Unformatted text preview: 19. 1 Unit 19 - Packaging Machinery There are several categories of packaging machinery. Some of these we have already discussed, such as how cans and bottles are manufactured. These are termed “converting” operations, since they transform (convert) the packaging materials into the packages themselves. Printing is also considered a converting operation, and we will look at it a bit more in its unit. In this unit, we will primarily discuss the other categories of packaging machinery, those machines that make up the packaging line that set up, fill, close, and seal packages, or assemble completed packages into secondary or tertiary packages, handle the finished packages, palletize them (put them on pallets), etc. 19.1 Types of Packaging Machines Packaging machines of various types might be found in any of the following (and many other) situations: A high speed metal can line for beer or soft drinks running at speeds as high as 2,500 packages per minute. A medium speed glass or plastic container liquid filling line for milk, motor oil, or pancake syrup, running at speeds from 250 to 600 containers per minute. A pharmaceutical line running at 100 to 180 packages per minute. A dry cereal bag-in-box packaging line running at 250 to 750 completed packages per minute. A small company or private individual owned line packaging candy, specialty bread, honey, or jams and jellies, running at 40 to 150 packages per minute. An automated potato chip filling operation running at 150 bags per minute. A modern packaging line can be an expensive operation. At a recent seminar, speakers discussing lines for filling metal cans with carbonated beverages suggested that planning should start with the assumption that at least $25 million would be involved. The funds would be used to obtain necessary permits and licenses, to build the facility, to purchase and install equipment, to train operators, and all for other activities needed to put the system into operation. This is called a turn-key project when a construction or consulting company takes on the entire project and hands over a key to the door when the system is complete and ready to run. A high speed can filling line is probably the most expensive type of packaging facility. Others, which operate more slowly or which use fewer and less expensive machinery, naturally have lower overall costs. There are several types of machines that are used to perform the various packaging line functions. In parts of this unit, the machine types in the following list will be described and briefly discussed. The discussion will take place within the context of a "typical" beverage packaging line, as shown in the system diagram. The system plan shows how the various machines are set into a sequential arrangement. Empty containers are fed in at the upstream end of the line and then passed downstream from machine to machine to have various operations performed until shipping containers...
