Definitions

  • the invention relates to a control device for a machine for applying glue strips by means of nozzles on paper webs which, after gluing, are divided into the individual formats of form sets by means of a transverse perforation cylinder, with a displacement sensor which measures the path covered by the form set, a control circuit with a memory device which stores an adjustable value for a glue strip start and a second adjustable value for a glue strip end, and a determination device which emits a signal «glue when the value assigned to the glue strip start is reached and a signal « non-glue »when the value assigned to the glue strip end is reached, and an output stage controlled by the control circuit for switching on the glue nozzle in response to the "glue" signal and for switching it off in response to the "non-gluing" signal.
  • Such a control device is known to those skilled in the art in the form that a position sensor disc is used which is connected to the axis of the transverse perforation cylinder.
  • the surface of the position sensor disc has aluminum strips attached in the form of a segment of a circle. These aluminum strips are scanned by induction sensors as they stretch.
  • Each induction transmitter is connected to a control circuit, via which the output stage for an associated glue nozzle is controlled.
  • the length and position of the aluminum strips is selected so that a format sample is glued in exactly the right place by the glue nozzle controlled by the induction transmitter.
  • the length and position of each aluminum strip is to be determined empirically.
  • Such a known control device is very labor-intensive in its use for changing format patterns.
  • it is necessary to operate a position sensor disk for each nozzle.
  • Different position encoder disks must be used for different patterns. This leads to a large number of position encoder disks to be kept in stock and to a large conversion effort.
  • the position encoder disks When switching from a format of e.g. B. 8 inches (20.32 cm) on one of e.g. B. 12 inches (30.48 cm), the position encoder disks must be rotated in their relative position to the transverse perforation cylinder, even if the relative dimensions of the adhesive pattern remain constant.
  • a control device for a similar purpose namely for gluing objects moving on a conveyor belt
  • DE-A1 29 02 319 A control device for a similar purpose, namely for gluing objects moving on a conveyor belt.
  • the device requires a counter and a memory for each glue strip start and for each glue strip end.
  • the memory content must be set manually.
  • a very large number of counters and memories are required, all of which must be set precisely by hand. As the number of stored values to be set increases, however, the risk of incorrect entries increases.
  • the invention has for its object to provide a control device of the type mentioned in such a way that changing the position and length of at least one glue strip on a format of continuous form sets is possible without considerable retooling work with great operational reliability.
  • the control device has at least one transducer to be attached to the machine for ascertaining the positions to be glued in a format which emits a signal for each start and end of a glue strip to be applied, as is marked on a reading format, of which a specific one, by the Counter device corresponds to the number of increments counted when the signal occurs, which is automatically stored as an increment number assigned to a glue strip start or end when the signal occurs from the transmitter during reading in the memory device.
  • the parts of a format to be glued are first marked on a reading format, e.g. B. by metal strips. At the beginning of a work cycle, this reading format is placed on the uppermost of the paper webs to be glued together and is then guided past the sensors with the transported paper web.
  • the transducers then, for. B. by inductive measurement, whether or not an aluminum strip is present depending on the path determined by the displacement sensor. This presence or absence of the aluminum strip is stored in a computer read-in process at the beginning of the work step. Then the computer is switched to the "gluing" operation. Depending on the path then taken by the formats to be glued, the Computer via the output stages of the glue nozzles the signal for gluing or for non-gluing. This signal is issued depending on whether or not there was an aluminum strip at the appropriate point in the first step, "Reading in”.
  • reading the punch cards initially only defines the point in time for initiating any control processes with respect to an as yet unspecified starting point.
  • a starting time of the machine must first be made to coincide with the starting time for the read values.
  • the control device not only has the advantage that conversion work is almost completely excluded, but compared to previously known control devices, it is also possible in the simplest way to compensate for dead times of the glue nozzles.
  • Fixed dead times can be compensated for by adding a value to the travel value determined by the travel sensor, which corresponds to the distance traveled by the paper webs during the fixed dead time. This measure controls each glue nozzle by the dead time before its actual switch-on or switch-off time.
