[0012] The invention is based on the object of creating a vibrating device.

[0013] The object is achieved according to the invention by the features of claim 1 and the features of claim 2.

[0014] A jogging device is designed, for example, for arranging sheets in a stack of sheets and / or for carrying out a jogging process to convert a roughly stacked stack of sheets into a smoothly stacked stack of sheets. The jogging device has at least one pivotably arranged stack support device, by means of which a support plane is defined, the position of which is fixed relative to the stack support device. The support plane preferably separates an upper half-space from a lower half-space. The jogging device has at least one first front stop, by means of which a stack forming region is and / or can be delimited in a first transport direction. The transport direction is therefore preferably the direction that points from the stack forming region to the front stop, more preferably orthogonal to a boundary surface of the stack forming region, which boundary surface is defined by the front stop.The vibrating device has at least one first lateral stop, by which the stack forming area is delimited and / or can be delimited in a transverse direction, in particular orthogonal to the transport direction. The support plane preferably forms a lower boundary of the stack forming area. The vibrating device has a stack ventilation device, designed in particular as a rear blowing device. The stack ventilation device has at least one gas ejection device, which can be arranged in different positions relative to the stack support device or a stack support surface. The stack forming area is preferably arranged between the at least one gas ejection device and the at least one front stop with respect to the first transport direction.In a preferred development, the at least one gas ejection device is arranged so as to be transferable between at least one respective lowered position and at least one respective ventilation position, in particular transferable in the vertical direction. Preferably, the at least one gas ejection device, in its respective at least one ventilation position, is arranged at least partially in the upper or first half-space. Preferably, the at least one gas ejection device, in its respective at least one lowered position, is arranged entirely in the lower or second half-space, i.e., in particular, is not arranged in the upper or first half-space.

[0015] This offers the advantage that all sheets in a stack can be influenced by the blowing device, yet the blowing device cannot collide with the stack support device. This is preferably possible even when the sheets are shorter than a maximum format, especially if appropriate receiving openings are provided. This still ensures maximum mobility of the sheets during transport.

[0016] In an alternative or additional development, the vibrating device is preferably characterized in that the at least one gas ejection device has one ejection opening or gas ejection openings or several ejection openings, and these one or more ejection openings extend over a total of at least 15 mm, preferably at least 20 mm, more preferably at least 25 mm, even more preferably at least 35 mm, and even more preferably at least 50 mm in the vertical direction. This allows a particularly large portion of the sheet stack to be loosened simultaneously. The maximum height of a stationary sheet stack is preferably at most 55 mm, more preferably at most 30 mm.

[0017] In an alternative or additional development, the vibrating device is preferably characterized in that the vibrating device has at least one upper stack limiter, which is and / or can be arranged at least temporarily above the stack forming area and limits the stack forming area at the top. Particularly large gas volumes can then be blown into the sheet stack without destroying it. This loosens the sheet stack to a particular extent and allows for particularly efficient smoothing of the sheet stack. In an alternative or additional development, the vibrating device is preferably characterized in that the at least one upper stack limiter is movable between at least one upper limiting position and at least one lower limiting position.In particular, the at least upper stack limiter is arranged further up in its at least one upper limiting position relative to the vertical direction than in the at least one lower limiting position.

[0018] In an alternative or additional development, the vibrating device is preferably characterized in that the vibrating device has at least one inner upper stack limiter, which delimits the stack forming area upwards in at least one inner region, which is spaced at least 10 mm, preferably at least 20 mm, more preferably at least 50 mm, even more preferably at least 100 mm, and even more preferably at least 200 mm from each edge of the stack forming area in any horizontal direction. A central region can then be delimited upwards independently of edge regions, which allows for optimized operation of the at least one upper stack limiter.In an alternative or additional development, the vibrating device is preferably characterized in that the vibrating device has at least one upper stack limiter designed as an edge limiter, which limits the stack forming area upwards in at least one edge area, which is spaced from an edge of the stack forming area by at most 50 mm, preferably at most 20 mm, more preferably at most 10 mm and even more preferably at most 5 mm in at least one horizontal direction.

