EP2457738B1 - Method for binding book blocks with endpaper - Google Patents

Description

The invention relates to a method for operating a transport device for processing book blocks according to the preamble of claim 1.

Bookbinders are increasingly being confronted with having to produce book blocks for hardcover production in small series, often with an edition of a book. Usually, the contents of such books are produced by printing machines which have short changeover times. Most often, short runs are made with digital presses that allow you to dynamically change the print content. This allows a book to be printed in sequence and further processed into a book block. This happens mostly in-line, i. the required process steps from letterpress printing, folding and collation of the printed sheets as well as adhesive binding run until the ready-bound book is present directly behind one another and in a plant, which is also referred to as Buchstrasse.

In adhesive bonding, single sheets and / or folded printed sheets previously gathered into a book block are processed on their backs by milling and then glued. Thereafter, an envelope is pressed against the spine and thereby firmly adhered to the back of the book block. If a flexible envelope is used for this purpose, the finished product is referred to as sticky Paperback (softcover), while the use of a hard cover speaks of a hardcover.

In hardcover production, the book block is provided with attachment sheets, which are glued to both sides of the book block with a thin glue trace. In the finished book, these attachment sheets serve as a hinge for the envelope. In order to align the attachment sheet clean and flush with the back of the book block, they are preferably fed only after milling. Overlapping the spine of the book then a Fälzelstreifen is attached, which is glued, for example, with hot glue or PUR on the back of the book block. The fälzelstreifen attached in this way ensures that the book block is held together. In a next step, the book block is cut to the intended format and finally stuck a firm envelope to the two header sheet.

From the CH 325096 a compact adhesive binder is known, which has a transport device with a closed orbit and arranged in the region of the orbit processing stations. In this case, the transport device is designed as a turntable with peripheral pliers receptacles, in each of which a book block receiving pair of jaws is arranged. Because the jaws hold the book block during the entire processing can be in such a perfect binder, the attachment sheet at best together with the book block, ie before the back processing, resulting in the already mentioned above quality problems.

With the EP 1344655 A2 is an especially suitable for short runs perfect binder with a arranged after the milling feeder for the attachment sheet known. It is a linear, relatively long-building system with several in a row successively arranged processing stations and with a step-by-step forward book block transport, which is realized by a reciprocating transport device. In this case, the subsidized standing on his back book block is detected in its lower part on both sides by a transport device belonging to the clamping rail, which the book block transported by the milling device to the feed unit for the attachment sheet. There, the book block is transferred to an attacking in its central region retaining clip. Immediately thereafter, the clamping rails are released and fed both the attachment sheet and the Fälzelstreifen. In the meantime, the two clamping rails run back to their original position to take over the next book block. Simultaneously with the supply of the next book block, a rear area of the clamping rails takes over the promotion of already provided with attachment sheet and Fälzelstreifen book block to the next processing station.

However, the described return stroke of the clamping rails is slower than the supply of auxiliary sheet and Fälzelstreifen, i. The book block processed in this station is already preparing for further processing, as the clamping rails have reached their starting position. Due to the reciprocating transport device thus the cycle time of the adhesive binder is unnecessarily prolonged.

In addition, the clamping rails compress the book block near his back and thus compress it in its lower area. In the attachment sheet feed unit, the upper block of the book block is caught by the retaining clip while the clamping bars are still engaged. Then open the clamping rails to clear the way for the supply of the attachment sheet. This gripping the clamping devices brings a disturbance in the book block, which can lead to inaccuracies and shifts. If it is a voluminous book block, this is durchgewalkt, because the air contained in the book block must first escape to the outside. In this case, the previously generated milling pattern can be damaged, which leads to problems in the sequence of glue application and thus in the quality of the final product. In order to achieve the required precision in the described transfer of the book block from the transport device to the retaining clip is also a relatively high technical effort required. Finally, the attachment sheets can be supplied to the book block only during a standstill phase.

CH 414 544 A relates to a method for binding books on perfect binding machines, which makes it possible, labor-saving way attach the headers so that a clean connection between the book block and book cover is guaranteed. The attachments are attached to the book block in the perfect binding machine only after the milling or cutting away the Bogenfälze the book block forming sheet. The attachments can be attached to the book block before the gluing of his back, so that they are detected by gluing with and adhere to the book block.

Out DE 100 57 599 A1 is a device for producing book covers with a cardboard feeder for feeding separated from a cardboard magazine cover cardboard and a back insert has become known. The device has a utility feeder for feeding reference utility isolated from a utility magazine, wherein the supplied reference utility are formed with grippers taking over, past a glue application roller and with the supplied cover cardboard and the back insert zusammenfügendem Nutzenzylinder. The apparatus is further provided with a wrapping and pressing device laying the projecting reference edges around the paperboard edges and pressing the book covers, and with an expander for laying the book covers in stacks, and with a utility feeder, paperboard feeder, utility cylinder and wrapping and Andrückvorrichtung, wherein the Nutzenzuführung, the card feeder and the impact and Andrückvorrichtung are each driven independently.

