Method and device for printing forms

The invention "relates to a method for printing For * · mulars, preferably for bank payment transactions, etc. » where printing e.g. with different, on a print » roller replaceable attachable clichés, especially in intermittent operation of the printing mechanism, and where «-..... Besehich- at the Klisohee by a paint application device; te-t will; The invention also relates to a printing unit for Carrying out the aforementioned procedure. .

There are already printing units known in which the Pruok cylinder carries an interchangeable cliché, which z »B, ußter with the aid of rubber rollers moistened with liquid color Furthermore, printed works are known whose Klisohee with a colored felt roll. Such printing units are, for example, used for imprinting at banks Addresses or the like on payment cards, transfers and the like. Forms used for a specific customer. However, these known printing units have the disadvantage that the

Intermittent operation of the printing unit resulting in practice hinders or prevents trouble-free work. that a permanent operational readiness of the printing unit even after recurring, longer or shorter ones Interruption times is not guaranteed. This depends on the application of paint on the cliché, and also with it together that the printing unit can be operated in a simple, maintenance-free manner by people who have not been trained in printing must and, for example, the paint application device not after the end of a working period or even only in the evening can be maintained.

It should be noted that the colors used for Printing of receipts of payment transactions are used to "dry quickly" so immediately after printing the receipts are already smudge-proof.

Accordingly, the task is to create a Bowie method, a printing unit for printing on forms, that, although it always happens with him after certain more or less long operating times within one! day longer or shorter downtimes and although the operation is carried out by a typographical layperson should the printing process be designed in such a way that that the printing unit is always ready for operation without much maintenance and then practically at

first use works cleanly. In this respect, special requirements are placed on this way of working when the imprint is usually done next to a reading field, 'that is still from a machine document reader can be read. For this reason, the lettering and numbers to be made particularly high demands are made and the process or the associated printing unit must also follow these downtimes and subsequent commissioning work immediately and cleanly. ·

As a solution, the invention initially proposes that, in the method mentioned at the beginning, the color coating of the cliché is done by means of a ribbon. The use has proven to be particularly advantageous an endless ribbon, which is supplied with fresh paint during the work process. Appropriately the ink supply is timed and / or quantitatively coordinated with the scope of the printing activity.

¥ Requests have surprisingly shown that the application of color to the cliché with the help of a Ribbon j 'possibly an endless one, running with fresh Colored ribbon not only leads to a good wetting of the cliché, but this cliché -

neither during long periods of operation nor after downtimes smeared and it comes to unclean prints, nor that downtimes lead to to disrupt the operational readiness. Special maintenance is required when performing the Procedure or when the printing unit is working.

To carry out the aforementioned method, the invention proposes esp. a print with a self rotating printing cylinder, preferably carrying a replaceable cliché, as well as an ink application device for this cliché, the printing unit being characterized in that the inking device has an ink ribbon running past the cliché, preferably by means of a Pressure roller or the like is pressed against the cliché.

It has been shown that such a printing unit is always ready for operation and is practically maintenance-free even the first prints are razor-sharp the area around the printing unit with color or a blurring of the imprint largely avoided. Even the imprint is even on a large number of printed forms.

The diameter of the printing cylinder must be if you want a clean print and an easy job with interchangeable clichés wants to have a certain minimum diameter. Under these circumstances makes the circumference of the cliché usually only a fraction of the total circumference of the printing cylinder. It is advantageous to. if the feed drive of the ribbon is only in The cliché area is where the ink ribbon rests against the cliché. An unnecessary empty transport the ribbon is avoided. The feed rate is expediently based on the circumferential speed matched the cliché. Helative movements between the ribbon, which is usually made of textile material, and the cliché avoided what is especially favorable for the life of the ribbon,

The printing unit can be provided with a finite ink ribbon which can be unwound from a supply reel and, gradually moving past the cliché, can be wound onto a take-up reel. Conveniently, such a take-up reel is provided with a winding drive, preferably od via a slip clutch. The like .. As a result, both the further transport of the ribbon is enhanced and its close-fitting support and clean. ·

