Definitions

  • the present invention relates to a device for deburring and dedusting compressed products from the pharmaceutical industry, namely tablets or pills.
  • Devices which are connected directly after the tablet presses in the tablet production process. These devices work according to the vibration principle by vibrating the tablets on perforated plates, which means that the tablet surfaces are subjected to mechanical stress, which causes them to be deburred.
  • the conventional tablet deburrers have a plurality of perforated plates arranged one above the other, each having a hole through which the tablets, after a certain dwell time during which they are moved to the hole due to the vibrations, are arranged on the next lower one Plate falling. The same process is repeated on the lower-lying plate until the tablets have finally fallen through the hole in the bottom plate.
  • the tablets are showered with compressed air for three meters of vibration and then leave the device via a dust-free zone created in a counter-air flow, after which they are separated and packaged.
  • the vibration is generated by means of an electromagnet, which attracts the perforated plates against the force of leaf spring assemblies at a certain frequency. With a phase control on the electromagnet, the intensity of the vibration can be regulated continuously.
  • Such tablet deburrers and dust collectors can be mounted on height-adjustable tripods or on a swivel arm. They work with an extremely high level of operational reliability and are practically maintenance-free, which is of crucial importance for the uninterrupted production process of around 4-500,000 tablets per hour over long periods.
  • the basic disadvantage of these conventional devices is that the tablets move downwards during deburring and dedusting and thus lose height that could otherwise be used for further transport due to gravity.
  • the use of the tablet deburrer therefore requires a conveyor system in order to convey the tablets upwards, either before or after deburring and dust removal, by the amount lost in the tablet deburrer.
  • a conveyor system means an additional cost and also an additional space requirement in the production chain.
  • the conveyor system has a certain risk of failure and requires maintenance.
  • the pharmaceutical industry has Therefore, the desire for a tablet deburrer and dust extractor has been expressed for a long time, which does not result in a loss of height in the conveying process and nevertheless has a minimal risk of failure.
  • it should be as compact and cost-effective as possible, and deburr and dust-free the tablets with minimal risk of failure, the tablets still gaining head.
  • the assembled device according to the invention is shown in a cross section viewed from the side. Its essential element is the helical path 1, which with its inner edge 4 winds around the outside of a carrier tube 2.
  • the tablets 8 are conveyed on this path 1.
  • the web 1 is advantageously made of chrome steel and forms a channel by having a kink in the middle in the cross section. This measure ensures that the majority of the tablets are transported in a lying position. Even if individual tablets sometimes jump into an upright position as a result of the vibrations, they will return to a lying position within a short time due to this channel shape. This kink also ensures that the tablets never jam on the track.
  • a jacket tube 3 is fitted over the carrier tube 2 and the web 1 winding upwards on its outside, which is advantageously made of plexiglass and thus provides an insight into the web 1.
  • a cover 14 is placed on the upper end of the casing tube 3 and has a pouring spout 18 where the web 1 ends.
  • the support tube 2 and the casing tube 3 are constructed on a base plate 11.
  • a round rod 15 with end threads 16, 17 runs along the axis of the central support tube 2 and the casing tube 3. The round rod 15 is firmly screwed to the base plate 11 by means of the thread 17.
  • a cover 13 placed, which braces the carrier tube 2 via the round rod 15 with the base plate 11 by means of a screw cap 20.
  • the casing tube 3 is also closed with a cover 14 and is indirectly clamped to the base plate 11 via a further screw cap 21, which is screwed onto the end of the first screw cap 20.
  • a muzzle ring 22 adjoins the casing tube 3, so that a sealed partition wall 25 is formed between the area below and above the muzzle ring 22.
  • the mouth ring 22 in turn lies tightly on a plate 23 which rests directly on the base plate 11 and from which a nozzle 24 leads to the suction device (not shown).
  • the carrier tube 2 is permeable to air, for example by being perforated or provided with slots. In this way, a suction can be generated through the nozzle 24 in the interior of the carrier tube 2, so that the dust between the carrier tube 2 and the jacket tube 3, which arises as a result of the tablets 8 rubbing against one another in this region 5, continuously through the wall of the carrier tube 2 can be sucked through inside and then down through the nozzle 24.
  • the base plate 11, which carries the entire construction described so far, is mounted on three leaf spring assemblies 12 which are fastened at the bottom on a base 9, the leaf spring assemblies 12 being distributed around the circumference of the base plate 11 and thereon at an oblique angle, for example are arranged at a 45 ° angle to the base plate or its normal.
  • the electromagnet 10 and the leaf spring packets 12 are accommodated in a cylindrical housing 7.
  • the electromagnet 10 pulls the base plate 11 against it by means of magnetic force the leaf spring assemblies 12 are curved downward against their spring force, which at the same time causes the base plate 11 to rotate slightly. In the example shown, when looking at the base plate 11 from above, this rotation takes place when the base plate 11 is pulled down in a clockwise direction.
  • the electromagnet 10 is switched off, the base plate 11 snaps back into its original position due to the springs 12 in exactly the opposite direction.
  • the described movement of the base plate 11 is transferred to the entire arrangement which it carries, resulting in a movement of, for example, approximately 4 mm amplitude, which has a horizontal component because of the rotation and a vertical component because of the up and down movement of the base plate 11.
  • the tablets 8 pass through the pouring channel 19 at the very bottom of the web 1.
  • they are thrown obliquely forwards and upwards by each movement cycle with respect to the web and finally land on the web 1 due to their inertia
  • the frequency and amplitude of the vibration naturally depend on the natural frequency of the entire arrangement and can be regulated by means of a control of the electromagnet.
  • a typical one Frequency is of the order of magnitude of approximately 25 Hz.
  • this device thus causes the tablets 8 to be properly vibrated over a relatively long period of time and to lose any burrs as a result of the mechanical stress suffered in the process.
  • the processed burrs are continuously extracted in the form of dust from the area 5 through the wall of the carrier tube 2 in the manner already described, so that the tablets 8 are finally deburred on the upper pouring spout 18 of the device after a hopping hike over the entire length of the web and dusted out.
  • no delivery head was lost, but on the contrary, delivery head was gained by the tablets 8 jumping upwards on the helical path 1 according to the invention due to the typical vibration.
  • the serpentine web 1 can extend over many turns and thereby several meters, as shown, and ensure a correspondingly high dwell time and therefore processing time for the individual tablets.
  • the conveying speed allows several 100,000 tablets to be deburred and dedusted per hour.
  • FIG. 2 shows the individual elementary components of the device according to the invention in a disassembled state.
  • the cover 14 of the casing tube 3 with the pouring spout 18 can be seen starting from above, including the casing tube 3 itself, which has a pouring spout 19 at the bottom, and that below muzzle ring 22 adjoining the casing tube 3.
  • the base 9 with the cylindrical housing 7 built thereon, in which the electromagnet and the leaf spring assemblies are located, as well as the base plate 11 closing at the top.
  • the two screw closures 20, 21 shown.
  • the support tube 2 closed at the top with the cover 13 is shown with the helical path 1 which winds around the support tube 2.
  • the present device according to the invention for deburring and dusting tablets can be made extremely compact and therefore takes up little space in the production chain.
  • the device simultaneously conveys the tablets to a higher position, thereby gaining valuable head, so that a separate conveyor system can be dispensed with.
  • the device is extremely reliable in operation and practically maintenance-free, since it has no mechanically moving parts in the classic sense.
