Description

The invention relates to a Buchform- and -pressmaschine for pressing and rebating of books according to the preamble of claim 1.

From the DE 39 05 767 A1 a book forming and pressing machine is known, with a plurality along a closed, oval-shaped orbit continuously driven pressing devices and there arranged Falzeinbrenneinrichtungen. On one straight line of the transport system, the supply of the book block hinged in book covers and on the opposite straight line, the export of the molded and pressed books. During transport between import and export, the books are permanently housed in the pressing devices, so that the full transport time for the operations full-presses and folding forms is available. The books are included in the pressing devices over the entire surface up to the Buchdeckenfalzen.

The books are conveyed with a transfer device, which moves briefly synchronously with the pressing devices, obliquely from bottom to top between the open press plates. A reshaping of the rounded book block and orientation of the hinged book block to book cover is not provided within the pressing device. Instead preformed books in the transfer device are clamped the pressing devices are supplied. However, the fixation of this preforming can not be maintained until it is clamped by the press plates acting over the entire surface of the pages of the books, so that there is a risk that the preformation already taken will be lost by restoring forces and the books will be picked up obliquely by the pressing devices.

In the DE 44 22 783 A1 a Buchform- and -pressmaschine is described, in which a number of pressing devices arranged thereon Falzeinbrenneinrichtungen are arranged on a rotor about an axis of rotation intermittently driven rotor, with quasi tangentially arranged on the rotor circumference pressure plates. The books are recorded permanently from the import to the export in one and the same press device over the entire surface. The seam forming rails can be kept closed continuously.

With the help of a charging station, the books forwarded with their backs are first raised by means of a loading ruler with associated guide web, and then transported from below into the open, stationary pressing device under lateral support by the said loader and counter-rake from a loading table equipped with prism bars become. In slightly closed Falzformschienen and closed with or without pressure press plates then a loading temple lowers as a mold rail of a Nachformeinrichtung against the front section and presses the book block in the back, whereby the two book covers are pulled over Schrenz and intent in the joint against the Falzformschienen. Book block and book cover can be aligned relative to each other, while re-forming the book.

When erecting the books are pushed with their backs over the guide bar, which is associated with the risk of markings on sensitive book covers and can be lost when you put the book block in the book cover book shape. This also applies to lifting the books under the lateral support by the two rakes. The latter is also a time-consuming process and limited in conjunction with the then still in the stoppage of the rotor to be carried Nachform- and alignment process the clock performance of the book-forming and -pressmaschine.

The invention has for its object to provide a Buchform- and -pressmaschine of the generic type, which allows for high clock performance reliable and proper feeding and aligning the books in the pressing devices, with an already previously created book form preserving as possible and gently in the Pressing device is transferred.

This object is achieved by a books on the pages detected, from an upstream transfer position accepting book pliers, which transports the respective book in a vertical position between the open press plates of a pressing device in a reciprocating motion, and by an alignment table on the the book tongs set the book down with his back, for subsequent alignment and reshaping of the book within the pressing device. The books are transported by the book pliers in the fastest way directly between the press plates of the books over the entire surface receiving press device and gently set down on the alignment table, without the books are pushed over rakes or webs. A book form in the upstream submission position remains intact and can be further processed with the subsequent alignment and reshaping to a high quality product.

The dependent claims define preferred embodiments of the book forming and pressing machine according to the invention.

To form a shaft, the alignment table can be assigned lateral guide elements, so that the books are held in a vertical position after weaning. Preferably, when the book is deposited by the book pliers, the alignment table is positioned in a set-down position lowered relative to the height of the seam forming rails. From the settling position, the alignment table can be raised to a definable alignment position for positioning the book cover rebates at the level of rebate rails. It is advantageous if, after the displacement movement of the book pliers, the pressing plates for lifting the book are controlled by the alignment table in a first closed position, wherein a defined guide channel is presented with close guidance for the book.

In a preferred embodiment of the book forming and pressing machine according to the invention, the pressing devices are arranged with the arranged on them Falzeinbrenneinrichtungen on a rotor rotating about an axis. Preferably, the rotor is circumferentially driven intermittently, wherein the alignment of the books by means of the forming rail and the alignment takes place at a standstill of the rotor, which allows a relatively simple construction.

With the advantage of moving in a vertical plane press plates, the axis of rotation of the rotor is arranged in a horizontal position with a perpendicular orientation to the press plates, with substantially radially to the axis of rotation extending Falzformschienen. The supply of books through the book pliers can be done while the rotor is still rotating, the respective pressing device is moved with open press plates quasi from bottom to top in their transfer position. It is advantageous if, in the transfer position, the folding-incinerating device arranged on the pressing device is oriented horizontally with the folding-forming rails so that the force of gravity acts in the direction of the spine of the book. Preferably, the press apparatus is moved with the open press plates around the alignment table up to the takeover position so that the books are already settable on the alignment table when the press apparatus is still moved to its takeover position.

