Description

Technical Field

[0001] The present invention relates to the field of logistics palletizing, and in particular to a logistics palletizer for transporting logistics packages and a use method thereof. Background Art

[0002] The palletizer places the packaged materials on pallets and stacks in a certain arrangement, and automatically stacks them. It can stack multiple layers and then push them out to facilitate forklift transportation to the warehouse for storage. When the palletizer stacks multiple layers of logistics packages, staff are required to use forklifts to transport them.

[0003] The existing patent (publication number: CN111747127B) discloses a logistics palletizer for transporting logistics packages, including a clamping and placing mechanism and a receiving and stacking mechanism. The receiving and stacking mechanism is arranged on the left side of the clamping and placing mechanism. The clamping and placing mechanism clamps the cloth roll and places the items in the material discharging basket in turn. When placing the items, it drives the receiving and stacking mechanism to push out three material discharging baskets in turn to stack them in layers, so that the cylindrical cloth roll can be clamped and placed in the material discharging bin, so that the cylindrical cloth roll will not roll over when stacked, and the stacking is more stable. No human participation is required, and the stacking is fully automatic, which is convenient and fast. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: the existing palletizing mechanism needs to clamp the package when transporting the package, and the package is clamped by a clamping plate. If the clamping force is too small during the clamping process, the package will fall from between the two clamping plates, causing damage to the transported items in the package. If the clamping force of the two clamping plates on the package is too large, the package will be deformed, causing the package to fall from between the two clamping plates after deformation.

[0009] Preferably, the two pushing devices each include a rotating sleeve which is rotatably arranged at the bottom of the clamping plate, the bottom of the clamping plate is located between the two rotating sleeves and two positioning rods are slidably arranged, a positioning plate is fixedly connected between the two positioning rods, a tension spring is arranged between the positioning plate and the bottom of the clamping plate, a one-way shaft is fixedly connected at the axis center of the two rotating sleeves, a transmission gear is fixedly connected to the one-way shaft, and the transmission gear is meshed with the teeth of the sliding frame on the side away from the rotating gear.

[0010] Preferably, a movable groove is provided on the outer wall of the rotating sleeve, and the movable groove includes an arc groove and a vertical groove. The two positioning rods are respectively provided with abutment wheels extending toward the movable grooves in the two rotating cylinders, and the bottoms of the two positioning rods are fixedly connected with a pressure plate.

[0011] Preferably, the method for using the logistics palletizer for transporting logistics packages comprises the following steps: S1: When stacking logistics packages, the load-bearing bracket is driven to move above the package through the mechanical wall of the peripheral device, and the rotating frame is rotated under the drive of the driving motor. When the rotating frame rotates, the rotating frame can synchronously pull the connecting rod to move, and then synchronously drive the two clamping devices to move relatively toward the package. When the connecting rod drives the mobile frame to move toward the outer wall of the package, the set clamping plate will contact the outer wall of the package. The mobile frame continues to move and drives the support frame to move toward the package. After the clamping plate contacts the outer wall of the package, the support frame continues to move. The support frame squeezes the connecting spring to cause the support frame and the clamping plate to move relative to each other, thereby applying pressure to the outer wall of the package, so that the package can be stably clamped under the clamping force of the two clamping plates. S2: After the clamping plate clamps the outer wall of the package, the support frame continues to move so that the support frame and the clamping plate move relative to each other, and the sliding frame on the support frame moves toward the direction of the clamping plate. At this time, the teeth on the sliding frame will contact the rotating gear, thereby driving the rotating gear to rotate. When the rotating gear rotates, it will drive the rotating rod to rotate. The rotation of the rotating rod drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate. At this time, the first bevel gear drives the rotating rod to rotate, and the swing frame set on the rotating rod will deflect toward the direction of the package on the fixed frame. During the movement of the swing frame, due to the limited opening on the swing frame, The cam is moved in a direction such that the roller is restrained in the slide groove on the fixed frame, and the roller is driven to move along the slide groove. At this time, the cam moves in the direction of the package, and the roller arranged on the cam moves to the bottom of the package, so that the roller moves to the bottom of the package to support the bottom of the package. The longitudinal limit frame and the transverse limit plate are arranged to limit and stabilize the movement of the limit rod during the movement of the limit rod, and the roller moves to the bottom of the package, so that after the package is clamped, the bottom of the package can be stabilized by the roller support. S3: After the clamping device cooperates with the supporting device to clamp the package, when the package moves to the top of the stacking rack to stack the package, the driving motor drives the rotating rack to rotate and reset. At this time, the moving rack will drive the fixed rod to move the support rack in the direction away from the package, thereby causing the support rack to gradually move and reset. At this time, when the support rack and the clamping plate move relative to each other, the rotating gear will rotate under the drive of the teeth on the sliding rack, and then the supporting device will be moved away from the bottom of the package under the drive of the rotating gear. While the sliding rack moves, the teeth on the other side of the sliding rack will drive the transmission gear on the one-way shaft to rotate. The rotation of the transmission gear drives the one-way shaft to rotate at this time, and the one-way shaft rotates to rotate the rotating sleeve. When the rotating sleeve rotates, the resistance wheel that contacts the rotating sleeve will drive the positioning rod downward under the drive of the arc groove. The downward movement of the two positioning rods will drive the pressure plate to press toward the top of the package, so that when the package is stacked, the pressure plate presses toward the top of the package, so that the gap between the stacked packages is reduced, which is convenient for the subsequent handling of the packages after stacking.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, after the clamping plate contacts the outer wall of the package, when the support frame continues to move, the support frame squeezes the connecting spring to cause relative movement between the support frame and the clamping plate, thereby applying pressure to the outer wall of the package, so that the package can be stably clamped under the clamping force of the two clamping plates.

