The object of the invention is to provide a vibrating device and a method for operating a vibrating device.

The object is achieved according to the invention by the features of claim 1 and the features of claim 2 and the features of claim 17.

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 stack of sheets that is smoothly stacked. The jogging device has at least one pivotally arranged stack support device, which defines a support plane whose position is stationary 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 which a stack forming area is and/or can be limited in a first transport direction. The jogging device has at least one first side stop, by means of which the stack forming area is and/or can be limited in a transverse direction orthogonal in particular to the transport direction. The support plane preferably forms a lower boundary of the stack mold area. The jogging 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. In a preferred development, the at least one gas ejection device is arranged such that it can be transferred between at least one respective lowered position and at least one respective ventilation position, in particular transferrable in the vertical direction. The at least one gas ejection device is preferably arranged at least partially in the first half-space in its respective at least one ventilation layer. In its respective at least one lowered position, the at least one gas ejection device is preferably arranged completely in the second half-space, ie in particular not arranged in the first half-space.

This offers the advantage that all the sheets in a stack of sheets can be influenced by means of the blowing device and yet the blowing device cannot collide with the stack support device. This is preferably also possible when sheets are shorter in their dimensions than a maximum format, in particular when corresponding receiving openings are provided. Nevertheless, maximum mobility of the sheets during their transport is guaranteed.

In an alternative or additional refinement, the vibrating device is preferably characterized in that the at least one gas ejection device each has an ejection opening or gas ejection opening or a plurality of ejection openings gas 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, more preferably at least 35 mm, and even more preferably at least 50 mm in the vertical direction. As a result, a particularly large part of the stack of sheets can be loosened up at the same time. A maximum height of a stationary sheet stack is preferably at most 55 mm, more preferably at most 30 mm.

In an alternative or additional refinement, the jogging device is preferably characterized in that the jogging device has at least one upper stack limiter which is and/or can be arranged at least temporarily above the stack forming area and upwardly limits the stack forming area. Then particularly large volumes of gas can be blown into the sheet stack without destroying it. This loosens up the stack of sheets to a particular degree and allows the stack of sheets to be smoothed out particularly efficiently. In an alternative or additional refinement, the jogging device is preferably characterized in that the at least one upper stack limiter can be moved between at least one upper limit position and at least one lower limit position. In particular, the at least one upper stack limiter is arranged further up in its at least one upper limit position in relation to the vertical direction than in the at least one lower limit position.

In an alternative or additional refinement, the jogging device is preferably characterized in that the jogging device has at least one inner upper stack limiter, which upwardly limits the stack forming area in at least one inner area that is at least 10 mm, preferably at least 20 mm, in relation to each horizontal direction , 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 mold area. Then a central area can be bounded upwards independently of border areas, which allows an optimized operation of the upper stack limiters. In an alternative or additional refinement, the jogging device is preferably characterized in that the jogging device has at least one upper stack limiter designed as an edge limiter, which limits the stack shape area upwards in at least one edge area, which, in relation to at least one horizontal direction, is at most 50 mm, preferably at most 20 mm, more preferably at most 10 mm, and even more preferably at most 5 mm from an edge of the stack molding area.

In an alternative or additional refinement, the jogging device is preferably characterized in that, in relation to the first transport direction, the stacking area 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 defined 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. Then, regardless of a width of the sheets, the gas ejector can always be used. It is also advantageous to blow gas or air into the stack of sheets from behind, because one of two opposite side stops can then be used as desired.

In an alternative or additional refinement, 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, which are arranged one above the other with respect to the vertical direction. Different areas of the stack of sheets can then be subjected to different, in particular adapted, pressures or volume flows in relation to the vertical direction. In an alternative or additional refinement, the vibrating device is preferably characterized in that a narrowest point of a lowermost gas supply line, which leads to a lowermost one of the several ejection openings of a respective gas ejector device, has a larger cross-sectional area through which flow can take place than a narrowest point of an uppermost gas supply line, which leads to an uppermost one of the plurality of ejection openings of this respective gas ejection means.

