Description
~osno~
~ackground of the Invention The present invention relates to an arrangement for converting a called-for multi-row stream of containers into a single-row stream of containers that is to be withdrawn.
An arrangement of this general type is known from European patent application 0 252 461. With this known arrangement, a called-for multi-row stream of bottles is converted in two stages on the intermediate conveyor mechanism as well as on the withdrawal mechanism into the single-row stream of bottles that is to be withdrawn. In particular, this is effected in such a w~y that at the outlet region of the intermediate conveyor mechanism a two-row stream of bottles is still present that is then finally converted in the withdrawal mechanism into the single-row stream of bottles. For separation of the called-for stream of bottles, the intermediate conveyor mechanism adjoins the feed mechanism via a transition means that is formed by at least one transfer plate. Furthermore, formed in a conversion zone of the intermediate conveyor mechanism is a lane means that is laterally delimited by guide means, i.e. by guide railings that are disposed there. The track or conveying width of the lane means, when viewed in a conveying 2~80~
direction, decreases in a funnel-like manner and symmetrically relative to a horizontal central axis that extends in the conveying direction. The conversion zone of the intermediate conveyor mechanism is embodied as an acceleration stretch for the bottles, i.e. at this location it comprises a plurality of conveyor belts that in part are also narrow conveyor belts and form groups or conveying sections having conveyor belts that follow one another in the conveying direction. The conveyor belts can be driven in a staged or progressive manner with varying speeds in such a way that a conveying speed results that increases in the conveying direction. At that location where conversion of the two-row stream of bottles into the single-row stream of bottles is effected, the known arrangement is again provided with a transition means formed by at least one transfer plate.
It is an object of the present invention to provide an arrangement that, as an alternative to the state of the art, makes it possible, at a high efficiency or output, to convert in only a single stage, with no pressure or force, a called-for multi-row stream of containers into a single-row stream of containers that is to be withdrawn.
2080~55 Brief Description of the Drawings This object, and other objects and advantages of the present invention, will appear more clearly from the following specification in conjunction with the accompanying schematic drawing which is a simplified plan view of one exemplary embodiment of the inventive arrangement for converting a called-for multi-row stream of bottles into a single-row stream of bottles that is to be withdrawn.
Summary of the Invention Pursuant to the present invention, the arrangement for converting a multi-row stream of containers into a single-row stream of containers comprises a plurality of continuously rotating conveyor belts having upper runs that form support surfaces for the containers, including first conveyor belts that form a multi-row feed mechanism having first guide railings, and, following the feed mechanism in the conveying direction at first transition means, second conveyor belts, some of which form an intermediate conveyor mechanism that, to separate and convert the multi-row stream of containers, forms a first lane means for the containers, with the first lane means being delimited by side guide means and, in a first region of the intermediate conveyor mechanism that 208~5~
follows the feed mechanism in the conveying direction having a constant conveying width that corresponds to a width of the multi-row stream of containers, and in a second region of the intermediate conveyor mechanism that follows the first region thereof narrowing in width in the direction of the conveying direction and symmetrically relative to a central axis of the first lane means that extends in the conveying direction, the first lane means narrowing to a conveying width that corresponds to a width of the single-row stream of containers, with a withdrawal mechanism adjoining an outlet region of the intermediate conveyor mechanism on a downstream side thereof, the withdrawal mechanism including at least one of the second conveyor belts to form a second lane means for the containers, with the second lane means being delimited by second side guide railings and having a conveying width that corresponds to the width of the single-row stream of containers, the second lane means of the withdrawal mechanism directly adjoining the outlet region of the intermediate conveyor mechanism symmetrically relative to the central axis, whereby the second conveyor belts are disposed symmetrically relative to the central axis and form 2080~5 a plurality of conveying sections that are symmetrical relative to the central axis and in a direction perpendicular to the conveying direction are adjacent one another, with each of the conveying sections, in the direction of the conveying direction, comprising ones of the second conveyor belts that follow one another at respective second transition means, whereby in the direction of the conveying direction, the second conveyor belts have a progressive varying speed with at least three speed changes such that in a given one of the conveying sections, with respect to successive second conveyor belts thereof as viewed in the conveying direction, that second conveyor belt that is closer to the withdrawal mechanism has a higher speed than does the preceding second conveyor belt, whereby the second conveyor be:Lts at least partially also have a progressive varying speed in a direction perpendicuLar to the conveying direction such that with respect to two adjacent ones of the second conveyor belts as viewed in a direction perpendicular to the conveying direction, that second conveyor belt that is more remote from the central axis has the slower speed, and whereby the first region of the intermediate conveyor mechanism 2~8~V5~
has a length as viewed in the conveying direction that is at least equal to the length of the second region of the intermediate conveyor mechanism, and is preferably greater than this second region.
