RollerDrive The design ruts of RollerDrive go back to the Universal Conveyor Roller Platform 1700. All basic dimensions are the same, which enables the user to design a conveyor free of any external drives and exposed motor stations. This gives the Designer more freedom in creating flexible conveyor solutions, then using conventional AC technology. All known advantages of the Interroll Universal Conveyor Roller, like silent run thru polymer components and vibration insulation, can be also found in the RollerDrive design. The soft and hard ware design of DriveControl also supports the general flexi bility of conveyors using RollerDrive. There is a good quantity of digital I/Os to integrate RollerDrive in each new or retrofitted system. Electronic and mechanical commutated motors are the core of RollerDrive. Following ergonomically principles each RollerDrive is operating at an extraordinary low noise level. To achieve that a high sophisticated vibration decoupling of motor and gear box is used. Thus the gear box is also protected against shock loads which increases the operation time and minimizes wear. The motor is attached to a one to three stages planetary gear box, which transmits its torque via a non slip drive assembly to the tube. The RollerDrive is supported by two bearing houses sitting in the opposed end of the tube. Both are derivative from long proven Interroll standard housings. 4
RollerDrive In the conception stage of a RollerDrive application it is important to answer following points most accurate: Load Speed Cycles per minute Geometry of the box Material of the box, specifically the bottom Maximum allowable after run Existing controls to be connected to RollerDrive Environment in regards to specific protection rate Basically all RollerDrives are protected according to Industrial Protection rate IP54. However there are special versions available how exceed that and reach IP66. All bearing houses are made of electro conductive techno polymer. That prevents the typical conveyor problem of electro static charged boxes and rollers. The energy can flow easy and uncritical thru the housing and bearing to the side frame of the conveyor. It is important that the side frames all are grounded very good. 5

Technical Information for all RollerDrive Selecting the conveying speed RollerDrive is following the principle of keeping the motor speed constant and selecting the conveying speed by having different gear box reductions available. Details are described which each of the RollerDrive products. Load capacity of RollerDrive Without thru going shaft the RollerDrive is seen as roller without shaft, comparable to a flow storage roller. However there is one specific point to be noticed, the motor end is always fixed with the side frame of the conveyor. The non driven end is with the most popular version, the 11 mm hex spring loaded shaft, only a loose fit in a hex hole. That fact is compensated by having it equipped with a double bearing configuration. Thus the whole RollerDrive can be seen as roller without shaft but with fixed stub shafts. In an application it is important that in minimum always three rollers including the RollerDrive are located underneath the box. In most of the applications the torque not the load will be the minimum factor to size the unit. For detailed calculations of the maximum load in relation to the roller length, the Roller Calculation Program is ready for download on the Interroll Web Page. Using the program the shaft type must be entered as Round and the shaft location as Stub Axle. 8
Technical Information Rolling resistance and performance When a box is conveyed on a roller lane, there a the following forces to be overcome: Static friction Rolling friction A box is moving with constant speed on a conveyor, following equation is valid: F = m * g * µ F: Tangential force in Newton m: Mass in kg g: Acceleration of gravity 9,81 m/sec µ: see table below for factors related to box material Material Steel 0.03 Polymer, flat 0.04 Polymer, uneven 0.05 Wood 0.05 Carton, hard 0.06 Carton, soft 0.08 Friction coefficient Example: Load: 30 kg Box material: Techno Polymer, friction coefficient µ 0.04 Speed: 0,5 m/sec Necessary tangential force: 11.77 N At a radius of 25 mm the required torque is 0.3 Nm That leads to a mechanical performance of 3.5 Watt Table of friction coefficient The performance which is needed to convey a box at constant speed on a roller conveyor is primary determined by the shape and the material of the bottom surface of the box. Less performance is needed for a flat and hard surface, like a steel box. But steel also has the tendency to slip on the rollers which results in longer acceleration and deceleration times. A rule of thumb is about 3 % of the load is needed as tangential force for hard box material. Using carton boxes on roller conveyors needs more performance. The friction coefficient is about 8 %. The difference to steel boxes is used to deform the bottom surface when running on a roller conveyor. Thus, this energy is not available for transportation. One cycle in a conveyor consists from acceleration to constant conveying to deceleration. Due to that, for performance calculations the acceleration is a critical phase which must be determined carefully. In the acceleration phase static friction has to be overcome and is replaced by the very less rolling friction. That explains 9
