The device shown is intended and suitable for handling objects. The embodiment shows the promotion of bags 10 and the positioning of the same in a container, namely in a (shipping) carton 11. The bags 10 are made from a foil as outer cover. The contents are particularly sensitive to mechanical Charges. This applies to so-called snacks.

The articles or bags 10 are fed in an upper, horizontal plane, by a belt conveyor designed as a feed conveyor 12. The bag 10th are transported at a distance from each other on an upper run of the feed conveyor 12 and transferred to a (transverse) filling conveyor 13. This promotes the bag 10 down an arcuate trajectory and places the bags 10 in one held, open-top box 11 from. The flat pouches 10 are flat in the transported lying position and turned in the field of Füllförderers 13 in an upright Position. Thus, in this embodiment, the bags 10 will be upright standing stored in the carton 11, to form possibly several rows of bags 14th

The filling conveyor 13 is in construction and function a special feature of the device. Of the Fill conveyor 13 consists of two cooperating elements, namely one segmentally shaped transfer conveyor or deflection conveyor 15 and from a Fixed part, namely a balancing conveyor 16. The deflection conveyor 15 is important for the Handling of sensitive objects, since these or the bag 10 from a horizontal receiving plane during transport along a particular circular arc-shaped Movement path are deflected in a downward position. This section of the conveying movement runs along a particular quarter-circular Train.

The deflection conveyor 15 is a unit of two (endless) conveyors. These are around a main belt 17 and around a support belt 18. The main belt 17 is in the region of Deflection conveyor 15 positioned on the inside of the arcuate transport path. One Conveyor run 19 runs in the region of the deflection over a variety of along a (Circular) arc mounted guide rollers 20. These cause a polygonal course of the main belt 17 and the conveying run 19 in the region of the arcuate path. The Distances of the guide rollers 20 from each other are relatively small to pronounced To avoid kinking of the conveyor run 19.

Accordingly, the support belt 18 is formed, which is in a parallel path to the main belt 17 acts as an external guide in the area of the deflection. The endless support belt 18 is running also over a number of guide rollers 21, the - larger diameter than the guide rollers 20 - are arranged opposite to this, so that a respect of the polygonal course analog contour in the region of the support belt 18 is created.

The main belt 17 is formed as a flat belt. The support belt 18 is in this embodiment from a plurality of juxtaposed single straps, namely in particular of round cords of elastic material. The parallel Round cords together form the support belt 18. Furthermore, the support belt 18 through formed a plurality of individual conveyors, namely one each (from round cords existing) endless conveyor from a guide roller 21 to the adjacent. In which Embodiment (Fig. 5) therefore consists of the support belt 18 of five individual conveyors.

The main belt 17 extends in the region of the movable deflection conveyor 15 and in the Area of the compensation conveyor 16. The latter has a number of guide rollers 22nd on, of which at least two are arranged so that the conveying strand 19 a in Substantial horizontal conveyor section 23 following the feed conveyor 12th forms. This conveying section 23 extends in the plane of the conveying run of the feed conveyor 12 and connects laterally to this by arranging a guide roller 22 immediately adjacent to the feed conveyor 12th

The support belt 18 is adjacent to the conveyor section 23 in the region of the compensation conveyor 16 guided over compensating rollers 24 which are displaceable relative to the compensation conveyor 16 are, namely in slots 25. The (horizontal) reciprocating balancing rollers 24 compensate for length changes in the still to be described Movements of the Umlenkförderers 15.

About a plurality of further guide rollers 26 both of the Umlenkförderers 15 as Also, the balancing conveyor 16 is a Rücklauftrum 27 of the main belt 17 from the equalizing conveyor 16 returned to the deflection conveyor 15. The direction of movement of Belts 17, 18 is determined by the direction of movement of the bag 10 shown. In the area the Umlenkförderers 15 is the Rücklauftrum the Hauptgurts 17 with a large angle of wrap about a arranged on Umlenkförderer 15 drive roller 28 out. This is rotationally driven by a motor 29 (Figure 4). This will be the conveyor drive transferred to the main belt 17.

