Description
1~3~
This invention relates apparatus for the transfer and transport of items such as open-encled cans from a treat-ment station onto a conveyor means.
Individual items such as open-ended cans, at times, are required to be transferred from a treatment station, for e~ample, from a station providing a decoration, such as, for example, a surface lacquer finish, a surface printing or the like surface treatment, onto a conveyor for further transport to ano-ther treatment station or the like.
It is known to transport cans with an open end and a closed end, often produced by a suitable wall-forming operation, by means of a chain conveyor means having supporting pegs or pins which reach into the interior of the cans, through the open end thereof. Thus, the cans are freely suspended or pen-dently supported on the pegs or pins. In order to provide a surface printing or lacquer finish on the outer cylindrical walls of the cans, they are transferred onto the pegs of ro-tating peg wheels which coact with the printing tools or lacquering equipment, respectively. Each peg wheel is comprised of a rotatably mounted disc and a plurality of pegs is locatec' in a circular pattern on one surface of the disc, each peg pro-truding substantially perpendicularly from that surface. In the case of surface printing, these pegs are adapted to carry out radial movements in order to adapt the movement of the cans during printing to the mo-tion of the printing cylinder, use being made of complex mechanisms and curve con-trol means for such radial movements; and to facilitate, during the reception and release of cans by corresponding radial movements, the acti-vation and deactivation of pegs, during reception on and re-moval of cans from the peg wheel.
". , ,.~ .
~3~
In the known apparatus, the removal of the cans from the peg wheel is achieved by a further chain conveyor means with pegs, whereby the cans are removed from the peg wheel, during movement of the peg wheel, either by a transfer mech-anism provided for each peg, or by means of an intermediary transfer wheel having translatory movable suction means. The cans are then transferred to be transported by a conveyor means for further transporting, this conveyor means again having pegs. These known installations for the removal and further transporting of the cans are very complex and struc-turally very bulky. A high manufacturing precision thereof is necessary and fine-tuning requires large amounts of time, since the installations have to operate accurately at the pre-sently required throughput rate of 600 to 1,000 cans per minute. Due to the very fast movement required for the trans-fer of cans by movable parts, in part incorporated into the peg wheel, this high throughput rate causes a relatively high wear and considerable maintenance efforts which add to the overall costs.
It is an object of the invention to provide an apparatus with which the removal and further transporting of the cans, which are supported on the pegs of the peg wheel for surface finishing, e.g., printing or lacquer finishing, is substantially simplified and which eliminates complex trans-fer mechanisms, whether such transfer mechanisms are in the form of transfer units incorporated in the peg wheel, or in ` the form of separate transfer wheel means.
In accordance with the invention, there is provided an apparatus for the transfer and transport of cans from a station in which the cans are subjected to a treatment step.
The station includes a rotating wheel having pegs on which the open ended cans are supported. The pegs are spaced apart circumferentially on one face of the wheel. A f:irst conveyor means is provided at a distance greater than the height of a can to be transferred from a respective peg on the rotating wheel onto the first conveyor means. The conveyor means has a flat supporting surface for receiving the bottoms of the cans, and the surface extends substantially parallel with respect to the plane of the rotating wheel and at least part of this surface extends oppositely with respect to a portion ~ -of the path of the cans on the rotating wheel. Nozzle means are associated with the wheel for the provision of a fluid jet to transfer a can from a respective peg axially onto the surface. Means to provide a retention force on the bottoms of the cans is associated with the first conveyor such that when the cans are transferred onto and in contact with the surface of the first conveyor, they are retained as they are being advanced.
It has, surprisingly, been found that the removal of cans from the peg wheel and the transfer onto a conveyor tan-gentially disposed with respect to the peg wheel is possible, when the cans are blown off the pegs of the peg wheel and, upon landing on the mounting surface of the conveyor means, are held by an adequate retention force, e.g., by means of a magnet or by the suction of a negative pressure. Practice has shown that by a correct adjustment of the pressure of the removal/blowing and the corresponding retention force exerted on the can on landing on the conveyor, the cans can be trans-ferred in a very uniform manner onto the conveyor and they also ; follow the path of motion of the further transporting conveyor without carrying out a relative movement with respect to the conveyor.
So-called magnetic or suction conveyors are known E~
se, as well as the arrangement of discharge nozzles in combin-ation with peg wheels, so as to facilitate the transfer of ~' - 3 -8~L
cans, ~or example, in the case of transfer wheels, onto the suction means of the translatory mova~le, by means oE the transfer wheels, SUCtiOII means, or in order to brid~e part of the transfer distance of the cans onto the suction means by means of the air pressure. ~7hile in present usage o magne-tic or pneumatic conveyors, as ~well as the usa~e of discharge nozzles, in the transfer of cans from a transport element to another, additional auxiliary means were required in order to transfer the cans onto the path of a conveyor, and to impart to the cans the velocity determined by the conveyor, in the case of the present invention no additional means are required, but merely by the interaction of the said nozzle means and the con-veyor tangentially joining the path of the cans on th~o peg wheel, the transfer and synchronized further transport of the cans, with simultaneous change of direction of motion on the further transport conveyor, are achieved.
