Description

8. Rotary printing machine according to claims 2, 3, 4 and 7, characterized in that the electromagnets (127, 102 and 179) of the magnetic couplings (108, 101 or 166) are connected to a stage of the program control.

9. Rotary printing machine according to claim 7 or 8, characterized by a test device consisting of an additional punch card reading head (183) which is connected to the input of a test register (186) and one to the output of the test register (186) and to the second stage (185 ₂ ) of the shift register (185) connected test comparison circuit (211) and a switch-off circuit controllable by this.

The invention relates to a rotary printing machine with at least two printing rollers, each of which carries several rows of rotatable letter rolls and those for printing on each a line of preselected characters alternately on a running paper web to be printed are adjustable in a printing position, for serial printing of products with from series to series changing imprints, such as checks.

In the known rotary printing press of this type (DT-PS 12 41 843), the letter rolls of the respective idle printing roller for printing the next series (s) are set by hand. For this purpose a permanently available manpower is required, and the work requires skill, accuracy and reliability on the part of the operator, since only the limited period of activity of the other pressure roller is available for the adjustment. If the operator does not keep pace with the printing during this work, delays and downtimes of the printing machine would have to be accepted.

The invention is therefore based on the object of adjusting the letter rolls of the respectively inactive Automate pressure roller.

In a known, punched card-controlled printing unit of a typing calculating machine, the letter roll of which is ^{connected non-rotatably for the automatic setting of the same P 1} H ie piiem pinion, a gear drive is assigned to each such pinion, the drive of which is derived from a stepping motor via a long pinion common to all gear drives. An individual toothed wheel of each toothed wheel drive can be pivoted out of its engagement position for engaging and disengaging the associated letter roller with the drive. The number of sub-steps by which a given letter roll is rotated depends on the number of sub-steps of the stepping motor during which the pivoting gear of the transmission is in mesh. The pinion is swiveled in and out under the control of punch cards. The imprint is made by striking the paper over a ribbon against the letter rolls of the printing unit (DT-AS 10 45 133).

Since parts of the drive of the letter rollers are permanently in engagement with their pinions, this is suitable

ίο not apply for this training a rotary printing press. Indeed, this printed work is also for arithmetic and writing Office machines, each of which is a one-time printout of Summan-

x5 den, subtotals and grand totals or the like. Accordingly, control by punch cards with binary encryption is also preferred in this known embodiment.
According to the invention, the set object is now achieved in that for the automatic adjustment of the rotatable type rollers of the respective inoperative pressure roller in accordance with the imprint to be applied to the following series, which is recorded in a known manner on a recording medium such as a punch card, each pressure roller is assigned an adjustment head movable between two positions and each letter roller of each pressure roller is associated with a letter roller pinion known per se and rotatably connected to it, as well as one of several adjustment pinions mounted on the adjustment head, each controllable according to a character of the imprint to be produced, which are in the two positions of the relevant Adjustment head are in or out of engagement with the letter roller pinions, and that in each case the adjustment head assigned to the idle pressure roller is controlled by a control device shortly after the printing of a series by this pressure roller into the E engagement position of the Eüistellritzel with the letter roller pinions and shortly before the end of the printing of the next series by the other print roller can be guided from this engagement position.

This training makes it possible to use a rotary printing press of the type mentioned at the outset to operate that the letter rollers of each idle pressure roller under the control of a Record carrier with any encryption in a time-saving manner on the one in a subsequent one Series to be printed.

This is done with the least amount of parts, because it does not require a multi-part structure Gear drive with an individually swiveling coupling gear for each letter roll or their pinion, but a single one of several setting pinions is sufficient for each letter roll a common adjustment head, can be brought into or out of engagement with the letter roller pinions at the same time are worn. The pressure roller can be completely separated from its adjustment drive, so that the pressure roller is unhindered for rotary printing.

