Definitions

  • the invention relates to a tear-off device for paper webs or single sheets in office machines, in particular in matrix printers, which have a cylindrical platen with friction rollers lying on top, a paper guide assigned to them and a tear-off rail.
  • printers especially computer controlled printers
  • printers create the complete documents.
  • the printer only supplements pre-printed forms with free lines and fixed (i.e. unchangeable) texts with variable texts.
  • airline tickets consist of pre-printed forms on which the name of the passenger and the flight data are printed.
  • paper and many types of forms are offered as endless sheets.
  • Each element of these sheets - each individual form or each individual blank sheet - is separated from the adjacent elements by means of perforations, which make it possible to separate the printed documents from the continuous sheet by tearing off the printed document as soon as the printed document has reached the printer leaves.
  • the sheets are usually folded up at the perforations.
  • the endless sheets are moved through the printer using tractor devices.
  • the tractor devices are provided with drive belts or transport wheels with pins which engage in perforations which lie on tear-off strips which run along the edges of the endless sheets.
  • the feeders referred to as "tractors" have a number of advantages. First of all, these prevent the endless sheets from slipping when they pass through the printer. They also ensure the correct alignment of continuous form sets when these marginal perforations pass through every punch sheet of the form sets.
  • the tracing devices of most printers are located behind the printing mechanism, ie at a location downstream of the printing roller. These tractor devices pull the endless sheets through the printer.
  • the printed documents are moved to a point behind the tractor device before they are torn off along the perforations provided for separation. This usually leaves a blank space between the individual documents, since the tractor devices are usually a few centimeters behind the platen. This loss of space can still be defended if long documents are printed on cheap blank paper or if pre-printed information is located near the top of a document or if you want or need a larger blank area at the top of a document.
  • the tear-off mechanisms to date have proven to be not entirely satisfactory for several reasons. In some cases, they are at an unfavorable distance behind the print head. In other cases the tear-off edge works satisfactorily for a certain paper weight of the continuous sheets, but problems occur with other paper weights. Further difficulties arise with multi-layer continuous paper or with continuous form separating sets.
  • the present invention has for its object to provide a tear-off device for paper webs or single sheets in office machines, in particular in matrix printers, which has a narrow construction, is as close as possible to the printhead and is suitable, the difference the best paper qualities (paper weights or paper thicknesses) as well as multiple forms.
  • the stated object is achieved in the tear-off device described in the introduction in that the tear-off rail in the paper transport direction is successively assigned to the tear-off edge, the friction rollers are directly assigned, and in that the friction rollers are arranged on a common roller axis which can be adjusted against the platen roller under adjustable spring force.
  • This invention can be applied to printers that have a friction feed only by means of the platen roller and the friction rollers, i.e. work without tractor devices. Since the pressure of the feed rolls can be regulated, papers and multiple form sets of different thicknesses (different paper weights) can be printed and separated into individual forms.
  • the size of the print can be regulated at least for the friction rollers, so that it corresponds to the requirements depending on the weight and size of the paper or form to be printed.
  • the tear-off device is very compact, i.e. can be built very narrow and can therefore be arranged in the immediate vicinity of the print head without taking up too much space.
  • An improvement of the invention is that the tear-off rail and the roller axis can be adjusted with the friction rollers as a unit against the platen.
  • a tear-off device equipped with these features is able not only to regulate the pressure force of the tear-off rail and the pressure force of the friction rollers, but also to choose the same size.
  • a particularly compact, ie space-saving design of the tear-off device is achieved, however, by the roller axis with the Friction rollers are arranged inside a tear-off rail, which is formed with an approximately trapezoidal cross-section from a rail side part, a rail base part and a further rail side part. It is hardly possible to move the friction rollers closer to the tear-off rail. This solution should therefore have reached the highest technical standard in terms of compactness, ie the narrow construction of the tear-off device.
  • a further advantageous structural design of the tear-off device is achieved according to the invention in that the tear-off rail is fastened together with the roller axis to a left hinge bracket and to a right hinge bracket, the hinge brackets each having hooks in which the respective fastening arms engage with hooks and that the fastening arms are each guided to a coil spring device and acted upon by a coil spring.
  • a tear-off device has the additional advantages that the operator can pivot the entire device away from the platen roller, that during operation of the office machine the tear-off device tends to lean against the platen roller and the advantage that the entire tear-off device can be easily removed can.
  • Such a tear-off device could therefore also be retrofitted to known office machines.
  • hinge brackets are pivotably mounted on the side plates of the machine frame about a common axis.
  • the helical spring device for this purpose consists of a spring housing receiving the helical spring, and the spring housing is resiliently supported on a plate of the machine frame by means of a spring arm.
