Definitions

  • the invention relates to a method for producing a folding box blank, in which it is cut out of a cardboard sheet and at least one groove is pressed into it to form each folding line, and a device for carrying out this method.
  • the usual known method of this type is that for each folding line a deep groove is pressed in on the side of the cardboard sheet, which forms the outside of the folding box after folding.
  • This groove must be so deep that it emerges as a bulge on the side of the folding box blank that forms the inside after the folding box has been folded. Thereby folding becomes possible without tearing the material.
  • the folding box blank is punched out of a cardboard sheet by means of a punching tool which at the same time forms the grooves.
  • the base on which the cardboard sheet is placed must have channels for receiving the grooves embossed during punching. Both the punching tool itself and the base for punching out a folding box blank are relatively complicated tools to manufacture. For cost reasons, this known method is therefore unsuitable for the production of patterns for folding boxes.
  • a cardboard sheet is placed with the side on the form that later forms the inside of the folded folding box.
  • the cardboard sheet is then pressed onto the form plate by means of a cylindrically curved surface, so that the folding box blank is cut out and the grooves are pressed in at the same time.
  • the known folding box blanks for folding box patterns are therefore produced in such a way that the grooves necessary for folding are made by hand by the pattern maker in a blank cut from a cardboard sheet.
  • the folding box blank not yet provided with grooves is placed with the side that later forms the inside of the folding box on a template with a channel groove in such a way that the channel groove lies under the desired groove.
  • the pattern maker then embosses the groove into the outside of the box cut with a folding leg. Since a folding box blank has many grooves running in different directions, this process is very cumbersome and also expensive because of the high labor costs.
  • the invention is based on the object of specifying a method and creating a device by means of which folding box blanks can be produced in small numbers, that is to say for folding box patterns, with little effort.
  • the method according to the invention for producing a folding box blank consists in that a plotter with a computer system for computer-aided design and manufacture is used for cutting and pressing in the grooves and its computer system is preprogrammed such that its holder is longitudinal after a first and a second program Paths is guided, which correspond to the course of the grooves or the outline of the folding box cut, that the cardboard sheet is detachably held on the uninterrupted surface of the table of the plotter, that a printing tool is inserted into the holder of the plotter and the plotter is switched on, so that when Carrying out the first program of the holder moves the printing tool along the preprogrammed paths and thereby presses in the grooves, that the printing tool in the holder is then exchanged for a cutting tool and, when carrying out the second program, the holder moves the cutting tool along the outline and thereby the groove provided folding box cut out.
  • “Plotter” is understood here to mean a machine which, like an EDP system-controlled drawing machine, has a table and a holder which can be moved over the table according to XY coordinates.
  • the cardboard sheet is placed on a smooth surface, namely the surface of the plotter table, and then the grooves are pressed in by a printing tool guided over the surface of the cardboard sheet, the folding box blank produced in this way along the folding lines defined by these grooves can be folded properly.
  • Particularly advantageous conditions result when the cardboard sheet is placed with one side on the plotter's table and at least two mutually parallel grooves are pressed into the other side of the cardboard sheet for each folding line of the folding box blank,
  • the folding box blank of cardboard shown in FIG. 1 has, on the side which forms the inside of the folding box after folding, groove pairs 11 formed from mutually parallel grooves 10. As can be seen from FIG. 2, the groove depth is less than half and the distance between the groove centers from one another is approximately twice the cardboard thickness. Through these grooves it is achieved that the inner cardboard surface 12 of a folding box made from the folding box blank bulges slightly between the two grooves 10 of each pair of grooves 11. This has the consequence that when the carton is folded around the fold lines defined by the pairs of grooves 11, the inner carton surface 12 forms a bulge, as is shown enlarged in FIG. At the same time, the locations on the outside of the carton opposite the bottoms of the two grooves 10 form the crease lines 13 shown in FIG. 3, which delimit the flat areas 14 on the outside of the folding box.
  • the folding box blank according to FIG. 1 described above is a preferred embodiment. Instead of two grooves 10 forming a groove pair 11, only one or more than two, e.g. three grooves may be provided. The grooves can also be pressed into the side that later forms the outside of the folding box.