[0013] In the present invention, the roller moves to the bottom of the package to support the bottom of the package. The longitudinal limit frame and the transverse limit plate are provided to limit and stabilize the movement of the limit rod during the movement. The roller moves to the bottom of the package, so that after the package is clamped, the bottom of the package can be stabilized by the roller support. The package is clamped by the clamping plate. During the clamping process, if the clamping force is too small, the package will fall from between the two clamping plates, causing damage to the transported items in the package. If the clamping force of the two clamping plates on the package is too large, the package will be deformed, causing the package to fall from between the two clamping plates after deformation. Then, the package is first clamped and limited by the clamping plate. After the clamping limit, the bottom of the package is supported by the controlled supporting device, thereby achieving a stabilizing effect on the package during stacking and conveying.

[0014] In the present invention, when the one-way shaft rotates, the rotating sleeve rotates. When the rotating sleeve rotates, the interference wheel that interferes in the rotating sleeve will drive the positioning rod to move downward under the drive of the arc groove. The downward movement of the two positioning rods will drive the pressure plate to press upward on the package, so that when the package is stacked, the pressure plate presses upward on the package, which reduces the gap between the stacked packages and facilitates the subsequent handling of the packages after palletizing.

When the rotating frame 12 rotates, the rotating frame 12 can synchronously pull the connecting rod 22 to move, and then synchronously drive the two clamping devices 2 to move relative to the package. When the connecting rod 22 drives the mobile frame 21 to move toward the outer wall of the package, the set clamping plate 25 will contact the outer wall of the package, and the mobile frame 21 continues to move to drive the support frame 24 to move toward the package. After the clamping plate 25 contacts the outer wall of the package, the support frame 24 continues to move, and the support frame 24 squeezes the connecting spring 27 to cause the support frame 24 and the clamping plate 25 to move relative to each other, thereby applying pressure to the outer wall of the package, which can enable the package to be stably clamped under the clamping force of the two clamping plates 25.

