EP2921315B1 - Device for removing at least one book cover from a flow of book covers on a book production line - Google Patents

Description

The invention relates to a book production line with a device for removing at least one book cover from a moving on the book production line flow of book covers according to the preamble of claim 1.

Known book production lines intermittently add a book block and a book cover one after the other. Initially, the book blocks and book covers are usually made in separate machines. In well-known book production lines, for example DE19729529 A1 , the book block first passes through separately from the associated book cover processing stations for rounding, squeezing, back glues, funds etc. The book cover usually passes through a Deckenausbiegeeinrichtung before it comes in a downstream Einhängemaschine for so-called wedding, ie to a combination of book cover and book block.

Such conventional book production lines are based on the production of books in medium or large editions. 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 within one edition one book is composed like the other.

In the production of personalized books in small print, for example, photo books, both the book block and the book cover is unique. The smallest edition therefore requires a clear identification of the book cover and the book block. This already indicates the DE102008034065 A1 which discloses the preamble of claim 1. For the smooth procedure of short runs in a conventional book production, of which, for example, in a range of throughputs 3600 hardcover books per hour speaks, either the book cover or the book block must take over a control function. A part of the later book therefore specifies the book production line, with which other part of the later book it is to be united. The problem of a targeted and flexible incorporation of one of the parts of the book of a small edition in a book production line and a secure allocation of the parts to be married takes the CH 00759/10 at. There is proposed to create task pile consisting of book covers of known composition. Their ceiling information is made available to the book production line under a single identifier for the job stack.

In the operation of conventional book production lines using the prior art described, it turns out that in some cases a removal of individual book covers and / or book blocks is required, which is not realized in conventional construction of book production lines. Such cases are given, for example, when the book covers and book blocks have different lengths to cover in the book production line. For example, due to the process, there are 12 book blocks in processing stations, while only 3 book covers already rest. So it can happen that the matching book blocks are not yet available for the book covers in the book production line. There are also other irregularities conceivable, for example, a book part is damaged in a processing station or quality defects are found in other ways. Then it may make sense to remove a part of the book before it comes to the wedding.

In the event that in the ascending or descending order book blocks in the processing chain is missing, this blank book block is assigned a blank cycle and ejected in the appropriate place, the assigned blanket.

It results in the task of designing a removal of individual book covers from the current flow of a conventional book production line. The removal should not interfere with the flow as possible. Also, if possible no additional space is needed. Another guideline is a quick intervention not to complicate the book production line, ie the conveyor lines should remain as accessible as possible.

The object is achieved by a book production line with a device according to the features of the characterizing part of claim 1.

The device has a tray, which is formed to receive the at least one book cover from the flow of the book covers in the flow in retractable.

According to an advantageous embodiment of the device, the tray is substantially rectangular in plan view, formed with an upstream free end and a downstream attachment end. In an area of its attachment end, the tray is hinged in the book production line. The tray is adapted for retraction between an upper rest position without contact to the flow of the book covers and a lowered catch position with contact to the flow of the book covers convertible.

According to a further embodiment of the device, the tray consists essentially of a middle support and adjacent supporting angles, wherein the center support and the support bracket are aligned parallel to the main transport direction of the book covers.

According to a further embodiment of the device, the tray for articulated mounting in the region of its attachment end has a rotational axis formed perpendicular to the main transport direction.

According to a further embodiment of the device, the tray is connected at its attachment end with bearing shoes linearly and parallel to the main transport direction slidably connected to the book production line. The shelf is formed particularly advantageous with bearing shoes suspended in format-dependent adjustable baffles the book production line.

According to a further embodiment of the device, the tray is formed with its free end facing the flow of the book covers on a flap device can be placed.

These configurations of the tray have advantages because the filing can be used and removed quickly and without much installation effort and therefore does not stand in the way of the format changes of moving in the book production line book covers or can join them.

According to a further embodiment of the device, the flap device has at least one in a parallel to the main transport direction and perpendicular to the tray aligned plane pivotally mounted cylinder having a free end which faces the free end of the tray. Such an actuator is particularly suitable for rapid adjustability of the tray.

The removal of at least one book cover is used in the production of books in a book production line, in particular in the production of small runs of books, and has a main transport direction of the book covers. Books made with the book production line consist at least of a book block and a solid book cover protecting the book block. The book block and book cover are transported either parallel to each other from the same direction or from different directions to the wedding.

Initially, identifiers of both the book blocks and the book covers are identified. Subsequently, the removal of the at least one book cover in response to an occurring in a machine control evaluation of the previously made identification.

After feeding a stack consisting of book covers as well as a number of book blocks in the book production line finds an identification of the plate at least one book cover in the flow of the book production line and a forwarding of the identified plate to the machine control instead. The machine control assigns to the supplied stack due to the characteristic of this book cover a stored in the machine control record on the order of book covers in this stack. Either this assignment happens automatically or the record is assigned by an operator to the supplied stack. In this case, the record is merely activated, for example, by an action of an operator or the operator initiates the data transfer by means of a corresponding operation. Due to the characteristics of the supplied book block, an order of these book blocks is determined in the machine control and compared with the record to the order of the book covers. As a result of this comparison, in at least one book block absent the book cover order, the machine controller causes the removal of at least one book cover corresponding to the at least one missing book block.

