Application Case

The Simplest Gravity Conveyor Roller in Express Delivery/E-commerce Distribution Center


With the development of internet technology and mobile intelligent terminal, people’s lives have been very convenient. For instance, shopping online has been accepted by more and more people and has been developing rapidly. In recent five years, average growth rate of e-commerce has exceeded 20%. Over 70% packages and goods are delivered to the customers via express delivery. Therefore, global e-commerce and express delivery are building or upgrading efficient logistics distribution center.


To have better space utilization with lowest energy consumption and longest service life in modern logistics center, the design engineers in sorting and distribution center focus on how to fully use conveyor slide after goods sorting and distribution. The designers want to take full advantage of slide which is 1.8 in height,1.7 in length and the inclination angle of 19 degrees  for temporary storage of goods.


Meanwhile, the goods can slide down with gravity rather than power to save energy, lower cost and increase lifespan. Due to various types of goods of express delivery or e-commerce, different goods weight ranging from 150k to 30kg and big friction coefficient, the engineers gave up the traditional design of wooden or steel slide. At the same time, the cost of electric-powered slide is very high. Some wearing parts have to be replaced to maintain service life.


Therefore, gravity conveyor roller slide become the better choice to comply with all the requirements. However, the engineers worry about whether the small light goods like a letter weighing only 150g can slide down freely with gravity on the gravity conveyor roller with the inclination angle of 19 degrees after temporary storage and whether it has the load capacity for the heavy goods weighing 35kg as well.


Efficient space utilization with lowest energy consumption and longest service life are needed in modern logistics distribution center. The design engineers in distribution center focus on how to fully use conveyor slide after goods sorting. The designers hope to take full advantage of slide which is 1.8m in height, 1.7m in length and the inclination angle of 19°for sliding and  temporary storage of goods weighing from 150g to 30Kg. The alternative plans of slides are as follows:


Plan A. Traditional motor driven slide. The plan is relatively mature and reliable while the structure is complicated and the cost high. Regular maintenance and replacement of wearing parts is needed with high cost of operation and maintenance.


Plan B. Gravity slide that the goods slide down by the gravity. The structure is simple with low cost and maintenance -free. 


Apparently, plan B is more popular with customers. It can save much maintenance, investment and cost with eco-friendly green. However, the biggest challenge and risk is whether it is suitable for the goods like a light express envelope or a heavy box containing 24 bottles of beer to slide down on the gravity slide. The key to success is to find suitable slide material. It is impossible for the light goods as express envelope to slide down, for the sliding friction coefficient of board or steel is large. The engineers had to abandon this plan so that steel gravity conveyor roller slide is the only choice. 


Gravity conveyor roller delivered in the first project passed the tests for the lightest goods (150g) and the heaviest goods (35kg) successfully on the slide. The lightest goods can slide down easily and the heaviest have got reliable support and slide, whose performance is perfect. The customers are all satisfied with this type of gravity conveyor roller and the orders of rollers in five projects have been confirmed. After one-year operation in distribution center, over 200,000 gravity rollers have run smoothly and stably on the slide, which gives the designers great confidence. They confirmed the design that the gravity conveyor roller will be completely adopted in 50 distribution centers in the following 2 years. The total amount of roller use will surpass 2 million.


This design has saved 30% of direct cost of the single slide for the customers.’ said the project principal, ‘It’s maintenance-free and integrative cost drops by more than 50%, which has met the expected goal and been low carbon and environmental protection.


By the end of 2016, the amount of installed light gravity conveyor rollers in global express delivery and e-commerce distribution centers has exceeded over 4 million, which contributes to the rapid development of the industry.


Damon Industry roller supports corrugating industry


With the continuous upgrading of Chinese carton industry, strict environmental policy implementation and continuous increasing of labor cost, more and more carton factories are paying much attention to the necessity of intelligent carton manufacturing. Under this situation, intelligent manufacturing equipments become particularly important. It can’t harm logistics goods while guaranteeing productivity improvement. The conveyor rollers, seemingly insignificant, are the “Gene” of conveying equipment to escort the intelligent carton production. 


In corrugated industry, the conveyor rollers mainly apply to the conveying of goods like mounted paper, cardboard and carton. Damon Industry’s gravity conveyor roller is the simplest and most widely used roller, which applies to gravity or passive conveying by manpower push and pull. It is the transitional roller which applies to the equipments like die-cutting machine, splitting machine, wrapping machine and strapping machine. Damon Industry’s belt roller is the main part of belt conveyor pulleys which applies to different parts of equipment and serves different purposes such as drive, tension, direction change and adjustment. It is machine-tooled roller which applies to the equipments like laminator, stacking machine and linking machine.


