As an expert in the field of precision packaging machinery, Hansheng Automation will now provide an in-depth analysis of two representative pieces of equipment: the Automatic Vertical Round Bottle Labeling Machine and the Servo Flat Label Applicator.
Automatic Vertical Round Bottle Labeling Machine
For round bottles (such as medicine bottles, wine bottles, and cosmetic bottles), the vertical round bottle labeling machine is the most widely used type. It works by rolling the label perfectly onto the curved surface of the bottle during the upright conveying process.
Features and Core Technologies
High Adaptability and Ease of Adjustment
This equipment can perform not only full-circumference labeling but also semi-circular labeling. This is achieved through its "three-bar adjustment mechanism" and its fine-tuning capabilities across eight degrees of freedom (x/y/z axes and tilt). The core of these fine-tuning capabilities lies in its tightly fitted lead screws, guide rails, and locking elements. These components possess extremely high machining precision and wear resistance; otherwise, positioning deviations would occur during frequent product changes and adjustments.
High-Quality Labeling and Intelligent Control
The Automatic Vertical Round Bottle Labeling Machine features a spring-loaded labeling tape design that smoothly smooths labels through gentle contact. Simultaneously, a sophisticated electronic control system comprised of a Panasonic PLC, a touchscreen, and a German Leuze photoelectric sensor perfectly controls the equipment. It automatically tracks products and identifies labels. This feature hinges on the reliability of the mechanical transmission system, including high-quality bearings, wear-resistant materials, and a robust machine structure used in components such as the bottle-separating mechanism, conveyor chain, and labeling rollers.
Scope of Application and Key Technical Parameters
1.Applicable Labels: Self-adhesive labels, self-adhesive films, electronic supervision codes, barcodes, etc.
2.Labeling Accuracy: ±1mm (excluding product and label inherent errors).
3.Labeling Speed: 80-150 pieces/minute (strongly correlated with product size).
4.Machine Material: Stainless steel and high-grade aluminum alloy, meeting GMP production requirements.
Servo Flat Label Applicator
For flat objects such as cardboard boxes and packaging cartons that require labeling, especially in applications with extremely stringent requirements for speed and accuracy, such as drug regulatory codes and electronic product traceability codes, the Servo Flat Label Applicator is the best choice.
Features and core technologies
Servo Drive
Unlike traditional stepper motors or ordinary motors, high-performance servo motors from Japan can precisely receive and execute every pulse command from the PLC, achieving closed-loop control of the label dispensing speed, position, and torque. This means that it can complete instantaneous and precise positioning, label dispensing, and attachment at extremely high conveying speeds (up to 35 meters per minute), achieving a production capacity of up to 200 pieces per minute.
Intelligent Collaboration and Synchronization
This machine utilizes an intelligent microcomputer control system to achieve real-time synchronization between labeling speed and conveyor belt speed. Regardless of changes in production line speed, it ensures precise and consistent label placement. The entire machine is constructed from T6 aluminum alloy and SUS304 stainless steel, not only to comply with GMP standards but also to guarantee the high rigidity and stability of the frame. A stable mounting base is a prerequisite for the normal operation of all sensors and actuators, enabling the machine to achieve high precision.
Scope of Application and Key Technical Parameters
1.Applicable Objects: Labeling of flat or slightly curved surfaces such as cardboard boxes, packaging cartons, and plastic boxes. Suitable for electronic supervision codes and Level 1/2 codes.
2.Labeling Accuracy: ±1mm (depending on product characteristics and flatness).
3.Labeling Speed: Up to 200 pieces/minute (related to label and product length).
Core Configuration: High-performance servo motor system.
Automatic Vertical Round Bottle Labeling Machine VS Servo Flat Label Applicator
| Comparison Dimension | Automatic Rolling Vertical Round Bottle Labeling Machine | Servo Flat Labeling Machine |
|---|---|---|
| Application Object | Round bottles, cylinders | Cartons, packaging boxes and other flat surfaces |
| Core Drive | PLC + Stepper/General Motor Control | PLC + High-performance Servo Motor |
| Core Advantages | Strong universality, easy adjustment, high cost performance | Extremely fast speed, extremely high precision, suitable for high-demand applications |
| Technical Barriers | Precision and stability of mechanical adjustment mechanism | Algorithm and response speed of servo electric control system |
It is clear that both types of equipment have their own advantages and disadvantages. However, as a supplier of precision mechanical parts, we understand that the stability and characteristics exhibited by these devices all stem from the collaborative work of hundreds of precision parts within them.
What is the true core of equipment selection?
Beyond the specifications provided by your supplier, as customers, we should focus more on the precision, materials, and durability of its mechanical parts.
1. A label peeler that is not sharp enough or has poor surface finish may cause label dispensing problems.
2. A label roller with slight runout or wear may cause label wrinkles.
3. A set of transmission gears or timing pulleys with backlash will prevent the high precision of the servo motor from being fully utilized.
