Field of the Invention
This invention relates to a high capacity continuous rotary packaging machine
and in particular, is used for packaging all granules, spices, washing powder,
tobacco powder like tobacco, zafrani zarda and khaini etc. More particularly,
this present invention relates to a continuous rotary packaging machine for
packaging articles of uniform size. Furthermore, this invention also relates to
a continuous rotary packaging machine in which the web with the pocket
containing the tablet or other article is then immediately positioned against the
other web at the nip of the laminating rolls and the two webs are caused to
adhere by pressure, and heat or the application of adhesive to one of the webs.
Further more this invention also relates to the machine in which the accurate
position of an upper sealing strip and a bottom sealing strip can be ensured
effectively, package pockets are prevented from being broken, and packaging
speed is greatly enhanced.
Background of the invention and the related Prior Art
As disclosed for example in Japanese Patent Publication Tokkai 10-7102, a
packaging machine of this type is typically adapted to bend an elongated bag-
2
making material (the "ftlm") by wrapping it around a tubular chute, to make it
into a tubular fonn by sealing its side edges together longitudinally, to
thereafter seal it and cut it transversely at specified intervals to continuously
fonn bags, and to drop articles to be packaged into the bags through the chute
while these bags are being fonned. The transverse sealing of the tubularly
fonned film is usually carried out by clamping it by a device for thennal
sealing, and the ftlm is separated at the sealed positions to be made into
individual packaged bags. Thus, the sealing must be effected during time
intervals between periods during which articles are dropped through the chute.
The current tendency in the packaging technology is to shorten the intervals at
which the articles to be packaged are dropped in successive batches so as to
improve the productivity. Although the intervals are shortened, there will be
enough space oftime left between the dropping of one batch to that of the next
if articles in each batch drop closely together and the sealing device can be
operated to clamp the film during such a space of time. In reality, however,
articles which are dropped together as a batch become dispersed while
undergoing a free fall inside the chute. As a result, it is likely that some of the
articles are caught when the sealing device clamps the ftlm transversely.

Wraps and prefonned bags are considered to be the traditional packaging
methods in the present packaging industIy. Wrapping involves the utilization of
a sheet of flexible material such as paper, cellophane, film, foil, or a laminated
film. Generally, the sheet is fed from a supply roll and folded around the
product to be packaged. Traditionally, wraps have been developed for specific
products in conjunction with specific types of equipment and systems.
Examples of products which have been packaged with the above method
include bread, candy and cigarettes.
Prefonned bags are also an old and well known fonn ofpackaging which were
originally made by hand to provide convenience in handling, fuling, and
closing. The materials used for prefonned bags include paper, cellophane,
polyethylene, foiL and laminates of these materials. The introduction of plastic
materials to this art has assisted in sustaining its popularity because of the
advances made in the technology and graphics, especially the transparency
enclosing systems which may be utilized. Products such as flour, sugar, and
produce have been typically packaged with this method.
The fonn/fill/seal pouch tyPe of flexible packaging is considered to be an
extension of the prefonned bag art. The significant difference over the
prefonned bag is that the fonn/ful/seal pouch structure may be continuously
4
fonned from supply of web material which can be fIlled and heat-sealed by
high-speed automated machines. Thus, a single machine may readily comprise
an entire and complete packaging line.
The art of continuously forming packages from flexible sheet material includes
methods and apparatus in the following genernl categories: wraps, prefonned
bags, and fonn/fill/seal pouches. In all ofthe above categories, the packages are
fonned from flexible sheet materials, such as, for example; paper, cellophane,
plastic fIlms, aluminum foil, or a combination of the above. It will be
appreciated that such packages have the inherent characteristics of being light
in weight; space saving; relatively low cost; adaptable to various production,
distribution, and retailing techniques; and functional for various end uses and
ultimate disposal.
