1 UPGRADE PLASTIC TOP CHAIN WT2515/TTUPM-H PLASTIC TOP CHAIN TM

2 TM Wide Type Now Available Bevedolphin Beverage + Dolphin Bevedolphin is the name of Tsubaki s new plastic chain series for the beverage industry. Bevedolphin quickly and smoothly conveys your beverage containers, just like a dolphin quickly and smoothly swims through the sea. At Tsubaki, we believe Bevedolphin chains are perfect for the beverage industry. The line-up has been newly expanded with the addition of the WT2515(G)-W wide-type plastic modular chain series. This series is ideal for conveying beverage bottles. WT2515-W Type Easy maintenance with plugs that prevent pins from falling out WT2515G-W Type Tab guide attachment type is also available NEW NEW TTUPM-H Type Prevents chain floating on curved sections when used in combination with magnet-embedded rails WT2515G-M Type Plug-less structure prevents pins from falling out 1 TM is pending trademark in Japan, U.S.A., Europe, Singapore, Australia, India, Indonesia, Philippines, Thailand, Vietnam, Korea, Taiwan, and China.

3 Bevedolphin Features WT2515-W Type, WT2515G-W Type Easy Maintenance Plug WT2515-W chain features a 25.4 mm pitch and or 170 mm-wide modular links. Plugs prevent pins from falling out. It s easy to connect/ disconnect chains to minimize maintenance time. A tab guide attachment type is also available. Plastic pin Plug TTUPM-H Type Special Double-Layer D-Type Plastic Pin TTUPM-H Type uses the world s first special double-layer D-type plastic pin combining both plastic and metal. It possesses all the features of plastic while preventing floating through magnetism. (Outside: Special engineering plastic [white]) (Core: metal) Special engineering plastic Curved rail Special double-layer D-type plastic pin Metal Note: When connecting or disconnecting the chain, use punches with a 6 to 7.5 mm diameter. Smaller punch diameters may knock out the core metal pins. NEP (Neptune) refers to a highly corrosion-resistant coating developed originally by Tsubaki. Magnet embedded in curved rail Special double-layer D-type plastic pin Combination of links and pins Combination of rail and chain Longer Service Life When exposed to water, all-metal pins tend to suffer wear that leads to significant elongation. To minimize wear elongation and prolong the life of the chain, our special double-layer D-type plastic pins use special engineering plastic at the points where they slide against the links. Test Conditions Comparison The graph on the right shows our in-house test results. 1 Special double-layer D-type plastic pins (new Tsubaki TTUPM-H type) 2 All-metal pins (competitor equivalent): Chain speed 60 m/min; Ambient temperature; 5 kg weight load; Contact with water (water drip) Wear Elongation Wear Elongation Comparison Graph All-metal pins (competitor equivalent) Special double-layer D-type plastic pins (TTUPM-H type) Test Time Significantly Lighter Pins Special double-layer D-type plastic pins are much lighter than conventional pins. Being 15% lighter than all-metal pins, they can reduce capacitance and reduce to optimal levels the chain s attraction to magnet-embedded rails in curved sections. Test Conditions Comparison 1 Special double-layer D-type plastic pins (new Tsubaki TTUPM-H type) 2 All-metal pins (competitor equivalent) Chain speed: 60 m/min; Ambient temperature; 5 kg weight load Test conveyor: Approx. 2,600 mm; One curved section Reduces Chain Weight Reduces Required Power Weight comparison with all-metal pin chains as Comparison of required power with all-metal pins as Lighter weight 15% reduction 0 1 TTUPM-H type (special double-layer D-type plastic pins) 2 Competitor equivalent (all-metal pins) Lighter weight and optimized magnetic strength reduce required power Reduces required power 15% reduction 1 TTUPM-H type (special double-layer D-type plastic pins) 2 Competitor equivalent (all-metal pins) 2

