Abstract
ABSTRACT OF THE INVENTION
The invention relates to a method of and an apparatus for transporting flexible foil packages, parti-cularly flat bags (6, 8, 13) filled with unstabilised material to a package container (1). The flat bags (6, 8, 13) deposited flat and with uniformly distributed con-tents by a filling and closing machine upon a transport belt are first of all imbricated and maintained clamped on both sides during further transport into the package con-tainer, so that the uniform distribution of the contents is maintained into the container. A close filling of the container (1) without excessive pressure is ensured by this means. Because the flat bags are conveyed from the conveying path directly into the container without an intermediate magazine, containers of different size can be filled consecutively virtually without interrupting the conveyance. It is therefore possible, in the case of parallel operation of a plurality of similar lines, to operate filling machines of different capacity each at maximum capacity, in order to assemble containers which are filled with the flat bags delivered by the different filling machines into larger assorted units, without the different capacity leading to an excess supply of con-tainers at the collecting station, where the containers are assembled to form the units. The surplus capacity of one or the other machine is in fact compensated by locking in other package containers into the one line and subsequently withdrawing the filled containers.

7~7 PACKAGES, PARTICULARLY FLAT BAGS, FILLED WITH POURABLE
OR FLOWABLE MATERIAL TO A PACKAGE CONTAINER FORMING A
STACKING STATION
BACKGROUND OF THE INVENTION
Field of the Invention The invention relates to a method of transporting flexible foil packages, particul3rly flat bags, ~illed with unstabilised, part;cularly pourable or flowable material, to a package container forming a stacking station, whereby the bags arriving flat in a consecutive row and containing the contents in a distributed manner are transported from a horizontal conveying path section via an arcuate conveylng path section to a f;nal vertical conveying path sect10n extending to the stacking station, upon ~hich the bags are reta;ned clamped on both s;des during the transport.
Discussion of Prior Art In order to acco~modate flexible foil packages, part;cularly flat bags, filled with unstabilised material, part;cularly pourableror flowable material~ as closely as possible in package containers, cases for example, but _ without excessive pressure on the contents, (risk of damage to the contents, soups or fragile chips for example), the material present on one side in the bag after the filling operation and closure is distributed uniformly over the entire bag by agitation, so that the bag transported flat along the first hori~ontal eonvey;ng path section has only a comparatively low he;ght. The flat bags with the contents thus distr;buted, on their further conveying ` ~S~7 1 route, after pass;ng an arcuate sloping convey;ng path~
enter the final almost vert;cal conveying path sect;on, in which they are reta;ned clamped by conveyor belts arranged oppositely. These conveyor belts end above a magazine d;v;ded into compartments, in wh;çh magazine the bags are mutually aligned. As long as the bags are retained cLamped between the conveyor belts on bot~ sides, the unîform distribution of the contents is maintained.
However, after leaving the conveyor belts the bag contents can shift towards the lower edge of the bag again. This shifting is further promoted by the fact that the bags strike the floor of the magazine at unreduced conveying speed, so that the contents also accumulate at the lower edge of the bag for this reason. Due to this one-sided 1S shi~ting of the contents, the compact filling o~ the pack-age container with such bags is not ensured, or the bags are pressed too hard, wh;ch leads to damage to the con- ¦
tents. Furthermore, the bags are shock-stressed again after the transfer of the bags present in the magazine into the package container. Furthermore, the preliminary sorting in a magazine and the transfer into the pack-age container restrict capacity. Lastly, this prelimin-ary storing of the bags is restricted to a specific size of the package container. A particular preliminary magazine has to be made available for each container size.
SUMMARY oF THE INVENTION
....
The underlying object of the invention is to develop a 0ethod of transporting flexible foil packages filled with unstabilised material to a package container~ wh;ch permits a close packing of the foil pàckages without excess;ve pressure upon the contents~ The filling of the package containers should then be possible without maltreat-;ng the contents but w;th a r,igher capacity than hitherto.
` ~;25~77 -3-~
The invention provides a method of filling and transporting containers with filled packages, which comprises the steps of providing flexible filled packages at a plurality of adjacent container filling stations by transporting said packages in a substantially horizontal path, contents of said packages being substantially uniformly distributed, transporting said filled packages further in a downward sloping path for depositing into containers while maintaining substantial distribution un-iformity of said package contents, transporting empty containers of different dimensions for said filled packages to each container filling station from firs~ and second empty container supply stations, filliny the containers with the flexible packages while maintaining substantial distribution uniformity of package cont-ents, transporting said containers filled with packages from the container filling stations to a common collecting station for filling further containers with said containers filled with packages from the adjacent container filling stations.
The invention also provides an apparatus for filllng and transporting containers with filled packages, which comprises a plurality of adjacent container filling stations, said adjacent container filling stations comprising first conveying means for transporting the filled packages in a substantially horizontal path, the contents of said packages being substantially uniformly distributed, second conveying means for receiving filled packages from the first conveying means and for transporting said packages in a downward sloping path for depositing into containers, said second conveying means including means for maintaining substantial distribution uniformity of package contents, first and second ~ z5~ 7~7 -3a ~ ~
empty container supply stations, independent conveying means for transporting containers of different climensions from said fixst and se~ond empty container supply stations to said adjacent container filling stations for filling with said filled packages while maintaining distribution uniformity of package contents, a common collecting station for the filled containers, third con-veyor means for transporting filled containers from said adjacent container filling stations to said common collecting station, and means for filling further containers with said filled con-tainers at said common collecting station.
