Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a book or a block of a book newly wrapped in a cover (
The method of forming, f'old burning and whole pressing of books or blocks of books, in this case in the form of a chain-like product stream,
The grooves are continuously fed to a compaction machine, which machine includes a charging station, a plurality of forming-grooving-compacting stations, and a withdrawal station, and the book is placed in an adjustable predetermined position. The grooving relates to a method of leaving the same product flow in the compaction machine after passing through each station for a period of time.

The invention also relates to a grooving and pressing machine which includes a charging station, a plurality of forming-grooving-clamping stations, a collection station, and a transfer station for transferring books from one station to the next station. and electrically controlled conveyance means for supplying, transferring, and transporting.

[Prior art and its section report] In the book production line used for industrial bookbinding, in the machine, a booklet cover cut to the size is hung on a block of books, and the book block is attached with a cover. The loose pieces of paper and/or endpapers on the inside of the cover are glued to strengthen the bond between the cover and the book blocks. The block of the book wrapped in the cover is at this stage already preformed, in particular rounded, or is still in an unformed state. The book or block of newly bound books emerging from the machine is then passed through one or more clamping stations where full clamping is performed.

That is, the entire area of the book is now compressed until the glue between the cover and the block is completely hardened.

If desired, the block of books may be molded in a separate molding station or in a molding-clamping station. When attaching a hard cover, the book is generally rounded out.

Before, during, or after full pressing, groove stamping and groove burning are carried out, in which the jaws of a heatable press are pressed against the bookbinding cover, and the spine and top and bottom sides of the cover are pressed together. A connection, or groove, is formed.

Various methods and devices have been proposed in the past to enable mechanical forming, grooving, and all pressing to be performed in one production line.

That is, German Patent Publication No. 1.536,502 discloses the following method. In this case, bundles of books or blocks of books, etc., which in any case are supplied in several upright positions, are loaded one after the other at regular time intervals into a plurality of stations arranged in the direction of movement. , and in that time the groove pressing is carried out by increasing pressing pressure from one station to the next, and at the next one or more stations individual or multiple simultaneous total pressing is the same. at the above-mentioned time intervals.

Furthermore, the device disclosed in German Patent Publication No. 1.538,502' is movable horizontally opposite each other and at right angles to the direction of movement of bundled books or blocks of books, etc. and a station provided in the slotting machine formed by the two press jaws, in which the clamping pressure is gradually increased. The two press jaws of this slotting machine carry opposing slotting plates at their lower ends, which are arranged in stepped pairs in a number corresponding to the number of clamping stations provided in the slotting machine. It is located prominently in the

A basic drawback of these known methods and devices is that the books are arranged with the aid of a star feeder and are conveyed in an upright position throughout the device. However, at least while passing through the first station,
Since the glue between the cover and the block has not yet completely set, the joints between the cover and the block are misaligned with each other, thus causing “
There is a risk that the pieces of play paper may be bent or ruined.

A second disadvantage of these known methods and devices is that all the stations are arranged in a straight line in series and, due to their overall length, it is not possible to combine these machines into one production line. This is difficult and at the same time limits production efficiency and capacity. Among other things, since each individual book has to pass through several successive clamping stations, the press jaws have to be opened and closed repeatedly, which firstly results in long wasted times and secondly The relationship between the book block and the cover described above has to change here as well.

German Patent No. 1.207,334 discloses the following bookbinding and pressing machine. That is, separate stations for forming, grooving, and full-pressing are provided on a circular table, which rotates about a vertical axis at regular time intervals like the hands of a clock. Although in this design the books are still carried upright, the main drawbacks of known structures such as those mentioned above are avoided by this rotor method.
That is, while passing through all the work stations, the individual blocks are
p), so that the jaws of the press only have to be opened and closed once. However, the capacity of a machine operating with this rotor-only method cannot be increased above a certain limit, as a result of which the books are delivered via only one collection station run. Also, in order to retrieve the books without defects from the grooving and pressing machine, it is necessary to wait a certain minimum amount of time beyond what is absolutely necessary.

[Means for solving the problem and their operation] It is therefore an object of the invention to provide a highly efficient method and device of the type mentioned at the outset, in which the entire pressing time is reduced. The advantage of the rotor method, in which the groove pressing plate and the press jaws remain closed throughout, is maintained, and there is no shortage of pressing time per book. Furthermore, the method and apparatus are configured to minimize as much as possible the risk of a relative misalignment between the book block and the cover.

