    Available Upgrade Options – Cap Sorting Elevators and Vibratory Bowls

    Cap Sorting Elevators and vibrator bowls are the most common and economical cap sorting systems used with fully automatic capping machines. Capable of handling multiple different cap sizes. The operator simply loads all of the caps into the hopper, The caps are then automatically sorted into a chute and applied onto the bottles or containers.

    Cap Sorting Elevator

    The cap sorting elevator comes in multiple sizes depending on your cap diameter.  Not all caps are able to be sorted in a cap elevator.   The elevator feeds the caps up a belt with slats in a way that most caps are properly oriented.  The ones that get through are rejected in a reject chute.  The caps are then fed into a chute the leads to the capper.

    Specifications

      • For Flat caps up to 5” diameter
      • 6 Cubic Ft hopper with 12” wide chain
      • Low level sensor to automatically start / stop the feeding of the caps into the cap chute
      • Dial indicators or rulers for quick change over
      • Oversized elevators available

    Vibratory Bowl

    Vibratory Bowls are perfect for special types of caps that cannot be fed in a cap sorting elevator.  The bowl is tooled to meet the needs of your cap.  Not all caps are able to run on the same bowl.  The bowl can be placed on top of certain cappers or on its own base.  A properly tooled bowl will orient the caps so that they are all oriented in the same way.  They are then fed into a chute that leads to the capper.

    Specifications

      • Available in either 24” or 30” diameter
      • Stainless Steel construction with Anodized parts
      • Low level sensor to automatically start / stop the feeding of the caps into the cap chute.
      • Manual or motorized up and down options

    Everything You Need to Know — No Surprises.

    We believe buying equipment should be simple. Here are answers to the most common questions from packaging teams like yours.

    Spindle Capper FAQ
    What is a spindle capper?

    A spindle capper is an automatic bottle capping machine that applies and tightens screw caps using multiple sets of rotating spindle wheels. It is one of the most common capping solutions for high-speed packaging lines because it can continuously cap bottles without stopping.

    When should I choose a spindle capper instead of a chuck capper?

    Spindle cappers are ideal for high-volume production and applications where continuous operation and throughput are the priority. Chuck cappers provide more precise torque control and are often preferred for applications requiring exact torque specifications or handling specialty closures.

    What types of caps can a spindle capper handle?

    Aesus spindle cappers can handle a wide variety of screw caps, including:

    • Flat caps
    • Ribbed caps
    • Child-resistant caps (depending on the application)
    • Some others - Contact Aesus to confirm.

    Machine configuration and testing determine compatibility with specific cap designs.

    What types of containers can Aesus spindle cappers process?

    Aesus spindle cappers can accommodate many container styles, including:

    • Plastic bottles
    • Glass bottles
    • Jars
    • Round containers
    • Oval containers
    • Square containers
    • Custom-shaped containers

    Optional change parts and adjustments allow the machine to handle different sizes and formats.

    Contact Aesus to have your container assessed for compatibility.

    How fast can an Aesus spindle capper operate?

    Depending on the model and application, Aesus spindle cappers can achieve speeds of up to 120 bottles per minute. Actual production rates depend on bottle size, cap style, product characteristics, and line configuration.

    Can the spindle capper automatically feed caps?

    Yes. Aesus spindle cappers can be equipped with a cap sorting elevator or an optional vibratory bowl feeder to automatically orient and deliver caps to the capping machine for fully automatic operation.

    Can a spindle capper be integrated into an existing packaging line?

    Yes. Aesus spindle cappers are designed for seamless integration with existing conveyors, fillers, labelers, induction sealers, shrink labelers, and other packaging equipment.

    What industries use spindle cappers?

    Aesus spindle cappers are commonly used in:

    • Food and beverage
    • Pharmaceutical
    • Nutraceutical
    • Cosmetic
    • Personal care
    • Household chemical
    • Industrial chemical

    applications requiring reliable, high-speed automatic screw cap application.

    Can Aesus spindle cappers handle multiple bottle sizes?

    Yes. The machines are designed for quick changeovers and can be adjusted to accommodate different bottle diameters, heights, and cap sizes, making them suitable for manufacturers producing multiple SKUs.

    What is a pre-spin station and when is it beneficial?

    A pre-spin station provides positive control of the cap before it enters the spindle tightening wheels, ensuring proper cap placement on the container. It is especially beneficial for large containers or applications where cap alignment is critical, helping improve capping consistency before torque is applied.
