Material Handling Systems for Robotics and Automation

What Are Material Handling Systems Used For?

In robot automation, parts must reach the right place at the right time. Depending on the application, they may also need to be separated, turned into the correct position, or made easy for a robot to pick.

A material feeding system can therefore perform one or more of these tasks:

• Move parts from one station to another

• Store a supply of loose parts

• Deliver parts one at a time

• Turn parts into a fixed orientation

• Present parts inside a robot pickup area

• Sort different parts

• Connect several machines or workstations

The right system depends mainly on the condition of the parts and how they need to arrive at the robot.

Which Type of Material Handling System Do You Need?

The product types available on RBTX solve different tasks.

A conveyor belt only transports the part. A feeding system prepares it for the next step. This preparation may include storing, separating, orienting, or positioning the component.

When Is a Conveyor Belt the Right Choice?

A conveyor belt is suitable when parts mainly need to move from one place to another.

Common applications include:

• Moving finished parts out of a machine

• Supplying a robot with trays or containers

• Connecting two production stations

• Moving products through an inspection area

• Removing rejected parts

• Transporting components to a packaging station

A conveyor is often the simplest type of conveyor automation. It is especially useful when the part is already organized or when the robot can pick it without a fixed orientation.

Before selecting a conveyor, clarify the required belt length, width, speed, load, and transfer height. Also check whether side guides, sensors, a frame, or a controller are included.

A conveyor alone may not be enough when loose parts must be separated or aligned before the robot can pick them.

When Is a Hopper Feeder Useful?

A hopper feeder stores a larger quantity of loose parts and releases them gradually.

It is often used before a bowl feeder, vibratory feeder, or flexible feeding system. Its main purpose is to reduce manual refilling and keep the following feeder supplied.

A hopper feeder is useful when:

• The robot needs a steady supply of parts

• An operator should not refill the system every few minutes

• Loose parts are delivered in boxes or bins

• The next feeder should receive a controlled quantity

• Longer periods of automated operation are required

The hopper should match the size, weight, and sensitivity of the parts. A very large hopper is not always better. Heavy or delicate parts may be damaged when too many components are stacked together.

When Do Parts Need to Be Separated?

Loose parts often arrive mixed together in a container. Before a robot or machine can process them, they may need to be delivered one at a time.

A component separator or vibratory feeder can perform this task.

This type of system is useful for:

• Small plastic components

• Metal parts

• Assembly components

• Fasteners

• Caps, clips, or inserts

• Parts that must reach the next process individually

The correct solution depends on how the parts behave when they touch each other. Long or curved parts may become tangled. Very light parts may jump during vibration. Oily or sticky parts may not move evenly.

For difficult components, a test with real production parts is often more useful than selecting a feeder from dimensions alone.

When Is a Bowl Feeder the Right Choice?

A bowl feeder sorts loose parts and delivers them in a defined orientation.

It is especially suitable when the same part is processed repeatedly and always needs to arrive in the same position.

Typical applications include:

• Assembly of small components

• Inserting parts into a machine

• Supplying clips, caps, or connectors

• Feeding parts for pressing or joining

• Automated screw or fastening processes

A bowl feeder is normally designed around a specific part. This can provide reliable and fast feeding, but it also limits flexibility.

When the part geometry changes, the bowl may require modification or replacement. A bowl feeder is therefore most useful for stable production with only a few product variants.

When Is a Flexible Feeder Better?

A flexible feeder does not force every part into one fixed mechanical path. Instead, it spreads the parts across a surface. A camera finds a suitable part and sends its position to the robot.

This is useful when:

• Several different parts are processed

• Product changeovers happen frequently

• Production batches are smaller

• Parts may arrive in different orientations

• Mechanical sorting would be difficult

• The robot already uses a vision system

Flexible feeding is often easier to adapt to new products than a dedicated bowl feeder. The change may be handled through software, a camera recipe, or a different robot program.

However, flexible does not mean universal. The feeder surface, camera, robot, and gripper still need to match the part.

When Is a Complete Sorting Station Useful?

A complete robotic sorting station combines several functions in one system.

