4 is mounted on the movable frame 2 and drives the gripping mechanism 5 on it to move up and down. The lifting mechanism 4 includes a lifting frame 41, a second chain 42, a second motor 43, a third sprocket 431, and a tension sprocket 44. The lifting frame 41 is slidably connected to the movable frame 2. The two ends of the second chain 42 are respectively connected to the upper and lower ends of the lifting frame 41. The second motor 43 is mounted on the movable frame 2 and its output shaft is equipped with a third sprocket 431 that meshes with the second chain 42. The tension sprocket 44 is rotatably connected to the movable frame 2 and meshes with the second chain 42. There are two tension sprockets 44, which are symmetrically arranged on the upper and lower sides of the movable frame 2, so that the express delivery on the lifting frame 41 can move up and down smoothly. In addition, the gripping mechanism 5 includes a gear disk 51, a motor 52, a clamping plate 55, a rack 57, a moving gear 58, and a cylinder 59. The gear disk 51 is rotatably connected to the lower end of the lifting frame 41. The motor 52 is mounted on the lifting frame 41, and a drive gear 521 that meshes with the gear disk 51 is mounted on its output shaft. A mounting frame 53 is provided below the gear disk 51. Two guide rods 54 are provided in parallel at the top and bottom sides of the mounting frame 53 in a cross shape. The two guide rods 54 on the same horizontal plane are slidably connected to the two ends of the clamping plate 55. A rack 57 is provided on the two clamping plates 55 on the same guide rod 54. The rack 57 is slidably connected to the mounting frame 53. The moving gear 58 is rotatably connected to the mounting frame 53 and meshes with the corresponding two racks 57. In addition, the cylinder body of the cylinder 59 is connected to one of the clamping plates 55, and the piston rod end of the cylinder 59 is connected to another clamping plate 55. The inner side of the clamping plate 55 is provided with an "X" shaped rubber pad 56. The rubber pad 56 is evenly distributed with several anti-slip grooves 561, which can effectively prevent it from rotating or slipping, thus improving the reliability of clamping. A clamping plate 55 is pushed by a cylinder 59, and under the linkage of a rack 57 and a moving gear 58, the clamping plate 55 is driven to move synchronously towards or away from each other. Detailed implementation methods and principles: When working, motor 1 35 starts first, and its output shaft drives the connected rotating shaft 2 33 to rotate. The rotating shaft 2 33 drives the sprockets 2 34 at both ends to rotate synchronously. Therefore, when the sprockets 2 34 rotate, they will drive the moving frame 2 to move along the length of the support frame 1 through the chain 1 36. At the same time, the guide wheels 37 on both sides of the moving frame 2 roll along the guide rail on the support frame 1 and accurately move to the target express delivery position. Then, motor 2 43 starts, and its output shaft drives sprocket 3 431 to rotate. Sprocket 3 431 meshes with chain 2 42 for transmission. Since the two ends of chain 2 42 are fixedly connected to the upper and lower ends of the lifting frame 41 respectively, when sprocket 3 431 rotates, it drives the lifting frame 41 to slide up and down along the moving frame 2 through chain 2 42, realizing the lifting adjustment of the gripping mechanism 5 until the clamping plate 55 of the gripping mechanism 5 drops to the corresponding height on both sides of the express to be gripped, and the lifting mechanism 4 stops operating. After the gripping mechanism 5 is in position, the motor 3 52 starts, and the output shaft drives the drive gear 521 to rotate. The drive gear 521 drives the gear disk 51 and the mounting bracket 53 below to rotate until the clamping plate 55 is aligned with the express clamping requirements. Then the cylinder 59 starts. When the piston rod of the cylinder 59 extends or retracts, it drives one of the clamping plates 55 to slide along the guide rod 54. Since both clamping plates 55 on the same guide rod 54 are equipped with racks 57, and the moving gear 58 rotatably connected to the mounting bracket 53 meshes with the two racks 57 at the same time, when one clamping plate 55 moves, it drives the moving gear 58 to rotate through the rack 57, thereby driving the other rack 57 and the corresponding clamping plate 55 to slide synchronously in the opposite direction, realizing the opposite movement of the two clamping plates 55. During the clamping process, the rubber pad 56 on the inner side of the clamping plate 55 contacts the surface of the express delivery. The anti-slip grooves 561 evenly distributed on the rubber pad 56 can increase the friction between the express delivery and the express delivery, preventing the express delivery from slipping.

[0025] After the package is securely clamped, the lifting mechanism 4 starts first, and the second motor 43 rotates in reverse. Through the third sprocket 431 and the second chain 42, the lifting frame 41 and the gripping mechanism 5 holding the package are raised until the package is removed from the initial placement surface and reaches a safe transfer height to avoid interference with other objects during the transfer process. Then the translation mechanism 3 starts again, and the first motor 35 rotates in reverse or forward, driving the moving frame 2 and the package to move horizontally along the support frame 1 to directly above the preset placement position. Once the device is moved to the placement position, the lifting mechanism 4 is activated, and the motor 43 rotates in the forward direction, driving the lifting frame 41 to slowly lower the gripping mechanism 5 and the express delivery until the express delivery is placed at the target position. Subsequently, the cylinder 59 moves in the reverse direction, and the piston rod drives the clamping plate 55 to move in the reverse direction. Through the transmission action of the rack 57 and the moving gear 58, the two clamping plates 55 move away from each other, releasing the clamp on the express delivery. Finally, the lifting mechanism 4 drives the gripping mechanism 5 to rise to a safe height, completing the placement of the express delivery.