Preferably the packages are imbricated, and in the container each package is guided on its side facing the package stack by the packages already forming the stack and :is exposed to forces of conveying effect on its side remote from the stack.
Imbrication of the packages has the dual effect that firstly the transport speed is decreased without reducing capacity, and the shock forces at the end of the conveying path are also reduced, and on the other hand the foil packages guide themselves in the package container. Any intermediate sorting in a magazine is therefore eliminated.
Whereas in the known methods the packages are thrown against the container bottom at indefinite speed, whilst they have no front or rear guidance, in the invention they are transported at a precise conveying speed to the bottom of the container, whilst they are braced at both their front and rear :~2~7~
-3b-sides, so that the material distributed uniformly in the pack-age cannot shift to one side. In this manner a close filling of the package container with packages is ensured, without the contents of the packages being thereby exposed to undue compress-ive stresses.
A favourable effect is produced upon the operation of filling the package container with packages if the container is advanced solely by the packages conveyed into the container.
In this case the container should be capable of being slid upon a stationary base. In such a case the weight of the container becomes greater, and the dynamic pressure correspondingly greater, with increasing filling. This is favourab:Le because when only a few packages have been filled into the package container the dynamic pressure should be as weak as possible, because :~2~ 7 1 otherwise there ;s a danger of the indiv;dual container be;ng compressed unduly and the contents might then be damaged. However, when there are a large number of pack-ages in the conta;ner a la'rge elast;c cush;on is present 5 which compensates for any excessive compression of an.
indiv;dual fo;l package.
It occurs frequently in pract;ce that foil pack-ages are f;lled w;th d;fferent contents and/or that fo;l packages of different d;mensions are filled, and that package un;ts ~assortments) are assembled from such fi~led fo;l packages. The assembly is effected from a plural;ty of containers w;th the same dimensions, wh;ch are f;Lled w;th fo;l packages of different contents and/or of differ-ent dimensions from conta;ner to conta;nern However, 15 the parallel operat;on of d;fferent f;lling and clos;ng mach;nes and packag;ng mach;nes for the foil packages w;th ! d;fferent contents and/or d;fferen-t d;mens;ons ;s not ;mmed;ately poss;ble for various reasons. The filling and closing mach;nes generally operate w;th a different 20 capacity. This means that the filling t;me into contain-ers of the same size ;s different for the fo;l packages delivered by the var;ous f;ll;ng and closing mach;nes.
; The output of filled containers may also be dictated by a machine stoppage due to a fault or to a change of foils.
25 Lastly~ a different fill;ng time for the conta;ners may also be d;ctated by the contents or by d;fferent d;men-sions of the packages. In order to prevent an excess;ve _ -over-supply of the containers with packages one or the other type during assembly, the high-output mach;ne may be adapted to the lowest-output machine by throttling. How-ever, this type of adaptation leads to a reductiori in capac;ty in the overall performance of the filling and closing machines and packag;ng machines.
A further claim of the invention therefore is to assemble foil packages with different contents and/or 4~7~7 1 different dimensions ;nto assorted package un;ts and at the same time to operate with maximum capacity on each line of the machines operating in parallel.
According to one development of the invention, i this object is achieved in that package containers are filled with foil packages of different contents and/or different dimensions in a-plurality of parallel lines, whilst empty package containers, which are moved selec-tively from one or the other transport path to the fill~ng station~ are fed to the filling stations via two transport paths each for one type of package container~ and from each f;lling station the filled package containers of the one type are transported via a transport path to a collec-ting station, and the filled package containers of the other type are transported from all the filling stations via further transport paths to a common collecting statlon, where the package containers which contain the foil pack-ages filled with different contents and/or of different dimensions are combined to form package unitsD
In the method according to the invention, the surplus capacity of the strongest line is moderated rela-tive to the weaker lines in that a package container of the one type is locked in repeatedly and intermittently and filled with foil packages at the filling station and transported away again when a sufficient supply of filled package containers of the other type exists at the collec-ting station to assemble package units from them. The -- -filling of package containers of different types with foil packages is poss;ble virtually w;thout interrupting the conveyance of the foil packages to the filling station, because the foil packages pass from the vertical conveying path directly into the containers and do not enter the package containers via an intermediate accumulator, such as a magazine. The method according to the invention ¦ i~
therefore permits lines of different capacity to be 1 coordinated without throttling the capacities of the stronger lines.
A suitable apparatus for perforMing the method, according to the invention, of transport;ng foil packages to a package container consists of a first conveying path section, oriented substantially horizontally, having supporting transport means for ~he foil packages arriving flat in a consecutive row and filled with unstabilised, particularly pourable or flowable, uniformly distributed ma~erial, and of a further conveying path section extend;ng from the hor;zontal arcuately into the ver~;cal to the stacking station and having transport means clamping the foil packages on both sides. According to the invention, this apparatus is characterised in that a second convey-ing path section for imbricating the fo;l packages is arranged between the first and the further conveying path section, and that of the transport means clamp;ng the foil packages, only one transport means extends above the stack to be formed ;n the conta;ner.
Accord;ng to one development of the invention, that part of the transport means extend;ng above thestack to be formed forms an abutment r;g;d in the direc-t;on of the stack axis, w;th which the pillar formed by the wall of the package container slidable on a base and 25 receding with increasing stack height is associated on the oppos;te side of the stack. The we;ght of the pack-age conta;ner increas;ng with progressive f;lling per:n;ts ~~ -a very easy escape of the conta;ner at the start of the f;lling, so that there is no undue pressure upon an indiv-;dual flat bag, with resulting damage to its contents, whereas as filling progresses the container is slid less easily. In th;s case however a compensat;on occurs via the elastic cushion formed by the foil packages, and growing larger with increasing stack height.
