Definitions
- the present invention relates to a method for packing or packaging together a number rolls of papers or paper-like material wound onto a core, which rolls are squashed or laterally compressed in order to reduce their overall bulk.
- such packaging is accomplished by wrapping with a plastic or paper film the rolls that have been compressed and deformed to reduce their dead space resulting from both the hollow cylindrical cores on which the rolls are wound, and from the voids created when the cylindrically shaped rolls are disposed side by side.
- the present invention is concerned with packages wherein the rolls are toilet paper rolls or similar articles, and are arranged in two or more layers.
- the known packages of a plurality of toilet paper rolls or the like, having a cylindrical (i.e. not deformed) shape, are formed by placing a given number of rolls side by side, in lateral contact and with their axes parallel, to form a so called layer.
- a layer can comprise a single row of rolls or two or more rows of rolls located one behind the next.
- a single layer for example made up by two rows each comprising 5 rolls, can be encased into a plastic material sheet to form a package containing 10 rolls in total.
- Another kind of known package consists of two or more layers of rolls placed one on the top of the other, forming the so called “bundle" which is then wrapped.
- WO 93/04966 discloses an article formed by a paper web wound around a core to form a roll that is then compressed and flattened, and retained in the deformed state by a band or other individual constraint.
- EP-A-0 392 581 discloses in particular a packaged product, formed by a plurality of such flattened articles, disposed side by side to form a layer and encased in a sheet or film of plastic material.
- Italian Patent N. 1 177 749 discloses a method for deforming individual paper rolls wound on a core, and wrapping them in a heat-shrinkable material sheet which is heated for shrinking around the article.
- US-A-5 195 300 discloses a method and an apparatus for packaging a plurality of paper rolls that are in a compressed state, and provides for a progressive and continuous compression of the individual rolls, their subsequent 90° rotation about a vertical axis, and then the bunching of the rolls with an additional compression and their introduction into a plastic material tube which is then sealed at its ends.
- US-A-4 679 379 relates to an apparatus for packaging a bundle of paper rolls by compressing the whole bundle and wrapping it into a heat-shrinkable material sheet.
- the deformed rolls are arranged to form a layer, as defined above, formed by one or more rows with each row comprising two or more deformed rolls.
- the known methods and apparatuses for packaging rolls that are in a flattened or compressed state are not capable to produce packs or packages formed by two or more layers, i.e. with rolls stacked one over the other along the "short" dimension resulting from the roll compression.
- the object of the present invention is to overcome the above described drawbacks and limits of the prior art.
- a plurality of paper rolls 1, 2, 3, 4, 5, wound on cores 6, are advanced laying on their side i.e. with their longitudinal axis disposed horizontal, on (first) conveying means 30 after being supplied from a roll store (not shown).
- the conveying means comprises a movable belt or carrier 30, provided of suitable lane dividers or separating members, being of course possible to employ a plurality of individual belts or carriers disposed side by side.
- the rolls are then transferred to a device 32 carrying out a continuous compression of each individual roll.
- Such compression will be referred to as the first compression.
- One component of the compressing device 32 is shown with a somewhat greater detail in Fig. 1. The description which follows will generally refer to a single roll, being evident that such disclosure applies to all the other rolls 1 to 5 (or more), since the treatment of each roll is the same.
- the rolls are then accumulated along one or two or more rows to form a layer, and two layers 10 and 11 formed in the afore described way are stacked in a wrapping machine to form the bundle in its final configuration. Then the bundle undergoes a further or second compression, immediately before being wrapped with a plastic or paper material film 13.
- a layer is formed of three axially aligned rows, each row being formed by five rolls.
- the continuous compressing device 32 comprises, for each parallel conveyor of an individual roll, a pair of endless conveyor belts 21, 22, horizontally disposed and movable between two pairs of rolls, that is two front rolls 25 and two rear rolls 26, respectively. Additionally, in a first section, the passage width or distance between belts 21 and 22 becomes progressively narrower, with the belts forming a sort of funnel where the roll 1 is progressively compressed while being advanced, so as to impart a substantially elliptical shape to the roll.
- the continuously compressing device 32 further provides a second section having a constant width, where the compressed roll is advanced with its longitudinal axis horizontal and the longer axis of the elliptical section vertically disposed.
- the device 32 is not provided with a bottom member (such as a belt or other sustaining surface) where the rolls can rest since belts 21 e 22 ensure the correct advancing thereof.
