The turnstile holds up to 60 t; the worked example below checks packing pace and pallet stack.<\/p>\n<p>The video below shows the demonstration line \u2014 coils wrapped in white film on a yellow roller line and stacked by a yellow-armed stacker, all fenced in by yellow railings:<\/p>\n<iframe loading=\"lazy\" width=\"358\" height=\"636\" src=\"https:\/\/www.youtube.com\/embed\/MEVAMtNxh34\" title=\"la maquina de l\u00ednea autom\u00e1tica de envasado de bobinas con sistema de apilado de bobinas\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2>Why pack slit coils in one line<\/h2>\n<p>A slitter turns one master coil into a set of narrow coils at once. If they are then turned, wrapped and stacked by crane one by one, packing becomes the slowest part of the shop, and every crane lift risks damaging an edge. This line takes the whole set from the slitter and passes every coil from station to station.<\/p>\n<h2>Turnstile: the buffer after the slitter<\/h2>\n<p>A heavy rotating stand with 2 or 4 arms: the slit set loads on one arm while coils on another are packed, decoupling the slitter from the packing pace. Arm count suits slitting line speed; each turnstile takes up to 60 t on arms up to 2,000 mm long.<\/p>\n<h2>Down ender: from eye horizontal to the conveyor<\/h2>\n<p>The down ender picks one coil at a time off the turnstile arm. A hydraulic lifting nose adjusts to coil width, then lays the coil on its roller conveyor table, a falling-protection device holding it during the turn.<\/p>\n<h2>Eye-through wrapper<\/h2>\n<p>The wrapper has its own conveyor table, so it connects straight into the line. The ring passes the film through the coil eye while rollers turn the coil. Ring and roller speeds each run on an inverter with adjustable film tension, so overlap and tightness can be set per coil size.<\/p>\n<h2>Gantry stacker<\/h2>\n<p>A gantry-type mechanical coil lifter picks each wrapped coil off the conveyor and sets it on the pallet. Stacks reach up to 1,000 mm high including the pallet, with up to 3,000 kg per coil and 6,000 kg per stack.<\/p>\n<h2>Line data<\/h2>\n<table>\n<thead><tr><th>Station<\/th>\n<th>Key data<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Turnstile<\/td>\n<td>2 or 4 arms, up to 60 t, arms up to 2,000 mm<\/td><\/tr>\n<tr><td>Down ender<\/td>\n<td>hydraulic lifting nose, falling protection, roller conveyor table<\/td><\/tr>\n<tr><td>Wrapper<\/td>\n<td>eye-through, ring and roller speed on inverters, adjustable material tension<\/td><\/tr>\n<tr><td>Stacker<\/td>\n<td>gantry type, stack up to 1,000 mm with pallet<\/td><\/tr>\n<tr><td>Stack load<\/td>\n<td>up to 3,000 kg per coil, 6,000 kg per stack<\/td><\/tr>\n<tr><td>HMI<\/td>\n<td>10 or 12 inch touch screen<\/td><\/tr>\n<\/tbody><\/table>\n<h2>Worked example: slit set, pace and pallet<\/h2>\n<p>A service centre slits a master coil of 1,500 mm OD, 508 mm ID and 1,250 mm width into 10 strips of 120 mm, with 50 mm of trim, taking 15 minutes per master coil. Illustrative customer figures.<\/p>\n<p><strong>Turnstile load.<\/strong> The master coil&#8217;s cross-section is \u03c0 \u00f7 4 \u00d7 (1.5\u00b2 \u2212 0.508\u00b2) = 1.564 m\u00b2; times 1.25 m and 7,850 kg\/m\u00b3 gives 1.564 \u00d7 1.25 \u00d7 7,850 = 15,350 kg, or 15.4 t \u2014 far below 60 t.<\/p>\n<p><strong>One slit coil.<\/strong> Each 120 mm strip weighs 1.564 \u00d7 0.12 \u00d7 7,850 = 1,473 kg.<\/p>\n<p><strong>Packing pace.<\/strong> Ten coils in 15 minutes means one coil every 900 \u00f7 10 = 90 s, so each station must finish within 90 s per coil or the turnstile fills and the slitter waits. The published FHOPE description quotes a 60 s down-ending cycle for the slit coil system, which fits inside that budget \u2014 time the other stations the same way.<\/p>\n<p><strong>Pallet stack.<\/strong> At 1,473 kg, four coils weigh 5,892 kg, inside the 6,000 kg limit, and stand 480 mm high \u2014 well under the 1,000 mm cap. Each slit set fills two pallets of four and one of two.<\/p>\n<p><strong>General rule.<\/strong> The slowest station sets the line: its time per coil must be at most T_slit \u00f7 n (slitting time per master coil \u00f7 number of strips).<\/p>\n<h2>Selection checklist<\/h2>\n<ol>\n<li>Master coil OD, ID, width and weight.<\/li>\n<li>Number and width of strips.<\/li>\n<li>Slitting time per master coil.<\/li>\n<li>Wrapping material: film, paper or both.<\/li>\n<li>Pallet size and stack limits.<\/li>\n<li>Floor space; how pallets leave the line.<\/li>\n\n<h2>Safety<\/h2>\n<p>For CE-market deliveries, EN 415-10 is referenced as the design basis for packaging machines and ISO 12100 as the risk-assessment method; guarding is fixed for your line during factory integration. Main hazards: the turning turnstile, the down ender, the wrapping ring and the moving stacker. Fence the line and interlock access gates, keep the stacker and turnstile zones clear while they move, and add light curtains or area scanners where people need open access.<\/p>\n<h2>Engineering FAQ<\/h2>\n<p><strong>Two arms or four on the turnstile?<\/strong> It depends on your slitting line speed; more arms give more buffer between slitting and packing.<\/p>\n<p><strong>Can the line handle different coil widths?<\/strong> Yes \u2014 the down ender&#8217;s lifting nose adjusts, and wrapper settings change per coil.<\/p>\n<p><strong>Can we choose the PLC brand?<\/strong> Yes: Siemens, Rockwell, Mitsubishi or Omron.<\/p>\n<h2>Next step<\/h2>\n<p>Email your master coil size, strip layout and slitting time to info@fhopepack.com, and we confirm the turnstile, wrapper and stacker with a
