General safety and design considerations General safety and design considerations Introduction 1.1.1 Critical factor To achieve an operational installation which is reasonably safe for all people involved in its use and maintenance, it is necessary to consider certain as- pects. This is done when designing a conveyor system. The chain is gen- erally the critical factor to consider with guarding.

Introduction This maintenance manual contains directions for the standard components sold through the X85 chapter of the FlexLink main catalogue. For non-Flex- Link components, such as motors, pneumatic equipment, control systems etc., the manufacturer’s maintenance instructions apply. In general, main- tenance instructions are not given for equipment which the customer has chosen and specified for fitting to the installation.
Maintenance Introduction to drive units 3.3.1 Three types There are three different types of drive units: end drive, intermediate drive and horizontal bend drive units End drive units End drive unit with return chain, located at the ‘pulling’ end of the conveyor.
Maintenance Slip clutch adjustment 3.4.1 Introduction The slip clutch on the drive unit is a safety device which allows the chain to stop if the load becomes excessive. It has two purposes: • Prevent damage to conveyor • Prevent damage to the products on the conveyor Where a slip clutch is fitted, it must be adjusted so that it does not slip whenever the drive unit is started under full load.
Page 17
Maintenance 3.4.2 Clutch adjustment 1 Remove the drive unit protection cover. 2 Use an Allen key, 3 mm, to loosen the screw (1) on the slip clutch so that the adjustment nut (2) can be freely rotated. 3 Turn the adjustment nut (2) clockwise with a hook spanner until the arrow on the nut is aligned with the desired F...
Maintenance Inspection – drive units 3.5.1 Roller chain transmission The roller chain transmission should be checked and lubricated after 50, 250, 500 hours of operation, and then every 500 hours. If the roller chain transmission is not fitted with a chain tensioner the chain tension should be checked on this occasion.
Page 19
Maintenance 3.5.4 General checks on drive unit Carry out a general inspection of the drive unit. • Check particularly that the protective covers for the roller chains are complete and firmly in place. • Replace damaged/worn parts. 5814EN-3...
Maintenance Inspection – conveyor chains 3.6.1 Conveyor chains The most common types of conveyor chains are: • Plain conveyor chains • Chain with flexible cleats for vertical wedge convey- • Chain with friction surface for conveyors with an in- cline up to 30°. The friction surfaces are normally dis- tributed over the chain at a predetermined distance.

Maintenance the chain. The stretch shows itself as slack on the return side of the drive unit. The tension of the conveyor chain should be checked after 50, 250, 500 hours of operation and thereafter every 500 hours. In operation there will be some slack in the conveyor chain. How much ac- ceptable slack depends on the length of the conveyor chain.

Maintenance • by removing the side plates of the drive or idler end unit in closed systems. • at a wheel bend by removing the outer curve. • at a conveyor beam section for liftable chain (if there are any). Instructions 1 Make the conveyor chain accessible at some of the overhead positions.
Page 23
Maintenance 3 Remove the necessary number of link NB: With cleated or friction chains, pay attention to the divisions between the links. 4 Join the chain together with a new pivot. NB: The old pivot should not be re- used. When the chain is divided, a new pivot must always be fitted.
Maintenance Inspection – slide rails, beams, idlers, bends 3.7 .1 Checking slide rails The condition of the slide rails is fundamental to the functioning of the in- stallation. It is therefore essential that these are in good condition. 3.7 .1.1 Checking the slide rail with the conveyor chain in place The slide rail must be checked after every 250 hours’...
Page 25
Maintenance 3.7 .1.2 Checking the slide rail, conveyor chain removed At least once a year or after every 2 000 hours’ operation, the chain should be removed from the beam, and the slide rail carefully checked for wear and fastening. Plain bends should be checked after every 500 hours’...
Maintenance Inspection – safety devices Protective and safety devices Safety devices should be checked at regular intervals. • Check the protective cover on the cleated chain conveyor return chain. • Drive units type H, have a slack protection for the conveyor chain. Check that the slack protection plates are in place, and that the chain does not slacken enough to hang below the plates.
Maintenance Replacement of worn parts – conveyor chain 3.9.1 Removal of conveyor chain Ensure that the power to the drive motor is disconnected. Disengage the motor; there are various methods depending on the type of drive unit: – Detach the slip clutch. –...

Important safety precautions 5.1.1 Dismantling Dismantling of the FlexLink conveyor system should be carried out by com- petent persons, who are familiar with the equipment being decommis- sioned. In the absence of detailed information, every care should be taken to en- sure that all items are securely retained during the decommissioning pro- cess.
System dismantling and disposal Dismantling end drive units with suspended motor The locking effect of the slip clutch can be removed by removing the trans- mission chain or by releasing the slip clutch (section in maintenance and service refers to slip clutch adjustment). Remove the motor gear unit from the conveyor drive assembly.

System dismantling and disposal Dismantling end drive units, no slip clutch Remove the motor gear unit from the conveyor drive assembly. The motor gear unit may be fitted with an oil breather. Ensure that the oil from the gearbox cannot leak into the surrounding area when decommissioned. Oil should be drained from the gearbox and disposed of in accordance with lo- cal environmental regulations.
System dismantling and disposal Remove the conveyor chain Split the conveyor chain using the pin insertion tool and remove the con- veyor chain. If removing conveyor chain from over head conveyor special attention should be given when removing the last few metres. The weight of the removed chain accelerates the removal from the conveyor beams and can cause injury when the last links exit the extrusion.
System dismantling and disposal Dismantling end drive units Unscrew the inner grub screws from the drive unit connector strips and re- move drive end from the conveyor. Repeat for idler end unit. 5814EN-3...
System dismantling and disposal Remove slide rails Remove the slide rail on all sides of the conveyor extrusion. Remove the slide rail retaining fixings by drilling away the rivets or plastic screws and pulling away the slide rail from the aluminium extrusion profile. 5814EN-3...
