This method is particularly effective for light loads, such as empty plastic bottles, where a turntable system might cause instability. The RAS100 model automates this process in a conveyor line, handling film clamping, cutting, and wiping without manual intervention.<\/p>\n<h2>Overview<\/h2>\n<p>The following video demonstrates the operational sequence of the RAS100 rotary arm wrapper. It shows the machine in a standby state with a pallet of transparent plastic bottles positioned on the central conveyor platform. The yellow rotating arm remains above the load before initiating movement.<\/p>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/22rB97DRgM8?rel=0\" title=\"Rotate arm stretch wrapping machine, pallet wrapping machine\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2>Why keep the pallet stationary?<\/h2>\n<p>Light, unstable loads such as empty plastic bottles, light cartons, or tall mixed stacks lack the weight to hold themselves in place during rotation. In a turntable system, the pallet spins with the load, which can cause top layers to shift outward before the film secures them.<\/p>\n<p>On the RAS100 rotary arm wrapper, the pallet remains still on the conveyor. Only the arm and the film carriage move. This ensures that nothing pushes the stack sideways except the film itself, and the force applied is controlled by a separate motor rather than centrifugal force.<\/p>\n<h2>How does the automatic cycle work?<\/h2>\n<p>The machine follows a five-step automatic cycle designed for integration into a conveyor line.<\/p>\n<ol>\n<li><strong>Infeed:<\/strong> The conveyor carries the pallet under the arm and stops it in the wrapping station.<\/li>\n<li><strong>Hold:<\/strong> A stabilizer plate descends onto the top of the load to secure it.<\/li>\n<li><strong>Wrap:<\/strong> The rotary arm grips the film end on the load. The arm rotates while the carriage climbs steadily, spiraling the film up the stack.<\/li>\n<li><strong>Finish:<\/strong> Depending on the program, the wrap may continue on the way down. The sealing arm then seals the film end and cuts it.<\/li>\n<li><strong>Outfeed:<\/strong> The stabilizer plate lifts, and the conveyor moves the pallet to the next station.<\/li>\n\n<p>The program allows for extra wraps at the foot, middle, and top of the stack, with settings ranging from 0 to 99 turns for each section.<\/p>\n<h2>How is the film handled automatically?<\/h2>\n<p>The RAS100 features an automatic film clamp and cut unit that operates without an operator. Scissor-like gripper bars clamp the film, an instant heating wire cuts it, and a soft brush wipes the tail flat onto the load. The clamp then holds the new film end, ready for the next pallet.<\/p>\n<p>An optional top cover device can lay a sheet over the pallet before wrapping. The film then binds the sheet&#8217;s edges into the wrap, providing protection against dust and rain.<\/p>\n<h2>What are the RAS100 specifications?<\/h2>\n<p>The following table outlines the technical specifications for the RAS100. Note that load height and carriage speed are matched to your specific pallets when a quote is prepared.<\/p>\n<table>\n<thead><tr><th>Item<\/th>\n<th>RAS100 Specification<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Working mode<\/td>\n<td>Automatic, in conveyor line<\/td><\/tr>\n<tr><td>Output<\/td>\n<td>10\u201330 pallets per hour<\/td><\/tr>\n<tr><td>Rotary arm speed<\/td>\n<td>10\u201314 r\/min, inverter controlled<\/td><\/tr>\n<tr><td>Largest load footprint<\/td>\n<td>1,400 \u00d7 1,400 mm<\/td><\/tr>\n<tr><td>Stretch film<\/td>\n<td>LLDPE, 500 mm wide, 76 mm core, 15 kg roll<\/td><\/tr>\n<tr><td>Film tension<\/td>\n<td>Set by its own motor<\/td><\/tr>\n<tr><td>Extra wraps<\/td>\n<td>0\u201399 at foot, middle, and top<\/td><\/tr>\n<tr><td>Film handling<\/td>\n<td>Pneumatic clamp, hot-wire cut, brush wipe<\/td><\/tr>\n<tr><td>Load height sensing<\/td>\n<td>Photo-eye<\/td><\/tr>\n<tr><td>Protection<\/td>\n<td>Anti-collision loop on the carriage<\/td><\/tr>\n<\/tbody><\/table>\n<p>The stabilizer plate belongs to the standard automatic cycle in the manufacturer&#8217;s sequence; whether it ships as standard on a given unit, or as a fitment for light or tall stacks, is stated in the technical specification for the project.