Such a device may for example be part of a system for the production of photobook blocks or the like. For this purpose, a previously printed and / or exposed web of material is unwound from a roll, which preferably consists of paper, in particular photo paper, or film. Alternatively or additionally, the web unwound from the roll can be printed in a subsequent printing station. From the web are then separated by cross-cutting printed sheets. The sheets are folded or folded along a fold line, so that the fold line forms a folded edge. In an adhesive application station, the folded sheets are provided with adhesive before being stacked in a stacking station by joining two adjacent sides of the folded sheets together by the adhesive to form a common side. The overlapping folding edges of the sheets in the stack together form the back of the book block formed from the stack. Subsequently, the book block thus produced is removed from the stack forming station and transported to a subsequent station for further processing, which i.a. Also includes the device of the type mentioned, to provide the book block with a book cover. The book cover, which can alternatively be referred to as a cover, for example, is usually a thicker layer of paper or cardboard.

The assembly of book block and book cover is done by hanging and gluing book block and book cover together. This can take place during a vertical conveying movement by raising a substantially upstanding book block with its back first through the first conveyor from a lower position to an upper position. Prior to the actual assembly operation, the outsides of the book block are provided with adhesive in an adhesive application station while the book block is moved upwardly through the adhesive application station. Furthermore, the associated book cover is first to the back of the book block centered. This is done in an alignment station, wherein during this alignment process, the book cover is in a flat expanded shape and in a substantially horizontal orientation and is arranged above the adhesive application station. At this stage, the book covers are already provided with a centrally located pair of spaced creasing lines sandwiching therebetween a narrow central portion forming the spine of the finished book. With continued vertical conveying movement, the two halves of the centered book cover are folded in a landing station on the two outer sides of the book block. The two halves of the book cover come into contact with the glued outer surfaces of the book block. By pressing the book cover with the book block, an effective bond between book cover and book block is achieved.

The device shown schematically in the figures is used for assembling a book block and a book cover. Such a device, which may alternatively be referred to as Bucheinhängevorrichtung, is part of a plant for the production of books, which may be, for example, photo books. For this purpose, a previously printed and / or exposed web of material is unwound from a roll, which preferably consists of paper, in particular photo paper, or film. Alternatively or additionally, the web unwound from the roll can be printed in a subsequent printing station. From the web are then separated by cross-cutting printed sheets. The sheets are folded or folded along a folding or folding line, so that the fold line forms a folded edge. In an adhesive application station, the folded sheets are provided with adhesive before being stacked in a stacking station by joining two adjacent sides of the folded sheets together by the adhesive to form a common side. The overlapping folding edges of the sheets in the stack together form the spine of the book block formed from the stack. Subsequently, the book block now formed by the finished stack is removed from the stacking station and transported to the device in question here for joining the book block and book cover.

Hereinafter, the structure of the device for assembling book block and book cover based on FIGS. 1 to 3 with simultaneous explanation of the workflow, as shown schematically in Fig. 4 is shown described. In the illustration of the figures, the paper running direction or conveyor or transport direction and the process direction runs from left to right, which is indicated by the arrow A.

How the particular FIGS. 1 . 3 and 4 can be seen, the book blocks marked with the reference numeral "2" in horizontal orientation us thus transported in a horizontal conveying plane. Initially, the book block 2 moves with his back 2a ahead, which is formed from the superimposed fold lines of the individual layers. This Transport state can be in Fig. 4 recognize positions I and II. The transport is carried out by means not shown, which may have, for example, an endless circulating conveyor belt. The book block 2 is transferred to a rotary unit 4, which in the FIGS. 1 and 3 is shown schematically. The turntable 4 engages the book block 2 in its position II and rotates it by 90 °, so that it is brought with his back 2a at a contact edge 6 in abutment, in particular in Fig. 3 as well as in the FIGS. 4a and 4c shown position III is recognizable. By investing in the abutment edge 6 of the book block 2 is aligned with its back 2a with respect to a so-called. Machine zero edge, which is formed in the illustrated embodiment of the contact edge 6; In this way it is possible that book blocks with different formats can always be positioned at the same machine zero edge.

In the in the FIGS. 4a and 4c Position III thus shown, the book block 2 is positioned with two of its edges, so that only one degree of freedom in the transport direction according to arrow A is present.

