Description

Feeding loose leaf groove

The invention relates to a method and a device for feeding loose sheet material to a Blattgutvereinzler and a Entbanderolierungsvor- direction thereof. The invention further relates to a banknote processing plant with a sheet material singler and such a feeding device.

Each banknote sorting machine is usually preceded by one or more Blattgutvereinzler. In an input tray of the Blattgutvereinzler piles of loose bills are inserted, and the banknotes are deducted from this stack individually, checked in the sorter according to certain criteria and re-sorted accordingly.

EP 0 764 131 B1 proposes various measures for increasing the throughput rate of the singler in order to be able to carry out the singling process without interruption. In an embodiment described as being preferred, the input compartments are designed to be transportable and can be filled with sheet material at a loading position and transported to one or more singlers. For transporting the input compartments, a corresponding transport system is provided, which may comprise one or more transport routes, which may also be interconnected. In the transport route, several of the transportable input compartments can be arranged one behind the other. The transport route thus has memory function. In particular, the input tray consist of two parts, wherein the upper part is arranged stationary in the singling and only the lower part is designed to be transportable to be transported by means of the transport system from the loading position for filling the input tray to the singler or singlers.

In many printing houses banknotes in a cutting system in which they are cut from appropriate sheets in the prescribed format, combined by means of banderoles to banknote stacks of 100 banknotes, so-called banknotes. This facilitates the manual Banknotes and makes the transport of banknotes safer compared to loose transported banknotes. Only before inserting the banknote stack or banknote packets in the transportable input tray the bands are removed manually again. This is disadvantageous because of the associated personnel expenses.

The object of the present invention is therefore to automate the process of debranching, in particular within the overall system described in EP 0 764 131 Bl, in a favorable, if appropriate also optimal manner.

This object is achieved by a method and a device as well as by a bank note processing system having the features of the independent claims. In dependent claims advantageous embodiments and developments of the invention are given.

According to the invention the Entbanderolieren not done before placing the sheet stack or banknotes in the transportable input tray, but later during the transport of the subject or during a transport break. D. h., The sheet stacks are stored in banderoliertem state in the transportable compartment and automatically removed during transport for Vereinzier or during a transport break from the transportable compartment and freed from the banderoles to obtain in this way a loose sheet stack, the then is transported to the Blattgutvereinzler. As a transport break in the context of the present invention, a period to be understood, which is after filling a tray with stacks of sheets and before the actual start of transport.

In particular, the invention offers the following two advantages. On the one hand, the reliable and secure handling of the sheet stack or banknote packets is ensured until they are stored in the transportable compartment. The There is a risk that the stack of bills will be messed up after removing the banderoles and before they are placed in the transportable compartment, as has been the case with manual removal of the banderols. On the other hand, the Entbanderolierstation claimed no additional space in the loading position, but can instead be integrated to save space in the transport section for the movable compartments in the system.

Depending on in which region of the transport path Entbanderolieren takes place, the entbanderolierten banknote stacks can be supplied to the Blattgutver- zler either directly or initially transported back to the subject and fed to the Blattgutvereinzier immediately after further transport directly from the tray out. The transportable compartment preferably forms part of the input compartment of the sheet material divider, as described in EP 0 764 121 B1. In this case, the sheet stacks are preferably transported back into the transportable compartment by means of the same transport device with which they were previously removed from the transportable compartment for removing the bands. This variant is preferred, in particular, because the stripper removal station can then be integrated into existing systems, in particular those as described in EP 0 764 121 B1, without requiring special adjustments of the existing systems.

In the event that the Entbanderolieren takes place during transport, so when moving compartment, it is advantageous to perform the Entbanderolierstation so that it is synchronously mitbewegbar along with the transportable compartment along the transport path.

Alternatively, it is also possible to design the transport device in such a way that it at least for the duration of the removal, preferably also the return gens, the or the sheet stack in synchronism with the transportable tray along the transport path mitzubewegen.

