Description

The invention relates to a method for the automatic control of die setting and line casting machines with the help of z. B. information stored in a punched tape, in which the entered Information is first stored and then the required delay time until it is passed on of the information to the typesetting machine is determined as a function of the preceding information will.

In a known punched tape control of die setting and punching tape that works according to this method Line casting machines become control elements in accordance with the information scanned by the punched tape preset. This setting is transferred to selector rails. This leaves the control command for the jig stores according to the scanned information until the next row of holes is scanned and is evaluated for presetting. The transfer of the information to the typesetting machine is delayed to varying degrees. This is especially true for double characters, i. H. two of the same consecutive Characters, or for rail switching. Around this delay depending on the type of character to be able to choose different, an additional transmission gear and a timing gear are provided, which takes over the control when the relevant characters appear in the registration strip (DT-AS 1 116 236). - According to this known procedure examines whether the last scanned character matches the previous character, also whether it is a character that requires a delay regardless of the preceding character, z. B. to operate the elevator or to move the switching rail. However, the choice of Delay no more than two consecutive characters compared with each other.

With this method of control, it is possible to increase the setting speed to the extent that the normal cycle time in which two commands for normal functions may follow one another, the time for half a turn of the eccentric shaft in the keyboard plus a safety time. Under normal commands are understood to be those that trigger different successive commands Command matrices or control machine functions that are completed in a relatively short time. Before passing on unusual commands, especially to trigger a second identical command Matrix (double character), the delay is provided in the case of the double character of a cycle time is equivalent to. However, it is not possible to increase the setting speed any further, as this would cause interference occur on the jig.

The same applies to the essentially identical, only slightly varied known methods for controlling die setting and line casting machines. One of these is state-of-the-art belonging processes, the successively scanned information is differentiated according to whether at If double characters occur, two identical matrices should be triggered, the triggering being delayed is, or whether the successively scanned information is inoperative, in the latter case a The acceleration circuit becomes effective (FR-PS 1 412 150). - be similar after a varied known method, the scanned information is evaluated individually afterwards, whether it delays itself claim. This applies, for example, to the commands »Return«, »Additional space«, »Elevator«. In addition, each piece of information is checked for equality with the previously scanned information. The ineffective code characters are determined, and when they occur one after the other unlike double characters, the trigger two identical matrices one after the other (GB-PS 946 716).

The present invention is based on the object of automatically controlling the setting speed Die setting and line casting machines beyond the previously permissible level without disrupting the setting machine to increase.

This object is achieved with the invention as indicated in the main claim.
This allows the setting speed to be increased further. It is possible to shorten a release cycle for two normal, consecutive commands to about a third of the rotation time of the eccentric shaft plus a safety margin. This is possible due to the fact that not only the increased time required for double letters, but also when two pieces of information separated from one another by a third piece of information, e.g. B. to trigger the two letters "e" in the word "go" is recorded. In the latter case, too, there is a pause before the second die with the same typeface is triggered.

In a particularly expedient development of the method according to the invention, before it takes effect a shorter delay is provided for the second identical information for triggering a die than when two such pieces of information follow one another immediately. - This results in There is a further increase in the setting speed, since the time before the triggering of the second same die so that it can be kept as short as possible without causing interference. It will takes into account that due to the other information in the second position there is anyway a time gap between

see the triggering of the two matrices with the same Characters or the release of other comparable information occurs. This time interval however, it is not sufficient for a trouble-free release of the second die with the same character off when the setting speed by a rapid succession of the information scanned one after the other for more problem-free commands, especially for triggering matrices with different characters, is very high.

The invention is explained in more detail below with reference to a drawing with two figures. It shows

F i g. 1 shows a perforated strip used to control a die setting and line casting machine in a simplified form Form with only three information tracks, as well as a tabular overview of the means of this Perforated tape on the setting machine to effect functions and

F i g. 2 shows a logic circuit diagram of an arrangement for carrying out the method according to the invention.

F i g. 1 shows 12 steps that are on the left edge of the figure with 4 to 15 are designated, on a vertically illustrated punched tape 18, the three information tracks 19, 20, 21 and a cycle and transport lane 22 has. To the right of the punched tape are three columns 23, 24, 25 arranged side by side. Column 23 denotes the type of command in the punched tape, column 24 the on function to be triggered by the setting machine and column 25 the delay time before the function is triggered.

