Description

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

After hanging the book block in the book cover is achieved by pressing the book a wrinkle-free and permanent bonding of the attachments of the book block with the inner sides of the book cover. In industrial book production, this operation of all-pressing takes place on so-called book forming and pressing machines in combination with the folding incineration, in which the book cover folds are shaped and glued.

By doing U.S. Patent 2,921,322 there is shown a book forming and pressing machine having a plurality of straight row, equally spaced pressing devices, each having a pair of variable distance pressing plates for exerting a pressing pressure on the sides of a book. The stationary pressing devices are associated with heated folding form rails, each pairwise with a variable distance opposite, for forming the Buchdeckenfalze. The folding mold rails are located on a front and back movable trolley and also serve as a means of transport to gradually move the books from station to station, and then return to receive and transport a subsequent book to its original position. Thus, the hemming is done by repeated brief pushing the Falzformschienen, which is why higher temperatures in the Falzformschienen are required, which are particularly critical for heat-sensitive ceiling materials.

In the DE 10 2004 061 995 A1 is a further development of the aforementioned Buchform- and -pressmaschine described, in which the Falzeinbrenneinrichtungen are on means of transport, which are guided in a closed orbit, so that the books, from one and the same pair of Falzformschienen constantly gripped, cyclically advanceable from pressing station to pressing station are. The books are no longer released by the folding mold rails, whereby more time is available for the action of heat on the ceiling material. The disadvantage is that during transport, the books are held solely by the Falzformschienen in Buchdeckenfalz.

In the EP 384 129 B1 there is provided a book forming and pressing machine under protection with a plurality along a closed, oval-shaped orbit of continuously driven pressing devices and seaming means arranged thereon. 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. The whole pressing takes place with permanent, all-over recording of the books in the pressing devices and the folding mold rails can be kept constantly closed. A disadvantage is the considerable design effort for the transport system with the rotating pressing devices and the means for feeding, aligning and running the books in or out of the continuously moving pressing devices.

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

By having u.a. the drive members for generating the pressing pressure when whole pressing on the revolving rotor are arranged and which must be absorbed in the rotor structure acting on the books for full pressing pressure forces results in a complex and heavy construction for this type. The resulting large mass forces limit their cycle performance. This is also limited by the fact that a supply of books in the pressing devices can be made only when the rotor has come to a standstill, and that in addition to the feed and the alignment and reshaping has to be done in the standstill phase. With the pairwise arrangement of the pressing devices on the rotor an increase in performance is achieved. However, it requires a not inconsiderable additional expenditure in the import and export of the machine for the two parallel book streams.

A disadvantage of the known Buchform- and -pressmaschinen with rotating pressing devices is that they require a significant footprint.

The present invention is based on the object, a Buchform- and -pressmaschine for pressing and rebating of hinged in book cover book block to provide in accordance with the preamble of claim 1, which ensures a reliable and proper pressing and crimping of books with a compact design and allows high clock performance.

Changes to the description

This object is achieved in that the pressing devices with the Falzeinbrenneinrichtungen in a closed, a substantially vertical plane spanning orbit are driven circumferentially, wherein the pressing devices are arranged with the Falzeinbrenneinrichtungen on a rotor rotating about a horizontal axis, the rotor rotational axis perpendicular to the Press plates oriented, and so that the press plates are oriented parallel to the plane spanned. With the advantage of safe transport, the books are constantly being taken up in one and the same pressing device during their circulation. The folding form rails can be kept constantly closed for a gentle Felzinbrennen. The vertical arrangement of the orbit results in an extremely compact installation. Only a small footprint is needed. With the pressure plates oriented parallel to the orbital plane, the books accommodated in the pressing devices are in this orbital plane at every stage of their transport. An inlet and outlet of the books is thus also given in principle in the movement of the pressing device, so that higher cycle rates of Buchform- and -pressmaschine are possible.

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

Preferably, the Falzformschienen the Falzeinbrenneinrichtungen are always oriented transversely to the conveying direction of the pressing devices.

The pressing devices with the press plates can be positioned in an open position, guide position and / or closed or clamping position. Preferably, a format adjustment to book thickness is provided in the positioning. In the closed or clamping position at least one holding force between the press plates can be applied, which is sufficient for a safe transport of the books in the rotating pressing devices.