The arriving on the feed conveyor 12 bags are transversely to the conveying direction of Fördertrum removed and to the immediately laterally adjoining main belt 17th transfer. For this purpose, a transfer conveyor is provided, namely one above the feed conveyor 12 arranged transverse conveyor 30 in the form of an endless belt. The cross conveyor 30 is connected to a deflection roller 31 on the compensating conveyor 16 or on its supporting part stored. The transverse conveyor 30 is pivotable about the deflection roller 31 as a one-armed lever, from an upper inclination in a substantially horizontal conveying position, in which a lower conveying run of the cross conveyor 30 with low pressure at the respective abzufördernden bag 10 is present. By driving the cross conveyor 30 of the bag 10th deported transversely from the feed conveyor 12 and on the horizontal conveyor section 23 filed.

This transports the bag in the deflection between main belt 17 and support belt 18. During transport in this area, the bag 10 is turned so that the bags in the lower exit region of the filling conveyor 13 are positioned upright.

For transferring the bag 10 to the carton 11 or for introduction into this close the Umlenkförderer 15 or main belt 17 on the one hand and support belt 18 on the other further in an upright plane extending conveyor for the bag 10 at. It deals on the one hand to an introduction conveyor 32 in continuation or supplement of the main belt 17 and a counter-conveyor 33 in continuation of the support belt 18th Both conveyors 32, 33 are pivotally mounted as a continuation of the Umlenkförderer 15.

The introduction conveyor 32, which also consists of several straps or round cords, extends into the carton 11, to an area above the Bag 10 of each formed bag row 14. The fed or transported down Bag 10 abuts a conveying run of the introduction conveyor 32, namely until to reach the settling position in the carton 11. The bag 10 on the to the introduction conveyor 32 opposite side detecting counter-conveyor 33 is unpowered and serves to support and guide the bag 10 on the free side. The counter-conveyor 33 ends above the carton 11.

In the formation of the rows of juxtaposed, upright bags 10 within of a carton 11, the bags are successively placed on a bottom of the carton 11 deposed. So that formed sub-rows remain in the upright position is the filling conveyor 13 assigned a support member 34. This is at the introduction conveyor 32 and on attached to a support frame of the same and independently movable up and down. The Support member 34 consists in this example of an upright support wall 35, by means of Mounting bracket 36 is attached to an upright guide 37. By the dimension of the Support bracket 36 is the support wall 35 each spaced from the conveyor plane the introduction conveyor 32. This creates a space between the conveying strand of the Insertion conveyor 32 on the one hand and the support wall 35 on the other. In this room enters the bag 10 during the downward movement and finally through the support wall 35 until it rests against an adjacent bag of the partially formed row of bags 14 held (Fig. 5, Fig. 6 and Fig. 8). The support wall 35 extends into the area the bag row 14.

The introduction conveyor 32 is assigned a further auxiliary member for securing a desired relative position of the bag 10 in the box 11. It is a Justierorgan, namely an upright pressure plate 38. This is in the range of partially formed bag row 14 effective by moving the bag 10 by transverse movement the bag row 14 are detected and compressed within the bag row 14. Fig. 10 shows the position of the pressure plate 38 in the alignment or alignment of Bag 10 of an (upper) bag row 14. Also, the pressure plate 38 is along an upright Guide 39, adjacent to the guide 37, movable in the upright direction.

The guiding and adjusting organs for the bags 10, namely the supporting member 34 with retaining wall 35 and the pressure plate 38 are on opposite sides of the upright Insertion conveyor 32 arranged. At the upright Fördertrum 40 are the Bag 10 in the downward transport on. By far this is the Supporting wall 35. The pressure plate 38 is opposite to the Rückführstrum opposite 41 of the insertion conveyor 32 is arranged. The guides 37 and 39 are at one Mounted bracket 42 for the insertion conveyor 32.

Insertion conveyor 32 and counter-conveyor 33 are aligned in a parallel position, regardless of movements of Umlenkförderers 15. In the present Embodiment is the introduction conveyor 32 via a differential gear, via a parallel rod 43 with the Umlenkförderer 15, namely with a Carrying device of the same connected, such that during pivoting movements of the Umlenkförderers 15 of the introduction conveyor 32 is always held in an upright position. The parallel rod 43 is for this purpose via lever 44, 45 on the one hand with an upper Rotary or deflection axis of the insertion conveyor 32 and on the other hand with a rotation axis the Umlenkförderers 15 connected.