This problem is solved by a method of the type described in the invention, in which the product stream consisting of books or blocks of books housed in covers and continuously fed into a machine is in the input station into n rows of parallel tributaries, and said n rows of tributaries are continuously fed into the same n rows of parallel forming-grooving-clamping stations; After passing through, it reaches a collection station.

The method according to the invention is therefore characterized in that instead of the rotor method described above, and instead of the method with series linearly arranged shaping-grooving-clamping stations described above, another method is used. , this method corresponds to an electrical parallel circuit, ie a plurality of forming-grooving-clamping stations are arranged adjacent to each other in parallel.

This new method according to the invention divides the product-fed stream into multiple tributaries that can work in parallel and thus remove finished products from collection stations, which traditionally limited capacity. This will solve the bottleneck in transporting.

The advantage of the rotor method is that the individual book remains in a single forming-grooving-clamping station during the entire pressing period, and the press jaws are opened and closed only once; This advantage is directly inherited by the method. The capacity of the method according to the invention is higher than that of the known methods, and the pressing time per book is reduced without compromising the quality of the books processed.

An embodiment of the method according to the invention provides that the tributaries fed to the collection station are either combined into a single product stream in said collection station and exit the machine, or are relocated to a different tributary. the tributaries supplied to the collection station are led out from the collection station in the form of parallel tributaries in the upper row, and the book or the book wrapped in the cover is It is characterized by the fact that the blocks are individually carried in a lying position, moved, and moved forward.

The last-mentioned feature of the embodiment is particularly favorable, since when the book is moved in a lying position, no means of stop-rotation and raising are required, so that the transport means used are simply Not only that, but also, in particular, any negative influence on the rounding of the book is eliminated.

In a grooving-clamping machine of the initially described type, the problem is solved according to the invention by means of n rows of forming-grooving-clamping stations arranged adjacent and parallel to each other, n being an integer. resolved.

In one embodiment according to the invention, molding-grooving-
A clamping station is fixedly connected to the frame of the machine.

A feature of one embodiment of the machine according to the invention is that the above-mentioned molding-
Each groove-pressing station includes a horizontally mounted pressing table for pressing grooves, a pair of vertically movable groove pushing plates, and a horizontally movable molding plunger. at least one molded web forming the backrest of the book spine arranged in the position, and an endless conveyor belt, the running surface of which wraps around the above-mentioned pressing table, the running surface of which runs above the pressing table. The invention also includes a device that is adapted to abut against the surface of the book and to form a support portion for the book.

In this embodiment of the machine according to the invention, therefore, the six branches of each tributary are laid flat on the cover of the binding case, and without having their backs vertical as before, the molded- Grooving - fed to the clamping station. This makes the design of the clamping station very simple, economical and highly efficient. The lower part of the full press can be made like a horizontally mounted fixed press table, so that only one vertically movable press jaw is required. However, this press table can also be moved vertically, halving the vertical stroke of the press jaws compared to an embodiment with a fixed press table. Allowing the press table and the press jaws to move towards each other, the pressure distribution during the press is good, and the grooves, roundness and spine of the book are formed and compressed particularly precisely, and at the same time a favorable condition is processed quietly.

According to the invention, three tubes are inserted into each molding station from the charging station.
The method and equipment carried to the grooving-clamping station are:
For this purpose, an endless conveying belt simply runs around the press table, so that its running surface wraps around the press table, so that the upper running surface touches the top surface of the press table and at the same time It is particularly advantageous if it forms a support for the book inside.

Preferably, said loading station comprises conveyor means operating in the direction of entry of the books and conveyor means operating at right angles to said direction of entry and serving to convey the books to a forming-grooving-clamping station. , while said retrieving station is orthogonal to the conveying direction of said conveying means, said conveying means serving to retrieve books from said forming-grooving-clamping station and acting in the conveying direction of said conveying means; and a conveying means acting in the direction of carrying out the book.

Preferably, the driving of all conveying means is reversible with respect to the conveying direction.

Conveying belts or feed rollers are conveniently used as conveying means.

All forming-grooving-clamping stations are controlled simultaneously, individually or in combination, by known mechanical, electrical and electronic means, thereby opening, closing, raising and lowering the press jaws and press table. , actuation of the forming web and forming plunger, and driving of the conveying means.

