Description
10\~41~
The present invention relates to an automatic machine for packing products of parallelepiped shape, particularly reams of paper. It has been found that for packing products of parallelepiped shape, such as reams of paper, the cardboard boxes of the type customarily used have certain shortcomings related to the fact that the product support area is not perfectly flat due to the presence of cardboard overlap areas and that this results in damage being caused to the reams.
In order to overcome this problem it has been proposed to effect the packing using boxes and lids formed out of ,,:
flattened material in which folding and cutting lines define a substantially rectang~lar central area which has along its sides sections that can be folded at a right angle theretG, the front and rear sections extending laterally with corresponding pairs of flaps that can be arranged at a right angle to the said sections and to the said central area and can go over and be glued to the lateral sections.
The automatic machines currently to be found on the market which produce a packing out of the aforementioned boxes and lids do not give satisfactory results both because of their somewhat slow running speed and because of the packing created not being perfect.
The present invention therefore provides an automatic machine for packing products of parallelepiped shape, particularly reams of paper, which has an especially high output speed and is able to turn out packs that are practically perfect.

Fig. 3 is a lateral view of the said machine; and Fig. 4 is a plan view of the machine.
With particular reference to the drawings, at 1 there S
is the complete automatic machine designed to pack the parallel-epiped shape product 2 in boxes and lids fashioned out of flattened material 3-4. The material 3-4 is customarily made of corrugated cardboard and is provided with cutting and folding lines which define the central areas 3a-4a, the front, rear and --~
'' lateral sections, 3b-4b, 3c-4c, 3d-3e and 4d-4e, respectively, as well as the flaps 3f-3g, 3h-3i, 4f-4g and 4h-4i. ~-`
~ The machine 1 comprises the magazines 5 and 6 for `~. the boxes and lids in flattened configuration, the line 7 for ., .;
i infeeding the products 2, the pusher 8, the pressers 9 and 10, the infeed line 11 and the set of rollers 12 carried by the frame 13 consisting of a structure of upright members 14, cross members 15a and longitudinal members 15b, welded one to the other.
The magazines 5 and 6 belonging to the boxes and the lids are carried, overhanging fashion, from the support frame 13 by the corresponding frames 16 and 17. Apart from ~heir dimensions, the magazines and the means for moving the individ-ual boxes and lids from the magazines to the utilization zones are virtually identical one with the other, and they are described and numbered cumulatively hereinafter.
The boxes 3 and the lids 4 are arranged one on the other and~ on one side they rest on the rollers 18, and on the other, on the rollers 19, these being carried by the frames 16 and 17, respectively. The rollers 19 revolve first in the direction of the arrow A and then in that of the arrow B, the -lnq34~s purpose of this being to first cause the extremities i-d-f of the cardboard material to be made by the roller 18 to drop on to a cardboard support platform 20 (line in dots and dashes marked I) and then to cause the extremities g-e-h to drop on to the same platform, Underneath the cardboard support platforms are arranged the pairs of gearwheels 21 and 22 around which are wound the chains 23. Between the platform and the upper part of the chain along the frames 16 and 17 are fixed the horizontal ; tracks 24 for guiding the rollers 25 of the carriages 26. To the carriages 26 are articulated the link rods 27 which, in turnr are articulated to the chains 23. As the latter are wound, the -i eyes of the link rods 27 are moved alternately along the upper3 and along the lower portions of the chains and this displaces the ~S carriages 26 alternately in the direction of the arrows C and D.
t Fixed above the carriages 26 there are teeth 28 which pass through corresponding longitudinal flutes in the support platforms 20 and are designed to move the boxes and the lids deposited thereon in the direction of the arrow C and to arrange them in the areas of the machine marked II, with the boxes resting on the support brackets 29. The product infeed line 7 is of the type that consists of an endless conveyor belt 30 mounted over driven ; and idling rollers carried by the frame 31. The latter is pro-vided with lateral guide walls 32 and is supported by an adjust-able height leg 33. A drive group 34 of known type is positioned beneath the frame 31. At the exit from line 7 which infeeds the products 2 in the direction of the arrow E, a pneumatic jack 35 is secured to the frame 13 and this is parallel with the longitu-dinal axis (a) of the machine and has a horizontal piston carrying the pusher 36 which is guided along the two horizontal shanks 37.