Damon Industry has 40 products series of conveyor rollers that cover various specifications which apply to conveyor, stacker and storage transport line. Damon Industry’s DC24V PULSEROLLER has far-reaching influence on intelligent manufacturing development in post-print conveying and storage besides stable conveying of rollers and improvement of efficiency. It has an advantage in floor space, energy utilization, stability, and efficient conveying over the traditional conveying.


Damon Industry Rollers Provide Strong Support for the Efficient and Steady Development of Furniture Industry


With the approaching of [Industry 4.0 Era] and the increasingly growing market demand for full sets of distinctive furniture, customized furniture has become a new trend in market consumption. With the growing demand for customized furniture, the degree of automation for furniture manufacturing is becoming higher and higher.


Compared to traditional furniture manufacturing, flexible production equipment processing center will be more capable to meet the needs for customized furniture. Such equipment can be connected with automatic conveying equipment and form automatic flexible production lines. It will inevitably require the support of logistic parts which are more stable, reliable and efficient.


PVC rubber coated rollers of Damon Industry can prevent scratching and coloring to make conveying more comfortable and steady.


The surface of conveyed objects in furniture manufacturing industry is usually painted or wrapped. In the process of conveying, special attention should be paid to the avoidance of surface scratching. Rubber coating is an effective measure to prevent workpiece surface from being scratched in roller conveying process. Therefore rubber coated rollers are commonly used in furniture manufacturing industry. Although ordinary rubber coated on rollers can solve the problem of scratching, after a long time of operation, partial damage is very likely to occur when dumping dust that is adhered to the surface of the objects in convey. In addition, the rubber glue has different colors and coloring problem may occur in the process of conveying. All the problems can affect the quality of objects in convey.


Besides traditional glue roller, Damon Industry can provide PVC soft rubber glue roller solution more suitable for furniture manufacturing. With most functions of glue roller, it is similar to glue in terms of increasing friction, protecting undersurface, noise reduction and shock absorption, etc… However, its production cycle and cost performance are very favorable. The most critical point is that dusting is very difficult. Despite of slight dust falling, it will not adhere to the surface of conveyed objects. PVC is gray so it can overcome the coloring problem, a big concern of customers.

Damon Industry can supply 2mm PVC rubber coated rollers with a diameter of 50 and 60, As the most commonly used in furniture manufacturing industry, they make customers feel at ease.


Favorable circular run-out of Damon Industry enables the conveying of long objects more efficient and stable.


Circular run-out is an important performance indicator of rollers. Whether this problem is good or can directly affect the stability and reliability of material in convey. In the process of furniture manufacturing, lengthy materials often need to be conveyed so the rollers used are usually very long, mostly over 1.6m. If the circular run-out id too large, conveyed objects can jolt and deviate from normal conveying direction. It can affect the accuracy of conveying action and the noise can be louder. In addition, it can probably cause damage to conveyed objects and shorten the service life of the conveying equipment.


Damon Industry rollers are made of top-quality raw materials: including steel tubes customized strictly according to the provisions of DIN-2394 Welded And Sized Precision Steel Tubes, plastic parts made of international fist class raw materials such as Dupont , optimized chain wheel structure, special bearing for rollers of international quality, outstanding circular welding technique, extreme care and precision in every procedure. All these give rollers a good performance of circular run-out that is better than JB/T7012-2008 and secure smooth and stable conveying of lengthy objects.


In addition to stable and reliable conveyor roller series, Damon Industry can also offer one-stop solution for belt conveyor products and energy-saving DC 24V electric roller products for furniture manufacturing.


So far, roller series of Damon Industry have been widely used in furniture industry, including Sogal, Mingzhu Home Furniture and Huizhou Haolaike. It is contributing its own share of strength and value to the rapid development of this industry.


Innovative Solution of Damon Industry Micro Belt Conveyor Pulley Boost the Development of Modern Logistics


With the rapid development of modern logistics, automatic conveying equipment has been widely used in all fields;


Roller conveyor is also widely used because of its advantages of stable conveying, good embeddability, convenient maintenance, low energy consumption and long service life.


As the saying goes, „Everything has its merits and demerits.” Although the roller conveyor has its advantages, it has its application restrictions:


1.Unable to convey goods in soft package;


2.Unable to convey goods of small size;  


3.Unable to carry out uphill or downhill conveying with large angle.


4.Unable to avoid the skidding between the goods and conveying surface, especially when the speed of conveying is fast with frequent startup and shutdown.