[0019] In an alternative or additional development, the vibrating device is preferably characterized in that, with respect to the first transport direction, the stack forming region is arranged between the at least one gas ejection device and the at least one front stop. In an alternative or additional development, the vibrating device is preferably characterized in that an ejection direction determined by the at least one gas ejection device has at least one component that is oriented parallel to the first transport direction. The ejection direction is preferably parallel to the first transport direction. The gas ejection device can then always be used, regardless of the width of the sheets. It is also advantageous to blow gas or air into the sheet stack from behind, because then one of two opposite side stops can be used optionally.In addition, the sheets are then subjected to a force towards the front stop not only by the inclined position but also by the gas or gas mixture blown in.

[0020] In an alternative or additional development, the vibrating device is preferably characterized in that the at least one, preferably several, and more preferably each, gas ejection device has at least two or at least three ejection openings arranged one above the other in the vertical direction. Different regions of the sheet stack can then be subjected to different, in particular adapted, pressures or volume flows relative to the vertical direction.In an alternative or additional development, the vibrating device is preferably characterized in that a narrowest point of a lowest gas supply line, which leads to a lowest of the plurality of discharge openings of a respective gas discharge device, has a larger flow-through cross-sectional area than a narrowest point of an uppermost gas supply line, which leads to a topmost of the plurality of discharge openings of this respective gas discharge device.

[0021] In an alternative or additional development, the vibrating device is preferably characterized in that the at least one gas ejection device is arranged decoupled from a movable part of a vibrating drive and / or in that the stack support device is arranged pivotably independently of the at least one gas ejection device. As a result, the vibrating device is designed to be particularly robust with respect to the at least one gas ejection device. The stack support device is preferably connected to a movable part of a vibrating drive.In an alternative or additional development, the vibrating device is preferably characterized in that the stack support device has at least one receiving opening and, in particular, a plurality of receiving openings, and in that the at least one gas ejection device is arranged to be movable at least partially through a respective receiving opening in order to be transferred between the at least one respective lowering position and the at least one respective ventilation position. This enables an optimized, for example, format-adapted arrangement and alignment of the at least one gas ejection device with a simultaneous optimized vibrating movement.In an alternative or additional development, the vibrating device is preferably characterized in that the at least one receiving opening extends in a displacement direction that is preferably oriented parallel to the ejection direction and / or the first transport direction, and in that the at least one gas ejection device is movable in the displacement direction while protruding through the respective receiving opening into the upper half-space and / or is arranged so as to be transferable at different longitudinal positions between at least one respective lowering position and at least one respective ventilation position with respect to the displacement direction. For example, the at least one receiving opening extends in a displacement direction over a length of at least 20 mm, preferably at least 50 mm, more preferably at least 100 mm, and even more preferably at least 200 mm.

[0022] In an alternative or additional development, the vibrating device is preferably characterized in that the at least one receiving opening has, at its end opposite the respective ejection opening in the displacement direction and / or the ejection direction and / or the first transport direction, a respective gas guide surface, the upper end of which is arranged farther away from the respective ejection opening than its lower end. This transports gas beneath a lowermost sheet and improves its mobility.In an alternative or additional development, the vibrating device is preferably characterized in that an upper surface of the stack support device has at least one support area and at least one gas conducting area, and in that the at least one support area and the support plane touch each other tangentially, and in that the at least one gas conducting area is arranged in the lower or second half-space at a distance from the support plane in the vertical direction, in particular lower or at a distance from the support plane relative to a surface normal. This is achieved, for example, by arranging at least one checkered plate.

[0023] In an alternative or additional development, the vibrating device is preferably characterized in that the at least one gas ejection device has at least one deflection surface which is arranged to be movable together with the respective at least one gas ejection device and which, regardless of the position of the respective at least one gas ejection device, is always arranged in the lower or second half-space and whose upper end is arranged further away from the respective at least one ejection opening of the at least one respective gas ejection device than its lower end and which, viewed in the ejection direction, is further preferably arranged downstream of the at least one ejection opening of the respective gas ejection device. This improves the gas flow by deflecting a portion and then transporting it with a component in the vertical direction.

[0024] In an alternative or additional development, the vibrating device is preferably characterized in that the stack ventilation device has at least two, more preferably at least three, even more preferably at least four, and even more preferably at least five gas ejection devices, which are arranged spaced apart from one another in the transverse direction. These gas ejection devices preferably each have one or more ejection openings. More preferably, these are also designed such that they extend a total of at least 15 mm, preferably at least 20 mm, more preferably at least 25 mm, even more preferably at least 35 mm, and even more preferably at least 50 mm in the vertical direction. These at least two or at least three or at least four or at least five gas ejection devices can preferably each be arranged in different positions relative to the stack support surface.This means that the gas flow is introduced into the sheet stack in an optimized manner in relation to the transverse direction and can be adapted to sheets of different widths, for example by targeted control or partial shutdown.

