A labeling machine is a device used to apply labels to objects. It usually consists of a robotic arm, a control system and a device for supplying labels. Labeling machines have been widely used in various industries. Different product labeling objects have different types, material shapes, and requirements. In order to meet the labeling needs under different conditions, there are different types and varieties of labeling machines.
Types of labeling machines
According to the degree of automation
According to labeling function
According to the running direction of the container
According to the type of label
1. According to the degree of automation
According to the degree of automation, labeling machines are divided into manual labeling machines, semi-automatic labeling machines, and fully automatic labeling machines.
- Manual labeling machine: Manual operation is required to complete the label pasting process. Usually controlled by a handle or handle, the label is applied by manual pressing or turning.
- Semi-automatic labeling machine: combines manual operation and partial automation technology. They usually have electronic control systems and auxiliary devices such as conveyor belts to improve efficiency and reduce labor costs.
- Fully automatic labeling machine: completely relies on computer control and advanced sensing technology to operate. These devices are able to recognize objects of different sizes, shapes and materials and paste them quickly and accurately according to preset programs.
2. According to labeling function
According to the classification of realizing different labeling functions, labeling machines are divided into flat labeling machines, side labeling machines, corner labeling machines and rotary labeling machines.
Flat labeling machine
The flat labeling machine can label and film on the upper flat and upper curved surfaces of work pieces, such as boxes, books, plastic shells, etc.
Working principle: The sensor detects the passing of the product and transmits a signal back to the labeling control system. At the appropriate position, the control system controls the motor to send out the label and attach it to the position of the product to be labeled. The product flows through the labeling device, and the label is firmly covered. The attaching action of the label is completed.
Side labeling machine
The side labeling machine can be used for single-sided and double-sided labeling of flat bottles, round bottles, and square bottles of different sizes.
Working principle: The sensor detects the passing of the product and transmits a signal back to the labeling control system. At the appropriate position, the control system controls the label to be sent out and attached to the position of the product to be labeled. The product flows through the labeling device, and the label is covered and attached to the product. on, the attaching action of a label is completed.
Corner labeling machine
The purpose of the corner labeling machine is to label the corners of the upper and side surfaces of the box to prevent disassembly.
Working principle: The sensor detects the passing of the product and transmits a signal back to the labeling control system. At the appropriate position, the control system controls the motor to send out the label and attach it to the product to be labeled. The product flows through the labeling brush and the label is brushed. , the attaching action of a label is completed.
Rotary labeling machine
The rotary labeling machine is designed for products with circular motion, such as cylindrical, square, rectangular bottles, glasses, vials, cans, flasks, special-shaped containers, etc. It is widely used in wine, beverage, food, cosmetics and chemical industries, etc.
3. According to the running direction of the container
According to the running direction of the container, labeling machines are divided into vertical labeling machines and horizontal labeling machines.
Vertical labeling machine
Vertical labeling machine means that the material is in a standing position when labeling, which is common in larger bottles, boxes and other materials.
Horizontal labeling machine
Horizontal labeling machine means that the material is in a lying position when labeling. It is common in small bottles, especially oral liquid bottles, etc.
4.According to the type of label
According to label type, labeling machines are divided into wet glue labeling machines, hot melt glue labeling machines, self-adhesive (pressure sensitive) labeling machines and shrink sleeve labeling machines.
Wet glue labeling machine
This wet glue labeling machine, also known as adhesive labeling machine, is suitable for glass bottles and plastic bottle labeling machines. It can automatically spray ordinary label paste and label the bottle surface. Widely used in beverage bottles, medicine bottles, and wine bottles, this machine is suitable for different bottle types and label sizes.
Hot melt adhesive labeling machine
Since the adhesive needs to be heated and melted before it can be used, this labeling machine is only suitable for certain specific packages due to its own characteristics. At present, it is mainly used for beverage packaging; such as: mineral water, functional drinks, carbonated soft drinks, etc. It mainly uses continuous linerless labels. This kind of label is divided into disc type hot melt adhesive labeling machine and box type hot melt adhesive labeling machine. The disc type means that the labels are in a roll, and the box type means that the labels have been cut one by one according to the needs. Well packaged in a corrugated box.
Self-adhesive (pressure sensitive) labeling machine
Utilizing the pressure-sensitive characteristics of its pressure-sensitive adhesive, it can be attached to the object under the action of micro-pressure. Pressure-sensitive label materials have the advantages of being green and environmentally friendly, capable of automatic and efficient labeling, exquisite and beautiful, and are widely used.
Shrink sleeve labeling machine
The most important part of the shrink sleeve labeling machine is the center column. The label is placed on the center column. The product flows through the conveyor line. The sensor detects the passing of the product and sends a signal back to the sleeve labeling control system. The system controls the corresponding motor rotation at the appropriate position. The cutter cuts the label, and then the label falls on the product. The product passes through the shrinking furnace, and a finished product with the label is completed.
In summary, by understanding the different types of labeling machines and choosing the right one based on the degree of automation, labeling capabilities, label type, and direction of travel of the container, companies can make informed decisions that meet their specific labeling needs. With the right labeling machine, companies can streamline the labeling process and achieve consistent, high-quality results on product packaging.
