Description

The invention relates to a transport vehicle for transport sheet-shaped objects, in particular banknotes between different stations in one for handling the sheet-shaped objects certain device comprising a Frame part with two parallel side walls, a between this extending sheet support and Guide elements for engagement with within the Device arranged guideways are intended to a the frame part arranged frame drive for moving the Transport trolley along the guideways and at least a clamping element attached to the frame part between a Closed position in which it is stretched against the sheet support is adjustable, and an open position in which it is lifted off the support surface.

A trolley of the aforementioned type is for example from EP 0 866 429 A1. To the Outside of the side walls are mounted gears, the from a arranged on the trolley drive motor be driven and engaged with racks are determined, which are along the guideways extend. In this way, the dolly can move automatically along the guideways. Of the Dolly serves for example in an ATM to change a banknote bundle from one vault to another Stations of the ATM to transport. As the Banknotes loaded in the trolley and out of it are not closer in this document explained.

From US-4,624,359 is a similar dolly known, which is not self-propelled, but to Punch tapes hanging over suitable spiked wheels in Guideways are pulled. In this dolly the banknotes are stacked on the Sheet support filed, with the rotational speed the stacking wheel is chosen so that to be deposited banknotes do not rebound from the sheet pad. This solution has the disadvantage that banknotes only with a low Sheet storage frequency can be stored.

The invention is based on the object, a Specify a trolley of the type mentioned, the be loaded reliably with high Blattablagefrequenz can.

This object is achieved in that the Dolly brake finger has a bounce-free Allow for leaflet placement at high reel rate.

With the trolley according to the invention, it is possible a Sheet bundles, especially banknote bundles, reliable and quickly put down on a sheet pad.

Such a trolley for transport sheet-shaped Items are preferably in cash dispensers used.

The trolley comprises a frame part with two mutually parallel side walls, one between this extending sheet support and at least one Clamping element, which on the frame part between a Closed position in which it is stretched against the sheet support is adjustable, and an open position in which it is lifted off the support surface. The clamping element is formed in the form of a flap which is around a pivoting on the side walls perpendicular to the axis Frame part is stored and safely prevents the transported leaves during the movement of the Transport trolley through the device with other equipment parts in Come in contact.

The flap is on one in the side walls of the Frame part mounted shaft arranged with at least a lever is rotatably connected to the Interaction with at least one device-side Stellelement is formed. In this way, the Flap in the respective stations conveniently opened or getting closed. To the adjustment mechanism for the To simplify flap it is expedient if the shaft opposite the frame part in one of the opening movement of the Flap corresponding position is biased. So that can adapt the flap to different bundle strengths, it is expediently on the shaft for a limited Angle is pivotable and opposite the shaft in one of its Opening movement biased opposite direction. The car drive has in a known manner at least a drivable by a drive motor, on the frame part mounted gear that is engageable with a along the Guideways provided rack is determined. Preferably, the drive motor of the carriage drive and the belt motor co-axially with each other and with their axes perpendicular to the side walls between these on the Frame part arranged.

The banknotes taken from banknote cassettes become individually inserted in the trolley, with the flap is in its open position. Introducing the single leaves is usually done with a considerable speed. To prevent the Leaves bounce back are on the frame part between this and the flap brake finger arranged around an axis parallel to the flap axis swiveling and away from the sheet pad towards a bias the swing path limiting stop are biased such that the brake fingers with the flap open a middle position between this and the sheet support taking. This facilitates the formation of an orderly Sheet bundle in the dolly. Usually occurs the filing of the individual sheets in the trolley by means of a stacking wheel. Appropriately, therefore, in the Flap directed perpendicular to the flap pivot axis adapted to receive the fingers of a stacking wheel, wherein the brake fingers each lie opposite the slots, so that the fingers of the stacking wheel through the slots in the Submerge the trolley and place the leaves one by one against the Can lay brake fingers.