Object of the present invention is to provide a method for operating a closed orbit having transport device for the processing of book block with a suitable for short runs, compact perfect binder, can be supplied with the attachment sheet after back processing to the book block and with the quality of Perfectly binding and books can be improved with reduced technical effort and a higher performance can be achieved.

According to the invention, this is achieved by a method having the features of claim 1.

For this purpose, the clamping devices are attached to or in the transport device and each have an outer pliers and arranged in the outer pliers inner pliers for the book block on. Due to this arrangement of pliers in a pair of pliers, the book block can be held throughout its residence time in the perfect binder by the inner pliers, while the outer pliers for feeding the attachment sheet is opened, thus creating the necessary space for the attachment sheet. Therefore, neither backward strokes nor encompassing of the clamping devices are required and the associated disadvantages of the prior art are eliminated. In addition, the arrangement of two such pliers allows book blocks to be picked up regardless of their block thickness and other format dimensions, i. each of the consecutive clamps can receive and transport a book block of different dimensions.

In a first embodiment of the invention, the outer pliers have a fixed and a movable pliers half and the inner pliers two movable pliers halves. By radial displacement of both the movable pliers half as well as the inner pliers, required for the supply of the attachment sheet radial clearance on both sides of the book block holding inner pliers can be created in a particularly simple manner. The pliers allow quick opening and closing while maintaining secure and defined support for the book blocks, increasing the performance of the perfect binder and improving the quality of the perfect binding.

According to the invention, the outer pliers have two first holding elements and the inner pliers have two second holding elements, wherein the holding elements are each arranged pivotably about a common axis of rotation. Even with this alternative embodiment of the clamping device, the two pliers can be relatively easily and independently opened and closed again as needed.

In the outer tongs, i. in the two holding elements each one of these penetrating, pocket-like recess is arranged. The recesses allow a particularly simple feeding of the attachment sheet through the holding elements of the outer pliers through, wherein the attachment sheet in the clamping devices initially stored in the amount of bag bottom and later fed to the respective book block and pressed against this. Due to the short path of the attachment sheet bottom of the bag results in a relatively low drop height, thereby avoiding a "jumping" of the attachment sheet and their precise bonding with the book block can be guaranteed.

In a third embodiment of the invention, the clamping devices each have a first pair of pliers attached to or in the transport device and a second pliers for the book blocks at the platen attachment station, the second pliers being disposed above the first pliers and spaced therefrom. Both the first and the second pliers each have a first and a second pliers half, wherein at least one pliers half is designed to be movable relative to the respective other pliers half. Due to the separate training and arrangement of the second forceps, the first forceps can be made easier.

In doing so, the book blocks are separated from the clamping devices, i. from the first pliers, first grabbed in a lower area and conveyed to the processing stations. A book block conveyed to the further processing station is grasped in an upper area by the second clamp, after which the corresponding clamping device is opened. Subsequently, the insertion of the at least one header sheet in the open clamping device takes place. Thereafter, the clamping device is closed again and then solved the second pliers, so that provided in this way with the attachment sheet book block is free again and can be promoted to the other processing stations.

In the pliers variants described, the attachment of the attachment sheet is carried out in two steps, i. In a first step, the attachment sheet above the book block and laterally spaced from this introduced into the respective clamping device and only lowered in a second step to the height of the book block and pressed against this. As a result, in the second step, the drop height of the attachment sheet can be reduced and thus a precise bonding with the book block can be ensured. Of course, the attachment of the attachment sheet can also be done in a single step.

At the landing station for attachment sheet and / or on the clamping devices, at least one reading device for identifying the attachment sheet is arranged. Identification features of the attachment sheets can thus be determined and compared with already-read identification features of the respective book block. If the attachment sheets do not fit the corresponding book block, a discharge of the book block or a corresponding interaction of the machine operator is triggered.

The transport device is driven continuously and the attachment sheets are each fed to a forward moving clamping device in the transport direction. In this way, the performance of the perfect binder can be maximized because there are no downtimes.

In an alternative solution, the transport device is driven in steps and the attachment sheets are each fed to a stationary clamping device. Because the book blocks are not moved, the landing station for the attachment sheet can be made easier.

Particularly advantageous, the processing stations and in particular the landing station for attachment sheet each have a self-propelled. As a result, the processing stations can be operated independently of each other and optimized for time-critical processes.

Finally, the orbit of the transport device is circular, oval, polygonal or formed as a shapeless curve, whereby the transport device is easily adaptable to any conceivable application.

Further advantageous features emerge from the dependent claims, the following description and the drawings.