With the inventive arrangement, the loosening or separating and also the conversion of the multi-row stream of containers is effected exclusively in the intermediate conveyor mechanism. In particular, the separating of the called-for s-tream of containers taXes place especially in the first region of the intermediate conveyor mechanism, whereby for this purpose this first region has an adequately long length as viewed in the conveying direction, and in this first region the lane means formed between the guide means or railings has a constant width that corresponds to the multi-row stream of containers. In the following second region of the intermediate conveyor means, where the lane means narrows in a funnel or wedge-shaped manner, there is then effected the combining together of the separated stream of containers into the single-row stream of containers. In both regions of the intermediate conveyor mechanism the lane means is symmetrical to the central axis.
With respect to configuration, arrangement, as well as grouping of the second conveyor belts and the 20800~5 conveying sections formed therefrom, the intermediate conveyor mechanism is symmetrical to the central axis in the region of the lane means, the connection or transition of the intermediate conveyor mechanism to the withdrawal mechanism, as well as lane means of the withdrawal mechanism provided immediately following the intermediate conveyor mechanism and having a track or conveying width that corresponds to the single-row stream of containers. This is also applicable at least with respect to the speed gradients or stages in the conveying direction. Due to the speed gradients or stages in a direction perpendicular to the conveying direction, which stages are preferably also symmetrical to the central axis, there results an optimum acceleration and separation of the container stream and hence an optimum joining together of the containers into the single-row stream of containers without force or pressure.
In order to optimize the separation of the s-tream of containers in the first region of the intermediate conveyor mechanism, that portion of this region that directly adjoins the feed mechanism is embodied as a dosing band or region that is provided with at least one disturbance or build-up sensor that controls the feed mechanism, 20800~
which is then operated as a storage means or band.
Further specific features of the present invention will be described in detail subsequently.
Description of Preferred Embodiments Referring now to the drawing in detail, illustrated is an arran~ement for converting a called-for multi-row stream of a plurality of bottles 1 into a single-row stream of bottles that is to be withdrawn. The arrangement essentially comprises a feed mechanism 2, an intermediate conveyor mechanism 3, and a withdrawal mechanism 4.
The feed mechanism 2, which serves for supplying the multi-row stream of bottles and in the illustrated embodiment at the same time functions as a storage means, is essentially formed from a plurality of continuous or closed conveyor belts 5 that are driven in an endlessly rotating manner by a non-illustrated regulatable drive means. The feed mechanism 2 is also formed from two guide railings 6 that delimit the track or conveying width of the feed mechanism 2. In the illustrated embodiment, the arrow A indicates the conveying direction of the feed mechanism 2, with this conveying direction A also being the conveying direction of the intermediate conveyor mechanism 3 and the withdrawal mechanism 4.
~08005~
The intermediate conveyor mechanism 3, where the actual conversion of the multi-row stream of bottles into the single-row stream of bottles takes place, essentially comprises a plurality of conveyor belts 7 that are driven in an endlessly rotating manner via non-i.llustrated drive means.
In part, the conveyor belts 7 follow one another in the conveying direction A, and in part the conveyor belts 7 are also disposed next to one another as viewed in a direction perpendicular to the conveying direction A. The intermediate conveyor mechanism 3 is also comprised of two side guide railings 8, each of which follows one of the guide railings 6 when viewed in the conveying direction A. In the inlet region 3' of the intermediate conveyor mechanism 3, the guide railings 8 initially extend parallel to one another as well as parallel to a horizontal central axis M that extends in the conveying direction A. In the region 3', the guide railings 8 thus define a lane for the bottles 1, with this lane having a constant width that corresponds to the conveying width of the feed mechanism 2. In the region 3" that follows the first region 3', the guide railings 8 continue to extend symmetrically relative to the central axis M, but they also extend at an angle to 20~0~
this central axis, i.e. to the conveying direction A, and in particular in such a way that the width of the lane formed between the two guide railings 8 continuously decreases in the region 3". In this way, a conversion zone is obtained that narrows in a wedge-shaped manner and is symmetrical to the central axis M; in this conversion zone, the track or conveying width of the intermediate conveyor mechanism 3, at its outlet region remote from the feed mechanism 2, ultimately corresponds to the single-row stream of bottles.