For the above conveying occasions, we usually use belt conveyor instead of roller conveyor.But the belt conveyor also has the restrictions such as frequent maintenance,big energy consumption and the high cost.It can’t be embedded in the equipment. It is generally used in the long-distance conveying.With the development of modern logistics, especially in the modern logistics sorting center, short-distance belt conveyor is required to start and stop frequently, conveying goods efficiently and rapidly .Do we have better solutions?


For 20 years, Damon Industry team, focusing on the conveyor roller, has conducted  continuous research and test for this requirement;The technology application team brought upa bold idea, jumped out of the original roller restrictions and found innovative application solution that roller is covered with special belt — „micro belt conveyor pulley.”

Belt Conveyor Pulley of Damon Industry Help to Improve the Logistics Level of the Clothing Industry


According to statistics, China is currently the largest clothing producer and consumer in the world with the annual production of more than 40 billion pieces of clothing, which is naturally more and more demanding on the logistics level of the clothing industry. The intensified industry competition and homogenization urges the clothing industry to further optimize and improve the logistics equipment.


In the process of order sorting in the clothing industry, the unit of piece is used for sorting. Soft-bag packaging and transmission is needed. It happens that the belt conveyor is suitable for delivery; therefore, it’s of great importance that whether it can run stably and reliably in the link of delivery. However, the quality and performance of belt conveyors on the market are uneven. In terms of the use of belt rollers, cylinders and sealing plates often seal off or spindle noses and sealing plates seal off, resulting in the halt of the machine; driving devices need to be replaced to improve the driving force due to the fact that the whole-axis design structure results in the halt of the belt conveyor; the situation of intermittent belt deviation and insufficient tension occurs due to quality of raw materials of rollers and processing precision, so that the equipment shall be maintained from time to time; unmatched rollers will also cause broken axes and abnormal noise. These disturbing problems cannot be eliminated, having greatly affected the normal use of the equipment and hindered the logistics aging of the clothing industry and new trend on the clothing market, which will cause serious economic losses directly! In response to these problems, it takes Damon Industry three years to create new solutions and standards of belt rollers, striving to fundamentally solve all the problems.


The belt roller is the soul and heart of the belt conveyor. The BP-D revolving-shaft roller of German Industry is the main driving element of the belt conveyor, and this type of rollers has the following characteristics:


1. Prevent loose weld – transform the traditional welding process directly into the equipment welding (patent number ZL201520947264.8). The welding process is controlled by the equipment automatically, so that the contact surface materials between spindle noses and sealing plates and between cylinders and sealing plates are fully integrated. Strength of welding fusion of the contact surface has far exceeded the strength of the base metal itself, fundamentally putting an end to the hidden risk of loose weld!

2. Ease worn spindle noses – the professional quenching and tempering process on spindle noses makes the surface hardness of spindle noses higher, so that the wear-resistant ability under high load, tension and rotational speed has been strengthened.


3. The brand new structure – the use of new lightweight materials and design agencies has greatly reduced the weight of the shaft of the roller itself. The structure is simple and the strength is reliable, which eliminates broken shafts, reduces the burden of the driving device and makes the operation of the belt conveyor more easily and flexible at the same time.


Damon Industry also has the BP-R fixed-shaft roller, which is mainly used to increase the wrap angle of the driving roller, tighten the belt and adjust the deviation, etc., and harsher materials are used; exquisite design structure (drum-type is optional); in terms of the process, the technology of boring holes from both ends is adopted to ensure the proper alignment of internal hole processing and precision of processing and avoid the roller from moving up and down; built-in heavy-duty precise ball bearings and a series of optimization measures improve the smoothness when the roller is running and the load capacity. In addition, using with our carrier rollers with complete specifications can simplify the structure of the conveyor, reduce friction, prevent static electricity (optional), reduce noise and eliminate abnormal sound. This series of optimization and improvement of belt rollers are strong support provided to ensure the stable operation of the equipment.


At present, belt rollers of Damon Industry distinguish themselves as they are used in belt conveyors of the clothing industry, which have been applied to many projects, such as La Chapelle, Peacebird, Nike, ANTA, etc. As staff of Damon Industry, we are willing to bring the experience of other delivery industries to the clothing industry to provide strong guarantee for the delivery of the logistics equipment in the clothing industry. Damon Industry can not only supply more stable and innovative high quality roller hardware products but also provide customized roller solutions and services suitable for the application to the logistics equipment, and they are suitable for a wide range of industrial fields to help users improve operational performance and reduce overall costs.
