[0004] From DE 43 07 361 A1 a vibrating device is known which has a swivellable and vibrable pile rest, a front stop and swivellable side stops which are simultaneously designed as gas discharge devices.

[0005] From US 2016 / 0167411 A1 an inkjet printing machine is known, in the delivery section of which a blowing device is used to cool the sheets and prevent them from sticking together.

[0006] From DE 100 03 024 A1 a vibration device is known which has a swivellable and vibrable pile placement device and a front stop and a side stop, the stop being simultaneously configured as a gas discharge device.

[0008] From DE 4000263 A1 a vibrating device is known in which the stop has a vibrating drive. A lift plate arranged below the pile-forming area and a press plate arranged above the pile-forming area can grip and lift a pile together.

[0009] From DE 30 33 648 A1 a method is known in which a sheet pile is punched and air is repeatedly forced out of the sheet pile by means of a striking arm during the punching process.

[0010] From DE 322 098 A1 a vibrating device is known which has a swivellable and vibrable pile placement device and fixed front and side stops. In addition, two stops are arranged movably, one of which can eject air towards the sheet forming area during the downward movement. To move these stops, their suspensions protrude through openings in the placement surface.

[0011] The object of the present invention is to provide a vibration device and a method for operating a vibration device.

[0012] This problem is solved according to the invention by the features of claim 1 and by the features of claim 2 as well as by the features of claim 18.

[0013] The vibrating device is configured, for example, for arranging the sheets in a sheet pile and / or for carrying out a vibration process for turning a roughly stacked sheet pile into a smoothly stacked sheet pile. The vibrating device has at least one pivotally arranged pile placement device, by which a placement plane is determined, the position of which is fixed relative to the pile placement device. The placement plane preferably separates an upper half space from a lower half space. The vibrating device has at least one first front stop, by which the pile forming area is and / or can be limited in a first conveying direction, i.e. the conveying direction is preferably from the pile forming area towards the front stop, more preferably perpendicular to the boundary plane of the pile forming area determined by the front stop. The vibrating device has at least one first side stop, by which the pile-forming area is and / or can be limited, in particular in a transverse direction perpendicular to the conveying direction. The resting plane preferably forms a lower limit of the pile-forming area. The vibrating device has a pile ventilation device, in particular configured as a rear blowing device. The pile ventilation device has at least one gas discharge device, which can be arranged in different positions relative to the pile resting device or the pile support surface. The pile-forming area is preferably arranged between the at least one gas discharge device and the at least one front stop with respect to the first conveying direction. In a preferred refinement, the at least one gas discharge device is arranged so as to be movable between at least one respective lowered position and at least one respective ventilation position, in particular movable vertically. Preferably, at least one gas discharge device is arranged at least partially in the upper or first half-space in its respective at least one ventilation position. Preferably, at least one gas discharge device is arranged completely in the lower or second half-space, i.e. in particular not in the upper or first half-space, in its respective at least one lowered position.

[0014] This has the advantage that the entire sheet of the sheet pile can be influenced by the blowing device, but no collision between the blowing device and the pile placement device can occur. This also applies preferably when the sheet dimensions are shorter than the maximum format, especially if a corresponding receiving opening is provided. Nevertheless, maximum mobility of the sheet during its transport is guaranteed.

[0015] In an alternative or additional refinement, the vibration device is preferably characterized in that at least one gas discharge device has one discharge opening or gas discharge opening or a plurality of discharge openings or gas discharge openings, the discharge opening or openings extending vertically over an entire length of at least 15 mm, preferably at least 20 mm, more preferably at least 25 mm, even more preferably at least 35 mm, even more preferably at least 50 mm. This allows a particularly large portion of the sheet pile to be loosened simultaneously. Preferably, the maximum height of the stationary sheet pile is at most 55 mm, more preferably at most 30 mm.

