DE3842583A1 - DEVICE FOR FEEDING DOCUMENTS IN A PRINTING AND / OR READING STATION - Google Patents

Description

The invention relates to a device for feeding Bele into a printing and / or reading station, with feed rollers, tapes or the like Means of transport and with a stop to Align the document received before inserting it into the Printing and / or reading station.

Such devices are in a variety of forms and applications known. A common application is, for example Printing device for printing check forms, however there is comparable devices also for printing other receipts such as driving cards, etc. Pure readers are also known and used by Be Some documents still have to be checked by means of a Reader are performed, so that then both a print station as well as a reading station is available.

It is important that the documents are processed before they are processed be set up so that later printing or scanning with with a read head also in the appropriate place.

It is known to first perform an alignment stop for this hen against which the document can be transported, so that its  Edge an exact positioning for further transport moves. However, it is for the most accurate possible end judge required that the receipt is not through the feeder roll or deformed means of transport, but really comes to rest as freely as possible on the alignment stop. It It is therefore desirable to ensure that the means of transport are supplied the documents are at a distance from the alignment stop, which is larger than the document dimension in this feed direction is. But this means a correspondingly space-consuming Construction.

The invention has for its object a device of the type mentioned at the beginning to create the most space possible is designed to be economical, but with the individual Receipts unaffected by the supply means of transport can be tet and where such an alignment both with horizontal as well as with document feeding from below is possible, in which the document from a lower promoted storage and before reaching the Stop is even bent without aligning There is a bending stress on the document that affects the alignment could endanger.

To solve this problem is the aforementioned direction characterized in that in the feed direction of the Document or the like before the alignment stop. Two in the guideway of the document for this document see and that the means of transport for feeding the Bele after passing the rear one in the feed direction Belegrandes at the junction are reversible and the receipt in the opposite direction at least partially into the switch and the branch of which can be moved back.

In this way, each receipt is received before it is aligned the alignment stop one of the means of transport for his  Feeding independent location, so that for every receipt always the same alignment conditions exist again. It is advantageously aligning regardless of whether the document, for example, in the horizontal direction or closed was fed from below. At the same time this way the feed mechanism is very space-saving be arranged because the transport used for feeding medium from the alignment stop no more than that Document length in the feed direction must have.

An even more space-saving and small-sized device can be created in that the aligning stop (s) can be moved away from the path of the document, for example can be lowered or raised, and when the document is first fed - past the switch - are moved away until the document is moved back again. In this way, the document can first be moved beyond the stop area by the means of transport that serve to feed it, because the alignment stops are initially lowered. Thus, the switch can also be arranged relatively close to this aligning strokes, because the document is then moved back again and is inserted into the switch so that its front edge in the feed direction can then be moved against the aligning stroke again in use.

The feed rollers or the like. Means of transport for the receipt can also in its position that has been moved into the switch tion on its area that still protrudes from the switch grasp and to feed the isolated document from the Serve against the alignment stop. In this way these feed rollers get a dual function, being it usually several feeders on the document feed path roll or the like Can give means of transport and only that Alignment stop next feed rollers this double function  need. These feed rollers can be used for the actual alignment movement a lower speed than for the Have feed.

The alignment stop can be aligned before proceeding transport of the document to the printing and / or reading station can be moved away, vzw. be lowerable.

An embodiment and application of the invention of its own of importance can be protected in a device standing mentioned type exist within a Ausga ATMs for banknotes and / or receipts is arranged where it is even more important for a space-saving arrangement is coming. The corresponding embodiment of the invention can be there in that there is a reservoir for the unimpeded There is provision for separate documents on which separating roles or the like. Attack means of transport that the feed rollers for the isolated document on the alignment stop and the Wei che with a against the feed movement of the document at Printing and / or reading excessive rotation speed are permitted and that in the area of the feed path of the Bele ges sensors, vzw. Light barriers or the like, and at the Alignment stop near feed rollers brakes, vzw. Electromag net brakes are provided on the incoming slip brake at lower speed.