:~514~
~ ~1421-214 According to one development of the invention, a continuous flexible belt maintained under tensile stress passing over return elements only at the start and end of the conveying path section, which adapts itself between the return elements to the course of the rigid guide means and to the foil package to be transported via the latter is arranged on the outside of the arc of the con-veying path section leading from the horizontal into the vertical.
The transition from the filling of one package container to the next empty package container is effected by creating a gap at the transition from the conveying path with the individually con-veyed foil packages to the conveying pa-th where the imbrication occurs, by faster or slower conveyance. As soon as the gap reaches the package container, it is possible to replace the Eull package container by an empty package container. This may be effected, for example, in that thatend of the transport means extending above the stacking station is retracted in the direc-tion of travel of the belt and then advanced again at the new container. This mode of transition is necessary if the package container can be slid only in the plane of its standing surface.
However, if the package container is raisable and lowerable, then this mode of transition is not necessary. If the lower end of the transport means is nevertheless even then still adjustable in the direction of travel of the belt, then this is only to permit an adaptation to package containers of different height to be per-formed.
The belt should travel through a belt accumulator in order ~25~77 . .
7a 21421-214 to maintain the belt tension. The belt accumulator then com-pensates the different belt lengths in the region of the arcuate guide means which result from the adjustment of the part extend-ing above the stacking station or by different charging heights of the ~2S;~
arcuate conveyor belt section.
Another subject of the ;nvention is a machine for assembling a plura~ity of package containers filled with fo;l packages, ~h;ch consists of a pLurality of appara-tuses of the abovementioned type for transporting foil packages into package containers, arranged mutually parallel. This machine is characterised in that two transporters for different empty package containers lead to each support located beneath the vertica~ conveying path section for the package containers to be filled with foil packages, that transfer elements for the selective transfer of a package container from one or the other transporter ontc, the support are provided, and that from each support a transporter for the filled package con-tainers of the one type leads to a collecting station and a second transporter for filled package containers of the other type to a collecting station common to all the second trar;sporters, wh;lst a distributor is associated with the support for the selective charging of at least one of the transporters with filled packages~
In such a machine, the apparatus for transporting foil packages to the empty package containers can be charged with a d;fferent capacity by the preceding fill-ing and closing machines. The adaptation of the capacityis effected in that some of the foil packages in the highest-capacity line on the apparatus for packing the foil packages are filled into the package containers locked in only sporadically and branched out again, and not into the package conta;ners which are transported to the common collecting station. It is therefore ensured, with the machine according to the invention, that the individual filling and clos;ng machines for the flat bags can be operated at maximum capacity even when ~ t7-~
_ g _ 1 assembling package containers in which foil packages of difFerer,t dimensions and~or wi-th different contents are present.
DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
Brief Description of the Drawing _ _ The invention is explained more fully below with ~ reference to a drawing illustrating an exemplary embodi- ¦
_ment, in which in detail: ¦
Figure 1 shows an apparatus for transporting flex;ble fo;l ¦
packages,constructed as flat bags for example, which are del;vered by a filling machine, not shown, into a package ¦
container in a perspective view and Figure 2 shows a machine for assembling package contai- ¦
ners, wh;ch have been filled with f~at bags by means of apparatuses according to Figure 1, at a common collect-ing station, in a diagrammatic v;ew in plan.
Detalled Descriptibn of the Embbdiment bf the lnvention - ~ .
The apparatus according to Figure 1 comprises three characteristic conveying path sections 2, 3, 4 between the filling and c~osing machine, not shown in Figure 1, for filling the contents into flat bags, and the package container illustrated in the form of a _ -- parallelepipedic folding carton 1 open at the top. The conveying path section 2 is oriented horizontally and consists of a continuous conveyor belt 5, onto which the bags 6 filled by the filling and closing machine are deposited with uniformly distr;buted contents, flat and in a consecutive row. The conveyor belt 5 is adjoined in the second conveying path section 3 by a further ~
conveyor belt 7, likewise horizontal but placed somewhat Z51~7'7 1 lower. This conveyor belt 7 has a slower transport speed than the conveyor belt 5. Due to the different conveying speeds of the two belts 2, 7, the flat bags 6 are ;mbricated at the transition point from the belt 5 onto the belt 7. A gap can be formed in the ;mbricated bag string 8 by a brief commutation to a higher speed.
The transport path section 4 leads from the hori-- zontal ;nto the vert;cal. It comprises a transport belt 9 arranged on the ins;de' of the arc, which ;s guided ;nvar;ably by a guide means, not shown. A second trans-port belt 10, which ;s provided on the outside o~ the arc, ;s passed at the start of the transport path section 4 over a return roller 11 adjustable in height relat;ve to the transport belt 9, and at the end of the transport path sect10n 4 over the stacking station 1~ via a return element 12 not shown in detail, which has a lower height and is adjustable in the direction of travel of the belt.
aetween the return roller 11 and the return element 12 the belt receives its guidance by the belt 9 braced against baffle means and guide means, not shown, in that it is braced against this belt 9, the bags 13 conveyed in the conveying path section 4 being clamped. The belt 10 travels over further return rollers 14 to 17, of which the return roller 17 maintains the belt 10 under tension by means of a spr1ng, not shown~ The roller 17 forms the belt accumulator~
The end of the belt 11 extends into the carton 1.