The Fig. 1 shows a plan view of an adhesive binder 7 for processing book blocks 8 to bound books that can be mounted later in a book street in a hardcover (Hardcover). The perfect binder 7 is operated by a motor designed as a drive, not shown. Of course, a hydraulic or a pneumatic drive member or multiple drive members can be used. The perfect binder 7 has a transport device 9 and a number of processing stations 10. The transport device 9 is designed as a round table 12 revolving around an axis 11 with a closed circular orbit 13. The table 12 has at its periphery six equally spaced apart tong receptacles 14, which each receive a clamping device 1 to 6 for the book block 8. The clamping devices 1 to 6 are designed as Klebebinderzangen each with an outer and inner pliers 15, 16 ( Fig. 2 ). The arranged at a distance of 60 ° outer pliers 15 each have a fixed and a movable pliers half 17, 18, the latter being connected to open and close the Klebebinderzangen with suitable lifting mechanisms, not shown. During operation of the adhesive binder 7 describe the clamping devices 1 to 6, ie the outer and inner pliers 15, 16 together a circumferential path, concentric with the orbit 13 of the table 12. The processing stations 10 are arranged in the transport direction 19 of the table 12 behind each other and either below or above the table 12. Of course, the processing stations 10 can also be arranged next to the table 12.

In Fig. 2 , which shows the adhesive binder 7 from the top side, a part of the processing stations 10 can be seen in more detail. As the first processing station 10, a feed 20 arranged below the table 12 is provided for the book blocks 8. To save cycle time, the feeder 20 is designed as a feed star, which does not require a return stroke for conveying the next book block 8. The book blocks 8 are fed from below and either during standstill or the run of the perfect binder 7. Alternatively, the feed can be arranged above the table 2, laterally or tangentially. It can also be installed here a vibrator, not shown here, which cleans the book block clean. In the feeder 20 and the format of the book block 8 can be measured or identified with a reader, also not shown.

Immediately after the feed 20, a second processing station 10 designed as a back-processing device 21 is arranged, which serves to create a straight and roughened back of the book block 8. This is followed by the third processing station 10, an intermediate opening table 22, which is followed by a side gluing unit 23 also arranged below the table 12 and a fourth and fifth processing station 10 designed as a landing station 24 for two individual attachment sheets 25.

The FIG. 3 shows in an enlarged view in particular the docking station 24 and currently located in the area clamping device 5. The above the transport device 9 arranged piercing station 24 has a magazine 26, a take-off roll 27, a feed roller 28 and a pair of distribution rollers 29 for the attachment sheet 25, as well between the rollers 27, 28, 29 extending, not shown here conveyor.

Like the clamping devices 1 to 4 and 6 also has the in Fig. 3 enlarged clamping device 5 shown in addition to the outer pliers 15 each disposed within the outer pliers 15 inner pliers 16, which has two formed as a plate, movable pliers halves 30, 31. In the outer region of the two tong halves 30, 31 engages on both sides in each case an actuating bolt 32, which extends through the table 12, the other end connected to a drive, not shown and controlled by a separate control, for example via a control cam, by motor or by hydraulic. When the outer pliers 15 are open, the book block 8 with the inner pliers 16 in the pliers receptacle 14 can be moved radially and relative to the outer pliers 15.

Corresponding Fig. 4 Make a glue unit 33 and a Fälzelstation 34, the sixth and seventh processing station 10 of Klebebinders 7, followed by an eighth and ninth processing station 10 formed further Seitenleimwerk 35 and a pressure station 36 for a tenth processing station 10 forming, designed as a drum feeder Envelope feeder 37 provided Envelopes 38. The eleventh and last processing station 10 is a display 39. The processing stations 10 each have a self-propelled 40 advantageously designed as a servomotor, wherein in FIG. 1 schematically and representatively such a self-propelled 40 is shown for the docking station 24. Of course, the processing stations 10 can also be driven together in groups.

The table 12 is seated on a stand 41 and rotates driven about its axis 11. For this purpose, the axis 11 is mounted in the stand 41 and connected via a connecting element 42 fixed to the table 12. The stand is fastened to a platform 44 standing on the ground by means of feet 43.

In the Fig. 5 Fälzelstation 34 shown in detail has a Abrollwalze 45 for a Fälzelbahn 46, a counter roll 47, a side knife 48, two feed rollers 49, a Ablängmesser 50 and a lifting table 51 for cut-to-length Fälzelstreifen 52nd

In Fig. 6 the combined with the display 39 pressing station 36 is shown in detail. The pressing station 36 has two lifting tables 53, 54 lying one above the other.

The lower lift table 54 has two lateral, adjustable to the book thickness press plates 55 and a one-sided downwardly pivotable, cooperating with the display 39 bottom flap 56. The upper lift table 53 has a corresponding recess 57 for the passage of each of the book block 8 and the Envelope 38 books 58 formed in the direction of delivery 39 on. On the upper lifting table 53 not shown centerings are mounted, which align the envelope 38 to the corresponding book block 8.

The cooperating with the pressure station 36 and in Fig. 4 Envelope feeder 37 shown in more detail has a magazine 59 and a withdrawal drum 60 for the envelopes 38. Between the withdrawal drum 60 of the envelope feeder 37 and the upper lifting table 53 of the pressing station 36, a conveyor belt 61 and above the conveyor belt 61 scoring wheels 62 are arranged. Likewise, not shown Leimspritzdüsen for the side gluing of the envelope 38 may be mounted above the conveyor belt 61.

