Description

A cardboard box palletizer Technical Field

[0001] This utility model relates to the field of palletizing machine technology, and in particular to a carton palletizing machine. Background Technology

[0002] Currently, the palletizing operations in my country use two methods: manual handling and mechanical palletizing machines. Manual handling suffers from high labor intensity, low efficiency, and poor safety.

[0003] Mechanical palletizers automatically stack pre-packaged cartons on pallets, stacking them multiple layers high. Then, they are placed on pallets and transported to warehouses by forklifts.

[0004] Mechanical palletizers, however, are limited by structural factors and have disadvantages such as large footprint, complicated operation program changes, and high power consumption.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this utility model is to provide a carton palletizer that has a small footprint, is easy to operate, and has a wide range of applications.

[0007] This utility model provides a carton palletizing machine, including a frame, a lifting mechanism, a lifting frame, a translation panel, a reduction motor, a translation sprocket, a first support plate, a cylinder, a clamping plate, a second support plate, a rotating shaft, a connecting rod, a tilting cylinder, and a tilting baffle. The lifting mechanism is installed at the upper end of the frame and is connected to the lifting frame to drive the lifting frame to move up and down. The lifting frame is generally U-shaped, with chain guides on the inner walls of both sides. Connecting rods extending outward are provided on both sides of the translation panel, and the connecting rods are slidably inserted into the chain guides. The translation sprocket is rotatably connected to the front end of the inner walls of both sides of the lifting frame, and the reduction motor is fixedly connected to the other end of the lifting frame. The output end of the geared motor is connected to another translation sprocket, and the two translation sprockets are connected by a chain. The edge of the connecting rod is connected to the chain. The first support plate is vertically connected to the front end and the left and right side ends of the lifting frame. The cylinder is connected to the first support plate, and the output end of the cylinder is connected to the clamping plate. The second support plate is also vertically connected to the left and right side ends of the lifting frame. The rotating shaft is rotatably connected between the two second support plates, and the tilting baffle is fixedly connected to the rotating shaft. The connecting rod is fixedly connected to both ends of the rotating shaft. The other end of the connecting rod is hinged to the output end of the tilting cylinder, and the tilting cylinder is fixed to the lifting frame.

[0008] Using the above technical solution, when the geared motor rotates, it drives the chain to move, thereby driving the translation panel to move along the chain guide rail; when the cylinder extends or retracts, it drives the clamping plate to move back and forth; when the tilting cylinder extends or retracts, it drives the tilting baffle to rotate through the rotating shaft; when the carton palletizer is working, the entire layer of cartons is pushed from the carton sorting machine onto the translation panel. The translation panel is moved to a suitable position directly above the pallet by the lifting mechanism and the geared motor. The cylinder piston rod extends, and the tilting cylinder piston rod extends. At this time, the entire layer of cartons is held by the clamping plate and the tilting baffle on all four sides. Then, the geared motor drives the chain to pull out the translation panel and return it to the initial position. The cartons fall onto the pallet below. Then, all the cylinder piston rods retract, and this layer of palletizing is completed, and the next palletizing operation begins.

[0009] Furthermore, the frame includes a top frame and columns; the top frame is U-shaped, and the columns are vertically connected to the four sides of the bottom of the top frame; guide wheels are rotatably connected to the four sides of the lifting frame, and the guide wheels rotate to fit against the surface of the columns.

[0010] Furthermore, the lifting mechanism includes a reducer, a servo motor, bearing seats, a main shaft, lifting sprockets, and a drive sprocket; multiple bearing seats are vertically connected to both the front and rear edges of the top frame, the main shaft is installed in the bearing seats, and the lifting sprockets are fixedly connected to the middle and both ends of the main shaft; the reducer is fixedly connected to the middle of the top frame, and a servo motor for driving the reducer to rotate is installed on the reducer; the output end of the reducer is connected to the drive sprocket, and the drive sprocket is connected to the lifting sprocket located in the middle of the main shaft via a chain; the lifting sprockets located at both ends of the main shaft are connected to the lifting frame via chains.

[0011] This invention relates to a carton palletizing machine. When the geared motor rotates, it drives the chain to move, which in turn moves the translation panel along the chain guide. When the cylinder extends or retracts, it moves the clamping plate back and forth. When the tilting cylinder extends or retracts, it drives the tilting baffle to rotate via the rotating shaft. When the carton palletizing machine is working, the entire layer of cartons is pushed from the carton sorting machine onto the translation panel. The translation panel is moved to a suitable position directly above the pallet by the lifting mechanism and the geared motor. The piston rods of the cylinders extend, and the piston rods of the tilting cylinders extend. At this time, the entire layer of cartons is held by the clamping plates and the tilting baffle on all four sides. Then, the geared motor drives the chain to pull out the translation panel and return it to the initial position. The cartons fall onto the pallet below. Then, all the piston rods of the cylinders retract, and the palletizing of this layer is completed, and the next palletizing operation begins. This invention relates to a carton palletizing machine with a small footprint, simple operation, and wide applicability. Attached Figure Description