In a preferred embodiment of the book forming and pressing machine according to the invention, the book pliers are pivotally driven about an axis oriented perpendicular to the press plates, for turning and transferring the books from the upstream transfer position to the depositing position between the press plates.

With the advantage of a defined transfer of the books in the horizontal direction, i. in the direction of book height, the pivot axis of the book pliers in the horizontal direction is parallel to the format adjustable, for example. To change the reference edge when turning the books from the head or foot to book center or vice versa.

With the advantage of a defined transfer of the books in the vertical direction, i. in the direction book width, the pivot axis of the book pliers in the vertical direction is parallel to the format adjustable, eg. For changing the reference edge when turning the books of front cut on spine or vice versa, the back shape, whether straight or round, and the Rundungsmaß can be considered.

In a book-hanger 10, book blocks 2 are connected to book covers 3 to books 1. The Bucheinhängemaschine 10 is a Buchform- and -pressmaschine 40 downstream, achieved in the press-in of the book 1, a wrinkle-free and permanent bonding of the attachments of the book block 2 with the inner sides of the book cover becomes. This operation of the whole press is done in combination with the Falzeinbrennen, in which the book cover rebates 1c are formed and glued. The feeding of the books 1 to the book forming and pressing machine 40 ausgangs a book display 20 of Bucheinhängemaschine 10 is the subject of the present invention.

First, the operation of the Bucheinhängemaschine 10 based on Fig. 3 explained in more detail. Book block 2 are supplied from a book block transport chain 10.1 a circulation conveyor 10.3, with which the book blocks 2 are transported in an always vertical position astride support plates 10.4. They are thereby provided in the vertical conveying movement by glue rollers 10.6 on the attachments over the entire surface with adhesive and connected to a book cover 3 supplied via a book cover transport 10.2. The books 1 created thereby can subsequently be guided through pressure rollers 10.7.

In the further course, the books 1 move during their downward movement into a lying in the plane of movement of the support plates 10.4 book display 20, the books 1 with their front section 1 b on a wiper 20.5 put on, which has a passage slot 20.5a for passing the support plates 10.4. The wiper 20.5 is part of a book 20.1 and 20.2, with the books under constant support from the stripping 20.10 in a plane parallel to the movement plane delivery position 20.11 or 20.12 can be transferred (see Fig. 1 and 2 ), wherein the books 1 are supported during sideways movement with their front section 1 b on the wiper 20.5. In addition to the wiper 20.5 left and right support rails 20.6 and 20.7 are provided as further support means, which are closed after stripping the book 1 of the support plate 10.4 to a narrow Führungsmaß or with low clamping force.

To divide the book flow located in the circulating conveyor 10.3, alternately a first and a second book receiver 20.1 and 20.2 can take over the books 1 from the stripping position 20.10 and transfer them into a left and right display position 20.11 and 20.12 relative to the movement plane. The two book receivers 20.1 and 20.2 are arranged at a defined distance from one another in a guide rail 20.4 perpendicular to the plane of movement of the support plates 10.4 reciprocable carriage 20.3, so that simultaneously with the Ausführhub the first book 20.1 recording the second book 20.2 from its right delivery position 20.12 is moved to the stripping position 20.10 and vice versa.

As already stated above, the hanging follows the process of press-fitting and rebate baking, the books of the book forming and -pressmaschine 40 are fed with downward spine 1 a, while they are designed from the Einhängemaschine 10 with the back supra 1 a.

To the above-described book display 20 is followed by a double-book pliers 30, with the books 1 from the left and right display position 20.11 and 20.12 (as upstream transfer position) in a (from the perspective of Bucheinhängemaschine 10) second left or right delivery position 30.11 or 30.12 are convertible, the books turned 1 and placed with their backs 1 a directly on an alignment table 43.1 an alignment and Nachformstation 43 of the book forming and -pressmaschine 40.

The double-book pliers 30 has to take over the split book flow on a left and a right book pliers 30.1 and 30.2, which are about a pivot axis 30.3 gegengleich 180 ° back and forth pivotally, which is symbolized in the figures by corresponding movement arrows. The books 1 are laterally gripped with left and right jaws 30.4 and 30.5 in an area left free by the left and right support rails 20.6 and 20.7. The support rails 20.6 and 20.7 for this purpose are L-shaped, each oriented in the direction of book height, horizontally extending legs 20.8 and oriented in the direction book width, vertically extending leg 20.9.

By taking place in parallel to itself in the horizontal and vertical direction fulcrum adjustments 30.6, 30.7 of the pivot axis 30.3 - Fig. 3 symbolically represented by dashed double arrows - it is possible to settle the books 1 in a predetermined position on the alignment table 43.1.

With the horizontal pivot adjustment 30.6, the position of the books in the horizontal direction, in which the book height extends, can be fixed. In the book-hanger 10, the books 1 are transported astride the support plates 10.4 with the solid-fixed foot edge 20.13. In the book forming and pressing machine 40, however, a format-firm book center 30.13 is desired so that the books 1 are clamped centrally in the pressing devices 41. This reference edge change can be automated in format changes by a corresponding horizontal pivot adjustment 30.6 depending on the respective book height change.