This makes it possible to auszuschleusen one or more blankets cost-effective and trouble-free from the processing and cache. At the end of a work order, removed book covers can be returned to a ceiling magazine exactly in this order. The data or the order of the discharged ceilings are known to the machine control and can be taken over.

Advantageously, the removal of the at least one book cover after a Deckenausbiegen.

Alternatively, the removal of one of the book covers takes place during a fall out of a processing device of the book production line, in particular from a Deckenausbiegeeinrichtung. In this case, a tray is retracted into a flight curve of the book covers to catch the at least one book cover.

In a book production line 6 book block 61 are combined with corresponding book covers 2 to books. The Fig. 1 shows a section of a book production line 6, with a Deckenausbiegeeinrichtung 3, in which the book covers 2 are bent out so that they get their flatness after the union with the book block 61 and after drying. Upstream of Deckenausbiegeeinrichtung 3 is a ceiling magazine 7 for receiving a stack 8 of book covers 2, for separating the book covers 2 from the stack 8 and for their forwarding arranged on the Deckenausbiegeeinrichtung 3. Downstream of the Deckenausbiegeeinrichtung 3 includes trained as a slide conveyor section 9, which for guiding the book covers 2 in the Figures 2 and 3 shown, lateral guide plates 5 has. On the conveyor section 9, two correspondingly curved book covers 2 are shown by way of example with a gap between them.

A stack 8 of book covers 2 is first introduced either directly into the ceiling magazine 7 or placed on a conveyor belt 10 arranged upstream of the ceiling magazine 7. In the latter case, the book covers 2 are conveyed by means of the conveyor belt 10 in the ceiling magazine 7, where the stack 8 forms again. The book covers 2 are thus transported starting from the supplied stack 8 on the ceiling magazine 7, the Deckenausbiegeeinrichtung 3 and the conveyor section 9 up to unillustrated association with the respective book block 61 in a flow 11, which in Fig. 1 is shown with a dash-dotted arrow.

Above the conveyor line 9 and in a main transport direction 1 of the book covers 2 immediately downstream of the Deckenausbiegeeinrichtung 3 then the device according to the invention is arranged in the form of a trap 4 designed as a tray. The Fig. 1 shows the tray 4 in solid lines in a rest position and with dashed lines in a relation to the rest position lowered catch position. The book production line 6 has an at least with the tray 4, the Deckenausbiegeeinrichtung 3, the conveyor line 9 and the conveyor belt 10 connected to the machine control 58.

The Figures 2 and 3 show perspective views of the tray 4 and the immediately upstream and downstream of the tray 4 arranged components of the book production line 6. In this case, the tray 4 in Fig. 2 in their rest position and in Fig. 3 shown in the lowered from the rest position fishing position.

The tray 4 is formed in a plan view substantially rectangular and has an upstream free end 47 and a downstream mounting end 41. In addition, the tray 4 has two aligned in the main transport direction 1 Support bracket 43, 44, a middle support 42 and at its free end 47 of the Deckenausbiegeeinrichtung 3 facing rod 50. In an area below the conveying path 9 is on both sides of the tray 4, that is, both on an operating side and on one of these opposite side frame each a cylinder 49 articulated with one end. The rod 50 is lowered by means of the cylinder 49 in the catching position and formed liftable in the rest position.

The center pad 42 is formed as a flat sheet metal, which can be placed on the rod 50 at the free end 47 of the tray 4. The center pad 42 is bent or folded at the free end 47 of the tray 4 with a rod 50 corresponding radius. Facing away from the Deckenausbiegeeinrichtung 3, the middle support 42 is rotatably mounted on the attachment end 41 of the tray 4 in a suspension about a rotation axis 45.

The tray 4 is mounted on both sides by means of the support bracket 43, 44 in the baffles 5. For this purpose, the support bracket 43, 44 in the region of the attachment end 41 bearing shoes 46, which are arranged displaceably on the baffles 5 in the main transport direction 1. In addition, the support brackets 43, 44 are each equipped with a vertical wall 52 ( Fig. 4 . Fig. 5 ), which guide the tray 4 during its pivoting from the rest position into the catching position and vice versa laterally along the baffles 5. At the free end 47 of the tray 4, the support bracket 43, 44 are similar to the middle support 42 designed, ie formed in the rod 50 hooked.

The center pad 42 is rotatably mounted on the attachment end 41 of the tray 4 about the rotation axis 45 and connected to a frame of the book production line 6, not shown. The support brackets 43, 44 are rotatably mounted in the safety shoes 46, i. they also rotate about the axis of rotation 45.

