Definitions

  • the invention relates to a sheet application device according to the preamble of the first claim.
  • a device of this type is described in DE-PS 1 186 473.
  • the slots are tight and let the air blow out almost parallel to the sheet feed table, which should hold the sheet down in this area due to the blow-suction effect and at the same time drive it forward.
  • the blown air jets can also be inclined towards the edge regions of the arch in order to tighten the arch.
  • the blown air is controlled centrally by the air supply.
  • the disadvantage of this device is that it is not easily adaptable to different conditions, such as those that occur primarily due to different substrates. No differences can be taken into account regarding the transverse expansion of the paper sheets if they only occur during operation.
  • the smooth contact sheet creates a strong air cushion from the flowing blown air, especially with light paper types, and the effectiveness of the device is reduced.
  • a sheet lay-up device is similarly constructed, which is described in US Pat. No. 3,370,847.
  • Nozzles are arranged on the likewise smooth contact plate, which are blown with air. However, they are positioned at an angle between 5 and 45 against the plane of the contact plate, which is made dependent on the paper quality.
  • the main disadvantage is that limited nozzles are used, which then also act on the paper sheet at limited locations and are difficult to set correctly for light but also heavy papers.
  • Another disadvantage is the use of a smooth surface on the sheet feed table in the area of the nozzles because of the then strongly emerging air cushions.
  • DE-OS 2 638 784 describes a sheet feed table whose plate consists of a pattern-rolled sheet, which is used only for reasons of friction and the air in the recesses. Finally, the sheet feed table does not show any blow-suction elements for holding down the sheets.
  • Fr-A 2 252 215 it is known to change the size and shape of a slot nozzle by changing an intermediate layer and thus to influence the direction and volume flow.
  • the object of the invention is therefore to provide a device according to the preamble, which makes it possible to improve the sheet transport over the feed table in the area of the front marks with the most varied sheet materials and different operating conditions. It should be able to be adjusted during operation and ensure that the sheet fits snugly against the front marks even if the sheet materials are not uniform. At the same time, the separation of sheets lying on top of each other should be supported.
  • the slot is formed by a fixed and a movable edge, that the movable edge of the slot by adjusting devices vertically to the level of the sheet feed table in the height above its level and by further adjusting devices also in Distance to the fixed edge of the slot in the plane of the sheet feed table is adjustable and that the sheet-guiding surface of the sheet feed table between the slots and the front marks is provided with a uniform profile.
  • the setting can also be changed during operation and quickly adapted to sudden changes, for example of the paper.
  • the arrangement of a profiled sheet between the slots and the front marks is of particular advantage because the blown air can flow into the depressions of the sheet pattern and the paper thus lies on a weaker air cushion that can be metered more easily.
  • the setting range for the effect of the blown air is thus improved and the area of application of the device is expanded at the same time.
  • FIG. 1 shows the arrangement of the sheet feed table 1 together with the fixed contact sheet 2 and the movable contact sheet 3.
  • the fixed contact sheet 2 is located near the front marks 4 on the rear edge of the sheet contact table 1 as viewed in the direction of sheet travel.
  • the movable contact sheet 3 is moved through Bolts 5, springs 6 and nuts 7 connected to the sheet feed table 1.
  • the bores 8 in the sheet feed table 1 have a larger diameter than the bolts 5 and thus allow the bolts 5 to move when the contact plate 3 is adjusted.
  • the adjustment in height is carried out with setting cams 9 via setting pins 10.
  • the adjusting cams 9 are firmly seated on a shaft 11 which extends over the entire width of the device and can be rotated with the aid of a worm drive 12, 13.
  • the worm 12 is rotated from the handwheel 14 and moves the worm wheel 13 and with it the shaft 11.
  • the actuating cam 9 is moved relative to the actuating pin 10 and presses it up against the contact plate 3. This becomes, on the one hand, itself bent and on the other hand slightly raised in the spring-loaded mounting 5, 6, 7.
