Abstract
Description
- The present invention relates to a device particularly for conveying a product, such as tobacco, into a container.
- Currently it is known to accumulate tobacco, in its various forms (for example in leaves, strips, shag, cut filler, expanded laminas and ribs, et cetera) in appropriately provided containers, both to store it temporarily within the production facility and to be able to transport it.
- These known types of container are typically made of rigid material, generally plastics, metal, wood or cardboard, are shaped like a parallelepiped, and have dimensions that can vary according to specific requirements; the upper surface of these containers is open or can be opened to allow their filling.
- In order to introduce tobacco in these containers, known types of device, known as "filling stations", are used which generally comprise a device for inserting and spacing the container (which comprises appropriately provided rollers or chain conveyors or other known movement devices), and a magazine that can be lifted and is constituted by a hollow box-like body, which is open at its upper and lower ends and is arranged above the container to be filled, at its upper open face, and is filled from above.
- The lower rim of the magazine is rested against the upper rim of the container to be filled, or is inserted therein, and thus acts as a collector for conveying the tobacco into the container.
- These known types of filling station further comprise a pressing head, which has a vertical stroke and is generally pneumatically or electromechanically actuated and is adapted to compress the product introduced in the magazine and push it into the container.
- These known types of filling station are used generally to provide compression ratios of approximately 1/2 between the density of the tobacco introduced in the magazine and its density after compression; the height of the magazine is set as a function of the compression ratio to be obtained.
- Typically, these known types of filling station are designed as a function of a specific container to be filled, which has fixed dimensions and is adapted to obtain a predefined compression ratio; the magazine is thus preset, already during design, with plan dimensions that correspond to the plan dimensions of the container to be filled, and with a suitable height as a function of the compression ratio to be obtained.
- The pressing head therefore also has plan dimensions that correspond, albeit slightly reduced, to the plan dimensions of the magazine, so as to perform uniform pressing of the tobacco, avoiding losses thereof between the side walls of the magazine and such pressing head.
- However, these known types of filling station have a drawback: they cannot in fact be used to fill containers that have different dimensions, and therefore, in order to be able to fill such containers, it is necessary to have as many separate filling stations as there are different plan dimensions of the containers to be filled, with the consequent problems that this entails both in terms of costs, space occupation and management.
- Filling stations are also known which allow the filling of two different containers that have two definite different plan dimensions.
- These known types of filling station comprise two separate magazines, which have different plan dimensions and are mounted on rails or other sliding means that allow to extract one magazine from the working position and insert the other magazine in its place.
- Even these known types of filling station, however, have drawbacks; since they must have two distinct magazines and a device for moving them, they have high constructive complexity and production costs.
- Further, these known types of filling station have a large horizontal extension and therefore require a space that offers a large area for their placement.
- Moreover, replacement of one magazine with the other is rather complex and laborious, since it requires to disconnect and then restore the electrical and pneumatic connections between the magazines and the rest of the filling station.
- Filling stations are also known which have a magazine in which the dimensions of its lower rim, which can be inserted in the container to be filled, can be modified.
- In these known types of filling station, the magazine in fact has a frame that has a square or rectangular plan shape and to the sides of which the upper perimetric edges of four partitions are pivoted, such partitions having a substantially rectangular or square profile and an inclination that can be modified selectively by way of suitable linear actuators in order to move mutually apart or closer their lower perimetric edges.
- These partitions therefore can assume, as a whole, a spatial configuration that can pass selectively from a parallelepiped to a truncated pyramid.
- These known types of magazine are generally used to facilitate the insertion of their lower rim in the container to be filled, and also in order to be able to fill containers that have different plan dimensions.
- However, these known types of filling station also have drawbacks:
since the pressing head is sized so that it can pass through the magazine in the condition in which the discharge port of such magazine has the minimum plan extension, in the condition in which such discharge port has a larger extension there is considerable play between the pressing head and the side walls of the magazine, with a consequent substantial loss of product during pressing; for this reason, this known type of solution is used generally only to fill containers having size differences of a few centimeters. - The aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited background art, by providing a device that allows to fill containers that have different plan dimensions, maintaining low production costs.
- Within this aim, an object of the invention is to provide a device that allows to fill containers whose plan dimensions have differences of even more than a few centimeters.
- Another object of the invention is to provide a device that allows to fill containers of various dimensions without entailing the replacement of one or more of its components.
- Another object of the invention is to provide a device that can be installed even in enclosed spaces that have a limited horizontal extension.
- Another object is to provide a device that is structurally simple and has low manufacturing costs.
- This aim and these and other objects, which will become better apparent hereinafter, are achieved by a device, particularly for conveying a product into a container, which comprises a magazine, having a substantially square or rectangular plan shape, which can be arranged above said container and in which a pressing head is associated slidingly, characterized in that said magazine has first means adapted to vary selectively its volume, maintaining for said magazine a same geometric configuration, said pressing head having second means that are adapted to vary its useful thrust surface as the volume of said magazine varies.

flaps central body 27 of thepressing head 26, thesecond laminas 31 of theflaps first laminas 27a of thecentral body 27, the first andsecond laminas like elements 33 inserted in appropriately provided holes, not shown in the accompanying figures, which are formed transversely to the first andsecond laminas - Advantageously, the
flaps central body 27 between a closed position, shown inFigure 10 , in which they do not protrude in plan view from thecentral body 27, and a maximum opening condition, shown inFigures 11 and12 , in which they protrude in plan view from thecentral body 27 so as to block approximately completely, together with thecentral body 27, the discharge port of themagazine 8 in the condition of maximum plan extension thereof. - Advantageously, the rotation of the
flaps central body 27 can be performed automatically by way of appropriately provided second actuation means, which are constituted for example by appropriately provided secondlinear actuators 34, which are preferably electrical or pneumatic and have asecond body 34a, which is fixed to thecentral body 27, and asecond shank 34b, which is connected by way of suitable connecting means to one of the twoflaps - Advantageously, such connecting means are constituted by a
first lever 35, which is approximately Z-shaped and is hinged, at a first end, to the free end of one of theflaps second lever 36, which is pivoted in turn to thecentral body 27; alamina 37 is fixed approximately at right angles to thesecond lever 36 and in turn is pivoted to thesecond shank 34b of the secondlinear actuator 34. - Means are provided which are adapted to contrast, during pressing, the re-closure of the
