Definitions

  • the invention relates to a device for transporting individual forms or form sets from an input shaft to a printing point and back with drive means for the forms in front of and behind the printing point, with pressing means which can be pivoted into and out of the operative position and with which the forms are pressed against the drive means , and with alignment tools for the forms before they are moved in.
  • a wide variety of transport devices are known for printing individual forms or sets of forms, which advance the form relative to a printing point, transport it further during printing and, after printing, push it out again in the reverse direction.
  • the forms are driven both in front of and behind the printing point by drive and pressure rollers in order to ensure that the form is in any case kept taut at the printing point.
  • the drive and pressure means act simultaneously as a clamping device for the forms.
  • alignment means are required that align the forms on two mutually perpendicular edges so that the forms are clamped in the correct position and released for feed.
  • the task in particular is to be able to print the forms in such a way that the head and foot zone are kept as small as possible.
  • the print head and the transport device acting as a clamping device for the forms must be such that the printing can take place in the immediate vicinity of the upper and lower edges without the form being displaced.
  • the forms are driven in both directions, So be printed in the forward and reverse directions and also in both directions of movement, then it must be ensured that when using form sets there is no possible displacement of the upper and lower forms to each other, as is often the case with typewriters, for example.
  • the forms run between the transport and pressing means that are in contact with one another, which may already result in a slight shift in the top and bottom sheets of the form sets. This effect occurs especially when you drive backwards and when the form sets are diverted over a larger angle on their way. Then there may be significant shifts between the top and bottom sheets of the form set. These shifts are still portable on typewriters because most of the lower copies are for internal purposes only.
  • a non-shifted print image is an indispensable requirement when printing the forms on the one hand in the forward direction and on the other hand in the reverse direction. It is also not insignificant to point out that the device according to the invention should be such that it processes thinner and thicker individual forms as well as sets of forms with several layers equally well.
  • the front and rear drive and pressure means are only ever alternately effective and the forms are therefore only ever held by a number of the drive and pressure means, the printing can take place without difficulty up to the very bottom and top of the form.
  • the front and rear drive means are driven by a transport motor, which is preferably a stepper motor and therefore has no phase-out and start-up phase, while the front and rear pressing means and the alignment means are operated by a control motor so that the Transport and control motor can be switched on and off alternately. Due to the separate drive for bringing the pressure means and the alignment means on the one hand and the transport means on the other hand, a flying change between the front and rear pressure rollers is not necessary, rather the transport is stopped first and then the corresponding pressure means in and brought out of action, which is possible without a noticeable time delay.
  • a transport motor which is preferably a stepper motor and therefore has no phase-out and start-up phase
  • the front and rear pressing means and the alignment means are operated by a control motor so that the Transport and control motor can be switched on and off alternately. Due to the separate drive for bringing the pressure means and the alignment means on the one hand and the transport means on the other hand, a flying change between the front and rear pressure rollers is not necessary, rather the transport is
  • control motor is in drive connection with a number of cams, which in turn now bring the pressing means and the aligning means into and out of action in a staggered manner.
  • cam disk controls has the advantage over the individual control of the pressing means and alignment means via electronic and electromechanical means that fixed programming is provided, so that additional programming effort is not required for controlling these units.
  • the pressing means are activated so effectively that the form or the form sets are essentially always pulled away from the printing document.
  • FIG. 2A, 2B placed side by side result in a side view of the control elements and the control motor, different line shapes being used for the various control linkages to clarify the legibility.
  • the control linkage for the front pressure rollers is shown in full lines
  • the control linkage for the rear pressure rollers with dash-dotted lines and the control for the alignment means in dashed lines.
  • FIG. 3A, 3B and 4A, 4B which only show other functional positions.
  • a transport motor in the form of a stepping motor acts on a shaft 3 via a belt 1 and a belt wheel 2.
  • the An drive movement of the transport motor via a pulley 6 transmitted to a shaft 7.
  • the shafts 3 and 7 are thus driven by the transport motor in both directions of rotation, that is to say in the direction of intake and ejection.
  • the shafts 3 and 7 are provided as drive means with rubber-coated rear drive rollers 8 and 9, which act on the forms 11 or form sets to be transported from below.
  • the drive rollers 8 and 9 penetrate through recesses 14 in lower cover plates 13, 13 '.
  • Similar drive rollers 15 are attached to the shaft 7 as front drive means.
  • the front drive means 15 are covered by the cover plate 13 and only extend beyond this cover plate with a fraction of their circumference.
  • the cover plate 13 forms, together with a guide part 17, an insertion shaft 18 through which the forms 11 or form sets can be inserted.
  • Each drive roller 8, 9 and 15 is assigned a pivotable pressure roller 19, 2 0 , 21, which pass through upper cover, guide or holding parts 16, 16 '.
