Pallet system XK overview

1 Pallet system XK overview Standard functions from FlexLink 5331EN-1 XK pallet system with configurable standard functions and RFID The XK pallet system is a complete system for handling of individual products on a product carrier (pallet). An automated system is built on configurable standard functions. Standard functions makes it very easy and fast to create simple as well as advanced layouts for routing, balancing, buffering and positioning of pallets. RFID identification in the pallets enables one piece track and trace and logistic control for the production line. A standard line cabinet with power bus and communication bus systems provides fast installation and high flexibility for future changes. Standard features Divert/merge devices are used for routing products by dividing or combining flows of products. Usually there is a main conveyor, a "highway", and separate subordinated conveyors, "satellites". On the satellites, products can be subjected to various operations such as turning, grinding or testing, without disturbing the main flow. After the operations, the products can return to the highway. Function specification 5331EN-1 1

2 Pallet system XK overview Divert/merge devices Divert/merge devices are used for routing products by dividing or combining flows of products. Usually there is a main conveyor, a "highway", and separate subordinated conveyors, "satellites". On the satellites, products can be subjected to various operations such as turning, grinding or testing, without disturbing the main flow. After the operations, the products can return to the highway. A combination of a highway and one or more satellites is often called a cell. Using divert/merge functions, it is possible to build cell junctions which facilitate transfer of a pallet from one cell to another. See figure.

3 Product range Divert functions DL Diverters for guiding the flow of products off the highway into a satellite are available in eight types: 45 left/right and 90 left/right, each with either 42 mm or 101 mm guide rail. The diverter includes a pneumatically controlled wiper arm. Merge functions DR Merge devices for guiding products from a satellite back to the highway are available in eight versions: 45 left/right and 90 left/right, each with either 42 mm or 101 mm guide rail. DL DR ML MR ML MR Configurator tool The divert/merge/combination modules can be individually configured to the right pallet size by the FlexLink configurator tool. The configurator tool will create a geometrically correct 3D CAD-model that can be inserted in the layout. The configured product will include the function, conveyor beams, wheel bends and guide rails. You can also configure: Guide rail type Stops Type of sensors and brackets RFID readers and brackets Drip catchers and drip pans 1 Combined divert/merge functions CL CR CL CR R L The divert/merge devices with 101 mm guide rail can be equipped with drip pans. The drip pans are designed to collect fluids from the divert/merge area including nearby drive units or idler end units. Drip pan kits for diverters and merge devices include two drip pans: one for the wheel bend and one for the drive unit or idler end unit. See figure. Standard XK drip trays should be mounted slanting away from the drip pans, and be equipped with end caps at the end facing the drip pans belonging to the divert/merge devices. Devices which permit products to be guided into a satellite, or be returned back to the highway, or circulate on the satellite, are called Divert/merge combinations. They are available in eight versions: 45 left/right and 90 left/right, each with either 42 mm or 101 mm guide rail. The diverter part includes a pneumatically controlled wiper arm.

4 Product range (continued) Pallet positioning functions Pallets with RFID The pallet locating stations for conveyor system XK are used for positioning of all FlexLink pallets type XKPP. The pallets are stopped by a pneumatically controlled stop device near the desired position. A proximity switch is used to indicate that a pallet is in the locating station. Here, two rulers lift the pallets approximately 1,5 mm above the chain. The two locating guide pins ensure a high locating accuracy (±0,1 mm). The pallet locating station is available for straight conveyor sections and for 180 bends. For low position accuracy a regular stop mechanism type XKPD can be used. These functions can be individually configured to the right pallet size by the FlexLink configurator tool. The configuration tool will create a geometrically correct 3D CAD model that can be inserted in the layout. You can also configure: Guide rail type Stops Type of sensors and brackets RFID readers and brackets FlexLink conveyor system XK includes pallets in three sizes. A pallet consists of a cast aluminium pallet base and two plastic guide discs, reinforced with hardened steel slide plates at the bottom. Product-specific fixtures are attached to the pallet base. Two hardened bushings at the bottom of the pallet base provide high locating accuracy at the locating station. Two guide holes in the pallet base ensure high accuracy for the product-specific fixture in relation to the bushings. The guide discs have a hardened steel surface to face the conveyor chain. An initiator plate for position sensors is integrated in each guide disc. The pallets are delivered with shock absorbers. An RFID tag is embedded in a plastic holder that is integrated in the underside of the pallet base. Accumulation of pallets in conveyor bends is possible. Note, however, that pallet type XKPP cannot be accumulated through 180 bends. XK pallets can be used for inclines up to 3. 4 Function specification 5331EN-1
