Focus on Palletizers
By Staff -- Modern Materials Handling, 1/1/2004
Palletize only in-spec items
A line of robotic palletizers easily and automatically
removes out-of-specification products without disrupting operations. Using data
from in-line checkweighers and metal detectors, the equipment identifies
specific packages that do not meet user-defined requirements. The robot then
rejects the item by one of two methods. It either stacks the item on a separate
reject pallet, or places it on a gravity conveyor for immediate inspection.

Handle 200 cases a minute
New to the high-speed 900 palletizer series are models
capable of handling more than 200 cases a minute. Many configurable options are
available, including a powered roller or modular plastic chain conveyor surface
and an in-line pattern formation for gentle product handling. Palletizers in the
series offer a variety of features such as stack-feed pallet dispensers with
fork-type separators, programmable logic controllers, as well as bi-parting
plates and articulate aprons.

Flexible palletizing
Flexible and powerful, a robotic palletizer manages
single and multiple products, mixed loads and complex stacking patterns
including overlapped bags. Fuji Ace Robot automatically places a pallet or
slip-sheet and stacks products from a single location. It performs up to 26
cycles a minute and uses a linear track design to reduce power consumption.

Make product changeovers quickly
Available in six configurations, the LSP-7 high-infeed
palletizer handles up to 40 cases a minute. Maximum load weight is 4,200 pounds.
Its user-friendly programming and multi-product memory allow users to make fast
product changeovers. Features include positive self-tracking infeed conveyor
metering belts, simultaneous row formation and layer building and a power roller
elevator bed.

Separate infeed for drums and pails
Drums and pails can be palletized on one machine with the 100-57DP automatic drum palletizer. Utilizing separate infeed conveyors, the system palletizes up to six drums a minute and up to 20 pails a minute. Various drum sizes and types including steel, plastic and fiber are accommodated.

Robotic palletizer fits in limited space
Designed for high-speed, heavy-payload palletizing, the
M-410iB robot handles cartons or bags weighing 220 pounds at rates of 20 cycles
a minute for cartons and 27 for bags. Its four-axis, modular construction with
an integrated mechanical and control unit makes the robot ideal in areas of
limited floor space. A maximum reach of approximately 10 feet allows the robot
to work on multiple lines at one time. Options include fork grippers for
handling trays, pails and open-end cases as well as end-of-arm tooling for
higher throughput applications.

Palletize 5,000 bags an hour
A family of modular palletizers handles between 600 and
5,000 bags an hour. Using a large variety of packing patterns, the Paletpac
series processes bags weighing more than 100 pounds. Low-speed belt conveyors
and gentle handling of the bags during push-off and calibration enable the
palletizer to form layers of bags without accumulating pressure. A set of
frequency controllers and servo drives ensure smooth operation of the machine.

Ideal for fragile products
To provide gentle case handling of fragile products, the
von Gal SPLX MK II palletizer utilizes simplified mechanical systems and a
device that cushions cases while turning them. The system's chain-driven live
roller also decelerates the cases prior to contact with the vertical case stops.
Any stacking pattern is possible including interlocking, column stack, overhung
and underhung loads. Depending on case sizes, stacking patterns and
configurations, the palletizer has a maximum speed of 50 cases a minute.

Palletizer manages four lines at a time
Working from as many as four infeed lines simultaneously, a robotic palletizer manages up to 880-pound loads. Each line can have either bags weighing between 50 and 100 pounds or boxes of any size. Fully automatic, the system places pallets, layer sheets and trays. Computer controls can be pre-programmed for each stock keeping unit.

Stage items for top productivity
The Robotic Palletizing Matrix (RPM) uses a single
conveyor infeed to stage items for robotic palletizing by overhead gantry. Cases
are conveyed and grouped with similar products within the gantry envelope. Once
the quantity of staged product equals the number of cases required to build a
unit load, the gantry end effector retrieves the cases and palletizes the load.

Palletize multiple configurations simultaneously
A gantry robotic order building system palletizes
multiple configurations simultaneously while also building orders in load buffer
locations or accumulation cells. The gantry design allows the system to be
easily adapted to handle a variety of products including totes, cases and pails.
The custom-designed end effector picks finished products from flow racks and
product infeed conveyors.

Continuously feed cases to form layers
A case palletizer featuring an overhead pusher bar
continuously feeds cases as pallet layers are formed. It is equipped with an
Intelligent Control programmable logic controller and constructed of heavy-gauge
steel.

Palletizer/de-palletizer is compact
The K-Bot is a four-axis, floor-level system that runs
single and dual line applications and serves as both a palletizer and
de-palletizer. It moves up to 175 pounds at a rate of 10 cycles a minute. A
compact 62x104-inch footprint allows for pallet sizes of up to 48x48 inches and
unit loads up to 72 inches high. Pre-defined pack patterns are programmed into
the operator interface, enabling easy changeovers.