In the embodiment according to Pig. 3, the guide of the endless ink ribbon 8a is designed in such a way that it can carry out its advancing movement in the pilgrim step drive. With such a method of advancement of the endless ink ribbon 8a one achieves, for example, that this ink ribbon 8a is guided past the cliché 3 once at the same circumferential speed in the sense of a feed movement in one operation, but then performs a return movement of, for example, 80 # of the aforementioned feed movement. With such a setting of the pilgrim step drive, a certain point of the endless ink ribbon 8a passes the entire length of the cliché in a total of five printing processes. The effective advance of the endless ink ribbon 8a in the area of the re-inking device designated as a whole by 25 is then only the length of 20 $ of the cliché length and with this length one can easily run the width b of a felt strip 26 *), which the endless ink ribbon 8a In the embodiment according to FIG. 3, the ink ribbon runs over the pressure roller 13 in the direction of the arrow Pf 2, first around a guide roller 14 and from there over a swivel roller. 3o, which is mounted on a pivot lever 31. This can execute a pivoting movement according to the double arrow Pf 3, which will be explained below. From there

the endless ink ribbon 8a reaches a further guide roller 32, passes through the post-inking device 251 wrapped around it two further guide rollers 33 and 34 and the tensioning roller 1o. This is located on a clamping lever 11, which has a pivoting movement according to the double? pfeil Pf 4 can perform. From there, the endless ink ribbon 8a arrives at the guide roller 12, which as well as the guide roller 14 rests against the pressure roller 13.

If you want to operate the advance of the ribbon 8a of the printing unit 1a in the pilgrim step drive, this takes place as follows: The advance drive of the endless belt 8a takes place via the pressure roller 13. "The levers 1o and 31 guide with their tensioning or swiveling rollers 1o and 3o a pivoting movement to the left - in Fig. 3. The pivoting movement of the tensioning lever 11 provides the necessary supply of endless tape for the feed, while the pivoting movement of the lever 31, which is controlled by the pressure roller 13 After the end of the rotary feed movement of the pressure roller, this mainly returns to its feed path and the levers 31 and 36 return to the starting position shown in FIG a round of 2o $ of the KI-> schee - length. This corresponds approximately to the

Width b of the pressure plate 73. The first pivoting movements the levers 31 and 11 ex 'follow against a spring force, which move them back into the starting position when the pressure roller 13 returns. The surface of the guide wheel 34 is made rough, e.g. by means of a surface made of foamed plastic. Through this a braking effect in the area of the rollers 34 and 33 is exerted on the ribbon 8a when the Swivel lever 36 moved back into the position shown. The intended, gradual as possible This facilitates the further transport of the endless ribbon. By the aforementioned swivel movements the lever 31 and 36 with the swivel rollers 3ο and 35 is thus to a certain extent a supply of ink ribbon provided for the pilgrimage-like advance of this ribbon 8a.

In Fig. 1 it can be clearly seen that the pressure roller 13 in a lever pair or a fork lever 2o at 28 is mounted, while this lever can pivot about the pivot axis 21. By means of the pen 22 becomes the pressure roller. 13 and thus the ink ribbon 8 or 8a pressed against the cliché 3. Of the The pressure exerted can be adjusted by changing the tension of the spring 22. Adjusting the spring tension takes place via an adjusting screw 29 or the like wax adjusting element for this spring 22.

The re-inking device, designated as a whole by 25, and its mode of operation are good from the Pig. 3, 4a, 4b and 5 can be seen: Around the pivot point 4o 'is a pivotable lever 41 is arranged, which scans a cam disk 42 with a roller 43. By the peder 44, this roller 43 is held in a force-locking manner on the cam disk 42. With the lever 41 An intermediate piece 45 is rigidly connected, at the free end of which one end of a push rod 46 is articulated is. If the printing cylinder 2 rotates in the direction of the arrow drawn there, it is over with 47 and 48 indicated gears the template 42 and thus the pivotable lever 41 and the Rod 46 moves back and forth in the direction of double arrow Pf 5. The rod 46 engages a transmission lever 7o (see. Pig. 5 and 6), which over a shaft (not shown in detail) mounted in the bearing 71 is connected to the lever arm 72. The back and forth movement of the rod 46 results in the pivoting movement of the arm 72 according to arrow Pf 6 in Pig. 4. This lever 72 is designed as a pressure lever for the re-inking device 25 and has in addition a pressure plate 73 · Perner belong to the re-inking device a holder 74 for the mushroom strip 26 and the tank bladder 75 (see. Pig. 3a and 4). Turns the pressure cylinder 2j, the rod 46 exerts a backward and forward movement according to the arrow Pf 5, the lever 72 is pivoted according to the double arrow Pf 6

