Definitions

  • the present invention relates to cutting sheet materials, such as cardboard and more particularly the waste ejection station cutting, which follows the cutting operation of leaves.
  • the problem at this post is, in view of the high production rates, to achieve separation complete waste and cut shapes, so that that these do not disrupt operations following, such as stacking the cut products.
  • waste ejection devices for sheet material cutting machine comprising an upper table, a lower table to which is fixed a hulling board and a lower frame provided of tools, the tool attached to the upper table comprising a first contact point capable of pinching a pre-cut waste of a sheet between said first point contact and a tool attached to the lower frame when of a relative reconciliation of these tables.
  • the object of the invention is to obtain a rate of high success in waste separation allowing high production rates.
  • Another object of the invention is that the device does not requires little adjustment and manipulation and either sustainable.
  • the tool attached to the table superior including a first point of contact is the punch.
  • the means of cooperation advantageously include a second point of contact on the upper tool, says second point of contact being able to push on a second part of the lower tool; this is a simple way to achieve the desired effect, unlike complex mechanisms with levers or gears.
  • the moving part is preferably mounted on an axis of rotation, the lower tool comprising a return means to return said moving part to a position initial after the third phase of relative movement between the upper tool and the lower tool.
  • the first lower contact point and the second part of the lower tool advantageously form two teeth spaced apart on the moving part by a distance greater than the thickness of the waste.
  • the second tooth is preferably set back by relative to the first lower point of contact; this allows to have the second "tooth" of the tool below a level equal to or greater than the first "tooth” and thus allow for this second tooth to come overhang the waste.
  • the free end of the tooth formed by the second part of the lower tool is advantageously located at level of the underside of the sheet, which facilitates straddling waste.
  • the tool lower comprises a third part suitable for entering contact with the edge of the waste, said third part causing the said tranche in the direction of a distance compared to the edge of the adjoining sheet during relative approximation movement between the upper tool and the lower tool.
  • the lower tool is preferably recessed in the hulling board supporting the sheet and includes fixing means allowing its removal from the board top shelling.
  • Another object of the invention is a lower table for waste material cutting ejection station sheet which includes a plurality of lower tools an ejection device as described above.
  • the plurality of lower tools is located preferably essentially on one side of the periphery of each waste.
  • This direct action advantageously includes putting in contact with a second surface of the upper tool with a second part of the lower tool and includes the thrust of said second surface on said second part.
  • Figs. 1 and 2 are schematic sectional views of the waste ejection process.
  • Fig. 3 is a schematic sectional view of a failed ejection of waste.
  • Fig. 4 is a perspective view of part a hulling board fitted with the invention.
  • Figs. 5, 6 and 7 are detail views in section at different stages of ejecting waste.
  • Fig. 8 is a sectional view of another mode of realization of the device.
  • Figs. 9 and 10 are detail views in section of another embodiment of the two-stage device waste ejection.
  • Figs. 1 and 2 illustrate the normal course of a waste ejection operation during cutting of sheet material.
  • a sheet or flank 1 precut to the previous station, is brought on a board dehulling 2 secured to a lower table (not shown).
  • the shelling board 2 includes cuts 4 whose shape corresponds to those of waste 6 always connected by hooking points 8 to the side pre-cut 1.
  • a top table 9 with punches 10 is close to the hulling board 2, resulting rupture of the attachment points 8 and ejection of the waste 6 (Fig. 2).
  • Fig. 4 shows a peeling board 2 in which the lower tools 12 of a device according to the invention are embedded in the perimeter of a cutout 4.
  • Figs. 5, 6 and 7 show in more detail a device of the invention and its mode of operation.
  • the lower tool 12 of the device of the invention essentially comprises a pivoting moving part 14 about an axis 16 parallel to the plane of the board Shelling.
  • the axis 16 is mounted on a recessed support 18 in the shelling board 2.
  • the moving part 14 supports two projecting teeth-shaped members 20, 22.
  • the first tooth 20 projects into cutout 4 and is flush with the surface bottom of waste 6.
  • waste 6 is pinched between a first contact point 24 located on a tool attached to the upper table (here punch 10) and the first tooth 20.
  • the two tables continuing to be reconcile, waste 6 is removed from sheet 1 by the punch 10, which causes the workpiece to pivot mobile 14 and the projection of the second tooth 22 (more shorter than the first tooth 20) inside the perimeter of the cutout (Fig. 6).
  • Fig. 7 a third phase of ejection: the second tooth 22 enters in contact with a second contact point 26 provided also on the punch 10, which results in a acceleration of the angular movement of the moving part 14 and, consequently, the release of waste 6, which is ejected down.
  • the moving part 14 is returned to its position initial by a callback element, in this case a spring 28 acting on a lug 30 of the moving part 14.
  • This spring 28 can act in compression (see FIGS. 5, 6, 7) or in extension (see Fig. 8).
  • Figs. 9 and 10 use a spiral spring working in torsion.
  • contact points 24, 26 are placed on the punch 10 simplifies assembly. However, these contact points could be located on another body attached to the upper table.
  • the profiles of the contact points 24, 26 and of the two teeth 20, 22 are modeled on those of the teeth of a rack and pinion corresponding, taking into account, however, the thickness waste 6 to determine the width of the indentation 32.
  • the background of the indentation 32 can also be calculated so that the pivoting of the moving part 14 causes a forced separation of the edge of the waste cut 6 with respect to the edge of the cut sheet.
  • the cut pieces can be very shaped complex, it is of course beneficial that the tools lower 12 of the device occupy an area also as small as possible on the hulling board 2. From even, to facilitate handling when the tables upper and lower are disassembled, it is better that these tools 12 do not protrude significantly from the face bottom of the shelling board 2.
  • the support 18 is embedded in a groove in T or dovetail in the plank shelling 2 and can be removed from the top, which allows its possible replacement without it being necessary to dismantle the lower table.
  • the moving part 14, the axis 16 and the support 18 can be made of metal or a molded material with good mechanical properties such as nylon, etc.
  • a dynamic ejection device for waste precut in a sheet and including a tool upper and lower tool.
  • the waste is first pinched between the upper tool and the tool lower and then transported in one direction ejection.
  • the upper tool performs an action on the lower tool in order to release the waste, allowing it thus to evacuate freely.
