In a preferred embodiment, as illustrated in FIGS. 3a and 2b, an exemplary conveying apparatus 200 having an incoming feed line 202 carrying a continuous supply of beverage containers 290 and employing a buffer unit 220 for selectively buffering the beverage containers 290 while conveying the same towards an outgoing feed line 204 is provided. The apparatus 200 further includes a grouping unit 260 for grouping the one or more beverage containers 290, in a desired predetermined arrangement at an out-feed line 204. The in-feed conveying line 202 is generally a conveying apparatus adapted to facilitate a movement of a supply of beverage containers 290 from a source such as infeed station [not shown] towards a destination such as an outfeed station [not shown] adapted to perform packaging of the beverage containers 290 of the current disclosure.

[0070] In a preferred embodiment, the beverage container 290 is a generally cup shaped container having a generally cylindrical shape. While the shape of the beverage container 290 is cup shaped for exemplary purpose only, it should be understood that the beverage container 290 may be any kind of suitable containers (e.g., cans, bottles, etc) of any shape and size, including the radius and height suitable for enclosing its contents.

[0071] As disclosed earlier, the buffering unit 220 includes a base conveyor 230 extending between a receiving end E.sub.R towards an output end E.sub.R, and adapted to receive an infeed supply of the plurality of beverage containers 290 from the in-feed conveying line 202 at the receiving end E.sub.R.

The star-wheel 245 is generally adapted to avoid any possibility of falling down and/or get damaged at the receiving end E.sub.R due to centrifugal impact of these containers 290, since this apparatus generally receives infeed supply 290 at particularly higher speed. In some embodiments, the start wheel 245 may be replaced with any suitable mechanism conventionally known in the art without deviating from the scope of current disclosure.

[0076] The distributing unit 240 further includes an alignment unit 246 configured onto a distal side D.sub.s of the first closed loop track 242, positioned generally eccentrically to the base conveyor 235 and generally parallel to the longitudinal axis L.sub.F of the first alignment unit 246 is generally positioned is at the angle substantially same as that of angle A, to the base conveyor 230.

INDUSTRIAL APPLICABILITY

[0099] The present disclosure relates to a conveying apparatus 200 having a buffering unit 220 adapted to temporarily accumulate any type the articles 290, i.e. cylindrical and non-cylindrical, and made of any type of material including glass, metal, paper, foils, thin plastic, and any combination.

[0100] The buffering unit of the current disclosure may be easily integrated into an existing conveyor line without any axial offset. Further, since there is a plurality of parallel buffer lanes, the buffering unit may be accommodated within a small base area and at a height which is mostly suitable to be handled by the users. Particularly advantageously, the utilization of such a buffering unit avoids the need of backing up the products at the infeed and/or at the outfeed.

[0101] Further, since the current buffering unit consists of plurality of buffer lanes configured onto a same conveyor means, the apparatus is simple to use and avoids adding to the complexity and costs for managing a plurality of individual buffer conveyors. Accordingly, the current conveying apparatus having buffering unit provide an improved system so to achieve lower cost per article and higher space efficiency, and therefore enabling a cost-effective inclusion of even slower moving articles.

[0102] Particularly advantageously, the buffering means of the current disclosure is configured to progressively and uniformly distribute articles into the individual tracks or lanes. Further, the dropping of the articles within the respective buffer lane may be controlled individually, and possibly, for example, as a function of sensor signals which are supplied by one or more sensors that monitor the distribution of the articles over the individual tracks buffer lanes of the base conveyor. Therefore, the current apparatus is well suited to fully automate the conveying process.

[0103] Further, the conveying apparatus is adaptable to different shapes and sizes of articles, and is therefore well suitable to process the conveying of different sizes with ease and efficiently. Moreover, the predetermined shape may be changed by simply changing the lugs 244, 274 and therefore not requiring to change the entire apparatus for different predetermined shapes.

[0104] The present buffering conveying apparatus provides the possibility of grouping articles immediately after buffering by providing outfeed via different lanes enabling formation of groups over the lanes. It is obvious that accordingly buffering and grouping can be achieved with limited machine footprint compared to conventional apparatuses.

[0105] Alternatively, the present disclosure provides the possibility of manufacturing the conveyor system with integrally formed grouping unit. Such a conveyor system for conveying and packaging articles into predetermined arrangement, while being cost-efficient, is very quick and easy to use and offers comfortable handling of articles of any shape, size or any variety of configurations.

[0106] Further, since the articles are released in the buffering lanes by the distributing lugs, and picked again by accumulating lugs for outfeed, they are conveyed contactless. This also enables conveying articles that do not resist the pushing pressure in conventional buffering conveyors, or that do not have the conventional cylindrical shape of round cans, round bottles, etc.

[0107] As the distributing and accumulating lugs are moved by movers on the closed loop tracks, they enable respectively releasing or picking an article at any lane. Therefore, the buffering conveying apparatus of the present invention offers much more flexibility while buffering than conventional buffering apparatuses. Firstly, the apparatus enables buffering in FIFO (first-in-first-out) mode as well as non-FIFO mode. Additionally, the apparatus enables separating articles, then buffering followed by grouping, as well as separating articles, then grouping and buffering grouped articles.

[0108] Additionally, since the buffering unit 220 of the current disclosure while being applicable onto the conveyor apparatus 200, does not impact the rest of the conveying process. A single conveyor apparatus 200 may utilize as many as buffering units 220 within the same arrangement.

[0109] While the conveying apparatus 200 is described primarily for conveying, buffering and grouping beverage containers, it is also contemplated for a person skilled in the art that the buffering means 220 of the current disclosure may be implemented in various industries such as food industry, transport industry, house hold appliance industry in transportation of any kind of product or group of products, of any shape, size or any variety of configurations, without limiting it to the beverage industry.