From the above-mentioned DT-AS 10 45 133 it is also known when setting the letter rolls of a Basic position of the same to which, after printing, all letter rolls by means of

Since the machine described, for example, for a card reading device, which is labeled with the collection of printing of five different checks per um- 50 reference numeral 55 and a supply rotation is determined, the printing device 11 has a magazine 56 with punched cards 57 and a punched card, a pressure roller 31 that its scope has five receiving magazine 58. The punch cards 57 rows of letter rolls 32, 33, 34, 35 and 36 carries. are on a delivery track 59 for eleven positions. Each of these rows has 40 pressure rollers when P ₁ , P ₂ - ■■ Pn between the magazines 56 and 58 pushed every print line printed on a check.

should include umpteen letters or spaces. Each punch card 57 contains a piece of information that is arranged under the paper web 1, and the pressure roller 31 is an abutment roller 37 in a global order, each with one of the reference symbols Λ, B, C, etc. In Fig. 3, the rollers 31 and 37 are in working position changeable text, which are shown on a check under pressure, or, with other words 60 of a certain series, are to be printed , th, it is assumed that the printing device 11, for example, it can be seen from FIG of the elementary information a _v a. ₂ , a ₃ and a _{4 are in} operation. the four lines of the check on the

The printing device 11 also has a variable text to be printed 65 and corresponding to

Adjusting head 38, which forms the global information A between two positions along. Each of the zones that

is movably mounted and a series of setting information O ₁ to α, corresponding to the lines,

with six digits enables an information symbol to be encoded in the binary code.

As shown in FIG. 3, the punch card reader 55 has two reading stations 61 and 62 which simultaneously enable two punch cards 57 to be read which pass through these stations and which are each in the corresponding positions P ₁ and p _u . The two reading stations 61 and 62 are located at a distance from one another which corresponds to nine punch cards, that is to say there are nine intermediate stations p ₂ , P ₃ ... P ₁₀ between these stations. So when one reading station 62 reads a punch card, the other reading station 61 simultaneously reads the eleventh punch card in the row of punch cards. Each punch card is read twice in this way, first by the reading station 61 and later by the reading station 62.

The reading stations 61 and 62 are each connected to one of two memories 63 and 64, which are themselves connected to a control circuit 65. This control circuit 65 is at the same time with the adjustment heads, for. B. the adjustment heads 38 and 48 of the group U _{1 connected} in parallel.

In the following a general description of the operation of the device will now be given, and a detailed description of the operation will be given later in the description on the basis of FIG. 16.

In order to simplify the explanation of the mode of operation, it is assumed that each line of the variable text to be printed on the checks comprises only a single letter. In other words, the rows of letter rolls 32 to 36 and 42 to 46 of the pressure rollers 31 and 41 are each reduced to a single letter roll. The mode of operation for the general case of a line consisting of any number of letters can easily be deduced from this. In the same way, only the group U _{x of} the devices 11 and 21 is considered, because the mode of operation of the other devices is the same and is only shifted in time.

It is assumed that in the schematic in FIG. 3, the operating state illustrated in FIG. 3, the printing device 11 is in operation for printing variable texts, denoted by the letters Λ, B, C, D and E , on five series of checks. In other words, the letter rollers 32 to 36 are set in those positions which correspond to one of the information A, B, C, D and E printed on it. The adjustment head 38 is in the rest position, ie away from the pressure roller 31.

In addition, the adjusting head 48 is in its operative position in the printing device 21, in which its pinion 49 is in engagement with the pinion fixedly connected to the letter roller 42 of the printing roller 41. The setting head 48 ensures, as will be seen from the following, the setting of one of the items of information F, O, H, I and / in the letter rolls 42 to 46, which these letter rolls are to print later when the printing device 21 is in Operation is set.