- ~The carton 1 is influenced in the direction of the arrow 18 by a force, the frictional force of the carton 1 braced against a base, for example, which force however, 'admits a recession (sliding on the base~ of the carton 1 counter to the direction of the force arrow.
The filling of the carton 1 occurs in the follow-ing manner:
:~25~7~
1 The flat bags 6 arriving individually in a conse-cutive row and flat with uniformly distributed contents become imbricated at the transition onto the conveying path 3 ciue to the slower conveying speed, as already explained. The throughput capacity is not reduced by this means, but the transport speed is.
After a specific number of bags 6, which fit into ! a carton ~, for example, the belt 7 is accelerated so that the bag string 8 is separated from the next bag string by form;ng a gap. As soon as the bag string 8 enters the sloping conveying path section 4, the bags are claMped on both sides by the two belts 9, 10. By this means they acquire a definite conveying speed even on the sloping conveying path. It is also ensured by this means that the un;form distr;bution of the contents ;n the bags ;s mainta;ned. ~or is this clamped state of the bags lost when the ;nd;v;dual bag passes out of the reg;on of influence of the belt 9, because ;n the case of the -~ first bag the end wall of the carton 1 assumes the 20 guidance, and then the further imbricated bags. Even after leaving the belt 9, the bags 13 are conveyed a~
a definite conveying speed, because they are subject to the influence of the second conveyor belt 10 until they reach their final position~ Because the second 25 conveyor belt 10 is braced unyieldingly, the bags conveyed into the carton 1 exert a pressure directed counter to the direction 18 of the force, so that the container is slid on its base counter to the force act-ing in the direction of the arrow 18 as the filling progresses. In the simplest case the carton may be depos;ted on a slideway, so that the pressure must be sufficient to set the carton 1 in ~otion. If the pressure is insufficient, or if the pressure would be too great for the contents, a force acting in the direc-tion of movement may be exerted upon the conta;ner add;tionally.
..
1 As soon as the carton 1 has been filled with flat bags, the gap between two consecutive strings 8~ 13 is ut;l;sed in order to withdraw the return element out of the carton 1 and to re;ntroduce it ;nto the next container.
In the case of the mach;ne ;llustrated in Figure

STACKING STATION
BACKGROUND OF THE INVENTION
Field of the Invention The invention relates to a method of transporting flexible foil packages, particul3rly flat bags, ~illed with unstabilised, part;cularly pourable or flowable material, to a package container forming a stacking station, whereby the bags arriving flat in a consecutive row and containing the contents in a distributed manner are transported from a horizontal conveying path section via an arcuate conveylng path section to a f;nal vertical conveying path sect10n extending to the stacking station, upon ~hich the bags are reta;ned clamped on both s;des during the transport.
Discussion of Prior Art In order to acco~modate flexible foil packages, part;cularly flat bags, filled with unstabilised material, part;cularly pourableror flowable material~ as closely as possible in package containers, cases for example, but _ without excessive pressure on the contents, (risk of damage to the contents, soups or fragile chips for example), the material present on one side in the bag after the filling operation and closure is distributed uniformly over the entire bag by agitation, so that the bag transported flat along the first hori~ontal eonvey;ng path section has only a comparatively low he;ght. The flat bags with the contents thus distr;buted, on their further conveying ` ~S~7 1 route, after pass;ng an arcuate sloping convey;ng path~
enter the final almost vert;cal conveying path sect;on, in which they are reta;ned clamped by conveyor belts arranged oppositely. These conveyor belts end above a magazine d;v;ded into compartments, in wh;çh magazine the bags are mutually aligned. As long as the bags are retained cLamped between the conveyor belts on bot~ sides, the unîform distribution of the contents is maintained.
However, after leaving the conveyor belts the bag contents can shift towards the lower edge of the bag again. This shifting is further promoted by the fact that the bags strike the floor of the magazine at unreduced conveying speed, so that the contents also accumulate at the lower edge of the bag for this reason. Due to this one-sided 1S shi~ting of the contents, the compact filling o~ the pack-age container with such bags is not ensured, or the bags are pressed too hard, wh;ch leads to damage to the con- ¦
tents. Furthermore, the bags are shock-stressed again after the transfer of the bags present in the magazine into the package container. Furthermore, the preliminary sorting in a magazine and the transfer into the pack-age container restrict capacity. Lastly, this prelimin-ary storing of the bags is restricted to a specific size of the package container. A particular preliminary magazine has to be made available for each container size.
SUMMARY oF THE INVENTION
....
The underlying object of the invention is to develop a 0ethod of transporting flexible foil packages filled with unstabilised material to a package container~ wh;ch permits a close packing of the foil pàckages without excess;ve pressure upon the contents~ The filling of the package containers should then be possible without maltreat-;ng the contents but w;th a r,igher capacity than hitherto.
` ~;25~77 -3-~
The invention provides a method of filling and transporting containers with filled packages, which comprises the steps of providing flexible filled packages at a plurality of adjacent container filling stations by transporting said packages in a substantially horizontal path, contents of said packages being substantially uniformly distributed, transporting said filled packages further in a downward sloping path for depositing into containers while maintaining substantial distribution un-iformity of said package contents, transporting empty containers of different dimensions for said filled packages to each container filling station from firs~ and second empty container supply stations, filliny the containers with the flexible packages while maintaining substantial distribution uniformity of package cont-ents, transporting said containers filled with packages from the container filling stations to a common collecting station for filling further containers with said containers filled with packages from the adjacent container filling stations.
