(2) The FIGURE shows a schematic illustration of: a top view of an apparatus according to the invention for handling articles.

DETAILED DESCRIPTION OF THE INVENTION

(3) An apparatus 01 for handling articles 02, as illustrated completely or in parts in the FIGURE comprises:

(4) a first conveyor 03 for the supply of articles 02,

(5) a second conveyor 04 for the supply of outer packagings 05,

(6) a third conveyor 06 for the discharge of outer packagings 05 with articles 02 placed therein, termed for short, filled outer packagings 07, and

(7) a placing surface 08 arranged between the second conveyor 04 and the third conveyor 06, as well as

(8) a device 09, illustrated by a dashed line, for the transfer indicated by arrows 91 of supplied outer packagings 05 from the second conveyor 04 to the placing surface 08,

(9) a device 10, illustrated by a dashed line, for the transferring indicated by arrows 101 of articles 02 from the first conveyor 03 into outer packagings 05 having been transferred onto the placing surface 08, and

(10) a device 11, illustrated by a dashed line, for the transfer indicated by arrows 111 of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06.

(11) The device 10 for the transferring indicated by arrows 101 of articles 02 first seizes the articles 02 staged by means of the first conveyor 03, then transfers the seized articles 02 from the first conveyor 03 to the placing surface 08 and, in the process, places the articles 02 having been seized and having been transferred from the first conveyor 03 to the placing surface 08 by it into the outer packagings 05 having been transferred onto the placing surface 08.

(12) The apparatus 01 allows carrying out a method for handling articles 02, which method provides that articles 02 are placed into outer packagings 05 staged on a placing surface 08, which articles 02 are supplied in one or in a plurality of article flows of articles 02 lined up one after the other uninterruptedly and/or with gaps between them and/or grouped, which outer packagings 05 themselves in turn are supplied independently of the articles 02 in a transport direction indicated by arrows 41 and are transferred, as indicated by arrows 91, onto the placing surface 08 individually or groupwise transversely to the transport direction indicated by arrows 41 and, after the articles 02 have been placed therein, they are transferred, as indicated by arrows 111, from there in turn individually or groupwise transversely to the transport direction indicated by arrows 41now provided with articles 02 placed thereinin order to be subsequently discharged in the direction of the transport direction indicated by arrows 41 or opposite to it in parallel to the transport direction indicated by arrows 41 independently of the supply indicated by arrows 31 of articles 02, independently of the supply indicated by arrows 41 of outer packagings 05, and independently of the placing indicated by arrows 41 of articles 02 into the outer packagings 05.

(13) Both the apparatus 01 and the method can be further developed as explained in the following.

(14) The device 09 for the transfer indicated by arrows 91 of outer packagings 05 from the second conveyor 04 onto the placing surface 08 can comprise the device 11 for the transfer indicated by arrows 111 of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06 or one or more parts of the device 11 for the transfer indicated by arrows 111 of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06.

(15) Alternatively, the device 09 for the transfer indicated by arrows 91 of outer packagings 05 from the second conveyor 04 onto the placing surface 08 can be completely or partly comprised by the device 11 for the transfer indicated by arrows 111 of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06.

(16) The device 09 for transferring supplied outer packagings 05 from the second conveyor 04 to the placing surface 08 and the device 11 for transferring filled outer packaging items 07 from the placing surface 08 onto the third conveyor 06 thus each in themselves or together form at least one transfer device 12 that is formed and drivable independently of the device 10 for transferring articles 02 from the first conveyor 03 into outer packagings 05 having been transferred onto the placing surface 08.

(17) The placing surface 08 in connection with the at least one transfer device 12 that is independent of the device 10 for transferring articles 02 from the first conveyor 03 into outer packagings 05 having been transferred onto the placing surface 08 results in an increase in performance with regard to the pacing that is achievable based on an apparatus without placing surface 08. The higher pacing is achieved, because, by means of the placing surface 08 in connection with the at least one transfer device 12 that is independent of the device 10 for transferring articles 02, articles 02 supplied by means of the first conveyor 03 can be seized by the device 10 for transferring articles 02 in a first cycle, and the device 10 for transferring articles 02 can begin with transferring the seized articles 02 by starting a movement of the seized articles 02 from the first conveyor 03 to the placing surface 08 while outer packagings 05 that are still empty are simultaneously transferred, for instance, by pushing off or over, from the second conveyor 04 to the placing surface 08 and outer packagings 07 are transferred by pushing off or over from the placing surface 08 onto the third conveyor 06, and in a second cycle new, empty outer packagings 05 can be supplied by means of the second conveyor 04 and outer packagings 07 can simultaneously be discharged from the third conveyor 06, while the transferring of the articles 02 having been seized in the first cycle is simultaneously completed by placing articles 02 by means of the device 10 for transferring articles 02 into the outer packagings 05 staged on the placing surface 08.