The setting of the information on the scroll rolls of the printing rollers 31 and 41 takes place on the basis of the punch cards 57 which were previously pulled out of the magazine 56. When the information A to / from the letter rolls of the printing rollers has been registered, the corresponding punch cards, which carry the information A, B ... J , are each in one of the positions p ₁₀ , p ₉ . . . P _{1 of} the feed path 59. The information carried by these cards is read as they pass through the first reading station 61, and this information is transferred to the memory 63, from where it is passed through the control circuit 65 for controlling the adjustment heads 38 and 48 in a still to be descriptive

ίο way to be accessed.

At a given point in time, when a check counter (or a programmer connected cyclically with the operation of the machine) determines that the number of printed checks in a series (27 or 52) has been reached, the switching off of the printing device 11 is caused, which is based on this Manner, and the printing device 21 is turned on and begins to print the information F, G, H, I, J on a new series of checks.

As soon as this new printing begins, the letter rollers 32 to 36 must be adjusted so that they can later print on the new variable information K, L, M, N, O , to which one of the letter rollers 32 to 36 must be adjusted. This new information K, L, M, N, O is registered on the punched cards 57, which come from the magazine 56 after the card carrying the information J.

At the moment at which the printing roller 31 is switched off and stops printing, the pinion 39 of the adjustment head 38 is still in the position that determined the last setting of the previous sequence, that is, when the information E was transmitted on the letter roll 36 was done. The mechanism of the device 11 is driven in such a way that when the printing roller 31 is switched off, the following letter roll 32, which previously printed the information A (locally) in front of the pinion 39, is brought to a standstill. The pinion 39 is therefore in the position E, the first letter roller 32, which is located opposite this setting pinion, is in the position Λ, and this latter letter roller must finally be brought into the position K.

This step is brought about in the following way: while the adjustment head 38 is in its rest position (at a distance from the pressure roller 31), its pinion 39 is brought from position £ to position ./4, in order to subsequently engage this pinion with the corresponding letter roll 32, which was brought to a standstill in position A. In order to achieve this, the punched cards 57 are advanced by one step on their feed path 59, so that the card containing the information, 4, _{arrives at position p n} , and that punched card which contains the information K is in the position p, is reached while the intervening punch cards are shifted one step to the right. The card which carries the information A is now read in the second reading station 62, and this information A is transferred to the memory 64. This information is then fed to the setting head 38 via the control circuit 65 in such a way that the pinion 39 is brought into position A.

Then the adjustment head 38 (by a mechanism that is in operation at this moment)

mus) moved into the working position in such a way that supporting information is excited. The letter rollers 32 its pinion 39 with the one with the letter roller 32 are firmly connected to the pinions 32a, with which connected pinions come into engagement, while the adjustment pinions 39 come into engagement, this pinion 39 and this letter roll 32 both the following will be a Embodiment of a corresponding position corresponding to the information 5 printing device, such as the printing device 11, at mation A assume. Moreover, the card hand of Fig. Described in detail to 15 5, contains the information K, in the first reading station, the pressure roller 31, the five rows read to each forty 61, and this information K is stored in memory letters rollers, namely letters rollers 32, 33, 34, 35 63 registered. This information is transmitted via the and 36, is permanently fed to the setting head 38 with a transverse shaft control circuit 65, 10 81 connected, which is mounted with its two ends in two so that its pinion 39 is rotatably mounted about a number of teeth bearing blocks 82, which is rotated in the lateral direction, which is required to bring the pinion to the position K in vertical columns 83 so as to be vertically displaceable. The letter roll 32 will form the frame of the device. The two bearing blocks 82, which are likewise by a corresponding number of teeth, are continuously twisted by means of springs and are located at the end of these bearings to be loaded upwards. The vertical rotation is in a position that corresponds to the imprint movement of the bearing blocks 82 of the printing roller 31 of the information K. is controlled by means of two levers 84.

and this happens during the adjustment periods.