As the hack 35 operates in the direction of the arrow F, the said pusher contacts the products in order to carry them into the area 3a of the boxes arranged in position II. A locator 38 is fixed - 4 ~
iO~3418 j to the frame 13 to ensure the correct positioning of the produc~
in the box. In the specific case illustrated in the drawing, ~t is envisaged that products arranged in superimposed pairs are J to be arranged in the box and thus the width of the pusher 36 is slightly less than that of the two closely united products.
At the exit from line 7, the frame 13 has fixed to it the longit-udinal member 39 for locating and guiding the pairs of products coming from line 7 (position 21).
Above area 3a of the box in position II, the machine frame has fixed to it a cross member 40 which is integral with the vertic-~l shaft mounted pneumatic jack 41 whose height, with respect to the cross member 40, is adjustable through a screw ~ -~
:
j connected handwheel 42. Underneath the piston of the jack 41 is ~, fixed the horizontal bracket 43 of the presser 9. The piston is operated alternately in the direction of the arrows G and H, its travel corresponding to the height of the products and its operation in direction G subsequently to the arrival of each pair of products in position 211 causes the products and the boxes to be lowered. Below the bracket 43 is the support bracket 44 which, guided along the vertical shanks 45 and actuated by the jack 46, -~
lowers step-by-step with each operation of the brackets 43. On the sides of the frames are the pairs of members 47 which fold upwards the sections 3b and 3c as the boxes are lowered.
Once a predetermined number of pairs of products have been arranged in the box, the boxes and products are in position III shown with dots and dashes in the drawing, with sections 3b and 3c of the box substantially at right angles to area 3a.
Practically corresponding to the rear edges of the box, the machine frame has articulated to it pivotally the vertical spindles 48 and 49 with which the corresponding spatulas 50 are integral. With the rotation in the direction of the arrows I of the spatulas - the said rotation being achieved advantageously lOq3418 with means of the pneumatic jack type which are not shown on the : drawings - the flaps 3h and 3i are folded forwards in such a way as to render them practically at right angles to areas 3a and 3c.
Under the support platform 51 of the boxes in configuration III
` which extends up to the set of rollers 12, there is a longitudinal ` member 52 which is articulated to the upper extremities of the L
` shaped arms 53 and 54. These L-shaped arms 53, 54 are centrally pivoted to the upright members 55 of the machine and the lower extremity of the arm 53 and an intermediate portion of the lower part of the arm 54 fastened to the spindle 56 which together with the longitudinal member 52 and the arms 53 and 54 forms an articulated parallelogram. The lower extremity of the arm 54 is guided by the cam 57 which is so shaped that its rotation causes the raising and the lowering (arrows L) of the longitudinal mem-ber 52.
Up above the latter is fixed the horizontal track 58 for guiding the carriage 59 which through the connecting rod 60 is linked to the endless chain 61 that turns around the gear-wheels 62 and 63. As the chain unwinds, the rod 60, carried alternately along the upper and the lower portions thereof, causes the carriage 5g to undergo a to-and-fro motion (arrows M-N). The carriage 59 has articulated to it the front extremities of the L shaped arms 64 which carry the idle rollers 65 that rest on the longitudinal members 52. The gearwheel 63 and the cam 67 have one and the same drive and between one and the other the transmission ratio is such that when the carriage moves in the direction of the arrow M, the longltudinal member 58 is dis-placed upwards, whilst when the carriage moves in the direction of the arrow N,` it is displaced downwards. In the latter con figuration, along with the lowering of the longitudinal member 58, the roller 65 is also lowered and the arms 64 are carried into a configuration whereby their upper extremities remain below the lOq3418 platform 51.