  • a dead time address transmitter determines how much distance from a paper web is covered during a predetermined dead time. This path is then added to the path actually covered by the paper web. If the paper web runs faster, the distance covered during the dead time is longer, if it runs slower, the distance is shorter. As a result, a glue nozzle is switched on or off earlier when the paper web is running fast than when the paper is running slowly.
  • a control device which takes into account the dead times in a similar manner is known from DE-A1 29 02 319 already mentioned at the beginning.
  • the switch-on dead time of glue nozzles is generally shorter than their switch-off dead time.
  • Such different dead times can also be compensated for in a simple manner with a control device according to the invention. For this purpose, it is determined which path is covered by a paper web or a format during the switch-on dead time and which path during the switch-off dead time. These values are added to the actually traveled value. It is then determined whether a value for the two addition path values is stored in the computer which indicates «glueing or « non-gluing crochet The glue nozzles are only activated via the output stages if the value «glue» is displayed for both addition path values. This measure ensures that different switch-on and switch-off dead times for glue nozzles are compensated for regardless of slow or fast-running paper webs.
  • the glue machine with control device shown in FIG. 1 has, inter alia, three paper rolls 10 with printed paper webs.
  • the three paper webs 11.1 to 11.3 are guided over deflection rollers 12 so that they finally come to rest on one another.
  • the paper webs are glued in places via glue nozzles 13.1 and 13.2.
  • the paper webs are aligned with one another in such a way that the associated format patterns are exactly congruent with one another.
  • the format samples glued together in this way are then divided by a transverse perforation cylinder 14 with knives 15 through transverse perforations into the individual formats of the endless set.
  • the endless set is then folded, but this is no longer shown in FIG. 1.
  • the transport device for the paper webs is also not shown. The transport is usually carried out via perforations in the longitudinal edges of the paper webs.
  • the control device also shown in FIG. 1 has a computer 16, two sensors 17.1 and 17.2 and a displacement sensor having a toothed disk 18 (FIG. 3).
  • the circumference of the transverse perforation cylinder 14 corresponds to an integral multiple of a format length.
  • the transverse perforation cylinder 14 is provided with four knives 15, which corresponds to a circumferential length of four formats.
  • the toothed disc 18 is fastened on the axis 19 of the transverse perforation cylinder.
  • This fixed assignment between the toothed disc and the transverse perforation cylinder and, on the other hand, the fixed relationship between the circumference of the transverse perforation cylinder and a format length means that there is also a fixed relationship between the number of teeth rotated past a fixed point and the longitudinal position of a format with respect to a fixed point in the paper running direction 20 seen exists.
  • the fixed point from which the number of teeth rotated past is determined is determined by a particularly deep slot 21 in the toothed disk 18.
  • the toothed slots 22 of the toothed disk are made less deep than the slot 21.
  • two light sources 23.1 and 23.2 are arranged such that one, 23.1, can only shine through the deep slot 21, while the second light source 23.2 all slots can shine through.
  • two photosensitive elements 24.1 and 24.2 are arranged behind the toothed disk 18.
  • the light-sensitive element 24.1 receives the light that has passed through the deep slot 21 from the light source 23.1.
  • the light-sensitive element 24.2 receives the light which has passed through the slits 21 and 22 from the light source 23.2.
  • the photosensitive element 24.1 is connected to a zero line 25 and the photosensitive element 24.2 to an increment line 26 with the computer 16.
  • the meaning of the transducers 17.1 and 17.2 will now be explained with reference to FIG. 2.
  • the transducer 17.1 is, as indicated by the dashed line 27.1, seen in the paper running direction 20, at the same height as the glue nozzle 13.1. Accordingly, the transmitter 17.2 is at the same height as the glue nozzle 13.2.
  • a hatched reading format 28 is placed to cover the exact format.
  • This reading format 28 has an aluminum strip 29.1 exactly over the length over which the glue nozzle 13.1 is to glue. If the paper webs 11.1 to 11.3 are moved in the paper running direction 20, the reading format 28 and with it the aluminum strip 29.1 passes under the sensor 17.1.