Technical Information for all RollerDrive the characteristic currant peak at the beginning of each conveying cycle. Due to the complexity of each application it is recommended to consult an Interroll RollerDrive Expert and the RollerDrive Calculation Program to find out what is the right product for each application. RollerDrive Calculation Program The RollerDrive Calculation Program is part of the RollerDrive Catalogue and contains all application and performance knowledge to select the right product for each application. It also indicates the maximum number of cycles according to current and heat calculations under given load and speed. The maximum continuous currant is calculated to select the right power supply for the application. Belts, Torque Transmissions A conveyor driven by RollerDrive needs a certain type of torque transmission from roller to roller. There are several ways to accomplish that: Friction drive Round belt running in grooves or grooved drive heads PolyVee belt running in special drive heads From fit drive Tooth belt 3/8" Chain To select the right torque transmission, it is important to know the size of a box in relation to the size of the conveyor zone. If the box comes to a stop always with one RollerDrive underneath, the belts are relived strongly. In the phase of acceleration most of the start torque is directly transferred from the RollerDrive tube to the box. If there is any possibility that a box can come to a stop without having a RollerDrive directly in contact to its bottom surface, it is important to select a torque transmission which is able to transmit high start up torques properly throughout the entire life of the application. Round Belt: Applications up to 0.6 m/sec and 40 kg. It is important, that the box always comes to a stop directly on the RollerDrive. Maximum number of idler rollers is 10. 10
Technical Information PolyVee Belt: There are several advantages compared to round belts. Due to a 300 % higher ability to transmit torque, all rollers in a zone are powered very even and smooth. That helps to reduce acceleration and deceleration distances. Boxes do not slide any more over the RollerDrive due to the fact that all idler rollers are much better linked to the RollerDrive. Applications with incline and decline conveyors are optimal equipped with PolyVee belts and PVC sleeved rollers and RollerDrives. The torque is transmitted very even throughout the entire zone and the PVC sleeve increases the friction between rollers and box. PolyVee belts are flexible to accepted center to center tolerances; they also need not tension device to work in the conveyor. Conveyor with more then 15 PolyVee rollers will see a RPM-drop of about one RPM per roller. The reason for that is a transmission effect which is caused by shifting the neutral phase of the belt under load. Available versions of PolyVee belt: Flexible Type PJ; ISO 9981; DIN 7867 Pitch 2.34 mm Maximum 4 ribs per belt, 2 x 4 ribs and one groove in the hub as gap Available belt length for center to center distances: 60, 73, 94, 100, 105, 120, 133, 160 mm Basically there are two version used for conveyors: 2-rib PolyVee belt: Applications up to 2 m/sec and 50 kg. The box must not come to a stop on the RollerDrive. The belt is able to handle the start up torques. 3-rib PolyVee belt: Heavy loads, using full performance of RollerDrives. Long conveyors for straight-thru applications according to the RollerDrive Calculation program. Tooth Belt: Form fit drive, very robust but with less efficiency due to strong belt material. Center to center distance tolerance is critical for longevity of the belt. Chain: Rare used torque transmission for RollerDrive due to the fact that the chain is not maintenance-free, which contradicts the concept of a RollerDrive conveyor. 11
RollerDrive Technology Technical Data Basically there are two different types of RollerDrive, mechanical commutated BT (brush type) and electronic commutated EC. The EC RollerDrives are subdivided in regards to the location of the controller, inside (EC200 and EC300) or outside (EC100 and EC110) of the RollerDrive. All RollerDrives are differentiated by their mechanical performance which is available at the tube for conveying goods. For that the tangential force at the tube is multiplied by the speed at maximum continuous currant. Resulting performance values are the base for choosing the right RollerDrive and reflecting in relation to the electrical input performance the efficiency. 12

RollerDrive Technology Shaft executions All shaft executions are available in carbon steel zinc plated or stainless steel. Shaft executions on motor end of RollerDrive All bearing houses of the RollerDrive on the motor end are made from electro conductive Techno Polymer material. That solves the problem of static charged conveyor rollers and prevents damages to electronic components in the RollerDrive or on the conveyor. However, it is essential to ground the conveyor frame in a proper manner.

