Roller Pitch Calculation for Sprocket Driven Rollers Chain driven live roller conveyors are used to move the products such as carton boxes, plastic crates, totes etc at a controlled speeds higher or lower whatever it may be. Chain driven live roller conveyors are beneficial because there is positive engagement between chain and chain teeth and gives excellent power transmission for heavy duty loads also. It is often a complaint that chain driven roller conveyors have more noise. But the noise comes from improper engagement of chain and sprocket. This results because of mis-calculations of roller pitch. So lets understand it. Understanding Sprocket & Chain Engagement Most of us have done chain tensioning to the cycle in their childhood. We do it, when the chain gets removed from the sprocket frequently, or their is chain noise. When you adjust the chain tensioning of the bicycle chain, you are actually managing the distance between the chain teeth, so that it engages properly. We do that by reducing the distance between two sprockets or by increasing the distance between two sprockets. This needs to be done periodically because the bolts gets loosened or chain elongates after long working. Now lets get to some basics. Any chain have pitch. If a chain is 4" chain, it means that when a sprocket moves by 1 teeth, the chain will move by 4". By the way 4" = 4inch = 4x25.4 = 101.6mm Understanding Roller Chain Calculation for pitch consideration Below are the sprocket pitches which are generally used for conveyor rollers. 3/8" = 3/8 inch = 3/8 x 25.4 = 9.52mm 1/2" = 1/2 inch = 1/2 x 25.4 = 12.7mm 5/8" = 5/8 inch = 5/8 x 25.4 = 15.87mm For Roller Conveyors, chain is transferred from one roller to other. So there is no scope for tensioning as it will disturb other pair. So how we do that. The Best way is to maintain the optimum distance while design only and there is no need to tensioning. Chain Driven Live Roller Conveyors Lets consider an example. You have to carry a carton box of 400mm length, width 350mm and weight 50kg. For any product to be stable, there has to be 4 rollers below the product any time. So 400mm / 4nos = 100mm. The pitch should be 100mm. Considering pitch 100mm, the load on each roller will be 50kg / 4nos = 12.5kg The load capacity of each roller should be 12.5kg Check the roller capacity chart. Here we take roller dia 50.8 which comes with 1/2" x 14z sprocket. The pitch of roller is 1/2inch i.e. = 12.7mm Now 12.7 x 8 = 101.6mm So ideally the pitch should be 101.6mm Roller Chain Assembly for roller conveyors If we keep that pitch 101.6mm, it will become difficult to put chain lock and join the chain. Hence to ease out the efforts, you can reduce the roller pitch and keep as 101.3 or 101 All chains come with Half Lock and full lock. so if we use half lock, we can also use odd pitches. e.g. 12.7 x 7.5 = 95.25mm. Full Lock Half lock Please refer below video where a conveyor is running at 50meters/min

Double Decker Roller Conveyor by Excel Conveyors In the intricate world of sprocket-driven conveyor rollers , the assembly of chain loops is a crucial task. Whether it's ensuring the right number of links or grappling with half lock challenges, precision is key. In this guide, we'll walk you through the process of calculating the number of chain links required for connecting two sprockets and demystify the complexities of chain assembly. Understanding the Essentials Chain Pitch and Sprocket CC: Before delving into calculations, it's essential to note that chain pitch and the center distance (CC) of sprockets are measured in metric units (mm), not inches. Familiarize yourself with the metric equivalents for common inch measurements: 06B - 3/8" = 9.5mm 08B - 1/2" = 12.7mm 10B - 5/8" = 15.87mm Chain Pitch and CC: Ensure that the values are in metric units (mm). Sprocket Pitch: Match the metric equivalent to the inch measurement. Calculating Chain Length: Sprocket Teeth: Input the number of teeth for the smaller and larger sprockets. Chain Pitch: Select the appropriate metric chain pitch based on your sprocket size. Chain Length Calculation: The calculator will determine the total number of links required for your sprocket assembly. Calculator Determining Lock Type: Calculator Result: Odd number indicates a Half Lock, while an even number signifies a Full Lock. Tips and Considerations: Precise Roller Pitch: In the realm of roller conveyors, especially when one sprocket is non-adjustable, precise roller pitch becomes imperative. This ensures optimal performance and prevents unwanted complications during operation. In Closing: Navigating the intricacies of sprocket-driven conveyor assembly requires attention to detail and a precise approach.

