DETAIL DESCRIPTION
The cast metal ribbon enters through a fixed entry
chute (1). The ribbon is dragged through the chute with
the help of a suction provided in the chute by means of a
blower (2). The ribbon is passed through a pair of support
rollers (3, 3') and a dancing roller (4) located between the
support rollers (3, 3').
A thickness measuring gauge (6) is located in the
path of the metal ribbon for monitoring the thickness of the
ribbon. A snubber roller assembly (30) is provided for
pressing the ribbon till it touches the spool. A brush assembly (31) is provided to catch the ribbon and maintain
a required tension in the ribbon. A detachable entry chute
(7) is provided through which the metal ribbon is passed to
a ribbon attaching station (15) at a first position (Pi)
provided with an empty spool on a winding mandril (1 ).
A hitting rod mechanism (9) is provided aligned to the
ribbon attaching station (15) to hit on the ribbon against
the empty spool on the winding mandril (19) so that the
ribbon gets attached to the spool and the extended portion
of the ribbon is cut out from the spool. Preferably the
surface of spool is provided with an adhesive tape so that
the ribbon is properly stuck to the spool when the liitting
rod mechanism hit on the ribbon against the spool. After
the hitting action the winding mandril start rotating and the
rotation of the spool is synchronized with the linear speed
at which the ribbon is advanced. Necessary loop correction
is achieved with the dancing roller (4) by means of a
pneumatic cylinder (5) to keep the ribbon at appropriate
tension. Then the mandril with the ribbon attached to the
winding spool is moved to the winding station (16) at the
second position (P2) and the empty spool on a winding mandril (21) is moved to the first position (Pi). Support
roller (10) is located between the first position (Pi) and
second position (P2) to support the ribbon. The cut portion
from the ribbon after the operation of the hitting
mechanism is sucked out through a delivery chute (11)
provided with a suction created by a blower (2 ). The
delivery chute (11) is provided with a pneumatic cylinder
(12) for its operation and the cut pieces are collected and
may be recycled.
When the winding spool is fully wound with metal
ribbon it is moved to the third position (P3) where a
mechanism (18, 25) for wound spool unloading and empty
spool loading is provided for removing the wound spool
and loading an empty spool on the mandril.
The mechanism for wound spool unloading and
empty spool loading comprises a pusher plate (18.1) with a
hydraulic pushing cylinder (18.3) to push the wound spool
from the mandril to a turn style (25) with operating means
(26) for receiving the wound spool, a hydraulic lifting cylinder (18.2) for lifting the pusher plate and a base stand
(18.4). Hydraulic cylinders (14, 22, 23, 24) are provided
on the spool changing platform for moving the spool on
the winding mandrils from the first position (Pi) to second
position (P ), then to the third position (P ) and to the
fourth positions (P4). The empty spool at the first position
(Pi) is moved to the second position (P ) after the ribbon is
attached to the spool. The ribbon is wound on the spool at
the second position (P2) and moved to the third position
The wound spool at the third position (P3) is unloaded
from the mandril and an empty spool is loaded on the
mandril and moved to the fourth position (P4) where it
remains till the spool in the second position (P ) is fully
wound and the hitting rod mechanism (9) is operated to cut
the ribbon from the spool in the second position (P2) and to
attach ribbon to the spool in the first position (Pi). The
mandril with wound spool in the second position (P2) is
moved to the third position (P3) and the mandril with the
empty spool and attached to the ribbon is moved to the second position (P ). The mandril with the empty spool in
the fourth position (P4) is now moved to the first position
(Pi) till the spool in the second position is fully wound.
Meanwhile the mandril with the wound spool in the third
position (P3) is unloaded, an empty spool is loaded on the
mandril and moved to the fourth position (P4) as a stand by
mandril with spool. The tips of the mandrils (19, 20, 21)
are preferably collapsible in order to make loading and
unloading of spools easy.
The hitting rod mechanism (9) comprises a hitting rod
operating lever (9.1), a lever actuating rod (9.2) and an
electromagnet (9.3) for operating the lever actuating rod
(9.2). Movable guides (27) and fixed guides (28) are
provided on the spool changing platform for smooth
movement of the winding mandrils with spools, along the
prescribed paths.
The movable guides (29, 29') are operated by
hydraulic cylinders (13, 13") and the spooling mechanism
is provided with a hydraulic cylinder (14) for moving the mandril (19) to the second position (P2) after catching the
ribbon at first position (Pi). The pneumatic cylinder with
ribbon support roller (10) brings the ribbon down for
attaching the ribbon, when the winding is completed at the
second position (P2). The sequential operation of the
motion of the winding mandrils with spools and operation
of the liitting mechanism are controlled by a programmed
processor. The timings of the operation of the pneumatic
cylinders and hydraulic cylinders are decided by the
program.
The machine according to the invention can be used
for coiling ribbon material of any type wherein the ribbon
is produced continuously and is required to be made in the
form of coil. The machine has been effectively tried in the
production of coils of amorphous magnetic ribbon used in
making electrical transformers and rotating machinery.
