The auxiliary component is smaller than 50 percentage of the main component.

Description

The invention relates to a device for merging a first flat carton having at least two second flat cartons, wherein a first transport device is provided for the first carton and wherein the at least two second cartons brought by means of a separate second transport device to the first carton and applied to this become.

Such devices are known and serve to interconnect two cartons, i. to provide a cardboard box with a carton. The outer carton, for example, serves to protect or support the actual carton packaging on the way to its destination. There, the carton is removed from the actual carton packaging. However, these known devices are also used to provide boxes with one or more reinforcements.

In these known devices, the cardboard is guided in the transport direction and the cardboard or cardboard parts to be adhered are brought laterally, ie from the left and / or right. These cartons or cardboard parts have a transport direction which is perpendicular to the aforementioned transport direction. In order to enable an exact, ie precise position joining, the transport of the carton must be stopped during the joining process so that the other carton or the carton parts can be precisely aligned and laid on top. Then the cardboard is transported on and discharged. This method is not only slow and can not drive high transport speeds, but it also high drive performance is required because the drive units must be permanently accelerated and decelerated. Therefore, the drive units and other drive components are subject to high wear.

From the US 2002/0077236 A1 a device for merging carton blanks is known in which the carton blanks are sometimes bent very strong. As a result, damage to the carton blanks can not be excluded.

The invention is therefore based on the object to provide a device of the type mentioned above, with which at high transport speed, a carton can be merged or equipped with several cartons or cardboard parts, the carton blanks are treated gently.

This object is achieved with a device having the features of claim 1.

In the apparatus according to the invention, the second cartons to be applied, which are cartons or cardboard parts, are not brought transversely to the first carton, but essentially in the same transport direction, so that relatively high transport speeds can be driven since, on the one hand, there are no abrupt changes of direction. on the other hand, the cartons need not be stopped during the joining process and then accelerated again.

According to the invention it is provided that the transport path for the second cartons one parallel to the second Cartons seen, having an S-shaped trajectory, which ends substantially tangentially on the transport path of the first cartons or passes into these.

By the S-shaped trajectory of the second cartons abrupt deflections are avoided, so that especially thick second boxes are not kinked or jammed or pre-punched cutouts in the second cartons are not broken. In addition, a gentle support of the second cartons is achieved by the tangential connection of the S-shaped trajectory to the transport path of the first cartons, wherein the first and second cartons are already aligned parallel to each other immediately before the system and have the same transport speed in the same direction.

The major component of the second transport direction is superimposed on a minor component, with the minor component pointing in the direction of the first carton on which the second cartons are to be placed. If, for example, a second carton is brought from above onto the first carton, then the second carton is transported on the one hand in the same direction as the first carton, but on the other hand also approaches the first carton. This approach corresponds to the secondary component of the second transport direction, the main component pointing parallel to the first transport direction of the first carton. During the approaching process, the second carton can already be aligned so that it has the exact position at the time of application and the first carton can be removed with the second carton laid on it without delay and subsequent acceleration.

In a development of the invention, it is provided that the secondary component of the second transport direction is both perpendicular to the main component and perpendicular to the plane of the first carton and smaller than 50% of the main component.

As already mentioned, the minor component points in the direction of approach and perpendicular to the plane of the first carton. The second boxes can be brought from above or below to the first box.

For storing the first and second boxes, first and second shafts are provided, from which the boxes are individually removable. In this case, the second shafts for the second cartons are arranged side by side and in particular above the first shaft for the first carton. The second wells for the second cartons may in one embodiment be formed by a single well divided by one or more partitions.

When not in use, the second shafts for the second cartons can be displaced from the filling area of the first shaft of the first carton, in particular laterally displaced so that the access to the first shaft is free from the rear and from the top and thereby the filling, which manually or automatically can be facilitated. In this case, all shafts both in the transport direction, i. from behind, and / or perpendicular to the plane of the carton, i. from above, to be filled. In particular, whole carton stacks can be filled into these shafts, the individual cartons each being removed from the bottom of the stack.

The cartons are transported via belts, in particular via cam belts, which are toothed on the inside and Therefore, slip-free and accurate position can be driven. In this case, each cam belt can be driven with its own drive, so that in this way the positions of the individual second cartons can be determined exactly. Thus, for example, a second carton can lead or lag over the other second carton, so that the cartons can be placed at different positions, ie offset relative to one another, on the first carton.

Preferably, the cams of the cam belt can attack either front of the cartons or rear. This automatically aligns the boxes, in which case when the cams on the back of the boxes attack, they can also be transported. If the cams engage the front of the boxes, additional transport belts are required to transport the boxes.

Preferably, elements for the lateral position alignment of the cartons are provided. These elements can be in the form of guide or guide plates or guide rollers and they can be arranged on the supports for the conveyor belts or they can be mounted on separate holders, so that they can be individually adapted to the width of the boxes.

According to a preferred embodiment, it is provided that a manhole module having the shafts and a glue and joining module having a glue station are provided and the two modules can be moved apart in the transport direction of the cartons. In this way, the device according to the invention can be pushed apart in the event of repair or maintenance, so that maintenance personnel can easily step between the two modules and carry out repair work. As a result, adjustments can be carried out in a simple manner, jammed cardboard boxes removed or, for example, clogged glue nozzles are cleaned. An exact positioning of the individual modules relative to one another takes place in that at least one of the modules is arranged on rails and can be moved on them.