  • the contact plate 3 springs back into the starting position.
  • the movement of the contact plate 3 in the plane of the sheet feed table 1 is carried out via a connector 15 which is attached to the contact plate 3.
  • a set screw 16 is screwed, which is axially fixed relative to the sheet feed table 1.
  • the connecting piece 15 and with it the contact plate 3 are correspondingly displaced parallel to the plane of the sheet feed table 1.
  • the amount of adjustment of the contact plate 3 is indicated by pointers 18 via scales on the handwheels 14, 17.
  • the horizontal end position of the contact plate 3 is fixed by a safety device 16a in the thread of the set screw 16.
  • 2 shows the arrangement of the contact sheets 2, 3 on the sheet feed table 1.
  • the slot S lies between the front marks 4 and the side marks 19, which are only indicated here.
  • the contact plates 2, 3 are divided into four elements 2.1, 2.2, 2.3, 2.4 and 3.1, 3.2, 3.3, 3.4.
  • the movable contact plates 3.1, 3.2, 3.3, 3.4 were moved by two setscrews 16 over connecting pieces 15 in order to set the slot S in the plane of the sheet feed table 1.
  • the adjustment can be made asymmetrically, so that the opening of the slot S becomes larger on one side. Likewise, a different contour of the slot S can be set over the arc width.
  • the shaft 11 for setting the adjusting knobs 9 and the adjusting pins 10 on the contact plates 3.1, 3.2, 3.3, 3.4 lies parallel to the slot S under the sheet feed table 1.
  • the entire device is in turn arranged parallel to the sheet feed 20 of a sheet-processing machine 21.
  • Means for pre-aligning the conveyed sheets can be operated in the cutouts 22 in the contact sheets 2, 3. The sheets are moved in the direction of the arrow over the sheet feed table 1.
  • FIG. 3 shows a detail X from FIG. 1 on an enlarged scale.
  • the contact plate 2 is fastened on the sheet feed table 1.
  • the position of the contact plate 3 on the sheet feed table 1 is determined by the set screw 16 via the connecting piece 15 and by the setting cam 9 via the setting pin 10. The maximum adjustment is indicated by dashed lines.
  • a second embodiment in the same section of FIG. 3 is shown in FIG. 4.
  • the contact plate 3 ' is rigidly attached to the sheet feed table 1'.
  • the contact plate 2 ' is fastened movably on the sheet feed table 1' with the aid of the bolt 5 ', the spring 6' and the nut 7 '.
  • the sheet feed table 1 ' is worked across its width in the area of the contact plate 2' obliquely against the sheet running direction.
  • the contact plate 2 ' is drawn into this recess by the spring 6'. If the actuating cam 9 'is now rotated and pushes the actuating pin 10' up, the contact plate 2 'is also lifted up to the dashed position in the plane of the sheet feed table 1'.
  • the adjustment of the contact plate 2 'in the plane of the sheet feed table 1' is carried out with set screws 16 'by turning in a connecting piece 15'.
  • the end position is fixed by a fuse 16a 'in the thread of the pull rod 16'.
  • the bolts 10, 10 'and the connecting pieces 15, 15' are riveted, screwed or welded onto the contact plates 2 ', 3, the projection welding method would probably be preferable.
  • the height adjustment of the one slot edge does not have to be carried out via a setting cam 9.
  • Lever drives or wedge elements also serve the same purpose.
  • a cutout 23, 23 ' is provided in the contact plate 3, 3', to which holes 24, 24 'in the sheet feed table 1, 1' are assigned. These holes 24, 24 'are evenly distributed over the entire width of the sheet feed table 1, 1' and can be provided with connections 25 for the air supply as shown in FIG. 1. Each connection can be provided with a valve for throttling the blown air flow.
  • 5A shows the narrowest position of the slot S.
