Robotunits has just released the re-engineered C5N Series of Belt Conveyors, which are now suitable for high payloads of up to 150kg per meter of conveyor. These conveyors are based on the 50mm series of Robotunits aluminium extrusions, which feature a honeycomb design and are specifically designed to handle high loads. All belt conveyors are custom made to exact customer requirements. This new series of belt conveyors are based on 55mm diameter drive and idle rollers and have been designed to offer a cost effective alternative to our heavy duty C8N range of belt conveyors. As with all other conveyors offered by Robotunits, features such as width, length, belt type and motor configuration can be individually selected by the customer. All components are kept in stock and customized C5N belt conveyors can be shipped within 3 days of customer order. All belt conveyors are serial numbered for customer convenience. Just like all other conveyors offered by Robotunits C5N units are built to CE specifications. For more information please call us on 03 9334 5182

We have just updated the labeling system to give each conveyor a unique serial number. Customers can refer to the serial number in case they need spare parts for their conveyors. All they have to do is call us and quote the unique serial number printed on the label.
Replacement parts can be shipped straight away eliminating long delays trying to figure out what is needed. We identified a need for this in the market a long time back and have implemented a serial number system a few years back. We have now updated the ID labels to also show information regarding the type of conveyor, basic measurements, and motor configuration, project number and build date. All those identifiers help us to clearly identify which replacement parts the customer is after. It is a very rare event that a conveyor breaks down but if one of our conveyors does it can mean thousands of dollars of lost production time. We therefore recommend that the main wear parts like timing belts are kept in stock and maintenance personnel has them on hand. Reordering new parts is made very easy with the new ID labeling system. It is also worth noting that each conveyor is now delivered with a printed manual which has all the operating procedures as well as maintenance schedules printed. All our conveyors are CE compliant and this fact is shown on the ID label as well as in the manual. We are trying very hard to be ahead of everyone else, making an investment in our systems a big win for our customer.
We have just released our latest addition in our already extensive conveyor lineup.