The perfect binder 7 is part of a system, not shown here, consisting of a digital printing machine, preferably from a roll of paper sequentially generates sheet for at least one book 58, a signature folder, the signature forms from the sheet, and from a gathering machine, which to solve the signatures Book block 8 is stacking. In a subsequent operation, these book blocks 8 can also be thread-stitched. Subsequently, loose or thread-stitched book blocks 8 are automatically transferred to the perfect binder 7. The system is controlled by a higher-level line control, which also transmits and coordinates the print data in an integrated workflow. The line control is also used for process monitoring. Of course, the perfect binder 7 can also be operated in a different system or separately, so that both an automatic and a manual loading of book blocks 8 or envelopes 38 is possible.

During operation of the adhesive binder 7, the book blocks 8 are successively fed by means of the feed 20 from a feed conveyor, not shown, for example a conveyor belt, taken over and handed over with a required for the subsequent back processing notice from below to the clamping devices 1 to 6 of the rotating table 12. In this case, the feeder 20 sets the book blocks 8 which have been delivered lying, so that they can be taken over by the respective clamping device 1 to 6.

In the specific case of Fig. 1 and 2 There, the book block 8 is first received by the appropriately controlled pliers halves 30, 31, ie firmly clamped in the self-closing inner pliers 16. Immediately thereafter, the movable pliers half 18 is displaced radially and away from the center, which also closes the outer pliers 15 and the book block 8 comes to rest together with the inner pliers 16 on the outside of the pliers receptacle 14, such as in the shortly before Open located clamping device 6 of Fig. 3 shown. In this regard, it should be noted that the numbering of the clamping devices 1 to 6, in spite of the rotating table 12 and the constantly changing assignment of the clamping devices 1 to 6 to the individual processing stations 10, has been retained in all figures to the assignment of figures representing only details facilitate.

By appropriately rotating the revolving table 12 in the transport direction 19, the clamped book block 8 moves over the back-processing device 21 (FIG. Fig. 2 ). In this case, the back processing, ie in the from the pliers 15, 16 downward projecting, not shown notice of the book block 8, the fibers of the paper are exposed by milling so that the later applied with the glue unit 33 back glue optimal connection with the book block. 8 can go down. In the position of the intermediate opening table 22, both the outer pliers 15 and the inner pliers 16 are opened, so that the book block 8 is released, sinks on the intermediate opening table 22 and thereby forms a new notice for further processing. By folding down the intermediate opening table 22 downwardly, a bad book block 8 can also be ejected in the area of this processing station 10. During the subsequent crossing of the Seitenleimwerkes 23 is applied to both the front and on the back of the recorded again by the pliers 15, 16 book block 8 a glue track for subsequent attachment of the attachment sheet 25 on the book block 8.

For this purpose, the rotating table 12 continues to rotate about its stand 41, so that the previously glued book block 8 enters the area of the docking station 24. The feeding of the attachment sheet 25 for and attaching to the book block 8 is in the FIGS. 7a to 7d shown in more detail. These each show a schematic sectional view of the docking station 24 for the attachment sheet 25 and cooperating with the docking station 24 clamping device 5, shown in the direction of arrow VII in Fig. 1 ,

The docking station 24 has a to the withdrawal roller 27, the feed roller 28 and the distribution rollers 29 circulating conveyor belt 63, with a horizontal, a vertical and an obliquely upwardly extending strand 64, 65, 66. In addition, the docking station 24 has three further, driven and each circulating rollers 67 circumferential bands 68, 69, 70 on ( Fig. 7a, 7b ).

Two deflection rollers 67 of the belt 68 are arranged above the withdrawal roller 27 and the feed roller 28 of the application station 24, while the third deflection roller 67 is arranged at the level of the distribution rollers 29 and spaced therefrom. Accordingly, the band 68 has a horizontal and a vertical portion 71, 72, which extend substantially parallel to the horizontal and the vertical run 64, 65 of the conveyor belt 63. Between the vertical run 65 of the conveyor belt 63 and the vertical portion 72 of the belt 68, the two other, each about two pulleys 67 circulating belts 69, 70 are arranged and substantially parallel to the vertical strand 65 of the conveyor belt 63 and the vertical portion 72 of Bandes 68 aligned. By maintaining a corresponding distance of the belts 68, 69, 70 with each other and from the conveyor belt 63 is formed between the horizontal run 64 of the conveyor belt 63 and the horizontal portion 71 of the belt 68, a horizontal conveyor region 73 and between the vertical run 65 of the conveyor belt 63 and the roller side Volume 70 and between the vertical region 72 of the belt 68 and the belt 69 in each case a vertical conveying region 74 for the attachment bow 25 (FIG. Fig. 7c ).

Moves the book block 8 promoting clamping device 5 to the docking station 24, 27 successively two attachment sheet 25 are withdrawn from the magazine 26 and transported by cooperation of the conveyor belt 63 and the belt 68 through the horizontal conveyor region 73, where they by means of a In this area, switches 75 arranged on the upper deflection roller 67 of the roller-side belt 70 are divided in such a way onto the two vertical conveying regions 74, which in each conveying region 74 is an attachment sheet 25. This situation is in Fig. 7a shown. In this position, both the inner pliers 16, ie their pliers halves 30, 31, and the outer pliers 15, ie their pliers halves 17,18 closed, so that the book block 8 is fixed in the clamping device 5.