In such dispensers there is also one possible rapid issuance of individual notes, be they banknotes, be it evidence of why the feed speed to the Means of transport is chosen so high that it is off is too high at an alignment stop. The Kombina tion of the switch according to the invention with feed rollers below different drive speeds now allow on the one hand Desired and required in such an automatic dispenser high feed speed on the one hand and that for the  Align significantly lower document feed speed on the other hand towards the alignment stop.

It is useful if a displacement-speed sensor, preferably one equipped with several light barriers Clock disc to measure the speed of the incoming and later decelerated document is provided. To this Way, the signals from the displacement-speed sensor for example, a microcomputer that by means of an appropriate program the brakes, clutch gen and the like. The drive units for the separation and Alignment of the documents can be controlled precisely, so that despite the for aligning reduced feed speed of the Receipt, which can be issued as quickly as possible.

To make the device particularly suitable for automatic dispensers can make the storage container for the receipts below and / or be arranged next to the device and the bele ge can go from bottom to top and / or approximately horizontally feasible and over pulleys and / or transport rollers or -bands on the way to the alignment stop and in front of it sensitive switch. In this way, the front direction as built-in module in its external dimensions to those of egg nes banknote module within an automatic dispenser speak and to the place inside the ATM for issuing and transporting a banknote type tel fit. This means that the device is inside already designed or existing dispensing machines for banks notes can be integrated so that the bank customer on the Vending machine not only cash, but also pre-printed ones Can retrieve checks. Nevertheless, the manufacturer needs the end vending machines no special precautions to fit the device for printing receipts, but to provide only a correspondingly standardized place, like him also provides for one type of banknote. Also  the respective transfer means of transport of rear modules to the output slot can use fin in this way the.

Refinements of the device with respect to the deflection and feed roll in front of the alignment stop and its coupling as well with regard to the drive motors used and also the switch are the subject of claims 9 to 13.

Overall, there is a device for printing and / or reading receipts, which can be very space-saving due to the switch interacting with the aligning switch, but for each receipt - regardless of how it was fed - creates matching alignment conditions and even within a dispensing machine for banknotes fits into the place of a banknote module.

Below is the invention with its as essential associated details based on the drawing in an Aus example described in more detail. It shows in scheme tized representation:

Fig. 2 is a cutaway schematic side view ge an output device for banknotes and Zahlungsbele, within which a device according to Fig. 1 are integrated,

Fig. 3 in a perspective view the essential Tei of the transport means for the document including. Sen le sensors and driving elements,

Fig. 4 is a sectional front view against the feed direction of the document by the feed and alignment rollers with an intermediate document and

Fig. 5 is a representation corresponding to Fig. 4, in which a part of the feed rollers except and only one alignment roll is in operative connection with feed rollers.

A device designated as a whole with 1 serves for feeding documents 2 into a printing station 3 and a reading station 4 . Here are in the embodiment in the device 1 probably a printing station 3 and a reading station 4 hen hen, so that a printed receipt immediately checked who can. The device 1 described below could also be used if only one printing station 3 or one reading station 4 were present.

It is essential that in the feed direction of the document, which is indicated by the arrow Pf 1 , in front of an alignment stop 5, a switch designated 6 as a whole with a switch gate 7 is provided as a branch in the guideway of the document 2 for this document 2 and that the means of transport to be described for feeding the document 2 after passing the rear document edge in the feed direction at the branch can be reversed, so that the document 2 in the opposite direction can at least partially be moved back into the switch 6 and its branch. In this case, the stop or stops 5 for alignment can be moved out of the way of the document 2, can be lowered in the exemplary embodiment, but could also be movable laterally or upward. When the document 2 is first fed past the switch 6 , the stop 5 can be removed from the document path until the document is pushed back again, as a result of which - as already mentioned - it comes out of its original supply path into the switch 6 .

Also in this position moved into the switch 6 , feed rollers 8 with a corresponding counter roller 9 capture the document 2 and serve to supply the isolated document from the surface 6 against the alignment stop 5 which is then again in the use position. Thus, the alignment of a document 2 always takes place from a matching position regardless of whether this document was fed from below, bent and thus deformed or fed horizontally and regardless of the feed speed and also the device 1 can be designed to be very space-saving because the feed rollers 8 u. 9 can be arranged close to the alignment stops 5 , since the coating for alignment is first brought into a special position and only then aligned from this.

