5 Safety Function of the Conveyor: Transnorm belt conveyor system TS may only be used to convey unit loads within a conveyor system and is not designed for bulk flow applications. No persons may be transported on the conveyor. Operation, Maintenance, and Service All work on the conveyor must be performed in accordance with the instructions, the technical specifications of the conveyor, the system documentation, and the following additional regulations in their latest edition: national regulations on the installation and operation of electrical installations accident prevention regulations other statutory government regulations and safety rules of professional associations In order to prevent any danger to users or other persons or damage to the conveyor, all assembly, servicing, maintenance, and operational work on the conveyor has to be carried out by properly Work on electrical equipment may only be carried out by qualified electricians. Warning: Before starting any assembly, maintenance, and service work, make sure the main switch of the system is turned off and secured against being turned on again per your local lockout/tag-out procedures. Safety equipment For mechanical protection, various cover plates and finger guards are fitted to the belt conveyor. These protective parts may only be removed for assembly, maintenance, and service purposes. Warning: When carrying out adjustment work without safety equipment or guarding in-place, be aware that there is a danger of an accident. Secure the danger area against access by unauthorized personnel. trained personnel. 5 P a g e!!

6 Further safety equipment for the complete conveyor system and the transfer sections are typically described in the conveyor system documentation (spring rollers, covers, position of emergency stop switches etc.). Operating conditions The belt conveyor in its standard design should only be operated when fixed to a solid foundation. Special equipment accessories allowing mobile operation are described in the technical specifications. The belt conveyor is not explosion-protected and may only be operated under the following ambient conditions: Air temperature 0 C up to 50 C (32 F up to 120 F Relative humidity 90% Normal atmosphere o no oil or gas atmospheres o no corrosive atmosphere o no caustic atmosphere Securely protected against precipitation and against direct sunlight onto the belt surface Deviations from the conditions are described in the technical specifications. 6 P a g e

7 Description TS4200/150 Junctions The TS junction can be configured to operate as either a Merging or Diverting Conveyor and is available in 45 and 30 configurations. The centerline length is available from 42 up to 120. All conveyors of this type consist of a conveyor frame supporting and containing a composite slider bed, drive and tail pulley, snub roller, tracking station and a belt. The belt is driven by a 150mm diameter drive pulley. A snub roller supplies belt tracking tension. Belt tracking is via the snub roller. All tracking is done at the Offset Belt Return Station The drive and tail pulleys of the junction are supplied with non-replaceable shafts standard. Standard shaft diameter is 1-7/16in. Replaceable shaft pulleys are available as an option. The tail pulley shafts come standard with drilled and tapped ends 3/8-16x1. The tail pulley is relocated from the inline station to the offset station when the junction is configured as a diverting conveyor. An exception is for very short centerlines (CL < BF). The junction is then a reverse running merge conveyor. Conveyors can be supplied with sideguards. The minimum height for the guards is 0in (no guards) and maximum is 36in. The guards are set at the customer requested width for the conveyor. Funneling or positioning guards can be designed at customer request. Merging Conveyors The TS Merging conveyor is driven from the offset belt return station and moves product from the straight end to the angled end. Diverting Conveyors The TS Diverting conveyor is driven from the inline belt return station and moves product from the angled end to the straight end. 36 Centerline Junction The TS Junction is also available in a 36 centerline conveyor. Both merging and diverting junctions are configured as a merge but the belt is pushed when used as a diverting conveyor. The tracking station must be configured for correct flow. 7 P a g e

9 Installation Uncrating All Transnorm modules are shipped in palletized open-sided crates to protect the conveyors during shipment unless special crating requirements are requested by the customer. It is good practice to photograph the conveyor and crate immediately upon receipt to document any shipping damages and to account for all product sections. The best practice is to leave the conveyor module in the crate until it is required and relocate the crate as close as practical to the installation position. Uncrate the conveyor or conveyor components by removing the top and sides of the crate using standard pry-bars and hammers. Use good hygiene with the discard wood as nails may be protruding. Protect the belt material or surface from damage during the uncrating process. The conveyor frame is secured to the shipping pallet by means of shipping brackets. First remove the brackets from the shipping pallet and then remove the brackets from the conveyor frame! Note: All Units are shipped with the belt tensioned for proper operations. No adjustments are required. Positioning Using the integrator layouts (shop drawings), identify and mark critical positions and elevations for the conveyor, conveyor sections and any conveyor interfaces. Install junctions so that they are level (typical) to the elevations on the system level drawings. When floor supports are required, the standard Transnorm supports are designed to readily mount to the conveyor frame. 9 P a g e

