Description

The invention relates to a book cover feeder for feeding book covers to a production unit of a book production line according to the preamble of claim 1 and a method according to claim 11 for applying a stack with book covers on such a book cover feeder and a book production line according to claim 15 with such a book cover feeder.

Known book production lines intermittently add a book block and a book cover to a book. The book cover refers in a general sense to that part of the book that fits around the book block and protects it, regardless of the construction as a cover tape or tape with attached lids.

A so-called cover is usually made of two fixed lids made of cardboard, which are held together by a Bezugsnutzen. On this utility material with a little distance to the cardboard on each side a so-called Schrenz attached as a back insert. The cover material is mostly paper, but can also consist of other materials such as linen or leather. Between the three parts, i. The two lids and the Schrenz is thus formed a kind of hinge for the finished book.

Initially, the book blocks and book covers are usually made in separate machines. In known book production lines the book block goes through at the beginning separately from the associated book cover processing stations such as rounds, pressing, Rückenbeleimen, funds, etc. The so-called wedding of book block and book cover then takes place in the Einhängemaschine, the Einhängemaschine is understood as a production unit of the book production line.

From the DE 94 03 531 U1 a book cover feeder is known which serves book covers to a hanger. The substantially horizontally lying book covers are piled up in a book cover magazine so that a respective bottom book cover of the stack just touches an effective surface conveying conveyor belt. In cyclic drive of such a belt conveyor, the respective bottom book cover is removed from the stack and transported out through a passage gap from the book cover magazine. In the case of hard ceiling processing, this known book cover magazine can be operated with an additional integrated slide support.

More book cover magazines are out DE 36 14 216 C2 and DE 202 02 513 U1 known.

Known book cover magazines represent continuations of a respective magazine shaft. The stocking of the book covers to be processed is increased by such a book cover magazine. The book covers are preferably scaled on the book cover magazine placed. For correct positioning of the book covers, the book cover magazine is provided with guides at the front, at the back and at the sides on the right and left. Of this, lateral boundary parts of a book cover band align the book covers centrally to the Schrenz. For this purpose, a right rear guide of the magazine shaft is mechanically connected to a rear side guide of the ceiling tape magazine. The adjustment of this side guide or this lateral ceiling stop is done jointly by means of an adjustment motor. A level control in the magazine shaft controls the drive motor of the feed belt and ensures automatic filling of the magazine shaft with book covers.

Arrived in the Einhängemaschine, the book block, as for example EP 1 780 037 known, astride sitting on a saddle plate vertically past a side gluing. There are two intentions of the book block glued. About supply rails and by means of a slider, the book cover is fed horizontally above the Seitenbeleimung and positioned over the incoming book block. Then takes over, such as from EP 1 780 038 Known to be an applicator the book cover and this fits together with the book block.

In known book production lines it is assumed that the books are processed as a medium or large edition. As a result, just as many book covers are available for a series of several book blocks. It is not necessary to pay attention to an order because one book is composed of one edition, just like the other.

In the production of personalized books, such as photo books, both the book block and the book cover is unique. When producing personalized books or small and very small print runs in general, a clear identification of the book cover and the book block is a crucial criterion. For smooth operation in the machine either the book cover or the book block must take over a control function. One part therefore specifies to the book production line which other part is to be married to the one part.

This results in the task, a targeted and flexible integration of one of the parts of the book of a small or very small edition in a book production line and to allow the most economical and secure allocation of the parts to be married.

Furthermore, the object is to provide a book cover investor of the type mentioned, which stores several blanket formats at the same time, so that the book covers different format can be economically processed one after the other. Switching to the different formats should, if possible, be automatic.

The object is achieved by a book cover feeder for feeding book covers to a production unit of a book production line with the characterizing features of claim 1 and a method according to claim 11 for applying a stack consisting of the book covers on such book cover and a book production line according to claim 15 with the book cover feeder. Advantageous embodiments are specified in respective subclaims.