<\/p>\n<h2>How is capacity calculated?<\/h2>\n<p>Capacity calculations are based on illustrative scenarios rather than fixed measurements. For example, if a bottle maker ships empty plastic bottles stacked 1,800 mm tall on 1,200 \u00d7 1,000 mm pallets, the footprint fits within the 1,400 \u00d7 1,400 mm limit.<\/p>\n<p>With 500 mm film and 50% overlap, the carriage climbs 250 mm per turn. An up-only wrap for a 1,800 mm stack requires 7.2 turns. Adding three reinforcing turns at the bottom and three at the top results in 13.2 turns total. At an arm speed of 12 r\/min, this takes 66 seconds.<\/p>\n<p>If the target output is 30 pallets per hour, each cycle has a budget of 120 seconds. After 66 seconds of wrapping, 54 seconds remain for infeed, stabilizer plate movement, film cut, and outfeed. If a second pass is added on the way down, the total time increases, potentially reducing the practical output to around 25 pallets per hour. These figures are arithmetic examples, not measured cycle times; actual performance depends on your specific configuration.<\/p>\n<h2>What safety standards apply?<\/h2>\n<p>The RAS100 design follows EN 415-6, the safety standard for pallet wrapping machines. Every line layout is risk-assessed using the ISO 12100 method. Operators must be kept clear of the sweeping arm, the moving carriage, and the descending stabilizer plate.<\/p>\n<p>Guard rails enclose the station around the conveyor, and a white anti-collision loop on the carriage halts the cycle upon contact. Certification of a delivered machine is confirmed in the project ordering agreement; the machine itself is not claimed to hold a standalone certificate.<\/p>\n<h2>When is a rotary arm better than a turntable?<\/h2>\n<p>A rotary arm is preferred for light, tall, or unstable loads that should not spin. It is also suitable for heavy loads that a turntable would have to carry. The stationary pallet method prevents shifting in delicate stacks, while the arm structure supports weight without rotating the base.<\/p>\n<h2>How do I get a real configuration?<\/h2>\n<p>A quotation for the RAS100 is built from site data, not from the standard table alone. An enquiry pack for the supplier should carry the following items:<\/p>\n<ol>\n<li>Pallet footprint and stack height.<\/li>\n<li>Description of the stack material and its stability.<\/li>\n<li>Target output per hour and per shift.<\/li>\n<li>Line conveyor height and flow direction.<\/li>\n<li>Requirement for a top sheet cover (yes or no).<\/li>\n<li>Site voltage and compressed air availability.<\/li>\n\n<p>With that pack in hand the configuration is priced against real pallets, and anything left open comes back as a question rather than an assumption. We reply with a proposal after we confirm the details.<\/p>\n<h2>Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Rotary-arm-wrapping-machine\/Rotary-stretch-wrapper-RAS100.html\">Automatic rotary arm stretch wrapper RAS100<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/fhope-r100-rotary-arm-pallet-wrapper-with-film-cutter\/\">FHOPE-R100 rotary arm pallet wrapper with film cutter<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/height-pallet-packing-machine-with-top-press-device\/\">Height pallet packing machine with top press device<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/r100-rotary-arm-pallet-wrapping-machine\/\">R100 rotary arm pallet wrapping machine<\/a><\/li>\n<\/ul><\/ol><\/ol>","protected":false},"excerpt":{"rendered":"<p>A rotate arm stretch wrapping machine secures unstable or tall pallet loads by keeping the pallet stationary while a rotating arm wraps the film, preventing the top layers from shifting outward.