The document TW201144160 describes a continuous rotary filling and
packaging machine which places a shaped lid P onto a container body Band
heat-seals it to produce a sealed container, equipped with a sealing device
which greatly reduces the occurrence of imperfectly mounted lids caused by the
lid not being properly mounted onto the container body. The continuous rotary
filling and packaging machine places a shaped lid onto the container body, then
mounts the shaped lid to the container body ultrasonically to produce a sealed
5
container. The continuous rotaty filling and packaging machine consists of a lid
detector positioned downstream of a lid feed unit, a means for raising and
lowering consisting of a cam mechanism which raises and lowers a container
platfonn disposed such that the top of the container body and the shaped lid on
the top dead centre of the container platform are pressed against the operating
surface of the ultrasonic horn, and an ultrasonic sealing device provided with a
control mechanism which does not raise the container platform to said top dead
centre position if it judges the container body to have no lid or an inconectly
mounted lid.
According to the document JP2009023697 the invention relates to increase
process capacity without breaking an item to be filled in filling the item to be
filled such as potato chips using a rotary type bagging and packaging machine.
The bagging and packaging machine has a moving atm which is moved
vertically by the move of a drive lever on an intennittently rotating table
conesponding to each gripper pair . Each arm is provided with a hopper atId a
chute. The ann is moved downward and the bottom end of the hopper is
inserted in a bag opening when the lever is moved down by the return rotation
of an annular cam and then the ann is stopped by a stopper. When the lever
moves down further more, a moving lever moves to pull a rod for tilting the
chute for fornling the sanle in an introduction posture with a lower outside end
6
and a higher inside end. A.n item received in the chute is slidingly dropped into
the hopper.
The present dual chamber sachet overcomes the problem of non-unifonn
dispensing when the sidewalk ofthe sachet are depressed. Through the use of a
relatively thin intennediate divider wall, rounded comer edges at the lower end
of each chamber ofthe sachet, tapered side edges up to the exit channel of each
chamber of the sachet, and a relatively wide dispensing opening unifonn
dispensing can be achieved. This structure prevents the downward flow of
substances in each chamber during dispensing. The substances are directed
upwardly by the rounded lower comers of the sachet, the tapered upper walls
and the wide dispensing opening. This relatively wide dispensing opening
minimizes the back pressure caused by the substances flowing to a dispensing
exit of a width less than that of the product chambers has been described in
INIPCT/2002/0 1071/DEL.
The document 5131MUM12006 describes a gas-fIlled sachet containing an
extrudable composition, said composition comprising plurality of distinct
phases that are not separated by a barrier. A process for preparing a gas-filled
sachet containing an extrudable composition comprising plurality of distinct
phases, comprising the steps of: a. conveying a sheet material to a sachet
7
fonner where the opposite longitudinal edges of the material are overlapped
and parallelly juxtaposed; b. sealing said overlapping edges of said sheet
material to fonn a hose where said sealed edges derme the longitudinal seam of
the sachet; c. sealing the leading edge of said hose by a frrst transverse seal to
fonn the top transverse seam of the sachet to define a dispensing passage,
where the dispensing passage is defmed by the seal on either side of the
passage but the seal runs across the transverse edge above the diSPensing
passage in order to close said passage; d. filling said extrudable composition
comprising plurality of distinct phases through a filling means, followed by a
stream ofgas, which stops the filling action and fills in the free space within the
sachet; sealing the other open end of said hose at a desired location in a second
transverse sealing, said sealing defming the bottom transverse seam of the
sachet.
The invention of the document 00794IDELNP/2003 a dual chamber sachet
with a dispensing outlet can be made in a form/fill sequence by attaching the
dispensing outletto the film that is to fonn the chamber divider wall followed
by attaching ftlms that are to fonn the outer walls of the sachet to the
dispensing outlet. The upper and side lateral edges ofthe sachet then are sealed
together to produce a sachet with an open bottom end. The sachet can be
produced from three ftlm sources, two ftlm sources with the outer walls being
8
fonned from, a single fJ.lm , or from a single fJ.lm fonned into a W-shape. The
sachet preferably is filled through the open bottom end and the bottom end then
sealed. However the sachet can be top fIlled through the nozzle. The sachets
then are severed one from, the other by cutting along a lateral seal and packed
into a carton, or prefonnatted along a lateral seal and cut to produce a string of
a set number of sachets. The sachets can have a single use dispensing outlet or
a reclosable dispensing outlet. Larger sachets will have a reclosable disPensing
outlet.