The invention also provides an apparatus for filllng and transporting containers with filled packages, which comprises a plurality of adjacent container filling stations, said adjacent container filling stations comprising first conveying means for transporting the filled packages in a substantially horizontal path, the contents of said packages being substantially uniformly distributed, second conveying means for receiving filled packages from the first conveying means and for transporting said packages in a downward sloping path for depositing into containers, said second conveying means including means for maintaining substantial distribution uniformity of package contents, first and second ~ z5~ 7~7 -3a ~ ~
empty container supply stations, independent conveying means for transporting containers of different climensions from said fixst and se~ond empty container supply stations to said adjacent container filling stations for filling with said filled packages while maintaining distribution uniformity of package contents, a common collecting station for the filled containers, third con-veyor means for transporting filled containers from said adjacent container filling stations to said common collecting station, and means for filling further containers with said filled con-tainers at said common collecting station.
Preferably the packages are imbricated, and in the container each package is guided on its side facing the package stack by the packages already forming the stack and :is exposed to forces of conveying effect on its side remote from the stack.
Imbrication of the packages has the dual effect that firstly the transport speed is decreased without reducing capacity, and the shock forces at the end of the conveying path are also reduced, and on the other hand the foil packages guide themselves in the package container. Any intermediate sorting in a magazine is therefore eliminated.
Whereas in the known methods the packages are thrown against the container bottom at indefinite speed, whilst they have no front or rear guidance, in the invention they are transported at a precise conveying speed to the bottom of the container, whilst they are braced at both their front and rear :~2~7~
-3b-sides, so that the material distributed uniformly in the pack-age cannot shift to one side. In this manner a close filling of the package container with packages is ensured, without the contents of the packages being thereby exposed to undue compress-ive stresses.
A favourable effect is produced upon the operation of filling the package container with packages if the container is advanced solely by the packages conveyed into the container.
In this case the container should be capable of being slid upon a stationary base. In such a case the weight of the container becomes greater, and the dynamic pressure correspondingly greater, with increasing filling. This is favourab:Le because when only a few packages have been filled into the package container the dynamic pressure should be as weak as possible, because :~2~ 7 1 otherwise there ;s a danger of the indiv;dual container be;ng compressed unduly and the contents might then be damaged. However, when there are a large number of pack-ages in the conta;ner a la'rge elast;c cush;on is present 5 which compensates for any excessive compression of an.
indiv;dual fo;l package.
It occurs frequently in pract;ce that foil pack-ages are f;lled w;th d;fferent contents and/or that fo;l packages of different d;mensions are filled, and that package un;ts ~assortments) are assembled from such fi~led fo;l packages. The assembly is effected from a plural;ty of containers w;th the same dimensions, wh;ch are f;Lled w;th fo;l packages of different contents and/or of differ-ent dimensions from conta;ner to conta;nern However, 15 the parallel operat;on of d;fferent f;lling and clos;ng mach;nes and packag;ng mach;nes for the foil packages w;th ! d;fferent contents and/or d;fferen-t d;mens;ons ;s not ;mmed;ately poss;ble for various reasons. The filling and closing mach;nes generally operate w;th a different 20 capacity. This means that the filling t;me into contain-ers of the same size ;s different for the fo;l packages delivered by the var;ous f;ll;ng and closing mach;nes.
; The output of filled containers may also be dictated by a machine stoppage due to a fault or to a change of foils.
25 Lastly~ a different fill;ng time for the conta;ners may also be d;ctated by the contents or by d;fferent d;men-sions of the packages. In order to prevent an excess;ve _ -over-supply of the containers with packages one or the other type during assembly, the high-output mach;ne may be adapted to the lowest-output machine by throttling. How-ever, this type of adaptation leads to a reductiori in capac;ty in the overall performance of the filling and closing machines and packag;ng machines.
A further claim of the invention therefore is to assemble foil packages with different contents and/or 4~7~7 1 different dimensions ;nto assorted package un;ts and at the same time to operate with maximum capacity on each line of the machines operating in parallel.
According to one development of the invention, i this object is achieved in that package containers are filled with foil packages of different contents and/or different dimensions in a-plurality of parallel lines, whilst empty package containers, which are moved selec-tively from one or the other transport path to the fill~ng station~ are fed to the filling stations via two transport paths each for one type of package container~ and from each f;lling station the filled package containers of the one type are transported via a transport path to a collec-ting station, and the filled package containers of the other type are transported from all the filling stations via further transport paths to a common collecting statlon, where the package containers which contain the foil pack-ages filled with different contents and/or of different dimensions are combined to form package unitsD
In the method according to the invention, the surplus capacity of the strongest line is moderated rela-tive to the weaker lines in that a package container of the one type is locked in repeatedly and intermittently and filled with foil packages at the filling station and transported away again when a sufficient supply of filled package containers of the other type exists at the collec-ting station to assemble package units from them. The -- -filling of package containers of different types with foil packages is poss;ble virtually w;thout interrupting the conveyance of the foil packages to the filling station, because the foil packages pass from the vertical conveying path directly into the containers and do not enter the package containers via an intermediate accumulator, such as a magazine. The method according to the invention ¦ i~
therefore permits lines of different capacity to be 1 coordinated without throttling the capacities of the stronger lines.
