proANT transport robot with lifting function for SLC
proANT 436 is an autonomous guided vehicles (AGV) developed by InSystems Automation for SLCs (small load carrier) with a surface area of 400 x 600 mm. Currently, three types of load handling devices can be integrated.
The lifting device allows for all three kinds of load handling devices adjustable transfer heights. The upper edge of the load carrier can vary between 440 and 750 mm. In every column, a spindle is integrated to lower or lift the load handling device. A toothed belt connects both spindles, which are synchronously driven. The transfer height can be customized upon request.
In order to cover long distances as fast as possible, the load handling device is lowered to its lowest point to keep its balance point as low as possible and secure the load. The small “nose” at the front piece of the robot is meant to ensure that the load does not skid ahead and fall off the conveyor, if an emergency stop is triggered.
The robot is made to be “mirrorable”. You can rotate the load handling device 180 degrees, so that the robot picks up loads from the back (current vehicles are delivered with frontal pick-up).
Passing load handling at passive conveyor belts
ProANT during load handling at a passive roller conveyor: Thanks to its lifting feature, the transport robot can pick up several SLC containers from a cost-effective gravity belt with several storage positions.
Active load handling with belt conveyor
The belt conveyor (width 400 mm) allows the transport of smaller loads (i.e. containers and small-sized boxes up to a surface area of 600 x 400 mm). The robot drives frontally to the conveyor of a machine or to a Pick & Drop Station. Via shared interface, the conveyor belts are activated at the same time and transfer (load and unload) takes place automatically. Of course you can also use the belt conveyor to put the load manually on the robot.
Passive load handling with skids
To simplify the load transfer, the robots uses the level adjustment feature. Instead of a belt conveyor, both skids are mounted on the carriages of the columns.Between these skids there is enough space for two conveyor belts (or wheel rails or fixed rails for storage) where a container can be placed. After skids are lowered, the vehicle can drive under the container. The box itself can stay where it is or be moved away.
Picking up a container works the other way around. Thanks to the upstands at the end of skids, no additional “nose” is necessary to avoid that the load drops down in case of an emergency stop.
Theoretically, the load handling of containers can take place forward or backward. The Pick & Drop stations can be totally passive as simple shelfs. However, only solid formats of load (400 x 600mm) can be carried.
Active load handling “skids” with small belt conveyor
This load handling device combines the two versions of load handling mentioned above. Therefore it provides different ways of usage. In mixed operations it can be driven to totally passive pick & drop stations or to stations with running bands or wheels and different heights. Here again, the robot can only carry solid loads (400 x 600mm).