According to the document JP2003205916 a substantially improve some
disadvantages of a packaging machine for a snack food having some crumbs, in
particular, in which a product placed on a closer bar passes over the closer bar
and is drawn out, the products such as crumbs come to an area between seal
11
jaws, a poor seal is generated and a damage of bag material is generated. ;
There is provided a rotaIy packaging machine having peeling bars, rotationally
driven to peel off a tube-like bag material 36 prior to sealing against a bag to be
fonned. Further, there are provided tube closer bars to prevent the product from
coming between the seal jaws. The bar has a longitudinal extending protrusion
and this is accepted and stored in a notch extending in a longitudinal direction
of the bar. The protrusion is engaged with the notch and the tube-like bag
material 36 is bent at three positions spaced apart in a longitudinal direction.
According to the other invention stated in the docwnent JP2004099 I73, a

brake installed inside a brake roller and the other brake installed inside a
rotating shaft of a packaging material roll. The brake for the fITst packaging
material roll is released when the film is joined and an amount ofbraking of the
brake roller is increased. When it is detected that the film joining part passed
through the brake roller, the brake for the second packaging material roll is set
to its specified value and at the same titne an amount of braking at the brake
roller is decreased.

The other document US7159376 describes a rotmy packaging machine
including: a pair ofrotatably driven jaws to engage tubular bag material passing
through the machine in a general direction of travel, the jaws being adapted to
fonn transverse seals in the bag material to fonn discrete bags containing
product; a drive member supporting each jaw, the drive members being driven
in synchronism in opposite rotational directions; and an assembly to at least
substantially prevent product being located between the jaws during sealing
engagement with the tubular bag material, said assembly having a ftrst
operative configuration allowing product to pass along the bag material and a
second operative configuration, said assembly when in said second
configuration being engaged with the bag material to at least substantially
prevent product being located between the jaws during sealing, said assembly
including bag material deflecting and closing members mounted on said drive
members so as to rotate therewith, which deflecting and closing members close
said bag material and deflect the closed bag material laterally relative to said
direction to at least substantially prevent product being located between the
jaws when fonning said seals.
With respect to US6052971 there is described therein a packaging machine
provided with "wiper means" in the form of overlapping engagement portions
13
that strip the bag material and cause the bag material to move upwardly relative
to the sealing jaws.
US4566253 describes a packaging machine that includes a series of interacting
rollers that move the bag material upwardly to thereby strip the bag material by
causing the bag material to move between a pair of stripping jaws. The
interacting rollers reciprocate lineally in a direction generally transverse of the
bag material.
There is a need, if not a demand, for a Continuous Rotary Assembly Apparatus
that enables the cams to be easily and readily changed; said cams directly or
indirectly being responsible for a mechanical action or inaction. If the cams
could be changed, one machine could be used to produce a product ofdifferent
sizes or fill a container with different quantities of product. The ability to use
an apparatus for multiple purposes significantly reduces the investment a
company would have to make in purchasing a machine for every- purpose. The
reduction in investment for special purpose machines directly relates to a
company's profit structure. In other words, an apparatus that can be used as a
bottling machine and canning machine simply by changing cams reduces the
investment ofa company by one machine. This saves money; hence resulting in
larger profits.
14
Thus, the packaging machinery industry, and particularly with regard to form,
fill and seal packaging machines, fmds itself in a situation where computerized
combination weighing is at a very advanced level to provide highly accurate
weighing at greatly increased speeds, and the actual package fonning apparatus
and method has likewise reached a very advanced state. However, little or no
control is provided in the area oftransitional product flow between the weigher
and the packaging fonning apparatus. In other words, once the product charge
from the combination weigher is fonned until it reaches the package fonning
station, that is where the package is filled, fonned and sealed, little or no
advancement has been made. Essentially, the industty is still relying on the
worst case scenario that occurs in the transitional product flow path along
which the product charge must travel between the combination weigher and the
package fonning station. This results in the packaging machinery operator
having to slow the system to accept the slowest product charge and the longest
charge stringout (vertical spread), when in fact the machine/process is
optimized in the other two areas (combination weighing/package fonning). We
have recognized that this transitional area of the packaging machine has
become the proverbial bottle neck of the machine/system and we believe the
time has come for its elimination.
15
