Modular pallet conveyor system XT System description Module concept The XT conveyor is a twin-track, flexible plastic chain pallet conveyor. The system is especially well suited for manual and automatic assembly and test systems in the automotive and electrical/electronics industries. The modular concept allows simplified engineering and ordering, as well as fast configuration together with plug and play capabilities for improved productivity. The standard modules can be split into six groups – conveyors, transfers, stops, locates, lift-and-rotates and supports. Each module is quickly adaptable and reusable for ELV future demands and can easily be integrated with FlexLink’s large range of single strand pallet conveyor sys- CTL tems. Pallets Examples of application areas Manual and automatic assembly and test systems in the automotive and electrical/electronics industries. Examples: gearboxes, computers, sewing machines, mobile phones, automotive seat guiderails, eyeglasses, injection-moulded parts, fishing reels, car instrument kits FlexLink´s standard chains and integrated guide rails systems allow for accumulation through the entire system, including bends, as well as easy and straightforward integration of stops, locate stations as well as transfer units with a minimum of controls.

Introduction (continued) System data Typical noise levels 25 m maximum conveyor length 20 m/min maximum conveyor speed Standard pallet sizes from 240×240 mm up to 640×640 mm, including rectangular sizes 30 kg maximum pallet weight (8 kg pallet weight/100 mm conveyor During normal conditions a noise level below 65 dB(A) can be obtained in an XT conveyor system, including transfers, stops, etc. However, be aware that the pneumatic components (valves, etc.) very much affect the noise level if they are not enclosed correctly. Also, throttle valves must be adjusted correctly at transfers, stops, etc....

System overview Typical XT conveyor layout The figure below shows a typical conveyor layout, built by connecting various XT modules. Note that support modules are not shown in this overview. For each conveyorand transfer module, a support module has to be ordered separately, see page 343, “XT support modules”. Serial workstation The figure to the left shows a modular breakdown of the XT layout shown above. Pallet flow in a highway Characteristic for a highway is a continuous circulation of pallets, waiting for calling from a transfer operation into a parallel flow, for instance a workstation....

System overview (continued) Available XT modules Below is an overview of the various modules presented. The conveyor modules can be connected back to back to form the desired conveyor layout. Transfer and locating modules can be incorporated as required. For more information about the modules, please see the detailed information under each module section later on in this document. System overview

Pallet width (PW) × pallet length (PL) Slide rail configuration Pallet width and pallet length. PL is basically the pallet dimension in the direction of pallet movement in the main flow. In some modules the pallet moves “sideways”, for example when transferred from one line to another. See the module descriptions for PL/PW definitions in each specific case. The figure below shows an example. The following figures show the four different slide rail options applicable to XT conveyors. G0: No pallet side guides G2: Pallet side guides G4: No pallet side guides, protection of return chain The length...

Definition of parameters (continued) Motor type (MT) The motor unit can be mounted on the: Queue stop is used for queue accumulation Left side of the conveyor Right side of the conveyor Below the conveyor (mid-mounted) Left/Right refers to the location of the motor in relation to the direction of chain travel. See figure. Pallet damping (D) This parameter determines if a non-shock absorbing or shock absorbing stopper is needed. • No damping of pallet, max queue 200 kg (D00) Max damping of pallet, max queue 35 kg (D01) Max damping of pallet, max queue 100 kg (D02). Use of F depends on module....

General information (continued) General dimensions * Minimum length of conveyor beam section. Attachment of a support module normally requires more space in this section than 180 mm. Near a drive unit** or idler end unit** (Fig. A), or a wheel bend*** (Fig. B), the T-slots are occupied by connecting strips. General information

Technical information (continued) Friction between chain and pallet In most cases, the coefficient of friction for contact between plain chain and pallet is between 0,1 and 0,35. Temperature limits A conveyor can operate continuously at environment temperatures from –20 °C to +60 °C. Temperatures up to +100 °C can be tolerated for short periods (cleaning, rinsing). Maximum conveyor length The maximum length of a conveyor depends on the tension in the chain, the speed, and the capacity of the drive unit. It is important to calculate and compare the maximum chain tension and the capacity of the...

XT Compact conveyor module XT conveyor modules (continued) Conveyor module S11 Compact Straight conveyor, Compact Conveyor module type J51 Conveyor module type J52 Straight conveyor module, Compact XT Compact products use standard 1-phase motors, 240 V 50 Hz or 115 V 60 Hz. For use as stand-alone unit, as perpendicular link between two XT conveyor modules, or in-line with another conveyor module. Reversible operation is possible. The module is delivered fully assembled. Configuration: see page 342. The Compact series modules use a different type of conveyor beam and chain as compared to other...