[0016] In an alternative or additional refinement, the vibrating device is preferably characterized in that it has at least one upper pile limiting element, which is and / or can be arranged at least temporarily above the pile forming area and limits the pile forming area upwards. In this case, a particularly large gas volume can be blown into the sheet pile without the sheet pile being destroyed. This allows the sheet pile to be particularly loosened and allows a particularly efficient smoothing of the sheet pile. In an alternative or additional refinement, the vibrating device is preferably characterized in that the at least one upper pile limiting element is movable between at least one upper limiting position and at least one lower limiting position. In particular, the at least one upper pile limiting element is arranged higher in the vertical direction in its at least one upper limiting position than in its at least one lower limiting position.

[0017] In an alternative or additional refinement, the vibration device is preferably characterized in that it has at least one inner upper pile limiting portion which limits the pile-forming area in the upward direction in at least one inner region which is spaced apart from the edge of the pile-forming area in each horizontal direction by at least 10 mm, preferably at least 20 mm, more preferably at least 50 mm, even more preferably at least 100 mm, even more preferably at least 200 mm. In this case, the intermediate region can be limited upwardly independently of the edge region, which allows an optimized mode of operation of the at least one upper pile limiting portion. In an alternative or additional refinement, the vibration device is preferably characterized in that it has at least one upper pile limiting part formed as an edge limiting part, which limits the pile-forming area upwardly in at least one edge area, which edge area is spaced away from the edge of the pile-forming area in at least one horizontal direction by a maximum of 50 mm, preferably a maximum of 20 mm, further preferably a maximum of 10 mm and even more preferably a maximum of 5 mm.

[0018] In an alternative or additional refinement, the vibrating device is preferably characterized in that, with respect to the first conveying direction, the pile forming area is arranged between at least one gas discharge device and at least one front stop. In an alternative or additional refinement, the vibrating device is preferably characterized in that the discharge direction determined by the at least one gas discharge device has at least one component that is oriented parallel to the first conveying direction. The discharge direction is preferably parallel to the first conveying direction. In this case, the gas discharge device can always be used, regardless of the width of the sheets. In this case, it is also advantageous to blow gas or air into the sheet pile from behind, since selectively one of the two side stops located opposite each other can be used. Furthermore, the sheets are not only subjected to a force by the tilt position, but also additionally by the blown gas or gas mixture towards the front stop.

[0019] In an alternative or additional refinement, the vibrating device is preferably characterized in that at least one, preferably a plurality, more preferably each, of the gas discharge devices each has at least two or at least three discharge openings, which are arranged above one another in the vertical direction, in which case different, specifically adapted pressures or volume flows can be applied to different areas of the sheet pile in the vertical direction.In an alternative or additional refinement, the vibrating device is preferably characterized in that the narrowest point of the lowermost gas supply line leading to the lowermost of the multiple discharge openings of the respective gas discharge device has a larger cross-sectional area through which the flow can pass than the narrowest point of the uppermost gas supply line leading to the uppermost of the multiple discharge openings of the respective gas discharge device.

[0020] In an alternative or additional refinement, the vibration device is preferably characterized in that the at least one gas discharge device is arranged separately from the movable part of the vibration drive and / or the pile placement device is arranged pivotably independent of the at least one gas discharge device. This makes the vibration device particularly robust with respect to the at least one gas discharge device. The pile placement device is preferably coupled to a movable part of the vibration drive. In an alternative or additional refinement, the vibration device is preferably characterized in that the pile placement device has at least one receiving opening, in particular a plurality of receiving openings, and the at least one gas discharge device is arranged at least partially movable through the respective receiving opening in order to be transferred between at least one respective lowered position and at least one respective ventilation position. This allows an optimized, for example format-adapted, arrangement and positioning of the at least one gas discharge device simultaneously with the optimization of the vibration movement. In an alternative or additional refinement, the vibration device is preferably characterized in that at least one receiving opening extends in the sliding direction, which is preferably oriented parallel to the discharge direction and / or the first conveying direction, and the at least one gas discharge device is movable in the sliding direction while the at least one gas discharge device protrudes through the respective receiving opening into the upper half-space and / or is arranged transferably in different longitudinal positions with respect to the sliding direction between at least one respective lowered position and at least one respective vent position, for example at least one receiving opening extends over a length in the sliding direction of at least 20 mm, preferably at least 50 mm, more preferably at least 100 mm, even more preferably at least 200 mm.

