Edge bander return conveyor

Types of Edge Bander Return Conveyors

An edge bander return conveyor is an important part of an edge banding machine. The purpose of the return conveyor is to bring back the workpiece after it has been processed by the edge-banding machine. This allows for continuous feeding of workpieces into the machine with minimal delays. The return conveyor is typically located at the opposite end of the input section. Below are some types of edge bander return conveyors.

• Rollers: Roller conveyors are the most popular type of return conveyor system for edge banding machines. They consist of a series of rollers placed parallel to each other over a frame. The rollers are free to spin, and an pushed by gravity to return the workpiece back after the edging has been done. Roller conveyors can be operated manually or automatically. Apart from serving as an edge bander return conveyor, roller conveyors are commonly used to transport packages and boxes in warehouses.
• V-Guides: V-Guides are another type of edge band return mechanism. They make use of a V-shaped channel to guide/ sofa the workpiece as it returns. The V-Guide is usually mounted on a flat surface, and the V-Shape helps to center the workpiece as it returns. This prevents misalignment and ensures that the workpiece is properly positioned for further processing or operation. One good thing about V-Guides is that they take up very little space compared to roller conveyors.
• Nets/ Belts: A belt or network return conveyor system moves the workpiece back by means of a small belt or network. They are powered by a motor that rotates and moves the workpiece to the designated position. This type of return mechanism is unique because it can be used to edge band workpieces of varying lengths. Furthermore, belted/ netted edge return conveyors are very ideal when dealing with delicate or fragile workpieces.
• Air Float: An air float return conveyor system utilizes pressurized air to ‘float’ the workpiece as it returns. This method works excellently in setting where high-speed processing is required. Air floats are very useful when dealing with large-scale edge banding operations.

• Check and maintenance of the drive system: Inspect the motor, reduction gears, and chains to ensure they are operating well. Lubricate and clean the drive system components as needed, and check for any loose or damaged parts to ensure stable operation.
• Inspection and maintenance of pneumatic systems: Check the pressure, valves, and cylinders of the pneumatic system to ensure proper operation. Clean and maintain the pneumatic system components as needed to avoid malfunctions.
• Regular overall inspection: Regularly inspect the entire edge banding return conveyor, including fasteners, adjustment mechanisms, etc. Ensure all parts are securely fastened and operating properly, making necessary adjustments and repairs as needed.

Scenarios of edge bander return conveyors

Return conveyors for edge banders are essential pieces of equipment in many woodworking industries, particularly those that manufacture products requiring board edges. Below are some scenarios typical of how edge bander return conveyors are used.

In large furniture-making companies, batches of furniture pieces are constantly being churned out. Such companies often use automatic edge banders with return belts to allow for continuous feeding. This also ensures that banded pieces are consistently delivered to the next stage of the process, which could either be an edging finishing stage or packaging.

Cabinet-making companies also frequently use edge bander return belts. They are efficient in assisting with the processing of numerous cabinet pieces. Without having to manually assist each board, automated edge banders with return belts make it simple to edge all the exposed areas of the board.

Return conveyors are useful for training schools that focus on woodworking machinery and carpentry. Such institutes typically have a lot of students to teach and limited time. An edge bander is safer and easier to use when its returning conveyor is present because students do not have to manually position the boards.

Small to medium-sized woodshops can also benefit from an edge banding machine with a return conveyor. Although they may produce lower volumes than large-scale workshops, their consistent output requires efficient processing methods. The return conveyor helps to maximize floor space, which is a precious commodity in smaller shops.

How to Choose Edge Bander Return Conveyors

When choosing edge bander return conveyors, these three critical factors should be prioritized: quality, adaptability, and automation of the edge band return conveyor.

Quality is, of course, an essential factor to consider when purchasing any machinery. In terms of quality, one should ensure that the materials used for the edge band return conveyor are sturdy and can withstand constant use without needing frequent repairs. Additionally, a well-constructed and properly maintained return conveyor will often run smoothly and quietly, allowing for more effortless edge banding and less distraction for staff.

The ability to adapt the machine to fit existing work areas is another important factor when considering an edge band return conveyor system. Various models are available to suit different workshop layouts, such as modular designs that integrate with other conveyors seamlessly or compact versions with a small footprint that can be placed in tight spaces. For instance, curvilinear conveyors allow the return line spacing to be reduced considerably, to around 0.2-0.5m, which is just a small fraction of the straight-line conveyors. Therefore, such a machine can be easily accommodated in a workshop focused on space.

Another important feature that buyers look for when purchasing an edge band return conveyor system is the automation.

A banding return conveyor machine that is automatic will reduce the number of people needed to operate it, thus lowering labor costs. Automatic conveyors can also move items to and from machines faster than manual labor, helping to streamline manufacturing processes and improve productivity. This will be especially important in industries with high production demands and tight deadlines. In addition, a sensor that has the edge banding machine can help stop and start the conveyor automatically, minimizing the need for manual input while ensuring that work flows seamlessly through the workshop.

Edge bander return conveyor Q&A

Q1: What is the difference between a roller return and a belt return on an edge bander?

A1: The return path for the workpiece can be made as a set of rollers or a belt. The roller return typically has less surface area and is manufactured from steel, which may not have any coating. This can be a low-friction option but may not be suitable for all types of workpieces. A belt return provides more surface contact and is usually covered with some sort of flexible plastic or rubber to prevent any damage to the workpiece.

Q2: Does the edge band return conveyor require any electricity?

A2: Depending on whether it is a roller or a belt return, the amount of electrical power will differ. Rollers usually do not have any electrical components, so they are considered passive. Edge banding conveyors with belts are active and may require a small step-down transformer to convert the required voltage.

Q3: How is the edge band return conveyor connected to the main machine?

A3: The edge band return conveyor is usually connected with a couple of bolts or clamps to the main machine. It is aligned, so the edge banding of the workpiece flows seamlessly from the machine to the returning conveyor. Some advanced designs may have height adjustments and quick-release clamps for faster setups.

Q4: What are the latest trends in edge band return conveyors?

A4: Some exciting developments in edge band conveyors are automatic height adjustment via servos, speed variation of belts and rollers, smart sensors for logging and tracking workpieces, and logging data in the cloud. Compatibility with a variety of machines and conveyor speeds makes it easy to integrate this return conveyor into any existing setup.