The continuous rotary drive of the printing roller 31 takes place via a gear train to which a gearwheel 103 belongs with helical teeth, which is rotatably connected to the motor shaft 99 and with a large diameter gear 104 is engaged. As shown in FIG. 8 easier to see, is the shaft 81 of the pressure roller 31 rotatably connected to a gear 105, which is connected to another Gear 106 is engaged, which is keyed to a shaft 107 on which the gear 104 means a ball bearing is freely rotatably mounted. A coupling sleeve is displaceable on the shaft 107

108 mounted, which has cutouts 109 and 111 on its two side surfaces. In these clippings

109 corresponding claws 110 can engage, which are firmly connected to the drive gear 104 are. In FIGS. 8 and 14, the coupling sleeve 108 is shown in coupling engagement with the gear 104, so that the latter drives the platen 31 continuously. This position of the coupling sleeve 108 corresponds to the printing time during which the pressure roller 31 rests against the abutment roller 37 under pressure.

As can be seen from the above, when the platen 31 is after printing five Series of checks is to be reset, decoupled from the main drive, that is to say from the motor shaft 99 so that they are then driven intermittently by a fifth of a revolution can be. In this latter case, the shaft 107 is driven, which drives the pressure roller 31, via a gear train, the output gear 112 of which is freely rotatably mounted on the shaft 107 and Claws 113 which are able to engage in the cutouts 111 of the coupling sleeve 108.

The displacement of the coupling sleeve 108 on the shaft 107 is carried out by means of a fork 114 (FIG. 13) controlled, which carries rollers 115 at its ends, which in the circumferential groove or annular groove 116 of the coupling sleeve 108 intervene. This fork 114 is firmly connected to a pivot axis 117. On this A radial arm 118 is attached to the axle, which is loaded by means of a spring 120 and carries a roller 119, those with two adjacent cams, namely a circular cam 121 and a cam with a projecting flank 122, cooperates. These cams are rotatably connected to a shaft 123, which is mounted to be longitudinally displaceable and inside a sleeve connected to a gear 125 in a rotationally fixed manner

124 is guided by a tongue and groove connection. This gear 125 is via a gear train

125 a, 98 b, 100 driven in a continuously rotating manner by the motor shaft 99 of the machine. The end of the shaft 123 is connected to a pivot lever 126 which is driven by means of an electromagnet 127 and is elastically loaded by means of a return spring 128.

Incidentally, an electromagnet 129 (FIG. 15) drives a two-armed lever 131 which rotates about an axis 132 is pivotally mounted and loaded by a return spring 133. The one with a hook shape End 134 of the two-armed lever 131 is in engagement with a pin 135 with the arm 118, which carries the roller 119, is firmly connected.

The mechanism just described works as follows: During a printing period the arm 118 by means of the lever 131 and the hook 134 in the in full lines in FIG F i g. 15 indicated position held. The shaft 117 and fork 114 take one at this time such a position that the coupling sleeve 108 is in its right position for the viewer of FIG is located, in which it ensures that the print roller is driven by the motor shaft 99.

At the end of a printing period, i. i.e., when the platen is to be readjusted, the solenoid is activated 129 energized while the roller 119 engages the projecting flank portion of the cam 122 opposite is located. The pivoting movement of the lever 131 (counterclockwise to the viewer the F i g. 15), which is brought about in this way, has the release of the pin 135 as a result, so that the pivot arm 118 is released. The roller 119 then rolls on the flank of the cam 122 and approaches the axis of rotation of the cams. Incidentally, the electromagnet 127 is also energized, and this has a pivoting movement of the lever 126 for the viewer of FIG. 13 in the counterclockwise direction Consequence. The axis 123 is thus shifted to the right for the viewer of this figure, and the cam with a circular flank 121, the roller 119 is arranged in the transverse plane. This role 119 is under the effect the spring 120 is pressed against the cam 121 and enters the in broken lines position shown in FIG. This has a clockwise pivoting movement of the shaft 117 (FIG. 15), so that the coupling sleeve 108 is shifted to the left (FIG. 14). The claws 113 then engage in the cutouts 111 of the coupling sleeve 108, and from this point on is the shaft 107, which sets the pressure roller in rotation, is coupled to the gear 112. Well can the intermittent rotary drive of the printing roller take place.

