Definitions

  • the invention relates to an optical monitoring device for rotary presses according to claim 1.
  • Rotary presses such as those used for the production of tablets, have a rotor, the upper and lower punches leads and contains a die plate, with their holes cooperate the ram.
  • the rotor is driven by a suitable drive about a vertical axis.
  • the rotor is assigned at least one filling device which fills the powder to be pressed into the die bores.
  • at least one printing station is provided with upper and lower pressure rollers, which press the associated press dies into the die bores.
  • the rotor is further associated with a Auswerfstation in which the ejected compacts are removed from the rotor.
  • the ejection station can also contain a switch to separate good from bad compacts or even eject a number of test compacts.
  • Such a rotary press is usually housed in a housing, so that process dust does not penetrate to the outside and on the other hand, contamination of parts of the press is prevented by contaminated atmosphere of the environment.
  • sensors can be assigned different sensors to such a rotary press. For example, the pressing force exerted by the pressure rollers on the press dies is measured to bring them to a desired value.
  • the pressure rollers can by a suitable adjustment be adjusted.
  • a temperature sensor can be arranged in the housing or a sensor with which the composition of the material to be compressed or the concentration of individual active ingredients can be determined.
  • sensors may be provided which monitor the proper assembly of the individual parts of the rotary press.
  • the sensors are usually connected to an operating computer of the rotary press.
  • the operating computer is connected to the rotary press via a cable. However, instead of a cable, wireless transmission of signals from the sensors to the operating computer and vice versa can take place.
  • the invention has for its object to provide an optical monitoring device for rotary presses, with the fast-running manufacturing can be detected at any location of the rotary press.
  • At least one high-speed camera is arranged in the housing of the rotary press, the lens is directed to a location in the housing and which is connected to an image evaluation device.
  • the high-speed camera can be arranged at process-relevant positions within the rotary press, z. B. on the tablet drain, tablet scraper, in the Aussortierposition of bad tablets, in the filling area for the matrices in the heads of the ram in the upper and lower space for the cams for the ram, etc.
  • the signals of the high-speed camera which preferably operates digitally, can be given to the control and / or control computer of the rotary press, which are provided in any case in a rotary press.
  • the production process can be optically monitored.
  • An optical monitoring can z. B. also with regard to the punch heads take place, the high forces in the printing stations are satjust.
  • the high-speed camera is preceded by an endoscope, which is directed with its lens to the location to be monitored.
  • an endoscope which is directed with its lens to the location to be monitored.
  • the process space of the rotary press is enclosed by an inner housing, which is in sealing engagement with substantially only the portions of the rotor on the top and bottom of the die plate.
  • the high-speed camera is located outside the process room and the endoscope is sealed into the process room.
  • the punches and die plate remain in the rotary press during cleaning.
  • the end of the endoscope facing the location to be monitored also remains within the process space and is subjected to the cleaning process.
  • the camera itself is disconnected from the contaminated atmosphere in the process room and can therefore work trouble-free.
  • a blowing device can direct air against the objective and keep it away from dust.
  • the single FIGURE shows in a developed view schematically a rotary press with an optical monitoring device according to the invention.
  • a rotor for a rotary press by a die plate 10 an upper punch holder 12 and a lower punch holder 14 are shown, which are usually connected together in one unit.
  • the rotor formed in this way is driven about a vertical axis by a suitable drive motor (not shown here).
  • the punch guides 12, 14 carry upper punches 16 and lower punches 18, respectively, and their heads cooperate with upper curve elements 20 and lower curve elements 22.
  • the area between the punch holder 12 or 14 and the curve elements 20, 22 is referred to as upper curve space 24 or lower curve space 26.
  • a dispenser 28 which supplies stencil bores 30 with powder to be pressed, as shown.
  • Two successive printing stations 32 and 34 each include an upper and a lower pressure roller, which cooperate with heads of the plunger 16, 18 to compress the powder located in the die holes 30.
  • the dark-drawn compacts are ejected by means of the lower punches 18 and directed by means of a scraper 36 to a product outlet 38.
  • the scraper 36 is also able to sort out bad tablets, which are led out via a bad drain 40.
  • a high speed camera 42 is further shown, which looks into the process space via an endoscope 44.
  • the camera is suitable for use in dark or low-light environments and to produce well-resolved images at high process speeds.
  • the lower end of the endoscope 44 is directed with its lens on the stripping device.
  • the endoscope is supplied with light by a light source 46, and the high-speed camera 42 is connected to a control computer 48 for the rotary press shown.
  • the operating computer 48 is arranged on the machine or at a location remote from the rotary press. The connection is either via a cable or via a wireless communication link.
  • a housing 50 is provided which surrounds a process space 52.
  • the housing 50 is sealingly engaged with the upper and lower punch receivers 12, 14.
  • the endoscope is sealed into the process space 52.
  • the high-speed camera 42 is outside the process space 52.
  • the area of the stripping device 36 can be monitored. Furthermore, an adjustment of the scraper can be made, if this proves necessary, for. B. from outside the encapsulated process space.
  • optical monitoring as shown in connection with the stripping device 36, also to any other location of the shown concentric press inside and outside the process chamber 52 can be used to control, for example, also functions of the rotary press or to regulate.
  • the stamps can be monitored, for. B. on crashes or burglaries.
  • a blowing device 60 which directs air against the objective of the endoscope via a nozzle 62 in order to keep the objective dust-free.