RollerDrive Technology RollerDrive Technology Protection rate of RollerDrive As a general standard, all RollerDrive are protected at the IP54 rate. By that, they are protected against dust and lower grade spray water. RollerDrive BT100 and EC200 are available in protection rate IP66. They are sealed to withstand heavy spray water and dust. All protection rates are laboratory tested and certified. Tube executions The tube of the RollerDrive is ether from zinc plated carbon steel DIN2394 or from stainless steel DIN 2463. Both versions have an outer diameter of 50 mm and a wall thickness of 1.5 mm. The maximum concentricity deviation is 0.3 mm. 21
1.8º RollerDrive Technology L Ta Non-driven roller curves The nominal dimension of the curve inside radius Ri is 800 mm for roller lengths (RL) of 300, 400, 500 mm, etc. and 850 mm for roller lengths of 250, 350, 450 mm etc. The curve inside radius is measured from the inner edge of the inside supporting profile (i.e. from the beginning of install at - ion length EL). W Ti Driven curves with RollerDrive For driven roller curves, RollerDrive has proven itself the most inexpensive and elegant solution of all well-known drive types. These curves are quiet, compact and exhibit a modern, straightforward construction. As overdimensioned components, standard O-rings are preferably used in combination with the fixed drive roller series 3500 with drive head. Due to the proj ec t - ing end of the drive head (RL=EL-36), inner curve radii of Ri 770 mm and 820 mm result. In the dimensioning of the RollerDrive, it is important to use the mean diameter of the tapered elements for calculating the required torque and the conveyor speed. The installation length should be calculated so that the conveyed items do not contact the side profiles during transport. Calculation of the minimum outer radius Ra or the minimum EL. Ra = (Ri + W) 2 + (L/2) 2 +50 EL min. = Ra-Ri 90º EL Ri Ra 22
RollerDrive Technology Adapting of the EL min. to the standard length (next larger size in 50 mm increments) 286, 336, 386 936 mm (250, 300, 350 900 mm for gravity rollers) Calculation of actual Ra with selected standard EL Ra = EL+Ri The roller pitch is generally dependent upon the properties and condition of the conveyed item and should be selected so that safe transport is ensured. In selecting the smallest possible roller pitch (Ti), the diameter of the tapered elements must be taken into account so that these do not contact each other. Otherwise, any Ti value can be selected. The only restriction to observe is that the first or last roller has a ratio to the total angle of the curve of approx. Ti/2 and that any standard belts lengths are also consided. Roller pitch Ta, measured at the inner edge of the outer profile, can be calculat ed with the following formula: Ti x Ra Ta = Ri A overview of all tapered tubes available, is located on page 56. Tube coating All RollerDrives can be sleeved with grey PVC sleeve of 2 and 5 mm wall thickness. With a hardness of 58+5 Shore (A), the friction between the boxes and the rollers is increased very positive. The sleeve fulfills the RoHS requirements. Zinc plating of tubes All carbon steel tubes are electro zinc plated and passivated according to DIN 2394. The coating thickness is between 8 and 15 µm. All materials for the zinc plating process are according to RoHS requirements. The zinc plated and passivated tube surface is sensitive to scratching and rubbing loads. White rust will be a result of damaged passivation and shows the selective destruction of the protection system. However, there is no derogation to the function of the RollerDrive. Larger temperature deviations should also be avoided, they can cause cracks in the passivation, which will result also in white rust. However, the protection system zinc plating and passivation for carbon steel tubes, is an adequate and proven method which gives cost optimal corrosion protection for RollerDrive. For applications in harbors or near to the sea in salty environment, also in tropical areas or for the transport of wet goods it is recommended to use stainless steel tubes and shafts for RollerDrive. 23
RollerDrive BT100 Basic information With a mechanical performance of 11 Watt and a mechanical commutated motor the RollerDrive BT100 is the optimal solution for application with lower throughputs and less weight.