- At least one roll for each belt is motor-driven, and the belts are fitted with a transverse adjusting feasibility.
- Shims 27 and 28 are disposed inside the belt paths and preferably each compressing path comprises, as above mentioned, a first section having a progressively decreasing width, followed by a second section of constant width and equal to the minimum spacing of the first section.
- the compressed rolls 1D-5D are moved to a second conveying means, generally indicated with 34, to be subsequently directed to a pneumatic compressing device indicated with 36.
- the second conveying means comprises a single carrier or belt provided with divider members, or alternatively a plurality of adjacent belts.
- the compression takes place while the rolls are stationary, and the device operates at the same time on a plurality rolls disposed side by side, and a second compression is imparted them such as to remove the remaining dead space within the hollow cores 6. After this second compression, the rolls assume their final flat configuration.
- a blade or bar 38 is provided between the first compressing device 32 and the second compressing device 36, and is cyclically operated upwardly and downwardly by conventional means not shown in the drawings.
- the bar 38 causes the sequential advancing of a predetermined number of rolls over each conveyor. In the embodiment shown in Fig. 2, two rows of rolls are moved into the second compressing device 36 one after the other.
- the compressing device 36 has a substantially parallelepipedal shape and comprises a board or a baseplate 46, that is vertically moveable by a pneumatic cylinder 50 or similar device, two fixes vertical walls 40 and 42, adjacent and normal to one another, and a vertical wall 44, horizontally movable along both directions, and actuated by a pneumatic cylinder 48 or similar device.
- One side of the device 36 is open for receiving the incoming rolls, and the top of the device is open for extracting the formed bundle.
- a layer of rolls comprising two rows of five rolls, is pushed into the device 36 by the conveyors 34. After their deposition on the baseplate, the rolls are further compressed by the side wall 44 moving toward the wall 40 under the action of the cylinder 48. At the end of such compressing step, the cylinder 50 lifts the roll assembly or bundle toward a wrapping device (not shown) that will encase the rolls into a plastic or paper material film 13 (Fig. 1).
- Figs 4A to 4H there is further illustrated the method according the present invention for obtaining a package of compressed rolls arranged on two layers.
- the second compressing device (indicated with 36A in Fig. 4A) provides for two parallel and pneumatic cylinders disposed one above the other, respectively 48 and 52, and a movable wall 44A made up by two parallel and adjacent plates 47, 51, each being fixed to the piston rod of the related cylinder.
- a portion of the working plan 54 of the apparatus frame is used as a supporting surface for the outermost roll adjacent to the movable wall.
- the plates 47 and 51 are sligthly spaced from the edge of the plate 46, and the roll partially rests upon the plane 54.
- the compressing cyclic operating sequence is as follows.
- cylinder 50 is lowered at a position such that the bottomplate 46 is flush with the level of the frame working surface 54 (Fig. 4A).
- the cylinder 50 is then actuated to lift the board 46 and raise the first layer of compressed rolls to the plate 51 level (Fig. 4D).
- the board 46 is then lifted by cylinder 50 to a second level, such as to raise both compressed layers above plates 47 and 51.
- the two layers are kept in a compressed state by a pair of properly spaced fixed plates 52 and 53, during the wrapping with the material 13.
- Figs 5A and 5B there is illustrated another method for stacking two layers of rolls one above the other.
- the conveyor belt device 34 has been modified so as to include three consecutive and adjacent sections.
- the first section 34A is horizontal and similar to the one provided in Fig. 2 at the end of the first compressing device 32.
- a second portion 34B is provided adjacent to section 3A and is formed by a pivotable conveyor, hinged at the end 35 proximate to the first section, that can be upwardly inclined with respect to the plane of the fixed section.
- the section 34B includes a pair of chains 37 driven by two rotating crown gears 39, (only one being shown in the Figures).
- a transverse bar 38A is fixed with both ends to the chains 37 and pushes two rows of rolls 41, 43 onto a third horizontal section of the conveyor indicated at 34C.
- the pivotable conveyor forming the section 34B is in a horizontal position when the first layer of rolls 41, 43 is pushed and deposited onto the conveyor 34C by the bar 38A.
- the so formed bundle is introduced into a compressing device such as that already shown by Fig. 3, that carries out the second compression of all the layers at the same time, after which the bundle is wrapped by a plastic packaging material.
