Description
W O 97/09255 PCTnT95/00146 A DEVICE FOR THE SUSPENDED TRANSPORT OF CONTAINERS
POSSESSING PROTRUDING COLLARS.
DESCRIPTION
The object of the present invention is a device capable of transporting containers with protruding collars by their suspension therefrom.
There is a widespread use of air driven transporting 05 devices for the transport of plastic and non-plastic containers possessing protruding rings around the area of the neck, typically bottles made from PVC, which require the use of supporting guides on which the protruding collars are placed. They are then moved by a series of fans placed at intervals of about 5 to 7 metres one from the other and designed to blow air in the direction of transportation.
The drawback of this system however, is that the fans set in motion large quantities of air often resulting in the pollution of the containers.
A further drawback is the considerable noise level generatedJ the elevated power installation and the high levels of energy consumption.
The Italian patent for the industrial invention N. 1190535 shows a mechanical apparatus for the forward movement of suspended plastic bottles in which a transporting belt W O 97/09255 PCTnT95/00146 extPn~ing over the whole distance of the transport is equipped with a bottle carrying mechanism which att~rh~c itself under the bulge in the neck of the bottle susp~nAing and transporting it through a guiding rh~nn~l 05 extended along the length of the transport.
The above mentioned document anticipates, for the means providing the forward movement, the use of devices which pOcc~cq at least one mechanical dragging mechanism which grasps the bottles to be transported and which can be made up of the lateral marginal band of a ~ollveyor or cable transporter or a series of pl~ching elements acting on the area of the bottle opening above the collar.
The above mentioned devices have not, ho./_ver~ found a practical application in that they pose numerous difficulties above all in curved or uphill tracts of the transport system.
In fact the transport systems described envisage a motorised element, typically a belt or strap combined with a further element (for example, a rubber coated belt) which interacts with the collars of the cont~iners. This last element is not coaxial with, or anyway detached from the motorised element so that, in the curved parts of the transport, it describes a different curve from that of the motorised element. It is obvious that this gives rise to numerous operating problems in the setting up, tensing and the calculation of the dimensions of su_h tr~nspo~terS.
Another conveyor which uses pushing mechanisms is that described in the Italian patent app~ication No. 40029A/90 in which the use is envisaged of the move~ent of the 05 active branch of a closed chain fitted with lateral elastic protruding pushing elements to one side of the containers and positioned next to a pair of longitudinal guiding elements.
Should there be an accumulation of containers however, as a result of the stopping of the machine do~n stream, this then generates a high noise level and may cause damage both to the pushing elements and to the containers derived from the sliding force which continues to be exerted by the pushing elements on the containers.
US-A-3 934 99~ discloses a glassware handling and treating equipment in which glass bottles are conveyed along a straight path by means of two parallel endless chains pro~ided with grippers constituting spring fingers that are justaposed and biased toward each other to engage the necL~ of the bottle, ~hich it is suspended from the endless conveyor chain.
This document has the same drawbacLcs already cited above, because does not consent to convey the bottles on curved paths and may damage the bottles if there is an accidental stop of the bottle flow.
The purpose of the present invention is to eliminate the above difficulties and in particular to make available a conveyor for the suspended transport of containers with protruding collars which will continue to function in curved and up-hill sections of the transport, thus being capable of the effective replacement of the transportation systems using air as their motive force, with a significant reduction of energy consumption and power installation and without problems arising from the accumulation of containers in the event of a halting of the transport movement.
AMEN~D SHEET
W097/09255 PCT~T95/00146 The said aims are completely fulfilled by the transport device being the subject matter of the present invention, characterised by the descriptions appearing in the claims set out below, and in particular, in that the path 05 followed by the marginal extremity of the pulling elements for the contAin~rs is substantially identical (having as well, the same curvature) as that described by the motorised elements of the device, kinetically ronnPrted to the said pulling elements and positioned at a different level from the latter.
These and other characteristics are to be seen more clearly from the following description of two preferred ~hodiments, the same to be taken purely as non limiting examples, as illustrated in the attArheA drawings in which:
- Figures 1) and 2) illustrate the device in a view which is partially sectioned along the axis of movement according to two different embodiments;
- Figure 3) illustrates the device in a lateral view substantially perpendicular to that of Fig.1);
- Figure 4) illustrates a view of the device from above which is partially sectioned along the line A-A in Figure 3);
- Figure 5) illustrates the device in a view from above in a curved section of the transport device.
W097/09255 PCT~T95100146 Referring to Figure 1, 1 indicates in detail a cont~ining frame or guide for a chain ~o-~e~or made up of a pair of roller-type closed rh;~i nc 2 which move in a plain which is substantially horizontal or with an inclination of less 05 than 20 degrees transversally to the direction of movement, and with even greater inclination along the direction of movement in parts where the transport rises or descends.
