Description
FIELD OF INVENTION
[0001] The present invention relates to an arrangement for
effective handling of sheet material, such as banknotes or
transferred sheet printed messages, wherein the arrangement
includes sheet bundling means, a store of bundle enveloping or
packaging material, means for enveloping a bundle of sheet material
with enveloping material taken from said store, said store
including two mutually co-acting rolls of enveloping material, and
further includes processor for co-ordinating and controlling the
mutual co-action of the various units in the arrangement in
accordance with a predetermined pattern.
DESCRIPTION OF THE BACKGROUND ART
[0002] Arrangements of this kind are known to the art; see for
instance U.S. Pat. No. 5,031,379. Although these arrangements have
functioned well per se and fulfil a need, more and more
sophisticated requirements have been expressed as the use of and
the interest in such arrangements has grown. For instance, it is
desired to know
[0003] when there is no more packaging or enveloping material left
in the store; how much material is left in the store; the number of
envelopes that can be produced from the remaining supply of
material;
[0004] whether or not a collected sheet bundle has been enveloped
in the material and correctly welded-off from the store of
enveloping material;
[0005] whether or not a newly inserted store of enveloping material
is positioned correctly; and
[0006] the type of enveloping material that is stored in the
arrangement at that particular time.
[0007] Issues of this nature can be dealt with easily and
positively by arrangements constructed in accordance with the
present invention.
SUMMARY OF THE INVENTION
[0008] In accordance with the present invention the store of
enveloping material in an arrangement of the aforesaid kind is
provided with pulse generating elements and pulse reading elements
are disposed on a fixed body of the arrangement in close connection
with said pulse generating elements on the store, said pulse
reading elements functioning to read pulses that are generated in
response to roll movement and to transfer these pulses to the
arrangement processor. These and other characteristic features of
the invention will be apparent from the accompanying claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The invention will now be described in more detail with
reference to the schematic drawings, in which
[0010] FIG. 1 illustrates an arrangement according to U.S. Pat. No.
5,031,379;
[0011] FIG. 2 is a sectional view of an enveloping material
carrying roller and shows end walls and pulse generating elements;
and
[0012] FIG. 3 is a front view of an end wall that carries pulse
generating and pulse reading elements.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0013] The known arrangement shown in FIG. 1 includes a
telefax-type receiver 10 which includes signal receiving means and
a printer 43 for printing of received messages on sheets taken from
a sheet store 41, and a closed casing 11 which as the sheets are
printed, functions to bundle together printed sheets that have
passed through the printer 43. Also included is a store (rolls) 25,
27 of enveloping material 26 and 28 in which the collected bundles
of sheets are enveloped, or enclosed. The bundles are enclosed with
the aid of first joining elements 30 which function to produce
vertical joins (parallel with the plane of the paper); second
joining elements 32-34 which function to produce horizontal joins
(perpendicular to the plane of the paper); and transport rollers 35
for transporting the enclosed bundle of sheets to a lockable box
14.
[0014] FIG. 2 illustrates a sub-store 25 containing enveloping or
enclosing material (plastic) 26. The material is rolled-up on a
cylindrical bobbin 251 which has an end wall 252, 253 fitted on
respective ends thereof. Each of the end walls has pulse generating
means, namely an outer clock pulse generating element 2521, 2531
close to the periphery of respective end walls, and an inner
information generating means 2522, 2532 closer to the centre of
respective end walls.
[0015] Mounted on the fixed frame 20 of the sheet enclosing device,
in close connection with the pulse generating elements 2521, 2522
on the left end wall 252 of the sub-store 25 is a pulse reading
element 29 which functions to read pulses (clock pulses,
information pulses) delivered in response to rotational movement of
the sub-store 25, and to send these pulses to a processor that is
adapted particularly for co-ordinating and controlling the mutual
co-action of the various units in the arrangement.
[0016] The pulse reading element 29 is comprised of an outer clock
pulse detecting sub-element 291 and an inner information reading
sub-element 292. Each sub-element includes a "fork" which embraces
a pulse generating element on the end wall when a supply of
enveloping material is placed correctly in the arrangement; in
other words, respective sub-elements will constantly read-off the
associated pulse generating element as the sub-store 25
rotates.
[0017] FIG. 3 illustrates the sub-store end wall 252 with said
outer pulse generating element 2521, the inner information
generating element 2522, and the pulse reading element 29 with its
two fork-like sub-elements 291 for the element 2521 and the
sub-element 292 for the element 2522.
[0018] As will be seen, the element 2521 has eight (8) teeth and
eight (8) interspaces over a peripheral area of 90 degrees, whereas
the element 2522 has, in the illustrated case, only one tooth and
one interspace on the same length of arc.
[0019] Located between two side walls are two guide struts 36, 37
which function partly to guide a roll when positioning the roll in
place in the arrangement, and partly to provide a safe support for
the roll during operation of the arrangement. These guide struts
ensure that the pulse generating elements 2521, 2522 obtain a
correct free position in relation to the pulse reading sub-elements
291, 292. These elements include, in a known manner, light emitting
elements and light sensitive elements on each side of the arcuate
elements 2521, 2522.
[0020] Pulses outputted from the outer pulse generating element
inform that the roll rotates. A comparison between the pulses from
outer and the inner pulse generating elements indicates the
direction in which the roll rotates, and pulses outputted by inner
pulse generating element give, for example, information relating to
the type of enveloping material in the store, the quality of said
material, its thickness, etc.
[0021] The arrangement of pulse generating elements on the rolls
provides further possibilities of steering/controlling the
arrangement. In the production of rolls of enveloping or encasing
material, this control facility is achieved by first winding the
material through a number of turns in one direction and then
winding the remainder of the material on the roll or bobbin in the
reverse direction. This gives the advantage that as the enveloping
material is taken of the rolls, the two rolls will rotate in given
(mutually opposite) directions, which are sensed by the pulse
sensing element. When unwinding of the material has reached the
point at which the winding-on direction was reversed, the rolls
will stand still during continued unwinding of the material by
virtue of the material sliding off from the underlying turn,
wherewith the rolls will rotate in another direction until there is
no material left. The sequence comprising rotation in one
direction--stationary rolls--rotation in the reverse direction is
sensed by he element 29, which thereby causes pre-determined
signals to be sent to the processor and also certain
process/signals in the arrangement via the processor.
[0022] The co-ordinating and controlling processor described above
is indicated at 15 in FIG. 1.
[0023] It will be understood that the invention is not limited to
the described exemplifying embodiment entailing the transfer of
sheet-printed messages. For instance, the invention can also be
applied in connection with the handling of banknotes where bundles
of banknotes are enveloped, encased or likewise packaged. Each
bundle may contain 100 banknotes or the bundles may alternatively
contain mutually different pre-determined numbers of banknotes. In
this case, a given number of banknotes are dispensed singly from a
store of banknotes and gathered into a bundle, which is then
encased in enveloping material taken from the store of enveloping
material (plastic) by means provided downstream to this end, all in
accordance with what has been described above.
