Description

The invention is in the field of materials handling and relates to a method and a device according to the preambles of the corresponding independent claims. Method and apparatus are used to convert a stream of at least limited bendable, flat objects, the objects are aligned prior to conversion substantially transversely and after the conversion parallel to the conveying direction or wherein the objects aligned parallel before conversion and after the conversion transversely to the conveying direction are and wherein the flat objects, when they are aligned parallel to the conveying direction, one behind the other, that is not overlapping each other, are promoted. The flat objects are in particular rectangular or square; they are, for example, printed products or stacked groups of parts of multi-page printed products.

Since with the same delivery rate for a stream in which the flat objects mentioned are arranged parallel to the conveying direction and successively significantly higher conveying speeds are necessary, as for a stream in which the objects are arranged transversely to the conveying direction, it is a concern of the conveyor technology, whenever possible, to convey the flat objects with an orientation transverse to the conveying direction or parallel to the conveying direction and overlapping each other, this concern is getting more and more weight with increasing flow rates. As it is especially for continuously promoted items To be performed processing steps is often necessary to align the subsidized objects one behind the other and parallel to the conveying direction, power transformations, as defined above, necessary if the promotion should be limited in parallel and consecutively to a necessary minimum.

The mentioned current transformations are realized according to the prior art, for example by a deflection of the objects by an angle of 90 °, which is carried out simultaneously with a transfer from a feed conveyor to a removal conveyor. In order to keep the device moderate expenditure for such conversions in a tolerable mass and still be able to move the objects guided during the transfer and diversion, usually feeders and removal conveyors are used for the said power conversions, of which at least one is operated alternately, or it will when using two continuously operated conveyors at least partially unguided movement accepted in the transfer.

In the publication US 1760030 a transfer of adhesive bound books from a binding machine is described in a drying device, wherein the books are conveyed in the binding machine behind and parallel to a first conveying direction and in the drying device transversely to a second conveying direction and wherein the two conveying directions are substantially horizontal and an angle of 90 ° and the output of the binding machine is above the entrance of the dryer. For the deflection, the books are released from the holding means of the binding machine to fall unguided into the conveying compartments of the drying machine.

The document US-A-5,324,025 discloses a method according to the preamble of claim 1, wherein the cross conveyor is driven in steps.

The document WO-A-03/078080 discloses a method for converting a stream of flat objects from a cross conveyor into a parallel conveyor or a parallel conveyor into a transverse conveyor using two continuously operated conveyors, wherein the parallel conveyor is pivotable and controllable so that it during the transfer of the objects with in essentially the same direction and speed as the cross conveyor pivots.

It is now the object of the invention to provide a method and a device that can be used for the above-mentioned power transformations, wherein methods and device should allow to carry out the power conversion with continuously operating funding, but always keep the objects held during the power conversion and still get along with simple means.

This object is achieved by the method and the device as defined in the claims.

According to the invention for the promotion, in which the objects are arranged transversely to the conveying direction (transverse conveying), a continuously operated transverse conveyor is used with a transverse conveying direction, for example, a plurality of rotating conveyor compartments, which are arranged substantially transverse to the transverse conveying direction and in which the flat For example, objects are held by gravity. Such a transverse conveyor has a plurality of outlets or entrances which move in the transverse conveying direction and at the transverse conveying speed. The cross conveyor are associated with auxiliary conveying means, which are arranged for example in the conveyor compartments and with the aid of which a conveyed by the cross conveyor object is transversely displaceable to the transverse conveying direction.

For the promotion in which the Gegensätnde are arranged parallel to the conveying direction and behind each other (parallel delivery), a continuously driven parallel conveyor is used with a parallel conveying direction and a parallel conveying speed, for example, a pair of conveyor belts, between which the objects are conveyed trapped. Such a parallel conveyor has an input and output which is substantially stationary.

Cross conveyor and parallel conveying means are operated continuously and with the same conveying cycle (same conveying capacity), the transverse conveying speed and parallel conveying speed being coordinated with one another in such a way that the objects conveyed in parallel have a predetermined distance from one another. Depending on the direction of the current conversion (transverse conveyance to parallel conveyance or parallel conveyance to transverse conveyance), the transverse conveying means is the conveying or conveying conveyor or the parallel conveyor is the conveying away or conveying conveyor. In each conveyor cycle, there is a moment in which an output or input of the Querfödermittels is aligned with the input and output of the longitudinal conveyor.

