Definitions

  • the invention relates to a vibrating table for vibrating material in sheet layers, for example stacked printed sheets.
  • Vibrating tables generally have a tiltable support table, the support table having a vibrating plate with a support surface for placing the stacked goods on, a rear stop for the stacked goods placed on top and at least one lateral stop for the stacked goods placed on top, the support table being tiltable from a horizontal position in the direction of the two stops.
  • a vibrating table also has a vibrating device that is designed to set the vibrating plate of the support table in a vibrating movement. The inclination of the support table and the vibrating movement of the vibrating plate ensure that the individual layers of sheets or sheets are aligned with the stops with their edges precisely.
  • the stacked goods are generally clamped between the vibrating plate and the clamping device using a clamping device and the air between the individual layers of the stacked goods is spread out using a movable air spreader. After venting, the stack or stacked goods are presented as a compact block and can be fed to a subsequent cutting station, for example.
  • a vibrating table with blowing devices is used, for example, in the DE 43 07 361 A1 described.
  • the object of the present invention is to further develop a vibrating table in such a way that it ensures rapid, edge-accurate alignment of the material to be vibrated even with large sheet layers, high weight and/or low grammage.
  • the vibrating table according to the invention is provided with two opposing blowing devices, each of which blows air into the stacked goods in the direction of the other blowing device.
  • blowing air from opposite sides of the stacked goods has a beneficial effect on the precise alignment of the individual layers of sheets during the shaking process. It is therefore intended that during the shaking process, air is blown into the stacked goods from both the rear edge and the front edge. It is intended that the front edge, which is therefore free of a stop, is exposed to blowing air using one or more slot nozzles. Blowing air from the front edge has the advantage that the stacked goods can be exposed to blowing air over a large width, basically over the entire width of the front edge, since there are no stops there to prevent or hinder the blowing of air. This makes it possible to blow air into the stacked goods and thus between the layers of sheets along the front edge across the entire width.
  • one slot nozzle or several slot nozzles are directed together in the vertical direction, thus perpendicular to the support surface or perpendicular to the support surface. to the stacking direction of the stacked goods, which has proven to be particularly advantageous with regard to precise and rapid alignment of the sheet layers during the jogging process.
  • the front edge is exposed to blowing air over its entire width, or at least over a large part of the entire width, thus over at least 50% of the entire width, using the front blowing device, this is not necessary in the area of the rear edge. Rather, it has proven to be particularly advantageous if air is only blown in locally in the area of the rear edge, i.e. in individual areas spaced apart in the width direction, using the air nozzles of the counter blowing device spaced apart in the width direction.
  • an air flow of the air blown in by the blowing device is at least twice as large as an air flow that is blown in by the counter blowing device.
  • the one or more slot nozzles are arranged in such a way that a closed or substantially closed, flat air board is blown into the sheet layers in the region of the leading edge, which extends over at least 50%, preferably over at least 60%, in particular over at least 90% of the width of the stacked goods.
  • the one or more slot nozzles cover a distance in the width direction which corresponds to at least 50% of the width of the support table.
  • the injection device has at least four, preferably at least six, in particular at least seven individual slot nozzles. It is considered particularly advantageous if these slot nozzles are arranged in such a way that the slot nozzles lie adjacent to one another without gaps or almost without gaps in the width direction.
  • the nozzles of the injection device are slot nozzles, this is not mandatory for the nozzles of the counter-blowing device. Rather, it is considered advantageous if the air nozzles of the counter-blowing device have a round, in particular circular, outlet cross-section.
  • the cross-sections of the air nozzles in the vertical direction are 90% to 110% of the cross-sections of the slot openings of the slot nozzles in the vertical direction.
  • a nozzle does not necessarily, but preferably, have a cross-sectional constriction.
  • the counter-blowing device has at least four, preferably at least five, in particular at least six air nozzles. It is considered particularly advantageous if the counter-blowing device has a maximum of ten air nozzles.
  • the air nozzles of the counter-blowing device take up no more than 10% of the width of the support table.
  • the blowing device has a first blower device for supplying the slot nozzles of the blowing device with air and the counter blowing device has a second blower device, which operates independently of the first blower device, for supplying the air nozzles of the counter blowing device with air.