  • a conventional EDP system-controlled drawing machine can be used for the machine for producing the folding box blanks shown in FIG. It is therefore briefly referred to below as a plotter and accordingly has an uninterrupted flat table surface of a table 20 which has parallel rails 21 and 22 on two opposite longitudinal sides, on which a carriage 23 extending over the table 20 along one in the Drawing with X designated coordinate is movable.
  • a carriage 24 is displaceable through transverse rails 25 and 26 perpendicular to the X axis, that is to say along the axis designated Y in the drawing.
  • the carriage 24 carries a holder S8, in which, as with the plotter. a drawing pen or the like, a printing tool or a cutting tool can be used.
  • This holder 28 can be moved up and down along the axis designated Z in the drawing, perpendicular to the surface of the table 20, and is rotatably mounted in the slide 24 about the Z axis.
  • the table top can be made of a porous material, so that cardboard sheets placed on the table can be detachably held thereon by applying a vacuum to the underside of the table top.
  • the four arrows 30 shown in Fig. 4 are intended to indicate such a means for holding the cardboard sheet on the table top, which means both by said vacuum or by another, e.g. mechanical means can be realized.
  • the plotter shown in simplified form in FIG. 4 has drives, not shown in the drawing, for the translational movement of the carriage 23 along the X axis, for the translational movement of the carriage 24 along the Y axis, for the translational movement of the holder 28 along the Z axis and for the rotation of the holder 28 about the Z axis.
  • the schematic diagram according to FIG. 5 shows an EDP system 35 for computer-aided design and manufacture with a screen 37 and the drive controls 31, 32 and 33 for the translational movement of the carriage along the X axis, the carriage along the Y axis and of the holder along the Z-axis and a controller 34 for rotating the holder 28 about the Z-axis.
  • the desired folding lines and cutting lines can be arranged exactly with respect to one another, so that the preprogramming for the EDP system for performing the movements of the holder for pressing in the grooves and for cutting out the folding box blank results.
  • the EDP system must therefore be preprogrammed for two different programs, namely for a program for producing the grooves 10 and for a second program for cutting out the folding box blank, which run in succession with the appropriate tools, and also an automatic changing device, not shown in the drawing can be provided, which automatically exchanges the tool for pressing in the grooves against a cutting tool after the end of the first program and then allows the second program to run.
  • FIG. 6 shows a simplified view of a printing tool 40 for producing two mutually parallel grooves 10.
  • This tool has a shaft 41 which can be inserted into the chuck of the holder 28 and which is provided with a slot 42 around the shaft 41 in a rotationally fixed manner with the holder 28 to connect.
  • a pressure roller 43 is connected to the shaft 41 so as to be rotatable about an axis 24 perpendicular to the shaft and thus to the Z axis of the holder 28 and has two beads 45 which are provided for simultaneously pressing grooves 10 parallel to one another.
  • a ball 47 which is rotatably mounted on all sides at the lower end of the shaft 41 is provided.
  • a construction corresponding to the known ballpoint pens can be used for this printing tool.
  • This embodiment has been particularly well suited. While the holder 28 must be rotated about the Z-axis in the embodiment according to FIG. 6 for pairs of grooves which form angles with one another, this is not necessary in the embodiment according to FIG. 6A.
  • the control of this printing tool 40" must correspond to the control of the Pressure tool 40 according to Figure 6 take place, ie here, too, the tool for indenting grooves that form angles with one another must be rotated about the Z axis.
  • a cutting tool 50 is shown only schematically in FIG. 7, which has a shaft 51 which, like the shaft 41 of the printing tools, has a slot 52 in order to connect it to the holder 28 in a rotationally fixed manner.
  • a circular knife 53 is rotatably mounted about the axis 54 perpendicular to the Z axis.
  • a fixed knife can also be provided, which is guided in a tangential cut over the cardboard sheet.
  • the computer system 35 is first preprogrammed with the aid of the screen for the two programs for producing the grooves 10 and for cutting out the folding box blank. Then a cardboard sheet 46 is placed with the side on the table surface of the plotter table 20, which later forms the outside of the folded folding box. After a printing tool 40, 40 'or 40 "has been inserted into the holder 28, the first programmed program of the computer system is run so that the grooves 10 are pressed in pairs for each folding line without them being on the outside of the Then use a cutting tool, such as a milling cutter, a tangential knife or a circular knife 53 (Fig.
