supporting the trailing edge of the stack of cartons, a
carton separator 18 for separating the lowermost carton
This invention relates in general to an apparatus for 10
feeding cartons from a magazine, and more particularly
to an apparatus for successively feeding cartons one at
a time from the bottom of a stack of cartons held in a
magazine.
’
Heretofore, many apparatuses for feeding cartons in
?attened condition from a magazine have been developed,
all of which have had de?ciencies and which are limited
to ‘operational speeds.
The carton feeding apparatus of the present invention
is capable of high speed operation necessitated by new
and advanced methods of manufacture, and also over
comes many of the dif?culties heretofore encountered in
such magazine feeding mechanisms.
The apparatus of the present invention will be described
in connection with the feeding of ?attened cartons from
a magazine, but it should be understood that the inven
tion is just as applicable for the feeding of ?attened sleeves
from a magazine. Thus, use of the word “carton” is
meant to embody sleeves or other equivalent structures.
It is therefore an object of this invention to provide
an improved apparatus for feeding cartons one at a time
from a magazine under high speed conditions, and in
timed sequence.
A further object of the present invention is in the
from the next lowermost carton and supporting the next
lowermost carton and the stack, a carton vsupporting
means 19 for selectively supporting the lowermost carton
and the stack at the leading edge thereof during part
of the cycle of operation, and means for engaging the
trailing edges of a plurality of the lowermost cartons to
arrange them in stepped relationship and thereby func
tion as a bumper ‘or locator as identi?ed by the numeral
20.
A carton 21, FIG. 2, is exemplary -of the type that
may be arranged in the stack '16 and fed from the bottom
of the magazine. However, it should be appreciated that
other types of car-tons or sleeves may also be handled by
the magazine and feeding apparatus of this invention.
The magazine 15 includes a front wall or guide means
22, a rear wall or guide means 23, and opposed side walls
or guide means 24 and 25. The lower portions of the
walls or guide means are upstanding and substantially
vertical, while the upper portions are slanted or inclined as
seen particularly in FIGS. 1 and 4. In all instances, the
cartons are maintained in a substantially horizontal posi
tion. An extension may be employed for the magazine
which would project somewhat horizontally from the
upper ends of the slanted portions for carrying a supply
of cartons that are to be fed to the magazine. The maga

and 11, the wedge 61 has completely separated the lower
most carton 21a from the next lowermost carton 21b and
has forced the lowermost carton onto the moving belt 53
while still functioning to support the next lowermost
carton 21b in the magazine and behind the lower end of
the front wall ?ngers 22a ‘and 22b. And the segment
disks 66 have rotated to drop the remaining portions of
the lowermost carton 21a onto the belt 53 so that the
lowermost carton can be delivered beneath the wedge 61
and the lower end of the front wall 22 and out of the
magazine. In order to enhance the frictional contact
between the lowermost carton 21a and the belt 53, and
assure positive feeding of the carton from the magazine, a
soft rubber roller 69 is employed beneath the belt and in
alignment with the movable Wedge 61. This roller is
mounted on the shaft 45 and rotatable therewith. The
wedge 61 remains in the position shown in FIGS. 10 and
11 to support the next lowermost carton 21b until the
segmental supporting disks 66 have rotated so that the
high point thereof can again engage the next lowermost
carton as in shown in FIGS. 12 and 13. After the wedge
reaches its extreme retracted position, it will again‘then
be advanced inwardly to separate the next lowermost
carton from the bottom of the stack and enable it to be
fed therefrom. During the movements of the wedge and
segmental disks, the bumper 24) will be operating to en
hance the arranging of the lowermost cartons in stepped
relationship so that they can be easily ‘separated by the

alignment with the auxiliary belts 54 and 55 to apply
pressure thereagainst and de?ne holddown rollers to hold
a carton against these belts as the carton is being removed
from the magazine. The frictional contact with these
belts is thereby enhanced. Actually the carton is driven
between the belts and these rollers after it has left the
magazine and then these belts also aid in feeding the 60
carton onward. Similarly, a spring or gravity biased hold
down roller 75 is provided ahead of the magazine and
in alignment with the center belt 53 to give added fricion