In a further embodiment, it is provided that the Falzeinbrennschienen the Falzeinbrenneinrichtungen for forming, holding and / or releasing the Buchdeckenfalze are actuated. Preferably, the Falzformschienen in the release position on a large distance to the spine on.

It is advantageous if the pressing devices and the associated Falzeinbrenneinrichtungen be closed and openable about book center, as well as the desired book shape is formed symmetrically to the book center.

Preferably, the pressing devices are driven intermittently with the Falzeinbrenneinrichtungen so that in an advantageous refinement along the orbit stationary workstations for feeding, aligning, Nachformen, press-fitting and / or running the books can be arranged.

Advantageously, a stationary feed and alignment station with a horizontally arranged, the book in the back region supporting alignment table and a lowerable on the front section mold rail. The alignment does not take place on the moving book and can be conveniently observed from the outside and corrected if necessary.

With the advantage of a higher cycle performance, the books are fed in the spanned plane of the orbit substantially radially to the orbit of the pressing devices, wherein the feed already takes place when the respective pressing device is still in the forward movement to the feeding and aligning station.

It is advantageous if the actual pressing of the books is carried out in at least one stationary pressing station by additionally applying a high pressing force to the pressing plates located in the clamping position by pressure means supported in the frame. The pressing devices themselves do not have to apply this high pressing force, but only offer a much lower holding force. They can be designed to be much lighter and simpler, keeping the moving mass of the circulating system small and allowing for a further increase in clock speed.

Advantageously, a stationary delivery station for gripped carrying out the molded and pressed book, wherein the pressing device is controlled in the guide position with minimally open press plates and the books are pulled out by means of folded in the book case folds Falzklemmschienen from the respective pressing device, for transfer to a subsequent transport system. Even books adhering to the press plates are reliably and quickly retrieved from the press devices. Preferably, the Falzklemmschienen are located on a moving in said orbit pivot arm which approaches in the same conveying direction of the respective pressing device and moves when pulling out of the books in the opposite direction of the pressing device.

To further increase performance, two arrangements of rotating pressing devices can be arranged parallel to each other. With the advantage of the alternate, immediate acquisition of running from an upstream Bucheinhängemaschine books, the two arrangements are driven by 180 ° out of phase.

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, in which with the pressing of the book 1, a wrinkle-free and permanent bonding of the attachments of the book block 2 is achieved with the inner sides of the book cover. 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 book forming and pressing machine 40 according to the invention described below is connected via a book holding 1 constantly holding book 20 with associated, reciprocating pincers 30.1 and 30.2 in direct coupling to the book-hanger 10, so a separate clocking the books 1 not is required. Nevertheless, it can also be used as a single machine with a corresponding single-stroke device.

Based on Fig. 3 First, the operation of Bucheinhängemaschine 10 is explained with the book release 20. Book Blocks 2 are from a book block transport chain 10.1 fed to 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 of the books get 1 during their downward movement in lying in the plane of movement of the support plates 10.4 book release 20, the books 1 with its front section 1 b on a wiper 20.5 put on, which has a passage slot for passing the support plates 10.4. The wiper 20.5 is part of a book-holder, with which the books 1 with additional support by lateral support rails 20.6 from the stripping 20.10 in a movement plane parallel offset delivery position 20.11 and 20.12 can be transferred.

To divide the book flow located in the circulating conveyor 10.3 alternately a first and a second book holder can take the books 1 from the Abstreifposition 20.10 and in a move to the left and right delivery position 20.11 and 20.12 transfer (see Fig. 1 and 2 ).

The book forming and pressing machine 40 shown in the figures consists of a left and a right Buchform- and - press machine 40.1 and 40.2, which are substantially identical in design, but are intermittently driven by 180 ° out of phase for processing the split book stream. 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 devices 41 and extends horizontally, so that the pressing devices 41 rotate virtually overhead in a vertical plane. The seaming devices 42 are also located on the rotor 40.3 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 Buchform- and -pressmaschine is designed to ensure that the books 1 are constantly included in one and the same pressing device 41 and that the heated by heating rods 42.2 Falzformschienen 42.1 can be kept constantly closed for gentle Falzeinbrennen.

The pressing devices 41 are formed of a pair of mutually variable distance pressing plates 41.1, which are received on actuating arms 41.2 symmetrical about book center in an open position 41.11, 41.12 guide position and a clamping position 41.13 are adjustable. The actuating arms 41.2 are guided in a guide rail 41.3 fastened to the rotor 40.3. The control means for actuating the actuating arms 41.2 and thus the pressing plates 41.1 may be pneumatic, hydraulic or electric drive means or engage in mechanical cams. For the sake of clarity, a concrete execution and representation in the figures has been omitted.