Att~rh~ ~y the use of appropriate means 10 which could be, for example, screws, to the guide 1 is a counter-guide 4, for the purpose of supporting the ch~ins and of creating a movement rhAnnel for them between the guide and counter-guide.
The roller rhAinc 2a and 2b are moved in the direction indicated by the arrows 8 by a motorization not illustrated because being of known type and which moves the ch~inc by means of for example, pulleys fitted flush to rotating shafts and the rh~inc then being wound round the said pulleys.
Rollers 3, which constitute first mobile elements, are fitted from beneath with supports 7 in the form of a "C", thus making up second elements on whose lower extremities 7a the protruding marginal area of the collar 6 of each cont~in~r 5 is placed, axial to the central rods of the said rollers. The supports 7 are in fact, anchored from W O 97/09255 PCT~T95/00146 above to the rollers 3 of the ~hAin~ and are shaped in such a way that their active lower extremity 7a providing support for the contAiner is arranged so that it substantially forms part of the same plane passing through 05 the axes of the correspon~ing pair of rollers to which the support 7 is connected. Each support 7 is connected to a pair of rollers 3 of a chain. With the support 7 set up in this way, the path followed by the active lower extremitiy 7a functioning as supports and transporting mechanisms, is substantially identical to that of the rollers of the relevant chain, with an identical curvature.
In this way it is possible to eliminate all difficulties arising during the use of the traditional devices in curved sections of the transport in that, with the use of the present device, the path described by the first mobile elements, namely the rhAins, is completely identical to that of the lower extremities 7a in such curved sections.
To obtain such a result, the plane through which the contAiners move (the plane described by the motion of the relative collars), marked as 9 on the Figure 1, has been moved down, positioned below the plane through which the rh~ i nC move.
The particular arrangement of guide 1 and counter-guide 4 results in a significant increase in the rigidity of the W097/09255 PCT~T95/00146 - structure of the device and avoids unwanted flexing of the supports 7 and in addition, makes the device easy to adapt to cont~inPrs with neck and collar of differing diameter.
It is easy to envisage the use of a plurality of blocks or 05 spacers to insert into the interior of the partitions la of the guide to reduce the width of the central ch~nn~l ll, and another series of corresponding removable spacers from the counter-guide 4 to reduce its lateral dimension.
In the variant model illustrated in Figure 2 there is no counter-guide 4 and the ch~inc are fitted with supporting elements 12 from above, anchored to the rollers and running over a milled seat interior to the guide l with the function of sust~ining the chain.
According to a further embodiment not illustrated here, it is possible to envisage, for both solutions pl~O--~ in Figures l and 2, the use of a single chain 2 fitted with mobile supports 7 coupled with a fixed supporting guide to the collars on the opposite side.
With particular reference to Figure 4, the part of the extremity 7a marked 71 is ch~r~ substantially in the form of an isosceles trapezoid while joined to this is a part marked 72, substantially rollnA~A in form.
~he said shape of the extremities or appendices 7a of each supporting element 7 creates a unified support surface for the protruding collars of the cont~in~rs at both sides W097/09255 PCT~T9S/00146 of the collar, and allows the preservation of the level continuity of such a surface even in curved sections where the continuity is maint~ine~ th~nk~ to the partial overlap of the trapezoidal part of a support with the rounded part 05 of the support immediately following.
The part in the form of an isosceles trapezoid 71 has its longer side facing the central ch~nn~l 11 through which the cont~iners 5 are moved.
It is obvious that the chain col-v~ors 2 can be replaced by other types of ~u"ve~ors, for example driven by belts or cables to which supports have been attached in such a way as to present an active supporting extremity for the cont~iner, describing a substantially identical path in curved sections to, and with the same curvature as, that described by the initiating driving element of the co"~e~or, wether belt or cable.
The term "substantially identical" is used to describe a path of the extremities 7a which is co-axial to that of the transport, or having the same curvature, at least with lateral play of less than 20mm.

AMEN~D SHEET
W097/09255 PCT~T95/00146 The said aims are completely fulfilled by the transport device being the subject matter of the present invention, characterised by the descriptions appearing in the claims set out below, and in particular, in that the path 05 followed by the marginal extremity of the pulling elements for the contAin~rs is substantially identical (having as well, the same curvature) as that described by the motorised elements of the device, kinetically ronnPrted to the said pulling elements and positioned at a different level from the latter.