A suitable apparatus for perforMing the method, according to the invention, of transport;ng foil packages to a package container consists of a first conveying path section, oriented substantially horizontally, having supporting transport means for ~he foil packages arriving flat in a consecutive row and filled with unstabilised, particularly pourable or flowable, uniformly distributed ma~erial, and of a further conveying path section extend;ng from the hor;zontal arcuately into the ver~;cal to the stacking station and having transport means clamping the foil packages on both sides. According to the invention, this apparatus is characterised in that a second convey-ing path section for imbricating the fo;l packages is arranged between the first and the further conveying path section, and that of the transport means clamp;ng the foil packages, only one transport means extends above the stack to be formed ;n the conta;ner.
Accord;ng to one development of the invention, that part of the transport means extend;ng above thestack to be formed forms an abutment r;g;d in the direc-t;on of the stack axis, w;th which the pillar formed by the wall of the package container slidable on a base and 25 receding with increasing stack height is associated on the oppos;te side of the stack. The we;ght of the pack-age conta;ner increas;ng with progressive f;lling per:n;ts ~~ -a very easy escape of the conta;ner at the start of the f;lling, so that there is no undue pressure upon an indiv-;dual flat bag, with resulting damage to its contents, whereas as filling progresses the container is slid less easily. In th;s case however a compensat;on occurs via the elastic cushion formed by the foil packages, and growing larger with increasing stack height.
:~514~
~ ~1421-214 According to one development of the invention, a continuous flexible belt maintained under tensile stress passing over return elements only at the start and end of the conveying path section, which adapts itself between the return elements to the course of the rigid guide means and to the foil package to be transported via the latter is arranged on the outside of the arc of the con-veying path section leading from the horizontal into the vertical.
The transition from the filling of one package container to the next empty package container is effected by creating a gap at the transition from the conveying path with the individually con-veyed foil packages to the conveying pa-th where the imbrication occurs, by faster or slower conveyance. As soon as the gap reaches the package container, it is possible to replace the Eull package container by an empty package container. This may be effected, for example, in that thatend of the transport means extending above the stacking station is retracted in the direc-tion of travel of the belt and then advanced again at the new container. This mode of transition is necessary if the package container can be slid only in the plane of its standing surface.
However, if the package container is raisable and lowerable, then this mode of transition is not necessary. If the lower end of the transport means is nevertheless even then still adjustable in the direction of travel of the belt, then this is only to permit an adaptation to package containers of different height to be per-formed.
The belt should travel through a belt accumulator in order ~25~77 . .
7a 21421-214 to maintain the belt tension. The belt accumulator then com-pensates the different belt lengths in the region of the arcuate guide means which result from the adjustment of the part extend-ing above the stacking station or by different charging heights of the ~2S;~
arcuate conveyor belt section.
Another subject of the ;nvention is a machine for assembling a plura~ity of package containers filled with fo;l packages, ~h;ch consists of a pLurality of appara-tuses of the abovementioned type for transporting foil packages into package containers, arranged mutually parallel. This machine is characterised in that two transporters for different empty package containers lead to each support located beneath the vertica~ conveying path section for the package containers to be filled with foil packages, that transfer elements for the selective transfer of a package container from one or the other transporter ontc, the support are provided, and that from each support a transporter for the filled package con-tainers of the one type leads to a collecting station and a second transporter for filled package containers of the other type to a collecting station common to all the second trar;sporters, wh;lst a distributor is associated with the support for the selective charging of at least one of the transporters with filled packages~
In such a machine, the apparatus for transporting foil packages to the empty package containers can be charged with a d;fferent capacity by the preceding fill-ing and closing machines. The adaptation of the capacityis effected in that some of the foil packages in the highest-capacity line on the apparatus for packing the foil packages are filled into the package containers locked in only sporadically and branched out again, and not into the package conta;ners which are transported to the common collecting station. It is therefore ensured, with the machine according to the invention, that the individual filling and clos;ng machines for the flat bags can be operated at maximum capacity even when ~ t7-~
_ g _ 1 assembling package containers in which foil packages of difFerer,t dimensions and~or wi-th different contents are present.
DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
Brief Description of the Drawing _ _ The invention is explained more fully below with ~ reference to a drawing illustrating an exemplary embodi- ¦
_ment, in which in detail: ¦
Figure 1 shows an apparatus for transporting flex;ble fo;l ¦
packages,constructed as flat bags for example, which are del;vered by a filling machine, not shown, into a package ¦
container in a perspective view and Figure 2 shows a machine for assembling package contai- ¦
ners, wh;ch have been filled with f~at bags by means of apparatuses according to Figure 1, at a common collect-ing station, in a diagrammatic v;ew in plan.
Detalled Descriptibn of the Embbdiment bf the lnvention - ~ .
The apparatus according to Figure 1 comprises three characteristic conveying path sections 2, 3, 4 between the filling and c~osing machine, not shown in Figure 1, for filling the contents into flat bags, and the package container illustrated in the form of a _ -- parallelepipedic folding carton 1 open at the top. The conveying path section 2 is oriented horizontally and consists of a continuous conveyor belt 5, onto which the bags 6 filled by the filling and closing machine are deposited with uniformly distr;buted contents, flat and in a consecutive row. The conveyor belt 5 is adjoined in the second conveying path section 3 by a further ~
conveyor belt 7, likewise horizontal but placed somewhat Z51~7'7 1 lower. This conveyor belt 7 has a slower transport speed than the conveyor belt 5. Due to the different conveying speeds of the two belts 2, 7, the flat bags 6 are ;mbricated at the transition point from the belt 5 onto the belt 7. A gap can be formed in the ;mbricated bag string 8 by a brief commutation to a higher speed.