After aligning the alignment stop 5 can before Wei tertransport of the document 2 in the printing station 3 or the Le sestation 4 are lowered again, being able to be exploited in an advantageous manner, the mechanism also for moving away of the stop 5 in the first feeding of the document 2 serves.

The device 1 could be used as a stand-alone device in the smallest possible space and be designed with its own housing as a stand-alone device. In Fig. 2, however, a particularly advantageous and expedient application and arrangement of the device 1 is shown within a generally designated 10 dispenser for banknotes and payment documents. At least one storage container 11 for the untreated receipts 2 is provided within this dispenser 10 , on which separating rollers, belts 12 or the like. Attack means of transport. The feed rollers 8 , 13 u. 14 , which transport the isolated document 2 to the alignment stop 5 , are equipped with a rotational speed that is excessive in relation to the advance movement of the document 2 during alignment, printing and / or reading, in order to provide appropriate rotational speeds for the separation and output of banknotes 15 and their drive units to be adapted gate.

Accordingly, in the area of the feed path of the document 2 sen sensors, in the exemplary embodiment according to FIG. 3 fork light barriers 16 , and at the alignment stop 5 near feed rollers 8 brakes, in the exemplary embodiment an electromagnetic brake 17 , are provided, as a result of which the incoming document 2 can be slowed down to a lower speed.

In Fig. 3 it can also be seen that a displacement-speed sensor, in this case a clock disk 18 equipped with a plurality of light barriers for measuring the speed of the incoming and later braked document 2 is seen before.

In Fig. 2 it can be seen that the storage container 11 for the receipts 2 below, according to the dashed representation instead or in addition to the device 1 may be arranged and the receipts can be fed from below upwards and / or approximately horizontally and via pulleys 8 and / or transport rollers or belts on the way to the off reporting stop 5 of the switch 6 in front of it and unto gelan. especially with a reservoir 11 under half of the device 1 can this total with this before storage container 11 as a built-in module in its external dimensions to those of a banknote module 19 maten within the edition car correspond to 10 and machines within the banknote dispensing 10 practically to the place for such from reproducing module 19 medium fit a variety of banknotes and their transport. Thus, the dispenser 10 practically does not need to be redesigned.

Be still ne of the device 1 ben a reservoir 11 for documents 2 with corresponding feed transport means provided - If the stocking is increased with such documents, can - as shown in phantom in Figure 2 is indicated.. Referring to FIG. 2, a main drive motor 27 is provided in the vending machine 10, which causes several timing belt and the timing pulley 23, and thus the separation and feeding of the documents 2 in the pressure / reader. The deflection rollers or feed rollers 8 in front of the alignment stop 5 can be uncoupled from their main drive 27 and the clutch 21 can be controlled by the sensor 16 .

The signals of the displacement speed sensor 18 , the light barrier 16 or the like. Measuring devices can be supplied to a microcomputer, not shown, which can control clutch 21 , brake 17 , reversing the direction of rotation of the feed rollers and the like. A stepping motor 20 is connected for the further transport of the document 2 to the alignment stop 5 , from there into the switch 6 and again to the alignment stop 5 via belt drives with the transport rollers 8 and takes over the transport of the document 2 when its front edge has passed the light barrier 16 , The transport rollers 8 are separated from the main drive 27 and are braked to a lower speed.

Behind the printing and reading station, a further transport device, for example in the form of transport rolls 22 , can then be provided, with which the receipts 2 can be conveyed to an output station 28 .

Referring to Figs. 1 u. 2 can still be seen that the switch 6 is a junction from the direction directed against the usual feed direction of transport of a document 2 upwards and is designed as a curved guideway from the horizontal Füh. As a result, the switch 6 and the receiving space formed by it for an align the document 2 can be arranged within the outline of the entire device 1 , in which the feed path comes to lie from below. Thus, the external dimension of the device 1 in the lateral direction is not affected by the switch and this alternative space for the document 2 to be separated.

It should also be mentioned that a toothed belt pulley 23 belonging to the belt drive only drives the supply or deflection roller 8 and thus also the document 2 when the electromagnet coupling 21 is energized, that is to say it is coupled.