Along the abutment edge 6 of his back there 2a there fitting book block 2 in the transport direction according to arrow A in the in the FIGS. 4a to c Position IV shown moved. This can take place, for example, by means of the rotary unit 4, if it is mounted correspondingly displaceable. Alternatively, however, a slide, not shown in the figures, can move the book block 2 accordingly by moving the book block 2 in position III (cf. Fig. 4 ) is released from the rotary unit 4 and engaged with the slider.

Moving to position IV according to Fig. 4 the book block 2 is conveyed to a set-up table, which at this time is in a horizontal position and is then folded up 90 ° in a vertical orientation. In the FIGS. 1 and 3 this table is shown recognizable in its already folded upright position and provided with the reference numeral "8". As Fig. 1 can also be seen, the table 8 is provided with two side strips 8a, 8b, which extend in the transport direction according to arrow A. and spaced from each other. These two side strips 8a, 8b serve as stops on the side edges of a book block 2 accommodated by the table 8, in order to fix the book block 2 transversely to the transport direction according to arrow A. With regard to different widths of the book blocks 2 with different formats is the (according to Fig. 1 Lower) side bar 8b along the surface of the table 8 arranged transversely to the transport direction according to arrow A slidably. The set-up table 8 is mounted on a frame 10 so as to be pivotable about a pivot axis (not shown in the figures) adjacent to the side strip 8b.

The (according to Fig. 1 upper) side bar 8a is stationarily mounted in the illustrated embodiment on the table 8 and thereby arranged and aligned so that they with the in the Figures 3 and 4c schematically illustrated contact edge 6 is aligned or forms a portion of the contact edge 6 when the table 8 is in its horizontal position, in which the book block 2 on the table 8 in the position according to Fig. 4 is recorded. By folding up the table in the in the FIGS. 1 and 3 shown upright position of the book block 2 located on the table 8 is also spent in a vertically upright position, the Fig. 4 marked with "V". So that the book block remains fixed during this also during the pivoting movement and in the upright position of the table 8, the table 8 is further not shown in the figures locking or engagement means (for example in the form of brackets) for releasably fixing the book block 2 on the Surface of the table 8 provided.

In the illustrated embodiment, the table 8 on the frame 10 is not only pivotable in the manner described above, but also linearly movable in the transport direction according to arrow A so that it can be moved in the direction of a sword box 12. This pivotal movement and this linear movement are generated by a drive, not shown in the figures. In Fig. 1 the table 8 is shown in a position immediately adjacent to the sword box 12. In the sword box 12 is a narrow box, which is arranged upright or vertically and extends parallel to the virtual plane, the from the table 8 in its upright position according to Fig. 1 is spanned. The sword box 12 consists essentially of two plates whose small distance from each other is substantially dimensioned so that they can accommodate a sword 14 between them. The sword 14 is disposed in the same vertical virtual plane as the sword box 12 and movably supported along a rail system 16 in the vertical direction. The raising and lowering of the sword 14 along the rail system 16 is effected by a drive, also not shown in the figures. In Fig. 1 the sword 14 is shown in its lower position. In order for the sword 14 to pass through the sword box 12 during its upward and downward movement, its lower edge 12a and upper edge 12b are open and form a corresponding slot-shaped opening.

In the figures, fingers not shown push the book block 2 from its position V on the table 8 on the sword box 12 in a position VI. A comparison of positions V and VI in Fig. 4a let recognize that they are in the same virtual level, in which the book block 2 is pushed accordingly in the direction of transport according to arrow A on the sword box 12. In doing so, the side edge 12c of the sword box 12 facing the table 8 engages in the book block 2 between two pages in its center, so that the book block in the position V with its one half on one side and its other half on the other side of the sword box 12 comes to rest. In order to avoid damage to the free edges of the book pages during this Aufschiebbewegung by pointing to the table 8 side edge 12c of the sword box 12, this side edge 12c of the sword box 12 in the illustrated embodiment according to Fig. 1 formed inclined relative to the vertical, thus to ensure a gradual and gentle engagement of the sword box 12 with its side edge 12c in the book block 2. In addition, in order to avoid marks and other damage on the inner sides of the book block, especially in the area of the back, the book block 2 is not only arranged by the arranged on the table 8 (in the upright position according to Fig. 1 lower) lateral bar 8b, but also supported by a strip-shaped support 17, which is arranged on the sword box 12, such as Fig. 1 can also recognize. In this case, the support 17 is adjustably mounted in the vertical direction and is set to a height in which it is in accordance with (in the upright position of the table 8 according to Fig. 1 lower) side bar 8b of the table 8 is aligned. The arrangement of the stationary side bar 8a on the table 8 and the adjustable side bar 8b on the table 8 and the likewise adjustable support 17 on the sword box 12 made so that the book block 2 with his back 2a at a certain vertical distance from the upper edge 12b of the sword box 12 is pushed onto the sword box 12, to prevent that the upper edge 12b of the box case 12 causes marks or other damage within the book block 2. As the side bar 8b on the table 8 is in a format change in the same way, the support 17 on the sword box 12 vertically adjusted at right angles to the transport direction according to arrow A. Preferably, on each of the two outer sides of the sword box 12 is a strip-shaped support corresponding to the in Fig. 1 illustrated edition 17 is provided, both supports are synchronously adjustable in the vertical direction and always lie at the same vertical height.