If the clamping device 5 moves with the book block 8 into the region of the application station 24, the movable pliers half 18 and by means of the actuating bolts 32 the inner pliers 16 in the pliers receptacle 14 are moved radially inward by means of the corresponding lifting mechanism. This results between the outer pliers half 30 of the book block 8 continues to clamp inner pliers 16 and the stationary pliers half 17 of the outer pliers 15, a first radial clearance 76 and between the inner pliers half 31 of the pliers 16 and the movable pliers half 18 of the outer pliers 15th a second radial clearance 77. This situation is in Fig. 7b shown.

As in FIG. 7c shown located in the two vertical conveyor regions 74 attachment sheet 25 now laterally spaced to the book block 8 in the radial clearances 76, 77 between the pliers 15 and 16. In this area, a base plate 78 is mounted below the table 12, with their help the attachment sheet 25 are aligned flush with the book block 8.

According to Fig. 7d Then, the movable pliers half 18 is moved together with the inner pliers 16 in the pliers receptacle 14 radially outward so, that both the book block 8 and the attachment sheet 25 are held by two pliers 15 and 16, respectively. In this case, both the fixed and the movable pliers half 17, 18 of the outer pliers 15 on an inwardly projecting projection 79 which presses the lower portion of the attachment sheet 25 to the previously glued page book block 8, so that the book block 8 and the attachment sheet 25 with each other be glued. In addition, roles not shown for pressing the attachment sheet 25 can be arranged on the book block 8 between the base plate 78 and the table 12.

Both at the docking station 24 for the attachment sheet 25 and to the clamping devices 1-6, of which Fig. 8 only the clamping device 6 shows, each a reader 80 is arranged with which identification features of the attachment sheet 25 is determined and compared with previously read identification features of the respective book block 8 to automatically eject the affected book block in a negative result or to trigger a corresponding interaction of the machine operator ,

Alternatively to a single docking station 24 are according to Fig. 9 two landing stations 81, 82 for each attachment sheet 83, 84 arranged. In this case, an unillustrated Seitenleimwerk is mounted in front of each docking station 81, 82 and the intermediate opening table 22 is omitted. Otherwise, the perfect binder 7 is equipped as described above.

During operation, this alternative solution differs in that when driving over the first gluing unit, only one glue lane is applied to the front side of the book block 8, which serves for the subsequent affixing of the front attachment sheet 83 on the book block 8. Similarly, when driving over the second gluing unit, only one gluing track serving to adhere the rear attachment sheet 84 is applied to the rear side of the book block 8.

When the glued on its front book block 8 enters the region of the first docking station 81, both the movable pliers half 18 and the inner pliers 16 are moved in the pliers receptacle 14 radially inward, so that between the outer pliers half 30 of the book block 8 continues to clamp, inner pliers 16 and the stationary pliers half 17 of the outer pliers 15, a first, radial clearance is formed, in which the attachment sheet 83 is inserted. If the book block 8 in the region of the second landing station 82, the movable pliers half 18 is moved in the pliers receptacle 14 inwardly, while the inner pliers 16 maintains its position on the outside of the pliers receptacle 14, ie immediately adjacent to the stationary pliers half 17. This results between the inner pliers half 31 of the book block 8 continues to clamp inner pliers 16 and the movable pliers half 18 of the outer pliers 15, a second radial, down to the base plate also not shown reaching second space in which the second end sheet 84 is inserted ,

After the attachment sheet 25 or alternatively the attachment sheet 83, 84 supplied and glued to the book block 8 side, the book block 8 passes over the glue unit 33, wherein on its back a defined layer of glue is applied. The book block 8 then arrives in the area above the folding station 34, which results in Fig. 5 is illustrated by the clamping device 4. Starting from the Fälzelbahn 46, a Fälzelstreifen 52 is cut to width and with the side knife 48 to the correct length in this station with the cutting blade 50. The Fälzelstreifen 52 is placed on the lifting table 51 and held there by means of a not shown, arranged in the bottom 85 of the lifting table 51 nozzles applied vacuum. As soon as the book block 8 located above is in the correct position, the lifting table 51 is extended upward and presses the Fälzelstreifen 52 to the glued spine of the book block 8. Alternatively, the two pliers 15, 16 are released, so that thereby free expecting book block 8 is either pressed by its weight on the Fälzelstreifen 52 or guided by a corresponding device down. In this case, the provided with the Fälzelstreifen 52 book block 8 must then be taken up again by the two pliers 15, 16.

During further transport, a glue trace is applied by means of the further side gluing unit 35 on both sides of the book block 8 and close to its back, which serve for the lateral bonding of the trimming strip 52 in the subsequent pressing station 36. Comes the edited book block 8, as in Fig. 6 shown by the clamping device 3, in the region of the pressing station 36, drive the two press plates 55 of the lower lifting table 54 to the required book thickness together and press the Fälzelstreifen 52 laterally. At this moment open both the outer pliers 15 and the inner pliers 16 of the clamping device 4 by appropriate actuation of the lifting mechanism or loading of the actuating pin 32, so that from the provided with attachment sheet 25 and 83, 84 and Fälzelstreifen 52 book block 8 formed Book 58 is now held exclusively by the press plates 55.