(18) In this context, the transferring of the articles 02 seized in the first cycle is concluded by placing the articles 02 having been seized by the device 10 for transferring articles 02 into the empty outer packagings 05 having been transferred by pushing off or over onto the placing surface 08 in the first cycle, and by a return of the device 10 for transferring articles 02 from the placing surface 08 to the first conveyor 03 at least being started, in order to again seize and, in a repetition of the first cycle, transfer articles 02 supplied from the first conveyor 03.

(19) The transfer indicated by arrows 91 from the second conveyor 04 to the placing surface 08 can be carried out by pushing over supplied outer packagings 05.

(20) The transferring as indicated by arrows 101 can be carried out by gripping the articles 02, pushing the gripped articles over the edge of the first conveyor 03 or by slightly lifting the gripped articles from the first conveyor 03 as well as lowering them into the outer packagings 05 staged on the placing surface 08.

(21) The transfer indicated by arrows 111 from the placing surface 08 to the third conveyor 06 can be carried out by pushing over outer packagings 07.

(22) Preferentially, at least the second conveyor 04 and the third conveyor 06 are arranged in parallel to each other along the placing surface 08, at least in the area of their portions 32, 42, 62 abutting on the placing surface 08 or, in other words, the second conveyor 04 and the third conveyor 06 run in parallel to each other at least in the area of their portions 32, 42, 62 abutting on the placing surface 08.

(23) In addition, the first conveyor 03 can run in parallel to the second conveyor 04 and in parallel to the third conveyor 06.

(24) In the arrangement in parallel to each other, the transport directions indicated by arrows 31, 41, 61 of the conveyors 03, 04, 06 run in parallel to each other at least in the area 82 located between the arrows 81 of their portions 32, 42, 62 abutting on the placing surface 08, or, as the case may be, of their portions 32, 42, 62 overlapping each other in the area of the placing surface 08. This applies to transport directions of all conveyors 03, 04, 06 running in the same direction as well as to transport directions of at least two conveyors 03, 04, 06 running in opposite directions.

(25) The parallelly arranged portions 32, 42, 62 of the conveyors 03, 04, 06 can overlap one another by a distance indicated by the double arrow 83 of the length of at least two, preferably at least three outer packagings 05 staged on the placing surface 08.

(26) In this way, two or more outer packagings 05 can be simultaneously transferred from the second conveyor 04 onto the placing surface 08 and two or more outer packagings 07 can be simultaneously transferred from the placing surface 08 to the third conveyor 06, and likewise articles 02 can be simultaneously placed into the plurality of outer packagings 05 that are thus staged on the placing surface 08. The pacing can thus be further increased.

(27) The direction of the transfer of outer packagings 05, termed for short transfer direction, indicated by arrows 91, and being carried out by the device 09 for transferring empty outer packagings 05 from the second conveyor 04 to the placing surface 08, runs, in a horizontal direction, preferably transversely, preferentially in orthogonal to the transport direction indicated by arrows 41 of the second conveyor 04.

(28) The direction of the transfer of outer packagings 07, which direction is termed for short transfer direction, is indicated by arrows 111, and is being carried out by the device 11 for transferring filled outer packagings 07, from the placing surface 08 to the third conveyor 06, runs, in a horizontal direction, preferably transversely, preferentially in orthogonal to the transport direction indicated by the arrow 61 of the third conveyor 06.

(29) In the transfer from the second conveyor 04 to the placing surface 08 and in the transfer from the placing surface 08 to the third conveyor 06, the transfer direction indicated by arrows 91 and by arrows 111 of the device or devices 09 for transferring preferably both the empty outer packagings 05 and the filled outer packagings 07, thus preferentially runs, in a horizontal direction, preferably transversely, preferentially in orthogonal to the transport directions indicated by arrows 41 and 61 of both the second conveyor 04 and the third conveyor 06.