Load carrying capacity of conveyor rollers is crucial for the conveyor system. Under designing the system may land you in trouble damaging the system. Over designing the conveyor system might go over budgeting. Calculating load on conveyor roller is simple arithmetic and very easy. Assume that you have to design a Gravity Roller Conveyor System for carton box conveying. Weight of the carton box is 50kg Length of the box is 400mm Width of the box is 300mm Lets Calculate width of the rollers = width of the carton box + 50mm So Roller length is 350mm Now we have to decide how many rollers will be below the carton box? For a component, Box, product to be stable 3nos of rollers are required below it, assuming equal distribution of weight in the product. So 400/3 = 133mm will be roller pitch. ( Roller Pitch is always considered as Centre to Centre) . We will consider roller pitch as 100mm on a safer side. so there will be 4 rollers below the box at any time. It means 50kg weight will be distributed on 4nos of rollers. Calculating further we shall get 12.5kg Finally we need 12.5kg of load carrying capacity roller over a length of 350mm. ​In Spite of all above calculations and load Capacity Chart, one should note that above the capacities at the chart are indicative only. The load carrying capacity is dependent on lot of other factors like product weight concentricity, impact load generated on the rollers while loading the component on conveyor.

Excel Conveyors manufacturer conveyors for small business owners to large corporations. While large corporates have their teams and departments for calculating ROI - return on investments, small business owners are often confused about the term Return on Investment. Why is the word Return on investment so important? When you are running a business, your cash flow is defined. You bring the raw material, you convert them in finished goods, you sell them, you get the money, and you pay back supplier payments and salary. But when you have to purchase an asset or capital equipment, straightway that much of funds from your cash flow are locked. They are moved out of the cash flow, which is going to affect your daily working capital and so your capacity. ​​In simple layman terms, ROI is how you are going to recover your investment. There is no ROI accounting formula that will directly give you the ROI of the equipment. This is because every business is different and every business owner has own mindset to run and analyze his business. A small business owner has to make a simple accounting of what are the differences before and after the purchase of Conveyor Equipment? One has to analyze how the conveyor is going to add the difference to his/her life. When you understand this, a large amount of picture is clear for your ROI analysis.​ How do you make the decision to buy the conveyors or capital equipment for your factory automation? Will it be the right decision? What will be the cost? How to justify this cost financially? Will it be the right decision in terms of finance? What if the decision goes wrong? So it is a need to understand how to calculate the ROI of conveyor Equipment. The ROI - Return on Investment helps you to make the right decisions about buying. The payback period tells you how much time it will take to recover the investment? Let's take an example If you are looking for a packing conveyor, where you want to sort the raw material. You find a direct reduction in manpower, there will be an increment in the quantity of sorting and grading. There will be improvement in the quality of the raw material sorted. For this, you will have to maintain a record of things, e.g. how much time is required to sort for a defined quantity. How many other supporting labor are required to main sorting teams. What is the quality of sorting? How many times, the packing team have complaints about the sorting team? You can maintain such records. ​ Above is the actual scen ario. You have to mark the proposed new scenario. Number of labor required. New increased speeds of sorting. You also have to consider the increased speed of packing. Now the difference in this amount is your actual saving -- it is your profit after purchasing the conveyor. This process will also help you to generate the requirements and specifications for the conveyor. When you evaluate in deep, you will understand that whether a powered conveyor is required or a gravity roller conveyor will work? What will be the length of the conveyor needed? I may have to do trial and error so variable speed for the conveyor is needed. These specifications will help your RFQ process faster and accurate. The conveyor manufacturer can add more value, when complete information is received. Factors for calculating ROI of your Conveyor Equipment 1)Cost of the conveyor. The cost which you are paying to the supplier Transport Cost Installation & Commissioning Cost Training Cos t The buyer should inform all the possible information with the conveyor equipment supplier. Buyers should try to find out hidden costs, such as some variant or changeover parts, electrical costs, etc. If you are planning expansions in the near future the same also needs to be considered and evaluated to suit in the same equipment or capital budget. 2)Labour Cost Is there any workforce reduction due to this conveyor equipment purchase? Consider the labor cost including A)Direct wages B) Indirect Expenses such as canteen, insurance, PF etc. 3) Direct Benefits to production What are the direct benefits to manufacturing activity due to the installation of conveyors Labour productivity increases - Due to ergonomic working, productivity increases. Higher Speeds - Higher speeds will increase higher sales in turn increased profits. 4) Maintenance Cost of Conveyors What is the maintenance cost of conveyor equipments? Do I need to maintain separate manpower for it? Is it maintenance free? What is the preventive maintenance cost/year? 5) What is the Bank interest Bank interest on the funds invested. ROI = Benefits / Investment ROI - return on investment is simply the profit/investment. The higher the result higher is ROI. Higher ROI means faster recovery of the investment. Steps to calculate ROI Find out your current cost without purchasing the conveyor equipment - C1 Above mentioned costs C2 ROI = (C1-C2) / C2 = Profit / Investment Payback Period Payback period = C2/(C1-C2) (Investment/ profit ) Download here the calculator for ROI Intangible benefits Intangible benefits cannot be measured but affect the overall company performance or help to increase company brand image. Labor Supervision Cost Assume that there is labor reduction from 20nos to 10nos by purchasing conveyor equipment. If 10nos labors are reduced definitely the supervisor can have more time to do other priority work. Product Damage cost & Brand Image. If damaged products are received by customers, the brand image of the company is affected negatively. Conveyor equipment reduce the product handling and maintain the products.