In the case of the FIG. 2 illustrated logic circuit diagram of an automatic setting machine, in which details not of interest here are not shown, the group A of circuit elements bordered by simple dotted lines means a reader for punched tape, which in this exemplary embodiment works photoelectrically in a known manner. Group B , which is also bordered by a single dashed line, represents a first memory for the information retrieved from the punched tape. Group C accordingly means a second memory, group D a first comparison device, group E a second comparison device, group F a test device for special information, group G a control device for triggering and tape transport, group H a timer, the group / a decoding device, the group K a triggering device to send the evaluated information to the typesetting machine z. B. to be electromechanically effective.

In group A , the punched tape 18 with the information tracks 19, 20, 21 and the transport track 22 are shown. The punched tape is moved by means of a roller 42 which is driven by a motor 43. The punched tape information (in the form of one or more holes) is scanned photoelectrically in that the light from a light source 44 falls through one or more of the holes in the information and transport tracks 19 to 21 onto the corresponding photocells 45 to 48, generating information which are inverted in the information tracks in the inverters 49,50,51, so that positive and negative information is available at the output of the reader for the code. The signal from the photocell 47 assigned to the transport track is given via a pulse shaper 52 in order to generate a pulse at the output when the punched tape reaches the exact reading position.

In the group ß are the three information tracks 19 to 21 the bistable members 53, 54, 55 assigned, which in turn have the outputs 36, 37, 38, their activation means that there was a code hole in the relevant information track. These bistable When corresponding code information is available, links are activated via the photocells 45, 46, 48 switched on via UN D gates 56, 57, 58, whereby they save the code information.

Here are 36,37,38 at their outputs appropriate information. If there is no code information, the bistable elements become 53,54,55 via the inverters 49,50,51 and other AND gates 59,60,61 deferred.

Group C shows, as mentioned, a further information memory, which consists of the bistable elements 62,63, 64, which analogously to the above, the information from the memory B when activating the AND gates 65,66,67 or 68,69, 70 take over. The corresponding information appears at the corresponding outputs 39, 40, 41.

Group D reproduces a comparison circuit which compares the information on the photocells 45, 47, 48 or the inverters 49, 50, 51 with the information in the memory C in the bistable elements 62, 63, 64. Here, the outputs of both reader A and memory C are crossed to AND gates 71, 72, 73, 74, 75, 76. If the information is not the same, a signal occurs on the output side at at least one of these gates. As a result, all outputs of the UN D gates 71 to 76 are led to an OR gate 77, at the output of which information is always generated when the information in reader A and in memory C differ from one another.

In the case of group E , an analog comparison circuit between the memories B and C is shown, with the outputs of the memories B and C also being routed crosswise to AND gates 78, 79, 80, 81, 82, 83, via an OR gate 84 then also deliver an output signal if there is no tie between the memories ß and C.

The group G , as mentioned, represents a control device for transport and release. The motor 43 is controlled by means of a bistable element 89, which in turn either via an OR gate 90 from the timer described further to group H , inversely to output 29 or is switched on from an AND gate 91 and information from output 27 can reach the motor 43. The AND gate 91 then emits an output signal when the inverters 49, 50, 51 show a signal, that is, there is no code information in the punched tape that would have to take effect on the typesetting machine. Another piece of information, inverse to that at output 28, is received by this AND gate 91 from timer H. As a result, the transport of the perforated tape 18 is switched on immediately after a code combination has been recognized which has no function on the setting machine. The transport is switched off by sending a switch-off pulse to the bistable element 89 via the photocell 47 and the pulse shaper 52 when a hole is read again in the transport track 22 on the punched tape 18. With a correspondingly low-inertia design of the drive, consisting of roller 42 and motor 43, the punched tape can be stopped precisely in its reading position in this way.

An AND gate 92 is connected to the inverse output of the bistable element 89, the OR gate 77 and the timer H, via which a bistable

Member 93 is switched on when, after the end of the paper tape transport, the comparison circuit D does not find a tie between the memory C and the paper tape code. The inverse output of this bistable element 93 releases a NEITHER-NOR gate 94. The NEITHER-NOR gate 94 also receives the inverted information from the OR gate 84 and from the output 29 of the timer H. The inverse output of the bistable element 93 means that a short delay time must be inserted before the information takes effect on the setting machine . The output of the WEDER-NOR-gate 94 therefore provides information when the bistable element is switched on after the reader 93 has been shut down, because there is no match between reader A and memory C, the corresponding time condition is present via output 29 from the timer //, and there is no information from gate 84 that a delay is to be introduced before the signal takes effect on the setting machine. The output signal of the WEDER-NOR gate 94 goes via an OR gate% and a further AND gate 97 to the input of a bistable element 98, at whose output 34 the information arises that the signal can be effective on the setting machine. In addition, the timer H becomes effective according to the information available and resets the bistable element 98 via an OR gate 99 after the specified time.