The inlet region of the intermediate conveyor mechanism 3, which faces the feed mechanism 2, adjoins the latter via a transition means or zone 9, formed from at least one slide plate, in such a way that the tracks or rows of the feed mechanism 2 and the intermediate conveyor mechanism 3 correspond with one another. The transition zone 9, i.e. the at least one slide plate, forms a transfer edge 9'.
The narrow conveyor belts 7, which are narrower than the conveyor belts 5, form a number of conveying sections, and in particular:
a central conveying section Fl, which is provided direct~y on the central axis M and is coaxial therewith, the central conveying 20~0~5 section F1 being formed by a plurality of conveyor belts 7 that follow one another in the direction of the central axis M, i.e. in the conveying direction A; and further lateral conveying sections F2-F6, which are respectively provided in pairs and symmetrically relative to the central axis M, and when viewed in a direction perpendicular to the conveying direction A are disposed adjacent to either the central conveying section F1 or to one another.
Thus, provided on both sides of the central conveying section F1 is a respective conveying section F2, provided to the side of each conveying section F2 is a respective conveying section F3, etc. In the illustrated embodiment, all of the conveying sections F2-F6 also comprise a plurality of conveyor belts 7 that follow one another in the conveying direction A.
The upper lengths or runs of both the conveyor belts 5 and of the conveyor belts 7 respectively form a horizontal or essentially horizontal support or transport surface, the shape or configuration of which is adapted to the track or conveying width of the region 3", which narrows in a wedge-shaped manner in the conveying direction A. In 2~800~
particular, either the length of the conveyor belts 7 is appropriately selected, at least in the region 3", or the number of the conveyor belts 7 that form the individual conveying sections F1-F6 decreasa from the central or inner conveying section F1 to the more outwardly disposed conveying sections F2-F6.
In the region where the conveyor belts 7 of the conveying sections Fl-F6 are disposed ad;acent to one another, transition means or zones 10 that are respectively formed by plates are provided.
These transition means or zones 10, i~e. where the directions of the conveyor belts 7 are reversed, are respectively offset in a comb-like manner in the conveying direction A. In other words, each transition zone 10 or direction reversal of a conveyor belt 7 of a conveying section is, when viewed in a direction perpendicular to the conveying direction A, disposed adjacent to the continuous upper run of a conveyor belt 7 of an adjacent conveying section and is bridged or overlapped by this adjacent conveyor belt 7. The respective downstream ends of the conveyor belts 7, as viewed in the conveying direction A, are driven.
The corresponding axes are designated by the reference numeral 11.
20800~
In the illustrated embodiment, the last conveyor belts 7 that form the outlet region of the intermediate conveyor mechanism 3 continue to be disposed on both sides of the central axis M at this outlet region and are at the same time also the conveyor belts of the withdrawal mechanism 4 and, at their downstream end, as viewed in the conveying direction A, are driven by a drive means.
The corresponding axis is designated by the reference numeral 11'.
To join the multi-row, called-for stream of bottles together into a single-row stream of bottles that is to be withdrawn without pressure or force, the intermediate conveyor mechanism 3 is operated as a multi-stage acceleration section; in other words, the drive means for the individual conveyor belts are such that in each conveying section F1-F6 each successive conveyor belt 7 as viewed in the conveying direction A has a greater conveying speed than does the preceding conveyor belt 7 when viewed in the conveying direction A.
Furthermore, in the illustrated embodiment, at least in the region 3`', but also in a portion of the region 3' that precedes the region 3" relative to the conveying direction A, the speed of the drive means for the conveyor belts 7 is stepped or 2~0~5~
staged such that when viewed in a direction perpendicular to the conveying dire~tion A, the conveying speed of adjacent conveyor belts 7 decreases from the inner conveying section Fl toward the outer conveying sections F60 In this connection, it is to be understood that the conveying speed of the two conveyor belts 7 that form the outlet region of the intermediate conveyor mechanism 3 is at the same time the conveying speed of the withdrawal mechanism ~. Due to the fact that the conveying speed of the conveyor belts 7 is staged not only in the conveying direction A but also in a direction perpendicular to the conveying direction, and due to the great length of the region 3', an optimum loosening or separating of the supplied multi-row stream of bottles is already achieved in the region 3'. Subsequently, in the region 3", accompanied by a further separation, an optimum joining together of the bottles 1 is achieved, so that on the whole a joining together of the multi-row stream of bottles without force or pressure into a single-row stream of bottles results even at high outputs.
No transition zone formed by a transfer plate is required where the w-thdrawal mechanism 4 follows the intermediate conveyor mechanism 3 or in - ~4 -208~0~
the region of the withdrawal mechanism 4. It is to be understood that the conveying speed of the withdrawal mechanism is greater than the conveying speed of the feed mechanism, and in particular by a factor that corresponds to the number of tracks or rows of the multi-row stream of bottles.
