EP4034390B1 - Apparatus and method for automated production of book covers and/or box lids - Google Patents

Description

The present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 8.

In a case machine with a horizontal processing principle [ Liebau, Heinze; industrial bookbinding; Verlag Berufs und Schule, 1997; p.: 399ff ] Cardboard covers and a spine insert made of cardboard or paperboard are combined with the cover blanks provided with adhesive in a rolling device. A generic case machine is also in the DE 100 57 599 A1 shown and described. The cardboard covers are ejected from a cardboard magazine and, together with the spine insert, aligned laterally on guide rails and fed to the rolling device. Synchronously to the cardboard feed, the reference blank is brought into the roll-on level via a blank cylinder. The protruding edges of the book cover are then folded in consecutive workstations either continuously or at a standstill, usually first the protruding edges at the top and bottom, and after the corners have been folded in on the sides. Finally, the book covers are guided between the press rollers of a pressing device to rub the cardboard parts onto the reference panel. In a delivery, the finished book covers are stacked on a roller table for manual removal.

Such book cover machines are used for the mass production of identical book covers or box covers in high production output. The uninterrupted production of different book or box covers is possible if they have the same format, ie the same dimensions in terms of open width, height, cover width and spine width and the supplied reference grooves of the same format but only different print content. The known book cover machines are always set up for a specific cover format.

In the event of a format change, the case machine is converted to the new dimensions while the case machine is at a standstill. Although in the meantime in the book cover machines of the generic type, the essential changeover processes are automated by motorized adjustment axis systems via a central control device and essentially take place in parallel, each format change is associated with a time-consuming set-up process, which is economically disproportionate to the actual format, especially in the case of small runs of only a few book covers production time stands.

The DE102010024232A1 suggests positioning guide elements during ongoing production and in a timely manner according to a book cover to be produced. A respective adjustment is carried out as soon as the respective processing of the preceding ceiling or ceiling parts has been completed. Such a conversion of the guides of the cardboard feed, which align the cover boards and spine inserts, as well as the folding devices of the side folding station, makes it possible to produce book covers of different opened widths without interruption. The format of the cover board cannot be changed either in terms of height or width during ongoing production. The different open widths are only achieved by changing the position of the cover boards in relation to one another.

In the 1 The case machine shown schematically processes a cardboard base sheet 900 and a blank base sheet 905 into a multi-part base 908. It enables the production of bases of different formats with continuous production, i.e. with the machine running with bases of different formats still being processed from cardboard base sheets or blank base sheets of the same format . For this purpose, it comprises a cardboard feed 1, a blank feed 2, an adhesive application device 3 and a joining device 4 arranged along the transport path of the blanks, as well as a wrapping device 5 and outfeed 6. The control device 8 is used to control the drive motors 118, 206, 207 and the infeed devices 105, 107, 109, 119, 121, 503, 507 and other actuators 300 of the different devices 1, 2, 3, 5 of the ceiling machine. The devices 1, 2, 3, 5 of the ceiling machine are explained below.

The cardboard feeder 1 has a cardboard magazine 10 . This cardboard magazine 10 stores a stack of raw cardboard sheets 900 of the same format. A first separating device 11 separates the cardboard base sheet 900 lying at the bottom from the supply stack. First transport elements 101 push this bottommost unprocessed cardboard sheet 900 under the stack in a first cardboard transport direction A. The cardboard transport device 12, which is connected to the cardboard magazine 10, takes over the separated unprocessed cardboard sheet 900 and transfers it to the joining device 4.

The board transport device 12 has a first transport section 13 and a second transport section 14 with a second transport direction B of the boards 900, 901, 902, 903 in succession downstream. This second transport direction B is collinear with the ejection direction A of the first separating device 11 .

A cardboard cutting device 15 with a first longitudinal cutting device 16 is arranged downstream of the first separating device 11 in the first cardboard transport direction A along the cardboard transport device 12 . This first longitudinal cutting device 16 is arranged in the area of the second transport section 14 and comprises two first circular shears 106. The upper circular blade 115 and the lower circular blade of the two first circular shears 106 have the same axis of rotation. The axis of rotation of the upper circular blade 115 and the axis of rotation of the lower circular blade run parallel to the cardboard transport plane and transverse to the cardboard transport direction A, B.

The two first rotary shears 106 are arranged at a distance from one another in the cardboard transport path along the common axes of rotation in such a way that the supplied cardboard sheets are each separated into three cardboard elements 901, 902, 903 as they pass through.

