Main components and functions:
- Infeed conveyor: Ensures a constant product supply to the machine.
The conveyor has 3 sensors per lane to detect product presence,
allowing the machine speed to be adjusted.
- Metering wheels: Synchronize the product flow with the machine.
- Grouping module: Assembles the product packages.
- Front conveyor: Transports the products and cartons from the
grouping module to the rear conveyor.
- Carton magazine: Holds the cartons, which are then removed
individually by the carton separator. Carton feed is driven by belts
and a gear motor, controlled by a sensor in the lower front area.
- Carton separator: Removes individual cartons from the magazine and
places them on the belt onveyor when the presence of a product is
detected by a photoelectric sensor. Cartons are picked up using vacuum
suction cups supplied by a vacuum pump.
- Carton transport: Consists of two belts fitted with drivers,
ensuring the carton is conveyed in phase with the product package. A
photoelectric sensor detects a carton that has been placed.
- Upper transport device: Conveys the products and carton from the
front conveyor to the outfeed belt. Height adjustment is automatic,
using a photoelectric sensor and a counting disc.
- Rear conveyor: Transports the products together with the cartons
from the front conveyor to the outfeed belt, and aligns the two side
flaps of the carton to each other.
- Drive unit: Provides the mechanical drive for the various machine
modules and their synchronization. Mechanical protection of the
modules is ensured by a torque limiter.
- Hot glue unit: Applies a hot glue track. Glue is only applied when
the motor is running and a pack is present, as detected by a
photoelectric sensor. Heat-up time for the hot glue unit is
approximately 45 minutes. The position and length of the glue track
are controlled via the PLC in the control cabinet and can be set on
the touch panel.
- Gluing when machine is stopped: If the machine is stopped during a
processing cycle, the last glued pack is still closed by a pneumatic
cylinder.
- Dividing switch: Divides the packs from one lane into two lanes
according to the format. Can be adjusted in width according to the
format.
