Definitions

  • the invention relates to a device for monitored tablet filling.
  • the invention has for its object to provide a device for supervised tablet filling, which works very reliable, in which an extremely fast quantitative examination of the tablets during the filling process is possible and excluded by a sorting good tablets, and a corresponding method for supervised Indicate tablet filling.
  • the monitored tablet-filling device has a device for feeding tablets into a drop-down path and a capacitive sensor for checking each falling tablet in the drop-down path.
  • it has a separating device for separating good and bad tablets, which is arranged below the sensor in the drop section, and a control device, which is connected to the sensor and the separating device and controls the separating device on the basis of the values supplied by the sensor.
  • the senor has a voltage generator for a high-frequency alternating electric field, two opposing, vertically extending and from the voltage generator respectively briefly opposite charged capacitor plates and an ammeter.
  • the alternating electric field preferably has a frequency of between 500 kHz and 10 MHz, more preferably 1 MHz.
  • the senor is capable of detecting more than 1,000 tablets per minute.
  • the sensor is preferably also suitable for recording the data of a tablet within a time window of less than 100 ms, preferably less than 50 ms, more preferably less than 10 ms, which enables the exact and rapid activation of the separating device.
  • the capacitor plates have a height of between 5 and 20 mm, preferably 10 mm, and have a distance of between 5 and 30 mm to each other, but at least 10% larger than the tablet width.
  • the device also comprises a camera, which is arranged above the sensor and is connected to the control device.
  • the controller is designed to use the values provided by the sensor and the information provided by the camera on a particular tablet as a common basis for controlling the separator. Thus, not only tablets are discarded which have a wrong mass, but also, for example, tablets of correct mass, which have a different color.
  • the separating device is designed as a blowing device, which directs a lateral air blast on selected falling tablets.
  • the method according to the invention for monitored tablet filling comprises the following steps: feeding tablets into a drop zone, checking each falling tablet in the falling distance by means of a capacitive sensor, and controlled separation of good and bad tablets below the sensor in the falling distance on the basis of the values supplied by the sensor.
  • Fig. 1 shows a schematic view of an embodiment of the device according to the invention for monitored tablet filling.
  • the device comprises a feeding device 2 for tablets 4, which is usually designed as a vibratory conveyor.
  • the tablets are already singulated by the feeder 2.
  • the tablets 4 pass into a drop zone 6, through which they fall into can-like or bottle-like containers 14.
  • the containers 14 are transported by means of a conveying device 20.
  • a sensor 12 for receiving quantitative properties, in particular the mass of the tablets 4, is arranged in the fall section 6, here in the upper edge region of the drop section 6.
  • the sensor 12 conveys, as will be described in more detail below, the measured values to a control device 7, which in turn is aligned immediately afterward, ie within 10 ms, a control command to a separator 8 based on the values transmitted by the sensor 12 to send.
  • the separating device 8 ensures a separation of good and bad tablets 4. In the present example, bad tablets 4 are actively sorted out, but it is also conceivable that each good tablet 4 is actively conducted into the container 14 by the separating device 8.
  • the separating device 8 is preferably a blowing device which specifically directs an air jet from the side onto a specific tablet 4. Such a blowing device has the advantage over mechanical devices that the reaction time is significantly shorter and thus the accuracy is ensured even at high throughput of the filling device.
  • the bad tablets 4 end up in a reject container 9a.
  • the control device 7 preferably takes into account the size and speed of the respective tablet 4 on the basis of previously recorded calibration values. Due to the high speed of the sensor 12, the control device 7 and the separator 8, the separator 8 may be located near below the sensor 12.
  • a camera e.g. a color camera
  • the controller 7 may also be used by the controller 7 to control the separator 8.
  • the image data may require a longer processing time than the sensor data. This allows both a discharge of tablets 4 with different mass (via the sensor 12) and with a different color (via the camera 11) can be achieved.
  • a filling control 9 can be activated by the control device 7 when a certain number of good tablets 4 has entered a container 14. It is possible that the filling control 9 upon complete filling of a container 14 via movable filling means 10, for example via a pivoting of feed channels or the temporary closing and reopening of a storage flap in the feed channel, a filling of the next container 14 initiated.
  • the conveyor device 20 is preferably moved clocked, so that the next container 14 is brought into the filling position.
  • the sensor 12 is designed as a capacitive measuring sensor and comprises two vertically extending, opposing capacitor plates 15, 16, between which tablets 4 fall through.
  • the capacitor plates 15, 16 are charged in opposite directions by a voltage generator 13 for high-frequency alternating voltage in very short distances.
  • the frequency is between 500 kHz and 10 MHz, preferably 1 MHz.
  • the charge states of the capacitor plates 15, 16 are respectively represented when opposing voltage concerns. In the left section, the capacitor plate 15 is positively charged and the capacitor plate 16 negatively charged, while in the right section, the capacitor plate 16 is positive and the capacitor plate 15 is negatively charged.
  • the change in the applied voltage U generator (t) results in minimal polarization changes in the tablet 4, which in itself represents an insulator, in the alternating electric field. These minimum polarization changes can be accommodated by an ammeter 18.
  • the measured current I M (t) is proportional to the number of charged particles in the tablet 4. Even during the fall, and thus the extremely short time during which each tablet 4 is in the region of the sensor 12, excellent results are obtained.
  • the constant acceleration of the tablets 4 also has no negative effect on the measurement result.
  • the capacitor plates 15, 16 have a height of between 5 and 20 mm, preferably 10 mm, and have a spacing of between 5 and 30 mm to each other, but preferably at least 10% greater than the tablet width.
  • corresponding reference models must first be included for the respective tablet type in order to calibrate the sensor 12 for the relevant field of application.
  • an analysis of more than 1,000 tablets per minute can be made, with the data of a tablet 4 being received by the sensor 12 within a time window of less than 100 ms, preferably less than 50 ms, more preferably less than 10 ms.