[0021] In an alternative or additional refinement, the vibrating device is preferably characterized in that at least one receiving opening has a respective gas guide surface at an end located opposite the respective discharge opening in the sliding direction and / or the discharge direction and / or the first conveying direction, the upper end of the gas guide surface being arranged further away from the respective discharge opening than the lower end of the gas guide surface, so that gas is supplied to the underside of the lowest sheet, improving the mobility of the sheet. In another alternative or additional refinement, the vibrating device is preferably characterized in that the upper surface of the pile resting device has at least one resting area and at least one gas guide area, the at least one resting area and the resting plane are in tangential contact with each other, and the at least one gas guide area is arranged vertically away from the resting plane, in particular lower or away from the resting plane in the surface normal, below or in the second half space. This is realized, for example, by arranging at least one corrugated plate.

[0022] In an alternative or additional refinement, the vibration device is preferably characterized in that at least one gas discharge device has at least one deflection surface, which is arranged movably together with the respective at least one gas discharge device and is always arranged in the lower or second half-space, regardless of the position of the respective at least one gas discharge device, and the upper end of the at least one deflection surface is arranged further away from the respective at least one discharge opening of the at least one respective gas discharge device than the lower end of the at least one deflection surface, and more preferably downstream of the at least one discharge opening of the respective gas discharge device in the discharge direction, whereby the gas flow is improved by being partially deflected and thus transported with a vertical component.

[0023] In an alternative or additional refinement, the vibration device is preferably characterized in that the pile ventilation device has at least two, more preferably at least three, more preferably at least four, even more preferably at least five gas discharge devices arranged at a distance from one another in the transverse direction. Preferably, these gas discharge devices each have one discharge opening or a number of discharge openings. More preferably, these discharge openings are also designed such that they extend vertically over an overall length of at least 15 mm, preferably at least 20 mm, more preferably at least 25 mm, even more preferably at least 35 mm, even more preferably at least 50 mm. The at least two, or at least three, or at least four, or at least five gas discharge devices can preferably be arranged at different positions relative to the pile support surface. As a result, the gas flow is introduced into the sheet pile in an optimized transverse direction and can be adapted to sheets of different widths, for example by deliberate control or partial switching off.

[0024] A method for operating a vibrating device is preferably proposed, in which a particularly roughly stacked sheet pile is placed on a pile placement device, the pile placement device is preferably pivoted about at least one pivot axis, more preferably about two pivot axes, the sheet pile is moved in a vibration process by at least one vibration drive, during the vibration process at least one gas or gas mixture, in particular air, is blown between the sheets of the sheet pile by a pile ventilation device, and during the vibration process at least one upper pile limiter is moved alternately up and down, so that a force is repeatedly applied to at least the uppermost sheets of the sheet pile, which limits the height of the sheet pile and makes it possible to introduce particularly a lot of air into the sheet pile, so that the sheets can be moved in a special way and then adjusted. In an alternative or additional refinement, the method is preferably characterized in that during the vibration step, at least one gas or gas mixture, in particular air, is additionally blown into the space between the lowermost sheet of the sheet pile and the pile placement device by means of a pile ventilation device.In an alternative or additional refinement, the method is preferably characterized in that before or during the vibration step, at least one gas discharge device is transferred from a lowered position to a ventilation position, and during or after the vibration step, the at least one gas discharge device is transferred from its ventilation position to a lowered position.This makes it easier to handle the sheet pile outside the vibration step, and nevertheless allows the device to be designed or operated in a space-saving manner.

[0027] The vibrating device 101 is preferably configured as a vibrating device 101 for placing the sheets 103 in a sheet pile 104, in particular as a vibrating device 101 for carrying out a vibration process for transforming a roughly stacked sheet pile 104 into a smoothly stacked sheet pile 104. The vibrating device 101 has at least one pile placement device 106 which is pivotably arranged. For example, the pile placement device 106 is pivotable about at least two pivot axes, which are preferably oriented perpendicular to one another. Such a first pivot axis extends, for example, in a first horizontal direction T, also called in particular the first conveying direction T. Such a second pivot axis extends, for example, in a second horizontal direction A, also called the transverse direction. The respective pivot angle is preferably adjustable, for example between 1° and 30°, preferably between 5° and 20°.