  • pivoting movements can also be permitted by providing an extension on the spring housing and by guiding a rod in the extension, the extension consisting of a pair of strips which inhibit the rod and the rod being fastened in the side plates.
  • a pivotable locking lever is attached to the roller axis in the area of one of the hinge brackets and that. the respective hinge bracket a piston supported by a helical spring is provided in a housing which engages in teeth of the locking lever.
  • the pivoting range of the locking lever is limited in that a stop is provided on the locking lever, which abuts the piston at a maximum pivoting position, the coil spring of which is in the compressed position.
  • the friction rollers are provided with a toothed outer surface on their cylindrical circumference.
  • Fig. 1 shows the preferred embodiment of the invention mounted on a printer.
  • the elements of the printer shown in Fig. 1 comprise a pair of vertical side plates 11 and 13 which are part of the office machine housing.
  • the side plates 11 and 13 are located in parallel planes and carry a platen roller 15, the shaft 17 of which is mounted in bearings 19 which are provided in the side plates 11 and 13.
  • Below the platen 15 is one Paper guide 21 which receives and guides the paper below the platen roller 15.
  • a paper support 23 runs across the upper, rear quadrant or in the output region of the printing roller 15.
  • a conventional roller knob 25 is attached to the end of the shaft 17 of the platen roller 15. In the area of the front, lower quadrant of the roller there is a rod 27 which extends between the side plates 11 and 13 and is held by these.
  • the tear-off mechanism includes a tear-off rail 31 and a coil spring device 33.
  • the tear-off rail 31 is shown particularly clearly in FIG. 2.
  • the tear-off mechanism comprises the following essential parts: right and left hinge brackets 41 and 43, a roller axis 45, a number of friction rollers 47, a number of roller guides 49, a tear-off edge 51, an axle support 53, a latching lever 55, a latching mechanism which consists of teeth 56 on the latch lever 55, a piston 57 and a coil spring 59.
  • the mechanism further consists of a spring cover 61, a curved washer 53, a flat washer 65 and a pair of pins.
  • the left and right hinge brackets 41 and 43 connect the remaining elements of the tear-off mechanism to the machine frame. More precisely, the left and right hinge brackets 41 and 43 include a vertically arranged, predominantly flat middle piece 71, which has a circular cutout 73 on the underside which runs parallel to the plane of the middle piece 71 and thus forms a front part 75 and a back part 77 .
  • the diameter of the lower circular cutout 73 is slightly larger than the diameter of the platen roller 15.
  • the back parts 77 of each of the hinge brackets 41 and 43 contain a hinge opening 79 which serves to hinge brackets 41 and 43 through pins with corresponding openings on the vertical side plates 11 and 13 of the machine frame to ver tie.

  • the flanges 83 extend from the sides of the center pieces 71 to the outside opposite the side plates 11, 13, to which they are fastened with pins.
  • the projections 85 are designed so that they fit into the ends of the tear-off rail 31, which are designed in the manner described below.
  • the friction rollers 47 are cylindrical rollers which have a toothed outer surface which is made from a suitable material, for example from suitable plastics. Although three rollers are shown in the drawings, a smaller or larger number of friction rollers 47 can be used, depending on the requirements.
  • the openings 89 in the friction rollers 47 are dimensioned such that the friction rollers 47 can be pushed onto the roller axis 45.
  • a roller guide 49 belongs to each of the friction rollers 47.
  • Each roller guide 49 is provided with a yoke fork 91 which is dimensioned such that a friction roller 47 can be placed between the side guides of the yoke fork 91.
  • the side guides of the yoke fork 91 are provided with openings 93, the size of which is also such that the roller guides 49 can be pushed onto the roller axis 45.
  • the roller guides 49 also include cantilevers 95, the size of which allows the operator to finger them to grasp so that the operator can move the roller guides 49 individually, whereby he can push the friction rollers 47 located between the yoke forks 91 back and forth along the roller axis 85.
  • the friction rollers 47 are laterally adjustable to transmit a uniform force to the paper located between the friction rollers 47 and the platen roller 15.
  • the tear-off rail 31 consists of a substantially trapezoidal rail which is mounted with the opening facing downwards, i.e. the rail side parts 97 and 101 of the tear-off rail 31 are directed downwards and not upwards.
  • the rail side parts 97 and 101 of the tear-off edge 51 are not essentially parallel to one another in a trapezoidal shape.
  • the front rail side part 97 when the tear-off rail 31 has been installed as described below, lies at a right angle to the rail base part 99 of the tear-off rail 31.

