Appeal No. 2002-2230
Application 09/295,547
According to Reuteler (see columns 3 through 5; and column 10,
lines 28 through 42), this arrangement affords a high degree of
flexibility in adapting the packaging apparatus for carton blanks
of various sizes and shapes. As described in more detail in the
reference,
[i]n conventional fashion, packaging machine 7
will be provided with a control processor 61 (FIG. 4),
not illustrated, for automatically controlling the
operation of carton feed opening wheel assembly 5, as
well as the additional components of the packaging
machine. It is anticipated that the control processor
will be an IBM PC compatible computer having an
internal computer-readable medium with a series of
preprogrammed electronic cam data profiles 62 (FIGS. 4,
6) stored therein, as well as the control program
operating packaging machine 7, and/or that the control
processor will be provided with a device for reading a
computer-readable medium, for example, a floppy disk
drive or a CD ROM drive, so that it may receive the
appropriate preprogrammed data and control programming
operations to operate carton feed opening wheel
assembly 5 in conjunction with packaging machine 7.
Thus, in FIG. 6 three different illustrative electronic
cam profiles 62A, 62B, and 62C are shown, each of the
cam profiles being stored as preprogrammed data within
the control processor and the computer-readable media
made available to the control processor.
In FIG. 6 the vertical axis of the graph shows the
rotational angle of carton opening wheel 30 during a
single carton opening cycle, as shown in FIGS. 5A-5E.
The operation of carton feed opening wheel assembly 5
for one carton opening cycle with respect to the
rotational angle of carton opening wheel 30 is shown
along the bottom horizontal axis of FIG. 6.
The three illustrative cam profiles, denoted by
the reference characters 62A, 62B, 62C, serve to show
the control methodology used in operating servomotor 47
for rotating wheel frame 34 about central longitudinal
shaft 35 [column 9, lines 32 through 64].