[0028] A rest plane 111 is determined by the pile placement device 106. By rest plane 111 is meant in particular the plane 111 which determines the lower end of the ideally cuboid-shaped sheet pile 104 located on the pile placement device 106. The position of the rest plane 111 relative to the pile placement device 106 is fixed, i.e. when the pile placement device 106 is pivoted, the rest plane 111 is correspondingly pivoted with it. The pile placement device 106 has, for example, a substantially pile support surface 107 which does not have to be flat but which, for example, has means for facilitating the sliding of the sheets 103 on the pile support surface 107. Such means are, for example, openings for the discharge of air and / or a surface structure with different height positions.

[0029] The resting plane 111 separates the upper half-space H1 from the lower half-space H2. The respective half-spaces H1;H2 are understood to be half-spaces H1;H2 in the mathematical sense. Independent of the pivot position of the pile resting device 106 and thus of the position of the resting plane 111 in space, a normal vector is associated with the resting plane 111 having a component oriented upwards in the vertical direction V. This normal vector extends from the resting plane 111 into the upper half-space H1.

[0030] The vibration device 101 has at least one first front stop 108, by means of which the pile-forming area 102 is limited and / or can be limited in the first conveying direction T. The pile-forming area 102 is preferably a spatial area 102 that is provided so as to be filled at least temporarily with the sheets 103 of the sheet pile 104 from the start of the vibration process until the end of this vibration process. The pile-forming area 102 is thus a spatial area 102 that the sheets may occupy at least temporarily during the vibration process, independent of their desired position at the end of the vibration process. In this vibration process, the sheet pile 104 is preferably changed from a roughly stacked sheet pile 104 to a smoothly stacked sheet pile 104. In particular, this means that the sheet pile 104 is in a roughly stacked state at the start of the vibration process and in a smoothly stacked state at the end of the vibration process. The pile-forming area 102 is preferably at least partially limited by components 106;108;109;116;117;118;141 of the vibrating device 101. In particular, these components 106;108;109;116;117;118;141 of the vibrating device 101 preferably cause the sheets 103 of the sheet pile 104 to remain in the pile-forming area 102 from the start of the vibration process to the end of the vibration process. These components 106;108;109;116;117;118;141 are, for example, the pile resting device 106 and / or at least one first front stop 107 and / or at least one side stop 109;141 and / or at least one upper pile limiter 116;117;118. The rest plane 111 preferably forms a lower limit of the pile-forming area 102. The pile-forming area 102 may depend, for example, on the format of the sheets 103, if, for example, two side stops 109; 141 are used or if an upper pile limiter 116; 117; 118 is positioned format-dependently. The pile-forming area 102 is preferably arranged in the upper or first half-space H1.Due to the pivoting ability of the pile placement device 106, the respective sheet pile 104 can be leaned against at least one front stop 108 and / or at least one side stop 109; 141. In this case, the pile-forming area 102 is limited in the same way in opposite directions by gravity, the corresponding boundaries of the pile-forming area 102 being determined, for example, by the shape of the respective roughly stacked sheet pile 104.

[0031] At least one front stop 108 is preferably arranged movable in the vertical direction V and / or in the direction of the normal vector of the rest plane 111, in particular arranged changeably between a transport position and a holding position. When the front stop 108 is arranged in the holding position, the front stop 108 preferably projects further into the upper or first half space H1 than when the front stop 108 is arranged in the transport position. Furthermore, at least one front stop 108 is preferably located completely outside the upper or first half space H1 when this first front stop 108 is arranged in the transport position. In this case, for example, a particularly smoothly stacked sheet pile 104 can be conveyed over the at least one front stop 108 arranged in its transport position.

