Abstract
Abstract A conveyor (13) has a rotary encoder (55A,55B) for measuring the amount of rotation of a driven sprocket (44A,44B) having an intermittently drivable chain (45A,45B) reeved therearound, and a processor for processing the measurement obtained by the encoder as operation support operating data corresponding to the amount of rotation of the driven sprocket. The processor determines a reference position of the chain in time series when the chain is moved a distance at a time by intermitting driving, computes the actual position of the chain corresponding to the reference position based on the measurement obtained by the encoder, and computes the deviation of the actual position of the chain from the reference position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
65 words
A conveyor comprising a drive sprocket, a driven
sprocket and an intermittently drivable chain reeved
around the sprockets, the conveyor being characterized
in that the conveyor comprises an instrument for
measuring the amount of rotation of the driven sprocket,
and a processor for processing the measurement obtained
by the instrument as operation support operating data
corresponding to the amount of rotation of the driven
sprocket.
Claim 2
Dependent Claim
75 words
A conveyor according to claim 1 wherein the
processor comprises setting means for determining a
reference position of the chain in time series when the
chain is moved a distance at a time by intermitting
driving, means for computing the actual position of the
chain corresponding to the reference position based on
the measurement obtained by the instrument, and means
for computing the deviation of the actual position of
the chain from the reference position.
Claim 3
Dependent Claim
80 words
A conveyor according to claim 1 wherein the
processor comprises setting means for determining a
reference halted position of the chain every time the
chain is moved a distance by intermitting driving during
one turn of movement, means for computing the actual
halted position of the chain corresponding to the
reference halted position based on the measurement
obtained by the instrument, and means for computing the
deviation of the actual halted position of the chain from
the reference halted position.
Claim 4
Dependent Claim
88 words
A conveyor comprising a pair of drive sprockets,
a pair of driven sprockets and a pair of intermittently
drivable chains each reeved around the drive sprocket
and the driven sprocket corresponding to the chain, the
conveyor being characterized in that the conveyor
comprises a first instrument for measuring the amount
of rotation of one of the driven sprockets, a second
instrument for'measuring the amount of rotation of the
other driven sprocket, and a processor for processing
the measurements obtained by the two instruments as
operation support operating data.
Claim 5
Dependent Claim
83 words
A conveyor according to claim 4 wherein the
processor comprises setting means for determining
reference halted positions of the respective chains
every time the chains are moved a distance by
intermitting driving during one turn of movement, means
for computing the actual halted position of each of the
chains corresponding to the reference halted position
of the chain based on the measurement obtained by the
corresponding instrument, and means for computing the
deviation of the actual halted position from the
reference halted position.
Claim 6
Dependent Claim
62 words
A conveyor according to any one of claims 1 to
5 wherein a plurality of container holders are attached
to the chain at a spacing corresponding to the distance
the chain is moved at a time by intermittent driving,
and the chain has a container transport path extending
successively via a group of devices including a filling
device and a sealing device.