[0025] A method for operating a vibrating device is preferred, wherein a particularly coarsely stacked stack of sheets is arranged on a stack support device and wherein the stack support device is preferably pivoted about at least one pivot axis, more preferably two pivot axes and wherein, in a vibrating process, the stack of sheets is set in motion by means of at least one vibrating drive and wherein, during the vibrating process, at least one gas or gas mixture, in particular air, is blown in between sheets of this stack of sheets by means of a stack ventilation device and wherein, during the vibrating process, at least one upper stack limiter is moved alternately up and down and, as a result, a force is repeatedly exerted on at least one uppermost sheet of the stack of sheets.This limits the height of the sheet stack and allows a particularly large amount of air to be introduced into the sheet stack, whereby the sheets can be mobilized and then aligned in a special way. In an alternative or additional development, the method is preferably characterized in that during the jogging process, by means of the stack ventilation device, at least one gas or gas mixture, in particular air, is additionally blown between a bottommost sheet of this sheet stack and the stack support device. In an alternative or additional development, the method is preferably characterized in that before or during the jogging process, at least one gas ejection device is transferred from a lowering position to a ventilation position and that during the jogging process or after the jogging process, this at least one gas ejection device is transferred from its ventilation position to the lowering position.This makes it easier to handle the stack of sheets outside of the jogging process, and the device can still be designed and operated in a space-saving manner.

[0028] A jogging device 101 is preferably designed as a jogging device 101 for arranging sheets 103 in a sheet stack 104, in particular as a jogging device 101 for carrying out a jogging process for transferring a roughly stacked sheet stack 104 into a smoothly stacked sheet stack 104. The jogging device 101 has at least one pivotably arranged stack support device 106. For example, this stack support device 106 is pivotable about at least two pivot axes, which are preferably oriented orthogonally to one another. A first such pivot axis extends, for example, in a first horizontal direction T, which is also referred to as the first transport direction T. A second such pivot axis extends, for example, in a second horizontal direction A, which is also referred to as the transverse direction.A respective swivel angle is preferably adjustable and is, for example, between 1° and 30°, preferably between 5° and 20°.

[0029] A support plane 111 is defined by the stack support device 106. A support plane 111 is understood in particular to be a plane 111 that defines the lower end of an ideally cuboid-shaped stack of sheets 104 located on the stack support device 106. The position of the support plane 111 relative to the stack support device 106 is fixed. This means that when the stack support device 106 is pivoted, the support plane 111 is pivoted accordingly. The stack support device 106 essentially has, for example, a stack support surface 107, which, however, does not have to be flat, but rather has, for example, means that facilitate the displacement of sheets 103 on the stack support surface 107. Such means are, for example, openings for expelling air and / or a surface structure with different heights.

[0030] The support plane 111 separates an upper half-space H1 from a lower half-space H2. Each half-space H1; H2 is understood to be a half-space H1; H2 in the mathematical sense. Regardless of the pivoting position of the stack support device 106 and thus the position of the support plane 111 in space, a normal vector can be assigned to the support plane 111, which has a component oriented upward in the vertical direction V. This normal vector points from the support plane 111 into the upper half-space H1.

[0031] The jogging device 101 has at least one first front stop 108, by which a stack forming area 102 is delimited and / or can be delimited in the first transport direction T. The stack forming area 102 is preferably the spatial area 102 that is intended to be at least temporarily filled by the sheets 103 of a sheet stack 104 from the start of a jogging process to the end of this jogging process. The stack forming area 102 is therefore the spatial area 102 that the sheets may at least temporarily occupy during the jogging process, regardless of their desired position at the end of the jogging process. In this jogging process, the sheet stack 104 is preferably transferred from a roughly stacked sheet stack 104 to a smoothly stacked sheet stack 104.In particular, this means that the sheet stack 104 is in a roughly stacked state at the beginning of the jogging process and in a smoothly stacked state at the end of the jogging process. The stack forming area 102 is preferably at least partially delimited by components 106; 108; 109; 116; 117; 118; 141 of the jogging device 101. In particular, these components 106; 108; 109; 116; 117; 118; 141 of the jogging device 101 preferably ensure that the sheets 103 of the sheet stack 104 remain in the stack forming area 102 from the beginning of the jogging process until the end of the jogging process. These components 106; 108; 109; 116; 117; 118; 141 are, for example, the stack support device 106 and / or the at least one first front stop 107 and / or at least one side stop 109; 141 and / or at least one upper stack limiter 116; 117; 118. The support plane 111 preferably forms a lower boundary of the stack forming area 102.The stack forming area 102 can, for example, depend on the format of the sheets 103, for example, if two side stops 109; 141 are used or upper stack limiters 116; 117; 118 are positioned depending on the format. The stack forming area 102 is preferably arranged in the upper or first half-space H1. Due to the pivotability of the stack support device 106, the respective sheet stack 104 can be leaned against the at least one front stop 108 and / or the at least one side stop 109; 141. Then, the stack forming area 102 is also limited in the opposite direction due to gravity, and its corresponding boundary is determined, for example, by the shape of the respective roughly stacked sheet stack 104.