Furthermore, the arrangement and orientation of the table 8 in its upright position according to Fig. 1 be met with respect to the sword box 12 so that the sword box 12 engages centrally with its side edge 12c in the book block 2 when it is moved from the position V in the position VI on the sword box 12. So that book blocks or books can be processed with different thickness, the table 8 on the frame 10 is also stored so that it is in its upright position according to Fig. 1 additionally also transversely to the transport direction according to arrow A (and thus transversely to the plane of Fig. 1 ) is adjustable. In this way, the last degree of freedom, namely the variance of the thickness of the book block 2, eliminate, since the table 8 by the mentioned transverse adjustment in its upright position according to Fig. 1 a kind of averaging, based on the thickness of the book block 2, performs.

After arranging the book block 2 in its position VI on the sword box 12, the sword 14 leaves its in Fig. 1 shown lower position, moves through the sword box 12 upwards and engages with his at the upper edge 12b of the sword box 12 emerging (not visible in the figures) upper edge in the inside of the back 2a within the book block 2 to the book block 2 with continued upward movement take along accordingly and thus lift in the vertical direction of the sword box 12.

As the FIGS. 1 to 3 can also be seen, above the sword box 12 is a docking station 18, whose task is to align a book cover for joining with the book block 2 accordingly and create. Such book covers are in particular in Fig. 4 recognizable and marked with the reference numeral "20". The delivery of the book covers 20, which takes place substantially simultaneously with the delivery of the book blocks 2, takes place in the illustrated embodiment from the side, as the positions VII and VIII show, in which in the FIGS. 4a and 4c each a book cover 20 is shown recognizable. During the delivery and in the Fig. 4 shown positions VII and VIII and IX take the book covers 20, which are preferably made of cardboard or at least a thicker paper layer, a flat-spreading shape. For the transport of the book covers 20, the docking station 18 has a suction pad 19, to each of which a book cover 20 adheres with its upper side. The suction pad 19 is transverse to the conveying direction according to arrow A in the direction of in the Figures 2 and 3 shown double arrow B in the horizontal direction reciprocally movable.

After moving from the delivery position VII in the position VIII by a conveyor, not shown, the book cover 20 is centered with respect to two mutually spaced and mutually parallel groove strips 22 aligned, which then pressed into the surface of the book cover 20 to two spaced apart and transversely to the Longitudinal extent of the book cover 20 to form centrally extending grooves. While the groove strips 22 in the FIGS. 1 . 2 . 3 and 4a are clearly shown, the grooves produced by them in Fig. 4c on the book cover 20 located in position VIII indicated and indicated by the reference numeral "20a". As Fig. 4c further, the two grooves 20a enclose therebetween a strip-shaped portion forming the later spine 20b, and otherwise divide the book cover 20 into two halves 20c. With these two halves 20c, the book cover 20 later arrives in connecting engagement with the outsides of an associated book block 2, which will be described in more detail below. The groove strips 22 are moved and driven by corresponding handling devices, not shown, and together with such handling devices may form part of a groove station or landing station 18 not otherwise shown in the figures. As the Figures 2 and 4a can also be seen below the plane in which the book cover 20 is in their positions VIII and IX, and thus provided below the book cover 20 a counter strip 23, while the grooved rails 22 are arranged above this level and thus above the book cover 20. The counter strip 23 extends parallel to the groove strips 22 and lies in the middle between them, in particular Fig. 2 lets recognize. The counter strip 23 is raised and lowered by a lifting drive 23a and serves on the one hand as a kind of abutment against the upper groove strips 22 and on the other to impress a groove, not shown in the drawings on the inside of the book cover 20 in the middle between the two grooves 20a , Also, the counter strip 23 and the associated lifting drive 23a may also be part of a Nutstation or the landing station 18 otherwise not shown in the figures. By means of the groove strips 22 can in the book cover 20 in its position VIII according to the FIGS. 4a and c the grooves 20a embossed for the first time or, if in a previous step already corresponding grooves 20a have been generated in the book cover 20, these grooves 20a are even more pronounced. The formation or expression of the grooves 20a in the book cover 20 represents a preparatory measure before assembling the book block 2 and the associated book cover 20. Because the grooves 20a serve in particular to form a hinge in the manner of a film hinge in the book cover 20 to on the one hand to facilitate kinking or folding during assembly and, on the other hand, to facilitate the opening and closing of the later book.