During the movement in the direction of the arrow M, . , .'' ' ' 10 - 6a -10'73418 the arms 64 act on the box and its products and cause it to move from position III. On the sides of the frame are positioned converging curved locators 66 which determine the folding back of the flaps 3f-3g to carry them into a condition whereby they are at right angles with the area 3a and the section 3b.
~orresponding to where the locators 66 are to be found `~ on the frame 13, glue distribution devices 67 are mounted and these are designed to spread predetermined quantities of glue on the sections 3d-3e. In order to achieve a faster glue open time, hot melt should ideally be used. Following on after the locators 66 there are tubular locators 68 which, commencing from the ! height of the platform 51, project upwards and converge towards the central area of the platform 51. As the boxes move forward, the locators 68 cause the folding upward of the sections 3d-3e until they are carried at right angles to the area 3a resting ~ against the flaps 3i-3f and 3h-3g, respectively.
j Downstream of the locators 68 there is the set of vertically mounted rollers 12 carried by the frames 69. The latter have integral with them pairs of transverse shanks 70 guided in the horizontal axis bushes 70a fixed to the frame 13, ~` the distance the frames 69 are away from the axis (a) of the machine being adjustable through the handwheels 71 integral with corresponding adjusting screws.
Endless belts a_e mounted around the rollers 12, the latter being held pressing in the direction of the arrows (O) by elastic means of known type in such a way as to press the sections 3d-3e against the flaps 3i-3f-3h-3g and to allow the glue to grip.
The drive group 73 is anchored to the frame 13 and through suitable reduction means, it actuates the gearwheel 63, the cam 57 and the rollers 12.
The boxes now formed around the products continue to move forward in the direction of thç arrow M resting on a set of `, iOq3418 belts mounted around and supported by the transVerse rollers 74 ''~, which are powered in a known ~ashion by the drive group 74a `~ until they trip against the transverse stop 75. The latter is fixed to the piston of the pneumatic jack 75a, the operation of ,~ which is designed to move the stop 75 downwards underneath the :~
plane on which the boxes travel along in order to allow the '~ forward movement subsequent to the arrangement of the lid.
Each individual lid carried into position II by the means described previously in respect of the boxes, is supported ~ 10 in that position by the lateral brackets 76 connected to the curved, j rungs 77 which point downwards and are fixed underneath the plate ~j 78. The latter is fastened to the piston of the pneumatic jack ~ 79 by the pressor 10 and it carries integral with it the shanks ,~ 80 which are guided in corresponding vertical axis bushes fixed ;~ to the frame 13 of the machine.
-i~ Underneath the plate 78, the-platform 81 is supported :j by means of the spindles 82 which pass through the plate 78 in ~' sliding fashion, helical compression springs 83 being interposed q between the plate and the platform.
With the lowering of the plate 78 in the direction of ~, the arrow P brought about by the operation of the jack 79, the lid in a flattened configuration rests first of all on the box and a on the products arranged in configuration IV. Subsequently the platform 81 pushes the area 4a of the lid on to the products.
With the further lowering of the plate and whilst the platform 81 is stopped by the products, the said rungs 77 determine first of all the downward folding of the sections 4b-4c, then the rungs 77a fold the flaps 4i-4h-4f-4g forwards and backwards and finally the rungs 77b fold the sections 4d-4e downwards. This folding succession is achieved thanks to the vertical parts of the curved ~ungs 77-77a-77b being of different lengths.