The seaming mold rails 42.1 of the seaming devices 42 are accommodated on actuating arms 42.3, which are displaceably guided in guide rails 42.4 fastened to the rotor 40.3 and can be actuated symmetrically via book center by means of control means, not shown, for forming, holding and / or releasing the book cover seams 1c by the seaming mold rails 42.1 , In the release position, the Falzformschienen 42.1 at a large distance to the spine, whereby a feeding and Wegführ the books 1 in the plane of movement of the pressing devices 41 is made possible.

Due to the intermittent rotor movement, the possibility arises in stationary positions of the pressing devices 41 with fixed workstations to act on the books 1, for example for feeding, aligning, postforming, pressing in and carrying out.

First, the feeding and aligning station 43 will be described. It is located in a place where the pressing devices 41 are oriented horizontally with the Falzeinbrenneinrichtungen 42, for receiving the books 1 with downwardly facing back 1 a. As already explained above, the books 1 are laid out from the book-hanger 10 in a left and right delivery position 20.11 and 20.12 with the back 1a pointing upwards.

The feeding and aligning station 43 is preceded by a double-book pliers 30 with which the books 1 from the respectively left and right delivery position 20.11 and 20.12 (as upstream transfer position) in a second left or right delivery position 30.11 or (from the point of view of Bucheinhängemaschine 10) 30.12 are convertible, the books turned 1 and placed with their backs 1 a directly on an alignment table 43.1 of the feed and alignment station 43.

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 pivotable about a pivot axis 30.3 gegengleich 180 ° back and forth, which in the figures by appropriate Movement arrows is symbolized. The books 1 are laterally engaged with left and right jaws 30.4 and 30.5 in an area left clear by the support rails 20.6. The support rails 20.6 are formed for this purpose L-shaped.

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 placing on the wiper 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 feeding and aligning 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 and 30.2 takes place directly between the press plates 41.1 of the pressing devices 41, which are first controlled in the open position 41.11 and after swinging out the book pliers 30.1 or 30.2 be closed in the 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 Folding mold rails 42.1 lowered Absetzposition 43.11 is controlled and for aligning and reshaping of the book 1 in an 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 is lowered on a support arm 43.6 in a guide rail 43.7 movable up and down mold rail 43.5 initially with a low compressive force on the front section 1 b of the book 1, then after detecting the book cover rebates 1c by the Falzformschienen 42.1 the Press book block with an increased pressure force in the book cover back and reshape, 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 movement plane of the respective book pliers 30.1 and 30.2 is identical to the plane of movement of the pressing devices 41. This allows feeding the books 1 with still driven rotor 40.3, wherein the respective pressing device 41 with 41.11 controlled in open position pressing plates 41.1 quasi around the alignment table 43.1 around, from is moved bottom up in the alignment and Nachormstation 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 pressing 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 and are held securely at least for the rotary transport. In addition, the heated Falzformschienen 42.1 closed with increased pressure to form the Buchdeckenfalze 1 c. 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 44, in which an increased pressing force can be applied from the outside to the pressing plates 41.1 during the rotor standstill, for the actual whole pressing of the books 1. In a rack frame 44.1, pressure plates 44.2 are received via linear guides 44.3 can be opened and closed by hydraulic pressure cylinders 44.4 and act on pressure pad 41.4 of the press plates 41.1.

Finally, a delivery station 45 is provided, in which the books 1 are removed from the pressing devices 41 again. It has for the alternate removal of the books 1 from the two, se separate book forming and -pressmaschinen 40.1 and 40.2 on a left and a right book gripper 45.1 and 45.2, which are pivotable about a pivot axis 45.3 to each other back and forth, which in the Figures symbolized by corresponding movement arrows. The books 1 are detected in the book cover crease 1 c with a left and right Falzklemmschiene 45.4 and 45.5 and pulled out of the guide position 41.12 controlled pressing devices 41, for transfer to a left or right delivery position 45.11 and 45.12. For detecting the book cover rebates 1c, the folding form rails 42.1 are retracted in the release position. The books 1 are then taken over by a transport system, not shown, and led away from the book forming and pressing machine 40.