The transport path section 4 leads from the hori-- zontal ;nto the vert;cal. It comprises a transport belt 9 arranged on the ins;de' of the arc, which ;s guided ;nvar;ably by a guide means, not shown. A second trans-port belt 10, which ;s provided on the outside o~ the arc, ;s passed at the start of the transport path section 4 over a return roller 11 adjustable in height relat;ve to the transport belt 9, and at the end of the transport path sect10n 4 over the stacking station 1~ via a return element 12 not shown in detail, which has a lower height and is adjustable in the direction of travel of the belt.
aetween the return roller 11 and the return element 12 the belt receives its guidance by the belt 9 braced against baffle means and guide means, not shown, in that it is braced against this belt 9, the bags 13 conveyed in the conveying path section 4 being clamped. The belt 10 travels over further return rollers 14 to 17, of which the return roller 17 maintains the belt 10 under tension by means of a spr1ng, not shown~ The roller 17 forms the belt accumulator~
The end of the belt 11 extends into the carton 1.
- ~The carton 1 is influenced in the direction of the arrow 18 by a force, the frictional force of the carton 1 braced against a base, for example, which force however, 'admits a recession (sliding on the base~ of the carton 1 counter to the direction of the force arrow.
The filling of the carton 1 occurs in the follow-ing manner:
:~25~7~
1 The flat bags 6 arriving individually in a conse-cutive row and flat with uniformly distributed contents become imbricated at the transition onto the conveying path 3 ciue to the slower conveying speed, as already explained. The throughput capacity is not reduced by this means, but the transport speed is.
After a specific number of bags 6, which fit into ! a carton ~, for example, the belt 7 is accelerated so that the bag string 8 is separated from the next bag string by form;ng a gap. As soon as the bag string 8 enters the sloping conveying path section 4, the bags are claMped on both sides by the two belts 9, 10. By this means they acquire a definite conveying speed even on the sloping conveying path. It is also ensured by this means that the un;form distr;bution of the contents ;n the bags ;s mainta;ned. ~or is this clamped state of the bags lost when the ;nd;v;dual bag passes out of the reg;on of influence of the belt 9, because ;n the case of the -~ first bag the end wall of the carton 1 assumes the 20 guidance, and then the further imbricated bags. Even after leaving the belt 9, the bags 13 are conveyed a~
a definite conveying speed, because they are subject to the influence of the second conveyor belt 10 until they reach their final position~ Because the second 25 conveyor belt 10 is braced unyieldingly, the bags conveyed into the carton 1 exert a pressure directed counter to the direction 18 of the force, so that the container is slid on its base counter to the force act-ing in the direction of the arrow 18 as the filling progresses. In the simplest case the carton may be depos;ted on a slideway, so that the pressure must be sufficient to set the carton 1 in ~otion. If the pressure is insufficient, or if the pressure would be too great for the contents, a force acting in the direc-tion of movement may be exerted upon the conta;ner add;tionally.
..
1 As soon as the carton 1 has been filled with flat bags, the gap between two consecutive strings 8~ 13 is ut;l;sed in order to withdraw the return element out of the carton 1 and to re;ntroduce it ;nto the next container.
In the case of the mach;ne ;llustrated in Figure
2, a plural;~y of similar apparatuses 20 of the type descr;bed in conjunction with F;gure I form mutually parallel l;nes~ each together w;th a preced;ng filling and closin~ machine for the filling of contents into flat~
bags and subsequent closing of the flat bags. Different contents and/or differently dimensioned bags are pro-cessed on each l;ne. Because all the l;nes have the same construct;on, the machine is described below solely using the example of one line.
The filling and closing machine 21 deposits the f;lled flat bags with un;formly distr;buted, but d;ffer-ent contents upon a conveyor belt Z2, wh;ch merges ;nto --~ the conveyor belt Z of Figure 1.
Two d;fferent types of package conta;ners (cartons) can be fed to the apparatus 20. A conveyor belt 24 ;s charged w;th cartons 25 of the one type from a supply station 23. The conveyor belt 24 transports the cartons 25 to the s;de of a conveyor belt 26. The carton 25 can be transferred by means of a slider 27 onto the conveyor belt 26, which transports it into the f;ll;ng pos;t;on at the end of the arcuate convey;ng path ~. The carton f;lled with flat bags is conveyed to the s;de by means - slider et cetera - not shown in the drawing, from where it is transferred by means of a further slider 28 onto a transport belt 29 wh;ch trans-ports the filled carton to a collecting station 30.
A belt 32 is charged with empty cartons 33 of the other type from a further supply station 31. From this belt 32, a belt 34 branches off for each apparatus 2û.
1 The carton 33 is transferred by a slider 35 onto this belt 34, which ends at the s;de of the belt 26. From here the carton is slid by means of a further slider 36 onto the belt 26~ which transports it benea~h the end of the arcuate conveying path 4. 9y the selective actua-tion of one or the other slider 27, 36, e;ther the carton of the one type or of the other type can be fed to the apparatus 20.