It should be noted that at the exit from the magazine 0~3418 6 a pair of upper glue distribution device 83 are positioned and that these deposit glue on to the upper surface of the $1aps 4i-4h-4f-4g in such a way that when the sections 4d-4e-are folded and pressed on to the aforementioned flaps 4i-4h-4f-4g, so that they remain glued thereto to form the completed lids. Underneath the said glue distribution devices 84, spaced away therefrom a distance e~ual to the thickness of the lid, à pair of further glue distribution devices (not visible on the drawings since they are covered by the distributors 84) are positioned and these attend to spreading the glue on the lower surface of the flaps 4i-4h-4f-4g and the front and rear sections 4b-4c to enable the lid to be secured -to the box. The succession of operational sequences is achieved through the use of electronic detection and control - groups.
The present invention thus makes it possible to rapidly pack products of parallelepiped shape in a way that is practically perfect.

Fig. 3 is a lateral view of the said machine; and Fig. 4 is a plan view of the machine.
With particular reference to the drawings, at 1 there S
is the complete automatic machine designed to pack the parallel-epiped shape product 2 in boxes and lids fashioned out of flattened material 3-4. The material 3-4 is customarily made of corrugated cardboard and is provided with cutting and folding lines which define the central areas 3a-4a, the front, rear and --~
'' lateral sections, 3b-4b, 3c-4c, 3d-3e and 4d-4e, respectively, as well as the flaps 3f-3g, 3h-3i, 4f-4g and 4h-4i. ~-`
~ The machine 1 comprises the magazines 5 and 6 for `~. the boxes and lids in flattened configuration, the line 7 for ., .;
i infeeding the products 2, the pusher 8, the pressers 9 and 10, the infeed line 11 and the set of rollers 12 carried by the frame 13 consisting of a structure of upright members 14, cross members 15a and longitudinal members 15b, welded one to the other.
The magazines 5 and 6 belonging to the boxes and the lids are carried, overhanging fashion, from the support frame 13 by the corresponding frames 16 and 17. Apart from ~heir dimensions, the magazines and the means for moving the individ-ual boxes and lids from the magazines to the utilization zones are virtually identical one with the other, and they are described and numbered cumulatively hereinafter.
The boxes 3 and the lids 4 are arranged one on the other and~ on one side they rest on the rollers 18, and on the other, on the rollers 19, these being carried by the frames 16 and 17, respectively. The rollers 19 revolve first in the direction of the arrow A and then in that of the arrow B, the -lnq34~s purpose of this being to first cause the extremities i-d-f of the cardboard material to be made by the roller 18 to drop on to a cardboard support platform 20 (line in dots and dashes marked I) and then to cause the extremities g-e-h to drop on to the same platform, Underneath the cardboard support platforms are arranged the pairs of gearwheels 21 and 22 around which are wound the chains 23. Between the platform and the upper part of the chain along the frames 16 and 17 are fixed the horizontal ; tracks 24 for guiding the rollers 25 of the carriages 26. To the carriages 26 are articulated the link rods 27 which, in turnr are articulated to the chains 23. As the latter are wound, the -i eyes of the link rods 27 are moved alternately along the upper3 and along the lower portions of the chains and this displaces the ~S carriages 26 alternately in the direction of the arrows C and D.
t Fixed above the carriages 26 there are teeth 28 which pass through corresponding longitudinal flutes in the support platforms 20 and are designed to move the boxes and the lids deposited thereon in the direction of the arrow C and to arrange them in the areas of the machine marked II, with the boxes resting on the support brackets 29. The product infeed line 7 is of the type that consists of an endless conveyor belt 30 mounted over driven ; and idling rollers carried by the frame 31. The latter is pro-vided with lateral guide walls 32 and is supported by an adjust-able height leg 33. A drive group 34 of known type is positioned beneath the frame 31. At the exit from line 7 which infeeds the products 2 in the direction of the arrow E, a pneumatic jack 35 is secured to the frame 13 and this is parallel with the longitu-dinal axis (a) of the machine and has a horizontal piston carrying the pusher 36 which is guided along the two horizontal shanks 37.