A special feature are the possibilities of movement of the filling conveyor 13 and the deflection conveyor 15. The latter consists of a support arranged in an upright plane, which is formed in the present case as a support plate 46. On both sides of the Support plate 46 are organs of Umlenkförderers 15 arranged. Located on one side the projecting from one side of the support plate 46, so projecting guide rollers 20, 21 and 26. Further, the drive roller 28 is for the main belt 17 on this side of the support plate. Opposite is the engine 29 for the Drive the Hauptgurts or the drive roller 28. In the lower part of the segment-like formed support plate 46 is a pivot bearing 47 for the support plate 46 with a Motor 48. The deflection conveyor 15 is pivotable about the pivot bearing 47 by the motor 48. This pivotal movement of the Umlenkförderers 15 causes a change the height position in the region of introduction conveyor 32 and counter-conveyor 33, namely in particular when storing the bags in several rows one above the other (Fig. 9, Fig. 10). In the different relative positions of the deflection conveyor 15 (FIG on the one hand, Fig. 8 on the other hand) remain inlet of the bag with horizontal orientation of the Conveying section 23 and position in the region of the exit side, namely the insertion conveyor 32, 33 unchanged.

As a further feature of the device, the filling conveyor 13 is a total of horizontal Plane movable, simplified represented by X and Y axes in Fig. 1. To this Purpose of the filling conveyor 13 is mounted on a total of a portal-like structure. This consists of a supporting structure in the direction of the X-axis, namely two parallel Beams 49, 50. For this transverse extends below the carrier 49, 50 a Cross member 51. The cross member 51 is movably connected to the carriers 49, 50, is so in the longitudinal direction movable (X-axis). The cross member is for this purpose upright supporting struts 52 connected to the carriers 49, 50, with an in or on the carriers 49, 50 movable drive. Advantageously, the carriers 49, 50 designed as a (square) profile carrier, each with a running within the carrier Carriage. This is movable by a toothed belt. In the example shown is a motor 53 for driving both carriages in the carriers 49, 50 via a transverse Wave provided. The support struts 52 are each connected to a carriage.

The cross member 51 is preferably formed as the carrier 49, 50, so with a movable slide. At this a downward bracket 54 is attached, is formed angle-shaped. In the area of a horizontal leg is the deflection conveyor 15 attached to the pivot bearing 47 and the motor 48 on this support arm 54. The support arm 54 and thus the Umlenkförderer 15 is (rectilinear) on the cross member 51 movable. A motor 55 serves to drive a carriage within the cross member 51st

In this end position will be the bag 10 is detected by the cross conveyor 30 and on the main belt 17 in the region of the conveying section 23 transmitted. The bags 10 then run in the deflection of the Umlenkförderers 15 and are at the exit area, formed by the introduction conveyor 32 and the counter-conveyor 33, passed. The last conveyor section within of the carton 11 can take place in free fall, as the counter-conveyor 33 above the carton ends. The introduction conveyor 32 can be used to guide the bag 10 as Saugbandförderer be formed. The bags 10 are on the bottom of the carton in upright Position deposed, wherein by moving the Umlenkförderers 15 along the Cross member 51, the relevant bag row 14 is gradually filled. For education an adjacent further row of bags 14, the deflection conveyor 15 together with the compensation conveyor 16 in the longitudinal direction of the carrier 49, 50 method, ie in the X direction. For this purpose, the compensation conveyor 16 and a support plate 57 thereof connected to the conveyor in the X direction, with the cross member 51, so that during a movement of this cross member 51 along the carrier 49, 50 of the filling conveyor 13th total procedure is. This movement is also followed by the transverse conveyor 30 including stop 56. The movement can take place in several stages, namely according to the Number of juxtaposed rows of bags 14.

The height adjustment of the filling conveyor 13 and the Umlenkförderers 15 carried by the already described pivoting movement about the pivot bearing 47. Fig. 7 shows the position for the introduction of bags 10 for a lower layer. Fig. 9 is the changed position in the formation of a second or upper layer of bag rows 14. In the pivoting movements of Umlenkförderers 15 of the balancing conveyor 16 remains in the same relative position. The same applies to movements in the Y direction.

The peculiarity of the device lies in the simple transmission of movements in upright (pivotal movements) and linear movements in horizontal Level in two directions.