The book cover feeder is integrated into a book production line, wherein the book finishing line side of a book cover stream has a leader and a drive side. The book covers can be conveyed as a book cover stream in a production direction through the book cover feeder. The book cover feeder has a feeder, a ceiling magazine and a singulator. On the feeder n book covers are individually, scaled and / or placed as a stack.

The book covers of a pile are book covers of a format. The ceiling magazine has a stacking shaft in which the book covers of a scaly stream of books can be collected prior to their separation. The singling device isolated according to the known principle of a separating step each bottom book cover from the stack and promotes them simultaneously in the production direction. In principle, a wide variety of known separation principles can be used. The feeder, the ceiling magazine and the singler are integral or consecutive.

Depending on the design, compact designs can be realized as well as designs with more buffering options for individual book covers or entire stacks.

The feed device has on the driver's side and / or the drive side on a subdivided in any number of segments side guide device. The segments are arranged one behind the other in the direction of production.

Such a ceiling feeder allows adaptation of the feeder depending on the format of the stack applied to one of the segments. The ceiling feeder can be automated.

According to an advantageous embodiment of the book cover feeder, at least one first segment of the side guide device in the production direction is designed to be displaceable transversely to the production direction. If the feed device is designed to be correspondingly long, a plurality of segments which can be adjusted transversely to the direction of production make it possible to stock a plurality of detected stacks.

In this case, automation means that the stack automatically specifies a shift of the segment that corresponds to its format.

Seen in the direction of production rear segments of other advantageous embodiments can be moved pneumatically to the rear.

Since the aligned book covers are fed very slowly on the book cover magazine is a lateral displacement of the book covers excluded.

When large runs are processed, extended segments are retracted so that the segments form a closed plane. This is necessary because, due to a one-man operation and a high processing speed, the entire tape length is used for laying the book covers of a format.

According to a further advantageous embodiment of the book cover feeder, at least one last segment of the side guide device seen in the direction of production is displaceable transversely to the production direction together with a corresponding lateral guide element of the stacking shaft. In a book cover feeder formed in this way, according to a further advantageous embodiment, the segments and the side guide element are mechanically connected to one another via a longitudinal base. Such book cover investors are particularly cost-effective and space-saving design.

According to a further advantageous embodiment of the book cover feeder, one or more of the segments is in each case rotatable in the longitudinal base by means of a mounted spindle transversely to the direction of production against the longitudinal base displaced. The spindle can be driven by means of a drive via a spindle gear.

According to a further advantageous embodiment of the book cover feeder, one or more of the segments is displaceable transversely to the production direction by means of a lifting cylinder.

According to a further advantageous embodiment of the book cover feeder, the spindle and the lifting cylinder are coupled together in series.

In a book cover feeder according to one of the advantageous embodiments with at least one slidable transversely to the production direction segment, this segment is aligned parallel to the production direction and by means of guide elements, in particular by means of a paired telescopic guide, the alignment parallel to the direction of production, transversely displaceable to the production direction.

A ceiling feed can be designed individually in individual embodiments by means of individual strips, each with a separate drive. Adjustment devices and guides of the segments of further advantageous embodiments are mounted stationary.

A book cover feeder according to a further advantageous embodiment has at least one sensor for recognizing and reading an identifier of any book cover or stack. A first such sensor is arranged on the end of the feed device facing away from the stacking shaft in the production direction.

In a book cover feeder in accordance with a further advantageous embodiment, a signal generator is subsequently arranged on the feeder or on the end of the feeder device facing the stacking shaft in the direction of production. The signal generator is suitable for detecting a gap between placed book covers.

The FIGS. 1 to 4 show a book cover feeder 1 for feeding n book covers 7.1 - 7.n equipped with a leader page 2 and a drive side 9 production unit 5 a book production line 6 according to FIG. 7 , On the drive side 9 drives are usually arranged, while on the driver's side 2, the operation is done by a machine operator. The book covers 7.1 - 7.n can be conveyed in a production direction P through the book production line 6 and the book cover feeder 1. In the Fig. 7 illustrated, last production unit of the book production line 6 is a Einhängemaschine.

