ment utilizes an approximately 90° cone and a 45° angle
of inclination for the axis of rotation of the cone, it may
be feasible in various instances to modify these'angles
somewhat in order to accommodate different desired
input angles and output angles for the bobbins to be
transferred. The receiving and/or discharge positions
may be varied by changing either or both of the effective
degree of taper of the cone and the degree of inclination
of the cone axis. Thus, if one desired to transfer bobbins
from a position where they were inclined to the hori
zontal to a position where they would be substantially
vertical, one might employ a transfer cone of less than
90° at the apex and an angle of inclination to the hori
zontal of greater than 45°. Such is not desirable in the
present instance, however, for this might result in an 30
undesirable skewing and di?iculty of feeding of the bob:
bins in the reserve chute, although in some instances this
might be tolerated.
-
The bobbin receiving belt 17 is preferably formed with
bobbin receiving and holding members disposed thereon
at spaced apart intervals in order to provide for retaining
of the bobbins in spaced apart upstanding positions along
‘ the length of the belt, thereby providing a fully posi
tioned and easily handled source of oriented bobbins
which may be picked up as by a simultaneous multiple
position type dolfer carrier. In the instant example the
bobbin receiving and holding members take the form of
drive motor M which serves to impart rotation, as
through a conventional mechanical gearing or other de
sired connection, generally indicated at 33, to both of the
cone supporting and drive shaft 23 and the drive roll 31
for the bobbin receiving belt 17. In order to further fa
cilitate the positive synchronism of the belt 17 with the
transfer cone v15 the belt may be provided with cleats
17b or the like on its inner surface which engage with
corresponding grooves 31:: formed on the peripheral sur
face of the drive roll 31.
In order to insure the supplying of a bobbin B to
each of the succeeding pegs 17a on the peg belt 17 as
they pass the cone discharge and seating zone the re
serve chute 13 is provided with a low reserve stop
motion switch 35 for the drive motor M. This low re
serve stop-motion switch 35 may take the form of it nor
mally closed Micro-switch or other suitable switch dis
posed on the side wall of the vertical trough of the
chute, and having a feeler ?nger 35a extending into the
bobbin passage within the chute for sensing the presence
of bobbins. By disposing this switch 35 at a suitable
height on the side Wall of the vertical reserve and dis
charge trough portion of the chute, as for instance 3 or
4 bobbins’ height above the discharge end, the power
circuit to the motor'M will be broken and the motor
will stop prior to any failure of supply of bobbins to the
transfer cone 15 as the cone moves past the reserve chute
discharge end, thus insuring that the transfer cone will
not be rotated in the absence of a supply bobbin for each
belt 17.' These pegs may extend along the entire length,
or less, of the belt if desired. However, it will be noted 45 next succeeding recess to be loaded.