The conveyor carrying out further transport of the cans can also be in the form of an intermediate conveyor, in order to direct the cans ayain to a chain with pegs, or a fur-ther magnetic means or suction means comprising conveyor so as to direct the cans, for example, to a drying oven.
It is useful that the conveyor, positioned in parallel with respect to the plane of the peg wheel, be in the form of an endless band conveyor.
In many cases, however, it is not possible, particu-larly in the si-tuation of existin~ printing machines, to arrange band conveyors to extend in parallel with respect to the plane of the peg wheel, which conveyors are joined direct-ly to the peg wheel, because, for example, -the conveying di-r~ction is not ~avorable, or, the arrangement of the removal .
~33~8~
conveyor is not feasible due to limitations in space in this area. In such cases, in accorclance with a particular embodiment of the invention, the conveying means arranged in ~arallel ~ith respect to the plane of the pin wheel can be in the form of a rotatably mounted disc, which is followed then again by a tangentially disposed endless belt conveyor, co-acting with a magnet or a vaceuum providing means. In view oE the arrangement of a rotatably mounted disc, which coacts, as hereinbefore described, with a magnet or a vacuum provi-ding means, in the same manner as is the case with a band conveyor, any desired change of the cdirection of movement of the cans ean be achieved, that is up to and ineluding to the complete reversal of the direction of movement, relative to tneir direction of movement at that point in time of their transfer from the peg wheel onto the rotatably mounted disc.
The transfer oE cans onto the ro-tatably mounted disc nas also been proven in praetice and provides the opportuni-ty, as in the case of the further transport by means of a band conveyor, to vary the distance be-tween the cans, in eomparison to their distance of separation on the peg wheel, in order, for example, to achieve a greater or lesser density of cans on t~e conveyor for further transporting~
Embodiments of -the invention are illustrated in the drawings in which:-FIG. 1 illustrates a peg wheel and an assoeiated con-veyor for further transporting, in the form of an endless band conveyorl for receipt oE the cans and the fur-ther -trans-porting thereof, after they have been printed, while being supported on t:he peg wheel;
FIG. 2 shows a modified arrangemen-t of the embodiment in accordance with FIG. 1, wherein further transport of cans, ~ ~3;~4 transferred rom the peg wheel ~nto the band conveyor, is achieved by means of a chain havinq carrying pins; and FI~. 3 illustrates a peg wheel with an associated rotatably mounted disc forming the transfer conveyor for the cans for transfer to a conveyor for the further transport, in the form of an endless band conveyor.
In the drawings, a peg wheel 1 is scher~atically repre-sented by a circular pitch line on which a plurality of pegs 2 is provided and which peg wheel can be ro-tated i~ the clirec-tion of arrow 3, i.e., in clockwise direction.
Cans 10 having an open end and a closed end arebrought onto the pegs 2 by means of a transfer equipment and delivery conveyor, both not shown. On the righ-t hand side thereof, the peg wheel 1 cooperates with a printing apparatus or lacquering station, not shown t SO that the cans are printed or lacquer finished on their respective cylindrical outer sur-Eaces during the comovement on the pegs 2 of peg wheel 1.
On removal of the cans 10 Erom the pegs 2 of the peg wheel 1, and during -the subsequent transport thereof to a drying station, no-t shown, the freshly printed or lacquered surfaces must not come into contact with each other or with other objects. Thus, the cans 10 can only be handled by their open or closed ends or by insertion of pegs into the in-terior of the cans until drying of the printing or lacquer finishing, respectively, is completed.
In -the embodiments shown and described, there is pro-vided for thi, purpose a further conveyor, at a distance cor-responding at:Least to the height of a can and parallel with respect to the plane of movement of the peg wheel 1. This conveyor for further transportinq is equipped with a magnet or a ne~ative pressure source or chamber, for the provision of a retention force for holding the can and the conveyor has a mounting surface for the cans, to be transferred from the pegs 2, so that the cans are retained with their respective closed ends on the mounting surface. The cans can be further transported by means of the receiving conveyor.
Transfer of -the cans 10 from the peg wheel 1 is achieved by the pressure of a discharge jet directed into the interior of the cans in the direction of arrow 4, using schematically represented discharge nozzle 11. ~he mounting surface of the conveyor onto which the cans are brought, due to the jet of the installation, is provided tangentially with respect to the path of the cans on the peg wheel 1.
