Field of the Invention
This invention relates to a 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.
Background of the invention and the related Prior Art
Conventionally blister packages have been constructed in a discontinuous manner. Typically, a sheet of thin, usually transparent and thermoplastic material is pressed, for example, by vacuum forming to form the blister or blisters, i.e., depressions, in the sheet which are sized to retain the article or articles. The blisters are then filled with the articles, usually one per blister, and then a second sheet usually of opaque material is adhesively bonded to the first, typically by heat sealing or in the application of adhesive material, thus sealing the articles between the two sheets. The laminated sheets may then be die cut to separate the discrete unit-packages. In this type of construction the blisters are usually sized to fit the article closely.
A similar type package is formed in a cominuous manner by passing a pair of webs of indefinite length of usually transparent, thin material between a pair of laminating rolls. The laminating rolls contain die cavities which come into register as they pass through the nip of the laminating rolls, and an article feed is directed to the nip of the rolls to feed articles by gravity one at a time in synchronism with the closing of the die cavities, such that, as the die cavities pass through the nip, the two webs of material have the article positioned between them. In this type of machine the two webs of material are caused to adhere, for example by application of heat where a thermoplastic material is used, at the location of the nip of the rolls by heating one or both of the rolls. In such an arrangement the article feed device is a chute which is adapted to allow the articles to fall by gravity one at a time by means of a pin which obstructs the chute retaining a supply of articles stacked above, one on the other. The pin is timed to be removed and rapidly inserted in the chute, such that a single article falls into the pocket between the two webs formed by the closing die cavities at the nip of the laminating rolls. In this arrangement the die cavities are substantially larger than the article to be received between them.
Wraps and preformed bags are considered to be the traditional packaging methods in the present packaging industry. 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.
Preformed bags are also an old and well known form of packaging which were originally made by hand to provide convenience in handling, filling, and closing. The materials used for preformed 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 form/fill/seal pouch type of flexible packaging is considered to be an extension of the preformed bag art. The significant difference over the preformed bag is that the form/fill/seal pouch structure may be continuously formed 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 general categories: wraps, preformed bags, and form/fill/seal pouches. In all of the above categories, the packages are formed 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 US4537012 describes a sealing jaw mechanism for a packaging machine, the jaw mechanism having a pair of elongated parallel drawbars extending transversely of a given axis, a pair of opposing sealing jaws, each of said jaws being carried by an associated one of said drawbars, and rotary actuating means for moving said drawbars in one and an opposite direction relative to each other along said given axis to move said jaws between open and closed positions and including a pair of transversely spaced apart rotary actuating members supported for rotary movement about another axis extending transversely of said given axis, means for connecting said drawbars to said rotary actuating members to move in response to angular movement of said rotary actuating members, and drive means for imparting angular movement to said rotary actuating members, the improvement comprising said drive means including a pair of rotary actuators, each of said actuators having a drive shaft projecting from its opposite ends, means for coupling the inboard ends of the drive shafts to each other in coaxial alignment to rotate in unison, the axis of coupled driveshafts extending transversely of said given axis, each of said actuating members being connected to an outboard end portion of an associated one of said drive shafts.
According to the document US5351828 the invention relates to a foil sachet with at least one chamber consisting of an upper and lower foil secured together by a closed seam. In order to fill the chambers with a substance, especially air, there is a channel having
channel sections opening in the region of a seam and preferably in the region of the corner of the chamber concerned where there is an aperture in said chamber. There are preferably a main and a subsidiary charmel wherein the main channel may also run outside the foil sachet.
The present dual chamber sachet overcomes the problem of non-uniform dispensing when the sidewalk of the sachet are depressed. Through the use of a relatively thin intermediate divider wall, rounded corner edges at the lower end of each chamber of the sachet, tapered side edges up to the exit channel of each chamber of the sachet, and a relatively wide dispensing opening uniform 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 IN/PCT/2002/01071/DEL.
The document 513/MUM/2006 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 former where the opposite longitudinal edges of the material are overlapped and parallelly juxtaposed; b. sealing said overlapping edges
of said sheet material to form a hose where said sealed edges define the longitudinal seam of the sachet; c. sealing the leading edge of said hose by a first transverse seal to form the top transverse seam of the sachet to define a dispensing passage, where the dispensing passage is defined 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 of gas, 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 defining the bottom transverse seam of the sachet.
The invention of the document 00794/DELNP/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 form the chamber divider wall followed by attaching films that are to form the outer walls of the sachet to the dispensing outlet (24). The upper and side lateral edges of the sachet then are sealed together to produce a sachet with an open bottom end. The sachet can be produced from three film sources (10, 14, 1 8), two film sources (92, 94) with the outer walls being formed from, a single film (80), or from a single film formed 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 (24). The sachets then are severed one from, the other by cutting along a lateral seal and packed into a carton, or preformatted 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.

Turret and cam operated apparatuses are well known in the art, primarily in the food processing industry. The existing turret and cam operated apparatuseses are special purpose machines; for example, a bottling machine that delivers a specific quantity of fluid into a bottle. The design of the existing turret and cam operated apparatuses inhibits the changing of cams, thus inhibiting the change of use of the apparatus. That is why the existing apparatuses are special purpose machines. Further, continuous rotary machines are difficult to tool and maintain because of their common center shaft suspension. It is the cams that enable a mechanical function or process to occur. Therefore, if the cams could be readily changed, that which was a special purpose apparatus would now be a multi-purpose apparatus. Further, the ability to change cams would enable one machine to process various sizes or quantities of the same product.
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 of different 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 of a company by one machine. This saves money; hence resulting in larger profits.