Instead of the means constructed as sliders for transferring the cartons of one or the other type onto the conveyor belt~ transfer means of a different nature may also be provided, points, for example, which con-nect the conveyor belt 26 w;th the transporter 24 or with the transporter 34. However, it is also possible for the one or other transporter to be arranged in a stra;ght line to the conveyor belt 26. In this case, ~owever, it is necessary to stop the feed of the cartons of the one type when it is requ;red to transfer cartons of the other type onto the belt 26 and to feed them to the apparatus 20.
- The carton 33 passes as a filled carton 37 onto a conveyor belt 3~, wh;ch in conjunct;on with conveyor belts 39, 40 feeds the cartons com;ng from the similar apparatuses, which contain bags with different contentsr to a collecting station 41~ The cartons accumulate at this collecting station 41. A specific number of such cartons, e;ght cartons in the exemplary embodiment, form an assortment and are packed into a larger case which passes from a suppLy station 42 via a conveyor belt 43 beneath a shaft 44, through which the ~artons formin~ an assortment, after being slid laterally by a slider 45, are filled into the case, which then leaves the filling station via a belt 46 as an assortment ~campaign goods~.
S:~4'~7 1 The accumulation of f;lled cartons 37 on the individual conveyor belts 38 - 40 may be monitored by supervising elements, not shown. If it is then ascer-tained that an excessively long accumulation is bu;ld-;ng up on one transport belt, the transfer devices 27, 36 for the cartons of different type may be commuted, namely so that the feed of cartons 31 of the one type is blocked and cartons 25 of the other type are locked into the apparatus 20, which are then fed not onto the conveyor belt 33 but onto the conveyor belt 290 Any excessive capacity ;n one line can be relieved by th;s means. By sporadically locking in a carton 25 into the one or other apparatus 20, all the lines can be operated at maximum capacity; nevertheless no excessive supply of cartons 27 occurs at the common collecting station. It is therefore poss;ble, without interruption, to pack assort-ment goods (campaign goods) and individual goods simult-aneously w;th the mach;ne~
bags and subsequent closing of the flat bags. Different contents and/or differently dimensioned bags are pro-cessed on each l;ne. Because all the l;nes have the same construct;on, the machine is described below solely using the example of one line.
The filling and closing machine 21 deposits the f;lled flat bags with un;formly distr;buted, but d;ffer-ent contents upon a conveyor belt Z2, wh;ch merges ;nto --~ the conveyor belt Z of Figure 1.
Two d;fferent types of package conta;ners (cartons) can be fed to the apparatus 20. A conveyor belt 24 ;s charged w;th cartons 25 of the one type from a supply station 23. The conveyor belt 24 transports the cartons 25 to the s;de of a conveyor belt 26. The carton 25 can be transferred by means of a slider 27 onto the conveyor belt 26, which transports it into the f;ll;ng pos;t;on at the end of the arcuate convey;ng path ~. The carton f;lled with flat bags is conveyed to the s;de by means - slider et cetera - not shown in the drawing, from where it is transferred by means of a further slider 28 onto a transport belt 29 wh;ch trans-ports the filled carton to a collecting station 30.
A belt 32 is charged with empty cartons 33 of the other type from a further supply station 31. From this belt 32, a belt 34 branches off for each apparatus 2û.
1 The carton 33 is transferred by a slider 35 onto this belt 34, which ends at the s;de of the belt 26. From here the carton is slid by means of a further slider 36 onto the belt 26~ which transports it benea~h the end of the arcuate conveying path 4. 9y the selective actua-tion of one or the other slider 27, 36, e;ther the carton of the one type or of the other type can be fed to the apparatus 20.
Instead of the means constructed as sliders for transferring the cartons of one or the other type onto the conveyor belt~ transfer means of a different nature may also be provided, points, for example, which con-nect the conveyor belt 26 w;th the transporter 24 or with the transporter 34. However, it is also possible for the one or other transporter to be arranged in a stra;ght line to the conveyor belt 26. In this case, ~owever, it is necessary to stop the feed of the cartons of the one type when it is requ;red to transfer cartons of the other type onto the belt 26 and to feed them to the apparatus 20.
- The carton 33 passes as a filled carton 37 onto a conveyor belt 3~, wh;ch in conjunct;on with conveyor belts 39, 40 feeds the cartons com;ng from the similar apparatuses, which contain bags with different contentsr to a collecting station 41~ The cartons accumulate at this collecting station 41. A specific number of such cartons, e;ght cartons in the exemplary embodiment, form an assortment and are packed into a larger case which passes from a suppLy station 42 via a conveyor belt 43 beneath a shaft 44, through which the ~artons formin~ an assortment, after being slid laterally by a slider 45, are filled into the case, which then leaves the filling station via a belt 46 as an assortment ~campaign goods~.
S:~4'~7 1 The accumulation of f;lled cartons 37 on the individual conveyor belts 38 - 40 may be monitored by supervising elements, not shown. If it is then ascer-tained that an excessively long accumulation is bu;ld-;ng up on one transport belt, the transfer devices 27, 36 for the cartons of different type may be commuted, namely so that the feed of cartons 31 of the one type is blocked and cartons 25 of the other type are locked into the apparatus 20, which are then fed not onto the conveyor belt 33 but onto the conveyor belt 290 Any excessive capacity ;n one line can be relieved by th;s means. By sporadically locking in a carton 25 into the one or other apparatus 20, all the lines can be operated at maximum capacity; nevertheless no excessive supply of cartons 27 occurs at the common collecting station. It is therefore poss;ble, without interruption, to pack assort-ment goods (campaign goods) and individual goods simult-aneously w;th the mach;ne~
