The video below shows the handling cell at the start of the line: a robot arm grips the coil, lifts it clear, turns it and presents it for the strap-removal step, then passes the coil to an inclined conveyor. Coil size, strap pattern and line pace are confirmed per project. This guide explains the de-strapping cell, what the robot does, what to specify and what to verify before acceptance, for plant engineers and coil-line buyers.<\/p>\n<iframe loading=\"lazy\" width=\"358\" height=\"636\" src=\"https:\/\/www.youtube.com\/embed\/47L-LanSMVA\" title=\"Coil De-strapping Machine\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2>The De-strapping Cell Sequence<\/h2>\n<table>\n<thead><tr><th>Step<\/th>\n<th>What happens<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Coil arrival<\/td>\n<td>A heavy coil arrives on the line, still strapped.<\/td><\/tr>\n<tr><td>Robot picks<\/td>\n<td>The robot arm grips the coil, lifts it clear of the conveyor and positions it.<\/td><\/tr>\n<tr><td>Strap removal<\/td>\n<td>The presented strap is cut and pulled clear while the coil is held firmly.<\/td><\/tr>\n<tr><td>Coil hand-off<\/td>\n<td>The freed coil is turned or oriented as the next station needs it.<\/td><\/tr>\n<tr><td>Discharge<\/td>\n<td>The coil is placed on an inclined conveyor to the next process.<\/td><\/tr>\n<\/tbody><\/table>\n<p>Doing this by robot removes the manual cut-and-pull step that strains operators and risks the coil edges.<\/p>\n<h2>What the Robot Does<\/h2>\n<table>\n<thead><tr><th>Function<\/th>\n<th>Why it matters<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Grip<\/td>\n<td>A dedicated gripper holds the coil without damaging edges.<\/td><\/tr>\n<tr><td>Lift<\/td>\n<td>Takes the coil clear so strapping can be accessed from every side.<\/td><\/tr>\n<tr><td>Turn\/orient<\/td>\n<td>Rotates the coil to present each strap and to meet the next station&#8217;s orientation.<\/td><\/tr>\n<tr><td>Place<\/td>\n<td>Sets the coil on the outfeed with repeatable position.<\/td><\/tr>\n<tr><td>PLC hand-off<\/td>\n<td>Signals the line so the next step starts only when the coil is placed.<\/td><\/tr>\n<\/tbody><\/table>\n<p>The exact motions (grip range, turns, place position) are set from the coil family you process, and confirmed per project.<\/p>\n<h2>What to Specify<\/h2>\n<table>\n<thead><tr><th>Input<\/th>\n<th>Why it matters<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Coil outer\/inner diameter, width, weight<\/td>\n<td>Sets gripper range, robot payload and reach.<\/td><\/tr>\n<tr><td>Strap pattern (number, position)<\/td>\n<td>Sets how many cut\/pull moves each cycle needs.<\/td><\/tr>\n<tr><td>In and out orientation<\/td>\n<td>Sets turns and the outfeed angle.<\/td><\/tr>\n<tr><td>Strap material and closure<\/td>\n<td>Steel or PET\/PP band and the closure type select the cutter\/puller tooling; waste-band removal is stated too.<\/td><\/tr>\n<tr><td>Cycle time<\/td>\n<td>Sets robot speed and gripper design.<\/td><\/tr>\n<tr><td>Line interface<\/td>\n<td>Sets PLC hand-off and safety interlock.<\/td><\/tr>\n<tr><td>Environment<\/td>\n<td>Sets robot cabinet\/grade (dust, wash-down, coil oil).<\/td><\/tr>\n<\/tbody><\/table>\n<h2>Factory Testing and Acceptance<\/h2>\n<ol>\n<li><strong>Full-cycle evidence.<\/strong> A test log of complete pick \/ strap-cut \/ turn \/ place cycles on a representative coil.<\/li>\n<li><strong>Extended run.<\/strong> The vendor&#8217;s stated practice on this machine family includes near-continuous pre-delivery testing (up to about 24 hours where stated).

Coil size and strap pattern decide the gripper and robot.<\/p>\n<p><strong>Q: Does the robot remove all strap types?<\/strong><\/p>\n<p>A: It is set to your strap type (steel or plastic band) and pattern; the cut-and-pull end effector is selected per project.<\/p>\n<p><strong>Q: Can it be integrated with my existing line?<\/strong><\/p>\n<p>A: Yes, via PLC hand-off and standard conveyor heights. Give the manufacturer your outfeed conveyor and orientation requirements.<\/p>\n<p><strong>Q: What safety standards apply?<\/strong><\/p>\n<p>A: The cell is designed with EN 415-10 as the machinery safety reference and an ISO 12100 risk assessment for the robot cell and adjacent conveyors; certification status is confirmed at FAT.<\/p>\n<h2>Next Step<\/h2>\n<p>Send coil OD\/ID\/width\/weight, strap pattern, in\/out orientation, cycle time and line interface so the robot cell and gripper are sized on the approval drawing.<\/p>\n<h2>Related Resources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-steel-coil-packing-line-2\/\">Coil Packaging: Operation and Applications<\/a> \u2013 The full coil packing sequence this de-strapping cell feeds.<\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Coil-upender.html\">Coil Upender &amp; Industrial Turnover Solutions<\/a> \u2013 Coil handlers used across coil lines.<\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-180-turning-machines-work-for-precast-components-and-sheets-in-the-production-process\/\">How 180\u00b0 Turning Machines Work for Precast Components and Sheets<\/a> \u2013 EN 415-10 \/ ISO 12100 safety reference notes.<\/li>\n<\/ul><\/ol><\/ol>","protected":false},"excerpt":{"rendered":"<p>Overview A coil de-strapping machine removes the straps from heavy steel coils under control instead of by hand.
