    Automatic collating machine Field of the Invention The present invention relates to an automatic collating machine comprising one ormore feeding stations and an endless conveyor belt, which endless conveyor belt hasan upper run and a lower run between two conveying wheels, which upper run has anoperational moving direction and supports one or more collecting units, which one ormore collecting units are attached to said endless conveyor belt, each of said one ormore collecting units comprises a bottom and a side wall upstanding at a front edge ofsaid bottom in said operational moving direction, each of said one or more collectingunits has a downwardly inclination angle in relation to said upper run and in said oper-ational moving direction in order to receive sheets from said one or more feeding sta- tions.
    Background of the Invention EPl726552 discloses a machine for collecting printed products, comprising a continu-ous traction device (e.g., a conveyor belt) to which conveying elements for receiving aprinted sheet from a plurality of feeding stations are fixed. In an embodiment, each ofthe conveying elements has a bearing surface delimited by a wall on the front end andinclined towards the wall, wherein the wall is aligned perpendicularly to the bearing surface.
    When a conveying element transporting a stack of printed sheets shall move around theconveying wheel and at the same time shall transfer the stack to a second conveyor beltfor further processing, the trailing part of the conveying element rises so high that thestack lands on the second conveyor belt such that the sheets are not anymore piled stablyand ordered, which translates in problems for the further processing (e. g., packing) of the product.
    Hence, there is a need in the technical field of automatic collating machines for printedproducts of overcoming the aforementioned drawbacks of the state-of-the-art solu- tions.
    Object of the InventionThe object of the invention is to assure that the stack of printed sheets remains stableand ordered after being transferred from a first conveyor belt to a second conveyor belt.
    Description of the Invention The aforementioned object of the invention is achieved by an automatic collating ma-chine as described in the preamble of claim 1, wherein each of said one or more col-lecting units comprises a plurality of plate segments, which plurality of plate segmentsare individually pivotal during their passage around a conveying wheel, each of saidplurality of plate segments comprises a front plate segment, which front plate segment comprises said side wall, and a rear plate segment.
    Due to the fact that the plate segments have a shorter length in the operational movingdirection than he total length of the bottom, the outer radius during the movementaround the conveying wheel is smaller that it would be with a bottom consisting of only one single plate.
    The sheets which form a stack in a collecting unit will be placed against the front wallin a secure way due to the inclination of the bottom. Furthermore, the feeding speed ofthe individual sheets may be slightly higher than the operational moving speed of theconveyor. Hereby the individual sheets will be “forced” against the front wall in a se- cure way.
    The advantage of the invention is that when a collecting unit shall move around a con-veying wheel and, at the same time, shall transfer the stack of printed sheets to a fol-lowing conveyor belt for further processing, the plurality of mutually displaceableplate segments perrnits to the trailing part of the collecting unit not to rise so high.Thereby trailing end of the stack will only be lifted slightly or would not be liftedwhen the plate segment moves around the conveying wheel. Therefore the stack willbe transferred with the bottom arranged along a substantially rectilinear line and willland stable and ordered after the passage between the two conveyor belts. It is possible for the plate segments to pivot independently of each other.
    With the present invention it is thus possible to operate with a comparable large bot-tom in the collecting unit and simultaneously avoid the need to have large diameter of the conveying wheels in order to have a stable transfer of a stack to the following belt.
    In an embodiment of the invention, a plurality of feeding stations is placed in a subse-quent order with respect to said operational moving direction. The advantage of thisembodiment is that an arbitrarily high number of stacks may be produced at the sameprocess line and an arbitrarily high number of different printed products from differentproviders may be stacked together (e.g., one provider per feeding station), thus greatly increasing the efficiency of the collating process.
    In an embodiment of the invention, one or more feeding stations are placed above saidendless conveyor belt. The advantage of this embodiment is that the printed sheets falldown directly in the collecting units. Nevertheless, in another embodiment, said one ormore feeding stations are placed on a side of said endless conveyor belt and the print- ed sheets are pushed into said collecting units.
    In an embodiment of the invention, a plurality of collecting units is placed in a subsequentorder with respect to said operational moving direction. The advantage of this embodimentis that an arbitrarily high number of stacks may be produced at the same process line, thus greatly increasing the efficiency of the collating process.
    In an embodiment of the invention, said plurality of collecting units is mutually, equallyspaced. The advantage of this embodiment is that a more predictable interaction betweenthe one or more feeding stations and the collecting units is achieved. Also, this makesthe programming of the automatic collating machine easier. Nevertheless, an arbitrarily spacing between the collecting units may also be used.