[0032] The at least one front stop 108 is preferably arranged to be movable with respect to the vertical direction V and / or with respect to a direction of the normal vector of the support plane 111 and, in particular, is arranged to be interchangeable between a transfer position and a retention position. When the front stop 108 is arranged in the retention position, it preferably projects further into the upper or first half-space H1 than when the front stop 108 is arranged in the transfer position. More preferably, the at least one front stop 108 is located completely outside the upper or first half-space H1 when it is arranged in its transfer position. Then, for example, a stack of sheets 104, in particular one that is stacked smoothly, can be transported away over the at least one front stop 108 arranged in its transfer position.

[0033] The vibrating device 101 has at least one first side stop 109.

[0034] The stack forming area 102 is delimited and / or delimitable in the transverse direction A by the at least one first lateral stop 109. The transverse direction A is preferably oriented orthogonal to the transport direction T and / or orthogonal to the direction of the normal vector of the support plane 111. The vibrating device 101 preferably has at least one second lateral stop 141. The stack forming area 102 is preferably delimited and / or delimitable in or counter to the transverse direction A by the at least one second lateral stop 141. The stack forming area 102 is preferably arranged between the at least one first lateral stop 109 and the at least one second lateral stop 141 with respect to the transverse direction A.The at least one side stop 109; 141 is preferably arranged to be movable with respect to the vertical direction V and / or with respect to a direction of the normal vector of the support plane 111 and, in particular, is arranged to be interchangeable between a stop position and a passing position. When the side stop 109; 141 is arranged in the stop position, it preferably projects further into the upper or first half-space H1 than when the side stop 109; 141 is arranged in the passing position. More preferably, the respective side stop 109; 141 is located completely outside the upper or first half-space H1 when it is arranged in its passing position. Then, for example, a roughly stacked sheet stack 104 can be moved over the at least one side stop 109; 141 arranged in its passing position into the stack forming area.The at least one side stop 109; 141 is preferably pivotably arranged, in particular about an axis oriented parallel to the vertical direction V and / or parallel to the normal vector of the support plane 111. This allows adaptation to trapezoidal arches 103, for example, in the case of relatively long side stops.

[0035] The vibrating device 101 preferably has at least one vibrating drive 122. This vibrating drive 122 has, for example, a stationary part, which is designed, for example, as a stator or has a stator. This vibrating drive 122 has, for example, a movable part, which is designed, for example, as a rotor or has a rotor. Preferably, the at least one front stop 108 and / or the at least one first side stop 109 and / or, if present, the at least one second side stop 141 are arranged connected to the movable part of the vibrating drive 122. Preferably, the stack support device 106 is arranged connected to the movable part of the vibrating drive 122.

[0036] The vibrating device 101 has a stack ventilation device 112. This stack ventilation device 112 is preferably designed as a rear blowing device 112. The stack ventilation device 112 has at least one gas ejection device 113, which can be arranged in different positions relative to the stack support device 106 and / or the stack support surface 107. The stack forming region 102 is preferably arranged between the at least one gas ejection device 113 and the at least one front stop 108 with respect to the first transport direction T. The at least one gas ejection device 113 is different from each front stop 108 and each side stop 109; 141. The at least one gas ejection device 113 is preferably arranged to be movable independently of each front stop 108 and each side stop 109; 141.

[0037] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one gas ejection device 113 is arranged so as to be transferable between at least one respective lowering position and at least one respective ventilation position, in particular in the vertical direction V. Preferably, the at least one gas ejection device 113 in its respective at least one ventilation position is arranged at least partially in the upper or first half-space H1 and the at least one gas ejection device 113 in its respective at least one lowering position is arranged completely in the lower or second half-space H2.