The intermediate conveyor mechanism 3 is symmetrical relative to the central axis M with respect to the arrangement and grouping of the conveyor belts 7 and the conveying sections F1-F6, as well as with respect to the staged and varying conveying speeds of the conveyor belts 7.
In the illustrated embodiment, the portion of the region 3' of the intermediate conveyor mechanism 3 that immediately follows the feed mechanism 2 is provided with a disturbance or build-up sensor 12 that controls the feed mechanism 2. In other words, this portion of the region 3', i.e. the conveyor belts 7 of the intermediate conveyor mechanism 3 that are provided at that location, at the same time serve as a control or regulating buffer for the feed mechanism 2.
The withdrawal mechanism 4 is disposed symmetrically relative to the central axis M and already at the outlet region of the intermediate conveyor mechanism 3 forms a single lane for the 2~80~5~
bottles 1 with a track or conveying width that corresponds to the single-row stream of bottles.
The withdrawal mechanism 4 is essentially formed from the aforementioned conveyor belts 7 as well as from two guide railings 13, each of which adjoins one of the guide railings 8 and which extend parallel to one another as wall as to the central axis M, from which they are respectively equally spaced. The distance between the two guide railings 13 naturally corresponds to the track or conveying width of the single-row stream of bottles.
Disposed at the side of the outlet of the withdrawal mechanism 4, which is disposed remote from the intermediate conveyor mechanism 3, is a conveyor means 14 that is formed from guide railings 15 and a conveyor belt 16 that corresponds to the conveyor belts 5. By appropriate configuration of the guide railings 15, the bottles 1 of the single-row stream of bottles are shunted or transferred sideways onto the conveyor means 14.
In the illustrated embodiment, the guide railings 8 form an angle of about 15 to 30 with the central axis in the region 3".
The present invention has been described with the aid of specific embodiments. However it is to 20~0~5 be understood that changes and modifications are possible without thereby deviating from the basic concept of the invention. Thus, it is clear that the use of the arrangement is not limited to the conversion of a multi-row stream of bottles into a single-row stream of bottles; rather, the inventive arrangement can be used for any multi-row stream of containers, which can be formed from bottles, cans, or other containers, and which can then be optimally converted into a single-row stream of containers.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawing, but also encompasses any modifications within the scope of the appended claims.

a central conveying section Fl, which is provided direct~y on the central axis M and is coaxial therewith, the central conveying 20~0~5 section F1 being formed by a plurality of conveyor belts 7 that follow one another in the direction of the central axis M, i.e. in the conveying direction A; and further lateral conveying sections F2-F6, which are respectively provided in pairs and symmetrically relative to the central axis M, and when viewed in a direction perpendicular to the conveying direction A are disposed adjacent to either the central conveying section F1 or to one another.
Thus, provided on both sides of the central conveying section F1 is a respective conveying section F2, provided to the side of each conveying section F2 is a respective conveying section F3, etc. In the illustrated embodiment, all of the conveying sections F2-F6 also comprise a plurality of conveyor belts 7 that follow one another in the conveying direction A.
The upper lengths or runs of both the conveyor belts 5 and of the conveyor belts 7 respectively form a horizontal or essentially horizontal support or transport surface, the shape or configuration of which is adapted to the track or conveying width of the region 3", which narrows in a wedge-shaped manner in the conveying direction A. In 2~800~
particular, either the length of the conveyor belts 7 is appropriately selected, at least in the region 3", or the number of the conveyor belts 7 that form the individual conveying sections F1-F6 decreasa from the central or inner conveying section F1 to the more outwardly disposed conveying sections F2-F6.
In the region where the conveyor belts 7 of the conveying sections Fl-F6 are disposed ad;acent to one another, transition means or zones 10 that are respectively formed by plates are provided.
These transition means or zones 10, i~e. where the directions of the conveyor belts 7 are reversed, are respectively offset in a comb-like manner in the conveying direction A. In other words, each transition zone 10 or direction reversal of a conveyor belt 7 of a conveying section is, when viewed in a direction perpendicular to the conveying direction A, disposed adjacent to the continuous upper run of a conveyor belt 7 of an adjacent conveying section and is bridged or overlapped by this adjacent conveyor belt 7. The respective downstream ends of the conveyor belts 7, as viewed in the conveying direction A, are driven.
The corresponding axes are designated by the reference numeral 11.