    In an embodiment of the invention, said front and rear plate segments are attached bystrips of flexible material. In another embodiment of the invention, each of said plural-ity of collecting units is made of one piece of flexible material. Said flexible material may be rubber, for example. The advantage of these embodiments is that the collecting 4 units may cope With the deformation provoked When moving around conveyor Wheels ofvarious radii Without the risk of tearing apart. At the same time, these constructions Would produce a very low operating noise.
    In an embodiment of the invention, said plurality of plate segments comprise one ormore interrnediate plate segments placed between the front plate segment and the rearplate segment, Wherein said one or more interrnediate plate segments are individuallypivotal With respect to each other and/or With respect to the front and rear plate seg-ments. The advantage of this embodiment is that the process is more easily customiza- ble, for example, With respect to the radii of the conveyor Wheels.
    In an embodiment of the invention, said plurality of plate segments are detached fromeach other. The advantage of this embodiment is that the noise produced by the collect-ing units is totally cancelled With respect to other embodiments of the invention Wherethe front, interrnediate and rear plates are attached together by one or more joints, forexample. Nevertheless, all types of constructions are covered by the invention, since, forexample, the front segment may be detached from the interrnediate segment, Whereas the latter may be instead attached to the rear segment by one or more j oints.
    In an embodiment of the invention, said plurality of detached plate segments are de-tached from each other of 8 mm in a direction parallel to said endless conveyor belt.The advantage of this embodiment is that the printed sheets do not fall or get stuck inbetween the plate segments of the collecting unit. Moreover, the front and rear platesegments do not collide With each other right before or after moving around the con- veyor Wheels.
    In an embodiment of the invention, said front and rear plate segments have the sameinclination angle. The advantage of this embodiment is that the printed sheets slidedown in the collecting unit Without curling, thus forrning one after each other a stable and ordered stack.
    In an embodiment of the invention, said plurality of detached plate segments are de- tached from each other of 2 mm in a direction perpendicular to said endless conveyor belt, wherein said rear plate segment is higher than the front plate segment. The ad-vantage of this embodiment is that there is no risk that a printed product (i.e., one ormore sheets) that slides over the bottom of the collecting unit will be caught and fas- tened in the space between the two plate segments.
    In an embodiment of the invention, a trailing part of said rear plate segment is parallelwith respect to said endless conveyor belt. The advantage of this embodiment is thatthe trailing part will follow a smaller radius when passing around a conveying wheelthat a plate in which the trailing part have same inclination as the remainder of thebottom. This will further prevent the stack from rising too much when transferred from a collecting unit to a second conveyor belt.
    In an embodiment of the invention, said endless conveyor belt comprises a number oftransporting belts, which number of transporting belts are transversally aligned with respect to said operational moving direction.
    In another embodiment of the invention, said number of transporting belts is three.The advantage of this embodiment is that even a small printed product can be trans-ported by the automatic collating machine of the invention by resting on the middle collecting unit, which is attached on the middle transporting belt.
    It is noted that the width of the transporting belts shall be dimensioned in such waythat it is possible to operate with two transporting belts in a following conveyor. Thetwo belts being arranged between the three transporting belts of the first conveyor inorder to form a stable support for the stacks even if the stack is formed of sheets hav- ing a short length in direction transversal to the operational moving direction.
    Moreover it is beneficial if the is substantial distance between the transporting belts itorder to obtain a directionally stable support for the collecting units seeing that a mi-nor displacement of the aligned collecting units will only influence slightly on the ori-entation of the stack which shall have their leading edge arranged substantially trans- versal to the operational moving direction. 6 In an embodiment of the invention, each of said number of transporting belts compris-es an equal number of collecting units, which number of collecting units is transversal-ly aligned with respect to said operational moving direction, each of said number ofcollecting units comprises a front plate segment and a rear plate segment. The ad-vantage of this embodiment is that such a design allows a higher operating speed ofthe machine as the mass of the machine elements to be swung about the conveyor wheels is only half.
    In an embodiment of the invention, each front and rear plate segments have a widthless or equal to that of the transporting belt to which they are attached to. For example,each collecting unit may be 75 mm large and each transporting belt 100 mm large.Hereby 12.5 mm free belt is provided on each side of collecting units. This allows theuse of support rollers bearing on the two outerrnost parts (10 - 12.5 mm) of the con- veyor and which still allows the collecting units to pass between the support rollers.
    Dimensioning of the collating machine is a compromise seeing that it is desired tohave collecting units as large as possible in order to give a support for larger sheetshowever the collating machine shall also be able to give secure support for smallersheets resting only on an interrnediate of three aligned collecting units and simultane-ously the machine shall be able to establish a secure transfer of such stack to a follow- ing conveyor.
    Hereafter the invention will be described in connection with a drawing illustrating an a non-liming example for an automatic collating machine.