In an alternative or additional refinement, 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 that the stack support device is arranged pivotably independently of the at least one gas ejection device. As a result, the vibrating device is particularly robust with regard 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 refinement, the jogging 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 that the at least one gas ejection device is arranged such that it can be moved at least partially through a respective receiving opening in order to switch between the at least one respective lowered position and to be transferred to the at least one respective ventilation layer. This enables an optimized, for example format-adapted, arrangement and alignment of the at least one gas ejection device with a simultaneously optimized shaking movement. In an alternative or additional refinement, the vibrating device is preferably characterized in that the at least one receiving opening extends in a displacement direction, which is preferably oriented parallel to the ejection direction and/or the first transport direction, and that the at least one gas ejection device can be moved in the displacement direction while it protrudes through the respective receiving opening into the upper half-space and/or is arranged transferable at different longitudinal positions between at least one respective lowered position and at least one respective ventilation position in relation to the direction of displacement. 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.

In an alternative or additional development, the vibrating device stands out preferably characterized in that the at least one receiving opening has a respective gas guiding surface at its end opposite the respective ejection opening in the displacement direction and/or the ejection direction and/or the first transport direction, the upper end of which is arranged further away from the respective ejection opening than its lower end Diploma. This causes gas to be transported under a lowermost arch and improves its mobility. In an alternative or additional refinement, the jogging 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 conduction area and that the at least one support area and the support plane touch one another tangentially and that the at least one gas conduction area extends from the support plane is arranged in the second half-space at a distance in relation to the vertical direction, in particular lower or in relation to a surface normal away from the support plane. For example, this is realized by arranging at least one checker plate.

In an alternative or additional refinement, 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 in the 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 is more preferably arranged after the at least one ejection opening of the respective gas ejection device, viewed in the ejection direction. This improves gas flow by redirecting a portion and then transporting it with a component in the vertical direction.

In an alternative or additional refinement, the jogging device is preferably characterized in that the stack aeration 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 at a distance from one another in the transverse direction. These gas ejection devices preferably each have one ejection opening or a plurality of ejection openings. More preferably, these are also designed such that they 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. 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. As a result, the gas flow is introduced into the stack of sheets in an optimized manner in the transverse direction and, for example, it can be adapted to sheets of different widths by means of targeted activation or partial switching off.

A method for operating a jogging device is preferred, in which an in particular roughly stacked stack of sheets is arranged on a stack support device and in which the stack support device is preferably pivoted about at least one pivot axis, more preferably two pivot axes, and in which the stack of sheets is set in motion in a jogging process by means of at least one jogging drive and wherein during the jogging 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 jogging process at least one upper stack limiter is moved up and down alternately and a force is thereby repeatedly exerted on at least one uppermost sheet of the Sheet stack is exercised. This limits the height of the stack of sheets and allows a particularly large amount of air to be introduced into the stack of sheets, as a result of which the sheets can be mobilized in a special way and then aligned. In an alternative or additional development, the method is preferably characterized in that at least one gas or gas mixture, in particular air, is additionally blown in between a bottom sheet 103 of this sheet stack 104 and the stack support device 106 during the jogging process by means of the stack ventilation device 112. In an alternative or additional development, the method is preferably characterized in that before the shaking process or during the shaking process, at least one gas ejection device is transferred from a lowered position to a ventilation position, and that during the shaking process or after the shaking process, this at least one gas ejection device is moved from its ventilation position to the reduction is transferred. This facilitates the handling of the stack of sheets outside of the jogging process and the device can nevertheless be designed and operated in a space-saving manner.

A jogging device 101 is preferably embodied 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 pivotally arranged stack support device 106 on. For example, this stack support device 106 can be pivoted about at least two pivot axes, which are preferably oriented orthogonally to one another. A first pivot axis of this type extends, for example, in a first horizontal direction T, which is also referred to in particular as the first transport direction T. A second pivot axis of this type extends, for example, in a second horizontal direction A, which is also referred to as the transverse direction. A respective pivoting angle is preferably adjustable and is, for example, between 1° and 30°, preferably between 5° and 20°.

A support plane 111 is defined by the stack support device 106 . A support plane 111 is to be understood in particular as a plane 111 that defines a lower end of an ideally cuboid stack of sheets 104 that is located on the stack support device 106 . The position of the support plane 111 relative to the stack support device 106 is stationary. This means that when the stack support device 106 pivots, the support plane 111 is also given accordingly. The stack support device 106 has, for example, essentially a stack support surface 107, which does not have to be flat, but rather has means, for example, 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 elevations.