Each of the first rotary shears 106 is drive-connected to an infeed device 107 in each case. The infeed devices 107 are controllably connected to the control device 8 of the ceiling machine via a first data line 801 . They each have infeed elements of a known type, such as spindle drives, with infeed directions transverse to the second board transport direction B of the boards 900 in the second transport section 14.

Arranged downstream of the first longitudinal cutting device 16 is an in 2 shown spreading device 18. This spreading device 18 positions cardboard elements 901, 902, 903 of the same cover transversely to the second transport direction B to one another.

For this purpose, it generates different transport directions D, E of the outer cardboard elements 901, 902, which are oriented with the second transport direction B in a common plane. The fourth transport direction D and the fifth transport direction E are therefore not parallel to one another, rather they enclose an angle of separation α.

This angle of spread α between the fourth transport direction D and the fifth transport direction E is greater than 0°. It is guided by left guide rollers 112 and generated by right guide rollers 113. The left-hand guide rollers 112 and the right-hand guide rollers 113 are each mounted in a bar above the cardboard transport plane in such a way that they apply a normal force to the outer cardboard elements 901, 902 to be transported. The axes of rotation K of the guide rollers 112, 113 have a lead angle β to the second transport direction B. This advance angle β can be changed in that the respective bar with the guide rollers 112, 113 is pivoted about an axis oriented perpendicularly to the plane of the cardboard by an angle of rotation γ, δ. Feeding devices of a known type, not shown in the figures, are provided for this setting of the lead angle β.

The displacement of the cardboard elements 901 , 902 transverse to the second transport direction B caused by the spreading device 18 is limited by a second guide rail 104 and by a third guide rail 120 . The guide rollers 112, 113 push the respective cardboard element 901, 902 laterally against the second guide rail 104 or against the third guide rail 120, which determine the lateral position and the angular position of the respective cardboard element 901, 902. To adapt to different formats and different lateral distances between the cardboard elements 901, 902, 903 of a blanket, the second guide rail 104 can be positioned transversely to the second transport direction B by a sixth controllable infeed device 119 and the third guide rail 120 by a seventh controllable infeed device 121 . This sixth controllable infeed device 119 and seventh controllable infeed device 121 are connected by data lines 801 to the controller 8 of the blanket machine.

A second longitudinal cutting device 17 is arranged along the cardboard transport path between the first separating device 11 and the first longitudinal cutting device 16 . It comprises circular shears as the second cutting tool 108 . The second cutting tool 108 can be positioned transversely to the second transport direction B. For this purpose, it has a third controllable infeed device 109. This third controllable infeed device 109 is also connected by a first data line 801 to the control device 8 of the blanket machine. An automatic adjustment of the second cutting tool 108 to a desired cardboard format, even during ongoing production, is thus possible.

Downstream of the second longitudinal cutting device 17, the cardboard feed 1 has a first discharge device 19. The first discharge device 19 discharges the section 904 separated from the cardboard in the second longitudinal cutting device 17 from the first cardboard transport line 100 attached penetrating top to bottom. With regard to the individual cut, the diverting element 117 is stationary but can be moved transversely for a format setting.

In addition, the cardboard supply 1 has a first cross cutting device 45 within the first cardboard transport path 100 . The cross cutting device 45 makes it possible to cut the raw cardboard sheets 900 to a desired smaller sheet height. The transverse cutter is formed from a pair of cooperating cutting cylinders each having knives 114 mounted on the periphery thereof. The cutting cylinders extend transversely to the first transport direction A over the first cardboard transport track 100. A controllable drive is assigned to them. A changeable, non-uniform movement profile of the rotation allows the cardboard to be cut to different heights in cycles in a simple manner. Another removal device, not shown for reasons of clarity, guides the section out of the first cardboard transport line 100.

The cutting devices 16, 17, 45 enable the cover machine to produce covers 908 of different formats from a uniform format of the raw cardboard sheets 900. This means there is no need to stock different raw cardboard formats. In addition, a format-related setting of the cardboard magazine 10 is not required.

Opposite the cardboard feed 1 or the joining device, the cover machine has a blank feed 2. The blank blanks 905 are stored as a stack in the blank magazine 20. Above the benefit magazine 20 is a second separating device 21. This separates the respective top sheet of the remaining blank stack and feeds it to a transport device 22.