At the end of the adjustment process, when the cam follower roller 119 approaches the semicircular flank section of the cam 122 is opposite, the solenoid 127 is de-energized, and this has a Displacement of the shaft 123 to the left (FIG. 13) under the action of the return spring 128 result.

The cam 122 now reaches the transverse plane of the roller 119 and acts on it. Through the protruding Flank section 122 calls this cam a pivoting movement of the arm 118 in Counterclockwise (Fig. 15) emerges, and this pivoting movement is converted into a displacement of the Coupling sleeve 108 to the right (Fig. 14) implemented, and this has the consequence that the shaft 107 with the drive gear 104 is coupled.

Incidentally, the electromagnet 129 was de-energized beforehand, so that when the arm 118 by means of the Cam 122 is returned to the position shown in FIG. 15, this arm in this position is locked by the engagement of the hook 134 of the lever 131 with the pin 135. In this way a locking of the coupling sleeve 108 in the position shown in Fig. 14 during the brought about the whole of the following printing time.

With reference to FIGS. 7, 8 and 12 will hereinafter be an embodiment of an adjustment head and the drive mechanism for intermittently rotating the platen during the Adjustment process described.

The adjustment head 38 (Fig. 7) has a frame

141 on which the shaft 71 carrying the adjusting pinions 39 is mounted. This frame 141 is open mounted on a rockable support, which consists of two arms 142, which are fixed with a transverse axis 143 are connected, which is pivotally mounted on a frame 144. The axis 143 is with two arms 145 and 146 firmly connected, which carry rollers 147 and 148 at their ends, which on a cam 149 or a counter-cam 151 unroll. The two cams 149 and 151 each point on their circumference a series of five projecting and five receding flank sections in such a way that at one full revolution of the cams five complete oscillations of the axis 143 are brought about. The two cams 149 and 151 are firmly connected to a shaft 152 which can be rotated on the frame 144 is mounted and to which a gear 153 is attached.

When an adjustment operation is to take place, the gear 153 and the shaft 152 become continuous revolving driven, and this rotation causes an oscillation of the axis 143 and consequently a alternating movement of the adjustment head 38 with respect to the pressure roller 41 with downtimes in the rest position and in the working position. The adjustment head 38 points inside the frame 141 several electric motors 154, which have clutches and gear trains 155, not shown, the Drive the individual setting pinion 139.

As can be seen from Fig. 7, each adjusting pinion carries 39 two pivot levers 156 and 157 which form part of an electrical safety device. The pinion 39 carries two levers, because the transmission ratio between this pinion and the pinion 32 a of letter roll 32 is equal to 2.

The levers 156 and 157, which are elastically loaded by means of springs 158 and 159, point to their front Each end a nose 156 a, 157 a, which by the action of springs 158 and 159 to the outside are burdened. The lugs 156 a and 157 a act at every half turn of the adjusting pinion 39 on the movable blade of a fixed contact 161 a. This makes it possible to determine the setting pinion to control. Namely, if the electrical signals coming from the contact 161 when passing the nose 156 a or 157 a at a set point in time (the one with the zeroing of a counter, the the position of the pinion 39 is controlled) do not occur, so if an error occurs, the machine remains stand (as will be described below with reference to FIG. 16).

Incidentally, a cutout 162 is provided at a suitable point on the circumference of the letter roll 32. The position of this cutout is chosen so that, when the definition of the letter roll 32 is normal, the cutout 162 can accommodate the nose 156 a or 157 a as it passes through the zone of engagement of the two pinions 39 and 32 a. If, on the other hand, the letter rollers 32 are incorrectly aligned during their rotation, the nose 156 α or 157 α does not fall into the cutout 162 provided, and the nose is consequently pivoted about its axis. This has the consequence that the lever arm 156 b or 157 b protrudes outward and acts on the contact 161, so that the machine is switched off, as will be described in more detail below.
In addition, pivotable fingers 163 are mounted on the frame 141, one of which is assigned to each setting pinion 39. This finger senses the passing of the teeth of the toothing of the pinion 39 and acts on a fixed contact 164, which sends out an electrical signal as each tooth passes, which is used to control the setting of the pinion 39.