20800~
In the illustrated embodiment, the last conveyor belts 7 that form the outlet region of the intermediate conveyor mechanism 3 continue to be disposed on both sides of the central axis M at this outlet region and are at the same time also the conveyor belts of the withdrawal mechanism 4 and, at their downstream end, as viewed in the conveying direction A, are driven by a drive means.
The corresponding axis is designated by the reference numeral 11'.
To join the multi-row, called-for stream of bottles together into a single-row stream of bottles that is to be withdrawn without pressure or force, the intermediate conveyor mechanism 3 is operated as a multi-stage acceleration section; in other words, the drive means for the individual conveyor belts are such that in each conveying section F1-F6 each successive conveyor belt 7 as viewed in the conveying direction A has a greater conveying speed than does the preceding conveyor belt 7 when viewed in the conveying direction A.
Furthermore, in the illustrated embodiment, at least in the region 3`', but also in a portion of the region 3' that precedes the region 3" relative to the conveying direction A, the speed of the drive means for the conveyor belts 7 is stepped or 2~0~5~
staged such that when viewed in a direction perpendicular to the conveying dire~tion A, the conveying speed of adjacent conveyor belts 7 decreases from the inner conveying section Fl toward the outer conveying sections F60 In this connection, it is to be understood that the conveying speed of the two conveyor belts 7 that form the outlet region of the intermediate conveyor mechanism 3 is at the same time the conveying speed of the withdrawal mechanism ~. Due to the fact that the conveying speed of the conveyor belts 7 is staged not only in the conveying direction A but also in a direction perpendicular to the conveying direction, and due to the great length of the region 3', an optimum loosening or separating of the supplied multi-row stream of bottles is already achieved in the region 3'. Subsequently, in the region 3", accompanied by a further separation, an optimum joining together of the bottles 1 is achieved, so that on the whole a joining together of the multi-row stream of bottles without force or pressure into a single-row stream of bottles results even at high outputs.
No transition zone formed by a transfer plate is required where the w-thdrawal mechanism 4 follows the intermediate conveyor mechanism 3 or in - ~4 -208~0~
the region of the withdrawal mechanism 4. It is to be understood that the conveying speed of the withdrawal mechanism is greater than the conveying speed of the feed mechanism, and in particular by a factor that corresponds to the number of tracks or rows of the multi-row stream of bottles.
The intermediate conveyor mechanism 3 is symmetrical relative to the central axis M with respect to the arrangement and grouping of the conveyor belts 7 and the conveying sections F1-F6, as well as with respect to the staged and varying conveying speeds of the conveyor belts 7.
In the illustrated embodiment, the portion of the region 3' of the intermediate conveyor mechanism 3 that immediately follows the feed mechanism 2 is provided with a disturbance or build-up sensor 12 that controls the feed mechanism 2. In other words, this portion of the region 3', i.e. the conveyor belts 7 of the intermediate conveyor mechanism 3 that are provided at that location, at the same time serve as a control or regulating buffer for the feed mechanism 2.
The withdrawal mechanism 4 is disposed symmetrically relative to the central axis M and already at the outlet region of the intermediate conveyor mechanism 3 forms a single lane for the 2~80~5~
bottles 1 with a track or conveying width that corresponds to the single-row stream of bottles.
The withdrawal mechanism 4 is essentially formed from the aforementioned conveyor belts 7 as well as from two guide railings 13, each of which adjoins one of the guide railings 8 and which extend parallel to one another as wall as to the central axis M, from which they are respectively equally spaced. The distance between the two guide railings 13 naturally corresponds to the track or conveying width of the single-row stream of bottles.
Disposed at the side of the outlet of the withdrawal mechanism 4, which is disposed remote from the intermediate conveyor mechanism 3, is a conveyor means 14 that is formed from guide railings 15 and a conveyor belt 16 that corresponds to the conveyor belts 5. By appropriate configuration of the guide railings 15, the bottles 1 of the single-row stream of bottles are shunted or transferred sideways onto the conveyor means 14.
In the illustrated embodiment, the guide railings 8 form an angle of about 15 to 30 with the central axis in the region 3".
The present invention has been described with the aid of specific embodiments. However it is to 20~0~5 be understood that changes and modifications are possible without thereby deviating from the basic concept of the invention. Thus, it is clear that the use of the arrangement is not limited to the conversion of a multi-row stream of bottles into a single-row stream of bottles; rather, the inventive arrangement can be used for any multi-row stream of containers, which can be formed from bottles, cans, or other containers, and which can then be optimally converted into a single-row stream of containers.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawing, but also encompasses any modifications within the scope of the appended claims.