(30) By the transversal and preferably orthogonal horizontal transfer direction indicated by arrows 91 and by arrows 111 in relation to the transport directions indicated by arrows 41 and 61 of the second conveyor 04 and the third conveyor 06, one or more empty outer packagings 05 as well as one or more filled outer packagings 07, can be respectively simultaneously transferred from the second conveyor 04 to the placing surface 08 as well as from the placing surface 08 to the third conveyor 06, whereby articles 02 can be simultaneously placed into a plurality of outer packagings 05 that have been put down on the placing surface 08. The pacing can thus be significantly increased.

(31) For instance, the device 09 for transferring outer packagings 05 from the second conveyor 04 onto the placing surface 08 and/or the device 11 for transferring filled outer packagings 07, from the placing surface 08 onto the third conveyor 06 can comprise at least one slider.

(32) The second conveyor 04 and the third conveyor 06 as well as the placing surface 08 are preferentially located on a common, first level.

(33) The first conveyor 03 is preferably located on a higher, second level.

(34) A vertical stroke of the device 10 for transferring articles 02, which vertical stroke is necessary for placing articles 02 into outer packagings 05, can thus be reduced to the essential, whereby the pacing can be further increased.

(35) The second level can be located above the first level by at least the height of an outer packaging 05, which is initially open and to be closed after placing the articles 02 therein, as the case may be.

(36) In the instance of flaps for closing that protrude to the top from an outer packaging 05 designed as a closeable cardboard packaging, the second level is preferentially located accordingly higher, by the height of the flaps protruding above the first level, than in the instance of the outer packagings 05 being closed, for instance, with a separately provided lid.

(37) The closing of the filled outer packagings 07, can be carried out while still on the placing surface 08, for instance, together with or subsequent to placing the articles 02 into the outer packagings 05, or in a separate treatment step, for instance, subsequent to or in the further course of the third conveyor 06 of the apparatus 01 for handling articles 02.

(38) For instance, the filled outer packagings 07, can be closed with lids in the further course of the third conveyor 06.

(39) Prior to placing the articles 02 into outer packagings 05 having been transferred onto the placing surface 08, compartments 13, also termed so-called baskets, can be inserted into the outer packagings 05, which compartments 13 assign fixed positions to the articles 02 within the outer packagings 05 and thus protect them, during the further transport of the filled outer packagings 07 until the articles 02 are withdrawn and consumed, from colliding with each other and rubbing against each other, which otherwise would lead to a negative impression of the quality by scuffing, for instance, of information applied onto the articles 02 in the form of labels, for example, and/or by the articles 02 damaging each other.

(40) The compartments 13 can already have been or be inserted into the outer packagings 05 prior to the transfer of the outer packagings 05 to the placing surface 08, or the compartments 13 can be inserted into the outer packagings 05 prior to or together with or after the articles 02 being placed into the outer packagings 05.

(41) The compartments 13 can be staged, for instance, by a separate device 14, which can simultaneously erect the compartments 13, for instance.

(42) The subsequent introduction of compartments 13, in particular with lightweight articles 02 that are shiftable with little effort within the outer packagings 05, has the advantage of a simplified placing of the articles 02 in the outer packagings 05, along with a reduced controlling effort for the device 10 for transferring the articles 02, because articles 02 with a shape, for example, tapering conically or in a similar manner toward their oppositely located contact surfaces, such as beverage bottles with a bottle neck widening at least sectionwise from the top downward, can be horizontally shifted within the outer packagings 05 by the compartments 13 when these are inserted.

(43) The compartments 13 can be introduced into the outer packagings 05, for instance, while still on the second conveyor 04, or they can be introduced into the outer packagings 05, for instance, already together with or subsequent to erecting these, or they can already be integrated into an according cardboard packaging, wherein the compartments 13 unfold within the outer packaging 05 with the cardboard packaging being erected.

(44) In connection with introducing compartments 13 prior to or after placing articles 02 into the outer packagings 05, a separate introduction surface can alternatively be provided between the second conveyor 04 and the placing surface 08 in the instance of the introduction of compartments 13 prior to placing the articles 02, or between the placing surface 08 and the third conveyor 06 in the instance of the introduction of compartments 13 after placing the articles 02.