The transport device for removing (and returning) the sheet material stack from the transportable compartments preferably comprises two gripping elements in order to receive the sheet material stacks between the gripping elements and to transport them in a clamping manner. In this way, the sheet stack can be lifted out of the subjects upwards as well as pivoted after lifting in a hanging position to be discontinued from this hanging position in the actual Entbanderolierer.

If an investment wall of the subjects has slots, as z. As is the case with the transportable compartments known from EP 0 764 131 B1, it is advantageous to embody the two gripping elements in a comb-like manner so that they can be passed through the slots of the compartments in order to grasp the stack of sheets to be taken from the compartments.

The transportable compartments and, accordingly, also the unloading station can hold a plurality of strapped sheet stacks and are preferably suitable for holding at least five banknote packs per 100 banknotes. In the stripper, the bands of these sheet stacks can be removed either one at a time or in groups one at a time or all at the same time. These serve one or more cutting edges for cutting the bands. These cutters preferably engage the banderoles from one side of the sheetstock, while the severed banderoles are removed from another side of the sheet stock stacks, preferably from a side opposite the cut edges. In this case, the severing of the bands advantageously takes place along the longitudinal edges of the sheet material, so that the cutting edges can dive during the separation process between adjacent sheets of the sheet material stacks and do not damage the sheets. The cutting edge or Cutting can be so displaced that the bands of adjacent Blattgutstapel are successively severable.

When using only one cutting edge, but in particular also when using a plurality of cutting edges which sever or cut through the banderole along the longitudinal edges of the sheet material stack, at least two of the sheets of the sheet material can be forced apart immediately before the step of severing and / or in the step of severing and the cutting takes place in the area of the two leaves. This procedure offers the advantage that damage to the sheet material at the longitudinal edges by the cutting edge or one of the cutting edges can be at least largely avoided.

For this purpose, the Entbanderolierer at least one separating element, in particular a blade, which is arranged in the direction of taking place for separating the band relative movement of Blattgutstapel and cutting edge in front of the cutting edge, so that it moves between two sheets of sheet stack and separates them from each other and the cutting edge partially moved between the leaves. For this purpose, the separating element can have a leading edge to be tapered in the direction of the sheet material stack, which, although substantially tapered, is not sharp.

The cutting edges can in principle be designed as desired. In particular, the cutting edge may comprise a rotating blade about an axis oriented orthogonal to a relative movement between the cutting edge and the sheet material stack, which is set in rotation at least during the separation of the banderole by a drive of the stripper. This embodiment allows a particularly good separation of the band irrespective of the speed of a linear relative movement of the cutting edge and sheet material stack. When using several cutting edges, the cutting edges can in particular be provided by knives rotating about a common axis. This allows a particularly simple construction of the device.

In order to enable a good separation of the band without damaging the sheet material, the banded sheet material stack is preferably aligned for cutting.

According to a first alternative, in the device for this purpose, in a preferred embodiment, the stripper may comprise at least one tray, preferably inclined with respect to the horizontal, on which the at least one stack of sheets for separating the band can be placed. The alignment can be done by gravity in an advantageous manner. In particular, at least one corresponding stop can be arranged for this purpose in the lower region of the tray, against which the sheet material stack is forced onto the tray by gravity.

Further, the Entbanderolierer having a receptacle for receiving entbanderolierenden sheet material stacks for separating the bands, which preferably has one or the inclined on a horizontal tray. Furthermore, the receptacle may have lateral guiding or alignment elements.

In particular, the receptacle can be designed so that the cutting edge and the at least one stack of sheet stacks can be held in alignment relative to one another and in an aligned position during cutting by means of the receptacle. In this way, a particularly precise separation can take place.

Further, it is preferred that the receptacle has at least one movable between a receiving position and a holding position element, wherein in the receiving position of the at least one banded sheet stack in the Recording is insertable and is stable by movement of the element from the receiving position to the holding position of the sheet stack in a predetermined position. This embodiment makes it possible in an advantageous manner to align strip sheets to be unbonded, which have blades bent apart at the ends, in a manner that is secure for strip removal.