The illustrated in Figure 1 generally with 10th designated trolley is used to transport Banknotes inside a banknote machine. He includes one generally with 12 designated frame part with two mutually parallel side walls 14, between which a support plate 16 for the transported Banknotes stretches. On the frame part 12 is a generally designated 18 flap to a perpendicular to the side walls 14 directed axis 20 pivotally stored, which serves, in its closed position while lying on the platen 16 notes the movement of the trolley 10 through the ATM hold. Further, referring to Figures 2 and 3, the frame part 12 and the flap 18th initially explained in more detail.

The section intended for holding banknotes Frame part 12 is from the support plate 16, the Side walls 14 and one perpendicular to these Partition wall 22 limited. On the outside of the side walls 14 are first guide elements in the form of one each Roller 24 and a slider 26 arranged on a perpendicular to the side walls 14 extending shaft 28 are rotatably mounted. Only the role 24 and the slider 26 closer to the viewer To recognize side wall 14. Same elements are located but also on the outside of the viewer further lying side wall 14. In the on the intermediate wall 22nd protruding portions 30 of the side walls 14 is a to the shaft 28 parallel shaft 32 mounted on the ends each second roller-shaped guide elements 34 rotatable are stored, although only the viewer is close Guide element 34 can be seen. The guide elements 24, 26 and 34 are intended for engagement in guideways, which are arranged within the banknote machine and between which the dolly from a station to move to another.

Between the sections 30 of the side walls 14 are also two electric motors 36 and 38 arranged so that their Drive axes co-axial and perpendicular to the side walls 14 are directed. The two electric motors 36 and 38 are connected via a coupling piece 40 and each via a gear housing 42, 44 at the respective Sidewall portion 30 attached. The closer to the viewer located electric motor 36 is the drive motor of the Car drive. He drives over an unrepresented Transmission two with the shaft 32 rotatably connected pinion 46, which is outside the side wall portions 30th directly axially adjacent to the second guide elements 34 are arranged and of which in Figure 2 only one recognize. These pinions 46 engage in along the Guides running racks, so the To move trolley 10 along the guideways.

The second electric motor 38 forms the drive motor for a sheet conveying device which serves To feed banknotes into the trolley or out to spend this. This sheet conveying device comprises the frame part 12 first endless belt 48, which is parallel to the side walls 14 are arranged between them and on the one hand via a rotatable on the shaft 32 mounted hollow shaft 50 and on the other hand, a near the free edge of the support plate 16 in this freely rotatable mounted deflection roller 52 are guided. The belt motor 38 does not drive over a contained in the transmission housing 44 illustrated drive pinion, an intermediate gear 54, on the one hand with its adjacent hollow shaft 50th rotatably connected gear 56 drives and on the other hand with a gear 58 is engaged, the rotation with an intermediate shaft 60 parallel to the shafts 28 and 32 connected is. Near the viewer Side wall portion 30 is on the intermediate shaft 60 a another gear 62 attached, which has a in the Gearbox 42 stored freely rotatable Intermediate gear 64 a not visible in Figure 2 Gear drives in unison with the viewer near hollow shaft 50 is connected so as to the viewer to drive close endless belts 48. The belt motor 38 is reversible in its direction of rotation so that the endless belts 48 in both directions of rotation, i. in both by the Double arrow A directions are drivable.

Between the visible in Figure 2 inner Trumen of Endlosriemens 48 and below the support plate 16th extending outer Trumen of the respective endless belt 48th is a support roller 66 mounted by a not illustrated spring perpendicular to the plane of the support plate 16th is biased inwards.

In Figures 1 and 2 can be seen also flat elongated Brake finger 68, of which the two middle by a Crosspiece 70 are interconnected and the the Pass through the intermediate wall 22 and with their inner ends are pivotally mounted on the intermediate shaft 60. The Brake fingers 68 are not by in the figure 2 recognizable, running below the platen 16 Tension springs biased so that they in the direction of the arrows 72nd in Figure 2, i. counterclockwise around the Intermediate shaft 60 in a shown in the figure 1 are biased raised position.

