Definitions
- the present invention relates to a device for turning sheets one by one at an automatic sheet output, in particular at the output of a printer connected to a computer, for example a laser printer.
- One solution adopted in particular by a manufacturer of laser printer under the trade name AGFA, consists in making a tray for receiving, or outputting, sheets comprising three sides.
- a first panel being vertical, a second forming an obtuse angle with said vertical panel and a third panel also forming an obtuse angle with said second panel.
- the tray is placed under the printer's paper outlet so that a sheet emerging from the latter comes to abut by its edge against the second inclined panel and pivots until its printed face comes against the vertical panel.
- the sheet then slides to the third inclined pan which serves as a receiving tray.
- the present invention therefore relates to a device for turning sheets at the outlet of a printer, which is independent of the reception tray, or the outlet of paper from the printer, adaptable to different types of paper and / or printers, and the cost of which is lower.
- the present invention relates to a device to be mounted oscillating at an automatic output of sheets to ensure the turning of the sheets one by one, characterized in that it is essentially made up of a wire, preferably metallic, shaped to present two coplanar mounting legs tilting on said outlet, two lateral sections having approximately the shape of an "S" and a median section having approximately the shape of a "U", the ends of the section in the shape of "U” "being connected to the respective ends of the lower loops of the" S "shaped sections.
- the device comprises a counterweight serving as means for adjusting the inclination of the device relative to the vertical, as well as means for adjusting the spacing between the ends of each "S" shaped section, which preferably consist of a "V" shaped section inserted between the
- a device for turning over a sheet of paper, the manufacture of which is particularly simple and which can be adapted to different types of paper and / or printers.
- FIG. 1 shows a side view of the part of a printer comprising the output of the printed sheets, provided with a device according to the invention and with a sheet collecting tray;
- FIG. 2 schematically shows four stages of turning a sheet by means of the dispositi according to the invention
- FIG. 3 shows in perspective a variant of the device according to the invention comprising a leaf collecting tray
- Figure 5 shows a top view of the device shown in Figure - ⁇ ;
- FIG. 6 shows in perspective a variant of the device according to the invention comprising an upper loop and shown at rest mounted on a support device;
- REPLACEMENT SHEET the part of a printer comprising the output of the printed sheets equipped with a support device receiving the device according to the invention in the rest position (FIG. 7), in the end of travel position (FIG. 8).
- FIG. 1 shows in partial side view, the rear part 1 of a printer known as. the non-commercial AGFA model P 400.
- This includes a conveyor belt 2 used to take the sheets out of the printer.
- a turning device 3 according to the invention consisting of a metal wire, is held below the belt 2 by means of two rings, in which the two ends 5 of the wire engaging the device 3 engage.
- metal wire has approximately an S-shaped section laterally.
- a sheet collecting tray 6 is placed at a distance from the printer 1 which is fixed by the length of the parts 7 serving to maintain the distance between the protective sides 8 of the sheet outlet. This tray 6 does not serve to turn the sheets, can be of greater capacity.
- a sheet 9 leaving the printer 1 slides towards the device 3 with its printed side 10 above.
- This sheet 9 comes into abutment by its lower edge 13 against the inside of the lower loop 11 of the "S" shaped section, by sliding on the outside of the upper loop 12 of the "S" shaped section (FIG.
- the sheet continues to slide on its edge 13 towards the bottom of the loop 11 (figure 2-B) by driving the piece 3 slightly towards the printer (arrow 14) by pivoting the ends 5 of the wire in the rings 4
- REPLACEMENT SHEET unfolds outwards due to the fact that its lower edge 13 abuts against the bottom of the lower loop 11 of the "S" shaped section and that the part 3 restores towards the rear (arrow 15) the movement which the sheet 9 when it came into abutment (figure 2-A).
- the sheet 9 then unfolds and ejects from the device 3, being almost horizontal and having its printed face below (FIG. 2-D).
- the sheet 9 then falls into the collecting tank 6 ( Figure 1).
