Understand The Cartoning/Case Packaging Machine in Post-packaging

For items that have been packaged once, in order to sell them in boxes, or to prevent damage during transportation and facilitate storage and transportation, they are often boxed and boxed in a certain way.

The machines that complete these processes are called cartoning machines that use cartons for secondary packaging, and those that use case (commonly used corrugated paper) for secondary packaging are called case packaging machines.

1. Work flow of automatic cartoning / case packaging machine

Case packaging machines mainly include small boxes (such as food, medicine, etc.), glass bottles, plastic bottles, plastic barrels, metal cans, flexible packaging bags and other packaging equipment.

The automatic case packaging machine can automatically shape and arrange the packaging materials, load them into the opened carton, and complete actions such as self-adhesive sealing. All actions are completed automatically. The basic process is picking up box boards → box forming → bottom folding → box transfer → product collection and packing → folding and sealing.

After collection and sorting of solid packaging such as bottles and cans, the gripper of the case packaging machine will grab a certain number and then directly load them into cartons, plastic boxes or pallets.

If partitions are required in the case, the accuracy of the case packaging machine is required to be higher. Flexible packaging product packaging generally adopts the method of box forming and material collection and filling at the same time, which can increase the packaging speed.

Most automatic case packaging machines adopt a new combination structure, including functional units such as case packaging device, arranging device, filling device and case sealing device, which complete corresponding functional actions respectively and are controlled by PLC + touch screen. It is equipped with safety devices for alarming and shutting down due to lack of material, and safety devices for not packing if there is no material.

Operation management is more convenient, production personnel and labor intensity are reduced, and it is an indispensable equipment for automated large-scale production.

2. Main forms of automatic cartoning / case packaging machine

The main forms of automatic cartoning machines currently available include horizontal, clamping, vertical drop, wrapping and pallet forming automatic cartoning machines. The transmission and control are mainly mechanical, pneumatic, and photoelectric integration.

(1) Horizontal type: It is mostly used for packing bags and block materials. The difference from other forms lies in the way the cartons are placed - the cartons lie flat and are opened into boxes before the items are packed.

(2) Clamping type: Robots or suction cups are often used to clamp packaging items to achieve automatic packing operations.

(3) Drop type: Mostly used for packaging items that are not easily damaged. They fall through the push rod or the movement of the pallet to achieve automatic packing.

(4) Wrapping type: After pre-folding the cardboard into a right angle, the items are pushed onto the cardboard using a push plate, and the box is made and wrapped according to the pressure line of the cardboard, thereby realizing automatic packing.

(5) Pallet type: A certain number of packaged items are placed on the pallet through a conveyor to achieve automatic packing.

Driven by the global manufacturing industry, fully automatic packaging machines are developing in a more efficient, intelligent, and environmentally friendly direction. Therefore, when developing cartoning machine products, it is necessary to fully reflect the features of multiple function switching, detachability, energy saving, and environmental protection.