The flap 18 shown in FIG. 3 comprises a shaft 74, which in the assembled state of the trolley 10th Bearing holes 76 interspersed in the Side wall sections 30 are formed. On the shaft 74 a flap plate 78 is mounted, which through each other parallel slots 80 in a plurality of finger-shaped Sections 82 is divided. In the area of the two outer finger 82 is rotatably with the shaft 74 respectively Bracket 84 is connected to which a to the shaft 74 co-axial first torsion spring 86 is supported with its one end, while the other end on the finger 82 attacks and the Finger 82 and thus the entire flap plate 78 against a rotation stop, not shown on the shaft 74th stressed. This allows the flap plate 78 relative to the Ironing 84 and thus to the shaft 74 against the bias the torsion spring 86 are deflected. Another to Shaft 74 co-axial torsion spring 88 engages with her one End of the respective finger 82 and is with her other end to rest against a stop of the frame part 12 determined to the flap 18 in the in the figure 1 to bias shown open position.

At the ends of the shaft 74 are perpendicular to this directed lever 90 attached, with the help of the Flap 18 is pivoted into its closed position and in this can be held. For this purpose, the Lever 90 near their free ends to each other facing inner surfaces each have a latching nose 92, the each at one on the side wall portion 30th formed locking surface 94 is supported when the flap 18 in 1 in a clockwise direction against the support plate 16 out is pivoted and thereby the lever 90 in the direction of the arrow B are raised in Figure 1. The levers 90 consist of a degree of elasticity Plastic material and snap into your own Locking position on. To open the flap 18 the levers 90 by device-fixed cam from each other pushed away, whereby the locking lugs 92 of the locking surfaces 94 are lifted so that the flap 18 under the effect the torsion springs 88 in the illustrated in Figure 1 Opening position is raised.

The two outer fingers 82 of the flap plate 78th adjacent fingers 82 serve as guide elements for two Another endless belt 96, on the one hand in each case via a on the shaft 74 mounted roller 98 and on the other hand one near the free end of the respective finger 82 free rotatably mounted pulley 100 run. The rollers 98 are each rotatably connected to a gear 102, the in the frame part 12 each one with the intermediate shaft 60th rotatably connected gear 104 is assigned, so that the Gears 102 and 104 mounted on the frame part 12th Flap 18 engage each other and the Endless belt 96 in synchronism with the endless belts 48 can be driven. The axial position of the endless belts 96 is chosen so that each of the endless belt 96 a Belt pair with one of the belt 48 forms. Between the Roller 98 and the guide roller 100 is one each Support roller 106 freely rotatably mounted, which by a not shown spring against the visible in the figure 3 inner strand of the endless belt 96 is stretched and this Thus, with the flap 18 closed against a between the Strap 48 and 96 lying banknote bundle presses.

In the open position of the illustrated in the figure 1 Dolly can have individual banknotes in the Dolly be inserted. To do this, the fingers grab known per se stacking wheels through the slots 80th between the fingers 82 of the flap 18 and put the Bank notes individually on the brake fingers 68, the axial lie opposite the slots 80. Will the dolly 10 then by actuation of the drive motor 36 from this Loading position moves are via corresponding cam tracks on the device, the lever 90 is pivoted to the flap 18 to close, with the between the brake fingers 68 and the flap plate 78 lying notes of the itself closing flap 80 pressed against the platen 16 become. A different bundle strength can thereby the possible angular play of the flap plate 78 relative to the brackets 84 and thus compensated for the shaft 74 become. In the closed state can now Banknotes bundle from the trolley 10 to another Processing station, such as an output station be driven. At this station becomes the banknote bundle by turning on the belt motor 38 from the belt pairs 48, 96 without opening the flap 18 from the trolley 10th transported out. For example, if the customer removes it Banknotes bundle not, it is by switching the Belt motor 38 fed back into the trolley and For example, this can become a reject tray be transported, in which the withdrawn banknotes are stored, the belts 48, 96 again in the sense be driven a banknote issue.