Uneven loads on roller conveyors are difficult to be carried unless a roller conveyor is specially designed for that. While design of a Gravity Roller Conveyor or Powered Roller Conveyor , we use 3 or more rollers to make the product more stable. But in case of uneven loads it won't work. You have to consider that uneven loads may affect product behavior so while design of roller conveyors in India We have to support the uneven portion by 3 rollers so that it wont topple. The even portion may get stuck in the gap between the rollers. To avoid this, we have to reduce the roller pitch to minimum possible according to the size of the uneven portion. In the image below, the carton box is having concentric load at the arrow portion. This will make the box behave as shown.

Belt Tracking is often an issue faced by conveyor manufacturers and users. Maintenance people are called frequently for belt tracking problems in production areas. Below are the steps by which should be followed while tracking the belt Below you shall find the procedure to track the belt. One should understand the science behind belt untracking. Conveyor belt is cut square ( rectangle ) while joining. When the belt is trying to come to its origin, i.e. squareness it leaves its position and it gets out of the track. The elements of the belt conveyors need properly at 90degree to each other such as the support frame, the drive & driven rollers, support rollers. When we are adjusting the belt tension, we are only trying to maintain the squareness of the belt. One should follow each step carefully with the technical understanding of the same. You should provide sufficient time for the belt to take its position, after each adjustment. Do make small changes, allow the belt to move, observe the position and decide the next action. Steps to Track your Conveyor Belt and adjust tension Check runout or concentricity of the drive/driven roller Runout or concentricity of the drive/driven rollers is the most known cause of belt getting untrack. Check the drive & Driven Rollers position if it is exactly at the right angle to the belt. Basically, if you join the center lines a perfect square should be formed. Conveyor support structure may be welded or aluminum profile welded, in any case, it is necessary that it forms a perfect square. Check the Support Rollers are exactly at the right angle to the belt top.  The support rollers may force to change the position. Check if any foreign material is stuck below the belt e.g. some carton box cut pieces, metal debris, electrical wires, screws or Nuts. Check if the belt properly cut... a perfect Square Cut. If nothing above comes to your help try following 1) Check if it possible to rubberize the rollers. Rubberizing the rollers is a easy way out if it is possible. Rubber increases grip between the rollers and the belt and avoids belt movement 2) Knurling and crowning of the rollers Knurling and crowning of the rollers increases grip on the rollers and is also a good way to maintain the belt in place. Design of a belt conveyor It is always advisable to take extra care while design, so that such issues can be avoided. With the advancement technology, there are other ways to avoid and minimize the belt tracking issues. It can be avoided by following ways Coating of the Drive Roller Crowning of the Drive Roller knurling of the Drive Rollers Centre Guide for the belts.