As the hack 35 operates in the direction of the arrow F, the said pusher contacts the products in order to carry them into the area 3a of the boxes arranged in position II. A locator 38 is fixed - 4 ~
iO~3418 j to the frame 13 to ensure the correct positioning of the produc~
in the box. In the specific case illustrated in the drawing, ~t is envisaged that products arranged in superimposed pairs are J to be arranged in the box and thus the width of the pusher 36 is slightly less than that of the two closely united products.
At the exit from line 7, the frame 13 has fixed to it the longit-udinal member 39 for locating and guiding the pairs of products coming from line 7 (position 21).
Above area 3a of the box in position II, the machine frame has fixed to it a cross member 40 which is integral with the vertic-~l shaft mounted pneumatic jack 41 whose height, with respect to the cross member 40, is adjustable through a screw ~ -~
:
j connected handwheel 42. Underneath the piston of the jack 41 is ~, fixed the horizontal bracket 43 of the presser 9. The piston is operated alternately in the direction of the arrows G and H, its travel corresponding to the height of the products and its operation in direction G subsequently to the arrival of each pair of products in position 211 causes the products and the boxes to be lowered. Below the bracket 43 is the support bracket 44 which, guided along the vertical shanks 45 and actuated by the jack 46, -~
lowers step-by-step with each operation of the brackets 43. On the sides of the frames are the pairs of members 47 which fold upwards the sections 3b and 3c as the boxes are lowered.
Once a predetermined number of pairs of products have been arranged in the box, the boxes and products are in position III shown with dots and dashes in the drawing, with sections 3b and 3c of the box substantially at right angles to area 3a.
Practically corresponding to the rear edges of the box, the machine frame has articulated to it pivotally the vertical spindles 48 and 49 with which the corresponding spatulas 50 are integral. With the rotation in the direction of the arrows I of the spatulas - the said rotation being achieved advantageously lOq3418 with means of the pneumatic jack type which are not shown on the : drawings - the flaps 3h and 3i are folded forwards in such a way as to render them practically at right angles to areas 3a and 3c.
Under the support platform 51 of the boxes in configuration III
` which extends up to the set of rollers 12, there is a longitudinal ` member 52 which is articulated to the upper extremities of the L
` shaped arms 53 and 54. These L-shaped arms 53, 54 are centrally pivoted to the upright members 55 of the machine and the lower extremity of the arm 53 and an intermediate portion of the lower part of the arm 54 fastened to the spindle 56 which together with the longitudinal member 52 and the arms 53 and 54 forms an articulated parallelogram. The lower extremity of the arm 54 is guided by the cam 57 which is so shaped that its rotation causes the raising and the lowering (arrows L) of the longitudinal mem-ber 52.
Up above the latter is fixed the horizontal track 58 for guiding the carriage 59 which through the connecting rod 60 is linked to the endless chain 61 that turns around the gear-wheels 62 and 63. As the chain unwinds, the rod 60, carried alternately along the upper and the lower portions thereof, causes the carriage 5g to undergo a to-and-fro motion (arrows M-N). The carriage 59 has articulated to it the front extremities of the L shaped arms 64 which carry the idle rollers 65 that rest on the longitudinal members 52. The gearwheel 63 and the cam 67 have one and the same drive and between one and the other the transmission ratio is such that when the carriage moves in the direction of the arrow M, the longltudinal member 58 is dis-placed upwards, whilst when the carriage moves in the direction of the arrow N,` it is displaced downwards. In the latter con figuration, along with the lowering of the longitudinal member 58, the roller 65 is also lowered and the arms 64 are carried into a configuration whereby their upper extremities remain below the lOq3418 platform 51.
During the movement in the direction of the arrow M, . , .'' ' ' 10 - 6a -10'73418 the arms 64 act on the box and its products and cause it to move from position III. On the sides of the frame are positioned converging curved locators 66 which determine the folding back of the flaps 3f-3g to carry them into a condition whereby they are at right angles with the area 3a and the section 3b.