When operation any piece of machinery operators must make sure that they are run in a safe manner to make sure no harm is done to anyone. Zero workplace injuries must be the ultimate goal. Some manufacturing machinery can be automated in a way so that human interaction is not needed. In that case the machine can be completely guarded with an enclosure. The interaction between humans and the machine in general operation in this case is impossible or at least diminished and therefore a safe work environment is given.
Belt conveyors are often a piece of manufacturing machinery that cannot be guarded off completely. They are often used in a way where workers come in contact with them directly. This is one reason why belt conveyors must be designed and built to the highest relevant safety standards. Off course these safety standards are different depending on which country these conveyors are built in and to which standards they have been made. In general it can be said that developed countries have high safety standards in place where as others have none at all.
As an operator of conveyor equipment or any machinery an employer has the duty to implement them in a safe way. Local laws must be adhered to. It is important to understand that in most cases the responsibility for the safe operation of machinery lies first and foremost with the employer.
It is for this reason that it is often the best and safest way for manufacturing companies to source their belt conveyors from local companies which build their products to all the safety standards required in that area. Another alternative is to source them from a highly industrialized country with high safety standards and then make sure the conveyors meet the local requirements.
In general, belt conveyors have two areas of safety issues. The first would be around the motor and pulley drive assembly. A high quality conveyor unit will have this area completely guarded. The other area are pinch points that mostly arise around the drive and idle rollers as well as any other pinch points. This is mostly a problem area that cannot be completely eliminated. Pinch points can mostly be reduced to a minimum but remain to a certain point.
There may also be issues arising by incorporating a conveyor with other pieces of machinery. If for instance a conveyor mounts to a static sorting table then a new pinch point will arise between the conveyor and the table.
This is where a risk assessment has to be conducted by the company. Basically, all the equipment has to be studied in its current setup. Problem and safety hazards have to be eliminated and areas that cannot be eliminated totally must be minimized to a reasonable and manageable amount. Remaining risk areas have to be identified. Staff must be trained accordingly so they can safely operate the equipment.
It must be said at this point that this is a general guide and that local laws must be considered when implementing any machinery.
Manufacturing Companies trying to increase their productivity and stay competitive in the marketplace have many options available to do so. In almost all circumstances it comes down to either lowering costs for raw materials and labor used to produce a product or to increase the workflow which is the total time it takes to manufacture a product. This workflow time must also consider the material flow from goods inwards to dispatch. This is an area in which belt conveyors can make a significant difference in productivity at a low level of investment. If it can be identified that staff constantly run back and forth to retrieve certain goods then a reduction in labor costs is easily achievable in implementing a belt conveyor and run the material workflow more efficiently and thus increase productivity. Often, a strategically placed belt conveyor can have a huge impact on workflow efficiency and most likely the investment costs will be very low.
It is very important to customize these conveyors to exactly match the workflow times needed in any given manufacturing situation. An “off the shelf” conveyor system will most likely cause more problems rather than increasing efficiency. It is imperative that the conveyor system is built to take all variables into consideration. Some of those might be peak and off peak cycle times, size and weight of products to be transported, material of goods or if the system needs to be able to run in accumulation or start/stop mode.
Another very important key aspect to consider is to make sure that an even workflow is achieved throughout the entire process. If one process is running faster then another then bottlenecks are created which diminish the efficiency and mostly achieve nothing else but to move a problem from one area within the manufacturing facility to another. This is where the entire workflow process has to be taken into consideration, from goods inwards through manufacturing to dispatch. This seems quite simple but when looking closely can become quite complex. There are companies that are specialized in working out optimized workflows but for small to medium sized companies a conveyor manufacturer should have a good understanding of what is required and should be able to give some good common sense advice.
Looking at all these variables should make it very clear that belt conveyor systems must be custom designed and built to match the manufacturing environment. Saving a few investment dollars at this stage may turn out to be an expensive mistake.
Belt Conveyors are a fairly simple piece of equipment. The major components are a motorised roller, called the drive roller, an idle roller, a frame with a slider tray over which the belt can traverse and of course the belt itself. Of course there are always some other components involved but these are the main ones. In simple setups like these it is generally recommended to run the belt in one direction, which is from the idle end towards the drive roller. The Drive roller pulls the belt rather then pushing it. Running the belt in this direction allows for pretty high payloads. This is because the belt is pulled tight onto the drive roller during operation, which eliminates slippage between the drive roller and the belt and allows the full transfer of torque from the motor to the belt. This configuration also is best as far as tracking of the belt is concerned.
Is the operation of a belt conveyor in the reverse direction possible at all?
Well, it can but it can become a little tricky and some guidelines have to be considered.
If the belt is to be operated in reverse, so that the belt is pushed from the motor end towards the idler end then these points have to be considered.
- Payload weight
- Dimensions of the conveyor
- Tracking of the belt
The weight placed onto the conveyor must be kept low in this mode of operation. This is because the pushing of the belt encourages separation between the drive roller and the belt. This is reducing needed friction between drive roller and belt. The torque from the motor cannot be transferred to the belt and the result will be a slipping roller.
Dimensions of the conveyor
In general, the shorter and wider the belt, the better a push operated belt conveyor will work. This is again due to the friction that can be achieved between the drive roller and the belt. A wider roller has more surface area and allows for more friction. A long belt creates a lot of backpressure and reduces friction between drive roller and belt. There is no hard and fast rule here. The ratios of payload and dimensions of the conveyor have to be looked at as one to see if the conveyor unit will work in this given mode of operation.
Tracking of the belt
This is often an issue when running a belt conveyor in reverse. Again this is because of the potential slippage of the drive roller. If the conveyor is to be run in reverse only and payload weight is kept very low then good tracking of the belt should be easy. If the conveyor is to be run multidirectional, as in alternating in certain intervals between forward and reverse then a tracking strip is the best solution. This is simply a guide strip secured to the underside of the belt, which guarantees tracking of the belt.
At the recent NMW exhibition we displayed a number of Belt Conveyors which now occupy our limited storage area in our factory. In the past we would have dis-assembled them, re-used some common parts and basically thrown out everything else. This seems like a major waste so we thought we offer them at a greatly discounted price. If you are after a conveyor and the specifications suit your application then there is a bargain to be had.
At a 30% discount you need to be quick as this offer is on a “first come, first serve” offer!

When implementing a conveyor in your manufacturing process for transportation of goods of any kind there are many factors to consider. We here at Robotunits specialize in conveyor technology. Even more important is the fact that we also specialize in lean manufacturing principles and consider specific manufacturing situations to build a truly efficient conveyor solution for any given situation. The technical knowledge of conveyors combined with the latest lean manufacturing principles allows us to advise our customers with the absolute best solution. At the end of the day, the conveyor is just a part of the overall manufacturing process. We work hand in hand with our customers to determine all variables and provide them with solutions that make their manufacturing process more efficient. This means we look at already existing surrounding machinery and build a conveyor system accordingly.
By considering all those important steps we can truly help you to achieve a more efficient manufacturing process and increase your bottom line profit!
When implementing a conveyor in your manufacturing process you need to work out exactly what speed the conveyor needs to run at to match the current manufacturing speed. This can be either measured by looking at machines already in place or calculating proposed manufacturing cycle times. Once we know these parameters we can design the conveyor to closely match the required speeds.
By selecting different ratios within the Motor/Gearbox and also the selection of different size timing pulleys we can build the conveyor to run at a certain speed.
Of course a design like this does not allow adjustment of the speed at all, it is static. This is fine for a lot of processes were the conveyor speed is not critical. In applications were the speed of the conveyor needs to be variable a frequency inverter can be used. A frequency inverter is basically an electronic device, which changes the AC frequency to the motor and thus allowing us to adjust motor and therefore conveyor speed.
Motors are designed to work best at a certain frequency. It is therefore advisable to calculate the most likely speed required and build the conveyor with its gearbox and pulley ratios accordingly. The frequency inverter is then simply used to adjust the speed by a small amount. This is because deviations of more than 20% will result in great loss of torque and also overheat the motor.