In principle, it is sufficient to provide only one movable element by means of which the banknote stack can be held against a corresponding stop. However, it is possible that the receptacle comprises at least one further between a receiving position and a holding position movable element whose movement is coupled to that of the other element so that the sheet stack is clamped in movement from the receiving position to the holding position. In particular, the elements can be designed such that the sheet material stack is aligned relative to the cutting edge or the cutting edges, in particular centered on them.

In this case, the element or the elements for movement from the receiving position in the holding position can be rotated, tilted or swiveled. As a result, a very large opening can be achieved in a small footprint, in which the sheet material stack to be entbanderolierende can be introduced.

Alternatively or additionally, it is possible that the element or the elements for movement from the receiving position to the holding position is linearly displaceable or are. This embodiment allows a particularly good clamping of the sheet material stack to be entbanderolierenden.

In order to use the Entbanderolierer for sheet material stacks of different thickness, for example, sheet stack with a predetermined number of sheets one for the stack solid but otherwise different thickness, the Entbanderolierer preferably comprise an adjustment means by which the width of the recording on the thickness of or removed leaf good stack is tunable. This is in particular easily possible if the sheet stack is centered by the recording.

As a second alternative, it is possible to dispense with the recording. The transport device can then comprise a holding device for transporting sheet material stacks to be removed from the compartment into the region of the at least one cutting edge, wherein the transport device and the debindering device are designed such that the cutting edge separates the band during the sheet material stack in the Holding device is held. This embodiment is characterized by the fact that a particularly compact design can be achieved. The relative movement between the cutting edge and the sheet material stack required in this case can be achieved by moving the cutting edge, the sheet material stack or both the cutting edge and the sheet material stack, for which purpose the holding device and a cutting device can be designed to be movable with the cutting edge driven accordingly.

For this purpose, the tray is preferably designed so that in this already an orientation of the or the banded sheet stack can be done. For example, the shelf may be inclined relative to the horizontal.

Furthermore, it is also conceivable to continue to use a tray, which serves only for alignment in one direction.

The holding device may in particular comprise a gripper, for example with the already mentioned gripping elements, which removes the at least one sheet material stack to be unbanolated from the compartment and moves relative to the one or more cutting edges.

To remove the severed bands serves a scraper, by means of which the removed bands are taken and fed to a collecting container. The scraper also advantageously emerges between adjacent ones Leaves the Blattgutstapel a to capture the bands reliably. During Entbanderolierens the sheet material stack are preferably on a horizontal inclined backwards tray to avoid, especially when removing the bands dragging sheet material.

Furthermore, a photo station and / or a reader z. B. in Entban- erolierer be provided to capture information on the band photograph or read data on the band, the photos or the read data in conjunction with a code for that compartment in which the associated Blattgutstapel be transported or were stored. This information and data is taken into account during the subsequent sorting of the sheet material. This may be of particular importance when using the subjects z. B. banknotes package are transported deposit-related, so if in the individual compartments very specific Banknotepäck- chen and / or possibly different numbers of banknote packets are transported.

The insertion of the banded sheet stack in the portable compartments can manually or z. B. automatically by means of a robot. The latter is particularly advantageous if a banknote sorting machine with the feeding device according to the invention directly adjoins a cutting installation in which individual banknotes are cut from banknotes and combined into banknote stacks. In this case, the feeding device with the banknote stacks is fed automatically directly from the cutting system.

The invention will be described by way of example with reference to the accompanying drawings.

FIG. 1 shows, as an example of a sheet material processing device, a banknote processing system with a banknote sorting apparatus 1 which serves, for example, for checking freshly printed banknotes and / or checking the condition and / or type (currency or denomination) of used banknotes. The sorting machine 1 is preceded by a Vereinzier 2, by means of which loose stacked banknotes are isolated, so that they can be tested separately in the sorting machine 1. The stacks of loose banknotes are provided in input compartments 13 and supplied to the separator 2 by means of a device 3.