(45) In this context, an additional device can be provided for the transfer of outer packagings 05 provided with compartments 13 from the introduction surface to the placing surface 08 or from the placing surface 08 to the introduction surface, which additional device can also be part of a transfer device 12 or be comprised by it.

(46) In the further course of the third conveyor 06 of the apparatus 01 for handling articles 02, a stacking station can be provided, where, for instance, filled outer packagings 07, taking the form of closed outer packagings 05 with articles 02 placed therein, are grouped into stack layers and stacked onto a stack, which is then discharged in order to make room for stacking up a new stack after reaching a specified stacking height according to a specified number of stack layers stacked on top of each other at the stacking station.

(47) The articles 02 supplied by means of the first conveyor 03 are preferentially already sorted into article groups 21 to be respectively placed into an outer packaging 05. The articles 02 supplied by means of the first conveyor 03 can abut on each other or they can be supplied lined up one after the other with gaps between them. The articles 02 supplied by means of the first conveyor 03 can be supplied in one row or in a plurality of rows running in parallel. For this purpose, the articles 02 can be transferred to the first conveyor 03 via a suitable infeed, and be guided in one or in a plurality of lanes oriented in parallel to each other after the transfer to the first conveyor 03.

(48) The articles 02 supplied by means of the first conveyor 03 accordingly form a single- or multiple-row article flow of articles 02 lined up one after the other uninterruptedly and/or with gaps between them.

(49) Before the articles 02 are subsequently placed into the outer packagings 05 by means of the apparatus 01 for handling articles 02, the said articles 02 can have been previously treated along an infeed to the first conveyor 03, for instance, by producing a container and/or cleaning an outer and/or inner surface and/or cooling and/or filling and/or closing, in order to name only a few examples of treating articles 02 without claim to completeness of the list, and/or the articles 02 can have been previously handled along an infeed to the first conveyor 03, for instance, by separating a number of articles 02 from one or more article flows of articles 02 being transported immediately following each other and/or grouping a number of articles 02 into article groups 21 and/or compiling and assembling a number of articles 02 into bundles, in order to name only a few examples of handling articles 02 without claim to completeness.

(50) The conveyors 03, 04, 06 preferentially comprise at least one horizontal conveyor device, such as, for instance, a belt conveyor and/or a roller conveyor.

(51) The outer packagings 05 can preferentially be cardboard packagings, for instance, in the form of cardboard boxes with or without compartments 13 arranged or arrangeable therein for separating and/or keeping apart individual articles 02 from each other.

(52) It is obvious that the invention can be realized by an apparatus 01 for handling articles 02 with:

(53) a first conveyor 03 supplying articles 02 in a first transport direction indicated by arrows 31,

(54) a second conveyor 04 supplying outer packagings 05 in a second transport direction indicated by arrows 41 and preferentially directed in parallel to and running in the same direction as or opposite to the first transport direction indicated by arrows 31,

(55) a third conveyor 06 discharging filled outer packagings 07, in a third transport direction indicated by an arrow 61 and preferentially directed in parallel to and running in the same direction as or opposite to the first transport direction indicated by arrows 31 and to the second transport direction indicated by arrows 41,
a placing surface 08 arranged between the second conveyor 04 and the third conveyor 06,
a device 09 for the transfer indicated by arrows 91 of supplied outer packagings 05 from the second conveyor 04 to the placing surface 08,
a device 10 for the transferring indicated by arrows 101 of articles 02 from the first conveyor 03 into outer packagings 05 having been transferred onto the placing surface 08, and
a device 11 for the transfer indicated by arrows 111 of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06,
wherein the device 09 for the transfer of supplied outer packagings 05 from the second conveyor 04 to the placing surface 08 and the device 11 for the transfer of filled outer packagings 07, from the placing surface 08 onto the third conveyor 06 can be combined in one common transfer device 12.

(56) The invention has been described with reference to a preferred embodiment. Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the invention and that such changes and modifications can be made without departing from the spirit of the invention. It is, therefore, intended that the appended claims cover all such equivalent variations as fall within the true spirit and scope of the invention.
