Comparison of Cap orter models:

There are different types of cap sorters used in industrial applications, each with its own advantages and limitations. Here's a comparison of some commonly used cap sorting systems:


Vibratory Cap Sorters:

  • Operation: Vibratory cap sorters use vibration to orient and feed caps into the production line. They rely on the natural characteristics of the caps to align them correctly.
  • Advantages: Vibratory sorters are versatile and can handle a wide range of cap sizes and types. They are relatively simple to operate and require minimal maintenance.
  • Limitations: They may have limitations in sorting certain types of caps, such as those with complex shapes or irregularities. Vibratory sorters may also be affected by factors like humidity or cap surface conditions.

Centrifugal Cap Sorters:

  • Operation: Centrifugal cap sorters use centrifugal force to sort and feed caps into the production line. Caps are loaded into a rotating disc, and the centrifugal force pushes them to the outer edge where they are released.
  • Advantages: Centrifugal sorters are highly efficient and can handle high-speed production lines. They can sort caps of various sizes and shapes reliably.
  • Limitations: Centrifugal sorters may require more frequent adjustments and maintenance compared to vibratory sorters. They may also have higher initial costs.

Lifting Cap Sorter:

  • Operation: Lifting cap sorters use a lifting mechanism to elevate caps from a bulk supply and align them before feeding into the production line. The caps are lifted vertically and released into a chute or conveyor.
  • Advantages: Lifting cap sorters are suitable for handling caps of various sizes and shapes. They can often accommodate larger-capacity bulk supplies and offer high sorting accuracy.
  • Limitations: Lifting cap sorters may have higher initial costs compared to vibratory or centrifugal sorters. They may also require more space due to the vertical lifting mechanism.

Vertical Wheel Cap Sorter:

  • Operation: The vertical wheel cap sorter uses a rotating wheel with pockets or cavities to hold and sort caps. The wheel rotates vertically, allowing caps to be loaded, sorted, and released into the production line.
  • Advantages: Vertical wheel cap sorters are known for their high-speed sorting capabilities. They can handle a large volume of caps per minute, making them suitable for high-speed production lines. They are also versatile and can handle caps of various sizes and types.
  • Limitations: The vertical wheel cap sorter may require more frequent cleaning and maintenance due to the rotating wheel mechanism. It may also have some limitations in sorting caps with complex shapes or those that are easily damaged.

Air Jet Cap Sorters:

  • Operation: Air jet cap sorters use directed air streams to separate and orient caps. The air jets blow away misaligned caps, allowing properly oriented caps to pass through.
  • Advantages: Air jet sorters are gentle on caps, making them suitable for fragile or sensitive caps. They can handle a wide range of cap sizes and shapes and offer high sorting accuracy.
  • Limitations: Air jet sorters may require higher air pressure and filtration systems. They may also be limited in sorting caps with certain characteristics, such as lightweight or irregularly shaped caps.

Optical Cap Sorters:

  • Operation: Optical cap sorters use cameras and sensors to identify cap orientation and position. The system analyzes the captured images and activates mechanisms to sort the caps accordingly.
  • Advantages: Optical sorters offer high accuracy and flexibility in cap sorting. They can handle caps with various shapes, sizes, and colors. They are also capable of detecting defects or foreign objects.
  • Limitations: Optical sorters tend to be more complex and expensive compared to other types. They may require regular calibration and adjustments to maintain accurate sorting.

It's important to note that the specific design and features of vertical wheel cap sorters can vary among manufacturers. Some models may include additional features such as cap orientation mechanisms or adjustable settings to accommodate different cap sizes and sorting requirements.

When considering a vertical wheel cap sorter or any cap sorting system, it's essential to evaluate your production line requirements, such as production speed, cap characteristics, and desired sorting accuracy. Consulting with equipment suppliers and manufacturers can provide more detailed information on the capabilities and suitability of specific models for your application.

The choice of cap sorter depends on factors such as the specific requirements of the production line, cap characteristics, production speed, budget, and available space. It is essential to consider the specific needs of the application and evaluate the advantages and limitations of each type before making a decision.

It's important to note that different manufacturers may offer variations of cap sorting systems, and the features and capabilities can vary. The choice of cap sorter depends on factors such as the specific requirements of the production line, cap characteristics, production speed, budget, and available space. Evaluating the advantages and limitations of each type in relation to your specific needs will help determine the most suitable cap sorting system for your application.


Cap sorting mode will be applied and coordinated with different speed and cap shape based on each custom requirement.
