Description
- The present invention relates to a drive system in a packaging machine.
- In a packaging machine for applying cartons to a plurality of articles, such as a paperboard sleeve to a plurality of bottles, there are a number of functional parts which need to be driven at precise speeds and with precise synchronisation. If these are not achieved then the machine will not run smoothly or efficiently. The matter is complicated by the need to change the multipacks produced, for example, from 2 X 2 packs to 2 X 4 packs. The same number of cans may pass through the machine but half the number of carton blanks will need to be "picked" from the carton magazine. Certain parts of the machine will, therefore, need to be run at different speeds to other parts.
- GB 797 148 A discloses a drive system in accordance with the preamble of appended claim 1.
- According to the present invention there is provided a drive system in a packaging machine for applying cartons to a plurality of articles, the drive system comprising first and second drive motors, characterized by, the second motor taking a speed reference from the first motor, first and second main shafts for respective drive motors, a number of first power take-offs from the first main shaft and a number of second power take-offs from the second main shaft, the first power take-offs being connected to product pitched functions of the packaging machine and the second power take-offs being connected to non-pitched functions of the packaging machine.
- Preferably the product pitched functions may include infeed starwheels, a carton pick mechanism, a folding mechanism for the carton sides, flap wheels for initiating a locking arrangement on the cartons. Also the non-pitched functions may include a transport conveyor for the articles, a carton transport mechanism, an overhead boom for engaging an upper portion of the carton being applied. An unpitched tightening mechanism for tightening the carton around the articles may also be a non-pitched machine function but could also be pitched.
- In alternative embodiments there may be further servo drive motors associated with further main shafts and take-offs, which further drive motors take speed references from the first or second motors.
- An embodiment of the present invention will now be described in more detail. The description makes reference to the accompanying drawings in which:
- Figure 1 is a skeleton perspective view from one side of a drive system according to the present invention,
- Figure 2 is a simplified view from the other side of a machine incorporating the drive arrangement of figure 1, and
- Figure 3 is a simplified plan view of the machine shown in figure 2.
-
- In the figures there is shown a
packaging machine 10 which in this embodiment is designed for applying and securing a sleeve type paperboard wrap around a plurality of articles such as bottles or cans. Other articles could be wrapped and the type of carton being applied could be different. - The
packaging machine 10 incorporates a drive system 11 which comprises first andsecond drive motors main shafts 14, 15. Thesecond drive 13 takes a speed reference from thefirst drive 12. Coupled to the first and secondmain shafts 14, 15 to be driven thereby are first and second sets of power take-offs respective gearboxes offs packaging machine 10 using a combination of shafts, belts, pulleys, further gearboxes and other suitable components. In figure 1, the second drive shaft and take-offs are shown blacked in. - A number of said working sections perform pitched functions which depend on the particular product/package configuration being run on the
machine 10 at any one time and on the speed required in packs per minute. These first working sections will all be driven by the first power take-offs 16 and the settings for these first working sections will be stored for each package/speed combination in a computer management system. - The first working sections of the illustrated
machine 10 include infeedstarwheels 20 which meter the incoming product, a second set ofstarwheels 21, acarton pick mechanism 22 which takes a carton from a magazine 23 for each group of products to be wrapped, a folding mechanism in the form of rotatingarms 24 for folding down the sides of each carton and also aflap folding section 25 which activates flap formations which constitute seat areas for heel portions of the products. - In contrast, a number of said working sections perform non-pitched functions which run at the specific linear speed of the
machine 10 which is the product of the package length and the machine speed in packs per minute. For each specific product/package configuration combination and number of packs per minute permutation stored in the computer management system there is a corresponding speed reference given to thesecond drive 13 such that all of the second working sections driven by thesecond drive 13 run at the correct speed as of course do all of the first working sections driven by thefirst drive 12. - The second working sections of the illustrated
machine 10 include a product transport conveyor 30 for moving the products through the machine overbase plate 35, acarton transport mechanism 31 for moving the carton through at least a portion of the machine, anoverhead boom section 32 which in this arrangement holds the carton against the products as they move through part of themachine 10 and a tightening/locking section 33 which tightens the carton around the products and activates interengaging locking formations on the carton. Sometimes this tightening/locking section 33 could in fact be product pitched depending on its actual construction. - It will of course be appreciated that other functions could run off either the first or
second drive shafts 14, 15 and some of those specified above may not be required in certain machine configurations. Also further drives and associated power take-offs could be provided, each taking a speed reference from the first or second drives.