In the following, with reference to FIGS. 8 the drive mechanism for the alternating Displacement of the adjustment head and for the intermittent rotation of the pressure roller during of the adjustment process. The drive mechanism has a gear 165, which means a gear with helical teeth 160 is continuously driven to rotate with the Motor shaft 99 is rotatably connected. This gear 165 is with an electromagnetic clutch 166 coupled which, in the energized state, rotates a gear 167 which has a roller 168 wearing. The roller 168 is in engagement with a Maltese cross with five arms 169, so that with each complete revolution of the gear 167 executes a fifth of a revolution.

The Maltese cross 169 is initially through a gear train consisting of the gears 171, 172 and 173, drivingly connected to the output gear 112, which controls the intermittent rotation the pressure roller 31 is generated. With every partial step of a fifth of a turn of the MaI-teserkreuz 169 so the pressure roller 31 also rotates by a fifth of a full revolution further.

The gear 167 is also connected in a rotationally fixed manner to a second gear 174, which is via the gearwheels 175, 176, 177 is connected in a drive-transmitting manner to the gear 153 which is connected to the shaft 152 is non-rotatable, which causes the alternating movement of the adjustment head 38.

When clutch 166 is not energized, gear 167 and all of the mechanism just described are locked by means of a pawl 178 which is driven by an electromagnet 179 which is energized when the adjustment process is to take place.

In the following, on the basis of FIG. 16 describes a modified embodiment of the adjustment device. This device has a punch card reader 55, which consists of a single reading station 181 with two reading heads 182 and 183. Each punch card 57 is read by both reading heads 182 and 183 at the same time. The normal read head 182 is connected to the first stage 184 _{t of} a normal four-stage read register 184 and to the first stage 185 _{Χ of} a shift register 185 of ten stages. The information read by the control reading head 183 is stored in a control register 186. The first stages of registers 184 and 185 and all stages of register 186 are designed in the same way. Each is divided into four basic sections in which the elementary information (e.g. a _v a ₂ , a ₃ and a ₄ ; Fig. 2) corresponding to the four lines of variable text is registered before it is printed on each check of a series. The information is transmitted on four parallel paths in all registers.

The output of the tenth stage 185 _{10 of} the shift register 185 is connected to the first stage 187J _{1 of} a storage

609 637/23

cherregisters 187 connected. The second, third and fourth levels of registers 184 and 187 have three, two or one elementary register, and the reasons for this will be explained in the course of the description explained in more detail.

During an adjustment cycle, the punch cards 57 that come out of the magazine 56 are sequentially is read at the reading station 181 and the information read is simultaneously transferred to the shift register 185 and the read register 184 supplied.

In order to simplify the explanation of the mode of operation, it is assumed that at the beginning of a new setting cycle, the letter rollers 32 to 36 of the previously operated device 11 are set according to the information A, B, C, D and E , while the letter rollers 42 to 46 of the other printing device 21, which was previously out of order and whose setting has just been carried out, are set according to the information F, G, H, I and J. The information A, B ... I, J have been entered into the shift register 185 in sequence, and then gradually moved from one stage to the next in a way that is further described below, so that the information A in the final stage 185, ₀ of the register 185, while the information J is in the first stage 185.

The change in operation of the printing devices, that is to say the alternating bringing the devices into and out of contact under pressure, takes place under the control of a programming device which essentially has two counters 188 and 189 which are connected to a pulse generator 191. The pulse generator 191 sends periodic synchronizing pulses t _v via a first output, the period of which, according to the definition, is the same as that of a cycle of the machine. In a particular embodiment, the period corresponding to the printing of 27 checks is equal to 27 machine cycles, that is to say that 27 pulses i _{t are} sent during this period of time. The pulse generator 191 sends in the same way another series of pulses r ₂ via another terminal, the period of which is equal to half a cycle of the machine. The synchronizing pulses I ₁ and r ₂ are entered at the inputs of counters 188 and 189, respectively.

