Definitions

  • the present invention concerns a device for storing sheets in piles rotary machines, generally coupled with the outlet of a system of conveyor belts.
  • the disks and the system of conveyor belts operate at properly synchronized speeds to allow a single sheet to be stored in each pocket of the disks.
  • Sheets are thus transferred to a discharging area, generally placed below the group of disks, where sheets find one or more projecting elements arranged between the disks.
  • the sheet stop with respect to the rotation of the disks allows the sheet to be removed from the pocket and to be positioned, by fall down, on top of the pile that is going to be formed. Each complete pile is then removed from the discharging area by known means.
  • the precision and good operation of said devices also depend on the characteristics of the material of the sheets, in particular on the weight of each sheet, on its thickness and rigidity.
  • An object of the present invention is to provide a device which allows the formation of piles each consisting of a well defined number of sheets, independently from the materials from which sheets are obtained and from the speed at which sheets are removed from the disks pockets, namely capable of operating in a reliable way at high speeds, with similarly high productivity.
  • a device for storing up sheets in piles in rotary machines comprising at least a conveyor belt at the outlet of which a plurality of equal disks, coaxially and axially spaced from each other is provided, each disk carrying receiving pockets volutedly arranged towards the outside; and one or more fixed retaining elements, projecting between said disks in correspondence with a discharging station of said sheets, characterized in that the bottom of at least one of the pockets in each of said disks is offset in a radial direction, towards the disk center, with respect to the bottom of the adjacent preceding pocket, in the direction of rotation of the disks themselves; and in that at least a separating means for sheet piles sheets is able to be inserted, in correspondence with said retaining elements, in the space between said offset pocket bottoms, said separating means following subsequently the sheets further deposited out of the pockets.
  • the number of pockets comprised between two subsequent offsettings is equal to the number of sheets in each pile, or is a submultiple of said number of sheets, thus allowing the formation of one or more piles consisting of a well determined number of sheets for each rotation cycle of the disks.
  • the separating means are movable between the disks, synchronized therewith, according to a prefixed cyclic run from an upper position in correspondence with said offsetting(s) to a lower position below said pockets.
  • Said separating means advantageously comprise one or more fingers insertable between subsequent piles of sheets.
  • Figure 1 shows one of the disks 1 receiving the sheets 2 from a group of cooperating conveyor belts 3, said sheets being introduced into the pockets 4.
  • the disk 1 rotating clockwise with the other disks in figure 1, carries the sheets 2 in correspondence with a discharging station 5.
  • separating means 7 act between the disks, said means comprising at least one finger 8 and moving with cyclic movements synchronized with the disks.
  • At least one pocket 9 is provided, whose bottom is offset in a radial direction, towards the disks centre, with respect to the bottom of the adjacent pocket 10 preceding the pocket 9 in the direction of rotation of the disks themselves.
  • the pockets 9 and 10 define in the disks a space 11, not opened for being occupied by any sheet, that includes the connecting surface 12, for instance a step, between the bottom surfaces of the pockets 9 and 10.
  • the bottoms of the pockets immediately subsequent to one of said offsettings, before the following offsetting in the direction of rotation of the disks consist of curved surfaces with a radius of increasing size.
  • Figure 2 is a magnified view of a detail of the device that clearly shows the separating means 7 in the position in which the relevant fingers 8 intercept the space 11, the fingers 8 being at the height of the connecting surface 12 of the offsetting between the bottom of the pockets 9 and 10.
  • the sheet in the pocket 10, stopping against the projecting elements 6, lies below the fingers 8, while the sheet in the pocket 9, lies above the fingers 8 and is then separated from the previous one.
  • Figure 3 represents a cross sectional view of a preferential embodiment of the device comprising the disks 1 and the separating means 7, the latter ones being in the position where the fingers 8 find themselves below the pockets 4.
  • the separating means 7 are associated with means for the removal of piles.
  • the latter comprise pivots 13 that are preferably positioned between each pair of means 7 for the separation of piles, but with possibility of reciprocal sliding between pivots 13 and means 7.
  • the offsettings between the bottoms of the pockets on the disks, together with said means to separate the piles of sheets, provide the device with a great precision in all applications, independently from the operation speed of the device and from the materials constituting the sheets.