A rotating rod 33 is rotatably provided on the fixed frame 31, and a first bevel gear 34 is fixedly connected to the rotating rod 33. The end of the rotating rod 28 away from the rotating gear 29 is fixedly connected to the second bevel gear 35, and the first bevel gear 34 is meshed with the second bevel gear 35. The end of the rotating rod 33 away from the first bevel gear 34 is fixedly connected to a swing frame 36, and a limiter 4 for limiting the swing frame 36 is also provided on the fixed frame 31; The limiting member 4 includes a transverse limiting plate 41 slidably arranged on the fixed frame 31, a longitudinal limiting frame 42 is longitudinally slidably arranged on the transverse limiting plate 41, a limiting groove 37 is provided on the swing frame 36, a roller 43 is inserted between the limiting groove 37 and the slide groove 32 on the fixed frame 31, a limiting rod 44 is rotatably connected to the roller 43, and a roller 45 is also fixedly connected to the limiting rod 44, the limiting rod 44 is extended toward the direction of the fixed frame 31, and the limiting rod 44 is rotatably matched with the longitudinal limiting frame 42; After the clamping plate 25 clamps the outer wall of the package, the support frame 24 continues to move so that the support frame 24 and the clamping plate 25 move relative to each other, and the sliding frame 210 on the support frame 24 moves toward the clamping plate 25. At this time, the teeth 211 on the sliding frame 210 contact the rotating gear 29, thereby driving the rotating gear 29 to rotate. When the rotating gear 29 rotates, it drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives the second bevel gear 35 to rotate, and the second bevel gear 35 drives the first bevel gear 35 to rotate. The gear 34 rotates, and the first bevel gear 34 drives the rotating rod 33 to rotate. The swing frame 36 provided on the rotating rod 33 deflects on the fixed frame 31 in the direction of the package. During the movement of the swing frame 36, the limiting groove 37 is provided on the swing frame 36, so that when the swing frame 36 rotates, the limiting groove 37 on the swing frame 36 can drive the roller 43 to move, and the roller 43 is limited in the slide groove 32 on the fixed frame 31, so that the roller 43 can drive the limiting rod 44 along the direction of the slide groove 32. The limit rod 44 moves in the direction of the package, and the roller 45 provided on the limit rod 44 moves to the bottom of the package, so that the roller 45 moves to the bottom of the package to support the bottom of the package. The longitudinal limit frame 42 and the transverse limit plate 41 set to limit the limit rod 44 during the movement of the limit rod 44 to stabilize the movement of the limit rod 44, and the roller 45 moves to the bottom of the package, so that after the package is clamped, the bottom of the package can be supported and stabilized by the roller 45, and the package is clamped by the clamping plate 25. If the clamping force of the two clamping plates 25 is too small during the clamping process, the package will fall from between the two clamping plates 25, causing damage to the transported items in the package. If the clamping force of the two clamping plates 25 on the package is too large, the package will be deformed, causing the package to fall from between the two clamping plates 25 after deformation. The clamping plates 25 are used to clamp and limit the package first. After the clamping is limited, the supporting device 3 is controlled to support the bottom of the package, thereby achieving a stable effect during the package stacking and transportation process.

[0021] In this embodiment, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the two pushing devices 5 each include a rotating sleeve 51 which is correspondingly rotatably arranged at the bottom of the clamping plate 25, the bottom of the clamping plate 25 is located between the two rotating sleeves 51 and two positioning rods 52 are slidably arranged, a positioning plate 53 is fixedly connected between the two positioning rods 52, a tension spring 54 is arranged between the positioning plate 53 and the bottom of the clamping plate 25, a one-way shaft 55 is fixedly connected at the axis of the two rotating sleeves 51, a transmission gear 56 is fixedly connected to the one-way shaft 55, and the transmission gear 56 is meshed with the teeth 211 of the sliding frame 210 away from the rotating gear 29; The outer wall of the rotating sleeve 51 is provided with a moving groove 57, and the moving groove 57 includes an arc groove 58 and a vertical groove 59. The two positioning rods 52 are respectively provided with abutment wheels 510 extending toward the moving grooves 57 in the two rotating cylinders, and the bottoms of the two positioning rods 52 are fixedly connected with a pressing plate 511. After the clamping device 2 cooperates with the supporting device 3 to clamp the package, when the package moves to the top of the stacking rack to stack the package, the driving motor 11 drives the rotating rack 12 to rotate and reset. At this time, the moving rack 21 drives the fixing rod 23 to move the supporting rack 24 in the direction away from the package, thereby causing the supporting rack 24 to gradually move and reset. At this time, when the supporting rack 24 and the clamping plate 25 move relative to each other, the rotating gear 29 is driven by the teeth 211 on the sliding rack 210 to rotate, and then the supporting device 3 is moved away from the bottom of the package under the drive of the rotating gear 29. While the sliding rack 210 moves, another gear on the sliding rack 210 is driven to rotate. The side teeth 211 will drive the transmission gear 56 on the one-way shaft 55 to rotate. The rotation of the transmission gear 56 will drive the one-way shaft 55 to rotate. When the one-way shaft 55 rotates, the rotating sleeve 51 will rotate. When the rotating sleeve 51 rotates, the interference wheel 510 in the rotating sleeve 51 will drive the positioning rod 52 to move downward under the drive of the arc groove 58. The downward movement of the two positioning rods 52 will drive the pressure plate 511 to press upward on the package, so that when the package is stacked, the pressure plate 511 will press upward on the package, so that the gap between the stacked packages is reduced, which is convenient for the subsequent handling of the packages after palletizing.