The timer according to group H has an input-AND-NOT gate 100, the positive input of which is connected to the inverse output of the bistable element 89 and the negative input of which is connected to the output of an OR gate 101. This gate receives the information from output 34 of the bistable element 98, which also resets the bistable element 93. The other inputs come from the outputs 29, 30, 31, 32 of the timer H, which are assigned to timers 102, 103, 104, 105. The OR gate 101 thus supplies an output signal when one of these timing elements 102 to 105 or the bistable element 98 is in the working position, so that the AND-NOT gate 100 supplies an output signal when neither one of these elements 102 to 105 and 98 the bistable element 89 is still switched on. In this case, a timing element 106 becomes effective, which causes information at its output 28 during its own time or sends the information that is inverse to this to an AND-NOT gate 107 and to the AND gate 91 already mentioned. The AND-NOT gate 107 is also connected to the AND gate 91 and to the pulse shaper 52 and outputs information when the punched tape 18 is in the reading position, the timer 106 resets itself after its time has expired and none at the Setting machine ineffective information about the AND gate 91 is present. The timer 102 is switched on, the contents of the memory B are also transferred to the memory C via the AND gates 65 to 70 and the code signal from the punched tape 18 via the photocells 45 to 48, the inverters 49 to 51 and the AND Gates 56 to 61 are transferred to memory B. As mentioned above, the timer 102 sends a signal to the WEDER-NOR gate 94 and the OR gate 101 via output 29. After its time has elapsed, the timer 102 sends a signal to an AND gate 108, the OR Gate 90 and an AND gate 109. The AND gate 108 receives a second piece of information via an inverter 111 from the OR gate 84. So if the information of a double-letter delay or a long delay is present, one obtains at the output of the AND gate 108 is information that switches on the timer 103 via an OR gate 112, which in turn sends information to the OR gate 101 via output 30. After its time has elapsed, the timer 103 sends a signal to an AND gate 114 If there is information for a long delay, a signal is produced which switches on the timer 104, the output 31 of which sends information to the OR gate 101. After its time has elapsed, the timer 104 sends a signal via the OR gate% and the AND gate 97 to the bistable element 98 and thus makes the signal effective on the setting machine. The bistable element 98 sends a signal to the timing element 105 via output 34 and switches it on, which in turn sends information to the OR gate 101 via output 32. After its time has elapsed, the timer 105 sends a signal to an OR gate 112, which switches the timer 103 on again. After the time of the timer 103 has elapsed, a signal arises at the output of the AND-NOT gate 113 which resets the bistable element 98 via an OR gate 119, an AND gate 120 and the OR gate 99.

Group / shows a decoder consisting of the AND gates 121, 122,123,126,128. The AND gates have the task of following the code according to FIG. 1 to decrypt encrypted information. For this purpose they are connected to the outputs 36,37,38 or the inverse outputs of the bistable elements 53,54, 55 of the memory B ; long the command on the setting machine takes effect.

Group K, which comprises a triggering device, to the evaluated information on the setting machine z. B. to be electromechanically effective, has as actuators electromagnets 132, 133, 134, 136, 137 and 139, which are controlled by signals that come from the outputs of the AND gates 122, 123, 126, 128.

For further explanation of exemplary embodiments, some functional sequences are intended below are portrayed.

If in Fig. 1 a code is read in step 4 which is intended to trigger a die without first to switch on a delay time, this is to be regarded as a normal case, which proceeds as follows:

First, by resetting the bistable member 89, the transport of the perforated tape 18 is stopped and the timer 106 is switched on. After its time has elapsed, this timer sends a signal to AND gates 56 to 61 via AND-NOT gate 107, whereby the code information read from the punched tape is transferred to bistable elements 53 to 55 of memory B. If the code shown in step 4 receives signals at the outputs 36 and 38, the AND gate 121 can switch on the magnet 132 as soon as this AND gate receives a signal from the bistable element 98 via output 34. The bistable element 93 and also the j timer 102 are switched on via the AND-NOT gate 107 and the AND gate 92, with a release signal from this timer 102 after the expiry of the j in electronic setting machines, an extremely short time is given via output 29 to the WEDER-NOR gate 94. Since in this case we are dealing with a normal matrix, ie no special time conditions need to be observed and this matrix is also not of the same type