In the production of a softcover book, a cover 38, which is corrugated with the creasing wheels 62, is delivered to the upper lifting table 53 of the pressing station 36 by the cover feeder 37 via the conveyor belt 61. During the transport of the envelope 38 on the conveyor belt 61, a plurality of glue strips are mounted on the envelope 38 by means of a Leimwerkes not shown, or another Glimwerkes, which serve the later gluing with the attachment sheet 25, and 83, 84 of the book block 8.

If the envelope 38 completely on the upper lift table 53, the two previously located in their lowered position lift tables 53, 54 go up and press the envelope 38 against the back of the book block now located immediately above 8. Thereafter, from the book block. 8 and the envelope 38 formed book 58 also held exclusively by the pressing plates 55.

Both in the production of hardcover as well as softcover books drive both lifting tables 53, 54 with the thus clamped book 58 down. The upper lifting table 53 remains at the level of the conveyor belt 61 of the envelope feeder 37, while the lower lifting table 54, the book 58 further down through the Recess 57 of the upper lifting table 53 pulls through. As soon as the side pressing plates 55 release the book 58, the bottom flap 56, which can be pivoted downwardly, opens and accompanies the book 58 gently around the display 39 (FIG. 2), which has a downward curved surface 86 (FIG. Fig. 6 ). All necessary format settings are carried out dynamically via suitable drive elements. The pressing force is adjustable, for example by means of servomotors. To save length, the envelopes 38 can be skimmed on the conveyor belt 61 on top of each other.

After the display 39, the book 58 is taken over by a conveyor, not shown. The emptied in this way clamping device 3 is thus ready to receive another book block 8.

The transport device 9, i. the table 12 is continuously driven during the adhesive binding, so that the processing of the book blocks 8 during their transport and thus the supply of the attachment sheet 25, 83, 84 to each one in the transport direction 19 forward moving clamping device 1-6. Here, some processing stations 10 may be formed so that they follow the respective book block 8 synchronously over a certain period of time. This applies, for example, to the docking station 24, 81, 82 for the attachment sheets 25, 83, 84, whereby the relative speed between the book block 8 and the supplied auxiliary sheet 25, 83, 84 in the transport direction 19 is advantageously equal to or at least approximately zero.

Alternatively, the drive can also be carried out stepwise or alternately, so that at least a part of the processing steps is carried out when the transport device 9 is stationary, ie stationary clamping devices 1-6 and book block 8. In this case, the steps of feeding the book block 8, intermediate opening, application of attachment sheet 25 or 83. 84, Fälzelstreifen 52 and envelope 38 and discharge of the book 58 are performed at a standstill, while the steps back processing and gluing run during the transport of the book block 8 , In this case, the transport device 9 is moved stepwise in the transport direction 19, whereby the clamping devices 1 to 6 also gradually to the individual Processing stations 10 are performed. Depending on requirements, the pliers 15, 16 can be opened or closed and the book blocks 8 are accordingly released or clamped. The gluing units 23, 33, 35 and optionally further gluing units are arranged movably under the table 12 in a horizontal plane and are moved via a control cam (not shown) so that they can follow the chord of the book block 8 accommodated in the clamping devices 1 to 6, whereby a uniform gluing is ensured.

When perfect binder 7 all format settings for the clamping devices 1 to 6 and the processing stations 10 can be done dynamically and intermittently, so that at the same book blocks with different formats and thicknesses can be edited. A thick, large book can therefore be followed by a thin, small book, or vice versa. The perfect binder 7 can thus also be used for the production of individual books (edition 1), i. in each clamping device 1 to 6 is another book block 8. Since the perfect binder 7 all required processing stations 10 are arranged, a book block 8 for producing a hardcover book intermittently followed by a book block 8 for producing a softcover book.

The perfect binder 7 has an in Fig. 1 indicated controller 87, which can process the book data from various sources and connected in a manner not shown with measuring and control elements of both the transport device 9 and the processing stations 10. Such book data is, for example, the book ID, order ID, raw book height, raw book width, and book thickness. In addition, the envelope height, the envelope width, the center offset of the envelope (position reference back to cover edge) and the envelope thickness are used. This data can be manually entered as an order in the controller 87 or transmitted from a corresponding detection device to the controller 87. If the perfect binder 7 is arranged in conjunction with a control-compatible system, it receives the necessary book data, for example, from a higher-level control or from the control of a machine in the composite. Finally, the book data can also be with the book block 8 or the envelope 38 transmitted detected with a arranged in perfect binder 7 reader and passed to the controller 87. However, book information can also be transmitted via a database entry, for example from a higher-level control, for example when a corresponding identification is read on the book block 8 or on the envelope 38.

Of course, depending on the actual working conditions, a table 12 with more or less than six pliers receptacles 14 and thus clamping devices can be used. Likewise, not all existing clamping devices must be used in adhesive bonding.