  • the angle is chosen so that the rear rail side part 101 runs along a diagonal to the platen roller 15 when the tear-off device is correctly mounted on a printer, as was shown in FIG. 4.
  • the roller guides 49 have a slot between the yoke forks 91 and the projection 95, which is arranged and shaped so that it can receive the front rail side part 97 of the tear-off rail 31.
  • the axle carrier 53 is provided with a hub 105 which has a flange 107 which extends outwards. This flange 107 has a hook 109 at one end.

  • the main part 123 with the teeth 56 is designed so that it is adjustable in the recess, which is formed by the center piece 71 of the hinge bracket 41 and the flange 83 of the left hinge bracket 43, when the opening 129 in the main part 123 with the Roller axis opening 81 is aligned in the front part 75 of the left hinge bracket 43.
  • a housing 131 (FIG. 3).
  • This housing 131 runs along a diagonal to the roller axis opening 81 in the front part 75, in which the roller axis 45 is accommodated.
  • the housing 131 is sized and shaped to have the coil spring 59 and the piston 57 can accommodate.
  • the cross-sectional shape of the recess in the housing 131 should be rectangular, as should the cross-sectional shape of the piston 57.
  • the piston 57 is provided with a tapered tip that is adapted to fit the spaces between the teeth 56 , which are formed on the circular surface of the main part 123 of the locking lever 55, strikes and reaches into it.

  • a slot 150 is made in the outward, lever-side surface of the main part 123, which runs along a diagonal to the opening 129 of the roller axis 45.
  • the outer end of the lever arm 121 is provided with a thumb lever 132.
  • the tear-off device shown in the figures comes about by mounting a friction roller 47 between the flanges of the yoke fork 91 of each roller guide 49 and pushing the resulting component onto the roller axis 45.
  • Slotted disks 141 are pushed onto suitable annular grooves 143, which are embedded on the roller axis 45.
  • the slotted disks 141 are arranged so that at least two rollers 47 always press on the record carrier 144 to be printed (for example one sheet or several sheets of paper or light cardboard) which is currently being printed.
  • the third friction roller 47 which does not always come into contact with the recording medium 144 to be printed, holds the roller axis 45 in a position parallel to the surface of the platen roller 15. This arrangement results in the application of a uniform pressure on the recording medium 144 to be printed. A constant pressure prevents the recording medium from slipping.
  • the right and left hinge brackets 41 and 43 are pushed onto the end of the roller axis 45 and the tear-off rail 31 is placed above the projections 85, which are on the inner surfaces of the right and left hinge brackets 41 and 43 lie so that the rail side part 97 of the trapezoidal rail, which forms the tear-off edge 51, comes to lie in the slots which are formed between the projections 95 and the yoke forks 91 of the roller guides 49.
  • a pair of screws 145 are first passed through the openings located at the ends of the front rail side portion 97 of the tear-off rail 31 and then screwed into the openings located on the front of the projections 85 located in the inner surfaces of the right and left hinge bracket 41 and 43 are formed.
  • a second pair of screws 147 are passed through openings in the flanges 103 which extend upward from the base of the trapezoidal tear-off rail 31 and are then screwed into the threaded openings of the center piece 71 of the right and left hinge brackets 41 and 43.
  • the axle carrier 53 is pushed onto the right end of the roller axle 45 and then brought into the depression which is formed by the middle piece 71 and the flange 83 of the right hinge bracket 41.
  • roller shaft 45 is then rotated about itself in such a way that an opening 149 lying on the circumference, which is embedded next to the adjacent end of the roller shaft 45, is aligned with the slot 115 in the hub 105 of the hinge bracket 43.
  • one of the pins 67 is slid into the slot 115 which is in the hub 105 of the axle beam 53 and the opening 159 in the adjacent end of the roller axle 45.
  • the locking lever 55 is mounted on the other end of the roller shaft 45 so that the teeth 56 come to rest in front of the housing 131.
  • the piston 57 and the coil spring 59 are mounted in the housing 131 and the spring cover 61 is attached to the right hinge bracket 43.
  • the curved washer 63 and the flat washer 65 are mounted on the roller shaft 45.
  • the roller shaft 45 is rotated so that a circumferentially opposite opening 151, which is embedded in the adjacent end of the roller shaft 45, is in line with the slot 150, which is located in the side of the main part 123 on which the lever arm lies .
  • the other pin 67 is inserted into the slot 150, on the main part 123 on the lever arm side and into the opening 151 in the abutting end of the roller axis 45.
  • the roller axis 45 is rotated by rotation of the locking lever 55, which is brought about by movement of the lever arm 121. It follows from this that the position of the hook 109 of the axle support 53, as well as the position 127 of the locking lever 55, is controlled by the respective position of the locking lever 55.