[0038] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one gas ejection device 113 each has one or more ejection openings 114. This at least one ejection opening 114 is designed in particular as a gas ejection opening 114 and is connected, for example, to a compressed air source. This one or more ejection openings 114 extend(s) over a total of at least 15 mm in the vertical direction V, more preferably over at least 20 mm, even more preferably over at least 25 mm, even more preferably over at least 35 mm, and even more preferably over at least 50 mm.Preferably, the respective at least one ejection opening 114 in the respective ventilation position extends over at least 15 mm into the upper or first half-space H1 and / or beyond the support plane 111, more preferably over at least 20 mm, even more preferably over at least 25 mm, even more preferably over at least 35 mm and even more preferably over at least 50 mm.

[0039] For example, the respective ejection openings are at least 0.5 mm wide, more preferably at least 1 mm, relative to the transverse direction A. For example, the respective ejection openings are at most 10 mm wide, more preferably at most 5 mm, and even more preferably at most 2 mm, relative to the transverse direction A.

[0040] In an alternative or additional development, the vibrating device 101 is preferably characterized in that an ejection direction B defined by the at least one gas ejection device 113 has at least one component which is oriented parallel to the first transport direction T and further preferably that this ejection direction is oriented parallel to the first transport direction T.

[0041] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one gas ejection device 113 each has at least two or at least three ejection openings 114 that are arranged one above the other with respect to the vertical direction V. In an alternative or additional development, the vibrating device 101 is preferably characterized in that a plurality of gas ejection devices 113 each have at least two or at least three ejection openings 114 that are arranged one above the other with respect to the vertical direction V. In an alternative or additional development, the vibrating device 101 is preferably characterized in that all gas ejection devices 113 each have at least two or at least three ejection openings 114 that are arranged one above the other with respect to the vertical direction V.

[0042] Preferably, all discharge openings 114 of a respective gas discharge device 113, and more preferably, all discharge openings 114 of all gas discharge devices 113, are arranged to be connected to a common gas supply line 142. In an alternative or additional development, the vibrating device 101 is preferably characterized in that a narrowest point of a lowermost gas supply line 119, which leads to a lowermost of the plurality of discharge openings 114 of a respective gas discharge device 113, has a larger flow-through cross-sectional area than a narrowest point of an uppermost gas supply line 121, which leads to a topmost of the plurality of discharge openings 114 of this respective gas discharge device 113.This ensures that, despite the connection to the common gas supply line 142, gas or gas mixture is ejected from the lowest ejection opening 114 at a higher pressure than from the uppermost ejection opening 114. Thus, the amount of gas introduced into the sheet stack 104 can be influenced depending on the altitude. For example, the corresponding cross-sectional areas can be adjusted, in particular by inserting a corresponding component with a correspondingly large opening, in particular a respective aperture.

[0043] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one gas ejection device 113 is arranged decoupled from a movable part of a vibrating drive 122 and / or in that the stack support device 106 is arranged pivotably independently of the at least one gas ejection device 113.

[0044] The stack support device 106 preferably has at least one receiving opening 123, more preferably a plurality of receiving openings 123, which are even more preferably arranged next to one another and spaced apart from one another in the transverse direction A. The respective at least one gas ejection device 113 is preferably arranged to be movable at least partially through a respective receiving opening 123, in particular in order to be transferred between the at least one respective lowering position and the at least one respective ventilation position. The at least one receiving opening 123 preferably extends in a displacement direction S. This displacement direction S is preferably oriented parallel to the ejection direction B and / or the first transport direction T.

[0045] Preferably, the at least one gas ejection device 113 is movable in the displacement direction S while protruding through the respective receiving opening 123 into the upper half-space H1. Preferably, the at least one gas ejection device 113 is arranged so as to be transferable, relative to the displacement direction S, at different, in particular format-adapted, longitudinal positions between at least one respective lowering position and at least one respective ventilation position. The at least one gas ejection device 113 is therefore preferably arranged so as to be freely movable within the respective receiving opening 123 both with respect to the vertical direction V and with respect to the displacement direction S. In this way, corresponding sheet stacks 104 can be processed in an optimized manner by means of the jogging device 101, adapted to a respective format of the sheets 103 and / or to a respective stack height.

