Definitions

  • the present invention relates to a tablet press according to the preamble of claim 1 and to a method for producing a tablet according to the preamble of claim 10.
  • a station-wise rotating tablet press of this type with a filling station, a pressing station and an ejection station.
  • a table with die shapes rotates indexed from the filling station via the pressing station to the ejection station when a tablet is manufactured.
  • the lower punch is moved out of the die shape, which contains a pressed tablet, and the pressed tablet is pressed down by a ejection pin from above through the die shape onto a passing conveyor belt.
  • the known tablet press tends to become soiled or sticky when compressing filling material with sticky natural materials, which can lead to malfunctions in the operating sequence.
  • the invention is based on the object of developing a simply constructed, reliable and easy-to-use rotary tablet press operating in stations and a corresponding method for producing a tablet, the reliability of which should also be ensured when processing contents with sticky natural substances.
  • a coupling unit is provided here, which can couple the drive unit to and decouple it from the rotary unit.
  • the transmission of a drive movement from the drive unit to the rotating unit can hereby be suspended, so that the rotating unit stands still.
  • the coupling unit also allows only certain drive movements to be passed on from the drive unit to the turntable, which increases the range of usable ones Drive systems expanded. If necessary, decoupling also enables the rotating unit to be moved manually with little effort, without simultaneously moving the drive unit.
  • a control plate for curve control of the lower punch position can be provided. This enables precise positioning of the lower punch in the die shape in and between the individual processing positions of the tablet press.
  • a loading device can press the lower punch against the control plate. This increases the positional accuracy of the lower punch in the form of the die, since the connection between the control plate and lower punch is always ensured.
  • the loading device can advantageously be arranged within the rotating unit. This increases the reliability of the loading device, since its protected position within the rotating unit means that there is a reduced risk of contamination due to contents or contamination from the environment.
  • the lower punch can be lowered in its position immediately after the pressing in comparison to its end position during the pressing. This creates a distance between the lower punch and the pressed tablet, thereby preventing the pressed tablet from being subjected to any further force. In some embodiments, this facilitates rotating the turntable.
  • the lower punch can be designed as an ejector for a pressed tablet.
  • the lower punch reliably transports the pressed tablet out of the die form.
  • the die shape is cleaned by the lower stamp when ejected
  • the coupling unit can decouple the drive unit from the rotary unit in a machining position.
  • the rotating unit is thus stationary in the processing position and a processing step for producing the tablet can be carried out.
  • the drive unit can have a linear actuator. It has been shown that, in addition to the standard rotating drive systems, a reliable and indexed rotation of the turntable can also be achieved with a linear actuator.
  • the drive unit can have a first and a second linear actuator, the two linear actuators working in opposite directions. It has been shown that the rotary unit can be rotated in both directions, if desired, by means of two linear actuators operating in opposite directions without having to use more complex rotating drive systems. The use of two linear actuators working in opposite directions also makes it possible to design the linear actuators with a single action.
  • An indexing unit can advantageously be provided, which locks the rotating unit in a processing position.
  • the turntable is positioned exactly in the machining position and secured against unintentional movement in the machining position, which increases the reliability of the manufacturing process.
  • a filling channel can be provided, in which the filling material is fed to the die shape. This ensures reliable feeding of the filling material to the die shape.
  • the filling channel can cover an area of a movement path of the die shape. This improves the degree of filling and the state of filling of the die form, particularly in the case of sticky filling material, since the filling material is given more time to get into the die form during the rotation of the die form.
  • the rotating unit and the filling channel can press against one another in a prestressed manner. In this way, a secure contact between the rotating unit and the filling channel is achieved, which increases the reliability of the supply of filling material to the die shape.
  • a pressing force generation unit can be arranged below the rotating unit. This arrangement improves the accessibility to the tablet press in the area above the rotating unit.
  • the pressing force generating unit can pull an upper punch towards the lower punch during pressing. Pulling the upper punch enables an advantageous arrangement of the upper punch, lower punch and pressing force generating unit in one line of action.
  • the pressing force generating unit can have a pressure cylinder and at least one further pressure cylinder, one pressure cylinder pulling the upper punch during pressing from a starting position towards the lower punch and the at least one a further pressure cylinder moves the upper punch back to its starting position after pressing.
  • the pressing force generating unit has only one of the pressure cylinders, that is to say the pressure cylinder which pulls the upper punch toward a lower stamp from a starting position or the at least one printing cylinder which moves the upper punch back into its starting position after pressing.
  • the use of a pressure cylinder for pressing enables the most constant and therefore gentle generation of pressing force for molding the tablet, which in particular reduces the release of sticky substances when pressing natural materials.
  • the use of a pressure cylinder to move the upper punch back allows the upper punch to be moved back with little resistance.
  • the at least one pressure cylinder which moves the upper punch back into its starting position after pressing, can be made smaller than the printing cylinder, which pulls the upper punch towards the lower punch. Since the working volume of the at least one printing cylinder for moving the upper punch back is smaller than the working volume of the printing cylinder for pressing, the response time of the smaller printing cylinder can be reduced compared to that of the larger printing cylinder, which means the duration for moving the upper punch back and thus the total duration shortened to make a tablet.
  • the filling volume of the die shape can be changeable. This allows different tablet sizes or tablet densities to be produced with the same die shape.
  • the filling volume of the die shape can be changed via the position of the lower punch.
  • the tablet size and / or tablet density can thus be set reliably and precisely by raising or lowering the position of the lower punch in the die form.
  • the filling volume of the die shape can be changeable during the rotation of the rotating unit. This enables a time-saving and simple adjustment of the filling quantity or the tablet size and / or the tablet density.
  • the tablet press can be driven pneumatically.
  • air as a fuel reduces the risk of dust explosions compared to electrical drives and contamination of the tablet by the operating fluid compared to hydraulic drives.
  • a drive unit rotating the rotating unit is coupled and uncoupled to the rotating unit.
  • the lower punch can be lowered immediately after pressing in comparison to its end position during pressing. This creates a distance between the lower punch and the pressed tablet, thereby preventing the pressed tablet from being subjected to any further force. In some embodiments, this facilitates rotating the turntable.
  • the tablet can be ejected from the lower punch.
  • the pressed tablet is reliably transported out of the die form by the lower punch.
  • the die shape is cleaned by the lower stamp when ejected
  • the turning unit and a drive unit can be decoupled from one another in a machining position.
  • the transmission of a drive movement from the drive unit to the rotating unit can hereby be suspended, so that the rotating unit stands still and a processing step can take place.
  • the die shape is filled along a filling channel. This improves the degree of filling and the state of filling of the die form, since the filling material has more time to get into the die form during the rotation of the die form along the filling channel.
  • an upper punch is pulled towards the lower punch during pressing.
  • the pulling of the upper punch enables an advantageous arrangement of upper punch, lower punch and a unit generating the pressing force in an effective line.
  • the rotating unit rotates, the filling volume of the die shape being changeable at the same time. This enables a time-saving and simple adjustment of the filling quantity or the tablet size and / or the tablet density.