The desired or required capacity of this machine can be adjusted to 3 by selecting the number of forming-grooving-clamping stations accordingly.
No reduction in book clamping time (achieved or added) by installing an n++ forming-groove-clamping station connected in parallel to the machine where it is used. can be increased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The groove-clamping machine according to the invention shown in FIG. 1 consists of three main parts: a charging station 30 (lower part of the figure); forming-grooving-pressing stations 13°...13rL, and a recovery station 40 (upper part of the figure).

Book block G newly wrapped in book 6 or cover 6a
b (see FIG. 3) are continuously fed to the charging station 30 in the form of a chain-shaped product stream 20 with the book spines 6c in front. A chain-like product stream here refers to a stream of books or blocks of books that are arranged consecutively in a row, but at a distance from each other.

Three of these product streams 20 are conveyed in the direction of flow indicated by arrows 20, for example with the aid of a conveyor belt.

With the aid of known, but not shown in the figures, fully automatic electronic control means, the drive means of the conveying means are controlled;
Each time a book 6 is held in the loading station 30 in the order shown in FIG. It is supplied to the tightening stations 131...13rL. In this way, the product flow 20 is arranged in n columns, 5 in the figure.
The n-row tributaries are continuously supplied to the corresponding n-row forming-grooving-clamping stations 131...13rL. In the stations 131...13a, the book 6 stops and remains there for a predetermined predetermined time for each tributary, during which forming, grooving and full clamping take place.

Tributary streams 20 leaving forming-grooving-clamping stations 131...134. ...20 rL is then supplied to the collection station 4o, and by means of conveyance provided here, 3
Books B are conveyed individually to the right, to the left, or straight in another direction as desired. As a result, tributaries 201...2
0n are organized in a collection station 4o in a single product stream 21 leaving the machine to the right in the diagram.
Or it goes out in the left direction 22, or alternatively it reorganizes into tributaries 21, 22, 23. However, all tributaries20. ...20fi can also be led out from the recovery station 4° in the same n rows of parallel tributaries 23 as before. The drive of the conveying means is designed in such a way that the direction of conveyance can be reversed in each case. Due to these various output functions, the machine according to the invention is free to organize its own book production line on its own or to be added to other assemblies.

Branch 20. . . . a 2-on book 6 is subjected to forming-grooving-clamping suction 13. ...13n is supplied one by one at regular time intervals controlled by the sensor IO. The stations 13 each have a book 6
a horizontally arranged press table l and vertically movable press jaws 2 for the total compaction of an endless conveyor belt running surface 7a, 7b guided via driving and guiding rollers or rolls 7C. This belt wraps around the press table l, the upper running surface 7a resting on the upper surface of the press table l and at the same time forms a support for the book B. As soon as the book B reaches the predetermined position in the forming-grooving-clamping station 13, the drive of the conveyor belt 7 is stopped fully automatically. After the press jaw 2 is lowered and a predetermined residence time has elapsed,
Raised for the first time. The drive of the conveyor belt 7 is then reactivated and the fully pressed books are transferred to the laterally moving conveyor belt of the collection station 40 and from there via another conveying means of the collection station 40. , into one of the product tributaries 21, 22, 23.

One of the important features of the invention is that the conveyor belt 7
Even during its rest period, it remains in the pressing position in the forming-grooving-pressing station (Figure 3).
.

Molded plunger 4 movable horizontally during full compaction
remains in the working position shown in FIG.

A shaping web 5 is provided as a presser for the spine 6c of the book 6 placed in the lying position, so that the desired shaping, in particular the roundness of the book, takes place. The surface of the molded web 5 that rests against the book spine 6c is flat or curved, depending on the book molding plan.

Along with this, each forming-grooving-clamping station 13.
...13rL is equipped with a pair of vertically movable groove pressing plates 3 for groove pressing. These grooved plates are heated by known means so that, under the influence of pressure and heat, the grooves 11 form the joint between the cover and spine 6c of the case 6a.

As is clear from the foregoing description, since each individual book passes through only one forming-grooving-clamping station, the press jaws only need to be raised and lowered once each time the book is completed. Furthermore, since the books are carried slowly in a lying position, there is no fear that the blocks eb of the books in the case 6a will shift when the books are carried from one station to the next. As a result, there is no occurrence of defective products due to defects in play sheets, which is the case with conventional devices and methods in which books are basically transported with their spines upright.

A further advantage of the device and method according to the invention stems from the fact that books can be removed from the machine at several outlets. As a result, if an accident occurs in the next process, for example, in the direction of the product flow 22,
An emergency exit can be provided. A further possibility of this delivery mechanism is to deliver the books parallel to the direction of the tributary stream 23, for example towards an inclined roller conveyor.
