AC1 Automatic Cap Tightening Machine

The Asset Packaging Machines AAC-1 Auto cap tightener is designed to mount on to continuously running slat-type conveyors and is capable of tightening a vast range of threaded closures at rates of up to 60 units per minute.

Containers arrive at the machine by an inline conveyor, with caps pre-placed upstream either manually or by automatic cap placement equipment. A photoelectric sensor detects the presence of a container and initiates machine operation through an electronic or pneumatic timer control unit.

The control unit enables fast set-ups and simple fine tuning of cycles through its programmable timer and digital display or pneumatic controls. The delay and operating dwell times of the cap tightening chuck and the container clamping jaws and gating can be freely set by push buttons or knobs on the front panel.

The twin timer control unit with separate settings for chuck and jaws/gates, provides substantially increased flexibility when running bottles at higher speeds and /or with difficult components.

The AAC-1 Auto bottle capper is supplied complete with a conveyor or conveyor mounting frame, pneumatic container gating and clamping devices, and aluminium clamping jaws (with non-marking friction facing) of either the general purpose V-Jaw type or contoured to the individual container profile. Jaws for glass containers are supplied with plastic slippers to prevent the container scoring the conveyor.

Our range of 5 standard interchangeable tightening chuck sizes and 3 standard liner materials will handle most capping applications. Chucks are also available for specialised closures such as Tamper-tel, eyedropper etc.

For trigger pack sprays, cream dispensers, mist pumps and other closures which cannot be tightened from above the Asset Pumptite unit is available as a bolt on optional item.

Asset can supply the AAC-1 Auto ready for the customer to adapt to their existing conveyor lines or we can provide a complete on-site installation service including conveyor mounting, guide rails modifications etc.