[0022] The use method and advantages of the present invention: The use method of the logistics palletizer for transporting logistics packages, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown: S1: When stacking logistics packages, the load-bearing bracket 1 is driven to move to the top of the package through the mechanical wall of the external device, and the rotating frame 12 is rotated under the drive of the driving motor 11. When the rotating frame 12 rotates, the rotating frame 12 can synchronously pull the connecting rod 22 to move, and then synchronously drive the two clamping devices 2 to move relatively toward the package. When the connecting rod 22 drives the mobile frame 21 to move toward the outer wall of the package, the set clamping plate 25 will contact the outer wall of the package, and the mobile frame 21 continues to move to drive the support frame 24 to move toward the package. After the clamping plate 25 contacts the outer wall of the package, when the support frame 24 continues to move, the support frame 24 squeezes the connecting spring 27 to cause the support frame 24 and the clamping plate 25 to move relative to each other, thereby applying pressure to the outer wall of the package, so that the package can be stably clamped under the clamping force of the two clamping plates 25; S2: After the clamping plate 25 clamps the outer wall of the package, the support frame 24 continues to move so that the support frame 24 and the clamping plate 25 move relative to each other, and the sliding frame 210 on the support frame 24 moves toward the direction of the clamping plate 25. At this time, the teeth 211 on the sliding frame 210 will contact the rotating gear 29, thereby driving the rotating gear 29 to rotate. When the rotating gear 29 rotates, it will drive the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives the second bevel gear 35 to rotate, and the second bevel gear 35 drives the first bevel gear 34 to rotate. At this time, the first bevel gear 34 drives the rotating rod 33 to rotate, and the swing frame 36 set on the rotating rod 33 will deflect toward the direction of the package on the fixed frame 31. During the movement of the swing frame 36, due to the swing frame 36 A limiting groove 37 is provided on the upper surface, so that when the swing frame 36 rotates, the limiting groove 37 on the swing frame 36 can drive the roller 43 to move, and the roller 43 is limited in the slide groove 32 on the fixed frame 31, so that the roller 43 can drive the limiting rod 44 to move along the direction of the slide groove 32. At this time, the limiting rod 44 moves in the direction of the package, and the roller 45 provided on the limiting rod 44 will move to the bottom of the package, so that the roller 45 moves to the bottom of the package to support the bottom of the package. The longitudinal limiting frame 42 and the transverse limiting plate 41 are provided to limit and stabilize the movement of the limiting rod 44 during the movement of the limiting rod 44, and the roller 45 moves to the bottom of the package, so that after the package is clamped, the bottom of the package can be supported and stabilized by the roller 45; S3: After the clamping device 2 cooperates with the supporting device 3 to clamp the package, when the package moves to the top of the stacking rack to stack the package, the driving motor 11 drives the rotating rack 12 to rotate and reset. At this time, the moving rack 21 drives the fixing rod 23 to move the supporting rack 24 in the direction away from the package, so that the supporting rack 24 gradually moves and resets. At this time, when the supporting rack 24 and the clamping plate 25 move relative to each other, the rotating gear 29 is rotated under the drive of the teeth 211 on the sliding rack 210, and the supporting device 3 is moved away from the bottom of the package under the drive of the rotating gear 29. While the sliding rack 210 moves, the gear 211 on the sliding rack 210 is rotated. The teeth 211 on the other side will drive the transmission gear 56 on the one-way shaft 55 to rotate. The rotation of the transmission gear 56 will drive the one-way shaft 55 to rotate. When the one-way shaft 55 rotates, the rotating sleeve 51 will rotate. When the rotating sleeve 51 rotates, the interference wheel 510 that interferes with the rotating sleeve 51 will drive the positioning rod 52 to move downward under the drive of the arc groove 58. The downward movement of the two positioning rods 52 will drive the pressure plate 511 to press upward on the package. As a result, when the package is stacked, the pressure plate 511 presses upward on the package, so that the gap between the stacked packages is reduced, which is convenient for the subsequent handling of the packages after stacking.