During operation of the book production line 6, the book covers 2 are conveyed in the flow 11 for Deckenausbiegeeinrichtung 3. In order to remove if necessary, at least one book cover 2 from the running through the book production line 6 flow 11, the tray 4 is lowered from its rest position and immersed in the flow 11 of the Deckenausbiegeeinrichtung 3 leaving book covers 2. After at least a single book cover 2 is placed on the tray 4, the latter is raised again and thus the discarded book cover 2 removed from the flow 11, so that the following book covers 2 downstream of the Deckenausbiegeeinrichtung 3 arranged conveyor track 9 can be freely supplied.

The FIGS. 4 and 5 allow a consideration of the tray 4 without the other components of the book production line 6. In this case, the connection of the two cylinders 49 with the rod 50 can be clearly seen. In this case, a free end 59 of the cylinder 49 faces the free end 47 of the tray 4. At its other end, the cylinders 49 are connected to the book production line 6. Furthermore, on both sides of the tray 4 is a hinge plate 53 a flapper 48, which is also attributed to the cylinder 49, with respect to the book production line 6 arranged stationary.

In the hinge plate 53 is a rotatably mounted about a further transverse to the main transport direction 1, horizontal axis of rotation 54 rotatably mounted, L-shaped angle lever 51 rotatably mounted in a kink 55 between two legs 56, 57 of the respective angle lever 51. Facing away from the further axes of rotation 54, the respective cylinder 49 is fastened rotatably on both sides of the tray 4 to a short leg 56 of the L-shaped angle lever 51, while the angle lever 51 receives the bar 50 on a long leg 57 ( Fig. 5 ).

In Fig. 6 is a section through the book production line 6 against the main transport direction 1 seen on the tray 4. Laterally outside, the flap 48 can be seen, which receives the rod 50. The support brackets 43, 44 are outside and the middle support 42 is placed centrally on the rod 50.

In the Fig. 6 shown baffles 5 are - shown in full line thickness - in a maximum outer position. Shown dashed lines, the baffles 5 are moved inwards to a minimum position transversely to the main transport direction 1. As a result, the flexibility of the tray 4 with respect to different ceiling formats (max, min) is illustrated.

Advantageously, all components of the tray 4 in a conventional book production line 6 without great installation effort can be used or inserted.

A corresponding method initially comprises identifying a mark 62 of both the book block 61 and the book covers with an identification device 63 and removing a book cover 2 as a function of an evaluation carried out in the machine control 58 of the book production line 6. The indicator 62 of the book covers 2 may be both an extra applied to the book covers 2 indicator 62 as well as based on the properties of the book covers 2, for example, the dimensions, the material or the print image indicator 62.

After the book production line 6 has been fed a stack 8 of book covers 2 and a number of book blocks 61, the machine control unit 58 assigns to this stack 8 of book covers 2 a record stored in the machine control 58 based on the identified marking 62 of at least one book cover 2 of the fed stack 8 to the order of the book covers 2 of this stack 8 to.

Due to the identified characteristics 62 of the supplied book block 61, an order of this book block 61 is determined in the machine control 58 and compared with the data set for the order of the book covers 2. As a result of this comparison, the machine controller 58 initiates the removal of at least one book cover 2 corresponding to the at least one missing book block 61 in the case of at least one book block 61 which is missing from the order of the book covers 2.

The book covers 2 leave the Deckenausbiegeeinrichtung 3 in flight, so that when lowered into the catch position tray 4 ( Figure 3 ) a book cover 2 after the other - the last supplied book cover 2 above - is placed on the tray 4 until it returns to rest ( Fig. 2 ) is raised. In this way, the delivery flow 11 with the tray 4 one or more book covers 2 are removed.

For this purpose, the short legs 56 of the angle lever 51 are moved in the direction of the Deckenausbiegeeinrichtung 3 when extending the cylinder 49 with the flap 48. As a result, tilt the long leg 57 of the angle lever 51 with the rod 50 upwards and the tray 4 is in its rest position ( Fig. 2 . Fig. 4 ). Conversely, a retraction of the cylinder 49 leads to lowering of the tray 4 in the catch position, ie for removing at least one book cover 2 from the flow 11 ( Fig. 3 . Fig. 5 ).

At rest, the tray 4 fly the book covers 2 below the tray 4 completely unhindered on the conveyor line 9 ( Fig. 1 ). The conveyor line 9 takes over the book covers 2 between the baffles 5, which are arranged parallel to the main transport direction 1 side of the book covers 2. The baffles 5 can be moved depending on the format transversely to the main transport direction 1.

In non-illustrated embodiments, removal of at least one book cover 2 from the conveying path 9 or at another position of the book production line 6 is alternatively provided. In this case, the book covers 2 are removed from the conveying stream 11 not in flight but lying on the book production line 6, for which purpose suitable shakers or suckers are arranged. The removed in this way, at least one book cover 2 is fed to a tray.
