RapiD Vision Reject System (RVR)

The RVR diverts the products to the correct conveyor in the plant. Rejection is controlled automatically by the RVT. The RVR conveyors are controlled by the RVB.

Starting

1. Check that the main switch is switched on.
2. Check that both emergency stop buttons are released.
3. Check that the white air selector switch is set to Auto.

The white air selector switch has three positions:

Position	Function
Auto	The conveyors are controlled automatically based on the inspection result. This is the position for production.
Up	All conveyors move up and remain there, regardless of what the RVT or RVB detects.
Down	All conveyors move down and remain there, regardless of what the RVT or RVB detects.

The RVR conveyors start as soon as the green button of the RVB is pressed. See Start-up for the complete start-up procedure.

Rejecting

During rejection, the conveyor moves up and down. A sufficient gap between products is required so that the conveyor returns to its home position in time. Calculate the minimum gap as follows:

Minimum gap (mm) = belt speed (mm/s) / 2 + 15

Belt speed	Minimum gap
270 mm/s	150 mm

The product length does not affect this gap.

If several consecutive products are too close together, the software displays a notification.

Cleaning

Follow the general guidelines and remove and clean the conveyor belts at least once a week.

Maintenance

Component	Inspection	Action
Plastic modular belt (Intralox S560 Flat Top)	The belt elongates over time.	If the belt runs against the frame, remove one belt row.
Sprockets	Check the condition of the teeth during cleaning.	If several teeth are broken or worn, replace the sprocket.
Pneumatic cylinders	Periodically check for recurring oil residue on the piston rod.	If present, replace the cylinder.
