What follows are extracts from the transcript of our conversation.<\/span><\/p>\n<p><!--more--><\/p>\n<h2>What is the Primary Reason Case Erectors Jam?<\/h2>\n<p><span style=\"font-weight: 400;\">There\u2019s no simple answer to that question. But, basically, they jam because something bad happens during the case erecting cycle. Think of it like this: \u00a0like a butterfly, a case goes through a kind of metamorphous. It starts out as a blank (also called a knockdown) which is a flat, die-cut piece of corrugated material and emerges from a case erector as a fully formed, bottom sealed case ready for use.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The case erector\u2019s part of this metamorphosis is to take the blank, erect it (form it), and seal the bottom flaps (with either tape or hot melt adhesive) of the emerging case. Properly done, the newly erected case is \u201csquare\u201d \u2013 all corner angles are 90 degrees \u2013 and the case is ready to do the job its designers intended: \u00a0be easy to pack and stack and provide maximum protection for its contents. <\/span><\/p>\n<p><span style=\"font-weight: 400;\"><img decoding=\"async\" style=\"margin: 0px 0px 10px 10px; float: right;\" title=\"case-erectors-1.png\" src=\"https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png\" sizes=\"(max-width: 320px) 100vw, 320px\" srcset=\"https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 160w, https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 320w, https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 480w, https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 640w, https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 800w, https:\/\/lantech.com\/wp-content\/uploads\/2020\/10\/case-erectors-1.png 960w\" alt=\"case-erectors-1.png\" width=\"320\" data-constrained=\"true\" \/>This is a little trickier than it might seem at first blush. Lots of things have to happen in sequence and on time. For example,<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The blank must be loaded into the case erector\u2019s magazine.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The blank must transfer from the magazine to the forming section.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The blank must be opened (formed) and squared.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The bottom flaps must be folded.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The bottom of the case must be sealed.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">So anytime a blank moves or makes a transition to another section of the case erector, there\u2019s the potential for that \u201csomething bad\u201d thing to happen that might cause the machine to jam.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-weight: 400;\">The best case erectors, though, are designed to manage these transition points and overcome the risks associated with them. Top performing case erectors, for example, use powered infeed belts in their magazines to precisely control the movement of the blanks as they move to the forming section. This overcomes the variability of unpowered, gravity-fed magazines that have little or no control over the blank and consequently are much more likely to jam.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Top product development teams also pay careful attention to the design and operation of the blank separation mechanism to ensure that only one blank at a time is released to the forming section. Poor designs in this critical area are notorious for causing jams.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The actual transfer of the blank to the forming section is a transition that\u2019s also high risk. Not only must the blank separate cleanly from the magazine, but it must also open correctly so the adjacent sides are perpendicular and the opposite sides are parallel. The best case erectors do this by using a \u201cvacuum pick-up frame.\u201d <\/span><\/p>\n<p><span style=\"font-weight: 400;\">This device has adjustable vacuum cups that firmly hold two panels of the blank and the frame itself forces the blank to open into a correctly formed square case. Pick-up frames are particularly effective in overcoming minor manufacturing variations in blanks \u2013 they force the blank to open correctly. This is another example of how proper attention to and management of critical transition points reduce the potential for jams to happen. \u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Once the case is square, that \u201csquareness\u201d needs to be locked-in by folding its bottom flaps. Trying to do this while the case is moving is hard and often results in a jam. It\u2019s best to use a machine that folds the bottom flaps while the case is stationary. This is another example of maintaining control of the case can reduce the potential for jams and how a square case is delivered to the sealing section \u2013 another critical transition point.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sealing sections consist of a pair of belts that hold the case\u2019s long sides (its length) and convey it over a tape dispenser or hot melt glue nozzles that seal its bottom flaps. Minor differences in case widths caused by manufacturing variations in the blanks can result in jams. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the case is too wide or too narrow when it reaches the side belts, a jam is likely unless precautions are taken. The better machines deal with these issues by \u201cspring loading\u201d the side belts so they can move closer together or farther apart to deal with either condition yet still hold the case securely enough to move through the section and be effectively sealed.<\/span><\/p>\n<h2>A Brief Note About Case Quality<\/h2>\n<p><span style=\"font-weight: 400;\">There are a host of issues surrounding corrugated case quality. But for the purpose of this conversation, it\u2019s worth noting that there\u2019s a trend today toward using thinner board and more recycled content.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These cases challenge the capabilities of many case erectors and, in many instances, result in unacceptable and unnecessary levels of downtime. In today\u2019s environment, the quality of the case erector is more important than ever in helping companies achieve their cost reduction and sustainability goals.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"> Any reputable case erector manufacturer will be happy to test your cases on their machines and work with you to ensure the benefits of your case erector are fully realized.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Check out these related posts:<\/span><\/h2>\n<ul>\n<li><span style=\"font-weight: 400;\"><a class=\"tooltip-theme-arrows tooltip-target