and the pressure plate 72 moves according to the double arrow Pf 6 (FIGS. 3 and 4) on the felt strip 26 to. The ribbon 8 is pressed against this felt strip and at the same time the tank bubble 75 »which contains dye, something pressurized so that it through its opening 76, dye in the felt strip 26 there. So that this printing process with the desired elasticity calibrated, a spring 78 is provided in the drive path between the levers 7o and 72.

5 and 6 leave the vorbeschrfebene arrangement the guide and swivel rollers 32 to 35 and the swivel arms 31 and 36 in two different Recognize side views well. The pressure lever 72 is in its retracted position when a Ribbon movement takes place, while the ink ribbon 8a is at a standstill, it exerts pressure on the felt strip 26 and the tank bladder 75 in the sense of a pumping movement the end. The pressure force and possibly the elasticity of the pressure movement of the pressure lever 72 are already in the described manner with the help of the spring 78 is somewhat resilient and resilient and this elasticity can e.g. according to the choice or setting of the spring 78 —— be designed to be adjustable in a known manner.

soaked in color

Instead of a mushroom strip 26, there are also / strips made of other absorbent, possibly sponge-like material in question.

A significant simplification of the guidance of the ribbon is obtained by the following development of the invention: An absorbent endless ribbon 8a made of a material or a fabric that favors the distribution of the newly applied color over the length of the ribbon, preferably a ribbon made of cotton fabric. To 26 or the like. Inkpad that after several revolutions of the endless ink ribbon 8a virtually any location is sufficiently provided with paint, forming the width b / ^ _# ^Dr ^ _s ^{ikpla1i1 'e} felt strip. As wide out, that is, with the felt strips 26 ocU like. Sections of the ribbon 8a that come into direct contact are sufficiently close to one another? The aforementioned material property of the color ribbon 8a of distributing color in the longitudinal direction is, if necessary, also used. The above-mentioned special arrangement also includes the fact that the length of the endless ribbon 8a and the required feed length caused by the cliché length are matched to one another in such a way that "taking into account". / the length of the effective color application results in a uniform re-coloring of the endless color ribbon 8a in good time. Tests have shown that color ribbons 8a

30 98 3.9 / 03 U '' -16-

22U793

Made of a suitable material, such as preferably cotton, have a reservoir of color which, without re-inking, allows numerous printing processes without re-inking, depending on the length of the ribbon. The length of the endless ink ribbon 8a and the cliché length should then not be divisible by one another, but rather an offset of the zones acted upon by the cliché should result automatically during normal rotation of the endless ink ribbon 8a. The offset and the storage capacity of the ribbon 8a and the width b de * ¹ pressure plate 73 or the like must then be coordinated with one another.

A coupling is provided between the printing drum 2 and the pressure roller 13, which has at least one rubber jacket. This ensures that the pressure roller only moves in the area of the cliché 3. This has the advantage that the ink ribbon 8 or 8a does not need to move during the entire rotation of the printing cylinder. In the case of the finite ink ribbon 8, continuous rotation would mean that larger ink ribbon sections are not used at all for ink output. In the case of the endless ribbon 8a, the disadvantage of greater wear, in particular the ribbon edges, would arise if this endless ribbon 8a covered practically the same path as the circumference of the printing cylinder 2. Since the length