Transverse conveying means, auxiliary conveying means and parallel conveying means are arranged such that the conveying direction of the auxiliary conveying means is aligned parallel to the parallel conveying direction and that the transverse conveying direction forms an angle of, for example, 90 ° with the parallel conveying direction. During the power conversion, the auxiliary conveyor accelerates the objects in the parallel conveying direction from standstill to the parallel conveying speed or delays them accordingly.

Between transverse conveying means and parallel conveying means is provided an alignment means which is aligned with the entrance of the conveying conveyor and whose function is to successively grab and move objects during the power conversion such that their leading edge is directed precisely against the entrance of the conveying means and it bends transversely to its direction of travel in a trailing region between the exit of the delivery means and the registration means. For a power conversion from transverse conveying to parallel conveying, a stationary alignment means aligned with the stationary input of the parallel conveyor is to be provided. For a power conversion from parallel feed to transverse feed, a single alignment means can also be provided, which accompanies one feed of the transverse conveying means in the transverse conveying direction per conveying cycle and moved back to its starting point (alternating alignment means). It can also be provided a plurality of corresponding circumferential alignment means or it can be provided at each entrance to the transverse conveyor an alignment means.

The alignment means according to the invention consists of a pair of counter-rotating driven alignment rollers which have a constant maximum radius in a part of its circumference and in the remaining part of the circumference a smaller radius and their axes of rotation are aligned parallel to each other and perpendicular to the parallel conveying direction. The driving speed of the aligning rollers is such that their surface speed in the area of the constant radius is substantially equal to the parallel conveying speed and that the areas of the constant radius of the two rollers are in synchronism with the conveying stroke of the transverse conveyor and longitudinal conveyor facing each other and in this configuration during one Hold holding an object positioned between the rollers and can move with parallel conveying speed.

The distances between the input or output of the parallel conveyor and the aligning means and between a momentarily involved in the power conversion Ausoder input of the cross conveyor and the alignment are as small as possible and in any case greater than that each object during the conversion always simultaneously from either the feed conveyor and the Alignment or held by the alignment and the Wegförderer. In this way it is ensured that the objects are safely guided during the entire power conversion, even if the conveying and the conveying means are operated continuously and in different directions. The abovementioned distances are also to be adapted to the flexibility or bendability of the objects and to their extent in the longitudinal conveying direction.

FIGS. 1 to 4 show an exemplary embodiment of the inventive method on a very schematically illustrated exemplary embodiment of the inventive device. The illustrated method is a power conversion from cross-feed to parallel feed. The device shown has as feeder a cross conveyor 1 with a transverse conveying direction FQ. The transverse conveyor 1 has a series of conveying compartments 11 with lateral outlets 13 oriented transversely to the transverse conveying direction FQ. As a removal conveyor is a parallel conveyor 2 with a parallel conveying direction FP, for example, a stationary conveyor belt pair with a stationary input 21 or a simple conveyor belt is provided. Between cross conveyor 1 and parallel conveyor 2 is a stationary, on the Input 21 of the parallel conveyor 2 aligned alignment means 3, which has two alignment rollers 31 and 32 of the form already described above. The compartments 11 of the cross conveyor 1 are associated with auxiliary conveying means, not shown, for example, slide whose effect on the objects in the compartments 11 are shown with arrows 12.

The FIGS. 1 to 4 show the device, for example, in a plan view, such that transverse conveying direction FQ and parallel conveying direction FP lie in a horizontal plane and enclose an angle of 90 °. With such an orientation of the device according to the invention, the conveying compartments 11 of the transverse conveyor can be open at the top and on both sides, in particular for the handling of heavier objects, which are held in such a position of the device by gravity in the compartments. The auxiliary conveyor may consist of one slide per compartment.

However, said alignment of the device is not a prerequisite for the inventive method. The FIGS. 1 to 4 For example, they can also be regarded as side views, with the transverse conveying direction FQ then running vertically and the parallel conveying direction being horizontal. In this case, the directed in the figure against the viewer sides of the conveyor compartments 11 may optionally be equipped with means that prevent leakage of the objects. It is also not a prerequisite for the inventive method that the angle between the transverse conveying direction FQ and parallel conveying direction FP is a right angle. Should this angle be other than a right angle, it must be ensured by appropriate arrangement of the compartments 11 relative to the transverse conveying direction, that nevertheless the conveying direction of the auxiliary conveying means is aligned parallel to the parallel conveying direction.

The FIGS. 1 to 4 represent the inventive power conversion is essentially based on the transfer of the article 5, which is conveyed in the conveying compartment 11.1 of the cross conveyor and fed via the alignment means 3 to the parallel conveyor.