How the particular Figures 3 and 4a can be seen, the book cover 20 is moved from the docking station 18 in the position IX, in which the book cover 20 is aligned with respect to the located in the position VI book block 2 centered. Fig. 4a Further, it can be seen that the previously described method steps for the book cover 20 and also their transport from the position VII to the position IX take place in a plane above a plane in which the book blocks 2 have been conveyed from the position I to the position VI.

How the particular FIGS. 1 and 2 can be seen, a Beleimungsstation 24 is located directly above the sword box 12. Now, if the sword 14 emerges during its upward movement from the upper edge 12b of the sword box 12, the book block 2 resting on the sword box 12 until then still in position VI is taken away by the sword 14 and raised accordingly. During this lifting movement of the book block 2 first passes through the gluing station 24 and is glued over its entire surface on both its outer sides. The vertical path or vertical plane along which the sword 14 moves and entrains the book block 2 in the upward direction is in FIG Fig. 2 indicated by a dot-dash line indicated by the reference numeral "Z". In particular Fig. 2 Furthermore, in the exemplary embodiment shown, the gluing station 24 has two arrangements provided on both sides of the conveying plane or conveying path Z from a glue application roller 25, a further distributor roller 26 in contact therewith and a pan containing the two rollers 25, 26 on. Both of these arrangements or at least the glue rollers 25 are between a working position in which they can be brought for a Beleimungsvorgang in touching contact with an outside of the Beleimungsstation 24 upwardly passing book block 2, and a rest position, in which the two glue rollers 25 in a larger Distance from each other than in the working position, so that a glue application to a Beleimungsstation 24, in particular in the downward direction, continuous book block is omitted.

As in particular the FIGS. 1 and 2 can be seen, is located above the gluing station 24, a so-called. Joining station 28, in which after leaving the gluing station 24 of the book block 2 is moved during its continued upward movement along the vertical conveying plane and the vertical conveying path Z. During this continued upward or stroke movement of the book block reaches with its leading back 2a in abutment with the underside of the later spine forming middle strip-shaped portion 20b ( Fig. 4c ) Book cover 20, which is in particular in the FIGS. 4a and c is located in the imaged position IX and thus is spread flat in the horizontal orientation and centered over the gluing station 24 with respect to the vertical conveying path or the vertical conveying plane X centered. As the book block 2 continues its upward movement, it carries along the strip-shaped central portion 20b of the book cover 20, while unillustrated engagement means in the joining station 28 ensure that with the continued upward movement of the book block 20, the two halves 20c (FIG. Fig. 4c ) of the book cover 20 up to this time in the position IX are applied to the outsides of the book block 2. The upward movement is continued in the joining station 28 until reaching an upper position, which in Fig. 4 is specified as position X. The docking station 28 further comprises two spaced-apart feed rollers 30, which are vertically arranged via a frame 32 along a rail system 34. Furthermore, a so-called. Back strip 36 is provided, which is aligned horizontally and sitting at the lower end of a guide device 38, in particular Fig. 1 lets recognize. By means of the guide device 38, the back strip 36 between the two Anreibwalzen 30 is movable in the vertical direction. The rail system 34 and the guide device 38 are mounted on a scaffold, not shown, to which also the required drives for the movement of the Anreibwalzen 30 and the back strip 36 are also installed, inter alia.

In the FIGS. 1 . 2 . 4a and 4b the Anreibwalzen 30 are shown in their upper position. For a better adhesion of the two halves 20c of the book cover 20 with the glued outer sides of the book block 2, the Anreibwalzen 30 in abutment against the outer sides of the two folded halves 20c of the book cover 20 brought. For this purpose, the two Anreibwalzen 30 enclose from above in its upper position X according to the FIGS. 4a and b located and provided with the book cover 20 book block 2, which together with the book cover 20, so to speak, the pair "book" 40 ( Fig. 4a and 4b ). During the subsequent vertical downward movement, the two nip rollers 30 roll along the outside of the book 40 and simultaneously exert pressure on the halves 20c of the book cover 20 to effect effective, bubble-free, high-quality bonding to the book block 2.