The feeding device 3 in Figure 1 has two transport sections 11, 12, on which the compartments 13 are transported automatically on rails. The upper transport section 11 serves to transport the compartments 13 with the banknotes for Vereinzeier 2 out. The lower transport path 12 serves for the return transport of the compartments after the banknotes have been removed by the separator 2 from the respective compartment 13. Transport units which move the compartments 13 from the upper 11 to the lower 12 transport path or from the lower 12 to the upper 11 transport path are not shown for the sake of clarity. Into the compartments 13 banknote stacks are manually inserted by an operator in the upper transport section 11, as well as an automatic filling of the compartments 13 take place. The Entbanderolieren the banknote stack is then completely automatically.

For unbanding the banded banknote stack (not shown) transported in the compartments 13, a stripper removal station 4 is used. The debandering station 4 is space-saving below a workbench 5 on which Also, the operator console for monitoring and control of the overall process is provided by an operator, housed along the transport path 11. Existing bank note processing systems can be retrofitted without costly conversion with the Entbanderolierstation 4. Not shown are any, the feeder 3 in the transport direction (arrow) upstream facilities. Thus, for example, the compartments 13 transported on the lower transport section 11 can be loaded with banknote stacks directly from a cutting system. If the compartments 13 are filled with loose sheet material, there is the possibility that the stripper removal station 4 is deactivated, since it is not necessary to debranch it for compartments loaded in this way.

Subsequently, the Entbanderolierstation 4 and its operation will be described in more detail with reference to FIG 2. While in Figure 1, the entire system is shown in perspective from the rear view, the section in Figure 2 shows the Entbanderolierstation 4 in perspective from the front. The transport section 11 comprises two parallel, jointly driven transport belts 14, which transport a plurality of carriers 15 arranged one behind the other, of which only one is shown in FIG. 2 and on each of which a compartment 13 for receiving vertically stacked banknotes is mounted. The compartments 13 form the lower part of an input compartment for the Vereinzier 2, as described in more detail in EP 0 764131 Bl. They have a support 16 formed of rods and a back wall 17 also formed of rods arranged vertically, and a lateral retaining wall 18 for accepting the banknote stacks 19, which are manually fed in FIG. 2, with a slight inclination, so that the stack can not slip.

The support 16 and back wall 17 formed by rods make it possible to grasp the banded banknote stack 19 transported in the compartment 13 by means of a rake-type gripper 20 and lift it up out of the compartment 13. For this purpose, the gripper 20 has two comb-like gripping elements, which are supported by through the rear wall 17 so that the lower gripping element under the stack of banknotes 19 comes to lie below the support 16 and the upper gripper element over the banknote stack 19. The gripping elements are then moved toward each other until the banknote stack 19 elements between the gripping of the gripper 20 are securely clamped. Subsequently, the banknote stacks taken in this way are lifted out of the compartment 13 substantially vertically upwards. This state is illustrated in FIG. 2 for five banknote stacks 19, formed by five banded banknote packets each having 100 banknotes.

The movement of the gripper 20 and its rake-like gripping elements is coordinated by a transport device 21, which pivots the gripper 20 with the banknote stacks 19 lifted out of the compartment 13 in the further course of the debandering process by approximately 90 ° such that the banknote stacks 19 are suspended in a hanging State in which they are discontinued by lowering the gripper 20 in a Entbanderolierer 22. There they are kept slip-proof on an obliquely oriented shelf.

The Entbanderoliervorgang includes the severing of the bands, either individually or in groups successively or preferably for all bands simultaneously, and the removal of the severed bands. For cutting is a cutting device 25, the at least one cutting edge and preferably one of the maximum number of transportable in the tray 13 banknote stacks corresponding to 100 banknotes number of juxtaposed cutting edges in order to be able to separate all bands simultaneously. For this purpose, the cutting device 25 is guided along one side of the banknote stack 19 positioned in the receptacle 24, wherein in the illustrated embodiment the banknote stacks 19 are received in the receptacle 24 so that the cutting edges of the cutting device 25 are guided past the longitudinal side edges of the banknotes and thereby between adjacent banknotes can dive to ensure reliable cutting of the banderoles without damaging the banknotes.