  • the sensor 17.1 is designed as an induction sensor and thus determines whether or not the aluminum strip 29.1 is passing under it. It sends this information to the computer 16 via the encoder line 30.1. As already described, the computer 16 simultaneously receives information via the increment line 26 as to which path a format has traveled.
  • the number of teeth of the toothed wheel 18 rotated past the photosensitive element 24.2 is counted up from zero, the zero value being determined by the deep slot 21. While it was necessary in the case of displacement sensors on previously known control devices that the format start 31 of a format to be glued, which is identical to the format start of the reading format 28 in FIG. 2, had to be present at the first glue nozzle 13.1 when the displacement sensor showed the value zero , this is no longer necessary in the present case.
  • z. B already counted ten teeth when the format start 31 is above the glue nozzle 13.1 and the transmitter 17.1 shows z. For example, if the 35th tooth is to be glued, this value remains in the computer for all other continuous formats saved.
  • Alignment of the toothed disc 18 by rotating about the axis 19 to adapt to the format start 31 is therefore no longer necessary.
  • the toothed pulley 18 according to FIG. B. 480 teeth. With four formats per revolution of the transverse perforation cylinder 14 and thus of the toothed disc 18, 120 teeth per format length are thus available. A correspondingly higher or lower number of teeth can be used for greater or lesser path accuracies.
  • the first format has to be glued from the 35th tooth, the following format from the 155th tooth, the third format from the 275th tooth and a fourth format from the 395th tooth. In the following format, glue is applied again from the 35th tooth.
  • the control device in FIG. 1 has two working steps.
  • the first step is “reading in”
  • the second step is “gluing”. If the control device is set to “reading in”, the measuring sensors 17.1 and 17.2 determine positions to be glued later and enter their measured values into the computer via the sensor lines 30.1 and 30.2.
  • the computer 16 sends control signals to the glue nozzle 13.1 or 13.2 via control lines 32.1 and 32.2, specifically via the path sections which had previously been determined when reading in as provided on the reading format 28 with aluminum strips 29.1 and 29.2.
  • control devices 33 are shown in more detail.
  • the control device has the computer 16 as the central device.
  • the zero line 25 already described and the increment line 26 are connected to a control logic 34 in the computer, with which an operating panel 35 is also connected via an operating line 36.
  • the command “read in” or “glue” can be given via the control panel 35.
  • dead times can also be entered via the control panel 35.
  • at least one sensor 17 is connected to the computer 16 via a sensor line 30.
  • the encoder line 30 leads to a RAM memory 37. Outputs from the computer 16 lead to an output stage 38 which controls the glue nozzle 13 via the control line 32.
  • the computer 16 has, in addition to the control logic 34 and the memory 37, an increment counter I which is also connected to the increment line 26 and is connected to the control logic 34 via a RESET line 39.
  • the counter I is connected to the memory 37 via an address line 40.
  • the memory is connected to the control logic 34 via a read / write line 41.
  • the data output of the memory 37 leads to the output stage 38 via an output line 42.
  • the command “read in” is first given on the control panel 35.
  • the control logic 34 sets the counter I to zero via the RESET line 39 when a signal is received from the zero line 25.
  • the increments received from the increment line 26 are then counted in the counter.
  • the determined number is given as an address to the memory 37 via the address line 40.
  • This memory receives signals via the encoder line 30 when the encoder 17 receives a position which is to be glued later and which is read from a reading format 28, as shown in FIG. 2.
  • the memory 37 is also instructed by the control logic 34 via the read / write line 41 to store the values obtained from the encoder 17 in the addresses obtained via the address line 40.
  • the reading format 28 has been read through completely, the memory 37 stores exactly at which points the gluing is to take place later and where it is not.
  • the command “glueing” is then set on the control panel 35.
  • the memory 37 receives from the control logic 34 via the read / write line 41 the write, ie. H. the output signal.
