The ProCo flexible tipping and combining machine is a modular designed and constructed unit that is capable of accommodating a range of product sizes and is easy to size/format change.
The ‘Flexible Tipping and Combining Machine’ consists of two modules with the option of additional modules as required.
The first modular section as shown on the right in the photographs is for the feeding of rods (filter or tobacco) and has a tray station, hopper, single rod feed, and feed drums with a transfer system to the subsequent modular section for the product assembly.
The second modular section is for the feeding of rods (filter or tobacco) and has a tray station, hopper, single rod feed, cork paper bobbin, cork drum, ‘Hauni’ type glue system, and transfer drums which includes the final cut drum and knife assembly.
The final product is transported out of the machine on a low level exit conveyor that has a ‘hand catching’ station. As an option if required the machine can be equipped with a conveyor to link to a tray filler.
The unit is fitted with camera inspection for checking wrap and assembly and defective product is ejected.
The unit is set up to suit a product size that is advised with the option of change parts as described above for different sizes.
The machine as standard includes the ‘standard’ Hauni type glue system for the application of adhesive to the tipping paper. The glue roller is driven by a servo motor and control to enable both print and wipe glueing to be achieved. Adjustments can be made via the HMI.
A unique design has been utilised for the cork drum which enables adjustment for different suction port positions.
The machine design enables each tray station and rod feed system to be mounted on a sub plate which is easily and accurately adjusted for position. Furthermore the same design criteria has been applied for the cork bobbin and cork drum assembly which are mounted on a sub plate for easy and accurate adjustment.
Additionally the final cut drum and knife assembly are adjustable for product position.
The second modular section has a servo motor and control for the cork bobbin in order to be able to produce patch lengths between 19mm and 30mm. The patch length setting/adjustment is achieved via the HMI.
Preheaters are installed before the curling bars.
The machine has a B&R IPC based control system, servo motors and drives with B&R HMI
For alternative sizes of product the hopper feed section and drums are pre-assembled for different diameters.
Based on proven technology. Modular design and construction. Drums where possible are machined to enable more than one diameter to be accepted for quick changes. A unique design has been utilised for the cork drum which enables adjustment for different suction port positions.
As standard the product size range that can be accommodated with change parts is as follows: • Finished product length: 40mm to 120mm • Tobacco rod length: 20mm to 120mm • Filter tip length: 20mm to 120mm • Product diameter: 5mm to 10mm • Paper width: 10.0mm to 82.0mm
• 6 station pneumatic indexing tray rack • Quick release and ‘easy’ timing mechanisms to enable full format changes in under 1 hour • Paper bobbin, cork drum and gumming assembly mounted on a sub plate enabling accurate positional adjustment along linear rails via a hand wheel with position indicator • Servo driven glue roller to enable both print and wipe gumming • Servo driven paper pulling roller to control patch length • Integral vacuum pump and fan unit • High speed camera inspection and ejection of incorrectly wrapped product • 15” (381mm) HMI and B&R IPC based control system as standard • Cork drum adjuster and scale • Rolling drum incorporating reject • Clutches to engage/disengage drives to enable timing for delivery of product • Adjustable drum and cutting position of final knife • ‘Butterfly’ valve adjusters for increased suction level control
Sensors are installed for the following: • Main motor clutch • Hopper low • Refuser jam • Missing product – hopper • Missing product – upstream • Bobbin speed sensor (to detect low bobbin) • Paper drive engaged • Glue level • Glue wave • Glue pot lever • Glue pot location • Tipping paper break • Platen brake 1 and 2 • Rolling plate jam • Product inspection (Keyence camera) • Print registration • Air pressure