In the embodiments shown in FIG. 1 and FIG. 2, the mounting surface for the cans is provided by an endless band conveyor 6 which is driven by means of s drive roller 7, name-ly, in the direction of arrow 7a, i.e., counterclockwise. A
section 6a of the conveyor, which section forms the mounting surface and which is facing towards the peg wheel 1, is gui-aed on a stationary magnet 8, the magnet extending in the direction of the section 6a, so that the cans 10, on transfer thereonto, from the peg wheel 1, in the direction of arrow 5, at the moment of impact on the mounting surface of the sec-tion 6a, are held by magnetic attraction and are then further transported in order to be directed, in the direction of arrow 9, either to yet another conveyor, for example, a chain having pegs, or another band conveyor having retaining magnets.
Conveying bands equipped with magnets are, of course, only suited for cans made of a ferromagnetic material. In the case of cans which are made of aluminium, instead of the mag-net 8, a corresponding vacuum chamber can be provided in con-junction with an endless conveyor, for example, a belt con-~ .

In the case of cans which are made of aluminium, instead of the mag-net 8, a corresponding vacuum chamber can be provided in con-junction with an endless conveyor, for example, a belt con-~ .

veyor having passages for the vac~um in orcler to retain thecans by means of the vacuum on the conveyor for further -trans-port.
An embodiment showing the transEer of cans Erom the conveyor 6 on-to a chain having pegs is shown in FIG. 2. Thus, it will be seen that chain 17 with pegs 16, moving in the di-rection of arrow 12, is guided ,around sprocket turns 13, 14 and 15, whereby, in the region between the sprocket turns 14 and 15, the transfer of cans 10 onto the pegs 16,of chain 17 13 is achieved. For this purpose, the lateral distance of the sprocket turn 14 from the section 6a of the endless conveyor 6 is greater than the distance at sprocket turn 15. On the path of the pegs 16 from the sprocket turn 14 to~ards the sprocket turn 15, the pegs 16 are inserted into the cans which are held on the section 6a and they remove the cans at the end of magnet 8 from the section 6a and carry the cans in the direction of the movemen-t of the chain 17, whereby the chain is directed, in the direction of arrow 18 towards a drying station, not shown, whereby the chain assumes a position, somewhat skewed, so that the cans, due to gravity, are se-curely supported on the pegs 16.
ln the embodiment shown in FIG. 3, the mounting sur-face for the cans 10 which have been blown off the pegs 2, by means of a discharge nozzle 11 in -the direction of arrow 5, is provided by a rotatably mounted disc 19, rotatably in the direction of arrow 20, i.e., counterclockwise. The disc 19 is arranged in front o~ a stationary magne-t 21 which is adapted to the diameter of the cliscl9, so that the cans 10, at the moment of impact on the disc 19, are retained by magnetic attraction and are then moved through -the arcuate path pre-scribed by the disc 19. In this manner, they reach a sec-~ ~32~
tion 22a of an endless conveyor 22 which, in the embodimentshown and described, is in the form of a belt conveyor and the section 22a thereof, again, is moved in front of a sta-tionary magnet 23. The direc-tion of travel of conveyor 22 is indicated by -the arrows 23 and 2~.
The disc 19 is arranged with respect to the path of motion of the cans 10 on the peg wheel 1 such that the section of the mounting surface, onto which the cans are trans-ferred due to the jet pressure, is extending tangentially with respect to the path of movement of the cans 10 on the peg wheel 1.
Again, the magnetic retention described with respect to the embodiment of FIG. 3 can be replaced by appropriate vacuum means in association with suitable perforated mounting surfaces of the associated conveyors, in the event that the cans are not made of a ferroma~netic material, but of a para~ or non-magnetic material.
It has been surprisingly found that alone by the pressure which is exerted by the jet emanating from the dis-charge nozzle, in conjunction with the conveying means descri-bed, which exert a retention force on cans transferred by means of the jet, by a tangential arrangement of the mounting surEace in the transfer region, a removal and reception and further transport of the cans can be achieved without notice-able deviation with respect -to separating distance between the cans and i.n the positioning of -the cans, so tha-t transfer of the cans from the receiving conveyor -to the conveyor for further transport can be carried out. Furthermore, one can select -to reduce the distance between cans by means of regu-lating the velocity of the receiving conveyor or to increasethe distance, depending on specific requirements. Thus, for , example, it is possible to move the cans to a drying s-tation after they have been removed from the peg wheel 1, solely by means of magnetic conveyors in a closely following order and thereby to arrange the cans with ~nown equipment for transfer into the dryin~ oven.