The back bar 36 is also in Fig. 1 shown in its upper position and can be moved by means of the guide means 38 in a lower position in which they are in contact with the outside of the in position IX ( Fig. 4a ) lying flat book cover 20 passes in the region of the central strip-shaped portion 20b. During the continued lifting or upward movement of the book block 2 in the direction of the upper position X, the back strip 36 is held by means of the guide means 38 in contact with the book cover 20 and at the same time in the upper position according to Fig. 1 carried. This results in an additional stabilizing effect to ensure the assembly of the book block 2 with the book cover 20 in the desired orientation.

After the book block 2, already provided with the book cover 20, has reached the upper position X and also the previously described grating process using the Anreibwalzen 30 is completed, a reversal of movement of the sword 14 takes place, which continues to book block 2 or now in the upper position X of the book block 2 and the overlying book cover 20 existing book 40 carries. The reversal of the direction of movement has the result that, in the exemplary embodiment shown, the blade 14 is guided along the same vertical conveying path or the same vertical conveying plane Z (FIG. Fig. 2 ) is lowered. Thus, the book 40 leaves, so to speak, backward the joining station 28 and also runs backwards through the gluing station 24. Meanwhile, both the Anreibwalzen 30 of the joining station 28 and the glue applicator rollers 25 of the gluing station 24 is opened in order not to hinder the downward movement and to avoid an undesired further application of glue.

With continued lowering or downward movement of the book 40 reaches the lower position VI and is thereby again on the sword box 12, now coming from above, deposed, while the sword 14 continues to retract into the sword box 12 until it in Fig. 1 reached shown lower position. Since in the lower position VI the applied on both sides of the sword box 12 book is now supported again at its downwardly facing free edge of the support 17 so that the book 40 rests with his back not on the upper edge 12b of the sword box 12, but of this is relieved and thus an engagement of the upper edge 12b of the sword box 12 is excluded with the interior of the book 40, there is no risk that marks or other damage inside the book 40 arise when removing the book 40 from the sword box 12.

For the removal of the book 40 from the lower position VI, a removal station 50 is provided in Fig. 3 is shown schematically. In the illustrated embodiment, the removal station 50 on a pair of pliers 52 which is mounted on a frame, not shown, movable in the horizontal direction and movable to the hanging in position VI book 40. Using two distance-adjustable jaws 52a, 52b, the forceps 52 engages the book 40 in the area of its edge portion adjacent to the back and pulls the book 40 from the position VI of the sword box 12 in the position XI, as in the FIGS. 4a to 4c can be seen schematically. In addition to those in the Figures 3 and 4a to 4c Pliers jaws 52a, 52b shown schematically, the pliers 52 also have two pressure bars, not shown in the figures, which are above the jaws 52a, 52b arranged opposite each other and similar to the jaws 52a, 52b are mounted variable pitch. The pressure bars are used to undergo the impressed by the Nutenleisten 22 grooves 20a on the outside of the book cover 20 of the now completed book 40 of a deformation, while the jaws 52a, 52b not only for the necessary intervention for the removal of the book 40, but at the same time also provide for a further stabilization of the finished book 40. For the movement of the forceps jaws 52a, 52b on the one hand and the pressure bars on the other hand, a drive means not shown in the figures is provided, which is designed and arranged such that the jaws 52a, 52b and the pressure bars to each other time-shifted in two-sided engagement with the book 40 and . Disengage from the book 40. Specifically, for engagement with the book 40, the jaws 52a, 52b are first driven against the sides of the book 40 before the pressure bars engage the grooves 20a. When you release the book 40, the movement takes place in reverse; First, the pressure bars and then the jaws 52a, 52b are disengaged from the book 40.

For removal to a subordinate station not shown in the figures for further post-processing, the book 40 is brought into a horizontal alignment according to position XII in the illustrated embodiment. For this purpose, the pliers 50 can be used. Alternatively, it is also conceivable, after releasing the pliers 50 from the book 40, to transfer the book 40 to an unillustrated further conveying device which transports the book 40 into the horizontal position XII and removes it.
