Definitions

  • the invention relates to a set of press punches for a tableting machine according to the preamble of claim 1.
  • a die plate which is usually driven about a vertical axis, has dies arranged on a circle, to which pairs of press rams which are synchronous with the plate are assigned.
  • the press rams are actuated by control cams and pressure rollers.
  • the lower punch of a pair forms the bottom of a mold cavity, its height in the die dictating the dosage. This is followed by pressing opposing rams in a pressing station towards one another and compressing the tablet material to a desired thickness (web height).
  • the lower punches controlled by an ejector curve, push the tablet out of the die at a certain point on the machine, while the opposite row of punches (upper punch) gradually moves away from the die plate.
  • a scraper can strip off the discarded compacts from the die plate and feed them to a discharge channel.
  • the control of the tabletting machine and its monitoring ie the control of the speed, the fill level control, the pressing force of the punches, the control of the web height, the sorting out and the drawing of samples etc. is carried out via a process computer.
  • a process computer With a single rotary press, different compacts can be produced in shape, thickness and size, with different dies and press die sets being necessary for different geometrical dimensions, with the exception of certain ones Web height deviations (the latter can be changed by the pressure or the stroke of the ram). If matrices and press die sets are now exchanged on a tableting machine, the computer must be reprogrammed accordingly. This requires careful work so that the wrong program is not accidentally entered or selected.
  • a tool or tool holder in particular for machining on numerically controlled machining centers, has become known, in which a data carrier in the form of a permanently installed, electrically erasable and programmed memory is accommodated in a blind hole of the holder or the tool is.
  • the memory contains various tool-specific characteristics, such as length, diameter, tool life and the like parameters.
  • the memory has contacts that are used for power supply and for querying, deleting or setting the memory.
  • the memory is read with the aid of a displaceable stamp which is inserted into the blind hole while the tool or the holder is held by gripper arms.
  • the invention is therefore based on the object of providing a set of press rams for tableting machines which can be incorporated into the process control operation of a tableting machine.
  • a press stamp of a set is provided with a recess on the shaft in which a data carrier is received.
  • the data carrier is preferably an IC component, which is accommodated in a suitable manner in the recess of the stamp shaft.
  • the recess is preferably adjacent to the stamp head.
  • the ram carrying the data carrier is assigned to a reading device which can be arranged on the tabletting machine itself or outside.
  • Press tools are checked for dimensional accuracy after use in a suitable device.
  • the functional length and diameter of the entire press tool set are checked and documented.
  • This data can therefore also be taken into account when operating the tabletting machine.
  • each press die with an appropriate coding. Then it is irrelevant in what order the press punches of a set are fed to the reading device or guided along a reading device arranged in the tabletting machine. in the In principle, however, this effort is not necessary, since the stamps of a set are identical. It is only necessary to make the press stamp having the data carrier sufficiently identifiable so that it can be picked out either manually or automatically and brought into relation to the reading device.
  • the press stamp which has the data carrier can be provided with a suitable marking or printing.
  • the upper and lower press rams are axially movable in disks, they are therefore already kept in stock in this way of installation, it is also possible to provide a corresponding rotary bearing for the disk, with which the disk can be set in rotation, so that the individual Press rams are guided along the reader before the disk with the press rams is installed in the tabletting machine. It is only essential for this that the press die holding the data carrier is oriented in such a way that the data carrier is aligned with the read head when the press die in question is in the region of the read head.
  • the reading device As soon as the reading device has read the data from the data carrier, they are transferred to the process computer, which then selects the program belonging to the press ram set, whereby the tabletting machine is ready for operation is as soon as the press ram set has been installed.
  • the press rams 10a and 10b shown in FIGS. 1 and 2 have a head 12a, 12b, a neck 14a, 14b, a shaft 16a, 16b and a press section 18a, 18b.
  • the pressing sections 18a, 18b differ, the latter using a Retaining cap 20 is attached to the lower end of the shaft 16b.
  • Each of the punches 10a, 10b belongs to a set of punches as are used in so-called rotary presses for tableting machines and as are generally known.
  • a rotary press includes a lower and an upper set of press rams.
  • Each die form requires the special setting of data for the automatic control of the machine, the process data being programmed in a memory of the process computer.
  • Data carriers 22a, 22b are embedded in the shaft of the press rams 10a, 10b near the neck 14a, 14b.
  • a circular recess 26 is provided for receiving the chip 22a. As can be seen, it closes with the outside of the shaft 16a.
  • the data typical of the press ram or a code are stored in the chip 22a or 22b. These are identified by a suitable reading device and passed on to the process computer (not shown) so that the necessary control data are completed after the installation of the set or sets of press dies.
  • FIGS. 4 and 5 show two possible reading devices, which are largely the same, so that the same parts are provided with the same reference numerals.
  • a housing 30 has a receiving bore 32 for receiving a press die 10c, which is provided with a data carrier or chip 22c in the manner described above.
  • the press ram 10c is brought into the correct rotary position by suitable precautions. For this purpose, it can be provided with a suitable marking, not shown, whereby the operator can align this marking with a marking, also not shown, in the reading device.
  • an automatic orientation of the press ram 10c is also possible, so that it assumes the correct rotational position with respect to a reading head 34 which is received in a further bore 36 in the housing. 5, the reading head 34 is fixed in the bore 36 by a locking screw 38, which interacts with a groove 40 in the reading head 34.
  • This embodiment is only possible for chips 22c in which contactless reading can take place.
  • the reading head 34 is movably mounted against a spring 42 in the bore 36, a limiting screw in a movable component 46, which has the bore 36, being movable to a limited extent in an elongated hole 48 of the housing 30. With a stroke of 5 mm, for example, the contacts of the read head 34 brought into contact with the contacts of the chip 22c.
  • the data is then transmitted from the chip 22c to the process computer (not shown) via a signal cable 50.