  • the printing pad 60 can be seen between the guide parts 16, 16 'and the printing head 61 in a broken line.
  • the pressure rollers 2 0, 21, the front pressing means which are each rotatably mounted on an axis 22 and are supported in two retaining arms 23 and 24th
  • the holding arms are supported by a common axis 25, the axis 25 being provided with a projection 26 which enters into a cutout 28 in the holding arms, so that the holding arms 23 and 24 are pivotably mounted on the axis 25 by a small amount.
  • a spring 27 influences the holding arms and thus the pressure rollers 2o and 21 in the counterclockwise direction.
  • the pressure rollers 2 0 , 21 remain raised.
  • the holding arms 23, 24 are still supported and guided in the holding part 16.
  • a lever 3o (on the left in FIG.
  • the situation is similar with the control of the pressure roller 19 and the corresponding further pressure rollers, which represent the rear pressure means. These are mounted on an axis 40.
  • the axis 40 is controlled by a lever 41 which, by means of a roller 42, senses a further cam plate 43, which is also driven by the motor 38 via the control shaft 44.
  • a comparison between the FIG. 2A and 4A shows that here the pressure roller 19 has been pressed into the pressure position relative to the drive roller 9.
  • the pressure rollers 19 are analogous to the pressure rollers 2 0, 21 and mounted movably on the axis 4o to ein.geringes measure.
  • the lever 59 is pivotable about the point 62 and scans a further small cam 64 with a roller 63, which is also fastened on the control shaft 44. With an extended arm 59 ', the lever 59 still acts on a microswitch 65.
  • a comparison between the position shown in FIG. 2A and B and 3A, 3B shows that the alignment means 5o are in the operative position for the form 11 before the start of the drawing-in process, but are pivoted by the curve 64 and then their ineffective position according to FIG. Take 3B.
  • a pivotable switching arm 67 which is actuated by the form 11 when it is inserted.
  • Another switching arm 68 (FIG. 1) is arranged so that it is pivoted through the left side edge of the form 11 when the form 11 is correctly inserted. If both switching arms 67 and 68 are actuated together, the pull-in process is released by this AND function.
  • the front drive means 15 and pressing means 2 0, 21, the pressure pad 6o and the rear drive means 8, 9, and pressing means 19 lie in a plane. From this it follows that occurs between the contact points between 2 0, 21 and 15, the pressure pad 6o and the contact points 19-8, 9 no deflection of the forms. Furthermore, it follows from the arrangement of all these points in one plane that a relatively flat construction of the entire arrangement is possible, which also makes it possible to set up such a form transport device on a table, because the pane and the ejection of the form are only slightly above the table plate can be made, so that this also results in a user-friendly arrangement.
  • the control motor 38 continues to run and the cam disk 64 pivots the alignment means 50 from the position shown in FIG. 2B into the position according to FIG. 3B. This clears the way for the entry of forms 11.
  • the lever 59 has actuated the microswitch 65 and has thus reported that the drawing-in process can begin because the alignment means 50 have been pivoted away.
  • the transport motor is switched on and the control motor 38 is switched off via a further cam plate 45, a lever 46 and a further microswitch 47.
  • the transport motor starts to run and drives the two shafts 3 and 7 and thus the drive rollers 8, 9 and 15.
  • the transport motor displaces now the forms 11 by the interaction between the drive rollers 15 and the pressure rollers 2 0, 21, which is calculated as a certain, predetermined by a program way that it the form 11, regardless of whether it is on the printing substrate 6o is already printed or not, between the pressure rollers 19 and the drive rollers 8, 9.
  • the transport motor is stopped according to this specific path and the printing process is thus briefly interrupted.
  • the control motor 38 is switched on again.
  • the form can be transported further, whereby it is now no longer held between the front drive and pressure rollers 15, 2 0, 21, but only still between the rear drive and pressure rollers 8, 9 and 19.
  • the form can therefore be labeled on the printing pad 6o by means of the print head 61 all the way to its lower edge, since the front pressure and drive rollers are no longer required to hold the form .
  • the form 11 could be labeled from its top edge.
  • the return of the form begins from the position shown in FIG. 4A, 4B by reversing the drive direction of both the transport motor and the control motor, the control motor 38 driving the control shaft 44 against the direction of the arrow in FIG. 2A to 4A drives.
  • the drive and pressure rollers 9, 8, 19 have a driving effect on the form 11.
  • the transport motor is stopped again and the control motor 38 is switched on, with the cam discs 37 and 43 first bringing the front pressure rollers 2 0 , 21 into contact with the drive rollers 15 are and then the rear pressure rollers 19 are raised.