Depending on the design, it may include:

• Part storage

• Feeding equipment

• Machine vision

• Robot

• Gripper

• Controller

• Safety equipment

• Frame or enclosure

The QKM Tobot FlexSorter products available on RBTX belong to this type of solution.

A complete station is useful when feeding, detecting, sorting, and robot handling should be purchased as one coordinated setup. It can reduce the need to select and combine every component separately.

A complete station costs more than an individual conveyor or feeder because it includes more functions. The correct comparison is therefore not the product price alone, but the amount of additional equipment and engineering still required.

Which System Fits Which Application?

Which Part Information Is Important?

The selected system must match the actual part.

Before purchasing, collect the following information:

• Part length, width, and height

• Part weight

• Material

• Surface

• Shape

• Number of variants

• Required orientation

• Required number of parts per minute

It is also important to describe how the parts behave in a container.

Do they become tangled? Can they roll? Are they easily scratched? Do they stick together? Are they flexible or unstable?

These details can determine whether a belt conveyor, bowl feeder, vibration plate, or flexible feeder is suitable.

How Many Parts Must the System Supply?

The feeding rate should match the robot or machine cycle.

For example, when a robot needs one part every five seconds, the system must reliably provide at least that amount. A feeder that occasionally delivers many parts but frequently stops may still cause robot waiting time.

The required output should therefore be based on normal production conditions, not only on the maximum technical speed.

Also consider:

• Short interruptions

• Product changeovers

• Rejected parts

• Refilling time

• Parts that are difficult to separate

A small buffer can help maintain a stable supply. A hopper can reduce the number of manual refills.

Does the System Need Machine Vision?

A camera is useful when the robot must determine the exact position or orientation of the part.

Machine vision is commonly used with flexible feeders and sorting stations. It can also identify different part types or check a component before the robot picks it.

A camera may not be necessary when a bowl feeder delivers every part in the same position. In that case, a simple sensor may be enough to confirm that a part is ready.

Before purchasing, clarify whether the system needs to:

• Detect that a part is present

• Calculate a robot pick position

• Identify different parts

• Check part quality

• Read a code or marking

Also check whether the camera, lighting, software, and robot connection are included.

How Does the System Connect to the Robot?

The feeding system and robot must exchange basic information.

A simple conveyor may only need signals for start, stop, and part available. A flexible feeder may also send part coordinates, product recipes, and fault messages.

Before selecting a product, check whether it can communicate with the robot controller or PLC used in the application.

Also clarify whether a controller is included or whether an additional control unit is required.

What Is Included in the Product?

Products with similar names may include very different components.

A lower-priced product may require additional controls, sensors, framing, or programming. A more complete system may therefore be easier and less expensive to integrate overall.

What Do Material Handling Systems Cost?

The cost depends mainly on what the system must do.

A simple conveyor only moves parts. A bowl feeder also separates and orients them. A flexible feeder adds camera-based position detection. A complete robotic station may include feeding, vision, robot handling, and controls.

The best purchase decision should consider the complete setup, not only the price shown for the main product.

How to Choose the Right Material Handling System

Start by answering five questions:

1. What should happen to the part: transport, storage, separation, orientation, or sorting?

2. How should the part arrive at the robot?

3. How many different parts will be processed?

4. How many parts are needed per minute?

5. Which components are already included in the system?

The answers normally lead to one of these choices:

Frequently Asked Questions About Material Handling Systems

What Are Material Handling Systems?

Material handling systems move, store, separate, orient, or present parts for industrial processes.

When Is a Conveyor Belt Sufficient?

A conveyor belt is usually sufficient when parts only need to move and do not require a fixed orientation.

When Is a Bowl Feeder Useful?

A bowl feeder is useful when the same small part must repeatedly arrive in one defined position.

When Is a Flexible Feeder Better?

A flexible feeder is often better for several part variants, frequent changeovers, or camera-guided robot picking.

Does Every Robot Feeding System Need a Camera?

No. A camera is mainly required when the robot must detect position, orientation, type, or quality.

Can One System Process Several Part Types?

Flexible feeding systems are generally better suited to several part types. Dedicated bowl feeders are usually designed for one main component.

Which Information Is Needed Before Purchasing?

You need the part dimensions, weight, material, required orientation, number of variants, required output, available space, and information about the robot or PLC connection.
