Definitions
- the invention relates to a device for Fixing the dies in the die table of one Tableting machine, in particular rotary tableting machine, by means of die holders.
- Modern tableting machines are suitable for that various types and forms of tablets press. After manufacturing one or more batches Batches of tablets have to be pressed by the pressing unit Disassembled for cleaning purposes and then assembled become. Disassembly is also necessary when the machine from a tablet format to a another tablet format is converted. To do this Stamps and dies are exchanged.
- Tableting machines in which the matrices are the radially from the outside into the die table are screwed in, fixed and locked or are detachable, see e.g. DE-A-1454820
- matrix screws are on front end conical and grip when screwing in for fixing the dies with the conical end in Circumferential grooves of the dies.
- the invention is therefore based on the object To create device with which both a quick Loosen the old dies as well as fast fixation the new dies in the die table is possible.
- FIG. 1 shows a vertical partial section through a rotary tablet machine 12. This consists of a die table 4 which is connected to a rotor 1 over a vertical rotor axis 14 rotating drive shaft 13 is driven and off Upper rotor part 15 and lower rotor part 16 is formed, in which upper stamp 3 or lower stamp 2 are performed are.
- the upper stamp 3 is by means of a Guide bushing 26, which is designed with a groove, and a key 25 adjusted.
- the guide bush 26 of the upper punch 3 is with a fitting 23 associated screw 24 attached.
- Even the lower stamp 2 is by means of a guide bush 27 and a key 25 adjusted.
- the attachment of yourself lower punch 2 located in the guide bushing 27 is carried out by means of adapter 23 and screw 24.
- dies 10 are evenly on the pitch circle 17 of the die table 4 is arranged. If during operation of the rotary tablet machine 12 the die table 4 rotates, the dies 10 arrive with their associated upper stamps 3 and lower stamps 2 in succession to a press station, where with the help of Pressure rollers that are in the die 10 Filling material is compressed to the finished tablet.
- the Press station and pressure rollers are not in Fig.1 shown. The same applies to the filling shoes, whose The task is to fill the material after the pressing process into the empty die 10 afterwards.
- Each die 10 consists of a metallic one Die body 18 and a through opening 19, which forms the shape for pressing the tablet, and has an annular groove 11 on the outer circumference.
- a hydraulic piston 20 with conical clamping head 21 executed and with a lengthening die pin 6 provided against a Spring 8 of a screw plug 7 presses. This is in a radial bore 22 in the die table 4 from the outside screwed tight.
- the pressure force of one is not Hydraulic device shown is by means of a pressure feed 9 guided by the rotor 1 simultaneously on the piston-like die holder 5 transfer.
- the die table 4 shows a partial top view of the die table 4.
- the matrices 10 are even distributed on the pitch circle 17.
- the die holder 5 are designed as hydraulic pistons 20, at the End the matrix pins 6 are arranged.
- Of the conical clamping head 21 of the die holder 5 engages when fixing in the ring grooves 11 of the dies 10.
- Two die holders 5 each wedge one Die 10 so that it is against a vertical and axial displacement during the pressing process is secured. Because a die holder 5 in each to the left and right of it arranged ring grooves 11 Engages matrices 10, the same number of Die holders 5 need like dies 10. From the outside are the screw plugs 7 in the die table 4 screwed, which are provided with springs 8.
- This Screw plugs 7 are in the same Radial bores 22 as the associated ones Die holder 5. Press during the fixation process Matrix pins 6 of the matrix holder 5 against the springs 8 of the screw plug 7, so that the springs 8 after the Fixation process are compressed. Should the matrices 10 are replaced, the hydraulic Device switched off so that over the Pressure feed 9 no more force on the die holder 5 is exerted in the direction of the matrices 10. Around However, to release the dies 10, the die holder 5 can be moved away from the matrices 10. The when fixing compressed springs 8 of the screw plugs 7 relax and press the die holder 5 off the matrices 10 radially inwards. This happens for all matrices 10 at the same time. The matrices 10 can then be taken out of the die table 4, the new matrices 10 can be used and with Help the hydraulic device at the same time be fixed. This makes it easier and faster Machine cleaning process or die change.
- matrices 10 consists in the formation of the Die holder 5 as cams on one in the die table 4 mounted circular washer, which for example a pinion is driven.
- Another mechanical embodiment is the training the die holder 5 as by spring elements spread, pivoted in the matrix table 4 Lever pairs.
- the levers are radial Push rods actuated from the inside.
- the formation of the die holder is also possible 5 as radially from the inside against the matrices 10 movable circle segments.
- the circle segments are with slanted oblong holes.