In FIG. 1 The conveying compartment 11.1 approaches the entrance 21 of the parallel conveyor 2 with the object 5, and an edge 5.1 of the object 5 leading in the parallel conveying direction FP has left the conveying compartment 11.1 and already moves into the action area of the alignment means 3, driven by the auxiliary conveying means. The accelerating effect of the auxiliary conveying means is visible at the positions of the objects in the compartments 11.2 to 11.4 following the compartment 11.1.

FIG. 2 shows the moment in which the output 13 of the compartment 11.1 is aligned exactly with the input 21 of the parallel conveyor. At this moment, the object has a speed corresponding to the parallel conveying speed and starts the action of the alignment means on the object 5 by being gripped between the leading ends of the roller areas of constant maximum radius. The leading edge 5.1 of the article 5 is aligned from this moment by the alignment means 3 exactly on the entrance 21 of the parallel conveyor 2 and guided into this. The trailing portion of the article 5 is bent by the relative movement between the compartment 11.1 and alignment 3 after this moment.

FIG. 3 shows the article 5 at a moment in which its leading edge 5.1 is already held in the parallel conveyor 2, in which the effect of the alignment means 3 has already ceased on the object 5 and in which the object 5 but always is still bent and although between the entrance 21 of the parallel conveyor 2 and the exit 13 of the compartment 11.1.

FIG. 4 finally shows how the object 5 disappears in the entrance 21 of the parallel conveyor 2 and how another, in the following compartment 11.2 zugeförderter object is guided by the auxiliary conveying means in the region of the alignment means 3.

From the FIGS. 1 to 4 is simply seen that it is readily possible to provide with a cross conveyor 1 two or more than two parallel conveyor with objects. In this case, the inputs of the parallel conveyor 2 are arranged to be aligned parallel to each other, for example, at a distance corresponding to a whole multiple of the departmental distances. The auxiliary conveying means are then to be controlled equally in groups of compartments 11, each compartment of such a group being associated with one of the parallel conveyors.

FIGS. 5 to 8 show in the same device and in the same way as in the FIGS. 1 to 4 , a power conversion from a parallel promotion to a cross-promotion. The conveying directions FQ and FP and thus also the conveying direction of the auxiliary conveying means (arrows 12), not shown, are thus compared with FIG FIGS. 1 to 4 in the opposite direction and the alignment rollers 31 and 32 rotate in the reverse direction. The auxiliary conveying means are configured, for example, as grippers displaceable in the compartments 11, which grasp the objects on their inner edge (see also FIG Fig. 12 ). Furthermore, the alignment means 3 is on the input 13 'of the conveyor compartment 11.1, through which the currently to be handed over object is to take, aligned, that is, at least during its effect on the article 5 with the compartment 11.1 mitgefördert in transverse conveying direction.

FIG. 5 shows the exit of the leading edge 5.1 of the article 5 from the output 21 'of the parallel conveyor 2 and FIG. 6 the beginning of the action of the alignment means 3 on the leading portion of the article 5 in the moment in which the input 13 'of the cross conveyor 1 and thus also the alignment means 3 is aligned with the output 21' of the parallel conveyor 2. FIG. 7 shows the between the output 21 'of the parallel conveyor 2 and input 13' of the compartment 11.1 bent object 5 after the effect of the alignment means 3 has already stopped. FIG. 8 shows still the last part of the retraction of the article 5 in the compartment 11.1 and the emergence of a follower article from the output 21 'of the parallel conveyor. 2

Also method and apparatus according to FIGS. 5 to 8 are conceivable with more than one parallel conveyor in the same manner as described above for method and apparatus according to FIGS. 1 to 4 is described.

FIG. 9 shows a device in which an inventive device 30, as shown for example in the FIGS. 1 to 4 is shown, is used. The plant serves to continuously create (eg by collating) stacked groups of sub-products and to bond the sub-products of each stack by an adhesive bond. The decor is in the FIG. 9 shown as a schematic plan view and in the FIG. 10 as a three-dimensional partial view.

The device has a gathering section 10, by which a stream of the stack-shaped groups is generated, characterized in that a sub-product is added to each stack by a plurality of feeders 20 which successively open into the gathering section. The binding edges of the partial products are the leading edges and they are already aligned as closely as possible within each stack.