The counter 188 has a number of levels depending on the number of checks that can be printed in each series. Since the machine in question can print series of 52 checks, the counter 188 has 52 levels. Incidentally, the counter 189 has 99 levels. The individual levels of the two counters are identified with the reference numerals of the counters, to which the order numbers of the levels are appended as an index (for example 188 ,, 188 ₂ ... 188 «; 189 _r 189 ₂ ... 189 ₉₉ ).

At the end of a printing time, stage 188 ₂₇ (series of 27 checks) or 188 ₅₂ (series of 52 checks) of counter 188 is switched on. This triggers a change in operation of the printing device.

The output terminal of the stage 188 ₅₂ (or the level "zero") of the counter 188 is connected to solenoid 102 ,, 129 ,, 127 ,, 179 in a parallel circuit which are associated with 11 of the first printing device that previously for printing in operation was. As stated above, the energization of the electromagnet 102 causes the printing device 11 to be disengaged, while the electromagnets 129 and 127 cause the printing roller 31 to be connected to the drive device for intermittent rotation.

The electromagnet 127 is kept under current for a large part of the cycle of the programming device by a holding _{circuit, which comprises a normally open contact 127, a of} the electromagnet 127, and a normally closed contact 180 _{a of} a relay 180, which is connected to the stage 188 _{24 of} the counter 188 is. In this manner, solenoid 127 remains drivingly connected to the drive mechanism for intermittent rotation during the first 24 phases of the program.

At the beginning of the program, a _{relay 179, which is also connected to stage 188 32} , is put into operation. Its normally open contact 179, _a, is connected in series with the electromagnetic clutch 166, which is excited in this way. This coupling causes ajso that the drive mechanism for the alternate movement of the adjustment head and the drive for the intermittent rotation of the printing device are put into operation. The excitation of the clutch 166 is automatically switched off by means of a contact 166 a, which is actuated mechanically after a full revolution.

In addition, an output pulse of stage 188 ₅ , stage 189, of counter 189 switches on. The output terminal of this stage and the output terminal of stages 189 ₁₀ , 189 ₁₉ , 199 ₂₈ and 199 "are with

an OR gate 192, the output of which is connected on the one hand to a device 55 a of the punch card reader 55, which controls the advance of the punch cards 57, and on the other hand is connected to registers 184, 185, 186 and 187 so that all contained in the registers Information can be shifted by one position. As a result, the information A , which was in the stage 185 _{10 of} the register 185, is transferred to the first stage 187, the storage register 187, while the last information /, which is in the first stage 18S _1, is transferred to the second stage 185 ₂ transformer will. Because of the excitation of the device 55 α wire the following card 57, which carries the information K , moved through the reading station 181, and its information K is read by both reading heads 182 and 183 at the same time. The read head 182 transmits di; Information K on the one hand in the first stage 185, the register 185 and on the other hand in the first stage 184 of the read register 184. The information K is transferred in the same way by the control head 183 to the control register 186. At this point in time, the information A is in the register 187, and the information K is in the registers 18 'and 186 and in the stage 185 of the register 185 contain.

When the second pulse I ₁ passes counter 188, its stage 188 _{2 is turned} on. The output terminal of this stage is with a spoke; Relay 193 connected, which has four normally open contacts, such as contact 193 a, that are branched onto four conductors 194, which are connected in parallel with four parts of the memory register 187.