The known book production line 6 initially conveys in a book block conveying direction F book block 3 without book covers by several production units. Preferably located in each of the production units 5 book block 3 without book covers or book block 4 with book covers 7.1 - 7.n. Book cover 7.1 - 7.n are fed in the production direction P parallel to the conveying direction F. The suspension machine has a circulation conveyor 14 with saddle plates 8 for transporting book blocks 3, 4. The saddle plates 8 promote the not yet provided with a book cover 7.1 - 7.n book block 3 in a direction of unification E in an area below a currently supplied book cover 7.n-1, 7.n. By further moving the circulating conveyor 14 or the saddle plate 8 located below the currently supplied book cover 7.n-1, 7.n in the direction of unification, it lifts on this saddle plate 8 located book block 3 the supplied book cover 7.n-1. An unrepresented operator takes over the book cover 7.n-1 and adds these accurately with the book block 3, so that a book block 4 is created with book cover.

The book cover feeder 1 according to FIGS. 1 to 4 has in the direction of production P successively or each other the book covers 7.1 to 7.n passing a feeder 10, a ceiling magazine 20 and a separating device 23 on. The book covers 7.1 - 7.n are shingled on the feeder 10 in separate stacks 7 different orders DS1 to DS7 launched.

In the FIGS. 1 to 3 There are three orders DS1 to DS3 or DS4 to DS6 on the illustrated book cover feeder 1. The formats of the book covers 7.1 - 7.n each of these orders DS1 to DS6 are equal within an order. Such orders are to be understood as short runs. In the extreme case, a stack 7 consists of only one book cover 7.1. Then would be spoken of a small edition.

The ceiling magazine 20 has a stacking shaft 21 with side guide elements 22 and downstream of or below the stacking shaft 21 a separating device 23. The separating device 23 ensures removal of a single bottom book cover 7.1 - 7.n from the detected stack 7.

The existing from the book covers 7.1 to 7.n stack 7 is referred to as detected stack 7, because all book cover information has been detected and the book cover information with an identifier per detected stack 7 in an internal control device 24 and / or an external control device 130 are retrievable. In this case, the internal and external control devices 24, 130 communicate with one another via data transmission S. For detecting and reading the respective identifier, a sensor 40 is provided at the upstream end of the feeder 10 as a detection device.

The feeder 10 has on the drive side 9 a subdivided into two segments 11, 12 side guide device 15. The segments 11, 12 are arranged one behind the other in the production direction P and designed to be displaceable transversely to the direction of production P.

In addition, a parallel to the production direction P aligned longitudinal base 16 is arranged on the drive side 9. The longitudinal base 16 is mechanically connected to one of the side guide elements 22 on the drive side 9 of the stacking shaft 21. The lateral guide element 22 and the longitudinal base 16 are displaceable by means of a motor 16.3 transversely to the direction of production P. About one in Fig. 2 illustrated, formed as a spindle guide 16.2 and another spindle 16.1 causes the motor 16.3 a displacement of the longitudinal base 16 to a stacking dimension of a first order DS1. The segments 11, 12 arranged on the longitudinal base 16 travel along with the longitudinal base 16 and can be adjusted in accordance with a second order DS2 and a third order DS3.

The first segment 11 is displaceable by means of a rotatably mounted in the longitudinal base 16 spindle 30 transversely to the direction of production P against the longitudinal base 16 ( Fig. 4 ). The second segment 12 is displaceable by means of a lifting cylinder 36 transversely to the production direction P against the longitudinal base 16 ( Fig. 3 ).

The Figures 5A . 5B . 5C . 6A and 6B The feeder 30 is associated with the first segment 11, the drive 10 has a drive 32 with a drive shaft 34, wherein the spindle 30 is connected via a spindle gear 33 to the drive 32 in its installed position as an enlarged view in a section of the feeder 32. The drive shaft 34 engages at its free end with a first bevel gear 33.1 in a second bevel gear 33.2 of the spindle gear 33 so that it can come to a rotation about an axis transverse to the drive 32 axis. The second bevel gear 33. 2 is formed as one end of the spindle 30. According to FIG. 5C the spindle 30 is the only adjusting element.

