Definitions

  • the present invention relates to a device for loading insert sheets for inserting between stacks of poses in a reception area of a station for receiving the poses.
  • the present invention also relates to a station receiving station, a machine for processing sheet-like elements and a method of transporting an insert sheet in a reception area of a station receiving station.
  • the separation of the poses consists, after shaping and complete ejection of the waste, to break the attachment points between the poses of a sheet by means of a male upper tool and a female lower tool mounted vertically one above the other in the leaf receiving area.
  • the upper tool consists of pushing elements slightly smaller than the perimeter of the poses.
  • the lower tool consists of a grid whose mesh shape generally corresponds to the perimeter of the poses. The poses fall through these meshes and stack in vertical stacks in the reception area.
  • Inserting involves placing an insert sheet, such as a full sheet, between stacks of poses. So that this inserting can be carried out without requiring a concomitant shutdown of the production unit, a device commonly known as a non-stop reception grid is used.
  • an insert sheet is grabbed from a stack of insert sheets arranged near the reception area.
  • the insert sheet is then dropped onto the non-stop pose reception grid.
  • the non-stop receiving grid carrying the insert sheet then moves under the lower blanking tool.
  • the non-stop receiving grid returns over the stack of insert sheets to receive a new sheet. Leaving the reception area, the grid crosses the teeth of a comb which has pivoted into the retaining position to retain the insert sheet and thus the poses stacked on this insert sheet, in the reception area.
  • the non-stop reception grid thus allows the deposit of an insert sheet between the stacks of poses and the support of the poses during the evacuation of the stacks of complete poses without stopping production.
  • the document DE 195 16 023 A1 describes an inserting device which lifts an insert sheet on a stack using a pivoting arm fitted with a suction cup and then deposits it on an inserting grid when the latter leaves the zone for receiving the poses .
  • the suction cup device is then moved aside in order to allow the grid to rise, then to be inserted in the zone for receiving the poses.
  • the grid then lowers at a speed that corresponds to the rate of production of the poses. When the grid reaches a low position, it leaves the zone for receiving the blanks to receive a new insert sheet.
  • the insert sheet remains in the poses reception zone thanks to a vertical grid which retains it.
  • the document does not specify how the insert sheet is fixed and detached from the insert grid, nor how its position on the grid is adjusted.
  • the displacement of the grid or the tray carrying the insert sheet towards the reception area must be carried out quickly to insert the insert sheet as quickly as possible between the last deposited pose on the top of the stack and the next.
  • the relatively large stroke to be carried out and the high production rates which may require, for the grid or the tray, displacement speeds of the order of 1 m / sec, keeping the insert sheet in position. turns out to be tricky.
  • the accelerations and decelerations may be too sudden to properly entrain the insert sheet. It may happen that when it arrives in the reception area, the insert sheet is offset or skewed and thus finds itself badly positioned between the stack poses.
  • One of the aims of the present invention is to propose an improved device for loading inset sheets making it possible to ensure the correct positioning of the inset sheet during its transport in the reception area.
  • the subject of the present invention is a device for loading insertsheets comprising a movable carriage for inserting insertsheets in a reception area of a poses reception station, the movable carriage comprising a plurality of longitudinal bars, characterized in that at least one longitudinal bar has a suction channel opening out through at least one suction orifice on the face of the longitudinal bar intended to receive an insert sheet, the channel d the suction being configured to be connected to a vacuum source for holding by suction the insert sheet transported by the mobile carriage.
  • the insert sheet is thus well maintained in position on the mobile carriage for its transport to the reception area, despite the accelerations and decelerations of the mobile carriage.
  • the subject of the invention is also a station for receiving the poses of a machine for processing elements in the form of sheets, characterized in that it comprises a device for loading inset sheets as described above.
  • the invention also relates to a machine for processing elements in the form of sheets, characterized in that it comprises a station separation station as described above.
  • the transverse direction T is the direction perpendicular to the longitudinal direction of movement D of a sheet, as illustrated by the arrow D on the figures 1 and 2 .
  • the horizontal plane corresponds to the (L, T) plane.
  • upstream and downstream are defined with reference to the longitudinal direction of movement D.
  • the sheets move from upstream to downstream, generally following the main longitudinal axis of the machine, in a movement clocked by periodic stops.
  • flat elements and “sheets” will be considered equivalent, and will relate to elements composed of corrugated cardboard as well as flat cardboard, paper or any other material commonly used in the packaging industry. It is understood that throughout this text, the terms “sheet” or “element in sheets” or “element in the form of leaves” very generally designate any print medium in the form of leaves such as, for example , sheets of cardboard, paper, plastic, etc.
  • the figure 1 shows an example of processing machine 1 for processing sheets.
  • This processing machine 1 is conventionally composed of several work stations which are juxtaposed but interdependent one by one to form a unitary assembly.

  • each sheet takes place in the transformation station 300, for example between a fixed plate and a lower movable plate of the press 301 for cutting the sheets according to a matrix corresponding to the developed shape which is wishes to obtain, for example in order to obtain a plurality of boxes of a given shape.
  • the movable stage rises and falls successively once during each machine cycle.

  • the ends of the clamp bars 75 are each connected respectively to a side chain forming a loop, commonly called chain train 80.
  • Chain train 80 Two chain trains 80 are thus arranged laterally on each side of the clamp bars 75.
  • the set of gripper bars 75 will start from a stopped position, accelerate, reach a maximum speed decelerate, then stop, thus describing a cycle corresponding to the movement of a sheet from one workstation to the next workstation.
  • the chain trains 80 move and stop periodically so that, during each movement, all the gripper bars 75 engaged with a sheet are passed from one station to the adjacent downstream work station. Each station performs its work in synchronism with this cycle which is commonly called machine cycle.
  • the workstations are in the initial position to start a new job at the start of each machine cycle.
  • the number and nature of the processing stations in a processing machine 1 can vary depending on the nature and the complexity of the operations to be performed on the sheets. In the context of the invention, the concept of processing machine thus covers a very large number of embodiments due to the modular structure of these assemblies. Depending on the number, nature and arrangement of the workstations used, it is indeed possible to obtain a multitude of different processing machines. It is also important to underline that there are other types of work stations than those mentioned, such as embossing, upsetting stations or such as stations for loading stripes for stamping for stamping machine or foil stamping machine. hot foil stamping in which one carries out between the platens of a press, the deposit on each sheet, of patterns from a film from one or more bands to be stamped. Finally, it is understood that the same processing machine may very well be equipped with several stations of the same type.
