Definitions
- the invention relates to a device for deburring and dedusting tablets or pills fed from a tablet press according to the preamble e of claim 1.
- the sieve drum is rotatable and inclined, so that when the sieve drum is rotated, the tablets or pills are conveyed through the ⁇ drum due to the force of gravity and the burrs are mutually ground due to the constant friction of the tablets or pills against one another.
- baffles represent baffles that one
- the object of the invention is that the jacket of the screen drum consists of two angled sections which are angled to form coherent surfaces 7 which run longitudinally to the center axis of the screen drum, arranged in the longitudinal direction of the screening drum and 8 offset to each other transversely and each section forms one half of the shell, the 9 adjacent longitudinal edges of the sections each leaving an outwardly open longitudinal gap (a) over the length of the sections, the wider is the 1 largest diameter of the individual tablet or pill, with the inner longitudinal edges of the sections forming falling edges over which the tablets or 3 pills slide when the sieve drum rotates and onto the underlying one ⁇ fall section of the jacket.
- the areas of the sections are advantageous in themselves
- the device according to the invention has the salient advantage that with this relatively small-volume, loose bulk goods of a general nature, in particular tablets or pills or suppositories from a press, they are treated completely and quickly by rubbing, such as deburring and / or dusting, whereby only a 12 short way is necessary.
- rubbing such as deburring and / or dusting
- the individual objects of the bulk material fall down one or more falling edges each time the drum is turned. Because of these falling edges and the fact that the surfaces of the sections are flat or slightly curved in a concave manner, it is advantageously achieved that the individual ⁇ objects of the bulk material overtake each other, so that subsequent, later falling objects of the bulk material fall down those counter
- the sieve drum is used at the same time to convey the tablets or pills through it, it can be inclined in the form of an inclined plane.
- the rotary movement of the sieve drum can also advantageously take place in a multitude 3 of small, predeterminable steps of small to very small rotation angle per step 4, which are impressed on the sieve drum as more or less easy rattling or 5 as vibration, which causes the friction of the tablets with each other and the 6 individualization of the tablets additionally supported.
- the stepper motor can, for example, regulate between 1 and 10 steps per second, the sieve drum, for example, between 0.1 and 10 U / sec. In this way 9 tablets or pills can be processed completely product-related according to the specific parameters of the tablets or pills.
- the sieve drum is given no or only a slight vibration; in the case of hard objects, a correspondingly adapted vibration; in addition, the speed of rotation of the sieve drum can be adjusted accordingly.
- Figure 1 is a view of a screen drum, the jacket of two parts
- FIG. 2 shows a view of the sieve drum along the section line A-A with the housing partially broken away and ⁇ FIGS. 3a-3d show the principle of a sieve drum in different positions in order to show the movements of the tablets in different positions.
- a sieve drum 25 is rotatably mounted about an axis of rotation, the
- 14 jacket of the screen drum 25 is open-spirally curved and can consist of one piece, so that the two edges 26 and 27, preferably along a length line, face each other at a distance b and overlap and form a longitudinal gap b in between ⁇ .
- the sieve drum 25 rotates in the direction of the curved arrow 32 in a clockwise direction such that the tablets always from
- the tablets or pills are either a metal detection station i tion or a test facility for testing the tablets according to specific parameters.
- FIGS. 1 and 2 show an example of a technical configuration of the pre
- This consists of an elongated cylindrical sieve drum 2, wherein
- the retaining ring 7 carries a ring gear 10 for rotating the sieve drum 2, the retaining ring 8 has a circumferential groove 11 into which a wheel, not shown, for ex-
- sieve drum 2 is connected and which serves as a pulsation damper.
- This pipe section 9 effectively collects or accumulates tablets at the transition i ⁇ from the sieve drum into the pipe section 9 and the tablets ⁇ are separated.
- the length of the tube 9 with respect to the screening drum 2 is preferably between one fifth and one third.
- the sieve drum 2 is installed in a preferably closed, shell-shaped or cylindrical 5-shaped housing 1, which has an inclined bottom 5 with an outlet funnel 14 for suction of the dust or the bulk material.
- the housing 1 has a filling funnel 15 protruding through the front cover surface of the screening drum 8 2 into the same for filling the screening drum 2.
- the screening drum 2 is preferably arranged obliquely, the filling funnel 15 1 being arranged 2 at the upper end and the pipe section 9 at the lower end of the screening drum 2.
- the tablets, pills or the bulk material thus pass through the sieve drum 3 2 due to gravity and the circulating movements.
- the jacket of the screening drum 2 consists of two sections 3, 4, each in the
- flanks 18 19-20 21, 22, which are angled, the flanks 18 and
- the surfaces 19, 22 represent beveled areas between the ⁇ surfaces 18, 20 and 20, 21; those surfaces 19 and 22 of the sections 3, 4, 7 which are inclined to the mutually perpendicular surfaces 18, 20, 21, s have a different width.
- the sections 3, 4 are joined so as to be offset transversely to the central axis 17 of the screening drum 2 in such a way that the longitudinal edge 23 of the surface 18 lies outside and the longitudinal edge 23 'of the surface 21 lies within the volume of the screening drum 2; or the longitudinal edge 24 of the section 4 lies inside and the longitudinal edge 24 'of the section 4 lies outside the volume; the longitudinal edges 23 and 24 or 23 'and 24' overlap.
- the sections can also consist of three flat surfaces, the e transitions between the individual surfaces being formed by a curved surface.