What is Bulk conveying? Bulk conveying conveyors carry material that has a measure of Kgs/hour. Such as Wheat, cement, stones, concrete, coal This conveyor has a RUBBER belt having a thickness of 5mm or more. A three-roller frame supports the rubber belt to form a trough. This trough carries the material to be conveyed. This conveyor has a heavy-duty rigid fabricated structure. The Length of this conveyor is from meters to kilometers. You can receive more information about bulk conveying at https://en.wikipedia.org/wiki/Bulk_material_handling What is the unit handling conveyor? Unit handling conveyor carries material that has a measure of Nos/hour such as carton boxes, crates, bags, sacks. The conveyor, generally has a PVC belt of thickness 2mm and more. A flat sheet or straight rollers support this belt while carrying the units. This conveyor has a light-duty structure as well as heavy-duty depending on the application. The length of the conveyor is generally in meters. To know more about unit handling conveyors are the various options available please visit www.Econveyors.in Did you find this article useful?

Rollers are integral part of Roller Conveyors. Gravity Roller Conveyors as well as motorized roller conveyors are formed using rollers. The optimum roller selection is necessary, to avoid undue events in future. If the under capacity rollers are selected, there are chances the required life of the conveyor cannot be guaranteed. Higher capacity rollers will result in increased investment and so ROI. For this, optimum roller selection is very necessary. Roller conveyors are used for various usages such as conveying carton boxes, plastic crates, totes, drums of sizes, intermediate containers, wooden as well as metallic pallets, heavy duty automobile components and many more. Here one should note that, we are discussing about conveyor rollers of a "Roller Conveyors". Roller Conveyors are used for conveying carton boxes, components, etc. These are called unit handling conveyors. Bulk handling conveyor rollers which are used to make trough belt conveyors are in discussion here. Please read here about the difference between the two. Gravity Roller Conveyors move the product by way of gravity from higher heights to lower heights. Since no motor is used in these conveyors, there is no electric or any other consumption. They work on the basis of gravitational force. Gravity roller conveyors are the most widely used conveyors all over the world. Motorized Roller Conveyors move the product with motor. Rollers have various options to run it using power. Rollers are run with sprockets, timing pulley, o groove and poly v pulley. When controlled product speeds are required, motorized roller conveyors are used. The selection of conveyor rollers plays a major role in designing a roller conveyor. The selection of conveyor rollers depend on The weight of the component Load carrying capacity of conveyor rollers The loading and unloading conditions Speeds of the conveyor Working temperature Work environment Installation industry. Weight of the component The Weight of the component, plays important role. The weight of the component should be distributed inside the container properly. If the weight in a box is uneven, the behavior changes. In such cases, the roller pitch plays important role. Load Carrying Capacity of Conveyor Rollers What is so special about that? One has to understand that the load-carrying capacity of a roller is distributive and not concentric. If you have to carry a jumbo Bag Pallet of 1 ton weight, it does not mean that the weight capacity of each roller should be 1 ton. If the size of the pallet is 1mtr x 1mtr, the load is on the area 1sqm. The rollers which will be in the area of 1 SqM, will have load of 1 ton. This load is not on a single roller. If there are 10 rollers in this area, the load of 1ton, will be divided on 10 rollers. It also means that if a roller is having length 500mm is given load-carrying capacity as 50Kg, it implies that you can put a load on the 500mm equally and at once. It is a distributive load. If you put the weight of 50kg on any small portion of the roller say 100mm, is not allowed. it is concentric THE LOADING & UNLOADING CONDITIONS The loading and unloading conditions should equally be paid off. A metallic component of 50kg, can run on a roller conveyor. But if while loading it is dropped from a height of 50mm, the roller may be damaged . MATERIAL OF CONSTRUCTION The contact material of the rollers plays important role in selection of material of construction. Corrosive Chemicals corrode the rollers and life of the rollers is affected. Environmental Conditions such as seashore industries requires ss304 material as the humid environment reduces the life of the rollers. In some chemical industries, the normal working conditions become humid like seashore which affects the roller working. when rollers are to be used in chemical industries, the behavior of the roller material with roller material, should already be tested. WORKING TEMPRATURE Extreme conditions are always challenging. Extreme Cold or Extreme Hot conditions may affect bearing working. Do you have a different opinion? Please comment in the below section.
