Definitions

  • the invention relates to a drawing board with a plotter, i.e. a controllably movable drawing pen, the plotter being movable over the drawing board
  • drawings up to DIN A 0 in size can be drawn by hand using rulers, compasses and stencils that can be moved over the drawing board.
  • drawings created in this way can then be digitized and entered into a computer which has a special program, a so-called CAD program.
  • Drawings saved in the computer and revised or changed on a screen can be printed out with a plotter. Plotters with different formats are available for this. Depending on the size of the paper format of the drawing and thus the format of the plotter, the costs of a plotter vary.
  • a plotter for the DIN A 0 character format currently costs at least DM 40,000.00.
  • plotters that have only a drawing area of DIN A3, but that can be placed on a larger drawing sheet and can be moved there. These plotters have an input keyboard with which the drawing pen can be moved. These plotters are relatively inexpensive and they can also be operated with the appropriate user software using so-called micro- or personal computers, which are already available in many writing and drawing offices. Using these plotters, various individual drawings of the maximum format DIN A3 can be drawn on a larger sheet. The plotter is moved and aligned by hand on this larger drawing sheet. However, with this method of working it is not possible to draw a figure that is larger than the DIN A3 format to be processed by the plotter.
  • Such a known plotter is e.g. distributed by Rotringtechnik GmbH under the name “NC-plotscriber”.
  • NC-plotscriber There are various control units and a CAD system (screen drawing system). This system is also very expensive.
  • the invention has for its object to provide a generic drawing board with which drawings of the format DIN A 0 can be created cheaper.
  • the total area of the drawing board is divided into several fields that at least touch or even slightly overlap each other and to which the plotter can be firmly assigned.
  • An essential element of the invention is a plotter that can be set in different, precisely definable positions relative to a drawing board.
  • This plotter does not have its own surface for the paper, but is placed on a drawing sheet, which is much larger in area than the plotter.
  • the plotter must therefore have no floor in the area of its drawing area, i.e. it has a frame that is open at the bottom.
  • Such a plotter essentially consists of a rectangular frame in which a guide rail is arranged displaceably in the direction parallel to a pair of side edges, the longitudinal extension of which lies transversely to these side edges.
  • One or more drawing pen (s) is / are along this guide rail. movable and perpendicular to the plane of extension of the frame mounted and lowered.
  • a plotter with a frame that is open at the bottom is known as such (cf. "NC-plotscriber" from Rotringtechnik GmbH).
  • the plotter now used here must still show the means of permanent assignment to a certain and determinable field, i.e. the plotter, like the well-known plotter, must not be able to move freely over the drawing board.
  • These means allow the plotter to be aligned and had exactly in relation to the individual fields.
  • Such means can be pens fixed on the drawing board, which can engage in bores that are provided either directly on the plotter or on a component that is firmly connected to the plotter. But it can also be provided both on the drawing board, and on the plotter holes, which are brought to escape and through the pens or the like for locking the plotter against the drawing board. are slidable.
  • Such a plotter preferably also has a keypad via which control commands for the pen (s) can be entered.
  • a drawing board 1 which is known as such and can also have a drawing machine, not shown, which can be folded away or swung away, has here, at least on its upper longitudinal edge, a horizontally arranged row of pins 2 which are evenly spaced from one another and whose axes are perpendicular to Extend plane of the drawing board 1.
  • this drawing board 1 is provided for maximum sheet formats DIN A 0 (1,189 mm x 841 mm) and has a width of 1.5 m and a height of 1 m.
  • a drawing sheet 3 of the DIN A 0 format is arranged on this drawing board 1.
  • This drawing sheet 3 is now divided into three times three matrix fields 4, which is indicated here by dash-dotted field boundary lines 5.
  • the drawing board 1 is provided for drawing formats DIN A1 (841 mm x 594 mm) and is correspondingly smaller.
  • a drawing sheet DIN A 1 is correspondingly arranged on this drawing board, which is set in two matrix fields 4 twice, as in FIG. 1
  • This division into matrix fields 4 need not be made by lines on the drawing sheet 3, although such auxiliary lines facilitate the overview.
  • Each of these nine or four matrix fields 4 can be assigned one and the same plotter 6, so that nine or four different arrangements must be possible for this one plotter 6.