Since the components of the circuit for the vi groups of printing devices and their W are similar and only different in time, only the printing devices are described below Functions 11 and 21 are assigned to the first group

Since the fourth stage 188 _{4 of} the counter 188 was assumed that the printing device is "switched off, the reading relay 203 is in operation with an even" ordinal number, for example the device, and therefore closes its contacts 203 a. As device 11 has previously been in operation, so it can be seen that at this moment the new EIe relay 205 is in operation, while the relay 206 is 50 mentary information k _v which is in the read register at rest. The bistable multivibrator 204 is located 184 and is now transferred to the equality checker 197 at the output of the stage 188 _{52 of} the counter 188. In addition, the setting head 38 is connected in such a way that the state is brought into its operative position every time the counter is reset (and this is changed by means of the above-described mechanism)

The relay 205 controls two working contacts 205 a 55 pinion 39 is used to engage with the letter

and 205 ε, each of which is brought to one of the conductors 195 and roller 32 firmly connected pinion 32 a.

So if it is assumed that the printing pre- and emits a signal at its output, which is supplied to the direction 11 of the "odd" ordinal number before clutch 74. The setting pinion 39 is in operation at the beginning of the cycle, this is now driven in rotation until the information registered in the counter relay 205 and its contacts 205 α and 207 with the information Ic ₁ 205 b are closed. The contacts 206 a and 206 ft 65 match. On the other hand, when the match of the "even" relay 206 is determined, it is open. When the storage relay 193 closes its contacts roll 39, as described above, to a standstill, the in the first compartment of the is brought to a standstill. So at this point is the information

A _{1 is transferred} from the setting pinion 39 to the letter roller 32 so that the latter is effectively set to the new information Zc ₁ .

This ends a partial cycle of the setting.

When a pulse t ₂ switches on the stage 189 _{10 of} the counter 189 , a pulse is emitted at the output of the latter via the OR gate circuit 192 which, if it is brought into effect on the device 55 α , advances a new punch card 57 containing the information L read in the reading station 181. Simultaneously, the same pulse causes a shift of all in all registers information contained, so that the information B now transfer the storage register 187 and the information K in the second stage 185 'of this register 185 in the first stage 187 _1, and the information L in the first level 185 _X is registered.

The information a ₂ , a ₃ , a ₄ and k ₂ , k ₃ , Zc ₄ are shifted in the second stages 187 ₂ and 184 _{2 of} the registers 187 and 184 for the following setting of the printing device 12 or 22 of the second group.

The above-mentioned pulse U also causes the information K that was previously contained in the control register 186 to be output. This information K is introduced at an input of a control equality checker 211, the other input of which is connected to the second stage 185 _{2 of} the register 185 . The parity checker 211 enables verification that the first reading made by the reading head 182 was correct. If this is not the case, the mismatch between the information contained in stage 185 ₂ and the information output from the control register 186 is converted into a signal output by the equality checker 211 , which is fed to a control circuit via an OR gate circuit 212, which causes the machine to stop.

The device described has further control circuits. In FIG. 16, the output of the “zero” stage of the counter 207 is connected to the input of an and-no gate circuit 213 , the other input of which is connected to the control contact 161 . This contact 161 emits an electrical signal,

ίο whenever it is actuated by the nose 156 a or 157 a (FIG. 7) of a lever 156 or 157 , and this signal should coincide with the output signal of the "zero" stage of the counter 207 . If the agreement does not exist, that is to say if the setting pinion 39 is lagging behind, the gate circuit 213 sends an error message signal which is transmitted via the OR gate circuit 212 to stop the machine.

The error message signal emitted by the gate circuit 213 is also generated when the type roller 32 is out of phase with respect to the setting pinion 39 so that the nose 156a or 157a (FIG. 7) does not fall into the cutout 162 of the type roller. At this point in time, the signal from contact 161 is transmitted via gate circuit 213 to stop the machine.

The control of the other groups of printing devices takes place under the action of the program control, which is formed by the two counters 188 and 189 , offset in time in the same way as described above. The time intervals between the pulses occurring at the relevant output terminals of these counters are determined as a function of the distances between the individual printing devices.