~orresponding to where the locators 66 are to be found `~ on the frame 13, glue distribution devices 67 are mounted and these are designed to spread predetermined quantities of glue on the sections 3d-3e. In order to achieve a faster glue open time, hot melt should ideally be used. Following on after the locators 66 there are tubular locators 68 which, commencing from the ! height of the platform 51, project upwards and converge towards the central area of the platform 51. As the boxes move forward, the locators 68 cause the folding upward of the sections 3d-3e until they are carried at right angles to the area 3a resting ~ against the flaps 3i-3f and 3h-3g, respectively.
j Downstream of the locators 68 there is the set of vertically mounted rollers 12 carried by the frames 69. The latter have integral with them pairs of transverse shanks 70 guided in the horizontal axis bushes 70a fixed to the frame 13, ~` the distance the frames 69 are away from the axis (a) of the machine being adjustable through the handwheels 71 integral with corresponding adjusting screws.
Endless belts a_e mounted around the rollers 12, the latter being held pressing in the direction of the arrows (O) by elastic means of known type in such a way as to press the sections 3d-3e against the flaps 3i-3f-3h-3g and to allow the glue to grip.
The drive group 73 is anchored to the frame 13 and through suitable reduction means, it actuates the gearwheel 63, the cam 57 and the rollers 12.
The boxes now formed around the products continue to move forward in the direction of thç arrow M resting on a set of `, iOq3418 belts mounted around and supported by the transVerse rollers 74 ''~, which are powered in a known ~ashion by the drive group 74a `~ until they trip against the transverse stop 75. The latter is fixed to the piston of the pneumatic jack 75a, the operation of ,~ which is designed to move the stop 75 downwards underneath the :~
plane on which the boxes travel along in order to allow the '~ forward movement subsequent to the arrangement of the lid.
Each individual lid carried into position II by the means described previously in respect of the boxes, is supported ~ 10 in that position by the lateral brackets 76 connected to the curved, j rungs 77 which point downwards and are fixed underneath the plate ~j 78. The latter is fastened to the piston of the pneumatic jack ~ 79 by the pressor 10 and it carries integral with it the shanks ,~ 80 which are guided in corresponding vertical axis bushes fixed ;~ to the frame 13 of the machine.
-i~ Underneath the plate 78, the-platform 81 is supported :j by means of the spindles 82 which pass through the plate 78 in ~' sliding fashion, helical compression springs 83 being interposed q between the plate and the platform.
With the lowering of the plate 78 in the direction of ~, the arrow P brought about by the operation of the jack 79, the lid in a flattened configuration rests first of all on the box and a on the products arranged in configuration IV. Subsequently the platform 81 pushes the area 4a of the lid on to the products.
With the further lowering of the plate and whilst the platform 81 is stopped by the products, the said rungs 77 determine first of all the downward folding of the sections 4b-4c, then the rungs 77a fold the flaps 4i-4h-4f-4g forwards and backwards and finally the rungs 77b fold the sections 4d-4e downwards. This folding succession is achieved thanks to the vertical parts of the curved ~ungs 77-77a-77b being of different lengths.
It should be noted that at the exit from the magazine 0~3418 6 a pair of upper glue distribution device 83 are positioned and that these deposit glue on to the upper surface of the $1aps 4i-4h-4f-4g in such a way that when the sections 4d-4e-are folded and pressed on to the aforementioned flaps 4i-4h-4f-4g, so that they remain glued thereto to form the completed lids. Underneath the said glue distribution devices 84, spaced away therefrom a distance e~ual to the thickness of the lid, à pair of further glue distribution devices (not visible on the drawings since they are covered by the distributors 84) are positioned and these attend to spreading the glue on the lower surface of the flaps 4i-4h-4f-4g and the front and rear sections 4b-4c to enable the lid to be secured -to the box. The succession of operational sequences is achieved through the use of electronic detection and control - groups.
The present invention thus makes it possible to rapidly pack products of parallelepiped shape in a way that is practically perfect.
