Definitions

  • the invention relates to a method and a device for producing continuous forms with a transverse perforation and guide holes within a tractor perforation.
  • Continuous forms are produced by unwinding a paper web from a roll and feeding it to a processing machine, which may print the paper web with a form print, but in any case with perforations for the tractor in the computer printer, as well as a longitudinal and transverse perforation, which as Separation and fold perforation serve, provides.
  • the printed or unprinted continuous forms which are also known as ruler paper, are deposited as a continuous paper web at the machine outlet either in a zigzag fold, using the cross perforation as fold perforation, or wound up on a roll again.
  • the paper web is guided over a swiveling roller with a wrap angle of more than 90 °. Adjusting this so-called setting roller allows the deviation from the squareness to be corrected.
  • the vertical misalignment of the guide holes within the tractor perforation and the format, as well as the tendency to tilt in the running direction are influenced, which are due to deviations in the spacing of the transverse perforation.
  • deviations from the nominal size are compensated for by appropriate pulling devices which stretch the paper web more or less in the longitudinal direction.
  • DE-A1-37 44 107 discloses a device for producing transverse lines on material webs, in which the feed conveyor unit can be adjusted by means of an angle adjustment by means of an alignment device.
  • the material web can be passed through the cross-line unit even with longitudinal edges of different lengths, so that the cross-lines are always manufactured at the correct angle.
  • only material webs can be used with this known device that already have an edge perforation.
  • the adjustment must be made by hand at intervals.
  • the quality assurance procedure that has been practiced to date has considerable shortcomings. Since random samples are taken, the absence of errors can only be guaranteed with a certain probability. The error rate is based on the probability of information being within a certain spread. Some tests destroy the material, so that a test density of 100% cannot be achieved. For a number of applications, the paper is rolled up again at the outlet of the processing machine, so that sampling of these products is only possible at the beginning and end of the roll, since there should be no glue points in the roll. Furthermore, the machine tool is reset after an error message; the success of the new adjustment of the machine must be checked by taking a new sample.
  • the object of the invention is to create a method and a device for the production of continuous forms, in which a deviation from the requirements for the continuous forms with regard to the tractor perforation and the transverse perforation is reliably excluded for each production volume.
  • a paper web 2 is unwound from a roll 1 and fed to a processing machine 3 which introduces both the tractor perforation and the longitudinal and transverse perforations into the paper web.
  • the processing machine 3 can also apply a form print to the paper web. In the example shown in Fig. 1, however, the paper web is not printed.
  • the processed paper is placed on a stack 4 by alternately folding the paper web in a zigzag fold along the transverse perforation.
  • the stack 4 represents a production volume of the endless forms which, according to the invention, was continuously checked for compliance with the dimensional specifications with regard to the perpendicularity and nominal dimensions of the transverse perforation and the verticality and longitudinality of the guide holes within the tractor perforation.
  • Fig. 1 the position and dimensions of the tractor perforation and the transverse perforation are shown in an enlarged section of the continuous form web.
  • the distance l Q of the transverse perforations A from one another must be kept constant, since otherwise forms of different lengths are stacked on top of the stack 4, which leads to the stack tipping in the running direction, since the transverse perforation is usually introduced with the aid of a knife roller, the two or more rows of knives having.
  • the cross perforation is created with an angle (alpha) that of deviates from the desired value of 90 °, so that the perpendicularity of the transverse perforation in relation to the paper web is disturbed.
  • This deviation (alpha) of the transverse perforation A from the perpendicularity leads to a rotation of the stack 4 if a transverse perforation deviating from the perpendicularity occurs alternately with a transverse perforation created at right angles.
  • both knives are at an angle, ie if transverse perforations deviating from the perpendicularity occur successively, the stack 4 tilts transversely to the longitudinal direction of the paper web.
  • An inclined paper web 2 which deviates from an ideally rectangular orientation in terms of its feed into the processing machine 3, also leads to the deviation of the transverse perforation.
  • both the distance l B as the size of the longitudinal side of the guide holes B and the offset l V between guide holes B are of importance, which correspond to one another in the two lateral perforations.
  • the continuous forms produced according to the invention are characterized in that these characteristic quantities are continuously recorded and checked for each individual form of the stack 4.
  • the production volume of the stack 4 therefore certainly has the desired qualities in each section of the continuous form web, since according to the invention the continuous forms are continuously dimensionally controlled.
  • the continuously dimensionally controlled endless forms according to the invention are characterized in that compliance with the specification and the associated requirements for the endless forms with regard to further processing in IT printers with certainty over the entire production volume. So far, only a statistically substantiated statement has been made about the fulfillment of the requirements placed on the continuous forms, so that considerable advantages are achieved by the continuously dimensioned, continuously controlled forms according to the invention, since the qualities and properties of the continuously dimensioned, continuous forms are certainly met.