4 WT2515G-M Type Special Stepped Plastic Pins Base link (plastic) WT2515G-M uses special stepped plastic connecting pins. With plug-type connecting pins (which use plugs to prevent pin fall-out), there s a risk of foreign matter entering when plugs fall out. By contrast, there s no such risk with our special stepped plastic pins, as they incorporate a structure to prevent pins from falling out. Comprising only links and pins, the simple structure is also easy to handle. Special stepped plastic pin (special engineering plastic) Combining WT2515 and TTUPM-H Types Can Be Installed on Same Structural Frame The straight WT2515G-M type and the curved TTUPM838H type can both be installed on the same structural frame, so designing a multi-row conveyor is easy. The WT2515(G)-W type can also be set up in parallel. See below for an installation example. WT2515-W type WT2515G-M type TTUPM-H type WT2515-W type WT2515G-M type TTUPM-H type WT2515G-M type sprocket (No. of teeth: 18T) TTUPM-H type sprocket (No. of teeth: 16T) Same shaft for straight and side-flexing lanes Specifications (Plastic Materials) 3 ALF Advanced Low Friction Series Advanced low friction polyacetal chain links 1. Protects conveyed items A special material incorporating a silicone-based lubricant significantly lowers the coefficient of friction by 15% to 30% compared to that of LF Series (under dry conditions). Line pressure is reduced during accumulation, minimizing potential scratching or other damage to conveyed items. 2. Smooth divergence and accumulation of conveyed items 3. Less required drive power Applications Ideal for conveying PET bottles and paper packs Ideal for use in accumulation areas just before casers and inspection equipment Ideal for combiners Ideal for reducing or eliminating lubricants (soapy water, etc.) When better slipperiness than the LF Series is desired HG Low Friction Wear Resistant Series Low friction wear resistant polyacetal chain links ALF (color: light blue) Coefficient of Dynamic Friction Down 15% to 30% ALF LF Standard HG (color: navy blue) Countermeasure against Wear Powder The wear resistance of the HG series is improved by 20% compared with our LF series. The LF series can be replaced with the HG series without the need for conveyor modification or sprockets. When replacing the chain, we recommend also replacing the wearstrips, preferably with PLF or PMW wearstrips. Applications Processes where lubricants cannot be used: Caser lines Single-row conveyors with fast chain speed: Inspection lines, printing lines, single filers, etc. Dry lubrication processes: Inspection lines just before caser lines Comparison with Other Brands The following graph shows in-house test results. % Elongation approx. 2.5 times Company B Tsubaki ALF series Hour ALF series Company B Comparison of Elongation The Tsubaki ALF series promises a service life around 2.5 times longer than that of company B s comparable product.

The abrasion volume loss of Tsubaki LF series chain is represented as. Chain speed: 60 m/min; At ambient temperature, without lubrication Note: Company A: New anti-wear chain from Company A; polyester links Company B: New anti-wear chain from Company B; polyacetal links % Anti-wear approx. 40% Rail Chain Tsubaki ALF series Rail wear Chain wear Overall wear Rail Chain Company B ALF series Company B Chain and Rail Wear Volume Comparison Compared with company B s product, the Tsubaki ALF series offers around 40% reduced wear. Note: ALF series plastic chains and PLF series plastic rails contain silicone-based lubricant. They should therefore not be used for printing processes or in situations where silicone would have a harmful effect. When replacing existing chains with ALF series chains, we also recommend replacing the rails. When using the ALF series, please use Tsubaki high-rotation return rollers or return rollers with a 60 mm outside diameter (i.e., a high inner/outer diameter ratio). Protects Conveyed Products The coefficient of dynamic friction is the same as the LF series and 15% 45% lower than the Standard series. The HG series can minimize line pressure during accumulation and prevents scratches to conveyed products HG chain LF chain Company A Company B

11 1. Selection Precautions for Selection Plastic Top Chains are not recommended for use in operating conditions where they may be subject to impact or catch foreign material as this may damage or break the chains. Consider using a metal chain. Also, use inverter control, etc. to slowly start and stop the conveyor. Plastic Top Chains may suffer premature wear when used in operating conditions where they may contact abrasive material. Consider using a metal chain. Contact a Tsubaki representative before using Plastic Top Chains in contact with special liquids (acidic or alkaline chemicals or solutions) or in special environments (UV rays, etc.). The operating temperature range for accessories, sprockets, and idler wheels made of UHMW-PE (ultra-high molecular weight polyethylene) is 20 C to 60 C. Also, do not use in contact with steam. Toxic gases may be generated if Chemical Resistant Series (including Super Chemical Resistant Series) chains are exposed directly to open flame or temperatures above 150 C. Do not expose these series to excessive heat or open flame. Plastic chains are flammable. Do not use above the maximum allowable temperature or near open flame, as they may catch fire and generate dangerous toxic gases. Corrosion Resistance against Different Liquids When selecting a chain, refer to Table 1 to check whether the material is appropriate for the intended application. You can also use this corrosion resistance data to check the material of the rail used with the Top Chain. The table shows results obtained in a laboratory at 20 C and does not guarantee usability in all conditions. Consider the overall operating conditions (including humidity) with actual use. The table shows the material of the constituent components used in the top plates and chain individually, so be sure to check them the material in combination. Reagents with no concentration indicated are saturated or a % solution. Use caution when mixing solutions as their conditions differ. Table 1.

