Definitions

  • the invention relates to an ironing machine with a computer-assisted control device and an upper and a lower mold plate. which each have an ironing surface on their mutually facing sides and can be moved horizontally relative to one another and in which at least the upper mold plate can be moved vertically via a pressure cylinder. (see US-A-4,862,608).
  • DE 39 39 024 C1 describes an ironing machine of the type mentioned which is equipped with a measuring device in order to determine the shortest distance between the upper mold plate and the goods to be ironed placed on the lower mold plate.
  • the determined distance value is further processed in a computer, which determines the optimum ironing pressure and the corresponding ironing time for the items to be ironed and outputs them to a pneumatic or hydraulic control device.
  • the measuring device is preferably equipped with non-contact rangefinders with optical sensors or ultrasonic sensors, and the pressure and time values can be specified on the computer in adaptation to the different types of substance.
  • the invention has for its object to improve ironing machines of the type mentioned in such a way that no errors occur when setting the ironing pressure with reference to the respective ironing material, in particular due to the pressure of the weight of different upper mold plates each adapted to the ironing material.
  • the solution according to the invention to the problem shown is characterized by a differential pressure control device which takes into account the weight of the respective upper mold plate, if appropriate including accessories, such as piston rod and fittings, in relation to the ironing surface when computer-controlled pressurization of the ironing goods.
  • the invention prevents the weight of the upper mold plate from being transferred to the goods (textile material) in an uncontrolled manner when the upper mold plate is fed against the lower mold plate, i. H. if, with increasing pressure on the upper cylinder chamber of a pressure cylinder displacing the upper mold plate, the associated lower cylinder chamber is strongly vented.
  • the weight of the upper mold plate can be, for example, 20 to 120 kg, depending on the size of the ironing surface and the desired preforming.
  • the differential pressure control device for ironing machines in combination with the controlling arithmetic unit provides, in particular, in the computer to keep the pressure value required in relation to the respective piston surface of the press cylinder of the upper mold plate in balance with the weight of the respective mold plate or the pressure value to be programmed and loaded in to bring a balance in everyone Driving position of the printing cylinder is maintained in a controlled manner.
  • the single figure shows a schematic representation of an ironing machine in which the differential pressure control device according to the invention is provided in connection with the upper mold plate.
  • the drawing shows an upper mold plate 10 and a lower mold plate 16.
  • the upper mold plate 10 is connected via one (or more) piston rod (s) 7 to the piston (s) 9 of a pressure / lifting cylinder 8 (several pressure / lifting cylinders) .
  • the vertical position of the piston 9 is determined in a known manner by different pressure conditions in an upper pressure chamber 12 and a lower pressure chamber 13. These pressure conditions or pressure differences are determined and controlled by a computer 11.
  • a first pressure sensor 5 is connected to the lower pressure chamber 13 and a second pressure sensor 6 is connected to the upper pressure chamber 12.
  • the pressure values determined by the pressure sensors 5, 6 are sent as two input signals to the computer 11, which determines the pressure values for the upper pressure chamber 12 and the lower pressure chamber 13, taking into account the respective dead weight of the upper mold plate (including the associated piston rod 7 and piston 9) , in such a way that an optimal ironing pressure or the correct ironing time are automatically set taking into account the respective ironing material.
  • the pressure chambers mentioned are each connected to a pair of a ventilation valve 1, 2 or 3, 4.
  • the ventilation valves 1 and 4 are connected to a pneumatic or hydraulic pressure source 15 (not shown), while the ventilation valves 2 and 4 with a pneumatic pressure source, if necessary, via appropriate filters. Ventilate pressure reducing lines and silencers to atmospheric pressure, while in the case of a hydraulic system, ventilation valves 2 and 3 are connected to a corresponding vacuum tank.
  • the valves 1 to 4 are electromagnetically actuated Valves whose control signals, as shown in dashed lines, are supplied by the computer 11.
  • the counterpressure values required in relation to the piston area to compensate for the weight of the upper mold plate 10 are entered in the computer 11 via an adjusting unit 17.
  • the schematically indicated pressure value P9 thus corresponds to the mold plate weight, divided by the piston area of the lower pressure chamber 13.
  • the "programming pressure" in N / cm 2 (p / cm 2 ) [of the mold plate surface] is implemented on a corresponding digital display during programming.
  • a very precisely controlled pressurization in the upper or lower pressure chamber of the cylinder 8 can thus be achieved via the electromagnetic valves 1 to 4. This applies to every vertical position of the piston 9, except when the piston 9 lies directly on the cylinder base.
  • the invention is not limited to ironing machines in which only the upper mold plate can be moved vertically, although this embodiment will be by far the most common. It is apparent to the person skilled in the art that the invention can also be used on ironing machines in which either only the lower mold plate or in which both mold plates can be moved towards one another in the vertical direction. In the case of an ironing machine in which only the lower mold plate can be moved vertically, the considerations shown above for taking into account the weight of the respective mold plate with the opposite sign are of course to be taken into account.