With such an adhesive binder 7, also bound-bound brochures (softcover) can be produced, to which initially also the back of a supplied book block 8 edited, then glued and provided with a supplied from a cover feeder 37 envelope 38. The application stations 24, 81, 82 for the attachment sheet 25, 83, 84 and the Fälzelstation 34 are not needed. The gluing unit 33 for the back glue is then advantageously located in front of the envelope 38 pressing accurately to the book block 8 pressing station 36, which can be used in the hardcover production for pressing the Fälzelstreifens 52. In addition, the feed path of Umschlaganlegers 37 should be long enough so that the correct envelope 38 for each book block 8 can be clocked synchronously.

In general, the perfect binder 7 also allows several gluing units or glue injection devices at different positions, so that the type of gluing can be changed in cycles. This makes it possible to produce a hardcover book and a softcover book or vice versa in quick succession. Of course, the perfect binder 7 can also be configured as a pure softcover machine or as a pure hardcover machine.

In a second embodiment of the adhesive binder 7 'according to the invention, its transport device 9' has a closed, oval circulation path 13 '. The in Fig. 10 from the front shown perfect binder 7 'has analogous to the first Embodiment trained processing stations 10 ', ie a feeder 20' for the book blocks 8 ', a back processing device 21', a Seitenleimwerk 23 ', a landing station 24' for two individual attachment sheet 25 ', another Glue 33', a Fälzelstation 34 'and a with a press station and a display combined, the supply of envelopes 38 'serving envelope 37', of which, however, only the latter is visible. The clamping device 6 'is located in the region of an intermediate opening table 22', where the book block 8 'can be shaken, for example.

Like the transport device 9 of the first embodiment, the transport device 9 'is also driven continuously during adhesive bonding, i. the processing of the book blocks 8 'takes place during their transport. Accordingly, the attachment sheet 25 'are each a in the transport direction 19' forward moving clamping device 1 'to 6' supplied. Again, some processing stations 10 ', such as the docking station 24' for the attachment sheet 25 ', be formed so that they follow the respective book block 8' synchronously over a certain period of time. Alternatively, as in the first exemplary embodiment, the drive can take place in a stepwise or alternating manner so that at least part of the processing steps are carried out when the transport device 9 'is stationary, ie. stationary clamping devices 1'-6 'and book block 8' is performed. The individual work steps for adhesive bonding proceed essentially analogously to the first exemplary embodiment.

In contrast to the first embodiment, the adhesive binder 7 'has a tensioning element for the clamping devices 1' to 6 'formed, not shown transport chain and the clamping devices 1' to 6 'each have a guide element 88, with which they are attached to the transport chain , The guide elements 88 each carry four horizontal and four vertical rollers 89, 90 (FIG. Fig. 11a-c ), which intervene in the transport chain. The thus connected to the transport chain clamping devices 1 'to 6' and thus also recorded by these book block 8 'are transported by means of a chain drive, also not shown to the respective processing stations 10'.

Each clamping device 1 'to 6' has a first, attached to the guide member 88 retaining member 91, which consists of two inverted L-shaped side members 92 each having a short and a long leg 93, 94 and the side parts 92 in the lower region of their long legs 94th inside connecting cross member 95 is. In addition, a second holding element 96 is formed, which also consists of two inverted L-shaped side parts 97, each with a short and a long leg 98, 99. A transverse strut 100 connects the side parts 97 with each other over their entire length such that the second holding element 96 is approximately double-T-shaped in plan view.

The respective adjacent short legs 93, 98 of the two holding elements 91, 96 are pivotally connected to each other by means of a respective rotation axis 101, the short leg 93 of the first holding element 91 outside and the short leg 98 of the second holding element 96 is arranged inside. Between the two side parts 92 of the first holding element 91, a third holding element 102, the transverse strut 95 of the first holding element 91 is arranged encompassing over its entire length. From the third holding element 102 are laterally from two projections 103, with which the third holding member 102 is also hinged to the axes of rotation 101. On the inside of the second holding element 96, a plate-shaped, fourth holding element 104 is arranged, which also has two inwardly directed projections 105 and with these also hinged to the axes of rotation 101 is attached. The projections 105 are located within the projections 103 of the third holding element 102.

The clamping devices 1 'to 6' are thus designed as multipart folding pliers, each with an outer and an inner pliers 15 ', 16'. In this case, the outer pliers 15 'formed by the second and the third holding member 96, 102, while the inner pliers 16' from the first and the fourth holding member 91, 104 is made. The holding elements 91, 96, 102, 104 are designed to be movable about the two axes of rotation 101, so that the clamping devices 1 'to 6' correspond to the book blocks 8 ' Receive, clamp, transport and release requirements. For this purpose, the four holding elements 91, 96, 102, 104 of the clamping device 1 'to 6' each have an inwardly projecting surface 106, 107, 108, 109 (FIG. Fig. 12a-d ).