Determine Chain Size and Width WT2515(G)-W 1) The maximum tension applied to the chain (F) derived using formula (1) is converted into chain tension per one meter of chain width by the following formula. 0F Chain width (mm) (2) 2) A chain can be used when the tension per one meter of chain width (F ) that is obtained using formula (2) is below a curve representing the maximum allowable load of the chain that takes into account chain speed and temperature. If the tension, thus obtained, is found to be within the allowable range, determine the size and width of the chain. 1.

The amount of slack in the chain between return rollers should be 50 to mm. Using different intervals or amounts of slack may result in chain skipping. 2) Return roller intervals Place the return rollers at even intervals after the first return roller just after the drive. (Recommended roller interval is about 400 to 600) 3) Engagement angle The engagement angle between the drive sprocket and the chain must be greater than ) Height of wearstrip on carry way (H) See figure below. 1.

Amount of Chain Slack Table 1 shows the spacing L between return rollers supporting the chain on the return way below the drive sprocket. The amount of slack in the chain between return rollers should be 50 to mm. This slack prevents chain teeth jumping. There is a possibility of chain teeth jumping if the amount of slack is outside this range. 2. Engagement Angle The engagement angle of the chain on the drive sprocket should be at least 180. If the angle is small, teeth jumping may occur. Design for Return-Way Curved Wearstrip Position return rollers or sliding shoe under both ends of the curved wearstrip to guide the chain. Location of the return rollers should be 50 to 150 mm away from the base. Cross-section of conveyor Carry-way curved wearstrip Wearstrip 3.

Conveyor Layout There are two methods of supporting the return way: the return roller system, and the wearstrip system. Examples are shown below. Precautions: The infeed section of the return wearstrip should be made with a large radius of at least R40. Cut the chain so that the catenary section will have an appropriate amount of slack to compensate for expansion and contraction caused by temperature changes.

17 Handling Sprockets In general, square shafts are recommended for the drive and driven shafts used with plastic modular chain, except for fixedwidth chains. Because changes in temperature will cause the chain to expand and contract, sprockets must be mounted so that they are free to move laterally across the width. However, to prevent meandering (snaking) of the chain, one (or two) sprocket(s) should be locked in position in the center of both the drive and driven shafts using setscrews or set-collars and hexagonal socket head cap screws. When installing the sprockets on the square shaft, the inscribed markings or identification marks should be used to orient the sprockets so that they all face the same direction and to keep the position of the teeth aligned. Locking Sprockets The sprockets and the shaft are loosely fitted in order to absorb differences in thermal expansion between the chain and the conveyor and also installation errors of the chain and the sprockets. However, a setscrew, a hexagonal socket head cap screw, or a set-collar should be mounted on each side of a sprocket installed around the center with about 0.5 mm (1.6 mm for WT) clearance with the sprocket in order to prevent winding motion in the chain mm for WT Phase Matching of Sprockets Install the sprockets on the shaft in such a manner that the direction and the position of all the inscribed markings or identification marks on the sprockets are aligned. Split sprocket Identification mark Setscrew, Sprocket installed around hexagonal socket center of shaft head cap screw, set-collar Note: Fix the sprocket to be installed between the tab guide attachments when using a chain equipped with tab guide attachments. Chain Installation Wind the chain onto the sprockets installed at the given intervals If the sprockets are installed at the wrong interval, the chain may run over the sprocket and break. Make certain of the center distance between the sprockets. Chain Expansion/Contraction Plastic modular chain is made of polymer resin and will expand and contract with changes in temperature. A rough estimate for linear chain expansion is (/ C) using 20 C as the reference temperature. The expansion per nominal width ( W) is found using the following formula: W =chain nominal width (operating ambient temperature-20) (Example) For K60 chain (1,524mm wide) used in an environment where the temperature rises from 20 C to 60 C: W=1524 (60-20) =9.1mm 16