On the opposite side of the cutting device 25, a stripping device 26 is provided for stripping and removing the severed bands. The stripping device 26 has at least one gripper or scraper, in the illustrated embodiment one of the maximum number of banknote stack to be processed corresponding number of grippers or scrapers that take the severed bands - here from below - and a ramp 27 in a non-illustrated Dispose of collection container. The bands can also be pulled down in the opposite direction and / or through the tray.

The banknotes stack 19 entbanderolierten in this way are then stacked back in a corresponding manner by means of the gripper 20 in the compartment 13.

The Entbanderoliervorgang can take place in a transport break or during the transport of the tray 13 along the transport path 11. In the latter case, the unbanding station is moved, preferably synchronously, with the moving compartment 13 and then returned to its original position. The Entbanderolierphase is indicated in Figure 2 by the window 28 shown in dots.

While the banknote stacks 19 are located in the receptacle 24 of the depanner 22, information from the bands is photographed by means of a photo station 23. An integrated in the photo station 23 reader also serves to read data from the bands, z. B. by means of a bar code reader or an OCR scanner. The photos and data are then stored in conjunction with a code for an associated compartment 13, for later processing in the separator 2 and / or automatic sorter 1. A preferred embodiment of the cutting device and the receptacle is shown in Figures 3 to 5.

The only partially shown cutting device 25 'has between two arms 30 held at least two, in the example five cutting edges, which are given by arranged on a shaft 31 circular blade 32. The number of knives 32 corresponds to the maximum number of banknotes that can be debanned at the same time, in the exemplary embodiment five. The shaft 31 is driven by a belt drive 46 by a motor, not shown. Thus, the cutting edges are given by rotating about a common axis knives. The shaft 31 and thus the axis are orthogonal to the direction R of a relative movement between the cutting edges 32 and the sake of clarity not shown, held in the receptacle 24 'banknote stack 29 is arranged. The knives 32 therefore rotate about an axis oriented orthogonal to a relative movement between the cutting edge and the sheet material stack. The knives are rotated at least during the separation of the banderole by the drive in rotation.

In the plane of each of the blades 32 is a respective separating element 33, in particular a blade arranged, which is arranged in the direction of taking place for separating the band relative movement R of sheet material stack and cutting edge or knife 32 in front of the cutting edge, so that it between two sheets the sheet pile moves and separates them from each other and the cutting edge is partially moved between the sheets.

The separating elements 33 are formed tapering at its front edge 34. However, the leading edge 34 is dulled so that it can not cut in bills when the cutter 25 'and banknote stack 19 are moved relative to each other to sever the banderole. The leading edges are preferably inclined so that these impact on the Banderole this in the direction transverse to the direction R of the relative movement on the cutting edge, in Fig. 4 so upwards, urges.

The receptacle 24 'has a shelf 35 which is inclined parallel to the direction R and orthogonal to the direction R. Along two longitudinal jaws 36 holding elements 37 are arranged, which on the side facing away from the bottom 35 to the outside, i. away from a receiving area for the banknote stack, are bent in order to facilitate insertion of a banknote stack 19 into the receptacle 24 '.

At the ends, the receptacle 24 'still stop elements 38, which limit a movement of the banknote stack in the receptacle 24' parallel to the direction R and so allow a relative movement between the blades 32 and the banknote stack 19 only.

The course of Entbanderolierens, in particular the severing of the band, is illustrated again in Figures 6 to 8.

The gripper 20, which has two mutually parallel relative to each other by an adjusting device 41 movable gripping elements, sets a banknote stack 19, not shown in the receptacle 24 'while the movable part of the cutting device 25', in particular that shown in Fig. 3 Part, a starting position in which the receptacle 24 'is released.