  • the vibrating table has a control device for controlling the injection device and the counter-blowing device, wherein the control device is designed to control the first blower device and the second blower device such that the injection device outputs a volume flow V_In and the counter-blowing device outputs a counter-volume flow V_Counter, wherein a ratio of the volume flow to the counter-volume flow (V_In/V_Counter) is at least 3.0.
  • the air nozzles of the counter-blowing device can be moved in the vertical direction. In this context, it is considered particularly advantageous if the air nozzles of the counter-blowing device can be moved less in the vertical direction than the one slot nozzle or the several slot nozzles of the injection device.
  • the air nozzles and the slot nozzles are designed to move in the vertical direction, in particular to move back and forth, during the shaking process.
  • the air nozzles of the counter-blowing device it is considered particularly advantageous if the air nozzles are formed in a lower region of the rear stop with respect to the vertical direction.
  • the rear stop has through slots that extend in the vertical direction, with the nozzles being movable along the through slots. It is certainly conceivable that the nozzles pass through the through slots.
  • the design with through slots has the advantage that air that is blown in can also escape through the through slots, which prevents air from building up in these areas.
  • the vibrating table has a portal frame connected to the tiltable receiving table, wherein the one slot nozzle or the several slot nozzles are mounted in the portal frame so as to be movable in the vertical direction.
  • the portal frame can be moved parallel to the support surface in a longitudinal direction perpendicular to the rear stop in the direction of the rear stop. This makes it easy to adjust the distance of the one or more slot nozzles to the rear stop in order to achieve optimal adaptation to different formats of the sheet layers of the stacked goods.
  • the portal frame has a first linear guide extending in the vertical direction, wherein the one slot nozzle or the several slot nozzles are mounted so as to be movable together in the first linear guide.
  • a hold-down plate that can be moved perpendicularly to the support surface and aligned parallel to the support surface is mounted in the portal frame.
  • the hold-down plate prevents the topmost sheet layer or layers from being deflected too much or even completely detached from the rest of the stacked goods due to the relatively large amount of air or strong air flow from the slot nozzles of the blowing device.
  • the hold-down plate serves to secure or maintain the stacked shape of the stacked goods. It is entirely conceivable that the hold-down plate is arranged at a distance from the topmost sheet layer to allow the sheet layers to float. In particular, the hold-down plate should not press on the topmost sheet layer or push the stacked goods to the Press the support table, otherwise the floating required for alignment would not be possible.
  • the hold-down plate is fixed in position to the portal frame with regard to its orientation in the width direction.
  • This design is particularly simple and uncomplicated to achieve. In practice, it has been shown that regardless of whether the support table is tilted towards a left stop or a right stop, a fixed hold-down plate is sufficient to achieve the desired effect. Adjusting the hold-down plate has proven to be not absolutely necessary.
  • the hold-down plate is preferably a cut-to-size plate made of cardboard or plastic, which has a magnetizable or magnetic coating and is magnetically attached to a carrier element connected to the portal frame and which can be moved in the vertical direction.
  • This type of design has the advantage that the plate can be easily adapted to the format of the stack to be shaken by cutting it accordingly.
  • the plate is preferably cut in such a way that the format of the sheets of the stack to be shaken is covered over the entire surface or almost entirely.
  • the one or more slot nozzles can be moved along the width direction and fixed in position in the width direction using a fixing device. This allows adaptation to the direction of inclination of the support table and thus to the position of the stacked goods during the shaking process, since the width covered by the slot nozzles is generally smaller than the width of the support table. If the support table is tilted to the right during shaking, the one or more slot nozzles are also moved to the right in advance and then fixed in position in this position. If the support table is tilted to the left during shaking, the one or more slot nozzles are also moved to the left in advance and then fixed in position in this position.
  • the vibrating table has a linear guide extending in the width direction, whereby the one or more slot nozzles are mounted together in the linear guide so that they can move and can be fixed in position in the width direction using a clamping device.
  • the position can be fixed, for example, by clamping using a quick-release device.
  • the linear guide can be a rail guide, for example.
  • the multiple slot nozzles can be moved together in the width direction.
  • the multiple slot nozzles can be moved independently of one another along the width direction, whereby the slot nozzles can be arranged further apart to cover a wider format, or closer together to cover a smaller format in the width direction.
  • the blowing device preferably comprises a plurality of slot nozzles, the blowing device having a support bar extending in the width direction, the slot nozzles each being detachably attached to the support bar.