Further advantages, features and details of the invention will become apparent from the subclaims and the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. In this case, the features shown in the drawing and mentioned in the claims and in the description may each be essential to the invention individually or in any combination.

In the FIG. 1 are designated by the reference numeral 10, a first carton and by the reference numerals 12 and 14, two second cartons. The two second boxes 12 and 14 abut each other at 16, can overlap there and can be glued or clamped together there. The two boxes 12 and 14 may also have a small distance from one another. The transport direction of the cartons 10 to 14 is designated by 18.

In the FIG. 2 the two second boxes 12 and 14 are placed on the first box and glued together with this, for example, via glue spots 20 together.

In the FIG. 3 an embodiment of the device according to the invention is shown in a perspective view and designated by the reference numeral 22. In this case, negligible components are omitted. The device 22 consists essentially of a pit module 24 and a glue and joining module 26. The glue and joining module 26 is stationarily mounted on supports 28, whereas the pit module 24 on rails 30 relative to the glue and joining module 26 and in the transport direction 18 is movable.

The shaft module 24 has a first shaft 32 into which a stack of first cartons 10 can be inserted. Above this first shaft 32 are two second shafts 34 and 36, in which the two second boxes 12 and 14 can be inserted, which may have different cross-sections and thicknesses. The two second shafts 34 and 36 are formed in a preferred embodiment of a single shaft, which is divided with partitions 38 in the two shafts 34 and 36 or in yet other shafts. By adjusting the dividers 38 and the outer walls 40, the wells 34 and 36 can be set exactly to the width of the second cartons 12 and 14 and the position of these second cartons 12 and 14 can be adjusted transversely with respect to the first carton. For this purpose, the partitions 38 and the walls 40 are fastened via fastening arms 42 to a cross-beam 44.

When these second shafts 34 and 36 are not in use, the dividing walls 38 and the walls 40 can be displaced laterally outwards from the filling area of the first shaft 32. This also applies to the second transport devices 46 and 48, which are located below the second shafts 34 and 36. Also below the first shaft 32 is a first transport device 50.

In the transport direction 18 to the manhole module 24 is then the glue and joining module 26, in which the first carton 10 and / or the two second cartons 12 and 14 glued, merged and interconnected and transported away.

To transport the boxes 10 to 14 serve cam belt 52, as shown in the FIG. 4 are shown. In this case, cams 54 engage the rear in the transport direction 18 edges of the boxes 10 to 14 and align in this way the boxes. In this case, the cam belt 52 are offset from one another such that the cam 54 also abut against the rear edges of the boxes 10 to 14, if they have no rectangular shape. This is made possible in a simple manner in that each cam belt 52 has its own drive and the individual cam belts 52 are adjusted via the position of the drives. The transport speeds of the cam belt 52 are the same.

In the FIG. 5 Clearly the transition 56 from the manhole module 24 to the glue and joining module 26 can be seen. In the glue and joining module 26, the cardboard 10 to 14 are also taken over by cam belt 52 and transport direction 18 transported.

The FIG. 6 , in which a side view of the device 22 is shown, shows an S-shaped transport path 58, with which the second cartons 12 and 14 are moved in both the transport direction 18 and in the direction of the first carton 10. In this case, the arrow 60 denotes a main component, in which the boxes 10 to 14 are transported. The arrow 62 designates a secondary component, in the direction of which the second cartons 12 and 14 are transported and thereby approximated to the first carton 10, so that the second cartons 12 and 14 can be placed on the first carton 10.

By means of the S-shaped transport path 58, this secondary component 62 is delayed to zero when the boxes 10 to 14 are stacked.

It is essential that all boxes 10 to 14 are permanently transported in the direction of the main component 60 and thus in the transport direction 18. None of the boxes 10 to 14 is in a to the drawing level of FIG. 6 orthogonal direction, ie transported transversely to the main component 60 or transport direction 18. The transport path 58 terminates (left) substantially tangentially above the first carton 10, so that the second cartons 12 and 14 can be placed parallel to the surface on this. Furthermore, it is advantageous that the conveyor belts located below the shafts 32, and are each drivable jointly for a shaft by means of a separate drive, so that the boxes 10, 12 and 14 are pulled off the shafts 32, 34 and 36 independently of one another can be.

In the FIG. 7 the two modules 24 and 26 are pushed apart, so that in the maintenance case, eg for adjustments, when a carton is jammed or if, for example, a glue nozzle is clogged, an operator between the two modules 24 and 26 occur and can perform the maintenance and repair work. Subsequently, the modules 24 and 26 again, as in FIG. 6 shown, collapsed.

In the FIG. 8 is in enlarged scale the section VIII according to FIG. 6 represented and the transition 56 shown. The first cartons 10 are transported toward the main component 60. The second cartons 12 and 14 are transported toward both the main component 60 and the minor component 62. she reach the transport path 58 and are S-shaped directed in the direction of the plane of the first 10 cartons. In this case, constantly engage cam 54 on the backs of the boxes 10 to 14, transport them and align them permanently. The lateral alignment via baffles 64, which in FIG. 5 are shown.