  • the measuring device consists of five optical transmitter / receiver units 5a to 5e, which include, for example, an optical laser as a transmitter and a photodiode as a receiver.
  • the optical transmitter / receiver units 5a to 5e can be advantageous be supplemented by five optical devices which bring the raw beam of the transmitter part, ie the optical laser used, into a form suitable for the measuring task.
  • the use of only one transmitter can also be used together with a suitable optical device for dividing and distributing the light emanating from the transmitter part.
  • a He-Ne laser is a suitable laser, whereas in the other case semiconductor lasers can be used advantageously.
  • the five transmitter / receiver units 5a to 5e are arranged on the endless form web as in FIG. 2 and are used in the groups described in more detail below for the continuous dimensional control of the endless forms.
  • the optical transmitter / receiver units 5a to 5e are each arranged so that the perforation or perforation to be detected moves through the detection area of the transmitter / receiver unit and triggers a signal shown in FIG. 3.
  • the upper illustration in FIG. 3 shows the case in which the paper web interrupts the beam path between the transmitter part L and the receiver part D of the transmitter / receiver unit. Even when the paper web is moved, the output signal of the transmitter / receiver unit remains at a constant value, as is shown schematically in the upper diagram in FIG. 3. If perforation or perforation due to the movement of the endless forms enters the beam path of the transmitter / receiver unit, as shown in the lower illustration in FIG. 3, the transmitter / receiver unit emits an output signal, the course of which over time the lower diagram of Fig. 3 is shown schematically.
  • the appropriate arrangement and alignment of the transmitter / receiver units makes it possible to detect the transverse perforation and the guide holes in the tractor holes. With the five optical transmitter / receiver units shown in FIG. 2, complete recording and continuous dimensional control of the endless forms is possible.
  • the five transmitter / receiver units 5a to 5e are arranged individually in three groups 1 - 1, 2 - 2 and 3 - 3, which reflects an assignment of the transmitter / receiver units to one another with regard to the size of the endless forms to be recorded.
  • the group 1 - 1 is arranged so that its degree of connection runs perpendicular to an ideally running paper web or is aligned parallel to the axis of the rotating perforation unit. With the help of the two transmitter / receiver units 5a, 5b of the group 1 - 1 the transverse perforation (fold perforation) is detected. If the transverse perforation is perpendicular to the longitudinal direction of the paper web, the detection signals of the two transmitter / receiver units of this group occur simultaneously. If the transverse perforation deviates from the right angle to the paper web, there is a deviation corresponding to the illustration shown in FIG. 4.
  • FIG. 4 schematically shows a paper web with oblique transverse perforation and the two transmitter / receiver units 5a, 5b of the group 1 - 1.
  • the two diagrams show the time course of the detection signals which are emitted by the transmitter / receiver units on one or on the other side of the paper web. As can be seen from the diagrams in FIG. 4, this is when the continuous form web is moved from left to right Detection signal of the lower transmitter / receiver unit 5a earlier than that of the upper transmitter / receiver unit 5b.
  • the time delay (delta) t can be determined and a path difference can be determined from this, which corresponds to the inclination of the transverse perforation.
  • the group 3 - 3 consisting of two transmitter / receiver units 5b, 5c is provided, with the aid of which the speed of the moving continuous form web is detected.
  • the transmitter / receiver units 5b, 5c of the group 3 - 3 are arranged at a precisely defined distance R from one another, which is advantageously set with a measuring microscope, for detecting the transverse perforation on one side of the paper web so that a connecting straight line between them runs parallel to an ideally running paper web or perpendicular to the axis of the rotating perforation unit.
  • the speed of the continuous form web can be determined from the time T required for this and the known distance R between the two transmitter / receiver units 5b, 5c. With this arrangement, measuring accuracies of up to 1/100 mm at a speed of the continuous form web of 10 m / sec. possible.
  • the transmitter / receiver unit 5b from group 3 - 3 also belongs to group 1 - 1 without this measure being absolutely necessary. However, this leads to the fact that one transmitter / receiver unit has to be provided less than with three separate groups. However, the web speed determination with the help of the group 3 - 3 can also be carried out with the help of two separately provided transmitter / receiver units the transmitter / receiver units 5a, 5b of the group 1 - 1 are independent.
  • a path difference can be determined which corresponds to the inclination of the transverse perforation and which is determined with the aid of the transmitter / receiver units of group 1 - 1, the deviation of the transverse perforation from the perpendicularity can be checked continuously.