  • Each matrix field 4 is assigned a - here - two-digit field number 7, e.g. 11, 12, 13, 21, 22, 23, 31, 32 and 33 or 11, 12, 21 and 22, the first digit e.g. the "row” of the matrix indicates, while the second digit denotes the "column" of the matrix.
  • the fields 4 can also be numbered consecutively.
  • the plotter 6 can only process one matrix field in the size DIN A3.
  • a specific matrix field 4 e.g. in FIG. 1 for the matrix field 4 with the field number "23" and in FIG. 2 for the matrix field 4 with the field number "22”
  • the computer can internally manage an entire drawing sheet of the size DIN A 0 or DIN A 1 and it can also be drawn over the entire sheet format by successively shifting the plotter 6 if the computer is also given the field number 7 of the matrix field 4 to which the plotter 6 is assigned.
  • This is possible by means of a software program which, on the basis of the assignment of the specific matrix field 4, only selects the respective virtual image of the specific matrix field 4 from the virtual overall image of the memory of the computer.
  • the assignment of the plotter 6 to a specific matrix field 4 can be obtained on the basis of two similar designs of the drawing board, the embodiment according to FIG. 2 being possible only if the entire sheet is divided into a maximum of two fields 4, ie, for example, when in use of a DIN A3 plotter, only a drawing in DIN A1 format is to be created on a correspondingly smaller drawing board 1.
  • FIG. 1 shows the use of a DIN A 3 plotter 6 for the creation of a DIN A 0 drawing, a matrix with nine fields 4 being necessary.
  • the plotter 6 cannot - as in FIG. 2 - be fixed directly next to the drawing sheet, is on one Plotter 6 attached a plate 8, which should be as transparent as possible and here consists of a plexiglass
  • This plate 8 is here somewhat narrower than the greatest length of the plotter 6, while the length of the plate 8 - seen in the vertical in FIG. 1, that is in the direction of the shorter side edge of the matrix field 4 - is slightly larger than twice the length is the shorter side edge of the matrix field 4
  • This plate 8 now has three vertical rows of bores 9 that are evenly spaced from one another, i.e. for a DIN A 0 character format and a DIN A 3 plotter, the three rows also being evenly spaced from one another.
  • the distance between two rows of holes 9 is at most as long as the shorter side edge of a matrix field 4 is long. If the size of the matrix field 4 corresponds exactly to the format DIN A3, i.e. 420 mm x 297 mm, this is Distance eg 280 mm.
  • the distance between the bores 9 of a row is to be determined in such a way that a multiple thereof corresponds at most to the length of the longer side edge of the matrix field, e.g. the distance between two holes is 140 mm
  • a strip 10 is now attached to the upper side edge of the drawing board 1, in which the pins 2 are arranged in a row, this row running parallel to this side edge of the board.
  • the distance between two adjacent pins 2 corresponds exactly to the distance between adjacent holes in the plate 8.
  • This matrix Field 4 now has coordinates which in the virtual image of the computer are three times the distance between adjacent pins 2, ie here 420 mm, smaller in the horizontal X direction than the coordinates of matrix field 4 with field number "23".
  • the plotter 6 can be hung higher or lower, the vertical Y coordinates being changed by 280 mm in each case according to the embodiment according to FIG.
  • the plotter 6 now has a keypad 12. With this keypad 12 control commands for the drawing pen 6 can be entered. Depending on the command, this command is also sent directly to the computer via the Line 13 communicated Using the keypad 12, it can be entered, for example, that the drawing pen should draw a line in a certain direction and with a certain length starting from a predetermined point.
  • the drawing pen is moved in differently sized, graduated steps. Such steps are e.g. 100 mm, 10 mm, 1 mm and 0.1 mm each. If you want the pen to move along a line e.g. a total of 243.1 mm are moved, the drawing pen is moved twice by 100 mm using a "100 mm button", then four times 10 mm using a "10 mm button”, then three times using a "1 mm button” 1 mm and finally by a "0.1 mm button” by 0.1 mm. From this it can be seen that if the designer does not know the total length of the line to be drawn, he can "gradually" approach the end of the line.
  • the plotter 6 is always outside of the format of the drawing sheet with two of its side edges 3.