A third longitudinal cutting device 23 is provided following the panel separation 21 along its transport direction C. Like the second longitudinal cutting device 17, it has circular shears 202, which can be positioned transversely to the panel transport direction C. For this purpose, a further controllable infeed device is assigned to the circular shears 202 . This third longitudinal cutting device 23 enables the cover machine to cut a blank blank sheet 905 that has been fed in to the required blank width.

A second transverse cutting device 24 downstream of the third longitudinal cutting device 23 in the transport direction C allows the blank blank sheet 905 to be cut to the required blank height. The second transverse cutting device 24 is formed from a knife 203 cutting against a stationary cutting bar. Together with the third longitudinal cutting device 23, any smaller panel formats can be cut from a raw panel panel.

A corner kick-off device 25 is arranged downstream in the product flow. It comprises two pairs of cutting cylinders spaced coaxially and variably with respect to one another, each with two spiral-shaped cutting edges. The two spiral cutting edges of a cylinder are arranged opposite one another and have opposite gradients. The corner kicking device 25 also has a controllable individual drive. In this way, the corners of the leading and trailing edges of the blank sheet can be pushed off in the run by diagonally running cuts.

The panel transport device 22 feeds the individual panels through the cutting devices 23, 24, 25 to the adhesive application device 3. For this purpose, a blank cylinder 400 with grippers 401 fixes the leading edge of the blank blank and guides it along the adhesive application device 3 on its lateral surface. This is composed of a beam Nozzles 300 formed. However, a roller gluing unit of a known type can also be used.

The cardboard feed direction a, B affects the blank cylinder 400 in such a way that the glued blank blank is rolled onto the cardboard elements as it passes through. A counter-pressure wave 403 arranged in the joining area generates additional pressure on the bonded parts.

The workpiece produced in this way runs through the wrapping device 5 of the ceiling machine. This includes two impact devices 50, 51 of a known type. The head and foot impact device follows the joining device 4 . Strips 501 extending transversely to the transport direction B of the cardboard elements 901, 902, 903 straighten up the preceding and following projections of the glued copy by a substantially vertical relative movement to the cardboard elements 901, 902, 903 along the first bending lines 500 formed by cardboard edges . Wrap-in rails 502 turn the erected supernatants by linear movements parallel u to the transport direction B of the cardboard elements 901, 902, 903 onto the inside of the ceiling and rub them against the cardboard elements 901, 902, 903.

All wrapping elements 501, 502, 505, 506 are assigned controllable infeed devices 503, 507, through which they are positioned to match the ceiling format to be manufactured.

The complex of parts is then brought into the side wrapping device and placed on support rails 505. Second wrapping rails 506 pivot from a starting position below the lateral cardboard overhangs onto the covers 901, 902. In doing so, they grasp the lateral blank overhangs and fold them along lateral bending lines 504 onto the cardboard 901, 902.

The finished folded blankets 908 pass through a rolling device which is arranged downstream of the wrapping device 5 and which presses the adhesive sheets 901, 902, 903, 909 together as they pass through. A subsequently arranged discharge device 6 transports the covers 908 out of the cover machine in order to make them available for further processing or intermediate storage.

For good usability of the magazines 10, 20, these are arranged at approximately the same ergonomic height as the outlet 6. For this purpose, the transport directions A, B, C, D, E of the cardboard feed 1 are oriented upwards from the cardboard magazine 10 to the joining device 4 .

The ceiling machine also includes a controller 8 with a data memory 800, in which production parameters and the production orders assigned format data of the finished and to be produced ceilings 908 and their individual parts 901, 902, 903, 909 and starting materials 900, 905 are stored.

All controllable delivery devices 105, 107, 109, 503, 507 are connected to controller 8 by first data lines 801 and all controllable drives 118, 205, 206, 207 by further data lines 803. The controller 8 uses this to supply the drives 118, 205, 206, 207 and delivery devices 105, 107, 109, 503, 507 with product- and production-dependent target values using the data stored in the data memory 800. Actual values are sent to the controller 8.

A detection device 700 is present in the area of blank feed 2 . This captures an identification present on the blank 905 as soon as a blank 905 passes through its capture area 701 . By way of example, a camera is used as the detection device 700 , which reads the data matrix code printed on the blank and transmits the detected information to the controller 8 via a data line 802 . The setpoint specifications of the drives 118, 205, 206, 207 and infeed devices 105, 107, 109, 503, 507 are determined from the identifier and transmitted to them.