18 4. Assembly and Disassembly of the Chain Assembly and Disassembly of TTUPM838H The D-pin type connecting pins can be inserted/removed from either side. Use a punch with an outer diameter of 6 to 7.5 mm. Ensure that the pins are fully but not excessively inserted. Punch (ø6 to 7.5) Punch (ø6 to 7.5) Re-assembly Do not reuse a previously inserted connecting pin (special stepped plastic pin [orange] ) to connect chains. Connecting pin (special stepped plastic pin) Use the dedicated connecting pin (special stepped plastic pin) to assemble the chain. The special stepped plastic pins are colored orange so they can be distinguished from the base chain pins (white). One connecting pin is provided for each chain. Note: Do not use a punch with an outer diameter smaller than 6 mm or greater than 7.5 mm as they may damage the chain and/or pin. Assembly and Disassembly of WT2515G-M330 Disassembly Apply the punch (with max. diameter of 4.5 mm) to the side of the pin without a cutout, and punch out the pin by tapping the punch with a hammer. With cutout Without cutout Side with cutout Cutout Side without cutout Punch (max. ø4.5) Assembly and Disassembly of WT2515(G)-W Disconnecting WT2515(G)-W 1) Insert a small flathead screwdriver or similar tool between the chain and the plugclip on the side of the chain. 2) Using the screwdriver as a lever, pry out and remove the plugclip from the base chain. Work carefully so that the plug-clip does not pop out and fly off. 3) Use a threaded head screwdriver and screw it into the center hole (1.0 mm dia.) of the pin and pull out the pin to disconnect the chain. Note: Pins need to be removed from the correct direction. Assembly Use the dedicated connecting pins (special stepped plastic pin [orange]). Insert the pin from the side without cutout into the link. Connect the chain by applying a punch to the side with cutout and tapping the pin into the link. Pins can be inserted from either side of the link. Punch (max. ø4.5) Protrusion Cutout Reconnecting WT2515(G)-W 1) When reconnecting the links of a chain, bring the ends of the two chains together, interlace the links, and insert the connecting pin from one side. 2) Then re-insert the plug-clip to cover the insertion area. At this point, check the orientation of the plug-clip (make sure that the protrusion is going into the pin hole), and seat the plug-clip by pushing in until you hear it click into place. 3) Check that the plug-clip is properly installed. 17

19 For Your Safety When Using the Chain Warning To avoid danger, observe the following rules. General Do not use chain or chain accessories for any purpose other than their originally intended use. Never perform additional work on chain (including machining, grinding, annealing, cleaning with acids or alkalis, electroplating, or welding or cutting with a torch which will cause heat effects). These processes may cause the chain to break during operation, leading to a risk of severe injury. When replacing a worn or damaged part, do not replace just the worn or damaged part. Replace all parts with new parts. The chain may break during operation, leading to a risk of severe injury. When using chain in a lifting device, set up a safety barrier and do not allow anyone to go under the equipment. Also, when jigs or tools are connected to the edges of the chain, be sure to adequately lubricate the connecting parts. Detachment of the chain or unexpected chain breakage may lead to severe injury from flying or falling parts. Strictly observe the general guidelines listed in Section 1, Chapter 1, 2nd Edition of the Japanese Occupational Safety and Health Regulations as well as rules and regulations concerning occupational safety and health in your region/country. Always install safety equipment (safety covers, etc.) on chain and sprockets. There is a risk of severe injury from conveyed items or the chain as a result of becoming caught in the chain or from unexpected chain breakage. Chain and sprockets must be inspected on a regular basis. Damaged parts, or parts that have reached the end of their service life, should be replaced with new parts. There is a risk not only of the chain not functioning properly, but also of severe injury from chain breakage or abnormal operation. Perform the work as instructed in the manual, catalog or other documentation that was provided with the product. During Installation Before starting work, turn off the power switch and take measures to prevent it from being turned on accidentally. There is a risk of severe injury from becoming caught in the chain. Always wear safety goggles when using hammers while working to connect chains. There is a risk of severe injury from flying metal fragments or splinters. Secure the chain and parts to prevent them from moving freely. There is a risk of severe injury from chain components moving under their own weight, or from falling and body parts becoming pinched in the chain. If using chain for people conveyors (moving walkways), install protective equipment on the conveyor for safety. There is a risk of bodily injury or damage to the conveyor if the conveyor runs out of control. Caution To prevent accidents, observe the following rules. Understand the structure and specifications of the chain that you are handling. Before installing chain, inspect it to make sure no damage occurred during delivery. Inspect and maintain chain and sprockets at regular intervals. Chain strength varies by manufacturer. Only Tsubaki products should be used when chain is selected using Tsubaki catalogs. Start and stop the chain gradually, and do not subject it to sudden impact. Do not apply initial tension to the chain. Consult with a Tsubaki representative before using the chain in cases where it will be in contact with special liquids or used under special environments. When using chains with engineering plastic pins under wet conditions, make sure that the temperature does not exceed 60 C. The link material for ALF ultra low friction series contains silicone-based lubricant. Therefore, do not use this chain for printing processes, or in cases where silicone will have a harmful effect. Using a plastic top chain in a wet environment will decrease the resin s self-lubricating ability and thus shorten the life of the chain. The operating temperature range for accessories, sprockets, and idler wheels made of UHMW-PE (ultra-high molecular weight polyethylene) is 20 C to 60 C. Also, do not use in environments where such components will be exposed to steam. Plastic chain is flammable. Do not use at temperatures above the maximum allowable temperature or use near open flame. Combustion may generate dangerous toxic gases. Warranty 1.