With the vertical pivot adjustment 30.7, the position of the books in the vertical direction, in which the book width extends, can be fixed. After putting on the Abstreiforgan 20.5 the books 1 are performed with the front section 1 b as a fixed reference edge 20.14 from the book-hanger 10. The Buchform- and -pressmaschine 40 are meanwhile books 1 with the back 1 a as a fixed reference edge 30.14 supply. This reference edge change can be automated in format changes by a corresponding vertical pivot adjustment 30.7 as a function of the respective book width change, the back shape, whether straight or round, and the Rundungsmaß can be considered.

As described, the books 1 are deposited in the postforming and alignment station 43 with their back 1a on the alignment table 43.1. It is formed from two mutually parallel, the respective book 1 at its spine outer edges supporting prism bars 43.2, with inclined, flat support surfaces for the spine outer edges, the distance of the prism bars 43.2 to each other in relation to the book thickness is adjustable.

The transfer of the books 1 with the book pliers 30.1 or 30.2 takes place directly between the press plates 41.1 of the pressing devices 41, which are first controlled in a correspondingly open open position 41.11 and are closed after pivoting out of the book pliers 30.1 and 30.2 in a guide position 41.12 to form a defined guide channel with close guidance for the books to be aligned.1.

To form a holding the books 1 in a vertical position shaft 43.3 the alignment table 43.1 on book thickness adjustable, stationary side guides 43.4 are assigned, wherein the alignment table 43.1 upon adoption of the book pliers 30.1 and 30.2 supplied book 1 in a relation to the height of the Folded forming position 43.11 is controlled and for aligning and reshaping of the book 1 in a predefined alignment position 43.12 relative to the side guides 43.4 is raised, the books 1 are meanwhile supported by the press plates 41.1 (see 4 and 5 ).

The lifting of the alignment table 43.1 takes place only with a small stroke, so that no unnecessary performance restrictions result from this. Alternatively, the alignment table 43.1 could be fixed in said alignment position 43.12 and the side guides 43.4 would be moved downwards out of the effective area of the press plates 41.1.

With the raising of the alignment table 43.1, a forming rail 43.5, which can be moved up and down on a support arm 43.6 in a guide rail 43.7, initially lowers with a low pressure force on the front section 1 b of the book 1, and then to press the book block with an increased pressure force in the book cover back after detecting the book cover rebates 1 c through the Falzformschienen 42.1 and form, the alignment table 43.1 is possibly minimally lowered. The two book covers are pulled over Schrenz and intent in the joint against the Falzformschienen 42.1. Book block 2 and book cover 3 can be aligned relative to each other, with simultaneous re-forming of the book first

The book forming and pressing machine 40, which is only partially shown in the figures, consists of a left and a right book forming and pressing machine 40.1 and 40.2, which are essentially identically designed but intermittently driven by 180 ° out of phase. In each case, a plurality of pressing devices 41 are arranged on a rotor 40.3, the axis of rotation 40.4 is oriented perpendicular to the pressing plates 41.1 and extends horizontally, so that the pressing devices 41 rotate virtually overhead. The seaming devices 42 are also located on the rotor and run together with the pressing devices 41. Their folding form rails 42.1 extend substantially radially to the rotor axis of rotation 40.4.

The plane of movement of the pressing devices 41 is identical to the plane of movement of the respective book pliers 30.1 or 30.2, which feeds the books 1 to the pressing devices 41. This makes it possible to feed the books 1 while the rotor 40.3 is still being driven, with the respective pressing device 41 being moved with the pressing plates 41.1 in the open position 41.11 quasi around the alignment table 43.1, from bottom to top into the aligning and postforming station 43.

Ideally, the rotational movement of the pressing devices 41 then comes to a standstill when the book pliers 30.1 and 30.2 has deposited a book 1 to be processed on the alignment table 43.1 and has already swung back out of the effective range of the press plates 41.1, so that the pressing devices 41 immediately thereafter in their guide position 41.12 are controllable and the alignment table 43.1 with the book 1 in the alignment position 43.12 can be raised.

After completion of the alignment and Nachformvorganges the mold rail 43.5 is moved upwards out of the press plates 41.1 and the pressing device 41 is controlled in its clamping position 41.13, in which the books 1 are already exposed to a certain total pressure. In addition, the heated Falzformschienen 42.1 with increased Pressure closed to form the book cover folds 1c. The moment the forming rail 43.5 lifts from the front section 1b of the books 1, the rotor movement can begin to continue the pressing devices 41 one position at a time.

During their intermittent circulation, the pressing devices 41 pass through a pressing station, not shown, in which an increased pressing force from the outside on the press plates 41.1 can be applied during the rotor standstill, the actual Whole pressing the books 1. Finally, a Ausführstation 45 is provided in which the books. 1 the pressing devices 41 are removed again.