The support plane 111 separates an upper half-space H1 from a lower half-space H2. Under a respective half-space H1; H2 is a half-space H1; To understand H2 in the mathematical sense. Regardless of a pivoted 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 that is oriented upwards in the vertical direction V. Starting from the support plane 111, this normal vector points into the upper half-space H1.

The jogging device 101 has at least one first front stop 108, by which a stack forming area 102 is and/or can be limited in the first transport direction T. The stack forming area 102 is preferably that of Raumbe Rich 102, which is intended to be filled at least temporarily by the sheets 103 of a sheet stack 104 from the beginning of a jogging process to the end of this jogging process. The stack forming area 102 is therefore that spatial area 102 which the sheets may occupy at least temporarily during the jogging process, regardless of their desired position at the end of the jogging process. In this jogging process, the stack of sheets 104 is preferably transferred from a roughly stacked stack of sheets 104 to a stack of sheets 104 that is evenly stacked. In particular, this means that the sheet stack 104 is in a roughly stacked state at the start of the jogging process and is in a smoothly stacked state at the end of the jogging process. The stack mold area 102 is preferably formed at least in part by components 106; 108; 109; 116; 117; 118; 141 of the vibrating device 101 is limited. In particular, these components 106; 108; 109; 116; 117; 118; 141 of the jogging device 101, it is preferred that the sheets 103 of the sheet stack 104 remain in the stack forming area 102 from the beginning of the jogging process to 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 depend, for example, on the format of the sheets 103, for example if two side stops 109; 141 are used or upper stack limiters 116; 117; 118 depending on the format. The stack molding area 106 is preferably arranged in the first half space H1. Because the stack support device 106 can pivot, the respective stack of sheets 104 can be pushed against the at least one front stop 107 and/or the at least one side stop 109; 141 to be leaned. Then the stack shape range is also limited due to gravity in the respective opposite direction and its corresponding limit is determined, for example, by the shape of the respective roughly stacked sheet stack 104.

The at least one front stop 108 is preferably arranged such that it can move 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 such that it can be changed between a transfer position and a retention position. When front stop 108 is arranged in the retention position, it preferably projects further into the first half-space H1 than when front stop 108 is arranged in the transfer position. More preferably, the at least one front stop 108 is located completely outside of the first half-space H1 when it is arranged in its transfer position. Then, for example, a stack of sheets 104 that has been stacked evenly can be transported away beyond the at least one front stop arranged in its transfer position.

The jogging device 101 has at least one first side stop 109 . The stacking forming area 102 is 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 transport direction T. The jogging device 101 preferably has at least one second side stop 141. The stacking form region 102 is and/or can be limited by the at least one second side stop 141 in or counter to the transverse direction A. In relation to the transverse direction A, the stacking forming area 102 is preferably arranged between the at least one first side stop 109 and the at least one second side stop 141. The at least one side stop 109; 141 is preferably arranged such that it can move 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 such that it can be changed between a stop position and a passing position. With the side stop 109; 141, this preferably protrudes further into the first half-space H1 than when the side stop 109 is arranged in the passing position; 141. The respective lateral stop 109; 141 completely outside the first half space H1 when placed in its pass position. Then, for example, a roughly stacked stack of sheets 104 can be moved past the at least one side stop arranged in its passing position and into the stack forming area. The at least one side stop 109; 141 is preferably pivotably arranged, in particular about an axis which is oriented parallel to the vertical direction V and/or parallel to the normal vector of the support plane 111. As a result, an adaptation to trapezoidal arches 103 can take place, for example in the case of relatively long side stops.

The vibrating device 111 preferably has at least one vibrating drive 122. This vibrating drive 122 has, for example, a stationary part that is designed as a stator, for example, or has a stator. This vibrating drive 122 has, for example, a movable part which is designed as a rotor, for example, 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 connected to the movable part of vibrating drive 122.

The stack aeration 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. In relation to the first transport direction T, the stack forming area 102 is preferably arranged between the at least one gas ejection device 113 and the at least one front stop 108.

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 such that it can be transferred between at least one respective lowered position and at least one respective ventilation position, in particular in the vertical direction V. The at least one gas ejection device 113 is preferably in their respective at least one ventilation position is at least partially arranged in the first half-space H1 and the at least one gas ejection device 113 is arranged completely in the second half-space H2 in its respective at least one lowered position.