The stack-shaped groups are positioned from the exit of the gathering section 10 in a manner known per se in the compartments 11 of the cross conveyor 1 of the device 30 according to the invention, being pushed, for example, by a conveyor belt into the compartments 11, if they are in a deflection of an approximately horizontal or slightly inwardly sloping position, or they are introduced from above into the substantially horizontally conveyed compartments. In the compartments, the stacking edges to be bound are directed against the inside or against the bottom. From the compartments 11, the stack-shaped groups in connection with the FIGS. 1 to 4 described way passed to the parallel conveyor 2, through which they are conveyed in the adhesive binding device 40 necessary for the perfect binding position (edge to be bound directed downward and aligned in the conveying direction).

During conveyance in the compartments 11, the alignment of the edges to be bound of the partial products in the stacks can be improved by vibrating the compartments or the partial products can also laterally be aligned with one another in a manner known per se. Likewise, in the compartments, before they reach the entrance of the parallel conveyor, the stack thicknesses can be checked and auxiliary conveyors in compartments with too thin or thick, ie faulty stacks can not be activated, so that the defective stacks are not conveyed into the binding machine but, for example the next deflection of the conveyor compartments 11 dropped and can be disposed of accordingly.

FIG. 10 shows a three-dimensional representation of that part of the device according to FIG. 9 containing the inventive device 30. Like elements are designated by like reference numerals. Out FIG. 10 it can be seen that the cross conveyor 1 is designed as a circulating system with two pulleys. The radially projecting compartments 11 are mounted, for example, on two parallel circulating chains, the chains run over the pulleys.

For stacks to be tied with a waistband edge of 425 mm, as is the case for magazines, and a division distance in the cross conveyor 1 results for a performance of 15,000 copies per hour, a cross conveying speed of 0.34 m / s and a parallel conveying speed of 1.7 m / s. For an output of 18,000 copies per hour, the speeds are 0.42 and 2.13 m / s.

It proves to be particularly advantageous if the method described in the patent application WO-03/053831 (F557) is used for the collation of the stacked groups, wherein the groups are not created by collating but by bringing together scale flows of different partial products. The partial products of all shingled streams are arranged such that leading edges of the partial products are aligned for each group. From the leading end of the merged scale flows are then separated by gripping the aligned edges of the partial products one group after another and advantageously passed directly into the compartments 11 of the cross conveyor 1.

FIG. 11 shows in more detail an exemplary embodiment of conveyor compartments 11 for a transverse conveyor 1, as shown in the preceding figures. The conveyor compartments 11 are formed by a respective rigidly connected to a compartment floor 50, trailing wall 51 and a pivotally mounted in the compartment floor, leading wall 52. The leading wall 52 is controlled for example by a link 53, on the one at the lower end of the leading wall 52 arranged control roller 54 rolls, brought into an open position and is otherwise held by a not shown return means in a closed position. The compartments are so arranged on a rotating conveyor, eg chains (dash-dotted line 55) that they follow each other in a straight course of the chains as close to each other and that they in the areas of the guide wheel 56 for an introduction the flat objects 5 or stacked groups of partial products can be opened sufficiently.

FIG. 11 also shows Hifsfördermittel in the form of sliders 60, one of which is provided in each compartment 11. The slider 60 projects through a corresponding slot through the trailing wall 51 in the compartment 11 and is mounted on the outside of the trailing wall 51 by a longitudinal guide system 61. The slide movement parallel to the axis of the guide wheel 56 is controlled by a control link, not shown, on which the rollers mounted on the control rollers 62 roll.

For an adjustment of the compartments 11 to the thicknesses of the objects 5 or stacks to be processed, it is advantageous to make the pivotable mounting of the leading walls 52 displaceable in the compartment bottoms 50 such that the width of the compartment floor 50 becomes adjustable.

It is also possible, instead of in the FIG. 11 shown slide provided in each compartment 11 to provide an external slide or an arrangement of a plurality of slides and move in a direction transverse to the transverse conveying direction in the compartments, as for example in the publication mentioned above US 1760030 is described.

FIG. 12 shows a further exemplary embodiment of an auxiliary conveyor for a conveying compartment 11 of a cross conveyor of a device according to the invention. The figure shows a conveyor compartment 11 without trailing wall and looking in the transverse conveying direction. The auxiliary conveyor has two jaw-like clamping parts 70 (one visible), which are mounted on a displaceable in the area of the compartment floor 50 Carriage 71 are transversely movable to the transverse conveying direction and which are pressed against each other and from each other be removed. The carriage movement is controlled, for example, by a control link 73, on which a control roller 74 unrolls, which is arranged on a projecting from the compartment 11 slide part.
