Abstract

Band saw (A, B, C) characterized by a belt chain conveyor system which transports, locks in place and symultaneously cuts tree trunks in a cutting part (B) into several logs. A conveyor belt (C) then transports an separates the logs according to dimensioner. Pieces which are too large are returned for further cutting.

Description

INVENTION DESCRIPTION
AUTOMATIC MULTI BAND SAW
iThis invention regards a multi
belt which simultaneously cuts
tree trunks into several logs:
Until now, saws were able to make
one cut at time, and thus the
process had to be repeted several
time to produce many logs.
This slows the production time.
This invention eliminates that
loinconvenience by speeding up the
process. Moreover, thanks to the
structure of the system, it is
safer for workers because they are
further from the cutting area. This
i5is possible thanks to the conveyor
belt. Workers load the trunks on
the belt and the chain system locks them in position for
cutting. Several belt saws then
2osimultaneously cut several logs
from one trunk. Another belt then
remove the logs and separate the
ones ready for use from the ones
that need addictional cutting.
^Figl shows a sectionalized frontal
view of the saw; Fig 2 is a side
view which clearly shows its three
main parts; Fig 3 shows the part A,
the loading system composed of a
^loading belt (Al) on which the
trunks are placed for cutting; a
system (A3) made up of wheels and
balances which block the trunk
until the cut area (B) ; Fig 4 shows
^the central part for cutting (B) :
a system with belt saws (Bl) supported by fly wheels (B2) : the
belt saw simultaneously cut the
trunks in several logs; the belt
oslide on guides (B5) at a specific
distance in order to obtain equal
logs of about 30 cm.; A system
realising the brake of the fly
wheels (B4) allows for the
^changing of the belts. The trunk,
divided in several logs by a
cutting plane (B8) falls down the
separator (BIO). Fig. 5 shows the
loading belt which carries and
.separates the logs according to
their dimensions . The details of
execution can change without to
get off the brevet of invention.