  • the blowing air from the bore 24 is deflected in the cutout 23 and emerges very steeply upwards due to the narrow position of the slot S. Only the kinetic energy from the horizontal deflection in the cutout 23 tends the beam approximately to the left.
  • 6B the slot S is fully opened horizontally by moving the contact plate 3 to the right. The blown air then emerges somewhat obliquely due to the enlarged slot opening and acts more in the direction of sheet travel.
  • the exit speed is lower because a larger volume could now flow through the now larger opening. As a result, the pressure difference at the slit becomes smaller and the outflow speed is proportional to this.
  • This characteristic is due to the falling characteristic curve of the centrifugal compressors most commonly used on sheet-processing machines for air supply and is also desired here.
  • the negative pressure that builds up the most at the edge of the slot S relative to the contact plate 3 depends on the exit velocity and the exit angle of the blown air jet.
  • FIG. 5C shows the edge of the contact plate 3 in its maximum height above the sheet feed table 1.
  • the blown air now exits the slot S at an angle.
  • the opening corresponds approximately to the case from FIG. 5B, since the adjustment path of the contact plate 3 is a maximum of 1 mm in both directions. Due to the stronger inclination of the blown air jet, the effect is now directed even more in the direction of sheet travel. This effect is strongest when the slot S is opened as shown in FIG. 5D.
  • the blown air jet emerges almost parallel to the surface of the sheet feed table 1 and thus takes the sheet most strongly in the direction of the front marks 4. In this case, the profile of the negative pressure in the vicinity of the blown air jet is very flat, thus showing a defined alignment with the front marks 4 there.
  • the importance of using the pattern-rolled sheet becomes important here.
  • the air that is blown under the bow makes it float on a smooth surface.
  • the blown air can at least partially escape through the depressions in the sheet pattern. This results in the effect that the sheet is easily guided over the elevations of the sheet as required by the slot setting and is therefore easier to control.
  • the sheet metal pattern is of course not necessarily limited to a concave-convex configuration, since other patterns are also conceivable with which the above-described effect can be achieved, such as groove patterns, diamond patterns or snake patterns.
  • the type of sheet is also not limited to rolled sheet, and sheets or cast semi-finished products can also be used.
  • FIG. 6 shows an overview of the entire sheet feeding device with sheet feeding table 1, contact sheets 2, 3, front marks 4, side mark 19, slot S and air supply path 24, 25.
  • sheet feeding table 1 contact sheets 2, 3, front marks 4, side mark 19, slot S and air supply path 24, 25.
  • the adhesive effect of the two sheets can be reduced by arranging blowers 28 on the frame 27 above the sheet feed table 1 and setting these blowers 28 behind the trailing edge of the sheet when the sheet is in contact with the front marks 4. They then blow air from behind under the upper arch, creating a slight arch separation between the first upper and the next lower arch.
  • a sheet stream 26 runs over the sheet feed table 1 and is carried by the conveyor belts 29.
  • the front edge of the first sheet is gripped and held down by the suction effect in the vicinity of the blown air. Waves in the sheet material are eliminated and the sheet is guided to the front marks 4 by the transport effect of the blown air flow.
  • the rear edge of the sheet comes into the area of the blower 28 and is blown with air. The air also passes under the arch and separates the first upper arch from the next lower arch, so that there is no longer any risk of the lower arch rolling over when the upper arch is pulled off.
  • the blowing and suction effect at slot S can be adjusted to different operating conditions. Thin sheet materials require less suction. Thick sheet materials, such as cardboard, require stronger suction and because their weight also stronger propulsion to the front brands. In poorly air-conditioned sheet stacks, malfunctions due to electrostatic effects or paper deformation occur during sheet processing. As described, all of these preconditions must also be met during operation by adjusting the slot S.
  • the joint adjustment of the two edges of the slot S by levers which are firmly connected on both sides can also be advantageous in such a way that one slot edge is moved up and the other is moved downwards by tilting one lever.