  • the pens 2, which align the plotter 6 with respect to the drawing board 1 are arranged next to the drawing sheet 3 around it on all of its side edges, while the plotter 6 either has holes 9 on its rectangular frame itself, as in FIG. 2 shown, or around this Rahman a peripheral strip is attached, in which the holes 9 are arranged.
  • a separate plate 8, as in the embodiment according to FIG. 1, is therefore not necessary here.
  • the distances between adjacent bores 9 and pins 2 are to be selected here analogously to the embodiment according to FIG. 1.
  • the plotter 6 can be fixed on two of its side edges opposite the drawing board 1.
  • this bar should also be made of a transparent material, e.g. consist of a plexiglass.
  • the edge of the plotter 6 should be as narrow as possible, since the parts of the drawing that are located below this edge cannot be seen by the designer.
  • the pins 2, which are attached to the drawing board 1 directly (FIG. 2) or indirectly (FIG. 1), are made of wear-resistant metal.
  • the strip 10 can also be made of metal in order to ensure sufficient stability thereof and permanent alignment of the pins 2 even over a long period of time.
  • the "bores" 2 described above are bores in a plexiglass plate 8 or circumferential plexiglass strip into which metal bushings are inserted.
  • the inner diameter of these metal bushings is matched to the outer diameter of the pins 2 so that there is a snug fit. This ensures the exact positioning of the plotter 6 relative to the pins 2 and thus relative to the drawing board 1. If after a long use of the drawing board 1 with the plotter 6 the play between the holes 9 and the pins 2 is too great, the metal bushings can be exchanged for new metal bushings. It is also possible to design the pins 2 to be interchangeable in order to ensure an exact fit when the pins 2 are worn.
  • a frame made of several strips is provided, each of which is parallel to the side edges of the plotter. Horizontal strips each have a number of bores 9, while the vertical strips ensure a connection of the bores 9 with the plotter 6.
  • the matrix fields 4 can also be classified differently than described above, in particular the matrix fields 4 can be significantly smaller than described above.
  • the entire drawing sheet can also be divided into matrix fields 4, which are horizontally and / or vertically displaced by exactly 100 mm from each other, although multiples of them then no longer match the DIN formats. However, the designer then has the opportunity to easily follow the coordinates even when the plotter is moved.
  • the plotter 6 can also be fixed to a known drawing machine instead of the drawing rulers, e.g. on this means, such as holes and pens, are provided in order to lock the drawing machine and thus the plotter in a particular position.
  • Such drawing machines must, however, be made more stable than is customary, since the plotter 6 has a much greater weight than the rulers otherwise used.
  • parallelogram drawing machine e.g. holes are provided in each strut of a pair of parallel guides, with a hole of the one guide strut being made to coincide with a hole of the other guide strut for each desired matrix field 4 and the like by means of a pin. be secured against each other.
  • a plotter is now fixed on the vertical rail of the drawing machine, particularly in a rotationally fixed manner.
  • the position of the plotter on the drawing board can now be determined by the measuring transducers, and the values obtained are transmitted directly to the computer
  • the plotter can e.g. can be moved by motor over the drawing board with stepper motors. It is also advisable to divide the drawing board into certain fields, e.g. the plotter is only moved in 100 mm steps along the vertical rail and the vertical rail along the horizontal rail. For this, e.g. a number of limit switches are provided in both the vertical and horizontal rails. The plotter is moved by actuating another switch until it has reached a certain limit switch assigned to the desired matrix field 4 on the drawing board
  • FIG. 3 shows a drawing board 1, on the vertical side edges of which strips 10 with bores 2 'are arranged, against which a horizontal strip 14 with bores 2 can be fixed. These strips 10 and 14 can be the rails of a drawing machine. On this bar 14, the plotter 6 can be fixed relative to the bores 2. The plotter also has 6 holes here. A pin 15 is inserted through appropriate holes in order to hold the plotter 6 relative to the drawing board 1. A hole spacing of 200 mm was selected here so that a total of 20 overlapping matrix fields 4 result.
  • the embodiment according to FIG. 4 uses a rectangular frame 16 which can be displaced and fixed horizontally relative to the drawing board 1, while the plotter 6 can be displaced and fixed vertically in this frame 16.
  • the hole spacing in the horizontal is 200 mm
  • the vertical hole spacing is 100 mm.
  • the format of the plotter 6 is taken into account, which is larger in the horizontal than in the vertical.