8. A method for using a logistics palletizer for transporting logistics packages, using the logistics palletizer for transporting logistics packages as described in any one of claims 1 to 7, characterized in that: The steps include: S1: When stacking logistics packages, the load-bearing bracket (1) is driven to move above the package through the mechanical wall of the external device, and the rotating frame (12) is rotated under the drive of the driving motor (11). When the rotating frame (12) rotates, the rotating frame (12) can synchronously pull the connecting rod (22) to move, thereby synchronously driving the two clamping devices (2) to move relative to the package. When the connecting rod (22) drives the moving frame (21) to move toward the outer wall of the package, the set clamping plate (25) will contact the outer wall of the package, and the moving frame (21) continues to move to drive the support frame (24) to move toward the package. After the clamping plate (25) contacts the outer wall of the package, when the support frame (24) continues to move, the support frame (24) squeezes the connecting spring (27) to cause the support frame (24) and the clamping plate (25) to move relative to each other, thereby applying pressure to the outer wall of the package, so that the package can be stably clamped under the clamping force of the two clamping plates (25); S2: After the clamping plate (25) clamps the outer wall of the package, the support frame (24) continues to move so that the support frame (24) and the clamping plate (25) move relative to each other, and the sliding frame (210) on the support frame (24) moves toward the clamping plate (25). At this time, the teeth (211) on the sliding frame (210) contact the rotating gear (29), thereby driving the rotating gear (29) to rotate. When the rotating gear (29) rotates, it drives the rotating rod (28) to rotate. The rotation of the rotating rod (28) drives the second bevel gear (35) to rotate. The second bevel gear (35) drives the first bevel gear (34) to rotate. At this time, the first bevel gear (34) drives the rotating rod (33) to rotate. The swing frame (36) provided on the rotating rod (33) deflects toward the direction of the package on the fixed frame (31). During the movement of the swing frame (36), due to the swing frame ( A limiting groove (37) is provided on the swing frame (36), so that when the swing frame (36) rotates, the limiting groove (37) on the swing frame (36) can drive the roller (43) to move, and the roller (43) is limited in the slide groove (32) on the fixed frame (31), so that the roller (43) can drive the limiting rod (44) to move along the direction of the slide groove (32), at this time, the limiting rod (44) moves in the direction of the package, and the roller (45) provided on the limiting rod (44) will move to the bottom of the package, so that the roller (45) moves to the bottom of the package to support the bottom of the package, and the longitudinal limiting frame (42) and the transverse limiting plate (41) are provided so that the limiting rod (44) limits and stabilizes the movement of the limiting rod (44) during the movement, and the roller (45) moves to the bottom of the package, so that after the package is clamped, the bottom of the package can be supported and stabilized by the roller (45); S3: After the clamping device (2) cooperates with the supporting device (3) to clamp the package, when the package moves to the top of the stacking rack to stack the package, the driving motor (11) drives the rotating rack (12) to rotate and reset, and the moving rack (21) drives the fixing rod (23) to move the supporting rack (24) in a direction away from the package, thereby causing the supporting rack (24) to gradually move and reset. At this time, when the supporting rack (24) and the clamping plate (25) move relative to each other, the teeth (211) on the sliding rack (210) drive the rotating gear (29) to rotate, and then the supporting device (3) is moved away from the bottom of the package under the drive of the rotating gear (29). While the sliding rack (210) moves, the sliding rack (210) The teeth (211) on the other side of the upper portion drive the transmission gear (56) on the one-way shaft (55) to rotate. The rotation of the transmission gear (56) drives the one-way shaft (55) to rotate. When the one-way shaft (55) rotates, the rotating sleeve (51) rotates. When the rotating sleeve (51) rotates, the interference wheel (510) in the rotating sleeve (51) drives the positioning rod (52) to move downward under the drive of the arc groove (58). The downward movement of the two positioning rods (52) drives the pressing plate (511) to press upward on the package. When the package is stacked, the pressing plate (511) presses upward on the package, thereby reducing the gap between the stacked packages and facilitating the subsequent handling of the package after stacking.
