The Dynapac® is a three-at-a-time concrete products machine that produces up to 1800 units (eight inch or 200 mm equivalents) per hour. Production rates of the Dynapac are comparable to most four or five-at-a-time concrete products machines on the market. This production speed offers you the ability to manufacture concrete products faster with lower operating costs.
The Dynapac is cam driven to provide consistent speeds and movements. The precise indexing of the cams achieves uniform product quality even in variable operating conditions.
A variable speed frequency drive on the block moving device replaces the standard variable speed pulley drive. The variable speed frequency drive is remotely controlled from the SLC 5/05 control panel, compared to manually adjusting the variable speed pulley.
Precisely measured amounts of lubricant are automatically supplied to key bearings and pins. This routine maintenance function insures optimum performance of the Dynapac.
Allen-Bradley Control Panel
Many of the operating functions of the Dynapac can be easily adjusted by accessing the SLC 5/05 through the graphics display unit. This control panel automatically pinpoints problems and displays information for making corrections fast, and improves quality control.
Rotary Position Sensor
The sensor provides cam position information to the controller. This allows adjustments to be made to the machine set points while the concrete products machine is operating. Adjustments are made through the color graphics display unit.
A Bescodyne oil shear clutch/brake system is used on the main drive to provide quick and smooth starts and stops. The system is designed to handle the energy of rapid acceleration and deceleration, which allows for increased productivity. This clutch/brake also reduces stress on motors and other components of the machine, which extends the life of the components and reduces maintenance.
Standard Bescodyne vibration provides rapid engagement of vibrators to provide quick and smooth starts and stops, optimum compaction and consistent, uniform concrete products.
Automatic Feed Control
Automatic feed control adjusts the feedbox for uniform filling of molds. Routine maintenance is simplified with a standard C-face motor and separate gear box allowing independent replacement of either part.
AFC Smartpac® Vibration
By employing independent amplitude and frequency control, vibration is tuneable to specific molds and product requirements. The ability to control both amplitude and frequency results in more rapid compaction and quicker finish times than are obtained with conventional vibrating systems. Vibration can be engaged or disengaged multiple times within a single machine cycle. Mold life is increased with the use of AFC SmartPac vibration.
Posapac® Dual Vibration
Dual vibration utilizes a Bescodyne clutch/brake which allows the concrete products machine to use Posapac weights for short production orders. This is beneficial if several existing molds are owned with weights attached. AFC SmartPac can then be used for longer production orders or for manufacturing specialized products. This allows you to take advantage of reduced mold wear as well as independent amplitude and frequency control to facilitate improved feeding and finishing of products.
The frequency drive controls the main drive speed control so that specific segments of the machine cycle can be slowed down or sped up. This feature slows down the stripping speed without sacrificing overall cycle speed. The variable speed frequency drive is remotely controlled from the SLC 5/05 control panel.
Mold Insertion Device
The time needed to change molds is shortened and simplified with the mold insertion device. This pneumatic powered mechanism lifts/lowers the entire mold assembly off/onto the mold throat. The entire mold assembly is manually rolled into/out of the mold throat area.
Pallet Receiver Cam Inserts
Pallet receiver cam inserts allow for rapid height changeovers for certain mold configurations between 2″ and 7-5/8″. 60mm, 3-5/8″, 5-5/8″ and 7-5/8″ flat top molds can be run from the 7-5/8″ position and do not require moving the inner frame. Other heights may also be able to be run from this position dependent upon the mold configuration.
Vibrator Motor Air Bag Lifts
The vibrator motor air bag lift is an easy and quick way to raise the vibrator motors for mold changes. A lever operated pneumatic valve is moved to the up position allowing air to flow into the air bags. When the bags inflate both vibrator motors rise. This allows the operator to remove the belts and begin the mold change procedure. A lockout device is included for safety during maintenance.
The use of air compaction reduces finish time, which improves overall cycle time. Air cylinders supplement the pressure on the mold exerted by the weight of the machine head. The addition of compressed air brings the height pins together sooner, compacting the unit faster and more effectively.
Material build-up on pallets is automatically removed during each machine cycle. The tension forcing the scraper blade down on the pallet is fully adjustable to meet specific cleaning needs.
Automatic Stripper Head Clamp
Clamping of the stripper head is easily accomplished with the use of hydraulically actuated wedge assemblies.
