Abstract
Description
- The present invention relates to wrapping articles with a packaging sheet.
- More precisely, the invention relates to a method and an apparatus for wrapping articles stacked in piles or in rolls by a film of plastic material, e.g. polyethylene.
- It is known that consumption articles, such as rolls of toilet paper or kitchen towels are usually packaged in packs or groups by a film or plastic transparent material, e.g. polyethylene, polythene, polypropylene, etc.
- At present, the articles are packaged by machines, which form groups of articles, usually in a loading or collecting tray, and which push the grouped articles upwards by means of a raising plate, against a sheet of plastic material, which is kept spread over the plate.
- The group of articles is introduced into a space, which is formed by fixed walls and which those skilled in the art call "hopper".
- Thus, the sheet of plastic material wraps the upper surface of the so grouped articles.
- In phase relation with the raising plate downward return movement, the sheet is tucked in against the lower surface of the group of articles by two movable horizontal plates.
- Then, a conveyor, equipped with vertical arms, moves the group of articles wrapped with the sheet of plastic material toward a welding station, where the package is closed by welding the overlapped edges of the sheet of plastic material, on the lower surface of the grouped articles.
- The above solution is undoubtedly complicated due to the necessity to foresee different changes of the groups of articles movement, which results in high construction costs.
- Moreover, it is also obvious that each change of the direction requires a stop for group of articles.
- The time intervals necessary for different stops accumulate, due to a high number of packages being produced and consequently, the total stop time becomes significant.
- In addition to the technical and production considerations presented previously, the currently used constructive solutions feature another drawback which lies in the closure welding, which must be made on one of the biggest surfaces of packages or groups of packaged articles.
- Considering its upward movement, the just formed group of articles hits the sheet of plastic packaging material with its larger surface and the sheet is tucked on the opposite surface by overlapping and welding the edges thereof.
- This reduces the possibility to use the entire surface, limited by the welding, for printing commercial advertisements or other kinds of information.
- The object of the present invention is to propose a method for wrapping articles, according to which the groups of articles move as linearly as possible and without changes of direction or stops necessary for this purpose.
- Another object of the present invention is to propose an apparatus which carries out the above method, which is simple to construct and which is easily and rapidly adaptable to different sizes of articles to be packaged as well as of the ready packages, without the necessity to use a complicated structure, thus lowering the production costs.
- A further object of the present invention is to propose a method and an apparatus which produce packages formed by groups of articles according to what has been presented previously, and which allow to leave completely free the two most extended surfaces of the packages or groups of packaged articles, so that these surfaces can be used for printing commercial advertisement or other information.
- The above-mentioned objects are obtained in accordance with the content of the claims.
- The characteristic features of the present invention will be pointed out in the following description of a preferred, but not only embodiment, with reference to the enclosed drawings, in which:
- Figure 1A is a partial, schematic top view of an apparatus for wrapping articles with a packaging sheet, taken in the region of the inlet area for the articles to be packaged;
- Figure 1B is another partial top view of the apparatus, taken at the outlet area for the articles being packaged;
- Figures 2 and 3 are section views of the apparatus, taken along the planes II-II and III-III in Figure 1A;
- Figure 4A is a lateral schematic view of the proposed apparatus, from the side indicated with K in Figure 1B;
- Figure 4B is a lateral schematic view of the proposed apparatus, from the side indicated with K in Figure 1B, according to a variant;
- Figure 5 is a perspective view of a few steps of the wrapping of a group of articles in rolls according to the proposed method;
- Figure 5A is a group of articles formed by more layers of articles, e.g. two.
- With reference to the above figures, the
reference numeral 1 indicates a feeding line forarticles 2 to be wrapped with apackaging sheet 3. - The
feeding line 1 is formed by e.g. a conveyor equipped with a series ofbars 4 defining spaces, which receive thearticles 2 to be packaged, already arranged in groups according known techniques. - Each space defined between the
bars 4 is provided withrelated pusher members 5, which are aimed at transferring groups ofarticles 2 crosswise to theline 1. - The
pusher members 5 are carried, according to known techniques, by conveying means, not shown, arranged beside thefeeding line 1. - A
panel 6, situated beside the initial part of thefeeding line 1, acts as a stop supporting the groups ofarticles 2 inside the spaces defined by the bars 4 (Figure 2). - The
panel 6 extends up to the point, in which thefeeding line 1 is located beside aline 7 for wrapping the groups ofarticles 2. - The
line 7 for wrapping groups ofarticles 2 extends beside thearticles 2feeding line 1 and wraps the groups ofarticles 2 with respective packaging sheets, which are preferably constituted by a film of plastic material, e.g. polyethylene, polythene, polypropylene, or another material typically used for packaging. - The
wrapping line 7 is formed by a pair ofconveying belts - The
conveying belts rolls 70 and are operated in opposite directions, with peripheric speed equal to that of thefeeding line 1, so as to define respective opposite runs, which move simultaneously in the forward movement direction A (see Figure 4). - The
sheets 3, perfectly cut from a bobbin of the above mentioned packaging material, are arranged kept spread out, by suitable support and movement means 8, on a vertical plane, in an intermediate position between thearticles 2feeding line 1 and thewrapping line 7. - More precisely, the
sheets 3 are moved in the forward movement direction A, with a speed equal to the speed of the above mentionedlines belts 9, situated respectively above and below horizontal planes defined by theconveying belts - The
belts 9 are carried and operated by known turn-aroundmeans 8, shown in a schematic way. - According to the method for wrapping
articles 2, proposed by the present invention and shown schematically in Figure 5, the groups ofarticles 2 to be packaged are conveyed along thefeeding line 1. - According to known techniques, the groups are formed previously between two lateral guides, not shown, and then pushed orderly inside the spaces defined by the
bars 4, having their lateral shorter extension turned in the forward movement direction A. - If the
articles 2 are e.g. rolls of paper, the groups to be packaged are advantageously formed by a series of rolls arranged side by side longitudinally in only one layer or in two layers, put one over the other, and the above mentioned lateral shorter extension coincides with the lateral extension of the rolls arranged side by side. - From this point forward, there are no more stops or sudden changes of the forward movement direction, which would require such stops.