[0032] The vibration device 101 has at least one first side stop 109. Preferably, the pile-forming area 102 is limited and / or can be limited in the transverse direction A by the at least one first side stop 109. The transverse direction A is preferably oriented orthogonally to the conveying direction T and / or orthogonally to the direction of the normal vector of the resting plane 111. Preferably, the vibration device 101 has at least one second side stop 141. Preferably, the pile-forming area 102 is limited and / or can be limited in the transverse direction A or in the opposite direction to the transverse direction A by the at least one second side stop 141. Preferably, the pile-forming area 102 is arranged between the at least one first side stop 109 and the at least one second side stop 141 with respect to the transverse direction A. At least one side stop 109;141 is preferably arranged movable in the vertical direction V and / or in the direction of the normal vector of the rest plane 111, in particular arranged changeably between a stop position and a pass position. When the side stop 109;141 is arranged in the stop position, the side stop 109;141 preferably extends further into the upper or first half space H1 than when the side stop 109;141 is arranged in the pass position. Furthermore, the respective side stop 109;141 is preferably located completely outside the upper or first half space H1 when the side stop 109;141 is arranged in the pass position. In this case, for example, the roughly stacked sheet pile 104 can be moved beyond the at least one side stop 109;141 arranged in its pass position into the pile forming area. At least one side stop 109; 141 is preferably arranged pivotably about an axis which is oriented in particular parallel to the vertical direction V and / or parallel to the normal vector of the rest plane 111. This allows, for example, an adaptation to a trapezoidal sheet 103 in the case of a relatively long side stop.

[0033] The vibration device 101 preferably has at least one vibration drive 122. The vibration drive 122 has, for example, a fixed part, which is for example designed as a stator or has a stator. The vibration drive 122 has, for example, a movable part, which is for example designed as a rotor or has a rotor. Preferably, at least one front stop 108 and / or at least one first side stop 109 and / or at least one second side stop 141, if present, are arranged in a connected manner to the movable part of the vibration drive 122. Preferably, the pile placement device 106 is arranged in a connected manner to the movable part of the vibration drive 122.

[0034] The vibration device 101 has a pile ventilation device 112, which is preferably configured as a rear blowing device 112. The pile ventilation device 112 has at least one gas discharge device 113, which can be arranged in different positions relative to the pile placement device 106 and / or the pile support surface 107. The pile forming area 102 is preferably arranged between the at least one gas discharge device 113 and the at least one front stop 108 with respect to the first conveying direction T. The at least one gas discharge device 113 is preferably different from the respective front stop 108 and the respective side stop 109;141. The at least one gas discharge device 113 is preferably arranged movably independent of the respective front stop 108 and the respective side stop 109;141.

[0035] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that at least one gas discharge device 113 is arranged to be movable between at least one respective lowered position and at least one respective venting position, in particular arranged to be movable in the vertical direction V. Preferably, at least one gas discharge device 113 is arranged at least partially in the upper or first half-space H1 in its respective at least one venting position, and at least one gas discharge device 113 is arranged completely in the lower or second half-space H2 in its respective at least one lowered position.

[0036] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the at least one gas discharge device 113 has a discharge opening 114 or a number of discharge openings 114, which are in particular configured as gas discharge openings 114 and are connected, for example, to a compressed air source. The one or more discharge openings 114 extend in the vertical direction V over at least 15 mm, preferably at least 20 mm, more preferably at least 25 mm, more preferably at least 35 mm, more preferably at least 50 mm. Preferably, each at least one discharge opening 114 extends in the respective ventilation position over at least 15 mm, more preferably at least 20 mm, more preferably at least 25 mm, more preferably at least 35 mm, more preferably at least 50 mm into the upper or first half-space H1 and / or beyond the rest plane 111.

[0037] For example, each outlet opening has a width of at least 0.5 mm, and more preferably at least 1 mm, in the transverse direction A. For example, each outlet opening has a width of at most 10 mm, and more preferably at most 5 mm, and even more preferably at most 2 mm, in the transverse direction A.

[0038] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the ejection direction B determined by the at least one gas ejection device 113 has at least one component oriented parallel to the first conveying direction T, and more preferably this ejection direction is oriented parallel to the first conveying direction T.

