Definitions

  • the present invention relates to a method and a machine for the automated production of book covers according to the preamble of claim 1.
  • Machines of this type are known as book cover machines, in which, in a continuous pass, cover boards and a back insert are matched in a pass-fitting manner with the reference provided with adhesive in a roll-on device.
  • the protruding edges of the trim benefit are wrapped in successive workstations, either in a flowing pass or at a standstill, i.d.R. first the edges protruding from the head and foot and, after the corners have been pulled in, the edges protruding from the sides.
  • the book covers are guided between press rollers of a pressing device, in which separate systems rub the cover boards and the back insert on the reference utility.
  • the book covers pass as a stack over a roller table for manual acceptance.
  • the adhesive for example from the DE 100 57 599 A1 , known as two-roller gluing units in book cover machines.
  • the adhesive usually an animal hot glue or a dispersion adhesive, is pumped by the adhesive conveyor from a reservoir between the rollers. Due to the rotary movement of the applicator roll, adhesive is led out through the gap present in the vicinity of the application and metering rollers. A part of the adhering to the applicator roll adhesive is then discharged in a rolling motion on the reference benefit.
  • the thickness of the job is determined by the distance between the rollers, which is why the metering roller is arranged displaceable by manual, acting on the two bearings adjusting the applicator roll.
  • a two-roller gluing unit is known in which the metering roller is pressed with a defined force against the applicator roll to produce a thin adhesive film on the applicator roll.
  • hydraulically connected hydraulic cylinders are provided so that even with inaccurate adjustment of the threaded spindles sets a uniform application of force to the two bearings of the metering and forms a nip of almost constant width over the entire width of the roller .
  • the disadvantage is that the gap width increases with increasing back pressure in the vicinity of the rollers, which then reinforced by the already high back pressure much more adhesive than desired is carried out.
  • the two-roller gluing unit is suitable for gluing with constant roller speeds.
  • the reference provided individually by a feed is taken over by the so-called utility cylinder with grippers, transported along the applicator roll and into a roll-up device for the adhesive application.
  • the transfer of the reference benefits transported in a plane from the transport device to the utility cylinder preferably takes place in a plane parallel to a tangent of the utility cylinder.
  • the beginning of the reference benefit to be detected by the grippers of the utility cylinder is directed to the utility cylinder.
  • the reference benefit is thereby stiffened and there is a distortion-free transfer of the aligned reference utility.
  • a die cut to the contour of the reference benefit to be glued is tensioned onto the utility cylinder.
  • This die increases the diameter of the utility cylinder in the of the. Reference benefits covered area opposite the exposed area.
  • the free area of the utility cylinder is sufficiently spaced from the applicator roll to avoid contact of the utility cylinder with the adhesive on the applicator roll while ensuring adhesive transfer to the utility benefit.
  • the die must be so precisely tailored and positioned on the mantle of the utility cylinder that repeatable on the one hand, the reference benefits are evenly supported, especially at the edge regions to their edges, on the other hand, the die with respect to the reference not.
  • the preparation of the utility cylinder for different reference blank blanks is very expensive.
  • Such book cover machines serve the mass production of identical book covers in high production capacity. Continuous production of various book covers is possible only if they have the same format, i. have the same dimensions in terms of open width, height, lid width and back insert width and the supplied reference benefits of the same format but only different pressure content.
  • the known book cover machines are thus always set up for a specific book cover format. Small and very small runs can not be manufactured economically in this way.
  • the invention achieves the object by a device having the features of claim 1.
  • Advantageous developments of the invention are characterized by the features specified in the subclaims.
  • the Walzenleimwerk known type is replaced by a Beleimvorraum with at least one controllable adhesive applicator.
  • Adhesive-free areas within the ceiling format are also easy to produce.
  • Another advantage of the controllable nozzle adhesive application is an adhesive film that is easily replaceable during production, both product-by-product and modifiable within a product, as well as easy adjustment of the application to the speed of transport of the adhesive. It is irrelevant whether the nozzle application is directed to the scratchessnutzen or on the cardboard elements. In principle, non-contact nozzles and also contact nozzles can be used as application nozzles.
  • the machine comprises an application roller known from conventional ceiling machines for transferring the adhesive to the reference benefit, which is stretched along this application roller via a utility cylinder.
  • the applicator roll rotates at a slightly lower peripheral speed than the utility cylinder, the reference used on the respectivelyzylinder is securely clamped and prevented its postponement.
  • the application image of the adhesive produced by the nozzle or the nozzles on the application roller is compressed in accordance with the difference in the roller speeds.
  • the at least one nozzle is directed onto the utility cylinder for a direct application of adhesive.
  • the significantly reduced duration during which the adhesive is exposed to the ambient air can be seen to advantage.
  • climatic influences on the quality can be significantly reduced and the adhesive properties such as, for example, viscosity and solids content, influenced much more directly.
  • unwanted effects of different production speeds and order levels can be minimized.
  • the setup effort in the Production of different formats significantly reduced and an uninterrupted production of consecutive different formats possible.
  • An arrangement of a multiplicity of nozzles, of which several are grouped together, is advantageous.
  • the nozzles of a group each share a common adhesive supply and a common control.
  • the effort can be kept low with high variability of the adhesive application.
  • it is simultaneously possible to selectively apply different adhesives and adhesive amounts in order to optimize the bonding according to the expected local stress of the bond.
  • a detector is advantageously provided for detecting the position of the reference utility to be glued. By detecting the actual position of the reference benefit, the beginning and the end of the adhesive application can be controlled particularly precisely.
  • a rotary encoder can be used to detect the angular position of the useful cylinder. Such a rotary encoder also serves to detect the rotational speed of the useful cylinder and thus the transport speed of the reference utility in the order area, which allows a simple and accurate adjustment of the applied amount of adhesive to the transport speed.
  • slot dies allow a simple, flat application and a small number of nozzles held in a simple manner.
  • an adaptation of the applied adhesive width to the utility width is particularly simple and variable.
  • FIG. 1 shows a simplified schematic representation of a first embodiment of a book cover machine, which book covers 1 produced by joining glued reference Use 2 with cover cardboard 3 and back inserts 4.
  • the reference benefits 2 are transferred with a payload to a continuously rotating about a horizontal axis of rotation 20orzylinder 19, which takes over the reference benefits 2 with grippers 21, passes on a Beleimvorraum described later 22 and again emits in the startup point.
  • a left and a right cover cardboard 3 as well as a back insert 4 are fed by a cardboard feed 12 to the contact point.
  • separately acting pressure rollers 37 ensure that the reference benefits 2 bubble-free on the cover cardboard 3 and the back insert 4 are rolled.
  • the onlyzu operation has a per se known utility magazine 16 which singles the respective lowest reference benefit 2 of a stack 48, pushes out in the transport direction 15 and feed rollers that pull away the reference 2 under the stack 48 and transfer to a known alignment device.
  • the reference grooves 2 aligned at a standstill in the alignment device at the front edge and on one side are accelerated by means of acceleration rollers to the continuous transport speed of a utility transport device 17 transporting the reference webs 2 over a plurality of cycles and subsequently transferred to them.
  • a light barrier monitors the arrival and removal of the reference benefits 2 in the alignment.