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 an ejection opening 114 or a plurality of ejection openings 114. This at least one ejection opening 114 is designed in particular as a gas ejection opening 114 and is connected to a compressed air source, for example. These one or more ejection openings 114 extend or extend 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 50mm The respective at least one ejection opening 114 in the respective ventilation layer preferably extends over at least 15 mm into the 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 more preferably over at least 50 mm.

For example, the respective ejection openings are at least 0.5 mm wide in relation to the transverse direction A, more preferably at least 1 mm. For example, the width of the respective ejection openings in relation to the transverse direction A is at most 10 mm, more preferably at most 5 mm and even more preferably at most 2 mm.

In an alternative or additional development, 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 that is oriented parallel to the first transport direction T, and more preferably that this ejection direction is parallel to the first Transport direction T is oriented.

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 two or at least three ejection openings 114, which 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, which 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 the gas ejection devices 113 each have at least two or at least three ejection openings 114, which are arranged one above the other with respect to the vertical direction V.

All ejection openings 114 of a respective gas ejection device 113 and more preferably all ejection openings 114 of all gas ejection devices 113 are preferably arranged in a manner connected to a common gas supply line 142 . In an alternative or additional development, 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 ejection openings 114 of a respective gas ejection device 113, has a larger cross-sectional area through which flow can take place than a narrowest point of an uppermost one Gas supply pipe 121 leading to an uppermost one of the plurality of ejection openings 114 of this respective gas ejection device 113. Despite the connection to the common gas supply line 142, this ensures that gas or gas mixture is ejected from the bottom ejection opening 114 at a higher pressure than from the top ejection opening 114. The amount of gas introduced into the stack of sheets 104 can thus be influenced depending on the altitude . For example, the corresponding cross-sectional areas can be adjusted, in particular by using a corresponding one Component with a correspondingly large opening, in particular a respective panel.

In an alternative or additional development, 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 such that it can pivot independently of the at least one gas ejection device 113.

The stack support device 106 preferably has at least one receiving opening 123, more preferably several 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 such that it can be moved at least partially through a respective receiving opening 123, in particular in order to be transferred between the at least one respective lowered 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.

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

In an alternative or additional development, the vibrating device 101 is preferably characterized in that the at least one receiving opening 123 has a respective gas guiding surface 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 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-guiding surface 124 is a flat, obliquely oriented surface. This allows gas moving parallel to the support plane 111 to be diverted upwards to lift a bottom sheet 103 of a corresponding stack of sheets 104 .

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

In an alternative or additional development, 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 is independent of the position of the respective at least one gas ejection device 113 is always arranged in the second half-space H2 and the upper end 134 of which, at least in relation to the ejection direction B, 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. In particular, this is at least one deflection surface 133, viewed in the ejection direction B, is arranged after the at least one ejection opening 114 of the respective gas ejection device 113. Such a deflection surface 133 makes it possible to generate an upward gas flow in the area of the beginning of a stack of sheets 104, which advantageously directs the gas into spaces between individual sheets 103 and/or between a bottom sheet 103 of this stack of sheets 104 and the stack support device 106.

In an alternative or additional development, the jogging device 101 is preferably characterized in that the stack aeration 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 located in the transverse direction A are spaced apart.

In an alternative or additional development, the vibrating device 101 preferably has at least one upper stack limiter 116; 117; 118 on. The at least one upper stack limiter 116; 117; 118 is preferably at least temporarily arranged and/or can be arranged above the stack forming area 102. In an alternative or additional development, the at least one jogging device 101 is preferably characterized in that the at least one upper stack limiter 116; 117; 118 limits the stack mold 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 stack of sheets 104 can be produced and that sheets 103 do not drift off too far, even if the stack of sheets 104 is greatly loosened up by air being blown in.

Preferably, the at least one upper stack limiter is 116; 117; 118 can be moved between at least one upper limit position and at least one lower limit position. This allows the stack of sheets 104 to be processed dynamically. The at least one movable upper stack limiter 116; 117; 118 movements are introduced, in particular in addition to the shaking movements that the at least one shaking drive 122 generates. On the one hand, this expels the gas or gas mixture, in particular the air, from the stack of sheets 104 and, on the other hand, increases the mobility of the sheets 103, so that they are pressed against the at least one front stop 108 and the at least one side stop 109; 141 can slide and thus a smoothly stacked stack of sheets 104 can be produced.