of the cliché is approximately in the order of magnitude of 1/3 of the circumference of the printing cylinder 2, one can through Interposition of the clutch designated as a whole by K increases the life of the ribbon accordingly enlarge. In addition, there is the possibility of re-inking the ribbon 8a at a standstill. In Fig. 7-9 you can see a clutch housing 5ö * in which a driver 51 is located] its teeth 51a engage with the appropriate shift in the gear 53 and are in a known manner, for. B. by the choice of tooth shape, held there until it disengages. By connecting the gear 53 with the driver 51 causes a rotary movement of the clutch housing 5o and the gear 57. The clutch housing 5q is firmly connected to the Ji / elle 1o1, as can be seen from Fig. 7; accordingly it rotates according to the sequence of movements of the printing unit »" ■ with are indicated on the clutch housing 5o arranged springs which act on the driver 51 · and in the direction the arrows 11 draw. The engagement of the driver 51 takes place just in time that the pressure roller 13 begins to rotate in front of the area of cliché 3. In terms of transmission technology, this becomes the following. ' mass realized: By'den concentrically to the shaft 1o1 (Fig. 8) adjustably arranged engagement cams .11 ο there is a pivoting of the pawl 111, so that their Naoe 111a unlocks the driver 51. He will then

A switch-off wedge is denoted by 54 and a switch-off cam is denoted by 6o (FIG. 8). These cause the driver 51 to be released from the driver gear 53. The switch-off cam 6o (see FIG. 8) is to be accommodated in such a place that the uncoupling process takes place when the cliché the pressure roller 13 has passed. In Fig. 6 it can still be seen how the gear 57 into the gear engages, which sits on the shaft 61 (Fig. 2). The gear 57 meshes with this gear.

From FIG. 2, the flow of force can be seen in accordance with the lines there that are more strongly drawn out and provided with arrows. The drive starts from arrow Pf 2o and leads via gears 47 and 48 to clutch K. On the shaft 1o1 (FIGS. 2 and 3) there is both the pressure cylinder 2 and the coupling elements described above, as well as the associated gear 57 The meshing gear 58 then transmits the rotary motion of the gear 57 to the shaft 61 and thus to the pressure roller 13.

Pur the mentioned drive of the pressure roller 13 according to the pilgrimage method is used appropriately., Gear arrangements, not shown here, which have a greater propulsive movement than the subsequent Cause backdrive movement. This pilgrim step drive movement in the sense of the feed is then synchronized with the run of the ribbon over the cliché, while the return in the remaining time can take place where the ink ribbon 8a does not have to exercise any inking function on the cliché 3.

for the drive, provided in the pilgrim step, but for an intermittent movement determined by the length of the cliché. The drive movement adapted to this has already been described above. The elimination of the pilgrim step drive in the case of the endless ink ribbon 8a simplifies its guidance. From the pressure roller 13, the ink ribbon 8a reaches the guide roller 14, from there to a pivotable tensioning roller 3o, from there to a further guide roller 32, then passes through the re-inking device 25 »wraps around the further guide roller 33 and. passes from this directly to the guide roller 12 adjacent to the pressure roller 13.

Serving roller 3o is mounted on a pivotable lever 31 which can pivot again according to the double arrow Pf 3 and is connected to a spring for this purpose. This maintains a permanent tension on the ink ribbon 8a. One can dispense with the pilgrimage-like advance of the endless ink ribbon 8a if certain conditions are observed in the manner already mentioned. If one denotes the length of the endless ink ribbon with L (Fig. 11) and the circumferential length of the cliché 3 with 1 (Fig. 1), then L / ^ must not result in an integer; Offset of the respective zone coming to the cliché. The offset must be large enough so that the ribbon does not have to color the cliché 3 too often at one point without re-inking. The offset of about 2o i "at pilgrim step referenced by this. In addition, the length of the ribbon and the width b of the pressure plate 73 or the width of the felt strip 26 or the like must be matched to the length L of the ribbon, analogous to the aforementioned coordination: If, for example, an endless ribbon 8a without re-inking 15 times a cliché 3 can be provided with sufficient color, it must be ensured that every section of the ribbon has been re-colored no later than the 15th pass of the ink ribbon 8a through the re-inking device ^.