10 Supports Typical supports for the TS4200/150 conveyor are tubular steel with an adjustable uni-strut foot (referred to as TS Inc. Supports). Supports consist of three single legs and one H-Frame Weldment. The H-Frame is available as a Channel Support if requested. Ceiling Supports are also available if requested. Typical TS Inc. Supports 10 P a g e

11 Operations Standard Operations The TS is supplied in a wide variety of length and width combinations, and operates a belt speeds between 10fpm and 400fpm. For very heavy starting loads (greater than 20lbs per inch of drive pulley width) and/or speeds in excess of 300fpm and for all operations requiring a 5hp or larger motor, a motor soft-starter or VFD is mandatory to keep the warranty in-force. A soft start will also prevent damage to the drive assembly, drive pulley, and belt system. All Transnorm supplied bearings are considered lubed-for-life and no maintenance or other consideration is required. All units are shipped with the belts tensioned for proper operations. High Temperature Operations For intermittent peak very high temperature (>140deg F) or sustained high temperature (>120deg F) operations, the drive reducer oil life will be shortened. Gear reducer oil should be changed more often and substituted with hightemperature specific synthetic lubricant. Low Temperature Operations For intermittent very low temperatures (< 20F) or sustained low temperature (>32def F) operations, the gear reducer oil should be changed to lowtemperature specific synthetic lubricant. The main bearing grease may require replacement as well. 11 P a g e

12 Maintenance Standard Preventive Maintenance The Transnorm TS Belt conveyor is designed to require only periodic inspections and cleanings under normal operating conditions. Time Period Action Comment Monthly Observe the TS Remove trash and other debris, particularly around the sideguards and pulley end-guards Regular observations and cleaning of any conveyor equipment typically greatly reduces unscheduled maintenance costs and down time. Regular cleaning of material handling debris greatly reduces chances of belt jams, belt tears, and all other premature wear. Quarterly Annually Inspect rolling and rotating components for rough bearings. Inspect conveyor for loose hardware. Verify that junction controls are available to identify jam conditions. Inspect belt and belt-beading interface for signs of wear or foreign object damage. Rough bearings can be identified by higher than normal noise generation, leaking or weeping grease, or bearing discoloration (bluing). Block Photoeyes to check for proper jam logic. Quick discovery prevents conveyor and product damage. Pay particular attention to the ends of the bead and to the stitching. Belts with worn stitching should be repaired at Transnorm and are usually an indicator that the belt tracking was missaligned. 12 P a g e

13 Tracking the Belt! Warning: Observe local safety regulations. As the belt should be tracked with the guards removed, limit the access to the conveyor to as few maintenance personnel as possible and only to skilled technicians who are trained in all local safety and emergency procedures. To track the belt: Track and tension the belt as loose as possible to carry the load without slipping Remove the outer offset station cover from the conveyor. Square the drive pulley to the conveyor frame, 10mm to 20mm from the end of the frame. Move the snub roller all the way to the end of the side plate slot. Start the unit and make the necessary adjustments to the snub roller to center the belt between on the slider table. 13 P a g e

15 ! Note: Belt tension on the junction can be very low as the large pulley face and drive snub allows for significant drive torque to be transmitted to the belt and belt tension is not required for belt tracking. After tracking is accomplished, run the conveyor for minutes to fine tune the tracking. Replace the side guides/guards and the outer perforated guards and return the conveyor to service. Gearmotor Maintenance Typically, gearmotors or electric motors and gear-reducers only require proper lubrication and cleanliness for proper performance and long service life. The lubrication oil change interval is described by the gearmotor or reducer manufacture. Transnorm System recommends that when possible by reducer specification, synthetic lubricants be used to extend service life between changes and provide an increased operational temperature range. Electric motors typically do not have any provisions for lubrication. Bearing Lubrication All bearings used in the TS should be considered Lubed-for-Life. The main pulley bearings are not normally equipped with a grease-zerk and no grease is required for normal service operations. 15 P a g e

16 Conveyor Repair! Warning For all repair/replacement activities, follow local and national safety procedures. Consult the CEMA Unit Handling safety video for general practices and procedures. Always isolate power to the motor prior to performing any repair activities. Conveyor Belt Replacement! Warning Junction pulleys and snub rollers are very heavy. Use appropriate lifting methods when handling these parts. Endless Belt Removal Remove both sideguards and deckboards. Loosen the drive and tail pulley bearings and remove the drive and tail pulleys.
