Pharmaceutical Seal Bottle Capper

ST Series

Our ST Series Pharmaceutical Seal Bottle Capper is specifically designed for the application of crimp seal closures for pharmaceutical applications at speeds in excess of 600 vials per minute. Its small footprint allows the Pharmaceutical Seal Bottle Capper to fit virtually every line. Quick change pressure blocks and micrometer positioned tuck rail provides for fast, positive changeover for multiple size vials and seals. Clean design and full 304 stainless steel construction make the Pharmaceutical Seal Bottle Capper the ideal crimping machine for pharmaceutical lines.

The pharmaceutical seal bottle capper ST Series ranges in speed from 10 to over 600 vials per minute.  If you are looking for a bottle capper to meet your specific requirements, the ST Series offers several features to meet specifications.  With a high speeds, the ST Series is not only fast, it is accurate and effective.  Using the maximum use of 304 stainless steel, the pharmaceutical seal bottle capper is durable, sturdy, and built for a long lifespan.  The rugged construction of the ST series is build for several years of three shift operational capabilities.

In addition to the standard machine components that many of our competitors list as optional, Fowler offers a wide selection of unique Options or Upgrades. Every Option and Upgrade listed has proven to provide value well beyond its initial cost and was developed to meet a very specific customer or market need. If you require a feature that is not listed below, we are interested in learning what we can do to help satisfy your need.

  • Allen Bradley 5/05 (5/04 is standard): Available to allow Ethernet communications with capper. Option includes Ethernet capable interface screen and hub
  • Allen Bradley PLC-5: Available as required to conform to plant standard. Not recommended as current technology is superior and less costly
  • Allen Bradley Control Logix: Current state-of-the-art Programmable Logic Controller. Provides for expanded control functions. Recommended for complex machines equipped with multiple options and electronic cappers
  • Allen Bradley Flex I/O : I/O Module to provide for simplified wiring of I/O from capper to the main control panel. Also available for use on filler where synchronization is provided
  • Allen Bradley PanelView 1000 (standard on some models): PanelView 700 Operator Interface touch screen is the standard on machines where machine functions require limited HMI. For machines which require greater detail and depth, the AB PanelView 1000 is supplied as the standard. All Fowler supplied touch screens are housed in a NEMA 4X stainless steel box with hard wired switches for Power On/Off, Start, Cycle Stop, Jog and E-Stop functions
  • Allen Bradley VersaView CE 1250H with "On Board" machine manual: VersaView CE1250 Operator Interface touch screen is available to provide expanded man/machine interface capability. Windows CE based platform allows for "On Board" machine manual as well as true graphic representation of fault condition, such as identifying which guard door is creating an "open guard door" fault. All operator interfaces include hard wired switches for the most common controls to reduce wear on the touch screen
  • Bottle Conveyor Infeed and Discharge Cross-Overs: Fowler/Zalkin cappers are equipped with a fixed length of continuous bottle conveyor channel through the capping machine which is suitable for use with existing or proposed up/down stream conveyor chain type. This conveyor channel is supplied to functionally and "aesthetically" face mount to the existing up/down stream channel and as part of the standard capper, no chain or drive/gear-motor is provided. Should the line layout dictate, the capper can be optionally supplied with the conveyor assembly to move containers from an upstream conveyor, onto the through conveyor of the capper and then onto the downstream conveyor. The conveyor is designed to side transfer without dead plates and is supplied as turn-key, with chain, drive and gear-motor, side transfer rails and integration with capper for run condition control. Total overall length is quoted per foot as required
  • Bottle Rejection and Sampling: Fowler has equipped cappers with our bottle rejection and sampling option for line speeds up to 550 per minute. Higher speeds are subject to container testing. The option consists of sensors to detect missing, high or cocked caps where the traditional mechanical capper is provided or the added feature of "out of torque" available with the electronic capper. Vision can add additional detection features. The unique Fowler Bottle Rejection and Sampling option consists of the necessary sensors, a modular rejection assembly consisting of three or four linear motors which form a secondary back guide to the capper discharge star when actuated in series, a secondary rejection conveyor and all related control software. The option includes verification sensors to assure that a bottle sending a reject signal is placed onto the reject conveyor. Incorporated into the option is the Sampling feature which allows for one bottle from each head, one bottle from one unique head, or multiple bottles from one unique head, to be diverted to the reject conveyor for sampling
  • Cap Inspection (vision): Although detecting missing, high or cocked caps can routinely be accomplished using sensors, occasionally a more sophisticated evaluation of the cap application is required. Fowler has integrated vision systems and the related control software on machines running at speeds up to 550 per minute to check various criteria for proper cap application. Coupled with the Fowler Rejection option, the Vision System provides a powerful tool for assuring quality packaging
  • Corrosion Resistant Construction: Cappers installed in harsh environments, such as hot fill, acidic products, with caustic wash downs are typically constructed with the maximum use of stainless steel, either 304L or as required, 316L. Further, to keep high pressure, hot caustic wash down from causing lubrication break-down, additional attention to the upper turret shielding construction is provided, including venturi steam extractors to pull steam away from the upper turret chamber. Finally, the base is constructed such that all table top pass through holes are "O" ring sealed as are the base access doors, to provide a six sided, sealed base in which the main drive components are housed. Optional on some models, corrosion resistant construction (using 304L) is standard on "food grade" and hot fill juice/isotonic packaging lines where cap steaming is typically used
  • Light tower: with or without audible
  • Menu Selectable Automatic Height

  • No Bottle - No Cap
  • Quick Release Cap Handling Components
  • Self-lubricating Head Slides: Nitrate treated or stainless steel
  • Six Sided, Sealed Base
  • Stainless Steel Wireway Connection: Capper to main panel
  • Strongarm XYZ Swing Arm: The Strongarm brand operator interface mounting system is well known in the industry as a durable HMI mounting system which provides the maximum range, in three dimensions, of interface placement for operator convenience. The unit can be mounted on any of the four machine frame posts or turret support cross members
  • Telescoping Cap Chutes