When comparing Fig. 4 u. 5 it can be seen that the shaft 24 provided with counter-rollers to the rollers 8 can be raised. In the 5 shown in Fig. Raised position the counter-rollers have no contact with the feed or guide rollers 8 and the cover, but it is then only the visible in the center, separately mounted and by means of springs 9 a further pressed-aligning roller 9 effective . The other counter roles can therefore not affect the alignment of the document 2 and make it imprecise.

The operation of the device 1 is as follows:

The main drive motor 27 is connected to the separating and feeding transport means for the receipts 2 from the storage container 11 via a belt 25 and corresponding transmissions. Above all, the belt 25 drives the toothed belt wheel 23 , whereby further drives are actuated according to FIG. 3.

The speed or speed of this main drive is far above what is usually permitted for the supply and transport of a document 2 in such devices and in particular when aligning, but corresponds to the transport speeds that are common when issuing banknotes 15 .

In the device 1 it is therefore provided that the running or takeover speed of the document 2 arriving from below or in the horizontal direction is reduced so far that the document can be aligned exactly. Only then can the positionally accurate printing and / or reading on the document 2 take place.

The document 2 coming in from below or horizontally is detected by the light barriers 16 , and the steering rollers 8 connected to the main drive via the magnetic coupling 21 are disengaged. The electromagnetic brake 17 brakes the rollers 8 or the incoming document 2 to a lower speed.

The speed of the incoming and later braked document is measured via the travel speed sensor and its clock disc 18 . The clock disk 18 is slotted in a manner known per se and equipped with one or more light barriers. The signals of this path-speed sensor 18 , as well as that of the light barrier 16 are fed to the microcomputer, not shown, which controls the clutch 21 , the brake 17 , etc. via a corresponding program. Above all via the sensor 18 in conjunction with the light barriers 16 , the end coupling of the rollers 8 from the main drive and the braking by the magnetic brake 17 can be controlled exactly. The further transport of the document 2 is taken over by the stepping motor 20 via a belt 26 ( FIG. 3) and 26 a .

First, the document 2 to be processed, after removal from its storage container 11, is conveyed further in the document running direction or feed direction until its rear edge has completely passed the switch 6 . During this phase, the alignment stops 6 are completely removed or lowered from the path of the document 2 , so that the document 2 can advance freely, for example, up to the transport rollers 22 ( FIG. 1). When the rear or rear edge in the feed direction or the rear edge of the load 2 has passed the switch 6 , the direction of rotation of the stepping motor 20 is reversed and the document 2 is thus transported backwards. Under the action of the switch 6 and its switch tongue 7 , the rear edge of the document 2 is deflected upwards in the direction of a shaft for a return of receipts.

The document 2 is moved backwards until it stops in front of the edge or its front edge before the alignment stops 5 . Then these stops 5 are brought into the transport path of the document 2 , that is, in the embodiment example placed upwards. Now the document running direction is changed again, so switched back to the original "forward" direction. The document 2 then moves under the action of the feed rollers 8 and in the alignment phase only under the action of the middle feed roller 8 and the spring roller slightly resting on this from the alignment roller 9 to the stop 5 . Any slanted incoming documents 2 are exactly aligned by these measures at the stops, so that the front document reference edge is at 90 ° to the main axis, that is to the transport direction.

After aligning the document, the alignment stops 5 are lowered again and the document 2 is transported by the stepper motor 20 into the first print line position. Now the first print line is printed, the print head of the printing station 3 being guided across the document transversely to the document transport direction. Further lines can then be printed or the document can be conveyed further into the reading station 4 . The read head can be arranged on the same carriage as the print head, that is, it can be guided over the document in the same way. After reading one or more lines, the document 2 is conveyed further towards the output of the dispenser 10 , the document being accelerated to the speed of the main drive when it is taken over by a neighboring module. Accordingly, the transport rollers 22 have a freewheel in order to allow them to have a higher speed than them.

The work processes described above can advantageously be carried out in the same way if the document is fed in from below or in the horizontal direction. Even with such devices in which both types of feed exist side by side, there is always a matching starting position of the document at the Wei che 6 for the actual alignment of the document, so that the alignment results always match men.