[0039] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that at least one gas discharge device 113 has at least two or at least three discharge openings 114 each, which are arranged one above the other with respect to the vertical direction V. In an alternative or additional refinement, the vibration device 101 is preferably characterized in that a plurality of gas discharge devices 113 have at least two or at least three discharge openings 114 each, which are arranged one above the other with respect to the vertical direction V. In an alternative or additional refinement, the vibration device 101 is preferably characterized in that all gas discharge devices 113 have at least two or at least three discharge openings 114 each, which are arranged one above the other with respect to the vertical direction V.

[0040] Preferably, all the discharge openings 114 of each gas discharge device 113, and more preferably all the discharge openings 114 of all the gas discharge devices 113, are arranged in a line-technical connection to one common gas supply line 142. In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the narrowest point of the lowermost gas supply line 119 leading to the lowest one of the plurality of discharge openings 114 of each gas discharge device 113 has a larger flow-through cross-sectional area than the narrowest point of the uppermost gas supply line 121 leading to the uppermost one of the plurality of discharge openings 114 of this respective gas discharge device 113. This ensures that the gas or gas mixture is discharged at a higher pressure from the lowermost discharge opening 114 than from the uppermost discharge opening 114, despite being connected to the common gas supply line 142. The amount of gas introduced into the sheet pile 104 can thus be influenced depending on the height position. For example, corresponding cross-sectional areas can be adapted, in particular by inserting corresponding components, in particular respective throttles, with correspondingly sized openings.

[0041] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the at least one gas ejection device 113 is arranged separately from the movable parts of the vibration drive device 122 and / or the pile placement device 106 is arranged so as to be pivotable independently of the at least one gas ejection device 113.

[0042] Preferably, the pile placement device 106 has at least one receiving opening 123, more preferably a plurality of receiving openings 123, which are even more preferably arranged next to each other and spaced apart from each other in the lateral direction A. Each at least one gas discharge device 113 is preferably arranged to be movable at least partially through the respective receiving opening 123, in particular to be transported between at least one respective lowered position and at least one respective ventilation position. The at least one receiving opening 123 preferably extends in a sliding direction S, which is preferably oriented parallel to the discharge direction B and / or the first conveying direction T.

[0043] Preferably, the at least one gas discharge device 113 is movable in the sliding direction S while projecting through the respective receiving opening 123 into the upper half space H1. Preferably, the at least one gas discharge device 113 is arranged so that it can be moved in the sliding direction S between at least one respective lowered position and at least one respective ventilation position into different longitudinal positions, in particular adapted to the format. The at least one gas discharge device 113 is thus preferably arranged so that it can be freely moved in the respective receiving opening 123 both in the vertical direction V and in the sliding direction S. This allows the corresponding sheet pile 104 to be optimally processed by the vibration device 101 in accordance with the respective format of the sheets 103 and / or the respective pile height.

[0044] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that at its end 128, at which the at least one receiving opening 123 is located opposite the respective discharge opening 114 in its sliding direction S and / or in the discharge direction B and / or in the first conveying direction T, it has a respective gas guide surface 124, the upper end 126 of which is arranged further from the respective discharge opening 114 than the lower end 127 of this gas guide surface 124. Such a gas guide surface 124 is, for example, a flat, obliquely oriented surface, so that the gas moving parallel to the rest surface 111 can be deflected upwards in order to lift the lowermost sheet 103 of the corresponding sheet pile 104.

[0045] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the upper surface 129 of the pile placement device 106 has at least one resting area 131 and at least one gas guide area 132. Preferably, the at least one resting area 131 and the resting plane 111 are in tangential contact with each other or the at least one resting area 131 determines the resting plane 111. Preferably, the at least one gas guide area 132 is arranged at a distance from the resting plane 111 in the vertical direction V, in particular lower and / or at a distance from the resting plane 111 in the direction of the normal vector of the resting plane 111 and / or in the lower or second half space H2. For example, the pile placement device 106 has a surface formed as a corrugated plate or has a flat surface with air holes, to which, for example, lowerable and / or spherical closures are assigned.