- The single packaging sheets, arranged on a vertical plane, are moved forward in suitable time relation with the forward movement of the
articles 2 along thefeeding line 1. - Then, the groups of
articles 2 are transferred by thepusher members 5 crosswise to thefeeding line 1, as it is clearly shown in Figure 1A, so that the articles are introduced between the opposite runs of theconveying belts wrapping line 7, which is operated with the same speed as thefeeding ling 1. - During this transferring, the lateral narrowed dimension of the groups of
articles 2 hit thepackaging sheets 3, so as to fold the latter following the U-shape. - In this way, the
sheets 3 wrap the most extended surfaces, i.e. upper and lower, of the groups ofarticles 2. - During the step of introduction of the groups of
articles 2 between theconveying belts sheets 3 while being folded. - The groups of
articles 2, partially wrapped with thesheets 3, introduced between theconveying belts wrapping line 7. - During the forward movement along the
line 7, the open ends of the folded parts of thesheets 3 meet the stationary folding means 11, suitably shaped, which are aimed at folding the open ends and overlap them, so as to complete the longitudinal wrapping of the groups of articles 2 (Figure 4A). - If the packages include two layers of articles arranged one on the other, as shown in Figure 5A, the distance between the
belts packages 22, as shown in Figure 4B. - The folding members, indicated in this case with 41, have such a shape as to overlap the edges in the region of the center line of the lower layer of articles, or rolls, for the purpose which will become evident later on.
- Coming back to the configuration of a single layer of packages (Figure 4A), the overlapped edges of the folded parts of the
packaging sheets 3 are joined by abelt welding member 12 of known type, which acts along thesame wrapping line 7, downstream of the folding means 11, in the forward movement direction A. - Therefore, the
sheets 3 are welded along the longitudinal side of the groups ofarticles 2, opposite to the one which hits thesheets 3, having a corresponding narrowed dimension; thewelding line 33, indicated in Figure 4A, is situated more or less in the central area of the narrowed dimension of the package, or shifted a bit with respect thereto. - In case of the two-layer configuration (Figure 4B), the welding member is situated in such a way that the
welding line 33 is situated in the central area of e.g. the lower layer of articles, or shifted a bit with respect thereto. - In this way, the welding member presses the overlapped edges always against the article or articles situated below, and not against an empty area, which is created in the central part of the package side.
- At the outlet of the
wrapping line 7, the groups ofarticles 2, wrapped with thepackaging sheets 3, closed all around, are subjected to the change of the direction of forward movement of theline 7, without the stops, so as to close the packages in the regions of the opposite heads of thearticles 2. - Other folding and welding means, not shown, acting along a
line 13 of the packagedarticles 2 outlet, close the packages. - The packages are transferred to the
line 13 by e.g. atransporting device 14, rotating on a vertical axis, seen in Figure 1B. - The rotating
transporting device 14 features a series ofradial arms 15, which carry on their free end, pivoted by apin 16, respective picking up means 17 extending downwards. - The picking up means 17 pick up the groups of
articles 2, wrapped with thepackaging sheets 3 wrapped all around them, and transfer them orderly to theoutlet line 13, maintaining unchanged their orientation due to the simultaneous rotation on thepin 16, in the direction opposite to the rotation of theconveyor 14. - The action of the picking up means 17 is possible due to the fact that the
lower conveying belt 72 extends longitudinally beyond the extremity of theupper conveying belt 71, as clearly seen in Figure 4a. - Two or
more bands conveying belt 72 extending beyond theupper conveying belt 71. - The
bands conveying belts - The
bands lower conveying belt 72, situated below. - In this way, access to the groups of articles of the upper part is made possible.
- The groups of
articles 2 below thebands movable parts 17a, 17b of the picking up means 17, which move close from above and grip the group ofarticles 2 therebetween. - The rotation of the transporting
device 14, performed in phase relation with the movement of the conveyingbelts belt 72 and theupper bands - After having rotated by 90°, the picking up means 17 release the previously picked up group of articles onto the
outlet line 13 and, simultaneously, the package is rotated in the direction opposite to the rotation of the rotating conveyor, so that the package maintains its orientation, although its forward movement direction changes without stopping the movement. - The picking up means 17 release the semi-packaged group of articles in the initial area of upper holding
bands upper bands - The flaps of the still open heads of the package are folded and welded together along the outlet line.
- Consequently, the method and apparatus according to the present invention achieve the aim of wrapping articles, such as in particular rolls of paper or the like, gathered in packs or groups, within a film, in such a way as to leave perfectly free from welding both the most extended surfaces of the packs or groups of packaged articles.
- This allows not only a better presentation of the package, but also the use of both most extended surfaces to support commercial, advertisement or other kinds of information.
- All this is obtained while the products follow a path without sudden trajectory changes nor stops required thereby.
- It is to be pointed out that an apparatus of simple structure, functional and extremely versatile, obtains this result.
- Actually, in order to adapt the machine to different sizes of the
articles 2 and/or packages, it is enough to change the distance between the twobelts bars 4. - There are no stops or direction changes along the whole path followed by the packages, beginning from forming of the groups of articles.
- This allows to simplify in maximum way the structure of the machine and to facilitate its operation considerably.
- In addition to the positive effect on the production and maintenance costs, it is also possible to increase the production rate by eliminating all stops, which are no longer necessary.