The at least one upper stack limiter 116; 117; 118 preferably delimits the stack mold area 102 both in its upper limit position and in its lower limit position. The stack mold area 102 is therefore preferably dynamic in its extent. Preferably, the at least one upper stack limiter is 116; 117; 118, independently of the at least one first front stop 108 and independently of the at least one first side stop 109, so as to be movable between the respective at least one upper limit position and the respective at least one lower limit position.

The jogging device 101 preferably has a plurality of upper stack limiters 116; 117; 118 on. In an alternative or additional development, the jogging device 101 is preferably characterized in that the jogging device 101 has at least one inner upper stack limiter 116, which upwardly delimits the stack forming area 102 in at least one inner area 137. This at least one inner area 137 is limited to each horizontal direction A; B; S; T is spaced at least 10mm, more preferably at least 20mm, even more preferably at least 50mm, even more preferably at least 100mm, and even more preferably at least 200mm from each edge 138 of the stack mold area 102. In this case, inner regions 137 can also be present in which no inner upper stack limiter 116 delimits the stack mold region 102 directly at the top. The at least one inner upper stack limiter 116 is preferably arranged such that it can move with respect to a horizontal direction B, S, T. For example, the at least one inner upper stack limiter 116 is arranged so that it can move between at least one parked position and at least one use position, in particular with respect to the transport direction T. The at least one inner upper stack limiter 116 is preferably related in different directions to the at least one horizontal direction B, S, T adapted application positions can be arranged. This enables adaptation to sheets 103 of different formats. For example, the at least one inner upper pile limiter 116 is embodied as a leveling element 116, in particular as a leveling roller 116. In addition to its function as an upper pile limiter 116, this can also be used to apply a force from above onto the sheet pile 104 at the end of the jogging process and be moved linearly in the process. As a result, air still contained in the stack of sheets 104 between the sheets 103 can be expelled from the stack of sheets 104 and the stack of sheets 104 can thereby be stabilized. As an alternative to a wiper roller 116, a sliding, non-rolling component can also be used.

The jogging device 101 preferably has a plurality of upper stack limiters 116; 117; 118 on. In an alternative or additional development, the vibrating device 101 is preferably distinguished characterized in that the vibrating device 101 has at least one edge limiter 117; 118 formed top stack limiter 117; 118 which delimits the stack forming area 102 in at least one edge area 139 at the top. The at least one edge limiter 117; 118 formed upper stack limiters 117; 118 delimits the stack forming area 102 in at least one edge area 139 at the top, which points to at least one horizontal direction A; B; S; T related is spaced 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 from an edge 138 of the stack mold area 102 . This distance from an edge is, for example, in a horizontal direction A; to measure B. Edge areas 139 can also be present in which no edge limiter 116 directly delimits the stacking form area 102 upwards.

For example, the top stack limiters 116; 117; 118 at least partially lower so that they are only arranged within the second half-space H2. A stack of sheets 104 can then be transported over it unhindered. Alternatively, the top stack limiters 116; 117; 118 can be removed upwards from an intended transport path of a stack of sheets 104. For example, at least one front edge limiter 118 is arranged, in particular in the area of the front stop 108, and/or at least one lateral edge limiter 117 is arranged, in particular in the area 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 in relation to the transverse direction A, in particular in the area of at least one or preferably one side stop 109; 141

This jogging device 101 is suitable for a preferred method for operating a jogging 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. In a jogging process, the stack of sheets 104 is preferably set in motion by means of at least one jogging drive 122.

During the jogging process, at least one gas or gas mixture, in particular air, is preferably additionally blown in between a bottom sheet 103 of this sheet stack 104 and the stack support device 106 by means of the stack ventilation device 112. At least one upper stack limiter 116; 117; 118 is alternately moved up and down and a force is thereby repeatedly exerted 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 the shaking process or during the shaking process, at least one gas ejection device 113 is transferred from a lowered position to a ventilation position, and that during the shaking process or after the shaking process, this at least one gas ejection device 113 is moved out of its position Ventilation layer is transferred to the lowering layer.