  • About a production volume i.e. A certain number of endless forms produced can therefore be used to make a statement as to whether all the transverse perforations produced in the production volume meet the specified rectangularity requirements.
  • the continuous dimensional control of the transverse perforation thus creates endless forms which have an unprecedented level of quality, since a reliable statement about the perpendicularity of the transverse perforation is possible.
  • the group 2 - 2 which consists of two transmitter / receiver units 5d, 5e, which are independent of the other groups, serves to record the vertical distance l V and the hole distance l B of the guide holes in the tractor holes.
  • Transmitter / receiver units are arranged on the paper web so that the connecting line between the two transmitter / receiver units runs perpendicular to an ideally running paper web or parallel to the axis of the rotating perforation unit and the transmitter parts and receiver parts refer to the tractor perforation are aligned.
  • the detection of a deviation or its size is carried out in a similar manner to the inclination of the perforation, so that essentially the same conditions apply that are shown in FIG. 2 in connection with the checking of the perpendicularity of the transverse perforation.
  • guide holes within the tractor perforation can cause a time delay between the detection signals of the transmitter / receiver units 5d, 5e of the group 2 - 2, which can be detected and converted into a path difference.
  • the group gal - betician can also be used to determine the distance l Q of the transverse perforations (fold perforations).
  • the distance l Q which is responsible for the longitudinal tilting in the continuous form stack described at the outset is determined by first recording the time which two successive transverse perforations require to be first from the transmitter / receiver unit 5c in the direction of movement of the continuous form web is reached to reach the transmitter / receiver unit 5b, which is subsequently reached. It is therefore the time that two consecutive cross perforations take on their way from one to the other transmitter / receiver unit of group 3 - 3. The time recorded in this way is compared with an expected value which corresponds to a quotient of the current web speed of the endless forms and the transverse perforation distance l Q to be produced.
  • the group 2 - Loch is also used to check the longitudinal side l B of the guide holes. This check is carried out according to a similar principle as the determination of the distance l Q between two successive transverse perforations, so that a description of this process can be dispensed with.
  • the entire continuous form web can be checked for the geometric dimensions mentioned in connection with FIG. 1.
  • Each sheet defined by the transverse perforations is thus continuously checked for compliance with the requirements regarding the hole spacing l B (longitudinal side) and the verticality l V of the guide holes B as well as the perpendicularity (alpha) and the spacing l Q of the transverse perforation A.
  • the measuring arrangement it is thus possible to continuously produce dimensionally controlled endless forms according to the invention.
  • This production takes place according to the invention by a method with the following steps.
  • the web speed V of the continuous form web is determined by determining the time it takes for a transverse perforation and / or a guide hole within the tractor perforation to get from a first transmitter / receiver unit to a second transmitter / receiver unit, which is arranged at a predetermined distance R from the first.
  • this step is only necessary if the web speed V is not otherwise provided.
  • the second transmitter / receiver unit is arranged on the opposite side of the continuous form web such that a degree of connection between the two units perpendicular to The longitudinal direction of the continuous form web runs, the occurrence of detection signals, which are caused by the transverse perforation, is detected and, based on the time interval between the two detection signals and the web speed V, the inclination of the transverse perforation checked.
  • the distance l Q of the transverse perforations from one another is determined with the aid of the first and second transmitter / receiver unit, by recording the time it takes for two successive cross perforations to pass from the first of the transmitter / receiver units to that second to arrive, and by comparing the time recorded in this way with an expected value which corresponds to a quotient of the current web speed V of the continuous form web and the transverse perforation distance l Q to be produced.
  • the fourth transmitter / receiver unit is arranged on the opposite side of the continuous form web in such a way that a connecting straight line between the two units is perpendicular to Longitudinal direction of the continuous paper web runs, the occurrence of the detection signals caused by the guide holes is detected and, based on the time interval between the two detection signals and the web speed V, the vertical distance l V between the guide holes within the tractor holes is checked.
  • a fourth step the longitudinal and lateral alignment of the guide holes within the tractor perforation is checked with the help of the fourth and fifth transmitter / receiver unit by detecting the time between the detection of a guide hole by the fourth and fifth transmitter / receiver unit and the subsequent guide hole that passes through the movement of the continuous form web in the detection area of the fourth or fifth transmitter / receiver unit is moved.
  • a control circuit is shown schematically, which allows a regulation within the processing machine for introducing the tractor perforation and the transverse perforation with the help of the sizes of the continuous form web 2 detected by the five transmitter / receiver units 5a to 5e.
  • continuous dimensional control is possible.
