Brackett Edition Master Machine End Sheet Tipping and Taping Machine
Tipping and Taping Machine Description
Feed pockets: The EM-IV features two automatic feed pockets with sucker assemblies; one for end sheets and one for signatures. The automatic feed pocket’s unique design allows for easy adjustment of back plates, angle guides and crowder assembly height. In addition, both work support tracks are adjustable up or down thereby permitting the EM to handle more product variations. Feeder assemblies: Dual hoppers are designed around four vertical linear servo motor robotic shuttle systems with pneumatically driven vacuum bars for precise picking and controlled placement of a wide variety of material mediums and size ranges of end sheets and signatures. The vertical servo units are digitally tuned and monitored by a PLC to provide optimum product registration and control via a “high resolution” digital encoder.
Mis-feed & double detection: Is designed for first chance detection in the gripper assembly and second chance detection in the pre-head belt area. COMPRESSION HEAD BELT ASSEMBLY Compression head belts: The flight chain assembly delivers the endsheets and signature combinations into a power driven compression head belt section, which grips the preregistered units and conveys them through tipping and taping operations. Tipping: The EM-IV features a pressurized cold glue extruder tipping system with superior, airactuated controls for precision start-stop glue application. An optional hot melt tipping system can be deployed. Hot melt glue pot: The 3.63 KG (8 pound) hot melt glue pot features operator friendly, state of the art digital controls, automatic start-up, seven day timer, digital temperature control readout and overheating protection. This is the same glue pot technology that is featured on the famous Brackett Circular Padding Machines, which have been in use worldwide for decades. Optional Cold Glue and Hot Animal, Glue Pots are also available. Tape application: To apply the adhesive, reinforcing tape is drawn over a roller immersed in hot melt glue. (Cold Glue & Hot Animal Glue Pots optional) Hot melt is recommended since it sets up quickly, needs no wiping, no skimming, and is easy to clean up. After applying the adhesive to the tape, the tape is pressed to the spine and formed by unpowered rollers, shoes and spring loaded wipers. Tape: A knife cuts the tape anywhere between the signatures with a simple rotary blade knife. Tape tails need to be removed in a separate operation. DELIVERY The EM-IV comes with a machine driven flat belt conveyor. The combined/tipped individual items are automatically laid separately on this conveyor.
