Even though Dorner provides the most extensive offering of standard conveyors, modifications and custom engineered solutions are sometimes needed to achieve the optimum conveyor package.
Modular Plastic Belt
Heavy loads, accumulation, drainage or air flow, and the need to transport around a curve are all reasons to use Modular Plastic Belt. The 3200 Series MPB Curve Conveyors is available to solve these and other application requirements.
Work Holding & Elevation Changes
Holding parts to the belt for elevation changes or controlled positioning can be achieved in a variety of ways.
- Magnetic Conveyors
Holding parts to the belt for elevation changes or controlled positioning can be achieved in a variety of ways.
- Holds Ferrous parts fast to the belt
- Ideal for elevation changes or part holding
- Can be used in upside down applications
- Strength and size of magnetic field is designed per application
- Vacuum Conveyors
Vacuum conveyors are made by perforating the belt and drawing air through grooves in the bed of a standard conveyor.
- Holds flat parts of any material fast to the belt
- Ideal for elevation changes or part holding
- Can be used in upside down applications
- Vacuum area required is designed per application
- Special Cleated Conveyors
Cleats are applied to the conveyor belt at any spacing and in a variety of heights and cutouts.
- Contains small parts for elevation changes
- Creates pockets for controlled separation of product
- Available in urethane belt and plastic chain styles
- Fixed guides or integral sidewalls are available
- Fixtured Conveyors
Precision fixtures can be mounted to certain belt types
- Provides product specific nesting
- Ideal for accurate part location in inspection or assembly applications
Product Flow
Controlling the continuous flow of products through the line is critical to maintain efficiency.
- Diverters & Gates:
Product can be diverted using static guides and plows or dynamic gates and paddles.
- Changes product direction to single or multiple locations
- Often used to meter flow to specific areas or to separate products based on certain attributes
- Control via proximity switches, photo eyes and counters is typical
- Pushers
Pushers can be mounted at the side of the conveyor or overhead depending upon the product and stroke length required.
- Moves product from the conveyor perpendicular to the flow
- Used to remove or transfer parts to other equipment or conveyors
- Also used to create horizontal stacks of products
- Control via proximity switches, photo eyes and counters is typical
- Lane Guiding
Multiple product lanes can be created across the width of the belt.
- Accumulate large quantity of product
- Divert product across lanes
- Merge multiple lanes to a single lane
- Support unstable product
Product Positioning
Product positioning when stopping is often a necessity for processes such as inspection, assembly or feeding into equipment.
- Servo Drives
Servo drives can be mounted to the conveyor using standard or modified hardware.
- Accurately stops the conveyor to provide precise part location
- Provides controlled acceleration and deceleration
- Great for very accurate assembly operations
- Timing Belt Conveyors
A large timing belt can be used as the actual conveyor belt in conjunction with a toothed conveyor pulley.
- Provides excellent belt movement control
- Used for accurate part or fixture positioning
- Can be used with a variety of drives, including servo drives for very accurate indexing and positioning
- Shaft Encoders
Encoders can be mounted to the drive shaft of the conveyor.
- Senses shaft rotation or counts pulley revolutions
- Can sense excessive drag on the conveyor belt
- Counts revolutions for accurate control of the belt in feeding or indexing applications
Line Access
Access to equipment, work areas and the efficient movement of personnel can be provided by utilizing lift gates and pivot conveyors in the conveyor line.
- Lift Gates
A standard conveyor can be mounted to a lift gate base creating a conveyor gate that is easily lifted open for walk-thru access.
- Counterweights create easy opening of the gate
- Interlock switches and a timer allow the conveyor to clear before the gate is opened preserving full product control
- Product flow can automatically resume after the gate is closed
- Pivot Conveyors
A standard conveyor is mounted to a pivot base to allow the conveyor to swing out of the way and provide walk-thru access.
- Interlock switches and a timer allow the conveyor to clear before the gate is opened
- Product flow can automatically resume after the conveyor is returned to the inline position
In-Line Inspection
In-line inspection processes can be automated and enhanced using a variety of conveyor modifications.
- Backlit Conveyors
A light fixture is installed inside the conveyor frame and emits light through a translucent belt.
- Provides enhanced contrast between product and conveyor belt for visual inspection and vision system interface
- Parts can be stopped directly over the lighted section or continue through uninterrupted
- Metal Free Conveyor Zone
The typical metal frame of the conveyor is replaced with a completely plastic section.
- Provides a metal free zone in the conveyor for use with metal detectors
- Parts can be stopped directly over the metal free zone or continue through uninterrupted
Multiple Belts - One Drive
When multiple lanes of product are needed, driving multiple belts or conveyors from a single drive is an energy efficient option.
- Common Driven Conveyors
Two or more conveyors can be driven from a single gearmotor using a common drive shaft or coupled shafts.
- Creates single lanes for handling parts
- Conveyors can be of different widths and lengths
- Wide parts can be carried by each conveyor to create parts access from below
- Multiple Belt Conveyors
Two or more individual belts can be mounted onto a single conveyor frame.
- Creates single lanes for handling parts
- Parts can traverse each belt to create part access from below
Accessories
A wide variety of specifically designed accessories are available to create a conveyor package that is optimum for your application.
- Chutes
Steel, Stainless and Plastic Chutes help guide parts onto or away from the conveyor belt.
- Conveyor Cover
Clear Lexan© or Stainless Steel covers can help improve operator safety and/or protect product from contamination.