[0046] In an alternative or additional refinement, the vibration device 101 is preferably characterized in that the at least one gas discharge device 113 has at least one deflection surface 133 which is arranged movably together with the respective at least one gas discharge device 113 and which, independent of the position of the respective at least one gas discharge device 113, is always arranged in the lower or second half-space H2, the upper end 134 of the deflection surface 133 being preferably arranged further away from the respective at least one discharge opening 114 of the at least one respective gas discharge device 113 than its lower end 136, at least in relation to the discharge direction B. In particular, the at least one deflection surface 133 is arranged downstream of the at least one discharge opening 114 of the respective gas discharge device 113, as viewed in the discharge direction B. Such a deflection surface 133 makes it possible to create an upwardly directed gas flow in the region of the beginning of the sheet pile 104, which gas flow advantageously guides the gas into the gaps between the individual sheets 103 and / or between the lowermost sheet 103 of this sheet pile 104 and the pile placement device 106.

[0047] In an alternative or additional refinement, the vibration device 101 preferably has a pile ventilation device 112 having at least two, more preferably at least three, even more preferably at least four, even more preferably at least five gas discharge devices 113 arranged at a distance from one another in the transverse direction A. The at least two and / or at least three and / or at least four and / or at least five gas discharge devices 113 preferably each have one discharge opening 114 or a number of discharge openings 114. Further preferably, the one or more discharge openings 114 extend in the vertical direction V over an overall length of at least 15 mm, more preferably at least 20 mm, even more preferably at least 25 mm, even more preferably at least 35 mm, even more preferably at least 50 mm. Preferably, these at least two and / or at least three and / or at least four and / or at least five gas discharge devices 113 can be arranged at different positions relative to the pile placement device 106 and / or the pile support surface 107, respectively.

[0048] In an alternative or additional refinement, the vibrating device 101 preferably has at least one upper pile limiter 116; 117; 118. The at least one upper pile limiter 116; 117; 118 is preferably arranged and / or can be arranged at least temporarily above the pile-forming area 102. In an alternative or additional refinement, the at least one vibrating device 101 is preferably characterized in that the at least one upper pile limiter 116; 117; 118 limits the pile-forming area 102 in an upward direction. The at least one upper pile limiter 116; 117; 118 preferably serves to prevent the sheets 103 of the sheet pile 104 from being lifted too far upwards. This ensures that even if the sheet pile 104 is significantly loosened by the blown-in air, a smoothly stacked sheet pile 104 can be formed and that the sheets 103 are not swept away too far.

[0049] Preferably, the at least one upper pile limiter 116; 117; 118 is movable between at least one upper limiting position and at least one lower limiting position, thereby allowing the sheet pile 104 to be processed dynamically. In the sheet pile 104 loosened by the gas flow, a movement is introduced by the movable at least one upper pile limiter 116; 117; 118, in particular in addition to the vibrations generated by the at least one vibration drive 122. This, on the one hand, expels gas or a gas mixture, in particular air, from the sheet pile 104 and, on the other hand, increases the mobility of the sheets 103, so that the sheets 103 can slide towards the at least one front stop device 108 and the at least one side stop 109; 141 and thus allows the formation of a smoothly stacked sheet pile 104.

[0050] At least one upper pile limiter 116; 117; 118 preferably limits the pile-forming area 102 both in its upper limiting position and also in its lower limiting position, i.e. the extension of the pile-forming area 102 is preferably dynamic. Preferably, the at least one upper pile limiter 116; 117; 118 is arranged movably between the respective at least one upper limiting position and the respective at least one lower limiting position, independently of the at least one first front stop device 108 and independently of the at least one first lateral stop 109.