- the latter has an inclined face 28 so as to ensure good deposition of the sheet 9 in the tray.
- FIG. 3 represents a variant of the device according to the invention in which the device 3, consisting of a metal wire, is suspended from a mobile collecting tank 16 thus making it possible to place the turning device under the paper outlet of any which printer, by fixing the tray 16 to the support 17 of the printer 18.
- This support may for example consist of a simple table.
- the device 3 is maintained in the same way as above, that is to say by means of two rings 19 formed in the tank 16 and in which engage the two ends 5 of the metal wire.
- the wire is given a shape such that it has two lateral sections in the form of an "S" 20 and a middle section 21 which follows the curve of the lower loop 11 of each section in the form of an "S" 20 and which has the shaped like a "U".
- the latter is extended in the embodiments shown in FIGS. 3, 4 and 5, beyond the bottom 22 of the loop 11 of the "S" shaped sections 20, while the embodiment shown in FIGS. 1 and 2 , stops at the bottom 22 of the loops 11.
- REPLACEMENT SHEET embodiment of the device in which it is adjustable according to the type of paper and / or printer.
- a mobile counterweight 23 is added to the "U" section 21, this being maintained in the position chosen by a screw 24 which has the effect of tightening the "U" section 21 in the manner of a vice.
- This counterweight 23 makes it possible to adjust the counterweight of the lower loops 11 and thus the inclination of the device.
- the "S" shaped sections 20 are modified so as to present an additional "V” shaped loop 25 between the two loops of the "S" shaped sections.
- This loop 25 has notches 26 on one of its sections and a ring 27 surrounds each loop in a "V” shaped section 25 and is retained by one of said notches 26.
- This adjustment of counterweight and spacing must be made according to the type of paper and the type of printer so that the sheet does not escape from in front of the device, which is the case if it is too inclined towards the printer and that the sheet can eject from the device once turned over, which is not the case if the device is too inclined towards the collecting tray.
- FIG. 6 represents a variant of the device according to the invention mounted on a support device.
- the device according to the invention is here equipped with an upper loop 28 consisting of a wire, preferably metallic.
- This loop consists of a "U” shaped section with at each end 29 a "V” shaped section in a perpendicular plane. Each end 29 is brazed to the upper part of the "S" shaped sections 20.
- REPLACEMENT SHEET fitted with its upper loop 28 allows it to be mounted on the support device.
- Said loop serves as a balancing counterweight, bringing the center of gravity of the device closer to its tilting axis giving it great sensitivity.
- Said loop determines the position at rest and the maximum stroke position of the device according to the invention.
- the means for adjusting said positions is to create a permanent deformation of the loop 28 by bending up or down.
- the device is balanced during construction. It may be advantageous to modify it by adding a counterweight 35 to the upper loop 28.
- the support device consists of a wire, preferably metallic, shaped in such a way that it has a "U" shaped section 30. Each end of this section is continued symmetrically by a "S" shaped section 31 followed of a section in the form of "U” 32 then of a section 33 in the form of "L".
- the "U" shaped sections 32 serve as bearings at the ends 5 of the device according to the invention.
- a connecting bar 34 in the shape of a "U" symmetrically connects the branches of each section 32, then connects the two sections 32 together.
- Figures 7 and 8 show the device according to the invention in its location on the printer known under the trade name of AGFA P400.
- This implantation is carried out by means of a device, consisting of a metal wire, fixedly mounted under the paper outlet, supporting the device according to the invention.
- FIG. 7 represents the device according to the invention in the rest position ready to receive a sheet of the paper output.
- the device according to the invention is balanced so that in this position, the upper loop 28 comes to bear on the connecting bar 34 of the support device acting as a stop.
- FIG. 8 shows the device according to the invention in the sheet ejection position. Indeed, under the mass of the sheet, the turner leaves its position at rest to find a balance, and describes a circular arc backwards until the upper loop 28 comes to bear against a stop.
- the upper stop is the paper outlet 2 of