  • the latching mechanism naturally holds latching lever 55 in each of the various latching positions provided, which are achieved by piston 57 engaging a tooth space between teeth 56.
  • the coil spring devices 33 each consist of a spring housing 161 in which a coil spring 163 is located.
  • a fastening arm 165 runs along the rear wall of the spring housing 161.
  • the lower end of this fastening arm 165 has a transverse section 169 which extends below the lower end of the coil spring 163 and presses the other end of the coil spring 163 against the upper part of the spring housing 161.
  • the coil spring 163 exerts downward pressure on the mounting arm 165.
  • the other end of the mounting arm 165 extends upward from the spring housing 161 away and ends in a hook 167.
  • the hook 167 engages the hook 109 or the hook 127 of the associated axle support 53 or the locking lever 55.
  • the spring housings 161 also have clamp-shaped extensions 170 which extend to the rod 27 and can clamp it .
  • the rod 27 extends between the side plates 11 and 13 of the machine frame, as described for FIG. 1 and above.
  • a spring arm 172 extends outward from each spring housing 161 of the coil spring devices 33. The outer ends of the spring arms 172 meet a plate 174 which is part of the machine frame or an anchoring device (not shown) attached to the machine frame.
  • the spring arms 172 develop a force which causes the associated spring housings 161 and the fastening arms 165 to pivot in the direction of the platen roller 15.
  • the fastening arms 165 are pulled upwards when the lever arm 121 of the latching lever 55 is rotated counterclockwise, as shown in FIG. 3.
  • This additional pressure is transmitted through the right and left hinge brackets 41 and 43 and via the roller axis 45 to the friction rollers 47 and the tear-off rail 31.
  • the lever position of the locking lever 55 controls the force exerted by the friction rollers 47 and from the tear-off edge 51 on the recording medium 144 which lies between these elements and the friction roller 15.
  • the write head (not shown) moves slightly below the tear-off edge 51 across the paper.
  • the write head could be a matrix print head, for example.
  • the lever arm 121 If the lever arm 121 is rotated clockwise (as shown in FIG. 3) until it has reached its outermost position, the stop 128 engages on the underside of the left hinge bracket 43. In this position, the axle carrier 53 and the locking lever 55 are released from the hooks at the ends of the fastening arms 165. This separation takes place because the subsequent movement of the fastening arms 165, which was caused by the spring arms 172, is ended when the spring housings 161 hit the paper guide 21 of the printer (FIG. 1). As a result, the tear-off device is released. When the tear-off device is released, it can be pivoted away so that the recording medium 144 can be inserted into the printer.
  • this invention is ideally suited for use in printers designed to print on continuous blank sheets or forms, with feeding to the printer platen either through upstream tractor devices (not shown). or the paper to be printed is drawn in solely by the friction between the platen roller 15 and the friction rollers 47.
  • upstream tractor devices work most successfully when the peripheral speed of the platen roller is slightly above the retraction speed of the tractors.
  • This speed difference excludes paper jams between the tractor devices and the platen and can be easily achieved by slightly oversizing the platen in relation to the drive speed.
  • the main disadvantage of this speed difference is the necessity that the recording medium to be printed, for example the paper, has to slide on the roller. While it is relatively easy to slip a single sheet in the desired manner, difficulties can arise if the recording medium is multi-ply paper. Problems then arise because the different layers can move against each other, which leads to unevenness, especially if the layers are not connected in any way, such as by an adhesive which has been applied along the area of a perforated tear-off edge, which is located along the edges of the continuous paper, the continuous sheets or the continuous forms. As shown in Figure 5, this invention also provides a mechanism to address this problem.
  • FIG. 5 shows a pair of strips 171 which have been attached to a platen roller 173.
  • the inside diameter of these strips 171 is dimensioned such that the strips 171 can "slide” on the platen roller 173.
  • a plurality of pins 175 are attached to these strips 171 and protrude outwards.
  • These pens lie on a ring encircling the platen roller 173 and, like the pens of conventional printer tractor devices, are dimensioned and arranged at similar distances from one another. They are dimensioned according to these pins to the perforations on the edge strips of continuous sheets of paper or Record endless forms.
  • each strip 171 is assigned to one of the friction rollers 47, which are mounted on the roller axis 45 of the tear-off device.
  • Friction supply tear-off devices constructed in accordance with the present invention have worked very well after testing if the recording medium was multilayer paper, the layers of which were bonded to one another either along the edges of the paper or in other areas of the sheets (eg glued). in order to enable a very specific separation of the arches as desired by the user (e.g. one arch plus three arches plus two arches).