These and other characteristics are to be seen more clearly from the following description of two preferred ~hodiments, the same to be taken purely as non limiting examples, as illustrated in the attArheA drawings in which:
- Figures 1) and 2) illustrate the device in a view which is partially sectioned along the axis of movement according to two different embodiments;
- Figure 3) illustrates the device in a lateral view substantially perpendicular to that of Fig.1);
- Figure 4) illustrates a view of the device from above which is partially sectioned along the line A-A in Figure 3);
- Figure 5) illustrates the device in a view from above in a curved section of the transport device.
W097/09255 PCT~T95100146 Referring to Figure 1, 1 indicates in detail a cont~ining frame or guide for a chain ~o-~e~or made up of a pair of roller-type closed rh;~i nc 2 which move in a plain which is substantially horizontal or with an inclination of less 05 than 20 degrees transversally to the direction of movement, and with even greater inclination along the direction of movement in parts where the transport rises or descends.
Att~rh~ ~y the use of appropriate means 10 which could be, for example, screws, to the guide 1 is a counter-guide 4, for the purpose of supporting the ch~ins and of creating a movement rhAnnel for them between the guide and counter-guide.
The roller rhAinc 2a and 2b are moved in the direction indicated by the arrows 8 by a motorization not illustrated because being of known type and which moves the ch~inc by means of for example, pulleys fitted flush to rotating shafts and the rh~inc then being wound round the said pulleys.
Rollers 3, which constitute first mobile elements, are fitted from beneath with supports 7 in the form of a "C", thus making up second elements on whose lower extremities 7a the protruding marginal area of the collar 6 of each cont~in~r 5 is placed, axial to the central rods of the said rollers. The supports 7 are in fact, anchored from W O 97/09255 PCT~T95/00146 above to the rollers 3 of the ~hAin~ and are shaped in such a way that their active lower extremity 7a providing support for the contAiner is arranged so that it substantially forms part of the same plane passing through 05 the axes of the correspon~ing pair of rollers to which the support 7 is connected. Each support 7 is connected to a pair of rollers 3 of a chain. With the support 7 set up in this way, the path followed by the active lower extremitiy 7a functioning as supports and transporting mechanisms, is substantially identical to that of the rollers of the relevant chain, with an identical curvature.
In this way it is possible to eliminate all difficulties arising during the use of the traditional devices in curved sections of the transport in that, with the use of the present device, the path described by the first mobile elements, namely the rhAins, is completely identical to that of the lower extremities 7a in such curved sections.
To obtain such a result, the plane through which the contAiners move (the plane described by the motion of the relative collars), marked as 9 on the Figure 1, has been moved down, positioned below the plane through which the rh~ i nC move.
The particular arrangement of guide 1 and counter-guide 4 results in a significant increase in the rigidity of the W097/09255 PCT~T95/00146 - structure of the device and avoids unwanted flexing of the supports 7 and in addition, makes the device easy to adapt to cont~inPrs with neck and collar of differing diameter.
It is easy to envisage the use of a plurality of blocks or 05 spacers to insert into the interior of the partitions la of the guide to reduce the width of the central ch~nn~l ll, and another series of corresponding removable spacers from the counter-guide 4 to reduce its lateral dimension.
In the variant model illustrated in Figure 2 there is no counter-guide 4 and the ch~inc are fitted with supporting elements 12 from above, anchored to the rollers and running over a milled seat interior to the guide l with the function of sust~ining the chain.
According to a further embodiment not illustrated here, it is possible to envisage, for both solutions pl~O--~ in Figures l and 2, the use of a single chain 2 fitted with mobile supports 7 coupled with a fixed supporting guide to the collars on the opposite side.
With particular reference to Figure 4, the part of the extremity 7a marked 71 is ch~r~ substantially in the form of an isosceles trapezoid while joined to this is a part marked 72, substantially rollnA~A in form.
~he said shape of the extremities or appendices 7a of each supporting element 7 creates a unified support surface for the protruding collars of the cont~in~rs at both sides W097/09255 PCT~T9S/00146 of the collar, and allows the preservation of the level continuity of such a surface even in curved sections where the continuity is maint~ine~ th~nk~ to the partial overlap of the trapezoidal part of a support with the rounded part 05 of the support immediately following.
The part in the form of an isosceles trapezoid 71 has its longer side facing the central ch~nn~l 11 through which the cont~iners 5 are moved.
It is obvious that the chain col-v~ors 2 can be replaced by other types of ~u"ve~ors, for example driven by belts or cables to which supports have been attached in such a way as to present an active supporting extremity for the cont~iner, describing a substantially identical path in curved sections to, and with the same curvature as, that described by the initiating driving element of the co"~e~or, wether belt or cable.
The term "substantially identical" is used to describe a path of the extremities 7a which is co-axial to that of the transport, or having the same curvature, at least with lateral play of less than 20mm.