  • This allows the blowing device to be quickly and easily adapted to the width format of the stacked goods.
  • a larger width format a larger number of slot nozzles are used than with a smaller width format.
  • the problem is that with a smaller width format, air flows past the side of the stacked goods, which has a detrimental effect on the shaking result.
  • the slot nozzles protrude laterally from the side edge of the stacked goods, there is the problem that any side stop cannot be moved up to the side edge of the stacked goods.
  • the support bar has a plurality of quick-release devices arranged next to one another in the width direction for releasably fastening the slot nozzles to the support bar, wherein a suspension structure is attached to the respective slot nozzle, wherein the respective slot nozzle is suspended in one of the quick-release devices by means of the suspension structure, wherein the respective quick-release device comprises a clamping device for clamping the position of the respective suspension structure in the quick-release device.
  • the clamping device is preferably manually operable and comprises a toggle lever.
  • the quick-release device can be designed as an eccentric clamp, for example.
  • the support bar has at least four, in particular at least six, preferably at least eight, particularly preferably exactly eight quick-release clamping devices for releasably fastening the slot nozzles to the support bar.
  • the respective slot nozzle has a centering element that protrudes in the width direction, wherein the centering element of the slot nozzle is inserted into a corresponding centering opening of the adjacent slot nozzle in order to center the slot openings of the adjacent slot nozzles.
  • This ensures that the slot openings are aligned as precisely as possible with one another in the case of detachable slot nozzles. If the slot openings are offset in the vertical direction, the same sheet layer would be underflowed by the air emitted by one slot nozzle and overflowed by the air emitted by the other slot nozzle, which would have a detrimental effect on the shaking process.
  • the slot nozzles are suspended in the quick-clamping device and can be moved to a limited extent in the width direction when the quick-clamping device is released, in order to insert the centering element of the slot nozzle into the centering opening of the adjacent slot nozzle by moving it, or vice versa.
  • the quick-clamping device is then clamped, thereby fixing the corresponding slot nozzle in position.
  • the one or more slot nozzles can be pivoted towards the support surface in order to change the outflow direction of the air emitted by the slot nozzles with respect to the support surface.
  • the outflow direction of the air emitted by the The air emitted by the slot nozzles is slightly inclined to the support surface, in particular in order to flow through the lower layers of sheets, since the support surface of the support table limits the downward movement of one or more slot nozzles.
  • discharge channels are formed on the rear stop, which are spaced apart from one another in the width direction, extend in the vertical direction and are closed at the rear for discharging the air blown in between the layers of the stacked material by means of the blowing device and exiting at the rear edge in the vertical direction.
  • the discharge channels are preferably open at their lower end facing the support surface.
  • the discharge channels are preferably open at their upper end facing away from the support surface.
  • the rear stop has several spacers that protrude in the direction of the stacked goods, extend perpendicularly to the support surface and are spaced apart in the width direction, such that a vertically running outlet channel is formed between two adjacent spacers.
  • These spacers can certainly be formed by separate elements that are connected to the rear stop. It is entirely conceivable that the spacer elements are detachably connected to the rear stop in order to achieve an adjustment of the discharge channels by exchanging the spacers.
  • the respective discharge channel has a depth of at least 15 mm.
  • depth is understood to mean the extent of the respective discharge channel in a direction perpendicular to the width and perpendicular to the height.
  • the air nozzles of the counter-blowing device are arranged in the area between the discharge channels. It is also considered particularly advantageous if the discharge channels are free of air nozzles In a further embodiment, at least one discharge channel is arranged between the air nozzles of the counter-blowing device.
  • the rear stop has several spacers, with an air nozzle of the counter-blowing device being formed in every second spacer.
  • air nozzles formed in a spacer are spaced from a front edge of the spacer. This avoids damage caused by an excessively strong air flow of the air exiting the air nozzles or even mechanical contact between the respective air nozzle and the rear edge of the stacked goods.
  • the vibrating table has a stop ruler that can be moved in the width direction in order to guide the stacked goods into to limit its movement in the width direction and, if necessary, to push protruding layers of sheets into the stacked goods by pushing the movable side stop closed. It is also quite conceivable that this movable side stop carries out a tapping movement during the shaking process in order to promote or accelerate the alignment of the stacked goods during the shaking process.
