Description

Technical Field

[0001] The present application relates to the technical field of corrugated cardboard production, and in particular to a double-line palletizer. Background Art

[0002] Corrugated cardboard is a widely used packaging cardboard. Existing corrugated cardboard is generally made into continuous sheets of corrugated cardboard, and then cut and pressed according to the required size, and finally made into corrugated cardboard of predetermined specifications.

Later, the bundled stacks are stacked on pallets, thereby saving storage space and improving transportation efficiency. At present, there are usually two stacking methods for stacking multiple stacks of corrugated cardboard on pallets. The first is to transport them from the line to the operating station and stack them manually. The second is to transport them from the line to the operating station and have a robot grab them one by one and stack them on the pallet. However, the stacking efficiency of the corrugated cardboard stacks in these two stacking methods is low.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present application.

[0026] Example

[0027] In order to solve the defects of the existing technology of using manual stacking or using a single robot to stack paper into a pallet, Figure 1-Figure 3 As shown, the present application discloses a double-line palletizer, comprising a first roller line 10, a second roller line 20, a third roller line 30 and a paper stack handling mechanism 40;

[0028] The first roller line 10 and the second roller line 20 are both arranged along a first direction for conveying paper stacks;

[0029] The third roller line 30 is arranged along the second direction for conveying the stacked pallets; the first direction and the second direction are perpendicular to each other;

[0030] The paper stack handling mechanism 40 includes two longitudinal moving components 41 arranged outside the first roller line 10 and the second roller line 20 along the first direction, a truss 42 connected above the two longitudinal moving components 41, two lateral moving components 43 arranged above the truss 42, two lifting moving components 44 respectively arranged on the two lateral moving components 43, and two stacking and handling robots 45 respectively arranged on the two lifting moving components 44.

[0031] Based on the above structure, in a specific implementation, at least two pallets are placed at the conveying starting end of the third roller line 30 and are respectively conveyed to the set position by the third roller line 30. After that, the bundled paper stack is conveyed forward by the first roller line 10 and the second roller line 20. When the paper stack is conveyed to the conveying end of the first roller line 10 and the second roller line 20, it stops. In this process, the two longitudinal moving components 41 drive the truss 42 to the top of the first roller line 10 and the second roller line 20, and the two lateral moving components 43 drive the two lifting moving components 44 and The paper stacks on the first roller line 10 and the second roller line 20 are facing each other, and the two lifting and moving components 44 drive the two stacking and handling robots 45 to descend and clamp the paper stacks on the first roller line 10 and the second roller line 20. After that, the two longitudinal moving components 41 drive the truss 42 to the top of the third roller line 30, and the two transverse moving components 43 drive the two lifting and moving components 44 to be opposite to the two pallets on the third roller line 30. The two lifting and moving components 44 drive the two stacking and handling robots 45 to descend and place the clamped paper stacks onto the two pallets for stacking.

[0032] In addition to the above structure, the present application also provides a first baffle 50 at the conveying end of the first roller line 10 and the second roller line 20 respectively, and a counting camera 60 is provided on the side of the first baffle 50 facing away from the third roller line 30. When the first roller line 10 and the second roller line 20 carry the paper stack to the end, the paper stack will be blocked by the first baffle 50, and in order to ensure that the two stacking and handling robots 45 can stack a set number of paper stacks on each pallet, each counting camera 60 will count after the two stacking and handling robots 45 transport a paper stack each time.

[0033] Similarly, the present application also includes two blocking assemblies 70 respectively arranged below the gap between the two rollers of the third roller line 30. The blocking assembly 70 includes two cylinders 71 and two second baffles 72. The two baffles are respectively connected to the piston rods of the two cylinders 71. Driven by the two cylinders 71, the two second baffles 72 can respectively pass through the two roller gaps of the third roller line 30. When the third roller line 30 transports two pallets, when the first pallet passes through the first blocking assembly 70, the pallet is not blocked, and the second blocking assembly 70 will be activated to block it. When the second pallet passes through the first blocking assembly 70, the first blocking assembly 70 will block the pallet. Specifically, the blocking function is achieved by the cylinder 71 driving the second baffle 72 to pass through the roller gap of the third roller line 30.

[0034] As a preferred embodiment of the present application, the longitudinal moving component 41 is a servo ball screw module. During the specific implementation process, if there are other types of longitudinal moving components 41 that can replace the servo ball screw module to achieve the corresponding functions, personnel in this technical field can adaptably select them.

[0035] In one embodiment, the lateral movement assembly 43 of the present application includes two guide rails 431 arranged side by side above the truss 42, a rack 432 arranged on the lateral arm between the two guide rails 431, a lateral movement seat 433 slidingly arranged on the two guide rails 431, a reduction motor 434 arranged on the lateral movement seat 433 and having its output shaft passing through the lateral movement seat 433, and a gear 435 installed on the output shaft of the reduction motor 434 and meshing with the rack 432. When the reduction motor 434 drives the gear 435 to rotate, the gear 435 cooperates with the rack 432 to enable the lateral movement seat 433 to move laterally.

[0036] In one embodiment, the lifting and moving component 44 of the present application includes a vertical plate 441 vertically arranged on one side of the horizontal moving seat 433, a hydraulic slide 442 arranged on the vertical plate 441 and a lifting arm 443 arranged on the hydraulic slide 442. Driven by the hydraulic slide 442, the lifting arm 443 of the present application can be lifted and lowered. Correspondingly, the stacking and handling robot 45 arranged on the lifting and moving component 44 rises and falls with the lifting and lowering of the lifting arm 443.

[0037] In one embodiment, the palletizing and handling robot 45 includes a connecting plate 451 provided at the bottom of the lifting arm 443, a double-slide screw module 452 provided at the bottom of the connecting plate 451, and clamps 453 respectively connected to the two slides of the double-slide screw module 452. When clamping the paper stack, the double-slide screw module 452 drives the two clamps 453 to move toward each other. When lowering the paper stack, the slide screw module drives the two clamps 453 to move away from each other.