In the second and in the third holding element 96, 102 of the clamping devices 1 'to 6' in each case a pocket-like, the corresponding holding element 96, 102 penetrating recess 110 is formed, which serves the lateral supply of the attachment sheet 25 'in the clamping devices 1' to 6 '.

Corresponding Fig. 10 For receiving a book block 8 ', the clamping device 1', ie both the outer and the inner pliers 15 ', 16', each opened via a control mechanism, not shown, and closed after successful positioning of the book block 8 ', wherein the holding elements 91 , 96, 102, 104 of the pliers 15 ', 16' are pivoted about their axis of rotation 101 accordingly. The opening angle of the folding pliers depends on the book thickness.

In Fig. 12a-d is the supply of two attachment sheet 25 'in accordance with the Fig. 10 in the region of the docking station 24 'located clamping device 5' shown. For this purpose, the attachment sheet 25 'by means of the docking station 24' from above into the vicinity of the pocket-like recesses 110 of the book block 8 'promoting clamping device 5' and not shown feeding means with their fold 111 first spent in the recesses 110, where they first to Pocket bottom 112 fall down and stored there. Already there, the attachment sheet 25 'by means not shown parallel to the book block 8' be anticipated. Subsequently, both the second and the third holding member 96, 102 are pivoted outwardly via the corresponding control mechanism, ie, the outer pliers 15 'is opened, while the inner pliers 16' remains closed and the book block 8 'continues to clamp. By opening the outer pliers 15 'formed below the inner pliers 16', on both sides of the book block 8 ', between this and both the second and the third holding member 96, 102, respectively, a free space 76', 77 ', in the following the respective header sheet 25 'with its fold 111 further down to the base plate 78 'fall, where they are parallel to the book block 8' aligned and adhered by means of the inwardly projecting surfaces 107, 108 of the holding elements 96, 102 successive pressing on the previously side-glued book block 8 'with this , Due to the relatively short path from the pocket bottom 112 to the base plate 78 'results in a relatively low drop height, whereby a perfect fit bonding the attachment sheet 25' can be guaranteed with the book block 8 '. Since the attachment sheet 25 'remain even after bonding with the book block 8' with its upper portion in the pocket-shaped recess 110, they arrive only at the removal of the book block 8 'from the respective clamping device 1' to 6 'completely to the book block 8'. When the outer pliers 15 'are open, the attachment sheets 25' can also be fed directly through the recesses 110 to the book block 8 'and pressed against them.

In an alternative arrangement of the processing stations 10 ', the attachment sheet 25' already before the book block 8 'in the clamping devices 1' to 6 ', ie in the pocket-like recesses 110, introduced and cached there. This can be done, for example, between the display of the bound books and the feeder 20 'of the next book block 8'. With closed pliers 15 'and 16' fall the attachment sheet 25 'while only to the pocket bottom 112 ( Fig. 12a ), where they can already be anticipated.

Instead of attachment sheet 25 'can the book block 8' on the pocket-like recesses 110 of the clamping devices 1 'to 6' and other flat materials, such as CD case bags are supplied.

In a third embodiment clamping devices 1 "to 6" are formed, of which in FIGS. 13 and 14 The clamping devices 1 "to 6" each have a first pliers 113 fastened to or in the transport device, not shown here, designed as a gripping pliers 113. In addition, at the landing station 25 also not shown here, 25 ', 83, 84 a stationary, also designed as a tongs second pliers 114 for the book blocks 8, 8' and above the first pliers 113 and spaced apart attached to this. In this case, both the first and second pliers 113, 114 each have two mutually movable pliers halves 115, 116; 117, 118 on. The pliers halves 117, 118 of the second pliers 114 are each attached by means of a hinge 119 at the landing station for attachment sheet 25, 25 ', 83, 84 and are opened or closed via a control mechanism, not shown. Alternatively, in each case only one pliers half 115, 117 can be designed to be movable relative to the other pliers half 116, 118.

In the operation of an adhesive binder 7, 7 'equipped with the pliers 113, 114, first the book blocks 8, 8' are gripped in a lower region 120 by the clamping devices 1 "to 6", ie by the first pliers 113 and to the processing stations 10, 10 'promoted. If a book block 8, 8 ', as in Fig. 13 shown in the direction indicated by the second pliers 114 landing station for attachment sheet 25, 25 ', 83, 84, so this is detected in an upper portion 121 of the second pliers 114. Thereafter, the first pliers 113 is opened so that on both sides of the book block 8, 8 ', a free space 76, 76', 77, 77 'is formed, in each of which an attachment sheet 25, 25', 83, 84 is introduced to the base plate 78 ( Fig. 14 ). When re-closing the first pliers 113, the attachment sheet 25, 25 ', 83, 84 are pressed in its lower portion 120 to the book block 8, 8' and glued to this. After releasing the second pliers 114, the book block 8, 8 'is free again and is then conveyed to the next processing station 10, 10'.

As an alternative to the exemplary embodiments described, the closed orbit 13, 13 'of the transport device 9, 9' can also be designed as a polygon or as a bulky curve. Of course, the folding pliers of the second embodiment can also be used in a perfect binder 7 with a closed, circular orbit 13.