[0046] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one receiving opening 123 has, at its end 128 opposite the respective ejection opening 114 in the displacement direction S and / or the ejection direction B and / or the first transport direction T, a respective gas guide surface 124, the upper end 126 of which is arranged further away from the respective ejection opening 114 than its lower end 127. An example of such a gas guide surface 124 is an inherently flat, obliquely oriented surface. As a result, gas moving parallel to the support plane 111 can be redirected upwards in order to lift a bottommost sheet 103 of a corresponding sheet stack 104.

[0047] In an alternative or additional development, the vibrating device 101 is preferably characterized in that an upper surface 129 of the stack support device 106 has at least one support region 131 and at least one gas conducting region 132. Preferably, the at least one support region 131 and the support plane 111 touch one another tangentially, or the at least one support region 131 defines the support plane 111. Preferably, the at least one gas conducting region 132 is arranged at a distance from the support plane 111 in the vertical direction V, in particular lower and / or distant from the support plane 111 in the direction of the normal vector of the support plane 111 and / or in the lower or second half-space H2. For example, the stack support device 106 is designed as a checkered plate on its surface or has a flat surface with air holes, to which, for example, lowerable and / or spherical closures are assigned.

[0048] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one gas ejection device 113 has at least one deflection surface 133 which is arranged to be movable together with the respective at least one gas ejection device 113 and which, regardless of the position of the respective at least one gas ejection device 113, is always arranged in the lower or second half-space H2 and whose upper end 134 is arranged further away from the respective at least one ejection opening 114 of the at least one respective gas ejection device 113 than its lower end 136, at least with respect to the ejection direction B. In particular, this at least one deflection surface 133 is arranged after the at least one ejection opening 114 of the respective gas ejection device 113, as seen in the ejection direction B.Such a deflection surface 133 makes it possible to generate an upwardly directed gas flow in the region of a beginning of a sheet stack 104, which advantageously directs the gas into spaces between individual sheets 103 and / or between a bottommost sheet 103 of this sheet stack 104 and the stack support device 106.

[0049] In an alternative or additional development, the vibrating device 101 is preferably characterized in that the stack ventilation device 112 has at least two, more preferably at least three, even more preferably at least four, and even more preferably at least five gas ejection devices 113, which are arranged spaced apart from one another in the transverse direction A. These at least two and / or at least three and / or at least four and / or at least five gas ejection devices 113 preferably each have one or more ejection openings 114. More preferably, these one or more ejection openings 114 extend in total over at least 15 mm, more preferably at least 20 mm, even more preferably at least 25 mm, even more preferably at least 35 mm, and even more preferably at least 50 mm in the vertical direction V.Preferably, these at least two and / or at least three and / or at least four and / or at least five gas ejection devices 113 can each be arranged in different positions relative to the stack support device 106 and / or the stack support surface 107.

[0050] In an alternative or additional development, the vibrating device 101 preferably has at least one upper stack limiter 116; 117; 118. The at least one upper stack limiter 116; 117; 118 is preferably arranged and / or can be arranged at least temporarily above the stack forming area 102. In an alternative or additional development, the at least one vibrating device 101 is preferably characterized in that the at least one upper stack limiter 116; 117; 118 delimits the stack forming area 102 at the top. The at least one upper stack limiter 116; 117; 118 preferably serves to prevent sheets 103 of the sheet stack 104 from lifting too far upwards. This ensures that a smoothly stacked sheet stack 104 can be produced and that sheets 103 do not drift too far, even if the sheet stack 104 is greatly loosened by blown-in air.

[0051] Preferably, the at least one upper stack limiter 116; 117; 118 is movable between at least one upper limiting position and at least one lower limiting position. This allows the sheet stack 104 to be processed dynamically. The at least one movable upper stack limiter 116; 117; 118 introduces movements into the sheet stack 104, which has been loosened by a gas stream, in particular in addition to the shaking movements generated by the at least one shaking drive 122. This, on the one hand, expels the gas or gas mixture, in particular the air, from the sheet stack 104 and, on the other hand, increases the mobility of the sheets 103, so that they can slide against the at least one front stop 108 and the at least one side stop 109; 141, thus producing a smoothly stacked sheet stack 104.

[0052] The at least one upper stack limiter 116; 117; 118 preferably limits the stack forming area 102 both in its upper limiting position and in its lower limiting position. The stack forming area 102 is therefore preferably dynamic in its extent. Preferably, the at least one upper stack limiter 116; 117; 118 is arranged to be movable 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 108 and independently of the at least one first side stop 109.