  • the increment line 26 and the counter and the address line 40 are again counted up like addresses in the memory 37.
  • the logical value “0” is located in addresses for which the transmitter 17 did not determine a signal during the read-in process, while the logical value “1” is located in addresses for which a signal was received. These values are given via the output line 42 to the output stage 38, which then controls the glue nozzle 13 via the control line 32.
  • the computer 16 additionally has a read-only memory 43 and an adder 44.
  • the address line 40 between the counter I and the memory 37 is no longer present. Instead, there is an address line 40.1 between the adder 44 and the memory 37.
  • the adder 44 is connected to the control logic 34 via an enable line 45.1 and to the counter I via a count line 46.
  • the read-only memory 43 is connected to the control logic 34 via an enable line 45.2 and to the adder via a fixed-value line 47.
  • this circuit functions essentially as described above. The only difference is that the count value of the counter I is not sent directly from the adder 44 to the memory 37 via the address line 40, which is no longer present, but rather via the count line 46 and the address line 40.1.
  • the adder 44 receives the signal via the enable line 45.1 not to carry out any additions, but rather to pass the count value directly from the counter I to the memory 37.
  • the read-only memory 43 and the adder 44 are released.
  • An incremental number is permanently stored in the read-only memory 43 and corresponds to a path covered by a format during a mean switch-on and switch-off dead time of a glue nozzle.
  • This fixed value is added in the adder 44 to the count value from the counter I, so that a value with dead time compensation is given to the memory 37, which is higher than the count value from the counter I.
  • the glue nozzle 13 is already activated before a via the glue nozzle drawn format with a point to be glued that has reached the glue nozzle.
  • the position of the format to be glued is exactly above the nozzle if it actually glues after the dead time has elapsed or no longer glues after it is switched off after a delay.
  • the address values generally specified above are illustrated in examples in FIGS. 5 and 6.
  • the starting point is the aluminum strip 29.1 in FIG. 2. This is attached to the reading format 28 in such a way that the first quarter of the format cannot be glued, the middle half is glued and the last quarter remains free of glue. With a total of 100 increments across the entire length of the format, gluing should therefore take place from the 25th to the 75th increment.
  • the logical value “0” is thus stored in addresses 0 to 24 in memory 37, the logical value “1” in addresses 25 to 75 and the logical value “0” in addresses 76 to 100. This is shown in FIG. 5. If a dead time compensation is now carried out, then for each increment incremented by the counter I, z. B. added five increments.
  • the address «25» is already present at the memory 37. However, the logical value «1 is stored for these. The glue nozzle 13 is thus already activated when the counter I has only counted 20 increments. However, the counter I z. B. 71 increments counted, the address «76 is already given to the memory 37 via the adder 44. However, the logical value “0” is stored in the memory 37 for this address. Thus, the glue nozzle 13 is no longer activated from the increment value «71».
  • a dead time gate and the associated counter work together as follows.
  • a dead time entered via the control panel 35 is specified by the dead time gate while the associated counter is counting.
  • a speed-dependent increment number is thus determined. If the machine is running slowly, the counting disk 18 delivers only a few increments during the dead time, while it delivers many increments during a fast run. 4 and replacing the read-only memory 43 with a dead time gate and an associated counter, it is now possible not only to add a fixed increment number to the increment number of the counter I to compensate for dead times, but it is also possible to to make a speed-dependent compensation.
  • the circuit according to FIG. 7 is not only able to take into account different speeds, but also takes into account different dead times for switching the glue nozzles 13 on and off.
  • the on-dead time of a glue nozzle 13 is z. B. about 11 ms; while the off-dead time is about 23 ms, about double. It is assumed that counter E counts five increments during the on-dead time communicated to it by on-dead time gate 48, while counter A counts ten increments during off-dead time communicated to it by off-dead time gate. These increments are now alternately passed to the adder 44 via the multiplexer 50.
  • increment values each arrive at the memory 37, namely an increment value determined by the counter I, which forms the starting address, a second increment value, which consists of the starting address in addition to the value determined by the counter E, and a third value, which consists of the starting address and the value determined by counter A.