The first segment 11 is in accordance with Figures 5A . 5B . 6A and 6B additionally displaceable transversely to the production direction P by means of a lifting cylinder 36. The spindle 30 and the lifting cylinder 36 are coupled via a mounting plate 18 in series. The spindle 30 can rotate by rotation the mounting plate 18 relative to the longitudinal base 16. The arranged below the spindle 30 lifting cylinder 36 adjusts the first segment 11 relative to the mounting plate 18 (see, in particular Fig. 5B . 6A and 6B ).

The FIG. 6A shows a maximum extended segment 11. In this case, the lifting cylinder 36 is fully extended as Vorstellelement. The spindle 30 must be completely screwed in to reach this position of the segment 11 to the drive. The FIG. 6B shows the other extreme of a maximum retracted segment 11.

The transversely to the direction of production P displaceable first segment 11 remains aligned parallel to the production direction P. This is ensured by laterally arranged to the spindle 30 guide elements 35.1, 35.2. In the guide elements 35.1, 35.2 is a paired telescopic guide 35. In each telescopic guide 35, a rod 37 is centrally arranged. The rod 37 is bolted to the front side against the first segment 11. The rod 37 is slidable in the telescopic guide 35 in the axial direction. The displacement is made by the cylinder 36.

The book cover feeder 1 after the FIGS. 1 to 4 has at least one sensor 40 for detecting and reading an identifier of any book cover 7.1 - 7.n or the stack 7 on. The sensor 40 is arranged on the end of the feed device 10 facing away from the stacking shaft 21 in the production direction P. Subsequent to or at the end of the feeder 10 facing the stacking shaft 21 in the direction of production P, a signal transmitter 41 designed as a light barrier is provided for detecting a gap L between mounted book covers 7.n; 7.1 arranged ( Fig. 2 . 3 ).

About the feeder 10 as a sensor 40, a bar code reader is mounted, which identifies the launched stack 7 automatically based on its identifier and matches the specifications of the external control device 130.

The data of the stacks 7 are previously generated by a detection and automatically transferred to the book line. The detection is not the subject of the present invention.

Compliance with the order of the book covers 7.1 to 7.n of the stack 7 is automatically checked after the transfer to the feeder 10 by means of the bar code reader and matched with the existing data. By the procedure that is accessed on existing data, it is possible that in a pending format change the first segment 11 is already preset.

The buffering of the book cover feeder preferably comprises several hundred book covers and thus creates the necessary production lead for book block production.

The new sequential split and adjustable for the format book cover feeder 1 allows the processing of several different stacks 7 in the book production line 6. By this fact, it is possible that the external control device 130, for example, together with the data transmission S connected internal control device 24 of the book production line 6, equipped with the block feeder with a bar code reader the adjustment and control of the bar coded book block 3 takes over. Of course, this may be done without an internal controller 24, i. can be realized only with the external control device 130.

Depending on the equipment of the machine, there are 8 or 14 book blocks in the processing stations instead of the already mentioned 4 book blocks. This fact makes it imperative that the correct order of book block and book cover is in the machine. In a mismatch of book block and book cover the corresponding book block is ejected before entering the book production line. Thus, in the book production line, only book blocks corresponding to the order and the order according to the request of the external controller 130 to the book covers in the ceiling feeder are provided.

Due to this automated procedure and data transmission a mismatch is almost impossible. If one of them nevertheless occurs, a production interruption is only made after several match attempts. The cross check of the book cover takes place in the ceiling feed. A barcode reader checks the data of the book cover with the data of the waiting book block two bars before merging the book block and book cover. In the case of Missmatch the book production line stops in a controlled manner, d. H. Processing steps are completed and the ceiling transport is stopped to remove the wrong book cover. Of the four books in the hanging machine, three are completed and taken out of the book production line. The fourth book block without book cover does not undergo side gluing and is taken from the book display.

Since the removed book block is not defective, but only has no book cover, it can be fed back later processing with the appropriate book cover.