The gripper 20 then releases the stack of notes, which is held only in the receptacle (see Fig. 7).

After the blades 32 have been set in rotation, the movable part of the cutting device 25 'becomes parallel to the longitudinal jaws 36 of the receptacle 24' and thus the longitudinal edges of the banknotes of the bank to be unbound. note stack 19 method over the banknote stack 19, so that there is a relative movement R.

The front edges 34 of the separating elements 33, which project in the direction of movement in front of the knives 32, respectively separate two adjacent banknotes of the banknote stack or force them apart. The rotating blades 32 then move into the space between the discarded bills and sever the banderole as they hit the banderole. If necessary, forces on the banknote stack 19 are absorbed by the stop 40 lying in the direction of movement R. The stripping is carried out as described above by the stripping device 26, which for this purpose in the example of one of the number of blades or blades 32 corresponding, respectively arranged in the plane of the blade 32 tines 42 includes as a scraper, relative to the banknote stack or banknote stacks be moved against the direction R to strip the severed bands so that they can eventually get into a collecting container 43.

Thereafter, the movable part of the cutting device 25 'is moved back into the starting position and the gripper 20 takes the entbanderolierten banknote stack or entbanderolierten banknote stacks and puts them in the tray 13 from.

Another embodiment, shown in part in Fig. 9, differs from the previous embodiment in the configuration of the receptacle 24 ". All other parts are unchanged, so that the same reference numerals are used and the remarks on the parts apply mutatis mutandis Further, the same reference numerals are used for the same part of the receptacle 26 "as in the receptacle 26 ', and the explanations thereof apply accordingly. The essential difference between the receptacle 24 'and the receptacle 24 "consists firstly in that now the holding elements 37' at the ends of the longitudinal jaws 36, which otherwise correspond to the holding elements 37, by only partially shown drive elements 44, in the example pneumatic cylinder one controllable pneumatic system, driven in a plane orthogonal to the direction R tiltable on one of the longitudinal jaws 36 are held and the other longitudinal jaw 36, designated in Figure 9 with 36 ', with the holding elements 37 in total by only a partially shown drive element 44, in the example On the other hand, the tiltable longitudinal jaw 36 'is linearly movably mounted in a direction orthogonal to the direction R and by at least one further drive element 45, also in the example an electrically controllable Pneumatikzyl indians, drivable.

By means of the further drive element 45, the distance between the longitudinal jaws 36, 36 'and thus the width of the receptacle 24 "can be adjusted according to the thickness of the banknote stack to be unbanolated.

The holding elements 37 'and the holding elements 37 on the longitudinal jaw 36' are tilted into a receiving position prior to inserting the banknote stack into the receptacle 24 "in such a way that their end facing away from the bottom 35 is inclined laterally outwards when the banknotes are separated, they can be easily inserted into the receptacle 24 ".

After insertion, the holding elements 37 'and 37 are tilted into a holding position in which they are aligned at least approximately orthogonal to the bottom 35 and pinch the banknote or stack of notes. The intrinsic cutting takes place as in the previous exemplary embodiment. In yet another embodiment, instead of a receptacle only an optional tray, in the example of the bottom 35 is used. For cutting, the banknote stacks are held by the gripper 20. For this purpose, the arms 30 of the cutting device are made longer, so that the knives 32 can cut through the bands while the gripper 20 holds the pile of banknotes.

If an alignment of the banknote stacks on the tray 35 is to take place, the gripper can be opened briefly before it is severed, so that the banknote stacks are seated on the tray 35 in order then to re-clamp the now aligned stacks. The cutting takes place as in the previous embodiments.

If the compartments 13 are designed such that banknote stacks therein are aligned sufficiently precisely with one another, the stowage can also be dispensed with.

Further, as a variant, it is also conceivable that the cutting device and the stripping device are stationary, and that the gripper 20 moves the banknote stacks for severing and stripping in order to carry out the relative movement.