  • a certain logical value is stored in the memory 37 for each of these three different addresses.
  • the stored values for such different addresses are shown in FIG. 9.
  • the counter I delivers z. B. the address «10», then the address «15 is obtained by adding the value from the counter E.
  • the logical value “0” is stored in the memory 37 for this address. If the increment value «10 of counter A is added to the address of counter I, address « 20 »is obtained. The logical value “0” is stored in the memory 37 for these. The power amplifier is then not activated. If the counter I then specifies the address "15", the two other address values are "20 and" 25 ".
  • the logical value “0” is stored in the memory 37 for the first of these two values and the logical value “1” for the second. Because one of the values like before «0, the output stage is not yet controlled.
  • the glue nozzle 13 is to be switched on five increments before the address number determined by the counter I without reading dead time during reading. If the formats then continue to move and counter I reaches the address level "65”, the other two addresses are "70” and "75”. The logical value “1” is stored in the memory for both address values. The output stage therefore controls the glue nozzle 13 as before. If counter 1 then reaches address «66», the other two address values are «71» and «76».
  • the logical value “1” or “0” is stored in the memory 37 for these address values. Since both logical values are no longer “1”, the output stage no longer controls the glue nozzle 13. Thus, the glue nozzle is no longer activated ten increments before the number of increments that counter I determined when reading in for the glue nozzle 13 no longer being activated. However, this effect is exactly desired, since according to the example the dead time of 23 ms for the switch-off process corresponds to an increment number «10 to be kept. This sequence is also shown again in FIG. 8. For the output addresses. "0 to” 19 gives the output stage the logical value "0, for the addresses" 20 to "65 the logical value” 1 and for the address values "66 to” 100 the logical value "0" again.
  • This comparison circuit 51 is connected to the output stage 38 via an output line 42 and controls it only if the address values, which are determined from the sum of the counters I and E or I and A, both form an address content of the logical value.
  • two dead time gates and two counters interacting with them were used for dead time compensation for the switching on and for switching off.
  • only one gate and one counter can be used, which are then to be operated in multiplex mode.
  • a logic other than that described can also be used for the circuit, which specifies when to glue depending on the provisions for switch-on and switch-off dead times, and compares the memory contents for different addresses to determine whether both memory contents have the logical value « 1 »or not.
  • the route described is particularly advantageous.
  • the displacement sensor should consist of a toothed disk 18 and light sources 23 and light-sensitive elements 24.
  • path sensors e.g. B. inductive or mechanical digital displacement sensors can be used.
  • analog displacement sensors the values of which must then be digitized by means of a converter before being entered into the computer 16.
  • the displacement sensor should be connected to the transverse perforation cylinder 14 in a rotationally fixed manner.
  • the path encoder can be connected to any shaft of the glue machine, which gives a fixed relationship between the rotation of the shaft and the distance traveled by a format.
  • the reading format 28 should be provided with aluminum strips 29 at the format positions to be glued later. Strips for different donors should be arranged side by side and the donors should be arranged in the paper travel direction 20 at the same height as the glue nozzles 13 (i.e. opposite the glue nozzles). All of these conditions can also be varied. So z. B. strips of different phosphors are superimposed, which are then viewed by light-sensitive elements with different sensitivity during the passage at the respective measurement point. If it is possible to mount the transducers at the same height as the glue nozzles, path differences in this regard must be taken into account by means of corresponding increment numbers in the computer. In any case, it is advantageous to use sensors that are relatively dead-time for recording measured values.
  • control devices according to the prior art have displacement sensors which determine the path of a format and at the same time indicate whether gluing is to be carried out or not
  • a displacement sensor which only outputs increments directly or after an analog / digital conversion
  • the circuit between the displacement sensor and glue nozzles only serves to forward the signals received by the displacement sensor.
  • the circuit designed as a computer is used to first store signals received from additional measuring transducers via strips to be glued and then to pass the stored values on to the output stages for the glue nozzles whenever certain increment numbers occur.
