Description

Technical Field

[0001] The utility model relates to the technical field of packaging box palletizing equipment, in particular to a packaging box palletizing machine. Background Art

[0002] Nowadays, most products cannot be separated from the packaging of cartons. After the products are packed in cartons, in order to facilitate storage or subsequent logistics transportation, the cartons usually need to be stacked, that is, stacked neatly and placed side by side.

[0003] Most existing packaging boxes are still stacked by manual handling and stacking, which is labor-intensive and inefficient, and the stacking height of the packaging boxes is low, and there are risks of box tipping and safety hazards. In order to achieve fast and efficient stacking of packaging boxes, the present application provides a packaging box stacker. Utility Model Content

[0004] The utility model aims to provide a packing box palletizer, which has a simple and reasonable design and a stable and reliable structure; can quickly and efficiently stack the packing boxes delivered in, so that the packing boxes are neatly stacked in piles; improves work efficiency and reduces labor costs.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A palletizer for packaging boxes, comprising a box input component, a palletizing mechanism, and a box output component;

[0007] The box input assembly, the stacking mechanism, and the box output assembly are sequentially arranged side by side in a straight line;

[0008] The stacking mechanism includes a box lifting assembly, a box supporting assembly, a conveying assembly, and a frame; the box lifting assembly includes a box lifting cylinder, a box lifting frame, a guide shaft, a lifting seat, and a linear bearing. The box lifting cylinder is vertically fixed on the frame, and its output shaft is connected to the horizontal lifting seat, and a horizontal box lifting frame is fixed on the top of the lifting seat. The frame is also provided with two guide shafts, which are arranged on both sides of the lifting seat; the two ends of the lifting seat are sleeved on the guide shafts through linear bearings. The box lifting frame is used to hold up the packaging box, and its four side edges are provided with limit claws.

[0009] The conveying assembly is provided with a clearance cavity, and the lifting box is mounted in the clearance cavity and can be lifted up and down in the clearance cavity.

[0010] The box input assembly, box output assembly, and conveying assembly are all material conveying lines, which are all existing technologies and will not be described here. They can be composed of a motor, a conveyor belt, a driving shaft, and a driven shaft, or they can be composed of a motor, several rollers, gears, and a transmission chain.

[0011] There are two box-carrying assemblies, which are arranged above the conveying assembly at intervals relative to each other;

[0012] The box support assembly includes a mounting seat, a guide rail, a slider, a push-up cylinder, and a support plate; the mounting seat is horizontally fixed on the frame, and a horizontally arranged guide rail is arranged on it, and a slider is sleeved on the guide rail. The push-up cylinder is horizontally fixed on the mounting seat, and its output shaft is connected to the rear end of the horizontally arranged support plate; the bottom end of the support plate is fixed on the slider. The front end of the support plate is provided with a claw for inserting into the gap at the bottom of the packaging box and lifting the packaging box (usually, the bottom of the packaging box will have a gap or slot for forklift insertion). The palletizer of the present application is specifically used for the palletizing of packaging boxes with slots at the bottom or top.

[0013] Briefly describe its working principle: the packaging box is transported in from the box input assembly, and when it enters the conveying assembly, the box lifting assembly lifts the packaging box to a certain height, while leaving space for a packaging box at the bottom;

[0014] At the same time, the support plate of the box support assembly is pushed by the push cylinder, so that the claws on the support plate extend into the bottom of the packaging box to hold up the packaging box;

[0015] Then the box lifting assembly descends and falls under the conveying assembly. When the next packaging box is conveyed to the conveying assembly again, the box lifting assembly rises and holds up the packaging box. When the packaging box touches the bottom surface of the upper packaging box, the box supporting assembly pulls out the claws and returns to its position, allowing the packaging box to continue to rise. When the lower packaging box rises to a certain height, the claws of the box supporting assembly rise to the bottom of the lowest packaging box to hold the packaging box.

[0016] For example, packaging boxes A, B, C, and D are conveyed in sequence, the box lifting assembly pushes packaging boxes A, B, C, and D to the clamping and supporting position of the box supporting assembly in sequence, and the claws are inserted into the bottom of packaging boxes A, B, C, and D in sequence; packaging boxes A, B, C, and D are stacked and palletized from top to bottom in sequence.

[0017] If a stack needs to be stacked with 4 cartons, when the fourth carton is transported to the conveying assembly, the box lifting assembly still pushes the top box up until its top surface contacts the bottom surface of the upper box, and then the box supporting assembly pulls out the claws and returns to its position. At the same time, the box lifting assembly falls back, so that the bottom surfaces of the 4 stacked cartons contact the conveying assembly, and the conveying assembly transports the 4 cartons to the box output assembly.

[0018] Beneficial effects of the utility model:

[0019] The design is simple and reasonable, the structure is stable and reliable; it can quickly and efficiently stack the incoming packaging boxes, so that the packaging boxes are neatly stacked; it improves work efficiency and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