[0051] The vibrating device 101 preferably has a number of upper pile limiting portions 116; 117; 118. In an alternative or additional refinement, the vibrating device 101 is preferably characterized in that it has at least one inner upper pile limiting portion 116 which limits the pile-forming area 102 upwards in at least one inner area 137. This at least one inner area 137 is spaced apart from each edge 138 of the pile-forming area 102 by at least 10 mm, more preferably at least 20 mm, even more preferably at least 50 mm, even more preferably at least 100 mm, even more preferably at least 200 mm in each horizontal direction A; B; S; T. There may also be inner areas 137 in which the inner upper pile limiting portion 116 does not limit the pile-forming area 102 directly upwards. Preferably, the at least one inner upper pile limiter 116 is arranged to be movable with respect to the horizontal directions B, S, T. For example, the at least one inner upper pile limiter 116 is arranged to be movable between at least one stop position and at least one use position, in particular with respect to the conveying direction T. Preferably, the at least one inner upper pile limiter 116 can be arranged in different use positions that are adapted with respect to at least one horizontal direction B, S, T. This allows for adaptation to sheets 103 of different formats. For example, the at least one inner upper pile limiter 116 is formed as a straightening element 116, in particular as a straightening roller 116. In addition to its function as an upper pile limiter 116, the straightening roller 116 serves to apply a force from above to the sheet pile 104 at the end of the vibration process and is moved linearly in the process. This also makes it possible for air contained between the sheets 103 in the sheet pile 104 to be expelled from the sheet pile 104, thereby stabilizing the sheet pile 104. Alternatively to the smoothing roller 116, components that slide without rolling can also be used.

[0052] The vibrating device 101 preferably has a plurality of upper pile limiters 116; 117; 118. In an alternative or additional refinement, the vibrating device 101 is preferably characterized in that the vibrating device 101 has at least one upper pile limiter 117; 118 formed as an edge limiter 117; 118, which limits the pile forming area 102 in at least one edge area 139 towards the top. At least one upper pile limiting portion 117;118 formed as an edge limiting portion 117;118 limits the pile-forming area 102 upwards in at least one edge region 139, which is spaced apart from an edge 138 of the pile-forming area 102 in at least one horizontal direction A;B;S;T by at most 50 mm, preferably at most 20 mm, more preferably at most 10 mm, more preferably at most 5 mm. This distance from the edge should be measured, for example, in the horizontal directions A;B. In this case, an edge region 139 may also be provided in which the edge limiting portion 116 does not limit the pile-forming area 102 directly upwards.

[0053] For example, the upper pile limiter 116;117;118 can be lowered at least partially such that it is arranged only in the lower or second half-space H2. In this case, the sheet pile 104 can be transported unhindered beyond the upper pile limiter. Alternatively, it is possible to remove the upper pile limiter 116;117;118 from the defined transport path of the sheet pile 104 in an upward direction. For example, at least one front edge limiter 118 is arranged, in particular in the region of the front stop 108, and / or at least one lateral edge limiter 117 is arranged, in particular in the region of the lateral stops 109;141, and / or at least two lateral edge limiters 117 are arranged, in particular on both sides of the pile-molding area 102, in relation to the transverse direction A, in particular in the region of at least one or preferably each one lateral stopper 109;141.

[0054] The vibrating device 101 is suitable for a preferred method of operating the vibrating device 101. In such a method, for example, a loosely stacked sheet pile 104 is placed on the pile placement device 106. In one embodiment, the pile placement device 106 is pivoted about at least one pivot axis, more preferably about two pivot axes. Preferably, during the vibration process, the sheet pile 104 is set in motion by at least one vibration drive 122. During the vibration process, at least one gas or gas mixture, in particular air, is blown between the sheets 103 of the sheet pile 104 by the pile ventilation device 112. Preferably, during the vibration process, at least one gas or gas mixture, in particular air, is additionally blown between the lowermost sheet 103 of the sheet pile 104 and the pile placement device 106 by the pile ventilation device 112. Preferably, during the vibration step, at least one upper pile limiter 116; 117; 118 is moved alternately up and down, so that at least the uppermost sheet 103 of the sheet pile 104 is subjected to a repeated force. In an alternative or additional refinement, the method is preferably characterized in that before or during the vibration step, at least one gas discharge device 113 is transferred from a lowered position to a ventilation position and during or after the vibration step, the at least one gas discharge device 113 is transferred from its ventilation position to a lowered position. Preferably, for the method, a vibration device 101 is used in which the pile ventilation device 112 is configured as a rear blowing device 112 and the pile forming area 102 is arranged between the at least one gas discharge device 113 and the at least one front stop 108 in relation to the first conveying direction T.