[0053] The vibrating device 101 preferably has a plurality of upper stack limiters 116; 117; 118. In an alternative or additional development, the vibrating device 101 is preferably characterized in that the vibrating device 101 has at least one inner upper stack limiter 116, which delimits the stack forming area 102 upwards in at least one inner region 137. This at least one inner region 137 is spaced from each edge 138 of the stack 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, and even more preferably at least 200 mm in each horizontal direction A; B; S; T. Inner regions 137 can also be present in which no inner upper stack limiter 116 directly delimits the stack forming area 102 upwards.Preferably, the at least one inner upper stack limiter 116 is arranged to be movable with respect to a horizontal direction B, S, T. For example, the at least one inner upper stack limiter 116 is arranged to be movable between at least one parking position and at least one use position, in particular with respect to the transport direction T. Preferably, the at least one inner upper stack limiter 116 can be arranged in different use positions adapted with respect to the at least one horizontal direction B, S, T. This enables adaptation to sheets 103 of different formats. For example, the at least one inner upper stack limiter 116 is designed as a spreading element 116, in particular as a spreading roller 116. In addition to its function as an upper stack limiter 116, this can serve to apply a force from above to the sheet stack 104 at the end of the jogging process and can be moved linearly in the process.This allows any air still contained between the sheets 103 in the sheet stack 104 to be expelled from the sheet stack 104, thereby stabilizing the sheet stack 104. As an alternative to a spreader roller 116, a sliding, non-rolling component can also be used.

[0054] The vibrating device 101 preferably has a plurality of upper stack limiters 116; 117; 118. In an alternative or additional development, the vibrating device 101 is preferably characterized in that the vibrating device 101 has at least one upper stack limiter 117; 118 designed as an edge limiter 117; 118, which delimits the stack forming area 102 upwards in at least one edge region 139. The at least one upper stack limiter 117; 118 designed as an edge limiter 117; 118 delimits the stack forming area 102 upwards in at least one edge region 139, which is spaced from an edge 138 of the stack forming area 102 by at most 50 mm, more preferably at most 20 mm, even more preferably at most 10 mm, and even more preferably at most 5 mm, relative to at least one horizontal direction A; B; S; T. This distance from an edge is to be measured, for example, in a horizontal direction A; B.Edge regions 139 may also be present in which no edge limiter 116 directly limits the stack forming region 102 at the top.

[0055] For example, the upper stack limiters 116; 117; 118 can be at least partially lowered so far that they are arranged only within the lower or second half-space H2. A stack of sheets 104 can then be transported over them unhindered. Alternatively, the upper stack limiters 116; 117; 118 can be removed upwards from a designated transport path of a stack of sheets 104. 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 a side stop 109; 141, and / or at least two lateral edge limiters 117 are arranged, in particular on both sides of the stack forming area 102 relative to the transverse direction A, in particular in the region of at least one or preferably each of the side stops 109; 141.

[0056] This vibrating device 101 is suitable for a preferred method for operating a vibrating device 101. In such a method, a roughly stacked sheet stack 104, for example, is arranged on a stack support device 106. In one embodiment, the stack support device 106 is pivoted about at least one pivot axis, more preferably about two pivot axes. During a vibrating process, the sheet stack 104 is preferably set in motion by means of at least one vibrating drive 122. During the vibrating process, at least one gas or gas mixture, in particular air, is blown between sheets 103 of this sheet stack 104 by means of a stack ventilation device 112. During the vibrating process, at least one gas or gas mixture, in particular air, is preferably additionally blown between a bottommost sheet 103 of this sheet stack 104 and the stack support device 106 by means of the stack ventilation device 112.Preferably, during the shaking process, at least one upper stack limiter 116; 117; 118 is moved alternately up and down, thereby repeatedly exerting a force on at least one uppermost sheet 103 of the sheet stack 104. In an alternative or additional development, the method is preferably characterized in that before or during the shaking process, at least one gas ejection device 113 is transferred from a lowering position to a ventilation position, and that during or after the shaking process, this at least one gas ejection device 113 is transferred from its ventilation position to the lowering position.Preferably, the vibrating device 101 is used for the method, the stack ventilation device 112 of which is designed as a rear blowing device 112 and in which the stack forming region 102 is arranged between at least one gas ejection device 113 and at least one front stop 108 with respect to the first transport direction T.
